Description

Technical Field

[0001] This disclosure relates generally to wireless sensing, and in particular to sensing measurement. Background Technology

[0002] From first-generation analog communication to the fifth-generation mobile communication system that enables the Internet of Things, mobile communication has not only profoundly changed people's lifestyles but has also become a new engine for accelerating the digitalization of society. With the continuous emergence of new services and demands, mobile communication systems can provide increasingly powerful communication capabilities. Among these, wireless sensing is an important potential direction. Compared to two separate systems, the integrated design of communication and sensing can reduce costs, lower power consumption, and optimize resource utilization. Integrated Sensing and Communication (ISAC) achieves a unified design of communication and sensing control functions through joint signal design and / or hardware sharing. Sensing in ISAC can be understood as wireless sensing technology based on mobile communication systems. Mobile communication systems can transmit wireless signals and analyze the reflected or scattered waves of these signals to obtain corresponding sensing measurement data. Summary of the Invention

[0024] Some arrangements involve sensing control functions and sensing measurement units. In some arrangements, the sensing control function (or sensing function) can be a new logical function of the core network (CN) (e.g., software, firmware, application, operation, or procedure), or an enhancement or addition to an existing logical function, such as the CN's Location Management Function (LMF). In some examples, the sensing control function can be a functional module of the radio access network (RAN) (e.g., software, firmware, application, operation, or procedure executed thereon). That is, in some arrangements, the sensing control function can be implemented at a base station (BS) or user equipment (UE). In some arrangements, the sensing measurement unit can be a BS, UE, or another suitable wireless communication device, wireless communication node, etc.

[0025] Figure 1A This is a flowchart illustrating an example method 100a for configuring sensing according to various arrangements. Method 100a can be performed by a sensing measurement unit 102 and a sensing control function 104. In some arrangements, the sensing measurement unit 102 includes a first UE or a first BS. In some arrangements, the sensing control function includes the functions of a second wireless communication device, a second BS, or a CN.

[0026] At 110, the sensing measurement unit 102 sends a request to the sensing control function 104 to perform sensing measurements. This request includes multiple sets of sensing parameters defining multiple sensing regions for a sensing reference signal. Each set of sensing parameters defines one of the multiple sensing regions. At 120, the sensing control function 104 receives the request from the sensing measurement unit 102.

[0027] At 130, the perception control function 104 sends a response to the perception measurement unit 102, which is received by the perception measurement module 102 at 140. At 150, the perception measurement unit 102 transmits perception reference signals in multiple perception areas. For example, the perception measurement unit 102 may be a perception transmitter that transmits perception reference signals to a perception receiver, which may be a perception measurement unit such as the perception measurement unit 102 (e.g., a BS, UE, or another network node).

[0028] Figure 1B This is a flowchart illustrating an example method 100b for configuring sensing according to various arrangements. Depending on the arrangement, method 100b can be executed by a first sensing measurement unit 106.

[0029] At 160, the first sensing measurement unit 106 receives a request from a sensing control function (e.g., sensing control function 104) or a second sensing measurement unit (e.g., sensing measurement unit 102) to perform a sensing measurement. This request includes multiple sets of sensing parameters defining multiple sensing regions. Each set of sensing parameters defines one of the multiple sensing regions. At 170, the first sensing measurement unit 106 measures one or more sensing reference signals based on the multiple sensing regions.

[0030] In some arrangements, the first sensing measurement unit 106 reports measurement results associated with each of a plurality of sensing regions or within each of a plurality of sensing regions. In some arrangements, the first sensing measurement unit 106 does not report measurement results for regions outside the plurality of sensing regions. In some arrangements, multiple sets of sensing parameters of the sensing measurements indicate multiple sensing reference signals. In some arrangements, the first sensing measurement unit reports results for each of the multiple sensing reference signals. In some arrangements, the first sensing measurement unit 106 does not report results for sensing reference signals different from the plurality of sensing reference signals.

[0031] In some arrangements, for each of the multiple sensing regions, each of the multiple sets of sensing parameters includes at least one of the following: the signal power of the sensing reference signal, the sensing distance of the sensing reference signal, the sensing direction of the sensing reference signal, the sensing time of the sensing reference signal, the sensing phase of the sensing reference signal, or the Doppler of the sensing reference signal.

[0032] In some arrangements, signal power includes a signal power range, wherein the signal power range is defined by at least one of the following: a minimum threshold of the signal power range, a maximum threshold of the signal power range, or a combination of the minimum threshold and the maximum threshold of the signal power range. Sensing distance includes a sensing distance range, wherein the sensing distance range is defined by at least one of the following: a minimum threshold of the sensing distance range, a maximum threshold of the sensing distance range, or a combination of the minimum threshold and the maximum threshold of the sensing distance range. Sensing direction includes a sensing direction range, wherein the sensing direction range is determined based on the orientation or capability of the antenna panel of the sensing measurement unit. Sensing time is the delay from the second sensing measurement unit to the first sensing measurement unit, and sensing time includes a sensing time range, wherein the sensing time range is defined by at least one of the following: a minimum time of the sensing time range, a maximum threshold of the sensing time range, or a combination of the minimum time and the maximum threshold of the sensing time range. Sensing phase includes a sensing phase range. The sensing phase range is defined by at least one of the following: a minimum phase of the sensing phase range, a maximum threshold of the sensing phase range, or a combination of the minimum phase and the maximum threshold of the sensing phase range. Doppler includes the perceived Doppler range, wherein the perceived Doppler range is defined by at least one of the following: the minimum Doppler of the perceived Doppler range, the maximum threshold of the perceived Doppler range, or a combination of the minimum Doppler of the perceived Doppler range and the maximum Doppler of the perceived Doppler range.

[0033] In some arrangements, each of the multiple sets of sensing parameters includes a priority for each of the multiple sensing regions. In some arrangements, each of the multiple sets of sensing parameters includes the bandwidth and period of the sensing reference signal for each of the multiple sensing regions.

