[0002] Device to Device (D2D) communication is based on the sidelink (SL) transmission technology. Unlike the traditional cellular system where communication data is received or sent by the base station, the Internet of Vehicles system adopts D2D communication (i.e., direct device-to-device communication), so it has higher spectrum efficiency and lower transmission latency. For D2D communication, there are two transmission modes: the first mode and the second mode. The first mode is that the network device allocates transmission resources to the terminal device, and the second mode is that the terminal device selects the transmission resources. When the first mode and the second mode share a resource pool, the transmission resources of the terminal in the first mode and the terminal in the second mode may conflict. Summary of the invention

[0051] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below.

[0052] Device to Device (D2D) communication

[0053] D2D communication is based on the sidelink (SL) transmission technology. Different from the traditional cellular system where communication data is received or sent by the base station, the Internet of Vehicles system adopts the D2D communication method (i.e., the device-to-device direct communication method), so it has higher spectrum efficiency and lower transmission delay. For D2D communication, the Third Generation Partnership Project (3GPP) defines two transmission modes: Mode 1 (corresponding to the first mode mentioned above) and Mode 2 (corresponding to the second mode mentioned above). Mode 1 and Mode 2 are described below.

[0054] Mode 1: If Figure 2-1 As shown, the transmission resources of the terminal device are allocated by the base station, and the terminal device sends data on the side link according to the resources allocated by the base station; the base station can allocate resources for a single transmission to the terminal device, and can also allocate resources for semi-static transmission to the terminal device.

[0055] Mode 2: If Figure 2-2 As shown, the terminal device selects a resource in the resource pool to send data.

[0056] In 3GPP, D2D is divided into the following different stages for research:

[0057] Proximity based Service (ProSe): In Release 12 / 13 (Rel-12 / 13), D2D communication is studied for ProSe scenarios, which mainly targets public safety services.

[0058] Vehicle to Everything (V2X): In Rel-14 / 15, D2D communication was studied for V2X scenarios, which mainly targets relatively high-speed vehicle-to-vehicle and vehicle-to-pedestrian communication services.

[0059] Wearable devices (FeD2D): In Release 15 (Rel-15), D2D communication is studied for scenarios where wearable devices access the network through mobile phones, mainly for scenarios with low mobile speeds and low power access.

[0060] Configured Grant

[0061] In 3GPP version 15 (Rel-15), in order to reduce the transmission delay of uplink data, the configuration grant (also called grant-free) transmission mode is introduced, which mainly includes two configuration grant modes: the first type of configuration grant (type-1 configured grant) and the second type of configuration grant (type-2 configured grant).

[0062] The first type of configuration authorization: The network configures transmission resources and transmission parameters for the terminal device through Radio Resource Control (RRC) signaling. The configuration information carried by the RRC signaling includes all transmission resources and transmission parameters including time domain resources, frequency domain resources, demodulation reference signal (DMRS), power control, modulation and coding scheme (MCS), waveform (Waveform), redundancy version (RV), number of repetitions, frequency hopping, number of hybrid automatic repeat request (HARQ) processes, etc. When the terminal device receives the RRC signaling, it can immediately use the configured transmission parameters to perform physical uplink shared channel (PUSCH) transmission on the configured time and frequency resources.

[0063] The second type of configuration authorization: adopts a two-step configuration method. First, the high-level parameter ConfiguredGrantConfit configures the transmission resources and transmission parameters including the period of time-frequency resources, open-loop power control, waveform, redundant version, number of retransmissions, frequency hopping, number of HARQ processes, etc. Then, the downlink control information (Downlink ControlInformation, DCI) activates the PUSCH transmission of the second type of configuration authorization, and simultaneously configures other transmission resources and transmission parameters including time domain resources, frequency domain resources, DMRS, MCS, etc. When the terminal device receives the high-level parameter ConfiguredGrantConfig, it cannot immediately use the resources and parameters configured by the high-level parameter for PUSCH transmission, but must wait until the corresponding activation DCI is received and other resources and transmission parameters are configured before PUSCH transmission can be performed. In addition, the network device can deactivate the PUSCH transmission of the second type of configuration authorization through DCI. When the terminal device receives the deactivated DCI, it can no longer use the transmission resources authorized by the second type of configuration for transmission.

[0064] If the network device allocates a configured authorized transmission resource to the terminal device, when the terminal device has uplink data to transmit, it can directly use the transmission resource for transmission without sending a resource request message (such as a Scheduling Request (SR) message, a Buffer Status Report (BSR) message) to the network to request transmission resources, thereby reducing latency.

