Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This disclosure claims priority to a Chinese patent application having application number 202110076227.4, filed in China on January 20, 2021, the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the field of communications technology, and more particularly to a method and apparatus for fusing wireless communication and wireless sensing. [Background technology]

[0003] Radar-based wireless sensing technology includes two types of sensing: passive sensing and active sensing. In the passive sensing method, the sensor senses by acquiring electromagnetic waves emitted (e.g., infrared) or reflected from a target object. In the active sensing method, the sensor transmits electromagnetic waves, and after the electromagnetic waves are reflected by the target object, the sensor senses by receiving the echo. During sensing, the distance between the target object being sensed and the sensor is unknown, so the sensor needs to receive the reflected signal corresponding to the sensing signal in real time.

[0004] Currently, the fusion of wireless sensing and communication mainly adopts a method of fusion of different frequency bands, that is, wireless sensing and wireless communication operate using different operating frequency bands to reduce the influence between them. Generally, wireless sensing operates in a high frequency band, while wireless communication operates in a low frequency band. As frequency resources become scarce, the operating frequency band of wireless communication systems becomes higher and higher, and the tendency for the two to be fused and operate in the same frequency band becomes more and more prominent. However, if the two are simply arranged to operate in the same frequency band, the echo signal needs to be received in real time for radar-based wireless sensing, which increases the requirements for the transmitter and receiver of the sensor, and also affects the communication system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Thus, the appearances of "in one embodiment" or "in one embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0053] In various embodiments of the present disclosure, the order of numbers of the following processes does not imply the order of execution, and the order of execution of each process should be determined by its function and internal logic, and does not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0054] Also, the terms "system" and "network" are always used interchangeably herein.

[0055] The term "and / or" in the embodiments of the present disclosure describes a related relationship between related objects and represents that three relationships can exist, for example, A and / or B can represent three cases, such as the presence of only A, both A and B, and only B. The sign " / " generally represents that the preceding and following related objects have an "or"-like relationship.

[0056] The term "plurality" in the embodiments of this disclosure refers to two or more and other quantifiers similar thereto.

[0057] Specifically, the embodiments of the present disclosure provide a method for combining wireless communication and wireless sensing to solve the problem that communication function is affected after the sensing function is introduced into the system.

[0058] As shown in FIG. 1, an embodiment of the present disclosure provides a method for fusing wireless communication and wireless sensing, which may specifically include the following steps 101-102.

[0059] In step 101, the communication device transmits a wireless sensing signal at a target slot location associated with a switching point between signal transmission and signal reception of a wireless communication signal.

[0060] In this embodiment, the wireless sensing signal may be used to sense information such as distance, image, etc. of a target object, which may be a communication device such as a base station or a terminal, or may be other objects such as a vehicle, a building, etc. The communication device may be a base station or a terminal.

[0061] The target slot positions where the communication devices do not simultaneously transmit wireless sensing signals are different. When the communication devices are base stations, the base stations transmit wireless sensing signals at positions near a switching point between downlink transmission and uplink reception of wireless communication signals, and when the communication devices are terminals, the terminals transmit wireless sensing signals at positions near a switching point between uplink transmission and downlink reception of wireless communication signals. By transmitting the wireless sensing signals, the communication devices can determine whether a target object and other sensing parameters of the target object are present.

[0062] In step 102, an echo signal corresponding to the wireless sensing signal is received when a signal transmission slot of a wireless communication signal ends.

[0063] The communication device starts receiving an echo signal corresponding to the wireless sensing signal after the transmission slot of the wireless communication signal ends. Here, when a target object exists after the communication device transmits the wireless sensing signal, the target object reflects an echo signal, and the communication device can perform sensing processing based on the echo signal.

[0064] When the communication device is a base station, the base station starts receiving an echo signal corresponding to the wireless sensing signal after a downlink transmission slot of the wireless communication signal ends, and when the communication device is a terminal, the terminal starts receiving an echo signal corresponding to the wireless sensing signal after an uplink transmission slot of the wireless communication signal ends.

