Description

[0001] This application is a divisional application of the invention entitled "Information Transmission Method and Device", filed on January 20, 2020, with application number 2020100675036. Technical Field

[0002] This invention relates to the field of communication technology, and in particular to an information transmission method and device. Background Technology

[0003] A configured sidelink grant (or sidelink configured grant) has at least one associated resource pool; however, the timing of the PSCCH (Physical Sidelink Control Channel) or PSSCH (Physical Sidelink Share Channel) within the configured sidelink grant may not be within the associated resource pool.

[0004] For example, a configured sidelink grant may contain 3 PSCCH / PSSCH occasions within a cycle, such as... Figure 1 As shown, within a certain period T, among the three PSCCH / PSSCH occasions #1 / 2 / 3 of the configured sidelink grant, PSCCH / PSSCH occasion #3 falls within the time domain of resource pool #2, while PSCCH / PSSCHoccasion #1 / 2 belong to the time domain of resource pool #1.

[0005] To improve the reliability and resource utilization of data transmission on the sidelink, a HARQ (Hybrid Automatic Repeat reQuest) feedback mechanism is introduced into sidelink technology. After the user receives sidelink data (transmitted on the PSSCH, which is scheduled by the SCI (Sidelink Control Information), and the SCI is transmitted on the PSCCH and / or PSSCH), the user can confirm the sidelink transmission success or failure by sending a sidelink HARQ-ACK message. The sidelink HARQ-ACK is transmitted on the PSFCH (Physical Sidelink Feedback Channel) resource. Furthermore, for control nodes not operating on the sidelink, the user needs to send the sidelink HARQ-ACK message to the control node so that the control node can further determine whether the transmission on the sidelink was successful. For this control node, the user reports Sidelink HARQ-ACK information via PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel). The location of PUCCH or PUSCH needs to be determined based on the PSFCH occasion corresponding to the last PSCCH / PSSCH occasion of a CG cycle.

[0006] However, in such Figure 1 In the example, because PSCCH / PSSCH occasion #3 is located in resource pool #2, and CG is associated with resources, the last PSCCH / PSSCH occasion within this cycle is ambiguous, such as... Figure 1 As shown, the last PSCCH / PSSCH occasion in this cycle can be either PSCCH / PSSCH occasion #3 or PSCCH / PSSCH occasion #2. In addition, the last PSCCH / PSSCH occasion in each cycle may change, so it is impossible to determine the time domain location of the PUCCH or PUSCH used for feedback, as well as the size and content of the sidelink HARQ-ACK information. Summary of the Invention

[0007] This invention provides an information transmission method and device to solve the problem that existing solutions cannot determine the location of resources used for feedback.

[0008] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0009] In a first aspect, embodiments of the present invention provide an information transmission method applied to a user equipment, comprising:

[0010] Feedback information is transmitted via the side link through the target resource; among which...

[0011] The target resource is determined based on resources belonging to the associated resource set in the side link resource group, or the target resource is determined based on resources within the side link resource group.

[0012] Secondly, embodiments of the present invention also provide an information transmission method applied to a network-side device, comprising:

[0013] Obtain the sidelink feedback information of the target resource transmission; among which,

[0014] The target resource is determined based on resources belonging to the associated resource set in the side link resource group, or the target resource is determined based on resources within the side link resource group.

[0015] Thirdly, embodiments of the present invention also provide a user equipment, including:

[0016] The transmission module is used to transmit sidelink feedback information through the target resource; among which,

[0017] The target resource is determined based on resources belonging to the associated resource set in the side link resource group, or the target resource is determined based on resources within the side link resource group.

[0018] Fourthly, embodiments of the present invention also provide a network-side device, including:

[0019] The acquisition module is used to acquire sidelink feedback information of the target resource transmission; among which,

[0020] The target resource is determined based on resources belonging to the associated resource set in the side link resource group, or the target resource is determined based on resources within the side link resource group.

[0021] This invention also provides a user equipment, including a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the information transmission method applied to the user equipment as described above.

[0022] This invention also provides a network-side device, including a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the information transmission method applied to the network-side device as described above.

[0023] This invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the information transmission method applied to a user device as described above, or the steps of the information transmission method applied to a network-side device as described above.

[0024] Thus, in this embodiment of the invention, the user equipment transmits side-link feedback information to the network-side device acting as the control node through the target resource. The target resource is determined for resources belonging to the associated resource set in the side-link resource group. Alternatively, the target resource may be determined only for resources within the side-link resource group, without being affected by the associated resource set. This avoids the inability to complete the transmission of side-link feedback information due to the inability to determine the resource used for side-link feedback information.

[0031] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figure 2 As shown, an information transmission method according to an embodiment of the present invention, applied to a user equipment, includes:

[0033] Step 201: Transmit sidelink feedback information through the target resource; wherein,

[0034] The target resource is determined based on resources belonging to the associated resource set in the side link resource group, or the target resource is determined based on resources within the side link resource group.

