BACKGROUND TECHNICAL FIELD

[0001] The present disclosure relates generally to communication systems, and more specifically to wireless devices configured to implement power control for wireless sensing.

[0002] INTRODUCTION

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0004] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is a continuing

[0006] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

[0007] In one aspect, the disclosure provides a method of wireless communication at a user equipment (UE).

[0025] DETAILED DESCRIPTION

[0026] The detailed description set forth below, in connection with the appended drawings and embodiments described herinin, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein can be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without

[0027] Recent improvements in wireless communications have introduced wireless communication systems that utilize radio access technologies that operate in higher frequencies (e.g., millimeter wave, terahertz (THz), low THz bands, 30-300 GHz frequency range, etc.). In addition to providing high rates of communication, wireless components configured to operate in higher frequencies can also provide high resolution sensing capabilities. However, employing communication components for wireless sensing within a communication system can interfere with data transmissions at other wireless devices within the communication system. For example, radar signals transmitted during wireless sensing activities by a user equipment can interfere with wireless communications to and from neighboring user equipment devices. As used herein, “wireless sensing” can refer to employing reflected waveforms and signal processing to detect, predict, or measure. In some aspects, machine learning systems can be employed in wireless sensing techniques. For example, raw data corresponding to reflected signals can be converted into a fast Fourier transform (FFT). Further, one or more regression techniques, classification techniques, or other artificial intelligence techniques can be applied to the FFT to perform wireless sensing actions.

[0028] In one aspect, the present disclosure addresses the above-described interference problem by providing a sensing management procedure in which a UE connects to a base station via a RAT, receives sensing information from the base station, the sensing information including a power level selected by the base station to limit interference during a wireless sensing event using the RAT, and performs the wireless sensing event via the RAT based on the power level. By receiving the sensing information from the base station for use in a power control operation with the transmitter, the present solution leverages high-rate wireless components for high-resolution sensing while limiting interference caused by these wireless components during wireless sensing activities.

[0029] Accordingly, aspects of the present disclosure can improve network communications and extend wireless device capabilities by coordinating wireless sensing activities performed by various communication devices within a communication system, thereby limiting interference caused by collisions between wireless sensing signals and communication signals.

[0030] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0031] By way of example, an element, or any portion of an element, or any combination of elements can be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on a chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system can execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0032] Accordingly, in one or more example embodiments, the functions described can be implemented in hardware, software, or any combination thereof. If implemented in software, the functions can be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. 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 comprise a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), compact disk ROM (CD-ROM) or other optical disk storage, magnetic disk storage or other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable instructions or data structures accessed by a computer.

[0033] Figure 1 is a diagram illustrating an example of a wireless communications system and an access network 100. The wireless communications system (also referred to as a wireless wide area network (WW AN)) includes base stations 102, UEs 104, an Evolved Packet Core (EPC) 160, and a 5G Core (5GC) network 190. The base stations 102 can include macro cells (high power cellular base stations) and / or small cells (low power cellular base stations). The macro cells can include base stations. The small cells can include femtocells, picocells, and microcells. In an aspect, the UEs 104 can include a sensing management component 140 configured to manage wireless sensing activities performed by the UEs 104. The sensing management component 140 can include a sensing component 141 configured to perform wireless sensing operations, a configuration component 142 configured to provide sensing parameters to the sensing component 141 for performing wireless sensing operations, and a measurement component 143 configured to measure signal strength of wireless devices at the UEs 104. Further, in some aspects, the base stations 102 can include a sensing management component 198 configured to manage wireless sensing activities performed by wireless devices within the wireless communications system. The sensing management component 198 can include an interference management component 199 configured to determine sensing parameters for wireless sensing operations performed within the wireless communications system, a sensing component 141 configured to perform wireless sensing operations, and a measurement component 143 configured to determine signal information for wireless devices within the communications system. As described in detail herein, the sensing parameters can be used to reduce, minimize, or prevent interference between wireless sensing activities and data transmissions.

