The UE may transmit the grant delay request as part of a scheduling request (SR), or as part of a buffer status report (BSR), or a combination of these.

Abstract: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for layer 2 relay user equipment (UE) mobility. A relay UE relays data between a first network entity and a remote UE based on a first configuration of the remote UE. The relay UE may receive, from the first network entity on a first connection, a handover request that includes a second configuration for a second network entity or a third configuration for the remote UE. The relay UE determines whether dual active protocol stack radio link control channels are configured for the remote UE based on the first configuration or the third configuration. The relay UE establishes a second connection with the second network entity based on the second configuration, and transmits, to the remote UE, a handover status indicating a result of establishing the second connection with the second network entity.

An example method for relay reselection triggering by a relay user equipment (UE) generally includes detecting a radio link failure (RLF) on at least one of a first link between the relay UE and a serving network entity or a second link between the relay UE and a remote UE and taking one or more actions, in response to the detection, to trigger relay reselection by the remote UE.

Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support multi-secondary cell group configurations. Generally, the described techniques provide for a configuration that enables a user equipment (UE) to perform multiple conditional primary and secondary cell (PSCell) addition or change procedures. For instance, the UE may perform a series of conditional PSCell changes and/or conditional PSCell additions based on a single configuration provided by a network entity. In such cases, the single configuration may be based on a subset of secondary nodes (secondary nodes) that are identified by one or more target secondary nodes. In some aspects, the single configuration may include an indication that the configuration may be used for multiple PSCell changes or additions, and the UE may store the configuration based on the indication.

Abstract: Aspects of the present disclosure provide techniques for configuring and triggering conditional handover for UE mobility between a direct connection to the base station (Uu connection) and/or a relay connection (PC5 connection). Specifically, the conditional handover configuration may include preparing multiple candidate relay UEs for handover (e.g., from Uu connection to PC5 connection) and conditional handover execution criteria for relay selection (or reselection) for the UE. Similarly, features of the present disclosure provide techniques for conditional handover transition from a PC5 connection back to Uu connection when conditional handover execution criteria are met (e.g., sidelink signal strength between the two UEs falls below a channel condition threshold). Additionally, the techniques provided herein support for conditional handover of the relay UEs from a first base station to a second station while the relay UE is further supporting one or more remote UEs.

Abstract: Aspects relate to coordination of communication links associated with multiple subscriptions. For example, a base station may determine that a first communication link and a second communication link are established with a user equipment (UE) using a first subscription and a second subscription of the UE, respectively. At least one of the first communication link or the second communication link may be established between the UE and the base station. The base station may coordinate communication of information with the UE via at least one of the first communication link or the second communication link based on the determination. The base station may coordinate the communication of information by selecting, based on the information, one of: the first communication link and the second communication link for communicating the information, or the first communication link or the second communication link for communicating the information without utilizing the other communication link.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a relay user equipment (UE) establishes a sidelink with a remote UE to provide one or more UE-to-network relay services to the remote UE, monitors paging occasions (POs) in a first bandwidth part (BWP), receives a page from a serving base station during a PO in the first BWP, and forwards the page to the remote UE over the sidelink in an initial sidelink BWP. In another aspect, the relay UE receives downlink control information (DCI) from a serving base station for a downlink grant for the remote UE, receives downlink data for the remote UE from the serving base station, transmits sidelink control information (SCI) instructing the remote UE to switch from a first sidelink BWP to a second sidelink BWP, and forwards the downlink data to the remote UE over the second sidelink BWP of the sidelink.

Abstract: A first network node may transmit, to a second network node, first information associated with granular user consent control. The first information may be further associated with a data processing task and a UE. The second network node may receive, from the first network node or the UE, second information associated with the granular user consent control. The second information may be further associated with the data processing task and the UE. The second network node may identify a user consent result associated with the data processing task and a user of the UE based on the granular user consent control. The user consent result may be further based on the first information or the second information. The second network node may transmit, to the first network node, the user consent result. Thereafter, the first network node may handle the data processing task based on the user consent result.

The client device context may include network state information for the client device that enables the network to communicate with the client device. The client device may obtain, from a network device that serves a first service area of the network, information that includes a first client device context. The client device may enter a second service area of the network served by a second network device. Instead of performing a service area update procedure with the network, the client device may transmit a packet in the different service area with the information that includes the client device context. The client device may receive a service relocation message including information associated with the different network device in response to the transmission.
