Classification: CPC H | IPC H

Claim 14:
15. A method of wireless communication at a user equipment (UE), comprising:
selecting a physical random access channel (PRACH) preamble sequence from a set of available preamble sequences;
selecting one or more parameters of a time-frequency resource based on a first predetermined number of bits of a user equipment identity (UE ID) associated with the UE;
including a second predetermined number of bits of the UE ID in a first message;
transmitting a first transmission for a random access procedure using the time-frequency resource, the first transmission comprising the selected PRACH preamble sequence and the first message; and
receiving a second transmission including:
information on a physical downlink control channel (PDCCH) addressed to 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, and
a second message on a physical downlink shared channel (PDSCH) associated with the PDCCH;
wherein the second message 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.
