Description

Information transmission method and equipment

The application is divided application of application date 2020, 1 month and 20 days, application number 2020100675036 and invention creation name "information transmission method and equipment".

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method and apparatus.

Background

One configured sidelink resource grant (configured sidelink grant, or sidelink configured grant) has at least one associated resource pool, however, the PSCCH (Physical Sidelink Control Channel ) or pscsch (Pysical Sidelink Share Channel, physical sidelink shared channel) occasion occsion within configured sidelink grant may not be in the associated resource pool.

For example, configured sidelink grant contains 3 PSCCH/PSSCH occalations in one period, as shown in fig. 1, of the 3 PSCCH/PSSCH occalations #1/2/3 of configured sidelink grant in a certain period T, PSCCH/PSSCH occalation #3 falls within the time domain of resource pool #2, and PSCCH/PSSCH occalation #1/2 falls within the time domain of resource pool # 1.

In order to improve the reliability and resource utilization of data transmission on the sidelink, HARQ (Hybrid Automatic Repeat reQuest ) feedback mechanism is also introduced in the sidelink technology: after the sidelink receiving user receives sidelink data (the sidelink data is transmitted on the PSSCH, wherein the PSSCH is scheduled by SCI (Sidelink Control Information, side link control information), the SCI can confirm the sidelink HARQ-ACK information through feedback side link hybrid automatic repeat request to indicate whether the sidelink transmission is successful or failed, and the sidelink HARQ-ACK is transmitted on PSFCH (Pysical Sidelink Feedback Channel, physical side link feedback channel) resources. In addition, for a control node that is not operating on a Sidelink, the user needs to send the Sidelink HARQ-ACK information to the control node, so that the control node can further determine whether the transmission on the Sidelink is successful. For the control node, the user reports the sidlink HARQ-ACK information through PUCCH (Physical Uplink Control Channel ) or PUSCH (Physical Uplink Shared Channel, physical uplink shared channel). The position of the PUCCH or PUSCH is determined based on the PSFCH occision corresponding to the last PSCCH/PSSCH occision in one CG period.

However, in the example of fig. 1, since PSCCH/pscsch occsion#3 is located at resource pool#2 and CG is associated with resources, there is ambiguity in the last PSCCH/pscsch occsion in the period, as shown in fig. 1, the last PSCCH/pscsch occsion in the period may be PSCCH/pscsch occsion#3 or PSCCH/pscsch occsion#2, and in addition, the last PSCCH/pscsch occsion in each period may vary, so that the time domain position of PUCCH or PUSCH for feedback and the size and content of the feedback sidelink HARQ-ACK information cannot be determined.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 2, an information transmission method in an embodiment of the present invention is applied to a user equipment, and includes:

step 201, transmitting side link feedback information through a target resource; wherein,,

In this way, in the information transmission method of the embodiment of the present invention, the ue transmits the sidelink feedback information to the network side device serving as the control node through the target resource, where the target resource is determined for the resources belonging to the association resource set in the sidelink resource set, or the target resource may not be affected by the association resource set and is determined only for the resources in the sidelink resource set, thereby avoiding the failure of determining the resources for the sidelink feedback information to complete the sidelink feedback information transmission.

Optionally, the resources belonging to the associated resource set in the sidelink resource group include: at least one of a first physical side link control channel, PSCCH, resource, a first physical side link shared channel, PSCCH, resource, a second PSCCH, resource, and a second pscsch resource;

the target resource is determined by at least one of:

a physical sidelink feedback channel, PSFCH, resource corresponding to the first PSCCH resource;

PSFCH resources corresponding to the first PSSCH resources;

the first PSFCH resource;

the second PSCCH resource;

and the second PSSCH resource.

For resources belonging to the associated resource set in the set of sidelink resources: the target resource may be determined by a PSFCH resource corresponding to a first PSCCH resource belonging to the associated resource set in the sidelink resource group, the first PSCCH resource being a resource belonging to the associated resource set in the sidelink resource group, but the PSFCH resource corresponding to the first PSCCH resource may not be limited; the target resource may be determined by a PSFCH resource corresponding to a first PSSCH resource belonging to the associated resource set in the sidelink resource group, the first PSSCH resource being a resource belonging to the associated resource set in the sidelink resource group, but the PSFCH resource corresponding to the first PSSCH resource may not be limited; the target resource may be determined by a first PSFCH resource in the sidelink resource group that belongs to the associated resource set; the target resource may be determined by a second PSCCH resource belonging to the associated resource set in the sidelink resource group; the target resource may be determined by a second PSSCH resource belonging to the associated resource set in the sidelink resource group. Of course, it may also be determined by any two or more of the PSFCH resource corresponding to the first PSCCH resource, the first PSFCH resource, the second PSCCH resource, and the second PSSCH resource.

