[0122] In order to make the objectives, technical solutions, and advantages of the present application clearer, the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0123] The terms "first" and "second" in the description, claims, and drawings of the present application 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, or optionally further includes other steps or units inherent to these processes, methods, products, or devices, etc.

[0124] As used herein, "embodiment" means that the specific features, structures, or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears at various places in the specification and 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 the present application, if there is no special description and 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 new embodiments according to their inherent logical relationships.

[0125] It should be understood that, in the present 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 may exist. For example, "A and / or B" may 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 indicates that the associated objects before and after are in an "or" relationship. "At least one (one) of the following" or its similar expression means 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 may 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.

[0126] It should be noted that, in the present application, "indicate" 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 the indication information carries A, directly indicates A, or indirectly indicates A.

[0127] 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 implement the indication of specific information by means of the arrangement order of each piece of information pre-agreed (such as protocol regulations), thereby reducing the 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, and the sending periods and / or sending times 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 times 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.

[0128] 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 including indirectly receiving information from A through a receiver. Therefore, "receive information from A" can also be understood as "input information from A".

[0129] 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) emerging in the future development of communication.

[0130] 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. Among them, the communication methods in the V2X network system 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.

[0135] 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 one CU and the remaining functions deployed in the 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 can also be a radio unit (RU), etc. In some other deployments of the base station, the base station can 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 can also be called an open (O)-CU, the DU can also be called an O-DU, the CU-DU can also be called an O-CU-DU, the CU-UP can also be called an O-CU-UP, and the RU can also be called an O-RU.

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.

[0138] It can be understood that the terminal device shown in this application can not only include a vehicle in the vehicle-to-everything (V2X) network (such as a whole vehicle), but also include in-vehicle devices or in-vehicle terminals in the V2X network, etc. This application does not limit the specific form of the terminal device when it is applied to the V2X network.

[0139] For ease of description, in the following, the terminal device is taken as an example of a UE to introduce the method involved in this application.

[0141] 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.

[0142] 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.

[0143] 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.

The multiple antennas can include at least one transmit antenna for transmitting signals and at least one receive antenna for receiving signals, etc. The embodiments of the present application do not limit the specific structures of the respective communication devices. Optionally, the communication system may further include other network entities such as a network controller and a mobility management entity, which are not limited in the embodiments of the present application.

[0145] 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.

[0146] 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.

[0147] The present application provides a communication method, which is applied in 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 the present application, some knowledge related to the communication of A-IoT devices will be introduced first below.

[0148] The Internet of Things (IoT) refers to connecting any object to a network through information sensing devices according to an agreed protocol, and the object exchanges and communicates information through an information dissemination medium 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 technology, and more and more "things" are connected to each other through the Internet of Things to improve productivity efficiency and living comfort.

[0149] 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.

[0150] Therefore, how to solve the communication interference between A-IoT devices has become a key research topic for those skilled in the art.

[0151] 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.

[0152] Please refer to Figure 2 , Figure 2Schematic diagram of a communication method provided by an embodiment of the present 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. The present application does not limit this. This communication method includes but is not limited to the following steps:

[0153] S201: The network device sends the first information to the terminal device. Correspondingly, the terminal device receives the first information.

[0154] S202: Based on the first information, 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 selected transmission resource sets to transmit information.

[0155] It can be understood that the network device in the embodiment of the present application is a device equipped with a processor that can 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) for executing 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] It can be understood that the terminal device in the embodiment of the present application is a device equipped with a processor that can 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 and / or Figure 2 terminal device (including but not limited to any one of UE1 to UE8) for participating 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.

[0157] Among them, the first information in the embodiment of the present application 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 select one or more transmission channels from the one or more selected transmission resource sets to transmit information. Correspondingly, after receiving the first information, the terminal device will, according to the indication of the first information, 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 channels from the one or more selected transmission resource sets to transmit information.

[0158] Optionally, the terminal device may transmit information according to the indication of the first information, which may be to send information or to receive information. The embodiments of the present application do not limit this.

[0159] 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.

[0160] In the embodiments of the present application, by indicating the terminal device to select one or more transmission channels from at least one transmission resource set through the first 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, the communication interference between A-IoT devices can be solved and the communication efficiency can be improved.

[0161] Optionally, the above first information may be carried in any of the following messages:

[0162] Radio Resource Control (RRC) signaling, Media Access Control - Control Element (MAC-CE).

