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 selecting resources across multiple time slots. Background Technology

[0002] In communication systems, under unlicensed frequency bands (i.e., shared frequency bands), listen-before-talk (LBT) is required. However, the result of LBT is uncertain. If LBT fails, data cannot be transmitted on the selected resources. Therefore, to mitigate the impact of LBT failure, after a successful LBT, transport blocks (TBs) can be transmitted in consecutive time slots. This can be achieved by repeatedly transmitting multiple identical TBs in consecutive time slots, or by transmitting multiple different TBs in consecutive time slots. This reduces the impact of LBT failure and improves channel access efficiency. However, when multiple TBs arrive simultaneously, how the terminal device can sequentially select resources for multiple TBs and choose resources with consecutive time slots becomes a critical problem to solve. Summary of the Invention

[0003] This disclosure presents a continuous multi-timeslot resource selection method, apparatus, device, and storage medium. When the physical layer of a terminal device simultaneously reaches m TBs, resources can be selected sequentially for each of the m TBs according to a determined resource selection order. This can determine m resources that are continuous in the time domain, thereby achieving continuous multi-timeslot resource selection, reducing the impact of LBT failures, and improving channel access efficiency.

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this disclosure as detailed in the appended claims.

[0038] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0039] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0040] The network elements or network functions involved in the embodiments of this disclosure can be implemented by independent hardware devices or by software in hardware devices. This disclosure does not limit this.

[0041] Figure 1 This is a schematic diagram illustrating an example of a continuous multi-timeslot resource selection 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 blocks (TBs) can be supported in multiple consecutive time slots after a single successful LBT. For example, Figure 1 This illustrates transmission over three consecutive time slots following a successful LBT. Of course, this is just an example; transmission can occur over more or fewer consecutive time slots.

[0042] It should be understood that the transmission of multiple consecutive time slots can support the transmission of multiple consecutive transport blocks (TBs) across multiple consecutive time slots. The consecutive transmission of multiple TBs can be multiple different TBs from the same user equipment (UE), repeated transmission of multiple identical TBs from the same UE, or simultaneous transmission of multiple TBs of the same TB and different TBs. To achieve consecutive multi-time-slot transmission, it is necessary to select consecutive multi-time-slot resources. However, currently, the selection of consecutive resources is not supported. That is, resource selection among multiple TBs is independent of each other, and it cannot be guaranteed that the resources selected by multiple TBs are consecutive. Therefore, when multiple TBs arrive simultaneously, the higher layer cannot ensure that resource selection from the candidate resource set corresponding to the TBs is time-domain consecutive. Furthermore, typically, for TBs arriving sequentially, the higher layer performs resource selection for the TBs in the order of arrival. However, when multiple TBs arrive simultaneously, the higher layer cannot determine the order in which the resource selection is performed for the multiple TBs because these TBs do not arrive in sequence.

[0043] The following describes in detail, with reference to the accompanying drawings, a method, apparatus, device, and storage medium for selecting resources across multiple time slots according to embodiments of the present disclosure.

[0044] Figure 2 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 2 As shown, the method may include the following steps:

[0045] Step 201: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0046] Step 202: Determine the order of resource selection for m transport blocks (TB);

[0047] Step 203: Select resources for each of the m TBs in the determined order.

[0048] 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 device from an unmanned aerial vehicle (UAV). Alternatively, the terminal device can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. 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.

[0049] In one embodiment of this disclosure, transmission across multiple consecutive time slots can be supported in unlicensed frequency bands, meaning that transmission of multiple consecutive TBs in multiple consecutive time slots is supported. The technical solution of this disclosure can be applied to sidelink communication on shared frequency bands. Multiple TBs refer to those automatically generated by the terminal device based on services; that is, when a service is generated in the terminal device, a TB can be automatically generated. For example, if the terminal device has several services, its physical layer can cache several TBs.

[0050] For example, in one embodiment of this disclosure, m transport blocks TB are m consecutive resources in the time domain.

[0051] Furthermore, in one embodiment of this disclosure, if the m TBs are generated at the same time, arrive at the physical layer of the terminal device simultaneously, and there is no order among the m TBs, then the physical layer of the terminal device will be triggered to select resources simultaneously by the m TBs. For the m TBs, the physical layer of the terminal device generates a total of N candidate resource sets, where N does not exceed m. For example, the physical layer of the terminal device can simultaneously report N candidate resource sets SA to the higher layers of the terminal device. The N candidate resource sets SA can be, for example, {SA1, SA2, ..., SAN}, 1 ≤ N ≤ m. Wherein, when N = 1, the m TBs are the same TB, or when N = m, the m TBs are different TBs. The higher layers of the terminal device select temporally contiguous resources from the simultaneously arriving m TBs and perform continuous multi-timeslot transmission.

