[0001] Cross - Reference to Related Applications

[0002] This patent application claims priority to U.S. Non - Provisional Patent Application No. 18 / 050,256, entitled "BEAM SWEEPING BASED ON A USER EQUIPMENT OPERATING STATE", filed on October 27, 2022, which is hereby incorporated by reference in its entirety. Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communication and relate to techniques and apparatus for beam sweeping based on a user equipment operating state.

[0004] Background

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ multiple access techniques capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access techniques 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 / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0006] 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. A UE may communicate with a 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., sidelink (SL), Wireless Local Area Network (WLAN) link, and / or Wireless Personal Area Network (WPAN) link, etc.).

[0007] The above multi-access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at the urban, national, regional, and / or global levels. New Radio (NR) (which may be referred to as 5G) is an enhanced set of the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectral efficiency, reduce costs, enhance services, utilize new spectrums, and better integrate with other open standards by 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, thereby better supporting mobile broadband Internet access. With the continuous increase in the demand for mobile broadband access, further improvements to LTE, NR, and other radio access technologies are still useful. SUMMARY OF THE INVENTION

[0023] Aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Those skilled in the art will understand that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. In addition, the scope of the present disclosure is intended to cover such apparatus or methods practiced using other structures, functions, or combinations of structures and functions in addition to or different from the aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0024] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the 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 these elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0025] Although terms that are generally associated with 5G or New Radio (NR) radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0026] Figure 1FIG. is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 can be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or can include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, and so on. The wireless network 100 can include one or more network nodes 110 (shown as network nodes 110a, network nodes 110b, network nodes 110c, and network nodes 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UEs 120a, UEs 120b, UEs 120c, UEs 120d, and UEs 120e), and / or other entities. The network nodes 110 are network nodes that communicate with the UEs 120. As shown, the network nodes 110 can include one or more network nodes. For example, the network nodes 110 can be integrated network nodes, which means that the integrated network nodes are 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 nodes 110 can be disaggregated network nodes (sometimes referred to as disaggregated base stations), which means that the network nodes 110 are 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).

[0027] In some examples, the network nodes 110 are or include network nodes that communicate with the UEs 120 via radio access links, such as RUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via fronthaul links or midhaul links, such as DUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via midhaul links or communicate with the core network via a backhaul link, such as CUs. In some examples, the network nodes 110 (such as integrated network nodes 110 or disaggregated network nodes 110) can include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network nodes 110 can include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, transmit receive points (TRPs), DUs, RUs, CUs, mobility elements of the network, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, the network nodes 110 can be interconnected with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0028] In some examples, network node 110 may provide communication coverage for a specific geographical area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macro cells, picocells, femtocells, and / or another type of cell. A macro cell may cover a relatively large geographical area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with a service subscription. A picocell may cover a relatively small geographical area and may allow unrestricted access by UEs 120 with a service subscription. A femtocell may cover a relatively small geographical area (e.g., a home) and may allow restricted access by UEs 120 associated with the femtocell (e.g., UEs 120 in a Closed Subscriber Group (CSG)). The network node 110 for a macro cell may be referred to as a macro network node. The network node 110 for a picocell may be referred to as a pico network node. The network node 110 for a femtocell may be referred to as a femto network node or a home network node. In Figure 1 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 picocell 102b, and network node 110c may be a femto network node for femtocell 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 geographical area of a cell may move according to the location of a moving 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 disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, the "base station" or "network node" may refer to a CU, a DU, an 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 single device configured to perform one or more functions, such as those described herein in connection with 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 multiple different devices (which may be located at the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform 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 base station function among base station functions, rather than another base station function. In this way, a single device may include more than one base station.

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

[0031] 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 transmission power levels, different coverage areas, and / or different impacts on interference in wireless network 100. For example, a macro network node may have a high transmission power level (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmission power levels (e.g., 0.1 watt to 2 watts).

[0032] The network controller 130 may be coupled to or communicate with a set 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 fronthaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless fronthaul communication link or a wired fronthaul 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] UEs 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. The UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. The 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, a superbook, 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, industrial manufacturing equipment, a global positioning system device, UE functionality 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 machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. The MTC UE and / or the eMTC UE may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as narrowband IoT (NB-IoT) devices. Some UEs 120 may be considered customer premises equipment. The UE 120 may be included inside a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

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

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

[0037] Devices of wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. according to frequency or wavelength. For example, devices of wireless network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). It should be understood that although a part of FR1 is greater than 6 GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Regarding FR2, a similar naming issue sometimes occurs, which is usually (interchangeably) referred to as the “millimeter wave” band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz – 300 GHz) identified by the International Telecommunication Union (ITU) as the “millimeter wave” band.

[0038] The frequency between FR1 and FR2 is generally referred to as the mid-band frequency. Recent 5G NR studies have identified the operating bands for these mid-band frequencies as frequency range designations FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to the mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operations 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] Given the above examples, unless otherwise specifically stated, it should be understood that if terms such as "below 6 GHz" are used herein, such terms can broadly represent frequencies that can be below 6 GHz, can be within FR1, or can include mid-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that if terms such as "millimeter wave" are used herein, such terms can broadly represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or can be within the EHF band. Given that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein apply to those modified frequency ranges.

