Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a resource allocation method and apparatus. Background Technology

[0002] In NR (New Radio) systems, channel monitoring is performed on unlicensed frequency bands of the sidelink (SL). The sidelink synchronization signal block (S-SSB) is only transmitted when the channel is detected to be idle.

[0199] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0200] To better understand the resource allocation method disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is described below.

[0201] Please see Figure 1 , Figure 1 This application provides a schematic diagram of the architecture of a communication system. The communication system may include, but is not limited to, a first network device, a second network device, and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In actual applications, it may include two or more network devices and two or more terminal devices. Figure 1 The communication system shown is exemplified by a network device 101 and a terminal device 102.

[0202] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, fifth-generation mobile communication systems, 5G New Radio systems, or other future new mobile communication systems.

[0203] The network device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a Transmission Reception Point (TRP), a Next Generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a Wireless Fidelity (WiFi) system. This embodiment does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a Central Unit (CU) and a Distributed Unit (DU). The CU can also be called a Control Unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0204] In this application embodiment, the terminal device 102 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0205] In an NR (New Radio) system, within a sidelink licensed frequency band, one sidelink synchronization signal block (S-SSB) cycle supports the transmission of N S-SSBs (N>1, where N is a positive integer). Each S-SSB occupies one time slot. Network device 101 configures a total of N fixed time-domain resources for these N S-SSBs. Terminal device 102 can determine the configured N time-domain resources through parameters.

[0206] In the unlicensed frequency band of the direct link, terminal device 102 performs channel monitoring based on the listen-before-talk (LBT) mechanism. Only when the channel is detected to be idle can it send the sidelink synchronization signal block (S-SSB).

[0207] In related technologies, when the direct link operates in a licensed frequency band, the resource configuration for transmitting S-SSBs is fixed, such as in NRv2x (vehicle-to-everything). When the direct link operates in an unlicensed frequency band, if the S-SSB resources are still configured in a fixed and limited resource location, the terminal device 102 performs LBT (Local Level Bypass) at that location. If LBT fails, S-SSBs cannot be transmitted. Due to the uncertainty of the LBT result, the success rate of S-SSB transmission cannot be guaranteed.

[0208] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0209] The resource allocation method and apparatus provided in this application will be described in detail below with reference to the accompanying drawings.

[0210] Please see Figure 2 , Figure 2 This is a flowchart illustrating a resource allocation method provided in an embodiment of this application. It should be noted that the resource allocation method in this embodiment is applied to unlicensed frequency bands and is executed by a terminal device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 2 As shown, the method may include the following steps:

[0211] Step 201: Receive resource configuration information sent by the network device.

[0212] In the embodiments of the application, the terminal device can receive resource configuration information sent by the network device, which is used to determine multiple candidate resources. These multiple candidate resources are used to send the Direct Link Synchronization Signal Block (S-SSB).

[0213] In some implementations, the resource configuration information includes at least one of time-domain resource indication information and frequency-domain configuration information.

[0214] Among them, the time-domain resource indication information is used to determine multiple time-domain candidate resources, and the frequency-domain resource indication information is used to determine at least one frequency-domain candidate resource.

[0215] That is, as the first possible implementation, the resource configuration information includes time-domain resource indication information.

[0216] As a second possible implementation, the resource configuration information includes frequency domain resource indication information.

[0217] As a third possible implementation, the resource configuration information includes time-domain resource indication information and frequency-domain configuration information.

[0218] Step 202: Based on the resource configuration information, determine multiple time-domain candidate resources and / or at least one frequency-domain candidate resource. These multiple time-domain candidate resources and / or at least one frequency-domain candidate resource are used to transmit the direct link synchronization signal block S-SSB.

[0219] In this embodiment of the application, the terminal device can determine multiple time-domain candidate resources and / or at least one frequency-domain candidate resource based on the received resource configuration information. The time-domain candidate resource and the frequency-domain candidate resource are resources used to transmit the direct link synchronization signal block S-SSB.

[0220] As a first possible implementation, the resource configuration information includes time-domain resource indication information, and the terminal device can determine multiple time-domain candidate resources based on the resource configuration information.

[0221] As a second possible implementation, the resource configuration information includes frequency domain resource indication information, and the terminal device can determine at least one frequency domain candidate resource based on the resource configuration information.

[0222] As a third possible implementation, the resource configuration information includes time-domain resource indication information and frequency-domain configuration information. The terminal device can determine multiple time-domain candidate resources and at least one frequency-domain candidate resource based on the resource configuration information.

[0223] In some implementations, the plurality of candidate resources includes a target resource, on which the terminal device sends an S-SSB.

[0224] In this embodiment, the terminal device is capable of monitoring time-domain / frequency-domain candidate resources. It should be noted that monitoring resources by the terminal device refers to performing LBT (Low-Level Bit-Test) on the channel corresponding to the candidate resource.

[0225] If the time-domain / frequency-domain candidate resource is detected as idle (LBT success, meaning the channel corresponding to the candidate resource is idle), then the time-domain / frequency-domain candidate resource is the target resource, and S-SSB can be transmitted on it. If the time-domain / frequency-domain candidate resource is detected as busy (LBT failure, meaning the channel corresponding to the candidate time-domain / frequency-domain resource is busy), then S-SSB cannot be transmitted on it. In other words, the target resource for transmitting S-SSB is at least one time-domain / frequency-domain candidate resource that is detected as idle.

[0226] Optionally, in the embodiments of this application, the frequency domain location of the plurality of time-domain candidate resources may be on a designated LBT sub-band configured in the network device, or on at least one frequency-domain candidate resource, wherein the designated LBT sub-band has a different frequency from the at least one frequency-domain candidate resource.

[0227] In summary, by receiving resource configuration information sent by network devices, and determining multiple time-domain candidate resources and / or at least one frequency-domain candidate resource based on this resource configuration information, these multiple time-domain candidate resources and / or at least one frequency-domain candidate resource are used to transmit the direct link synchronization signal block S-SSB. This enables the terminal device to determine multiple candidate resources and transmit the S-SSB from among these multiple candidate resources, which can significantly and effectively improve the transmission success rate of the direct link synchronization signal block S-SSB in unlicensed frequency bands and improve system communication efficiency.

