Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a packet at a transmitter of the UE for transmission in a sidelink network. The UE may select one or more resources for transmission of the packet based at least in part on a reservation status of the one or more resources, wherein at least one of the one or more resources is a reserved resource that is reserved by another UE. The UE may transmit the packet using the one or more resources based at least in part on selecting the one or more resources. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a packet at a transmitter of the UE for transmission in a sidelink network;
- attempting to select one or more resources for transmission of the packet based at least in part on a resource reservation associated with another UE reserving at least one resource of the one or more resources,
- wherein the UE attempts to select the one or more resources in a particular transmission time interval (TTI) based at least in part on:
- the UE previously attempting to select the one or more resources within a previous TTI, and a threshold amount of resources not selectable within the previous TTI, or
- wherein the UE attempts to select the one or more resources when sweeping a contention window within a packet delay budget (PDB) based at least in part on:
- the UE previously attempting to select the one or more resources within the contention window and the PDB, and the threshold amount of resources not selectable within the contention window and the PDB;
- and
- transmitting the packet using the one or more resources based at least in part on selecting the one or more resources based at least in part on attempting to select the one or more resources.
5 more elements
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive a packet at a transmitter of the UE for transmission in a sidelink network;
- attempt to select one or more resources for transmission of the packet based at least in part on a resource reservation associated with another UE reserving at least one resource of the one or more resources,
- wherein the UE attempts to select the one or more resources in a particular transmission time interval (TTI) based at least in part on:
- the UE previously attempting to select the one or more resources within a previous TTI, and a threshold amount of resources not selectable within the previous TTI, or
- wherein the UE attempts to select the one or more resources when sweeping a contention window within a packet delay budget (PDB) based at least in part on:
- the UE previously attempting to select the one or more resources within the contention window and the PDB, and the threshold amount of resources not selectable within the contention window and the PDB;
- and
- transmit the packet using the one or more resources based at least in part on selecting the one or more resources based at least in part on attempting to select the one or more resources.
8 more elements
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
- receive a packet at a transmitter of the UE for transmission in a sidelink network;
- attempt to select one or more resources for transmission of the packet based at least in part on a resource reservation associated with another UE reserving one resource of the one or more resources,
- wherein the UE attempts to select the one or more resources in a particular transmission time interval (TTI) based at least in part on:
- the UE previously attempting to select the one or more resources within a previous TTI, and a threshold amount of resources not selectable within the previous TTI, or
- wherein the UE attempts to select the one or more resources when sweeping a contention window within a packet delay budget (PDB) based at least in part on:
- the UE previously attempting to select the one or more resources within the contention window and the PDB, and the threshold amount of resources not selectable within the contention window and the PDB;
- and
- transmit the packet using the one or more resources based at least in part on selecting the one or more resources based at least in part on attempting to select the one or more resources.
6 more elements
An apparatus for wireless communication, comprising:
- means for receiving a packet at a transmitter of the apparatus for transmission in a sidelink network;
- means for attempting to select one or more resources for transmission of the packet based at least in part on a resource reservation associated with another apparatus reserving one resource of the one or more resources,
- wherein the apparatus attempts to select the one or more resources in a particular transmission time interval (TTI) based at least in part on:
- the UE previously attempting to select the one or more resources within a previous TTI, and a threshold amount of resources not selectable within the previous TTI, or
- wherein the UE attempts to select the one or more resources when sweeping a contention window within a packet delay budget (PDB) based at least in part on:
- the UE previously attempting to select the one or more resources within the contention window and the PDB, and the threshold amount of resources not selectable within the contention window and the PDB;
- and
- means for transmitting the packet using the one or more resources based at least in part on selecting the one or more resources based at least in part on attempting to select the one or more resources.
