[0161] In order to make the purpose, technical solutions, and advantages of the present application clearer, the following will describe the embodiments of the present application in conjunction with the drawings in the embodiments of the present application.

[0162] In the description, claims, and drawings of this application, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device, etc. that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, etc., or optionally further includes other steps or units inherent to these processes, methods, products, or devices, etc.

[0163] As used herein, "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The phrase appearing in various positions in the description does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art can explicitly and implicitly understand that in the various embodiments of this application, if there is no special description and logical conflict, the terms and / or descriptions among the various embodiments are consistent and can be mutually referred to, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0164] It should be understood that in this application, "at least one (item)" means one or more, "a plurality" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships can exist. For example, "A and / or B" can mean: only A exists, only B exists, and both A and B exist at the same time. Among them, A and B can be singular or plural. The character " / " generally means that the associated objects before and after are in an "or" relationship. "At least one (one) of the following" or its similar expression refers to any combination of these items, including any combination of single item (one) or plural items (ones). For example, at least one (one) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0165] It should be noted that in this application, "indicating" may include direct indication, indirect indication, display indication, and implicit indication. When it is described that a certain indication information is used to indicate A, it can be understood that this indication information carries A, directly indicates A, or indirectly indicates A.

[0166] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated, etc. It is also possible to indirectly indicate the information to be indicated by indicating other information, where there is an association relationship between the other information and the information to be indicated. It is also possible to only indicate a part of the information to be indicated, while the other parts of the information to be indicated are known or pre-agreed. For example, it is also possible to use the arrangement order of each piece of information pre-agreed (such as protocol regulations) to implement the indication of specific information, thereby reducing the indication overhead to a certain extent. The information to be indicated can be sent as a whole, or can be divided into multiple sub-information and sent separately, and the sending periods and / or sending opportunities of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending periods and / or sending opportunities of these sub-information can be pre-defined, such as pre-defined according to the protocol, or can be configured by the transmitting device by sending configuration information to the receiving device.

[0167] It should be noted that in this application, "send" can be understood as "output", and "receive" can be understood as "input". "Send information to A", where "to A" only indicates the direction of information transmission, and A is the destination, and it does not limit that "send information to A" must be a direct transmission over the air interface. "Send information to A" includes directly sending information to A, and also includes indirectly sending information to A through a transmitter. Therefore, "send information to A" can also be understood as "output information destined for A". Similarly, "receive information from A" means that the source of the information is A, including directly receiving information from A, and also includes indirectly receiving information from A through a receiver. Therefore, "receive information from A" can also be understood as "input information from A".

[0168] The method provided in this application can be applied to various communication systems. For example, it can be an Internet of Things (IoT) system, a Narrow Band Internet of Things (NB-IoT) system, a Long Term Evolution (LTE) system, or a 5th-generation (5G) communication system, as well as new communication systems (such as 6G) that appear in the future development of communication.

[0169] The technical solution provided by this application can also be applied to machine type communication (MTC), long term evolution - machine (LTE - M), device - to - device (D2D) network, machine - to - machine (M2M) network, internet of things (IoT) network or other networks. Among them, the IoT network can include, for example, the vehicle - to - everything (V2X) network. The communication methods in the vehicle - to - everything network are collectively referred to as vehicle - to - everything (V2X, where X can represent anything). For example, the V2X can include: vehicle - to - vehicle (V2V) communication, vehicle - to - infrastructure (V2I) communication, vehicle - to - pedestrian (V2P) communication, or vehicle - to - network (V2N) communication, etc. Exemplarily, in Figure 1 shown below, the terminal devices can communicate with each other through D2D technology, M2M technology or V2X technology, etc.

[0170] Please refer to Figure 1 , Figure 1 which is a schematic diagram of a communication system provided by an embodiment of this application.

[0171] As Figure 1 shown, the communication system can include at least one access network device and at least one terminal device.

