[0040] The following explains some concepts and / or terms involved in a transmission resource determination method, apparatus, device, and storage medium provided in an embodiment of the present application.

[0041] 1. Classification and characteristics of A-IoT devices in 3GPP

[0042] The 3GPP R19 A-IoT study characterizes ambient IoT devices based on their energy storage capacity and their ability to generate radio frequency signals for transmission. The A-IoT device has one of the following energy storage capabilities:

[0043] Storage capacity 1: No ability to store energy;

[0044] Storage capacity 2: Energy can be stored up to E1 or E2 joules, where E1 = E2;

[0045] Storage capacity3: Energy can be stored up to E2 joules.

[0046] Depending on these storage capacities, the study considered the following set of ambient IoT devices:

[0047] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0048] Device B: has energy storage but no independent signal generation, i.e. backscatter transmission. Utilization of stored energy may include amplification of the reflected signal.

[0049] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0050] Devices with different energy storage capacities also affect their transmission quality. Generally, devices with higher energy storage also have higher receive sensitivity or higher transmit power, which means that the reliability of the receive or transmit link can be better guaranteed.

[0051] 2. A-IoT data / service types

[0052] 3GPP R19A-IoT studies the following data / service types:

[0053] Device-originated (DO);

[0054] Device-terminated (DT);

[0055] DO and DT data represent data flows originating from or being transmitted to A-IoT devices. DO data, which originates from A-IoT devices, can be further categorized as follows:

[0056] A-IoT devices autonomously initiate data transmission (DO-Autonomous, DO-A); for example, connecting a large number of various sensors that collect and actively report information about the environment, devices, and organisms when necessary;

[0057] Base stations and other reader / writer devices trigger A-IoT device-initiated (DO-DTT) data transmissions. For example, asset identification, status reporting, and tracking are all downlink-triggered reports. Read / write devices collect data from tags by triggering inventory procedures. Because the data is generated / initiated by the A-IoT device, this service should be considered a DO service initiated by a tag, triggered by a control command from the reader / writer side.

[0058] 3. Different A-IoT signal generation methods

[0059] 1) On-Off Keying (OOK)

[0060] There are two ways to generate OOK modulation: one is a multi-carrier OOK signal based on an Orthogonal Frequency Division Multiplexing (OFDM) architecture, and the other is a single-carrier OOK signal.

[0061] The design of multi-carrier OOK signals based on the OFDM architecture aims to preserve the existing base station's transmission architecture. Therefore, appropriate data is sent on the OFDM subcarriers to create a square wave signal in the time domain. Multi-carrier OOK signals based on the OFDM architecture can be categorized into the following four types:

[0062] OOK-1: OOK-1 mainly uses one OFDM symbol to carry one bit of information. When transmitting bit 1, data is transmitted in the frequency domain of the corresponding symbol. When transmitting bit 0, nothing is transmitted in the frequency domain of the corresponding symbol. To increase the transmission rate, it is necessary to increase the subcarrier spacing (SCS). The data in the frequency domain can be a ZC (Zadoff-Chu) sequence, a quadrature amplitude modulation (QAM) signal, etc. to ensure the flatness of the frequency domain signal. Assuming that power pooling is not performed between symbols, nothing is sent in the OFDM where no bit is transmitted, which will result in a certain power loss.

[0063] OOK-2: The OOK-2 waveform is somewhat similar to frequency shift keying (FSK). It primarily divides the frequency domain into multiple bands, each carrying a single bit. When bit 1 is transmitted, data is transmitted on the corresponding band; when bit 0 is transmitted, nothing is transmitted on the corresponding band. Frequency domain data can be ZC sequences, QAM signals, or other methods to ensure frequency domain signal flatness. If power pooling within a symbol is not performed, no data is transmitted on bands where no bits are transmitted, resulting in a certain amount of power loss.

[0064] OOK-3: OOK-3 divides the frequency domain into multiple bands. Some subcarriers (tones) in each band are modulated. The receiver extracts and demodulates the corresponding subcarriers through the receiver.

[0065] OOK-4: The OOK-4 waveform is one of the more flexible waveforms, capable of controlling the transmission rate by adjusting the number of bits transmitted within an OFDM symbol. OOK-4 can be generated using two methods: Discrete Fourier Transform-Spread OFDM (DFT-S-OFDM) and the least squares method (LS). The idea behind DFT-S-OFDM is to first generate the desired waveform in the time domain, where the number of sampling points equals the number of resource elements (REs) in the wake-up signal (WUS) bandwidth. The frequency domain information is then obtained through the DFT. The least squares method also uses the desired time domain waveform to infer the frequency domain waveform. It primarily optimizes the input frequency domain sequence X using the Fast Fourier Transform (FFT) matrix and the ideal time domain waveform.

