A measuring method performed by a user equipment (300; 500; 700) for which an analog beamforming scheme is applied, the method comprising: - transmitting, to a serving access node (400; 600; 800), a measurement request for measuring a neighbouring access node which is working at the same frequency as the user equipment (300; 500; 700); - receiving, from the serving access node (400; 600; 800), information related to a series of measurement time gaps; and - after a delay from said receiving step, performing measurement to the neighbouring access node within the series of measurement time gaps, wherein within each of the series of measurement time gaps, the performing step comprises: suspending data communication with the serving access node (400; 600; 800); adjusting a beamforming pattern of the user equipment (300; 500; 700) from a first beamforming pattern to a second beamforming pattern; and detecting and measuring a system signal of the neighbouring access node using the adjusted beamforming pattern; and wherein the information comprises a length of the delay, a period of the series of measurement time gaps, and a length of each measurement time gap; wherein the period of the series of measurement time gaps is a multiple of a period of the system signal of the neighbouring access node, and the length of each measurement time gap is equal to a sum of an offset and a length of a transmitting time gap within which the system signal of the neighbouring access node is transmitted. - transmitting, to a serving access node (400; 600; 800), a measurement request for measuring a neighbouring access node which is working at the same frequency as the user equipment (300; 500; 700); - receiving, from the serving access node (400; 600; 800), information related to a series of measurement time gaps; and - after a delay from said receiving step, performing measurement to the neighbouring access node within the series of measurement time gaps, wherein within each of the series of measurement time gaps, the performing step comprises: suspending data communication with the serving access node (400; 600; 800); adjusting a beamforming pattern of the user equipment (300; 500; 700) from a first beamforming pattern to a second beamforming pattern; and detecting and measuring a system signal of the neighbouring access node using the adjusted beamforming pattern; and wherein the information comprises a length of the delay, a period of the series of measurement time gaps, and a length of each measurement time gap; wherein the period of the series of measurement time gaps is a multiple of a period of the system signal of the neighbouring access node, and the length of each measurement time gap is equal to a sum of an offset and a length of a transmitting time gap within which the system signal of the neighbouring access node is transmitted. suspending data communication with the serving access node (400; 600; 800); adjusting a beamforming pattern of the user equipment (300; 500; 700) from a first beamforming pattern to a second beamforming pattern; and detecting and measuring a system signal of the neighbouring access node using the adjusted beamforming pattern; and wherein the information comprises a length of the delay, a period of the series of measurement time gaps, and a length of each measurement time gap; wherein the period of the series of measurement time gaps is a multiple of a period of the system signal of the neighbouring access node, and the length of each measurement time gap is equal to a sum of an offset and a length of a transmitting time gap within which the system signal of the neighbouring access node is transmitted.
