Abstract
A wireless device receives message(s) configuring cell groups and transmissions of sounding reference signals. Sounding reference signals are configured to be transmitted in a subframe. The wireless device transmits at least one packet on at least one first cell in the subframe. The wireless device transmits a first subset of the sounding reference signals and drops a second subset of the sounding reference signals.

1-20. (canceled)
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) n sounding reference signals (SRSs) configured to be transmitted in a plurality of subframes, n being greater than one;
- ii) transmit, on a first cell of a first cell group in said plurality of cell groups, a packet in a plurality of symbols of a first subframe in said plurality of subframes, said plurality of symbols comprising the last symbol of said first subframe;
- iii) transmit a first subset of said n SRSs in said last symbol, said first subset consisting of k SRSs, wherein 1<=k<n;
- and
- iv) drop a second subset of said n SRSs in said last symbol, said second subset consisting of m SRSs, wherein 1<=m<n.