[0066] OOK-5: This pulse-shaped OOK waveform can also be generated using non-OFDM transmission structures. It generates a pulse signal and modulates it through a spectrum shaping filter to produce an on signal. When the signal is not transmitted, it becomes an off signal. This method simplifies OOK signal generation, and the spectrum shaping filter reduces signal leakage to adjacent frequencies.

[0067] 2) Offset-Quadrature Phase Shift Keying (O-QPSK) or Differential Binary Phase Shift Keying (DBPSK)

[0068] Active tags can use offset O-QPSK or DBPSK modulation to send data. These two modulation methods belong to constant envelope modulation technology.

[0069] The O-QPSK modulation process can be described as follows: the serial input binary data stream is split into two different transmission paths, the I path and the Q path. The "I" component is used to synchronize with the data waveform, and the "Q" component is used to be "orthogonal" to the data waveform. That is, the even-numbered bits of the original input data are assigned to the I path, and the odd-numbered bits are assigned to the Q path. The in-phase and quadrature paths are staggered by half a symbol period. The I and Q paths are then used to modulate the carrier, using one of four discrete phase variations to represent each symbol (a bit pair).

[0070] BPSK and QPSK are similar in that they both use phase to carry symbol information. For example, when the input code element is a "1," the baseband modulator outputs a 1 (phase 0 degrees); when the input code element is a "0," the baseband modulator outputs a -1 (phase 0 degrees). However, BPSK suffers from phase ambiguity. Phase ambiguity occurs when the recovered digital information changes from a "0" to a "1" or vice versa, resulting in erroneous recovery. This phenomenon, caused by the phase inversion of the local reference carrier and resulting in erroneous recovery in the receiving system, is called "phase ambiguity." To address this issue, differential coding was introduced, enabling decoding at the receiving end to be based on phase changes rather than absolute phase values. This is known as DBPSK. To achieve better link performance and interference mitigation, the original bit information is expanded using spreading sequences and / or coding.

[0071] 3) Minimum Shift Keying (MSK) and Gaussian Filtered Minimum Shift Keying (GMSK) modulation

[0072] MSK is a constant envelope continuous phase modulation, a modulation method developed from FSK modulation. In FSK, the carrier frequency changes randomly with the modulating signal, which is usually "0" or "1", and the phase after modulation is discontinuous. If the phase is continuous, it is called continuous phase frequency shift keying (CP-FSK). The so-called MSK modulation method is a special form of CP-FSK with a modulation index of 0.5. The MSK modulation principle is as follows:

[0073] Among them, , where θ k The additional phase function is used to ensure the phase continuity between different symbols, ω c t is the carrier angular frequency, T s is the code element width; a k is the phase constant of the kth symbol.

[0074] Because MSK's phase path is a curve, and its power spectrum sidelobes, as observed on a spectrum analyzer, deviate from the center frequency, resulting in slower attenuation, a Gaussian filter is added before MSK modulation to compensate for these shortcomings and improve attenuation performance. This modulator is therefore called GMSK.

[0075] GMSK modulation is to add a Gaussian low-pass filter before the MSK modulator, which makes the signal smoother and significantly improves the sidelobe attenuation performance of the power spectrum. After MSK modulation, the symbol data, namely the I and Q channels, are output. The final GMSK expression is as follows:

[0076] Where A represents the signal envelope, ω c represents the carrier angular frequency, Represents the information phase.

[0077] The following describes in detail the transmission resource determination method provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0078] The embodiment of the present application provides a method for determining transmission resources, and Figure 2 shows a flow chart of the method for determining transmission resources provided by the embodiment of the present application. As shown in Figure 2, the method for determining transmission resources provided by the embodiment of the present application may include the following step 201.

[0079] Step 201: The first device determines a first resource according to first information.

[0080] In the embodiment of the present application, the first resource is a transmitting frequency domain resource or a receiving frequency domain resource of the first device. The first information includes at least one of the following:

[0081] Type of transmitted signal;

[0082] Type of transmission service or data size;

[0083] At least one of a type, capability information, and a signal reception measurement value of the first device.

