Optionally, the relay device is a satellite, a ground relay or other device with relay function. Optionally, the relay device expands the coverage range, so that the network device can cover more terminals for communication.

[0139] In some embodiments, the present disclosure proposes a new communication technology (ISAC technology) as a breakthrough in 5G and / or 6G. It aims to integrate sensing capability into the design of communication systems, so that the communication system can provide sensing as a service to users together with communication.

[0140] Optionally, the ISAC technology is applied in centralized TRP-TRP bistatic, TRP monostatic, TRP-UE bistatic, UE-TRP bistatic, UE-UE bistatic, UE monostatic, etc. In the design process of the ISAC system, the business requirements of communication and sensing need to be considered at the same time.

[0141] Optionally, the base station is self-transmitting and self-receiving (i.e., TRP monostatic). The base station transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the base station receives and measures the reflected / scattered wave.

[0142] Optionally, the base station A transmits and the base station B receives (i.e., TRP-TRP bistatic). The base station A transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the base station B receives and measures the reflected / scattered wave.

[0143] Optionally, the terminal transmits and the base station receives (i.e., UE-TRP bistatic). The terminal transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the base station receives and measures the reflected / scattered wave.

[0144] Optionally, the base station transmits and the terminal receives (i.e., TRP-UE bistatic). The base station transmits a sensing signal, and after the sensing signal is reflected by the measured object, the terminal receives and measures the reflected / scattered wave.

[0145] Optionally, the terminal is self-transmitting and self-receiving (i.e., UE monostatic). The terminal transmits a sensing signal, and after the sensing signal passes through the environment or objects in the environment, the terminal receives and measures the reflected / scattered wave.

[0146] Optionally, terminal A transmits and terminal B receives (i.e. UE-UE bistatic). Terminal A transmits a sensing signal, and terminal B receives and measures the reflected / scattered wave after the signal passes through the environment or objects in the environment.

[0147] In some embodiments, the speed of the target object can be determined based on radar sensing principles. In which, the speed of the target object can be determined when the radar transmitted signal has phase continuity. Optionally, if the phase of any two transmitted pulses is consistent, the radar is coherent, and if the radar can maintain an integer number of wavelengths between the equal phase wavefront at the end of one pulse and the equal phase wavefront at the front of the next pulse, the radar is coherent. Optionally, coherence also refers to the radar's ability to accurately measure (extract) the phase of the received signal. Since Doppler represents the frequency shift in the received signal, only coherent or receiving coherent radar can extract Doppler information. In which, the instantaneous frequency of the signal is proportional to the time derivative of the signal phase. For example, a radar system using a main oscillator amplifier type transmitter is coherent. The main oscillator provides a continuous wave, and the pulses of the main oscillator are actually "cut" from the continuous wave, so there is a certain phase relationship between the intercepted pulse trains. In some embodiments, if the clock of the keying switch is generated based on the oscillator as the clock reference, the pulses are coherent. For pulsed signals, coherence (also known as coherence) refers to the consistency or continuity of the phase from one pulse to the next.

[0148] FIG. 2 is an interaction diagram illustrating a method for indicating signal processing capability of phase continuity, according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a method for indicating signal processing capability of phase continuity, and the method comprises:

[0149] In step S2101, the first node transmits first information.

[0150] In some embodiments, the first information is used to indicate the capability of the first node to transmit a signal with phase continuity. Alternatively, it can also be understood that the first information is used to indicate that the first node has a certain capability, which is the capability to transmit a signal with phase continuity. Alternatively, it can also be understood that the first information is used to indicate that the first node can transmit a signal with phase continuity.

[0151] In some embodiments, the phase continuity can also be understood as phase coherence.

[0152] In some embodiments, the signal with phase continuity is used for sensing a device. Alternatively, the signal with phase continuity can also be used for measuring the speed of an object. Alternatively, it can also be used for other processing, which is not limited by the embodiments of the present disclosure.

[0153] In some embodiments, the first node refers to a terminal or a base station. For example, the first node is a terminal, and the step S2101 is sending the first information by the terminal. For another example, the first node is a base station, and the step S2101 is sending the first information by the base station.

[0154] In some embodiments, the first node sending the first information can also be understood as the first node sending the first information to a network device. Optionally, the network device is one network element in a core network device, and the embodiments of the present disclosure are not limited thereto.

[0155] In some embodiments, the first information is used to indicate that the first node has the capability of sending signals with phase continuity in any two time periods. In the embodiments of the present disclosure, the signals sent by the first node have phase continuity in any time period, or can also be understood as the signals sent by the first node can always maintain phase continuity. Correspondingly, when the second node receives the signals sent by the first node, the received signals also always maintain phase continuity.

