[0047] The specific implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0048] As shown in FIG. 1, the system architecture includes a terminal 101 and a network side device 103; wherein the terminal 101 interacts with the network side device 103 through a network 102.

[0049] It should be noted that the medium providing the communication link between the terminal 101 and the network side device 103 can be a wired network or a wireless network.

[0050] The wireless network or wired network described above uses standard communication techniques and / or protocols. The network is usually the Internet, but can also be any network, including but not limited to a local area network (Local Area Network, LAN), a metropolitan area network (Metropolitan Area Network, MAN), a wide area network (Wide Area Network, WAN), a mobile, wired or wireless network, a private network or any combination of virtual private networks). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (Hyper Text Mark-up Language, HTML), Extensible Markup Language (Extensible Markup Language, XML), etc. are used to represent the data exchanged through the network. In addition, all or some links can be encrypted using conventional encryption technologies such as Secure Socket Layer (Secure Socket Layer, SSL), Transport Layer Security (Transport Layer Security, TLS), Virtual Private Network (Virtual Private Network, VPN), Internet Protocol Security (Internet Protocol Security, IPSec), etc. In other embodiments, custom and / or dedicated data communication technologies can be used instead of or in addition to the above data communication technologies.

[0051] The terminal 101 can be referred to as a user equipment, terminal device, access device, subscriber unit, subscriber terminal, or user apparatus, etc.

[0052] In an embodiment, the terminal 101 can be a device that provides voice / data to a user, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. For example, the terminal 101 can be a cell phone, a tablet computer, a notebook computer, a palm computer, a mobile Internet device, a virtual reality device, an augmented reality device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a cellular phone, etc., and the present disclosure is not limited thereto.

[0053] In an embodiment of the present disclosure, the terminal 101 can also be a device terminal in an IoT system. IoT can be connected to a network through communication technology, so as to realize man-machine interaction and smart network of all things connected. For example, the 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. The terminal 101 can also be referred to as a UE (User Equipment).

[0054] In some embodiments, the network-side device 103 can be a base station, a user equipment (UE), a repeater, a network controlled repeater (NCR), a customer premises equipment (CPE), a radio frequency signal transmitter, a reader, or an access point, etc. The base station can be, but is not limited to, a 5G and later version base station (e.g., a gNB base station), or a base station in other communication systems (e.g., an eNB base station), which is responsible for the transmission and reception of signals and supports a large area of user communication. The UE is a device directly used by a user to send and receive data. The NCR is an active repeater based on the amplification and forwarding concept, has the ability of beamforming and time division duplex operation, and is a network-controlled repeater used to enhance signal coverage and link quality in a wireless communication system. The repeater is a network device used to enhance signal strength and ensure that signals can cross a longer distance. The CPE can include network devices in homes or enterprises, such as routers, switches, etc., for connecting multiple devices to a network. The radio frequency signal transmitter is used for the transmission of wireless signals to ensure that signals can cover a wider area. The reader can be a device used to read radio frequency identification tags for data collection and identification. It should be noted that the specific type of the network-side device 103 is not limited in the embodiments of the present disclosure.

[0055] Those skilled in the art can know that the number of terminals and network-side devices in FIG. 1 is only illustrative, and any number of terminals, networks, and network-side devices can be provided according to actual needs. The embodiments of the present disclosure do not limit this.

[0056] In the related art, the 3GPP organization proposes the concept of environmental Internet of Things, which does not need to rely on a battery, but obtains energy in the environment or radio frequency signals to perform waveform modulation and transmission. Since it is expected that the product can be low-cost, low-power, and low-complexity, limited by cost, the IoT terminal has poor crystal oscillator difference, sampling, and timing functions. At the same time, the new radio (NR) uses a physical downlink control channel (PDCCH) to transmit control information, but the IoT product expects to be low-cost, low-power, and low-complexity, and cannot support the blind detection process of the PDCCH of the NR. A new standard needs to be developed for IoT to define the transmission process and transmission method of control information, etc., so as to realize the scheduling of the network-side device to the Internet of Things device, so that the Internet of Things device obtains the transmission resource and the transmission command information, and completes the transmission process.

