CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This patent application claims the benefit of U.S. Provisional Patent Application No. 63 / 375,482, filed on September 13, 2022, entitled “NARROWBAND ASSISTED ULTRAWIDEBAND FREQUENCY HOPPING,” and U.S. Non-Provisional Patent Application No. 18 / 463,003, filed on September 7, 2023, entitled “NARROWBAND ASSISTED ULTRAWIDEBAND FREQUENCY HOPPING,” which are incorporated herein by reference in their entirety. Technical Field

[0002] Aspects of the present disclosure generally relate to wireless communications and techniques and apparatus for narrowband-assisted ultra-wideband frequency hopping. Background Art

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that are capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).

[0004] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink communication and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a municipal, national, regional and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink, CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM) on the uplink, and supporting beamforming, Multiple Input Multiple Output (MIMO) antenna technology and carrier aggregation to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0006] Some aspects described herein relate to a method of wireless communication performed by a first wireless communication device. The method may include: sending a first synchronization message to a second wireless communication device using a first radio frequency (RF) technology and a first frequency resource, the first synchronization message being associated with synchronization of a second RF technology. The method may include: after switching to a second frequency resource different from the first frequency resource, sending a second synchronization message to the second wireless communication device using the first RF technology, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource is based at least in part on the transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or one or more of a failure of the first synchronization message or a failure of a reply to the first synchronization message from the second wireless communication device.

[0007] Some aspects described herein relate to a first wireless communication device for wireless communication. The first wireless communication device may include one or more memories and one or more processors coupled to the memory. The one or more processors may be configured, individually or collectively, to send a first synchronization message to a second wireless communication device using a first RF technology and a first frequency resource, the first synchronization message being associated with synchronization of the second RF technology. The one or more processors may be configured, individually or collectively, to send a second synchronization message to the second wireless communication device using the first RF technology after switching to a second frequency resource different from the first frequency resource, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource is based at least in part on the transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or one or more of a failure of the first synchronization message or a failure of a reply to the first synchronization message from the second wireless communication device.

[0008] Some aspects described herein relate to a non-transitory computer-readable medium storing a set of instructions for wireless communication by a first wireless communication device. The set of instructions, when executed by one or more processors of the first wireless communication device, can cause the first wireless communication device to send a first synchronization message to a second wireless communication device using a first RF technology and a first frequency resource, the first synchronization message being associated with synchronization of a second RF technology. The set of instructions, when executed by one or more processors of the first wireless communication device, can cause the first wireless communication device to: after switching to a second frequency resource different from the first frequency resource, send a second synchronization message to the second wireless communication device using the first RF technology, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource is based at least in part on the transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or one or more of a failure of the first synchronization message or a failure of a reply to the first synchronization message from the second wireless communication device.

[0009] Some aspects described herein relate to an apparatus for wireless communication. The apparatus may include components for sending a first synchronization message to a second wireless communication device using a first RF technology and a first frequency resource, the first synchronization message being associated with synchronization of the second RF technology. The apparatus may include components for sending a second synchronization message to the second wireless communication device using the first RF technology after switching to a second frequency resource different from the first frequency resource, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource is based at least in part on one or more of transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or a failure of the first synchronization message or a failure of a reply to the first synchronization message from the second wireless communication device.

[0023] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. And these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of various aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method that uses other structures, functions, or structures and functions practiced in addition to or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0024] Several aspects of the telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in the detailed description below and will be illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0025] Although various aspects may be described herein using terminology generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RAT (e.g., 6G).

[0026] Figure 1 1 is a diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be an aggregated network node, which means that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes, such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs).

[0027] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link (such as an RU). In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link (such as a DU). In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmission reception point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network device, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 using any suitable transport network through various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0028] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of ​​the network node 110 and / or a network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a micro cell, a femto cell, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) and may allow unrestricted access to UEs 120 with service subscriptions. A micro cell may cover a relatively small geographic area and may allow unrestricted access to UEs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs 120 associated with a femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 of a macro cell may be referred to as a macro network node. A network node 110 of a micro cell may be referred to as a micro network node. The network node 110 of a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0029] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near-real-time (Near-Real Time, near RT) RAN intelligent controller (RIC), or a non-real-time (Non-Real Time, non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as the functions described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographical location or in different geographical locations) may be configured to perform at least a portion of a function, or to replicate the execution of at least a portion of a function, and the term "base station" or "network node" may refer to any one or more of those different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not another. In this way, a single device may include more than one base station.

[0030] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and send transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1In the example shown in , a network node 110d (e.g., a relay network node) can communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0031] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 to 40 Watts), while a pico network node, a femto network node, and a relay network node may have a low transmit power level (e.g., 0.1 to 2 Watts).

[0032] The network controller 130 may be coupled to or communicate with a group of network nodes 110 and may provide coordination and control for these network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may communicate with each other directly or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0033] UE 120 may be dispersed in wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0034] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with other devices (e.g., remote devices) of network nodes or certain other entities. Some UEs 120 may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment (Customer Premises Equipment). UE 120 may be included in a housing that houses components of UE 120 (such as processor components and / or memory components). In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., one or more memories) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0035] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0036] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary for communicating with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, or vehicle-to-pedestrian (V2P) protocol), and / or mesh network. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0037] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, etc. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a "sub-6 GHz" band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, although unlike the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as a "millimeter wave" band by the International Telecommunications Union (ITU), FR2 is often referred to (interchangeably) as a "millimeter wave" band in documents and articles.

[0038] Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR research has identified operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). Frequency bands that fall within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and may therefore effectively extend the characteristics of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band.

[0039] With the above examples in mind, unless otherwise specifically stated, it should be understood that the term "sub-6 GHz" and the like, if used herein, can broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like, if used herein, can broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or may be within the EHF band. The frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are expected to be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0040] In some aspects, the first wireless communication device described herein may correspond to and / or may be associated with UE 120 or network node 110. In some aspects, the first wireless communication device may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 or 150 may send a first synchronization message to a second wireless communication device using a first radio frequency (RF) technology and a first frequency resource, the first synchronization message being associated with synchronization of a second RF technology; and after switching to a second frequency resource different from the first frequency resource, send a second synchronization message to the second wireless communication device using the first RF technology, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource is based at least in part on one or more of transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or a failure of the first synchronization message or a failure of a reply to the first synchronization message from the second wireless communication device. Additionally or alternatively, the communication manager 140 or 150 may perform one or more other operations described herein.