[0034] In some arrangements, the first sensing measurement unit 106 receives a reflected or scattered signal corresponding to a sensing reference signal and measures the reflected or scattered signal.

[0035] In some arrangements, the first sensing measurement unit 106 receives from the sensing control function a measurement configuration for measuring the reflected or scattered signal corresponding to the sensing reference signal.

[0036] In some arrangements, the measurement configuration includes at least one detection threshold. The detection threshold defines a power threshold for a reflected or scattered signal corresponding to the presence of at least one object. In some arrangements, the first sensing measurement unit 106 reports the sensing measurement results based on the detection threshold.

[0037] Figure 1CThis is a flowchart illustrating an example method 100c for configuring sensing according to various arrangements. Depending on the arrangement, method 100c can be executed by a sensing control function 104. At 180, the sensing control function 104 receives a report from a second sensing measurement unit for performing sensing measurements. This report includes multiple sets of sensing parameters defining multiple sensing regions for a sensing reference signal. At 190, the sensing control function 104 sends a request to a first sensing measurement unit 106. This request includes multiple sets of sensing parameters defining multiple sensing regions for the sensing measurement.

[0038] In some arrangements, this report is used for reference signal transmission. The report includes multiple sets of sensing parameters defining multiple sensing regions. Each set of sensing parameters defines one of the multiple sensing regions used for sensing reference signal transmission. In some arrangements, the multiple sets of sensing parameters for sensing measurements are a subset of the multiple sets of sensing parameters for sensing the reference signal.

[0039] In some examples, the sensing measurement unit sends a request to the sensing control function. This request includes at least one of the following: signal power (e.g., signal power range), sensing distance (e.g., sensing distance range), sensing direction (e.g., sensing direction range), or sensing time (e.g., sensing time range). In some examples, a threshold corresponding to the received power of the sensing reference signal to be measured is used to indicate the range of the signal power. In some examples, the sensing distance range can be used to indicate the distance range of the sensing reference signal to be measured. In some examples, the sensing direction range is used to indicate the directional range of the sensing reference signal to be measured. In some examples, the sensing time range is used to indicate the expected time range for measuring the sensing reference signal.

[0040] In some examples, a minimum threshold can be used to indicate the signal power range, indicating that the sensing reference signal to be detected exceeds this minimum threshold. In other words, the signal power range is a range with a lower limit, which is the minimum threshold or higher. In some arrangements, the minimum threshold indicates that the sensing measurement unit is expected to detect sensing reference signals exceeding the minimum threshold. For example, in response to determining that the power value of a detected signal is less than the minimum threshold, the sensing measurement unit ignores the detected signal and / or does not report it. In some examples, a maximum threshold can be used to indicate the signal power range, indicating that the sensing reference signal to be detected does not exceed this minimum threshold. In some examples, the signal power range can be defined by a minimum threshold (or value), a maximum threshold (or value), or a combination of minimum and maximum values. That is, in some arrangements, the sensing measurement unit expects the signal power of the detected signal to be between the minimum threshold and the maximum threshold. Otherwise, the sensing measurement unit will not report sensing reference signals whose signal power is not between the minimum and maximum thresholds.

[0041] In some examples, distance units such as meters, kilometers, and miles are used to indicate the sensing distance range. A minimum distance can be used to indicate that the sensing reference signal to be detected is not less than the minimum distance. In the example, a sensing distance range defined by a minimum distance of 200m indicates that the sensing measurement unit expects to detect sensing reference signals at a distance of not less than 200m. The sensing measurement unit ignores or does not report signals at distances greater than 200m. In some examples, a maximum distance can be used to indicate that the sensing reference signal to be detected is less than the maximum distance. The sensing distance range can be defined by a minimum distance (e.g., 100 meters, 200 meters, etc.), a maximum distance (e.g., 500 meters), or a combination of minimum and maximum distances. That is, in some arrangements, the sensing measurement unit expects to detect signals at sensing distances between a minimum threshold and a maximum threshold. Otherwise, the sensing measurement unit will not report sensing reference signals at sensing distances not between the minimum and maximum thresholds.

[0042] In some examples, to indicate the sensing direction range, the sensing measurement unit may report the sensing direction range based on the orientation or capability of the sensing measurement unit's antenna panel. The sensing direction range may correspond to a direction, a range of directions, an angle, or a range of angles. The sensing measurement unit indicates the sensing direction range.

[0043] In some examples, the sensing time range is the expected delay range of the measured signal. Delay is defined as the delay of the air interface, i.e., the delay from the sensing transmitter sending the sensing reference signal to the sensing receiver receiving the sensing reference information. Sensing time is measured in units of time, such as seconds, milliseconds, nanoseconds, etc. The sensing time range can be defined by a minimum time (e.g., 20 μs), which indicates the minimum delay of the signal that the sensing measurement unit expects to detect. The sensing time range can also be defined by a maximum time (e.g., 100 μs), which indicates the maximum delay of the signal that the sensing measurement unit expects to detect. The sensing time range can be defined by the minimum time, the maximum time, or a combination of the minimum and maximum times. That is, in some arrangements, the sensing measurement unit expects to detect a sensing reference signal whose sensing time (e.g., delay) is between the minimum and maximum times. Otherwise, the sensing measurement unit does not report a sensing reference signal whose sensing time is not between the minimum and maximum times.

[0044] In some arrangements, the signal power of the sensing reference signal, the sensing distance of the sensing reference signal, the sensing direction of the sensing reference signal, and the sensing time of the sensing reference information can be collectively referred to as sensing parameters. A request message may carry multiple values ​​of the sensing parameters, which together indicate a sensing area. In some arrangements, for each of multiple sensing areas, each set of multiple sensing parameters includes at least one of the following: the signal power of the sensing reference signal, the sensing distance of the sensing reference signal, the sensing direction of the sensing reference signal, the sensing time of the sensing reference signal, the sensing phase of the sensing reference signal, or the Doppler effect of the sensing reference signal.

