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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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).

[0118] In some embodiments, in an Ambient IoT scenario, a passive IoT device can send information based on backscatter. For example, in a mobile network, the passive IoT device can send information to a network device or a terminal. The information sent by the passive IoT device can include data or signaling, and this disclosure does not limit this.

[0119] Because passive IoT devices transmit information based on backscatter, their transmission power is very limited. Therefore, uplink transmission operations such as sending a packet or a transport block (TB) by passive IoT devices require a relatively long duration. In some embodiments, to meet coverage requirements, passive IoT devices need to support time-domain repetition mechanisms at the bit, packet, or transport block levels, which further increases the duration of uplink transmission operations.

[0120] Furthermore, because passive IoT devices are typically equipped with low-cost crystal oscillators for cost-effectiveness, the sampling frequency offset (SFO) can increase over time during continuous uplink transmissions, leading to degraded uplink performance. In this scenario, even if the network allocates uplink time resources to the passive IoT device, it may not be able to use all of the uplink time resources.

[0121] In addition, since passive IoT devices are based on backscatter communication, their communication capabilities are relatively low and the peak power they can provide is limited, so they cannot be accurately synchronized with the system. Therefore, the passive IoT can be regarded as an asynchronous system.

[0122] Due to the above characteristics of passive IoT devices, when passive IoT devices communicate in a mobile network, they differ from traditional terminals (such as mobile phones) communicating in a mobile network in the following ways:

[0123] Traditional terminals and network devices have aligned understandings of communication resources. On the one hand, traditional terminals can achieve synchronization during communication (e.g., uplink synchronization, downlink synchronization), and on the other hand, they can communicate with network devices on the time domain resources configured by the network devices.

[0124] Passive IoT devices and network devices have different understandings of communication resources. On the one hand, passive IoT devices are asynchronous during communication, and on the other hand, they may not be able to communicate with network devices on the time domain resources configured by network devices.

[0125] Therefore, in passive IoT scenarios, it is necessary to ensure that the sending and receiving devices have an aligned understanding of the length of the transmitted information in order to ensure good communication performance between devices.

[0126] FIG2A is an interactive schematic diagram illustrating a method for sending information according to an embodiment of the present disclosure.

[0127] As shown in FIG2A , the information sending method may include the following steps:

[0128] In step S201, the first device sends first information to the second device.

[0129] In some embodiments, end information is provided after the first information. For example, the end information is used to indicate that the transmission of the first information is complete.

[0130] It should be noted that, in some embodiments, the end information may not belong to the first information. For example, the end information may not be separated from the first information by a gap after the channel carrying the first information, or may be separated by a gap of a predefined length. In other embodiments, the end information may belong to the first information. For example, when the end information is a bit sequence, the end information may be the last few bits of the first information (e.g., the first number of bits).

[0131] In step S202, the second device determines that the transmission of the first information is completed according to the end information.

[0132] It should be noted that the first and second devices in the embodiments of the present disclosure can be devices communicating in a passive IoT scenario, but are not limited to such devices. Any device that requires alignment of the length of transmitted information can be applied to the embodiments of the present disclosure. The following mainly illustrates the technical solution of the present disclosure using the first and second devices communicating in a passive IoT scenario.

[0133] In some embodiments, the first device may be a transmitting device in a passive Internet of Things scenario, and the second device may be a receiving device in a passive Internet of Things scenario.

[0134] In some embodiments, the first device is a network device or a terminal, and the second device is a passive Internet of Things device. In this case, the first information may be downlink information.

[0135] In some embodiments, the first device is a passive IoT device, and the second device is a network device or a terminal. In this case, the first information may be uplink information.

[0136] In some embodiments, the passive IoT device can communicate with the terminal. For example, the terminal acts as a reader / writer, and the passive IoT device can act as a tag. The reader / writer can send information to the tag, and the tag can also send information to the reader / writer.

[0137] In some embodiments, the passive IoT device can communicate with the network device. For example, the network device acts as a reader / writer, and the passive IoT device acts as a tag. The reader / writer can send information to the tag, and the tag can also send information to the reader / writer.

