Information transmission method and device

Abstract

The invention provides an information transmission method and device. The method comprises the steps that a receiving end device receives first information sent by a sending end device in a first target time unit in a subframe a; the receiving end device sends second information corresponding to the first information in a second target time unit in a subframe a + 1, wherein the sub-frame a comprises six first time units, the sub-frame a + 1 comprises two second time units, and the duration of the first time units is different from that of the second time units; if the first target time unit isone of the first three first time units in the six first time units, the second target time unit is the first one of the two second time units; or, if the first target time unit is one of the last three first time units in the six first time units, the second target time unit is the second one of the two second time units.

Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2016 / 070279 with the filing date of January 06, 2016, which entered the Chinese national phase with the Chinese patent application number 201680055312.X, and the title of the invention is "method and device for transmitting information" . technical field [0002] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for transmitting information. Background technique [0003] In future communication technologies, with the continuous expansion of air interface technology and applications, reducing latency will become one of the key performance indicators. For example, the end-to-end delay of Real-time Remote Computing for Mobile Terminals is less than 10ms, the delay requirement of Traffic Efficient and Safety is 5ms, and the existing Long Term Evolution (LTE) , referred to as “LTE” for short), the duration o...

AI Technical Summary

Problems solved by technology

The advantage of short TTI is to shorten the transmission delay, but the corresponding cost is high control signaling overhead and low spectrum efficiency

[0005] Considering that the delay requirements of uplink and downlink services may be different, and the coverage of uplink transmission may be poor, the system may support the use of different TTIs for uplink and downlink, so a method for determining the timing of scheduling and feedback when using different TTIs for uplink and downlink is required method
