Description

Orthogonal resource allocation method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for allocating orthogonal resources.

Background

In 5G communication, a Physical Uplink Control Channel (PUCCH) is used to transmit Uplink Control Information (UCI). The UCI Information includes Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), scheduling ReQuest (SR), and Channel State Information (CSI).

The PUCCH has multiple formats, wherein format 1 is used for transmitting HARQ-ACK and/or SR information, and occupies multiple PUCCH symbols, which include pilot symbols and data symbols that are alternately arranged. Format 1 allows multiple users to share the same time-frequency resourceThe blocks are multiplexed by orthogonal codes. In the conventional Orthogonal resource allocation, 1 spreading Code (OCC) is selected first, cyclic Shift (CS) is allocated in sequence of serial numbers, and then the next 1 spreading Code is selected in sequence of serial numbers, and Cyclic Shift is allocated in sequence of serial numbers. For example, the distribution order is: (OCC) ₁ ，CS ₁ )，(OCC ₁ ，CS ₂ )，(OCC ₁ ，CS ₃ )，…，(OCC ₂ ，CS ₁ )，(OCC ₂ ，CS ₂ )，(OCC ₂ ，CS ₃ )，…

However, the conventional orthogonal resource allocation method cannot satisfy that no large interference occurs between all users in all scenes, and therefore, how to ensure that the interference between the users in different scenes is as small as possible becomes a problem to be solved urgently.

Detailed Description

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that, if a user performs Inverse Discrete Fourier Transform (IDFT) in the PUCCH subband frequency domain when Timing Advance (TA) or delay spread exists, signal energy of the user is dispersed to CS of other users, for example, as shown in fig. 1 (horizontal axis represents OCC sequence number, vertical axis code CS sequence number, for example, N =7, and N is spreading length), when TA is negative and maximum delay is less than or equal to Cyclic Prefix (CP) length, the dispersion direction of signal energy of orthogonal resources (OCC sequence number 0 and CS sequence number 0) of the user is as shown by an arrow, so that the user may cause interference to other users, and performance of the interfered user may be deteriorated. Of course, if the maximum delay exceeds the CP length, the signal energy of the user will also be dispersed to the OCC where other users are located.

If the user has frequency offset or moving speed (causing doppler frequency spreading), the signal energy of the user will be dispersed to the OCC where other users are located, especially to the user multiplexed on the OCC of the same CS. On the same CS, when the spreading length is not equal to 4, the interfered main user is a neighboring user with the interval of 1, and particularly, the neighboring user on the left side or the right side depends on the positive and negative of the frequency offset; when the spreading length is equal to 4, the interfered primary user is a neighboring user with interval 2.

The embodiment of the invention provides a method, a device and equipment for allocating orthogonal resources. The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

As shown in fig. 2, a method for allocating orthogonal resources provided in an embodiment of the present invention includes:

step 201, a network side device determines an orthogonal resource candidate pattern;

step 202, the network side device allocates orthogonal resources to each user according to the orthogonal resource candidate pattern and the current environment parameter information;

Thus, according to step 201, the network side device first determines an orthogonal resource candidate pattern for allocating orthogonal resources to the user. Since the orthogonal resource candidate pattern is a two-dimensional pattern with a first dimension being an OCC sequence number and a second dimension being a CS sequence number, orthogonal resources can be jointly allocated through two dimensions of OCC and CS. Considering the current communication environment, after step 201, as in step 202, the network side device allocates orthogonal resources to each user according to the orthogonal resource candidate pattern and the current environment parameter information, so that the allocation of the orthogonal resources is more suitable for the current communication scenario, and the inter-user interference is more effectively reduced.

In this embodiment, optionally, the CS sequence number interval of the first orthogonal resource is greater than or equal to 2;

Here, the CS sequence sorting forward direction is a direction in which the CS sequence is from small to large, and the CS sequence sorting reverse direction is a direction in which the CS sequence is from large to small. The CS number interval can be recorded as Δ 1 _i,j ，Δ1 _i,j ＝min(MOD(CS _i -CS _j ,12),12-MOD(CS _i -CS _j 12)), wherein CS _i Is the first CS number, CS _j MOD represents the modulo operation for the second CS number.

As described above, in the orthogonal resource candidate pattern used for orthogonal allocation, the CS sequence number interval is greater than or equal to 2.

Here, the OCC sequence sorting forward direction is the direction from small OCC sequence to large OCC sequence, and the OCC sequence sorting reverse direction is the direction from large OCC sequence to small OCC sequence. OCC number interval can be written as Δ 2 _i,j ，Δ2 _i,j ＝min(MOD(OCC _i -OCC _j ,N),12-MOD(OCC _i -OCC _j N)), wherein, OCC _i Is the fourth OCC number, OCC _j MOD represents the remainder operation, and N is the spreading length.

In this embodiment, the spreading length N1 of the pilot and the spreading length N2 of the data may be different (by 1), so that for the pilot, the OCC number interval is substituted with N1 for Δ 2 _i, j formula, all OCC numbers are [0, N1-1 ]]Within the range; for data, substituting OCC number interval with N2 for Δ 2 _i,j Formula, all OCC numbers are [0, N2-1 ]]Within the range. Of course, the pilot CS sequence number and the data CS sequence number of the same user are equal, and the OCC sequence number is also equal. And, in this embodiment, the number of OCC numbers that can support orthogonal resources to be allocated to a user is equal to X, X = min (N1, N2).

