DYNAMIC RACH MSG1/MSGA CONFIGURATION

Abstract:

A user equipment (UE) and a base station may perform a random access procedure based on a dynamic physical random access channel (PRACH) configuration. The UE may determine a first PRACH configuration, for example, based on system information. The UE may determine a second PRACH configuration, for example, based on a dynamic configuration message. The UE may determine to follow the second PRACH configuration based on a current time or the dynamic configuration message. The UE may transmit a first message of a random access (RACH) procedure based on the second PRACH configuration.
