[0058] To make the objectives, technical solutions, and advantages of this disclosure more clear, the technical solutions of this disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this disclosure without making any creative efforts shall fall within the scope of protection of this disclosure.

[0059] First, the basic concepts involved in the embodiments of the present disclosure are introduced.

[0060] A-IoT device types: 3GPP divides A-IoT devices into three categories based on whether they have energy storage capabilities and independent signal generation capabilities: device A, device B, and device C.

[0061] Device A: No energy storage capability, no independent signal generation capability, and transmits signals via backscatter.

[0062] Device B: It has energy storage capability but no independent signal generation capability. It transmits signals via backscattering, and the stored energy can be used to amplify the power of the backscattered signal.

[0063] Device C: has energy storage capabilities, the ability to independently generate signals, and uses radio frequency devices for signal transmission.

[0064] Backscatter communication: A backscatter communication system consists of an excitation signal source and a signal reflection device. The excitation signal source may include, for example, a reader, and the signal reflection device may include, for example, a reflective tag. The reader is used to generate the RF excitation signal, and the reflective tag is composed of a device that can reflect the RF signal. The reader sends an RF signal to the reflective tag, which receives the signal sent by the excitation signal source and reflects the RF signal through the reflective tag. By changing the load impedance of the reflective tag antenna, information is modulated into the backscatter signal. When the reflection coefficient is configured to the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured to the second reflection coefficient, the excitation signal is completely reflected; when the reflection coefficient is configured to the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0065] The above embodiments describe the types of A-IoT devices. The following describes possible receiver architectures for A-IoT devices, along with the accompanying figures. For A-IoT devices, the receiver structure is extremely simple and can include, for example, an RF receiver based on on-off keying (OOK), an OOK-based zero-IF receiver, an OOK-based IF receiver, and so on.

[0066] Figure 1 is a schematic diagram of the structure of an OOK-based RF receiver provided by the related art. As shown in Figure 1, the OOK-based RF receiver includes a matching network (Matching network), a radio frequency bandpass filter (Radio Frequency Band-Pass Filter, RF BPF), a radio frequency low noise amplifier (Radio Frequency Low Noise Amplifier, RF LNA), a radio frequency envelope detector (Radio Frequency envelope detector), a baseband amplifier (baseband Amplifier, BB AMP), a baseband low-pass filter (Baseband Low-Pass Filter, BB LPF), an analog-to-digital converter (Analog-to-Digital Converter, ADC), and a digital baseband processor (digital baseband processing).

[0067] Figure 2 shows the structure of an OOK-based zero-IF receiver, as provided in related art. As shown in Figure 2, the OOK-based zero-IF receiver includes, in sequence, a matching network, an RF BPF, an RF LNA, a mixer, a BB AMP, a BB LPF or BPF, an ADC, and a digital baseband processor. The received signal is processed by these components in sequence, with the mixer input also including a local oscillator (LO) signal.

[0068] Figure 3 is a schematic diagram of the structure of an OOK-based IF receiver provided by the related art. As shown in Figure 3, the OOK-based IF receiver includes, in sequence, a matching network, an RF BPF, an RF LNA, a mixer, an IF amplifier (IF AMP), an IF band-pass filter (IF BPF), an IF envelope detector (IF envelope detector), a BB AMP, a BB LPF, an ADC, and a digital baseband processor. The received signal is processed by the above components in sequence, where the mixer input also includes the LO signal.

[0069] As shown in Figures 1 to 3, for A-IoT devices, due to their extremely simple receiver structure, A-IoT devices are unable to complete the reception and processing of the terminal's configuration parameters for random access and paging in the New Radio (NR) system. Specifically, A-IoT devices have the characteristics of low power consumption, low complexity, no power supply or limited power supply. The A-IoT device transmission signal cannot adopt the NR system's time-frequency offset synchronization method, that is, by estimating the time-frequency offset of reference signals such as the synchronization signal block (SSB) and the time-frequency tracking reference signal (TRS). The transmission method of A-IoT devices is very different from that of NR devices. For example, A-IoT devices communicate and transmit through backscattered signals. A-IoT devices cannot actively transmit in the NR system, especially devices of device A and device B. A-IoT devices cannot perform inverse fast Fourier transform (IFFT) operations and do not support orthogonal frequency division multiple access (OFDMA) transmission, especially devices of device A and device B.

[0070] Due to the aforementioned characteristics of A-IoT devices, their transmission methods differ significantly from those of current NR systems. When a large number of A-IoT devices are connected simultaneously, collisions and signal interference between A-IoT devices can occur. Implementing multi-access transmission for A-IoT devices is a pressing technical challenge.

[0071] Based on this, the embodiments of the present disclosure provide a multi-access transmission method to enable parallel transmission of multiple A-IoT devices, thereby improving resource utilization. The following will introduce the solution of the embodiments of the present disclosure with reference to the accompanying drawings.

[0072] FIG4 is a schematic diagram of an applicable application scenario provided by an embodiment of the present disclosure. As shown in FIG4 , the application scenario includes device 41, device 42, device 43, and device 40. Devices 41, 42, and 43 are all A-IoT devices, and device 40 can be any of a network device, a terminal device, and a relay device. In the example of FIG4 , device 40 is described as a network device.

