Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and apparatus for sharing the Channel Occupancy Time (COT) of a frame-structured device (FBE). Background Technology

[0002] In the frame-based equipment (FBE) channel access mode, the user equipment (UE) can currently autonomously activate the channel occupancy time (COT) for uplink transmission and then share the remaining COT with the next-generation Node B (gNB). The gNB then shares the COT with other UEs for uplink transmission via downlink transmission, thereby improving FBE channel access efficiency. However, this sharing method suffers from problems such as "fixed frame period (FFP) parameter confusion" and "inability to reclaim channel usage rights," rendering the sharing method unusable. Currently, there is a lack of effective means to resolve these issues. Summary of the Invention

[0003] This application provides a method and apparatus for sharing Channel Occupancy Time (COT) of a device FBE based on a frame structure. By sending indication information from a first terminal device to a network device, indicating the FFP where the currently enabled COT is located, the network device can indicate the parameter information of the FFP to other terminal devices. This allows the network device and the second terminal device sharing the COT of the first terminal device to occupy the COT shared by the first terminal device according to the parameter information of the FFP, thus solving the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0004] In a first aspect, embodiments of this application provide a method for sharing the COT of an FBE, executed by a first terminal device. The method includes: sending indication information to a network device by the first terminal device to indicate the fixed frame period (FFP) in which the currently enabled COT is located, wherein the indication information includes at least parameter information of the FFP.

[0005] The application provides a method for sharing the COT of an FBE. By sending indication information from a first terminal device to a network device, indicating the FFP where the currently enabled COT is located, the network device can indicate the parameter information of the FFP to other terminal devices. This allows the network device and the second terminal device sharing the COT of the first terminal device to occupy the COT shared by the first terminal device according to the parameter information of the FFP, which can solve the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0006] Secondly, embodiments of this application provide a method for sharing the COT of an FBE, executed by a network device. The method includes: receiving indication information sent by a first terminal device, wherein the indication information includes at least parameter information of the FFP where the COT currently enabled by the first terminal device is located; and sending the indication information to at least one second terminal device.

[0007] The application provides a method for sharing the COT of an FBE, which receives an indication message sent by a first terminal device and indicates the parameter information of the FFP where the COT currently enabled by the first terminal device is located to at least one second terminal device. This allows the network device and the second terminal device that share the COT of the first terminal device to occupy the COT shared by the first terminal device according to the parameter information of the FFP, thereby solving the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0008] Thirdly, embodiments of this application provide a method for sharing a COT of an FBE, executed by a second terminal device. The method includes: obtaining indication information sent by a network device, wherein the indication information includes at least parameter information of the FFP where the COT currently enabled by the first terminal device is located; and performing uplink transmission within the shared COT segment of the currently enabled COT based on the indication information.

[0009] This application provides a method for sharing the COT of an FBE (Functional Beacon). By obtaining the parameter information of the FFP (Functional Function Point) from the indication information sent by the network device, uplink transmission is performed within the shared COT segment of the currently enabled COT based on the indication information. A second terminal device can perform uplink transmission on the shared COT segment of the first terminal device according to the indicated FFP parameter information. Based on the FFP's identification information, it can be determined that the FFP containing the shared COT segment belongs to the first terminal device, not the network device, thus solving the problem of "FFP parameter confusion." Furthermore, based on the shared COT parameters, the second terminal device can avoid continuously occupying the first terminal device's COT, thereby enabling the first terminal device to promptly reclaim the channel usage right, solving the problem of "inability to reclaim channel usage right."

Detailed Implementation

[0043] 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 numbers 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 application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] To facilitate understanding, the terminology used in this application will be introduced first.

[0045] 1. Frame-based equipment (FBE) FBE is a listen-before-talk (LBT) channel access mode with a fixed frame structure. Figure 1 This is a schematic diagram of the FBE frame structure, which consists of multiple fixed-period FFPs.

[0046] 2. Fixed Frame Period (FFP) FFP is a constituent element of the FBE frame structure, such as Figure 1 As shown, an FFP includes the Channel Occupancy Time (COT) and the Idle Period (IP). The last 9µs of the Idle Period is the time for the node to perform Clear Channel Assessment (CCA). The FFP length can be configured from 1 to 10ms, and the configured value must remain unchanged for 200ms. The COT length within one FFP cannot exceed 95% of the FFP length, and the IP length is Max{5%•FFP, 100µs}.

[0047] 3. Channel occupancy time (COT) When CCA determines that the channel is idle, the terminal device or network device can enable COT and transmit data within COT.

[0048] To better understand the method for sharing the Channel Occupancy Time (COT) of a frame-structured device (FBE) disclosed in this application, the communication system to which this application is applicable is described below.

[0049] Please see Figure 2 , Figure 2 This application provides a schematic diagram of the architecture of a communication system according to an embodiment. The communication system may include, but is not limited to, a network device and a terminal device. Figure 2The 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 2 The communication system shown is an example including a network device 21 and a terminal device 22.

[0050] 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, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems, etc.

[0051] The network device 21 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 21 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 application 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.

[0052] In this embodiment, the terminal device 22 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. Terminal devices can be communication-enabled vehicles, smart cars, mobile phones, IoT devices such as NB-IoT or (e)MTC, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, and so on. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0053] 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.

[0054] It is understood that the multiple solutions in the embodiments of this application can be implemented individually or in combination, and this application does not limit them in this regard.

