Abstract

The embodiments of the invention provide a data sending method, terminal equipment and network equipment. The method comprises the following steps that the terminal equipment receives first schedulinginformation, the first scheduling information is used for indicating a first resource, the first resource is used for sending the resource of a first transmission block, and the first scheduling information is also used for indicating a probability value, wherein the probability value is the block error rate of the network equipment which receives a first transmission block on a first resource orthe success probability of the network equipment which receives the first transmission block on the first resource; and the terminal equipment sends the first transmission block on the first resourceaccording to the first scheduling information. In the invention, the terminal device can determine whether to carry out preparation operation for retransmitting all or part of the first transmissionblock according to a probability value, and then the time for retransmitting the part of or all the first transport block can be shortened and retransmission time delay is reduced.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a method for sending data, a terminal device and a network device. Background technique [0002] In an Advanced Long Term Evolution (Long Term Evolution-Advanced, LTE-A) system, the terminal device receives first scheduling information indicating transmission of the first transport block sent by the network device, and transmits the first transport block according to the first scheduling information . If the transmission of the first transmission block sent by the terminal device to the network device fails, the terminal device may retransmit the first transmission block. Specifically, the network device may send second scheduling information indicating retransmission of the first transmission block, the second scheduling information carries indication information instructing the terminal device to retransmit the first transmission block, and the terminal device retr...
