`
`1. Scope
`
`This recommendation defines the physical channels of the radio sub-system
`required to support the logical channels. It includes a description of
`the logical channels and the definition of frequency hopping, TDMA
`frames, timeslots and bursts.
`
`2. General
`
`The radio subsystem is required to support a certain number of logical
`channels that can be separated into two overall categories as defined in
`recommendation 04.03:
`
`i)
`
`The traffic channels (TCH's).
`
`ii) The control channels.
`
`More information is given about these logical channels in section 3 which
`also defines a number of special channels used by the radio sub-system.
`
`Section 4 of this document describes the physical resource available to
`the radio sub-system, section 5 defines physical channels based on that
`resource and section 6 specifies how the logical channels shall be mapped
`onto physical channels. Figure 1 depicts this process.
`
`3. Logical channels
`
`3.1 General
`
`This section describes the logical channels that are supported by the
`radio subsystem.
`
`3.2 Traffic channels
`
`3.2.1 General
`
`Traffic channels (TCH's) are intended to carry either encoded speech or
`user data. Two general forms of traffic channel are defined:
`
`(i) Full rate traffic channel (TCH/F). This channel carries information
`at a gross rate of 22.8 kbits/s.
`
`(ii) Half rate traffic channel (TCH/H). This channel carries information
`at a gross rate of 11.4 kbit/s.
`
`The specific traffic channels available in the categories of speech and
`user data are defined in the sections following.
`
`3.2.2 Speech traffic channels
`
`The following traffic channels are defined to carry encoded speech:
`
`(i)
`
`Full rate traffic channel for speech (TCH/FS).
`
`(ii)
`
`Half rate traffic channel for speech (TCH/HS).

`
`3.2.3 Data traffic channels
`
`The following traffic channels are defined to carry user data :
`
`( i)
`
`( ii)
`
`(iii)
`
`(iv)
`
`(v)
`
`Full rate traffic channel for 9.6 kbit/s user data
`(TCH/F9. 6) ..
`
`Full rate traffic channel for 4.8 kbit/s user data
`(TCH/F4. 8) .
`
`Half rate traffic channel for 4.8 kbit/s user data
`(TCH/H4. 8).
`
`Half rate traffic channel for S 2.4 kbit/s user data
`(TCH/H2. 4) .
`
`Full rate traffic channel for S 2.4 kbit/s user data
`(TCH/F2.4)
`
`3.3 Control channels
`
`3.3.1 General
`
`These channels are intended to carry signalling or synchronization data.
`Three categories of control channel are defined: broadcast, common and
`dedicated. Specific channels within these categories are defined in the
`sections following.
`
`3.3.2 Broadcast channels
`
`(i) Frequency correction channel (FCCH): this channel carries information
`for frequency correction of the mobile station. It is required only
`for the operation of the radio sub-system.
`
`(ii) Synchronization channel (SCH): this channel carries information for
`frame
`synchronization of the mobile station and identification of a
`base transceiver station. It is required only for the operation of
`the radio sub-system. Specifically the synchronization channel shall
`contain two encoded parameters:
`
`a.) Base transceiver station identity code (BSIC): 6 bits (before channel
`coding) consists of 3 bits of PLMN colour code with range 0 to 7
`and 3 bits of BS colour code with range 0 to 7 as defined in
`recommendation 03.03.
`
`b.) Reduced TDMA frame number (RFN): 19 bits (before channel coding)
`
`T1
`T2
`T3'
`
`(11 bits)
`(5 bits)
`(3 bits)
`
`range 0 to 2047
`range 0 to 25
`range 0 to 4
`
`FN div ( 26 x 51)
`FN mod 26
`(T3 - 1) div 10
`
`where
`
`and
`
`T3
`
`(6 bits)
`
`range 0 to 50
`
`FN mod 51

