Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular to a resource processing method, device and storage medium. Background Art

[0002] 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: 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 independently selects the transmission resources.

[0003] Mode 3 and Mode 4 are introduced in the Long Term Evolution-Vehicle to Everything (LTE-V2X) system. In the New Radio-Vehicle to Everything (NR-V2X) system, multiple transmission modes are introduced, including Mode 1 and Mode 2. Among them, Mode 3 and Mode 1 are that the network equipment allocates transmission resources to the terminal equipment, corresponding to the first mode; Mode 4 and Mode 2 are that the terminal equipment independently selects transmission resources, corresponding to the second mode.

[0004] When the first mode and the second mode share a resource pool, since the terminal device does not support simultaneous transmission of two transmission resources, how to avoid transmitting the transmission resources corresponding to the first mode and the transmission resources corresponding to the second mode in the same time slot is an urgent problem to be solved.

[0008] In a third aspect, an embodiment of the present invention provides a resource processing method, including: when a first transmission resource and a second transmission resource are in the same time slot, a terminal device selects a transmission resource for transmitting a service based on at least one of the following:

[0009] The priority of the mode in which the terminal device is located, the service attributes of the service and the priority of the side channel;

[0010] Among them, the modes of the terminal device include: a first mode and a second mode; when the terminal device is in the first mode, the first transmission resource is allocated by the network device; when the terminal device is in the second mode, the second transmission resource is selected autonomously by the terminal device.

[0015] In a sixth aspect, an embodiment of the present invention provides a terminal device, including: a third processing unit, configured so that when the first transmission resource and the second transmission resource are in the same time slot, the terminal device selects a transmission resource for transmitting a service based on at least one of the following:

[0016] The priority of the mode in which the terminal device is located, the service attributes of the service and the priority of the side channel;

[0017] Among them, the modes of the terminal device include: a first mode and a second mode; when the terminal device is in the first mode, the first transmission resource is allocated by the network device; when the terminal device is in the second mode, the second transmission resource is selected autonomously by the terminal device.

[0050] Device to Device (D2D) communication

[0051] 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: the first mode and the second mode. The first mode and the second mode are described below.

[0052] First mode: Figure 2 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.

[0053] Second mode: Figure 3 As shown, the terminal device selects a transmission resource in the resource pool to send data.

[0054] In 3GPP, D2D is divided into the following different stages for research:

[0055] Proximity based Service (ProSe): In Release 12 / 13 (Rel-12 / 13), D2D communication is studied for ProSe scenarios, which mainly targets public safety services.

[0056] 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.

[0057] Wearable devices (FeD2D): In Release 14 (Rel-14), D2D communication is studied for scenarios where wearable devices access the network through mobile phones, mainly for scenarios with low mobility and low power access.

[0058] Listen + Reserve

[0059] For the terminal device to autonomously determine the transmission resources (such as Mode 4 in LTE-V2X), the terminal determines the transmission resources by listening. The process of listening and resource determination is as follows: when a new data packet arrives at time n and a transmission resource needs to be selected for data transmission, the terminal device determines the resource selection window as [n+T1, n+T2], and the terminal device listens in the listening window [n-1000, n-1], and determines the transmission resource in the resource selection window according to the listening result, where T1 <= 4; 20 <= T2 <= 100; Figure 4 As shown:

[0060] The general process of the terminal device selecting transmission resources in the resource selection window is as follows: (For the specific transmission resource selection process, please refer to the operation steps in 3GPP TS36.213 V15.3.0. Here are several main transmission resource selection steps)

[0061] The terminal device regards all available resources in the resource selection window as a set P, and performs an exclusion operation on the resources in the set P:

[0062] 1) If the terminal device has no listening results on some subframes in the resource listening window, for example, if the terminal device sends data on the subframe, then there is no listening result on the subframe, then the resources on the corresponding subframes in the selection window are excluded after K cycles;

[0063] 2) If the terminal device detects a physical sidelink control channel (PSCCH) within the listening window, and the reference signal received power (RSRP) of its corresponding physical sidelink shared channel (PSSCH) is higher than the threshold, and there is a resource conflict between the next transmission resource reserved by the control information and the data to be sent by the terminal device, the terminal device excludes the resource in set P.

