Problems solved by technology

[0006] In order to support large-scale networking, the protocol needs to be able to carry out large-scale carrier-level deployment to realize cellular networking. In the IEEE 802.16d Air Interface for Fixed Broadband Wireless Access Systems (Air Interface for FixedBroadband Wireless Access divisionmultiplexing) technology as the physical layer of the system still can not support cellular networking, which limits the further application of this standard technology
[0007] For this problem, in the Chinese patent "Time Sharing Method and Equipment for Frequency Reuse in Cellular Communication System" (application number 96197163.0), a time grouping network method is proposed, and its application in paging system is given However, the technical solution of the invention does not give a specific solution to the current wireless communication application with a large amount of data. In particular, in the case of unbalanced loads between sectors in different directions, the small load sectors in this solution cannot Make full use of bandwidth resources, but the data transmission of overloaded sectors cannot be reliably guaranteed, which will lead to waste of system resources and system congestion

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The use of cellular networking can achieve large-scale coverage, which can provide users with high-quality services and facilitate the operation of large operators. The general networking method uses frequency division (adjacent cells use different frequencies to avoid interference) or code division (different cells use different spreading codes to avoid interference). However, the time-division network has not been well applied. In the case of a packet network, adjacent cells transmit in the same frequency, but differentiate in time, that is, transmit data at different times, thus avoiding interfered.

[0029] For the load balance problem, because the adjustment of the transmission time between adjacent cells in the time-packet network system is relatively simple, it is easier to implement. When there is a problem of sector balance in...

Abstract

A method for balancing load of sector in time division combinational network enables to utilize idle time of sector on small load direction to transmit data of sector on overload direction for releasing data transmission load on overload sector to solve congestion problem of this direction and simultaneously to utilize system bandwidth effectively.

Description

technical field [0001] The present invention relates to the field of wireless communication, specifically, the present invention relates to time grouping network technology. Background technique [0002] Wireless communication is the fastest growing industry in recent years. From GSM (Global System for Mobile Communications) CDMA (Code Division Multiple Access) standard to 3G standard to BWA (Broadband Wireless Access), it fully reflects the huge influence of communication standards With the growing of data services and the gradual emergence of multimedia service requirements, higher requirements are put forward for wireless access technology. The work of making new broadband wireless access technology standards is in full swing. [0003] The IEEE 802.16 series of standards define the wireless MAN (Metropolitan Area Network) air interface specification, which consists of a MAC (Media Access Control) layer and multiple physical layers. This wireless broadband access standard ...
