[0022] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0023] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to Radio Frequency (RF) signal (e.g., UWB signal) detection in mobile communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0024] It should be noted that RF signal detection may refer to a set of procedures performed by a User Equipment (UE) and / or a network node to manage the allocation, monitoring, sensing and / or measuring signal strength or signal quality (e.g., Reference Signal Received Power (RSRP) , Reference Signal Received Quality (RSRQ) , Signal to Interference Noise Ratio (SINR) , etc. ) of RF signals emitted by a wireless apparatus (e.g., an Ultra-wideband (UWB) detection apparatus, a Frequency Modulated Continuous Wave (FMCW) radar, a Continuous Wave (CW) radar, etc. ) that co-existed on the same or adjacent frequency bands of the UE.
[0025] FIG. 1 is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. Scenario 100 involves at least one network node and a UE, which may be a part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network) . Scenario 100 illustrates the current network framework. The UE may connect to the network side. The network side may comprise one or more network nodes. For illustrative purposes, one network node and one UE may be described hereinafter. However, it is not intended to limit the network scenarios of the present disclosure. In the present disclosure, a plurality of uplink transmission procedures may be implemented in the UE to minimize interference on the wireless communication network (e.g., 6G) and prevent degradation of the UWB system's performance on UWB channels (e.g., popular UWB channels such as channels 5 and 9 of band group 2 of the UWB system) . However, the UWB system is illustrated as an example; the present disclosure is not limited to the coexistence of the UWB systems and cellular mobile telecommunication.
[0026] In some implementations of the present disclosure, the UE may perform a detection before transmission. The detection may be sensing or measuring any RF signals of a wireless apparatus at an active frequency bandwidth of the UE. In one example, the wireless apparatus may be a UWB device. In one example, the wireless apparatus may be a CW radar, an FMCW radar, etc. In one example, the detection may be a UWB signal detection (e.g., time domain energy detection of the UWB signal) to determine the existence of a UWB signal, and the UE may determine that the UWB signal exists in an event that measured signal strength is greater than a specified / pre-determined level (e.g., X dBm) . In one example, the active frequency bandwidth may be a configured frequency bandwidth or a configured Bandwidth Part (BWP) . In another example, the active frequency bandwidth may be a scheduled bandwidth, and the detection may comprise sensing or measuring any RF signals at the scheduled bandwidth within the configured frequency bandwidth / BWP.
[0027] In some implementations, the network node may configure or schedule a sensing gap for the UWB signal detection to the UE. The UE may perform the detection within the sensing gap. The UE may determine not to transmit signals within the sensing gap of the uplink transmission. In other words, each UE in the network node may remain silent (i.e., doesn’ t transmit anything) within the sensing gap to avoid any interference on the detection. In some implementations, the network node may configure a bandwidth configuration for the uplink transmission. In one example, the bandwidth configuration may include a first frequency bandwidth / BWP. The UE may perform the UWB signal detection at the first frequency bandwidth / BWP within the sensing gap of the uplink transmission and may determine whether to transmit one or more uplink transmission units of the uplink transmission at the first frequency bandwidth / BWP based on the detection. In some implementations, the UE may perform the detection of the UWB signal at the first frequency bandwidth / BWP within the sensing gap in an event that the uplink transmission is scheduled by the network node. In some implementations, the UE may not perform the detection of the UWB signal at the first frequency bandwidth / BWP within the sensing gap in an event that there is no uplink transmission scheduled by the network node.