[0052] In one embodiment of this disclosure, determining the resource selection order of m transport blocks TB includes:

[0053] When selecting resources for any one of the m TBs, in the candidate resource set of any one TB, resources that are located in adjacent time slots to one or more TBs in the higher layers of the terminal device that have been selected but not used for actual transmission are preferentially selected.

[0054] For example, in one embodiment of this disclosure, the terminal device can determine an order for m Transport Blocks (TBs), which is the order in which resources are selected for the m Transport Blocks (TBs). The terminal device can sequentially select resources for initial transmission and retransmission for each TB according to this order. When selecting resources for any TB, the terminal device can preferentially select resources in the candidate resource set corresponding to that TB that are located in adjacent time slots to resources already selected but not used for actual transmission in one or more TBs in the terminal device's higher layers.

[0055] Furthermore, in one embodiment of this disclosure, if m resources that are temporally consecutive are selected for m TBs, then m TBs are continuously transmitted on the selected temporally consecutive m resources.

[0056] If k temporally consecutive resources are selected from m TBs, where 1 < k < m and k is a positive integer, then the corresponding k TBs are sent consecutively on the selected k resources.

[0057] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0058] For example, in one embodiment of this disclosure, determining the order of resource selection for m transport blocks TB includes:

[0059] The order of resource selection is determined based on the number of resources in each TB's candidate resource set that are located in adjacent time slots to resources already selected by the higher layers of the terminal device but not used for actual transmission. In each instance, resources are selected from the TB corresponding to the candidate resource set with the largest number of resources located in adjacent time slots to resources already selected by the higher layers of the terminal device but not used for actual transmission.

[0060] Furthermore, in one embodiment of this disclosure, when selecting resources for any TB, if there are multiple TB candidate resource sets containing the same number of resources in adjacent time slots as the resources selected by the higher layers of the terminal device but not used for actual transmission, one TB can be randomly selected from the multiple TBs to select resources for any TB.

[0061] For example, in one embodiment of this disclosure, the terminal device randomly selects any one of m TBs and performs random resource selection in the candidate resource set corresponding to the any one TB. Resources that can be selected for initial transmission and retransmission are selected. Then, the terminal device has resources that have been selected but not used for actual transmission.

[0062] For example, in one embodiment of this disclosure, j resources are randomly selected for TB1, {r1, r2, r3, r4, ..., rj}, where j ≤ the maximum number of initial and retransmissions for one TB as indicated by the higher layer of the terminal device.

[0063] For example, in one embodiment of this disclosure, the terminal device can, one by one, determine the candidate resource set corresponding to the remaining TBs for which resource selection has not been performed, and determine the TB corresponding to the candidate resource set with the largest number of resources that are located in adjacent time slots as one or more TBs in the higher layers of the terminal device that have been selected but not used for actual transmission. The terminal device can select resources for any TB, prioritizing the selection of resources that are located in adjacent time slots as the resources that have been selected but not used for actual transmission in the higher layers of the terminal device. The resources selected for any TB and the existing resources in the higher layers of the terminal device are all called resources that have been selected but not used for actual transmission. The terminal device can then determine again which TB's candidate resource set contains the TB corresponding to the candidate resource set with the largest number of resources that are located in adjacent time slots as the resources that have been selected but not used for actual transmission in the higher layers of the terminal device. If so, it can select resources for any TB. This process is repeated until resource selection has been performed on each of the m TBs in the higher layers of the terminal device.