[0138] Among them, the passive Internet of Things device can communicate directly with the network device, or the passive Internet of Things device can communicate with the network device indirectly, for example, the passive Internet of Things device can communicate indirectly with the network device through a relay device (such as a terminal).

[0139] FIG2B is a schematic diagram showing end information according to an embodiment of the present disclosure.

[0140] As shown in Figure 2B, the first device can send first information to the second device. For example, the first information includes passive Internet of Things transmission (A-IoT transmission), and end information is set after the first information. For example, the end information can be called end information (end mark) or can be called a postamble.

[0141] In some embodiments, a preamble may be provided before the first information. For details about the preamble, reference may be made to related technologies and will not be elaborated herein.

[0142] According to an embodiment of the present disclosure, since the end information is set after the first information, when the second device recognizes the end information during the process of receiving the first information, it can determine that the transmission of the first information has been completed. Accordingly, it can be ensured that the first device and the second device can align their understanding of the transmission length of the first information based on the end information, so as to ensure good communication performance of the first device and the second device.

[0143] For example, the first device can set an end message after sending the first message to the second device. The second device can determine that the first message has been transmitted based on the end message, and thus can stop receiving the first message, such as stopping monitoring the channel where the first message is located, so as to save power consumption of the second device.

[0144] The end information is exemplified below through several embodiments.

[0145] In some embodiments, the end information includes at least one of the following: a bit sequence; a level sequence.

[0146] In some embodiments, the bit sequence may be agreed upon by a protocol, or may be indicated by a network device.

[0147] In some embodiments, the level sequence may be agreed upon by a protocol, or may be instructed by a network device.

[0148] In some embodiments, the waveform of the bit sequence and / or level sequence may include at least one of the following:

[0149] OOK (On / Off Keying) waveform, ASK (Amplitude-Shift Keying) waveform. It should be understood that these two waveforms are just examples, and the specific waveforms can be expanded as needed and are not limited to these two waveforms.

[0150] In some embodiments, the encoding method of the waveform of the bit sequence and / or level sequence includes at least one of the following:

[0151] PIE (Pulse Interval Encoding) and Manchester encoding. It should be understood that these two encoding methods are just examples, and specific encoding methods can be expanded as needed and are not limited to these two encoding methods.

[0152] In some embodiments, the bit sequence includes at least one of the following:

[0153] a first consecutive number of bits having a value of 0;

[0154] A first number of consecutive bits having a value of 1.

[0155] In some embodiments, the first number may be agreed upon by a protocol, or may be indicated by a network device.

[0156] For example, the first number is 6, and the bit sequence may be 6 consecutive bits with a value of 0, that is, 000000, or the bit sequence may be 6 consecutive bits with a value of 1, that is, 111111.

[0157] It should be noted that the above description of the bit sequence is only an example of a bit sequence. The bit sequence does not need to be a continuous sequence of bits with a value of 0. It only needs to be a bit sequence that is understood by the first and second devices. For example, the bit sequence is 010111. The first device sets this bit sequence after the first message. When the second device recognizes the bit sequence 010111 during the process of receiving the first message, it can determine that the first message has been transmitted.

[0158] In some embodiments, the level sequence includes at least one of the following:

[0159] A first number of consecutive low-level symbols;

[0160] The first continuous duration of low level;

[0161] a first number of consecutive high-level symbols;

[0162] The first continuous duration of high level.

[0163] In some embodiments, the first number may be agreed upon by a protocol, or may be indicated by a network device.

[0164] In some embodiments, the first duration may be agreed upon by a protocol, or may be indicated by a network device.

[0165] For example, the first number is N. Taking the level sequence including N consecutive low-level symbols as an example, the first device can send N consecutive low-level symbols after sending the first information. When the second device recognizes N consecutive low-level symbols during the process of receiving the first information, it can be determined that the first information has been transmitted.