[0034] In some aspects, wireless sensing activities can include transmitting a wideband radar signal with a predefined waveform, and detecting a reflected signal corresponding to the radar signal. Further, the reflected signal can be processed according to different wireless sensing applications. The radar signal can be a chirp waveform or an OFDM waveform. Further, some applications for wireless sensing activities include motion detection, object identification, user interface applications, facial recognition, user activity detection, UE context detection, health monitoring, environmental imaging, communication assistance (e.g., accurate beam tracking), sidelink-based sensing (e.g., vehicle sensing in V2X), and Wi-Fi sensing (e.g., location detection, room mapping, etc.). Further, wireless sensing at higher frequencies as described herein can provide high bandwidth and large aperture from which to extract accurate range information, Doppler information, or angle information. Some benefits of wireless sensing at higher frequencies can include touchless interaction, ease of incorporation into UEs with small form factors, low power consumption, and non-visual based context awareness or sensing (e.g., non-line-of-sight (NLOS) context awareness).

[0035] The base stations 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with the EPC 160 through first backhaul links 132 (e.g., S I interface). The base stations 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can interface with the core network 190 through second backhaul links 184. In addition to other functions, the base stations 102 can perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment trace, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 can communicate directly or indirectly (e.g., through the EPC 160 or core network 190) with each other over third backhaul links 134 (e.g., X2 interface). The third backhaul links 134 can be wired or wireless.

[0036] The base stations 102 can wirelessly communicate with the UEs 104. Each of the base stations 102 can provide communication coverage for a respective geographic coverage area 110. There can be overlapping geographic coverage areas 110. For example, a small cell 102' can have a coverage area 110' that overlaps with one or more macrocells 102. A network that includes both small cell and macrocells can be known as a heterogeneous network. A heterogeneous network can also include Home Evolved Node Bs (eNBs) (HeNBs), which can provide service to a restricted group known as a closed subscriber group (CSG). The communication links 120 between the base stations 102 and the UEs 104 can include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to a base station 102 and / or downlink (DL) (also referred to as forward link) transmissions from a base station 102 to a UE 104. The communication links 120 can use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. These communication links can be through one or more carriers, where a carrier can be a set of

[0037] Certain UEs 104 can communicate using device-to-device (D2D) communication link 158. The D2D communication link 158 can use the DL / UL WWAN spectrum. The D2D communication link 158 can use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication can be through a variety of wireless D2D communications systems, such as for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0038] The wireless communications system can further include a Wi-Fi access point (AP) 150 in communication with Wi-Fi stations (STAs) 152 via communication links 154 in a 5 GHz unlicensed frequency spectrum. When communicating in an unlicensed frequency spectrum, the STAs 152 / AP 150 can perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available.

[0039] The small cell 102' can operate in a licensed and / or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell 102' can employ NR and use the same 5 GHz unlicensed frequency spectrum as used by the Wi-Fi AP 150. The small cell 102' employing NR in an unlicensed frequency spectrum can boost coverage and / or increase capacity for the access network.

[0040] Whether a small cell 102' or a large cell (e.g., macro base station), the base station 102 can include and / or be referred to as an eNB, gNodeB (gNB), or another type of base station. Some base stations, such as gNB 180 can operate in a traditional sub 6 GHz spectrum, in millimeter wave (mmW) frequencies, and / or near mmW frequencies in communication with the UE 104. When the gNB 180 operates in mmW or near mmW frequencies, the gNB 180 can be referred to as a mmW base station. Extremely high frequency (EHF) is a portion of the RF in the electromagnetic spectrum. EHF has a range from 30 GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters. Radio waves in this band can be referred to as a millimeter wave. Near mmW can extend down to a frequency of 3 GHz with a wavelength of 100 millimeters. The super high frequency (SHF) band extends between 3 GHz and 30 GHz, also referred to as centimeter wave. Communications using the mmW / near mmW radio frequency band (e.g., 3 GHz - 300 GHz) has extremely high path loss and a short range. The mmW base station 180 can utilize beamforming 182 with the UE 104 to compensate for the extremely high path loss and short range. The base station 180 and the UE 104 can each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate beamforming.

