Wireless communication system, mobile station, base station, and wireless communication method for reducing interference of data

摘要

The mobile station receives a wireless signal containing a transmission signal of the macro base station and a transmission signal of the home base station. The mobile station includes a control information receiving unit and a reception processing unit. The control information receiving unit receives first control information used for a process of receiving the transmission signal of the macro base station and second control information used for a process of receiving the transmission signal of the home base station. The reception processing unit demodulates and decodes a signal based on the first control information, where the signal is obtained by reducing a component of the transmission signal of the home base station from the wireless signal by using information obtained by demodulating and decoding the transmission signal of the home base station based on the second control information.

主权项

1. A wireless communication system comprising:
a macro base station; a home base station; and a mobile station that receives a wireless signal containing a transmission signal of the macro base station and a transmission signal of the home base station, wherein the macro base station includes a processor, wherein the processor executes a process comprising:
notifying the home base station of a timing at which the macro base station transmits data to the mobile station, the home base station includes a processor, wherein the processor executes a process comprising:
transmitting control information to the macro base station at the timing notified, and the mobile station includes a processor, wherein the processor executes a process comprising:
transmitting information to the macro base station, the information indicating that the mobile station enables interference reduction;first receiving first control information used for a process of receiving the transmission signal of the macro base station; andsecond receiving, from the home base station, second control information used for a process of receiving the transmission signal of the home base station, the second control information being transmitted to the mobile station in response to a request sent by the macro base station.
