Embodiment Construction

[0105] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0106] As described in the background technology, in view of the defect that the existing technology only has the channel quality assessment method of the LTE system, the embodiment of the present invention provides a channel quality assessment method for the introduction of the carrier aggregation technology in the LTE-A system, by using the carrier The channel quality assessment method in the aggregation technology can provide better service for UE.

[0107] Specifically, after th...

Abstract

The invention discloses a measuring method under carrier aggregation. The measuring method comprises the following steps that: user equipment (UE) receives a message from network side equipment; the UE evaluates channel quality of an aggregable cell according to the message, wherein the aggregable cell is a cell which can be aggregated with the current cell of the UE; and the UE reports a result of the channel quality evaluation to the network side equipment, and the network side equipment performs corresponding processing according to the result of the channel quality evaluation. In the invention, better service can be provided for the UE by evaluating the channel quality of the aggregable cell.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a measurement method, device and system under carrier aggregation. 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 edge users, increase...
