Abstract: Various aspects of the present disclosure relate to a user equipment (UE) that acquires a channel occupancy time (COT) for part of an unlicensed spectrum, allowing the acquiring UE to transmit sidelink (SL) control and data information to a secondary UE, and furthermore share the COT with the secondary UE. Sharing the COT with the secondary UE allows the secondary UE to transmit SL control and data to the acquiring UE or another UE. To initiate COT sharing, the UE that acquires the COT transmits a COT sharing indicator to one or more destination identifiers (IDs), notifying one or more secondary UEs of the COT sharing. The COT sharing indicator may include any of various information, such as remaining channel occupancy duration, priority, one or more destination IDs, offset indicating when the COT sharing may be transmitted, one or more resource pool IDs, and so forth.

The UE includes a transceiver including a main radio and a low power wake-up radio, at least one memory, and at least one processor coupled to the transceiver and the at least one memory. The at least one processor is configured to cause the UE to, in response to configuring use of the low-power wake-up radio of the transceiver, initiate monitoring of a downlink from a network equipment for a low-power wake-up signal using the low power radio.

The UE is configured to identify from the wake-up indication whether the main radio (MR) needs to be woken up, and to identify from the LP-WUS whether channel state information needs to be reported, based at least on one or more channel state information reporting conditions and/or configurations.
