Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform, during at least a portion of a sensing window, a sensing process to identify a quantity of resources of a sidelink channel that are available for transmission by the UE during a selection window. The UE may terminate the sensing process before expiry of the sensing window based on the quantity of resources satisfying an early termination threshold. The UE may then transmit, during the selection window, a set of data over the sidelink channel using the quantity of resources.
Claims26
A method for wireless communication at a user equipment (UE), comprising:
- performing, during at least a portion of a sensing window, a sensing process to identify a quantity of resources of a sidelink channel that are available for transmission by the UE during a selection window, the sensing window comprising a plurality of contiguous time slots;
- terminating the sensing process partway through the sensing window based at least in part on the quantity of resources satisfying a threshold quantity of resources indicated by an early termination threshold, wherein the sensing window is determined before performing the sensing process, and wherein the early termination threshold is based at least in part on a second quantity of resources that is associated with a transport block size for a set of data scaled by a reliability factor;
- and
- transmitting, during the selection window, the set of data over the sidelink channel using the quantity of resources.
A method for wireless communication at a wireless device, comprising:
- receiving operating information from a user equipment (UE) engaged in sidelink communications over a sidelink channel;
- and
- transmitting, to the UE, a reliability factor for the UE to use as a basis for an early termination threshold for terminating a sensing process for the sidelink channel, wherein the reliability factor is determined based at least in part on the operating information received from the UE, and wherein the early termination threshold is based at least in part on a quantity of resources that is associated with a transport block size for a set of data to be transmitted by the UE scaled by the reliability factor.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- perform, during at least a portion of a sensing window, a sensing process to identify a quantity of resources of a sidelink channel that are available for transmission by the UE during a selection window, the sensing window comprising a plurality of contiguous time slots;
- terminate the sensing process partway through the sensing window based at least in part on the quantity of resources satisfying a threshold quantity of resources indicated by an early termination threshold, wherein the sensing window is determined before performing the sensing process, and wherein the early termination threshold is based at least in part on a second quantity of resources that is associated with a transport block size for a set of data scaled by a reliability factor;
- and
- transmit, during the selection window, the set of data over the sidelink channel using the quantity of resources.
