[0097] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0098] 1. AIoT device types:

[0099] In the AIoT research, ambient IoT devices are characterized based on their energy storage capacity and their ability to generate radio frequency signals for transmission. The A-IoT device has one of the following energy storage capabilities:

[0100] Storage capacity 1: No ability to store energy;

[0101] Storage capacity 2: Energy can be stored up to E1 or E2 joules, where it is possible for E1 = E2;

[0102] Storage capacity3: Energy can be stored up to E2 joules.

[0103] Depending on these storage capacities, the following set of ambient IoT devices is considered:

[0104] Device A: No energy storage, no independent signal generation or amplification, i.e. backscatter transmission;

[0105] Device B: has energy storage but no independent signal generation, i.e. backscatter transmission. Utilization of stored energy may include amplification of the reflected signal.

[0106] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0107] Devices with different energy storage capacities also affect their transmission quality. Generally, devices with higher energy storage also have higher receive sensitivity or higher transmit power, which means that the reliability of the receive or transmit link can be better guaranteed.

[0108] 2. AIoT business types.

[0109] The main data or business types of AIoT include:

[0110] DO:Device-originated;

[0111] DT: Device-terminated.

[0112] DO traffic includes DO autonomous (DO-A) and DO device-terminated triggered (DO-DTT).

[0113] DO-A refers to autonomous data transmission initiated by AIoT devices. For example, these devices can connect to a large number of various sensors that collect and, when necessary, proactively report information about the environment, devices, and organisms.

[0114] DO-DTT refers to data transmission initiated by an AIoT device, triggered by a reader or writer (e.g., a network-side device). For example, asset identification, status reporting, and tracking are all DL-triggered reports, where the reader collects data from the tag by triggering an inventory process. Because the data is generated or initiated by the IoT device, this service should be considered a DO service initiated by the tag, triggered by a reader-side control command.

[0115] 3. Topology

[0116] Topology 1: Network-side devices and ambient IoT devices, as shown in Figure 2.

[0117] Topology 2: Network-side devices, intermediate nodes, and ambient IoT devices, as shown in Figure 3.

[0118] 4. Sending and receiving flow chart.

[0119] In inventory mode, the reader sends a query command (Query), and the tag responds (Reply), generating a 16-bit random number for the reader. The reader then sends this sequence to the tag via an acknowledgment (ACK) command, and the tag sends the relevant data to the reader.

[0120] Specifically, the process of querying and accessing a single tag is shown in Figure 4.

[0121] 5. Commonly used control commands in Radio Frequency Identification (RFID) are shown in Figure 5.

[0122] The operation commands for the reader are shown in the following table:

[0123] It should be noted that in this application, uplink or downlink are all from the perspective of the device itself:

[0124] For example, the network-side device acts as a reader and the command is sent in the FDD DL spectrum;

[0125] For example, the terminal acts as a reader and the command is sent in the FDD UL spectrum.

[0126] For example, the DL command is from the Tag's perspective. Regardless of whether the reader is a terminal or a network-side device, the Tag's receiving direction is DL and the sending direction is UL.

[0127] The transmission processing method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0128] 6 , an embodiment of the present application provides a transmission processing method. As shown in FIG6 , the transmission processing method includes:

[0129] Step 601: The first device determines a downlink receiving resource for a first signal according to first information;

[0130] Step 602: The first device receives the first signal in the downlink receiving resource;

[0131] The first information includes at least one of the following:

[0132] first indication information, where the first indication information is used to indicate whether to switch at least one of a frequency domain receiving position and a target resource position, where the target resource position is an absolute resource position or a relative resource position offset;

[0133] The frequency domain position of a continuous wave (CW);

[0134] Parameters associated with the first signal;

[0135] The device type of the sending device of the first signal.

[0136] In an embodiment of the present application, determining the downlink reception resource of the first signal may be connected to or replaced with determining the downlink reception position of the first signal, wherein the downlink reception resource may be an FDD DL spectrum (i.e., an FDD DL frequency domain resource) or an FDD UL spectrum (i.e., an FDD UL frequency domain resource).

[0137] Optionally, switching the frequency domain receiving position may include any one of the following: switching the receiving frequency band (switching between FDD DL spectrum and FDD UL spectrum), and switching different frequency domain positions in the same spectrum.

[0138] Optionally, the first information may be agreed upon by a protocol, indicated by a network device, or obtained by the first device through detection. For example, the network device may indicate the first indication information, parameters associated with the first signal, and the type of the device sending the first signal. The protocol may agree upon the parameters associated with the first signal; the first device may obtain the frequency domain position of the continuous wave by detecting the continuous wave.