[0040] In some aspects, a UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may: perform a beam scanning procedure that selects a communication beam for communication in a wireless network, the beam scanning procedure being at least partially based on a beam scanning subset of beams that is dynamically selected from a plurality of beams at least partially based on the current UE operating state; and communicate in the wireless network at least partially based on the communication beam that is selected at least partially based on the beam scanning procedure. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0041] As indicated above, Figure 1 is provided as an example. Other examples may be different from the examples described with respect to Figure 1 what is described.

[0042] Figure 2FIG. 200 illustrates an example 200 of communication between a network node 110 and 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 through 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 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 radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0043] At network node 110, transmit processor 220 may receive data destined for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCSs) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols to UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the 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 through 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 may process the corresponding output symbol stream (e.g., for OFDM) using the corresponding modulator component to obtain an output sample stream. Each modem 232 may also process the output sample stream (e.g., convert to analog, amplify, filter, and / or upconvert) using the corresponding modulator component to obtain a downlink signal. Modems 232a through 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 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 condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal using the corresponding demodulator component to obtain input samples. Each modem 254 may further process the input samples (e.g., for OFDM) using the demodulator component to obtain received symbols. The MIMO detector 256 may obtain the received symbols from the modems 254, may perform MIMO detection on the received symbols when applicable, and may provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide the decoded data for the UE 120 to the data sink 260, and may provide the 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 reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0045] 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.

[0046] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include 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., or may be included within 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. Antenna panels, antenna groups, a set of antenna elements, and / or antenna arrays 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, and / or one or more antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 one or more components) of

[0047] 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 reporting 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 pre-coded by the TX MIMO processor 266 if 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 the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and / or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller / processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figures 5 to 7 )).

[0048] At the network node 110, the uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., the demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and 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 communication and / 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 the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and / or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller / processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to Figures 5 to 7 ).

[0049] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component of may perform one or more techniques associated with beam scanning based on the user equipment operating state, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component of may execute or direct the operation of, for example, Figure 6 process 600 and / or other processes as described herein. The memories 242 and 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication (e.g., code and / or program code). For example, when the one or more instructions are executed by one or more processors of network node 110 and / or UE 120 (e.g., executed directly, or after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or network node 110 may execute or direct the operation of, for example, Figure 6 process 600 and / or other processes as described herein. In some examples, executing the instructions may include running the instructions, transforming the instructions, compiling the instructions, and / or interpreting the instructions, and so on.

[0050] In some aspects, a UE (e.g., UE 120) includes: components for performing a beam scanning procedure that selects a communication beam for communication in a wireless network, the beam scanning procedure being at least partially based on a beam scanning subset of beams, the beam scanning subset being dynamically selected from a plurality of beams at least partially based on the current UE operating state; and / or components for communicating in the wireless network at least partially based on the communication beam, the communication beam being selected at least partially based on the beam scanning procedure. The components for a UE to perform the operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0051] Although Figure 2 the boxes in are illustrated as different components, the functions described above for these boxes may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described for transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be executed by or under the control of controller / processor 280.

[0052] As indicated above, Figure 2 is provided as an example. Other examples may differ from the example Figure 2 described above.

[0053] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, network nodes, network entities, mobility elements of the network, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in a converged or decomposed architecture. For example, a base station (such as Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as a converged base station (also referred to as a stand-alone base station or a monolithic base station) or a decomposed base station. A "network entity" or "network node" can 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).

[0054] A converged base station (e.g., a converged network node) can be configured to utilize a radio protocol stack 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) can be configured to utilize a protocol stack 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, a CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually spread across one or more other network nodes. A DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can 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.

[0055] Base station type operations or network designs can consider the aggregation characteristics of base station functionality. For example, a decomposed base station can 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 separately. A decomposed base station can include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which can achieve flexibility in network design. The individual units of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0056] Figure 3 are diagrams illustrating examples 300, 310, and 320 of a beam management procedure according to the present disclosure. As Figure 3 shown, examples 300, 310, and 320 include a UE 120 communicating with a network node 110 in a wireless network (e.g., wireless network 100). However, Figure 3 the devices shown are provided as examples, and the wireless network may support communication and beam management between other devices (e.g., between UE 120 and a network node 110 or a TRP, between a mobile terminal node and a control node, between an IAB sub-node and an IAB parent node, and / or between a scheduled node and a scheduling node). In some aspects, UE 120 and network node 110 may be in a connected state (e.g., a Radio Resource Control (RRC) connected state).

