Partial sensing and congestion control for long term evolution (lte) vehicular communication

An apparatus configured to be employed in a user equipment (UE) to support reduced complexity and power efficiency in a sidelink communication for pedestrian to vehicle (V2P) communication, comprising:

• processing circuitry configured to:
• generate a plurality of partial sensing windows to be sensed for a resource (re)selection procedure;
• monitor one or more physical channels to detect occupied resources based on the plurality of partial sensing windows;
• generate a candidate resource set based on non-occupied resources or less congested resources determined from processing the plurality of partial sensing windows;
• and
• perform the resource (re)selection in a resource (re)selection window based on a resource (re)selection trigger and the candidate resource set;
• and
• a radio frequency (RF) interface, configured to provide, to RF circuitry, data for the pedestrian to vehicle communication based on the resource (re)selection procedure.

A computer readable storage medium storing executable instructions that, in response to execution, cause one or more processors of a user equipment to support reduced complexity and power efficiency in a sidelink communication for vehicle communication, the operations comprising:

• generating a plurality of partial sensing windows to be sensed for a resource (re)selection procedure;
• monitoring continuously one or more sidelink physical channels to detect occupied resources based on the plurality of partial sensing windows;
• generating a candidate resource set based on the one or more occupied resources or less congested resources over the plurality of partial sensing windows;
• performing the resource (re)selection procedure in a resource (re)selection window based on the candidate resource set;
• and
• generating a transmission based on selected resources from the resources (re)selection with the candidate resource set formed from a sensing procedure over the plurality of partial sensing windows.

An apparatus configured to be employed in a vehicle user equipment (V-UE) or a pedestrian user equipment (P-UE), comprising:

• a memory interface storing a candidate resource set;
• and
• processing circuitry configured to:
• determine one or more occupied resources on a plurality of channels in one or more partial sensing windows;
• generate the candidate resource set based on the one or more non-occupied resources;
• perform resource (re)selection procedure in a resource (re)selection window based on the candidate resource set;
• and
• generate a transmission based on selected resources from the resources (re)selection with the candidate resource set.