[0065] NR-V2X

[0066] In NR-V2X, autonomous driving needs to be supported, which puts higher requirements on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

[0067] In the NR-V2X system, multiple transmission modes are introduced, including Mode 3 and Mode 4. Mode 3 is that the network device allocates transmission resources to the terminal device (corresponding to the first mode mentioned above), and Mode 4 is that the terminal device selects transmission resources (corresponding to the second mode mentioned above).

[0068] In NR-V2X mode 3, a resource allocation method of configuration authorization is also introduced in the sidelink transmission, that is, the network device allocates sidelink transmission resources to the terminal device by means of configuration authorization. When the terminal device is allocated with the transmission resource of configuration authorization, the terminal device can transmit the sidelink data on the transmission resource without sending SR / BSR messages to the network to reapply for resources, thereby reducing the transmission delay. In the transmission mode of configuration authorization, the network device allocates semi-static transmission resources to the terminal device. For the first type of configuration authorization, the network device configures the configuration authorization transmission resources through RRC signaling, and the terminal device can transmit the sidelink data on the configuration authorization transmission resources. In addition, the network device can reconfigure the configuration authorization transmission resources through RRC signaling. For the second type of configuration authorization, the network device configures some transmission parameters through RRC signaling, configures transmission resources and another part of transmission parameters through DCI, and can activate or deactivate the configuration authorization through DCI. When the configuration authorization is activated, the terminal device can use the transmission resources of the configuration authorization to transmit sidelink data. When the configuration authorization is deactivated, the terminal device can no longer use the transmission resources of the configuration authorization for transmission.

[0069] In addition, a method of dynamically allocating transmission resources is also introduced in Mode 3 of NR-V2X. When the terminal device has side data to send, it sends a resource request to the network. The network device allocates side transmission resources to the terminal device through DCI, and the terminal device uses the transmission resources for side data transmission. In Mode 4 of NR-V2X, the terminal device autonomously selects transmission resources from the resource pool allocated or preconfigured by the network device. The terminal device can obtain a set of available resources in the resource pool by listening. When the terminal device selects a transmission resource from the set of available resources for data transmission, for periodic transmission services, the terminal device can reserve the transmission resources for the next transmission to prevent other users from preempting the resources. For non-periodic transmission services, the terminal device does not reserve transmission resources.

[0070] In NR-V2X, when mode 3 and mode 4 can share a resource pool, if the network device allocates transmission resources to the terminal device 1 of mode 3, such as the transmission resources that are configured and authorized, the terminal device 1 can send side data on the transmission resources. If the terminal device 1 uses the transmission resources to transmit periodic side data, the subsequent transmission resources will be reserved. If the terminal device 1 uses the transmission resources to transmit non-periodic side data, the subsequent transmission resources will not be reserved. At this time, other terminal devices, such as terminal devices of mode 4, may determine that the transmission resources that are configured and authorized are available transmission resources when acquiring the available resource set by listening, and select the transmission resources for side data transmission, while the network device does not know that the transmission resources have been occupied by the terminal device of mode 4, and the terminal device 1 will not listen to determine whether the resources are used by other terminal devices, thereby causing resource conflicts. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0071] Figure 3 Schematic diagram of the resource sharing method provided in the embodiment of the present application Figure 1 ,like Figure 3 As shown, the resource sharing method includes the following steps:

[0072] Step 301: A first terminal device receives first configuration information sent by a network device, where the first configuration information is used to configure a first side transmission resource.

[0073] In the embodiment of the present application, the first terminal device can be any device that can communicate with the network, such as a mobile phone, a tablet computer, a vehicle-mounted terminal, a wearable device, a notebook, etc.

[0074] In an embodiment of the present application, the network device may be a base station, such as a gNB, an eNB, etc.

[0075] In the embodiment of the present application, the network device allocates a first side transmission resource to the first terminal device, and sends first configuration information for configuring the first side transmission resource to the first terminal device. Here, since the transmission resource of the first terminal device is allocated by the network device, the transmission mode of the first terminal device is the first mode (which may be mode 1 or mode 3), and the resource allocation method of the first mode refers to the network device allocating transmission resources to the terminal device.

[0076] In an optional implementation, the first side transmission resource may be configured using a configuration-authorized resource allocation method, that is, the network device allocates the first side transmission resource to the terminal device using a configuration-authorized method (such as a first-type configuration-authorized method or a second-type configuration-authorized method).

