Abstract: In order to improve efficiency in releasing a connection with a user equipment, a method, apparatus, and computer-readable medium are presented herein. A RAN receives release assistance information from a user equipment or a User Plane Function (UPF) involved in an active session with the user equipment. The release assistance information may be received over a control plane or over a user plane. The release assistance information may be received from the user equipment or the UPF over the user plane or as Radio Resource Control (RRC) signaling. The release assistance information may be received from an application function via the UPF. The RAN determines to release the user equipment based on the release assistance information.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication includes determining, by a user equipment (UE), a minimization of drive test (MDT) result and determining, by the UE, an early measurement result. The method further includes transmitting, by the UE, a report including the MDT result, the early measurement result, or a combination thereof. Other aspects and features are also claimed and described.

Abstract: An apparatus for wireless communication, including a memory and at least one processor coupled to the memory. The at least one processor is configured to receive a pre-allocation resource for a target cell via a handover command and transmit a physical layer acknowledgment based on a target cell downlink packet. The at least one processor is also configured to receive an indication for a communication with the target cell in response to the physical layer acknowledgement and access the target cell using the pre-allocated resource based on the indication for the communication with the target cell.

Abstract: Wireless communications systems as described herein may be configured to provide user equipment (UE) assisted information for caching data at a network node external to a core network (CN). In some cases, the UE may provide an acceleration indicator (AI) that a base station may receive and identify as caching information. The base station, upon identifying that the AI is present in an uplink packet, may transmit the packet to a gateway having a local cache. If the uplink packet does not have an AI, the base station may route the uplink packet according to an address (e.g., a uniform resource locator (URL)) contained in the packet.

Abstract: Systems and techniques are disclosed to reduce workload on base stations in a mobile network when content delivery networks cache content inside the network. A user equipment sets a flag only with those packets on the uplink which include requests that should be routed to the cache server inside the mobile network. The base stations perform deep packet inspection of those packets where flags have been set and forward other packets on to the rest of the relevant backhaul of the mobile network. After deep packet inspection, the base stations either route the packet to the cache server via an established connection or propagate the flag in an extension header to another network node for routing to the cache server. The resulting content is returned to the UE with the source address of the originally intended destination instead of the cache server, rendering the process transparent to the end user.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently collecting and reporting minimization of drive test (MDT) measurements for one or more radio access technology (RAT) types and/or for multiple base stations in a dual connectivity deployment. In one example, a user equipment (UE) may receive an MDT measurement configuration indicating a first RAT type for collecting measurements and a second RAT type for reporting measurements. In this example, the UE may use the measurement configuration to collect MDT measurements for the first RAT type, and the UE may report the MDT measurements to a base station associated with the second RAT. Further techniques for efficiently collecting and reporting MDT measurements in a dual connectivity deployment are also described herein.

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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that improve data packet exchange between a UE in an inactive mode and a network. In certain configurations, the apparatus may receive, from a user equipment (UE) in an active mode, a first packet including a first identifier associated with an anchor base station, a second identifier associated with a UE context, and a payload. The apparatus may identify the anchor base station based at least in part on one or more of the first identifier associated with the anchor base station or the second identifier associated with the UE context. The apparatus may transmit a second packet to the anchor base station. The second packet may include at least a portion of the first packet.