[0065] According to an embodiment of the present disclosure, a wireless sensing signal is transmitted using the transmission / reception conversion timing of a wireless communication signal, and reception of an echo signal corresponding to the wireless sensing signal is started after transmission of the wireless communication signal is completed, thereby minimizing the mutual influence when a wireless communication signal and a wireless sensing signal are multiplexed in the same frequency band, and reducing the requirements for a transceiver.

[0066] Specifically, the target slot position is: a slot position having a duration τ until an end time of a first slot, the first slot being a last signal transmission slot of the wireless communication signal; a slot position having a duration τ from a start time of a second slot, the second slot being an adjacent slot following a last signal transmission slot of the wireless communication signal; a slot position of duration τ starting before the end time of the first slot and ending after the start time of the second slot; Here, τ represents the duration of each transmission of the wireless sensing signal.

[0067] Here, when the communication device is a base station, the first slot is a downlink slot, and the second slot is an idle slot or an uplink slot after the last signal transmission slot of the wireless communication signal, and when the communication device is a terminal, the first slot is an uplink slot, and the second slot is an idle slot or a downlink slot after the last signal transmission slot of the wireless communication signal.

[0068] In this embodiment, the target slot position is a time interval, and the adjacent slot after the last signal transmission slot of the wireless communication signal may be an idle slot or a reception slot, where the adjacent slot may be an idle slot or an uplink slot when the communication device is a base station, and the adjacent slot may be an idle slot or a downlink slot when the communication device is a terminal. When the target slot position is a slot position with a duration τ that starts before the end time of a first slot and ends after the start time of a second slot, the specific time before the end time of the first slot and the specific time after the start time of the second slot for the duration τ are not limited, for example, the duration τ may start at a τ / 2 point before the end time of the first slot and end at a τ / 2 point after the start time of the second slot. That is, for the duration τ, the specific time before the end time of the first slot and the specific time after the start time of the second slot may be equal or not equal.

[0069] When the communication device is a base station, the following is an example.

[0070] The target slot position may be a slot position corresponding to a time interval of duration τ at the end of the last downlink transmission slot of the wireless communication signal in the frame structure, as shown in (a1) and (a2) in FIG. 2, where the adjacent slot after the last signal transmission slot (i.e., the last downlink slot) of the wireless communication signal in (a1) is an uplink slot, and the adjacent slot in (a2) is an idle slot.

[0071] Alternatively, the target slot position may be a slot position corresponding to a time interval of duration τ at a header portion of an adjacent slot after the last downlink transmission slot of the wireless communication signal, as shown in (b1) and (b2) in FIG. 3, where the adjacent slot after the last signal transmission slot (i.e., the last downlink slot) of the wireless communication signal in (b1) is an uplink slot, and the adjacent slot in (b2) is an idle slot.

[0072] Alternatively, the target slot position may be a slot position corresponding to a time interval spanning an end time of the first slot and a start time of the second slot and having a duration of τ, as shown in (c1) and (c2) in FIG. 4, where the adjacent slot after the last signal transmission slot (i.e., the last downlink slot) of the wireless communication signal in (c1) is an uplink slot, and the adjacent slot in (c2) is an idle slot.

[0073] When the communication device is a terminal, the following is an example.

[0074] The target slot position may be a slot position corresponding to a time interval of duration τ at the end of the last uplink transmission slot of the wireless communication signal in the frame structure, as shown in (a1) and (a2) in FIG. 5, where the adjacent slot after the last signal transmission slot (i.e., the last uplink slot) of the wireless communication signal in (a1) is a downlink slot, and the adjacent slot in (a2) is an idle slot.

[0075] Alternatively, the target slot position may be a slot position corresponding to a time interval having a duration of τ at a header portion of an adjacent slot after the last uplink transmission slot of the wireless communication signal, as shown in (b1) and (b2) in FIG. 6, where the adjacent slot after the last signal transmission slot (i.e., the last uplink slot) of the wireless communication signal in (b1) is a downlink slot, and the adjacent slot in (b2) is an idle slot.