[0041] As mentioned above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0042] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or other components that facilitate communication with the UE 120 or other network nodes. Some network nodes 110 may not include radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs, or one or more DUs.

[0043] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0044] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110, and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0045] The network controller 130 may include a communication unit 294, a controller / processor 290, and one or more memories 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0046] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or be coupled to one or more transmit and / or receive components (such as antennas). Figure 2 One or more antenna elements of one or more components).

[0047] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by a modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figure 6-Figure 9 )

[0048] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by an antenna 234, processed by a modem 232 (e.g., a demodulator component of the modem 232, shown as DEMOD), detected by a MIMO detector 236 (if applicable), and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figure 6-Figure 9 )

[0049] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the network node 110 may perform one or more techniques associated with narrowband-assisted ultra-wideband frequency hopping, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 8 800 and / or other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 8 The process 800 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0050] In some aspects, a first wireless communication device includes: a component for sending a first synchronization message to a second wireless communication device using a first RF technology and a first frequency resource, the first synchronization message being associated with synchronization of the second RF technology; and / or a component for sending a second synchronization message to the second wireless communication device using the first RF technology after switching to a second frequency resource different from the first frequency resource, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource is based at least in part on transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or one or more of a failure of the first synchronization message or a failure of a reply to the first synchronization message from the second wireless communication device.

[0051] In some aspects, means for the first wireless communication device to perform the operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246. In some aspects, means for the first wireless communication device to perform the operations described herein may include, for example, the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, the memory 282, the scheduler 246, or the scheduler 246. Figure 3 The ultra-wideband transceiver 305 described herein, combined with Figure 3 The narrowband transceiver 320 described, and / or in combination Figure 3 One or more of the processors 335 described.

[0052] Although Figure 2 The blocks in the 200 and 210 are shown as distinct components, but the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0053] As mentioned above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0054] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station, or a network device can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP, or a cell, etc.) or one or more units (or one or more components) performing base station functions can be implemented as an aggregated base station (also called an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "network node" may refer to a decomposed base station, or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0055] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed throughout one or more other network nodes. The DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), etc.

[0056] Base station type operation or network design may take into account the aggregated nature of base station functions. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration sponsored by the O-RAN Alliance)) or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate expansion of the communication system by dividing the base station functions into one or more units that can be deployed separately. The decomposed base station may include functions implemented across two or more units at various physical locations, as well as functions implemented virtually for at least one unit, which may enable flexibility in network design. The various units of the decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0057] Figure 3 3 is a diagram illustrating an example 300 of RF components of a UE 120 according to the present disclosure. Although for convenience, the UE 120 is described in the context of Figure 3 However, the aspects of the present disclosure are not limited thereto. In other aspects, in combination with Figure 3 Certain features and components of the described UE 120 may be incorporated into other wireless communication devices (eg, UWB devices) without departing from the scope of the present disclosure.

[0058] In some cases, UE 120 may be equipped with multiple transceivers capable of operating various RF technologies. Figure 2In addition to the transceiver components described (which, in some cases, can be used to communicate over the wireless network 100, as described), the UE 120 can also be equipped with additional transceivers or similar components, such as transceivers associated with short-range wireless communication technologies. Short-range wireless communication enables wireless communication over relatively short distances (e.g., within 30 meters). The Bluetooth protocol is an example of a wireless technology standard for exchanging data over short distances using short-wavelength ultra high frequency (UHF) radio waves from 2.4 gigahertz (GHz) to 2.485 GHz. The Bluetooth Low Energy (BLE) protocol is for communication with devices that operate on low power. Various other short-range wireless communication technologies can operate at similar wavelengths, such as wireless local area network (WLAN) technology, Zigbee, and ultra-wideband (UWB) technology, which are described in more detail below. In some aspects, technologies such as Bluetooth, BLE, WLAN, Zigbee, etc. may operate using relatively narrow frequency bands compared to UWB technologies, and thus may be collectively referred to as narrowband (NB) technologies.

[0059] like Figure 3 As shown, in some cases, UE 120 may include components for communicating using one or more short-range wireless communication technologies. For example, UE 120 may include UWB components such as Figure 3 305 or related components shown in . In some cases, the UWB transceiver 305 may include various components that enable UWB communication, such as a UWB signal generator / processor 310 and / or a UWB antenna or antenna array 315. As shown, the UWB signal generator / processor 310 and the UWB antenna or antenna array 315 can communicate with each other (e.g., via one or more buses and / or one or more other components).

[0060] One or more of the UWB transceiver 305, the UWB signal generator / processor 310, and the UWB antenna or antenna array 315 may enable a UWB connection. A UWB connection is a short-range wireless communication protocol that operates at a very high frequency compared to other short-range wireless communication technologies (e.g., Bluetooth, WLAN, Zigbee, etc.), and uses a relatively wide frequency band (e.g., 500 MHz or greater) compared to other short-range wireless communication technologies, which makes UWB useful for high-resolution positioning and location purposes. In some cases, UWB technology may be used for location discovery, device ranging, and the like. In some cases, a UWB transmitter (e.g., a UWB transceiver 305) may transmit many pulses across a wide spectrum of frequencies, and a corresponding UWB receiver (e.g., a UWB transceiver 305 located at another UWB-enabled device) may convert the pulses into data by listening to the familiar pulse trains transmitted by the transmitter.

[0061] When multiple UWB devices are close to each other (e.g., when two UEs 120 including UWB components such as UWB transceivers 305 are close to each other), the two UWB devices may begin ranging or measuring the distance from each other. In this case, the first UWB device (e.g., the UWB that first sends a UWB communication, sometimes referred to as a ranging measurement signal and / or a UWB measurement signal) may be referred to as an initiator, and the second UWB device may be referred to as a responder. In some cases, measuring the distance between two UWB devices may be referred to as two-way ranging (TWR) because the measurement relies on two-way communication between the two UWB devices. More specifically, in TWR, the initiator and responder may measure the distance between each other using time-of-flight (TOF) measurements, etc. (such as by multiplying the round-trip time of the signal by the speed of light and dividing by 2). In some aspects, UWB devices may be able to determine the relative position of peer devices with a line of sight of up to 200 meters or similar distances. In some aspects, by additionally measuring the distance between the UWB device and a fixed beacon or anchor and then using triangulation, the UWB device may be able to perform two-dimensional or three-dimensional positioning. In some cases, "TWR" may refer to a single-sided TWR or a double-sided TWR. "Single-sided TWR" may refer to a TWR based on two messages or a set of messages sent between an initiator and a responder (e.g., a poll message or a set of poll messages sent from an initiator to a responder, and a reply message or a set of reply messages sent from a responder to an initiator), while "double-sided TWR" may refer to a TWR based on three or more messages or a set of messages sent between an initiator and a responder (e.g., the poll and reply messages described above in addition to a final message or a set of final messages sent from an initiator to a responder, and optionally, a report message or a set of report messages sent from a responder to an initiator).

