Multiplexing of uplink control information

A user equipment (UE), comprising:

• a radio;
• and
• a processor operably connected to the radio and configured to cause the UE to:
• establish communication with a base station;
• determine whether to multiplex first uplink control information (UCI) of a first physical uplink control channel (PUCCH) having a first physical layer priority, wherein, in the determining whether to multiplex the first UCI, the UE is configured to:
• identify whether one or more timing resources of the first PUCCH overlap with one or more timing resources of a first physical uplink shared channel (PUSCH) having the first physical layer priority,
• subsequent to identifying whether the one or more timing resources of the first PUCCH overlap with the one or more timing resources of the first PUSCH, identify whether the one or more timing resources of the first PUCCH overlap with one or more timing resources of a second PUCCH having a second physical layer priority different from the first physical layer priority, and
• subsequent to identifying whether the one or more timing resources of the first PUCCH overlap with the one or more timing resources of the second PUCCH, identify whether the one or more timing resources of the first PUCCH overlap with one or more timing resources of a second PUSCH having a third physical layer priority;
• and
• multiplex the first UCI based on the determination whether to multiplex the first UCI, and
• transmit the multiplexed first UCI to the base station.

A method for operating a user equipment (UE), the method comprising:

• establishing communication with a base station;
• determining whether to multiplex first uplink control information (UCI) of a first physical uplink control channel (PUCCH) having a first physical layer priority, wherein said determining comprises:
• identifying whether one or more timing resources of the first PUCCH overlap with one or more timing resources of a first physical uplink shared channel (PUSCH) having the first physical layer priority,
• subsequent to identifying whether the one or more timing resources of the first PUCCH overlap with the one or more timing resources of the first PUSCH, identifying whether the one or more timing resources of the first PUCCH overlap with one or more timing resources of a second PUCCH having a second physical layer priority different from the first physical layer priority, and
• subsequent to identifying whether the one or more timing resources of the first PUCCH overlap with the one or more timing resources of the second PUCCH, identifying whether the one or more timing resources of the first PUCCH overlap with one or more timing resources of a second PUSCH having a third physical layer priority;
• and
• multiplexing the first UCI based on the determination whether to multiplex the first UCI, and
• transmitting the multiplexed first UCI to the base station.