[0035] Thus, in the information transmission method of this embodiment of the invention, the user equipment transmits side-link feedback information to the network-side device, which is the control node, through a target resource. The target resource is determined for resources belonging to the associated resource set in the side-link resource group. Alternatively, the target resource may be determined only for resources within the side-link resource group, without being affected by the associated resource set. This avoids the inability to complete the transmission of side-link feedback information due to the inability to determine the resource used for side-link feedback information.

[0036] Optionally, the resources belonging to the associated resource set in the side link resource group include at least one of the following: first physical side link control channel (PSCCH) resources, first physical side link shared channel (PSSCH) resources, first PSFCH resources, second PSCCH resources, and second PSSCH resources.

[0037] The target resource is determined by at least one of the following resources:

[0038] The physical sidelink feedback channel (PSFCH) resource corresponding to the first PSCCH resource;

[0039] The PSFCH resource corresponding to the first PSSCH resource;

[0040] The first PSFCH resource;

[0041] The second PSCCH resource;

[0042] The second PSSCH resource.

[0043] For resources belonging to the associated resource set within a sidelink resource group: the target resource can be determined by the PSFCH resource corresponding to the first PSCCH resource belonging to the associated resource set within the sidelink resource group. The first PSCCH resource is a resource belonging to the associated resource set within the sidelink resource group, but the PSFCH resource corresponding to the first PSCCH resource is not limited. The target resource can also be determined by the PSFCH resource corresponding to the first PSSCH resource belonging to the associated resource set within the sidelink resource group. The first PSSCH resource is a resource belonging to the associated resource set within the sidelink resource group, but the PSFCH resource corresponding to the first PSSCH resource is not limited. Alternatively, the target resource can be determined by the first PSFCH resource belonging to the associated resource set within the sidelink resource group. The target resource can also be determined by the second PSCCH resource belonging to the associated resource set within the sidelink resource group. Of course, it can also be determined by any two or more of the following: the PSFCH resource corresponding to the first PSCCH resource, the PSFCH resource corresponding to the first PSCCH resource, the first PSFCH resource, the second PSCCH resource, and the second PSSCH resource.

[0044] Optionally, the sidelink resource group includes at least one of the following: a third PSCCH resource, a third PSSCH resource, a second PSFCH resource, a fourth PSCCH resource, and a fourth PSSCH resource; the target resource is determined by at least one of the following resources:

[0045] The PSFCH resource corresponding to the third PSCCH resource;

[0046] The PSFCH resource corresponding to the third PSSCH resource;

[0047] The second PSFCH resource;

[0048] The fourth PSCCH resource;

[0049] The fourth PSSCH resource.

[0050] For resources not affected by associated resource sets, but only within the sidelink resource group: the target resource can be determined by the PSFCH resource corresponding to the third PSCCH resource within the sidelink resource group. The third PSCCH resource is a resource within the sidelink resource group, but the PSFCH resource corresponding to the third PSCCH resource is not restricted; the target resource can be determined by the PSFCH resource corresponding to the third PSSCH resource within the sidelink resource group. The third PSSCH resource is a resource within the sidelink resource group, but the PSFCH resource corresponding to the third PSSCH resource is not restricted; the target resource can be determined by the second PSFCH resource within the sidelink resource group; the target resource can be determined by the fourth PSCCH resource within the sidelink resource group; the target resource can be determined by the fourth PSSCH resource within the sidelink resource group. Alternatively, it can be determined by any two or more of the following: the PSFCH resource corresponding to the third PSCCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource.

[0051] It should be understood that the first PSCCH resource can be the first or the Xth PSCCH resource belonging to the associated resource set in the side-link resource group, where X is greater than 1, and preferably the last PSCCH resource. For example, if the PSCCH resources belonging to the associated resource set in the side-link resource group are PSCCH#1, PSCCH#2, and PSCCH#3 in sequence, then the first PSCCH resource is PSCCH#3. Similarly, the first PSSCH resource, the first PSFCH resource, the second PSCCH resource, and the second PSSCH resource can also be the first or the Xth corresponding resource belonging to the associated resource set in the side-link resource group, respectively, and preferably the last one. The third PSCCH resource can be the first or the Mth PSCCH resource in the side-link resource group, where M is greater than 1, and preferably the last PSCCH resource. For example, if the PSCCH resources in the side-link resource group are PSCCH#1, PSCCH#2, and PSCCH#3 in sequence, then the third PSCCH resource is PSCCH#3. In this case, PSCCH#3 may or may not belong to the associated resource set. Similarly, the third PSSCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource can also be the first or the Mth corresponding resource in the sidelink resource group, preferably the last one.

[0052] Optionally, the associated resource set includes at least one of an associated resource pool, an associated sub-channel, and an associated bandwidth portion (BWP).

[0053] Thus, to determine the target resource for a resource belonging to the associated resource set in the side link resource group, at least one of the associated resource pool, associated sub-channel, and associated bandwidth portion BWP can be used as the associated resource set.

