[0004] In communication systems, the end position of transmissions sent by the transmitting end is often not fixed. For example, the end position of a reader-to-device (R2D) transmission sent by a reader to a device is not fixed, nor is the end position of a device-to-reader (D2R) transmission sent by the device to a reader. In some related technologies, the receiving end cannot determine the end position of the transmission, which can lead to demodulation errors and poor reception performance.

Network-side equipment 12 may include access network equipment or core network equipment, wherein access network equipment may also be referred to as Radio Access Network (RAN) equipment, radio access network function, or radio access network unit.

The term "base station" is not limited to specific technical terms. It should be noted that the embodiments of this application only use the base station in the NR system as an example for introduction, and do not limit the specific type of base station.

[0052] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), and Binding Support.

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

[0053] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0054] In this application embodiment, the device can be an Internet of Things (IoT) device, such as an Ambient IoT (A-IoT) device. The A-IoT device can be characterized based on its energy storage capacity and its ability to generate and transmit radio frequency signals. A-IoT devices include the following types:

[0055] Device 1: No energy storage, no independent signal generation / amplification, i.e., backscatter transmission.

[0056] Device 2a: It has energy storage but no independent signal generation, i.e., backscatter transmission. The use of the stored energy may include amplification of the reflected signal.

[0057] Device 2b: It has energy storage and independent signal generation, i.e., an active radio frequency component for transmission.

[0058] 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.

[0059] A-IoT can be deployed in various scenarios, and two of them are introduced below.

[0060] As shown in Topology 1 of Figure 2, in this scenario, A-IoT base stations (BS) and A-IoT devices communicate directly to transmit A-IoT data and signaling. The base station sending A-IoT R2D transmissions (also known as R2D signals) and the base station receiving A-IoT D2R transmission signals can be the same or different.

[0061] As shown in Topology 2 of Figure 3, in this scenario, the AI ​​IoT BS communicates with A-IoT devices through intermediate nodes. These intermediate nodes can be terminals, repeaters, relays, or Integrated Access and Backhaul (IAB) nodes. The BS can control the intermediate nodes via air interface signaling or other interfaces; for example, the BS can control the terminals through the NR Uu air interface.

[0062] In some embodiments, A-IoT command types include inventory and command;

[0063] Inventory is the most basic and important business of A-IoT, which enables A-IoT servers to learn about one or more known or unknown A-IoT devices within the reader's coverage area through the 3rd Generation Partnership Project (3GPP) network.

[0064] After learning that an A-IoT device has been identified by the network, the A-IoT server may be able to issue commands to the device via the network, such as those shown in Table 1 below:

[0065] Table 1:

[0066] In some embodiments, the main data / service types of A-IoT include:

[0067] Device-originated (DO);

[0068] Device-terminated (DT);

[0069] DO and DT data indicate that the data stream originates from or is transmitted to an A-IoT device (similar to a Radio Frequency Identification (RFID) tag). For data streams originating from A-IoT devices, i.e., DO data, further classification is as follows:

[0070] Device-originated access (DOA) means that the device autonomously initiates data transmission. For example, it connects a large number of various sensors, which collect and proactively report information about the environment, the device, and the organism when necessary.

[0071] Device-originated–device-terminated triggered (DO-DTT) means that data transmission is triggered by the termination of data. Examples include asset identification, status reporting, and tracking, all of which involve downlink-triggered reporting. The reader collects data from the tag by triggering an inventory procedure. Since the data is generated / initiated within the A-IoT device, this service should be considered as a DO service triggered by a command sent by the reader.

[0072] In some embodiments, the general A-IoT process is shown in Figure 4, including the following steps:

[0073] Step A, A-IoT paging, is when the reader sends an A-IoT paging message to the device;

[0074] Step B, Device-to-Reader (D2R) data transmission, includes D2R data transmission and may also include an A-IoT random access procedure;

[0075] Step C, data transmission, can include R2D data transmission and D2R data transmission.

[0076] The inventory-only process includes: Step A + Step B;

[0077] The inventory and command process includes: Step A + Step B + Step C.

[0078] In some embodiments, Manchester encoding may be used, which uses high-to-low level switching to represent "0" or "1".

[0079] The encoding rules are shown in Figure 5. In the signal bit, a transition from low to high level represents 0, and a transition from high to low level represents 1.

[0080] Or, conversely, a jump from low to high represents 1, and a jump from high to low represents 0.

[0081] The following description, in conjunction with the accompanying drawings, details the transmission method, apparatus, device, storage medium, and program product provided in this application through some embodiments and application scenarios.

[0082] Please refer to Figure 6, which is a flowchart of a transmission method provided in an embodiment of this application. As shown in Figure 6, it includes the following steps:

[0083] Step 601: The receiving end determines the end position of the first transmission based on at least one of the first information and the first event, wherein the first information is related information of the first transmission and the first event is used to determine the end position.

[0084] In this embodiment, the receiving end can be a reader / writer, which can be a terminal or a network-side device, and the corresponding sending end is an Internet of Things (IoT) device or an A-IoT device (hereinafter referred to as a Device); or, the receiving end can be an IoT device or an A-IoT device (hereinafter referred to as a Device), and the corresponding sending end is a reader / writer; or, in some embodiments, it can also be applied to non-A-IoT scenarios, where the receiving end can be a network-side device, and the sending end is a terminal, or, where the receiving end is a terminal, the sending end is a network-side device.

[0085] In some implementations, the first transmission is a D2R transmission and the receiving end is a reader / writer; or, the first transmission is an R2D transmission and the receiving end is an A-IoT device or device.

[0086] The aforementioned first information is related information of the first transmission, which may be information carried in the first transmission, parameter information of the first transmission, or information carried in signaling related to the first transmission.