[0057] However, the 3GPP organization has not yet reached a conclusion on the design of control information of the Internet of Things device, for example, what content needs to be included in the control information of the Internet of Things device, whether the transmission information of the Internet of Things device is separately defined or multiplexed with the existing channel, and the possible format design of the command. How to design a transmission mode of control information of the Internet of Things device becomes a technical problem to be solved.

[0058] In addition, there can be uplink control information of the Internet of Things device, and the transmission mode of the uplink control information also needs to be designed correspondingly.

[0085] In one embodiment, the control information is transmitted in a synchronization signal, and the synchronization signal includes at least one of a preamble synchronization code, an intermediate synchronization code, and a postamble synchronization code. For example, the control signal can be transmitted in the preamble synchronization code, the intermediate synchronization code, or the postamble synchronization code, or any combination of the above.

[0086] The control channel is used to transmit control plane information, and the control channel can be divided into a broadcast channel, a common control channel and a dedicated control channel. The control channel transmits control information, and the control information can include R2D control information or D2R control information.

[0087] In an embodiment, the control channel can be a newly defined channel, for example, the control channel is defined as an R2D control channel or a D2R control channel, or is defined as a PRDCCH or a PDRCCH, and the disclosure does not make specific limitations.

[0088] In an embodiment, the control channel can be part of the PRDCH or the PDRCH, for example, the control channel is a specific m domain in the PRDCH or the PDRCH; or the control channel is a specific number n of granularities in the PRDCH or the PDRCH, such as the first m granularities in the PRDCH or the PDRCH as the control channel.

[0097] For example, the physical layer control information is transmitted in part of the fields in the PRDCH, and the high layer control information is transmitted in all the fields in the PRDCH, which are the fields in the PRDCH other than the part of the fields.

[0098] For example, the physical layer control information is transmitted in part of the fields in the PRDCH, and the high layer control information is transmitted in all the fields in the PRDCH.

[0099] For example, the physical layer control information or the high layer control information is transmitted in part of the fields in the PRDCH, and cannot be transmitted in other fields in the PRDCH.

[0104] For example, the physical layer control information is transmitted in a part of the PDRCH, and the remaining information can be transmitted in other fields of the PDRCH, e.g., the remaining information is data information, and the other fields refer to the fields in the PDRCH other than the part of the fields mentioned above.

[0105] For example, the physical layer control information is transmitted in a part of the PDRCH, and the remaining information can be transmitted in all fields of the PDRCH, e.g., the remaining information is data information.

[0106] In the embodiments of the present disclosure, by determining the position of the control information in the PDRCH or the PRDCH, the configuration or indication of the control information can be more stable, and the effectiveness of the scheduling of the Internet of Things system can be improved.

[0114] 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 one chip and one OFDM symbol. For example, a granularity is defined as the sum of the duration of one low-level chip and one high-level chip.

[0115] Wherein, for Slot, also called time unit, such as OFDM time slot, PRDCH time slot, PDRCH time slot, R2D time slot, D2R time slot, etc. In the NR system, there are 5 optional subcarrier spacings, and correspondingly, the time slot in each subframe depends on the parameter μ, which has 5 values, 0-4, when μ=0, the number of time slots or subframes is 1, and the time length of each time slot is 1ms; when μ=1, the number of time slots or subframes is 2, and the time length of each time slot is 0.5ms; when μ=2, the number of time slots or subframes is 4, and the time length of each time slot is 0.25ms; when μ=3, the number of time slots or subframes is 8, and the time length of each time slot is 0.125ms; when μ=4, the number of time slots or subframes is 16, and the time length of each time slot is 0.0625ms.

[0116] OFDM symbol, also referred to as Symbol, is short for time domain symbol, time domain symbol can also be named in combination with other multiple access modes, and the length of time domain symbol can be different for different subcarrier spacings. For example, OFDM symbol, R2D symbol, D2R symbol, etc. described above. Generally, each slot includes 14 symbols.

[0117] Sampling points are a series of discrete sampling points obtained by a node such as a base station or an Internet of Things device from a transmitted or received waveform according to a certain time interval, and are the smallest unit of processing at the transmitting or receiving end. PRDCH sampling points, PDRCH sampling points, R2D sampling points, D2R sampling points, etc. can be divided according to the purpose of sampling points.

