Claim 19:
20. A method for a user equipment (UE) to perform uplink control information (UCI) multiplexing with physical layer (PHY) priority and logical channel (LCH) based prioritization, the method comprising:
determining, at a PHY entity of the UE, a scheduling request (SR) status for an SR based on whether an SR status indication is received from a media access control (MAC) entity of the UE;
identifying, at the PHY entity of the UE, a target physical uplink shared channel (PUSCH) for UCI multiplexing based at least in part on PHY priority rules and the SR status;
indicating, from the PHY entity to the MAC entity, a physical uplink control channel (PUCCH) resource Z and UCI contents of the PUCCH resource Z, wherein indicating the PUCCH resource Z includes indicating a starting symbol and a duration of a PUCCH corresponding to the target PUSCH, and wherein the UCI contents includes the SR;
receiving, at the PHY entity, transport blocks from the MAC entity; and
generating, at the PHY entity, uplink transmissions for the transport blocks,
wherein if the MAC entity does not generate a MAC protocol data unit (PDU) for the target PUSCH or another PUSCH corresponding to one of the transport blocks delivered by the MAC entity at least partially overlaps with the target PUSCH, and if the transmission of the PUCCH resource Z would overlap with any PUSCH on a same component carrier or on another component carrier, the PHY entity transmits neither the target PUSCH nor the PUCCH resource Z,
wherein if the MAC entity does not generate the MAC PDU for the target PUSCH or another PUSCH corresponding to one of the transport blocks delivered by the MAC entity at least partially overlaps with the target PUSCH, and if the transmission of the PUCCH resource Z would not overlap with any PUSCH on the same component carrier or on another component carrier, the PHY entity transmits over the PUCCH resource Z, and
wherein if the MAC entity generates the MAC PDU for the target PUSCH or the target PUSCH is without an uplink shared channel (UL-SCH) and is not dropped due to another PUSCH corresponding to one of the transport blocks delivered by the MAC entity, the PHY entity multiplexes the UCI, except for the SR, over the target PUSCH.
