PUCCH collision handling for multi-slot long PUCCH in 5G NR

A base station apparatus comprising:

• a processor configured to determine that a first physical uplink control channel (PUCCH) carrying first uplink control information (UCI) and a second PUCCH carrying second UCI overlap in a slot, the processor being configured to determine, based on a first priority for the first PUCCH and a second priority for the second PUCCH, one of the first PUCCH and the second PUCCH, a priority for the one of the first PUCCH and the second PUCCH being higher than that for the other one of the first PUCCH and the second PUCCH;
• and
• a UL receiver configured to receive, in the slot, the one of the first PUCCH and the second PUCCH, without receiving, in the slot, the other one of the first PUCCH and the second PUCCH, wherein
• the first priority for the first PUCCH is based on a type of the first UCI, and the second priority for the second PUCCH is based on a type of the second UCI,
• in a case that the type of the first UCI is Channel State Information (CSI) with higher priority and the type of the second UCI is CSI with lower priority, the one of the first PUCCH and the second PUCCH is the first PUCCH and the other one of the first PUCCH and the second PUCCH is the second PUCCH, wherein
• the first PUCCH is received whereas the second PUCCH is not received on the basis of (a) a priority rule in which semi-persistent CSI is defined to have a priority higher than periodic CSI and (b) a determination by a user equipment that the semi-persistent CSI and the periodic CSI are the CSI with higher priority and the CSI with lower priority, respectively.

A communication method of a user equipment comprising:

• determining that a first physical uplink control channel (PUCCH) carrying first uplink control information (UCI) and a second PUCCH carrying second UCI overlap in a slot;
• determining, based on a first priority for the first PUCCH and a second priority for the second PUCCH, one of the first PUCCH and the second PUCCH, a priority for the one of the first PUCCH and the second PUCCH being higher than that for the other one of the first PUCCH and the second PUCCH;
• transmitting, in the slot, the one of the first PUCCH and the second PUCCH, without transmitting, in the slot, the other one of the first PUCCH and the second PUCCH, wherein
• the first priority for the first PUCCH is based on a type of the first UCI, and the second priority for the second PUCCH is based on a type of the second UCI, and
• in a case that the type of the first UCI is Channel State Information (CSI) with higher priority and the type of the second UCI is CSI with lower priority, the one of the first PUCCH and the second PUCCH is the first PUCCH and the other one of the first PUCCH and the second PUCCH is the second PUCCH;
• determining, on the basis of a priority rule in which semi-persistent CSI is defined to have a priority higher than periodic CSI, that the semi-persistent CSI and the periodic CSI are the CSI with higher priority and the CSI with lower priority, respectively.
