Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a resource is available for use by one or more other UEs. The UE may transmit a device-to-device coordination message to indicate whether the resource is available for use by the one or more other UEs. Numerous other aspects are provided.
Claims30
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive information associated with a device-to-device coordination message to indicate whether a resource is available for use by one or more UEs;
- and
- transmit the device-to-device coordination message to indicate whether the resource is available for use by the one or more UEs, wherein the device-to-device coordination message includes a bit indicator indicating whether the resource is at least one of:
- available to a UE that requested transmission of the device-to-device coordination message,
- available to the UE that requested transmission of the device-to-device coordination message and subject to resource reservation by another UE,
- available to any UE, or
- unavailable to any UE except the UE that requested transmission of the device-to-device coordination message.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a UE-common device-to-device coordination message transmitted to a plurality of UEs;
- and
- communicate on an available resource identified by a content of the UE-common device-to-device coordination message and identified by whether the UE attempted to reserve the resource.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a device-to-device coordination message indicating whether a resource is available for use by one or more UEs, wherein the device-to-device coordination message includes a bit indicator indicating whether the resource is at least one of:
- available to a UE that requested transmission of the device-to-device coordination message,
- available to the UE that requested transmission of the device-to-device coordination message and subject to another resource reservation by another UE,
- available to any UE, or
- unavailable to any UE except the UE that requested transmission of the device-to-device coordination message;
- and
- communicate on an available resource identified by the device-to-device coordination message.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a device-to-device coordination message indicating whether a resource is available for use by one or more UEs;
- and
- communicate on an available resource identified in the device-to-device coordination message, wherein the available resource is associated with a prioritization relative to one or more other available resources identified in the device-to-device coordination message.
A base station for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive first signaling identifying a user equipment (UE) as configured for device-to-device communication;
- and
- transmit second signaling indicating a configuration for a device-to-device coordination message associated with an identification of available resources for device-to-device communication.