[0062] Back to Figure 3 , UE 120 may include additional transceivers or components, such as additional transceivers associated with different short-range wireless communication protocols. For example, UE 120 may include NB components (such as Figure 3 ) or related components. In some cases, the NB transceiver 320 may include various components that enable NB connections, such as a NB signal generator / processor 325 and / or a NB antenna or antenna array 330. As shown, the NB signal generator / processor 325 and the NB antenna or antenna array 330 may communicate with each other. In some cases, the NB transceiver 320 and / or other NB components of the UE 120 may be associated with one or more of a Bluetooth connection, a BLE connection, a WLAN connection, a Zigbee connection, etc., which may use a relatively narrow frequency band compared to a UWB connection and / or may operate in a relatively low frequency range compared to a UWB connection.

[0063] In some cases, UWB components (e.g., UWB transceiver 305) and / or NB components (e.g., NB transceiver 320) can communicate with each other or otherwise coexist with each other. For example, in some cases, UWB transceiver 305 and / or NB transceiver 320 can be connected to processor 335. Processor 335 can control certain functions of UWB transceiver 305 and / or NB transceiver 320, including, in some cases, operating UWB transceiver 305 and / or NB transceiver 320 in conjunction with each other. For example, in some cases, processor 335 can control UWB transceiver 305 and / or NB transceiver 320 for the purpose of performing NB-assisted (NBA) UWB (NBA-UWB) technology (such as the NBA-UWB technology described below).

[0064] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different than described.

[0065] Figure 4 is a diagram illustrating an example 400 of a UWB packet structure and a multi-millisecond NB-assisted UWB packet structure according to the present disclosure.

[0066] As combined Figure 4As described, in some cases, UE 120 or other UWB devices may send UWB packets between each other for the purpose of estimating the range (or distance) between the devices, or for other purposes such as estimating the angular direction in which the stations appear relative to each other. UE 120 or other UWB devices may also send UWB packets to exchange payload data between each other.

[0067] Like many other wireless communication systems (eg, WLAN, Bluetooth, or cellular services), UWB transmissions follow certain physical layer (PHY) frame formats or packet formats (the terms "packet" and "frame" are used interchangeably herein). Figure 4 An example packet format for UWB transmission is shown. More specifically, the UWB device may use a no-data (ND) packet structure as shown at reference numeral 405, an NBA-UWB packet structure as shown at reference numeral 410, an NBA multi-millisecond UWB packet structure as shown at reference numeral 415, or other similar packet structures.

[0068] The ND packet structure may include a preamble 420, a start of frame delimiter (SFD) 425, and / or a scrambled timestamp sequence (STS) 430. In some aspects, the ND packet structure may be used to synchronize time and / or frequency between two UWB devices. For example, a first UWB device (e.g., an initiator) may send an ND packet, and other UWB devices (e.g., responders) may listen for the preamble 420. Once the preamble 420 is detected, the responder may listen for the SFD 425. The responder may use the SFD 425 to acquire frame timing. For example, a UWB packet may be sent by the initiator UWB at time 0, and thus the responder UWB device may timestamp the arrival of the UWB packet (e.g., the arrival of the preamble 420 and / or the SFD 425) as time 0. In addition, the responder may listen for the STS 430, which in some cases may be used for channel estimation and / or for the purpose of timestamp verification for secure TOF-based distance estimation, etc. In some cases, the preamble 420 may be alternatively referred to as a ranging preamble or a synchronization component (SYNC), and / or the preamble 420 and SFD 425 (and optionally, the STS 430, if equipped) may be collectively referred to as a synchronization header (SHR). By receiving the preamble 420, SFD 425, or / and STS 430, the responder UWB device may synchronize time and / or frequency with the initiator UWB device, and thus receive the UWB transmission (e.g., the preamble 420) for the purpose of TWR or other purposes.

[0069] In other cases, one or more UWB devices may be synchronized based on other RF technologies, such as NB technology. In some cases, this may be referred to as NBA-UWB. Reference numeral 410 indicates an example of an NBA-UWB packet structure. In this example, NB packet 435 provides time and / or frequency synchronization information for a UWB packet, such as time and / or frequency synchronization information for a UWB measurement signal 440 (e.g., a UWB preamble or similar measurement signal). More specifically, a NB component associated with an initiator device (e.g., in conjunction with Figure 3 The NB transceiver 320 described above may send a NB packet 435, which in some cases may be used to provide initial time and / or frequency synchronization for subsequent UWB transmissions. Figure 4As shown in , in some cases, the initiator may send a NB packet 435 before time 0, and then send a UWB measurement signal 440 at time 0 (which in some cases may be just a ranging preamble (e.g., preamble 420) without SFD 425 and / or STS 430). The responder UWB device may receive the NB packet 435 and synchronize time and / or frequency accordingly to correctly receive the UWB measurement signal 440 at time 0. Time and frequency may be further synchronized using UWB communication.

[0070] In other cases, multiple UWB transmissions may be synchronized and / or scheduled according to other RF technologies, such as NB technologies. For example, in some cases, NB packet 435 may synchronize and / or schedule multiple UWB transmissions that span more than one millisecond, and thus may be referred to as NBA multi-millisecond UWB. Reference numeral 415 indicates an example of an NBA multi-millisecond UWB packet structure. In this example, NB packet 435 provides time and / or frequency synchronization information for multiple UWB packets, such as multiple UWB measurement signal 440 transmissions. More specifically, a NB component associated with an initiator device (e.g., in conjunction with Figure 3 4. The NB transceiver 320 described above may send a NB packet 435, which in some cases may include time and / or frequency synchronization information for multiple subsequent UWB transmissions. In other words, the NB component shares a clock source with the UWB component. In some cases, the initial synchronization process (e.g., establishing and providing initial timing and frequency synchronization for UWB measurements) may be referred to as Phase I or Phase 1.

