Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The basic idea of ​​the present invention is to provide a relay system for mobile communication, which uses a digital relay station to implement digital relay between the base station and the user terminal, and the digital relay station uses analog processing for control signals or does not process them, and uses analog processing for data signals. digital processing. In order to ensure that the present invention not only has good relay performance, but also has strong compatibility and low cost for implementing the solution.

[0037] The first embodiment of the relay system of the present ...

Abstract

The invention discloses a relay system for mobile communication, which comprises a plurality of base stations used for directly communicating with a user terminal or communicating with the user terminal through a relay station, a plurality of digital relay stations used for realizing the digital relay between the base stations and the user terminal and applying the analog processing or non-processing to the control signal and applying the digital processing to the data signal. The digital relay station of the invention respectively applies different modes of processing to the control signal and the data signal and only minimum modification of various devices of the present network needs to be carried out for the system, so the relay system not only has good relay performance, but also hasstrong compatibility and delivers low scheme realization cost.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a relay system for mobile communication combining analog and digital. Background technique [0002] The modern mobile communication network adopts the cellular structure, and each wireless node or base station has a complete signal processing function from radio frequency to baseband. ), the repeater is actually a device that only includes radio frequency processing. [0003] The cellular structure can increase the capacity through methods such as cell splitting, but the problem is that the communication relay efficiency and performance decrease. The repeater will reduce the capacity of the uplink, and may become a new source of signal interference, thereby affecting the performance of the entire network. [0004] Based on the above-mentioned situation, digital trunking has received extensive attention, and both IEEE 802.16 and the European R&D program WiNNER have carried ou...
