[0001] The disclosure relates generally to wireless sensing and, more particularly, to sensing measurements.BACKGROUND
[0002] From the first-generation analog communication to the fifth-generation mobile communication system of the Internet of Everything, mobile communication has not only profoundly changed people's lifestyles, but has also become a new engine for accelerating the improvement of society's digital level. With the continuous emergence of new services and new demands, mobile communication systems can provide increasingly powerful communication capabilities. Among them, wireless sensing is an important potential direction. Compared with two independent systems, the integrated design of communication and sensing can reduce costs, reduce power consumption, and optimize resource utilization. Integrated Sensing and Communication (ISAC) achieves unified design of communications and sensing control functions through signal joint design and / or hardware sharing. Sensing in ISAC can be understood as a wireless sensing technology based on mobile communication systems. A mobile communication system can send wireless signals and analyzes the reflected waves or scattered waves of the wireless signals to obtain corresponding sensing measurement data.SUMMARY

[0024] Some arrangements relate to a sensing control function and a sensing measurement unit. In some arrangements, a sensing control function (or a sensing function) can be a new logical function (e.g., software, firmware, application, operation, or processes) of the Core Network (CN) or an enhancement or addition of an existing logical function, such as the Location Management Function (LMF) of the CN. In some examples, the sensing control function can be a functional module of (e.g., software, firmware, application, operation, or processes executed on) a Radio Access Network (RAN) . That is, the sensing control function can be implemented on a Base Station (BS) or a User Equipment (UE) in some arrangements. In some arrangements, the sensing measurement unit can be a BS, a UE, or another suitable wireless communication device, wireless communication node, or so on.
[0025] FIG. 1A is a flowchart diagram illustrating an example method 100a for configuring sensing, according to various arrangements.

For example, the sensing measurement unit 102 can be a sensing transmitter that sends the sensing reference signals to the sensing receiver, which can be a sensing measurement unit such as the sensing measurement unit 102 (e.g., a BS, a UE, or another network node) .
[0028] FIG. 1B is a flowchart diagram illustrating an example method 100b for configuring sensing, according to various arrangements. The method 100b can be performed by a first sensing measurement unit 106, according to various arrangements.
[0029] At 160, the first sensing measurement unit 106 receives from a sensing control function (e.g., the sensing control function 104) or a second sensing measurement unit (e.g., the sensing measurement unit 102) , a request for performing sensing measurements. The request includes a plurality of sets of sensing parameters that defines a plurality of sensing regions. Each of the plurality of sets of sensing parameters defines a respective one of the plurality of sensing regions. At 170, the first sensing measurement unit 106 measures one or more sensing reference signals based on plurality of sensing regions.
[0030] In some arrangements, the first sensing measurement unit 106 reports measurement results associated or within each of the plurality of sensing regions. In some arrangements, the first sensing measurement unit 106 does not report measurement results for an area outside the plurality of sensing regions. In some arrangements, the plurality of sets of sensing parameters of sensing measurements indicates a plurality of sensing reference signals. In some arrangements, the first sensing measurement unit reports results for each of the plurality of sensing reference signals. In some arrangements, the first sensing measurement unit 106 does not report results for a sensing reference signal different from the plurality of sensing reference signals.
[0031] In some arrangements, each set of the plurality of sets of sensing parameters includes, for each of the plurality of sensing regions, at least one of a signal power of the sensing reference signals, a sensing distance of the sensing reference signals, a sensing direction of the sensing reference signals, a sensing time of the sensing reference signal, a sensing phase of the sensing reference signal, or a Doppler of the sensing reference signal.
[0032] In some arrangements, the signal power includes a range of signal powers, wherein the range of signal powers is defined by at least one of a minimum threshold of the range of signal powers, a maximum threshold of the range of signal powers, or a combination of the minimum threshold of the range of signal powers and the maximum threshold of the range of signal powers.

The sensing phase includes a range of sensing phases. The range of sensing phases is defined by at least one of a minimum phase of the range of sensing phases, a maximum threshold of the range of sensing phases, or a combination of the minimum phase of the range of sensing phases and the maximum phase of the range of sensing phases. The Doppler includes a range of sensing Dopplers, wherein the range of sensing Dopplers is defined by at least one of a minimum Doppler of the range of sensing Dopplers, a maximum threshold of the range of sensing Dopplers, or a combination of the minimum Doppler of the range of sensing Dopplers and the maximum Doppler of the range of sensing Dopplers.
[0033] In some arrangements, of the plurality of sets of sensing parameters includes a priority level for each of the plurality of sensing regions. In some arrangements, each of the plurality of sets of sensing parameters includes a bandwidth and a period for the sensing reference signals for each of the plurality of sensing regions.
[0034] In some arrangements, the first sensing measurement unit 106 receives a reflected or scattered signal corresponding to the 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, measurement configuration for measuring a reflected or scattered signal corresponding to the sensing reference signals.
[0036] In some arrangements, the measurement configuration includes at least one of a detection threshold. The detection threshold defines a power threshold of the reflected or scattered signal that corresponds to a presence of at least one object. In some arrangements, the first sensing measurement unit 106 reports the sensing measurement result based on the detection threshold.
[0037] FIG. 1C is a flowchart diagram illustrating an example method 100c for configuring sensing, according to various arrangements. The method 100c can be performed by a sensing control function 104, according to various arrangements. At 180, the sensing control function 104 receives from the second sensing measurement unit a report for performing sensing measurements. The report includes a plurality of sets of sensing parameters of sensing reference signals that defines a plurality of sensing regions. At 190, the sensing control function 104 sends to the first sensing measurement unit 106, a request. The request includes a plurality of sets of sensing parameters of sensing measurements that defines a plurality of sensing regions.
[0038] In some arrangements, the report is for reference signal transmission. The report includes a plurality of sets of sensing parameters that defines a plurality of sensing regions. Each of the plurality of sets of sensing parameters defines a respective one of the plurality of sensing regions for the sensing reference signal transmission. In some arrangements, the plurality of sets of sensing parameters of sensing measurements is subset of the plurality of sets of sensing parameters of sensing reference signals.
