Abstract

The invention discloses a method and system for realizing dynamic interference coordination based on RB interference information under LTE, and relates to the field of LTE interference coordination. The method includes the following steps: measuring RB interference information, comprehensively analyzing RB interference information, and calculating the interference result of each RB; according to the RB interference result, using a dynamic adjustment algorithm for judgment processing, and updating the frequency domain resource bitmap; according to the updated The frequency domain resource bitmap is used to allocate and schedule RB resources for different types of users. The present invention enables inter-cell interference information to be transmitted without an X2 interface or other network interfaces, thereby saving network resources.

Description

Technical field [0001] The present invention relates to the field of LTE (Long Term Evolution) interference coordination, and 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 networking have been common. In a complex networking scenario, the interference problem under LTE (Long Term Evolution) limits the planning and distribution of the network to some extent. [0003] In order to solve the interference problem under LTE, the existing specifications give 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 coordination) ). Various equipment suppl...
