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

The invention discloses a transmission method of a synchronous channel. The method comprises the following steps: a network-side device transmits an auxiliary synchronous channel (802.16m) in an offset manner before or after transmitting a master synchronous channel (802.16m); and the time offset between the auxiliary synchronous channel and the master synchronous channel (802.16m) in each subzone is different. The invention also discloses a transmission system and device of a synchronous channel. When the subscriber station (802.16m) is accessed to the network (802.16), the transmission method can directly detect the master synchronous channel (802.16m) rather than synchronize the network (802.16m) by utilizing the synchronous channel (802.16e), so as to complete the superframe synchronization of the network (802.16m), thereby accelerating the access of the subscriber station to the network and reducing the treatment of the subscriber station.

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...
