Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may extract, from a neighboring base station with cell coverage that overlaps cell coverage of the base station, information associated with user equipment (UE) transmission of MsgA messages. The base station may select, based at least in part on the information, a physical uplink shared channel (PUSCH) resource to allocate to a UE for transmission of a MsgA message. The base station may transmit, to the UE, an allocation of the PUSCH resource. Numerous other aspects are described.