[0077] In an optional implementation, the first side transmission resource may be configured in a dynamically scheduled resource allocation manner, that is, the network device allocates the first side transmission resource to the terminal device via DCI. In an optional implementation, the network device allocates one or more first side transmission resources to the first terminal device.

[0078] Step 302: The first terminal device sends first indication information on the sidelink, where the first indication information is used to determine the first sidelink transmission resource.

[0079] In an embodiment of the present application, after other terminal devices (such as a second terminal device) receive the first indication information, they can determine the first side transmission resource allocated by the network device to the first terminal device based on the first indication information, thereby avoiding using the first side transmission resource.

[0080] In an embodiment of the present application, the first indication information is used to indicate the time domain information and / or frequency domain information of the first sideline transmission resource.

[0081] In an optional implementation, the first terminal device sends the first indication information by broadcasting on a side link.

[0082] For example: Refer to Figure 4 The base station allocates a first side transmission resource (such as a configured authorized transmission resource) to the first terminal device, and sends first configuration information for configuring the first side transmission resource to the first terminal device via a downlink. After the first terminal device obtains the first configuration information, it sends first indication information for determining the first side transmission resource via the side link. Optionally, the first terminal device can send the first indication information to other users (such as the second terminal device) by broadcasting.

[0083] In an embodiment of the present application, the first indication information is carried in sidelink control information (Sidelink Control Information, SCI) or a physical sidelink shared channel (Physical Sidelink Control Channel, PSSCH).

[0084] In an optional implementation manner, the first indication information is carried by the SCI. Further, the SCI also carries at least one of the following information:

[0085] second indication information, where the second indication information is used to determine a time interval between two adjacent first side transmission resources or a period of the first side transmission resource;

[0086] third indication information, where the third indication information is used to determine information of a bandwidth part (Band Width Part, BWP) where the first sidelink transmission resource is located and / or information of a resource pool;

[0087] Fourth indication information, the fourth indication information is used to indicate that the first side transmission resource is a transmission resource allocated by a network device or that the first terminal device operates in a first mode; wherein, when the first terminal device operates in the first mode, the side transmission resource used by the first terminal device is a side transmission resource allocated by a network device.

[0088] For example: the SCI includes an information field for carrying fourth indication information, and the information field is, for example, 1 bit. When the bit value is a first value (for example, the first value is 1), it indicates that the first sideline transmission resource indicated by the SCI, or the first sideline transmission resource indicated in the PSSCH corresponding to the SCI is a transmission resource allocated by the network device (that is, a transmission resource of the first mode).

[0089] For example: the SCI includes an information field for carrying fourth indication information, and the information field is, for example, 1 bit. When the value of the bit is a first value (for example, the first value is 1), it indicates that the first terminal device is operating in the first mode, wherein, when the first terminal device is operating in the first mode, the sideline transmission resources used by the first terminal device are the sideline transmission resources allocated by the network device; when the value of the bit is a second value (for example, the second value is 0), it indicates that the first terminal device is operating in the second mode, wherein, when the first terminal device is operating in the second mode, the sideline transmission resources used by the first terminal device are the transmission resources autonomously selected by the first terminal device.

[0090] In an optional implementation manner, the first indication information is carried by PSSCH. Further, the PSSCH also carries at least one of the following information:

[0091] second indication information, where the second indication information is used to determine a time interval between two adjacent first side transmission resources, or a period of the first side transmission resource;

[0092] third indication information, where the third indication information is used to determine information about a bandwidth part BWP and / or information about a resource pool where the first sideline transmission resource is located;

[0093] Fourth indication information, the fourth indication information is used to indicate that the first side transmission resource is a transmission resource allocated by a network device or that the first terminal device operates in a first mode; wherein, when the first terminal device operates in the first mode, the side transmission resource used by the first terminal device is a side transmission resource allocated by a network device.

[0094] Optionally, the PSSCH may carry the above one or more indication information in the form of a media access control (MAC) control element (CE).

[0095] It should be noted that the first indication information, the second indication information, the third indication information, and the fourth indication information may be carried through the SCI, or carried through the PSSCH corresponding to the SCI, or part of the indication information may be carried through the SCI, and the rest of the indication information may be carried through the PSSCH. For example, the fourth indication information may be carried through the SCI, and the rest of the indication information may be carried through the PSSCH; for another example, the first indication information and the fourth indication information may be carried through the SCI, and the second indication information and the third indication information may be carried through the PSSCH.

