Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technology, and in particular to a resource configuration method and device. Background Art
[0002] With the development of wireless communication technology, people's demand for high data rate and user experience is growing. At the same time, people's demand for proximity services to understand and communicate with people or things around them is gradually increasing. Therefore, device-to-device (D2D) technology came into being. The application of D2D technology can reduce the burden of cellular networks, reduce the battery power consumption of user equipment, increase data rates, and meet the needs of proximity services. D2D technology allows multiple user equipment (UE) supporting D2D functions to conduct direct discovery and direct communication with or without network infrastructure. In view of the characteristics and advantages of D2D technology, the application scenario of Internet of Vehicles based on D2D technology has been proposed, but due to security considerations, the latency requirements in this scenario are very high, which cannot be achieved by existing D2D technology.
[0003] Therefore, under the Long Term Evolution (LTE) technology network proposed by the 3rd Generation Partnership Project (3GPP), the vehicle-to-everything (V2X) vehicle networking technology was proposed. V2X communication refers to the communication between vehicles and anything in the outside world, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-pedestrian (V2P). V2X communication is aimed at high-speed equipment represented by vehicles, and is the basic technology and key technology for applications in scenarios with very high requirements for communication latency in the future, such as smart cars, autonomous driving, and intelligent transportation systems. LTE V2X communication is the sidelink communication (SL) technology in LTE version 12. This technology can support communication scenarios with and without network coverage. Its resource allocation method can adopt the network access device scheduling mode, such as the Evolved Universal Terrestrial Radio Access Network Node B (E-UTRAN Node B, eNB) scheduling mode and UE self-selection mode. Based on V2X technology, users can broadcast or multicast some of their own information, such as location, speed, intention (turning, reversing), etc. to surrounding users periodically / non-periodically, and also receive information from surrounding users.
[0004] As user needs diversify, scenarios where high-speed devices are operated in groups have been proposed. The so-called group is a group of users operating together in a relatively close physical distance. Users need to share information, such as speed, direction, and next actions such as acceleration and deceleration. The group should have a leader who is responsible for the management and maintenance of the group and can update the traffic conditions around the group in real time. In the existing technology, for the application scenarios of high-speed devices such as vehicles, the resource allocation is for a single user, and it is impossible to achieve scenarios for groups.

It should be noted that the public resource indication information and a part of the dedicated resource indication information may refer to one of the two as a part, that is, the public resource indication information or the dedicated resource indication information is sent through the physical side link control channel PSCCH; it may also refer to a part of the public resource indication information and / or a part of the dedicated resource indication information; it may also be a part of the public resource indication information and the dedicated resource indication information, or a part of the public resource indication information and / or the dedicated resource indication information.

[0086] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present application will be further described in detail in the form of embodiments in conjunction with the accompanying drawings. The detailed description proposes various embodiments of devices and / or processes by using block diagrams, flow charts and / or examples. Since these block diagrams, flow charts and / or examples contain one or more functions and / or operations, those skilled in the art will understand that each function and / or operation in these block diagrams, flow charts or examples can be implemented individually and / or together by a number of hardware, software, firmware or any combination thereof.
[0087] In this application, "multiple" refers to two or more. The term "and / or" in this application is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the previous and next associated objects are in an "or" relationship. The terms "first", "second", "third", "fourth", etc. in this application are intended to distinguish different objects, and do not limit the order of the different objects.
[0088] All "terminals" mentioned in this application may refer to mobile devices in some cases, such as mobile phones, personal digital assistants, handheld or laptop computers, and similar devices with telecommunication capabilities, and may also be wearable devices or vehicle-mounted devices, etc., and include terminals in future 5G networks or terminals in future evolved PLMN networks, etc. Such a terminal may include a device and its associated removable storage module (for example, but not limited to: a universal integrated circuit card (UICC) including a subscriber identification module (Subscriber Identification Module, referred to as SIM) application, a universal subscriber identification module (Universal Subscriber Identification Module, referred to as USIM) application, or a removable user identification module (Removable User Identity Module, referred to as R-UIM) application). Alternatively, such a terminal may include the device itself without such a module. In other cases, the term "terminal" may refer to a device with similar capabilities but not portable, such as a desktop computer, a set-top box, or a network device. The term "terminal" may also refer to any hardware or software component that can terminate a user's communication session. In addition, "user terminal", "User Equipment", "UE", "site", "station", "STA", "user device", "user agent", "User Agent", "UA", "user equipment", "mobile device" and "device" are all alternative terms with synonyms for "terminal" in this document.
[0089] The "network device" mentioned in this application may be a network access device, a device capable of configuring terminal communication resources, including systems and devices that are improvements to peer devices in traditional wireless telecommunications systems. Such advanced or next-generation devices may be included in a long-term evolution LTE communication system, a 5G communication system, a future evolution system, or a variety of communication convergence systems, for example, an Evolved Universal Terrestrial Radio Access Network Node B (E-UTRAN Node B, referred to as eNB) included in an LTE system, a New Radio Access Node B (NRNodeB) included in a 5G communication system, other wireless access points or similar components, any such component will be referred to as a network device in this article, but it should be understood that this is not a limitation on such devices.
[0090] In this application, the term "terminal group" refers to a terminal group composed of multiple terminal devices; "master terminal" and "member terminal" are expressions of objects with different permissions when performing resource configuration and management of the terminal group. It is a representation of a relative identity relationship and does not specifically refer to a specific terminal. All terminals in the terminal group can become master terminals when predetermined conditions are met, and the terminals in the group except the master terminal are member terminals.
