Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] In the embodiment of the present invention, the measurement restriction in the connected state is notified to the UE through RRC dedicated signaling, but in the idle state, the UE cannot receive the RRC dedicated signaling, so the UE can only be notified through a measurement message. Specifically, the measurement restriction is indicated by a measurement message, and a measurement subframe set is configured, so that the UE can perform restricted measurement on the cell to be measured according to the measurement subframe set. Therefore, in the heterogeneous network configured with the ABS, the UE can also perform restricted measurements in the RRC idle state, thereby improving the reliability of the measurements.

Abstract

Provided is a measurement method in a heterogeneous network. The measurement method includes measurement limit indicates through measurement information, measurement subframe collection is allocated, and user experience (UE) of users executes limit measurement to small cells to be measured according to measurement subframes. Reliability of measurement under an idle state of a regional resource center (RRC) is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a measurement method in a heterogeneous network. Background technique [0002] In the LTE-Advanced network, in order to provide hotspot coverage and expand cell coverage, a heterogeneous network structure is introduced. The heterogeneous network refers to the deployment of low-power nodes within the coverage area of ​​a macro base station (macro eNB), thereby forming a heterogeneous network system including different node types. Low power nodes include pico base stations (pico eNBs), home base stations (Home eNBs) and relay base stations (Relay eNBs). [0003] The introduction of small cells in the heterogeneous network leads to more cell boundary areas, which causes serious interference. In addition, LTE R10 introduces a coverage expansion (Range expansion) technology for a pico cell. Range expansion refers to deliberately expanding the coverage of a m...
