[0038] Some concepts and / or terms involved in a transmission resource determination method, apparatus, device, and storage medium provided in the embodiments of this application will be explained below.

[0039] 1. Classification and characteristics of A-IoT devices in 3GPP

[0040] In the 3GPP R19 A-IoT research, the ambient Internet of Things devices are characterized according to the energy storage capacity of the ambient Internet of Things devices and the ability to generate radio frequency signals for transmission. The A-IoT device has one of the following energy storage capabilities:

[0041] Storage capacity 1: No ability to store energy;

[0042] Storage capacity 2: Energy can be stored up to E1 or E2 joules, where it is possible that E1 = E2;

[0043] Storage capacity 3: Energy can be stored up to E2 joules.

[0044] Relying on these storage capacities, the following set of ambient Internet of Things devices is considered in this research:

[0045] Device A: No energy storage, no independent signal generation / amplification, i.e., backscatter transmission;

[0046] Device B: It has energy storage and no independent signal generation, i.e., backscatter transmission. The use of the stored energy can include the amplification of the reflected signal;

[0047] Device C: It has energy storage and independent signal generation, i.e., an active radio frequency component for transmission.

[0048] Devices with different energy storage capabilities also affect the transmission quality of the devices. Generally, devices with higher energy storage also mean higher receiving sensitivity or higher transmitting power. That is, the reliability of the receiving or transmitting link can be better guaranteed.

[0049] 2. A-IoT Data / Service Types

[0050] 3GPP R19 A-IoT has studied the following data / service types:

[0051] Device-originated (DO);

[0052] Device-terminated (DT);

[0053] Among them, DO and DT data indicate that the data stream originates from or is transmitted to an A-IoT device. For the data stream that originates from an A-IoT device, i.e., DO data, it can be further classified as:

[0054] Data transmission initiated autonomously by an A-IoT device (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;

[0055] Data transmission initiated by an A-IoT device triggered by a reading / writing device such as a base station (DO Device-Terminated Triggered, DO-DTT); for example, asset identification, status reporting, and tracking are all downlink-triggered reports, and the reading / writing device collects data from the tag by triggering an inventory program. Since the data is generated / originated in the A-IoT device, this service should be regarded as a DO service triggered by a control command on the reading / writing device side to the tag.

[0056] 3. Different A-IoT Signal Generation Methods

[0057] 1) On-Off Keying (OOK)

[0058] There are two generation methods for the OOK modulation method: one is a multi-carrier OOK signal based on the Orthogonal Frequency Division Multiplexing (OFDM) architecture, and the other is a single-carrier OOK signal.

[0059] For the multi-carrier OOK signal based on the OFDM architecture, its design idea is not to change the transmitting end architecture of the existing base station. Therefore, appropriate data is sent on the OFDM subcarriers so that it presents a square wave signal in the time domain. The multi-carrier OOK signal based on the OFDM architecture can be divided into the following four types:

[0060] OOK-1: OOK-1 mainly has one OFDM symbol carrying one bit of information. When transmitting bit1, data is transmitted in the frequency domain corresponding to the symbol. When transmitting bit0, nothing is transmitted in the frequency domain corresponding to the symbol. To improve the transmission rate, it is necessary to increase the sub-carrier spacing (SCS). The data in the frequency domain can be Zadoff-Chu (ZC) sequences, Quadrature Amplitude Modulation (QAM) signals, etc. to ensure the flatness of the frequency domain signal. Assuming no power pooling between symbols, nothing is transmitted on the OFDM that does not transmit bits, resulting in a certain power loss;

[0061] OOK-2: The waveform of OOK-2 is somewhat similar to Frequency Shift Keying (FSK). It mainly divides multiple frequency bands in the frequency domain, and each frequency band carries one bit. When transmitting bit1, data is transmitted in the corresponding frequency band. When transmitting bit0, nothing is transmitted in the corresponding frequency band. The data in the frequency domain can be ZC sequences, QAM signals, etc. to ensure the flatness of the frequency domain signal. Assuming no power pooling within the symbol, nothing is transmitted on the frequency band that does not transmit bits, resulting in a certain power loss;