[0073] Device 40 may interact with devices 41, 42, and 43. In the embodiment of the present disclosure, device 40 may send a downlink indication signal to each of devices 41, 42, and 43. The downlink indication signal may be, for example, a query signal for indicating information related to multiple access transmission.

[0074] Device 40 can send an excitation signal to each of device 41, device 42, and device 43. After receiving the excitation signal, the A-IoT device can reflect the signal and send an uplink reflection signal to device 40, for A-IoT devices that do not have the ability to generate signals independently. Taking device 41 and device 42 as an example, if they are devices of type A and device B respectively, then devices 41 and 42 do not have the ability to generate signals independently. Devices 41 and 42 reflect the excitation signal and send their respective uplink reflection signals to device 40. For A-IoT devices that have the ability to generate signals independently, they can generate an uplink transmission signal based on the excitation signal, thereby sending an uplink transmission signal to the network device. Taking device 43 as an example, if it is a device of type C, then device 43 has the ability to generate signals independently. Device 43 generates an uplink transmission signal based on the excitation signal and sends an uplink transmission signal to device 40.

[0075] Based on the example of FIG4 , the solution of the embodiment of the present disclosure is introduced below in combination with FIG5 .

[0076] FIG5 is a flowchart of a multiple access transmission method provided by an embodiment of the present disclosure. The method is applied to a first device. As shown in FIG5 , the method includes:

[0077] S51: Determine, based on first indication information, multiple access reception of a first signal sent by a second device and / or multiple access transmission of a second signal sent to a third device.

[0078] The first device may be, for example, an A-IoT device, the second device may be, for example, any one of a network device, a relay device, and a terminal device, the third device may be, for example, any one of a network device, a relay device, and a terminal device, and the second device and the third device may be the same device or different devices.

[0079] The first device receives a first signal sent by the second device. In some embodiments, the first signal includes one or more of a downlink indication signal, an excitation signal, and a carrier signal. The downlink indication signal is a signal used to carry downlink control information, the excitation signal is a signal used to trigger or carry an uplink signal, and the carrier signal is a carrier signal used to carry an uplink signal. In some embodiments, the excitation signal is a carrier signal.

[0080] In some embodiments, the downlink indication signal includes a first downlink indication signal and / or a second downlink indication signal. The first downlink indication signal and the second downlink indication signal may independently carry the first indication information, or may respectively carry different information in the first indication information.

[0081] The first device transmits a second signal to the third device. In some embodiments, the second signal includes one or more of an uplink reflected signal and an uplink transmitted signal. In some embodiments, if the first device does not have the ability to independently generate a signal, the first device reflects the corresponding signal via backscattering, which is the uplink reflected signal. In some embodiments, if the first device has the ability to independently generate a signal, the first device generates the uplink transmitted signal based on the excitation signal.

[0082] The first device obtains first indication information, where the first indication information is used to indicate relevant information for the first device to perform multiple access transmission.

[0083] In a possible implementation, the first indication information may include one or more of the following:

[0084] 1. Group information, used to indicate the relevant groups in the multi-address sending process or the multi-address receiving process.

[0085] The relevant groups in the multiple-address transmission process or the multiple-address reception process may include signal groups, device groups, and the corresponding relationships between the groups.

[0086] Specifically, the grouping information may include one or more of the following items 1.1 to 1.3:

[0087] 1.1. Signal grouping information, used to indicate the signal grouping of at least one signal and / or the correspondence between signal groups of different signals in at least one signal, the signal grouping of at least one signal including: the signal grouping of the first signal and / or the signal grouping of the second signal.

[0088] At least one signal may include a first signal. Accordingly, a signal group of at least one signal may include a signal group of the first signal. The first signal includes one or more of a downlink indication signal, an excitation signal, and a carrier signal. Therefore, the signal group of at least one signal may include one or more of a downlink indication signal group, an excitation signal group, and a carrier signal group. The downlink indication signal may include one or more of a first downlink indication signal, a second downlink indication signal, and a third downlink indication signal. Therefore, the downlink indication signal group includes a first downlink indication signal group, a second downlink indication signal group, and a third downlink indication signal group.

[0089] At least one signal may include a second signal. Accordingly, a signal grouping of the at least one signal may include a signal grouping of the second signal. The second signal includes one or more of an uplink reflected signal and an uplink transmitted signal. Therefore, the signal grouping of the at least one signal may include an uplink reflected signal grouping and / or an uplink transmitted signal grouping. The first device may determine a signal grouping of the first signal and / or a signal grouping of the second signal based on the signal grouping information.

[0090] The correspondence between signal groups of different signals in at least one signal represents the correspondence between signal groups of different signals, such as the correspondence between a downlink indication signal group and an excitation signal group, the correspondence between a downlink indication signal group and an uplink reflection signal group, the correspondence between a first downlink indication signal group and a second downlink indication signal group, and so on.