[0076] Alternatively, the target slot position may be a slot position corresponding to a time interval spanning an end time of the first slot and a start time of the second slot and having a duration of τ, as shown in (c1) and (c2) in FIG. 7, where the adjacent slot after the last signal transmission slot (i.e., the last uplink slot) of the wireless communication signal in (c1) is a downlink slot, and the adjacent slot in (c2) is an idle slot.

[0077] According to Figures 3, 4, 6 and 7, if the target slot position is a slot position with a duration of τ after the start time of the second slot, or if the target slot position is a slot position with a duration of τ that starts before the end time of the first slot and ends after the start time of the second slot, when the communication device transmits the wireless sensing signal, the communication device needs to perform transmission and reception operations simultaneously, that is, the communication device has the function of simultaneously transmitting and receiving in the same frequency band. Specifically, the communication device can adopt a full duplex method or a multi-transmit receive point (TRP) cooperative sensing method.

[0078] Further, the wireless sensing signal occupies the whole or a part of the operating frequency band corresponding to the target slot position. Here, when the wireless sensing signal occupies a part of the operating frequency band corresponding to the target slot position, the wireless sensing signal may be configured to transmit or not transmit a wireless communication signal in the remaining frequency band of the target slot. When the wireless sensing signal occupies a part of the operating frequency band corresponding to the target slot position and transmits a wireless communication signal in a frequency band other than the part of the operating frequency band, the wireless sensing signal and the wireless communication signal can be multiplexed and operated using the same time-frequency division, thereby making it possible to maximize the use of frequency resources.

[0079] Specifically, transmitting a wireless sensing signal at a target slot position related to a switching point between signal transmission and signal reception of the wireless communication signal includes one of the following (1) to (3).

[0080] (1) Transmitting the wireless sensing signal in the entire operating frequency band corresponding to the target slot position. In this embodiment, when the communication device transmits a wireless sensing signal, it can only transmit the wireless sensing signal in an operating frequency band corresponding to the target slot position, and the wireless sensing signal occupies the entire frequency band as shown in Fig. 8a, where if the communication device is a base station, the slot in Fig. 8a is a downlink slot, and if the communication device is a terminal, the slot in Fig. 8a is an uplink slot, and the shaded part in Fig. 8a is the frequency band for transmitting the wireless sensing signal. In this case, the wireless communication signal can be transmitted in a frequency band before the operating frequency band shown in Fig. 8a.

[0081] (2) Transmitting the wireless sensing signal in a portion of an operating frequency band corresponding to the target slot position. In this embodiment, when the communication device transmits a wireless sensing signal, it can transmit the wireless sensing signal in a part of the frequency band of the operating frequency band corresponding to the target slot position, and the wireless sensing signal occupies a part of the frequency band as shown in Fig. 8b, where if the communication device is a base station, the slot in Fig. 8b is a downlink slot, and if the communication device is a terminal, the slot in Fig. 8b is an uplink slot, and the shaded part in Fig. 8b is the frequency band for transmitting the wireless sensing signal. In Fig. 8b, the wireless sensing signal and the wireless communication signal are not frequency division multiplexed.

[0082] (3) Transmitting the wireless sensing signal and the wireless communication signal in an operating frequency band corresponding to the target slot position using a frequency division multiplexing scheme. In this embodiment, when transmitting a wireless sensing signal, the communication device can transmit the wireless sensing signal in a part of the frequency band of the operating frequency band corresponding to the target slot position, and transmit the wireless communication signal in another part of the frequency band of the operating frequency band, and as shown in Fig. 8c, the wireless sensing signal occupies a part of the frequency band, and the wireless communication signal occupies the remaining part of the frequency band, where if the communication device is a base station, the slot in Fig. 8c is a downlink slot, and if the communication device is a terminal, the slot in Fig. 8c is an uplink slot, the shaded part in Fig. 8c is the frequency band part for transmitting the wireless sensing signal, and the remaining blank part of the operating frequency band is the frequency band part for transmitting the wireless communication signal. In Fig. 8c, the wireless sensing signal and the wireless communication signal are frequency division multiplexed.

