If the name of the core network equipment mentioned in the embodiments of this application changes in subsequent protocol versions (e.g., 6G), it is also within the scope of protection of this application.

[0042] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0043] In this application embodiment, the device can be an Internet of Things (IoT) device, such as an Ambient IoT (A-IoT) device. The A-IoT device can be characterized based on its energy storage capacity and its ability to generate and transmit radio frequency signals. A-IoT devices include the following types:

[0044] Device 1: No energy storage, no independent signal generation / amplification, i.e., backscatter transmission.

[0045] Device 2a: It has energy storage but no independent signal generation, i.e., backscatter transmission. The use of the stored energy may include amplification of the reflected signal.

[0046] Device 2b: It has energy storage and independent signal generation, i.e., an active radio frequency component for transmission.

[0047] Devices with different energy storage capacities also affect their transmission quality. Generally, devices with higher energy storage capacity also mean higher receiving sensitivity or higher transmitting power, and the reliability of the receiving or transmitting link can be better guaranteed.

[0048] A-IoT can be deployed in various scenarios, and two of them are introduced below.

[0049] As shown in Topology 1 of Figure 2, in this scenario, A-IoT base stations (BS) and A-IoT devices communicate directly to transmit A-IoT data and signaling. The base station sending A-IoT R2D transmissions (also known as R2D signals) and the base station receiving A-IoT D2R transmission signals can be the same or different.

[0050] As shown in Topology 2 of Figure 3, in this scenario, the AI ​​IoT BS communicates with A-IoT devices through intermediate nodes. These intermediate nodes can be terminals, repeaters, relays, or Integrated Access and Backhaul (IAB) nodes. The BS can control the intermediate nodes via air interface signaling or other interfaces; for example, the BS can control the terminals through the NR Uu air interface.

[0051] In some embodiments, A-IoT command types include inventory and command;

[0052] Inventory is the most basic and important business of A-IoT, which enables A-IoT servers to learn about one or more known or unknown A-IoT devices within the coverage area of ​​the reader via the 3GPP network.

[0053] After learning that an A-IoT device has been identified by the network, the A-IoT server may be able to issue commands to the device via the network, such as those shown in Table 1 below:

[0054] Table 1:

[0055] In some embodiments, the main data / service types of A-IoT include:

[0056] Device-originated (DO) devices typically send various data, requests, or instructions, meaning they are initiated by the device itself.

[0057] Device-terminated (DT) devices typically receive instructions, data, or requests from other devices or systems, thus terminating their connection to the device.

[0058] DO and DT data indicate that the data stream originates from or is transmitted to an A-IoT device (similar to a Radio Frequency Identification (RFID) tag). For data streams originating from A-IoT devices, i.e., DO data, further classification is as follows:

[0059] Device-originated access (DOA) means that the device autonomously initiates data transmission. For example, it connects a large number of various sensors, which collect and proactively report information about the environment, the device, and the organism when necessary.

[0060] Device-originated–device-terminated triggered (DO-DTT) means that data transmission is triggered by the termination of data. Examples include asset identification, status reporting, and tracking, all of which involve downlink-triggered reporting. The reader collects data from the tag by triggering an inventory procedure. Since the data is generated / initiated within the A-IoT device, this service should be considered as a DO service triggered by a command sent by the reader.

[0061] In some embodiments, the general A-IoT process is shown in Figure 4, including the following steps:

[0062] Step A, A-IoT paging, is when the reader sends an A-IoT paging message to the device;

[0063] Step B, Access, Device-to-Reader D2R data transmission, including D2R data transmission, and may also include A-IoT random access procedure;

[0064] Step C: Interaction of possible commands and responses from higher layers after access; such as possible R2D transmission, where the reader / writer transmits commands from higher layers after access, and / or possible D2R transmission, where the device transmits commands in response.

[0065] The inventory-only process includes: Step A + Step B;

[0066] The inventory and command process includes: Step A + Step B + Step C.

[0067] The information sending method, information receiving method, apparatus, reader, and device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0068] Please refer to Figure 5, which is a flowchart of an information sending method provided in an embodiment of this application. As shown in Figure 5, it includes the following steps:

[0069] Step 501: The reader sends first R2D information, which is used to indicate transmission parameters. The transmission parameters are used to determine multiple transmission resources. The transmission resources are used to transmit first data, which includes at least one of R2D data and D2R data.

[0070] The aforementioned reader / writer can be a terminal or a network-side device. The aforementioned device can be an Internet of Things (IoT) device, such as an A-IoT device, a tag device, or a terminal, etc.

[0071] In this embodiment, R2D information refers to the information sent by the reader to the device, also known as R2D signaling, R2D signal, or R2D transmission; R2D data refers to the data sent by the reader to the device, also known as R2D transmission or R2D signal; D2R data refers to the data sent by the device to the reader, also known as D2R transmission or D2R signal.

[0072] The R2D information mentioned above can be an explicit or implicit indication of the aforementioned transmission parameters.

[0073] The aforementioned transmission parameters are used to determine multiple transmission resources. This could mean that the transmission parameters indicate the multiple transmission resources, or that the transmission parameters correspond to the multiple transmission resources, and the device can determine the multiple transmission resources based on the aforementioned transmission parameters.

[0074] The aforementioned multiple transmission resources are used for multiple first data transmissions or for multiple first data transmissions.