[0091] In some embodiments, the signal grouping information includes one or more of the number of signal groups, the identifier of the signal group, the index of the signal group, the signal type indication information, and the second correspondence information. The number of signal groups is used to indicate how many groups the signal is divided into. The identifier of the signal group or the index of the signal group is used to uniquely identify the corresponding signal group. The signal type indication information is used to indicate the type of signal, and the type of signal may include, for example, an A-IoT device-specific signal, an A-IoT device group-specific signal, a cell-specific signal, a query signal group-specific signal, and the like. The type of signal may also include, for example, which signal among the first signal and / or the second signal it is, such as: a first downlink indication signal, a second downlink indication signal, an excitation signal, an uplink reflected signal, an uplink transmission signal, and the like. The type of signal may also include, for example, which type of signal the signal belongs to, such as: a downlink signal or an uplink signal. The second correspondence information is used to indicate the correspondence between signal groups of different signals in at least one signal.

[0099] The association relationship between a device and a device group is used to indicate the group to which the device belongs. The first device determines the device group associated with the first device based on the association relationship between the device and the device group, which is the group of the first device.

[0100] 1.24. Equipment grouping criteria.

[0101] The device grouping criteria are used by the first device to determine the grouping of the first devices. The device grouping criteria may, for example, be grouping based on specific information, such as a device identifier, and performing a corresponding operation. The corresponding operation may include a modulo operation or other possible operation methods. For example, the first device may perform a modulo operation on the identifier of the first device based on the indication of the device grouping criteria, and determine the grouping of the first devices based on the calculation result.

[0102] 1.25. The first parameter is used to determine the device group.

[0103] The first parameter may include, for example, a parameter for generating signal grouping information. Device grouping may be determined based on the first parameter and device attribute parameters. The device attribute parameters may include, for example, a device index, a device identifier, and the like.

[0104] 1.26. The second parameter is used to identify a cell or a packet sequence.

[0105] A corresponding cell or group sequence may be determined based on the second parameter, and a signal grouping of the signal may be determined based on the corresponding cell or group sequence.

[0106] 1.27. Information related to the receiving and / or sending sequence of device groups.

[0107] The information related to the receiving and / or sending sequence of the device group is used to determine the receiving sequence and / or sending sequence of different device groups. The device group of the first device can be determined based on this information.

[0108] 1.28. Beam grouping information is used to indicate the device grouping information related to the beam.

[0109] For example, different device groups correspond to different beams, and airspace resources are divided by beams, and different device groups correspond to different airspace resources.

[0110] 1.29. Identification information, used to identify the uplink reflected signal and / or uplink transmitted signal of the received excitation signal in different beams.

[0111] The same excitation signal may transmit the same or different uplink reflected signals and / or uplink transmitted signals in different beams, which may be identified by identification information. The third device receives the uplink reflected signals and / or uplink transmitted signals sent by the first device in groups based on different beams.

[0112] 1.3. First correspondence information, used to indicate a correspondence between a signal group of at least one signal and a first device, or a correspondence between a signal group of at least one signal and a device group of the first device.

[0113] The first correspondence information includes one or more of the following items 1.31 to 1.34:

[0114] 1.31. A correspondence between a first device and a signal group of at least one signal in the first signal.

[0115] The correspondence between the first device and the signal group of at least one signal in the first signal may, for example, indicate at least one of the downlink indication signal group corresponding to the first device, the excitation signal group corresponding to the first device, and the carrier signal group corresponding to the first device.

[0121] The correspondence between the device group of the first device and the signal group of at least one signal in the second signal may, for example, indicate at least one of an uplink reflected signal group corresponding to the device group of the first device and an uplink transmitted signal group corresponding to the device group of the first device.

[0122] In the above embodiments, grouping information has been introduced. This grouping information can be used to determine the signal grouping of at least one signal, the device grouping of a first device, the correspondence between signal groups of different signals, the correspondence between the signal grouping of at least one signal and the first device, the correspondence between the signal grouping of at least one signal and the device grouping of the first device, and so on. Grouping resource information will now be introduced.

[0123] 2. Group resource information.

[0124] For the first device, the grouped resource information is used to indicate grouping information of resources for receiving the first signal and / or sending the second signal, and / or the association relationship between the resources for receiving the first signal and the resources for sending the second signal. For the second device or the third device, the grouped resource information is used to indicate grouping information of resources for sending the first signal and / or receiving the second signal, and / or the association relationship between the resources for sending the first signal and the resources for receiving the second signal.

[0125] First, grouping information of resources for receiving the first signal and / or sending the second signal is introduced.

In the embodiment of the present disclosure, the resources may include one or more of time domain resources, frequency domain resources, code domain resources, and spatial domain resources. Accordingly, by grouping the time domain resources, time domain resource grouping is obtained; by grouping the frequency domain resources, frequency domain resource grouping is obtained; by grouping the code domain resources, code domain resource grouping is obtained; and by grouping the spatial domain resources, spatial domain resource grouping is obtained.

[0127] In one implementation, the grouping resource information may include time domain resource grouping information, where the time domain resource grouping information is used to group time domain resources.

The time domain resource grouping may include a time domain resource grouping for receiving a first signal or a time domain resource grouping for transmitting a second signal. Time domain resources for multiple access transmission or multiple access reception may be determined based on the time domain resource grouping information.