[0064] 3) If the number of remaining resources in set P is less than 20% of the total number of resources in the resource selection window, the terminal device will increase the PSSCH-RSRP threshold by 3dB and repeat the above steps 1)-2) until the number of remaining resources in set P is greater than 20% of the total number of resources in the resource selection window.

[0065] 4) The terminal device performs sidelink received signal strength indicator (S-RSSI) detection on the remaining resources in set P, and sorts them according to energy levels, and puts the 20% of resources with the lowest energy (relative to the number of resources in set P) into set Q.

[0066] 5) The terminal device selects a resource from the set Q with equal probability for data transmission.

[0067] The above-mentioned monitoring and resource selection are all performed in the resource pool of PSSCH. In LTE-V2X, the transmission resources of PSSCH and the transmission resources of PSCCH are one-to-one corresponding. Therefore, determining the transmission resources of PSSCH also determines the corresponding transmission resources of PSCCH.

[0068] Configured Grant

[0069] In 3GPP version 15 (Rel-15), in order to reduce the transmission delay of uplink data, a configuration authorization (also called authorization-free) transmission method was introduced, which mainly includes two configuration authorization methods: the first type of configuration authorization (type-1 configured grant) and the second type of configuration authorization (type-2 configured grant).

[0070] 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.

[0071] The second type of configuration authorization: adopts a two-step configuration method. First, the high-level parameter ConfiguredGrantConfig 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.

[0072] 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.

[0073] NR-V2X

[0074] 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.

[0075] In the NR-V2X system, multiple transmission modes are introduced, including Mode 1 and Mode 2, where Mode 1 is that the network device allocates transmission resources to the terminal device (corresponding to the first mode mentioned above), and Mode 2 is that the terminal device selects transmission resources (corresponding to the second mode mentioned above).

[0076] In NR-V2X mode 1, 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.

[0077] In addition, a method of dynamically allocating transmission resources is also introduced in Mode 1 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 2 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 determine the available transmission resource set in the resource pool by listening. When the terminal device selects a transmission resource from the available resource set 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.

[0078] In NR-V2X, terminal devices need to support multiple services, and there may be a situation where a terminal device works in both mode 1 and mode 2. At this time, if the terminal device transmits sideline data in mode 1, the terminal device obtains resource authorization information from the network device and sends the sideline data on the authorized transmission resource. If the terminal device transmits sideline data in mode 2, the terminal device obtains resource pool configuration information according to network configuration information or pre-configuration information, determines the resource pool according to the resource pool configuration information, and autonomously selects transmission resources in the resource pool for sideline data transmission.

[0079] However, if Mode 1 and Mode 2 use independent resource pools, insufficient resource utilization will result. Therefore, Mode 1 and Mode 2 can share a resource pool; that is, the transmission resources in one resource pool can be used for both Mode 1 terminal devices to transmit sideline data and Mode 2 terminal devices to transmit sideline data. When the terminal device supports working in Mode 1 and Mode 2 at the same time, the transmission resources of Mode 1 are allocated by the network device, and the transmission resources of Mode 2 are selected autonomously by the terminal device. However, the terminal device cannot support the simultaneous transmission of two PSSCHs. Therefore, how to avoid the simultaneous transmission of Mode 1 transmission resources and Mode 2 transmission resources of the same terminal device is a problem that needs to be solved. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0080] An optional processing flow of a resource processing method applied to a terminal device provided in an embodiment of the present invention is as follows: Figure 5 As shown, the following steps are included:

[0081] Step S201, the terminal device determines a first transmission resource set within a resource selection window, the first transmission resource set does not include transmission resources within a time slot where a first transmission resource allocated by a network device to the terminal device is located, and the transmission resources within the first transmission resource set are used by the terminal device to send side services.