[0084] In an embodiment of the present application, the above-mentioned first device is a response device. Optionally, the response device can be a tag, that is, an electronic tag, such as a radio frequency identification (RFID) tag. Among them, radio frequency identification technology can be divided into three types: active, passive and semi-active. Passive tags can also be called passive IOT, that is, passive Internet of Things devices. The communication method of the response device can be backscatter (RF) signal transmission, or some active tags have the ability to actively generate signals. Because the energy of the response device can come from the environment, such as ambient RF energy, thermal energy, wind energy, kinetic energy, etc., the response device can also be called Ambient IoT (i.e. A-IoT). A response device with a battery can also be regarded as a terminal, or a terminal device.

[0085] Optionally, in an embodiment of the present application, the first information includes a type of a transmission signal (or channel). The transmission signal is a first signal, and the first resource is a first frequency domain resource; or the transmission signal is a signal other than the first signal, and the first resource is a second frequency domain resource.

[0086] The first signal is one of the following: a synchronization signal, a broadcast channel, a system message, a paging message, a random access signal, a signal of uplink transmission or uplink retransmission scheduled in response to random access, and a hybrid automatic repeat request (HARQ) feedback signal of contention resolution information.

[0087] Optionally, in an embodiment of the present application, the above-mentioned first signal is a received signal, the above-mentioned first resource is a receiving frequency domain resource of the first device, and the received signal is one of the following: a synchronization signal, a broadcast channel, a system message, and a paging message.

[0088] Optionally, in an embodiment of the present application, the above-mentioned first signal is a transmission signal, the above-mentioned first resource is a transmission frequency domain resource of the first device, and the transmission signal is one of the following: a random access signal, a random access response scheduled uplink transmission or uplink retransmission signal, and a HARQ feedback signal of contention resolution information.

[0089] It can be understood that if the received signal is a synchronization signal, a broadcast channel, a system message or a paging message, it is received on the first downlink frequency domain resource; if the received signal is not one of these signals, it is received on the second downlink frequency domain resource.

[0090] If the transmitted signal is a random access signal (such as Msg1 or MsgA), a random access response scheduled uplink transmission or uplink retransmission signal (such as Msg3), or a HARQ feedback signal of contention resolution information, it is sent on the first uplink frequency domain resource; if the transmitted signal is not these signals, it is received on the second uplink frequency domain resource.

[0091] It should be noted that in the embodiment of the present application, the transmission of the response device (first device) and the reception of the read / write device are uplink; the transmission of the read / write device and the reception of the response device (first device) are downlink. The transmission frequency domain resources described in the embodiment of the present application are uplink frequency domain resources, and the reception frequency domain resources are downlink frequency domain resources.

[0092] Exemplarily, for broadcast channels and UE-specific data. The transmission of broadcast channels, system information, and paging information will occupy more resources, resulting in more resources being occupied on the first frequency domain resources. Further transmission of other signals will cause congestion of the frequency domain resources. In order to ensure access delay and coverage, the frequency domain resources for transmission can be determined according to the type of transmission signal, such as synchronization signals, broadcast channels, system information, and other downlink UE-specific data are transmitted on different frequency domain resources. On the first frequency domain resources, the reading and writing device sends at least one of the synchronization signals, broadcast channels, system information, and paging information, and other downlink UE-specific data are transmitted on the second frequency domain resources. In this way, the reading and writing device sends broadcast channels, system information, and paging information on the first frequency domain resources, and sends other signals on the second frequency domain resources; the first device receives broadcast channels, system information, and paging information on the first frequency domain resources, and receives other signals on the second frequency domain resources.

[0093] As another example, uplink transmission related to random access will occupy more resources, resulting in more resources being occupied on the first uplink frequency domain resource. If further transmission of other signals causes congestion of the frequency domain resource. Then the frequency domain resource for transmission can be determined according to the type of transmission signal, for example, the HARQ-acknowledgement (ACK) of Msg1, MsgA, Msg3, MSGB or Msg4 in the random access process and other uplink transmissions are transmitted on different frequency domain resources. On the first frequency domain resource, the first device sends at least one of the HARQ-ACKs of Msg1, MsgA, Msg3, MSGB or Msg4, and the read / write device sends other data on the second frequency domain resource. In this way, the first device sends the HARQ-ACK of Msg1, MsgA, Msg3, MSGB or Msg4 on the first frequency domain resources, and sends other signals on the second frequency domain resources; the reading and writing device receives the HARQ-ACK of Msg1, MsgA, Msg3, MSGB or Msg4 on the first frequency domain resources, and receives other signals sent by the first device on the second frequency domain resources.

