Description

Information indication methods, devices, network elements and A-IoT devices

[0001] This disclosure claims priority to Chinese Patent Application No. 202510123719.2, filed on January 26, 2025, entitled "Information Indication Method, Apparatus, Network Element and A-IoT Device", 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 an information indication method, apparatus, network element, and A-IoT device. Background Technology

[0003] To support the interconnection of hundreds of billions of things and address the high network construction costs and operational costs associated with large-scale deployments of IoT devices, such as battery replacements, a new type of IoT device is designed: Ambient IoT (A-IoT) devices. A-IoT devices have little or no energy storage capacity, and are characterized by low complexity, low cost, and low power consumption, which will contribute to the realization of ubiquitous sensing and interconnection.

[0004] In A-IoT communication, base stations or terminals, acting as readers, send A-IoT downlink channels (such as the Physical Reader to Device Channel, PRDCH) to A-IoT devices, instructing different types of A-IoT devices to receive the PRDCH and instructing the devices to send A-IoT uplink channels (such as the Physical Device to Reader Channel, PRDCH) to complete the backscattering of the incident signal or to autonomously send uplink response signals. To combat Sampling Frequency Offset (SFO) and multipath interference, and to improve the decoding success rate of the PRDCH or PDRCH, the PRDCH or PDRCH may contain a midamble. The midamble is distributed within the transmitted data bit blocks of the PRDCH or PDRCH, helping the reader perform time-frequency tracking, channel estimation, and interference estimation when receiving the PDRCH or the A-IoT device receiving the PRDCH, thereby improving the decoding success rate of the PDRCH or PRDCH.

[0275] In summary, in this embodiment of the present disclosure, the A-IoT device determines the mid-channel configuration information based on predefined information, pre-configured information, or the indication of first information. The first information includes: bits, payload, or information carried by the first channel; the format or type of the first channel; and at least one of the first transmission parameters. Using this method, the first network element can indicate the configuration parameter information of the R2D or D2R mid-channel to the A-IoT device, thereby enabling the A-IoT device to receive PRDCH or send PDRCH according to the mid-channel configuration information indicated by the first network element. This solves the problem of indicating the mid-channel configuration information and enables A-IoT communication between the first network element and the A-IoT device.

[0276] To more clearly describe the information indication method provided in the embodiments of this disclosure, several examples are given below.

[0277] Example 1

[0278] In A-IoT communication, the reader configures the mid-channel and instructs the A-IoT device on the mid-channel configuration information. Before receiving a PRDCH from the reader or sending a PDRCH to the reader, the A-IoT device first needs to know the mid-channel configuration information, including whether a mid-channel has been configured and its specific configuration parameters.

[0279] In the example, assume the PDRCH sent by the reader configuration device includes a mid-band (or mid-band signal). As shown in Figure 3, the duration of the mid-band is one time slot, and the period of the mid-band is three time slots. The "transmission start time of the first mid-band" in the PDRCH refers to the end time of the PDRCH control information (i.e., D2R control information) transmission. To indicate the end time of the D2R control information or the transmission start time of the first mid-band to the A-IoT device, the reader needs to indicate the offset of the "transmission start time of the first mid-band" relative to the "first reference time". The first reference point may be Alt-1: the start time of the preamble transmission, or Alt-2: the start time of the first channel transmission. Alternatively, if the length of the D2R preamble and the length of the D2R control information are pre-configured or fixed, then the offset of the "transmission start time of the first mid-band" relative to the "first reference time" does not need to be configured or indicated.

[0280] This example allows the reader to configure or indicate intermediate homing (AM) configuration information to the device using pre-configuration or signaling indication. This enables the device to obtain the AM signal configuration information and send a PDRCH accordingly. The AM signal is configured after the D2R control information, which can assist in channel estimation and interference estimation of the control information, improving the decoding success rate.

[0281] Example 2

[0282] In A-IoT communication, the reader configures the mid-channel and instructs the A-IoT device on the mid-channel configuration information. Before receiving a PRDCH from the reader or sending a PDRCH to the reader, the A-IoT device first needs to know the mid-channel configuration information, including whether a mid-channel has been configured and its specific configuration parameters.

