[0087] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0088] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 , wherein the network device includes at least one of the following: an access network device and a core network device.

[0089] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0090] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0091] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0092] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0093] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0094] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0095] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0096] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0097] In some embodiments, when a network device communicates with a terminal, the terminal can function as an Ambient IoT device, and the network device can function as a reader. In some scenarios, the terminal can also function as a tag to communicate with the network device. Ambient IoT, referred to as A-IoT, lacks RF transmission capabilities and requires backscattering to transmit data, such as sensor data from the A-IoT device.

[0098] In some embodiments, the network device can perform an inventory of the terminals. Before performing the inventory service, the network device can first perform a selection operation, such as selecting one or more terminals in a terminal group (such as terminals in a cell of the network device) through a select command, and then for the selected terminals, the encryption and authentication type of the terminals can be queried through a challenge command.

[0099] In some embodiments, a network device can perform an inventory of terminals. The inventory service begins when the network device sends a query command to the terminal and ends when the network device sends a query command again, or sends a selection command or a challenge command to the terminal. For example, the network device can send a first query command to multiple terminals to start a first round of inventory service. When a second query command is sent to the terminal, the first round of inventory service ends and a second round of inventory service begins.

[0100] In some embodiments, the terminal may repeatedly send the first query command (QueryRep) during the first round of inventory counting. In this case, the first round of inventory counting does not end.

[0101] For example, after receiving a query command, the terminal can enter the arbitrate state, which can be considered a holding state. The query command carries an indicator value, such as a Q value. Based on the Q value, the terminal can determine a counter value and decrement the counter value by 1 each time it receives a QueryRep. When the counter value reaches 0, the terminal transitions to the reply state and sends a sequence, such as a 16-bit random number sequence (RN16), to the network device via backscatter.

[0102] After receiving the RN16 sequence sent by the terminal, the network device may send a first acknowledgment (ACK#1) to the terminal if it allows access. Upon receiving the first acknowledgment, the terminal may determine that access is successful. Otherwise, if the terminal receives an invalid acknowledgment, or an acknowledgment with an erroneous RN16, or if the first acknowledgment is not received within a certain period of time (e.g., T2, which may be specified by the protocol or indicated by the network), access is determined to have failed, and the terminal returns to the adjudication state.

[0103] In some embodiments, the terminal can determine the access timing based on QueryRep, such as the time interval between two adjacent QueryReps, which can be used for the terminal to access the network device, such as sending the above-mentioned RN16 sequence to the network device. For example, the access process can be implemented based on random access.

[0104] In some embodiments, after determining that the access is successful, the terminal may send the perception information acquired by the terminal, the device identification (Device ID) of the terminal, etc. to the network device.

[0105] It should be noted that the count values ​​generated by different terminals based on the Q value can be different. This results in the network device determining whether some terminals generate smaller count values ​​and complete access relatively early, while others generate larger count values ​​and complete access relatively late. This means that while some terminals have completed access, others are still performing inventory checks.

[0106] In some embodiments, after the network device determines that the terminal has successfully accessed, it may perform a communication service other than the inventory service with the terminal, such as a first communication service.

[0107] However, there are still some technical issues that need to be resolved when performing the first communication service. For example, as mentioned above, although the terminal can send its device identifier to the network device, in some cases, the terminal's device identifier is transparently transmitted to the network device. For example, if the terminal's device identifier is sent via a Non-Access Stratum (NAS) message, the network device does not know the terminal's device identifier.

[0108] Moreover, even if the network device can learn the device identification of the terminal, for example, the network device determines the terminal to be inventoried based on the device identification, but in the cellular network, the network device controls the terminal, rather than the terminal controlling the network device, so the device identification reported by the terminal may not necessarily be applicable to the first service communication between the network device and the terminal after the inventory service.

[0109] In addition, since the inventory service performed by the network device is performed on multiple terminals, for example, terminal #1 has been connected to the network device and can perform the subsequent first communication service, but terminal #2 is still performing the inventory service. If terminal #1 still uses the channel used for the inventory service when performing the first communication service, then interference may occur between terminal #2.

