In some aspects, SCI transmitted by a UE 120 (e.g., the first UE 120 and/or the second UE 120) may reserve aperiodic (e.g., dynamic) resources or periodic resources. For example, the SCI may reserve resources that repeat with a configured periodicity. In some aspects, a periodicity for periodic sidelink resources may have a value between 0 milliseconds and 1000 milliseconds, among other examples. In some aspects, UEs 120 may be enabled and/or prevented from reserving periodic resources on a sidelink channel by a configuration.
As indicated above, FIG. 5 is provided as an example. Other examples may differ from what is described with respect to FIG. 5.
FIG. 6 is a diagram illustrating an example 600 of resource selection for sidelink communications, in accordance with the present disclosure. As shown in FIG. 6, a UE 120 may use a channel sensing procedure to select resources for sidelink communication, such as described above in connection with FIG. 3.
As shown in FIG. 6, a UE 120 may perform a channel sensing procedure in a sensing window 605. In some cases, the sensing window may be 100 milliseconds (e.g., for aperiodic resource reservation, such as aperiodic reservation in one or more slots of up to 32 logical slots in the future) or 1100 milliseconds (e.g., for periodic resource reservation). In some cases, a UE 120 configured for communication in an NR network may use a sensing procedure for aperiodic or periodic resource reservation.
