Description

Configuration method of sub-channel, communication node and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for configuring a subchannel, a communication node, and a storage medium.

Background

For Side Link (SL) communication over an unlicensed band, generally, one or more SL Resource pools (hereinafter, referred to as Resource pools) are configured in a Bandwidth Part (BWP) based on a carrier configuration BWP, where one Resource pool may include a plurality of Resource Block sets (RB sets). Typically, a guard band is left between adjacent RB sets to avoid transmissions on different RB sets interfering with each other. When adjacent sets of RBs are both idle (i.e. not occupied by other devices), a higher resource utilization may be achieved if both adjacent sets of RBs and guard bands between them are available for use than if only resources within the sets of RBs are used. However, when a UE uses one RB set, the adjacent RB set may be occupied by other devices, especially other devices of different systems, and a guard band is not generally used in order to avoid interference between the adjacent RB sets. Therefore, how to utilize the guard band is a problem which needs to be solved at present.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

SL communication includes vehicle radio communication technology (V2X) communication, direct communication between User Equipment (UE) and UE (D2D), and the like, and may operate in an authorized spectrum and an Intelligent Transportation System (ITS) spectrum. In the future, it may also operate in unlicensed spectrum.

For SL communication on the licensed band, one or more Resource pools are configured in the BWP, where a Resource pool includes several continuous Resource Blocks (RBs) in the frequency domain, the RBs are divided into one or more sub-channels, each sub-channel includes the same number of RBs, resource allocation of the SL is performed based on the sub-channels in the Resource pool, and each SL transmission occupies one or more continuous sub-channels in the frequency domain.

For SL communication on the unlicensed frequency band, one or more resource pools are configured in the BWP, and one resource pool may contain multiple RB sets. Typically, guard bands are left between adjacent RB sets to avoid transmissions on different RB sets interfering with each other. When adjacent sets of RBs are both idle (i.e. not occupied by other devices), a higher resource utilization may be achieved if both adjacent sets of RBs and guard bands between them are available for use than if only resources within the sets of RBs are used. However, when a UE uses one RB set, the adjacent RB set may be occupied by other devices, especially other devices of different systems, and a guard band is not generally used in order to avoid interference between the adjacent RB sets. Therefore, how to utilize the guard band is a problem which needs to be solved at present.

In addition, in an area where an Occupied Channel Bandwidth (OCB) requirement exists, to meet the OCB requirement, RBs Occupied by User Equipment (UE) are generally distributed discretely in a frequency domain, and these characteristics make it difficult to apply a subchannel continuous in the frequency domain in an authorized frequency band to an unlicensed frequency band. Therefore, how to support frequency domain discrete sub-channels is also a problem to be further solved.

The configuration method of the sub-channel provided in the present application may be applied to SL communication systems based on various wireless communication technologies, for example, SL communication systems based on Long Term Evolution (LTE) technology, fourth generation mobile communication technology (4 th-generation, 4G), fifth generation mobile communication technology (5 th-generation, 5G), LTE and 5G hybrid technology, 5G New Radio (NR) technology, and New communication technology appearing in future communication development, such as sixth generation mobile communication technology (6 th-generation, 6G).

In the embodiment of the present application, a method for configuring a subchannel, a communication node, and a storage medium are provided, which can configure SL resources in an unlicensed frequency band, and improve resource utilization.

First, the concept related to the following embodiments of the present application is explained:

in an embodiment of the present application, a New Radio in Unlicensed Spectrum (NR-U) system defines a plurality of interlaces of RBs, each interlace consisting of equally spaced Common Resource Blocks (CRBs). For example, interleave M E {0,1, \8230, M-1} consists of CRB { M, M + M,2M + M,3M + M, \8230, M is the number of interleaves. Typically, the number of interlaces, M, is 10 and 5 for 15kHz and 30kHz subcarrier spacings, respectively. Of course, the present application also encompasses other interlaces corresponding to subcarrier spacing (e.g., 60khz,120khz,240khz, etc.), and does not limit the number of interlaces, M, corresponding to different subcarriers. BWP i inner interleaving m middle Interleaving Resource Block (IRB)

(i.e. the number of CRBs in interlace m within BWP i) and common resource block->

