Abstract: Aspects of the disclosure relate to a UE and a network device for wireless communication. The UE sends an indication to a network device indicating a capability of receiving a PWS signal and/or a delay requirement for receiving the PWS signal. The UE receives, from the network device, a configured DRX cycle value associated with the indication and a paging signal corresponding to the PWS signal associated with the configured DRX cycle value. The network device determines whether the UE is capable of receiving the PWS signal and whether the UE desires to receive the PWS signal within a duration. The network device configures a DRX cycle value based on the determination and sends, to the UE, the configured DRX cycle value and a paging signal corresponding to the PWS signal based on the configured DRX cycle value. Other aspects, features, and embodiments are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication in a multi-connectivity user equipment (UE) are described. The UE may communicate with one or more base stations via a first radio access technology (RAT). The UE may determine whether the UE is in a selected state. The selected state may correspond to one or more modes of operation (e.g., a doze mode, a relaxed doze mode, an active WiFi communication mode, a low battery mode). The UE may disable communication via a second RAT in response to determining that the UE is in the selected state. The UE may continue to communicate via the first RAT.

Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

Abstract: A method for communication includes obtaining a timing signal from a timing synchronization reference source, computing a system frame number (SFN)-direct frame number (DFN) offset, creating a timing fingerprint using the timing signal and the SFN-DFN offset, the timing fingerprint also comprising additional timing information, entering the timing fingerprint into a database, continually updating the timing fingerprint, determining whether the timing signal remains within a threshold, if the timing signal exceeds the threshold, iterating the timing fingerprint, verifying the timing fingerprint to determine whether there is a timing inconsistency between a most recent timing fingerprint and current time, if the timing fingerprint is verified, using the SFN-DFN offset to derive current DFN timing to decode a sidelink control information (SCI) communication, and if the SCI communication is decoded, using the timing signal for communicating over a sidelink communication channel.

Abstract: Aspects of the present disclosure relate to receiver beamforming for serving and neighbor cell measurements. An exemplary method generally includes communicating with one or more base stations using a first beam type, initiating a transition to communicating with at least one of the one or more base stations using a second beam type in response to an indication of a trigger event, and communicating with the at least one of the one or more base stations using the second beam type.

Abstract: Certain aspects of the present disclosure generally relate to enhanced procedures for search, measurement, and positioning with aid of motion detection information. According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a user equipment (UE). The method generally includes determining one or more parameters of the UE; dynamically adjusting a periodicity of at least one of: cell search and measurements or global positioning system (GPS) signal acquisition based, at least in part, on the one or more parameters; and performing at least one of: the cell search and measurements or GPS signal acquisition according to the adjusted periodicity. In aspects, an enhanced technique for motion state detection is provided. The method may result in power savings, for example, when the UE is stationary and can reduce the periodicity that the UE performs search, measurement and GPS signal acquisition.