[0110] FIG2A is an interactive schematic diagram showing a communication method according to an embodiment of the present disclosure.

[0111] As shown in FIG2A , the communication method may include the following steps:

[0112] In step S201, the terminal performs first service communication with the network device based on first information.

[0113] In some embodiments, the first information includes a first identifier.

[0114] For example, the first identifier may be determined based on the first indication information sent by the network device, or may be determined based on a protocol agreement, and this disclosure does not limit this.

[0115] According to an embodiment of the present disclosure, a network device may indicate a first identifier to a terminal, or the first identifier may be agreed upon by a protocol, so that the terminal can perform first service communications with the network device based on the first identifier. Based on this, it can be ensured that the first identifier used by the terminal for the first service communications is controlled by the network device or the protocol, rather than being indicated by the terminal to the network device, which is conducive to the first identifier being applicable to the first service communications between the network device and the terminal.

[0116] In some embodiments, the first identifier is used for at least one of the following:

[0117] used for the first service communication between the terminal and the network device, for example, dedicated to the first service communication between the terminal and the network device, and not used for the first service communication between other terminals and the network device;

[0118] Used for each terminal in the terminal group to which the terminal belongs to perform first service communication with the network device;

[0119] Used for each terminal within the coverage area of ​​the network device to perform first service communication with the network device.

[0120] For example, the first identifier may be applicable only to one terminal. The terminal may use the first identifier when communicating with the network device for the first service, for example, for scrambling, indicating the terminal identity, etc. The first identifier may be equivalent to a temporary identity identifier. Other terminals may not use the first identifier when communicating with the network device for the first service.

[0121] For example, the first identifier can be applicable to each terminal in a terminal group. Each terminal in the terminal group uses the first identifier when performing first service communications with the network device, for example, for scrambling, indicating the terminal identity, etc. The first identifier can be equivalent to a temporary identity identifier. Terminals in other groups cannot use the first identifier when performing first service communications with the network device. The present disclosure does not limit the method for determining terminal groups. For example, the agreement stipulates that terminals of the same type constitute a terminal group. For example, the terminal groups can be divided by the network device.

[0122] For example, the first identifier may be applicable to each terminal within the coverage of the network device (for example, in one or more cells corresponding to the network device). Each terminal within the coverage of the network device uses the first identifier when communicating with the network device for the first service, for example, for scrambling, indicating the terminal identity, etc. The first identifier may be equivalent to a temporary identity identifier, such as an RNTI. Terminals outside the coverage of the network device cannot use the first identifier when communicating with the network device for the first service.

[0123] It should be noted that the above three uses of the first identifier may be non-transparent or transparent to the terminal, and the present disclosure does not limit this.

[0124] In some embodiments, the first service includes a command service. The network device performing the command service may include at least one of the following operations: performing a read, write, or kill operation on a terminal. If a first identifier is indicated for the terminal or the first identifier is agreed upon in a protocol, the network device may perform the command service with the terminal based on the first identifier.

[0125] For example, taking the data reading operation as an example, the network device can read data from the terminal, such as reading the information perceived by the terminal. The terminal can scramble the reported data based on the first identifier. The network device can subsequently descramble the received information through the first identifier. If the descrambling is successful, it can be determined to be data read from the first terminal. If the descrambling fails, it is determined that the data is not read from the first terminal and can be discarded.

[0126] In some embodiments, the terminal may perform a second service communication with the network device based on the second information, where the second service includes an inventory service; wherein the second information includes a second identifier, and the second identifier is different from the first identifier.

[0127] In some embodiments, performing the second service communication with the network device includes at least one of the following:

[0128] receiving a first query command sent by a network device;

[0129] Sending a first random number sequence to the network device;

[0130] receiving first confirmation information sent by the network device;

[0131] Sending a second identifier to the network device;

[0132] Receive second confirmation information sent by the network device.

[0133] FIG2B is an interactive schematic diagram showing a communication method according to an embodiment of the present disclosure.