[0071] like Figure 4As shown, the initiator may send a NB packet 435 before time 0 and then send a first UWB measurement signal 440 at time 0 (which may be only the preamble 420 without the SFD 425 and / or STS 430 in some cases). The initiator UWB may send additional packets (e.g., UWB measurement signals 440) at given time intervals so that UWB measurements may be performed over a longer duration (e.g., multiple milliseconds) than the structure described in conjunction with reference numerals 405 and 410. In some cases, each UWB packet and / or transmission may be referred to as a segment. For purposes of link budget gain, etc., multiple one-millisecond segments may enable combination. The responder UWB device may receive the NB packet 435 and synchronize time and / or frequency accordingly so as to appropriately receive multiple UWB measurement signals 440 at time 0, time 1, time 2, etc. In some cases, the UWB measurement signals 440 may be measured for the purpose of ranging procedures. Measurement of UWB segments using a UWB connection may be referred to as Phase II or Phase 2. In some cases, the responder UWB device may send a measurement report to the initiator UWB device indicating the measurements performed during Phase II. The measurement report may be sent using the same RF connection as Phase I (e.g., the same NB connection used to send NB packet 435). In some cases, sending the measurement report may be referred to as Phase III or Phase 3.

[0072] In some cases, the NB technology used to send NB packet 435 may be associated with an unlicensed National Information Infrastructure (UNII) radio frequency band, such as the UNII-3 band (e.g., a band associated with a frequency range of 5.725 to 5.850 GHz and a bandwidth of 125 MHz) or other UNII bands (e.g., UNII-5 (5.925 to 6.425 GHz frequency range and 500 MHz bandwidth), UNII-6 (6.425 to 6.525 GHz frequency range and 100 MHz bandwidth), UNII-7 (6.525 to 6.875 GHz frequency range and 350 MHz bandwidth), and / or UNII-8 (6.875 to 7.125 GHz frequency range and 250 MHz bandwidth)). Additionally or alternatively, the NB technology used to transmit the NB packet 435 may be associated with WLAN, Bluetooth, BLE, and / or offset quadrature phase-shift keying (O-QPSK) technology such as Zigbee, or the like.

[0073] In some networks, utilizing NB technology for time and / or frequency synchronization purposes (e.g., utilizing one of the NBA-UWB packet structures described above) may result in certain benefits compared to the UWB packet structure, such as enabling frequency hopping and / or enabling the use of higher transmission power (e.g., higher transmission power per Hz) than UWB (e.g., 14 dBm) to transmit the initial packet (e.g., NB packet 435), which may be useful for range extension purposes, etc. In addition, multiple one millisecond segments may enable combining for link budget gain purposes, etc., while using NB technology for clock synchronization purposes may reduce overhead on the UWB spectrum, thereby increasing transmission opportunities and improving ranging capabilities. However, NBA-UWB technology has not yet been adapted for use for TWR purposes, and therefore their application is limited.

[0074] Some techniques and apparatus described herein enable the use of NBA-UWB technology for TWR purposes, enable the use of higher transmission power than UWB to transmit initial synchronization packets, enable the combination of multiple one millisecond segments for the purpose of link budget gain in TWR, and reduce the overhead on the UWB spectrum in TWR, thereby increasing transmission opportunities and improving TWR capabilities. Figure 5-1 1 describes various aspects of using NBA-UWB technology for the purpose of TWR.

[0075] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0076] Figure 5 An example 500 of a UWB ranging session 505 according to the present disclosure is shown. In some examples, NB technology (such as BLE) can be used for discovery purposes and to establish the UWB ranging session 505 shown in example 500. This can include using a NB connection (e.g., a BLE connection) to select a UWB channel to use, to configure ranging slots, rounds and block durations, etc. More specifically, in some examples, the UWB ranging session 505 can include one or more ranging blocks 510, wherein each ranging block 510 includes one or more ranging rounds 515, and wherein each ranging round 515 includes one or more ranging slots 520. In some examples, the UWB ranging session 505 can be configured such that each ranging round 515 includes one UWB measurement, and / or each ranging block 510 includes one ranging round 515. Furthermore, ranging block 510, ranging round 515 and / or ranging slot 520 durations may be configured such that each ranging slot 520 is long enough to complete one UWB message and such that the number of ranging slots 520 per ranging round 515 is large enough to complete one ranging measurement.

[0077] In some examples, the NB connection can be used to synchronize the start time of the ranging session 505. For example, the NB connection or a component associated with the NB connection can pass a time parameter (sometimes referred to as UWB_Time_T0, as shown in reference numeral 525) to the UWB connection or a component associated with the UWB connection to mark the start of the ranging session 505. In some examples, the duration of each ranging block 510 can determine the frequency of the ranging measurement. For example, one single-sided TWR measurement can be completed per ranging block 510, and thus shorter duration ranging blocks 510 can result in more frequent TWR measurements, while longer duration ranging blocks 510 can result in less frequent TWR measurements. In addition, in some examples, round hopping can be configured so that the index of the ranging wheel 515 changes from one ranging block 510 to the next ranging block 510. For example, when round hopping is enabled, the wheel index can be selected in each ranging block 510 based at least in part on a specified round hopping function.

[0078] In some aspects described herein, a first wireless communication device (e.g., UE or network node) may send a first synchronization message to a second wireless communication device (e.g., UE or network node) using a first RF technology (e.g., NB technology) and a first frequency resource. The first synchronization message may be associated with synchronization of a second RF technology (e.g., UWB technology). For example, the first synchronization message may be part of NBA-UWB technology. The first wireless communication device may switch to a second frequency resource and subsequently send a second synchronization message (also associated with synchronization of the second technology) using the first RF technology and on the second frequency resource.

[0079] In some aspects, the first wireless communication device may switch to a second frequency resource to send a second synchronization message (e.g., after a first synchronization message) within a time slot, round, or block associated with ranging or sensing based at least in part on the second synchronization message. For example, the first wireless communication device may be configured to switch frequency resources (e.g., frequency hopping) after each time slot, round, or block (e.g., regardless of whether the previous synchronization message was successful). In some aspects, the first wireless communication device may be configured (e.g., based at least in part on previous communications and / or communication protocols, etc.) to switch frequency resources at each ranging block (e.g., one or more rounds), each ranging round (e.g., one or more time slots and a full or partial round), or each ranging time slot. In this way, if the switch is conditional (e.g., conditional on the failure of the first synchronization message), the first wireless communication device can save computing and power resources that would otherwise be used.