[0082] In the embodiment of the present invention, the resource selection window is a time interval used by the terminal device to determine the sideline transmission resource.

[0083] In the embodiment of the present invention, the transmission resources in the first transmission resource set are used by the terminal device to send sideline services using mode 2.

[0084] In an embodiment of the present invention, the first transmission resource allocated by the network device to the terminal device is used for the terminal device to send side services using mode 1. In some embodiments, the network device allocates the first transmission resource to the terminal device through DCI or configuration authorization.

[0085] In some embodiments, the process of the terminal device determining the first transmission resource set within the resource selection window may be: the terminal device determines the second transmission resource set from the resource pool within the resource selection window; optionally, the terminal device may determine the second transmission resource set from the resource pool within the resource selection window by listening. The terminal device excludes transmission resources in the second transmission resource set that are in the same time slot as the first transmission resource.

[0086] In other embodiments, after the terminal device determines the second transmission resource set from the resource pool, the terminal device selects the third transmission resource from the second transmission resource set and reserves at least one fourth transmission resource. The fourth transmission resource is a transmission resource corresponding to the third transmission resource in the next transmission cycle. The corresponding transmission resource may refer to the third transmission resource and the fourth transmission resource having the same frequency domain starting position and frequency domain size in their respective transmission cycles. The time domain interval between the third transmission resource and the fourth transmission resource is determined by the transmission cycle of the side data to be transmitted. When the fourth transmission resource and the fifth transmission resource allocated by the network device to the terminal device are in the same time slot, the terminal device excludes the third transmission resource from the second transmission resource set. Furthermore, the terminal device may also exclude the transmission resources in the time slot where the third transmission resource is located from the second transmission resource set.

[0087] In specific implementation, the terminal device determines the first transmission source set, which may occur after the network device configures the first transmission resource for the terminal device. That is, the network device first configures the first transmission resource for the terminal device, and then the terminal device autonomously determines the first transmission resource set. The terminal device determines the first transmission resource set, which may occur before the network device configures the first transmission resource for the terminal device. That is, the terminal device first autonomously determines the first transmission resource set, and then sends the first transmission resource set information to the network device; the network device allocates the first transmission resource to the terminal device according to the first transmission resource set information.

[0088] In the embodiment of the present invention, after executing step S201, the method may further include:

[0089] Step S202: The terminal device sends first information to the network device, where the first information is used to represent information about transmission resources selected by the terminal device for sending sideline services.

[0090] In some embodiments, the terminal device sends the time slot information of the time slot where the transmission resource selected by the terminal device is located to the network device. For example, the first information is the time slot number, which is determined by the system frame number (System Frame Number, SFN) or the direct frame number (Direct Frame Number, DFN) and the time slot sequence number of the time slot in a wireless frame. For example, for a subcarrier spacing of 15kHz, a time slot corresponds to a time length of 1ms, and the time slot number in a wireless frame is [0, 9]. If the system frame number of the time slot is 3, and the time slot sequence number in the wireless frame is 8, then the time slot number determined according to the system frame number and the time slot sequence number is 38, and the terminal device reports 38 to the network device; the network device can then obtain the time slot information of the transmission resource selected by the terminal device.

[0091] The terminal device sends the time slot information of the time slot where the transmission resource selected by itself is located to the network device, thereby preventing the network device from allocating transmission resources on the time slot to the terminal device, thereby preventing the terminal device from transmitting in the same time slot using the transmission resources of mode 1 and the transmission resources of mode 2.

[0092] In the embodiment of the present invention, after executing step S202, the method may further include:

[0093] Step S203: The terminal device sends second information to the network device.

[0094] In some embodiments, the second information is used to determine the time domain interval between the transmission resource selected by the terminal device and the transmission resource reserved by the terminal device. For example, if the terminal device reserves the transmission resource after 100 time slots, the second information reported by the terminal device to the network device is 100. Since the terminal device reports the time slot information of the transmission resource selected by the terminal device to the network device in step S202, the network device can determine the time interval between the next transmission resource reserved by the terminal device and the currently selected transmission resource in combination with the second information, and then the network device can determine the time slot information of the next transmission resource.

