Since this mechanism is similar to the HO measurement mechanism, but the event threshold is lower than the HO threshold, this causes the UE to frequently report the ICIC measurement report

Embodiment Construction

[0051] The embodiment of the present invention provides a method for transmitting measurement events of inter-cell interference coordination. By adding a condition for reporting the measurement report of inter-cell interference coordination, the measurement report of inter-cell interference coordination is reported to the base station only when the condition is met. , reducing the frequency of frequently reporting measurement reports for inter-cell interference coordination, and saving system network resources.

[0052] Such as Figure 7 As shown, Embodiment 1 of the present invention provides a method for transmitting inter-cell interference coordination measurement events, including the following steps:

[0053] 101. When the RRC layer of the user equipment (UE) finds that an ICIC measurement report is triggered, that is, when the user equipment detects that the value of the received adjacent cell measurement quantity satisfies a set threshold value or offset value, it consi...

Abstract

The embodiment of the invention discloses methods for transmitting an inter-cell interference coordination measurement event and user equipment. One method comprises the following steps that: when detecting that received neighbor-cell measurement meets inter-cell interference coordination measurement report criteria, the user equipment judges whether an attached event triggering criterion is met; and if the attached event triggering criterion is met, the user equipment triggers the attached event by a media access control layer or wireless resource control layer and transmits an inter-cell interference coordination measurement report as well as uplink and downlink data or directly transmits the measurement report to a base station. The method can reduce the times of the reporting of the inter-cell interference coordination measurement report. The other method reduces the times of the reporting of the inter-cell interference coordination measurement report and allows the base station to know the position of the user equipment in time by setting a threshold for the reporting of the inter-cell interference coordination measurement event, thereby adopting an edge user equipment scheduling policy and interference coordination for users on the edges of cells.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for transmitting inter-cell interference coordination measurement events and user equipment. Background technique [0002] Existing cellular mobile communication systems, such as the 3G system, provide a large difference in the data rate between the center of the cell and the edge of the cell, which not only affects the capacity of the entire system, but also makes the quality of service obtained by users in different locations greatly different. fluctuation. Compared with the current CDMA (Code Division Multiple Access, Code Division Multiple Access) system, the broadband wireless communication system based on OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology, because there is no better randomization between cells in the CDMA system As a result, it will face more serious inter-cell interference pro...
