For another example if the sum of the sub-project of project 1 is M11, and the number for the sub-project for needing to distinguish in project 1 is M14≤M11, all sub-projects are distinguished without using random access preamble in project 2, then in the RO period for paging with Number N=M14 of machine access lead type.Wherein, if the K10 sub-project in project 1 shares a random access preamble, K10=M11/M14 or K10=floor (M11/M14) or K10=ceil (M11/M14).

For another example there are multiple sub-projects to share a random access preamble, the random access preamble distributed altogether in project 1 The number of type is M13.The random access preamble index j for being wherein assigned to i-th of sub-project is j=i0+i mod M13.

Optionally, in N=M14, it is with the associated random access preamble index n of j-th of sub-project in project 1 N=i0+floor (k/K10).

In another specific embodiment, if random access preamble is used to distinguish each of three in above-mentioned project In the case where sub-project, the number of random access preamble type can be obtained according to such as under type:

For example, if when random access preamble is for distinguishing three projects, it is assumed that the number of project 1 is M1, or point The number of the random access preamble type of dispensing project 1 is M1, and the number of project 2 is M2, before the random access for distributing to project 2 The number for leading type is M2, and the number of project 3 is M3, or distributing to the number of the random access preamble type of project 3 is M3, then The number of random access preamble type in the RO period at this time is related to three, or related to two or one in three, Such as number N=M1*M2*M3 of the random access preamble type for paging in the RO period.

Optionally, the case where number N=M1*M2*M3 of the random access preamble type for paging within the RO period Under, it is indexed with the associated random access preamble of i-th of sub-project 1 in project 1 are as follows:

I0+i*M2*M3~i0+ (i+1) * M2*M3-1；

It is indexed with the associated random access preamble of j-th of sub-project 2 in project 2 are as follows:

J0+j*M3~j0+ (j+1) * M3-1；

It is n=k0+k with the associated random access preamble of k-th of sub-project 3 index n in project 3,

Wherein, i0 can indicate random access preamble starting index, can also indicate be mapped on corresponding PO with The starting of machine access lead indexes, and can also not define, i.e. expression specified value, and is constant, is also possible to other values, this In without limitation, in addition, the value of i0 can be positive integer, or 0 or negative integer；

Wherein, the value of j0, k0, k1, k2 can be related to the index in the project 1 where project 2, can also be with project 2 Number it is related, can also be related to the number of project 3, can also be related to the number of project 1, can also divide with for paging The initial index of the random access preamble of group is related, the number phase for the random access preamble type that can also be distributed with project 3 It closes, can also be related with the number for the random access preamble type that project 2 is distributed, what can also be distributed with project 1 connects at random The number for entering leading type is related, such as j0=i*M2*M3+i0, and wherein i indicates the index of project 2；Such as k0=i*M2*M3+ j*M3+i0。

For another example 3 middle part molecule project of project can share one if the number of total sub-project of project 3 is M3 Random access preamble, and the number for the sub-project for needing to distinguish by random access preamble in project 3 is M4, M4≤M3, then Number N=M1*M2*M4 of the random access preamble type for paging in the RO period, wherein K4 subitem in project 3 Mesh shares a random access preamble, and K4=M3/M4 can also be K4=floor (M3/M4), can also be K4=ceil (M3/ M4)。

For another example there are multiple sub-projects to share a random access preamble, the random access preamble distributed altogether in project 3 The number of type is M4.The random access preamble index j for being wherein assigned to i-th of sub-project is j=i0+i mod M4.

Optionally, indexing at this time with the associated random access preamble of i-th of sub-project 1 in project 1 is i0+i*M2*M4 ~i0+ (i+1) * M2*M4-1 is j1+j*M4~j1 with the associated random access preamble of j-th of sub-project 2 index in project 2 + (j+1) * M4-1 is n=k1+floor (k/K4) with the associated random access preamble index n of k-th of sub-project in project 3, Wherein k1=i*M2*M4+j*M4+i0, such as j1=i*M2*M4+i0.

For another example if the number of total sub-project of project 2 is M2, in project 3 all sub-projects can without using with Machine access lead is distinguished, and the sub-project in project 2 shares a random access preamble and distinguishes, it assumes that project 2 is for leading to The number for crossing the sub-project that random access preamble distinguishes is M5, and M5≤M2, then in the RO period for paging Number N=M1*M5 of random access preamble type, wherein the K5 sub-project in project 2 shares a random access preamble, K5=M5/M2 can also be K5=floor (M5/M2), can also be K5=ceil (M5/M2).

It is at this time i0+i*M5~i0+ (i+1) * with the associated random access preamble of i-th of sub-project 1 index in project 1 The associated random access preamble index n of j-th of sub-project in M5-1, with project 2 is n=k2+floor (k/K5), wherein k2 =i*M1+i0.

For another example there are multiple sub-projects to share a random access preamble, the random access preamble distributed altogether in project 2 The number of type is M5.The random access preamble index j for being wherein assigned to i-th of sub-project 2 is j=i0+i mod M5.

For another example all sub-projects can not in project 3 and project 2 if the number of total sub-project of project 1 is M1 It is distinguished using random access preamble, the sub-project in project 1 shares a random access preamble and distinguishes, what project 1 was distributed The number of random access preamble type is M6, and M6≤M1, then at this time in RO period or RO set for paging The number of random access preamble type is related to M1, such as the random access preamble for paging in RO period or RO set Number N=M1 of type.Wherein, if the sub-project number for sharing a random access preamble in project 1 is K6, K6=M6/ M1 can also be K6=floor (M6/M1), can also be K6=ceil (M6/M1).

For another example there are multiple sub-projects to share a random access preamble, the random access preamble distributed altogether in project 1 The number of type is N.The random access preamble index j for being wherein assigned to i-th of sub-project 1 is j=i0+i mod N.
