Technical field
The present invention relates to the transmission plan in wireless communication system, more particularly to based on Long Term Evolution
The synchronizing sequence of the narrow band communication of (LTE-Long Term Evolution) and broadcast message
Send the method and apparatus for receiving and designing.
Background technology
At 3GPP (3rd Generation Partner Project, third generation cooperative partner program)
In RAN (Radio Access Network, wireless access network) #69 plenary session, NB-IOT
(NarrowBand Internet of Things, arrowband Internet of Things) this problem is set up the project by 3GPP
It is the new Work Item of Release 13, and enters in RAN1#89bis meeting.
The technology will provide improved in-door covering, and the network architecture by optimizing, to realize supporting big
Amount with low traffic low latency sensitivity, ultralow equipment cost, low equipment power dissipation the features such as
UE equipment work.The current technology is divided into three scenes and discusses, respectively：
1. independent operation (Stand-alone operation):For example take current
GERAN (GSM EDGE Radio Access Network, GSM/EDGE wireless communication networks) system
The bandwidth of system carries out narrow band communication, to substitute one or more current GSM (Global System