[0139] Optionally, the device type of the transmitting device may include a terminal and a network-side device. If the transmitting device is a network-side device, the downlink receiving resource may be an FDD DL spectrum, i.e., the first device can receive commands sent by the network-side device on the FDD DL spectrum. If the transmitting device is a terminal, the downlink receiving resource may be an FDD UL spectrum, i.e., the first device can receive commands sent by the network-side device on the FDD UL spectrum.

[0140] It should be noted that, in the embodiment of the present application, the above-mentioned first device can be understood as an AloT device that supports two readers.

[0141] In an embodiment of the present application, a first device determines a downlink receiving resource for a first signal based on first information; the first device receives the first signal at the downlink receiving resource; wherein the first information includes at least one of the following: first indication information, the first indication information being used to indicate whether to switch at least one of a frequency domain receiving position and a target resource position, the target resource position being an absolute resource position or a relative resource position offset; a frequency domain position of a continuous wave; associated parameters of the first signal; and a device type of a transmitting device of the first signal. Thus, in an embodiment of the present application, the definition of the first information that can be used to determine the downlink receiving resource for the first signal is clarified, thereby enabling an AloT device that supports two readers to determine the downlink receiving resource based on the first information and implement the transmission of commands for the FDD UL spectrum and the FDD DL spectrum.

[0142] Optionally, in some embodiments, when the first information includes the first indication information, and the first indication information is a switching frequency domain receiving position, the downlink receiving resource satisfies at least one of the following:

[0143] In a case where the first device receives the first indication information in a frequency division duplex downlink FDD DL frequency domain resource, the downlink receiving resource is a frequency division duplex uplink FDD UL frequency domain resource;

[0144] In a case where the first device receives the first indication information in an FDD UL resource, the downlink reception resource is an FDD DL frequency domain resource.

[0145] In an embodiment of the present application, when the current reader is a network side device, the network side device can send a first indication information in the FDD DL frequency domain resource, the first device can receive the first indication information in the FDD DL frequency domain resource, and determine the downlink receiving resource based on the first indication information. For example, if the first indication information indicates switching the receiving frequency band, it can be determined that the downlink receiving resource is an FDD UL frequency domain resource, and the first device receives the terminal's command in the FDD UL frequency domain resource after switching; if the first indication information indicates a different frequency domain position in the same spectrum, it can be determined that the downlink receiving resource is an FDD DL frequency domain resource, that is, the receiving resource or receiving position is re-determined in the FDD DL frequency domain resource, and the first device continues to receive the command of the network side device in the FDD DL frequency domain resource after switching.

[0146] When the current reader is a terminal, the terminal can send a first indication information in the FDD UL frequency domain resource, the first device can receive the first indication information in the FDD UL frequency domain resource, and determine the downlink receiving resource based on the first indication information. For example, if the first indication information indicates switching the receiving frequency band, it can be determined that the downlink receiving resource is an FDD DL frequency domain resource, and the first device receives the command of the network side device in the FDD DL frequency domain resource after the switch; if the first indication information indicates a different frequency domain position in the same spectrum, it can be determined that the downlink receiving resource is an FDD UL frequency domain resource, that is, the receiving resource or receiving position is re-determined in the FDD UL frequency domain resource, and the first device continues to receive the terminal's command in the FDD UL frequency domain resource after the switch.

[0147] Optionally, in some embodiments, the absolute resource location is used to indicate that the first device receives the first signal in FDD UL or FDD DL;

[0148] Alternatively, the relative resource location offset is an offset from a resource location where the first device currently receives a signal.

[0149] For example, if the first device is currently in the FDD DL frequency domain, the first device is adjusted to the FDD UL frequency domain to receive the first signal by offsetting 5 MHz. It should be understood that the above offset can be an upward offset or a downward offset, that is, the DL frequency domain position is equal to the UL frequency domain position ± 5 MHz.

[0150] Optionally, in some embodiments, the relative resource location offset is an absolute value (such as 1 MHz) or a relative value of the associated backscatter link frequency BLF (such as 3 times BLF, or BLF+5 MHz).

[0151] It should be noted that switching the frequency domain receiving position based on the relative resource position may also include any of the following: switching the receiving frequency band (switching between FDD DL spectrum and FDD UL spectrum), and switching between different frequency domain positions in the same spectrum.