[0045] In some arrangements, signal power includes a signal power range, wherein the signal power range is defined by at least one of the following: a minimum threshold of the signal power range, a maximum threshold of the signal power range, or a combination of the minimum threshold and the maximum threshold of the signal power range. Sensing distance includes a sensing distance range, wherein the sensing distance range is defined by at least one of the following: a minimum threshold of the sensing distance range, a maximum threshold of the sensing distance range, or a combination of the minimum threshold and the maximum threshold of the sensing distance range. Sensing direction includes a sensing direction range, wherein the sensing direction range is determined based on the orientation or capability of the antenna panel of the sensing measurement unit. Sensing time is the delay from the second sensing measurement unit to the first sensing measurement unit, and sensing time includes a sensing time range, wherein the sensing time range is defined by at least one of the following: a minimum time of the sensing time range, a maximum threshold of the sensing time range, or a combination of the minimum time and the maximum threshold of the sensing time range. Sensing phase includes a sensing phase range. The sensing phase range is defined by at least one of the following: a minimum phase of the sensing phase range, a maximum threshold of the sensing phase range, or a combination of the minimum phase and the maximum threshold of the sensing phase range. Doppler includes the perceived Doppler range, wherein the perceived Doppler range is defined by at least one of the following: the minimum Doppler of the perceived Doppler range, the maximum threshold of the perceived Doppler range, or a combination of the minimum Doppler of the perceived Doppler range and the maximum Doppler of the perceived Doppler range.

[0046] Figure 2 This is a schematic diagram illustrating a sensing region 200 according to various arrangements. For example, the sensing region 200 is defined by sensing parameters carried in a request message, including a sensing angle range 210, a defined sensing direction, and a distance range 220 relative to the sensing measurement unit 205. In some examples, the sensing angle range 210 is [0°, 30°], and the sensing distance range 220 is [300m, 400m]. The sensing angle range 210 and the sensing distance range 220 together identify the sensing region 200 relative to the sensing measurement unit 205.

[0047] In some configurations, the sensing measurement unit has the ability to measure multiple sensing areas. Figure 3 This is a schematic diagram illustrating a sensing measurement unit 305 configured to measure sensing regions 310, 320, and 330 according to various arrangements. In some examples, the sensing measurement unit 305 may be a BS or UE, or another suitable device having the capability or requirement to detect multiple sensing regions 310, 320, and 330. Each of the sensing regions 310, 320, and 330 may be defined by a set of sensing parameters in the manner described herein.

[0048] In some examples, the sensing measurement unit 305 sends a request to the sensing control function. The request message includes a list of sensing regions 310, 320, and 330, in which the sensing measurement unit 305 expects or is configured to detect sensing reference signals.

[0049] In some arrangements, the methods for determining or identifying each sensing area can be the same or different. For example, sensing area 310 can be determined by a sensing distance range, sensing area 310 can be determined by a sensing distance range and a sensing angle range, while sensing area 330 can be defined by location coordinates (e.g., latitude and longitude coordinates of a Global Positioning System (GPS)). Other methods for determining and identifying sensing areas can be implemented similarly.

[0050] In some deployments, due to differences in the capabilities of the sensing measurement unit or business requirements, the request message may indicate not only a list of sensing areas it expects to detect, but also the priority of each sensing area. In some deployments, each of the multiple sets of sensing parameters includes priorities for multiple sensing areas.

[0051] For example, the request from the sensing measurement unit 305 to the sensing control function includes different priorities for each of the sensing regions 310, 320, and 330. Sensing region 310 is associated with a first priority, sensing region 320 with a second priority, and sensing region 330 with a third priority.

[0052] The sensing area can be determined using any suitable method described herein. Priorities describe the order of sensing measurements within the area. In some examples, there are six priorities, identified by values ​​or indices 0-5. In some examples, priority 0 represents the lowest priority, while priority 5 represents the highest priority. Priorities can be determined based on detection quality, sensing area, operational requirements, etc. The sensing measurement unit prioritizes measuring sensing reference signals within sensing areas that have higher priority.

[0053] In some arrangements, different bandwidths and periods of the sensing reference signal are specified for different sensing regions. In some arrangements, each of the multiple sets of sensing parameters includes the bandwidth and period of the sensing reference signal for each of the multiple sensing regions. The sensing period refers to the period during which the sensing measurement unit measures the sensing reference signal within the sensing region. For example, a request from the sensing measurement unit 305 to the sensing control function includes different sensing periods and bandwidths for each of the sensing regions 310, 320, and 330. Sensing region 310 is associated with a first bandwidth and a first period, sensing region 320 is associated with a second bandwidth and a second period, and sensing region 330 is associated with a third bandwidth and a third period.

[0054] Therefore, the request message includes information about at least one sensing area of ​​the sensing measurement unit, or defines the sensing measurement unit, and for each sensing area, the request message includes at least one of priority, bandwidth, and sensing cycle.

[0055] In some configurations, the sensing control function configures the sensing area of ​​the sensing measurement unit based on its capabilities, a measurement request, network quality, or other information. The sensing control function responds to the request by sending a response message to the sensing measurement unit. This response carries a sensing parameter including at least one of the following: signal power (e.g., signal power range), sensing distance (e.g., sensing distance range), sensing direction (e.g., sensing direction range), or sensing time (e.g., sensing time range). In some examples, as described herein, a threshold corresponding to the received power of the sensing reference signal to be measured is used to indicate the range of signal power. In some examples, as described herein, the sensing distance range can be used to indicate the distance range of the sensing reference signal to be measured. In some examples, as described herein, the sensing direction range is used to indicate the directional range of the sensing reference signal to be measured. In some examples, as described herein, the sensing time range is used to indicate the expected time range for measuring the sensing reference signal.

