`
`BACKGROUNDOF THE INVENTION
`
`[0002]
`
`Time division-code division multiple access (TD-CDMA)
`
`is an air
`
`interface technology that combines the benefits of the three elemental concepts in a
`
`universal mobile telecommunication system (UMTS): time division multiple access
`
`(TDMA); code division multiple access (CDMA); and time division duplex (TDD).
`
`TDD, in particular, uses the same radio channel for both uplink and downlink
`
`communications, and discriminates between signals by separating the transmissions
`
`in time. One of the benefits obtained by operating both links on the same frequency
`
`is the ability to exploit channel reciprocity.
`
`[0003]
`
`Channel reciprocity gives equipment the ability to derive information
`
`about uplink channel conditions from downlink channel conditions based upon
`
`signals received by the user equipment (UE). Pathloss is one example of channel
`
`information that can be obtained from channel reciprocity. Knowledge of the uplink

`

`
`pathloss enables open-loop power control to be employed for uplink transmissions.
`
`For example, uplink power control is important for the operation of the CDMA
`
`element of TD-CDMA asit counteracts the near-far effect that would otherwise be
`
`encounteredif all UEs transmitted at a fixed power regardless of the uplink pathloss.
`
`[0004]
`
`The open-loop uplink power control feature provides a significant
`
`advantage when coupled with a multiple access data transmission system that is used
`
`for packet-based communication and/or shared channels. When accessto a limited
`
`number of uplink channels is shared between a large population of terminals it is
`
`imperative that access to the channels can be switched between terminals with
`
`minimal latency. A data terminal that can derive information needed to access uplink
`
`channels from the downlink transmissions (beacon signals) has a significant
`
`advantage over a terminal thatrelies on the (dengthy) configuration of a dedicated
`
`channel in order to establish a feedback channel.
`
`[0005]
`
`However, channel
`
`reciprocity cannot always be guaranteed.
`
`For
`
`example TDD transmissions may not be permitted in certain frequency spectrum
`
`allocations; this is a regulatory issue and may be used to protect other wireless
`
`equipment in the same or adjacent frequency bands.
`
`In these situations the
`
`correlation between uplink and downlink channels is lost because the channels are
`
`transported on carrier frequencies that are separated in frequency by an amount that
`
`is greater than the coherence bandwidth of the channel (usually, only a few MHz
`
`separation is sufficient to cause the uplink and downlink fading profiles to be
`
`independent).
`
`[0006]
`
`In high speed mobile applications, the time delay between downlink and
`
`uplink transmissions may exceed the coherence time of the channel. The maximum
`
`time delay that can be tolerated is a function of the mobile speed and the RF carrier
`
`frequency used, with the coherence time reducing with increasing speed and RF
`
`carrier frequency. Also, the use of multiple transmit and/or receive antennas at the
`
`network and/or the mobile terminal can introduce unintentional decorrelation
`
`between the uplink and downlink channels.

`
`If the TD-CDMA airinterface is to be used in applications where the
`
`correlation between the uplink and downlink path loss is not guaranteed, then it
`
`would be advantageousto find a substitute for channelreciprocity.
`
`BRIEF SUMMARYOF THE INVENTION
`
`[0008]
`
`Although it is desirable to support air interfaces where the pathloss is
`
`not reciprocal, known conventional methods do not deal directly with the evolution or
`
`adaptation of an air interface that uses channelreciprocity to deliver key features
`
`and advantages where channel reciprocity 1s not guaranteed. The adaptation
`
`provided in embodiments of the invention introduces a new technique for uplink
`
`channel control that uses a feedback scheme as a substitute for the absence of channel
`
`reciprocity, with minimal impact on the ability of the air interface to support uplink
`
`shared channels.
`
`[0009]
`
`Embodiments of the present invention enable active feedback control
`
`between a base station and user equipment (UE).
`
`In particular, the operation of a
`
`system designed for TDD, or unpaired operation, is expanded to operate in FDD, or
`
`paired, mode. For example, an uplink beacon function (for power control) and a
`
`modified random access process substitute for the information lost due to the lack of
`
`channel reciprocity in paired operation. Embodiments of the invention allow a
`
`terminal
`
`to transmit
`
`the uplink physical channel control signal
`
`(UL_Beacon)
`
`independently from the uplink physical channel. Therefore, the implementation of
`
`closed loop feedback may operate in the absence of an uplink physical channel.
`
`In
`
`one embodiment, a UE allocates a time slot for a beacon signal separated from the
`
`time slots for datain a frame. A second time slot is allocated within the framefor the
`
`base station to transmit a control signal in response to the beacon signal. The control
`
`signal instructs the UE to adjust a transmission parameter.
`
`[0010]
`
`A UL_Beacon signal may be combined with a physical layer common
`
`control channel (PLCCH)to form a feedback system. A dedicated timeslot groups all
`
`of the UL_Beacon signals from multiple UEs in a specific uplink timeslot. By
`
`7456619.1
`
`-3-
`
`Ex.1002 / Page 14 of 164
`TESLA,INC.
`
`