[0062] OOK-3: OOK-3 is divided into multiple frequency bands in the frequency domain, and then some of the sub-carriers (tones) on each frequency band are modulated. The receiver at the receiving end extracts the corresponding sub-carriers and demodulates them;

[0063] OOK-4: The OOK-4 waveform is one of the more flexible waveforms among several waveforms. It can control the transmission rate by adjusting the number of bits transmitted within an OFDM symbol. There are two ways to generate OOK-4. One is to generate it using Discrete Fourier Transform-Spread OFDM (DFT-S-OFDM), and the other is to generate it using the Least Squares (LS) method. The idea of DFT-S-OFDM is to first generate the desired waveform in the time domain. The number of sampling points of this time-domain waveform is equal to the number of Resource Elements (REs) of the Wake Up Signal (WUS) bandwidth resource, and then obtain the frequency-domain information through DFT. The Least Squares method also inversely derives the frequency-domain waveform from the desired time-domain waveform. It mainly optimizes the input frequency-domain sequence X by means of the Fast Fourier Transform (FFT) matrix and the ideal time-domain waveform.

[0064] OOK-5: The OOK waveform based on pulse shaping can also be generated using a non-OFDM transmission structure. The generation method is to generate a pulse signal, and modulate the On signal by passing the pulse signal through a spectral shaping filter. When the signal is not transmitted, it is the OFF signal. The generation method of the OOK signal generated in this way is relatively simple, and the spectral shaping filter can reduce the leakage of the signal to adjacent frequencies.

[0065] 2) Offset-Quadrature Phase Shift Keying (O-QPSK) or Differential Binary Phase Shift Keying (DBPSK)

[0066] For the active tag, offset O-QPSK or DBPSK modulation can be used to transmit data. These two modulation methods belong to the constant envelope modulation technology.

[0067] The modulation process of O-QPSK can be described as follows: The serially input binary data stream is divided into two different paths for transmission, namely the I path and the Q path. Among them, "I" is the component used to "synchronize" with the data waveform, and "Q" is the part "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 it is ensured that the code streams of the in-phase and quadrature branches are staggered by half a symbol period in time. Then, the carrier is modulated with the data of the I path and the Q path respectively, that is, one of the 4 discrete phase changes is used to represent a symbol (a pair of bits) to be transmitted.

[0068] BPSK and QPSK are similar in that they both use phase to carry symbol information. For example, when the input symbol is "1", the output of the baseband modulator is 1 (phase 0 degrees); when the input symbol is "0", the output of the baseband modulator is -1 (phase 180 degrees). However, BPSK has a phase ambiguity problem. Phase ambiguity means that the recovered digital information may change from "0" to "1" or from "1" to "0", resulting in incorrect recovery. This phenomenon of incorrect recovery in the receiving system due to the inversion of the local reference carrier is called the "phase ambiguity" phenomenon. To solve this problem, differential coding is introduced, so that the decoding at the receiving end is based on the change in phase rather than the absolute value of the phase. This is DBPSK. To obtain better link performance and anti-interference performance, the original bit information is extended by using spreading sequences and / or coding, etc.

[0069] 3) Minimum Shift Keying (MSK) and Gaussian Filtered Minimum Shift Keying (GMSK) modulation

[0070] MSK is a constant envelope continuous phase modulation, and its modulation method is developed from FSK modulation. In FSK, the carrier frequency changes randomly with the modulation signal. The modulation signal 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, and its modulation index is 0.5. The MSK modulation principle is as follows:

[0071]

[0072] where, let where, θ k is called the additional phase function to ensure the phase continuity between different symbols, ω c t is the carrier angular frequency, T s is the symbol width; a k is the phase constant of the k-th symbol.

[0073] Since the phase path of MSK is a curve and its power spectral sidelobes are observed to deviate from the center frequency on the spectrum analyzer and the attenuation is slow. Therefore, a Gaussian filter is added before MSK modulation to make up for the shortcomings of MSK, so as to achieve the purpose of improving the attenuation performance. Therefore, this modulator is called GMSK.

