Background Technology

[0004] Related technical descriptions

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, broadcasting, or other similar services. These wireless communication systems may employ multiple access technologies that enable communication with multiple users by sharing available wireless communication system resources.

[0006] Despite significant technological advancements in wireless communication systems over the years, challenges remain.

[0025] Various aspects of this disclosure relate to techniques for mitigating interference to ultra-wideband (UWB) devices when operating in the same frequency band as wireless telecommunication equipment (e.g., 4G, 5G, and / or 6G devices). In other words, the aspects described herein provide techniques for achieving co-channel coexistence between wireless telecommunication equipment and UWB devices.

[0026] Coexistence refers to the operation of different types of wireless devices in the same frequency band (e.g., operating according to different standards, using different technologies such as UWB or cellular technology). While it might be ideal for different types of wireless devices to have different frequencies, the spectrum is finite. Furthermore, the ever-increasing number of wireless device types makes it difficult, and in some cases impossible, to allocate separate spectrum for each type. Therefore, spectrum can be shared between different types of wireless devices.

[0027] For example, portions of the spectrum can be shared between UWB devices and wireless telecommunications equipment. UWB is a low-power, short-range, high-bandwidth radio technology that provides precise positioning and tracking. UWB is a direct connection between two UWB devices, consisting of bursts of radio waves being transmitted and received. These "pulse-based" radio waves are used to measure location by precisely timing the time each radio pulse takes to travel between the two UWB devices.

[0028] The goal of UWB technology is to utilize the spectrum of UWB Channel 5 corresponding to the 6,240MHz-6,740MHz band, the spectrum of UWB Channel 9 corresponding to the 7,740MHz-8,240MHz band, and the spectrum of UWB Channel 10 corresponding to the 8,240MHz-8,740MHz band. However, unfortunately, for UWB technology, UWB devices may need to operate in these frequency ranges with other wireless telecommunication devices (e.g., network entities such as those enabling 4G, 5G, and / or 6G). Therefore, channel interference caused by UWB devices and wireless telecommunication devices communicating in the same frequency range (especially in areas with high throughput and / or a large number of devices) may be unavoidable unless mitigation techniques are applied to minimize and / or completely avoid channel interference. Channel interference caused by the coexistence of wireless telecommunication devices and UWB devices operating in the same frequency band can lead to data loss, inefficient ranging sessions between UWB devices, and / or adversely affect sensitive UWB devices.

[0029] Therefore, the aspects described herein provide techniques for mitigating channel interference to achieve co-channel coexistence between wireless telecommunication equipment and UWB equipment. For example, one or more network entities (e.g., example wireless telecommunication equipment) operating in the same frequency band as one or more UWB devices participating in and / or located near a UWB ranging session may perform one or more interference mitigation procedures. Such procedures can help reduce interference in the frequency bands used for UWB ranging sessions and cellular (e.g., 4G, 5G, and / or 6G) communications. Various interference mitigation procedures described in detail below can be considered to reduce channel interference.

[0030] In some aspects, the network entity is triggered to perform an interference mitigation procedure based on receiving signaling from a UWB-enabled UE (e.g., operating in the same frequency band as the network entity) instructing the initiation of a UWB ranging session between the UWB-enabled UE and another UWB device. For example, the UWB-enabled UE may be configured to communicate using both UWB and cellular technologies. In some aspects, the network entity is triggered to perform an interference mitigation procedure based on determining that the location of the UWB-enabled UE (e.g., operating in the same frequency band as the network entity) is within a threshold distance of another UWB device participating in the UWB ranging session. In some aspects, the network entity is triggered to perform an interference mitigation procedure based on determining that the location of the UWB-enabled UE is within an area where UWB ranging sessions frequently occur (and in some cases, within that area during specific times when UWB ranging sessions frequently occur).

[0031] The implementation of interference mitigation processes can help reduce interference in the frequency bands used for UWB ranging sessions and cellular communications, thereby reducing UWB packet loss and improving the reliability of UWB communications. Furthermore, reducing interference in the frequency band can help avoid adversely affecting sensitive UWB devices communicating in that band.

[0032] Introduction to wireless communication networks

[0033] The techniques and methods described herein can be used in a variety of wireless communication networks. While aspects may be described herein using terms commonly associated with 3G, 4G, 5G, and / or 6G wireless technologies, aspects of this disclosure are equally applicable to other communication systems and standards not explicitly mentioned herein.

[0034] Figure 1 An example of a wireless communication network 100 in which the aspects described herein can be implemented is depicted.

[0035] Generally, wireless communication network 100 includes various network entities (optionally, network elements or network nodes). Network entities are typically communication devices and / or communication functions performed by communication devices (e.g., user equipment (UE), base station (BS), components of the BS, servers, etc.). Since such communication devices are part of wireless communication network 100 and facilitate wireless communication, they may be referred to as wireless communication devices. For example, various functions of the network and various devices associated with and interacting with the network may be considered network entities. Furthermore, wireless communication network 100 includes terrestrial and non-terrestrial aspects. The terrestrial aspect includes ground-based network entities (e.g., BS 102), and the non-terrestrial aspect includes satellite 140 and aircraft 145, which may include onboard network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and UEs.

[0036] In the depicted example, wireless communication network 100 includes BS 102, UE 104 and one or more core networks (such as Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190) that interoperate to provide communication services over various communication links, including wired and wireless links.

[0037] Figure 1 Various example UEs 104 are described, which may more generally include: cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players, cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, Internet of Things (IoT) devices, always-on (AON) devices, edge processing devices, or other similar devices. UE 104 may also be more generally referred to as mobile devices, wireless devices, stations, mobile stations, subscriber stations, mobile subscriber stations, mobile units, subscriber units, wireless units, remote units, remote devices, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, and others.

[0038] BS 102 communicates wirelessly with UE 104 via communication link 120 (e.g., transmitting or receiving signals to or from UE 104). Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to BS 102 and / or downlink (DL) (also known as forward link) transmission from BS 102 to UE 104. In various aspects, communication link 120 may utilize multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity.

