[0003] The Internet of Things (IoT) refers to the connection of any object to a network through information sensing devices and agreed-upon protocols. Objects exchange and communicate information through information transmission media to achieve intelligent identification, positioning, tracking, and monitoring functions. In recent years, the IoT has attracted widespread attention in the field of wireless communication technology. More and more "things" are being connected through the IoT to improve productivity and enhance living comfort.

[0004] However, with the widespread application of ambient internet of things (A-IoT) devices, when A-IoT devices are densely deployed, there is serious communication interference between A-IoT devices, resulting in low communication efficiency.

[0005] Therefore, how to solve the communication interference between A-IoT devices has become a key research topic for those skilled in the art. Summary of the Invention

Accordingly, after receiving the first information, the terminal device will, in accordance with the instruction of the first information, periodically transmit information according to the first transmission resource configuration information, or aperiodically transmit information according to the second transmission resource configuration information.

[0011] Currently, with the dense deployment of A-IoT devices, there is serious communication interference between A-IoT devices, resulting in low communication efficiency.

[0160] In order to make the purpose, technical solutions and advantages of this application clearer, the embodiments of this application will be described below in conjunction with the drawings in the embodiments of this application.

[0161] The terms "first" and "second" in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to the process, method, product, or device.

[0162] The “embodiment” mentioned herein means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be understood explicitly and implicitly by those skilled in the art that in the various embodiments of the present application, unless otherwise specified and there is a logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their inherent logical relationship.

[0163] It should be understood that in the present application, "at least one (item)" refers to one or more, "more than one" refers to two or more, "at least two (items)" refers to two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least 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.

[0164] It should be noted that in this application, "indication" can include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0165] In this application, the information indicated by the indication information is referred to as the information to be indicated. In specific implementations, 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 an index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, where the other information is associated with the information to be indicated. Alternatively, only a portion of the information to be indicated can be indicated, while the rest of the information to be indicated is known or agreed upon in advance. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-specified) order of the various information, thereby reducing indication overhead to a certain extent. The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. The transmission period and / or transmission timing of these sub-information can be the same or different. The specific transmission method is not limited in this application. The transmission period and / or transmission timing of these sub-information can be pre-defined, for example, according to a protocol, or can be configured by the transmitting device sending configuration information to the receiving device.

[0166] 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, A is the destination, and does not limit "sending information to A" to direct transmission on the air interface. "Sending information to A" includes sending information directly to A, and also includes sending information indirectly to A through a transmitter, so "sending information to A" can also be understood as "outputting information to A". Similarly, "receiving information from A" indicates that the source of the information is A, including receiving information directly from A, and also including receiving information indirectly from A through a receiver, so "receiving information from A" can also be understood as "inputting information from A".

[0167] The method provided in this application can be applied to various communication systems, for example, the Internet of Things (IoT) system, the narrowband Internet of Things (NB-IoT) system, the long term evolution (LTE) system, the fifth generation (5G) communication system, and new communication systems (such as 6G) that will emerge in future communication developments.

[0168] The technical solution provided in 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 Internet of Vehicles. Among them, the communication mode in the Internet of Vehicles system is collectively referred to as vehicle-to-everything (V2X, 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. For example, in Figure 1 shown below, terminal devices can communicate with each other through D2D technology, M2M technology or V2X technology, etc.

[0169] Please refer to FIG1 , which is a schematic diagram of a communication system provided in an embodiment of the present application.

[0170] As shown in FIG1 , the communication system may include at least one access network device and at least one terminal device.

[0171] The introductions to access network equipment and terminal equipment are as follows:

[0172] 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 communications. The access network device may be any device with wireless transceiver capabilities, 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 a sixth-generation communication system. Optionally, the access network device may be an access node, wireless relay node, wireless backhaul node, etc. in a wireless local area network (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 an in-vehicle device. Optionally, the access network device may also be a small cell, a transmission reception point (TRP) (or also referred to as a transmission point), etc. It is understood that the access network device may also be a base station in a future evolved public land mobile network (PLMN), etc.

