Description
Technical field
The present invention relates to wireless communication technology field, control command word transmission method when particularly relating to a kind of up discontinuous transmitting (DTX, Discontinuous Transmission), device and base station.
Background technology
The uplink synchronous of closed loop and uplink power control technology are the basic technologies in TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access, the code division multiple access of time division synchronous) system.In uplink closed loop controlling mechanism, subscriber equipment (UE) is according to periodically adjusting launch time and transmitting power from the control command entrained by base station feedback link.
For uplink synchronous, after base station receives the signal from subscriber equipment, according to the transmitting lead determined the position measurements of upward signal the need of increasing or reduce subscriber equipment, and produce corresponding synchronous control command.Synchronous control command is passed to subscriber equipment by descending feedback channel by base station, and subscriber equipment adjusts uplink transmission time after receiving synchronous control command.
For uplink power control, after base station receives the signal from subscriber equipment, according to SIR (the Signal to Interference Ratio to upward signal, signal-to-jamming ratio) measured value determines the need of increasing or reducing the transmitting power of subscriber equipment, and produces corresponding power control command.Power control command is passed to subscriber equipment by descending feedback channel by base station, and subscriber equipment adjusts uplink transmission power after receiving power control command.
For TD-SCDMA system, if the high level of base station or subscriber equipment is at Transmission Time Interval (TTI, Transmission Time Interval) in do not have data to be supplied to Coded Combined Transport Channel (CCTrCH, Coded Composite Transport Channel) time, base station and subscriber equipment can implement discontinuous transmitting (DTX) in units of CCTrCH.When DTX acts on certain CCTrCH, this CCTrCH stops conventional data to launch, change into certain periodic emission special burst (SBs, Special Bursts), stop all the other temporal signals to launch simultaneously, the up SB transmitting cycle is called SBGP (special burst generation period, special burst generating period), descending SB launches the cycle and is called SBSP (special burst scheduling period, special burst dispatching cycle).The enforcement of discontinuous transmitting eats dishes without rice or wine to disturb to reducing, save equipment energy consumption and implement wireless system frequency between/intersystem handover has positive role.
For TD-SCDMA system, when DTX acts on up CCTrCH, can have an impact for up closed-loop synchronization and power control.Because up CCTrCH is in discontinuous emitting state, base station can only receive the SBs of burst with the cycle of SBGP radio frames, and does not receive signal in all the other times of a whole SBGP wireless frame period.
Current base station when up DTX, control command word issued two kinds of methods:
One method is, base station produces control command word according to SB, and repeat to send this command word in all the other times in SBGP cycle, in this case, if there is subscriber equipment to respond these command words always, then appear in SBGP wireless frame period, (such as power continues to increase or reduces the situation that subscriber equipment is controlled by certain method always, synchronous to continue forward or backward), this is the control result that base station does not wish to see.
Another kind method is, base station produces control command word according to SB and issues, issue in all the other times in SBGP cycle and make the unregulated control command word of subscriber equipment, in this case, if have subscriber equipment because the reason of time delay does not receive the control command word produced according to SB, then the effect of SB maintenance link still loses, and is also the control result that base station does not wish to see.
