Systems, methods, and tools may schedule protocol data unit (PDU) sets. A wireless transmit receive (WTRU) may receive configuration information, including a delay threshold and a configured grant (CG) arrangement, from a network node. The WTRU may receive a first PDU subset and related information from an application. The WTRU may estimate the payload size and arrival time of a second PDU subset. Based on the estimates and the payload size of the first subset, the WTRU may determine the first and second groups of CG PUSCH occasions. If the estimated arrival time difference between the two subsets is larger than the delay threshold, the WTRU may identify an available CG PUSCH occasion. The information may be sent to the network node.

This disclosure provides methods, components, devices and systems for multi-layer signaling for ambient power (AMP) devices. Some aspects enable early differentiation between non-backscatter AMP device types through signaling in AMP downlink physical layer protocol data units (PPDUs). For example, a wireless device receives a first portion of an AMP downlink PPDU indicating an intended STA type (such as an active transmitter or an AMP-enabled device) and selectively receives subsequent portions of the AMP downlink PPDU in accordance with whether the type of the wireless device matches the indicated type. In scenarios in which the types match, the wireless device continues receiving the PPDU. Otherwise, the wireless device ceases reception to conserve energy and processing resources. The first portion may include one or more fields that indicate the intended STA type, may indicate a medium access control (MAC) frame type that implicitly indicates the intended STA type, or both.
