Abstract

The application discloses a feedback information receiving method, sending method, device and system, belonging to the communication field. The method includes: the terminal sends uplink data in a first time unit; when the terminal does not receive feedback information of the uplink data in any time unit of the first time unit set, determining that the uplink data is Received correctly; wherein, the first set of time units includes at least one time unit after the first time unit. The present invention solves the problem that the HARQ feedback mechanism in the current LTE system is not suitable as a feedback mechanism for UL grant free transmission; the access network device does not need to send an acknowledgment response to the terminal, so that the terminal can determine that the uplink data is correctly received by the access network device , which saves the transmission resources consumed by the access network device to still send an acknowledgment response to the terminal when the uplink data is correctly received.

Description

technical field [0001] The present application relates to the communication field, and in particular to a feedback information receiving method, sending method, device and system. Background technique [0002] In the Hybrid Auto Repeat Request (HARQ) mechanism, the feedback information refers to the information that the access network device feeds back to the terminal after receiving the uplink data sent by the terminal. The feedback information is used to indicate whether the access network device has correctly received the uplink data sent by the terminal. The feedback information usually includes an acknowledgment (Acknowledgment, ACK) and a non-acknowledgment (Non-Acknowledgment, NACK). Wherein, ACK is used to indicate that the access network has correctly received the uplink data sent by the terminal, and NACK is used to indicate that the access network equipment has not correctly received the uplink data sent by the terminal. [0003] In the Long Term Evolution (LTE)...
