Abstract: Methods, systems, and devices are described for enhanced power savings in wireless devices through mobile initiated dormancy procedure. A user equipment (UE) may establish radio resource control (RRC) connectivity with a base station of the network, and transmit and receive one or more distinct signaling messages for dormancy state initialization and suspension at the UE. Dormancy state implementation at the UE may conserve available power resources at the UE during periods of inactive data transaction. The one or more signaling messages may contain a single or multi-bit indication for the receiving device, and may be transmitted via direct signaling on upper layer protocols of the data network or mapped to allocated resources of a data transmission. The signaling messages may sustain synchronization between the interpreted functional mode of the UE at the base station and the implemented mode at the UE.

Abstract: Capability exchange enhancements include filtering and/or indexing. In some aspects, a user equipment (UE) determines UE capabilities to be reported to a network based on one or more of: one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type. In other aspects, a UE may report a subset of UE capabilities for features used for the connection establishment. Following connection establishment, the UE may use an identifier to communicate a more complete set of modes of operation that the UE is currently capable of performing. Base stations of the network may share the reported subset so that the UE may avoid transmitting the subset to a target base station.

Abstract: Methods and apparatus for selection of radio access technology (RAT) based on device usage patterns are provided. A User Equipment (UE) obtains information relating to one or more Quality of Service (QoS) metrics for communication of data by the UE. The UE designates a Radio Access Technology (RAT) from a plurality of available RATs as a preferred RAT for the communication, based on the obtained information.

Abstract: Certain aspects of the present disclosure provide techniques for supporting a connected mode enhanced pruning procedure. A UE may select, while operating in connected mode with a first radio access technology (RAT), measurement candidates for a potential handover based on one or more criteria, maintain an active list including the selected measurement candidates, perform at least one measurement based, at least in part, on the active list, and take one or more actions based, at least in part, on the at least one measurement.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine whether at least one frequency band, designated for device-to-device communication of the user equipment, is associated with an active SCC of the user equipment; and selectively perform the device-to-device communication using a particular communication chain of the user equipment based at least in part on whether the at least one frequency band is associated with the active SCC, wherein the particular communication chain is tuned to the at least one frequency band for communication using the active SCC. Numerous other aspects are provided.

Abstract: Examples described herein relate to systems and methods for a wireless communication device to manage cell measurements, including, but not limited to, performing measurements based on a first measurement configuration message received from a network, receiving a second measurement configuration message from the network before the measurements based on the first measurement configuration message are completed, and continuing to perform measurements based on the first measurement configuration message after receiving the second measurement configuration message.

Abstract: A method and apparatus for efficiently performing measurements during a connected mode in a wireless communication system is disclosed. For example, the method and apparatus may include receiving, at a user equipment (UE), a Radio Resource Control (RRC) Reconfiguration message including a plurality of measurement objects from a network entity to identify frequencies during a measurement procedure; receiving, at the UE, one or more neighbor discovery expression messages, each neighbor discovery expression message including a neighbor measurement object and being received from a respective neighbor UE; determining, by the UE, whether the plurality of measurement objects of the RRC Reconfiguration message satisfy a measurement capability threshold; selecting, by the UE, a portion of the plurality of measurement objects of the RRC Reconfiguration message; and performing, by the UE, the measurement procedure for each measurement object of the portion of the plurality of measurement objects.
