[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0045] First, some terms used in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0046] 1) Sidelink (SL)

[0047] Sidelinks, also known as edge links or side links, are used for communication between terminals, including one-to-one and one-to-many sidelink communication. One-to-one sidelink communication may include unicast, while one-to-many sidelink communication includes broadcast and multicast. For example, broadcast may refer to communication with all terminals within a cell, while multicast may refer to communication with terminals in a communication group, which includes one or more terminals. Sidelink communication may include direct communication between two terminals or sidelink communication forwarded by a relay node.

[0048] 2) PC-5 air interface

[0049] The PC-5 air interface is an interface used for wireless communication between terminals, meaning that one terminal communicates with another terminal through the PC-5 air interface.

[0050] 3) Sidelink resources

[0051] Resources for transmitting sidelink services between two terminal devices on the sidelink.

[0052] 4) Resource Pool

[0053] The resource pool is a collection of resources consisting of time-domain resources (composed of several side-row subframes) and frequency-domain resources (composed of several subchannels, and a subchannel consists of several consecutive RBs), used for SL transmission between two terminals.

[0054] 5) Time Unit: Time-domain resources include one or more time units, which can be radio frames, subframes, time slots, symbols, etc. A radio frame can include multiple subframes, a subframe can include one or more time slots, and a time slot can include at least one symbol. Alternatively, a radio frame can include multiple time slots, and a time slot can include at least one symbol.

[0055] 6) Unlicensed spectrum (unlicensed frequency bands)

[0056] Unlicensed spectrum is spectrum allocated by a country or region for use in wireless communication. This spectrum is usually considered a shared spectrum, meaning that communication equipment in different communication systems can use the spectrum as long as it meets the regulatory requirements set by the country or region on that spectrum, without needing to apply for a proprietary spectrum license from the government.

[0057] To ensure the harmonious coexistence of various communication systems using unlicensed spectrum, some countries or regions have stipulated regulatory requirements for the use of unlicensed spectrum. For example, communication devices must adhere to the "listen before talk" (LBT) principle. This means that before transmitting signals on an unlicensed spectrum channel, the communication device must first perform channel listening. Only when the channel listening result indicates that the channel is idle can the communication device transmit signals; if the channel listening result indicates that the channel is busy, the communication device cannot transmit signals.

[0058] 7) Resource allocation mode

[0059] Resource configuration mode is also called resource allocation mode. A terminal can use one or two resource configuration modes.

[0060] The first resource allocation mode is that the resources for each data transmission by the terminal on the side link are scheduled and allocated by the network-side device.

[0061] The second resource allocation mode involves the terminal dynamically selecting resources from a configured resource pool each time it transmits data on the sidelink. This resource pool can be configured by the network-side device via system broadcast messages or RRC messages. When sending data, the terminal can autonomously obtain at least a portion of the resources from the resource pool through random selection, a listener reservation mechanism, or a partial listener reservation mechanism.

[0062] In related technologies, the Sidelink communication method is introduced to support direct communication between terminals, where the interface between terminals is PC-5. As described above, the Sidelink communication method currently has two resource allocation methods: one is dynamic network scheduling (the first resource allocation mode), and the other is terminal-based selection from a network broadcast resource pool (the second resource allocation mode). The second resource allocation mode, because terminals autonomously select resources, may result in different terminals selecting the same resource to send data, leading to transmission collisions. Unlike the second resource allocation mode, the first resource allocation mode prevents adjacent terminals from being allocated the same resource, ensuring better transmission reliability.

[0063] To expand available frequencies, terminals can perform Sidelink transmissions (SidelinkUnlicense, Sidelink-U) on unlicensed frequency bands. When a terminal device performs Sidelink transmissions on an unlicensed frequency band, it needs to perform an idle channel assessment operation, which may include an LBT (Local Lightning Detection) mechanism. Through the LBT mechanism, network-side devices can avoid interference while ensuring fairness among different terminals.

[0064] Typically, a terminal can only use unlicensed frequency bands for sidelink transmission after a successful LBT (Local Level Transmission). However, in dynamically scheduled transmission resource allocation methods, the network-side equipment that allocates unlicensed frequency bands to the terminal may not have the capability to perform LBTs on those unlicensed frequency bands. This would prevent the terminal from performing sidelink transmissions on the allocated unlicensed frequency band resources, leading to data transmission failures or delays.