[0091] The technical solution of the present application can be applied to solve the resource allocation problem of a group composed of high-speed devices, but it is not limited to high-speed devices, and can also meet the resource allocation needs of a group composed of non-high-speed devices. "High-speed equipment" refers to equipment that moves faster than a predetermined speed in a certain scenario, and is a type of equipment that has very high requirements for communication latency, such as vehicles. It should be further explained that "high-speed equipment" not only includes terminal equipment that is fixedly installed on a subject with high-speed movement capabilities, but also includes terminal equipment that is only in a high-speed movement state in a certain scenario.
[0092] According to the present application, resource configuration is performed for a terminal group, and resource configuration and management of the terminal group are completed through communication with members in the group. Figure 1 A schematic diagram of a V2X communication system in a scenario to which the technical solution provided by the present application is applicable is given. In order to make the technical solution of the present application easier to understand, a fleet application scenario is used as an example for description, and this scenario should not be understood as a limitation on the technical solution of the present application. The communication system may include one or more network devices 100 (only one is shown) and at least two terminals connected to the network device 100 that can form a group, specifically a vehicle terminal 200 in this scenario. In the V2X communication system, the group may be one or more. The network device 100 may be a device that can communicate with the vehicle terminal 200 and can configure communication resources for the vehicle terminal 200. In the fleet scenario, at least two vehicle terminals 200 that meet certain conditions are divided into a fleet, and this fleet is considered to be a terminal group. The formation of a fleet can be divided by the network device 100 according to predetermined conditions (such as the distance between the vehicle terminals 200, the moving speed of the vehicle terminals 200, etc.), or it can be formed by mutual negotiation among the vehicle terminals 200. The negotiated formation method is a more proactive formation method, and can meet the situation where there is no network coverage, or there is network coverage but in order to reduce the pressure on the network side, it can achieve more efficient and stable communication needs without the intervention of the network device 100.
[0093] After the formation of the fleet, the vehicle terminals 200 in the fleet will be divided into group identities with corresponding permissions, which are divided into the fleet leader as the main terminal and the fleet members as member terminals. The fleet leader is responsible for the management and maintenance of the fleet, including the management of fleet communication resources and the configuration of communication resources for fleet members. The fleet leader can be designated by the network device 100 according to predetermined conditions (such as device capabilities, device locations, etc.), or it can be generated in the fleet by competition or election. Those skilled in the art can choose the implementation method according to the means of the prior art, which is not the focus of this application and will not be expanded here. In the V2X communication system, members in the fleet can communicate with each other, members of different fleets can also communicate, and fleet A and fleet B can also communicate with each other through the fleet leader. The V2X communication involved in the vehicle terminal 200 mainly involves driving information and traffic status information, such as speed, direction, next action (such as braking, acceleration, etc.). In order to realize the communication of the fleet, the resource configuration solution of this application is proposed.
[0094] In V2X technology, the Physical Sidelink Control Channel (PSCCH) is used to transmit control information. The control information indicates the communication resources, receiving parameters and other information that the data information receiving end needs to configure, for example, at least one of frequency domain resources, time domain resources, modulation and coding scheme (MCS), antenna configuration, etc.
[0095] The Physical Sidelink Shared Channel (PSSCH) is used to transmit data information. In the fleet application scenario, the corresponding data information includes driving information and traffic condition information, such as speed, direction, next action (such as braking, acceleration, etc.), etc.
[0096] Embodiment 1
[0097] According to an embodiment of the present application, the resource configuration process includes steps executed by a master terminal in a terminal group and steps executed by a member terminal in the terminal group. In order to facilitate understanding of the correspondence between different resource configuration methods and member terminal execution methods in the embodiments, the steps executed by the master terminal and the steps executed by the member terminal are described together in this embodiment and subsequent embodiments. However, it is by no means limited to the steps on the master terminal side and the steps on the member terminal side must be executed together. The technical solution proposed in the present application has improvements on both the master terminal side and the member terminal side.
[0098] Take the whole system as an example to describe. Figure 2 This is a flow chart of the first embodiment of a resource configuration method provided by the present application. The method comprises:
[0099] S101. After obtaining the identity of the terminal group manager, the master terminal determines the communication resources for sending resource indication information.
[0100] Among them, the configuration of the communication resources used for the main terminal to transmit the resource indication information can be scheduled and configured by the network device. The main terminal makes a resource request to the network device via an uplink and reports its own resource buffer status report (SideLink Buffer Status Report, referred to as SL-BSR) for side link (SideLink, referred to as SL) transmission. The network device schedules the main terminal to perform SL transmission at a specific time-frequency resource position according to the received SL-BSR. Specifically, the network device instructs the main terminal to send the main control information at a specific time-frequency position through downlink control information (Downlink Control Information, referred to as DCI). The member terminal can know the corresponding resource location for receiving the main control information based on the DCI. For the resources that can be scheduled and configured by the network equipment, they can be relatively flexible resources or relatively fixed resources, such as dedicated frequency domain resources. In this case, for the member terminal, the frequency domain position where the main control information is transmitted is at a relatively fixed number of frequency domain positions, so it can be directly detected at these positions without determining the frequency domain position corresponding to the main control information, and can be selected to send or receive in time (for example, in units of one subframe). The dedicated frequency domain resources can be broadcast or multicasted by the network equipment through system messages or radio resource control (Radio Resource Control, referred to as RRC) signaling, or directly defined in the standard. The way the master terminal determines the communication resources is not limited to the above two. There can also be a way, that is, terminal self-selection, that is, the resource allocation of the master terminal is selected by the master terminal itself, and the master terminal can judge whether a certain resource is occupied and whether a certain time-frequency resource can be selected as a transmission resource based on the listening history control information / historical data information and the size of the received energy.
