Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0144] In the related art, Internet of Things (IoT) devices are usually powered by traditional batteries with limited lifetimes, which negatively impacts user experience. The astronomical growth of IoT networks, coupled with the emergence of a large number of IoT devices, pushes the maintenance expenditure, including labor and battery costs, to a whole new level. Billions of traditional batteries are discarded every year, only a small fraction of which can be effectively recycled, which has a harmful impact on the Earth's ecosystem. In some extreme environmental conditions, it can be very challenging to maintain the operation of IoT networks and replace batteries. In view of this, related research expects to propose a battery-free IoT communication to improve network performance and sustainability, and expand application scenarios. In addition, battery-free communication is more environmentally friendly and safer for children and the elderly. By removing traditional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications. And the IoT supporting environmental power, i.e., passive IoT, is a promising technology that can meet the above needs.

[0145] In some embodiments, the A-IOT devices (or Device) in the passive IoT system can be divided into three types: Device A, Device B and Device C. Among them, Device A has no energy storage, no independent signal generation and signal amplification, and needs to rely on back scattering technology to realize data transmission; Device B has energy storage, but no independent signal generation, and needs to rely on back scattering technology to realize data transmission, and the stored energy can be used to amplify the reflected signal; Device C has energy storage and has independent signal generation, that is, Device C has an active Radio Frequency (RF) component for transmission, and can realize data transmission through active transmission.

[0146] In some embodiments, the passive IoT design needs to support non-activate Devices (i.e., Device A and Device B), which do not have RF transmission capabilities and need to obtain transmission energy through back scattering.

[0147] And in some embodiments, the passive IoT device also needs to support basic use cases such as tag inventory business.

[0148] In some embodiments, the tag inventory process can rely on select command sets, inventory command sets, access command sets, etc.

[0149] In some embodiments, in the A-IOT system, in addition to the need to support inventory business, it is also necessary to support sending corresponding Reader to Device (R2D) commands by one or more A-IOT devices for one or more A-IOT devices to implement read, write, kill, and the like operations.

[0150] In some embodiments, for uplink transmission in A-IOT (i.e., D2R transmission), in order to enhance reliability and uplink coverage, corresponding repetition can be configured for D2R transmission.

[0151] In some embodiments, A-IOT can support bit-level repetition, which repeats each bit in a TB N times, and then performs corresponding encoding and modulation processes.

[0152] In some embodiments, A-IOT can support Terabyte (TB)-level repetition, which transmits each TB multiple times, and the receiving end can combine the reception to obtain gain.

[0153] In the related art, the Reader can correctly decode the current data packet before the A-IOT device completes the indicated or pre-configured number of repetitions, and at this time, the A-IOT device continues to perform repetition transmission, which increases power consumption of the A-IOT device and overall transmission delay, so the A-IOT D2R transmission early termination mechanism can be considered to reduce the impact of the above situation.

[0154] That is, the embodiments of the present disclosure expect to provide an early termination repetition transmission mechanism in A-IOT, so that the repetition transmission of the A-IOT device can be terminated early when the A-IOT device performs D2R repetition transmission, the number of repetitions is reduced, unnecessary power consumption is avoided, and additional delay is generated.

[0155] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiments of the present disclosure relate to a communication method, and the method includes:

[0156] In step S2101, the A-IOT device sends a first message to the first communication device.

[0157] In some embodiments, the first communication device can receive the first message sent by the A-IOT device.

[0158] In some embodiments, the first message can be used to implement a D2R transmission from the A-IOT device (i.e., Device) to the first communication device (i.e., Reader).

[0159] In some embodiments, the name of the first message is not limited, which is, for example, "D2R message", "D2R transmission", "Physical Device to Reader Channel (PDRCH) transmission", etc.

[0160] In some embodiments, the sending of the first message can be repeated, that is, the A-IOT device can repeatedly send the first message to the first communication device.

[0161] In some embodiments, the first communication device can receive the first message repeatedly sent by the A-IOT device.

[0162] In some embodiments, the repeated sending of the first message can be TB-level repeated sending.

[0163] In some embodiments, the names of messages and the like are not limited to the names described in the embodiments, and the terms "message", "information", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "code point", "bit", "data", "program", "chip", and the like can be replaced with each other.

[0164] Step S2102: The A-IOT device determines to discard the remaining repeated sending based on the first information.

[0165] In some embodiments, the first information is used to indicate information related to the state and / or performance of the A-IOT device, and / or the first information is used to indicate that the A-IOT device receives a second message sent by the first communication device within a first time duration after repeatedly sending the first message.

[0166] The following will introduce the cases where the first information indicates different contents respectively.

[0167] Firstly, the case that the first information is used to indicate that the A-IOT device receives the second message sent by the first communication device within the first time length after repeatedly sending the first message is introduced.

