Disambiguation of random access response for random access support on supplemental uplink
Abstract:
Certain aspects of the present disclosure relate to communication systems, and more particularly, to random access channel (RACH) procedures in deployments where a RACH transmission may be sent on different UL carriers. An exemplary method performed by a base station includes receiving a random access (RA) preamble on a first component carrier (CC) of a plurality of CCs including at least one uplink (UL) CC and at least one supplemental uplink (SUL) CC and transmitting a response to the RA preamble, wherein the response indicates the first CC.