[0041] The base stations 180 can transmit to the UEs 104 on one or more transmission directions 182'. The UEs 104 can receive the beamformed signals from the base stations 180 on one or more reception directions 182". The UEs 104 can also transmit to the base stations 180 on one or more transmission directions. The base stations 180 can receive the beamformed signals from the UEs 104 on one or more reception directions. The base stations 180 / UEs 104 can perform beam training to determine the best reception and transmission directions for each of the base stations 180 / UEs 104. The transmission and reception directions for the base stations 180 can or can not be

[0042] The EPC 160 can include a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and a packet data network (PDN) gateway 172. The MME 162 can be in communication with a home subscriber server (HSS) 174. The MME 162 is the control node that processes the signaling between the UEs 104 and the EPC 160. Generally, the MME 162 provides bearer and connection management. All user Internet protocol (IP) packets are transferred through the serving gateway 166, which itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation as well as other functions. The PDN gateway 172 and the BM-SC 170 are connected to the IP services 176. The IP services 176 can include the Internet, an intranet, an IP multimedia subsystem (IMS), a PS streaming service, and / or other IP services. The BM-SC 170 can provide functions for MBMS user service provisioning and

[0043] The core network 190 can include an Access and Mobility Management Function (AMF) 192, other AMFs 193, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 can be in communication with a Unified Data Management (UDM) 196. The AMF 192 is the control node that processes the signaling between the UEs 104 and the core network 190. Generally, the AMF 192 provides QoS flow and session management. All user Internet protocol (IP) packets are transferred

[0044] A base station can include and / or be referred to as a gNB, NodeB, eNB, an access point, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), transmit reception point (TRP), or some other suitable terminology. The base station 102 provides wireless access to the EPC 160 or core network 190 for the UEs 104. Examples of UEs 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kiosk, a healthcare device, an implant, a sensor / actuator, a display, or any other similar functional device. Some of the UEs 104 can be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicle, heart monitor, etc.). The UE 104 can also be referred to as a station, a mobile, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.

[0045] While the following description can focus on 5G NR, the concepts described herein can be applicable to other similar areas, such as THz and other wireless technologies.

[0046] Figures 2A-2D The example diagrams 200, 230, 250, and 280 illustrate examples of example structures for wireless communications by base stations 102 and UEs 104 (e.g., for 5G NR communications). Figure 2A The diagram 200 illustrates an example of a first subframe within a 5G / NR frame structure.Figure 2B FIG. 230 is a diagram 230 illustrating an example of DL channels within a 5G / NR subframe. Figure 2C FIG. 250 is a diagram 250 illustrating an example of a second subframe within a 5G / NR frame structure. Figure 2D FIG. 280 is a diagram 280 illustrating an example of UL channels within a 5G / NR subframe. The 5G / NR frame structure can be FDD, TDD, or a combination thereof. In a frame (10 ms) for FDD, the number of subframes per frame is 10. In a frame (10 ms) for TDD, the number of subframes per frame is 10. The 5G / NR frame structure can be FDD, TDD, or a combination thereof. In a frame (10 ms) for FDD, the number of subframes per frame is 10. In a frame (10 ms) for TDD, the number of subframes per frame is 10. For TDD, the DL-to-UL ratio can be configurable. The UL-to-DL ratio can be Figure 2A , 2C In the example provided, the 5G / NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (mostly DL) and subframe 3 is configured with slot format 34 (mostly UL), where D is DL, U is UL, and X is flexibly used between DL / UL. While subframes 3, 4 are shown with slot formats 34, 28, respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, all UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. A UE is configured with a slot format (dynamically through DL control information (DCI), or semi- statically / statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI). Note that the following description also applies to a 5G / NR frame structure that is TDD.