[0064] For example, in one embodiment of this disclosure, when 4 TBs arrive simultaneously, the physical layer of the terminal device can simultaneously report 4 candidate resource sets to the higher layers of the terminal device. These 4 candidate resource sets can be, for example, SA1, SA2, SA3, and SA4, where m=4. The higher layers of the terminal device need to select resources that are consecutive in the time domain for 4 time slots. Assume that 5 resources are selected from each candidate resource set for initial transmission and retransmission. The higher layers of the terminal device randomly select a candidate resource set SA1 corresponding to one TB from the 4 candidate resource sets, such as TB1, and select 5 resources {r1, r2, r3, r4, r5} from this candidate resource set. The higher layers of the terminal device then evaluate each of the remaining 3 TBs corresponding to candidate resource sets SA2, SA3, and SA4, and find that candidate resource set SA3 contains the 3 most numerous resources that are located in adjacent time slots to the already selected resources. Therefore, resources {y1, y2, y3, y4, y5} are selected from SA3, where y1 and r1 form a... Adjacent time-slot resources: y2 and r2 form adjacent time-slot resources, y3 and r4 form adjacent time-slot resources, and y4 and y5 are not located in adjacent time slots with resources existing in the higher layers of the terminal device. Therefore, the resources currently selected but not used for data transmission in the higher layers of the terminal device are {r1y1, r2y2, r3, r4y3, r5, y4, y5}. The higher layers of the terminal device select resources from the remaining 2 TB corresponding to the candidate resource sets SA2 and SA4. It is found that the two resources with the largest number in candidate resource set SA2 are located in adjacent time slots with the selected resources. If resource y1 and x2 are in adjacent time slots, and resource y3 and x3, and resources x4 and x5 are not in adjacent time slots with resources in the higher layers of the terminal device, then resources {x1, x2, x3, x4, x5} are selected. Finally, resources {z1, z2, z3, z4, z5} are selected for TB4 in SA4. Z1 is in adjacent time slots with resource x1, and Z3 is in adjacent time slots with resource x2. Therefore, the higher layers of the terminal device have performed resource selection for all four TBs. The resources that have been selected but not used for actual transmission in the higher layers of the terminal device are {r1y1x1z1, r2y2, r3, z2, z4, r4y3x2z3, r5, x3, x4, x5, z5, y4, y5}. Therefore, the higher layers of the terminal device have selected two sets of resources with four consecutive time slots in the time domain: {r1y1x1z1, r4y3x2z3}.

[0065] Furthermore, in one embodiment of this disclosure, determining the order of resource selection for m transport blocks TB includes:

[0066] The order of resource selection is determined according to the priority of each TB.

[0067] Furthermore, in one embodiment of this disclosure, the priority of each TB may be preset.

[0068] For example, in one embodiment of this disclosure, if the priorities of the m TBs are different, resource selection can be performed on the m TBs in descending or ascending order of their priorities.

[0069] Furthermore, in one embodiment of this disclosure, according to the priority of m TBs from high to low, the terminal device first performs random resource selection for the TB with the highest priority in its corresponding candidate resource set, and then performs resource selection for the remaining TBs in their corresponding candidate resource sets in order of priority from high to low. When selecting resources for each TB, resources located in adjacent time slots are selected from one or more resources in the higher layers of the terminal device that have been selected but not used for actual transmission. The resources selected by each TB are all resources that have been selected but not used for actual transmission.

[0070] Furthermore, in one embodiment of this disclosure, determining the order of resource selection for m transport blocks TB includes:

[0071] The order of resource selection is determined based on the Packet Delay Budget (PDB) value per TB.

[0072] In one embodiment of this disclosure, the higher layers of the terminal device are aware of the priority of each TB and the PDB value of each TB.

[0073] For example, in one embodiment of this disclosure, if the PDB values ​​of m TBs are all different, resource selection can be performed on the m TBs in ascending or descending order of PDB values. For instance, when performing resource selection in ascending order of PDB values, resource selection can be prioritized for TBs with smaller PDB values, i.e., those with higher latency requirements.

[0074] Furthermore, in one embodiment of this disclosure, the terminal device can first perform random resource selection for the TB with the smallest PDB value in its corresponding candidate resource set, in order of increasing PDB value, and then perform resource selection for the remaining TBs in their corresponding candidate resource sets in sequence. When selecting resources for each TB, resources located in adjacent time slots are selected from one or more resources in the higher layers of the terminal device that have been selected but not used for actual transmission. The resources selected for each TB are all resources that have been selected but not used for actual transmission.

[0075] Furthermore, in one embodiment of this disclosure, where each TB corresponds to a different destination terminal device, determining the resource selection order of m transport blocks TB includes:

[0076] The order of resource selection is determined by the Layer 1 destination identifier ID value for each TB.

[0077] For example, in one embodiment of this disclosure, if the destination terminal devices of m TBs are different, resource selection is performed on the m TBs in ascending or descending order of their corresponding 16-bit Layer 1 destination ID values.

