Embodiment 1

[0140] Embodiment 1. The UE's current serving cell (that is, the macro cell) and the small cell (pico cell) that needs to be handed over are cells of the same frequency. For the network architecture, see Figure 5 As shown, the UE moves towards the small cell under the coverage of the macro cell.

[0141] In this embodiment, the process of performing measurement reporting and processing the measurement reporting is as follows:

[0142] First, the base station where the macro cell is located configures the UE to carry its own speed information in the measurement report;

[0143] Specifically, the base station may carry 1-bit indication information in the measurement configuration information configured for the UE to indicate whether the UE needs to carry its own speed information in the measurement report; the base station may also indicate through high-level signaling whether the UE needs Carry its own speed information in the measurement report.

[0144] Then, after receivi...

Embodiment 2

[0148] Embodiment 2. The UE's current serving cell (that is, the macro cell) and the small cell that needs to be handed over are inter-frequency cells, and its network structure is similar to that of Embodiment 1, except that the macro cell and the small cell are inter-frequency cells (such as , the macro cell frequency is f1, the small cell frequency is f2, and f1≠f2). The UE moves towards the small cell under the coverage of the macro cell.

[0149] In this embodiment, the process of performing measurement reporting and processing the measurement reporting is as follows:

[0150] First, the base station where the macro cell is located configures the UE to carry its own speed information in the measurement report;

[0151] Specifically, the base station may carry 1-bit indication information in the measurement configuration information configured for the UE to indicate whether the UE needs to carry its own speed information in the measurement report; the base station may als...

Abstract

The present invention discloses a method of measurement report, and a device of measurement report, used for solving the existing problems that under a heterogeneous network scene, a UE in a high speed moving state may be switched to a small cell, so that the switching failure probability is increased, and the user experience and the overall performance of a system are influenced. The method of the embodiment of the present invention comprises the steps of using the UE to receive the indication information sent by a base station, wherein the indication information is used to indicate that the UE carries the information correlated with the own moving speed at measurement report; using the UE to evaluate the own moving speed; using the UE to report the measurement to the base station when a measurement report condition is satisfied, and carrying the own current speed information in a measurement report message, wherein the speed information is determined by the current evaluation result of the own moving speed. According to the embodiment of the present invention, the UE in the high speed moving state is prevented from being switched to the small cell.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for performing measurement reporting. Background technique [0002] 1. Mobility State Estimation (MSE) of User Equipment (UE) [0003] At present, the mobility state of UE is divided into three types: high speed, medium speed and low speed, that is, high-mobility state (High-mobility state), medium-mobility state (Medium-mobility state) and normal-mobility state (Normal-mobility state). [0004] When the UE is in the idle state (RRC_IDLE state), the judgment of the three mobile states of the UE is based on the number of cell reselections, as follows: [0005] 1) Mobile state detection criteria: [0006] Moderate mobile state: at T CRmax During the time period, the number of cell reselections exceeds N CR_M , but no more than N CR_H ; [0007] Advanced mobility status: at T CRmax During the time period, the number of cell reselections ex...
