Embodiment Construction

[0134] In the present application, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0135] It should be understood that although the terms first and second may be used to describe CQIs in this application, these CQIs should not be limited to these terms. These terms are only used to distinguish CQIs from each other. For example, without departing from the scope of the embodiments of the present invention, the first CQI may also be called the second CQI, and similarly, the second CQI may also be called the first CQI.

[0136]The URLLC service is an important service in the future 5G communication system, which requires very high reliability and very short delay. ...

Abstract

The present application provides a data transmission method, a terminal device, and a network device. The method includes: the terminal device sends first information to the network device; wherein, the first information is used to indicate the first channel quality indicator CQI corresponding to the first block error rate ; The terminal device sends second information to the network device through radio resource control RRC signaling or medium access control MAC signaling; the second information is used to indicate the difference between the first CQI and the second CQI, and the second CQI is the second error The CQI corresponding to the block rate, the first block error rate is greater than the second block error rate. The data transmission method, terminal equipment and network equipment provided by the present application can improve the utilization rate of spectrum resources while ensuring the reliability of URLLC services.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a data transmission method, terminal equipment and network equipment. Background technique [0002] The URLLC service is an important service in the 5G communication system, and requires very high reliability and very short delay during transmission. Therefore, in order to ensure the reliability of the URLLC service, the 5G communication system allows the use of Hybrid Automatic Repeat reQuest (HARQ) technology when transmitting URLLC service data. That is, after sending URLLC service data (including one or more data packets) to the receiver, the sender retransmits the transmission to the receiver according to the negative message fed back by the receiver to indicate that one or more data packets are sent incorrectly. Wrong data packets to reduce the probability of URLLC service data sending errors. [0003] Currently, the terminal device can report a channel quality ...
