[0003] Sidelink (SL) communication, as an emerging communications technology, is gaining increasing attention and widespread application. SL communication leverages edge computing and network resources to enable direct communication between different devices (e.g., user equipment (UE)). This eliminates the need for communication (e.g., service transmission) between different devices on the core network, reduces data transmission pressure on the core network, and conserves wireless spectrum resources. SL communication also reduces communication latency and significantly reduces network operating costs, leading to its increasing application in various fields.

[0031] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0032] It should be noted that, in this disclosure, words such as "exemplary" or "for example" are used to describe examples, illustrations, or explanations. Any embodiment or design described in this disclosure using words such as "exemplary" or "for example" should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0033] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0034] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0035] When a device conducts SL communications on unlicensed spectrum, it must first perform a channel access process to determine whether the selected channel is available. This means determining whether the device can effectively transmit information on the spectrum. However, the channel access process may be affected by other devices, causing the channel access process to fail for the device, effectively preventing it from conducting SL communications.

[0036] The resource determination method provided in the embodiment of the present disclosure can be applied to various communication systems. For example, the various communication systems can be device-to-device (D2D) communication systems, vehicle-to-everything (V2X) communication systems, or systems integrating multiple systems, etc., without limitation. The V2X communication system includes sub-fields such as vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), and vehicle-to-infrastructure (V2I). First, taking the communication system shown in Figure 1 as an example, the resource determination method provided in the embodiment of the present disclosure is described. Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided by the present disclosure.

[0037] As shown in Figure 1, the communication system includes multiple devices, and the multiple devices can communicate with each other. For example, the communication system includes: a first device 110, a second device 120, and a third device 130. The first device 110, the second device 120, and the third device 130 are connected to each other in pairs.

[0038] In some embodiments, the first device 110 is configured to perform data transmission based on SL communication. For example, when a service needs to be transmitted between the first device 110 and the second device 120, the service transmission between the first device 110 and the second device 120 may not pass through the network side, but the first device 110 may directly transmit the service to the second device 120.

[0039] In some embodiments, when the first device 110 needs to transmit data to the second device 120 based on time-frequency resources, it will first perform a channel access process to determine whether the selected channel is available (or whether the channel is idle). If the time interval during which the first device 110 performs the channel access process overlaps with the time interval during which the third device 130 performs data transmission, the channel access process of the first device 110 will fail, i.e., the channel will be unavailable. At this time, the first device 110 cannot transmit data to the second device 120 via SL communication.

[0040] In some embodiments, the channel may be a frequency domain resource with a bandwidth of 20 MHz, and the channel may belong to an unlicensed spectrum. In the unlicensed spectrum, during the process of performing channel access on one or more channels, a device may transmit data on the one or more channels only when the channels are assessed as available.

[0041] In some embodiments, the above-mentioned channel may include one or more resource blocks that can be used for information transmission, which are called resource block sets. In addition to resource block sets, a channel may also include other resource blocks used for guard bands.

[0042] In some embodiments, each device in the communication system (e.g., the first device 110) may be a UE (e.g., a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, and cellular phone), an augmented reality (AR) or virtual reality (VR) device, or other device with SL communication capabilities. The embodiments of the present disclosure do not impose any particular restrictions on the form of each device in the communication system.

[0043] It should be noted that the above scenarios are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Ordinary technicians in this field can know that with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0044] In a SL communication system, when services need to be transmitted between user devices, the services transmitted between the devices do not pass through the network side, that is, they do not pass through the forwarding of the cellular link between the device and the base station. Instead, the data source device transmits the services directly to the target device via SL. This mode of direct communication between devices has characteristics that are significantly different from the communication mode of traditional cellular systems. For short-range devices that can use SL communication, SL communication not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network, can reduce system resource usage, increase the spectrum efficiency of the cellular communication system, reduce communication latency, and significantly save network operating costs. In SL communication, devices can monitor the usage of resources within the resource pool and, based on the monitoring results, autonomously select resources within the resource pool for sending signaling / data.

[0045] When a device performs SL communication on an unlicensed spectrum, it should first perform a channel access process to determine whether the selected channel is available (or whether the channel is idle), that is, to determine whether the device can effectively transmit information on the spectrum resources. The channel access process is used for channel evaluation, and the result of the channel evaluation includes at least one of the following: channel idle, channel busy, channel unavailable, and channel available. A device can perform a channel access process on one or more channels to determine whether the channel is available. A channel here refers to a carrier or a part of a carrier consisting of a group of continuous resource blocks. The frequency domain resources corresponding to a channel here belong to the shared spectrum. The channel access process here can also be called a listen before talk (LBT) process. The first device determines whether the channel is occupied (or whether the channel is idle) through a channel access process for one or more channels. If the device determines that the channel is not occupied (or the channel is idle), it means that the device can use the channel for transmission and no LBT failure occurs (that is, LBT is successful). In some embodiments, the channel access process may include multiple types. For example, during the Type 1 channel access process, a counter N' is included. The initial value of the counter N' is a random value between 0 and the contention window (CW) value. During the Type 1 channel access process, the channel is considered available only when the number of idle detections reaches N'.

