[0001] Cross-reference to related applications

[0002] This application claims the benefit of U.S. Non-Provisional Patent Application Serial No. 18 / 452,501, filed August 18, 2023, entitled “SCHEDULING WITH A SPLIT SYMBOL FOR BEAM MANAGEMENT”, the entire contents of which are expressly incorporated herein by reference. Technical Field

[0003] This disclosure relates generally to communication systems, and more specifically to wireless communication utilizing beam management. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the city, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Evolution of Mobile Broadband (CEM) program issued by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT),) and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. Furthermore, these improvements can also be applied to other multiple access technologies and telecommunications standards that adopt these technologies. Summary of the Invention

[0006] The following is a simplified summary of one or more aspects to provide a basic understanding of these aspects. This summary is not a comprehensive overview of all conceived aspects. It neither identifies key or essential elements of all aspects nor describes the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed descriptions that follow.

The apparatus is also configured to communicate with the network node using the first beam or the second beam based on at least one of the first measurement or the second measurement.

[0008] In this respect, the method includes: receiving DL signaling from a network node, the DL signaling including a symbol located in a first time slot of the DL signaling. The method further includes: measuring a first measurement of a first beam at the UE during a first time portion of the symbol, and measuring a second measurement of a second beam at the UE during a second time portion of the symbol different from the first time portion.

[0025] Wireless communication networks (such as 5G NR networks and other examples of wireless communication networks) can be designed to support beam management for communication between network nodes (e.g., base stations, gNBs, etc.) and UEs. In some examples, the UE can measure a single beam within each symbol, for example, using a demodulation reference signal (DMRS) of the physical broadcast channel (PBCH) received in the symbol. If the PBCH is transmitted in two of the three symbols in a synchronization signal block (SSB), and there are secondary synchronization signals (SSS) (e.g., PBCH, SSS, PBCH) or their burst sets between the two PBCHs, the UE can measure three beams on the three symbols of the SSB. In some aspects, one-time beam management (OSBM) and channel impulse response-based dynamic beaming (DYB) can manage beams using estimations of the channel correlation R matrix.

[0026] However, such solutions can be inefficient in terms of latency and / or accuracy. That is, the single-beam-per-symbol approach utilizes multiple SSBs to measure the beam of a five-element antenna module, and using two SSBs to estimate the R-matrix of such an antenna module can result in estimates that may be affected by channel variations associated with fading and / or UE mobility over the time length of time multiple SSBs are received. For example, the delay measured on the second SSB may be susceptible to fading channels or UE mobility, and the correlation of the R-matrix may be estimated under degraded conditions. Degradation in the estimation can impact beam tracking performance.

[0027] Various aspects as a whole relate to wireless communication systems utilizing beam management. Some aspects more specifically relate to scheduling using split symbols for beam management. In one example, a UE may be configured to receive DL signaling from a network node, the DL signaling including symbols located in a first time slot of the DL signaling. The UE may be configured to measure a first measurement of a first beam at the UE during a first time portion of the symbol, and a second measurement of a second beam at the UE during a second time portion of the symbol, different from the first time portion. The UE may also be configured to communicate with the network node using either the first or second beam based on at least one of the first or second measurements.

[0028] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In one example, the described techniques can be used to achieve up to six beam measurements per SSB (e.g., based on a single received SSB) by splitting the measured symbol into two halves or portions (where each portion can be used to measure one beam). In another example, measuring up to six beams per SSB increases beam management speed, resulting in reduced latency and associated effects. For example, reduced latency in beam measurement can help mitigate measurement or estimation inaccuracies due to rotation, fading, and / or UE mobility. Thus, improvements in the utilization of OSBM and DYB specific implementations can be achieved by generating a DYB with improved accuracy within a single SSB by estimating the Reference Signal Received Power (RSRP) of all static beams.

[0029] The detailed descriptions following, illustrated with reference to the accompanying drawings, describe various configurations and do not represent the only configurations in which the concepts described herein can be practiced. To provide a thorough understanding of the various concepts, the detailed descriptions include specific details. However, these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0030] Various apparatuses and methods are presented with reference to several aspects of a telecommunications system. These apparatuses and methods are described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0031] As an example, an element, any part of an element, or any combination of elements may be implemented as a "processing system" including one or more processors. When multiple processors are implemented, the multiple processors may perform functions individually or in combination. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. One or more processors in the processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, or any combination thereof.

