Description
Technical field
The present invention relates to technical field of mobile terminals more particularly to a kind of information sending diversity applied to uplink closed loop
Processing method and network element.
Background technology
Multi-antenna technology using more antennas in transmitting terminal and (or) receiving terminal by realizing higher power system capacity, more
Wide MPS process and better services quality.More antennas of transmitting terminal and (or) receiving terminal can both be used for realizing transmission
Or it receives diversity and can also be used to realize spatial reuse.Wherein, it is a kind of to send at least two in transmitting terminal and contain to send diversity technique
There is the anti-fading technology of the wireless communication field of the signal of identical information.The signal of these carrying identical informations derives from least 2
A mutually independent signal source.It sends diversity technique and emits the structure of signal sample and statistical property and its shared nothing according to it
The difference of line resource can be divided into space, frequency, 3 big fundamental type of time, can also be combineding with each other for this 3 type.
So-called space diversity refers to the difference using different launch sites (space) position, and signal after undergoing channel when reaching receiving terminal
Irrelevance in statistical property realizes anti-fading function.So-called frequency diversity refers to utilizing the letter positioned at different frequency range
Uncorrelated characteristic number after fading channel statistically, i.e. difference on different frequency range fading statistical characteristics, it is anti-ageing to realize
Fall the function of (frequency selectivity).Information to be sent can be modulated at respectively on the incoherent carrier wave of frequency and be carried out when realization
Transmitting.So-called time diversity refers to utilizing a randomly fading signal, (is more than transmission when the time interval of sample point is sufficiently large
Channel coherency time), the decline between sampling point is statistically orthogonal, that is, utilizes the difference in time fading rise statistical property
It is different to realize anti-time selective fading.Send what whether diversity technique needed to need to transmitting terminal feedback diversity according to receiving terminal
Parameter is divided into open loop and sends diversity mode and closed-loop diversity transmitting mode.Open loop is sent under diversity mode, and receiving terminal is not to transmission
End feedback it is any it is additional with emit relevant information, transmitting terminal can voluntarily use corresponding coding techniques (such as simply
Space-Time encodes) it completes to send diversity.Under closed-loop diversity transmitting mode, receiving terminal needs to feed back to transmitting terminal using feedback channel
One with send the relevant parameter of diversity (such as send diversity needed for precoding vector, by precoding indicate information refer to
Show), transmitting terminal uses the feedback information to complete to send diversity after the receipt.
In 3GPP Release 10, High Speed Uplink Packet access (High Speed Uplink Packet
Access, abbreviation HSUPA) the uplink open loop of system subscriber terminal sends diversity and has been completed the formulation (TR25.863) of standard,
The related content that closed-loop diversity transmitting is currently discussed, introduces and indicates (Transmitted Precoding by transmission precoding
Indication, abbreviation TPI).The channel architecture that current industry sends diversity in uplink closed loop is reached common understanding, and a uplink is increased
Channel, i.e., auxiliary Dedicated Physical Control Channel (S-DPCCH) upload auxiliary pilot value to network side, and network can utilize and receive guidance
Pilot value in frequency value and Dedicated 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. F-PCICH scores precoding indicates
Channel, 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 applications TPI weighting.For receiving
TPI, terminal will measure its reliability, if terminal is estimated in previous 3 or 240 time slots on F-TPICH on service link
The domains TPI, at least one TPI, which meets code and disclosure satisfy that, certain measures threshold value Qtpi, wherein QtpiIt is to be determined by dependence test
, 3 time slots or 240 time slots are to determine that terminal just receives TPI orders using this by high level, are both used in this domain TPI
Precoding values carry out beam forming operation, complete uplink closed loop and send diversity.
The support that uplink closed loop sends the configuration of diversity terrestrial interface has been increased in 3GPP agreements at present.But for clothes
The processing method for the configuration that the scene uplink closed loop of business zone migration sends diversity does not have solution.