[0075] The aforementioned first data, including at least one of R2D data and D2R data, can be understood as follows: the first data used for transmission by the aforementioned plurality of transmission resources can include both D2R data and R2D data. That is, the multiple first data corresponding to the aforementioned plurality of transmission resources can include either D2R data or R2D data; or, the first data used for transmission by the aforementioned plurality of transmission resources are all D2R data, or the first data used for transmission by the aforementioned plurality of transmission resources are all R2D data. Furthermore, in the case of transmitting multiple D2R data, these multiple D2R data can carry the same information or different information; similarly, in the case of transmitting multiple R2D data, these multiple R2D data can carry the same information or different information.

[0076] For D2R data, the above-mentioned transmission resources used for transmitting the first data means that the transmission resources are used for the device to send D2R data and for the reader to receive D2R data; for R2D data, the above-mentioned transmission resources used for transmitting the first data means that the transmission resources are used for the device to receive R2D data and for the reader to send R2D data.

[0077] The aforementioned transmission resources may be used to transmit the first data, but whether the first data is actually transmitted is determined by the device or reader. For example, for D2R data, when there is a demand for D2R data transmission, D2R data is sent based on the corresponding transmission resources. That is, the aforementioned multiple transmission resources can be understood as alternative transmission resources.

[0078] In this embodiment of the application, since the transmission parameters are used to determine multiple transmission resources, one-to-many scheduling is achieved, thereby reducing signaling overhead. That is, it has the characteristics of one-time allocation and multiple uses. For example, the transmission parameters of multiple D2R data can be scheduled by one R2D information.

[0079] As an optional implementation, the method further includes at least one of the following:

[0080] The reader receives D2R data sent by the device on one of the aforementioned multiple transmission resources;

[0081] The reader sends R2D data to the device on one of the aforementioned multiple transmission resources.

[0082] This can improve data transmission performance.

[0083] As an optional implementation, the transmission parameters include at least one of the following:

[0084] Transmit time window information;

[0085] Information about the transmission resources within the transmission time window;

[0086] The type of the first data includes at least one of Device Termination (DT) and Device Autonomous Initiation of DO-A;

[0087] The identifier of the device corresponding to the transmission parameters;

[0088] The time information of the next first R2D information.

[0089] The aforementioned transmission time window may include all or part of the transmission resources mentioned above.

[0090] The information of the aforementioned transmission time window can be information used to indicate the aforementioned transmission resource window, that is, the transmission time window is determined based on this information.

[0091] In some implementations, the aforementioned transmission time window may also be a transmission time window agreed upon by the protocol, or a transmission time window pre-configured for the device, that is, the aforementioned first R2D information may not indicate the information of the aforementioned transmission time window.

[0092] In some implementations, the information of the aforementioned transmission time window includes at least one of the following:

[0093] The start time of the transmission time window;

[0094] The size of the transmission time window;

[0095] The end time of the transmission time window;

[0096] The period of the transmission time window.

[0097] The transmission time window can be flexibly configured using the information provided, making the transmission between the device and the reader more flexible.

[0098] In some implementations, the information of the transmission time window may include at least one of the above-mentioned features, which may be agreed upon by the protocol or pre-configured by the network-side device.

[0099] The information of the transmission resources within the aforementioned transmission time window can be information used to indicate the multiple transmission resources within the aforementioned transmission time window, so that the transmission resources within the transmission time window can be determined through this information.

[0100] In some implementations, the information of the transmission resources within the transmission time window can also be agreed upon by the protocol. For example, when the transmission time window is configured in the first R2D information, the protocol agrees that multiple transmission resources within the transmission time window are the multiple transmission resources, that is, the first R2D information may not indicate the information of the transmission resources within the transmission time window.

[0101] In some implementations, the information of the transmission resources within the aforementioned transmission time window includes at least one of the following:

[0102] The time-domain information of the transmission resources within the transmission time window;

[0103] Frequency domain information of the transmission resources within the transmission time window;

[0104] The code field information of the transmitted resources within the transmission time window;

[0105] The period of the transmission resource within the transmission time window.

[0106] The transmission resources within the aforementioned transmission time window can be flexibly configured using the information of the transmission resources within that time window, making the transmission between the device and the reader more flexible.

[0107] In some implementations, the information of the transmission resources within the aforementioned transmission time window, including at least one of the above-mentioned items, may also be agreed upon by the protocol or pre-configured by the network-side device.

[0108] The above types include at least one of DT and DO-A, that is, the first data can be data of type DT or data of type DO-A, so that different types of data transmission can be realized.

[0109] It should be noted that, when only the type of the first data is included, multiple transmission resources can be determined based on the type of the first data and the preset relationship between multiple transmission resources.

[0110] In some implementations, the type of the first data mentioned above may also be agreed upon by a protocol or pre-configured.

[0111] The identifier of the device corresponding to the above transmission parameters can be the identifier of the device using the above transmission parameters, that is, the device corresponding to the identifier uses the transmission parameters, or the transmission parameters are only valid for the device corresponding to the identifier, and can be the identifier of one or more devices.

[0112] The aforementioned identifier can be a device-specific ID, an identifier for a group of devices, or an identifier for all devices under the reader's coverage.

[0113] The aforementioned identifiers allow specific devices to use the aforementioned transmission parameters, making the transmission parameter indications more accurate.

[0114] In some implementations, the aforementioned identifier may not be sent. For example, by default, any device that receives the aforementioned first R2D information may use the aforementioned multiple transmission resources.

