[0001] Cross-references to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 202510385266.0, filed on March 28, 2025, entitled "A method, apparatus, device, and storage medium for transmitting information," the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, specifically to a method, apparatus, device, and storage medium for transmitting information indication. Background Technology

[0004] A backscatter communication system consists of an excitation signal source and a signal reflection device. It typically comprises a reader and a reflective tag. The reader generates the radio frequency (RF) excitation signal, while the reflective tag reflects the RF signal. The reader sends an RF signal to the reflective tag, which receives the signal and reflects it back. By changing the load impedance of the reflective tag's antenna, information is modulated into the backscattered signal. Specifically, when the reflection coefficient is configured as the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured as the second reflection coefficient, the excitation signal is completely reflected; and when the reflection coefficient is configured as the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0005] The Physical Device-to-Reader Channel (PDRCH) transmits relevant information, such as the information bit length Tb, frequency shift factor R, and device-to-reader chip length (D2R), which can each have multiple values. Each value needs to be individually indicated to the device, resulting in high signaling overhead. Summary of the Invention

Attached Figure Description

[0020] To more clearly illustrate the technical solutions of the embodiments of this disclosure, the accompanying drawings used in the description of the embodiments or related technologies will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this disclosure. For those skilled in the art, other drawings can be obtained based on these drawings.

[0021] Figure 1 is a flowchart illustrating a method for indicating transmitted information according to an embodiment of this disclosure;

[0022] Figure 2 is a schematic diagram of a transmission information indication device provided in an embodiment of this disclosure;

[0023] Figure 3 is a schematic diagram of a device provided in an embodiment of this disclosure;

[0024] Figure 4 is a schematic diagram of a chip system provided in an embodiment of this disclosure. Detailed Implementation

[0025] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0026] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0027] To better understand the above-described objectives, features, and advantages of this disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the described embodiments are only some, not all, of the embodiments of this disclosure. The specific embodiments described herein are merely for explaining this disclosure and are not intended to limit it. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure are within the scope of protection of this disclosure.

[0028] It should be noted that in this article, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0029] When the Physical Device-to-Reader Channel (PDRCH) supports Frequency-Division Multiple Access (FDMA), carrier frequency shifting can be achieved through coding. Specifically, when the frequency shift factor R = 2, each information bit is modulated into two square wave periods using an XOR or XNOW operation. This square wave modulation achieves the frequency shift effect without changing the signal transmission bandwidth; only the carrier frequency is shifted.

[0030] For D2R (Device to Reader) signals transmitted in PDRCH, the relationship between the device to reader chip length, information bit length Tb, and frequency shift factor R is as follows: R = Tb / (2 * D2R chip length).

[0031] Tb can be the channel coding bit length. If channel coding is not supported, such as in forward error correction coding, then Tb corresponds to the information bit length. Accordingly, bit rate is the information bit rate after channel coding, and data rate is the information data rate before channel coding; the two are related as follows: bit rate = data rate / coding rate. When channel coding is not supported, bit rate = data rate.

[0032] The following problems currently exist:

[0033] Since Tb, R, and chip length each have multiple values, such as K1, K2, and K3 respectively, indicating them one by one would result in high overhead, i.e., the overhead bits are: log2(K1) + log2(K1) + log2(K1) bits.

[0034] At least one embodiment of this disclosure provides a method, apparatus, device, storage medium, and chip for indicating transmission information. The device obtains physical layer device-to-reader channel (PDRCH) transmission indication information and / or first information. The first information is at least one of the following: information carried by the physical layer reader-to-device channel (PRDCH), information agreed upon in the protocol, or pre-configured information. The device can determine PDRCH transmission-related information based on the PDRCH transmission indication information and / or the first information, thereby indicating different information of PDRCH transmission in the PDRCH transmission indication information and / or the first information, without needing to separately indicate different PDRCH transmission-related information to the device, thus reducing signaling overhead.

[0035] Figure 1 is a schematic flowchart of a transmission information indication method provided in an embodiment of this disclosure. The method is applied to a device. The device may be a reflective tag in a backscatter communication system or a terminal including a reflective tag (e.g., user equipment, environmental IoT device, A-IoT device, or IoT device).

[0036] As shown in Figure 1, the method for indicating transmitted information includes, but is not limited to, steps 101 and 102:

[0037] In step 101, physical layer device-to-reader channel (PDRCH) transmission indication information and / or first information are obtained. The first information is at least one of the following: information carried by the physical layer reader-to-device channel (PRDCH), information agreed upon by the protocol, or pre-configured information.

[0038] In this embodiment, the device can receive a PRDCH sent by the reader, which carries PDRCH transmission indication information and / or first information.

[0039] The PDRCH transmission indication information includes, but is not limited to, at least one of the following (i) to (iii):

[0040] (i) The PDRCH transmits one or more of the relevant information items in a predefined or preconfigured set. The relevant information items can be index values ​​in the set or position information in the set (e.g., position information represented in bitmap form).

[0041] (ii) The value of any one or more of the information transmitted by PDRCH.

[0042] (iii) The index value of any one or more of the information transmitted by PDRCH in a predefined or preconfigured table.

[0043] The first information includes, but is not limited to, at least one of the following (1) to (15):

[0044] (1) At least one table that pre-qualifies or pre-configures information related to PDRCH transmission.

[0045] (2) The relationship between any two or more items in the PDRCH transmission information.

[0046] (3) The message type carried in the PRDCH. For example, if the PRDCH carries the Msg0 message, the first information may include the message type of the Msg0 message.