The relationship between them is as follows:

wherein,

is the starting common resource block of BWP i relative to common resource block 0, μ is the subcarrier spacing index. For example, fig. 1 shows an interleaving diagram with an interleaving number of 5 according to an embodiment. As shown in FIG. 1, interlace 0 consists of CRB {0,5,10, \8230; }, interlace 1 consists of CRB {1,6,11, \8230; }, and so on, interlace 4 consists of CRB {4,9,14, \8230; }. Within a BWP with a starting CRB of CRB 4 and a size of 106 CRBs, the CRB index corresponding to the interleaved resource block {0, 1.. 20} in interlace 0 is {5, 10.. 105}, the CRB index corresponding to the interleaved resource block {0, 1.. 20} in interlace 1 is {6, 11.., 106}, and so on, and the CRB index corresponding to the interleaved resource block {0,1, 2.. 21} in interlace 4 is {4,9, 14.., 109}.

In the present embodiment, for one carrier of a specific subcarrier spacing, the UE may be configured with N-1 Guard Bands (GB), each GB being defined by a starting CRB and a number of CRBs (i.e., the size of the Guard Band), the N-1 GB dividing the carrier into N RB sets. For one carrier, BWP contains an integer number of resource block sets, the starting resource block of BWP

S0 is more than or equal to 0 and is more than or equal to s1 and is more than or equal to N-1. That is, the starting RB of BWP is aligned with the starting RB of resource block set s0, and the ending RB of BWP is aligned with the ending RB of resource block set s 1. Exemplarily, fig. 2 illustrates a carrier, BWP, and RB set according to an embodiment. As shown in FIG. 2, the starting RB of BWP is aligned with the starting RB of RB set1, and the ending RB of BWP is aligned with the ending RB of RB set2, i.e., BWP is comprised of RB set1, GB1, and RB set 2. In the present embodiment, resources within BWP allocated to a UE may be indicated by indicating an interlace index and an RB set index, and the intersection of an interlace and an RB set (including guard bands between allocated adjacent RB sets) is the resources allocated to the UE. In resource allocation, the RB set index goes from 0 to @withinBWP>

Ascending order number and/or number>

Is the number of RB sets within the BWP. Generally, the resource pool is configured within the BWP based on the carrier configuration BWP, which is not excluded by the present application.

Next, a configuration method of sub-channels, a communication node, and technical effects thereof are described.

Fig. 3 is a flowchart illustrating a method for configuring a sub-channel according to an embodiment, where as shown in fig. 3, the method provided in this embodiment is applied to a communication node, and the method includes the following steps.

S110, determining configuration information, wherein the configuration information comprises the subband of the resource pool and the interleaving of the resource pool, or comprises a resource block set (RB set) of the resource pool, the interleaving of the resource pool and the size of a frequency domain unit.

And S120, determining a frequency domain unit according to the configuration information.

S130, configuring sub-channels according to the frequency domain units, wherein a sub-channel comprises a specific number of frequency domain units, and the specific number is determined by a configuration, a pre-configuration or a pre-defined manner.

As can be seen from the step S110, the configuration information can be divided into two cases: one case is that the configuration information includes interleaving of sub-bands of the resource pool and the resource pool; another case is that the configuration information includes RB set of the resource pool, interleaving of the resource pool, and frequency domain unit size. Accordingly, in step S120, the frequency domain unit can be determined regardless of the case to which the configuration information belongs, but the method of determining the frequency domain unit is different for both cases. For ease of understanding, the following examples describe the above two cases in detail, respectively.

In addition, parameters such as L, R, frequency location, frequency domain unit size, subband number, etc. may be determined by configuration, pre-configuration, or predefined manner in the following embodiments of the present application, unless otherwise specified. The specification may be, for example, calculated or obtained by a predefined rule.

In one possible implementation, the configuration information includes a subband of the resource pool and an interlace of the resource pool. Fig. 4 is a flowchart illustrating another configuration method of a sub-channel according to an embodiment, where as shown in fig. 4, the method includes the following steps.

S210, determining configuration information, wherein the configuration information comprises the subband of the resource pool and the interleaving of the resource pool.

In an embodiment, the resource pool comprises at least one sub-band, each sub-band comprising at least one of: RB set, RB set and guard band adjacent to RB set, a set of consecutive RBs.

