Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a transmission control method, apparatus, reader, A-IoT device, and network device. Background Technology

[0003] A new type of Internet of Things (IoT) device is Ambient IoT (A-IoT), designed for low-complexity, low-cost, and low-power low-end IoT devices. A-IoT devices have only a limited power supply, characterized by low energy consumption and low cost. Currently, A-IoT includes three device types: Device 1, Device 2a, and Device 2b. Device 1 and Device 2a have no or limited power supply and cannot actively communicate; they can only backscatter received signals, carrying information in the backscattered signal. Device 2b can actively transmit signals. Due to the low power consumption, low complexity, and limited or no power supply of A-IoT devices, their communication distance may be limited in certain scenarios. Therefore, using intermediate nodes for communication can be considered for A-IoT data transmission.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0098] The following is a brief explanation of the relevant concepts mentioned in this disclosure.

[0099] I. Types and Characteristics of A-IoT Devices

[0100] Based on whether A-IoT devices have energy storage capabilities and the ability to independently generate signals, they are divided into the following three categories:

[0101] A. Device 1: It has energy storage capacity but no independent signal generation capability; it transmits signals through backscattering.

[0102] B. Device 2a: It has energy storage capacity but no independent signal generation capability. It transmits signals through backscattering. The stored energy can be used to amplify the power of the backscattered signal.

[0103] C. Device 2b: It has energy storage capacity, independent signal generation capability, and uses radio frequency devices for signal transmission.

[0104] For A-IoT devices, due to their extremely simple receiver structure, they are unable to process New Radio (NR) signals.

[0105] II. Backscatter Communication 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 or external node transmitter (emitter) generates the radio frequency (RF) excitation signal, while the reflective tag is a device capable of reflecting the RF signal. The reader or external node transmitter sends an RF signal to the reflective tag, which receives the signal from the excitation signal source and reflects the RF signal. By changing the load impedance of the reflective tag's antenna, information is modulated into the backscattered signal, which is the device-to-reader (D2R) signal. For example, 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.

[0106] Currently, the aforementioned radio frequency excitation signal is also known as a carrier wave. The generation of the carrier wave currently includes two topologies: inside and outside. When configured as an outside topology, the carrier wave can be provided by an external node, the emitter, which is different from the reader node. If configured as an inside topology, the carrier wave is provided by the reader node.

[0107] III. Network Topology of A-IoT

[0108] A-IoT supports two network Topo structures: one is a Topo structure where gNB and A-IoT are directly connected; the other is a Topo structure where intermediate nodes transmit data to A-IoT. Furthermore, the link from the base station or intermediate node to A-IoT is a Physical Reader to Device Channel (PRDCH), or simply an R2D channel. Signals transmitted via the PRDCH channel are simply referred to as R2D signals. The channel from A-IoT to the base station or intermediate node is a Physical Device to Reader Channel (PDRCH), or simply a D2R channel. Signals transmitted via the PDRCH channel, or signals reflected from the PDRCH channel, are simply referred to as D2R signals.

[0109] In the first topology, A-IoT communicates directly and bidirectionally with the base station. Communication between the base station and A-IoT includes data and / or signaling. This topology includes a base station (BS) that sends signals to A-IoT and a base station (BS) that receives signals from A-IoT; these can be different base station nodes.

[0110] In the second topology, intermediate nodes communicate bidirectionally between A-IoT and the base station. In this topology, intermediate nodes can be relays, IAB nodes, user equipment (UE, also known as terminals), repeaters, etc., all with A-IoT communication capabilities. These intermediate nodes transmit environmental IoT data and / or signaling between the BS and A-IoT.

[0111] This patent focuses on resource scheduling and transmission methods under Topo2.

[0112] IV. Random Access

[0113] The NR system uses random access, where the base station assigns a unique identifier to each terminal device and also identifies which terminal devices have accessed the system. The random access process includes:

[0114] A. The UE sends a sequence of random access preambles (i.e., message 1, Msg1) on the Physical Random Access Channel (PRACH).

[0115] B. The UE receives a Random Access Response (RAR) message (i.e., message 2, Msg2) on the Physical downlink control channel (PDCCH) / Physical downlink shared channel (PDSCH).

