Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, device and storage medium for determining resources. Background Technology

[0002] In communication systems, the resource selection mechanism of sidelinks (R16 or R17) operating in licensed frequency bands does not support the selection of continuous multi-slot resources; it only supports the selection of resources in a single time slot and does not support the selection of resources in multiple adjacent time slots. R18 requires further research into sidelink operation. In unlicensed frequency bands, LBT (Local Time-Based Transmission) is required, but the result of LBT is uncertain. If LBT fails, data cannot be transmitted on the selected resource. Therefore, to mitigate the impact of LBT failure, after a successful LBT, it is possible to support the transmission of a single time slot (TB) in multiple consecutive time slots, such as repeated transmission of one TB in multiple consecutive time slots, or transmission of multiple TBs in multiple consecutive time slots. This reduces the impact of LBT failure and improves the reliability of data transmission. Therefore, a "resource determination" method is urgently needed. During resource selection, it should support the selection of continuous multi-slot resources to determine resources with a time domain length of M consecutive time slots, thereby improving the convenience of resource determination and the reliability of data transmission.

[0099] Figure 1 This is an example illustration of a resource determination method provided in one embodiment of this disclosure. Figure 1 As shown, in unlicensed frequency bands, to mitigate the impact of Listen Before Talk (LBT) failures, transmission of a Transport Block (TB) in multiple consecutive time slots can be supported after a single successful LBT. Transmission of a TB in multiple consecutive time slots can be the continuous transmission of the same TB across multiple time slots. However, to support the transmission of a TB in multiple consecutive time slots, multiple consecutive resources need to be selected for the same TB, for example, M resources that are consecutive in the time domain.

[0100] The following is a detailed description of a method, apparatus, device, and storage medium for determining resources provided in the embodiments of this disclosure, with reference to the accompanying drawings.

[0101] Figure 2 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 2 As shown, the method may include the following steps:

[0102] Step 201: Based on the time slot parameter M, determine the first resource, wherein the time domain length of the first resource is M consecutive time slots, M is a positive integer and M>1, and the first resource is used for the transmission of the Physical Side Link Shared Channel (PSSCH) or the Physical Side Link Control Channel (PSCCH).

[0103] It should be noted that, in one embodiment of this disclosure, the terminal device can be a device that provides voice and / or data connectivity to a user. The terminal device can communicate with one or more core networks via a RAN (Radio Access Network). The terminal device can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent.

Alternatively, the terminal device can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0104] In one embodiment of this disclosure, R18 needs to study sidelink operation, which requires LBT (Local Bit Transmission) in unlicensed frequency bands. To mitigate the impact of LBT failure, after a successful LBT, the same TB or different TBs can be repeatedly transmitted in M ​​consecutive time slots for continuous transmission of PSSCH or PSCCH.

[0105] Based on the time slot parameter M, the first resource is determined, including:

[0106] Receive the time slot parameter M sent by the network-side device, where the time slot parameter M is used to indicate the number of consecutive time slots for PSSCH or PSCCH transmission;

[0107] Based on the time slot parameter M, a random resource is selected from the candidate resource set to determine the first resource. The time slot length of each candidate resource in the candidate resource set is M time slots.

[0108] Furthermore, in one embodiment of this disclosure, the first resource further includes L, which is continuous or discrete in the frequency domain. subCH If there are multiple subchannels, then the start and end positions of the frequency domain resources between adjacent time slots may be the same or different, where L subCH It is a positive integer.

[0109] Furthermore, in one embodiment of this disclosure, the first resource further includes X comb-scale resource block indices (IRB indices) that are continuous or discrete in the frequency domain, such that the start and end positions of the frequency domain resources between adjacent time slots are the same or different, where X is a positive integer.

[0110] Furthermore, in one embodiment of this disclosure, determining the first resource based on the time slot parameter M includes:

[0111] Based on the time slot parameter M, a first resource is determined from the candidate resource set, where the time domain length of each candidate resource in the candidate resource set is a single time slot. A single time slot can refer to one time slot.

[0112] Furthermore, in one embodiment of this disclosure, determining a first resource from the candidate resource set based on the time slot parameter M includes at least one of the following:

[0113] Based on the time slot parameter M, multiple resource selections are performed from the candidate resource set to determine the first resource, wherein the time slot length of each resource selection is a single time slot;

[0114] Based on the time slot parameter M, a resource selection is performed from the candidate resource set to determine the first resource, wherein the time slot length of the resource selection is M time slots.

[0115] For example, in one embodiment of this disclosure, performing multiple resource selections from a candidate resource set based on a time slot parameter M to determine a first resource includes:

[0116] Randomly select a first candidate resource x from the candidate resource set;

[0117] Based on the first candidate resource x, select M consecutive candidate resources corresponding to the time domain from the candidate resource set and use them as the first resource.

[0118] Furthermore, in one embodiment of this disclosure, the method further includes:

[0119] If a first resource cannot be selected from the candidate resource set based on the first candidate resource x, then a second candidate resource x is selected from the candidate resource set, and a first resource is selected again from the candidate resource set based on the second candidate resource x.

