Therefore, there is an urgent need to design a method for indicating the content of control information suitable for environmental IoT devices.

[0027] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the system architecture includes: terminal 101 and network device 102; wherein, terminal 101 interacts with network device 103 through network 102.

[0029] It should be noted that the medium providing the communication link between terminal 101 and network device 103 can be a wired network or a wireless network.

[0030] 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.

[0031] Terminal 101 can be a user equipment, terminal equipment, access equipment, user unit, user terminal, or user device, etc.

[0032] 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.

[0033] In this embodiment of the disclosure, terminal 101 can also be a terminal device in an IoT system. IoT connects objects to networks through communication technologies, thereby realizing a smart network that enables human-computer interaction and the interconnection of things. 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).

[0034] In some embodiments, network device 103 may be a base station, relay, or access point, etc. The base station may be, but is not limited to, a 5G or later version base station (e.g., a gNB base station), or a base station in other communication systems (e.g., an eNB base station). It should be noted that the specific type of network-side device is not limited in the embodiments disclosed herein.

[0035] 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 as needed. This disclosure does not limit the scope of the embodiments.

[0036] 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 content of control information specifically for IoT, simplifying the scheduling of IoT devices by network-side equipment.

[0037] However, the 3GPP organization has not yet reached a consensus on what content should be included in the control information of IoT devices. How to design the content of control information for IoT devices has become a pressing technical problem to be solved.

[0038] In order to at least partially solve the above-mentioned technical problems under the above-described system architecture, this disclosure provides a method for indicating control information content of an Internet of Things (IoT) device. This method can be executed by any electronic device with computing capabilities. In some embodiments, the method for indicating control information content of an IoT device provided in this disclosure can be executed by an IoT device within the above-described system architecture; in other embodiments, the method can be implemented by a network-side device (such as a base station) within the above-described system architecture; in still other embodiments, the method can also be implemented through interaction between the network-side device and the IoT device.

[0039] Figure 2 A flowchart illustrating a method for indicating control information content of an Internet of Things (IoT) device according to an embodiment of this disclosure is shown. In one embodiment, such as Figure 2 As shown in the embodiments of this disclosure, the method for indicating control information content of an Internet of Things (IoT) device, applied to a first device, includes the following steps: S202.

[0040] In one embodiment, the first device can be an Internet of Things (IoT) device, the second device is a network-side device, and the control information sent by the second device can also be referred to as R2D control information.

[0041] In one embodiment, the first device can be a network-side device, the second device is an Internet of Things (IoT) device, and the control information sent by the second device can also be called D2R control information.

[0042] In addition, the types of the first and second devices can be determined according to actual needs. For example, when the first device is an IoT device, it can receive control information from another IoT device through a network-side device; or the IoT device can simultaneously receive control information from multiple network-side devices, etc.

[0043] In one embodiment, the first device can perform corresponding operations based on the received control information, such as parameter configuration, data calculation, data forwarding, etc.

[0044] In S202, the D2R transmission may include one of the following transmissions: PDRCH, D2R control information, and reference signal. For example, the D2R transmission may include only PDRCH, or it may include PDRCH and D2R control information; or the D2R transmission may include PDRCH, D2R control information, and reference signal.

[0045] D2R control information can be carried on the PDRCH or in a separately defined new control channel. D2R control information includes acknowledgments of received data blocks, channel quality indications, scheduling requests, and other information.

[0046] A reference signal (RS), also known as a pilot signal, is a known signal provided by the transmitter to the receiver for signal estimation or detection. Reference signals include, but are not limited to, demodulation reference signals, phase tracking reference signals, probe reference signals, and channel state information reference signals.

[0047] In S202, R2D transmission may include one of the following transmissions: PRDCH, R2D control information, reference signal, broadcast information, and paging information. For example, R2D transmission may include only PRDCH, or it may include PRDCH and R2D control information; or R2D transmission may include PRDCH, R2D control information, and reference signal, etc.

[0048] R2D control information is used to schedule user data. It can be carried on the PDRCH or in a separately defined new control channel. R2D control information can include R2D link scheduling allocation and D2R scheduling requests. R2D link scheduling allocation includes control information such as PDRCH resource indication, transmission format, and spatial multiplexing. R2D scheduling requests include information such as PDRCH resource allocation and transmission format.

[0049] Broadcast information is a series of control messages periodically sent by network-side devices to IoT devices within the coverage area of ​​the network-side devices. Broadcast information may include system information blocks, master information blocks, cell-specific reference signals, paging information, and other broadcast information, so that IoT devices can access the network and communicate based on the above information.

[0050] Paging messages can be used to establish and maintain communication connections, as well as to transmit signals or information to users.

[0051] It should be noted that the control information can be any one of the following: transport block information, code rate information, modulation information, coding information, repetitive transmission information, transport block indication information, time domain resource information, frequency domain resource information, candidate resource information, frequency hopping indication information, timeline information, time granularity information, transmission rate information, CP information, synchronization information, measurement information, paging information, power information, and TA information of D2R transmission and / or R2D transmission. It can also be a combination of multiple of the above-mentioned information of D2R transmission and / or R2D transmission. This disclosure does not specifically limit the type and quantity of information of D2R transmission and / or R2D transmission in the control information.

[0052] The following describes the specific content of information transmitted in D2R and / or R2D transmissions.

[0053] In one embodiment, the transport block information for D2R and / or R2D transmissions indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission, or D2R and / or R2D transmissions following the current D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission. The transport block information includes at least one of the following: the size of the transmitted data block; the bit length of the transmitted data; and the time-domain end occupancy position of the transmission. The D2R and / or R2D transmission scheduling can also be referred to as control information indication.