[0056] In some arrangements, the responses transmitted and received at 130 and 140 respectively include one or more of a plurality of sensing regions, each of the plurality of sensing regions being defined by at least one of the following: the signal power of the sensing reference signal, the sensing distance of the sensing reference signal, the sensing direction of the sensing reference signal, or the sensing time of the sensing reference signal, wherein, in response to receiving a response, the sensing reference signal is transmitted in the plurality of sensing regions.

[0057] The sensing area can be determined by the sensing measurement unit using sensing parameters in the response. Multiple sensing areas can be indicated in the response message in a manner similar to that indicated in the request message. For example, the sensing control function configures the sensing measurement unit to detect two sensing areas, including a first sensing area and a second sensing area. Sensing areas can be defined by sensing parameters in the response. For example, the response message includes a list of sensing areas. Each sensing area is indicated by one or more of the following: signal power range, sensing distance range, sensing direction range, and sensing time range.

[0058] Furthermore, due to differences in the capabilities of the sensing and measurement units and business requirements, the sensing control function in the response message can indicate the priority of each sensing area, as described in the section on requests herein. For example, the response from the sensing control function to the sensing and measurement unit includes different priorities for each of the first and second sensing areas. The first sensing area is associated with a first priority, and the second sensing area is associated with a second priority.

[0059] As described in the section on requests in this document, priorities describe the order of sensing measurements within a region. In some examples, there are three priorities, identified by values ​​or indices 0-2. In some examples, priority 0 represents the lowest priority, while priority 2 represents the highest priority. Priorities can be determined based on detection quality, sensing area, business requirements, etc. The sensing measurement unit prioritizes measuring sensing reference signals within sensing areas with higher priorities. In some examples, the request includes multiple sensing areas and priorities for each of these sensing areas.

[0060] As described in the content of this request, in some arrangements, different bandwidths and periods of the sensing reference signal are specified for different sensing regions. As mentioned above, the sensing period refers to the period during which the sensing measurement unit measures the sensing reference signal within the sensing region. For example, the response from the sensing control function to the sensing measurement unit includes different sensing periods and bandwidths for each of a first and a second sensing region. The first sensing region is associated with a first bandwidth and a first period, while the second sensing region is associated with a second bandwidth and a second period. In some examples, the request includes multiple sensing regions and the bandwidth and period for sensing the sensing reference signal for each of the multiple sensing regions.

[0061] Therefore, the response message includes information about at least one sensing area of ​​the sensing measurement unit, or defines the sensing measurement unit, and for each sensing area, the request message includes at least one of priority, bandwidth, and sensing period.

[0062] In some arrangements, information exchange can be performed in a single-station sensing mode. A single-station sensing mode refers to a device that performs both the transmission and reception of sensing reference signals. In some arrangements, at location 150, after the sensing measurement unit 102 transmits sensing reference signals across multiple sensing areas, the sensing measurement unit 102 receives reflected or scattered signals corresponding to the sensing reference information and measures the reflected or scattered signals.

[0063] Figure 4 This is a schematic diagram illustrating an example method 400 for performing sensing in a single-site sensing mode according to various arrangements. In the single-site sensing mode, a sensing measurement unit 405 (e.g., a BS or UE) transmits a sensing reference signal 410 toward an environment 430 (e.g., the transmitting sensing area and the receiving sensing area of ​​the sensing measurement unit 405) and receives a corresponding reflected or scattered wave or signal 420 corresponding to the sensing reference signal 410, wherein the sensing reference signal 410 is reflected or scattered by the environment 430.

[0064] In some examples, the sensing measurement unit sends a measurement request in which at least one sensing area is defined or identified using sensing parameters (e.g., signal power range, sensing distance range, sensing direction range, or sensing time range). In examples where at least one sensing area comprises multiple sensing zones, the request message may use sensing parameters (e.g., signal power range, sensing distance range, sensing direction range, or sensing time range) to define or identify each of the multiple sensing zones.

[0065] Furthermore, due to differences in the capabilities of the sensing measurement unit or business requirements, the sensing measurement unit in the request message not only indicates a list of sensing areas that the sensing measurement device is configured to detect, but also indicates the priority, bandwidth, or one or more of the sensing cycles for each sensing area relative to the sensing reference signal.

[0066] As described in the request section of this document, priority describes the priority of sensing measurements within a region. In some examples, there are five priorities, identified by values ​​or indices 0 through 4. In some examples, priority 0 represents the lowest priority, while priority 4 represents the highest priority. Priorities can be determined based on detection quality, sensing area, service requirements, etc. The sensing measurement unit prioritizes measuring sensing reference signals within sensing areas with higher priority. As described in the request section of this document, in some arrangements, different bandwidths and periods of the sensing reference signals are specified for different sensing areas.

[0067] In response to a request received from a sensing measurement unit, the sensing control function configures the measurement of the sensing measurement unit based on the request from the sensing measurement unit, the capacity of the sensing measurement unit, and the need for data fusion from multiple sensing measurement units.

[0068] In some configurations, the sensing control function may indicate in the measurement response message 1) the sensing area, 2) each sensing area and its measurement priority, 3) each sensing area and its measurement period, and its time-frequency domain resources (e.g., bandwidth), or 4) each sensing area and its measurement priority, its measurement period, and its time-frequency domain resources.

[0069] Figure 5 This is a signaling schematic diagram illustrating example methods for configuring sensing according to various arrangements. At 510, the sensing measurement unit 502 sends a sensing measurement request (or request, request message) to the sensing control function 504. At 520, the sensing control function 504 sends a sensing measurement response (or response, response message) to the sensing measurement unit 502.

[0070] In some arrangements, information exchange can be performed in a dual-station sensing mode. Dual-station sensing mode refers to a first device sending a sensing reference signal, while a second device receives the reflected or scattered signal. In some arrangements, the reflected or scattered signal corresponding to the sensing reference signal is received by a different sensing measurement unit than sensing measurement unit 102. This other sensing measurement unit measures the reflected or scattered signal.

