Abstract

The present invention provides a configuration method and nodes supporting multi-carrier paging. The method comprises: a first node receives, on anchor carriers, information about non-anchor carriers which are broadcast by a second node and can be used for paging; the first node selects one carrier from the anchor carriers and the non-anchor carriers, or selects one carrier from the non-anchor carriers; the first node monitors and receives, on the selected carrier, a paging message issued by a mobility management entity by means of the second node.

Description

Configuration method and node supporting multi-carrier paging Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a configuration method and a node for supporting multi-carrier paging.

Background technique

The rapid development of mobile Internet, Internet of Things, and other business applications has become the main driving force for the development of the fifth generation of mobile communication technology (5G). 5G is urgently required to have the access rate of fiber optics, the connection capacity of 100 billion devices, the perfect real-time experience, and the wireless broadband access capability anytime, anywhere. In addition, important indicators such as energy efficiency, spectrum efficiency and peak rate also need to be considered in the design of 5G systems. In the future mobile network applications, the demand for traffic, the number of terminals and the types of terminals will all show explosive growth. As one of the important scenes and technical means of 5G, Machine Type Communication (MTC) is receiving more and more attention. In the subject of MTC, for the characteristics of low-cost low-throughput type terminals, the research sub-topic of Narrowband-Internet of Things (NB-IoT) is proposed: that is, using the 200kHZ frequency band to provide NB-IoT low-cost terminals. Low throughput wireless communication service.

In the 3GPP R13 phase, the concept of multi-carrier (Multi-Carrier) cell is proposed, that is, a cell consists of multiple frequency points, and each frequency point/carrier occupies a narrow band of 200 khz, but only one frequency band carries narrow-band primary and secondary synchronization. Signals (NB-PSS and NB-SSS, NarrowBand-Primary Synchronization Signal/Secondary Synchronization Signal), Narrow Band-Physical Broadcast Channel (NB-PBCH), and System Information Block (SIB) The frequency point is called Anchor-Carrier or Anchor-Physical Resource Block (Anchor-PRB), which is collectively referred to as Anchor-Carrier in this paper. The other frequency points are called Non-Anchor Carrier (Non Anchor-Carrier) or Non-Anchor-PRB (Non Anchor-Physical Resource Block), which are collectively referred to as Non Anchor-Carrier in these papers. Does not carry NB-PSS/SSS, NB-PBCH and SIB, only carries data traffic phase Off channels, such as Narrowband-Physical Downlink Control Channel (NB-PDCCH, NarrowBand-Physical Downlink Control Channel), Narrowband-Physical Downlink Shared Channel (NB-PDSCH), narrowband physical uplink shared channel (NB-PUSCH) , NarrowBand-Physical Uplink Shared Channel). In this way, the overhead of the common channel is saved, and the number of inter-frequency cells is reduced. In the R13 phase, paging is only carried on the Anchor-Carrier, which will result in limited capacity for Paging.

In the existing LTE system, if the data is to be sent to the user equipment (UE, User Equipment) in the idle state (RRC state is RRC-IDLE), the mobility management entity (MME, Mobility Management Entity) needs to register with the UE. All base station eNodeBs in the tracking area (TA, Tracking Area) send a paging message, and then the eNodeB sends a paging message to notify the UE, as shown in FIG. The UE listens to the paging message at the corresponding location according to the calculation formula of the paging occasion (PO, Paging Occasion). When the UE receives the paging message, it will initiate an RRC connection request to receive the downlink data. After transmitting the paging message, the MME determines whether the current paging is successfully received by the UE according to whether the UE performs the corresponding action next. If the UE is not successfully received, the MME will continue to page in the next paging cycle. The user.

The embodiment of the present invention first proposes a configuration method for multi-carrier for paging. As shown in FIG. 6, in a cell corresponding to a base station eNodeB of an existing LTE system, Non Anchor carries Both the wave and the Anchor carrier exist simultaneously.