[0054] When the control information is the transport block information of D2R transmission, the transport block information of D2R transmission can indicate the current D2R transmission, the D2R transmission scheduled for the current D2R transmission, or the D2R transmission after the D2R transmission scheduled for the current D2R transmission. That is, the indication object of the transport block information of D2R transmission can be the current D2R transmission or at least one D2R transmission scheduled for the current D2R transmission.

[0055] When the control information is the transport block information for R2D transmission, the transport block information for R2D transmission can indicate the current R2D transmission, the R2D transmission scheduled for the current R2D transmission, or the R2D transmission following the R2D transmission scheduled for the current R2D transmission. That is, the target of the transport block information for R2D transmission can be the current R2D transmission or at least one R2D transmission scheduled for the current R2D transmission.

[0056] When the control information is transport block information for D2R and R2D transmissions, the transport block information for D2R transmissions can indicate the current D2R transmission, the D2R transmission or R2D transmission scheduled for the current D2R transmission, or the D2R transmission and / or R2D transmission following the D2R transmission scheduled for the current D2R transmission, or the D2R transmission and / or R2D transmission following the R2D transmission indicated by the current control information. The indication object of the transport block information for R2D transmissions is similar to that of the transport block information for D2R transmissions, and will not be elaborated here.

[0057] It should be noted that the target of the control information instruction for the first device can be determined according to the actual situation.

[0058] A transport block is a data block that is transmitted in each transmission. It is the basic unit of uplink and downlink transmission.

[0059] The transmitted data block size represents the number of data blocks required to transmit control information; the transmitted bit length represents the number of binary bits required for the transmitted control information; and the transmission time-domain end position represents the value of the last time point of the transmitted block information. The transmission time-domain end position can be implicitly indicated, for example, by using the transmission block size and / or the transmission block's time-domain start position.

[0060] In one embodiment, the bitrate information of the D2R and / or R2D transmission indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission following the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission. The bitrate information includes at least one of the following: bitrate size; bitrate encoding type.

[0061] It should be noted that the method for determining the indicator object of the bit rate information in D2R transmission and / or R2D transmission is the same as that for determining the indicator object of the transport block information, which will not be elaborated here.

[0062] In one embodiment, the bit rate is used to characterize the speed at which the control information is transmitted. The bit rate may include 1, 0.5, 0.25, 0.125, 0.0625, 0.03125, 0.015625, or no indication.

[0063] The encoding type of bitrate is used to characterize the encoding method of bitrate. The encoding types of bitrate can include linear code, forward error correction (FEC) code, cyclic redundancy check (CRC) code, or no code.

[0064] Linear coding can include Manchester codes, Miller codes, bidirectional spaced codes (FM0 codes), etc. Forward error correction coding can use convolutional codes, including zero-tailed convolutional codes (ZTCC) or tail-biting convolutional codes (BTCC). ZTCC adds K (K is the constraint length) zeros to the codeword to output the final state of the encoding register. BTCC directly initializes the encoding register with the last K bits of the codeword to improve the coding rate. Cyclic redundancy check (CRC) codes can be 6-bit or 16-bit CRC codes, etc.

[0065] It should be noted that the bitrate and encoding type of the control information can be pre-configured, and the specific information can be determined according to the actual situation. This disclosure does not impose any specific restrictions on this.

[0066] In one embodiment, the encoding information of the D2R transmission and / or R2D transmission indicates the current D2R transmission and / or R2D transmission, the D2R transmission and / or R2D transmission scheduled for the current D2R transmission and / or R2D transmission, or the D2R transmission and / or R2D transmission following the current D2R transmission and / or R2D transmission scheduled for the current D2R transmission and / or R2D transmission. The encoding information includes at least one of the following: encoding type and encoding method.

[0067] The coding types include at least one of linear coding, forward error correction coding, cyclic redundancy check coding, and no coding.

[0068] The encoding methods for R2D transmission include linear encoding, forward error correction encoding, or cyclic redundancy check (CRC) coding. Linear encoding for R2D transmission includes at least one of Manchester code, Pulse Interval (PIE) encoding, or no encoding. Forward error correction encoding for R2D transmission includes at least one of convolutional code, Low Density Parity Check (LDPC) code, Polar code, Concatenated Turbe code, parity check code, or no encoding. CRC coding for R2D transmission includes at least one of 6-bit CRC, 16-bit CRC, or no CRC. For example, R2D transmission may use a combination of Manchester code (linear encoding) and convolutional code (forward error correction), or a combination of PIE encoding (linear encoding) and 6-bit CRC. Convolutional codes may include ZTCC or BTCC.

[0069] The encoding methods for D2R transmission include linear encoding, forward error correction encoding, or cyclic redundancy check (CRC) codes. Linear encoding for D2R transmission includes at least one of Manchester codes, bidirectional spacing FM0 codes, Miller codes, or no encoding. Forward error correction encoding for D2R transmission includes at least one of convolutional codes, LDPC codes, Polar codes, Turbe codes, parity check codes, or no encoding. CRC codes for D2R encoding include at least one of 6-bit CRC, 16-bit CRC, or no CRC. For example, D2R encoding may use a combination of Manchester codes and LDPC codes, or a combination of FM0 codes and parity check codes. Convolutional codes may include ZTCC or BTCC.

[0070] Among them, the linear coding, forward error correction coding or cyclic redundancy check code of R2D or D2R transmission includes generative multiplexing of New Radio (NR), generative multiplexing of Radio Frequency Identification (RFID), or generative indication in the encoded information.

[0071] Encoding information is used to characterize the encoding method for different targets. When the control information includes encoding information from R2D transmission, Manchester code, PIE encoding, or no encoding can be used alone, or Manchester code and PIE encoding can be used together. Correspondingly, when the control information includes encoding information from D2R transmission, linear encoding, forward error correction encoding, or cyclic redundancy check (CRC) code can be used alone, or a combination of at least two of the above encoding methods can be used.