[0163] It can be understood that the network device can carry the first information through signaling such as RRC or MAC-CE and send it to the terminal device to indicate that the terminal device periodically selects one or more transmission resource sets from at least one transmission resource set, and selects one or more transmission channels from one or more transmission resource sets to transmit information.

[0164] In a possible embodiment, the configuration information of the above at least one transmission resource set includes:

[0165] M frequency domain resource units and N time domain resource units corresponding to each transmission resource set, P frequency domain resource units and Q time domain resource units corresponding to each transmission channel, 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.

[0166] Optionally, the above frequency domain resource unit may be a resource block (RB), a sub-band, a sub-carrier, and the embodiments of the present application do not limit this.

[0167] Optionally, the above time domain resource unit may be a system frame, a sub-frame, a time slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol, and the embodiments of the present application do not limit this.

[0168] Exemplarily, one transmission resource set includes 2 sub-bands and 40 time slots, and one transmission channel includes 1 sub-band and 5 time slots.

[0169] It can be understood that through the configuration information of at least one transmission resource set in the embodiments of the present application, effective transmission resource allocation can be achieved.

[0170] In a possible embodiment, the above N time domain resource units and / or the above Q time domain resource units are set periodically.

[0171] 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.

[0172] Through the periodically set time domain resource units in the embodiments of the present application, the terminal device can transmit information periodically on one or more selected transmission channels, reducing signaling overhead and achieving effective transmission resource allocation.

[0173] In a possible embodiment, the communication method in the embodiments of the present application may further perform the following step S203:

[0174] The network device sends second information to the terminal device, and correspondingly, the terminal device receives the second information from the network device.

[0175] Wherein, the second information is used to indicate that the time-frequency resources in the transmission channel are included in the time-frequency resources of the transmission resource set where the transmission channel is located.

[0176] It can be understood that assuming that any one transmission resource set included in the first information is called the first transmission resource set, and any one transmission channel included in the first transmission resource set is called the first transmission channel, then the time-frequency resources in the first transmission channel are included in the time-frequency resources of the first transmission resource set.

[0177] Optionally, the above second information may be carried in any one of the following messages:

[0178] Radio Resource Control (RRC) signaling, Media Access Control - Control Element (MAC-CE).

[0179] Optionally, the above second information and the above first information may be carried in different messages, or may be carried in different fields of the same message. The embodiments of the present application do not limit this.

[0180] 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 realizing effective transmission resource allocation.

[0181] In a possible embodiment, the communication method in the embodiments of the present application may further perform the following step S204:

[0182] The network device sends third information to the terminal device. Correspondingly, the terminal device receives the third information from the network device.

[0183] Wherein, the third information is used to indicate the activation or deactivation of one or more transmission resource sets in at least one transmission resource set.

[0184] Optionally, the above-mentioned third information includes identification information corresponding to one or more transmission resource sets, and is used to indicate the activation or deactivation of the one or more transmission resource sets.

[0185] Optionally, the above-mentioned third information may be carried in a media access control control element (MAC-CE) and is used to indicate the activation or deactivation of one or more transmission resource sets in at least one transmission resource set.

[0186] Optionally, the above-mentioned third information, the above-mentioned second information, and the above-mentioned first information may be carried in different messages, or may be carried in different fields of the same message. The embodiments of the present application do not limit this.

[0187] Through the embodiments of the present application, one or more transmission resource sets in at least one transmission resource set can be activated to realize effective transmission resource allocation. When applied to the case of intensive deployment of multiple A-IoT devices, by effectively allocating transmission resources to multiple A-IoT devices, the communication interference between A-IoT devices can be solved and the communication efficiency can be improved.

[0188] In a possible embodiment, the communication method in the embodiments of the present application may further perform the following step S205:

[0189] The network device sends fourth information to the terminal device. Correspondingly, the terminal device receives the fourth information from the network device.

[0190] Wherein, 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 the transmission channel occupancy permission in each activated transmission resource set in at least one transmission resource set.

[0191] Optionally, the above-mentioned fourth information, third information, second information, and first information may be carried in different messages or in different fields of the same message. The embodiments of the present application do not limit this.

[0192] Through the embodiments of the present application, it is not necessary to send indication information to the terminal every time to tell 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.