[0129] By grouping time domain resources, different A-IoT devices can perform multiple-address transmission or multiple-address reception of the first signal and / or the second signal through a time division multiple access (TDMA) transmission mode.

[0130] In one implementation, the grouping resource information may include frequency domain resource grouping information, where the frequency domain resource grouping information is used to group frequency domain resources.

The frequency domain resource grouping may include a frequency domain resource grouping for receiving a first signal or a frequency domain resource grouping for transmitting a second signal. Frequency domain resources for multiple access reception or multiple access transmission may be determined based on the frequency domain resource grouping information.

[0132] By grouping frequency domain resources, different A-IoT devices can perform multiple access reception or multiple access transmission of the first signal and / or the second signal through a frequency division multiple access (FDMA) transmission mode.

[0133] In one implementation, the grouping resource information may include code domain resource grouping information, where the code domain resource grouping information is used to group code domain resources.

[0134] In some embodiments, the code domain resource grouping information includes: a sequence code corresponding to the code domain resource grouping. The code domain resources used for multiple access transmission can be determined based on the code domain resource grouping information.

[0135] By grouping code domain resources, different A-IoT devices can perform multiple-address reception or multiple-address transmission of the first signal and / or the second signal through a code division multiple access (CDMA) transmission mode.

[0136] In one implementation, the grouped resource information may include spatial resource grouping information, where the spatial resource grouping information is used to group spatial resources.

[0138] By grouping the airspace resources, different A-IoT devices can perform multiple-address reception or multiple-address transmission of the first signal and / or the second signal through a space division multiple access (SDMA) transmission mode.

[0139] The following describes an association relationship between a resource that receives a first signal and a resource that sends a second signal. The association relationship includes one or more of the following:

[0152] 2.4. Association between a resource location of a group in which a device group of the first device sends the second signal and the spatial domain information of the first signal.

[0178] For any signal among the first signal and the second signal, the multiple access transmission mode of the signal may include one or more of TDMA, FDMA, SDMA, and CDMA.

[0179] Different types of signals can use the same or different multiple access transmission modes. Specifically, one or more types of signals can use a multiple access transmission mode. The multiple access transmission mode of an uplink signal can be different from that of a downlink signal, such as the excitation signal and the uplink reflected signal, or the excitation signal and the uplink transmit signal. Different downlink signals can also use different multiple access transmission modes, such as the query signal carrying control information and the excitation signal.

[0180] The following describes specific implementations of different multiple access transmission modes with reference to the accompanying drawings.

[0181] The second device sends a first downlink indication signal (for example, a query signal) to the first device. The downlink indication signal carries downlink control information, that is, packet information.

[0182] First, the implementation process of the TDMA transmission method is introduced. In the following embodiment, the first device is an A-IoT device as an example.

[0183] Different signals of multiple devices (groups) can use the same multiple access transmission method or different multiple access transmission methods, wherein the signal includes a first signal and / or a second signal, the first signal includes one or more of a downlink indication signal, an excitation signal, and a carrier signal carrying downlink control information, and the second signal includes an uplink reflection signal and / or an uplink transmission signal.

[0184] The embodiments of the present disclosure are described using the TDMA transmission mode as an example, where different A-IoT devices (groups) transmit the first signal and / or the second signal at different time intervals. Specific implementations may include the following:

[0185] Implementation method 1: Different A-IoT devices (groups) receive downlink indication signals carrying downlink control information at different time periods.

[0186] Different A-IoT devices (groups) can determine the corresponding downlink indication signal receiving time point / receiving time period based on the first indication information, wherein the corresponding downlink indication signal receiving time point / receiving time period can be one or more of multiple sending locations within a specific time point or a specific time period.

[0187] FIG6 is a first schematic diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in FIG6 , an example is given of query signals being transmitted via a TDMA transmission mode, wherein the horizontal axis represents time and the vertical axis represents frequency.

[0188] As shown in Figure 6, the downlink indication signal is sent periodically or multiple times within a specific time period. Different periods of the downlink indication signal correspond to different A-IoT devices (groups), or different downlink indication signals correspond to different A-IoT devices (groups). The different periods of the downlink indication signal are exemplified by the first period and the second period in Figure 6, and different A-IoT devices (groups) are exemplified by device (group) 1 and device (group) 2 in Figure 6.

[0189] In the example of Figure 6, the first downlink indication signal can be sent by broadcast or by multicast. The first downlink indication signal includes grouping information. Based on the grouping information, each A-IoT device (group) can determine the time domain position for receiving its own second downlink indication signal.

[0190] For example, the device grouping of each A-IoT device (group) can be determined through the device grouping information, and the time domain resources for each A-IoT device (group) to receive the second downlink indication signal can be determined by combining the association between the device grouping of each A-IoT device (group) and the time domain resource grouping.

[0191] Taking the device grouping information including the device grouping identifier and the device grouping criterion as an example, where the device grouping criterion is to take the modulus of the device grouping identifier, each A-IoT device (group) performs a modulus value calculation based on its device grouping identifier ID to determine the corresponding device group, and combines the association between the device grouping of each A-IoT device (group) and the time domain resource grouping to determine the time domain resources for each A-IoT device (group) to receive the second downlink indication signal.

