Abstract: Aspects relate to sharing a channel occupancy time (COT) initiated by a network access node (e.g., a base station) with one or more wireless communication devices for sidelink communication between the wireless communication devices. In this example, the network access node can transmit a COT structure indication (COT-SI) to the wireless communication device(s) indicating the COT resources (e.g., time and frequency resources) of the COT that may be shared with sidelink. In some examples, the wireless communication device can receive a message from the network access node including a COT sharing indicator indicating whether COT sidelink sharing is enabled or disabled.

Abstract: Thus, aspects of the present disclosure allow for a target UE to utilize a cooperative device to communicate with a base station when the target UE is out of coverage or in poor radio connections, but can still connect to another UE over a non-3GPP technology. Aspects of the present disclosure may receive a derived radio resource control (RRC) key from a user equipment (UE) in a non-Third Generation Partnership Project (non-3GPP) link between the apparatus and the UE. In some aspects, the UE is out of coverage of a network entity in a 3GPP link with the apparatus. In another instance, aspects of the present disclosure may receive control data from the network entity in the 3GPP link using the derived RRC key. In yet another instance, aspects of the present disclosure may transmit the control data to the UE in the non-3GPP link.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include receiving, from a second network entity in RRC signaling, a set of mobility configurations, wherein each configuration of the set mobility configurations is associated with a respective cell of a mobility configured cell set, and wherein the set of mobility configurations comprises PCell configurations, wherein each PCell configuration of the PCell configurations corresponds to a respective cell in the mobility configured cell set. The example method may further include receiving, from the second network entity in DCI or a MAC-CE, mobility deconfiguration information configured to cause release of at least one subset of cells from the mobility configured cell set. The example method may further include releasing, based on the mobility deconfiguration information, the at least one subset of cells from the mobility configured cell set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicative of one or more random access channel (RACH) resources for transmitting a RACH message to maintain timing advance (TA) associated with at least one deactivated cell corresponding to a TA group. The UE may transmit a RACH message to a network node corresponding to the at least one deactivated cell, wherein the RACH message is indicative of first TA information associated with the at least one deactivated cell. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a user equipment (UE) that may receive an indication of a proximity discovery resource in a physical sidelink feedback channel (PSFCH) symbol from a network entity. The UE may transmit a proximity discovery request including the indication of the proximity discovery resource. The UE may receive a PSFCH sequence associated with the proximity discovery resource from other UEs that may respond to the proximity discovery request. The UE may transmit a bit map sequence indicative of the other UEs to the network entity. The network entity may determine a proximity between the UE and the other UEs based on the bit map sequence. The network entity may schedule the UE and the other UEs based on the proximity.
