Description
The cross reference of related application
This application claims the priority for the 61/640th, No. 204 U.S. Provisional Application submitted on April 30th, 2012, its
Disclosure is fully incorporated in this by reference.
Technical field
Embodiments of the present invention are usually related to ascending multi-code road in communication system, more particularly to double receipts single-shot systems and sent out
Send control method, device and the corresponding computer program product of power.
Background technology
At present, in TD SDMA (TD-SCDMA) system, the control method of uplink transmission power is usually
For the user situation that at most two code channels of occupancy and uplink synchronous sequence are only sent in uplink synchronous time slot.
Defined in 3GPP TS25.223V11.0.0 (2012-09) up more in the TD-SCDMA system of single-shot list receipts
Individual coded composite transport channel (CCTrCH) (i.e. more code channels) (now supports most 2 code channels) when same time slot is sent together
The distribution of transmit power.
Fig. 1 shows the principle of the combination of two different physical uplink link channels in a time slot.To be combined is up
DPCH (UL DPCH) has been subjected to spread, therefore is complex valued sequence herein.
First, each CCTrCH code channel power is obtained according to up open Loop Power control, wherein each CCTrCH code channel
Power is independently controllable by system.Open Loop Power control is in 3GPP TS25.105：“UTRA(BS)TDD；Radio
Transmission and Reception " are described.Into after close-loop power control, each CCTrCH code channel power is initial
Open loop power value plus after each transmit power control (TPC) adjusted value.TPC adjusted values are in 3GPP TS25.221
There are specific descriptions.
Then, each CCTrCH code channel power is multiplied by power settings (PowerSetting) (namely power distribution respectively
Than) to be adjusted.Then, each CCTrCH passes through weight factor γiIt is weighted respectively, plural conjunction then is carried out to signal
And.
Combining all CCTrCH and then gain factor β with the transformat combination (TFC) depending on realityjIt is multiplied,
So as to obtain the transmit power of the time slot.Signal after combination is sent to next stage processing, such as modulating stage.
In the schematic flow shown in Fig. 1, γi=10log10 (SF), wherein SF are spreading factor；
PowerSetting is the adjusted value of the baseband signal amplitude of each code channel of the time slot, and it keeps and inphase quadrature (IQ) data bit
Capacity matching.
Make specific expansion to the regulation in Fig. 1, the calculating of the PowerSetting values of two code channels in Fig. 1 can be obtained
Journey.For simplicity, herein to βjIt is added without discussion, βjIt is gain factor.It is defined as follows parameter：
TxAmpNorm：Each code channel j PowerSettingj quadratic sum, the value represent a time slot baseband signal amplitude
Quadratic sum, it is a constant constant；
TxGainLevel：The transmit power that the RF lateral roots of the time slot are set according to the time slot power；
Pj：Code channel j open loop transmit power；
DeltaPj：Code channel j TPC adjusted values；
SFj：Code channel j spreading factor SF.
Join Pj+10*log10 (SFj)+DeltaPj as the input for calculating PowerSettingj and TxGainLevel
Number, wherein originating originally when sending, DeltaPj=0；Suffix j=1,2 represent code channel 1 and code channel 2 respectively.It can then obtain：
PowerSetting12+PowerSetting22=TxAmpNorm2 (3)
The PowerSetting values of each code channel and the transmit power of the time slot can be calculated according to formula (1)-(3)
TxGainLeve1, following (4)-(6) formula：
, will according to the calculating process of above-mentioned formula (4)-(6)Value be set to A, can establish it is a from
The numerical tabular that line obtains, this pattern (4)-(6) can be reduced to：
TxGainLevel=P2+DeltaP2+10 × log10(1+A) (9)
For digital signal processor (DSP) realization, need altogether With 10 × log10
(1+A) three parts of tables.
Therefore, the dual track transmit power calculation process that can be simplified：
(a) according to the code channel power calculation difference power P1+DeltaP1-P2-DeltaP2 of two code channels；And
(b) above-mentioned three parts of tables are searched and are calculated by formula (7)-(9), can obtain each code channel PowerSetting values and
TxGainLevel values.
Fig. 2 shows the transmit power of the dual track of the simplification and the calculation process of PowerSetting values.
In the dual carrier system of double receipts single-shots, up-link needs to support 3-4 code channel to send in same time slot simultaneously.
According to the calculating process of the code channel of dual track/two, the calculating process of more code channels similarly can obtain.
Specifically, by taking 4 code channels as an example, code channel 3 and code are represented respectively with SF3, P3, DeltaP3, SF4, P4, DeltaP4
SF, TPC adjusted value and open loop power in road 4, PowerSetting values be expressed as PowerSetting3 and
PowerSetting4.Equation below can be obtained：
PowerSetting12+PowerSetting22+PowerSetting32+PowerSetting42=TxAmpNorm2 (14)
According to calculating process similar to the above, PowerSetting values and the transmission of the time slot of each code channel can be obtained
Power.It is as a result as follows by taking PowerSetting4 as an example：
PowerSetting1, PowerSetting2, PowerSetting3 and TxGainLevel can also be obtained similarly
Arrive.
But, can see from formula (15), now if by the numerical value simple flow of above-mentioned dual track, it is necessary to dependent on three
The different value of individual code channel difference.As such, it is desirable to leave the numerical tabular come offline by 8 times when being dual track, DSP is considerably increased
Memory space expense.Similarly, 4 times of memory space is also required in the case of three code channels are sent.So in double receipts single-shots
Dual carrier system in, the transmit power of code channel more than this part calculate numerical tabular will need to expand as 13 times.
Therefore, it is necessary to which a kind of method simplifies the calculating of more code channel transmit powers.
