Fig. 1 is illustrated including base station（BS）1 and mobile station（MS）2 radio communications system 100.Can via channel, Specially multipath channel transmits radiocommunication signals from base station 1 to mobile station 2 and vice versa.Signal based on reception, Mobile station 2 can determine feedback information and can transmit this information to base station 1.Base station 1 can be with feedback information to adjust Its whole signal transmission.Such as feedback information may be used to determine weight（Or weighted factor）, these weights（Or weighting because Son）The phase relation or phase difference being determined between multiple transmitting antennas of base station 1.Description from mobile station 2 Transmission to the feedback information of base station 1 is properly termed as backfeed loop.
Before and during communication of the initialization between base station 1 and mobile station 2, backfeed loop can be opened, because example One of mobile station 2 can such as be turned off（Or should）Transmitter, i.e. not from mobile station 2 to the transmitting feedback information of base station 1.It is such Initialization period is properly termed as " initial synchronisation " or " in initial synchronisation（In-Sync）”.The transmitter for turning off mobile station 2 can be with It is considered as protection, because mobile station 2 may not receive signaling and/or order to ensure to move with quality good enough from base station 1 The appropriate operation of the transmitter of platform 2.During this initialization period, base station 1 can adjust its letter using predetermined set Number transmission because feedback-less information can use., can be with closed feedback loop if meeting some first predetermined condition, such as can So that the transmission of the transmitter of mobile station 2 and feedback information is respectively started.Then downlink can have been carried out initial synchronisation shape State.In a similar manner, the transmission of feedback information can be interrupted, such as because of the communication period between base station 1 and mobile station 2 such as Fruit meets that the second predetermined condition can then stop the transmitter of mobile station 2.Such stage characterized by opening backfeed loop It is properly termed as " Tx shut-offs（Tx-off）”.In general, the state for wherein activating transmitter of mobile station 2 is properly termed as " synchronously In " state.
Fig. 2 diagrams method 200 disclosed in.Such as method 200 can be by the reception that includes in Fig. 1 mobile station 2 Device circuit performs.At 3, via Channel Received Signal.At 4, the signal based on reception determines feedback information.At 5, it is based on Feedback information determines the quality of quality indicator, the wherein signal that quality indicator instruction receives.At 6, if quality indicates Symbol meets that predetermined condition then starts or recovered the transmission of feedback information.
Pay attention to according to method 200, it may be determined that feedback information and quality indicator, even if not yet closed feedback loop.Cause This, if closed feedback loop determine can based on if actual closed feedback loop by the value of caused quality indicator （And therefore it is based on feedback information）.That is, closed feedback loop may rely on the value of the calculating of quality indicator, but It is not rely in the value of the actual measurement of quality indicator.
Referring still to Fig. 2, the signal received at 3 can be received on downlink direction.Therefore, it is possible in uplink The feedback information that transmission determines at 4 on the direction of road.It should be understood that method 200 can be extended to wherein from more than one base station （Or radio plot）, such as up to six base station received signals scene.For each base station, it may be determined that respective quality Designator.But in one example, only same respective feedback information can be sent from mobile station 2 to all base stations.This can Be for 3GPP CLTD operation situation.Alternatively, for each base station, it may be determined that respective feedback information and corresponding matter Amount instruction accords with.Similarly, can since mobile station 2 is to corresponding base station or recover respective feedback information transmission.Pay attention to pair In each base station, indivedual or unique first and second predetermined condition can be defined.Alternatively, according to the first He of action 6 Second predetermined condition can be identical for each base station in the base station of consideration.Pay attention to for each base station, can be with Define the indivedual predetermined sets transmitted for adjusting its signal.Alternatively, can be with for adjusting the predetermined set of signal transmission It is identical for each base station in the base station of consideration.
Feedback information can include Closed-Loop Transmit Diversity（CLTD）Feedback information.In CTLD, mobile station 2 can provide can With the feedback phase information by time slot of the channel profile based on reception.It can determine that feedback information to maximize in movement The SINR received at platform 2.Such as can be in feedback information（FBI）Feedback signalling message is transmitted in field（FSM）Position, can be upper Downlink dedicated physical control channel（DPCCH）Include the FBI fields.It is it is noted that true with specific reference to above-mentioned 3GPP standards Fixed, processing and transmitting feedback information.
Feedback information can correspond to or can include the information of the phase adjustment on one or more antenna.Example The signal received such as at 3 can be via the first antenna and the second antenna transmission of base station 1.In this case, feedback letter Breath can determine phase adjustment of second antenna relative to first antenna.Understand that mobile station 2 can also be from the more than two of base station 1 Antenna reception signal so that feedback information can include the information on multiple phase adjustments between the antenna of consideration.Note Meaning can be with specific reference to phase adjustment as the definition of above-mentioned 3GPP standards, determination and transmission.