[0039] BS 102 may typically include: NodeB, enhanced NodeB (eNB), next-generation enhanced NodeB (ng-eNB), next-generation NodeB (gNB or gNodeB), access point, transceiver base station, radio base station, radio transceiver, transceiver functionality, transmit / receive point, and / or others. Each of BS 102 provides communication coverage for a corresponding coverage area 110, which may sometimes be referred to as a cell, and in some cases may overlap (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, BS may provide communication coverage for macro cells (covering a relatively large geographic area), pico cells (covering a relatively small geographic area, such as a stadium), femtocells (covering a relatively small geographic area (e.g., a home)), and / or other types of cells.

[0040] Generally speaking, a cell can refer to a portion, partition, or segment of wireless communication coverage served by network entities within a wireless communication network. A cell can have geographical characteristics (such as a geographical coverage area) and radio frequency characteristics (such as time and / or frequency resources dedicated to the cell). For example, multiple cells using different frequency resources (e.g., bandwidth portions) and / or different time resources can cover a specific geographical coverage area. As another example, a single cell can cover a specific geographical coverage area.

[0041] Although BS 102 is described as a single communication device in various aspects, it can be implemented in a variety of configurations. For example, to give a few examples, one or more components of the base station can be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC. In another example, various aspects of the base station can be virtualized. More generally, a base station (e.g., BS 102) can include components located at a single physical location or components located at various physical locations. In examples where the base station includes components located at various physical locations, the various components can each perform functions, such that the various components collectively achieve functionality similar to a base station located at a single physical location. In some aspects, a base station including components located at various physical locations can be referred to as a decomposed radio access network architecture (such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture). Figure 2 An example decomposed base station architecture is depicted and described.

[0042] Different BSs 102 within the wireless communication network 100 can also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) can interface with 5GC 190 via a second backhaul link 184. BSs 102 can communicate directly or indirectly with each other (e.g., via EPC 160 or 5GC 190) on a third backhaul link 134 (e.g., X2 interface), which can be wired or wireless.

[0043] Wireless communication network 100 can subdivide the electromagnetic spectrum into various categories, bands, channels, or other characteristics. In some aspects, subdivision is provided based on wavelength and frequency, where frequency may also be referred to as carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410MHz to 7125MHz, which is often (interchangeably) referred to as “sub-6GHz”. Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250MHz to 52,600MHz, which is sometimes (interchangeably) referred to as “millimeter wave” (“mmW” or “mmWave”). Base stations configured to communicate using mmWave / near mmWave radio bands (e.g., mmWave base stations such as BS 180) can utilize beamforming (e.g., 182) with UEs (e.g., 104) to improve path loss and range.

[0044] The communication link 120 between BS 102 and, for example, UE 104 can be via one or more carriers, which may have different bandwidths (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz and / or other MHz) and may be aggregated in various ways. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL).

[0045] Compared to lower-frequency communication, communication using higher frequency bands may have higher path loss and shorter range. Therefore, some base stations (e.g., Figure 1 The beamforming 182 of the BS 180 (180) with the UE 104 can be used to improve path loss and range. For example, the BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming. In some cases, the BS 180 may transmit beamformed signals to the UE 104 in one or more transmit directions 182''. The UE 104 may receive beamformed signals from the BS 180 in one or more receive directions 182''. The UE 104 may also transmit beamformed signals to the BS 180 in one or more transmit directions 182''. The BS 180 may also receive beamformed signals from the UE 104 in one or more receive directions 182''. The BS 180 and UE 104 may then perform beamforming training to determine the optimal receive and transmit directions for each of the BS 180 and UE 104. It is worth noting that the transmit and receive directions of the BS 180 may or may not be the same. Similarly, the transmission and reception directions of UE 104 may or may not be the same.

[0046] The wireless communication network 100 also includes a Wi-Fi AP 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, unlicensed spectrum in 2.4 GHz and / or 5 GHz.

[0047] Some UEs 104 may use device-to-device (D2D) communication links 158 to communicate with each other. The D2D communication link 158 may use one or more sidelink channels, such as physical sidelink broadcast channel (PSBCH), physical sidelink discovery channel (PSDCH), physical sidelink shared channel (PSSCH), physical sidelink control channel (PSCCH), and / or physical sidelink feedback channel (PSFCH).

[0048] EPC 160 may include various functional components, including: Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and / or Packet Data Network (PDN) Gateway 172, as in the illustrated example. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Generally, MME 162 provides bearer and connectivity management.

[0049] Generally, user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP service 176, which may include, for example, the Internet, intranet, IP Multimedia Subsystem (IMS), packet-switched (PS) streaming service, and / or other IP services.

[0050] The BM-SC 170 provides functions for MBMS user service dispatch and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, can be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and / or can be used to schedule MBMS transmissions. The MBMS gateway 168 can be used to distribute MBMS services to BS 102 belonging to a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and / or can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0051] 5GC 190 may include various functional components, including: Access and Mobility Management Function (AMF) 192, other AMFs 193, Session Management Function (SMF) 194, and User Plane Function (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196.

[0052] AMF 192 is the control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides services such as Quality of Service (QoS) flow and session management.

[0053] Internet Protocol (IP) packets are transmitted via UPF 195, which connects to IP service 197 and provides the UE with IP address allocation and other functions for 5GC 190. IP service 197 may include, for example, the Internet, intranet, IMS, PS streaming service, and / or other IP services.

[0054] In various aspects, to give a few examples, network entities or network nodes can be implemented as aggregated base stations, decomposed base stations, components of base stations, integrated access and backhaul (IAB) nodes, relay nodes, and sidelink nodes.