[0134] As shown in FIG2B , before performing an inventory service with a terminal, the network device may first send a Select command to the terminal to select one or more terminals.

[0135] The network device performs an inventory service with the terminal and may send a first query (Query) command to the terminal.

[0136] After receiving the first query command or the repeatedly transmitted first query command (QueryRep), the terminal may send a first random number sequence, such as a 16-bit random number sequence (RN16), to the network device.

[0137] After receiving the RN16 sequence sent by the terminal, the network device may send a first confirmation message (ACK#1) to the terminal if the terminal is allowed to access.

[0138] After receiving the first confirmation information, the terminal may determine that the access is successful, and then may send a second identifier, such as a device identifier (Device ID) of the terminal, to the network device.

[0139] The network device can determine the terminal that has been inventoried based on the device identifier, and can then send a second confirmation message (ACK#2) to the terminal so that the terminal can determine that the network device has received the second identifier.

[0140] In some embodiments, the second confirmation information may or may not carry information required for subsequent communication (e.g., the first communication service). In some embodiments, the second confirmation information may carry information such as the RN16 and / or device identification reported by the terminal, so that the terminal determines that the second confirmation information is sent to the terminal based on the RN16 and / or device identification.

[0141] Based on the above process, it can be seen that the second identifier is the device identifier reported by the terminal during the inventory service of the network device. In order to avoid confusion between the first identifier and the second identifier used in subsequent command services with the network device, the first identifier indicated by the network device to the terminal can be different from the second identifier.

[0142] In some embodiments, the second confirmation information is used to carry the first indication information. That is, the network device can carry the first indication information in the second confirmation information sent to the terminal, thereby indicating the first identifier to the terminal. Of course, the network device can also indicate the first identifier in other ways, and this disclosure is not limited to this.

[0143] In some embodiments, the first query signaling is a first query signaling that is repeatedly transmitted multiple times, wherein the time interval between adjacent repeatedly transmitted first query signalings is used to receive the first indication information, or the first indication information is received after the second service communication.

[0144] Since the terminal does not communicate with the network device during the time interval between adjacent repeated transmissions of the first query signaling, the network device can use this time interval to send the first indication information, so as to complete the sending of the first indication information as soon as possible.

[0145] Of course, the network device may also send the first indication information to the terminal after the first service communication, for example, by carrying the first indication information in the second confirmation information, or sending the first indication information to the terminal after sending the second confirmation information.

[0146] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A .

[0147] FIG2C is an interactive diagram illustrating a communication method according to an embodiment of the present disclosure.

[0148] As shown in FIG2C , the communication method may include the following steps:

[0149] In step S202, the terminal performs first service communication with the network device based on the first information.

[0150] In some embodiments, the first information includes a first channel.

[0151] For example, the first channel may be determined based on an indication from a network device or based on a protocol agreement, and this disclosure does not limit this.

[0152] According to an embodiment of the present disclosure, a network device can indicate a first channel to a terminal, or a first channel can be agreed upon by a protocol, so that the terminal can perform first service communications with the network device based on the first channel. Based on this, it can be ensured that the first channel used by the terminal for the first service communications is controlled by the network device or agreed upon by the protocol, which facilitates the first channel being suitable for the first service communications between the network device and the terminal.

[0153] In some embodiments, the first service includes a command service. The network device performing the command service may include at least one of the following operations: performing a read, write, or kill operation on a terminal. If a first identifier is indicated for the terminal or the first identifier is agreed upon in a protocol, the network device may perform the command service with the terminal based on the first identifier.

[0154] For example, taking the data reading operation as an example, the network device can read data from the terminal, such as reading information perceived by the terminal. The terminal can send data to the network device on the first channel, and the network device can monitor the data sent by the terminal on the first channel.

[0155] In some embodiments, the terminal performs a second service communication with the network device based on the second information, where the second service includes an inventory service; wherein the second information includes a second channel, and the second channel is independent of the first channel.