[0072] It should be noted that the indication object of the encoded information in D2R transmission and / or R2D transmission is determined in the same way as the indication object of the aforementioned transport block information, and will not be repeated here.

[0073] In one embodiment, the modulation information of the D2R and / or R2D transmission indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission following the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission. The modulation information includes at least one of the following modulation schemes: Binary On-Off Keying (OOK); Frequency-Shift Keying (FSK); Binary Phase Shift Keying (BPSK).

[0074] OOK, also known as binary amplitude keying, uses a unipolar non-return-to-zero code sequence to control the on and off of a sinusoidal carrier wave. For example, one amplitude represents logic 0, and the other amplitude represents logic 1.

[0075] FSK is a modulation method that uses digital signals to control the carrier frequency. Based on whether the phase of the modulated wave is continuous, FSK is divided into phase-discontinuous FSK and phase-continuous FSK. For example, a higher frequency can represent logic 1, and a lower frequency can represent logic 0.

[0076] BPSK is a conversion method that transforms analog signals into data values, using a combination of complex waves with out-of-phase characteristics to represent information keying phase shifting. For example, BPSK uses a reference sine wave and phase-reversed waves, with the sine wave representing logic 0 and the phase-reversed waves representing logic 1.

[0077] In one embodiment, when the modulation scheme is OOK, the method further includes: indicating OOK, wherein the indication content includes at least one of the following: The M value of OOK is the number of chips that can be used in each OFDM symbol; OOK chip rate; OOK requires at least one of the following: sequence type, sequence generation parameters, and sequence length; The chip length of OOK.

[0078] It should be noted that the value of M can be a specific integer from 1 to 32. For example, M can be at least one of 1, 2, 4, 8, 16, and 32.

[0079] Chip rate is the symbol rate after spread spectrum. Spread spectrum is the process of multiplying user data symbols with their corresponding spreading codes. Spread spectrum increases the signal bandwidth and can convert bits into chips.

[0080] In OOK modulation, binary bits can be encoded into a series of pulses or time intervals, the width of which can represent 0 or 1. OOK sequence generation parameters can include pulse width or time interval length, where the pulse width can be considered the chip length of the OOK, such as 256 sampling points or 41.67 µs. The OOK sequence length is the length of the sequence used for spread spectrum operation; for example, for a 1 RB bandwidth IoT signal, the spread spectrum sequence length is 1 RB, or 12 units. The spread spectrum sequence is generally a constant-mode sequence with the same magnitude but different phases.

[0081] In one embodiment, when the modulation method uses FSK, the method further includes: indicating FSK, wherein the indication content includes at least one of a target frequency value and a frequency shift value.

[0082] In FSK modulation, two frequencies, f1 and f2, are used as target frequency values, and f1 and f2 are different carrier frequencies. When transmission logic is 0, the carrier with frequency f1 is transmitted; when transmission logic is 1, the carrier with frequency f2 is transmitted. The frequency shift value is the difference between f2 and f1, used to characterize the ease with which multiple waveforms of the same energy can be distinguished as signals.

[0083] In one embodiment, the retransmission information for D2R and / or R2D transmissions indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission following the current D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission. The retransmission information includes at least one of the following: the number of retransmissions; and the granularity of the retransmission.

[0084] The indication object for repeated transmission information in D2R and / or R2D transmissions is the same as the method for determining transmission block information in the aforementioned embodiments, and will not be repeated here.

[0085] The number of retransmissions can be determined based on whether retransmission is required during the information transmission process, such as signals under timeout retransmission or fast retransmission.

[0086] The granularity of repeated transmission includes transport block level, bit level, and chip level. Transport block level refers to a repeat transmission where the unit of repetition is a transport block; that is, a repeat transmission occurs after one transport block is completed. Chip level refers to a repeat transmission where the unit of repetition is a chip; that is, a repeat transmission occurs immediately after each chip transmission is completed.

[0087] Bit-level refers to the repetition unit being a single bit, meaning that each bit is repeated after it has been transmitted. Considering that bits may undergo linear and / or FEC encoding, leading to inconsistencies with the source bitstream, bit-level repetition transmission can be further divided into transmitting each bit before linear and / or FEC encoding, or transmitting each bit after linear and / or FEC encoding.

[0088] In one embodiment, the transmission block indication information for D2R and / or R2D transmissions indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmissions following the current D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission. The transmission block indication information is used to characterize whether the transmission is a single transmission or a segmented transmission. For example, in a D2R transmission, if the length of the transmission block exceeds the predefined or preconfigured network-side time-domain detection window length, segmented transmission is required to avoid detection failure and impact on other signals.

[0089] The indication objects of the transmission segmentation indication information for D2R transmission and / or R2D transmission are determined in the same way as the transmission block information in the aforementioned embodiments, and will not be repeated here.

[0090] The transmission segmentation indication information can be 1 bit. For example, bit 1 indicates segmented transmission and bit 0 indicates one-time transmission, or bit 0 indicates segmented transmission and bit 1 indicates one-time transmission.

[0091] In one embodiment, the time-domain resource information of the D2R and / or R2D transmission indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission following the current D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission. The time-domain resource information includes at least one of time-domain resource length and time-domain resource location information.

[0092] The indication object of the time domain resource information for D2R transmission and / or R2D transmission is the same as the method for determining the transport block information in the aforementioned embodiments, and will not be repeated here.

[0093] The time-domain resource length, also known as the time-domain resource size, is used to represent the amount of time-domain resources occupied during transmission and can also be used to implicitly indicate the end position of the time domain. In 5G NR, the time-domain resource length includes radio frames, subframes, time slots, and OFDM symbols. A radio frame is 10ms long, and one radio frame includes 10 subframes. One time slot includes 14 OFDM symbols. It should be noted that the NR time-domain resource length can be reused in the IoT communication system disclosed herein.

