TRANSMISSION OF SOUNDING REFERENCE SIGNALS FROM A USER EQUIPMENT IN RESPONSE TO MULTIPLE REQUESTS

摘要

Methods and apparatus are provided for a User Equipment (UE) to transmit a Sounding Reference Signal (SRS). Afirst Downlink Control Information (DCI) format with an aperiodic SRS request field indicating aperiodicSRS transmission with first values for aperiodic SRS transmission parameters, is received. A second DCI format with an aperiodic SRS request field indicating aperiodic SRS transmission with second values for the aperiodic SRS transmission parameters, is received. The first values for the aperiodic SRS transmission parameters are compared with the second values for the aperiodic SRS transmission parameters. An aperiodic SRS is transmitted when the first values are identical to the second values. Transmission of the aperiodic SRS is suspended when the first values are not identical to the second values.
