[0038] To facilitate understanding, before introducing the embodiments of this disclosure, the following explanations are provided for several terms involved in the embodiments of this disclosure:

[0039] Ambient IoT, also known as the Internet of Things for the Environment, does not require batteries or power sources. Instead, it obtains energy from the environment or radio frequency signals to modulate and transmit its waveform.

[0040] Preamble: The preamble signal, also known as the preamble synchronization code, is used to obtain the synchronization position in asynchronous transmission. It is generally located at the beginning of the transmitted signal.

[0041] Midamble: An intermediate synchronization code, also known as an intermediate synchronization code, is used to correct or align synchronization in the middle of asynchronous transmission. It is generally located in the middle of the transmitted signal.

[0042] Postamble: The postamble signal, also known as the postamble synchronization code, is used to determine the end position in asynchronous transmission. It is generally located at the end of the transmitted signal.

[0043] Device: An IoT device terminal, or IoT device, is used to modulate and transmit the waveform of energy in acquired environmental or radio frequency signals.

[0044] R2D: Reader to Device link, representing the downlink from a network-side device to an IoT device.

[0045] D2R: Device to Reader link, representing the uplink link from an IoT device to a network-side device.

[0046] PRDCH: Physical Reader to Device Channel, a transmission channel on the R2D link used to transmit downlink information.

[0047] PDRCH: Physical Device to Reader Channel, a transmission channel on a D2R link used to transmit uplink information.

[0048] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0049] like Figure 1 As shown, the system architecture includes: terminal 101 and network-side device 103; wherein, terminal 101 interacts with network-side device 103 through network 102.

[0050] It should be noted that the medium providing the communication link between terminal 101 and network-side device 103 can be a wired network or a wireless network.

[0051] Optionally, the aforementioned wireless or wired networks use standard communication technologies and / or protocols. The network is typically the Internet, but can also be any network, including but not limited to Local Area Networks (LANs), Metropolitan Area Networks (MANs), Wide Area Networks (WANs), mobile, wired or wireless networks, private networks, or any combination of virtual private networks. In some embodiments, technologies and / or formats including Hyper Text Markup Language (HTML), Extensible Markup Language (XML), etc., are used to represent data exchanged over the network. Furthermore, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Networks (VPNs), and Internet Protocol Security (IPSec) can be used to encrypt all or some links. In other embodiments, custom and / or dedicated data communication technologies can be used to replace or supplement the aforementioned data communication technologies.

[0052] Terminal 101 can be referred to as user equipment, terminal equipment, access equipment, user unit, user terminal, or user device, etc.

[0053] In one embodiment, terminal 101 can be a device that provides voice / data to a user, such as a handheld device or in-vehicle device with wireless connectivity. For example, terminal 101 can be a mobile phone, tablet computer, laptop computer, PDA, mobile internet device, virtual reality device, augmented reality device, wireless terminal in industrial control, wireless terminal in autonomous driving, wireless terminal in remote surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, cellular phone, etc. This disclosure does not specifically limit the types of devices that can be used in this embodiment.

[0054] In this embodiment of the disclosure, terminal 101 can also be a device terminal in an IoT system. IoT connects to a network through communication technology, thereby realizing a smart network that enables human-computer interaction and the interconnection of everything. For example, terminal 101 can be understood as an IoT device, or an IoT device terminal. Specifically, it can be understood as an ambient IoT terminal or a passive IoT device terminal. Terminal 101 can also be called UE (User Equipment).

[0055] In some embodiments, network-side device 103 may be a base station, user equipment (UE), repeater, network controlled repeater (NCR), customer premises equipment (CPE), radio frequency signal transmitter, reader, or access point, etc. The base station may be, but is not limited to, a 5G or later version base station (e.g., gNB base station), or a base station in other communication systems (e.g., eNB base station). The base station is responsible for signal transmission and reception, supporting large-area user communication. The UE is a device directly used by the user to send and receive data. An NCR is an active repeater based on the concept of amplification and forwarding, with beamforming and time-division duplex operation capabilities. It is a network controlled repeater used to enhance signal coverage and link quality in wireless communication systems. A repeater is a network device used to enhance signal strength, ensuring that the signal can travel over greater distances. A CPE may include network devices in a home or enterprise, such as routers and switches, used to connect multiple devices to the network. The radio frequency signal transmitter is used for wireless signal transmission, ensuring that the signal can cover a wider area. The reader can be a device used to read RFID tags for data collection and identification. It should be noted that the specific type of the network-side device 103 is not limited in this embodiment.