[0156] In some embodiments, performing the second service communication with the network device includes at least one of the following:

[0157] receiving a first query command sent by a network device;

[0158] Sending a first random number sequence to the network device;

[0159] receiving first confirmation information sent by the network device;

[0160] Sending a second identifier to the network device;

[0161] Receive second confirmation information sent by the network device.

[0162] As shown in FIG2B , before performing an inventory service with a terminal, the network device may first send a selection command to the terminal to select one or more terminals.

[0163] The network device performs an inventory service with the terminal and may send a first query command to the terminal.

[0164] After receiving the first query command or the repeatedly transmitted first query command (QueryRep), the terminal may send a first random number sequence, such as a 16-bit random number sequence (RN16), to the network device.

[0165] After receiving the RN16 sequence sent by the terminal, the network device may send a first confirmation message (ACK#1) to the terminal if the terminal is allowed to access.

[0166] After receiving the first confirmation information, the terminal may determine that the access is successful, and then may send a second identifier, such as a device identifier (Device ID) of the terminal, to the network device.

[0167] The network device can determine the terminal that has been inventoried based on the device identifier, and can then send a second confirmation message (ACK#2) to the terminal so that the terminal can determine that the network device has received the second identifier.

[0168] In some embodiments, the second confirmation information may or may not carry information required for subsequent communication (e.g., the first communication service). In some embodiments, the second confirmation information may carry information such as the RN16 and / or device identification reported by the terminal, so that the terminal determines that the second confirmation information is sent to the terminal based on the RN16 and / or device identification.

[0169] In the above-mentioned inventory service, the terminal can communicate with the network device on the second channel. In order to avoid interference caused by the first channel and the second channel used in subsequent command services with the network device, the first channel can be independent of the second channel. For example, the first channel and the second channel can be different channels.

[0170] In some embodiments, the first channel is independent of the second channel and satisfies at least one of the following:

[0171] The Absolute Radio Frequency Channel Number (ARFCN) of the first channel is independent of the Absolute Radio Frequency Channel Number of the second channel;

[0172] The coding efficiency of the first channel is independent of the coding efficiency of the second channel;

[0173] A scaling factor DR of a reverse link frequency (BLF) of the first channel is independent of a scaling factor of a BLF of the second channel;

[0174] The calibration parameter TRcal of the reverse link frequency BLF of the first channel is independent of the TRcal of the BLF of the second channel.

[0175] For example, the ARFCN of the first channel is independent of the ARFCN of the second channel. Since the ARFCNs of the two channels are different, the frequency domain resources used by the two channels may also be different, thereby enabling differentiation between the two channels.

[0176] For example, BLF = DR / TRcal, where DR is the scaling factor of the BLF and TRcal is a parameter used for verification, such as the length of the portion of the preamble of a query command sent by the network device to the terminal that instructs the terminal to send a chip length check to the network device. By setting different DRs and / or different TRcals for the first and second channels, the BLFs of the first and second channels can be different. Different BLFs can correspond to different channels, thereby distinguishing the first and second channels.

[0177] For example, the coding efficiency M can represent the number of coded symbols representing one bit, and the bit rate = BLF / M. For example, M can be equal to 2, 4, 8, etc. Since different M can correspond to different channels, the first channel and the second channel can be distinguished accordingly.

[0178] In some embodiments, the second confirmation information is used to indicate the first channel. That is, the network device may include indication information indicating the first channel in the second confirmation information sent to the terminal, thereby indicating the first channel to the terminal. Of course, the network device may also indicate the first channel in other ways, and this disclosure is not limited thereto.

[0179] In some embodiments, the first query signaling is a first query signaling that is repeatedly transmitted multiple times, wherein the time interval between adjacent repeatedly transmitted first query signalings is used to receive the first indication information, or the first indication information is received after the second service communication.

[0180] Since the terminal does not communicate with the network device during the time interval between adjacent repeated transmissions of the first query signaling, the network device can use this time interval to send the first indication information, so as to complete the sending of the first indication information as soon as possible.