[0094] Optionally, in an embodiment of the present application, from a network deployment perspective, downlink and uplink signals transmitted in the idle state need to ensure transmission performance for users with the worst coverage, requiring the reservation of more resources. In this case, the resources reserved for connected state transmission will be relatively limited. Dedicated frequency domain resources can be allocated to uplink or downlink transmissions in the idle state, while other frequency domain resources can be allocated to dedicated transmissions in the connected state to prevent conflicts between idle state transmission resources and connected state transmission resources. This can reduce the latency of uplink or downlink signals transmitted in the connected state.

[0095] Optionally, in an embodiment of the present application, the first information includes a type of transmission service, and the first resource is a transmission frequency domain resource of the first device. Alternatively, the transmission service is a transmission indicated by a control command, and the first resource is a first frequency domain resource; or alternatively, the transmission service is a transmission initiated by the first device, and the first resource is a second frequency domain resource.

[0096] It can be understood that if the type of transmission service is transmission indicated by a control command, it is transmitted on the first uplink frequency domain resource, such as dynamic grant transmission; if the type of transmission service is transmission actively initiated by the first device, it is transmitted on the second uplink frequency domain resource, such as configured grant transmission.

[0097] For example, the transmission resources for configuration authorization are usually pre-configured resources, and the network (read-write device) needs to avoid configuration authorization resources to further perform dynamic authorization uplink transmission. In order to reduce the impact of configuration authorization resource configuration on dynamic authorization uplink transmission resources, the frequency domain resources for the two transmissions can be separated, for example, configuration authorization uplink transmission and dynamic authorization uplink transmission are transmitted on different frequency domain resources. The first device sends a configuration authorization on the first frequency domain resource; the first device sends a dynamic authorization on the second frequency domain resource; the read-write device configures / instructs the configuration authorization transmission and receives the configuration authorization on the first frequency domain resource, and schedules and receives the dynamic authorization sent by the first device on the second frequency domain resource. In this way, by adopting the above-mentioned resource division method, the network can simplify the complexity of resource scheduling and receiving processing, reduce the impact of configuration authorization on dynamic authorization transmission resources, and reduce the delay caused by conflicts between different services.

[0098] Optionally, in an embodiment of the present application, the configuration authorization corresponds to the DO-DOA service type, and the dynamic authorization corresponds to the DO-DTT service type. These two service types can be considered to be allocated to different frequency domain resources for transmission. These two service types can also be supported using small data transmission (SDT). Specifically, DO-DOA / configuration authorization can correspond to MO (or DO)-SDT transmission, and dynamic authorization / DO-DTT can correspond to MT (or DT)-SDT transmission.

[0099] Optionally, in an embodiment of the present application, the first information includes a type of transmission service, and the first resource is a transmission frequency domain resource of the first device. Alternatively, the transmission service is aperiodic transmission, and the first resource is a first frequency domain resource; or alternatively, the transmission service is periodic transmission, and the first resource is a second frequency domain resource.

[0100] It can be understood that the above-described configuration authorization and dynamic authorization schemes can be understood as determining transmission resources based on the periodic characteristics of transmission, with aperiodic and periodic transmissions being transmitted on different frequency domain resources. For example, aperiodic transmissions are transmitted on a first frequency domain resource, while periodic transmissions are transmitted on a second frequency domain resource. This can reduce the impact of aperiodic transmissions on periodic transmission resources and reduce the complexity of network scheduling for the two types of resources.

[0101] Optionally, in an embodiment of the present application, the first information includes the data size of the transmission service, and the first resource is a transmission frequency domain resource of the first device. If the data size of the transmission service is greater than or equal to a first threshold, the first resource is a first frequency domain resource; or if the data size of the transmission service is less than the first threshold, the first resource is a second frequency domain resource.

[0102] Optionally, in an embodiment of the present application, the first information includes the data size of the transmission service, and the first resource is a transmission frequency domain resource of the first device. If the data size of the transmission service is greater than a first threshold, the first resource is a first frequency domain resource; alternatively, if the data size of the transmission service is less than or equal to the first threshold, the first resource is a second frequency domain resource.

[0103] Optionally, in an embodiment of the present application, the first information includes the data size of the transmission service, and the first resource is a transmission frequency domain resource of the first device. Alternatively, the data size of the transmission service is fixed, and the first resource is a first frequency domain resource; or alternatively, the data size of the transmission service is variable, and the first resource is a second frequency domain resource.

