Method, system and apparatus for system information transmission

Abstract

The embodiment of the present invention discloses a method, system and apparatus for system information transmission, wherein, the method comprises the following steps: the network side configures master system information and wireless resource configuration information of each downlink work carrier in multiple carriers; and to each down-link work carrier in multiple carriers, side network side transmits system information of side down-link work carrier on the down-link work carrier. The system information includes the master system information and wireless resource configuration information of said downlink work carrier, the master system information of other down-link work carrier and / or wireless resource configuration information of at least one of the other downlink work carriers. By using the present invention, the speed and efficiency of the terminal obtaining the system information of other downlink work carrier can be improved in a multi-carrier system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and equipment for sending system information. Background technique [0002] Many new technologies are introduced in LTE-A (LTE-Advanced, subsequent evolution of LTE), and a carrier aggregation (Carrier Aggregation) technology is also introduced as a key technology supporting higher bandwidth transmission. The basic principle of carrier aggregation is to meet higher bandwidth requirements by aggregating two or more basic working carriers together. After the carrier aggregation technology is introduced, the number of working carriers in a cell changes from one to multiple, forming a multi-carrier communication scenario. At present, the system information sending and receiving method of the LTE-A system follows the system information sending and receiving method of the LTE (Long Term Evolution, Long Term Evolution) system. [0003] In the LTE system...

Problems solved by technology

[0029] The transmission and reception of cell system information in the LTE-A multi-carrier scenario is realized through the existing technology. Each downlink carrier in the cell only broadcasts its own system information, and the system information broadcast by each other is relatively independent. When listening to a certain When a terminal of a downlink working carrier wants to obtain the system information of other downlink working carriers in the cell, the terminal needs to re-synchronize, listen and analyze, which reduces the speed and efficiency for the terminal to obtain system information of other downlink working carriers
