Title: FLEXIBLE SRS-BASED UPLINK BEAM MANAGEMENT
Abstract:
Systems, methods and instrumentalities are disclosed for flexible SRS-based UL beam management. UL beam management may be assisted, for example, by DL beam management. In an example, a WTRU may determine a UL Tx beam based on a DL Rx beam for full beam correspondence (BC), a WTRU may engage in beam adjustment with data transmission for partial BC and a WTRU may, e.g., otherwise, transmit an SRS for UL beam sweeping. BC may be determined, for example, by a WTRU or a TRP. WTRU may provide the assist information to facilitate TRP SRS configuration. Flexible UL beam management may be provided, for example, by flexible SRS configuration of WTRUs depending on configured beam management procedures. Intra-symbol UL beam sweeping may be provided with frequency and time separations. SRS power setting may be provided for UL beam management.