[0156] In some embodiments, the signals with phase continuity include a first signal and a second signal, and the starting phase of the second signal is expressed by the following formula: p2=(p1+(t2-t1)*f*2π)%2π

[0157] wherein, % is the modulo symbol, t1 is the ending time of the first signal, p1 is the phase at t1, t2 is the starting time of the second signal, and f is the frequency of the sensing signal. The frequencies of the first signal and the second signal are both f.

[0158] In some embodiments, the first information is used to indicate that the first signal and the second signal with a specific condition have phase continuity; wherein the specific condition is that the time domain interval of the first signal and the second signal does not exceed a specific window length. Optionally, the above scheme can also be understood as the first information is used to indicate that the first node has the capability of sending the first signal and the second signal with a time interval less than a first length, and the first signal and the second signal have phase continuity. Optionally, the sending time of the first signal is before the sending time of the second signal. In the embodiments of the present disclosure, the first node can send the first signal and the second signal, and if the interval length between the sending time of the first signal and the sending time of the second signal is less than the first length, the first signal and the second signal have phase continuity.

[0159] Optionally, the first length is agreed by a communication protocol, or configured by a network device, or configured in other manners, and the embodiments of the present disclosure are not limited thereto.

[0160] In some embodiments, the specific relationship is expressed by the following formula: |p2-(p1+t Δ *f*2π)%2π|≤P Threshold

[0161] wherein % is a remainder symbol, t1 is an ending time of the first signal, p1 is a phase at the time t1, t2 is a starting time of the second signal, f is a frequency of the perception signal, P Threshold is a phase deviation threshold value, t Δ is an interval between the ending time of the first signal and the starting time of the second signal, the t Δ is less than the first time length.

[0162] It should be noted that the above embodiment is described by taking the interval between the first signal and the second signal not exceeding the first time length as an example. In another embodiment, there is also a case that the interval between the first signal and the second signal exceeds the first time length, in which case the first signal and the second signal do not have phase consistency. Alternatively, the relationship between the ending phase of the first signal and the starting phase of the second signal is expressed by the following formula: |p2-(p1+t Δ *f*2π)%2π|>P Threshold

[0163] wherein % is a remainder symbol, t1 is an ending time of the first signal, p1 is a phase at the time t1, t2 is a starting time of the second signal, f is a frequency of the perception signal, P Threshold is a phase deviation threshold value, t Δ is an interval between the ending time of the first signal and the starting time of the second signal, the t Δ is less than the first time length. Alternatively, P Threshold is 0, or P Threshold is other numerical value, which is not limited in the embodiments of the present disclosure.

[0164] In some embodiments, the first node supports multiple time lengths, wherein the first time length is any one of the multiple time lengths. Alternatively, the first node supports multiple working modes, each working mode corresponding to a first time length. Or, it can also be understood that the working mode supported by the first node corresponds to the first time length one by one. For example, the first node supports working mode 1, working mode 2 and working mode 3, working mode 1 corresponds to first time length A, working mode 2 corresponds to first time length B, and working mode 3 corresponds to first time length C.

[0165] In another embodiment, the first node supports multiple first time lengths, and different first time lengths correspond to different hardware, software and energy consumption of the first node. For example, a larger first time length corresponds to higher hardware resource overhead and also corresponds to larger energy consumption.

[0166] In some embodiments, there can or can not be other signals between the two signals sent by the first node, and whether the two signals have phase continuity can also be different for different cases, which are described below.

[0167] Optionally, the capability of sending the phase continuity signal comprises:

[0168] (1) The time period between the first signal and the second signal does not include a time period of the uplink signal or the uplink channel, and the first signal and the second signal have phase continuity. Alternatively, it can also be understood that if there is no uplink signal or uplink channel between the first signal and the second signal, the first signal and the second signal have phase continuity.

[0169] It should be noted that the above embodiments are described in the case where the first signal and the second signal have phase continuity. In another embodiment, the time period between the first signal and the second signal includes a time period of the uplink signal or the uplink channel, and the first signal and the second signal do not have phase continuity. Alternatively, it can also be understood that if there is an uplink signal or an uplink channel between the first signal and the second signal, the first signal and the second signal do not have phase continuity.

[0170] (2) The time period between the first signal and the second signal includes other downlink signals, and the phase of the other downlink signals has continuity with the phase of the previous one of the first signal and the second signal, and the first signal and the second signal have phase continuity. Alternatively, it can also be understood that if there are other downlink signals between the first signal and the second signal, and the phase of the other downlink signals has continuity with the phase of the previous one of the first signal and the second signal, the first signal and the second signal have phase continuity.