[0065] To address the aforementioned problems, this disclosure provides an auxiliary information reporting method, apparatus, storage medium, terminal, and network-side device. The implementation environment of this disclosure embodiment is described below.

[0066] Please see Figure 1 , Figure 1 This illustrates an application scenario for an auxiliary information reporting method, based on some embodiments. For ease of explanation, only the parts relevant to this embodiment are shown.

[0067] like Figure 1As shown, this application scenario includes a first terminal 11, a second terminal 12, and a network-side device 13. The first terminal 11 and the second terminal 12 can communicate with each other via a PC5 interface using Sidelink. The network-side device 13 can communicate with the terminals (including the first terminal 11 and the second terminal 12) via an air interface using uplink and downlink.

[0068] The first terminal 11 and the second terminal 12 are user terminals (UEs) or other terminal-side devices, such as mobile phones, tablet personal computers, laptop computers, personal digital assistants (PDAs), mobile internet devices (MIDs), wearable devices, smart cars, in-vehicle devices, or robots. It is worth noting that this disclosure does not limit the specific type of terminal.

[0069] Network-side device 13 can be a base station, which is a device deployed in an access network to provide wireless communication functions for terminals. This base station can be a base station of the terminal's serving cell or a base station of a neighboring cell. Base stations can include various forms of macro base stations, micro base stations, relay stations, access points, transmission and reception points (TRPs), etc. In systems employing different wireless access technologies, the name of the device with base station functionality may differ; in 5G New Radio (NR) systems, it is called gNodeB or gNB. As communication technologies evolve, the term "base station" may change in meaning.

[0070] It is worth noting that, in Figure 1 In the network system shown, the first terminal 11 and the second terminal 12 communicate via a direct Sidelink link. In other embodiments, the first terminal 11 and the second terminal 12 may also communicate via an indirect Sidelink link. That is, the first terminal 11 and the second terminal 12 communicate through at least one relay terminal.

[0071] Figure 2 This is a flowchart illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 2 As shown, this auxiliary information reporting method can be used in the first terminal and includes the following steps.

[0072] In step 201, the first terminal determines that there is channel occupancy time on the unlicensed resources.

[0073] As one possible implementation, when the first terminal accesses a channel in an unlicensed frequency band, it can determine whether it can access the channel based on the Channel Access Priority Class (CAPC). Specifically, the first terminal can perform channel monitoring. If it determines that the channel is idle for a certain period of time, the first terminal determines that it can perform Sidelink transmission (transmission in Sidelink-U) in the unlicensed frequency band. During this process, the transmission time of the first terminal can be called the Channel Occupancy Time (COT). The Channel Occupancy Time (COT) can be the Sidelink Channel Occupancy Time. Alternatively, in this embodiment, the Channel Occupancy Time can be the Sidelink Channel Occupancy Time.

[0074] As described above, when terminals schedule resources on unlicensed frequency bands, they can achieve resource scheduling through network dynamic scheduling. However, scheduling resources on unlicensed frequency bands typically requires Level-by-Browser (LBT). In other words, network-side devices need to perform LBT before transmitting signals when scheduling resources on unlicensed frequency bands. However, existing network-side devices cannot perform LBT on Sidelink, which can lead to data transmission failures or delays.

[0075] To address the aforementioned issues, this application allows LBT to be performed via a terminal, meaning the terminal possesses the capability to perform LBT on the Sidelink. Specifically, the terminal can detect whether Channel Occupied Time (COT) exists on unlicensed resources. If the first terminal determines that COT exists on unlicensed resources, it can send auxiliary information related to COT to the network-side device, proceeding to step S202.

[0076] As one possible implementation, if the first terminal determines that there is no channel occupancy time on the unlicensed resources, the first terminal can send a first indication message to the network-side device to indicate that the unlicensed resources are unavailable, thereby requesting the network-side device to reconfigure the unlicensed resources.

[0077] In this embodiment, unlicensed resources may include unlicensed frequencies or sidelink resources on unlicensed frequencies. In other words, unlicensed resources may be unlicensed frequencies (e.g., unlicensed frequencies ranging from 900MHz to 950MHz), sidelink resources on unlicensed frequencies, or sidelink resources on both unlicensed and unlicensed frequencies.

[0078] As another possible implementation, sidelink resources on unlicensed frequencies may include at least one of a sidelink resource pool, a time-domain location of the resource, and a frequency-domain location of the resource. The sidelink resource pool may be a sidelink transmission resource pool. For example, sidelink resources on unlicensed frequencies may include resource pool 1.