[0039] In some examples, a sensing measurement unit sends a request to a sensing control function. The request includes at least one of a signal power (e.g., a range of signal powers) , a sensing distance (e.g., a range of sensing distances) , a sensing direction (e.g., a range of sensing directions) , or a sensing time (e.g., a range of sensing times) . In some examples, a range of signal powers is indicated using a threshold corresponding to a received power of a sensing reference signal to be measured. In some examples, a range of sensing distances can be used to indicate a distance range of a sensing reference signal to be measured. In some examples, the range of sensing directions is used to indicate a direction range of a sensing reference signal to be measured. In some examples, the range of sensing times is used to indicate an expected time range for measuring a sensing reference signal.
[0040] In some examples, for indicating the range of signal powers, a minimum threshold can be used to indicate the sensing reference signals that are to be detected exceed this minimum threshold. In other words, the range of signal power is a range with a lower bound that is or above the minimum threshold. In some arrangements, the minimum threshold indicates that the sensing measurement unit is expected to detect sensing reference signals that exceed the minimum threshold. For example, in response to determining that a 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 the detected signal. In some examples, for indicating the range of signal powers, a maximum threshold can be used to indicate the sensing reference signals that are to be detected do not exceed this minimum threshold. In some examples, the range of signal powers can be defined by a minimum threshold (or value) , a maximum threshold (or value) , or a combination of the minimum and maximum values. That is, in some arrangements, the sensing measurement unit expects that a signal power of a detected signal is between the minimum and maximum thresholds. The sensing measurement unit otherwise does not report the sensing reference signal with a signal power that is not between the minimum and maximum thresholds.
[0041] In some examples, for indicating the range of sensing distance, distance units such as meters, kilometers, miles, etc. are used. A minimum distance can be used to indicate the sensing reference signals that are to be detected is not less than the minimum distance. In the example, the range of sensing distance defined by a minimum distance of 200 m indicates that the sensing measurement unit wishes to detect sensing reference signals with a distance of no less than 200 m. The sensing measurement unit ignores or does not report signals having a distance that is greater than 200 m. In some examples, a maximum distance can be used to indicate the sensing reference signals that are to be detected is less than the maximum distance. The range of sensing distances can be defined by a minimum distance (e.g., 100 m, 200m, and so on) , a maximum distance (e.g., 500 m) , or a combination of the minimum and maximum distances. That is, in some arrangements, the sensing measurement unit expects that a sensing distance of a detected signal is between the minimum and maximum thresholds. The sensing measurement unit otherwise does not report the sensing reference signal with a sensing distance that is not between the minimum and maximum thresholds.
[0042] In some examples, for indicating the range of sensing directions, the sensing measurement unit can report the range of sensing directions based on the direction or capability of an antenna panel of the sensing measurement unit, which may correspond to a direction, a range of directions, an angle, or a range of angles. The sensing measurement unit indicates the range of sensing direction.
[0043] In some examples, the range of sensing times is a delay range of the expected measurement signals. The delay is defined as a delay of an air port, which is the delay from the sensing transmitter sending the sensing reference signals to the sensing receiver receiving the sensing reference signals. The sensing time is measured in units of time, such as seconds, milliseconds, nanoseconds, etc. The range of sensing times can be defined by a minimum time (e.g., 20 μs) indicating that a minimum delay of a signal that the sensing measurement unit expects to detect. The range of sensing times can be defined by a maximum time (e.g., 100 μs) indicating that a maximum delay of a signal that the sensing measurement unit expects to detect. The range of sensing times can be defined by a minimum time, a maximum time, or a combination of the minimum and maximum times. That is, in some arrangements, the sensing measurement unit expects to detect the sensing reference signal with the sensing time (e.g., delay) that is between the minimum and maximum times. The sensing measurement unit otherwise does not report the sensing reference signal with a sensing time that is not between the minimum and maximum times.
[0044] In some arrangements, a signal power of the sensing reference signal, a sensing distance of the sensing reference signal, a sensing direction of the sensing reference signal, and a sensing time of the sensing reference signal can be collectively referred to as sensing parameters. The request message can carry multiple values of the sensing parameters, which jointly indicate a sensing region. In some arrangements, each set of the plurality of sets of sensing parameters includes, for each of the plurality of sensing regions, at least one of a signal power of the sensing reference signals, a sensing distance of the sensing reference signals, a sensing direction of the sensing reference signals, a sensing time of the sensing reference signal, a sensing phase of the sensing reference signal, or a Doppler of the sensing reference signal.
[0045] In some arrangements, the signal power includes a range of signal powers, wherein the range of signal powers is defined by at least one of a minimum threshold of the range of signal powers, a maximum threshold of the range of signal powers, or a combination of the minimum threshold of the range of signal powers and the maximum threshold of the range of signal powers. The sensing distance includes a range of sensing distances, wherein the range of sensing distances is defined by at least one of a minimum threshold of the range of sensing distances, a maximum threshold of the range of sensing distances, or a combination of the minimum threshold of the range of sensing distances and the maximum threshold of the range of sensing distances. The sensing direction includes a range of sensing directions, wherein the range of sensing directions is determined based on direction or capability of an antenna panel of the sensing measurement unit. The sensing time is a delay from the second sensing measurement unit to the first sensing measurement unit, the sensing time includes a range of sensing times, wherein the range of sensing times is defined by at least one of a minimum time of the range of sensing times, a maximum threshold of the range of sensing times, or a combination of the minimum time of the range of sensing times and the maximum threshold of the range of sensing times. The sensing phase includes a range of sensing phases. The range of sensing phases is defined by at least one of a minimum phase of the range of sensing phases, a maximum threshold of the range of sensing phases, or a combination of the minimum phase of the range of sensing phases and the maximum phase of the range of sensing phases. The Doppler includes a range of sensing Dopplers, wherein the range of sensing Dopplers is defined by at least one of a minimum Doppler of the range of sensing Dopplers, a maximum threshold of the range of sensing Dopplers, or a combination of the minimum Doppler of the range of sensing Dopplers and the maximum Doppler of the range of sensing Dopplers.
