Description

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

A configured Sidelink resource grant (or called Sidelink configured grant) has at least one associated resource pool, however, the timing of PSCCH (Physical Sidelink Control Channel) or PSCCH (Physical Sidelink shared Channel) in the configured Sidelink grant may not be in the associated resource pool.

For example, a configured proportional link grant includes 3 PSCCH/psch events within one period, as shown in fig. 1, PSCCH/psch event #3 of 3 PSCCH/psch events #1/2/3 of the configured proportional link grant within a certain period T falls within the time domain range of resource pool #2, and PSCCH/psch event #1/2 belongs within the time domain range of resource pool # 1.

In order to improve the reliability and resource utilization rate of data transmission on the sidelink, a HARQ (Hybrid Automatic Repeat reQuest) feedback mechanism is also introduced in the sidelink technology: after receiving the Sidelink data (the Sidelink data is transmitted on the psch, where the psch is scheduled by SCI (Sidelink Control Information) and the SCI is transmitted on PSCCH and/or PSCCH), the Sidelink receiving user may indicate whether the transmission of the Sidelink is successful or failed by feeding back Sidelink HARQ-ACK Information, which is transmitted on PSFCH (physical Sidelink Feedback Channel) resources. In addition, for the control node not working on the 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 Sidelink is successful. For the Control node, the user reports the Sidelink HARQ-ACK information through a PUCCH (Physical Uplink Control Channel) or a PUSCH (Physical Uplink Shared Channel). The position of the PUCCH or PUSCH needs to be determined based on the PSFCH occasion corresponding to the last PSCCH/PSSCH occasion of a CG period.

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

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 2, an information transmission method according to 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,

Therefore, in the information transmission method according to the embodiment of the present invention, the user equipment transmits the sidelink feedback information to the network side equipment serving as the control node through the target resource, where the target resource is determined for a resource belonging to the associated resource set in the sidelink resource group, or the target resource may also be determined only for a resource in the sidelink resource group without being affected by the associated resource set, thereby avoiding that the sidelink feedback information transmission cannot be completed due to the fact that the resource for the sidelink feedback information cannot be determined.

Optionally, the resources belonging to the associated resource set in the sidelink resource group include: at least one of a first Physical Sidelink Control Channel (PSCCH) resource, a first Physical Sidelink Shared Channel (PSSCH) resource, a first PSFCH resource, a second PSCCH resource and a second PSSCH resource;

the target resource is determined by at least one of:

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

a PSFCH resource corresponding to the first PSSCH resource;

the first PSFCH resource;

the second PSCCH resource;

the second PSSCH resource.

For a resource belonging to an associated set of resources in a set of sidelink resources: the target resource can be determined by a PSFCH resource corresponding to a first PSCCH resource belonging to an associated resource set in the sidelink resource group, wherein the first PSCCH resource is a resource belonging to the associated resource set in the sidelink resource group, but the PSFCH resource corresponding to the first PSCCH resource can be unlimited; the target resource can be determined by a PSFCH resource corresponding to a first PSSCH resource belonging to an associated resource set in the sidelink resource group, wherein the first PSSCH resource is a resource belonging to the associated resource set in the sidelink resource group, but the PSFCH resource corresponding to the first PSSCH resource can be unlimited; the target resource may be determined by a first PSFCH resource in the set of sidelink resources that belongs to the set of associated resources; the target resource can be determined by a second PSCCH resource belonging to the associated resource set in the sidelink resource set; the target resource may be determined by a second psch resource in the set of sidelink resources that belongs to the set of associated resources. Of course, the determination may also be determined by any two or more of the PSCCH resource corresponding to the first PSCCH resource, the second PSCCH resource, and the second PSCCH resource.

Optionally, the set of sidelink resources includes: at least one of a third PSCCH resource, a second PSCCH resource, a fourth PSCCH resource, and a fourth PSCCH resource; the target resource is determined by at least one of:

a PSFCH resource corresponding to the third PSCCH resource;

a PSFCH resource corresponding to the third PSSCH resource;

the second PSFCH resource;

the fourth PSCCH resource;

the fourth PSSCH resource.