[0046] However, the channel access process may be affected by other devices, causing the channel access process of the device to fail, that is, causing the device to be unable to perform SL communication normally. For example, as shown in Figure 2, the time interval for UE1 to perform the channel access process is [t1, t2], and the time for UE2 to transmit is [t3, t4]. Since the time interval for UE2 to transmit overlaps with the time interval for UE1 to perform the channel access process, the channel access process of UE1 will fail, that is, UE1 will determine that the channel is unavailable, and thus will not allow UE1 to send SL information on the time-frequency resources in time slot n+3 in Figure 2. That is, even if the time-frequency resources used by UE1 and UE2 are orthogonal, UE2 may affect UE1's SL transmission. Furthermore, for the availability evaluation of a channel, UE1 determines whether the received energy on the channel exceeds a threshold value based on one or more judgments to determine whether the channel is available. When UE2's transmission overlaps with the time interval during which UE1 performs the channel access process, the receiving energy of UE1 on the channel will include the energy of UE2, which may cause UE1's receiving capability on the channel to exceed the threshold value, causing UE1's channel access process to fail, and ultimately causing UE1 to be unable to perform SL transmission.

[0047] UE2's transmission overlaps with UE1's channel access procedure, causing UE1's channel access procedure to fail. This is known as UE2's transmission blocking UE1's channel access, or UE2's transmission blocking UE1's LBT. This issue is particularly serious when UE1's sidelink transmission has a higher priority.

[0048] To address the above issues, see Figure 3, which is a flow chart of a resource determination method according to an embodiment of the present disclosure. As shown in Figure 3, the resource determination method provided by the embodiment of the present disclosure is applied to a first device and includes the following S101 to S103.

[0049] In S101, a first time-frequency resource is determined.

[0050] In some embodiments, the first time-frequency resource is a time-frequency resource reserved for the second device and is used for a first transmission of the second device. Exemplarily, the first transmission may be a first SL transmission. In the frequency domain, the frequency domain of the first time-frequency resource belongs to one or more resource block sets, each resource block set belonging to a channel; in the time domain, the first time-frequency resource includes one or more time slots.

[0051] In some embodiments, as shown in FIG4 , the above S101 , for example, may be implemented as: S1011 and S1012 .

[0052] In S1011, first indication information of the second device is received.

[0053] The first indication information is used to indicate the first time-frequency resource.

[0054] In some embodiments, the first indication information may be sidelink control information (SCI) of the second device. The SCI of the second device includes indication information of the time domain and the frequency domain of the first time-frequency resource.

[0055] In S1012, a first time-frequency resource is determined based on the first indication information.

[0056] In some embodiments, the first device may determine the first time-frequency resource reserved by the second terminal based on the time domain and frequency domain indication information of the first time-frequency resource in the first indication information.

[0057] It can be understood that in the method provided by the embodiment of the present disclosure, the first device can promptly determine the first time-frequency resource indicated in the first indication information by receiving the first indication information from the second device, so that the first device can further determine the first time-frequency area based on the first time-frequency resource.

[0058] It can be understood that the method provided in the embodiment of the present disclosure can timely determine the time-frequency resources reserved by the second device by determining the first time-frequency resources, so that the first device can further determine the area that will block the channel access corresponding to the communication transmission (for example, SL transmission) on the first time-frequency resources based on the first time-frequency resources, or determine the time-frequency area where the channel access is blocked by the communication transmission on the first time-frequency resources, so as to ensure that the first device or other devices can perform communication transmission normally.

[0059] In S102, a first time-frequency region is determined based on the first time-frequency resource.

[0060] The first time-frequency region includes at least one time slot in the time domain, at least one of which is adjacent to the time slot in which the first time-frequency resource is located. In the frequency domain, the first time-frequency region includes the resource block set or channel to which the first time-frequency resource belongs. For example, as shown in Figure 5, if the time domain in which the first time-frequency resource is located is slot 1, then the time domain in which the first time-frequency region is located may be slot 2; and if the resource block set to which the first time-frequency resource belongs is resource block set 1, then the first time-frequency region includes resource block set 1 in the frequency domain.

