Abstract

The invention provides a method and a system for solving time-frequency resource conflicts. The method includes that a master control terminal receives PRB (physical resource block) resource occupation information broadcasted by an adjacent master control terminal and searches unoccupied PRB resources according to the PRB resource occupation information; the master control terminal occupies the searched unoccupied PRB resources, the PRB resource occupation information of the master control terminal is broadcast, and a signal is sent to a slave terminal; the slave terminal judges whether resource conflicts happen or not according to the signal sent from the master control terminal, generates a resource conflict report if yes and sends the resource conflict report to the master control terminal; after the master control terminal receives the resource conflict report, the PRB resources are abandoned, and the unoccupied PRB resources are searched again. By the method and system, the problem about resource conflicts between the adjacent master control terminals in an LTE DMO system can be solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for resolving time-frequency resource conflicts. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is a long-term evolution of a general mobile communication system technical standard formulated by the 3GPP (The 3rd Generation Partnership Project, third generation partnership project). The LTE system introduces key transmission technologies such as orthogonal frequency division multiplexing technology and multi-antenna multiple-input multiple-output technology, which significantly increases spectrum efficiency and data transmission rate, and supports multiple bandwidth allocations. Spectrum allocation is more flexible, system capacity and coverage Significantly improved. [0003] DMO (Direct Mode Operation) of the mobile station in the trunking system refers to direct communication between two or more mobile stations ...