[0087] The aforementioned first event can be a matter agreed upon in the protocol or configured by the network-side device. For example, it could be determining the end position based on the parameters of the first transmission or based on the content carried in the first transmission. For instance, the first event could include detecting signal parameters that differ from the transmission end position before the end position, and determining whether it is an end position based on these signal parameters.

[0088] Step 602: The receiving end performs at least one of the following actions based on the end position: determining the transmission length of the first transmission and receiving the first transmission.

[0089] The transmission length of the first transmission can also be referred to as the data size of the first transmission, such as the transport block size (TBS).

[0090] Step 602 above includes at least one of the following:

[0091] The receiving end determines the transmission length of the first transmission based on the end position;

[0092] The receiving end receives the first transmission according to the end position;

[0093] The receiving end determines the transmission length of the first transmission based on the end position, and receives the first transmission.

[0094] In some implementations, determining the transmission length of the first transmission based on the end position may be based on the end position and the start position of the first transmission, or based on the end position and the reference position.

[0095] In some implementations, receiving the first transmission according to the end position may be receiving the first transmission at the end position.

[0096] It should be noted that, in this embodiment, if step 602 does not include determining the transmission length of the first transmission based on the end position, the transmission length of the first transmission can be determined based on the first indication information described in the following embodiments, or the transmission length of the first transmission can be agreed upon by the protocol. If step 602 does not include receiving the first transmission based on the end position, the receiving end can receive the first transmission based on the transmission length of the first transmission. In this way, the receiving end does not need to continue listening after the end position, thereby saving the power consumption of the receiving end. In this embodiment, since the end position of the first transmission is determined based on at least one of the first information and the first event, and then the transmission length of the first transmission and / or the first transmission is received based on the end position, the transmission length of the first transmission and / or the first transmission is determined based on the end position. This can avoid demodulation errors at the receiving end, thereby improving the receiving performance of the receiving terminal. This ensures that the receiving end can correctly demodulate the content carried by the first transmission.

[0097] As an optional implementation, the method further includes:

[0098] The receiving end receives the second information;

[0099] The receiving end determines the method for determining the end position of the first transmission based on the second information;

[0100] The second information is used to indicate the determination method, which includes the following:

[0101] Determine the end position based on the first information and the first event;

[0102] Determine the end position based on the first information;

[0103] The end position is determined based on the first event.

[0104] The second information may be carried in the first transmission or received through a transmission other than the first transmission.

[0105] The second piece of information mentioned above may be an explicit or implicit indication of the determination method.

[0106] The above-mentioned determination of the end position based on the first information and the first event can be based on the first information and the first event to jointly determine the end position of the first transmission, such as determining the length of each transmission of the first transmission based on the first information, and then determining the last transmission based on the first event.

[0107] The above-mentioned determination of the end position based on the first information can be based on determining the length of the first transmission based on the first information, and then determining the end position of the first transmission based on the length, such as determining the length of each transmission, so that the end position of each transmission is determined, or the last transmission can be determined based on the mapping relationship between the transmission length and the last transmission, such as different transmission lengths corresponding to different transmission numbers.

[0108] The above-mentioned determination of the end position based on the first event can be based on the first event to determine the last transmission of the first transmission, and then determine the end position of the first position.

[0109] In the above embodiments, since the second information indicates the determination method, the end position of the first transmission is determined according to the determination method. This allows for a better understanding of the end position of the first transmission, ensuring that the receiving end and the sending end have a consistent understanding of the end position, and also supports dynamic changes in the determination method.

[0110] In some implementations, the above determination method may also be agreed upon in advance or by default, and there is no limitation on this.

[0111] As an optional implementation, the first information mentioned above includes at least one of the following:

[0112] The content of the first transmission, the type of the first transmission, whether the first transmission carries a cyclic redundancy check (CRC), whether the first transmission uses repeated transmission, the number of repetitions of the first transmission, whether the first transmission uses forward error correction (FEC), the signal format information of the first transmission, and the first indication information, the first indication information being used to indicate at least one of the following: the transmission length of the first transmission and whether the first transmission includes a postamble.

[0113] The signal format information includes at least one of the following:

[0114] Encoding method, modulation method, signal bandwidth, center frequency.

[0115] The content of the first transmission is the content carried in the first transmission. Different contents may correspond to different end positions or different transmission lengths. The end position of the first transmission can be determined directly or indirectly based on the content of the first transmission.

[0116] The type of the first transmission can be the message type of the first transmission, such as a command or inventory. Different types may correspond to different end positions or different transmission lengths. The end position of the first transmission can be determined directly or indirectly based on the type of the first transmission.

[0117] The first transmission carrying CRC and different CRC carrying can indicate whether the first transmission ends or does not end, or carrying CRC and not carrying CRC can correspond to different transmission lengths. The end position of the first transmission can be directly or indirectly determined based on whether the first transmission carries CRC.

[0118] The first transmission described above can correspond to different transmission lengths depending on whether it uses repeated transmission or not. The end position of the first transmission can be determined directly or indirectly based on whether repeated transmission is used.

[0119] In the case of repeated transmissions, the transmission length or end position can be determined based on the number of repetitions. For example, the transmission length or end position corresponding to different numbers of repetitions is agreed upon by the protocol or configured by the network-side device.

[0120] The use of FEC and the absence of FEC in the first transmission can indicate whether the first transmission has ended or not, or the use of FEC and the absence of FEC can correspond to different transmission lengths. The end position of the first transmission can be directly or indirectly determined based on whether FEC is used in the first transmission.

[0121] The above encoding method can be FM0 encoding, Miller encoding, Manchester encoding or non-linear encoding (no-line code). Different encoding methods correspond to different end positions or transmission lengths. The end position of the first transmission is determined directly or indirectly based on the encoding method.

