A apparatus for use in a user equipment, UE (602, 1200), comprising: radio frequency, RF, circuitry configured to receive an indication of a measurement gap configuration; baseband circuitry coupled with the RF circuitry, the baseband circuitry configured to: identify, based on the indication, a measurement gap repetition period, MGRP; and perform inter-frequency or inter-radio access technology, RAT, measurement based on the measurement gap configuration; determine that a pre-defined measurement condition for requesting a shorter MGRP is met, wherein the shorter MGRP is to reduce a measurement delay, the measurement delay including cell identification delay; and request another measurement gap configuration that includes the shorter MGRP based on whether the determined pre-defined measurement condition is met; wherein the RF circuitry is further configured to: transmit (616, 641) to an evolved Node B, eNB, via radio resource control, RRC, signaling, a request for said other measurement gap configuration that includes the shorter MGRP, when the baseband circuitry requests the other measurement gap configuration; wherein the baseband circuitry is configured to determine that the pre-defined measurement condition for requesting the shorter MGRP is met, if a reference signal receive power, RSRP, or a reference signal received quality, RSRQ, changes between adjacent measurement report periods more than a pre-configured threshold value. radio frequency, RF, circuitry configured to receive an indication of a measurement gap configuration; baseband circuitry coupled with the RF circuitry, the baseband circuitry configured to: identify, based on the indication, a measurement gap repetition period, MGRP; and perform inter-frequency or inter-radio access technology, RAT, measurement based on the measurement gap configuration; identify, based on the indication, a measurement gap repetition period, MGRP; and perform inter-frequency or inter-radio access technology, RAT, measurement based on the measurement gap configuration; determine that a pre-defined measurement condition for requesting a shorter MGRP is met, wherein the shorter MGRP is to reduce a measurement delay, the measurement delay including cell identification delay; and request another measurement gap configuration that includes the shorter MGRP based on whether the determined pre-defined measurement condition is met; wherein the RF circuitry is further configured to: transmit (616, 641) to an evolved Node B, eNB, via radio resource control, RRC, signaling, a request for said other measurement gap configuration that includes the shorter MGRP, when the baseband circuitry requests the other measurement gap configuration; wherein the baseband circuitry is configured to determine that the pre-defined measurement condition for requesting the shorter MGRP is met, if a reference signal receive power, RSRP, or a reference signal received quality, RSRQ, changes between adjacent measurement report periods more than a pre-configured threshold value. transmit (616, 641) to an evolved Node B, eNB, via radio resource control, RRC, signaling, a request for said other measurement gap configuration that includes the shorter MGRP, when the baseband circuitry requests the other measurement gap configuration; wherein the baseband circuitry is configured to determine that the pre-defined measurement condition for requesting the shorter MGRP is met, if a reference signal receive power, RSRP, or a reference signal received quality, RSRQ, changes between adjacent measurement report periods more than a pre-configured threshold value.