Considering that N1 and N2 may not be equal to 4, may be equal to 4, or only one may be equal to 4 and the other is equal to 3 or 5, the orthogonal resource candidate patterns may be different for different cases.

In this embodiment, optionally, when the pilot spreading length and the data spreading length are not equal to 4, in a group of OCC sequence numbers of the orthogonal resource candidate pattern, the CS sequence numbers of the first orthogonal resource are staggered from each other on two OCC sequence numbers except for the largest OCC sequence number, and an OCC sequence number interval of the two OCC sequence numbers is equal to 1.

Here, the largest OCC number is X-1,x = min (N1, N2). That is, when N1 and N2 are not equal to 4, the first orthogonal resource is located in two OCC numbers having an OCC number interval equal to 1 except that the OCC number is X-1 among the OCC numbers [0,X-1] of the orthogonal resource candidate pattern, and the CS numbers are shifted from each other.

Here, that the CS sequence numbers of the first orthogonal resource are shifted from each other on the two OCC sequence numbers means that all CS sequence numbers corresponding to the first orthogonal resource on the two OCC sequence numbers do not overlap. For example, the two OCC indexes are OCC index p and OCC index q, and if all CS indexes corresponding to the first orthogonal resource on OCC index p are {0,2,4,6,8, 10}, all CS indexes corresponding to the first orthogonal resource on OCC index q are {1,3,5,7,9, 11}, and vice versa.

In this embodiment, it should be noted that, for a first orthogonal resource in the orthogonal resource candidate pattern, if the CS sequence numbers corresponding to the first orthogonal resource satisfy that the CS sequence number intervals are all greater than or equal to 3, the CS sequence numbers of the first orthogonal resource are staggered from each other on two OCC sequence numbers with an OCC sequence number X-1 and an OCC sequence number interval equal to 1. At this time, the OCC number range corresponding to the first orthogonal resource is [0,X-1].

For both N1 and N2 are not equal to 4, optionally, when the maximum value of the pilot spreading length and the data spreading length is an odd number, the OCC sequence number corresponding to the first orthogonal resource includes a first OCC sequence number, or the OCC sequence number corresponding to the first orthogonal resource does not include the first OCC sequence number;

Here, the OCC sequence number corresponding to the first orthogonal resource does not include the first OCC sequence number, and the OCC sequence number of the orthogonal resource candidate pattern may not include the first OCC sequence number, or the OCC sequence number of the orthogonal resource candidate pattern may include the first OCC sequence number, but there is no first orthogonal resource on the first OCC sequence number.

That is, when N1 and N2 are not equal to 4 and the maximum value of N1 and N2 is an odd number, the first OCC number is Y-1, Y = max (N1, N2). If N1= N2 is an odd number, the OCC sequence number range of the orthogonal resource candidate pattern is [0,Y-1], and in the orthogonal resource candidate pattern, a first orthogonal resource is to be allocated to a first OCC sequence number, and the OCC sequence number corresponding to the first orthogonal resource includes the first OCC sequence number; the first orthogonal resource is not configured on the first OCC sequence number, and the OCC sequence number corresponding to the first orthogonal resource does not include the first OCC sequence number. If N1 and N2 are not equal, the OCC sequence number range of the orthogonal resource candidate pattern is [0,X-1], and the OCC sequence number corresponding to the first orthogonal resource in the orthogonal resource candidate pattern does not include the first OCC sequence number.

If the OCC sequence number corresponding to the first orthogonal resource includes the first OCC sequence number, the maximum OCC sequence number corresponding to the first orthogonal resource is equal to the first OCC sequence number;

That is, N1 and N2 are not equal to 4, the maximum value of N1 and N2 is an odd number, and when the OCC sequence number corresponding to the first orthogonal resource includes the first OCC sequence number, the OCC sequence number range corresponding to the first orthogonal resource is [0,Y-1]. In this case, the CS sequence corresponding to the first OCC sequence of the first orthogonal resource and the CS sequence corresponding to the OCC sequence having an OCC sequence interval of 1 from the first OCC sequence may be shifted from each other or may not be shifted from each other. When the OCC sequence number corresponding to the first orthogonal resource does not include the first OCC sequence number, if N1 is not equal to N2, the OCC sequence number range corresponding to the first orthogonal resource is [0,X-1]; if N1 is equal to N2, the OCC number range corresponding to the first orthogonal resource is [0,X-2].

The OCC sequence number corresponding to the first orthogonal resource comprises a first OCC sequence number, a CS sequence number corresponding to the first OCC sequence number of the first orthogonal resource and a CS sequence number corresponding to the OCC sequence number with the OCC sequence number interval of 1, the first OCC sequence number and the CS sequence number are staggered with each other, and the first orthogonal resource on the first OCC sequence number can be distributed together with the first orthogonal resources on other OCC sequence numbers. However, if the two are not mutually staggered, optionally, when the OCC sequence number corresponding to the first orthogonal resource includes the first OCC sequence number, the first orthogonal resource on the first OCC sequence number is allocated at the latest.

