In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE). The method generally includes determining a scheduled occurrence of a measurement gap, wherein the UE measures neighbor cell signal strength during the measurement gap, and adjusting the measurement gap based on at least one criterion. ## Claims ### Claim 1 A method of wireless communication for a user equipment (UE), comprising: determining a scheduled occurrence of a measurement gap, wherein the UE measures neighbor cell signal strength during the measurement gap; and adjusting the measurement gap based on at least one criterion, wherein adjusting the measurement gap comprises scheduling a new measurement gap outside the scheduled occurrence of the measurement gap based at least in part on comparison of downlink signal quality with at least one threshold, and wherein the at least one criterion is based, at least in part, on a priority of subframes expected to conflict with the measurement gap. ### Claim 2 (depends on 1) The method of claim 1, wherein the UE signals to a base station information regarding an extended measurement gap. ### Claim 3 (depends on 2) The method of claim 2, wherein the information indicates an extended length of time of the measurement gap for the UE and a frequency of occurrence of the extended measurement gap among a number of measurement gaps. ### Claim 4 (depends on 2) The method of claim 2, wherein the UE, before the extended measurement gap, signals the base station that the UE will use an extended measurement gap of length L at an indicated system frame number (SFN) and subframe number (SN). ### Claim 5 (depends on 2) The method of claim 2, wherein the UE, after the extended measurement gap, signals the base station that the UE used an extended measurement gap of length L at an indicated system frame number (SFN) and subframe number (SN). ### Claim 6 (depends on 1) The method of claim 1, wherein adjusting the measurement gap further comprises extending the measurement gap, the extending the measurement gap comprising scheduling a measurement gap of length L based at least in part on a metric. ### Claim 7 (depends on 6) The method of claim 6, wherein L comprises the length of time for the scheduled measurement gap or a number of subframes for the scheduled measurement gap. ### Claim 8 (depends on 6) The method of claim 6, wherein the metric comprises serving cell carrier-to-interference-and-noise-ratio (CINR) or signal-to-interference-and-noise-ratio (SINR). ### Claim 9 (depends on 6) The method of claim 6, further comprising: measuring neighbor cell signal strength during the extended measurement gap; and terminating the extended measurement gap early based at least in part on comparing the measured neighbor cell signal strength with a threshold. ### Claim 10 (depends on 6) The method of claim 6, further comprising dynamically setting a number of cells to measure in each measurement gap. ### Claim 11 (depends on 6) The method of claim 6, further comprising performing downlink (DL) processing operations during remaining measurement gaps that are not extended. ### Claim 12 An apparatus for wireless communication at a user equipment (UE), comprising: at least one processor; and a memory coupled to the at least one processor, the memory comprising instructions executable by the at least one processor to cause the apparatus to: determine a scheduled occurrence of a measurement gap, wherein the UE measures neighbor cell signal strength during the measurement gap, and adjust the measurement gap based on at least one criterion, wherein adjusting the measurement gap comprises scheduling a new measurement gap outside the scheduled occurrence of the measurement gap based at least in part on comparison of downlink signal quality with at least one threshold, and wherein the at least one criterion is based, at least in part, on a priority of subframes expected to conflict with the measurement gap. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the UE signals to a base station information regarding an extended measurement gap. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the information indicates an extended length of time of the measurement gap for the UE and a frequency of occurrence of the extended measurement gap among a number of measurement gaps. ### Claim 15 (depends on 13) The apparatus of claim 13, wherein the memory further comprises instructions executable by the at least one processor to cause the apparatus to: before the extended measurement gap, signal the base station that the UE will use an extended measurement gap of length L at an indicated system frame number (SFN) and subframe number (SN). ### Claim 16 (depends on 13) The apparatus of claim 13, wherein the memory further comprises instructions executable by the at least one processor to cause the apparatus to: after the extended measurement gap, signal the base station that the UE used an extended measurement gap of length L at an indicated system frame number (SFN) and subframe number (SN). ### Claim 17 (depends on 12) The apparatus of claim 12, wherein the adjusting the measurement gap further comprises extending the measurement gap, wherein the extending the measurement gap comprises scheduling a measurement gap of length L based at least in part on a metric. ### Claim 18 (depends on 17) The apparatus of claim 17, wherein L comprises the length of time for the scheduled measurement gap or a number of subframes for the scheduled measurement gap. ### Claim 19 (depends on 17) The apparatus of claim 17, wherein the metric comprises serving cell carrier-to-interference-and-noise-ratio (CINR) or signal-to-interference-and-noise-ratio (SINR). ### Claim 20 (depends on 17) The apparatus of claim 17, wherein the memory further comprises instructions executable by the at least one processor to cause the apparatus to: measure neighbor cell signal strength during the extended measurement gap;
