[0095] Internet of Things (IOT) terminals are evolving, for example, to Ambient IOT (AIOT) terminals.

[0096] AIOT is a brand new IOT technology, and a significant feature compared to traditional IOT technologies is that the number of AIOT terminals that can be connected to a network is large, and the AIOT terminals are simple in structure, low in hardware cost and maintenance cost, and low in power consumption, and can be used for a long time without replacing a battery.

[0097] 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 sensing scene of smart home, environmental monitoring, etc., that is, some data is reported under certain trigger conditions, which can be applied to the positioning scene to find items or locate in a shopping mall. It can also be used in the command scene, and a certain response is made to the command sent by the network device.

[0098] The AIOT terminal can be divided into three types:

[0099] 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.

[0100] Device B: has energy storage capability, 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.

[0101] 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.

[0102] 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 send 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.

[0103] 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 a network / intermediate node (for example, a 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 the reflected wave, 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.

[0104] 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.

[0105] For terminals with sensing functions, how to improve communication efficiency is a problem to be solved.

[0106] Therefore, the present disclosure provides a communication method, wherein a terminal transmits a first signal based on a sensing result, wherein the sensing result includes information of a target object, so as to improve the transmission reliability of the terminal and improve the communication efficiency.

[0121] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a communication method for the communication system 100, and the above method comprises:

[0122] In step S2101, the network device 102 sends first information to the terminal 101.

[0123] In some embodiments, the terminal 101 receives first information sent by the network device 102, the first information being used to configure at least one of a threshold, a set of repetition durations, etc.

[0124] In some embodiments, the network device can configure a threshold, which can be used by the terminal to determine a transmission parameter of a first signal based on a sensing result and the first threshold, and send the first signal based on the transmission parameter.

[0125] In some embodiments, the network device can configure a set of repetition durations, which can be used by the terminal to determine a repetition duration corresponding to the sensing result from the set based on the sensing result, and send the first signal based on the determined repetition duration.

[0126] In some embodiments, the name of the first information is not limited, which may, for example, be “configuration information”.

[0127] In some embodiments, the step S2101 is optional and can be omitted.

[0128] In step S2102, the terminal 101 sends a first signal based on a sensing result.

[0129] In some embodiments, the sensing result includes information of a target object, such as distance, angle between the target object and the terminal, speed of the target object, etc. The target object is an object being sensed, which may, for example, be a terminal, a building, etc.

[0130] In some embodiments, the sensing result can be a historical sensing result, i.e., a sensing result obtained by the terminal in the last time or in the previous times.

[0131] In some embodiments, the first signal is used for communication, or the first signal is used for sensing, or the first signal is used for both sensing and communication. For example, the first signal used for sensing can also be referred to as a sensing signal, the first signal used for communication can also be referred to as a communication signal, the communication signal can carry information and realize a communication function. The first signal used for both sensing and communication can also be referred to as a sensing communication signal. The first signal sent by the terminal can generate a backscattering signal when reaching a target object, or become a reflected signal, the terminal receives the backscattering signal, and determines distance, angle between the target object and the terminal, speed of the target object, etc. according to a sensing algorithm based on channel, noise statistical characteristics, etc.

[0132] In some embodiments, the waveform of the first signal has both Orthogonal Frequency Division Multiplexing (OFDM) specific characteristics and radar signal (or pulse signal) specific characteristics.

[0133] In some embodiments, the terminal can determine, based on the sensing result, a transmission parameter for transmitting the first signal, and transmit the first signal based on the transmission parameter. The transmission parameter can include at least one of a power parameter, a repetition parameter, and a beam parameter.

[0134] In some embodiments, the transmission parameter can include the power parameter. The power parameter can be used to determine a power value for transmitting the first signal. In a coverage-limited scenario, if the power value for transmitting the first signal is too small, the reliability of the transmission is low. In a non-coverage-limited scenario, if the power value for transmitting the first signal is too large, the echo signal can be interfered. Therefore, the terminal determines the transmission parameter, i.e., the power value for transmitting the first signal, according to the sensing result.

[0135] In some embodiments, the transmission parameter can include a power level, and the power level can correspond to a power value, so that the power value can be determined according to the power level.