[0104] It should be noted that whether the data size of a transmission service is fixed or variable depends on the type of transmission service. For example, the data size of periodic data reports (such as identity information, temperature, humidity, and other sensor data, measurement information, etc.) is usually fixed; while the data size of some event-triggered data transmissions or application-triggered data reports with bursty nature is variable.

[0105] Optionally, in an embodiment of the present application, the first information includes the type of the first device. The first device is a device that transmits signals based on backscatter, and the first resource is a first frequency domain resource; or the first device is a device capable of actively sending signals, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is a first uplink frequency domain resource or a first downlink frequency domain resource, and the second frequency domain resource is a second uplink frequency domain resource or a second downlink frequency domain resource.

[0106] As you can understand, Ambient IoT devices have different signal generation methods, including those that actively transmit signals (type-1 devices) and those that transmit signals based on backscatter (type-2 devices). These two types of devices exhibit significant differences in reception sensitivity, signal characteristics, and data rates. To reduce the complexity of network scheduling and signal transmission and reception, different devices can be assigned to different frequency domain resources for transmission.

[0107] If the first device is a type-1 device, which typically consumes higher power but generally has better downlink receive sensitivity, the network can assign the two types of devices to different frequency resources. The type-1 device transmits on the first frequency resource, while the type-2 device transmits on the second frequency resource.

[0108] Type-1 devices have high receiver sensitivity, and the quality of their actively transmitted signals is superior to that of reflected signals. This allows the network to maintain transmission performance with relatively fewer transmission resources, lower transmit power, or less complex receive processing. Type-2 devices, on the other hand, have lower receiver sensitivity and poorer channel quality for backscattered signals. Therefore, the network requires more transmission resources, higher transmit power, or more complex processing to maintain transmission performance. Separating transmission resources in the frequency domain allows the network to allocate resources, power, and processing capacity more efficiently, reducing the complexity of communication between the two types of devices.

[0109] Optionally, in an embodiment of the present application, the above-mentioned first information includes capability information of the first device, and the above-mentioned capability information is used to indicate at least one of the following: supported energy storage capability, supported receiving sensitivity capability, supported transmitting power capability, and supported signal generation mode capability.

[0110] Optionally, in an embodiment of the present application, the capability information is used to indicate energy storage capability. The energy storage supported by the first device is greater than or equal to the second threshold, and the first resource is a first frequency domain resource; or, the energy storage supported by the first device is less than the second threshold, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is a first uplink frequency domain resource or a first downlink frequency domain resource, and the second frequency domain resource is a second uplink frequency domain resource or a second downlink frequency domain resource.

[0111] Optionally, in an embodiment of the present application, the capability information is used to indicate energy storage capability. The energy storage supported by the first device is greater than the second threshold, and the first resource is a first frequency domain resource; or, the energy storage supported by the first device is less than or equal to the second threshold, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is a first uplink frequency domain resource or a first downlink frequency domain resource, and the second frequency domain resource is a second uplink frequency domain resource or a second downlink frequency domain resource.

[0112] It can be understood that for devices with different energy storage capabilities, the different amounts of stored energy will be reflected in communication indicators such as receiving sensitivity and transmitting power. In this case, devices with different energy storage capabilities can also be allocated to different frequency domain resources for transmission to reduce the complexity of network processing.

[0113] Optionally, in an embodiment of the present application, the capability information is used to indicate the receive sensitivity capability. The receive sensitivity supported by the first device is less than a third threshold, and the first resource is a first frequency domain resource; alternatively, the receive sensitivity supported by the first device is greater than or equal to the third threshold, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is a first uplink frequency domain resource or a first downlink frequency domain resource, and the second frequency domain resource is a second uplink frequency domain resource or a second downlink frequency domain resource.

[0114] Optionally, in an embodiment of the present application, the capability information is used to indicate the receive sensitivity capability. The receive sensitivity supported by the first device is less than or equal to a third threshold, and the first resource is a first frequency domain resource; alternatively, the receive sensitivity supported by the first device is greater than the third threshold, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is a first uplink frequency domain resource or a first downlink frequency domain resource, and the second frequency domain resource is a second uplink frequency domain resource or a second downlink frequency domain resource.

[0115] Optionally, in an embodiment of the present application, the capability information is used to indicate the transmit power capability. The transmit power supported by the first device is greater than or equal to the fourth threshold, and the first resource is a first frequency domain resource; or, the transmit power supported by the first device is less than the fourth threshold, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is a first uplink frequency domain resource or a first downlink frequency domain resource, and the second frequency domain resource is a second uplink frequency domain resource or a second downlink frequency domain resource.