[0057] As Figure 3 shown, example 300 may include a network node 110 (e.g., one or more network node devices such as an RU, a DU, and / or a CU, etc.) and a UE 120 communicating to perform beam management using one or more reference signals such as a Channel State Information Reference Signal (CSI-RS) and / or a Synchronization Signal Block (SSB). Example 300 depicts a first beam management procedure, which may be referred to as a beam selection procedure, an initial beam capture procedure, a beam scanning procedure, a cell search procedure, and / or a beam search procedure. As Figure 3 shown in and example 300, network node 110 may send one or more reference signals to UE 120. Network node 110 may indicate the configuration of the reference signals to UE 120, such as by indicating a periodic reference signal configuration (e.g., using RRC signaling), a semi-persistent reference signal configuration (e.g., using a Medium Access Control (MAC) Control Element (CE) signaling), and / or an aperiodic reference signal configuration (e.g., using Downlink Control Information (DCI)). Other examples of beam management procedures may include uplink beam management procedures using a Sounding Reference Signal (SRS) sent by UE 120, such as a U1 beam management procedure (e.g., an initial selection of an uplink beam by a network entity or UE), a U2 beam management procedure (e.g., a refinement of an uplink beam by a network entity), and / or a U3 beam management procedure (e.g., a refinement of an uplink beam by UE).

[0058] The first beam management procedure may include the network node 110 performing beam scanning on multiple transmit (Tx) beams. "Beam scanning" may refer to transmitting and / or receiving one or more wireless signals (e.g., reference signals) at least partly based on transmit beams having different spatial directions and / or spatial widths. By way of illustration, the network node 110 may transmit a reference signal using a first transmit beam associated with a first spatial direction and / or spatial width during a first time period, and then transmit the same reference signal and / or a different reference signal using a second transmit beam associated with a second spatial direction and / or a second spatial width during a second time period. In some aspects, the network node 110 may successively transmit beams having different spatial directions and / or spatial widths during different time periods (e.g., scanning by transmitting each beam included in a list of beams one at a time). Thus, the network node 110 may use one or more transmit beams for beam management to transmit reference signals.

[0059] To enable the UE 120 to perform receive (Rx) beam scanning, the network node may transmit each RS multiple times (e.g., with repetition) within the same reference signal (RS) resource set using transmit beams, such that the UE 120 may sweep through receive beams in multiple transmit instances. For example, if the network node 110 has a set of N transmit beams and the UE 120 has a set of M receive beams (e.g., where N and M are integers), the reference signal may be transmitted M times on each of the N transmit beams, such that the UE 120 may receive M instances of the reference signal per transmit beam. In other words, for each transmit beam of the network node 110, the UE 120 may perform beam scanning of the UE 120's receive beams. In some aspects, the UE 120 may perform beam scanning at least partly based on a beam codebook that indicates a list of beams to be used as part of the beam scanning (e.g., a list of receive beams and / or a list of transmit beams). Thus, the first beam management procedure may enable the UE 120 to use different receive beams to measure reference signals on different transmit beams to support the selection of a network node 110 transmit beam / UE 120 receive beam beam pair. The UE 120 may report measurements to the network node 110 such that the network node 110 can select one or more beam pairs for communication between the network node 110 and the UE 120.

[0060] As Figure 3 shown, example 310 may include the network node 110 and the UE 120 communicating to perform beam management using one or more reference signals. Example 310 depicts a second beam management procedure, which may be referred to as a beam refinement procedure, a network node beam refinement procedure, a TRP beam refinement procedure, and / or a transmit beam refinement procedure. As Figure 3As shown in Example 310, the reference signal used as part of the second beam management procedure may be configured as one or more downlink reference signals transmitted from network node 110 to UE 120. The reference signal may be configured as an aperiodic reference signal (e.g., using DCI).

[0061] The second beam management procedure may include network node 110 performing beam scanning on one or more transmit beams. The one or more transmit beams may be a subset of all transmit beams associated with network node 110 (e.g., determined at least in part based on measurements reported by UE 120 in connection with the first beam management procedure). Network node 110 may use each of the one or more transmit beams used for beam management to transmit a reference signal. UE 120 may measure each reference signal using a single (e.g., the same) receive beam (e.g., determined at least in part based on measurements performed in connection with the first beam management procedure). The second beam management procedure may enable network node 110 to select an optimal transmit beam at least in part based on one or more measurements of the reference signal reported by UE 120 (e.g., measured by UE 120 using a single receive beam).

[0062] As Figure 3 shown, Example 320 depicts a third beam management procedure, which may be referred to as a beam refinement procedure, a UE beam refinement procedure, and / or a receive beam refinement procedure. As Figure 3As shown in Example 320, one or more reference signals may be configured as downlink reference signals transmitted from network node 110 to UE 120. The reference signal may be configured as aperiodic (e.g., using DCI). The third beam management procedure may include network node 110 transmitting the one or more reference signals using a single transmit beam (e.g., determined at least in part based on measurements reported by UE 120 in conjunction with the first beam management procedure and / or the second beam management procedure). To enable UE 120 to perform receive beam scanning, the network node may transmit the reference signal multiple times (e.g., using repetition) within the same RS resource set using the transmit beam, such that UE 120 may sweep through one or more receive beams in multiple transmit instances. In some aspects, UE 120 may select a receive beam at least in part based on a beam codebook that specifies a list of beams. Alternatively or additionally, the UE may select a subset of all receive beams associated with UE 120 (e.g., determined at least in part based on measurements performed in conjunction with the first beam management procedure and / or the second beam management procedure). The third beam management procedure may enable network node 110 and / or UE 120 to select an optimal receive beam at least in part based on the reported measurements received from UE 120 (e.g., the reported measurements of the reference signals of the transmit beam received from the UE using the one or more receive beams). Thus, the beam management procedures (e.g., the first beam management procedure, the second beam management procedure, and / or the third beam management procedure) may enable network node 110 and / or UE 120 to select transmit and / or receive beams having higher signal quality relative to other beams. The beams associated with higher signal quality may enable network node 110 and UE 120 to meet the link budget.

