Claim 29:
30. An apparatus for wireless communication at a base station, comprising:
a processor; and
a memory coupled with the processor, with instructions stored in the memory, the instructions being executable by the processor to cause the apparatus to:
determine a plurality of configurations of physical resources and transmission parameters usable by a plurality of user equipment (UEs), while operating in a non-connected state, for grant-free uplink transmission;
transmit, in one or more group common downlink control channels, group common downlink control information including at least scheduling information and a group radio network temporary identifier associated with each of a plurality of downlink data channels;
scramble each of the plurality of downlink data channels with a respective group radio network temporary identifier;
multicast, for each downlink data channel of the plurality of downlink data channels, a configuration of physical resources and transmission parameters of the plurality of configurations for a subset of the plurality of UEs according to the scheduling information transmitted in the one or more group common downlink control channels; and
multiplex each downlink data channel with other downlink data channels of the plurality of downlink data channels scheduled by the one or more group common downlink control channels, based on a multiplexing scheme comprising one or more of code division multiplexing, frequency division multiplexing, space division multiplexing, or time division multiplexing.
