Description
Technical field
The present invention relates to communication technical field, relate in particular to collocation method, system and network controller that a kind of uplink closed loop sends diversity.
Background technology
Multi-antenna technology is by realizing that with many antennas higher power system capacity, wider residential quarter cover and better quality of service at transmitting terminal and/or receiving terminal.Many antennas of transmitting terminal (or receiving terminal) both can be used for realize sending or receive diversity, also can be used for the implementation space multiplexing.Send diversity technique and be a kind of anti-fading technology that sends the wireless communication field of at least 2 signals that contain identical information at transmitting terminal.The signal of these carrying identical information derives from least 2 separate signal sources.
Send diversity technique according to the structure of its sample value that transmits and statistical property with and shared Radio Resource different, can be divided into space, frequency, large fundamental type of times three, also can be mutually combining of this three types.So-called space diversity refers to utilize the difference of position, different launch sites (space), and the irrelevance when signal reaches receiving terminal behind the experience channel on statistical property realizes the anti fading function.So-called frequency diversity refer to utilize be positioned at different frequency range signal after fading channel in statistical uncorrelated characteristic, i.e. difference on the different frequency range fading statistical characteristics realizes the function of anti-fading (frequency selectivity).Information to be sent can be modulated at respectively on the incoherent carrier wave of frequency during realization and launch.So-called time diversity refers to utilize a randomly fading signal, when time interval of sampling point is enough large (greater than transmission channel coherence time), decline between sampling point is incoherent mutually in statistics, namely utilizes the difference on the time fading rise statistical property to realize anti-time selective fading.
Whether send diversity technique needs to be divided into open loop transmit diversity pattern and closed-loop diversity transmitting mode to the parameter of transmitting terminal feedback diversity needs according to receiving terminal.Under the open loop transmit diversity pattern, receiving terminal is not to any extra information relevant with emission of transmitting terminal feedback, and transmitting terminal can use corresponding coding techniques (for example simple Space-Time coding) to finish the transmission diversity voluntarily.Under the closed-loop diversity transmitting mode, receiving terminal need to use feedback channel to feed back to parameter relevant with sending diversity of transmitting terminal and (for example send the required precoding vector of diversity, by the indication of precoding indication information), transmitting terminal uses this feedback information to finish the transmission diversity after reception.
In 3GPP Release 10, HSUPA (High Speed Uplink Packet Access, the High Speed Uplink Packet access) the up open loop transmit diversity of system subscriber terminal has been finished the formulation (TR25.863) of standard, the related content of closed-loop diversity transmitting is being discussed at present, introducing is transmitted precoding indication (Transmitted Pre-coding Indication is called for short TPI).
Current industry is reached common understanding at the channel architecture that uplink closed loop sends diversity, as shown in Figure 1, increase a up channel, be auxiliary Dedicated Physical Control Channel S-DPCCH, upload auxiliary pilot value to network side, the weak situation that network side can utilize the auxiliary pilot value that receives and the pilot value in the special used for physical control channel DPCCH to recognize channel path is used for estimation TPI value; Newly increase a down channel, be similar to fractional dedicated physical channel F-DPCH, i.e. mark precoding indicating channel F-PCICH is used for transmitting the code value that prelists of up transmit diversity to terminal.TPI indication renewal rate is 3 time slots.Receive 512 spreading rates behind the TPI, terminal is used the precoding weighting of TPI indicating at first DPCCH boundary of time slot.For the TPI that receives, terminal will be measured its reliability, if terminal is formerly estimated from the TPI territory on the F-PCICH on the service link in 3 or 240 time slots, have at least a TPI to meet code and can satisfy certain measurement threshold value Qtpi, wherein Qtpi is determined by dependence test, 3 time slots or 240 time slots are determined by high level, terminal is just utilized the TPI order that receives, use the code value that prelists in this TPI territory to carry out wave beam forming (beamforming) computing, finish uplink closed loop and send diversity.
In sum, have following technical problem in the prior art: the configuration of uplink closed loop transmission diversity terrestrial interface has increased the support of network controller configuration UE from Serving cell reception TPI in the 3GPP agreement at present, but network enabled controller configuration UE receives TPI from service link collection residential quarter.