[0172] The introductions of the access network device and the terminal device are as follows:

[0173] Exemplarily, the access network device may be a next generation node B (gNB), a next generation evolved node B (ng-eNB), or an access network device in future 6G communication, etc. The access network device may be any device with wireless transceiver function, including but not limited to the base station (BS) shown above. The base station may also be a base station in a future communication system such as the sixth generation communication system. Optionally, the access network device may be an access node, a wireless relay node, a wireless backhaul node, etc. in a wireless fidelity (WiFi) system. Optionally, the access network device may be a wireless controller in a cloud radio access network (CRAN) scenario. Optionally, the access network device may be a wearable device or a vehicle-mounted device, etc. Optionally, the access network device may also be a small station, a transmission reception point (TRP) (or may also be referred to as a transmission point), etc. It can be understood that the access network device may also be a base station in a future evolved public land mobile network (PLMN), etc.

[0174] In some deployments, a base station (such as a gNB) may be composed of a centralized unit (CU) and a distributed unit (DU). That is, the functions of the base station in the access network are split, with some functions of the base station deployed in a CU and the remaining functions deployed in a DU. And multiple DUs share one CU, which can save costs and is easy for network expansion. In some other deployments of the base station, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc. In some other deployments of the base station, the base station may also be a radio unit (RU), etc. In some other deployments of the base station, the base station may also be an open radio access network (ORAN) architecture, etc. The present application does not limit the specific type of the base station. Exemplarily, when the base station is an ORAN architecture, the base station shown in the embodiments of the present application may be an access network device in ORAN, or a module in the access network device, etc. In the ORAN system, the CU may also be referred to as an open (O)-CU, the DU may also be referred to as an O-DU, the CU-DU may also be referred to as an O-CU-DU, the CU-UP may also be referred to as an O-CU-UP, and the RU may also be referred to as an O-RU.

[0175] For ease of description, in the following text, the access network device will be taken as an example of a base station to introduce the method involved in this application.

[0176] Exemplarily, the terminal device may also be referred to as a user equipment (UE), a terminal, etc. The terminal device is a device with wireless transceiver functions, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface, such as on a ship; it can also be deployed in the air, for example, deployed on an airplane, a balloon or a satellite, etc. The terminal device can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and so on. It can be understood that the terminal device can also be a terminal device in a future 6G network or a terminal device in a future evolved PLMN, etc.

[0177] It can be understood that the terminal device shown in this application can not only include a vehicle in the vehicle network (such as a whole vehicle), but also include in-vehicle devices or in-vehicle terminals in the vehicle network, etc. This application does not limit the specific form of the terminal device when it is applied to the vehicle network.

[0178] For ease of description, in the following text, the terminal device will be taken as an example of a UE to introduce the method involved in this application.

[0179] As Figure 1 shown, the communication system may further include at least one core network device, and the introduction of the core network device is as follows:

[0180] Exemplarily, the core network device includes services such as user access control, mobility management, session management, user security authentication, and charging. It consists of multiple functional units and can be divided into functional entities on the control plane and the data plane. Among them, the access and mobility management function (AMF) is responsible for user access management, security authentication, and mobility management. The location management function (LMF) is responsible for managing and controlling the positioning service requests of target terminals and processing positioning-related information. The user plane function (UPF) is responsible for managing functions such as the transmission of user plane data and traffic statistics.

[0181] In Figure 1 the shown communication system, there is a core network device, two base stations, and eight UEs, such as Figure 1 the core network device, Base Station 1, and Base Station 2 in it, as well as UE1 to UE8. In this communication system, Base Station 1 can send downlink signals such as configuration information or downlink control information (DCI) to UE1 to UE6, and UE1 to UE6 can send uplink signals such as SRS or physical uplink shared channel (PUSCH) to Base Station 1. Base Station 1 can also send downlink signals to UE7 to UE8 through Base Station 2, and UE7 to UE8 can send uplink signals to Base Station 1 through Base Station 2. Base Station 2 can send downlink signals such as configuration information or DCI to UE7 to UE8, and UE7 to UE8 can send uplink signals such as SRS or PUSCH to Base Station 2. It can be understood that for the communication methods between UEs, reference can be made to the above description and will not be elaborated here.

[0182] It should be understood that Figure 1 exemplarily shows a core network device, two base stations, and eight UEs, as well as the communication links between each communication device. Optionally, the communication system may include multiple base stations, and the coverage range of each base station may include other numbers of UEs, such as more or fewer UEs, etc., and this application does not make any limitations in this regard.