[0181] Of course, the network device may also send the first indication information to the terminal after the first service communication, for example, by carrying the first indication information in the second confirmation information, or sending the first indication information to the terminal after sending the second confirmation information.

[0182] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2C .

[0183] In a first aspect, embodiments of the present disclosure provide a communication method. Figure 3 is a schematic flow chart illustrating a communication method according to an embodiment of the present disclosure. The communication method illustrated in this embodiment can be executed by a terminal.

[0184] As shown in FIG3 , the communication method may include the following steps:

[0185] In step S301, based on the first information, a first service communication is performed with the network device; wherein the first information includes a first identifier, the first identifier is determined based on the first indication information sent by the network device or based on the protocol agreement; and / or the first information includes a first channel.

[0186] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0187] In some embodiments, the first identifier is used for at least one of the following: for the terminal to perform first service communication with the network device; for each terminal in the terminal group to which the terminal belongs to perform first service communication with the network device; for each terminal within the coverage area of ​​the network device to perform first service communication with the network device.

[0188] In some embodiments, the first transaction comprises a command transaction.

[0189] In some embodiments, the method also includes: based on the second information, communicating a second service with the network device, the second service including an inventory service; wherein the second information includes a second identifier, the second identifier is different from the first identifier; and / or the second information includes a second channel, the second channel is independent of the first channel.

[0190] In some embodiments, conducting a second service communication with a network device includes at least one of the following: receiving a first query command sent by the network device; sending a first random number sequence to the network device; receiving a first confirmation message sent by the network device; sending a second identifier to the network device; and receiving a second confirmation message sent by the network device.

[0191] In some embodiments, the second confirmation information is used to carry the first indication information, and / or the second confirmation information is used to indicate the first channel.

[0192] In some embodiments, the first query signaling is a first query signaling that is repeatedly transmitted multiple times, wherein the time interval between adjacent repeatedly transmitted first query signalings is used to receive the first indication information, or the first indication information is received after the second service communication.

[0193] In some embodiments, the first channel is independent of the second channel and satisfies at least one of the following:

[0194] The absolute wireless channel number of the first channel is independent of the absolute wireless channel number of the second channel;

[0195] The coding efficiency of the first channel is independent of the coding efficiency of the second channel;

[0196] The scaling factor of the reverse link frequency BLF of the first channel is independent of the scaling factor of the BLF of the second channel;

[0197] The calibration parameter TRcal of the reverse link frequency BLF of the first channel is independent of the TRcal of the BLF of the second channel.

[0198] In some embodiments, the network device is a Reader and the terminal is a Device as an example.

[0199] After receiving the Device ID reported by the Device, the Reader carries the corresponding ID in the confirmation message "ACK" (which may be a contention resolution message) for subsequent scheduling (eg, first service communication).

[0200] The information may include the first ID and / or the second ID and / or the third ID;

[0201] For example, the first ID is used to indicate the ID of the current device in subsequent scheduling, or a temporary identity. After receiving the R2D command containing the ID, the device performs corresponding operations, such as Read, Write, Kill, etc.

[0202] For example, the second ID is used to indicate the ID of the device group to which the current device belongs in subsequent scheduling, or a temporary group identity. After receiving the R2D command containing this ID, the device performs corresponding operations, such as Read, Write, Kill, etc.

[0203] For example, the third ID can be configured or specified by the protocol by default to instruct all devices around the current reader (base station or intermediate UE) to perform the operation corresponding to the R2D command. After receiving the R2D command containing the ID, the device performs the corresponding operation, such as Read, Write, Kill, etc.

[0204] Furthermore, the R2D message also includes an ID indicating the identity of the Device, which may be the RN information (N-bit random number) reported by the Device in the previous step, such as step 1, or the AIOT Device ID reported in step 3.

[0205] Subsequent scheduling can be performed within the current random access occasion, or can be initiated independently after the access is completed, independent of the access process.

[0206] For the first aspect and the optional implementation of the optional embodiment of the first aspect, please refer to the optional implementation in the embodiment shown in FIG2A and other related parts in the embodiment involved in FIG2A , which will not be repeated here.