[0080] In some aspects, the first wireless communication device may switch to the second frequency resource to send the second synchronization message based at least in part on the failure of the first synchronization message. For example, the failure of the first synchronization message may include the failure of the second wireless communication device to receive the synchronization message, the failure of the first wireless communication device to receive a reply to the first synchronization message, and / or the busyness of the channel associated with the first frequency resource (e.g., interference and / or resources occupied by other signaling), etc. In this way, the first wireless communication device can save network resources by not forcing unnecessary hopping.

[0081] For example, if the first synchronization message and the reply to the first synchronization message are successful, the first wireless communication device does not apply hopping. If the second wireless communication device does not successfully receive the first synchronization message (e.g., the first NB message), the first wireless communication device may not send the second RF technology segment associated with synchronization using the second RF technology, and / or the first wireless communication device may switch to the second frequency resource before sending the second synchronization message. If the second wireless communication device successfully receives the first synchronization message (e.g., the first NB message), but the first wireless communication device does not successfully receive the reply (e.g., the second NB message), the first wireless communication device may not send the second RF technology segment associated with synchronization using the second RF technology, and / or the first wireless communication device may switch to the second frequency resource before sending the second synchronization message. For example, the first wireless communication device may wait for the next block, round, or time slot to send the second synchronization message. At the next block, round, or time slot, the first wireless communication device may apply channel hopping (e.g., NB channel hopping) and resend the first synchronization message until the first wireless communication device receives a reply to the successfully received synchronization message via the first RF technology.

[0082] In some aspects, frequency resources may be associated with priorities. For example, frequency resources may be associated with different channels of a first RF technology. In order to reduce interference to other wireless communications (e.g., Wi-Fi), a priority channel list of the first technology (e.g., a NB priority channel list) may be defined (e.g., in UNII-3 for NBA-UWB). In the context of the present application, Wi-Fi may be a term used interchangeably with IEEE 802.11 wireless communication technology.

[0083] In some aspects (e.g., if UNII-3 is used), the selection of frequency resources and / or associated channels can involve a priority channel list. For example, the first wireless communication device can select a random channel from the priority channel list for a first attempt to send a synchronization message. Example priority channels can include frequency resources within 5730-5735 MHz and / or frequency resources within 5725-5730 MHz (e.g., a portion of Ch#144). If the first synchronization message is successful, the wireless communication device can remain in the same frequency channel (e.g., using the first frequency resource).

[0084] If the first synchronization fails (e.g., the second wireless communication device fails to receive the synchronization message and / or the first wireless communication device fails to receive a reply to the first synchronization message), the first wireless communication device may switch to a non-priority channel list to select a second frequency resource for transmission of a second synchronization message. If the second synchronization message fails, the first wireless communication device may select a third frequency resource (e.g., the same as or different from the first frequency resource) to send a third synchronization message. In this configuration, the first wireless communication device may use a non-priority channel only if transmission via a priority channel fails.

[0085] In some aspects, the distance in the frequency domain between the first frequency resource and the second frequency resource can satisfy a minimum frequency hopping distance. For example, the minimum frequency hopping distance can be used to avoid interference and improve channel diversity in the first RF technology.

[0086] In some aspects, the minimum frequency hopping distance may be based at least in part on a minimum distance for achieving diversity in the first RF technology (e.g., at least 5 MHz spacing). In some aspects, the minimum frequency hopping distance may be based at least in part on a minimum distance for reducing the likelihood of interference from signals of a third RF technology (e.g., Wi-Fi), such as the bandwidth of a channel of the third RF technology (e.g., at least 20 MHz spacing). In some aspects, the distance in the frequency domain between the first frequency resource and the second frequency resource may be selected using a pseudo-random number generator (e.g., AES or LFSR) to assist in the selection of the frequency resource (e.g., utilizing a parameter of the minimum frequency hopping distance).

[0087] In some aspects, the first wireless communication device may use a function (e.g., a recursive function) to select a next frequency resource for sending a synchronization message via the first RF technology. For example:

[0088]

[0089] where the hopping distance is d(n) = r(n) + B mod M (where M is the total number of channels in the unblocked list), B is a fixed gap (in terms of channel numbers) to ensure a minimum hopping distance, r(n) is the output of a pseudo-random number generator such as an LFSR or AES-128, and N represents a time index.

[0090] In some aspects, the minimum frequency hopping distance may be based at least in part on an equation for a channel list (e.g., a Wi-Fi channel list) for a third RF technology. Based at least in part on the failure of the first synchronization message, the first wireless communication device may generate a random number using a pseudo-random number generator, and then check whether adding the random number to the first frequency resource will keep the second frequency resource within the same frequency channel of the third RF technology as the first frequency resource. If the second frequency resource will be in the same frequency channel of the third RF technology, the second frequency resource is invalid, and the first wireless communication device attempts to select the second frequency resource again until the second frequency resource is outside the same frequency channel of the third RF technology.

[0091] Based at least in part on using the minimum frequency hopping distance, subsequent synchronization messages can be sent outside of a channel bandwidth of a third RF technology (eg, Wi-Fi), and the subsequent synchronization messages can avoid interference with the third RF technology.

[0092] Figure 6 6 is a diagram of an example 600 associated with narrowband-assisted ultra-wideband frequency hopping according to the present disclosure. Figure 6 As shown in , a first wireless communication device (WCD) (e.g., UE 120, network node 110, CU, DU, and / or RU) can transmit signals with a second wireless communication device (e.g., UE 120, network node 110, CU, DU, and / or RU). In some aspects, the first wireless communication device and the second wireless communication device can be part of a wireless network (e.g., wireless network 100) using a first RF technology (e.g., NB assisted with UWB) and / or a second RF technology (e.g., UWB).

[0093] As indicated by reference numeral 605, the first wireless communication device and the second wireless communication device may exchange configuration information. In some aspects, the first wireless communication device may send one or more portions of the configuration information to the second wireless communication device. In some aspects, the second wireless communication device may send one or more portions of the configuration information to the first wireless communication device. In some aspects, the first wireless communication device and the second wireless communication device may exchange configuration information using a sidelink communication channel, a Uu communication channel, or an indirect communication channel (e.g., communication routed through another device), etc.

