Subcarrier spacing also changed, the subcarrier spacing of long sequence becomes 1.25KHz and 5KHz；The short sequence newly increased
Subcarrier spacing is 15KHz, 30KHz, 60KHz and 120KHz.
In the prior art, according to the usage scenario of long sequence, restriction set can be divided into three kinds of situations, and no limitation is (when long sequence
In use, not needing limitation instruction in low speed scene), restriction set A and restriction set B.The presence of restriction set will affect leading sequence
The length of cyclic shift in column, and then the generation of long sequence is influenced, so needing the limit to long sequence in random access configuration
System collection is indicated.Because there are three kinds of situations for restriction set, 2 bits is needed to be indicated.In four had determined that
In the random access format of the long sequence of kind, format 0 can be used, format 1, format 2, format3 are indicated, wherein before
Subcarrier spacing in three long sequence random access format is 1.25KHz, is divided into 5KHz between 3 sub-carriers of format.
Short sequence is added in 5G it is the performance requirement in order to support new usage scenario with newly propose.Such as carrier frequency is logical
Often in the high-frequency communication of 6GHz or more and the LF communication of a small range.So short sequence has used four subcarrier spacings,
Wherein 15KHz, 30KHz are used in LF communication scene, and 60KHz, 120KHz are used in high-frequency communication scene.In the short sequence having determined
In the random access format of column, be divided into A1, B1, A1/B1, A2, A2/B2, A3, A3/B3, B4, C0, C2 etc., and it is all with
Machine access format can be used in four above-mentioned subcarrier spacings, therefore the leader sequence format of short sequence can not be between sub-carrier
Every being indicated, so needing at least to be indicated with 1 bit.
It is the same with LTE, it is also required to provide the format that corresponding random access uses by random access allocation list in 5G
And the parameters such as time, frequency.According to the agreement agreement reached in standards meetings it is found that 5G random access configures
There are four table meetings, respectively high frequency TDD, low frequency TDD, high frequency FDD, low frequency FDD.Due to long sequence and the respective characteristic of short sequence
Difference is needed according to the random access sequence used in the usage scenario of low frequency to the restriction set of long sequence or short sequence
Subcarrier spacing is indicated.
According to analysis above it is found that indicating respectively the subcarrier of the restriction set and short sequence of long sequence in system message
Interval needs 3 bits in total.However, short sequence does not need restriction set when long sequence needs to indicate restriction set
Instruction；When short sequence needs sub-carrier interval to be indicated, long sequence does not need the instruction of subcarrier spacing.To long sequence
For, the instruction of subcarrier spacing is extra, then the instruction expense of this 1 bit is exactly a kind of waste；Similarly, to short sequence
For, restriction set instruction be also it is extra, the instruction of this 2 bit be also waste.