In one embodiment, the sub-bands are determined based on a resource pool; or the sub-band is determined based on the carrier, the sub-band of the BWP is determined based on the sub-band of the carrier, and the sub-band of the resource pool is determined based on the sub-band of the BWP; or, the sub-band is determined based on BWP, and the sub-band of the resource pool is determined based on the sub-band of BWP; alternatively, the subbands are determined on a carrier basis, and the subbands of the resource pool are determined on a carrier basis.

Interleaving contained in the resource pool (namely, which interleaving is allocated to the resource pool) is configured, preconfigured or predefined, and the frequency domain resource configured or allocated to the resource pool is obtained by taking the intersection of the interleaving contained in the resource pool and the sub-band contained in the resource pool. In general, the resource pool may be defaulted to contain all interlaces. Exemplarily, the subbands are configured based on the resource pool, and the interlaces included in the resource pool are configured, so as to determine the frequency domain resources included in the resource pool, as shown in fig. 5, the configured resource pool includes

subbands

0 and 1, and the configured resource pool includes

interlaces

2 and 3, then the resources shown in the shaded portion in fig. 5 are the resources in the resource pool, that is, the frequency domain resources of the resource pool are all RBs included in

interlaces

2 and 3 in

subbands

0 and 1. As another example, configuring sub-bands based on carriers or BWPs, and then configuring some or all sub-bands to a resource pool, as shown in fig. 6, a carrier or BWP with a sub-carrier spacing of 30kHz contains 3 sub-bands, assuming that the total number of interlaces is 5, the resource pool can be configured to contain sub-bands 0 and 1, and the resource pool contains interlaces 2 and 3, and then the resources shown by the shaded portion in fig. 6 are the resources in the resource pool.

In one embodiment, the rules for determining subbands include at least one of the following 7:

rule 1: a guard band and RB set with small index adjacent to the guard band form a sub-band;

rule 2: a guard band and RB set with large index adjacent to the guard band form a sub-band;

rule 3: the first L RBs in the guard band and the RB set with small index adjacent to the guard band form a sub-band, and L is an integer which is greater than or equal to 0 and less than the number of RBs included in the guard band;

rule 4: the last R RBs in the guard band and the RB set with the large index adjacent to the guard band form a sub-band, and R is an integer which is greater than or equal to 0 and smaller than the number of RBs included in the guard band;

rule 5: k subbands are determined by K-1 frequency positions, and K is a positive integer;

rule 6: determining a sub-band according to at least one of a sub-band size and a sub-band number;

rule 7: each RB set is one subband.

In an embodiment, the determination of which rule or rules to employ to determine the sub-bands may be determined in a configured, pre-configured, or pre-defined manner.

Generally, the resource block sets are numbered from low frequency to high frequency, that is, a resource block set with a small index is a resource block set with low frequency, and a resource block set with a large index is a resource block set with high frequency. In addition, guard bands are also numbered from low frequency to high frequency.

The first example is as follows: the guard band and the RB set with a small index (or the RB set with a low frequency) adjacent to the guard band constitute one sub-band.

The guard band and the RB set with the small index adjacent to the guard band constitute one sub-band, and the last RB set (i.e., the RB set with the largest index in the resource pool) is taken as one sub-band.

Fig. 7 is a diagram illustrating a method for determining subbands according to rule 1 according to an embodiment. As shown in fig. 7, the resource pool contains 3 guard bands, which are hatched in fig. 7, and 4 RB sets, which are numbered 0,1, \ 8230;, 216 within the resource pool. The starting RB and the ending RB of subband 0 are 0 and 55, respectively, i.e., are composed of the first RB set and the first guard band in the resource pool; the starting RB and the ending RB of subband 1 are 56 and 110, respectively, i.e., are composed of the second RB set and the second guard band in the resource pool; the starting and ending RBs of subband 2 are 111 and 166 respectively, i.e. it is composed of the third RB set and the third guard band in the resource pool; the start and stop RBs for subband 3 are 167 and 216, respectively, i.e. consist of the fourth RB set in the resource pool.

Example two: a guard band and an RB set having a large index (or an RB set having a high frequency) adjacent to the guard band constitute one sub-band.

The guard band and the RB set having the largest index adjacent to the guard band constitute one sub-band, and the first RB set (i.e., the RB set having the smallest index in the resource pool) is one sub-band.