[0047] (4) The type of PDRCH that is scheduled or indicated.

[0048] (5) A set of pre-defined or pre-configured device-to-reader chip lengths.

[0049] (6) A set of pre-defined or pre-configured frequency shift factors R.

[0050] (7) A set of pre-defined or pre-configured chip rates.

[0051] (8) A set of pre-defined or pre-configured data rates.

[0052] (9) A set of pre-defined or pre-configured information bit rates.

[0053] (10) A set of pre-defined or pre-configured information bit lengths.

[0054] (11) The PRDCH contains information related to the device ID.

[0055] (12) Random Access (RA) access type indication.

[0056] (13) Information related to the offset of the carrier wave (CW) in PDRCH transmission. This information includes at least one of the following: whether an offset occurs, the offset value, and the offset factor. When PDRCH supports Frequency Division Multiple Access (FDMA), carrier frequency shifting can be achieved through coding. For example, when the frequency shift factor R = 2, each information bit is modulated into two square wave periods using an XOR or XNOT operation. This square wave modulation achieves the frequency shift effect without changing the signal transmission bandwidth; only the carrier frequency is shifted.

[0057] (14) PDRCH uses relevant parameters of Frequency-Division Multiplexing (FDM).

[0058] (15) The PDRCH uses non-FDM (non-Frequency Division Multiplexing) parameters. The non-FDM parameters are any one of the following:

[0059] The information field of the frequency shift factor R-related indication information is either the default state or zero bits;

[0060] The frequency shift factor R has a default value;

[0061] The device-to-reader chip length (D2R chip length) is the same as the information bit length Tb.

[0062] The device-to-reader chip length (D2R) indicator field is set to the default value.

[0063] The Frequency Division Multiple Access (FDMA) indication information is explicitly zero;

[0064] The frequency shift factor R has a unique value.

[0065] In step 102, PDRCH transmission related information is determined based on PDRCH transmission indication information and / or first information.

[0066] The PDRCH transmission information includes, but is not limited to, at least one of the following (a) to (f):

[0067] (a) Device to Reader chip length (D2R chip length).

[0068] (b) Frequency shift factor R.

[0069] (c) Data rate.

[0070] (d) Chip rate.

[0071] (e) Information bit rate.

[0072] (f) Information bit length Tb.

[0073] As can be seen, in this embodiment, the device obtains the Physical Layer Device-to-Reader Channel (PDRCH) transmission indication information and / or first information. The first information is at least one of the information carried by the Physical Layer Reader-to-Device Channel (PRDCH), the information agreed upon in the protocol, or the pre-configured information. Based on the PDRCH transmission indication information and / or the first information, the device can determine the PDRCH transmission-related information and realize the indication of different information of PDRCH transmission in the PDRCH transmission indication information and / or the first information, without having to separately indicate different PDRCH transmission-related information to the device, thereby reducing signaling overhead.

[0074] In addition, in this embodiment, the PDRCH transmission indication information and / or the first information include a PDRCH transmission indication indicating FDM and / or a PDRCH transmission indication indicating non-FDM, and may also include a PDRCH transmission indication indicating multiple devices, or a PDRCH transmission indication indicating a single device, without any specific limitation.

[0075] In some embodiments, the PDRCH transmission indication information includes a first indication field and / or a second indication field.

[0076] The first indication field is used to indicate at least one item in the relevant information set of the first transmission parameter and / or the set index value of the relevant information set of the second transmission parameter; the second indication field is used to indicate at least one item in the relevant information set of the second transmission parameter. See Example 2 below for details regarding the content of the first and second indication fields.

[0077] Wherein, the first transmission parameter and / or the second transmission parameter includes at least one of the following (a) to (f):

[0078] (a) Device to Reader chip length (D2R chip length).

[0079] (b) Frequency shift factor R.

[0080] (c) Data rate.

[0081] (d) Chip rate.

[0082] (e) Information bit rate.

[0083] (f) Information bit length Tb.

[0084] The relevant information of the first transmission parameter and / or the relevant information of the second transmission parameter includes at least one of the following (1) to (4):

[0085] (1) Values ​​of transmission parameters.

[0086] (2) Index value corresponding to the transmission parameters.

[0087] (3) The maximum value of the transmission parameters.

[0088] (4) Minimum value of transmission parameters.

[0089] For example, if the first indicator field is not the default / non-default value and the second indicator field is the default or default value, the PDRCH-related transmission information is searched in the first table; if both indicator fields are not the default or non-default value, the PDRCH-related transmission information is searched in the second table.

[0090] It should be noted that the first indicator field and the second indicator field indicate independently of each other, or the first indicator field and the second indicator field indicate jointly.

[0091] In some embodiments, in step 102, based on the PDRCH transmission indication information and / or the first information, the PDRCH transmission related information is determined, including the following (1) or (2):

[0092] (1) If the physical layer reader to device channel PRDCH is the first PRDCH, then based on the PDRCH transmission indication information and / or the first information, determine the PDRCH transmission related information in the first table.

[0093] Whether a PRDCH is the first PRDCH can be determined based on the type of the PRDCH. A first PRDCH includes at least one of the following:

[0094] The first PRDCH includes either a paging message or a Msg0 message;

[0095] The first PRDCH carries the scheduling information of the PDRCH containing the Msg1 message;

[0096] The first PRDCH transmission indication or scheduling PDRCH supports frequency division multiple access transmission;

[0097] The first PDRCH transmission indicates or schedules a PDRCH transmission using at least one frequency shift factor;

[0098] The first PRDCH is used for multicast transmission; for example, the first PRDCH carries the device group ID.