[0095] In some other embodiments, the second information is used to determine the service cycle of the sideline service transmitted by the terminal device in the second mode. For example, the second information is the service cycle of the sideline service transmitted by the terminal device in mode 2; if the service cycle is 100ms, the terminal device selects the transmission resource and reserves the transmission resource for the next transmission after 100ms. Therefore, when the terminal device reports the service cycle of the sideline service to the network device, the network device can determine the time interval between the transmission resource reserved by the terminal device and the currently selected transmission resource, and then the network device can determine the time slot information of the next transmission resource.

[0096] In an embodiment of the present invention, the network device determines the time slot information of the selected transmission resource based on the first information reported by the terminal device, and combines the second information to determine the time interval between the reserved previous transmission resource and the current transmission resource, thereby determining the time slot information of the next transmission resource.

[0097] In the embodiment of the present invention, after executing step S203, the method may further include:

[0098] Step S204: The terminal device sends third information to the network device, where the third information is used to determine the number of transmission resources reserved by the terminal device.

[0099] For example, if the terminal device reserves transmission resources for the next four transmission cycles, the third information reported by the terminal device to the network device is 4; the network device can determine, based on the third information, that the number of transmission resources reserved by the terminal device is 4. The terminal device can determine, based on the first information, the second information, and the third information, the time slot information of the transmission resources selected by the terminal device and the time slot information of the reserved transmission resources, thereby preventing the network device from allocating the transmission resources in the time slot corresponding to the time slot information of the terminal device to the terminal device.

[0100] Before executing step S201, or after executing step S202, or after executing step S203, or after executing step S204, the method may further include:

[0101] Step S205: The terminal device receives configuration information sent by the network device, where the configuration information is used to determine the first transmission resource.

[0102] Here, the first transmission resource and the transmission resource selected by the terminal device for sending the sideline service are not in the same time slot; or, the first transmission resource and the transmission resource reserved by the terminal device are not in the same time slot.

[0103] In specific implementation, if step S205 is performed before step S201, the terminal device can determine the first transmission resource after receiving the configuration information sent by the network device. When the terminal device autonomously determines the first transmission resource set, the first transmission resource set does not include the transmission resource in the time slot where the first transmission resource is located.

[0104] If step S205 is executed after step S202, step S203, or step S204, when the network device allocates the first transmission resource to the terminal device, it does not allocate the transmission resources in the time slot of the transmission resources selected by the terminal device in steps S201 to S204 or the reserved time slot.

[0105] The resource processing method for a network device provided in an embodiment of the present invention may include: Figure 6 As shown, including:

[0106] Step S301: A network device receives first information sent by a terminal device, where the first information is used to represent information about transmission resources selected by the terminal device for sending a sideline service.

[0107] In the embodiment of the present invention, the description of the first information is the same as the description of the first information in the above step S202, and will not be repeated here.

[0108] Step S302: The network device allocates a first transmission resource to the terminal device based on the first information.

[0109] In some embodiments, the network device determines the time slot where the transmission resource selected by the terminal device is located based on the first information; the network device does not allocate the transmission resource in the time slot to the terminal device, so that the first transmission resource and the transmission resource selected by the terminal device are not in the same time slot.

[0110] After executing step S302, the method may further include:

[0111] Step S302a: The network device receives the second information sent by the terminal device.

[0112] In the embodiment of the present invention, the second information is used to determine the time domain interval between the transmission resource selected by the terminal device and the transmission resource reserved by the terminal device; or, the second information is used to determine the service period of the sideline service transmitted by the terminal device in the second mode. Wherein, when the terminal device is in the second mode, the sideline transmission resource used by the terminal device is selected autonomously by the terminal device.

[0113] It should be noted that the description of the second information in the embodiment of the present invention is the same as the description of the second information in the above step S203, and will not be repeated here.