[0054] In this embodiment, step 201 includes:

[0055] When at least one resource in the sidelink resource group is a non-associated resource set resource, sidelink feedback information is transmitted through the target resource.

[0056] Here, if at least one resource in the sidelink resource group is a non-associated resource set resource, the sidelink feedback information will be transmitted through a clearly defined target resource.

[0057] It should also be noted that, in this embodiment, optionally, the sidelink resource group is an aperiodic sidelink resource group or a resource group configured with sidelink resource authorization.

[0058] Here, the resource groups that can be configured by the configured sidelink grant (or sidelink-configured grant) are periodic, and their period can be defined by physical time or logical time. Physical time is time based on spatiotemporal order, while logical time is time only for the order of sidelink resources. If the period is defined by physical time and the period is P slots, then within one period, the time interval between the first and last slots is P physical slots, where the subcarrier space (SCS) can be calculated according to the sidelink SL (SCS) or the air interface Uu SCS. If the period is defined by logical time and the period is Q slots, then in one implementation, within one period, the time interval between the first and last slots is Q slots within its associated resource set, optionally Q sidelink slots, where the subcarrier space (SCS) can be calculated according to the sidelink SL SCS or the air interface Uu SCS. In one implementation, the PSCCH / PSSCH occasions and their corresponding PSFCH occasions within the resource group configured by the `configured sidelink grant` both fall within the temporal domain of the associated resource set. The `configured sidelink grant` can be set by the network-side device.

[0059] Therefore, assuming the resource group configured in the configured sidelink grant is considered the sidelink resource group, and the associated resource set is considered the associated resource pool, the user equipment (UE) can determine the target resource for transmitting sidelink feedback information based on the PSFCH resource corresponding to the last PSSCH resource within the period and belonging to the associated resource pool. For example, for this configured sidelink grant, if the PSFCH resource corresponding to the last PSSCH resource within the associated resource pool is located in slot m, then the Physical Uplink Control Channel (PUCCH) resource corresponding to m+Y2 is used to transmit sidelink feedback information to the base station. Alternatively, the UE can determine the target resource for transmitting sidelink feedback information based on the PSFCH resource corresponding to the last PSSCH resource within the period. For example, for this configured sidelink grant, if the PSFCH resource corresponding to the last PSSCH resource is located in slot n (which may or may not belong to the associated resource pool), then the PUCCH resource corresponding to n+Y2 is used to transmit sidelink feedback information to the base station. Here, Y2 is the parameter used to locate the target resource based on the PSFCH resource corresponding to the PSSCH resource. Of course, the method of determining the target resource is not limited to the above, and will not be elaborated further here. Additionally, the above content may not belong to any associated resource pool, but could be in an unassociated resource pool or not belong to any resource pool at all.

[0060] Non-periodic sidelink resource groups are one or more resources that are dynamically scheduled by network-side devices acting as control nodes through control signaling.

[0061] Additionally, in this embodiment, the user equipment optionally assumes or expects that the sidelink resource group satisfies at least one of the following:

[0062] The side-link resource groups belong to the same or the same set of associated resources;

[0063] The side link resource group and the PSFCH resource corresponding to the first PSCCH resource belong to the same or the same group of associated resource sets;

[0064] The side link resource group and the PSFCH resource corresponding to the first PSSCH resource belong to the same or the same set of associated resources.

[0065] Optionally, the user equipment assumes or expects that the sidelink resource group satisfies at least one of the following:

[0066] The side-link resource groups belong to the same or the same set of associated resources;

[0067] The side link resource group and the PSFCH resource corresponding to the third PSCCH resource belong to the same or the same set of associated resources.

[0068] The side link resource group and the PSFCH resource corresponding to the third PSSCH resource belong to the same or the same set of associated resources.

[0069] This allows users to identify target resources and the information that needs to be fed back, and maintain consistency with the base station's understanding, thereby improving reliability.

[0070] In this embodiment, considering different scenarios, to ensure effective data transmission in the side-link and reduce resource waste, the method may optionally further include:

[0071] If at least one resource in the sidelink resource group meets a preset condition, cancel the sidelink transmission of the at least one resource, or cancel the sidelink transmission on the sidelink resource group.

[0072] Optionally, the preset conditions include at least one of the following:

[0073] Unrelated resource pool resources;

[0074] Conflict with Uu air interface resources;

[0075] Within the side link bandwidth portion and not belonging to the resource pool;

[0076] There is a conflict with the S-SSB resource of the side link synchronization signal block.

[0077] In the context of "within the sidelink bandwidth portion and not belonging to a resource pool," the resource pool refers to any resource pool. Conflicts with Uu resources include overlap with downlink DL resources, or overlap with uplink resources. Thus, if at least one resource in the sidelink resource group satisfies at least one of the above conditions, the user equipment will cancel sidelink transmission on that at least one resource, or cancel sidelink transmission on that sidelink resource group, to avoid resource waste. Here, sidelink transmission includes both receiving and sending sidelink data.