[0171] For example, if there is a downlink signal after the first signal and before the second signal, if there is phase continuity between the first signal and the downlink signal, there is also phase continuity between the first signal and the second signal.

[0172] (3) The time period between the first signal and the second signal includes other downlink signals, and the phase of the other downlink signals does not have continuity with the phase of the previous one of the first signal and the second signal, and the first signal and the second signal do not have phase continuity. Alternatively, it can also be understood that if there are other downlink signals between the first signal and the second signal, and the phase of the other downlink signals does not have continuity with the phase of the previous one of the first signal and the second signal, the first signal and the second signal do not have phase continuity.

[0173] In some embodiments, the first information is used to indicate that the first node does not have the capability of sending a signal with phase continuity.

[0174] In some embodiments, the first information is used to indicate that the first node has the capability of transmitting a signal with phase continuity within an arbitrary bandwidth. In the embodiments of the present disclosure, the signal transmitted by the first node has phase continuity within the arbitrary bandwidth, or can also be understood as that the signal transmitted by the first node can always maintain phase continuity within the arbitrary bandwidth. Correspondingly, when the second node receives the signal transmitted by the first node, the received signal also always maintains phase continuity within the bandwidth.

[0175] In some embodiments, the first information is used to indicate that the first node has the capability of transmitting a signal with phase continuity within a first bandwidth. Optionally, the first bandwidth is agreed by a communication protocol, or is configured by a network device, or is configured in other manners, which is not limited in the embodiments of the present disclosure.

[0176] Optionally, the first bandwidth is an absolute width value of a frequency domain bandwidth. Or, the first bandwidth is a plurality of carriers included in a specific band. Or, the first bandwidth is a combination of a plurality of specific bands. Or, the first bandwidth is FR1 and FR2. For example, a transceiver link used by band1 and band2 is the same, and the signals on band1 and band2 have phase continuity.

[0177] It should be noted that the bandwidth of the signal in the embodiments of the present disclosure is contained in the first bandwidth of the first node, so as to ensure that the entire frequency band of the signal can be used for subsequent processing.

[0178] In step S2102, the network device receives first information.

[0179] In the embodiments of the present disclosure, after the network device receives the first information, the capability of the first node can be determined based on the first information.

[0180] In step S2103, the network device transmits second information.

[0181] In some embodiments, the second information is used to indicate the capability of the first node. It should be noted that the embodiments of the present disclosure are described by taking the second information as an example. In some embodiments, the second information can be understood as the first information, that is, the network device forwards the first information to the second node.

[0182] In some embodiments, the network device transmits the second information to the second node.

[0183] In step S2104, the second node receives the second information.

[0184] In the embodiments of the present disclosure, after the second node receives the second information, the capability of the first node can be determined based on the second information, and then it is determined whether the received signal has continuity.

[0185] In step S2105, the first node sends the signal with phase continuity.

[0186] In the embodiments of the present disclosure, the first node sends the signal based on its capability, and the sent signal has phase continuity.

[0187] In step S2106, the second node receives the signal with phase continuity.

[0188] In step S2107, the second node performs coherent operation based on the received signal.

[0189] In some embodiments, the second node is a terminal, a base station or other device, which is not limited in the embodiments of the present disclosure.

[0190] In some embodiments, the coherent operation is performed based on the received signal if the received signal has phase continuity. Optionally, the coherent operation includes Doppler shift or other operation, which is not limited in the embodiments of the present disclosure.

[0191] In some embodiments, if the first information received by the second node indicates that the first node has the capability of sending signals with phase continuity in any two time periods, the coherent operation can be performed on any two signals with interval.

[0192] In some embodiments, if the first information is used to indicate that the first node has the capability of sending the first signal and the second signal with phase continuity and the time interval of the first signal and the second signal is less than the first time length, the coherent operation can be performed on the signals in the window corresponding to the first time length.

[0193] In some embodiments, if the first information is used to indicate that the first node does not have the capability of sending signals with phase continuity, the coherent operation is not performed on the received signal.

[0194] In some embodiments, if the first information is used to indicate that the first node has the capability of sending signals with phase continuity in any bandwidth, the coherent operation can be performed on any two signals in the frequency domain.

[0195] In some embodiments, if the first information is used to indicate that the first node has the capability of sending signals with phase continuity in the first bandwidth, the coherent operation can be performed on the signals in the first bandwidth.

[0196] It should be noted that the embodiments of the present disclosure are to realize the capability sharing between the network device and the second node through the second information, and in another embodiment, steps S2103-S2104 can also not be performed, and the phase continuity of the received signal is determined through the communication protocol.