[0168] In some embodiments, the first time length can be reserved between multiple repeated sending.

[0169] In some embodiments, whether to reserve the first time length between multiple repeated sending can be determined by the A-IOT device.

[0170] In some embodiments, the A-IOT device can determine whether to reserve the first time length between multiple repeated sending based on the first indication information.

[0171] In some embodiments, the first indication information can be used to indicate whether to reserve the first time length between multiple repeated sending.

[0172] In some embodiments, the name of the first indication information is not limited, which is, for example, "first indication", "control information", etc.

[0173] In some embodiments, the first indication information can be sent by the first communication device to the A-IOT device, and the A-IOT device can receive the first indication information sent by the first communication device.

[0174] In some embodiments, the first communication device can send a third message to the A-IOT device, and the third message includes the first indication information.

[0175] In some embodiments, the third message can be used to schedule the A-IOT device to send the first message to the first communication device.

[0176] In some embodiments, the name of the third message is not limited, which is, for example, "R2D message" and the like.

[0177] In some embodiments, the first indication information can also be used to indicate the way of reserving the first time length between multiple repeated sending.

[0178] In some embodiments, the first indication information can be used to indicate the number of repetitions of the interval between two adjacent first time durations. For example, the first indication information can be used to indicate that the number of repetitions of the interval between two adjacent first time durations is 1, so that the first indication information can be used to indicate that one first time duration is reserved after each repetition; for another example, the first indication information can be used to indicate that the number of repetitions of the interval between two adjacent first time durations is 2, so that the first indication information can be used to indicate that one first time duration is reserved after every two repetitions; for another example, the first indication information can be used to indicate that the number of repetitions of the interval between two adjacent first time durations is 3, so that the first indication information can be used to indicate that one first time duration is reserved after every three repetitions, and the like, but not limited thereto.

[0179] In some embodiments, the first indication information can be used to indicate index information, and the index information can be associated with a manner of reserving the first time duration between the multiple repetitions. Taking the number of repetitions as 4 for example, the manner of reserving the first time duration between the multiple repetitions can be index#0=[RP#0, gap, RP#1, gap, RP#2, gap, RP#3], index#1=[RP#0, RP#1, gap, RP#2, RP#3], and the like, and the index information (i.e., index#0, index#1, and the like) can be indicated by the first indication information, so as to indicate the manner of reserving the first time duration between the multiple repetitions.

[0180] In some embodiments, the A-IOT device can further determine whether to reserve the first time duration between the multiple repetitions based on the second information.

[0181] In some embodiments, the second information can be used to indicate the length of the first message, so as to implicitly associate the relationship between the sending of the first message and whether to reserve the first time duration between the multiple repetitions.

[0182] In some embodiments, the name of the second information is not limited, which is, for example, “message sending length information” and the like.

[0183] In some embodiments, when the length of the first message is greater than or equal to a first threshold, the A-IOT device can determine to reserve the first time duration between the multiple repetitions.

[0184] In some embodiments, the length of the first message can be the number of chips of the sent first message, but not limited thereto.

[0185] It should be noted that whether to reserve the first time duration between the multiple repetitions can also be referred to as “whether the first time duration is enabled” and the like, but not limited thereto.

[0186] In some embodiments, the name of the first time duration is not limited, for example, it is "gap time" or the like.

[0187] In some embodiments, the terms "time duration", "time period", "time window", "window", "time" and the like can be replaced with each other, and the terms "time", "time point", "time point", "time position" and the like can be replaced with each other.

[0188] In some embodiments, the first time duration can be determined based on the maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message.

[0189] In some embodiments, the first time duration is the maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message. That is, the first time duration can be T D2R_max , T D2R_max represents the maximum time for waiting for the next second message after sending the first message.

[0190] In some embodiments, the first time duration is the sum of the maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message and a first margin value determined based on the SFO of the A-IOT device. That is, the first time duration can be T D2R_max + delta, wherein T D2R_max represents the maximum time for waiting for the next second message after sending the first message, and delta represents the first margin value determined based on the SFO of the A-IOT device.

[0191] In some embodiments, the first margin value can be determined based on the maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message and a first proportion parameter.

[0192] In some embodiments, the first margin value is the product of the maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message and the first proportion parameter, or the product ± n1, and the like, n1 is a real number, but not limited thereto.

[0193] In some embodiments, the first proportion parameter can be 0.1, 0.01, 0.001, 0.0001, and the like, but not limited thereto. That is, the first margin value determined based on the SFO of the A-IOT device can be T D2R_max multiplied by 0.1, 0.01, 0.001, 0.0001, and the like.

[0194] In some embodiments, the second message can be used to implement R2D transmission from the first communication device (i.e., Reader) to the A-IOT device (i.e., Device).