[0115] It should be noted that, when only the identifier of the device corresponding to the transmission parameters is included, multiple transmission resources can be determined based on the preset relationship between the identifier and multiple transmission resources.

[0116] The time information of the next first R2D information mentioned above may include the period and the time position of the first R2D information transmission within that period. Furthermore, the next first R2D information may be the same as or different from the first R2D information in step 501, or may contain some identical content.

[0117] Because of the timing information indicating the next first R2D message, the device can better monitor the next first R2D message.

[0118] It should be noted that, in the case of time information including the next first R2D information, multiple transmission resources can be determined by the preset relationship of multiple transmission resources based on this time information.

[0119] In some implementations, the first data is required, expected, assumed, or tacitly assumed to be transmitted within the transmission time window; or

[0120] The first data can only be transmitted within the transmission time window; or

[0121] The first data is not required, expected, or permitted to be transmitted outside the transmission time window.

[0122] The above requirement that the first data be transmitted within the transmission time window includes:

[0123] The reader / writer sends or receives the first data within the transmission time window; or,

[0124] The reader does not send or receive the first data outside the transmission time window; or,

[0130] The reader instructs the device not to send or receive the first data outside the transmission time window; or,

[0134] The reader does not receive or send the first data outside the transmission time window; or,

[0135] The device receives or sends the first data within the transmission time window; or,

[0136] The device does not receive or send the first data outside the transmission time window; or,

[0137] If the reader receives the first data outside the transmission time window, the reader may ignore the first data or assume that the transmission parameters are misconfigured; or,

[0138] If the reader sends the first data outside the transmission time window, the device ignores the first data or assumes that the transmission parameters are misconfigured; or,

[0139] If the device receives the first data outside the transmission time window, the device ignores the first data or considers the transmission parameters to be misconfigured; or,

[0140] If the first data is sent outside the transmission time window specified by the device, the reader ignores the first data or assumes that the transmission parameters are misconfigured; or...

[0142] The reader determines whether the device sends or receives the first data during the transmission time; or,

[0146] The reader does not receive or send the first data outside the transmission time window; or,

[0147] The device receives or sends the first data within the transmission time window; or,

[0148] The device does not receive or send the first data outside the transmission time window; or,

[0149] If the reader receives the first data outside the transmission time window, the reader may ignore the first data or assume that the transmission parameters are misconfigured; or,

[0150] If the reader sends the first data outside the transmission time window, the device ignores the first data or assumes that the transmission parameters are misconfigured; or,

[0151] If the device receives the first data outside the transmission time window, the device ignores the first data or considers the transmission parameters to be misconfigured; or,

[0165] The reader only sends or receives the first data within the transmission time window; or,

[0166] The reader determines whether the device sends or receives the first data during the transmission time; or,

[0167] The reader determines whether it sends or receives the first data during the transmission time.

[0168] The above requirements, expectations, assumptions, or defaults stipulate that the first data is transmitted within the transmission time window, which allows the device and the reader to perform receiving or sending actions within the transmission time window, thereby reducing the power consumption of the device or the reader.

[0169] The transmission of the aforementioned first data can only be performed within the transmission time window, including:

[0170] The reader can only send or receive the first data mentioned above within the transmission time window;

[0171] The device can only send or receive the first data mentioned above within the transmission time window.

[0172] This allows the device and reader to only need to receive or send data within the transmission time window, thereby reducing the power consumption of the device or reader.

[0173] The above-mentioned requirement that the first data be transmitted outside the transmission time window includes:

[0174] The reader / writer sends or receives the first data within the transmission time window; or,

[0175] The reader does not send or receive the first data outside the transmission time window; or,

[0176] The reader only sends or receives the first data within the transmission time window; or,

[0177] The device sends or receives the first data within the transmission time window; or,

[0185] The above-mentioned expectation that the first data will not be transmitted outside the transmission time window includes:

[0186] The reader receives or sends the first data within the transmission time window; or,

[0187] The reader does not receive or send the first data outside the transmission time window; or,

[0188] The device receives or sends the first data within the transmission time window; or,

[0205] The reader instructs the device not to send or receive the first data outside the transmission time window; or,

[0206] The reader instructs the device to send or receive the first data only within the transmission time window.

[0207] By not requiring, expecting, or disallowing the transmission of the first data outside the transmission time window, the device and the reader can perform receiving or sending actions within the transmission time window, thereby reducing the power consumption of the device or the reader.

[0208] As an optional implementation, the device corresponding to the plurality of transmission resources includes one of the following:

[0209] A set of equipment;

[0210] All devices within the coverage area of ​​the reader / writer;

[0211] A device.

[0212] Among these, for all devices within the coverage area of ​​a group of devices or readers, the aforementioned multiple transmission resources can be contention-based resources, while for a single device, they can be contention-free resources allocated to that specific device.

[0213] In this implementation, multiple transmission resources can be allocated to a single device, a group of devices, or all devices within the coverage area, making scheduling more flexible. Furthermore, scheduling resources together for a group of devices or all devices within the coverage area can save signaling overhead.

[0214] As an optional implementation, the first R2D information is sent on demand based on at least one of the following:

[0215] Reports on business cycle, business size, or device cache status.

[0216] The aforementioned business cycle refers to the business cycle between the reader and the device, such as the DO-A business cycle or DT business cycle.

