Abstract
Apparatuses, methods, and systems are disclosed for indicating a sidelink resource conflict using a feedback channel. One apparatus includes a receiver that receives SCI from a peer UE on a first resource of a PSCCH, where the SCI contains information indicating future resources reserved for future transmissions. The apparatus includes a processor that determines whether there is a resource conflict, said resource conflict including an expected collision on the future resources. The apparatus includes a transmitter that transmits feedback to the peer UE on a feedback resource, where the feedback includes an indication of whether there is a resource conflict.
Claims20
A method performed by a user equipment (“UE”), the method comprising:
- receiving sidelink control information (“SCI”) from a peer UE on a first resource of a physical sidelink control channel accompanied by an initial transmission of sidelink data, wherein the SCI comprises information indicating future resources reserved for future transmissions;
- determining whether there is a resource conflict, said resource conflict comprising an expected collision on the future resources;
- and
- transmitting feedback to the peer UE on a feedback resource, wherein the feedback comprises a first set of feedback resources for indicating hybrid automatic repeat request (“HARQ”) feedback and a second set of feedback resources for indicating whether there is a resource conflict.
A user equipment (“UE”) for wireless communication, comprising:
- a memory;
- and
- a processor coupled with the memory and configured to cause the UE to:
- receive sidelink control information (“SCI”) from a peer UE on a first resource of a physical sidelink control channel accompanied by an initial transmission of sidelink data, wherein the SCI comprises information indicating future resources reserved for future transmissions;
- determine whether there is a resource conflict, wherein the resource conflict comprises an expected collision on the future resources;
- and
- transmit feedback to the peer UE on a feedback resource, wherein the feedback comprises a first set of feedback resources for indicating hybrid automatic repeat request (“HARQ”) feedback and a second set of feedback resources for indicating whether there is a resource conflict.
A user equipment (“UE”) for wireless communication, comprising:
- a memory;
- and
- a processor coupled with the memory and configured to cause the UE to:
- generate sidelink control information (“SCI”) that comprises information indicating future resources reserved for future transmissions;
- transmit, to a peer UE, the SCI on a first resource of a physical sidelink control channel accompanied by an initial transmission of sidelink data;
- and
- receive feedback from the peer UE on a feedback resource, wherein the feedback comprises a first set of feedback resources for indicating hybrid automatic repeat request (“HARQ”) feedback and a second set of feedback resources for indicating whether there is a resource conflict, said resource conflict comprising an expected collision on the future resources.
