Managing sounding reference signals in a wireless device
First Claim
Patent Images
1. A wireless device comprising:
- one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to;
receive at least one control message comprising configuration parameters of a plurality of cells comprising a first cell group and a second cell group;
transmit a first sounding reference signal (SRS) via the first cell group overlapping in time with a transmission of a first random access preamble via the second cell group, wherein the wireless device has sufficient transmission power to transmit the first SRS and the first random access preamble; and
drop a configured transmission of a second SRS via the first cell group if;
the configured transmission of the second SRS and a second random access preamble transmission via the second cell group overlap in time; and
the wireless device has insufficient transmission power to transmit the second SRS in parallel with the second random access preamble.

Abstract
A wireless device receives a control message comprising configuration parameters of a plurality of cells grouped into a plurality of cell groups. The wireless device transmits a first sounding reference signal (SRS) in a first cell group overlapping in time with transmission of a first random access preamble in a second cell group. Transmission of a second SRS in the first cell group is dropped if: the second SRS transmission and a second random access preamble transmission in the second cell group overlap in time and the wireless device has insufficient transmission power.