[0217] The aforementioned sending of the first R2D information on demand based on the service cycle can be done when there is a service requirement to transmit the first R2D information, or the transmission parameters indicated by the first R2D information can match the service cycle.

[0218] In this way, by sending the first R2D information on demand based on the service cycle, signaling transmission overhead can be saved, and the transmission parameters indicated by the first R2D information can be more easily matched with the service cycle, thereby improving service transmission performance.

[0219] The above-mentioned service size refers to the size of the service between the reader and the device, such as the size of DO-A service or DT service.

[0220] The aforementioned sending of the first R2D information on demand based on service size can be done when there is a service size indicating that the service needs to be transmitted, or when the transmission parameters indicated by the first R2D information match the service size.

[0221] In this way, by sending the first R2D information on demand based on the service size, signaling transmission overhead can be saved, and the transmission parameters indicated by the first R2D information can be more easily matched with the service size, thereby improving service transmission performance.

[0222] The aforementioned device-based cache status report can be sent on demand. The first R2D information can be sent when the device has cached data, or the transmission parameters indicated by the first R2D information can match the cache status report.

[0223] In this way, since the first R2D information is sent on demand based on the device's cache status report, signaling transmission overhead can be saved, and the transmission parameters indicated by the first R2D information can be more easily matched with the cache status report, avoiding the allocation of too much transmission resources and resulting in waste of transmission resources.

[0224] As an optional implementation, the method further includes:

[0225] The reader sends second R2D information, which is used for at least one of the following:

[0226] Carrying synchronization signals;

[0227] Carry a wake-up signal;

[0228] Update all or part of the transmission parameters in the transmission parameters;

[0229] Deactivate all or some of the transmission parameters in the transmission parameters;

[0230] Activate the transmission of all or part of the first data in the plurality of transmission resources;

[0231] Cancel the transmission of all or part of the first data from the plurality of transmission resources.

[0232] Sending the second R2D information can be sending one or more R2D information, and the functions of different R2D information can be the same or different, or partially the same.

[0233] The aforementioned synchronization signals allow devices to synchronize, thereby improving their transmission performance.

[0234] The aforementioned wake-up signal can wake up the device, enabling it to send or receive data in a timely manner, thereby improving the device's transmission performance.

[0235] The aforementioned updating of all or part of the transmission parameters can also be referred to as adjusting all or part of the transmission parameters. This could involve updating the transmission parameters after updating the second R2D information, or updating the transmission resources after updating the second R2D information.

[0236] Updating all or part of the transmission parameters mentioned above can dynamically update the transmission parameters indicated by the first R2D information, making the transmission between the device and the reader more flexible.

[0237] The aforementioned deactivation of all or part of the transmission parameters can be the transmission parameters after deactivating the second R2D information, such as the transmission resources after deactivating the second R2D information.

[0238] Deactivating all or some of the transmission parameters described above allows for more flexible configuration of transmission parameters.

[0239] The aforementioned activation of all or part of the transmission of the first data among the plurality of transmission resources may be achieved by activating one or more transmission resources after the device receives the first R2D information but has not yet activated them, through the second R2D information. This can make the plurality of transmission resources more reliable.

[0240] By canceling the transmission of all or part of the first data in the plurality of transmission resources, the configuration of transmission resources can be made more flexible.

[0241] In some implementations, the step of the reader sending the second R2D information includes at least one of the following:

[0242] The reader sends the second R2D information at a first time, which is X transmission time windows prior to X, where X is a positive integer.

[0243] The reader sends the second R2D information at a second time, which is after the start time of the first transmission time window in Y transmission time windows, where Y is a positive integer;

[0244] The transmission time window includes the transmission resources among the plurality of transmission resources.

[0245] The second R2D information sent in the first and second time periods can be the same or different information, or have some content that is the same. For example, the second R2D information sent in the first time period is used for synchronization or wake-up, while the second R2D information sent in the second time period is used for activation or update.

[0246] The first and second times mentioned above can be agreed upon in the protocol or configured by the network-side equipment.

[0247] In this implementation, the corresponding second R2D information can be sent at different times and locations, so that the reader can configure transmission resources more flexibly to meet the needs of more business or scenarios.

[0248] As an optional implementation, if the D2R data includes DO-A data:

[0249] Each of the first data items includes DO-A data and first indication information, wherein the first indication information is used to indicate whether there will be further DO-A data transmission; or...

[0250] The first data transmitted for the first time within N transmission time windows includes DO-A data and second indication information, or the first data transmitted for the first time within N transmission time windows includes only DO-A data; or,

[0251] The first data that satisfies the first condition for the corresponding transmission resources includes DO-A data and second indication information. The first condition includes that the transmission resources are capable of transmitting the DO-A data and the second indication information.

[0252] The second indication information is used to indicate the size of the DO-A data that the device needs to send.

[0253] The aforementioned DO-A data is a type of D2R data.

[0254] The first indication information indicates whether there will be any more DO-A data transmissions. This can refer to whether there will be any more DO-A data transmissions after the first data containing the first indication information.

[0255] In this embodiment, the first indication information indicates whether there is still DO-A data transmission. This enables the reader to receive DO-A data better and allows the reader to release relevant resources or operations in a timely manner when there is no DO-A data, thereby saving resources and power consumption of the reader.

[0256] The size of the DO-A data that the above-mentioned device needs to send can be the device's Buffer Status Report (BSR), the size of the DO-A data to be sent by the device, or the size of the first data or D2R data to be sent by the device.