[0028] In some implementations, the UE may communicate with the network node based on the detection. In one example, the UE may determine whether to perform a transmission based on the detection. In one example, the UE may determine to reduce transmission power based on the detection, and then the interference impact on the UWB channel of the wireless apparatus may be reduced or minimized. In one example, the UE may determine to perform part of the transmission based on the detection. In one example, the UE may transmit a first part of the transmission allocated at a first frequency bandwidth, and not transmit a second part of the transmission allocated at a second frequency bandwidth in an event that the interference level of the detection is between a first threshold and a second threshold (e.g., greater than the first threshold and less than the second threshold) . The frequency bandwidth of the transmission is reduced compared to transmitting both the first and second parts of the transmission. The interference impacts on the UWB channel of the UWB device may be reduced or mitigated. Accordingly, the interference may be reduced for the UWB device and / or the UE. In one example, the UE may determine whether to retransmit based on the detection. In one example, the UE may determine whether to repeat a transmission within the same scheduling. In some implementations, the network node may configure sensing information (e.g., length of the sensing gap, specified interference level (s) , etc. ) or schedule an uplink transmission for the detection via a higher-layer signaling (e.g., System Information Block (SIB) , UE-specific Radio Resource Control (RRC) signaling) or layer 1 (L1) signaling (e.g., Downlink Control Information (DCI) ) . The UE may receive the information and perform the detection based on the sensing information.
[0029] In some implementations, to avoid serious interference from the RF signals (e.g., the UWB signals) on the downlink transmission channel of the UE, the UE may perform a grant-free uplink transmission. In one example, the UE may perform the grant-free uplink transmission without detection (e.g., without detecting the UWB signal) . In one example, the UE may perform the grant-free uplink transmission based on the detection. In one example, the UE may perform an uplink transmission without detection of the UWB signal in an event that the allocated frequency bandwidth for the uplink transmission is not greater than or less than a specified level, and perform the uplink transmission with detection of the UWB signal in an event that the allocated frequency bandwidth is greater than the specified level. In one example, the network node may configure the above conditions (e.g., specified level (s) , with / without detection, allocated frequency bandwidth (s) , etc. ) by a higher-layer signaling (e.g., SIB or UE-specific RRC signaling) or an L1 signaling.
[0030] In some implementations, uplink (UL) Non-Orthogonal Multiple Access (NOMA) may be applied, the UE may transmit a signal at the same frequency resources and time with different power and / or code to avoid interference. In some implementations, the uplink transmission may be changed based on the UWB signal detection. To reduce the burden of blind decoding from the network node, partial scheduling information about packet transmission may be indicated by the UE to help the network node decode the packet. In one example, the UE may indicate which packets are not transmitted through the partial scheduling information.
[0031] In some implementations, the UE may perform the uplink transmission based on the UWB signal detection in an event that the uplink transmission is scheduled with a grant. In one example, the UE may perform the uplink transmission without detecting the UWB signal in an event that the uplink transmission is not scheduled with a grant.
[0032] In some implementations, the UE may perform the uplink transmission without detecting the UWB signal in an event that the uplink transmission only includes Uplink Control Information (UCI) or the uplink transmission requires a small amount of uplink data transmission. In one example, the UE may perform the uplink transmission based on the UWB signal detection in an event that the uplink transmission requires a large amount of uplink data transmission.
[0033] In some implementations, the interference in some scenarios from the UWB system to the UE is small or insignificant; therefore, a specific handling procedure or UWB signal detection to reduce the interference may not be required. In one example, the UE may perform the uplink transmission without detecting the UWB signal in an event that the network is outdoors. In one example, the UE may perform the uplink transmission without detecting the UWB signal in an event that the UE is at the cell center. In one example, the UE may perform the uplink transmission without detecting the UWB signal in an event that the scheduled bandwidth of the UE is smaller than or not larger than a specified level. In one example, the UE may perform the uplink transmission without detecting the UWB signal in an event that the transmission power of the UE is smaller than or not larger than a specified level. In one example, the network node may configure the above conditions (e.g., scenarios, specified level, with / without detection, allocated frequency bandwidth, etc. ) by a higher-layer signaling (e.g., SIB or UE-specific RRC signaling) or an L1 signaling (e.g., DCI) . In one example, the UE and / or the network node may determine the above conditions based on a timing advance or a signal strength.
