TECHNIQUES FOR PERFORMING RANDOM ACCESS USING MULTIPLE BEAMS IN WIRELESS COMMUNICATIONS

Abstract:

Aspects described herein relate to determining multiple beams to use in transmitting messages in a random access procedure with one or more transmission/reception points (TRPs) of a cell, and transmitting, to the one or more TRPs of the cell, multiple instances of a first random access message based on the multiple beams, where each of the multiple instances of the first random access message include a preamble portion and a payload portion. In another aspect, a node receiving the multiple instances of the first random access message can determine multiple beams to use in transmitting messages in the random access procedure and can transmit with one or multiple TRPs, to the UE and in response to the first random access message, multiple instances of a second random access message based on the multiple beams.
