Problems solved by technology

[0006] However, the above method of multiple retransmissions ensures the reliability of data transmission to a certain extent, but multiple transmissions inevitably increase the data transmission delay
[0007] Therefore, the current communication method makes it impossible to have both low latency and high reliability of data transmission. How to provide a data transmission method with low latency and high reliability is imperative

Abstract

The invention discloses a communication method and communication equipment. According to the embodiment of the invention, the communication device receives a parallel hybrid automatic repeat request (HARQ) communication instruction, wherein the parallel HARQ communication instruction is used for instructing the communication equipment to send or receive data in a parallel HARQ mode, sending the data by the communication equipment in the parallel HARQ mode means that the communication equipment sends at least one data packet with the same content in the same transmission time interval, receiving the data in the parallel HARQ mode by the communication equipment means that the communication equipment receives at least one data packet with the same content in the same transmission time interval, and merges and decodes the received at least one data packet with the same content; and the communication device sends or receives the data in the parallel HARQ mode according to the parallel HARQcommunication instruction. According to the invention, the time delay of data transmission can be reduced, and the reliability of data transmission is improved.

Description

[0001] This application is a divisional application of a Chinese patent application with an application number of 201580069747.5, an application date of July 30, 2015, and an invention title of "a communication method and communication equipment", the entire content of which is incorporated into this application by reference. Technical field [0002] The present invention relates to the field of communication technology, in particular to a communication method and communication equipment. Background technique [0003] The long-term evolution (Long Term Evolution, LTE) communication system aims to provide low-latency, high-reliability data transmission. [0004] In current communication methods, in order to improve the reliability of data transmission between the sender and the receiver, multiple retransmissions are usually used, for example: [0005] In the case that the receiving end fails to decode a data packet successfully, the receiving end will feedback a negative confirmation t...