Fig. 8 is a diagram illustrating a method for determining subbands according to rule 2 according to an embodiment. As shown in fig. 8, the resource pool contains 3 guard bands, which are hatched in fig. 8, and 4 RB sets, which are numbered 0,1, \ 8230;, 216 within the resource pool. The starting RB and the ending RB of subband 0 are 0 and 49, respectively, i.e., consist of the first RB set in the resource pool; the starting RB and the ending RB of subband 1 are 50 and 105, respectively, i.e., are composed of a first guard band and a second RB set in the resource pool; the starting RB and the ending RB of sub-band 2 are 106 and 160, respectively, i.e., are composed of the second guard band and the third RB set in the resource pool; the start and stop RBs of sub-band 3 are 161 and 216, respectively, i.e. consist of the third guard band and the fourth RB set within the resource pool.

Example three: the first L RBs in the guard band and the RB set having a small index adjacent to the guard band constitute one sub-band, and L is an integer greater than or equal to 0 and less than the number of RBs included in the guard band.

For one resource pool, the first L RBs in one guard band and the RB set with a small index adjacent to the guard band constitute one sub-band, the last RB set is taken as one sub-band, and L is an integer greater than or equal to 0 and less than the number of RBs included in the guard band. Each guard band in the resource pool may correspond to one L value, or all guard bands in the resource pool may correspond to one L value.

Fig. 9 is a diagram illustrating a subband determination according to rule 3 according to an embodiment. As shown in fig. 9, the resource pool includes 2 guard bands and 3 RB sets, L takes the value of 5, and the first 5 RBs and the first RB set of the first guard band constitute one sub-band; the first 5 BR and second RB set of the second guard band form a sub-band; the third RB set is one subband.

In one embodiment, for rule 3, the value of l is determined by configuration, pre-configuration, or pre-defined; or, the value of L is calculated according to the size of the frequency domain unit.

For the case where the value of L is calculated according to the size of the frequency domain unit, one frequency domain unit is all RBs included in one subband in one interlace. For example, the frequency domain unit size is

And each RB, the value of L needs to meet the condition: the RB numbers of the corresponding interweaves of the resource pool in the sub-band consisting of the RB set with small adjacent index and the first L RBs of the guard band are all ^ or>

Is the minimum (or maximum) value of (a). That is, L makes a resource poolThe intersection of each subband and each interlace of the resource pool of (a) contains a number of RBs equal to the configured, pre-configured, or predefined frequency-domain unit size. As shown in fig. 10, it is assumed that the resource pool includes interlaces of interlace 0, interlace 1 and interlace 2 (which interlaces the resource pool includes may be configured, preconfigured or predefined, or the default resource pool includes all interlaces), the guard band GB0 includes 6 RBs, the resource set RB set0 with a small index adjacent to GB0 includes 8 RBs, the numbers of RBs corresponding to interlaces 0,1 and 2 in RB set0 are 1, 1 and 2, respectively, and it is assumed that the frequency domain unit size is 2 RBs, i.e.,' q>

Then the smallest L that makes a sub-band of the first L RBs of RB set0 and GB0 satisfy that the number of RBs (i.e., corresponding frequency domain unit size) contained by

interlaces

0,1 and 2 within that sub-band are each 2 is 2, i.e., L =2.

Example four: and the last R RBs in the guard band and the RB set with the large index adjacent to the guard band form a sub-band, wherein R is an integer which is greater than or equal to 0 and less than the number of RBs included in the guard band.

For one resource pool, the last R RBs in a guard band and the RB set with large index adjacent to the guard band form a sub-band, the first RB set is taken as one sub-band, and R is an integer which is greater than or equal to 0 and less than the number of RBs included in the guard band. Each guard band in the resource pool may correspond to one R value, or all guard bands in the resource pool may correspond to one R value.

In one embodiment, the value of the rule 4, r, is determined by configuration, pre-configuration, or pre-defined means; or, the value of R is calculated according to the size of the frequency domain unit.

For the case where the value of R is calculated according to the size of the frequency domain unit, the calculation method is similar to the method for calculating the value of L according to the size of the frequency domain unit in the third example, and for brevity, details are not repeated here.

Example five: the first L RBs in the guard band and the small-index RB set adjacent to the guard band form a sub-band, the last R RBs in the guard band and the large-index RB set adjacent to the guard band form a sub-band, the RB set of the guard band with the small-index RB set and the first L RBs in the large-index guard band form a sub-band for the RB set with the guard band on both sides, L is an integer which is greater than or equal to 0 and smaller than the number of RBs included in the guard band, and R is an integer which is greater than or equal to 0 and smaller than the number of RBs included in the guard band.