[0207] In a second aspect, embodiments of the present disclosure provide a communication method. Figure 4 is a schematic flow chart illustrating a communication method according to an embodiment of the present disclosure. The communication method illustrated in this embodiment can be executed by a network device.

[0208] As shown in FIG4 , the communication method may include the following steps:

[0209] In step S401, a first service communication is performed with a terminal based on first information; wherein the first information includes a first identifier, the first identifier is indicated by a first indication information sent by a network device or determined based on a protocol agreement; and / or the first information includes a first channel.

[0210] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0211] In some embodiments, the first identifier is used for at least one of the following: for the terminal to perform first service communication with the network device; for each terminal in the terminal group to which the terminal belongs to perform first service communication with the network device; for each terminal within the coverage area of ​​the network device to perform first service communication with the network device.

[0212] In some embodiments, the first transaction comprises a command transaction.

[0213] In some embodiments, the method further includes: based on the second information, conducting a second business communication with the terminal, the second business including an inventory business; wherein the second information includes a second identifier, the second identifier is different from the first identifier; and / or the second information includes a second channel, the second channel is independent of the first channel.

[0214] In some embodiments, performing a second service communication with the terminal includes at least one of the following: sending a first query command to the terminal; receiving a first random number sequence sent by the terminal; sending a first confirmation message to the terminal; receiving a second identifier sent by the terminal; and sending a second confirmation message to the terminal.

[0215] In some embodiments, the second confirmation information is used to carry the first indication information, and / or the second confirmation information is used to indicate the first channel.

[0216] In some embodiments, the first query signaling is a first query signaling that is repeatedly transmitted multiple times, wherein the time interval between adjacent repeatedly transmitted first query signalings is used to receive the first indication information, or the first indication information is received after the second service communication.

[0217] In some embodiments, the first channel is independent of the second channel and satisfies at least one of the following:

[0218] The absolute wireless channel number of the first channel is independent of the absolute wireless channel number of the second channel;

[0219] The coding efficiency of the first channel is independent of the coding efficiency of the second channel;

[0220] The scaling factor of the reverse link frequency BLF of the first channel is independent of the scaling factor of the BLF of the second channel;

[0221] The calibration parameter TRcal of the reverse link frequency BLF of the first channel is independent of the TRcal of the BLF of the second channel.

[0222] In some embodiments, taking the first service communication including the Command service as an example, the D2R response corresponding to the Command service (operations such as reading, writing, and killing one or more devices) uses a D2R channel configured separately from the response of the Inventory service (a service triggered by a reader to allow the device to report the corresponding Device ID).

[0223] For example, the corresponding channel may be separately indicated for the Command, which may be included in the above-mentioned contention resolution message 4 or in the corresponding scheduling Command;

[0224] Accordingly, after receiving the scheduling command, the device sends the corresponding D2R response on the indicated channel;

[0225] Furthermore, this channel has a higher bit rate than the Inventory service (similar to the D2R channel corresponding to the Query signaling received in RFID);

[0226] You can configure a separate DR, DRcal, or M for the D2R channel corresponding to the Command service, where:

[0227] BLF = DR / TRcal, where TRcal is the length of the portion of the Preamble in the downlink Query signaling sent by the reader to the tag, which contains the chip length check sent from the tag to the reader. DR is the scaling factor corresponding to BLF calculated based on TRcal;

[0228] M is the coding efficiency, that is, the number of encoded symbols represents one bit; then the bit rate = BLF / M.

[0229] This method allows a reader (base station or intermediate UE) to separate the inventory service from the command service, preventing channel preemption. The command service does not need to consider the timeline of the inventory service, but can be executed separately and processed in parallel, thereby increasing system efficiency.

[0230] For the second aspect and the optional implementation of the optional embodiment of the second aspect, please refer to the optional implementation in the embodiment shown in FIG2C and other related parts in the embodiment involved in FIG2C , which will not be repeated here.