[0152] Optionally, in some embodiments, when the first information includes the frequency domain position of the continuous wave, the first device determining the downlink reception resource of the first signal according to the first information includes:

[0153] The first device determines, according to the first information and a target mapping relationship, a downlink reception resource of the first signal, where the target mapping relationship is used to identify a frequency domain position of continuous carriers and a frequency domain position of the first signal;

[0154] The target mapping relationship includes any of the following:

[0155] First mapping relationship: uplink consecutive carriers are associated with UL frequency domain positions of the first signal, and downlink consecutive carriers are associated with DL frequency domain positions of the first signal;

[0156] Second mapping relationship: uplink consecutive carriers are associated with the DL frequency domain position of the first signal, and downlink consecutive carriers are associated with the UL frequency domain position of the first signal.

[0157] Optionally, in some embodiments, the downlink receiving resource satisfies at least one of the following: when the first device detects a CW at an uplink frequency domain position through blind detection, the downlink receiving resource is an FDD UL frequency domain resource; when the first device detects a CW at a downlink frequency domain position through blind detection, the downlink receiving resource is an FDD DL frequency domain resource;

[0158] Alternatively, the downlink receiving resource satisfies at least one of the following: when the first device detects CW in the uplink frequency domain position through blind detection, the downlink receiving resource is an FDD DL frequency domain resource; when the first device detects CW in the downlink frequency domain position through blind detection, the downlink receiving resource is an FDD UL frequency domain resource.

[0159] In an embodiment of the present application, the first device can obtain the frequency domain position of the CW through blind detection, thereby determining the frequency domain position of the first signal. For example, when the first device detects the CW at the uplink frequency domain position through blind detection, it can be determined that the frequency domain position of the CW is the uplink frequency domain position, so that the downlink receiving resource can be determined as the FDD UL frequency domain resource based on the first mapping relationship, and the first device can receive the first signal in the FDD UL frequency domain resource; or the downlink receiving resource can be determined as the FDD DL frequency domain resource based on the second implicit relationship, and the first device can receive the first signal in the FDD DL frequency domain resource.

[0160] For another example, when the first device detects CW in the downlink frequency domain position through blind detection, it can be determined that the frequency domain position of the CW is the downlink frequency domain position, so that the uplink receiving resource can be determined as the FDD DL frequency domain resource based on the first mapping relationship, and the first device can receive the first signal in the FDD DL frequency domain resource; or based on the second mapping relationship, it can be determined that the uplink receiving resource is the FDD UL frequency domain resource, and the first device can receive the first signal in the FDD UL frequency domain resource.

[0161] It should be noted that the target mapping relationship can be predefined, network-indicated, or agreed upon by a protocol, wherein predefined can be understood as pre-specified by the device manufacturer. The network indication can include but is not limited to a network-side device indication or a terminal indication.

[0162] Optionally, in some embodiments, the associated parameters of the first signal include at least one of the following: bandwidth, BLF, division ratio, tag-to-interrogator calibration symbol (TRcal), reader-to-tag calibration symbol (RTcal), modulation mode, preamble, frame synchronization, signal type and encoding mode.

[0163] Optionally, the above-mentioned downlink receiving resources can be determined based on the bandwidth of the first signal. For example, the bandwidth of the first signal is in the MHz level, and the first device receives the first signal in the FDD DL frequency domain resources; the bandwidth of the first signal is in the KHz level, and the first device receives the first signal in the FDD UL frequency domain resources, and vice versa.

[0164] Optionally, the downlink reception resources may be determined based on BLF. For example, when BLF=40 KHz, the first device receives the first signal in FDD DL frequency domain resources. When BLF=960 KHz, the first device receives the first signal in FDD UL frequency domain resources.

[0165] Optionally, the downlink receiving resources may be determined based on a divide ratio (DR), such as DR=64 / 3, the first device receives the first signal in FDD DL frequency domain resources, DR=8, the first device receives the first signal in FDD UL frequency domain resources, and vice versa.

[0166] Optionally, the downlink receiving resource may be determined based on TRcal or RTcal, where TRcal=0length+1length, that is, RTcal is the length of symbol 0 plus the length of symbol 1, and 1.1*RTcal≤TRcal≤3*RTcal.

[0167] For example, when TRcal is a first value, the first device receives the first signal in the FDD DL frequency domain resources, and when TRcal is a second value, the first device receives the first signal in the FDD UL frequency domain resources, or vice versa.

[0168] Optionally, the downlink receiving resources may be determined based on a modulation method, such as double sideband Amplitude Shift Keying (DSB-ASK), single sideband amplitude-shift keying (SSB-ASK) or Phase Reverse Amplitude Shift Keying (PR-ASK), for example, in DSB-ASK modulation, the first device receives the first signal in the FDD DL frequency domain, and in SSB-ASK, the first device receives the first signal in the FDD UL frequency domain.

