[0002] This patent application claims priority to U.S. Patent Application No. 17 / 932,874, filed on September 16, 2022, entitled “TECHNIQUES FOR MOBILITY SUPPORT FOR USER EQUIPMENT WITH BACKSCATTERING RADIO” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of and incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for mobility support of user equipment (UE) with backscatter radio components. Background Art

[0004] 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 can support 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 promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region, or global level. New Radio (NR), which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, CP-OFDM 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 improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards.

[0029] The 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 presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be appreciated 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 or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functionality, or structures and functionality other than the various aspects of the disclosure set forth herein or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present claim.

[0030] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0031] 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 present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or 5G and beyond (e.g., 6G) RATs.

[0032] Figure 11 is a diagram illustrating an example of a wireless network 100. The wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network or elements of 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), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), or other entities. The network node 110 is an example of a network node that communicates with the UE 120. As shown, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, meaning that the converged network node is 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). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between 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)).

[0033] 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 a 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. For example, the network node 110 may include 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 transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, 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 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0034] 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 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 pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown, 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. The network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0035] In some aspects, the term "base station" or "network node" may refer to a converged 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-RT) RAN intelligent controller (RIC), or a 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 those described herein in conjunction with the network node 110. In some aspects, the term "base station" or "network node" may refer to a plurality of 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 geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these 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 base station function. In this way, a single device may include more than one base station.

[0036] 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 transmit 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 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications 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, or a relay, etc.

[0037] 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, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different effects on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0038] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the 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 also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0039] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, or a subscriber unit. 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 device, 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, or a satellite radio), an in-vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, or any other suitable device configured to communicate via a wireless or wired medium.

[0040] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices, or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing 284 that houses components of UE 120, such as a processor component or a memory component. 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., a memory) may be operably coupled, communicatively coupled, electronically coupled, or electrically coupled.

[0041] 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 also be referred to as a radio technology or air interface. Frequency may also be referred to as a carrier or frequency channel. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0042] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by network node 110.

[0043] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, or channels by frequency or wavelength. For example, 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. Although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, despite being distinct from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0044] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The bands falling within FR3 may inherit FR1 characteristics or FR2 characteristics, and thereby the features of FR1 or FR2 may be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0045] With these examples in mind, unless otherwise specifically stated, if the term "sub-6 GHz" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, frequencies that may be within FR1, or frequencies that may include mid-band frequencies. Additionally, unless otherwise specifically stated, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, frequencies that may be within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies that may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, or FR5) may be modified, and that the techniques described herein are applicable to those modified frequency ranges.

[0046] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may send capability information regarding beam tracking capabilities of a backscatter radio component of the UE for one or more nodes; perform beam tracking based on the beam tracking capabilities; and send beam information based at least in part on the beam tracking for one or more nodes. In some aspects, the communication manager 140 may obtain motion information based at least in part on one or more sensors of the UE; and output information indicating one or more beams for the backscatter radio component to the backscatter radio component of the UE based at least in part on the motion information. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0047] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may obtain capability information about a beam tracking capability of a backscatter radio component of a user equipment (UE) from the UE; and obtain beam information based at least in part on beam tracking from the UE. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0048] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0049] Figure 2 2 is a diagram illustrating an example 200 in which a network node 110 communicates with a UE 120 in a wireless network 100. 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 another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0050] At the network node 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may use one or more channel quality indicators (CQIs) received from the UE 120 to select one or more modulation and coding schemes (MCSs) for the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 using the MCS selected for the UE 120 and may provide data symbols to 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, 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., pre-coding) on ​​data symbols, control symbols, overhead symbols, or reference symbols, where 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, or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0051] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 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, 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 where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the 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, or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in a housing.

[0052] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 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.

[0053] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. An antenna panel, antenna group, set of antenna elements, or antenna array may include one or more antenna elements (in a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or coupled to one or more transmit or receive components (such as Figure 2 One or more antenna elements of one or more components).

[0054] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, 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 pre-decoded by the TX MIMO processor 266, where applicable, further processed by the 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, or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the processes described herein (eg, reference 280). Figures 4 to 11 ).

[0055] At the network node 110, uplink signals from the UE 120 or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232, shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted via the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the 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 or uplink communication. 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, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the processes described herein (e.g., reference 200 to FIG. 1 ). Figures 4 to 11 ).

[0056] In some aspects, the controller / processor 280 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be communicated to other systems or components, such as the UE 120. For example, the processing system of the UE 120 may be a system that includes various other components or subcomponents of the UE 120.

[0057] The processing system of UE 120 may interface with one or more other components of UE 120, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of UE 120 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that UE 120 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that UE 120 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0058] In some aspects, controller / processor 240 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be passed to other systems or components, such as network node 110. For example, a processing system of network node 110 may be a system that includes various other components or subcomponents of network node 110.