[0096] In the embodiment of the present application, the SCI is used to schedule the PSSCH. Specifically, the SCI is used to indicate the transmission parameters and transmission resources of the PSSCH.

[0097] In an embodiment of the present application, the first terminal device obtains a second side transmission resource, and sends the first indication information on the second side transmission resource.

[0098] Here, the first terminal device may obtain the second sideline transmission resource in any of the following ways:

[0099] Method 1: The first terminal device receives second configuration information sent by a network device, where the second configuration information is used to indicate the second side transmission resource.

[0100] Here, the second sideline transmission resource belongs to the transmission resource of the first mode (which may be mode 1 or mode 3).

[0101] In an optional implementation, the first configuration information and the second configuration information are the same configuration information.

[0102] For example, the network configures an authorized side transmission resource, i.e., a first side transmission resource, for a terminal device through first configuration information. The first side transmission resource includes multiple transmission resources. The terminal device selects one of the transmission resources (i.e., the second side transmission resource) and sends a first indication information. The first indication information is used to indicate the first side transmission resource configured by the network.

[0103] In an optional implementation manner, the first configuration information and the second configuration information are different configuration information.

[0104] For example, the network configures an authorized sideline transmission resource, i.e., the first sideline transmission resource, for the terminal device through the first configuration information, and the network allocates the second sideline transmission resource to the terminal device through DCI (i.e., the second configuration information). The terminal device sends the first indication information on the second sideline transmission resource, and the first indication information is used to indicate the first sideline transmission resource configured by the network.

[0105] Method 2: The first terminal device obtains resource pool configuration information, and determines the first resource pool according to the resource pool configuration information; the first terminal device determines the second side transmission resource in the first resource pool by listening or randomly selecting.

[0106] Here, the resource pool configuration information may be configured by the network device or may be pre-configured.

[0107] Here, the second sideline transmission resource belongs to a transmission resource of a second mode (which may be mode 2 or mode 4).

[0108] According to the technical solution of the embodiment of the present application, the first terminal device of the first mode sends the first sideline transmission resource allocated by the network device through the sideline link, so that other terminal devices (such as the terminal device of the second mode) obtain the first sideline transmission resource of the terminal device of the first mode, thereby avoiding the use of the first sideline transmission resource, thereby avoiding interference between the terminal device of the second mode and the terminal device of the first mode.

[0109] Figure 5 A second flow chart of the resource sharing method provided in the embodiment of the present application is as follows: Figure 5 As shown, the resource sharing method includes the following steps:

[0110] Step 501: A first terminal device receives first configuration information sent by a network device, where the first configuration information is used to configure a first side transmission resource.

[0111] In the embodiment of the present application, the first terminal device can be any device that can communicate with the network, such as a mobile phone, a tablet computer, a vehicle-mounted terminal, a wearable device, a notebook, etc.

[0112] In an embodiment of the present application, the network device may be a base station, such as a gNB, an eNB, etc.

[0113] In the embodiment of the present application, the network device allocates a first side transmission resource to the first terminal device, and sends first configuration information for configuring the first side transmission resource to the first terminal device. Here, since the transmission resource of the first terminal device is allocated by the network device, the transmission mode of the first terminal device is the first mode (which may be mode 1 or mode 3), and the resource allocation method of the first mode refers to the network device allocating transmission resources to the terminal device.

[0114] In an optional implementation, the first side transmission resource may be configured using a configuration-authorized resource allocation method, that is, the network device allocates the first side transmission resource to the terminal device using a configuration-authorized method (such as a first-type configuration-authorized method or a second-type configuration-authorized method).

[0115] In an optional implementation, the first sideline transmission resource may be configured using a dynamically scheduled resource allocation method, that is, the network device allocates the first sideline transmission resource to the terminal device via DCI.

[0116] In an optional implementation, the network device allocates one or more first sideline transmission resources to the first terminal device.

[0117] Step 502: The first terminal device sends resource reservation indication information on the sidelink, where the resource reservation indication information is used to instruct the first terminal device to reserve the first sidelink transmission resource.

[0118] In the existing mechanism, such as the LTE-V2X system, if the terminal device transmits periodic services, it will indicate that resources are reserved for the next transmission. If it transmits non-periodic services, resources are not reserved for the next transmission. In the embodiment of the present application, when the first terminal device sends sidelink data on the sidelink, the sidelink data corresponds to periodic services or non-periodic services, and resource reservation indication information is sent on the sidelink, and the resource reservation indication information is used to indicate that resources are reserved for the next transmission.

