  • A-IoT devices have one of the following energy storage capabilities:
  • Storage capacity 1 No ability to store energy
  • Storage capacity3 Energy can be stored up to E2 joules.
  • IoT devices can be divided into three types: device A, device B, and device C, depending on the energy storage capacity of the IoT devices and their ability to generate radio frequency signals for transmission according to the environment:
  • Device B has energy storage, no independent signal generation, i.e. backscatter transmission, the use of stored energy may include amplification of the reflected signal;
  • Device C has energy storage and has independent signal generation, i.e. active RF components for transmission.
  • A-IoT data or service types include the following two types:
  • device-initiated services include device-actively triggered (DO traffic includes DO autonomous, DO-A) services and device-passively triggered (DO device-terminated triggered, DO-DTT) services.
  • DO traffic includes DO autonomous, DO-A
  • DO-DTT device-passively triggered
  • DO data streams originating from A-IoT devices i.e., DO data
  • DO data streams originating from A-IoT devices they can be further classified into the following two categories:
  • DO-A that is, AIoT devices autonomously initiate data transmission, such as connecting a large number of various sensors that collect and actively report information about the environment, equipment, and organisms when necessary;
  • DO-DTT that is, base stations and other reader devices trigger AIoT devices to initiate data transmission, such as asset identification, status reporting and tracking, which are all downlink (DL) trigger reports.
  • Readers collect data from tags by triggering inventory procedures. Since the data is generated or initiated in the Internet of Things (IoT) device, this service should be regarded as a DO service initiated by the tag triggered by the reader-side control command.
  • IoT Internet of Things
  • A-IoT system deployment scenarios can be divided into the following three scenarios:
  • Scenario 1 A-IoT is deployed in the system bandwidth of NR, also known as in-band deployment.
  • the same base station provides services for A-IoT devices and New Radio (NR) UEs; in another implementation, different base stations provide services for A-IoT devices and NR UEs.
  • NR New Radio
  • Scenario 2 A-IoT is deployed in the guard interval of the NR system, also known as guard band deployment.
  • the same base station provides services for A-IoT devices and NR UEs.
  • different base stations provide services for A-IoT devices and NR UEs.
  • Scenario 3 A-IoT is deployed outside the protection interval of the NR system (obviously, not within the NR system bandwidth), also known as stand-alone deployment.
  • the base station usually only provides services for A-IoT devices.
  • OOK On-Off Keying
  • OOK modulation There are two generation methods for OOK modulation: one is a multi-carrier OOK signal (MC-OOK) based on the Orthogonal Frequency Division Multiplexing (OFDM) architecture; the other is a single-carrier OOK signal.
  • MC-OOK multi-carrier OOK signal
  • OFDM Orthogonal Frequency Division Multiplexing
  • the design idea is to not change the transmitting architecture of the existing base station, so appropriate data is sent on the OFDM subcarrier to make it appear as a square wave signal in the time domain.
  • the generation framework is shown in Figure 2. Among them, there are several types of generation methods for multi-carrier OOK signals generated based on the OFDM architecture:
  • the first type OOK-1;
  • OOK-1 is mainly that one OFDM symbol carries one bit of information.
  • bit1 When bit1 is transmitted, data is transmitted in the frequency domain of the corresponding symbol.
  • bit0 When bit0 is transmitted, no data is transmitted in the frequency domain of the corresponding symbol.
  • the data in the frequency domain can be a ZC (Zadoff-Chu) sequence, orthogonal amplitude modulation (Quadrature Amplitude Modulation, QAM) signal, etc. to ensure the flatness of the frequency domain signal. Assuming that power pooling is not performed between symbols, no data is transmitted on the OFDM that does not transmit bits, and there will be a certain power loss.
  • the second type OOK-2;
  • the OOK-2 waveform is similar to the frequency-shift keying (FSK) waveform, which mainly divides the frequency domain into multiple frequency bands (segments), and each segment carries one bit.
  • FSK frequency-shift keying
  • the data in the frequency domain can be a ZC sequence, QAM signal, etc. to ensure the flatness of the frequency domain signal. Assuming that power pooling is not performed within the symbol, no data is transmitted on the segment that does not transmit the bit, and there will be a certain power loss.
  • the third type OOK-3;
  • OOK-3 is divided into multiple segments in the frequency domain, and then some subcarriers (tones) on each segment will be modulated.
  • the receiving end uses a Goertzel receiver to extract and demodulate the corresponding tone.
  • the fourth type OOK-4;
  • the OOK-4 waveform is a more flexible waveform among several waveforms. It can control the transmission rate by adjusting the number of bits transmitted in an OFDM symbol.
  • DFT-S-FDM Discrete Fourier Transform Spreading Orthogonal Frequency Division Multiplexing
  • LS least squares
  • DFT-S-OFDM The idea of DFT-S-OFDM is to first generate the desired waveform in the time domain.