[0078] In this embodiment, optionally, the side link feedback information is a hybrid automatic repeat request acknowledgment (HARQ-ACK) message.

[0079] User equipment transmits HARQ-ACK information to network-side devices, such as base stations or roadside units (RSUs), through target resources.

[0080] Furthermore, in this embodiment, the HARQ-ACK information to be reported to the network-side device is determined by combining the specific sidelink data transmission scenario, i.e., the sidelink HARQ-ACK information.

[0081] Optionally, if the sidelink resource group contains a PSFCH resource corresponding to a PSCCH resource that does not belong to the associated resource set, and / or a PSFCH resource corresponding to a PSSCH resource that does not belong to the associated resource set, the HARQ-ACK information corresponding to the PSFCH resource in the sidelink feedback information is ACK or NACK; or,

[0082] 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,

[0083] The HARQ-ACK information corresponding to the PSFCH resource is determined based on the PSCCH and / or PSSCH resources belonging to the associated resource set.

[0084] Here, for cases where a sidelink resource group has a PSFCH resource corresponding to a PSCCH resource that does not belong to the associated resource set, and / or, a sidelink resource group has a PSFCH resource corresponding to a PSSCH resource that does not belong to the associated resource set, three methods are provided for the HARQ-ACK information corresponding to the PSFCH resource in the sidelink feedback information: all ACK or all NACK; 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; determined based on the PSCCH resource and / or PSSCH resource belonging to the associated resource set.

[0085] In one implementation, all values ​​are either ACK or NACK, which is applied when the user equipment uses a semi-static codebook (type 1 codebook) to feed back sidelink HARQ-ACK information.

[0086] For example, if the resource group configured in the configured sidelink grant is used as the sidelink resource group, the associated resource set is used as the associated resource pool, and the configured sidelink grant is associated with resource pool #1 (i.e., the associated resource pool is resource pool #1), in two PSCCHoccasions #1 / 2 within a certain period of the configured sidelink grant, the PSFCH occasion corresponding to PSCCH occasion #2 falls within the time domain range of resource pool #2, and the PSFCH occasion corresponding to PSCCH occasion #1 belongs to the time domain range of resource pool #1, when the PUCCH corresponding to the configured sidelink grant feeds back the HARQ-ACK information for the PSFCH occasion corresponding to PSCCH occasion #2, the HARQ-ACK information is as follows:

[0087] On the one hand, all can be set to ACK or all can be set to NACK. In this case, the user equipment uses a semi-static codebook (type 1 codebook) to feed back sidelink HARQ-ACK information.

[0088] On the other hand, it can be determined based on the HARQ-ACK information of the PSFCH resource corresponding to the PSCCH resource belonging to the associated resource pool, and / or the HARQ-ACK information of the PSFCH resource corresponding to the PSSCH resource belonging to the associated resource pool. Specifically, if the HARQ-ACK information of the PSFCH resource corresponding to PSCCH occasion#1 is 1 bit ACK, then the HARQ-ACK information of the PSFCH occasion corresponding to PSCCH occasion#2 is 1 bit ACK.

[0089] On the other hand, it can be determined based on PSCCH resources and / or PSSCH resources belonging to the associated resource pool.

[0090] In this embodiment, optionally, if the sidelink resource group contains PSCCH resources and / or PSSCH resources that do not belong to the associated resource set, the HARQ-ACK information corresponding to the PSCCH resources and / or PSSCH resources in the sidelink feedback information is ACK or NACK; or,

[0091] 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,

[0092] The HARQ-ACK information corresponding to the PSCCH resource and / or PSSCH resource is determined based on the PSCCH resource and / or PSSCH resource belonging to the associated resource set.

[0093] Here, for cases where a sidelink resource group contains PSCCH resources and / or PSSCH resources that do not belong to the associated resource set, three methods are provided for determining the HARQ-ACK information corresponding to the PSCCH resources and / or PSSCH resources in the sidelink feedback information: all are ACK or all are NACK; determined based on the HARQ-ACK information of PSCCH resources and / or PSSCH resources belonging to the associated resource set; determined based on the PSCCH resources and / or PSSCH resources belonging to the associated resource set.

[0094] For example, if the resource group configured in the configured sidelink grant is used as the sidelink resource group, and the associated resource set is used as the associated resource pool, and the configured sidelink grant is associated with resource pool #1 (i.e., the associated resource pool is resource pool #1), in a certain period of the configured sidelink grant, among the three PSCCH or PSSCH occasions #1 / 2 / 3, if PSCCH or PSSCH occasion #3 falls within the time domain range of resource pool #2, and PSCCH or PSSCH occasion #1 and PSCCH or PSSCH occasion #2 fall within the time domain range of resource pool #1, when the PUCCH corresponding to the configured sidelink grant feeds back the HARQ-ACK information for the three PSCCH or PSSCH occasions, the HARQ-ACK information corresponding to PSCCH or PSSCH occasion #3 is set to ACK or NACK. The PSCCH or PSSCH occasion #1 and PSCCH or PSSCH occasion #2 are also within the time domain range of resource pool #1. The HARQ-ACK information corresponding to occasion#2 can be determined by at least one of the following: feedback information carried on the corresponding PSFCH resource; the transmission status of the corresponding PSSCH resource; and the decoding status of the corresponding PSSCH resource. In this case, one implementation is that the user equipment uses a semi-static codebook (type 1 codebook) to feed back the sidelink HARQ-ACK information.

