[0154] 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.

[0155] In related technologies, Ambient-IoT terminals may or may not have power devices. Terminals with power devices are called active terminals, while those without are called passive terminals. Passive terminals are characterized by being powered by other devices or natural conditions, requiring no human maintenance. Active terminals may contain a small amount of energy storage devices, such as capacitors, to provide energy for communications.

[0156] The convenience of Ambient-IoT terminals has led to a massive number of them. To enable querying Ambient-IoT terminals, Ambient-IoT coding is essential. There are two potential approaches to Ambient-IoT coding: one is to continue the existing variable barcode + sequence code design, or the other is to replace portions of the variable barcode and / or sequence code with a cell ID, etc., through a base station or other device to create a fused code. The first approach requires redefining the code field information contained in the variable barcode to adapt it to existing communication systems. This type of coding uniquely encodes all items using a large number of coding bits. It is simple and straightforward, backed by mature technology. However, the required signaling overhead is relatively high, and longer-distance transmission can reduce transmission efficiency. The second approach, based on the existing NR cell ID design, can introduce the cell ID into the code, replacing some of the coding information and compressing the code overall. This type of coding requires a more complex design.

[0157] The potential design principles of Ambient-IoT coding include: large coding capacity; consideration of compatibility with existing coding technologies (interconversion with ECP); minimal overhead; support for multiple indication / overwrite methods, or interconversion between multiple methods; strong versatility and applicability to various industries; and standardization and compliance with laws and regulations across countries.

As shown in FIG2a , the method for indicating encoding code domain information according to an embodiment of the present disclosure is executed by a terminal, and the method includes:

[0159] Step S2101: determine first indication information.

[0161] In some embodiments, the first device 102 sends first indication information.

[0162] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0163] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0164] In some embodiments, the first indication information is used to indicate the encoding code domain information of the encoding codeword corresponding to the terminal 101. The terminal 101 is encoded by the encoding codeword to distinguish each terminal, wherein the encoding code domain information is used to refer to the encoding code domain information indicated by the encoding codeword on each field in the encoding codeword. For example, the encoding codeword of the terminal 101 is the number 110100, and the encoding code domain information of the terminal is: the first three encoding codewords represent the codebook type, and the last three encoding codewords represent the encoding version number. Then, the codebook type in the encoding codeword corresponding to the terminal 101 is 110, and the encoding version number is 100. The encoding code domain information of the encoding codeword corresponding to the terminal 101 is based on the set encoding rule of the encoding codeword, and may include one or more, and may be set according to the encoding requirements of the terminal 101.

[0165] In some embodiments, the name of the first indication information is not limited, and it can be, for example, "code domain information", "codeword type information", "encoded codeword type information", "codeword classification information", etc.

[0166] In some embodiments, the terms "codebook," "codeword," and "precoding matrix" may be used interchangeably. For example, a codebook may be a collection of one or more codewords / precoding matrices.

[0167] In some embodiments, the first indication information includes an encoding codeword. While indicating the encoding code domain information of the terminal 101 based on the first indication information, the encoding codeword of the terminal 101 can be indicated according to the first indication information at the same time, so as to reduce the number of interactions and save communication overhead.

[0168] In some embodiments, the encoding codeword is used to indicate the encoding of terminal 101.

[0169] In some embodiments, the name of the encoding codeword is not limited, and it can be, for example, "encoding information", "terminal number information", "terminal identity information", etc.

[0170] In some embodiments, the terminal includes an Internet of Things device. For example, the Internet of Things device may be an Ambient-IoT device.

[0171] In some embodiments, the encoding codeword includes at least one of digital information, character information, string information, and letter information. For example, in this embodiment, to increase the richness of the encoding codeword to meet the large-capacity encoding requirements of terminal 101, digital information, character information, string information, letter information, and other methods can be combined as the encoding codeword of terminal 101. The encoding codeword of terminal 101 can be a single symbol type or a combination of multiple symbol types.

[0173] In some embodiments, the method further comprises: determining a coding overhead of the encoded codeword according to protocol predefined information.

[0174] The protocol predefined information is a communication protocol pre-configured in terminal 101. During the encoding configuration process for terminal 101, the protocol predefined information is read to determine the encoding overhead of the encoding codeword. The encoding overhead can be the bit size occupied by the encoding codeword, with candidate options being 16 / 32 / 48 / 64 / 96 / 128 / 256 / 512, etc.

[0175] In some embodiments, the method further includes: determining a coding overhead for encoding the code domain information based on protocol predefined information.

[0176] The protocol predefined information is a communication protocol preconfigured in terminal 101. During the encoding configuration process for terminal 101, the protocol predefined information is read to determine the encoding overhead of the encoded code domain information. The encoding overhead can be the bit size occupied by the encoded code domain information, with candidate options being 16 / 32 / 48 / 64 / 96 / 128 / 256 / 512, etc.

[0177] In some embodiments, the encoding code domain information includes multiple encoding code domain information, and the method further includes: determining multiple sequence bit information corresponding to the multiple encoding code domain information in the encoding codeword according to protocol predefined information.