[0061] In some embodiments, the first time-frequency region includes at least one time slot immediately preceding the first time-frequency resource in the time domain, and / or includes at least one time slot immediately following the first time-frequency resource. For example, as shown in FIG6 , if the time domain in which the first time-frequency resource is located is slot 1, the first time-frequency region may include slots 2 and 3 in the time domain; or, as shown in FIG7 , if the time domain in which the first time-frequency resource is located is slot 1, the first time-frequency region may include slot 4 in the time domain.

[0062] It can be understood that the method provided by the embodiment of the present disclosure determines the first time-frequency region based on the first time-frequency resource, so that the time slots included in the first time-frequency region are adjacent to and do not overlap with the first time-frequency resource in the time domain. When the first time-frequency region includes at least one time slot immediately before the first time-frequency resource in the time domain, the first device can determine the area that blocks the channel access corresponding to the communication transmission of the first time-frequency resource. When the first time-frequency region includes at least one time slot immediately after the first time-frequency resource in the time domain, the first device can determine the area where channel access is blocked due to communication transmission on the first time-frequency resource.

[0063] In S103, a second time-frequency resource is determined based on the first time-frequency region.

[0064] In some embodiments, the second time-frequency resource may be a time-frequency resource to be selected by the first device, and the second time-frequency resource is used for a second transmission of the first device. Exemplarily, the second transmission may be a second SL transmission.

[0065] In some embodiments, as shown in FIG8 , the first device selects one or more time-frequency resources from several candidate time-frequency resources in the resource selection window, and each or all of the selected one or more time-frequency resources are marked as second time-frequency resources.

[0066] It should be noted that the resource selection window is a time window within which a device can select and request the required communication resources. The length of the resource selection window may vary based on actual needs, and the embodiments of this disclosure do not limit the length of the resource selection window.

[0067] As an implementation manner, the above S103, for example, can be implemented as: based on the first time-frequency region, determining that the second time-frequency resource is located outside the first time-frequency region.

[0068] As an example, if the first time-frequency region includes at least one time slot immediately preceding the first time-frequency resource in the time domain, when the first device determines the second time-frequency resource based on the first time-frequency region, the first device selects several time-frequency resources from several candidate time-frequency resources in the resource selection window as the second time-frequency resource. The second time-frequency resource is located outside the first time-frequency region, that is, the second time-frequency resource should be prevented from falling within the first time-frequency region.

[0069] It is understandable that before the second device uses the first time-frequency resource for communication transmission (for example, SL transmission), it is necessary to perform a channel access process to determine whether the first time-frequency resource is available. When the first time-frequency region includes at least one time slot immediately before the first time-frequency resource in the time domain, if there is a second transmission of the first device in the first time-frequency region, that is, if the second time-frequency resource is located in the first time-frequency region, then the second time-frequency resource will affect the second device before using the first time-frequency resource. The process of performing channel access causes the second device's channel access process to fail, thereby affecting the second device's normal communication transmission.

[0070] As another example, if the first time-frequency region includes at least one time slot immediately following the first time-frequency resource in the time domain, when the first device determines the second time-frequency resource based on the first time-frequency region, the first device selects several time-frequency resources from several candidate time-frequency resources in the resource selection window as the second time-frequency resource. The second time-frequency resource is located outside the first time-frequency region, that is, the second time-frequency resource should be prevented from falling within the first time-frequency region.

[0071] It is understandable that before the first device uses the second time-frequency resource for communication transmission (for example, SL transmission), it is necessary to perform a channel access process to determine whether the second time-frequency resource is available. When the first time-frequency region includes at least one time slot immediately following the first time-frequency resource in the time domain, if there is a second transmission of the first device in the first time-frequency region, that is, if the second time-frequency resource is located in the first time-frequency region, then the first time-frequency resource will affect the first device before using the second time-frequency resource. The process of performing channel access causes the first device's channel access process to fail, thereby affecting the first device's normal communication transmission.

[0072] As another implementation, the above-mentioned S103, for example, can be implemented as follows: determining the second time-frequency resource based on the first time-frequency region and the first condition. That is, the time-frequency positional relationship between the second time-frequency resource and the first time-frequency region can be flexibly determined based on whether the second time-frequency resource meets the first condition. In some embodiments, the second time-frequency resource meets at least one of the following: if the first condition is met, the second time-frequency resource is prohibited from being located in the first time-frequency region; if the first condition is not met, the second time-frequency resource is allowed to be located in the first time-frequency region.