[0032] Therefore, in one or more example aspects, specific implementations, and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available medium accessible to a computer. By way of example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage devices, magnetic disk storage devices, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures accessible to a computer.

[0033] While aspects, implementations, and / or use cases are described herein by way of example, additional or different aspects, implementations, and / or use cases may arise in many different arrangements and scenarios. The aspects, implementations, and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, aspects, implementations, and / or use cases may arise via integrated chip implementations and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to a use case or application, the described examples may exhibit broad applicability. Aspects, implementations, and / or use cases can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the technologies described herein. In some practical settings, devices incorporating the described aspects and features may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The techniques described herein can be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or decomposed components, end-user equipment, etc., of various sizes, shapes, and configurations.

[0034] Communication systems, such as 5G NR systems, can be deployed in various ways with a variety of components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, radio access network (RAN) nodes, core network nodes, network elements or network equipment (such as base stations (BS)), or one or more units (or components) performing base station functions can be implemented in aggregated or decomposed architectures. For example, BSs (such as Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), transmit / receive point (TRP), or cell, etc.) can be implemented as aggregated base stations (also known as standalone BS or monolithic BS) or decomposed base stations.

[0035] Aggregated base stations can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. Decentralized base stations can be configured to utilize a protocol stack that is physically or logically distributed across two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, the CU may be implemented within a RAN node, and one or more DUs may co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other RAN nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may be implemented as a virtual unit, namely a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0036] Base station operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in Integrated Access Backhaul (IAB) networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)). Decomposition can include distributing functionality across two or more units in various physical locations, as well as virtually distributing the functionality of at least one unit, which enables flexibility in network design. The various units of a decomposed base station or decomposed RAN architecture can be configured to communicate wirelessly with at least one other unit.

[0037] Figure 1 Figure 100 illustrates an example of a wireless communication system and access network. The illustrated wireless communication system includes a decomposed base station architecture. The decomposed base station architecture may include one or more CUs 110, which may communicate directly with the core network 120 via a backhaul link, or indirectly with the core network 120 via one or more decomposed base station units, such as a near real-time (near-RT) RAN Intelligent Controller (RIC) 125 via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a Service Management and Orchestration (SMO) framework 105, or both. CUs 110 may communicate with one or more DUs 130 via a corresponding midhaul link (such as an F1 interface). DUs 130 may communicate with one or more RUs 140 via a corresponding fronthaul link. RUs 140 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0038] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO frame 105) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of these units, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally, these units may include wireless interfaces that may include receivers, transmitters, or transceivers (such as RF transceivers) configured to receive signals via wireless transmission media and / or transmit signals to one or more other units.

[0039] In some aspects, the CU 110 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 110. The CU 110 can be configured to handle user plane functionality (i.e., Central Unit-User Plane (CU-UP)), control plane functionality (i.e., Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 110 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 110 can be implemented to communicate with the DU 130 for network control and signaling, as needed.

[0040] DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 140s. In some aspects, DU 130 may at least partially host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation, demodulation, etc.) according to functional splits (such as those defined by 3GPP). In some aspects, DU 130 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0041] Lower-layer functionality can be implemented by one or more RU 140s. In some deployments, an RU140 controlled by a DU 130 may correspond to a logical node that at least partially hosts RF processing functions or low-PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, etc.) based on functional decomposition such as lower-layer functional decomposition, or both. In this architecture, the RU 140 can be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration allows the DU 130 and CU 110 to be implemented in cloud-based RAN architectures such as vRAN architectures.

[0042] SMO framework 105 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 105 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, SMO framework 105 can be configured to interact with a cloud computing platform such as Open Cloud (O-Cloud) 190 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 110, DU 130, RU 140, and near-RT RIC 125. In some implementations, SMO framework 105 can communicate with hardware aspects of the 4G RAN, such as Open eNB (O-eNB) 111, via the O1 interface. Additionally, in some implementations, SMO framework 105 can communicate directly with one or more RU 140s via the O1 interface. SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of SMO framework 105.

