1. A user equipment for cell measurements comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the user equipment at least to perform:
in response to determining that the user equipment is at a cell edge or moving at a high velocity and a signal quality of a serving cell of the user equipment fulfils a certain signal condition that the signal quality meets a first threshold dependent upon at least one of time or location of the user equipment: performing intra-frequency measurements on a serving carrier of the serving cell if one or more one or more neighboring cells on the serving carrier are identified by the user equipment wherein the intra-frequency measurements exclude inter-RAT measurements, otherwise performing at least inter-frequency measurements on a non-serving carrier based upon the signal quality being smaller than a second threshold, the second threshold being smaller than the first threshold, and
applying a carrier specific scaling factor (CSSF) to each of the intra-frequency measurements and the inter-frequency measurements,
wherein the at least one memory and the instructions, when executed by the at least one processor, further cause the user equipment at least to perform: in response to determining that the signal quality of the serving cell fulfils the signal condition and no neighboring cell on the serving carrier is identified by the user equipment: performing intra-frequency measurements on the serving carrier and inter-frequency measurements on the non-serving carrier for a predefined time period, and after the time period has lapsed stopping the intra-frequency measurements and continuing the performing of the inter-frequency measurements on the non-serving carrier, wherein a number of the identified neighboring cells is higher than a predefined minimum number measured over a certain time, wherein each cell of the identified neighboring cells has a signal quality that fulfils a signal quality selection criterion.