[0056] Those skilled in the art will know that Figure 1 The number of terminals and network-side devices shown is merely illustrative; any number of terminals, networks, and network-side devices can be included depending on actual needs. This disclosure does not limit the scope of the embodiments.

[0057] In related technologies, the 3GPP organization proposed the concept of Environmental Internet of Things (IoT), which operates without batteries, obtaining energy from the environment or radio frequency signals for waveform modulation and transmission. Due to the expectation of low cost, low power consumption, and low complexity, IoT terminals suffer from limitations in crystal oscillator performance, sampling, and timing capabilities. Furthermore, while New Radio (NR) uses the Physical Downlink Control Channel (PDCCH) to transmit control information, IoT products, aiming for low cost, low power consumption, and low complexity, cannot support the blind detection process of NR's PDCCH. Therefore, new standards are needed to define the transmission process and methods of control information for IoT, enabling network-side devices to schedule IoT devices, allowing IoT devices to acquire transmission resources and command information to complete the transmission process.

[0058] However, the 3GPP organization has not yet reached a definitive conclusion on the design of control information for IoT devices. For example, what content should the control information of IoT devices include, whether the transmission information of IoT devices should be defined separately or utilize existing channels, and the possible format design of commands, etc. How to design a transmission method for control information of IoT devices has become an urgent technical problem to be solved.

[0059] In addition, there may be uplink control information from IoT devices, and the transmission method of the uplink control information also needs to be designed accordingly.

[0060] In order to at least partially solve the above-mentioned technical problems under the above system architecture, this disclosure provides a method for transmitting control information of IoT devices. The method configures or instructs the control information of IoT devices through a higher layer and / or a physical layer. The control information includes D2R control information or R2D control information. The D2R control information or R2D control information includes at least one of higher layer control information and physical layer control information. This method can realize environmental IoT communication, enabling IoT devices to receive control information and perform corresponding operations, thereby achieving low cost, low power consumption, and low complexity.

[0061] This method can be executed by any electronic device with computing capabilities. In some embodiments, the control information transmission method for IoT devices provided in this disclosure can be executed by IoT devices in the above-described system architecture; in other embodiments, the control information transmission method for IoT devices provided in this disclosure can be implemented by network-side devices (such as base stations) in the above-described system architecture.

[0062] Figure 2 This illustration shows a flowchart of a control information transmission method for an Internet of Things (IoT) device according to an embodiment of the present disclosure. In one embodiment, such as Figure 2As shown in the embodiments of this disclosure, the method for transmitting control information of an Internet of Things (IoT) device includes the following steps:

[0063] S202. Configure or instruct control information for IoT devices through higher layers and / or physical layers, wherein the control information includes IoT device-to-network-side device D2R control information or network-side device-to-IoT device R2D control information, and the D2R control information or R2D control information includes at least one of higher layer control information and physical layer control information.

[0064] The control information of IoT devices includes the transmitted resources and the transmitted command information. After obtaining the control information, the IoT device can execute the operation corresponding to the control information, thereby realizing the scheduling of IoT devices by the network side devices.

[0065] In one embodiment, the control information may include D2R control information, which refers to the control information transmitted on the D2R transmission link from the IoT device to the network-side device.

[0066] In one embodiment, the control information may include R2D control information, which refers to the control information transmitted on the R2D transmission link from the network-side device to the IoT device.

[0067] The physical layer is also known as the L1 layer, and correspondingly, physical layer control information refers to L1 layer control information; higher layers refer to L2 and / or L3 layers, and correspondingly, higher layer control information refers to L2 layer control information and / or L3 layer control information.

[0068] It should be noted that the higher layer can also be a layer other than the physical layer, defined according to actual needs. Correspondingly, the higher layer control information can also be the control information configured or indicated by the higher layer.

