Abstract

Embodiments of the present invention disclose a method and apparatuses for interference coordination in a wireless communication system. The method comprises: detecting, by an interfering eNB, mismatching between subframe configuration of its downlink transmission and subframe configuration of uplink transmission of an interfered eNB; and informing the interfered eNB of a Relative Narrow-Band Transmit Power RNTP with a flag, wherein the flag indicates the RNTP is used for scheduling resource allocation of uplink transmission by the interfered eNB. According to embodiments of the present invention, by adapting the RNTP in Release 8 / 9, an proactive inter-cell interference coordination (ICIC) for the eNB-to-eNB interference can be implemented. Moreover, the RNTP can be used with a message of the OI-like as previously proposed, so as to achieve a better bi-directional ICIC in the eNB-to-eNB interference case.

Description

technical field [0001] Embodiments of the present invention relate to interference coordination in communication systems, and more particularly to methods and apparatus for interference coordination in wireless communication systems. Background technique [0002] In the LTE Time Division Duplex (TDD) system, uplink transmission and downlink transmission adopt time division multiplexing to share time sub-frame resources in the time domain. That is, some subframes of TDD are configured for uplink transmission, and some subframes are configured for downlink transmission. Obviously, if the same uplink and downlink subframe configuration is used between adjacent cells, as in the FDD system, there will be downlink interference from the base station to users in adjacent cells and uplink interference from users to adjacent cells. interference. If the uplink and downlink subframe configurations are different between neighboring cells, then base-to-base and user-to-user interference...