[0192] Taking the first correspondence information including the correspondence between the first device and the signal group of at least one signal in the first signal, or the correspondence between the device group of the first device and the signal group of at least one signal in the first signal as an example, each A-IoT device (group) can determine the signal group of the second downlink indication signal based on the first correspondence information, obtain the index of the signal group of the second downlink indication signal, and determine the time domain resources for each A-IoT device (group) to receive the second downlink indication signal in combination with the association between the group information and the group resource information.

[0193] The downlink indication signal corresponding to different A-IoT devices (groups) (such as the second downlink indication signal in Figure 6) carries the time-frequency resource information of one or more of the excitation signal and the uplink reflection signal / uplink transmission signal of the A-IoT device (group), wherein the second downlink indication signal can also indicate the time-frequency resource information of one or more of the excitation signal and the uplink reflection signal / uplink transmission signal of at least one A-IoT device in the A-IoT device (group). The time-frequency resource information of one or more of the excitation signal and the uplink reflection signal / uplink transmission signal of at least one A-IoT device in the A-IoT device (group) can have the same time interval as the second downlink indication signal.

[0194] As shown in Figure 6, under the instruction of the first downlink indication signal, the A-IoT device of device (group) 1 receives the second downlink indication signal at the corresponding time domain position within the first period, and sends an uplink reflection signal or an uplink transmission signal within the first period; the A-IoT device of device (group) 2 receives the second downlink indication signal at the corresponding time domain position within the second period, and sends an uplink reflection signal or an uplink transmission signal within the second period.

[0195] Implementation method 2: Different A-IoT devices (groups) receive excitation signals at different time periods.

[0196] Different A-IoT devices (groups) obtain time domain position-related information of the excitation signal received by the A-IoT device (group) based on the first indication information, wherein the method for obtaining the first indication information may include one or more of the protocol pre-configuration information, the downlink indication signal indication, and the device pre-stored information. The downlink indication signal indication method can be indicated by at least one of the first downlink indication signal carrying group information, the second downlink indication signal carrying group resource information, and the third downlink indication signal carrying the association relationship between the group information and the group resource information.

[0197] The first indication information is used to determine the time domain location related information of the A-IoT device (group) receiving the excitation signal, and may include, for example, one or more of the following:

[0198] The time interval between the A-IoT device (group) receiving the excitation signal and the start position of the downlink indication signal. The time interval corresponding to different A-IoT devices (groups) can be the same or different;

[0199] The time interval between the A-IoT device (group) receiving the excitation signal and the termination position of the downlink indication signal. The time interval corresponding to different A-IoT devices (groups) can be the same or different;

[0200] One or more of the start time, duration, and end time of receiving the excitation signal by the A-IoT device (group), for example, indicating that the excitation signal starts to be received at time point i;

[0201] A-IoT device identification;

[0202] A-IoT device group identifier;

[0203] The identifier of the downlink indication signal group;

[0204] The identifier or index of the stimulus signal;

[0205] Signal type indication information.

[0206] For the case where the first indication information carried by the downlink indication signal is used to indicate the excitation signals of different A-IoT devices (groups), there are many different implementation methods, which are introduced below in conjunction with Figures 7 and 8.

[0207] FIG7 is a second schematic diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in FIG7 , an example is given of an excitation signal being sent via a TDMA transmission mode, wherein the horizontal axis represents time and the vertical axis represents frequency.

[0208] In the example of FIG7 , the resource location of the excitation signal of one or more A-IoT devices (groups) may be indicated by information in the same downlink indication signal, that is, different A-IoT devices (groups) have independent information indication fields.

[0209] As shown in Figure 7, the downlink indication signal indicates that the time interval between the time domain start position of the excitation signal received by device (group) 1 and the time domain end position of the downlink indication signal is Gap1. Based on Gap1 and the time domain end position of the downlink indication signal of device (group) 1, the time domain start position of the excitation signal received by device (group) 1 can be determined. The downlink indication signal indicates that the time interval between the time domain start position of the excitation signal received by device (group) 2 and the time domain end position of the downlink indication signal is Gap2. Based on Gap2 and the time domain end position of the downlink indication signal of device (group) 2, the time domain start position of the excitation signal received by device (group) 2 can be determined.

[0210] FIG8 is a third schematic diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in FIG8 , an example is given of an excitation signal being sent via a TDMA transmission mode, wherein the horizontal axis represents time and the vertical axis represents frequency.

[0211] In the example of Figure 8, the resource location information of the excitation signals for different A-IoT devices (groups) is independently indicated by the information in the downlink indication signal. That is, the downlink indication signal carries the identifier of the A-IoT device (group) and the resource location information of the corresponding excitation signal. Only when the A-IoT device (group) receives the excitation signal corresponding to the corresponding device (group) identifier can it receive the excitation signal at the resource location of the corresponding excitation signal.

