Problems solved by technology

[0003] Since the terminal equipment frequently sends HARQ feedback information, it may cause interference between the HARQ feedback information sent by different terminal equipment, so that the network equipment cannot correctly receive the HARQ feedback information
[0004] The network device may misinterpret NACK as ACK, and then the network device will no longer retransmit the failed transport block (TB, Transport block), resulting in a decrease in the transmission efficiency of the system and deteriorating the indicators of the communication system
[0005] Network devices may also misinterpret ACK as NACK, and then resend TBs that do not need to be retransmitted, resulting in the retransmission of TBs occupying additional system resources, blocking the transmission of other data, and reducing the data transmission efficiency of the system

Abstract

The invention provides an information transmission method and device. The method comprises the steps that terminal equipment receives downlink data from network equipment; the terminal equipment determines a first sequence when receiving the downlink data successfully, or the terminal equipment determines a second sequence when not receiving the downlink data successfully, and the amplitude of thefirst sequence is different from that of the second sequence; and the terminal equipment sends the first sequence or the second sequence to the network equipment. The invention provides the information transmission method and device, which are favorable for improving the transmission efficiency of a system.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and device for transmitting information. Background technique [0002] In an existing communication system, a terminal device receives downlink data and generates hybrid automatic repeat request (HARQ) feedback information, wherein the HARQ feedback information includes a positive acknowledgment message (positive acknowledgment, ACK) and a negative acknowledgment message (negative acknowledgment). acknowledgment, NACK). The positive response message indicates that the terminal device has successfully received (correctly received) the downlink data; the negative response message indicates that the terminal device has not successfully received (incorrectly received) the downlink data. [0003] Since the terminal equipment frequently sends HARQ feedback information, it may cause interference between the HARQ feedback information sent by different terminal e...