[0069] In one embodiment, when configuring or instructing control information for an IoT device via a higher-level layer, the configuration or instruction method for the control information includes at least one of the following: configuring or instructing higher-level control information at the Medium Access Control (MAC) layer; configuring or instructing higher-level control information at the target layer; or configuring or instructing higher-level control information at both the MAC layer and the target layer. For example, control information can be configured or instructed via a MAC control element to cause the IoT device to perform the operation corresponding to the control information.

[0070] This disclosure configures or instructs higher-level control information through at least one of the MAC layer and the target layer, thereby enabling the scheduling of IoT devices based on the higher-level control information and improving the reliability of the IoT system.

[0071] In one embodiment, when configuring or indicating control information for an IoT device through the physical layer, the configuration or indication method of the control information includes: indicating or configuring physical layer control information at the physical layer.

[0072] In one embodiment, when configuring or indicating control information for an IoT device through higher and physical layers, the configuration or indication method of the control information includes at least one of the following:

[0073] Higher-level control information is configured or indicated at the MAC layer or target layer, while physical layer control information is indicated at the physical layer; or

[0074] High-level control information is configured or indicated at the high level, and corresponding physical layer control information is transmitted according to the high-level configuration or indication.

[0075] It should be noted that the aforementioned target layer can be a new layer defined in the Internet of Things system, such as configuring or indicating higher-level control information in the L3 layer.

[0076] For example, when higher-layer control information is configured or indicated at the higher layer, and corresponding physical layer control information is transmitted according to the configuration or indication of the higher layer, the higher layer configures or indicates paging-related configurations or indications. The higher-layer control information configured or indicated may include the size of the paging information, the transmission period, etc., and the corresponding physical layer control information transmitted according to the configuration or indication of the higher layer may include the transmission resources corresponding to the paging information, etc.

[0077] For example, when higher-layer control information is configured or indicated at a higher layer, and corresponding physical layer control information is transmitted according to the higher-layer configuration or indication, the higher-layer control information configured or indicated may include information such as enable information, classification information, or format information. For instance, if the higher layer configures or indicates paging enable information, then the physical layer control information indicates information such as paging transmission resources according to the higher layer configuration.

[0078] In this disclosure, control information for IoT devices is configured or instructed through higher-level and / or physical layers. The control information includes D2R control information or R2D control information. The D2R control information or R2D control information includes at least one of higher-level control information and physical layer control information. This enables environmental IoT communication, allowing IoT devices to receive control information and perform corresponding operations, thereby achieving low cost, low power consumption, and low complexity.

[0079] In one embodiment, the method of transmitting control information includes at least one of the following:

[0080] Transmitted in PRDCH or PDRCH;

[0081] Transmitted in a synchronization signal;

[0082] Transmitted in the control channel;

[0083] Transmitted in the reference signal:

[0084] Transmitted in broadcast or paging messages.

[0085] Among them, the synchronization signal is used to synchronize the signal position in asynchronous transmission, and control information can be transmitted in the synchronization signal.

[0086] In one embodiment, control information is transmitted in a synchronization signal, which includes at least one of a preamble synchronization code, an intermediate synchronization code, and a follow-up synchronization code. For example, the control signal can be transmitted in the preamble synchronization code, the intermediate synchronization code, or the follow-up synchronization code, or in any combination of the preamble synchronization code, the intermediate synchronization code, and the follow-up synchronization code.

[0087] The control channel is used to transmit control plane information. The control channel can be divided into broadcast channel, common control channel and dedicated control channel. The control channel transmits control information, which may include R2D control information or D2R control information.

[0088] In one embodiment, the control channel may be a newly defined channel, for example, the control channel may be defined as an R2D control channel or a D2R control channel, or as a PRDCCH or PDRCCH, and this disclosure does not specifically limit it.

[0089] In one embodiment, the control channel can be part of a PRDCH or PDRCH. For example, the control channel can be a specific set of m fields within the PRDCH or PDRCH; or the control channel can be a specific number of n granularities within the PRDCH or PDRCH, such as using the first m granularities of the PRDCH or PDRCH as the control channel. The fields can include the time domain or the frequency domain, etc. It should be noted that m and n can be determined according to actual needs and are not specifically limited.

