1. A method for a user equipment (UE) to perform uplink control information (UCI) multiplexing, the method comprising:
generating physical uplink control channel (PUCCH) resources Z at each of a layer 1 (L1) high priority (HP) procedure and an L1 low priority (LP) procedure, the L1 HP procedure resulting in a plurality of HP PUCCHs and the L1 LP procedure resulting in a plurality of LP PUCCHs;
performing a modified procedure for Set Q to resources Z with the plurality of HP PUCCHs and the plurality of LP PUCCHs as inputs, the modified procedure including at least:
scanning the plurality of HP PUCCHs according to starting symbols to identify an earliest starting HP PUCCH of the plurality of HP PUCCHs;
collecting at least one PUCCH from the plurality of LP PUCCHs or the plurality of HP PUCCHS that overlaps with the earliest starting HP PUCCH;
performing inter-L1 priority multiplexing on the earliest starting HP PUCCH and the at least one collected PUCCH, performing inter-L1 multiplexing resulting in a new HP PUCCH;
inserting the new HP PUCCH into the Set Q; and
repeating the modified procedure until there is no overlap among the plurality of HP PUCCHs and the plurality of LP PUCCHs.
