Problems solved by technology

[0007] Since there are multiple carriers in the LTE-A system, the user terminal also needs to know the system information of each carrier aggregation cell when performing carrier aggregation transmission, but it is currently difficult for the user terminal to know the system information of each cell

Embodiment Construction

[0039]In the embodiment of the present invention, the network side determines from the aggregated transmission information set corresponding to each carrier aggregation cell that the aggregated transmission information in the aggregated transmission information set corresponding to the primary serving cell where the user terminal is located has the same information type and different information content, and sends the aggregated transmission information to the user The terminal sends the determined aggregated transmission information, where the aggregated transmission information set is a set composed of information used in carrier aggregation transmission in the system information corresponding to the carrier aggregation cell. In the LTE-A system, the network side can send system information to the user terminal, so that the user terminal can know the system information of each carrier aggregation cell, so that carrier aggregation transmission and multi-carrier switching can be...

Abstract

A method, system and device for transmitting system information are used for informing user terminal of the system information to realize carrier aggregation transmission in Long Term Evolution- Advanced (LTE-A) system, and the method includes: the network side determines the aggregation transmission information which has the same information type and the different information content with the aggregation transmission information set corresponded to the main serving cell in which the user terminal locates, according to the aggregation transmission information set corresponded to each carrier aggregation cell, the aggregation transmission information set is a set of information which is used in carrier aggregation transmission in the system information corresponded to the carrier aggregation cell (501); the network side sends the determined aggregation transmission information to the user terminal (502). The present invention enables user terminal to know the system information of each carrier aggregation cell, can reduce signaling overhead, and can save the consumption and electric quantity of the user terminal.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and equipment for sending system information. Background technique [0002] In the current LTE (Long Term Evolution, long-term evolution) system, there can only be one carrier in a cell, and the maximum bandwidth is 20Mhz, such as Figure 1A shown. [0003] For the LTE-A (LTE-Advanced, Enhanced Long Term Evolution) system, the peak rate of the LTE-A system has been greatly improved compared with the LTE system. The LTE-A system requires a downlink of 1Gbps and an uplink of 500Mbps. Obviously, the bandwidth of 20Mhz can no longer meet this demand. In order to make the LTE-A system meet the requirements, CA (Carrier Aggregation, Carrier Aggregation) technology is introduced, that is, under the same eNB (base station), multiple continuous or discontinuous carriers are gathered together to serve terminals at the same time when needed. To provide the requ...
