Wireless communication system, base station, mobile station, and wireless communication method

摘要

A wireless communication system controls a transmission timing in each cell so that a control channel of a first cell and a data channel of a second cell temporally overlap each other. The wireless communication system includes a base station of the first cell. The base station of the first cell includes a first control unit and a first communicating unit. The first control unit notifies a base station of the second cell of information used to specify a resource of the control channel of the first cell. The first communicating unit transmits a control signal to a mobile station of the first cell by using a first resource of the control channel of the first cell.

主权项

1. A wireless communication system that controls a transmission timing in each of cells so that a control channel of a first cell and a data channel of a second cell temporally overlap each other, wherein
the wireless communication system comprises a base station of the first cell, a base station of the second cell, and a mobile station of the first cell, and the base station of the first cell includes: a processor configured to execute a first process including:
notifying a base station of the second cell of information used to specify a resource of the control channel of the first cell, the resource corresponding to a predetermined resource unit; andtransmitting a control signal to a mobile station of the first cell by using a first resource of the control channel of the first cell, the first resource corresponding to at least a part of the predetermined resource unit and serving as a decoding object of the mobile station of the first cell, and the base station of the second cell includes: a processor configured to execute a second process including:
transmitting a null symbol by using a second resource of the data channel of the second cell, the second resource corresponding to the predetermined resource unit, and the mobile station of the first cell includes: a processor configured to execute a third process including:
receiving the control signal transmitted by the base station of the first cell via the first resource, wherein the predetermined resource unit is an interference reducing Control Channel Element (CCE) of a picocell.
