`
`Transmitter Power Control
`
`4.2.1 General Parameters
`
`Power control is applied for the TDD mode to limit the interference level within the system thus reducing the intercell
`interference level and to reduce the power consumption in the UE.
`
`All codes within one timeslot allocated to the same CCTrCH use the same transmission power, in case they have the
`same spreading factor.

`
`Uplink Control
`
`4.2.2.1
`
`General Limits
`
`During the operation of the uplink power control procedure the UE transmit power shall not exceed a maximum
`allowed value which is the lower out of the maximum output power of the terminal power class and a value which may
`be set by higher layer signalling.
`
`Uplink power control shall be performed while the total UE transmit power is below the maximum allowed output
`power. In some cases the total UE transmit power in a timeslot after uplink power control calculation might exceed the
`maximum allowed output power. In these cases the calculated transmit power of all uplink physical channels in this
`timeslot shall be scaled by the same amount in dB before transmission. The total UE transmission power used shall be
`the maximum allowed output power.
`
`The UTRAN may not expect the UE to be capable of reducing its total transmit power below the minimum level
`specified in [2].
`
`4.2.2.2
`
`PRACH
`
`The transmit power for the PRACH is set by higher layers based on open loop power control as described in [15].
`
`4.2.2.3
`
`DPCH, PUSCH and HS-SICH
`
`The transmit power for DPCH, PUSCH and HS-SICH is set by higher layers based on open loop power control as
`described in [15].
`
`In the case that an ACK is being transmitted on the HS-SICH, the UE shall apply a power offset to the transmit power
`of the entire HS-SICH. This power offset shall be signalled by higher layers.

`
`4.2.2.3.1
`
`Gain Factors
`
`Two or more transport channels may be multiplexed onto a CCTrCH as described in [9]. These transport channels
`undergo rate matching which involves repetition or puncturing. This rate matching affects the transmit power required
`to obtain a particular Eb/N0. Thus, the transmission power of the CCTrCH shall be weighted by a gain factor .
`
`There are two ways of controlling the gain factors for different TFC’s within a CCTrCH transmitted in a radio frame:
`
`-  is signalled for the TFC, or
`
`-  is computed for the TFC, based upon the signalled settings for a reference TFC.
`
`Combinations of the two above methods may be used to associate  values to all TFC’s in the TFCS for a CCTrCH.
`The two methods are described in sections 4.2.2.3.1.1 and 4.2.2.3.1.2 respectively. Several reference TFC’s for several
`different CCTrCH’s may be signalled from higher layers.
`
`The weight and gain factors may vary on a radio frame basis depending upon the current SF and TFC used. The setting
`of weight and gain factors is independent of any other form of power control. That means that the transmit power P UL is
`calculated according to the formula given in [15] and then the weight and gain factors are applied on top of that, cf.
`[10].
`
`4.2.2.3.1.1
`
`Signalled Gain Factors
`
`When the gain factor j is signalled by higher layers for a certain TFC, the signalled values are used directly for
`weighting DPCH or PUSCH within a CCTrCH. Exact values are given in [10].
`
`4.2.2.3.1.2
`
`Computed Gain Factors
`
`The gain factorj may also be computed for certain TFCs, based on the signalled settings for a reference TFC:
`
`Let ref denote the signalled gain factor for the reference TFC. Further, let j denote the gain factor used for the j-th
`TFC.
`
`Define the variable:
`
`
`
`where RMi is the semi-static rate matching attribute for transport channel i, Ni is the number of bits output from the
`radio frame segmentation block for transport channel i and the sum is taken over all the transport channels i in the
`reference TFC.
`
`Similarly, define the variable
`
`
`
`where the sum is taken over all the transport channels i in the j-th TFC.
`
`Moreover, define the variable
`
`
`
`where SFi is the spreading f
