Problems solved by technology
If the Anchor CC of the LTE-A terminal is not CC_change, it will not be able to know that the system information of the CC has changed, which will cause the system information of the CC_change saved by the terminal to be out of date
When the network needs to activate the data transmission and reception of the terminal on CC_change, the terminal uses the invalid CC configuration information, which will cause data transmission errors

Embodiment Construction
[0098] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0099] In the LTE-A system, usually one base station governs one or more cells (cells), and each cell is composed of one or more component carriers. In the present invention, the cell to which it belongs and other carriers are modified and defined by CC, information or messages on the CC. For example, the cell to which CC_change belongs refers to the cell that includes CC_change as its component carrier. Correspondingly, other carriers refer to the cell that CC_change belongs to. Other carriers in the cell except CC_change; the cell to w...

The invention provides a system information transmitting method, comprising the following steps: a base station judges whether cell carriers (CC) in a cell under the jurisdiction need to update the system information; the base station carries indication information in the system information of CC in the cell under the jurisdiction and indicates whether the cell of CC has CC needing to update the system information, when CC-change needs to update the system information, the base station transmits paging information on other CC in the cell of CC-change and indicates that the system information on the CC is updated; and the base station broadcasts the updated system information on other CC in the cell of CC-change, wherein the updated system information includes the indication information. The invention also provides a system information receiving method and equipment. The technical scheme provided by the invention solves the problem that the terminal in the system can monitor a plurality of CC and timely discover variation of the system information and update the system information.
Description
technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a method and equipment for sending and receiving system information. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) is committed to the evolution of 3G systems. The goal is to develop 3GPP wireless access technology towards high data rate, low delay and optimized packet data Application direction evolution. In the LTE-A (Long Term Evolution-Advanced, Long Term Evolution-Advanced) system, 3GPP requires that the peak rate is greatly improved compared with the LTE (Long Term Evolution, Long Term Evolution) system, and requires downlink 1Gbps and uplink 500Mbps. This requirement can no longer be met on a single carrier, so CA (Carrier Aggregation, Carrier Aggregation) technology is intr...
