Apparently, the described embodiments are only some rather than all of the embodiments of this application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of this application shall fall within the protection scope of this application.
In the specification and claims of this application, the terms such as “first” and “second” are intended to distinguish between similar objects but do not necessarily indicate a specific order or sequence. It should be understood that the data used in this way is interchangeable in appropriate circumstances so that the embodiments of this application can be implemented in other orders than the order illustrated or described herein, and “first” and “second” are usually for distinguishing same-type objects but not limiting the number of objects, for example, there may be one or more first objects. In addition, “and/or” in this specification and claims indicates at least one of connected objects, and the symbol “/” generally indicates that the associated objects are in an “or” relationship.
It should be noted that techniques described in the embodiments of this application are not limited to a Long Term Evolution (LTE) or LTE-Advanced (LTE-A) system, and may also be applied to various wireless communication systems, for example, Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms “system” and “network” in the embodiments of this application are usually used interchangeably. Techniques described herein may be used in the aforementioned systems and radio technologies, and may also be used in other systems and radio technologies. In the following descriptions, a New Radio (NR) system is described for an illustration purpose, and NR terms are used in most of the following descriptions, although these technologies may also be applied to other applications than an NR system application, for example, the 6G communication system.
To better understand the technical solutions in the embodiments of this application, the following content is first described.
Future mobile communication systems, such as Beyond 5th Generation (B5G) systems or 6G systems, will not only have communication capabilities, but also have sensing capabilities.
For sensing capability, one or more devices with sensing capability can transmit and receive radio signals to sense information such as orientation, distance, and speed of a target object, or to perform detection, tracking, identification, and imaging of a target object, event, or environment. In the future, with the deployment of small cell base stations with high frequency band and large bandwidth such as millimeter wave and terahertz in 6G networks, the sensing resolution will be significantly improved compared with centimeter wave, thus enabling 6G networks to provide more detailed sensing services. Typical sensing functions and application scenarios are shown in Table 1.
The integration of communication and sensing is to implement integrated design of communication and sensing functions through spectrum sharing and hardware sharing in a same system. While transmitting information, the system may sense information such as azimuth, distance, and speed, to detect, track and identify a target device or event. The communication system and the sensing system complement each other, thus improving overall performance and bringing better service experience.
The integration of communication and radar is a typical application of the integration of communication and sensing (fusion of communication and sensing). In the past, the radar system and communication system were strictly distinguished because of different research objects and focus, and the two systems were studied independently in most scenarios. Actually, the radar and communication systems are also typical ways of information transmission, acquisition, processing, and exchange, and there are many similarities in working principle, system architecture, and frequency band. The integrated design of communication and radar has great feasibility, which is mainly reflected in the following aspects: firstly, both the communication system and the sensing system are based on the electromagnetic wave theory, and implement information acquisition and transmission through transmission and reception of electromagnetic wave; secondly, both the communication system and the sensing system have structures such as an antenna, a transmitter, a receiver, and a signal processor, greatly overlapping in hardware resources. With the development of technologies, the two increasingly overlap in the working frequency band. In addition, there are similarities in key technologies such as signal modulation, reception detection, and waveform design. The integration of communication and radar systems may bring many advantages, such as saving cost, reducing size, reducing power consumption, improving spectrum efficiency, and reducing mutual interference, thus improving overall performance of the system.
According to the difference between a transmitting node and a receiving node of the sensing signal, there may be the following six types of sensing links, as shown in
1) Echo sensing for a base station. In this manner, the base station sends a sensing signal and obtains a sensing result by receiving echo of the sensing signal.
2) Air interface sensing between base stations. In this manner, a base station 2 receives a sensing signal sent by a base station 1 and obtains a sensing result.
3) Uplink air interface sensing. In this manner, a base station receives a sensing signal sent by User Equipment (UE) and obtains a sensing result.
4) Downlink air interface sensing. In this manner, the UE receives a sensing signal sent by the base station and obtains a sensing result.
5) Echo sensing for a terminal. In this manner, the UE sends a sensing signal and obtains a sensing result by receiving echo of the sensing signal.
6) Sidelink sensing between terminals. For example, UE 2 receives a sensing signal sent by UE 1 and obtains a sensing result.
