Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information for a two-step random access procedure. The UE may determine a frequency hopping space for transmitting a payload of a two-step random access channel of the two-step random access procedure. The UE may encode the payload into one or more codewords. The UE may map the one or more codewords to a plurality of resource units of the frequency hopping space. The UE may transmit the one or more codewords to the base station on the plurality of resource units of the frequency hopping space. Numerous other aspects are provided.