[0090] A reference signal, also known as a pilot signal, is a known signal provided by the transmitter to the receiver for signal estimation or detection. In this disclosure, control information can be transmitted in the reference signal.

[0091] Broadcast information is a series of control messages that a base station periodically sends to terminals within its coverage area. These messages may include system information blocks, master information blocks, cell-specific reference signals, paging information, and other broadcast information, so that the terminals can access the network and communicate based on the information provided.

[0092] Paging information can be used to establish and maintain communication connections, as well as to transmit signals or information to users. In this disclosure, by transmitting control information through paging information, IoT devices can perform operations corresponding to the control information, thereby realizing the scheduling and communication of the IoT system.

[0093] In addition, higher-layer control information may also be transmitted in the form of non-control information in at least one of the following: PRDCH or PDRCH, synchronization information, reference signals, control channels, broadcast information, or paging information. For example, higher-layer control information may be transmitted in the form of data in PRDCH or PDRCH.

[0094] In this embodiment of the disclosure, by determining the transmission method of control information, the configuration or indication of control information can be realized, the scheduling and communication of the Internet of Things system can be realized, and the system stability and reliability can be improved.

[0095] In one embodiment, when control information is transmitted in the PRDCH, the control information is transmitted at least a portion of the locations within the PRDCH. It should be noted that "at least a portion of the locations within the PRDCH" includes all locations within the PRDCH, as well as a subset of locations within the PRDCH.

[0096] When control information is transmitted in all locations of the PRDCH, for example, it can be transmitted in all fields of the PRDCH. The content of the transmitted control information may include command messages, paging messages, and other information.

[0097] When control information is transmitted in a portion of the PRDCH, the content of the transmitted control information may include command messages, paging messages, and other similar information. For example, it may be transmitted in a subset of fields within the PRDCH. This subset of fields may be a single field (such as a control information field) or multiple fields, but not exceeding X, where X is the total number of fields in the PRDCH.

[0098] For example, physical layer control information is transmitted in one part of the domains of the PRDCH, while higher layer control information can be transmitted in other domains of the PRDCH, which are domains in the PRDCH other than the aforementioned part of the domains.

[0099] For example, physical layer control information is transmitted in a portion of the domains of the PRDCH, while higher layer control information is transmitted in all domains of the PRDCH.

[0100] For example, physical layer control information or higher layer control information may be transmitted in one part of the domains of the PRDCH, but not in other domains of the PRDCH.

[0101] It should be noted that the field of PRDCH used to transmit control information can be determined according to actual needs, and this disclosure does not impose specific limitations on it.

[0102] In one embodiment, when control information is transmitted in the PDRCH, the control information is transmitted at least a portion of the locations within the PDRCH. It should be noted that "at least a portion of the locations within the PDRCH" can include all locations within the PDRCH, or it can include only a subset of locations within the PDRCH.

[0103] When control information is transmitted in all locations of the PDRCH, for example, it can be transmitted in all fields of the PDRCH. The content of the transmitted control information may include command messages, paging messages, and other information.

[0104] When control information is transmitted in a portion of the PDRCH, the content of the transmitted control information may include command messages, paging messages, and other similar information. For example, it may be transmitted in a subset of fields within the PDRCH. This subset of fields may be a single field (such as the control information field) or multiple fields, but not exceeding X, where X is the total number of fields in the PDRCH.

[0105] For example, physical layer control information is transmitted in one part of the domains of the PDRCH, while the remaining information can be transmitted in other domains of the PDRCH. For example, the remaining information is data information, and other domains refer to the domains in the PDRCH other than the aforementioned part of the domains.

[0106] For example, physical layer control information is transmitted in one part of the domains of the PDRCH, while the remaining information can be transmitted in all domains of the PDRCH, such as data information.

[0107] In this embodiment of the disclosure, by determining the position of control information in PDRCH or PRDCH, the configuration or indication of control information can be made more stable, thereby improving the effectiveness of IoT system scheduling.

[0108] In one embodiment, when control information is transmitted in the control channel, it includes at least one of the following: both higher-layer control information and physical layer control information are transmitted in the control channel; higher-layer control information is transmitted in the non-control channel of the PRDCH, and physical layer control information is transmitted in the control channel; higher-layer control information is transmitted in the PRDCH, and physical layer control information is transmitted in the control channel.