[0101] When there are multiple terminal groups, the resources for the master terminal of each terminal group to transmit resource indication information are also configured in the above manner. The above resources can be extended to the concept of a resource pool, that is, the resources in the resource pool can be designated and allocated by the network equipment for the master terminals of multiple terminal groups, or they can be obtained through self-selection and competition among these master terminals.
[0102] Specifically, the indication information of the communication resource for sending the resource indication information should include the starting resource block (RB) position of the communication resource and the number of consecutive RBs.
[0103] The manner in which the master terminal determines the communication resource for sending the resource indication information is not limited here, and those skilled in the art can implement it by various means that they can think of. This is not a necessary step involved in the improvement of the technical solution of this application.
[0104] The communication resources determined by the master terminal to be available for configuration to the terminal group are resources in the edge link dedicated resource pool, and may also be obtained through network device scheduling or autonomous selection by the master terminal. This application does not limit the method by which the master terminal determines the communication resources available to the terminal group.
[0105] S102: The master terminal sends public resource indication information to each member terminal.
[0106] S103: The master terminal sends dedicated resource indication information to each member terminal.
[0107] It should be noted that there is no necessary execution order for step S102 and step S103. Optionally, the dedicated resource indication information and the public resource indication information are sent by the master terminal in batches or simultaneously.
[0108] The master terminal can determine the frequency domain position of each resource indication information transmission according to the indicated starting RB position and the number of consecutive RBs. RB is the minimum frequency domain unit of resource allocation for physical layer data transmission, which is a number of consecutive subcarriers in the frequency domain, such as 12 subcarriers.
[0109] In the present application, a communication cycle of a terminal group is defined, which is specifically a fleet cycle (PlatoonInterval) for the fleet scenario, that is, each resource indication information is sent once every PlatoonInterval. Optionally, in the same cycle, if the dedicated resource indication information and the public resource indication information are sent by the master terminal in batches, then the communication resources corresponding to these two information are located continuously in the time domain resources. The size of the communication cycle can be fixed by a standard, or configured by a network device, and can be specifically notified through high-level signaling, such as RRC signaling or system messages. The starting time of the communication cycle can be the starting time of the subframe where the master terminal sends the resource indication information, or the starting time of the first subframe after the resource indication is sent.
[0110] Specifically, still taking the fleet scenario as an example, after the fleet is formed, the team leader will send resource indication information in the fleet period PlatoonInterval to configure and manage the fleet communication resources. For the fleet, considering it more comprehensively, the communication involved includes the communication between all members within the fleet, which is used to share the driving information of each member of the team, the traffic conditions and other information, and also includes the communication of the fleet as a whole to external objects (such as vehicles outside the fleet) to transmit fleet information. Therefore, in the configuration of communication resources, two types of resources will be configured: internal communication resources and external communication resources. Dedicated communication resources are internal time-frequency resources dedicated to each member terminal for communication within the terminal group, and public communication resources are external time-frequency resources shared by all member terminals for communication with objects outside the terminal group.
[0111] Specifically, the master terminal may send the resource indication information to each member terminal by broadcasting or multicasting within the terminal group.
[0112] Optionally, in terms of indication, the time-frequency resources for external communication and the time-frequency resources for internal communication of each member do not overlap in the time domain and the frequency domain.
[0113] S104: The member terminal receives the public resource indication information, and determines a public communication resource according to the public resource indication information.
[0114] The terminal group is taken as a whole. After all the terminals in it join the terminal group, they still maintain the same status as before joining the terminal group, and broadcast some of their own information to the surrounding terminals at certain communication resource locations. As a member of the terminal group, it is necessary for the terminal to send the information of the terminal group to the outside to ensure the safety and effectiveness of the operation of the terminal group as a whole. Therefore, the member terminal can determine the public communication resources according to the public resource indication information sent by the master terminal. After receiving the public communication resource indication information, the member terminal sends the terminal group public control information to the receiving object outside the terminal group at the indicated time-frequency resource location to instruct the receiving object to receive the terminal group public data information according to the public control information. The public control information includes the time-frequency resource location indication information, which may include information indicating the starting position of the frequency domain RB and the number of consecutive RBs, and which subframes in the time domain.
[0115] Optionally, taking the convoy scenario as an example, the convoy as a whole can inform other objects outside the convoy of relevant information about the convoy. Whether the relevant information of the convoy can effectively reach the receiving end has a great impact on driving safety, because the convoy contains several vehicles, and the distance between the head and tail of the convoy is far in terms of physical distance. If any party sends convoy data information (for example, convoy speed, convoy target, convoy is about to turn, etc.) to inform users outside the convoy to avoid or drive carefully, it may cause the remote user to be unable to receive or the probability of receiving the correct information to decrease, such as Figure 1 For example, in Figure 1 In the example, if the fleet data information of fleet B is sent by the fleet leader B, it may cause the vehicle user D to fail to receive it correctly. Therefore, it can be considered that the fleet data information is sent by all members of the fleet at the same time and frequency resources at the same time, and the fleet data information sent by each fleet member is the same. In this way, mutual interference can be avoided. Different users send the same content in the same time and frequency resources, which is equivalent to bringing the gain of transmission power, increasing the transmission range and the probability of correct reception at the receiving end. Then, for the configuration of resources for external communication of fleet members, all members can be instructed to use the same time domain resources and the same frequency domain resources to jointly send public control information to the outside through public communication resource indication information. After receiving the public communication resource indication information, all fleet members simultaneously send the fleet public control information to the receiving object outside the fleet at the indicated time and frequency resource position to instruct the receiving object to receive the fleet public data information according to the public control information. In this way, the public control information includes time and frequency resource position indication information, specifically indicating the starting position of the frequency domain RB and the number of consecutive RBs, and which subframe in the time domain.