[0116] Optionally, in an embodiment of the present application, the capability information is used to indicate transmit power capability. The transmit power supported by the first device is greater than a fourth threshold, and the first resource is a first frequency domain resource; alternatively, the transmit power supported by the first device is less than or equal to the fourth threshold, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is a first uplink frequency domain resource or a first downlink frequency domain resource, and the second frequency domain resource is a second uplink frequency domain resource or a second downlink frequency domain resource.

[0117] It is understood that first devices can be directly classified based on transmit power or receive sensitivity. Alternatively, for first devices with the same active signal transmission capability, sub-classification can also be performed based on transmit power level or receive sensitivity. Different sub-classes of devices can operate in different frequency domains, reducing the complexity of network processing of different sub-classes of devices.

[0118] Optionally, in an embodiment of the present application, the first device can be classified into device types based on the supported transmission bandwidth. Devices with a bandwidth greater than or equal to a threshold value transmit on a first frequency domain resource; devices with a bandwidth less than the threshold value transmit on a second frequency domain resource. In this way, the first frequency domain resource has a larger bandwidth and can transmit at a high rate or high chip rate modulation; the second frequency domain resource has a smaller bandwidth and can transmit at a relatively low rate or low chip rate.

[0119] Optionally, in an embodiment of the present application, devices supporting a bandwidth greater than a threshold value transmit on a first frequency domain resource; and devices supporting a bandwidth less than or equal to the threshold value transmit on a second frequency domain resource.

[0120] Optionally, in an embodiment of the present application, the signal generation method includes at least one of the following: a modulation method, a line code encoding or decoding method, and a channel encoding or decoding method. The first device supports transmission of the first signal generation method, and the first resource is a first frequency domain resource; or, the first device supports transmission of the second signal generation method or does not support transmission of the first signal generation method, and the first resource is a second frequency domain resource. It should be noted that the first frequency domain resource here is the first uplink frequency domain resource or the first downlink frequency domain resource, and the second frequency domain resource is the second uplink frequency domain resource or the second downlink frequency domain resource.

[0121] Optionally, in an embodiment of the present application, if the first device supports transmission (sending or receiving) of the first modulation mode, transmission is performed on the first frequency domain resources; if the first device supports the second modulation mode or does not support transmission of the first modulation mode, transmission is performed on the second frequency domain resources.

[0122] Optionally, in an embodiment of the present application, if the first device supports transmission (sending or receiving) of the first line code, transmission is performed on the first frequency domain resources; if the first device supports the second line code or does not support transmission of the first line code, transmission is performed on the second frequency domain resources.

[0123] Optionally, in an embodiment of the present application, if the first device supports transmission (sending or receiving) of the first channel coding, transmission is performed on the first frequency domain resources; if the first device supports the second channel coding or does not support transmission of the first channel coding, transmission is performed on the second frequency domain resources.

[0124] Optionally, in an embodiment of the present application, the above-mentioned modulation mode may include at least one of the following: GMSK, OOK, Amplitude Shift Keying (ASK), FSK, Binary Phase Shift Keying (BPSK), or Quadrature Phase Shift Keying (QPSK).

[0125] Optionally, in the embodiment of the present application, the OOK may include at least one of the following: OOK-1, OOK-2, OOK-3, OOK-4, and OOK-5. For the explanation of OOK, please refer to the description in the above embodiment, which will not be repeated here.

[0126] Optionally, in an embodiment of the present application, the above-mentioned ASK may include at least one of the following: phase reversal (PR)-ASK, double side band (DSB)-ASK, and single side band (SSB)-ASK.

[0127] Optionally, in an embodiment of the present application, the above-mentioned BPSK may be DBPSK, and the above-mentioned QPSK may be O-QPSK.

[0128] Exemplarily, the first device supporting BPSK transmission transmits (at least one of sending and receiving) with the read-write device on the first frequency domain resources; the first device supporting OOK transmission transmits with the read-write device on the second frequency domain resources.

[0129] Optionally, in an embodiment of the present application, the above-mentioned line code encoding or decoding method may include at least one of the following: Miller code, Bi-Phase Space Coding (FM0) code, Manchester code, and Pulse Interval Encoding (PIE) code.

[0130] Optionally, in an embodiment of the present application, the above-mentioned Miller code may include at least one of the following: Miller-2 code, Miller-4 code, Miller-8 code, etc.

