[0114] Figure 1A This is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0115] like Figure 1A As shown, the communication system 100 includes a terminal 101 and a network device 102.

[0116] In some embodiments, terminal 101 may include IoT devices, narrowband Internet of Things (NB-IoT) devices, machine type communication (MTC) devices, reduced capability (RedCap) devices, environmental Internet of Things (A-IoT) devices, etc.

[0117] For example, in this embodiment of the disclosure, terminal 101 may be an A-IoT device, or referred to as an A-IoT terminal, tag, environmental energy-based device, passive device, passive terminal or passive node, etc., and is simply referred to as a terminal or device.

[0118] For example, an A-IoT device is a device that operates powered by ambient energy harvested from radio waves, light, motion, heat, or other available environmental energy sources. An A-IoT device has little or no electrical power supply. Depending on whether an A-IoT device has energy storage capabilities and the ability to independently generate signals, A-IoT devices may include the following three types: Device 1, Device 2a, and Device 2b, but the possibility of adding new A-IoT device types in the future is not excluded. Among them:

[0119] Device 1 supports at least one of the following: it has a small energy storage capacity, no ability to independently generate or amplify signals, transmits signals via backscatter, has a peak power consumption of approximately 1 microwatt (μW), an initial sampling frequency offset (SFO) of up to 10 x ppm (x can be 4 or 5), and no downlink or uplink signal amplification capabilities. The uplink transmission of this device is achieved through backscattering on an externally provided carrier.

[0120] Device 2a supports at least one of the following: it has a large energy storage capacity, no ability to generate signals independently, transmits signals by backscattering, can use stored energy to amplify reflected signals, its peak power consumption does not exceed several hundred μW, its SFO is as high as 10x ppm (x can be 3, 4 or 5), and has the ability to amplify downlink signals and / or uplink signals. The uplink transmission of this device is achieved by backscattering on an externally provided carrier.

[0121] Device 2b supports at least one of the following: it has a large energy storage capacity, the ability to generate signals independently, uses radio frequency devices for signal transmission, its peak power consumption does not exceed several hundred μW, its SFO is up to 10x ppm (x can be 3, 4 or 5), and has the ability to amplify downlink signals and / or uplink signals. The uplink transmission of this device is implemented by the radio frequency devices inside the device.

[0122] In some embodiments, network device 102 may include one or more network-side nodes or devices, or nodes or devices that assist in implementing network-side functions.

[0123] For example, network device 102 may include at least one of access network device and core network device. The access network device may be, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation evolved Node B (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0124] In some examples, access network devices may include an A-IoT RAN for environmental IoT, or may include a reader.

[0125] In some examples, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0126] In some examples, access network equipment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. The CU-DU structure can separate the protocol layer of the access network equipment. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU. However, this is not the only example.

[0127] In some examples, a core network device can be a single device comprising one or more network elements, or it can be multiple devices or groups of devices, each comprising all or part of one or more network elements. Network elements can be virtual or physical. The core network includes, for example, at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0128] In some examples, core network equipment may include a core network for the Internet of Things in the Environment (A-IOT CN).

[0129] In some examples, core network equipment includes network elements with specific functions, such as Access Management Function (AMF) and Service Management Function (SMF).

[0130] For example, network device 102 may include a reader, or may include user equipment (UE) acting as a reader or repeater in A-IoT technology. The UE may include, for example, at least one of the following: mobile phone, wearable device, IoT device, car with communication capabilities, smart car, tablet, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home, but is not limited thereto.

[0132] In some embodiments, such as Figure 1BThe topology 1 shown in the diagram involves a direct bidirectional connection between terminal 101 (e.g., an A-IoT device) and network device 102 (e.g., a base station, BS). The communication between the A-IoT device and the base station includes data and signaling. Topology 1 also includes another possible scenario: the downlink and corresponding uplink base stations for the same service communication are different base stations. For example, base station 1 sends downlink information to the A-IoT device, and the A-IoT device sends uplink information to base station 2. In this case, the downlink and corresponding uplink base stations for the same service communication are different base stations.

