Embodiment 1

[0073] After the first base station receives the cooperation request message sent by the first master base station, it performs the following figure 1 Flow shown:

[0074] S101. The first base station receives the cooperation request message sent by the first master base station, and proceeds to S102;

[0075] S102. The first base station confirms the state of the first base station. If the first base station is currently set as a slave base station, or is not currently set as a master base station or a slave base station, that is, the first base station is currently in a slave base station state or a detection In the listening state, go to S103.

[0076] Further, if the first base station is currently configured as the master base station, that is, in the master base station state, a message that the cooperation request fails is fed back to the first master base station.

[0077] S103: The first base station sets the first base station as a slave base station of the first m...

Embodiment 2

[0089] After the first base station receives the cooperation request message sent by the first master base station, it performs the following figure 2 Flow shown:

[0090] S201. The first base station receives the cooperation request message sent by the first master base station, and proceeds to S202.

[0091]S202. The first base station confirms the state of the first base station. If the first base station is currently set as a slave base station, or is not currently set as a master base station or a slave base station, that is to say, the first base station is currently in the state of a slave base station or a slave base station. In the listening state, go to S203.

[0092] Further, if the first base station is currently set as the master base station, that is, in the state of the master base station, a message that the cooperation request fails is fed back to the first master base station.

[0093] S203, the first base station judges whether the user load ratio of the ...

Embodiment 3

[0108] If the first base station does not receive any cooperation request message within a cooperation period, the following steps may be performed: image 3 The flow shown:

[0109] S301. The first base station confirms its own status. If the first base station is not currently set as a master base station or a slave base station, go to S302.

[0110] Further, if the first base station is currently configured as a master base station or a slave base station, the current state will continue to be maintained.

[0111] S302. The first base station sets itself as the master base station, and proceeds to S303.

[0112] S303. The first base station selects a neighboring cell base station whose RSRP is higher than a third threshold according to the Reference Signal Received Power (RSRP for short) reported by the neighboring cell base stations of the first base station.

[0113] Wherein, the value of the third threshold is related to the level of signal coverage strength of the bas...

Abstract

The invention relates to the technical field of mobile communication, in particular to a base station and a method for mutual cooperation between the base stations, which is used to solve the problem of poor self-adaptive ability in the prior art of planning the network in advance to complete the cooperation set. In the embodiment of the present invention, after the base station receives the cooperation request message sent by the master base station within the cooperation period, if it is confirmed that the base station is not currently set as the master base station, then the base station is set as the slave base station; if the base station is in the cooperation period If no cooperation request message sent by the master base station is received, the base station is set as the master base station when it is confirmed that the base station is not currently set as the master base station or the slave base station. Wherein, the second threshold is equal to or smaller than the first threshold, so that the base station can be flexibly set as the master base station or the slave base station, and can solve the problem of poor adaptability to complete the cooperative set in network planning.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a base station and a method for mutual cooperation between base stations. Background technique [0002] In a mobile communication network with the same frequency network, when two adjacent base stations allocate time-frequency resources to their respective edge users, there may be cases where the same time-frequency resources are allocated to different edge users, resulting in the possibility of conflict between edge users. Serious co-channel interference is generated, which will reduce the signal-to-dry ratio of edge users, thereby deteriorating the performance of edge users. In the Long Term Evolution-Advanced (LTE-A) project, a coordinated multipoint transmission method is proposed. A cooperative relationship is established between two base stations so that edge users can share the same time-frequency resources. In terms of resources, the same data i...