[0099] The first PRDCH is used for broadcast transmission;

[0100] The first PDRCH transmission indication or scheduling PDRCH transmission supports the shifting of at least one carrier frequency point.

[0101] The first PDRCH transmission indication or scheduling PDRCH is based on contention-based access;

[0102] The first PRDCH transmission does not carry the device ID;

[0103] The first PRDCH transmission carries an access type indication for contention-based random access.

[0104] Therefore, a PRDCH can be identified as the first PRDCH if its type indicates at least one of the above. For example, a PRDCH carrying a Msg0 message or a paging message or a PRDCH that triggers random access is the first PRDCH, and a PRDCH carrying a Msg2 message is the second PRDCH.

[0105] (2) If the PDRCH is the second PDRCH, the relevant information for PDRCH transmission is determined in the second table based on the PDRCH transmission indication information and / or the first information.

[0106] Whether a PRDCH is a second PRDCH can be determined based on the type of the PRDCH. A second PRDCH includes at least one of the following:

[0107] The second PRDCH includes the Msg2 message;

[0108] The second PRDCH carries the scheduling information of the PDRCH containing the Msg3 message;

[0109] The second PRDCH transmission indication or scheduling PDRCH does not support frequency division multiple access transmission;

[0110] The second PDRCH transmission indicates or schedules a PDRCH transmission using a frequency shift factor;

[0111] The second PRDCH is used for unicast transmission;

[0112] The second PRDCH is used for multicast transmission; for example, the second PRDCH carries the device group ID.

[0113] The second PDRCH transmission indication or scheduling PDRCH transmission supports the shifting of a carrier frequency point to a specific frequency point or a specific offset.

[0114] The second PDRCH transmission indication or scheduling PDRCH is based on non-contention-based access;

[0115] The second PRDCH transmission carries one or more device IDs;

[0116] The second PRDCH transmission carries an access type indication for non-contention-based random access.

[0117] It should be noted that "contention-free random access (CFRA)" and "contention-free access (CFA)" as described in the embodiments of this application have the same meaning.

[0118] Therefore, as long as the type of PRDCH indicates at least one of the above, it can be determined that PRDCH is the second PRDCH.

[0119] The first table and the second table satisfy any of the following:

[0120] The first table and the second table are independent of each other;

[0121] The first and second tables are the same table;

[0122] The first table and the second table are two subsets of the same table;

[0123] The relationship between the first table and the second table is: subset and universal, or universal and subset.

[0124] Among them, the first table and the second table are transmission mapping tables, which are mapping tables between the relevant information sets of different transmission parameters and the set index values ​​and transmission parameter index values.

[0125] For example, the first table includes a set of information related to the transmission parameters and a set index value, wherein the transmission parameters include at least one of the following:

[0126] Device-to-reader chip length;

[0127] Frequency shift factor;

[0128] Information data rate;

[0129] Chip transmission rate;

[0130] Information bit rate;

[0131] Information bit length.

[0132] The relevant information of the transmission parameters includes at least one of the following:

[0133] The values ​​of the transmission parameters;

[0134] The index value corresponding to the transmission parameters;

[0135] The maximum value of the transmitted parameters;

[0136] Minimum value of transmission parameters.

[0137] In some embodiments, in step 102, based on the PDRCH transmission indication information and / or the first information, the PDRCH transmission related information is determined, including the following (1) or (2):

[0138] (1) If the physical layer reader to device channel PRDCH is the first PRDCH, then the PDRCH transmission related information is determined in the first table based on the set index value and / or the index value of the transmission parameters included in the PDRCH transmission indication information.

[0139] (2) If the PDRCH is the second PDRCH, the PDRCH transmission related information is determined in the second table based on the set index value and / or the index value of the transmission parameters included in the PDRCH transmission indication information.

[0140] In some embodiments, if the first table and the second table are the same table, then in step 102, based on the PDRCH transmission indication information and / or the first information, the PDRCH transmission related information is determined, including the following (1) or (2):

[0141] (1) If the physical layer reader to device channel PRDCH is the first PRDCH, then based on the set index value and / or the index value of the transmission parameters included in the PDRCH transmission indication information, determine the PDRCH transmission related information in the first row or a specific row of the segment corresponding to the set index value and / or the index value of the transmission parameters in the same table.

[0142] (2) If the PDRCH is the second PDRCH, then based on the set index value and / or the index value of the transmission parameter included in the PDRCH transmission indication information, determine the transmission-related information of the PDRCH in the corresponding row of the segment corresponding to the set index value and / or the index value of the transmission parameter in the same table.

[0143] The segments are sets of parameters with the same transmission parameter values ​​or the same set index values, such as sets of transmission parameters with the same data rate, the same information bit rate, or the same information bit length Tb.

[0144] In some embodiments, if the first indication field and the second indication field included in the PDRCH transmission indication information indicate each other independently, then in step 102, based on the PDRCH transmission indication information and / or the first information, the PDRCH transmission related information is determined, including the following (1) or (2):

[0145] (1) Based on the set index value indicated by the first indication field and / or the index value of the transmission parameter, determine the corresponding PDRCH transmission related information in the first table.

[0146] (2) Based on the index value of the transmission parameter indicated by the second indication field, determine the corresponding PDRCH transmission related information in the second table.

