Embodiment 1

[0045] figure 1 It is a flowchart of a link adaptive transmission method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of adaptively adjusting the transmission rate and transmission power in the process of data transmission. This method can be implemented by link adaptive transmission. transmission device, which can be set in terminal equipment or repeaters, such as figure 1 As shown, the method specifically includes the following steps:

[0046] Step 110, receiving the broadcast information sent by the upper node.

[0047] Wherein, the upper node may be a base station or a relay node, and the upper node periodically sends broadcast (beacon) information to the lower node for maintaining the network state. Broadcast information is sent at a fixed rate and transmission power. Each lower node in the network periodically receives the broadcast information sent by the upper node to maintain the network connection with the upper...

Abstract

The embodiment of the invention discloses a link adaptive transmission method and device, equipment and a storage medium. The method includes the steps of receiving broadcast information sent by a superior node; determining a link signal-to-noise ratio, receiving power and first sending power according to the broadcast information; determining link loss according to the link signal-to-noise ratio, the receiving power and the first sending power; determining a sending rate and second sending power according to the link signal-to-noise ratio and the link loss; and sending data to the superior node according to the sending rate and the second sending power. According to the link adaptive transmission method provided by the embodiment of the invention, the transmission rate and the second transmission power are determined according to the link signal-to-noise ratio and the link loss, and the link quality of the transmission link between the two nodes can be adaptively adjusted; therefore, the sending rate and the sending power in the data transmission process are automatically adjusted so as to adapt to a changing network environment, and the optimal transmission is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a link adaptive transmission method, device, device, and storage medium. Background technique [0002] In the relay network, after receiving the data, the relay node usually does not change the original data rate of the data, and uses the original data rate for relay forwarding. However, due to the relay network, the link quality of different links will be different. If the quality of the subsequent link is poor, subsequent reception of the relayed data will fail; if the quality of the subsequent link is good, the original rate will be used for transmission, which will reduce the throughput of the network and further reduce the transmission capacity of the network. Contents of the invention [0003] Embodiments of the present invention provide a link adaptive transmission method, device, device, and storage medium, which can adaptively adjus...
