Problems solved by technology

But in the lower frequency band, only very limited frequency resources can be used for wireless communication, so the system bandwidth that can be realized is small (such as less than 20MHz)

Embodiment Construction

[0037] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] figure 1Represents a system for HWC in discontinuous frequency bands according to a preferred embodiment of the present invention. This system consists of a BMC subsystem and a BHA subsystem. The BMC subsystem covers areas 11 other than hotspots and high-speed high-speed in the hotspot area. Mobile users, BHA subsystem coverage area 13 is a hotspot area except for high-speed mobile users. The BMC subsystem is used in the low-frequency spectrum to provide wide-area coverage that supports high mobility, and the BHA subsystem is used in the high-frequency spectrum to provide support for low mobility. The hotspot coverage of the above-mentioned BMC subsystem and the above-mentioned BHA subsystem are coordinated by the method of JS. The BMC subsystem and the BHA subsystem can adopt the same network topology, that is, the base stations 12...

Abstract

The system comprises: a wideband mobile cellular subsystem and a wideband hot-point access subsystem. The wideband mobile cellular subsystem covers the edge area of the cell and the terminal moving in high speed; the wideband hot-point access subsystem covers the center area of the cell and the terminal moving in low speed; using a jointly scheduling approach to accord the wideband mobile cellular subsystem and the wideband hot-point access subsystem.

Description

technical field [0001] The present invention relates to the technical field of wireless communication systems, in particular to a system and method for hybrid wireless communication in discontinuous frequency bands. Background technique [0002] As the wireless communication technology develops in the direction of larger bandwidth, it is more and more difficult to find ultra-large bandwidths that can be used for wireless communication systems. At present, the bandwidth of a wireless communication system has reached about 20MHz. If the FDD (Frequency Division Duplex, hereinafter referred to as FDD) mode and the uplink and downlink symmetrical spectrum allocation mode are adopted, a system will occupy a total of 40MHz of spectrum. It is quite difficult to simultaneously allocate such frequency spectrum for multiple operators in the existing frequency bands suitable for mobile communication (eg frequency bands below 3 GHz). But the next generation wireless communication system...