[0283] In this example, it is assumed that the PDRCH sent by the reader configuration device includes a mid-band. As shown in Figure 4, the duration of the mid-band is one time slot, and the period of the mid-band is three time slots. The "transmission start time of the first mid-band" in the PDRCH is calculated by the device based on the first reference time and the offset of the "transmission start time of the first mid-band" relative to the "first reference time". To indicate the transmission start time of the first mid-band to the device, the reader needs to indicate to the device the "first reference time" used by the device to determine the "transmission start time of the first mid-band", and the offset of the "transmission start time of the first mid-band" relative to the "first reference time". The first reference time may be Alt-1: the start time of the preamble transmission, or Alt-2: the start time of the first channel transmission, or Alt-3: the start time of the first channel data transmission. In this way, the device only needs to add the offset of the "transmission start time of the first mid-band" relative to the "first reference time" to the time point indicated by the first reference time to obtain the transmission start time of the first mid-band.

[0284] This example allows the reader to configure or indicate intermediate homing (AM) configuration information to the device using pre-configuration or signaling instructions. This enables the device to obtain the AM signal configuration information and send a PDRCH accordingly. The AM is configured after the D2R data and its transmission can be flexibly controlled via offset, aiding in channel estimation and interference estimation, thus improving the decoding success rate. Furthermore, D2R control information can be repeated or processed using FEC (Flexible Encoding and Control) to further enhance decoding success.

[0285] Example 3

[0286] In A-IoT communication, the reader configures the mid-channel and instructs the A-IoT device on the mid-channel configuration information. Before receiving a PRDCH from the reader or sending a PDRCH to the reader, the A-IoT device first needs to know the mid-channel configuration information, including whether a mid-channel has been configured and its specific configuration parameters.

[0287] In this example, it is assumed that the PDRCH sent by the reader configuration device includes a mid-guide signal. As shown in Figure 5, the duration of the mid-guide is one time slot, and the period value of the mid-guide is three time slots. The "transmission start time of the first mid-guide" in the PDRCH is calculated by the device based on the mid-guide period value and the mid-guide duration. To indicate the transmission start time of the first mid-guide to the device, the reader needs to indicate the "first reference time" used by the device to determine the "transmission start time of the first mid-guide". The first reference time is Alt-2: the start time of the first channel transmission. Thus, the device only needs to subtract the duration of the mid-guide from the mid-guide period value to obtain the duration of the D2R information segment between the two mid-guide signals shown in Figure 5. As shown in Figure 5, the device only needs to add the duration of this D2R information segment to the time point indicated by the first reference time to obtain the transmission start time of the first mid-guide.

[0288] This example allows the reader to configure or indicate the intermediate guide configuration information to the device using pre-configuration or signaling instructions. This enables the device to obtain the configuration information of the intermediate guide signal and send a PDRCH accordingly. Since the intermediate guide is configured after a preset length of D2R information, only the period value and duration of the intermediate guide need to be configured or indicated; the offset does not need to be notified, which helps reduce design complexity.

[0289] Example 4

[0290] In A-IoT communication, the reader configures the mid-channel and instructs the A-IoT device on the mid-channel configuration information. Before receiving a PRDCH from the reader or sending a PDRCH to the reader, the A-IoT device first needs to know the mid-channel configuration information, including whether a mid-channel has been configured and its specific configuration parameters.

[0291] If the intermediate guidance configuration is directly indicated, each parameter in the intermediate guidance configuration information requires a separate signaling message or a separate field for indication. The device also needs to receive multiple signaling messages or multiple fields and decode multiple signaling messages or multiple fields to obtain all the intermediate guidance configuration parameters. This will result in a large signaling overhead and high power consumption for the device to decode the signaling messages.

[0292] If the intermediate channel configuration is indirectly indicated, as shown in Table 1, two bits can be used to represent the intermediate channel configuration index number. Each configuration index number corresponds to a set of intermediate channel configuration parameters, namely, the period value and duration of the intermediate channel as shown in the table. For example, when the intermediate channel configuration index number is 0, it means that the period value of the intermediate channel is 3 time slots and the duration of the intermediate channel is 1 time slot. In this way, the device only needs to receive and decode a signaling message or a field containing the intermediate channel configuration index number. Then, the device can obtain all the intermediate channel configuration parameter information by looking up a table (a parameter mapping table pre-stored inside the device). This reduces signaling overhead and device decoding power consumption.

[0293] Table 1, Mid-Range Configuration Index Number

[0294] This example allows the reader to configure or indicate intermediate homing configuration information to the device using pre-configuration or signaling indication, enabling the device to obtain the configuration information of the intermediate homing signal and send PDRCH based on that configuration information. Using intermediate homing configuration index numbers can effectively reduce signaling overhead and device decoding power consumption.

