Abstract

The invention provides a method for controlling UE to report neighborhood information. The method comprises obtaining the wireless link quality information of multiple UEs in a cell through a base station, dividing the multiple UEs into at least two groups according to the wireless link quality information; for the same event triggering reporting, setting different threshold values for every group of the UEs; transmitting the threshold value of the corresponding group to every UE. According to the method for controlling UE to report the neighborhood information, for the groups with relatively poor wireless link quality, only a small number of UEs need to report the neighborhood information, so that signaling costs can be reduced, and the system performance can be improved. Besides, the invention also provides the base station for controlling the UE to report the neighborhood information.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a device, a base station and a method for controlling user equipment to report neighbor cell information. Background technique [0002] In a long term evolution (LTE) system, in order to obtain neighbor cell information, the base station sends a measurement to a connected user equipment (UE) through radio resource control (RRC) signaling. configuration information. The UE detects the signal state or channel quality of the neighboring cell according to the parameters indicated in the measurement configuration information, such as the measurement object, the reporting configuration, and the measurement identifier. The reporting configuration includes periodic trigger reporting or event trigger reporting. When the reporting configuration is set to event-triggered reporting, the reporting configuration includes parameters such as event type, threshold value, ...