[0169] Optionally, the downlink receiving resources may be based on a preamble or frame-sync. For example, the signal structure starts with a preamble, and the first device receives the first signal in the FDD DL frequency domain. It starts with a frame-sync, and the first device receives the first signal in the FDD UL frequency domain.

[0170] Optionally, the downlink receiving resources may be determined based on a signal type. For example, for an inventory type signal, the first device receives the first signal in an FDD DL frequency domain; for a selection type signal, the first device receives the first signal in an FDD UL frequency domain.

[0171] Optionally, the downlink receiving resources can be determined based on a coding method. For example, the reader to tag adopts pulse interval encoding (PIE) coding. Considering the assumption that there will be other coding methods in the future, it can be determined by the coding method, such as PIE coding. The first device receives the first signal in the FDD DL frequency domain. For other coding methods, the first device receives the first signal in the FDD UL frequency domain.

[0172] Optionally, in some embodiments, when the first information includes a device type of a sending device of the first signal, the downlink receiving resource satisfies at least one of the following:

[0173] In a case where the device type of the sending device of the first signal is a terminal, the downlink receiving resource is a frequency division duplex uplink FDD UL frequency domain resource;

[0174] In a case where the device type of the sending device of the first signal is a network-side device, the downlink receiving resource is an FDD DL frequency domain resource.

[0175] In the embodiment of the present application, whether to switch the receiving frequency band can be determined by indicating the device type.

[0176] Optionally, in some embodiments, the method further comprises:

[0177] The first device receives a second signal from a second device, where the second signal is used to determine the first information.

[0178] In the embodiment of the present application, the above-mentioned second device can be understood as a device that currently serves as a reader of the first device. For example, if the current reader is a terminal, the second device can be a terminal; if the current reader is a network side device, the second device can be a network side device.

[0179] It should be noted that, in the embodiment of the present application, the second device may actively send the second signal to the first device, or the third device may trigger the second device to send the second signal to the first device.

[0180] For example, when the first device is currently in the FDD DL frequency domain receiving position, the network side device can actively send the second signal, or the terminal sends second information (such as a request message) to the network side device to request the network side device to send the second signal.

[0181] For another example, when the first device is currently in the FDD UL frequency domain receiving position, the terminal may actively send the second signal, or the network side device may send second information (such as an indication message) to the terminal to instruct the terminal to send the second signal.

[0182] Optionally, in some embodiments, the method further comprises:

[0183] The first device sends feedback information to the second device or the third device, where the feedback information is used to indicate confirmation of switching. The third device is a device that communicates with the first device after switching the frequency domain receiving position.

[0184] In an embodiment of the present application, the device before switching and the device after switching can be the same device or different devices. For example, if the receiving frequency band is switched, the device before switching and the device after switching are different devices; if only different frequency domain positions in the same spectrum are switched, the device before switching and the device after switching are the same device.

[0185] Optionally, in some embodiments, the first information includes at least one of a downlink control command and downlink data.

[0186] Specifically, such as selection, inventory, access (such as read, write, lock and other commands), paging, scheduling, random access response, and contention resolution information.

[0187] It should be noted that, with respect to the structure of the receiver, the structure of the receiver of the first device may include any of the following:

[0188] a first filter, wherein a receiving bandwidth of the first filter covers a frequency division duplex downlink FDD DL spectrum and a frequency division duplex uplink FDD UL spectrum;

[0189] The second filter and the third filter, the receiving bandwidth of the second filter covers the FDD DL spectrum, and the receiving bandwidth of the third filter covers the FDD UL spectrum.

[0190] In the embodiment of the present application, coverage of the FDD DL spectrum and the FDD UL spectrum can be achieved through one filter, so that the FDD DL signal and the FDD UL signal can be directly received without obtaining the above-mentioned first information, thereby simplifying the operation difficulty.

[0191] The second filter and the third filter can also be used to respectively realize reception of different spectrums, that is, the filter can be switched or not based on the downlink reception resource of the first signal determined by the first information. In this way, the hardware cost of the filter can be reduced.

[0192] In order to better understand the present application, some examples are provided below for illustration.

[0193] Example 1: As shown in FIG7 , a tag has a filter.

[0194] In one embodiment, the tag filter ranges from f1 to f2, representing a wideband filter. A DL command is transmitted at frequency f3, and a UL command is transmitted at frequency f4. The frequency domain locations of f3 and f4 lie between f1 and f2, meaning the tag filter can include both the DL command spectrum and the UL command spectrum. The tag does not switch the reception location of the first signal.