[0173] In some deployments, a base station (such as a gNB) may be composed of a centralized unit (CU) and a distributed unit (DU). This means that 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 the DU. Multiple DUs share a single CU, which can save costs and facilitate network expansion. In other base station deployments, the CU can be further divided into a CU-control plane (CP) and a CU-user plane (UP). In still other base station deployments, the base station may be an antenna unit (RU), etc. In still other base station deployments, the base station may also be an open radio access network (ORAN) architecture, etc. This application does not limit the specific type of base station. For example, when the base station is an ORAN architecture, the base station shown in the embodiments of this application may be an access network device in the ORAN, or a module in the access network device, etc. In the ORAN system, CU may also be referred to as open (O)-CU, DU may also be referred to as O-DU, CU-DU may also be referred to as O-CU-DU, CU-UP may also be referred to as O-CU-UP, and RU may also be referred to as O-RU.

[0174] For ease of description, the following will take the access network device as a base station as an example to introduce the method involved in this application.

[0175] Exemplarily, the terminal device may also be referred to as user equipment (UE), a terminal, or the like. A terminal device is a device with wireless transceiver capabilities that can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; on water, such as on a ship; or in the air, such as on an airplane, balloon, or satellite. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, 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 care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, or the like. It is understood that the terminal device may also be a terminal device in a future 6G network or a terminal device in a future evolved PLMN.

[0176] It can be understood that the terminal device shown in this application can not only include vehicles in the Internet of Vehicles (such as complete vehicles), but also include vehicle-mounted devices or vehicle-mounted terminals in the Internet of Vehicles. This application does not limit the specific form of the terminal device when applied to the Internet of Vehicles.

[0177] For ease of description, the following will take the terminal device as UE as an example to introduce the method involved in this application.

[0178] As shown in FIG1 , the communication system may further include at least one core network device. The core network device is described as follows:

[0179] Exemplarily, the core network equipment includes services such as user access control, mobility management, session management, user security authentication, and billing. It consists of multiple functional units, which can be divided into functional entities on the control plane and data plane. 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 location service requests of the target terminal and processing location-related information. The user plane function (UPF) is responsible for managing user plane data transmission, traffic statistics, and other functions.

[0180] The communication system shown in Figure 1 includes a core network device, two base stations, and eight UEs, such as the core network device, base station 1 and base station 2, and UE1 to UE8 in Figure 1. 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 method between UEs, reference can be made to the above description and will not be detailed here.

[0181] It should be understood that Figure 1 exemplarily illustrates a core network device, two base stations, and eight UEs, as well as the communication links between the communication devices. Optionally, the communication system may include multiple base stations, and each base station may include another number of UEs within its coverage area, such as a greater or fewer number of UEs, and this application does not limit this.

[0182] Each of the aforementioned communication devices, such as the core network device, base stations 1 and 2, and UEs 1 to 8 in Figure 1 , may be configured with multiple antennas. These multiple antennas may include at least one transmit antenna for sending signals and at least one receive antenna for receiving signals. The embodiments of this application do not limit the specific structure of each communication device. Optionally, the communication system may also include other network entities such as a network controller and a mobility management entity, but the embodiments of this application are not limited thereto.

[0183] It is understandable that the communication system schematic diagram shown in FIG1 is only an example. For other forms of communication system schematic diagrams, reference may be made to relevant standards or protocols, etc., which will not be described in detail here.

[0184] The various embodiments shown below may be applicable to the communication system shown in FIG. 1 , and may also be applicable to other forms of communication systems, which will not be described in detail below.

[0185] This application provides a communication method that is applied to the field of communication technology, such as communication in a scenario where multiple A-IoT devices are densely deployed. To more clearly describe the solution of this application, the following first introduces some knowledge related to A-IoT device communication.