[0059] The processing system of the network node 110 may interface with one or more other components of the network node 110, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of the network node 110 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that the network node 110 may receive information or signal input, and may pass the information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that the network node 110 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0060] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, or Figure 2 Any other component of the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, or the like may perform one or more techniques associated with hybrid beam tracking, as described in more detail elsewhere herein. Figure 2 Any other component (or combination of components) may perform or direct e.g. Figure 7 The process of 700 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 memory 282 may include non-transitory computer-readable media storing one or more instructions (e.g., code or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 or UE 120 (e.g., directly, or after compilation, conversion, or interpretation), may cause the one or more processors, UE 120, or network node 110 to perform or direct, for example, Figure 7 The process of 700 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.

[0061] In some aspects, the UE 120 includes: a component for sending capability information about the beam tracking capability of the UE's backscatter radio component to one or more nodes; a component for performing beam tracking based on the beam tracking capability; and / or a component for sending beam information based at least in part on beam tracking to one or more nodes. In some aspects, the UE 120 includes: a component for obtaining motion information based at least in part on one or more sensors of the UE; and / or a component for outputting information indicating one or more beams for the backscatter radio component to the UE's backscatter radio component based at least in part on the motion information. In some aspects, the components for the UE 120 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, or Figure 4 One or more of the components shown.

[0062] Although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for 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.

[0063] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0064] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways using 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 equipment 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 functionality can be implemented as an aggregated base station (also referred to as 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).

[0065] 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 between 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 across 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), and the like.

[0066] Base station type operations or network designs may take into account the aggregated nature of base station functionality. 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 initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed independently. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual 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.

[0067] Figure 3 3 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0068] Each of these units (including CU 310, DU 330, RU 340) and near-RT RIC 325, non-RTRIC 315 and SMO framework 305) may include or be coupled to one or more interfaces, which are configured to receive or send signals, data or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of these units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, and the wireless interface may include a receiver, a transmitter or a transceiver (such as an RF transceiver), which is configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, or both.

[0069] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU310 may be implemented to communicate with the DU 330 for network control and signaling.

[0070] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0071] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc.) based on functional splitting (e.g., functional splitting defined by 3GPP) (such as lower layer functional splitting). In such an architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0072] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTRIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0073] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or communicate with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0074] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to regulate RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0075] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0076] Figure 4 4 is a diagram illustrating an example 400 of a UE (e.g., UE 120) including a main radio 405, a backscatter radio 410, a controller 415, and one or more sensors 420. The main radio 405 may be used for data and control communications of the UE. The main radio 405 may include one or more active radio frequency (RF) components, such as a power amplifier (PA) (for transmission) or a low noise amplifier (for reception). The main radio 405 may generate signals at a higher power (such as at, for example, 23 dBm) than the backscatter radio 410. The backscatter radio 410 may include a receiver associated with receiving wake-up signaling from a network, such as a low power wake-up receiver (LP-WUR). The backscatter radio 410 may use the backscatter function to send data and may receive data from the network. In some aspects, the backscatter radio 410 may use passive components for reception and transmission. In some aspects, the backscatter radio 410 may be used for low data rate communications (thereby providing lower latency than waking up the main radio 405 for low data rate communications).

[0077] In some aspects, the backscatter radio component 410 may include a radio frequency identifier (RFID) transponder, sometimes referred to as an RFID tag. For example, RFID tags may be used in many applications for inventory and asset management in warehouse operations, IoT, sustainable sensor networks in factories and / or agriculture, and smart home applications. RFID tags may transmit information-bearing signals upon receiving a signal, such as signals sent by backscatter modulation. RFID tags may operate without batteries with low operating expenses, low maintenance costs, and long life cycles. Passive RFID tags may harvest energy from air transmission and may use the harvested energy to power the transmitting and receiving circuits. In some aspects, RFID tags may be semi-passive or active, meaning that the RFID tag includes a battery that may power the operation of the RFID tag without performing energy harvesting.

[0078] In some aspects, the UE 120 or the backscatter radio component 410 can be considered a passive IoT device. The radio access technology (e.g., 5G / NR, 6G, etc.) can provide management of the passive IoT device. For example, a network node (e.g., a gNB) can read or write information stored on the passive IoT device. As another example, the network node can provide energy to the passive IoT device (e.g., for energy harvesting). As yet another example, the information-bearing signal can be reflected to the network node, and the network node can read the reflected signal to decode the information encoded on the signal by the passive IoT device.

[0079] As mentioned above, in some aspects, the backscatter radio may include an LP-WUR. The LP-WUR is a receiver that can monitor for wake-up signals when the main radio 405 is in a deep sleep state. The LP-WUR can be designed for low-power use, such as using low-power components and being powered separately from the main radio 405. When data communication is required, the backscatter radio 410 (e.g., the LP-WUR) can trigger the main radio 405 to wake up. For example, the backscatter radio 410 can monitor paging information related to the UE 120, and can wake up the main radio 405 when data transmission or reception is required (such as based at least in part on receiving a page directed to the UE 120). Waking up the main radio 405 can be associated with a fixed delay (e.g., a fixed transition time).