[0055] The following description, in conjunction with the accompanying drawings, details the method and apparatus for sharing Channel Occupancy Time (COT) of a frame-structured device (FBE) provided in this application.

[0056] Figure 3 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. The method is applied to a first terminal device, such as... Figure 3 As shown, the method includes: S31, send indication information to the network device for the first terminal device to indicate the FFP where the currently enabled COT is located, wherein the indication information includes at least the parameter information of the FFP.

[0057] In related technologies, terminal devices can independently enable FBE COT and share the FBE COT they have enabled with network devices. Based on this characteristic, a new COT sharing method can be developed, namely "FBE COT sharing between terminal devices with network devices as the connection point".

[0058] The FBE COT refers to the channel occupancy time determined by the terminal after performing channel detection via FBE and passing the channel detection.

[0059] In this embodiment, the first terminal device (UE1) autonomously enables FBE COT. After the COT performs uplink transmission, it can share the remaining COT with the network device. The network device performs downlink transmission on the shared COT. After detecting the downlink transmission, the second terminal device (UE2) mistakenly believes that the COT enabled by the network device is the COT enabled by the first terminal device and then shares the COT enabled by the first terminal device for uplink transmission.

[0060] It should be noted that the first terminal device is the terminal device that independently enables COT, and the second terminal device is the terminal device that shares the COT enabled by the first terminal device. There must be at least one second terminal device.

[0061] Down Figure 4 The example shown illustrates how UE2 shares the COT (with gNB as the connection point) enabled by UE1, completing the transmission of high-priority data traffic within UE1's COT without waiting for the next FFP, thus reducing latency. However, this new sharing method suffers from issues such as "FFP parameter confusion" and "inability to reclaim channel usage rights," rendering it unusable.

[0062] "FFP parameter confusion" refers to a situation where, when a first terminal device independently activates a COT (Content on the Network Device), the starting position and length of the FFP (Functional File System) on the first terminal device may differ from those on the network device. A second terminal device may mistakenly treat the COT activated by the first terminal device as the COT activated by the network device and share it, leading to FFP parameter confusion. This results in the incorrect identification of the active FFP containing the shared COT as the FFP of the network device. A specific example can be found here. Figure 5 .

[0063] "Unable to reclaim channel usage rights" means that when the first terminal device wants to reclaim the channel usage rights and resume uplink transmission, the channel may still be used by the second terminal device, rendering the first terminal device unable to use it. A specific example can be found here. Figure 6 .

[0064] To improve the aforementioned COT sharing method, in this embodiment, after the first terminal device autonomously activates the COT, it sends indication information of the FFP (Factor Platform) where the currently activated COT resides to the network device. The indication information includes FFP parameter information; optionally, the parameter information includes at least the FFP's identification information and / or the sharing parameters of the currently activated COT. The network device and the second terminal device can occupy the COT based on the FFP parameter information in the indication information, avoiding the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights."

[0065] Optionally, the FFP identification information can be used to indicate that the FFP containing the shared COT belongs to the first terminal device. Based on the FFP identification, the second terminal device can determine that the shared COT is the COT enabled by the first terminal device, rather than the COT enabled by the network device, thereby solving the problem of "FFP parameter confusion" through the FFP identification information.

[0066] Optionally, the sharing parameters include the sharing start position of the COT and / or the sharing duration of the COT. It should be noted that the sharing start position is used to indicate the starting point on the COT of the first terminal device that is allowed to be shared, and the sharing duration is the length of time that the COT of the first terminal device is allowed to be shared.

[0067] Optionally, the FFP's parameter information may also include the FFP's length and start position. The COT's sharing parameters may also include the COT's sharing end position. The sharing start position and sharing duration can determine the sharing end position, and the COT's sharing end position and sharing start position can determine the sharing duration.

[0068] In this embodiment, the sharing parameter can indicate the COT segments that the first terminal device is allowed to share. The second terminal device and the network device need to share the COT segments that the first terminal device is allowed to share based on the sharing parameter. The COT segments exceeding the limits indicated by the sharing parameter will not be able to be shared by the network device and the second terminal device. That is, the first terminal device can reclaim the right to use the channel. Thus, the problem of "unable to reclaim the right to use the channel" can be solved by the sharing parameter.

[0069] In some implementations, the indication information carrying FFP parameter information can be sent separately by the first terminal device to the network device via signaling. In other implementations, the indication information carrying FFP parameter information can be sent synchronously by the first terminal device to the network device via uplink transmission. For example, the first terminal device can send the indication information to the network device by configuring Grant Uplink Control Information (CG-UCI).

[0070] Optionally, the FFP identification information and COT shared parameters can be sent to the network device along with the indication information, or the FFP identification information and shared parameters can be reported to the network device separately through their respective indication information.

[0071] In this embodiment, the network device can send indication information to the second terminal device. There can be one or more second terminal devices. Based on the FFP identification information, the network device and the second terminal device can determine that the shared COT is the COT enabled by the first terminal device, not the COT enabled by the network device, thus resolving the "FFP parameter confusion" problem through the FFP identification information. The second terminal device and the network device need to share the COT segments allowed to be shared by the first terminal device based on the sharing parameters. COT portions exceeding the limits indicated by the sharing parameters cannot be further shared by the network device and the second terminal device; that is, the first terminal device can reclaim the right to use the channel. Therefore, the problem of "inability to reclaim the right to use the channel" can be resolved through the sharing parameters.