[0166] For example, the first quantity is t. Taking the level sequence including continuous low-level symbols of t duration as an example, after sending the first information, the first device can send a continuous low level of t duration. When the second device recognizes a continuous low level of t duration in the process of receiving the first information, it can determine that the first information has been transmitted.

[0167] In some embodiments, the end information corresponds to at least one of the following:

[0168] a transmission direction of the first information;

[0169] a format of a channel used to carry the first information;

[0170] The business type of the first information;

[0171] The number of repetitions of the first information;

[0172] In some embodiments, there is a corresponding relationship between the end information and the transmission direction of the first information.

[0173] For example, the transmission direction of the first information may include one of the following: uplink and downlink. The end information following the uplink information and the end information following the downlink information may be different. For example, the end information following the uplink information may be end information #0, and the end information following the downlink information may be end information #1. It should be understood that the end information following the uplink information and the end information following the downlink information may also be the same, and the specific setting can be made as needed, and this disclosure does not disclose any limitations.

[0174] For example, if the format of the channel carrying the first information is different, the end information after the first information may also be different. The format of the channel carrying the first information may be related to the type of the first information. For example, if the first information is a 16-bit random number (RN16), the format of the channel carrying the 16-bit random number is format#0, and the format of the channel used to carry other types of first information is format#1, then for these two formats of channels, the end information after the first information carried may be different. For example, the end information after the first information carried by the channel in format#0 is end information#0, and the end information after the first information carried by the channel in format#1 is end information#1.

[0175] For example, the service type (or command type) of the first information includes at least one of the following: selection, inventory, access, contention resolution, and sensor.

[0176] For example, if the service type of the first information is selection, the end information after the first information is end information #0; if the service type of the first information is inventory (such as query (Query) or query request (QueryRep) in inventory), the end information after the first information is end information #1; if the service type of the first information is contention resolution (such as acknowledgment (ACK) in radio frequency identification (RFID)), the end information after the first information is end information #2.

[0177] For example, the number of repeated transmissions of the first information includes one of the following: the last retransmission and the non-last retransmission. When the first information is the non-last retransmission of a transport block (TB), the end information following the first information may be end information #0. The second device may determine that the repeated transmission has ended based on end information #0, but may need to continue receiving repeated transmissions of the transport block. When the first information is the last retransmission of the transport block (TB), the end information following the first information may be end information #1. The second device may determine that the repeated transmissions of subsequent transport blocks have ended based on end information #1.

[0178] Alternatively, the end information may be set after the first information only for the last retransmission of the first information, while the end information may not be set after the first information for the first information not retransmitted for the last time.

[0179] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0180] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0181] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0182] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0183] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2A .

[0184] FIG2C is an interactive diagram illustrating another information sending method according to an embodiment of the present disclosure.

[0185] As shown in FIG2C , the information sending method may include the following steps:

[0186] In step S203, the first device sends first information and first indication information to the second device.

[0187] In some embodiments, the first indication information is used to indicate the length of the first information.

[0188] In step S204, the second device determines the length of the first information according to the first indication information.

[0189] It should be noted that the first and second devices in the embodiments of the present disclosure can be devices communicating in a passive IoT scenario, but are not limited to such devices. Any device that requires alignment of the length of transmitted information can be applied to the embodiments of the present disclosure. The following mainly illustrates the technical solution of the present disclosure using the first and second devices communicating in a passive IoT scenario.

[0190] In some embodiments, the first device may be a transmitting device in a passive Internet of Things scenario, and the second device may be a receiving device in a passive Internet of Things scenario.

[0191] In some embodiments, the first device is a network device or a terminal, and the second device is a passive Internet of Things device. In this case, the first information may be downlink information.

[0192] In some embodiments, the first device is a passive IoT device, and the second device is a network device or a terminal. In this case, the first information may be uplink information.

[0193] In some embodiments, the passive IoT device can communicate with the terminal. For example, the terminal acts as a reader / writer, and the passive IoT device can act as a tag. The reader / writer can send information to the tag, and the tag can also send information to the reader / writer.

