Sending method, system and equipment of information in LTE (Long Term Evolution) system

Abstract

The invention discloses a sending method, a system and equipment of information in an LTE system. The method comprises the following steps that: a base station broadcasts system information to a terminal, wherein the system information carries the multi-carrier information of the aggregatable carrier of the LTE system; the base station receives information which is from the terminal and applies for business requiring the support of a carrier aggregation technique; and the base station provides the business requiring the support of the carrier aggregation technique for the terminal according to the applying information. In the invention, through expanding a system information block and carrying the multi-carrier information of the aggregatable carrier in the expanded system information block, an LTE-A (Long Term Evolution-Advanced) terminal acquires whether the base station supports the carrier aggregation technique or not after acquiring the system information; when the base station supports the carrier aggregation technique, the business requiring the support of the carrier aggregation technique is applied to the base station, and thereby, larger used bandwidth and higher peek rate are obtained; and thus, the LTE-A terminal has better use feeling.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, system and equipment for sending information in an LTE 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) are the only standards for the evolution of the LTE wireless network. With a 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 cell capacity and reduce system delay. Among them, the technical characteristics of LTE include high data rate, packet transmission, low delay, wide area coverage and backward comp...

AI Technical Summary

Problems solved by technology

[0011] The content carried in the system information broadcast by the LTE system to the UE cannot fully support the new features of the LTE-A system. For the carrier aggregation feature in the LTE-A system, multiple carriers form a cell of the LTE-A system. The system information cannot indicate which carriers belong to the cells of the same LTE-A system, and the UE cannot know whether the LTE system supports the characteristics of LTE-A, that is, the UE cannot apply for services supported by LTE-A