[0078] Furthermore, in one embodiment of this disclosure, the terminal device first performs random resource selection for the TB with the smallest destination ID value in its corresponding candidate resource set, in ascending order of Layer 1 destination ID values. Then, it sequentially performs resource selection for the remaining TBs in their corresponding candidate resource sets. When selecting resources for each TB, it selects resources located in adjacent time slots to resources already selected by one or more TBs in the higher layers of the terminal device that have not been used for actual transmission. Specifically, the resources selected by each TB are resources that have already been selected but not used for actual transmission.

[0079] For example, in one embodiment of this disclosure, determining the order of resource selection for m transport blocks TB includes:

[0080] The order of resource selection is determined by the time when the higher-level layer of the terminal device receives the candidate resource set for each TB.

[0081] Furthermore, in one embodiment of this disclosure, m resource blocks (TBs) arrive simultaneously without any order. The physical layer is triggered to select resources by the m TBs in slot n simultaneously. For the m TBs, the physical layer generates N candidate resource sets. However, the physical layer of the terminal device reports N candidate resource sets SA to the higher layer of the terminal device at different times, such as {SA1, SA2, ..., SAN}. The terminal device can determine the order of resource selection according to the time order in which the higher layer of the terminal device receives the candidate resource sets of each TB. That is, the higher layer of the terminal device first performs selection for the TB corresponding to the first received candidate resource set.

[0082] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer may refer to the Medium Access Control Sublayer (MAC) layer.

[0083] For example, in one embodiment of this disclosure, the resource selection method can be applied to the following scenarios:

[0084] Scenario 1: If m TBs are different TBs, then the physical layer of the terminal device generates and reports m candidate resource sets {SA1, SA2, ..., SAm-1} to the higher layers of the terminal device.

[0085] Using the above method, the higher layers of the terminal device select continuous time slot resources for initial transmission or retransmission in the corresponding candidate resource set for each TB.

[0086] Scenario 2: If m TBs are the same TB, then the physical layer only generates and reports one candidate resource set {SA1} to the higher layer of the terminal device;

[0087] Using the above method, the higher layers of the terminal device select continuous time slot resources for initial transmission or retransmission in SA1 for each TB.

[0088] Scenario 3: If m TBs are composed of a identical TBs and b different TBs, then the physical layer of the terminal device generates and reports (1+b) candidate resource sets {SA1, SA2, ..., SAb+1} to the higher layer of the terminal device.

[0089] a) If two identical TBs select resources from the same candidate resource set, such as SA1, b) If two different TBs select resources from their respective candidate resource sets, the higher layers of the terminal device select continuous time slot resources for each TB for initial transmission or retransmission.

[0090] In summary, in the embodiments of this disclosure, m transport blocks (TBs) arriving simultaneously at the physical layer of the terminal device are determined, where m is a positive integer greater than 1; the resource selection order of the m transport blocks (TBs) is determined, and resources are selected for each TB in the m TBs sequentially according to the order. This disclosure provides a continuous multi-timeslot resource selection mechanism, reducing the situation where multiple TBs cannot be selected sequentially in the time domain when they arrive simultaneously, thus improving the convenience of continuous multi-timeslot resource selection. This disclosure provides a processing method for the scenario of "continuous multi-timeslot resource selection," so that when m TBs arrive simultaneously at the physical layer of the terminal device, resources can be selected sequentially for each TB in the m TBs according to the determined resource selection order, thus determining m resources that are sequentially in the time domain, thereby achieving continuous multi-timeslot resource selection, reducing the impact of LBT failures, and improving channel access efficiency.

[0091] Figure 3 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 3 As shown, the method may include the following steps:

[0092] Step 301: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0093] Step 302: Determine the order of resource selection for m transport blocks (TB);

[0094] Step 303: Select resources for each of the m TBs in the determined order;

[0095] Step 304: If m resources that are temporally contiguous are selected for m TBs, then m TBs are continuously sent on the selected temporally contiguous m resources;

[0096] Step 305: If k resources that are temporally consecutive are selected from m TBs, where 1 < k < m and k is a positive integer, then the corresponding k TBs are sent consecutively on the selected k resources.

[0097] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0098] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer can refer to the Media Access Layer (MAC layer).