[0063] As indicated above, Figure 3 is provided as an example of a beam management procedure. Other examples of beam management procedures may differ from the examples described with respect to Figure 3 For example, UE 120 and network node 110 may perform the third beam management procedure before performing the second beam management procedure, and / or UE 120 and network node 110 may perform a similar beam management procedure to select a UE transmit beam.

[0064] Figure 4 is a diagram illustrating Example 400 of a beam codebook according to the present disclosure.

[0065] A codebook can provide information about a data set that enables a device to decode the data set. For example, the codebook can provide information about the following: the structure of the data set (e.g., including one or more fields included in the data set and / or the length of each field), one or more data variables, one or more data identifiers and / or labels, one or more data generation formulas, one or more signal metrics, and / or one or more units of measurement. Example 400 includes a beam codebook 402 that provides information about a set of beams. For visual clarity, the beam codebook 402 shown in Example 400 has been simplified, and other examples of beam codebooks can include alternative or additional information.

[0066] In some aspects, the beam codebook 402 can indicate various information about each beam included in a set of beams, such as spatial information (e.g., beam width and / or beam direction) and / or beam relationship information (e.g., how a first beam is related to a second beam). As an example, the beam codebook 402 can be associated with a set of beams supported by UE hardware. As shown in Example 400, the beam codebook 402 can divide the set of beams into one or more spatial groups at least partially based on the transmit direction associated with each beam. In other words, each beam within a spatial group of beams can have a commensurate line-of-sight (LoS) transmit direction (e.g., each beam LoS transmit direction is within a range and / or threshold of the values of the other beams within the spatial group). Alternatively or additionally, the beam codebook 402 can indicate the beam hierarchical structure of each beam within a subset of beams.

[0067] For illustration, the beam codebook 402 may divide the set of beams into N subsets, where N is an integer. The first codebook index 404 (shown as index 0) may map to the first subset of beams shown in the first horizontal row of the beam codebook 402, the second codebook index 406 (shown as index 1) may map to the second subset of beams shown in the second horizontal row of the beam codebook 402, and the third codebook index 408 (shown as index 2) may map to the third subset of beams shown in the third horizontal row of the beam codebook 402. As shown in example 400, the (N−1)th codebook index 410 (shown as index N−1) may map to the Nth subset of beams shown in the bottom horizontal row of the beam codebook 402. In some aspects, the beam codebook 402 may group and / or index subsets of beams at least in part based on spatial relationships. For example, the overall set of beams associated with the beam codebook 402 may collectively have a 360-degree horizontal coverage area, and the beam codebook 402 may divide each subset of beams at least in part based on LoS transmission directions that are integer multiples of 360 / N. Stated another way, the first subset of beams may be associated with a first horizontal LoS transmission direction of 0 degrees, the second subset of beams may be associated with a second horizontal LoS transmission direction of 360 / N degrees, the third subset of beams may be associated with a third horizontal LoS transmission direction of (360 / N)*2 degrees, up to the Nth subset of beams being associated with an Nth LoS transmission direction of (360 / N)*(N−1) degrees. Although described as horizontal LoS transmission directions, other examples may alternatively or additionally be at least in part based on other metrics of the transmission direction, such as vertical LoS transmission directions and / or vector-based LoS transmission directions.

[0068] In some aspects, the beam codebook 402 may index a subset of beams by at least partially assigning consecutive index values to a subset of beams having neighboring LoS transmission directions. By way of illustration, the beam codebook 402 may assign a codebook index (e.g., a second codebook index 406) consecutive to the first codebook index 404 to a second subset of beams based at least in part on the second subset of beams having a LoS transmission direction neighboring that of the first subset of beams (e.g., based at least in part on a 360 / N division). The neighboring subsets of beams and / or the beams within a subset may alternatively be referred to as adjacent subsets of beams (and / or adjacent beams). Thus, the second subset of beams indicated by the second codebook index 406 may be referred to as a subset of beams adjacent to a first subset of beams (e.g., indicated by the first codebook index 404) and a third subset of beams (e.g., indicated by the third codebook index 408). Alternatively or additionally, individual beams may be referred to as adjacent beams. By way of illustration, a first individual beam (e.g., beam 2) within the second subset of beams may be referred to as adjacent to a second individual beam (e.g., beam 1) within the first subset of beams and / or a third individual beam (e.g., beam 3) within the third subset of beams based at least in part on each beam being within an adjacent subset and each beam having a common hierarchical structure as further described.