[0131] Optionally, in an embodiment of the present application, the Manchester code may include at least one of the following: Manchester-2 code, Manchester-4 code, etc.

[0132] Optionally, in the embodiment of the present application, the line code encoding or decoding of different devices may be line code encoding or decoding using different numbers of repetitions.

[0133] Exemplarily, a first device supporting Manchester code transmission transmits (at least one of sending and receiving) with a read-write device on a first frequency domain resource, and a first device supporting Miller code or FM0 code transmission transmits with a read-write device on a second frequency domain resource.

[0134] Optionally, in an embodiment of the present application, the above-mentioned channel coding or decoding method may include at least one of the following: convolutional code, turbo code, low density parity check code (LDPC), polar code, Hamming code, reed muller code, repetition coding or decoding.

[0135] Exemplarily, a first device that does not support channel coding or only supports repetition coding transmission transmits (at least one of sending and receiving) with a read-write device on a first frequency domain resource, and a first device that supports channel coding transmission such as convolutional code, turbo code, LDPC code, polar code, Hamming code, or Reed Muller code transmits with a read-write device on a second frequency domain resource.

[0136] It is understandable that different devices may use different signal generation methods (such as modulation or waveform methods, line code encoding or decoding methods, channel encoding or decoding methods). The reasons for this may be different network scheduling or configuration, or because the device itself supports different signal generation methods.

[0137] Different signal generation methods correspond to transmission performance, processing complexity, and mutual interference with other coexisting Radio Access Technologies (RATs) (such as NR and LTE deployments). For transmissions using different modulation or waveform methods, line code encoding or decoding methods, and channel encoding or decoding methods, different devices transmit on different frequency domain resources. This can reduce network scheduling and processing complexity, reduce mutual interference between coexisting RATs, and improve transmission performance between the first device and the reader / writer device.

[0138] Optionally, in an embodiment of the present application, the first information includes a signal reception measurement value of the first device. If the signal reception measurement value is greater than or equal to a fifth threshold, the first resource is a first frequency domain resource; or if the signal reception measurement value is less than the fifth threshold, the first resource is a second frequency domain resource.

[0139] Optionally, in an embodiment of the present application, the first information includes a signal reception measurement value of the first device. If the signal reception measurement value is greater than a fifth threshold, the first resource is a first frequency domain resource; or if the signal reception measurement value is less than or equal to the fifth threshold, the first resource is a second frequency domain resource.

[0140] Optionally, in an embodiment of the present application, the above-mentioned signal reception measurement value may include at least one of the following: reference signal receiving power (Reference Signal Receiving Power, RSRP), reference signal receiving quality (Reference Signal Receiving Quality, RSRQ), received signal strength indication (Received Signal Strength Indicator, RSSI), and channel quality indication (Channel Quality Indicator, CQI).

[0141] It can be understood that the first device can determine the frequency domain resources according to the size of the received measurement value of the first device. The received measurement value reflects the quality of the channel, which also reflects the reliability of the transmission; then the frequency domain resources can be divided according to the size of the received measurement value. For example, if the received measurement value is greater than or equal to the preset threshold, the transmission is performed on the first frequency domain resource; if the received measurement value is less than the preset threshold, the transmission is performed on the second frequency domain resource. Based on this resource division method, the network can configure or instruct appropriate parameters and devices on different frequency domain resources to communicate. Devices with better channel quality can allocate fewer resources to achieve the target performance; and devices with poor channel quality can allocate more resources to ensure transmission reliability. When the network receives the transmission of the device with the corresponding channel quality, it can make a preliminary judgment on the quality of the channel, and subsequently use appropriate parameters to send downlink to the device with the corresponding channel quality.

[0142] Optionally, in the embodiment of the present application, in combination with FIG. 2 , as shown in FIG. 3 , the above step 201 may be specifically implemented through the following step 201 a.

[0143] Step 201a: The first device determines a first resource from a plurality of frequency domain resources according to the first information, where the plurality of frequency domain resources are predefined or configured by a read / write device.

[0144] Optionally, in an embodiment of the present application, there is a guard interval between the above-mentioned multiple frequency domain resources, and the size of the guard interval is predefined or configured by the read-write device.

[0145] It should be noted that in the embodiments of the present application, the read / write device can be a handheld or fixed device that reads (and sometimes writes) tag information. It can also be understood as a device that communicates with the tag, such as a terminal, a base station, or a device with read / write functions, such as a reader / writer, and the specific embodiments of the present application are not limited thereto. The read / write function refers to reading information from the answering device (receiving information sent by the answering device) or writing information (sending information to the answering device for reception).

