This application embodiment does not limit this.

To facilitate a better understanding of the embodiments of this application, the types of A-IoT devices are described.

A-IoT devices can be characterized based on their energy storage capacity and their ability to generate and transmit radio frequency signals. A-IoT devices include the following types:

1) Device A: No energy storage, no independent signal generation/amplification, i.e., backscatter transmission.

2) Device B: It has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy can include amplification of the reflected signal.

3) Device C: It has energy storage and independent signal generation, i.e., an active radio frequency component for transmission.

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.

To facilitate a better understanding of the embodiments of this application, the data/service types of A-IoT are explained.

Device initiation (A-IoT device-originated, DO) and device termination (A-IoT device-terminated, DT) are two distinct events. DO and DT data indicate that the data stream originates from or is transmitted to an A-IoT device (similar to an RFID tag). For data streams originating from A-IoT devices (DO data), further classification is possible: automatic device initiation (A-IoT device-originated-autonomous, DO-A) and device initiation-terminated triggering (A-IoT device-originated–A-IoT device-terminated-triggered, DO-DTT).

DO-A stands for Device Autonomous Data Transmission, which involves connecting a large number of various sensors that collect and proactively report information about the environment, the device, and the organisms when necessary.

DO-DTT means that data transmission is initiated by the device via the network. 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 IoT device, this service should be considered as a DO service initiated by the tag, triggered by a command sent by the reader.

To facilitate a better understanding of the embodiments of this application, the topology of A-IoT is explained.

As shown in Figure 2, the base station (BS) can communicate directly with A-IoT devices;

As shown in Figure 3, the base station (BS) can communicate with A-IoT devices through intermediate nodes.

It is not expected that a certain portion of the second transmission will occur earlier than the first time interval;

A response is not expected earlier than the first time interval;

A specific portion of the second transmission that is not expected to be scheduled or indicated occurs before the end of the first time interval;

If at least a portion of the second transmission occurs earlier than the first time interval, discard the control information corresponding to the second transmission, or discard part or all of the first transmission associated with the second transmission.

If at least part of the scheduled or indicated second transmission occurs before the end of the first time interval, discard the control information corresponding to the second transmission, or discard part or all of the first transmission associated with the second transmission.

If at least a portion of the second transmission occurs earlier than the first time interval, discard part or all of the second transmission.

In this embodiment of the application, "before the end of the first time interval" can also be replaced with: "before the end of the first time interval", "before the start of the first time interval", or "before the first time interval".

Specifically, if at least a portion of the second transmission occurs earlier than the first time interval, part or all of the first transmission associated with the second transmission is discarded. For example, the first transmission associated with the second transmission may carry data from the first transmission and control information corresponding to the second transmission. The control information indicates the resource location of the second transmission. The second type of device first reads the control information corresponding to the second transmission. If it finds that at least a portion of the second transmission indicated by the control information is earlier than the first time interval, it discards the remaining data portion of the first transmission. For example, after decoding the control information carried in the first transmission, if the second type of device finds that the resource of the second transmission indicated by the control information is earlier than a certain reference point plus the first time interval, it will not continue decoding the subsequent portion of the first transmission (i.e., it considers that the first transmission or the control information carried by the first transmission is not actually for the second type of device, or that the first transmission or the control information carried by the first transmission is not suitable for the second type of device; for example, the first transmission or the control information carried by the first transmission is multicast or broadcast, but the second transmission it indicates/schedules can only be responded to by some second type of devices).

Specifically, if at least a portion of the second transmission occurs before the first time interval, part or all of the second transmission is discarded. For example, if at least a portion of the second transmission occurs before the first time interval, the portion of the second transmission preceding the first time interval is discarded (the remaining portion continues to be transmitted), or the portion of the second transmission following the start of the first time interval is discarded, or all of the second transmission is discarded.

Specifically, if at least a portion of the second transmission occurs before the end of the first time interval, or if at least a portion of the second transmission occurs within the first time interval, the second transmission is sent after the first time interval, or postponed until after the first time interval. This embodiment is suitable for situations where the first time interval is actually longer than the processing limit of the second type of device, in which case its effect is equivalent to a scheduling limit.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a first time interval as _{T_R2D_min} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is an A-IoT device, the first operation includes at least one of the following; or if the second device is an A-IoT device, the second operation includes at least one of the following:

(For example, A-IoT devices) do not respond to R2D transmissions or send D2R transmissions before _{T_R2D_min} (e.g., the end) / before the first reference time point + _{T_R2D_min} ;

(For example, A-IoT devices) do not expect (e.g., scheduled/instructed) D2R transmissions to occur earlier than _{T_R2D_min} (the end time) / the first reference time point + _{T_R2D_min} ;

If at least part of the (e.g., scheduled/instructed) D2R transmission occurs earlier than _{T_R2D_min} (the end time) / first reference time point + _{T_R2D_min} , (e.g., the A-IoT device) discards/abandons/cancels/skips the control information carried in the R2D / at least part/remaining part of the R2D transmission; for example, if the A-IoT device finds that the instructed D2R transmission resource is earlier than the first reference time point + time interval after decoding the control information carried in the R2D, it will not continue decoding (i.e., it considers that the R2D or the control information carried in the R2D is not actually for itself, or is not suitable for itself; for example, the R2D/the control information carried in the R2D is multicast or broadcast, but only some A-IoT devices can respond to its instructed/scheduled D2R).

(For example, if at least a portion of a scheduled/instructed D2R transmission is within _{T_R2D_min} /before the end of _{T_R2D_min} /before the first reference time point + _{T_R2D_min} ), (e.g., an A-IoT device) discards/abandons/cancels/skips at least a portion of the D2R transmission; for example, (e.g., an A-IoT device) discards/abandons/cancels/skips the D2R transmission; and for example, (e.g., an A-IoT device) discards/abandons/cancels/skips the portion of the D2R transmission located within _{T_R2D_min} /before the end of _{T_R2D_min} /before the first reference time point + _{T_R2D_min} , (e.g., and/or, the remaining portion may be transmitted);

(For example, if at least part of a scheduled/indicated D2R transmission is within _{T_R2D_min} /before the end of _{T_R2D_min} /before the first reference time point + _{T_R2D_min} ), the (A-IoT device) waits until _{T_R2D_min} (end time)/reference point + _{T_R2D_min} before sending the D2R transmission; for example, the (A-IoT device) delays sending until the first reference time point + _{T_R2D_min} (this clause is suitable when _{T_R2D_min} is actually greater than the A-IoT device's processing limit, in which case it acts as a scheduling limit).

In some embodiments, the first time information includes the first time interval; when the first device is a first type of device, the first operation includes at least one of the following; and/or, when the second device is a first type of device, the second operation includes at least one of the following:

The second transmission is not received or responded to before the end of the first time interval;

It is not expected that a certain portion of the second transmission will occur earlier than the first time interval;

A specific portion of the second transmission that is not expected to be scheduled or indicated occurs before the end of the first time interval;

Discard part or all of the reception of the second transmission;

If at least part of the scheduled or indicated second transmission occurs before the end of the first time interval, or if at least part of the scheduled or indicated second transmission occurs within the first time interval, part or all of the reception of the second transmission is discarded.

The second transmission is received after the first time interval;

If at least a portion of the scheduled or indicated second transmission occurs before the end of the first time interval, or if at least a portion of the scheduled or indicated second transmission occurs within the first time interval, the second transmission shall be received after the first time interval.

Specifically, it is not expected that a particular portion of the second transmission will occur earlier than the first time interval, or that a particular portion of the second transmission that is scheduled or indicated will occur earlier than the end of the first time interval. This is suitable for situations where the resources or length of the second transmission are not entirely controlled by the first type of device, such as in the case of Automatic Device Initiation (DO-A).

