Title:
USER EQUIPMENTS, BASE STATIONS, AND METHODS FOR MULTI-BEAM SRS TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2022/210511
Kind Code:
A1
Abstract:
A user equipment (UE) is described. The UE includes reception circuitry configured to receive downlink control information (DCI) indicating aperiodic sounding reference signal (SRS) transmission without an uplink shared channel (UL-SCH) and without a channel state information (CSI) request. The UE also includes transmission circuitry configured to transmit sounding reference signals. A cyclic redundancy check (CRC) bit for a first DCI indicating aperiodic SRS transmission for scheduling UL-SCH and/or triggering a CSI report is scrambled by a first radio network temporary identifier (RNTI). A CRC bit for the first DCI indicating aperiodic SRS transmission without an UL-SCH and without a CSI request is scrambled by a second RNTI.