[0257] Because the size of the DO-A data that the device needs to send is indicated, the reader can flexibly receive the DO-A data sent by the device based on this size, schedule the device to send DO-A data, or not schedule the device and directly receive the DO-A data sent by the device.

[0258] In addition, since the first data transmitted within N transmission time windows includes DO-A data and second indication information, the reader can know the size of the DO-A data that the device needs to send as early as possible, so that the reader can better control the transmission method of the device to send DO-A data, resulting in better DO-A data transmission performance.

[0259] The first data transmitted within N transmission time windows includes only DO-A data, which allows the device to send more DO-A data more quickly.

[0260] The aforementioned first condition, which includes the transmission resources being able to transmit the DO-A data and the second indication information, can be understood as the transmission resources corresponding to the first data being able to complete the transmission of the DO-A data and the second indication information. Conversely, for first data that does not meet the first condition, the second indication information will not be sent, and only the DO-A data will be included, in order to ensure the transmission performance of the DO-A data.

[0261] As an optional implementation, the method further includes at least one of the following:

[0262] The reader receives the first data sent autonomously by the first transmission resource in the plurality of transmission resources;

[0263] The reader / writer receives the first data from the second transmission resource receiving device among the plurality of transmission resources based on the first data scheduled by the reader / writer.

[0264] The first data sent based on the reader scheduling refers to the reader sending scheduling information to the device, and the device sending the first data based on the scheduling information.

[0265] In this implementation, two data transmission methods are supported to improve the transmission performance between the reader and the device.

[0266] In some implementations, when the first transmission resource includes at least two transmission resources, all or part of the at least two transmission resources are located before the second transmission resource.

[0267] In this embodiment, it is permissible for the device to autonomously send the first data before the device sends the first data based on the schedule, and some autonomous first data can be sent after the first data is sent based on the schedule. This allows the device to better send the first data to the reader, thereby improving the device's transmission performance.

[0268] In some embodiments, the method further includes:

[0269] The reader sends third R2D information within the transmission time window. The third R2D information is used to schedule the device to perform data transmission. The data transmission scheduled by the third R2D information occurs within or outside the transmission time window. The transmission time window includes the transmission resources among the plurality of transmission resources.

[0270] The aforementioned transmission time window may be the transmission time window indicated by the first R2D information, or, if the first R2D information does not indicate a transmission time window, it may be a transmission time window agreed upon by the protocol or pre-configured.

[0271] The data transmission performed by the aforementioned scheduling equipment may include at least one of the following:

[0272] The scheduling device sends D2R data to the reader / writer;

[0273] The scheduling device receives R2D data sent by the reader / writer.

[0274] In this embodiment, in addition to transmitting the first data based on the first R2D information, the third R2D information can also be received within the transmission time window corresponding to the first R2D information. In this way, the device only needs to remain in a wake-up state within the aforementioned transmission time window to reduce the power consumption of the device.

[0275] In this embodiment, the reader sends first reader-to-device R2D information. This first R2D information indicates transmission parameters, which determine multiple transmission resources. These transmission resources are used to transmit first data, which includes at least one of R2D data and device-to-reader D2R data. Because the transmission parameters determine multiple transmission resources, one-to-many scheduling is achieved, thereby reducing signaling overhead.

[0276] Please refer to Figure 6, which is a flowchart of an information receiving method provided in an embodiment of this application. As shown in Figure 6, it includes the following steps:

[0277] Step 601: The device receives first reader-to-device R2D information sent by the reader. The first R2D information is used to indicate transmission parameters.

[0325] The device cancels or deactivates the third transmission parameter in the transmission parameters corresponding to a time after the first time or the second time based on the second R2D information.

[0326] The aforementioned transmission parameter corresponding to a time after the first time or the second time can refer to the time at which the transmission parameter applies after the first time or the second time, such as updating the location of transmission resources after the first time or the second time.

[0331] The R2D information received by the aforementioned device may be the first R2D information mentioned above, or R2D information other than the first R2D information, such as R2D information used to schedule the device to receive the second R2D information mentioned above.

[0332] By listening within the listening window or by listening to instructions on R2D information already received by the device, power consumption of the device can be saved.

[0333] Optionally, upon receiving the second R2D information, the device receives or transmits the first data using one of the plurality of transmission resources; or

[0334] If the device has the first data in its cache, the first data is transmitted through one of the plurality of transmission resources.

[0335] When the device receives the second R2D information, it may receive or send the first data in the transmission resources among the plurality of transmission resources only after receiving the second R2D information. This allows the device and the reader to better achieve consistency in the transmission of the first data, thereby improving the transmission performance between the device and the reader.

[0336] Sending the first data through one of the plurality of transmission resources when the device has the first data in its cache allows the device to send data only when needed, thereby saving device power consumption and transmission resources.

[0347] Sending the first data using a contention-based resource among the plurality of transmission resources, or sending or receiving the first data based on the transmission parameters, can improve the transmission performance of the device.

[0359] It should be noted that this embodiment is an implementation of the device corresponding to the embodiment shown in FIG5. For the specific implementation, please refer to the relevant description of the embodiment shown in FIG5. In order to avoid repeated description, this embodiment will not be repeated.

[0360] The following uses an A-IoT device as an example to illustrate the method provided in the embodiments of this application:

[0361] This application provides an embodiment in which a first R2D information can schedule or configure the transmission parameters of multiple first data, such as multiple first data corresponding to the multiple transmission resources mentioned above. The multiple first data may carry the same information or different information.

