Claim of US Patent No. 10,512,104

1. A wireless transmit/receive unit (WTRU) comprising:a processor; and
a transceiver,
wherein the processor and the transceiver are configured to acquire a first random access configuration and a second random access configuration, wherein the first random access configuration and the second random access configuration are different,
wherein the processor and the transceiver are further configured to perform a first random access procedure using the first random access configuration using first physical resources and to perform a second random access procedure using the second random access configuration using second physical resources, wherein the first random access configuration is used for at least initial random access and the second random access configuration is used for at least timing adjustments, wherein the first physical resources are different physical resources than the second physical resources, and
wherein the processor and the transceiver are further configured to receive a first message for the first random access procedure and to receive a second message for the second random access procedure, wherein the first message is an aggregated response message including a plurality of first random access responses and the second message is an aggregated response message including a plurality of second random access responses.