Specifically, if at least a portion of the scheduled or indicated second transmission occurs before the end of the first time interval, or if at least a portion of the scheduled or indicated second transmission occurs within the first time interval, part or all of the reception of the second transmission is discarded. For example, if at least a portion of the scheduled or indicated second transmission occurs before the end of the first time interval, the reception of the portion of the second transmission occurring before the first time interval is discarded (the remaining portion continues to be received), or the reception of the portion of the second transmission occurring after the start of the first time interval is discarded, or all of the reception of the second transmission is discarded. For example, if at least a portion of the scheduled or indicated second transmission occurs within the first time interval, the reception of the portion of the second transmission occurring within the first time interval is discarded (the remaining portion continues to be received), or the reception of the portion of the second transmission occurring after the first time interval is discarded, or all of the reception of the second transmission is discarded.

In some embodiments, the starting point of the first time interval is a first reference time point;

The first reference time point is determined based on at least one of the following: the time information of the first transmission, the time information of the control information corresponding to the second transmission, and the first time offset (delta 1).

Optionally, the time information of the first transmission includes at least one of the following: the end time of the first transmission, the start time of the first transmission, and the transmission time of the first transmission from the start time to the end time.

Optionally, the time information of the control information corresponding to the second transmission includes at least one of the following: the end time point of the control information corresponding to the second transmission, the start time point of the control information corresponding to the second transmission, and the transmission time of the control information corresponding to the second transmission from the start time point to the end time point.

Optionally, the first time offset is agreed upon by the protocol, or the first time offset is determined by the first device, or the first time offset is configured by the second device.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a first time interval as _{T_R2D_min} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is a reader, the first operation includes at least one of the following; or if the second device is a reader, the second operation includes at least one of the following:

(For example, a reader) does not receive D2R transmissions before _{T_R2D_min} (end) / before the first reference time point + _{T_R2D_min} ;

(For example, the reader) does not expect (e.g., scheduled/instructed) D2R transmissions to occur earlier than _{T_R2D_min} (the end time) / the first reference time point + _{T_R2D_min} ; this clause is suitable for situations where the D2R transmission resources or length are not entirely controlled by the reader, such as DO-A;

(For example, if at least a portion of a scheduled/indicated D2R transmission is within _{T_R2D_min} /earlier than the end of _{T_R2D_min} /before the reference point + _{T_R2D_min} ), (e.g., the reader) discards/abandons/cancels/skips at least a portion of the D2R transmission reception; for example, (e.g., the reader) discards/abandons/cancels/skips the reception of a D2R transmission; and for example, (e.g., the reader) discards/abandons/cancels/skips the reception of the portion of the D2R transmission located within _{T_R2D_min} /earlier than the end of _{T_R2D_min} /before the first reference time point + _{T_R2D_min} , (e.g., and/or, the remaining portion may be received);

(For example, if at least part of the scheduled/indicated D2R transmission is within _{T_R2D_min} / before the end time of _{T_R2D_min} / before the reference point + _{T_R2D_min} ), (e.g., the reader) waits until _{T_R2D_min} (end time) / the first reference time point + _{T_R2D_min} before receiving the D2R transmission; adapting to the delayed behavior of A-IoT devices.

Maximum/longest response time/interval (in one implementation, it can be the maximum/longest response time/interval from the perspective of the second type of device (such as A-IoT device), i.e. the maximum/longest response time/interval of the second type of device);

Maximum/Longest Receive Wait/Receive Prepare Time (in one implementation, the maximum/longest receive wait/receive prepare time from the perspective of a first-class device (e.g., a reader), i.e., the maximum/longest receive wait/receive prepare time of the first-class device);

(e.g., the maximum/longest receive interval before preparing to receive D2R) (in one implementation, this could be the maximum/longest receive interval from the perspective of a first-class device (e.g., a reader).

In some embodiments, the first time information includes the second time interval; when the first device is a second type of device, the first operation includes, but is not limited to, at least one of the following; and/or, when the second device is a second type of device, the second operation includes, but is not limited to, at least one of the following:

The second transmission is sent no later than the second time interval, or the second transmission is completed no later than the second time interval, or the transmission of the second transmission ends or stops no later than the second time interval, or the transmission of the second transmission begins no later than the second time interval.

The second transmission is sent no later than the end of the second time interval, or the second transmission is completed no later than the end of the second time interval, or the transmission of the second transmission is ended or stopped no later than the end of the second time interval, or the transmission of the second transmission is started no later than the end of the second time interval.

No response is given to the first transmission after the second time interval;

The second transmission is not sent after the second time interval, or the transmission of the second transmission is terminated or stopped after the second time interval;

It is not expected that any part of the second transmission will be later than the second time interval;

A specific portion of the second transmission that is not expected to be scheduled or indicated is later than the end of the second time interval;

If the processing time or time interval from the end of the first transmission to the start of the second transmission is greater than or equal to the second time interval, or if the sum of the processing time of the first transmission and the preparation time of the second transmission is greater than or equal to the second time interval, discard part or all of the second transmission, and/or send a negative acknowledgment or failure message, and/or send a delay message, and/or send time offset information, and/or send expected or supported time information, and/or determine whether to continue sending the second transmission, and/or determine the sending method of the second transmission;

If the processing time or time interval from the end point of the first transmission to the start point of the second transmission is greater than or equal to the second time interval, or if the sum of the processing time of the first transmission and the preparation time of the second transmission is greater than or equal to the second time interval, and the control information corresponding to the first transmission includes a command for the first session or the first transmission includes a command for the first session, the state of the first session remains unchanged, or the first session is maintained, or the state of the second type of device is not modified, or the session is suspended or paused.

Discard part or all of the second transmission;

If at least part of the scheduled or indicated second transmission is later than the end of the second time interval, or if at least part of the scheduled or indicated second transmission is outside the second time interval, part or all of the second transmission is discarded.

The second transmission is sent during the second time interval or before the end of the second time interval;

If at least a portion of the scheduled or indicated second transmission is later than the end of the second time interval, or if at least a portion of the scheduled or indicated second transmission is outside the second time interval, the second transmission shall be sent within the second time interval or before the end of the second time interval.

Specifically, the second transmission may be sent no later than the second time interval, or the second transmission may be completed no later than the second time interval, or the transmission of the second transmission may end or stop no later than the second time interval, or the transmission of the second transmission may begin no later than the second time interval; alternatively, the second transmission may be sent no later than the end of the second time interval, or the second transmission may be completed no later than the end of the second time interval, or the transmission of the second transmission may end or stop no later than the end of the second time interval, or the transmission of the second transmission may begin no later than the end of the second time interval. Optionally, all second-class devices satisfy this embodiment, or a specific second-class device satisfies this embodiment. For example, a specific second-class device may be a second-class device that matches the identifier (ID) indicated by the first transmission or the control information carried by the first transmission. Another example is that a specific second-class device may be a second-class device of a specific type. Yet another example is that a specific second-class device may be a second-class device participating in a specific session or process. Further optionally, if at least one or at least N second-class devices fail to meet the requirements, it is considered a failure, or the second-class device fails to meet the timing requirements defined by the standard, or the related second transmission fails or the first transmission fails, or the related control command fails/ends, or the second-class device is inaccessible or untouchable.