`Version 3.8.0
`
`FN = TDMA frame number as defined in section 4.3.3.
`
`Recommendations 04.06 and 04.08 specify the precise bit ordering,
`recommendation 05.03 the channel coding of the above parameters and
`recommendation 05.10 defines how the TDMA frame number can be calculated
`from Tl, T2, and T3'.
`
`: this channel broadcasts general
`(iii) Broadcast control channel (BCCH)
`information on a base transceiver station per base transceiver
`station basis. Of the many parameters contained in the BCCH,
`the
`following parameters, as defined in recommendation 04.08 are
`referenced later in this document:
`
`a.) The organization of the common control channels CCCH CONF.
`From this parameter, the number of common control channels ( BS_CC_CHANS),
`and whether or not CCCH or SDCCH are combined ( BS_CCCH_SDCCH_COMB
`true or false) are derived as follows:
`
`CCCH_CONF
`000
`001
`010
`100
`110
`
`BS_CC_CHANS
`1
`1
`2
`3
`4
`
`BS_CCCH SDCCH_COMB
`false
`true
`false
`false
`false
`
`b.) The number of blocks on each common control channel
`reserved for access grant messages (BS_AG_BLKS_RES)
`3 bits (before channel coding) range 0 to 7.
`
`c.) The number of 51 TDMA frame multiframes between
`transmissions of paging messages to mobiles of the
`same paging group (BS_PA_MFRMS): 3 bits (before
`channel coding) range 2 to 9.
`
`The above parameters use is detailed in section 6.5.
`
`3.3.3 Common control type channels, known when combined as a
`common control channel (CCCH) :
`
`(i)
`
`(ii)
`
`Paging channel (PCH) Downlink only, used to page
`mobiles.
`
`Random access channel (RACH): Uplink only, used to
`request allocation of a SDCCH.
`
`(iii) Access grant channel (AGCH): Downlink only, used to
`allocate a SDCCH or directly a TCH.
`
`3.3.4 Dedicated control channels
`
`(i)
`
`Slow, TCH/F associated, control channel (SACCH/TF)
`
`(ii)
`
`Fast, TCH/F associated, control channel (FACCH/F)
`
`(iii) Slow, TCH/H associated, control channel (SACCH/TH)
`
`(iv)
`
`Fast, TCH/H associated, control channel (FACCH/H)
`
`(v)
`
`Stand alone dedicated control channel (SDCCH/8)
`
`(vi)
`
`Slow, SDCCH/8 associated, control channel

`
`(vii) Stand alone dedicated control channel, combined
`with CCCH
`(SDCCH/4)
`
`(viii) Slow, SDCCH/4 associated, control channel
`(SACCH/C4)
`
`3.3.5 Cell Broadcast Channel (CBCH)
`
`The CBCH, downlink only, is used to carry the short message service cell
`broadcast (SMSCB). The CBCH uses the same physical channel as the SDCCH.
`
`3.4 Combination of channels
`
`Only certain combinations of channels are allowed as defined in
`recommendation 04.03. Section 6.4 lists the combinations in relation to
`basic physical channels (defined later) .
`
`4. The physical resource
`
`4.1 General
`
`The physical resource available to the radio sub-system is an allocation
`of part of the radio spectrum. This resource is partitioned both in
`frequency and time. Frec~ency is partitioned by radio frequency channels
`(RFCHs) divided into bands as defined in recommendation 05.05. Time is
`partitioned by timeslots and TDMA frames as defined in this document in
`section 4.3.
`
`4.2 Radio frequency channels
`
`4.2.1 Cell allocation and mobile allocation
`
`Recommendation 05.05 defines radio frequency channels (RFCHs), and
`allocates numbers to all the radio frequency channels available to the
`system. A subset of these channels, defined as the cell allocation (CA),
`are allocated to a particular cell. One radio frequency channel of the
`cell allocation shall be used to carry synchronization information and
`the BCCH,
`this shall be known as BCCH carrier. The subset of the cell
`allocation, allocated to a particular mobile, shall be known as the
`mobile allocation (MA)
`
`4.2.2 Downlink and uplink
`
`The downlink comprises radio frequency channels used in the base
`transceiver station to mobile station direction.
`
`The uplink comprises radio frequency channels used in the mobile station
`to base transceiver station direction.
`
`4.3
`
`Timeslots and TDMA frames
`
`4.3.1 General
`
`A timeslot shall have a duration of 3/5200 seconds (~577 ~s). Eight
`timeslots shall form a TDMA frame (~4.62 ms in duration).
`
`At the base transceiver station the TDMA frames on all of the radio
`frequency channels
`in the downlink shall be aligned. The same shall
`apply to the uplink
`(see recommendation 05.10).
`
`Ericsson Exhibit 1006
`Page 8
`
`