[0118] Chips are used to represent the time resolution of a signal, and the chip rate is the number of chips transmitted per second, which determines the highest rate at which the system can process signals. PRDCH chips, PDRCH chips, R2D chips, D2R chips, OOK chips, etc. can be divided according to the purpose of chips.

[0119] The definition of microsecond μs can reuse the existing international standard definition, and the time granularity of microsecond is mainly used to represent that a certain time granularity is defined as AA μs, and AA is a specific value. For example, the time granularity of PDRCH is defined as 44.4 μs.

[0120] Bits are a unit of measurement of the amount of control information, and can reuse the existing international standard definition.

[0121] A transport block is a payload transferred between a high layer and a physical layer, and a transport block can be composed of millions of bits. The existing international standard definition can be reused.

[0122] In one embodiment, X domains exist, and the X domains are predefined.

[0123] In another embodiment, whether at least part of the X domains exists is configured or indicated by a high layer or a target domain. If the domain does not exist, the whole domain that is reserved or does not exist in the form of a reserved bit is not reserved.

[0124] Whether part of the X domains exists can be configured or indicated by a high layer. For example, whether domain P exists depends on whether domain P is enabled in the control information configured or indicated by the high layer. If domain P is enabled in the control information configured or indicated by the high layer, domain P exists. If domain P is not enabled, it is determined that domain P does not exist.

[0125] Whether the part of the X domains exists or not can be configured or indicated by the target domain, for example, whether the domain P exists or not depends on whether the domain P is indicated in the control information of the target domain. Wherein, the target domain is the other domain in the X domains except the part of the domain.

[0126] Correspondingly, the determination manner of whether all the X domains exist or not is the same as the determination manner of whether the part of the domain exists or not, which will not be repeated here.

[0127] In one embodiment, when the part of the X domains does not exist, the part of the domain will be reserved in the form of reserve bit. For example, if the domain P is configured or indicated as not existing, the size of the domain P is Xp, then the domain P although does not exist, but Xp granules are still set in the position corresponding to the domain P, that is, reserve granules, and the Xp granules do not contain any information, which are only reserved granules, also can be called R granules.

[0128] In another embodiment, when the part of the X domains does not exist, the part of the domain will not be reserved as a whole. For example, if the domain P is configured or indicated as not existing, the size of the domain P is Xp granules, then the domain P will not be reserved, and Xp is configured as 0, that is, the size of the domain P is 0 granules.

[0129] Correspondingly, the granule reservation manner of all the X domains not existing is the same as the granule reservation manner of the part of the domain not existing, which will not be repeated here.

[0130] In one embodiment, the control information includes at least one transmission format.

[0131] When the control information includes one transmission format, the R2D control information and the D2R control information can be set with the same transmission format.

[0132] When the control information includes two transmission formats, the R2D control information and the D2R control information can be set with different transmission formats respectively. For example, one transmission format corresponds to the R2D control information, and the other transmission format corresponds to the D2R control information.

[0133] When the control information includes multiple transmission formats, one or more transmission formats can be set for the R2D control information or the D2R control information, for example, two transmission formats are set for the R2D control information, which are represented by Format 0 and Format 1 respectively.

[0134] It should be noted that the specific number of transmission formats and different transmission formats can be determined according to actual needs, which are not limited in the present disclosure.

[0135] In the embodiments of the present disclosure, by setting the transmission format of the control information, the consistency of the control information transmission can be ensured, and the scheduling and communication of the Internet of Things system can be guaranteed.

[0136] In one embodiment, when the control information includes multiple transmission formats, the length alignment processing is performed on the control information to obtain processed control information.

[0137] The length alignment processing can be performed based on the shorter control information length as the standard to cut the longer control information, so that the length of the cut longer control information is consistent with the length of the shorter control information. For example, if the control information includes multiple transmission formats, the length of the shortest control information is taken as the target length, and the control information other than the shortest control information is cut, and the cut length of the control information is the difference between the current length of the control information and the target length.

[0138] The length alignment processing can also be performed based on the longer control information length as the standard to pad the shorter control information, so that the length of the padded shorter control information is consistent with the length of the longer control information. For example, if the control information includes multiple formats, the length of the longest control information is taken as the target length, and the control information other than the longest control information is padded, and the padding length of the control information is the difference between the target length and the current length of the control information.