[0109] It should be noted that physical layer control information is transmitted only in a specially designated control channel. The transmission method of higher layer control information is not specifically limited. It can be transmitted in the control channel along with physical layer control information, or in a non-control channel in PRDCH or in PRDCH, thereby ensuring the effectiveness of IoT system scheduling.

[0110] In one embodiment, the transmission format for transmitting control information such as PRDCH, PDRCH, synchronization signals, control channels, reference signals, broadcast information, or paging information includes: X fields, where the i-th field includes Y... i The granularity is Z, and the size of the control information is Z granularities.

[0111] Where X, Yi, and Z are natural numbers, i = {0, ..., X-1}, and the granularity includes at least one of the following: bit, transport block, covered Orthogonal Frequency Division Multiplexing (OFDM) symbol, Non-Return-to-Zero (OOK) chip, OFDM time slot, microsecond, sampling point, PRDCH chip, PRDCH symbol, PRDCH time slot, PRDCH sampling point, PDRCH chip, PDRCH symbol, PDRCH time slot, PDRCH sampling point, R2D chip, R2D symbol, R2D time slot, R2D sampling point, D2R chip, D2R symbol, D2R time slot, and D2R sampling point.

[0112] It should be noted that the domain of transmission control information can be at least a portion of frequency resources within a certain time region. For example, PDRCH includes X domains, namely domain 0, domain 1, ..., domain X-1, where domain 0 includes Y granularities, domain 1 includes Y1 granularities, and domain X-1 includes Y... X-1 The total size of the control information is Z granularities, where...

[0113] It should be noted that at least some of the X fields in PDRCH may or may not exist. Y0, Y1, ..., Y X-1 The values ​​can be the same or different, depending on the actual situation, and this disclosure does not make any specific restrictions.

[0114] Granularity is a basic unit of time. Granularity can include only one of the above basic units, or it can include multiple of the above basic units.

[0115] When the granularity includes multiple basic units, the granularity can be the same basic unit, for example, the granularity includes two chips; the granularity can also be different basic units, for example, the granularity includes a combination of a chip and an OFDM symbol. For example, a granularity can be defined as the sum of the durations of a low-level chip and a high-level chip.

[0116] In this context, "Slot" can also be referred to as a time unit, such as the OFDM slot, PRDCH slot, PDRCH slot, R2D slot, and D2R slot mentioned above. In the NR system, there are five selectable subcarrier spacings. Correspondingly, the number of slots in each subframe depends on the parameter μ, which has five values ​​from 0 to 4. When μ = 0, there is 1 slot or subframe, and each slot has a duration of 1 ms; when μ = 1, there are 2 slots or subframes, and each slot has a duration of 0.5 ms; when μ = 2, there are 4 slots or subframes, and each slot has a duration of 0.25 ms; when μ = 3, there are 8 slots or subframes, and each slot has a duration of 0.125 ms; when μ = 4, there are 16 slots or subframes, and each slot has a duration of 0.0625 ms.

[0117] OFDM symbols, also known as Symbols, are short for time-domain symbols. Time-domain symbols can also be combined with other multiple access methods for naming. The length of time-domain symbols can vary depending on the subcarrier spacing. Examples include OFDM symbols, R2D symbols, and D2R symbols mentioned above. Typically, each slot includes 14 symbols.

[0118] A sampling point is a series of discrete sampling points obtained from transmitted or received waveforms by nodes such as base stations or IoT devices at certain time intervals. It is the smallest unit of processing at the transmitting or receiving end. Sampling points can be classified according to their purpose, such as PRDCH sampling points, PDRCH sampling points, R2D sampling points, and D2R sampling points.

[0119] Chips are used to represent the temporal resolution of a signal, and the chip rate is the number of chips transmitted per second, which determines the highest signal rate that the system can process. Chips can be classified according to their purpose, such as PRDCH chips, PDRCH chips, R2D chips, D2R chips, and OOK chips.

[0120] The definition of a microsecond (μs) can reuse existing international standard definitions. The time granularity of a microsecond is mainly used to characterize a specific time granularity, defined as AAμs, where AA is a specific numerical value. For example, the time granularity of PDRCH is defined as 44.4 μs.

