WIPO Patent Application WO/2024/060116

A1

This disclosure provides systems, methods, and devices for wireless communication that support PRACH repetition suing different beams. In a first aspect, a method of wireless communication includes determining that a first PRACH transmission occasion occurs during a first time period, determining that a second PRACH transmission occasion occurs during a second time period, transmitting a first PRACH transmission at the first PRACH transmission occasion using the first beam based on the determination that the first PRACH transmission occasion occurs during the first time period, and transmitting a second PRACH transmission at the second PRACH transmission occasion using the second beam based on the determination that the second PRACH transmission occasion occurs during the second time period, wherein the second PRACH transmission is a repetition of the first PRACH transmission.
