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.