[0099] In summary, in the embodiments of this disclosure, m transport blocks (TBs) arriving simultaneously at the physical layer of the terminal device are determined, where m is a positive integer greater than 1; the resource selection order of the m transport blocks (TBs) is determined; resources are selected for each of the m TBs in the determined order; if m temporally consecutive resources are selected for the m TBs, then m TBs are continuously transmitted on the selected temporally consecutive m resources; if k temporally consecutive resources are selected for the m TBs, 1 < k < m, where k is a positive integer, then the corresponding k TBs are continuously transmitted on the selected k resources. In the embodiments of this disclosure, a continuous multi-timeslot resource selection mechanism is provided, reducing the situation where multiple TBs cannot be selected for continuous temporal resource selection when they arrive simultaneously, thus improving the convenience of continuous multi-timeslot resource selection. The embodiments of this disclosure specifically disclose a TB transmission scheme. This disclosure provides a processing method for a scenario of "continuous multi-timeslot resource selection". When m TBs reach the physical layer of the terminal device simultaneously, resources can be selected for each of the m TBs in a determined resource selection order. This can determine m resources that are continuous in the time domain, thereby realizing continuous multi-timeslot resource selection, reducing the impact of LBT failure, and improving channel access efficiency.

[0100] Figure 4 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 4 As shown, the method may include the following steps:

[0101] Step S401: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0102] Step S402: Determine the order of resource selection according to the number of resources in each TB's candidate resource set that are located in adjacent time slots with resources that have been selected by the higher layers of the terminal device but have not been used for actual transmission. Each time, the TB corresponding to the candidate resource set with the largest number of resources that are located in adjacent time slots with resources that have been selected by the higher layers of the terminal device but have not been used for actual transmission is selected.

[0103] Step S403: Select resources for each of the m TBs in the determined order.

[0104] Furthermore, in one embodiment of this disclosure, when selecting resources for any TB, if there are multiple TB candidate resource sets containing the same number of resources in adjacent time slots as the resources selected by the higher layers of the terminal device but not used for actual transmission, one TB can be randomly selected from the multiple TBs to select resources for any TB.

[0105] For example, in one embodiment of this disclosure, the terminal device randomly selects any one of m TBs and performs random resource selection in the candidate resource set corresponding to the any one TB. Resources that can be selected for initial transmission and retransmission are selected. Then, the terminal device has resources that have been selected but not used for actual transmission.

[0106] For example, in one embodiment of this disclosure, j resources are randomly selected for TB1, {r1, r2, r3, r4, ..., rj}, where j ≤ the maximum number of initial and retransmissions for one TB as indicated by the higher layer of the terminal device.

[0107] For example, in one embodiment of this disclosure, the terminal device can, one by one, determine the candidate resource set corresponding to the remaining TBs for which resource selection has not been performed, and determine the TB corresponding to the candidate resource set with the largest number of resources in adjacent time slots that are selected by one or more TBs in the higher layers of the terminal device and are not used for actual transmission. The terminal device can select resources for any TB, prioritizing resources in adjacent time slots that are selected by the higher layers of the terminal device and are not used for actual transmission. The resources selected for any TB and the existing resources in the higher layers of the terminal device are all called resources that are selected and not used for actual transmission. The terminal device can then determine again which TB's candidate resource set contains the TB corresponding to the candidate resource set with the largest number of resources in adjacent time slots that are selected by the higher layers of the terminal device and are not used for actual transmission. If so, it selects resources for any TB. This process is repeated until resource selection has been performed on each of the m TBs in the higher layers of the terminal device.

[0108] For example, in one embodiment of this disclosure, when 4 TBs arrive simultaneously, the physical layer of the terminal device can simultaneously report 4 candidate resource sets to the higher layers of the terminal device. These 4 candidate resource sets can be, for example, SA1, SA2, SA3, SA4, where m=4. The higher layers of the terminal device need to select resources that are consecutive in the time domain for 4 time slots. Assume that 5 resources are selected from each candidate resource set for initial transmission and retransmission. The higher layers of the terminal device randomly select a candidate resource set SA1 corresponding to one TB from the 4 candidate resource sets, such as TB1, and select 5 resources {r1, r2, r3, r4, r5} from this candidate resource set. The higher layers of the terminal device then evaluate each of the remaining 3 TBs corresponding to candidate resource sets SA2, SA3, and SA4, and find that candidate resource set SA3 contains the 3 most numerous resources that are located in adjacent time slots to the already selected resources. Therefore, resources {y1, y2, y3, y4, y5} are selected from SA3, where y1 and r1 form a... Adjacent time-slot resources: y2 and r2 form adjacent time-slot resources, y3 and r4 form adjacent time-slot resources, and y4 and y5 are not located in adjacent time slots with resources existing in the higher layers of the terminal device. Therefore, the resources currently selected but not used for data transmission in the higher layers of the terminal device are {r1y1, r2y2, r3, r4y3, r5, y4, y5}. The higher layers of the terminal device select resources from the remaining 2 TB corresponding to the candidate resource sets SA2 and SA4. It is found that the two resources with the largest number in candidate resource set SA2 are located in adjacent time slots with the selected resources. If resource y1 and x2 are in adjacent time slots, and resource y3 and x3, and resources x4 and x5 are not in adjacent time slots with resources in the higher layers of the terminal device, then resources {x1, x2, x3, x4, x5} are selected. Finally, resources {z1, z2, z3, z4, z5} are selected for TB4 in SA4. Z1 is in adjacent time slots with resource x1, and Z3 is in adjacent time slots with resource x2. Therefore, the higher layers of the terminal device have performed resource selection for all four TBs. The resources that have been selected but not used for actual transmission in the higher layers of the terminal device are {r1y1x1z1, r2y2, r3, z2, z4, r4y3x2z3, r5, x3, x4, x5, z5, y4, y5}. Therefore, the higher layers of the terminal device have selected two sets of resources with four consecutive time slots in the time domain: {r1y1x1z1, r4y3x2z3}.

