Abstract: The present disclosure presents a method and apparatus for improved reselection during mode transitions at a user equipment (UE). For example, the disclosure presents a method for identifying that a user equipment (UE) has started switching from a first priority scheduling mode to a second priority scheduling mode while making measurements for reselection. In addition, such an example method, may include initiating a mode transition timer in response to the identification and triggering a search for one or more frequencies of the second priority scheduling mode upon expiration of the mode transition timer. As such, an improved reselection during mode transitions at UE may be achieved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is connected to a wireless network on a first carrier frequency in a first frequency range that is associated with a lower data rate than a second carrier frequency in a second frequency range. In some aspects, the first frequency range may be associated with a first version of a radio access technology (RAT) and the second frequency range may be associated with a second version of the RAT. The UE may determine a bandwidth metric associated with the first carrier frequency in the first frequency range. The UE may display a first visual indicator associated with the first version of the RAT or a second visual indicator associated with the second version of the RAT based on the bandwidth metric. Numerous other aspects are described.

Abstract: A system and method of performing a handover include detecting an out of sync event while being connected to a current cell, determining whether a measurement report time-to-trigger signal is active, sending, in response to the detection of the out of sync even and the measurement report time-to-trigger signal being active, a first new measurement report and a first special cause flag prior to a next scheduled measurement report to the communication network, receiving a first list of one or more neighboring cells suitable for a handover, identifying a first neighboring cell from the first list for the handover, and attempting to perform the handover from the current cell to the first neighboring cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to a connected state. The UE may configure, based at least in part on receiving the RRC resume message, the UE with a serving cell common configuration, associated with a serving cell of the UE, received in a system information block (SIB) associated with the serving cell. Numerous other aspects are provided.
