Document Type and Number:
WIPO Patent Application WO/2022/146102
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). Apparatuses and methods for random access procedures with multiple transmission reception points or cells in a wireless communication system. A method for performing RA procedures by a user equipment includes receiving a first configuration for RA. The method further includes initiating a first RA procedure with a first TRP based on the first configuration and initiating a second RA procedure with a second TRP prior to completion of the first RA procedure. A method for operating a base station includes transmitting a first configuration for RA corresponding to a first TRP and transmitting a second configuration for RA corresponding to a second TRP.