[0072] This application provides a method for sharing the COT of an FBE. By sending an indication information of the FFP where the COT currently enabled by the first terminal device is located to the network device, the network device can indicate the parameter information of the FFP to other terminal devices. This allows the network device and the second terminal device that share the COT of the first terminal device to occupy the COT shared by the first terminal device according to the parameter information of the FFP, which can solve the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0073] Figure 7 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. The method is applied to a first terminal device, such as... Figure 7 As shown, the method includes: S71, determine the indication information used by the first terminal device to indicate the FFP where the currently enabled COT is located.

[0074] In this embodiment, the indication information includes FFP parameter information, wherein the FFP parameter information includes FFP identification information and / or the sharing parameters of the currently enabled COT, and the COT sharing parameters include the COT sharing start position and / or the COT sharing duration. Optionally, the COT sharing parameters may also include the COT sharing end position.

[0075] For details on FFP parameter information, please refer to the relevant descriptions in the embodiments of this application; they will not be repeated here.

[0076] S72 sends indication information to network devices during uplink transmissions within the currently enabled COT.

[0077] After the first terminal device autonomously enables COT, it can perform uplink transmission on the enabled COT. Optionally, the first terminal device performs CCA during the idle time IP of FFP. In response to the evaluation result of CCA being that the channel is idle, it starts uplink transmission within the currently enabled COT and sends indication information to the network device during uplink transmission.

[0078] Optionally, the first terminal device may carry indication information in the uplink transmission to send the indication information to the network device.

[0079] As one possible implementation, the uplink transmission from the first terminal device may continue for a period of time, and the indication information can be sent to the network device at any point during the uplink transmission. In some implementations, the first terminal device can send the indication information to the network device at the beginning of the uplink transmission; in other implementations, the first terminal device can send the indication information to the network device at the middle of the uplink transmission; and in still other implementations, the first terminal device can send the indication information to the network device at the end of the uplink transmission. Optionally, the FFP identification information and COT shared parameters included in the FFP parameter information can be indicated to the network device together in the same phase of the uplink transmission, or they can be indicated to the network device separately in different phases. For example, the FFP identification information can be sent to the network device at the beginning or middle of the uplink transmission, and the COT shared parameters can be sent to the network device at the end of the uplink transmission.

[0080] In this embodiment, the network device can send indication information to a second terminal device. There can be one or more second terminal devices. Based on the FFP identifier, the network device and the second terminal device can determine that the shared COT is the COT enabled by the first terminal device, not the COT enabled by the network device, thereby resolving the "FFP parameter confusion" problem through the FFP identifier information.

[0081] The second terminal device and the network device need to share the COT segments that the first terminal device is allowed to share based on the sharing parameters. The COT segments exceeding the limits indicated by the sharing parameters will no longer be shared by the network device and the second terminal device. In other words, the first terminal device can reclaim the right to use the channel, and thus the problem of "unable to reclaim the right to use the channel" can be solved by the sharing parameters.

[0082] The method for sharing the COT of an FBE provided in this application embodiment further includes the following steps: Optionally, the indication information also includes a COT sharing indication, which indicates whether the currently enabled COT should be shared. If the first terminal device allows sharing of the currently enabled COT, the COT sharing indication tells the network device that sharing of the currently enabled COT is permissible. If the first terminal device does not allow sharing of the currently enabled COT, the COT sharing indication tells the network device that sharing of the currently enabled COT is not permissible. Alternatively, it can be determined by communication protocols or other means that the first terminal device defaults to not allowing sharing of the currently enabled COT, and only allows sharing of the currently enabled COT if the network device receives an explicit indication.

[0083] Optionally, the network device can determine whether to send indication information to the second terminal device based on the COT sharing indication. In one embodiment, if it is determined that the first terminal device allows the currently enabled COT to be shared, the network device sends the indication information to the second terminal device. In another embodiment, if it is determined that the first terminal device does not allow the currently enabled COT to be shared, the network device does not send the indication information to the second terminal device.

[0084] This application provides a method for sharing the Channel Access Point (COT) of an FBE (Functional Beam Environment). By determining the indication information of the FFP (Functional Function Platform) where the COT currently enabled by the first terminal device is located, the indication information can be sent to the network device during uplink transmission within the currently enabled COT. In this way, the network device can determine the parameter information of the FFP and indicate it to other terminal devices. This allows the network device and the second terminal device sharing the COT of the first terminal device to occupy the COT shared by the first terminal device according to the parameter information of the FFP, thus solving the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0085] Figure 8 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. The method is applied to a first terminal device, such as... Figure 8 As shown, the method includes: S81, determine the remaining COT segment when the uplink transmission of the first terminal device ends, and use it as a shared COT segment.

[0086] After the first terminal device autonomously enables COT (Content-On-Demand), it can perform uplink transmission on the enabled COT. After the uplink transmission ends, to improve channel utilization, the remaining COT segments can be used as shared COT segments. These shared COT segments can be shared with network devices for downlink transmission, or shared with a second terminal device via the network device for uplink transmission. The second terminal device is the terminal device that shares the COT enabled by the first terminal device; there must be at least one second terminal device.

