Abstract
A wireless device receives a message indicating transmission of a sounding reference signal in a symbol on subframe n on a first cell in a first cell group. The symbol overlaps in time with transmission of a packet on at least one of: subframe n and n+1 in a second cell in a second cell group. The wireless device transmits the sounding reference signal if a power parameter is less than a maximum allowable transmission power in the symbol. A calculation of the power parameter considers transmission power of the 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;
- 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;
- and
- i) configuration of transmissions of sounding reference signals by said wireless device;
- b) decoding, by said wireless device, an information element in a received control message indicating transmission of one of said sounding reference signals in a symbol on subframe n on a first cell in a first cell group in said plurality of cell groups, said symbol overlapping in time with transmission of an uplink packet on at least one of:
- i) subframe n in a second cell, said second cell in a second cell group in said plurality of cell groups;
- and
- ii) subframe n+1 in said second cell;
- and
- c) transmitting, by said wireless device, said one of said sounding reference signals if a power parameter is less than a maximum allowable transmission power in said symbol, a calculation of said power parameter considering transmission power of said uplink packet if said overlapping in time exceeds a first duration.