[0194] In some embodiments, the passive IoT device can communicate with the network device. For example, the network device acts as a reader / writer, and the passive IoT device acts as a tag. The reader / writer can send information to the tag, and the tag can also send information to the reader / writer.

[0195] Among them, the passive Internet of Things device can communicate directly with the network device, or the passive Internet of Things device can communicate with the network device indirectly, for example, the passive Internet of Things device can communicate indirectly with the network device through a relay device (such as a terminal).

[0196] According to an embodiment of the present disclosure, the first device indicates the length of the first information through the first indication information, and the second device can determine the length of the first information based on the first indication information. Therefore, in the process of receiving the first information, after determining that the first information reaches the length indicated by the first indication information, it can be determined that the transmission of the first information is completed. Accordingly, it can be ensured that the first device and the second device can align their understanding of the transmission length of the first information based on the end information, so as to ensure good communication performance of the first device and the second device.

[0197] For example, when the first device sends the first information to the second device, it can also send the first indication information to the second device. The second device can determine the length of the first information based on the first indication information. Therefore, in the process of receiving the first information, after determining that the first information reaches the length indicated by the first indication information, it can be determined that the first information has been transmitted. Therefore, it can stop receiving the first information, for example, stop monitoring the channel where the first information is located, so as to save power consumption of the second device.

[0198] In some embodiments, the length comprises at least one of: a time length; a bit length (eg, a first number of bits).

[0199] In some embodiments, the time length includes at least one of the following: seconds (s), milliseconds (ms), time slots (slots), and symbols (symbols).

[0200] Taking the example that the length of the first information includes n symbols, the second device can determine that the length of the first information is n symbols based on the first indication information. Then, in the process of receiving the first information, when the second device determines that the first information lasts for n symbols from the start time, it can be determined that the first information has been transmitted.

[0201] Taking the example that the length of the first information includes m bits, the second device can determine that the length of the first information is m bits based on the first indication information. Then, in the process of receiving the first information, when the second device determines that the first information continues for m bits starting from the starting bit, it can be determined that the first information has been transmitted.

[0202] It should be noted that, regarding the method of determining the start time and start bit of the first information, reference can be made to related technologies, for example, it can be determined based on the preamble before the first information, and the present disclosure does not limit this.

[0203] In some embodiments, the first indication information is carried in at least one of the following:

[0204] The header of the first message;

[0205] A preamble preceding the first message.

[0206] For example, the first indication information may be carried in the header of the first information. For example, a new information field may be provided in the header of the first information, and the new information field may serve as the first indication information. Alternatively, idle bits in the information field in the header of the first information may serve as the first indication information. The header of the first information may refer to a relatively front portion of bits in the first information, such as the first k (which may be a value specified by the protocol or indicated by the network device) bits in the first information.

[0207] By carrying the first indication information in the header of the first information, the second device can first receive the header of the first information when receiving the first information, thereby obtaining the first indication information, so as to determine the length of the first information before the reception of the first information is completed.

[0208] For example, the first indication information may be carried in a preamble preceding the first information. For example, the last few bits of the preamble may be used as the first indication information.

[0209] By carrying the first indication information in the preamble of the first information, it is possible to ensure that the second device receives the preamble of the first information before receiving the first information, thereby obtaining the first indication information, so as to determine the length of the first information before the first information is received.

[0210] FIG2D is a schematic diagram showing first indication information according to an embodiment of the present disclosure.

[0211] As shown in Figure 2D, a first device may send a first message to a second device. For example, the first message includes an A-IoT transmission, and a header of the first message includes first indication information. When receiving the first message, the second device may first receive the header of the first message, thereby obtaining the first indication information, so as to determine the length of the first message before completing reception of the first message.

[0212] In some embodiments, a preamble may be provided before the first information. For details about the preamble, reference may be made to related technologies and will not be elaborated herein.

[0213] In some embodiments, the position and / or length of the first indication information in the header of the first information is agreed upon by the protocol or indicated by the network; or, the position and / or length of the first indication information in the preamble code is agreed upon by the protocol or indicated by the network.

