Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and/or a master node may use configurations to resume communications with one or more cells of a dual connectivity (DC) or carrier aggregation (CA) scheme. In some cases, the configuration may be used for a secondary cell group (SCG) of the DC scheme. This configuration may include the UE applying a previously stored configuration for the SCG (e. g., including higher-layer and lower-layer configurations of a last serving SN of the DC scheme) if it determines the previously stored configuration is valid. Additionally or alternatively, the configuration may include the network using a previous SCG configuration or reconfiguring the SCG and transmitting this indication in a resume communications message to the UE. In some cases, the network may determine this configuration based on assistance information or reports generated from the UE.

Abstract: Apparatus, methods, and computer-readable media for facilitating mobility in sidelink-assisted access link connectivity are disclosed herein. An example method for wireless communication at a user equipment (UE) includes establishing a sidelink connection with a first assistant node (AN) and establishing an access link connection with a first primary node (PN), the first AN and the first PN communicating via a first network interface. The example method also includes determining an occurrence of a node-change triggering event associated with at least one of the first AN and the first PN. The example method also includes performing a node-change procedure based on the occurrence of the node-change triggering event. The example method also includes communicating with at least one of a second AN or a second PN based on the node-change procedure, the second AN and the second PN communicating via a second network interface.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may establish a sidelink unicast link with a remote UE via a sidelink signaling interface. The relay UE may identify configuration information for an adaptation layer of the sidelink signaling interface, the configuration information including at least one of: a remote UE identifier associated with the sidelink unicast link for a relay service, bearer identifier information identifying one or more bearers between the remote UE and a network entity for the relay service, a radio link control (RLC) channel mapping between a bearer identifier and one or more RLC channels, or data routing information associated with the relay service. The relay UE may relay communications between the remote UE and the network entity based at least in part on the configuration information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) that is out-of-coverage of a base station and a second UE that is in-coverage of the base station may support signaling exchanges for transmitting or receiving a discovery message, an essential system information block (E-SIB), common SIB updates, or on-demand SIBs within a relaying network before and after a relay connection between the first UE and the second UE. The first UE may receive the discovery message and the E-SIB via same or different signaling and may acquire or decode the E-SIB according to various techniques. The first UE may receive common SIB updates via a dedicated logical channel between the first UE and the second UE and the first UE may initiate on-demand SIB acquisition after establishment of the relay connection and based on a connection type of the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first device of a wireless communications network may receive, from a second device of the wireless communications network, a configuration for a bandwidth part switching pattern for wireless communications performed at the first device, the bandwidth part switching pattern including at least a first bandwidth part and a second bandwidth part different from the first bandwidth part. The first device may transmit a first transmission to one or more devices of the wireless communications network during a first time interval and in accordance with the first bandwidth part, and may transmit a second transmission to the one or more devices of the wireless communications network during a second time interval different from the first time interval and in accordance with the second bandwidth part.

Abstract: A first wireless device establishes a first connection to a second wireless device and establishes a second connection with a network entity via the second wireless device. The first wireless device transmits a message to the network entity via the second wireless device, the message indicating that the second connection is a remote connection. The second wireless device establishes the first connection with the first wireless device to relay traffic between a network entity and the first wireless device and establishes a connection with the network entity to relay the traffic between the network entity and the first wireless device. The second wireless device receives a configuration from the network entity for the second connection between the network entity and the first wireless device for relaying the traffic to the second wireless device.

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: Certain aspects of the present disclosure provide techniques for system acquisition in sidelink relay scenarios. An example method for adaptive paging by a relay node generally includes connecting, via a sidelink, to a remote user equipment (UE) while the relay node is also connected to a network entity, receiving, from the network entity, system information block (SIB) information, and sending the SIB information to at least the remote UE.