[0055] Figure 2 An example decomposed base station 200 architecture is depicted. The decomposed base station 200 architecture may include one or more central units (CUs) 210, which may communicate directly with the core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed base station units, such as a near real-time (near-RT) RAN Intelligent Controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a Service Management and Orchestration (SMO) framework 205, or both. CUs 210 may communicate with one or more distributed units (DUs) 230 via corresponding midhaul links (such as F1 interfaces). DUs 230 may communicate with one or more radio units (RUs) 240 via corresponding fronthaul links. RUs 240 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some specific implementations, UE 104 may be served simultaneously by multiple RUs 240.

[0056] Each unit in a cell (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO frame 205) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cell, or an associated processor or controller providing instructions to the unit's communication interface, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally or alternatively, a unit may include a wireless interface that may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver) configured to receive signals on a wireless transmission medium or transmit signals to one or more other units, or both.

[0057] In some aspects, CU 210 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by CU 210. CU 210 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP)), control plane functions (e.g., Central Unit-Control Plane (CU-CP)), or combinations thereof. In some implementations, CU 210 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, CU-UP units can communicate bidirectionally with CU-CP units via an interface such as an E1 interface. CU 210 can be implemented to communicate with DU 230 for network control and signaling purposes, as needed.

[0058] DU 230 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 240s. In some aspects, DU 230 may at least partially host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) according to functional splits (such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0059] Lower-layer functionality can be implemented by one or more RU 240s. In some deployments, an RU240 controlled by a DU 230 may correspond to a logical node that hosts RF processing functions or low-PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, or Physical Random Access Channel (PRACH) extraction and filtering, or both, at least in part based on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UE 104s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration enables the implementation of the DU 230 and CU 210 in cloud-based RAN architectures such as vRAN architectures.

[0060] SMO framework 205 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 205 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, SMO framework 205 can be configured to interact with a cloud computing platform such as Open Cloud (O-Cloud) 290 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some implementations, SMO framework 205 can communicate with the hardware aspects of the 4G RAN (such as Open eNB (O-eNB) 211) via the O1 interface. Additionally, in some implementations, SMO framework 205 can communicate directly with one or more RU 240s via the O1 interface. SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of SMO framework 205.

[0061] The non-RT RIC 215 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 225. The non-RT RIC 215 can be coupled to or communicate with the near-RT RIC 225, such as via an A1 interface. The near-RT RIC 225 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as via an E2 interface, through data collection and action, connecting one or more CU 210s, one or more DU 230s, or both, and O-eNBs to the near-RT RIC 225.

[0062] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 225 and may be received from non-network data sources or network functions at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns in performance and use AI / ML models to perform corrective actions via the SMO framework 205 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0063] Figure 3 Various aspects of examples BS 102 and UE 104 are described.

[0064] Generally, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a-334t (collectively referred to as 334), transceivers 332a-332t (collectively referred to as 332) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., data source 312) and the wireless reception of data (e.g., data sink 339). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement the various functions described herein related to wireless communication.

[0065] Generally, UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-352r (collectively referred to as 352), transceivers 354a-354r (collectively referred to as 354) including modulators and demodulators, and other aspects for implementing wireless transmission of data (e.g., retrieved from data source 362) and wireless reception of data (e.g., provided to data sink 360). UE 104 includes a controller / processor 380 that can be configured to implement the various functions described herein related to wireless communication.

[0066] Regarding example downlink transmission, BS 102 includes a transmission processor 320 that can receive data from data source 312 and control information from controller / processor 340. This control information may be for a Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid Automatic Repeat Request (HARQ) Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Group Common PDCCH (GC PDCCH), and / or others. In some examples, this data may be for a Physical Downlink Shared Channel (PDSCH).

[0067] The transmitter processor 320 can process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmitter processor 320 can also generate reference symbols (such as those for the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH demodulation reference signal (DMRS), and channel state information reference signal (CSI-RS)).

[0068] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols where applicable, and can provide the output symbol stream to the modulators (MODs) in transceivers 332a-332t. Each modulator in transceivers 332a-332t can process the corresponding output symbol stream to obtain an output sample stream. Each modulator can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signal from the modulators in transceivers 332a-332t can be transmitted via antennas 334a-334t respectively.

[0069] To receive downlink transmissions, UE 104 includes antennas 352a-352r that receive downlink signals from BS 102 and provide the received signals to demodulators (DEMODs) in transceivers 354a-354r respectively. Each demodulator in transceivers 354a-354r can adjust (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator can further process the input sample to obtain the received symbols.

[0070] The RX MIMO detector 356 acquires received symbols from all demodulators in transceivers 354a-354r, performs MIMO detection on the received symbols where applicable, and provides the detected symbols. The receive processor 358 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide the decoded data for UE 104 to data sink 360, and provide the decoded control information to controller / processor 380.

[0071] Regarding example uplink transmission, UE 104 also includes a transmit processor 364 that receives and processes data from data source 362 (e.g., for PUSCH) and control information from controller / processor 380 (e.g., for Physical Uplink Control Channel (PUCCH)). Transmit processor 364 can also generate reference symbols for reference signals (e.g., for Sounding Reference Signal (SRS)). Symbols from transmit processor 364 can be pre-decoded by TX MIMO processor 366, where applicable, further processed by modulators in transceivers 354a-354r (e.g., for SC-FDM), and transmitted to BS 102.

[0072] At BS 102, uplink signals from UE 104 can be received by antennas 334a-334t, processed by demodulators in transceivers 332a-332t, detected where applicable by RX MIMO detector 336, and further processed by receiver processor 338 to obtain decoded data and control information transmitted by UE 104. Receiver processor 338 can provide the decoded data to data sink 339 and the decoded control information to controller / processor 340.

[0073] Memory 342 and memory 382 can store data and program code for BS 102 and UE 104, respectively.

[0074] Scheduler 344 can schedule UEs to transmit data on the downlink and / or uplink.

