Method, system and device for measuring and configuring multi-carrier system

Abstract

The invention discloses a method for measuring and configuring a multi-carrier system, comprising the following steps: acquiring measurement start thresholds of member carriers and / or carrier groups by use equipment (UE); acquiring the signal quality of the member carriers and / or carrier groups; and staring or closing the measurement of the member carriers and / or carrier groups by the UE in accordance with the measurement start thresholds and the signal quality. In the invention, by configuring the measurement start thresholds for the member carriers and / or carrier groups, the UE can start or close the measurement of the member carriers and / or carrier groups in accordance with the measurement start thresholds and the signal quality, thus solving the problem how to start the measurement in multiple working cells by a terminal in accordance with the multi-carrier signal quality, thereby saving electric quantity of the UE and providing greater flexibility for the multi-carrier network management at the same time.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a measurement configuration method, system and equipment for a multi-carrier system. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the evolution of 3G (3rd Generation, third-generation digital communication), LTE improves and enhances 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) ) and MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) as standards for the evolution of the LTE wireless network. Among them, in the LTE system and the previous wireless communication system, there is only one carrier in a cell, such as figure 1 As shown, the maximum bandwidth in the LTE system is 20MHz; and under the spectrum bandwidth of 20MHz, LTE can provide a peak rate of downlink 100Mbit / s and uplink 50Mbit / s, improve the performance of cell ...

AI Technical Summary

Problems solved by technology

[0007] The measurement start thresholds used in the current measurement configuration are all for the UE, that is, each UE has only one measurement start threshold S-measure, so that the measurement start and stop processes can only be performed for the UE

For the LTE-A multi-carrier system, since the UE can aggregate and work on multiple carriers, it is not possible to turn on and off the relevant measurement for multiple carriers of the UE in the prior art