[0074] GMSK modulation is to add a Gaussian low-pass filter in front of the MSK modulator, so that the signal is smoother and the side lobe attenuation performance of the power spectrum is significantly improved. After MSK modulation, symbol data, namely the I-channel and Q-channel, are output, and finally the GMSK expression is as follows:

[0075]

[0076] Among them, A represents the signal envelope, ω c represents the carrier angular frequency, and

[0077] represents the information phase.

[0078] The embodiments of the present application provide a method for determining transmission resources. Figure 2 The flowchart of the method for determining transmission resources provided by the embodiments of the present application is shown. As Figure 2 shown, the method for determining transmission resources provided by the embodiments of the present application may include the following step 201.

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

[0080] In the embodiments of the present application, the above-mentioned first resource is the transmission frequency domain resource or the reception frequency domain resource of the first device. The above-mentioned first information includes at least one of the following:

[0081] The type of the transmission signal;

[0082] The type or data size of the transmission service;

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

[0084] In the embodiments of the present application, the above-mentioned first device is a response device. Optionally, the response device may be a tag, that is, an electronic tag, such as a Radio Frequency Identification (RFID) tag. Among them, the radio frequency identification technology can be divided into three types: active, passive and semi-active. For passive tags, they can also be called passive IOT, that is, passive Internet of Things devices. The communication method of the response device may be to transmit signals through backscattered (RF) signals, or some active tags have the ability to generate active signals. Since the energy of the response device can come from the environment, such as environmental RF energy, thermal energy, wind energy, kinetic energy, etc., the response device can also be called Ambient IoT (i.e., A-IoT). For response devices with batteries, they can also be regarded as a kind of terminal, and can also be called terminal devices.

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

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

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

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

[0089] It can be understood that if the received signal is a synchronization signal, broadcast channel, system message or paging message, it is received on the first downlink frequency domain resource; if the received signal is not 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), uplink transmission or uplink retransmission signal scheduled by random access response (such as Msg3), or HARQ feedback signal for contention resolution information, it is transmitted 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 embodiments of the present application, the response device (the first device) sending and the reading and writing device receiving are uplink; the reading and writing device sending and the response device (the first device) receiving are downlink. The transmitted frequency domain resource described in the embodiments of the present application is the uplink frequency domain resource, and the received frequency domain resource is the downlink frequency domain resource.

[0092] Exemplarily, for broadcast channels and UE-specific data. The transmission of broadcast channels, system information, and paging information occupies a relatively large amount of resources, resulting in a relatively large amount of resources being occupied in the first frequency domain resource. If other signals are further transmitted, it will cause congestion in this frequency domain resource. To ensure access latency and coverage, the frequency domain resources for transmission can be determined according to the type of transmitted signal. For example, synchronization signals, broadcast channels, system information, and other downlink UE-specific data are transmitted on different frequency domain resources. The reading and writing device transmits at least one of synchronization signals, broadcast channels, system information, and paging information on the first frequency domain resource, and other downlink UE-specific data is transmitted on the second frequency domain resource. In this way, the reading and writing device transmits broadcast channels, system information, and paging information on the first frequency domain resource and other signals on the second frequency domain resource; the first device receives broadcast channels, system information, and paging information on the first frequency domain resource and other signals on the second frequency domain resource.

[0093] Also exemplarily, the uplink transmission related to random access occupies a relatively large amount of resources, resulting in a relatively large amount of resources being occupied in the first uplink frequency domain resource. If other signals are further transmitted, it will cause congestion in this frequency domain resource. Then, the frequency domain resources for transmission can be determined according to the type of transmitted signal. For example, the HARQ-acknowledgment (ACK) of Msg1, MsgA, Msg3, MSGB, or Msg4 during the random access process, and other uplink transmissions are transmitted on different frequency domain resources. The first device transmits at least one of the HARQ-ACKs of Msg1, MsgA, Msg3, MSGB, or Msg4 on the first frequency domain resource, and the reading and writing device transmits other data on the second frequency domain resource. In this way, the first device transmits the HARQ-ACK of Msg1, MsgA, Msg3, MSGB, or Msg4 on the first frequency domain resource and other signals on the second frequency domain resource; the reading and writing device receives the HARQ-ACK of Msg1, MsgA, Msg3, MSGB, or Msg4 on the first frequency domain resource and other signals transmitted by the first device on the second frequency domain resource.