[0080] In some aspects, backscatter radio component 410 may include a transceiver. For example, the transceiver may perform envelope detection-based reception, such that a low noise amplifier (LNA) or a power amplifier (PA) is not required. As another example, the transceiver may perform load modulation-based transmission, such as by absorbing or reflecting incoming electromagnetic waves. In some aspects, backscatter radio component 410 may include an integrated circuit (or another form of processor) for processing uplink and downlink data (such as reading memory, calculating cyclic redundancy check (CRC), waking up main radio component 405, etc.). In some aspects, backscatter radio component 410 may incorporate an energy harvesting component so that backscatter radio component 410 can harvest energy in idle mode and charge the battery of backscatter radio component 410.

[0081] As used herein, "energy harvesting" may refer to obtaining energy from the environment of the backscatter radio 410. One example is RF energy harvesting, where an RF signal having certain frequency characteristics is converted into direct current (DC) power for the backscatter radio 410. Another example is solar energy harvesting, where photovoltaic energy is converted into DC power for the backscatter radio.

[0082] In some scenarios, the UE 120 may power down the main radio component 405, and may use the backscatter radio component 410 to communicate when the main radio component is powered down, thereby saving power. In some examples (such as in higher frequency bands, such as in FR2), the backscatter radio component 410 may need to maintain an appropriate beam for sending and receiving communications when the UE 120 is in motion or rotation (referred to herein as "mobility"). For example, a handheld device, smart phone, watch, or IoT device in power saving mode may move from one location to another and / or may undergo rotation, so that the beam used for communication by the backscatter radio component 410 (referred to as a service beam) needs to be updated from time to time. However, some techniques for maintaining a service beam (such as periodic measurements of reference signals sent by a network node) may involve a certain amount of power consumption and overhead at the backscatter radio component 410. In addition, if the position or orientation of the UE 120 changes significantly, the power consumption, overhead, and latency associated with scanning beam measurements to identify a new service beam may be significant.

[0083] Some techniques described herein provide an indication of one or more beams of a backscatter radio component 410 based at least in part on motion information obtained from one or more sensors 420. A controller 415 may obtain the motion information from the one or more sensors 420. The controller 415 may output information indicating one or more beams for the backscatter radio component 410 based at least in part on the motion information. Thus, maintaining an appropriate serving beam at the backscatter radio component 410 improves communication performance of the backscatter radio component 410 relative to maintaining the serving beam of the backscatter radio component 410 without reference to the one or more sensors 420 of the UE. In addition, power consumption, overhead, and latency that would otherwise be incurred by maintaining the serving beam using only beam measurements are reduced or avoided. In some examples (with respect to Figure 6 As described above, the techniques described herein provide signaling of information related to beam management of the backscatter radio component 410.

[0084] The controller 415 may use the motion information to identify one or more beams for the backscatter radio component 410. For example, the one or more beams may include a predicted beam (e.g., a transmit beam or a receive beam) that may be suitable for the backscatter radio component 410 given the updated position or orientation (determined based on the motion information) of the UE 120. As a simple example, if the motion information indicates that the UE 120 has rotated 90 degrees, the controller 415 may identify a predicted beam that is shifted 90 degrees from the previous serving beam of the backscatter radio component 410.

[0085] For example, the one or more sensors 420 may include an accelerometer, a gyroscope, an inertial sensor, a global positioning system (GPS) unit, or another sensor capable of providing information about the mobility of the UE 120. The controller 415 may include one or more processors, such as microprocessors.

[0086] The backscatter radio component 410 may have beam steering capabilities, such as the ability to update the service beam of the backscatter radio component 410 and / or the ability to form a beam for signal reflection. Different backscatter radio components 410 may have different beam steering capabilities. As a first example (referred to as "Case 1"), the backscatter radio component 410 may reflect signals in all directions (e.g., omnidirectionally, without performing beamforming). In Case 1, the backscatter radio component 410 may have a single antenna. As a second example (referred to as "Case 2"), the backscatter radio component 410 may reflect signals in one or more fixed directions (such as a reverse direction). For example, the backscatter radio component 410 may have an antenna array. As a third example (referred to as "Case 3"), the backscatter radio component 410 may support beamforming for both transmission (using a transmit beam) and reception (using a receive beam). About Figure 6 An example of signaling associated with Case 1, Case 2, and Case 3 is described.

