Title:
BEAM INDICATION METHOD AND APPARATUS, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/041377
Kind Code:
A1
Abstract:
The present disclosure provides a beam indication method and apparatus, and a readable storage medium. The method comprises: receiving target information sent by a network side device, wherein the target information comprises beam indication information carried by a first reserved bit in a random access response (RAR), or the target information comprises beam indication information carried by a newly added field in the RAR; determining an optimal beam according to the target information; and according to the optimal beam, sending a message 3 physical uplink shared channel (Msg3 PUSCH), and/or sending a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for a message 4 physical downlink shared channel (Msg4 PDSCH). The transmission performance of a Msg3 PUSCH and/or a HARQ-ACK feedback for a Msg4 PDSCH message when multiple beams are used for transmitting a PRACH is improved.