[0087] As one possible implementation, at the start of uplink transmission, based on the time-domain resource occupancy of the uplink transmission, the COT segment that the first terminal device needs to occupy can be determined, and then the remaining COT segments can be determined as shared COT segments. As another possible implementation, at the end of uplink transmission, the remaining unused COT segments are determined as shared COT segments.

[0088] S82 determines the shared parameters based on the format configuration information of the transmission time domain unit in the shared COT segment.

[0089] Optionally, the transmission time domain unit can be a slot, a symbol within a slot, or any other arbitrary time domain unit.

[0090] In this embodiment, sharing parameters can be determined based on the format configuration information of the transmission time domain units in the shared COT segment. Optionally, the format configuration information includes uplink transmission time domain units and downlink transmission time domain units. Based on the format configuration information, the starting position and duration of sharing the COT are determined, i.e., the sharing start position and sharing duration of the COT. The sharing start position and / or sharing duration of the COT are then used as the sharing parameters of the COT.

[0091] In all embodiments of this disclosure, the sharing parameters of the COT may include at least one of the following parameters: the sharing start position of the COT, the sharing end position of the COT, and the sharing duration of the COT. Furthermore, the relevant parameters for sharing the COT segment can be determined by combining the sharing parameters of the COT with the communication standard or preset configuration. For example, in some implementations, the sharing start position of the COT may be one or more of the following: the sharing start position of the network device, or the sharing start position of the second terminal device.

[0092] Optionally, the first downlink transmission time domain unit in the remaining COT segment can be used as the shared start position of the network device, which can instruct the network device to share the COT of the first terminal device for downlink transmission at the start position; the first uplink transmission time domain unit in the remaining COT segment can be used as the shared start position of the second terminal device, which can instruct the second terminal device to share the COT of the first terminal device for uplink transmission at the start position.

[0093] Accordingly, the sharing start position of the network device has a corresponding sharing duration, indicating that the network device shall perform downlink transmission within the specified sharing duration; the sharing start position of the second terminal device has a corresponding sharing duration, indicating that the second terminal device shall perform uplink transmission within the specified sharing duration.

[0094] Optionally, the last downlink transmission time domain unit in the remaining COT segment is used as the sharing end position of the network device, and the sharing duration of the network device is determined based on the sharing start position and sharing end position of the network device; the last uplink transmission time domain unit in the remaining COT segment is used as the sharing end position of the second terminal device, and the sharing duration of the second terminal device is determined based on the sharing start position and sharing end position of the second terminal device. Optionally, in order to ensure that the first terminal device can perform uplink transmission in a timely manner, some subsequent uplink transmission time domain units can be reserved, that is, the reserved uplink transmission time domain units are not allowed to be shared.

[0095] In all embodiments of this disclosure, the sharing start position and / or sharing end position can be determined using default methods (e.g., communication protocols or pre-configuration). For example, if the time domain unit is a symbol, the first symbol in the remaining COT segment can be used as the default sharing start position for downlink transmission of the network device; if the time domain unit is a slot, the first symbol in the first slot of the remaining COT segment can be used as the default sharing start position for downlink transmission of the network device. Similarly, the sharing start position for the second terminal device can also be a default position. Furthermore, the order of the sharing start position for downlink transmission of the network device and the sharing start position for the second terminal device is not limited. For example, downlink transmission of the network device can be performed first, followed by transmission of the second terminal device; or other orders can be used. The sharing start position for downlink transmission of the network device and the sharing start position for the second terminal device can be either absolute or relative to the remaining COT segment. For example, if downlink transmission of the network device is performed first, a default relative position after the end of downlink transmission of the network device can be used as the sharing start position for the second terminal device. For example, if the shared transmission of the second terminal device is performed first, a default relative position after the transmission ends can be used as the starting position for the shared transmission of the network device's downlink transmission. Alternatively, the absolute positions of the network device's downlink transmission and the second terminal device's shared transmission can be pre-determined for the remaining COT segments.

[0096] S83 generates a shared configuration table based on the COT shared instruction and FFP parameter information, and uses the shared configuration table as instruction information.

[0097] The COT sharing instruction and FFP parameter information are obtained, including the FFP identification information and the COT sharing parameters. A sharing configuration table is generated, and the sharing configuration table is used as the instruction information. For a detailed description of the COT sharing instruction and FFP parameter information, please refer to the relevant descriptions in the various embodiments of this application, which will not be repeated here.

[0098] It should be noted that in FBE mode, the first terminal device can configure higher-layer parameters and send a shared configuration table to the network device through these parameters. The shared configuration table can include multiple rows, each optionally corresponding to parameter information for a type of FFP. Optionally, the first row is the shared start position of the COT, for example, it can be represented as X+O, where X is the slot offset and O is the symbol offset, meaning that shared transmission is allowed to start from X+O. The second row is the shared duration of the COT, which can be a symbol-level duration. The third row is the identification information of the FFP where the COT currently enabled by the first terminal device resides, optionally also including the start position of the FFP, the length of the FFP, etc.; the fourth row is the COT sharing indication.

[0099] S84 sends the instruction information to the network device.

[0100] The implementation method of step S84 can be any of the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0101] In this embodiment, the network device can send indication information to a second terminal device. There can be one or more second terminal devices. Based on the FFP identifier, the network device and the second terminal device can determine that the shared COT is the COT enabled by the first terminal device, not the COT enabled by the network device, thereby resolving the "FFP parameter confusion" problem through the FFP identifier information.