[0133] In some embodiments, such as Figure 1C In Topology 2, as shown, terminal 101, such as an A-IoT device, and network device 102, such as a base station, communicate via an intermediate node 103. The A-IoT device communicates bidirectionally with the intermediate node 103, and the intermediate node 103 communicates bidirectionally with the base station using cellular communication. The intermediate node 103 can be considered a relay between the A-IoT device and the base station. The intermediate node 103 can be, for example, an Integrated Access Backhaul (IAB) node, a UE, or a repeater. The intermediate node must support the ability to communicate with the A-IoT device. The intermediate node 103 bidirectionally transmits data and signaling between the base station and the A-IoT device to complete the communication.

[0134] In some embodiments, the design goals of A-IoT include device power consumption, device complexity, coverage performance, user data rate, latency, and mobility speed.

[0135] In some embodiments, A-IoT deployment scenarios may include the following:

[0136] Deployment Scenario 1: A-IoT devices are indoors, and base stations are indoors.

[0137] Deployment Scenario 2: A-IoT devices are indoors, and base stations are outdoors.

[0138] Deployment Scenario 3: The A-IoT device is indoors, and the reader / writer is the UE.

[0139] Deployment Scenario 4: A-IoT devices are outdoors, and base stations are outdoors.

[0140] Deployment Scenario 5: The A-IoT device is outdoors, and the reader / writer is the UE.

[0141] In some embodiments, the links and channels of the A-IoT physical layer may include the following:

[0142] Reader-to-device (R2D) corresponds to the physical channel: Physical Reader to Device Channel (PRDCH).

[0143] Device-to-reader (D2R) corresponds to the physical channel: Physical Device to Reader Channel (PDRCH).

[0144] Carrier-wave-to-device (CW2D) provides a device with a carrier wave (CW) that can carry information.

[0145] The reader / writer can be a base station or a relay UE.

[0148] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0149] In some implementations, digital mobile communications such as 2G, 3G, 4G, and now 5G have effectively met people's needs in voice communication, digital mobile communication, and mobile broadband internet communication. However, with social and economic development, the demand for Internet of Things (IoT) communication has gradually emerged. The 3rd Generation Partnership Project (3GPP) has standardized a series of IoT technologies and devices, including MTC, NB-IoT, and RedCap. Among them, MTC and NB-IoT significantly reduce the cost of IoT terminals by employing technologies such as small bandwidth, single antenna, reduced peak data rate, half-duplex, and reduced transmit power. Furthermore, the introduction of enhanced discontinuous reception (eDRX) and power saving mode (PSM) greatly reduces the power consumption of IoT terminals. At the same time, MTC and NB-IoT can support a large number of IoT terminals accessing the network, thereby meeting the demand for massive connectivity. In recent years, the Internet of Things (IoT) based on NB-IoT and eMTC technologies has been widely tested and commercialized, such as in smart grids, smart parking, smart transportation / logistics, and smart energy management systems. It covers many vertical fields such as smart cities, smart homes, and smart factories, and has rapidly promoted the upgrading and transformation of traditional industries.

[0150] In some implementations, within A-IoT technology, one scenario involves the inventory process between terminal 101 (e.g., an A-IoT device) and network device 102 (e.g., a gNB). Figure 1D As shown, the inventory process for A-IoT may be completed through a 3-step random access process or a 2-step random access process.

[0151] in:

[0152] The inventory process can be triggered by an inventory trigger message (R2D#1) sent by network device 102. R2D#1 can be a paging message used to trigger inventory and time slot allocation.

[0153] After receiving the inventory trigger message, the A-IoT device will generate and send a random number message (D2R#1). D2R#1 can refer to the 16-bit random number (RN16) in the Radio Frequency Identification (RFID) system for random number generation.

[0154] After receiving the random number message, network device 102 sends a random number response message (R2D#2) to the A-IoT device. R2D#2 can refer to the ACK response in RFID and is used to respond to the random number. In addition, network device 102 allocates time domain and / or frequency domain resources for the identification reporting message (D2R#2) in the random number response message. D2R#2 can refer to the Electronic Product Code (EPC) in RFID.

[0155] Finally, the A-IoT device sends an identifier reporting message (D2R#2) based on the time domain and / or frequency domain resources allocated by the random number response message to report the identifier.

