Embodiment Construction

[0102] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0103] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood that the ...

Abstract

The present disclosure provides a data transmission method and device, wherein the method is used for a primary base station. The method includes: configuring a carrier parameter used by A secondary base station for the secondary base station when the secondary base station is configured for a terminal; configuring an autonomous rejection rule used during intermodulation interference between a carrier used by the secondary base station and a carrier used by the primary base station; sending the carrier parameter and the autonomous rejection rule to the terminal such that the terminal can determine the carrier used by the secondary base station according to the carrier parameter; determining an autonomously rejected carrier according to the autonomous rejection rule when intermodulation interference between the carrier used by the secondary base station and the carrier used by the primary base station occurs, and performing data transmission by using other carriers except the autonomously rejected carrier. Therefore, the present disclosure can ensure the reception of important downlink signaling or the transmission of important uplink signaling of the terminal, and can improve the communication quality.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a data transmission method and device. Background technique [0002] With the continuous development of communication technology, smart terminals have also been widely used. In the new generation communication system, a new application scenario is provided, that is, the EN-DC (EUTRAN NR-Dual Connectivity, LTE network and NR network dual connection) scenario, and the LTE (Long Term Evolution, long-term evolution) network is a 4G network , NR (New Radio, new air interface) network is a 5G network. In this scenario, the terminal needs to maintain two communication links at the same time, one is an LTE communication link and the other is an NR communication link. However, in the related art, if a terminal simultaneously performs uplink transmission on two frequency bands, it may cause serious intermodulation interference to downlink reception of a certain fre...