[0073] In some embodiments, the first condition includes: the priority value of the second transmission is greater than the priority value of the first transmission. For example, the priority value of the second SL transmission may be greater than the priority value of the first SL transmission. The priority value of the first SL transmission is used to indicate the priority value included in the SCI of the first SL transmission; the priority value of the second SL transmission is used to indicate the priority value included in the SCI of the second SL transmission.

[0074] It should be noted that, in the embodiment of the present disclosure, the larger the priority value, the lower the priority; that is, if the priority value of the second transmission is greater than the priority value of the first transmission, it means that the priority of the second transmission is lower than the priority of the first transmission.

[0075] It can be understood that after determining the first time-frequency region, the method provided by the embodiment of the present disclosure is not limited to avoiding the second time-frequency resource being located in the first time-frequency region, but rather determines the positional relationship between the second time-frequency resource and the first time-frequency region in time and frequency based on whether the first transmission and the second transmission meet the first condition. This can make the determination of the second time-frequency resource more flexible, so as to facilitate more flexible allocation and scheduling of spectrum resources.

[0076] As another implementation, the above-mentioned step S103, for example, can be implemented as follows: determining the second time-frequency resource based on the first time-frequency region, the first condition, and the second condition. That is, the positional relationship between the second time-frequency resource and the first time-frequency region in time and frequency can be flexibly determined based on whether the second time-frequency resource meets the first condition and the second condition. In some embodiments, the second time-frequency resource meets at least one of the following: if the first condition is not met, the second time-frequency resource is allowed to be located in the first time-frequency region; if the second condition is met, the second time-frequency resource is allowed to be located in the first time-frequency region; if the second condition is not met and the first condition is met, the second time-frequency resource is prohibited from being located in the first time-frequency region.

[0077] In some embodiments, the second condition includes at least one of the following: a channel access priority class (CAPC) value of the second transmission is greater than or equal to the CAPC value of the first transmission; the destination IDs of the second transmission are the same as the source IDs of the first transmission, and the source IDs of the second transmission are the same as the destination IDs of the first transmission; the destination IDs of the second transmission are the same as the destination IDs of the first transmission.

[0078] In some embodiments, a smaller CAPC value indicates a higher access priority of the channel.

[0079] It can be understood that after determining the first time-frequency region, the method provided by the embodiment of the present disclosure is not limited to avoiding the second time-frequency resource being located in the first time-frequency region, but rather determines the positional relationship between the second time-frequency resource and the first time-frequency region in time and frequency based on the first condition and the second condition, which can make the determination of the second time-frequency resource more flexible, so as to facilitate more flexible allocation and scheduling of spectrum resources.

[0080] As an example, as shown in Figure 9, the second time-frequency resource is determined for the first device. The first time-frequency resource is located in slot m in the time domain and in resource block set 0 and resource block set 1 in the frequency domain. The first time-frequency region includes N slots immediately preceding the first time-frequency resource in the time domain, and includes resource block set 0 and resource block set 1 to which the first time-frequency resource belongs in the frequency domain. When the first device determines the second time-frequency resource from multiple candidate time-frequency resources, it determines whether the determined second time-frequency resource can be located in the first time-frequency region based on the first condition, or based on the first condition and the second condition. If it cannot fall within the first time-frequency region, then during the resource selection process, the second time-frequency resource determined by the first device should avoid falling into the first time-frequency region. That is, when the first device determines the second time-frequency resource from multiple candidate time-frequency resources, the first device determines the second time-frequency resource from the multiple candidate time-frequency resources that do not overlap with the first time-frequency region.

[0081] As another example, as shown in Figure 10, a second time-frequency resource is determined for the first device. The first time-frequency resource is located in slot m in the time domain and in resource block set 1 in the frequency domain. The first time-frequency region includes the N slots immediately preceding the first time-frequency resource in the time domain and includes resource block set 1 to which the first time-frequency resource belongs in the frequency domain. The method by which the first device determines the second time-frequency resource from multiple candidate time-frequency resources is consistent with the method in the above example and is not further described here.

[0082] As another example, as shown in Figure 11, a second time-frequency resource is determined for the first device. The first time-frequency resource is located in slot m in the time domain and in resource block set 0 and resource block set 1 in the frequency domain. The first time-frequency region includes the M slots immediately following the first time-frequency resource in the time domain and includes resource block set 0 and resource block set 1 to which the first time-frequency resource belongs in the frequency domain. The method by which the first device determines the second time-frequency resource from multiple candidate time-frequency resources is consistent with the method in the above example and will not be repeated here.

[0083] As another example, as shown in Figure 12, a second time-frequency resource is determined for the first device. The first time-frequency resource is located in slot m in the time domain and in resource block set 1 in the frequency domain. The first time-frequency region includes the M slots immediately following the first time-frequency resource in the time domain and includes resource block set 1 to which the first time-frequency resource belongs in the frequency domain. The method by which the first device determines the second time-frequency resource from multiple candidate time-frequency resources is consistent with the method in the above example and is not further described here.

