Length of field；The frequency band length of each frequency offset can also be included in frequency domain child resource dial gauge.
As it can be seen that by using said program, it will be able to carry out resource allocation in the random access channel for Internet of Things cell
When, with reference to the identification information of each Internet of Things cell, the identification information based on each Internet of Things cell is calculated
Obtain corresponding time-domain resource and/or frequency domain resource.In this way, different Internet of Things cells is due to the different identification information of correspondence,
The instruction information of different time-domain resources and/or frequency domain resource is necessarily corresponded to using identical computational methods, and then to adjacent
Internet of Things cell determine different time-domain resource and/or frequency domain resource, so as to ensure that minizone NPRACH resource distributions
Randomization reduces the interference that NPRACH is generated in minizone to greatest extent.
Embodiment two,
On the basis of the explanation of embodiment one, the present embodiment provides specific processing scenes：
It is configured about time-domain position：Determining PRACH resources time-domain position, there are three parameters：Period；Start offset；NPRACH
Number of repetition.Wherein NPRACH periods and number of repetition are to determine that there is no need to close by cell target covering and target capacity
Join the identification information (ID) of Internet of Things cell.
The ID of start offset configuration association Internet of Things cell：Deviant in periodic regime is associated with Internet of Things cell
ID, such as ID mod (num (the NPRACH resource period of the index#1=Internet of Things cells of deviant
starting time<NPRACH resource periodicity))。
Further, it is repeated since NPRACH exists in the time domain, if deviant is nearer, it is possible to generating weight
It is folded, therefore deviant can carry out more sparse jump choosing, such as can be with one bias of every n selection, as n=2, deviant
Meet index=2N*index#1 or (2N+1) * index#1 to increase the interval of deviant value.
It is configured about frequency domain position：Frequency domain position is determined by two parameters：Frequency shift (FS)；Number of subcarriers.Sub-carrier number
Amount is determined that there is no need to be associated with the ID of Internet of Things cell by target capacity.
Frequency shift (FS) configuration association PCID：Frequency offseting value is directly linked PCID, such as the Index=PCID of deviant
Mod (num (effective deviant number)), and selected in effective deviant into row offset value.
Assuming that there are three cells, the physics id of cell 0 is 327, and the physics id of cell 1 is 328, the physics id of cell 2
It is 329.When configuration of territory assume the NPRACH time domain periods be 160ms.Frequency domain configuration NPRACH subcarrier in frequency domain quantity is 12.Then
According to the method for this programme：
For example, referring to Fig. 2, when configuration of territory：2 are divided between time domain biasing selection, (that is, adjacent two cells choosing
The time domain deviant that the instruction information of time domain offset taken is multiplied by corresponding to two obtained values is its final time domain offset).
Cell 0：Time domain biases：327 mod 5=2；The bias selected is 128ms
Cell 1：Time domain biases：328 mod 5=3；The bias selected is 16ms
Cell 2：Time domain biases：329 mod 5=4；The bias selected is 64ms
For example, referring to Fig. 3, frequency domain configuration：
Cell 0：Frequency offsets：327 mod 7=5；The bias selected is 18
Cell 1：Frequency offsets：328 mod 7=6；The bias selected is 34
Cell 2：Frequency offsets：329 mod 7=0；The bias selected is 0
Below by this programme use in narrowband Internet of Things for illustrate, random access channel, that is, NPRACH.
NPRACH is sent using single tone modes, subcarrier spacing 3.75kHz；NPRACH supports time-frequency domain to divide multiplexing, does not prop up
Hold Preamble code division multiplexings；For different community size, 2 kinds of CP length are supported, such as referring to Fig. 4 and Fig. 5, it is corresponding respectively
It is example to support two kinds of length of 66.7us and 266.7us；4 Symbol Group form a NPRACH channel；Each cell
3 sets of PRACH resources are at most can configure, correspond to three kinds of covering grades respectively.Referring to Fig. 6 and Fig. 7, NPRACH channels account on frequency domain
According to 1 3.75kHz subcarrier bandwidth, workable frequency domain resource and frequency domain resource biasing can by broadcast message into
Row configuration.
Further, the resource distribution on NPRACH frequency domains can be carried out by two parameters：prach-
SubcarrierOffset and prach-NumSubcarriers, indicates respectively frequency offsets and frequency domain resource.
Time domain defines and configuration, NPRACH channels carry out resource distribution by four parameters in the time domain：NPRACH resources
Period (NPRACH resource periodicity)；NPRACH resource time domains initial position (NPRACH resource
period starting time)；NPRACH CP length (PRACH CP length)；NPRACH numbers of repetition (Number of
NPRACH repetitions), configuration form is as shown in Figure 8 and Figure 9.
The design of existing NPRACH is wherein it is important that NPRACH no longer supports code point mode to carry out user area
Divide, distinguished fully according to the mode of time-frequency domain, and NPRACH sequences are not superimposed cell scrambling.This will lead to one sternly
The problem of weight, i.e., when the user of different community has used identical NPRACH time-frequency domain resources, and when user is in cell edge,
It will lead to the interference of serious minizone PRACH, it, can will be positioned at cell edge after the method provided using this programme
For being set as the user using different running time-frequency resources, so, interference would not be generated with the user in Intra-cell.