[0186] The Internet of Things (IoT) refers to the connection of any object to a network through information sensing devices and agreed-upon protocols. Objects exchange and communicate information through information transmission media to achieve intelligent identification, positioning, tracking, and monitoring functions. In recent years, the IoT has attracted widespread attention in the field of wireless communication technology. More and more "things" are being connected through the IoT to improve productivity and enhance living comfort.

[0187] However, with the widespread application of ambient internet of things (A-IoT) devices, when A-IoT devices are densely deployed, there is serious communication interference between A-IoT devices, resulting in low communication efficiency.

[0188] Therefore, how to solve the communication interference between A-IoT devices has become a key research topic for those skilled in the art.

[0189] In view of this, an embodiment of the present application provides a new communication method that can achieve effective transmission resource allocation, solve communication interference between A-IoT devices, and improve communication efficiency.

[0190] Please refer to Figure 2, which is a flow chart of a communication method provided in an embodiment of the present application. The communication method is applied to the field of communication technology, such as communication in a scenario where multiple A-IoT devices are densely deployed. It is understandable that the communication method can be performed by a communication device, which can be a network device or a chip (system) or circuit for a network device, and the present application does not limit this. The communication method includes but is not limited to the following steps:

[0191] S201: The network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information.

[0192] S202: The terminal device transmits information periodically according to the first transmission resource configuration information based on the first information, or transmits information aperiodically according to the second transmission resource configuration information.

[0193] It can be understood that the network device in the embodiment of the present application is a device equipped with a processor that can be used to execute computer-executable instructions, which can be an access network device, such as a base station, a transmission point TRP, etc., and specifically can be the access network device in Figure 1 above (including but not limited to any device such as base station 1 and base station 2), which is used to execute the communication method in the embodiment of the present application to achieve effective transmission resource allocation, solve communication interference between A-IoT devices, and improve communication efficiency.

[0194] It can be understood that the terminal device in the embodiment of the present application is a device equipped with a processor that can be used to execute computer instructions. It can be a handheld terminal (such as a mobile phone, tablet computer, etc.), or a vehicle-mounted terminal (such as a wireless terminal in an unmanned driving vehicle, etc.), etc. Specifically, it can also be the terminal device in the above Figure 1 (including but not limited to any device such as UE1 to UE8, A-IoT device 1 to A-IoT device 2), which is used to participate in the execution of the communication method in the embodiment of the present application to achieve effective transmission resource allocation, solve communication interference between A-IoT devices, and improve communication efficiency.

[0195] The first information in the embodiment of the present application is used to instruct the terminal device to periodically transmit information according to the first transmission resource configuration information, or to aperiodically transmit information according to the second transmission resource configuration information. Accordingly, after receiving the first information, the terminal device will, in accordance with the instruction of the first information, periodically transmit information according to the first transmission resource configuration information, or aperiodically transmit information according to the second transmission resource configuration information.

[0196] Optionally, the terminal device transmits information according to the instructions of the first information, which may be sending information or receiving information, and the embodiments of the present application do not limit this.

[0197] Currently, with the dense deployment of A-IoT devices, there is serious communication interference between A-IoT devices, resulting in low communication efficiency.

[0198] In the embodiment of the present application, effective transmission resource allocation can be achieved by instructing the terminal device to transmit information periodically according to the first transmission resource configuration information, or to transmit information non-periodically according to the second transmission resource configuration information through the first information. When applied to the case where multiple A-IoT devices are densely deployed, by effectively allocating transmission resources to multiple A-IoT devices, communication interference between A-IoT devices can be resolved and communication efficiency can be improved.

[0199] Optionally, the first information may be carried in any of the following messages:

[0200] System information block (SIB), radio resource control (RRC) signaling, media access control control element (MAC-CE).

[0201] The following describes different situations based on the different indication contents of the first information:

[0202] Case 1:

[0203] The first information is used to instruct the terminal device to periodically transmit information according to the first transmission resource configuration information.

