Claim 15:
16. A user equipment comprising:
a processor; and
a memory system storing processor-executable instructions that, responsive to execution by the processor, direct the user equipment to perform operations comprising:
receiving a non-orthogonal multiple access configuration message from a base station, the non-orthogonal multiple access configuration message including a plurality of multiple access signatures and available time-frequency resources for uplink transmissions;
deriving a group user equipment identifier (a group UE-ID) from at least a user equipment-specific identifier (a UE-specific ID) assigned to the user equipment, the group UE-ID corresponding to a group of user equipments that includes the user equipment;
while operating in a radio resource control inactive (RRC inactive) state or a radio resource control idle (RRC idle) state, selecting, for at least a first uplink transmission, a multiple access signature from the plurality of multiple access signatures;
transmitting, using an uplink control channel, uplink control information in the first uplink transmission using a first time-frequency resource of the available time-frequency resources and the selected multiple access signature; and
transmitting, using an uplink data channel, uplink data in a second uplink transmission using a second time-frequency resource of the available time-frequency resources and at least based on the uplink control information.