[0075] In various respects, BS 102 can be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 312, scheduler 344, memory 342, transmit processor 320, controller / processor 340, TX MIMO processor 330, transceiver 332a-332t, antenna 334a-334t, and / or other aspects described herein. Similarly, “receiving” can refer to various mechanisms that acquire data, such as from antenna 334a-334t, transceiver 332a-332t, RX MIMO detector 336, controller / processor 340, receive processor 338, scheduler 344, memory 342, and / or other aspects described herein.

[0076] In various respects, UE 104 can also be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 362, memory 382, ​​transmit processor 364, controller / processor 380, TX MIMO processor 366, transceiver 354a-354t, antenna 352a-352t, and / or other aspects described herein. Similarly, “receiving” can refer to various mechanisms that acquire data, such as from antenna 352a-352t, transceiver 354a-354t, RX MIMO detector 356, controller / processor 380, receive processor 358, memory 382, ​​and / or other aspects described herein.

[0077] In some respects, the processor can be configured to perform various operations (such as those associated with the methods described herein) and to send (output) data to or receive data from another interface configured to send or receive data, respectively.

[0078] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes the use of wireless communication networks (such as Figure 1 All aspects of the data structure of the wireless communication network 100.

[0079] Specifically, Figure 4A Figure 400 is an example of the first subframe within a 5G (e.g., 5G NR) frame structure. Figure 4B Figure 430 illustrates an example of a DL channel within a 5G subframe. Figure 4C Figure 450 illustrates an example of the second subframe within a 5G frame structure, and Figure 4DFigure 480 illustrates an example of a UL channel within a 5G subframe.

[0080] Wireless communication systems can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a cyclic prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single-Carrier Frequency Division Multiplexing (SC-FDM) will (e.g., as...) Figure 4B and Figure 4D The system bandwidth (as depicted in the text) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0081] Wireless communication frame structures can be frequency division duplex (FDD), where for a specific set of subcarriers, subframes within that set are dedicated to either deep (DL) or ultra-low (UL). Wireless communication frame structures can also be time division duplex (TDD), where for a specific set of subcarriers, subframes within that set are dedicated to both DL and UL.

[0082] exist Figure 4A and Figure 4C In this example, the wireless communication frame structure is TDD, where D stands for DL, U for UL, and X is flexibly used between DL and UL. The UE can configure the time slot format via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling). In the depicted example, a 10ms frame is divided into 10 equal-sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. Subframes may also include micro-slots, which typically have fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0083] In some respects, the number of time slots within a subframe is based on the time slot configuration and parameter set. For example, for time slot configuration 0, different parameter sets ( Parameters 0 through 5 allow each subframe to have 1, 2, 4, 8, 16, and 32 time slots, respectively. For time slot configuration 1, different parameter sets 0 through 2 allow each subframe to have 2, 4, and 8 time slots, respectively. Therefore, for time slot configuration 0 and parameter sets... There are 14 symbols / slots and Each time slot / subframe. Subcarrier spacing and symbol length / duration are functions of a parameter set. Subcarrier spacing can be equal to...

[0084] ,in It is the parameter set from 0 to 5. Therefore, the parameter set... It has a subcarrier spacing of 15 kHz and a parameter set It has a subcarrier spacing of 480 kHz. The symbol length / duration is negatively correlated with the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D It provides slot configuration 0 with 14 symbols per slot and parameter set with 4 slots per subframe. Example. The time slot duration is 0.25ms, the subcarrier spacing is 60kHz, and the symbol duration is approximately... .

[0085] like Figure 4A , Figure 4B , Figure 4C and Figure 4D As depicted, the resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also known as a physical RB (PRB)) extending for, for example, 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.

[0086] like Figure 4A As illustrated in the example, some REs in the RE carry information for the UE (e.g., Figure 1 and Figure 3 The reference (pilot) signal (RS) for the UE (104) may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0087] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0088] The Primary Synchronization Signal (PSS) can be located within symbol 2 of a specific subframe of the frame. The PSS is generated by the UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identifier.

[0089] The secondary synchronization signal (SSS) can be located in symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the physical layer cell identifier group number and radio frame timing.

[0090] Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block. The MIB provides the System Frame Number (SFN) and the number of Restricted Frames (RBs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (such as System Information Blocks (SIBs)) not transmitted via the PBCH, and / or paging messages.

[0091] like Figure 4C As illustrated, some REs in the REs carry DMRS for channel estimation at the base station (indicated as R for a particular configuration, but other DMRS configurations are possible). The UE can transmit DMRS for PUCCH and DMRS for PUSCH. PUSCH DMRS can be transmitted, for example, in the first or second symbol before the PUSCH. PUCCH DMRS can be transmitted in different configurations depending on whether a short or long PUCCH is being transmitted and depending on the specific PUCCH format used. UE104 can transmit a Sounding Reference Signal (SRS). SRS can be transmitted, for example, in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of the comb teeth. SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0092] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI.

[0093] All aspects related to UWB

[0094] Ultra-wideband (UWB) is a short-range wireless communication protocol that uses radio waves, similar to Bluetooth and Wi-Fi. However, compared to Bluetooth and Wi-Fi, UWB operates in a higher frequency band and uses a wider bandwidth (500 MHz or more) (e.g., as the name "ultra-wideband" implies). These unique characteristics of UWB allow it to measure distance and determine location more accurately than other technologies, thus providing a foundation for building more secure applications.

[0095] UWB transmitters operate by transmitting billions of pulses across a wide frequency spectrum. Corresponding receivers convert these pulses into data by listening to a familiar sequence of pulses transmitted by the transmitter. The pulses are transmitted to the receiver approximately every two nanoseconds to a geosecond, which helps UWB achieve its real-time accuracy. Specifically, these "pulse-based" radio waves are used to measure location by precisely timing the time it takes for the radio pulses to travel between two different devices.

[0096] For example, when a UWB-enabled mobile device (such as a smartphone, smartwatch, smart key, etc.) approaches another UWB device (e.g., mobile or stationary), the devices initiate "ranging" (also referred to herein as performing a "UWB ranging session"). Ranging is accomplished by performing a time-of-flight (ToF) measurement between the devices. The TOF is calculated by measuring the round-trip time of challenge / response packets. Depending on the type of application, either the UWB-enabled mobile device or the other UWB device calculates the precise location of the other device.