[0121] A bit is a unit of measurement for the amount of information in control information, and its definition can be reused from existing international standards.

[0122] Transport blocks are the payloads transmitted between higher layers and the physical layer. Transport blocks can consist of millions of bits and can reuse existing international standard definitions.

[0123] In one embodiment, all X fields exist, and the X fields are predefined.

[0124] In another embodiment, the existence of at least some of the X domains is configured or indicated by the higher layer or the target domain. If a domain does not exist, it is reserved in the form of a reserve bit, or the non-existent domain as a whole is not reserved.

[0125] Whether a certain domain among X domains exists can be determined by higher-level configuration or indication. For example, whether domain P exists depends on whether domain P is enabled in the control information configured or indicated by the higher-level configuration. If domain P is enabled in the control information configured or indicated by the higher-level configuration, then domain P exists; if domain P is not enabled, then domain P does not exist.

[0126] The existence of a subset of X domains can be configured or indicated by the target domain. For example, the existence of domain P depends on whether the target domain's control information indicates whether domain P exists. Here, the target domain refers to all the other X domains besides the subset of domains.

[0127] Correspondingly, the method for determining whether all of the X fields exist is the same as the method for determining whether some fields exist, and will not be repeated here.

[0128] In one embodiment, when some of the X fields are missing, those fields are reserved in the form of reserve bits. For example, if field P is configured or indicated to be non-existent, and the size of field P is Xp, then although field P is non-existent, Xp granularities are still set at the corresponding positions of field P, that is, reserve granularities. These Xp granularities do not contain any information and are only reserved granularities, which can also be called R granularities.

[0129] In another embodiment, when some of the X domains are missing, those missing domains will not be retained as a whole. For example, if domain P is configured or indicated to be non-existent, and the size of domain P is Xp granularities, then domain P will not be retained; configuring Xp to 0 means that the size of domain P is 0 granularities.

[0130] Correspondingly, the granularity retention method for all X fields not existing is the same as the granularity retention method when some fields are not existing, and will not be repeated here.

[0131] In one embodiment, the control information includes at least one transmission format.

[0132] When the control information includes a transmission format, the R2D control information and the D2R control information can be set to the same transmission format.

[0133] When control information includes two transmission formats, different transmission formats can be set for R2D control information and D2R control information respectively. For example, one transmission format can correspond to R2D control information, and the other transmission format can correspond to D2R control information.

[0134] When control information includes multiple transmission formats, one or more transmission formats can be set for R2D control information or D2R control information respectively. For example, two transmission formats can be set for R2D control information, represented by Format0 and Format 1 respectively.

[0135] It should be noted that the specific number of transmission formats and the different transmission formats can be determined according to actual needs, and this disclosure does not impose specific limitations on this.

[0136] In this embodiment of the disclosure, by setting the transmission format of control information, the consistency of control information transmission can be ensured, thereby guaranteeing the scheduling and communication of the Internet of Things system.

[0137] In one embodiment, when the control information includes multiple transmission formats, the control information is length aligned to obtain the processed control information.

[0138] The length alignment process described above can truncate longer control information based on the shorter control information length, so that the length of the truncated longer control information is consistent with the length of the shorter control information. For example, if the control information includes multiple transmission formats, the shortest control information length is used as the target length, and the control information other than the shortest control information is truncated. The truncated length of the control information is the difference between the current length of the control information and the target length.

[0139] The length alignment process described above can also be based on the length of the longer control information as a standard, padding the shorter control information to make the length of the shorter control information consistent with the length of the longer control information. For example, if the control information includes multiple formats, the longest control information length is used as the target length, and the control information other than the longest control information is padded, with the padded length being the difference between the target length and the current length of the control information.

[0140] In one embodiment, alignment can also be performed according to the length of the R2D control information or the D2R control information, respectively.

[0141] In one embodiment, when the control information includes multiple transmission formats, the control information is length aligned to obtain the processed control information, including: aligning the lengths of the control information in multiple transmission formats to a preset number of length values, wherein the preset number is less than the number of transmission formats in the control information, and the preset number is a positive integer; wherein the preset number of length values ​​is predefined, or configured or indicated by a higher layer.

