Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for maintaining simultaneous connection with a network in dual-active protocol stack (DAPS) handover (HO), such as, for example, in packet data convergence protocol (PDCP) duplication applications that require a user equipment (UE) to maintain up to four simultaneous connections with the network, such as in an multi-radio access transfer (RAT) dual connectivity (MR-DC) to MR-DC HO. In some embodiments, the UE is configured during various phases of a DAPS HO. In some other embodiments, the UE may be configured for multi-TRP operations.

Abstract: A user equipment (UE) establishes a unicast link with a second UE, including establishing an authentication and security establishment procedure between the first UE and the second UE. The UE establishes a security context with the second UE during the authentication and security establishment procedure. The UE starts a timer based on a status of the unicast link. The UE reestablishes the unicast link with the second UE using the security context when the unicast link is reestablished prior to expiration of the timer.

Abstract: Aspects of this disclosure relate generally to mobility in a service-based architecture. Some aspects more specifically relate to path switching in a service-based architecture. In some examples, a distributed node may exchange signaling with a service server to configure and execute a path switch in connection with handover of a user equipment to the distributed node. For example, the distributed node may communicate with the service server directly. As another example, the distributed node may communicate with a mobility service to execute the path switch. In some examples, aspects described herein provide for a service server to buffer data and provide data forwarding in connection with the path switch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that includes trigger information for generating a measurement report for one or more candidate secondary cells after receiving an activation command that activates a secondary cell for which the UE has not reported measurements. The UE may receive the activation command. The UE may transmit the measurement report based at least in part on the activation command and the trigger information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may operate, in connection with a secondary cell group (SCG) for multiple radio access technology dual connectivity, in one of an SCG dormant state in a dormant downlink bandwidth part (BWP) configured for a primary secondary cell of the SCG or an SCG enhanced dormant state in an enhanced dormant downlink BWP configured for the primary secondary cell. The UE may receive a control message associated with activating the SCG for the UE, the control message indicating a BWP switch for the UE. The UE may switch, in connection with receiving the control message, from one of the dormant downlink BWP or the enhanced dormant downlink BWP to an activated downlink BWP in which the UE operates in an SCG activated state. Numerous other aspects are provided.

Abstract: A UE receives a first primary cell group (MCG) configuration and a first secondary cell group (SCG) configuration; and receives a set of conditional secondary cell group (SCG) configurations, each conditional SCG configuration including a set of candidate target primary secondary cells (PSCells), corresponding PSCell change execution conditions, and corresponding SCG configurations. The UE communicates with a network, in response to an PSCell change execution condition corresponding to a first PSCell being satisfied, based on the first MCG configuration, the first SCG configuration, and an SCG configuration corresponding to the first PSCell.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for radio link failure recovery and beam failure recovery on a secondary cell group (SCG) in dormancy state. In an example, a user equipment (UE) may determine the UE has entered a dormant state with respect to the SCG of a secondary node (SN) having a primary SCG cell (PSCell). The UE may monitor the PSCell to detect a beam failure or a radio link failure while the UE is in the dormant state with respect to the SCG. The UE may transmit, to the SN, a report based on the beam failure or the radio link failure on the PSCell being detected.

Abstract: A configuration to enable a UE to monitor the state of the connection with a peer UE in a sidelink communication. The apparatus establishes one or more unicast links with a second UE. The apparatus changes a connection state with the second UE from a sidelink disconnected state to a sidelink connected state based on an establishment of a first of the one or more unicast links. The apparatus changes the connection state with the second UE from the sidelink connected state to the sidelink disconnected state when each of the one or more unicast links with the second UE is released or when a configured timer expires.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for a nested conditional mobility procedure. In some cases, a method for wireless communications by a UE generally includes receiving configuration information configuring the UE for conditional handover (CHO) from a source master node (S-MN) to a target master node (T-MN) and for conditional primary secondary cell (PSCell) addition or change (CPAC) and performing a nested procedure based on an evaluation of conditions for both CHO and CPAAC in accordance with the configuration information.
