Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and related devices. Background Art

[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

It is understood that the 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 method includes:

[0008] First information is sent to a terminal device, wherein the first information includes configuration information of at least one transmission resource set, each transmission resource set in the at least one transmission resource set includes at least one transmission channel, and the first information is used to instruct the terminal device to select one or more transmission resource sets from the at least one transmission resource set, and to select one or more transmission channel transmission information from the one or more transmission resource sets.

[0009] In an embodiment of the present application, a communication method is provided in which a network device sends first information to a terminal device, and the terminal device receives the first information accordingly. The network device and / or terminal device herein may also be a processor / chip capable of executing computer-executable instructions, and this embodiment of the present application is not limited thereto.

[0010] In the embodiment of the present application, the first information includes configuration information of at least one transmission resource set, and each transmission resource set in the at least one transmission resource set includes at least one transmission channel. The first information is used to instruct the terminal device to select one or more transmission resource sets from the at least one transmission resource set, and to select one or more transmission channel transmission information from the one or more transmission resource sets. Accordingly, after receiving the first information, the terminal device will first select one or more transmission resource sets from the at least one transmission resource set included in the first information, and then select one or more transmission channel transmission information from the one or more transmission resource sets, according to the instruction of the first 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.

[0012] In an embodiment of the present application, effective transmission resource allocation can be achieved by instructing the terminal device to select one or more transmission channels from at least one transmission resource set to transmit information through the first information. When applied to a situation 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.

It can be understood that, assuming that any one of the transmission resource sets included in the first information is called a first transmission resource set, and any one of the transmission channels included in the first transmission resource set is called a first transmission channel, then the time-frequency resources in the first transmission channel are included in the time-frequency resources in the first transmission resource set.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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".

[0128] 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.

[0129] 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.

[0130] Please refer to FIG1 , which is a schematic diagram of a communication system provided in an embodiment of the present application.

[0131] As shown in FIG1 , the communication system may include at least one access network device and at least one terminal device.

[0132] The introductions to access network equipment and terminal equipment are as follows:

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] For ease of description, the following will take the terminal device as UE as an example to introduce the method involved in this application.

[0139] As shown in FIG1 , the communication system may further include at least one core network device. The core network device is described as follows:

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] Therefore, how to solve the communication interference between A-IoT devices has become a key research topic for those skilled in the art.

[0150] 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.

[0151] 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:

[0152] S201: The network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information.

[0153] S202: The terminal device selects one or more transmission resource sets from at least one transmission resource set based on the first information, and selects one or more transmission channel transmission information from the one or more transmission resource sets.

[0154] 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.

[0155] 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, etc.), etc. Specifically, it can also be the terminal device in Figure 1 and / or Figure 2 above (including but not limited to any device such as UE1 to UE8), 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.

[0156] In the embodiment of the present application, the first information includes configuration information of at least one transmission resource set, and each transmission resource set in the at least one transmission resource set includes at least one transmission channel. The first information is used to instruct the terminal device to select one or more transmission resource sets from the at least one transmission resource set, and to select one or more transmission channel transmission information from the one or more transmission resource sets. Accordingly, after receiving the first information, the terminal device will first select one or more transmission resource sets from the at least one transmission resource set included in the first information, and then select one or more transmission channel transmission information from the one or more transmission resource sets according to the instruction of the first information.

[0157] 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.

[0158] Currently, with the dense deployment of A-IoT devices, there is serious communication interference between A-IoT devices, resulting in low communication efficiency.

[0159] In an embodiment of the present application, effective transmission resource allocation can be achieved by instructing the terminal device to select one or more transmission channels from at least one transmission resource set to transmit information through the first information. When applied to a situation 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.

[0160] Optionally, the first information may be carried in any of the following messages:

[0161] Radio resource control (RRC) signaling, media access control control element (MAC-CE).

[0162] It can be understood that the network device can carry the first information to the terminal device through signaling such as RRC or MAC-CE to instruct the terminal device to periodically select one or more transmission resource sets from at least one transmission resource set, and select one or more transmission channels from one or more transmission resource sets to transmit information.

[0163] In a possible embodiment, the configuration information of the at least one transmission resource set includes:

[0164] Each transmission resource set corresponds to M frequency domain resource units and N time domain resource units, and each transmission channel corresponds to P frequency domain resource units and Q time domain resource units, where M and N are integers greater than or equal to 1, P and Q are integers greater than or equal to 1, and P is less than or equal to M, and Q is less than or equal to N.

[0165] Optionally, the frequency domain resource unit may be a resource block (RB), a subband, or a subcarrier, which is not limited in the embodiment of the present application.

[0166] Optionally, the time domain resource unit may be a system frame, a subframe, a time slot, or an orthogonal frequency division multiplexing (OFDM) symbol, which is not limited in the embodiment of the present application.

[0167] Exemplarily, a transmission resource set includes 2 subbands and 40 time slots, and a transmission channel includes 1 subband and 5 time slots.