Specifically, if the processing time or time interval from the end of the first transmission to the start of the second transmission is greater than or equal to the second time interval, or if the sum of the processing time of the first transmission and the preparation time of the second transmission is greater than or equal to the second time interval, part or all of the second transmission is discarded, and/or a negative acknowledgment (e.g., error, NACK, or higher layer NACK) or a failure message is sent, and/or a postponement message is sent, and/or time offset information is sent, and/or expected or supported time information is sent, and/or it is determined whether to continue sending the second transmission, and/or the transmission method of the second transmission is determined. This embodiment is applicable to situations where the second type of device cannot process the second transmission in time. For example, the second type of device cannot complete the second transmission, so it sends a postponement message to postpone the subsequent first or second transmission. Another example is that the time offset information is the difference between the time expected or supported by the second type of device and the second time interval. Another example is that the expected or supported time information sent is the time expected or supported by the first type of device. Yet another example is that the second type of device determines whether to continue sending the second transmission based on its implementation, and/or the second type of device determines the transmission method of the second transmission based on its implementation. For example, a second type of device can decide whether and/or how to continue the transmission of the second transmission based on its own processing time capabilities.

Specifically, if the processing time or time interval from the end point of the first transmission to the start point of the second transmission is greater than or equal to the second time interval, or if the sum of the processing time of the first transmission and the preparation time of the second transmission is greater than or equal to the second time interval, and the control information corresponding to the first transmission includes a command for the first session or the first transmission includes a command for the first session, the state of the first session remains unchanged, or the first session is maintained, or the state of the second type of device is not modified, or it is suspended or paused. For example, if the second type of device receives another command for the first session (e.g., an inventory command), the second type of device can continue to participate in the inventory of the first session.

Specifically, if at least a portion of the scheduled or indicated second transmission is later than the end of the second time interval, or if at least a portion of the scheduled or indicated second transmission is outside the second time interval, part or all of the second transmission is discarded, and/or the remaining portion of the second transmission after being discarded is transmitted. This embodiment corresponds to the situation where the second type of device has time to process the second transmission, but the resources of the second transmission are outside the second time interval.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a second time interval as _{T_R2D_max} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is an A-IoT device, the first operation includes at least one of the following; or if the second device is an A-IoT device, the second operation includes at least one of the following:

(For example, A-IoT devices) transmit D2R/complete D2R/end D2R transmission/start D2R transmission no later than _{T_R2D_max} (end time)/second reference time point + _{T_R2D_max} ; further optionally, all A-IoT devices meet this requirement, or a specific A-IoT device meets this requirement, wherein the specific A-IoT device may be an A-IoT device that matches the ID (e.g., indicated by R2D transmission/control information), or the specific A-IoT device may be a specific type of A-IoT device, or the specific A-IoT device may be an A-IoT device participating in a specific session or process; further optionally, if at least one or at least N A-IoT devices do not meet the requirement, the test is considered to have failed, or the A-IoT device has failed to meet the timing requirements defined by the standard, or the related D2R or R2D transmission has failed, or the related control command has failed/ended, or the A-IoT device is inaccessible or untouchable;

(For example, A-IoT devices) will no longer respond to R2D transmissions or send D2R transmissions after _{T_R2D_max} (e.g., the end) / after the second reference time point + _{T_R2D_max} ;

(For example, A-IoT devices) do not expect (e.g., scheduled/instructed) D2R transmissions to be later than _{T_R2D_max} (the end time) / the second reference time point + _{T_R2D_max} ;

(For example, assuming the A-IoT device transmits D2R no later than _{T_R2D_max} / second reference time point + _{T_R2D_max} ) If the processing time of the A-IoT device (e.g., the processing time from the “end” of R2D transmission to the “start” of D2R transmission, or the total time required for the A-IoT device to process R2D and prepare D2R) is greater than _{T_R2D_max} (this corresponds to the case where the A-IoT device cannot process in time), then the behavior of the A-IoT device includes at least one of the following:

Drop/abandon/cancel/skip at least part/remaining part of the corresponding D2R transmission (Drop D2R); for example, (e.g., A-IoT device) drop/abandon/cancel/skip the entire D2R transmission; for example, (e.g., A-IoT device) drop/abandon/cancel/skip the part of the D2R transmission that is within _{T_R2D_max} /before the end time of _{T_R2D_max} /before the second reference time point + _{T_R2D_max} (e.g., and/or, the remaining part can be transmitted);

The system will respond with a negative response (such as error, NACK, or higher layer NACK) or send a failure message.

Feedback delay messages, for example, when an A-IoT device is unable to complete D2R, it sends a delay message hoping to postpone the next R2D or D2R;

The feedback offset message is the difference between the time that the A-IoT device expects or can support and _{T_R2D_max} .

Feedback time message/requirement, wherein the time message/requirement is the time that the A-IoT device expects or can support;

If the transmission of control information/R2D is a command (e.g., an inventory command) for a specific session (e.g., session 1), the A-IoT device maintains its state for that session, or the A-IoT device maintains the session, or the A-IoT device does not modify its own state, or the A-IoT device suspends/pauses. Furthermore, if the A-IoT device receives another command for that session (e.g., an inventory command), the A-IoT device can continue to participate in the inventory of that session.

It depends on the implementation of the A-IoT device. For example, the A-IoT device can decide whether and/or how to continue the D2R transmission based on its own processing time capability.

(For example, if at least a portion of a scheduled/instructed D2R transmission is outside _{T_R2D_max} /later than the end time of _{T_R2D_max} /after the second reference time point + _{T_R2D_max} ), (e.g., an A-IoT device) discards/abandons/cancels/skips at least a portion of the corresponding D2R transmission (this clause corresponds to the case where the A-IoT device has time to process it, but the resources are outside the interval); for example, (e.g., an A-IoT device) discards/abandons/cancels/skips all D2R transmissions; for example, (e.g., an A-IoT device) discards/abandons/cancels/skips the portion of the D2R transmission located outside _{T_R2D_max} /later than the end time of _{T_R2D_max} /after the second reference time point + _{T_R2D_max} , (e.g., and/or, the remaining portion can be transmitted);

(For example, if at least part of a scheduled/instructed D2R transmission is outside _{T_R2D_max} /later than the end of _{T_R2D_max} /after the second reference time point + _{T_R2D_max} ), (e.g., an A-IoT device) sends a D2R transmission earlier than _{T_R2D_max} .

In some embodiments, the first time information includes the second time interval; when the first device is a device of the first type, the first operation includes, but is not limited to, at least one of the following; and/or, when the second device is a device of the first type, the second operation includes, but is not limited to, at least one of the following:

Receive or detect the second transmission;

The second transmission is received or detected before the end of the second time interval;

Receive or detect the second transmission during the second time interval;

Stop receiving or stop detecting the second transmission;

Outside of or after the second time interval, the second transmission is no longer received or detected, or reception or detection of the second transmission is stopped.

If the second transmission is not received or only a portion of the second transmission is received, the second transmission is determined to have failed.

If the second transmission is not received or only a portion of the second transmission is received before the end of the second time interval or during the second time interval, the second transmission is determined to have failed.

It is not expected that any part of the second transmission will be later than the second time interval;

A specific portion of the second transmission that is not expected to be scheduled or indicated is later than the end of the second time interval;

Discard part or all of the reception of the second transmission;

If at least part of the scheduled or indicated second transmission is later than the end of the second time interval, or if at least part of the scheduled or indicated second transmission is outside the second time interval, part or all of the reception of the second transmission is discarded.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a second time interval as _{T_R2D_max} , the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is a reader, the first operation includes at least one of the following; or if the second device is a reader, the second operation includes at least one of the following:

(For example, before _{T_R2D_max} (end) / within _{T_R2D_max} / before the second reference time point + _{T_R2D_max} ) The Reader receives/detects D2R transmissions;

(For example, outside of _{T_R2D_max} / after _{T_R2D_max} / after the second reference time point + _{T_R2D_max} ) The Reader no longer receives / no longer detects D2R transmissions, or stops receiving / stops detecting D2R transmissions;

(For example, before _{T_R2D_max} (end) / within _{T_R2D_max} / no earlier than the second reference time point + _{T_R2D_max} ), if the Reader does not receive a D2R transmission from the device or only receives a partial D2R transmission, it considers the R2D transmission to have failed.