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

It should be noted that the first PSCCH resource may be the first or xth PSCCH resource in the set of sidelink resources belonging to the associated resource set, X is greater than 1, preferably the last PSCCH resource, for example, the PSCCH resource in the set of sidelink resources belonging to the associated resource set is PSCCH #1, PSCCH #2, and PSCCH #3 in this order, and the first PSCCH resource is PSCCH # 3. Similarly, the first psch resource, the first PSFCH resource, the second PSCCH resource, and the second PSCCH resource may be the first or xth corresponding resource, preferably the last, belonging to the associated resource set in the sidelink resource set. The third PSCCH resource may be a first PSCCH resource or an mth PSCCH resource in the set of sidelink resources, where M is greater than 1, and is preferably a last PSCCH resource, for example, the PSCCH resources in the set of sidelink resources are PSCCH #1, PSCCH #2, and PSCCH #3 in sequence, and the third PSCCH resource is PSCCH #3, where PSCCH #3 may or may not belong to the associated resource set. Similarly, the third psch resource, the second PSCCH resource, the fourth PSCCH resource, and the fourth PSCCH resource may be the first or mth corresponding resource, preferably the last, in the set of sidelink resources.

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

As such, for determining a target resource for a resource in a set of sidelink resources that belongs to an associated resource set, at least one of an associated resource pool, an associated subchannel, and an associated bandwidth segment BWP may be performed as the associated resource set.

In this embodiment, step 201 includes:

and transmitting the sidelink feedback information through the target resource under the condition that at least one resource of the sidelink resource group is a non-associated resource set resource.

Here, in the case where at least one resource of the set of sidelink resources is a non-associated resource set resource, the sidelink feedback information is transmitted via an explicit target resource.

It should also be appreciated that, in this embodiment, the set of sidelink resources is optionally an aperiodic sidelink resource set or a set of resources configured by a configuration sidelink resource grant.

Here, the resource group that can be configured by configuring a sidelink resource grant (configured sidelink grant or sidelink configured grant) is periodic, and the period may be defined by physical time or logical time. Wherein the physical time is a time based on a spatio-temporal order and the logical time is a time only for the sidelink resource order. If the period is defined by physical time and the period is P slot slots, the time interval between the first slot and the last slot in a period is P physical slots, where SCS (subcarrier space) may be calculated according to sidelink SL (sidelink) SCS or 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 the associated resource set, where the subcarrier spacing SCS may be calculated according to the sidelink SL SCS or according to the air interface Uu SCS. In one implementation, both the PSCCH/psch occasion within the resource group configured by the configured sized delayed grant and the PSFCH occasion corresponding to the PSCCH/psch both belong to the time domain of the associated resource set. Wherein, the configured sidelink grant can be set by the network side device.

Therefore, assuming that the resource group configured by the configured sized sidelink grant is used as the sidelink resource group and the associated resource set is the associated resource pool, 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 and belonging to the associated resource pool, e.g., for the configured sidelink grant, the PSFCH resource corresponding to the last PSSCH resource belonging to 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 the sidelink feedback information to the base station. Alternatively, the user equipment may determine a target resource for transmitting the sidelink feedback information based on the PSFCH resource corresponding to the last PSSCH resource in the cycle, for example, for the configured sidelink grant, the PSFCH resource corresponding to the last PSSCH resource is located in slot n (which may belong to the associated resource pool or may not belong to the associated resource pool), and then the PUCCH resource corresponding to n + Y2 is used for transmitting the sidelink feedback information to the base station. Y2 is a parameter for locating a 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 is not described herein again. In addition, in the above description, the resource pool does not belong to the related resource pool, may be in the non-related resource pool, or may not belong to any resource pool.

The non-periodic sidelink resource group may be 1 or more resources dynamically scheduled by the network side device as the control node through the control signaling.

Further, in this embodiment, optionally, the user equipment assumes or desires: 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 link-side resource group and the PSFCH resource corresponding to the first PSCCH resource belong to the same or same group of associated resource sets;

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

Optionally, the user equipment assumes or desires: the set of sidelink resources satisfies at least one of:

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

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

Therefore, the user can determine the target resource and the information needing to be fed back, and the target resource and the information are kept consistent with the understanding of the base station, so that the reliability is improved.

In this embodiment, in order to ensure that the sidelink data transmission is effective and reduce resource waste in consideration of different scenarios, optionally, the method further includes:

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

Optionally, the preset condition comprises at least one of:

a non-associated resource pool resource;

conflict with air interface Uu resources;

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

conflict with sidelink synchronization signal block S-SSB resources.

Wherein, in the condition that the side link bandwidth part is not in the resource pool, the resource pool refers to any resource pool; the conflict with the Uu resource includes: overlapping with downlink DL resources or, overlapping with uplink resources. In this way, when at least one resource of the set of side link resources meets the at least one condition, the user equipment cancels the side link transmission of the at least one resource, or cancels the side link transmission of the set of side link resources, thereby avoiding resource waste. Here, the sidelink transmission includes reception and transmission of sidelink data.

