Abstract

The invention provides a wireless communication relay system which comprises relay station, an attribution station and a repeater station. The relay station is connected with the attribution station via the repeater station, and return data to the attribution station via the repeater station. The repeater station comprises a first exchange module, a first terminal module and a second terminal module, the first terminal module and the second terminal module are connected with the first exchange module, the first terminal module is connected to a service cell of the relay station, and configured with a first antenna, and the second terminal module is connected to a service cell of the attribution station, and configured with a second antenna. The relay station uses a first frequency resource, and the attribution station uses a second frequency resource; when the first frequency resource is the same with the second frequency resource, the first antenna and the second antenna are directional antennas; and when the first frequency resource is different from the second frequency resource, the first antenna and the second antenna are directional or omnidirectional antennas. The wireless communication relay system is easy to realize on different occasions.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a wireless communication relay system. Background technique [0002] Relay technology is a flexible and low-cost network deployment technology introduced in Long Term Evolution (LTE for short) Release 10 (Relase 10, R10 for short) to solve signal blind spots and coverage in remote areas. The biggest feature of relay technology is that the backhaul link does not use the wired backhaul link used by traditional base stations, but is connected to a home base station wirelessly, and then connected to the core network, which greatly improves the flexibility of relay station deployment and reduces Operator deployment costs. [0003] The relay system in the prior art includes three links: 1. The backhaul link between the relay station and the home base station uses the Un interface; 2. The access link between the UE served by the relay station and the relay station...