[0095] For example, if the resource group configured in the configured sidelink grant is used as the sidelink resource group, the associated resource set is used as the associated resource pool, and the configured sidelink grant is associated with resource pool #1 (i.e., the associated resource pool is resource pool #1), in two PSCCH or PSSCH occasions #1 / 2 within a certain period of the configured sidelink grant, if PSCCH or PSSCH occasion #2 falls within the time domain range of resource pool #2, and PSCCH or PSSCH occasion #1 falls within the time domain range of resource pool #1, when the PUCCH corresponding to the configured sidelink grant feeds back the HARQ-ACK information for the two PSCCH or PSSCH occasions, the HARQ-ACK information corresponding to PSCCH or PSSCH occasion #1 can be determined by at least one of the following: the feedback information carried on the corresponding PSFCH resource; the transmission status of the corresponding PSSCH resource; and the decoding status of the corresponding PSSCH resource. The HARQ-ACK information corresponding to PSCCH or PSSCH occasion#2 will be set to the same information as the HARQ-ACK information corresponding to PSCCH or PSSCH occasion#1. For example, if PSCCH or PSSCH occasion#1 corresponds to 1 bit ACK, then the HARQ-ACK information corresponding to PSCCH or PSSCH occasion#2 will be ACK.

[0096] In addition, in this embodiment, optionally, if the side link resource group has at least one of the following: PSCCH resource, PSSCH resource, PSFCH resource, PSCCH resource corresponding to PSFCH resource, and PSSCH resource corresponding to PSFCH resource that does not belong to the associated resource set, the side link feedback information is used for SR (Scheduling Request) and / or BSR (Buffer Status Report).

[0097] Thus, for at least one of the following situations: a sidelink resource group contains a PSCCH resource that does not belong to the associated resource set; a sidelink resource group contains a PSSCH resource that does not belong to the associated resource set; a sidelink resource group contains a PSFCH resource that does not belong to the associated resource set; a sidelink resource group contains a PSFCH resource corresponding to a PSCCH resource that does not belong to the associated resource set; and a sidelink resource group contains a PSFCH resource corresponding to a PSSCH resource that does not belong 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 reuse HARQ-ACK information for SR and / or BSR.

[0098] For example, the resource group configured in the configured sidelink grant can be used as the sidelink resource group, and the associated resource set can be used as the associated resource pool. When some PSCCHs or PSSCHs are not in the associated resource pool during a certain period of the configured sidelink grant, the sidelink feedback information corresponding to those PSCCHs or PSSCHs is HARQ-ACK information, which is also used for SR and / or BSR. Of course, the PUCCH or PUSCH that transmits the HARQ-ACK information can also be used for SR and / or BSR, or only the PUCCH or PUSCH that transmits the HARQ-ACK information can be used for SR and / or BSR. Alternatively, the content of the sidelink feedback information or the content carried by the PUCCH / PUSCH can be ignored, and the sidelink feedback information can be used for SR and / or BSR, or the PUCCH or PUSCH can be used for SR and / or BSR.

[0099] Once the base station receives the SR and / or BSR, it can understand the sidelink transmission status and allocate additional SL resources.

[0100] 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 group is a HARQ-ACK message of a preset length of ACK or NACK:

[0101] All PSCCH resources in the side link resource group;

[0102] All PSSCH resources in the side link resource group;

[0103] All PSFCH resources in the side link resource group;

[0104] The PSFCH resources corresponding to all PSCCH resources in the side link resource group;

[0105] The PSFCH resources corresponding to all PSSCH resources in the side link resource group.

[0106] Here, for a sidelink resource group configured by a configured sidelink grant, the at least one resource corresponds to at least one period of that sidelink resource group; for a dynamically scheduled primary sidelink resource group, the at least one resource corresponds to that primary sidelink resource group. In at least one of the above cases, the sidelink feedback information is a HARQ-ACK message with a preset length of ACK or NACK.

[0107] Specifically, the preset length varies depending on the codebook used for the HARQ-ACK information generated by the user.