[0195] In another embodiment, after CW activates the AIoT device, the AIoT device detects the command in the frequency domain range of f1 to f2, where f2≤f≤[(f2-f1) / 2-F_GB] is FDD uplink; [(f2-f1) / 2+F_GB]≤f≤f1 is FDD downlink, where F_GB is the protection interval between the traditional FDD uplink and downlink spectrum. When the AIoT device detects command#1 when f2≤f≤[(f2-f1) / 2-F_GB] or [(f2-f1) / 2+F_GB]≤f≤f1, and this command#1 causes the AIoT to start a new round of inventory, the frequency domain range of all commands from the reader during this round of inventory is consistent with the frequency domain range of the detected command#1; or command#1 can indicate the frequency domain range of subsequent commands from the reader during this round of inventory, and the frequency domain range of subsequent commands can be different from the frequency domain range of command#1, such as completely non-overlapping or partially overlapping, or the frequency domain range of subsequent command#(n+1) is indicated by the previous command#n. Through this method, the AIoT device (tag) can narrow the frequency domain range of the command, which is beneficial for baseband optimization.

[0196] Example 2: As shown in FIG8 , there are two filters for the tag.

[0197] In one embodiment, the tag has filters of different frequency bands, where filter 1 is used to receive FDD DL commands and filter 2 is used to receive UL commands. The tag needs to switch between filters according to whether the current command comes from the UE or the base station.

[0198] One way to directly determine whether the tag is switched is through direct indication. The tag first receives the first indication information and determines the reception spectrum of the command according to the first indication information.

[0199] One approach is for the tag to continuously receive CWs when not communicating with the reader to conserve energy. When the CW's frequency domain position maps to the frequency domain positions of the DL command and the UL command, the tag blindly detects the CW's frequency domain position to determine the command's frequency domain position. The simplest mapping is to associate a DL CW with a DL command, a UL CW with a UL command, or vice versa.

[0200] One way is to use the frequency domain offset to determine the frequency domain position of the command. The tag uses the current filter position as the reference and determines the command position by offsetting it by 5MHz.

[0201] One embodiment is to determine the frequency domain position of the command through the mapping relationship between signal parameters and signals. Taking signal bandwidth as an example, the DL command signal bandwidth from the base station is in the MHz level, and the UL command signal bandwidth from the UE is in the KHz level. The tag can determine whether to switch to filter 1 or filter 2 based on the current signal bandwidth.

[0202] One way is to determine it through blind detection, that is, after CW activates the AIoT device, the AIoT device selects (predefined) or is determined by the protocol to first try to receive the reader's downlink transmission, such as preamble, command, in the frequency domain range covered by Filter 1 or filter 2. If a valid transmission from the reader is detected, the AIoT device determines the frequency domain range for receiving the command; if no valid transmission from the reader is received within the first time after CW activation, the AIoT device switches to filter 2 or filter 1 to detect valid transmission from the reader.

[0203] Optionally, the above-mentioned first time can be determined by protocol agreement, network side device configuration or based on a timer. For example, in some embodiments, after CW activates the AIoT device, the timer is started. During the operation of the timer, a Filter detects the downlink transmission from the reader. If no valid transmission from the reader is received during the operation of the timer, it switches to another Filter to detect the downlink transmission from the reader.

[0204] Example 3: Feedback confirmation information, including two situations:

[0205] 1. Confirm pre-switching feedback, that is, the tag receives the switching instruction and sends an ACK to the reader before executing the switching instruction, including any of the following:

[0206] a) The handover command is sent by the base station or the UE requests the base station to send it, requiring switching from the FDD DL spectrum to the FDD UL spectrum. After receiving the handover command, the tag feeds back an ACK to the base station;

[0207] b) The switching command is sent by the UE or instructed by the network side device to be sent by the UE. It is necessary to switch from the FDD UL spectrum to the FDD DL spectrum. After receiving the switching command, the tag feeds back an ACK to the UE.

[0208] 2. Feedback confirmation information after switching, that is, the tag sends an ACK to the reader after executing the switching instruction, which includes any of the following:

[0209] a) After the tag switches from the current FDD DL spectrum to the FDD UL spectrum, an ACK is fed back to the UE;

[0210] b) After the Tag switches from the current FDD UL spectrum to the FDD DL spectrum, it feeds back an ACK to the base station.

[0211] The feedback time required for the above feedback can be predefined, specified by the protocol, instructed by the network-side device, and determined based on the device type. For example, passive devices have a longer feedback time, while active devices have a shorter feedback time; devices that can only communicate with backscatter have a longer feedback time, while devices that can autonomously generate UL signals have a shorter feedback time.