For one resource pool, first L RBs in one guard band and RB sets with small indexes adjacent to the guard band constitute one sub-band, last R RBs in the guard band and RB sets with large indexes adjacent to the guard band constitute one sub-band, and for one guard band, the sum of L and R is an integer less than or equal to the number of RBs included in the guard band. Each guard band in the resource pool may correspond to an L value, or all guard bands in the resource pool correspond to an L value; each guard band in the resource pool may correspond to one R value, or all guard bands in the resource pool may correspond to one R value.

Fig. 11 is a diagram illustrating a method for determining subbands according to rule 3 and rule 4 according to an embodiment. As shown in fig. 11, the resource pool includes 2 guard bands and 3 RB sets, and the first 3 RBs and the first RB set of the first guard band constitute one sub-band (i.e., sub-band 0); the last 2 RBs of the first guard band, the second RB set, and the first 2 RBs of the second guard band constitute one sub-band (i.e., sub-band 1); the last 4 BR and the third RB set of the second guard band constitute one subband (i.e., subband 2).

Example six: k subbands are determined by K-1 frequency positions, and K is a positive integer.

The resource pool is divided into K sub-bands by K-1 frequency positions, and the sub-bands are marked as sub-bands K, K =0,1, \ 8230, K-1, wherein the starting RB of the sub-band K (K is more than 0 and less than or equal to K-1) is the RB corresponding to the frequency position K-1, the ending RB of the sub-band K (K is more than or equal to 0 and less than K-1) is the previous RB of the RB corresponding to the frequency position K, the starting RB of the sub-band 0 is the first RB of the resource pool, and the ending RB of the sub-band K-1 is the last RB of the resource pool.

Fig. 12 is a diagram illustrating a method for determining subbands according to rule 5 according to an embodiment. As shown in fig. 12, the number of RBs in the resource pool (i.e., RB index) is 0,1, \ 8230;, 159, two frequency positions are RB 55 and RB 110, respectively, the start-stop RB of subband 0 is 0 (i.e., the first RB of the resource pool) and 54 (i.e., the previous RB of the RB corresponding to frequency position 0), the start-stop RB of subband 1 is 55 (i.e., the RB corresponding to frequency position 0) and 109 (i.e., the previous RB of the RB corresponding to frequency position 1), and the start-stop RB of subband 2 is 110 (i.e., the RB corresponding to frequency position 1) and 159 (i.e., the last RB of the resource pool), respectively.

In the above method, the RB corresponding to the frequency position is used as the starting RB of the subband with high index, and the RB corresponding to the frequency position may be used as the ending RB of the subband with low index, that is:

the resource pool is divided into sub-bands of K by K-1 frequency positions, and the sub-bands are marked as sub-bands K, K =0,1, \8230, K-1, wherein the starting RB of the sub-band K (K is more than 0 and less than or equal to K-1) is the next RB of the RB corresponding to the frequency position K-1, the ending RB of the sub-band K (K is more than or equal to 0 and less than K-1) is the RB corresponding to the frequency position K, the starting RB of the sub-band 0 is the first RB of the resource pool, and the ending RB of the sub-band K-1 is the last RB of the resource pool.

Fig. 13 is a diagram illustrating another example of determining subbands according to rule 5 according to an embodiment. As shown in fig. 13, the number of RBs in the resource pool (i.e., RB index) is 0,1, \ 8230;, 159, the two frequency positions are RB 55 and RB 110, respectively, the start-stop RB of subband 0 is 0 (i.e., the first RB of the resource pool) and 55 (i.e., the RB corresponding to frequency position 0), the start-stop RB of subband 1 is 56 (i.e., the next RB of the RB corresponding to frequency position 0) and 110 (i.e., the RB corresponding to frequency position 1), and the start-stop RB of subband 2 is 111 (i.e., the next RB of the RB corresponding to frequency position 1) and 159 (i.e., the last RB of the resource pool), respectively.

In one embodiment, the K-1 frequency locations are determined by configuration, pre-configuration, or pre-defined means.

Example seven: the sub-band is determined according to at least one of a sub-band size and a number of sub-bands.

