Problems solved by technology

Since the time period of the long TTI is greater than the time period of the above short TTI, according to the transmission characteristics of the long TTI, it is bound to increase the HARQ feedback delay of the short TTI, increase the transmission time of delay-sensitive data, and also cause waste of resources for the long TTI

Abstract

The invention provides a method and a device for acquiring and transmitting HARQ feedback information, wherein the method comprises the steps: short TTI scheduling information is set in first target long TTI according to a business requirement; the short TTI scheduling information is sent to second equipment through the first target long TTI; short TTI is scheduled from second target TTI according to the short TTI scheduling information and is sent to the second equipment; HARQ information of each short TTI which is sent from the second target long TTI in sequence by the second equipment is received. According to the invention, HARQ feedback delay of the short TTI can be effectively reduced, and the flexibility of data transmission can be improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for acquiring and transmitting HARQ feedback information. Background technique [0002] With the development of wireless communication technology, mobile communication networks are gradually evolving to 5G networks. The capabilities of 5G networks in terms of data transmission rate, coverage, delay, and capacity have been greatly improved, and more downlink service types can be configured according to user needs, such as eMBB (enhanced Mobile Broad Band, enhanced mobile broadband), mMTC (massive MachineType Communication, massive machine-type communication), URLLC (Ultra Reliable Low Latency Communication, ultra-reliable low-latency communication), and other types, which are applied to broadband connections, Internet of Things, Internet of Vehicles, and wide-area coverage. [0003] When transmitting non-sensitive service data such as mMT...
