Problems solved by technology

[0005] Although the existing technology solves the interference problem between small cells corresponding to different groups, it cannot solve the interference problem between small cells belonging to the same group, so it does not completely solve the interference problem between small cells

Embodiment 1

[0063] The embodiment of the present invention provides a method for managing a small cell network, see figure 1 , the method flow includes:

[0064] 101: Receive a measurement result periodically reported by a user equipment UE, where the measurement result carries a reference signal reception quality of a small cell measured by the UE and an identifier of the small cell;

[0065] 102: Acquire the received quality of reference signals measured by all UEs accessing the small cell according to the identifier of the small cell, and calculate the weight of the small cell according to the received quality of reference signals measured by all UEs accessing the small cell average value;

[0066] 103: Determine whether the small cell needs to adjust the transmission power according to the weighted average value of the small cells, and if necessary, instruct the small cell to adjust its own transmission power.

[0067] This embodiment of the present invention calculates a weighted a...

Embodiment 2

[0069] The embodiment of the present invention provides a method for managing a small cell network, see figure 2 , the method flow includes:

[0070] 201 : Receive a measurement result periodically reported by a user equipment UE, where the measurement result carries a reference signal reception quality of a small cell measured by the UE and an identifier of the small cell.

[0071] After the UE (User Equipment, user equipment) accesses the small cell, it periodically measures the RSRQ (Reference Signal Received Quality, reference signal received quality) of the access small cell. The UE reports the RSRQ to the macro base station after measuring the RSRQ. There are two ways: one way is that the UE directly sends the measurement result to the macro base station for reporting; the other way is that the UE reports the RSRQ to the small cell, and the small cell will collect The RSRQs reported by all the UEs accessing itself are aggregated, and the aggregated RSRQs are sent to th...

Embodiment 3

[0105] The embodiment of the present invention provides a method for managing a small cell network, see image 3 , it should be noted that steps 301 to 302 in this embodiment of the present invention are the same as the processes in the second embodiment, and therefore detailed descriptions are not repeated here.

[0106] The method flow includes:

[0107] 301: Receive a measurement result periodically reported by a user equipment UE, where the measurement result carries a reference signal reception quality of a small cell measured by the UE and an identifier of the small cell.

[0108] Step 301 may be specifically:

[0109] 3011: Receive the measurement result directly reported by the UE periodically; or,

[0110] 3012: Receive a measurement result reported by a UE that accesses the small cell periodically reported by the small cell.

[0111] 302: Acquire the received quality of reference signals measured by all UEs accessing the small cell according to the identifier of the...

Abstract

The invention discloses a method for managing small community networks and a base station and belongs to the field of communication technology. The method for managing small community networks includes receiving measuring results reported on the unified equipment (UE) periodicity of user equipment, obtaining receiving quality of reference signals measured by all UE connected in the small community according to identification of the small community, calculating the weighted average of the small community according to the receiving quality of the reference signals measured by all UE, determining whether transmitting power of the small community needs to be adjusted according to the weighted average of the small community, if the transmitting power of the small community needs to be adjusted, indicating the transmitting power of the small community to conduct adjustment. The weighted average of the reference signal receiving quality of the small community is calculated through the receiving quality of the reference signals measured by all UE, adjust mode of the transmitting power of the small community is determined according to the weighted average, and interfering problems among the small communities of a macro base station are reduced through the adjustment of the transmitting power of the small community. Therefore, the efficiency of solving the problem of interference is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and a base station for managing a small cell network. Background technique [0002] Small cell network SCNs (Small Cell Networks) refers to the deployment of a large number of low-cost, low-power small base stations in the coverage area of ​​macro base stations to form a heterogeneous system of different node types with the same coverage. The same frequency band is reused several times, and the system can Get huge cell splitting gains. In the future, small cells will bear the main traffic volume, while macro base stations will mainly ensure wide coverage, and the number and density of small cells will increase. At this time, the problem of interference between small cells will become more and more serious, so the problem of interference between small cells has become an urgent problem to be solved in SCNs. [0003] In the prior art, small cells ar...