[0136] In some embodiments, the transmission parameter can include, but is not limited to, at least one of the following: an initial power value P0, a number of occupied resource elements (REs), a power scaling factor k, and a power offset value β. P0, the number of occupied REs, k, and β can be used to calculate the power value for transmitting the first signal. For example, P0 and β can be used to calculate the power value for transmitting the first signal, i.e., the initial power value plus the power offset value. For another example, P0 and the number of REs can be used to calculate the power value for transmitting the first signal, e.g., P0 plus the logarithm (lg) of the number of REs, i.e., P0+lg(RE number). For another example, P0, the number of REs, k, and β can be used to calculate the power value for transmitting the first signal, e.g., k(P0+lg(RE number)+β). However, it can be understood that the above examples of calculation methods are only exemplary, and other calculation methods can be selected based on at least one of P0, the number of REs, k, and β to obtain the power value for transmitting the first signal, which is not limited in the present disclosure. The power parameter can also not be limited to P0, the number of REs, k, and β, but can also include other parameters, which are not limited in the present disclosure. At least one of them can be determined according to the sensing result. For example, P0 can be determined according to the sensing result, and the power value can be calculated in combination with the pre-set number of occupied REs, k, and β. For another example, P0 and the number of occupied REs can be determined according to the sensing result, and the power value can be calculated in combination with the pre-set k and β. For another example, P0, the number of occupied REs, k, and β can be determined according to the sensing result, and the power value can be calculated. The present disclosure does not enumerate all examples, but is not limited thereto.

[0137] In some embodiments, the perception result comprises a distance between the target object and the terminal; the farther the distance, the higher the power value of the first signal. For example, if the distance between the terminal and the target object is far, it can be considered as a coverage-limited scenario, therefore, the perception result comprises the distance between the terminal and the target object, and the terminal can determine the power parameter according to the distance, and determine the power value of the first signal according to the power parameter. Wherein, the farther the distance, the greater the power value of the first signal, so as to improve the reliability of transmission. Correspondingly, the closer the distance, the smaller the power value of the first signal, so as to avoid excessive power causing interference to the echo signal.

[0138] In some embodiments, the transmission parameter comprises a repetition parameter. Wherein, the repetition parameter comprises at least one of the following: whether to repeatedly send the first signal; a time length of repeatedly sending the first signal; a granularity of repeatedly sending the first signal.

[0139] In some embodiments, the repetition parameter comprises whether to repeatedly send the first signal. The terminal can determine whether to send the first signal according to the perception result. For example, the perception result comprises a distance between the target object and the terminal, and the distance is greater than or equal to a first threshold, the terminal determines to repeatedly send the first signal. Conversely, the distance is less than the first threshold, the terminal determines not to repeatedly send the first signal.

[0140] In some embodiments, the first threshold can be predefined or pre-configured by the network device.

[0141] In some embodiments, the repetition parameter comprises a time length of repeatedly sending the first signal. For example, the terminal determines to send the first signal according to the perception result, or the terminal determines to repeatedly send the first signal based on other manners. The terminal can determine the time length of repeatedly sending the first signal according to the perception result. For example, the perception result comprises a distance between the terminal and the target object, the farther the distance, the longer the time length of repeatedly sending the first signal. Conversely, the closer the distance, the shorter the time length of repeatedly sending the first signal. The time length of repeatedly sending the first signal may, for example, be a slot, for example, the terminal repeatedly sends for 4 slots. Of course, the specific time length is not limited in the present disclosure, and the above-mentioned 4 slots are only exemplary. Wherein, the terminal determines to repeatedly send the first signal based on other manners, for example, the terminal can receive an indication from the network device, and the network device instructs the terminal to repeatedly send the first signal.

[0142] In some embodiments, the network device can configure a set of time lengths for the terminal, for example, {1, 2, 3, 4}, and the terminal can determine a time length corresponding to the perception result from the set of time lengths configured by the network device according to the perception result.

[0143] In some embodiments, the repetition parameter comprises a granularity of repeating the sending of the first signal. For example, the terminal determines to send the first information according to the sensing result, or the terminal determines to repeat the sending of the first signal based on other manners. Then the terminal can determine the granularity of repeating the sending of the first signal according to the sensing result. For example, the sensing result comprises a distance between the terminal and the target object, the farther the distance, the larger the granularity of repeating the sending of the first signal. Conversely, the closer the distance, the smaller the granularity of repeating the sending of the first signal.

[0144] In some embodiments, the terminal repeats the sending of the first signal once every X wireless subframes, or the terminal repeats the sending of the first signal once every X slots, or the terminal repeats the sending of the first signal once every X mini-slots. Wherein, the wireless subframe, the slot, and the mini-slot are the granularity. The granularity of repeating the sending of the first signal comprises but is not limited to: the wireless subframe, the slot, the mini-slot, the On-Off Keying (OOK) symbol, the OFDM symbol, etc.

[0145] In some embodiments, assuming that the granularity 1 is the wireless subframe, the slot, and the mini-slot, and the granularity 2 is the slot, the mini-slot OOK symbol, and the OFDM symbol. Then the terminal can determine the granularity of repeating the sending of the first signal as the granularity 1 when the distance is greater than or equal to the fifth threshold, and determine the granularity of repeating the sending of the first signal as the granularity 2 when the distance is less than the fifth threshold.