[0087] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0088] Figure 5 is a diagram illustrating an example 500 of obtaining motion information according to the present disclosure. As shown, the controller 415 of the UE 120 may obtain sensor data 510 from one or more sensors 420 of the UE 120. In some aspects, the one or more sensors 420 may provide the sensor data 510 based at least in part on a configuration from the controller 415. For example, the controller 415 may configure the one or more sensors 420 to periodically provide the sensor data 510. The one or more sensors 420 may provide the sensor data 510 according to the periodicity, which is referred to herein as the controller 415 obtaining the sensor data 510. In some aspects, the controller 415 may obtain the sensor data 510 on demand, such as by reading the sensor data 510, sending a polling message to obtain the sensor data 510, or requesting the sensor data 510 from the one or more sensors 420. The sensor data 510 may include, for example, information indicating velocity (v), acceleration (a), rotation (k), and rotation (k). , lateral movement ( )、Rotational motion( ) etc. In some aspects, the sensor data 510 may relate to six degrees of freedom (DOF) of the UE 120, such as three lateral degrees of motion and three rotational degrees of motion.

[0089] The controller 415 may identify a serving beam for the UE 120 (e.g., a backscatter radio component 410 of the UE 120) based at least in part on the motion information. In some aspects, the sensor data 510 may be the motion information. In some aspects, the controller 415 may determine the motion information based at least in part on the sensor data 510. For example, the controller 415 may use the sensor data 510 to derive a velocity or acceleration of the UE 120, where the motion information includes the velocity or acceleration.

[0090] As shown by reference numeral 520, the controller 415 may output (e.g., to the backscatter radio component 410) information indicating a serving beam (e.g., a transmit beam and / or a receive beam) based at least in part on the motion information. For example, the serving beam may be a predicted serving beam based at least in part on the motion information of the UE 120 and the capabilities of the UE 120 (e.g., in combination with the UE 120's Figure 4 Case 1, Case 2 or Case 3).

[0091] For case 1, the controller 415 may provide (e.g., to the backscatter radio component 410) information indicating a preferred beam (e.g., a receive beam) for receiving energy from an energy transmitter (ET) such as a network node or another UE. Additionally or alternatively, the controller 415 may provide a mobility profile for the UE 120 so that the backscatter radio component 410 may report the mobility profile to the ET for transmit beam management at the ET. The mobility profile may indicate a mobility state (e.g., lateral speed, lateral direction, rotation speed, rotation direction, acceleration, or a combination thereof) of the UE 120. Additionally or alternatively, the controller 415 may provide information indicating a transmit beam sequence, such as a transmit beam sequence for transmission by the ET to the backscatter radio component 410 for a configured duration. In this example, the transmit beam sequence may be based at least in part on the motion information. For example, the beam sequence may include one or more beams directed to a predicted location of the UE 120 based on the motion information.

[0092] For case 2, the controller 415 may provide a mobility profile for the UE 120 to the backscatter radio component 410 so that the backscatter radio component 410 may report the mobility profile to the ET for transmit beam management at the ET. The mobility profile may indicate a mobility state (e.g., lateral speed, lateral direction, rotation speed, rotation direction, or a combination thereof) of the UE 120. Additionally or alternatively, the controller 415 may provide information indicating a transmit beam sequence, such as a transmit beam sequence for transmission by the ET to the backscatter radio component 410 during a configured duration. In this example, the transmit beam sequence may be based at least in part on the motion information. For example, the beam sequence may include one or more beams directed to a predicted position of the UE 120 according to the motion information. Additionally or alternatively, the controller 415 may provide information indicating a receive beam sequence, such as a receive beam sequence for reception at the backscatter radio component 410 during a configured duration. In this example, the receive beam sequence may be based at least in part on the capabilities of the UE 120. For example, the receive beam sequence may include only beams compatible with one or more fixed directions in which UE 120 is capable of generating beams in case 2.

[0093] For case 3, the controller 415 may provide the mobility profile for the UE 120 to the backscatter radio component 410, so that the backscatter radio component 410 may report the mobility profile to the ET for transmit beam management at the ET, or may perform receive beam management based at least in part on the mobility profile. The mobility profile may indicate a mobility state (e.g., lateral speed, lateral direction, rotation speed, rotation direction, or a combination thereof) of the UE 120. Additionally or alternatively, the controller 415 may provide information indicating a receive beam sequence, such as a receive beam sequence for reception at the backscatter radio component 410 for a configured duration.

[0094] As shown at reference numeral 530, in some aspects, the backscatter radio component 410 may measure a beam. For example, the backscatter radio component 410 may measure a predicted beam provided by the controller 415 at reference numeral 520. As another example, the backscatter radio component 410 may measure a beam determined by the backscatter radio component 410 (e.g., before receiving information indicating the predicted beam). In some aspects, the backscatter radio component 410 may perform layer 1 measurements on the beam, such as reference signal or other transmitted reference signal received power (RSRP) measurements on the beam, reference signal received quality (RSRQ) measurements, or signal to interference plus noise ratio (SINR) measurements. In some aspects, the backscatter radio component 410 may perform such measurements each time the beam is updated (e.g., each time the backscatter radio component 410 receives information indicating a serving beam for the backscatter radio component 410).

