1. 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 message comprising configuration parameters of;
(1) a plurality of cells grouped into a plurality of cell groups; and
(2) sounding reference signals (SRSs);
ii) decode at least one information element triggering transmission of said SRSs, one of said SRSs being scheduled for transmission in the last symbol of subframe n on a first cell in a first cell group in said plurality of cell groups, said last symbol overlapping in time with transmission of an uplink packet in subframe n+1 in a second cell in a second cell group of said plurality of cell groups, said second cell group being different from said first cell group; and
iii) transmit said one of said SRSs if a power value is less than or equal to a maximum allowable transmission power in said symbol, a calculation of said power value considering transmission power of said uplink packet if said overlap in time exceeds a first duration.

Abstract
A sounding reference signal (SRS) is being scheduled for transmission in the last symbol of subframe n on a first cell in a first cell group. The last symbol overlaps in time with transmission of an uplink packet in subframe n+1 in a second cell in a second cell group. The wireless device transmits the SRS if a power parameter is less than or equal to a maximum allowable transmission power in the symbol. A calculation of the power parameter considers transmission power of the uplink packet if the overlap in time exceeds a first duration.

11. A method for use by a wireless device, the method comprising:
-
a) receiving at least one message comprising configuration parameters of; i) a plurality of cells grouped into a plurality of cell groups; and ii) sounding reference signals (SRSs); b) decoding at least one information element triggering transmission of said SRSs, one of said SRSs being scheduled for transmission in the last symbol of subframe n on a first cell in a first cell group in said plurality of cell groups, said last symbol overlapping in time with transmission of an uplink packet in subframe n+1 in a second cell in a second cell group of said plurality of cell groups, said second cell group being different from said first cell group; and c) transmitting said one of said SRSs if a power value is less than or equal to a maximum allowable transmission power in said symbol, a calculation of said power value considering transmission power of said uplink packet if said overlap in time exceeds a first duration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