[0120] Furthermore, in one embodiment of this disclosure, selecting M consecutive time-domain corresponding candidate resources from the candidate resource set and using them as the first resource includes:

[0121] Select M consecutive time-domain candidate resources from the candidate resource set according to the first selection order, and use them as the first resource.

[0122] The first order can be in ascending order of time slots or in descending order of time slots; this disclosure does not limit this.

[0123] Furthermore, in one embodiment of this disclosure, the method further includes:

[0124] If no consecutive M time-domain candidate resources are selected in the candidate resource set according to the first selection order, then the consecutive N time-domain candidate resources selected in the first selection order are obtained and used as the second resource, where N is a positive integer less than M.

[0125] Based on the first candidate resource x, select MN consecutive time-domain corresponding candidate resources from the candidate resource set according to the second selection order, and use them as the third resource;

[0126] The second and third resources are combined into the first resource.

[0127] Furthermore, in one embodiment of this disclosure, the second selection order is in the opposite direction to the first selection order.

[0128] Furthermore, in one embodiment of this disclosure, a resource selection is performed from the candidate resource set based on the time slot parameter M to determine a first resource, including:

[0129] Multiple candidate resource subsets are identified, wherein the temporal resources of the candidate resource subsets are continuous, and the length of the temporal continuity is equal to or greater than M time slots;

[0130] For any subset of candidate resources, select M consecutive candidate resources corresponding to the time domain as the first resource.

[0131] For example, in one embodiment of this disclosure, the method further includes:

[0132] If the first resource does not exist in the candidate resource set, then the transmission of TB is stopped.

[0133] Furthermore, in one embodiment of this disclosure, the method further includes:

[0134] If the first resource does not exist in the candidate resource set, then the fourth resource is randomly selected from the candidate resource set, and the time domain length of the fourth resource is a single time slot;

[0135] Send one TB in a single timeslot.

[0136] Furthermore, in one embodiment of this disclosure, the method further includes:

[0137] If the first resource does not exist in the candidate set, then the fifth resource is selected from the candidate set. The time domain length of the fifth resource is L consecutive time slots, where L is a positive integer and is a positive integer less than M or a different TB.

[0138] Furthermore, in one embodiment of this disclosure, the method further includes:

[0139] The same TB or different TBs are repeatedly transmitted in M ​​consecutive time slots or L consecutive time slots.

[0140] In summary, in the embodiments of this disclosure, a first resource is determined based on the time slot parameter M, wherein the time domain length of the first resource is M consecutive time slots, M is a positive integer and M>1, and the first resource is used for the transmission of PSSCH or PSCCH. In the embodiments of this disclosure, the time slot parameter M allows selection of resources with a time domain length of M consecutive time slots, resolving the situation where continuous multi-time slot resource selection based on the R16 or R17 sidelink resource selection mechanism is not possible. This disclosure provides a processing method for a "resource determination" scenario, which supports the selection of continuous multi-time slot resources during resource selection to determine resources with a time domain length of M consecutive time slots, thereby improving the convenience of resource determination and the reliability of data transmission.

[0141] Figure 3 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 3 As shown, the method may include the following steps:

[0142] Step 301: Receive the time slot parameter M sent by the network-side device, wherein the time slot parameter M is used to indicate the number of consecutive time slots for PSSCH or PSCCH transmission;

[0143] Step 302: Based on the time slot parameter M, randomly select resources from the candidate resource set to determine the first resource, wherein the time slot length of each candidate resource in the candidate resource set is M time slots.

[0144] In one embodiment of this disclosure, the first resource further includes L, which is continuous or discrete in the frequency domain. subCH If there are multiple subchannels, then the start and end positions of the frequency domain resources between adjacent time slots may be the same or different, where L subCH It is a positive integer.

[0145] Furthermore, in one embodiment of this disclosure, a subchannel is a set of consecutive RBs (resource blocks) used for the transmission of PSCCH or PSSCH, and the transmission resources of the sidelink UE are allocated at the subchannel level.

[0146] For example, in one embodiment of this disclosure, the slot length of the candidate resource may be, for example, three slots. Figure 4 This is a schematic diagram illustrating an example of a resource start and end position provided in an embodiment of this disclosure. For example... Figure 4 As shown, the first resource also includes L, which is continuous or discrete in the frequency domain. subCH If there are multiple subchannels, then the start and end positions of the frequency domain resources between adjacent time slots are the same.

[0147] For example, in one embodiment of this disclosure, the slot length of the candidate resource may be, for example, three slots. Figure 5 This is a schematic diagram illustrating an example of a resource start and end position provided in an embodiment of this disclosure. For example... Figure 5 As shown, the first resource also includes L, which is continuous or discrete in the frequency domain. subCH If there are multiple subchannels, then the start and end positions of the frequency domain resources between adjacent time slots will be different. Each candidate resource can correspond to one subchannel.

[0148] For example, in one embodiment of this disclosure, the first resource further includes X interlaced resource block (IRB) indices that are continuous or discrete in the frequency domain. The start and end positions of the frequency domain resources between adjacent time slots may be the same or different, where X is a positive integer.