[0083] According to this embodiment, wireless sensing and wireless communication are integrated and operate using the same operating frequency band, thereby making maximum use of frequency resources.

[0084] Further, transmitting a wireless sensing signal at a target slot position associated with a switching point between signal transmission and signal reception of the wireless communication signal includes: During the sensing probe period, it includes transmitting the wireless sensing signal N times with the target period, where N×T1 < T, T1 represents the target period and is an integer multiple of the subframe time for transmitting the wireless communication signal, and T represents the sensing probe period.

[0085] In this embodiment, for the wireless sensing signal transmitted N times with the target period within the sensing probe period, it may be the same wireless sensing signal or different sensing signals. Thereby, blurring removal and / or scanning of the environment can be realized.

[0086] Specifically, when the communication device is a base station, the frame formats of the wireless sensing signal and the wireless communication signal can be as shown in FIG. 9. The wireless sensing signal can be generated by adopting signal generation methods widely used in radar systems, such as linear frequency modulation and phase shift pulse modulation. Within the sensing probe period, the wireless sensing signal is transmitted N times with the target period T1, and the duration of each transmission is τ, and N×T1 < T. By setting two periods (sensing probe period and target period) for transmitting the wireless sensing signal, blurring can be removed, and the sensing accuracy can be improved by transmitting the wireless sensing signal multiple times. And when one period is set, the situation that an echo signal cannot be received within the period of transmitting the wireless sensing signal and the transmission position of the echo signal cannot be known when the echo signal is received in the next period can be avoided.

[0087] As an optional embodiment, when the communication device operates in full-duplex mode, the time for receiving the echo signal corresponding to the wireless sensing signal is Tr1 = T1 - τ, where Tr1 represents the time for receiving the echo signal, τ represents the duration of each transmission of the wireless sensing signal, and the conversion time between signal transmission and signal reception of the wireless communication signal is zero.

[0088] In another alternative embodiment, when the communication device operates in a Time Division Duplex (TDD) mode, the time to receive an echo signal corresponding to the wireless sensing signal is: Tr2=T1-τ-Td1-T0, Here, Tr2 represents the time for receiving the echo signal, τ represents the duration for transmitting the wireless sensing signal each time, Td1 represents the time of the transmission slot of the wireless communication signal, and T0 represents the conversion time between signal transmission and signal reception of the wireless communication signal.

[0089] Here, the time window for receiving the echo signal corresponding to the wireless sensing signal can be self-determined by the sensing receiver of the communication device based on the sensing probe range. The sensing receiver of the communication device detects the echo signal within the time for receiving the echo signal, and determines the arrival time, phase, intensity, etc. of the echo signal through a detection algorithm such as sliding filtering of the local wireless sensing signal and the echo signal, thereby detecting information such as target position, attitude, image, etc. of the target object.

[0090] Below, using specific embodiments, the implementation process of the method for combining wireless communication and wireless sensing when the communication device is a base station, and the implementation process of the method for combining wireless communication and wireless sensing when the communication device is a terminal will be described respectively.

[0091] As an example 1, a base station transmits a wireless sensing signal.

[0092] The base station transmits a sensing signal near a switching point from its downlink transmission to its uplink reception, and when its downlink transmission ends, begins receiving for an echo signal corresponding to the wireless sensing signal.

[0093] Here, "near the switch point from downlink transmission to uplink reception" means being at the end of the last slot of downlink transmission in the frame structure (as shown in Figure 2), being at the header of the slot (including two cases, an idle slot or an uplink slot) following the last slot of downlink transmission (as shown in Figure 3), or straddling the end of the last slot and the header of the slot following (as shown in Figure 4).

