Problems solved by technology

[0010] In the TDM interference coordination mode, the non-scheduling period of the LTE system can reach 60~100ms; for the LTE system, the static TDM mode (that is, the length of the scheduling period and the non-scheduling period is fixed) has the following problems: UE detects that the link quality is degraded , when it is necessary to report measurement reports to trigger handover, it may not be able to obtain resources to send measurement reports in time due to non-scheduling cycle restrictions; and due to non-scheduling cycle restrictions, eNB (base station) may not be able to send handover commands to UE in time, resulting in deterioration of LTE link quality , or even handover failure; and due to service changes, the original TDM mode may not be able to meet the delay and rate requirements of the newly established LTE service
[0018] Since the ICO TDM mechanism is an enhanced DRX mechanism, the user equipment cannot distinguish between the configuration of the traditional LTE DRX mechanism and the configuration of the enhanced DRX mechanism for TDM mode through the current RRC signaling

Abstract

The invention discloses a method and device for cooperatively processing interferences coexisting in equipment. The method comprises the steps: a network side informs user equipment of adopting a TDM (Time Division Multiplex) interference cooperating mode of a DRX (Discontinuous Reception) mechanism for cooperating interferences coexisting in the equipment; the user equipment receives information for cooperating interferences coexisting in the equipment by adopting the TDM interference cooperating mode of the DRX mechanism from the network side; and the user equipment cooperatively processes the interferences coexisting in the equipment by adopting the TDM interference cooperating mode of the DRX mechanism. In the embodiment of the invention, the configuration of the TDM mechanism is carried out on the user equipment by the network side, the user equipment can be enabled to recognize the TDM mechanism and the DRX mechanism and differentiate the configuration of the DRX mechanism and the configuration of the DRX mechanism used in the TDM mode.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a processing method and device for in-device coexistence interference coordination. Background technique [0002] (1) Introduction to ICO (In-device Coexistence) [0003] The rapidly growing smart terminal market requires simultaneous support of multiple wireless technologies in one device, for example, LTE (Long Term Evolution, Long Term Evolution) and ISM (Industrial Scientific and Medical), LTE and GPS (Global Positioning System, Global Positioning System) integrated into the same device. Among them, ISM originally meant the frequency band allocated to industry, science and medicine, and the unlicensed frequency band used for scientific research. Here, it refers to the technology using this frequency band, including WLAN (Wireless Local Area Networks, wireless local area network) and Bluetooth (Bluetooth) Typical wireless technologies such as wireless terminal...