[0214] For example, if the first indication information is in the header of the first information, then the position and / or length of the first indication information in the header of the first information is agreed upon by the protocol or indicated by the network. Accordingly, it can be ensured that the first device and the second device have an aligned understanding of the position and / or length of the first indication information in the header of the first information, and that the second device can correctly parse the first indication information according to the position and / or length of the first indication information in the header of the first information, thereby correctly determining the length of the first information indicated by the first indication information.

[0215] For example, if the first indication information is in the preamble of the first information, then the position and / or length of the first indication information in the preamble is agreed upon by the protocol or indicated by the network. Accordingly, it can be ensured that the first device and the second device have an aligned understanding of the position and / or length of the first indication information in the preamble, and that the second device can correctly parse the first indication information according to the position and / or length of the first indication information in the preamble, thereby correctly determining the length of the first information indicated by the first indication information.

[0216] In some embodiments, the type of the first indication information includes at least one of the following: explicit indication information; implicit indication information.

[0217] The first device may send the first indication information to the second device in an explicit manner or in an implicit manner.

[0218] For example, taking the type of the first indication information as display indication information as an example, the first device may add the first indication information to the header or preamble of the first information to explicitly indicate the length of the first information.

[0219] For example, taking the type of the first indication information as implicit indication information as an example, the first indication information includes at least one of the following:

[0220] signaling in the first information, wherein the signaling corresponds to a length of the first information;

[0221] a format of a channel used to carry the first information, wherein the format of the channel corresponds to the length of the first information;

[0222] a service type of the first information, wherein the service type corresponds to the length of the first information;

[0223] The number of repeated transmissions of the first information corresponds to the length of the first information.

[0224] In some embodiments, the first indication information may include signaling in the first information, and the signaling may correspond to the length of the first information. The mapping relationship between the signaling and the length of the first information may be a protocol agreement or an indication of a network device.

[0225] For example, the first information carries signaling. When the second device receives the first information, for example, if the signaling in the first information is signaling #0, it can determine that the length of the first information is length #0; if the signaling in the first information is signaling #1, it can determine that the length of the first information is length #1.

[0226] In some embodiments, the first indication information may include a format of a channel used to carry the first information, and the format of the channel used to carry the first information may correspond to the length of the first information. The mapping relationship between the format of the channel used to carry the first information and the length of the first information may be a protocol agreement or an indication of a network device.

[0227] For example, when the second device is receiving the first information, it can determine the format of the channel used to carry the first information, for example, determine that the format of the channel used to carry the first information is format#0, determine that the length of the first information is length#0, determine that the format of the channel used to carry the first information is format#1, and determine that the length of the first information is length#1.

[0228] In some embodiments, the first indication information may include a service type of the first information, and the service type may correspond to the length of the first information. The mapping relationship between the service type and the length of the first information may be a protocol agreement or an indication of a network device.

[0229] For example, when the second device is receiving the first information, it can determine the business type of the first information, for example, determine that the business type of the first information is inventory, determine that the length of the first information is length #0, determine that the signaling in the first information is sensor, and determine that the length of the first information is length #1.

[0230] In some embodiments, the first indication information may include a number of repetitions of the first information, and the number of repetitions may correspond to the length of the first information. The mapping relationship between the number of repetitions and the length of the first information may be a protocol agreement or an indication of a network device.

[0231] For example, when the second device is receiving the repeatedly transmitted first information, it can determine the repeated transmission of the currently received first information. For example, if the determined number of repeated transmissions is not the last transmission, the length of the first information can be determined to be length #0. If the determined number of repeated transmissions is the last transmission, the length of the first information can be determined to be length #1.

[0232] The communication method involved in the embodiment of the present disclosure may include at least one of steps S203 to S204. For example, step S203 may be implemented as an independent embodiment, step S204 may be implemented as an independent embodiment, and steps S203+S204 may be implemented as independent embodiments, but are not limited thereto.

[0233] In some embodiments, steps S203 and S204 may be performed in an interchangeable order or simultaneously.

[0234] In some embodiments, step S203 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0235] In some embodiments, step S204 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