[0071] Figure 6 This is a schematic diagram illustrating an example method 600 for performing sensing in a dual-site sensing mode according to various arrangements. In the dual-site sensing mode, a sensing measurement unit 605a (e.g., a first BS or a first UE) transmits a sensing reference signal 610 to the environment 630 within a sensing area (e.g., the transmitting sensing area of ​​sensing measurement unit 605a and the receiving sensing area of ​​sensing measurement unit 605b). A sensing measurement unit 605b (e.g., a second BS or a second UE) receives a corresponding reflected or scattered wave or signal 620 corresponding to the sensing reference signal 610. The sensing reference signal 610 is reflected or scattered by the environment 630.

[0072] In one example, perception measurement unit 605a is a base station (BS) and perception test unit 605b is a user (UE). In another example, perception measurement unit 605a is a first base station and perception test unit 605b is a second base station. In yet another example, perception measurement unit 605a is a first UE and perception test unit 605b is a second UE. In yet another example, perception measurement unit 605a is a UE and perception test unit 605b is a BS.

[0073] In some examples, the sensing measurement unit 605a, acting as a transmitter of the sensing reference signal 610, is a sensing transmitter. The sensing measurement unit 605b, acting as a receiver of the reflected or scattered wave of signal 620, is a sensing receiver. In some examples, when both sensing measurement units 605a and 605b are BSs (e.g., BS transmit BS receive mode), in one sensing transmission, the first BS is a sensing transmitter, and the second BS is a sensing receiver. In another sensing transmission, the first BS is a sensing receiver, and the second BS is a sensing transmitter. Therefore, a sensing measurement unit that can be either a sensing transmitter or a receiver can independently request to transmit and receive sensing measurements. In some examples, the sensing measurement unit can request sensing transmission measurement configuration and sensing reception measurement configuration in one message or different messages. In some arrangements, the sensing measurement unit 102 sends a first message requesting sensing transmission measurement configuration to the sensing control function 104, and the sensing control module 104 receives the first message requesting sensing transmission measurement configuration from the sensing measurement module 102. The sensing and measurement unit 102 sends a second message requesting the sensing and receiving measurement configuration to the sensing and control function 104, and the sensing and control module 104 receives the second message requesting the sensing and receiving measurement configuration from the sensing and measurement module 102. The first message and the second message are different messages or the same message.

[0074] For a configuration of sensing transmission measurement and sensing reception measurement, the sensing measurement unit sends a measurement request that includes at least one of a transmitting sensing region or a receiving sensing region. The transmitting and receiving sensing regions are respectively indicated by one or more sensing parameters (e.g., signal power range, sensing distance range, sensing direction range, and sensing time range). In some arrangements, the request includes at least one transmitting sensing region or at least one or more receiving sensing regions. Each of the at least one transmitting sensing region is defined by a first sensing parameter. Each of the at least one receiving sensing region is defined by a second sensing parameter. Each of the first and second sensing parameters includes at least one of the following: the signal power of the sensing reference signal, the sensing distance of the sensing reference signal, the sensing direction of the sensing reference signal, or the sensing time of the sensing reference signal.

[0075] In some configurations, multiple transmitting sensing areas and multiple receiving sensing areas can be indicated in the request message. For example, the sensing measurement unit requests to detect two transmitting sensing areas and two receiving sensing areas, and includes a list of these sensing areas in the request message.

[0076] In some arrangements, due to differences in the capabilities or operational requirements of the sensing measurement unit, the sensing measurement unit, in its request message, indicates not only a list of sensing areas configured for detection by the sensing measurement device, but also one or more of the following: priority, bandwidth, or sensing period for a sensing reference signal for each sensing area. In some arrangements, the request includes at least one of the following: priority for each of at least one transmitting sensing area or each of at least one receiving sensing area; bandwidth for at least one transmitting sensing area or each receiving sensing area; and the period for sensing the sensing reference signal for at least one transmitting sensing area and each receiving sensing area.

[0077] As described in the request section of this document, priority describes the priority of sensing measurements within a region. In some examples, there are two priorities, identified by values ​​or indices 0 to 1. In some examples, priority 0 represents the lowest priority, while priority 1 represents the highest priority. Priorities can be determined based on detection quality, sensing area, business requirements, etc. The sensing measurement unit prioritizes measuring sensing reference signals within sensing areas with higher priority. As described in the request section of this document, in some arrangements, different bandwidths and periods of the sensing reference signals are specified for different sensing areas.

[0078] When the perception control function receives a request from the perception measurement unit, it configures the measurement of the perception measurement unit based on the measurement request from the perception measurement unit, the capacity of the perception measurement unit, and the need for data fusion from multiple perception measurement units.

[0079] In some configurations, the sensing control function may indicate in the measurement response message 1) the sensing area, 2) each sensing area and its measurement priority, 3) each sensing area and its measurement period, and its time-frequency domain resources (e.g., bandwidth), or 4) each sensing area and its measurement priority, its measurement period, and its time-frequency domain resources.

[0080] In some configurations, sensing measurement unit 605a includes a BS (Browser Controller), and sensing measurement unit 605b includes a UE (User Equipment). The BS plans to measure five areas (e.g., sensing areas 1-5) based on its capabilities and service requirements. The BS indicates the desired sensing areas in a request message. Furthermore, the BS can indicate the priority of these sensing areas or the measurement configuration of these sensing areas (including the bandwidth of the sensing reference signal, the period of the sensing reference information, etc.). Additionally, the BS can indicate combinations of different types of information (e.g., sensing parameters) that can be defined, identified, or configured for these sensing areas.

[0081] In some arrangements, the sensing measurement unit 102 includes a BS. A reflected or scattered signal corresponding to the sensing reference signal is received by another sensing measurement module, which measures the reflected or scattered signal. The other sensing measurement unit includes a UE.