[0102] The second terminal device and the network device need to share the COT segments that the first terminal device is allowed to share based on the sharing parameters. The COT segments exceeding the limits indicated by the sharing parameters will no longer be shared by the network device and the second terminal device. In other words, the first terminal device can reclaim the right to use the channel, and thus the problem of "unable to reclaim the right to use the channel" can be solved by the sharing parameters.

[0103] This application provides a method for sharing the Channel Access Point (COT) of an IF (Front-End Network). The method involves identifying the remaining COT segment at the end of uplink transmission on a first terminal device as a shared COT segment. Based on the format configuration information of the transmission time-domain units (TTUs) in the shared COT segment, sharing parameters are determined. A sharing configuration table is generated based on the COT sharing indication and the FFP (Forwarded Function Point) identification information. This shared configuration table is then sent to the network device as indication information. In this way, the FFP identification information, COT sharing parameters, and COT sharing indication can be sent to the network device together. The COT sharing indication and parameters indicate whether the currently enabled COT should be shared and the duration of sharing, preventing a second terminal device from continuously occupying the first terminal device's COT and preventing the first terminal device from reclaiming channel usage rights. Furthermore, the FFP identification information prevents FFP parameter confusion, ensuring that the second terminal device does not mistake the shared COT for a COT enabled by the network device.

[0104] Figure 9 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. This method is applied to network devices, such as... Figure 9 As shown, the method includes: S91, receive indication information sent by the first terminal device, wherein the indication information includes at least the parameter information of the FFP where the COT currently enabled by the first terminal device is located.

[0105] In this embodiment, the indication information includes FFP parameter information, which includes FFP identification information and / or currently enabled COT sharing parameters. The COT sharing parameters include the COT sharing start position and / or COT sharing duration. Optionally, the COT sharing parameters may also include the COT sharing end position. For a detailed description of the FFP parameter information, please refer to the relevant descriptions in any embodiment of this application; further details will not be repeated here.

[0106] Optionally, the device may receive instruction information sent by the first terminal device via uplink transmission; or it may receive instruction information sent by the first terminal device via signaling.

[0107] In some implementations, the indication information carrying FFP parameter information can be sent separately by the first terminal device to the network device via signaling. In other implementations, the indication information carrying FFP parameter information can be sent synchronously by the first terminal device to the network device via uplink transmission. For example, the first terminal device can send the indication information to the network device via CG-UCI.

[0108] Optionally, the FFP identification information and the COT shared parameters can be simultaneously carried in the indication information sent to the network device, or the FFP identification information and the COT shared parameters can be reported to the network device separately through their respective indication information. Correspondingly, the network device can receive indication information carrying both the FFP identification information and the COT shared parameters, or it can receive one indication information carrying the FFP identification information and another indication information carrying the COT shared parameters separately.

[0109] Optionally, the network device can receive a shared configuration table, which includes indication information, namely, the identification information of the FFP and the sharing parameters of the COT. It should be noted that in FBE mode, the first terminal device can configure higher-layer parameters and send the shared configuration table to the network device through these higher-layer parameters. The shared configuration table can include multiple rows, and optionally, each row can correspond to parameter information for a type of FFP. Optionally, the first row is the sharing start position of the COT, for example, it can be represented as X+O, where X is the time slot offset and O is the symbol offset, meaning that shared transmission is allowed to start from X+O. The second row is the sharing duration of the COT, which can be a symbol-level duration; the third row is the identification information of the FFP where the COT currently enabled by the first terminal device resides, and optionally may also include the starting position of the FFP, the length of the FFP, etc.; the fourth row is the COT sharing indication.

[0110] S92, send instruction information to at least one second terminal device.

[0111] In some implementations, the network device can schedule at least one second terminal device to perform uplink transmission within the COT of the first terminal device and send indication information to the scheduled second terminal device in order to improve the utilization rate of the COT of the first terminal device.

[0112] In other implementations, network devices broadcast indication information during downlink transmission to notify the first terminal device of the indication information of the second terminal device being scheduled.

[0113] In this embodiment, the network device can send indication information to a second terminal device. There can be one or more second terminal devices. Based on the FFP identifier, the network device and the second terminal device can determine that the shared COT is the COT enabled by the first terminal device, not the COT enabled by the network device, thereby resolving the "FFP parameter confusion" problem through the FFP identifier information.

[0114] The second terminal device and the network device need to share the COT segments that the first terminal device is allowed to share based on the sharing parameters. The COT segments exceeding the limits indicated by the sharing parameters will no longer be shared by the network device and the second terminal device. In other words, the first terminal device can reclaim the right to use the channel, and thus the problem of "unable to reclaim the right to use the channel" can be solved by the sharing parameters.

[0115] The method for sharing the COT of an FBE provided in this application embodiment further includes the following steps: Optionally, the indication information also includes a COT sharing indication, which is used to indicate the relevant operations for sharing the currently enabled COT. If the first terminal device allows sharing of the currently enabled COT, the COT sharing indication tells the network device that the currently enabled COT can be shared. If the first terminal device does not allow sharing of the currently enabled COT, the COT sharing indication tells the network device that the currently enabled COT cannot be shared. Of course, as mentioned above, a default setting on / off mode can also be used, and the default setting can be explicitly canceled.