[0043] The non-RT RIC 115 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence (AI) / machine learning (ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 125. The non-RT RIC 115 can be coupled to or communicate with the near-RT RIC 125, such as via an A1 interface. The near-RT RIC 125 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface such as an E2 interface, connecting one or more CU 110s, one or more DU 130s, or both, and O-eNBs to the near-RT RIC 125.

[0044] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 125 and can be received from non-network data sources or network functions at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 105 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0045] At least one of CU 110, DU 130, and RU 140 may be referred to as base station 102. Therefore, base station 102 may include one or more of CU 110, DU 130, and RU 140 (each component is indicated by a dashed line to indicate that each component may or may not be included in base station 102). Base station 102 provides UE 104 with an access point to core network 120. Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Small cells include femtocells, picocells, and microcells. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include an evolved home node B (eNB) (HeNB), which can provide service to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) transmission (also known as reverse link) from UE 104 to RU 140 and / or downlink (DL) transmission (also known as forward link) transmission from RU 140 to UE 104. The communication link may utilize multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (x component carriers) for transmission in each direction, base station 102 / UE 104 may use a spectrum with a bandwidth of up to Y MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.). Carriers may be adjacent to each other or may not be adjacent to each other. Carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier can be referred to as the primary cell (PCell) and the secondary component carrier can be referred to as the secondary cell (SCell).

[0046] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL wireless wide area network (WWAN) spectrum. D2D communication link 158 can use one or more sidelink channels, such as Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be performed through various wireless D2D communication systems, such as Bluetooth. ™ (Bluetooth is a trademark of the Bluetooth Special Interest Group (SIG), and is based on the IEEE 802.11 standard for Wi-Fi.) ™(Wi-Fi is a trademark of the Wi-Fi Alliance), LTE, or NR.

[0047] The wireless communication system may also include a Wi-Fi AP 150, which communicates with the UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the UE 104 / AP 150 may perform a free channel assessment (CCA) to determine whether the channel is available before communication.

[0048] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). Although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the "sub-6GHz" band. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this is distinct from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0049] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as the frequency range designations FR2-2 (52.6 GHz to 71 GHz), FR4 (71 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0050] In view of the above, unless otherwise specifically stated, the term "below 6 GHz" as used herein can broadly refer to frequencies less than 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, the term "millimeter wave" as used herein can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR2-2 and / or FR5, or within the EHF band.

[0051] Base station 102 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. Base station 102 may transmit beamformed signals 182 to UE 104 in one or more transmit directions. UE 104 may receive beamformed signals from base station 102 in one or more receive directions. UE 104 may also transmit beamformed signals 184 to base station 102 in one or more transmit directions. Base station 102 may receive beamformed signals from UE 104 in one or more receive directions. Base station 102 / UE 104 may perform beamforming training to determine the optimal receive and transmit directions for each of base station 102 / UE 104. The transmit and receive directions of base station 102 may be the same or different. The transmit and receive directions of UE 104 may be the same or different.

[0052] Base station 102 may include and / or be referred to as gNB, Node B, eNB, access point, transceiver base station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), TRP, network node, network entity, network equipment, or some other suitable terminology. Base station 102 may be implemented as an integrated access and backhaul (IAB) node, relay node, sidelink node, aggregated (monolithic) base station with baseband units (BBU) (including CU and DU) and RU, or may be implemented as a decomposed base station including one or more of CU, DU, and / or RU. A collection of base stations that may include decomposed base stations and / or aggregated base stations may be referred to as Next Generation (NG) RAN (NG-RAN).