[0228] Please see Figure 3 , Figure 3 This is a flowchart illustrating a resource allocation method provided in an embodiment of this application. It should be noted that the resource allocation method in this embodiment is applied to unlicensed frequency bands and is executed by a terminal device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 3 As shown, the method may include the following steps:

[0229] Step 301: Receive resource configuration information sent by the network device.

[0230] In this embodiment, the resource configuration information includes time-domain resource indication information. The terminal device can determine multiple time-domain candidate resources by receiving the time-domain resource indication information.

[0231] Step 302: Based on the resource configuration information, determine multiple time-domain candidate resources.

[0232] In this embodiment of the application, the resource configuration information includes time-domain resource indication information, which includes: first time-domain resource indication information, second time-domain resource indication information, and third time-domain resource indication information.

[0233] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource relative to the start position of the S-SSB cycle among multiple time-domain candidate resources in an S-SSB cycle.

[0234] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resources among multiple time-domain candidate resources in the S-SSB period;

[0235] The third time-domain resource indication information is used to indicate the number of time-domain candidate resources in the S-SSB period, wherein the number of time-domain candidate resources in the S-SSB period is greater than the number of S-SSBs that can be transmitted in the S-SSB period.

[0236] That is, in the embodiments of this application, the network device configures m time-domain candidate resources for the terminal device in one S-SSB cycle, where m>N, m is a positive integer, and N is the number of S-SSBs that can be sent in one S-SSB cycle, where N is a positive integer.

[0237] The temporal location of these m temporal candidate resources can be determined by the first temporal resource indication information, the second temporal resource indication information, and the third temporal resource indication information.

[0238] In some implementations, the first time-domain resource indication information may be the parameter sl-timeoffsetssb in the R16 direct sidelink, or it may be other newly defined parameters used to indicate the offset of the first time-domain candidate resource among the m time-domain candidate resources in the S-SSB cycle relative to the start position of the S-SSB cycle.

[0239] In some implementations, the second time-domain resource indication information may be the parameter sl-timeinterval from the R16 direct sidelink, or it may be other newly defined parameters used to indicate the time interval between every two time-domain candidate resources among the m time-domain candidate resources within the S-SSB period. Optionally, the unit of this time interval may be a time slot, or other granular units may be selected depending on the resource configuration.

[0240] The third time-domain resource indication information can indicate the number m of time-domain candidate resources within the S-SSB period, and the third time-domain resource indication information can be a newly defined parameter.

[0241] Optionally, the value of m can be predefined by the network device, with the third time domain resource indication information directly indicating the value of m, or it can be a value in a pre-configured set, where the third time domain resource indication information can indicate an index in the set.

[0242] As an example, please see Figure 4a , Figure 4a This is a schematic diagram of a resource allocation method provided in an embodiment of this application. For example... Figure 4a As shown, the network device configures m time-domain candidate resources for the terminal device within one S-SSB cycle. As an example, m = 9. The number of S-SSBs that can be sent within one S-SSB cycle is N. As an example, N = 4.

[0243] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource (resource p1 in the figure) in the S-SSB cycle relative to the starting position of the S-SSB cycle.

[0244] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resources among the m time-domain candidate resources in the S-SSB period.

[0245] In some embodiments of this application, the frequency domain location of the plurality of time-domain candidate resources is on a specified LBT subband configured in the network device, or it may be on at least one frequency-domain candidate resource.

[0246] Step 303: Monitor the multiple time-domain candidate resources within the S-SSB period, with the target resource being at least one idle time-domain candidate resource.

[0247] The target resource is the resource included among the multiple time-domain candidate resources used to send the S-SSB.

[0248] In this embodiment, the terminal device monitors the multiple time-domain candidate resources within the determined S-SSB period. It should be noted that, in this embodiment, monitoring the resources by the terminal device refers to performing LBT on the channel corresponding to the candidate resource.

[0249] If the time-domain / frequency-domain candidate resource is detected as idle (LBT success, meaning the channel corresponding to the candidate resource is idle), then the time-domain / frequency-domain candidate resource is the target resource, and S-SSB can be transmitted on it. If the time-domain / frequency-domain candidate resource is detected as busy (LBT failure, meaning the channel corresponding to the candidate time-domain / frequency-domain resource is busy), then S-SSB cannot be transmitted on it. In other words, the target resource for transmitting S-SSB is at least one time-domain / frequency-domain candidate resource that is detected as idle.

[0250] It is understood that in this embodiment of the application, the terminal device can only transmit data and send S-SSB on the resource if it detects that the resource is idle, that is, LBT is successful.

[0251] As an example, such as Figure 4a As shown, the terminal device performs LBT on m time-domain candidate resources within the S-SSB period. The first time-domain candidate resource (resource p1) is detected as busy, meaning the LBT fails. The second time-domain candidate resource (resource p2) is detected as idle, meaning the LBT succeeds, and resource p2 becomes the target resource. Similarly, the third time-domain candidate resource (resource p3) fails the LBT, while the fourth and fifth time-domain candidate resources (resource p4 and resource p5) succeed, and resources p4 and p5 become the target resources. The sixth and seventh time-domain candidate resources (resource p6 and resource p7) fail the LBT, while the eighth time-domain candidate resource (resource p8) succeeds, and resource p8 becomes the target resource.

[0252] In this embodiment of the application, if the number of idle time-domain candidate resources detected is equal to the number of S-SSBs that can be sent within the S-SSB period, then steps 304 and 305 are executed; if the number of idle time-domain candidate resources detected is less than the number of S-SSBs that can be sent within the S-SSB period, then step 306 is executed.

[0253] Step 304: Send the S-SSB for the S-SSB period on the target resource.

[0254] Step 305: Stop monitoring the remaining temporal candidate resources.

[0255] In this embodiment of the application, the terminal device can send the S-SSB within the S-SSB period on the target resource that is idle, that is, the LBT success.