[0097] The real-time accuracy of UWB measurements means that a UWB-enabled system can determine the precise location of a device and whether it is stationary or moving toward or away from the device performing the measurement with a very high degree of determinism. For example, a UWB-enabled system can be able to sense whether a UWB-enabled mobile device is moving toward a locked door and determine whether the UWB-enabled device is inside or outside the doorway to determine whether the lock should remain closed or open when the UWB-enabled mobile device reaches a point (e.g., a threshold distance from the locked door).

[0098] Example UWB application

[0099] In some cases, UWB technology is used for access control, specifically for access systems in vehicles, commercial buildings, and / or residential homes, to name just a few.

[0100] For example, in the automotive industry, digital key technology (e.g., remote access technology) is used to provide users with the ability to unlock / lock and turn on / off their vehicles from their mobile devices, such as via an app downloaded to the mobile device. In contrast to unlocking and locking the vehicle, some vehicles will automatically lock and / or unlock when the user's digital key is determined to be within a threshold distance of the vehicle, while other digital keys require the user to manually lock and / or unlock the car using an associated app (e.g., within the threshold distance).

[0101] Digital keys can use a combination of UWB, Bluetooth, or Bluetooth Low Energy (BLE) and / or Near Field Communication (NFC) to enable a user's mobile device to "communicate" with the user's vehicle (e.g., more specifically, a UWB device installed in a car). For example, the user's mobile device can use Bluetooth coarse location estimation to determine if the device is within a threshold distance of the user's vehicle. Bluetooth coarse location estimation may rely on signal strength (e.g., Received Signal Strength Indicator (RSSI)) to estimate the approximate position of the mobile device relative to the vehicle (as opposed to a precise position). When the mobile device determines that it is within the threshold distance of the vehicle, the mobile device can initiate a UWB ranging session with the vehicle's UWB device. For example, UWB secure ranging technology can be used to transmit radio energy pulses between the mobile device and the UWB device, and further perform Time-of-Flight (ToF) measurements between the devices. In some cases, strong encryption is used to help ensure that distance measurements cannot be hacked by car thieves and / or that distances can be established quickly, accurately, and securely. UWB secure ranging consumes very little power while allowing for accurate measurements. In addition, unlike many other distance measurement technologies, UWB can operate under adverse environmental conditions, including, for example, fog, smoke, and / or rain.

[0102] Beyond digital key applications, UWB ranging can also be used with smart tags to allow owners to locate lost items, providing not only angular direction and / or distance, but in some cases azimuth and / or elevation. Additionally, UWB ranging enables secure, tap-free mobile transactions. For example, a user with a mobile device can approach a register to purchase an item, and payment for the item can be automatic without the user needing to pull out their mobile device to complete the purchase.

[0103] It should be noted that the above applications of UWB technology are merely examples, and many other UWB applications exist (not listed above).

[0104] Various aspects related to UWB spectrum

[0105] UWB technology operates in designated unlicensed spectrum. Specifically, for example, UWB technology used in digital key applications does not require dedicated spectrum. Instead, UWB technology coexists on an interference-free / unprotected basis in unlicensed spectrum used by existing spectrum users, such as satellite systems, scientific applications, and / or radar systems.

[0106] The spectrum used for UWB applications is divided into various UWB channels, such as at least 500 MHz wide. Figure 5The UWB spectrum 500 is depicted as divided into various UWB channels with their corresponding bandwidths. As shown, UWB channel 5 (e.g., 6,240MHz–6,740MHz), UWB channel 9 (e.g., 7,740MHz–8,240MHz), and UWB channel 10 (e.g., 8,240MHz–8,740MHz) are the three main target UWB channels for UWB applications (e.g., digital key applications). In some cases, UWB digital key applications target the use of UWB channel 9, with UWB channel 5 as an alternative channel. The ability to operate UWB on multiple channels increases capability because UWB devices can use different channels to coexist without interfering with each other. Furthermore, some channels are easier to operate on than others.

[0107] Unfortunately, for UWB applications, other wireless devices and standards can also use frequencies similar to those allocated to UWB channels 5, 9, and 10. Therefore, UWB devices may be vulnerable to interference from higher-power transmitters located close to the UWB device and using the same frequency range for communication. These higher-power transmitters may include International Mobile Telecommunications (IMT) equipment, such as 4G, 5G, and / or 6G equipment, and / or devices configured to use Wi-Fi for communication.

[0108] For example, UWB channel 5 is located in the center of the 6-GHz Wi-Fi spectrum, which means there is a chance of interference between the two radios, especially in very dense Wi-Fi environments with high Wi-Fi throughput. In such cases, the resulting radio interference may lead to UWB packet loss, and in some cases, prolong the time required to perform ranging sessions on an intermittent basis (e.g., based on various simulation and empirical data).

[0109] As another example, in the IMT spectrum, frequencies between 7,125 MHz and 15,000 MHz (e.g., the frequency range 3 (FR3) band) and between 6,425 MHz and 7,125 MHz are targets for IMT wireless communication. The IMT target frequencies between 6,425 MHz and 7,125 MHz partially overlap with the frequency of UWB channel 5, while the IMT target frequencies between 7,125 MHz and 15,000 MHz overlap with both UWB channels 9 and 10. Such overlap indicates that UWB devices operating at these frequencies may be vulnerable to interference from IMT devices.

