Description

Multilink transmission system and multilink transmission method Technical Field The present application relates to a multilink transmission system and a multilink transmission method, and more particularly, to a multilink transmission system and a multilink transmission method for adjusting a transmission rate of an information transmission operation by a reinforcement learning device. Background Multi-link operation (MLO) is a wireless communication technology that aims to simultaneously utilize multiple wireless connections to provide higher performance and reliability. Most of the packets are transmitted by the main transmission link, so that the probability of packet transmission by the non-main transmission link is very low, and therefore, a Rate Adaptation (RA) algorithm does not have enough information to adjust the transmission Rate (TX Rate), so that the transmission Rate cannot reflect the state and quality of the current channel, the probability of transmission failure is greatly improved, and the quality of experience (quality of experience, QOE) of a user is reduced. Disclosure of Invention In view of the shortcomings of the prior art, it is an object of the present application to provide, but not limited to, a multi-link transmission system and a multi-link transmission method, which improve the shortcomings of the prior art. In some embodiments, the multilink transmission system includes a transmission information device, a reinforcement learning device, and a feedback device. The transmission information device is used for transmitting a plurality of packets to the receiving end in an initial transmission state through a plurality of channels. The feedback device is used for feeding back the initial transmission state and the transmission result. The reinforcement learning device is used for providing a transmission rate to the transmission information device according to the initial transmission state and the transmission result provided by the feedback device so as to enable the transmission rate of the transmission information device to conform to a plurality of channels. In some embodiments, the multi-link transmission method includes transmitting a plurality of packets to a receiving end in an initial transmission state through a plurality of channels by a transmission information device, feeding back the initial transmission state and a transmission result by a feedback device, and providing a transmission rate to the transmission information device by a reinforcement learning device according to the initial transmission state and the transmission result provided by the feedback device, so that the transmission rate of the transmission information device conforms to the plurality of channels. The technical means embodied by the embodiments of the present application may ameliorate at least one of the disadvantages of the prior art. The multilink transmission system and the multilink transmission method can adaptively adjust the transmission rate of the transmission information device so that the transmission rate of the transmission information device accords with a channel, thereby greatly reducing the probability of transmission failure and improving the quality of experience (quality of experience, QOE) of a user.