[0178] When the first indication information indicates one encoding code field information, the encoding codeword of terminal 101 represents the encoding under the encoding code field information. When the first indication information indicates multiple encoding code field information, to avoid confusion in the encoding codeword caused by the multiple encoding code field information, it is necessary to indicate the encoding bits indicated by the multiple encoding code field information so as to identify the different encoding code field information indicated by each sequence bit of the encoding codeword information. In this embodiment, based on the predefined information of the protocol, multiple sequence bit information corresponding to the multiple encoding code field information in the encoding codeword is determined to indicate the encoding code field represented by each sequence bit in the encoding codeword. For example, according to the predefined information of the protocol, in the encoding codeword, the encoding code domain information indicated by the 1-3 sequence bits is the codebook type; the encoding code domain information indicated by the 4-7 sequence bits is the domain name manager; the encoding code domain information indicated by the 8-10 sequence bits is the item type. Then, when the encoding codeword of the terminal 101 is: 10234A7789, the codebook type number of the terminal 101 is 102, the domain name manager number is 34A, and the item type number is 7789.

[0179] In some embodiments, the first indication information includes encoding mode information.

[0180] In some embodiments, the encoding mode information is used to indicate one or more of the following: a method for modifying the encoding code field information and / or a method for modifying the encoding codeword. For example, in this embodiment, based on the encoding codeword and / or encoding code field information indicated in the first indication information, the historical encoding codeword and / or historical encoding code field information set in the terminal 101 is modified, wherein the first indication information includes the encoding mode information, and the encoding mode information is used to indicate a method for modifying the historical encoding codeword and / or historical encoding code field information in the terminal 101.

[0181] Optionally, in some embodiments, the encoding mode information includes one or more of the following: static encoding, semi-static encoding, or dynamic encoding;

[0182] Static coding is used to indicate that the coding code domain information and / or coding codeword remain unchanged during the life cycle;

[0183] The semi-static coding is used to instruct the first device to modify the coding code domain information and / or coding codeword through radio frequency rewrite signaling or semi-static configuration signaling;

[0184] Dynamic coding is used to instruct the first device to modify the coding code domain information and / or coding codeword through dynamic signaling.

[0185] For example, encoding methods can be divided into three categories from a configuration perspective: static encoding, semi-static encoding, and dynamic encoding. When a static encoding tag is used to modify the encoding codeword and / or encoding code domain, the encoding codeword or encoding code domain remains unique throughout the life cycle of terminal 101, or remains unique within a predefined life cycle of terminal 101.

[0186] When modifying the encoding codeword and / or encoding code domain of a tag using semi-static encoding, the encoding codeword and / or encoding code domain can be modified by using a base station or reader through radio frequency rewriting signaling or semi-static signaling configuration.

[0187] When modifying the encoding codeword and / or encoding code domain using a dynamic encoding tag, it is necessary to respond to the dynamic signaling sent by the base station at any time or periodically to complete the dynamic update of the encoding codeword and / or encoding code domain.

[0188] In some embodiments, the name of the encoding mode information is not limited, and it can be, for example, "encoding method information", "encoding modification mode information", "encoding change mode information", "encoding mode information", etc.

[0189] Through the above method, the modification method of the encoding codeword and / or encoding code domain is indicated in the indication information based on different encoding modification requirements, so that the effective period of the encoding codeword and / or encoding code domain information is indicated by different modification methods, which adapts to the encoding requirements of large-scale Ambient-IoT terminals.

As shown in Figure 2b, in this embodiment, the first device can be a base station. The base station and terminal 101 are directly connected, and both parties can communicate uplink and downlink. Based on this communication mode, the base station sends first indication information to terminal 101 via downlink signaling to indicate the encoding code domain information.

Among them, the intermediate node device can be a relay UE, a relay Ambient-IoT terminal, an intermediate node base station, or other devices used for signaling transmission.

[0203] Optionally, the first device includes an auxiliary node device, the first indication information is sent by the base station to the auxiliary node device through a downlink, and the auxiliary node device sends the first indication information to the terminal through a downlink.

[0204] For example, Figure 2d is a schematic diagram of a networking mode for an Ambient-IoT terminal according to an exemplary embodiment. As shown in Figure 2d, in this embodiment, the first device can be an auxiliary node device. The base station is connected to the auxiliary node device, and the two communicate downlink.

The base station sends the first indication information to the auxiliary node device via a downlink, and the auxiliary node device sends the first indication information to terminal 101 via a downlink.

[0205] Optionally, the first device includes a terminal or a read-write device, and the first indication information is sent by the terminal or the read-write device to the terminal via a downlink.

[0206] For example, Figure 2e is a schematic diagram of a networking mode of an Ambient-IoT terminal according to an exemplary embodiment. As shown in Figure 2e, in this embodiment, the first device can be a terminal or a read-write device, which is connected to the terminal 101, and the two perform uplink and downlink communication.