[0094] Optionally, in the embodiments of the present application, from the perspective of network deployment, for the downlink and uplink signals transmitted in the idle state, it is necessary to ensure the transmission performance of the user with the worst coverage, and relatively more resources need to be reserved. In this case, the resources left for connected state transmission will be relatively limited. Exclusive frequency domain resources can be allocated for the uplink or downlink transmission in the idle state, and other frequency domain resources can be allocated for the exclusive transmission in the connected state to prevent conflicts between the idle state transmission resources and the connected state transmission resources. The latency of the uplink or downlink signals in the connected state transmission can be reduced.

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

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

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

[0098] Optionally, in the embodiments of the present application, the above configured grant corresponds to the DO-DOA service type, and the above dynamic grant corresponds to the DO-DTT service type. It can be considered that these two service types are allocated to different frequency domain resources for transmission. These two service types can also be supported by the small data transmission (SDT) method. Specifically, the DO-DOA / configured grant can correspond to the transmission of MO (or DO)-SDT, and the dynamic grant / DO-DTT can correspond to the transmission of MT (or DT)-SDT.

[0099] Optionally, in the embodiments of the present application, the above first information includes the type of the transmission service, and the above first resource is the transmission frequency domain resource of the first device. The above transmission service is non-periodic transmission, and the above first resource is the first frequency domain resource; or, the above transmission service is periodic transmission, and the above first resource is the second frequency domain resource.

[0100] It can be understood that the above-mentioned solutions for configured authorization and dynamic authorization can be understood as determining transmission resources according to the periodic characteristics of transmission. Aperiodic transmission and periodic transmission are transmitted on different frequency-domain resources. For example, aperiodic transmission is transmitted on the first frequency-domain resource, and periodic transmission is transmitted on the second frequency-domain resource. On the one hand, it can reduce the impact of aperiodic transmission on periodic transmission resources, and it can also reduce the complexity of network scheduling for the two types of resources.

[0101] Optionally, in the embodiments of the present application, the above first information includes the data size of the transmission service, and the above first resource is the transmission frequency-domain resource of the first device. The data size of the above transmission service is greater than or equal to the first threshold, and the above first resource is the first frequency-domain resource; or, the data size of the above transmission service is less than the first threshold, and the above first resource is the second frequency-domain resource.

[0102] Optionally, in the embodiments of the present application, the above first information includes the data size of the transmission service, and the above first resource is the transmission frequency-domain resource of the first device. The data size of the above transmission service is greater than the first threshold, and the above first resource is the first frequency-domain resource; or, the data size of the above transmission service is less than or equal to the first threshold, and the above first resource is the second frequency-domain resource.

[0103] Optionally, in the embodiments of the present application, the above first information includes the data size of the transmission service, and the above first resource is the transmission frequency-domain resource of the first device. The data size of the above transmission service is determined, and the above first resource is the first frequency-domain resource; or, the data size of the above transmission service is variable, and the above first resource is the second frequency-domain resource.

[0104] It should be noted that whether the data size of the transmission service is determined or variable is determined by the type of the transmission service. For example, for periodic data reporting (such as sensing data such as identity information, temperature, and humidity, measurement information, etc.), the data size is usually determined; while for example, some event-triggered data transmissions or application-triggered data reports have a burst nature, and the data size is variable.

[0105] Optionally, in the embodiments of the present application, the above first information includes the type of the first device. The above first device is a device that transmits signals based on backscattering, and the above first resource is the first frequency-domain resource; or, the above first device is a device with the ability to actively transmit signals, and the above first resource is the 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.

[0106] It can be understood that Ambient IoT devices have different signal generation methods, including devices that actively send signals (type-1 devices) and devices that transmit signals based on backscattering (type-2 devices). There are significant differences in the receiving sensitivity, signal characteristics, rate, etc. of the two types of devices. To reduce the complexity of network scheduling and signal transceiver processing, different devices can be assigned to different frequency domain resources for transmission.