(For example, a Reader) does not expect (e.g., scheduled/instructed) D2R transmissions to be later than _{T_R2D_max} (the end time) / the second reference time point + _{T_R2D_max} ;

If (e.g., instructed/informed) at least a portion of the D2R transmission resource is later than _{T_R2D_max} (the end time)/is outside of _{T_R2D_max} /is at the second reference time point + _{T_R2D_max} , (e.g., the reader) discards/abandons/cancels/skips at least a portion of the D2R transmission reception; for example, (e.g., the reader) discards/abandons/cancels/skips the reception of the D2R transmission; or, for example, (e.g., the reader) discards/abandons/cancels/skips the reception of the portion of the D2R transmission that is outside of _{T_R2D_max} /is earlier than the end time of _{T_R2D_max} /is after the second reference time point + _{T_R2D_min} (e.g., and/or, the remaining portion may be received).

In some embodiments, the starting point of the second time interval is a second reference time point;

The second reference time point is determined based on at least one of the following: the time information of the first transmission, the time information of the control information corresponding to the second transmission, and the second time offset (delta 2).

Optionally, the time information of the first transmission includes at least one of the following: the end time of the first transmission, the start time of the first transmission, and the transmission time of the first transmission from the start time to the end time.

Optionally, the time information of the control information corresponding to the second transmission includes at least one of the following: the end time point of the control information corresponding to the second transmission, the start time point of the control information corresponding to the second transmission, and the transmission time of the control information corresponding to the second transmission from the start time point to the end time point.

Optionally, the second time offset is agreed upon by the protocol, or the second time offset is determined by the first device, or the second time offset is configured by the second device.

For example, as shown in Figure 6, the first transmission is R2D, the second transmission is D2R, the first time interval can be _{T_D2R_min} , and the second time interval can be _{T_D2R_max} . For example, _{T_D2R_min} can be the minimum time interval from D2R to R2D, and _{T_D2R_max} can be the maximum time interval from D2R to R2D.

Specifically, the time interval for sending the first transmission is not required for the second transmission, and the description is based on the first type of device as the execution subject.

Optionally, a time interval for responding to the second transmission is not required, including:

Specifically, _{T_D2R_min} includes, but is not limited to, at least one of the following:

The minimum time interval from the end of the D2R transmission to the start of the R2D transmission;

The minimum time interval from the start or end of receiving a D2R transmission to the start of an R2D transmission;

No minimum response time interval is required (e.g., the reader sends R2D for D2R transmissions), meaning the reader is not required to send R2D before or no earlier _{than T_D2R_min ;}

Minimum/shortest response time/interval (in one implementation, this could be the minimum/shortest response time/interval from the perspective of a first-class device (e.g., a reader);

Minimum/shortest waiting (receiving)/preparation (receiving) time (in one implementation, it can be the minimum/shortest waiting (receiving)/preparation (receiving) time from the perspective of the second type of device (such as A-IoT device), i.e. the minimum/shortest waiting (receiving)/preparation (receiving) time of the second type of device).

(e.g., the minimum/shortest time interval before preparing to send D2R) (in one implementation, this could be the minimum/shortest time interval from the perspective of a first-class device (e.g., a reader)).

In some embodiments, the first time information includes the first time interval; when the first device is a first type of device, the first operation includes, but is not limited to, at least one of the following; and/or, when the second device is a first type of device, the second operation includes, but is not limited to, at least one of the following:

It is not expected that a specific portion of the first transmission will occur earlier than the first time interval;

A response is not expected earlier than the first time interval;

It is not expected that a particular portion of the first transmission will occur before the end of the first time interval;

If at least a portion of the first transmission occurs earlier than the first time interval, discard the control information corresponding to the first transmission, or discard part or all of the second transmission associated with the first transmission.

(If at least part of the R2D transmission is within _{T_D2R_min} / before the end of _{T_D2R_min} / before the third reference time point + _{T_D2R_min} ), (e.g., Reader) waits until _{T_D2R_min} (end time) / the third reference time point + _{T_D2R_min} before sending the R2D transmission; for example, (e.g., Reader) delays sending until the third reference time point + _{T_D2R_min} .

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a first time interval as _{T_D2R_min} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is an A-IoT device, the first operation includes at least one of the following; or if the second device is an A-IoT device, the second operation includes at least one of the following:

(For example, A-IoT devices) do not receive/detect R2D transmissions before _{T_D2R_min} (end) / before the third reference time point + _{T_D2R_min} ;

(For example, A-IoT devices) do not expect R2D transmission to occur earlier than _{T_D2R_min} (the end time) / third reference time point + _{T_D2R_min} ;

(For example, if at least a portion of the R2D transmission is within _{T_D2R_min} /earlier than the end of _{T_D2R_min} /before the third reference time point + _{T_D2R_min} ), (e.g., an A-IoT device) discards/abandons/cancels/skips the reception of at least a portion of the R2D transmission; for example, (e.g., an A-IoT device) discards/abandons/cancels/skips the reception of the R2D transmission; and for example, (e.g., an A-IoT device) discards/abandons/cancels/skips the reception of the portion of the R2D transmission located within _{T_D2R_min} /earlier than the end of _{T_D2R_min} /before the third reference time point + _{T_D2R_min} , (e.g., and/or, the remaining portion may be received);

(For example, if at least part of the R2D transmission is within _{T_D2R_min} / before the end of _{T_D2R_min} / before the third reference time point + _{T_D2R_min} ), (e.g., an A-IoT device) waits until _{T_D2R_min} (end time) / the third reference time point + _{T_D2R_min} before receiving the R2D transmission; this is adapted to the reader's delayed behavior.

In some embodiments, the starting point of the first time interval is a third reference time point;

The third reference time point is determined based on at least one of the following: the time information of the second transmission associated with the first transmission, the time information of the control information corresponding to the first transmission, and the third time offset (delta 3).

The maximum time interval from the end point of the second transmission to the end point of the first transmission;

The maximum time interval from the start or end of receiving the second transmission to the start point of the first transmission;

The maximum time interval from the start or end of receiving the second transmission to the end of the first transmission.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a second time interval as _{T_D2R_max} , the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, _{T_D2R_max} includes, but is not limited to, at least one of the following:

The maximum time interval from the end of D2R transmission to the start or end of R2D transmission; the end point of R2D transmission is introduced for extension, the purpose of which is for the reader to complete the R2D transmission before _{T_D2R_max} . Considering that the device does not know how long the reader will take to transmit, a device receiving deadline is suggested.

The maximum time interval from the start or end of receiving D2R transmissions to the start or end of R2D transmissions; an extension to the end point of R2D transmissions is introduced, with the aim of ensuring that the reader finishes sending R2D transmissions before _{T_D2R_max} . This is because the device does not know how long the reader will take to send, so a device receiving deadline is suggested.

The requirement (e.g., the A-IoT device performing R2D reception/detection for D2R transmission) is to wait for a maximum time interval, that is, the A-IoT device is required to receive R2D before or no later _{than T_D2R_max ;}

(e.g., the maximum/maximum time interval before preparing to send D2R) (in one implementation, this could be the maximum/maximum time interval from the perspective of a first-class device (e.g., a reader).