[0069] In some aspects, the beam codebook 402 may indicate a beam hierarchical structure of the beams within a subset of beams, the beam hierarchical structure being based at least in part on the spatial width of each beam. For example, the beam codebook 402 may indicate that a first beam (shown as beam 1) having the largest spatial width within a first subset of beams is assigned a "level 1" hierarchical structure as shown by reference numeral 412. The beam codebook 402 may indicate that a second beam (shown as beam N+1) having a (e.g., relative to the first beam) second widest spatial width within the first subset of beams is assigned a "level 2" hierarchical structure as shown by reference numeral 414, and that a third beam (shown as beam (N*2)+1) having a (e.g., relative to the second beam) second widest spatial width within the first subset of beams is assigned a "level 3" hierarchical structure as shown by reference numeral 416. Thus, a lower numerical value in the beam hierarchical structure may indicate a wider beam width and / or a higher hierarchical structure level. A higher numerical value in the beam hierarchical structure may indicate a narrower beam width and / or a lower hierarchical structure level. For example, and as shown in example 400, beam 1 has a wider beam width and a higher hierarchical structure level relative to beam N+1 and beam (N*2)+1. Beam N+1 has a wider beam width and a higher hierarchical structure level relative to beam (N*2)+1, but has a narrower beam width and a lower hierarchical structure level relative to beam 1. Beam (N*2)+1 has a narrower beam width and a lower hierarchical structure level relative to beam 1 and beam N+1.

[0070] A "parent beam" in a beam hierarchy may represent a beam that has a beam hierarchy that is adjacent to and higher than another beam and subsequently has a wider beam width. For example, beam 1 may be referred to as the parent beam of beam N+1 at least in part based on beam 1 having a beam hierarchy (e.g., level 1) that is adjacent to and higher than beam N+1 (e.g., having a level 2 beam hierarchy). Alternatively or additionally, beam N+1 may be referred to as a "child beam" of beam 1 at least in part based on having a beam hierarchy that is adjacent to and lower than the beam hierarchy of beam 1. Beam 1 may include beam N+1 at least in part based on beam 1 and beam N+1 being grouped in the same subset of beams and having commensurate LoS transmission directions, provided that a first transmission coverage area associated with beam 1 may encompass a second transmission coverage area associated with beam N+1. Beam N+1 may be referred to as the parent beam of beam (N*2)+1, and beam (N*2)+1 may be referred to as the child beam of beam N+1. While example 400 shows a single child beam associated with a parent beam, other examples may include multiple child beams associated with the same parent beam.

[0071] A first beam in a first subset of beams may be considered an adjacent beam to a second beam in a second subset of beams at least in part based on the beams having the same beam hierarchy and being in adjacent subsets of beams (e.g., having adjacent LoS transmission directions). By way of illustration, and with respect to a level 1 beam hierarchy as shown by reference numeral 412, beam 1 in a first subset of beams may be considered adjacent to beam 2 and beam N, and beam 2 may be considered adjacent to both beam 1 and beam 3. Again, beam N+2 in a second subset of beams may be considered adjacent to beam N+3 in a third subset of beams and beam N+1 in a first subset of beams. However, beam N+1 may not be considered adjacent to beam N+3 at least in part based on the beams being in non-adjacent subsets.

[0072] As described above, a UE (e.g., UE 120) may perform beam management procedures at least in part based on a beam codebook (e.g., a UE beam codebook). For example, the UE may use a cyclic procedure to scan each beam indicated by the beam codebook, in which the UE continuously scans each beam for equal time periods. However, scanning each beam may introduce a time delay that is disproportionate to the benefits of scanning each beam. For illustration, some receive beams may be associated with a LoS direction orthogonal to the transmission source direction. As another example, the UE may scan a static subset of beams, which may cause the UE to select a beam that has a relatively high signal quality (e.g., a local maximum within the subset) but not the highest signal quality within the overall set of beams indicated by the beam codebook. For illustration, the UE may perform beam management procedures at least in part based on a static subset of beams (e.g., a static number of beams and / or a static combination of beams) in the presence of signal blockage at the antenna. However, the static subset of beams may be at least in part based on a primary beam selected in the absence of signal blockage (e.g., a beam having the highest signal quality relative to other beams). For illustration, the static combination of beams may be a static list that specifies beams to be selected at least in part based on beam relationships and / or a beam hierarchy relative to the primary beam (e.g., the beam relationships and / or the beam hierarchy remain static). In such scenarios, the UE may select a first beam from the static subset of beams as a local maximum selection (e.g., rather than the best selection from the overall set of available beams), which may result in a reduced signal quality relative to a second beam from the set of beams indicated by the beam codebook. The reduced signal quality may result in increased recovery errors, reduced data throughput, and / or increased data transfer latency.

[0073] Some of the techniques and apparatus described herein provide beam scanning based on a user equipment operating state. In some aspects, a UE may perform a beam scanning procedure that selects a communication beam for communication in a wireless network. As part of performing the beam scanning procedure, the UE may dynamically select a beam scanning subset of beams from a plurality of beams at least in part based on a current UE operating state. In some aspects, selecting the beam scanning subset of beams may include: selecting a number of beams to be included in the beam scanning subset of beams at least in part based on the current UE operating state, such as selecting a greater number of beams for a first UE operating state and a lesser number of beams for a second UE operating state. Alternatively or additionally, selecting the beam scanning subset of beams may include: selecting beams to be included in the beam scanning subset of beams at least in part based on one or more sub-lists of beams and / or a beam hierarchy. The UE may communicate in the wireless network at least in part using the communication beam selected using the beam scanning procedure.