[0116] S105. The member terminal receives the dedicated resource indication information, and determines a dedicated communication resource according to the dedicated resource indication information.
[0117] It should be noted that there is no necessary order for executing step S104 and step S105, and they can be executed separately or simultaneously.
[0118] Specifically, the communication resources for internal communication are dedicated time-frequency resources determined by each member terminal according to the dedicated resource indication information. Each member terminal sends its own dedicated control information to other member terminals in the group at the determined dedicated time-frequency resource position to instruct other member terminals to receive dedicated data information according to the dedicated control information. In the convoy scenario, the data information of the member terminal includes driving information, such as vehicle speed, next action, direction, etc., and may also include traffic condition information such as congestion or accidents known to the member terminal.
[0119] The member terminal determines the frequency domain resources used for internal communication, which can be determined by dedicated resource indication information, and the indication information includes the starting RB position and the number of consecutive RBs indicating the resources used by the member terminal. Optionally, the member terminals in a group are configured to use the same frequency domain resources to send and receive dedicated control information, and the frequency domain resources used by the master terminal to send resource indication information and the member terminal to send control information can be different. It can be understood that, unlike the master terminal indicating that all member terminals send and receive dedicated control information on the same frequency domain resources, the master terminal can indicate a set of dedicated frequency domain resources, and the member terminals in a group can be configured to use different frequency domain resources in the set to send and receive member control information. Compared with the method of using the same frequency domain resources, this method increases certain complexity because the receiving end needs to perform blind detection at multiple frequency domain positions. The configuration of different frequency domain resources between member terminals can be achieved by the master terminal specifying or the member terminal self-selecting. The self-selection can be specifically determined by listening to historical control information / historical data information and the size of the received energy to determine whether the corresponding resources have been occupied or whether future resources have been reserved to avoid these reserved resources. As long as the solution can realize frequency domain resource configuration, it can be used here without specific restrictions.
[0120] For the configuration of the time domain resources used by the member terminals, optionally, it can be configured through a bitmap. The bitmap, such as "100...101", can contain M bits. In a terminal group communication cycle (in the fleet scenario, it is: the fleet cycle PlatoonInterval), each bit corresponds to a subframe, and each bit corresponds to a subframe separated by Xms (X is a positive number, such as 20). The bitmap can be reused in a terminal group communication cycle, that is, the bitmap is looped until the terminal group communication cycle ends. For example, the bit "1" in the bitmap indicates that the corresponding subframe (called: the fleet subframe (Platoon Subframe) in the fleet scenario) that can be used by the member terminal is used for V2X communication between member terminals in the group. The bit "0" in the bitmap indicates that the corresponding subframe that can be used by the member terminal cannot be used for V2X communication between member terminals in the group. For the configuration of the time domain resources used by the members, it can also be configured by indicating the subframe index. As long as the solution that can realize the time domain resource configuration can be used here, there is no specific limitation.
[0121] For the above steps S104 and S105, further, the member terminal receives the resource indication information sent by the main terminal through the side link communication, that is, the PC-5 air interface defined by 3GPP (or the air interface for SL communication defined by the subsequent evolution standard) is used for direct communication, which can be forwarded without network equipment, and the realization is essentially a D2D communication, and specifically in the field of Internet of Vehicles, it is a V2V communication. Optionally, the public resource indication information, dedicated resource indication information, public control information and dedicated control information can all be transmitted through the physical side link control channel PSCCH
[0122] Through a resource configuration method of an embodiment of the present application, the configuration mode of the public communication resources and private communication resources of the member terminals indicated by the resource indication information is realized, so that the public communication resources and private communication resources of the member terminals in the terminal group are configured, the effective management and maintenance of the terminal group resources are realized, and the security of high-speed device movement is enhanced.
[0123] Embodiment 2
[0124] Figure 3 This is a flow chart of a second embodiment of a resource configuration method provided by the present application. The difference from the first embodiment is that in this embodiment, the public resource indication information and the dedicated resource indication information are carried in the main control information and sent simultaneously, and the method includes:
[0125] S201. After obtaining the identity of the terminal group manager, the master terminal determines the communication resources for transmitting the master control information.
[0126] Among them, the main control information is used for the transmission of subsequent data information of the main terminal, which may include basic receiving parameters required for receiving data information. Similar to the communication resource configuration for sending resource indication information in Example 1, the configuration of the communication resources used for the main terminal to transmit the main control information can be dynamically configured by the network device in one way, and there can also be another way, which is the terminal self-selection mode, that is, the resource allocation of the main terminal is selected by the main terminal itself. For specific instructions, please refer to Example 1, which will not be repeated here.
[0127] In the case of multiple terminal groups, the resources for the main terminal of each terminal group to transmit the main control information are also configured in the above manner. The above resources can be extended to the concept of a resource pool, that is, the resources in the resource pool can be assigned by the network device to multiple team leaders, or they can be obtained by self-selection among team leaders through competition. Specifically, the indication information indicating the communication resource for sending the main control information should include the starting resource block (Resource Block, referred to as RB) position of the communication resource and the number of consecutive RBs. The way in which the main terminal determines the communication resource for transmitting the main control information is not limited here, and those skilled in the art can achieve it by various means that they can think of. This is not a necessary step involved in the improvement of the technical solution of this application. The communication resources determined by the main terminal that can be used to configure the terminal group are resources in the dedicated resource pool of the side link, and can also be obtained by means such as network device scheduling or autonomous selection by the main terminal. This application does not limit the way in which the main terminal determines the communication resources that can be used for the terminal group.
[0128] S202: The master terminal sends master control information carrying instructions for dedicated communication resources and public communication resources to each member terminal.
