Method and device for measurement enhancement in communication system

Abstract

The embodiment of the invention discloses a method and device for enhancing measurement on a small residential area in a closed state. The method performed by a base station side comprises the following steps: sending configuration information to first equipment, wherein the configuration information indicates a special time in a given time interval when one or more residential areas in the closed state are measured; and receiving a measurement report aiming at the residential area from the first equipment, wherein the measurement report is a measurement result of the residential area in the special time based on the first equipment. The embodiment of the invention further provides a corresponding UE method and a corresponding device. According to the method and the device provided in the embodiment of the invention, enhanced measurement on the small residential area can be realized; and thus, resources can be utilized more effectively.

Description

Technical field [0001] The embodiments of the present invention relate to the field of wireless communication technology, and in particular, to a method and device for performing measurement enhancement on a cell in a closed state. Background technique [0002] The small cell, which is a supplement to the macro cellular network, aims to increase network capacity and enhance network coverage. Currently, related research on small cells (small cells or picocells) is being conducted in the Third Generation Partnership Project (3GPP). [0003] A network including macro cells and small cells is also called Heterogeneous Network (HetNet). Although heterogeneous networks have been known to have many advantages such as flexible deployment, significant capacity increase, and easy coverage expansion, the challenges they bring to interference management cannot be ignored. In order to reduce interference and save power, for small cells, the idea of ​​shutting down some small cells has been con...

Problems solved by technology

[0005] However, after introducing the concept of the closed state of the cell, the neighboring cell to be tested by the UE may be a small cell in the closed state, and the user terminal can only obtain the signal of the small cell by measuring the discovery reference signal DRS of the small cell quality

[0006] In the prior art, there is no disclosure of sufficient configuration information required to enable the user terminal to perform effective DRS-based measurements. For example, the user terminal cannot determine whether the duration of the DRS transmission by the small cell in the off state includes MBSFN subframes or uplink subframe

That is, there is currently no effective design scheme for configuration information, so that the UE can effectively measure the small cells in the off state according to the configuration