In this embodiment, optionally, the sidelink feedback information is HARQ-ACK information for HARQ-ACK.

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

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

Optionally, when the sidelink resource group has a PSFCH resource corresponding to a PSCCH resource that does not belong to an associated resource set and/or a PSFCH resource corresponding to a PSSCH resource that does not belong to an associated resource set, HARQ-ACK information corresponding to the PSFCH resource 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 resource is determined based on PSCCH resources and/or PSSCH resources belonging to an associated resource set.

Here, for the case that the sidelink resource group has a PSFCH resource corresponding to a PSCCH resource that does not belong to the associated resource set, and/or the sidelink resource group has a PSFCH resource corresponding to a PSSCH resource that does not belong to the associated resource set, three ways of HARQ-ACK information corresponding to the PSFCH resource in the sidelink feedback information are provided: all ACKs or all NACKs; determining based on HARQ-ACK information of PSFCH resources corresponding to PSCCH resources belonging to the associated resource set and/or HARQ-ACK information of PSFCH resources corresponding to PSSCH resources belonging to the associated resource set; is determined based on PSCCH resources and/or PSCCH resources belonging to an associated resource set.

In one implementation, all ACKs or all NACKs are used when the user equipment feeds back sidelink HARQ-ACK information by using a semi-static codebook (type1 codebook).

For example, when a resource group configured by a configured sidelink grant is used as a sidelink resource group, the associated resource group is an associated resource pool, and the configured sidelink grant is associated with resource pool #1 (that is, the associated resource pool is resource pool #1), in 2 PSCCH instances #1/2 within a certain period of the configured sidelink grant, a PSCCH instance corresponding to PSCCH instance #2 falls within a time domain range of resource pool #2, a PSCCH instance corresponding to PSCCH instance #1 belongs to the time domain range of resource pool #1, and a PUCCH corresponding to the configured sidelink grant feeds back HARQ-ACK information of a PSCCH instance corresponding to PSCCH instance #2, the HARQ-ACK information is:

in an aspect, all may be set to ACKs or all may be set to NACKs. At this time, the user equipment feeds back sidelink HARQ-ACK information using a semi-static codebook (type1 codebook).

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

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

In this embodiment, optionally, when there is a PSCCH resource and/or a PSCCH resource that does not belong to an associated resource set in the set of sidelink resources, HARQ-ACK information corresponding to the PSCCH resource and/or PSCCH resource in the sidelink feedback information is ACK or NACK; or,

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

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

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

For example, when a resource group configured by a configured sized sidelink grant is used as a sidelink resource group, the associated resource set is an associated resource pool, and the configured sized sidelink grant is associated with resource pool #1 (that is, the associated resource pool is resource pool #1), in 3 PSCCH or PSCCH #1/2/3 in a certain period of the configured sidelink grant, PSCCH or PSCCH #3 falls within a time domain range of resource pool #2, PSCCH or PSCCH #1 and PSCCH or PSCCH #2 belong to a time domain range of resource pool #1, and when a PUCCH corresponding to the configured sidelink grant feeds back HARQ-ACK information of the 3 PSCCH or PSCCH, PSCCH or PSCCH #3 is set as NACK, and when HARQ-ACK information of the PSCCH or PSCCH # and PSCCH #2 is determined by at least one of the following HARQ ACK-ACK information: corresponding to feedback information carried on the PSFCH resource; a transmission state corresponding to the PSSCH resource; corresponding to the decoding status of the psch resource. At this time, in one implementation, the user equipment feeds back sidelink HARQ-ACK information using a semi-static codebook (type1 codebook).

For another example, when a resource group configured by a configured sidelink grant is used as a sidelink resource group, the associated resource group is an associated resource pool, and the configured sidelink grant is associated with resource pool #1 (that is, the associated resource pool is resource pool #1), in 2 PSCCH or PSCCH ocscan #1/2 in a certain period of the configured sidelink grant, PSCCH or PSCCH ocscan #2 falls within a time domain range of resource pool #2, PSCCH or PSCCH scan #1 belongs within the time domain range of resource pool #1, and when a PUCCH corresponding to the configured sidelink grant feeds back HARQ-ACK information of the 2 PSCCH or PSCCH scan, HARQ-information corresponding to PSCCH or PSCCH ACK #1 may be determined by at least one of: corresponding to feedback information carried on the PSFCH resource; a transmission state corresponding to the PSSCH resource; corresponding to the decoding status of the psch resource. And the HARQ-ACK information corresponding to the PSCCH or psch occasion #2 is set to be the same information as the HARQ-ACK information corresponding to the PSCCH or psch occasion #1, for example, if the PSCCH or psch occasion #1 corresponds to 1bit ACK, the HARQ-ACK information corresponding to the PSCCH or psch occasion #2 is ACK.