[0156] For example, the signaling name of R2D#1 can be Paging, the signaling name of D2R#1 can be Msg1, the signaling name of R2D#2 can be Msg2, and the signaling name of D2R#2 can be Msg3.

[0157] After inventory is completed, A-IoT devices with command services will continue to receive command messages from network devices and send response messages to network devices at specific time and / or frequency domain resource locations based on the indication information contained in the command messages.

[0158] In the above embodiments, Msg1, Msg3, or response messages in response to command messages all belong to D2R messages. For example, the frequency domain resources for transmitting D2R messages can be determined by relevant parameters, such as at least two of the following: time domain length Tb based on bit occupancy, minimum time domain unit Tchip, and number of line code repetitions R. However, the related art only illustrates all possible values ​​of the relevant parameters; how to indicate and determine the frequency domain resources for A-IoT devices to transmit messages such as D2R messages based on parameter values ​​is a problem that needs to be solved.

[0159] Figure 2A This is an interactive schematic diagram illustrating an indication method according to an embodiment of the present disclosure. For example... Figure 2A As shown, the embodiments of this disclosure relate to an instruction method, which includes:

[0160] In step S2101, network device 102 sends first information to terminal 101.

[0161] In some embodiments, network device 102 and terminal 101 may refer to Figures 1A to 1C For example, in the description of the embodiments, terminal 101 is an A-IoT device.

[0162] In some embodiments, network device 102 receives first information.

[0163] In some embodiments, the first information may be an R2D message.

[0164] In some embodiments, the first information is used to determine the frequency domain resources for the terminal to transmit the second information.

[0165] For example, the second information is a unicast message. For instance, a network device schedules the transmission of a second information via a signaling (such as a scheduling signaling or scheduling message).

[0166] For example, the second information is a D2R transmission or a D2R message. For instance, the second information is a unicast D2R message.

[0167] For example, terms such as second information and second message can be used interchangeably.

[0168] For example, the first information is used to determine the frequency domain resources for the terminal to transmit the second message; for example, the first information is used to determine the frequency domain resources for the terminal to transmit D2R messages; for example, the first information is used to determine the frequency domain resources for the terminal to perform D2R transmission.

[0169] In some embodiments, the first information includes at least one of the following parameters for determining frequency domain resources:

[0170] The time domain length Tb occupied by a bit;

[0171] Small frequency shift coefficient R;

[0172] Tb and R are used to determine frequency domain resources.

[0173] For example, the time domain length occupied by a bit can refer to the bit duration, which can be the time domain length occupied by an encoded bit or the time domain length occupied by a repeated bit.

[0174] For example, the small frequency shift coefficient R can also be referred to as the number of encoding repetitions.

[0175] For example, R can be the number of repetitions of the line code. The line code is used to implement signal frequency shifting and can include Manchester encoding, pulse width encoding (PIE), and biphase spacing code encoding (FM0). This disclosure uses Manchester encoding as an example for illustration.

[0176] For example, combined Figure 2C As shown, the smallest time-domain unit Tchip in Tb can be the time-domain length occupied by a D2R unit (chip). Tchip can be determined based on Tb and R, or the first information can indicate Tchip independently.

[0177] For example, D2R transmission can achieve spectrum shifting through Manchester coding. Wherein, such as Figure 2B As shown, the Manchester encoding rule is that two levels, one high and one low (10), represent bit 0, and two levels, one low and one high (01), represent bit 1. Frequency shifting can be achieved by repeating the Manchester encoding.

[0178] For example, such as Figure 2C The time-domain signal waveform diagram shown, and as follows Figure 2D The signal spectrum diagrams shown are as follows: When the time domain length Tb representing a single coded (FEC) bit or a repeated (block repeat) bit is fixed, and the Manchester code repetition count R is 1, the corresponding signal spectrum is the frequency domain resource range represented by the dashed line centered at Fc (label ①), where Fc is the frequency position of the carrier signal and the carrier signal is a single-carrier signal (occupying only one frequency point). When the time domain length Tb representing a single coded (FEC) bit or a repeated (block repeat) bit is fixed, and the Manchester code repetition count R is 2, the corresponding signal spectrum is the frequency domain resource range represented by the solid line centered at Fc (label ②), where Fc is the frequency position of the carrier signal and the carrier signal is a single-carrier signal (occupying only one frequency point). Here, FEC refers to Forward Error Correction (FEC) code, such as a convolutional code.

