Abstract

The invention discloses a method for realizing dynamic interference coordination based on RB interference information under LTE and a system thereof and relates to the LTE interference coordination field. The method comprises the following steps of measuring the RB interference information, comprehensively analyzing the RB interference information and calculating an interference result of each RB; according to the interference result of each RB, using a dynamic adjusting algorithm to carry out decision processing and updating a frequency domain resource bitmap; and according to the updated frequency domain resource bitmap, aiming at different types of users, distributing and scheduling RB resources. In the invention, the interference information among cells does not need to be transmitted through an X2 interface or other network interfaces and network resources can be saved.

Description

technical field [0001] The present invention relates to the field of LTE (Long Term Evolution, long-term evolution) interference coordination, in particular to a method and system for realizing dynamic interference coordination based on RB (Resource Block, resource block) interference information under LTE. Background technique [0002] With the development of communication technology, the network structure has become more and more complex, and macro-macro and macro-micro networks have become common. In complex networking scenarios, the interference problem under LTE (Long Term Evolution, Long Term Evolution) restricts network planning and distribution to some extent. [0003] In order to solve the interference problem under LTE, the existing specifications provide a variety of methods, commonly used are ICIC (Inter-cell interference Coordination, inter-cell interference coordination), eICIC (enhanced Inter-cell interference Coordination, enhanced inter-cell interference coo...