[0212] As shown in Figure 8, the downlink indication signal includes the identifier of device (group) 2 and the resource location information for device (group) 2 to receive the excitation signal. It indicates that the time interval between the time domain start position of device (group) 2 receiving the excitation signal and the time domain end position of the downlink indication signal is Gap2. Based on the indication of the downlink indication signal, device (group) 2 receives the corresponding excitation signal at the corresponding time domain position.

[0213] Furthermore, after receiving the excitation signal, at least one A-IoT device (group) transmits an uplink reflected signal or an uplink transmitted signal at a specific time or a specific time interval. The specific time interval includes the time interval between the time domain start position / time domain end position of the corresponding downlink indication signal, or the time domain start position / time domain end position of the corresponding excitation signal, etc. The specific time intervals corresponding to different A-IoT devices (groups) can be equal or different values.

[0214] Implementation method three: Different A-IoT devices (groups) send uplink reflected signals and / or uplink transmitted signals at different time periods.

[0215] Different A-IoT devices (groups) obtain information related to the time domain position of the uplink reflection signal and / or uplink transmission signal sent by the A-IoT device (group) based on the first indication information, wherein the method for obtaining the first indication information may include one or more of the protocol pre-configuration information, the downlink indication signal indication, and the device pre-stored information. The downlink indication signal indication method can be indicated by at least one of the first downlink indication signal carrying grouping information, the second downlink indication signal carrying grouping resource information, and the third downlink indication signal carrying the association relationship between the grouping information and the grouping resource information.

[0216] The first indication information is used to determine the time domain location-related information of the uplink reflected signal and / or uplink transmitted signal transmitted by the A-IoT device (group). For the case where the first indication information carried by the downlink indication signal is used to indicate the uplink reflected signal and / or uplink transmitted signal of different A-IoT devices (groups), there are multiple different implementation methods, which are described below in conjunction with Figures 9 and 10.

[0217] FIG9 is a fourth schematic diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in FIG9 , an example is given of an uplink reflected signal / uplink transmitted signal being transmitted via a TDMA transmission mode, wherein the horizontal axis represents time and the vertical axis represents frequency.

[0218] In the example of Figure 9, the downlink indication signal and the excitation signal are common signals for the cell or A-IoT device (group), that is, signals sent in a broadcast or multicast manner, and the first indication information carried by the downlink indication signal is used to indicate the time domain position of at least one A-IoT device (group) to send an uplink reflection signal or an uplink transmission signal. In the example of Figure 9, the time domain resource position of the uplink reflection signal / uplink transmission signal of one or more A-IoT devices (groups) can be indicated by the information in the same downlink indication signal, that is, different A-IoT devices (groups) have independent information indication domains. As shown in Figure 9, the downlink indication signal indicates that the time interval between the time domain termination position of the uplink reflection signal / uplink transmission signal sent by device (group) 1 and the downlink indication signal is Gap1, and also indicates that the time interval between the time domain termination position of the uplink reflection signal / uplink transmission signal sent by device (group) 2 and the downlink indication signal is Gap2.

[0219] FIG10 is a fifth schematic diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in FIG10 , an example is given of an uplink reflected signal / uplink transmitted signal being transmitted via a TDMA transmission mode, wherein the horizontal axis represents time and the vertical axis represents frequency.

[0220] The downlink indication signal is a signal common to a cell or A-IoT device (group), meaning it is sent in a broadcast format. The excitation signal is a signal common to the A-IoT device group, meaning it is multicast, with different excitation signals corresponding to different A-IoT device groups. The first indication information carried by the downlink indication signal indicates the time domain location at which at least one A-IoT device should transmit an uplink reflected signal / uplink transmitted signal within the time window of the corresponding excitation signal.

[0221] In the example of Figure 10, the time domain resource location of the uplink reflected signal / uplink transmitted signal of different A-IoT devices (groups) is independently indicated by the information in the downlink indication signal, that is, the downlink indication signal carries the identifier of the A-IoT device (group) and the time domain resource location information of the corresponding uplink reflected signal / uplink transmitted signal. Only when the A-IoT device (group) receives the identifier of the corresponding device (group) can it send the uplink reflected signal / uplink transmitted signal at the time domain resource location of the corresponding uplink reflected signal / uplink transmitted signal. As shown in Figure 10, the downlink indication signal includes the identifier of device (group) 2 and the time domain resource location information of the uplink reflected signal / uplink transmitted signal sent by device (group) 2, indicating that the time interval between the time domain starting position of the uplink reflected signal / uplink transmitted signal sent by device (group) 2 and the time domain ending position of the downlink indication signal is Gap2. Based on the indication of the downlink indication signal, device (group) 2 sends the corresponding uplink reflected signal / uplink transmitted signal at the corresponding time domain resource location.

[0222] The TDMA transmission mode is summarized and introduced below with reference to FIG11 and FIG12.

[0223] Figure 11 is a sixth schematic diagram of multiple access transmission provided in an embodiment of the present disclosure, and Figure 12 is a seventh schematic diagram of multiple access transmission provided in an embodiment of the present disclosure. As shown in Figures 11 and 12, an example is given of signals being sent via TDMA transmission, wherein the horizontal axis represents time and the vertical axis represents frequency.