[0197] It should be noted that if the second node performs coherent operation on the received signal, the parameter indicated by the signal can be obtained based on the signal after the coherent operation. For example, the parameter indicated is the distance between the first node and the second node, the speed of the second node, etc., which is not limited by the embodiments of the present disclosure.

[0198] For example, the second node defaults that the signal sent by the first node has phase continuity in the time domain at all times. Alternatively, the second node defaults that the signal sent by the first node has phase continuity within a first time length. Alternatively, the second node defaults that the signal sent by the first node does not have phase continuity.

[0199] For example, the second node defaults that the signal sent by the first node has phase continuity in the frequency domain at all times. Alternatively, the second node defaults that the signal sent by the first node has phase continuity within a first bandwidth. For example, the first bandwidth is 400 MHz.

[0280] FIG. 7 is a flowchart of a method for indicating a signal processing capability of phase continuity according to an embodiment of the present disclosure. As shown in FIG. 7, the embodiment of the present disclosure relates to a method for indicating a signal processing capability of phase continuity, and the above method comprises:

[0281] Step S7101: The Tx Node (BS / UE) reports the signal phase continuity capability of the Tx Node to the network (SF).

[0282] a) In some embodiments, capability 1: the phase continuity can be maintained all the time

[0283] i. It can be understood that the receiving end has a certain phase relationship between the reception of the two sensing signals in any two time periods.

[0284] ii. The phase relationship is related to the time interval between the two time periods of the sensing signals. Assuming that the end time of the sensing signal in time period 1 is t1, the phase at the end is p1 (0 <= p1 <= 2π), the start time of the sensing signal in time period 2 is t2, and the frequency of the sensing signal is f, then the starting phase of the sensing signal in time period 2: p2 = (p1 + (t2-t1)*f*2π) % 2π

[0285] b) Capability 2: Capability 2 is phase continuity under certain conditions. For example, phase continuity can be maintained within a window length, and the window time length T is reported.

[0286] i. That is, if the time domain interval of the two sensing signals does not exceed the window length, the two sensing signals have phase consistency.

[0287] ii. It can also be understood that if the time domain interval of the two sensing signals does not exceed the window length, for example, the time domain of sensing signal 1 is earlier, and the time domain of sensing signal 2 is later, the interval between the end time of sensing signal 1 and the start time of sensing signal 2 is t Δ , and t Δ ≤T, then the certainty of the starting phase of the sensing signal 2 and the ending phase of the sensing signal 1 meets the set phase deviation threshold. It can also be expressed as: |p2-(p1+t Δ *f*2π) % 2π| <= P Threshold

[0288] Wherein, p1 is the ending phase of the sensing signal 1, p2 is the starting phase of the sensing signal 2, f is the frequency of the sensing signal, and P Threshold is the phase deviation threshold that can guarantee the phase consistency. The threshold value can be related to the protocol definition, network configuration or product implementation. An example, P Threshold = 0. Or, P Threshold = k, k > 0.

[0289] iii. If the time domain interval of the two sensing signals exceeds the window length, for example, the time domain of sensing signal 1 is earlier, and the time domain of sensing signal 2 is later, the interval between the end time of sensing signal 1 and the start time of sensing signal 2 is t Δ , and t Δ >T, then the certainty of the starting phase of the sensing signal 2 and the ending phase of the sensing signal 1 does not meet the set phase deviation threshold. It can also be expressed as: |p2-(p1+t Δ|f2p2-f2p1|<P Threshold

[0290] where p1 is the ending phase of sensing signal 1, p2 is the starting phase of sensing signal 2, f is the frequency of sensing signal, P Threshold is the phase offset threshold that can guarantee phase consistency

[0291] iv. A little bit of out-of-the-box thinking, perhaps the Tx Node has different "modes of operation", in different modes of operation, there are different window lengths. What does different "mode of operation" mean? Perhaps it is different energy saving modes, or in different modes of operation, different hardware is used, different algorithms are deployed, under different hardware and different algorithms, the energy consumption is different, the window length that can guarantee phase consistency is also different, so the Tx Node can report multiple window lengths, respectively corresponding to different modes of operation / Tx node capability.

[0292] v. Capability 2 can also include the following form:

[0293] 1. If the 2 sensing signals sent by the Tx Node do not contain the period of the Tx Node as the receiving end (i.e. the period of the Tx Node receiving UL signals / channels). The Tx Node can maintain the phase consistency of the 2 sensing signals. If it contains the period of the Tx Node as the receiving end (i.e. the period of the Tx Node receiving UL signals / channels), the Tx Node cannot maintain the phase consistency of the 2 sensing signals.