Optionally, the side link resource group includes: at least one of a third PSCCH resource, a third pscsch resource, a second PSFCH resource, a fourth PSCCH resource, and a fourth PSSCH resource; the target resource is determined by at least one of:

PSFCH resources corresponding to the third PSCCH resources;

PSFCH resources corresponding to the third PSSCH resources;

the second PSFCH resource;

the fourth PSCCH resource;

and the fourth PSSCH resource.

For resources within the sidelink resource group that are not affected by the associated resource set, only for resources within the sidelink resource group: the target resource may be determined by a PSFCH resource corresponding to a third PSCCH resource within the sidelink resource group, which is a resource within the sidelink resource group, but the PSFCH resource corresponding to the third PSCCH resource may not be limited; the target resource may be determined by a PSFCH resource corresponding to a third PSSCH resource within the sidelink resource group, the third PSSCH resource being a resource within the sidelink resource group, but the PSFCH resource corresponding to the third PSSCH resource may not be limited; the target resource may be determined by a second PSFCH resource within the sidelink resource group; the target resource may be determined by a fourth PSCCH resource within the sidelink resource group; the target resource may be determined by a fourth PSSCH resource within the sidelink resource group. Of course, it may also be determined by any two or more of the PSFCH resource corresponding to the third PSCCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource.

It should be appreciated that the first PSCCH resource may be the first or xth PSCCH resource belonging to the associated resource set in the sidelink resource group, X being greater than 1, preferably the last PSCCH resource, e.g. PSCCH resources belonging to the associated resource set in the sidelink resource group are PSCCH #1, PSCCH #2 and PSCCH #3 in that order, the first PSCCH resource being PSCCH #3. Similarly, the first PSSCH resource, the first PSFCH resource, the second PSCCH resource, and the second PSSCH resource may be the first or the xth corresponding resource belonging to the associated resource set in the sidelink resource group, and preferably the last one. The third PSCCH resource may be the first or mth PSCCH resource in the sidelink resource group, where M is greater than 1, and preferably is the last PSCCH resource, e.g., PSCCH resources in the sidelink resource group are pscch#1, pscch#2, and pscch#3 in order, and the third PSCCH resource is pscch#3, where pscch#3 may or may not belong to the associated resource set. Likewise, the third PSSCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource may be the first or mth corresponding resource, preferably the last, in the sidelink resource group, respectively.

Optionally, the associated resource set includes at least one of an associated resource pool, an associated sub-channel and an associated bandwidth part BWP.

As such, for determining target resources for resources belonging to the set of associated resources in the set of sidelink resources, at least one of the pool of associated resources, the associated sub-channel, and the associated bandwidth part BWP may be performed as the set of associated resources.

In this embodiment, step 201 includes:

and transmitting the side link feedback information through the target resource in the case that at least one resource of the side link resource group is a non-associated resource set resource.

Here, for the case that at least one resource of the sidelink resource group is a non-associated resource set resource, sidelink feedback information is transmitted through an explicit target resource.

It should also be appreciated that in this embodiment, the sidelink resource group is optionally a non-periodic sidelink resource group or a resource group configured with sidelink resource grant configuration.

Here, the resource group configurable by the configuration sidelink resource grant (configured sidelink grant or sidelink configured grant) is periodic, and its period may be defined in physical time or in logical time. Wherein the physical time is a time based on a spatio-temporal order and the logical time is a time ordered only for sidelink resources. If the period is defined by physical time and the period is P slots, the time interval between the first slot and the last slot is P physical slots in one period, where SCS (subcarrier spacing) may be calculated according to a Sidelink (SL) SCS or may be calculated according to an air interface Uu SCS. If the period is defined by logic time and the period is Q slots, in one implementation, the time interval between the first slot and the last slot in one period is Q slots, optionally Q sidelink slots in its associated resource set, where the subcarrier spacing SCS may be calculated according to the sidelink SL SCS or may be calculated according to the air interface Uu SCS. In this case, in one implementation, PSCCH/pscsch occsion and PSCCH/pscsch corresponding PSCCH/pscsch occsion in the resource group configured by configured sidelink grant are all within the time domain of the associated resource set. Wherein configured sidelink grant may be set by a network side device.

