US Patent 11770855 Random access channel (RACH) procedure design

Certain aspects of the present disclosure are generally directed to design of random access channel (RACH) procedures. For example, certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The method generally includes receiving an indication of a RACH procedure capability of a network entity, and selecting a first RACH procedure or a second RACH procedure, based on the indication. The UE may then communicate one or more messages with the network entity based on the selected first RACH procedure or the selected second RACH procedure.
