Abstract

The embodiment of the invention discloses a link self-adaption method and device, equipment and a storage medium. The method comprises the following steps: a source node sends a detection message to a destination node based on channel interception before sending target data; and the source node receives a detection response message fed back by the destination node, and sends target data to the destination node according to the optimal data sending rate and the optimal sending power carried in the detection response message. According to the technical scheme provided by the embodiment of the invention, the source node obtains the current real-time link information by sending the detection information to the destination node.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a link adaptation method, device, device, and storage medium. Background technique [0002] In a wireless communication system, since the link quality is greatly affected by the environment, it is necessary to adjust the service rate and transmission power in real time through a link adaptive mechanism in the wireless communication system to achieve communication optimization. [0003] The existing link self-adaptation mechanism usually adopts the method of periodically collecting link information, and uses the link information in the previous period as a reference for the current communication link. The biggest problem with this link self-adaptive mechanism is that it is affected by the acquisition period and is not real-time, and cannot make timely adjustments to sudden link changes. This mechanism is suitable for systems with relativel...
