Problems solved by technology

[0003] Since more than two wireless technologies are simultaneously supported in one device, for example, Long Term Evolution (LTE for short), 5G, Wireless Local Area Networks (WLAN for short), and Bluetooth (Bluetooth, BT for short). ) etc., the transmission operation of one wireless system will cause interference to the reception operation of another wireless system, that is, the IDC interference problem occurs, and in the related art, the NR system does not provide a solution for IDC interference, because for EN- To promote and standardize DC scenarios, it is necessary to propose an interference coordination technical solution for In-Device Coexistence (IDC) interference in EN-DC scenarios

Abstract

The invention discloses an in-device coexistence interference coordination method and device, user equipment and communication equipment. The in-device coexistence interference coordination method includes the steps: receiving an in-device coexistence IDC interference report reported by the user equipment, wherein the IDC interference report carries IDC interference information of the user equipment in an EN-DC scene, and the IDC interference information is used to indicate interference parameters of IDC interference; determining information for IDC interference coordination, based on the IDCinterference report; and sending the information for IDC interference coordination to the user equipment. The technical solution of the in-device coexistence interference coordination method can actively report the IDC interference report when the IDC interference occurs in the EN-DC scene, so as to perform IDC interference coordination, based on the information for the IDC coordinated interference, configured by the base station, thus improving the data transmission performance of the user equipment.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to an in-device coexistence interference coordination method, device, user equipment, and communication equipment. Background technique [0002] In order to commercialize the fifth generation mobile communication technology (5th Generation, referred to as 5G) faster, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) approved the non-standalone (Non-StandAlone, referred to as NSA) Scenario priority standardization, NSA scenario refers to the dual connectivity (EUTRAN-NR DualConnectivity, EN-DC) scenario of the evolved universal radio access network and the next-generation network realized by using the LTE base station as the primary base station and the 5G base station as the secondary base station. -In the DC scenario, the user equipment (User Equipment, referred to as UE) needs to maintain two communication links...
