Abstract: A beam indication (BI) mechanism is proposed to provide user equipment (UE) information of network (NW) beam(s) for later transmission. UE can then select its UE beam(s) for the later transmission based on the BI. In one embodiment, NW provides beam management configuration to UE via Radio Resource Control (RRC) signaling, and then provides beam indication index signaling to UE via MAC-CE or DCI. The beam management configuration comprises a mapping table between network beams and configured reference signal (RS) resources. The beam indication index signaling indicates one or more preferred beam pair links (BPLs). Upon triggering a beam management procedure by the network, UE is able to identify the beam management procedure and selects corresponding UE beam(s) based on the beam management configuration and the beam indication index signaling.