[0084] It can be understood that, based on the resource determination method provided by the embodiment of the present disclosure, by determining the first time-frequency resource, the time-frequency resource on which communication transmission (for example, SL transmission) may be performed on the spectrum resource can be determined; at the same time, based on the first time-frequency resource, the first time-frequency region is determined, and the first time-frequency region includes at least one time slot in the time domain, and at least one time slot is adjacent to the time slot where the first time-frequency resource is located, so that the time slots included in the first time-frequency region are adjacent to the first time-frequency resource in the time domain and do not overlap. At this time, the first time-frequency region is the region that causes the channel access corresponding to the communication transmission on the first time-frequency resource to fail; or, the first time-frequency resource will cause the channel access corresponding to the communication transmission on the time-frequency resource within the first time-frequency region to fail. Finally, the first device determines the second time-frequency resource based on the first time-frequency region, and can determine the positional relationship between the second time-frequency resource and the first time-frequency region in time-frequency, thereby ensuring that the communication transmission on the second time-frequency resource will not affect the communication transmission on the first time-frequency resource; or, ensuring that the communication transmission on the first time-frequency resource will not affect the communication transmission on the second time-frequency resource, thereby ensuring that the first device or other devices perform communication transmission normally.

[0085] Referring to Figure 13, which is a flow chart of another resource determination method according to an embodiment of the present disclosure, as shown in Figure 13, the resource determination method provided by the embodiment of the present disclosure is applied to a first device, and can be implemented as the following S201 to S203, for example.

[0086] In S201, a third time-frequency resource is determined.

[0087] In some embodiments, the third time-frequency resource is used for a first transmission of the first device. For example, the first transmission of the first device may be a first SL transmission. In the frequency domain, the third time-frequency resource belongs to one or more resource block sets, each resource block set belonging to a channel; in the time domain, the third time-frequency resource includes one or more time slots.

[0088] In some embodiments, the third time-frequency resource is a time-frequency resource that has been previously selected by the first device. For example, the above S201 can be implemented as follows: the upper layer of the first device determines the third time-frequency resource from the time-frequency resources historically selected by the first device, and notifies the physical layer of the first device of the third time-frequency resource. That is, the upper layer of the first device determines all or part of the previously selected time-frequency resources as the third time-frequency resource, and provides the third time-frequency resource to the physical layer of the first device. Exemplarily, the upper layer of the first device can be other functional layers higher than the physical layer of the first device, for example, a media access control (MAC) layer.

[0089] It can be understood that the method provided by the embodiment of the present disclosure can timely determine the time-frequency resources previously selected by the first device by determining the third time-frequency resource, so that the first device can further determine the area that will cause the channel access corresponding to the communication transmission (for example, SL transmission) on the third time-frequency resource to fail based on the third time-frequency resource, or determine the time-frequency area where the channel access is blocked by the communication transmission on the third time-frequency resource, so as to ensure that the first device or other devices can perform communication transmission normally.

[0090] In S202, a second time-frequency region is determined based on the third time-frequency resource.

[0091] The second time-frequency region includes at least one time slot in the time domain, at least one time slot is adjacent to the time slot where the third time-frequency resource is located, and the second time-frequency region includes the resource block set or channel to which the third time-frequency resource belongs in the frequency domain.

[0092] In some embodiments, the implementation of S202 may refer to the above-mentioned S102, and the embodiments of the present disclosure will not be repeated here.

[0093] It can be understood that the method provided in the embodiment of the present disclosure determines the second time-frequency region based on the third time-frequency resource. The second time-frequency region may include at least one time slot immediately before the third time-frequency resource in the time domain, and / or include at least one time slot immediately after the third time-frequency resource. The time slots included in the second time-frequency region can be adjacent to and do not overlap with the third time-frequency resource in the time domain, thereby enabling the first device to determine the area where the channel access corresponding to the communication transmission on the third time-frequency resource is blocked; or, determine the area where the channel access is blocked due to the communication transmission on the third time-frequency resource.

[0094] In S203, based on the second time-frequency region, the situation of the third time-frequency resource is reported.