[0095] As shown by reference numeral 540, in some aspects, the backscatter radio component 410 may report information to the controller 415 based at least in part on the measured beam. For example, the information may include measurement information about the beam (e.g., RSRP value, RSRQ value, SINR value, etc.). In some aspects, the information may be referred to as feedback. In some aspects, the controller 415 may configure the acquisition of motion information based at least in part on the information shown by reference numeral 540. For example, if the measurement information fails to meet a threshold (e.g., if the beam is weak enough), the controller 415 may shorten the periodicity associated with obtaining the motion information. As another example, if the measurement information meets the threshold (e.g., if the beam is strong enough), the controller 415 may extend the periodicity associated with obtaining the motion information. As another example, if the measurement information fails to meet the threshold (e.g., if the beam is weak enough), the controller 415 may obtain the motion information on demand so that the controller 415 can identify an updated beam.

[0096] In some aspects, the reported information may relate to a single beam, such as a single beam for transmission and reception associated with a single node (e.g., a single static scenario). In some aspects, the reported information may indicate a first beam and a second beam. For example, for a backscatter radio component 410 that receives a signal from a first node using a receive beam and reflects the signal to a second node using a transmit beam (e.g., a dual static scenario), the reported information may indicate a first beam and a second beam. The reported information may indicate the beam using a beam index associated with the beam or using a set of beamforming weights that define the beam, etc.

[0097] In some aspects, the backscatter radio component 410 may perform beam training. "Beam training" refers to adjusting one or more parameters of a beam (or selecting an updated beam) based at least in part on beam measurements or feedback from another device. For example, the backscatter radio component 410 may measure two or more beams, or may perform one or more measurements on a serving beam. As another example, the backscatter radio component 410 may receive feedback (e.g., a measurement report) from a receiver of a signal sent using the beam. The backscatter radio component 410 may select a beam (e.g., an optimal beam) based on the beam measurements or feedback. For example, the backscatter radio component 410 may select a beam associated with a highest RSRP value, a highest RSRQ value, or a highest SINR value. As another example, the backscatter radio component 410 may select a beam based at least in part on an instruction from a network node to use a particular beam or switch to a particular beam. In some aspects, the backscatter radio component 410 may select a single updated beam for single static communication (e.g., when the one or more nodes include only a single node). In some aspects, the backscatter radio component 410 can select an updated transmit beam and an updated receive beam for bi-static communication (eg, when the one or more nodes include a first node and a second node). In some aspects, the backscatter radio component 410 can report the updated beam to the controller 415.

[0098] As used herein, "beam tracking" refers to selecting a serving beam (e.g., an optimal beam to send or receive communications) for a backscatter radio component of a UE based at least in part on sensor data at the UE, wherein the sensor data is obtained from one or more sensors 420. In some aspects, beam tracking may include obtaining sensor data. In some aspects, beam tracking may include performing beam measurements on the serving beam and / or one or more other beams and / or updating the beam (e.g., beam refinement) based at least in part on the beam measurements. "Beam tracking" may be referred to as autonomous beam tracking.

[0099] As shown by reference numeral 550, in some aspects, the controller 415 (or the backscatter radio component 410, directly or via the controller 415) can trigger the main radio component 405 to wake up from a sleep state (e.g., a power-off state, a deep sleep state). For example, the controller 415 or the backscatter radio component 410 can trigger the main radio component 405 to enter an active state (e.g., a power-on state). In some aspects, the controller 415 or the backscatter radio component 410 can trigger the main radio component 405 to wake up based at least in part on the sensor data 510. For example, if the sensor data 510 indicates that the motion state of the UE 120 exceeds the capabilities of the backscatter radio component 410 (e.g., indicating the capabilities of the maximum motion state at which the backscatter radio component 410 can perform beam management), the controller 415 can trigger the main radio component 405 to wake up from the sleep state. In some aspects, the controller 415 or the backscatter radio component 410 can trigger the main radio component 405 to wake up based at least in part on beam training at the backscatter radio component 410. For example, if a beam measurement fails to meet a threshold, if the serving beam of the backscatter radio 410 experiences a beam failure, etc., the controller 415 may trigger the main radio 405 to wake up.

[0100] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0101] Figure 6 is a diagram illustrating an example 600 of signaling for mobility of a backscatter radio component according to the present disclosure.

[0102] Example 600 includes a UE (eg, UE 120) and one or more nodes (eg, network node 110 or UE 120). UE 120 may include Figure 4 In some aspects, the one or more network nodes may include a first node (e.g., a transmitting node) and a second node (e.g., a receiving network node). Figure 6 The operations described in as being performed by UE 120 may be performed by one or more components of UE 120.

