Description
Technical field
The present invention relates to wireless communication technology field, control command word transmission method, device and base station when relating in particular to a kind of up discontinuous emission (DTX, Discontinuous Transmission).
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 that the time-division the is synchronous) system.In up closed-loop control mechanism, subscriber equipment (UE) is according to periodically adjusting launch time and transmitting power from the entrained control command of base station feedback link.
For uplink synchronous, after the base station receives signal from subscriber equipment, determine the emission lead whether needs increase or reduce subscriber equipment, and produce the corresponding synchronous control command according to position measurements to upward signal.The base station passes to subscriber equipment with synchronous control command by descending feedback channel, and subscriber equipment is adjusted up launch time after receiving synchronous control command.
For uplink power control, after the base station receives signal from subscriber equipment, according to SIR (Signal to Interference Ratio to upward signal, signal-to-jamming ratio) whether the measured value decision needs to increase or reduce the transmitting power of subscriber equipment, and produces corresponding power control command.The base station passes to subscriber equipment with power control command by descending feedback channel, and subscriber equipment is adjusted uplink transmission power after receiving power control command.
For the TD-SCDMA system, if the high level of base station or subscriber equipment is at Transmission Time Interval (TTI, Transmission Time Interval) there are not data to offer coded combination transmission channel (CCTrCH in, Coded Composite Transport Channel) time, base station and subscriber equipment can be that unit implements discontinuous emission (DTX) with CCTrCH.When DTX acts on certain CCTrCH, this CCTrCH stops conventional data transmission, change into certain cycle emission special burst (SBs, Special Bursts), stop all the other temporal signal emissions simultaneously, the up SB emission cycle is called SBGP (special burst generation period, special burst generates the cycle), the descending SB emission cycle is called SBSP (special burst scheduling period, special burst dispatching cycle).The enforcement of discontinuous emission eats dishes without rice or wine to disturb, save equipment energy consumption to minimizing and implement between the frequency of wireless system/and switch between system positive role is arranged.
For the TD-SCDMA system, when DTX acts on up CCTrCH, for up closed loop synchronously and the power control meeting exert an influence.Because up CCTrCH is in discontinuous emitting state, the 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.
At present the base station is when up DTX, the control command word issued two kinds of methods:
A kind of method is, the base station produces the control command word according to SB, and in all the other times in SBGP cycle, repeat to send this command word, in this case, if there is subscriber equipment to respond these command words always, then can appear at SBGP wireless frame period, the situation that subscriber equipment is controlled by certain method always (continues to increase or reduces such as power, continue forward synchronously or backward), this is that the control result that sees is not wished in the base station.
Another kind method is, the base station produces the control command word according to SB and issues, in all the other times in SBGP cycle, issue and make the unregulated control command word of subscriber equipment, in this case, if subscriber equipment is arranged because the reason of time delay does not receive the control command word that produces according to SB, then the effect of SB maintenance link still loses, and also is that the control result that sees is not wished in the base station.