That is, when N1 and N2 are not equal to 4, and the maximum value of N1 and N2 is an odd number, if the OCC sequence number corresponding to the first orthogonal resource includes the first OCC sequence number, the first orthogonal resource on the first OCC sequence number is allocated at the latest.

In addition, for N1 and N2 not equal to 4, optionally, when the minimum value of the pilot spreading length and the data spreading length is an odd number and the pilot spreading length and the data spreading length are not equal to each other, the OCC sequence number corresponding to the first orthogonal resource includes a second OCC sequence number, or the OCC sequence number corresponding to the first orthogonal resource does not include the second OCC sequence number;

That is, when X is smaller than Y, and X is an odd number, and Y is an even number, the second OCC sequence number is X-1, the OCC sequence number range of the orthogonal resource candidate pattern is [0,X-1], and in the orthogonal resource candidate pattern, if the first orthogonal resource is allocated on the first OCC sequence number, the OCC sequence number corresponding to the first orthogonal resource includes the second OCC sequence number; if the first orthogonal resource is not configured on the first OCC sequence number, the OCC sequence number corresponding to the first orthogonal resource does not include the second OCC sequence number.

If the OCC sequence number corresponding to the first orthogonal resource includes the second OCC sequence number, the maximum OCC sequence number corresponding to the first orthogonal resource is equal to the second OCC sequence number;

and if the OCC sequence number corresponding to the first orthogonal resource does not comprise the second OCC sequence number, the maximum value of the OCC sequence number corresponding to the first orthogonal resource is equal to the second OCC sequence number minus 1.

That is, N1 and N2 are not equal to 4, and N1 and N2 are not equal and the minimum value is an odd number, when the OCC sequence number corresponding to the first orthogonal resource includes the first OCC sequence number, the OCC sequence number range corresponding to the first orthogonal resource is [0,X-1]; when the OCC sequence number corresponding to the first orthogonal resource does not include the first OCC sequence number, the OCC sequence number range corresponding to the first orthogonal resource is [0,X-2].

And under the condition that the OCC sequence number corresponding to the first orthogonal resource comprises the second OCC sequence number, the first orthogonal resource on the second OCC sequence number is allocated at the latest.

That is, when N1 and N2 are not equal to 4, and N1 and N2 are not equal and the minimum value is an odd number, if the OCC sequence number corresponding to the first orthogonal resource includes the second OCC sequence number, the first orthogonal resource on the second OCC sequence number is allocated at the latest.

Of course, in this embodiment, for the first orthogonal resource of the orthogonal resource candidate pattern, the CS sequence numbers of the first orthogonal resource satisfying the OCC sequence numbers are all staggered from the CS sequence numbers of the OCC sequence numbers with the OCC sequence number interval of 1, and the maximum value of the corresponding OCC sequence numbers of the first orthogonal resource is X-1, which is not described in detail herein.

In addition, in this embodiment, optionally, when at least one of the pilot spreading length and the data spreading length is equal to 4, if intervals of CS sequence numbers on the OCC sequence number corresponding to the first orthogonal resource are both equal to 2, the orthogonal resource candidate pattern is a preset orthogonal resource candidate pattern.

If N1 and N2 are both equal to 4, and the intervals of CS sequence numbers on the OCC sequence number corresponding to the first orthogonal resource are both equal to 2, the predetermined orthogonal resource candidate pattern is as shown in fig. 3 or fig. 4; if only 1 of N1 and N2 is equal to 4, and the other 1 is equal to 3, the predetermined orthogonal resource candidate pattern is as shown in fig. 5 or fig. 6; if only 1 of N1 and N2 is equal to 4, and the other 1 is equal to 5, the predetermined orthogonal resource candidate pattern is as shown in fig. 7 or fig. 8.

wherein the third OCC number is equal to 1 or 2.

That is, in the predetermined orthogonal resource candidate pattern shown in fig. 5 or fig. 6, the first orthogonal resource with the OCC number of 1 or 2 is allocated at the latest. In the same predetermined orthogonal resource candidate pattern of fig. 7 or fig. 8, the first orthogonal resource with

OCC number

1 or 2 is allocated at the latest. Of course, the orthogonal resource with the

OCC number

1 or 2 shown in the figure may be left free, that is, not allocated as the first orthogonal resource.

That is, when N1 and N2 are equal to 4, if the intervals of CS sequence numbers on the OCC sequence numbers corresponding to the first orthogonal resource are not all equal to 2, the OCC sequence number interval between the OCC sequence number a and the OCC sequence number B corresponding to the first orthogonal resource is equal to 2, and the CS sequence numbers of the first orthogonal resource on the OCC sequence number a and the OCC sequence number B are staggered from each other, then both the OCC sequence number a and the OCC sequence number B can be valued in the set [0,3]. For example, the CS sequence numbers of the first orthogonal resource at OCC sequence number 0 and OCC sequence number 2 are staggered from each other.

