Abstract
A wireless device, network node and methods are provided. The network node includes processing circuitry configured to configure an aperiodic sounding reference signal, A-SRS, switching trigger, and transmit the configured A-SRS 5 switching trigger to a wireless device. The A-SRS switching trigger is one of: a downlink control information, DCI, of a predetermined DCI format and a DCI of another predetermined DCI format for group switching. In one embodiment, the predetermined DCI format is one of 2, 2A and 3, and the other predetermined DCI format for group switching is 1A. 10
Claims23
A network node, comprising:
- processing circuitry configured to:
- configure an aperiodic sounding reference signal, A-SRS, carrier switching trigger, the A-SRS carrier switching trigger configured to cause a wireless device to perform A-SRS carrier switching from a first carrier to second carrier for transmitting an A-SRS using the second carrier;
- and
- transmit the configured A-SRS carrier switching trigger to the wireless device.
2-10. (canceled)
A method for a network node, the method comprising:
- configuring an aperiodic sounding reference signal, A-SRS, carrier switching trigger, the A-SRS carrier switching trigger configured to cause a wireless device to perform A-SRS carrier switching from a first carrier to second carrier for transmitting an A-SRS using the second carrier;
- and
- transmitting the configured A-SRS carrier switching trigger to the wireless device.
A wireless device, comprising:
- processing circuitry configured to:
- receive an aperiodic sounding reference signal, A-SRS, carrier switching trigger;
- perform A-SRS carrier switching from a first carrier to second carrier for transmitting an A-SRS using the second carrier based on the A-SRS carrier switching trigger;
- and
- transmit A-SRS on the second carrier.
22-30. (canceled)
A method for a wireless device, the method comprising:
- receiving an aperiodic sounding reference signal, A-SRS, carrier switching trigger;
- performing A-SRS carrier switching from a first carrier to second carrier for transmitting an A-SRS using the second carrier based on the A-SRS carrier switching trigger;
- and
- transmitting A-SRS on the second carrier.
