Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a physical downlink control channel (PDCCH) component of a message B (msgB) communication to include a first portion of the signaling information for physical uplink control channel (PUCCH) for hybrid automatic repeat request (HARQ) feedback associated with the msgB communication and the signaling information for HARQ combining of msgB. The BS may configure a physical downlink shared channel (PDSCH) component of the msgB communication to include a second portion of the signaling information for PUCCH and msgB HARQ combining. The distributed mapping for the signaling information to the PDCCH and PDSCH components of msgB can be indicated by system information, RRC signaling, or hard coded in specifications. The BS may transmit the msgB communication to one or more UEs. Numerous other aspects are provided.