[0082] The perception control function is determined based on the BS's request and business requirements or other information. The BS only needs to measure four of the five perception areas (e.g., perception areas 1-4). In the response message, the perception control function indicates information about these four perception areas (e.g., perception parameters). In addition, the perception control function can indicate at least one of the following for each of the four perception areas (e.g., perception areas 1-4): priority, bandwidth, or perception cycle.

[0083] The UE connects to the BS and receives a message from the BS or the perception control function indicating that the BS will perceive four perception areas (e.g., perception areas 1-4). The UE sends a response to the BS or the perception control function, indicating that the UE can perform perception in perception areas 1 and 2. Therefore, the UE becomes a perception measurement unit 605b.

[0084] In some deployments, the sensing control function configures detection parameters. In wireless sensing, it is assumed that the object being sensed is not connected to the network, and it is impossible to know whether the target exists before sensing. Therefore, in sensing, the presence of the object is determined. However, due to the limited sensing range of a single device and the possibility of blind spots, wireless sensing leverages the wide-area coverage of mobile communications and the characteristics of numerous UEs. Multiple sensing measurement units can jointly sense and detect targets in the environment. To integrate and process the sensing data from multiple sensing measurement units, the network defines parameters for processing received reflected or scattered signals in a unified manner.

[0085] In different application scenarios, humans, vehicles, drones, and buildings within the sensing area can be detected. Different UEs have different detection angles, accuracy, range, capabilities, and algorithms. When different UEs extract information from the sensing reference signal, differences in information accuracy and detection thresholds may occur.

[0086] Figure 7This diagram illustrates an example method 700 for performing sensing in a sensing mode according to various arrangements. A sensing measurement unit (e.g., a first BS or a first UE) transmits a sensing reference signal toward an environment 730 located within a sensing area (e.g., the transmitting sensing area of ​​the sensing measurement unit and the receiving sensing area of ​​sensing measurement units 705a, 705b, and 705c). Sensing measurement units 705a, 705b, and 705c (e.g., a second BS or a second UE) receive corresponding reflected or scattered waves or signals 620 corresponding to the sensing reference signal. The sensing reference signal is reflected or scattered by the environment 730. In other words, sensing measurement units 705a, 705b, and 705c are used to detect the same area. A sensing control function configures detection thresholds for sensing measurement units 705a, 705b, and 705c to control their processing of the received reflected or scattered signals.

[0087] The sensing control function or BS can send messages to each of the sensing measurement units 705a, 705b, and 705c to instruct the measurement configuration of the sensing measurement units 705a, 705b, and 705c. In some arrangements, the measurement configuration includes at least one of a detection threshold or a sensing area (e.g., corresponding to or surrounding environment 730).

[0088] In some arrangements, a detection threshold may be used by a sensing measurement unit to receive reflected or scattered signals to determine the presence of at least one object. In response to determining that the power of the reflected or scattered signal exceeds the detection threshold, the sensing measurement unit determines that an object is present.

[0089] In some arrangements, the sensing measurement unit 102 receives a measurement configuration from the sensing control function 104 for measuring reflected or scattered signals corresponding to a sensing reference signal, and the sensing control module 104 sends the measurement configuration to the sensing measurement module 102. The sensing control function 104 sends a corresponding measurement configuration to each of a plurality of sensing measurement units measuring reflected or scattered signals. In some arrangements, the measurement configuration includes at least one of the following: a detection threshold and a plurality of sensing regions. The detection threshold defines a power threshold for the reflected or scattered signal corresponding to the presence of at least one object.

[0090] In some examples, different detection thresholds are configured for different areas due to varying sensing distances. Therefore, the sensing control function or the BS configures different sensing thresholds for the UE to detect different sensing areas. The sensing control function or the BS instructs the UE on the measurement processing configuration information in the measurement configuration message.

[0091] In some configurations, even if sensing measurement units 705a, 705b, and 705c all detect the same sensing area, the power of reflected or scattered signals to them varies due to differences in their distances from the sensing area. In examples with significant power differences, sensing measurement units 705a, 705b, and 705c are not suitable for processing with the same detection threshold. Therefore, the sensing control function or the BS sets different detection thresholds for the same sensing area in the measurement configuration message based on the quality of data fusion or other factors.

[0092] As described in this article, the sensing area is indicated in the measurement configuration message by one or more sensing parameters (e.g., signal power range, sensing distance range, sensing direction range, and sensing time range).

[0093] Furthermore, the perception control function or BS can separately indicate detection thresholds for multiple perception areas. For example, the perception control function or BS can indicate detection thresholds for two perception areas (e.g., a first perception area and a second perception area) to the perception measurement unit. The perception control function or BS sends a measurement configuration message carrying information about the two perception areas and their respective detection thresholds. That is, the measurement configuration message can identify the first perception area and its corresponding first detection threshold, and the second perception area and its corresponding second detection threshold.

[0094] The detection thresholds for different sensing regions can be the same or different. Some examples describe indication methods for two sensing regions. When the UE supports more sensing regions, it can carry multiple sensing regions and detection thresholds as described.

[0095] In some configurations, sensing areas can be implicitly configured. The sensing and measurement unit can send sensing and measurement resources to sense the environment or target. Figure 8 This is a schematic diagram illustrating a sensing and measurement unit 805 configured to perform sensing using beams 810-1, 810-2, 810-3, ..., 810-n according to various arrangements. The sensing and measurement unit 805 (e.g., a sensing transmitter) transmits n beams 810-1, 810-2, 810-3, ..., 810-n for sensing and measurement. Each of the beams 810-1, 810-2, 810-3, ..., 810-n corresponds to the sensing direction of the antenna panel of the sensing and measurement unit 805. Each of the beams 810-1, 810-2, 810-3, ..., 810-n corresponds to a sensing and measurement resource.