[0046] FIG. 2 is a diagram illustrating a sensing region 200, according to various arrangements. For example, the sensing region 200 is defined by sensing parameters carried in the request message, which includes the sensing direction defined by a sensing degree range 210 and a distance range 220 relative to the sensing measurement unit 205. In some examples, the sensing degree range 210 is [0°, 30°] and the sensing distance range 220 is [300 m, 400 m] . The sensing degree range 210 and the sensing distance range 220 jointly identify a sensing region 200 relative to the sensing measurement unit 205.
[0047] In some arrangements, the sensing measurement unit has the ability to measure multiple sensing regions. FIG. 3 is a 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 can be a BS or a UE, or another suitable device having the ability or requirement to detect multiple sensing regions 310, 320, and 330. Each of the sensing regions 310, 320, and 330 can be defined by a respective set of sensing parameters, in the manner described herein.
[0048] In some examples, the sensing measurement unit 305 sends the 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 method by which each sensing region is determined or identified can be the same or different. For example, the sensing region 310 can be determined by the sensing distance range, the sensing region 310 can be determined by the sensing distance range and the sensing degree range, and the sensing region 330 can be defined by location coordinates, such as Global Positioning System (GPS) longitude and latitude coordinates. Other methods of determining and identifying the sensing regions can be likewise implemented.
[0050] In some arrangements, due to differences in the capabilities of the sensing measurement units or business requirements, in the request message, the sensing measurement unit not only indicates the list of sensing regions it expects to detect, but also the priority of each sensing region. In some arrangements, of the plurality of sets of sensing parameters includes a priority level for each of the plurality of sensing regions.
[0051] For example, in the request from the sensing measurement unit 305 to the sensing control function includes a different priority level for each of the sensing regions 310, 320, and 330. The sensing region 310 is associated with a first priority level, sensing region 320 is associated with a second priority level, and sensing region 330 is associated with a third priority level.
[0052] The sensing region can be determined using any suitable methods described herein. The priority level describes the priority level of sensing measurements in a region. In some examples, there are six priority levels, identified by values or indices 0-5. In some examples, priority level 0 represents the lowest priority, while priority level 5 represents the highest priority. Priority level can be determined based on detection quality, perception area, business requirements, and so on. The sensing measurement unit prioritizes measurement of sensing reference signals in a sensing region with a higher priority.
[0053] In some arrangements, for different sensing regions, different bandwidths and period of sensing reference signals are specified. In some arrangements, each of the plurality of sets of sensing parameters includes a bandwidth and a period for the sensing reference signals for each of the plurality of sensing regions. A period of sensing refers to a period by which the sensing measurement unit measures a sensing reference signal within a sensing region. For example, in the request from the sensing measurement unit 305 to the sensing control function includes a different bandwidth and a period of sensing for each of the sensing regions 310, 320, and 330. The sensing region 310 is associated with a first bandwidth and a first period, the 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] Accordingly, the request message includes information for or defines at least one sensing region of the sensing measurement unit and for each sensing region, at least one of a priority level, bandwidth, and sensing period.
[0055] In some arrangements, the sensing control function configures the sensing region of the sensing measurement unit based on capabilities of the sensing measurement unit, measurement requests, network qualities, or other information. The sensing control function sends a response message to the sensing measurement unit in response to the request. The response carries a sensing parameter including at least one of a signal power (e.g., a range of signal powers) , a sensing distance (e.g., a range of sensing distances) , a sensing direction (e.g., a range of sensing directions) , or a sensing time (e.g., a range of sensing times) . In some examples, a range of signal powers is indicated using a threshold corresponding to a received power of a sensing reference signal to be measured, as described herein. In some examples, a range of sensing distances can be used to indicate a distance range of a sensing reference signal to be measured, as described herein. In some examples, the range of sensing directions is used to indicate a direction range of a sensing reference signal to be measured, as described herein. In some examples, the range of sensing times is used to indicate an expected time range for measuring a sensing reference signal, as described herein.
[0056] In some arrangements, the response sent and received at 130 and 140, respectively, includes one or more of the plurality of sensing regions, each of the one or more of the plurality of sensing regions is defined by at least one of a signal power of the sensing reference signals, a sensing distance of the sensing reference signals, a sensing direction of the sensing reference signals, or a sensing time of the sensing reference signals, wherein the sensing reference signals are sent within the plurality of sensing regions in response to receiving the response.
[0057] By using the sensing parameter in the response, a sensing region can be determined by the sensing measurement unit. Multiple sensing regions can be indicated in the response message, in a manner similar to those indicated in the request message. For example, the sensing control function configures the sensing measurement unit to detect two sensing regions, including a first sensing region and a second sensing region. The sensing regions can be defined by the sensing parameter in the response. For example, the response message includes a list of the sensing regions. Each sensing region is indicated by one or more of the range of signal powers, range of sensing distances, range of sensing directions, and range of sensing times.
[0058] Furthermore, due to differences in the capabilities of sensing measurement units and business requirements, the sensing control function in the response message can indicate a priority of each sensing region, as described herein in relation to the request. For example, in the response from the sensing control function to the sensing measurement unit includes a different priority level for each of the first and second sensing regions. The first sensing region is associated with a first priority level, the second sensing region is associated with a second priority level.
[0059] As noted herein in relation to the request, the priority level describes the priority level of sensing measurements in a region. In some examples, there are three priority levels, identified by values or indices 0-2. In some examples, priority level 0 represents the lowest priority, while priority level 2 represents the highest priority. Priority level can be determined based on detection quality, perception area, business requirements, and so on. The sensing measurement unit prioritizes measurement of sensing reference signals in a sensing region with a higher priority. In some examples, the request includes the plurality of sensing regions and a priority level for each of the plurality of sensing regions.
