Method and apparatus for nr v2x resource selection

A second user equipment (UE) in a wireless communication system, the second UE comprising:

• a transceiver configured to:
• transmit, to a first UE via a sidelink, signals including information to select resources for at least one of aperiodic traffic or periodic traffic,
• receive, from the first UE, the at least one of aperiodic traffic or periodic traffic using resources,
• wherein:
• sidelink control information (SCI) from the information included in the signals is decoded,
• a signal measurement of the transmitted signals, over a sensing window, is performed,
• a resource selection window is identified based on a latency requirement, and
• the resources are reserved for the at least one of aperiodic traffic or periodic traffic in a frequency domain and a time domain based on the decoded SCI and a result of the signal measurement, the resources being identified within a resource selection window.

A method of a first user equipment (UE) in a wireless communication system, the method comprising:

• receiving, from a second UE via a sidelink, signals including information to select resources for at least one of aperiodic traffic or periodic traffic;
• decoding sidelink control information (SCI) from the information included in the signals;
• performing, over a sensing window, a signal measurement of the received signals;
• identifying a resource selection window based on a latency requirement;
• reserving the resources for the at least one of aperiodic traffic or periodic traffic in a frequency domain and a time domain based on the decoded SCI and a result of the signal measurement, the resources being identified within a resource selection window;
• and
• transmitting, to the second UE via the sidelink, the at least one of aperiodic traffic or periodic traffic using the reserved resources.
