Abstract: A wireless station (STA) in a wireless local area network (WLAN) performs a method to avoid media access control (MAC) padding of a physical layer convergence protocol data unit (PPDU) (e.g., a trigger-based (TB) PPDU, etc.). The method can reduce current or power consumption by the STA, which can in turn optimize the STA and, in certain instances, the WLAN as whole. In one example, the method includes the STA receiving a trigger frame from an access point (AP). The trigger frame specifies a length of a PPDU. The method further includes the STA generating a TB PPDU based on the specifications in the trigger frame. In particular, the STA generates a PPDU that has a length that is less than the length specified by the trigger frame. The method also includes the STA transmitting the generated PPDU to the AP.

Abstract: A wireless transmit/receive unit (WTRU) operating in an autonomous-scheduled mode may select a first resource from a resource pool. The WTRU may determine that the first resource is reserved for at least one sidelink transmission scheduled via a network-scheduled mode. The WTRU may evaluate the availability of resources in the resource pool based on determining that the first resource is reserved for the sidelink transmission. The WTRU may determine that a resource is available based on a measurement comparison to one or more thresholds. For example, there may be a first threshold for resources reserved by WTRUs operating using the network-scheduled mode and a second threshold for resources reserved by WTRUs operating using the autonomous-scheduled mode. The first threshold may be determined based on the second threshold and an offset value. The WTRU may reselect to a second resource in the resource pool based on the evaluated resource availability.
