Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a user equipment (UE) with a first-active bandwidth part (BWP). The first-active BWP may correspond to a subset of a channel bandwidth. Retuning one or more components (e.g., radio frequency (RF) components) to the first-active BWP at the UE may involve a relatively significant delay. To avoid missing communications while tuning to the first-active BWP, the UE may initially tune to the channel bandwidth. The UE may identify a next-available time resource for retuning to the first-active BWP, where the next-available time resource may be a portion of an off-duration of a discontinuous reception (DRX) cycle or a portion of a measurement gap. The UE may use the time resource to retune to the first-active BWP while the UE is configured to reduce communications with a serving base station.

Abstract: Wireless communications apparatus and methods configured to facilitate efficient cell reselection by a user equipment camped on a serving cell of a 5G new radio base station in a panic mode are provided. Aspects of the present disclosure include limiting the number of beams of a neighboring cell that may be measured as part of a cell reselection evaluation process to determine whether the neighboring cell is a suitable cell on which the user equipment can camp.
