Problems solved by technology

However, due to the mobility of the mobile terminal, it is entirely possible that the mobile terminal is outside the service area and cannot obtain wireless access services. Even if the mobile terminal is within the service area, the transmission of the signal may still be affected by obstacles on the transmission path. shadowing, resulting in a decline in service quality

Embodiment Construction

[0019] In the embodiment of the present invention, in the relay mobile communication system, it is proposed to configure at least two transmission planes on the Un interface protocol stack of RS and eNode B, so that RS and eNode B can pass multiple transmission planes configured on the Un interface protocol stack. There are multiple transmission planes to transmit data, so as to improve the throughput of the Un interface between the RS and the eNode B and reduce the transmission delay of the Un interface.

[0020] The multiple transmission planes configured on the RS and the Un interface protocol stack of the eNode B include a user transmission plane and a control transmission plane, such as figure 2 As shown, it is a schematic structural diagram of the user transmission plane on the Un interface protocol stack of RS and eNode B, where the user transmission plane includes the physical layer (L layer), medium access control MAC layer, radio link control RLC physical layer and p...

Abstract

The invention discloses data transmission method and device based on a relay mobile communication system. The method comprises the steps of allocating at least two transmission planes on a Un interface protocol stack between a relay station RS and a base station eNode B; and transmitting data between the RS and the eNode B through at least two transmission planes allocated on the Un interface protocol stack. The invention can improve the throughput rate of a Un interface between the RS and the eNode B in the relay mobile communication system, and reduce the time relay of the Un interface.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a data transmission method and device based on a relay mobile communication system. Background technique [0002] In the 3rd generation (3G) and beyond 3rd generation (B3G, Beyond 3 Generation) mobile communication systems, cell coverage is an important measure of the wireless access system, in which the wireless access system is generally through the base station or access point to achieve coverage of the wireless service area. However, due to the mobility of the mobile terminal, it is entirely possible that the mobile terminal is outside the service area and cannot obtain wireless access services. Even if the mobile terminal is within the service area, the transmission of the signal may still be affected by obstacles on the transmission path. Shading, resulting in a decline in service quality. Based on these reasons, in order to solve the seamless coverag...
