Description
Technical field
The present invention relates to communication technical field, the transmission method and a kind of system in particular to a kind of system information
The transmitting device of information.
Background technology
With developing rapidly for mobile service, current wireless communication technology, such as with OFDM (Orthogonal
Frequency Division Multiplexing, OFDM) the forth generation mobile communication technology that is characterized without
Method meets the demand of new scene.In the development all energetically of academia and industrial quarters for the research of the 5th generation communication technology.
However, the research of new generation of wireless communication technology and standardization effort need within long period of time constantly evolution with full
The different scene demand of foot, therefore in standardized initial stage, how to ensure that current standardized technical scheme will not be to rear
It is to need issues that need special attention that the design of the technical scheme being likely to occur during continuous evolution causes obstacle, i.e., current
Emphasis is needed to consider forward compatibility in standardisation process.
5th generation technique needs the message transmission rate for supporting superelevation, the connection number and relatively low data transfer of magnanimity
Time delay is meeting the demand for different scenes.The prevailing scenario of future 5G communication at present includes following three kinds：eMBB(enhanced
Mobile Broadband, enhanced mobile broadband network), mMTC (massive Machine Type Communication,
Large-scale machines class is communicated) and URLLC (Ultra-Reliable and Low Latency Communications, it is highly reliable
Low time delay communicates).And the targeted type of service of these three scenes is different, its demand is also different.Such as eMBB business master

FAXIA, terminal can receive the system information from different districts, and improve System Information reception by merging in receiving side
Reliability.As shown in figure 5,4 cells constitute a collaboration region (i.e. cell cluster), all cells in the region are identical
Time-frequency location on send system information, terminal by what is received is after the system information that these cells send is received
System information is merged, to improve the reliability of System Information reception.
Method 2：Cell in certain area sends system information by way of packet, all little in a packet
Area sends system information on identical running time-frequency resource.The cell of different grouping sends the time-frequency location of system information may phase
Together, it is also possible to different, and the system information that sends of cell of different grouping is probably identical, it is also possible to different.Tool
The packet mode of body can have various, such as can be grouped based on geographical position, it is also possible to based on system information transmissions
Numerology is grouped, or is grouped based on whether identical the information carried in system information is.
Specifically, as shown in fig. 6,4 cells in certain area are grouped two-by-two, each group constitutes a collaboration region
(i.e. cell cluster), all cells in each cell cluster send system information on identical time-frequency location.

It is predefined, and it doesn't matter with carrier frequency point.That is, no matter base station works on which carrier wave, which sends system
What the numerology of system information was just as.
Method 2：The numerology of the different districts Transmission system information in cell cluster is identical, and this numerology is
It is predefined, and this numerology and time domain carrier frequency point are related.In other words, terminal can pre- prophet
The numerology of road system information transmissions and the corresponding relation of base station operation frequency (or frequency range), and then terminal is based in cell
The carrier frequency point information of the base station known in search procedure is determining the numerology of system information transmissions.
Method 3：The set of the numerology of a system information transmissions is defined, each cell can be flexibly at this
Numerology in set selects one of them to carry out Transmission system information.In this case, terminal is needed by various possibility
Numerology carry out reception system information.
Method 4：The numerology of system information transmissions is consistent with the numerology for transmitting cell search signals.
In the case of so, terminal can be determined by the numerology of the cell search signals known in cell search process to be used for
The numerology of reception system information.