[0074] By dynamically selecting the beams used in a beam scanning procedure based at least in part on the current UE operating state, the UE can dynamically change the number and / or combination of beams in a beam scan subset of beams and improve the beam management procedure. For example, the UE can select fewer beams (e.g., relative to a static number of beams) and reduce the latency associated with performing the beam management procedure based at least in part on identifying that the beam management procedure may be performed more frequently based on the UE rapidly changing position. Alternatively or additionally, the UE can change the combination of beams such that the UE can select the best beam from the overall set of available beams based at least in part on identifying that the UE is stationary and the beam management procedure may be performed less frequently, rather than selecting a local maximum beam from a static list of beams. Dynamically changing the subset of beams based on the UE operating state can enable the UE to optimize the tradeoff between reducing the latency associated with performing the beam scan procedure and improving the signal quality associated with the selected beams. Optimizing this tradeoff can further reduce recovery errors, increase data throughput, and / or reduce data transfer latency.

[0075] As indicated above, Figure 4 is provided as an example. Other examples may be different from the example described with respect to Figure 4 is described.

[0076] Figure 5 FIG. 500 is a diagram illustrating an example 500 of a wireless communication procedure between a network node (e.g., network node 110) and a UE (e.g., UE 120) in accordance with the present disclosure.

[0077] As shown by reference numeral 510, network node 110 may send a beam management procedure command, and UE 120 may receive the beam management procedure command. For example, network node 110 may generate a first signal metric based at least in part on an uplink signal from UE 120 and / or receive a second signal metric from UE 120 that is based at least in part on downlink communication from network node 110. The first signal metric and / or the second signal metric may indicate that the signal quality associated with the beam(s) used by network node 110 and / or UE 120 for communication has dropped below a quality threshold, and the network node may determine to initiate a beam management procedure.

[0078] As an example, the network node may send any combination of an RRC message, a MAC CE, and / or DCI that indicates the performance of a beam management procedure (e.g., as described with respect to Figure 3(the described first beam management procedure, second beam management procedure, and / or third beam management procedure). Alternatively or additionally, network node 110 may indicate a configuration associated with the beam management procedure, such as a reference signal configuration (e.g., air interface resources, ports, and / or periodicity), the type of measurements to be performed, the beam management procedure start time, the beam management procedure stop time, and / or the reporting configuration. However, in other examples, network node 110 may avoid sending a beam management procedure command and send an indication of one or more occurrences of the reference signal in a broadcast message.

[0079] As shown by reference numeral 520, UE 120 may determine the current UE operating state. For example, UE 120 may determine any combination of a UE motion state (e.g., fast motion state, slow motion state, and / or stationary state), a Doppler factor, and / or a beam dwell time. By way of illustration, UE 120 may determine the current rate and / or speed of the UE to track position changes at least in part based on a Global Navigation Satellite System (GNSS) receiver. In some aspects, UE 120 may identify the current UE motion state based on one or more thresholds such as a stationary threshold indicating that the UE is stationary, a slow motion threshold indicating that the UE is moving at a slow rate, and / or a fast motion threshold indicating that the UE is moving at a fast rate. For example, UE 120 may determine that the UE is currently operating in the stationary state at least in part based on identifying that the current UE speed (e.g., determined at least in part based on the GNSS receiver) meets the stationary threshold (e.g., the UE speed is below or at the stationary threshold). As another example, UE 120 may determine that the UE is currently operating in the slow motion state at least in part based on determining that the current UE speed meets the slow motion threshold (e.g., the UE speed is above the stationary threshold and / or at or above the slow motion threshold). In some scenarios, UE 120 may determine that the UE is currently operating in the fast motion state at least in part based on determining that the current UE speed meets the fast motion threshold (e.g., the UE speed is above the slow motion threshold and / or at or above the fast motion threshold). Thus, the stationary threshold, the slow motion threshold, and the fast motion threshold may indicate different rates and / or speeds. The values assigned to each motion threshold may be indicated to UE 120 by network node 110 (e.g., in RRC signaling), and / or may be stored statically at UE 120.

[0080] As another example, the Doppler factor may indicate the movement of UE 120 relative to network node 110. For illustration, UE 120 may measure the Doppler frequency based at least in part on a downlink reference signal from network node 110. In some aspects, UE 120 may determine a high relative change in movement (e.g., between the UE and the network node), a low relative change in movement, and / or a minimal to no relative change in movement as a UE operating state. A high Doppler frequency and / or a rapid change between Doppler frequencies may indicate a greater relative change in movement, and a low Doppler frequency may indicate a lesser relative change in movement. Thus, UE 120 may determine the current UE operating state based at least in part on a first Doppler threshold indicating a high relative change in movement, a second Doppler threshold indicating a low relative change in movement, and / or a third Doppler threshold indicating a minimal to no relative change in movement. The values assigned to each Doppler threshold may be indicated to UE 120 by network node 110 (e.g., in RRC signaling), and / or may be stored statically at UE 120.