[0079] Furthermore, the temporal and frequency domain locations of resources can be the temporal and frequency domain locations of sidelink resources, respectively. The temporal location can be determined by the network-side device using at least one of period, subframe, or duration. The frequency domain location can be determined by the network-side device using at least one of subband, frequency, or PRB (Physical Resource Block) location.

[0080] In step 202, the first terminal sends auxiliary information related to channel occupancy time to the network-side device.

[0081] As one possible implementation, after determining that there is channel occupancy time on unlicensed resources, the first terminal can send auxiliary information related to the channel occupancy time to the network-side device. In other words, the first terminal can send auxiliary information related to the channel occupancy time to the network-side device.

[0082] As one possible implementation, the auxiliary information may include at least one of the following: the unlicensed frequency identifier where the channel occupancy time is located, the Sidelink resource pool identifier where the channel occupancy time is located, the start time of the channel occupancy time, the end time of the channel occupancy time, the duration of the channel occupancy time, the channel access priority (CAPC) allowed for access during the channel occupancy time, and the allowed transmission methods during the channel occupancy time. As to which one or more of the above information are specifically included in the auxiliary information, no explicit limitation is made here, and the selection can be made according to the actual situation.

[0083] As an example, auxiliary information may include the unlicensed frequency identifier where the channel occupancy time is located, the Sidelink resource pool identifier where the channel occupancy time is located, the start time of the channel occupancy time, the duration of the channel occupancy time, the channel access priority (CAPC) allowed to be accessed during the channel occupancy time, and the transmission methods allowed during the channel occupancy time.

[0084] As another example, auxiliary information may include the unlicensed frequency identifier where the channel occupancy time is located, the start time of the channel occupancy time, the end time of the channel occupancy time, the channel access priority (CAPC) allowed to be accessed during the channel occupancy time, and the transmission methods allowed during the channel occupancy time.

[0085] As one possible implementation, the transmission method for channel occupancy time can include at least one of Sidelink discovery and Sidelink communication. Sidelink discovery refers to a method used to determine / establish the proximity of two or more Sidelink terminals (e.g., within the range for direct Sidelink communication) or to determine / establish the proximity of a first terminal to a second terminal. Sidelink discovery can be divided into open Sidelink discovery and restricted Sidelink discovery. Sidelink communication refers to a method where some or all communication data between Sidelink terminals can be communicated directly without going through network infrastructure. Sidelink communication can include unicast, multicast, or broadcast; that is, Sidelink communication can be divided into Sidelink broadcast communication, Sidelink multicast communication, and Sidelink unicast communication.

[0086] Unicast refers to communication between one terminal and another terminal; multicast refers to communication between one terminal and a group of terminals. Here, a group of terminals can refer to terminals within a certain geographical range, a group of terminals with fixed communication, or a group of terminals with a certain purpose for communication, etc.; broadcast refers to communication between one terminal and an unspecified number of terminals. Here, the unspecified number of terminals can refer to all terminals in a cell, and all terminals can include one or more groups of terminals.

[0087] As one possible implementation, the first terminal sends auxiliary information related to the channel occupancy time to the network-side device to instruct the network-side device to schedule resources during the channel occupancy time. In this embodiment, the first terminal can report the detected channel occupancy time (idle resource location) to the network-side device, which enables the first terminal to perform sidelink transmission on scheduled unlicensed resources, thereby ensuring the success of data transmission or reducing data transmission latency.

[0088] Figure 3 This is a flowchart illustrating an auxiliary information reporting method according to some other embodiments. For example... Figure 3 As shown, this auxiliary information reporting method can be used in the first terminal and includes the following steps.

[0089] In step 301, the first terminal receives unauthorized resources configured by the network-side device.

[0090] In this embodiment, the first terminal can receive unlicensed resources configured by the network-side device. Similar to the embodiments described above, the unlicensed resources in this embodiment may also include unlicensed frequencies or sidelink resources on unlicensed frequencies. In other words, unlicensed resources can be unlicensed frequencies, sidelink resources on unlicensed frequencies, or both unlicensed frequencies and sidelink resources on unlicensed frequencies.

[0091] As another possible implementation, the Sidelink resources on unlicensed frequencies may include at least one of a Sidelink resource pool, a time-domain location of the resource, and a frequency-domain location of the resource. The Sidelink resource pool may be a Sidelink transmission resource pool.

