Embodiment Construction

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0031] (1) Structure example

[0032] figure 1 It is a diagram showing the configuration of a wireless communication system 1 which is an embodiment of the disclosed wireless communication system. The wireless communication system 1 is, for example, a wireless communication system conforming to LTE (Long Term Evolution), and includes a plurality of base stations (hereinafter referred to as eNB (evolvedNodeB)) 10 a , 10 b , and 10 c connected to a mobility management device (MME: Mobility Management Entity) 30 . . The eNBs 10a, 10b, and 10c are connected to the MME 30 through an interface called S1, and the eNBs 10a, 10b, and 10c are connected to each other through an interface called X2, and perform necessary information transmission and reception.

[0033] In the wireless communication system 1 , a mobile terminal (hereinafter referred to as UE (User Equip...

Abstract

A radio communication system (1) includes first and second base stations (10a, 10b) that are capable of communicating with a mobile terminal (20) and are also capable of communicating with each other. The first base station includes a first notification means (13) configured to notify the second base station of first resource information indicating a radio resource which reduces interference from the first base station to communication between the second base station and the mobile terminal. The second base station includes a first allocation means (13) configured to allocate the radio resource indicated by the received first resource information to communication between the second base station and the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of a wireless communication system, a base station and a mobile terminal constituting the system, and a communication control method, and to the technical field of control signal transmission between base stations when a mobile terminal is handed over. Background technique [0002] In a cellular wireless communication system, when a mobile terminal such as a mobile phone moves from a cell of one base station to a cell of another base station, the base station for communication is switched by handover to continue communication. [0003] The communication performance of the cellular system cell as described above is limited by, for example, interference within the cell, interference from other cells (Inter-cell interference), and the like. Therefore, as a frequency repetition method between cells, for example, in LTE (Long Term Evolution) communication technology of 3GPP (Third Generation Partnership P...
