METHOD AND APPARATUS FOR SUPPORTING TWO-STEP RANDOM ACCESS CHANNEL USAGE IN A WIRELESS COMMUNICATION SYSTEM

Abstract:

Methods and apparatuses related to a two-step RACH procedure are provided. Channel conditions can be estimated based on a UE PRACH transmission rather than the subsequent PUSCH transmission in the first part of the two-step RACH. A variable length gap can be provided between the PRACH preamble transmission and the PUSCH transmission. Other solutions are also provided.