[0110] For example, Figure 6 The sensitivity of UWB-enabled devices to interference from higher-power broadband communication transmitters is depicted. As shown in the figure, a UWB-enabled UE 604 (e.g., such as...) Figure 1 and Figure 3UE 104) can simultaneously communicate with network entity 602 (e.g., such as Figure 1 and Figure 3 BS 102 or as relative to Figure 2 The UE 604 communicates with both the decomposed base station (discussed) and the vehicle configured for UWB communication (e.g., UWB device 606). More specifically, when it is determined that the UE 604 is within a threshold distance of the UWB device 606 (e.g., via coarse Bluetooth location estimation), the UE 604 can communicate with the UWB device 606 to perform a UWB ranging session with the UWB device 606. For this example, the UWB ranging session between the UE 604 and the UWB device 606 can occur on the frequency of UWB channel 9 (e.g., between 7,740 MHz and 8,240 MHz). The UE 604 can also wirelessly communicate with network entity 602 using frequencies between 7,740 MHz and 8,240 MHz. Therefore, interference with UWB communication between the UE 604 and the UWB device 606 may be unavoidable.

[0111] Figure 7 It describes the entities from the network (such as...) Figure 6 The illustrated graph 700 shows an example of interference to multiple outdoor UWB devices caused by the transmission of network entity 602. The x-axis of graph 700 corresponds to the percentage of UWB devices experiencing interference. The y-axis of graph 700 corresponds to the percentage of the cumulative distribution function (CDF) of the signal-to-noise plus-interference ratio (SNIR) perceived by the multiple UWB devices. As shown, for this example, 78% of the UWB devices may experience interference exceeding a predetermined acceptable level.

[0112] Interference caused by the coexistence of wireless telecommunications equipment and UWB equipment operating in the same frequency band is a technically challenging problem, given that such interference can lead to data loss, inefficient ranging sessions between UWB equipment, and / or adversely affect sensitive UWB equipment.

[0113] Various aspects related to the coexistence of UWB devices and wireless telecommunications equipment on the same channel

[0114] To overcome the technical challenges associated with the coexistence of wireless telecommunications equipment (e.g., 4G, 5G, and / or 6G equipment) and UWB equipment operating in the same frequency band, the aspects described herein present various techniques for mitigating channel interference. For example, one or more network entities (e.g., example wireless telecommunications equipment) may perform one or more interference mitigation processes to reduce interference in a shared frequency band used by one or more UWB devices to perform UWB ranging sessions.

[0115] In some aspects, network entities are triggered to perform such interference mitigation procedures based on signaling received from a UWB device (e.g., operating in the same frequency band as the network entity) indicating that a UWB ranging session between the UWB device and another UWB device has commenced. This scenario is... Figure 8A and Figure 8B Described in the text.

[0116] Specifically, Figure 8A and Figure 8B The process flows 800 and 850 for communication between network entity 802, UE 804 (e.g., a UWB-enabled UE), and UWB device 806 in the network are described. In some aspects, network entity 802 is relative to... Figure 1 and Figure 3 The BS 102 depicted and described or relative to Figure 2 An example of a decomposed base station is depicted and described. Similarly, UE 804 can be relative to... Figure 1 and Figure 3 Examples of UE 104 depicted and described herein. However, in other respects, UE 104 may be another type of wireless communication device, and BS 102 may be another type of network entity or network node, such as those described herein.

[0117] In some respects, the UWB device 806 is implemented within a vehicle, and the UE 804 and the UWB device 806 are configured to perform a UWB ranging session to allow the user of the UE 804 (who is also the owner of the vehicle) to unlock / lock the vehicle. In other words, UWB communication between the UE 804 and the UWB device 806 can be an example of using UWB technology for digital key applications. UWB communication between the UE 804 and the UWB device 806 (e.g., to allow digital key locking and / or unlocking) can begin when it is determined that the UE 804 is within a threshold distance of the UWB device 806.

[0118] In some other aspects, UWB device 806 is implemented in commercial buildings or residences to enable digital key control access in these locations. In some other aspects, UWB device 806 is implemented at a register to allow automatic payment for one or more items for sale via a UWB application enabled on UE 104 when UE 104 is within a threshold distance of UWB device 806. It should be noted that the described locations where UWB device 806 is implemented are merely examples, and many other locations and / or use cases not listed above can be considered to allow for a variety of UWB applications utilizing UWB device 806.

[0119] like Figure 8A and Figure 8BAs shown, process flows 800 and 850 begin at step 810, where UE 804 determines that it is within a threshold distance (e.g., within 2 meters (m) or less) of the UWB device (e.g., UWB device 806) (e.g., the distance from UE 804 to UWB device 806). In some respects, UE 804 makes this determination based on performing a coarse Bluetooth location estimate at step 808. As described above, UE 804 can use the coarse Bluetooth location estimate to estimate the approximate location of UE 804 relative to UWB device 806. Because UWB communication is a short-range wireless communication protocol, UE 804 needs to first determine that UE 804 is within a threshold distance (e.g., short range) from UWB device 806.

[0120] Based on the determination that UE 804 is within a threshold distance of UWB device 806, process flows 800 and 850 continue at step 812, whereby UE 804 initiates a UWB ranging session 814 between UE 804 and UWB device 806. As described above, the UWB ranging session 814 may involve transmitting radio power pulses between UE 804 and UWB device 806, and further performing ToF measurements between UE 804 and UWB device 806. The UWB channel used for the UWB ranging session 814 between UE 804 and UWB device 806 may be UWB channel 5 (e.g., corresponding to the 6,240MHz-6,740MHz band), UWB channel 9 (e.g., corresponding to the 7,740MHz-8,240MHz band), or UWB channel 10 (e.g., corresponding to the 8,240MHz-8,740MHz band).

[0121] The frequency of the UWB channel used for UWB ranging session 814 can also be used for other cellular communications between UE 804 and network entity 802, including 4G, 5G, 6G, and / or UE 804. As an illustrative example, UWB ranging session 814 may occur in a frequency range of 7,740MHz-8,240MHz (e.g., corresponding to UWB channel 9), and network entity 802 may communicate with UE 804 within the same frequency range.