[0103] Example 600 relates to beam tracking (eg, autonomous beam tracking) of a UE, such as with respect to Figure 5The UE may perform beam tracking based on motion information at the UE (such as motion information determined using sensor data of the UE). A beam at the UE (such as a transmit beam or a receive beam) may belong to a beam pair, wherein the second beam in the beam pair is at a node in one or more nodes. For example, the beam pair may include a receive beam at the UE and a transmit beam at the node, or may include a transmit beam at the UE and a receive beam at the node. If the UE autonomously selects a serving beam (such as based at least in part on motion information determined at the UE), the node may not be able to access information about which beam is selected by the UE. In such cases, the node may continue to use an inappropriate beam (which has become inappropriate through the movement of the UE), or may select an inappropriate beam for a beam pair between the node and the UE, which reduces throughput and coverage. Some of the techniques described herein provide signaling between a backscatter radio component of the UE and one or more nodes to support beam tracking at the UE. For example, the UE may report beam information related to beam tracking, such as indicating a selected beam, a preferred beam, a measurement value at the UE, and the like. A node (e.g., one or more nodes) may use the beam information to communicate with the UE. For example, the node may communicate using a beam indicated by the beam information, and may select a beam that provides a threshold performance as a beam peer to the beam selected at the UE. Thus, throughput and coverage are improved.

[0104] As indicated by reference numeral 610, the UE may send capability information to one or more nodes. The capability information may relate to (e.g., include) beam tracking capabilities of a backscatter radio component of the UE. For example, the beam tracking capability may indicate whether the backscatter radio component supports beam tracking using the backscatter radio component when the main radio component of the UE is disabled. As another example, the beam tracking capability may indicate whether the UE (e.g., the controller 415 of the UE) is able to autonomously track a beam using the UE's sensors (e.g., one or more sensors 420) when the main radio component of the UE is disabled. As yet another example, the beam tracking capability may indicate whether the UE supports beam management (e.g., beam measurement, signaling of a preferred beam, signaling of a beam selected by the controller 415, beam failure detection, and / or beam failure recovery) with one or more nodes using the backscatter radio component.

[0105] In some aspects, the capability information may be sent while the primary radio of the UE is active. For example, the UE may send the capability information (using the primary radio or the backscatter radio) before deactivating the primary radio. In some aspects, the UE may send the capability information via a side link, such as a direct communication with another UE, or a broadcast or multicast communication to a group of UEs. In some aspects, the UE may send the capability information via a radio access link, such as a Uu link with a network node.

[0106] In some aspects, the capability information may indicate a threshold associated with the motion state of the UE. For example, the capability information may indicate a rate threshold, a speed threshold, an acceleration threshold, etc. The threshold may be associated with triggering a beam training procedure. For example, if the motion state of the UE (e.g., rate, speed, acceleration) satisfies the threshold, the UE or node may trigger the beam training procedure. If the motion state of the UE does not satisfy the threshold, the UE may perform autonomous beam tracking, such as with respect to FIG. Figure 5 For example, when the motion state of the UE does not satisfy the threshold, the UE may use the motion information to select a beam for the backscatter radio component, and if the motion state satisfies the threshold, a beam training procedure may be triggered (or a trigger for the beam training procedure may be received). In some aspects, one or more nodes may trigger a beam training procedure based at least in part on the threshold. For example, a node may determine that the motion state of the UE satisfies the threshold, and may output (e.g., send to the UE, provide for transmission to the UE) a trigger for the beam training procedure based at least in part on the motion state of the UE satisfying the threshold.

[0107] In some aspects, the capability information may indicate the beam steering capability of the backscatter radio component. For example, the capability information may indicate whether the UE supports the combination of Figure 4 Case 1, Case 2, or Case 3 described above. Therefore, the capability information may indicate whether the backscatter radio component supports reflection in all directions (e.g., without beamforming), one or more fixed directions, or in configurable directions. The network node may perform single static or dual static backscatter communication with the backscatter radio component (by sending a signal to the backscatter radio component for backscattering to one or more receivers) based at least in part on the capability information indicating that the UE supports Case 1, Case 2, or Case 3. For example, if the backscatter radio component backscatters signals in all directions, the network node may notify one or more receivers (e.g., nodes or UEs) close to the backscatter radio component to receive and decode the backscatter signals. If the backscatter radio component backscatters only in a specific direction, the network node may coordinate the receiver in the specific direction to receive the backscatter signal. If the backscatter radio component supports beamforming, the network node may send an indication to the selected receiver for the UE (e.g., backscatter radio) to beamform the backscatter signal.