[0147] As can be seen, in this embodiment, if the first indication field and the second indication field included in the PDRCH transmission indication information indicate each other independently, the corresponding PDRCH transmission-related information is determined directly in the first table based on the set index value indicated by the first indication field and / or the index value of the transmission parameters. Similarly, the corresponding PDRCH transmission-related information is determined in the second table based on the index value of the transmission parameters indicated by the second indication field.

[0148] In some embodiments, step 102 involves determining PDRCH transmission-related information based on PDRCH transmission indication information and / or first information, including:

[0149] If the PDRCH transmission indication information includes: relevant information about chip length and / or relevant information about the third transmission parameter, then the value or range of the chip length and / or the value or range of the third transmission parameter for PDRCH transmission are determined based on the type of the physical layer reader to device channel PDRCH.

[0150] The third transmission parameter includes at least one of the following (1) to (8):

[0151] (1) Frequency shift factor R;

[0152] (2) Data rate;

[0153] (3) Information bit rate;

[0154] (4) Chip rate;

[0155] (5) Information bit length Tb;

[0156] (6) Transport Block Size (TBS);

[0157] (7) Modulation and Coding Scheme (MCS);

[0158] (8) Transmission time length.

[0159] In some embodiments, the relevant information about the chip length includes a first value or a first index value of the chip length. Based on the type of the physical layer reader-to-device channel (PRDCH), the value or range of the chip length transmitted via PDRCH and the value or range of the third transmission parameter are determined, including the following (1) or (2):

[0160] (1) If the type of PRDCH indicates the first PRDCH, then determine the value corresponding to the first value or the first index value as the maximum or minimum value of the chip length of the PDRCH transmission.

[0161] (2) If the type of PRDCH indicates the second PRDCH, then the chip length of the PDRCH transmission is determined to be either the first value or the value corresponding to the first index value.

[0162] In some embodiments, if the relevant information of the third transmission parameter includes a second value or a second index value of the frequency shift factor, then based on the type of the physical layer reader-to-device channel PRDCH, the value or range of the chip length of the PDRCH transmission and the value or range of the third transmission parameter are determined, including the following (1) or (2):

[0163] (1) If the type of PRDCH indicates the first PRDCH, then determine the value corresponding to the second value or the second index value as the maximum or minimum value of the frequency shift factor of the PDRCH transmission.

[0164] (2) If the type of PRDCH indicates the second PRDCH, then the value of the frequency shift factor for PDRCH transmission is determined to be either the second value or the value corresponding to the second index value.

[0165] In some embodiments, if the relevant information packet data rate, information bit rate, or information bit length of the third transmission parameter is used, then the value or range of the chip length of the PDRCH transmission and the value or range of the third transmission parameter are determined based on the type of the physical layer reader-to-device channel PDRCH, including the following (1) or (2):

[0166] (1) If the type of PRDCH indicates the first PRDCH, then the value of the frequency shift factor of the PDRCH transmission is determined to be less than or equal to the calculated value or greater than or equal to the calculated value. The calculated value is based on the relevant information of the data rate, information bit rate or information bit length, and chip length.

[0167] (2) If the type of PRDCH indicates a second PRDCH, the value of the frequency shift factor for PDRCH transmission is determined to be a calculated value, which is calculated based on the relevant information of data rate, information bit rate or information bit length, and chip length.

[0168] In some embodiments, the relevant information about the chip length includes a set of chip length values ​​or a set of index values. Based on the type of the physical layer reader-to-device channel (PRDCH), the values ​​or ranges of the chip length transmitted in the PDRCH and the values ​​or ranges of the third transmission parameter are determined, including the following (1) or (2):

[0169] (1) If the type of PRDCH indicates the first PRDCH, then the chip length of the PDRCH transmission is determined to be any value in the set of chip length values ​​or any value corresponding to any index value in the set of index values.

[0170] (2) If the type of PRDCH indicates the second PRDCH, then the chip length of the PDRCH transmission is determined to be either a preset value in the set of chip length values ​​or a value corresponding to a preset index value in the set of index values.

[0171] Example 1:

[0172] This embodiment describes that Msg1 and Msg3 messages use different transmission mapping tables. The transmission mapping table is a mapping table between the relevant information set of different transmission parameters and the set index value and the transmission parameter index value.

[0173] (1) Tables used for Msg1 messages

[0174] In this embodiment, the PRDCH received by the device can be the first PRDCH, wherein the first PRDCH carries the scheduling information of the PDRCH where the paging message or Msg1 message is located.

[0175] The device determines the information bit length Tb#i of the PDRCH containing the Msg1 message in the first table by using the index value i in the PDRCH transmission indication information carried by the first PDRCH. Here, Tb#i represents the information bit length corresponding to the index value i in the first table.

[0176] The frequency shift factor R transmitted by the device is any value from the set of R values ​​corresponding to Tb#i in the first table, where each Tb corresponds to a set of R values ​​that is either agreed upon by the protocol or pre-configured. Correspondingly, the device-to-reader chip length (D2R chip length) is the minimum transmission time unit of the PRDCH.

[0177] For example, the first table is the transmission mapping table 1 shown in Table 1, which is used for the Msg1 message. The index value i carried by the first PRDCH is 1, and the information bit length of the PDRCH containing the Msg1 message is determined to be Tb#1 in the transmission mapping table 1. The frequency shift factor R is any value in the set of R values ​​corresponding to Tb#1 in the transmission mapping table 1, for example, R = 2. Correspondingly, the D2R chip length is D2R chip length#1-2 in the transmission mapping table 1.

[0178] Table 1: Transmission Mapping Table

[0179] In this embodiment, when the indication field of the PDRCH transmission indication information carried by the PRDCH received by the device explicitly or implicitly indicates at least one of the following conditions, Msg1 does not support FDMA, or the PRDCH is a unicast indication, or the PDRCH is a non-contention transmission, or the PDRCH transmission does not shift the center frequency of the CW:

[0180] Case 1: The R value information field is in the default state.

[0181] Case 2: R value is the default value, such as: zero value, null value, NaN value, all 1 value.

[0182] Case 3: The chip length value is the same as the Tb length.

[0183] Case 4: The chip length indicator field is at its default value.

[0184] Case 5: The FDMA indication information is explicit, such as "1" for supported and "0" for not supported.

[0185] Scenario 6: The PRDCH carries a device ID.

[0186] Case 7: RA type indication, such as: "1" for contention-based RA (CBRA), "0" for non-contention-based RA (CFRA).

[0187] Case 8: The R value is unique.

[0188] The above content applies to all methods in this solution, and will not be elaborated further below.

[0189] (2) Tables used for Msg3 messages

[0190] In this embodiment, the PRDCH received by the device can be a second PRDCH, wherein the second PRDCH carries the scheduling information of the PDRCH where the Msg3 message is located.

[0191] The device uses the index value i in the PDRCH transmission indication information carried by the second PDRCH to determine the information bit length Tb#i of the PDRCH where the Msg3 message is located in the second table, where Tb#i represents the information bit length corresponding to the index value i in the second table. The set of frequency shift factor R values ​​corresponding to each Tb is either agreed upon by the protocol or pre-configured.

[0192] The frequency shift factor R transmitted by the device is the R value corresponding to index i in the second table. The device-to-reader chip length (D2R chip length) is the D2R chip length corresponding to index i in the second table.

[0193] For example, the second table is the transport mapping table 2 shown in Table 2. Transport mapping table 2 is used for the Msg3 message, and this table is pre-configured or pre-defined by the protocol. The index value i carried by the second PRDCH is 1-2, and the information bit length of the PDRCH containing the Msg3 message is determined to be Tb#1 in transport mapping table 2. The frequency shift factor R is the R value corresponding to the index value i (i is 1-2) in transport mapping table 2, and R = 2. The D2R chip length is the D2R chip length corresponding to the index value i (i is 1-2) in transport mapping table 2, that is, D2R chip length#1-2.

[0194] Table 2 Transmission Mapping Table 2

[0195] In some embodiments, the transmission mapping table 1 or the transmission mapping table 2 may also be Table 3 or Table 4 as shown below. In Table 3 and Table 4, some columns in columns 2 to 4 may be omitted.

[0196] Table 3. A Transmission Mapping Table

[0197] Table 4. Another type of transmission mapping table

[0198] The set of R values ​​#i can be: {R value #1, R ​​value #2, ..., R value #N}, where R value #1 can be the minimum / maximum value. Since D2R chip length * 2 * R = Tb, the minimum / maximum R value corresponds to the minimum / maximum Tb. The number of R values ​​in the set corresponding to different D2R chip lengths can be different.

[0199] Example 2:

[0200] This embodiment describes the indication fields included in the PDRCH transmission indication information. For example, the PDRCH transmission indication information includes a first indication field and / or a second indication field. The first indication field is used to indicate at least one item in the relevant information set of the first transmission parameter and / or the set index value of the relevant information set of the second transmission parameter; the second indication field is used to indicate at least one item in the relevant information set of the second transmission parameter.

[0201] Wherein, the first transmission parameter and / or the second transmission parameter includes at least one of the following (a) to (f):

[0202] (a) Device to Reader chip length (D2R chip length).

[0203] (b) Frequency shift factor R.

[0204] (c) Data rate.

[0205] (d) Chip rate.

[0206] (e) Information bit rate.

[0207] (f) Information bit length Tb.

[0208] The relevant information of the first transmission parameter and / or the relevant information of the second transmission parameter includes at least one of the following (1) to (4):

[0209] (1) Values ​​of transmission parameters.

[0210] (2) Index value corresponding to the transmission parameters.

[0211] (3) The maximum value of the transmission parameters.

[0212] (4) Minimum value of transmission parameters.

[0213] For example, the first and second indicator fields include at least one of the following options one through four:

[0214] Option 1:

[0215] The D2R transmission information indication field is the first indication field, and the chip length indication field is the second indication field. That is, the second indication field is used to indicate the relevant information of the second transmission parameter (i.e., D2R chip length) (e.g., the value of D2R chip length, the index value corresponding to D2R chip length, the maximum value of D2R chip length, and / or the minimum value of D2R chip length).

[0216] Option 2:

[0217] Among them, the D2R transmission information indication field is the first indication field, and the R value indication field is the second indication field.

[0218] Option 3:

[0219] Among them, the D2R transmission information indication field is the first indication field, and the R value indication field and the Chip length indication field are two subfields of the second indication field.

[0220] Option 4:

[0221] Among them, D2R transmission information indication field 1 is the first indication field, and D2R transmission information indication field 2 is the second indication field.

[0222] Taking option four as an example, Table 5 is a PDRCH transmission indication information table.

[0223] Table 5. One type of PDRCH transmission indication information table

[0224] It should be noted that the "Meaning" column in Table 3 is for illustrative purposes only; in actual transmission, the "Meaning" column is not present in Table 3.

[0225] When PDRCH transmission supports FDMA, if the frequency shift factor R sent by the device is any one of the values ​​in Table 1 or Table 2, the corresponding D2R chip length is the minimum transmission time unit of PDRCH, satisfying R = Tb / (2 * D2R chip length).

[0226] Example 1: The R value indicator field consists of 3 bits: "000" indicates that it is not FDM or the chip length is equal to the Tb length; "001 to 110" indicate a maximum of 6 predefined or preconfigured R values; and "111" indicates that the R value is randomly selected from the 6 predefined or preconfigured R values.

[0227] Example 2: The R value indicator field is 8 bits: "0000 0000" indicates non-FDM or the chip length is equal to the Tb length; "XXXX XXXX" performs bit mapping, meaning that the device can use the corresponding R value from 8 predefined or preconfigured R sets for non-zero bits. When there are multiple non-zero bits, the device can randomly select the R value corresponding to multiple non-zero bits.

[0228] It should be noted that different sets of R can be used for each data rate. For example, 8 R values ​​can be used for low data rates and 4 R values ​​can be used for high data rates. The R values ​​can also be equivalent to chip length.

[0229] Taking option four as an example, Table 6 is another PDRCH transmission indication information table.

[0230] Table 6. Another type of PDRCH transmission indication information table

[0231] The preset values ​​can be found in Examples 1 and 2 above, and will not be repeated here.

[0232] Example 3:

[0233] This embodiment describes that Msg1 and Msg3 messages use a common transport mapping table.

[0234] In this embodiment, the first table corresponding to the Msg1 message is a subset or the entirety of the second table corresponding to the Msg3 message. The first table and the second table can be merged into a common transport mapping table used by the Msg1 message and the Msg3 message. This table is a protocol and limitation or pre-configured table, as shown in Table 7 below.

[0235] Table 7 Transmission Mapping Table

[0236] Transmission-related information for Msg1 and Msg3 messages can be found in some or all of Table 7. For example, based on the message type carried by the PDRCH or the PDRCH transmission indication information, transmission-related information can be found in Table 7, including the following methods one and / or two:

[0237] Method 1:

[0238] The transmission information for Msg1 messages can be found in parts of Table 7, such as the first N rows of Table 7; the transmission information for Msg3 messages can be found in all of Table 7.

[0239] Method 2:

[0240] The first row of each segment in Table 7 identifies the transmission-related information of the PDRCH transmitted using non-FDM (non-Frequency Division Multiplexing) methods.

[0241] In any row of each segment included in Table 7, determine the transmission-related information of the PDRCH transmitted using Frequency Division Multiplexing (FDM).

[0242] In Table 7, each segment refers to a set of transmission parameters with the same values, such as a set of transmission parameters with the same data rate or the same information bit length Tb.

[0243] As can be seen, the transmission-related information of PDRCH transmitted using Frequency Division Multiplexing (FDM) is determined from the transmission mapping tables shown in Table 8 or Table 9 below.

[0244] Table 8. A Transmission Mapping Table

[0245] Table 9. Another type of transmission mapping table

[0246] Each parameter set indicates a corresponding Tb or data rate or information bit rate.

[0247] Example 4:

[0248] This embodiment describes PDRCH transmission indication information including D2R chip length indication information and frequency shift factor R indication information, i.e., {chip length indication information, R indication information}. The D2R chip length can be one item from a predefined or preconfigured set of chip lengths, and the frequency shift factor R can also be one or more items from a predefined or preconfigured set of R values.

[0249] For Msg1 and / or Msg3 messages sent using non-FDMA methods, PRDCH carries indication information of the D2R chip length, such as chip length index value 1 (CL_index#1) or chip length value 1 (CL_value#1), where D2R chip length is equal to Tb. The R value can be either a default or a default value, where the default value is at least one of the following: zero, null, NaN, or all 1s.

[0250] For Msg1 and / or Msg3 messages transmitted using FDMA, the transmission information of Msg1 and / or Msg3 messages can be determined using at least one of the following methods from Method 1 to Method 4:

[0251] Method 1: Determine the R value based on the message type carried by the PRDCH.

[0252] The frequency shift factor R of D2R is indicated by either R index value 1 (R_index#1) or R value (R_value#1).

[0253] If the message type indicates a Msg0 message, different devices can choose any value of R from those less than or equal to R_index#1 (or R_value#1). That is, the value corresponding to R_index#1 or R_value#1 is the largest R value. It should be noted that the information bit length Tb is different for different devices, where Tb = 2 * R * chip length.

[0254] If the message type indicates Msg2, that is, the PRDCH used to schedule Msg3, then the device uses the value corresponding to R_index#1 or R_value#1.

[0255] Additionally, the D2R chip length indication information is either chip length index value 1 (CL_index#1) or chip length value 1 (CL_value#1). The device determines the chip length to be used as the value corresponding to CL_index#1 or CL_value#1.

[0256] Method 2: Determine whether the chip length value is the actual chip length or the information bit length Tb based on the message type carried by the PRDCH.

[0257] The D2R chip length indication information is: chip length index value 1 (CL_index#1) or chip length value 1 (CL_value#1). The D2R frequency shift factor R indication information is: R index value 1 (R_index#1) or R value (R_value#1).

[0258] If the message type indicates a Msg0 message, then the D2R chip length indication information is the maximum or minimum chip length, i.e., Tb = chip length. Based on the chip length, different devices can arbitrarily choose the R value within the range less than or equal to the value corresponding to R_index#1 (or R_value#1). It should be noted that the actual chip length = indicated chip length / (2 * R).

[0259] If the message type indicates a Msg2 message, the device determines the R value to be either the value corresponding to R_index#1 or R_value#1. The chip length of D2R is either the value corresponding to CL_index#1 or CL_value#1.

[0260] Method 3: Based on the RA access type indication information, determine whether the R value is a specific value, a maximum value, or a minimum value. If the RA access type indication information is "0", indicating a non-contention RA, then R is a specific value and can be used for the transmission indication of the PDRCH where the Msg3 message is located; if the RA access type indication information is "1", indicating contention access, then the R value is the maximum or minimum value and can be used for the transmission indication of the PDRCH where the Msg1 message is located.

[0261] Method 4: Based on the RA access type indication information, determine whether the D2R chip length is a specific value, maximum value, or minimum value. If the RA access type indication information is "0", indicating a non-contention RA, then the D2R chip length is a specific value, which can be used for the transmission indication of the PDRCH where the Msg3 message is located; if the RA access type indication information is "1", indicating a contention RA, then the D2R chip length is the maximum or minimum value, which can be used for the transmission indication of the PDRCH where the Msg1 message is located.

[0262] Example 5:

[0263] This embodiment describes PDRCH transmission indication information including D2R chip length indication information and D2R information transmission rate related information, namely {chip length indication information, data rate / Tb indication information}. The D2R chip length can be one or more items from a predefined or preconfigured set of chip lengths, and the data rate / Tb can also be one or more items from a predefined or preconfigured set of data rate / Tb. The device can calculate the frequency shift factor R using the following formula: R = Tb / (2 * D2R chip length), where Tb = 1 / data rate.

[0264] For Msg0 and / or Msg3 messages transmitted in non-FDM mode, the PRDCH carries indication information for D2R chip length and / or data rate / Tb. The D2R chip length indication information is, for example, chip length index value 1 (CL_index#1) or chip length value 1 (CL_value#1). The data rate / Tb indication information is, for example, data rate index value 1 (DR_index#1) or data rate value (DR_value#1), where chip length equals Tb. Both the chip length indication field and the data rate / Tb indication field can have one field set to a default value or a default value, where the default value is at least one of the following: zero, null, NaN, or all 1s.

[0265] For Msg0 and / or Msg3 messages transmitted in FDM mode, the PRDCH carries an indication of the D2R chip length (e.g., CL_index#1 or CL_value#1) and / or an indication of the data rate / Tb (e.g., DR_index#1 or DR_value#1). The transmission-related information for Msg0 and Msg3 messages can be determined using either method one or method two:

[0266] Method 1: The PDRCH information data rate or information bit length Tb is determined based on the message type and the D2R chip length indication information, specifically: the maximum / minimum transmission time unit, or the actual transmission time unit.

[0267] If the message type indicates Msg0, the device transmits Msg1 messages according to the data rate / Tb indication. The D2R chip length indication, such as CL_index#1 or CL_value#1, is used for transmission in the minimum transmission time unit. The frequency shift factor R corresponding to CL_index#1 or CL_value#1 is: R_value = Tb / (2 * D2R chip length). Different devices can randomly select an R value between 1 and R_value for PDRCH transmission, or they can select an R value no higher than R_value from a pre-defined or pre-configured set of R values. For example:

[0268] If the message type indicates Msg2, the device will transmit Msg3 messages according to the data rate / Tb indication information, and the D2R chip length indication information, such as CL_index#1 or CL_value#1, will be transmitted in the transmission time unit.

[0269] Method 2: The D2R chip length indication information is a set of multiple chip lengths. The first value is used to indicate the transmission information of a default device, such as the transmission indication of a Msg3 message. Different devices using FDM can randomly select a chip length from the set of chip lengths for D2R data transmission. For example:

[0270] Example 6:

[0271] This embodiment describes the PRDCH carrying indication information {chip length, TBS, MCS}.

[0272] The PRDCH carries D2R chip length indication information and D2R information transmission rate / Tb related information, i.e. {chip length indication information, data rate / Tb indication information related information}. The D2R chip length can be one or more items from a predefined or preconfigured set of chip lengths, and the data rate / Tb can be the information bit length Tb and / or the information bit transmission rate, which can be indirectly obtained.

[0273] For example, the information bit length can be determined based on the PDRCH's TBS indicator, MCS level, and Cyclic Redundancy Check (CRC) length. Specifically, the TBS indicator determines the PDRCH transmission time length (TTI), in units of OFDM symbols, time slots, milliseconds, etc., and / or the information data volume (K bits). The MCS indicates the modulation order (Q) used in the PDRCH transmission, such as BPSK / OOK (modulation order 1), QPSK (modulation order 2), and so on, as well as the channel coding / forward error correction (FEC) coding rate, such as 1 / 3, 1 / 2, 1, where a code rate of 1 indicates no channel coding. The information bit length is: Tb = TTI / ((K / Q + CRC bit length) / coding rate), where the CRC bit length is protocol-defined, or the D2R information transmission rate = K / TTI.

[0274] Note: The relationship between TTI, information data volume and at least two of the MCS indicated by TBS above can be a TBS table agreed upon in the protocol or a pre-configured relationship.

[0275] For example, when the modulation method is BPSK or OOK modulation, without CRC, Tb = TTI / (K / coding rate), and / or D2R information transmission rate = K / TTI.

[0276] The device receives the D2R chip length indication information and D2R information transmission rate / Tb related information carried by the PRDCH. If Tb = chip length is calculated, the D2R transmission will not perform CW frequency shift; otherwise, the D2R transmission can perform CW frequency shift. The frequency shift factor is related to R = Tb / (2*chip length).

[0277] Example 7:

[0278] This embodiment describes how PDRCH transmission-related information is indicated in different types of PDRCH.

[0279] The types of PDRCHs received by the device differ, and the way they indicate the transmission-related information of the scheduled PDRCHs differs, as shown in (1) and (2) below:

[0280] (1) For unicast / multicast scheduling PRDCH, it carries D2R chip length indication information and corresponding frequency shift factor R, or it only carries D2R chip length indication information, without frequency shift factor or frequency shift factor is the default value, such as 0.

[0281] The device can obtain its bit length Tb using the chip length indication information it carries and the corresponding frequency shift factor R, i.e., Tb = 2 * R * chip length. Alternatively, the device can obtain its bit length as chip length based on R being 0.

[0282] Here, the PRDCH for unicast scheduling can be determined based on at least one of the following methods: the PRDCH carries a device ID, or the PRDCH carries the message Msg2, or the PRDCH carries the message Msg0 or paging and indicates a device ID.

[0283] For multicast scheduling, the PRDCH can carry multiple device information, such as device ID. Each device can obtain the corresponding D2R chip length indication information and the corresponding frequency shift factor R based on the device information, in the same way as unicast scheduling.

[0284] (2) For broadcast / multicast scheduling, the PRDCH carries D2R chip length indication information and information related to the maximum (minimum) frequency shift factor Rmax (Rmin) value. The device determines the corresponding D2R chip length and the maximum / minimum frequency shift factor R based on the D2R chip length indication information and the information related to the maximum / minimum frequency shift factor R.

[0285] The device randomly selects a frequency shift factor R that is less than (greater than) Rmax (Rmin) for PDRCH transmission at a specific chip length, where the bit length is Tb, i.e.: Tb_min (Tb_max) = 2 * Rmax (Rmin) * chip length.

[0286] For broadcast / multicast scheduling, the PRDCH carries D2R chip length indication information and information related to multiple frequency shift factors R (R set). The device determines the corresponding D2R chip length based on the D2R chip length indication information. The device determines multiple bit lengths Tb based on the multiple frequency shift factors R (R set).

[0287] or,

[0288] For broadcast / multicast scheduled PDRCHs, the PDRCH carries D2R chip length indication information and information related to the maximum (minimum) frequency shift factor Rmax (Rmin) value. The D2R chip length indication information indicates the maximum or minimum chip length used by the device to transmit the PDRCH. The device determines the maximum or minimum D2R chip length based on the D2R chip length indication information. Taking the minimum D2R chip length as an example (chip length_min), the information length transmitted by the device is: Tb = 2 * Rmax (Rmin) * chip length_min. The device can randomly select the R value and the corresponding chip length with a fixed Tb.

[0289] The PRDCH for broadcast scheduling can be determined based on at least one of the following methods: the PRDCH does not carry a device ID, or the PRDCH carries a message type of Msg0 or paging.

[0290] The PRDCH for multicast scheduling can be determined based on at least one of the following methods: the PRDCH carries device group-related information, such as the device group ID.

[0291] Example 8:

[0292] This embodiment describes PDRCH transmission indication information including D2R bit length indication information and frequency shift factor R indication information, i.e., {bit length indication information, R indication information}. The D2R bit length can be one item from a predefined or preconfigured set of bit lengths, and the frequency shift factor R can also be one or more items from a predefined or preconfigured set of Rs.

[0293] For Msg1 and / or Msg3 messages transmitted using non-FDMA methods, the PRDCH carries an indication of the D2R bit length, such as a bit length index value of 1 (Tb_index#1) or a bit length value of 1 (Tb_value#1), where the D2R bit length is equal to Tb. The R value can be either a default or a default value, where the default value is at least one of the following: zero, null, NaN, or all 1s.

[0294] For Msg1 and / or Msg3 messages transmitted using FDMA, the transmission information of Msg1 and / or Msg3 messages can be determined using at least one of the following methods from Method 1 to Method 4:

[0295] Method 1: Determine the R value based on the message type carried by the PRDCH.

[0296] The frequency shift factor R of D2R is indicated by either R index value 1 (R_index#1) or R value (R_value#1).

[0297] If the message type indicates a Msg0 message, different devices can choose any value of R from those less than or equal to R_index#1 (or R_value#1). That is, the value corresponding to R_index#1 or R_value#1 is the largest R value. It should be noted that the chip length differs between different devices; chip length = Tb / (2*R).

[0298] If the message type indicates Msg2, that is, the PRDCH used to schedule Msg3, then the device uses the value corresponding to R_index#1 or R_value#1.

[0299] Additionally, the D2R bit length indication information is either bit length index value 1 (Tb_index#1) or bit length value 1 (Tb_value#1). The device determines the bit length to be used and the chip length determined by R.

[0300] Method 2: Based on the RA access type indication information, determine whether the R value is a specific value, a maximum value, or a minimum value. If the RA access type indication information is "0", indicating a non-contention RA, then R is a specific value and can be used for the transmission indication of the PDRCH where the Msg3 message is located; if the RA access type indication information is "1", indicating contention access, then the R value is the maximum or minimum value and can be used for the transmission indication of the PDRCH where the Msg1 message is located.