[0109] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0110] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer can refer to the Media Access Layer (MAC layer).

[0111] In summary, in the embodiments of this disclosure, m transport blocks (TBs) arriving simultaneously at the physical layer of the terminal device are determined, where m is a positive integer greater than 1. The resource selection order is determined according to the number of resources in the candidate resource set of each TB that are located in adjacent time slots with resources already selected by the higher layers of the terminal device but not used for actual transmission. Each time, resources are selected from the TB corresponding to the candidate resource set with the largest number of resources in adjacent time slots with resources already selected by the higher layers of the terminal device but not used for actual transmission. Resources are selected sequentially from each of the m TBs in the determined order. This embodiment of the disclosure provides a continuous multi-time slot resource selection mechanism, reducing the situation where multiple TBs arrive simultaneously and multiple resource selections cannot be performed in a time-domain continuum, thus improving the convenience of continuous multi-time slot resource selection. Specifically, this embodiment of the disclosure discloses a scheme for determining the resource selection order based on the number of resources in the candidate resource set of each TB that are located in adjacent time slots with resources already selected by the higher layers of the terminal device but not used for actual transmission. This disclosure provides a processing method for a scenario of "continuous multi-timeslot resource selection". When m TBs reach the physical layer of the terminal device simultaneously, resources can be selected for each of the m TBs in a determined resource selection order. This can determine m resources that are continuous in the time domain, thereby realizing continuous multi-timeslot resource selection, reducing the impact of LBT failure, and improving channel access efficiency.

[0112] Figure 5 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 5 As shown, the method may include the following steps:

[0113] Step S501: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0114] Step S502: Determine the order of resource selection according to the priority of each TB;

[0115] Step S503: Select resources for each of the m TBs in the determined order.

[0116] For example, in one embodiment of this disclosure, if the priorities of the m TBs are all different, resource selection can be performed on the m TBs in descending or ascending order of their priorities. The priorities of the m TBs can be preset.

[0117] Furthermore, in one embodiment of this disclosure, according to the m TBs in descending order of priority, the terminal device first performs random resource selection for the TB with the highest priority in its corresponding candidate resource set, and then performs resource selection for the remaining TBs in their corresponding candidate resource sets in sequence. When selecting resources for each TB, the resources selected are located in adjacent time slots to one or more resources in the higher layers of the terminal device that have been selected but not used for actual transmission. The resources selected by each TB are all resources that have been selected but not used for actual transmission.

[0118] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0119] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer can refer to the Media Access Layer (MAC layer).

[0120] In summary, in the embodiments of this disclosure, m transport blocks (TBs) arriving simultaneously at the physical layer of the terminal device are determined, where m is a positive integer greater than 1; the resource selection order is determined according to the priority of each TB; and resources are selected for each of the m TBs in the determined order. This disclosure provides a continuous multi-timeslot resource selection mechanism, reducing the situation where multiple TBs cannot be selected consecutively in the time domain when they arrive simultaneously, thus improving the convenience of continuous multi-timeslot resource selection. Specifically, this disclosure discloses a scheme for determining the resource selection order according to the priority of each TB. This disclosure provides a processing method for a "continuous multi-timeslot resource selection" scenario, so that when m TBs arrive simultaneously at the physical layer of the terminal device, resources can be selected for each of the m TBs in the determined resource selection order, thereby determining m consecutive resources in the time domain, achieving continuous multi-timeslot resource selection, reducing the impact of LBT failures, and improving channel access efficiency.

