Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] In the embodiment of the present invention, the macro base station configures the corresponding discovery signal parameters for the micro base stations within its coverage area, and notifies the configured discovery signal parameters to the UEs it serves, so that the served UEs can respond to the corresponding discovery signal parameters based on the corresponding discovery signal parameters. The discovery signal is detected to determine the positional relationship between the UE it serves and each micro cell according to the detection results, so that the inter-frequency measurement can be p...

Abstract

The invention is applicable to the field of mobile communication and provides a different-frequency measuring method and a different-frequency measuring device. The method comprises the steps of transmitting a preset parameter to a micro eNB, wherein the preset parameter is used by the micro eNB for transmitting a finding signal at the working frequency of a macro eNB; transmitting the preset parameter to UE (User Equipment) served by the macro eNB, wherein the preset parameter is used by the UE for detecting the finding signal transmitted by the micro eNB; receiving signal quality information reported by the UE of the detected finding signal; and configuring carrier frequency for executing different-frequency measurement related to the micro eNB for the UE according to the signal quality information. By configuring corresponding finding signal parameters for the micro eNB through the macro eNB and informing the served UE of the configured finding signal parameters to enable the served UE to perform detection on the basis of the corresponding finding signal parameters and then perform different-frequency measurement according to the detection result, the micro cell finding accuracy and efficiency of the UE are improved and the electricity consumed by the UE is effectively saved.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method and device for inter-frequency measurement. Background technique [0002] The existing technology usually uses a heterogeneous network (Heterogeneous Network, HetNet) to increase the network coverage of the mobile communication system, that is, within the coverage of the macro base station (Macro eNB) to access the micro base station (Micro eNB) in a wired or wireless manner, For example, a pico base station (Pico eNB), a home base station (Home eNB), or a relay station (Relay). In order to further improve the system throughput of the above-mentioned HetNet, a plurality of Component Carriers (CC) will be configured on the macro base station and each micro base station to converge into a carrier with a larger transmission bandwidth to support high-speed data rates. [0003] In the above operation scenario, when the user equipment (User Equipment, UE) works...
