Abstract
Wireless communications are described. A wireless device may be configured to transmit a first signal via a first cell group that may overlap in time with a second signal via a second cell group. The wireless device may adjust a signal transmission power of at least one of the first signal or the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal or the second signal. Adjusting and/or dropping at least one of the first signal or the second signal may be based on the overlap in time of these signals satisfying a duration threshold and a total power to transmit the first signal and the second signal exceeding a power threshold.
Claims27
A method comprising:
- receiving, by a wireless device, configuration parameters of a first cell group and a second cell group, wherein:
- uplink transmission timing associated with the first cell group is based on a first cell of the first cell group;
- and
- uplink transmission timing associated with the second cell group is based on a second cell of the second cell group;
- and
- transmitting a first signal in a first time interval of the first cell group, wherein the first signal overlaps, in time during an overlap period, with a scheduled transmission of a second signal in a second time interval of the second cell group, and wherein a signal transmission power of the first signal, during the overlap period and during a non-overlap period, is reduced based on a power value exceeding a maximum transmission power and a duration of the overlap period satisfying a duration threshold.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configure the wireless device to:
- receive configuration parameters of a first cell group and a second cell group, wherein:
- uplink transmission timing associated with the first cell group is based on a first cell of the first cell group;
- and
- uplink transmission timing associated with the second cell group is based on a second cell of the second cell group;
- and
- transmit a first signal in a first time interval of the first cell group, wherein the first signal overlaps, in time during an overlap period, with a scheduled transmission of a second signal in a second time interval of the second cell group, and wherein a signal transmission power of the first signal, during the overlap period and during a non-overlap period, is reduced based on a power value exceeding a maximum transmission power and a duration of the overlap period satisfying a duration threshold.
A non-transitory computer-readable medium storing instructions that, when executed, configure a wireless device to:
- receive configuration parameters of a first cell group and a second cell group, wherein:
- uplink transmission timing associated with the first cell group is based on a first cell of the first cell group;
- and
- uplink transmission timing associated with the second cell group is based on a second cell of the second cell group;
- and
- transmit a first signal in a first time interval of the first cell group, wherein the first signal overlaps, in time during an overlap period, with a scheduled transmission of a second signal in a second time interval of the second cell group, and wherein a signal transmission power of the first signal, during the overlap period and during a non-overlap period, is reduced based on a power value exceeding a maximum transmission power and a duration of the overlap period satisfying a duration threshold.
A system comprising:
- a base station;
- and
- a wireless device,
- wherein the base station is configured to transmit configuration parameters of a first cell group and a second cell group, wherein:
- uplink transmission timing associated with the first cell group is based on a first cell of the first cell group;
- and
- uplink transmission timing associated with the second cell group is based on a second cell of the second cell group, and
- wherein the wireless device is configured to:
- receive the configuration parameters;
- and
- transmit a first signal in a first time interval of the first cell group, wherein the first signal overlaps, in time during an overlap period, with a scheduled transmission of a second signal in a second time interval of the second cell group, and wherein a signal transmission power of the first signal, during the overlap period and during a non-overlap period, is reduced based on a power value exceeding a maximum transmission power and a duration of the overlap period satisfying a duration threshold.
