Abstract
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.
Claims20
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;
- and
- uplink 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;
- and
- if 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;
- and
- transmit a second subset of the SRSs.
A method comprising:
- receiving 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;
- and
- uplink transmission timing in the second cell group is derived employing a second cell in the second cell group;
- transmitting a first signal on a cell of the first cell group;
- and
- if 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:
- dropping a first subset of the SRSs;
- and
- transmitting a second subset of the SRSs.