[0256] In this embodiment, the number of idle time-domain candidate resources detected is equal to the number of S-SSBs that can be transmitted within the S-SSB cycle. That is, after the terminal device successfully performs LBT on a candidate resource among the multiple time-domain candidate resources, the number of time-domain candidate resources that have been successfully LBTed is equal to the number of S-SSBs within the S-SSB cycle. In other words, the terminal device is already able to transmit all S-SSBs within the S-SSB cycle.

[0257] In this embodiment of the application, since the terminal device has been able to send all S-SSBs within the S-SSB period, if there are still remaining time-domain candidate resources, the terminal device will stop listening to the remaining time-domain candidate resources and will no longer perform LBT on the remaining time-domain candidate resources.

[0258] As an example, such as Figure 4a As shown, the terminal device successfully performs LBT on resources p2, p4, p5, and p8, and sends the S-SSB within that S-SSB period. After the successful LBT on resource p8, the number of time-domain candidate resources that have been successfully LBTed is 4, and the terminal device is now able to send all 4 S-SSBs within that period. The terminal device stops listening to the remaining time-domain candidate resources and will not perform LBT on the ninth time-domain candidate resource (resource p9).

[0259] Step 306: Send a portion of the S-SSBs within the S-SSB period on idle time-domain candidate resources.

[0260] In this embodiment of the application, if the number of idle time-domain candidate resources is less than the number of S-SSBs that can be sent within the S-SSB period, the terminal device will send a portion of the S-SSBs within the S-SSB period on the idle time-domain candidate resources.

[0261] As an example, please see Figure 4b , Figure 4b This is a schematic diagram of a resource allocation method provided in an embodiment of this application. For example... Figure 4b As shown, the network device configures m time-domain candidate resources for the terminal device within one S-SSB cycle. As an example, m = 9. The number of S-SSBs that can be sent within one S-SSB cycle is N. As an example, N = 4.

[0262] Terminal equipment Figure 4bIf LBT succeeds on resources p2, p4, and p5, but LBT fails on resources p6, p7, p8, and p9, it means that the terminal device detected 3 idle time-domain candidate resources during the S-SSB cycle, which is less than the number of S-SSBs during the S-SSB cycle. Therefore, the terminal device only sent 3 S-SSBs on the three idle resources p2, p4, and p5 during the S-SSB cycle, meaning that only a portion of the S-SSBs were sent.

[0263] It should be noted that in steps 304 and 306 of this application embodiment, the S-SSBs are sent in the order of their sequence numbers within the S-SSB period, that is, in the first idle time domain resource detected. Figure 4a and Figure 4b The first S-SSB is sent on resource p2), and the second idle time domain resource is detected. Figure 4a and Figure 4b Send the second S-SSB on resource p4, etc.

[0264] In summary, by receiving resource configuration information from network devices, multiple time-domain candidate resources are identified based on this information. These candidate resources within the S-SSB cycle are monitored, with the target resource being at least one idle candidate resource. If the number of idle candidate resources is equal to the number of S-SSBs within the S-SSB cycle, S-SSBs within the S-SSB cycle are transmitted on the target resource, and monitoring of the remaining candidate resources ceases. If the number of idle candidate resources is less than the number of S-SSBs within the S-SSB cycle, a portion of the S-SSBs within the S-SSB cycle are transmitted on the idle candidate resources. This allows the terminal device to identify more candidate resources than the number of S-SSBs to be transmitted and to transmit S-SSBs from these candidate resources. This significantly and effectively improves the transmission success rate of S-SSBs for direct-link synchronization signals in unlicensed frequency bands, thereby increasing system communication efficiency.

[0265] Please see Figure 5 , Figure 5 This is a flowchart illustrating a resource allocation method provided in an embodiment of this application. It should be noted that the resource allocation method in this embodiment is applied to unlicensed frequency bands and is executed by a terminal device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 5 As shown, the method may include the following steps:

[0266] Step 501: Receive resource configuration information sent by the network device.

[0267] In an embodiment of the present application, the resource configuration information includes time domain resource indication information. The terminal device can determine multiple time domain candidate resources by receiving the time domain resource indication information.

[0268] Step 502: Determine multiple time domain candidate resources according to the resource configuration information.

[0269] In an embodiment of the present application, the resource configuration information includes time domain resource indication information, and the time domain resource indication information includes: first time domain resource indication information, second time domain resource indication information, and third time domain resource indication information.

[0270] Among them, the first time domain resource indication information is used to indicate the offset of the first time domain candidate resource in the first group among multiple time domain candidate resource groups within one S-SSB period relative to the starting position of the S-SSB period, where the number of time domain candidate resource groups within the S-SSB period is equal to the number of S-SSBs supported for transmission within the S-SSB period;

[0271] The second time domain resource indication information is used to indicate the time interval between every two groups of time domain candidate resources among multiple time domain candidate resource groups within the S-SSB period;

[0272] The third time domain resource indication information is used to indicate the number of time domain candidate resources in each time domain candidate resource group within the S-SSB period, where each time domain candidate resource group includes multiple consecutive time domain candidate resources, and the number of the multiple consecutive time domain candidate resources is less than the number of S-SSBs supported for transmission within the S-SSB period.

[0273] That is, in an embodiment of the present application, the network device configures N time domain candidate resource groups for the terminal device within one S-SSB period, and each time domain candidate resource group includes n consecutive time domain candidate resources, where N is the number of S-SSBs supported for transmission within one S-SSB period, 1 < n < N, N is a positive integer, and n is a positive integer. That is, the network device configures a total of N×n time domain candidate resources within the S-SSB period.

[0274] The time domain positions of these N×n time domain candidate resources can be determined by the first time domain resource indication information, the second time domain resource indication information, and the third time domain resource indication information.

[0275] In some embodiments, the first time domain resource indication information may be the parameter sl-timeoffsetssb multiplexed in the R16 direct link sidelink, or other newly defined parameters, and is used to indicate the offset of the first time domain candidate resource in the first time domain candidate resource group among these N time domain candidate resource groups within the S-SSB period relative to the starting position of the S-SSB period.

[0276] In some implementations, the second time-domain resource indication information may be the parameter sl-timeinterval from the R16 direct sidelink, or it may be other newly defined parameters, used to indicate the time interval between any two time-domain candidate resource groups among the N time-domain candidate resource groups within the S-SSB period, that is, the interval between the last time-domain candidate resource of the preceding time-domain candidate resource group and the first time-domain candidate resource of the following time-domain candidate resource group. Optionally, the unit of this time interval may be a time slot, or other granular units may be selected depending on the resource configuration.