[0116] C. The UE sends message 3 (Msg3) on the Physical Uplink Shared Channel (PUSCH);

[0117] D. The UE receives the contention resolution message (i.e., message 4, Msg4) on the PDSCH channel.

[0118] Before the random access procedure, the terminal obtains the set of SS / PBCH (Synchronization Signal / PBCH block, SSB) indexes, physical layer time and frequency resources, random access preamble sequence format, and random access preamble sequence set parameters through system broadcast messages. Then, the UE generates a random access preamble sequence based on the obtained information and initiates random access on the corresponding physical layer random access time and frequency resources.

[0119] The base station performs PRACH detection. If the base station detects a Preamble sequence, it feeds back the corresponding RAR information on the PDCCH / PDSCH. After sending the random access preamble sequence, the terminal checks the RAR information fed back on the downlink PDCCH / PDSCH within a RAR time window. If the corresponding RAR information is detected, it means that the random access preamble sequence sent by the UE has been detected by the base station. This RAR information also includes the UE's uplink timing advance adjustment amount. Based on this adjustment amount, the terminal can obtain uplink synchronization and then send an uplink resource scheduling request message for subsequent data transmission.

[0120] Furthermore, the random access process also includes:

[0121] A. The terminal sends message 1, which contains not only the random access Preamble sequence but also uplink data.

[0122] B. The base station sends message 2. In addition to the random access preamble identifier and timing advance command word (TAC), message 2 also contains the UE ID or cell radio network temporary identifier (C-RNTI) for contention resolution.

[0123] The current random access procedure for base stations and A-IoT transmission under topo1 includes 3 steps of RACH:

[0124] Step A: The base station sends a Paging message;

[0125] Step B: A-IoT sends Msg1;

[0126] Step C: The base station sends a Msg2 message in response to A-IoT's Msg1 message;

[0127] Step D: A-IoT sends a Msg3 message, carrying A-IoT unique identification information or data information.

[0128] In related technologies, the scheduling of random access information includes methods for scheduling random access of the UE during NR and UE communication, and methods for scheduling random access of the base station for configuring A-IoT.

[0129] Currently, for the random access scheduling and transmission methods of A-IoT devices in Topo1, the base station uses either higher-layer signaling or L1 control signaling for indication. Higher-layer signaling refers to physical layer-invisible data information carried in the PRDCH channel, while L1 control signaling refers to control information carried in the PRDCH channel. The specific scheduling methods and parameters for Msg0, Msg1, Msg2, and Msg3 remain unresolved.

[0130] There is currently no solution for scheduling and transmission methods for random access of A-IoT devices in Topo2. The technical differences between Topo2's scheduling and transmission methods for random access of A-IoT devices and Topo1 are as follows:

[0131] 1) Under Topo1, the transmission of random access information between the base station and A-IoT devices, and the scheduling of each signaling transmitted between the base station and A-IoT devices are completed by the base station.

[0132] Topo2 adopts a similar approach to Topo1, where each signaling message is scheduled by the base station. Therefore, for each message, the base station first schedules the Reader UE to send the A-IoT transmission information to the Reader UE, and then the base station schedules the Reader UE to send the A-IoT information to the A-IoT device. As a result, for a single message, at least two base station scheduling operations are required to complete the transmission of the message, which greatly reduces the A-IoT transmission efficiency and increases the latency of random access in A-IoT.

[0133] 2) For Topo2, if the scheduling method of Topo1 is followed, in addition to the fact that a message in 1) above needs to be scheduled twice, there will also be that the transmission of Reader UE and A-IoT is transmitted on the uplink (UL) spectrum resources of the base station. Therefore, after the base station schedules Reader UE, it will also introduce downlink (DL), UL and time slot configuration delays, which will further increase the delay of A-IoT random access.

[0134] Currently, the scheduling of random access information in NR, Msg1, is done through predefined resource configuration, while Msg2, Msg3, and Msg4 are scheduled through PDCCH scheduling signaling. If applied to intermediate nodes / UEreaders and A-IoT, the following problems will exist:

[0135] 1) Intermediate nodes do not have the ability to send NR DL PDCCH.

[0136] When the intermediate node is a UE, the UE cannot send DL PDCCH, thus failing to complete the scheduling of A-IoT transmission.

[0137] 2) When random access transmission occurs between intermediate nodes and A-IoT devices, the resources and parameters for random access are determined not only by the intermediate nodes but also by the base station. Therefore, compared to related technologies, the scheduling and transmission of random access in A-IoT require coordination among the base station, intermediate nodes, and A-IoT devices to complete the random access of A-IoT devices.

[0138] Based on the above analysis, this disclosure proposes a method for scheduling and transmission of random access between intermediate nodes / UE readers and A-IoT devices. Furthermore, it is also applicable to data transmission between Reader UEs and A-IoT devices after random access.

[0139] The embodiments of this disclosure are described below with reference to the accompanying drawings. The transmission control method, apparatus, reader, A-IoT device, and network device provided in the embodiments of this disclosure can be applied to wireless communication systems. This wireless communication system can be a system employing fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will understand that the 5G NR system is merely an example and not a limitation.

[0140] In some embodiments, the structure of a network system to which this disclosure applies includes a user terminal and a base station. The user terminal can be user equipment (UE), such as a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), or wearable device. It should be noted that this disclosure does not limit the specific type of user terminal. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB), or a base station in other communication systems, also referred to as a node B. It should be noted that this disclosure uses a 5G base station as an example only, but does not limit the specific type of base station.

[0149] It should be noted that in this case, the first set of scheduling information can be understood as either predefined for the reader and / or A-IoT device, or it can be semi-statically indicated to the reader and / or A-IoT device by the network device.

[0150] In some embodiments, this situation includes the following two options:

[0151] Option 1: The A-IoT device obtains a first set of scheduling information through predefined and / or semi-static means by the network device; the network device provides the reader and / or A-IoT device with a first set of scheduling information through predefined and / or semi-static means.

[0152] In some embodiments, the first scheduling information set includes all scheduling information for random access and / or data transmission between the reader and the A-IoT device.

[0153] In some embodiments, the total scheduling information includes: total scheduling information for the reader to receive random access and / or data transmission from A-IoT devices, and total scheduling information for the reader to send random access and / or data transmission to A-IoT devices.

[0154] Option 2: The A-IoT device obtains at least two sets of first scheduling information through predefined and / or semi-static network devices; the network device provides at least two sets of first scheduling information to the reader and / or A-IoT device through predefined and / or semi-static instructions.

[0155] In some embodiments, each of the first scheduling information sets includes partial information on random access and / or data transmission between the reader and the A-IoT device, and the at least two first scheduling information sets jointly complete the random access and / or data transmission between the reader and the A-IoT device.

[0156] In some embodiments, in a case where two first scheduling information sets are included, the two first scheduling information sets satisfy at least one of A21-A23:

[0157] A21. A first scheduling information set is used to instruct the reader to send Reader To Device (R2D) information, and another first scheduling information set is used to instruct the A-IoT device to send Device To Reader (D2R) information.

[0158] Another way to express this is as follows: a first set of scheduling information is used to instruct the reader to receive D2R information, and another first set of scheduling information is used to instruct the A-IoT device to receive R2D information.

[0159] A22. A first scheduling information set is used to indicate the scheduling information set of at least one of message 0, paging message and message 2, and another first scheduling information set is used to indicate the scheduling information set of at least one of message 1 and message 3.

[0160] A23. A first scheduling information set is used to indicate the scheduling information set between the reader and the A-IoT device, and another first scheduling information set is used to indicate the scheduling information set between the reader and the network device, and / or the scheduling information set between the A-IoT device and the network device.

[0161] It should be noted that the information transmission indicated by the aforementioned scheduling information set can be time-division multiplexed (TDD) or frequency-division multiplexed (FDD). The time-division multiplexing can be a first scheduling information set indicating a first time point as the start time, a duration of the first time point, and an end time of the second time point; if a period is supported, it is a scheduling information set for the first period. The second first scheduling information set indicates a third time point as the start time, a duration of the second time point, and an end time of the fourth time point; if a period is supported, it is a scheduling information set for the second period. The frequency-division multiplexing can be a first scheduling information set indicating a first frequency point as the start time with a continuous frequency / bandwidth of the first frequency / bandwidth; if frequency hopping is supported, it is a scheduling information set with predefined frequency hopping rules. The second first scheduling information set indicates a second frequency point as the start time with a continuous frequency / bandwidth of the second frequency / bandwidth.

[0162] In some embodiments, in another case, when four first scheduling information sets are included, the four first scheduling information sets satisfy the following:

[0163] The first first scheduling information set is used to indicate the scheduling information set of paging message and / or message 0, the second first scheduling information set is used to indicate the scheduling information set of message 1, the third first scheduling information set is used to indicate the scheduling information set of message 2, and the fourth first scheduling information set is used to indicate the scheduling information set of message 3.

[0164] This situation can be understood as using different sets of scheduling information to indicate the scheduling information for different messages under random access.

[0165] In some embodiments, network devices may provide a semi-static indication of a first set of scheduling information via RRC signaling.

[0166] For example, as shown in Figure 2, the network device is semi-statically configured with at least one first scheduling information. For instance, RRC configuration 1 indicates the first first scheduling information set, RRC configuration 2 indicates the second first scheduling information set, and RRC configuration 3 indicates the third first scheduling information set. Specifically, Scheme 1 corresponds to one first scheduling information set indicated by RRC configuration 1, indicating all scheduling information for random access and / or data transmission between the reader and the A-IoT device. Scheme 2 corresponds to two first scheduling information sets indicated by RRC configuration 2 and RRC configuration 3, which together complete the random access and / or data transmission between the reader and the A-IoT device. Specifically, RRC configuration 2 is used to indicate the transmission of random access information or R2D information for Msg0 and Msg2, and RRC configuration 3 is used to indicate the transmission of random access information or D2R information for Msg1 and Msg3.

[0167] A12. Obtain first information of the first scheduling information set of the semi-static indication of the network device, and obtain first information of at least one first scheduling information set of the dynamic signaling activation or validity time indication of the network device, wherein the first information includes at least one of the following: resource indication information, transmission direction indication information, transmission parameter information, and transmission message indication information.

[0168] It should be noted that, in this case, the first information in the first scheduling information set can be understood as a semi-static indication from the network device to the A-IoT device and / or the reader, and the activation of the first information is indicated by the network device's dynamic signaling or validity period. Furthermore, in this case, the reader also needs to indicate a fourth piece of information to the A-IoT device via dynamic signaling. This fourth piece of information includes information other than the first information from resource indication information, transmission direction indication information, transmission parameter information, and transmission message indication information.

[0169] In some embodiments, this situation includes one of the following:

[0170] Scheme 3: The A-IoT device obtains a first scheduling information set through at least one of predefined methods, semi-static network device indication, dynamic network device indication, and reader indication; specifically, the network device provides the reader and / or A-IoT device with the first information of the first scheduling information set through semi-static indication, and the network device instructs the reader and / or A-IoT device to activate and use the first information through dynamic signaling activation or validity time indication; the reader instructs the A-IoT device to indicate the fourth information through dynamic signaling.

[0171] As shown in Figure 3, the resource indication information of the reader and the A-IoT device is semi-statically indicated by the network device. The reader obtains the resource indication information based on the semi-static indication of the network device or by dynamically activating at least one semi-static indication. On the obtained resource indication information, the reader autonomously indicates at least one of the following: transmission direction indication information, transmission parameter information, and transmission message indication information.

[0173] It should be noted that in this case, the information in the first set of scheduling information obtained by the reader and the A-IoT device is either a semi-static indication or a dynamic indication from the network device.

[0666] The following are examples illustrating specific applications of this disclosure.

[0667] In some embodiments, the length of each field in this disclosure may differ for different scheduling signaling. Field lengths are non-negative integers. In the following application scenarios, the length of each field is illustrative and not intended to be a specific limitation.

[0668] Application Scenario 1: Msg0 schedules an A-IoT device to transmit Msg1 using a non-contention-based random access method.

[0669] In some embodiments, the first field set includes:

[0670] The first indication information, for example, is the transport block size (TBS) of the R2D signal: 8 bits, indicating the total length of the PRDCH carrying Msg0, for example, 40 bits.

[0671] The second field set includes the following information:

[0672] Access type information: 1 bit, indicating that the random access method is based on non-contention-based random access;

[0673] The second indication information, for example, is D2R TBS: 5 bits, for example, indicating that Msg1's TBS is 32 bits;

[0674] Bit transmission rate: 3 bits, for example, indicating that the bit transmission rate of Msg1 is 56 kbps;

[0675] Forward error correction coding enable: 1 bit, for example, indicating that Msg1 uses forward error correction coding;

[0676] Block retransmission count: 2-3 bits, for example, the block retransmission count for Msg1 is 1;

[0677] Time-domain resource start position: 4 bits, for example, indicating that the time-domain resource start time of Msg1 is 5 OFDM symbols after the end time of Msg0;

[0678] The time interval between adjacent D2R time-domain transmission resources, or the time-domain length of a D2R transmission resource: 3 bits, for example, indicating that the time-domain length of Msg1's transmission resource is 1 time slot;

[0679] Number of time-domain transmission resources: Under non-contention-based random access, only one D2R msg1 transmission is scheduled for each msg0, therefore the length of this field is 0 bits;

[0680] Symbol rate: 3 bits, for example, indicating that the symbol rate of Msg1 is 56 kbps;

[0681] Segmented retransmission indication: Since Msg1 is short, it does not need to be segmented for transmission, so this field is 0 bits.

[0682] The fifth indication information, for example, is a device identifier: the length is the length of the device identifier, for example, indicating that the device with the identifier 00011100 can access the network.

[0683] Frequency shift factor: log2Y max bits, where Y max This represents the maximum number of frequency shift factors that an A-IoT device can support. For example, it indicates a frequency shift factor R = 0, meaning no frequency shifting will occur.

[0684] The fourth information, for example, is padding bits: the length of the padding bits is determined according to the indication of the predefined TBS set and / or the first field set, for example, 14 bits.

[0685] Based on this DCI format design, A-IoT devices can determine the total length of the PRDCH carrying msg0 according to the first field set, thereby performing cyclic redundancy check (CRC), and determine the transmission parameters of Msg1 by decoding each field in the second field set.

[0686] Application Scenario 2: Msg0 schedules multiple A-IoT devices to transmit Msg1 using a contention-based random access method.

[0687] Specifically, the first set of fields includes:

[0688] The first indication information, for example, is the TBS of the R2D signal: 8 bits, indicating the total length of the PRDCH carrying Msg0, for example, 96 bits;

[0689] The second set of fields includes:

[0690] Access type information: 1 bit, indicating that the random access method is contention-based random access.

[0691] The second indication information, for example, is D2R TBS: 5 bits, for example, indicating that Msg1's TBS is 16 bits;

[0692] Bit transmission rate: 3 bits, for example, the TBS for Msg1 is 56kbps;

[0693] Forward error correction coding enable: 1 bit, for example, indicating that Msg1 does not use forward error correction coding;

[0694] Block retransmission count: 2-3 bits, for example, the block retransmission count for Msg1 is 1;

[0695] Time-domain resource start position: 4 bits, for example, indicating that the time-domain resource start time of Msg1 is 5 OFDM symbols after the end time of Msg0;

[0696] The time interval between adjacent D2R time-domain transmission resources, or the time-domain length of a D2R transmission resource: 3 bits, for example, indicating that the time-domain length of Msg1's transmission resource is 1 time slot;

[0697] Number of time-domain transmission resources: 1 to 3 bits, for example, indicating that the number of time-domain transmission resources is 2;

[0698] Symbol rate: 3 bits, for example, indicating that the symbol rate of Msg1 is 56 kbps;

[0699] Segmented retransmission indication: Since Msg1 is short, it does not need to be segmented for transmission, so this field is 0 bits;

[0700] The fifth indication information, for example, is the device identifier: In contention-based random access, the reader does not know the device identifier when sending msg0, so this field is 0 bits;

[0701] Frequency shift factor: log2Y max bits, where Ymax This field represents the maximum number of frequency shift factors that an A-IoT device can support. For example, if this field indicates a frequency shift factor R = 14, then the A-IoT device will randomly select one of the available R values ​​less than 14 for frequency shifting of Msg1; or 0 bits, indicating that the A-IoT device will randomly select one of all available R values ​​for frequency shifting of Msg1.

[0702] The fourth piece of information, for example, is padding bits: the length of the padding bits is determined based on the predefined TBS set and / or the indication of the first field, for example, 49 bits.

[0703] Based on this DCI format design, A-IoT devices can determine the total length of the PRDCH carrying msg0 according to the first field set, thereby performing CRC, and determine the transmission parameters of Msg1 by decoding each field in the second field set.

[0704] Application Scenario 3: Msg2 schedules 4 A-IoT devices to transmit Msg3

[0705] Specifically, the first set of fields includes:

[0706] The first indication information, for example, is the TBS of the R2D signal: 8 bits, indicating the total length of the PRDCH carrying Msg2, for example, 208 bits.

[0707] The second set of fields includes:

[0708] Access type information: This field is only required in msg0, therefore it is 0 bits in msg2.

[0709] The second indication information, for example, is D2R TBS: 5 bits, for example, indicating that the TBS of Msg3 is 16 bits;

[0710] Bit transmission rate: 3 bits, for example, the bit transmission rate of Msg3 is 56kbps;

[0711] Forward error correction coding enable: 1 bit, for example, indicating that Msg3 uses forward error correction coding;

[0712] Block retransmission count: 2-3 bits, for example, the block retransmission count for Msg3 is 1;

[0713] Time-domain resource start position: 4 bits, for example, indicating that the time-domain resource start time of Msg3 is 5 OFDM symbols after the end time of Msg0;

[0714] The time interval between adjacent D2R time-domain transmission resources, or the time-domain length of a D2R transmission resource: 3 bits, for example, indicating that the time-domain length of the transmission resource for Msg3 is 2 time slots;

[0715] Number of time-domain transmission resources: 1 to 3 bits, indicating that the number of time-domain transmission resources is 4;

[0716] Symbol rate: 3 bits, for example, indicating that the symbol rate of Msg3 is 56 kbps;

[0717] Segmented retransmission indication: Assuming msg3 is transmitted in segments, this field is 1 bit long and indicates whether the A-IoT device should transmit a new msg3 segment or retransmit the previous msg3 segment.

[0718] The fifth indication information, for example, is the device identifier: device random identifier length * number of devices = 16 * 4 = 64.

[0719] Frequency relocation factor: number of devices * log2Y max bits, where Y max This represents the maximum number of frequency shift factors that an A-IoT device can support. For example, it indicates that the four Msg3s use frequency shift factors of 2, 6, 10, and 14, respectively.

[0720] The fourth piece of information, for example, is padding bits: the length of the padding bits is determined based on the predefined TBS set and / or the indication of the first field, for example, 99 bits.

[0721] Based on this DCI format design, A-IoT devices can determine the total length of the PRDCH carrying msg2 according to the first field set, thereby performing CRC, and determine the transmission parameters of Msg3 by decoding each field in the second field set.

[0722] Application Scenario 4: The "Write" command schedules one A-IoT device to perform a write operation.

[0723] Specifically, the first set of fields includes:

[0724] The first indication information, for example, is the TBS of the R2D signal: 8 bits, indicating the total length of the PRDCH carrying Msg2, for example, 8 bits.

[0725] Based on this DCI format design, the A-IoT device can determine that the total length of the PRDCH carrying the command is 8 bits, which is equal to the length of the first field set, and then determine that the length of the second field set is zero, and know that the command is not used to schedule D2R transmission.

[0726] Application Scenario 5: Method for Determining the Length of Each Field in the Second Field Set

[0727] A-IoT devices can determine the existence of each field in the second field set and / or the length of each field based on the R2D control information carried in the scheduling signaling. The R2D control information can be at least one of the following:

[0728] J51, TBS of the R2D signal in the first field set;

[0729] J52, signaling type or message type, for example, used for indication:

[0730] This signaling indicates whether it is used for commands or for access;

[0731] This signaling indicates that it is used for specific functions such as reading, writing, scheduling msg1, and scheduling msg3;

[0732] This indicates that the signaling is unicast, multicast, or broadcast signaling.

[0733] For example, an A-IoT device learns from the signaling type of the R2D control information that the signaling is used to schedule the "write" function, and thereby determines that the DCI does not contain the second field set, or that the length of the second field set in the DCI is 0.

[0734] For example, if an A-IoT device learns from the signaling type of the R2D control information that the signaling is used to schedule Msg1, it will determine that the second field set of the DCI contains the fields "access type" and "time domain resource allocation", but does not contain the fields "segmented retransmission indication" and "device identifier".

[0735] For example, an A-IoT device determines that the R2D signaling does not contain the second set of fields based on the R2D TBS of the first set of fields, and therefore it is not used to schedule D2R transmissions.