[0095] In some embodiments, the situation of the third time-frequency resource includes: re-evaluation of the third time-frequency resource and / or preemption of the third time-frequency resource. Reporting the situation of the third time-frequency resource includes: the physical layer of the first device reports the re-evaluation of the third time-frequency resource to the upper layer of the first device; and / or the physical layer of the first device reports the preemption of the third time-frequency resource to the upper layer of the first device. Reporting the re-evaluation of the third time-frequency resource means that the third time-frequency resource is unavailable; reporting that the third time-frequency resource is preempted means that the third time-frequency resource is preempted by SL transmission of a higher priority (i.e., a lower priority value) of other user devices, and the third time-frequency resource is unavailable.

[0096] As an example, a higher layer of a first device notifies a physical layer of the first device of time-frequency resources (r0, r1, r2, ...) that may be re-evaluated, and the physical layer of the first device reports the re-evaluation of at least one time-frequency resource in (r0, r1, r2, ...) to the higher layer of the first device. (r0, r1, r2, ...) represents one or more time-frequency resources. The first device may mark the re-evaluated time-frequency resource in (r0, r1, r2, ...) reported by the physical layer of the first device to the higher layer of the first device as a third time-frequency resource.

[0097] As another example, the upper layer of the first device notifies the physical layer of the first device of the time-frequency resources (r′0, r′1, r′2, ...) that may be preempted, and the physical layer of the first device reports the preemption of at least one of the time-frequency resources (r′0, r′1, r′2, ...) to its upper layer. ′ , r′1, r′2, …) represent one or more time-frequency resources. The first device can mark the preempted time-frequency resources among (r′0, r′1, r′2, …) reported by the physical layer of the first device to the upper layer of the first device as third time-frequency resources. The first device reporting the preemption of the third time-frequency resource indicates that the third time-frequency resource is preempted by the third SL transmission of a higher priority of the third device.

[0098] It can be understood that in the method provided by the embodiment of the present disclosure, the first device promptly reports the situation of the third time-frequency resource based on the second time-frequency area, and can promptly determine whether the third time-frequency resource needs to be re-evaluated or whether the third time-frequency resource is preempted, and then determine whether the third time-frequency resource is available to ensure normal communication transmission of the first device.

[0099] In some embodiments, the above S203 may be implemented, for example, as follows: reporting the situation of the third time-frequency resource based on the second time-frequency region and the fourth time-frequency resource.

[0100] In some embodiments, the fourth time-frequency resource is a time-frequency resource reserved for the third device, and the fourth time-frequency resource is used for the third transmission of the third device. Exemplarily, the third transmission of the third device may be a third SL transmission.

[0101] As an implementation method, based on the second time-frequency region and the fourth time-frequency resource, the situation of the third time-frequency resource is reported, including: when the third condition is met, the physical layer of the first device reports the situation of the third time-frequency resource to the high-level layer of the first device; or, when the third condition is not met, the physical layer of the first device does not report the situation of the third time-frequency resource to the high-level layer of the first device.

[0102] In some embodiments, the third condition includes: the fourth time-frequency resource is located in the second time-frequency region.

[0103] In some embodiments, if the first device reports a re-evaluation of the third time-frequency resource, the third condition further includes: the fourth time-frequency resource does not belong to a resource set. The above-mentioned resource set refers to the remaining resources after the first device excludes resources in the resource selection window. The first device excludes resources at least including: the first device excludes time-frequency resources whose reference signal received power (RSRP) is greater than a threshold value. Exemplarily, the threshold value can be -100dBm.

[0104] In some embodiments, if the first device reports the preemption of the third time-frequency resource, the third condition also includes: the fourth time-frequency resource does not belong to a resource set. The above-mentioned resource set refers to the remaining resources after the first device performs resource exclusion in the resource selection window. The first device performs resource exclusion at least including: the first device excludes time-frequency resources whose RSRP is greater than the threshold value. Exemplarily, the threshold value can be -100dBm. Furthermore, the third condition may also include at least one of the following: the priority value of the third SL transmission is less than the priority value of the first SL transmission; the radio resource control (RRC) layer signaling received by the first device is configured with preemption enable; the priority value of the third SL transmission is less than the priority value of the first SL transmission, and the priority value of the third SL transmission is less than a threshold value. The smaller the priority value, the higher the priority. The priority value of the third SL transmission is the priority value included in the SCI used by the third device to indicate the third SL transmission. The priority value of the first SL transmission is the priority value included in the SCI used by the first device to indicate the first SL transmission.

[0105] As an example, as shown in Figure 14, the first device determines the third time-frequency resource and the second time-frequency region. The third time-frequency resource is located in resource block set 0 and resource block set 1 in the frequency domain. The second time-frequency region includes resource block set 0 and resource block set 1 to which the third time-frequency resource belongs in the frequency domain; and includes N slots immediately before the third time-frequency resource in the time domain. The third device indicates the reserved fourth time-frequency resource through SCI. If the fourth time-frequency resource is located in the second time-frequency region at this time, and the RSRP corresponding to the fourth time-frequency resource measured by the first device is greater than the threshold value, the third condition is met. At this time, the physical layer of the first device reports to its upper layer the re-evaluation and / or preemption of the third time-frequency resource. The upper layer of the first device decides that the first device does not use the third time-frequency resource for SL transmission.