[0092] Furthermore, the time-domain location and frequency-domain location of a resource can be the time-domain location and frequency-domain location of a Sidelink resource, respectively. The time-domain location can be determined by the network-side device using at least one of period, subframe, or duration; this time-domain location can also be referred to as the temporal location. The frequency-domain location can be determined by the network-side device using at least one of subband, frequency, or PRB location.

[0093] In step 302, the first terminal determines that there is channel occupancy time on the unlicensed resources configured by the network-side device.

[0094] As one possible implementation, after receiving the unlicensed resource configured by the network-side device, the first terminal can determine whether there is a channel occupancy time on the unlicensed resource configured by the network-side device. If the first terminal determines that there is a channel occupancy time on the unlicensed resource configured by the network-side device, it can send auxiliary information related to the channel occupancy time to the network-side device.

[0095] As another possible implementation, if the first terminal determines that there is no channel occupancy time on the unlicensed resources, the first terminal can send a first indication message to the network-side device to indicate that the unlicensed resources are unavailable, that is, to request the network-side device to reconfigure the unlicensed resources.

[0096] As an example, if the time domain location of the unauthorized resources configured on the network side device is 4:00-5:00, and the first terminal determines that there is a channel occupancy time between 4:00-5:00 through detection, then the first terminal can send the auxiliary information corresponding to 4:00-5:00 to the network side device.

[0097] As another example, if the time domain location of the unlicensed resources configured by the network-side device is 5:00-5:30, and the first terminal determines by detection that there is no channel occupancy time between 5:00-5:30, then the first terminal can send a first indication information to the network-side device to indicate that there is no channel occupancy time between 5:00-5:30, and request the network-side device to configure new unlicensed resources, that is, request to reconfigure unlicensed resources.

[0098] In step 303, the first terminal sends auxiliary information related to channel occupancy time to the network-side device.

[0099] As one possible implementation, after the first terminal determines that there is channel occupancy time on the unlicensed resources configured by the network-side device, it can send auxiliary information related to the channel occupancy time to the network-side device. In this embodiment, the auxiliary information may include at least one of the following: the unlicensed frequency identifier where the channel occupancy time is located, the Sidelink resource pool identifier where the channel occupancy time is located, the start time of the channel occupancy time, the end time of the channel occupancy time, the duration of the channel occupancy time, the channel access priority (CAPC) allowed for access during the channel occupancy time, and the transmission methods allowed during the channel occupancy time.

[0100] In this embodiment, the first terminal can determine the channel occupancy time based on the unlicensed resources configured by the network-side device, and can accurately and effectively send the auxiliary information it has acquired to the network-side device, thereby ensuring the success of data transmission or reducing the latency of data transmission.

[0101] Figure 4 This is a flowchart illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 4 As shown, this auxiliary information reporting method can be used in the first terminal and includes the following steps.

[0102] In step 401, the first terminal receives unauthorized resources sent by the network-side device via an RRC reconfiguration message.

[0103] As one possible implementation, unlicensed resources can be sent to the first terminal by the network-side device via an RRC (Radio Resource Control) reconfiguration message. In this process, the first terminal can first receive the RRC reconfiguration message and then obtain the unlicensed resources from it. These unlicensed resources can be resources configured by the network-side device. Additionally, unlicensed resources can also include unlicensed frequencies or sidelink resources on unlicensed frequencies. Specifically, sidelink resources on unlicensed frequencies can include at least one of a sidelink resource pool, a time-domain location of the resource, and a frequency-domain location of the resource.

[0104] In step 402, the first terminal determines that there is channel occupancy time on the unlicensed resources configured by the network-side device.

[0105] In step 403, the first terminal sends auxiliary information related to channel occupancy time to the network-side device.

[0106] The implementation methods for steps 402 to 403 can refer to the above-mentioned related embodiments, and will not be repeated here.

[0107] In this embodiment, the unauthorized resources received by the first terminal can be sent by the network-side device via an RRC reconfiguration message, which improves the real-time performance of unauthorized resource acquisition. Furthermore, this application also enables the first terminal to perform sidelink transmission on scheduled unauthorized resources, thereby improving the data transmission success rate or reducing data transmission latency.

[0108] Figure 5 This is a flowchart illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 5 As shown, this auxiliary information reporting method can be used in the first terminal and includes the following steps.