[0047] Other wireless communication technologies can have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equally sized subframes (1 ms). Each subframe can include one or more time slots. A subframe can also include mini-slots, which can include 7, 4, or 2 symbols. Each slot can include 7 or 14 symbols depending on the slot configuration. For slot configuration 0, each slot can include 14 symbols, and for slot configuration 1, each slot can include 7 symbols. The symbols on the DL can be cyclic prefix (CP) OFDM (CP-OFDM) symbols. The symbols on the UL can be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also known as single carrier frequency division multiple access (SC-FDMA) symbols) (for power limited scenarios; limited to single stream transmission). The number of slots within a subframe is based on the slot configuration and the numerology. For slot configuration 0, different numerologies μ of 0 to 5 allow for 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different numerologies of 0 to 2 allow for 2, 4, and 8 slots per subframe, respectively. Accordingly, for slot configuration 0 and numerology μ, there are 14 symbols per slot and 2^μ slots per subframe.μ one slot. Subcarrier spacing and symbol length / duration are a function of numerology. Subcarrier spacing can equal 2 μ * 15 kHz, where μ is a numerology 0 through 5. As such, numerology μ = 0 has a subcarrier spacing of 15 kHz, while numerology μ = 5 has a subcarrier spacing of 480 kHz. Symbol length / duration is inversely related to subcarrier spacing. Symbol length / duration is inversely related to subcarrier spacing. Figures 2A-2D An example of a slot configuration 0 with 14 symbols per slot and numerology μ = 2 with 4 slots per subframe is provided. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μβ.

[0048] A resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs)) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0049] As Figure 2A illustrated in FIG. 2B, some of the REs carry reference (pilot) signals (RS) for the UE. The RS can include demodulation RS (DM-RS) (indicated as R x where 100x is the port number, although other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS can also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0050] Figure 2BAn example of various DL channels are illustrated within the subframes of a frame. The physical downlink control channel (PDCCH) carries DCI within one or multiple control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG including four consecutive REs in an OFDM symbol. A primary synchronization signal (PSS) can be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe / symbol timing and a physical layer identity. A secondary synchronization signal (SSS) can be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the aforementioned DM-RS. The physical broadcast channel (PBCH), which carries a master information block (MIB) that provides system bandwidth, and the location of system frame number (SFN), can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block. The physical downlink shared channel (PDSCH) carries user data, broadcast system information such as system information blocks (SIBs), and paging messages.

[0051] As explained in Figure 2C some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS can be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS can be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and on the particular PUCCH format used. The UE can transmit sounding reference signals (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb-2 structure, and the UE can transmit SRS on one of the combs. The SRS can be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0052] Figure 2D An example of various UL channels are illustrated within the subframes of a frame. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and HARQ ACK / NACK feedback. The PUSCH carries data, and can additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0053] Figure 3 is a block diagram of the base station 310 in communication with the UE 350 in an access network. In the DL, IP packets from the EPC 160 can be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter radio access technology (RAT) mobility, and measurement configuration; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error detection through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0054] The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, can include error detection on the transport channels, forward error correction (FEC) coding / decoding of the transport channels, interleaving, rate matching, mapping to physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols can then be split into parallel streams. Each stream can then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) and then combined together using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 374 can be used to determine the coding and modulation schemes, as well as for spatial processing. The channel estimate can be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can modulate an RF carrier with a respective spatial stream for transmission.

[0055] At the UE 350, each receiver 354RX receives a signal through its respective antenna 352. Each receiver 354RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time-domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. The soft decisions can be based on channel estimates computed by the channel estimator 358. The soft decisions are then decoded and de-interleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to the controller / processor 359, which implements layer 3 and layer 2 functionality.

[0056] The controller / processor 359 can be associated with a memory 360 that stores program codes and data. The memory 360 can be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0057] Similar to the functionality described in connection with the DL transmission by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0058] Channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted by the base station 310 can be used by the TX processor 368 to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 can be provided to different antenna 352 via separate transmitters 354TX. Each transmitter 354TX can modulate an RF carrier with a respective spatial stream for transmission.

[0059] The UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318RX receives a signal through its respective antenna 320. Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to a RX processor 370.