[0277] The third time-domain resource indication information can indicate the number n of consecutive time-domain candidate resources in each time-domain candidate resource group within the S-SSB period. The third time-domain resource indication information can be a newly defined parameter.

[0278] Optionally, the value of n can be predefined by the network device, with the third time-domain resource indication information directly indicating the value of n, or it can be a value in a pre-configured set, where the third time-domain resource indication information can indicate an index in the set.

[0279] As an example, please see Figure 6 , Figure 6 This is a schematic diagram of a resource allocation method provided in an embodiment of this application. For example... Figure 6 As shown, the network device configures N time-domain candidate resource groups for the terminal device within one S-SSB cycle. The number of S-SSBs that can be sent within one S-SSB cycle is N. As an example, N=4. Each time-domain candidate resource group includes n consecutive time-domain candidate resources. As an example, n=3.

[0280] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource of the first time-domain resource group within the S-SSB cycle relative to the starting position of the S-SSB cycle.

[0281] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resource groups among the N time-domain candidate resources in the S-SSB period, that is, the interval between the last time-domain candidate resource of the previous time-domain candidate resource group and the first time-domain candidate resource of the next time-domain candidate resource group.

[0282] In some embodiments of this application, the frequency domain location of the plurality of time-domain candidate resources is on a specified LBT subband configured in the network device, or it may be on at least one frequency-domain candidate resource.

[0283] Step 503: Monitor the time-domain candidate resources in multiple time-domain candidate resource groups within the S-SSB period. The target resource is the first idle time-domain candidate resource in each group.

[0284] The target resource is the resource included among the multiple time-domain candidate resources used to send the S-SSB.

[0285] In this embodiment, the terminal device monitors the time-domain candidate resources in the plurality of time-domain candidate resource groups within the determined S-SSB period. It should be noted that, in this embodiment, the terminal device's monitoring of resources refers to performing LBT on the channel corresponding to the candidate resource.

[0286] For multiple consecutive time-domain candidate resources in each time-domain candidate resource group, in some implementations, the terminal device performs LBT on the first time-domain candidate resource in each time-domain candidate resource group, and does not perform LBT on the other time-domain candidate resources in the group.

[0287] In some implementations, the terminal device performs LBT on the first time-domain candidate resource of each time-domain candidate resource group, and LBT can also be performed on other time-domain candidate resources in the same group (such as Type2C LBT, etc.).

[0288] It should be noted that, in the embodiments of this application, each temporal candidate resource group is used to send the corresponding S-SSB.

[0289] In this embodiment, the first idle time-domain candidate resource detected in each time-domain candidate resource group, which is also the location of the first time-domain candidate resource where LBT (Local Time-Based Transmission) is successful, is used as the target resource. That is, the target resource for sending the S-SSB is the first idle time-domain candidate resource detected in each group. The terminal device can send the S-SSB corresponding to that time-domain candidate resource group on each idle time-domain candidate resource.

[0290] Step 504: Stop listening to the time-domain candidate resources that are located after the target resource in each time-domain candidate resource group.

[0291] In this embodiment of the application, after the terminal device detects an idle time-domain candidate resource in each time-domain candidate resource group, it will stop monitoring the remaining time-domain candidate resources in that time-domain candidate resource group.

[0292] Step 505: Send the S-SSB corresponding to each time domain candidate resource group on the target resource of each time domain candidate resource group.

[0293] In this embodiment, each time-domain candidate resource group is used to send the corresponding S-SSB. The terminal device is able to send the S-SSB corresponding to the time-domain candidate resource group on the first idle time-domain candidate resource it detects in each time-domain candidate resource group.

[0294] Step 506: Do not send the S-SSB corresponding to the busy time domain candidate resource group, wherein each time domain candidate resource in the busy time domain candidate resource group is busy.

[0295] In this embodiment of the application, if all time-domain candidate resources in a time-domain candidate resource group are busy, the time-domain candidate resource group is called a busy time-domain candidate resource group, and the terminal device does not send the S-SSB corresponding to the busy time-domain candidate resource group.

[0296] As an example, such as Figure 6 As shown, four time-domain candidate resource groups are configured for the terminal device within one S-SSB cycle, and the number of S-SSBs that can be sent within one S-SSB cycle is four. Each time-domain candidate resource group includes three consecutive time-domain candidate resources.

[0297] If all three time-domain candidate resources in the first time-domain candidate resource group are busy and LBT fails, the S-SSB corresponding to that time-domain candidate resource group (the first S-SSB within that S-SSB period) will not be sent. If the terminal device fails LBT at the first time-domain candidate resource (resource p21 in the diagram) in the second time-domain candidate resource group, but succeeds at the second time-domain candidate resource (resource p22 in the diagram), meaning that the first idle time-domain candidate resource in the second time-domain candidate resource group is the second time-domain candidate resource of that group, the terminal device will send the corresponding S-SSB (the second S-SSB within that S-SSB period) on that second time-domain candidate resource (resource p22 in the diagram). The terminal device successfully performs LBT at the first time-domain candidate resource position in the third time-domain candidate resource group. That is, the first idle time-domain candidate resource detected in the third time-domain candidate resource group is the first time-domain candidate resource of that group (resource p31 in the diagram). The terminal device then sends the corresponding S-SSB (the third S-SSB within the S-SSB cycle) on this first time-domain candidate resource (resource p31 in the diagram). Similarly, the terminal device successfully performs LBT at the third time-domain candidate resource position in the fourth time-domain candidate resource group (resource p43 in the diagram). That is, the first idle time-domain candidate resource detected in the fourth time-domain candidate resource group is the third time-domain candidate resource of that group. The terminal device then sends the corresponding S-SSB (the fourth S-SSB within the S-SSB cycle) on this third time-domain candidate resource (resource p43 in the diagram).