  • the number of sampling points of the time domain waveform is equal to the number of wake-up signal (WUS) bandwidth resource elements (RE), and then obtain the frequency domain information through discrete Fourier transform (DFT).
  • WUS wake-up signal
  • RE bandwidth resource elements
  • the idea of the least squares method is to infer the frequency domain waveform from the desired time domain waveform. It mainly uses the fast Fourier transform (FFT) matrix and the ideal time domain waveform to optimize the input frequency domain sequence X.
  • FFT fast Fourier transform
  • OQPSK Offset Quadrature Phase Shift Keying
  • DBPSK Differential Binary Phase Shift Keying
  • Active tags can use OQPSK or DBPSK modulation to send data. These two modulation methods belong to constant envelope modulation technology. The following is a brief introduction to the two modulation methods.
  • the modulation process of OQPSK can be described as follows: the serial input binary data code stream is divided into two different paths, I and Q, where "I” is used to "synchronize” with the data waveform, and “Q” is the part that is "orthogonal” to the data waveform, that is, the even bits of the original input data are assigned to the I path, and the odd bits are assigned to the Q path, and the code streams of the in-phase and orthogonal branches are staggered by half a symbol period in time.
  • the carrier is modulated with the I and Q data respectively, that is, one of the four discrete phase changes is used to represent a symbol (i.e., a bit pair) to be transmitted.

  • the frequency domain information of the third channel (eg, PDCCH) may include at least one item from D-1 to D-4.
  • the frequency domain starting point position of the second channel or the third channel can be determined by the frequency domain position of the first channel (such as LP-SSB) by frequency domain offset.
  • the frequency domain starting point position of the second channel or the third channel is: the starting point offset of LP-SSB x*freq_space; wherein x is an integer indicated by MIB, and freq_space represents a predefined interval; for example, it is: the working bandwidth of the AIOT device, or the frequency band interval (such as 1RB) divided by the network for the AIOT system, or the subcarrier interval of the AIOT system, the grid interval, or the carrier bandwidth of the AIOT system, or the BWP bandwidth of the AIOT system.
  • Case 1 LP-SSB and the second channel are in one carrier, one BWP or one narrow subband.
  • the frequency domain offset is similar to the raster offset, which assists in correcting the frequency offset error.
  • the first device can determine the position of the second channel based on the frequency domain offset.
  • Case 2 The LP-SSB second channel is not in a carrier, a BWP, or a narrow band. In this case, it is necessary to indicate not only the frequency domain offset within the carrier/BWP/narrow band, but also an offset to indicate the offset of the carrier/BWP/narrow band index.
  • the first device determines the location of the second channel based on these two indications.
  • carriers/BWPs/segments with adjacent indexes may be adjacent or non-adjacent in the frequency domain.
  • the specific location corresponding to each index does not need to be indicated by MIB and can be predefined (for example, if the environmental Internet of Things is deployed in an in-band mode, only physical resource blocks (PRB) that meet certain conditions are allowed to be used as carriers for AIOT).
  • PRB physical resource blocks
  • the frequency domain offset of the third channel relative to LP-SSB is also applicable to the above-mentioned cases 1 and 2.
  • LP-SSB and the second channel are in the same Candidate carrier/BWP/narrow band, and whether LP-SSB and the third channel are in the same Candidate carrier/BWP/narrow band may be related to the deployment mode of the environmental Internet of Things. For example, for in-band deployment, LP-SSB and the second/third channel may be in the same BWP; for stand-alone deployment, further indication of the relationship may be required.
  • the receiver of the first device when the number of frequency bands occupied by the frequency domain of the second channel or the third channel (or the number of segments) is greater than or equal to 2, the receiver of the first device is required to have the ability to simultaneously receive multiple segments and perform demodulation to enhance coverage performance.
  • the corresponding position can be agreed upon by the protocol implementation or indicated by the network side device; for example, when the number of segments is an even number, the position of the segment can be center-aligned, and the frequency domain starting point position in the above item D-1 belongs to the center point; it can be understood that the position of the segment may be start-point aligned in addition to center alignment. In this case, the frequency domain starting point position in the above item D-1 belongs to the starting point.
  • multi-band concurrent reception may be related to the device type (capability), power level, deployment mode of the environmental IoT, etc. in many ways, as described in Items E-1 to E-2 below:
  • Item E-2 From the perspective of environmental IoT deployment modes, for guard band deployment, the bandwidth resources are relatively limited, the PDCCH channel may not have a lot of bandwidth resources, and the number of frequency bands is relatively small. Stand-alone deployment has the most bandwidth resources, and the number of available frequency bands or segments is relatively large.
  • the multiplexing mode of the second channel or the third channel relative to the first channel can be mainly divided into two modes: TDM and FDM.
  • the multiplexing mode may be related to the deployment scenario. For example, for bandwidth-limited deployment and guard band deployment, TDM is preferred. For receivers that do not have the ability to receive multiple frequency bands simultaneously (such as device A or device B mentioned above), TDM is also preferred.