[0106] As another example, as shown in Figure 15, the first device determines the third time-frequency resource and the second time-frequency region. The third time-frequency resource is located in the resource block set 1 in the frequency domain, and the second time-frequency region includes the resource block set 1 to which the third time-frequency resource belongs in the frequency domain, and includes the N slots immediately before the third time-frequency resource in the time domain. The third device indicates the reserved fourth time-frequency resource through the SCI. If the fourth time-frequency resource does not fall into the second time-frequency region at this time, the third condition is not met. That is, the first device believes that the third time-frequency resource is available, and the physical layer of the first device does not report the re-evaluation and / or preemption of the third time-frequency resource to the upper layer.

[0107] It can be understood that if the second time-frequency region includes several time slots immediately before the third time-frequency resource in the time domain, and the fourth time-frequency resource falls within the second time-frequency region, then the communication transmission within the fourth time-frequency resource will affect the first device's channel access process before using the third time-frequency resource for communication transmission (such as SL transmission), which will cause the first device's channel access process to fail, and thus make the third time-frequency resource unavailable, that is, the first device cannot perform normal communication transmission.

[0108] As another implementation method, based on the second time-frequency region and the fourth time-frequency resource, reporting the situation of the third time-frequency resource includes at least one of the following: when the third condition is not met, the physical layer of the first device does not report the situation of the third time-frequency resource to the upper layer of the first device; when the fourth condition is met, the physical layer of the first device does not report the situation of the third time-frequency resource to the upper layer of the first device; when the fourth condition is not met and the third condition is met, the physical layer of the first device reports the situation of the third time-frequency resource to the upper layer of the first device.

[0109] In some embodiments, the fourth condition includes at least one of the following: the CAPC value of the third transmission is greater than or equal to the CAPC value of the first transmission; the source identifier of the third transmission is the same as the target identifier of the first transmission, and the target identifier of the third transmission is the same as the source identifier of the first transmission; the target identifier of the third transmission is the same as the target identifier of the first transmission.

[0110] As an example, if the second time-frequency region and the fourth time-frequency resources do not meet the fourth condition, the physical layer of the first device reports the re-evaluation of the third time-frequency resources to its upper layer, and the upper layer of the first device decides that the first device does not use the third time-frequency resources for SL transmission.

[0111] As another example, if the second time-frequency region and the fourth time-frequency resource meet the fourth condition, regardless of whether they meet the third condition, the physical layer of the first device does not report the re-evaluation of the third time-frequency resource to its upper layer, and the first device can use the third time-frequency resource for the first SL transmission.

[0112] In some embodiments, when the source identifier of the third transmission is the same as the destination identifier of the first transmission, and the destination identifier of the third transmission is the same as the source identifier of the first transmission, the first SL transmission and the third SL transmission can each be a unicast transmission. Unicast transmission refers to a point-to-point communication method in network communication that transmits data from a sender to a specific receiver. In unicast transmission, data is only sent to a specific destination address in the network, ensuring the privacy of the data and the clarity of the destination.

[0113] In some embodiments, when the target identifier of the third transmission is the same as the target identifier of the first transmission, the first SL transmission and the third SL transmission may be broadcast transmissions, or may be multicast transmissions, respectively.

[0114] In some embodiments, the target identifier and the source identifier may respectively represent the target identifier and the source identifier used to indicate the reception of the physical sidelink shared channel (PSSCH), and may also respectively represent the additional target identifier and the additional source identifier used to indicate the COT sharing in the channel occupying time (COT) sharing information indication.

[0115] It can be understood that after determining the second time-frequency region, the method provided by the embodiment of the present disclosure is not limited to reporting the third time-frequency resource when the fourth time-frequency resource is located in the second time-frequency region, but rather determines whether to report the third time-frequency resource based on whether the first transmission and the third transmission meet different conditions, such as whether to report the re-evaluation or preemption of the third time-frequency resource, so that the first device can promptly determine whether the third time-frequency resource is available, and ensure that the first device performs normal communication transmission (such as SL transmission).

