Method, apparatus, base station and user equipment for reducing interference in a wireless communication system

摘要

A method, an apparatus, a base station and user equipment for reducing interference in a wireless communication system are provided. The wireless communication system comprises a first cell and a second cell. The method includes mapping a resource grid of at least one of a first type of sub-frame and a second type of sub-frame to reserve at least one resource element in the first type of sub-frame and corresponding to a resource element in the second type of sub-frame and mapped for at least reference signal and a common control channel, and a resource element in the second type of sub-frame and corresponding to a resource element in the first type of sub-frame and mapped for at least one reference signal and a common control channel, for not transmitting information; and transmitting a mapping result of the mapping.

1. A method for reducing interference in a wireless communication system, the wireless communication system comprising a first cell and a second cell, wherein an uplink/downlink sub-frame configuration of the first cell and the second cell is asymmetric and can result in implementing a first type of sub-frame at the first cell while implementing a second type of sub-frame different from the first type of sub-frame at the second cell, thereby producing inter-cell interference, the method comprising:
mapping a resource grid of at least one of the first type of sub-frame and the second type of sub-frame to reserve at least one of a first resource element in the first type of sub-frame and corresponding to a second resource element in the second type of sub-frame and mapped for at least one of a first reference signal and a common control channel, and a third resource element in the second type of sub-frame and corresponding to a fourth resource element in the first type of sub-frame and mapped for at least one of a second reference signal and the common control channel, for not transmitting information; and transmitting a mapping result of the mapping.
