Signal transmission power adjustment in a wireless device
First Claim
1. A method comprising:
- receiving, by a wireless device, at least one control message comprising configuration parameters of a plurality of cells grouped into a plurality of cell groups comprising 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;
determining a transmission power of a transmission comprising a first signal in a first subframe of the first cell group and a second signal in a second subframe of the second cell group, wherein a time overlap is associated with the first signal in the first subframe and the second signal in the second subframe;
responsive to the time overlap satisfying a duration threshold and the transmission power exceeding a power threshold, dropping or adjusting a power of one of the first signal or the second signal; and
transmitting at least one of the first signal via the first cell group or the second signal via the second cell group.

Abstract
Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. 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 and the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal and the second signal. Adjusting and/or dropping at least one of the first signal and 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.