[0094] The time-domain resource location information includes start location information and / or end location information. For example, the time-domain resource location information may include only start location information or end location information, or it may include both start location information and end location information.

[0095] The starting position information includes: absolute starting position information; absolute starting position information within a preset first time granularity; offset information of the starting or ending position relative to the current configuration information at a preset second time granularity; or, when the indication information is transmitted periodically, offset information of the starting or ending position relative to the most recent transmission cycle position of the indication information at a preset third time granularity.

[0096] The absolute start position information can indicate the start position of the Xth granularity R2D or D2R transmission, where X is an offset value relative to the absolute position. For example, the Xth granularity is the 273rd chip, used to express the start position corresponding to the 273rd chip.

[0097] The aforementioned absolute starting position information within the preset first time granularity can, for example, indicate the Y-th chip within an OFDM symbol as the absolute starting position.

[0098] The offset information in the preset second time granularity offset position relative to the start or end position of the current configuration information, and the offset information in the preset third time granularity offset position relative to the most recent transmission cycle position of the indication information when the indication information is periodically transmitted, includes: The preset granularity value is a fixed value, for example, the offset information is Z granularities, where Z is a natural number; The minimum time interval granularity from the current configuration information to the R2D or D2R transmission represents the minimum value Tmin from the current configuration information to the R2D or D2R transmission. The granularity of the maximum time interval from the current configuration information's current location to the R2D or D2R transmission represents the maximum value Tmin from the current configuration information's current location to the R2D or D2R transmission; or The transmission from the current configuration information to the offset time of R2D or D2R transmission needs to be carried out within a preset time range, which can be configured as [Tmin, Tmax].

[0099] It should be noted that the aforementioned preset granularity value, minimum time interval granularity, maximum time interval granularity, and preset time interval can be pre-configured, and the specific values ​​can be determined according to actual needs. This disclosure does not impose any restrictions on this.

[0100] The end position information includes: absolute end position information; absolute end position information within a preset fourth time granularity; offset information of the start or end position relative to the current configuration information at a preset fifth time granularity; or, when the indication information is transmitted periodically, offset information of the start or end position relative to the most recent transmission cycle position of the indication information at a preset sixth time granularity.

[0101] The absolute end position information can indicate the end position of the Mth granularity R2D or D2R transmission, where M is an offset relative to the absolute position. For example, M granularities are 273 chips, used to indicate the end position corresponding to the 273rd chip.

[0102] The absolute end position information within the fourth time granularity is preset, for example, it can indicate the Nth chip in an OFDM symbol as the end position.

[0103] The offset information at the preset fifth time granularity relative to the start or end position of the current configuration information; or when the indication information is periodically transmitted, the offset information at the preset sixth time granularity relative to the start or end position of the nearest transmission cycle position of the indication information includes: a preset granularity value; the minimum time interval granularity from the current configuration information to the R2D or D2R transmission; the maximum time interval granularity from the current configuration information to the R2D or D2R transmission; or the offset time from the current configuration information to the R2D or D2R transmission that needs to be transmitted within a preset time interval. The definition of offset information is the same as the aforementioned, and will not be repeated here.

[0104] It should be noted that the second, third, fourth, fifth, and sixth time granularities are all time granularity units, such as OFMD symbols, time slots, and OOK chips.

[0105] In one embodiment, the frequency domain resource information of D2R transmission and / or R2D transmission indicates the current D2R transmission and / or R2D transmission, the D2R transmission and / or R2D transmission scheduled for the current D2R transmission and / or R2D transmission, or the D2R transmission and / or R2D transmission after the D2R transmission and / or R2D transmission scheduled for the current D2R transmission and / or R2D transmission. The frequency domain resource information includes: frequency resources occupied by the transmission, starting position information of the frequency resources, frequency resource mapping method, transmission carrier frequency information, or subcarrier spacing information.

[0106] It should be noted that the indication object of the frequency domain resource information for D2R transmission and / or R2D transmission is determined in the same way as the indication object of the aforementioned transport block information, and will not be repeated here.

[0107] The frequency resources occupied by transmission include transmission bandwidth and / or guard bandwidth. Transmission bandwidth refers to the amount of frequency resources occupied during signal transmission. Guard bandwidth does not contain signals and is used to isolate IoT signals from other signals.

[0108] The starting position information of frequency domain resources includes absolute starting position information and / or frequency offset information.

[0109] The absolute start position information can be P1 Hz, P2 RE, or P3 RB. P1, P2, and P3 are determined based on the actual situation. RE (Resource Element) is the smallest physical resource unit in a communication network; one resource element corresponds to one symbol period of one subcarrier. RB (Resource Block) is the basic unit used for data transmission in a communication network; one resource block includes multiple subcarriers and multiple symbol periods, and an RB is composed of multiple REs.

[0110] Frequency offset information is the offset relative to the previous frequency. For example, define an offset (offset), and the target frequency position is the sum of the current frequency position information and the offset.

[0111] Frequency resource mapping methods include continuous frequency resource mapping or segmented continuous frequency resource mapping. Continuous frequency resource mapping means the allocated frequency resources are continuous; segmented continuous frequency resource mapping means the allocated frequency resources are continuous in segments. For example, if the allocated frequency resources take into account the protection bandwidth, then the allocated frequency resources are the non-protection bandwidth frequency resources, meaning the allocated frequency resources are segmented and continuous.

[0112] The carrier frequency information transmitted is used to characterize the magnitude of the carrier frequency currently being transmitted.

[0113] Subcarrier spacing information characterizes the subcarrier spacing of the current transmission. It can directly indicate the numerical value of the subcarrier spacing or indicate parameter set numerology information. Subcarrier spacing information can include at least one of 3.75 kHz, 7.5 kHz, 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz. Numerology refers to the parameter set, which can include subcarrier spacing, symbol length, CP length, etc.

