Description

The control method and system of transmitting diversity

Technical field

The present invention relates to the communications field, in particular to the control method and system of a kind of transmitting diversity.

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.During implementation, more antennas of transmitting terminal and (or) receiving terminal can both be used for Realize that sending or receive diversity may also be used for realizing spatial reuse.

It is a kind of wireless communication field that the signal that at least two contains identical information is sent in transmitting terminal to send diversity technique Anti-fading technology.The signal of these carrying identical informations is from the separate signal source of at least two.Send diversity technique According to the structure and statistical property and the difference of its shared Radio Resource of its transmission signal sample value, space, frequency can be divided into Any one or more in rate, 3 big fundamental type of time or this 3 type be combined with each other, now to three big basic classes Type is described in detail.

So-called space diversity refers to after channel is undergone reach using the difference of different launch sites (space) position, signal Irrelevance during receiving terminal in statistical property, realize anti-fading function.So-called frequency diversity refers to utilize positioned at difference Uncorrelated characteristic of the signal of frequency range after fading channel statistically, i.e. difference on different frequency range fading statistical characteristics, come Realize the function of anti-fading (frequency selectivity).Information to be sent can be modulated to the incoherent load of frequency respectively when realizing Launched on ripple.So-called time diversity refers to utilize a randomly fading signal, when the time interval of sample point is sufficiently large (being more than transmission channel coherence time), the decline between sampling point are statistically orthogonal, that is, utilize time fading rise statistics Difference in characteristic realizes anti-time selective fading.

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.In the case where open loop sends diversity mode, 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 Send diversity.Under closed-loop diversity transmitting mode, receiving terminal needs to use feedback channel to feed back to transmitting terminal one and transmission point Collect related parameter (such as precoding vector needed for transmission diversity, indicated by precoding configured information), transmitting terminal is connecing After receipts transmission diversity is completed using the feedback information.
