Abstract
Resource usage information is determined at a first UE about usage of a first communication resource by other UEs based on signals received by the UE. The first communication resource is excluded from a set of candidate communication resources when the resource usage information exceeds a usage threshold. When the first communication resource is excluded, a second communication resource from the candidate communication resources remaining in the set is selected to use for a transmission by the UE.
Claims18
A method comprising:
- determining, by a first user equipment device (UE), resource usage information about usage of a first communication resource by second UEs based on signals received by the first UE, wherein the resource usage information includes a number of the second UEs using the first communication resource;
- excluding the first communication resource from a set of candidate communication resources based at least on the number of the second UEs using the first communication resource of the resource usage information exceeding a threshold number of the second UEs of a usage threshold, the threshold number being at least two;
- and
- selecting, by the first UE, when the first communication resource is excluded, a second communication resource from remaining candidate communication resources remaining in the set of candidate communication resources to use for a transmission by the first UE.
A first user equipment (UE) comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and storing instructions, that when executed by the at least one processor, cause the first UE to:
- determine resource usage information about usage of a first communication resource by second UEs based on signals received by the first UE, wherein the resource usage information includes a number of the second UEs using the first communication resource;
- exclude the first communication resource from a set of candidate communication resources based at least on the number of the second UEs using the first communication resource of the resource usage information exceeding a threshold number of the second UEs of a usage threshold, the threshold number being at least two;
- and
- select, when the first communication resource is excluded, a second communication resource from remaining candidate communication resources remaining in the set of candidate communication resources to use for a transmission by the first UE.
A non-transitory computer-readable medium having instructions stored thereon that, when executed by a first user equipment device (UE), cause the first UE to perform operations, the operations comprising:
- determining resource usage information about usage of a first communication resource by second UEs based on signals received by the first UE, wherein the resource usage information includes a number of the second UEs using the first communication resource;
- excluding the first communication resource from a set of candidate communication resources based at least on the number of the second UEs using the first communication resource of the resource usage information exceeding a threshold number of the second UEs of a usage threshold, the threshold number being at least two;
- and
- selecting when the first communication resource is excluded, a second communication resource from remaining candidate communication resources remaining in the set of candidate communication resources to use for a transmission by the first UE.