The candidate resource information includes: the ordinal information of the candidate resources; the maximum number of candidate resources; and / or the available data information of the candidate resources.

[0115] It should be noted that the indication object of the candidate resource information for D2R transmission and / or R2D transmission is determined in the same way as the indication object of the transport block information in the above embodiments, and will not be repeated here.

[0116] Candidate resources refer to alternative resources selected from all available resources in a communication system according to certain rules or algorithms for use in subsequent communication processes (such as data transmission, signal transmission, etc.). Resources can include time-domain resources, code resources, spatial resources, frequency-domain resources, etc.

[0117] Candidate resource selection rules or algorithms can include resource pool-based selection, channel condition-based ranking, or transmission rank-based determination. For example, resource pool-based selection can monitor the availability of resources in the pool and select candidate resources based on preset configuration information. Channel condition-based ranking can perform channel quality assessment on resources in the pool, rank the resources according to the assessment results, and select the top 5 resources based on channel quality as candidate resources. Transmission rank-based determination can select a group of resources that meet the transmission rank requirements from the candidate resource set as candidate resources, where transmission rank represents the parallel data stream or antenna configuration during transmission.

[0118] In one embodiment, the candidate resources include at least a set of time-domain resources or frequency-domain resources, and the set of multiple candidate resources is called the candidate resource set. The candidate resource set may record the resource type of the candidate resources and the position of each candidate resource within the set, wherein the position of a candidate resource within the set can be represented by its ordinal number. For example, the A1th candidate resource is the A1th candidate resource in the candidate resource set.

[0119] The maximum number of candidate resources refers to the maximum number of candidate resources in the candidate resource set. For example, the maximum number of candidate resources in the candidate resource set is A2.

[0120] The available quantity information of candidate resources represents the number of candidate resources that are active or available for selection in the candidate resource set. For example, the available quantity of candidate resources includes A3.

[0121] The ordinal number A1, the maximum number of candidate resources A2, and the available number of candidate resources A3 can be determined according to the actual situation, and this disclosure does not impose specific restrictions on them.

[0122] In one embodiment, the frequency hopping indication information for D2R and / or R2D transmissions indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmissions following the current D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmissions. The frequency hopping indication information includes at least one of the following: frequency hopping enable information and frequency hopping count information.

[0123] It should be noted that the indication object of the frequency hopping indication information of D2R transmission and / or R2D transmission is determined in the same way as the indication object of the transmission block information in the aforementioned embodiments, and will not be repeated here.

[0124] Frequency hopping technology refers to frequency shift keying using pseudo-random code sequences, which is a technique that expands the spectrum by continuously changing the carrier frequency.

[0125] Frequency hopping enable information is used to indicate whether D2R and / or R2D transmissions support frequency hopping. For example, if the frequency hopping enable information is enabled, it means that D2R and / or R2D transmissions support frequency hopping; if the frequency hopping enable information is disabled, it means that D2R and / or R2D transmissions do not support frequency hopping.

[0126] Frequency hopping count information indicates the number of frequency hopping operations in D2R and / or R2D transmissions. When using frequency hopping technology for communication, the transmission signal bandwidth can be divided into multiple sub-frequency units, which are continuously hopped at the receiving and transmitting ends according to a pre-agreed frequency. The parameters of the frequency hopping signal can include the hopping period and hopping rate. The frequency hopping count is calculated based on the hopping period and hopping rate.

[0127] In one embodiment, the timeline information for D2R and / or R2D transmissions indicates the time relationship between the current D2R and / or R2D transmission and the D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission, or indicates the time relationship between the current D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission and the next potential D2R and / or D2D transmission. The timeline information includes at least one of the following: time interval information, time interval size, and time interval characteristics.

[0128] The timeline information for D2R and / or R2D transmissions indicates the time relationship between the current D2R and / or R2D transmission and its scheduled D2R and / or R2D transmissions. D2R and / or R2D transmissions can be D2R and R2D transmissions, or R2D and D2R transmissions, or two D2R transmissions or two R2D transmissions. Two D2R transmissions or two R2D transmissions can be consecutive or discontinuous.

[0130] In one embodiment, the time interval information includes the maximum time interval between the R2D transmission and the subsequent D2R transmission. The maximum time interval can be the time interval from the last time granularity of the R2D transmission (e.g., the PRDCH transmission) to the first time granularity of the target D2R transmission, or it can be the time interval from the last time granularity of the postlead sync code of the R2D transmission (e.g., the PRDCH transmission) to the first time granularity of the target D2R transmission.

[0131] In one embodiment, the time interval information includes the minimum time interval between a D2R transmission and a subsequent R2D transmission. This minimum time interval can be the time interval between the last time granularity of a D2R transmission (e.g., a PDRCH transmission) and the first time granularity of the target R2D transmission, or it can be the time interval between the last time granularity of the post-synchronization code of a D2R transmission (e.g., a PDRCH transmission) and the first time granularity of the target R2D transmission.

[0132] In one embodiment, the time interval information includes the maximum time interval between a D2R transmission and a subsequent R2D transmission. This maximum time interval can be the time interval between the last time granularity of a D2R transmission (e.g., a PDRCH transmission) and the first time granularity of the target R2D transmission, or it can be the time interval between the last time granularity of the post-synchronization code of a D2R transmission (e.g., a PDRCH transmission) and the first time granularity of the target R2D transmission.

[0133] In one embodiment, the time interval information includes: the minimum time interval between two R2D transmissions. This minimum time interval can be the time interval from the last time granularity of an R2D transmission (e.g., a PRDCH transmission) to the first time granularity of the next R2D transmission; or it can be the time interval from the last time granularity of the postlead synchronization code of an R2D transmission (e.g., a PRDCH transmission) to the first time granularity of the next R2D transmission.

