Abstract

Embodiments of the present invention provide a resource allocation method and device for relay-assisted smart factory communication. The method includes: according to the relay location, the base station transmission power, the transmission power of the relay to the device, the coded transmission block length from the base station to the device, and The base station is relayed to the different allocation results of the coded transmission block length of the device to obtain multiple allocation schemes; for each allocation scheme, according to the link signal-to-noise ratio, coded transmission block length and the amount of information sent, respectively determine , the link error rate from the base station to the relay and the link from the relay to the device, and combine the link error rates of the three links to obtain the system error rate of each device; obtain the maximum error rate of all device systems when the error rate is minimized The allocation plan allocates the position of the relay, the transmit power of the base station, the transmit power of the relay to the device, the coded transmission block length from the base station to the device, and the coded transmission block length from the base station to the device through the relay. The resource allocation scheme of the method can ensure the lowest error rate of the system.

Description

technical field [0001] The present invention relates to the field of wireless network resource allocation, in particular to a resource allocation method and device for relay-assisted smart factory communication. Background technique [0002] Factory automation applications such as intelligent control and remote operation are constantly promoting the development of industrial Internet technology. The industrial Internet has also changed from the "wired industrial Internet" assisted by Ethernet technology and a small number of wireless solutions to the "wireless industrial Internet" combined with the fifth generation (5G) wireless communication technology. Compared with the "wired industrial Internet", the "wireless industrial Internet" has flexible connections, low installation and maintenance costs, and convenient debugging and configuration, showing great advantages. But industrial applications, especially those targeting real-time control, pose significant challenges to w...
