A kind of localization method and device

Technical field

The present invention relates to communication technical field, more particularly to a kind of localization method and device.

Background technology

Arrowband Internet of Things (Narrow Band Internet of Things, NB-IoT) working stage (Work Item, WI) (Release 13) stage of 3GPP versions 13 by and start.

The target in arrowband internet WI stages is to honeycomb Internet of Things (Cellular Internet of Things, CIoT) Wireless access carry out technology standardization.Technology is extended based on LTE/LTE-A, the network mainly considered Characteristic/target is：Strengthen in-door covering, support a large amount of low-speed device accesses, low time delay sensitiveness, reduction is set Standby cost, reduces equipment power dissipation, the optimization network architecture etc..

NB-IOT communications some characteristics that may be present being currently recognized that have：

NB-IOT terminals have Hypomobility；

The time that NB-IOT terminals carry out data transmission with network side is controllable；That is NB-IOT terminals can only Accessed within the period that network is specified.

NB-IOT terminals and the data transfer that network side is carried out be not high to the requirement of real-time of data transfer, i.e.,： With time tolerance；

NB-IOT final energies are limited, it is desirable to extremely low power consumption；

The information transfer of small data quantity is only carried out between NB-IOT terminals and network side；

NB-IOT terminals have low implementation complexity；

The NB-IOT terminals of one reality can have above-mentioned one or more characteristics.

Terminal in Internet of Things may be installed in basement or other path losses substantially exceed common LTE equipment Place, in order to allow the terminal can normal being serviced, it is necessary to which network side or terminal pass through to be repeated several times passes Defeated descending DL data or up UL data, such opposite end could decode correct data by merging. Coverage enhancement grade (CE level) residing for terminal is different, and required iterative transfer times are different.CE level Rank is higher, illustrates that the covering that terminal is presently in is weaker, and the required transmission times that repeats is more, so eventually Side or base station could parse correct data by merging decoding.

Currently for different CE level, there is each self-corresponding PRACH (Physical Random Access Channel) to provide Source.Base station can be inferred to the CE level that terminal is presently according to the preamble (foreword) received.
