Managing Sounding Signals to Limit Power in a Multicarrier Wireless Device

摘要

A wireless device receives message(s) configuring cell groups and transmissions of sounding reference signals (SRSs). Uplink transmission timing in a first cell group is derived employing a cell in the first cell group and uplink transmission timing in a second cell group is derived employing a second cell in the second cell group. A first signal is transmitted on a cell of the first cell group. A first subset of the SRSs are dropped and a second subset of the SRSs are transmitted if transmission of SRSs overlap in time with transmission of the first signal and a calculated total transmission power exceeds a first power value.

1. A wireless device comprising:
one or more processors; and memory storing instructions that, when executed, cause the wireless device to:
receive at least one message comprising configuration parameters of a plurality of cells being grouped into a plurality of cell groups comprising a first cell group and a second cell group, wherein:
uplink transmission timing in the first cell group is derived employing a first cell in the first cell group; anduplink transmission timing in the second cell group is derived employing a second cell in the second cell group;transmit a first signal on a cell of the first cell group; andif a configured transmission of sounding reference signals (SRSs) overlaps in time with transmission of the first signal and if a calculated total transmission power exceeds a first power value:drop a first subset of the SRSs; andtransmit a second subset of the SRSs.
