Description

Carrier configuration method, device and system

Technical Field

The present invention relates to wireless communication technologies, and in particular, to a method, an apparatus, and a system for configuring a carrier.

Background

Machine to Machine (M2M) communication is an important issue of current research in the fifth Generation mobile communication technology (5G, 5 th-Generation). The technology of Narrowband Internet of things (NB-IoT) is included, the System bandwidth in the NB-IoT technology is 180kHz, the frequency spectrum of a Global System for Mobile communication (GSM) can be reused, and the mutual interference with adjacent GSM channels can be reduced.

The NB-IoT system transmission bandwidth may be the size of one Physical Resource Block (PRB) in a Long Term Evolution system (LTE), and thus, may be transmitted on one PRB of the LTE system bandwidth. Current NB-IoT technology may include three modes of operation, a stand-alone (stand-alone) mode, a transmit over guard-band (guard-band) mode, and a transmit over certain PRBs in the system bandwidth of LTE (inband) mode.

For the current NB-IoT technology, it should be noted that, because the capacity of a cell at a single frequency point is very small in the system bandwidth of 180kHz, when a large number of NB-IoT terminals access, the capacity is limited, and thus capacity expansion is required. The simplest and most direct capacity expansion strategy is to use multiple frequency points to cover the same area. However, if each frequency point is independently a cell, there are two problems: 1. a plurality of cells in the same coverage area exist, and redundant radio quality measurement overhead is added to User Equipment (UE); 2. if each frequency point is a cell independently, each frequency point needs to be configured with a broadcast channel and a synchronization channel, which causes waste of frequency point resources.

In order to solve the above problem, a multi-carrier cell policy may be introduced, that is, multiple single frequency points in the same area covered by the same evolved node b (eNB, eNodeB) are aggregated into one multi-carrier NB-IoT system. The specific implementation process may include: multiple single frequency points share the same physical cell identity and share the same anchor carrier. Broadcast channels and synchronization channels are transmitted on an anchor carrier, and traffic channels may be transmitted on a single frequency point within the physical cell. Therefore, the current multi-carrier NB-IoT system only allows users to send unicast data on non-anchor carriers (non-anchor carriers), so the current multi-carrier NB-IoT system can only relieve the traffic overhead on the anchor carriers, and cannot solve the problem of capacity limitation caused by data transmission on the non-anchor carriers.