[0107] If the type of the first device is a type-1 device, then the power consumption of this type of device is also relatively high, and generally the downlink receiving sensitivity is also better; if the type of the first device is a type-2 device, generally the power consumption is relatively low, and the downlink receiving sensitivity is also poor. Then the network can assign the two types of devices to different frequency domain resources. The first device of type-1 transmits on the first frequency domain resource, and the first device of type-2 transmits on the second frequency domain resource.

[0108] For type-1 devices, the receiving sensitivity is high, and the quality of the actively sent signal is better than that of the signal generated by reflection. In this way, the network can ensure the transmission performance with relatively fewer transmission resources, or lower transmission power, or lower complexity of receiving processing; while for type-2 devices, the receiving sensitivity is poor, and the channel quality of the backscattered signal is also poor. Then the network needs to use more transmission resources, or higher transmission power, or higher processing complexity to ensure the transmission performance. Separating the transmission resources in the frequency domain can enable the network to reasonably allocate resources, power, and processing capabilities, and reduce the communication complexity between the two types of devices.

[0109] Optionally, in the embodiments of the present application, the above first information includes the capability information of the first device, and the capability information is used to indicate at least one of the following: supported energy storage capability, supported receiving sensitivity capability, supported transmission power capability, supported signal generation method capability.

The energy storage supported by the first device is greater than or equal to the second threshold, and the above first resource is the first frequency domain resource; or, the energy storage supported by the first device is less than the second threshold, and the above first resource is the 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.

[0111] Optionally, in the embodiments of the present application, the above capability information is used to indicate the energy storage capability. If the energy storage supported by the first device is greater than a second threshold, the above first resource is a first frequency domain resource; or, if the energy storage supported by the first device is less than or equal to the second threshold, the above 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, since the stored energy is different, it will be reflected in communication metrics such as receiving sensitivity and transmission power. In this case, devices with different energy storage capabilities can also be assigned to different frequency domain resources for transmission to reduce the complexity of network processing.

[0113] Optionally, in the embodiments of the present application, the above capability information is used to indicate the receiving sensitivity capability. If the receiving sensitivity supported by the first device is less than a third threshold, the above first resource is a first frequency domain resource; or, if the receiving sensitivity supported by the first device is greater than or equal to the third threshold, the above 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 the embodiments of the present application, the above capability information is used to indicate the receiving sensitivity capability. If the receiving sensitivity supported by the first device is less than or equal to a third threshold, the above first resource is a first frequency domain resource; or, if the receiving sensitivity supported by the first device is greater than the third threshold, the above 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 the embodiments of the present application, the above capability information is used to indicate the transmission power capability. If the transmission power supported by the first device is greater than or equal to a fourth threshold, the above first resource is a first frequency domain resource; or, if the transmission power supported by the first device is less than the fourth threshold, the above 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 the embodiments of the present application, the above capability information is used to indicate the transmission power capability. If the transmission power supported by the first device is greater than the fourth threshold, the first resource is the first frequency domain resource; or, if the transmission power supported by the first device is less than or equal to the fourth threshold, the first resource is the 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.

[0117] It can be understood that the first device can directly classify the device type according to the transmission power magnitude or reception sensitivity, etc.; or, for the first devices that all have the active signal transmission capability, the sub-types can also be classified according to the level of transmission power or the level of reception sensitivity. Different sub-type devices can operate in different frequency domains, reducing the complexity of the network in processing different sub-type devices.

[0118] Optionally, in the embodiments of the present application, the first device can classify the device type from the perspective of the supported transmission bandwidth. Devices with a supported bandwidth greater than or equal to the threshold value transmit on the first frequency domain resource; devices with a supported bandwidth less than the threshold value transmit on the second frequency domain resource. In this way, the first frequency domain resource has a larger bandwidth and can perform high-rate, high-chip-rate modulation transmissions; the second frequency domain resource has a smaller bandwidth and performs relatively low-rate or low-chip-rate transmissions.

