Abstract

[Object] To make it possible to perform measurement reporting suitable for an environment in which the on/off state of a cell is switched. [Solution] There is provided a device including: an acquiring unit configured to acquire information indicating that a serving cell is scheduled to be in an off state; and a control unit configured to perform measurement reporting before the serving cell is in the off state.

         4 . The device according to  claim 1 ,
 wherein the control unit performs measurement reporting according to a generation of an event indicating that a serving cell is scheduled to be in the off state.   
     
     
         5 . The device according to  claim 1 ,
 wherein the measurement reporting is measurement reporting of a cell other than the serving cell.   
     
     
         6 . A device comprising:
 a control unit configured to perform measurement reporting according to a generation of a first event regarding a measurement result of a neighbour cell in an on state,   wherein the control unit performs measurement reporting according to a generation of a second event regarding a measurement result of a neighbour cell in an off state, and   the first event and the second event have different offsets or thresholds.   
     
     
         7 . The device according to  claim 6 ,

         8 . The device according to  claim 6 ,
 wherein the neighbour cell in the on state becomes better than a serving cell by a first offset in the measurement result in the first event,   the neighbour cell in the off state becomes better than the serving cell by a second offset in the measurement result in the second event, and   the second offset is greater than the first offset.   
     
     
         9 . The device according to  claim 6 ,

 wherein a serving cell becomes worse than a first threshold and the neighbour cell in the on state becomes better than a second threshold in the measurement result in the first event,   the serving cell becomes worse than a third threshold and the neighbour cell in the off state becomes better than a fourth threshold in the measurement result in the second event, and   the fourth threshold is greater than the second threshold or the third threshold is smaller than the first threshold.   
     
     
         11 . The device according to  claim 8 ,
 wherein the serving cell is a primary cell of carrier aggregation.   
     
     
         12 . The device according to  claim 6 ,
 wherein the neighbour cell in the on state becomes better than a secondary cell by a first offset in the measurement result in the first event,   the neighbour cell in the off state becomes better than the secondary cell by a second offset in the measurement result in the second event, and   the second offset is greater than the first offset.   
     
     
         13 . A device comprising:
 an acquiring unit configured to acquire an offset or a threshold for an event regarding a measurement result of a neighbour cell; and   a control unit configured to notify a terminal device of the offset or the threshold,   wherein the offset or the threshold includes an offset or a threshold for a first event regarding a measurement result of a neighbour cell in an on state and an offset or a threshold for a second event regarding a measurement result of a neighbour cell in an off state, and   the offset or the threshold for the second event is different from the offset or the threshold for the first event.   
     
     
         14 . A device comprising:
 an acquiring unit configured to acquire information about traffic of a terminal device; and   a control unit configured to perform measurement reporting when predetermined conditions of the information are satisfied.   
     
     
         15 . The device according to  claim 14 ,
 wherein the information about the traffic is a traffic load of the terminal device, and   the predetermined conditions include a condition that the traffic load of the terminal device be equal to or greater than a threshold.   
     
     
         16 . The device according to  claim 14 ,
 wherein the information about the traffic is an amount of traffic of the terminal device, and   the predetermined conditions include a condition that the amount of traffic of the terminal device be equal to or greater than a threshold.   
     
     
         17 . The device according to  claim 16 ,