[0168] It can be understood that effective transmission resource allocation can be achieved through the configuration information of at least one transmission resource set in the embodiments of the present application.

[0169] In a possible embodiment, the N time domain resource units and / or the Q time domain resource units are set periodically.

[0170] It can be understood that the N time domain resource units corresponding to each transmission resource set and / or the Q time domain resource units corresponding to each transmission channel are set periodically.

[0171] Through the periodically set time domain resource units in the embodiments of the present application, the terminal device can periodically transmit information on one or more selected transmission channels, reduce signaling overhead, and achieve effective transmission resource allocation.

[0172] In a possible embodiment, the communication method in the embodiment of the present application may further perform the following step S203:

[0173] The network device sends the second information to the terminal device, and correspondingly, the terminal device receives the second information from the network device.

[0174] The second information is used to indicate that the time-frequency resources in the transmission channel are included in the time-frequency resources in the transmission resource set where the transmission channel is located.

[0175] It can be understood that, assuming that any transmission resource set included in the first information is called a first transmission resource set, and any transmission channel included in the first transmission resource set is called a first transmission channel, then the time-frequency resources in the first transmission channel are included in the time-frequency resources in the first transmission resource set.

[0176] Optionally, the second information may be carried in any of the following messages:

[0177] Radio resource control (RRC) signaling, media access control control element (MAC-CE).

[0178] Optionally, the second information and the first information may be carried in different messages or in different fields of the same message, and this embodiment of the present application does not impose any restrictions on this.

[0179] Through the embodiments of the present application, the time-frequency resources corresponding to the transmission channels in each transmission resource set can be determined, thereby achieving effective transmission resource allocation.

[0180] In a possible embodiment, the communication method in the embodiment of the present application may further perform the following step S204:

[0181] The network device sends the third information to the terminal device, and correspondingly, the terminal device receives the third information from the network device.

[0182] The third information is used to indicate activation or deactivation of one or more transmission resource sets in at least one transmission resource set.

[0183] Optionally, the third information includes identification information corresponding to one or more transmission resource sets, which is used to indicate activation or deactivation of the one or more transmission resource sets.

[0184] Optionally, the third information may be carried in a media access control control element (MAC-CE) to indicate activation or deactivation of one or more transmission resource sets in at least one transmission resource set.

[0185] Optionally, the third information, the second information and the first information may be carried in different messages or in different fields of the same message, and this embodiment of the present application does not impose any restrictions on this.

[0186] Through the embodiments of the present application, one or more transmission resource sets in at least one transmission resource set can be activated to achieve effective transmission resource allocation. When applied to the situation 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.

[0187] In a possible embodiment, the communication method in the embodiment of the present application may further perform the following step S205:

[0188] The network device sends the fourth information to the terminal device, and correspondingly, the terminal device receives the fourth information from the network device.

[0189] The fourth information indicates the number of transmission channels allowed to be occupied, the proportion of transmission channels allowed to be occupied, or other information on transmission channel occupation rights of each activated transmission resource set in at least one transmission resource set.

[0190] Optionally, the fourth information, the third information, the second information and the first information may be carried in different messages or in different fields of the same message, and this embodiment of the present application does not impose any restrictions on this.

[0191] Through the embodiments of the present application, it is not necessary to send indication information every time to tell the terminal which transmission channel to occupy. Instead, the terminal itself decides which transmission channel to occupy to transmit information, which can reduce signaling overhead and achieve effective transmission resource allocation.

[0192] Optionally, the terminal device selects one or more transmission channels from one or more transmission resource sets to transmit information, which may be implemented in, but not limited to, the following ways:

[0193] Method 1:

[0194] After receiving the first information, the terminal device randomly selects L transmission channels from the K transmission channels included in the one or more transmission resource sets to transmit information according to the instruction of the first information. The time-frequency domain positions of the L transmission channels can be continuous or discontinuous, which is not limited in this embodiment of the present application.

[0195] It can be understood that randomly selecting L transmission channel transmission information from the K transmission channels included in one or more transmission resource sets can be understood as selecting L transmission channel transmission information from the K transmission channels included in one or more transmission resource sets with equal probability.

[0196] It can be understood that the selected L transmission channels do not exceed the number of transmission channels allowed to be occupied or do not exceed the proportion of transmission channels allowed to be occupied.

[0197] Through the embodiments of the present application, it is not necessary to send indication information every time to tell the terminal which transmission channel to occupy. Instead, the terminal itself decides which transmission channel to occupy to transmit information, which can reduce signaling overhead and achieve effective transmission resource allocation.

[0198] Method 2:

[0199] After the terminal device receives the first information, it selects L transmission channel transmission information from the K transmission channels included in one or more transmission resource sets based on the indication of the first information and the identification of the terminal device. The time-frequency domain positions of the L transmission channels can be continuous or discontinuous, and the embodiments of the present application do not impose any restrictions on this.