[0121] Figure 6 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 6 As shown, the method may include the following steps:

[0122] Step S601: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0123] Step S602: Determine the order of resource selection according to the packet latency budget PDB value for each TB;

[0124] Step S603: Select resources for each of the m TBs in the determined order.

[0125] For example, in one embodiment of this disclosure, if the PDB values ​​of m TBs are all different, resource selection can be performed on the m TBs in ascending or descending order of PDB values. For instance, resource selection can be prioritized for TBs with small PDB values ​​and high latency requirements.

[0126] Furthermore, in one embodiment of this disclosure, the terminal device can first perform random resource selection for the TB with the smallest PDB value in its corresponding candidate resource set, in order of increasing PDB value, and then perform resource selection for the remaining TBs in their corresponding candidate resource sets in sequence. When selecting resources for each TB, resources located in adjacent time slots are selected from one or more resources in the higher layers of the terminal device that have been selected but not used for actual transmission. The resources selected for each TB are all resources that have been selected but not used for actual transmission.

[0127] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0128] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer can refer to the Media Access Layer (MAC layer).

[0129] In summary, in the embodiments of this disclosure, m transport blocks (TBs) arriving simultaneously at the physical layer of the terminal device are determined, where m is a positive integer greater than 1; the resource selection order is determined according to the packet delay budget (PDB) value of each TB; and resources are selected for each of the m TBs in the determined order. This disclosure provides a continuous multi-timeslot resource selection mechanism, reducing the situation where multiple TBs arrive simultaneously and cannot perform time-domain continuous resource selection, thus improving the convenience of continuous multi-timeslot resource selection. Specifically, this disclosure discloses a scheme for determining the resource selection order according to the packet delay budget (PDB) value of each TB. This disclosure provides a processing method for a "continuous multi-timeslot resource selection" scenario, so that when m TBs arrive simultaneously at the physical layer of the terminal device, resources can be selected for each of the m TBs in the determined resource selection order, thus determining m time-domain continuous resources, thereby achieving continuous multi-timeslot resource selection, reducing the impact of LBT failures, and improving channel access efficiency.

[0130] Figure 7 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 7 As shown, the method may include the following steps:

[0131] Step S701: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0132] Step S702: Determine the order of resource selection according to the Layer 1 destination ID value of each TB;

[0133] Step S703: Select resources for each of the m TBs in the determined order.

[0134] For example, in one embodiment of this disclosure, if the destination terminal devices of m TBs are different, resource selection is performed on the m TBs in ascending or descending order of their corresponding 16-bit Layer 1 destination ID values.

[0135] Furthermore, in one embodiment of this disclosure, the terminal device first performs random resource selection in its corresponding candidate resource set for the TB with the smallest or largest destination ID value, in ascending or descending order of Layer 1 destination ID values. Then, it sequentially performs resource selection in its corresponding candidate resource set for the remaining TBs. When selecting resources for each TB, it selects resources located in adjacent time slots to resources already selected by one or more TBs in the higher layers of the terminal device that have not been used for actual transmission. The resources selected for each TB are all resources that have been selected but not used for actual transmission.

[0136] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0137] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer can refer to the Media Access Layer (MAC layer).

[0138] In summary, in the embodiments of this disclosure, m transport blocks (TBs) arriving simultaneously at the physical layer of the terminal device are determined, where m is a positive integer greater than 1; the resource selection order is determined according to the Layer 1 destination ID value of each TB; and resources are selected for each of the m TBs in the determined order. This disclosure provides a continuous multi-timeslot resource selection mechanism, reducing the situation where multiple TBs cannot be selected consecutively in the time domain when they arrive simultaneously, thus improving the convenience of continuous multi-timeslot resource selection. Specifically, this disclosure discloses a scheme for determining the resource selection order according to the Layer 1 destination ID value of each TB. This disclosure provides a processing method for a "continuous multi-timeslot resource selection" scenario, so that when m TBs arrive simultaneously at the physical layer of the terminal device, resources can be selected for each of the m TBs in the determined resource selection order, thereby determining m consecutive resources in the time domain, achieving continuous multi-timeslot resource selection, reducing the impact of LBT failures, and improving channel access efficiency.