[0060] As noted herein in relation to the request, in some arrangements, for different sensing regions, different bandwidths and period of sensing reference signals are specified. As noted above, the period of sensing refers to a period by which the sensing measurement unit measures a sensing reference signal within a sensing region. For example, in the response from the sensing control function to the sensing measurement unit includes a different bandwidth and a period of sensing for each of the first and second sensing regions. The first sensing region is associated with a first bandwidth and a first period, and the second sensing region is associated with a second bandwidth and a second period. In some examples, the request includes the plurality of sensing regions and a bandwidth and a period for sensing the sensing reference signals for each of the plurality of sensing regions.
[0061] Accordingly, the response message includes information for or defines at least one sensing region of the sensing measurement unit and for each sensing region, at least one of a priority level, bandwidth, and sensing period.
[0062] In some arrangements, information can be exchanged in a monostatic sensing mode. A monostatic sensing mode refers to a device completing both the transmission and reception of sensing reference signals. In some arrangements, after the sensing measurement unit 102 sends the sensing reference signals within the plurality of sensing regions at 150, the sensing measurement unit 102 receives a reflected or scattered signal corresponding to the sensing reference signals and measures the reflected or scattered signal.
[0063] FIG. 4 is a diagram illustrating an example method 400 for performing sensing in a monostatic sensing mode, according to various arrangements. In a monostatic sensing mode, a sensing measurement unit 405 (e.g., a BS or a UE) sends a sensing reference signal 410 toward an environment 430 (e.g., the transmitting sensing region and the receiving sensing region of the sensing measurement unit 405) and receives the corresponding reflected or scattered waves or signals 420 that corresponding to the sensing reference signal 410, where the sensing reference signal 410 is reflected or scattered by the environment 430.
[0064] In some examples, a sensing measurement unit sends a measurement request, in which at least one sensing region is each defined or identified using the sensing parameter (e.g., the range of signal powers, the range of sensing distances, the range of sensing directions, or the range of sensing times) . In the examples in which the at least one sensing region includes a plurality of sensing regions, the request message can define or identify each of the plurality of sensing regions using the sensing parameter (e.g., the range of signal powers, the range of sensing distances, the range of sensing directions, or the range of sensing times) .
[0065] Furthermore, due to differences in the capabilities of sensing measurement units or business requirements, the sensing measurement unit indicates in the request message not only the list of sensing regions that the sensing measurement unit is configured to detect, but also one or more of a priority of each sensing region, a bandwidth, or a sensing period for sensing reference signals.
[0066] As noted herein in relation to the request, the priority level describes the priority level of sensing measurements in a region. In some examples, there are five priority levels, identified by values or indices 0-4. In some examples, priority level 0 represents the lowest priority, while priority level 4 represents the highest priority. Priority level can be determined based on detection quality, perception area, business requirements, and so on. The sensing measurement unit prioritizes measurement of sensing reference signals in a sensing region with a higher priority. As noted herein in relation to the request, in some arrangements, for different sensing regions, different bandwidths and period of sensing reference signals are specified.
[0067] In response to the sensing control function receiving a request from the 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 arrangements, in the measurement response message, the sensing control function can indicate 1) the sensing regions, 2) each sensing region and its measurement priority, 3) each sensing region and its measurement period and its time-frequency domain resources (e.g., bandwidth) , or 4) each sensing region and its measurement priority level, its measurement period, and its time-frequency domain resources.
[0069] FIG. 5 is a signaling diagram illustrating an example method 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 to the sensing measurement unit 502 a sensing measurement response (or response, response message) .
[0070] In some arrangements, information can be exchanged in a bistatic sensing mode. A bistatic sensing mode refers to a first device transmits the sensing reference signal and a second device receives the reflected or scattered signal. In some arrangements, a reflected or scattered signal corresponding to the sensing reference signals is received by another sensing measurement unit different form the sensing measurement unit 102. The another sensing measurement unit measures the reflected or scattered signal.
[0071] FIG. 6 is a diagram illustrating an example method 600 for performing sensing in a bistatic sensing mode, according to various arrangements. In a bistatic sensing mode, a sensing measurement unit 605a (e.g., a first BS or a first UE) sends a sensing reference signal 610 toward an environment 630, which is within a sensing region (e.g., the transmitting sensing region of the sensing measurement unit 605a and the receiving sensing region of the sensing measurement unit 605b) . The sensing measurement unit 605b (e.g., a second BS or a second UE) receives the corresponding reflected or scattered waves or signals 620 that corresponding to the sensing reference signal 610. The sensing reference signal 610 is reflected or scattered by the environment 630.
[0072] In one example, the sensing measurement unit 605a is a BS and the sensing measurement unit 605b is a UE. In one example, the sensing measurement unit 605a is a first BS and the sensing measurement unit 605b is a second BS. In one example, the sensing measurement unit 605a is a first UE and the sensing measurement unit 605b is a second UE. In one example, the sensing measurement unit 605a is a UE and the sensing measurement unit 605b is a BS.
[0073] In some examples, the sensing measurement unit 605a, which is the sender of the sensing reference signal 610, is a sensing transmitter. The sensing measurement unit 605b, which is the receiver of the reflected or scatted waves of signals 620, is a sensing receiver. In some examples in which the sensing measurement unit 605a and the sensing measurement unit 605b are BSs (e.g., a BS-sending-BS-receiving mode) , in one sensing transmission, a first BS is the sensing transmitter while a second BS is the sensing receiving. In another sensing transmission, the first BS is the sensing receiver and the second BS is the sensing transmitted. Thus, a sensing measurement unit, which can be either the sensing transmitter or receiver, can request for sending and receiving sensing measurements separately. In some examples, a sensing measurement unit can request the sensing transmission measurement configuration and sensing reception measurement configuration in one message or different messages. In some arrangements, the sensing measurement unit 102 sends to the sensing control function 104, and the sensing control function 104 receives from the sensing measurement unit 102 a first message requesting for sensing transmission measurement configuration. The sensing measurement unit 102 sends to the sensing control function 104, and the sensing control function 104 receives from the sensing measurement unit 102 a second message requesting for sensing reception measurement configuration. The first message and the second message are different messages or a same message.
