Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a communication system may include receiving, via a higher layer signaling, a sounding reference signal (SRS) configuration including SRS resource sets configured with antenna switching; receiving downlink control information (DCI) for SRS triggering; and transmitting an SRS based on the SRS configuration and the DCI.
Claims20
A method performed by a user equipment (UE) in a communication system, the method comprising:
- receiving, via a higher layer signaling, a sounding reference signal (SRS) configuration including SRS resource set configurations, wherein each of the SRS resource set configurations includes a higher layer parameter usage set as antenna switching;
- receiving downlink control information (DCI) for SRS triggering;
- and
- transmitting an SRS based on the SRS configuration after receiving the DCI,
- wherein in case that none of SRS resource sets corresponding to the SRS resource set configurations is configured with a higher layer parameter availableSlotOffsetList, a value of a higher layer parameter slotOffset in each SRS resource set configuration is different.
A user equipment (UE) in a communication system, the UE comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to:
- receive, via a higher layer signaling, a sounding reference signal (SRS) configuration including SRS resource set configurations, wherein each of the SRS resource set configurations includes a higher layer parameter usage set as antenna switching;
- receive downlink control information (DCI) for SRS triggering;
- and
- transmit an SRS based on the SRS configuration after receiving the DCI,
- wherein in case that none of SRS resource sets corresponding to the SRS resource set configurations is configured with a higher layer parameter availableSlotOffsetList, a value of a higher layer parameter slotOffset in each SRS resource set configuration is different.
A method performed by a base station in a communication system, the method comprising:
- transmitting, to a user equipment (UE) via a higher layer signaling, a sounding reference signal (SRS) configuration including SRS resource set configurations, wherein each of the SRS resource set configurations includes a higher layer parameter usage set as configured with antenna switching;
- transmitting, to the UE, downlink control information (DCI) for SRS triggering;
- and
- receiving, from the UE, an SRS associated with the SRS configuration after transmitting the DCI,
- wherein in case that none of SRS resource sets corresponding to the SRS resource set configurations is configured with a higher layer parameter availableSlotOffsetList, a value of a higher layer parameter slotOffset in each SRS resource set configuration is different.

- transmit, to the UE, downlink control information (DCI) for SRS triggering;
- and
- receive, from the UE, an SRS associated with the SRS configuration after transmitting the DCI,
- wherein in case that none of SRS resource sets corresponding to the SRS resource set configurations is configured with a higher layer parameter availableSlotOffsetList, a value of a higher layer parameter slotOffset in each SRS resource set configuration is different.
