Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a resource acquisition, indication method, apparatus, environmental Internet of Things device, and reader. Background Technology

[0003] Currently, all Internet of Things (IoT) devices are powered by batteries, requiring regular charging or battery replacement, resulting in significant manpower and material costs. To further reduce the cost of IoT devices and expand their application scope, a new device type has been redefined: Ambient-Internet of Things (A-IoT). A-IoT devices have little or no energy storage capacity, relying on environmental factors such as wind, solar, pressure, and wireless signals to obtain energy, and are characterized by low energy consumption, low cost, and low complexity.

[0004] Unlike New Radio (NR) User Equipment (UE), which actively initiates random access, A-IoT devices require base station-triggered random access. Currently, the random access process includes two signaling flows: two-step A-IoT random access and three-step A-IoT random access. For three-step random access, how to implement message 3 (Msg3) transmission by the A-IoT device is a pressing issue that needs to be addressed. Summary of the Invention

[0043] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0044] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] I. Types of Ambient-Internet of Things (A-IoT) Devices

[0046] Based on power consumption and performance, A-IoT devices are divided into the following two categories:

[0047] 1. A-IoT Device Type 1: Peak power consumption is approximately 1μW. It lacks signal amplification capabilities in both Reader-to-Device (R2D) signal reception and Device-to-Reader (D2R) signal transmission; D2R signal transmission requires backscattering of an externally provided carrier signal.

[0048] 2. A-IoT Device Type 2: Peak power consumption ≤ hundreds of μW. It possesses signal amplification capabilities during R2D signal reception and / or D2R signal transmission; it achieves D2R signal transmission by independently generating signals or by backscattering externally provided carrier signals. Devices lacking independent signal generation capabilities are classified as A-IoT Device Type 2a, while those possessing independent signal generation capabilities are designated as A-IoT Device Type 2b.

[0049] II. Backscatter Communication

[0050] Backscatter communication systems typically consist of a reader with radio frequency (RF) capability and a tag without RF capability. The reader sends RF signals to the tag; the electromagnetic waves from these signals reach the tag's antenna surface and are reflected back, forming the backscatter signal. By changing the antenna's load impedance, the tag can control the amplitude, waveform, and frequency of the backscatter signal, thereby modulating information onto the backscatter signal. The relationship between the reflected signal and the excitation signal can be expressed as: S out =S in ×Γ i

[0051] Among them, S out For the reflected signal, S in As an excitation signal, Z is the reflection coefficient. i Z is the load impedance. a Γ represents the antenna impedance. i When Γ = 0, the energy of the excitation signal is completely absorbed by the tag antenna; i When the backscattering coefficient is not equal to 0, part of the excitation signal is absorbed and part is reflected. Different modulation symbols correspond to different backscattering coefficients. The reader receives and reads the backscattered signal from the tag to determine the information transmitted by the tag.

[0052] III. Random Access of A-IoT Devices

[0053] The random access process for A-IoT devices can include a 3-step random access signaling process and a 2-step random access signaling process.

[0054] 1. Signaling process for random access in 3 steps:

[0055] A-IoT Message 1 (Msg1): The A-IoT device sends a randomly generated ID to the reader;

[0056] A-IoT Message 2 (Msg2): The reader sends the ID received in Msg1 to the A-IoT device;

[0057] A-IoT Message 3 (Msg3): The A-IoT device sends the device ID and / or other data to the reader according to the requirements of the higher layer. Msg3 is the D2R transmission message that corresponds to Msg2 and is scheduled by Msg2.

[0058] 2. Signaling process for two-step random access:

[0059] A-IoT Msg1: The A-IoT device sends its device ID and / or other data to the reader according to the requirements of the higher layer.

[0060] A-IoT Msg2: The reader will repeatedly send some of the information obtained from Msg1 to the A-IoT device.

[0061] IV. New Radio (NR) Random Access Procedure

[0062] In the NR random access procedure, the transmission resources of Msg3 are scheduled by Msg2 with an uplink grant (UL grant) containing a Random Access Response (RAR). The RAR UL grant includes resource allocation fields, which consist of time-domain and frequency-domain resource allocation fields.

[0063] The time-domain resource allocation field occupies 4 bits and indicates a row index corresponding to a row in the time-domain resource allocation table pre-configured by the base station through Radio Resource Control (RRC) signaling. Each row in this table corresponds to a Start and Length Indicator Value (SLIV) parameter, which the User Equipment (UE) uses to determine the time-domain resources used to transmit Msg3. The frequency-domain resource allocation field occupies 14 bits and indicates the Resource Indicator Value (RIV), including the location of the starting resource block (RB) and the number of RBs occupied by Msg3.

[0064] V. Radio Frequency Identification (RFID)

[0065] After the random access procedure begins, the reader sends a QueryRep command to decrement the counters of each tag by 1. Tags whose counters reach 0 will send an RN16 (a 16-bit random identifier). If the reader successfully receives the RN16, it sends an Acknowledgement (ACK) command carrying the RN16. Upon receiving the ACK, the tag sends its Electronic Product Code (EPC) to the reader, completing the random access. The reader then sends the next QueryRep command to continue counting other tags.

[0066] The embodiments of this disclosure are described below with reference to the accompanying drawings. The resource acquisition, indication method, apparatus, environmental IoT device, and reader provided in the embodiments of this disclosure can be applied to wireless communication systems. This wireless communication system can be a system employing fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system), or a system employing sixth-generation (e.g., 6G) communication technology. Those skilled in the art will understand that the 5G NR system is merely an example and not intended to limit the scope of the invention.

[0067] The technical solutions provided in this disclosure are applicable to a variety of systems, especially 5G systems. For example, applicable systems may include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminals (also called terminal devices, or readers acting as intermediate nodes communicating with IoT devices in the environment) and network devices (e.g., readers). The system may also include a core network component, such as the Evolved Packet System (EPS) or the 5G system (5GS).

[0068] The terminal involved in the embodiments of this disclosure, also referred to as a terminal device, can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal device may differ in different systems; for example, in a 5G system, the terminal device can be called User Equipment (UE).

The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments disclosed herein.

[0069] The network device disclosed in this embodiment may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network equipment involved in this disclosure can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA) system, a NodeB in a wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in this disclosure. In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.

[0070] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D MIMO, 3D MIMO, Full Dimension MIMO (FD-MIMO), or Massive MIMO, or it can be diversity transmission, pre-coded transmission, or beamforming transmission, etc.

[0071] In some embodiments, the structure of a network system to which this disclosure applies includes user equipment, a base station, and environmental IoT devices (also referred to as AIoT devices); or, a base station and environmental IoT devices. The user equipment (UE) can be, for example, a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), or wearable device, etc. It should be noted that the user equipment mentioned in this disclosure mainly refers to user equipment capable of supporting AIoT services, i.e., capable of communicating with environmental IoT devices as a reader. The base station mentioned above can also refer to a base station capable of supporting AIoT services, for example, a base station with reader functionality or an AIoT base station. This base station can be a 5G or later version base station (e.g., gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that this disclosure only uses a 5G base station as an example, but does not limit the specific type of base station.

[0072] This disclosure provides a resource acquisition, indication method, apparatus, environmental IoT device, and reader to ensure that A-IoT devices can successfully transmit randomly accessed message 3 and guarantee communication reliability.

[0073] As shown in Figure 1, this embodiment of the present disclosure provides a resource acquisition method, executed by an A-IoT device, including:

[0074] Step S101: Obtain target information;

[0075] Step S102: Determine the transmission resources for sending message three based on the target information.

[0076] It should be noted that, in this embodiment of the disclosure, the transmission resources for sending message three are determined based on the target information, thereby ensuring that the A-IoT device can successfully transmit message three through random access and guaranteeing communication reliability.

[0077] It should be noted that, in this embodiment of the disclosure, message three refers to message three in the random access process.

[0078] In some embodiments, the transmission resources for sending message 3 (Msg3) can also be understood as the transmission resources for sending the device-to-reader (D2R) signal carrying message 3.

[0079] In some embodiments, one implementation method includes obtaining target information, including:

[0080] Obtain target information through reader pre-configuration and / or through target messages sent by the reader;

[0081] The target message includes at least one of the following: a message that triggers random access, and message two.

[0082] It should be noted that reader pre-configuration can be understood as configuration through pre-configuration messages sent by the reader. These pre-configuration messages are different from random access-related messages. For example, these pre-configuration messages can be Radio Resource Control (RRC) messages.

[0083] It should be noted that the message triggering random access can be sent via a first signal, i.e., the first signal is a reader-to-device (R2D) signal carrying the triggering of random access. In other words, in this embodiment of the disclosure, the description of the message triggering random access can be replaced with the first signal. Message two can be sent via a second signal, i.e., the second signal is an R2D signal carrying message two; in other words, in this embodiment of the disclosure, the description of message two can be replaced with the second signal.

[0084] It should be noted that message two recorded in this embodiment can be understood as message two in a random access procedure (e.g., initiating a random access procedure using a contention-based access method). Message three recorded in this embodiment can be understood as message three in a random access procedure (e.g., initiating a random access procedure using a contention-based access method). Furthermore, in this embodiment, the A-IoT device can also initiate a random access procedure using a non-contention-based access method. Therefore, when the A-IoT device initiates a random access procedure using a non-contention-based access method, message two recorded in this embodiment can be understood as a paging message in the random access procedure using a non-contention-based access method; message three recorded in this embodiment can be understood as a D2R signal sent after receiving the paging message in the random access procedure using a non-contention-based access method; or message one (Msg1) sent in the random access procedure using a non-contention-based access method.

[0085] In some embodiments, the target information includes at least one of A11-A15:

[0086] A11. Time-domain information of transmitted resources;

[0087] A12, Frequency domain information of transmission resources;

[0088] A13, A-IoT device identifier;

[0089] A14. Transmit resource collection information;

[0090] A15, Index Information;

[0091] The index information includes at least one of A151-A154:

[0092] A151, Transmission Resource Index;

[0093] A152, The index of the transmission resource in the transmission resource set;

[0095] A154. Index of a transmission resource in a transmission resource group, wherein the transmission resource group includes a portion of the transmission resources in the transmission resource set.

[0096] The different implementations of the embodiments of this disclosure are described in detail below.

[0097] Implementation scenario 1: Obtain target information through pre-configured and / or triggered random access messages.

[0098] In some embodiments, the target information in this case includes at least one of the following: time-domain information of the transmission resource and frequency-domain information of the transmission resource.

[0099] In some embodiments, the time-domain information of the transmission resource includes at least one of the following:

[0100] B101, Start Time;

[0101] B102, the time-domain offset value at the start time;

[0102] B103, Time Domain Length Information.

[0103] In some embodiments, the time-domain information and / or frequency-domain information included in the target information can be configured by the reader pre-configuration and / or by the message configuration that triggers random access. Specific methods include, but are not limited to, the following:

[0104] For example, one of the time-domain length information, the time-domain offset value at the start time, and the frequency-domain information of the transmission resources is pre-configured by the reader, while the other two are indicated by a message that triggers random access; for example, two of the time-domain length information, the time-domain offset value at the start time, and the frequency-domain information of the transmission resources are pre-configured by the reader, while the other one is indicated by a message that triggers random access; for example, all the information in the time-domain length information, the time-domain offset value at the start time, and the frequency-domain information of the transmission resources is pre-configured by the reader; for example, all the information in the time-domain length information, the time-domain offset value at the start time, and the frequency-domain information of the transmission resources is indicated by a message that triggers random access.

[0105] In some embodiments, under one implementation, the time-domain offset value at the start time includes:

[0106] The time-domain offset of the starting time relative to the first target time.

[0107] In some embodiments, the time-domain offset value can be a single numerical value or a range of values.

[0108] The first target time includes at least one of the following:

[0109] B11, the end time of the message listening window;

[0110] B12, the end time of message two containing the A-IoT device identifier;

[0111] In some embodiments, the message two listening window refers to the message two listening window corresponding to the AIoT device.

[0112] It should be noted that message two containing the A-IoT device identifier can be understood as message two specifically for that A-IoT device; for example, if message two contains the identifier of A-IoT device A and message two contains the identifier of A-IoT device B, then for A-IoT device A, this item gives the time domain offset value of the start time of the transmission resource of message three of A-IoT device A relative to the end time of the listening window of message two containing the identifier of A-IoT device A.

[0113] B13, the end time of the message that triggered random access;

[0114] B14. The end time of the A-IoT device sending message one;

[0115] It should be noted that the end time in this case refers to message one sent by the A-IoT device. For example, for A-IoT device C, this item gives the time-domain offset value of the start time of the transmission resources of message three of A-IoT device C relative to the end time of message one sent by A-IoT device C.

[0116] In some embodiments, the time-domain length information of the transmission resource includes at least one of the following:

[0118] For example, the encoding information may include, but is not limited to, at least one of the following: whether line code is used, line code encoding method, whether channel coding is used, channel coding method, code rate, and number of repeated transmissions.

[0119] B22, the transmission resource duration of message three;

[0120] In some implementations, the transmission resource duration can be seconds, symbols, OFDM symbols, time slots, mini-time slots, etc.

[0121] In some embodiments, the frequency domain information of the transmission resource includes at least one of the following:

[0122] B31, the sending frequency of message three;

[0123] B32, the sub-channel index corresponding to the transmission frequency of message three;

[0124] For example, the reader is pre-configured with 8 sub-channels, with sub-channel indices from 0 to 8. If the sub-channel index is 3, then the frequency domain information of the transmission resources of message 3 corresponds to the sub-channel with sub-channel index 3.

[0125] B33, the frequency shift value of message three relative to message one;

[0126] For example, if the transmission frequency of message one is 900MHz, and the pre-configured transmission frequency of message three is shifted by 0.1MHz relative to the frequency of message one, then the transmission frequency of message three is 900.1MHz.

[0127] B34, Frequency shift value of message three relative to the carrier;

[0128] For example, if the carrier frequency is 900MHz and the shift value of the transmission frequency of pre-configured message three relative to the carrier frequency is 0.1MHz, then the transmission frequency of message three is 900.1MHz.

[0129] B35. Square wave frequency used for square wave modulation to realize three-frequency shifting of messages;

[0130] For example, if the carrier frequency is 900MHz, and the square wave frequency of the square wave modulation used to implement the frequency shift of message three is R times the information bit transmission rate, then the transmission frequency of message three is 9 × 10⁻⁶. 8 +R / T b (Hz), where T b The time length for each information bit.

[0131] B36. The number of times the repeated encoding is used to implement the message three-frequency shift;

[0132] For example, if the carrier frequency is 900MHz, and the message indication that triggers random access uses K repetition codes to implement the frequency shift of message three, then the transmission frequency of message three is 9 × 10⁻⁶. 8 +K / T b (Hz).

[0133] B37, Frequency factor used to implement three-frequency shifting of messages;

[0134] It should be noted that this situation refers to the frequency factor for the frequency shift of message three in the A-IoT device. Based on this frequency factor, the frequency shift value of message three can be determined, and thus the transmission frequency of message three can be determined.

[0135] Implementation scenario two: Obtain target information through pre-configuration and / or message two.

[0136] In some embodiments, the target information in this case includes at least one of the following: time-domain information of the transmission resource, frequency-domain information of the transmission resource, and A-IoT device identifier.

[0137] In some embodiments, the A-IoT device identifier, time-domain information, and / or frequency-domain information included in the target information can be pre-configured by the reader and / or configured by message two.

[0138] For example, one of the A-IoT device identifier, the time-domain information of the transmission resource, and the frequency-domain information of the transmission resource is pre-configured by the reader, and the other two are indicated by message two; for example, two of the A-IoT device identifier, the time-domain information of the transmission resource, and the frequency-domain information of the transmission resource are pre-configured by the reader, and the other one is indicated by message two; for example, all the information in the A-IoT device identifier, the time-domain information of the transmission resource, and the frequency-domain information of the transmission resource is indicated by message two.

[0139] In some embodiments, the A-IoT device identifier may be, for example, a random identifier generated by the device or a portion of its bits.

[0140] In some embodiments, the time-domain information of the transmission resource includes at least one of the following:

[0141] C11, Start time;

[0142] C12, the time-domain offset value at the start time;

[0143] The time-domain offset value of the starting time includes the offset value between the starting time and the second target time. The second target time includes at least one of the following: the end time of the message two listening window, the end time of message two containing the A-IoT device identifier, the end time of the last message two listening window in Y message two listening windows, the end time of the A-IoT device sending message one, the end time of the message that triggers random access, and the end time of the transmission resource of the last message one among X message one transmission resources, where X and Y are integers greater than or equal to 1.

[0144] C13, Time Domain Length Information.

[0145] In some embodiments, the time-domain length information includes at least one of the following:

[0146] C131, Message Three-Code Information;

[0158] Implementation scenario three: Obtain target information through pre-configured, randomly accessed messages and / or message two.

[0159] In some embodiments, the target information in this case includes at least one of the following: transmission resource set information and index information.

[0160] In some embodiments, the transmission resource set information and / or index information included in the target information can be configured by the reader pre-configuration, the message that triggers random access, and / or message two.

[0161] For example, some information in the transmission resource set information is pre-configured by the reader, while another part of the information is indicated by the message that triggers random access, and the index information is indicated by message two; for example, the transmission resource set information is indicated by the message that triggers random access, and the index information is indicated by message two.

[0162] In some embodiments, the transmission resource set information includes: time-domain transmission resource information and frequency-domain transmission resource information of the transmission resource set;

[0167] D13, the time interval between the start times of two adjacent transmission resource units in the transmission resource set;

[0168] In some embodiments, the indication of the time interval includes, but is not limited to, at least one of the following: P seconds, Q symbols, R time slots, S micro time slots, U OFDM symbols, and L times the message-transmission resource time length.

[0169] D14, Time Domain Length Information;

[0170] In some embodiments, the time-domain length information includes at least one of the following:

[0171] D141, Message Three-Code Information;

[0172] For example, the encoding information may include, but is not limited to, at least one of the following: whether line code is used, line code encoding method, whether channel coding is used, channel coding method, code rate, and number of repeated transmissions.

[0173] D142, the transmission resource duration of message three.

[0174] In some implementations, the transmission resource duration can be seconds, symbols, OFDM symbols, time slots, mini-time slots, etc.

[0175] D15, the termination time of the transmission resource set;

[0176] D16. The number of transmission resources included in the transmission resource set;

[0177] D17. The offset of the termination time of the transmission resource set relative to the start time of the transmission resource set.

[0178] In some embodiments, the frequency domain transmission resource information includes at least one of the following:

[0179] D21. Frequency domain information of each transmission resource in the transmission resource set;

[0180] In some embodiments, the frequency domain information of each transmission resource includes at least one of the following:

[0181] D211, the sending frequency of message three;

[0182] D212, the sub-channel index corresponding to the transmission frequency of message three;

[0183] D213, the frequency shift value of message three relative to message one;

[0184] D214, Frequency shift value of message three relative to the carrier;

[0185] D215, Square wave frequency used for square wave modulation to realize message three-frequency shift;

[0186] D216, The number of times the repeated encoding is used to implement message three-frequency shifting;

[0187] D217, a frequency factor used to implement message three-frequency shifting.

[0188] D22. The index of the frequency or frequency subset used for the transmission of message three in the transmission frequency set of message one.

[0189] In some embodiments, the index information may be explicit or implicit.

[0190] When explicitly instructed, obtain the target information via message two, including:

[0191] Retrieve the target indication information from message two;

[0192] Based on the target indication information, obtain the index information;

[0193] The target indication information includes at least one of the following:

[0194] D31, codepoint indication information, which is used to indicate the index information of the transmission resources of message three;

[0195] For example, it can indicate at least one of the time-domain index, frequency index, and time-frequency domain combined index;

[0196] It should be noted that the transmission resources in the message three transmission resource set can be numbered by frequency domain, time domain, or a combination of frequency and time domain. Therefore, when indicating code points, at least one of the time domain index, frequency index, or time-frequency domain combined index can be indicated.

[0197] D32. Bitmap indication information, where each bit in the bitmap indication information corresponds to one transmission resource used to carry message three (e.g., determining the correspondence between the bit number and the transmission resource index). This can be understood as the value of each bit in the bitmap indicating whether the corresponding transmission resource is used to schedule the transmission of message three. Each bit indicates a specific index information for the transmission resource; that is, the index information can be determined by the value of each bit in the bitmap.

[0198] For example, a bit set to 0 indicates that the corresponding transmission resource was not scheduled by message two to transmit message three, while a bit set to 1 indicates that the corresponding transmission resource was scheduled by message two to transmit message three. In other words, an A-IoT device can determine the target information based on this bitmap indication information. For instance, if the message three transmission resource set contains two transmission resources for carrying message three, and the bitmap indication information includes two bits, the first bit is associated with the first transmission resource (index #1), and the second bit is associated with the second transmission resource (index #2). For example, for A-IoT device #1, if the bitmap indication information includes two bits with values ​​of 0 and 1, it can be understood that the bitmap indication information instructs A-IoT device #1 to use the second transmission resource to transmit message three, meaning the index determined by the bitmap indication information is #2.

[0199] In some embodiments, when implicitly indicated, obtaining target information via message two includes:

[0200] The index information is determined based on the correlation between the index information and the target parameters.

[0201] The target parameter includes at least one of the following:

[0202] D41. The order in which the transmission resources of message two appear in the message two listening window;

[0203] D42. The order in which the A-IoT device identifier appears among all the A-IoT device identifiers contained in message 2.

[0204] In some embodiments, the association is predefined by the protocol or preconfigured by the reader.

[0205] In some embodiments, the association includes at least one of the following:

[0206] D51. The order in which the index information and the transmission resources of message two appear in the message two listening window directly correspond;

[0207] For example, the transmission resource of message 2 at the Zth index in the message 2 listening window corresponds to the transmission resource of message 3 at the Zth index in the message 3 transmission resource set.

[0208] D52. The index information directly corresponds to the order in which the A-IoT device identifier appears among all the A-IoT device identifiers contained in message two;

[0209] For example, the Xth A-IoT device identifier contained in message 2 corresponds to the transmission resource of message 3 at the Xth index in the transmission resource set of message 3.

[0210] D53. The index information and the order of appearance of the transmission resources of message two in the message two listening window correspond to the quotient and / or remainder.

[0211] For example, the quotient of the transmission resource of the Zth message in the message two listening window and P (i.e., Z / P) corresponds to the transmission resource of the Zth index of message three in the message three transmission resource set, where P is a constant.

[0212] D54. The index information corresponds to the quotient and / or remainder of the order of appearance of the A-IoT device identifier among all A-IoT device identifiers contained in message 2;

[0213] For example, the quotient (i.e., X / K) of the Xth A-IoT device identifier contained in message 2 corresponds to the transmission resource of message 3 at the Xth index in the transmission resource set of message 3.

[0214] It should be noted that the above examples consider time-domain resources and frequency-domain resources as a whole. In some embodiments, time-domain resources and frequency-domain resources can also be viewed independently. For example, for time-domain resources, the index information is used to correspond to the quotient of the appearance order of the time-domain resources of message two in the message two listening window. For example, for frequency-domain resources, the index information is used to correspond to the remainder of the appearance order of the frequency-domain resources of message two in the message two listening window. Of course, the above implementation is merely an example and does not constitute a limitation on the specific implementation of the embodiments of this disclosure.

[0215] Of course, the relationships in the embodiments of this disclosure are merely examples and do not constitute a limitation on the embodiments of this disclosure.

[0216] The specific implementation examples of the embodiments of this disclosure are illustrated below.

[0217] Application Scenario 1, corresponding to the above implementation scenario 1

[0218] In this application scenario, the reader indicates the transmission resources for message three by pre-configuring and / or indicating target information in the message that triggers random access.

[0219] The target information includes the time-domain offset of the start time of message three transmission resources relative to a first target time. This first target time includes at least one of the following: the end time of the message two listening window; the end time of message two containing the A-IoT device identifier; the end time of the message triggering random access; and the end time of the A-IoT device sending message one. The unit of the time-domain offset can be a symbol, OFDM symbol, time slot, micro-time slot, second, etc. For example, the message triggering random access indicates that the time-domain offset of the start time of message three transmission resources relative to the end time of message two is 2 symbols. As shown in Figure 2, Msg1#1 and Msg1#2 are D2R signals carrying Msg1 sent by A-IoT device 1 and device 2, respectively. After receiving Msg2#1 carrying its identifier, A-IoT device 1 starts sending message three 2 symbols after the end time of Msg2. A-IoT device 2 does the same.

[0220] Specifically, the target information includes time-domain length information of the transmission resources of message three, which includes at least one of the following:

[0221] The message contains three types of encoding information, such as whether line coding is used, the line coding method, whether channel coding is used, the channel coding method, the code rate, and the number of repeated transmissions.

[0222] The transmission resource duration of message three can be in the form of seconds, symbols, OFDM symbols, time slots, mini-time slots, etc.

[0223] Specifically, the target information includes frequency domain information of the transmission resources of message three, and the frequency domain information includes at least one of the following:

[0224] The sending frequency of message three, such as the sending frequency of message indication message three that triggers random access, is 900MHz;

[0225] The sub-channel index corresponding to the transmission frequency of message three, for example, the reader is pre-configured with a total of 8 sub-channels, with sub-channel indices from 0 to 8, and the message that triggers random access indicates the sub-channel with sub-channel index 3;

[0226] The frequency shift value of message 3 relative to Msg1. For example, if the transmission frequency of Msg1 is 900MHz, and the pre-configured frequency shift value of message 3 relative to Msg1 is 0.1MHz, then the transmission frequency of message 3 is 900.1MHz.

[0227] The frequency shift value of message three relative to the carrier is as follows: if the carrier frequency is 900MHz, and the pre-configured shift value of the transmission frequency of message three relative to the carrier frequency is 0.1MHz, then the transmission frequency of message three is 900.1MHz.

[0228] The square wave frequency used for frequency shifting of message three, such as a carrier frequency of 900MHz, and the square wave frequency used for frequency shifting of message three in the message indication triggering random access, is R times the information bit transmission rate. Therefore, the transmission frequency of message three is 9*10^6 times the information bit transmission rate. 8 +R / T b (Hz);

[0229] The number of repetitions used to implement the frequency shift of message three, for example, if the carrier frequency is 900MHz and the message indication triggering random access uses K repetitions to implement the frequency shift of message three, then the transmission frequency of message three is 9*10^6. 8 +K / T b (Hz);

[0230] Frequency factor used to implement message three-frequency shifting.

[0231] It should be noted that in this application scenario, the reader only needs to indicate the offset of the time-domain transmission resources of message three relative to the end time of message two, as well as the frequency-domain transmission resources of message three, so that the A-IoT device can determine its transmission resources for message three, resulting in low indication overhead.

[0232] Application Scenario 2, corresponding to the above implementation scenario 2

[0233] In this application scenario, the reader indicates the transmission resources for message three by pre-configuring and / or indicating target information in message two. Message two contains the following information:

[0234] A-IoT device identifiers, such as a random identifier generated by the device or a portion of its bits;

[0235] The frequency domain information of the transmission resources in message three can be found in application scenario one, and will not be repeated here.

[0236] The time-domain information of the transmission resources in message three includes at least one of the following:

[0237] The start time of message three transmission resources;

[0238] The time-domain length information of the transmission resources in message three can be found in application scenario one, and will not be repeated here.

[0239] The offset between the start time of the transmission resource of message three and the second target time, wherein the unit of the offset value can be a symbol, OFDM symbol, time slot, micro-time slot, second, etc.; the second target time includes at least one of the following:

[0240] The end time of the last message two listening window in the Y message two listening windows is shown as offset#1 in Figure 3; for example, the offset between the start time of message two indicating message three transmission resources and the end time of the last message two listening window in the two message two listening windows is 20 microseconds.