[0034] In some implementations, the UE may determine whether to perform periodic uplink (e.g., Periodic Sounding Reference Signal (P-SRS) ) signal transmission. In one example, the UE may determine that no periodic uplink is transmitted (i.e., the UE may not enable the periodic uplink transmission, and the uplink transmission may be triggered by the network node) on those channels / bands overlapped with the UWB channels. In one example, the UE may perform the periodic uplink transmission after the UWB signal detection. In one example, the UE may perform the periodic uplink transmission without the UWB signal detection, wherein the transmission signal of the periodic uplink transmission may be designed to occupy a short duration (e.g., 1 symbol) and to transmit on a narrow band; thus, the performance impact on the UWB system may be small.
[0035] In some implementations, the downlink carrier of the UE may be used with a guard band in an event that the downlink carrier is transmitted on adjacent channels (e.g., channels 6, 8, 10 of band group 2 of the UWB system) of the popular UWB channels. In some implementations, the UE may perform the uplink transmission only on non-popular UWB channels to prevent introducing interference to the UWB system.
[0036] FIG. 2A is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. In some implementations, as illustrated in FIG. 2A, the sensing gap may be configured or scheduled at the first N uplink symbol (s) per M uplink unit (s) within an uplink transmission. The length of an uplink transmission unit and the length of the uplink unit may be one symbol (e.g., one Orthogonal Frequency Division Multiplexing (OFDM) symbol) . The length of an uplink transmission unit and the length of the uplink unit may be a fixed number of symbol (s) . The length of the uplink transmission may be M symbol (s) or M times the fixed number symbol (s) . The length of the sensing gap may be N symbol (s) or N times the fixed number symbol (s) . The uplink transmission may include P uplink transmission unit (s) , wherein P may be a subtraction difference M-N. The uplink transmission unit may carry uplink data, DeModulation Reference Signal (DMRS) , or may be a unit of UCI. The uplink unit may be a Physical Uplink Shared Channel (PUSCH) unit, a Physical Uplink Control Channel (PUCCH) unit, a unit of the sensing gap, or a unit of UCI. The uplink transmission unit may carry a Code Block Group (CBG) index, a Code Block (CB) index, or a Transport Block (TB) index. The uplink transmission unit may be a PUSCH transmission unit or a PUCCH transmission unit. In one example, the uplink transmission unit may be a CBG, a CB, or a TB. In one example, the uplink transmission unit may be a fixed number of CBG (s) , CB (s) , or TB (s) . In one example, the UE may determine whether to detect the UWB signal within the sensing gap based on an indication of a sensing configuration, wherein the indication indicates whether to enable the detection. N, M, and P are natural numbers and may be configured by a higher-layer signaling (e.g., SIB or UE-specific RRC signaling) or an L1 signaling (e.g., DCI) . In one example not illustrated in FIG. 2A, there may be a processing gap between the sensing gap and the uplink transmission unit (s) for the UE to determine whether to transmit the uplink transmission unit (s) . In one example, the sensing gap, N, M, P, the processing gap, the CBG index, the CB index, and / or the indication may be configured in a sensing configuration or in DCI, or the network node may schedule the sensing gap, N, M, P, the processing gap, the CBG index, the CB index, and / or the indication.
[0037] FIG. 2B is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. In some implementations, as illustrated in FIG. 2B, the sensing gap is configured or scheduled at the first uplink symbol of each uplink transmission, two uplink transmissions are scheduled or configured, and each uplink transmission includes 13 uplink transmission units. Each code block group, CBG #1 and CBG #2, may include 13 uplink transmission units. During the first uplink transmission, the UE detects that the UWB signal detection exists (e.g., an interference level (IL) of the UWB signal detection is greater than a first threshold) within the sensing gap. Then the UE determines not to transmit CBG #1 accordingly. The UE may be required to retransmit CBG #1. During the second uplink transmission, the UE detects that the UWB signal detection does not exist (e.g., the interference level (IL) of the UWB signal detection is not greater than the first threshold) within the sensing gap. Then the UE may transmit CBG #2 accordingly. In one example, the first threshold X may be configured in the sensing configuration or DCI, or the network node may schedule the first threshold X. In one example, the UE may transmit CBG #2 in an event that the amount of CBG #2 is smaller than a predetermined level. In some implementations, the UE may retransmit CBG #1 in the next scheduling. In some implementations, the uplink transmission (e.g., the PUSCH transmission) may carry an explicit CBG index, and the UE may delay CBG #1 to the following available resource.
