Embodiment Construction

[0031] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0032] In the embodiment of the present invention, the network side first sends the 802.16e synchronization channel, then sends the 802.16m primary synchronization channel at a time offset of the 802.16e synchronization channel, and finally transmits the 802.16m primary synchronization channel at a time offset Send 802.16m secondary synchronization channel. Among them, the primary synchronization channel of 802.16m has a fixed position in the entire 802.16m network, and is used for user stations to synchronize the 802.16m network. The secondary synchronization channel is specific to the cell, and is used for user stations to synchronize the cell.

[0033] An embodiment of the present invention provides a method for sending a synchronization channel, such as image 3 shown, including the following steps:

[0034] Step s301, t...

Abstract

A transmission method, system and device of synchronous channel. The method comprises that a network side device transmits an auxiliary synchronous channel of 802.16m at the time offset before or after a master synchronous channel of 802.16m; the time offsets between the auxiliary synchronous channel for each cell or carrier and the master synchronous channel of 802.16m are different. When a user station of 802.16m accesses 802.16 network, it directly detects the master synchronous channel of 802.16m so as to complete the super frame syncharonization of the full 802.16m network and does not need to use the synchronous channel of 802.16e to implement the synchronization to 802.16m network.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a transmission method, system and equipment of a synchronous channel. Background technique [0002] The 802.16e standard was completed at the end of 2005. In order to further improve the performance of the 802.16 standard, the IEEE 802.16 working group decided to establish the 802.16m working group, which is dedicated to researching the next generation of mobile WiMAX (Worldwide Interoperability for Microwave Access). generation standard. According to the planning of the IEEE 802.16 working group, this new standard will be completed by the end of 2009. The goal of the newly established working group is to form a competitive and breakthrough broadband wireless access technology that meets the requirements of 4G technology in ITU-R IMT-Advanced, while maintaining interoperability with existing mobile WiMAX standards. The core technologies of 802.16m are OFDMA...