[0298] It is understood that, in the embodiments of this application, if each time-domain candidate resource group has an idle time-domain candidate resource detected, then all S-SSBs within the S-SSB period can be sent. If there is a busy time-domain candidate resource group, then only some S-SSBs can be sent within the S-SSB period, and the S-SSBs corresponding to the busy time-domain candidate resource group will not be sent.

[0299] In summary, by receiving resource configuration information sent by network devices, multiple time-domain candidate resources are identified based on this information. The system then monitors the time-domain candidate resources within multiple time-domain candidate resource groups during the S-SSB period. The target resource is the first idle time-domain candidate resource in each group. Monitoring of time-domain candidate resources following the target resource in each time-domain candidate resource group is stopped. The system then sends the corresponding S-SSB to the target resource in each time-domain candidate resource group, excluding S-SSBs for busy time-domain candidate resource groups. In the busy time-domain candidate resource group, all time-domain candidate resources are busy, enabling the terminal device to identify multiple time-domain candidate resources and send S-SSBs among them. This significantly and effectively improves the transmission success rate of S-SSBs for direct-link synchronization signals in unlicensed frequency bands, thereby improving system communication efficiency.

[0300] Please see Figure 7 , Figure 7 This is a flowchart illustrating a resource allocation method provided in an embodiment of this application. It should be noted that the resource allocation method in this embodiment is applied to unlicensed frequency bands and is executed by a terminal device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 7 As shown, the method may include the following steps:

[0301] Step 701: Receive resource configuration information sent by the network device.

[0302] In this embodiment, the resource configuration information includes time-domain resource indication information. The terminal device can determine multiple time-domain candidate resources by receiving the time-domain resource indication information.

[0303] Step 702: Based on the resource configuration information, determine multiple time-domain candidate resources.

[0304] In this embodiment of the application, the resource configuration information includes time-domain resource indication information, which includes: first time-domain resource indication information, second time-domain resource indication information, third time-domain resource indication information and fourth time-domain resource indication information.

[0305] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource in the first group of multiple time-domain candidate resource groups within an S-SSB period relative to the starting position of the S-SSB period.

[0306] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resource groups in the multiple time-domain candidate resource groups within the S-SSB period;

[0307] The third time-domain resource indication information is used to indicate the number of time-domain candidate resources in each time-domain candidate resource group within the S-SSB period. Each time-domain candidate resource group includes multiple consecutive time-domain candidate resources, and the number of these multiple time-domain candidate resources is equal to the number of S-SSBs that can be sent within the S-SSB period.

[0308] The fourth time-domain resource indication information is used to indicate the number of time-domain candidate resource groups within the S-SSB period.

[0309] In other words, in this embodiment of the application, the network device configures m time-domain candidate resource groups for the terminal device within one S-SSB cycle. Each time-domain candidate resource group includes N consecutive time-domain candidate resources, where N is the number of S-SSBs that can be transmitted within one S-SSB cycle, N is a positive integer, m>1, and m is a positive integer. That is, the network device configures a total of m×N time-domain candidate resources within this S-SSB cycle.

[0310] The temporal location of these m×N temporal candidate resources can be determined by the first temporal resource indication information, the second temporal resource indication information, the third temporal resource indication information, and the fourth temporal resource indication information.

[0311] In some implementations, the first time-domain resource indication information may be the parameter sl-timeoffsetssb in the R16 direct link sidelink, or it may be other newly defined parameters used to indicate the offset of the first time-domain candidate resource in the first time-domain candidate resource group among the m time-domain candidate resource groups in the S-SSB period relative to the starting position of the S-SSB period.

[0312] In some implementations, the second time-domain resource indication information may be the parameter sl-timeinterval from the R16 direct sidelink, or it may be other newly defined parameters, used to indicate the time interval between every two time-domain candidate resource groups among the m time-domain candidate resource groups within the S-SSB period, that is, the interval between the last time-domain candidate resource of the preceding time-domain candidate resource group and the first time-domain candidate resource of the following time-domain candidate resource group. Optionally, the unit of this time interval may be a time slot, or other granular units may be selected depending on the resource configuration.

[0313] The third time-domain resource indication information can indicate the number N of consecutive time-domain candidate resources in each time-domain candidate resource group within the S-SSB period. The third time-domain resource indication information can be a newly defined parameter.

[0314] In some implementations, since the number of consecutive time-domain candidate resources in each time-domain candidate resource group within the S-SSB period is the same as the number of S-SSBs that can be transmitted per S-SSB period, the time-domain resource indication information may not include the third time-domain resource indication information, and the terminal device can also determine the number of consecutive time-domain candidate resources in each group.

[0315] The fourth time-domain resource indication information can indicate the number m of time-domain candidate resource groups within the S-SSB period. This fourth time-domain resource indication information can be a newly defined parameter.

[0316] Optionally, the value of m can be predefined by the network device, with the fourth time-domain resource indication information directly indicating the value of m, or it can be a value in a pre-configured set, where the fourth time-domain resource indication information can indicate an index in the set.

[0317] As an example, please see Figure 8 , Figure 8 This is a schematic diagram of a resource allocation method provided in an embodiment of this application. For example... Figure 8 As shown, the network device configures m time-domain candidate resource groups for the terminal device within one S-SSB cycle. Each time-domain candidate resource group includes N consecutive time-domain candidate resources. The number of S-SSBs that can be sent within one S-SSB cycle is N. As an example, N=4.

[0318] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource of the first time-domain resource group within the S-SSB cycle relative to the starting position of the S-SSB cycle.

[0319] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resource groups among the m time-domain candidate resources in the S-SSB period, that is, the interval between the last time-domain candidate resource of the previous time-domain candidate resource group and the first time-domain candidate resource of the next time-domain candidate resource group.

[0320] In some embodiments of this application, the frequency domain location of the plurality of time-domain candidate resources may be on a specified LBT subband configured in the network device, or on at least one frequency-domain candidate resource.

[0321] Step 703: Monitor the time-domain candidate resources in multiple time-domain candidate resource groups within the S-SSB period. The target resource is the first time-domain candidate resource that is detected as idle in the multiple time-domain candidate resource groups, and the time-domain candidate resources that follow the first time-domain candidate resource that is detected as idle.