[0074] For the configuration of sensing transmission measurement and sensing reception measurement, a sensing measurement unit sends a measurement request which includes at least one of a transmitting sensing region or a receiving sensing region. The transmitting sensing region and the receiving sensing region are respectively indicated by one or more of the sensing parameters (e.g., the range of signal powers, range of sensing distances, range of sensing directions, and range of sensing times) . In some arrangements, the request includes one or more of at least one transmitting sensing region or at least one receiving sensing region. 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 sensing parameter and the second sensing parameter includes at least one of a signal power of the sensing reference signals, a sensing distance of the sensing reference signals, a sensing direction of the sensing reference signals, or a sensing time of the sensing reference signals.
[0075] In some arrangements, multiple transmitting sensing regions and multiple receiving sensing regions can be indicated in the request message. For example, the sensing measurement unit requests detection of two transmitting sensing regions and two receiving sensing regions, and includes a list of these sensing regions in the request message.
[0076] In some arrangements, due to differences in the capabilities of sensing measurement units or business requirements, the sensing measurement unit in the request message indicates not only the list of sensing regions that the sensing measurement unit is configured to detect, but also one or more of a priority of each sensing region, a bandwidth, or a sensing period for sensing reference signals. In some arrangements, the request includes at least one of a priority level for each of the at least one transmitting sensing region or each of the at least one receiving sensing region, a bandwidth for each of the at least one transmitting sensing region or each of the at least one receiving sensing region, and a period for sensing the sensing reference signals for each of the at least one transmitting sensing region or each of the at least one receiving sensing region.
[0077] As noted herein in relation to the request, the priority level describes the priority level of sensing measurements in a region. In some examples, there are 2 priority levels, identified by values or indices 0-1. In some examples, priority level 0 represents the lowest priority, while priority level 1 represents the highest priority. Priority level can be determined based on detection quality, perception area, business requirements, and so on. The sensing measurement unit prioritizes measurement of sensing reference signals in a sensing region with a higher priority. As noted herein in relation to the request, in some arrangements, for different sensing regions, different bandwidths and period of sensing reference signals are specified.
[0078] When the sensing control function receives a request from the sensing measurement unit, the sensing control function configures the measurement of the sensing measurement unit based on the measurement request from the sensing measurement unit, the capacity of the sensing measurement unit, and the need for data fusion from multiple sensing measurement units.
[0079] In some arrangements, in the measurement response message, the sensing control function can indicate 1) the sensing regions, 2) each sensing region and its measurement priority, 3) each sensing region and its measurement period and its time-frequency domain resources (e.g., bandwidth) , or 4) each sensing region and its measurement priority level, its measurement period, and its time-frequency domain resources.
[0080] In some arrangements, the sensing measurement unit 605a includes a BS and the sensing measurement unit 605b includes a UE. The BS plans to measure five regions (e.g., sensing region 1 –5) based on the capabilities of the BS and business requirements. The BS indicates the desired sensing regions in the request message. Furthermore, the BS can indicate the priority of these sensing regions or the measurement configuration of these sensing regions (including the bandwidth of the sensing reference signal, period of the sensing reference signal, and so on) . Furthermore, the BS can indicate a combination of different types of information (e.g., sensing parameters) that can define, identify, or configure these sensing regions.
[0081] In some arrangements, the sensing measurement unit 102 includes a BS. A reflected or scattered signal corresponding to the sensing reference signals is received by another sensing measurement unit, which measures the reflected or scattered signal. The another sensing measurement unit includes a UE.
[0082] The sensing control function determines, based on the requests and business requirements of the BS or other information that, only four of the five sensing regions (e.g., sensing region 1 –4) needs to be measured by the BS. In the response message, the sensing control function indicates the information (e.g., the sensing parameter) of these four sensing regions. Furthermore, sensing control function can indicate at least one of the priority, bandwidth, or sensing period of each of these four sensing regions (e.g., sensing region 1 –4) .
[0083] A UE is connected to the BS and receives a message from the BS or the sensing control function that the BS will sensing the four sensing regions (e.g., the sensing region 1 –4) . The UE sends a response to the BS or the sensing control function, indicating that the UE can sense in sensing regions 1 and 2. The UE therefore becomes the sensing measurement unit 605b.
[0084] In some arrangements, the sensing control function configures detection parameters. In wireless sensing, given that the sensed object is not connected to the network, it is impossible to know whether there is a sensing target before sensing. Therefore, in sensing, whether an object exists is determined. However, due to the limited sensing range of a single device and the possibility of blind spots, wireless sensing utilizes the characteristics of mobile communication wide area coverage and numerous UEs. Multiple sensing measurement units can sensing and detect targets jointly in an environment. In order to integrate and process the sensing data of multiple sensing measurement units, the network defines parameters for handling received reflected or scattered signals in a unified manner.
[0085] In different application scenarios, humans, vehicles, UAVs, and buildings within the sensing region can be detected. Different UEs have different detection angles, accuracies, ranges, capabilities, and algorithms. When different UEs extract information from sensing reference signals, differences in information accuracy and detection thresholds can result.
[0086] FIG. 7 is a diagram illustrating 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) sends a sensing reference signal toward an environment 730, which is within a sensing region (e.g., the transmitting sensing region of the sensing measurement unit and the receiving sensing region of the sensing measurement units 705a, 705b, and 705c) . The sensing measurement units 705a, 705b, and 705c (e.g., a second BS or a second UE) receives the corresponding reflected or scattered waves or signals 620 that corresponding to the sensing reference signal. The sensing reference signal is reflected or scattered by the environment 730. In other words, the sensing measurement units 705a, 705b, and 705c are used to detect the same region. The sensing control function configures the detection thresholds of the sensing measurement units 705a, 705b, and 705c to control their processing of received reflected or scattered signals.
[0087] The sensing control function or a BS can send messages to each of the sensing measurement units 705a, 705b, and 705c indicating 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 region (e.g., corresponding to or enclosing the environment 730) .