[0149] For example, in one embodiment of this disclosure, an Interlaced Resource Block (IRB) can be introduced in a 5G air interface (New Radio in Unlicensed Spectrum, NR-U) system operating in an unlicensed frequency band. This IRB consists of two consecutive available resource blocks spaced M resource blocks apart. For an IRB index m, the Physical Resource Blocks (PRBs) it includes can be, for example, {m, M+m, 2M+m, 3M+m, ...}, where m ∈ {0, 1, ..., M-1}. In the NR-U system, IRB structures are defined for 15kHz and 30kHz subcarrier spacings, as shown in Table 1.

[0150] Table 1

[0151] μ M 0 10 1 5

[0152] For example, in one embodiment of this disclosure, Figure 6 This is an example schematic diagram of an IRB provided as an embodiment of this disclosure. Figure 6 As shown, the sub-carrier space (SCS) can be, for example, 30kHz, i.e., SCS = 30kHz. When M = 5, there are a total of 5 comb ruler indices. For a comb ruler index, i.e., IRB index 0, the comb ruler index contains comb ruler resource blocks, for example, PRB{0,5,10,15,20,25,30,35,40,45}. Figure 7 This is an example schematic diagram of an IRB provided as an embodiment of this disclosure. Figure 7 As shown, SCS = 15kHz, M = 10.

[0153] For example, in one embodiment of this disclosure, the terminal device randomly selects a first resource from a set of candidate resources based on a timeslot parameter M. The time domain length of the first resource is M consecutive timeslots, and the terminal device can repeatedly transmit the same transmission block (TB) in the M consecutive timeslots. That is, the first resource can be used for repeated transmission of the same TB, or it can be used for continuous transmission of M TBs in M ​​timeslots.

[0154] For example, in one embodiment of this disclosure, when the terminal device obtains the time slot parameter M, the terminal device may also receive at least one of the following parameters to determine the first resource:

[0155] The resource pool to which the resource to be reported belongs;

[0156] Layer 1 (L1) priority;

[0157] Remaining packet delay budget;

[0158] The number of sub-channels or IRB indexes used for PSSCH or PSCCH transmission in a time slot;

[0159] Resource reservation interval.

[0160] For example, in one embodiment of this disclosure, when the terminal device receives the time slot parameter M, the resource pool to which the resource to be reported belongs, the L1 priority, the remaining data packet delay budget, the number of sub-channels or IRB indexes used for PSSCH or PSCCH transmission in a time slot, and the resource reservation interval, the terminal device can determine a set of candidate resources to determine the first resource.

[0161] For example, in one embodiment of this disclosure, the parameters received by the terminal device may include, for example, a time slot parameter M, the resource pool to which the resource to be reported belongs, a Layer 1 (L1) priority, the remaining data packet delay budget, the number of sub-channels or IRB indexes used for PSSCH or PSCCH transmission in a time slot, and the resource reservation interval. Based on these parameters, the terminal device can determine a candidate resource set and randomly select resources from the candidate resource set to determine a first resource. When determining the candidate resource set, the terminal device can, for example, determine the candidate resource set through sensing and resource exclusion, for example, by adopting the process of determining the candidate resource set using sidelink in 5G R16 or R17 international standards.

[0162] In summary, in the embodiments of this disclosure, a timeslot parameter M sent by a network-side device is received. The timeslot parameter M indicates the number of consecutive timeslots for PSSCH or PSCCH transmission. Based on the timeslot parameter M, a first resource is determined, where M is a positive integer and M > 1. The first resource is used for PSSCH or PSCCH transmission. In the embodiments of this disclosure, the timeslot parameter M allows selection of resources with a time domain length of M consecutive timeslots, resolving the situation where continuous multi-timeslot resource selection based on the R16 or R17 sidelink resource selection mechanism is not possible. This disclosure provides a processing method for a "resource determination" scenario, supporting the selection of continuous multi-timeslot resources during resource selection to determine resources with a time domain length of M consecutive timeslots, thereby improving the convenience of resource determination and the reliability of data transmission.

[0163] Figure 8 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 8 As shown, the method may include the following steps:

[0164] Step S801: Based on the time slot parameter M, determine the first resource from the candidate resource set, wherein the time domain length of each candidate resource in the candidate resource set is a single time slot.

[0165] In one embodiment of this disclosure, the terminal device may determine the candidate resource set using the process specified in R16 or R17. That is, the candidate resource set is a set of resources determined by the terminal device using the resource determination method in R16 or R17. This candidate resource set does not specifically refer to a fixed set. For example, when the number of candidate resources included in the candidate resource set changes, the candidate resource set may also change accordingly.

[0166] In summary, in the embodiments of this disclosure, a first resource is determined from a set of candidate resources based on a time slot parameter M, wherein the time domain length of each candidate resource in the set is a single time slot. In these embodiments, the time slot parameter M allows selection of resources with a time domain length of M consecutive time slots from a set of candidate resources where each candidate resource has a time domain length of a single time slot, thus resolving the situation where continuous multi-time slot resource selection based on the R16 or R17 sidelink resource selection mechanism is not possible. This disclosure provides a processing method for a "resource determination" scenario, supporting the selection of continuous multi-time slot resources during resource selection to determine resources with a time domain length of M consecutive time slots, thereby improving the convenience of resource determination and the reliability of data transmission.