[0094] Specifically, the phrase "when downlink transmission is completed" refers to "after the downlink slot corresponding to the transmission of wireless communication signals is completed". For the two types of wireless sensing signal transmission methods, the method at the end of the last slot of downlink transmission and the method spanning the end of the last slot and the header of the next slot, the base station needs to perform transmission and reception operations simultaneously, that is, the base station has the function of simultaneously transmitting and receiving in the same frequency band. Specifically, the base station can adopt a full duplex method or a multi-TRP cooperative sensing method.

[0095] As shown in Figures 8a to 8c, when transmitting a wireless sensing signal, only the wireless sensing signal can be transmitted in the operating frequency band corresponding to the target slot position, occupying all or a part of the operating frequency band, or the wireless communication signal and the wireless sensing signal can be transmitted simultaneously, and both of them adopt a frequency division multiplexing scheme.

[0096] As an example 2, the terminal transmits a wireless sensing signal.

[0097] The terminal transmits a wireless sensing signal near a switching point from its uplink transmission to its downlink reception, and when its uplink transmission ends, starts receiving for an echo signal corresponding to the wireless sensing signal.

[0098] Here, "near the switch point from uplink transmission to downlink reception" means being at the end of the last slot of uplink transmission in the frame structure (as shown in FIG. 5), being at the header of the slot (including two cases of an idle slot or a downlink slot) following the last slot of uplink transmission (as shown in FIG. 6), or straddling the end of the last slot and the header of the slot following (as shown in FIG. 7).

[0099] Specifically, the phrase "when the downlink transmission is completed" means "after the uplink slot corresponding to the transmission of the wireless communication signal is completed." If the wireless sensing signal is transmitted in one slot after the last slot of the uplink transmission, the terminal needs to perform the transmission and reception operations simultaneously, that is, the terminal has the function of simultaneously transmitting and receiving in the same frequency band.

[0100] As shown in Figures 8a to 8c, when transmitting a wireless sensing signal, only the wireless sensing signal can be transmitted in the operating frequency band corresponding to the target slot position, occupying all or a part of the operating frequency band, or the wireless communication signal and the wireless sensing signal can be transmitted simultaneously, and both of them adopt a frequency division multiplexing scheme.

[0101] Optionally, prior to transmitting the wireless sensing signal at a target slot position associated with a switch point between signal transmission and signal reception of the wireless communication signal, the method may further include generating a wireless communication signal. Prior to transmitting the wireless sensing signal at a target slot position associated with a switch point between signal transmission and signal reception of the wireless communication signal, the method may further include generating a wireless communication signal.

[0102] As an alternative embodiment, the method may further include generating a first transmission control signal for transmitting the wireless sensing signal, the first transmission control signal being used to control a first transmission channel to transmit the wireless sensing signal, and generating a first reception control signal for receiving an echo signal corresponding to the wireless sensing signal when a signal transmission slot of the wireless communication signal ends, the first reception control signal being used to control a first reception channel to receive the echo signal. Specifically, transmitting the wireless sensing signal at a target slot position related to a switching point of signal transmission and signal reception of the wireless communication signal may include transmitting the wireless sensing signal through the first transmission channel at a target slot position related to a switching point of signal transmission and signal reception of the wireless communication signal based on the first transmission control signal. Receiving the echo signal corresponding to the wireless sensing signal when a signal transmission slot of the wireless communication signal ends may include receiving the echo signal corresponding to the wireless sensing signal through the first reception channel based on the first reception control signal when the first reception channel is turned on.

[0103] The embodiment is applied to a scene in which the communication device transmits a wireless sensing signal at a slot position where the duration until the end time of the first slot is τ. The communication device transmits the wireless communication signal and the wireless sensing signal through the first transmission channel, and when the transmission slot (downlink slot or uplink slot) of the wireless communication signal ends, the communication device can turn off the first transmission channel and turn on the first reception channel regardless of whether the slot after the transmission slot is a reception slot (uplink slot or downlink slot) or an idle slot. After transmitting the wireless communication signal and the wireless sensing signal, the communication device performs conversion between the first transmission channel and the first reception channel, and receives an echo signal corresponding to the wireless sensing signal when turning on the first reception channel. Specifically, the wireless sensing signal is located at the end of the last transmission slot of the wireless communication signal, and may occupy the entire operating frequency band or only a part of the operating frequency band, or may be frequency division multiplexed in the same operating frequency band as the wireless communication signal.