[0088] In some arrangements, a detection threshold can used by a sensing measurement unit receiving the reflected or scattered signals to determine the presence of at least one object. In response to determining that a power of the reflected or scattered signals exceeds the detection threshold, the sensing measurement unit determines that an object exists.
[0089] In some arrangements, the sensing measurement unit 102 receives from the sensing control function 104, and the sensing control function 104 sends to the sensing measurement unit 102, measurement configuration for measuring a reflected or scattered signal corresponding to the sensing reference signals. The sensing control function 104 sends a respective measurement configuration to each of a plurality of sensing measurement units measuring the reflected or scattered signal. In some arrangements, the measurement configuration includes at least one of a detection threshold and the plurality of sensing region. The detection threshold defines a power threshold of the reflected or scattered signal that corresponds to a presence of at least one object.
[0090] In some examples, due to different perceptual distances, different detection thresholds are configured for different regions. Therefore, the sensing control function or the BS configures different sensing thresholds for UEs for detecting different sensing regions. The sensing control function or the BS indicates the measurement processing configuration information of the UE in the measurement configuration message.
[0091] In some arrangements, although the sensing measurement units 705a, 705b, and 705c are all detecting the same sensing region, due to the difference in the distance between the sensing measurement units 705a, 705b, and 705c and the sensing region, the powers of the reflected or scattered signal to the sensing measurement units 705a, 705b, and 705c are also different. In the examples in which the power differences are large, the sensing measurement units 705a, 705b, and 705c are not suitable for processing using the same detection threshold. Therefore, the sensing control function or the BS sets different detection thresholds of the sensing measurement units 705a, 705b, and 705c for the same sensing region in the measurement configuration message according to the quality of data fusion or other factors.
[0092] The sensing region is indicated in the measurement configuration message by one or more of the sensing parameters (e.g., the range of signal powers, range of sensing distances, range of sensing directions, and range of sensing times) as described herein.
[0093] Furthermore, the sensing control function or the BS can indicate the detection thresholds for multiple sensing areas respectively. For example, the sensing control function or the BS can indicate to a sensing measurement unit the detection thresholds of two sensing regions (such as a first sensing region and a second sensing region) . The sensing control function or the BS sends the measurement configuration message that carries the information on the two sensing regions and respective detection thresholds. That is, the measurement configuration message can identify the first sensing region and first corresponding detection threshold, the second sensing region and the second corresponding detection threshold.
[0094] The detection thresholds of different sensing regions may be the same or different. In some examples, the indication method of two sensing regions is described. When the UE supports more sensing regions, multiple sensing regions and detection thresholds can be carried as described.
[0095] In some arrangements, sensing regions can be configured implicitly. The sensing measurement unit can send some sensing measurement resource to sense the environment or targets. FIG. 8 is a diagram illustrating a sensing measurement unit 805 configured to for sensing using the beams 810-1, 810-2, 810-3, …, 810-n, according to various arrangements. The sensing measurement unit 805 (e.g., a sensing transmitter) sends n beams 810-1, 810-2, 810-3, …, 810-n for sensing measurement. Each of the beams 810-1, 810-2, 810-3, …, 810-n corresponds to a sensing direction of the antenna panel of the sensing measurement unit 805. Each of the beams 810-1, 810-2, 810-3, …, 810-n corresponds to a sensing measurement resource.
[0096] FIG. 9 is a signaling diagram illustrating an example method 900 for configuring sensing measurement resources, according to various arrangements. The sensing measurement unit 805 sends a sensing measurement resource message at 910 to a sensing control function 902. The sensing measurement resource message includes information of the sensing measurement resources that the sensing measurement unit 805 will send. At 920, the sensing control function 902 configures the sensing measurement resources that the sensing measurement unit 905 (e.g., a sensing receiver) needs to measure according to the sensing measurement resources of the sensing measurement unit 805. The sensing measurement unit 905 can further use the information of the measured target, and the information of the sensing measurement unit 905 by sending to the sensing measurement unit 905 the sensing measurement resource configuration 920. The information of the measured target is based on the previous measurement process. In some examples, the sensing measurement unit 805 informs the sensing control function 902 of the sensing measurement resources corresponding to the n beams 810-1, 810-2, 810-3, …, 810-n, and the sensing control function 902 configures the measurement resources of the sensing measurement unit 905 to indicate that the sensing measurement unit 905 only needs to measure the sensing resources corresponding to a subset of the beams, e.g., the beams 810b and 810c.
[0097] In some examples, the sensing measurement unit 102 sends to the sensing control function 104 and the sensing control function 104 receives from the sensing measurement unit 102, a sensing measurement resource message including at least one sensing resource. The sensing control function sends to another sensing measurement unit a sensing measurement resource configuration including one or more of the at least one sensing resource. The sensing measurement unit is a sensing transmitter, and the another sensing measurement unit is a sensing receiver. In some examples, the one or more of the at least one sensing resource sent by the sensing control function 104 to the another sensing measurement unit is a subset of the at least one sensing resource received by the sensing control function 104 from the sensing measurement unit 102.
[0098] In some examples, the sensing measurement unit 102 sends to the another sensing measurement unit and the another sensing measurement unit receives from the sensing measurement unit 102, sensing measurement resource configuration including one or more of the at least one sensing resource. The sensing measurement unit is a sensing transmitter, and the another sensing measurement unit is a sensing receiver.
[0099] Conventionally, a sensing measurement unit such as a UE usually selects the best measurement resource for measurement. However, in the sensing process, the coverage of different beams is different. The measured target may not be within the coverage range of the strongest beam. If measurement feedback is given according to the strongest beam, the information measured by the sensing measurement unit will not include the sensing target, resulting in missed detection.
[0100] In the arrangements disclosed herein, the sensing control function configures the sensing resources that each sensing measurement unit needs to measure and optimizes the measurement process of the sensing measurement unit through network configuration to improve measurement efficiency and accuracy.