[0060] The controller / processor 375 can be associated with a memory 376 that stores program codes and data. The memory 376 can be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the UE 350. IP packets from the controller / processor 375 can be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0061] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 can be configured to perform aspects in connection with a sensing management component 140 of the base station 110, as described herein. Figure 1

[0062] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 can be configured to perform aspects in connection with a sensing management component 198 of the UE 350, as described herein. Figure 1

[0063] As described herein, a wireless communication system can enable wireless communication devices to employ a high frequency RAT, such as mmWave or THz, for wireless sensing and data transmission. To enable high resolution wireless sensing and high throughput data transmission to effectively coexist within a communication system, UEs and base stations can implement power control for wireless sensing. In particular, techniques for power control for wireless sensing minimize interference between data transmission operations and wireless sensing operations by employing a power level for wireless sensing activities that reduces, minimizes, or prevents conflict with other operations within the communication system.

[0064] ​​This disclosure provides techniques for power control for wireless sensing. As used herein, "power control" can refer to the selection of transmitter power output in a communication system. For example, a UE and a base station can implement sensing management techniques based on sensing information received by the UE from the base station to achieve power control for wireless sensing. In some aspects, the base station can send the UE a power level for performing wireless sensing activities, a range of power levels for performing wireless sensing activities, a maximum power level for performing wireless sensing activities, sensing permission for performing wireless sensing activities, or a reference power level for performing wireless sensing activities. Further, the base station can determine sensing information based on uplink activity from another UE or measurement information corresponding to UE activity captured by a neighboring device. In some other aspects, the wireless device can perform a first wireless sensing event, collect interference information based on the first wireless sensing event from a neighboring device, and determine a power level based on the interference information. Accordingly, the techniques of this disclosure enable wireless devices in a communication system to perform wireless sensing using power levels determined to reduce, minimize, or prevent interference with neighboring wireless devices.

[0065] Reference Figures 4-1 0. In a non-limiting aspect, system 400 is configured to provide power control for wireless sensing.

[0066] Figure 4 This is a diagram illustrating example communications and components between the base station and the UE. For example... Figure 4 As explained herein, system 400 may include UE 402 connected to base station 404 via a RAT operating in a dual-use frequency band. As described herein, in some aspects, "dual-use frequency band" may refer to a frequency band that can be used for at least high-rate data communication and high-resolution sensing. Some examples of dual-use frequency bands include mmWave and THz. Furthermore, system 400 may include a plurality of UEs 406(1)-(N) and a plurality of base stations 408(1)-(N). In some aspects, the plurality of UEs 406(1)-(N) and the plurality of base stations 408(1)-(N) may be located in a similar location to UE 402 and / or base station 404, or operate on the same network as UE 402 and / or base station 404. Additionally, in some aspects, base station 404 and the plurality of base stations 408(1)-(N) may be examples of base station 102, while UE 402 and the plurality of UEs 406(1)-(N) may be examples of UE 104.

[0067] Furthermore, UE 402 may include a sensing management component 140. (Refer to the above.) Figure 1As described, the sensing management component 140 may include a sensing component 141, a configuration component 142, and a measurement component 143. Furthermore, the UE 402 may include a receiving component 412 and a transmitter component 410. The receiving component 412 may include, for example, a radio frequency (RF) receiver for receiving signals described herein (e.g., reflected radar signals). The transmitter component 410 may include, for example, an RF transmitter for transmitting signals described herein. Further, the transmitter component 410 is configured to generate and transmit signals for sensing, as described herein. In one aspect, the receiving component 412 and the transmitter component 410 may coexist in a transceiver (e.g., transceiver 510).

[0068] Additionally, base station 402 may include sensing management component 198. (Refer to the above.) Figure 1 As described, the sensing management component 198 may include an interference management component 199, a sensing component 142, and a measurement component 143. Furthermore, the base station 404 may include a receiving component 416 and a transmitter component 414. Further, the transmitter component 410 is configured to generate a signal for sensing, as described herein. The receiving component 416 may include, for example, a radio frequency (RF) receiver for receiving the signal described herein. The transmitter component 414 may include, for example, an RF transmitter for transmitting the signal described herein. Further, the transmitter component 410 is configured to generate a signal for sensing, as described herein. In one aspect, the receiving component 416 and the transmitter component 414 may coexist in a transceiver (e.g., transceiver 610).