[0142] For example, the lengths of control information from multiple transmission formats can be aligned to one of the length values, or the lengths of control information from multiple transmission formats can be aligned to several of the length values. The preset quantity can be predefined, configured by a higher level, or indicated. The preset quantity can be determined according to actual needs.

[0143] In this embodiment of the disclosure, by performing length alignment processing on control information of various transmission formats, the consistency of control information transmission can be guaranteed and the transmission complexity of control information can be reduced.

[0144] Figure 3 This diagram illustrates a flowchart of another method for transmitting control information in an Internet of Things (IoT) device, as provided in an embodiment of this disclosure. Figure 3 As shown, in one embodiment, the method further includes:

[0145] S302. Higher layers or the physical layer configure or instruct control information based on the information reported by the IoT device. The above-mentioned reporting by the IoT device constitutes a D2R transmission.

[0146] The higher or physical layer can configure or instruct the relevant control information for accessing time-domain or frequency-domain resources of IoT devices.

[0147] In one embodiment, the reported information includes at least one of the following: capability information; auxiliary information; D2R control information; specific D2R transmission information.

[0148] Capability information is used to characterize the communication capabilities of IoT devices. When reporting capability information, IoT devices can report information such as their type and supported duty cycle.

[0149] When the reported information is supplementary, IoT devices can report information related to their duty cycle synchronization. For example, when entering deep or light sleep mode, they can inform the reader of the IoT device's listening time and interval.

[0150] When the reported information is D2R control information, the IoT device can report the ACK / NACK feedback of the previous R2D control information. The higher layer can then configure or instruct whether to retransmit based on the ACK / NACK information.

[0151] When the reported information is specific D2R control information, for example, configuration or instructions can be made for MSG1 / MSG3 information reported by IoT devices. For MSG1 information, it can be decided to provide ACK, NACK, or no feedback; for MSG3 information, it can be decided to provide MSG4 or no feedback. MSG4 may involve a contention resolution mechanism, such as providing a correct EPC to inform the IoT device with the corresponding EPC that it has successfully competed for the contention.

[0152] It should be noted that the specific implementation methods of the information content, configuration or indication form, transmission method, transmission format, etc. of the above-mentioned high-level and / or physical layer configuration or indication control information are merely examples provided to illustrate the embodiments of this disclosure, and should not be regarded as a limitation on the protection scope of this disclosure. Other combinations and transformations of the information content, configuration or indication form, transmission method, and transmission format of the control information may also be included within the protection scope of this disclosure according to actual needs, and this disclosure does not make specific limitations.

[0153] To deepen the understanding of the control information transmission method of the IoT devices disclosed herein, the following is in conjunction with the appendix. Figures 4 to 17 Please provide a detailed explanation.

[0154] like Figure 4 As shown, when control information is transmitted in the PRDCH, it can be located in the first part of the PRDCH. The first part of the PRDCH is considered to be a newly defined control information channel, dedicated to transmitting control information. For example, the PRDCH has a total of 22 bits, of which the first 8 bits are considered to be the control information channel, dedicated to transmitting control information.

[0155] like Figure 5 As shown, control information is transmitted in the PRDCH, located in the first part of the PRDCH, but no definition is made for the first part; only the first part of the PRDCH is considered usable for transmitting control information. For example, the PRDCH has a total of 22 bits, of which the first 8 bits are considered usable for transmitting control information.

[0156] like Figure 6 As shown, control information is transmitted in a newly defined control channel, which is located at the beginning of the PRDCH. This means the control information will be transmitted in a dedicated control channel, which is a newly defined channel preceding the PRDCH. For example, the control channel is defined as the PRDCCH channel, which has 8 bits and is considered suitable for transmitting control information.

[0157] like Figure 7As shown, control information is divided into physical layer control information and higher layer control information. Both physical layer control information and higher layer control information are transmitted in the PRDCH, but they are transmitted separately. For example, a portion of the PRDCH channel is defined for transmitting physical layer control information, while the remaining fields are used for transmitting higher layer control information.

