US 2023/0056962 A1 · BEAM SELECTION UNDER MULTIPLE TRANSMISSION POINTS

Abstract

Embodiments of the present disclosure relate to uplink control information for beam selection in the multiple transmission points. According to embodiments of the present disclosure, a network device determines the beam selection type based on the communication quality required for the network device and a further network device. The network device transmits the information of the beam selection type to a terminal device. The terminal device receives reference signals based on the beam selection type and performs a beam measurement based on the references signals. The terminal device selects a target transmitting beam from a plurality of transmitting beams of the further network device and transmits identities of the selected transmitting beam to the network device or the further network device. In this way, a proper transmitting beam can be selected based on the required communication quality. The latency is shortened and the transmission overhead is reduced.