[0183] Each of the above communication devices, such as Figure 1The core network device, base station 1, base station 2, UE1 to UE8 can be configured with multiple antennas. The multiple antennas can include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals, etc. The embodiments of the present application do not limit the specific structure of each communication device. Optionally, the communication system may further include other network entities such as a network controller, a mobility management entity, etc., and the embodiments of the present application are not limited thereto.

[0184] It can be understood that Figure 1 The schematic diagram of the communication system shown is only an example. For other forms of schematic diagrams of communication systems, reference can be made to relevant standards or protocols, etc., which will not be elaborated here one by one.

[0185] Each of the embodiments shown below can be applicable to Figure 1 the communication system shown, and can also be applicable to other forms of communication systems. In this regard, it will not be elaborated below.

[0186] The present application provides a communication method, which is applied to the field of communication technologies, such as communication in scenarios where multiple A-IoT devices are densely deployed. To more clearly describe the solution of the present application, some knowledge related to the communication of A-IoT devices will be introduced first below.

[0187] The Internet of Things (IoT) refers to connecting any object to the network through information sensing devices according to agreed protocols. The object exchanges and communicates information through information dissemination media to achieve functions such as intelligent identification, positioning, tracking, and supervision. In recent years, the Internet of Things has attracted wide attention in the field of wireless communication technologies, and more and more "things" are connected to each other through the Internet of Things to improve productivity efficiency and living comfort.

[0188] However, with the wide application of ambient Internet of Things (A-IoT) devices, in the case of dense deployment of A-IoT devices, there is serious communication interference between A-IoT devices, resulting in low communication efficiency.

[0189] Therefore, how to solve the communication interference between A-IoT devices has become a key research topic for those skilled in the art.

[0190] In view of this, in the embodiments of the present application, a new communication method is provided, which can achieve effective transmission resource allocation, solve the communication interference between A-IoT devices, and improve communication efficiency.

[0191] Please refer to Figure 2 , Figure 2Schematic flowchart of a communication method provided by an embodiment of this application. This communication method is applied to the field of communication technologies, such as communication in scenarios where multiple A-IoT devices are densely deployed. It can be understood that this communication method can be executed by a communication device, which can be a network device, or a chip (system) or circuit for a network device. This application does not make any limitations in this regard. This communication method includes but is not limited to the following steps:

[0192] S201: The network device sends the first information to the terminal device. Correspondingly, the terminal device receives the first information.

[0193] S202: Based on the first information, the terminal device transmits information periodically according to the first transmission resource configuration information, or transmits information aperiodically according to the second transmission resource configuration information.

[0194] It can be understood that the network device in the embodiment of this application is a device equipped with a processor that can be used to execute computer-executable instructions, and can be an access network device, such as a base station, a transmission point TRP, etc. Specifically, it can be the above-mentioned Figure 1 access network device (including but not limited to any one of base station 1 and base station 2) in, which is used to execute the communication method in the embodiment of this application to achieve effective transmission resource allocation, solve the communication interference between A-IoT devices, and improve communication efficiency.

[0195] It can be understood that the terminal device in the embodiment of this application is a device equipped with a processor that can be used to execute computer-executable instructions, and can be a handheld terminal (such as a mobile phone, a tablet computer, etc.), or a vehicle-mounted terminal (such as a wireless terminal in unmanned driving, etc.). Specifically, it can also be the above-mentioned Figure 1 terminal device (including but not limited to any one of UE1 to UE8, A-IoT device1 to A-IoT device 2) in, which is used to participate in executing the communication method in the embodiment of this application to achieve effective transmission resource allocation, solve the communication interference between A-IoT devices, and improve communication efficiency.

[0196] Among them, the first information in the embodiment of this application is used to instruct the terminal device to transmit information periodically according to the first transmission resource configuration information, or to transmit information aperiodically according to the second transmission resource configuration information. Correspondingly, after receiving the first information, the terminal device will, according to the instruction of the first information, transmit information periodically according to the first transmission resource configuration information, or transmit information aperiodically according to the second transmission resource configuration information.

[0197] Optionally, the terminal device transmits information according to the instruction of the first information, which can be to send information or to receive information. This application does not make any limitations in this regard.

[0198] Currently, in the case of intensive deployment of A-IoT devices, there is serious communication interference between A-IoT devices, resulting in low communication efficiency.