[0109] In step 501, the first terminal receives the channel occupancy time on the unlicensed resources shared by the second terminal.

[0110] In this embodiment, the first terminal can receive the channel occupancy time on the unlicensed resources shared by the second terminal; that is, the first terminal can receive the channel occupancy time obtained by the second terminal. The channel occupancy time on the unlicensed resources shared by the second terminal can be determined by the second terminal based on the unlicensed resources configured by the network-side equipment.

[0111] Furthermore, the channel occupancy time on unlicensed resources shared by the second terminal can also be sent to the second terminal by another terminal, and then sent to the first terminal by the second terminal. For example, the channel occupancy time on unlicensed resources shared by the second terminal can be shared by a third terminal. The specific method for obtaining the channel occupancy time on unlicensed resources shared by the second terminal is not explicitly limited here and can be chosen based on the actual situation.

[0112] As one possible implementation, the channel occupancy time on the unlicensed resources received by the first terminal can be the same as the channel occupancy time on the unlicensed resources received by the second terminal. For example, if the second terminal determines that the acquired channel occupancy time is 4:00-5:00, the channel occupancy time on the unlicensed resources received by the first terminal can also be 4:00-5:00.

[0113] As another possible implementation, the channel occupancy time on the unlicensed resources received by the first terminal may differ from the channel occupancy time on the unlicensed resources determined by the second terminal. For example, if the second terminal determines that the acquired channel occupancy time is 4:00-5:00, the channel occupancy time on the unlicensed resources shared by the second terminal received by the first terminal may be 4:30-5:00.

[0114] It is evident that the channel occupancy time on unlicensed resources received by the first terminal may be the same as or different from the channel occupancy time on unlicensed resources determined by the second terminal, which is mainly determined by the second terminal.

[0115] In this embodiment, unlicensed resources may also include unlicensed frequencies or sidelink resources on unlicensed frequencies. In other words, unlicensed resources can be unlicensed frequencies, sidelink resources on unlicensed frequencies, or both.

[0116] As another possible implementation, the Sidelink resources on unlicensed frequencies may include at least one of a Sidelink resource pool, a time-domain location of the resource, and a frequency-domain location of the resource. The Sidelink resource pool may be a Sidelink transmission resource pool.

[0117] Furthermore, the time-domain location and frequency-domain location of a resource can be the time-domain location and frequency-domain location of a Sidelink resource, respectively. The time-domain location can be determined by the network-side device using at least one of period, subframe, or duration. The frequency-domain location can be determined by the network-side device using at least one of subband, frequency, or PRB location.

[0118] As another possible implementation, when the first terminal receives the channel occupancy time on unlicensed resources sent by the second terminal, it can receive information sharing signaling sent by the second terminal and determine the channel occupancy time on the unlicensed resources based on the information sharing signaling. The information sharing signaling sent by the second terminal may include channel occupancy time and auxiliary information, etc.

[0119] In addition to including at least one of the following: the unlicensed frequency identifier where the channel occupancy time is located, the Sidelink resource pool identifier where the channel occupancy time is located, the start time of the channel occupancy time, the end time of the channel occupancy time, the duration of the channel occupancy time, the channel access priority (CAPC) allowed for access during the channel occupancy time, and the allowed transmission methods during the channel occupancy time, the auxiliary information may also include the Sidelink identifier of the second terminal sending the information sharing signaling. The Sidelink identifier of the second terminal may be the identifier of the Sidelink between the first and second terminals. Furthermore, the Sidelink identifier of the second terminal may be a Sidelink Layer 2 address.

[0120] In step 502, the first terminal sends auxiliary information related to channel occupancy time to the network-side device.

[0121] The implementation of step 502 can refer to the above-mentioned related embodiments, and will not be repeated here.

[0122] Figure 6 This is a communication timing diagram illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 6 As shown, the first terminal can receive the channel occupancy time of the unlicensed sub-element sent by the second terminal. Based on this, the first terminal can determine that there is channel occupancy time on the unlicensed resource. Then, the first terminal can send auxiliary information related to the channel occupancy time to the network-side device.

[0123] In this embodiment, the channel occupancy time determined by the first terminal can be sent by the second terminal device. This can accelerate the acquisition rate of the channel occupancy time to a certain extent, thereby improving the acquisition rate of auxiliary information. Furthermore, this application also enables the first terminal to perform sidelink transmission on scheduled unlicensed resources, thereby improving the data transmission success rate or reducing data transmission latency.

