Claims:1. One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed cause a user equipment (UE) to:
sense for activity on a sidelink channel within a configurable sensing window duration;
select sidelink resources of the sidelink channel to use for a sidelink transmission, the sidelink transmission including an initial transmission and re-transmissions of a sidelink message including one or more transport blocks (TBs); and
encode, for transmission on a physical sidelink control channel (PSCCH), a sidelink control information (SCI) that includes resource reservation information to indicate the selected sidelink resources are reserved for subsequent transmissions or re-transmissions of the one or more TBs.
, Description:FIELD
[0002] Embodiments of the present invention relate generally to the technical field of wireless communications.

BACKGROUND
[0003] The design for Long Term Evolution (LTE) vehicle-to-vehicle (V2V) communication was based on the assumption of periodic broadcast traffic. Based on this assumption, the UE made semi-persistent decision on selected resources for V2V transmissions. The LTE V2V design was not optimized for aperiodic traffic with large variations in packet arrival times and packet payload sizes.

BRIEF DESCRIPTION OF THE DRAWINGS
[0004] Embodiments will be readily understood by the following detailed description in ?conjunction with the accompanying drawings. To facilitate this description, like reference ?numerals designate like structural elements. Embodiments are illustrated by way of example and ?not by way of limitation in the figures of the accompanying drawings.?
[0005] Figure 1A illustrates a sensing scheme including a long-term sensing window and a short-term sensing window, for the case when no collision is detected within the short-term sensing window with respect to the selected candidate resources for sidelink transmission, in accordance with various embodiments.
[0006] Figure 1B illustrates the sensing scheme when a collision is detected within the short-term sensing window, and the initially selected candidate resources need to be adjusted (reselected), in accordance with various embodiments.