For a first OCC sequence number group with an OCC sequence number range of [0,3], the first orthogonal resource has two OCC sequence numbers with an OCC sequence number interval equal to 2, and the CS sequence numbers are staggered with each other, wherein the OCC sequence number interval is obtained based on the first OCC sequence number group; and is

Here, the OCC number interval is based on the OCC number range of [0,3]OCC number group calculation of (1), i.e. Δ 2 _i,j In, OCC _i And OCC _j The OCC numbers of (1) all belong to [0,3]. The OCC number interval is based on the OCC number range of [0,2]]OCC number group calculation of (1), i.e. Δ 2 _i,j In, OCC _i And OCC _j The OCC numbers of (1) all belong to [0,2]. In this way, in the first orthogonal resource of the orthogonal resource candidate pattern, the CS numbers of the first orthogonal resource on two OCC numbers having an OCC number interval equal to 2 calculated based on the first OCC number group are shifted from each other, and the CS numbers of the first orthogonal resource on two OCC numbers having an OCC number interval equal to 1 calculated based on the second OCC number group are shifted from each other.

Optionally, when one of the pilot spreading length and the data spreading length is equal to 4 and one is equal to 5, if the intervals of the CS sequence numbers on the OCC sequence numbers corresponding to the first orthogonal resource are not all equal to 2 and are greater than or equal to 2, then the intervals are not equal to 2

Here, the OCC number interval is [0,4] based on the OCC number range]OCC number group calculation of (1), i.e. Δ 2 _i,j In, OCC _i And OCC _j All OCC numbers of [0,4]. The OCC number interval is based on the OCC number range of [0,3]]OCC number group calculation of (1), i.e. Δ 2 _i,j In, OCC _i And OCC _j All OCC numbers belong to [0 ]，3]. In this way, in the first orthogonal resource of the orthogonal resource candidate pattern, the CS numbers of the first orthogonal resources on the two OCC numbers having an OCC number interval equal to 1 calculated based on the third OCC number group are shifted from each other, and the CS numbers of the first orthogonal resources on the two OCC numbers having an OCC number interval equal to 2 calculated based on the fourth OCC number group are shifted from each other.

After the network side device determines the orthogonal resource candidate pattern, step 202 is executed. Optionally, in this embodiment, step 202 includes:

the network side equipment determines an orthogonal resource allocation strategy according to the current environmental parameter information;

Here, the current environmental parameter information may be used to indicate a scene characteristic, that is, indicate that a current scene is a delay spread limited scene (e.g., large delay spread + low frequency, medium speed, and low speed), a moving speed limited scene (e.g., small delay spread + high frequency, medium speed, and high speed, or low frequency, and high speed), a double-limited scene, a limited unknown scene, and the like.

It should be appreciated that, in this embodiment, since the orthogonal resource allocation pattern is a two-dimensional pattern of the OCC dimension and the CS dimension, the orthogonal resource allocation strategy is performed in the first allocation order of the OCC dimension and the second allocation order of the CS dimension.

Optionally, the first allocation order comprises:

That is, when N1 and N2 are not equal to 4, in the current OCC sequence number to be allocated, the OCC sequence number is selected based on the following formula:

and the OCC serial number i is subordinate to an OCC serial number set to be distributed, and the OCC serial number j is subordinate to a distributed OCC serial number set.

At this time, the minimum OCC sequence number interval of the OCC sequence number intervals between the selected OCC sequence number and all allocated OCC sequence numbers is greater than the minimum OCC sequence number interval of the OCC sequence number intervals between other OCC sequence numbers to be allocated and all allocated OCC sequence numbers.

Considering the situation that a plurality of OCC sequence numbers to be allocated with the largest minimum OCC sequence number interval exist, on one hand, the OCC sequence numbers to be allocated can be allocated simultaneously; on the other hand, optionally, the step of selecting the OCC sequence number corresponding to the largest minimum OCC sequence number interval includes:

For example, as shown in fig. 9 (in the figure, a square with a background is a first orthogonal resource, and numbers in the square represent an allocation order, and the smaller the number is, the more preferential the allocation is, the numbers are the same and can be not distinguished from each other), after the first allocated OCC number is 0, the OCC numbers to be allocated are 1 to 6, and by calculating the OCC interval between each OCC number to be allocated and OCC number 0, the OCC interval between OCC number 3 and OCC number 0 is 3, which is larger than the OCC intervals between other OCC numbers to be allocated and OCC number 0, and therefore OCC number 3 is allocated second. Then, in the above manner, OCC sequence number 5 is allocated next time,

OCC sequence numbers

1, 2, and 4 are allocated again, and OCC sequence number 6 is allocated last, that is, the first orthogonal resource on OCC sequence number 6 is allocated latest.

Optionally, the first allocation order comprises:

That is, when N1 and N2 are equal to 4, in the current OCC sequence numbers to be allocated, sequence numbers whose OCC sequence number intervals between the OCC sequence number and all allocated OCC sequence numbers are not equal to 2 are preferentially selected. For example, as shown in fig. 10 or 11 (in the drawing, a square grid with a background is a first orthogonal resource, and numbers in the square grid represent an allocation sequence, the smaller the number is, the more preferentially the number is, the same number may not be distinguished from one another), after the first allocated OCC number is 0, the OCC numbers to be allocated are 1 to 3, and both the OCC number 1 and the OCC interval between the OCC number 3 and the OCC number 0 are not equal to 2, the second allocated OCC number may be 1 or 3.