[0116] Optionally, the network device may determine whether to send indication information to the second terminal device based on the COT sharing indication. If it is determined that the first terminal device allows the currently enabled COT to be shared, the network device will send the indication information to the second terminal device; if it is determined that the first terminal device does not allow the currently enabled COT to be shared, the network device will not send the indication information to the second terminal device.

[0117] This application provides a method for sharing the COT of an FBE, which receives an indication message sent by a first terminal device and indicates the parameter information of the FFP where the COT currently enabled by the first terminal device is located to at least one second terminal device. This allows the network device and the second terminal device that share the COT of the first terminal device to occupy the COT shared by the first terminal device according to the parameter information of the FFP, thereby solving the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0118] Figure 10 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. This method is applied to network devices, such as... Figure 10 As shown, the method includes: S101, receive indication information sent by the first terminal device, wherein the indication information includes at least the parameter information of the FFP where the COT currently enabled by the first terminal device is located.

[0119] The system receives indication information transmitted via uplink from a first terminal device. This indication information includes at least parameter information of the FFP (Flexible Feeder Platform) where the currently enabled COT (Content Controller) resides. Optionally, the parameter information includes at least the FFP's identification information and / or the sharing parameters of the currently enabled COT, where the sharing parameters include the COT's sharing start position and / or the COT's sharing duration. Optionally, the indication information also includes a COT sharing indication, used to indicate whether to share the currently enabled COT.

[0120] For details regarding the FFP identification information and the specific content of the COT shared parameters included in the FFP parameter information, please refer to the relevant descriptions in the various embodiments of this disclosure, which will not be repeated here.

[0121] S102, the second terminal device is scheduled based on downlink control information (DCI), and the indication information is sent to the second terminal device via DCI.

[0122] When a network device wants to schedule a specific second terminal device to share COT, it can send DCI to the scheduled second terminal device on the Physical Downlink Control Channel (PDCCH) and send the indication information to the second terminal device through the DCI.

[0123] Optionally, the indication information also includes a COT sharing indication, wherein the COT sharing indication is used to indicate whether the currently enabled COT should be shared. If the first terminal device allows sharing of the currently enabled COT, the COT sharing indication indicates to the network device that the currently enabled COT can be shared. If the first terminal device does not allow sharing of the currently enabled COT, the COT sharing indication indicates to the network device that the currently enabled COT cannot be shared.

[0124] In this embodiment, before sending indication information to the second terminal device, the network device can determine whether to send indication information to the second terminal device based on the COT sharing indication. If the COT sharing indication allows the first terminal device to share the currently enabled COT, the network device sends the indication information to the second terminal device. If the COT sharing indication does not allow the first terminal device to share the currently enabled COT, the network device will not send the indication information to the second terminal device. This embodiment provides a method for sharing the COT of an FBE, receiving indication information sent by the first terminal device, wherein the indication information includes at least the parameter information of the FFP where the COT currently enabled by the first terminal device is located, and can send the indication information to the scheduled second terminal device through DCI to instruct the second terminal device to share the COT shared by the first terminal device according to the FFP parameters, so that the network device and the second terminal device sharing the COT of the first terminal device can occupy the COT shared by the first terminal device according to the FFP parameter information, which can solve the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0125] Figure 11 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. This method is applied to network devices, such as... Figure 11 As shown, the method includes: S111, receive indication information sent by the first terminal device, wherein the indication information includes at least the parameter information of the FFP where the COT currently enabled by the first terminal device is located.

[0126] The implementation method of step S111 can be any of the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0127] S112, in response to the current enabled COT being allowed to be shared, downlink transmission is performed on the shared COT segment within the currently enabled COT.

[0128] Optionally, the indication information also includes a COT sharing indication, wherein the COT sharing indication is used to indicate whether the currently enabled COT should be shared. If the first terminal device allows sharing of the currently enabled COT, the COT sharing indication indicates to the network device that the currently enabled COT can be shared. If the first terminal device does not allow sharing of the currently enabled COT, the COT sharing indication indicates to the network device that the currently enabled COT cannot be shared.

[0129] Based on the COT sharing instruction, it is determined that the currently enabled COT can be shared. Network devices can then initiate downlink transmissions on the shared COT segment, starting from the sharing start position. In some implementations, the network device initiates downlink transmissions from the sharing start position of the COT and completes the downlink transmission within the sharing duration of the COT. In other implementations, the sharing start position of the COT includes the sharing start position of both the network device and the second terminal device, and the sharing duration of the COT includes the sharing duration of both the network device's COT and the second terminal device's COT. A network device can initiate downlink transmissions from its corresponding sharing start position and complete the downlink transmission within the sharing duration corresponding to its COT.

[0130] S113, the instruction information is sent to the second terminal device via downlink transmission.

[0131] Network devices can broadcast indication information during downlink transmissions, sending the indication information to all second terminal devices that detect the downlink transmission.

[0132] As one possible implementation, the downlink transmission by the network device may continue for a period of time, and the indication information can be sent to the second terminal device at any point during the downlink transmission. In some implementations, the network device can send the indication information to the second terminal device at the beginning of the downlink transmission; in other implementations, the network device can send the indication information to the second terminal device at the middle of the downlink transmission; and in still other implementations, the network device can send the indication information to the second terminal device at the end of the downlink transmission. Optionally, the FFP identification information and COT shared parameters included in the FFP parameter information can be indicated to the second terminal device together in the same phase of the downlink transmission, or they can be indicated to the second terminal device separately in different phases. For example, the FFP identification information can be sent to the network device at the beginning or middle of the downlink transmission, and the COT shared parameters can be sent to the network device at the end of the downlink transmission.