[0200] It can be understood that the selected L transmission channels do not exceed the number of transmission channels allowed to be occupied or do not exceed the proportion of transmission channels allowed to be occupied.

[0201] Optionally, in the second embodiment, the indexes corresponding to the L transmission channels selected from the K transmission channels included in the one or more transmission resource sets according to the identifier of the terminal device must meet the following conditions:

[0202] in, represents the number of selections for selecting L transmission channels from K transmission channels, mod is a modulo operation, ID represents the identifier of the terminal device, f(ID) represents the output value corresponding to the input of the identifier of the terminal device into the function f(), and index is the index of the combination scheme for selecting L transmission channels from K transmission channels.

[0203] It can be understood that selecting L transmission channels from K transmission channels corresponds to Combination schemes, number the possible combination schemes of L transmission channels Each number represents one of the possible combinations of L transmission channels. The terminal device identifier is input into the function f() to obtain an output value, which is then compared with the number of combinations. The remainder of the L transmission channel combination scheme is used as the index of the possible selection, that is, the number A possible combination scheme of L transmission channels.

[0204] For example, assuming K=4, L=2, then selecting 2 transmission channels from 4 transmission channels (A, B, C, D) corresponds to There are several possible combinations. The possible combinations of two transmission channels are numbered [0, 1, 2, 3, 4, 5]. Each number represents one of the possible combinations of two transmission channels. For example, number 0 represents the combination of transmission channels A and B, number 1 represents the combination of transmission channels A and C, number 2 represents the combination of transmission channels A and D, number 3 represents the combination of transmission channels B and C, number 4 represents the combination of transmission channels B and D, and number 5 represents the combination of transmission channels C and D. Assume that the terminal device identifier is input into the function f() and an output value of 10 is obtained. Then the output value 10 is compared with the number of combination solutions. The remainder 4 is taken as the index of the possible combination of the two transmission channels. That is, the combination of transmission channels B and D is selected with number 4 in the number [0, 1, 2, 3, 4, 5]. In this case, transmission channels B and D are selected from the four transmission channels (A, B, C, D) based on the terminal device identifier to transmit information.

[0205] Through the embodiments of the present application, it is not necessary to send indication information every time to tell the terminal which transmission channel to occupy. Instead, the terminal itself decides which transmission channel to occupy to transmit information, which can reduce signaling overhead and achieve effective transmission resource allocation.

[0206] It should be understood that the above-mentioned methods 1 and 2 are merely two possible examples for explaining the selection of one or more transmission channels and should not be used to limit the embodiments of the present application. New methods obtained by reasonable variations, supplements, or combinations of the above-mentioned methods 1 and 2 fall within the scope of protection of this application.

[0207] Optionally, the terminal devices in the embodiments of the present application include but are not limited to Internet of Things (IoT) terminals. When the communication method in the embodiments of the present application is applied to a situation 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.

[0208] Please refer to Figure 3, which is a flow chart of another communication method provided in an embodiment of the present application. It is understandable that the steps in the embodiment of the present application can be regarded as reasonable variations or supplements to the embodiment in Figure 2 above; or, it is understandable that the communication method in the embodiment of the present application can also be regarded as an embodiment that can be executed independently, and the present application does not limit this. The communication method provided in the embodiment of the present application is applied to the field of communication technology, such as communication in a scenario where multiple A-IoT devices are densely deployed.

[0209] It can be understood that the network equipment involved in the communication method provided in the embodiment of the present application can refer to the network equipment in the communication method shown in Figure 2 above, and the terminal equipment involved in the communication method provided in the embodiment of the present application can refer to the terminal equipment in the communication method shown in Figure 2 above, and they will not be repeated here.

[0210] The communication method includes but is not limited to the following steps:

[0211] S301: The network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information.

[0212] This is consistent with step S201 in the embodiment shown in FIG2 , and will not be described again here.

[0213] S302: The network device sends second information to the terminal device, and correspondingly, the terminal device receives the second information.

[0214] This is consistent with step S203 in the embodiment shown in FIG2 , and will not be described again here.

[0215] S303: The network device sends third information to the terminal device, and correspondingly, the terminal device receives the third information.

[0216] This is consistent with step S204 in the embodiment shown in FIG2 , and will not be described again here.

[0217] S304: The network device sends fourth information to the terminal device, and correspondingly, the terminal device receives the fourth information.

[0218] This is consistent with step S205 in the embodiment shown in FIG2 , and will not be described again here.

[0219] S305: The terminal device selects one or more transmission resource sets from at least one transmission resource set, and selects one or more transmission channels from the one or more transmission resource sets to transmit information.

[0220] Specifically, the terminal device randomly selects L transmission channel transmission information from the K transmission channels included in one or more transmission resource sets, or selects L transmission channel transmission information from the K transmission channels included in one or more transmission resource sets based on the identification of the terminal device.

[0221] It can be understood that in the embodiment of the present application, effective transmission resource allocation can be achieved by instructing the terminal device to select one or more transmission channels from at least one transmission resource set to transmit 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.