[0167] Figure 9 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 9 As shown, the method may include the following steps:

[0168] Step 901: Based on the time slot parameter M, perform multiple resource selections from the candidate resource set to determine the first resource, wherein the time slot length of each resource selection is a single time slot.

[0169] In one embodiment of this disclosure, based on the time slot parameter M, the terminal device can perform multiple resource selections from the candidate resource set. Each time the resource is selected, the time slot length is a single time slot, and a continuous resource with a length of M time slots can be selected.

[0170] In summary, in the embodiments of this disclosure, multiple resource selections are performed from the candidate resource set based on the time slot parameter M to determine the first resource, wherein the time slot length of each selected resource is a single time slot. In the embodiments of this disclosure, since the time slot length of each selected resource in the candidate resource set is a single time slot, multiple resource selections can be performed based on the time slot parameter M to select resources with a time domain length of M consecutive time slots, reducing the possibility of not being able to select resources with consecutive multi-time slots. The embodiments of this disclosure specifically describe the characteristics of performing multiple resource selections to determine the first resource. This disclosure provides a processing method for a "resource determination" scenario, which can support the selection of consecutive multi-time slot resources during resource selection to determine resources with a time domain length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0171] Figure 10 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 10 As shown, the method may include the following steps:

[0172] Step 1001: Based on the time slot parameter M, perform a resource selection from the candidate resource set to determine the first resource, wherein the time slot length of the resource selection is M time slots.

[0173] In summary, in the embodiments of this disclosure, a resource selection is performed once from the candidate resource set based on the time slot parameter M to determine the first resource, wherein the time slot length of the resource selected in one step is M time slots. In the embodiments of this disclosure, resources with a time domain length of M consecutive time slots can be selected once from the candidate resource set, solving the problem of not being able to select consecutive multi-time slot resources based on the R16 or R17 sidelink resource selection mechanism. The embodiments of this disclosure specifically describe the characteristics of performing a single resource selection to determine the first resource. This disclosure provides a processing method for a "resource determination" scenario, which can support the selection of consecutive multi-time slot resources during resource selection to determine resources with a time domain length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0174] Figure 11 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 11 As shown, the method may include the following steps:

[0175] Step 1101: Randomly select a first candidate resource x from the candidate resource set;

[0176] Step 1102: Based on the first candidate resource x, select M consecutive candidate resources corresponding to the time domain from the candidate resource set and use them as the first resource.

[0177] In one embodiment of this disclosure, the time domain length of the first candidate resource x is one time slot, and the first candidate resource belongs to the resource in the candidate resource set.

[0178] For example, in one embodiment of this disclosure, when the terminal device selects a first candidate resource x, it can select M consecutive time-domain corresponding candidate resources from the candidate resource set based on the first candidate resource x, and use them as the first resource.

[0179] In summary, in the embodiments of this disclosure, a first candidate resource x is randomly selected from the candidate resource set. Based on the first candidate resource x, M consecutive time-domain corresponding candidate resources are selected from the candidate resource set and used as the first resource. In the embodiments of this disclosure, resources with a time-domain length of M consecutive time slots can be selected from the candidate resource set, solving the problem of not being able to select consecutive multi-time-slot resources based on the R16 or R17 sidelink resource selection mechanism. In the embodiments of this disclosure, it is specifically described that multiple resource selections are performed according to a first selection order to determine the characteristics of the first resource. This disclosure provides a processing method for a "resource determination" scenario, which can support the selection of consecutive multi-time-slot resources during resource selection to determine resources with a time-domain length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0180] Figure 12 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 12 As shown, the method may include the following steps:

[0181] Step 1201: Randomly select a first candidate resource x from the candidate resource set;

[0182] Step 1202: If the first resource cannot be selected from the candidate resource set based on the first candidate resource x, then the second candidate resource x is selected again from the candidate resource set, and the first resource is selected again from the candidate resource set based on the second candidate resource x.

[0183] In one embodiment of this disclosure, the time domain length of the first candidate resource x is one time slot, and the first candidate resource belongs to the resource in the candidate resource set.

[0184] For example, in one embodiment of this disclosure, when the terminal device selects a first candidate resource x, the terminal device can select M consecutive time-domain corresponding candidate resources from the candidate resource set based on the first candidate resource x. If the first resource cannot be selected from the candidate resource set based on the first candidate resource x, a second candidate resource x is reselected from the candidate resource set, and the first resource is selected again from the candidate resource set based on the second candidate resource x.

[0185] In one embodiment of this disclosure, the "second" in the second candidate resource x is only used to distinguish it from other candidate resources and does not specifically refer to a particular fixed candidate resource. The terminal device may, for example, select a first resource from the candidate resource set based on the first candidate resource x. If the terminal device does not select a first resource from the candidate resource set, the terminal device may, for example, reselect a second candidate resource x from the candidate resource set and then select a first resource again from the candidate resource set based on the second candidate resource x. For example, it could be that the second candidate resource x is reselected from a candidate resource set other than the first candidate resource x, and then the first resource is selected again from the candidate resource set based on the second candidate resource x.

[0186] For example, in one embodiment of this disclosure, if a first resource cannot be selected from the candidate resource set based on a second candidate resource x, a third candidate resource x is reselected from the candidate resource set, and a first resource is selected again from the candidate resource set based on the third candidate resource x.

[0187] In summary, in the embodiments of this disclosure, if a first resource cannot be selected from the candidate resource set based on the first candidate resource x, a second candidate resource x is reselected from the candidate resource set, and the first resource is selected again from the candidate resource set based on the second candidate resource x. In the embodiments of this disclosure, by using the time slot parameter M, resources with a time domain length of M consecutive time slots can be selected from the candidate resource set, solving the problem of not being able to select consecutive multi-time slot resources based on the R16 or R17 sidelink resource selection mechanism. In the embodiments of this disclosure, the feature that when multiple resource selections are performed according to the first selection order, and the first resource cannot be determined based on the first candidate resource x, the first resource can be determined based on the second candidate resource x is specifically described. This disclosure provides a processing method for a "resource determination" scenario, which can support the selection of consecutive multi-time slot resources during resource selection to determine resources with a time domain length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0188] Figure 13 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 13 As shown, the method may include the following steps:

[0189] Step 1301: Select M consecutive time-domain corresponding candidate resources from the candidate resource set according to the first selection order, and use them as the first resource.

[0190] In one embodiment of this disclosure, the first selection order does not specifically refer to a fixed selection order. The "first" in the first selection order is only used to distinguish it from other selection orders. For example, the terminal device may select M consecutive time-domain corresponding candidate resources from the candidate resource set according to the first selection order based on the first candidate resource x, and use them as the first resource.

[0191] For example, in one embodiment of this disclosure, the time domain corresponding to the first candidate resource x may be, for example, 'a'. The first selection order may be, for example, the selection order from time domain a-1 to time domain a-M+1. The selection order from time domain a-1 to time domain a-M+1 may refer to the selection order from time slot a-1 to time slot a-M+1, or the selection order from time a-1 to time a-M+1.

[0192] For example, in one embodiment of this disclosure, the first selection order can be, for example, the selection order from time domain a-1 to time domain a-M+1. The terminal device can select a candidate resource from time domains a-1 to a-M+1 respectively according to the first selection order to determine the first resource. For example, the terminal device can first select a candidate resource in time domain a-1. If the terminal device selects a resource in time domain a-1, it can continue to select a resource in time domain a-2 according to the first selection order. If the terminal device selects a resource in time domain a-2, it can continue to select a resource in time domain a-3 according to the first selection order. If a resource is selected from time domains a-1 to a-M+1 according to the first selection order, all selected resources can form the first resource, that is, a first resource with a time domain length of M consecutive time slots.

[0193] For example, in one embodiment of this disclosure, if a first resource cannot be selected from the candidate resource set based on a first candidate resource x, a second candidate resource x is reselected from the candidate resource set, and a first resource is selected again from the candidate resource set based on the second candidate resource x. The terminal device may select M consecutive time-domain corresponding candidate resources from the candidate resource set according to a first selection order based on the second candidate resource x, and use them as the first resource.

[0194] For example, in one embodiment of this disclosure, the time domain corresponding to the second candidate resource x can be, for example, c. The terminal device selects M consecutive candidate resources corresponding to time domains from the candidate resource set according to a first selection order from time domain c-1 to time domain c-M+1, and uses them as the first resource. For example, the terminal device can first select a candidate resource in time domain c-1. If the terminal device selects a resource in time domain c-1, the terminal device can continue to select a resource in time domain c-2 according to the first selection order. If the terminal device selects a resource in time domain c-2, the terminal device can continue to select a resource in time domain c-3 according to the first selection order. If a resource is selected from time domain c-1 to time domain c-M+1 according to the first selection order, then all the selected resources can form the first resource, that is, they can form a first resource with a time domain length of M consecutive time slots.

[0195] In summary, in the embodiments of this disclosure, M consecutive time-domain candidate resources are selected from the candidate resource set according to a first selection order and used as the first resource. In the embodiments of this disclosure, resources with a time-domain length of M consecutive time slots can be selected from the candidate resource set, solving the problem of not being able to select consecutive multi-time-slot resources based on the R16 or R17 sidelink resource selection mechanism. In the embodiments of this disclosure, it is specifically described that multiple resource selections are performed according to the first selection order to determine the characteristics of the first resource. This disclosure provides a processing method for a "resource determination" scenario, which can support the selection of consecutive multi-time-slot resources during resource selection to determine resources with a time-domain length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0196] Figure 14 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 14 As shown, the method may include the following steps:

[0197] Step 1401: If M consecutive time-domain corresponding candidate resources cannot be selected in the candidate resource set according to the first selection order, then obtain N consecutive time-domain corresponding candidate resources selected according to the first selection order and use them as the second resource, where N is a positive integer less than M.

[0198] Step 1402: Based on the first candidate resource x, select MN consecutive time-domain corresponding candidate resources from the candidate resource set according to the second selection order, and use them as the third resource.

[0199] Step 1403: Combine the second and third resources as the first resource.

[0200] For example, in one embodiment of this disclosure, the first selection order does not specifically refer to a fixed order. The "first" in the first selection order is only used to distinguish it from the second selection order. The second selection order does not specifically refer to a fixed selection order. The "second" in the second selection order is only used to distinguish it from other selection orders. The second selection order is in the opposite direction to the first selection order.

[0201] In one embodiment of this disclosure... Figure 15 This is an example schematic diagram illustrating a resource determination method provided in an embodiment of this disclosure. For example... Figure 15 As shown, the terminal device may, for example, acquire N consecutive candidate resources corresponding to time domains selected in a first selection order as second resources, select MN consecutive candidate resources corresponding to time domains from the candidate resource set in a second selection order as third resources, and merge the second resources and the third resources as the first resource.

[0202] For example, in one embodiment of this disclosure, the time domain corresponding to the first candidate resource x can be, for example, 'a'. The first selection order can be, for example, the selection order of time domains a-1 to a-M+1. The terminal device can, for example, select candidate resources corresponding to M consecutive time domains according to the first selection order of time domains a-1 to a-M+1, for example, it can select one resource from time domains a-1 to a-M+1 respectively. If there is a candidate resource in any time domain aN-1 that is not selected, the terminal device can obtain the candidate resources corresponding to N consecutive time domains selected according to the first selection order and use them as the second resource, and not select candidate resources between time domains aN-1 and a-M+1. Wherein, the time domain length of the second resource is N consecutive time slots, that is, the terminal device can determine N time slots.

[0203] For example, in one embodiment of this disclosure, the terminal device can obtain the difference between M and N, that is, the terminal device can determine MN consecutive time domains, where MN time domains can be, for example, R time domains. The terminal device can, for example, select one resource from the candidate resource set from time domain a+1 to a+M+1 in a second selection order from time domain a+1 to time domain a+M-1, and the terminal device can determine R consecutive time slots as the third resource. The terminal device can combine the second and third resources as the first resource, that is, the terminal device can combine N consecutive time slots and R consecutive time slots into M consecutive time slots.

[0204] For example, in one embodiment of this disclosure, the terminal device merges the second resource and the third resource as the first resource, and the terminal device no longer performs resource selection.

[0205] For example, in one embodiment of this disclosure, the terminal device may select resources according to a second selection order from time domain a+1 to time domain a+M-1. For instance, in a set of candidate resources, the terminal device may select one resource from time domain a+1 to time domain a+M+1 respectively. According to the second selection order from time domain a+1 to time domain a+M-1, if any candidate resource in time domain a+B is not selected, the terminal device will not select any candidate resource from time domain aB to time domain a+M+1.

[0206] For example, in one embodiment of this disclosure, the terminal device can randomly select a second candidate resource x from the candidate resource set other than the first candidate resource x, wherein the second candidate resource x is different from the first candidate resource x. The terminal device can, for example, select M consecutive time-domain corresponding candidate resources from the candidate resource set according to a first selection order based on the second candidate resource x, and use them as the first resource. If, based on the second candidate resource x, it fails to select M consecutive time-domain corresponding candidate resources from the candidate resource set according to the first selection order, then it obtains N consecutive time-domain corresponding candidate resources selected according to the first selection order and uses them as the second resource, where N is a positive integer less than M; again, based on the second candidate resource x, it selects MN consecutive time-domain corresponding candidate resources from the candidate resource set according to a second selection order and uses them as the third resource. The terminal device can combine the second resource and the third resource as the first resource.

[0207] For example, in one embodiment of this disclosure, the time domain corresponding to the second candidate resource x can be, for example, c. The terminal device selects M consecutive candidate resources corresponding to time domains from the candidate resource set according to a first selection order from time domain c-1 to time domain c-M+1, and uses them as the first resource. For example, the terminal device can first select a candidate resource in time domain c-1. If the terminal device selects a resource in time domain c-1, the terminal device can continue to select a resource in time domain c-2 according to the first selection order. If the terminal device selects a resource in time domain c-2, the terminal device can continue to select a resource in time domain c-3 according to the first selection order. If a resource is selected from time domain c-1 to time domain c-M+1 according to the first selection order, then all the selected resources can form the first resource, that is, they can form a first resource with a time domain length of M consecutive time slots. If any candidate resource in time domain cN-1 is not selected, the terminal device can acquire N consecutive candidate resources corresponding to time domains selected in the first selection order, and use them as the second resource, without selecting candidate resources between time domains cN-1 and c-M+1. The time domain length of the second resource is N consecutive time slots.

[0208] For example, in one embodiment of this disclosure, the terminal device can obtain the difference between M and N, that is, the terminal device can determine MN consecutive time domains. For instance, the terminal device can select one resource from the candidate resource set from time domain c+1 to c+M+1 in a second selection order from time domain c+1 to time domain c+M-1, thereby determining MN time slots as the third resource. The terminal device can combine the second and third resources as the first resource, that is, the terminal device can combine N consecutive time slots and MN consecutive time slots into M consecutive time slots.

[0209] In summary, in the embodiments of this disclosure, if M consecutive time-domain corresponding candidate resources cannot be selected from the candidate resource set according to the first selection order, then N consecutive time-domain corresponding candidate resources selected according to the first selection order are obtained and used as the second resource, where N is a positive integer less than M. Based on the first candidate resource x, MN consecutive time-domain corresponding candidate resources are selected from the candidate resource set according to the second selection order and used as the third resource. The second and third resources are then merged as the first resource. In the embodiments of this disclosure, the time slot parameter M allows the selection of a first resource with a time-domain length of M consecutive time slots from the candidate resource set, resolving the situation where continuous multi-time-slot resource selection based on the R16 or R17 sidelink resource selection mechanism is not possible. In the embodiments of this disclosure, multiple resource selections are specifically performed according to the first and second selection orders to determine the characteristics of the first resource. This disclosure provides a processing method for a "resource determination" scenario, which supports the selection of continuous multi-time-slot resources during resource selection to determine resources with a time-domain length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0210] Figure 16 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 16 As shown, the method may include the following steps:

[0211] Step 1601: Determine multiple candidate resource subsets, wherein the temporal domain resources of the candidate resource subsets are continuous, and the length of the temporal continuation is equal to or greater than M time slots;

[0212] Step 1602: Select any subset of candidate resources, and select M consecutive candidate resources corresponding to the time domain as the first resource.

[0213] In one embodiment of this disclosure... Figure 17 This is a flowchart illustrating a method for determining a subset of candidate resources provided in an embodiment of this disclosure. Figure 17As shown, the temporal resources of the candidate resource subset can be, for example, continuous, and the length of the temporal continuity is equal to or greater than 3 time slots. The terminal device can identify at least one candidate resource in the candidate resource set and select multiple candidate subsets with a temporal continuity length equal to or greater than 3 time slots. The time slot parameter M can be, for example, 3. Based on the time slot parameter M, candidate resources corresponding to 3 consecutive time domains can be selected from the candidate resource subset as the first resource. If the candidate resource subset has multiple candidate resources corresponding to M consecutive time domains, the terminal device can randomly select one candidate resource from the multiple candidate resources corresponding to M consecutive time domains as the first resource.

[0214] In summary, in the embodiments of this disclosure, multiple candidate resource subsets are determined, wherein the temporal resources of the candidate resource subsets are continuous, and the temporal continuity length is equal to or greater than M time slots. Random resource selection is performed on any candidate resource subset, selecting the M consecutive time-domain corresponding candidate resources as the determined first resource. In the embodiments of this disclosure, the time slot parameter M allows selection of resources with a temporal length of M consecutive time slots from the candidate resource set, solving the problem of not being able to select consecutive multi-time-slot resources based on the R16 or R17 sidelink resource selection mechanism. In the embodiments of this disclosure, the characteristics of performing a single resource selection to determine the first resource are specifically described. By identifying at least one candidate resource in the candidate resource set, the accuracy of obtaining candidate resource subsets can be improved, thus improving the accuracy of determining the first resource. This disclosure provides a processing method for a "resource determination" scenario, which supports the selection of consecutive multi-time-slot resources during resource selection to determine resources with a temporal length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0215] Figure 18 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 18 As shown, the method may include the following steps:

[0216] Step 1801: According to the selection order of the temporally continuous length of at least one candidate resource in the candidate resource subset from longest to shortest, determine the first resource that is temporally continuous and has a length of M time slots, wherein the temporal length of the first resource is M time slots.

[0217] In one embodiment of this disclosure, according to the selection order of the temporally continuous length of at least one candidate resource in the candidate resource subset from longest to shortest, the terminal device may select the first temporally continuous candidate resource with a length of M time slots as the first resource.

[0218] In summary, in the embodiments of this disclosure, a first resource with a temporal continuity and a length of M time slots is determined according to the selection order of the temporal continuity of at least one candidate resource in the candidate resource subset from longest to shortest. The temporal length of the first resource is M time slots. In the embodiments of this disclosure, the time slot parameter M allows selection of resources with a temporal length of M consecutive time slots from the candidate resource set, resolving the situation where continuous multi-time slot resource selection based on the R16 or R17 sidelink resource selection mechanism is not possible. Specifically, the embodiments of this disclosure describe the characteristics of performing a resource selection to determine the first resource. By identifying at least one candidate resource in the candidate resource set, the accuracy of candidate resource subset acquisition can be improved. Determining the first resource according to the selection order of the temporal continuity of at least one candidate resource from longest to shortest improves the accuracy of first resource determination. This disclosure provides a processing method for a "resource determination" scenario, which supports the selection of continuous multi-time slot resources during resource selection to determine resources with a temporal length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0219] Figure 19 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 19 As shown, the method may include the following steps:

[0220] Step 1901: Determine the first resource according to the selection order of the temporal domain continuity length of at least one candidate resource in the candidate resource subset from shortest to longest, wherein the temporal domain length of the first resource is M time slots.

