Abstract

The invention provides a method and a device for scheduling empty synchronous subframes, and a base station. The method comprises the following steps: determining a specific time period of each cycle for scheduling synchronous subframes; determining a candidate set of the synchronous subframes in the present cycle according to essential attributes of all subframes in the specific time period; and selecting the synchronous subframes of the present cycle from the candidate set. According to the invention, the empty synchronous time selection problem when no MBSFN subframe configuration exists in a Femto cell can be solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an adaptive synchronization subframe scheduling method and device and a base station when a Femto base station in an LTE system performs air interface synchronization. Background technique [0002] In mobile communication systems, co-channel interference is an important factor restricting system capacity. In particular, the realization of the same-frequency networking technology makes the restriction of the same-frequency interference on the system capacity more prominent. For an LTE (Long Term Evolution, Long Term Evolution) system, not only base stations in adjacent cells will interfere with the current cell, but UEs (user equipment) in adjacent cells will also interfere with the current cell. [0003] The LTE system includes two duplex modes of TDD (Time Division Duplex, time division duplex) and FDD (Frequence Division Duplex, frequency division duplex). In ord...