[0104] In order to support that the wireless sensing signal can be transmitted in a slot subsequent to the last transmission slot of the wireless communication signal, as another optional embodiment, the method may further include: generating a second transmission control signal for transmitting the wireless communication signal, wherein the second transmission control signal is used to control a second transmission channel to transmit the wireless communication signal; generating a second reception control signal for receiving the wireless communication signal after transmitting the wireless communication signal, wherein the second reception control signal is used to control the second reception channel to receive the wireless communication signal; generating a third transmission control signal for transmitting the wireless sensing signal before transmitting the wireless sensing signal, wherein the third transmission control signal is used to control the third transmission channel to transmit the wireless sensing signal; and generating a third reception control signal for receiving an echo signal corresponding to the wireless sensing signal when the transmission of the wireless sensing signal is completed and the signal transmission slot of the wireless communication signal ends, wherein the third reception control signal is used to control the third reception channel to receive the echo signal.

[0105] The communication device transmits a wireless communication signal through the second transmission channel based on the second transmission control signal when the second transmission channel is turned on, and receives the wireless communication signal through the second reception channel based on the second reception control signal when the second reception channel is turned on. Specifically, transmitting a wireless sensing signal at a target slot position related to a switching point between signal transmission and signal reception of the wireless communication signal may include transmitting the wireless sensing signal through the third transmission channel at a target slot position related to a switching point between signal transmission and signal reception of the wireless communication signal based on the third transmission control signal when the third transmission channel is turned on, and receiving an echo signal corresponding to the wireless sensing signal when a signal transmission slot of the wireless communication signal ends may include receiving an echo signal corresponding to the wireless sensing signal through the third reception channel based on the third reception control signal when the third reception channel is turned on.

[0106] In this embodiment, the communication device turns on the second transmission channel before transmitting the wireless sensing signal, and when the second transmission channel is turned on, transmits the wireless communication signal via the second transmission channel, thereby performing conversion between the second transmission channel and a second receiving channel, and when the second receiving channel is turned on, can receive the wireless communication signal via the second receiving channel.

[0107] The communication device may turn on the third transmission channel before transmitting the wireless sensing signal, and when the third transmission channel is turned on, transmit the wireless sensing signal via the third transmission channel, and when the transmission of the wireless sensing signal is completed, turn off the third transmission channel (or may not be turned off). When the transmission slot (downlink slot or uplink slot) of the wireless communication signal is completed, the communication device may turn on the third reception channel, receive an echo signal corresponding to the wireless sensing signal via the third reception channel, and when the reception of the echo signal is completed, turn off the third reception channel (or may not be turned off). Specifically, the wireless sensing signal may be located at the end of the last transmission slot of the wireless communication signal, or at the header of the slot following the last transmission slot of the wireless communication signal, or may straddle the end of the last transmission slot of the wireless communication signal and the header of the following slot, and may occupy the entire operating frequency band or only a part of the operating frequency band, or may be frequency division multiplexed in the same operating frequency band as the wireless communication signal.

[0108] According to an embodiment of the present disclosure, a wireless sensing signal is transmitted using the transmission / reception conversion timing of a wireless communication signal, and reception of an echo signal corresponding to the wireless sensing signal is started after transmission of the wireless communication signal is completed, thereby minimizing the mutual influence when a wireless communication signal and a wireless sensing signal are multiplexed in the same frequency band, and reducing the requirements for a transceiver.

[0109] The technical solutions in the embodiments of the present disclosure may be applied to various systems, particularly 5G systems. For example, the applied systems may be global system of mobile coMunication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) general packet radio service (GPRS) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, long term evolution advanced (LTE-A) systems, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G New Radio (NR) (New Radio, NR) systems, etc. All of these systems include terminal equipment and network equipment.