[0108] For example, if the resource group configured in the configured sidelink grant is used as the sidelink resource group and the associated resource set is used as the associated resource pool, and the PSCCH occasions in a certain period of the configured sidelink grant are not within the time domain resource range of the associated resource pool, then for that period of the configured sidelink grant, one implementation is that when the user uses a dynamic codebook (type 2 codebook) to feed back sidelink HARQ-ACK information, each period corresponds to 1 bit NACK or 1 bit ACK; another implementation is that when the user uses a semi-static codebook (type 1 codebook) to feed back sidelink HARQ-ACK information, each period corresponds to N bit NACK or N bit ACK.

[0109] 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 group is used for SR and / or BSR:

[0110] All PSCCH resources in the side link resource group;

[0111] All PSSCH resources in the side link resource group;

[0112] All PSFCH resources in the side link resource group;

[0113] The PSFCH resources corresponding to all PSCCH resources in the side link resource group;

[0114] The PSFCH resources corresponding to all PSSCH resources in the side link resource group.

[0115] Here, for a sidelink resource group configured by a configured sidelink grant, the at least one resource corresponds to at least one period of that sidelink resource group; for a dynamically scheduled single sidelink resource group, the at least one resource corresponds to that single sidelink resource group. In at least one of the above cases, the sidelink feedback information is used for SR and / or BSR to enable network-side devices to understand the sidelink transmission status and allocate additional SL resources.

[0116] For example, the resource group configured in a configured sidelink grant can be used as the sidelink resource group, and the associated resource set can be used as the associated resource pool. If the PSFCH occasion corresponding to the PSCCH or PSSCH of this configured sidelink grant is not in the associated resource pool within a certain period, the corresponding sidelink HARQ-ACK information, or the corresponding PUCCH / PUSCH, can be used or reused for SR and / or BSR. Conversely, if the PSCCH or PSSCH occasion of this configured sidelink grant is not in the associated resource pool within a certain period, the corresponding PUCCH / PUSCH can be used or reused for SR and / or BSR.

[0117] It should also be understood that, in this embodiment, optionally, the HARQ-ACK information 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,

[0118] The HARQ-ACK information is determined based on PSCCH resources and / or PSSCH resources belonging to the associated resource set.

[0119] Here, the HARQ-ACK information transmitted through the target resource as side-link feedback information may include only the information corresponding to the resources belonging to the associated resource set, or it may include two parts: information corresponding to the resources belonging to the associated resource set and information corresponding to the resources not belonging to the associated resource set. This HARQ-ACK information can be determined in the manner described above. In this case, one implementation is that the user uses a dynamic codebook (type2 codebook) to feed back the HARQ-ACK information.

[0120] Of course, considering that the target resources of at least two side link resource groups of the user equipment may conflict, optionally, if the target resources of at least two side link resource groups of the user equipment meet the conditions, the side link feedback information corresponding to the first side link resource group is transmitted on the target resource; wherein, the first side link resource group is a preset side link resource group among the at least two side link resource groups.

[0121] Here, the target resources of at least two sidelink resource groups must meet at least one of the following conditions: identical, overlapping, located in the same time slot, and both being short format. Thus, in the event of such a situation, the sidelink feedback information corresponding to the preset sidelink resource group in the at least two sidelink resource groups will only be transmitted through that target resource to avoid invalid data transmission.

[0122] Optionally, the preset sidelink resource group is one of the following among the at least two sidelink resource groups:

[0123] The highest-level sidelink resource group identifier corresponds to the sidelink resource group;

[0124] The lowest-level sidelink resource group identifier corresponds to the sidelink resource group;

[0125] The sidelink resource group corresponding to the highest acknowledgment process identifier;

[0126] The sidelink resource group corresponding to the lowest acknowledgment process identifier.

[0127] By defining or configuring, when the above situation occurs, for the at least two side-link resource groups:

[0128] If the preset sidelink resource group is the sidelink resource group corresponding to the highest sidelink resource group identifier among the at least two sidelink resource groups, that is, the preset sidelink resource group has the largest sidelink resource group identifier among the at least two sidelink resource groups;

[0129] If the preset sidelink resource group is the sidelink resource group corresponding to the lowest sidelink resource group identifier among the at least two sidelink resource groups, that is, the preset sidelink resource group has the smallest sidelink resource group identifier among the at least two sidelink resource groups.

[0130] If the preset side link resource group is the side link resource group corresponding to the highest confirmation process ID among the at least two side link resource groups, that is, the preset side link resource group has the highest confirmation process ID among the at least two side link resource groups;

[0131] If the preset sidelink resource group is the sidelink resource group corresponding to the lowest acknowledgment process ID among the at least two sidelink resource groups, that is, the preset sidelink resource group has the lowest acknowledgment process ID among the at least two sidelink resource groups.

[0132] Subsequently, on the target resource, the following information is transmitted: the sidelink feedback information corresponding to the sidelink resource group with the highest sidelink resource group identifier, the sidelink feedback information corresponding to the sidelink resource group with the lowest sidelink resource group identifier, the sidelink feedback information corresponding to the sidelink resource group with the highest acknowledgment process identifier, or the sidelink feedback information corresponding to the sidelink resource group with the lowest acknowledgment process identifier. Of course, the implementation of this preset sidelink resource group can also be limited in other ways, which will not be listed here.

