CHANNEL MEASUREMENT FOR UPLINK TRANSMISSION

WIPO Patent Application WO/2019/192360

A1

A method for measuring a channel state information reference signal (CSI-RS) for non-codebook based uplink (UL) transmission. The method transmits information on a sounding reference signal (SRS) resource set for the non-codebook based UL transmission, information on a CSI-RS resource associated with the SRS resource set, information on CSI-RS measurement restriction, and a message that indicates a request for the SRS resource set transmission. The method receives the SRS resource set precoded based on precoding information determined for the SRS resource set using a measurement of the CSI-RS resource in accordance with the information on CSI-RS measurement restriction. The method measures the SRS resource set, and determines SRS resources within the SRS resource set to be used for UL transmission. The method transmits a DCI that indicates the SRS resources within the SRS resource set to be used for uplink transmission; and receives an uplink frame using the precoding information.
