1. A method for use in a wireless device, the method comprising:
- a) receiving at least one message causing configuration of;
i) a plurality of cells grouped into a plurality of cell groups; and
ii) transmissions of sounding reference signals (SRSs) on a first cell assigned to a first cell group in said plurality of cell groups;
b) transmitting a first transmission of said SRSs in parallel with transmission of at least one of;
i) a first random access preamble in a second cell group different from said first cell group; and
ii) a first packet on a second cell different from said first cell; and
c) dropping a second transmission of said SRSs in a symbol if at least one of the following conditions is satisfied;
i) a second random access preamble is transmitted overlapping said symbol in said first cell group; and
ii) a second packet is transmitted overlapping said symbol in said first cell; and
iii) said wireless device has insufficient power to transmit said second transmission in parallel with other uplink transmissions in said plurality of cells.

Abstract
A first transmission of sounding reference signals is on a first cell of a first cell group in parallel with transmission of at least one of a first random access preamble in a second cell group, and a first uplink packet on a second cell. The wireless device drops a second transmission of sounding reference signals in a symbol of the first cell if at least one of the following conditions is satisfied: a second random access preamble is transmitted overlapping the symbol in the first cell group, and a second uplink packet is transmitted overlapping the symbol in the first cell.

11. 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 causing configuration of; (1) a plurality of cells grouped into a plurality of cell groups; and (2) transmissions of sounding reference signals (SRSs) on a first cell assigned to a first cell group in said plurality of cell groups; ii) transmit a first transmission of said SRSs in parallel with transmission of at least one of; (1) a first random access preamble in a second cell group different from said first cell group; and (2) a first packet on a second cell different from said first cell; and iii) drop a second transmission of said SRSs in a symbol if at least one of the following conditions is satisfied; (1) a second random access preamble is transmitted overlapping said symbol in said first cell group; and (2) a second packet is transmitted overlapping said symbol in said first cell. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
