Document Type and Number:
WIPO Patent Application WO/2023/019548
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure provide techniques for random access channel (RACH) configuration. Certain aspects are directed to a method for wireless communication by a user equipment (UE). The method generally includes: receiving, from a base station, a message comprising random access channel (RACH) configurations including a first RACH configuration indicating a first set of resources for reduced capability UEs supporting at least one first capability, a second RACH configuration indicating a second set of resources for coverage enhanced UEs supporting at least one second capability, and a third RACH configuration indicating a third set of resources for UEs supporting the at least one first capability and the at least one second capability; and transmitting a RACH message based on at least one of the RACH configurations.