[0094] In some aspects, the configuration information may indicate a pseudo-random number generator, a starting position of the pseudo-random number generator, and / or a key for generating a hopping distance using the pseudo-random number generator and / or one or more other parameters for selecting a frequency resource for sending a synchronization message via a first RF technology (e.g., NB technology). In some aspects, the configuration information may indicate a minimum hopping distance to be used when switching between a first frequency resource and a second frequency resource to send a second synchronization message, or one or more parameters for deriving the minimum hopping distance.

[0095] The first wireless communication device and the second wireless communication device may configure themselves based at least in part on the configuration information.In some aspects, the first wireless communication device and the second wireless communication device may be configured to perform one or more operations described herein based at least in part on the configuration information.

[0096] As shown in reference numeral 610, the first wireless communication device may send a first synchronization message using a first RF technology (e.g., NB technology) and a first frequency resource, and the second wireless communication device may attempt to receive the first synchronization message using the first RF technology (e.g., NB technology) and the first frequency resource. In some aspects, the first synchronization message is associated with synchronization of a second RF technology (e.g., UWB). In some aspects, the first synchronization message may be included in a control message and / or may include control information.

[0097] In some aspects, the first wireless communication device may send the first synchronization message using the first frequency resource based at least in part on a priority of the first frequency resource. For example, the first wireless communication device may send the first synchronization message using the first frequency resource based at least in part on a priority of the first frequency resource for frequency selection and / or frequency hopping using the first RF technology for synchronization of the second RF technology and / or a priority of other frequency resources (e.g., lower priority or non-priority frequency resources).

[0098] As shown at reference numeral 615, the first wireless communication device may attempt to receive a reply to the first synchronization message, and the second wireless communication device may receive a reply to the first synchronization message. For example, the second wireless communication device may send a reply to the first synchronization message based at least in part on successfully receiving the first synchronization message.

[0099] As indicated by reference numeral 620, the first wireless communication device may select a second frequency resource. For example, the first wireless communication device may select the second frequency resource based at least in part on the failure of the first synchronization message and / or based at least in part on the start of a new time domain resource (e.g., a time slot, round, or block, etc.). In some aspects, the first wireless communication device may select the second frequency resource only if the first synchronization message fails. In some aspects, the first wireless communication device may select the second frequency resource based at least in part on the start of a new time domain resource (e.g., regardless of whether the first synchronization message fails). In some aspects, the first wireless communication device may select the second frequency resource only if the first synchronization message fails, and may wait until a subsequent time domain resource starts.

[0100] In some aspects, the first wireless communication device may select a second frequency resource for sending a second synchronization message based at least in part on a priority of a first frequency resource and / or a priority of a second frequency resource within a list of priority frequency resources for frequency hopping using the first RF technology for synchronization with the second RF technology. For example, the first frequency resource may be a prioritized frequency resource and the second frequency resource may be a non-prioritized frequency resource, so the wireless communication device first attempts to send the first synchronization message on the first frequency resource and then attempts to send the second message on the second frequency resource after failing on the first frequency resource.

[0101] Alternatively, the second frequency resource may be a priority frequency resource, the first frequency resource may be a non-priority frequency resource, and the transmission of the first synchronization message on the first frequency resource is based at least in part on the failure of a previous synchronization message on an additional priority frequency resource (e.g., a frequency resource of the same or different priority as the second frequency resource). In this example, the wireless communication device may return to the priority frequency resource (e.g., the second frequency resource) after failing on the non-priority frequency resource.

[0102] In some aspects, the priority of the first frequency resource or the priority of the second frequency resource is based at least in part on the possibility of interference from wireless signaling of the third RF technology. For example, the first frequency resource or the second frequency resource can have a priority based at least in part on the possibility that a signal (e.g., from other RF technologies such as Wi-Fi) can interfere with the frequency resource. Specifically, a frequency resource located outside of a channel of the third RF resource can be a priority frequency resource.

[0103] In some aspects, the first wireless communication device may select the second frequency resource based at least in part on a minimum frequency hopping distance, a pseudo-randomly appended frequency hopping distance, or a modulo operation (e.g., to avoid selecting a frequency resource outside of an available spectrum of the first RF technology). In some aspects, the minimum frequency hopping distance is based at least in part on a minimum frequency diversity distance associated with a width of the first frequency resource and / or a minimum interference distance associated with a channel resource width of a third RF technology (e.g., Wi-Fi).

[0104] In some aspects, the first wireless communication device may select a second frequency based at least in part on generating a first random number as a temporary frequency hopping distance from the first frequency resource, wherein the temporary value of the second frequency resource is based at least in part on the first frequency resource and the temporary frequency hopping distance (e.g., the frequency hopping distance is added or subtracted from the first frequency resource). The first wireless communication device may determine whether the temporary value of the second frequency resource is within the same frequency channel of a third RF technology (e.g., Wi-Fi) and / or whether the second frequency resource meets the minimum frequency hopping distance. In some aspects, the first wireless communication device may generate a second random number as a replacement for the first random number based at least in part on the temporary value of the second frequency resource being within the same frequency channel of the third RF technology and / or failing to meet the minimum frequency hopping distance from the first frequency resource.

[0105] The first wireless communication device may switch to the second frequency resource, as indicated by reference numeral 625. For example, the first wireless communication device may configure a transmission chain for transmission using the second frequency resource and / or may tune to the second frequency resource.

[0106] In some aspects, the second wireless communication device may perform operations in parallel with the operations described in conjunction with reference numerals 620 and / or 625 to determine a second frequency resource at which the second wireless communication device may receive a second synchronization message.

[0107] As shown in reference numeral 630, the first wireless communication device may send a second synchronization message using the first RF technology and the second frequency resource, and the second wireless communication device may receive the second synchronization message using the first RF technology and the second frequency resource. In some aspects, the first wireless communication device may send the second wireless communication device message after switching to the second frequency resource (e.g., different from the first frequency resource). The second synchronization message may also be associated with synchronization of the second RF technology.

[0108] In some aspects, the first wireless communication device may send the second synchronization message using the second frequency resource based at least in part on the transmission of the second synchronization message within (e.g., having time resources within) a subsequent time slot, a subsequent round, or a subsequent block from the first synchronization message. In some aspects, the first wireless communication device and the second wireless communication device may agree on whether to switch frequency resources after each time slot, each round, or each block.