[0199] In the embodiments of the present application, by instructing the terminal device to transmit information periodically according to the first transmission resource configuration information or transmit information aperiodically according to the second transmission resource configuration information, effective transmission resource allocation can be achieved. When applied to the case of intensive deployment of multiple A-IoT devices, by effectively allocating transmission resources to multiple A-IoT devices, communication interference between A-IoT devices can be solved and communication efficiency can be improved.

[0200] Optionally, the above first information may be carried in any one of the following messages:

[0201] System Information Block (SIB), Radio Resource Control (RRC) signaling, Media Access Control - Control Element (MAC-CE).

[0202] The following is a description by cases based on different indication contents of the first information:

[0203] Case 1:

[0204] The first information is used to instruct the terminal device to transmit information periodically according to the first transmission resource configuration information.

[0205] In a possible embodiment, the first transmission resource configuration information includes at least two of the following:

[0206] Identification information corresponding to the transmission mode, time domain information corresponding to the transmission mode, frequency domain information corresponding to the transmission mode.

[0207] It can be understood that the first transmission resource configuration information includes but is not limited to at least two of the identification information, time domain information, and frequency domain information corresponding to the transmission mode. Through the above at least two pieces of information, the transmission mode and the corresponding transmission resources can be uniquely determined to achieve effective transmission resource allocation.

[0208] Optionally, the time domain information corresponding to the transmission mode includes at least one of the following:

[0209] The length of the transmission period corresponding to one or more transmission modes, the starting position offset value of the transmission period, the correspondence between one or more transmission time periods within the transmission period and the transmission mode.

[0210] It can be understood that the time-domain information corresponding to the transmission mode includes, but is not limited to, at least one of the length of the transmission period corresponding to one or more transmission modes, the starting position offset value of the transmission period, and the correspondence between one or more transmission time periods within the transmission period and the transmission mode. Through the above at least one piece of information, the transmission mode and the corresponding time-domain resources can be determined to achieve effective transmission resource allocation.

[0211] Optionally, the correspondence between one or more transmission time periods within the transmission period and the transmission mode can be implemented in the form of a bitmap.

[0212] Exemplarily, assume that five transmission modes are set within a transmission period, namely transmission mode 1, transmission mode 2, transmission mode 3, transmission mode 4, and transmission mode 5, and a transmission period includes five time periods, namely time period 1, time period 2, time period 3, time period 4, and time period 5. Then the correspondence between each transmission mode and each time period is that transmission mode 1 corresponds to time period 1, transmission mode 2 corresponds to time period 2, transmission mode 3 corresponds to time period 3, transmission mode 4 corresponds to time period 4, and transmission mode 5 corresponds to time period 5. Specifically, it is shown in Table 1 below:

[0213] Table 1

[0214]

[0215]

[0216] As can be seen from Table 1, when a transmission period is a radio frame (10 ms), each time period is a sub-frame (1 ms), one transmission mode corresponds to one time period, and different transmission modes correspond to different time periods respectively.

[0217] Exemplarily, assume that five transmission modes are set within a transmission period, namely transmission mode 1, transmission mode 2, transmission mode 3, transmission mode 4, and transmission mode 5, and a transmission period includes seven time periods, namely time period 1, time period 2, time period 3, time period 4, time period 5, time period 6, and time period 7. Then the correspondence between each transmission mode and each time period is that transmission mode 1 corresponds to time period 1, transmission mode 2 corresponds to time period 2, transmission mode 3 corresponds to time period 3, transmission mode 4 corresponds to time period 4 and time period 5, and transmission mode 5 corresponds to time period 6 and time period 7. Specifically, it is shown in Table 2 below:

[0218] Table 2

[0219]

[0220] As can be seen from Table 2, when a transmission period is one radio frame (10 ms), each time period is one sub-frame (1 ms). Among them, some transmission modes respectively correspond to one time period, such as Transmission Mode 1, Transmission Mode 2, and Transmission Mode 3. Some other transmission modes respectively correspond to multiple time periods, such as Transmission Mode 4 and Transmission Mode 5. And different transmission modes respectively correspond to different time periods.

[0221] Based on the time-domain information corresponding to the above transmission modes, the time-domain resources corresponding to them can be uniquely determined based on the transmission mode, realizing effective transmission resource allocation.
