Method and apparatus for multiplexing uci

A base station (BS) comprising:

• one or more processors;
• and
• at least one memory coupled to the one or more processors, wherein the at least one memory stores a computer-executable program that, when executed by the one or more processors, causes the BS to:
• transmit, to a user equipment (UE), a Radio Resource Control (RRC) configuration to configure a first sequence associated with a first RRC parameter and a second sequence associated with a second RRC parameter;
• transmit, to the UE, a first downlink control information (DCI) format including a first indicator and a second DCI format including a second indicator;
• and
• receive, from the UE, an uplink control information (UCI) message which is multiplexed by the UE based on one of a first value corresponding to the first indicator and a second value corresponding to the second indicator,
• wherein:
• the first value corresponding to the first indicator is determined by the UE based on the first sequence, and
• the second value corresponding to the second indicator is determined by the UE based on the second sequence.