[0119] Furthermore, in the LTE-V2X system, the terminal device determines the resources reserved for the next transmission based on the side data to be transmitted. For example, if the data to be transmitted is a periodic service of 100ms, the terminal device reserves the transmission resources after 100ms, and if the data to be transmitted is a periodic service of 500ms, the terminal device reserves the transmission resources after 500ms. In an embodiment of the present application, the first terminal device determines the next reserved transmission resources based on the configuration information of the first side transmission resources sent by the network, rather than based on the side data to be transmitted by the terminal. For example, the period of the first side transmission resources configured by the network is 50ms, that is, there is a first side transmission resource every 50ms, and the side data to be transmitted by the first terminal device is a periodic service of 100ms, then the resource reservation indication information of the first terminal device indicates to reserve the transmission resources after 50ms. For another example, the period of the first side transmission resource configured by the network is 50ms, that is, there is a first side transmission resource every 50ms, and the side data to be transmitted by the first terminal device is a non-periodic service, then the resource reservation indication information of the first terminal device indicates the reservation of transmission resources after 50ms.

[0120] It should be noted that the next transmission here refers to the transmission of the next new transmission block.

[0121] (Transmission Block, TB), rather than retransmitting a data block.

[0122] In the embodiment of the present application, the resource reservation indication information is carried in the SCI. Further, the SCI also carries at least one of the following information:

[0123] Fifth indication information, the fifth indication information is used to indicate that the first side transmission resource is a transmission resource allocated by a network device or that the first terminal device operates in a first mode; wherein, when the first terminal device operates in the first mode, the side transmission resource used by the first terminal device is a side transmission resource allocated by a network device;

[0124] Sixth indication information, the sixth indication information is used to determine a time interval, wherein the time interval is a time interval between the first sideline transmission resource reserved and a transmission resource for transmitting the resource reservation indication information;

[0125] The seventh indication information is used to determine the reservation times (or the reserved number) of the first side transmission resource.

[0126] In an optional implementation, the SCI is used to indicate transmission parameters and transmission resources of a PSSCH, and the PSSCH is used to transmit sideline data of a non-periodic service, that is, the sideline data transmitted in the PSSCH scheduled by the SCI corresponds to the non-periodic service.

[0127] In an optional implementation, the SCI is used to indicate transmission parameters and transmission resources of a PSSCH, and the PSSCH is used to transmit side data of a periodic service, that is, the side data transmitted in the PSSCH scheduled by the SCI corresponds to the periodic service.

[0128] In one example, a network device allocates a first side-line transmission resource to a first terminal device. The first side-line transmission resource may be a configured authorized transmission resource. The first side-line transmission resource is a set of periodic transmission resources. When the first terminal device uses the first side-line transmission resource to transmit side-line data, whether it is transmitting periodic services or non-periodic services, resource reservation indication information is carried in the SCI. Subsequent transmission resources are reserved through the resource reservation indication information, thereby preventing other users, such as users in the second mode (which may be mode 2 or mode 4), from preempting the transmission resources.

[0129] In one example, the SCI includes an information field for carrying resource reservation indication information, and the information field is, for example, 1 bit. When the value of the bit is a first value (for example, the first value is 1), it indicates that the first terminal device reserves the first side transmission resource; when the value of the bit is a second value (for example, the second value is 0), it indicates that the first terminal device does not reserve the first side transmission resource.

[0130] In one example, the SCI includes an information field for carrying fifth indication information, and the information field is, for example, 1 bit. When the value of the bit is a first value (for example, the first value is 1), it indicates that the first sideline transmission resource indicated by the SCI, or the first sideline transmission resource indicated in the PSSCH corresponding to the SCI is a transmission resource allocated by a network device (that is, a transmission resource of a first mode). Alternatively, when the value of the bit is a first value (for example, the first value is 1), it indicates that the first terminal device operates in a first mode, wherein, when the first terminal device operates in the first mode, the sideline transmission resource used by the first terminal device is a sideline transmission resource allocated by the network device; when the value of the bit is a second value (for example, the second value is 0), it indicates that the first terminal device operates in a second mode, wherein, when the first terminal device operates in the second mode, the sideline transmission resource used by the first terminal device is a transmission resource autonomously selected by the first terminal device.

[0131] In one example, the SCI includes an information field for carrying the sixth indication information, and the indication field is used to determine the time interval between the reserved first side transmission resources and the transmission resources for transmitting the resource reservation indication information. For example, the time interval that can be determined by the value of the information field is {10, 20, 50, 100, 200, 500, 1000) ms, etc.