Thus, assuming that the resource group configured by configured sidelink grant is taken as a side link resource group and the associated resource set is an associated resource pool, the user equipment may determine a target resource for transmitting side link feedback information based on the PSFCH resource corresponding to the last PSSCH resource in the associated resource pool in a period, e.g., for the configured sidelink grant, the PSFCH resource corresponding to the last PSSCH resource in the associated resource pool is located in slot m, and the physical uplink control channel PUCCH resource corresponding to m+y2 is used for transmitting side link feedback information to the base station. Alternatively, the ue may determine the target resource for transmitting the sidelink feedback information based on the PSFCH resource corresponding to the last PSSCH resource in the period, e.g., for the configured sidelink grant, the PSFCH resource corresponding to the last PSSCH resource is located in slot n (may belong to the association resource pool or not), and then the PUCCH resource corresponding to n+y2 is used for transmitting the sidelink feedback information to the base station. Wherein Y2 is a parameter for locating the target resource based on the PSFCH resource corresponding to the PSSCH resource. Of course, the determination method of the target resource is not limited to the above, and will not be described herein. In addition, in the above description, the resource pool does not belong to the associated resource pool, may be in the unassociated resource pool, or may not belong to any resource pool.

Instead of periodic side link resource groups, but the network side device as a control node dynamically schedules 1 or more resources through control signaling.

Further, in this embodiment, optionally, the user equipment assumes or expects: the set of sidelink resources satisfies at least one of:

the side link resource groups belong to the same or the same group of associated resource sets;

the PSFCH resources corresponding to the side link resource group and the first PSCCH resources belong to the same or the same group of associated resource sets;

and the PSFCH resources corresponding to the side link resource group and the first PSSCH resource belong to the same or the same group of associated resource sets.

Alternatively, the user equipment assumes or expects: the set of sidelink resources satisfies at least one of:

PSFCH resources corresponding to the side link resource group and the third PSCCH resource belong to the same or the same group of associated resource sets;

and PSFCH resources corresponding to the side link resource group and the third PSSCH resource belong to the same or the same group of associated resource sets.

Therefore, the user can determine the target resource and the information needing feedback, and keep consistent with the understanding of the base station, thereby improving the reliability.

In this embodiment, in view of different scenarios, to ensure that the sidelink data transmission is efficient, the method may further include:

and canceling the side link transmission of at least one resource of the side link resource group or canceling the side link transmission on the side link resource group under the condition that the at least one resource meets the preset condition.

Optionally, the preset condition includes at least one of:

non-associated resource pool resources;

conflict with air interface Uu resources;

within the sidelink bandwidth part and not belonging to the resource pool;

conflict with the side link synchronization signal block S-SSB resources.

Wherein, in a condition that the side link bandwidth part does not belong to a resource pool, the resource pool refers to any resource pool; conflict with Uu resources then includes: overlapping downlink DL resources or overlapping uplink resources. Thus, in the case that at least one resource of the sidelink resource group meets at least one condition, the ue cancels sidelink transmission on the at least one resource or cancels sidelink transmission on the sidelink resource group, thereby avoiding resource waste. Here, the sidelink transmission includes reception and transmission of sidelink data.

In this embodiment, optionally, the side link feedback information is hybrid automatic repeat request acknowledgement HARQ-ACK information.

The user equipment transmits the HARQ-ACK information to a network-side device, such as a base station or a roadside unit RSU, through a target resource.

In addition, in this embodiment, further, in combination with a specific sidelink data transmission scenario, HARQ-ACK information, i.e., sidelink HARQ-ACK information, reported to the network side device is determined.

Optionally, in the case that the PSFCH resources corresponding to the PSCCH resources not belonging to the associated resource set exist in the sidelink resource group, and/or the PSFCH resources corresponding to the PSSCH resources not belonging to the associated resource set exist, HARQ-ACK information corresponding to the PSFCH resources in the sidelink feedback information is ACK or NACK; or,

the HARQ-ACK information corresponding to the PSFCH resource is determined based on the HARQ-ACK information of the PSFCH resource corresponding to the PSCCH resource belonging to the associated resource set and/or the HARQ-ACK information of the PSFCH resource corresponding to the PSSCH resource belonging to the associated resource set; or,

the HARQ-ACK information corresponding to the PSFCH resources is determined based on PSCCH resources and/or PSSCH resources belonging to an associated resource set.