`

`ETSI/GSM
`
`GSM 05.02 /8
`
`Version 3.8.0
`
`At the base transceiver station the start of a TDMA frame on the uplink
`is delayed by the fixed period of 3 timeslots from the start of the TDMA
`frame on the downlink (Figure 2).
`
`At the mobile station this delay will be variable to allow adjustment for
`signal propagation delay. The process of adjusting this advance is known
`as adaptive frame alignment and is detailed in recommendation 05.10.
`
`{The staggering of TDMA frames used in the downlink and uplink is in
`order to allow the same timeslot number to be used in the downlink and
`uplink whilst avoiding the requirement for the mobile station to transmit
`and receive simultaneously. The period includes time for adaptive frame
`alignment, transceiver tuning and receive/transmit switching (Figure 4) .}
`
`4.3.2 Timeslot number
`
`The timeslots within a TDMA frame shall be numbered from 0 to 7 and a
`particular timeslot shall be referenced by its timeslot number (TN) .
`
`4.3.3 TDMA frame number
`
`TDMA frames shall be numbered by a frame number (FN) . The fr~~e number
`shall be cyclic and shall have a range of 0 to FN_MAX where ?N_MAX = (26
`x 51 x 211) -1 = 2715647 as defined in recowmendation 05.10. The frame
`number shall be incremented at the end of each TDMA frame.
`
`The complete cycle of TDMA frame numbers from 0 to FN_MAX is defined as a
`hyperframe. A hyperframe consists of 2048 superframes where a superframe
`is defined as 26 x 51 TDMA frames. A 26 TDK~ frame multiframe is used to
`support traffic and associated control channels and a 51 TDK~ frame
`multiframe is used to support broadcast, cowmon control and stand alone
`dedicated control (and their associated control) channels. Hence a
`superframe may be considered as 51 traffic/associated control multiframes
`or 26 broadcast/common control multiframes.
`
`{ The need for a hyperframe of a substantially longer period than a
`superframe arises from the requirements of the encryption process which
`uses FN as an input parameter. }
`
`5. Physical channels
`
`5.1 General
`
`A physical channel uses a combination of frequency and time division
`multiplexing and is defined as a sequence of radio frequency channels and
`time slots. The complete definition of a particular physical channel
`consists of a description in the frequency domain, and a description in
`the time domain.
`
`The description in the frequency domain is addressed in section 5.4, the
`description in the time domain is addressed in section 5.5.

`
`5.2.8 Guard period
`
`{ It is required of mobile stations that the transmitted amplitude of a
`burst is approximately constant over the useful period of a burst. It is
`also required of a mobile that transmission be attenuated for the period
`between bursts with the necessary ramp up and down occurring during the
`guard periods as defined in recommendation 05.05. A base transceiver
`station is not required to ramp down and up between adjacent bursts. In
`any case where the amplitude of transmission is ramped up and down,
`then
`by applying an appropriate modulation bit stream interference to other RF
`channels can be minimized }
`
`5.3 Physical channAls and bursts
`
`The description of a physical channel will be made in terms of timeslots
`and TDMA frames and not in terms of bursts. This is because there is not
`a one co one mapping between a particular physical channel, and the use
`of a particular burst.