In some embodiments, the first time information includes the second time interval; when the first device is a device of the first type, the first operation includes, but is not limited to, at least one of the following; and/or, when the second device is a device of the first type, the second operation includes, but is not limited to, at least one of the following:

The first transmission is sent no later than the second time interval, or the first transmission is completed no later than the second time interval, or the transmission of the first transmission ends or stops no later than the second time interval, or the transmission of the first transmission begins no later than the second time interval.

The first transmission is sent no later than the end of the second time interval, or the first transmission is completed no later than the end of the second time interval, or the transmission of the first transmission is ended or stopped no later than the end of the second time interval, or the transmission of the first transmission is started no later than the end of the second time interval.

No response is given to the second transmission after the second time interval;

It is not expected that a certain portion of the first transmission will be later than the second time interval;

It is not expected that a certain portion of the first transmission will be later than the end of the second time interval;

If the time interval or processing time from the end of the second transmission to the start of the first transmission is greater than or equal to the second time interval, or if the sum of the processing time of the second transmission and the preparation time of the first transmission is greater than or equal to the second time interval, discard part or all of the first transmission, and/or send a negative acknowledgment or failure message, and/or send a delay message, and/or send time offset information, and/or send expected or supported time information, and/or determine whether to continue sending the first transmission, and/or determine the transmission method of the first transmission;

If the time interval or processing time from the end point of the second transmission to the start point of the first transmission is greater than or equal to the second time interval, or if the sum of the processing time of the second transmission and the preparation time of the first transmission is greater than or equal to the second time interval, and the control information corresponding to the second transmission includes a command for the second session or the second transmission includes a command for the second session, keep the state of the second session unchanged, or maintain the second session, or do not modify the state of the second type of device, or suspend or pause.

Discard part or all of the first transmission;

If at least a portion of the first transmission is later than the end of the second time interval, or if at least a portion of the first transmission is outside the second time interval, discard part or all of the first transmission;

The first transmission is sent during the second time interval or before the end of the second time interval;

If at least a portion of the first transmission is later than the end of the second time interval, or if at least a portion of the first transmission is outside the second time interval, the first transmission is sent within the second time interval or before the end of the second time interval.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a second time interval as _{T_D2R_max} , the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is a reader, the first operation includes at least one of the following; or if the second device is a reader, the second operation includes at least one of the following:

(e.g., Reader) performs or begins R2D transmission or ends or completes R2D transmission no later than _{T_D2R_max} (the end time) / fourth reference time point + _{T_D2R_max} ; further optionally, all readers meet this requirement, or a specific reader meets this requirement, wherein the specific reader may be a reader matching a specific ID, or the specific reader may be a reader of a specific type, or the specific reader may be a reader participating in a specific session or a specific process; further optionally, if at least one or at least N readers do not meet the requirement, the test is considered to have failed, or the reader has failed to meet the timing requirements defined by the standard, or the related D2R or R2D transmission has failed, or the related control command has failed/ended, or the reader is inaccessible or untouchable;

(e.g., Reader) will stop sending R2D transmissions/stop R2D transmissions after _{T_D2R_max} (e.g., end) / after the fourth reference time point + _{T_D2R_max} ;

(For example, Reader) does not expect the start or end of R2D to be later than the end time of _{T_D2R_max} / fourth reference time point + _{T_D2R_max} ;

If the reader's processing time (e.g., the processing time from the "end" of D2R to the "start" or "end" of R2D, or the total time required for the reader to process R2D and prepare for D2R) is greater than _{T_D2R_max} , then the reader's behavior (e.g., primarily for cases where the reader is a UE) includes at least one of the following: discarding/abandoning/cancelling/skipping at least a portion of the corresponding R2D transmission (e.g., Drop R2D); providing a negative acknowledgment (e.g., error or NACK or higher layer NACK) or sending a failure message; providing a delay message, e.g., the reader anticipates it cannot complete D2R or R2D and therefore sends a delay message to postpone the subsequent R2D; providing an offset message, the offset being the difference between the time the reader expects or can support and _{T_R2D_max} ; providing a time message/requirement, the time message/requirement being the time the reader expects or can support.

If the transmission of control information/R2D is a command (e.g., an inventory command) for a specific session (e.g., session 1), then the reader maintains its state for that session, or the reader maintains the session, or the reader does not modify its own state, or the reader suspends/pauses. Furthermore, if the terminal reader receives another command (e.g., an inventory command) for that session, then the reader can continue to participate in the inventory of that session.

It depends on the reader's implementation. For example, the reader can decide whether and/or how to continue the R2D transmission based on its own processing time capabilities.

(For example, if at least part of the R2D transmission is outside _{T_D2R_max} /later than the end time of _{T_D2R_max} /after the fourth reference time point + _{T_D2R_max} ), (e.g., the reader) discards/abandons/cancels/skips at least part of the corresponding R2D transmission (this clause corresponds to the case where the reader has time to process, but for some reason the available R2D resources are outside the interval); for example, (e.g., the reader) discards/abandons/cancels/skips the entire R2D transmission; and for another example, (e.g., the reader) discards/abandons/cancels/skips the part of the R2D transmission that is outside _{T_D2R_max} /later than the end time of _{T_D2R_max} /after the fourth reference time point + _{T_D2R_max} (e.g., and/or, the remaining part can be transmitted);

(For example, if at least part of the R2D transmission is outside _{T_D2R_max} /later than the end of _{T_D2R_max} /after the fourth reference time point + _{T_D2R_max} ), (such as the reader) sends the R2D transmission earlier within _{T_D2R_max} .

In some embodiments, the first time information includes the second time interval; when the first device is a second type of device, the first operation includes, but is not limited to, at least one of the following; and/or, when the second device is a second type of device, the second operation includes, but is not limited to, at least one of the following:

Receive or detect the first transmission during the second time interval;

Stop receiving or stop detecting the first transmission;

Outside of or after the second time interval, the first transmission is no longer received or detected, or reception or detection of the first transmission is stopped.

If the first transmission is not received, or only a portion of the first transmission is received, or at least a portion of the received transmission is not associated with the second transmission, or the received first transmission does not correspond to the second type of device, the first transmission is determined to have failed, or the first transmission is determined to have succeeded, or the status of the currently participated process (such as inventory process, access process, identification process, etc.) is not updated, or the status of the currently participated process (such as inventory process, access process, identification process, etc.) is updated, or the device does not participate in subsequent inventory or the same inventory, or enters a specific state or power-saving mode, or the status of the second type of device is not modified, or the status of the second type of device is updated;

If, before the end of the second time interval or within the second time interval, the first transmission is not received, or only a portion of the first transmission is received, or at least a portion of the received transmission is not associated with the second transmission, or the received first transmission does not correspond to the second type of device, the first transmission is determined to have failed, or the first transmission is determined to have succeeded, or the status of the currently participated process (such as inventory process, access process, identification process, etc.) is not updated, or the status of the currently participated process (such as inventory process, access process, identification process, etc.) is updated, or the device does not participate in subsequent inventory or the same inventory, or enters a specific state or power-saving mode, or the status of the second type of device is not modified, or the status of the second type of device is updated;

It is not expected that a certain portion of the first transmission will be later than the second time interval;

It is not expected that a certain portion of the first transmission will be later than the end of the second time interval;

Discard part or all of the reception of the first transmission, and/or send a negative acknowledgment or a failure message for the first transmission;

If at least a portion of the first transmission is later than the end of the second time interval, or if at least a portion of the first transmission is outside the second time interval, discard part or all of the reception of the first transmission, and/or send a negative acknowledgment or a failure message for the first transmission.

