Abstract
A method for a wireless device operating in a wireless communication system includes receiving configuration information for configuring a non-Physical Uplink Control Channel (PUCCH) cell; and transmitting a Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell on a special cell (SpCell) or a PUCCH cell other than SpCell, according to indication information. Further, when the indication information is not received with the configuration information, the HARQ feedback is transmitted on the SpCell, and when the indication information is received with the configuration information, the HARQ feedback is transmitted on the PUCCH cell.
Claims8
A method performed by a base station operating in a wireless communication system, the method comprising:
- transmitting, to a wireless device, configuration information for configuring a non-Physical Uplink Control Channel (non-PUCCH) cell which is not configured with a PUCCH resource;
- and
- receiving, from the wireless device, Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell either (i) on a special cell (SpCell) or (ii) on a PUCCH cell other than the SpCell, based on whether the configuration information includes indication information that indicates the PUCCH cell on which the HARQ feedback of the non-PUCCH cell is to be transmitted by the wireless device,
- wherein the SpCell and the PUCCH cell are each configured with a respective PUCCH resource,
- wherein based on the configuration information including the indication information:
- the HARQ feedback of the non-PUCCH cell is received on the PUCCH cell other than the SpCell, and
- wherein based on the configuration information not including the indication information:
- the HARQ feedback of the non-PUCCH cell is received on the SpCell.
A base station configured to operate in a wireless communication system, the base station comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- transmitting, to a wireless device through the at least one transceiver, configuration information for configuring a non-Physical Uplink Control Channel (non-PUCCH) cell which is not configured with a PUCCH resource;
- and
- receiving, from the wireless device through the at least one transceiver, Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell either (i) on a special cell (SpCell) or (ii) on a PUCCH cell other than the SpCell, based on whether the configuration information includes indication information that indicates the PUCCH cell on which the HARQ feedback of the non-PUCCH cell is to be transmitted by the wireless device,
- wherein the SpCell and the PUCCH cell are each configured with a respective PUCCH resource,
- wherein based on the configuration information including the indication information:
- the HARQ feedback of the non-PUCCH cell is received on the PUCCH cell other than the SpCell, and
- wherein based on the configuration information not including the indication information:
- the HARQ feedback of the non-PUCCH cell is received on the SpCell.