[0133] This application provides a method for sharing the COT of an FBE. In this method, it can be determined whether the currently enabled COT is allowed to be shared based on indication information. When sharing is allowed, an indication message is broadcast to a second terminal device via downlink transmission. This allows network devices and second terminal devices sharing the COT of the first terminal device to occupy the COT shared by the first terminal device based on the FFP parameter information, thus solving the problems of "FFP parameter confusion" and "inability to reclaim channel usage rights".

[0134] Figure 12 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. This method is applied to network devices, such as... Figure 12 As shown, the method includes: S121, receive indication information sent by the first terminal device, wherein the indication information includes at least the parameter information of the FFP where the COT currently enabled by the first terminal device is located.

[0135] The implementation method of step S121 can be any of the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0136] S122, in response to the current enabled COT being allowed to be shared, downlink transmission is performed on the shared COT segment within the currently enabled COT.

[0137] The implementation method of step S122 can be any of the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0138] S123, determine the occupancy information of the shared COT segment for downlink transmission of the network device.

[0139] When network devices need to perform downlink transmission, they may share part or all of the COT segment. Optionally, the COT segment occupied by the network device at the end of the downlink transmission can be determined. One possible implementation is to determine the COT segment occupied by the network device at the start of the downlink transmission based on the time-domain resource occupancy of the downlink transmission. Another possible implementation is to determine the COT segment occupied by the network device at the end of the downlink transmission.

[0140] The information on network devices' occupancy of shared COT segments may include the duration of occupancy and / or the number of transmission time units occupied.

[0141] S124, update the parameter information of FFP in the indication information according to the occupancy information, and send the updated indication information to the second terminal device.

[0142] At this point, the remaining shared COT segment does not match the sharing parameters indicated in the indication information. In order to ensure that the second terminal device accurately occupies the remaining shared COT segment, the network device can update the indication information based on the occupancy time.

[0143] In some implementations, the sharing duration in the COT's sharing parameters can be updated based on the occupancy duration in the occupancy information, and the difference between the sharing duration and the occupancy duration can be used as the updated sharing duration. In other implementations, the sharing start position in the COT's sharing parameters can be re-determined and updated based on the occupied transmission time domain units in the occupancy information to obtain the updated sharing start position. Based on the updated sharing duration and the updated sharing start position, the updated COT sharing parameters are determined. The indication information is then updated based on the updated COT sharing parameters and sent to the second terminal device.

[0144] For example, if the downlink transmission of the network device occupies the entire shared COT segment, the updated sharing duration is 0, indicating that the second terminal device cannot share the channel and the channel is returned to the first terminal device. If the downlink transmission of the network device exceeds the shared COT segment, the network device immediately stops downlink transmission after exceeding the shared COT segment, the updated sharing duration is 0, indicating that the second terminal device cannot share the channel and the channel is returned to the first terminal device. If the downlink transmission of the network device does not occupy the entire shared COT segment, the updated sharing duration is determined based on the difference between the sharing duration and the occupied duration, and the updated sharing start position is determined based on the occupied transmission time domain units in the occupancy information, instructing the second terminal device to perform uplink transmission within the updated sharing duration and sharing start position.

[0145] This application provides a method for sharing a COT in an FBE. In this way, it can determine whether the currently enabled COT can be shared based on the indication information. When sharing is allowed, an indication message is broadcast to the second terminal device through downlink transmission. Based on the network device's occupancy of the shared COT, the indication information is updated so that the second terminal device can perform uplink transmission according to the updated indication information. This allows the second terminal to accurately determine the starting sharing position and sharing duration, and better perform uplink transmission on the remaining shared COT segments.

[0146] Figure 13 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. This method is applied to a second terminal device, such as... Figure 13 As shown, the method includes: S131, Obtain indication information sent by the network device, wherein the indication information includes at least the parameter information of the FFP where the COT currently enabled by the first terminal device is located.

[0147] In this embodiment, the indication information includes FFP parameter information, wherein the FFP parameter information includes FFP identification information and / or the sharing parameters of the currently enabled COT, and the COT sharing parameters include the COT sharing start position and / or the COT sharing duration. Optionally, the COT sharing parameters may also include the COT sharing end position.

[0148] For details regarding the FFP identification information and the specific content of the COT shared parameters included in the FFP parameter information, please refer to the relevant descriptions in the various embodiments of this disclosure, which will not be repeated here.

[0149] In some implementations, the network device can schedule at least one second terminal device to perform uplink transmission in the COT of the first terminal device and send indication information to the scheduled second terminal device in order to improve the utilization rate of the COT of the first terminal device. Accordingly, the second terminal device can receive the indication information.

[0150] In other implementations, network devices broadcast indication information during downlink transmission to notify the first terminal device of the indication information of the second terminal device, and the second terminal device can receive the indication information accordingly.

[0151] S132, based on the instruction information, perform uplink transmission within the shared COT segment of the currently enabled COT.

[0152] The second terminal device initiates uplink transmission from the sharing start position of COT based on the instruction information, and completes the uplink transmission within the sharing duration of COT.