[0069] like Figure 4 As explained, UE 402 may attempt to perform one or more wireless sensing activities 418. Furthermore, due to the shared location of UE 402 and at least one of base station 404, multiple UEs 406(1)-(N), or multiple base stations 408(1)-(N), the wireless sensing activity 418 may interfere with communication between base station 404, multiple UEs 406(1)-(N), and / or other base stations 408(1)-(N). For example, the wireless sensing activity 418(1)-(N) performed by UE 402 may interfere with communication activities at UE 406(1), at least in part, based on the proximity between UE 402 and UE 406(1). Thus, UE 402, base station 404, multiple UEs 406(1)-(N), and / or multiple base stations 408(1)-(N) may employ sensing management techniques to reduce, prevent, or minimize interference 420 caused by the wireless sensing activity 418. It should be noted that interference 420 is described in dashed line format to indicate that the interference is optional, as it may not occur based on the features described herein for reducing or avoiding interference.

[0070] For example, such as Figure 4As illustrated, the sensing management component 198 of the base station 404 can transmit sensing information 422 to the UE 402. Upon receiving the sensing information 422, the sensing management component 140 can cause the UE 402 to perform the wireless sensing activity 418 in accordance with the sensing information 422 to reduce, minimize, or prevent interference 420.

[0071] In some aspects, the sensing information 422 can include a maximum power level. Further, the sensing management component 140 can perform the wireless sensing activity 418 via the transmitter component 410 at a power value that is less than or equal to the maximum power value of the sensing information 422. In some other aspects, the sensing management component 140 can determine whether an application of the wireless sensing activity 418 is a high priority application. Further, if the application is a high priority application, the sensing management component 140 can override the maximum power level and perform the wireless sensing activity 418 via the transmitter component 410 at a power level that is greater than the maximum power level of the sensing information 422.

[0072] In some aspects, the sensing information 422 can include a plurality of maximum power levels. Further, each maximum power level can be associated with a particular context. Further, the sensing management component 140 can identify a context of the wireless sensing activity 418 and perform the wireless sensing activity at a power level that is less than or equal to a particular maximum power level associated with the context as defined in the sensing information 422. In some other aspects, the sensing information 422 can include a reference value. Further, upon receiving the reference level, the sensing management component 140 can use the reference level to determine an actual power level to use in performing the wireless sensing activity 418. For example, the reference value can indicate that the actual power level should be a percentage of a preconfigured or previously assigned value (e.g., 60% of a power level for an uplink sounding reference signal (SRS)). In some aspects, the reference level can be a recommendation, and the sensing management component 140 can employ a different value based on one or more other factors (e.g., previous sensing activities, a context of the wireless sensing activity, etc.).

[0073] As Figure 4As illustrated, in some aspects, the sensing management component 140 can transmit a sensing request 424 to the base station 404 requesting sensing information 422. In some aspects, the sensing request 424 can include at least one of a request for a power level for a wireless sensing activity, a proposed power level for a wireless sensing activity, or a context identifier identifying an application of the wireless sensing activity 418. Further, in some aspects, in response to the sensing request 424, the base station 404 can transmit the sensing information 422 including at least one of a power level, a maximum power level, a power level range, an approval of the proposed power level, a rejection of the sensing request or the proposed power level, a sensing grant identifying resource information, and / or a power level for performing the wireless sensing activity 418. In some aspects, the resource information can include timing information for performing the wireless sensing activity 418, frequency information for performing the wireless sensing activity 418, and a power indication identifying a power level for performing the wireless sensing activity 418. In response to a rejection of the sensing request or the proposed power level (e.g., the sensing information 422 can include a rejection communication), the base station 404 can transmit a second proposed power level, or the UE 402 can transmit a second sensing request or a second proposed power level for consideration by the base station 404.

