In the present embodiment, the secondary synchronization signal and PBCH of synchronizing signal block can indicate the time index of synchronizing signal block Number, therefore, terminal can determine the time of synchronizing signal block according to the secondary synchronization signal and PBCH of synchronizing signal block in radio frames Call number.

Optionally, on the basis of the above embodiments, in a kind of possible realization method of S1021, the network equipment is According to the time index number of the synchronizing signal block, the sequence of secondary synchronization signal is determined；According to the sequence, the synchronization is generated The secondary synchronization signal of block.Correspondingly, in a kind of possible realization method of S1051, terminal is according in the radio frames The sequence and PBCH of the secondary synchronization signal of synchronizing signal block determine the time index number of the synchronizing signal block.The present embodiment can To indicate the different time call number of synchronizing signal block according to the different sequences of secondary synchronization signal, time rope can be saved in this way Quotation marks occupied resource in synchronizing signal block.

Such as：The sequence of the secondary synchronization signal of above-mentioned determination can be one kind in a variety of sequences (such as two kinds), in this way Different sequences can indicate respectively the parity of time index number.Such as：The corresponding time index number of First ray is odd number, The corresponding time index number of second sequence is even number, if the time index number of synchronizing signal block is odd number, the synchronizing signal block Secondary synchronization signal sequence be First ray, if the time index number of synchronizing signal block be even number, the synchronizing signal block The sequence of secondary synchronization signal is the second sequence.

On the basis of the various embodiments described above, illustrated so that the frame number of radio frames is H bits as an example, H is big In 0 integer；Whether 1 bit in H bits is by including that synchronizing signal block indicates in radio frames, i.e., this 1 Binary number can indicate the parity of frame number, such as：If radio frames include synchronizing signal block, which is 1 When, expression frame number is odd number, if not including synchronizing signal block in radio frames, when which is 0, indicates that frame number is Even number.1 bit for example can be minimum 1 in the H bits.Therefore, the present embodiment can save frame Number occupy synchronizing signal block 1 bit resource.In addition, other H-1 bits in the H bits are wireless by this The PBCH instructions of synchronizing signal block in frame.It can be one in four kinds of PBCH scrambling blind examination results that the PBCH, which scrambles blind Detecting result, Kind, such as：First PBCH scrambles blind examination result instruction 00, and the 2nd PBCH scrambles blind examination result instruction 01, and the 3rd PBCH scramblings are blind Result instruction 10 is examined, the 4th PBCH scrambles blind examination result instruction 11.

In this manner, terminal determines that the process of the frame number of radio frames is：Whether terminal includes same according in radio frames Block is walked, determines 1 bit of the H bits；And according to synchronizing signal block in the radio frames PBCH determines other H-1 bits in the H bits.

On the basis of the various embodiments described above, carried out so that the time index number of synchronizing signal block is K bits as an example Illustrate, K is the integer more than 0；1 bit in K bits indicates (example by the secondary synchronization signal of synchronizing signal block The sequence of such as secondary synchronization signal indicates), such as：When the sequence is First ray, indicate that 1 bit is odd number, Such as 1；When the sequence is the second sequence, 1 bit is indicated as even number, such as 0.Therefore, the present embodiment can be with Save the resource that time index number occupies 1 bit of synchronizing signal block.In addition, other positions K-1 two in the K bits into Number processed is indicated by the PBCH of the synchronizing signal block.In this manner, terminal determines the mistake of the time index number of synchronizing signal block Cheng Wei：According to the secondary synchronization signal of synchronizing signal block, 1 bit in K bits is determined；And believed according to synchronous The PBCH of number block, determines other K-1 bits in K bits.

Below for K be different values when be described in detail.

Under the first scene, i.e., above-described embodiment is applied under scene of the frequency more than 6GHz, synchronizing signal battle array Ji Bao 64 synchronizing signal blocks are included, the time index number of this 64 synchronizing signal blocks needs to be distinguished with 6 bits, therefore, K= 6。

In one implementation, in K=6, other 5 bits carry in the PBCH of the synchronizing signal block, Terminal determines that the process of other 5 bits is：According to the PBCH of the synchronizing signal block, other 5 bits are determined.

Such as：Minimum 1 in 6 bits can be indicated by the sequence of secondary synchronization signal, such as indicate 1, and 6 Highest 5 in binary number can be carried directly in PBCH, such as what is carried in PBCH is 00000, then terminal obtains accordingly The time index number obtained is 000001.

In another implementation, in K=6,4 in other 5 bits carry in the synchronizing signal block PBCH in, and other 1 bit by the synchronizing signal block PBCH CRC mask blind examination results indicate, the CRC masks Blind examination result can be one kind in two kinds of Different Results.Terminal determines that the process of other 5 bits is：According to described same The PBCH for walking block, determines 4 bits in other 5 bits, and blind according to the CRC masks of the PBCH Inspection is as a result, determine other 1 bit in other 5 bits.

Both Different Results are for example respectively the first CRC mask blind examination results and the 2nd CRC masks blind examination as a result, first CRC mask blind examination results indicate that 1 system number is 0, and the 2nd CRC mask blind examination results indicate that 1 bit is 1.Such as：6 Minimum 1 in bit can be indicated by the sequence of secondary synchronization signal, such as indicate 1.Such as CRC mask blind examination results Minimum 1 in other 5 bits can be indicated, if the CRC mask blind examination results of the PBCH of synchronizing signal block are second CRC mask blind examination results, it indicates that 1.And other 4 in other 5 bits can directly carry in PBCH, such as What is carried in PBCH is 0000, then the time index number that terminal obtains accordingly is 000011.

In another implementation, in K=6,3 bits in other 5 bits carry same at this In the PBCH for walking block, and other 2 bit is indicated by the CRC mask blind examination results of the PBCH of the synchronizing signal block, The CRC mask blind examinations result can be one kind in four kinds of Different Results.Terminal determines that the process of other 5 bits is： According to the PBCH of the synchronizing signal block, 3 bits in other 5 bits are determined, and according to the PBCH The blind examination of CRC masks as a result, determining other 2 bit in other 5 bits.

These four Different Results are for example respectively the first CRC mask blind examinations result, the 2nd CRC mask blind examinations result, third CRC mask blind examination results and the 4th CRC masks blind examination as a result, the first CRC mask blind examination results instruction 2 system numbers be 00, 2 bits of the 2nd CRC mask blind examination results instruction are 01, and 2 system numbers of the 3rd CRC mask blind examination results instruction are 10,2 bits of the 4th CRC mask blind examination results instruction are 11.Such as：Minimum 1 in 6 bits can be by The sequence of secondary synchronization signal indicates, such as indicates 1.Such as CRC mask blind examination results can indicate in other 5 bits Minimum 2, if the CRC mask blind examination results of the PBCH of synchronizing signal block are the 4th CRC mask blind examination results, it indicates that 11.And Other 3 in other 5 bits can directly carry in PBCH, such as what is carried in PBCH is 000, then terminal evidence This time index number obtained is 000111.

In a second possible scenario, i.e., above-described embodiment is applied under the scene that frequency is 3-6GHz, and synchronizing signal battle array collection can To include 8 synchronizing signal blocks, the time index number of this 8 synchronizing signal blocks needs to be distinguished with 3 bits, therefore, K =3.

In K=3, other 2 bits are indicated by the CRC mask blind examination results of the PBCH of the synchronizing signal block；Institute It is one kind in four kinds of Different Results to state CRC mask blind examination results.Terminal determines that the process of other 2 bits is：Terminal According to the CRC masks blind examination of the PBCH of the synchronizing signal block as a result, determining other 2 bits.