[0101] In some arrangements, the n beams 810-1, 810-2, 810-3, …, 810-n sent by the sensing measurement unit 805 (sensing transmitter) are aimed at multiple sensing measurement units 905, and the sensing measurement unit 805 indicates to each sensing measurement unit 905 (sensing receiver) the sensing resources each sensing measurement unit 905 needs to measure. The sensing measurement resources that the sensing measurement unit 805 configures for sensing measurement unit 905 UE to be measured are a subset of the sensing measurement resources sent by the sensing measurement unit 805. FIG. 10 is a signaling diagram illustrating an example method 1000 for configuring sensing resources, according to various arrangements. At 1010, the sensing measurement unit 805 sends to the sensing measurement unit 905 the sensing measurement resource configuration 1010, including sensing resources that each sensing measurement unit 905 needs to measure within a sensing region. The sensing measurement unit 905 measures the reflected or scatter signals using the sensing resoruces, and reports the measurement results to the sensing measurement unit 805 and / or the sensing control function.
[0102] Similarly, if the sensing measurement unit 805 (sensing transmitter) sends n beams 810-1, 810-2, 810-3, …, 810-n for sensing measurement, and the sensing measurement unit 905 (sensing receiver) receives and measures the 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 to the sensing measurement unit 905. The sensing measurement resources that the sensing control function configures to the sensing measurement unit 905 to be measured are a subset of the sensing measuring resources sent by the sensing measurement unit 805.
[0103] In some arrangements, sensing measurement paths can be configured. Transmission of the SL PRS can be communicated via multiple transmission paths, including a Line Of Sight (LOS) path and Non-Line-Of-Sight (NLOS) paths which are reflected by other objects (such as walls) . Multiple paths arrive at the receiver at different times. Existing positioning measurements are usually based on a first path. However, in sensing, the first path may not be the path reflected or scattered by the measured target, and the first path may be the surrounding environment. In addition, there may be multiple measured targets, and the distance between each measured target and the sensing receiver is different, resulting in different times for paths passing through multiple measured targets to reach the sensing receiver. Therefore, in sensing, obtain the measurement information of only the first path is inaccurate. Feedback for all the measured information may not need to be provided because week signals are not helpful for sensing. On the other hand, too much feedback information over burdens the transmission.
[0104] In some arrangements, one sensing measurement unit is a sensing transmitter, and another sensing measurement unit is a sensing receiver. The network (the sensing control function or the BS) configures the sensing measurement feedback using a sensing measurement feedback configuration. In the sensing measurement feedback configuration, at least measurement threshold is included. The measurement threshold can be a measured signal strength (e.g., a range of Reference Signal Received Power (RSRP) ) , a distance (e.g., a range of distances) , a Doppler value (e.g., a range of Doppler values) , or a combination of these measurement thresholds. The Doppler threshold is a threshold for frequency offset due to the Doppler Effect. The range can be defined by a minimum value, or a maximum value, or a combination of minimum and maximum values. For example, the measurement threshold for network configuration is a RSRP threshold. When the measurement threshold indicates the minimum value of RSRP threshold, the second sensing measurement unit measures the reflected or scattered path exceeding RSRP and provide feedback of the same. If the measurement threshold can be a combination of multiple thresholds, such as indicating both RSRP threshold and distance threshold, the second sensing measurement unit measures a path that satisfies both threshold and provide feedback of the same. The network (e.g., the sensing control function) can indicate to measure a number (e.g., top N) reflected or scattered paths.
[0105] In some examples, the sensing measurement unit 102 receives from the sensing control function 104 and the sensing control function 104 sends to the sensing measurement unit 102, sensing measurement feedback configuration including a measurement threshold. The measurement threshold includes at least one of a signal strength threshold, a distance threshold, a Doppler threshold. In some examples, the sensing measurement unit 102 sends to the sensing control function 104 and the sensing control function 104 receives from the sensing measurement unit 102, feedback for the reflected or scattered signal corresponding to the sensing reference signals according to the sensing measurement feedback configuration.
[0106] FIG. 11 illustrates a block diagram of an example BS 1100 and an example UE 1120, according to various arrangements. The BS 1100 is a network node such as an evolved node B (eNB) , g Node B (gNB) , a femto station, a pico station, Reconfigurable Intelligent Surface (RIS) , relay node, Integrated Access and Backhaul (IAB) node, Network Controlled Repeater (NCR) node, and so on. The BS 1100 includes a transceiver module 1110, an antenna 1112, a processor module 1114, a memory module 1116, and a network communication module 1118, each module being coupled and interconnected with one another as necessary via a data communication bus 1111. The 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 one another as necessary via a data communication bus 1140. The BS 1100 communicates with the UE 1120 via a communication channel, link, connection, or beam, which can be any wireless channel or other medium suitable for transmission of data as described herein.
[0107] As would be understood by persons of ordinary skill in the art, the BS 1100 and the UE 1120 can further include any number of modules other than the modules shown in FIG. 11. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the implementations disclosed herein may 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 described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software can depend upon the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a suitable manner for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure.
[0108] In accordance with some implementations, the transceiver 1130 can be referred to herein as an uplink transceiver 1130 that includes a radio frequency (RF) transmitter and a RF receiver each including circuitry that is coupled to the antenna 1132. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in time duplex fashion. Similarly, in accordance with some implementations, the transceiver 1110 may be referred to herein as a downlink transceiver 1110 that includes a RF transmitter and a RF receiver each including circuity that is coupled to the antenna 1112. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 1112 in time duplex fashion. The operations of the two transceiver modules 1110 and 1130 can be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 1132 for reception of transmissions over the wireless transmission link at the same time that the downlink transmitter is coupled to the downlink antenna 1112. In some implementations, there is close time synchronization with a minimal guard time between changes in duplex direction.
[0109] The transceiver 1130 and the transceiver 1110 are configured to communicate via the wireless data communication link (e.g., channels, connections, and beams) , and cooperate with a suitably configured RF antenna arrangement 1112 / 1132 that can support a particular wireless communication protocol and modulation scheme. In some illustrative implementations, the transceiver 1110 and the transceiver 1130 are configured to support industry standards such as the Long Term Evolution (LTE) and emerging 5G / 6G standards, and the like. It is understood, however, that the present disclosure is not necessarily limited in application to a particular standard and associated protocols. Rather, the transceiver 1130 and the transceiver 1110 may be configured to support alternate, or additional, wireless data communication protocols, including future standards or variations thereof.
