Classification: CPC H | IPC H

Claim 0:
1. A base station, comprising:
a transceiver;
a memory; and
one or more processors coupled to the transceiver and the memory, the one or more processors configured to:
receive via the transceiver a first transmission from a user equipment (UE) for a random access procedure using a time-frequency resource, one or more parameters of the time-frequency resource being based on a first predetermined number of bits of a user equipment identity (UE ID) associated with the UE, the first transmission comprising a physical random access channel (PRACH) preamble sequence and a first message including at least a second predetermined number of bits of the UE ID;
determine a temporary identifier associated with the UE based on the second predetermined number of bits of the UE ID and the one or more parameters of the time-frequency resource used to receive at least the PRACH preamble sequence;
detect the PRACH preamble sequence;
decode the first message; and
in response to successfully detecting the PRACH preamble sequence and decoding the first message of the first transmission, transmit via the transceiver a second transmission including:
information on a physical downlink control channel (PDCCH) addressed to the temporary identifier associated with UE, and
a second message on a physical downlink shared channel (PDSCH) associated with the PDCCH,
wherein the second message on the PDSCH comprises at least one of an indication confirming the PRACH preamble sequence, a timing advance value, a back-off indicator, a contention resolution message, a transmit power control (TPC) command, an uplink resource grant, or a downlink resource grant, specific to the UE.