[0122] The modulation method mentioned above can be ON-OFF Keying (OOK), Amplitude-shift keying (ASK), Minimum Shift Keying (MSK), Frequency Shift Keying (FSK), or Binary Phase Shift Keying (BPSK). Different modulation methods correspond to different end positions or transmission lengths, and the end position of the first transmission is determined directly or indirectly based on the modulation method.

[0123] Different signal bandwidths correspond to different end positions or transmission lengths, and the end position of the first transmission is determined directly or indirectly based on the signal bandwidth.

[0124] Different center frequencies correspond to different end positions or transmission lengths, and the end position of the first transmission is determined directly or indirectly based on the center frequency. The aforementioned first indication information is used to explicitly or implicitly indicate the transmission length of the first transmission and whether the first transmission includes at least one of the following: a postamble. Furthermore, the aforementioned transmission length can be the total transmission length of the first transmission, or the transmission length of each transmission within the first transmission.

[0125] The end position of the first transmission can be determined directly or indirectly by the transmission length of the first transmission, and the end position of the first transmission can be determined directly or indirectly by whether the first transmission includes a postamble.

[0126] In some implementations, the first indication information may be information displayed and carried in the first transmission, or the first indication information may be carried in other transmissions.

[0127] For example, the first indication information is carried in at least one of the following:

[0128] The first transmission, the control information of the first transmission, and the Medium Access Control (MAC) information.

[0129] In some implementations, one first indication message indicates the transmission length of n transmissions including the first transmission, or m first indication messages indicate the transmission length of n transmissions including the first transmission, where m is a positive integer less than or equal to n, and n is a positive integer.

[0130] The aforementioned n transmissions can be n segmented transmissions of the first transmission, or n repeated transmissions.

[0131] The aforementioned n can be determined based on at least one of the aforementioned first information and first event, i.e., determining the last transmission, or the value of the aforementioned n can be agreed upon by the protocol or configured by the network-side device.

[0132] The aforementioned first indication information indicates the transmission length of n transmissions, including the first transmission, meaning that the transmission length of n transmissions is indicated by a first indication information, as shown in Figure 7, where n transmissions correspond to one first indication information.

[0133] The first indication information indicates the transmission length of n transmissions, including the first transmission, which can save transmission overhead.

[0134] The above m first indication information indicating the transmission length of n transmissions including the first transmission means that the number of first indication information is less than the number of transmissions. That is, some first indication information can indicate the transmission length of multiple transmissions, as shown in Figure 8, where first indication information #2 indicates the length of two transmissions.

[0135] The m first indication messages indicate the transmission length of n transmissions, including the first transmission. This allows for flexible indication of the transmission length, supporting more flexible transmission and improving transmission performance.

[0136] In some implementations, the granularity of the first indication information is associated with at least one of the following:

[0137] The total amount of data corresponding to the first transmission, the maximum amount of data allowed in the first transmission, and the type of the first transmission.

[0138] The total data volume corresponding to the first transmission mentioned above can refer to the total transmission volume of multiple transmissions of the first transmission, such as the total data volume of n transmissions.

[0139] The maximum amount of data allowed in the first transmission mentioned above can be the maximum amount of data allowed in a single transmission.

[0140] The aforementioned indicator granularity can be in bits or bytes, or different numbers of bits, such as 10-bit, 100-bit, 125-bit, and 200-bit indicator granularities.

[0141] In the above embodiments, the granularity of the first indication information can be determined based on the total data volume corresponding to the first transmission, the maximum data volume allowed by the first transmission, and the type of the first transmission, which easily saves the overhead of the first indication information. For example, coarse granularity can be used for large data volumes or transport blocks (TB), and fine granularity can be used for small data volumes or TBs. For example, fine granularity can be used for frequently used data ranges, and coarse granularity can be used for infrequently used data ranges. For example, the maximum TBS of R2D or D2R transmission is 1000 bits, but the TBS of most transmissions in R2D or D2R transmission is <400 bits. Therefore, fine granularity can be used in the <400 bit range, and coarse granularity can be used in the [400, 1000] bit range. For example, coarse granularity can be used for the inventory message 3 (msg3), and fine granularity can be used for other inventory message transmissions (e.g., msg0, msg1, or msg2). For example, coarse granularity can be used for inventory transmissions and fine granularity can be used for command transmissions, and vice versa.

[0142] In some implementations, the first indication information is used to indicate the transmission length of the first transmission among J transmission lengths, wherein the J transmission lengths are uniformly or non-uniformly distributed, and J is an integer greater than 1.

[0143] The J transmission lengths mentioned above are evenly divided, which can be understood as the difference between any two adjacent transmission lengths being the same. For example, they include transmission lengths of 125*1bit, 125*2bit, 125*3bit, 125*4bit, 125*5bit, 125*6bit, 125*7bit, and 125*8bit. The first indication information indicates the transmission length of the first transmission among these transmission lengths.

[0144] The non-uniform division of the J transmission lengths can be understood as a non-uniform distribution among the J transmission lengths, for example, including transmission lengths of 96bit, 156bit, 216bit, 276bit, 336bit, 400bit, 700bit, and 1000bit. The first indication information indicates the transmission length of the first transmission among these transmission lengths.

[0145] The flexibility of the first transmission can be improved by using the above-mentioned uniform or non-uniform distribution.

[0146] In some implementations, the first indication information is used for at least one of the following:

[0147] Indicate whether the first transmission includes a postamble;

[0148] The transmission length of the first transmission is indicated by a bitmap.

[0149] Alternatively, the first indication information is used for at least one of the following:

[0150] Indicate whether the first transmission includes a postamble;

[0151] The transmission length of the first transmission is indicated by code points.

[0152] The indication of whether the first transmission includes a postamble can be made by using a bitmap, code points, or other means.