[0114] In some embodiments, the network device determines the time slots where the transmission resource selected by the terminal device and the transmission resource reserved by the terminal device are located based on the first information and the second information, respectively; the network device does not allocate the transmission resource in the time slot to the terminal device. In this way, the first transmission resource is not in the same time slot as the transmission resource selected by the terminal device and the reserved transmission resource.

[0115] After executing step S302a, the method may further include:

[0116] Step S302b: The network device receives third information sent by the terminal device, where the third information is used to determine the number of transmission resources reserved by the terminal device.

[0117] It should be noted that the description of the third information in the embodiment of the present invention is the same as the description of the third information in the above step S204, and will not be repeated here.

[0118] After step S302, or step S302a, or step S302b, the method may further include:

[0119] Step S303: The network device sends configuration information to the terminal device, where the configuration information is used to determine the first transmission resource.

[0120] In an embodiment of the present invention, the first transmission resource and the transmission resource selected by the terminal device for sending sideline services are not in the same time slot; or, the first transmission resource and the transmission resource reserved by the terminal device are not in the same time slot.

[0121] After the network device sends the configuration information to the terminal device, the terminal device can determine the first transmission resource; in this way, when the terminal device autonomously selects transmission resources or reserves transmission resources, it can exclude the transmission resources in the time slot where the first transmission resource is located from the available transmission resource set.

[0122] The above embodiments aim to avoid resource conflicts when a terminal device autonomously selects or reserves transmission resources or a network device allocates transmission resources to a terminal device, so as to avoid the situation where the transmission resources selected or reserved by the terminal device and the transmission resources allocated by the network device are not in the same time slot.

[0123] The following describes the processing flow of the resource processing method of an embodiment of the present invention for a scenario in which the transmission resources selected or reserved by the terminal device and the transmission resources allocated by the network device are in the same time slot.

[0124] The processing flow of another resource processing method applied to a terminal device provided by an embodiment of the present invention is as follows: Figure 7As shown, the following steps are included:

[0125] Step S401, when the first transmission resource and the second transmission resource are in the same time slot, the terminal device selects a transmission resource for transmitting the service based on at least one of the priority of the terminal device mode, the service attributes of the service and the priority of the side channel.

[0126] In the embodiment of the present invention, the modes of the terminal device include: the first mode and the second mode; when the terminal device is in the first mode, the first transmission resource is allocated by the network device; when the terminal device is in the second mode, the second transmission resource is selected by the terminal device itself. It can also be understood that the first mode corresponds to the above-mentioned mode 1 in the embodiment of the present invention, and the second mode corresponds to the above-mentioned mode 2 in the embodiment of the present invention.

[0127] In a specific implementation, when the priority of the first mode is higher than the priority of the second mode, the terminal device selects the first transmission resource. The priority of the mode in which the terminal device is located is configured or pre-configured by a network device.

[0128] In the embodiment of the present invention, the service attribute of the service includes any one of the following: service priority, service reliability, service delay and service transmission rate.

[0129] In a specific implementation, the terminal device selects transmission resources corresponding to a service with a high service priority; or, the terminal device selects transmission resources corresponding to a service with a high service reliability; or, the terminal device selects transmission resources corresponding to a service with a short service delay; or, the terminal device selects transmission resources corresponding to a service with a high service transmission rate.

[0130] In an embodiment of the present invention, the sidelink channel includes any two of: PSCCH, PSSCH, Physical Sidelink Feedback Channel (PSFCH) and Physical Sidelink Broadcast Channel (PSBCH). The terminal device selects the transmission resource corresponding to the sidelink channel with a higher priority; wherein the priority of the sidelink channel is configured or pre-configured by the network device. For example, the priority of PSCCH is higher than that of PSSCH, the priority of PSFCH is higher than that of PSCCH or PSSCH, and the priority of PSBCH is higher than that of PSSCH.

