Description

Determine the method and device of the time-domain position of synchronization signal block

Technical field

The present invention relates to the communications fields, method in particular to a kind of time-domain position of determining synchronization signal block and Device.

Background technique

In future wireless system, it will use load more higher than carrier frequency used by forth generation (4G) communication system Wave frequency rate is communicated, such as 28GHz, 45GHz, 70GHz etc., and this high frequency channel has Free propagation loss larger, is held Easily by oxygen absorption, being declined by rain influences the disadvantages of big, has seriously affected the covering performance of high frequency communication system.But due to height Frequency communicates corresponding carrier frequency with shorter wavelength, it is possible to more antenna elements can be accommodated on guarantor unit's area Element, and more antenna elements mean that antenna gain can be improved using the method for wave beam forming, to guarantee that high frequency is logical The covering performance of letter.

After the method for wave beam forming, transmitting terminal can be concentrated emitted energy in one direction, and in other sides Upward energy very little does not have, that is to say, that each wave beam has the directionality of itself, and each wave beam can only cover centainly Terminal on direction, transmitting terminal, that is, base station need the launching beam on tens even a directions up to a hundred that could complete comprehensive cover Lid.In the prior art, the measurement and identification that preliminary beam direction is carried out during terminal initial accesses network, union are inclined to In in a time interval by base station side launching beam poll one time, identify preferred wave beam or port for terminal measurement.Tool Body, there is multiple synchronization signals (Synchronous Signal, referred to as SS)/physics in a synchronization signal sending cycle Broadcast channel block (Physical Broadcast Channel block, referred to as PBCH block), it is later also referred to as same Block is walked, the synchronization signal of carrying particular beam/port (group) in each SS/PBCH block a, synchronization signal is sent Period completes a beam scanning, that is, completes the transmission of all wave beam/ports.Wherein, can also include in SS/PBCH block The corresponding demodulated reference signal of Physical Broadcast Channel PBCH, PBCH, other control channels, other signals such as data channel.

In the prior art, in the time domain a SS/PBCH block by four orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, referred to as OFDM) symbol composition, wherein primary synchronization signal (Primary Synchronous Signal, referred to as PSS) and secondary synchronization signal (Secondary Synchronous Signal, referred to as SSS an OFDM symbol) is occupied respectively, and PBCH occupies 2 OFDM symbols, by 24 continuous resource blocks on frequency domain (Resource Blocks, referred to as RBs) composition, wherein synchronization signal SS is mapped on intermediate 12RBs, and PBCH is mapped to On 24 RBs, one of RB is made of 12 sub- carrier waves.In this way for 6GHz or less carrier frequency, subcarrier spacing 15/ When 30kHz, the bandwidth of SS/PBCH block is respectively as follows: 4.32/8.64MHz.For 6GHz or more carrier frequency, between subcarrier When being divided into 120/240kHz, the bandwidth of SS/PBCH block is respectively as follows: 34.56/69.12MHz.

Under this design method of the relevant technologies, requirement of the different subcarrier spacings to minimum channel bandwidth is different Sample, the minimum channel bandwidth that subcarrier spacing 15/30/120/240kHz is required is respectively 5/10/50/100MHz, in order to make The minimum channel bandwidth of 6GHz or less carrier frequency is no more than 5MHz, and the minimum channel bandwidth of 6GHz or more carrier frequency is no more than 50MHz needs to reduce the bandwidth of PBCH, such as the bandwidth of PBCH is reduced to original half, i.e. PBCH is also mapped to as SS On 12 RBs.In this way, if to keep PBCH Payload constant, and transmission code rate with it is original approximate, then need to increase PBCH The OFDM symbol number of occupancy, therefore the OFDM symbol number that SS/PBCH block is occupied will also accordingly increase, it is therefore desirable to it designs Symbolic number is more than the time-domain position of 4 candidate SS/PBCH block.However scheme in the related art can only design it is small In the time-domain position of 5 candidate SS/PBCH block.

In view of the above problems in the related art, not yet there is effective solution at present.