[0124] Figure 7 This is a flowchart illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 7 As shown, this auxiliary information reporting method can be used in the first terminal and includes the following steps.

[0125] In step 701, the first terminal determines that there is channel occupancy time on the unlicensed resource.

[0126] The implementation of step 701 can refer to the above-mentioned related embodiments, and will not be repeated here.

[0127] In step 702, the first terminal sends auxiliary information related to the channel occupancy time to the network-side device based on a preset period.

[0128] As one possible implementation, the first terminal can trigger the transmission of auxiliary information to the network-side device based on a preset period. The preset period can be a period configured by the network-side device, meaning it can be transmitted to the first terminal by the network-side device through unlicensed resources. After determining that there is channel occupancy time on the unlicensed resources, the first terminal can first obtain the preset period from the unlicensed resources, and then send the auxiliary information related to the channel occupancy time to the network-side device based on this preset period. Alternatively, the preset period can also be determined by the first terminal based on the data it needs to transmit; that is, the preset period can be determined according to the needs of the first terminal. The specific method of obtaining the preset period is not explicitly limited here.

[0129] In this embodiment, after determining that there is channel occupancy time on unlicensed resources, the first terminal can send auxiliary information related to the channel occupancy time to the network-side device based on a preset period. This ensures that the auxiliary information can be uploaded to the network-side device in a timely and effective manner. Furthermore, this application also enables the first terminal to perform sidelink transmission on scheduled unlicensed resources, thereby improving the success rate of data transmission or reducing data transmission latency.

[0130] Figure 8 This is a flowchart illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 8 As shown, this auxiliary information reporting method can be used in the first terminal and includes the following steps.

[0131] In step 801, the first terminal determines that there is channel occupancy time on the unlicensed resources.

[0132] The implementation of step 801 can refer to the above-mentioned related embodiments, and will not be repeated here.

[0133] In step 802, if the first terminal determines that the channel occupancy time exceeds the preset duration, it sends auxiliary information related to the channel occupancy time to the network-side device.

[0134] As one possible implementation, after determining that there is channel occupancy time on unauthorized resources, the first terminal can determine whether the duration of the channel occupancy time exceeds a preset duration. When it is determined that the duration of the channel occupancy time exceeds the preset duration, the first terminal can send auxiliary information related to the channel occupancy time to the network-side device. The preset duration can be set based on empirical values, pre-configured by the network-side device, or determined according to the actual needs of the first terminal. The actual needs of the first terminal may include the size of the data to be transmitted, the priority of the data to be transmitted, etc.

[0135] As an example, if the channel occupancy time for unauthorized resources transmitted by the network-side device is 4:00-5:00, and the first terminal determines that the channel occupancy time is 31 minutes (4:00-4:31), it is known by comparison that the channel occupancy time exceeds the preset time of 30 minutes. At this time, the first terminal can directly send the auxiliary information corresponding to the channel occupancy time of 4:00-4:31 to the network-side device.

[0136] In this embodiment, after determining that there is channel occupancy time on unlicensed resources, the first terminal can send auxiliary information related to the channel occupancy time to the network-side device based on a preset duration. That is, the first terminal sends auxiliary information to the network-side device when it determines that the channel occupancy time exceeds the preset duration. This allows for more flexible and effective delivery of auxiliary information to the network-side device. Furthermore, this application also enables the first terminal to perform sidelink transmission on scheduled unlicensed resources, thereby improving the data transmission success rate or reducing data transmission latency.

[0137] Figure 9 This is a flowchart illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 9 As shown, this auxiliary information reporting method can be used in network-side devices and includes the following steps.

[0138] In step 901, the network-side device receives auxiliary information sent by the first terminal.

[0139] As one possible implementation, the network-side device can receive auxiliary information sent by the first terminal. This auxiliary information can be obtained by the first terminal when it determines that there is channel occupancy time on unlicensed resources.

[0140] Optionally, the auxiliary information may include at least one of the following: the unlicensed frequency identifier where the channel occupancy time is located, the Sidelink resource pool identifier where the channel occupancy time is located, the start time of the channel occupancy time, the end time of the channel occupancy time, the duration of the channel occupancy time, the channel access priority (CAPC) allowed for access during the channel occupancy time, and the allowed transmission methods during the channel occupancy time. The specific details of which of the above information are included in the auxiliary information are not explicitly limited here and can be selected according to the actual situation.

