Abstract
Wireless communications systems and methods are provided for validating a physical uplink shared channel (PUSCH) occasion defined for 2-step random access channel (RACH) in case of collisions. For example, the user equipment (UE) may determine whether a collision occurs between the PUSCH occasion for the 2-step RACH and any RACH occasion assigned for either 2-step RACH or 4-step RACH after receiving the RACH configuration or updates from the network. The UE may then exclude the PUSCH occasion from the resource pool for 2-step RACH when a collision occurs.