[0179] Where Tb determines the frequency domain width occupied by the frequency-division signal, and R determines the frequency shift position. For example... Figure 2D The signals with different R values ​​shown have the same frequency bandwidth. The center frequency of the spectrum represented by the solid line in region ② is twice that of the center frequency of the spectrum represented by the dashed line in region ①, which is exactly the same as the number of repetitions of the Manchester encoding in the time domain.

[0180] For example, terminal 101 is based on backscatter communication, such as D2R messages which are transmitted based on backscatter. That is, terminal 101 does not generate its own carrier signal, but transmits its own information by reflecting an external carrier signal and loading it with the signal. The center frequency position of the reflected signal is the frequency position Fc of the carrier signal.

[0181] For example, Tb, R and Tchip can have a mapping relationship as shown in Table 2-1. Based on Table 2-1, all possible values ​​of Tb, R and Tchip can be determined.

[0182] Table 2-1

[0183]

[0184] In some embodiments, the first information includes at least one of the following:

[0185] The first instruction information is used to indicate Tb;

[0186] The second instruction information is used to instruct R.

[0187] For example, any indication information may occupy one or more bits.

[0188] For example, the first indication information and the second indication information are carried in the R2D message. For instance, the first indication information and the second indication information are carried in the higher-level signaling (such as MAC signaling) of the R2D message.

[0189] In the first embodiment, the first indication information includes N bits for indicating Tb, and the value of Tb is indicated by the value of the N bits; wherein, there is a mapping relationship between different values ​​of the N bits and different values ​​of Tb, and N is an integer determined according to the number of values ​​of Tb.

[0190] In this embodiment, as shown in Table 2-1, there are a total of 8 possible values ​​for Tb, which can belong to the value set {266.67, 133.33, 66.67, 33.33, 16.67, 8.33, 4.17, 1.39}.

[0191] In this embodiment, the first indication information can indicate the available Tb value in a second information transmission using a fixed N bits, such as indicating the available Tb value in the above set.

[0192] In this embodiment, N can be equal to 3 or an integer greater than 3, depending on the number of possible Tb values. For example, if N = 3, the first indication information uses 3 bits to indicate the Tb value. Different 3-bit values ​​correspond to different Tb values.

[0193] In one example, as shown in Table 2-2, the value of Tb can be indicated based on the mapping relationship between the 3-bit value (code point) of the first indication information and Tb. For example, when the 3-bit value is 000, the value of Tb is indicated as 266.67. It is understood that this example is for illustrative purposes only. Following the order in Table 2-2, Tb values ​​can correspond one-to-one with the code point values ​​on the left side of the table from largest to smallest. Alternatively, Tb values ​​can correspond one-to-one with the code point values ​​on the left side of the table from smallest to largest, or the code points and Tb values ​​can correspond in any other order.

[0194] Table 2-2

[0195] Codepoint The value of Tb 000 266.67 001 133.33 010 66.67 011 33.33 100 16.67 101 8.33 110 4.17 111 1.39

[0196] In the second embodiment, the second indication information includes M bits for indicating R, and the value of R is indicated by the value of the M bits; wherein, there is a mapping relationship between different values ​​of the M bits and different values ​​of R.

[0197] In this embodiment, as shown in Table 2-1, there are a total of 8 possible values ​​for R, which can belong to the value set {1, 2, 4, 8, 16, 32, 64, 128}.

[0198] In this embodiment, the second indication information can further indicate the R value available during a second information transmission process within the aforementioned set.

[0199] In this embodiment, M is determined based on the number of possible values ​​for R. Depending on the number of possible values ​​for R, M can be a fixed value or a variable value.

[0200] In the first example of this embodiment, M can be a fixed value, such as 3, and the second indication information indicates eight possible values ​​of R using 3 bits. Different values ​​of the 3 bits correspond to different values ​​of R.

[0201] As shown in Table 2-3, based on the mapping relationship between the 3-bit value (code point) of the second indication information and R, the value of R can be indicated based on the 3-bit value. For example, when the 3-bit value is 010, the value of R is indicated as 4. It is understood that this example is for illustration only. Following the order in Table 2-2, the values ​​of R from smallest to largest correspond one-to-one with the code point values ​​on the left side of the table. Alternatively, the values ​​of R can correspond one-to-one with the code point values ​​on the left side of the table from largest to smallest, or the code points and R values ​​can correspond one-to-one in other orders.

[0204] In the second example of this embodiment, M is a variable value that can dynamically indicate the value of R. M is associated with the value of Tb, as shown in Table 2-1, where there is a mapping relationship between the values ​​of Tb and R.

[0205] In this example, the maximum value of M is 3.

[0206] In one approach to this example, M can be 1, 2, or 3 based on the value of Tb. For instance, referring to Table 2-1, M equals 3 when Tb is greater than or equal to the first value. M equals 2 when Tb is greater than the second value and less than the first value. M equals 1 when Tb is less than or equal to the second value.

[0207] As shown in Table 2-1, the first value can be 33.33 and the second value can be 4.17.

[0208] In the corresponding rows 4 to 7 of the table, when the value of Tb is greater than or equal to 33.33, such as when the value of Tb is 266.67, 133.33, 66.67 or 33.33, M=3, that is, the number of indicator bits used for R is 3. A maximum of 8 R values ​​can be indicated through 3 bits, as shown in Table 2-3.

[0209] In the corresponding eighth and ninth rows of the table, when Tb is greater than 4.17 and less than 33.33, such as when Tb is 16.67 or 8.33, M=2, that is, the number of bits used for R is 2. A maximum of 4 R values ​​can be indicated by 2 bits, as shown in Table 2-4.

[0210] In the corresponding tenth and eleventh rows (last row) of the table, when the value of Tb is less than or equal to 4.17, such as when the value of Tb is 4.17 or 1.39, M=1, that is, the number of bits used for R is 1. A maximum of 2 R values ​​can be indicated by 1 bit, as shown in Table 2-5.

[0214] Code Point The value of R 0 1 1 2

[0215] In another way of this example, based on the value of Tb, M can be 0, 1, 2, or 3.

[0216] For example, referring to Table 2-1, when Tb is greater than or equal to the first value, M equals 3. When Tb is greater than the second value but less than the first value, M equals 2. When Tb is less than or equal to the second value, M equals 1.

[0217] As shown in Table 2-1, the first value can be 33.33 and the second value can be 4.17.

[0218] In the corresponding rows 4 to 7 of the table, when the value of Tb is greater than or equal to 33.33, such as when the value of Tb is 266.67, 133.33, 66.67 or 33.33, M=3, that is, the number of indicator bits used for R is 3. A maximum of 8 R values ​​can be indicated through 3 bits, as shown in Table 2-3.

[0219] In the corresponding eighth and ninth rows of the table, when Tb is greater than 4.17 and less than 33.33, such as when Tb is 16.67 or 8.33, M=2, that is, the number of bits used for R is 2. A maximum of 4 R values ​​can be indicated by 2 bits, as shown in Table 2-4.

[0220] In the tenth row of the table, when the value of Tb is less than or equal to 4.17, such as when the value of Tb is 4.17, M=1, that is, the number of bits used for R is 1. A maximum of 2 R values ​​can be indicated by 1 bit, as shown in Table 2-4.

[0221] For example, M can be equal to 0 if R is a default value that satisfies the condition; wherein the condition includes at least one of the following:

[0222] R takes the minimum value within the range of R values, such as 1 in {1, 2, 4, 8, 16, 32, 64, 128}.

[0223] R takes the maximum value within the range of R values, such as 128 in {1, 2, 4, 8, 16, 32, 64, 128}.

[0224] R takes the minimum value within the range of R values ​​associated with any Tb value, such as the minimum value of R associated with each Tb value being 1;

[0225] R is the maximum value within the range of values ​​associated with any value of Tb; the maximum value varies depending on the value of Tb, for example, when Tb = 8.33, the maximum value of R is 4; when Tb = 266.67, the maximum value of R is 128; when Tb = 33.33, the maximum value of R is 16.

[0226] For example, corresponding to the eleventh row (last row) of Table 2-1, assuming that the R value is the default value when Tb is 1.39, then when Tb is 1.39, M = 0, meaning that the number of indicator bits for R corresponding to Tb being 1.39 is 0. Terminal 101 can determine that R is the default value 1 and Tb is 1.39 when M = 0.

[0227] In another way of this example, based on the value of Tb, M can be 0, 1, 2 or 3.

[0228] For example, referring to Table 2-1, when Tb is greater than or equal to the first value, M equals 3. When Tb is greater than the second value but less than the first value, M equals 2. When Tb is less than or equal to the second value, M equals 1.

[0229] As shown in Table 2-1, the first value can be 66.67 and the second value can be 8.33.

[0230] In the corresponding rows 4 to 6 of the table, when the value of Tb is greater than or equal to 66.67, such as when the value of Tb is 266.67, 133.33 or 66.67, M=3, that is, the number of bits used for R is 3. A maximum of 8 R values ​​can be indicated through 3 bits, as shown in Table 2-6, indicating other R values ​​except R=1;

[0231] In the corresponding seventh and eighth rows of the table, when Tb is greater than 8.33 and less than 66.67, such as when Tb is 33.33 or 16.67, M=2, that is, the number of bits used for R is 2. A maximum of 4 R values ​​can be indicated by 2 bits. Please refer to Table 2-7 to indicate other R values ​​except R=1.

[0232] In the corresponding ninth and tenth rows of the table, when the value of Tb is less than or equal to 8.33, such as when the value of Tb is 8.33 or 4.17, M=1, that is, the number of bits used for R is 1. A maximum of 2 R values ​​can be indicated by 1 bit. Please refer to Table 2-8 for indicating other R values ​​besides R=1.

[0233] For example, M can be equal to 0 if R is a default value that satisfies the condition; wherein the condition includes at least one of the following:

[0234] R takes the minimum value within the range of R values, such as 1 in {1, 2, 4, 8, 16, 32, 64, 128}.

[0235] R takes the maximum value within the range of R values, such as 128 in {1, 2, 4, 8, 16, 32, 64, 128}.

[0236] R takes the minimum value within the range of R values ​​associated with any Tb value, such as the minimum value of R associated with each Tb value being 1;

[0237] R is the maximum value within the range of values ​​associated with any value of Tb; the maximum value varies depending on the value of Tb, for example, when Tb = 8.33, the maximum value of R is 4; when Tb = 266.67, the maximum value of R is 128; when Tb = 33.33, the maximum value of R is 16.

[0238] For example, in the eleventh row (last row) of Table 2-1, and in other rows where R=1, the value of R is 1, which can be considered the default value and does not require bit indication.

[0239] Assuming that the value of R is the default value when Tb is 1.39, then when Tb is 1.39, M = 0, meaning that the number of indicator bits for R corresponding to Tb being 1.39 is 0. Terminal 101 can determine that R is the default value of 1 when Tb is 1.39 and M = 0.

[0240] Assuming Tb takes the values ​​266.67, 133.33, or 66.67, R = 1 is the default value, and M can be 0 for this default value. Therefore, when Tb takes the values ​​266.67, 133.33, or 66.67, M = 0 indicates that R takes the default value of 1.

[0241] Assuming Tb takes the value of 33.33 or 16.67, R = 1 is the default value, and M can be 0 for this default value. Therefore, when Tb takes the value of 33.33 or 16.67, M = 0 means that R takes the default value of 1.

[0242] Assuming Tb takes the value of 8.33 or 4.17, R = 1 is the default value, and M can be 0 for this default value. Therefore, when Tb takes the value of 8.33 or 4.17, M = 0 means that R takes the default value of 1.

[0243] For example, the default value can also be the maximum value corresponding to each possible value of Tb. Suppose that when Tb is 266.67, R = 128 is the default value; then when Tb is 266.67, M = 0 indicates that R takes the default value of 128. Suppose that when Tb is 133.33, R = 64 is the default value; then when Tb is 133.33, M = 0 indicates that R takes the default value of 64. Suppose that when Tb is 66.67, R = 32 is the default value; then when Tb is 66.67, M = 0 indicates that R takes the default value of 32. Suppose that when Tb is 33.33, R = 16 is the default value; then when Tb is 33.33, M = 0 indicates that R takes the default value of 16. Suppose that when Tb is 16.67, R = 8 is the default value; then when Tb is 16.67, M = 0 indicates that R takes the default value of 8. If Tb is 8.33 and R = 4 is the default value, then M = 0 when Tb is 8.33 indicates that R takes the default value of 4. If Tb is 4.17 and R = 2 is the default value, then M = 0 when Tb is 4.17 indicates that R takes the default value of 2.

[0250] In this example, combining the different methods described above, the number of R values ​​associated with the Tb value is less than or equal to the number of values ​​that M bits can indicate; or, the number of non-default R values ​​associated with the Tb value is less than or equal to the number of values ​​that M bits can indicate.

[0251] Optionally, the number of values ​​that M bits can indicate can refer to the maximum number of R values ​​that M bits can indicate, or the maximum number of R values ​​that can be indicated. For example, when M=1, the number of values ​​that can be indicated is 2; when M=2, the number of values ​​that can be indicated is 4; and when M=3, the number of values ​​that can be indicated is 8.

[0252] Optionally, the number of values ​​that M bits can indicate can be preconfigured or predefined by the protocol.

[0253] In the different examples of this embodiment, the R value indicated by the second indication information needs to meet the restrictions in Table 2-1. For example, for different Tb values, the R value indicated by the second indication information should be within the range of R values ​​associated with that Tb value.

[0254] For example, if Tb is 16.67, the R value indicated by the second indication information needs to be included in the set {1, 2, 4, 8}; or, if Tb is 33.33, the R value indicated by the second indication information needs to be included in the set {1, 2, 4, 8, 16}; or, if Tb is 66.67, the R value indicated by the bitmap needs to be included in the set {1, 2, 4, 8, 16, 32}.

[0255] In some embodiments, in step S2101, network device 102 may schedule only one terminal 101. For example, in a scenario where a user is scheduled in a non-contention-free random access procedure (CFRA), network device 102 may use the above first indication information and second indication information to indicate the parameters for determining the frequency domain resources of the terminal 101.

[0256] In some embodiments, if network device 102 schedules multiple terminals 101, such as scheduling multiple users in CFRA, network device 102 may use the above first indication information and second indication information to indicate and determine the parameters of frequency domain resources of different terminals 101.

[0257] For example, when there are multiple terminals, the number of first indication information can remain unchanged. For instance, if the number of bits in the first indication information remains unchanged, N bits can still be used to indicate the common Tb value of multiple terminals. Alternatively, the number of first indication information corresponds to the number of terminals. For example, if the number of terminals is K, the number of bits occupied by K first indication information is N*K.

[0258] For example, such as Figure 2EAs shown, when there are multiple terminals, the number of second indication messages is also multiple. For example, the first information includes multiple second indication messages, where each second indication message corresponds to one terminal. Referring to the different embodiments of the above-described second indication messages, if the number of bits for each second indication message is M and the number of terminals is K, then the number of bits occupied by the K second indication messages is M*K.

[0289] This disclosure provides a method for indicating the frequency domain resources of a unicast D2R message using a bit duration Tb and a Manchester-coded repetition count R. This method addresses the issues of how to indicate the value of Tb and how to indicate the value of R. For example, the method in this disclosure also proposes the number of bits required to indicate Tb, the number of bits required to indicate R, whether the number of bits is fixed, and whether it is related to the value of Tb. Here, unicast refers to a scheduling message scheduling one D2R transmission.

[0290] For example, the unicast D2R message corresponds to the second information in the above embodiments.

[0291] To facilitate understanding of the methods in the embodiments of this disclosure, the following description is provided through examples:

[0292] Example 1:

[0293] The AIoT device determines the frequency domain resources based on the first indication information and the second indication information, and transmits D2R on the frequency domain resources. The first indication information is used to indicate the bit duration Tb, and the second indication information is used to indicate the number of Manchester code repetitions.

[0294] The first and second instruction information are carried in the R2D message. Specifically, the first and second instruction information are carried in the higher-level signaling of the R2D message.

[0295] For example, the AIoT device corresponds to the terminal in the foregoing embodiments.

[0296] The specific instructions may include the following examples.

[0297] Example 1-1:

[0298] Tb is a fixed 3-bit indicator, and R is a fixed M-bit indicator.

[0299] Tb belongs to the set {266.67, 133.33, 66.67, 33.33, 16.67, 8.33, 4.17, 1.39}, with a total of 8 possible values. In a single transmission, a fixed 3 bits are used to indicate one of these values. Taking Table 2-2 as an example, when the 3 bits are 000, the value indicating Tb is 266.67.

[0300] R belongs to the set {1, 2, 4, 8, 16, 32, 64, 128}, with a total of 8 possible values. M has a value of 3, meaning that 3 bits are used to indicate the value of R. Taking Table 2-3 as an example, when the 3-bit bitmap is 010, the value of R is 4.

[0301] Examples 1-2:

[0302] Tb is a fixed 3-bit indicator, while R is a variable maximum M-bit indicator.

[0303] Tb belongs to the set {266.67, 133.33, 66.67, 33.33, 16.67, 8.33, 4.17, 1.39}, with a total of 8 possible values. In a single transmission, a fixed 3 bits are used to indicate one of these values. For example, when the 3 bits are 000, the value of Tb is 266.67.

[0304] R belongs to the set {1, 2, 4, 8, 16, 32, 64, 128}, with a total of 8 possible values. Correspondingly, M can be 3. The main difference between Examples 1-2 and 1-1 is that in Example 1-1, the indicator for the value of R uses a fixed number of bits, independent of the value of Tb; in Example 1-2, the indicator for the value of R uses a dynamic indicator, with the specific number of bits related to the value of Tb. The specific association method is as follows:

[0305] The first association method: the bits indicating the value of R can be 1, 2, or 3. As shown in Table 2-1, when the value of Tb is greater than or equal to 33.33, that is, when the value of Tb is 266.67, 133.33, 66.67, or 33.33, the corresponding number of bits indicating R is 3; when the value of Tb is 16.67 or 8.33, the corresponding number of bits indicating R is 2; when the value of Tb is 4.17 or 1.39, the corresponding number of bits indicating R is 1.

[0306] The second association method: the bits indicating the value of R can be 0, 1, 2, or 3. As shown in Table 2-1, when the value of Tb is greater than or equal to 33.33, that is, when the value of Tb is 266.67, 133.33, 66.67, or 33.33, the corresponding number of bits indicating R is 3; when the value of Tb is 16.67 or 8.33, the corresponding number of bits indicating R is 2; when the value of Tb is 4.17, the corresponding number of bits indicating R is 1; when the value of Tb is 1.39, the corresponding number of bits indicating R is 0, that is, R takes the default value of 1.

[0307] The third association method: The bits indicating the value of R can be 0, 1, 2, or 3. As shown in Table 2-1, the gray area represents the case where the number of bits indicating the value of R is 0. In this case, the value of R can be the default value of 1. Furthermore, the value of R can also be the maximum value corresponding to each Tb.

[0308] When the number of bits for the value of R is not 0, such as when the value of Tb is greater than or equal to 66.67, that is, when the value of Tb is 266.67, 133.33 or 66.67, the corresponding number of indicator bits for R is 3; when the value of Tb is 33.33 or 16.67, the corresponding number of indicator bits for R is 2; when the value of Tb is 8.33 or 4.17, the corresponding number of indicator bits for R is 1.

[0309] Examples 1-3:

[0310] Furthermore, the above method can be applied to non-contention-based random access procedure (CFRA), where CFRA schedules only one user.

[0311] Extending this method, it can also be applied to the non-contention-based random access procedure (CFRA), corresponding to the case where CFRA schedules KM users. In this case, the indicator bits of Tb remain unchanged, i.e., they are common to all K users, while the number of indicator bits of R is the number of indicator bits determined in the three association methods × K. Alternatively, the number of indicator bits of Tb can also be increased to K times, and the number of indicator bits of R is the number of indicator bits determined in the three association methods × K.

[0312] Extending this approach, the above method can also be applied to multicast scheduling scenarios. When scheduling K users simultaneously, the indicator bits of Tb remain unchanged, meaning they are a common indicator for all K users, and the number of indicator bits for R is the number of indicator bits determined among the three association methods × K. Alternatively, the number of indicator bits for Tb can also be increased to K times, while the number of indicator bits for R is the number of indicator bits determined among the three association methods × K.

[0313] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