(For example, before _{T_D2R_max} (end) / within _{T_D2R_max} / before the fourth reference time point + _{T_D2R_max} ) the A-IoT device receives/detects the transmission of R2D;

(For example, outside of _{T_D2R_max} / after _{T_D2R_max} / after the fourth reference time point + _{T_D2R_max} ) A-IoT devices no longer receive / no longer detect R2D transmissions, or stop receiving / stop detecting R2D transmissions;

(For example, before _{T_D2R_max} (end) / within _{T_D2R_max} / no earlier than the fourth reference time point + _{T_D2R_max} ), if the A-IoT device does not receive R2D transmissions, or only receives partial R2D transmissions, or the received R2D transmissions do not correspond to the A-IoT device, then at least one of the following behaviors will occur:

The D2R transmission is considered to have failed; for example, if the D2R transmission is a response to a command, and no R2D transmission is received, the D2R transmission is considered to have failed.

The D2R transmission is considered successful; for example, if the process is in the process of access or inventory, or if the D2R is a response to an inventory or query, and no R2D transmission is received, the D2R transmission is considered successful.

Do not update the status of the currently participating inventory, access, or process;

(For example, A-IoT devices) do not expect R2D transmission to be later than _{T_D2R_max} (the end time) / outside _{T_D2R_max} / later than the fourth reference time point + _{T_D2R_max} ;

If at least part of the R2D transmission is later than _{T_D2R_max} (the end time) / outside _{T_D2R_max} / later than the fourth reference time point + _{T_D2R_max} , (as with A-IoT devices) at least part of the R2D transmission is discarded/abandoned/cancelled/skipped, or (as with A-IoT devices) a negative response (e.g., error or NACK or higher layer NACK) or a failure message is sent.

In some embodiments, the starting point of the second time interval is a fourth reference time point;

The fourth reference time point is determined based on at least one of the following: the time information of the second transmission associated with the first transmission, the time information of the control information corresponding to the first transmission, and the fourth time offset (delta 4).

The next or subsequent first transmission shall be performed no later than the fourth time interval, or the next or subsequent first transmission shall begin no later than the fourth time interval, or the next or subsequent first transmission shall end or stop no later than the fourth time interval, or the next or subsequent first transmission shall be completed no later than the fourth time interval.

The first transmission is not sent again after the fourth time interval, or at least a portion of the first transmission is not sent after the fourth time interval;

It is not expected that a specific portion of the first transmission in the next or subsequent transmission will be later than the fourth time interval;

It is not expected that a specific portion of the first transmission in the next or subsequent transmission will be later than the end of the fourth time interval;

If the processing time or time interval from the end of the first transmission to the start of the next or subsequent first transmission is greater than or equal to the fourth time interval, or if the sum of the preparation times of two consecutive first transmissions is greater than or equal to the fourth time interval, discard part or all of the next or subsequent first transmission, and/or send a negative acknowledgment or failure message, and/or send a delay message, and/or send time offset information, and/or send expected or supported time information, and/or determine whether to continue sending the first transmission, and/or determine the transmission method of the first transmission;

Discard part or all of the first transmission in the next or subsequent transmissions;

If at least part of the next or subsequent first transmission is later than the fourth time interval, or if at least part of the next or subsequent first transmission is later than the end of the fourth time interval, or if at least part of the next or subsequent first transmission is outside the fourth time interval, part or all of the next or subsequent first transmission is discarded.

The next or subsequent transmission of the first transmission is performed within the fourth time interval or before the end of the fourth time interval;

If at least a portion of the next or subsequent first transmission is later than the fourth time interval, or if at least a portion of the next or subsequent first transmission is later than the end of the fourth time interval, or if at least a portion of the next or subsequent first transmission is outside the fourth time interval, the next or subsequent first transmission shall be performed within the fourth time interval or before the end of the fourth time interval.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a fourth time interval as _{T_R2D_R2D_max} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is a reader, the first operation includes at least one of the following; or if the second device is a reader, the second operation includes at least one of the following:

(e.g., Reader) performs or begins (as in the next) R2D transmission/ends or completes (as in the next) R2D transmission no later than _{T_R2D_R2D_max} (the end time) / sixth reference time point + _{T_R2D_R2D_max} ; further optionally, all readers meet this requirement, or a specific reader meets this requirement, wherein the specific reader may be a reader that matches an ID (e.g., indicated by R2D transmission/control information), or the specific reader may be a reader of a specific type, or the specific reader may be a reader participating in a specific session; further optionally, if at least one or at least N readers do not meet the requirement, the test is considered to have failed, or the reader has failed to meet the timing requirements defined by the standard, or the associated R2D or R2D transmission has failed, or the associated control command has failed/ended, or the reader is inaccessible or untouchable;

(e.g., Reader) after _{T_R2D_R2D_max} (end) / after the sixth reference time point + _{T_R2D_R2D_max} , no longer respond to R2D transmissions / do not send at least part of the R2D transmission (as in the next time);

(e.g., Reader) does not expect at least part of the R2D transmission (e.g., start or end) to be later than _{T_R2D_R2D_max} (the end time) / sixth reference time point + _{T_R2D_R2D_max} ;

If the reader's processing time (e.g., the processing time from the "end" of R2D to the "start" or "end" of R2D, or the total time required for the reader to process R2D and prepare D2R) is greater than _{T_R2D_R2D_max} , then the reader's behavior (primarily for the case where the reader is a UE) includes at least one of the following:

Discard/abandon/cancel/skip at least part of the corresponding (as in the next) R2D transmission (such as Drop R2D);

The system will respond with a negative response (such as error, NACK, or higher layer NACK) or send a failure message.

Feedback delay message, for example, the reader anticipates that it cannot complete the next R2D (as in the next one), so it sends a delay message to postpone the next R2D;

Feedback offset message, the offset bit being the difference between the time the reader expects or can support and _{T_R2D_R2D_max} ;

Feedback time message/requirement, where the time message/requirement is the time that the reader expects or can support;

If the transmission of control information/R2D is a command (e.g., an inventory command) for a specific session (e.g., session 1), then the reader maintains its state for that session, or the reader maintains the session, or the reader does not modify its own state, or the reader suspends/pauses. Furthermore, if the terminal reader receives another command (e.g., an inventory command) for that session, then the reader can continue to participate in the inventory of that session.

It depends on the reader's implementation. For example, the reader can decide whether and/or how to continue the R2D transmission based on its own processing time capabilities.

(For example, if at least part of the next R2D transmission is outside of _{T_R2D_R2D_max} /later than the end of _{T_R2D_R2D_max} /after the sixth reference time point + _{T_R2D_R2D_max} ), (e.g., the reader) discards/abandons/cancels/skips at least part of the corresponding R2D transmission (this clause corresponds to the case where the reader has time to process, but for some reason the available R2D resources are outside the interval); for example, (e.g., the reader) discards/abandons/cancels/skips all R2D transmissions; for example, (e.g., the reader) discards/abandons/cancels/skips the part of the R2D transmission that is outside of _{T_R2D_R2D_max} /later than the end of _{T_R2D_R2D_max} /after the sixth reference time point + _{T_R2D_R2D_max} , (e.g., and/or, the remaining part can be transmitted);

(For example, if at least part of the R2D transmission is outside of _{T_R2D_R2D_max} /later than the end of _{T_R2D_R2D_max} /after the sixth reference time point + _{T_R2D_R2D_max} ), (such as the reader) sends the R2D transmission earlier within _{T_R2D_R2D_max} .