[0362] In some implementations, the above transmission parameters include at least one of the following:

[0369] The time for transmitting the next first R2D message includes at least the period and the time position of the first R2D transmission within that period.

[0370] The aforementioned transmission resources can be resources that are subject to contention among all devices within a group of devices or the coverage area of ​​a Reader (Contention-based) or resources that are subject to contention-free allocation to a specific device.

[0371] In some implementations, the device should be in an active, wake-up, or on-time state, hereinafter referred to as "on," at least during the transmission time window. The device's behavior during the transmission time window includes at least one of the following:

[0379] During the second time period after the start of each Y (Y>=1) transmission time window, the device listens for the second R2D information.

[0380] The functions or information carried by the two second R2D information can be the same or different.

[0381] In some implementations, the second R2D information or signal is used for at least one of the following:

[0382] The device carries a synchronization signal; upon receiving the synchronization signal, it synchronizes itself.

[0383] Carrying a wake-up signal, after receiving the wake-up signal, the device enters the on state after time T3, receives the synchronization signal from R2D, and performs synchronization;

[0384] Update / adjust one or more transmission parameters of the first data in a certain Z transmission time window within subsequent or associated X or Y time windows, where 1≤Z≤X and 1≤Z≤Y;

[0385] Cancel or activate the transmission of the first data in a certain Z transmission time window within a subsequent or associated X or Y time window, where 1≤Z≤X and 1≤Z≤Y;

[0386] Deactivate or deactivate all transmission parameters of the DO-A configured for the first R2D information or signal.

[0387] The first and second times mentioned above are specified by the agreement or indicated by the first R2D information or signal.

[0388] The above X, Y and Z are specified by the protocol or indicated by the first R2D information or signal.

[0389] In some implementations, the device's act of listening to the second R2D information before transmitting or receiving the first data within the transmission time window further includes at least one of the following:

[0390] The device can only transmit or receive the first data within the transmission time window if it receives the second R2D information indication.

[0391] The device continuously listens for second or third R2D information; or

[0392] The device listens for second R2D information within a first listening window specified in the protocol or configured or indicated by the first R2D information; or

[0393] The device decides whether to listen based on the most recent R2D information or signal. That is, the most recent R2D information or signal indicates whether the device needs to listen for the second R2D information before transmitting or receiving the first data within the transmission time window.

[0394] The device determines whether the first data is in the cache. If it is, it transmits the data according to the configuration or scheduling information of the most recent first data transmission parameters. That is, the device does not require that it can only transmit or receive the first data within the transmission time window after receiving the second R2D information indication.

[0395] In some implementations, if the device does not receive a second R2D information indication, the device's behavior further includes at least one of the following:

[0396] The device enters sleep mode or power-saving mode;

[0397] The device needs to be put into the ON state;

[0398] The device does not transmit the first data;

[0399] The device uses contention-based resource transmission for the first data, or the device transmits data based on the configuration or scheduling information of the most recent first data transmission parameters.

[0400] In some implementations, when the first data type is DO-A, the first transmission of the first data within every N (N>=1) transmission time window should at least include information about the size of the DO-A data that the device needs to send (referred to as BSR).

[0401] In some implementations, if the resources of the first data transmitted initially can transmit the full amount of DO-A data that the device needs to send without including the BSR, then the first data transmitted initially may not include the BSR.

[0402] In some implementations, the first data transmission can be a device-initiated autonomous transmission or a reader-scheduled transmission.

[0403] In some implementations, within the transmission time window, the first data transmitted in the first M times (M>=1) is autonomously transmitted by the device, and the subsequent first data can be transmitted by the reader-scheduled transmission, that is, the transmission mode of the first data can be switched (from autonomous transmission initiated by the device to data transmission triggered by the reader-scheduled A-IoT device).

[0404] In some implementations, when a device receives an R2D scheduling or instruction from a reader to perform R2D reception or D2R transmission within the transmission time window, the R2D reception or D2R transmission may occur outside the transmission time window. In such cases, the device is required to be in the on state at least during the R2D reception or D2R transmission period to complete the R2D reception or D2R transmission.

[0405] In some implementations, the reader can send the third R2D information at any time within the transmission time window or when the device is in the on state. Alternatively, if the device detects the second R2D information within the transmission time window, it can perform at least one of the following actions according to the instructions of the second R2D information:

[0406] Update or adjust one or more transmission parameters of the first data in a certain Z transmission time window within the time window of the subsequent X or Y periods within the current period, or excluding the current period.

[0407] Cancel or activate the transmission of the first data in a certain Z transmission time window within the current period, or within X or Y subsequent periods excluding the current period;

[0408] Activate or release all transmission parameters of the DO-A configured in the first R2D information.

[0409] This application provides an embodiment, which mainly describes the transmission parameters of the first R2D information scheduling or configuration DO-A data.

[0410] The main idea of ​​this embodiment is that the reader sends the scheduling or configuration information of the transmission parameters of DO-A data as needed, and the device listens to the scheduling or configuration information of the transmission parameters of DO-A data sent by the reader.