[0146] In some embodiments, the transmission parameter comprises a beam parameter. The beam parameter comprises at least one of: a number of beams; a polarization direction of the beam; the beam is a wide beam or a narrow beam; the beam is a directional beam or an omnidirectional beam.

[0147] In some embodiments, the beam parameter comprises the number of beams, and the sensing result comprises a distance between the terminal and the target object. The farther the distance, the more the number of beams determined by the terminal. That is, the farther the distance between the terminal and the target object, the more the number of beams used by the terminal to send the first signal. Conversely, the closer the distance between the terminal and the target object, the less the number of beams used by the terminal to send the first signal.

[0148] In some embodiments, the beam parameter comprises a polarization direction of the beam. The sensing result comprises a distance between the terminal and the target object. When the distance is greater than or equal to the second threshold, the polarization direction of the beam is linear polarization. That is, when the distance is greater than or equal to the second threshold, the terminal uses the beam with the linear polarization direction to send the first signal to improve the transmission reliability. Conversely, when the distance is less than the second threshold, the polarization direction of the beam is circular polarization. That is, when the distance is less than the second threshold, the terminal uses the beam with the circular polarization direction to send the first signal to increase the coverage area.

[0149] In some embodiments, the beam parameter includes that the beam is a wide beam or a narrow beam. The perception result includes the distance between the terminal and the target object, and a communication path between the target object and the terminal. When the distance is greater than or equal to a third threshold value, and / or the communication path is a non-line-of-sight (NLOS) path, the beam is a narrow beam. That is, when the distance is greater than or equal to the third threshold value, and / or the communication path is an NLOS path, the terminal transmits the first signal using a narrow beam to improve transmission reliability. Conversely, when the distance is less than the third threshold value, and / or the communication path is a line-of-sight (LOS) path, the beam is a wide beam. That is, when the distance is less than the third threshold value, and / or the communication path is an LOS path, the terminal transmits the first signal using a wide beam to increase the coverage area.

[0150] In some embodiments, the beam parameter includes that the beam is a directional beam or an omnidirectional beam. The perception result includes the distance between the terminal and the target object. When the distance is greater than or equal to a fourth threshold value, the beam used to transmit the first signal is a directional beam to improve transmission reliability. Conversely, when the distance is less than the fourth threshold value, the beam used to transmit the first signal is an omnidirectional beam to increase the coverage area.

[0151] In some embodiments, whether the communication path is an NLOS path or an LOS path can be determined based on the angle between the terminal and the target object.

[0152] In some embodiments, each threshold value can be predefined or pre-configured by the network device. For example, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value, and the like.

[0153] In some embodiments, the first signal transmitted by the terminal 101 can be transmitted to the network device 102, or to the terminal 103, or to other target objects such as buildings, and the like.

[0154] In step S2103, the terminal 101 transmits the transmission parameter to the network device 102.

[0155] In some embodiments, the network device 102 receives the transmission parameter transmitted by the terminal 101. The transmission parameter includes the transmission parameter of the terminal transmitting the first signal.

[0156] In some embodiments, the terminal can determine the transmission parameter of transmitting the first signal according to the perception result, and report the transmission parameter to the network device, so that the network device knows the transmission parameter used by the terminal to transmit the first signal.

[0191] The optional implementation of step S5101 can refer to S2102 in FIG.2, and other associated parts in the embodiments involved in FIG.2, which will not be repeated here.

[0192] The present disclosure provides a communication method, which is as follows:

[0193] In some embodiments, the terminal determines the power of the signal sent by the terminal according to the determined sensing information. The sensing information can be the sensing result in the above embodiments, and the two can be used alternatively.

[0194] In some embodiments, the distance information determined by the terminal is used to determine the power level of the signal sent by the terminal next time or several times, and a corresponding relationship table between the transmission power level and the sensed distance is pre-configured or pre-defined.

[0195] In some embodiments, the terminal receives the echo signal, and determines the sensed distance information according to the sensing algorithm according to the channel, noise statistical characteristics, etc. The farther the sensed distance is, the higher the transmission power level is selected. According to the corresponding table of the sensing distance and the transmission power level, it is determined that the corresponding transmission power level at the distance is level 5, and then the transmission power level 5 is used to send signaling or data. The terms such as sensing distance information, sensing distance, and sensing distance all represent the distance between the terminal and the target object.

[0196] In some embodiments, the terminal determines the perceived distance information to determine the power parameter value of the terminal to transmit the signal in the next or several communications. The correspondence table between the power parameter value and the perceived distance is pre-configured or pre-defined.

