Abstract

The embodiment of the invention discloses a cell accessing method for an advanced long-term evolution system, a device and a system thereof. The method comprises the following steps: receiving a synchronous signal transmitted from a single carrier network side and cell broadcast information; acquiring cell identity from the cell broadcast information according to the synchronous signal, wherein the cell identity uniquely corresponds to an advanced long-term evolution system LTE-A cell; acquiring multi-carrier frequency information of the LTE-A cell according to the cell identity; and accessing to the LTE-A cell at arbitrary frequency in the multi-carrier frequency information. According to the embodiment of the invention, the single-carrier terminal ensures that the system can be access to the LTE-A cell at an arbitrary carrier of the LTE-A cell by receiving the multi-carrier frequency information in the cell broadcast information.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a cell access method, device and system of an advanced long-term evolution system. Background technique [0002] In the Long Term Evolution (LTE) system, there can only be one carrier in a cell, and the maximum bandwidth is 20Mhz, you can refer to figure 1 shown. In the Long Term Evolution Advanced (LTE-A) system, the peak rate of the system is greatly improved compared with that of the LTE system. It is required to reach 1Gbps downlink and 500Mbps uplink, which cannot be met on the bandwidth of 20Mhz. Therefore, the LTE-A system introduces carrier aggregation (Carrier Aggregation, CA) technology, that is, in the same cell, multiple continuous or discontinuous carriers are aggregated together to serve the terminal UE at the same time when needed, so as to provide the required rate. In order to ensure that the UE in the LTE system can work under each aggregated carrie...