[0204] In a possible embodiment, the first transmission resource configuration information includes at least two of the following:

[0205] Identification information corresponding to the transmission mode, time domain information corresponding to the transmission mode, and frequency domain information corresponding to the transmission mode.

[0206] It can be understood that the first transmission resource configuration information includes but is not limited to at least two items of identification information, time domain information, and frequency domain information corresponding to the transmission mode. Through the above at least two items of information, the transmission mode and the corresponding transmission resources can be uniquely determined to achieve effective transmission resource allocation.

[0207] Optionally, the time domain information corresponding to the transmission mode includes at least one of the following:

[0208] The length of the transmission cycle corresponding to one or more transmission modes, the starting position offset value of the transmission cycle, and the correspondence between one or more transmission time periods within the transmission cycle and the transmission mode.

[0209] It can be understood that the time domain information corresponding to the transmission mode includes but is not limited to the length of the transmission period corresponding to one or more transmission modes, the starting position offset value of the transmission period, and at least one of the correspondences between one or more transmission time periods within the transmission period and the transmission mode. Through the above at least one item of information, the transmission mode and the corresponding time domain resources can be determined to achieve effective transmission resource allocation.

[0210] Optionally, a bitmap may be used to implement the correspondence between one or more transmission time periods within a transmission cycle and the transmission mode.

[0211] For example, assuming that five transmission modes are set within a transmission cycle, namely transmission mode 1, transmission mode 2, transmission mode 3, transmission mode 4, and transmission mode 5, and that a transmission cycle includes five time periods, namely time period 1, time period 2, time period 3, time period 4, and time period 5, then the corresponding relationship between each transmission mode and each time period is 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. The details are shown in Table 1 below:

[0212] Table 1

[0213] As can be seen from Table 1, when a transmission cycle is a radio frame (10 ms), each time period is a subframe (1 ms), one transmission mode corresponds to one time period, and different transmission modes correspond to different time periods.

[0214] For example, assuming that five transmission modes are set within a transmission cycle, namely transmission mode 1, transmission mode 2, transmission mode 3, transmission mode 4, and transmission mode 5, and that a transmission cycle 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 corresponding relationship 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. The details are shown in Table 2 below:

[0215] Table 2

[0216] As can be seen from Table 2, when a transmission period is a radio frame (10ms), each time period is a subframe (1ms). Some transmission modes correspond to one time period, such as transmission mode 1, transmission mode 2, and transmission mode 3. Other transmission modes correspond to multiple time periods, such as transmission mode 4 and transmission mode 5, and different transmission modes correspond to different time periods.

[0217] By using the time domain information corresponding to the above transmission mode, the time domain resources corresponding to the transmission mode can be uniquely determined based on the transmission mode, thereby achieving effective transmission resource allocation.

[0218] Optionally, the transmission period includes multiple time units, and the starting position offset value of the transmission period satisfies the following relationship: Offset = (2 μ ×10n f +n s)mod T;

[0219] Wherein, Offset represents the starting position offset value of the above transmission period, μ represents the parameter of the subcarrier spacing in the system frame, and n f Indicates the sequence number of the system frame, n s Indicates the sequence number of the time unit within the system frame.

[0220] It can be understood that the transmission cycle includes multiple time units, and the starting position offset value of the transmission cycle (i.e., the starting time unit of the transmission cycle) satisfies the above relationship, which can realize the correspondence between one or more transmission time periods and the transmission mode within the transmission cycle, thereby realizing effective transmission resource allocation.

[0221] Optionally, the time unit may be a time slot, a radio frame, or an orthogonal frequency division multiplexing (OFDM) symbol, which is not limited in the embodiment of the present application.

[0222] Optionally, the starting position offset value of the above-mentioned transmission period can be configured by the network device or pre-configured through a protocol, and the embodiment of the present application does not impose any limitation on this.

[0223] Optionally, the parameter μ of the subcarrier spacing within the above system frame may be specifically referred to Section 4.2 of the protocol 3GPP TS 38.211, as shown in Table 3 below:
