Description

Resource determination methods, apparatus, equipment, and storage media

[0001] This disclosure claims priority to Chinese Patent No. 202411015812.3, filed with the Chinese Patent Office on July 26, 2024, entitled “Resource Determination Method, Apparatus, Equipment, Storage Medium”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a resource determination method, apparatus, device, and storage medium. Background Technology

[0003] Currently, the standard defines an Ambient IoT (AIoT) device, where IoT stands for Internet of Things. AIoT devices have little or no power supply, characterized by low energy consumption and low cost. The standard defines three types of AIoT devices: Type A: no energy storage capacity, no independent signal generation capability, transmits signals via backscattering; Type B: has energy storage capacity, no independent signal generation capability, transmits signals via backscattering, and the stored energy can be used to amplify the power of the backscattered signal; Type C: has energy storage capacity, has independent signal generation capability, and can use radio frequency (RF) devices for signal transmission. The general principle for backscattering is as follows: the reader / writer generates the RF excitation signal, the reflective tag consists of devices that can reflect RF signals, the reader / writer sends the RF signal to the reflective tag, the reflective tag receives the signal from the excitation source, and then reflects the RF signal.

[0004] In AIoT systems, during communication between AIoT devices and reader / writer devices, the AIoT device first determines the resources used for signal transmission. Based on these resources, it sends a D2R signal (i.e., the signal sent from the AIoT device to the reader / writer device) to the reader / writer device. However, the resource determination methods used by AIoT devices in related technologies are not adaptable to different scenarios, which can easily lead to poor signal transmission flexibility for AIoT devices.

[0132] To make the technical problems, solutions, and advantages of this disclosure clearer, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0133] This disclosure provides a resource determination method, apparatus, device, storage medium, and computer program product to address the problem of poor codebook availability.

[0134] The technical solutions provided in this disclosure are applicable to a variety of systems, especially 6th Generation (6G) mobile communication 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), 5th Generation (5G) New Radio (NR), and 6G systems. All of these systems include terminal equipment and network equipment. The system may also include a core network component, such as the Evolved Packet System (EPS) or the 5G system (5GS).

[0135] Please refer to Figure 1, which is a schematic diagram of the network architecture applicable to the present disclosure. As shown in Figure 1, it includes a terminal 11 and a network device 12.

[0136] The terminal involved in this disclosure 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 may be called User Equipment (UE). The wireless terminal device can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) or 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 radio access network. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), Redcap terminals, and Low Power Wide Area (LPWA) terminals. Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile terminal, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device; however, this disclosure does not limit the terminology used in this embodiment.

[0137] 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 base station in 6G, 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.

[0138] Network devices and terminals 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. It can also be diversity transmission, pre-coded transmission, or beamforming transmission, etc.

[0139] Please refer to Figure 2, which is a flowchart of a resource determination method provided in an embodiment of this disclosure, applied to an AIoT device. As shown in Figure 2, it includes the following steps:

[0140] Step 201: Receive the first signal sent by the read / write device;

[0141] Step 202: Based on the first signal, obtain the target resource information for sending the second signal from at least one transmission resource information.

[0142] The first signal may include a Reader-to-Device (R2D) signal, comprising at least one of an R2D preamble, R2D control information, and R2D data information. The second signal may be a Device-to-Reader (D2R) signal, comprising at least one of a D2R preamble, D2R control information, and D2R data information. The read / write device may send the first signal to the AIoT device, thereby enabling the AIoT device to determine target resource information from at least one transmission resource information based on the first signal sent by the read / write device, and then send the second signal. Exemplarily, the read / write device may be, but is not limited to, a reader / writer.

[0143] It should also be noted that the second signal can be one or more, meaning there can be at least one second signal. If there are multiple second signals, they can be multiple second signals sent by a single AIoT device, or different second signals sent by different AIoT devices. Based on the first signal, target resource information for sending each of the at least one second signal can be obtained, i.e., the target resource information corresponding to each second signal. Thus, for each second signal, subsequent transmission can be performed based on its corresponding target resource information. For example, the reader can be set in at least one of the following network elements: a base station; an intermediate node (a node located between the base station and the AIoT device), etc.

[0144] In one example, after step 202, the method may further include: sending a second signal to the reader / writer device based on the target resource information. That is, the target resource information is determined based on the first signal sent by the reader / writer device, and a second signal is sent to the reader / writer device to improve the transmission performance of the second signal. Furthermore, the second signal may include at least one of D2R preamble, D2R control information, and D2R data information. The second signal may carry the target resource information to facilitate the reader / writer device's reception of the second signal based on the target resource information sent by the AIoT device.

[0145] In this embodiment, the read / write device can send a first signal to the AIoT device to instruct the AIoT device on target resource information for sending a second signal. After receiving the first signal, the AIoT device can obtain the target resource information from at least one transmission resource information based on the first signal, and then send the second signal. That is, in this embodiment, the AIoT device can obtain the target resource information from at least one transmission resource information based on the first signal sent by the read / write device, and then send the second signal. This adapts to different application scenarios and improves the signal transmission flexibility of the AIoT device.

[0146] In some embodiments, the first signal carries target information, which is used to obtain target resource information.

[0147] In other words, the first signal can carry target information for obtaining target resource information of the second signal. The target information is carried in the first signal, and the target resource information can be obtained through the target information. In this way, after the AIoT device receives the first signal, it can obtain the target resource information from at least one transmission resource information based on the target information carried in the first signal, and use it to send the second signal, thereby improving the signal transmission performance of the AIoT device.

[0148] In some embodiments, the target information includes at least one of the following:

[0149] The first piece of information about the target resource;

[0150] The second piece of information about the target resource information is information that is related to the target resource information.

[0151] It should be noted that, as can be understood, the first information can be used to indicate target resource information through a first method, and the second information can be used to indicate target resource information through a second method. That is, the first information and the second information can indicate target resource information in different ways. For example, target information can explicitly indicate target resource information, and target information may include the first information, which can be used to explicitly indicate target resource information. Target information can also implicitly indicate target resource information, and target information may include the second information, which can be used to implicitly indicate target resource information. The second information can have an association relationship (or correspondence relationship) with the target resource information. In this way, the target resource information can be obtained based on the second information.

[0152] In some embodiments, the first information includes at least one of the following:

[0153] The first instruction information is used to indicate the specific value of the target resource information;

[0154] Index value, the index value is the index value associated with the target resource information.

[0155] In this embodiment, the target resource information can be explicitly indicated through the first indication information and / or index value. It is understood that the protocol predefines and pre-configures resource information for at least one second signal. Different second signals have corresponding index values. The first signal can carry the index value associated with the target resource information, so that the AIoT device can obtain the target resource information corresponding to the index value after receiving the first signal. The first information may also include first indication information for indicating the specific value of the target resource information. This allows the AIoT device to directly obtain the specific value of the target resource information based on the first indication information. For example, if the target resource information includes the length of a time-domain resource unit, the first indication information can directly indicate the specific value of the time-domain resource unit length.

[0156] In some embodiments, the second information includes at least one of the following:

[0157] The second indication information is used to indicate the target information type of the second signal, and the target information type has a corresponding relationship with the target resource information.

[0158] The third indication information is used to indicate the target clock information of the second signal. The target clock information is related to the target resource information.

[0159] The first field has a corresponding relationship between the pattern in the first field and the target resource information;

[0160] The target duration of the second signal is related to the target resource information.

[0161] The second signal contains target payload information, and there is a correspondence between the target payload information and the target resource information.

[0162] The fourth indication information is used to indicate the correlation between the target resource information of the second signal and the resource information of the first signal;

[0163] The first resource information of the second signal;

[0164] The fifth indication information is used to indicate the association between the target resource information of the second signal and the first resource information of the second signal.

[0165] For example, the second information may include second indication information, which indicates the target information type of the second signal. There is a correspondence between the target information type of the second signal and the target resource information. Thus, the target resource information can be determined based on the target information type and this correspondence. As another example, the second information may include third indication information, which can be used to indicate the target clock information of the second signal. There is an association between the target clock information of the second signal and the target resource information. Thus, the target resource information can be determined based on the target clock information and this association. As yet another example, the second information may include a first field, the pattern of which corresponds to the target resource information. It should be noted that the first field may be at least one of the following: some or all fields in the preamble of the first signal, some or all fields in the control information of the first signal, or some or all fields in the data information of the first signal. Thus, the target resource information can be determined based on the pattern of the first field in the second information and this correspondence. As yet another example, the second information may include the target duration of the second signal, and there is a correspondence between the target duration of the second signal and the target resource information. Thus, the target resource information can be determined based on the target duration and this correspondence. For example, the second information may include target payload information of the second signal, and there is a correspondence between the target payload information and target resource information of the second signal. Thus, the target resource information can be determined based on the target payload information and this correspondence. For example, the second information may include fourth indication information, which indicates the association between the target resource information of the second signal and the resource information of the first signal. Thus, the target resource information (e.g., the time-domain resource unit length of the first signal) can be determined based on the resource information of the first signal (e.g., the time-domain resource unit length of the first signal) and this association. For example, the second information may include first resource information of the second signal. Thus, the target resource information can be determined based on the first resource information of the second signal and the association between the target resource information of the second signal and the first resource information of the second signal (e.g., through protocol predefinition and / or read / write device preconfiguration). For yet another example, the second information may include fifth indication information, which indicates the association between the target resource information of the second signal and the first resource information of the second signal. That is, this association can be carried by the first signal. Thus, the target resource information can be determined based on the resource information of the first signal and the association indicated by the fifth indication information.

[0166] In this embodiment, the second information may include at least one of the following: second indication information, third indication information, first field, target payload information, fourth indication information, first resource information of the second signal, and fifth indication information. That is, it may include any one of the following: second indication information, third indication information, first field, target payload information, fourth indication information, first resource information of the second signal, and fifth indication information. It may also be any combination of the following: second indication information, third indication information, first field, target payload information, fourth indication information, first resource information of the second signal, and fifth indication information.

[0167] For example, taking the target resource information including the length of a time-domain resource unit, where the time-domain resource unit is the first time unit, as an example, this embodiment can obtain the relevant information for determining the first time unit in the following way, and subsequently determine the length of the first time unit using the relevant information of the first time unit:

[0168] Method 1: The AIoT device receives a first signal and determines the length of the first time unit of the second signal based on the first time unit indication information of the second signal carried in the first signal. The indication information for the length of the first time unit of the second signal may include at least one of the following:

[0169] A specific indication of the length of the first time unit of the second signal, or a related index value;

[0170] The target information type of the second signal, different second signal information types correspond to different chip durations. The target resource information corresponding to the target information type can be determined based on the correspondence between at least one information type and at least one transmission resource information of the second signal, thereby determining the length of the first time unit.

[0171] The clock length / sampling frequency of the second signal, and the correlation between the clock of the second signal and the length of the first time unit, are used to determine the length of the first time unit.

[0172] Method Two: The AIoT device receives a first signal, which may carry second related information about a second signal. This second related information may include at least one of the following: the signal's duration (corresponding to the target duration), payload information (corresponding to the target payload information), or information type (corresponding to the target information type). Based on this second related information, the AIoT device determines the length of a first time unit of the second signal. The correspondence between the length of the first time unit and the second related information of the second signal may be predefined or preconfigured according to the protocol.

[0173] Method 3: The first signal (e.g., the preamble) carries relevant information about the first time unit of the second signal, such as the correlation between the length of the first time unit of the second signal and the length of the time-domain resource unit of the first signal. For example, the length of the first time unit of the second signal is equal to or has a certain correlation with the length of the time-domain resource unit of the first signal, such as the length of the first time unit being M times or 1 / M of the length of the time-domain resource unit of the first signal.

[0174] Method 4: The first signal (e.g., a preamble) carries the common time-domain resource unit (TROM) length of the second signal. This TROM length can be the default TROM length or the basic TROM length. It should be noted that the TROM length can also be the clock length of the second signal. The TROM of the second signal is a part of the first time unit of the second signal.

[0175] Method 5: The first signal preamble and the first signaling (e.g., control information) jointly carry the length of the first time unit of the second signal. The preamble carries the length of the common time domain resource unit, the basic time domain resource unit, or the minimum time domain resource unit. The first signaling carries relevant information about the length of the first time unit of the second signal and the length of the common time domain resource unit, such as fifth indication information used to indicate the correlation between the length of the first time unit of the second signal and the length of the common time domain resource unit of the first signal.

[0176] Method 6: The data information of the first signal carries relevant information about the first time unit of the second signal. For example, the length of the first time unit of the associated second signal is selected based on the information of the first signal carried in the data information of the first signal.

[0177] In this embodiment, the second information may include at least one of the following: second indication information, third indication information, first field, target payload information, fourth indication information, first resource information of the second signal, and fifth indication information, to obtain target resource information. For different information in the second information, the obtained target resource information may be the same or different. The target resource information can be obtained through this at least one piece of information, which can improve the flexibility of obtaining target resource information.

[0178] In some embodiments, the first resource information may include, but is not limited to, at least one of the following: common time-domain resource unit length; basic time-domain resource unit length; and minimum time-domain resource unit length. Wherein, the common time-domain resource unit length refers to the time-domain resource unit length supported by the resource information lengths of at least one second signal; the basic time-domain resource unit length refers to the resource information length of at least one second signal being an integer multiple or fraction of the basic time-domain resource unit length; and the minimum time-domain resource unit length refers to the smallest length unit among the resource information lengths of at least one second signal.

[0179] In some embodiments, the correspondence between target information type and target resource information, the association between target clock information and target resource information, the correspondence between the pattern of the first field and target resource information, the correspondence between target duration and target resource information, and the correspondence between target payload information and target resource information are determined by at least one of the following methods: protocol predefinition, preconfiguration by the read / write device, and carrying the first signal.

[0180] The above relationships can be predefined by the protocol, preconfigured, or carried by the first signal (i.e., the above relationships are carried in the first signal) to improve the flexibility of the above relationship configuration.

[0181] In some embodiments, the first signal may include at least one of the following:

[0182] Preamble;

[0183] Control information;

[0184] Data information.

[0185] The target resource information of the second signal is obtained by using a first signal. The first signal may include at least one of a preamble, control information, and data information. It is understood that the target information can be carried by at least one of the preamble, control information, and data information to obtain the target resource information of the second signal. For example, the time-domain resource information of the second signal may be specifically indicated in the control information. For instance, the control information may carry a specific numerical indication of the time-domain resource length of the second signal, or it may carry an index value of the time-domain resource length of the second signal. The time-domain resource information of the second signal can be associated with the preamble. The time-domain resource information of the second signal can be determined through the preamble. For example, the preamble can also carry the first resource information of the second signal. In this way, the length of the time-domain resource unit of the second signal can be determined based on the first resource information of the second signal. Alternatively, the preamble can carry the association between the time-domain resource information of the second signal and the first resource information of the second signal. In this way, the length of the time-domain resource unit of the second signal can be determined based on the first resource information of the second signal and the association. Or, the target resource information can be indicated by a combination of the preamble and control information. For example, the preamble carries the first resource information of the second signal, and the control information carries the association between the time-domain resource information of the second signal and the first resource information of the second signal. In this way, the target resource information can be determined based on the first resource information of the second signal and the association. In addition, the time-domain resource information of the second signal can be related to the data information. The time-domain resource information of the second signal can be determined through the data information. For example, the information type can be determined based on the data information sent by the reading and writing device. Based on the determined information type and the correspondence between at least one information type and at least one resource information of the second signal, the target information resource corresponding to the information type can be determined.

[0186] That is, target information can be transmitted to AIoT devices by carrying at least one of preamble (R2D preamble), control information (R2D control novel), and data information (R2D data information), which can improve the flexibility of information transmission.

[0187] In some embodiments, the target resource information includes information about time-domain resource units, wherein the time-domain resource unit includes at least one of the following:

[0188] Transmission resource unit for generating and / or transmitting the second signal;

[0189] The second signal is generated and / or transmitted clock information;

[0190] A counting unit for the second signal generation and / or transmission time.

[0191] In other words, the time-domain resource unit may include, but is not limited to, at least one of the aforementioned transmission resource unit, clock information, and counting unit for the second signal. The transmission resource unit can be understood as the basic unit used for the transmission of the second signal; the clock for generating and / or transmitting the second signal may be the smallest time unit maintaining the overall timing of the AIoT device, and this clock may be consistent with the sampling frequency of the second signal or with the time unit of signal transmission; the counting unit may count, receive, and / or transmit signals based on the transmission resource unit and / or the AIoT device clock. The relationship between these three time-domain resource units can be simplified to the same frequency, or they may be different.

[0192] For example, the relationship between these three types of time-domain resource units can be one or more of the following:

[0193] Scenario 1: The AIoT device maintains an internal clock, which is the smallest time unit. The transmission resource unit and / or counting unit of the second signal are multiples of this clock. The specific multiple relationship can be predefined by the protocol or specifically carried / indicated by the first signal. For example: the frequency of the internal clock or sampling point of the device is N1 (MHz), and the frequency of the second signal transmission resource unit is M1 times that of the internal clock or sampling point frequency. If carried by the first signal, the length of the second signal transmission resource unit is 1 / (N1*M1) seconds.

[0194] Scenario 2: The clock of the AIoT device will be adjusted to the target clock frequency or sampling point frequency based on the specific information carried / indicated by the first signal. The transmission resource unit and / or counting unit of the second signal can be indicated solely by the first signal. For example: the default clock or sampling point frequency inside the device is N (MHz), and the first signal carries a target clock frequency or sampling point frequency that is M2 times or 1 / M2 of the default frequency, then the device will adjust the clock frequency or sampling point frequency to the target value N*M2 or N / M2;

[0195] Scenario 3: At least two of the following are identical: the transmission resource unit of the second signal, the clock for generating / transmitting the second signal, and the counting unit. For example, the transmission resource unit and the counting unit of the second signal have the same length, which can be a multiple of the device's clock. Alternatively, the transmission resource unit, the counting unit, and the clock of the AIoT device have the same length, etc.

[0196] In some embodiments, the information of the time-domain resource unit includes:

[0197] The length of the time-domain resource unit.

[0198] In some embodiments, the length of a transmission resource unit includes at least one of the following:

[0199] The length corresponding to the time slot, subframe, or frame length of the second signal;

[0200] The length of each bit in the information bits of the target signal, the target signal including a second signal and / or a signal obtained by performing at least one of the following processes on the second signal:

[0201] Add a Cyclic Redundancy Check (CRC) code;

[0202] coding;

[0203] modulation.

[0204] In this embodiment, the length of the transmission resource unit can be the length corresponding to the time slot, subframe, or frame of the second signal; it can also be the length of each bit in the information bits of the second signal; or it can be the length of each bit in the information bits of the signal obtained by adding CRC, encoding, and modulation to the second signal, or any combination thereof. For example, it can be the length of each bit in the information bits of the signal after adding CRC to the second signal, the length of each bit in the information bits of the signal after encoding the second signal, the length of each bit in the information bits of the signal after modulation of the second signal, the length of each bit in the information bits of the signal after adding CRC and encoding the second signal, the length of each bit in the information bits of the signal after adding CRC and modulation the second signal, or the length of each bit in the information bits of the signal after encoding and modulation the second signal, etc.

[0205] In some embodiments, the association between the target clock information and the target resource information of the second signal includes the target resource information being N times or 1 / N times the target clock information, where N is a positive number.

[0206] It should be noted that the target clock information in this embodiment can be a target clock frequency or a target clock length. For example, if the target clock length is X, and the correlation is that the target resource information is N times the target clock information, then the length of the clock for generating and / or transmitting the second signal in the target resource information is N*X. As another example, if the target clock frequency is Y, and the correlation is that the target resource information is N times the target clock information, then the clock frequency for generating and / or transmitting the second signal in the target resource information is N*Y, that is, the length of the clock for generating and / or transmitting the second signal in the target resource information is 1 / (N*Y).

[0207] In some embodiments, the association indicated by the fourth indication information includes: the target resource information of the second signal is M times or 1 / M times the resource information of the first signal, where M is a positive number.

[0208] In some embodiments, the association indicated by the fifth indication information includes: the target resource information of the second signal is L times or 1 / L times the first resource information, where L is a positive number.

[0209] In some embodiments, obtaining target resource information for transmitting the second signal from at least one transmission resource information based on the first signal includes at least one of the following:

[0210] Obtain the target resource information indicated by the first indication information;

[0211] Obtain the target resource information corresponding to the index value;

[0212] Based on the target information type and the first correspondence, the target resource information corresponding to the target information type is determined. The first correspondence includes a correspondence between at least one information type and at least one resource information of the second signal. The target information type is determined by at least one of the following methods: indication by the first signal; protocol predefinition; preconfiguration of the read / write device.

[0213] Based on the target clock information and the first association relationship, the target resource information corresponding to the target clock information is determined, wherein the first association relationship includes the association relationship between the target clock information and the resource information of the second signal, and the target clock information is determined by at least one of the following methods: the first signal indication; protocol predefinition; the read / write device preconfiguration;

[0214] Based on the pattern of the first field and the second correspondence, the target resource information corresponding to the pattern of the first field is determined, wherein the second correspondence includes a correspondence between at least one pattern and at least one resource information of the second signal;

[0215] Based on the target duration and the third correspondence, the target resource information corresponding to the target duration is determined, wherein the third correspondence includes a correspondence between at least one duration and at least one resource information of the second signal, and the target duration is determined by at least one of the following methods: indication by the first signal; protocol predefinition; preconfiguration of the read / write device;

[0216] Based on the target payload information and the fourth correspondence, the target resource information corresponding to the target payload information is determined, wherein the fourth correspondence includes a correspondence between at least one payload information and at least one resource information of the second signal, and the target payload information is determined by at least one of the following methods: indication by the first signal; protocol predefinition; preconfiguration of the read / write device;

[0217] Based on the resource information of the first signal, and the association between the target resource information of the second signal indicated by the fourth indication information in the first signal and the resource information of the first signal, the target resource information corresponding to the resource information of the first signal is determined.

[0218] Based on the first resource information of the second signal, the target resource information corresponding to the first resource information is determined;

[0219] Based on the first resource information and the association between the target resource information of the second signal indicated by the fifth indication information in the first signal and the first resource information, the target resource information corresponding to the first resource information is determined;

[0220] Based on the data information of the first signal and the first correspondence, the target resource information corresponding to the data information is determined.

[0221] It should be noted that, in this embodiment, the first signal indication can specifically be the second information indication in the first signal. For example, the first correspondence, first association, second correspondence, third correspondence, and fourth correspondence can be determined through at least one of the following methods: protocol predefinition, read / write device preconfiguration, and carrying via the first signal. Furthermore, the target information type used to determine the target resource information can be indicated by the first signal, predefined by the protocol, or preconfigured by the read / write device. The first correspondence can also be predefined by the protocol, preconfigured by the read / write device, or carried via the first signal. It should be noted that at least one of the target information type and the first correspondence must be carried or indicated by the first signal. For example, if the target information type is predefined and / or preconfigured, then the first correspondence is carried by the first signal. Similarly, if the first correspondence is predefined and / or preconfigured, then the target information type is indicated by the first signal. Furthermore, if the target information type is indicated by the first signal, the first correspondence can be carried by the first signal, predefined, or preconfigured. Finally, if the first correspondence is carried by the first signal, the target information type can be indicated by the first signal, predefined, or preconfigured. Additionally, it should be noted that if the second information includes the first resource information of the second signal, the process of determining the target resource information corresponding to the first resource information based on the first resource information of the second signal can be based on the first resource information of the second signal and a predefined or pre-configured association between the target resource information of the second signal and the first resource information. Furthermore, it should be noted that the target information can be carried by data information, such as carrying the target information type, to obtain the target resource information. Alternatively, the resource information corresponding to the data information can be determined based on the data information of the first signal and the first correspondence. In this process, the information type of the first signal can be determined first based on the data information of the first signal, and the corresponding target resource information can be determined according to the information type of the first signal and the first correspondence.

[0222] For example, taking the first signal as including at least one of R2D preamble, R2D control information (corresponding to R2D signaling), and R2D data information, and the target resource information as the length of the first time unit, the process of an AIoT device determining the length of the first time unit is illustrated. For instance, the AIoT device can determine the length of the first time unit based on at least one of the following: R2D preamble, R2D signaling, D2R payload, AIoT device capabilities (e.g., including but not limited to AIoT device computing power, storage capacity, etc.), and D2R information type. After determining the length of the first time unit, the AIoT device can carry the length of the first time unit in a second signal and send it to the reader / writer device. For example, the AIoT device can carry the length of the first time unit through the D2R preamble and / or through the D2R control information and send it to the reader / writer device, so that the reader / writer device can receive the second signal based on the length of the first time unit in the second signal sent by the AIoT device.

[0223] In this embodiment, at least one of the above-mentioned methods for obtaining target resource information can be selected. The target resource information obtained by different methods can be the same or different. That is, the target resource information of the second signal can be obtained by any of the above-mentioned methods. Each method can obtain one target resource information. Therefore, by obtaining the target resource information for sending the second signal through the above-mentioned methods, the flexibility of obtaining target resource information can be improved.

[0224] Please refer to Figure 3, which is a flowchart of a resource determination method provided in an embodiment of this disclosure, applied to a read / write device. As shown in Figure 3, it includes the following steps:

[0262] The process of the above method will be specifically described below with some specific embodiments.

[0263] Related technical introduction:

[0264] A new type of IoT device, namely AIoT device (also known as A-IoT device), has little or no power supply, characterized by low energy consumption and low cost. It can be categorized into three types: Type A, Type B, and Type C. Type A and Type B AIoT devices have little or no power supply, cannot actively communicate, and can only backscatter received signals, carrying information in the backscattered signal. Type C AIoT devices can actively transmit signals. Considering the low power consumption, low complexity, and limited or no power supply characteristics of AIoT devices, their transmission methods differ from related wireless air interface (NR) systems. For example, Type A: no energy storage capacity, no independent signal generation capability, transmits signals via backscattering; Type B: has energy storage capacity, no independent signal generation capability, transmits signals via backscattering, and the stored energy can be used to amplify the power of the backscattered signal; Type C: has energy storage capacity, has independent signal generation capability, and can use radio frequency devices for signal transmission.

[0265] A backscatter communication system consists of an excitation signal source and a signal reflection device, typically composed of a reader and a reflective tag. The reader generates the radio frequency (RF) excitation signal, while the reflective tag is a device capable of reflecting the RF signal. The reader sends an RF signal to the reflective tag, which receives the signal from the excitation signal source and reflects it back. By changing the load impedance of the reflective tag's antenna, information is modulated into the backscattered signal. For example, when the reflection coefficient is configured to the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured to the second reflection coefficient, the excitation signal is completely reflected; and when the reflection coefficient is configured to the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0266] Figure 4 shows a network topology for AIoT devices, in which AIoT devices communicate directly and bidirectionally with network devices (e.g., base stations (BS)). Communication between the base station and the AIoT device includes loop AIoT data and / or signaling. In this topology, the BS sending signals to the AIoT device may be different from the BS receiving signals from the AIoT device.

[0267] Figure 5 shows a network topology for AIoT devices. In this topology, the AIoT devices communicate bidirectionally with an intermediate node located between the AIoT devices and the base station. Communication between the AIoT devices and the base station is achieved through this intermediate node. In this topology, the intermediate node can be a relay node capable of transmitting AIoT signals, an integrated access and backhaul (IAB) node, a UE (User Equipment), a repeater, etc. The intermediate node transmits AIoT data and / or signaling between the BS (Base Station) and the AIoT devices.

[0268] The communication block diagram of the AIoT device is shown in Figure 6. The AIoT device can communicate with network nodes, which can be base stations, intermediate nodes, etc. In this embodiment, the reader can be set in the base station, intermediate node, etc. That is, Figure 6 can also represent the communication principle between the AIoT device and the reader.

[0269] The waveform of D2R signals differs from that of NR signals, making it impossible to transmit and / or receive D2R signals using the same transmission resource limitations as NR systems. For example, AIoT D2R signal reception cannot be performed using the NR frame structure. Since AIoT device transmission requires timing based on time-domain basic units, the timing of D2R transmission needs to be determined based on D2R time-domain resource units. The D2R time-domain resource units require consistent understanding between the reading / writing device and the AIoT device. The transmission resource information for D2R signals in an AIoT system may require at least one D2R transmission resource, which is associated with the D2R data type, device type, etc., raising the question of how to indicate these transmission resources.

[0270] This disclosure provides a resource determination method, which is illustrated by taking the resource as a time-domain resource and the target resource information as time-domain resource information, such as the information of a time-domain resource unit, with the first signal being an R2D signal and the second signal being a D2R signal.

[0271] The main idea of ​​the embodiments of this disclosure is that the reading and writing device indicates the time-domain resource information of at least one D2R signal of the AIoT device through R2D signals (for example, including but not limited to: at least one of R2D preamble, R2D control information, R2D data information, etc.).

[0272] For example, when supporting time-domain resource information for multiple D2R signals, the specific method for indicating the time-domain resource information of the D2R signals includes at least one of the following:

[0273] Scenario 1: Carried via R2D preamble and / or R2D control information;

[0274] Scenario 2: The time-domain resource information corresponding to the D2R signal sent to the reading and writing device is carried in the D2R preamble and / or D2R control information.

[0275] Scenario 3: Carried via R2D preamble and D2R control information (the time-domain resource information of the D2R signal can be carried in the D2R control information and sent to the reading and writing device);

[0276] Scenario 4: Data information carried via R2D.

[0278] The time-domain resource unit of a D2R signal includes at least one of the following: a transmission resource unit for the generation and / or transmission of a D2R signal, clock information for the generation and / or transmission of a D2R signal, a counting unit for the generation and / or transmission time of a D2R signal, etc.

[0279] Information about the time-domain resource units of a D2R signal may include the length of the time-domain resource unit of the D2R signal;

[0280] The time-domain resource units of the D2R signal and the R2D signal have a certain correlation, including at least one of the following:

[0281] Scenario 1: The time-domain resource information of D2R is specifically indicated by the R2D signal;

[0282] Case 2: The time-domain resource information of D2R is associated with the time-domain resource unit (also called R2D chip) of R2D, such as: having the same length, being N times or 1 / N times the length of R2D chip;

[0283] Case 3: The time-domain resource information of D2R is jointly indicated by the time-domain resource unit of R2D and the D2R signal.

[0284] The specific process of the scheme in this disclosure embodiment includes at least one of the following:

[0285] The protocol predefines and / or the read / write device preconfigures one or more D2R transmission resource information, wherein the D2R signal transmission resource information includes relevant information such as the length of the first time unit (time domain resource unit). The first time unit may include, but is not limited to, at least one of: a D2R signal transmission resource unit, clock information for the generation and / or transmission of the D2R signal, and a counting unit for the generation and / or transmission time of the D2R signal.

[0286] An AIoT device receives an R2D signal sent by a reader / writer. The R2D signal may include, but is not limited to, at least one of the following: an R2D preamble, R2D control information, or R2D data. The R2D signal carries time-domain resource-related information of the D2R signal (e.g., information related to time-domain resource units), including at least one of the following:

[0290] An AIoT device receives an R2D signal and, based on at least one of the R2D preamble, R2D control information, and R2D data, obtains relevant information for the first time unit, such as the length of the first time unit, including at least one of the following:

[0291] Method 1: The AIoT device receives the R2D signal and determines the length of the first time unit of D2R based on the D2R first time unit indication information carried in the R2D signal. Here, the indication information for the length of the first time unit of D2R is:

[0292] Option 1: A specific indication of the length of the first time cell in D2R, or the relevant index value.

[0293] Option 2: D2R information type. Different D2R information types correspond to different chip durations.

[0294] Option 3: D2R clock length / sampling frequency, the relationship between the D2R clock and the D2R chip length.

[0295] Method 2: The AIoT device receives an R2D signal, which carries second related information about D2R. This second related information includes at least one of the following: the D2R signal's connection time (corresponding to the target duration), payload information (corresponding to the target payload information), or information type (corresponding to the target information type). Based on this second related information, the AIoT device determines the length of the first time unit of D2R. The correspondence between the length of the first time unit of D2R and the second related information can be predefined or preconfigured according to the protocol.

[0296] Method 3: The R2D preamble carries information related to the first time unit of the D2R, such as the relationship between the length of the first time unit of the D2R and the length of the time-domain resource unit of the R2D. For example, the length of the first time unit of the D2R is equal to the length of the time-domain resource unit of the R2D, or they have a certain relationship, such as the length of the first time unit being M times or 1 / M of the length of the time-domain resource unit of the R2D. It should be noted that the common time-domain resource unit length of the D2R can be the same as the length of the time-domain resource unit of the R2D, or they can be independent information sequences.

[0297] Method 4: The R2D preamble carries the common time-domain resource unit (TLU) length of the D2R. This TLU length can be the default (preset) TLU length or the basic TLU length. It should be noted that the common time-domain resource unit length can also be the D2R clock length. The common time-domain resource unit of the D2R is part of the first time unit of the D2R. The common time-domain resource unit length of the D2R can be the same information sequence as the time-domain resource unit length of the R2D, or they can be independent information sequences.

[0298] Method 5: The R2D preamble and R2D signaling jointly carry the length of the first time unit of D2R. The R2D preamble carries the length of the common time domain resource unit, the basic time domain resource unit, or the minimum time domain resource unit. The R2D signaling carries relevant information about the length of the first time unit of D2R and the length of the common time domain resource unit, such as fifth indication information used to indicate the correlation between the length of the first time unit of D2R and the length of the common time domain resource unit of the R2D signal.

[0299] Method 6: The R2D data information carries relevant information about the first time unit of D2R. For example, select the associated first time unit of D2R based on the first R2D information carried in the R2D data information.

[0300] AIoT devices determine the length of the first D2R time unit based on R2D signals, one or more D2R first time unit information predefined by the protocol or pre-configured by the read / write device, the information type of the AIoT device, device capabilities, and other information. For example, it may specifically include at least one of the following:

[0301] Method 1: The AIoT device carries the information of the first time unit of D2R through the D2R preamble based on at least one of the following: R2D preamble, R2D control information, and R2D data.

[0302] Method 2: The AIoT device determines the target D2R first time unit information based on at least one D2R first time unit information predefined or preconfigured by the protocol and relevant information of the device itself, such as device capabilities, D2R information type, D2R information payload, etc., and carries the D2R first time unit information through D2R preamble and / or D2R control information.

[0303] Method 3: The AIoT device determines the length of the first D2R time unit based on information such as the R2D preamble, R2D control information, D2R information type carried by at least one of the R2D data, and D2R payload, and carries this information in the D2R preamble and / or D2R control information. The information type and payload are indicated by the R2D information.

[0304] AIoT devices send the first time unit length to the read / write device through at least one of the following: D2R preamble, D2R control information, etc.

[0305] Example 1: The relationship between the transmission resource unit of D2R signals, the clock information for D2R signal generation and / or transmission, and the counting unit for D2R signal generation and / or transmission time:

[0306] An AIoT device may include three types of time-domain resource units, such as: a D2R signal transmission resource unit, a clock information for D2R signal generation and / or transmission, and a counting unit for D2R signal generation and / or transmission time. The D2R signal transmission resource unit, which can be called a D2R chip, is the basic unit for D2R information transmission. The clock for D2R signal generation and / or transmission can be the smallest time unit maintaining the overall timing of the AIoT device; this clock can be consistent with the sampling frequency of the D2R signal or with the signal transmission time unit. The counting unit can count, receive, and / or transmit signals based on the D2R chip and / or the AIoT device clock. The relationship between these three time-domain resource units can be simplified to the same frequency, or each of them can be different. Figure 7 is a schematic diagram of the relationship between the three time-domain resource units.

[0307] The relationships between these three types of time-domain resource units can be one or more of the following:

[0308] Scenario 1: Internal maintenance clock of the equipment. This clock is the smallest time unit. The D2R information transmission resource unit and / or counting unit are multiples of this clock. The specific multiple relationship can be predefined by the protocol or specifically carried / indicated by the R2D signal.

[0309] For example: if the internal clock or sampling point frequency of the device is N1 (MHz), and the D2R signal transmission resource unit is M1 times the internal clock or sampling point frequency of the device, and is carried by the R2D signal, then the length of the D2R signal transmission resource unit is 1 / (N1*M1) seconds.

[0310] Scenario 2: The device clock will be adjusted to the target clock frequency or sampling point frequency based on the specific information carried / indicated by the R2D signal. The D2R information transmission resource unit and / or counting unit can be indicated separately by the R2D signal;

[0311] For example: if the default clock or sampling point frequency inside the device is N (MHz), and the R2D signal carries the target clock frequency or sampling point frequency as the default frequency of M2 times or 1 / M2, then the device will adjust the clock frequency or sampling point frequency to the target value N*M2 or N / M2.

[0312] Scenario 3: At least two of the following are the same: the transmission resource unit of the D2R signal, the clock for generating / transmitting the D2R signal, and the AIoT device counter.

[0313] For example, the transmission resource unit and the counting unit of a D2R signal are of the same length, which can be a multiple of the device clock. Alternatively, the transmission resource unit, the counting unit, and the device clock of a D2R signal are of the same length.

[0314] In addition, the transmission resource unit (CRU) for a D2R signal can be at least one of the following: the length of each bit in the information bits of the D2R signal, the length of each bit in the bit information after CRC addition to the D2R signal, the length of each encoded bit in the encoded bit information, or the length of the bit corresponding to each modulation adjustment symbol. The length of the CRU for a D2R signal can also correspond to the length of the time slot, subframe, or frame of the D2R signal.

[0315] The specific generation process is shown in Figure 8. For example, the D2R information bits are N bits, such as 110…101. The CRC check bits are 6 bits or 16 bits, which can be generated according to a polynomial. After adding the CRC, it becomes K+6 or K+16 bits.

[0316] The transmission resource unit of a D2R signal can be the information bit of D2R or the length of each bit in the bit information after CRC is added, that is, the length corresponding to the information bit "1" or "0".

[0317] If Manchester encoding is used, information bit "0" corresponds to "01", information bit "1" corresponds to "10", and the transmission resource unit length of the D2R signal corresponds to the symbol length after Manchester encoding. Therefore, 1 information bit corresponds to 2 transmission resource units. As shown in Figure 9.

[0318] If FM0 encoding (as shown in Figure 10) or Miller encoding (as shown in Figure 11) is used, the transmission resource unit length of the D2R signal corresponds to half the length of the information bits "1" or "0" after encoding.

[0319] If forward error correction codes, such as Polar or convolutional codes, are used, the transmission resource unit length of the D2R signal corresponds to one encoded bit length.

[0320] If 2^M modulation is used, the transmission resource unit length of the D2R signal corresponds to the length of the modulation symbol. For example, using OOK modulation, where bit "1" corresponds to a high level and "0" corresponds to a low level or no signal transmission, the transmission resource unit length of the D2R signal corresponds to the length of the high level, low level, or no transmission time for each bit. Using QPSK modulation, where every 2 bits are modulated into 1 modulation symbol, the transmission resource unit length of the D2R signal corresponds to the time length occupied by one modulation symbol.

[0321] Example 2: Control information carried in R2D signals:

[0322] When the R2D signal includes at least R2D control information, in this embodiment, the control information in the R2D signal carries relevant information about the D2R first time unit. The first time unit includes at least one of the following: a transmission resource unit for generating and / or transmitting the D2R signal, clock information for generating and / or transmitting the D2R signal, and a counting unit for the generation and / or transmission time of the D2R signal. Here, taking the D2R first time unit as an example of a D2R information transmission resource unit, it is referred to as a D2R chip.

[0323] The specific implementation process may include the following:

[0324] The protocol predefines and / or preconfigures one or more D2R transmission resource information, wherein the D2R signal transmission resource information includes the length information of the D2R chip. Different D2R chip lengths can correspond to different D2R payloads, different D2R information types, different device types, or different device capabilities.

[0325] The read / write device sends R2D information, and the R2D signal includes at least R2D control information. This R2D control information includes D2R chip-related information.

[0326] Method 1: The D2R chip length is determined by the D2R chip indication information carried in the R2D control information in the R2D signal.

[0327] Here, the D2R chip length indication information can be at least one of the following:

[0328] Option 1: Specific indication of the D2R chip length, or related index value;

[0329] For example, the protocol pre-limits or pre-configures N D2R chips of different lengths, and the R2D signal carries the target D2R chip length information;

[0330] Option 2: D2R information type indication information, different D2R information types correspond to different D2R chip lengths;

[0331] For example, based on different D2R information types, N D2R chip lengths are predefined or preconfigured, with one D2R chip length corresponding to one D2R information type. The R2D control signaling indicates the specific D2R information type, such as: long D2R information, medium D2R information, short D2R information, etc., corresponding to D2R chip length #1, D2R chip length #2, and D2R chip length #3, respectively.

[0332] Option 3: D2R clock length / sampling frequency indication information. There is a certain correlation between the D2R clock and the D2R chip.

[0333] For example, there is a specific relationship between the clock frequency / sampling frequency of different D2Rs and different D2R chips. For instance, the length of a D2R chip is N times the clock frequency / sampling frequency of the D2R. The length of a D2R chip can be obtained by using the clock length / sampling frequency indication information of the D2R through R2D.

[0334] Method 2: The R2D signal carries the connection time of the D2R signal. The device determines the target D2R chip based on the connection time, payload, or information type of the D2R signal.

[0335] For example, if the duration of the D2R signal carried in the R2D signal is T and the payload length of the D2R information is n bits, then the device can know the length of the D2R chip corresponding to the duration, such as T / n.

[0336] For example, if the duration of the D2R signal carried in the R2D signal is T, the device will determine the length of the D2R chip based on the information type of the D2R information.

[0337] AIoT devices determine the chip length of D2R based on the D2R chip information carried in the R2D signal.

[0338] AIoT devices carry the D2R chip length via D2R preamble.

[0339] Example 3: R2D-based preamble carrying:

[0340] When the R2D signal includes at least an R2D preamble, in this embodiment, the preamble in the R2D signal carries relevant information about the first D2R time unit. The first time unit includes at least one of the following: a transmission resource unit for the generation and / or transmission of the D2R signal, clock information for the generation and / or transmission of the D2R signal, and a counting unit for the generation and / or transmission time of the D2R signal. Here, taking the first D2R time unit as an example of a D2R information transmission resource unit, it is referred to as a D2R chip.

[0341] The specific implementation process is as follows:

[0342] When an AIoT device receives an R2D signal, it obtains the first time unit information of D2R based on the R2D preamble in the R2D signal. The D2R chip can be determined by the read / write device or by the device itself. Specific examples are as follows:

[0343] Method 1: The length of the D2R chip is determined by the read / write device and carried via the R2D preamble, including at least one of the following:

[0344] Alt1: The length of the R2D chip carried by the R2D preamble is equal to or related to the length of the D2R chip, such as the D2R chip being N times or 1 / N the length of the R2D chip, as shown in Figure 12.

[0345] Alt2: The R2D preamble carries independent D2R chip information, as shown in Figure 13. This D2R chip can be the target D2R chip length or the common chip length for D2R. The common chip length can be the default chip length or the base chip length. The common chip length here can also be the D2R clock length.

[0346] Alt3: R2D preamble and R2D together carry the length of the D2R chip. R2D preamble carries the common chip length or the basic or minimum chip length, while R2D signaling carries another part of the relevant information.

[0347] For example, the R2D preamble carries the common chip length of the D2R chip, or the default chip length, or the basic chip length, or the D2R clock length. The specific relationship between the D2R chip length and the D2R chip length carried in the R2D preamble can be carried by R2D signaling or defined by the protocol, as shown in Figure 14.

[0348] Method 2: The R2D preamble carries the common chip length, default chip length, basic chip length, or D2R clock length of the D2R chip. The D2R chip length is carried through the R2D preamble, and the device determines the target D2R chip.

[0349] Method 3: The first field in the R2D preamble, such as the R2D clock acquisition field, carries the corresponding D2R chip length for different patterns. This can be at least one of the following: a common chip length, a default chip length, a basic chip length, a D2R clock length, or a target D2R chip length. Different patterns correspond to different D2R chip lengths based on protocol pre-defined or device pre-configured information. The D2R chip length here is merely an example of the transmission resource unit length of the D2R signal.

[0350] AIoT devices determine the D2R chip length based on at least one of the following pieces of information and include it in the D2R preamble:

[0351] R2D preamble;

[0352] R2D signaling includes: D2R message payload, message type, etc.;

[0353] D2R payload;

[0354] Device capabilities;

[0355] D2R information type.

[0356] AIoT devices send the target D2R chip length to the read / write device via D2R preamble and / or D2R control information.

[0357] Example 4: Data Information Carrying Based on R2D:

[0358] When the R2D signal includes at least R2D data, in this embodiment, the preamble in the R2D signal carries relevant information about the first D2R time unit. The first time unit includes at least one of the following: a transmission resource unit for the generation and / or transmission of the D2R signal, clock information for the generation and / or transmission of the D2R signal, and a counting unit for the generation and / or transmission time of the D2R signal. Here, taking the first D2R time unit as an example of a D2R information transmission resource unit, it is referred to as a D2R chip.

[0359] The specific implementation process is as follows:

[0360] Based on the R2D signal sent by the reader / writer, the AIoT device can determine the R2D signal information type and the D2R chip length. For example, when the reader / writer sends R2D data as a command message, the device uses D2R chip length #1 for transmission, where the chip length is related to the D2R payload. When the reader / writer sends R2D data as a D2R response message, the AIoT device uses D2R chip length #2 for transmission, where D2R chip length #2 can be m times or 1 / m of D2R chip length #1, where m can be a positive integer.

[0361] AIoT devices send the target D2R chip length to the read / write device via D2R preamble and / or D2R control information.

[0362] In this embodiment, the transmission resource information of D2R signals in the AIoT system may require at least one D2R transmission resource, which is associated with the data type and device type of D2R. This disclosure proposes a method for determining and indicating the target resource (target transmission resource) to make D2R transmission more flexible.

[0363] The method and apparatus are based on the same disclosed concept. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.