[0053] The core network 120 may include Access and Mobility Management Function (AMF) 161, Session Management Function (SMF) 162, User Plane Function (UPF) 163, Unified Data Management (UDM) 164, one or more location servers 168, and other functional entities. AMF 161 is the control node that handles signaling between UE 104 and the core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports authentication and key agreement (AKA) credential generation, user identity processing, access authorization, and subscription management. One or more location servers 168 are exemplified as including a Gateway Mobile Location Center (GMLC) 165 and a Location Management Function (LMF) 166. However, generally, one or more location servers 168 may include one or more location / positioning servers, which may include one or more of GMLC 165, LMF 166, Position Determination Entity (PDE), Serving Mobile Location Center (SMLC), Mobile Location Center (MPC), etc. GMLC 165 and LMF 166 support UE location services. GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE location information. LMF 166 receives measurement and auxiliary information from NG-RAN and UE 104 via AMF 161 to calculate the location of UE 104. NG-RAN may use one or more positioning methods to determine the location of UE 104. Positioning UE 104 may involve signal measurement, location estimation, and optional speed calculation based on these measurements. Signal measurement may be performed by UE 104 and / or base station 102 serving UE 104. The measured signals may be based on one or more of the following systems / signals / sensors: Satellite Positioning System (SPS) 170 (e.g., one or more of Global Navigation Satellite System (GNSS), Global Positioning System (GPS), Non-Terrestrial Network (NTN) or other position / location systems), LTE signals, Wireless Local Area Network (WLAN) signals, Bluetooth signals, Terrestrial Beacon System (TBS), sensor-based information (e.g., barometric pressure sensor, motion sensor), NR Enhanced Cell ID (NR E-CID) method, NR signals (e.g., multiple round-trip time (multiple RTT), DL departure angle (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning) and / or other systems / signals / sensors.

[0054] Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet devices, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional device. Some UEs in UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, mobile phone, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more companion devices, such as in a device constellation arrangement. One or more of these devices may access the network together and / or individually.

[0055] Refer again Figure 1 In some aspects, UE 104 may have a split-symbol scheduling component 198 (“Component 198”), which is configured to receive DL signaling from a network node, the DL signaling including symbols located in a first timeslot of the DL signaling. Component 198 may also be configured to measure a first measurement of a first beam at the UE during a first time portion of a symbol, and a second measurement of a second beam at the UE during a second time portion of a symbol different from the first time portion. Component 198 may also be configured to communicate with the network node using the first beam or the second beam based on at least one of the first measurement or the second measurement. Component 198 may be configured to perform at least one of the following: estimating the RSRP of the first beam based on the first measurement or estimating the RSRP of the second beam based on the second measurement. Component 198 may be configured to communicate using a beam selected from the first beam or the second beam based on the estimated RSRP. Component 198 may be configured to switch from the first beam to the second beam before the end of the second time portion associated with the symbol. Component 198 can be configured to perform up to six measurements for up to six beams during a single SSB comprising three symbols, including the PBCH.

[0056] In some aspects, base station 102 may have a split symbol scheduling component 199 (“Component 199”) configured to operate in a manner consistent with Component 198. Component 199 may be configured to provide or transmit DL signaling to the UE, the DL signaling including symbols located in a first timeslot of the DL signaling. Component 199 may also be configured to communicate with the UE using a first beam or a second beam based on at least one of a first measurement or a second measurement, wherein the first measurement is a first beam measured at the UE during a first time portion of a symbol, and wherein the second measurement is a second beam measured at the UE during a second time portion of a symbol different from the first time portion.

[0057] Therefore, the aspects of scheduling for beam management utilizing split symbols described in this paper achieve the measurement of more than three beams per SSB by using portions of the symbols to measure the SSB. As an example, the aspects can achieve the measurement of six beams per SSB by splitting the measured symbols into two halves or portions (where each portion can be used to measure different beams). Additionally, beam management can be performed faster and latency and associated effects can be reduced because beam measurement mitigates rotation, fading, and / or UE mobility by measuring up to six beams per SSB. Thus, improvements in the utilization of OSBM and DYB implementations are achieved by estimating the RSRP of all static beams to generate a DYB with improved accuracy within a single SSB.