[0197] In some embodiments, the terminal determines the perceived distance information, and the farther the perceived distance, the higher the power parameter value selected to make the terminal's final transmission power. The transmission power of the terminal is related to the following parameters: initial power value P0, the number of occupied resource units, power scaling factor k, and power offset value β. When the determined perceived distance is farther, the initial power value P0, and / or the power scaling factor k, and / or the power offset value β are larger according to the correspondence table between the parameter value and the perceived distance.

[0198] In some embodiments, the terminal determines whether to repeat transmission according to the determined perceived information, and / or the length of repeated transmission, and / or the repetition granularity.

[0199] In some embodiments, the terminal determines whether to repeat transmission in the next or several communications according to the determined perceived information. When the determined perceived information indicates that the target terminal to be communicated is farther away from the terminal, and is greater than or equal to a pre-configured or pre-defined or dynamically indicated distance threshold 1, it is possible that the coverage is limited, and the terminal determines to use repeated transmission when transmitting the signal. Otherwise, the terminal does not use repeated transmission.

[0200] In some embodiments, the terminal determines the repetition granularity of the terminal according to the determined perceived information. When the determined perceived information indicates that the target terminal to be communicated is farther away from the terminal, and is greater than or equal to a pre-configured or pre-defined or dynamically indicated distance threshold 1, it is possible that the coverage is limited, and the terminal determines to use repeated transmission when transmitting the signal, and is greater than or equal to a pre-configured or pre-defined or dynamically indicated distance threshold 2, i.e., the determined repetition granularity is granularity 1. Otherwise, the determined repetition granularity is granularity 2. Granularity 1 is larger than granularity 2, and granularity 1 can be a radio subframe, a time slot, a micro time slot, and granularity 2 can be a time slot, a micro time slot, an OOK symbol, an OFDM symbol, etc.

[0201] In some embodiments, the terminal determines the length of repeated transmission according to the determined perceived information. When the determined perceived information indicates that the target terminal to be communicated is farther away from the terminal, and the coverage is limited, the terminal determines to use repeated transmission when transmitting the signal, and determines that the repetition granularity is slot level. The correspondence table between the pre-defined or pre-configured distance and the repetition length is pre-configured, such as a pre-configured repetition length set {1, 2, 3, 4}. When the determined perceived distance corresponds to a repetition length parameter value of 4, the terminal determines to use 4-slot repeated transmission.

[0202] In some embodiments, the terminal determines the number of beams, and / or the polarization direction of the beams, and / or the width of the beams, and / or the direction of the beams, or omni-directional beams, etc. used by the terminal when transmitting the signal according to the determined perceived information.

[0203] In some embodiments, according to the determined perceived distance information and / or angle information, when the terminal determines that the distance between the target communication terminal and the perception receiving terminal reaches a distance threshold, and according to the perceived angle information, it is determined that there is an NLOS path at the target communication terminal, then the terminal uses a narrow beam when transmitting the signal, otherwise a wide beam is used.

[0204] In some embodiments, according to the determined perceived distance and / or angle information, if the target terminal is determined to be far away from the perception receiving terminal by the sensing calculation, then a larger number of beams are used when transmitting the signal, such as a pre-configured or pre-defined corresponding relationship table of perceived distance information and beam number, then the perception receiving terminal determines that the distance to the target communication terminal reaches a pre-defined or pre-configured threshold 1, and the beam number corresponding to the distance threshold 1 is N, then it is determined that N beams are used when transmitting the signal.

[0205] In some embodiments, the perception information can include the following information: distance, speed, angle, etc.

[0206] In some embodiments, the signal refers to a sensing communication signal (a signal carrying information, used for both sensing and communication functions) transmitted by the terminal. After the target in the surrounding environment receives the communication sensing signal, a backwave signal is generated. The terminal determines the distance, angle, speed, etc. of the target in the surrounding environment according to the received backwave signal and the transmitted sensing communication signal, channel, noise statistical characteristics, etc. according to the sensing algorithm. For example, the waveform of the sensing communication signal has the characteristics of OFDM and radar signal (pulse signal). It can also refer to two signals: sensing signal and communication signal. The sensing signal is used for sensing purposes, and the communication signal is used for communication functions, carrying information. The terminal determines the distance, angle, speed, etc. of the target in the surrounding environment according to the received backwave signal and the transmitted sensing signal, channel, noise statistical characteristics, etc. according to the sensing algorithm. For example, the waveform of the sensing signal has the characteristics of radar signal (pulse signal).

[0212] In some embodiments, the sensing result comprises a distance between the target object and the terminal. The farther the distance, the higher the power value for transmitting the first signal.