[0139] Figure 8 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 8 As shown, the method may include the following steps:

[0140] Step S801: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0141] Step S802: Determine the order of resource selection according to the time when the higher layer of the terminal device receives the candidate resource set for each TB;

[0142] Step S803: Select resources for each of the m TBs in the determined order.

[0143] Furthermore, in one embodiment of this disclosure, m resource blocks (TBs) arrive simultaneously without any order. The physical layer is triggered to select resources by the m TBs in slot n simultaneously. For the m TBs, the physical layer generates N candidate resource sets. However, the physical layer of the terminal device reports these N candidate resource sets (SAs), such as {SA1, SA2, ..., SAN}, to the higher layer of the terminal device at different times. The terminal device can determine the order of resource selection according to the time when the higher layer of the terminal device receives the candidate resource set for each TB.

[0144] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0145] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer can refer to the Media Access Layer (MAC layer).

[0146] In summary, in the embodiments of this disclosure, m transport blocks (TBs) that simultaneously arrive at the physical layer of the terminal device are determined, where m is a positive integer greater than 1; the resource selection order is determined according to the time when the higher layer of the terminal device receives the candidate resource set of each TB; and resources are selected for each of the m TBs in the determined order. This disclosure provides a continuous multi-timeslot resource selection mechanism, reducing the situation where multiple TBs arrive simultaneously and cannot perform time-domain continuous multi-resource selection, thus improving the convenience of continuous multi-timeslot resource selection. Specifically, this disclosure discloses a scheme for determining the resource selection order according to the time when the higher layer of the terminal device receives the candidate resource set of each TB. This disclosure provides a processing method for a "continuous multi-timeslot resource selection" scenario, so that when m TBs simultaneously arrive at the physical layer of the terminal device, resources can be selected for each of the m TBs in the determined resource selection order, thus determining the m time-domain continuous resources, thereby achieving continuous multi-timeslot resource selection, reducing the impact of LBT failures, and improving channel access efficiency.

[0147] Figure 9 This is a flowchart illustrating a continuous multi-timeslot resource selection method provided in an embodiment of this disclosure. The method is executed by a terminal device, such as... Figure 9 As shown, the method may include the following steps:

[0148] Step S901: Determine the m transport blocks TB that arrive at the physical layer of the terminal device simultaneously, where m is a positive integer greater than 1;

[0149] Step S902: Simultaneously, perform random resource selection from the candidate resource set of each of the m TBs, select resources for each TB, and the maximum length of the continuous time slot formed by the selected m resources in the time domain is L, where L is a positive integer.

[0150] In one embodiment of this disclosure...

[0151] If L = m, then use the m consecutive resources selected each time to send the corresponding m TBs;

[0152] If L=m is not satisfied, then random resource selection will be performed again for m TBs in the candidate resource set of each TB until L=m, or the number of times resources are reselected reaches the threshold.

[0153] Furthermore, in one embodiment of this disclosure, if the number of times resources are reselected reaches a threshold, the m resources with the largest L values ​​selected previously are used, and the corresponding m TBs are sent.

[0154] Furthermore, in one embodiment of this disclosure, the terminal device can send corresponding m TBs to the receiving terminal device, and the receiving terminal device can receive m TBs.

[0155] Furthermore, in one embodiment of this disclosure, each selected resource is a single-slot resource.

[0156] Furthermore, in one embodiment of this disclosure, the method is executed by a higher layer of the terminal device, which is another layer above the physical layer. That is, the higher layer is located above the physical layer. For example, the higher layer can refer to the Media Access Layer (MAC layer).

[0157] In summary, in the embodiments of this disclosure, m transport blocks (TBs) that simultaneously arrive at the physical layer of the terminal device are determined, where m is a positive integer greater than 1. Simultaneously, random resource selection is performed from the candidate resource set of each of the m TBs, selecting resources for each TB. The maximum length of the consecutive time slots formed by the selected m resources in the time domain is L, where L is a positive integer. This disclosure provides a continuous multi-time slot resource selection mechanism, reducing the situation where multiple TBs arrive simultaneously and making continuous multi-time slot resource selection impossible, thus improving the convenience of continuous multi-time slot resource selection. This disclosure provides a processing method for the scenario of "continuous multi-time slot resource selection," enabling random resource selection when m TBs simultaneously arrive at the physical layer of the terminal device. Resources are selected for each TB, and the maximum length of the consecutive time slots formed by the selected m resources in the time domain is L, thus determining continuous multi-time slot resource selection, reducing the impact of LBT failure, and improving channel access efficiency.