[0241] The end time of the message listening window of the A-IoT device is shown as offset#2 in Figure 3; for example, the offset between the start time of the pre-configured message three transmission resource and the end time of the message listening window is 1 micro-slot.

[0242] The end time of message two containing the A-IoT device identifier is shown as offset#3 in Figure 3; for example, the offset between the start time of the pre-configured message three transmission resource and the end time of message two containing the device identifier is 1 OFDM symbol;

[0243] The end time of the last transmission resource of message one in the X transmission resources is shown as offset#4 in Figure 3; for example, the offset between the start time of the transmission resource of message two indicating message three and the end time of the last transmission resource in the two transmission resources of message one is 2 time slots.

[0244] The end time of the A-IoT device sending message one is shown as offset#5 in Figure 3; for example, the offset between the start time of message three transmission resources and the end time of the A-IoT device sending message one is 64 code symbols.

[0245] The end time of the message that triggered random access.

[0246] It should be noted that in this application scenario, the reader can flexibly indicate the time and frequency resources for the transmission of message three to each A-IoT device through message two.

[0247] Application Scenario 3: Explicit Instructions Corresponding to Implementation Scenario 3

[0248] In this application scenario, the reader indicates the transmission resources in message three by pre-configuring and / or indicating the set of transmission resources in the message that triggers random access, and indicating index information in message two.

[0249] The transmission resource set information includes time-domain transmission resource information and / or frequency-domain transmission resource information of the transmission resource set.

[0250] Specifically, the time-domain transmission resource information includes at least one of the following:

[0251] The start time of the transmission resource set, or the offset between the start time of the transmission resource set and the third target time, wherein the third target time includes at least one of the following: the end time of the message two listening window of the A-IoT device, the end time of the last message two listening window among the M message two listening windows, the end time of message two containing the identifier of the A-IoT device, the end time of the message that triggers random access, the end time of the transmission resource of the last message one among the N message one transmission resources, and the end time of the A-IoT device sending message one.

[0252] The time interval between the start times of two adjacent transmission resource units in the transmission resource set, wherein the indication method of the time interval includes at least one of the following: P seconds, Q symbols, R time slots, S micro time slots, U OFDM symbols, and L times the length of Msg1 transmission resource unit;

[0253] The time-domain length information of the transmitted resources can be found in Application Scenario 1, and will not be repeated here.

[0254] The termination time of the transmission resource set, or the number of transmission resources for message three contained in the transmission resource set, or the offset of the termination time of the transmission resource set relative to its start time.

[0255] For example, the time offset between the start time of the message indicating the random access and the end time of the message two listening window is 64 symbols, the time interval between the start times of two adjacent transmission resource units in the transmission resource set is 128 symbols, and the transmission resource set contains two message three transmission resources. The message three transmission resource set is shown in Figure 4.

[0256] Specifically, frequency domain transmission resource information includes at least one of the following:

[0257] The frequency domain information of the transmission resources for each message 3 in the transmission resource set is detailed in Application Scenario 1 and will not be repeated here.

[0258] The transmission frequency set of Msg1 is an index of the frequency used for message three transmission, or an index of a subset of frequencies. For example, the transmission frequency set of Msg1 is {899.90MHz, 899.95MHz, 900.05MHz, 900.10MHz}, with indices 0, 1, 2, and 3 for each frequency. The message that triggers random access indicates that the frequency corresponding to frequency index 0, i.e., 899.90MHz, will be used as the frequency of the message three transmission resource set. As another example, if the subset corresponding to subset index 0 is {899.95MHz, 900.05MHz}, the frequency set corresponding to subset index 0 will be pre-configured as the frequency of the message three transmission resource set.

[0259] It should be noted that, in this application scenario, message two explicitly indicates index information. Explicit indication specifically includes at least one of the following indication methods (i.e., message two includes at least one of the following):

[0260] Codepoint information: Index information used to indicate the transmission resources of message three; for example, the transmission resource set contains 8 transmission resources for message three, with corresponding indices from 0 to 7. Message two instructs A-IoT device #1 to send message three on the transmission resource with index 7.

[0261] Bitmap indication information: Each bit in the bitmap corresponds to a transmission resource for message 3. It can be understood that each bit in the bitmap is used to indicate whether the transmission resource corresponding to that bit is used to transmit message 3. The transmission resource indicated by each bit corresponds to specific index information. In other words, the index information can be determined by the value of each bit in the bitmap.

[0262] It should be noted that in this application scenario, the reader can flexibly schedule the transmission resources of message three through message two, and reduce the indication overhead by indicating the repeated part of the time-frequency resource information once in the message that triggers random access.

[0263] Application Scenario 4: Implicit Instructions Corresponding to Implementation Scenario 3

[0264] In this application scenario, the reader indicates the transmission resources for message three by pre-configuring the transmission resource set information in the message that triggers random access and / or indicating index information in message two.