[0134] It should be noted that two R2D transmissions can be consecutive or discontinuous. For example, the time interval between two R2D transmissions can be the time interval between the first and third R2D transmissions. Preferably, the time interval between two R2D transmissions can be the time interval between consecutive R2D transmissions, that is, the time interval between the first and second R2D transmissions.

[0135] In one embodiment, the time interval information includes: the maximum time interval between two R2D transmissions. This maximum time interval can be the time interval from the last time granularity of an R2D transmission (e.g., a PRDCH transmission) to the first time granularity of the next R2D transmission; or it can be the time interval from the last time granularity of the postlead synchronization code of an R2D transmission (e.g., a PRDCH transmission) to the first time granularity of the next R2D transmission.

[0136] It should be noted that two R2D transmissions can be consecutive or discontinuous. For example, the time interval between two R2D transmissions can be the time interval between the first and third R2D transmissions. Preferably, the time interval between two R2D transmissions can be the time interval between consecutive R2D transmissions, that is, the time interval between the first and second R2D transmissions.

[0137] In one embodiment, the time interval information includes: the minimum time interval between two D2R transmissions. This minimum time interval can be the time interval from the last time granularity of a D2R transmission (e.g., a PDRCH transmission) to the first time granularity of the next D2R transmission, or the time interval from the last time granularity of the post-synchronization code of a D2R transmission (e.g., a PDRCH transmission) to the first time granularity of the next D2R transmission.

[0138] It should be noted that the time interval between two D2R transmissions can be different D2R time interval requirements. For example, in a multi-access system, it can be the time interval requirement between the D2R transmissions of the first IoT device and the second IoT device, or it can be the time interval requirement between the D2R transmissions of the first IoT device and the third IoT device, used to express the minimum distance between the transmissions of two IoT devices. Preferably, it is the time interval between the first D2R transmission and the second D2R transmission of the same IoT device.

[0139] In one embodiment, the time interval information includes the maximum time interval between two D2R transmissions. This maximum time interval can be the time interval from the last time granularity of a D2R transmission (e.g., a PDRCH transmission) to the first time granularity of the next D2R transmission, or the time interval from the last time granularity of the post-synchronization code of a D2R transmission (e.g., a PDRCH transmission) to the first time granularity of the next D2R transmission.

[0140] It should be noted that the time interval between two D2R transmissions can be different D2R time interval requirements. For example, in a multi-access system, it can be the time interval requirement between the D2R transmissions of the first IoT device and the second IoT device, or it can be the time interval requirement between the D2R transmissions of the first IoT device and the third IoT device, used to express the maximum distance between the transmissions of two IoT devices. Preferably, it is the time interval between the first D2R transmission and the second D2R transmission of the same IoT device.

[0141] It should be noted that the meanings of the maximum and minimum time intervals in the above time interval information are merely examples provided to illustrate the embodiments of this disclosure and should not be regarded as limitations on the scope of protection of this disclosure. Other combinations and transformations of parameters may also be used as needed and are also within the scope of protection of this disclosure. For example, the time interval between the first time granularity of the preamble synchronization code of the R2D transmission (e.g., PRDCH transmission) and the first time granularity of the target D2R transmission is not specifically limited in this disclosure.

[0142] The time interval size is used to characterize the number of time granularities occupied by the time interval, for example, the time interval size is B time granularities.

[0143] The characteristics of time intervals can be categorized into time intervals based on different types of IoT devices, time intervals based on different types of services, time intervals based on different types of commands, or time intervals based on different use cases.

[0144] It should be noted that the values ​​of the time intervals mentioned above for different types can be the same or different, and this disclosure does not limit this.

[0145] In one embodiment, the time granularity information of the D2R and / or R2D transmission indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission and the subsequent D2R and / or R2D transmission. The time granularity information includes a time granularity value and / or a time granularity unit.

[0146] It should be noted that the indication object of the time granularity information of D2R transmission and / or R2D transmission is determined in the same way as the indication object of the transmission block information in the aforementioned embodiments, and will not be repeated here.

[0147] The time granularity unit includes at least one of the following: OFDM frame, OFDM subframe, OFDM symbol, OFDM slot, microsecond, sampling point, OOK chip, PRDCH chip, PRDCH symbol, PRDCH slot, PRDCH sampling point, PDRCH chip, PDRCH symbol, PDRCH slot, PDRCH sampling point, R2D chip, R2D symbol, R2D slot, R2D sampling point, D2R chip, D2R symbol, D2R slot, and D2R sampling point.

[0148] The time granularity value is used to characterize the number of time granularities occupied by control information. For example, the time granularity value is C time granularities.

[0149] The unit of time granularity is the basic unit of time. The unit of time granularity can be any one of the basic units mentioned above, or it can include multiple of the basic units mentioned above.

[0150] When a time granularity unit comprises multiple basic units, the time granularity unit may include multiple identical basic units, such as a time granularity unit comprising two chips; the time granularity unit may also include different basic units, such as a time granularity unit comprising a combination of a chip and an OFDM symbol. For example, a time granularity unit can be defined as the sum of the durations of a low-level chip and a high-level chip.

[0151] In NR communication, the frame structure consists of frames, subframes, slots, and symbols. A frame is 10ms long and contains 10 subframes, each 1ms long. The slot and symbol lengths can be flexibly defined based on the subcarrier spacing.

[0152] A slot, also known as a time unit, includes slots such as OFDM slots, PRDCH slots, PDRCH slots, R2D slots, and D2R slots. In NR systems, 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 one slot or subframe, and each slot lasts 1ms; when μ=1, there are two slots or subframes, and each slot lasts 0.5ms; when μ=2, there are four slots or subframes, and each slot lasts 0.25ms; when μ=3, there are eight slots or subframes, and each slot lasts 0.125ms; and when μ=4, there are 16 slots or subframes, and each slot lasts 0.0625ms.