[0411] In some implementations, the reader transmits scheduling or configuration information for the transmission parameters of DO-A data on demand, based on the DO-A service type and the devices supporting that service class; this is the aforementioned first R2D information. One scenario is that the reader's first R2D information for the scheduling or configuration of DO-A data transmission parameters is periodic. This periodic information can be indicated by other R2D information, or it can be indicated by the current first R2D information. Another scenario is that the reader, while currently transmitting the scheduling or configuration information for the transmission parameters of DO-A data, indicates the time for the next transmission of the scheduling or configuration information for the transmission parameters of DO-A data.

[0412] For example, device #1 supports DO-A service type 1 (DO-A#1 for short), and device #2 supports DO-A service type 2 (DO-A#2 for short). The Reader indicates the transmission parameters for DO-A #1 and DO-A#2 respectively, as shown in Figure 7:

[0413] The transmission time window T1 of DO-A#1, the period P1, the start time of T1 at P1, the start time of P1, and the specific resources of DO-A#1 within the transmission time window;

[0414] The transmission time window T2 of DO-A#2, the period P2, the start time of T2 at P2, the start time of P2, and the specific resources of DO-A#2 within the transmission time window.

[0415] In this case, specific DO-A resources within the transmission time window may not be configured. In this case, the reader / writer is required to perform blind detection of DO-A data; or

[0416] If only the start position of the DO-A resource is configured within the transmission time window, without configuring its end position or transmission duration, then the reader performs blind detection of the DO-A data before and after the configured start position of the DO-A resource. Before or after the start position of the DO-A resource, the maximum sampling frequency offset (SFO) on the device side needs to be considered for detection.

[0417] In some implementations, when transmitting DO-A data, the device may transmit at least synchronization information or sequence information or information required to demodulate DO-A data, such as the DO-A data size, reference sequence information carried in the data, which is used for synchronization or channel estimation to help the reader determine whether a DO-A service is being transmitted or to detect or receive a DO-A service.

[0418] In some implementations, devices #1 and #2 determine their own associated transmission time windows.

[0419] One approach is to use a reader to indicate which device IDs or device group IDs can use DO-A#1 or DO-A#2.

[0420] Another approach is implicit determination, such as establishing a connection between device ID and DO-A transmission parameters. For example, if the network is configured with transmission parameters for two DOA data, denoted as N=2, with DOA indices n0=0 and n1=1, the device with device ID=3 determines that it can use the DOA with DOA index=1 by using (device ID) mod N=1; the device with device ID=1 determines that it can use the DOA with DOA index=1 by using (device ID) mod N=1; and the device with device ID=2 determines that it can use the transmission parameters of the DOA with DOA index=0 by using (device ID) mod N=0.

[0421] The following explanation uses DO-A#1 as an example; the same applies to DO-A#2.

[0422] Device #1 has DO-A#1 service. Based on the DO-A#1 transmission parameters and configuration, it will send one or more different DO-A#1 data within time window T1. If Device #1 is not scheduled to perform R2D reception or D2R transmission outside time window T1, it can sleep to save power. If Device #1 still has DO-A#1 service, it is required that Device #1 be in the on state at least at the beginning of time window T1 of the next cycle P1 of DO-A#1, and send D2R data for DO-A#1. Otherwise, if Device #1 does not have DO-A#1 service, then:

[0423] Device #1 is not required to be in the on state in the next cycle P1 of DO-A#1, or in other words, device #1 can sleep in the next cycle P1 of DO-A#1 to save power; or

[0424] Device #1 is required to be in the on state at the beginning of at least time window T1 in the next cycle P1 of DO-A#1 so as to receive the reader's R2D scheduling until it receives a signal from the reader instructing the device to sleep or the time window T1 expires, at which point device #1 enters the sleep state.

[0425] This application provides an embodiment, which mainly describes the scheduling or configuration information for dynamically enabling or updating the transmission parameters of DO-A data.

[0426] The main idea of ​​this embodiment is: the first R2D information configures the transmission parameters of DO-A data, but R2D information (such as the second R2D information in the above embodiment) is also needed to activate the transmission parameters of DO-A data before the device can transmit DO-A data; activating the transmission parameters of DO-A data also includes updating and supplementing the transmission parameters of DO-A data. For example:

[0427] One example is that the first R2D information configures all the transmission parameters of DO-A data, and the second R2D information is used to activate the transmission parameters of DO-A data in the current period transmission time window, or in the subsequent X periods (e.g., X=2) associated with the third R2D information, such as activating all or part of the transmission resources of DO-A data in the current period or the next two periods. Accordingly, if the device does not receive the second R2D information, it will not send DO-A data.

[0428] Another example is that the first R2D information configures some transmission parameters of the DO-A data, and the second R2D information supplements other transmission parameters of the DO-A data; for example, the first R2D information only configures the period and size of the transmission time window of the DO-A data, while the second R2D information indicates or configures the starting position of the transmission time window of the DO-A data in a period, and the specific time domain, frequency domain or code domain resources of the DO-A data in a transmission time window.

[0429] Another example is that the first R2D information configures all transmission parameters for the DO-A data, and the second R2D information can update all or part of the transmission parameters configured in the first R2D information for the DO-A data; for example, the first R2D information configures the transmission time window period for the DOA data to be 200ms, and the transmission time window size to be 100ms. Based on the obtained DOA BSR information, the reader updates the transmission time window for the DOA data in the second R2D information to 50ms (shortened from 100ms to 50ms, corresponding to a smaller or reduced amount of DOA data in the BSR) or to 150ms (extended from 100ms to 150ms, corresponding to a larger or increased amount of DOA data in the BSR).

