Abstract

A wireless device receives configuration parameters of: first cell(s) in a first frequency band; and second cell(s) in a second frequency band. A calculated total transmit power for signals is determined that comprise: a first SRS configured for transmission, during a time interval, via the first cell(s); and a second SRS configured for transmission, during the time interval, via the second cell(s). At least one of the first SRS or the second SRS is dropped or scaled based on an SRS transmit power priority of the first SRS and the second SRS when the calculated total transmit power exceeds a first value. The SRS transmit power priority is based on: a frequency band of the first cell(s) or the second cell(s); and whether the first SRS or the second SRS is configured for transmission in the first frequency band or the second frequency band.

Dependent claims

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 configuration parameters of:
one or more first cells in a first frequency band;
and
one or more second cells in a second frequency band;
determine a calculated total transmit power for a plurality of signals comprising:
a first sounding reference signal (SRS) configured for transmission, during a time interval, via the one or more first cells;
and
a second SRS configured for transmission, during the time interval, via the one or more second cells;
and
drop or scale at least one of the first SRS or the second SRS based on an SRS transmit power priority of the first SRS and the second SRS when the calculated total transmit power exceeds a first value;
and
wherein the SRS transmit power priority is based on:
a frequency band of the one or more first cells or the one or more second cells;
and
whether the first SRS or the second SRS is configured for transmission in the first frequency band or the second frequency band.