[0153] A symbol, also known as a time-domain symbol, can be combined with other multiple access methods for naming. The length of a time-domain symbol can vary depending on the subcarrier spacing. Examples include OFDM symbols, R2D symbols, and D2R symbols mentioned above. Typically, each slot includes 14 OFDM symbols.

[0154] 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.

[0155] 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.

[0156] 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 AA μs, where AA is a specific numerical value. For example, the time granularity of PDRCH is defined as 44.4 μs.

[0157] In one embodiment, the transmission rate information of D2R and / or R2D transmission indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission following the current D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission. The transmission rate information includes at least one of the following: data rate information; bit rate information; chip rate information; M-value information.

[0158] The method for determining the indication object of the transmission rate information for D2R and / or R2D transmissions is similar to that for determining the indication object of the transmission block information in the aforementioned embodiments, and will not be repeated here.

[0159] Data rate information is used to characterize the speed of data transmission per unit time. For example, it can be measured in bits by the amount of information transmitted per unit time on D2R and / or R2D transmission channels.

[0160] Bit rate information, also known as bit rate, is used to characterize the number of bits transmitted through a channel per unit time, and directly determines the speed and efficiency of data transmission.

[0161] Chip rate information is used to indicate the number of chips transmitted per unit time.

[0162] M-value information is used to characterize the amount of information that each chip can carry. M-value is a numerical value of different discrete values ​​that a chip or symbol can take. For example, M-value includes a specific integer from 1 to 16. Preferably, M-value is at least one of 1, 2, 4, 8, and 16. M-value affects the data transmission rate and efficiency.

[0163] In one embodiment, the Cyclic Prefix (CP) information of the D2R and / or R2D transmission indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission following the current D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission. The CP information includes CP length information, CP type information, and / or CP enable information.

[0164] The indication object of CP information for D2R transmission and / or R2D transmission is similar to the method of determining the indication object of transport block information in the aforementioned embodiments, and will not be repeated here.

[0165] The cyclic prefix (CP) can copy the signal from the tail of an OFDM symbol to the head, thereby reducing or eliminating inter-symbol interference caused by multipath propagation.

[0166] CP type information can include a regular cyclic prefix and an extended cyclic prefix. For example, the length of the regular cyclic prefix is ​​4.7 μs and the length of the extended cyclic prefix is ​​16.67 μs.

[0167] CP length information represents the length value of the cyclic prefix. When all CP lengths are the same, the CP length information can indicate the size of the currently transmitted CP length, for example, B time granularities. When some CP lengths are different, the CP length information indicates the CP length values ​​of the different CP lengths and / or the lengths of the remaining CP lengths that are the same. The CP length information can also indicate the number of CPs with the same length and / or the number of CPs with different lengths.

[0168] CP enable information is used to indicate whether the current transmission has added CP. For example, when the CP enable information is 1, it means that the current transmission has added CP, and when the enable information is 0, it means that the current transmission has not added CP.

[0169] In one embodiment, the synchronization information of D2R and / or R2D transmissions indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmissions following the D2R and / or R2D transmissions scheduled for the current D2R and / or R2D transmission. The synchronization information includes at least one of the following: the generation density of the intermediate synchronization code and the generation structure of the intermediate synchronization code.

[0170] The indication object of the synchronization information for D2R transmission and / or R2D transmission is determined in the same way as the indication object of the transmission block information in the foregoing embodiments, and will not be repeated here.

[0171] The generation density of intermediate synchronization codes refers to the number of time granularities between each insertion of an intermediate synchronization code. The generation density of intermediate synchronization codes is based on a preset number of time granularities to insert one intermediate synchronization code. The preset number can be determined according to actual needs and is pre-configured in the second device. The preset number takes a value within a preset range, for example, between 1 and 20.

[0172] The preset quantity is calculated starting from the first time granularity of the preamble, the last time granularity of the preamble, or the first time granularity of the R2D or D2R transmission after the preamble.

[0173] like Figure 3 As shown, the preset quantity is 4. When the calculation starts from the first time granularity of the preamble, intermediate synchronization codes can be inserted at the 5th, 10th, and 15th time granularities, respectively.

[0174] For example, if the preset number is 4, when the calculation starts from the last time granularity of the preamble (e.g., the 15th time granularity), intermediate synchronization codes can be inserted at positions such as the 20th time granularity and the 25th time granularity.

[0175] The preset quantity is calculated starting from the first time granularity of R2D or D2R transmission after the preamble synchronization code. The above example can be used as a reference, and it will not be repeated here.

[0176] The generation structure of intermediate synchronization codes includes intermediate synchronization codes that are all the same, or intermediate synchronization codes that perform a specific function that have different generation methods from the target intermediate synchronization code.

[0177] It should be noted that at least one intermediate synchronization code can be inserted during transmission. When multiple intermediate synchronization codes are inserted, all intermediate synchronization codes are identical. For example, an intermediate synchronization code may be generated solely from a sequence, or it may consist of other information, or it may be composed of both a sequence and other information. This other information could include clock information, etc.

[0178] In one embodiment, when multiple intermediate synchronization codes are inserted, the multiple intermediate synchronization codes may include at least one intermediate synchronization code that performs a specific function. The at least one intermediate synchronization code that performs a specific function is generated differently from the target synchronization code. The target synchronization code is the intermediate synchronization code other than the at least one intermediate synchronization code that performs a specific function. The specific function may include measurement, channel estimation, etc.

[0179] For example, intermediate synchronization codes for performing a specific function can be generated every B1 time granularities.

[0180] like Figure 4 As shown, when calculations are performed starting from the first time granularity of the preamble, intermediate synchronization codes can be inserted at the 5th, 10th, 15th, and 20th time granularities, respectively. Among them, intermediate synchronization codes for performing specific functions are inserted at the positions corresponding to the 10th and 20th time granularities.

