Problems solved by technology

However, if each frequency point is independently a cell, there are two problems: 1. There will be multiple cells with the same coverage in the same coverage area, which will give additional wireless quality measurement overhead to the user equipment (UE, UserEquipment); 2. If each frequency point is an independent cell, each frequency point needs to be configured with a broadcast channel and a synchronization channel, resulting in a waste of frequency point resources
Therefore, the current multi-carrier NB-IoT system only allows user unicast data to be sent on the non-anchor carrier, so the current multi-carrier NB-IoT system can only alleviate the service overhead on the anchor carrier, and cannot solve the problem. Capacity constraints caused by transmitting data on non-anchor carriers

Abstract

The embodiment of the present invention discloses a carrier configuration method, device and system; the method is applied to the NB-IoT system of the narrowband Internet of Things, and the method includes: configuring non-anchor carrier information except the anchor carrier; Describe the non-anchor carrier information.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a carrier configuration method, device and system. Background technique [0002] Machine-to-machine (M2M, Machine to Machine) communication is an important subject of current research in the fifth-generation mobile communication technology (5G, 5th-Generation). It includes narrowband Internet of Things (NB-IoT, Narrowband-Internet of Thing) technology. The system bandwidth in NB-IoT technology is 180kHz, which can reuse the spectrum of the Global System of Mobile Communications (GSM, Global System of Mobile communication) and reduce the Capable of mutual interference with adjacent GSM channels. [0003] The transmission bandwidth of the NB-IoT system can be the size of a physical resource block (PRB, Physical Resource Block) in the long-term evolution system (LTE, Long Term Evolution), so it can be transmitted on one PRB of the LTE system bandwidth. The current NB-Io...