[0133] In summary, the information transmission method of this invention involves a user equipment transmitting sidelink feedback information to a network-side device acting as a control node via a target resource. This target resource is determined for resources belonging to an associated resource set within the sidelink resource group. Alternatively, the target resource may be determined solely for resources within the sidelink resource group, regardless of the associated resource set. This avoids the inability to determine the resource used for the sidelink feedback information, thus preventing the transmission of the sidelink feedback information from failing. Furthermore, the specific content of the sidelink feedback information is defined for specific scenarios, enabling the network-side device to understand the sidelink transmission status and perform subsequent processing.

[0134] like Figure 3 As shown, an embodiment of the present invention provides an information transmission method applied to a network-side device, comprising:

[0135] Step 301: Obtain the sidelink feedback information for the target resource transmission; wherein,

[0136] The target resource is determined based on resources belonging to the associated resource set in the side link resource group, or the target resource is determined based on resources within the side link resource group.

[0137] In the information transmission method of this invention, the network-side device obtains side-link feedback information through a target resource. The target resource is determined for resources belonging to the associated resource set in the side-link resource group. Alternatively, the target resource may be determined only for resources within the side-link resource group, regardless of the associated resource set. This avoids the inability to complete the transmission of side-link feedback information due to the inability to determine the resource used for side-link feedback information.

[0138] Optionally, the resources belonging to the associated resource set in the side link resource group include at least one of the following: first physical side link control channel (PSCCH) resources, first physical side link shared channel (PSSCH) resources, first PSFCH resources, second PSCCH resources, and second PSSCH resources.

[0139] The target resource is determined by at least one of the following resources:

[0140] The physical sidelink feedback channel (PSFCH) resource corresponding to the first PSCCH resource;

[0141] The PSFCH resource corresponding to the first PSSCH resource;

[0142] The first PSFCH resource;

[0143] The second PSCCH resource;

[0144] The second PSSCH resource.

[0145] For resources belonging to the associated resource set within a sidelink resource group: the target resource can be determined by the PSFCH resource corresponding to the first PSCCH resource belonging to the associated resource set within the sidelink resource group. The first PSCCH resource is a resource belonging to the associated resource set within the sidelink resource group, but the PSFCH resource corresponding to the first PSCCH resource is not limited. The target resource can also be determined by the PSFCH resource corresponding to the first PSSCH resource belonging to the associated resource set within the sidelink resource group. The first PSSCH resource is a resource belonging to the associated resource set within the sidelink resource group, but the PSFCH resource corresponding to the first PSSCH resource is not limited. Alternatively, the target resource can be determined by the first PSFCH resource belonging to the associated resource set within the sidelink resource group. The target resource can also be determined by the second PSCCH resource belonging to the associated resource set within the sidelink resource group. Of course, it can also be determined by any two or more of the following: the PSFCH resource corresponding to the first PSCCH resource, the PSFCH resource corresponding to the first PSCCH resource, the first PSFCH resource, the second PSCCH resource, and the second PSSCH resource.

[0146] Optionally, the side link resource group includes at least one of the following: third PSCCH resource, third PSSCH resource, second PSFCH resource, fourth PSCCH resource, and fourth PSSCH resource;

[0147] The target resource is determined by at least one of the following resources:

[0148] The PSFCH resource corresponding to the third PSCCH resource;

[0149] The PSFCH resource corresponding to the third PSSCH resource;

[0150] The second PSFCH resource;

[0151] The fourth PSCCH resource;

[0152] The fourth PSSCH resource.

[0153] For resources not affected by associated resource sets, but only within the sidelink resource group: the target resource can be determined by the PSFCH resource corresponding to the third PSCCH resource within the sidelink resource group. The third PSCCH resource is a resource within the sidelink resource group, but the PSFCH resource corresponding to the third PSCCH resource is not restricted; the target resource can be determined by the PSFCH resource corresponding to the third PSSCH resource within the sidelink resource group. The third PSSCH resource is a resource within the sidelink resource group, but the PSFCH resource corresponding to the third PSSCH resource is not restricted; the target resource can be determined by the second PSFCH resource within the sidelink resource group; the target resource can be determined by the fourth PSCCH resource within the sidelink resource group; the target resource can be determined by the fourth PSSCH resource within the sidelink resource group. Alternatively, it can be determined by any two or more of the following: the PSFCH resource corresponding to the third PSCCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource.

