Abstract

The invention provides a method for allocating downlink and uplink proportion used in a wireless communication system, which comprises the following steps: setting a transition area between two adjacent allocation areas with different downlink and uplink proportions and setting layers of the transition area, wherein the layers of the transition area are two times of a difference of downlink or uplink subframes in different downlink and uplink proportions; and according to different downlink and uplink proportions, setting the downlink and uplink proportion of each layer. The method can eliminate the interference caused by different downlink and uplink proportion settings of base stations, thereby ensuring the coexistence of the base stations with different downlink and uplink proportion allocations.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for configuring downlink and uplink ratios in a wireless communication system. Background technique [0002] The mobile WiMAX (Worldwide Interoperability for Microwave Access) system is mainly a mobile communication system based on OFDMA (Orthogonal Frequency Division Multiple Access). Under a given system bandwidth, from the perspective of the frequency domain, different users realize multiple access by occupying a certain number of orthogonal subcarrier resources. In the WiMAX system of TDD (Time Division Duplex) mode, the downlink and uplink are divided by time division, and the corresponding conversion between downlink to uplink and uplink to downlink needs to be set interval. [0003] With the rapid development of communication technology, the mobile WiMAX system based on the IEEE 802.16e air interface standard can no longer meet people's needs for high transmiss...
