Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0032] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0033] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto.

[0034] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

The core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). In some embodiments, the core network device 130 may also be an Evolved Packet Core (EPC) device of an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device.

[0044] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0045] 1. Classification of zero-power terminals

[0046] Based on the energy source and usage of zero-power terminals, zero-power terminals can be divided into the following types:

[0047] 1) Passive zero-power terminal

[0048] Zero-power terminals do not require internal batteries. When they approach network devices (such as the reader / writer of a radio frequency identification (RFID) system), they are within the near-field radiation generated by the network device's antenna. Consequently, the zero-power terminal's antenna generates an induced current through electromagnetic induction, which drives the low-power chip circuits in the zero-power terminal to demodulate forward link signals and modulate backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0049] It can be seen that the passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link, and is a true zero-power terminal.

[0050] Passive zero-power terminals do not require batteries, and their RF circuits and baseband circuits are very simple. For example, they do not require low-noise amplifiers (LNAs), power amplifiers (PAs), crystal oscillators, analog-to-digital converters (ADCs), and other devices. Therefore, they have many advantages such as small size, light weight, very low price, and long service life.

[0051] 2) Semi-passive zero-power terminal

[0052] Semi-passive zero-power terminals do not have conventional batteries themselves, but instead use RF energy harvesting modules to harvest radio wave energy and store it in an energy storage unit (such as a capacitor). This energy storage unit then drives the low-power chip circuitry in the zero-power terminal, performing tasks such as demodulating forward link signals and modulating backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.

[0053] It can be seen that the semi-passive zero-power terminal does not require a built-in battery to drive either the forward link or the reverse link. Although energy stored in capacitors is used in operation, the energy comes from the radio energy collected by the energy harvesting module. Therefore, it is also a true zero-power terminal.

[0054] Semi-passive zero-power consumption terminals inherit many advantages of passive zero-power consumption terminals, so they have many advantages such as small size, light weight, very low price, and long service life.

[0055] 3) Active zero-power terminal

[0056] In some scenarios, zero-power terminals can also be active zero-power terminals, which can have built-in batteries. The battery is used to drive the low-power chip circuits in the zero-power terminal, performing tasks such as demodulating forward link signals and modulating reverse link signals. However, for backscatter links, zero-power terminals use backscattering to transmit signals. Therefore, the zero-power nature of these terminals lies primarily in the fact that reverse link signal transmission does not require the terminal's own power, but rather uses backscattering.

[0057] Active zero-power terminals are powered by built-in batteries to extend their communication range and improve communication reliability. Therefore, they are used in scenarios with relatively high requirements for communication distance and read latency.

[0058] 2. Cellular Passive IoT

[0059] As fifth-generation (5G) industry applications expand, the types of connected objects and application scenarios will increase, placing higher demands on the price and power consumption of communication terminals. The application of battery-free, low-cost passive IoT devices has become a key technology for cellular IoT, expanding the types and number of terminals connected to 5G networks and truly realizing the interconnection of everything. Passive IoT devices can be based on existing zero-power devices and expanded upon them for use in cellular IoT.

[0060] 3. Devices based on ambient energy

[0061] In NR and Wi-Fi systems, the battery-free and low-cost nature of devices enables low-cost, large-scale deployment and maintenance-free IoT devices. Research is currently underway to support ambient energy-based IoT devices in NR and Wi-Fi systems. These devices, known as Ambient IoT devices (A-IoT), draw their operating energy from harvested ambient energy sources, such as radio frequency signals, solar energy, thermal energy, and mechanical energy. These devices are similar to passive or semi-passive devices in zero-power communications. A-IoT devices harvest ambient energy and store it in energy storage units. Once the energy storage units have sufficient energy, they drive low-power circuits for forward link signal demodulation and reverse link signal modulation and transmission.

[0062] A research project on A-IoT devices has been carried out in the 3GPP RAN, which roughly divides A-IoT devices into three types: Device A, Device B, and Device C, each with corresponding complexity and communication capabilities.

[0063] Device A: does not have energy storage capabilities and cannot send independent signals, that is, it uses backscatter transmission.

[0064] Device B: It has energy storage capabilities but cannot send independent signals. Instead, it uses backscattering transmission and can use the stored energy to amplify the backscattered signal.

[0065] Device C: has energy storage capabilities and can send independent signals, that is, it has active transmission capabilities.

[0066] Device A has the lowest complexity and power consumption, reaching as low as 1 μW. However, its communication range is limited, typically only a few meters. Device A requires a network device to provide a carrier signal for backscattering transmission. Device C typically has a large capacitor to store energy from the environment, consumes several hundred μW, and can support active signal transmission, thus providing a longer communication range. Because device C can perform active transmission, it does not require a network device to provide a carrier signal. Device B's complexity and power consumption are between those of devices A and C.

[0067] 4. Uplink and sidelink scheduling in NR systems

[0068] In NR, the terminal can send uplink data channels according to the scheduling of the base station. The uplink scheduling information is carried by the uplink downlink control information (DCI). The uplink DCI indicates the time-frequency resources, modulation and coding scheme (MCS), hybrid automatic repeat request (HARQ) process, redundancy version number and other information of the uplink transmission. The terminal sends the uplink data channel on the indicated time-frequency resources in the indicated manner according to the information in the DCI.

[0069] NR V2X supports sideline transmission scheduled by the base station, that is, the first mode resource selection. The first mode resource allocation includes dynamic resource allocation and sideline configuration authorization. The configuration authorization includes type 1 (Type-1) sideline configuration authorization and type 2 (Type-2) sideline configuration authorization. In type 1 sideline configuration authorization, the network configures the sideline configuration authorization transmission resources and transmission parameters for the terminal through Radio Resource Control (RRC) signaling. In type 2 sideline configuration authorization, the network configures some transmission parameters for the terminal through RRC signaling, activates the sideline configuration authorization through DCI signaling, and the DCI is used to configure the sideline transmission resources.

[0070] The dynamic resource allocation mode is a resource allocation mode in which the network dynamically allocates sidelink transmission resources to the terminal through DCI. In the dynamic resource allocation mode, the network allocates sidelink transmission resources to the terminal through DCI, and indicates up to three sidelink transmission resources in one DCI scheduling. The three sidelink transmission resources are used to transmit the same transport block (Transport Block, TB). In addition, the NR-V2X system introduces a physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) to improve the reliability of sidelink transmission. In the NR-V2X dynamic scheduling resource allocation, the base station allocates sidelink transmission resources to the transmitting terminal, and the transmitting terminal sends a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) / physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) to the receiving terminal on the sidelink transmission resources allocated by the network. The receiving terminal sends PSFCH to the transmitting end based on the detection result to indicate whether the PSSCH is received correctly.

[0071] To support dynamic resource allocation, a new DCI format, DCI format 3_0, is introduced in NR-V2X. When used for dynamic resource allocation, the DCI is scrambled with the Sidelink-Radio Network Temporary Identifier (SL-RNTI). In addition, this DCI format can also be used to activate or deactivate a sidelink configuration grant, in which case the DCI is scrambled with the Sidelink-Configured Scheduling-Radio Network Temporary Identifier (SL-CS-RNTI).

[0072] DCI format 3_0 mainly includes the following information:

[0073] 1) Resource pool index:

[0074] NR-V2X supports the network configuration of multiple Mode 1 resource pools. When scheduling sidelink transmission resources through DCI, it is necessary to indicate the resource pool index information in the DCI. The terminal determines which resource pool the sidelink transmission resources scheduled by the DCI belong to based on the resource pool index information.

[0075] 2) Side transmission resource indication information:

[0076] The network can allocate N sideline transmission resources to the terminal for transmitting PSCCH and PSSCH. Where 1≤N≤Nmax, Nmax is 2 or 3, and Nmax is a pre-configured or network-configured parameter. The network device indicates the time domain and frequency domain information of the N sideline transmission resources in the DCI. Specifically, the time-frequency resource information of the N sideline transmission resources is indicated in the DCI through the following information:

[0077] a) Time gap:

[0078] It is used to indicate the time slot interval between the first side transmission resource and the time slot where the DCI is located. The time domain position of the first side transmission resource can be determined based on this information and the time domain position where the terminal receives the DCI. The network configures a table of time intervals through high-level signaling sl-DCI-ToSL-Trans. The elements in the table represent the number of side transmission time slots. The parameter carried in the DCI is an index value. According to the index value and the time interval table, the specific time interval size can be determined. The time slot where the first side transmission resource is located is located in the resource pool and is no earlier than The first time slot at time T DL It is the time corresponding to the starting position of the downlink time slot where the DCI is located, T TA is the current timing advance of the scheduled UE, K SL It is the number of time slots corresponding to the time interval determined by the Time gap information field in the DCI. slot Indicates the duration of the time slot.

[0079] b) Time resource assignment:

[0080] This information field indicates time domain resources in the same manner as SCI format 1-A. This parameter is represented by a Time Resource Indication Value (TRIV) and is used to determine the time slot intervals of the remaining N-1 sideline transmission resources relative to the first sideline transmission resource. Based on the time domain position of the first transmission resource determined above, this information is combined with the time domain position of the remaining N-1 transmission resources to determine the time domain positions.

[0081] c) Lowest index of the subchannel allocation to the initial transmission:

[0082] Used to indicate the lowest index of the subchannel occupied by the first sidelink transmission resource. Since the frequency domain starting positions of PSCCH and PSSCH are aligned, the frequency domain starting positions of PSCCH and PSSCH can be determined based on this information.

[0083] d) Frequency resource allocation:

[0084] The way this information field indicates frequency domain resources is the same as SCI format 1-A. This parameter is represented by the frequency domain resource indicator value (FRIV), which is used to determine the frequency domain resource size of the side transmission resource (i.e., the number of subchannels) and the frequency domain starting position of the other N-1 side transmission resources except the first side transmission resource.

[0085] 3) PUCCH transmission resource indication information:

[0086] The PUCCH transmission resources are used to instruct the terminal to report sidelink HARQ feedback information to the network. In DCI format 3-0, the PUCCH transmission resources are indicated through two information fields.

[0087] 4) HARQ process number:

[0088] Used to indicate the HARQ process number corresponding to the sidelink transmission resources allocated by the network to the terminal.

[0089] 5) New Data Indicator (NDI):

[0090] When the sidelink transmission resources scheduled by DCI format 3-0 are used for new data transmission, the NDI is flipped, otherwise it is not flipped.

[0091] 6) Configuration Index:

[0092] When the terminal is configured with SL-CS-RNTI, DCI format 3_0 can be used to activate or deactivate Type-2 sideline configuration grant. The network can configure multiple parallel Type-2 sideline configuration grants. The index is used to indicate the sideline configuration grant activated or deactivated by the DCI. When the terminal is not configured with SL-CS-RNTI, this information field is 0 bits.

[0093] 7) Counter sidelink assignment index:

[0094] Used to indicate the cumulative number of DCIs sent by the network for scheduling sidelink transmission resources. When the terminal reports sidelink HARQ feedback information to the base station, the number of information bits contained in the generated HARQ-ACK codebook is determined based on this information.

[0095] The above briefly explains the relevant technologies / terms involved in this application, which will not be repeated in the following embodiments.

[0096] Currently, terminal devices can perform uplink or sidelink transmissions based on the scheduling of network equipment (such as base stations). However, in low-power IoT communication scenarios, terminal devices need to send signals to A-IoT devices or receive signals reflected by A-IoT devices. Because the link between terminal devices and A-IoT devices (the A-IoT link) is not an uplink or sidelink, how network equipment should schedule / control terminal devices to communicate with A-IoT devices in low-power IoT communication scenarios remains an unresolved issue.

[0097] In view of this, the present application provides a communication method, apparatus, device, chip, and storage medium. In this method, a first terminal device can send one or more of a carrier, data, or signal to an A-IoT device based on first information from a network device. In other words, the network device can schedule / control communication between the first terminal device and the A-IoT device by sending the first information to the first terminal device.

[0098] Figure 2 is a schematic diagram of a communication scenario applicable to an embodiment of the present application provided in an embodiment of the present application. In Figure 2, the terminal device may be located between the network device and the A-IoT device as an intermediate node (Intermediate Node). Among them, the terminal device may send one or more of a carrier, data, and a signal to the A-IoT device. In some scenarios, the A-IoT device may send a reflected signal to the terminal device based on the carrier sent (provided) by the terminal device, and accordingly, the terminal device may receive the signal reflected by the A-IoT device (that is, the reflected signal sent by the A-IoT device). The reflected signal may, for example, carry data / signals from the A-IoT device, or the reflected signal may not carry data / signals of the A-IoT device.

[0099] Figure 3 is a second schematic diagram of a communication scenario applicable to an embodiment of the present application provided by an embodiment of the present application. In Figure 3, the number of terminal devices (intermediate nodes) may be multiple. For example, in the communication scenario shown in Figure 3, the terminal device may include a first terminal device and a second terminal device. Among them, the first terminal device may send one or more of a carrier, data, and a signal to the A-IoT device. In some scenarios, the A-IoT device may send a reflected signal to the second terminal device based on the carrier sent (provided) by the first terminal device, and accordingly, the second terminal device may receive the signal reflected by the A-IoT device (that is, the reflected signal sent by the A-IoT device). The reflected signal may, for example, carry the data / signal of the A-IoT device, or the reflected signal may not carry the data / signal of the A-IoT device.

[0100] It should be noted that the number of terminal devices in Figure 3 is only exemplary. For example, in some other scenarios, the number of first terminal devices and / or second terminal devices may be multiple, and this embodiment of the application is not limited to this.

[0101] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments.

[0102] FIG4 is a flow chart of a communication method according to an embodiment of the present application. As shown in FIG4 , the method may include the following steps:

[0103] S401, a first terminal device receives first information from a network device, where the first information is used by the first terminal device to send first content to an A-IoT device, where the first content includes one or more of the following: carrier, data, and signal.

[0104] In this embodiment, the network device can send the first information to the first terminal device. Accordingly, the first terminal device can receive the first information. The first information can be used by the first terminal device to send the first sending content to the A-IoT device, or in other words, the first terminal device can send the first sending content to the A-IoT device based on the first information.

[0105] In some embodiments, the method may be applicable to the communication scenario shown in Figure 2. In this communication scenario, the first terminal device may be the terminal device in Figure 2, the network device may send first information to the terminal device (first terminal device) via a Uu link, and the terminal device may send first content to the A-IoT device based on the first information from the network device.

[0106] In some embodiments, the method may be applicable to the communication scenario shown in Figure 3. In this communication scenario, the network device may send first information to the first terminal device via a Uu link between the network device and the first terminal device, and the first terminal device may send first content to the A-IoT device based on the first information from the network device.

[0107] In some embodiments, the first transmission content may include a carrier wave, that is, the first information may be used by the first terminal device to transmit a carrier wave to the A-IoT device. Transmitting a carrier wave may also be understood as transmitting a sinusoidal electromagnetic wave of a specific frequency that does not carry data or signals. In this case, the first information may include one or more of the following:

[0108] First indication information, the first indication information may be used to indicate the frequency of transmitting the carrier, or in other words, the first indication information may be used by the first terminal device to determine the frequency of transmitting the carrier to the A-IoT device;

[0109] Second indication information, the second indication information may be used to indicate a time for sending a carrier wave, or in other words, the second indication information may be used by the first terminal device to determine a time for sending a carrier wave to the A-IoT device;

[0110] The third indication information can be used to indicate the power of the transmitted carrier, or in other words, the third indication information can be used by the first terminal device to determine the power of the carrier sent to the A-IoT device.

[0111] That is to say, the first information can be used to indicate to the first terminal device one or more of the frequency, time, and power of sending the carrier, so that the first terminal device can send the carrier to the A-IoT device according to the instructions of the first information.

[0112] In some embodiments, the first indication information may include (or indicate): one or more frequencies of the transmitting carrier; and / or one or more indexes corresponding to the one or more frequencies of the transmitting carrier.

[0113] In one example, the first indication information may include: one or more frequencies of the transmitting carrier.

[0114] For example, the first indication information may include a frequency for sending a carrier. In this case, the first terminal device may use this frequency to send a carrier to the A-IoT device, or in other words, the first terminal device may send a carrier to the A-IoT device at this frequency, or in other words, the first terminal device may send a carrier of this frequency to the A-IoT device.

[0115] For another example, the first indication information may include multiple frequencies for sending carriers. In this case, the first terminal device may use the multiple frequencies to send carriers to the A-IoT device, or in other words, the first terminal device may send carriers to the A-IoT device at the multiple frequencies, or in other words, the first terminal device may send carriers of the multiple different frequencies to the A-IoT device.

[0116] In one example, the first indication information may include: one or more indexes corresponding to one or more frequencies of the transmitting carrier.

[0117] For example, the first indication information may include an index corresponding to a frequency of the transmitted carrier. In this case, the first terminal device can determine a frequency of the transmitted carrier based on the index, and then use the frequency to send the carrier to the A-IoT device.

[0118] For another example, the first indication information may include: indexes corresponding to multiple frequencies for transmitting carrier waves. The multiple frequencies may correspond to the same index, or the multiple frequencies may correspond one-to-one to multiple indexes. In this case, the first terminal device may determine the multiple frequencies for transmitting carrier waves based on the indexes corresponding to the multiple frequencies, and may then use the multiple frequencies to transmit carrier waves to the A-IoT device.

[0119] In some embodiments, the correspondence between the one or more frequencies of the transmitting carrier and the one or more indexes may be indicated by Radio Resource Control (RRC) signaling sent by a network device.

[0120] In some embodiments, the number of frequencies of the transmission carriers indicated by the first indication information is related to the capability of the first terminal device. For example, the network device may determine / decide the number of frequencies of the transmission carriers indicated by the first indication information based on the capability report of the terminal device.

[0121] According to the method of this embodiment, the first terminal device can determine one or more frequencies for sending a carrier based on the first indication information, and then use the one or more frequencies to send a carrier to the A-IoT device.

[0122] In some embodiments, the second indication information may include indication information for indicating one or more of the following:

[0123] The moment when the carrier wave starts to be transmitted;

[0124] The index corresponding to the time when the carrier starts to be transmitted (for example, recorded as the first index);

[0125] The duration of the carrier transmission;

[0126] The time domain position of the first resource of the transmitting carrier (that is, the time domain position of the first resource used to transmit the carrier);

[0127] The number of resources for transmitting carriers (ie, the number of resources used for transmitting carriers).

[0128] In some embodiments, the time at which carrier transmission begins is related to the second time interval and the time slot in which the first information is located. For example, the second time interval is the time interval between the time at which carrier transmission begins and the start or end of the time slot in which the first information is located. The second time interval may be included in the second indication information, so that the first terminal device can determine the time at which carrier transmission begins based on the second time interval and the time slot in which the first information is located. In other words, the network device can indicate the time at which carrier transmission begins to be transmitted to the first terminal device by indicating the second time interval to the first terminal device.

[0129] Exemplarily, the moment of starting to send the carrier can be, for example, the starting point of a time slot, or the starting point of an orthogonal frequency division multiplexing (OFDM) symbol, or the starting point of a subframe. Accordingly, the granularity of the second time interval can be a time slot, an OFDM symbol or a subframe.

[0130] In some embodiments, the correspondence between the time when the carrier starts to be transmitted and the first index may be indicated by RRC signaling sent by the network device.

[0131] In some embodiments, the duration of the transmission carrier may be expressed as, for example, the number of consecutive uplink time slots, or the number of consecutive uplink OFDM symbols, or the number of consecutive uplink subframes.

[0132] In some embodiments, the second indication information may include indication information for indicating the following: the moment when the carrier is started to be sent, and the duration of the carrier being sent. In this case, the moment when the carrier is started to be sent and the duration of the carrier being sent may be indicated by joint coding. For example, the second indication information may include a start and length indicator value (SLIV), or the second indication information may be a SLIV, which may be used to jointly indicate the moment when the carrier is started to be sent and the duration of the carrier being sent, and the SLIV may uniquely correspond to a start value (the moment when the carrier is started to be sent) and a length value (the duration of the carrier being sent).

[0133] In some embodiments, the second indication information may include indication information for indicating the following: the time domain position of the first resource of the sending carrier (such as the starting position of the first resource in the time domain), the number of resources of the sending carrier. In this case, the time domain position of the first resource of the sending carrier and the number of resources of the sending carrier may be indicated by joint coding. For example, the second indication information may include SLIV, or the second indication information may be SLIV, which may be used to jointly indicate the time domain position of the first resource of the sending carrier and the number of resources of the sending carrier, and the SLIV may uniquely correspond to a starting point value (the time domain position of the first resource of the sending carrier) and a length value (the number of resources of the sending carrier).

[0134] In this embodiment, a resource may be a time unit, which may be, for example, a time range corresponding to one or more consecutive OFDM symbols, or one or more consecutive time slots, or one or more consecutive subframes.

[0135] In some embodiments, the second indication information may not include indication information for indicating the duration of the transmission carrier, or in other words, the second indication information may not indicate the duration of the transmission carrier. In some embodiments, the duration of the transmission carrier may be configured by the network device, or may be predefined (such as a standard definition). As an implementation method, the duration of the transmission carrier configured or predefined by the network device may be, for example, the duration corresponding to one transmission resource. In this way, if the duration of the transmission carrier is not indicated in the second indication information, the first terminal device may deem the duration of the transmission carrier to be the duration corresponding to one transmission resource.

[0136] In some embodiments, the second indication information may not include indication information for indicating the number of resources for sending carriers, or in other words, the second indication information may not indicate the number of resources for sending carriers. In some embodiments, the number of resources for sending carriers may be configured by a network device, or may be predefined (such as a standard definition). As an implementation method, the number of resources for sending carriers configured or predefined by a network device may be, for example, 1. In this way, if the number of resources for sending carriers is not indicated in the second indication information, the first terminal device may deem that the number of resources for sending carriers is 1.

[0137] According to the method of this embodiment, the first terminal device can determine the time to send the carrier based on the second indication information, and then send the carrier to the A-IoT device at this time.

[0138] In some embodiments, the third indication information may include one or more of the following, or in other words, the third indication information may indicate one or more of the following:

[0139] The power of the transmitted carrier;

[0140] The power range of the transmitted carrier;

[0141] An index corresponding to the power of the transmitted carrier (e.g., recorded as a second index);

[0142] An index corresponding to the power range of the transmitted carrier (e.g., recorded as the third index);

[0143] Relative to the first adjustment value of the reference transmit power, the power of the transmit carrier is related to the first adjustment value.

[0144] In some embodiments, the correspondence between the power of the transmitted carrier and the second index may be indicated by RRC signaling sent by the network device. In some embodiments, the correspondence between the power range of the transmitted carrier and the third index may be indicated by RRC signaling sent by the network device.

[0145] In some embodiments, the reference transmit power may be, for example, the transmit power last used by the first terminal device (e.g., the transmit power of the last carrier, data, or signal). In this way, the first terminal device may determine the power of the carrier to be transmitted this time based on the reference transmit power (e.g., the transmit power last used) and the first adjustment value, and may then send the carrier to the A-IoT device based on the power.

[0146] In some embodiments, the first information may not include the third indication information, or in other words, the first information may not indicate the power of the transmitting carrier. In some embodiments, when the first information does not include the third indication information, the power of the transmitting carrier used by the first terminal device may be the same as the current uplink transmit power, or may be the currently allowed maximum transmit power.

[0147] According to the method of this embodiment, the first terminal device can determine the power of the transmitted carrier based on the third indication information, and then can send the carrier to the A-IoT device based on the power.

[0148] In some embodiments, the first transmission content may include data or signals, that is, the first information may be used by the first terminal device to send data or signals to the A-IoT device. In this case, the first information may include one or more of the following:

[0149] Fourth indication information: The fourth indication information may be used to indicate a frequency for sending data or signals, or in other words, the fourth indication information may be used by the first terminal device to determine a frequency for sending data or signals to the A-IoT device;

[0150] The fifth indication information may be used to indicate the time for sending data or signals, or in other words, the fifth indication information may be used by the first terminal device to determine the time for sending data or signals to the A-IoT device;

[0151] Sixth indication information: The sixth indication information may be used to indicate the power of sending data or signals, or in other words, the sixth indication information may be used by the first terminal device to determine the power of sending data or signals to the A-IoT device;

[0152] A-IoT device identification (ID).

[0153] That is, the first information can be used to indicate to the first terminal device one or more of the frequency of sending data or signals, the time of sending data or signals, the power of sending data or signals, and the identification of the A-IoT device, so that the first terminal device can send data or signals to the A-IoT device according to the instruction of the first information. The frequency of sending data or signals can also be understood as the frequency of the carrier used to send data or signals.

[0154] In some embodiments, the number of A-IoT device identifiers may be one or more. In the case where the first information includes the identifier of one A-IoT device, the first terminal device may send data or signals to the A-IoT device based on the identifier; in the case where the first information includes the identifiers of multiple A-IoT devices, the first terminal device may send data or signals to the multiple A-IoT devices based on the identifiers of the multiple A-IoT devices included in the first signal. In some embodiments, the first information may not include the identifier of the A-IoT device. In this case, the first terminal device may determine to which A-IoT device or devices the data or signals are to be sent.

[0155] In some embodiments, the fourth indication information may include (or indicate): one or more frequencies for transmitting data or signals; and / or one or more indexes corresponding to the one or more frequencies for transmitting data or signals.

[0156] In one example, the fourth indication information may include: one or more frequencies for sending data or signals.

[0157] For example, the fourth indication information may include a frequency for sending data or signals. In this case, the first terminal device may use this frequency to send data or signals to the A-IoT device, or in other words, the first terminal device may send data or signals to the A-IoT device at this frequency.

[0158] For another example, the fourth indication information may include multiple frequencies for sending data or signals. In this case, the first terminal device may use the multiple frequencies to send data or signals to the A-IoT device, or in other words, the first terminal device may send data or signals to the A-IoT device on the multiple frequencies.

[0159] In one example, the fourth indication information may include: one or more indexes corresponding to one or more frequencies for sending data or signals.

[0160] For example, the fourth indication information may include an index corresponding to a frequency for sending data or signals. In this case, the first terminal device can determine a frequency for sending data or signals based on the index, and then use the frequency to send data or signals to the A-IoT device, or in other words, send data or signals to the A-IoT device at the frequency.

[0161] For another example, the fourth indication information may include: indexes corresponding to multiple frequencies for sending data or signals. The multiple frequencies may correspond to the same index, or the multiple frequencies may correspond one-to-one to multiple indexes. In this case, the first terminal device may determine the multiple frequencies for sending data or signals based on the indexes corresponding to the multiple frequencies, and then use the multiple frequencies to send data or signals to the A-IoT device, or in other words, send data or signals to the A-IoT device on the multiple frequencies.

[0162] In some embodiments, the correspondence between one or more frequencies for sending data or signals and the one or more indexes may be indicated by RRC signaling sent by the network device.

[0163] In some embodiments, the number of frequencies for sending data or signals indicated by the fourth indication information is related to the capability of the first terminal device. For example, the network device may determine / decide the number of frequencies for sending data or signals indicated by the fourth indication information based on the capability reported by the terminal device.

[0164] According to the method of this embodiment, the first terminal device can determine one or more frequencies for sending data or signals based on the fourth indication information, and then use the one or more frequencies to send data or signals to the A-IoT device.

[0165] In some embodiments, the fifth indication information includes indication information for indicating one or more of the following:

[0166] The moment when data or signal transmission begins;

[0167] The index corresponding to the time when data or signal transmission starts (for example, recorded as the fourth index);

[0168] the duration of the data or signal being sent;

[0169] The time domain position of the first resource for transmitting data or a signal (that is, the time domain position of the first resource used for transmitting data or a signal);

[0170] The number of resources for sending data or signals (that is, the number of resources used to send data or signals).

[0171] In some embodiments, the time at which data or signal transmission begins is related to a third time interval and the time slot in which the first information is located. For example, the third time interval is the time interval between the time at which data or signal transmission begins and the start or end point of the time slot in which the first information is located. The third time interval may be included in the fifth indication information. In this way, the first terminal device may determine the time at which data or signal transmission begins based on the third time interval and the time slot in which the first information is located. In other words, the network device may indicate the time at which data or signal transmission begins by indicating the third time interval to the first terminal device.

[0172] Exemplarily, the moment of starting to send data or signal can be, for example, the starting point of a time slot, or the starting point of a certain OFDM symbol, or the starting point of a certain subframe. Accordingly, the granularity of the third time interval can be a time slot, an OFDM symbol or a subframe.

[0173] In some embodiments, the correspondence between the time when data or signal transmission starts and the fourth index may be indicated by RRC signaling sent by the network device.

[0174] In some embodiments, the duration of sending data or signals may be expressed as, for example, the number of consecutive uplink time slots, or the number of consecutive uplink OFDM symbols, or the number of consecutive uplink subframes.

[0175] In some embodiments, the fifth indication information may include indication information for indicating the following: the moment when data or signal transmission starts, and the duration of transmitting the data or signal. In this case, the moment when data or signal transmission starts and the duration of transmitting the data or signal may be indicated by joint coding. For example, the fifth indication information may include SLIV, or the fifth indication information may be SLIV, which may be used to jointly indicate the moment when data or signal transmission starts and the duration of transmitting the data or signal, and the SLIV may uniquely correspond to a starting point value (the moment when data or signal transmission starts) and a length value (the duration of transmitting the data or signal).

[0176] In some embodiments, the fifth indication information may include indication information for indicating the following: the time domain position of the first resource for sending data or signals (such as the starting position of the first resource in the time domain), the number of resources for sending data or signals. In this case, the time domain position of the first resource for sending data or signals and the number of resources for sending data or signals may be indicated by joint coding. For example, the fifth indication information may include SLIV, or the fifth indication information may be SLIV, which may be used to jointly indicate the time domain position of the first resource for sending data or signals and the number of resources for sending data or signals, and the SLIV may uniquely correspond to a starting value (the time domain position of the first resource for sending data or signals) and a length value (the number of resources for sending data or signals).

[0177] According to the method of this embodiment, the first terminal device can determine the time to send data or signals based on the fifth indication information, and then send data or signals to the A-IoT device at that time.

[0178] In some embodiments, the sixth indication information may include one or more of the following:

[0179] The power of the transmitted data or signal;

[0180] The power range for transmitting data or signals;

[0181] an index corresponding to the power of the transmitted data or signal (e.g., recorded as the fifth index);

[0182] An index corresponding to a power range for transmitting data or signals (e.g., recorded as the sixth index);

[0183] The power of the transmitted data or signal is related to the second adjustment value relative to the second adjustment value of the reference transmit power.

[0184] In some embodiments, the correspondence between the power of the transmitted data or signal and the fifth index may be indicated by RRC signaling sent by the network device. In some embodiments, the correspondence between the power range of the transmitted data or signal and the sixth index may be indicated by RRC signaling sent by the network device.

[0185] In some embodiments, the reference transmit power may be, for example, the transmit power last used by the first terminal device (e.g., the transmit power last used to transmit a carrier, data, or signal). In this way, the first terminal device may determine the power of the data or signal to be transmitted this time based on the reference transmit power (e.g., the transmit power last used) and the second adjustment value, and may then send data or signals to the A-IoT device based on the power.

[0186] In some embodiments, the first information may not include the sixth indication information, or in other words, the first information may not indicate the power of sending data or signals. In some embodiments, when the first information does not include the sixth indication information, the power used by the first terminal device to send data or signals may be, for example, the same as the current uplink transmit power, or may be the currently allowed maximum transmit power.

[0187] According to the method of this embodiment, the first terminal device can determine the power of sending data or signals based on the sixth indication information, and then send data or signals to the A-IoT device based on the power.

[0188] In some embodiments, the first transmission content includes data or signals and also includes a carrier wave. That is, the first information can be used by the first terminal device to send data or signals to the A-IoT device, and can also be used by the first terminal device to send a carrier wave to the A-IoT device. In this case, the first information can include one or more of the fourth indication information, the fifth indication information, the sixth indication information, and the identifier of the A-IoT device, and can also include one or more of the first indication information, the second indication information, and the third indication information.

[0189] In some embodiments, the time of sending data or signals is before the time of sending carrier waves. That is, the first terminal device can send data or signals to the A-IoT device first, and then send carrier waves to the A-IoT device in chronological order. For this scenario, the following situations may exist:

[0190] Case 1: the first information includes the fourth indication information but does not include the first indication information.

[0191] In this case, the frequency of the transmitted carrier is the same as the frequency of the transmitted data or signal. That is, if the first information does not include the first indication information, or in other words, the first information does not indicate the frequency of the transmitted carrier, the first terminal device may use the frequency of the transmitted data or signal indicated by the fourth indication information as the frequency of the transmitted carrier.

[0192] Case 2: the first information includes the fifth indication information but does not include the second indication information.

[0193] In this case, the time interval between the time when the carrier is sent and the time when the data or signal is sent is the first time interval, which can be predefined or configured by the network device. In other words, if the first information does not include the second indication information, or in other words, the first information does not indicate the time when the carrier is sent, then after the first terminal device sends the data or signal, it can send the carrier to the A-IoT device after the first time interval has passed. In other words, the first terminal device can send the carrier to the A-IoT device after the first time interval has passed after sending the data or signal.

[0194] Case 3: the first information includes the sixth indication information but does not include the third indication information.

[0195] In this case, the power of the transmitted carrier is the same as the power of the transmitted data or signal. That is, if the first information does not include the third indication information, or in other words, the first information does not indicate the power of the transmitted carrier, the first terminal device may use the power of the transmitted data or signal indicated by the sixth indication information as the frequency of the transmitted carrier.

[0196] In some embodiments, the first transmitted content includes data or a signal and also includes a carrier wave, and the time of transmitting the data or the signal is before the time of transmitting the carrier wave. In this case, the first information may include one or more of the fourth indication information, the fifth indication information, the sixth indication information, and the identifier of the A-IoT device.

[0197] In some embodiments, the frequency of sending the carrier is the same as the frequency of sending the data or signal; the time interval between the time of sending the carrier and the time of sending the data or signal is a first time interval, and the first time interval can be predefined or configured by the network device; the power of sending the carrier is the same as the power of sending the data or signal.

[0198] That is, if the first information includes the fourth indication information, or if the first information indicates the frequency of sending data or signals, the first terminal device may use the frequency of sending data or signals as the frequency of sending carrier waves. If the first information includes the fifth indication information, or if the first information indicates the time of sending data or signals, the first terminal device may send carrier waves to the A-IoT device after the first time interval of sending data or signals. If the first information includes the sixth indication information, or if the first information indicates the power of sending data or signals, the first terminal device may use the power of sending data or signals as the frequency of sending carrier waves.

[0199] According to the method of this embodiment, one or more of the fourth indication information, the fifth indication information, and the sixth indication information can be used as an indication of sending data or signals (or in other words, can be used to send data or signals), and can also be used as an indication of sending a carrier (or in other words, can be used to send a carrier), which is beneficial to reducing signaling overhead.

[0200] In some embodiments, the frequency at which data or signals are transmitted is different from the frequency at which the carrier is transmitted. That is, the first terminal device may transmit the carrier and data / signals to the A-IoT device at different frequencies. For this scenario, the following situations may exist:

[0201] Case 1: the first information includes the second indication information but does not include the fifth indication information.

[0202] In this case, the time when the data or signal is sent is the same as the time when the carrier is sent. That is, if the first information does not include the fifth indication information, or in other words, the first information does not indicate the time when the data or signal is sent, the first terminal device may use the time when the carrier is sent indicated by the second indication information as the time when the data or signal is sent.

[0203] Case 2: the first information includes the fifth indication information but does not include the second indication information.

[0204] In this case, the time for transmitting the carrier wave is the same as the time for transmitting the data or signal. That is, if the first information does not include the second indication information, or in other words, the first information does not indicate the time for transmitting the carrier wave, the first terminal device may use the time for transmitting the data or signal indicated by the fifth indication information as the time for transmitting the carrier wave.

[0205] Case 3: the first information includes three indication information but does not include the sixth indication information.

[0206] In this case, the power of the transmitted data or signal is the same as the power of the transmitted carrier. That is, if the first information does not include the sixth indication information, or in other words, the first information does not indicate the power of the transmitted data or signal, the first terminal device may use the power of the transmitted carrier indicated by the third indication information as the power of the transmitted data or signal.

[0207] Case 4: the first information includes the sixth indication information but does not include the third indication information.

[0208] In this case, the power of the transmitted carrier is the same as the power of the transmitted data or signal. That is, if the first information does not include the third indication information, or in other words, the first information does not indicate the power of the transmitted carrier, the first terminal device may use the power of the transmitted data or signal indicated by the sixth indication information as the frequency of the transmitted carrier.

[0209] In some embodiments, the first transmission content may be determined by the first terminal device. That is, after receiving the first information from the network device, the first terminal device may use the first information to transmit the first transmission content determined / determined by the first terminal device. For example, if the first transmission content determined by the first terminal device is a carrier, the first terminal device may use the first information to transmit the carrier; for another example, if the first transmission content determined by the first terminal device is data or a signal, the first terminal device may use the first information to transmit the data or signal. In this case, the first information may include one or more of the following:

[0210] Seventh indication information, the seventh indication information may be used to indicate a frequency of sending the first sent content, or in other words, the seventh indication information may be used by the first terminal device to determine a frequency of sending the first sent content to the A-IoT device;

[0211] Eighth indication information, the eighth indication information may be used to indicate the time of sending the first sent content, or in other words, the eighth indication information may be used by the first terminal device to determine the time of sending the first sent content to the A-IoT device;

[0212] The ninth indication information can be used to indicate the power of sending the first sending content, or in other words, the ninth indication information can be used by the first terminal device to determine the power of sending the first sending content to the A-IoT device.

[0213] In some embodiments, the seventh indication information may include (or indicate): one or more frequencies for sending the first content; and / or one or more indexes corresponding to the one or more frequencies for sending the first content.

[0214] In one example, the seventh indication information may include: one or more frequencies for sending the first sent content.

[0215] For example, the seventh indication information may include a frequency for sending the first sending content. In this case, the first terminal device may use the frequency to send the first sending content to the A-IoT device, or the first terminal device may send the first sending content to the A-IoT device at the frequency.

[0216] For another example, the seventh indication information may include multiple frequencies for sending the first sending content. In this case, the first terminal device may use the multiple frequencies to send the first sending content to the A-IoT device, or the first terminal device may send the first sending content to the A-IoT device on the multiple frequencies.

[0217] In one example, the seventh indication information may include: one or more indexes corresponding to one or more frequencies of sending the first sent content.

[0218] For example, the seventh indication information may include an index corresponding to a frequency for sending the first content. In this case, the first terminal device can determine a frequency for sending the first content based on the index, and then use the frequency to send the first content to the A-IoT device.

[0219] For another example, the seventh indication information may include: indexes corresponding to multiple frequencies for sending the first content. The multiple frequencies may correspond to the same index, or the multiple frequencies may correspond one-to-one to multiple indexes. In this case, the first terminal device may determine the multiple frequencies for sending the first content based on the indexes corresponding to the multiple frequencies, and may then use the multiple frequencies to send the first content to the A-IoT device.

[0220] In some embodiments, the correspondence between the one or more frequencies for sending the first sent content and the one or more indexes may be indicated by RRC signaling sent by the network device.

[0221] In some embodiments, the number of frequencies for sending the first content indicated by the seventh indication information is related to the capability of the first terminal device. For example, the network device may determine / decide the number of frequencies for sending the first content indicated by the seventh indication information based on the capability reported by the terminal device.

[0222] According to the method of this embodiment, the first terminal device can determine one or more frequencies for sending the first sending content based on the seventh indication information, and then use the one or more frequencies to send the first sending content determined by the first terminal device to the A-IoT device.

[0223] In some embodiments, the eighth indication information may include indication information for indicating one or more of the following:

[0224] The moment when the first content to be sent begins to be sent;

[0225] The index corresponding to the time when the first content is started to be sent (for example, recorded as the seventh index);

[0226] The duration of sending the first sent content;

[0227] Sending a time domain location of a first resource of the first sent content (that is, a time domain location of the first resource used to send the first sent content);

[0228] The number of resources for sending the first content (ie, the number of resources used to send the first content).

[0229] In some embodiments, the time at which the first content to be transmitted begins is related to a fourth time interval and the time slot in which the first information is located. For example, the fourth time interval is the time interval between the time at which the first content to be transmitted begins and the start or end of the time slot in which the first information is located. The fourth time interval may be included in the eighth indication information, so that the first terminal device can determine the time at which the first content to be transmitted begins based on the fourth time interval and the time slot in which the first information is located. In other words, the network device can indicate to the first terminal device the time at which the first content to be transmitted begins by indicating the fourth time interval to the first terminal device.

[0230] Exemplarily, the moment of starting to send the first content may be, for example, the starting point of a time slot, or the starting point of a certain OFDM symbol, or the starting point of a certain subframe. Accordingly, the granularity of the fourth time interval may be a time slot, an OFDM symbol or a subframe.

[0231] In some embodiments, the correspondence between the time when the first transmission content starts to be sent and the seventh index can be indicated by RRC signaling sent by the network device.

[0232] In some embodiments, the duration of sending the first transmission content may be expressed as, for example, the number of consecutive uplink time slots, or the number of consecutive uplink OFDM symbols, or the number of consecutive uplink subframes.

[0233] In some embodiments, the eighth indication information may include indication information for indicating the following: the moment when the first content to be sent is started, and the duration of sending the first content to be sent. In this case, the moment when the first content to be sent is started and the duration of sending the first content to be sent may be indicated by joint coding. For example, the eighth indication information may include SLIV, or the eighth indication information may be SLIV, which may be used to jointly indicate the moment when the first content to be sent is started and the duration of sending the first content to be sent, and the SLIV may uniquely correspond to a starting point value (the moment when the first content to be sent is started) and a length value (the duration of sending the first content to be sent).

[0234] In some embodiments, the eighth indication information may include indication information for indicating the following: the time domain position of the first resource for sending the first content to be sent (such as the starting position of the first resource in the time domain), and the number of resources for sending the first content to be sent. In this case, the time domain position of the first resource for sending the first content to be sent and the number of resources for sending the first content to be sent may be indicated by joint coding. For example, the eighth indication information may include SLIV, or the eighth indication information may be SLIV, which may be used to jointly indicate the time domain position of the first resource for sending the first content to be sent and the number of resources for sending the first content to be sent, and the SLIV may uniquely correspond to a starting point value (the time domain position of the first resource for sending the first content to be sent) and a length value (the number of resources for sending the first content to be sent).

[0235] According to the method of this embodiment, the first terminal device can determine the time to send the first content based on the eighth indication information, and then send the first content determined by the first terminal device to the A-IoT device at this time.

[0236] In some embodiments, the ninth indication information may include one or more of the following:

[0237] power for transmitting the first transmission content;

[0238] a power range for sending the first transmission content;

[0239] an index corresponding to the power for sending the first sent content (for example, recorded as the eighth index);

[0240] Sending an index corresponding to the power range of the first transmission content (for example, recorded as the ninth index);

[0241] The power at which the first transmission content is transmitted is related to the third adjustment value relative to the third adjustment value of the reference transmission power.

[0242] In some embodiments, the correspondence between the power of sending the first transmission content and the eighth index can be indicated by RRC signaling sent by the network device. In some embodiments, the correspondence between the power range of sending the first transmission content and the ninth index can be indicated by RRC signaling sent by the network device.

[0243] In some embodiments, the reference transmit power may be, for example, the transmit power last used by the first terminal device (e.g., the transmit power last used to transmit a carrier, data, or signal). In this way, the first terminal device may determine the power for transmitting the first transmission content this time based on the reference transmit power (e.g., the transmit power last used) and the third adjustment value, and may then send the first transmission content to the A-IoT device based on the power.

[0244] In some embodiments, the first information may not include the ninth indication information, or in other words, the first information may not indicate the power for sending the first transmission content. In some embodiments, when the first information does not include the ninth indication information, the power used by the first terminal device to send the first transmission content may be the same as the current uplink transmission power, or may be the currently allowed maximum transmission power.

[0245] According to the method of this embodiment, the first terminal device can determine the power for sending the first sending content based on the ninth indication information, and then can send the first sending content determined by the first terminal device to the A-IoT device based on the power.

[0246] In some embodiments, the first information may be DCI (eg, noted as first DCI).

[0247] In some embodiments, the number of bits of the first DCI may be the same as the number of bits of the second DCI currently configured by the first terminal device, and the first DCI and the second DCI may be scrambled by different Radio Network Temporary Identifiers (RNTIs). The second DCI may be, for example, an uplink DCI, a downlink DCI, or a sidelink DCI.

[0248] In some embodiments, the number of bits of the first DCI may be configured by the network device. If the number of bits contained in all bit fields in the first DCI is less than the number of bits configured by the network device, zeros may be padded at the end of the first DCI.

[0249] In some embodiments, the first information may be configuration authorization.

[0250] In some embodiments, when the first information is a configuration authorization, the first information may further include: tenth indication information, which is used to indicate a repetition period in the time domain of the resource for sending the first content. In this way, the first terminal device may send the first content to the A-IoT device based on the repetition period.

[0251] According to the method of this embodiment, the first terminal device can send first transmission content (including one or more of carrier, data, and signal) to the A-IoT device based on the first information from the network device. In other words, the network device can schedule / control the communication between the first terminal device and the A-IoT device by sending the first information to the first terminal device.

[0252] FIG5 is a second flow chart of a communication method according to an embodiment of the present application. As shown in FIG5 , the method may include the following steps:

[0253] S501, a second terminal device receives second information from a network device, where the second information is used by the second terminal device to receive a reflected signal from an A-IoT device.

[0254] In this embodiment, the network device may send second information to the second terminal device, and accordingly, the second terminal device may receive the second information. The second information may be used by the second terminal device to receive the reflected signal from the A-IoT device, or in other words, the second terminal device may receive the reflected signal from the A-IoT device based on the second information.

[0255] In some embodiments, the method may be applicable to the communication scenario shown in Figure 3. In this communication scenario, the network device may send the second information to the second terminal device via the Uu link between the network device and the second terminal device, and the second terminal device may receive the reflected signal from the A-IoT device based on the second information from the network device. In some embodiments, the network device may also send the first information to the first terminal device via the Uu link between the network device and the first terminal device. The first information can be used by the first terminal device to send the first transmission content (for example, it may include one or more of the carrier, data, and signal) to the A-IoT device, or the first terminal device may send the first transmission content to the A-IoT device based on the first information. Among them, the implementation method of the first terminal device sending the first transmission content to the A-IoT device based on the first information can refer to the method shown in Figure 4, which will not be repeated here.

[0256] In some embodiments, the second information may include:

[0257] First indication information, where the first indication information may be used to indicate a frequency at which the first terminal device sends a carrier wave; and / or,

[0258] The second indication information can be used to indicate the time when the first terminal device sends the carrier.

[0259] Among them, the carrier wave (a sinusoidal electromagnetic wave of a certain frequency that does not carry data and signals) sent by the first terminal device can be used by the A-IoT device to send a reflected signal to the second terminal device. For example, in the communication scenario shown in Figure 3, the first terminal device can send (provide) a carrier wave to the A-IoT device based on the first information, so that the A-IoT device can use the carrier wave provided by the first terminal device to send a reflected signal to the second terminal device. In one possible scenario, the A-IoT device can modulate the carrier wave provided by the first terminal device so that the carrier wave carries data or signals, and then the A-IoT device can send the carrier wave carrying data or signals to the second terminal device by reflection. In this case, the reflected signal sent by the A-IoT device is the carrier wave carrying data or signals. In another possible scenario, the reflected signal sent by the A-IoT device may not carry data or signals. For example, the reflected signal can be used only for measurement.

[0260] In some embodiments, the first indication information may include (or indicate): one or more frequencies of the carrier sent by the first terminal device; and / or one or more indexes corresponding to the one or more frequencies of the carrier sent by the first terminal device.

[0261] In one example, the first indication information may include: one or more frequencies of the carrier transmitted by the first terminal device.

[0262] For example, the first indication information may include a frequency at which the first terminal device transmits a carrier wave. In this case, the second terminal device may receive a reflected signal from the A-IoT device at this frequency.

[0263] For another example, the first indication information may include multiple frequencies at which the first terminal device sends a carrier. In this case, the second terminal device may receive reflected signals from the A-IoT device at the multiple frequencies.

[0264] In one example, the first indication information may include: one or more indexes corresponding to one or more frequencies of the carrier transmitted by the first terminal device.

[0265] For example, the first indication information may include an index corresponding to a frequency at which the first terminal device sends a carrier. In this case, the second terminal device can determine a frequency at which the first terminal device sends a carrier based on the index, and then receive the reflected signal from the A-IoT device at this frequency.

[0266] For another example, the first indication information may include the indices corresponding to multiple frequencies of the carrier transmitted by the first terminal device. The multiple frequencies may correspond to the same index, or the multiple frequencies may correspond one-to-one to multiple indices. In this case, the second terminal device may determine the multiple frequencies of the carrier transmitted by the first terminal device based on the indices corresponding to the multiple frequencies, and may then receive reflected signals from the A-IoT device on the multiple frequencies.

[0267] In some embodiments, the correspondence between one or more frequencies of the carrier sent by the first terminal device and the one or more indexes can be indicated by RRC signaling sent by the network device.

[0268] According to the method of this embodiment, the second terminal device can determine one or more frequencies of the carrier transmitted by the first terminal device based on the first indication information, and then can receive the reflected signal from the A-IoT device at the one or more frequencies.

[0269] It can be understood that since the carrier sent by the first terminal device is used for the A-IoT device to send a reflected signal, or in other words, the reflected signal sent by the A-IoT device is sent by reflecting the carrier sent by the first terminal device, the frequency of the carrier sent by the first terminal device can be used as the frequency of the second terminal device receiving the reflected signal from the A-IoT device.

[0270] In some embodiments, the second indication information may include indication information for indicating one or more of the following:

[0271] The moment when the first terminal device starts transmitting the carrier wave;

[0272] An index corresponding to the moment when the first terminal device starts transmitting the carrier (for example, recorded as the first index);

[0273] The duration of the carrier transmission by the first terminal device;

[0274] The time domain position of the first resource of the carrier transmitted by the first terminal device (that is, the time domain position of the first resource used for the first terminal device to transmit the carrier);

[0275] The number of resources for the first terminal device to send carriers (that is, the number of resources used for the first terminal device to send carriers).

[0276] In some embodiments, the moment when the first terminal device starts sending the carrier is related to the second time interval and the time slot where the second information is located. For example, the second time interval is the time interval between the moment when the first terminal device starts sending the carrier and the start or end point of the time slot where the second information is located. The second time interval may be included in the second indication information, so that the second terminal device can determine the moment when the first terminal device starts sending the carrier based on the second time interval and the time slot where the second information is located. Furthermore, the second terminal device can determine the moment when it starts receiving the reflected signal from the A-IoT device based on the moment when the first terminal device starts sending the carrier. In one possible way, the moment when the first terminal device starts sending the carrier is the moment when the second terminal device starts receiving the reflected signal.

[0277] In some embodiments, the correspondence between the moment when the first terminal device starts sending the carrier and the first index can be indicated by RRC signaling sent by the network device.

[0278] In some embodiments, the second indication information may include indication information for indicating the following: the moment when the first terminal device starts to send the carrier, and the duration of the first terminal device sending the carrier. In this case, the moment when the first terminal device starts to send the carrier and the duration of the first terminal device sending the carrier may be indicated by joint coding. For example, the second indication information may include SLIV, or the second indication information may be SLIV, which may be used to jointly indicate the moment when the carrier starts to be sent and the duration of the carrier being sent, and the SLIV may uniquely correspond to a starting point value (the moment when the first terminal device starts to send the carrier) and a length value (the duration of the first terminal device sending the carrier).

[0279] In some embodiments, the second indication information may include indication information for indicating the following: the time domain position of the first resource of the carrier sent by the first terminal device (such as the starting position of the first resource in the time domain), and the number of resources of the carrier sent by the first terminal device. In this case, the time domain position of the first resource of the carrier sent by the first terminal device and the number of resources of the carrier sent by the first terminal device may be indicated by joint coding. For example, the second indication information may include SLIV, or the second indication information may be SLIV, which may be used to jointly indicate the time domain position of the first resource of the sending carrier and the number of resources of the sending carrier, and the SLIV may uniquely correspond to a starting value (the time domain position of the first resource of the carrier sent by the first terminal device) and a length value (the number of resources of the carrier sent by the first terminal device).

[0280] In this embodiment, a resource may be a time unit, which may be, for example, a time range corresponding to one or more consecutive OFDM symbols, or one or more consecutive time slots, or one or more consecutive subframes.

[0281] In some embodiments, the second indication information may not include indication information for indicating the duration of the first terminal device sending the carrier, or in other words, the second indication information may not indicate the duration of the first terminal device sending the carrier. In some embodiments, the duration of the first terminal device sending the carrier may be configured by the network device, or may be predefined (such as a standard definition). As an implementation method, the duration of the first terminal device sending the carrier configured or predefined by the network device may be, for example, the duration corresponding to one sending resource. In this way, if the second indication information does not indicate the duration of the first terminal device sending the carrier, the second terminal device may deem that the duration of the first terminal device sending the carrier is the duration corresponding to one sending resource.

[0282] In some embodiments, the second indication information may not include indication information for indicating the number of resources for transmitting carriers by the first terminal device, or in other words, the second indication information may not indicate the number of resources for transmitting carriers by the first terminal device. In some embodiments, the number of resources for transmitting carriers by the first terminal device may be configured by a network device, or may be predefined (such as a standard definition). As an implementation method, the number of resources for transmitting carriers by the first terminal device configured or predefined by the network device may be, for example, 1. In this way, if the number of resources for transmitting carriers by the first terminal device is not indicated in the second indication information, the second terminal device may deem that the number of resources for transmitting carriers by the first terminal device is 1.

[0283] According to the method of this embodiment, the second terminal device can determine the time when the first terminal device transmits the carrier wave based on the second indication information. Furthermore, the second terminal device can determine the time when the reflected signal from the A-IoT device is received based on the time when the first terminal device transmits the carrier wave. In one possible embodiment, since the carrier wave transmitted by the first terminal device is used by the A-IoT device to transmit the reflected signal, or in other words, the reflected signal transmitted by the A-IoT device is transmitted by reflecting the carrier wave transmitted by the first terminal device, the time when the first terminal device transmits the carrier wave can be used as the time when the second terminal device receives the reflected signal.

[0284] In some embodiments, the second information can also be used by the second terminal device to receive one or more of the carrier, data, and signal sent by the first terminal device.

[0285] In some embodiments, the second information can be used by the second terminal device to receive the carrier transmitted by the first terminal device. For example, the second terminal device can determine one or more frequencies at which the first terminal device transmits the carrier based on the first indication information, thereby receiving the carrier transmitted by the first terminal device at the one or more frequencies. For another example, the second terminal device can determine the time at which the first terminal device transmits the carrier based on the second indication information, thereby receiving the carrier transmitted by the first terminal device at the time. In other words, the first indication information and the second indication information can be used by the second terminal device to receive the reflected signal from the A-IoT device, and can be used by the second terminal device to receive the carrier transmitted by the first terminal device.

[0286] In some embodiments, the second information may be used by the second terminal device to receive data or signals sent by the first terminal device. In this case, the second information may also include:

[0287] Fourth indication information, where the fourth indication information may be used to indicate a frequency at which the first terminal device sends data or signals; and / or,

[0288] The fifth indication information can be used to indicate the time when the first terminal device sends data or signals.

[0289] In some embodiments, the fourth indication information may include (or indicate): one or more frequencies at which the first terminal device sends data or signals; and / or one or more indexes corresponding to one or more frequencies at which the first terminal device sends data or signals.

[0290] In one example, the fourth indication information may include: one or more frequencies at which the first terminal device sends data or signals.

[0291] For example, the fourth indication information may include a frequency at which the first terminal device sends data or signals. In this case, the second terminal device may receive the data or signals sent by the first terminal device at the frequency.

[0292] For another example, the fourth indication information may include multiple frequencies at which the first terminal device sends data or signals. In this case, the second terminal device may receive the data or signals sent by the first terminal device on the multiple frequencies.

[0293] In one example, the fourth indication information may include: one or more indexes corresponding to one or more frequencies at which the first terminal device sends data or signals.

[0294] For example, the fourth indication information may include an index corresponding to a frequency at which the first terminal device sends data or signals. In this case, the second terminal device can determine a frequency at which the first terminal device sends data or signals based on the index, and then receive the data or signals sent by the first terminal device at this frequency.

[0295] For another example, the fourth indication information may include the indices corresponding to multiple frequencies on which the first terminal device transmits data or signals. The multiple frequencies may correspond to the same index, or the multiple frequencies may correspond one-to-one to multiple indices. In this case, the second terminal device may determine the multiple frequencies on which the first terminal device transmits data or signals based on the indices corresponding to the multiple frequencies, and may then receive the data or signals transmitted by the first terminal device on the multiple frequencies.

[0296] In some embodiments, the correspondence between one or more frequencies at which the first terminal device sends data or signals and the one or more indexes can be indicated by RRC signaling sent by the network device.

[0297] According to the method of this embodiment, the second terminal device can determine one or more frequencies at which the first terminal device sends data or signals based on the fourth indication information, and then can receive the data or signals sent by the first terminal device on the one or more frequencies.

[0298] In some embodiments, the fifth indication information may include indication information for indicating one or more of the following:

[0299] The moment when the first terminal device starts sending data or signals;

[0300] An index corresponding to the moment when the first terminal device starts sending data or signals (for example, recorded as the fourth index);

[0301] duration of the first terminal device sending data or signals;

[0302] The time domain position of the first resource for the first terminal device to send data or signals (that is, the time domain position of the first resource used for the first terminal device to send data or signals);

[0303] The number of resources used by the first terminal device to send data or signals (that is, the number of resources used by the first terminal device to send data or signals).

[0304] In some embodiments, the time at which the first terminal device begins transmitting data or signals is related to a third time interval and the time slot in which the second information is located. For example, the third time interval is the time interval between the time at which the first terminal device begins transmitting data or signals and the start or end point of the time slot in which the second information is located. The third time interval may be included in the fifth indication information. In this way, the second terminal device can determine the time at which the first terminal device begins transmitting data or signals based on the third time interval and the time slot in which the second information is located, and can then begin receiving the data or signals sent by the first terminal device at that time.

[0305] In some embodiments, the correspondence between the moment when the first terminal device starts sending data or signal and the fourth index can be indicated by RRC signaling sent by the network device.

[0306] In some embodiments, the fifth indication information may include indication information for indicating the following: the moment when the first terminal device starts sending data or signals, and the duration of the first terminal device sending data or signals. In this case, the moment when the first terminal device starts sending data or signals and the duration of the first terminal device sending data or signals may be indicated by joint coding. For example, the fifth indication information may include SLIV, or the fifth indication information may be SLIV, which may be used to jointly indicate the moment when the data or signal starts to be sent and the duration of the sending of the data or signal, and the SLIV may uniquely correspond to a starting point value (the moment when the first terminal device starts sending data or signals) and a length value (the duration of the first terminal device sending data or signals).

[0307] In some embodiments, the fifth indication information may include indication information for indicating the following: the time domain position of the first resource for sending data or signals by the first terminal device (such as the starting position of the first resource in the time domain), and the number of resources for sending data or signals by the first terminal device. In this case, the time domain position of the first resource for sending data or signals by the first terminal device and the number of resources for sending data or signals by the first terminal device may be indicated by joint coding. For example, the fifth indication information may include SLIV, or the fifth indication information may be SLIV, which may be used to jointly indicate the time domain position of the first resource for sending data or signals and the number of resources for sending data or signals, and the SLIV may uniquely correspond to a starting value (the time domain position of the first resource for sending data or signals by the first terminal device) and a length value (the number of resources for sending data or signals by the first terminal device).

[0308] In some embodiments, the fifth indication information may not include indication information for indicating the duration of the first terminal device sending data or signals, or in other words, the fifth indication information may not indicate the duration of the first terminal device sending data or signals. In some embodiments, the duration of the first terminal device sending data or signals may be configured by the network device, or may be predefined (such as a standard definition). As an implementation method, the duration of the first terminal device sending data or signals configured or predefined by the network device may be, for example, the duration corresponding to one sending resource. In this way, if the fifth indication information does not indicate the duration of the first terminal device sending data or signals, the second terminal device may deem that the duration of the first terminal device sending data or signals is the duration corresponding to one sending resource.

[0309] In some embodiments, the fifth indication information may not include indication information for indicating the number of resources for the first terminal device to send data or signals, or in other words, the fifth indication information may not indicate the number of resources for the first terminal device to send data or signals. In some embodiments, the number of resources for the first terminal device to send data or signals may be configured by the network device, or may be predefined (such as a standard definition). As an implementation method, the number of resources for the first terminal device to send data or signals configured or predefined by the network device may be, for example, 1. In this way, if the fifth indication information does not indicate the number of resources for the first terminal device to send data or signals, the second terminal device may deem that the number of resources for the first terminal device to send data or signals is 1.

[0310] According to the method of this embodiment, the second terminal device can determine the time when the first terminal device sends data or signals based on the fifth indication information, and then can receive the data or signals sent by the first terminal device at that time.

[0311] It should be noted that, since the sending direction can be omnidirectional when the first terminal device sends one or more of the carrier, data, and signal, the one or more of the carrier, data, and signal sent by the first terminal device can be received by the second terminal device and can also be received by the A-IoT device.

[0312] In some embodiments, the second information may include:

[0313] Eleventh indication information: the eleventh indication information may be used to indicate the frequency of receiving the reflected signal; and / or,

[0314] The twelfth indication information may be used to indicate the time of receiving the reflected signal.

[0315] In some embodiments, the eleventh indication information may include (or indicate): one or more frequencies at which the reflected signal is received; and / or one or more indexes corresponding to the one or more frequencies at which the reflected signal is received.

[0316] In one example, the eleventh indication information may include: one or more frequencies of received reflected signals.

[0317] For example, the eleventh indication information may include a frequency for receiving the reflected signal. In this case, the second terminal device may receive the reflected signal from the A-IoT device at the frequency.

[0318] For another example, the eleventh indication information may include multiple frequencies for receiving reflected signals. In this case, the second terminal device may receive reflected signals from the A-IoT device at the multiple frequencies.

[0319] In one example, the eleventh indication information may include: one or more indexes corresponding to one or more frequencies of received reflected signals.

[0320] For example, the eleventh indication information may include an index corresponding to a frequency for receiving the reflected signal. In this case, the second terminal device may determine a frequency for receiving the reflected signal based on the index, and then receive the reflected signal from the A-IoT device at this frequency.

[0321] For another example, the eleventh indication information may include: indexes corresponding to multiple frequencies at which reflected signals are received. The multiple frequencies may correspond to the same index, or the multiple frequencies may correspond one-to-one to multiple indexes. In this case, the second terminal device may determine the multiple frequencies at which reflected signals are received based on the indexes corresponding to the multiple frequencies, and may then receive reflected signals from the A-IoT device on the multiple frequencies.

[0322] In some embodiments, the correspondence between the one or more frequencies of the received reflected signal and the one or more indexes may be indicated by RRC signaling sent by the network device.

[0323] According to the method of this embodiment, the second terminal device can determine one or more frequencies for receiving the reflected signal based on the eleventh indication information, and then can receive the reflected signal from the A-IoT device at the one or more frequencies.

[0324] In some embodiments, the twelfth indication information may include indication information for indicating one or more of the following:

[0325] The moment when the reflected signal starts to be received;

[0326] The index corresponding to the time when the reflected signal starts to be received (for example, recorded as the tenth index);

[0327] Duration of receiving reflected signal;

[0328] a time domain position of a first resource for receiving a reflected signal (that is, a time domain position of a first resource for receiving a reflected signal);

[0329] The number of resources for receiving reflected signals (that is, the number of resources used to receive reflected signals).

[0330] In some embodiments, the time at which the reflected signal begins to be received is related to the fifth time interval and the time slot in which the second information is located. For example, the fifth time interval is the time interval between the time at which the reflected signal begins to be received and the start or end point of the time slot in which the second information is located. The fifth time interval may be included in the twelfth indication information. In this way, the second terminal device may determine the time at which the reflected signal begins to be received based on the fifth time interval and the time slot in which the second information is located. Furthermore, the second terminal device may begin receiving the reflected signal from the A-IoT device at this time.

[0331] In some embodiments, the correspondence between the time when the reflected signal starts to be received and the tenth index may be indicated by RRC signaling sent by the network device.

[0332] In some embodiments, the twelfth indication information may include indication information for indicating the following: the time when the reflected signal starts to be received and the duration of the reflected signal reception. In this case, the time when the reflected signal starts to be received and the duration of the reflected signal reception may be indicated by a joint encoding. For example, the twelfth indication information may include SLIV, or the twelfth indication information may be SLIV, which may be used to jointly indicate the time when the reflected signal starts to be received and the duration of the reflected signal reception, and the SLIV may uniquely correspond to a starting point value (the time when the reflected signal reception starts) and a length value (the duration of the reflected signal reception).

[0333] In some embodiments, the twelfth indication information may include indication information for indicating the following: the time domain position of the first resource receiving the reflected signal (such as the starting position of the first resource in the time domain), and the number of resources receiving the reflected signal. In this case, the time domain position of the first resource receiving the reflected signal and the number of resources receiving the reflected signal may be indicated by joint coding. For example, the twelfth indication information may include SLIV, or the twelfth indication information may be SLIV, which may be used to jointly indicate the time domain position of the first resource receiving the reflected signal and the number of resources receiving the reflected signal, and the SLIV may uniquely correspond to a starting point value (the time domain position of the first resource receiving the reflected signal) and a length value (the number of resources receiving the reflected signal).

[0334] In some embodiments, the twelfth indication information may not include indication information for indicating the duration of receiving the reflected signal, or in other words, the twelfth indication information may not indicate the duration of receiving the reflected signal. In some embodiments, the duration of receiving the reflected signal may be configured by the network device, or may be predefined (such as a standard definition). As an implementation method, the duration of receiving the reflected signal configured or predefined by the network device may be, for example, the duration corresponding to one transmission resource. In this way, if the duration of receiving the reflected signal is not indicated in the twelfth indication information, the second terminal device may deem the duration of receiving the reflected signal to be the duration corresponding to one transmission resource.

[0335] In some embodiments, the twelfth indication information may not include indication information for indicating the number of resources for receiving reflected signals, or in other words, the twelfth indication information may not indicate the number of resources for receiving reflected signals. In some embodiments, the number of resources for receiving reflected signals may be configured by the network device, or may be predefined (such as defined by a standard). As an implementation, the number of resources for receiving reflected signals configured or predefined by the network device may be, for example, 1. In this case, if the number of resources for receiving reflected signals is not indicated in the twelfth indication information, the second terminal device may deem the number of resources for receiving reflected signals to be 1.

[0336] According to the method of this embodiment, the second terminal device can determine the time to receive the reflected signal based on the twelfth indication information, and then can receive the reflected signal from the A-IoT device at this time.

[0337] In some embodiments, the second information can also be used by the second terminal device to receive the carrier sent by the first terminal device; wherein the frequency of receiving the carrier is the same as the frequency of receiving the reflected signal; and the time of receiving the carrier is the same as the time of receiving the reflected signal.

[0338] For example, the second terminal device may determine the frequency of receiving the reflected signal based on the eleventh indication information, and this frequency may also be used by the second terminal device to receive the carrier transmitted by the first terminal device. For another example, the second terminal device may determine the time of receiving the reflected signal based on the twelfth indication information, and this time may also be used by the second terminal device to receive the carrier transmitted by the first terminal device. In other words, the eleventh indication information and the twelfth indication information may be used by the second terminal device to receive the reflected signal from the A-IoT device, and may also be used by the second terminal device to receive the carrier transmitted by the first terminal device.

[0339] In some embodiments, the second information may also be used by the second terminal device to receive data or signals sent by the first terminal device. In this case, the second information may also include:

[0340] Thirteenth indication information, the thirteenth indication information may be used to indicate a frequency of receiving data or signals; and / or,

[0341] Fourteenth indication information: The fourteenth indication information may be used to indicate the time of receiving data or signals.

[0342] In some embodiments, the thirteenth indication information may include (or indicate): one or more frequencies at which data or signals are received; and / or one or more indexes corresponding to the one or more frequencies at which data or signals are received.

[0343] In one example, the thirteenth indication information may include: one or more frequencies for receiving data or signals.

[0344] For example, the thirteenth indication information may include a frequency for receiving data or signals. In this case, the second terminal device may receive the data or signals sent by the first terminal device at the frequency.

[0345] For another example, the thirteenth indication information may include multiple frequencies for receiving data or signals. In this case, the second terminal device may receive the data or signals sent by the first terminal device on the multiple frequencies.

[0346] In one example, the thirteenth indication information may include: one or more indexes corresponding to one or more frequencies of received data or signals.

[0347] For example, the thirteenth indication information may include an index corresponding to a frequency for receiving data or signals. In this case, the second terminal device can determine a frequency for receiving data or signals based on the index, and then receive the data or signals sent by the first terminal device at this frequency.

[0348] For another example, the thirteenth indication information may include: indices corresponding to multiple frequencies for receiving data or signals. The multiple frequencies may correspond to the same index, or the multiple frequencies may correspond one-to-one to multiple indices. In this case, the second terminal device may determine the multiple frequencies for receiving data or signals based on the indices corresponding to the multiple frequencies, and may then receive the data or signals sent by the first terminal device on the multiple frequencies.

[0349] In some embodiments, the correspondence between one or more frequencies of receiving data or signals and the one or more indexes may be indicated by RRC signaling sent by the network device.

[0350] According to the method of this embodiment, the second terminal device can determine one or more frequencies for receiving data or signals based on the thirteenth indication information, and then can receive the data or signals sent by the first terminal device on the one or more frequencies.

[0351] In some embodiments, the fourteenth indication information includes indication information for indicating one or more of the following:

[0352] The moment when data or signal reception begins;

[0353] The index corresponding to the time when data or signal reception starts (e.g., recorded as the eleventh index);

[0354] Duration of receiving data or signals;

[0355] A time domain position of a first resource for receiving data or a signal (ie, a time domain position of a first resource for receiving data or a signal);

[0356] The number of resources for receiving data or signals (that is, the number of resources used to receive data or signals).

[0357] In some embodiments, the time at which data or signal reception begins is related to the sixth time interval and the time slot in which the second information is located. For example, the sixth time interval is the time interval between the time at which data or signal reception begins and the start or end of the time slot in which the second information is located. The sixth time interval may be included in the fourteenth indication information. In this way, the second terminal device may determine the time at which data or signal reception begins based on the sixth time interval and the time slot in which the second information is located. Furthermore, the second terminal device may begin receiving data or signals sent by the first terminal device at this time.

[0358] In some embodiments, the correspondence between the time when data or signal reception starts and the eleventh index may be indicated by RRC signaling sent by the network device.

[0359] In some embodiments, the fourteenth indication information may include indication information for indicating the following: the moment when data or signal reception starts, and the duration of receiving the data or signal. In this case, the moment when data or signal reception starts and the duration of receiving the data or signal may be indicated by joint coding. For example, the fourteenth indication information may include SLIV, or the fourteenth indication information may be SLIV, which may be used to jointly indicate the moment when data or signal reception starts and the duration of receiving the data or signal, and the SLIV may uniquely correspond to a starting point value (the moment when data or signal reception starts) and a length value (the duration of receiving the data or signal).

[0360] In some embodiments, the fourteenth indication information may include indication information for indicating the following: the time domain position of the first resource for receiving data or signals (such as the starting position of the first resource in the time domain), and the number of resources for receiving data or signals. In this case, the time domain position of the first resource for receiving data or signals and the number of resources for receiving data or signals may be indicated by joint coding. For example, the fourteenth indication information may include SLIV, or the fourteenth indication information may be SLIV, which may be used to jointly indicate the time domain position of the first resource for receiving data or signals and the number of resources for receiving data or signals, and the SLIV may uniquely correspond to a starting point value (the time domain position of the first resource for receiving data or signals) and a length value (the number of resources for receiving data or signals).

[0361] In some embodiments, the fourteenth indication information may not include indication information for indicating the duration of receiving data or signals, or in other words, the fourteenth indication information may not indicate the duration of receiving data or signals. In some embodiments, the duration of receiving data or signals may be configured by the network device, or may be predefined (such as a standard definition). As an implementation method, the duration of receiving data or signals configured or predefined by the network device may be, for example, the duration corresponding to one sending resource. In this way, if the duration of receiving data or signals is not indicated in the fourteenth indication information, the second terminal device may deem the duration of receiving data or signals to be the duration corresponding to one sending resource.

[0362] In some embodiments, the fourteenth indication information may not include indication information for indicating the number of resources for receiving data or signals, or in other words, the fourteenth indication information may not indicate the number of resources for receiving data or signals. In some embodiments, the number of resources for receiving data or signals may be configured by a network device, or may be predefined (such as a standard definition). As an implementation method, the number of resources for receiving data or signals configured or predefined by a network device may be, for example, 1. In this way, if the number of resources for receiving data or signals is not indicated in the fourteenth indication information, the second terminal device may deem that the number of resources for receiving data or signals is 1.

[0363] According to the method of this embodiment, the second terminal device can determine the time to receive data or signals based on the fourteenth indication information, and then can receive the data or signals sent by the first terminal device at this time.

[0364] In some embodiments, the second information may further include: fifteenth indication information, which may be used to indicate the power of one or more of the carrier, data, and signal sent by the first terminal device.

[0365] Illustratively, the fifteenth indication information may include one or more of the following, or in other words, the fifteenth indication information may indicate one or more of the following:

[0366] The power of one or more of the carrier, data, and signal transmitted by the first terminal device;

[0367] A power range for transmitting one or more of a carrier, data, and a signal by the first terminal device;

[0368] An index corresponding to the power of one or more of the carrier, data, and signal transmitted by the first terminal device (the corresponding relationship may be indicated by RRC signaling sent by the network device);

[0369] An index corresponding to a power range for transmitting one or more of a carrier, data, and a signal by the first terminal device (the corresponding relationship may be indicated by RRC signaling sent by the network device);

[0370] Relative to the adjustment value of the reference transmission power, the power of one or more of the carrier, data, and signal transmitted by the first terminal device is related to the adjustment value.

[0371] According to the method of this embodiment, the second terminal device can obtain the power of one or more of the carrier, data, and signal sent by the first terminal device based on the fifteenth indication information. In some embodiments, the power can be used by the second terminal device to eliminate or reduce the interference of one or more of the carrier, data, and signal on the reflected signal sent by the A-IoT device. For example, the reflected signal sent by the A-IoT device may be superimposed with one or more of the carrier, data, and signal sent by the first terminal device. Then, when the second terminal device knows the power, it can eliminate the one or more of the carrier, data, and signal superimposed in the reflected signal based on the power.

[0372] In some embodiments, the second information may be DCI (for example, denoted as third DCI).

[0373] In some embodiments, the number of bits of the third DCI may be the same as the number of bits of the second DCI currently configured by the second terminal device, and the third DCI and the second DCI may be scrambled by different RNTIs. The second DCI may be, for example, an uplink DCI, a downlink DCI, or a sidelink DCI.

[0374] In some embodiments, the number of bits of the third DCI may be configured by the network device. If the number of bits contained in all bit fields in the third DCI is less than the number of bits configured by the network device, zeros may be added to the end of the third DCI.

[0375] In some embodiments, the second information can be the same as the first information in the aforementioned embodiment, that is, the third DCI can be the same as the first DCI in the aforementioned embodiment. At this time, the first DCI and the third DCI can be encrypted by the RNTI shared by the first terminal device and the second terminal device.

[0376] In some embodiments, the second information is different from the first information in the aforementioned embodiment, that is, the third DCI is different from the first DCI in the aforementioned embodiment. In this case, the third DCI and the first DCI may have the same format, and the network device may pad the end of the third DCI or the first DCI with fewer bits to ensure that the third DCI and the first DCI have the same number of bits. In some embodiments, the third DCI and the first DCI may be scrambled using different RNTIs.

[0377] In some embodiments, the second information is a configuration authorization.

[0378] In some embodiments, when the first information is configuration authorization, the second information may include indication information for indicating one or more of the following:

[0379] The repetition period of the carrier resource sent by the first terminal device in the time domain;

[0380] A repetition period in the time domain of resources used by the first terminal device to send data or signals;

[0381] a repetition period of the resources for receiving the reflected signals in the time domain (that is, a repetition period of the resources for receiving the reflected signals in the time domain);

[0382] The repetition period in the time domain of resources for receiving data or signals sent by the first terminal device (that is, the repetition period in the time domain of resources for receiving data or signals sent by the first terminal device).

[0383] Among them, the repetition period in the time domain of the resources for sending the carrier wave by the first terminal device can be used by the second terminal device to receive the reflected signal from the A-IoT device. In some embodiments, it can also be used by the second terminal device to receive the carrier wave sent by the first terminal device. The repetition period in the time domain of the resources for sending data or signals by the first terminal device can be used by the second terminal device to receive the data or signal sent by the first terminal device. The repetition period in the time domain of the resources for receiving the reflected signal (the same as the repetition period in the time domain of the resources for receiving the carrier wave) can be used by the second terminal device to receive the reflected signal from the A-IoT device. In some embodiments, it can also be used by the second terminal device to receive the carrier wave sent by the first terminal device. The repetition period in the time domain of the resources for receiving the data or signal sent by the first terminal device can be used by the second terminal device to receive the data or signal sent by the first terminal device.

[0384] According to the method of this embodiment, the second terminal device can receive the reflected signal from the A-IoT device based on the second information from the network device. In other words, the network device can schedule / control communication between the second terminal device and the A-IoT device by sending the second information to the second terminal device.

[0385] The above describes the communication method provided in the embodiments of the present application. To facilitate understanding of the embodiments of the present application, the following describes possible implementation schemes of the communication method applicable to the embodiments of the present application with reference to examples.

[0386] Option 1

[0387] In solution one, the number of terminal devices (intermediate nodes) is one, and the terminal device can send one or more of carriers, data, and signals to the A-IoT device based on the DCI (an example of the first information) sent by the network device (such as a base station). In other words, the DCI can be used by the terminal device to send one or more of carriers, data, and signals to the A-IoT device.

[0388] Exemplarily, according to the network configuration or predefinition (such as standard definition), the terminal device may send the DCI sent by the network device in one of the following ways:

[0389] Method 1: Send a carrier wave to the A-IoT device.

[0390] Method 2: Send data / signals to A-IoT devices.

[0391] Method 3: Sending a carrier wave and data / signal to an A-IoT device. For example, data / signal is sent first, followed by the carrier wave, in chronological order (method 3-1). Another example is sending the carrier wave and data / signal on different frequencies (method 3-2).

[0392] Method 4: The terminal device decides whether to send data / signal or carrier.

[0393] Among them, sending a carrier wave refers to sending a sinusoidal electromagnetic wave of a specific frequency that does not carry data and signals.

[0394] The above methods are introduced below.

[0395] Method 1

[0396] In method 1, the terminal device can send a carrier to the A-IoT device. In this case, the DCI (hereinafter referred to as DCI-1-1) sent by the network device to the terminal device can indicate at least one or more of the following information 11) to 14):

[0397] 11) Carrier frequency (the frequency of the transmitted carrier).

[0398] In one example, DCI-1-1 may indicate (or include) the frequency (such as absolute frequency) of the carrier.

[0399] In some embodiments, DCI-1-1 may indicate (or include) one or more frequencies of the carrier. If multiple frequencies are indicated (or included), the terminal device may transmit the carrier on the multiple frequencies.

[0400] As another example, DCI-1-1 may indicate (or include) an index corresponding to one or more frequencies (e.g., absolute frequencies) of a carrier. That is, one or more frequencies of a carrier may be indicated by indicating the index corresponding to one or more frequencies of the carrier. The frequency of the carrier corresponding to a certain index may be indicated by RRC signaling, for example.

[0401] In some embodiments, an index may correspond to one or more frequencies. If an index corresponds to multiple frequencies, the terminal device may transmit carriers on the multiple frequencies corresponding to the index. The fact that an index corresponds to multiple frequencies can also be understood as the index corresponding to a frequency group (carrier frequency group), which may correspond to multiple carriers configured by RRC signaling.

[0402] In some embodiments, the network device may determine the number of frequencies indicated (or included) in DCI-1-1 based on the capability report of the terminal device.

[0403] 12) The time when the carrier transmission starts, or the time position (time domain position) of the transmission resources used to transmit the carrier.

[0404] In one example, DCI-1-1 may indicate (or include) the time when the carrier starts to be transmitted.

[0405] The time when carrier transmission starts can be represented, for example, as the interval (time interval) between the time position of starting carrier transmission and the start or end point of the time slot where DCI-1-1 is located. The time position of starting carrier transmission can be the start point of a time slot, the start point of an OFDM symbol, or the start point of a subframe. Accordingly, the granularity of the interval can be a time slot, an OFDM symbol, or a subframe.

[0406] As another example, DCI-1-1 may indicate (or include) the index corresponding to the time when carrier transmission starts. That is, the time when carrier transmission starts can be indicated by indicating the index corresponding to the time when carrier transmission starts. The correspondence between an index and the time when carrier transmission starts can be indicated, for example, by RRC signaling.

[0407] As another example, DCI-1-1 may indicate (or include) the time position of the transmission resource for transmitting the carrier.

[0408] For example, DCI-1-1 may indicate (or include) the time position of the first transmission resource used to transmit the carrier. The transmission resource used to transmit the carrier may be, for example, a time unit used to transmit the carrier, and the time unit may be, for example, a time range corresponding to one or more consecutive OFDM symbols, or one or more consecutive time slots, or one or more consecutive subframes.

[0409] 13) The duration of the carrier transmission, or the number of transmission resources used to transmit the carrier.

[0410] The duration of the carrier transmission may be expressed as, for example, the number of consecutive uplink time slots, or the number of consecutive uplink OFDM symbols, or the number of consecutive uplink subframes.

[0411] In some embodiments, the time at which carrier transmission starts and the duration of carrier transmission can be jointly indicated. For example, the time at which carrier transmission starts and the duration of carrier transmission can be indicated by SLIV. Each SLIV uniquely corresponds to a starting point value (the time at which carrier transmission starts) and a length value (the duration of carrier transmission).

[0412] In some embodiments, the time position of a transmission resource used to transmit a carrier (e.g., the time position of the first transmission resource) and the number of transmission resources used to transmit the carrier can be jointly indicated. For example, the time position of the first transmission resource used to transmit a carrier and the number of transmission resources used to transmit the carrier can be indicated by SLIV, where each SLIV uniquely corresponds to a starting point value (the time position of the first transmission resource) and a length value (the number of transmission resources).

[0413] In some embodiments, this information (the duration of the transmission carrier or the number of transmission resources used to transmit the carrier) may not exist. In the case that this information does not exist, the duration of the transmission carrier or the number of transmission resources used to transmit the carrier may be configured or predefined by the network (such as a standard definition). In some embodiments, the duration of the transmission carrier may be, for example, the duration corresponding to 1 transmission resource. In some embodiments, the number of transmission resources used to transmit the carrier may be, for example, 1. That is, if this information does not exist, the terminal device may deem the duration of the transmission carrier to be the duration corresponding to 1 transmission resource; or, the terminal device may deem the number of transmission resources used to transmit the carrier to be 1.

[0414] 14) The power of the transmitted carrier.

[0415] In one example, DCI-1-1 may indicate (or include) a power value or a power range of a transmitting carrier.

[0416] As another example, DCI-1-1 may indicate (or include) an index corresponding to the power value or power range of the transmitting carrier. That is, the power value or power range of the transmitting carrier may be indicated by indicating the index corresponding to the power value or power range of the transmitting carrier. Each index may correspond to a power value or power range configured by the RRC layer, or in other words, the power value or power range corresponding to each index may be configured by RRC signaling.

[0417] As another example, DCI-1-1 may indicate (or include) a transmit power control command, that is, the power of the transmit carrier may be indicated by the transmit power control command.

[0418] The transmit power control command may indicate an adjustment value relative to a reference transmit power, based on which the terminal device may determine the power at which the carrier is transmitted. The reference transmit power may be, for example, a transmit power last used by the terminal device (e.g., the transmit power used when the carrier, data, or signal was last transmitted).

[0419] In some embodiments, this information (transmitting carrier power) may not exist. In the absence of this information, the transmitting carrier power used by the terminal device may be the same as the current uplink transmit power, or may be the currently allowed maximum transmit power.

[0420] In some embodiments, DCI-1-1 may indicate (or include) all of the above information, that is, may indicate (or include) information 11) to 14).

[0421] Method 2

[0422] In method 2, the terminal device can send data / signals to the A-IoT device. In this case, the DCI (hereinafter referred to as DCI-1-2) sent by the network device to the terminal device can indicate at least one or more of the following information 21) to 25):

[0423] 21) The frequency at which data / signals are transmitted (i.e., the carrier frequency of the transmitted data / signals).

[0424] In one example, DCI-1-2 may indicate (or include) the frequency (eg, absolute frequency) at which data / signals are transmitted.

[0425] In some embodiments, DCI-1-2 may indicate (or include) one or more frequencies for transmitting data / signals. If multiple frequencies are indicated (or included), the terminal device may transmit carriers on the multiple frequencies.

[0426] As another example, DCI-1-2 may indicate (or include) the index corresponding to one or more frequencies (e.g., absolute frequencies) at which data / signals are transmitted. That is, by indicating the index corresponding to one or more frequencies at which data / signals are transmitted, one or more frequencies at which data / signals are transmitted may be indicated. The frequency corresponding to a particular index may be indicated by RRC signaling, for example.

[0427] In some embodiments, an index may correspond to one or more frequencies. If an index corresponds to multiple frequencies, the terminal device may send data / signals on the multiple frequencies corresponding to the index. The fact that an index corresponds to multiple frequencies can also be understood as the index corresponding to a frequency group (carrier frequency group), which may correspond to multiple carriers configured by RRC signaling.

[0428] In some embodiments, the network device may determine the number of frequencies indicated (or included) in DCI-1-2 based on the capability report of the terminal device.

[0429] 22) The time when data / signal transmission starts, or the time position of the transmission resources used to transmit data / signal.

[0430] For example, DCI-1-2 may indicate (or include) the time when data / signal transmission starts.

[0431] The time when data / signal transmission starts can be represented, for example, as the interval (time interval) between the time position of the start of data / signal transmission and the start or end point of the time slot where DCI-1-2 is located. The time position of the start of data / signal transmission can be the start point of a time slot, the start point of an OFDM symbol, or the start point of a subframe. Accordingly, the granularity of the interval can be a time slot, an OFDM symbol, or a subframe.

[0432] As another example, DCI-1-2 may indicate (or include) an index corresponding to the time when data / signal transmission starts. That is, the time when data / signal transmission starts may be indicated by indicating the index corresponding to the time when data / signal transmission starts. The correspondence between an index and the time when data / signal transmission starts may be indicated, for example, by RRC signaling.

[0433] As another example, DCI-1-2 may indicate (or include) the time location of the transmission resource used to transmit data / signal.

[0434] For example, DCI-1-2 may indicate (or include) the time position of the first transmission resource used to transmit data / signal. The transmission resource used to transmit data / signal may be, for example, a time unit used to transmit data / signal, and the time unit may be, for example, a time range corresponding to one or more consecutive OFDM symbols, or one or more consecutive time slots, or one or more consecutive subframes.

[0435] 23) The duration of sending data / signals, or the number of sending resources used to send data / signals.

[0436] The duration of sending data / signals may be expressed as, for example, the number of consecutive uplink time slots, or the number of consecutive uplink OFDM symbols, or the number of consecutive uplink subframes.

[0437] In some embodiments, the time when data / signal transmission starts and the duration of data / signal transmission can be jointly indicated. For example, the time when data / signal transmission starts and the duration of data / signal transmission can be indicated by SLIV, and each SLIV uniquely corresponds to a starting point value (the time when data / signal transmission starts) and a length value (the duration of data / signal transmission).

[0438] In some embodiments, the time position of a transmission resource used to transmit data / signals (e.g., the time position of the first transmission resource) and the number of transmission resources used to transmit data / signals may be jointly indicated. For example, the time position of the first transmission resource used to transmit data / signals and the number of transmission resources used to transmit data / signals may be indicated by SLIVs, where each SLIV uniquely corresponds to a starting point value (the time position of the first transmission resource) and a length value (the number of transmission resources).

[0439] In some embodiments, this information (the duration of sending data / signal or the number of sending resources used to send data / signal) may not exist. In the case that this information does not exist, the duration of sending data / signal or the number of sending resources used to send data / signal may be configured or predefined by the network (such as a standard definition). In some embodiments, the duration of sending data / signal may be, for example, the duration corresponding to 1 sending resource. In some embodiments, the number of sending resources used to send data / signal may be, for example, 1. That is, if this information does not exist, the terminal device may deem the duration of sending data / signal to be the duration corresponding to 1 sending resource; or, the terminal device may deem the number of sending resources used to send data / signal to be 1.

[0440] 24) The power of the transmitted data / signal.

[0441] In one example, DCI-1-2 may indicate (or include) a power value or a power range for transmitting data / signal.

[0442] As another example, DCI-1-2 may indicate (or include) an index corresponding to a power value or power range for transmitting data / signals. That is, the power value or power range for transmitting data / signals may be indicated by indicating an index corresponding to the power value or power range for transmitting data / signals.

[0443] Each index may correspond to a certain power value or power range configured by the RRC layer, or in other words, the power value or power range corresponding to each index may be configured by RRC signaling.

[0444] As another example, DCI-1-2 may indicate (or include) a transmit power control command, that is, the power of transmitting data / signals may be indicated by transmitting the power control command.

[0445] The transmit power control command may indicate an adjustment value relative to a reference transmit power, based on which the terminal device may determine the power at which to transmit data / signals. The reference transmit power may be, for example, a transmit power last used by the terminal device (e.g., the transmit power used when the carrier, data, or signal was last transmitted).

[0446] In some embodiments, this information (power of transmitting data / signal) may not exist. In the absence of this information, the power of transmitting data / signal adopted by the terminal device may be the same as the current uplink transmit power, or may be the currently allowed maximum transmit power.

[0447] 25) ID of one or more A-IoT devices

[0448] The terminal device can send data / signals to the corresponding A-IoT device based on the ID of one or more A-IoT devices.

[0449] In some embodiments, DCI-1-2 may indicate (or include) all of the above information, that is, may indicate (or include) information 21) to 25).

[0450] In some embodiments, DCI-1-2 may indicate (or include) all information except the IDs of one or more A-IoT devices, that is, it may indicate (or include) information 21) to 24). In this case, the terminal device (e.g., a higher layer of the terminal device) may decide to which A-IoT device or devices to send data / signals.

[0451] Method 3-1

[0452] In method 3-1, the terminal device may send data / signals to the A-IoT device first, and then send carriers to the A-IoT device in chronological order.

[0455] In some embodiments, this information may not exist. In the absence of this information, the terminal device may assume that the frequency of the transmitting carrier is the same as the frequency of the transmitting data / signal indicated in DCI-1-3.

[0458] In some embodiments, this information may not exist. In the absence of this information, the terminal device may send the carrier after a specific interval (time interval) after sending the data / signal. The specific interval may be configured or predefined by the network (such as defined by the standard).

[0459] 313) The duration of the carrier transmission, or the number of transmission resources used to transmit the carrier.

[0460] The content or indication method of this information can refer to the description of information 13) in method 1, which will not be repeated here.

If this information does not exist, the duration of the carrier transmission, or the number of transmission resources used to transmit the carrier, may be configured or predefined by the network (e.g., as defined by a standard). In some embodiments, the duration of the carrier transmission may be, for example, the duration corresponding to one transmission resource. In some embodiments, the number of transmission resources used to transmit the carrier may be, for example, one.

[0462] 314) The power of the transmitted carrier.

[0463] In one example, DCI-1-3 may indicate (or include) a power value or a power range of a transmitting carrier.

[0464] As another example, DCI-1-3 may indicate (or include) an index corresponding to the power value or power range of the transmitting carrier. That is, the power value or power range of the transmitting carrier may be indicated by indicating the index corresponding to the power value or power range of the transmitting carrier. Each index may correspond to a power value or power range configured by the RRC layer, or in other words, the power value or power range corresponding to each index may be configured by RRC signaling.

[0465] As another example, DCI-1-3 may indicate (or include) a transmit power control command, that is, the power of the transmit carrier may be indicated by the transmit power control command.

[0466] The transmit power control command may indicate an adjustment value relative to a reference transmit power, based on which the terminal device may determine the power of the transmitted carrier. The reference transmit power may be, for example, the power of the transmitted data / signal indicated in DCI-1-3.

[0467] In some embodiments, this information (transmitting carrier power) may not exist. In the absence of this information, the transmitting carrier power used by the terminal device may be the same as the current uplink transmit power, or the currently allowed maximum transmit power, or the same as the transmit data / signal power indicated in DCI-1-3.

[0468] Method 3-2

[0469] In mode 3-2, the terminal device can send carriers and data / signals to the A-IoT device on different frequencies. In this case, the DCI (hereinafter referred to as DCI-1-4) sent by the network device to the terminal device may at least indicate (or include) all or part of the information in DCI-1-1 and / or all or part of the information in DCI-1-2. For example, DCI-1-4 may at least indicate (or include) one or more of the following information 321) to 328):

[0470] 321) Carrier frequency (the frequency of the transmitting carrier).

[0471] The content or indication method of this information can refer to the description of information 11) in method 1, which will not be repeated here.

[0472] 322) The time when the carrier starts to be transmitted, or the time position of the transmission resources used to transmit the carrier.

[0479] The content or indication method of this information can refer to the description of information 14) in method 1.

[0480] In some embodiments, for different carriers, the power of transmitting the carriers may be the same or different. If different, the transmission power may be indicated separately for different carriers.

[0481] 325) The frequency at which data / signals are transmitted (i.e., the carrier frequency at which data / signals are transmitted).

[0482] The content or indication method of this information can refer to the description of information 21) in method 2, which will not be repeated here.

[0483] In mode 3-2, the frequency of transmitting data / signals and the frequency of transmitting carrier waves are different.

[0484] 326) The time when data / signal transmission starts, or the time position of the transmission resources used to transmit data / signal.

[0485] The content or indication method of this information can refer to the description of information 22) in method 2.

[0486] In some embodiments, for different data / signals (data / signals carried on different carriers), the time of starting to send the data / signal or the time position of the sending resources used to send the data / signal may be the same or different. If different, they may be indicated separately for different data / signals.

[0487] 327) The duration of sending data / signals, or the number of sending resources used to send data / signals.

[0488] The content or indication method of this information can refer to the description of information 23 in method 2).

[0489] In some embodiments, for different data / signals (data / signals carried on different carriers), the duration of sending data / signals or the number of sending resources used to send data / signals may be the same or different. If different, they may be indicated separately for different data / signals.

[0490] 328) The power of sending data / signal.

[0491] The content or indication method of this information can refer to the description of information 24) in method 2.

[0492] In some embodiments, for different data / signals (data / signals carried on different carriers), the power of transmitting the data / signals may be the same or different. If different, the transmission power may be indicated separately for different data / signals.

[0493] In some embodiments, this information (power of transmitting data / signal) may not exist. In the absence of this information, the power of transmitting data / signal adopted by the terminal device may be the same as the power of the transmitting carrier indicated in DCI-1-4.

[0494] Method 4

[0495] In mode 4, after receiving DCI from the network device, the terminal device can decide whether to send data / signals or carriers to the A-IoT device. In this case, the DCI (hereinafter referred to as DCI-1-5) sent by the network device to the terminal device can indicate at least one or more of the following information 41) to 44):

[0496] 41) Frequency of the carrier.

[0497] When the terminal device decides to send a carrier wave to the A-IoT device, the frequency of the carrier wave may be the frequency of the transmitting carrier wave. When the terminal device decides to send data / signals to the A-IoT device, the frequency of the carrier wave may be the frequency of the transmitting data / signals (carrier frequency).

[0498] In one example, DCI-1-5 may indicate (or include) the frequency (eg, absolute frequency) of the carrier.

[0499] In some embodiments, DCI-1-5 may indicate (or include) one or more frequencies of a carrier. If multiple frequencies are indicated (or included), the terminal device may transmit the carrier or send data / signals on the multiple frequencies.

[0500] As another example, DCI-1-5 may indicate (or include) an index corresponding to one or more frequencies (e.g., absolute frequencies) of a carrier. That is, one or more frequencies of a carrier may be indicated by indicating the index corresponding to one or more frequencies of the carrier. The frequency of the carrier corresponding to a certain index may be indicated by RRC signaling, for example.

[0501] In some embodiments, an index may correspond to one or more frequencies. If an index corresponds to multiple frequencies, the terminal device may transmit a carrier or send data / signals on the multiple frequencies corresponding to the index. Wherein, an index corresponds to multiple frequencies, which can also be understood as the index corresponding to a frequency group (carrier frequency group), which can correspond to multiple carriers configured by RRC signaling.

[0502] In some embodiments, the network device may determine the number of frequencies indicated (or included) in DCI-1-5 based on the capability report of the terminal device.

[0503] 42) The time when the sending starts, or the time location of the sending resource.

[0504] When the terminal device decides to send a carrier wave to the A-IoT device, the time of starting transmission may be the time of starting to send the carrier wave, and the time position of the transmission resource may be the time position of the transmission resource used to send the carrier wave. When the terminal device decides to send data / signals to the A-IoT device, the time of starting transmission may be the time of starting to send the data / signals, and the time position of the transmission resource may be the time position of the transmission resource used to send the data / signals.

[0505] As an example, DCI-1-5 may indicate (or include) the time to start sending.

[0506] The time of starting transmission can be represented, for example, as the interval (time interval) between the time position of starting transmission and the start or end point of the time slot where DCI-1-5 is located. The time position of starting transmission can be the start point of a time slot, the start point of an OFDM symbol, or the start point of a subframe. Accordingly, the granularity of the interval can be a time slot, an OFDM symbol, or a subframe.

[0507] As another example, DCI-1-5 may indicate (or include) an index corresponding to the time at which transmission starts. That is, the time at which transmission starts may be indicated by indicating the index corresponding to the time at which transmission starts. The correspondence between an index and the time at which transmission starts may be indicated, for example, by RRC signaling.

[0508] As another example, DCI-1-5 may indicate (or include) the time location of the sending resource.

[0509] For example, DCI-1-5 may indicate (or include) the time position of the first transmission resource. A transmission resource may be, for example, a time unit, which may be, for example, a time range corresponding to one or more consecutive OFDM symbols, or one or more consecutive time slots, or one or more consecutive subframes.

[0510] 43) The duration of the transmission, or the number of resources sent.

[0511] When the terminal device decides to send a carrier to the A-IoT device, the transmission duration may be the duration of sending the carrier, and the number of transmission resources may be the number of transmission resources used to send the carrier. When the terminal device decides to send data / signals to the A-IoT device, the transmission duration may be the duration of sending the data / signals, and the number of transmission resources may be the number of transmission resources used to send the data / signals.

[0512] The transmission duration may be expressed as, for example, the number of consecutive uplink time slots, or the number of consecutive uplink OFDM symbols, or the number of consecutive uplink subframes.

[0513] In some embodiments, the time to start sending and the duration of sending can be jointly indicated. For example, the time to start sending and the duration of sending can be indicated by SLIV, and each SLIV uniquely corresponds to a starting point value (the time to start sending) and a length value (the duration of sending).

[0514] In some embodiments, the time position of a transmitted resource (e.g., the time position of the first transmitted resource) and the number of transmitted resources may be jointly indicated. For example, the time position of the first transmitted resource and the number of transmitted resources may be indicated by a SLIV, where each SLIV uniquely corresponds to a starting point value (the time position of the first transmitted resource) and a length value (the number of transmitted resources).

[0515] In some embodiments, this information (sending duration or number of sending resources) may not exist. In the event that this information does not exist, the sending duration or number of sending resources may be configured or predefined by the network (such as a standard definition). In some embodiments, the sending duration may be, for example, the duration corresponding to one sending resource. In some embodiments, the number of sending resources may be, for example, one. That is, if this information does not exist, the terminal device may deem the sending duration to be the duration corresponding to one sending resource; alternatively, the terminal device may deem the number of sending resources to be one.

[0516] 44) Transmit power.

[0517] When the terminal device decides to send a carrier to the A-IoT device, the transmission power may be the power of the carrier. When the terminal device decides to send data / signals to the A-IoT device, the transmission power may be the power of the data / signals.

[0518] In one example, DCI-1-5 may indicate (or include) a power value or a power range of the transmission power.

[0519] In another example, DCI-1-5 may indicate (or include) an index corresponding to a power value or power range of the transmit power. That is, the power value or power range of the transmit power may be indicated by indicating an index corresponding to the power value or power range of the transmit power.

[0520] Each index may correspond to a certain power value or power range configured by the RRC layer, or in other words, the power value or power range corresponding to each index may be configured by RRC signaling.

[0521] As another example, DCI-1-5 may indicate (or include) a transmit power control command. That is, the transmit power may be indicated by the transmit power control command.

[0522] The transmit power control command may indicate an adjustment value relative to a reference transmit power, based on which the terminal device may determine the transmit power. The reference transmit power may be, for example, a transmit power last used by the terminal device (e.g., the transmit power used in the last transmission of a carrier, data, or signal).

[0523] In some embodiments, this information (transmit power) may not exist. In the absence of this information, the transmit power used by the terminal device may be the same as the current uplink transmit power, or may be the currently allowed maximum transmit power.

[0524] In some embodiments, DCI-1-5 may indicate (or include) all of the above information, that is, may indicate (or include) information 41) to 44).

[0525] In some embodiments, the terminal device (such as a higher layer of the terminal device) may decide to which A-IoT device or devices to send a carrier, or to which A-IoT device or devices to send data / signals.

[0526] In some embodiments, one or more DCIs among the above DCI-1-1 to DCI-1-5 may correspond to the same DCI format, and the number of bits of the DCI format may be configured by a network device (such as a base station). If the number of bits contained in all bit fields in the DCI format is less than the number of bits configured by the network device, zeros should be padded at the end of the DCI.

[0527] In some embodiments, in order to reduce the number of blind detections of DCIs of a terminal device, the number of bits of the DCI format can be the same as the number of bits of an uplink, downlink or sidelink DCI format currently configured by the terminal device. For DCIs with the same number of bits, different RNTIs can be used to scramble them to distinguish different DCIs.

[0528] Option 2

[0529] In solution two, the number of terminal devices (intermediate nodes) is more than one. For example, the terminal devices can be divided into a first type of terminal device and a second type of terminal device. The first terminal device in the aforementioned embodiment may, for example, belong to the first type of terminal device, and the second terminal device may, for example, belong to the second type of terminal device. Among them, the first type of terminal device and the second type of terminal device can receive DCI from a network device (such as a base station), and the first type of terminal device can send one or more of the carrier, data, and signal to the A-IoT device based on the DCI from the network device. The second type of terminal device can receive the reflected signal of the A-IoT device based on the DCI from the network device, and / or receive one or more of the carrier, data, and signal sent by the first type of terminal device.

[0530] In Solution 2, the way in which the first type of terminal device sends one or more of the carrier, data, and signal to the A-IoT device according to the DCI is the same as in Solution 1 and will not be repeated here.

[0531] In solution two, the second type of terminal device can receive a DCI sent by the network device and receive the reflected signal of the A-IoT device according to the instruction of the DCI.

[0532] In one possible approach, the DCI received by the second type of terminal device is the same as the DCI received by the first type of terminal device. That is, the network device may send the same DCI to the first type of terminal device and the second type of terminal device, and the DCI may be scrambled by an RNTI shared by the two types of terminal devices. In some embodiments, the DCI may be sent within a common physical downlink control channel (PDCCH) search space configured by the terminal device.

[0533] In another possible approach, the DCI received by the second type of terminal device is different from the DCI received by the first type of terminal device. In this case, the format of the DCI received by the second type of terminal device can be the same as the format of the DCI received by the first type of terminal device. The network device can add zeros to the end of the DCI with fewer bits to ensure that the two DCIs have the same number of bits, but the two are scrambled using different RNTIs. For example, in this case, the DCI received by the second type of terminal device can indicate at least one or more of the following information 51) to 53):

[0534] 51) Frequency of the carrier.

[0535] The carrier frequency may include: a frequency for receiving a reflected signal from an A-IoT device, and / or a frequency for receiving one or more of a carrier, data, and a signal transmitted by a first-category terminal device. The frequency for receiving a reflected signal from an A-IoT device is the frequency for receiving a carrier transmitted by the first-category terminal device.

[0536] In one example, the DCI may indicate (or include) a frequency (such as an absolute frequency) of a carrier. In some embodiments, the DCI may indicate (or include) one or more frequencies of a carrier.

[0537] In another example, the DCI may indicate (or include) an index corresponding to one or more frequencies (e.g., absolute frequencies) of a carrier. That is, one or more frequencies of a carrier may be indicated by indicating the index corresponding to one or more frequencies of the carrier. The frequency of the carrier corresponding to a certain index may be indicated, for example, by RRC signaling. In some embodiments, one index may correspond to one or more frequencies.

[0538] 52) The time when reception starts.

[0539] The time of starting to receive the reflected signal from the A-IoT device may include: the time of starting to receive the reflected signal from the A-IoT device, and / or the time of starting to receive one or more of the carrier, data, and signal sent by the first type of terminal device. The time of starting to receive the reflected signal from the A-IoT device may be the same as the time of starting to receive the carrier sent by the first type of terminal device.

[0540] In one example, the DCI may indicate (or include) the time when reception starts.

[0541] In another example, the DCI may indicate (or include) an index corresponding to the time when reception starts. That is, the time when reception starts may be indicated by indicating the index corresponding to the time when reception starts.

[0542] As another example, the DCI may indicate (or include) the time position of the resource to be received, such as the time position of the first resource to be received.

[0543] 53) Duration of reception.

[0544] The duration of reception may include: the duration of receiving the reflected signal from the A-IoT device, and / or the duration of receiving one or more of the carrier, data, and signal sent by the first type of terminal device. The duration of receiving the reflected signal from the A-IoT device may be the same as the duration of receiving the carrier sent by the first type of terminal device.

[0545] In some embodiments, the time when reception starts and the duration of reception can be jointly indicated. For example, the time when reception starts and the duration of reception can be indicated by SLIV, and each SLIV uniquely corresponds to a starting point value (the time when reception starts) and a length value (the duration of reception).

[0546] In solution two, the second type of terminal device can receive one or more of the carrier, data, and signals sent by the first type of terminal device, so as to eliminate or reduce the interference of one or more of the carrier, data, and signals sent by the first type of terminal device on the reflected signal of the A-IoT device.

[0547] Option 3

[0548] In solution three, the number of terminal devices (intermediate nodes) is one, and the terminal device can send one or more of the carrier, data, and signal to the A-IoT device based on the configuration authorization (an example of the first information) sent by the network device (such as a base station). In other words, the configuration authorization can be used by the terminal device to send one or more of the carrier, data, and signal to the A-IoT device.

[0549] For example, according to the network configuration or pre-definition (such as standard definition), the terminal device may send the configuration authorization sent by the network device in one of the following ways:

[0550] Method 5: Send carrier waves to A-IoT devices.

[0551] Method 6: Send data / signals to A-IoT devices.

[0552] Method 7: Sending a carrier wave and data / signal to an A-IoT device. For example, data / signal is sent first, followed by the carrier wave, in chronological order (method 7-1). Another example is sending the carrier wave and data / signal on different frequencies (method 7-2).

[0553] Mode 8: The terminal device decides whether to send data / signal or carrier.

[0554] Among them, sending a carrier wave refers to sending a sinusoidal electromagnetic wave of a specific frequency that does not carry data and signals.

[0555] In some embodiments, for method 5, the configuration authorization sent by the network device may at least indicate (or include) all or part of the information in DCI-1-1. In addition, the configuration authorization may also indicate (or include) the repetition period of the sending resources (the sending resources used to send the carrier).

[0556] In some embodiments, for method 6, the configuration authorization sent by the network device may at least indicate (or include) all or part of the information in DCI-1-2. In addition, the configuration authorization may also indicate (or include) the repetition period of the sending resources (sending resources used to send data / signals).

[0557] In some embodiments, for method 7-1, the configuration authorization sent by the network device may at least indicate (or include) all or part of the information in DCI-1-3. In addition, the configuration authorization may also indicate (or include) the repetition period of the sending resources (transmitting resources for sending carriers, and / or, sending resources for sending data / signals).

[0558] In some embodiments, for method 7-2, the configuration authorization sent by the network device may at least indicate (or include) all or part of the information in DCI-1-4. In addition, the configuration authorization may also indicate (or include) the repetition period of the sending resources (transmitting resources for sending carriers, and / or, sending resources for sending data / signals).

[0559] In some embodiments, for method 8, the configuration authorization sent by the network device may at least indicate (or include) all or part of the information in DCI-1-5. In addition, the configuration authorization may also indicate (or include) the repetition period of the sending resources, and whether the sending resources are used to send data / signals or to send carriers can be determined by the terminal device.

[0560] For ease of understanding, the following explanation is given using method 8 as an example.

[0561] In mode 8, after receiving the configuration authorization from the network device, the terminal device may decide whether to send data / signals or carrier waves to the A-IoT device. In this case, the configuration authorization sent by the network device to the terminal device may indicate at least one or more of the following information 61) to 65):

[0562] 61) The frequency of the carrier.

[0563] When the terminal device decides to send a carrier wave to the A-IoT device, the frequency of the carrier wave may be the frequency of the transmitting carrier wave. When the terminal device decides to send data / signals to the A-IoT device, the frequency of the carrier wave may be the frequency of the transmitting data / signals (carrier frequency).

[0564] The content or indication method of this information can refer to the description of information 41) in method 4, which will not be repeated here.

[0565] 62) The time when the sending starts, or the time position of sending the resource.

[0566] When the terminal device decides to send a carrier wave to the A-IoT device, the time of starting transmission may be the time of starting to send the carrier wave, and the time position of the transmission resource may be the time position of the transmission resource used to send the carrier wave. When the terminal device decides to send data / signals to the A-IoT device, the time of starting transmission may be the time of starting to send the data / signals, and the time position of the transmission resource may be the time position of the transmission resource used to send the data / signals.

[0567] The content or indication method of this information can refer to the description of information 42) in method 4, which will not be repeated here.

[0568] 63) The duration of the transmission, or the number of resources sent.

[0569] When the terminal device decides to send a carrier to the A-IoT device, the transmission duration may be the duration of sending the carrier, and the number of transmission resources may be the number of transmission resources used to send the carrier. When the terminal device decides to send data / signals to the A-IoT device, the transmission duration may be the duration of sending the data / signals, and the number of transmission resources may be the number of transmission resources used to send the data / signals.

[0570] The content or indication method of this information can refer to the description of information 43) in method 4, which will not be repeated here.

[0571] 64) The repetition period of the sending resource (ie, the repetition period of the sending resource in the time domain).

[0572] If the terminal device decides to send a carrier to the A-IoT device, the repetition period of the transmission resource may be the repetition period of the transmission resource used to send the carrier. If the terminal device decides to send data / signals to the A-IoT device, the repetition period of the transmission resource may be the repetition period of the transmission resource used to send data / signals.

[0573] 65) Transmit power.

[0574] When the terminal device decides to send a carrier to the A-IoT device, the transmission power may be the power of the carrier. When the terminal device decides to send data / signals to the A-IoT device, the transmission power may be the power of the data / signals.

[0575] The content or indication method of this information can refer to the description of information 44) in method 4, which will not be repeated here.

[0576] Option 4

[0577] In solution four, the number of terminal devices (intermediate nodes) is more than one. For example, the terminal devices can be divided into a first type of terminal device and a second type of terminal device. The first terminal device in the aforementioned embodiment may, for example, belong to the first type of terminal device, and the second terminal device may, for example, belong to the second type of terminal device. Among them, the first type of terminal device and the second type of terminal device can receive configuration authorization from a network device (such as a base station), and the first type of terminal device can send one or more of carriers, data, and signals to the A-IoT device based on the configuration authorization from the network device. The second type of terminal device can receive the reflected signal of the A-IoT device based on the configuration authorization from the network device, and / or receive one or more of the carriers, data, and signals sent by the first type of terminal device.

[0578] In Solution 4, the way in which the first type of terminal device sends one or more of the carrier, data, and signal to the A-IoT device based on the configuration authorization is the same as in Solution 3 and will not be repeated here.

[0579] In solution four, the second type of terminal device can receive a configuration authorization sent by the network device and receive the reflected signal of the A-IoT device according to the instruction of the configuration authorization.

[0580] In one possible manner, the configuration authorization received by the second type of terminal device is the same as the configuration authorization received by the first type of terminal device. That is, the network device may send the same configuration authorization to the first type of terminal device and the second type of terminal device.

[0581] In another possible embodiment, the configuration authorization received by the second-category terminal device is different from the configuration authorization received by the first-category terminal device. In this case, the configuration authorization received by the second-category terminal device may, for example, indicate at least one or more of the following information 71) to 73):

[0582] 71) The frequency of the carrier.

[0583] The content or indication method of this information can refer to the description of information 51) in Solution 2, which will not be repeated here.