[0129] The master terminal can determine the frequency domain location of the main control information transmission according to the indicated starting RB location and the number of consecutive RBs. RB is the minimum frequency domain unit of resource allocation for physical layer data transmission, which occupies one time slot in the time domain and is 12 consecutive subcarriers in the frequency domain.
[0130] In this application, a period for sending main control information, that is, a communication period of a terminal group, is defined. For the convoy scenario, it is specifically a convoy period (PlatoonInterval), that is, the period for the convoy leader to send the main control information, which is sent every PlatoonInterval. The size of the communication cycle can be fixed by a standard, or configured by a network device, which can be notified through high-level signaling, such as RRC signaling or system messages. The starting time of the communication cycle can be the starting time of the subframe where the main control information is sent by the master terminal, or the starting time of the first subframe after the main control information is sent.
[0131] The master terminal can indicate the basic receiving parameters required for the member terminal to receive the master terminal data information through the master control information. In this embodiment, the master control information also carries resource indication information to indicate the configuration of the member terminal communication resources. The resources for the master terminal to send data information are indicated in the downlink scheduling information, which will not be described in detail here.
[0132] Specifically, still taking the fleet scenario as an example, after the fleet is formed, the team leader will send the main control information in the fleet period PlatoonInterval to configure and manage the fleet communication resources. For the fleet, considering it more comprehensively, the communication involved includes the communication between all members within the fleet, which is used to share the driving information of each member in the team, the traffic conditions and other information, and also includes the communication of the fleet as a whole to external objects (such as vehicles outside the fleet) to transmit fleet information. Therefore, in the configuration of communication resources, two types of resources will be configured: internal communication resources and external communication resources. Dedicated communication resources are internal time-frequency resources dedicated to each member terminal for communication within the terminal group, and public communication resources are external time-frequency resources shared by all member terminals for communication with objects outside the terminal group.
[0133] Specifically, the master terminal may send the master control information to each member terminal by broadcasting or multicasting within the terminal group.
[0134] Optionally, in terms of indication, the time-frequency resources for external communication and the time-frequency resources for internal communication of each member do not overlap in the time domain and the frequency domain.
[0135] S203: The member terminal receives the main control information, and according to the main control information, the member terminal determines the dedicated communication resources for internal communication and the public communication resources for external communication.
[0136] The member terminal receives the main control information sent by the main terminal through the side link communication, that is, the PC-5 air interface defined by 3GPP is used for direct communication, which can be forwarded without going through the network equipment. The essence of the realization is a D2D communication. Specifically in the field of Internet of Vehicles, it is a V2V communication. The frequency domain resource indication and time domain resource indication method in the dedicated communication resources and public communication resources are similar to those in Example 1. For the explanation of public communication resources and dedicated communication resources, please refer to the description related to step S104 and step S105 in Example 1, which will not be repeated here. Optionally, the public resource indication information can also indicate all member terminals to simultaneously send the public control information of the terminal group to the receiving objects outside the terminal group at the indicated time-frequency resource position. This increases the range of public information transmission, improves the probability of public information being correctly received, and enhances the security of high-speed device movement.
[0137] Further optionally, the main control information, common control information and dedicated control information may all be transmitted via a physical side link control channel PSCCH.
[0138] Optionally, the public communication resources and the dedicated communication resources do not overlap in the time domain. It is understandable that the public communication resources and the dedicated communication resources used by the member terminals may be the same or different in the frequency domain, which is not limited here.
[0139] Through a resource configuration method of an embodiment of the present application, the configuration method of the public communication resources and private communication resources of the member terminals indicated by the main control information is implemented to realize the configuration of the public communication resources and private communication resources of the member terminals in the terminal group, realize the effective management and maintenance of the terminal group resources, and enhance the security of high-speed equipment movement.
[0140] Figure 4 The technical solution provided in this application is a schematic diagram of time-frequency resources for fleet resource allocation in a fleet scenario. Figure 4 In the bitmap, the ordinate indicates the frequency domain resource distribution, and the abscissa indicates the time domain resource distribution. In the time domain, the position of the bit "1" is the platoon subframe that can be used by the member terminal for V2X communication between the member terminals in the group. The bit "0" in the bitmap indicates that the corresponding subframe that can be used by the member terminal cannot be used for V2X communication between the member terminals in the group. Figure 4 It can be seen that the starting RB position (RBstart) and the number of consecutive RBs (M consecutive RBs) configured resources for sending physical layer control information (which can be the public resource indication information / dedicated resource indication information in Example 1, or the main control information in Example 2) determined by the team leader are the PSCCH channel resources corresponding to the team leader. The team leader sends physical layer control information to the team members through the PSCCH channel, which can indicate the PSSCH channel resources for the team members to receive the leader data information (Leader Data), the PSCCH channel resources for the team members to send their own dedicated control information internally, and the PSCCH channel resources for the team members to send public control information to the outside together. Team members send and receive dedicated control information at the same frequency domain resource position, and the dedicated control information is used to instruct the receiving end to receive member dedicated data (Data) according to the control information. Team members send public control information to the outside at the same frequency domain and time domain resource position (the same frequency domain and time domain resources are used as an example in this design, but it should be understood that this application is not limited to this), and the public control information is used to instruct the receiving end to receive team data (Platoon Data) according to the control information. The indication information in these control information includes information indicating the frequency domain resources of the data information corresponding to the PSCCH control information of the receiving end. Optionally, the PSSCH channel frequency domain resources for transmitting data information and the PSCCH channel resources for transmitting control information are continuous in the frequency domain, and of course they can also be discontinuous. When they are discontinuous, the PSCCH control information will carry the corresponding indication information. The indication information of these control information also includes the basic receiving parameters required by the receiving end to receive the corresponding data information, such as the modulation and coding scheme (MCS), antenna configuration and other parameters.