In addition, in this embodiment, optionally, in a case that at least one of a PSCCH resource, a PSFCH resource corresponding to the PSCCH resource, and a PSFCH resource corresponding to the psch resource exists in the set of sidelink resources, the sidelink feedback information is used for a SR (Scheduling Request) and/or a BSR (Buffer Status Report).

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

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

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

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

all PSCCH resources in the sidelink resource group;

all PSSCH resources in the sidelink resource group;

all PSFCH resources in the sidelink resource group;

PSFCH resources corresponding to all PSCCH resources in the sidelink resource group;

and PSFCH resources corresponding to all PSSCH resources in the sidelink resource group.

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

Specifically, the preset lengths are different according to different codebooks used by the HARQ-ACK information generated and fed back by the user.

For example, a resource group configured by a configured sized sidelink grant is used as a sidelink resource group, the associated resource set is an associated resource pool, and none of PSCCH events in a certain period of the configured sidelink grant is within a time domain resource range of the associated resource pool, then for the period of the configured sidelink grant, one implementation manner is that, when a user uses a dynamic codebook (type2 codebook) to feed back sidelink HARQ-ACK information, each period corresponds to 1-bit NACK or 1-bit ACK; another implementation manner is that when the user feeds back sidelink HARQ-ACK information by using a semi-static codebook (type1 codebook), each period corresponds to N-bit NACK or N-bit ACK.

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

all PSCCH resources in the sidelink resource group;

all PSSCH resources in the sidelink resource group;

all PSFCH resources in the sidelink resource group;

Here, for the set of sidelink resources configured by the configured sidelink grant, the at least one resource is corresponding to the set of sidelink resources in at least one period; for a dynamically scheduled set of secondary sidelink resources, the at least one resource is within the 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 additional SL resources may be allocated.

For example, the resource group configured by the configured sized sidelink grant is used as a sidelink resource group, the associated resource set is an associated resource pool, the PSFCH event corresponding to the PSCCH or PSCCH in a certain period of the configured sidelink grant is not in the associated resource pool, and its corresponding sidelink HARQ-ACK information, or the corresponding PUCCH/PUSCH is used for or reused for SR and/or BSR. Of course, if the PSCCH or psch event in a certain period of the configured delayed grant is not in the associated resource pool, the corresponding PUCCH/PUSCH is used for or multiplexed with 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 of a PSCCH resource corresponding to a PSCCH resource belonging to an associated resource set and/or HARQ-ACK information of a PSCCH resource corresponding to a PSCCH resource 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 sidelink feedback information may include only information corresponding to the partial resource belonging to the associated resource set, or may include two parts including information corresponding to the partial resource belonging to the associated resource set and information corresponding to the partial resource not belonging to the associated resource set. The HARQ-ACK information may be determined in the above manner, and in this case, one implementation manner is that the user feeds back the HARQ-ACK information by using a dynamic codebook (type2 codebook).

Certainly, considering that target resources of at least two sidelink resource groups of the user equipment may conflict, optionally, if the target resources of the at least two sidelink resource groups of the user equipment satisfy a condition, transmitting sidelink feedback information corresponding to a first sidelink resource group on the target resources; the first side link resource group is a preset side link resource group in the at least two side link resource groups.

Here, the conditions that the target resources of the at least two sidelink resource groups meet include at least one of the same, overlapping, in the same time slot, and short format. Therefore, when the above situation occurs, the target resource is only used to transmit the sidelink feedback information corresponding to the preset sidelink resource group of the at least two sidelink resource groups, so as to avoid the invalid transmission of data.

Optionally, the preset set of sidelink resources is one of the at least two sets of sidelink resources:

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

the lowest side link resource group marks the corresponding side link resource group;

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

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

By definition or configuration, when the above occurs, for the at least two sets of sidelink resources:

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

if the preset sidelink resource group is a sidelink resource group corresponding to the highest confirmation process identification in the at least two sidelink resource groups, that is, the preset sidelink resource group has the largest confirmation process identification in the at least two sidelink resource groups;