[0181] For example, an intermediate synchronization code for performing a specific function can be generated every B2 intermediate synchronization codes. For instance, when calculations are performed starting from the first time granularity of the preceding synchronization code, intermediate synchronization codes can be inserted at the 5th, 10th, 15th, and 20th time granularities, respectively. If an intermediate synchronization code for performing a specific function is generated every 2 intermediate synchronization codes, then the intermediate synchronization code for performing the specific function will be inserted at the positions corresponding to the 15th and 30th time granularities.

[0182] It should be noted that other intermediate synchronization code generation rules can also be used to generate intermediate synchronization codes for specific functions, and this disclosure does not impose any specific limitations.

[0183] In one embodiment, the measurement information of the D2R and / or R2D transmission indicates the current D2R and / or R2D transmission, the D2R and / or R2D transmission scheduled for the current D2R and / or R2D transmission, or the D2R and / or R2D transmission following the current D2R and / or R2D transmission. The measurement information includes at least one of the following: a measurement signal generated using a constant modulus sequence; a measurement interval; a measurement index; a measurement method; a measurement bandwidth; and a measurement location.

[0184] Measurement information is used to indicate the object being measured and related measurement parameters, so that the first device can perform measurement operations based on the measurement information.

[0185] The measurement signals include preamble synchronization codes, intermediate synchronization codes, postamble synchronization codes, or reference signals. The constant mode sequences include Zadoff-Chu sequences, maximum length sequences (M sequences), pseudo-random sequences (Gold sequences), constant envelope zero autocorrelation sequences (CGS sequences), primary synchronization signals (PSS sequences), secondary synchronization signals (SSS sequences), quadrature phase shift keying (QPSK) sequences, PN sequences, Reid-Mahler sequences (RM sequences), low peak-to-average power ratio (PAPR) sequences, or Gray sequences.

[0186] Preamble, intermediate, and postamble synchronization codes are used to perform synchronization measurements, while reference signals are used to ensure accurate transmission and reception of communication signals.

[0187] It should be noted that the constant modulus sequence used to generate the measurement signal can employ at least one of the aforementioned basic sequences. These basic sequences can be ZC, M, Gold, CGS, PSS, SSS, QPSK, PN, RM, PAPR, or Gray sequences. It is understood that the measurement signal can include a sequence generated from one or more of these basic sequences. When multiple basic sequences are used to generate the measurement signal, they can include multiple identical basic sequences (e.g., multiple ZC sequences) or multiple different basic sequences (e.g., at least one ZC sequence and at least one CGC sequence).

[0188] The measurement metrics include at least one of IoT-RSRP, IoT-RSRQ, IoT-SINR, and IoT-proximity. IoT-RSRP (Reference Signal Receiving Power) characterizes the corresponding signal strength on the IoT device; IoT-RSRQ (Reference Signal Receiving Quality) characterizes the signal strength on the IoT device across the entire bandwidth and the level of interference from other IoT devices; IoT-SINR (Signal to Interference plus Noise Ratio) characterizes the channel quality on the IoT device; and IoT-proximity measures the distance between the IoT device and network-side devices.

[0189] The measurement method includes measuring 1 chip and / or 0 chip of each measurement signal. The measurement method indicates whether the measurement is performed on 1 chip, 0 chip, or all chips. Among them, 1 chip is also called ON chip, and 0 chip is also called OFF chip.

[0190] Measurement bandwidth, also known as IoT bandwidth, can be configured as a separate measurement signal bandwidth or can be implemented depending on the terminal device.

[0191] Measurements are performed on network-side devices, not on IoT devices. For example, for a single cell, measurements can be taken within that cell; for carrier aggregation or dual connectivity, measurements can be taken on the Pcell (Primary cell).

[0192] The measurement interval, also known as the measurement period, is, for example, measured at a time granularity of X, or determined by the period of the preamble, intermediate, or postamble synchronization codes and the actual enabling status.

The power information includes at least one of the following: the maximum transmit power of the IoT device; open-loop power control information; power margin information; and power adjustment information.

[0197] The maximum transmit power of an IoT device is used to characterize the maximum allowable transmit power of the IoT device, or is reported by the IoT device to characterize the maximum transmit power information referenced by the IoT device.

[0198] Open-loop power control information is used to configure or indicate the base values ​​of the current IoT device power, such as p0 or alpha.

[0199] Power margin information is used to characterize the maximum margin allowed for the IoT device from the maximum transmit power, or is reported by the IoT device to characterize the difference between the IoT device and the maximum transmit power referenced by the device.

[0200] Power adjustment information indicates that the IoT device needs to adjust its power value from the current power level to avoid or resist excessive interference. The indicated value can be in the form of an offset or a proportional value. For example, if the power adjustment information indicates an offset value, the adjusted power of the IoT device is the difference between the current power and the offset value.

[0201] Power adjustment information may include at least one of the following: power ramping information, transmission power control (TPC) information, power factor information, and power concentration transmission information.

[0202] In one embodiment, TA information includes timing advance information, or timing advance information and target IoT device identification information. TA information is used to adjust the timing of signal transmission to ensure that the signal arrives at the receiver at the expected time. Specific TA information can be used to align the start boundaries of symbols or to distinguish between several TDM-accessed IoT signals. TA can be a fixed value or a range value. If it is a range value, the value can be between 0 and 100 µs.

[0203] The target IoT device can be another IoT device that communicates with the current IoT device (if the first device is an IoT device, then the first device is the current IoT device), or it can be an IoT device that may communicate with the current IoT device. The target IoT device identification information is used to distinguish different IoT devices.

[0204] It should be noted that the indication object of the information in D2R transmission and / or R2D transmission is determined in the same way as the indication object of the transmission block information in the aforementioned embodiments, and will not be repeated here.