In some embodiments, the first time information includes the fourth time interval; when the first device is a second type of device, the first operation includes at least one of the following; and/or, when the second device is a second type of device, the second operation includes at least one of the following:

Detect or receive the next or subsequent first transmission;

Detect or receive the next or subsequent first transmission before the end of the fourth time interval, or detect or receive the next or subsequent first transmission within the fourth time interval;

Send a second transmission associated with the first transmission before the end of the fourth time interval, or send a first transmission associated with the first transmission during the fourth time interval;

The first transmission is not received or detected after the fourth time interval, or the first transmission is not received or detected outside the fourth time interval, or the first transmission is stopped after the fourth time interval, or the first transmission is stopped outside the fourth time interval;

If the next or subsequent first transmission is not received or only a portion of the next or subsequent first transmission is received, it is determined that the next or subsequent first transmission failed, or that the second transmission associated with the next or subsequent first transmission failed.

If, before the end of the fourth time interval, or within the fourth time interval, no next or subsequent first transmission is received, or only a portion of the next or subsequent first transmission is received, it is determined that the next or subsequent first transmission has failed, or that a second transmission associated with the next or subsequent first transmission has failed.

It is not expected that a specific portion of the next or subsequent first transmission will be later than the fourth time interval, or it is not expected that a specific portion of the next or subsequent first transmission will be later than the end of the fourth time interval;

If at least part of the next or subsequent first transmission is later than the fourth time interval, or if at least part of the next or subsequent first transmission is later than the end of the fourth time interval, or if at least part of the next or subsequent first transmission is outside the fourth time interval, discard part or all of the reception of the next or subsequent first transmission, and/or send a negative acknowledgment or failure message for the next or subsequent first transmission.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a fourth time interval as _{T_R2D_R2D_max} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is an A-IoT device, the first operation includes at least one of the following; or if the second device is an A-IoT device, the second operation includes at least one of the following:

(e.g., before _{T_R2D_R2D_max} (end) / within _{T_R2D_R2D_max} / before the sixth reference time point + _{T_R2D_R2D_max} ) the A-IoT device receives/detects (as next time) the R2D transmission;

(e.g., outside of _{T_R2D_R2D_max} / after _{T_R2D_R2D_max} / after the sixth reference time point + _{T_R2D_R2D_max} ) A-IoT devices no longer receive/no longer detect (the next) R2D transmissions, or stop receiving/stop detecting (the next) R2D transmissions;

(If the R2D transmission fails to be received (as in the next R2D transmission) before _{T_R2D_R2D_max} (end) / within _{T_R2D_R2D_max} / no earlier than the sixth reference time point + _{T_R2D_R2D_max} ), or only partially received (as in the next R2D transmission), the R2D transmission is considered to have failed.

(For example, A-IoT devices) do not expect (the next time) R2D transmission to be later than _{T_R2D_R2D_max} (the end time) / the sixth reference time point + _{T_R2D_R2D_max} ;

If (as in the next instance) at least part of the R2D transmission resource is later than the end time of _{T_R2D_R2D_max} , outside of _{T_R2D_R2D_max} , or at the sixth reference time point + _{T_R2D_R2D_max} , (e.g., an A-IoT device) discards/abandons/cancels/skips at least part of the R2D transmission reception, and/or (e.g., an A-IoT device) sends a negative acknowledgment (e.g., error, NACK, or higher layer NACK) or sends a failure message.

In some embodiments, the starting point of the fourth time interval is the sixth reference time point;

The sixth reference time point is determined based on at least one of the following: the time information of the last first transmission, and the sixth time offset.

Optionally, the time information of the last first transmission includes at least one of the following: the end time of the last first transmission, the start time of the last first transmission, and the transmission time of the last first transmission from the start time to the end time.

Optionally, the sixth time offset is agreed upon by a protocol, or the sixth time offset is determined by the first device, or the sixth time offset is configured by the second device.

For example, as shown in Figure 8, the second transmission is D2R, the fifth time interval can be _{T_D2R_D2R_min} , and the sixth time interval can be _{T_D2R_D2R_max} . For instance, _{T_D2R_D2R_min} can be the minimum time interval from D2R to the next or subsequent D2R, and _{T_D2R_D2R_max} can be the maximum time interval from D2R to the next or subsequent D2R. It should be noted that there may or may not be other transmissions between two D2Rs; this application does not limit this.

In some embodiments, the fifth time interval includes, but is not limited to, at least one of the following:

In some embodiments, the first time information includes the sixth time interval; when the first device is a second type of device, the first operation includes, but is not limited to, at least one of the following; and/or, when the second device is a second type of device, the second operation includes, but is not limited to, at least one of the following:

The next or subsequent second transmission shall be performed no later than the sixth time interval, or the next or subsequent second transmission shall begin no later than the sixth time interval, or the next or subsequent second transmission shall end or stop no later than the sixth time interval, or the next or subsequent second transmission shall be completed no later than the sixth time interval.

After the sixth time interval, no response is given to the first transmission, or the second transmission is not sent after the sixth time interval;

It is not expected that a specific portion of the next or subsequent second transmission will be later than the sixth time interval;

It is not expected that a specific portion of the next or subsequent second transmission will be later than the end of the sixth time interval;

If the processing time or time interval from the end of the second transmission to the start of the next or subsequent second transmission is greater than or equal to the sixth time interval, or if the sum of the preparation times of two consecutive second transmissions is greater than or equal to the sixth time interval, discard part or all of the next or subsequent second transmission, and/or send a negative acknowledgment or failure message, and/or send a delay message, and/or send time offset information, and/or send expected or supported time information, and/or determine whether to continue sending the second transmission, and/or determine the transmission method of the second transmission;

If the processing time or time interval from the end of the second transmission to the start of the next or subsequent second transmission is greater than or equal to the sixth time interval, or if the sum of the preparation times of two consecutive second transmissions is greater than or equal to the sixth time interval, and the control information corresponding to the second transmission includes a command for the fourth session or the second transmission includes a command for the fourth session, keep the state of the fourth session unchanged, or maintain the fourth session, or do not modify the state of the second type of device, or suspend or pause.

Discard part or all of the second transmission in the next or subsequent transmissions;

If at least part of the next or subsequent second transmission is later than the sixth time interval, or if at least part of the next or subsequent second transmission is later than the end of the sixth time interval, or if at least part of the next or subsequent second transmission is outside the sixth time interval, part or all of the next or subsequent second transmission shall be discarded.

The next or subsequent transmission of the second transmission shall be performed within the sixth time interval or before the end of the sixth time interval;

If at least a portion of the next or subsequent second transmission is later than the sixth time interval, or if at least a portion of the next or subsequent second transmission is later than the end of the sixth time interval, or if at least a portion of the next or subsequent first transmission is outside the sixth time interval, the next or subsequent second transmission shall be performed within the sixth time interval or before the end of the sixth time interval.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a sixth time interval as _{T_D2R_D2R_max} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is an A-IoT device, the first operation includes at least one of the following; or if the second device is an A-IoT device, the second operation includes at least one of the following:

(For example, A-IoT devices) begin or start D2R transmission/complete or end D2R transmission no later than _{T_D2R_D2R_max} (the end time) / the eighth reference time point + _{T_D2R_D2R_max} ; further optionally, all A-IoT devices meet this requirement, or a specific A-IoT device meets this requirement, wherein the specific A-IoT device may be an A-IoT device that matches the ID (e.g., indicated by R2D transmission/control information), or the specific A-IoT device may be a specific type of A-IoT device, or the specific A-IoT device may be an A-IoT device participating in a specific session; further optionally, if at least one or at least N A-IoT devices do not meet the requirement, the test is considered to have failed, or the A-IoT device has failed to meet the timing requirements defined by the standard, or the related D2R or R2D transmission has failed, or the related control command has failed/ended, or the A-IoT device is inaccessible or untouchable;

(For example, A-IoT devices) will no longer respond to (a certain associated) R2D transmission/will not send D2R transmissions after _{T_D2R_D2R_max} (end) / after the eighth reference time point + _{T_D2R_D2R_max} ;

