Hybrid automatic repeat request indication method and apparatus and storage medium

Abstract

Embodiments of the present application provide a hybrid automatic repeat request indication method and apparatus, and a storage medium. The method comprising the following steps that a network devicesends a radio resource control (RRC) message to a terminal, the RRC message comprising indication information, the indication information being used for indicating that a hybrid automatic repeat request (HARQ) function is enabled or disabled, wherein the indication information is carried by at least one of the following resources: a data channel resource, a broadcast channel resource and a resource block. According to the method disclosed in the invention, the indication information for indicating opening or closing of the HARQ function is carried through the RRC message, so that the method for indicating opening or closing of the HARQ function is realized, the HARQ function in the satellite communication system can be opened or closed according to actual requirements, and the flexibilityof the HARQ function is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a HARQ indication method, device and storage medium. Background technique [0002] In an existing communication system, a hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) is usually used to ensure the reliability of data transmission. For example, the sending end can add some redundant information to the data to be sent, so that the receiving end can correct some errors in the data according to the redundant information when receiving the data, so as to reduce the number of retransmissions. For errors that cannot be corrected by the receiving end, the receiving end needs to request the sending end to resend the data. [0003] With the development of communication technology, satellite communication has become an important part of mobile communication. Satellite communication has the characteristics of long communication distance, large...

Problems solved by technology

[0004] However, the round-trip transmission delay of the signal in the satellite communication system is relatively large, so that the information used by the receiving end to request the sending end to resend the data cannot reach the sending end immediately, and the data resent by the sending end cannot reach the receiving end immediately, making the HARQ function The advantages of HARQ cannot be well reflected in the satellite communication system, therefore, there is an urgent need in the prior art for a method capable of instructing the HARQ function to be turned on or off
