|1. (WO2018077119) WEIGHTED SOUNDING SIGNAL-BASED METHOD AND DEVICE FOR BEAMFORMING TRANSMISSION|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||WEIGHTED SOUNDING SIGNAL-BASED METHOD AND DEVICE FOR BEAMFORMING TRANSMISSION|
Disclosed is a weighted sounding signal-based method for beamforming transmission. The method comprises the following steps: when a user equipment determines that a beamforming (BF) weighted mode needs to be employed to transmit a sounding reference signal (SRS), the user equipment calculates, on the basis of downlink channel information, a BF weighted vector or matrix for SRS transmission; the user equipment weightedly transmits the SRS to a base station by means of the BF weighted vector or matrix. The present application has the advantages of increased SRS channel coverage range, increased channel estimation precision, and low complexity in BF weight calculation for base station downlink transmission.