Here, for the case where there are PSFCH resources corresponding to PSCCH resources not belonging to the associated resource set in the sidelink resource group and/or there are PSFCH resources corresponding to PSSCH resources not belonging to the associated resource set in the sidelink resource group, three manners of HARQ-ACK information corresponding to the PSFCH resources in the sidelink feedback information are provided: all ACKs or all NACKs; determining based on the HARQ-ACK information of PSFCH resources corresponding to PSCCH resources belonging to the associated resource set and/or the HARQ-ACK information of PSFCH resources corresponding to PSSCH resources belonging to the associated resource set; based on PSCCH resources and/or PSSCH resources belonging to an associated resource set.

In one implementation, the feedback method is all ACK or NACK and is applied to the case that the user equipment adopts a semi-static codebook (type 1 codebook) to feed back the sidelink HARQ-ACK information.

For example, regarding the resource group configured by configured sidelink grant as the sidelink resource group, the associated resource set is an associated resource pool, and the configured sidelink grant is associated with the resource pool #1 (i.e., the associated resource pool is the resource pool # 1), among 2 PSCCH occisions #1/2 in a certain period of the configured sidelink grant, the PSCCH occision #2 corresponds to a PSCCH occision that falls within the time domain range of the resource pool #2, the PSCCH occision #1 corresponds to a PSCCH occision that belongs to the time domain range of the resource pool #1, and the configured sidelink grant corresponds to a PUCCH feedback HARQ-ACK information of the PSCCH occision that feeds back the HARQ-ACK information of the PSCCH occision:

In one aspect, all may be set to ACK or all may be set to NACK. At this time, the user equipment feeds back the sidelink HARQ-ACK information using a semi-static codebook (type 1 codebook).

On the other hand, the determination may be based on HARQ-ACK information of a PSFCH resource corresponding to a PSCCH resource belonging to the associated resource pool and/or HARQ-ACK information of a PSFCH resource corresponding to a PSSCH resource belonging to the associated resource pool, specifically, if HARQ-ACK information of a PSFCH resource corresponding to PSCCH occsion#1 is 1bit ACK, HARQ-ACK information of a PSFCH occsion corresponding to PSCCH occsion#2 is 1bit ACK.

In yet another aspect, the determination may be based on PSCCH resources and/or PSSCH resources belonging to an associated resource pool.

In this embodiment, optionally, in a case that the PSCCH resource and/or PSSCH resource not belonging to the associated resource set exists in the sidelink resource group, HARQ-ACK information corresponding to the PSCCH resource and/or PSSCH resource in the sidelink feedback information is ACK or NACK; or,

the HARQ-ACK information corresponding to the PSCCH resource and/or PSSCH resource is determined based on the HARQ-ACK information of the PSCCH resource and/or PSSCH resource belonging to the associated resource set; or,

the HARQ-ACK information corresponding to the PSCCH resources and/or PSSCH resources is determined based on PSCCH resources and/or PSSCH resources belonging to an associated resource set.

Here, for the case that there are PSCCH resources and/or PSSCH resources that do not belong to the associated resource set in the side link resource group, three ways of HARQ-ACK information corresponding to the PSCCH resources and/or PSSCH resources in the side link feedback information are provided: all ACKs or all NACKs; determining based on HARQ-ACK information for PSCCH resources and/or PSSCH resources belonging to an associated resource set; based on PSCCH resources and/or PSSCH resources belonging to an associated resource set.

For example, when the resource group configured by configured sidelink grant is taken as the sidelink resource group, the associated resource set is an associated resource pool, and the configured sidelink grant is associated with the resource pool #1 (i.e., the associated resource pool is the resource pool # 1), among 3 PSCCHs or pscsch occisions #1/2/3 in a certain period of the configured sidelink grant, PSCCHs or pscsch occisions #3 fall within a time domain range of the resource pool #2, PSCCHs or pscsch occisions #1 and PSCCHs or pscsch occisions #2 belong to a time domain range of the resource pool #1, and the PUCCH corresponding to configured sidelink gran feeds back HARQ-ACK information of the 3 PSCCHs or pscsch occisions, HARQ-ACK information corresponding to PSCCHs or pscsch occisions #3 is set to ACK or NACK, PSCCHs or pscsch occisions #1 and pscsch occisions #2 may be determined by at least one of the following contents: corresponding to feedback information carried on PSFCH resources; the transmission state of the corresponding PSSCH resource; corresponding to the decoding status of the PSSCH resource. At this time, one implementation is that the user equipment adopts a semi-static codebook (type 1 codebook) to feed back the sidelink HARQ-ACK information.

