Multiplexing control information in a physical uplink data channel
For multiplexing control information in a physical uplink data channel, a user equipment (UE) includes receiving a configuration for a first set of values and receiving a downlink control information (DCI) format scheduling a transmission of a physical uplink shared data channel (PUSCH) over a set of resource elements (REs) and including a field providing an index. The method further includes determining a first value from the first set of values based on the index, determining a first subset of REs from the set of REs, for multiplexing first uplink control information (UCI), based on the first value, and transmitting the first UCI in the PUSCH.