[0154] It should be understood that the first PSCCH resource can be the first or the Xth PSCCH resource belonging to the associated resource set in the side-link resource group, where X is greater than 1, and preferably the last PSCCH resource. For example, if the PSCCH resources belonging to the associated resource set in the side-link resource group are PSCCH#1, PSCCH#2, and PSCCH#3 in sequence, then the first PSCCH resource is PSCCH#3. Similarly, the first PSSCH resource, the first PSFCH resource, the second PSCCH resource, and the second PSSCH resource can also be the first or the Xth corresponding resource belonging to the associated resource set in the side-link resource group, respectively, and preferably the last one. The third PSCCH resource can be the first or the Mth PSCCH resource in the side-link resource group, where M is greater than 1, and preferably the last PSCCH resource. For example, if the PSCCH resources in the side-link resource group are PSCCH#1, PSCCH#2, and PSCCH#3 in sequence, then the third PSCCH resource is PSCCH#3. In this case, PSCCH#3 may or may not belong to the associated resource set. Similarly, the third PSSCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource can also be the first or the Mth corresponding resource in the sidelink resource group, preferably the last one.

Those skilled in the art will understand that... Figure 6 The user equipment structure shown does not constitute a limitation on the user equipment. The user equipment may include more or fewer components than shown, or combine certain components, or have different component arrangements. In embodiments of the present invention, the user equipment includes, but is not limited to, mobile phones, tablet computers, laptop computers, PDAs, vehicle terminals, wearable devices, and pedometers.

[0337] The radio frequency unit 601 is used to transmit sidelink feedback information through the target resource; wherein...

[0338] The target resource is determined by at least one of the following: the physical sidelink feedback channel PSFCH resource corresponding to the first physical sidelink control channel PSCCH resource, the PSFCH resource corresponding to the first physical sidelink shared channel PSSCH resource, the first PSFCH resource, the second PSCCH resource, and the second PSSCH resource.

[0339] The target resource is determined by at least one of the PSFCH resource corresponding to the third PSCCH resource, the PSFCH resource corresponding to the third PSSCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource, wherein the third PSCCH resource, the third PSSCH resource, the second PSFCH resource, the fourth PSCCH resource, and the fourth PSSCH resource are resources within the sidelink resource group.

[0340] As can be seen, the user equipment transmits sidelink feedback information to the network-side device acting as the control node through the target resource. The target resource is determined for resources belonging to the associated resource set in the sidelink resource group. Alternatively, the target resource may be determined only for resources within the sidelink resource group, regardless of the associated resource set. This avoids the inability to complete the transmission of sidelink feedback information due to the inability to determine the resource used for sidelink feedback information.

[0341] It should be understood that, in this embodiment of the invention, the radio frequency unit 601 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink data from the base station and processes it with the processor 610; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 601 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc. Furthermore, the radio frequency unit 601 can also communicate with networks and other devices through a wireless communication system.

[0343] The audio output unit 603 can convert audio data received by the radio frequency unit 601 or the network module 602 or stored in the memory 609 into audio signals and output them as sound. Furthermore, the audio output unit 603 can also provide audio output related to specific functions performed by the user equipment 600 (e.g., call signal reception sound, message reception sound, etc.). The audio output unit 603 includes a speaker, a buzzer, and a receiver, etc.

[0344] Input unit 604 is used to receive audio or video signals. Input unit 604 may include a graphics processing unit (GPU) 6041 and a microphone 6042. GPU 6041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on display unit 606. The image frames processed by GPU 6041 can be stored in memory 609 (or other storage medium) or transmitted via radio frequency unit 601 or network module 602. Microphone 6042 can receive sound and process such sound into audio data. The processed audio data can be converted into a format that can be transmitted to a mobile communication base station via radio frequency unit 601 in telephone call mode.

[0345] User equipment 600 also includes at least one sensor 605, such as a light sensor, a motion sensor, and other sensors.

The ambient light sensor can adjust the brightness of the display panel 6061 according to the ambient light level, and the proximity sensor can turn off the display panel 6061 and / or backlight when the user equipment 600 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used to identify the user equipment's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Sensor 605 may also include fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., which will not be described in detail here.

[0347] User input unit 607 can be used to receive input numerical or character information, and to generate key signal inputs related to user settings and function control of the user device. Specifically, user input unit 607 includes a touch panel 6071 and other input devices 6072. Touch panel 6071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 6071). Touch panel 6071 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to processor 610, which receives and executes commands from processor 610. In addition, touch panel 6071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. Besides touch panel 6071, user input unit 607 may also include other input devices 6072.

[0348] Furthermore, the touch panel 6071 can cover the display panel 6061. When the touch panel 6071 detects a touch operation on or near it, it transmits the information to the processor 610 to determine the type of touch event. Subsequently, the processor 610 provides corresponding visual output on the display panel 6061 based on the type of touch event. Although in Figure 6 In this embodiment, the touch panel 6071 and the display panel 6061 are two independent components to realize the input and output functions of the user device. However, in some embodiments, the touch panel 6071 and the display panel 6061 can be integrated to realize the input and output functions of the user device. The specific implementation is not limited here.

It is understood that the modem processor may not be integrated into processor 610.

[0352] User equipment 600 may also include a power supply 611 (such as a battery) that supplies power to various components. Preferably, the power supply 611 can be logically connected to the processor 610 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.