[0153] In some implementations, if the network device does not share the COT for downlink transmission, the second terminal device will start uplink transmission from the starting position of COT sharing and complete the uplink transmission within the COT sharing duration.

[0154] In other implementations, the shared start position of COT includes the shared start position of the network device and the shared start position of the second terminal device, and the shared duration of COT includes the shared duration of the network device's COT and the shared duration of the second terminal device's COT. The second terminal device then begins uplink transmission from its shared start position and completes the uplink transmission within the shared duration of its COT.

[0155] In some implementations, after the network device performs downlink transmission using the shared COT, it updates the sharing start position and sharing duration in the indication information. The second terminal device then begins uplink transmission from the updated sharing start position and completes the uplink transmission within the updated sharing duration. In this embodiment of the application, the second terminal device can determine that the shared COT is the COT enabled by the first terminal device, rather than the COT enabled by the network device, based on the FFP identifier, thereby solving the problem of "FFP parameter confusion" through the FFP identifier information.

[0156] The second terminal device needs to share the COT segments that the first terminal device is allowed to share based on the sharing parameters. The COT segments exceeding the limits indicated by the sharing parameters will no longer be shared by the network device and the second terminal device. In other words, the first terminal device can reclaim the right to use the channel, and thus the problem of "unable to reclaim the right to use the channel" can be solved by the sharing parameters.

[0157] This application provides a method for sharing the COT of an FBE (Functional Beacon). By obtaining the parameter information of the FFP (Functional Function Point) from the indication information sent by the network device, uplink transmission is performed within the shared COT segment of the currently enabled COT based on the indication information. A second terminal device can perform uplink transmission on the shared COT segment of the first terminal device according to the indicated FFP parameter information. Based on the FFP's identification information, it can be determined that the FFP containing the shared COT segment belongs to the first terminal device, not the network device, thus resolving "FFP parameter confusion." Furthermore, based on the shared COT parameters, the second terminal device can avoid continuously occupying the first terminal device's COT, thereby enabling the first terminal device to promptly reclaim channel usage rights, solving the problem of "inability to reclaim channel usage rights."

[0158] Figure 14 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. This method is applied to a second terminal device, such as... Figure 14 As shown, the method includes: S141, Obtain indication information sent by the network device, wherein the indication information includes at least the identification information of the FFP where the COT currently enabled by the first terminal device is located.

[0159] The implementation method of step S141 can be any of the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0160] S142, Based on the FFP's identification information, determine the FFP containing the corresponding shared COT fragment.

[0161] After receiving the instruction information, the second terminal device can determine the FFP of the currently enabled shared COT based on the FFP identification information in the instruction information, thus avoiding misjudgment. For example, if the FFP identification information in the instruction information is 01, it is determined that the FFP of the shared COT is the FFP corresponding to the first terminal device UE1, that is, the first terminal device UE1 has autonomously enabled COT and performed sharing.

[0162] S143, uplink transmission is performed within a shared COT segment based on shared parameters.

[0163] In some implementations, if the network device does not share the COT for downlink transmission, the second terminal device will start uplink transmission from the starting position of COT sharing and complete the uplink transmission within the COT sharing duration.

[0164] In other implementations, the shared start position of COT includes the shared start position of the network device and the shared start position of the second terminal device, and the shared duration of COT includes the shared duration of the network device's COT and the shared duration of the second terminal device's COT. The second terminal device then begins uplink transmission from its shared start position and completes the uplink transmission within the shared duration of its COT.

[0165] In some implementations, after the network device performs downlink transmission using the shared COT, it updates the sharing start position and sharing duration in the indication information. The second terminal device then begins uplink transmission from the updated sharing start position and completes the uplink transmission within the updated sharing duration.

[0166] This application provides a method for sharing the COT of an FBE. This method allows for the determination, based on the FFP's identification information, that the FFP containing the shared COT segment belongs to a first terminal device, not a network device, thus resolving "FFP parameter confusion." Furthermore, by using the shared COT parameters, it prevents a second terminal device from continuously occupying the first terminal device's COT, thereby enabling the first terminal device to promptly reclaim channel usage rights and solving the problem of "inability to reclaim channel usage rights."

[0167] Figure 15 This is a flowchart illustrating a method for sharing the COT of an FBE according to an embodiment of this application. This method is applied to a second terminal device, such as... Figure 15 As shown, the method includes: S151, Obtain indication information sent by the network device, wherein the indication information includes at least the parameter information of the FFP where the COT currently enabled by the first terminal device is located.

[0168] The implementation method of step S151 can be any of the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0169] S152, determine the uplink transmission duration of the second terminal device.

[0170] Optionally, the uplink transmission duration can be determined based on the time-domain resource usage of the uplink transmission.

[0171] S153, based on the transmission duration and shared parameters, performs uplink transmission within the shared COT segment.

[0172] In response to a transmission duration less than or equal to the shared duration of the COT in the shared parameters, the uplink transmission is performed within the shared COT segment, starting from the shared position of the COT in the shared parameters.

[0173] In response to a transmission duration greater than the shared duration of COT in the shared parameters, uplink transmission is performed within the shared COT segment starting from the shared position of COT in the shared parameters, and uplink transmission is interrupted when the shared duration of COT is reached; or in response to a transmission duration greater than the shared duration of COT, it is determined not to share the shared COT segment.