Here, for the case that the OCC sequence intervals between the plurality of OCC sequences to be allocated and all allocated OCC sequences are not equal to 2, the OCC sequence having the CS sequence different from the CS sequence corresponding to all allocated OCC sequences may be preferentially selected based on the CS sequence on the OCC sequence, as shown in fig. 11, where the second allocated OCC sequence is 1.

Optionally, the first allocation order comprises:

That is, when N1 and N2 are equal to 4 and 3, any one of two OCC sequence numbers having the same CS sequence number is regarded as an unallocated OCC sequence number or a latest allocated OCC sequence number in the current OCC sequence numbers to be allocated. For example, as shown in fig. 12 (in the figure, a square with a background is a first orthogonal resource, and numbers in the square represent an allocation sequence, and the smaller the number is, the more preferential the allocation is, the numbers are the same and can be not distinguished from each other), after the first allocated OCC number is 0, the OCC numbers to be allocated are 1 and 2, the CS numbers corresponding to OCC number 1 and OCC number 2 are the same, and the OCC number 2 is taken as the latest allocated OCC number, then the second allocated OCC number is 1. Of course, the second assigned OCC number may be 3 with OCC number 1 being the latest assigned OCC number.

Optionally, the first allocation order comprises:

OCC numbers

1 or 2 is set as an unassigned or latest assigned OCC number.

That is, when N1 and N2 are equal to 4 and 5, respectively, either

OCC number

1 or 2 is set as the unassigned or latest assigned OCC number. For example, as shown in fig. 13 (in the figure, a square with a background is a first orthogonal resource, and numbers in the square represent an allocation sequence, the smaller the number is, the more preferential the allocation is, the numbers are the same and can be not distinguished from each other), the OCC serial number 1 may be allocated first, the OCC

serial numbers

0 and 3 may be allocated second, and the OCC serial number 2 may be allocated last. Of course, OCC number 1 may be set as the latest OCC number to be allocated.

For the allocation order of the CS dimension, in this embodiment, optionally, the second allocation order includes:

That is, in the current CS sequence numbers to be allocated, the CS sequence numbers are selected based on the following formula:

the CS sequence number i belongs to a set of CS sequence numbers to be distributed, and the CS sequence number j belongs to a set of distributed CS sequence numbers.

At this time, the minimum CS sequence number interval of the CS sequence number intervals between the selected CS sequence number and all allocated CS sequence numbers is greater than the minimum OCC sequence number interval of the OCC sequence number intervals between other CS sequence numbers to be allocated and all allocated CS sequence numbers.

Considering the situation that there are multiple CS sequence numbers to be allocated with the largest minimum CS sequence number interval, on one hand, these CS sequence numbers to be allocated may be allocated simultaneously; on the other hand, optionally, the step of selecting the CS corresponding to the largest CS sequence number interval includes:

if the CS serial numbers corresponding to the largest minimum CS serial number interval comprise a plurality of CS serial numbers, selecting a fourth CS serial number in the plurality of CS serial numbers;

the fourth CS sequence number and the fifth CS sequence number have the smallest interval in the reverse direction of the CS sequence number sorting, and the fifth CS sequence number has the CS sequence number interval equal to the largest CS sequence number interval of the smallest CS sequence number interval.

For example, as shown in fig. 14 (in the figure, a square box with a background is a first orthogonal resource, and numbers in the square box represent an allocation order, and the smaller the number is, the more preferential allocation is, the numbers are the same, and the order cannot be distinguished), after the first allocated CS number is 0, the CS numbers to be allocated are 2,4,6,8, and 10, and by calculating the CS interval between each CS number to be allocated and CS number 0, it can be seen that the CS interval between CS number 6 and OCC number 0 is 6, which is larger than the CS intervals between other CS numbers to be allocated and CS number 0, and therefore, CS number 6 is allocated second. After that, the CS sequence numbers to be allocated are 2,4, 8 and 10, and the CS intervals between the CS sequence numbers to be allocated and the

CS sequence numbers

0 and 6 are calculated, it can be known that the minimum CS sequence number intervals between the

CS sequence numbers

2,4, 8 and 10 and the

CS sequence numbers

0 and 6 are all 2, so that the allocated CS sequence numbers corresponding to the minimum CS sequence number intervals of the

CS sequence numbers

2,4, 8 and 10 are further determined, and if the CS sequence number interval between the CS sequence number 2 and the allocated CS sequence number 0 is the minimum CS sequence number interval 2, the allocated CS sequence number 6 corresponding to the allocated CS sequence number 6, the allocated CS sequence number 8 corresponding to the CS sequence number 4 is the allocated CS sequence number 0 corresponding to the allocated CS sequence number 6, the allocated CS sequence number 10. Then, it can be known that the CS sequence number 2 and the allocated CS sequence number 0 are separated by 2 in the reverse direction of the CS sequence number sorting, the CS sequence number 4 and the allocated CS sequence number 6 are separated by 10 in the reverse direction of the CS sequence number sorting, the CS sequence number 8 and the allocated CS sequence number 6 are separated by 2 in the reverse direction of the CS sequence number sorting, and the CS sequence number 10 and the allocated CS sequence number 0 are separated by 10 in the reverse direction of the CS sequence number sorting, so the

CS sequence numbers

4 and 10 are allocated third, and the

CS sequence numbers

2 and 8 are allocated last.