[0158] like Figure 8 As shown, control information is divided into physical layer control information and higher layer control information. Both physical layer control information and higher layer control information are transmitted in the PRDCH, but only a portion of the PRDCH is transmitted. For example, a portion of the PRDCH channel is defined for transmitting physical layer control information and / or higher layer control information, while other portions are used to transmit other information besides control information.

[0159] like Figure 9 As shown, control information is divided into physical layer control information and higher-layer control information. Both physical layer control information and higher-layer control information are transmitted in the PRDCH. However, physical layer control information is transmitted only in a portion of the PRDCH, while higher-layer control information can be transmitted in all portions of the PRDCH. For example, a portion of the PRDCH channel is defined for transmitting physical layer control information, while higher-layer control information is not restricted and can be transmitted in any portion of the PRDCH.

[0160] like Figure 10 As shown, control information is divided into physical layer control information and higher layer control information. Physical layer control information and higher layer control information are transmitted separately. Physical layer control information is transmitted in a dedicated control channel, while control information is transmitted in a newly defined channel, such as the PRDCCH channel. Higher layer control information is transmitted in the PRDCH.

[0161] like Figure 11 As shown, control information is divided into physical layer control information and higher-layer control information. Physical layer control information is transmitted in a dedicated control channel, which is a newly defined channel, such as the PRDCCH channel. Higher-layer control information can be transmitted either in this newly defined control channel PRDCCH or in the PRDCH channel.

[0162] like Figure 12 As shown, control information is divided into physical layer control information and higher layer control information. Physical layer control information or higher layer control information can only be transmitted in dedicated control channels, which are newly defined channels, such as the PRDCCH channel. The PRDCH channel, however, cannot transmit control information.

[0163] like Figure 13As shown, control information is transmitted in the PRDCH, which consists of multiple fields. The PRDCH that transmits control information is one of these fields, as shown below. Figure 13 Domain 0 in the control information field can be named the control information field. Control information can only be transmitted in the control information field. The control information may include physical layer control information or higher layer control information.

[0164] like Figure 14 As shown, control information is transmitted in the PRDCH, which consists of multiple AND fields. The PRDCH for transmitting control information comprises multiple fields, such as... Figure 14 Domains 0, 1, and 2 in the control information domain can be named control information domains. Control information can only be transmitted in control information domains and can include physical layer control information or higher layer control information.

[0165] like Figure 15 As shown, control information is transmitted in the control channel, which, or PRDCH, consists of multiple fields. For example... Figure 15 In the PRDCH, the control channel includes domains 0 to 2, and the control information can be transmitted in all domains 0 to X-1, totaling X domains. These domains 0 to X-1 can be named the control information domains. Control information can only be transmitted in the control information domains. The control information can include physical layer control information or higher layer control information.

[0166] like Figure 16 As shown, the channel for transmitting control information can have multiple domains, and some of these domains may be configured or indicated for enabling by higher layers or other domains. For example, multiple domains may be... Figure 16 In the control information, domains 0 through X-1 are configured or indicated to be disabled by higher layers or other domains (domains 0 through X-1 other than domain 2). Domain 2 no longer performs its corresponding function, but the granularity occupied by domain 2 remains unchanged to ensure that the format or size of the control information does not change. When domain 2 is disabled, it continues to occupy space using a reserve granularity; these reserve granularities can be written as R bits.

[0167] like Figure 17 As shown, the channel for transmitting control information can have multiple domains, and some of these domains may be configured or indicated for enabling by higher layers or other domains. For example, multiple domains may be... Figure 17 In the domains 0 to X-1, domain 2 is configured or indicated to be disabled by higher layers or other domains (domains 0 to X-1 other than domain 2). During transmission, domain 2 is directly deleted and occupies 0 granularity.

[0168] It should be noted that the transmission method of control information in other channels or other information is similar to that in PRDCH, and the similarities will not be elaborated further.

[0169] Based on the same inventive concept, this disclosure also provides a control information transmission device for an Internet of Things (IoT) device, as described in the following embodiments.

[0185] It should be noted that the control information includes at least one transmission format.

[0186] In one embodiment, the device further includes an alignment module (not shown in the figures), which is used to perform length alignment processing on the control information when the control information includes multiple transmission formats, to obtain processed control information.