The following describes in detail a sensing signal processing method provided in the embodiments of this application by using some embodiments and application scenarios thereof with reference to the accompanying drawings.
First, the terms involved in the embodiments of this application are explained and described:
The first requirement includes a fuzzification requirement related to wireless sensing, a sensing privacy requirement, or a sensing error requirement. For example:
a) Fuzzification requirement/privacy requirement for a position of a sensed sensing object, such as a position of the sensing object plus a random deviation in a range of −1 m to 1 m or a random angle error of −5 degrees to +5 degrees for angle information.
b) Adding a deviation to trajectory information. Trajectory consists of multiple positions at different times. To keep trajectory of fuzzification processing continuous, position errors at different times need to be consistent.
c) Sensing characteristics of a sensing object, such as a human body, for example, scanning body contour characteristics of a person through radio signals, merely for the purpose of virtual fitting, instead of obtaining more detailed information for other purposes. In this case, the first requirement may be a minimum 3D sensing resolution, for example, 5 cm×5 cm×5 cm.
d) Imaging: for example, imaging results of some sensing objects feature privacy.
For example, for face information, 2D information of face may be obtained by radio signal scanning. In this case, the first requirement may be a minimum 2D sensing resolution, such as 2 cm×2 cm. In this case, the first requirement is not to display a sensing result of human face, but only to display a sensing result of other human parts.
e) Map construction/3D environment reconstruction: Map information or environment reconstruction information of some sensitive areas or sensitive buildings belongs to private information. In this case, the first requirement includes characteristic information of the sensitive areas or sensitive buildings, such as location information, and a minimum resolution for map construction of the sensitive areas or sensitive buildings (for example, the minimum resolution of map construction of the sensitive areas or sensitive buildings is 10 m×10 m×10 m, and other non-sensitive areas are 1 m×1 m×1 m).
f) Radar: For example, results of ranging, speed measurement, and angle measurement by radar, and sensing results for some sensing objects may be private. In this case, the first requirement is a resolution requirement for ranging, speed measurement, and angle measurement of some sensing objects, such as a minimum velocity resolution of 1 meter per second, a minimum distance resolution of 10 meters, and a minimum angle resolution of 10 degrees. For another example, the first requirement in this case is to add one absolute error to the result of ranging, speed measurement, and angle measurement, or add a relative error such as a 10% error to the result of ranging, speed measurement and angle measurement.
g) Minimum granularity requirement or quantification requirement of human heart rate and respiratory rate obtained through wireless sensing, for example, the granularity of the minimum heartbeat frequency is 5 times/minute, and the granularity of minimum respiratory frequency is 2 times/minute.
h) Health: Information such as blood oxygen, blood pressure, or sleep quality belongs to personal private information. The first requirement in this case is, for example, the granularity of minimum blood oxygen or blood pressure.

For another example, for a sensing signal spontaneously sent and received, dmax represents a maximum distance from a sensing signal receive point to a signal transmit point. In some cases, a Cyclic Prefix (CP) of OFDM signals can act as a minimum guard period; where c represents the speed of light.
d) Bandwidth: this parameter is inversely proportional to a distance resolution and can be obtained by c/2/delta_d, where delta_d represents a distance resolution (belonging to the sensing requirement).
e) Burst duration: this parameter is inversely proportional to a rate resolution (belonging to the sensing requirement), and this parameter is a time span of the sensing signal, mainly for calculating Doppler frequency shift; this parameter can be calculated by c/2/delta_v/fc, where delta_v represents a velocity resolution, and fc represents a carrier frequency of the signal or a central frequency of the signal.
f) Time domain interval, where this parameter can be calculated by c/2/fc/v_range; v_range represents a maximum rate minus a minimum speed (belonging to the sensing requirement), and this parameter is a time interval between two adjacent sensing signals.
g) Power information of a transmitted signal includes transmission power, peak power, average power, total power, power spectral density, Effective Isotropic Radiated Power (EIRP), power of each port, and the like. For example, a value of the transmission power is taken every 2 dBm from −20 dBm to 23 dBm; and a value of the transmit signal power or EIRP, for example, is taken every 2 dBm from −20 dBm to 23 dBm.