[0141] Figure 5The technical solution provided in this application is another schematic diagram of time-frequency resources for fleet resource allocation in a fleet scenario. Figure 4 Different from the case where the team leader instructs all members to send and receive dedicated control information on the same frequency domain resources, the team leader can instruct a set of scheduling allocation resource pools, that is, a set of dedicated frequency domain resources, such as Figure 5 As shown, it indicates a set containing 2 PSCCH frequency domain resources. The member terminals in a group can be configured to use different frequency domain resources in the set to send and receive member control information. It can indicate the starting RB position and the number of consecutive RBs of the PSCCH frequency domain resources used by the set. Members can determine how many available PSCCH frequency domain resources are included based on the number of RBs. The resources in the set can be configured by the leader's designation or by the members' self-selection. Its indication method is similar to Figure 4 Instructions in the Figure 4 It is understandable that, in the set of dedicated frequency domain resources, some dedicated frequency domain resources available to member terminals may be the same as or different from the public frequency domain resources, and no specific limitation is made in the technical solution of this application.
[0142] Figure 6 A schematic diagram of time-frequency resources for allocating fleet resources in a multi-vehicle scenario for the technical solution provided in this application. In this design, the team leader of Platoon A (Platoon A) and the team leader of Platoon B (Platoon B) determine their respective PSCCH resources and PSSCH resources. The way in which the team leader determines the above resources has been described in the previous text and will not be repeated here. Team members receive and decode the PSCCH control information of their respective team leaders based on the team identification, and learn the resource locations for receiving PSCCH control information sent by other members of their own team and sending PSCCH control information themselves, as well as the resource locations for all members of their respective teams to jointly send team public control information. The identification of the above-mentioned fleet can be a dynamically allocated Radio Network Temporary Identity (RNTI) for identifying different fleets, or a public fleet RNTI (Platoon-RNTI) can be used to first decode the PSCCH, and then identify the RNTI of different fleets according to the fleet ID (Platoon ID) in the PSCCH. In either case, the Platoon-RNTI or Platoon ID is already known to the members of the fleet when they join the fleet / form a fleet.
[0143] Figure 7Another schematic diagram of time-frequency resources for fleet resource allocation in a fleet scenario for the technical solution provided by this application. In this design, considering that the size of PSCCH on the physical layer is limited, in order to further reduce the overhead of resources occupied by PSCCH on the physical layer, the resource location indication information of the public control information (i.e., public resource indication information) can be placed in PSSCH, specifically in the Media Access Control (MAC) header, and carried in the MAC control information (MAC Control Element, MAC CE). Figure 7 An example of this implementation is given in . The configuration of other time-frequency resources in this design is similar to Figure 4 The design is similar to that of , which will not be described here. It can be understood that Figure 7 In the example, only the public resource indication is carried in the MAC control information and transmitted through the PSSCH channel, but this does not constitute a limitation to the present application. In other possible designs, part of the public resource indication information and the dedicated resource indication information are sent to each of the member terminals through the PSCCH channel, and the remaining part of the public resource indication information and the dedicated resource indication information are carried in the MAC control information and sent to each of the member terminals through the PSSCH channel. Among them, the public resource indication information and the part of the dedicated resource indication information may refer to one of the two as a part, that is, the public resource indication information or the dedicated resource indication information is sent through the PSCCH channel; it may also refer to a part of the public resource indication information and / or a part of the dedicated resource indication information; it may also be a part of the public resource indication information and the dedicated resource indication information, or a part of the public resource indication information and / or the dedicated resource indication information.
[0144] Embodiment 3
[0145] Figure 8 This is a flowchart of a third embodiment of a resource configuration method provided by the present application. The difference between this embodiment and the first or second embodiment is that the master terminal also sends reservation indication information to the member terminal. The same content described in the first or second embodiment is not repeated here. The method includes:
[0146] S301: The master terminal determines the communication resources for sending resource indication information and reservation indication information.
[0147] The communication resource determination for the resource indication information and the reservation indication information may be similar to the communication resource determination method in step S101 or S201, and will not be described in detail herein.
[0148] S302: The master terminal sends dedicated resource indication information, public resource indication information and reservation indication information to each member terminal.
[0149] Step S302 does not limit the simultaneous transmission of dedicated resource indication information, public resource indication information, and reservation indication information; optionally, referring to the description of Embodiment 1 and Embodiment 2, dedicated resource indication information and public resource indication information may be transmitted separately or simultaneously, or may be carried in the main control information and transmitted simultaneously. Similarly, reservation indication information may be transmitted together with corresponding resource indication information or may be transmitted separately. Such information may be transmitted by broadcasting or multicasting in the terminal group.
[0150] Among them, dedicated communication resources are resources for each member terminal to communicate within the terminal group, which can be indicated by dedicated resource indication information, and public communication resources are resources shared by all members for communicating with objects outside the terminal group, which can be indicated by public resource indication information. The reservation indication information may include a bit. For example, if it is "1", it means that in the next terminal group communication cycle (PlatoonInterval in the fleet scenario), the member terminal uses the same dedicated (internal) / public (external) frequency domain resources and dedicated (internal) / public (external) time domain resources (if indicated by a bit map, it can be the same bit map) for V2X communication, so that the member terminal does not need to configure the resources again, reducing system overhead. If it is "0", it means that in the next terminal group communication cycle (PlatoonInterval in the fleet scenario), the member terminal needs to re-determine the configured communication resources according to the resource indication information. The content indicated by "1" / "0" is only an exemplary description and is not a limitation to this solution. Regardless of whether the indication is "1" or "0", the master terminal must send resource indication information and / or master control information in each terminal group communication cycle so that the member terminal newly added to the terminal group can be configured with communication resources and receive data information from the master terminal. Optionally, the public resource indication information, dedicated resource indication information, master control information, public control information and dedicated control information can all be transmitted via the physical side link control channel PSCCH.