[0108] As shown in reference numeral 620, one or more nodes may output configuration information, and the UE may receive the configuration information. In some aspects, the configuration information may indicate a threshold for beam tracking. For example, the node may configure a measurement threshold (e.g., an RSRP threshold, an RSSI threshold, etc.) to declare a beam failure at the backscatter radio component. The backscatter radio component may perform beam measurements on the serving beam of the backscatter radio component. If the serving beam fails to meet the measurement threshold (e.g., if the measurement associated with the serving beam is below the configured measurement threshold), the UE may declare a beam tracking failure. For example, the UE may send an indication that the serving beam failed to meet the measurement threshold. In some aspects, when the serving beam fails to meet the measurement threshold, the UE may wake up the main radio component of the UE. For example, the UE may wake up the main radio component by powering on one or more active components of the main radio component (e.g., a digital / analog converter, an analog / digital converter, a PA, an LNA) and / or by starting to use the main radio component for data or control communications. In some aspects, the UE may wake up the primary radio component based at least in part on the sensor data (e.g., sensor data 510) being insufficient to support the mobility of the backscatter radio component. For example, if the motion state of the UE exceeds a configured threshold, the UE (or one or more nodes) may wake up the primary radio component, as described elsewhere herein. In some aspects, when the serving beam fails to meet the measurement threshold, the UE may initiate a beam failure recovery procedure. For example, the UE may perform a random access channel (RACH) procedure on a candidate beam selected by the UE.

[0109] In some aspects, the configuration information may indicate a timer associated with the measurement threshold. For example, the UE may start a timer upon determining that the serving beam fails to meet the measurement threshold (e.g., indicating that beam pairing between the UE and one or more nodes is unsuccessful). When the backscatter radio component of the UE cannot find a beam that meets the measurement threshold, and when the UE does not receive feedback from the one or more nodes, the UE may run a timer (e.g., the timer may not be paused, canceled, or reset). The feedback may include, for example, an acknowledgement or negative acknowledgement (ACK / NACK) from one or more nodes or an indication of expected packet reception from one or more nodes. If the timer expires and the backscatter radio component of the UE does not find a beam that meets the measurement threshold and no feedback is received, the UE may trigger activation of the primary radio component of the UE.

[0110] As shown in reference numeral 630, the UE may perform autonomous beam tracking. For example, the UE may use motion information based at least in part on the UE's sensor data to select a serving beam for the UE's backscatter radio component, such as with respect to FIG. Figure 5As another example, the backscatter radio may perform beam measurements on the backscatter radio's serving beam and / or one or more other beams so that the backscatter radio may select a preferred beam (eg, for communicating with an ET, etc.).

[0111] As shown in reference numeral 640, a UE (e.g., a backscatter radio component) may send beam information based at least in part on beam tracking to one or more nodes. For example, the beam information may indicate a preferred beam for communicating with the ET. In some aspects, the preferred beam may be a transmit beam at the ET. For example, the UE may identify a preferred beam based at least in part on beam measurements (e.g., RSRP measurements, RSSI measurements, etc.) during autonomous beam tracking, and may send beam information identifying the preferred beam so that the ET may use the preferred beam to transmit to the UE. In some aspects, the beam information may be independent of the beam steering capability of the UE. For example, the UE may send beam information identifying the preferred beam regardless of the beam steering capability of the backscatter radio component. In some aspects, the beam information may include a mobility profile, information indicating a transmit beam sequence, information indicating a receive beam sequence, or a combination thereof, as described elsewhere herein.

[0112] As shown in reference numeral 650, in some examples, the UE may receive a signal from one or more nodes indicating deactivation of beam tracking. For example, a node (e.g., one or more nodes) may output a signal indicating deactivation of beam tracking. As shown in reference numeral 660, the UE may deactivate beam tracking of reference numeral 630 according to the signal. In some aspects, a node (e.g., one or more nodes) may activate beam tracking. For example, the node may send a signal indicating activation of beam tracking (e.g., in combination with capability information indicating that the UE supports beam tracking capability, in combination with an indication that the UE provides feedback or motion state that facilitates beam tracking, in combination with network-side measurements indicating that the UE can support autonomous beam tracking), and the UE may activate beam tracking of reference numeral 630 according to the signal. Thus, the node may turn autonomous beam tracking on or off, which enables the node to deactivate beam tracking in a case where the node is to use a different procedure (e.g., a predefined procedure) to perform beam tracking of the UE.

[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 illustrating an example process 700, performed, for example, by a UE, in accordance with the present disclosure. Example process 700 is an example of operations in which a UE (eg, UE 120) performs operations associated with mobility support for UEs having backscatter radio components.

[0115] like Figure 7 As shown, in some aspects, process 700 may include sending capability information regarding beam tracking capabilities of a backscatter radio component of the UE to one or more nodes (block 710). For example, a UE (e.g., using Fig. 9 The communications manager 140 and / or transmitting component 904 depicted in FIG. 1 may transmit capability information regarding beam tracking capabilities of a backscatter radio component of a UE for one or more nodes, as described above.

