With reference to Fig. 2 C are referred to, it illustrates access network equipment using three kinds of frequency domain resources at different sub-carrier interval Send the schematic diagram of synchronization blocks information.Wherein, the first subcarrier spacing is 15kHz, and the subcarrier spacing is provided for the frequency domain of 15kHz The corresponding carrier center in source be located at system working frequency range a quarter position, access network equipment use the subcarrier spacing for The frequency domain resource of 15kHz is sent in the time quantum of synchronization blocks information, sends a synchronization blocks information；Second subcarrier spacing is 30kHz, the subcarrier spacing is located at 2/4ths of system working frequency range for the corresponding carrier center of frequency domain resource of 30kHz Put, access network equipment is using the subcarrier spacing to be sent in the time quantum of synchronization blocks information for the frequency domain resource of 30kHz, hair Send synchronization blocks information twice；3rd subcarrier spacing is 60kHz, and the subcarrier spacing is the corresponding load of frequency domain resource of 60kHz Ripple is centrally located at 3/4ths positions of system working frequency range, and access network equipment is the frequency of 60kHz the subcarrier spacing is used Domain resource is sent in the time quantum of synchronization blocks information, sends four subsynchronous block messages.In Fig. 2 C, black rectangle square is used to refer to Show the time/frequency source block for sending synchronization blocks information.

It should be noted that the corresponding carrier center of the above-mentioned frequency domain resource for each subcarrier spacings is in system work It is only exemplary and explanatory to make the position in frequency range, in actual applications, can be preset according to actual conditions, only needs to protect In demonstrate,proving the frequency domain resource at this n kinds different sub-carrier interval, the frequency shared by the frequency domain resource at any two kinds of different sub-carriers interval Section non-overlapping copies.

In addition, the frequency domain that any two kinds of different sub-carriers in the frequency domain resource being spaced for n kinds different sub-carrier are spaced Resource, the time of synchronization blocks information is sent and using between another sub-carrier using the frequency domain resource of one of which subcarrier spacing Every frequency domain resource send synchronization blocks information time it is incomplete same.Through the above way, transmission of staggering as much as possible is synchronous The time of block message so that the transmission time relatively uniform distribution of synchronization blocks information, it is ensured that terminal searching obtains synchronization blocks information Efficiency.

Alternatively, sent in the time quantum of synchronization blocks information in the frequency domain resource using each subcarrier spacings, connect Log equipment sends a synchronization blocks information.Through the above way, the running time-frequency resource of system can be saved, diversity can also be provided Gain.

With reference to Fig. 2 D are referred to, it illustrates access network equipment using two kinds of frequency domain resources at different sub-carrier interval Send another schematic diagram of synchronization blocks information.Wherein, the first subcarrier spacing is 15kHz, and access network equipment is using the sub- load Wave spacing is sent in the time quantum of synchronization blocks information for the frequency domain resource of 15kHz, sends a synchronization blocks information；Second son is carried Wave spacing is 30kHz, access network equipment use the subcarrier spacing sent for the frequency domain resource of 30kHz synchronization blocks information when Between in unit, also send a synchronization blocks information.Wherein, black rectangle square is used for the time-frequency money for indicating to send synchronization blocks information Source block.