[0151] Optionally, the reservation indication information may be used to pre-indicate the unified configuration of dedicated time-frequency resources and public time-frequency resources, or may be used to pre-indicate the configuration of internal and external communication resources respectively.
[0152] S303: The member terminal receives the above indication information sent by the master terminal. According to the indication information, the member terminal determines the dedicated communication resources and the public communication resources within the predetermined communication period of the terminal group, and determines whether to continue to use the corresponding communication resources after the predetermined communication period of the terminal group.
[0153] The communication method between the member terminal and the master terminal can refer to the description of the first embodiment. The design details of the member terminal determining the dedicated communication resources and the public communication resources can refer to the description of the first embodiment or the second embodiment above. When the member terminal indicates that it can continue to be used, when the communication cycle after the scheduled communication cycle arrives, it is not necessary to parse the corresponding resource indication information according to the reservation indication information, and thus no longer need to perform the reconfiguration process such as competition for the corresponding resources. When the indication is that it cannot continue to be used, when the communication cycle after the scheduled communication cycle arrives, the resource indication information is received and parsed, and the resource reconfiguration process is performed. The resource reconfiguration method is similar to the resource configuration method described above, and can refer to the description of the first embodiment or the second embodiment, which will not be repeated here. The scheduled communication cycle can be one communication cycle or multiple communication cycles.
[0154] Through a resource configuration method of an embodiment of the present application, not only the effective configuration and management of terminal group resources within a predetermined communication cycle is achieved, but also pre-indication is provided for the configuration of terminal group resources in subsequent cycles, thereby avoiding repeated configuration and reducing system overhead.
[0155] Fig. 9 The technical solution provided in this application is a schematic diagram of the time-frequency resource allocation of the fleet resources when there is a reservation indication information in the fleet scenario. In this design, the scheduled communication cycle of the terminal group is set to one as an example. The reservation indication information indicates that in the next PlatoonInterval, the fleet members use the same dedicated time-frequency resources and public time-frequency resources as the current cycle for V2X communication. The configuration of specific time-frequency resources in this design is different from Figure 4 The design is similar and will not be described here.

The difference between this embodiment and embodiment 1 or embodiment 2 is that this embodiment does not involve the configuration instruction of dedicated communication resources, and this embodiment focuses on the configuration implementation of public communication resources. In this embodiment, the configuration of dedicated communication resources can be issued by the network device to each member terminal, or the master terminal can be configured by other means, which is not concerned here. The method includes:
[0158] S401: The master terminal determines the communication resources for sending public resource indication information.

[0161] Optionally, the public resource indication information may be carried in the main control information and sent. For the description of the main control information, see Embodiment 2.
[0162] Specifically, still taking the convoy scenario as an example, after the convoy is formed, the team leader will send public resource indication information in the convoy period PlatoonInterval to configure and manage the convoy communication resources, in order to realize the communication of the convoy as a whole to external objects (such as vehicles outside the convoy) to transmit convoy information. The indication of public communication resources has been described in detail in the first embodiment and will not be repeated here.
[0163] S403: The member terminal receives the public resource indication information, and according to the public resource indication information, the member terminal determines the public communication resources for external communication.
[0164] The communication method between the member terminal and the master terminal can refer to the description of the first embodiment.
[0165] The determination of the public communication resources for external communication is similar to that in the first embodiment, and has been described in detail in the first embodiment, so it will not be repeated here.
[0166] Through a resource configuration method of an embodiment of the present application, the configuration method of the terminal group's public communication resources indicated by the public resource indication information is used to realize the configuration of the public communication resources of the member terminals in the terminal group, complete the effective configuration and management of the terminal group's external communication resources, and enhance the security of high-speed device movement.

[0170] The communication resource determination method may be similar to the communication resource determination method in step S101 or S201, and will not be described in detail here.
[0171] S502: The master terminal sends public resource indication information and reservation indication information to each member terminal.
[0172] Step S502 does not limit the simultaneous transmission of the public resource indication information and the reservation indication information; optionally, referring to the description of the third embodiment, the reservation indication information can be transmitted together with the corresponding resource indication information or can be transmitted separately, or can be carried in the main control information and transmitted. According to the reservation indication information, the member terminal can be instructed whether to continue to use the public communication resources configured this time after the predetermined communication period of the terminal group.
[0173] S503: The member terminal receives the above indication information, and according to the above indication information, the member terminal determines the common communication resource for external communication, and determines whether to continue to use the communication resource after the predetermined communication period of the terminal group.
[0174] If the public communication resources for external communication configured this time can continue to be used, the member terminal continues to send public control information externally at the same time-frequency position after a predetermined communication period, thereby avoiding the overhead caused by reconfiguration.
[0175] Through a resource configuration method in an embodiment of the present application, not only is effective configuration and management of external communication resources of a terminal group achieved within a predetermined communication cycle, but also pre-indication is provided for the configuration of external resources of the terminal group in subsequent communication cycles, thereby avoiding repeated configuration and reducing system overhead.
[0176] Embodiment 6
[0177] Fig.12 This is a flowchart of the first embodiment of another resource configuration method provided by the present application. The difference between this embodiment and embodiment 1 or embodiment 2 is that this embodiment does not involve the configuration instruction of public communication resources, and this embodiment focuses on the configuration implementation of dedicated communication resources. In this embodiment, the configuration of public communication resources can be specified by the network device, or the master terminal can be configured by other means, which is not concerned here. The method includes:
[0178] S601: The master terminal determines the communication resources for sending dedicated resource indication information.
