This application claims the benefit of priority to Chinese Patent Application No. 200910077903.9, entitled “METHOD AND APPARATUS FOR DETERMINING THE CONFIGURATION MODE OF SPECIAL SUBFRAME AND THE USAGE MODE OF TIME-DOMIN RESOURCE”, filed on Feb. 3, 2009 with State Intellectual Property Office of PRC, the content of which is incorporated herein by reference in its entirety.
The present invention relates to the field of mobile communication technology, and more particularly to a method and an apparatus for determining configuration of special subframe in a cell, and a method and an apparatus for determining usage of time-domain resource in a cell.
In LTE-TDD system, thanks to Time Division Duplex mechanism, the proportion of uplink-downlink subframes can be configured flexibly.
Technical solutions of the embodiments of the present applicant and/or the prior art will be illustrated more clearly with the following brief description of the drawings. Apparently, the drawings referred in the following description constitute only some embodiments of the invention. Those skilled in the art may obtain some other drawings from these drawings without any inventive labor.
FIG. 1 is a schematic diagram of the frame structure of the LTE-TDD system;
FIG. 2 is a flow chart of a method for determining the configuration of special subframe in a cell provided in an embodiment of the invention;
The embodiments of the present invention disclose a solution for reducing the interference between adjacent cells by adjusting the usage of the time-domain resource or the configuration of special subframe. In the solution, by acquiring the configuration of special subframe in the neighbor cell from notification information which contains an indicator of the configuration of special subframe in the neighbor cell sent from the neighbor cell, the configuration of special subframe which has less interference with the cell itself and to the neighbor cell is selected as the configuration of special subframe in the cell, or usage priorities of respective time slots are set according to the level of interference to the neighbor cell and the level of interference caused by the neighbor cell.
The technical solutions of the embodiments of the present disclosure will be described clearly and completely in conjunction with the drawings. Apparently, the described embodiments are only some rather than all embodiments of the present disclosure. Any other embodiments obtained from the embodiments of the present disclosure by those skilled in the art without any inventive labor fall within the scope of the invention.
Referring to FIG. 2, a flow chart of a method for determining the configuration of special subframe of a cell provided in an embodiment of the invention is shown, which includes the steps of:
