Description
Technical field
The present invention relates to communication technical field, particularly the method for measurement of a kind of signal and interference-to-noise ratio and device.
Background technology
CoMP(Coordinated Multi-Point transmission/reception, coordinated multipoint transmission) be LTE-A(Long Term Evolution advanced, follow-up Long Term Evolution) one of key technology, in order to expand the coverage of High Data Rate, the average throughput of elevator system, especially can improve the performance of Cell Edge User.For UL-CoMP(Uplink Coordinated Multi-Point transmission/reception, ascending multi-point collaboration transmission), can adopt the joint receiver system of a plurality of communities, as scheduling between base station coordinates to avoid interference or adopt associating reception, can obtain CoMP gain, and do not need the support of agreement, be easy to realize.
In UL-CoMP technology, based on ascending resource scheduling, MCS(Modulation Code Scheme, the demands such as adaptively selected, power control modulation coding mode), eNodeB(evolved NodeB, evolved base station) need to monitor the channel quality condition of up Whole frequency band, wherein important content is exactly the SINR(Signal to Interference and Noise Rate that measures channel, the ratio of signal and interference noise).SINR is the intensity and the interference receiving and the intensity ratio of noise signal of the useful signal that receives, and it has reflected the quality condition of channel.SINR is larger, represents that channel quality is better, and SINR is less, represents that channel quality is poorer.
In prior art, eNodeB is based on SRS(Sounding Reference Signal, detection reference signal) measure the SINR of channel.For UE(User Equipment, subscriber equipment), except sending DMRS(Demodulated Reference Signal, demodulated reference signal) give outside eNodeB, also can send SRS signal to eNodeB.SRS signal is the detection reference signal that UE sends in data transfer bandwidth, for channel being surveyed to (Sounding), to realize up frequency domain dispatching.When eNodeB receives after the SRS signal from UE, according to SRS signal, channel coefficient matrix H, local sequence, can obtain the interference noise on SRS signal, and calculate the Ruu(interference noise covariance of SRS signal) matrix, then according to this Ruu matrix and channel coefficient matrix H, calculate the balanced matrix W of SRS signal, then according to balanced matrix W and channel coefficient matrix H, calculate the SINR of channel.
In realizing process of the present invention, inventor finds that above-mentioned prior art at least has following shortcoming: the density of SRS signal is lower, not in each subframe, comprises SRS signal, as UE just sends SRS signal at set intervals; Therefore, can cause the Ruu matrix certainty of measurement of SRS signal lower, thereby cause the certainty of measurement of SINR on the low side.