[0139] In one embodiment, the length alignment can also be performed according to the length of the R2D control information or the D2R control information respectively.

[0140] In one embodiment, when the control information includes multiple transmission formats, the length alignment processing is performed on the control information to obtain processed control information, including: aligning the lengths of the control information of the multiple transmission formats to a preset number of length values, the preset number being less than the number of types of transmission formats in the control information, and the preset number being a positive integer; wherein the preset number of length values are predefined or configured or indicated by a higher layer.

[0141] For example, the lengths of the control information of the multiple transmission formats can be aligned to one length value, or the lengths of the control information of the multiple transmission formats can be aligned to several length values. The preset number can be predefined, or configured or indicated by a higher layer, and the preset number can be determined according to actual needs.

[0142] In the embodiments of the present disclosure, by performing the length alignment processing on the control information of the multiple transmission formats, the consistency of the control information transmission can be ensured, and the transmission complexity of the control information can be reduced.

[0143] FIG. 3 shows a flowchart of another control information transmission method of an Internet of Things device provided by an embodiment of the present disclosure. As shown in FIG. 3, in one embodiment, the method further includes:

[0144] S302, a high layer or a physical layer configures or indicates control information according to information reported by the Internet of Things device. The information reported by the Internet of Things device is for one-time D2R transmission.

[0145] The high layer or the physical layer can configure or indicate related control information of access time domain resources or frequency domain resources of the Internet of Things device.

[0146] In one embodiment, the reported information includes at least one of the following: capability information; auxiliary information; D2R control information; and specific D2R transmission information.

[0147] The capability information is used to represent what kind of communication capability the Internet of Things device has. When the reported information is the capability information, the Internet of Things device can report category information of the Internet of Things device, capability information supporting duty cycle, and the like.

[0148] When the reported information is the auxiliary information, the Internet of Things device can report information related to duty cycle synchronization of the Internet of Things device. For example, when deep sleep or light sleep is performed, the listening time and listening interval of the Internet of Things device are informed to the reader.

[0149] When the reported information is the D2R control information, the Internet of Things device can report ACK / NACK feedback to the previous R2D control information, and the high layer configures or indicates whether to perform retransmission according to the ACK / NACK information.

[0150] When the reported information is the specific D2R control information, for example, MSG1 / MSG3 information reported by the Internet of Things device can be configured or indicated, ACK or NACK can be fed back or not fed back for the MSG1 information, and MSG4 or not fed back can be fed back for the MSG3 information. The MSG4 can involve a contention resolution mechanism, for example, a correct EPC is fed back to inform the Internet of Things device corresponding to the EPC that the contention is successful.

[0151] It should be noted that the specific implementation manners of the information content, the configuration or indication form, the transmission manner, and the transmission format of the control information configured or indicated by the high layer and / or the physical layer are only examples provided for describing the embodiments of the present disclosure, and should not be regarded as a limitation on the protection scope of the present disclosure. Other combination manners and transformation forms of the information content, the configuration or indication form, the transmission manner, and the transmission format of the control information are also within the protection scope of the present disclosure, and the present disclosure is not specifically limited.

[0152] In order to deepen the understanding of the control information transmission manner of the Internet of Things device of the present disclosure, the following will be described in detail in combination with FIGS. 4-17.

[0153] As shown in FIG. 4, when the control information is transmitted in the PRDCH, it can be located in the front portion of the PRDCH, which is considered to be a newly defined control information channel, dedicated for transmitting the control information. For example, the PRDCH has a total of 22 bits, of which the front 8 bits are considered to be a control information channel, dedicated for transmitting the control information.

[0154] As shown in FIG. 5, when the control information is transmitted in the PRDCH, it can be located in the front portion of the PRDCH, but no definition is made, and only the front portion of the PRDCH is considered to be able to transmit the control information. For example, the PRDCH has a total of 22 bits, of which the front 8 bits are considered to be able to transmit the control information.

[0155] As shown in FIG. 6, the control information is transmitted in a newly defined control channel, which is located at the head of the PRDCH, i.e., the control information will be transmitted in a dedicated control channel, which is a newly defined channel, located before the PRDCH. For example, the control channel is defined as a PRDCCH channel, which has a total of 8 bits, and is considered to be able to transmit the control information.

