Abstract

It is described a method for controlling radio measurements of a user equipment within a cellular network system, wherein the user equipment is served by a cell of a first cell type characteristic, the cell being assigned to a base station, wherein the cellular network system includes the cell and at least one further cell of a second cell type characteristic. The method includes providing, by the base station, a radio measurement configuration to the user equipment, wherein the radio measurement configuration is indicative for parameters to be applied by the user equipment for radio measurements, the radio measurement configuration includes different parameters being assigned to different cell type characteristics, and controlling the radio measurements of the user equipment based on the provided radio measurement configuration.

Claims (33)

1. A method for controlling radio measurements of a user equipment within a cellular network system, wherein the user equipment is served by a cell of a first cell type characteristic, the cell being assigned to a base station, wherein the cellular network system comprises the cell and at least one further cell of a second cell type characteristic, the method comprising:

providing, by the base station, a radio measurement configuration to the user equipment, wherein the radio measurement configuration is indicative for sets of parameters to be applied by the user equipment for radio measurements, the radio measurement configuration comprising at least two different sets of parameters being assigned to different cell type characteristics for a same frequency, and

controlling the radio measurements of the user equipment based on the provided radio measurement configuration at least by configuring the user equipment to apply one of the at least two sets of different parameters for the radio measurements,

wherein the radio measurement configuration comprises a list comprising information of the at least one further cell and the associated cell type characteristic, and wherein the list comprises information about a plurality of neighboring cells and the respective associated cell type characteristic, and wherein the cell type characteristics comprise at least one of the group consisting of cell type, cell coverage, cell capacity, cell size, cell weight, and cell priority.

2. The method as set forth in claim 1 , further comprising

receiving, by the base station, radio measurements from the user equipment, wherein the radio measurements are based on the provided radio measurement configuration, and

scheduling a handover operation of the user equipment from the cell to the further cell based on the transmitted radio measurements.

3. The method as set forth in claim 1 , wherein the radio measurement configuration comprises a table having the cell type characteristics and the assigned parameters.

4. The method as set forth in claim 1 , wherein the parameters are indicative for the measurement behavior and/or the reporting behavior of the user equipment.

5. The method as set forth in claim 1 , wherein controlling the radio measurements of the user equipment is based on the list and the parameters.

6. The method as set forth in claim 1 , wherein controlling the radio measurements of the user equipment is based on the provided radio measurement configuration and a classification state of the user equipment.

7. The method as set forth in claim 6 , wherein the classification state of the user equipment corresponds to a mobility state and is determined by applying mobility state estimation.

8. The method of claim 1 , wherein controlling the radio measurements comprises configuring the user equipment to apply the parameters for radio measurements based on a respective cell type characteristic.

9. The method of claim 1 , wherein each of the at least two sets of different parameters comprises a different value for a time to trigger parameter.

10. A base station for controlling radio measurements of a user equipment within a cellular network system, wherein the user equipment is served by a cell of a first cell type characteristic, the cell being assigned to the base station, wherein the cellular network system comprises the cell and at least one further cell of a second cell type characteristic, the base station comprising:

at least one processor;

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the base station at least to:

provide a radio measurement configuration to the user equipment, wherein the radio measurement configuration is indicative for sets of parameters to be applied by the user equipment for radio measurements, the radio measurement configuration comprising at least two different sets of parameters being assigned to different cell type characteristics of a same frequency, and

control the radio measurements of the user equipment based on the provided radio measurement configuration,

wherein the radio measurement configuration comprises a list comprising information of the at least one further cell and the associated cell type characteristic and wherein the list comprises information about a plurality of neighboring cells and the respective associated cell type characteristic, and wherein the cell type characteristics comprise at least one of the group consisting of cell type, cell coverage, cell capacity, cell size, cell weight, and cell priority.

11. A user equipment being adapted to communicate with the base station as set forth in claim 10 and being adapted to carry out radio measurements based on the provided radio measurement configuration.

12. A cellular network system, the cellular network system comprising a base station as set forth in claim 10 .

13. The base station for controlling radio measurements as set forth in claim 10 , wherein the at least one memory and the computer program code configured to, with the at least one processor, cause the base station at least to:

receive radio measurements from the user equipment, wherein the radio measurements are based on the provided radio measurement configuration, and schedule a handover operation of the user equipment from the cell to the further cell based on the transmitted radio measurements.

14. The base station for controlling radio measurements as set forth in claim 10 , wherein the radio measurement configuration comprises a table having the cell type characteristics and the assigned parameters.

15. The base station for controlling radio measurements as set forth in claim 10 , wherein the parameters are indicative for the measurement behavior and/or the reporting behavior of the user equipment.

16. The base station for controlling radio measurements as set forth in claim 10 , wherein controlling the radio measurements of the user equipment is based on the list and the parameters.

17. The base station for controlling radio measurements as set forth in claim 10 , wherein controlling the radio measurements comprises configuring the user equipment to apply the parameters for radio measurements based on a respective cell type characteristic.

18. A non-transitory computer readable medium comprising computer readable instructions for controlling radio measurements of a user equipment within a cellular network system, wherein the user equipment is served by a cell of a first cell type characteristic, the cell being assigned to a base station, wherein the cellular network system comprises the cell and at least one further cell of a second cell type characteristic, the program instructions executable by a device to cause the device to:

provide, by the base station, a radio measurement configuration to the user equipment, wherein the radio measurement configuration is indicative for sets of parameters to be applied by the user equipment for radio measurements, the radio measurement configuration comprising at least two different sets of parameters being assigned to different cell type characteristics for a same frequency, and

control the radio measurements of the user equipment based on the provided radio measurement configuration at least by configuring the user equipment to apply one of the at least two sets of different parameters for the radio measurements,

wherein the radio measurement configuration comprises a list comprising information of the at least one further cell and the associated cell type characteristic and wherein the list comprises information about a plurality of neighboring cells and the respective associated cell type characteristic, and wherein the cell type characteristics comprise at least one of the group consisting of cell type, cell coverage, cell capacity, cell size, cell weight, and cell priority.