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

[0120] Optionally, in the embodiments of the present application, the above signal generation method includes at least one of the following: modulation method, line code encoding or decoding method, channel encoding or decoding method. If the first device supports the transmission of the first signal generation method, the first resource is the first frequency domain resource; or, if the first device supports the transmission of the second signal generation method or does not support the transmission of the first signal generation method, the first resource is the 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 the embodiments of the present application, if the first device supports the transmission (transmission or reception) of the first modulation method, it transmits on the first frequency domain resource; if the first device supports the second modulation method or does not support the transmission of the first modulation method, it transmits on the second frequency domain resource.

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

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

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

[0125] Optionally, in the embodiments of the present application, the above OOK may include at least one of the following: OOK-1, OOK-2, OOK-3, OOK-4, OOK-5. For the explanation of OOK, refer to the description in the above embodiments, and details are not described herein again.

[0126] Optionally, in the embodiments of the present application, the above ASK may include at least one of the following: Phase Reverse (PR)-ASK, Double Side Band (DSB)-ASK, Single Side Band (SSB)-ASK.

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

[0128] Exemplarily, a first device supporting BPSK transmission performs transmission (at least one of sending and receiving) with a reading and writing device on the first frequency domain resource; a first device supporting OOK transmission performs transmission with the reading and writing device on the second frequency domain resource.

[0129] Optionally, in the embodiments of the present application, the above line code encoding or decoding methods may include at least one of the following: Miller code, Bi-Phase Space Coding, Manchester code, Pulse interval encoding (PIE) code.

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

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

[0132] Optionally, in the embodiments of the present application, the line code encoding or decoding of different devices may be line code encoding or decoding with different repetition times.

[0133] Exemplarily, a first device that supports the transmission of Manchester code performs transmission (at least one of sending and receiving) with a reading and writing device on a first frequency domain resource, and a first device that supports the transmission of Miller code or FM0 code performs transmission with the reading and writing device on a second frequency domain resource.

[0134] Optionally, in the embodiments of the present application, the above channel encoding 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 encoding or decoding.

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

[0136] It can be understood that the signal generation methods applicable to different devices (such as different modulation or waveform methods, line code encoding or decoding methods, channel encoding or decoding methods) may also be different, and the different reasons may be different network scheduling or configurations, or because the signal generation methods supported by the devices themselves are different.

[0137] Different signal generation methods correspond to the transmission performance, processing complexity, and mutual interference with other coexisting radio access technologies (RATs) (such as NR, LTE, etc. deployments). For transmissions using different modulation or waveform methods, line code encoding or decoding methods, channel encoding or decoding methods, different devices transmit on different frequency domain resources, which can reduce the complexity of network scheduling and processing, reduce the mutual interference between coexisting RATs, and improve the transmission performance between the first device and the reading and writing device.

[0138] Optionally, in the embodiments of the present application, the above first information includes the signal reception measurement value of the first device. When the signal reception measurement value is greater than or equal to the fifth threshold, the first resource is the first frequency domain resource; or, when the signal reception measurement value is less than the fifth threshold, the first resource is the second frequency domain resource.

[0139] Optionally, in the embodiments of the present application, the above first information includes the signal reception measurement value of the first device. When the signal reception measurement value is greater than the fifth threshold, the first resource is the first frequency domain resource; or, when the signal reception measurement value is less than or equal to the fifth threshold, the first resource is the second frequency domain resource.

[0140] Optionally, in the embodiments of the present application, the above signal reception measurement value may include at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), Channel Quality Indicator (CQI).

[0141] It can be understood that the first device can determine the frequency-domain resources according to the magnitude of the received measurement values of the first device. The received measurement values reflect the quality of the channel, which in turn reflects the reliability of the transmission. Then, the frequency-domain resources can be divided according to the magnitude of the received measurement values. For example, if the received measurement value is greater than or equal to a preset threshold, transmission is performed on the first frequency-domain resources; if the received measurement value is less than the preset threshold, transmission is performed on the second frequency-domain resources. Based on this resource division method, the network can configure or indicate appropriate parameters and devices for communication on different frequency-domain resources. Devices with better channel quality can achieve the target performance by allocating fewer resources, while devices with poorer channel quality can be allocated more resources to ensure transmission reliability. When the network receives the transmission of a device with a corresponding channel quality, it can make a preliminary judgment on the channel quality and then use appropriate parameters to perform downlink transmission to the device with the corresponding channel quality.