[0265] The transmission resource set information includes time-domain transmission resource information of the transmission resource set, and / or frequency-domain transmission resource information of the transmission resource set.

[0266] Specifically, the time-domain transmission resource information and frequency-domain transmission resource information can be found in the description of application scenario three, and will not be repeated here.

[0267] In this application scenario, message two implicitly indicates index information.

[0268] That is, the index information is determined based on the correlation between the index information and the target parameters;

[0269] The target parameter includes at least one of the following:

[0270] The order in which the transmission resources for message two appear in the message two listening window;

[0271] The order in which the A-IoT device identifier appears among all the A-IoT device identifiers contained in message 2.

[0272] Specifically, the relationship includes at least one of the following:

[0273] Direct correspondence: This can be a direct correspondence between the index information and the order in which the transmission resources of message two appear in the message two listening window; or a direct correspondence between the index information and the order in which the A-IoT device identifier appears among all A-IoT device identifiers included in message two. For example, the Zth message two in the message two listening window corresponds to the Zth message three transmission resource in the message three transmission resource set, as shown in Figure 5. The first message two in the message two listening window corresponds to the message three transmission resource with index #1 in the message three transmission resource set, and so on.

[0274] The quotient and / or remainder correspondence can be calculated by taking the quotient and / or remainder of the index information and the order of appearance of the transmission resources of message two in the listening window of message two; or it can be calculated by taking the quotient and / or remainder of the index information and the order of appearance of the A-IoT device identifier among all A-IoT device identifiers contained in message two. For example, the Zth device identifier among all device identifiers contained in message two corresponds to the (Z-1)mod 2+1th time-domain and (Z-1)div 2+1th message three transmission resource in the transmission resource set, as shown in Figure 6. Message two contains 4 device identifiers. Device identifier 1 corresponds to the first message three transmission resource in the time domain and the first message three transmission resource in the frequency domain, i.e., message three transmission resource 1, and so on for other device identifiers.

[0275] In some embodiments, this association can also be other predefined correspondence rules in the protocol, such as predefined correspondences where the Z1th message 2 transmission resource in the message 2 listening window corresponds to the Q1th transmission resource in the frequency domain of the message 3 transmission resource set, and the Z2th message 2 transmission resource in the message 2 listening window corresponds to the Q2th transmission resource in the frequency domain of the message 3 transmission resource set. For example, assuming Z1 = 1, Z2 = 2, Q1 = 1, Q2 = 4, the correspondence between message 2 transmission resources and message 3 transmission resources is shown in Figure 7.

[0276] It should be noted that the configuration method for this association is either protocol predefined or reader preconfigured (for example, the reader is preconfigured via R2D signals).

[0277] It should be noted that in this application scenario, by establishing a connection between message two and message three, an implicit indication of the transmission resources of message three is achieved, which further reduces the indication overhead compared to the method in application scenario three.

[0278] It should be noted that in the inventory scenario, the Msg3 transmission resources of each A-IoT device are different, and the corresponding SLIVs are also different. If all candidate SLIVs are pre-configured to A-IoT devices in the form of a table, the data volume of the table will be too large. A-IoT devices have limited data storage capacity, making it difficult to pre-store complex resource allocation tables; moreover, when the device's power is depleted, its pre-stored information may also be lost.

[0279] NR signal transmission is based on Orthogonal Frequency-Division Multiplexing (OFDM), therefore the bandwidth of NR signals is flexibly configurable. In contrast, D2R signals from A-IoT devices are based on single-tone or dual-tone sine wave transmission, and their bandwidth depends on the signal transmission rate. Therefore, the frequency resource indication method using Resource Indicator Value (RIV) is not suitable for A-IoT systems.

[0280] RFID access mechanisms only support Time Division Multiple Access (TDMA) for tags and cannot support Frequency Division Multiple Access (FDMA). This also presents the following problems: a) low resource utilization efficiency and long device access time; b) lack of frequency domain resource indication mechanism; c) tags that have sent RN16 immediately send EPC after receiving ACK signaling, so the reader does not need to specifically indicate D2R time domain transmission resources. Considering the high connection density of A-IoT devices and the fact that the A-IoT process may support both TDMA and FDMA multiple access methods simultaneously, the resource allocation methods in related RFID technologies are not suitable for A-IoT systems.

[0281] At least one embodiment of this disclosure provides a method for indicating transmission resources of A-IoT Msg3. Compared with the related mechanisms in NR and RFID, it can support both TDMA and FDMA multiple access modes of Msg3, and does not require A-IoT devices to store a large amount of data. This method is compatible with the working mechanism of A-IoT systems and the capabilities of A-IoT devices themselves.
