Abstract:
Embodiments are generally directed to establishment of random access channel communications. An embodiment of an apparatus for a user equipment (UE) to perform a random access (RACH) procedure, the apparatus including one or more baseband processors to generate a first Radio Resource Control (RRC) RACH procedure message to transmit to an Evolved Node B (eNB) or Next Generation Node B (gNB), the first RRC RACH procedure message including a UE identification (ID) and a request message with scheduled transmission content data, the UE ID being a common UE ID for RACH procedures between the UE and the eNB or gNB, and process a second RRC RACH procedure message received from the eNB or gNB, the second RRC RACH procedure message including contention resolution data for a random access preamble and the request message; and a memory to store data for the RACH procedure.
