Problems solved by technology

As the number of relay nodes increases, several relay nodes will occupy their respective time-frequency resources in the same subframe, and the transmitted binary data will increase, which leads to a serious bottleneck effect
The bottleneck effect refers to the fact that the scarcity of wireless resources cannot meet the needs of the UE, resulting in limited throughput

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] In the downlink of the relay node in the prior art, the data in the subframe of the relay link is sequentially transmitted to the antenna port in a binary sequence, and then sent to the receiving end. The receiving end then performs corresponding processing such as demodulation on the received binary sequence. Since the subframe data that can be allocated to the relay link is limited, each relay node must occupy a certain resource in the subframe to send binary data. The increase of binary data leads to a bottleneck effect in the relay node downlink.

[0040] The invention proposes a communication method for improving system capacity, which is suitable for relay node downlink.

Abstract

The invention relates to a communication method for enhancing system capacity, comprising the following steps of: setting more than one clock rate at a data sending end and a data receiving end; dividing data to be sent into division blocks by the data sending end, transforming the division blocks and obtaining a count value according to the transformed division blocks and the clock rate; respectively setting start bits and stop bits of the transformed division blocks in resource elements sent by the data sending end, wherein the number of the resource elements positioned between the start bits and the stop bits of the transformed division blocks is the count value; starting to count by the data receiving end when receiving the start bits of the transformed division blocks and stopping counting after receiving the stop bits of the transformed division blocks so as to obtain the count value; and obtaining the transformed division blocks by the data receiving end through the count value and the clock rate and then carrying out inverse transformation on the transformed division blocks to obtain the division blocks. The invention also discloses communication system and device for enhancing the system capacity. The embodiment of the invention can be used for reducing the actual transmission quantity, thereby effectively enhancing the capacity of a downlink relay link.

Description

technical field [0001] The present invention relates to the technical field of information transmission in a relay cellular communication system, and more specifically, to a communication method, system and device for improving system capacity. Background technique [0002] Wireless relay technology provides a cost-effective solution. Relay nodes are introduced between base stations and terminals to form a new relay cellular communication system, which can effectively improve network coverage quality, system capacity and resource utilization. . The wireless relay technology is introduced into the Long Term Evolution (LTE) system, and a relay node is introduced between the base station and the terminal of the LTE system to form a Long Term Evolution Advanced (LTE advanced) system. The introduction of relay nodes has a great impact on wireless resource allocation and scheduling. From the perspective of wireless resource allocation, the base station must not only allocate res...
