Requirements on measurement time to perform measurements that require the User Equipment to tune its receiver to other frequencies are configured in different ways and depending on the length of the OFF time periods and the measurements to be performed, so as to fulfill various requirements on measurement time while allowing autonomous reselection to CSG in CELL FACH. Accordingly, a User Equipment, UE, performs measurements of a plurality of measurement types. The UE performs a measurement of a first measurement type on at least one Closed Subscriber Group, CSG, cell; at least one of a measurement of a second type on at least one carrier frequency of lower or equal priority compared to that of the serving carrier frequency; and a third measurement type on at least one carrier frequency of higher priority compared to that of the serving carrier frequency. In the performed measurements: (a) the at least one of a measurement of the second and the third measurement type is performed during a required time such that first pre-defined requirements for the at least one of a measurement of the second and third measurement type are met, the required time forming part of a time available for measurements, and (b) the measurement of the first measurement type is performed during a remaining time, during which the at least one of a measurement of the second measurement type and a measurementof the third measurement type is not performed wherein the required time and the remaining time form different parts of the time available for measurements (e.g. periods of receiver OFF time of a Discontinuous Reception, DRX, cycle) which are configured by a network node. The application is directed to a User Equipment, a network node and corresponding methods.

The invention discloses a wearable device control method and a wearable device. The method comprises the steps: when the wearable device is in a screen-off state, starting timing; when it is determined that the screen turn-off time of the wearable device exceeds the preset screen turn-off duration, starting an energy-saving mode, and only starting a communication module in the wearable device in the energy-saving mode. When the wearable device is in the screen-off state, the timing is started. When it is determined that the screen turn-off time of the wearable device exceeds the preset screenturn-off duration, an energy-saving mode is started, and only a communication module in the wearable device is started in the energy-saving mode. Therefore, when the screen turn-off time exceeds the preset duration, the electric energy can be saved through the energy-saving mode, and the cruising ability of the wearable device is improved.
