A UE or a network may be capable of obtaining location-specific cell coverage information from an external source (such as a coverage map or a database). The network may use the coverage information to configure a measurement gap for the UE. For example, the UE may be located in a cell with relatively high coverage quality compared to that of a neighboring cell, according to the external source. Based on the relative coverage quality, the network may reduce the periodicity of the UE measurements, change the measurement gap to be aperiodic, or configure the UE to refrain from measuring. ## Claims ### Claim 1 A user equipment (UE), comprising: one or more memories storing processor-executable code;
