Abstract
A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups. The cells are in the same timing advance group. A first sounding reference signal (SRS) is transmitted via a first cell of a first PUCCH group in parallel with transmission of a first PUCCH via a second cell of a second PUCCH group. In response to a second PUCCH being transmitted via the first cell in parallel with a configured transmission of a second SRS, the configured transmission of the second SRS via the first cell is dropped.
Claims20
A method comprising:
- receiving, by a wireless device, configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups, wherein the cells are in the same timing advance group;
- transmitting a first sounding reference signal (SRS) via a first cell of a first PUCCH group in parallel with transmission of a first PUCCH via a second cell of a second PUCCH group;
- and
- dropping, in response to a second PUCCH being transmitted via the first cell in parallel with a configured transmission of a second SRS, the configured transmission of the second SRS via the first cell.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups, wherein the cells are in the same timing advance group;
- transmit a first sounding reference signal (SRS) via a first cell of a first PUCCH group in parallel with transmission of a first PUCCH via a second cell of a second PUCCH group;
- and
- drop, in response to a second PUCCH being transmitted via the first cell in parallel with a configured transmission of a second SRS, the configured transmission of the second SRS via the first cell.
A system comprising:
- a base station comprising:
- one or more first processors;
- and
- first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
- transmit configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups, wherein the cells are in the same timing advance group;
- and
- a wireless device comprising:
- one or more second processors;
- and
- second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
- receive the configuration parameters;
- transmit a first sounding reference signal (SRS) via a first cell of a first PUCCH group in parallel with transmission of a first PUCCH via a second cell of a second PUCCH group;
- and
- drop, in response to a second PUCCH being transmitted via the first cell in parallel with a configured transmission of a second SRS, the configured transmission of the second SRS via the first cell.