[0096] Figure 9This is a signaling schematic diagram illustrating an example method 900 for configuring sensing measurement resources according to various arrangements. At 910, the sensing measurement unit 805 sends a sensing measurement resource message to the sensing control function 902. The sensing measurement resource message includes information about the sensing measurement resources that the sensing measurement unit 805 will send. At 920, the sensing control function 902 configures the sensing measurement unit 905 (e.g., a sensing receiver) to measure the sensing measurement resources according to the sensing measurement resources of the sensing measurement unit 805. The sensing measurement unit 905 can also use information about the target being measured and information from the sensing measurement unit 905 by sending the sensing measurement resource configuration 920 to the sensing measurement module 905. The information about the target being measured is based on previous measurement procedures. In some examples, the sensing measurement unit 805 notifies the sensing control function 902 of the sensing measurement resources corresponding to n beams 810-1, 810-2, 810-3, ..., 810-n, and the sensing control module 902 configures the measurement resources of the sensing measurement unit 905 to instruct the sensing measurement unit 905 to only measure the sensing resources corresponding to a subset of beams (e.g., beams 810b and 810c).

[0097] In some examples, the perception measurement unit 102 sends a perception measurement resource message, including at least one perception resource, to the perception control function 104, and the perception control module 104 receives the message from the perception measurement unit 102. The perception control function sends a perception measurement resource configuration, including one or more of the at least one perception resource, to another perception measurement unit. The perception measurement unit is a perception transmitter, and the other perception measurement unit is a perception receiver. In some examples, one or more of the at least one perception resource sent by the perception control function 104 to the other perception measurement unit is a subset of the at least one perception resource received by the perception control function 104 from the perception measurement unit 102.

[0098] In some examples, sensing measurement unit 102 sends a sensing measurement resource configuration, including one or more of at least one sensing resource, to another sensing measurement unit, which receives the configuration from sensing measurement unit 102. The sensing measurement unit is a sensing transmitter, and the other sensing measurement unit is a sensing receiver.

[0099] Traditionally, sensing measurement units such as UEs typically select the optimal measurement resources for measurement. However, during the sensing process, the coverage of different beams varies. The target being measured may not be within the coverage of the strongest beam. If measurement feedback is given based on the strongest beam, the information measured by the sensing measurement unit will not include the target being sensed, leading to missed detections.

[0100] In the arrangement disclosed herein, the perception control function configures the perception resources that each perception measurement unit needs to measure, and optimizes the measurement process of the perception measurement unit through network configuration to improve measurement efficiency and accuracy.

[0101] In some configurations, n beams 810-1, 810-2, 810-3, ..., 810-n transmitted by the sensing measurement unit 805 (sensing transmitter) are aimed at multiple sensing measurement units 905, and the sensing measurement unit 805 instructs each sensing measurement unit 905 (sensing receiver) on the sensing resources that each sensing measurement unit 905 needs to measure. The sensing measurement resources configured by the sensing measurement unit 805 for the sensing measurement unit 905 UE to be measured are a subset of the sensing measurement resources transmitted by the sensing measurement module 805. Figure 10 This is a signaling schematic diagram illustrating an example method 1000 for configuring sensing resources according to various arrangements. At 1010, sensing measurement unit 805 sends a sensing measurement resource configuration 1010 to sensing measurement unit 905, which includes the sensing resources that each sensing measurement unit 905 needs to measure within the sensing area. Sensing measurement unit 905 uses the sensing resources to measure reflected or scattered signals and reports the measurement results to sensing measurement unit 805 and / or sensing control function.

[0102] Similarly, if the sensing measurement unit 805 (sensing transmitter) transmits n beams 810-1, 810-2, 810-3, ..., 810-n for sensing measurement, and the sensing measurement unit 905 (sensing receiver) receives and measures these beams, then the sensing measurement unit 805 reports the sensing measurement resources corresponding to the n beams 810-1, 810-2, 810-3, ..., 810-n to the sensing control function. The sensing control function configures the sensing resources to be measured for the sensing measurement unit 905. The sensing measurement resources configured by the sensing control function for the sensing measurement unit 905 are a subset of the sensing measurement resources transmitted by the sensing measurement unit 805.

[0103] In some setups, sensing measurement paths can be configured. The transmission of the SL PRS (Sidelink Positioning Reference Signal) can communicate via multiple transmission paths, including line-of-sight (LOS) paths and non-line-of-sight (NLOS) paths reflected by other objects (such as walls). These multiple paths arrive at the receiver at different times. Existing positioning measurements are typically based on a first path. However, in sensing, the first path may not be the path reflected or scattered by the measured target, but rather the surrounding environment. Furthermore, there may be multiple measured targets, each at a different distance from the sensing receiver, resulting in different arrival times for the sensing receiver via paths from multiple measured targets. Therefore, in sensing, obtaining only measurement information from the first path is inaccurate. Feedback of all measurement information may not be necessary, as ambient signals are not helpful for sensing. On the other hand, excessive feedback information can overburden the transmission.

[0104] In some arrangements, one sensing measurement unit is a sensing transmitter, and another sensing unit is a sensing receiver. The network (sensing control function or BS) uses a sensing measurement feedback configuration to configure the sensing measurement feedback. This configuration includes at least a measurement threshold. The measurement threshold can be the measured signal strength (e.g., a range of Reference Signal Received Power (RSRP)), distance (e.g., a distance range), Doppler value (e.g., a range of Doppler values), or a combination of these measurement thresholds. The Doppler threshold is a threshold for the frequency shift caused by the Doppler effect. This range can be defined by a minimum, a maximum, or a combination of both. For example, the measurement threshold configured by the network is an RSRP threshold. When the measurement threshold indicates the minimum of the RSRP threshold, the second sensing measurement unit measures reflection or scattering paths exceeding the RSRP and provides its feedback. If the measurement threshold can be a combination of multiple thresholds, e.g., indicating both an RSRP threshold and a distance threshold, the second sensing measurement unit measures paths that satisfy both thresholds and provides its feedback. The network (e.g., the sensing control function) can instruct the measurement of multiple (e.g., the first N) reflection or scattering paths.

