Uplink channel switching capability and selecting between uplink channels in a cell group based thereon

A base station comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• receive, from a wireless device, a capability message indicating a physical uplink control channel (PUCCH) switching capability of the wireless device;
• transmit, to the wireless device and based on the PUCCH switching capability, one or more messages comprising configuration parameters of a first PUCCH and a second PUCCH of a cell group;
• select a PUCCH from the first PUCCH and the second PUCCH of the same cell group;
• transmit, to the wireless device, downlink control information (DCI) indicating:
• a downlink transmission of a transport block;
• and
• the selected PUCCH;
• and
• receive, from the wireless device via the selected PUCCH, a hybrid automatic repeat request (HARQ) feedback for the transport block.

A system comprising:

• a base station comprising one or more first processors and first memory storing instructions that, when executed by the one or more first processors, cause the base station to:
• receive a capability message indicating a physical uplink control channel (PUCCH) switching capability;
• transmit, based on the PUCCH switching capability, one or more messages comprising configuration parameters of a first PUCCH and a second PUCCH of a cell group;
• select a PUCCH from the first PUCCH and the second PUCCH of the same cell group;
• transmit downlink control information (DCI) indicating:
• a downlink transmission of a transport block;
• and
• the selected PUCCH;
• and
• receive, via the selected PUCCH, a hybrid automatic repeat request (HARQ) feedback for the transport block;
• and
• a wireless device comprising one or more second processors and second memory storing instructions that, when executed by the one or more second processors, cause the wireless device to:
• transmit, to the base station, the capability message indicating the PUCCH switching capability of the wireless device;
• receive, from the base station based on the PUCCH switching capability, one or more messages comprising configuration parameters of a first PUCCH and a second PUCCH of a cell group;
• receive, from the base station, the DCI;
• select the selected PUCCH, indicated by the DCI, from the first PUCCH and the second PUCCH of the same cell group;
• and
• transmit, to the base station, the HARQ feedback for the transport block via the selected PUCCH.
