Abstract
A wireless device transmits a first packet in subframe n of a first cell of a first cell group and transmits a second packet in subframe n+1 of a second cell of a second cell group overlapping in time with the transmission of the first packet. The wireless device reduces a subframe transmission power of at least one of the first packet and the second packet if a power parameter is more than an allowable transmission power. A calculation for the power parameter considers transmission power of the first packet and the second packet according to a pre-configured rule.
Claims20
A method comprising:
- a) receiving, by a wireless device, at least one radio resource control message from a base station, said at least one radio resource control message to cause in said wireless device:
- i) configuration of a plurality of cells comprising a primary cell and at least one secondary cell;
- and
- ii) assignment of each of said at least one secondary cell to a cell group in a plurality of cell groups, each of said plurality of cell groups comprising a subset of said plurality of cells;
- b) transmitting, by said wireless device, a first packet in subframe n of a first cell of a first cell group in said plurality of cell groups;
- c) transmitting, by said wireless device, a second packet in subframe n+1 of a second cell of a second cell group in said plurality of cell groups, said transmitting of said second packet overlapping in time with said transmitting of said first packet;
- and
- d) reducing, by said wireless device, a subframe transmission power of at least one of said first packet and said second packet if a power parameter is more than a maximum allowable transmission power, a calculation for said power parameter considering transmission power of said first packet and said second packet if said overlapping in time exceeds a first duration.

A wireless device comprising:
- a) one or more communication interfaces;
- b) one or more processors;
- and
- c) memory storing instructions that, when executed, cause said wireless device to:
- i) receive at least one radio resource control message from a base station, said at least one radio resource control message to cause in said wireless device assignment of each of at least one secondary cell in a plurality of cells to a cell group in a plurality of cell groups, each of said plurality of cell groups comprising a subset of said plurality of cells;
- ii) transmit a first packet in subframe n of a first cell of a first cell group in said plurality of cell groups;