`
`5.4 Radio frequency channel sequence
`
`The radio frequency channel sequence is determined by a function that, in
`a given cell (with a given set of general parameters, see section 5.6.2
`), with a given timeslot number (TN), a given mobile radio frequency
`channel allocation (MA) and a given mobile allocation index offset
`(MAIO), maps the TDMA frame number (FN)
`to a radio frequency channel.
`
`In a given cell there is therefore, for a physical channel assigned to a
`particular mobile, a unique correspondence between radio frequency
`channel and TDMA frame number.
`
`The detailed hopping generation algorithm is given in section 6.2
`
`5.5 Timeslot and TDMA frame sequence
`
`A given physical channel shall always use the same timeslot number in
`every TDMA frame. Therefore a timeslot sequence is defined by:
`
`(i)
`
`a timeslot number (TN) and
`
`(ii) a TDMA frame number sequence.
`
`The detailed definitions of TDMA frame number sequences are given in
`section 7.
`
`The physical channels where the TDMA frame number sequence is 0,1 ...
`FN_MAX (where FN_MAX is defined in section 4.3.3) are called 'basic
`physical channels'.
`
`5.6 Parameters for channel definition and assignment
`
`5.6.1 General
`
`This section describes the set of parameters necessary to describe fully
`the mapping of any logical channel onto a physical channel. These
`parameters may be divided into general parameters, that are
`characteristic of a particular base transceiver station, and specific
`parameters, that are characteristic of a given physical channel.
`
`5.6.2 General parameters
`
`These are:
`
`(i)
`
`(ii)
`
`the set of radio frequency channels used in the cell
`(CA), together with the identification of the BCCH
`carrier.
`
`the TDMA frame number (FN) {which can be derived from
`the reduced TDMA frame number (RFN) which is in the
`form Tl,T2,T3', see 3.3.2}.
`
`These parameters are broadcast ( or derived from parameters broadcast )
`in the BCCH and SCH.
`
`5.6.3 Specific parameters
`
`These parameters define a particular physical channel in a base
`transceiver station. They are:

`The last two parameters allow the determination of the frame sequence.
`
`6. Mapping of logical channels onto physical channels
`
`6.1 General
`
`The detailed mapping of logical channels onto physical channels is defined
`in the following sections. Section 6.2 defines the mapping from TDMA frame
`number (FN) to radio frequency channel (RFCH). Section 6.3 defines the
`mapping of the physical channel onto TDMA frame number. Section 6.4 lists
`the permitted channel combinations and section 6.5 defines the operation
`of channels and channel combinations.
`
`6.2 Mapoinq in freauencv of logical channels onto ohvsical
`channels
`
`6.2.1 General
`
`The parameters used in the function which maps TO~~ frame number onto
`radio frequency channel are defined in section 6.2.2. The definition of
`the actual mapping function, or as it is termed, hopping sequence
`generation is given in 6.2.3.
`
`6.2.2 Parameters
`
`The following parameters are required in the mapping from TDMA frame
`number to radio frequency channel for a given assigned channel.
`
`General parameters of the BTS, specific to one BTS, and broadcast in the
`BCCH and SCH:
`
`(i)
`
`CA
`
`Cell allocation of radio frequency channels.
`
`(ii)
`
`FN
`
`TDMA frame number, broadcast in the SCH,
`formTl,T2,T3' (see section 3.3.2).

`
`For a given set of parameters, the index to a radio frequency channel
`within the mobile allocation (K~I from 0 to N-1, where MAI=O represents
`the lowest RF channel in the mobile allocation), is obtained with the

`
`6.2.4 Specific cases
`
`(CO), frequency hopping is not pe~mitted on
`On the RFCH carrying a BCCH
`any timeslot supporting a BCCH according to table 3 of section 7. A non(cid:173)
`hopping radio frequency channel sequence is characterized by a mobile
`allocation consisting of only one radio frequency channel, ie with N=l,
`MAIO=O. In this instance sequence generation is unaffected by the value
`of the value HSN.
`
`6.2.5 Change in the frequency allocation of a base transceiver
`station
`
`The consequence of adding or removing a number of radio frequency
`channels in a base transceiver station is a modification of the cell
`allocation (CA) and the mobile allocation (MA) . In order to achieve this
`without disruption to mobile stations with currently assigned channels it
`is necessary to send a message to all mobiles with assigned channels. The
`message, as defined in 04.08, will contain a new cell allocation (if
`necessary), mobile allocation and a time (in the form of a TD~ffi frame
`number) at which the change is to occur. A new cell allocation may not be
`necessary if channels are only being removed, and not added.
`
`6.3 Mapninq in time of loaical channels onto nhysical channels
`
`6.3.1 General
`
`The mapping in time of logical channels is defined in the tables of section 7,
`which also defines the relationship of the air interface frames to the
`multiframe .
`
`6.3.2 Key to the mapping table of section 7
`
`The following relates to the tables of section 7. The columns headed:
`
`(i)
`
`'Channel designation' gives the precise ac~onym for the channel to
`which the mapping applies.
`
`(ii)
`
`'Sub-channel number' identifies the particular sub-channel being
`defined where a basic physical channel supports more than one
`channel of this type.
`
`(iii) 'Direction' defines whether the mapping given applies identically
`to downlink and uplink (D&U), or to downlink (D) or uplink (U)
`only.
`
`(iv)
`
`'Allowable timeslots assignments' defines whether the channel can
`be supported on, or assigned to, any of the timeslots, or only on
`specific timeslots.
`
`(v)
`
`'Allowable RF channel assignments' defines whether the channel can
`use any or all of the radio frequency channels in the cell
`allocation (CA), or only the BCCH carrier (CO). It should be noted
`that any allocated channel ex within CA could be any radio
`frequency channel, and that no ordering of radio frequency channel
`number is implied. For example, allocated channel CO need not have
`the lowe5t radio frequency channel number of the allocation.
`
`(vi)
`
`'Burst type' defines which type of burst as defined in section 5.2
`is to be used for the physical channel.