[0038] FIG. 2C is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. In some implementations, as illustrated in FIG. 2C, the sensing gap is configured or scheduled at the first two uplink symbols of each uplink transmission, two uplink transmissions are scheduled or configured, and each uplink transmission includes 12 uplink transmission units. Each of the code block groups CBG #1, CBG #2, CBG #3, and CBG #4 includes six uplink transmission units. During the first uplink transmission, the UE detects that the UWB signal detection exists (e.g., an interference level (IL) of the UWB signal detection is greater than a first threshold) within the sensing gap. Then the UE determines not to transmit all code block groups CBG #1 and CBG #2 accordingly. During the second uplink transmission, the UE detects that the UWB signal does not exist (e.g., the interference level (IL) of the UWB signal detection is not greater than the first threshold) within the sensing gap. Then the UE may transmit all code block groups CBG #3 and CBG #4 accordingly.
[0039] FIG. 2D is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. In some implementations, the UE may determine whether to transmit part of or all the uplink transmission after the UWB signal detection. In some implementations, the UE may determine the uplink transmission based on the interference level of the UWB signal detection. In one example, the UE may transmit a first part of the transmission, and not to transmit a second part of the transmission in an event that an interference level of the detection is between a first threshold and a second threshold (e.g., greater than the first threshold and less than the second threshold) . The amount of the first part of the uplink transmission is relatively small compared to transmitting the whole uplink transmission. Thus, the interference impacts on the UWB channel of the UWB device may be reduced or mitigated. In one example, the first and second parts of the uplink transmission are scheduled or configured at different frequency bandwidths. In one example, the first and second parts of the uplink transmission are scheduled or placed on a first frequency bandwidth and a second frequency bandwidth, respectively; the first and second frequency bandwidths may be the same or different. In one example, the first frequency bandwidth may be a first configured bandwidth in the first active BWP, and the second frequency bandwidth may be a second configured bandwidth in the second active BWP. The first and second active BWPs may be the same or different. In another example, the first and second frequency bandwidths may be configured as a first BWP and a second BWP. In another example, the first and second frequency bandwidths may be a first scheduled bandwidth in a first BWP and a second scheduled bandwidth in a second BWP, respectively; however, the present disclosure is not limited thereto. The UE may transmit the first part of the transmission allocated at the first frequency bandwidth (or at the first BWP) and not transmit the second part of the transmission allocated at a second frequency bandwidth (or at the second BWP) in an event that the interference level of the detection is between a first threshold and a second threshold. In one example, the first frequency bandwidth (or the first BWP) is smaller than the second frequency bandwidth (or the second BWP) . In one example, the second frequency bandwidth (or the second BWP) may be allocated more adjacent to the frequency bandwidth used by the UWB device. Thus, the interference impacts on the UWB channel of the UWB device may be reduced or mitigated through implementing any of the above design options.
[0040] In some implementations, as illustrated in FIG. 2D, the sensing gap is configured or scheduled at the first two uplink symbols of the uplink transmission, and two uplink transmissions are scheduled or configured. Each of the code block groups CBG #1, CBG #2, CBG #3, and CBG #4 may include one or more uplink transmission units. During the first uplink transmission, the UE detects that an interference level (IL) of the UWB signal detection is between a first threshold X and a second threshold Y. Then the UE transmits a first part of the uplink transmission units (i.e., CBG #1) , and not to transmit a second part of the uplink transmission units (i.e., CBG #2) accordingly. During the second uplink transmission, the UE detects that the interference level (IL) of the UWB signal detection is not greater than the first threshold X. Then the UE may transmit all code block groups CBG #3 and CBG #4 accordingly. In one example, the first threshold X and the second threshold Y may be configured in the sensing configuration or DCI, or the network node may schedule the first threshold X and the second threshold Y. In one example, the size of CBG #2 is much larger than that of CBG #1. In one example, the frequency bandwidth for transmitting CBG #2 is much broader than the frequency bandwidth for transmitting CBG #1. Only transmitting CBG #1 requires a smaller size of the code block group or a smaller frequency bandwidth. Thus, the interference impacts on the UWB channel of the UWB device may be reduced or mitigated.
