Abstract: Methods, systems, and devices are described for transmitting multiple repetitions of a random access shared channel message in multiple slots using beamformed wireless communications. A UE may determine transmission slots for one or more of the multiple repetitions of a random access shared channel message based on slots associated with random access occasions (ROs) that are mapped to an identified synchronization signal block (SSB), such as a SSB associated with a beam that is selected for communications by the UE. In cases where slots with ROs mapped to the identified SSB are not consecutively located, one or more slot offsets may be provided for transmitting the multiple repetitions of the random access shared channel message. Slot offsets may be explicitly indicated by a base station in a random access response message, or may be determined by the UE based on a mapping of SSBs to ROs.