[0221] In one embodiment of this disclosure, according to the selection order of the temporally continuous length of at least one candidate resource in the candidate resource subset from shortest to longest, the terminal device may select the first temporally continuous candidate resource with a length of M time slots as the first resource.

[0222] In summary, in the embodiments of this disclosure, a first resource is determined according to the selection order of the temporal domain contiguous length of at least one candidate resource in the candidate resource subset, from shortest to longest. The temporal domain length of the first resource is M time slots. In this embodiment, the time slot parameter M allows for the selection of resources with M consecutive time slots in the temporal domain from the candidate resource set, resolving the situation where continuous multi-time slot resource selection based on the R16 or R17 sidelink resource selection mechanism is not possible. Specifically, this disclosure describes the characteristics of performing a resource selection to determine the first resource. By identifying at least one candidate resource in the candidate resource set, the accuracy of candidate resource subset acquisition can be improved. Determining the first resource according to the selection order of the temporal domain contiguous length of at least one candidate resource from shortest to longest can improve the accuracy of the first resource determination. This disclosure provides a processing method for a "resource determination" scenario, which supports the selection of continuous multi-time slot resources during resource selection to determine resources with a temporal domain length of M consecutive time slots, improving the convenience of resource determination and the reliability of data transmission.

[0223] Figure 20 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 20 As shown, the method may include the following steps:

[0224] Step 2001: If the first resource does not exist in the candidate resource set, then stop the transmission of TB.

[0225] In one embodiment of this disclosure, the terminal device can select a first resource from a set of candidate resources based on time slot parameters. If the first resource does not exist in the set of candidate resources, the terminal device can stop the transmission of TB.

[0226] In summary, in the embodiments of this disclosure, if the first resource does not exist in the candidate resource set, the transmission of the TB is stopped. In the embodiments of this disclosure, by determining that the first resource does not exist in the candidate resource set, the transmission of the TB can be stopped, reducing resource consumption caused by transmitting the same TB. This disclosure provides a processing method for a "resource determination" scenario, which can stop the transmission of the TB when the first resource does not exist in the candidate resource set, thereby reducing resource consumption.

[0227] Figure 21 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 21 As shown, the method may include the following steps:

[0228] Step 2101: If the first resource does not exist in the candidate resource set, then a fourth resource is randomly selected from the candidate resource set. The time domain length of the fourth resource is a single time slot.

[0229] Step 2102: Send a TB in a single time slot.

[0230] In one embodiment of this disclosure, the terminal device can select a first resource from a set of candidate resources based on time slot parameters. If the first resource does not exist in the set of candidate resources, a fourth resource is randomly selected from the set. Since the time domain length of the fourth resource is a single time slot, the terminal device can randomly select a single time slot from the set of candidate resources and transmit one TB in that single time slot. When the terminal device randomly selects the fourth resource from the set of candidate resources, it can execute the R16 procedure, that is, randomly select the fourth resource in a single time slot. In other words, the terminal device does not perform transmission of M consecutive time slots.

[0231] Furthermore, in one embodiment of this disclosure, the fourth resource does not specifically refer to a fixed resource. For example, the fourth resource may also change accordingly when a single time slot changes.

[0232] In summary, in the embodiments of this disclosure, if the first resource does not exist in the candidate resource set, a fourth resource is randomly selected from the candidate resource set. The time domain length of the fourth resource is a single time slot, and one TB can be transmitted in a single time slot. In the embodiments of this disclosure, by determining that if the first resource does not exist in the candidate resource set and it is impossible to transmit the same TB using M consecutive time slots, one TB can be transmitted in a single time slot, reducing the possibility of the same TB being unable to be transmitted. This disclosure provides a processing method for a "resource determination" scenario, which allows one TB to be transmitted in a single time slot.

[0233] Figure 22 This is a flowchart illustrating a resource determination method provided in an embodiment of the present disclosure. The method is executed by a terminal device, such as... Figure 22 As shown, the method may include the following steps:

[0234] Step 2201: If the first resource does not exist in the candidate set, then select the fifth resource from the candidate set, wherein the time domain length of the fifth resource is L consecutive time slots, where L is a positive integer and L is a positive integer less than M.

[0235] Step 2202: Repeat the transmission of the same TB or different TBs in L consecutive time slots.

[0236] Furthermore, in one embodiment of this disclosure, the fifth resource does not specifically refer to a fixed resource. For example, when the value of L changes in the L time slots, the fifth resource may also change accordingly.

In the embodiments of this disclosure, by determining that if the first resource does not exist in the candidate resource set and it is impossible to transmit the same TB using M consecutive time slots, the same TB or different TBs can be repeatedly transmitted within L consecutive time slots, reducing the possibility of the same TB or different TBs being unable to be transmitted. This disclosure provides a processing method for a "resource determination" scenario, allowing the same TB or different TBs to be repeatedly transmitted within L consecutive time slots.
