摘要：
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sounding reference signal (SRS) management for a line-of-sight multiple-input multiple-output (LSM) mode. A receiving device may receive a configuration of a persistent or semi-persistent SRS resource set that configures a first number of SRS ports for a full spatial sounding mode. The receiving device may transmit a SRS on a partial sounding resource subset of the SRS resource set, the partial sounding resource subset corresponding to a partial sounding LSM mode. A transmitting device such as a base station may performing phase ramp interpolation for the partial sounding LSM mode to estimate a LSM channel between the base station and the first receiving device.