[0116] It can be understood that based on the resource determination method provided by the embodiment of the present disclosure, by determining the third time-frequency resource, the time-frequency resource on which communication transmission (such as SL transmission) may be carried out on the spectrum resource can be determined; at the same time, based on the third time-frequency resource, the first time-frequency area is determined, and the second time-frequency area includes at least one time slot in the time domain, and at least one time slot is adjacent to the time slot where the third time-frequency resource is located, so that the time slots included in the second time-frequency area and the third time-frequency resource are adjacent in the time domain and do not overlap. At this time, the second time-frequency area is the area that causes the channel access corresponding to the communication transmission on the third time-frequency resource to fail; or, the third time-frequency resource will cause the channel access corresponding to the communication transmission of the time-frequency resources in the second time-frequency area to fail. Finally, based on the second time-frequency region, reporting the situation of the third time-frequency resource can facilitate the first device to determine whether the channel access corresponding to the communication transmission of the third time-frequency resource will be blocked based on whether there are time-frequency resources used for communication transmission in the second time-frequency region, or whether the communication transmission on the third time-frequency resource blocks the channel access corresponding to the communication transmission of other devices in the second time-frequency region, and then promptly report the situation of the third time-frequency resource to determine whether the third time-frequency resource is available, to ensure that the first device or other devices can perform communication transmission normally.

[0117] The above mainly introduces the scheme of the embodiment of the present disclosure from the perspective of method. It can be understood that in order to realize the above functions, the resource determination device includes at least one of the hardware structure and software modules corresponding to the execution of each function.

In some embodiments, the communication device 500 may also include a communication interface 503.

The processor 502 may also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of a DSP (digital signal processor) and a microprocessor, and the like.

[0148] The communication interface 503 is used to connect to other devices via a communication network, such as Ethernet, wireless access network, or wireless local area network (WLAN).

[0149] The memory 501 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

[0153] Some embodiments of the present disclosure provide a computer-readable storage medium (e.g., a non-transitory computer-readable storage medium) having computer program instructions stored therein. When the computer program instructions are executed on a computer, the computer executes a resource determination method as in any of the above embodiments.

[0155] An embodiment of the present disclosure provides a computer program product comprising instructions. When the computer program product is run on a computer, the computer is enabled to execute the resource determination method of any one of the above embodiments.

[0156] Based on the resource determination method provided by the embodiment of the present disclosure, by determining the first time-frequency resource, the time-frequency resource on which communication transmission (such as SL transmission) may be performed on the spectrum resource can be determined; at the same time, based on the first time-frequency resource, the first time-frequency region is determined, and the first time-frequency region includes at least one time slot in the time domain, and at least one time slot is adjacent to the time slot where the first time-frequency resource is located, so that the time slots included in the first time-frequency region are adjacent to the first time-frequency resource in the time domain and do not overlap. At this time, the first time-frequency region is the region that causes the failure of channel access corresponding to communication transmission on the first time-frequency resource; or, the first time-frequency resource causes the failure of channel access corresponding to communication transmission on the time-frequency resources within the first time-frequency region. Finally, the first device determines the second time-frequency resource based on the first time-frequency region, and can determine the positional relationship between the second time-frequency resource and the first time-frequency region in time and frequency, thereby ensuring that the communication transmission on the second time-frequency resource will not affect the communication transmission on the first time-frequency resource; or, ensuring that the communication transmission on the first time-frequency resource will not affect the communication transmission on the second time-frequency resource, thereby ensuring that the first device or other devices perform communication transmission normally.

[0157] In addition, based on the resource determination method provided by the embodiment of the present disclosure, by determining the third time-frequency resource, the time-frequency resource on the spectrum resource where communication transmission (such as SL transmission) may be carried out can be determined; at the same time, based on the third time-frequency resource, the second time-frequency area is determined, and the second time-frequency area includes at least one time slot in the time domain, and at least one time slot is adjacent to the time slot where the third time-frequency resource is located, so that the time slots included in the second time-frequency area and the third time-frequency resource are adjacent in the time domain and do not overlap. At this time, the second time-frequency area is the area that causes the channel access corresponding to the communication transmission on the third time-frequency resource to fail; or, the third time-frequency resource will cause the channel access corresponding to the communication transmission of the time-frequency resources in the second time-frequency area to fail. Finally, based on the second time-frequency region, reporting the situation of the third time-frequency resource can facilitate the first device to determine whether the third time-frequency resource will fail to communicate due to blocked channel access, or whether the third time-frequency resource will block the channel access corresponding to the communication transmission of other devices in the second time-frequency region, based on whether there are time-frequency resources used for communication transmission in the second time-frequency region, and then promptly report the situation of the third time-frequency resource to determine whether the third time-frequency resource is available, to ensure that the first device or other devices can communicate and transmit normally.

[0158] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or replacements within the technical scope disclosed in the present disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