`

`
`Version 3.8.0
`
`'Repeat length in TO~~ frames' defines how many TDMA frames occur
`(vii)
`before the mapping for the interleaved blocks repeats itself eg.
`51.
`
`viii) 'Interleaved block TDMA frame mapping' defines, within the
`parentheses, the TDMA frames used by each interleaved block (eg.
`0 ... 3)
`. The numbers given equate to the TDMA frame number (FN)
`modulo the number of TDMA frames per repeat length; Therefore,
`the
`frame is utilized when:
`
`TDMA frame mapping number
`
`(FN )mod repeat length given
`
`Where there is more than one block shown, each block is given a separate
`designation eg. EO, Bl. Where diagonal interleaving is employed then all
`of the TDMA frames included in the block are given, and hence the same
`TDMA frame number can appear more than once (see recommendation 05.03).
`It should be noted that the frame mapping for the SACCH/T channel differs
`according to the timeslot allocated in order to lower the peak processing
`requirements of the BSS.
`
`6.3.3 Mapping of TCH/F9.6, TCH/F4.8, TCH/H4.8 and TCH/H2.4
`
`This paragraph has been deleted.
`
`6.3.4 Mapping of BCCH data
`
`In order to facilitate the MS operation, it is necessary to transmit the
`System Information message in defined BCCH multiframes, as follows (where
`TC = (FN DIV 51) mod (8)):
`
`Message
`
`System Information
`T"ype 1
`Type 2
`Type 3
`T"ype 4
`
`Set when TC
`0
`1
`2 and 6
`3 and 7
`
`Note: (i)
`It is optional what is sent when TC = 4 or 5
`(ii) System Information Type 1 need only be sent if frequency
`hopping is in use. An MS should look for System
`Information Type 1 when TC = 0. If it finds another
`message when TC = 0, it can assume that System
`Information Type 1 is not in use.
`
`6.3.5 Mapping of SID Frames
`
`When the DTX mode of operation is active, it is required to transmit
`Silence Descriptor (SID)
`information, or equivalent dummy information,
`during the SACCH/T block period (104 TDMA frames). As the SID frames do
`not constitute a logical channel and their use is specific to DTX
`operation, the mapping of SID frames onto the TDMA frames is specified in
`Rec. 05.08, 5ection 8.3.

`
`6.5.1 General
`
`(i)
`
`A base transceiver station must transmit a burst in every timeslot
`of every TDHA frame in the downlink of radio frequency channel CO
`of the cell allocation (to allow mobiles to make power
`measurements of the radio frequency channels supporting the BCCH,
`see recommendation OS. 08) . In order to achieve this requirement a
`dummy burst is defined in section 5.2.6 which shall be transmitted
`by the base transceiver station on all timeslots of all TDK~
`frames of radio frequency channel CO for which no other channel
`requires a burst to be transmitted. As an alternative to
`transmitting dummy bursts to fill radio frequency channel CO when
`downlink DTX is activated and the associated traffic frames are
`not scheduled for transmission, the BTS may transmit bursts
`containing parts of the SID frames provided by the speech encoder.
`The bits transmitted in such bursts on the CO carrier shall
`contain the sam