[0105] In some examples, the sensing measurement unit 102 receives a sensing measurement feedback configuration, including measurement thresholds, from the sensing control function 104, while the sensing control module 104 sends this configuration to the sensing measurement unit 102. The measurement thresholds include at least one of a signal strength threshold, a distance threshold, and a Doppler threshold. In some examples, the sensing measurement unit 102 sends feedback corresponding to a reflected or scattered signal of a sensing reference signal to the sensing control function 104 according to the sensing measurement feedback configuration, while the sensing control function 104 receives this feedback from the sensing measurement unit 102.

[0106] Figure 11 Block diagrams of example BS 1100 and example UE 1120 according to various arrangements are shown. BS 1100 is a network node, such as an evolved node B (eNB), a g node B (gNB), a femtocell, a picocell, a reconfigurable intelligent surface (RIS), a relay node, an integrated access and backhaul (IAB) node, a network controlled repeater (NCR) node, and so on. BS 1100 includes a transceiver module 1110, an antenna 1112, a processor module 1114, a memory module 1116, and a network communication module 1118, and each module is coupled and interconnected with each other as needed via a data communication bus 1111. UE 1120 (e.g., a wireless communication device) includes a transceiver module 1130, an antenna 1132, a memory module 1134, and a processor module 1136, each module being coupled and interconnected with each other as needed via a data communication bus 1140. BS 1100 communicates with UE 1120 via a communication channel, link, connection, or beam, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0107] As will be understood by those skilled in the art, BS 1100 and UE 1120 may also include, in addition to Figure 11Any number of modules other than those shown herein. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are typically described according to their functionality. Whether this functionality is implemented as hardware, firmware, or software depends on the specific application and the design constraints imposed on the system as a whole. Those skilled in the art can implement these functions appropriately for each specific application, but these implementation decisions should not be construed as limiting the scope of this disclosure.

[0108] According to some embodiments, transceiver 1130 may be referred to herein as an uplink transceiver 1130 including a radio frequency (RF) transmitter and an RF receiver, each transmitter and receiver including circuitry coupled to antenna 1132. A duplex switch (not shown) may alternately couple the uplink transmitter or receiver to the uplink antenna in a time-duplex manner. Similarly, according to some embodiments, transceiver 1110 may be referred herein as a downlink transceiver 1110 including an RF transmitter and an RF receiver, each RF transmitter and RF receiver including circuitry coupled to antenna 1112. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 1112 in a time-division duplex manner. The operation of the two transceiver modules 1110 and 1130 may be time-coordinated such that the uplink receiver circuitry is coupled to the uplink antenna 1132 so that transmissions are received over a wireless transmission link while the downlink transmitter is coupled to the downlink antenna 1112. In some implementations, there is tight time synchronization between changes in the duplex direction with a minimum protection time.

[0109] Transceiver 1130 and transceiver 1110 are configured to communicate via a wireless data communication link (e.g., a channel, connection, and beam) and cooperate with an RF antenna arrangement 1112 / 1132 appropriately configured to support a specific wireless communication protocol and modulation scheme. In some illustrative embodiments, transceiver 1110 and transceiver 1110 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G / 6G standards. However, it should be understood that this disclosure is not necessarily limited to application to specific standards and associated protocols. Rather, transceiver 1130 and transceiver 1110 may be configured to support alternative or additional wireless data communication protocols (including future standards or variations thereof).

[0110] In some implementations, UE 1120 can be various types of messaging clients, such as mobile phones, smartphones, personal digital assistants (PDAs), tablets, laptops, wearable computing devices, etc. Processor modules 1114 and 1136 can be implemented or realized using a general-purpose processor, content-addressable memory, digital signal processor, application-specific integrated circuit, field-programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. In this way, the processor can be implemented as a microprocessor, controller, microcontroller, state machine, etc. The processor can also be implemented as a combination of computing devices, such as a digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors combined with a digital signal processor core, or any other combination of such configurations.

[0111] Furthermore, the steps of the methods or algorithms described in conjunction with the embodiments disclosed herein can be directly implemented in hardware, firmware, software modules executed by processor modules 1114 and 1136 respectively, or any actual combination thereof. Memory modules 1116 and 1134 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this respect, memory modules 1116 and 1134 can be coupled to processor modules 1110 and 1130 respectively, such that processor modules 1110 and 1130 can read information from and write information to memory modules 1116 and 1134 respectively. Memory modules 1116 and 1134 can also be integrated into their respective processor modules 1110 and 1130. In some embodiments, memory modules 1116 and 1134 may each include cache memory for storing temporary variables or other intermediate information during the execution of instructions executed by processor modules 1110 and 1130, respectively. Memory modules 1116 and 1134 may also each include non-volatile memory for storing instructions to be executed by processor modules 1110 and 1130, respectively.

[0112] Network communication module 1118 typically represents the hardware, software, firmware, processing logic, and / or other components of BS 1100 that enable bidirectional communication between transceiver 1110 and other network components and communication nodes (e.g., other nodes such as BS 1100) configured to communicate with BS 1100. For example, network communication module 1118 may be configured to support Internet or WiMAX (World Interoperability for Microwave Access) services. In a typical deployment, but without limitation, network communication module 1118 provides an 802.3 Ethernet interface, allowing transceiver 1110 to communicate with traditional Ethernet-based computer networks. In this way, network communication module 1118 may include a physical interface for connecting to a computer network (e.g., a Mobile Switching Center (MSC)). The terms “configured as,” “configured to,” and their variations, used in this document in relation to a specified operation or function refer to a device, component, circuit, structure, machine, signal, etc., which is physically constructed, programmed, formatted, and / or arranged to perform a specified operation or function.

To clearly illustrate this interchangeability of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software, or a combination of these technologies, depends on the specific application and the design constraints imposed on the system as a whole.