[0131] by Figure 8Taking the communication diagram between the terminal devices shown as an example, the first terminal device in the cell is the data transmitter, the second terminal device and the third terminal device are the data receivers, the second terminal device is in the cell, and the third terminal device is outside the cell. The first terminal device uses mode 1 to transmit data with the second terminal device, that is, the first terminal device uses the transmission resources configured by the network device to send sideline services to the second terminal device. The first terminal device uses mode 2 to transmit data with the third terminal device, that is, the first terminal device obtains the resource pool information configured by the network device, autonomously obtains transmission resources in the resource pool by listening, and uses the obtained transmission resources to send sideline data to the third terminal device.

[0132] The resource processing method provided by the embodiment of the present invention is described in detail below for a scenario in which a network device first allocates a first transmission resource to a terminal device, and the terminal device then independently selects a transmission resource. An optional detailed processing flow of the resource processing method provided by the embodiment of the present invention is as follows: Fig. 9 As shown, the following steps are included:

[0133] Step S501: A network device allocates a first transmission resource to a first terminal device.

[0134] In some embodiments, the network device allocates a first transmission resource to the terminal device through downlink control signaling (Downlink Control Information, DCI), and the first transmission resource may include resources for one transmission, or include transmission resources for multiple transmissions (for example, including initial transmission and retransmission of data).

[0135] In other embodiments, the network device allocates the first transmission resource to the first terminal device through a configuration authorization, wherein the configuration authorization may be a type-1 configuration authorization, i.e., the first transmission resource and transmission parameters are configured through RRC signaling; the configuration authorization may also be a type-2 configuration authorization, i.e., part of the sideline transmission parameters are configured through RRC signaling, another part of the transmission parameters and the first transmission resource are configured through DCI signaling, and the configuration authorization is activated or deactivated through DCI. The transmission resources allocated by the network device through the configuration authorization are multiple transmission resources with periodicity.

[0136] Step S502: The first terminal device sends a sideline service using a first transmission resource.

[0137] In the embodiment of the present invention, the first terminal device performs sideline communication with the second terminal device in mode 1; the first terminal device sends a sideline service to the second terminal device using the first transmission resource.

[0138] Step S503: The first terminal device selects a second transmission resource by listening.

[0139] In an embodiment of the present invention, the first terminal device can use the existing listening method to determine the second transmission resource set, exclude the transmission resources in the time slot where the first transmission resource is located in the second transmission resource set, and obtain the first transmission resource set; the first terminal device then selects the second transmission resource in the first transmission resource set, which is used for the first terminal device to communicate sideways with the third terminal device in mode 2.

[0140] In some embodiments, a first terminal device determines a first transmission resource set, such as Fig.10 As shown, the terminal device excludes the transmission resources (such as transmission resource B) reserved by other terminal devices other than the first terminal device from the second transmission resource set within the resource selection window by listening; if there are transmission resources (such as transmission resource C) configured by the network device within the resource selection window, the terminal device excludes all transmission resources on the time slot where the transmission resource C is located from the second transmission resource set; if there is a transmission resource C configured by the network device in time slot n+60, the terminal device excludes all resources on time slot n+60 from the second transmission resource set.

[0141] In some other embodiments, the first terminal device does not have a transmission resource configured by the network device in the resource selection window, but if the first terminal device selects a transmission resource in the resource selection window and reserves one (or the next K) transmission resources, and at least one of the transmission resources reserved by the terminal device and the transmission resource configured by the network device are in the same time slot, then the terminal device excludes the transmission resource in the time slot where the selected transmission resource is located from the first resource set. Another schematic diagram of the first terminal device determining the first transmission resource set, such as Fig.11 As shown; the range of the resource selection window of the terminal device is time slot [n+1, n+100]. There are no transmission resources configured by the network device in the resource selection window, but there is a transmission resource C configured by the network device in time slot n+160. If the terminal device selects transmission resource D on time slot n+60 in the resource selection window, and reserves transmission resource E after 100 time slots, and transmission resource E and transmission resource C are in the same time slot; then the terminal device excludes the time slot where resource D is located, that is, all transmission resources on time slot n+60, from the second resource set.