[0074] Further, as Figure 4 illustrated, the UE 402, the plurality of UEs 406(1)-(N), and the plurality of base stations 408(1)-(N) can transmit measurement information 426 to the base station 404. In some aspects, the measurement information 426 can include signal strength information (e.g., a received signal strength indicator (RSSI)) determined by the neighboring wireless devices. Additionally, the UE 402, the plurality of UEs 406(1)-(N), and the plurality of base stations 408(1)-(N) can perform a plurality of communication operations 428 (e.g., transmissions and receptions) with the base station 404. Further, the sensing management component 198 can determine the sensing information 422 based at least in part on the measurement information 426 and the communication operations 428. For example, the base station 404 can determine a maximum power level or resource information for the wireless sensing activity 418 based at least in part on utilizing the measurement information 426 and the communication operations 428 to reduce, minimize, or prevent interference 420 at one or more of the base station 404, the plurality of UEs 406(1)-(N), and / or the plurality of base stations 408(1)-(N) during performance of the wireless sensing activity 418(1).

[0075] In some aspects, the system 400 can implement a closed-loop power control approach for interference management of the wireless sensing activity 418 performed by the UE 402 or the base station 404. As used herein, “closed-loop power control” can refer to a power control technique that is based on feedback from another device. For example, as Figure 4As illustrated, the base station 404 can endeavor to perform one or more wireless sensing activities 430(1)-(N). Further, due to the common location of the UE 402, the plurality of UEs 406(1)-(N), or at least one of the plurality of base stations 408(1)-(N) and the base station 404, the wireless sensing activities 430(1)-(N) can interfere with communications between the UE 402, the base station 404, the plurality of UEs 406(1)-(N), and the other base stations 408(1)-(N). For example, the wireless sensing activities 430(1)-(N) performed by the base station 404 can interfere with communication activities at the UE 406(1) based at least in part on the proximity between the base station 404 and the UE 406(1).

[0076] In some aspects, the base station 404 can perform a first wireless sensing activity 430(1) to cause interference 432. Further, the base station 404 can receive measurement information 426 from the plurality of UEs 406(1)-(N) and the plurality of base stations 408(1)-(N) corresponding to the interference 432. In some aspects, the measurement information 426 can include measurements of the interference 432 at the plurality of UEs 406(1)-(N) and the plurality of base stations 408(1)-(N). Further, the base station 404 can employ the sensing management component 198 to determine a power level for a subsequent wireless sensing activity 430(2)-(N) based on the measurement information 426. In particular, the sensing management component 198 can identify a device that detected the interference 432, and determine a power level that reduces, minimizes, or prevents subsequent interference at the identified device in response to the wireless sensing activity 430(2)-(N). For example, the sensing management component 198 can determine a power level that will result in interference measurements at the identified device that are below a preconfigured threshold.

[0077] Figure 5 FIG. 500 is a diagram 500 illustrating an example of a hardware implementation for a UE 502 employing a processing system 514. The processing system 514 can be implemented with a bus architecture, as represented by the bus 524. The bus 524 can include any number of interconnecting buses and / or bridges depending on the specific application of the processing system 514 and the overall design constraints. The bus 524 links together various circuits including one or more processors and / or hardware components, represented by the processor 504, the sensing management component 140, the sensing component 141, the configuration component 142, the measurement component 143, and computer-readable media (e.g., non-transitory computer-readable media) / memory 506. The bus 524 can also link various other circuits such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art, and therefore, will not be described any further.

The transceiver 510 provides a means for communicating with various other apparatus over a transmission medium. The transceiver 510 receives a signal from the one or more antennas 520, extracts information from the received signal, and provides the extracted information to the processing system 514, specifically the reception component 412. In addition, the transceiver 510 receives information from the processing system 514, specifically the transmission component 410, and based on the received information, generates a signal to be applied to the one or more antennas 520. The processing system 514 includes a processor 504 coupled to a computer-readable medium / memory 506. The processor 504 is responsible for general processing, including the execution of software stored on the computer-readable medium / memory 506. The software, when executed by the processor 504, causes the processing system 514 to perform the various functions described supra for any particular apparatus.