[0081] "Beam dwell time" may represent the amount of time that UE 120 uses a particular beam as the primary beam (e.g., without switching to another beam) to communicate with network node 110. A long beam dwell time may indicate that UE 120 is using the same beam and may thus be in a stationary state. A short beam dwell time may indicate that UE 120 may change the primary beam relatively quickly (e.g., relative to a long beam dwell time), and may indicate that UE 120 is operating in a slow movement and / or fast movement state. Thus, UE 120 may determine the current UE operating state based at least in part on a first dwell time threshold indicating a fast movement state, a second dwell time threshold indicating a slow movement state, and / or a third dwell time threshold indicating a stationary state. The values assigned to each dwell time threshold may be indicated to UE 120 by network node 110 (e.g., in RRC signaling), and / or may be stored statically at UE 120.

[0082] As shown by reference numeral 530, UE 120 may select a beam scan subset of beams for a beam management procedure. For illustration, UE 120 may select beams that are part of a beam scan procedure included in the beam management procedure. In some aspects, UE 120 may select a beam scan subset of beams based at least in part on the current UE operating state. For example, UE 120 may select a beam scan subset of beams from among a plurality of beams indicated in the UE beam codebook, such as with respect to Figure 4The described beam codebook. When selecting a beam scanning subset of beams, the UE can dynamically select the number of beams included in the beam scanning subset of a beam (e.g., more beams or fewer beams), such as by selecting more beams at least in part based on the current UE operating state indicating that the UE is operating in a stationary state and selecting fewer beams at least in part based on the current UE operating state indicating that the UE is operating in a fast-moving state. For illustration, the fast-moving state may indicate that a beam selected as the main beam at a first time point (e.g., at least in part based on the best signal quality) may not be applicable at a second time point at least in part based on the UE's moving position. In other words, sweeping over more beams may increase the time associated with the beam management procedure at least in part because the UE moves positions faster when operating in the fast-moving state, with less benefit (e.g., the beam with the best signal quality may change relatively quickly based on the UE's moving position). The increased time associated with using more beams may provide more benefit to the UE operating in the stationary state at least in part because the UE position remains unchanged (e.g., the beam with the best signal quality is less likely to change).

[0083] As an example, the plurality of beams indicated in the UE beam codebook can be divided into one or more spatial groups of beams, as further described with respect to Figure 4 The UE 120 can select a beam scanning subset of beams at least in part based on the current UE operating state and the one or more spatial groups of the beam, such as by selecting the number of beams that are spatially related to the main beam. As an example, the UE 120 can receive a plurality of different reference signals (e.g., SSB), and select a corresponding main beam for each reference signal at least in part based on a signal metric that indicates that the corresponding main beam has a higher signal quality relative to other beams. In some aspects, for each main beam, the UE 120 can select a corresponding beam scanning subset of the beam at least in part based on the corresponding main beam. In other words, the UE 120 can select a plurality of beam scanning subsets of the beam, and each beam scanning subset of the beam can be at least in part based on the corresponding main beam associated with the corresponding reference signal.

[0084] As described with respect to Figure 4Further described, the primary beam selected by the UE 120 may be associated with a baseline beam hierarchical level (e.g., level 1, level 2, and / or level 3) within a spatial grouping of beams. In some aspects, the UE 120 may select a beam scan subset of the beams associated with the primary beam at least in part based on the baseline beam hierarchical level and one or more sub-lists of the beams. In other words, in addition to the spatial grouping indicated by the UE beam codebook, the UE 120 may also divide the plurality of beams into one or more sub-lists based at least in part on beam hierarchical relationships and / or spatial relationships. By way of illustration, an example first sub-list of the beams may include the primary beam associated with a corresponding reference signal and / or other primary beams associated with other reference signals. An example second sub-list of the beams may include the parent-level beam associated with the corresponding primary beam, each adjacent-level beam associated with the corresponding primary beam, and each sub-level beam associated with the corresponding primary beam.

[0085] Alternatively or additionally, the second sub-list of the beams may include the parent-level beam, each adjacent-level beam, and each sub-level beam associated with other primary beams associated with other reference signals. An example third sub-list of the beams may include each parent-adjacent-level beam (e.g., the parent-level beam in one or more neighboring spatial groupings) associated with the corresponding primary beam. In some aspects, the example third sub-list of the beams may include each parent-adjacent-level beam associated with other primary beams associated with other reference signals. An example fourth sub-list of the beams may include each sub-adjacent-level beam (e.g., the sub-level beam in one or more neighboring spatial groupings) associated with the corresponding primary beam and / or each sub-adjacent-level beam associated with other primary beams associated with other reference signals. An example fifth sub-list of the beams may include all level 1 beams among the plurality of beams included in the UE beam codebook, and an example sixth sub-list of the beams may include all maximum-level beams among the plurality of beams. In some aspects, the level 1 beams may be based at least in part on an absolute value, while the maximum-level beams may be based at least in part on a relative value. For example, the level 1 beams may represent the beams assigned to the level 1 hierarchical structure specified by a beam hierarchy (e.g., an absolute beam width threshold), and the maximum-level beams may be the beams within the spatial grouping with the highest beam hierarchy. Thus, the maximum-level beams may have a lower beam hierarchy relative to level 1, such as the maximum-level beams in a spatial grouping lacking level 1 beams.

