Problems solved by technology

[0003] However, since both the WiMAX network and the LTE-TDD network use the TDD time division duplex system, when the WiMAX network and the LTE-MAX network are deployed in the same area, the coexistence performance between the two networks must be considered, especially when two When the network uses the same TDD frequency, if there is no good synchronization, there will be mutual interference between the networks, resulting in deterioration of network performance

Abstract

The embodiment of the invention discloses a method, base station and system for synchronization of an LTE-TDD (Long Term Evolution-Time Division Duplex) network and a WiMAX (Worldwide Interoperability for Microwave Access) network, which are used for realizing synchronization between the LTE-TDD network and the WiMAX network. The method disclosed by the embodiment of the invention comprises the following steps of: synchronizing the LTE-TDD network and the WiMAX network with a same clock source; determining a frame structure of the WiMAX network; and determining a half-frame structure of the LTE-TDD network according to the frame structure of the WiMAX network, and determining a delay time of a frame header of the half-frame structure of the LTE-TDD network relative to a frame header of the frame structure of the WiMAX network, so as to enable the LTE-TDD network and the WiMAX network to reach synchronization.

Description

technical field [0001] The invention relates to a wireless communication system, in particular to a method, a base station and a system for synchronizing an LTE-TDD network and a WiMAX network. Background technique [0002] With the development of communication technology, Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for Microwave Access), as a mobile TDD bandwidth technology, has been widely deployed and applied around the world. At the same time, Long Term Evolution (LTE, Long Term Evolution ) system supports Time Division Duplexing (TDD, Time Division Duplexing) technology. With the maturity of LTE-TDD technology, LTE-TDD network will be gradually deployed and applied. [0003] However, since both the WiMAX network and the LTE-TDD network use the TDD time division duplex system, when the WiMAX network and the LTE-MAX network are deployed in the same area, the coexistence performance between the two networks must be considered, especia...