In this embodiment, optionally, in the first allocation order and the second allocation order, the sequence number of the initial allocation may be predefined or configured, such as the sequence number is the smallest.

As can be seen from the above, in the first positive resource of the orthogonal resource allocation pattern, there may exist a configuration in which the OCC sequence number corresponding to a part of the first orthogonal resource is configured to be the latest assigned OCC sequence number, and therefore in this embodiment, optionally, the step of allocating, by the network side device, the orthogonal resource to each user according to the orthogonal resource allocation policy includes:

That is, in all the first orthogonal resources, except the first orthogonal resource (i.e., the second orthogonal resource) whose corresponding OCC sequence number is configured as the latest assigned OCC sequence number, the orthogonal resource is assigned to each user according to the orthogonal resource assignment policy.

Correspondingly, optionally, after the step of allocating, by the network side device, the orthogonal resource to each user according to the orthogonal resource allocation policy, the method further includes:

That is, for the allocation of the second orthogonal resource, the orthogonal resources are allocated to the users according to the second allocation order on the OCC sequence number corresponding to the second orthogonal resource (that is, the OCC sequence number allocated to the latest allocation).

In this embodiment, the orthogonal resource allocation strategy is jointly implemented based on the first allocation order and the second allocation order.

Optionally, the step of allocating, by the network side device, orthogonal resources to each user according to the orthogonal resource allocation policy includes:

the network side equipment allocates orthogonal resources for the user in a first orthogonal resource on the first initial CS serial number according to a first allocation sequence of OCC dimension;

That is, the first allocation policy requires the network side device to select the first initial CS sequence number first; then, in the first orthogonal resource on the initial CS serial number, allocating orthogonal resources for the user according to the first allocation sequence of the OCC dimension; and after the first orthogonal resource on the first initial CS sequence number is distributed, selecting a first target CS sequence number according to the second distribution sequence of the CS dimension, and distributing orthogonal resources for the user in the first orthogonal resource on the first target CS sequence number according to the first distribution sequence of the OCC dimension until all the first orthogonal resources are distributed.

Here, the first allocation strategy may be applicable to a delay spread limited scenario.

The selection of the first initial CS sequence number may be any selection, such as CS sequence number 0.

For example, as shown in fig. 15 (N =7, N1 and N2 are not equal to 4, the first positive resource at OCC number 6 is allocated at the latest) to 42 users, CS number 0 (i.e., the first initial CS number) is first selected, then the first orthogonal resource corresponding to OCC number 0 is first allocated in the first orthogonal resource at CS number 0, then the first orthogonal resource corresponding to OCC number 4 is second allocated in the first allocation order, the first orthogonal resource corresponding to OCC number 2 is third allocated, and allocation of the first orthogonal resource except OCC number 6 at CS number 0 is completed. Subsequently, based on the CS sequence number 0, the CS sequence number 6 (i.e. the first target CS sequence number) is selected according to the second allocation order, and in the first orthogonal resources on the CS sequence number 6, the first orthogonal resource corresponding to the OCC sequence number 0 (i.e. the 4 th allocated first orthogonal resource in all the first orthogonal resources) is allocated first, then according to the first allocation order, the first orthogonal resource corresponding to the OCC sequence number 4 is allocated second, and the first orthogonal resource corresponding to the OCC sequence number 2 is allocated third, so as to complete the allocation of the first orthogonal resources on the CS sequence number 6 except the OCC sequence number 6. Then, the allocation of the first orthogonal resources other than the OCC number 6 is completed in the CS number 3, the CS number 9, the CS number 2, and the CS number 5 … CS number 10 in this order. And finally, allocating orthogonal resources to the users according to a second allocation sequence on the OCC sequence number configured to be allocated latest (namely the OCC sequence number 6).

the network side equipment allocates orthogonal resources for the user according to a first allocation sequence of OCC dimensions in the first orthogonal resources on the second initial CS sequence number and the third initial CS sequence number;

That is, the second allocation policy requires that the network side device first selects a second initial CS sequence number and a third initial CS sequence number whose CS sequence number interval is equal to 1, and then allocates orthogonal resources to the user in the first orthogonal resources on the second initial CS sequence number and the third initial CS sequence number according to the first allocation sequence of the OCC dimension; after the allocation of the first orthogonal resources on the second initial CS sequence number and the third initial CS sequence number is completed, selecting a second target CS sequence number from the second initial CS sequence number according to the second allocation order of the CS dimensions, and determining a third target CS sequence number whose CS sequence number interval from the second target CS sequence number is equal to 1, thereby allocating orthogonal resources to the user according to the first allocation order again in the first orthogonal resources on the second target CS sequence number and the third target CS sequence number until all the first orthogonal resources are allocated.

Here, the second allocation policy may also apply to a delay spread limited scenario.

The selection of the second initial CS sequence number may be any selection, such as CS sequence number 0.