[0109] In some aspects, the first wireless communication device may send the second synchronization message using the second frequency resource based at least in part on the failure of the first synchronization message or the failure of the reply to the first synchronization message from the second wireless communication device. For example, the first wireless communication device switches to the second frequency resource only when the first synchronization message or the reply to the first synchronization message fails. Additionally or alternatively, the first wireless communication device and the second wireless communication device may agree on the switching timing (e.g., when the wireless communication device may switch frequency resources based at least in part on the failure of a previous synchronization message) after each time slot, each round, or each block.

[0110] As shown at 635, the second wireless communication device may send a reply to the second synchronization message, and the first wireless communication device may attempt to receive a reply to the second synchronization message. For example, the second wireless communication device may send a reply to the second synchronization message based at least in part on successfully receiving the second synchronization message.

[0111] Based at least in part on the success of the first synchronization message or the second synchronization message, the first wireless communication device may send one or more additional synchronization messages to the second wireless communication device using a second technology (e.g., UWB). For example, the first wireless communication device may send a preamble 420, an SFD 425, and / or a UWB measurement signal 440 to the second wireless communication device.

[0112] Based at least in part on using the minimum frequency hopping distance, subsequent synchronization messages can be sent outside the channel bandwidth of the third RF technology (e.g., Wi-Fi), and subsequent synchronization messages can avoid interference with the third RF technology. Additionally or alternatively, based at least in part on switching frequency resources after each block, round, or time slot, the first wireless communication device and the second wireless communication device can save power and / or computing resources that might otherwise be used to determine whether to switch frequency resources. Alternatively, switching only after a previous synchronization message fails can save network resources that might otherwise have been used to switch frequency resources after each block, round, or time slot.

[0113] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0114] Figure 7 is a diagram of an example 700 associated with narrowband-assisted ultra-wideband frequency hopping according to the present disclosure. Figure 7 As shown, a first wireless communication device (e.g., UE 120, network node 110, CU, DU, and / or RU) may transmit signals to a second wireless communication device (e.g., UE 120, network node 110, CU, DU, and / or RU). In some aspects, the first wireless communication device and the second wireless communication device may be part of a wireless network (e.g., wireless network 100) using a first RF technology (e.g., NB for assisting UWB) and / or a second RF technology (e.g., UWB).

[0115] like Figure 7 As shown in , the first wireless communication device may send a NB message (Msg) 705, and the second wireless communication device may attempt to receive the NB message (Msg) 705. The second wireless communication device may send a NB reply 710, and the first wireless communication device may attempt to receive the NB reply 710. The NB message 705 and the NB reply 710 may be communicated using frequency resources 715.

[0116] In some aspects, the first wireless communication device may determine to jump (e.g., away from the frequency resource 715) to a new frequency resource. For example, the first wireless communication device may determine to jump to the new frequency resource based at least in part on the failure of the NB message 705 and / or the NB reply 710. In some aspects, the first wireless communication device may determine to jump to the new frequency resource based at least in part on starting a new time domain resource (e.g., a time slot, a round, and / or a block).

[0117] like Figure 7 , the first wireless communication device may send a NB message 720, and the second wireless communication device may attempt to receive the NB message 720. The second wireless communication device may send a NB reply 725, and the first wireless communication device may attempt to receive the NB reply 725. The NB message 720 and the NB reply 725 may be transmitted using a frequency resource 730. The frequency resource 730 may have a frequency distance 735 from the frequency resource 715. In some aspects, the frequency distance may be selected based at least in part on satisfying a minimum frequency hopping distance as described herein.

[0118] In some aspects, the first wireless communication device may determine to jump (e.g., away from the frequency resource 730) to a new frequency resource. For example, the first wireless communication device may determine to jump to the new frequency resource based at least in part on the failure of the NB message 720 and / or the NB reply 725. In some aspects, the first wireless communication device may determine to jump to the new frequency resource based at least in part on starting a new time domain resource.

[0119] like Figure 7 As further shown in FIG. 7 , the first wireless communication device may send a NB message 740, and the second wireless communication device may attempt to receive the NB message 740. The second wireless communication device may send a NB reply 745, and the first wireless communication device may attempt to receive the NB reply 745. The NB message 740 and the NB reply 745 may be communicated using frequency resources 750. The frequency resource 755 may have a frequency distance 760 from the frequency resource 730. In some aspects, the frequency distance may be selected based at least in part on satisfying a minimum frequency hopping distance as described herein. In some aspects, the frequency resource 755 may be the same as the frequency resource 715.

[0120] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0121] Figure 8 is a diagram illustrating an example process 800 performed, for example, by a first wireless communication device in accordance with the present disclosure. The example process 800 is an example in which a first wireless communication device (eg, UE 120 or network node 110) performs operations associated with narrowband-assisted ultra-wideband frequency hopping.

[0122] like Figure 8 As shown in , in some aspects, process 800 may include: sending a first synchronization message to a second wireless communication device using a first RF technology and a first frequency resource, the first synchronization message being associated with synchronization of the second RF technology (block 810). For example, the first wireless communication device (e.g., using Fig. 9 The communication manager 140 or 150 and / or the transmission component 904 depicted in FIG. 1 may use the first RF technology and the first frequency resources to send a first synchronization message to the second wireless communication device, the first synchronization message being associated with synchronization of the second RF technology, as described above.

[0123] like Figure 8As further shown in , in some aspects, process 800 may include, after switching to a second frequency resource different from the first frequency resource, sending a second synchronization message to a second wireless communication device using the first RF technology, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource being based at least in part on one or more of transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or failure of the first synchronization message or failure of a reply to the first synchronization message from the second wireless communication device (block 820). For example, the first wireless communication device (e.g., using Fig. 9 The communication manager 140 or 150 and / or the transmission component 904 depicted in the figure can use the first RF technology to send a second synchronization message to the second wireless communication device after switching to a second frequency resource different from the first frequency resource, the second synchronization message is associated with synchronization of the second RF technology, and the switching to the second frequency resource is at least partially based on the transmission of the second synchronization message within the time slot, round or block associated with ranging or sensing, or one or more of the failure of the first synchronization message or the failure of the reply to the first synchronization message from the second wireless communication device, as described above.