[0141] As one possible implementation, the transmission method for channel occupancy time can include at least one of Sidelink discovery and Sidelink communication. Sidelink discovery refers to a method used to determine / establish the proximity of two or more Sidelink terminals (e.g., within the range for direct Sidelink communication) or to determine / establish the proximity of a first terminal to a second terminal. Sidelink discovery can be divided into open Sidelink discovery and restricted Sidelink discovery. Sidelink communication refers to a method where some or all communication data between Sidelink terminals can be communicated directly without going through network infrastructure. Sidelink communication can include unicast, multicast, or broadcast; that is, Sidelink communication can be divided into Sidelink broadcast communication, Sidelink multicast communication, and Sidelink unicast communication.

[0142] In step 902, the network-side device schedules resources during the channel occupancy time.

[0143] As one possible implementation, when the network-side device receives auxiliary information sent by the first terminal, it can schedule resources during the channel occupancy period. By receiving auxiliary information transmitted by the first terminal, this embodiment of the application can avoid the failure of the network-side device to schedule Sidelink resources on unlicensed frequencies, thereby reducing the probability of data transmission failure or reducing data transmission latency.

[0144] Figure 10 This is a flowchart illustrating an auxiliary information reporting method according to some other embodiments. For example... Figure 10 As shown, this auxiliary information reporting method can be used in network-side devices and includes the following steps.

[0145] In step 1001, the network-side device sends the unauthorized resources configured by the network-side device to the terminal.

[0146] In this embodiment, unlicensed resources may include unlicensed frequencies or sidelink resources on unlicensed frequencies. In other words, unlicensed resources can be unlicensed frequencies, sidelink resources on unlicensed frequencies, or sidelink resources on both unlicensed and unlicensed frequencies.

[0147] As another possible implementation, sidelink resources on unlicensed frequencies may include at least one of a sidelink resource pool, a time-domain location of the resource, and a frequency-domain location of the resource. The sidelink resource pool may be a sidelink transmission resource pool. For example, sidelink resources on unlicensed frequencies may include resource pool 1 and resource pool 2.

[0148] Furthermore, the time-domain location and frequency-domain location of a resource can be the time-domain location and frequency-domain location of a Sidelink resource, respectively. The time-domain location can be determined by the network-side device using at least one of period, subframe, or duration. The frequency-domain location can be determined by the network-side device using at least one of subband, frequency, or PRB location.

[0149] It is worth noting that when a network-side device sends unlicensed resources to a first terminal, it can first configure the unlicensed resources for the first terminal. As described above, unlicensed resources can include time-domain location and frequency-domain location. When obtaining the time-domain location, the network-side device can first obtain at least one of the period, subframe, or duration, and then determine the time-domain location based on these parameters. Similarly, when obtaining the frequency-domain location, the network-side device can also first obtain at least one of the subband, frequency, or PRB location, and then determine the frequency-domain location based on these parameters.

[0150] As another possible implementation, the unauthorized resource may also include a preset period or a preset duration. The preset period can be used to instruct the first terminal to send auxiliary information related to channel occupancy time to the network-side device based on the preset period. Conversely, the preset duration can be used to instruct the first terminal to send auxiliary information related to channel occupancy time to the network-side device if it is determined that the channel occupancy time exceeds the preset duration.

[0151] In step 1002, the network-side device receives auxiliary information sent by the first terminal.

[0152] In step 1003, the network-side device schedules resources during the channel occupancy time.

[0153] The implementation methods for steps 1002 to 1003 can refer to the above-mentioned related embodiments, and will not be repeated here.

[0154] Figure 11 This is a communication timing diagram illustrating an auxiliary information reporting method according to some embodiments. For example... Figure 11 As shown, the network-side device can send unlicensed resources configured by the network-side device to the first terminal. After receiving the unlicensed resources, the first terminal can determine whether there is channel occupancy time on the unlicensed resources. If the first terminal determines that there is channel occupancy time on the unlicensed resources, it can send auxiliary information related to the channel occupancy time to the network-side device. In response to the auxiliary information, the network-side device can schedule resources within the channel occupancy time. The unlicensed resources may include unlicensed frequencies or sidelink resources on unlicensed frequencies. This application, by utilizing the first terminal to determine the channel occupancy time on the unlicensed resources, can avoid LBT failure and thus ensure that the first terminal performs sidelink transmission on the scheduled unlicensed resources.
