Abstract
Aspects are provided to support payloads for msgA transmission in a two-step random access (RACH) procedure by providing a one-to-many mapping arrangement between preambles and physical uplink shared channel (PUSCH) resource units (PRUs). A preamble is determined by the UE which is mapped to one or more groups of PRUs to support piggybacking of uplink control information (UCI), frequency hopping on PUSCH, and multiple-slot repetition for msgA transmissions. By piggybacking UCI to a payload in msgA, flexibility may be provided in the selection of MCS and waveform as well as resource allocation for demodulation reference signals (DMRS) and PUSCH in PRUs. Moreover, by allowing a payload to hop to different frequencies on PUSCH during the transmission of msgA, a gain in frequency diversity and interference averaging may be provided, and by enabling a payload to repeat across multiple slots in msgA transmission, coverage enhancement and/or reliability may be increased.