[0142] In the embodiment of the present invention, after the first terminal device excludes unavailable transmission resources from the second resource set, it continues to select transmission resources using the existing listening mechanism. For example, energy detection is performed on the remaining transmission resources, and the resources with the lowest energy of M% (for example, M=20) are selected as the available first transmission resource set, and a resource is selected with equal probability from the first transmission resource set as the transmission resource for sideline service transmission with the third terminal device in mode 2.

[0143] Step S504: The first terminal device sends a sideline service to the third terminal device on the selected transmission resources.

[0144] It should be noted that in the embodiment of the present invention, there is no order of execution between step S502 and step S503. Step S502 may be executed first and then step S503, or step S503 may be executed first and then step S502. Furthermore, when step S503 is executed first and then step S502, there is no order of execution between step S502 and step S504. Step S502 may be executed first and then step S504, or step S504 may be executed first and then step S502.

[0145] The resource processing method described in the embodiment of the present invention is applicable to the resource determination process of periodic services and non-periodic services in Mode 2. When the first terminal device determines the transmission resource set of Mode 2 by listening, it avoids selecting the transmission resources of Mode 1 that the network device has configured for the first terminal device; thereby avoiding the problem of simultaneous transmission of side services of Mode 2 and Mode 1. Since the transmission resources of Mode 2 exclude the transmission resources of Mode 1 during the listening process, there is no need for the network device to reallocate the transmission resources of Mode 1 to the first terminal device, thereby reducing the signaling overhead between the first terminal device and the network device.

[0146] The following describes in detail the resource processing method provided by the embodiment of the present invention for a scenario in which the terminal device first autonomously selects a transmission resource and the network device then allocates the first transmission resource to the terminal device. Another optional detailed processing flow of the resource processing method provided by the embodiment of the present invention is as follows: Fig.12 As shown, the following steps are included:

[0147] Step S601: The first terminal device selects a second transmission resource by listening.

[0148] It should be noted that, in the embodiment of the present invention, the process of the first terminal device selecting the second transmission resource is the same as the process of the first terminal device selecting the second transmission resource in the above step S503, and will not be repeated here.

[0149] Step S602: The first terminal device sends a sideline service to the third terminal device using the second transmission resource.

[0150] Step S603: The first terminal device sends first information to the network device.

[0151] In the embodiment of the present invention, the network device can determine the time slot information of the time slot where the second transmission resource selected by the first terminal device is located through the first information.

[0152] It should be noted that, in the embodiment of the present invention, the description of the first information is the same as the description of the first information in the above step S203, and will not be repeated here.

[0153] Step S604: The first terminal device sends second information to the network device.

[0154] In the embodiment of the present invention, the network device can determine the time slot information of the time slot where the second transmission resource selected by the first terminal device and a reserved transmission resource are located through the second information.

[0155] It should be noted that, in the embodiment of the present invention, the description of the second information is the same as the description of the second information in the above step S204, and will not be repeated here.

[0156] Step S605: The first terminal device sends third information to the network device.

[0157] In the embodiment of the present invention, the network device can determine the time slot information of the time slots where the second transmission resource selected by the first terminal device and the reserved multiple transmission resources are located through the third information.

[0158] It should be noted that, in the embodiment of the present invention, the description of the third information is the same as the description of the third information in the above step S205, and will not be repeated here.

[0159] Step S606: The network device allocates a first transmission resource to the terminal device based on the first information, the second information and the third information.

[0160] Step S607: The first terminal device sends a sideline service to the second terminal device using the first transmission resource in mode 1.

[0161] In the embodiment of the present invention, before executing step S601, the method may further include: the network device allocates the first terminal device a transmission resource of mode 1. At this time, in step S601, when the first terminal device listens to obtain the second transmission resource, it will exclude all transmission resources in the time slot where the transmission resource allocated by the network device to the terminal device is located.