[0110] In some implementations, the UE 1120 can be various types of message clients such as a mobile phone, a smart phone, a personal digital assistant (PDA) , tablet, laptop computer, wearable computing device, etc. The processor modules 1114 and 1136 may be implemented, or realized, with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a 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 manner, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, or the like. A processor may also be implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.
[0111] Furthermore, the steps of a method or algorithm described in connection with the implementations disclosed herein may be implemented directly in hardware, in firmware, in a software module executed by processor modules 1114 and 1136, respectively, or in any practical combination thereof. The memory modules 1116 and 1134 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 1116 and 1134 may be coupled to the processor modules 1110 and 1130, respectively, such that the processors modules 1110 and 1130 can read information from, and write information to, memory modules 1116 and 1134, respectively. The memory modules 1116 and 1134 may also be integrated into their respective processor modules 1110 and 1130. In some implementations, the memory modules 1116 and 1134 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions to be 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 the processor modules 1110 and 1130, respectively.
[0112] The network communication module 1118 generally represents the hardware, software, firmware, processing logic, and / or other components of the BS 1100 that enable bi-directional communication between transceiver 1110 and other network components and communication nodes (e.g., another node such as the BS 1100 ) configured to communicate with the BS 1100 . For example, network communication module 1118 may be configured to support internet or WiMAX traffic. In a typical deployment, without limitation, network communication module 1118 provides an 802.3 Ethernet interface such that transceiver 1110 can communicate with a conventional Ethernet based computer network. In this manner, the network communication module 1118 may include a physical interface for connection to the computer network (e.g., Mobile Switching Center (MSC) ) . The terms “configured for, ” “configured to” and conjugations thereof, as used herein with respect to a specified operation or function, refer to a device, component, circuit, structure, machine, signal, etc., that is physically constructed, programmed, formatted and / or arranged to perform the specified operation or function.
[0113] While various arrangements of the present solution have been described above, it should be understood that they have been presented by way of example only, and not by way of limitation. Likewise, the various diagrams may depict an example architectural or configuration, which are provided to enable persons of ordinary skill in the art to understand example features and functions of the present solution. Such persons would understand, however, that the solution is not restricted to the illustrated example architectures or configurations, but can be implemented using a variety of alternative architectures and configurations. Additionally, as would be understood by persons of ordinary skill in the art, one or more features of some arrangements can be combined with one or more features of another arrangement described herein. Thus, the breadth and scope of the present disclosure should not be limited by any of the above-described illustrative arrangements.
[0114] It is also understood that any reference to an element herein using a designation such as “first, ” “second, ” and so forth does not generally limit the quantity or order of those elements. Rather, these designations can be used herein as a convenient means of distinguishing between two or more elements or instances of an element. Thus, a reference to first and second elements does not mean that only two elements can be employed, or that the first element must precede the second element in some manner.
[0115] Additionally, a person having ordinary skill in the art would understand that information and signals can be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits and symbols, for example, which may be referenced in the above description can be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0116] A person of ordinary skill in the art would further appreciate that any of the various illustrative logical blocks, modules, processors, means, circuits, methods and functions described in connection with the aspects disclosed herein can be implemented by electronic hardware (e.g., a digital implementation, an analog implementation, or a combination of the two) , firmware, various forms of program or design code incorporating instructions (which can be referred to herein, for convenience, as “software” or a “software module) , or any combination of these techniques. 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 techniques, depends upon the particular application and design constraints imposed on the overall system. Skilled artisans can implement the described functionality in various ways for each particular application, but such implementation decisions do not cause a departure from the scope of the present disclosure.
[0117] Furthermore, a person of ordinary skill in the art would understand that various illustrative logical blocks, modules, devices, components and circuits described herein can be implemented within or performed by an integrated circuit (IC) that can include a general purpose processor, a digital signal processor (DSP) , an application specific integrated circuit (ASIC) , a field programmable gate array (FPGA) or other programmable logic device, or any combination thereof. The logical blocks, modules, and circuits can further include antennas and / or transceivers to communicate with various components within the network or within the device. A general purpose processor can be a microprocessor, but in the alternative, the processor can be any conventional processor, controller, or state machine. A processor can also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other suitable configuration to perform the functions described herein.
[0118] If implemented in software, the functions can be stored as one or more instructions or code on a computer-readable medium. Thus, the steps of a method or algorithm disclosed herein can be implemented as software stored on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that can be enabled to transfer a computer program or code from one place to another. A storage media can be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store desired program code in the form of instructions or data structures and that can be accessed by a computer.
[0119] In this document, the term “module” as used herein, refers to software, firmware, hardware, and any combination of these elements for performing the associated functions described herein. Additionally, for purpose of discussion, the various modules are described as discrete modules; however, as would be apparent to one of ordinary skill in the art, two or more modules may be combined to form a single module that performs the associated functions according arrangements of the present solution.
[0120] Additionally, memory or other storage, as well as communication components, may be employed in arrangements of the present solution. It will be appreciated that, for clarity purposes, the above description has described arrangements of the present solution with reference to different functional units and processors. However, it will be apparent that any suitable distribution of functionality between different functional units, processing logic elements or domains may be used without detracting from the present solution. For example, functionality illustrated to be performed by separate processing logic elements, or controllers, may be performed by the same processing logic element, or controller. Hence, references to specific functional units are only references to a suitable means for providing the described functionality, rather than indicative of a strict logical or physical structure or organization.
[0121] Various modifications to the implementations described in this disclosure will be readily apparent to those skilled in the art, and the general principles defined herein can be applied to other implementations without departing from the scope of this disclosure. Thus, the disclosure is not intended to be limited to the implementations shown herein, but is to be accorded the widest scope consistent with the novel features and principles disclosed herein, as recited in the claims below.