Fig. 17 shows a schematic diagram for determining a sub-band according to rule 7, where a resource pool includes 3 guard bands and 4 RB sets, and RB set0, RB set1, RB set2, and RB set3 correspond to sub-band 0, sub-band 1, sub-band 2, and sub-band 3, respectively, that is, each RB set corresponds to one sub-band.

In all of the above examples, if a resource pool contains only one set of resource blocks, then the set of resource blocks corresponds to one subband.

It should be noted that, the above rule example provides a method for determining a subband based on a resource pool, and similarly, the subband may also be determined based on a carrier or BWP, and only the "resource pool" needs to be replaced by the "carrier or BWP", and if the subband is determined based on the carrier or BWP, it needs to be further configured which subbands are included in the resource pool or which subbands belong to the resource pool. Generally, at least one BWP is configured in one carrier, and at least one resource pool is configured in one BWP, so that, in general, the subbands included in the resource pool are subsets of the subbands included in the BWP, and the subbands included in the BWP are subsets of the subbands included in the carrier, but other situations are not excluded, for example, which subbands in the carrier belong to the resource pool are directly configured, that is, the subbands included in the resource pool are directly configured based on the subbands included in the carrier.

In this application, configuring or pre-configuring certain information may be: configuring, by a network or a base station, information to a UE; alternatively, the UE may be provided with information by other higher layer entities (e.g., the UE's own higher layers, other network entities, etc.).

The method provided by the application can enable or disable through a configuration or pre-configuration mode, or enable the SL channel or signal by using interleaving, wherein enabling means that the method in the application can be adopted, and disabling means that the method in the application (namely, adopting the configuration method of the resource pool in the NR R16 SL or the NR R17 SL) cannot be adopted. By enabling or not enabling the method in the application, the SL communication can be flexibly realized in the region with OCB requirement and the region without OCB requirement.

In general, one or more sets of RBs (possibly also including guard bands between sets of resource blocks) may be configured or pre-configured to belong to a resource pool, one or more interlaces may be configured, pre-configured or pre-defined to belong to a resource pool, or a default resource pool may contain all interlaces, and subchannels contained in the resource pool may be further configured to allocate SL transmission resources on a subchannel basis in the resource pool. It is also possible to configure or pre-configure the starting RB of the resource pool and the number of consecutive RBs contained in the resource pool (the UE expects the starting RB of the resource pool to align with the starting RB of RB set sx, and the ending RB of the resource pool to align with the ending RB of RB set sy, where 0 ≦ sx ≦ sy ≦ N-1, N is the total number of RBs set contained in the carrier or BWP), configure, pre-configure or pre-define the interlaces contained in one resource pool, or default resource pool contains all interlaces, and then further configure the subchannels contained in the resource pool.

S220, determining frequency domain units according to the sub-bands of the resource pool and the interleaving of the resource pool, wherein one frequency domain unit is all RBs included in one sub-band in an interleaving mode.

One frequency domain unit is all RBs included in one interlace within one sub-band, i.e., the frequency domain unit is the intersection of a resource block in one sub-band and a resource block in one interlace.

In one embodiment, the frequency domain units are numbered according to the rule of interleaving first and then sub-band; or, the frequency domain units are numbered according to the rule of first sub-band and then interleaving.

For example, numbering frequency domain units according to the rule of interleaving first and then sub-band includes: and numbering the frequency domain units in the first sub-band according to the ascending order of the interleaving indexes, numbering the frequency domain units in the second sub-band according to the ascending order of the interleaving indexes, and so on until the frequency domain units in all the sub-bands are numbered. Specifically, assume that the resource pool includes K subbands and M interlaces, the frequency domain units in the first subband are sequentially numbered as 0, 1.. And M-1 according to the ascending order of the interlace indexes, the frequency domain units in the second subband are sequentially numbered as M, M + 1.. And 2M-1 according to the ascending order of the interlace indexes, and so on, and the frequency domain units in the K subband are numbered as (K-1) M, (K-1) M + 1..

Specifically, assume that the resource pool includes K subbands and M interlaces, the frequency domain units in the first subband are numbered sequentially as 0,1,.. Am-1 according to the ascending interleaving index, the frequency domain units in the second subband are numbered sequentially as M, M +1,. Am-1, and so on according to the descending interleaving index, and the frequency domain units in the 2K-1 subband are numbered sequentially as (2K-2) M, (2K-2) M +1,. Am, (2K-1) M-1 according to the ascending interleaving index. And in the 2k subband, the frequency domain units are sequentially numbered as (2 k-1) M, (2 k-1) M + 1. Similarly, the ascending order and the descending order in this example may be exchanged, that is, the frequency domain units in the first subband are numbered according to the descending order of the interleaving index, then the frequency domain units in the second subband are numbered according to the ascending order of the interleaving index, and so on according to the ascending order of the subband index, for the subband with even index, the frequency domain units in the subband are numbered according to the descending order of the interleaving index, and for the subband with odd index, the frequency domain units in the subband are numbered according to the ascending order of the interleaving index, until the frequency domain units in all subbands are numbered. The frequency domain units are numbered in the mode, so that the interleaving indexes corresponding to the continuous frequency domain units cannot jump.

For example, numbering frequency domain units according to a rule of first sub-band and then interleaving includes: numbering the frequency domain units in the first interlace according to the subband index ascending order, numbering the frequency domain units in the second interlace according to the subband index ascending order, and so on until numbering is completed on all the frequency domain units in the interlaces. Specifically, assuming that the resource pool includes K subbands and M interlaces, the frequency domain units in the first interlace are sequentially numbered as 0, 1.,. K-1 according to the ascending order of subband indexes, the frequency domain units in the second interlace are sequentially numbered as K, K + 1.,. 2K-1 according to the ascending order of subband indexes, and so on, and the frequency domain units in the M interlace are sequentially numbered as (M-1) K, (M-1) K + 1.,. MK-1 according to the ascending order of subband indexes.

For another example, numbering the frequency domain units according to a rule of first subband and then interleaving includes: the frequency domain units in the first interlace are numbered according to the subband index ascending order, then the frequency domain units in the second interlace are numbered according to the subband index descending order, and so on according to the interlace index ascending order, for interlaces with even indexes, the frequency domain units in the interlaces are numbered according to the subband index ascending order, and for interlaces with odd indexes, the frequency domain units in the interlaces are numbered according to the subband index descending order until the frequency domain units in all interlaces are numbered. Specifically, assuming that the resource pool includes K subbands and M interlaces, the frequency domain units in the first interlace are sequentially numbered as 0, 1.,. K-1 according to the ascending order of subband indexes, the frequency domain units in the second interlace are sequentially numbered as K, K + 1.,. 2K-1 according to the descending order of subband indexes, and so on, and the frequency domain units in the 2M-1 interlace are sequentially numbered as (2M-2) K, (2M-2) K + 1., (2M-1) K-1 according to the ascending order of subband indexes. And in the 2m interleaving, the frequency domain units are sequentially numbered as (2 m-1) K, (2 m-1) K +1, a. Similarly, the ascending order and the descending order in this example may be exchanged, that is, the frequency domain units in the first interlace are numbered according to the descending order of the sub-band index, then the frequency domain units in the second interlace are numbered according to the ascending order of the sub-band index, and so on according to the ascending order of the interlace index, for an interlace with an even index, the frequency domain units in the interlace are numbered according to the descending order of the sub-band index, and for an interlace with an odd index, the frequency domain units in the interlace are numbered according to the ascending order of the sub-band index until the frequency domain units in all interlaces are numbered.

if the union of all sub-channels in the frequency domain resource of the PSSCH spans multiple RB sets, the PSSCH uses RBs in a guard band between the RB sets spanned by the union of all sub-channels in the frequency domain resource of the PSSCH and the RB sets spanned by the union of all sub-channels.

if the first sub-channel of the PSSCH associated with the PSCCH does not span RB sets (i.e., the sub-channel only contains one RB in an RB set), then the frequency domain resources of the PSCCH begin with the first RB of the first sub-channel of the associated PSSCH that does not belong to the guard band

The RBs which do not belong to the guard band and the frequency domain resource of the PSCCH are positioned in one sub-channel; if the first subchannel of the PSSCH associated with the PSCCH spans multiple sets of RBs (i.e., the subchannel includes RBs from the multiple sets of RBs), then the frequency domain resource of the PSCCH is ^ or greater than a predetermined number of RBs from the first subchannel of the associated PSSCH that do not belong to the guardband>