The processing system 514 can be a component of the UE 350 and can include the memory 360 and / or at least one of the TX processor 368, the RX processor 356, and the controller / processor 359. Alternatively, the processing system 514 can be the entire UE (e.g., see 350). Figure 3

[0079] ​The sensing component 141 can be configured to perform wireless sensing activities (e.g., wireless sensing activities 420(1)-(N)) using the transmitter component 410 and the receiving component 412. In some aspects, the sensing component 141 can direct the transmitter component 410 to transmit radar signals having a predefined waveform (e.g., a frequency-modulated continuous wave (FMCW) radar, a pulsed radar, etc.) and receive, via the receiving component 412, reflection signals corresponding to the radar signals. Additionally, the sensing component 141 can perform radar signal processing using the radar signals and the reflection signals to determine processing information, e.g., the sensing component 141 can correlate the reflection signals with the originally transmitted radar signals. In some aspects, correlating the transmitted radar signals and the reflection signals can include comparing amplitude differences and identifying time shift information. Further, the processing information can be used to make sensing determinations. For example, the sensing component 141 can apply machine learning techniques to the correlation information to classify events or objects, or predict outcomes. In some aspects, the sensing component 141 can be used to generate images of an environment, determine high resolution positioning information, facilitate establishing or adjusting a beamformed communication link, or detect human activity (e.g., gestures, health activity, etc.).

[0080] The configuration component 142 can be configured to determine a power level of the transmitter component 410 and / or other resource information for wireless sensing activities (e.g., wireless sensing activities 420(1)-(N)) performed by the sensing component 141. In some aspects, the configuration component 142 can receive sensing information 422 and configure the wireless sensing activities 418 based on the sensing information 422. For example, as described in detail herein, the configuration component 142 can determine a power level for the transmitter component 410 during the wireless sensing activities.

[0081] In some aspects, the configuration component 142 can determine the power level based on a context or priority of the wireless sensing activities 418. Additionally or alternatively, the configuration component 142 can determine the power level based on a maximum power level or a reference power level specified by the base station 404. In some other aspects, the configuration component 142 can determine the power level based on interference measurements determined by the measurement component 143. Further, the configuration component 142 can schedule the wireless sensing activities 418 based on a sensing grant included in the sensing information 422.

As such, in one configuration, the aforementioned means can be the TX processor 368, the RX processor 356, and the controller / processor 359 configured to perform the functions recited by the aforementioned means.

[0084] Figure 6 FIG. 6 is a diagram 600 illustrating an example of a hardware implementation for a base station 602 employing a processing system 614. The processing system 614 can be implemented with a bus architecture, as represented by the bus 624. The bus 624 can include any number of interconnecting buses and bridges depending on the specific application of the processing system 614 and the overall design constraints. The bus 624 links together various circuits including one or more processors and / or hardware components, represented by the processor 604, the sensing management component 198, the interference management component 199, the sensing component 141, the measurement component 143, and the computer-readable medium / memory 606.

The processing system 614 can be a component of the base station 310 and can include the memory 376 and / or at least one of the TX processor 316, the RX processor 370, and the controller / processor 375. Alternatively, the processing system 614 can be the entire base station (e.g., see 310 of FIG. 1). Figure 3

[0086] The interference management component 199 can be configured to determine power levels for transmitter components (e.g., the transmitter component 410 and the transmitter component 414) within the system 400. In addition, the interference management component 199 can be configured to determine resource information for wireless sensing activity (e.g., the wireless sensing activity 418(1)- (N) performed by the UE 402, the wireless sensing activity 430(1)- (N) performed by the base station 602, etc.) within the system 400.

[0087] ​In some aspects, the interference management component 199 can determine the sensing information 422 and transmit the sensing information 422 to the UE 402. Further, the UE 404 can use the sensing information 422 to determine a power level of the transmitter component 410 when performing the wireless sensing activity 418.