[0179] The communication resource determination for the dedicated resource indication information may be similar to the communication resource determination method in step S101 or S201, and will not be described in detail herein.
[0180] S602: The master terminal sends dedicated resource indication information to each member terminal.
[0181] Optionally, the dedicated resource indication information may be carried in the main control information and sent. For the description of the main control information, see Embodiment 2.
[0182] Specifically, still taking the convoy scenario as an example, after the convoy is formed, the team leader will send the main control information in the convoy period PlatoonInterval to configure and manage the convoy communication resources. In order to achieve the maintenance of the convoy, the convoy needs to share information and members need to be able to communicate within the team. Therefore, after the convoy is formed, the team leader will configure the dedicated communication resources for members to communicate within the convoy. The indication of dedicated communication resources has been described in detail in the first embodiment and will not be repeated here.
[0183] S603: The member terminal receives the dedicated resource indication information, and according to the dedicated resource indication information, the member terminal determines the dedicated communication resources for internal communication.

[0186] Embodiment 7
[0187] Fig.13 This is a flowchart of a second embodiment of another resource configuration method provided by the present application. The difference between this embodiment and the sixth embodiment is that there is also reservation indication information. The same content described in the sixth embodiment is not repeated here. The method includes:
[0188] S701: The master terminal determines the communication resources for sending dedicated resource indication information and reservation indication information.
[0189] The communication resource determination for the dedicated resource indication information may be similar to the communication resource determination method in step S101 or S201, and will not be described in detail herein.
[0190] S702: The master terminal sends dedicated resource indication information and reservation indication information to each member terminal.
[0191] Step S702 does not limit the dedicated resource indication information and the reservation indication information to be sent at the same time; optionally, referring to the description of the third embodiment, the reservation indication information can be sent together with the corresponding resource indication information or separately, or can be carried in the main control information for sending. According to the reservation indication information, the member terminal can be instructed whether to continue to use the internal communication resources configured this time after the predetermined communication period of the terminal group.
[0192] S703: The member terminal receives the above indication information, and according to the above indication information, the member terminal determines the dedicated communication resource for internal communication, and determines whether to continue to use the communication resource after the predetermined communication period of the terminal group.
[0193] If the dedicated communication resources for internal communication configured this time can continue to be used, the member terminal continues to send dedicated control information internally at the same time-frequency position within the predetermined communication cycle, thereby avoiding the overhead caused by reconfiguration.
[0194] Through a resource configuration method of an embodiment of the present application, the configuration of dedicated communication resources for member terminals in a terminal group and the pre-indication of dedicated communication resource configuration after a predetermined communication cycle are realized through the indication of dedicated resource indication information and reservation indication information. That is, not only the effective configuration and management of the internal communication resources of the terminal group in the predetermined communication cycle are realized, but also the configuration of the internal communication resources of the terminal group in subsequent cycles is pre-indicated, thereby avoiding repeated configuration and reducing system overhead.
[0195] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the process of resource configuration for communication between the main terminal and the member terminal. It is understandable that the terminals of various roles, such as the main terminal or the member terminal, include hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. It should be easily appreciated by those skilled in the art that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.
[0196] The embodiment of the present application can divide the functional modules of the main terminal or the member terminal according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical functional division. There may be other division methods in actual implementation. The following is an example of dividing each functional module according to each function.
[0197] The present application also provides a terminal. If the terminal is used as a master terminal in a terminal group, it can be used to execute Figure 2-Figure 3 , Figure 8 , Figure 10-13The steps performed by the master terminal in any of the figures can be used to perform the steps if the terminal is a member terminal in the terminal group. Figure 2-Figure 3 , Figure 8 , Figure 10-13 The steps performed by the member terminal in any of the figures. Fig.14 A simplified terminal structure diagram is shown. For ease of understanding and illustration, Fig.14 In the figure, the terminal 1400 takes a mobile terminal as an example, and includes a processor 1401, a memory 1402, a radio frequency circuit 1403, an antenna 1404, and an input-output device 1405. The processor 1401 is mainly used to process the communication protocol and communication data, and to control the terminal, execute the software program, and process the data of the software program. The memory 1402 is mainly used to store the software program and data. The radio frequency circuit 1403 is mainly used for converting the baseband signal and the radio frequency signal and processing the radio frequency signal. The antenna 1404 is mainly used to send and receive radio frequency signals in the form of electromagnetic waves. The input-output device 1405, such as a touch screen, a display screen, a keyboard, etc., is mainly used to receive data input by the user and output data to the user. It should be noted that some types of terminals may not have the input-output device 1405. Among them, the memory 1402 and the processor 1401 can be integrated or independently set.
[0198] When data needs to be sent, the processor 1401 performs baseband processing on the data to be sent, and then outputs the baseband signal to the RF circuit 1403. The RF circuit 1403 performs RF processing on the baseband signal and then transmits the RF signal to the outside in the form of electromagnetic waves through the antenna 1404. When data is sent to the terminal, the RF circuit 1403 receives the RF signal through the antenna 1404, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 1401. The processor 1401 converts the baseband signal into data and processes the data. For ease of explanation, Fig.14 Only one memory 1402 and processor 1401 are shown. In an actual terminal product, there may be one or more processors 1401 and one or more memories 1402. The memory 1402 may also be referred to as a storage medium or a storage device. The memory 1402 may be independent of the processor or may be integrated with the processor 1401, which is not limited in the embodiments of the present application.