[0156] As shown in FIG. 7, the control information is divided into physical layer control information and high layer control information, both of which are transmitted in the PRDCH, but the physical layer control information and the high layer control information are transmitted separately. For example, a part of the domain in the PRDCH channel is defined for transmitting the physical layer control information, and the other domains, except the part of the domain in the PRDCH channel, are used for transmitting the high layer control information.

[0157] As shown in FIG. 8, the control information is divided into physical layer control information and high layer control information, both of which are transmitted in the PRDCH, and the physical layer control information and the high layer control information are transmitted only in a part of the PRDCH. For example, a part of the domain in the PRDCH channel is defined for transmitting the physical layer control information and / or the high layer control information, and the other domains are used for transmitting other information, except the control information.

[0158] As shown in FIG. 9, the control information is divided into physical layer control information and high layer control information, both of which are transmitted in the PRDCH, the physical layer control information is transmitted only in a part of the PRDCH, and the high layer control information can be transmitted in all parts of the PRDCH. For example, a part of the domain in the PRDCH channel is defined for transmitting the physical layer control information, and the high layer control information is not limited thereto, and can be transmitted in any domain of the PRDCH.

[0159] As shown in Fig. 10, the control information is divided into physical layer control information and high layer control information, the physical layer control information and the high layer control information are transmitted separately, the physical layer control information is transmitted in a special control channel, the control channel is a newly defined channel, for example, PRDCCH channel, and the high layer control information is transmitted in PRDCH.

[0160] As shown in Fig. 11, the control information is divided into physical layer control information and high layer control information, the physical layer control information is transmitted in a special control channel, the control channel is a newly defined channel, for example, PRDCCH channel, and the high layer control information can be transmitted in the newly defined control channel PRDCCH or in PRDCH.

[0161] As shown in Fig. 12, the control information is divided into physical layer control information and high layer control information, the physical layer control information or the high layer control information can be transmitted only in a special control channel, the control channel is a newly defined channel, for example, PRDCCH channel, and PRDCH cannot transmit the control information.

[0162] As shown in Fig. 13, the control information is transmitted in PRDCH, the PRDCH is composed of multiple domains. The PRDCH transmitting the control information is one of the domains, for example, domain 0 in Fig. 13, which can be named as control information domain, the control information can be transmitted only in the control information domain, and the control information can include physical layer control information or high layer control information.

[0163] As shown in Fig. 14, the control information is transmitted in PRDCH, the PRDCH is composed of multiple domains. The PRDCH transmitting the control information is multiple domains, for example, domain 0, domain 1 and domain 2 in Fig. 14, which can be named as control information domain, the control information can be transmitted only in the control information domain, and the control information can include physical layer control information or high layer control information.

[0164] As shown in Fig. 15, the control information is transmitted in a control channel, the control channel or PRDCH is composed of multiple domains. As shown in Fig. 15, the control channel includes domain 0 to domain 2, and the PRDCH includes domain 3 to domain X-1, the whole control information can be transmitted in all the domains 0 to domain X-1, which can be named as control information domain, the control information can be transmitted only in the control information domain, and the control information can include physical layer control information or high layer control information.

[0165] As shown in FIG. 16, the channel for transmitting the control information can have multiple domains, and some of the multiple domains can be configured or indicated by a higher layer or other domains to be enabled. For example, the multiple domains are domain 0 to domain X-1 in FIG. 16, domain 2 is configured or indicated by a higher layer or other domains (domain 0 to domain X-1 except domain 2) to be disabled, domain 2 no longer performs the corresponding function, but the granularity occupied by domain 2 is not changed to ensure that the format or size of the control information does not change. When domain 2 is disabled, the reserve granularities are continued to be filled in domain 2, and these reserve granularities can be written as R bits.

[0166] As shown in FIG. 17, the channel for transmitting the control information can have multiple domains, and some of the multiple domains can be configured or indicated by a higher layer or other domains to be enabled. For example, the multiple domains are domain 0 to domain X-1 in FIG. 17, domain 2 is configured or indicated by a higher layer or other domains (domain 0 to domain X-1 except domain 2) to be disabled, and domain 2 is directly deleted in transmission, occupying 0 granularities.