[0124] Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0125] In a first aspect, switching to the second frequency resource occurs only if the first synchronization message or a reply to the first synchronization message fails.

[0126] In the second aspect, alone or in combination with the first aspect, transmission of a first synchronization message using a first frequency resource and transmission of a second synchronization message using a second frequency resource are based at least in part on one or more of a priority of the first frequency resource or a priority of the second frequency resource within a list of priority frequency resources for frequency hopping using a first RF technology for synchronization with a second RF technology.

[0127] In a third aspect, alone or in combination with one or more of the first and second aspects, the first frequency resource is a priority frequency resource and the second frequency resource is a non-priority frequency resource, or wherein the second frequency resource is a priority frequency resource, the first frequency resource is a non-priority frequency resource, and transmission of a first synchronization message on the first frequency resource is based at least in part on a failure of a previous synchronization message on an additional priority frequency resource.

[0128] In a fourth aspect alone or in combination with one or more of the first to third aspects, the priority of the first frequency resources or the priority of the second frequency resources is based at least in part on the possibility of interference from wireless signaling of the third RF technology.

[0129] In the fifth aspect, alone or in combination with one or more of the first to fourth aspects, the frequency distance between the first frequency resource and the second frequency resource is at least partially based on one or more of a minimum hopping distance, a pseudo-random additional hopping distance, or a modulo operation.

[0130] In the sixth aspect, alone or in combination with one or more of the first to fifth aspects, the minimum frequency hopping distance is based at least in part on one or more of a minimum frequency diversity distance associated with a width of a first frequency resource or a minimum interference distance associated with a channel resource width of a third RF technology.

[0131] In the seventh aspect, alone or in combination with one or more of the first to sixth aspects, process 800 includes selecting a second frequency resource based at least in part on generating a first random number as a temporary frequency hopping distance from a first frequency resource, wherein a temporary value of a second frequency resource is determined at least in part based on the first frequency resource and the temporary frequency hopping distance, or generating a second random number as one or more of an alternative to the first random number based at least in part on the temporary value of the second frequency resource being within the same frequency channel of the third RF technology.

[0132] In the eighth aspect alone or in combination with one or more of the first to seventh aspects, the third RF technology includes Wi-Fi technology.

[0133] In the ninth aspect alone or in combination with one or more of the first to eighth aspects, the first RF technology comprises narrowband technology, or wherein the second RF technology comprises ultra-wideband technology.

[0134] although Figure 8 Example blocks of process 800 are shown, but in some aspects, process 800 may include Figure 8 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in process 800. Additionally or alternatively, two or more of the blocks of process 800 may be executed in parallel.

[0135] Fig. 9is a diagram of an example apparatus 900 for wireless communication according to the present disclosure. Apparatus 900 may be a first wireless communication device, or a first wireless communication device may include apparatus 900. In some aspects, apparatus 900 includes a receiving component 902 and a transmitting component 904, which may communicate with each other (e.g., via one or more buses and / or one or more other components). As shown, apparatus 900 may communicate with other apparatuses 906 (such as UEs, base stations, or other wireless communication devices) using receiving component 902 and transmitting component 904. As further shown, apparatus 900 may include a communication manager 908 (e.g., communication manager 140 or 150).

[0136] In some aspects, the apparatus 900 may be configured to perform the Figure 6-Figure 7 Additionally or alternatively, the device 900 may be configured to perform one or more processes described herein, such as Figure 8 In some aspects, Fig. 9 The apparatus 900 and / or one or more components shown in FIG. 1 may include a combination of Figure 2 Additionally or alternatively, Fig. 9 One or more of the components shown in the figure may be combined with Figure 2 In some embodiments, the present invention may be implemented in one or more components described herein. Additionally or alternatively, one or more components in the set of components may be at least partially implemented as software stored in one or more memories. For example, a component (or portion of a component) may be implemented as instructions or codes stored in a non-transitory computer-readable medium and executable by a controller or processor to perform the function or operation of the component.

[0137] The receiving component 902 may receive communications from the device 906, such as reference signals, control information, data communications, or a combination thereof. The receiving component 902 may provide the received communications to one or more other components of the device 900. In some aspects, the receiving component 902 may perform signal processing (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding) on ​​the received communications and may provide the processed signals to one or more other components of the device 900. In some aspects, the receiving component 902 may include combining Figure 2 One or more antennas, modems, demodulators, MIMO detectors, receive processors, controllers / processors, one or more memories, or combinations thereof of a first wireless communication device are described.

[0138] Transmission component 904 may transmit communications, such as reference signals, control information, data communications, or a combination thereof, to device 906. In some aspects, one or more other components of device 900 may generate communications and may provide the generated communications to transmission component 904 for transmission to device 906. In some aspects, transmission component 904 may perform signal processing (e.g., filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, or encoding, etc.) on the generated communications and may send the processed signals to device 906. In some aspects, transmission component 904 may include a combination of Figure 2 One or more antennas, modems, modulators, transmit MIMO processors, transmit processors, controllers / processors, one or more memories, or combinations thereof of the described first wireless communication device. In some aspects, the transmission component 904 can be co-located with the reception component 902 in a transceiver.

[0139] The transmission component 904 can use the first RF technology and the first frequency resource to send a first synchronization message to the second wireless communication device, the first synchronization message being associated with synchronization of the second RF technology. The transmission component 904 can use the first RF technology to send a second synchronization message to the second wireless communication device after switching to a second frequency resource different from the first frequency resource, the second synchronization message being associated with synchronization of the second RF technology, and the switching to the second frequency resource is based at least in part on one or more of transmission of the second synchronization message within a time slot, round, or block associated with ranging or sensing, or failure of the first synchronization message or failure of a reply to the first synchronization message from the second wireless communication device.

[0140] The communication manager 908 can select the second frequency resource based at least in part on generating a first random number as a temporary frequency hopping distance from the first frequency resource, wherein the temporary value of the second frequency resource is determined at least in part based on the first frequency resource and the temporary frequency hopping distance, whether the temporary value of the second frequency resource is within the same frequency channel of the third RF technology, or generating a second random number as one or more of an alternative to the first random number based at least in part on the temporary value of the second frequency resource being within the same frequency channel of the third RF technology.

Additionally or alternatively, Fig. 9The group of (one or more) components shown in the figure may be described as being Fig. 9 The groups of other components shown in the figure perform one or more functions.
