The embodiment of the invention provides a kind of indicating means of synchronization signal block time index, are applied to network equipment side, As shown in figure 4, this method specifically includes the following steps:
Step 41: generating multiple DMRS sequences.
Wherein, multiple demodulated reference signal (Demodulation Reference Signal, hereinafter referred to as DMRS) sequence Column are for the Physical Broadcast Channel NR-PBCH that newly eats dishes without rice or wine in demodulation synchronization signal block, that is to say, that the DMRS sequence is NR-PBCH DMRS sequence.
Step 42: sending multiple DMRS sequences to terminal, indicate that NR-PBCH is corresponding same by least one DMRS sequence Walk block time index.
The embodiment of the present invention indicates synchronization signal block time index by DMRS sequence, and it is same to enable the terminal to quick obtaining Block time index is walked, the utilization efficiency of DMRS sequence is improved.
In the present embodiment, DMRS sequence implicitly carries all or part of information of synchronization signal block time index, wherein One DMRS sequence can implicit instruction synchronization signal block time index an at least bit information.Specifically, the SS block time Index, which can be divided into two parts, to be transmitted, wherein 2-3 bit indicates that remaining bit passes through NR- by way of DMRS sequence PBCH payload (payload) is transmitted.The SS block time of 2 or 3 bits is carried by the DMRS sequence of NR-PBCH Index, can make terminal when carrying out adjacent cell measurement, and the detection decoding without carrying out NR-PBCH is obtained with part SS Block time index realizes quick positioning and survey of the terminal to adjacent cell so that terminal quickly knows the synchronization signal of adjacent cell Amount.
Specifically, step 41 specifically includes: the transfer resource of NR-PBCH is divided into N group；Configure N group transfer resource pair The DMRS sequence answered.Wherein, the M-bit information of DMRS sequence implicit instruction synchronization signal block time index, N are whole greater than 1 Number, M are the integer greater than 0.That is, some or all of resource of the DMRS sequence of mapping NR-PBCH is grouped, It particularly may be divided into N group, indicate the M-bit letter of synchronization signal block time index in each grouping by using not homotactic mode Breath, can indicate N × M bit information in this way.For example, the transfer resource for the DMRS sequence for mapping NR-PBCH is divided into N group (N =2 or 3), the DMRS sequence in each transfer resource grouping indicates 1 bit information, then N group transfer resource can transmit SS altogether N-bit information in block time index.
Wherein, the parameter preset of multiple DMRS sequences is different, i.e., different DMRS sequences has different parameter presets, in advance Setting parameter includes: at least one in sequence initialization value, shift value and generator polynomial.Above-mentioned DMRS sequence can be gold Sequence, gold sequence are the exclusive or of 2 m-sequences, and the length of the gold sequence c (n) of output is M, n=0,1 ..., M-1.Wherein, The initialization of gold sequence can be realized in the following manner:
C (n)=(x1(n+Nc)+x2(n+Nc)) mod2 formula one
x1(n+31)=(x1(n+3)+x1(n)) mod2 formula two
x2(n+31)=(x2(n+3)+x2(n+2)+x2(n+1)+x2(n)) mod2 formula three
