Abstract

Embodiments of the present invention provide a method and device for mobility management. The method comprises: determining a first measurement value based on a first reference signal used by a first cell, and determining a second measurement value based on a second reference signal used by a second cell; and performing cell selection and cell reselection or triggering report of a measurement result according to the first measurement value, the second measurement value, and an offset value, the first reference signal comprising a common reference signal (CRS), and the second reference signal comprising a channel state information-reference signal (CSI-RS); or the first reference signal comprising a CSI-RS, and the second reference signal comprising a CRS; or both the first reference signal and the second reference signal comprising a CSI-RS. In this way, in a cell scenario where a CSI-RS is introduced in mobility management, a UE can select a more suitable cell.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a method and device for mobility management. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, with the introduction of Comp (Coordinated multiple points, coordinated multi-point transmission) technology and new carriers, the CSI-RS (Channel State Information-Reference Signal, channel state information reference signal) signal will Gradually replace the CRS (Common Reference Signal, common reference signal) signal, which is used for channel quality estimation and encoding / decoding of transmission point downlink signals in the Comp scenario, or for the control domain and data domain of downlink signals using new carrier type cells channel estimation and encoding / decoding. The CSI-RS signal is introduced into the mobility management, the cell selection / reselection of the UE (User Equipment, user eq...
