Abstract

The embodiments of the invention provide a data transmission method, a terminal device and a network device. The method comprises the steps of enabling the terminal device to receive a first assignment sent by the network device; enabling the terminal device to receive downlink data according to the first assignment and generate feedback information of the downlink data; enabling the terminal device to receive a second assignment sent by the network device, the second assignment being used for indicating a start position of an uplink time unit; enabling the terminal device to determine a resource position for sending the feedback information according to the first assignment and the second assignment; and enabling the terminal device to send the feedback information at the resource position. The resource position of the feedback information can be flexibly determined.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, relate to a method for transmitting data, a terminal device, and a network device. Background technique [0002] In the downlink scheduling of the Long Term Evolution (LTE) system, the terminal device receives a physical downlink control channel (Physical Downlink Control Channel, PDCCH) indication (assignment) sent by the network device, and the assignment directly indicates the transmission resource where the downlink data is located (time-frequency resource), modulation and coding scheme. According to the instruction of the assignment, the terminal device receives downlink data in the current downlink subframe, and tries to decode the downlink data, and generates a feedback result, that is, downlink Hybrid Automatic RepeatreQuest (HARQ) feedback (feedback) , and then send the HARQ feedback through the PUCCH channel after 4 subframes. [0003] Here,...