[0224] In the example of Figure 11, the information carried in the first downlink indication signal indicates that device (group) 1 receives the excitation signal at a corresponding position in the time domain resource position within the first period, and sends an uplink reflected signal or an uplink transmitted signal within the first period; device (group) 2 receives the excitation signal at a corresponding position in the time domain resource position within the second period, and sends an uplink reflected signal or an uplink transmitted signal within the second period. The information carried in the second downlink indication signal further indicates the time domain resource position for sending the uplink reflected signal or the uplink transmitted signal. As shown in Figure 11, for example, it may include the time interval between the time when device (group) 1 sends the uplink reflected signal / uplink transmitted signal and the resource starting position of the second downlink indication signal, the time interval between the time when device (group) 1 sends the uplink reflected signal / uplink transmitted signal and the resource ending position of the second downlink indication signal, and so on.

[0225] In the example of Figure 12, the information carried in the first downlink indication signal indicates that device (group) 1 receives the excitation signal at the corresponding position in the time domain resource position within the first period, and sends an uplink reflection signal or an uplink transmission signal within the first period; device (group) 2 receives the excitation signal at the corresponding position in the time domain resource position within the second period, and sends an uplink reflection signal or an uplink transmission signal within the second period. Among them, the time domain resource position for sending the uplink reflection signal or the uplink transmission signal is further indicated by the information carried in the second downlink indication signal. As shown in Figure 12, the resource location information of the excitation signal, uplink reflection signal, and uplink transmission signal of different A-IoT devices (groups) is independently indicated by the information in the second downlink indication signal, that is, the second downlink indication signal carries the identifier of the A-IoT device (group) and the resource location information of the corresponding excitation signal, uplink reflection signal, and uplink transmission signal. As shown in FIG12 , two different second downlink indication signals are used to respectively indicate the resource location information of the excitation signal, uplink reflected signal, and uplink transmitted signal of device (group) 1 and device (group) 2. The resource location information may include, for example, the time interval between the device (group) sending the uplink reflected signal / uplink transmitted signal and the resource starting position of the second downlink indication signal, the time interval between the device (group) sending the uplink reflected signal / uplink transmitted signal and the resource ending position of the second downlink indication signal, and so on.

[0226] The implementation process of the FDMA transmission method is introduced below.

[0227] Different signals of multiple devices (groups) can use the same multiple access transmission method or different multiple access transmission methods, wherein the signal includes a first signal and / or a second signal, the first signal includes one or more of a downlink indication signal, an excitation signal, and a carrier signal carrying downlink control information, and the second signal includes an uplink reflection signal and / or an uplink transmission signal.

[0228] The embodiments of the present disclosure use FDMA transmission as an example to illustrate that different A-IoT devices (groups) receive the first signal and / or send the second signal at different time intervals. Specific implementations may include the following: Implementations 4 to 5.

[0229] Implementation method 4: Each A-IoT device (group) uses FDMA transmission to send uplink reflection signals / uplink transmission signals.

[0230] The downlink indication signal is sent at full bandwidth to indicate information related to the receiving resources of the excitation signal and / or information related to the sub-band where the A-IoT device (group) sends the uplink reflected signal / uplink transmitted signal.

[0231] Implementation mode 4 is described below in conjunction with Figure 13. Figure 13 is a schematic diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in Figure 13, an example is that a signal is sent via FDMA transmission, where the horizontal axis represents time and the vertical axis represents frequency.

[0232] As shown in Figure 13, the downlink indication signal indicates the offset between the frequency domain resource position of the excitation signal and the frequency domain resource position of the uplink reflection signal / uplink transmission signal sent by the A-IoT device (group). Based on the offset and the frequency domain resource position of the excitation signal, the frequency domain resource position of the uplink reflection signal / uplink transmission signal sent by the A-IoT device (group) can be obtained.

[0233] Implementation method five: The excitation signal is received using FDMA, and the downlink indication signal is sent at the full bandwidth. The second device can perform frequency division multiplexing (FDM) on at least one excitation signal through the downlink indication signal, that is, the excitation signals are sent separately on different sub-bandwidths, corresponding to different A-IoT devices (groups).

[0234] Implementation mode 5 is described below in conjunction with Figure 14. Figure 14 is a ninth diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in Figure 14, an example is given of signals being transmitted using an FDMA transmission mode, where the horizontal axis represents time and the vertical axis represents frequency.

[0235] As shown in Figure 14, the downlink indication signal indicates the offset between the frequency domain resource position of the excitation signal and the frequency domain resource position of the uplink reflection signal / uplink transmission signal sent by the A-IoT device (group). Based on the offset and the frequency domain resource position of the excitation signal, the frequency domain resource position of the uplink reflection signal / uplink transmission signal sent by the A-IoT device (group) can be obtained.

[0236] When an A-IoT device can receive signals in a sub-bandwidth, it can perform filtering. The A-IoT device (or group) transmits an uplink reflected signal / uplink transmitted signal based on the grouping information of the downlink indication signal and information related to the excitation signal. The frequency domain resource location where the A-IoT device (or group) transmits the uplink reflected signal / uplink transmitted signal is offset from the frequency domain resource location of the corresponding excitation signal.