The first predetermined condition at 6 can include quality indicator more than the first predetermined threshold.Such as quality indicator The ratio between noise for example can be added with signal and interference（SINR）Or the form of any other appropriate amount indicates special physics control Channel processed（DPCCH）, DPCH（DPCH）Or fraction DPCH（F-DPCH）Quality.If the quality of estimation exceedes Predetermined first threshold, then it can start or recover the transmission of feedback information.Similarly, if met second predetermined at 6 Condition, for example, if the quality of estimation is down to below predetermined Second Threshold, then it can interrupt or stop the transmission of feedback information. It is noted that predetermined condition and correlation threshold according to as specifying above-mentioned 3GPP standards.
First predetermined condition can include quality indicator and exceed predetermined first threshold persistently predetermined very first time interval.The Two predetermined conditions, which can be down to including quality indicator below predetermined Second Threshold, persistently makes a reservation for the second time interval.It is such as predetermined Each time interval in first and second time intervals can correspond to multiple frames, and a frame has 10 ms length.Specifically For, about 160 ms length can be had by making a reservation for the first and second time intervals.Equal duration can be divided the frame into 15 time slots.It is noted that each time slot renewal feedback information.
It can determine that feedback information causes the value of maximum quality designator.Such as feedback information can include in base The information of phase adjustment between the antenna stood, and quality indicator can be DPCH SINR.Then can determine to feed back Information causes phase adjustment to produce SINR maximum.
Quality indicator can be based on the signal of reception power and noise power.For example, quality indicator can correspond to In or can include receive signal signal to noise ratio（SNR）, SINR and error rate estimation at least one of.
Quality indicator can be based on transmitting power control（TPC）The quality of order, the transmitting power control（TPC）Order The up-link power for controlling mobile station can be used for by the base station being related to.TPC command as being embedded in DPCH. The transimission power of TPC command can be differently configured from the transimission power of the frequency pilot sign for the estimation that can be used for SINR and be different from The transimission power of DPCH real data symbol.Gained power excursion, i.e. these analog values can be transmitted to mobile station signal Between difference.Mobile station and then can be it is determined that considering power excursion during quality indicator.
Method 200 can also include the channel estimation for determining the multipath channel from base station to mobile station, wherein feedback information Based on channel estimation.Based on feedback information, therefore the transmission of base station can be adjusted according to present channel property.
Dedicated channel, such as DPCH channels can be included via the physical channel of its reception signal so that quality indicator It may rely on the channel estimation obtained from dedicated channel.Such as quality indicator can correspond to or can include be based on from The SINR that the channel coefficients of DPCH estimations and possible other amounts calculate.Similarly, via the physical channel of its reception signal Pilot channel, such as CPICH can be included so that quality indicator can also depend on the channel obtained from pilot channel to estimate Meter.Quality indicator can also depend on the channel estimation obtained from both special and pilot channels.
Whether the value that method 200 can also include detection channel indicator is down to below predetermined Second Threshold and if matter Amount instruction symbol, which is down to below predetermined Second Threshold, continues the transmitter that some time interval then turns off mobile station.Notice that Tx turns off rank Section can continue only short time interval so that the interruption of feedback transmission can not detected even by base station 1.
Before closed feedback loop, base station 1 and the additional base station being related to can use predetermined and constant initial power Weight to adjust the phase relation between the transmission antenna of base station 1 and the additional base station being related to respectively.Such initial power The feedback information that may deviate from the feedback information estimated according to Fig. 2 action 4 is can correspond to again.It is such inclined in order to consider From the difference that method 200 can also be included between feedback information and feedback on reservation information based on determination determines correction factor.Quality Designator may rely on the correction factor of determination.
Correction factor can be used for by estimating channel, such as DPCH come the multiple rotation of channel coefficients that determines （complex rotation）.
Method 200 can be performed in initial synchronisation and/or during Tx off-phases.In both cases, it is not closed anti- It is fed back to road.But in initial synchronisation in the case of the stage, the known predetermined set that mobile station 2 can use base station 1 is used for Data demodulate rather than the feedback information to being determined according to action 4 performs antenna verification.It is mobile in the case of Tx off-phases Platform 2 can perform antenna verification to the feedback information determined according to action 4.
The transmission that method 200 is additionally may included in feedback information has begun to or has been resumed（Such as see that Fig. 2's is dynamic Make 6）Continue to determine feedback information afterwards.Due to closed feedback loop, so method 200 can also be including anti-to what is continuously determined Feedforward information performs antenna verification.In another method and step, quality indicator can be determined based on the feedback information of checking.
Method 200 can also include the feedback information based on checking and perform high specific combination（MRC）.Specifically, can be with MRC schemes are applied into DPCH data to allow to obtain the DCPH data demodulated, transmitting power control（TPC）And transformat Combined indication character（TFCI）Symbol.