[0162] The resource processing method described in the embodiment of the present invention is applicable to the process of determining the transmission resources of the periodic service in mode 2. In the case of reserved transmission resources, the terminal device can report the reserved transmission resources to the network device to avoid the network device scheduling the transmission resources selected by the terminal device and the transmission resources in the time slot where the reserved transmission resources are located for the terminal device, and avoid the transmission resources of mode 1 and mode 2 in the same time slot.

[0163] It should be noted that the service in the embodiment of the present invention is equivalent to data; therefore, the terminal device transmitting the sideline service may also be referred to as the terminal device transmitting the sideline data.

[0164] The resource processing method provided in the embodiment of the present invention is described in detail below for the situation where a terminal device needs to perform both mode 1 service transmission and mode 2 service transmission in the same time slot.

[0165] When the first transmission resource and the second transmission resource are in the same time slot, the terminal device selects a transmission resource for transmitting the service based on at least one of the following: the priority of the mode of the terminal device, the service attribute of the service and the priority of the side channel.

[0166] Among them, the modes of the terminal device include: a first mode and a second mode; when the terminal device is in the first mode, the first transmission resource is allocated by the network device; when the terminal device is in the second mode, the second transmission resource is selected autonomously by the terminal device.

[0167] 1) Selecting a transmission resource based on the priority of the mode the terminal device is in. When the priority of the first mode is higher than the priority of the second mode, the terminal device selects a first transmission resource corresponding to the first mode.

[0168] 2) Selecting transmission resources based on service attributes of the service, wherein the service attributes of the service include any one of the following: service priority, service reliability, service delay and service transmission rate.

[0169] For example, mode 1 transmits the first service, and mode 2 transmits the second service. The terminal device determines which transmission resource to select based on the priority of each service. If the priority of the first service is higher than the priority of the second service, the terminal device selects the transmission resource corresponding to the first service and gives up transmitting the second service. If the priority of the first service is lower than the priority of the second service, the terminal device selects the transmission resource corresponding to the second service and gives up transmitting the first service. Alternatively, the terminal device determines which transmission resource to select based on the latency of each service. If the latency requirement of the first service is higher than the latency requirement of the second service, for example, the latency requirement of the first service is 10ms and the latency requirement of the second service is 20ms, the terminal device selects the transmission resource corresponding to the first service and gives up transmitting the second service; if the latency requirement of the first service is lower than the latency requirement of the second service, the terminal device selects the transmission resource corresponding to the second service and gives up transmitting the first service. Alternatively, the terminal device determines which transmission resource to select based on the service transmission rate of each service. If the service transmission rate of the first service is higher than the service transmission rate of the second service, the terminal device selects the transmission resources corresponding to the first service and abandons the transmission of the second service; if the service transmission rate of the first service is lower than the delay requirement of the second service, the terminal device selects the transmission resources corresponding to the second service and abandons the transmission of the first service.

[0170] It should be noted that the service priority is the priority of the logical channel corresponding to the service, and further, the service priority is the highest priority of the logical channel corresponding to the service. If the sidelink control information (Sidelink Control Information, SCI) of the sidelink service or sidelink data to be transmitted carries priority information, the service priority is the priority information carried in the SCI.

[0171] 3) Select transmission resources based on the priority of the side channel.

[0172] The types of side channels include: any two of PSCCH, PSSCH, PSFCH and PSBCH; the priority relationship between the side channels can be pre-configured or network configured. For example, the pre-configured PSFCH transmission priority is higher than PSSCH, and the PSCCH transmission priority is higher than PSSCH. The terminal device determines the side channel in transmission mode 1 or mode 2 according to the transmission priority information between the side channels pre-configured or configured by the network device.

[0173] The embodiment of the present invention solves the problem that when mode 1 and mode 2 are transmitted in the same time slot, a transmission resource is selected by means of the priority of the side channel, service attributes, the mode of the terminal device, etc., to give priority to the transmission of services with higher priority.