[0237] The following describes the implementation process of the CDMA transmission method. In the following embodiments, the first device is an A-IoT device as an example.

[0238] Different signals of multiple devices (groups) can use the same multiple access transmission method or different multiple access transmission methods, wherein the signal includes a first signal and / or a second signal, the first signal includes one or more of a downlink indication signal, an excitation signal, and a carrier signal carrying downlink control information, and the second signal includes an uplink reflection signal and / or an uplink transmission signal.

[0239] The embodiments of the present disclosure are described using a CDMA transmission method as an example, where different A-IoT devices (groups) transmit the first signal and / or the second signal at different time intervals. Specifically, the following implementation methods 6 to 7 may be included.

[0240] Implementation method six: The downlink indication signal uses CDMA to group A-IoT devices (groups).

[0241] For example, the first downlink indication signal sends a first parameter to the A-IoT device. The first parameter is a parameter used to generate grouping information and is used to determine device grouping. The first parameter can be used to determine one or more of the following: the signal grouping of the second downlink indication signal, the signal grouping of the excitation signal, the signal grouping of the uplink reflected signal, and the signal grouping of the uplink transmitted signal.

[0242] After receiving the parameters for generating grouping information, the A-IoT device performs specific operations (such as modulus calculation) based on its own attribute parameters (such as device identification) to obtain the device grouping information of the A-IoT device. The relevant parameters or parameter sets for determining the grouping include at least the number of groups.

[0243] For example, the second downlink indication signals sent by different network devices or relay devices use a CDMA transmission method. The network device or relay device can send a second parameter to the A-IoT device via the first downlink indication signal. The second parameter is a relevant parameter used to identify the current cell or the corresponding packet sequence. When the A-IoT device receives multiple second downlink indication signals, the A-IoT device group determines the second downlink indication signal corresponding to the corresponding group based on the relevant parameter used to identify the current cell or the corresponding packet sequence.

[0244] Implementation method seven: The downlink indication signal uses CDMA to group A-IoT devices (groups).

[0245] The downlink indication signal sends information related to the reception and / or transmission sequence of the device group to the A-IoT device. For example, it may include information related to the codeword used to distinguish it from other devices. This information can be used by the A-IoT device to generate a sequence for identifying itself. This sequence can be mutually orthogonal to other devices that simultaneously transmit uplink reflected signals / uplink transmitted signals. For example, the sequence may include an M sequence, a Gold sequence, a ZC sequence, etc. The relevant information carried by the uplink reflected signal / uplink transmitted signal sent by the A-IoT device may include, for example, the initial value, cyclic shift, or root sequence of the corresponding sequence.

[0246] The following describes the implementation process of the SDMA transmission method. In the following embodiment, the first device is an A-IoT device as an example.

[0247] Different signals of multiple devices (groups) can use the same multiple access transmission method or different multiple access transmission methods, wherein the signal includes a first signal and / or a second signal, the first signal includes one or more of a downlink indication signal, an excitation signal, and a carrier signal carrying downlink control information, and the second signal includes an uplink reflection signal and / or an uplink transmission signal.

[0248] The embodiment of the present disclosure is illustrated by taking the SDMA transmission mode of the signal as an example, and different A-IoT devices (groups) receive the first signal and / or send the second signal at different time intervals.

[0249] Implementation method eight: The downlink indication signal is sent using different beams. The downlink indication signal carries beam grouping information, as well as the excitation signal and the resource location information of the uplink reflection signal / uplink transmission signal sent by the A-IoT device (group). The beam grouping information is used to indicate the device grouping information related to the beam. Different device groups use different beams for signal multiple access reception or multiple access transmission.

[0250] Implementation method nine: The downlink indication signal carries identification information for identifying the uplink reflected signal and / or uplink transmitted signal of the received excitation signal under different beams. The excitation signal received by the A-IoT device (group) is sent under different beams, and the uplink reflected signal / uplink transmitted signal is sent based on the excitation signal under the current beam. The third device groups and receives the uplink reflected signal / uplink transmitted signal sent by the A-IoT device (group) based on different beams.

[0251] Figure 15 is a schematic diagram of multiple access transmission provided by an embodiment of the present disclosure. As shown in Figure 15, an example is given of a signal being transmitted through an SDMA transmission method. In the example of Figure 15, three beams are included, namely beam 1, beam 2, and beam 3, and different beams represent different airspace resources. In the example of Figure 15, three different A-IoT devices (groups) are included, namely device (group) 1, device (group) 2, and device (group) 3. Among them, device (group) 1 and the third device perform multiple access transmission of signals through beam 1; device (group) 2 and the third device perform multiple access transmission of signals through beam 2; device (group) 3 and the third device perform multiple access transmission of signals through beam 3.

[0252] In summary, the solution disclosed in the present invention realizes multiple access transmission of the signal of the first device based on the first indication information, including different multiple access transmission modes such as TDMA, FDMA, CDMA, SDMA, etc., reducing the interference caused by simultaneous access collisions of multiple devices, thereby improving the network capacity for the device.
