Abstract:
Apparatuses and methods for random access procedures with multiple transmission reception points or cells in a wireless communication system. A method for performing random access (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 transmission-reception point (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. The first TRP and the second TRP are associated with a same cell.
