Abstract
A technique of performing a RACK procedure includes a framework for a two-step RACK in which a first message (MsgA) from the UE to the gNB has data carrying resources (i.e., PUSCH) is organized into a time-frequency array defined by a mapping to a plurality of preambles. Such a two-step RACK has less latency than the four-step RACK due to fewer signaling exchanges. Moreover, this two-step RACK also causes the UE to use less power due to a decreased signaling overhead.