[0041] FIG. 2E is a diagram depicting example scenarios under schemes in accordance with implementations of the present disclosure. In some implementations, as illustrated in FIG. 2E, the uplink transmission (e.g., PUSCH transmission) with repetitions may be used to increase the occasions for transmission. The scheduled or configured uplink transmission format of REP #1 is the same as that in FIG. 2A for brief illustration. However, the present disclosure is not limited thereto. Additionally, there may be a gap between REP #1 and REP #2 (That is, there is no overlap between REP #1 and REP #2) . REP #2 is the same as REP #1 (same uplink transmission format) , therefore, the UE may determine the transmission of CBG #1 within two separate sensing gaps. The repetitions may help the UE to transmit CBG #1 in an event that the UWB signal is not detected within any of the sensing gaps. Illustrative Implementations
[0042] FIG. 3 illustrates an example communication system 300 having an example communication apparatus 310 and an example network apparatus 320 in accordance with an implementation of the present disclosure.

[0043] Communication apparatus 310 may be a part of an electronic apparatus, which may be a UE such as a portable or mobile apparatus, a wearable apparatus, a wireless communication apparatus or a computing apparatus. For instance, communication apparatus 310 may be implemented in a smartphone, a smartwatch, a personal digital assistant, a digital camera, or a computing equipment such as a tablet computer, a laptop computer or a notebook computer. Communication apparatus 310 may also be a part of a machine type apparatus, which may be an IoT, NB-IoT, or IIoT apparatus such as an immobile or a stationary apparatus, a home apparatus, a wire communication apparatus or a computing apparatus.

Communication apparatus 310 may further include one or more other components not pertinent to the proposed scheme of the present disclosure (e.g., internal power supply, display device and / or user interface device) , and, thus, such component (s) of communication apparatus 310 are neither shown in FIG. 3 nor described below in the interest of simplicity and brevity.
[0044] Network apparatus 320 may be a part of a network apparatus, which may be a network node such as a satellite, a base station, a small cell, a router or a gateway.

Network apparatus 320 may further include one or more other components not pertinent to the proposed scheme of the present disclosure (e.g., internal power supply, display device and / or user interface device) , and, thus, such component (s) of network apparatus 320 are neither shown in FIG. 3 nor described below in the interest of simplicity and brevity.
[0045] In one aspect, each of processor 312 and processor 322 may be implemented in the form of one or more single-core processors, one or more multi-core processors, or one or more CISC processors. That is, even though a singular term “a processor” is used herein to refer to processor 312 and processor 322, each of processor 312 and processor 322 may include multiple processors in some implementations and a single processor in other implementations in accordance with the present disclosure. In another aspect, each of processor 312 and processor 322 may be implemented in the form of hardware (and, optionally, firmware) with electronic components including, for example and without limitation, one or more transistors, one or more diodes, one or more capacitors, one or more resistors, one or more inductors, one or more memristors and / or one or more varactors that are configured and arranged to achieve specific purposes in accordance with the present disclosure. In other words, in at least some implementations, each of processor 312 and processor 322 is a special-purpose machine specifically designed, arranged and configured to perform specific tasks including UWB signal detection in a device (e.g., as represented by communication apparatus 310) and a network (e.g., as represented by network apparatus 320) in accordance with various implementations of the present disclosure.
[0046] In some implementations, communication apparatus 310 may also include a transceiver 316 coupled to processor 312 and capable of wirelessly transmitting and receiving data. In other words, processor 312 may transceive the data such as configuration, message, signal, information, indicator, etc. via transceiver 316. Transceiver 316 may include an MR and an LR.

[0063] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0064] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application.