[0142] Optionally, in the embodiments of the present application, in combination with Figure 2 , as Figure 3 shown, the above step 201 can be specifically implemented by the following step 201a.

[0143] Step 201a: The first device determines a first resource from multiple frequency-domain resources according to the first information, where the multiple frequency-domain resources are predefined or configured by a reading and writing device.

[0144] Optionally, in the embodiments of the present application, there is a guard interval between the above multiple frequency-domain resources, and the size of the guard interval is predefined or configured by a reading and writing device.

[0145] It should be noted that in the embodiments of the present application, the reading and writing device can be a device for handheld or fixed reading (and sometimes writing) of tag information. It can also be understood as a device communicating with the tag, such as a terminal, a base station, or a device with reading and writing functions, such as a reader. Specifically, the embodiments of the present application do not make any limitations. Among them, the reading and writing function refers to reading information from the response device (receiving the information sent by the response device) or writing information (sending information to the response device for reception).

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

[0147] Optionally, in the embodiments of the present application, the frequency-domain positions of some of the above multiple frequency-domain resources are indicated by the reading and writing device, and the frequency-domain positions of the other part of the frequency-domain resources are determined according to the frequency-domain positions of this part of the frequency-domain resources. For example, according to the frequency-domain position, bandwidth, interval (gap) between frequency-domain resources, and the number of the first frequency-domain resources of the first frequency-domain resource, the frequency-domain positions of one or more second frequency-domain resources are determined.

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

[0149] Indicated by the read-write device;

[0150] Determine the frequency-domain position of another frequency-domain resource according to the frequency-domain position of a known frequency-domain resource. For example, determine the frequency-domain position of the second frequency-domain resource according to the frequency-domain position and frequency-domain offset of the first frequency-domain resource.

[0151] Optionally, in the embodiments of the present application, the frequency-domain position of the above-mentioned known frequency-domain resource can be indicated by the read-write device.

[0152] Optionally, in the embodiments 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 positions of the first frequency-domain resource and the second frequency-domain resource can be determined according to the index of the time unit, such as the slot number, subframe number, or radio frame number.

[0153] Optionally, in the embodiments of the present application, the above-mentioned frequency-domain resource may be a carrier, a bandwidth part (BWP), a frequency-domain region, or a subband.

[0154] In the embodiments of the present application, for the uplink or downlink transmission of A-IoT, multiple frequency-domain resources may be allocated for uplink or downlink transmission to improve the capacity of A-IoT and support multiplexing transmission with different characteristics.

[0155] Optionally, in the embodiments of the present application, in combination with Figure 2 , as Figure 4 shown, the above-mentioned step 201 can be specifically implemented by the following step 201b and step 201c.

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

[0157] Where N is an integer greater than 1.

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

[0159] In the embodiments of the present application, the above-mentioned first method includes one of the following:

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

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

[0162] Determined according to the weight factor of the N frequency-domain resources, and the weight factor is configured by the read-write device or determined by the configuration information of the frequency-domain resource.

[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, and the weight factor for a frequency domain resource that does not contain a synchronization signal or a broadcast channel is Y. X and Y may be different. In one example, X < Y, which can reduce the load on the frequency domain resources that have been used to transmit synchronization signals or broadcast channels.

[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, and the weight factor for a frequency domain resource that does not contain a random access signal is Y. X and Y may be different. In one example, X < Y, which can reduce the load on the frequency domain resources that have been used to transmit random access signals.

The first device may determine the first resource according to the first information, that is, the transmission frequency domain resource or the reception frequency domain resource of the first device. The first information includes at least one of the following: the type of the transmission signal; the type of the transmission service or the data size; at least one of the type, capability information, and signal reception measurement value of the first device.