For another example, when the resource group configured by configured sidelink grant is taken as the sidelink resource group, the association resource set is an association resource pool, and the configured sidelink grant is associated with the resource pool #1 (i.e., the association resource pool is the resource pool # 1), among 2 PSCCHs or pscsch occisions #1/2 in a certain period of the configured sidelink grant, PSCCH or pscsch occisions #2 fall within a time domain range of the resource pool #2, PSCCH or pscsch occisions #1 belong to a time domain range of the resource pool #1, and the PUCCH corresponding to configured sidelink gran feeds back HARQ-ACK information corresponding to the 2 PSCCHs or pscsch occisions, it may be determined by at least one of the following: corresponding to feedback information carried on PSFCH resources; the transmission state of the corresponding PSSCH resource; corresponding to the decoding status of the PSSCH resource. And the HARQ-ACK information corresponding to PSCCH or pscsch occsion #2 is set to be the same as the HARQ-ACK information corresponding to PSCCH or pscsch occsion #1, if PSCCH or pscsch occsion #1 corresponds to 1bit ACK, the HARQ-ACK information corresponding to PSCCH or pscsch occsion #2 is ACK.

In addition, in this embodiment, optionally, in a case where at least one of a PSCCH resource, a PSSCH resource, a PSFCH resource corresponding to a PSCCH resource, and a PSFCH resource corresponding to a PSSCH resource, which does not belong to the associated resource set, exists in the sidelink resource group, the sidelink feedback information is used for SR (Scheduling Request ) and/or BSR (Buffer Status Report, buffer status report).

Thus, for at least one of the cases that the sidelink resource group has PSCCH resources that do not belong to the associated resource set, the sidelink resource group has PSSCH resources that do not belong to the associated resource set, the sidelink resource group has PSFCH resources corresponding to PSCCH resources that do not belong to the associated resource set, and the sidelink resource group has PSFCH resources corresponding to PSSCH resources that do not belong to the associated resource set, sidelink feedback information transmitted through the target resource is used for SR and/or BSR. Of course, the side link feedback information can multiplex HARQ-ACK information for SR and/or BSR.

For example, the resource group configured by configured sidelink grant is used as a side link resource group, and the associated resource set is an associated resource pool. When a part of PSCCH or PSSCH is not in the associated resource pool in a certain period of configured sidelink grant, the side link feedback information corresponding to the part of PSCCH or PSSCH is HARQ-ACK information, and is also used for SR and/or BSR. Of course, it is also possible to use the PUCCH or PUSCH for transmitting the HARQ-ACK information for SR and/or BSR at the same time, or to use only the PUCCH or PUSCH for transmitting the HARQ-ACK information for SR and/or BSR. In addition, the content of the side link feedback information or the content carried by the PUCCH/PUSCH may be not considered, and the side link feedback information may be used for SR and/or BSR, or the PUCCH or PUSCH may be used for SR and/or BSR.

After receiving the SR and/or BSR, the base station can learn the sidelink transmission status and can allocate additional SL resources.

In this embodiment, optionally, the sidelink feedback information of the sidelink resource group is HARQ-ACK information of an ACK or NACK of a preset length in case at least one of the following resources is a non-associated resource set resource:

all PSCCH resources in the set of side link resources;

all PSSCH resources in the sidelink resource group;

all PSFCH resources in the set of sidelink resources;

PSFCH resources corresponding to all PSCCH resources in the side link resource group;

PSFCH resources corresponding to all PSSCH resources in the side link resource group.

Here, for the set of sidelink resources of the configured sidelink grant configuration, the at least one resource is within at least one period of the set of sidelink resources; for a dynamically scheduled set of primary sidelink resources, the at least one resource is for a set of secondary sidelink resources. For at least one of the above cases, the sidelink feedback information is HARQ-ACK information of a preset length ACK or NACK.