For example, as shown in fig. 16 (N =7, N1 and N2 are not equal to 4, the first positive resource on occ sequence number 6 is allocated at the latest) for 42 users, CS sequence number 0 (i.e., the second initial CS sequence number) is selected first, and then CS sequence number 1 (i.e., the third initial CS sequence number) whose interval from the CS sequence number of CS sequence number 0 is equal to 1 may be selected accordingly. Then, in the first orthogonal resources on CS sequence number 0 and CS sequence number 1, the first orthogonal resource corresponding to OCC sequence number 0 is allocated first, then according to the first allocation sequence, the first orthogonal resource corresponding to OCC sequence number 3 is allocated second, the first orthogonal resource corresponding to OCC sequence number 5 is allocated third, and the first orthogonal resource corresponding to

OCC sequence numbers

1, 2 and 4 is allocated fourth at the same time, so as to complete the allocation of the first orthogonal resource on CS sequence number 0 except OCC sequence number 6. Subsequently, based on the CS sequence number 0, the CS sequence number 6 (i.e. the second target CS sequence number) and the corresponding CS sequence number 7 (i.e. the third target CS sequence number) are selected according to the second allocation order, and among the first orthogonal resources on the CS sequence number 6 and the CS sequence number 7, the first orthogonal resource corresponding to the OCC sequence number 0 (i.e. the 5 th orthogonal resource among all the first orthogonal resources is allocated first), then according to the first allocation order, the first orthogonal resource corresponding to the OCC sequence number 3 is allocated second, the first orthogonal resource corresponding to the OCC sequence number 5 is allocated third, the first orthogonal resources corresponding to the

OCC sequence numbers

1, 2 and 4 are allocated fourth, so as to complete the allocation of the first orthogonal resources on the CS sequence number 0 except the OCC sequence number 6, and complete the allocation of the first orthogonal resources on the CS sequence numbers 6 and the CS sequence numbers 7 except the OCC sequence number 6. And then the allocation of the first orthogonal resources except the OCC sequence number 6 is completed on the

CS sequence numbers

4 and 5, the

CS sequence numbers

10 and 11, the

CS sequence numbers

2 and 3, and the

CS sequence numbers

8 and 9 in turn. And finally, allocating orthogonal resources to the users according to a second allocation sequence on the OCC sequence number configured to be allocated latest (namely the OCC sequence number 6).

the network side equipment allocates orthogonal resources to the user according to a second allocation sequence of CS dimensions in the first orthogonal resources on the first initial OCC serial number;

after the first orthogonal resource on the first initial OCC sequence number is allocated, the network side device selects a first target OCC sequence number according to the first allocation sequence of the OCC dimensions, and allocates orthogonal resources to the user in the first orthogonal resource on the first target OCC sequence number according to the second allocation sequence of the CS dimensions until all the first orthogonal resources are allocated.

That is, the third allocation policy requires that the network side device first selects the first initial OCC sequence number; then, in the first orthogonal resource on the first initial OCC sequence number, allocating orthogonal resources to the users according to a second allocation sequence; and after the first orthogonal resources on the first initial OCC serial number are distributed, selecting a first target OCC serial number according to the first distribution sequence, and distributing the orthogonal resources to the users in the first orthogonal resources on the first target OCC serial number according to the second distribution sequence until all the first orthogonal resources are distributed.

Here, the third allocation strategy may be applicable to a moving speed limited scenario.

The selection of the first initial OCC sequence number may be any selection, such as OCC sequence number 0.

For example, as shown in fig. 17 (N =7, N1 and N2 are not equal to 4, the first positive resource at OCC number 6 is allocated latest) to 42 users, OCC number 0 (i.e., the first initial OCC number) is first selected, then, the first orthogonal resource corresponding to CS number 0 is first allocated in the first orthogonal resource at OCC number 0, then, according to the second allocation order, the first orthogonal resource corresponding to CS number 6 is second allocated, the first orthogonal resources corresponding to

CS numbers

4 and 10 are third allocated at the same time, the first orthogonal resources corresponding to

CS numbers

2 and 8 are fourth allocated at the same time, and allocation of the first orthogonal resources divided by OCC number 0 is completed. Subsequently, based on the OCC sequence number 0, the OCC sequence number 3 (i.e., the first target OCC sequence number) is selected according to the first allocation order from the OCC sequence numbers having the first orthogonal resources except the OCC sequence number 6, and in the first orthogonal resources on the OCC sequence number 3, the first orthogonal resource corresponding to the CS sequence number 1 (i.e., the first orthogonal resource allocated to the 5 th orthogonal resource in all the first orthogonal resources) is allocated first, then according to the second allocation order, the first orthogonal resource corresponding to the CS sequence number 7 is allocated second, the first orthogonal resources corresponding to the

CS sequence numbers

5 and 11 are allocated third at the same time, the first orthogonal resource corresponding to the

CS sequence numbers

3 and 9 are allocated fourth at the same time, and the allocation of the first orthogonal resource on the OCC sequence number 3 is completed. And then, completing the allocation of the first orthogonal resource on the OCC sequence number 5, the OCC sequence number 1, the OCC sequence number 4 and the OCC sequence number 2 in sequence. And finally, allocating orthogonal resources to the users according to a second allocation sequence on the OCC sequence number configured to be allocated latest (namely the OCC sequence number 6).

the network side equipment selects a fifth target CS sequence number on all OCC sequence numbers in sequence according to the sequence of all OCC sequence numbers selected and the second allocation sequence of CS dimension, allocates orthogonal resources to the user in K2 orthogonal resources of the remaining first orthogonal resources on all OCC sequence numbers until all first orthogonal resources are allocated;

wherein K1 and K2 are integers more than 0.