[0116] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include performing beam tracking according to a beam tracking capability (block 720). For example, a UE (e.g., using Fig. 9 The communication manager 140 and / or beam tracking component 908 depicted in FIG. 1 may perform beam tracking according to beam tracking capabilities, as described above.

[0117] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include sending beam information based at least in part on beam tracking to one or more nodes (block 730). For example, a UE (e.g., using Fig. 9 The communication manager 140 and / or the transmitting component 904 depicted in FIG. 1 can transmit beam information based at least in part on beam tracking for one or more nodes, as described above.

[0118] Process 700 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.

[0119] In a first aspect, the beam tracking capability of the backscatter radio component is used to perform beam tracking using the backscatter radio component when a primary radio component of the UE is deactivated.

[0120] In a second aspect, alone or in combination with the first aspect, the beam tracking capability indicates whether the UE supports beam management with the one or more nodes using the backscatter radio component.

[0121] In a third aspect, alone or in combination with one or more of the first and second aspects, the beam tracking capability indicates whether the UE is able to autonomously track a beam using a sensor of the UE when a primary radio component of the UE is deactivated.

[0130] In a twelfth aspect, alone or in combination with one or more of the first to eleventh aspects, the beam information indicates a preferred beam for communicating with the energy transmitter. Thus, for the communication with the energy transmitter, energy collection and communication efficiency are improved. The communication may include data communication, control communication, or excitation transmitted by the energy transmitter.

[0131] In a thirteenth aspect, alone or in combination with one or more of the first to twelfth aspects, process 700 includes: receiving configuration information indicating a measurement threshold associated with the beam tracking, wherein performing beam tracking further includes identifying a beam having a measurement satisfying the measurement threshold. Thus, a node (e.g., a network node) may configure the measurement threshold for a beam to ensure satisfactory performance of a beam pair including the beam selected by the UE.

[0132] In a fourteenth aspect, either alone or in combination with one or more of the first to thirteenth aspects, process 700 comprises declaring a beam tracking failure or initiating a beam failure recovery procedure based at least in part on the measurement failing to satisfy the measurement threshold.

[0133] In a fifteenth aspect, alone or in combination with one or more of the first to fourteenth aspects, process 700 includes triggering activation of a primary radio component of the UE based at least in part on the measurement failing to satisfy the measurement threshold.

[0134] In a sixteenth aspect, either alone or in combination with one or more of aspects one to fifteen, the configuration information indicates a timer associated with the measurement failing to satisfy the measurement threshold, wherein triggering activation of the primary radio component further comprises triggering activation of the primary radio component based at least in part on expiration of the timer.

Additionally or alternatively, two or more of the blocks of process 700 may be performed in parallel.

Example process 800 is an example in which an apparatus (eg, one or more processors of a UE, controller 415) performs operations associated with mobility support for a UE having a backscatter radio component.

[0137] like Figure 8 As further shown, in some aspects, process 800 may include obtaining motion information based at least in part on one or more sensors of the UE (block 810). For example, the apparatus (e.g., using Fig. 9 The communication manager 140 and / or the motion sensing component 910 depicted in FIG. 1 may obtain the motion information based at least in part on one or more sensors of the UE, as described above.

[0138] like Figure 8As further shown in FIG. 8 , in some aspects, process 800 may include: outputting information indicating one or more beams for a backscatter radio component of the UE based at least in part on the motion information (block 820). For example, the apparatus (e.g., using Fig. 9 The communication manager 140 and / or the indicating component 912 depicted in FIG. 1 may output information indicating one or more beams for a backscatter radio component of the UE based at least in part on the motion information, as described above.

[0139] 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.

[0142] In a third aspect, alone or in combination with one or more of the first and second aspects, the information indicative of the one or more beams is based at least in part on a beam steering capability of the backscatter radio component.

[0143] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the one or more beams include at least one of a transmit beam or a receive beam.

[0144] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 800 includes receiving measurement information about the one or more beams from the backscatter radio component.

[0145] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, process 800 includes receiving information indicating an updated beam from the backscatter radio component based at least in part on a beam training procedure.

[0146] In the seventh aspect, alone or in combination with one or more of the first to sixth aspects, the information indicating the updated beam indicates a single updated beam for monostatic communication or at least one of an updated transmit beam and an updated receive beam for bistatic communication.

Additionally or alternatively, two or more of the blocks of process 800 may be performed in parallel.

[0151] Fig. 9 is a diagram of an example apparatus 900 for wireless communication according to the present disclosure. Apparatus 900 may be a UE, or a UE 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 another apparatus 906 (such as a UE, a base station, or another wireless communication device) using receiving component 902 and transmitting component 904. As further shown, apparatus 900 may include a communication manager 140.