Specifically, the codebook adopted according to the HARQ-ACK information fed back by the user is different, and the preset length is also different.

For example, taking the resource group configured by configured sidelink grant as a side link resource group, taking the associated resource set as an associated resource pool, wherein no PSCCH occision in a certain period of configured sidelink grant is in the time domain resource range of the associated resource pool, for the period of configured sidelink grant, one implementation manner is that when the user adopts a dynamic codebook (type 2 codebook) to feed back the sidelink HARQ-ACK information, each period corresponds to 1bit NACK or 1bit ACK; another implementation is that when the user uses a semi-static codebook (type 1 codebook) to feed back the sidelink HARQ-ACK information, each period corresponds to an N-bit NACK or an N-bit ACK.

In this embodiment, optionally, the sidelink feedback information of the sidelink resource group is used for SR and/or BSR in case at least one of the following resources is a non-associated resource set resource:

all PSCCH resources in the set of side link resources;

all PSSCH resources in the sidelink resource group;

all PSFCH resources in the set of sidelink resources;

Here, for the set of sidelink resources of the configured sidelink grant configuration, the at least one resource is within at least one period of the set of sidelink resources; for a dynamically scheduled set of primary sidelink resources, the at least one resource is for a set of secondary sidelink resources. For at least one of the above cases, the sidelink feedback information is used for SR and/or BSR, so that the network side device knows the sidelink transmission status and can allocate additional SL resources.

For example, the resource group configured by configured sidelink grant is used as a side link resource group, the associated resource set is an associated resource pool, and the PSFCH occision corresponding to the PSCCH or the PSSCH in a certain period of configured sidelink grant is not in the associated resource pool, and the corresponding sidelink HARQ-ACK information, or the corresponding PUCCH/PUSCH is used or reused for SR and/or BSR. Of course, if the PSCCH or PSSCH timing is not in the associated resource pool within a certain period of configured sidelink grant, its corresponding PUCCH/PUSCH is used or multiplexed for SR and/or BSR

It should also be appreciated that in this embodiment, optionally, the HARQ-ACK information is determined based on HARQ-ACK information for PSFCH resources corresponding to PSCCH resources belonging to the associated resource set and/or HARQ-ACK information for PSFCH resources corresponding to PSSCH resources belonging to the associated resource set; or,

The HARQ-ACK information is determined based on PSCCH resources and/or PSSCH resources belonging to an associated resource set.

Here, the HARQ-ACK information transmitted through the target resource as the side link feedback information may include only information corresponding to a part of the resources belonging to the associated resource set, or may be two parts including information corresponding to a part of the resources belonging to the associated resource set and information corresponding to a part of the resources not belonging to the associated resource set. The HARQ-ACK information may be determined in the above manner, and in this case, one implementation is that the user feeds back the HARQ-ACK information using a dynamic codebook (type 2 codebook).

Of course, considering that there may be a conflict between the target resources of at least two sidelink resource groups of the ue, optionally, if the target resources of at least two sidelink resource groups of the ue meet the condition, then the sidelink feedback information corresponding to the first sidelink resource group is transmitted on the target resources; wherein the first sidelink resource group is a preset sidelink resource group in the at least two sidelink resource groups.

Here, the condition that the target resources of the at least two sidelink resource groups satisfy includes at least one of being identical, overlapping, being in identical time slots, and being both short format formats. Thus, when the above situation occurs, the sidelink feedback information corresponding to the preset sidelink resource group in the at least two sidelink resource groups is only transmitted through the target resource, so as to avoid invalid transmission of data.

Optionally, the preset sidelink resource group is one of the at least two sidelink resource groups:

the highest side link resource group identifies the corresponding side link resource group;

the side link resource group corresponding to the lowest side link resource group identifier;

the highest confirmation process identifies the corresponding side link resource group;

the lowest acknowledgement process identifies the corresponding set of sidelink resources.

By definition or configuration, when this occurs, for the at least two sidelink resource groups:

if the preset sidelink resource group is the sidelink resource group corresponding to the highest sidelink resource group identifier in the at least two sidelink resource groups, namely the preset sidelink resource group has the largest sidelink resource group identifier in the at least two sidelink resource groups;

if the preset sidelink resource group is the sidelink resource group corresponding to the lowest sidelink resource group identifier in the at least two sidelink resource groups, namely the preset sidelink resource group has the smallest sidelink resource group identifier in the at least two sidelink resource groups;