[0146] Optionally, in an embodiment of the present application, the frequency domain position of each frequency domain resource in the above-mentioned multiple frequency domain resources can be indicated by a reading and writing device.

[0147] Optionally, in an embodiment of the present application, the frequency domain positions of some of the multiple frequency domain resources are indicated by a reader / writer device, and the frequency domain positions of another portion of the frequency domain resources are determined based on the frequency domain positions of the first portion of the frequency domain resources. For example, the frequency domain positions of one or more second frequency domain resources are determined based on the frequency domain position, bandwidth, gap between frequency domain resources, and the number of first frequency domain resources.

[0148] Optionally, in an embodiment of the present application, the frequency domain position of the first frequency domain resource or the frequency domain position of the second frequency domain resource is determined by one of the following methods:

[0149] Instructed by the read / write device;

[0150] The frequency domain position of another frequency domain resource is determined based on the known frequency domain position of one frequency domain resource. For example, the frequency domain position of the second frequency domain resource is determined based on the frequency domain position and frequency domain offset of the first frequency domain resource.

[0151] Optionally, in an embodiment of the present application, the frequency domain position of the above-mentioned known frequency domain resource can be indicated by a reading and writing device.

[0152] Optionally, in an embodiment of the present application, the frequency domain positions at different times may be the same or different. If the frequency domain positions are different, the frequency domain position of the first frequency domain resource and the frequency domain position of the second frequency domain resource may be determined based on an index of a time unit, such as a time slot, subframe, or radio frame number.

[0153] Optionally, in an embodiment of the present application, the frequency domain resources may be a carrier, a bandwidth part (Bandwidth Part, BWP), a frequency domain region or a sub-band.

[0154] In an embodiment of the present application, for uplink or downlink transmission of A-IoT, multiple frequency domain resources can be allocated for uplink or downlink transmission, so as to improve the capacity of A-IoT and support multiplexed transmission with different characteristics.

[0155] Optionally, in an embodiment of the present application, in combination with FIG. 2 , as shown in FIG. 4 , the above step 201 may be specifically implemented through the following steps 201b and 201c.

[0156] Step 201b: The first device determines N frequency domain resources according to the first information.

[0157] Wherein, N is an integer greater than 1.

[0158] Step 201c: The first device determines a first resource from N frequency domain resources using a first method.

[0159] In the embodiment of the present application, the first method includes one of the following:

[0160] Selecting a frequency domain resource from the N resources according to the identifier of the first device;

[0161] Randomly select a frequency domain resource from N resources;

[0162] The weight factor is determined according to the weight factors of the N frequency domain resources, where the weight factor is configured by the read / write device or determined by the configuration information of the frequency domain resources.

[0163] Optionally, in the embodiments of the present application, the identifiers of different devices correspond to different frequency-domain resources. The frequency-domain resources corresponding to the identifier of each device are predefined or configured by a read / write device.

[0164] Optionally, in the embodiments of the present application, the first device may determine the first resource according to mod(device identifier, N). Where mod(device identifier, N) is a modulo operation. For example, if the value of mod(device identifier, N) is equal to 0, it corresponds to the first frequency-domain resource among N resources. If the value of mod(device identifier, N) is equal to 1, it corresponds to the second frequency-domain resource among N resources.

[0165] Optionally, in the embodiments of the present application, the weight factor of each frequency-domain resource may be predefined or configured by a read / write device.

[0166] Optionally, in the embodiments of the present application, the configuration of each frequency-domain resource implicitly determines the weight factor. For example, for downlink transmission resources, if the frequency-domain resource contains a synchronization signal or a broadcast channel, the weight factor is X. If it does not contain a synchronization signal or a broadcast channel, the weight factor is Y. X and Y may be different. In one example, X < Y, which can reduce the load of the frequency-domain resources that have been used to transmit the synchronization signal or the broadcast channel. <00003得48>

[0167] For another example, for uplink transmission resources, if the frequency-domain resource contains the transmission of a random access signal, the weight factor is X. If it does not contain a random access signal, the weight factor is Y. X and Y may be different. In one example, X < Y, which can reduce the load of the frequency-domain resources that have been used to transmit the random access signal.

[0173] Step 301: The read / write device determines a second resource based on the first information.

[0174] In the embodiment of the present application, the second resource is a sending frequency domain resource or a receiving frequency domain resource of the read / write device. The first information includes at least one of the following:
