[0133] IOT can be applied to the scene of inventorying a large number of items, that is, the AIOT device reports the Evolved Packet Core (EPC) code to the network or intermediate node X or UE, which can be applied to the smart home, environmental monitoring and other sensing scenarios, that is, it meets certain trigger conditions and reports some data, which can be applied to the positioning scene to find items or locate in the mall. It can also be used in the command scene, and a certain response is made to the command sent by the network device.

[0134] The AIOT terminal can be divided into three types:

[0135] Device A: cannot independently generate / amplify signals, for example, uses a backscattering working mode. It does not have the ability to amplify DL and / or UL signals.

[0136] Device B: has energy storage capability and cannot independently generate signals, for example, uses a backscattering working mode. It can use stored energy for downlink (DL) and / or uplink (UL) signal amplification. Device A / B may use a relatively simple modulation and demodulation method, such as binary on-off keying (OOK) / phase shift keying (PSK), etc.

[0137] Device C: has energy storage capability and can independently generate signals, for example, has an active signal transmitting radio frequency (RF) module. Device C can also use a high-complexity modulation and demodulation method, such as orthogonal frequency division multiplexing (OFDM) modulation and demodulation. It can amplify uplink or downlink signals.

[0138] Among the above three terminal types, Device C has the strongest capability and the highest terminal cost. Device A has the weakest capability and the lowest terminal cost. In addition, Device A and B can only use a backscattering working mode and cannot actively transmit signals. When they need to transmit information, they must have external electromagnetic waves (continuous wave, CW) for backscattering. The terminal coverage they can support is smaller, but the power consumption of the working mode of Device A / B is much smaller than that of Device C.

[0139] The AIOT device works based on backscatter. For a Device using the backscatter mode, the Device needs to have an energy source (CW node) providing a continuous wave (CW) to provide electromagnetic waves for reflection while transmitting data. The CW is generally constant in amplitude. The CW node can be a separate node or just a network / intermediate node (e.g., UE) in communication with the Device. The AIOT device reflects the received CW, loads the signaling / data to be transmitted onto the reflected wave and transmits it, and the reflected wave is the same frequency as the CW or has a certain frequency offset. At the same time, the CW also serves to charge the AIOT device. The Type A device receives the wireless signal CW, activates the internal receiving processing module to start working, and encodes and modulates the signaling / data to be uploaded by the AIOT device.

[0140] The AIOT terminal can also be referred to as an AIOT device, and the AIOT terminal and the A-IoT terminal have the same meaning and can be used interchangeably.

[0141] Therefore, in order to further improve the communication efficiency, the present disclosure provides a communication method, wherein a first terminal transmits a sensing signal, wherein the sensing signal is used to sense the information of a target object, so as to realize the integration of sensing communication of the terminal and improve the communication efficiency.

[0155] FIG. 2a is a schematic diagram of an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2a, the embodiment of the present disclosure relates to a communication method for the communication system 100, and the above method comprises:

[0156] In step S2101, the first terminal 101 transmits a sensing signal.

[0157] In some embodiments, the first terminal can send a sensing signal, the sensing signal being used to sense information of the target object.

[0158] In some embodiments, the first terminal sending the sensing signal can include that the first terminal sends the sensing signal based on a period. That is, the first terminal can periodically send the sensing signal to avoid sending the sensing signal all the time, causing excessive power consumption. Especially when the first terminal is an IOT terminal, the power consumption of the IOT terminal for communication and sensing integration is usually low, and therefore, by periodically sending the sensing signal, excessive power consumption can be avoided.

[0159] In some embodiments, the period of the first terminal sending the sensing signal can be determined in at least one of the following manners: based on a configuration of the network device; based on a protocol, the protocol defining the period.

[0160] Optionally, the first terminal can determine the period of sending the sensing signal based on a configuration of the network device. For example, the network device can pre-configure a period. One period can be pre-configured, and the terminal can send the sensing signal based on the period. Multiple periods can also be pre-configured, and the terminal can send the sensing signal based on one of the periods according to actual conditions, for example, when the terminal has more remaining power, a relatively shorter period is selected to send the sensing signal, and when the terminal has less remaining power, a relatively longer period is selected to send the sensing signal. The network device can also activate one of the periods by sending an activation message after pre-configuring multiple periods. For another example, the network device can dynamically configure the period, that is, the network device can configure different periods at different times and in different scenarios.

[0161] Optionally, the first terminal can determine the period of sending the sensing signal based on a protocol. For example, the protocol defines the period of sending the sensing signal.

[0162] In some embodiments, if the first terminal determines the period of sending the sensing signal based on a configuration of the network device, the network device can configure the period in at least one of the following manners: the network device can configure the period through radio resource control (RRC) signaling; the network device can configure the period through physical layer control signaling; the network device can configure the period of the sensing signal through system message.

[0163] In some embodiments, the first terminal sending the sensing signal can include that the first terminal receives first information sent by the network device, and sends the sensing signal based on a time and / or duration indicated by the first information. The first information is used to indicate the time and / or duration of sending the sensing signal. That is, the network device can indicate the first terminal to send the sensing signal at what time and for how long, to avoid the first terminal sending the sensing signal all the time, causing excessive power consumption.

[0164] In some embodiments, the first information can be used to indicate a time for transmitting the sensing signal, and the first information comprises at least one of: a radio frame; a time slot; a symbol. That is, the first information can jointly indicate the time for transmitting the sensing signal by at least one of the radio frame, the time slot, and the symbol. After receiving the first information, the first terminal can transmit the sensing signal in the corresponding radio frame, time slot, or symbol.

[0165] In some embodiments, the first information is used to indicate the time for transmitting the sensing signal, and the first information comprises an offset value, which represents an offset between a time when the first terminal receives the first information and a time when the first terminal transmits the sensing signal. After receiving the first information, the first terminal can determine the time for transmitting the sensing signal according to the time when the first information is received plus the offset value.

[0166] Of course, the first information can also be used to indicate a specific time, for example, to indicate that the first terminal transmits the sensing signal in the morning or in the afternoon every day, and the present disclosure does not limit this.

[0167] In some embodiments, the first information is used to indicate a duration for transmitting the sensing signal, and the first information comprises an index of the duration, which is used to indicate one of a plurality of durations pre-configured by the network device. That is, the network device can pre-configure a plurality of durations, and indicate one of the durations as the duration for transmitting the sensing signal by the first information.

[0168] In some embodiments, the first information is used to indicate a duration for transmitting the sensing signal, and the first information comprises an absolute value of the duration. The absolute value can be understood as an actual value rather than a mapping value. The first information can also indicate a mapping value, such as the index in the above embodiments. In some embodiments, the first information can be carried by physical layer control signaling. For example, the network device dynamically indicates in the physical layer control signaling that the offset value of the sensing signal start time relative to the time slot (slot) n of the physical layer control signaling is 5 time slots, that is, the terminal starts to transmit the sensing signal 5 time slots after receiving the time slot n of the control signaling, and indicates that the duration is 2 time slots, that is, the terminal starts to transmit the sensing signal at time slot n+5 and the transmission duration is 2 time slots.

[0169] In some embodiments, the first terminal transmitting the sensing signal can comprise: the first terminal receiving second information transmitted by the second terminal, and transmitting the sensing signal based on the second information. The second information is used to request the sensing information transmitted by the first terminal. That is, the first terminal transmits the sensing signal when receiving the request of the second terminal, and can not transmit the sensing signal to save power consumption when not receiving the request of the second terminal.

[0170] In some embodiments, the first terminal sending the sensing signal can comprise: the first terminal sending third information to the second terminal, the third information being used to request the second terminal to send the sensing signal. For example, when the remaining power of the first terminal is lower than a threshold, the third information can be sent to the second terminal to request the second terminal to send the sensing signal.

[0171] In some embodiments, the third information comprises at least one of: an identifier of the first terminal; an identifier of the second terminal; a group identifier of a group in which the second terminal is located. For example, the third information comprises the identifier of the first terminal and the identifier of the second terminal, i.e. instructs the terminal identified by the identifier of the first terminal to request the terminal identified by the identifier of the second terminal to send the sensing signal. For another example, the third information comprises the identifier of the first terminal and the group identifier of the group in which the second terminal is located, i.e. instructs the terminal identified by the identifier of the first terminal to send the sensing signal to the terminal in the group identified by the group identifier, e.g. the second terminal. For example, in the third information, there are fields including the identifier of the first terminal, the identifier of the second terminal, the identifier of the group in which the second terminal is located, etc. Illustratively, the terminal 1 corresponding to the identifier 1 carries the sensing request information field with a bit value of 1, the terminal identifier 2 information field in the physical layer control signaling, and after receiving and decoding the control signaling, the terminal identifier 2 starts to send the sensing signal on the periodic resource configured by the network, the periodic value is 10s, on K continuous or discrete frequency domain resource units, the sending duration is 2 time slots, and the sensing signal starts to be sent with a period of 10s and a duration of 2 time slots.

[0172] In some embodiments, the third information can further comprise a field of the sensing request information, e.g. a 1-bit sensing request information field, a bit value of 1 indicating a request to send the sensing signal, and a bit value of 0 indicating no request to send the sensing signal.

[0173] In some embodiments, the resource for the first terminal to send the sensing signal is determined in at least one of the following ways: based on the configuration of the network device; based on a protocol in which a period is defined. For example, the resource can comprise time domain, frequency domain, code domain, space domain, etc. resources dedicated to sending the sensing signal. The time domain resource can be, for example, absolute time, time slot, micro time slot, symbol, OFDM symbol, OOK symbol, PIE symbol, etc. Taking the first terminal sending the sensing signal based on a period as an example, the network device can configure the period, and can also configure the resource. For example, the network device configures the first terminal to send the sensing signal with a period of 10 seconds (s), on K continuous frequency domain resources, and on 2 time slots, but the disclosure is only an example and is not limited thereto.

[0174] In some embodiments, the sensing signal sent by the first terminal can include a signal dedicated to sensing. It can also be a reference signal in NR. For example, a Demodulation Reference Signal (DMRS), a Sounding Reference Signal (SRS), etc., but not limited thereto.

[0175] In some embodiments, if the first terminal sends a downlink spectrum, the first terminal can multiplex a downlink reference signal in NR. For example, a DMRS, a Channel State Information-Reference Signal (CSI-RS), a Phase-tracking reference signal (PTRS), a Positioning Reference Signal (PRS), a Mobile Reference Signal (MRS), and a Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS).

[0176] In some embodiments, the waveform of the sensing signal sent by the first terminal can include at least one of the following: an OFDM waveform; a waveform obtained by superimposing an OFDM waveform and a pulse waveform with a weight. The waveform obtained by superimposing an OFDM waveform and a pulse waveform with a weight can mean a waveform obtained by superimposing a frequency of an OFDM waveform multiplied by a weight and a frequency of a pulse waveform multiplied by a weight, and / or a waveform obtained by superimposing an amplitude of an OFDM waveform multiplied by a weight and an amplitude of a pulse waveform multiplied by a weight. The weight of the OFDM waveform and the weight of the pulse waveform can be set according to actual conditions, and the present disclosure is not limited thereto. For example, when the weight of the OFDM waveform is A%, the weight of the pulse waveform is 1-A%. The pulse waveform can also be a continuous waveform. That is, the waveform of the sensing signal can include a waveform obtained by superimposing an OFDM waveform and a continuous waveform with a weight.

[0177] In some embodiments, the sequence of the sensing signal sent by the first terminal can be a sequence dedicated to sensing. It can also be a ZC sequence (the ZC sequence refers to a non-binary unit amplitude sequence), a gold sequence (the gold sequence refers to a pseudo-random sequence), a maximum linear feedback shift register (M) sequence, a Frank sequence, etc., but not limited thereto.

[0178] In step S2102, the first terminal 101 receives an echo signal of the sensing signal.

[0179] In some embodiments, when the sensing signal sent by the first terminal reaches the target object, a back echo signal, also known as a reflected signal, is generated, and the first terminal receives the back echo signal, so that information of the target object can be obtained. For example, but not limited to, the information of the target object includes speed, angle, distance, etc. The target object may, for example, be a terminal, a building, etc.

[0180] In some embodiments, if the first terminal 101 receives the second information sent by the second terminal, and sends the sensing signal based on the second information, after receiving the back echo signal, the first terminal 101 can feed back the information of the target object to the second terminal.

[0201] In some embodiments, the second terminal 103 receives the third information sent by the first terminal 101.

For example, when the remaining power of the first terminal is lower than a threshold, the third information can be sent to the second terminal to request the second terminal to send the sensing signal instead of the first terminal.

[0276] In some embodiments, the IoT terminal transmits the sensing signal on a resource pre-configured or pre-defined by the network device with a period p.

[0277] In some embodiments, the period p can be pre-configured or pre-defined by the network device and notified to the terminal through RRC signaling. Or the period p can be notified to the terminal by the network device in physical layer control information.

[0298] In some embodiments, the terminal ID information field includes the terminal ID 1 requesting to send the sensing signal, and / or the terminal ID 2 receiving the request and sending the sensing signal, that is, the IoT terminal 1 corresponding to ID 1 requests the IoT terminal corresponding to ID 2 to send the sensing signal.

[0299] In some embodiments, the terminal receiving the request and sending the sensing signal sends the sensing signal on the network device pre-configured or pre-defined resource.

[0300] Optionally, after receiving the request to send the sensing signal, the other IoT terminal can periodically send the sensing signal, and the cycle value can be determined using the same method as the above core invention point 1.