(For example, A-IoT devices) do not expect (e.g., the next) D2R transmission to be later than _{T_D2R_D2R_max} (the end time) / the eighth reference time point + _{T_D2R_D2R_max} ;

(For example, assuming the A-IoT device transmits D2R no later than _{T_D2R_D2R_max} / eighth reference time point + _{T_D2R_D2R_max} ) If the processing time of the A-IoT device (e.g., the processing time from the end of the D2R transmission to the start of the D2R transmission or the terminal, or the total time required for the A-IoT device to prepare for D2R) is greater than _{T_D2R_D2R_max} (this corresponds to the case where the A-IoT device cannot process in time), then the behavior of the A-IoT device includes at least one of the following:

Discard/abandon/cancel/skip (e.g., the next) D2R transmission (e.g., Drop D2R); for example, (A-IoT device) discard/abandon/cancel/skip (e.g., the next) all D2R transmissions; or (e.g., A-IoT device) discard/abandon/cancel/skip (e.g., the next) part of the D2R transmission located within _{T_D2R_D2R_max} /before the end time of _{T_D2R_D2R_max} /before the eighth reference time point + _{T_D2R_D2R_max} (e.g., and/or, the remaining part may be transmitted);

The system will respond with a negative response (such as error, NACK, or higher layer NACK) or send a failure message.

Feedback delay messages, for example, when an A-IoT device is unable to complete D2R, it sends a delay message hoping to postpone the next R2D or D2R;

The feedback offset message is the difference between the time that the A-IoT device expects or can support and _{T_D2R_D2R_max} .

Feedback time message/requirement, wherein the time message/requirement is the time that the A-IoT device expects or can support;

If the transmission of a certain associated control information/R2D is for a certain session (such as session 1) (e.g., an inventory command), then the A-IoT device maintains the state of that session unchanged, or the A-IoT device maintains the session, or the A-IoT device does not modify its own state, or the A-IoT device suspends/pauses; furthermore, if the terminal A-IoT device receives another command for that session (e.g., an inventory command), then the A-IoT device can continue to participate in the inventory of that session;

It depends on the implementation of the A-IoT device. For example, the A-IoT device can decide whether and/or how to continue the D2R transmission based on its own processing time capability.

If (e.g., at least part of the next D2R transmission is outside of _{T_D2R_D2R_max} /later than the end time of _{T_D2R_D2R_max} /after the eighth reference time point + _{T_D2R_D2R_max} ), (e.g., the A-IoT device) discards/abandons/cancels/skips at least part of the corresponding D2R transmission (this clause corresponds to the case where the A-IoT device has time to process, but the resources are outside the interval); for example, (e.g., the A-IoT device) discards/abandons/cancels/skips the entire (e.g., the next) D2R transmission; or, for example, (e.g., the A-IoT device) discards/abandons/cancels/skips the part of (e.g., the next) D2R transmission that is outside of _{T_D2R_D2R_max} /later than the end time of _{T_D2R_D2R_max} /after the eighth reference time point + _{T_D2R_D2R_max} ), (e.g., and/or, the remaining part can be transmitted);

If (e.g., at least part of the next D2R transmission is outside _{T_D2R_D2R_max} / later than the end of _{T_D2R_D2R_max} / after the eighth reference time point + _{T_D2R_D2R_max} ), (e.g., an A-IoT device) sends the (e.g., the next) D2R transmission earlier than _{T_D2R_D2R_max} .

In some embodiments, the first time information includes the sixth time interval; when the first device is a device of the first type, the first operation includes, but is not limited to, at least one of the following; and/or, when the second device is a device of the first type, the second operation includes, but is not limited to, at least one of the following:

Detect or receive the next or subsequent second transmission;

Detect or receive the next or subsequent second transmission before the end of the sixth time interval, or detect or receive the next or subsequent second transmission within the sixth time interval;

Send the first transmission associated with the second transmission before the end of the sixth time interval, or send the first transmission associated with the second transmission within the sixth time interval;

The second transmission is not received or detected after the sixth time interval, or is not received or detected outside the sixth time interval, or the second transmission is stopped after the sixth time interval, or the second transmission is stopped outside the sixth time interval;

If the next or subsequent second transmission is not received or only a portion of the next or subsequent second transmission is received, it is determined that the next or subsequent second transmission failed, or the first transmission associated with the next or subsequent second transmission failed.

If, before the end of the sixth time interval, or within the sixth time interval, no next or subsequent second transmission is received, or only a portion of the next or subsequent second transmission is received, it is determined that the next or subsequent second transmission has failed, or that the first transmission associated with the next or subsequent second transmission has failed.

It is not expected that a specific portion of the next or subsequent second transmission will be later than the sixth time interval, or that a specific portion of the next or subsequent second transmission will be later than the end of the sixth time interval;

If at least part of the next or subsequent second transmission is later than the sixth time interval, or if at least part of the next or subsequent second transmission is later than the end of the sixth time interval, or if at least part of the next or subsequent second transmission is outside the sixth time interval, discard part or all of the reception of the next or subsequent second transmission, and/or send a negative acknowledgment or failure message for the next or subsequent second transmission.

For example, taking a first type of device as a reader, a second type of device as an A-IoT device, a first transmission as R2D, a second transmission as D2R, and a sixth time interval as _{T_D2R_D2R_max} as an example, the descriptions in parentheses are explanatory or optional features, and "/" indicates and/or. Specifically, if the first device is a reader, the first operation includes at least one of the following; or if the second device is a reader, the second operation includes at least one of the following:

(For example, before _{T_D2R_D2R_max} (end) / within _{T_D2R_D2R_max} / before the eighth reference time point + _{T_D2R_D2R_max} ) The Reader receives/detects (for example, the next) D2R transmission;

(For example, before _{T_D2R_D2R_max} (end) / within _{T_D2R_D2R_max} / before the eighth reference time point + _{T_D2R_D2R_max} ) the Reader sends R2D transmission;

(For example, outside of _{T_D2R_D2R_max} / after _{T_D2R_D2R_max} / after the eighth reference time point + _{T_D2R_D2R_max} ) The Reader no longer receives/detects (the next) D2R transmission, or stops receiving/detecting (for example, the next) D2R transmission;

(For example, before _{T_D2R_D2R_max} (end) / within _{T_D2R_D2R_max} / no earlier than the eighth reference time point + _{T_D2R_D2R_max} ), if the Reader does not receive (e.g., the next) D2R transmission from the device or only receives a portion (e.g., the next) D2R transmission, then it is considered that a certain associated R2D transmission has failed, and/or, the D2R transmission has failed;

(For example, the Reader) does not expect (e.g., scheduled/instructed) D2R transmissions to be later than _{T_D2R_D2R_max} (the end time) / the eighth reference time point + _{T_D2R_D2R_max} ;

If (e.g., instructed/informed) at least a portion of the D2R transmission resource is later than the end time of _{T_D2R_D2R_max} , outside of _{T_D2R_D2R_max} , or at the eighth reference time point + _{T_D2R_D2R_max} , (e.g., the reader) discards/abandons/cancels/skips at least a portion of the D2R transmission reception; for example, (e.g., the reader) discards/abandons/cancels/skips the reception of the D2R transmission; or, for example, (e.g., the reader) discards/abandons/cancels/skips the reception of the portion of the D2R transmission located outside of _{T_D2R_D2R_max} , earlier than the end time of _{T_D2R_D2R_max} , or after the eighth reference time point + _{T_D2R_D2R_max} , (e.g., and/or, the remaining portion may be received).

In some embodiments, the starting point of the sixth time interval is the eighth reference time point;