`

`IPW2-USCN213571
`
`grouping the UL_Beacon signals together, embodiments obtain separation between
`
`the UL_Beacon signals and the standard uplink physical channels. Additionally, in
`
`a synchronous system embodiments of
`
`the invention detect and cancel
`
`the
`
`UL_Beaconsignals from othercell sites Gnter-cell interference). The PLCCH carries
`
`feedback information to the UEs that are transmitting UL_Beacon signals. The
`
`PLCCH can share a timeslot with other physical channels by exploiting the CDMA
`
`aspect of the system.
`
`[0011]
`
`In other embodiments, the number of supported UEs can be increased
`
`by fractionating the use of the UL_Beacon and PLCCHacross a multiframe period.
`
`Fractionation may also prevent timeslot blocking where half duplex UEs have a long
`
`UL/DL switching time. Additionally, support for half duplex terminals is implicit due
`
`to the nature of the TDMA frame structure. The system may managetheallocation
`
`of resource across the population of terminals such that the full capacity of the base
`
`station can be utilized even when only half-duplex terminals are deployed.
`
`In
`
`embodiments of the invention, full-duplex terminals can be still be supported along
`
`with half duplex UEs.
`
`[0012]
`
`Moreover,
`
`in other embodiments, a radio resource control
`
`(RRC)
`
`connected state covers the subset of terminals that are in cell forward access channel
`
`(Cell_FACH), which are also transmitting UL_Beacon and receiving PLCCH, thus
`
`creating an active control feedback channel. Management of the UEs that are in
`
`Cell_Active state may remove users that are less active, and may add users that are
`
`newly active while retaining users that may have on-going data transfer
`
`requirements.

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`[0018]
`
`Figure 1 illustrates an example of a cellular communication system
`
`according to embodimentsof the invention. The network includes a user equipment
`
`(UE) domain, a radio access network (RAN) domain, and a core network domain. The
`
`UE domain includes user equipment 110 that communicate with at least one base
`
`station 112 in the RAN domainvia a wireless interface. The RAN domain mayalso
`
`include a network controller (RNC) 118 (e.g., radio network controller), such as that
`
`usedin UMTSsystems. Alternatively, such functionality maybe distributed between
`
`the Node Bs and an access gateway (AGW) (mot shown)or othercontroller in the core
`
`network. FIG. 1 also illustrates an optional radio resource manager (RRM) 114. The
`
`RRM mayperform functions otherwise performed by the Node Bs or an AGW in some
`
`embodiments.
`
`[0019]
`
`The core network (CN) 116 includes, in this example, a serving GPRS
`
`support node (SGSN) 120, and a gateway GPRS support node (GGSN) 122. The core
`
`network is coupled to an external network 124. The SGSN 120 is responsible for
`
`session control, including keeping track of the location of the UEs. The GGSN 122
`
`concentrates and tunnels user data within the core network 116 to the ultimate
`
`destination (e.g., an Internet service provider) in the external network 124. Further
`
`details may be found in the 3GPP UMTStechnical specifications, such as TS23.246
