The invention discloses configuration method, system and network controllers that a kind of uplink closed loop sends diversity, for network controller when for UE and base station collocating uplink closed-loop diversity transmitting, instruction is that the serving cell from UE or the service link collection cell from UE send and receive TPI.The present invention realizes network controller and configures the support that UE receives TPI from service link collection cell, and perfect network controller sends the configuration of diversity to the uplink closed loop of base station.
Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of uplink closed loop send the configuration method of diversity, system and
Network controller.
Background technique
Multi-antenna technology is by realizing higher power system capacity, more using more antennas in transmitting terminal and/or receiving end
Wide MPS process and better services quality.More antennas of transmitting terminal (or receiving end) both can be used to realize transmission or
Diversity is received, can also be used to realize spatial reuse.Send diversity technique be it is a kind of transmitting terminal send at least two contain it is identical
The anti-fading technology of the wireless communication field of the signal of information.The signal of these carrying identical informations is mutual from least two
Independent signal source.
Send structure that diversity technique emits signal sample according to it and statistical property and radio resource shared by it not
Together, it can be divided into space, frequency, the big fundamental type of time three, be also possible to be combineding with each other for these three types.So-called space
Diversity refers to the difference using different launch sites (space) position, and signal is special in statistics when reaching receiving end after undergoing channel
Irrelevance in property, realizes anti-fading function.So-called frequency diversity refers to using the signal positioned at different frequency range through declining
Uncorrelated characteristic after channel statistically, i.e. difference on different frequency range fading statistical characteristics, to realize anti-fading (frequency choosing
Selecting property) function.Information to be sent can be modulated on the incoherent carrier wave of frequency respectively and be emitted when realization.It is so-called
Time diversity refers to using a randomly fading signal, (relevant greater than transmission channel when the time interval of sample point is sufficiently large
Time), the decline between sampling point be statistically it is irrelevant, i.e., realized using the difference in time fading rise statistical property
Anti- time selective fading.
It sends diversity technique and is sent according to whether receiving end needs the parameter needed to transmitting terminal feedback diversity to be divided into open loop
Diversity mode and closed-loop diversity transmitting mode.Open loop is sent under diversity mode, and receiving end is not fed back to transmitting terminal any additional
Information relevant to transmitting, transmitting terminal can voluntarily use corresponding coding techniques (such as simple Space-Time coding) to complete hair
Send diversity.Under closed-loop diversity transmitting mode, receiving end is needed to be fed back to transmitting terminal one using feedback channel and sends diversity phase
The parameter (such as precoding vector needed for sending diversity, indicate information instruction by precoding) of pass, transmitting terminal is after the receipt
It completes to send diversity using the feedback information.
In 3GPP Release 10, HSUPA (High Speed Uplink Packet Access, high speed uplink chain
Road grouping access) the uplink open loop of system subscriber terminal sends diversity and has been completed the formulation (TR25.863) of standard, at present just
In the related content that closed-loop diversity transmitting is discussed, introduces and (Transmitted Pre-coding is indicated by transmission precoding
Indication, abbreviation TPI).
Current industry is reached common understanding in the channel architecture that uplink closed loop sends diversity, as shown in Figure 1, increasing a uplink letter
Road, i.e., auxiliary Dedicated Physical Control Channel S-DPCCH upload auxiliary pilot value to network side, and network side can utilize the guidance received
Pilot value in frequency value and special used for physical control channel DPCCH recognizes the weak situation of channel path, for estimating TPI
Value；A down channel is newly increased, fractional dedicated physical channel F-DPCH is similar to, is i.e. score precoding indicates channel F-
PCICH, for transmitting the precoding values of uplink transmitting diversity to terminal.TPI indicates that renewal rate is 3 time slots.After receiving TPI
512 spreading rates, precoding that terminal indicates in first DPCCH boundary of time slot application TPI weighting.For what is received
TPI, terminal will measure its reliability, if terminal is estimated in previous 3 or 240 time slots on F-PCICH on service link
The domain TPI, at least one TPI, which meets code, can satisfy certain measurement threshold value Qtpi, and wherein Qtpi is determined by dependence test
Fixed, 3 time slots or 240 time slots are determined by high level, and terminal is just using the TPI order received, using prelisting in the domain TPI
Code value carries out wave beam forming (beamforming) operation, completes uplink closed loop and sends diversity.
In conclusion following technical problem exists in the prior art: uplink closed loop sends diversity in 3GPP agreement at present
Interface configuration in face has increased network controller and has configured the support of UE from serving cell reception TPI, but does not support network control
Device processed configures UE and receives TPI from service link collection cell.