That is, the fourth distribution policy requires that the network side device first select the second initial OCC sequence number; then, in the first orthogonal resources on the second initial OCC sequence number, allocating K1 first orthogonal resources to the user according to a second allocation sequence; after the allocation of the K1 first orthogonal resources on the second initial OCC sequence number is completed, selecting a second target OCC sequence number according to the first allocation order, and selecting a fourth target CS sequence number according to the second allocation order, so that in the first orthogonal resources on the second target OCC sequence number, the K1 first orthogonal resources are allocated to the user according to the second allocation order with the fourth target CS sequence number as a starting point until all the OCC sequence numbers corresponding to the first orthogonal resources are selected once; and subsequently, according to the sequence in which all the OCC sequence numbers are selected, sequentially selecting a fifth target CS sequence number on each OCC sequence number in the sequence according to the second allocation sequence, and allocating K2 first orthogonal resources of the remaining first orthogonal resources on all the OCC sequence numbers until all the first orthogonal resources are allocated.

Here, the fourth allocation strategy may be applicable to a dual constrained scenario or a constrained unknown scenario.

Wherein, the sum of K1 and K2 can be equal to 12 or less than 12. Of course, if K1 and K2 are later equal to 12, then all the first orthogonal resource allocation is completed; if the sum of K1 and K2 is less than 12, sequentially reselecting a fifth target CS sequence number from all OCC sequence numbers according to the second allocation sequence according to the selected sequence of all OCC sequence numbers, and allocating orthogonal resources to the user from K3 first orthogonal resources of the remaining first orthogonal resources from all OCC sequence numbers. K3 may be equal to either of K1 and K2, or may be different from both. If the sum of K1, K2 and K3 is equal to 12, completing the allocation of all the first orthogonal resources; if not, sequentially reselecting the fifth target CS sequence numbers on all OCC sequence numbers according to the second allocation sequence according to the selected sequence of all OCC sequence numbers until all the first orthogonal resources are allocated.

For example, as shown in fig. 18 (N =7, N1 and N2 are not equal to 4,the first positive resource at OCC number 6 is assigned at the latest, and K1= K2= K3= 2), 42 users are assigned, OCC number 0 (i.e., the second initial OCC number) is first selected, then, the first orthogonal resource corresponding to CS number 0 is first assigned in the first orthogonal resource at OCC number 0, and then, the first orthogonal resource corresponding to CS number 6 is second assigned in the second assignment order. Next, based on OCC sequence number 0, OCC sequence number 3 (i.e., the second target OCC sequence number) is selected in the first allocation order among the OCC sequence numbers having the first orthogonal resources except OCC sequence number 6, and CS sequence number 3 (i.e., the fourth target CS sequence number) is selected in the second allocation order, so that the first orthogonal resource corresponding to CS sequence number 3 (i.e., the 3 rd allocated first orthogonal resource among all the first orthogonal resources) is first allocated in the first orthogonal resource on OCC sequence number 3, starting with CS sequence number 3, and then the first orthogonal resource corresponding to CS sequence number 9 is second allocated in the second allocation order. And then, completing the allocation of 2 (K1) first orthogonal resources on each OCC sequence number sequentially on OCC sequence number 5, OCC sequence number 2, OCC sequence number 1 and OCC sequence number 4. At this time, it can be seen that the sequence in which all OCC numbers corresponding to the first orthogonal resource are selected is: OCC number 0, OCC number 3, OCC number 5, OCC number 2, OCC number 1, OCC number 4. In this way, subsequently, according to the selected sequence of the OCC numbers, 2 (K2) first orthogonal resources are allocated to each OCC number, and at this time, the CS numbers corresponding to the first orthogonal resources are the fifth target CS numbers. And next, similarly, according to the selected sequence of the OCC sequence numbers, respectively allocating 2 (K3) first orthogonal resources on each OCC sequence number, where the CS sequence numbers corresponding to the first orthogonal resources are the fifth target CS sequence numbers. Therefore, the first orthogonal resource except the first orthogonal resource on the OCC number 6 is allocated. And finally, allocating orthogonal resources to the users according to a second allocation sequence on the OCC sequence number configured to be allocated latest (namely the OCC sequence number 6).

In this embodiment, it should also be appreciated that the preset mapping relationship may be one-to-one or many-to-one between the orthogonal resource allocation policy and the environment parameter information. For example, a delay spread limited scenario may apply a first allocation policy and a second allocation policy; a movement speed limited scenario may use a third allocation strategy; the fourth allocation strategy may be applicable to both the dual constrained scenarios and the constrained unknown scenarios.

To sum up, the method of the embodiment of the present invention determines an orthogonal resource candidate pattern for allocating orthogonal resources to users, and allocates orthogonal resources to each user according to the orthogonal resource candidate pattern and current environmental parameter information, so that the allocation of orthogonal resources is more suitable for a current communication scenario, and the inter-user interference is more effectively reduced. Moreover, because the orthogonal resource candidate pattern is a two-dimensional pattern with the first dimension being the OCC serial number and the second dimension being the CS serial number, orthogonal resources can be jointly distributed through the two dimensions of the OCC and the CS, and the interference among users is further reduced.