[0195] In some embodiments, the name of the second message is not limited, and may be, for example, “R2D message”, “R2D transmission”, “Physical R2D channel (Physical Reader to Device Channel, PRDCH) transmission”, etc.

[0196] In some embodiments, the A-IoT device can detect a second message sent by the first communication device within a first time period after the first message is sent, wherein the first time period is determined based on a first duration.

[0197] In some embodiments, the first time period may be a time period that starts with the shortest time after the A-IoT device sends the first message and waits to receive the second message sent by the first communication device, and ends with the longest time after the A-IoT device sends the first message and waits to receive the second message sent by the first communication device.

[0198] That is, the first time period can be [T] D2R_min ,T D2R_max ], where T D2R_min T represents the shortest time T takes for an A-IoT device to wait to receive a second message from a first communication device after sending the first message. D2R_max This indicates the maximum time an A-IoT device waits to receive a second message from a first communication device after sending the first message.

[0199] In some embodiments, the first time period is the difference between the shortest time for waiting to receive the second message sent by the first communication device after the A-IoT device sends the first message and the second margin value determined based on the SFO of the A-IoT device, which is the start time, and the sum of the longest time for waiting to receive the second message sent by the first communication device after the A-IoT device sends the first message and the third margin value determined based on the SFO of the A-IoT device, which is the end time.

[0200] That is, the first time period can be [T] D2R_min -delta_1,T D2R_max +delta_2], where T D2R_min This represents the shortest time that the A-IoT device waits to receive the second message from the first communication device after sending the first message. delta_1 represents the second margin value determined based on the SFO of the A-IoT device. D2R_maxrepresents a maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message, and delta_2 represents a third margin value determined based on the SFO of the A-IOT device.

[0201] In some embodiments, the second margin value can be determined based on a minimum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message and a second proportional parameter.

[0202] In some embodiments, the second margin value is a product of the minimum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message and the second proportional parameter, or a product ±n2, where n2 is a real number, but not limited thereto.

[0203] In some embodiments, the second proportional parameter can be 0.1, 0.01, 0.001, 0.0001, etc., but not limited thereto. That is, the second margin value determined based on the SFO of the A-IOT device can be T D2R_min multiplied by 0.1, 0.01, 0.001, 0.0001, etc.

[0204] In some embodiments, the third margin value can be determined based on a maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message and a third proportional parameter.

[0205] In some embodiments, the third margin value can be a product of the maximum time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message and the third proportional parameter, or a product ±n3, where n3 is a real number, but not limited thereto.

[0206] In some embodiments, the third proportional parameter can be 0.1, 0.01, 0.001, 0.0001, etc., but not limited thereto. That is, the third margin value determined based on the SFO of the A-IOT device can be T D2R_max multiplied by 0.1, 0.01, 0.001, 0.0001, etc.

[0207] In some embodiments, the name of the first time period is not limited, which is, for example, “a first time window”, etc.

[0208] The case that the first information is used to indicate information related to the state and / or performance of the A-IOT device is introduced below.

[0283] The optional implementation of step S3201 can refer to the optional implementation of step S2101 in FIG. 2 and other associated parts in the embodiments involved in FIG. 2, which will not be described here.

[0284] In some embodiments, the A-IOT device repeatedly sends the first message to the first communication device.

[0288] In step S3203, the A-IOT device determines to discard the remaining repetitions and sends second indication information to the first communication device.

[0289] The optional implementation of step S3203 can refer to the optional implementation of step S2102 in FIG. 2 and other associated parts in the embodiments involved in FIG. 2, which will not be described here.

[0290] In some embodiments, the second indication information is used to indicate that the remaining repetitions have been discarded.

[0291] In some embodiments, the A-IOT device can send a fourth message to the first communication device, and the fourth message can include the second indication information.

[0292] In some embodiments, the second indication information can be high layer signaling carried by the fourth message, or the second indication information can be physical layer control information carried by the fourth message.

[0293] At step S3204, the A-IOT device detects the second message sent by the first communication device within a second time period.

[0294] In some embodiments, the second time period can be determined based on the first time length.

[0295] In some embodiments, the second time period can be a time period starting from the shortest time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message, and ending at the longest time for the A-IOT device to wait for receiving the second message sent by the first communication device after sending the first message.

[0296] In some embodiments, the second message is used to indicate that the first communication device has successfully received the first message, or the second message is used to indicate that the first communication device has not successfully received the first message.

[0297] In some embodiments, when the second message is used to indicate that the first communication device has not successfully received the first message, the A-IOT device can directly discard the remaining repeated sending without continuing the repeated sending of the first message.

[0298] In some embodiments, when the second message is used to indicate that the first communication device has not successfully received the first message, the A-IOT device can trigger a random access retry mechanism after discarding the remaining repeated sending, or the A-IOT device can continue the repeated sending of the first message based on the remaining number of repeated sending after discarding the remaining repeated sending.

[0299] The communication method related to the embodiments of the present disclosure can include at least one of steps S3201-S3204. For example, step S3202 can be implemented as an independent embodiment, step S3203 can be implemented as an independent embodiment, steps S3201+S3202 can be implemented as an independent embodiment, steps S3201+S3203 can be implemented as an independent embodiment, steps S3202+S3203 can be implemented as an independent embodiment, steps S3202+S3204 can be implemented as an independent embodiment, steps S3203+S3204 can be implemented as an independent embodiment, steps S3201+S3202+S3203 can be implemented as an independent embodiment, steps S3201+S3202+S3204 can be implemented as an independent embodiment, steps S3201+S3203+S3204 can be implemented as an independent embodiment, steps S3202+S3203+S3204 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0300] In some embodiments, steps S3203 and S3204 can be exchanged in order or performed simultaneously.

[0301] In some embodiments, steps S3201, S3203, and S3204 are optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0302] In some embodiments, steps S3201, S3202, and S3204 are optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0303] The embodiments of the present disclosure provide an early termination of repeated transmission mechanism in A-IOT, which can early terminate the repeated transmission of Device (i.e., A-IOT device), reduce the number of repetitions, avoid unnecessary power consumption, and produce additional delay.

[0304] Option 1: When Device performs multiple repeated sending of data packets, a gap of a certain length can be reserved between different repeated sending.

[0305] In some embodiments, the length of the gap is a first time length, and the first time length is T D2R_max ; wherein T D2R_max is the maximum time that Device waits for the next R2D transmission (i.e., PRDCH) after sending D2R transmission (i.e., PDRCH).

[0306] In some embodiments, the first time length can be TD2R_max+delta, where delta is a value considering the margin of SFO of Device, which can have a value of T D2R_max times 0.1, 0.01, 0.001, 0.0001, etc.

[0307] In some embodiments, the gap can be indicated by control information in the R2D message scheduling the current D2R transmission, whether to enable, if indicated to enable, the Device reserves the above-mentioned gap between each repetition when performing PDRCH repetition transmission, otherwise, no gap reservation is performed.

[0308] In some embodiments, the indication information for indicating whether the gap is enabled only takes effect when the corresponding R2D transmission indicates repetition transmission.

[0309] In some embodiments, the indication information for indicating whether the gap is enabled can also indicate the pattern of gap reservation. For example, when the number of repetitions is 4, the information can indicate one or several of the following possible configurations, which can be achieved by indicating the index by numbering the following possible patterns: index#0=[RP#0, gap, RP#1, gap, RP#2, gap, RP#3], index#1=[RP#0, RP#1, gap, RP#2, RP#3], and so on.

[0310] Alternatively, the relationship between the transmission of PDRCH and whether the gap is enabled can be implicitly associated, for example, only when the number of chips (i.e. the transmission length) of PDRCH is greater than or equal to a threshold, the gap can be enabled, or can be indicated to be enabled.

[0311] In some embodiments, if the corresponding R2D transmission (such as Msg 2) is received within a time period [T D2R_min , T D2R_max ] after the completion of a repetition transmission, the Device terminates the repetition transmission of PDRCH, i.e. discards or cancels the subsequent repetition transmission times and does not perform subsequent transmission.

[0312] In some embodiments, the above-mentioned time period can also be [T D2R_min -delta_1, T D2R_max +delta_2], where delta_1 is a value considering the margin of SFO of Device, which can have a value of T D2R_mintimes 0.1, 0.01, 0.001, 0.0001, etc. D2R_max times 0.1, 0.01, 0.001, 0.0001, etc.

[0313] In some embodiments, if the received msg 2 is NACK, a re-attempt mechanism of random access is triggered, such as reselecting an occasion of access for a random access process.

[0314] Alternatively, the above-mentioned early termination process is only performed in the case of receiving ACK, and in the case of receiving NACK, after decoding the R2D transmission, the subsequent number of repetition transmissions is continued.

[0315] Scheme two: Device indication early termination mechanism.

[0316] In some embodiments, the Device performs repetition of D2R transmission based on the indication of the reader.

[0317] In some embodiments, in one repetition transmission, the Device can indicate that the current repetition transmission is “early termination”, and after the current transmission, the Device detects the corresponding R2D transmission information (such as Msg 2) within a time period [T D2R_min , T D2R_max ], and after correct decoding, cancels the subsequent number of repetition transmissions.

[0318] In some embodiments, the Device can determine the reporting of the information indicating that the current repetition transmission is “early termination” according to its own power and / or service type information, etc.

[0319] In some embodiments, the information indicating that the current repetition transmission is “early termination” can be high-layer signaling carried by PDRCH, or L1 D2R control information carried thereby.

[0320] In some embodiments, the above-mentioned mechanism is only effective when the current PDRCH is configured with TB-level repetition.