[0294] 2. If the 2 sensing signals sent by the Tx Node contain other downlink transmission signals (such as downlink signals for communication, or other non-sensing RS, etc.) between them, and the phase of the other downlink transmission signals is continuous with the phase of the previously transmitted sensing signal, the Tx Node can maintain the phase consistency of the 2 sensing signals.

[0295] 3. If the 2 sensing signals sent by the Tx Node contain other downlink transmission signals (such as downlink signals for communication, or other non-sensing RS, etc.) between them, and the phase of the other downlink transmission signals is not continuous with the phase of the previously transmitted sensing signal, the Tx Node cannot maintain the phase consistency of the 2 sensing signals.

[0296] c) Capability 3: No phase continuity

[0297] i. There is no definite phase relationship between the multiple time-domain discontinuous sensing signals sent by the Node of this type, which cannot be used to measure the Doppler shift.

[0298] 2. The network needs to inform the Rx node about the Tx's related capability, so that the Rx can do coherent operation when receiving.

[0299] a) For example, if the Rx knows that the sensing signals from the Tx have phase continuity all the time, it can do coherent operation on any interval of sensing signals (e.g., to evaluate the Doppler shift); if the Rx knows that the sensing signals from the Tx have phase consistency within a window duration T, it can do coherent operation on the sensing signals within the window duration; if the Rx knows that the sensing signals from the Tx do not have phase consistency, it cannot do coherent operation to evaluate the Doppler shift using the sensing signals from the Tx.

[0300] b) The equivalent solution to the second point is that the network side directly configures the Rx to inform it about what kind of processing it can do when processing the sensing signals from the Tx, for example, it can do coherent operation on any interval of sensing signals (e.g., to evaluate the Doppler shift); or it can do coherent operation on the sensing signals within a window duration T; or it cannot do coherent operation to evaluate the Doppler shift using the sensing signals from the Tx.

[0301] c) A default phase consistency assumption can be agreed by the protocol or configured by the network, as follows. If the network side does not inform the Rx Node about the phase consistency capability of the Tx Node, the Rx Node defaults that the Tx Node uses one of the following default capabilities.

[0302] i. The sensing signals from the Tx have phase continuity all the time

[0303] ii. The sensing signals from the Tx have phase consistency within a window duration T, T being the default value agreed by the protocol or configured by the network

[0304] iii. The sensing signals from the Tx do not have phase consistency

[0305] 3. The network configures the Tx Node for sensing RS according to the phase consistency capability of the Tx Node.

[0306] a) For example, for a Tx Node with capability 2, the network side needs to configure the sensing frame duration to be less than or equal to the window duration T, so that all the sensing signals within a sensing frame have phase consistency, and the receiving end can use all the sensing signals within the sensing frame for coherent processing.

[0307] Frequency domain

[0308] 1. The Tx Node (BS / UE) reports to the network (SF) the capability of the Tx Node to maintain phase consistency in the frequency domain for the signals sent by the Tx Node:

[0309] a) In any RS bandwidth

[0310] b) In a configured bandwidth

[0311] i. For example, the configured bandwidth width is W1 Hz.

[0312] ii. The configured bandwidth is not only the absolute value of the frequency domain bandwidth, but also the multiple carriers of a specific band or the combination of multiple bands. For example, the Tx Node uses a common transceiver chain for band1 and band2, so the signals on band1 and band2 have phase coherence. In this case, the configured bandwidth can be understood as band1 and band2.

[0313] iii. It is also possible that the different transceiver chains used by the Tx node can be coordinated with each other, so that the signals transmitted on the bandwidth corresponding to the different transceiver chains also have phase coherence.

[0314] 2. In principle, the bandwidth of the sensing RS should be included in the phase coherence bandwidth range of the Tx Node. In this way, the receiver can use the entire frequency range of the sensing RS for target sensing. The network should configure the bandwidth of the sensing RS within the phase coherence bandwidth. If the bandwidth of the sensing RS exceeds the phase coherence bandwidth range, the receiver cannot use the sensing RS in the entire frequency domain for phase processing related operations. For phase processing related operations, the sensing RS in the frequency domain can only be divided into multiple segments for processing.

[0315] 3. The network can also inform the Rx Node of the phase coherence capability of the Tx Node in the frequency domain. A default phase coherence assumption can be configured by the protocol or the network, as follows. If the network does not inform the Rx Node of the phase coherence capability of the Tx Node, the Rx Node defaults to the following default capability of the Tx Node.

[0316] a) In any RS bandwidth

[0317] b) In a configured bandwidth. The configured bandwidth is the default value defined by the protocol. For example, the configured bandwidth = 400 MHz.