[0153] In cases where the first transmission includes multiple transmissions, the above indication of whether the first transmission includes a postamble can be an indication of whether each transmission includes a postamble, and the above indication of transmission length can be an indication of the transmission length of each transmission. For example, as shown in Figure 9, the transmission lengths of different transmissions can differ, with only the last transmission including a postamble.

[0154] The above-mentioned bitmap method indicates the transmission length of the first transmission. Each bit of the bitmap corresponds to an index of the transmission length. For example, the bitmap contains X bits, and each bit position indicates a different TBS index. When the bit is set to 1, it indicates that the current TBS index is used, and when it is set to 0, it is not used. For example, if the bitmap contains 8 bits, the TBS indexes from high to low are 8, 7, 6, 5, 4, 3, 2, 1.

[0155] In this embodiment, indicating the transmission length of the first transmission using a bitmap can accurately indicate the transmission length of the first transmission.

[0156] The above-mentioned method of indicating the transmission length of the first transmission by code points can be used to indicate different transmission lengths for different code points. For example, if the maximum length of the first transmission is 1000 bits and the codepoint of the first indication information is n, then the transmission length of the first transmission = 2^n bits, and at least 10 bits are needed for indication. Alternatively, 3-bit codepoints from 000 to 111 can be used to indicate 8 TBS indices, where codepoint = 111 indicates the largest TBS = 1000 bits, and codepoints = 000 to 110 are used to indicate the TBS in the range of 0 to 1000 bits.

[0157] Indicating the transmission length of the first transmission using code points can save the bit overhead of the first indication information.

[0158] In some implementations, the first indication information includes a first bit string, which indicates the transmission length of the first transmission in the form of a bitmap, and the values ​​of all or part of the bits in the first bit string are used to indicate whether the first transmission includes a postamble; or,

[0159] The first indication information includes a second bit string, wherein a bitmap pattern in the second bit string simultaneously indicates the transmission length of the first transmission and whether the first transmission includes a postamble; or,

[0160] The first indication information includes a third bit string, wherein the first portion of the bits of the third bit string indicates the transmission length of the first transmission in a bitmap manner, and the second portion of the bits of the third bit string indicates whether the first transmission includes a postamble in a bitmap or codepoint manner; or,

[0161] The first indication information includes a fourth bit string, wherein the first portion of the bits in the fourth bit string indicates the transmission length of the first transmission in the form of code points, and the second portion of the bits in the fourth bit string indicates whether the first transmission includes a postamble in the form of code points or a bitmap; or,

[0162] The first indication information includes a fifth bit string, wherein a first portion of the code points in the fifth bit string indicates the transmission length of the first transmission, and a second portion of the code points in the fifth bit string indicates whether the first transmission includes a postamble.

[0163] The values ​​of all or some bits of the first bit string are used to indicate whether the first transmission includes a postamble. For example, if all or some bits of the first bit string are 1, it indicates that the first transmission includes a postamble; otherwise, the first transmission does not include a postamble. Alternatively, if all or some bits of the first bit string are 0, it indicates that the first transmission includes a postamble; otherwise, the first transmission does not include a postamble.

[0164] This allows the first bit string to be reused, thus saving the overhead of the first indication information.

[0165] A bitmap pattern in the second bit string above simultaneously indicates the transmission length of the first transmission and whether the first transmission includes a postamble. It can be all or part of the first indication information. The bitmap pattern can simultaneously indicate the transmission length of the first transmission and whether the first transmission includes a postamble. For example, bitmap pattern = 00000001 simultaneously indicates TBS index 1 and no postamble, and bitmap pattern = 00000010 simultaneously indicates TBS index 2 and the presence of a postamble.

[0166] This allows the second bit string to be reused, thus saving the overhead of the first indication information.

[0167] The second part of the third bit string indicates whether the first transmission includes a postamble by means of a bitmap or code points. The second part of the bit string can indicate whether the first transmission includes a postamble by means of a bitmap or code points alone. For example, the last or first bit of the third bit string indicates whether the first transmission includes a postamble, such as 1 indicating that it includes a postamble and 0 indicating that it does not.

[0168] This allows the second set of bits to indicate whether the first transmission includes a postamble, reducing complexity.

[0169] The first indication information includes a fourth bit string, wherein the first part of the bits in the fourth bit string indicates the transmission length of the first transmission in the form of code points, and the second part of the bits in the fourth bit string indicates whether the first transmission includes a postamble in the form of code points or a bitmap.

[0170] The second part of the fourth bit string indicates whether the first transmission includes a postamble by means of a bitmap or code points. The second part of the bit string can indicate whether the first transmission includes a postamble by means of a bitmap or code points alone. For example, the last or first bit of the fourth bit string indicates whether the first transmission includes a postamble, such as 1 indicating that it includes a postamble and 0 indicating that it does not.

[0171] This allows the second set of bits to indicate whether the first transmission includes a postamble, reducing complexity.

[0172] The second part of the code points in the aforementioned fifth bit string indicates whether the first transmission includes a postamble. This can be indicated by special code points in the fifth bit string, such as all 0s or all 1s indicating that the first transmission includes a postamble, and the remaining code points indicating the transmission length of the first transmission.

[0173] The fifth bit string indicates the transmission length and whether the first transmission includes a postamble. This allows the fifth bit string to be reused, thereby saving the overhead of the first indication information.

[0174] In some implementations, the first indication information is used to indicate the transmission length of multiple transmissions, including the first transmission, based on the same bit string using a bitmap, wherein the multiple transmissions correspond one-to-one with multiple bits in the bit string that take the value of the target value.

[0175] In the above bitmap, different bits can correspond to different transmissions. For example, bitmap pattern = 00000111 indicates three transmissions: the first transmission has TBS = 216, the second transmission has TBS = 156, and the third transmission has TBS = 96.

[0176] In this way, a single bitmap can indicate the transmission length for multiple transmissions, thus saving the overhead of the initial indication information.

[0177] Furthermore, the bitmap can also indicate the number of transmissions in the first transmission. For example, bitmap pattern = 00000111 indicates three transmissions.

[0178] As an optional implementation, the first event includes at least one of the following:

[0179] Does the first transmission include postamble?

[0180] Does the R value used to represent the number of repetitions in the first transmission indicate the end position?

[0181] Does the M value used to represent the number of chips in the first transmission indicate the end position?

[0182] Does the first transmission include an end position marker?

[0183] Does the first transmission include a non-end position marker?

[0184] In this case, whether the first transmission includes a postamble can directly determine the end position of the first transmission. For example, if the last transmission of the first transmission includes a postamble, then the end position can be directly determined based on the inclusion of a postamble.

[0185] Since the end position is determined by whether the first transmission includes a postamble, no additional information is needed, thus saving the overhead of the first transmission.

[0186] Here, R can represent the codewords being repeated R times over the time length of one information bit, and M can represent the number of chips in an OFDM symbol.

[0187] Whether the R value used to indicate the number of repetitions in the first transmission indicates the end position can be different before and after the transmission end position. For example, R=2 is used before the transmission end, and R=8 is used at the transmission end position. The end position can be directly determined by the above R value.

[0188] Since the end position is determined by the R value mentioned above, no additional information is needed, thus saving the overhead of the first transmission.

[0189] Whether the M value used to indicate the number of chips in the first transmission indicates the end position can be different before and after the transmission end position. For example, Manchester encoding is used before the transmission end, M=2, and Manchester encoding is used at the transmission end position, M=16. The end position can be directly determined by the above M value.

[0190] Since the end position is determined by the M value mentioned above, no additional information is needed, thus saving the overhead of the first transmission.

[0191] For n transmissions, whether the first transmission includes an end position mark can be determined by marking non-end positions in the first n-1 transmissions and marking the end position in the nth transmission, or by marking the end position only in the nth transmission and not marking it in the first n-1 transmissions. This can save the overhead of the first transmission.

[0192] For n transmissions, whether the first transmission includes a non-end position marker can be determined by marking the non-end position in the first n-1 transmissions and leaving the nth transmission unmarked, thus saving the overhead of the first transmission.

[0193] In some implementations, at least one of the aforementioned end position markers and non-end position markers is represented by a postamble or a sequence. For example, the marked end position marker can be represented by a special sequence including a postamble or all 0s or 1s, and the non-marked end position marker can be represented by a special sequence excluding a postamble or all 1s or 0s.

[0194] As an optional implementation, the indication used to indicate whether the first transmission includes a postamble is also used to indicate relevant parameters of the postamble.

[0195] The indication used to indicate whether the first transmission includes a postamble can be the first indication information mentioned above, or it can be indicated by the second indication information whether the first transmission includes a postamble.

[0196] The parameters related to the above postamble can include at least one of the following:

[0197] Sequence type, sequence index, generator polynomial, sequence length.

[0198] By specifying the relevant parameters mentioned above, the receiving end can be better able to detect postamble.

[0199] In some implementations, the aforementioned parameters may also be agreed upon by the protocol or pre-configured by the network-side device, and there is no limitation on this.

[0200] In this embodiment, the receiving end determines the end position of the first transmission based on at least one of first information and a first event. The first information is related information of the first transmission, and the first event is used to determine the end position. The receiving end performs at least one of the following based on the end position: determining the transmission length of the first transmission, and receiving the first transmission. Because the end position of the first transmission is determined based on at least one of the first information and the first event, and then the transmission length of the first transmission and / or the reception of the first transmission are determined based on the end position, demodulation errors at the receiving end can be avoided, thereby improving the receiving performance of the receiving terminal. This ensures that the receiving end can correctly demodulate the content carried in the first transmission.

[0201] Please refer to Figure 10, which is a flowchart of another transmission method provided in an embodiment of this application. As shown in Figure 10, it includes the following steps:

[0228] The first indication information includes a fourth bit string, wherein the first portion of the bits in the fourth bit string indicates the transmission length of the first transmission in the form of code points, and the second portion of the bits in the fourth bit string indicates whether the first transmission includes a postamble in the form of code points or a bitmap; or,

[0229] The first indication information includes a fifth bit string, wherein a first portion of the code points in the fifth bit string indicates the transmission length of the first transmission, and a second portion of the code points in the fifth bit string indicates whether the first transmission includes a postamble.

[0230] Optionally, the first indication information is used to indicate the transmission length of multiple transmissions, including the first transmission, based on the same bit string using a bitmap, wherein the multiple transmissions correspond one-to-one with multiple bits in the bit string that take the value of the target value.

[0239] It should be noted that this embodiment is an implementation of the transmitting end corresponding to the embodiment shown in Figure 6. For the specific implementation, please refer to the relevant description of the embodiment shown in Figure 6. In order to avoid repeated description, this embodiment will not be repeated.

[0240] The following uses an A-IoT device as an example to illustrate the method provided in the embodiments of this application:

[0241] Example 1:

[0242] This embodiment mainly describes determining the end position of R2D transmission or D2R transmission (i.e., the first position mentioned above), and the receiving end determines the end position in one of the following ways:

[0243] The first information indicating the end position is carried only through the first transmission (such as R2D control information); or

[0244] The end position is determined solely by the postamble of the first transmission; or

[0245] The end position is determined by the first information displayed in the first transmission (such as R2D control information) plus the postamble of the first transmission.

[0246] Furthermore, in this embodiment, TBS and transmission length (Length) can be interchanged, specifically including the following:

[0247] Determine whether the end position of the first transmission (such as R2D or D2R transmission) is determined based on the first information alone, the first event alone, or both the first information and the first event.

[0248] The first piece of information includes at least one of the following:

[0249] The first transmitted content is the message type, for example, command or inventory;

[0250] Does the first transmission carry CRC? Does the first transmission use repetition? Does the first transmission use FEC?

[0251] The first transmitted signal format information includes at least one of the following:

[0252] Encoding methods, e.g., FM0 (Miller coding), Manchester (no-line coding);

[0253] Modulation methods, e.g., OOK / ASK, MSK, FSK, BPSK.

[0254] In some implementations, the method for determining the end position is based on second information, wherein the second information is used for at least one of the following:

[0255] The instruction determines the end position based solely on the first piece of information;

[0256] The instruction determines the end position only based on the postamble;

[0257] The instruction contains both initial information and a postamble to determine the ending position.

[0258] In some implementations, the first event includes signal parameters that differ between the detection of the transmission end position and the detection of the transmission end position, such as:

[0259] The M value is different. For example, Manchester encoding is used before the end of transmission, M=2, and Manchester encoding is used at the end of transmission, M=16.

[0260] Different R values ​​are used; for example, R=2 is used before the end of transmission, and R=8 is used at the end of transmission.

[0261] In some embodiments, the first information mentioned above includes first indication information, which is used to indicate the transmission length (or TBS), wherein the first indication information is used to indicate the same transmission length (or TBS) n times; or, m first indication information indicates n transmission lengths (or TBS), where m≤n.

[0262] In some implementations, the first indication information is used to indicate the transmission length (or TBS) of at least two transmissions. The transmission length (or TBS) under the same indication information is the same, and the transmission length (or TBS) under different indication information is not limited to being the same.

[0263] In some implementations, the first indication information is used to indicate the transmission length (or TBS) of a single transmission, i.e., m = n.

[0264] In some implementations, when the transmission needs to be segmented, determining the end position of the transmission includes the following methods:

[0265] The marker indicates whether the transmission is at its end. For example, assuming n segmented transmissions, the non-end position is marked in the first n-1 transmissions, and the end position is marked in the nth transmission; or, the end position is marked only in the nth transmission, and the first n-1 transmissions are unmarked; or, the non-end position is marked in the first n-1 transmissions, and the nth transmission is unmarked. The end position can be marked using a postamble or a special sequence such as all 0s or 1s.

[0266] In some implementations, the first indication information can be carried by R2D control information and / or MAC information, or the first indication information can be R2D control information and / or MAC information. Wherein, if the target TBS is less than the indicated TBS, padding is required. The padding content can be 0, 1, or a sequence, and the end position is determined based on the padding sequence. If the target TBS is greater than the indicated TBS, TBS segmentation is required.

[0267] In some implementations, the manner in which the first indication information is indicated may include:

[0268] Explicit indication or only displaying the indication for small transmission lengths (also known as small payload size, such as indicating a transmission length less than 96 bits (e.g., transmission block (TB) ≤ 96 bits)); while for large transmission lengths (also known as large payload size (e.g., TB > 96 bits)), directly indicating the use of postamble or first event to determine the end position. That is, for large payload sizes, the transmission length is not indicated. When an indication is provided to use postamble or first event to determine the end position, it implicitly indicates TB > 100. The advantage of this is that it optimizes the case of small TB but not the case of large TB, avoiding the large indication overhead that would be introduced by the case of large TB.

[0269] Alternatively, the explicit indication may only indicate a large payload size (e.g., TB>96bit), while for a small payload size (e.g., TB≤96bit), the indication may directly indicate the use of postamble or the first event to determine the end position. When this indication is provided, it implicitly indicates that TB≤96bit.

[0270] In some implementations, the granularity of the transmission length (or TBS) indicated by the first indication information is related to the total data volume of the first transmission, the maximum allowed R2D or D2R transmission data volume in a single transmission, and the command type, for example:

[0271] Use coarse granularity for large data volumes or TB, and fine granularity for small data volumes or TB.

[0272] Use fine granularity for frequently used data ranges and coarse granularity for infrequently used data ranges. For example, the maximum message size of R2D / D2R is 1000 bits, but the TBS of most transmissions during R2D / D2R transmission is <400 bits. Therefore, fine granularity can be used in the <400 bit range and coarse granularity can be used in the [400, 1000] bit range.

[0273] Use coarse-grained msg3 for inventory count transmission, and fine-grained msg for other inventory count transmissions (e.g., msg0, msg1, msg2).

[0274] Use coarse granularity for inventory transfers and fine granularity for command commands, and vice versa.

[0275] In some implementations, the granularity of the transmission length (or TBS) indicated by the first indication information can be uniform or non-uniform. For example, there are 8 TBS indices, and a maximum of 1000 bits need to be indicated. A uniform indication means that the TBS indicated by each adjacent TBS index differs by 125 bits, while a non-uniform indication means that the TBS difference indicated by each adjacent TBS index does not need to be consistent.

[0276] In some implementations, the first indication information is indicated by a bitmap or codepoint.

[0277] The bitmap indication includes the following methods:

[0278] This only indicates the transmission length (or TBS). The bitmap contains X bits, each indicating a different TBS index. A bit set to 1 indicates that the current TBS index is used, and a bit set to 0 indicates that it is not used. Specifically, for example, the bitmap contains 8 bits, indicating TBS indices from high to low as 8, 7, 6, 5, 4, 3, 2, 1; or,

[0279] Simultaneously indicating the transmission length (or TBS) and postamble. There are three ways to indicate both simultaneously. The first way is: the bitmap contains X bits, each bit indicating a different TBS index. Setting the bit to 1 indicates using the current TBS index, and setting it to 0 indicates not using it. A specific bitmap is used to indicate the postamble; for example, if all X bits of the bitmap are 0 or all 1, it indicates the postamble.

[0280] Alternatively, in the second way, the bitmap pattern indicates both the TBS index and the postamble. For example, bitmap pattern = 00000001 indicates both TBS index 1 and the absence of a postamble, while bitmap pattern = 00000010 indicates both TBS index 2 and the presence of a postamble.

[0281] Alternatively, a third approach: the first / last bit of an X-bit bitmap indicates the presence of a postamble. For example, X = an 8-bit bitmap where the first 7 bits indicate the TBS and the last bit indicates the presence of a postamble.

[0282] Codepoint instructions include the following methods:

[0283] Only the Transmission Length (TBS) is indicated. For example, in R2D transmission, the maximum message size is 1000 bits, and the first indicated codepoint is n, then the TBS is 2^n bits, requiring at least 10 codepoints; or,

[0284] Eight TBS indices are indicated using 3-bit codepoints from 000 to 111, where codepoint 111 indicates the largest TBS (1000), and codepoints 000 to 110 indicate the TBS within the 0-1000 bit range. The TBS can be uniform or non-uniform.

[0285] It also indicates the transmission length (or TBS) and the postamble. The codepoint contains X bits, and a specific codepoint is used to indicate the postamble. For example, if all X bits of the codepoint are 0 or all X bits are 1, it indicates the postamble. The rest indicate the TBS index.

[0286] In some implementations, the indications used to indicate postamble include indicating whether it exists, or additionally, indicating postamble-related parameters, including but not limited to sequence type, sequence index, generator polynomial, and sequence length.

[0287] Example 2:

[0288] This embodiment mainly describes how different M or R values ​​are detected in the first event to determine the end position of the first transmission.

[0289] In the method for determining the end position of the first transmission based on the postamble, in the scenario of transmission segmentation, the end position of the first transmission is determined when the M value of the postamble is detected to be a specific value.

[0290] As shown in Figure 11, the first transmission (R2D or D2R transmission) is segmented into n segments. The postamble in the first n-1 segments uses M=2, and the postamble in the last segment uses M=16. When an M value differs from all previous M values, the current nth segment is determined as the end of the entire transmission. Alternatively, the first n-1 segments may use the M value specified by the protocol, while the last segment may use a non-protocol-specified M value (e.g., M=5), etc.

[0291] As shown in Figure 12, when the detected R value is a specific value, it is the end position of the first transmission (such as D2R transmission). For example, the transmission at the non-end position is R=2. When R=8 is detected, the current transmission is the end position.

[0292] Embodiment 3:

[0293] This embodiment mainly describes the impact on transmission timing.

[0294] In this embodiment, when it is determined according to the second information that the end position of the first transmission is determined only based on the first indication information, at least one of the following conditions is satisfied:

[0295] The first indication information determines the transmission length (also referred to as TBS) of at least one transmission;

[0296] In the case of multiple transmissions, a plurality of transmissions corresponding to the same first indication information have the same transmission length, and it is not limited that transmission lengths corresponding to different first indication information are necessarily the same;

[0297] Assuming that transmission is performed n times, determining the transmission end position through a marker includes at least one of the following:

[0298] Marking a non-end position in the first n-1 transmissions, and marking an end position in the n-th transmission;

[0299] Only the n-th transmission is marked with an end position, and the first n-1 transmissions have no marker;

[0300] Marking a non-end position in the first n-1 transmissions, and the n-th transmission has no marker;

[0301] When the length of the first transmission or a single transmission (also referred to as TBS) is inconsistent with the size of the target transmission length (also referred to as TBS), padding is required, and 0, 1, a sequence or the like can be padded.

[0302] In some embodiments, as shown in FIG. 7, the first indication information indicates n times of the same transmission length (also referred to as TBS), wherein the transmission length or TBS is X bits or bytes. In the i-th transmission (1≤i<n), a non-end marker is or is not marked, and in the n-th transmission, a transmission end marker is or is not marked. It should be noted that the first n-1 transmissions and the n-th transmission cannot both be unmarked.

[0303] In some embodiments, as shown in FIG. 8, m first indication information indicate n transmission lengths (also referred to as TBS), wherein m≤n. The i-th first indication information indicates at least the transmission length (also referred to as TBS) of one transmission.

[0304] In one scenario, a first indication indicates the transmission length (or TBS) of at least one transmission. The transmission length (or TBS) indicated by different first indications is not limited to being the same. The transmission length (or TBS) of multiple transmissions indicated by the same indication remains the same. For example, if the first indication #i indicates 1 transmission and the indicated transmission length (or TBS) is 16 bits, and the first indication #j indicates 3 transmissions and the indicated transmission length (or TBS) is 96 bits, and the length of all 3 transmissions is the same, 96 bits.

[0305] In special cases, each received first indication message indicates only the transmission length (or TBS) of a single transmission. The transmission length (or TBS) indicated by each first indication is not limited to the same value. For example, the first indication message #i indicates a transmission length of 16 bits, and the first indication message #j indicates a transmission length of 96 bits.

[0306] When the target transmission length (or TBS) does not match the indicated transmission length (or TBS):

[0307] If the target TBS is less than the indicated TBS, padding is required. The padding content can be 0, 1, or a sequence. The end position is determined based on the filled sequence.

[0308] If the target TBS is greater than the indicated TBS, then TBS segmentation is required.

[0309] When it is determined, based on the second information, that the end position of the transmission is determined solely based on the postamble, it may include at least one of the following:

[0310] Determine the postamble of at least one transmission;

[0311] The end position of the first transmission is determined by at least one of the sequence type, sequence index, generator polynomial, and sequence length. For example, the sequence type, sequence index, generator polynomial, and sequence length of the last transmission are different from those of the previous ones, as shown in Figure 13.

[0312] Among them, the sequence type, sequence index, generator polynomial, and sequence length are the relevant parameters of the postamble, such as different parameters corresponding to different ending positions.

[0313] When the transmission end is determined based on the second information and jointly by the transmission length (or TBS) and the postamble, at least one of the following is included:

[0314] The first indication information indicates the transmission length (or TBS) of X transmissions. Assuming a total of n transmissions, then 1≤X≤n-1. The end position of the nth transmission is determined according to the postamble, as shown in Figure 9.

[0315] Multiple transmissions corresponding to the same first indication information have the same transmission length, but the transmission lengths of transmissions corresponding to different first indication information are not limited to the same size.

[0316] Example 4:

[0317] This embodiment mainly describes the transmission length or TBS table.

[0318] The basic unit for transmission length (or TBS) indication includes bit-level or byte-level.

[0319] The end position of the first transmission is determined based on the transmission length (or TBS) and / or postamble, and the transmission length (or TBS) is determined based on the index. Therefore, a corresponding transmission length (or TBS) table needs to be designed. The following is an example of a TBS table.

[0320] In some implementations, the design specification for the maximum transmission length (also known as the maximum message size) of R2D and D2R transmissions is around 1000 bits. In the TBS table, 1000 bits can be used as the maximum transmission length.

[0321] Bitmap-based indication includes the following methods:

[0322] Bit-level: Assuming an 8-bit bitmap is used to indicate the TBS index, and considering the maximum message size of 1000 bits, it can be divided into two types: uniform indication or non-uniform indication.

[0323] Method a: Supports only TBS indicator or only postamble + uniform indicator:

[0324] In scenarios that only support TBS indication or only support postamble, a special bitmap pattern can be used to represent postamble, while other bitmap patterns indicate TBS, such as all 0s or all 1s indicating postamble. The uniform TBS indication is determined based on the max message size and the number of bits in the bitmap. For example, if the max message size = 1000 and there are a total of n bits in the bitmap, then the TBS indicated by adjacent TBS indices differs by 1000 / n, as shown in Table 2 below.

[0325] Table 2:

[0326] In another implementation, postamble uses the default configuration, that is, if a bitmap pattern of 00000001 to 10000000 is detected, the corresponding TBS is used; if not detected, the end position of R2D transmission is determined by postamble by default.

[0327] Method b, combining TBS indicator with postamble and uniform indicator, can be shown in Table 3 below:

[0328] Table 3:

[0329] In the context of joint indication, another scenario is that a specific bit in the bitmap indicates the existence of a postamble. For example, if the first bit / last bit is 0, there is no postamble; if it is 1, the postamble exists.

[0330] The first bit in Table 4 below indicates whether postamble is used.

[0331] Table 4:

[0332] Method c: In another implementation, TBS is variable. That is, in the two implementations above, the TBS based on the bitmap pattern is fixed each time. In another implementation, such as bitmap pattern = 00000111, it means three transmissions. The first transmission TBS = 125 * 3, the second transmission TBS = 125 * 2, and the third transmission TBS = 125 * 1.

[0333] All three implementation methods described above are uniform indicators. Considering that the most common transmission scenarios are between 96 and 400 bits, while 1000 bits are less common, we consider using fine granularity to further differentiate the data in the 96-400 bit range and coarse granularity in the >400 bit range.

[0334] Method d, which only supports TBS indication or only supports postamble + non-uniform indication, is shown in Table 5 below:

[0335] Table 5:

[0336] Method e, TBS indicator combined with postamble + non-uniform indicator, is shown in Table 6 below:

[0337] Table 6:

[0338] In the case of joint indication, another scenario is that a certain bit in the bitmap indicates whether the postamble exists. For example, if the first bit / last bit is 0, there is no postamble, and if it is 1, the postamble exists.

[0339] As shown in Table 7, the first bit is used to indicate whether postamble is used.

[0340] Table 7:

[0341] In method f, another implementation, the TBS is variable, as in method c above.

[0342] In the implementations of methods d and e, the TBS based on the bitmap pattern is fixed each time. In another embodiment, such as bitmap pattern = 00000111, it represents three transmissions: the first transmission TBS = 216, the second transmission TBS = 156, and the third transmission TBS = 96.

[0343] Byte-level: Its implementation is the same as bit-level, so I won't go into details, except that the unit of indication is changed from bit to byte.

[0344] Codepoint-based instructions:

[0345] Bit-level: The unit of TBS indicated is bit.

[0346] Method a: In one implementation, if the transmitted codepoint = n, then TBS = 2^n bits. Considering that the max message size = 1000 bits, at least 10 bits of indication are required.

[0347] Method b: In one implementation, it is assumed that the codepoint is 3 bits, indicating a total of 8 cases.

[0348] In scenarios where only TBS indication is supported, there are 8 different TBS indices corresponding to 8 different cases. In scenarios with non-uniform TBS, considering that <400 bits is the common transmission TB, a fine-grained approach is used in the <400-bit range, and a coarse-grained approach is used in the >400-bit range, as shown in Table 8 below:

[0349] Table 8:

[0350] When both TBS indicators and postambles are supported, a particular codepoint indicates whether postamble is used, while others are used to indicate the TBS index, as shown in Table 9 below:

[0351] Table 9:

[0352] Alternatively, the first or last bit of the codepoint indicates whether postamble is used, while the others are used to indicate the TBS index. As shown in Table 10 below, the first bit indicates whether postamble is used; if the first bit = 0, it is not used, and if the first bit = 1, it is used.

[0353] Table 10:

[0354] Byte-level: Indicates that the unit of TBS is bytes.

[0355] In one implementation, if the transmitted codepoint = n, then TBS = 8 * 2^n bits. Considering the max message size = 1000 bits, at least 7 bits are required for indication.

[0356] Other implementation methods are the same as bit-level, and will not be described in detail here, except that the unit of indication is changed from bit to byte.

[0357] It should be noted that the specific values ​​for TBS in all the tables above are merely examples and do not limit the technical solutions provided in the embodiments of this application.