[0322] The target resource is the resource included among the multiple time-domain candidate resources used to send the S-SSB. The number of target resources (that is, the first time-domain candidate resource that is detected as idle, and the total number of time-domain candidate resources after the first time-domain candidate resource that is detected as idle) is equal to the number N of S-SSBs that can be sent within the S-SSB period.

[0323] In this embodiment, the terminal device monitors the time-domain candidate resources in the plurality of time-domain candidate resource groups within the determined S-SSB period. It should be noted that, in this embodiment, the terminal device's monitoring of resources refers to performing LBT on the channel corresponding to the candidate resource.

[0324] For multiple consecutive time-domain candidate resources in each time-domain candidate resource group, in some implementations, the terminal device performs LBT on the first time-domain candidate resource in each time-domain candidate resource group, and does not perform LBT on the other time-domain candidate resources in the group.

[0325] In some implementations, the terminal device performs LBT on the first time-domain candidate resource of each time-domain candidate resource group, and LBT can also be performed on other time-domain candidate resources in the same group (such as Type2C LBT, etc.).

[0326] It should be noted that, in the embodiments of this application, each temporal candidate resource group is used to send the corresponding S-SSB.

[0327] In an embodiment of the present application, the first time-domain candidate resource group that is monitored to be idle among multiple time-domain candidate resource groups, that is, the position of the first time-domain candidate resource that succeeds in LBT among multiple time-domain candidate resource groups, and the subsequent N - 1 time-domain candidate resources of the first time-domain candidate resource that is monitored to be idle are used as target resources for transmitting S-SSB. The terminal device can transmit S-SSB on the target resources.

[0328] Step 704: The first time-domain candidate resource that is monitored to be idle is the nth time-domain candidate resource in the first time-domain candidate resource group. On the nth time-domain candidate resource in the first time-domain candidate resource group and the subsequent N - n time-domain candidate resources in the first time-domain candidate resource group, continuously transmit N - n + 1 S-SSBs within the S-SSB period.

[0329] Among them, 1 < n < N, n is a positive integer, and N is the number of S-SSBs supported for transmission within the S-SSB period.

[0330] In an embodiment of the present application, if the first time-domain candidate resource that the terminal device monitors to be idle is the nth time-domain candidate resource in the first time-domain candidate resource group, the terminal device will continuously transmit N - n + 1 S-SSBs within the S-SSB period on the nth time-domain candidate resource in the first time-domain candidate resource group and the subsequent N - n time-domain candidate resources in the first time-domain candidate resource group.

[0331] That is, among the multiple time-domain candidate resource groups, if the first time-domain candidate resource that the terminal device monitors to be idle is the nth time-domain candidate resource in the first time-domain candidate resource group, the terminal device will start from the nth time-domain candidate resource in the first time-domain candidate resource group and continuously transmit N - n + 1 S-SSBs within the S-SSB period.

[0332] It can be understood that in some embodiments, if the first time-domain candidate resource that the terminal device monitors to be idle is the first time-domain candidate resource in the first time-domain candidate resource group, then in the first time-domain candidate resource group, the terminal device can continuously transmit all N S-SSBs within the S-SSB period. The terminal device can stop monitoring the time-domain candidate resources in the remaining time-domain candidate resource groups.

[0333] It should be noted that in an embodiment of the present application, the first time-domain resource group is not necessarily the first one among the multiple time-domain resource groups.

[0334] In some implementations, among the N-n+1 consecutive time-domain candidate resources (the nth time-domain candidate resource in the first time-domain candidate resource group, and the Nn time-domain candidate resources following the nth time-domain candidate resource in the first time-domain candidate resource group), the terminal device may not perform LBT on the subsequent Nn time-domain candidate resources.

[0335] In some implementations, among the N-n+1 consecutive time-domain candidate resources (the nth time-domain candidate resource in the first time-domain candidate resource group, and the Nn time-domain candidate resources following the nth time-domain candidate resource in the first time-domain candidate resource group), the terminal device can perform LBT (such as Type2C LBT, etc.) on the subsequent Nn time-domain candidate resources.

[0336] Step 705: On idle time-domain candidate resources detected in subsequent time-domain candidate resource groups, continuously send the remaining n-1 S-SSBs within the S-SSB period.

[0337] In this embodiment of the application, after the terminal device sends N-n+1 S-SSBs within the S-SSB period in the first time-domain candidate resource group, it can monitor the time-domain candidate resources in subsequent time-domain candidate resource groups of the first time-domain candidate resource group.

[0338] The terminal device can listen for idle time-domain candidate resources in subsequent time-domain candidate resource groups and continuously send the remaining n-1 S-SSBs within the S-SSB period.

[0339] Step 706: After sending the N S-SSBs, stop listening to the remaining time-domain candidate resources in the time-domain candidate resource group.

[0340] After sending the N S-SSBs, the terminal device can stop listening to the remaining time-domain candidate resources in the time-domain candidate resource group.

[0341] As an example, such as Figure 8 As shown, the network device configures m time-domain candidate resource groups for the terminal device within one S-SSB cycle. Each time-domain candidate resource group includes 4 consecutive time-domain candidate resources. The number of S-SSBs that can be sent within one S-SSB cycle is 4.

[0342] If the terminal device fails to perform LBT at the first candidate resource (resource p11 in the diagram) in the first time-domain candidate resource group, but succeeds at the second time-domain candidate resource (resource p12 in the diagram), then the first idle time-domain candidate resource detected by the terminal device is the second time-domain candidate resource in the first time-domain candidate resource group. The terminal device consecutively sends three S-SSBs at the second time-domain candidate resource (resource p12 in the diagram), the third time-domain candidate resource (resource p13 in the diagram), and the fourth time-domain candidate resource (resource p14 in the diagram) in the first time-domain candidate resource group. Then, if the LBT at the first candidate resource (resource p21 in the diagram) in the second time-domain candidate resource group succeeds, the terminal device will send the remaining S-SSB within the S-SSB period at the first time-domain candidate resource (resource p21 in the diagram) in the second time-domain candidate resource group. The terminal device sends a total of four S-SSBs. LBT will not be performed at the remaining time-domain candidate resource, and that time-domain candidate resource will not be used.

