Problems solved by technology
[0004] However, LTE TDD is a half-duplex mode. The reception and transmission of signals do not occur at the same time. The reference signal and data used to determine the channel quality are sent in different subframes. The channel quality obtained by receiving the reference When data is sent, the channel conditions may have a large difference
At this time, if the data is still sent according to the previously obtained channel quality, it is very likely that the QoS requirements cannot be met.

The embodiment of the present application discloses a method for transmitting data, including: while sending data to a receiver through a channel, at the same time receiving at least one reference signal sent by the receiver through the channel; according to the at least one reference signal to resend the data. This application also discloses other methods and devices for transmitting data. The method and device for transmitting data described in the embodiments of the present application avoids the problem that QoS cannot be guaranteed due to the delay and hysteresis of reference signals in existing data transmission, and can improve the quality of data transmission.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a method and device for transmitting data. Background technique [0002] Future wireless communication services put forward high requirements for end-to-end QoS (Quality of Service). For example, in scenarios such as remote control of surgical equipment or remote control of cars, the end-to-end delay needs to be within 1ms. To avoid lag during operation. To realize extremely high QoS requirements, technically face various challenges. One of them is the need to accurately determine the channel quality, and then determine an appropriate method for data transmission. [0003] In the existing LTE (Long Term Evolution, Long Term Evolution) TDD (Time Division Duplexing, Time Division Duplexing) technology, a special reference signal is designed to facilitate the receiver to determine channel quality. [0004] However, LTE TDD is a half-duplex mode. The reception ...