[0122] Then, process flows 800, 850 continue at step 816, where UE 804 sends signaling (referred to herein as “first signaling”) instructing the initiation of a UWB ranging session 814 between UE 804 and UWB device 806. For example, UE 804 may send this signaling based on determining that UE 804 is within a threshold distance of UWB device 806 and / or based on initiating a UWB ranging session 814. In some aspects, UE 804 sends the signaling immediately after initiating the UWB ranging session 814 with UWB device 806.

[0123] At step 816, UE 804 may send signaling to network entity 802 to notify UE 804 that UE 804 is also participating in (or will participate in) the UWB ranging session 814 with UWB device 806. Notifying network entity 802 of the UWB ranging session 814 may trigger network entity 802 to initiate the execution of one or more interference mitigation procedures to reduce interference in the UWB channel used for the UWB ranging session 814.

[0124] For example, in response to receiving signaling at step 816, network entity 802 determines the location of UE 804 at step 818. In some aspects, network entity 802 determines the location of UE 804 based on received signaling indicating the location of UE 804. In some aspects, this signaling is sent by UE 804 to network entity 802. Network entity 802 can use the location information of UE 804 to perform one or more interference mitigation procedures. Therefore, at step 820, network entity 802 initiates the execution of such procedures. The execution of one or more interference mitigation procedures can be used to reduce interference in the UWB channel used for the UWB ranging session 814 between UE 804 and UWB device 806.

[0125] Furthermore, in some aspects, one or more interference mitigation procedures may be performed to reduce interference in UWB channels adjacent to the UWB channel used for UWB ranging session 814 between UE 804 and UWB device 806. For example, if UWB channel 9 is used for UWB ranging session 814, network entity 802 may perform one or more interference mitigation procedures within the frequency range corresponding to UWB channel 8 and / or UWB channel 10. Specifically, signals transmitted in adjacent channels may cause interference in the UWB channel used for UWB ranging session 814. For example, filters (e.g., band filters) may not attenuate all frequencies outside the desired frequency range; therefore, some energy transmitted from channels adjacent to the UWB channel used for UWB ranging session 814 may fall into the UWB channel.

[0126] The various interference mitigation processes described in detail below can be performed by network entity 802 to reduce channel interference.

[0127] For example, in some aspects, the interference mitigation process performed by network entity 802 includes configuring transmission gaps between multiple transmissions scheduled for transmission by network entity 802 to UE 804. A transmission gap refers to a period of time during which network entity 802 suppresses transmissions to UE 804. For example, a gap can be configured between each scheduled transmission, every two scheduled transmissions, every three scheduled transmissions, etc. In other words, gaps can be configured periodically between transmissions for a specific periodicity. In some aspects, gaps can be configured randomly. In some aspects where multiple gaps are configured, the gaps are configured with the same duration. In some aspects where multiple gaps are configured, fewer than all gaps are configured with the same duration.

[0128] In some aspects, network entity 802 determines to configure such transmission gaps in response to receiving a signaling request from UE 804 requesting network entity 802 to configure one or more transmission gaps. In some aspects, in the received request, UE 804 indicates the number of gaps requested to be configured by network entity 802, the duration of the one or more gaps, and / or the periodicity of the gaps.

[0129] The configuration of scheduling the intervals between transmissions from network entity 802 to UE 804 helps reduce the probability of interference in the frequency band also used for the UWB ranging session 814 between UE 804 and UWB device 806. Specifically, since network entity 802 does not transmit signals to UE 804 (such as in the direction of UE 804), interference is reduced compared to the case where such signals are transmitted to UE 804.

[0130] In some aspects, the interference mitigation process performed by network entity 802 includes reducing traffic between network entity 802 and UE 804. Reducing traffic between network entity 802 and UE 804 can help reduce the probability of transmissions between network entity 802 and UE 804 interfering with UWB signaling (e.g., pulses) of UWB ranging session 814. In some aspects, network entity 802 reduces traffic by limiting the average number of transmissions with UE 804 over a certain period of time (e.g., within the frequency range in which UWB ranging session 814 is occurring).

[0131] In some aspects, the interference mitigation process performed by network entity 802 includes changing the frequency range used for communication with UE 804 (e.g., changing the channel). For example, before initiating the execution of the interference mitigation process at step 820, network entity 802 may receive an indication of a UWB channel used for UWB ranging session 814. Network entity 802 may then determine to communicate with UE 804 on a frequency range different from the frequency range associated with the UWB channel used for UWB ranging session 814. For example, where network entity 802 receives an indication from UE 804 that UWB channel 9 (e.g., 7,740 MHz - 8,240 MHz) is being used for the UWB ranging session, network entity 802 may determine to communicate with UE 804 on a frequency associated with a UWB channel other than UWB channel 9 (e.g., communicating with UE 804 on a frequency not between 7,740 MHz and 8,240 MHz).

[0132] In some respects, the interference mitigation process performed by network entity 802 includes changing the frequency band used for communication with UE 804. For example, before initiating the execution of the interference mitigation process at step 820, network entity 802 may receive an indication of the frequency band used for UWB ranging session 814. Network entity 802 may then determine to communicate with UE 804 on a frequency band different from the frequency band used for UWB ranging session 814 (e.g., indicated by UE 804).

[0133] In some respects, the interference mitigation process performed by network entity 802 includes network entity 802 using resource blocks (RBs) of the UWB channel (e.g., associated with a frequency range) that do not overlap (e.g., in frequency) with the RBs of the UWB channel used for UWB ranging session 814.

[0134] In some respects, the interference mitigation process performed by network entity 802 includes reducing the gain at network entity 802 used for communicating with UE 804. For example, network entity 802 may reduce the amount of amplifier gain used to transmit signals to UE 804, thereby reducing the power of the signals transmitted to UE 804. Therefore, signals from network entity 802 can be received at UE 804 with reduced power, thus resulting in reduced interference from such signals.

[0135] In some aspects, the interference mitigation process performed by network entity 802 includes network entity 802 shaping its antenna beam and limiting the energy transmitted toward the determined location of UE 804 (e.g., within the frequency range associated with the UWB channel used for UWB ranging session 814). Specifically, this can create empty transmissions in the direction of UE 804.