[0132] In one example, the SCI includes an information field for carrying the seventh indication information, and the indication field is used to indicate how many times (or how many) the first side transmission resources are reserved by the first terminal device, or how many cycles the first side transmission resources are reserved. For example, the value range of the number of reservations indicated by the information field is [0, 7], where a value of 0 indicates that no first side transmission resources are reserved, a value of 1 indicates that one first side transmission resource is reserved, a value of 2 indicates that two first side transmission resources are reserved, and so on.

[0133] For example, the SCI includes an information field for carrying the sixth indication information, and the indication field indicates that the time interval is 100ms. In addition, the SCI includes an information field for carrying the seventh indication information, and the value of the indication field is 5, indicating that the first side transmission resources for 5 transmission cycles are reserved. If the terminal device sends the SCI in time slot n, it means that the terminal device has reserved transmission resources for time slots n+100, n+200, n+300, n+400, and n+500.

[0134] It should be noted that if the first terminal device indicates in the SCI to reserve the first sideline transmission resource, when the first terminal device has no data transmission on a certain first sideline transmission resource, it is impossible to reserve the first sideline transmission resource for the next cycle. At this time, other users may preempt the first sideline transmission resource, thereby causing resource conflict. Figure 6 As shown, when the first terminal device transmits data on each transmission resource, it reserves resources for the next transmission. However, if for non-periodic transmission services, the first terminal device does not have side data transmission on each transmission resource, for example, there is no side data transmission in time slot n+20, so the transmission resource n+30 cannot be reserved. At this time, other terminal devices may preempt the transmission resource n+30.

[0135] In the embodiment of the present application, by indicating the number of reservations, even if the first terminal device does not transmit data on a first side transmission resource, the first side transmission resource can be reserved according to the number of reservations indicated in the previous SCI. Figure 7As shown, the network device configures a transmission resource for the first terminal device. The transmission resource may be a configured authorized transmission resource with a period of 10 time slots, that is, there is one transmission resource in every 10 time slots. When the first terminal device has data transmission in time slot n, the SCI carries seventh indication information N for determining the number of reservations, for example, N=3, and carries the seventh indication information each time data is transmitted. For example, there is data transmission in time slots n, n+10, and n+30, and the SCI carries the seventh indication information. The SCI transmitted in time slot n+30 can reserve transmission resources in the next three cycles, namely, transmission resources for n+40, n+50, and n+60. However, if there is no data transmission in n+60, there is no way to reserve subsequent transmission resources, such as transmission resources for time slot n+70. At this time, other users may preempt the transmission resources. Therefore, side data is also transmitted in time slot n+60, such as random bits or redundant bits, so that transmission resources for the next three cycles (i.e., n+70, n+80, and n+90) can be reserved.

[0136] In an optional embodiment, the first terminal device receives third configuration information or first control information sent by the network device, wherein the third configuration information is used to configure a third side transmission resource; the first control information is used to indicate deactivation of the first side transmission resource; the first terminal device sends ninth indication information, and the ninth indication information is used to indicate that the first terminal device does not reserve resources.

[0137] Here, when the first terminal device receives the resource reconfiguration information (i.e., the third configuration information) sent by the network device, or receives the deactivation information (i.e., the first control information) sent by the network device, the SCI sent by the first terminal device carries the indication information of not reserving the first side transmission resource, so that the first side transmission resource can be released. Figure 8 As shown, the resource reservation indication information sent by the terminal device in time slot n+30 indicates that transmission resources are reserved for the next three cycles (i.e., n+40, n+50, and n+60). If the first terminal device receives resource reconfiguration information or deactivation information sent by the network device during the transmission process, for example, a DCI deactivation configuration authorization is received in time slot n+43, the first terminal device sends sidelink data in time slot n+50 and does not reserve transmission resources, thereby releasing the transmission resources for the next cycle.

[0138] In an optional implementation manner, the number of reservations for the first sideline transmission resource is preconfigured or configured by the network device.

