Embodiment Construction

[0016] The main realization principles, specific implementation methods and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below with reference to each accompanying drawing.

[0017] Relay mainly includes the following two functions:

[0018] The first function: provide wireless backhaul. In some scenarios where optical fiber cannot reach or wired backhaul construction is difficult (for example: indoor office environment without room division deployment, residential buildings where optical fiber cannot reach the home, urban micro-coverage scenarios without wired backhaul, remote suburbs or rural areas, etc.) , by introducing a relay with wireless backhaul function, the coverage can be effectively expanded, the problem of lack of fiber resources can be solved, and the deployment is flexible and convenient.

[0019] The second function: solve coverage enhancement. In the LTE-A R10 stage, at pr...

Abstract

The invention discloses a relay data processing method and apparatus. The method comprises the following steps: obtaining frequency point configuration information of a base station; for each frequency point in the obtained frequency point configuration information, calculating the isolation of a return link and an access link of a relay in using frequency point configuration; and according to the isolation and a set out-band relay isolation threshold, configuring the relay to be at an out-band work mode or a in-band work mode for data processing. According to the invention, the problem can be well solved that the data processing performance of the relay is quite poor because the relay cannot select the corresponding work mode for the data processing according to specific environments of wireless communication in general conditions.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a relay data processing method and device. Background technique [0002] At present, wireless networks are widely used, and the network propagation environment is complex. There are some areas where optical fibers cannot reach or cannot be used for network wiring, or coverage blind areas caused by tall buildings. In order to solve the problem of coverage enhancement, relay nodes can be introduced into the wireless network. (RN, Relay Node), that is, add an RN between the base station and the user terminal (UE, User Equipment), such as figure 1 As shown, the direct transmission link between the base station and the UE is divided into two sections, the link between the base station and the RN is called the backhaul link, and the link between the RN and the UE is called the access link. The interface between the base station and the RN is called the Un interf...
