Description
Technical field
The present invention relates to moving communicating field, more particularly to a kind of uplink closed loop to send the renewal of diversity (CLTD) state of activation
Method and system.
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 receive diversity and may also be used for realizing spatial reuse.
Wherein, it is a kind of channel radio that at least two signals containing identical information are sent in transmitting terminal to send diversity technique
The anti-fading technology in letter field, the signal for carrying identical information derive from least two separate signal sources.Send diversity
The structure of its transmission signal sample value of technical basis and statistical property and the difference of its shared Radio Resource, can be divided into sky
Between, frequency, three big fundamental type of time or these three types be combined with each other；So-called space diversity refers to using not
The difference of same launch site (space) position, signal are uncorrelated in statistical property when reaching receiving terminal after undergoing channel
Property, realize anti-fading function；So-called frequency diversity refers to utilize the signal positioned at different frequency range counting after fading channel
On uncorrelated characteristic, i.e. difference on different frequency range fading statistical characteristics, to realize the function of anti-fading (frequency selectivity),
Information to be sent can be modulated at respectively on the incoherent carrier wave of frequency and be launched when realizing；So-called time diversity refers to
Using a randomly fading signal, (it is more than transmission channel coherence time) when the time interval of sample point is sufficiently large, between sampling point
Decline be statistically orthogonal, i.e., realize anti-time selectivity using the difference in time fading rise statistical property
Decline.
Send whether diversity technique needs to be divided into open loop transmission to the parameter that transmitting terminal feedback diversity needs according to receiving terminal
Diversity mode and closed-loop diversity transmitting mode.Open loop is sent under diversity mode, and receiving terminal is not any extra to transmitting terminal feedback
The information related 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 terminal needs to use feedback channel to feed back to transmitting terminal one with sending diversity phase
The parameter (such as precoding vector needed for transmission diversity, indicated by precoding configured information) of pass, transmitting terminal is after the receipt
Complete to send diversity using the feedback information.
In 3GPP Release 10, the up open loop of HSUPA system user terminal sends diversity and completed in standard
Formulation (TR25.863), currently discuss closed-loop diversity transmitting related content, introduce and indicated by transmission precoding
(Transmitted Precoding indication, TPI).The channel architecture that current industry sends diversity in uplink closed loop reaches
Into common recognition, confirm as shown in Figure 1, increase a up channel, i.e., auxiliary Dedicated Physical Control Channel (S-DPCCH), upload and teach
Frequency is worth to network side, network can using the pilot value received in auxiliary pilot value and Dedicated Physical Control Channel (DPCCH) come
The weak situation of channel path is solved, for estimating TPI values；A down channel is newly increased, is believed similar to Fractional Dedicated Physical
Road (F-DPCH), the i.e. precoding of F-PCICH fractions indicate channel, for transmitting the precoding values of up transmitting diversity to terminal.
TPI instruction renewal rates are 3 time slots.512 spreading rates after TPI are received, terminal is in first DPCCH boundary of time slot application
The precoding weighting indicated in TPI.For receiving TPI, terminal will measure its reliability, if terminal is at previous 3 or 240
TPI domain of the estimation on F-TPICH on service link in gap, at least one TPI meet code and disclosure satisfy that certain measurement door
Limit value Qtpi, wherein QtpiIt is to be determined by dependence test, 3 time slots or 240 time slots are to determine that terminal just applies this by high level
TPI orders are received, both carry out beamforming computings using precoding values in this TPI domain, complete uplink closed loop transmission point
Collection.
Terminal is configured with uplink closed loop and sends diversity, just there is five kinds of states of activation：
The channels such as DPCCH, DPDCH, E-DPCCH, E-DPDCH form a link and S-DPCCH channel links pass through
To sending on two antennas after beamforming, the state is referred to as uplink closed loop and sends diversity state of activation 1；
The channels such as DPCCH, DPDCH, E-DPCCH, E-DPDCH form a link and S-DPCCH channel links exist respectively
Sent on antenna 1 and antenna 2, the state is referred to as uplink closed loop and sends diversity state of activation 2；
The channels such as DPCCH, DPDCH, E-DPCCH, E-DPDCH form a link and S-DPCCH channel links exist respectively
Sent on antenna 2 and antenna 1, the state is referred to as uplink closed loop and sends diversity state of activation 3；
The channels such as DPCCH, DPDCH, E-DPCCH, E-DPDCH form a link and sent on antenna 1, S-DPCCH letters
Road is closed, and antenna 2 is closed, and state is referred to as uplink closed loop and sends diversity state of activation 4；
The channels such as DPCCH, DPDCH, E-DPCCH, E-DPDCH form a link and sent on antenna 2, S-DPCCH letters