[0139] For example: the number of times N that the first side transmission resource is reserved is a fixed value, which can be pre-configured or configured by the network device. At this time, the first terminal device sends resource reservation indication information in the SCI. For example, the resource reservation indication information can be 1 bit, and the value of the bit is used to indicate whether the first terminal device reserves the subsequent transmission resources. If reserved, the transmission resources are reserved N times. Figure 8 As shown, if the network device configures the number of reservations N=3, a 1-bit indication field is included in the SCI to indicate whether to reserve the following transmission resources. When the first terminal device sends the side data, if it needs to reserve the following transmission resources, the bit in the SCI is set to 1, indicating that the following transmission resources are reserved, and reserved 3 times, such as time slots n, n+10, and n+30. If the first terminal device does not need to reserve the following transmission resources, such as time slot n+50, the bit in the SCI is set to 0.

[0140] In an optional implementation, when the first side transmission resource configured in the first configuration information is a configuration authorized transmission resource, the resource reservation indication information further includes: eighth indication information, the eighth indication information is used to determine the period of the first side transmission resource. Alternatively, the time interval determined by the sixth indication information is equal to the period of the first side transmission resource.

[0141] Here, the network device configures an authorized transmission resource for the first terminal device, and the transmission resource is periodic, so the first terminal device carries the period information of the transmission resource in the SCI, or, if the SCI carries sixth indication information for determining a time interval, the time interval is the time interval between the reserved first side transmission resource and the transmission resource for transmitting the resource reservation indication information, then the time interval is equal to the period of the transmission resource.

[0142] In one example: the network device configures authorized transmission resources for the first terminal device, and configures the period information of the transmission resources, for example, 50ms, that is, every 50ms of transmission resources can be used by the first terminal device for side data transmission. When the first terminal device uses the transmission resources for side data transmission, whether it is transmitting periodic services or non-periodic services, the first terminal device carries the sixth indication information or the eighth indication information in the SCI, that is, 50ms, to indicate that the first terminal device has reserved the same transmission resources after 50ms. Furthermore, even if the first terminal device transmits periodic services, but the period of the service is not 50ms, for example, 100ms or 200ms, the sixth indication information or the eighth indication information carried by the first terminal device in the SCI also indicates 50ms.

[0143] In an optional implementation manner, when the first side transmission resource configured in the first configuration information is a dynamically allocated transmission resource, the first configuration information is used to configure multiple first side transmission resources, and the time interval determined by the sixth indication information is determined according to the multiple first side transmission resources configured in the first configuration information. Here, the time intervals between two adjacent first side transmission resources in the multiple first side transmission resources are all the same, all different, or partially different.

[0144] Here, the transmission resources allocated by the network device to the first terminal device are dynamically allocated transmission resources. For example, the network device allocates multiple transmission resources to the first terminal device through DCI, then multiple transmission resources will be indicated in the DCI. When the first terminal device uses one of the transmission resources to transmit sidelink data, whether it is periodic or non-periodic sidelink data, resource reservation indication information will be carried in the SCI to indicate the reservation of subsequent transmission resources, and the SCI will also carry indication information of the time interval between the next transmission resource and the current transmission resource.

[0145] In one example: the network device allocates four transmission resources to the first terminal device through DCI. The frequency domain resources of these four transmission resources are the same, and the time intervals between two adjacent transmission resources can be the same or different. For example, the time intervals between two adjacent transmission resources in the four transmission resources are 10ms, 15ms and 20ms respectively; when the first terminal device uses the first transmission resource for transmission, 10ms is indicated in the SCI to reserve the second transmission resource; when the second transmission resource is used for transmission, 15ms is indicated in the SCI to reserve the third transmission resource; when the third transmission resource is used for transmission, 20ms is indicated in the SCI to reserve the fourth transmission; when the fourth transmission resource is used for transmission, the SCI does not reserve the next transmission resource. If the time intervals between two adjacent transmission resources in the four transmission resources are both 20ms; when the first terminal device uses the first three transmission resources for transmission, 20ms is indicated in the SCI to reserve the resources for the next transmission; when the fourth transmission resource is used for transmission, the SCI does not reserve the next transmission resource.

[0146] In the above solution, if the first sideline transmission resource allocated by the network device to the first terminal device has been occupied by other users, the following method can be used to coordinate resources.

[0147] ●The first terminal device detects that the first side transmission resource is occupied or reserved by the second terminal device, and sends a tenth indication information and / or a first resource request message to the network device; wherein the tenth indication information is used to indicate that the first side transmission resource is occupied or reserved, and the first resource request message is used to request the network device to reconfigure the side transmission resource for the first terminal device.

[0148] Optionally, the first terminal device determines an available resource set and reports the available resource set to the network device, wherein the available resource set is used to assist the network device in reconfiguring sideline transmission resources for the first terminal. Further, the first terminal device determines the available resource set by resource monitoring.