[0086] In one example, the UE 120 may select a first sub-list of beams, a second sub-list of beams, and a fifth sub-list of beams as a beam scanning subset of the beams. For illustration, the UE 120 may select the first sub-list, the second sub-list, and the fifth sub-list at least in part based on a current UE operating state that includes a beam dwell time that meets a first dwell time threshold (e.g., associated with a fast motion state), a Doppler factor and / or Doppler frequency that meets a first Doppler threshold (e.g., associated with a high relative change in motion), and / or a UE motion state that meets a fast motion threshold. In other words, the UE 120 may determine to include a smaller number of beams (e.g., relative to other UE operating states and / or other beam scanning subsets) in the beam scanning subset at least in part based on determining that the UE is operating in a fast motion state and that beam management procedures may be used more frequently as the UE moves positions more quickly.

[0087] As another example, the UE 120 may select a first sub-list of beams, a second sub-list of beams, a third sub-list of beams, a fourth sub-list of beams, and a fifth sub-list of beams as a beam scanning subset of the beams. For example, the UE 120 may select the first sub-list, the second sub-list, the third sub-list, the fourth sub-list, and the fifth sub-list at least in part based on a current UE operating state that includes a beam dwell time that meets a second dwell time threshold (e.g., associated with a slow motion state), a Doppler factor and / or Doppler frequency that meets a second Doppler threshold (e.g., associated with a slow motion state), and / or a UE motion state that meets a slow motion threshold. In some aspects, the UE 120 may select a greater number of beams to include in the beam scanning subset (e.g., relative to a "fast motion" beam scanning subset of the beams) at least in part based on identifying that the UE 120 is changing positions less quickly relative to a fast motion UE operating state and subsequently determining that a selected primary beam may be used for a longer period of time. Thus, using a greater number of beams in the beam scanning subset may improve the signal quality of the selected beams and / or reduce the frequency at which the network node 110 and the UE 120 perform beam management procedures. Reducing the frequency of beam management procedure execution may reduce the latency introduced by performing the beam management procedures.

[0088] As another example, the UE 120 may select the first sub - list of beams, the second sub - list of beams, the third sub - list of beams, the fourth sub - list of beams, the fifth sub - list of beams, and the sixth sub - list of beams as the beam scanning subset of beams. For example, the UE 120 may select the first sub - list, the second sub - list, the third sub - list, the fourth sub - list, the fifth sub - list, and the sixth sub - list of beams at least in part based on the current UE operating state including a UE motion state that meets a stationary threshold. The UE 120 may select more beams (e.g., relative to a "fast - motion" beam scanning subset of beams and / or a "slow - motion" beam scanning subset of beams) to be included in the beam scanning subset at least in part based on identifying that the UE 120 is stationary and subsequently determining that the selected main beam can be used for a longer period of time. Thus, using more beams in the beam scanning subset of beams can improve the signal quality of the selected beams. Alternatively or additionally, the network node 110 and / or the UE 120 may perform beam management procedures less frequently based on the improved signal quality, and subsequently reduce the latency introduced by performing the beam management procedures.

[0089] As shown by reference numeral 540, the network node 110 and the UE 120 may perform beam management procedures. As an example, the network node 110 and the UE 120 may perform any combination of beam management procedures as further described with respect to Figure 3 In some aspects, the UE 120 may use a beam scanning subset of beams selected at least in part based on the current UE operating state.

[0090] As shown by reference numeral 550, the UE 120 may send an indication of the selected beam, and the network node 110 may receive the indication. For example, the UE 120 may select a different beam at least in part based on the beam management procedure indicating that the different beam has a higher signal quality relative to the current beam. The UE 120 may indicate the different beam at least in part based on an RRC message, a MAC CE, and / or uplink control information (UCI).

[0091] By dynamically selecting the beams used in a beam scanning procedure at least in part based on the current UE operating state, the UE can dynamically change the number and / or combination of beams in a beam scan subset of beams and improve the beam management procedure. For example, the UE can select fewer beams (e.g., relative to a static number of beams), and at least in part based on (e.g., by identifying that the UE is changing position rapidly) identify that the beam management procedure can be performed more frequently to reduce the latency associated with performing the beam management procedure. Alternatively or additionally, the UE can change the combination of beams, which enables the UE to select the best beam from the overall set of available beams at least in part based on (e.g., by identifying that the UE is stationary) identifying that the beam management procedure can be performed less frequently. Dynamically changing the subset of beams based on the UE operating state can enable the UE to optimize the tradeoff between reducing the latency associated with performing the beam scan procedure and improving the signal quality associated with the selected beams. Optimizing this tradeoff can further reduce recovery errors, increase data throughput, and / or reduce data transfer latency.

[0092] As indicated above, Figure 5 is provided as an example. Other examples may be different from the examples described with respect to Figure 5 the examples described.
