Abstract
Embodiments of the present disclosure relate to aperiodic sounding reference signal (SRS) transmission. According to embodiments of the present disclosure, the collision of the triggered SRS resource sets (such as, the SRS resource set being triggered too early or the triggered SRS resource sets being overlapped in time and/or frequency domain) may be well handled, and the configuring and updating procedures for SRS resource may be more flexible.
Claims21
A processor of a user equipment (UE) configured to perform operations comprising:
- receiving, from a network, one or more first messages for triggering an aperiodic sounding reference signal (SRS) transmission, the one or more first messages indicating at least one SRS resource set including at least one of the following:
- a first resource set of the at least one SRS resource set, being at least partially overlapping with a second resource set of the at least one SRS resource set, or
- a third resource set of the at least one SRS resource set, being configured with a timing offset smaller than a timing offset threshold;
- and
- performing, with the network, the aperiodic SRS transmission based on the one or more first messages.
A processor of a user equipment (UE) configured to perform operations comprising:
- receiving, from a network, a second message for configuring resources for an aperiodic sounding reference signal (SRS) transmission, the second message comprising information indicating a SRS resource set, the information comprising at least one of the following:
- an identification of a component carrier corresponding to the SRS resource set, or a plurality of aperiodic SRS resource trigger states corresponding to the SRS resource set.
19-22. (canceled)
A processor of a base station (BS) configured to perform operations comprising:
- transmitting, to a user equipment (UE), one or more first messages for triggering an aperiodic sounding reference signal (SRS) transmission, the one or more first messages indicating at least one SRS resource set comprising at least one of the following:
- a first resource set of the at least one SRS resource set, being at least partially overlapping with a second resource set of the at least one SRS resource set, or
- a third resource set of the at least one SRS resource set with a timing offset being smaller that a timing offset threshold;
- and
- performing, with the UE, the aperiodic SRS transmission based on the one or more first messages.