[0343] It is understandable that if the terminal device does not send all remaining S-SSBs in the second time domain candidate resource group, the terminal device will continue to listen to the time domain candidate resources in subsequent time domain candidate resource groups.

[0344] In summary, by receiving resource configuration information sent by network devices, multiple time-domain candidate resources are determined based on this information. The time-domain candidate resources in multiple time-domain candidate resource groups within the S-SSB period are monitored. The first idle time-domain candidate resource detected is the nth time-domain candidate resource in the first time-domain candidate resource group. The S-SSB period is then continuously transmitted on the nth time-domain candidate resource in the first time-domain candidate resource group, and on the Nn time-domain candidate resources following the nth time-domain candidate resource in the first time-domain candidate resource group. Within the N-n+1 S-SSBs, when an idle time-domain candidate resource is detected in the subsequent time-domain candidate resource group, the remaining n-1 S-SSBs within the S-SSB period are continuously transmitted. After transmitting the N S-SSBs, the listening for time-domain candidate resources in the remaining time-domain candidate resource group is stopped. This allows the terminal device to identify multiple time-domain candidate resources and transmit S-SSBs in these multiple time-domain candidate resources. This can significantly and effectively improve the transmission success rate of S-SSBs for direct link synchronization signals in unlicensed frequency bands and improve system communication efficiency.

[0345] Please see Figure 9 , Figure 9 This is a flowchart illustrating a resource allocation method provided in an embodiment of this application. It should be noted that the resource allocation method in this embodiment is applied to unlicensed frequency bands and is executed by a terminal device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 9As shown, the method may include the following steps:

[0346] Step 901: Receive resource configuration information sent by the network device.

[0347] In this embodiment, the resource configuration information includes frequency domain resource indication information. The terminal device can determine at least one candidate frequency domain resource by receiving this frequency domain resource indication information.

[0348] Step 902: Based on the resource configuration information, determine at least one frequency domain candidate resource.

[0349] In this embodiment of the application, the resource configuration information includes frequency domain resource indication information, which includes: first frequency domain resource indication information and second frequency domain resource indication information.

[0350] The first frequency domain resource indication information is used to indicate the frequency interval between each frequency domain candidate resource and the specified frequency domain resource in the at least one frequency domain candidate resource. Optionally, the unit of the frequency interval can be 20MHz, or other granularity units can be selected according to different resource configurations.

[0351] The second time-domain resource indication information is used to indicate the number of candidate resources in the frequency domain.

[0352] The specified frequency domain resources are configured by the network equipment, and the terminal equipment performs S-SSB transmission on the LBT subband of the specified sequence number.

[0353] In other words, in this embodiment of the application, the network device can configure M frequency domain candidate resources for the terminal device, where M is a positive integer. The frequency domain positions of these M frequency domain candidate resources can be determined by the first frequency domain resource indication information and the second frequency domain resource indication information.

[0354] In some implementations, the first frequency domain resource indication information can be other newly defined parameters used to indicate the frequency interval between each of the M frequency domain candidate resources and the specified frequency domain resource. Optionally, the unit of the frequency interval can be 20MHz, or other granularity units can be selected depending on the resource configuration.

[0355] In some implementations, the second time-domain resource indication information may be other newly defined parameters used to indicate the number M of the frequency-domain candidate resources.

[0356] Optionally, the value of M can be predefined by the network device, with the second frequency domain resource indication information directly indicating the value of M, or it can be a value in a pre-configured set, where the second frequency domain resource indication information can indicate an index in the set.

[0357] Step 903: Monitor the specified frequency domain resources.

[0358] In this embodiment, the terminal device is capable of monitoring designated reputation resources. It should be noted that, in this embodiment, monitoring resources by the terminal device refers to performing LBT (Local Bit Bypass) on the channel corresponding to the candidate resource.

[0359] In the embodiments of this application, the configuration of time domain resources in the specified frequency domain resources can adopt the time domain candidate resource configuration method in any embodiment of this application, or other configuration methods, such as fixed time domain resource configuration, etc., which are not limited here.

[0360] Step 904: If the specified frequency domain resource is found to be busy, listen to at least one frequency domain candidate resource, with the target resource being the frequency domain candidate resource that is found to be free.

[0361] The target resource is the resource included in the at least one frequency domain candidate resource for transmitting the S-SSB.

[0362] In this embodiment of the application, if the terminal device detects that the specified frequency domain resource is busy and LBT fails, the terminal device will monitor the at least one frequency domain candidate resource.

[0363] If LBT is successful on a frequency domain candidate resource, the terminal device can send the S-SSB on the idle frequency domain candidate resource it has detected.

[0364] In the embodiments of this application, the configuration of time-domain resources in the at least one frequency-domain candidate resource can adopt the time-domain candidate resource configuration method in any embodiment of this application, or other configuration methods, such as fixed time-domain resource configuration, etc., which are not limited here.

[0365] As an example, the terminal device sends an S-SSB on the LBT subband with sequence number 0. The network device configures two candidate LBT subbands for the terminal device, with sequence numbers 1 and 2. If the LBT fails on the LBT subband with sequence number 0, the terminal device can perform LBT on the LBT subbands with sequence numbers 1 and 2. If the LBT succeeds, the terminal device can send the S-SSB on the successful LBT subband.

[0366] In summary, by receiving resource configuration information sent by network devices, at least one frequency domain candidate resource is identified based on this information. The specified frequency domain resource is monitored. If the specified frequency domain resource is found to be busy, at least one frequency domain candidate resource is monitored. The target resource is the frequency domain candidate resource that is found to be idle. This enables the terminal device to identify multiple time domain candidate resources and send S-SSBs among these multiple time domain candidate resources. This can significantly and effectively improve the transmission success rate of S-SSBs for direct links in unlicensed frequency bands and improve system communication efficiency.

[0367] Please see Figure 10 , Figure 10 This is a flowchart illustrating a resource allocation method provided in an embodiment of this application. It should be noted that the resource allocation method in this embodiment is applied to unlicensed frequency bands and is executed by a network device. This method can be executed independently or in conjunction with any other embodiment of this application. Figure 10 As shown, the method may include the following steps:

[0368] Step 1001: Send resource configuration information to the terminal device. The resource configuration information is used to determine multiple time-domain candidate resources and / or at least one frequency-domain candidate resource. The multiple time-domain candidate resources and / or at least one frequency-domain candidate resource are used to send the direct link synchronization signal block S-SSB.