[0149] like Fig. 9 As shown, 1. The base station allocates transmission resources to UE1; 2. UE1 determines whether the transmission resources are occupied; 3. If the transmission resources are not occupied, the transmission resources are used to transmit data; 4. If the transmission resources are occupied, UE1 initiates a resource request to the base station; 5. UE1 reports the available resource set to the base station; 6. The base station reallocates transmission resources for UE1; 7. UE1 uses the reallocated transmission resources to transmit data.

[0150] ●If the first terminal device detects that other users have occupied or reserved the first side-line transmission resource allocated by the network device for the first terminal device, the first terminal device still uses the first side-line transmission resource allocated by the network for data transmission. If other terminal devices (such as mode 2 or mode 4 terminal devices) detect that the first terminal device has used the first side-line transmission resource and has reserved subsequent transmission resources, the other terminal devices avoid continuing to use the first side-line transmission resource.

[0151] like Fig.10 As shown, the first terminal device uses time slots n, n+10, n+30, and n+60 to transmit data. If the second terminal device uses time slot n to transmit data, and the reserved period is 20ms, the second terminal device will reserve transmission resources for time slots n+20, n+40, and n+60. Although the data of the two terminal devices conflict in time slot n, the second terminal device does not send data in time slots n+10 or n+30, while the first terminal device sends data. Therefore, the second terminal device can receive the data of the first terminal device, thereby avoiding the use of the transmission resources reserved by the first terminal device. For example, when the second terminal device detects that the first terminal device has sent data in time slot n+10 and reserves the transmission resources for the next three periods, the second terminal device will give up continuing to use the transmission resources, thereby avoiding interference with the first terminal device.

[0152] The first terminal device detects that the first side transmission resource is occupied or reserved by the second terminal device, obtains a fourth side transmission resource, and sends the resource reservation indication information on the fourth side transmission resource. After receiving the resource reservation indication information sent by the first terminal device, the second terminal device abandons the use of the first side transmission resource of the first terminal device.

[0153] Optionally, the first terminal device receives fourth configuration information sent by the network device, and the fourth configuration information is used to indicate the fourth side transmission resource. Further, the first terminal device sends a second resource request message to the network device, and receives fourth configuration information sent by the network device, and the fourth configuration information is used to indicate the fourth side transmission resource. The fourth side transmission resource is a transmission resource different from the first side transmission resource.

[0154] Optionally, the first terminal device obtains resource pool configuration information, and determines the second resource pool according to the resource pool configuration information; the first terminal device determines the fourth side transmission resource in the second resource pool by listening or randomly selecting.

[0155] In an example: Fig.11 As shown, the network device allocates a configured authorized transmission resource with a period of 10ms to the first terminal device. The second terminal device uses the same transmission resource to transmit side data in time slot n, and reserves transmission resources after 20ms. Therefore, the transmission resources that the second terminal device expects to use are the transmission resources in time slots n+20, n+40, and n+60. When the first terminal device detects through listening that the second terminal device uses the transmission resources in time slot n, the first terminal device determines the second resource pool according to the resource pool information configured by the network, and obtains the fourth side transmission resource in the resource pool by listening, for example, obtains a transmission resource on time slot n+15, and the SCI transmitted on the transmission resource carries resource reservation indication information in the SCI, which is used to indicate the reservation of transmission resources in time slot n+20. The second terminal device can detect the SCI sent by the first terminal device, thereby avoiding using time slot n+20 to transmit side data. Furthermore, the first terminal device transmits data on the transmission resources in time slots n+20 and n+50, and reserves transmission resources for the next three cycles. The second terminal device detects that the first terminal device has reserved transmission resources, and can avoid using transmission resources n+40 and n+60.

[0156] According to the technical solution of the embodiment of the present application, the first terminal device in the first mode sends sidelink data on the sidelink, and whether it is a periodic service or a non-periodic service, it indicates to reserve the following transmission resources. When other terminal devices (such as terminal devices in the second mode) detect the sidelink data of the first terminal device in the first mode, they can learn the transmission resources reserved by the first terminal device in the first mode, thereby avoiding using the transmission resources reserved by the first terminal device. Furthermore, when other terminal devices (such as terminal devices in the second mode) use or reserve the transmission resources of the first terminal device, the first terminal device can send an indication message to the network device to indicate the reallocation of the transmission resources, or send a resource reservation indication message on the transmission resources acquired by interception, thereby avoiding interference between the terminal device in the second mode and the terminal device in the first mode.