[0430] The main idea of ​​another embodiment is: the first R2D information configures the transmission parameters of DO-A data. If the second R2D information is not received before the DO-A data transmission resource configured in the first R2D information or within the time specified by the protocol or indicated by the first R2D information (such as the first time and the second time in the above embodiment), the device transmits DO-A data according to the configuration information of the first R2D information; otherwise, if the second R2D information is received before the DO-A data transmission resource configured in the first R2D information or within the time specified by the protocol or indicated by the first R2D information (such as the first time and the second time in the above embodiment), the device transmits DO-A data according to the indication, configuration, or scheduling of the second R2D information.

[0431] Example 4:

[0432] This embodiment mainly describes the switching of DO-A service scheduling mode (from device autonomy to reader scheduling).

[0433] The main idea of ​​this embodiment is that after receiving a DOA data from a device, the reader can send an R2D scheduler to transmit D2R data for the DO-A, or switch the D2R data of the DO-A to D2R data transmission for DO-DTT. The R2D scheduler further indicates the transmission parameters of the D2R data; if the R2D scheduler does not indicate one or more transmission parameters for the D2R data transmission, then the D2R data transmission parameters use the protocol-predefined parameters or the transmission parameters of the DO-A D2R data transmitted autonomously by the device most recently.

[0434] In one implementation, the protocol specifies or the first R2D information indicates that the first DO-A data in each cycle or every X transmission windows, such as X = 2 cycles, should carry at least DOA BSR information.

[0435] In another implementation, the device decides whether to carry the BSR information of the DOA in the current or first DOA data transmission. For example, one implementation is that the device always carries the BSR information of the DOA, while another implementation is that if the remaining resources after transmitting the current or first DOA data can still carry the DOA BSR, then the device carries the BSR information in the DOA data transmission; otherwise, if the remaining resources after transmitting the DOA data are insufficient to carry the DOA BSR, then the device does not carry the BSR information in the DOA data transmission.

[0436] Another implementation method determines whether to carry DOA BSR information based on conditions. For example, if the current DOA resource can transmit all the DOA data, then the current DOA data transmission does not carry DOA BSR information; if the current DOA resource cannot transmit all the DOA data, then the current DOA data transmission needs to carry DOA BSR information.

[0437] In another implementation, each DOA data transmission carries a message indicating whether there will be any more DOA transmissions.

[0438] Based on DOA BSR information, for example, if the BSR information indicates that there is still DOA data to be transmitted on the device side, the reader can decide to schedule the subsequent DOA data, that is, the transmission of subsequent DOA data is scheduled by R2D.

[0439] In another implementation, the reader can request the device to send DOA BSR information, such as sending R2D information. This R2D information explicitly instructs the device to transmit the DOA BSR, and then the reader determines whether the subsequent transmission of DOA data is scheduled by R2D based on the DOA BSR information.

[0440] In another implementation, DO-A retransmission is scheduled by R2D. That is, if the device transmits DO-A data #1, but demodulation fails on the reader side, the reader sends an R2D to trigger the device to retransmit DO-A data #1.

[0441] It should be noted that the above embodiments are illustrated using DOA service as an example, but they are also applicable to DT and DO-DTT services. That is, if the D2R transmission is of the DT or DO-DTT type, multiple D2R transmission parameters can be allocated by one R2D, allocated once and used multiple times.

[0442] The embodiments of this application support the transmission of DOA services and can achieve the following:

[0443] Assigning transmission parameters for DOA services features a one-time allocation and multiple uses. That is, multiple D2R transmission parameters can be scheduled by a single R2D. This reduces signaling overhead, and the device can autonomously transmit DO-A services.

[0444] The device autonomously initiates the allocation of resources for data transmission (such as the allocation of transmission resources for DOA data);

[0445] Based on the characteristics of known DOA services (such as those from the AIoT application layer or supporting the AIoT core network), including service cycle and service size, the reader directly allocates DOA resources; or the reader allocates DOA data transmission resources based on the buffer status report of the DOA service reported by the device.

[0446] Regarding the transmission resources allocated to DOA, the resource selection method includes selecting resources using either a contention-based or contention-free approach;

[0447] Device sleep and wake-up, as well as monitoring behaviors, include the following:

[0448] Configure or indicate operating modes or discontinuous reception modes for the device, including the period of the mode, the wake-up or active time within the period, and the sleep or inactive time within the period, wherein these modes are triggered or configured on demand;

[0449] At or before the start of the active period of the working mode, the reader may send the first R2D information, and the device's behavior includes at least one of the following:

[0450] Continuously listen until the first R2D message from the reader is received;

[0451] Configure / predefined listening windows to listen during the active time of the working mode;

[0452] If the device has DOA services, and no first R2D information is received before the transmission resources of DOA data, the device directly transmits DOA services on the configured DOA transmission resources.

[0453] The device directly transmits DOA services on the configured DOA transmission resources.

[0454] Furthermore, mechanisms were designed to dynamically activate, update, or adjust the transmission parameters of DOA services in a timely manner, or to convert DOA transmissions to DO-DTT transmissions. This improves resource utilization efficiency, makes DOA transmissions more suitable for current channel conditions or the specific characteristics of DOA service data, and reduces blind monitoring on the reader side.

[0455] To reduce device power consumption, a mechanism is designed to support discontinuous reception or transmission, and the start time, duration, end time, and period of discontinuous reception or transmission can be adjusted.