[0136] It should be noted that the interference mitigation process described above, which can be performed by network entity 802, is only an example process, and many other processes not listed above may be considered to help reduce channel interference in the UWB channel used for UWB ranging session 814.

[0137] In some aspects, such as Figure 8A As shown, network entity 802 performs an interference mitigation process until it receives, at step 824, a signaling indicating the completion of UWB ranging session 814 (e.g., referred to herein as "second signaling"). For example, UE 804 may be configured to send the signaling indicating the completion of UWB ranging session 814 to network entity 802 after the completion of UWB ranging session 814. In response to receiving the signaling at step 824, network entity 802 may stop the execution of the interference mitigation process (e.g., at step 826).

[0138] In some other aspects, such as Figure 8B As shown, when initiating the execution of an interference mitigation procedure, network entity 802 may start a timer. In some cases, the timer is a predefined timer configured to run for a predefined amount of time. In some cases, UE 804 signals to network entity 802 the length of the timer (e.g., from start to expiration). The length of the timer provided by UE 804 may be based on the expected duration of the UWB ranging session 814. When the timer expires, network entity 802 may determine to stop the execution of the interference mitigation procedure (e.g., at step 834). Therefore, in this case, network entity 802 may not receive any additional signaling indicating the completion of the UWB ranging session 814.

[0139] In some respects, network entities (e.g., such as relative to) Figure 1 and Figure 3 The BS 102 depicted and described or relative to Figure 2 The decomposed base station (described and illustrated) can determine the initiation of one or more interference mitigation procedures for a UE that is not within a first threshold distance of the UWB device but is within a second threshold distance of another UE that is within the first threshold distance of the UWB device. For example, due to the proximity of two UEs, in some cases, transmissions to a UE that is not within the first threshold distance of the UWB device may cause interference to a UE that is within the threshold distance of the UWB device (e.g., when using a channel to perform a UWB ranging session). Therefore, in some cases, it may be beneficial to also initiate the initiation of one or more interference mitigation procedures for a UE that is not within the first threshold distance of the UWB device but is close to another UE that is within that first threshold distance.

[0140] Figure 9Example 900 is depicted, in which a second network entity 902(2) initiates the execution of an interference mitigation procedure (e.g., implemented in a vehicle) against a second UE 904(2) that is not within a first threshold distance of the UWB device 906.

[0141] For example, such as Figure 9 As shown, the first UE 904(1) (for example, relative to Figure 1 and Figure 3 Example of UE 104 described and illustrated: (1) determining that the first UE 904 (1) is within a first threshold distance of the UWB device 906; (2) initiating a UWB ranging session with the UWB device 906; and (3) sending a signal to the first network entity 902 (1) (e.g., relative to...) Figure 1 and Figure 3 The BS102 depicted and described or relative to Figure 2 The decomposed base station described and illustrated sends signaling (e.g., similar to...). Figure 8A and Figure 8B (Steps 810, 812, and 816 in the above). In response to receiving the signaling, the first network entity 902(1) may perform one or more interference mitigation procedures for the first UE 904(1) (e.g., to reduce channel interference in the UWB ranging session between the first UE 904(1) and the UWB device 906, similar to...). Figure 8A and Figure 8B Step 820 in the middle.

[0142] Furthermore, in Example 900, the second network entity 902(2) may be aware of UWB activity occurring in the area 920 where the first UE 904(1) is located (e.g., a UWB ranging session involving the first UE 904(1) is occurring). Additionally, the second network entity 902(2) may determine at 910 that the second UE 904(2) is located in the same area 920 where UWB activity is occurring (e.g., the second UE 904(2) and the first UE 904(1) are close to each other given that they are both located in the same area 920). After determining that the second UE 904(2) is in area 920, the second UE 904(2) may determine at 912 to initiate the execution of one or more interference mitigation procedures for the second UE 904(2).

[0143] In some aspects, one or more network entities may be able to identify areas / locations (e.g., referred to herein as “dense areas”) where a large number of UWB ranging sessions occur between the UE and the UWB device (e.g., the number of UWB ranging sessions exceeds a first threshold frequency, where the first threshold frequency is a threshold rate of UWB ranging sessions occurring within a certain time period). For example, one or more network entities may identify multiple UWB ranging sessions occurring at a specific parking lot, parking garage, or store that exceed the first threshold frequency. In some aspects, this information is used to create heatmaps that indicate the frequency of UWB ranging sessions at different locations.

[0144] Furthermore, in some aspects, one or more network entities can be aware of different times during which UWB ranging sessions in these densely populated areas exceed a second threshold frequency. In some cases, the first and second thresholds are the same. In other cases, the first and second thresholds are different. For example, for a parking garage, one or more network entities can determine that the number of UWB ranging sessions exceeds the second threshold frequency between 7:00 AM and 9:00 AM and between 4:00 PM and 6:00 PM (e.g., due to the use of a digital key application to unlock / lock cars, where the parking lot is an employee parking lot). This information can also be added to the created heatmap.

[0145] In some respects, one or more network entities may use heatmaps or location-based methods to determine whether to initiate one or more interference mitigation procedures. For example, if a UWB-enabled UE is identified as being in an area (e.g., a dense area where the number of known UWB ranging sessions exceeds a first threshold frequency), a network entity may initiate one or more interference mitigation procedures for that UWB-enabled UE. As another example, if a UWB-enabled UE is identified as being in an area (e.g., when the number of known UWB ranging sessions exceeds a second threshold frequency) at a certain time (e.g., at 8:00 AM), a network entity may initiate one or more interference mitigation procedures for that UWB-enabled UE. For example, by using heatmaps, network entities may be able to infer at what time of day, week, month, or year UWB ranging activity is higher and in what locations it is higher.

[0146] In some respects, the information contained in the generated heatmap can be used to train machine learning algorithms to optimize services, thereby helping to reduce channel interference for UWB applications.
