Embodiment Construction

[0167] It should be understood that the term "and / or" used in the embodiments of the present application is only an association relationship describing associated objects, which means that there may be three kinds of relationships, for example, A and / or B may mean: A exists alone, and at the same time There are three cases of A and B, and B alone. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0168] It should be understood that although the terms first, second, third, fourth, etc. may be used to describe CBGs in the embodiments of the present invention, these CBGs should not be limited to these terms. These terms are only used to distinguish CBGs from one another. For example, without departing from the scope of the embodiments of the present application, the first CBG may also be called the second CBG, and similarly, the second CBG may also be called the first CBG.

Abstract

The embodiment of the present application provides a data transmission method, user equipment, and a network device. The method includes that the first user equipment receives a transmission block sent by the network device to the second user equipment, wherein the transmission block includes at least one CBG; the first user equipment receives the first control information sent by the second userequipment, wherein the first control information is used to instruct the first user equipment to send at least one second CBG to the second user equipment, and the second CBG is the first CBG unsuccessfully received by the second user equipment from the network device; and the first user equipment sends at least one third CBG to the second user equipment, wherein the third CBG is the first CBG correctly received by the first user equipment from the network device, and the first CBG unsuccessfully received by the second user equipment from the network device. The data transmission method, the user equipment, and the network device provided by the embodiment of the present application can improve the efficiency of retransmitting the CBG between the first user equipment and the second user equipment.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular, to a data transmission method, user equipment, and network equipment. Background technique [0002] The user equipment cooperation mechanism is introduced in the future 5G communication system. When the user equipment cooperation mechanism is adopted, one or more user equipment located in the central area of ​​network coverage or in a better network environment can assist network equipment and users with poor network service quality in the cell through end-to-end communication technology devices to communicate. In this way, the throughput rate of the user equipment with poor network service quality can be improved, and thus the throughput rate of the entire communication system can be improved. Wherein, the user equipment assisting the user equipment with poor network service quality in the above-mentioned cell may be called cooperation user equipment ...