[0193] Optionally, the terminal device selects one or more transmission channels from one or more transmission resource sets to transmit information. Specifically, it can be implemented by, but not limited to, the following methods:

[0194] Method 1:

[0195] After receiving the first information, the terminal device randomly selects L transmission channels from the K transmission channels included in one or more transmission resource sets to transmit information according to the indication of the first information. The time-frequency domain positions of the L transmission channels may be continuous or discontinuous. The embodiments of the present application do not limit this.

[0196] It can be understood that randomly selecting L transmission channels from the K transmission channels included in one or more transmission resource sets to transmit information can be understood as selecting L transmission channels from the K transmission channels included in one or more transmission resource sets with equal probability to transmit information.

[0197] It can be understood that the selected L transmission channels do not exceed the allowable number of occupied transmission channels or the allowable proportion of occupied transmission channels.

[0198] Through the embodiments of the present application, it is not necessary to send indication information to the terminal every time to tell 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.

[0199] Method 2:

[0200] After receiving the first information, the terminal device selects L transmission channels from the K transmission channels included in one or more transmission resource sets to transmit information based on the identifier of the terminal device according to the indication of the first information. The time-frequency domain positions of the L transmission channels may be continuous or discontinuous. The embodiments of the present application do not limit this.

[0201] It can be understood that the selected L transmission channels do not exceed the allowable number of occupied transmission channels or the allowable proportion of occupied transmission channels.

[0202] Optionally, in the second method, the indexes corresponding to the L transmission channels selected from the K transmission channels included in one or more transmission resource sets according to the identifier of the terminal device need to meet the following conditions:

[0203]

[0204] Among them, represents the number of selections of L transmission channels from K transmission channels, mod is the modulo operation, ID represents the identifier of the above terminal device, f(ID) represents the output value corresponding to inputting the identifier of the above terminal device into the function f( ), and index is the index of the combination scheme of selecting L transmission channels from K transmission channels.

[0205] It can be understood that there are combination schemes for selecting L transmission channels from K transmission channels. The combination schemes of the possible selected L transmission channels are numbered respectively Each number represents one of the possible combination schemes of the selected L transmission channels. After inputting the identifier of the terminal device into the function f( ), an output value is obtained, and then the remainder of this output value divided by the number of combination schemes is used as the index of the combination scheme of the possible selected L transmission channels, that is, one of the combination schemes of the possible selected L transmission channels with the number in.

[0206] Exemplarily, assume K = 4 and L = 2. Then, there are combination schemes for selecting 2 transmission channels from 4 transmission channels (A, B, C, D). The combination schemes of the possible selected 2 transmission channels are numbered [0, 1, 2, 3, 4, 5] respectively. Each number represents one of the possible combination schemes of the selected 2 transmission channels. For example, number 0 represents the combination scheme of selecting transmission channels A and B, number 1 represents the combination scheme of selecting transmission channels A and C, number 2 represents the combination scheme of selecting transmission channels A and D, number 3 represents the combination scheme of selecting transmission channels B and C, number 4 represents the combination scheme of selecting transmission channels B and D, and number 5 represents the combination scheme of selecting transmission channels C and D. Assume that after inputting the identifier of the terminal device into the function f( ), an output value 10 is obtained, and then the remainder of this output value 10 divided by the number of combination schemes 4 is used as the index of the combination scheme of the possible selected 2 transmission channels, that is, the combination scheme of selecting transmission channels B and D with the number 4 in [0, 1, 2, 3, 4, 5]. At this time, based on the identifier of the terminal device, transmission channels B and D are selected from 4 transmission channels (A, B, C, D) to transmit information.

[0207] Through the embodiments of the present application, it is not necessary to send indication information to the terminal every time to tell 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.

[0208] It should be understood that the above-mentioned Method 1 and Method 2 are only used as two possible examples to illustrate the selection of one or more transmission channels, and the embodiments of the present application should not be limited thereby. Any new method obtained by reasonable deformation, supplement or combination based on the above-mentioned Method 1 and Method 2 belongs to the protection scope of the present application.

[0209] Optionally, the terminal device in the embodiments of the present application includes, but is not limited to, an Internet of Things (IoT) terminal. When the communication method in the embodiments of the present application is 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 solved and communication efficiency can be improved.

[0210] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of another communication method provided by the embodiments of the present application. It can be understood that the steps in the embodiments of the present application can be regarded as reasonable deformations or supplements of the embodiments in the above Figure 2 ; or it can be understood that the communication method in the embodiments 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 by the embodiments of the present application is applied to the field of communication technologies, such as communication in the scenario where multiple A-IoT devices are densely deployed.