[0295] Example 5

[0296] In A-IoT communication, the reader configures the mid-channel and instructs the A-IoT device on the mid-channel configuration information. Before receiving a PRDCH from the reader or sending a PDRCH to the reader, the A-IoT device first needs to know the mid-channel configuration information, including whether a mid-channel has been configured and its specific configuration parameters.

[0297] Specifically, the mid-level configuration information includes the mid-level pattern, start time, reference point, offset, duration, period value, or mid-level configuration index number. To indicate the mid-level configuration information to the device, the reader can do so via the PRDCH. Depending on the stage of random access for the A-IoT device, the reader can use information bits from the paging message or the Msg2 message to indicate the mid-level configuration information. Depending on the scenario and purpose, and considering signaling overhead and device decoding complexity, the mid-level configuration information may be carried solely by the paging message, solely by the Msg2 message, or jointly by both. Additionally, the mid-level configuration information may be indicated via Layer 1 control information of the PRDCH or via higher-layer control information.

[0298] This example allows the reader to use explicit signaling to configure or indicate center-matrix configuration information to the device, enabling the device to obtain the center-matrix signal configuration information and send a PDRCH accordingly. Although explicit signaling incurs some signaling overhead, it provides more signaling, resulting in higher indication capacity and flexibility.

[0299] Example 6

[0300] In A-IoT communication, the reader configures the mid-channel and instructs the A-IoT device on the mid-channel configuration information. Before receiving a PRDCH from the reader or sending a PDRCH to the reader, the A-IoT device first needs to know the mid-channel configuration information, including whether a mid-channel has been configured and its specific configuration parameters.

[0301] Specifically, the intermediate navigator configuration information can implicitly indicate whether an intermediate navigator is configured by using at least one of the following methods: the format of the first channel (i.e., the format of PRDCH or PDRCH), the type of the first channel, the transport block size (TBS), and the transmission time interval (TTI). Similarly, the intermediate navigator pattern, start time, reference point, offset, duration, period value, or intermediate navigator configuration index number can also be implicitly indicated using the methods described above.

[0302] This example allows the reader to use implicit indication to configure or indicate center-matrix configuration information to the device, enabling the device to obtain the center-matrix signal configuration information and send a PDRCH accordingly. Implicit indication does not introduce additional signaling overhead; it is implicitly associated with other signaling, but the amount of information that can be indicated is limited.

[0303] Example 7

[0304] In A-IoT communication, the reader configures the mid-channel and instructs the A-IoT device on the mid-channel configuration information. Before receiving a PRDCH from the reader or sending a PDRCH to the reader, the A-IoT device first needs to know the mid-channel configuration information, including whether a mid-channel has been configured and its specific configuration parameters.

[0305] In this example, the mid-guide signal configuration information can be indicated to the device using both implicit and explicit methods, including:

[0306] The first configuration information is indicated by at least one of the following: the first transmission parameter, the format of the first channel, and the type of the first channel;

[0307] The second configuration information is indicated by the bits, payload, or information carried by the first channel.

[0308] Specifically, if implicit methods are used to indicate intermediate-range configuration information, the amount of information indicated will be relatively small due to limitations in the indication mechanism. Therefore, it is necessary to use explicit methods in conjunction with implicit methods to indicate intermediate-range configuration information. This way, more intermediate-range configuration information can be indicated while reducing the signaling overhead associated with indicating intermediate-range configuration information.

[0309] This example allows the reader to use both explicit and implicit indications to configure or indicate intermediate-range configuration information to the device, enabling the device to obtain the configuration information of the intermediate-range signal and send a PDRCH accordingly. The combined explicit and implicit indications can complete the indication of intermediate-range configuration information with less signaling overhead.

[0310] In summary, in this embodiment of the present disclosure, the first network element indicates the intermediate guide configuration information of R2D and / or D2R to the device through at least one of the following methods: bits, payload or information carried by the first channel, the format of the first channel, the type of the first channel, the transport block size (TBS), and the transmission time interval (TTI). The first channel refers to PRDCH or PDRCH. Using this method, the reader can indicate the configuration parameter information of the R2D or D2R intermediate guide to the device, thereby enabling the device to receive PRDCH or send PDRCH according to the intermediate guide configuration information indicated by the reader. This solves the problem of indicating the intermediate guide signal configuration parameters, enabling A-IoT communication between the A-IoT reader and the device.
