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: Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.

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: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for uplink switching for enhanced mobility. In some aspects, this disclosure provides techniques for potentially reducing or eliminating service interruptions experienced during a handover from a source cell to a target cell. Additionally, this disclosure provides techniques for potentially simplifying or improving uplink communications while a UE is connected to both the source cell and the target cell during the handover. This disclosure further provides techniques for potentially reducing UE power consumption or improving uplink resource utilization during a handover from a source cell to a target cell while a UE is connected to both the source cell and the target cell during the handover.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: The disclosure relates to determining priority access with dual access barring classes. An aspect receives, at a client device, at least one high priority access barring class and at least one low priority access barring class, switches to the low priority access barring class, receives an access barring message, and switches to the high priority access barring class in response to receiving the access barring message. An aspect receives a call request for a high priority call among a group of client devices, transmits a notification to a network instructing it to transmit an access barring message in response to receiving the call request, wherein one or more members of the group of client devices switch to a high priority access class in response to receiving the access barring message, and suppresses call announcements for non-priority call requests after transmitting the notification.

Abstract: In an embodiment, an apparatus (e.g., a client device, an eNodeB, MME, S-GW, P-GW, UTRAN component, etc.) detects a first transition of a client device from an active state to an idle state while the client device is allocated a Quality of Service (QoS) link by a serving network. The apparatus caches QoS information associated with the QoS link, and releases the QoS link in response to the detection of the first transition. The apparatus later detects, after the caching and releasing, a second transition of the client device from the idle state back to the active state. The apparatus re-establishes the QoS link in response to the detection of the second transition using the cached QoS information.

Abstract: In an embodiment, an apparatus monitors traffic usage in uplink and downlink directions of a link that is configured to support a communication session for the client device. The apparatus can correspond to a core network component or to an access network component. The apparatus initiates, in association with the communication session, (i) an uplink-specific QoS adjustment to a first level of QoS assigned to the uplink direction of the link based on the monitored traffic usage in the uplink direction, and/or (ii) a downlink-specific QoS adjustment to a second level of QoS assigned to the downlink direction of the link based on the monitored traffic usage in the downlink direction. The link is maintained in both the downlink and uplink directions throughout the communication session irrespective of any QoS adjustments in the uplink and/or downlink directions of the link that occur during the communication session.

Abstract: The disclosure relates to optimistic QoS setup. A network element receives an IP packet that is not associated with a QoS request on a bearer for an application/service executing on a target client device, and initiates QoS activation for the target client device based on a combination of an application-specific identifier from the target client device and a user-specific identifier of the application/service. A server receives a session setup request that is not associated with a QoS request for an application/service executing on a target client device, the session setup request identifying one or more client devices to participate in a session, and initiates QoS activation for at least one of the client devices, before a session announcement is transmitted to the client devices, based on a combination of an application-specific identifier from the target client device and a user-specific identifier of the application/service.