[0369] In one embodiment of the application, the network device can send resource configuration information to the terminal device, which is used to determine multiple candidate resources. These multiple candidate resources are used to send the Direct Link Synchronization Signal Block (S-SSB).

[0370] In some implementations, the resource configuration information includes at least one of time-domain resource indication information and frequency-domain configuration information.

[0371] Among them, the time-domain resource indication information is used to determine multiple time-domain candidate resources, and the frequency-domain resource indication information is used to determine at least one frequency-domain candidate resource.

[0372] In other words, as a first possible implementation, the resource configuration information includes time-domain resource indication information, and the terminal device can determine multiple time-domain candidate resources based on the resource configuration information.

[0373] As a second possible implementation, the resource configuration information includes frequency domain resource indication information, and the terminal device can determine at least one frequency domain candidate resource based on the resource configuration information.

[0374] As a third possible implementation, the resource configuration information includes time-domain resource indication information and frequency-domain configuration information. The terminal device can determine multiple time-domain candidate resources and at least one frequency-domain candidate resource based on the resource configuration information.

[0375] In some implementations, the plurality of candidate resources includes a target resource, on which the terminal device sends an S-SSB.

[0376] Optionally, in the embodiments of this application, the frequency domain location of the plurality of time-domain candidate resources may be on a designated LBT sub-band configured in the network device, or on at least one frequency-domain candidate resource, wherein the designated LBT sub-band has a different frequency from the at least one frequency-domain candidate resource.

[0377] In some implementations, the time-domain resource indication information includes: first time-domain resource indication information, second time-domain resource indication information, and third time-domain resource indication information.

[0378] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource relative to the start position of the S-SSB cycle among multiple time-domain candidate resources in an S-SSB cycle.

[0379] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resources among multiple time-domain candidate resources in the S-SSB period;

[0380] The third time-domain resource indication information is used to indicate the number of time-domain candidate resources in the S-SSB period, wherein the number of time-domain candidate resources in the S-SSB period is greater than the number of S-SSBs that can be transmitted in the S-SSB period.

[0381] In some implementations, the time-domain resource indication information includes: first time-domain resource indication information, second time-domain resource indication information, and third time-domain resource indication information.

[0382] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource in the first group of multiple time-domain candidate resource groups in an S-SSB period relative to the start position of the S-SSB period. The number of time-domain candidate resource groups in the S-SSB period is equal to the number of S-SSBs that can be transmitted in the S-SSB period.

[0383] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resource groups in the multiple time-domain candidate resource groups within the S-SSB period;

[0384] The third time-domain resource indication information is used to indicate the number of time-domain candidate resources in each time-domain candidate resource group within the S-SSB period. Each time-domain candidate resource group includes multiple consecutive time-domain candidate resources, and the number of these multiple time-domain candidate resources is less than the number of S-SSBs that can be sent within the S-SSB period.

[0385] In some implementations, the time-domain resource indication information includes: first time-domain resource indication information, second time-domain resource indication information, third time-domain resource indication information, and fourth time-domain resource indication information.

[0386] The first time-domain resource indication information is used to indicate the offset of the first time-domain candidate resource in the first group of multiple time-domain candidate resource groups within an S-SSB period relative to the starting position of the S-SSB period.

[0387] The second time-domain resource indication information is used to indicate the time interval between every two time-domain candidate resource groups in the multiple time-domain candidate resource groups within the S-SSB period;

[0388] The third time-domain resource indication information is used to indicate the number of time-domain candidate resources in each time-domain candidate resource group within the S-SSB period. Each time-domain candidate resource group includes multiple consecutive time-domain candidate resources, and the number of these multiple time-domain candidate resources is equal to the number of S-SSBs that can be sent within the S-SSB period.

[0389] The fourth time-domain resource indication information is used to indicate the number of time-domain candidate resource groups within the S-SSB period.

[0390] In some implementations, the frequency domain resource indication information includes: first frequency domain resource indication information and second frequency domain resource indication information.

[0391] The first frequency domain resource indication information is used to indicate the frequency interval between each frequency domain candidate resource and the specified frequency domain resource in the at least one frequency domain candidate resource.

[0392] The second time-domain resource indication information is used to indicate the number of candidate resources in the frequency domain.

[0393] In summary, by sending resource configuration information to the terminal device, which is used to determine multiple time-domain candidate resources and / or at least one frequency-domain candidate resource, and these multiple time-domain candidate resources and / or at least one frequency-domain candidate resource are used to transmit the direct link synchronization signal block S-SSB, the terminal device can determine multiple time-domain candidate resources and transmit the S-SSB from among these multiple time-domain candidate resources. This can significantly and effectively improve the transmission success rate of the direct link synchronization signal block S-SSB in the unlicensed frequency band and improve the system communication efficiency.

[0394] Corresponding to the resource configuration methods provided in the above embodiments, this application also provides a resource configuration device. Since the resource configuration device provided in this application corresponds to the methods provided in the above embodiments, the implementation of the resource configuration method is also applicable to the resource configuration device provided in the following embodiments, which will not be described in detail in the following embodiments.

[0395] Please see Figure 11 , Figure 11 This is a schematic diagram of the structure of a resource allocation device provided in an embodiment of this application.

[0396] like Figure 11 As shown, the resource allocation device 1100 is applied to an unlicensed frequency band and includes: a transceiver unit 1110 and a processing unit 1120, wherein:

[0397] The transceiver unit 1110 is used to receive resource configuration information sent by network devices;

[0398] The processing unit 1120 is configured to determine multiple time-domain candidate resources and / or at least one frequency-domain candidate resource based on the resource configuration information.

[0399] The plurality of time-domain candidate resources and / or at least one frequency-domain candidate resource are used to transmit the direct link synchronization signal block S-SSB.

[0400] Optionally, the processing unit 1120 is specifically used for:

[0401] Based on the time-domain resource indication information in the resource configuration information, the multiple time-domain candidate resources are determined.
