Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink communication on a sidelink between the UE and another UE. The UE may transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a reporting period having a configurable periodicity and/or being configured to occupy an entire bandwidth of a resource pool configured for the sidelink. Numerous other aspects are provided.
Claims56
An apparatus for wireless communication at a user equipment (UE), comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the UE to:
- receive a sidelink communication in one or more slots on a sidelink between the UE and another UE;
- and
- transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a feedback reporting resource, in a physical sidelink feedback channel (PSFCH), wherein the feedback reporting resource includes one or more symbols, wherein the one or more symbols are located at an end of a particular slot of a plurality of sidelink slots included in a feedback reporting period, wherein a first turnaround symbol is located before the one or more symbols and a second turnaround symbol is located after the one or more symbols, and wherein the particular slot comprises a first slot of the plurality of sidelink slots included in the feedback reporting period.
A method of wireless communication performed at a user equipment (UE), comprising:
- receiving a sidelink communication in one or more slots on a sidelink between the UE and another UE;
- and
- transmitting, on the sidelink, one or more feedback communications associated with the sidelink communication in a feedback reporting resource, in a physical sidelink feedback channel (PSFCH), wherein the feedback reporting resource includes one or more symbols, wherein the one or more symbols are located at an end of a particular slot of a plurality of sidelink slots included in a feedback reporting period, wherein a first turnaround symbol is located before the one or more symbols and a second turnaround symbol is located after the one or more symbols, and wherein the particular slot comprises a first slot of the plurality of sidelink slots included in the feedback reporting period.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
- receive a sidelink communication in one or more slots on a sidelink between the UE and another UE;
- and
- transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a feedback reporting resource, in a physical sidelink feedback channel (PSFCH), wherein the feedback reporting resource includes one or more symbols, wherein the one or more symbols are located at an end of a particular slot of a plurality of sidelink slots included in a feedback reporting period, wherein a first turnaround symbol is located before the one or more symbols and a second turnaround symbol is located after the one or more symbols, and wherein the particular slot comprises a first slot of the plurality of sidelink slots included in the feedback reporting period.
An apparatus for wireless communication, comprising:
- means for receiving a sidelink communication in one or more slots on a sidelink between the apparatus and another apparatus;
- and
- means for transmitting, on the sidelink, one or more feedback communications associated with the sidelink communication in a feedback reporting resource, in a physical sidelink feedback channel (PSFCH), wherein the feedback reporting resource includes one or more symbols, wherein the one or more symbols are located at an end of a particular slot of a plurality of sidelink slots included in a feedback reporting period, wherein a first turnaround symbol is located before the one or more symbols and a second turnaround symbol is located after the one or more symbols, and wherein the particular slot comprises a first slot of the plurality of sidelink slots included in the feedback reporting period.