[0058] Figure 2A Figure 200 illustrates an example of the first subframe within a 5G NR frame structure. Figure 2B Figure 230 illustrates an example of a DL channel within a 5G NR subframe. Figure 2C Figure 250 is an example of a second subframe within a 5G NR frame structure. Figure 2D Figure 280 illustrates an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to either DL or UL) or Time Division Duplex (TDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to both DL and UL). Figure 2A , Figure 2CIn the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are both DL and UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The slot format is configured for the UE via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0059] Figures 2A to 2D The frame structure is illustrated, and aspects of this disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include micro-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each time slot may include 14 symbols, and for extended CP, each time slot may include 12 symbols. Symbols on the DL may be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL may be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and a parameter set. The parameter set defines the subcarrier spacing (SCS) (see Table 1). Symbol length / duration can be scaled with 1 / SCS.

[0060]

[0061] Table 1: Parameter Set, SCS, and CP

[0062] For a normal CP (14 symbols / slot), different parameter sets µ 0 through 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For an extended CP, parameter set 2 allows 4 slots per subframe. Therefore, for a normal CP and parameter set µ, there are 14 symbols / slot and 2... µ One time slot / subframe. Subcarrier spacing can be equal to ,in The parameter sets are 0 to 4. Therefore, the subcarrier spacing is 15 kHz for parameter set µ=0 and 240 kHz for parameter set µ=4. The symbol length / duration is negatively correlated with the subcarrier spacing. Figures 2A to 2D Examples of a normal frequency division multiplexing (CP) with 14 symbols per time slot and a parameter set of µ=2 with 4 time slots per subframe are provided. The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within the frame set, there may be one or more distinct bandwidth portions (BWPs) of frequency division multiplexing (see [link to relevant documentation]). Figure 2B Each BWP can have a specific set of parameters and CP (normal or extended).

[0063] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) extending for 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0064] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. RS may include demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0065] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbol of the RB. A PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in the PDCCH search space (e.g., the common search space, the UE-specific search space) during PDCCH monitoring timing on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. The Primary Synchronization Signal (PSS) may be located within symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identification. The SSS may be located within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the physical layer cell identification group number and radio frame timing. Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on this PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the System Frame Number (SFN) and the number of Restricted Blocks (RBs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted via the PBCH (such as System Information Blocks (SIBs)), and paging messages.

[0066] like Figure 2C As illustrated, some REs in the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the first or first two symbols of the PUSCH. Depending on whether a short or long PUCCH is transmitted and depending on the specific PUCCH format used, the PUCCH DM-RS can be transmitted in different configurations. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the comb teeth. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0067] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCIs.

[0068] Figure 3 This is a block diagram illustrating communication between base station 310 and UE 350 in the access network. In the DL, Internet Protocol (IP) packets can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functionality. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the delivery of upper-layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0069] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functionality associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transport channel, forward error correction (FEC) decoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-order phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols can then be split into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently combined using inverse fast Fourier transform (IFFT) to produce a physical channel carrying a stream of time-domain OFDM symbols. The OFDM stream is spatially pre-decoded to generate multiple spatial streams. Channel estimates from channel estimator 374 can be used to determine the decoding and modulation scheme, as well as for spatial processing. Channel estimates can be derived from reference signals transmitted by UE 350 and / or channel condition feedback. Each spatial stream can then be provided to different antennas 320 via a separate transmitter 318Tx. Each transmitter 318Tx can use the corresponding spatial stream to modulate a radio frequency (RF) carrier for transmission.

[0070] At UE 350, each receiver 354Rx receives signals via its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides that information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, along with the reference signal, are recovered and demodulated by determining the most probable signal constellation point transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. Subsequently, the soft decision is decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0071] The controller / processor 359 may be associated with at least one memory 360 storing program code and data. The at least one memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0072] Similar to the functionality described in conjunction with DL transmission performed by base station 310, controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connectivity, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with upper-layer PDU delivery, error correction via ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority ordering.

[0073] The TX processor 368 can use the channel estimate derived from the reference signal or feedback transmitted by the channel estimator 358 from the base station 310 to select an appropriate decoding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354Tx. Each transmitter 354Tx can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0074] UL transmission is processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318Rx receives signals via its corresponding antenna 320. Each receiver 318Rx recovers the information modulated onto the RF carrier and provides that information to RX processor 370.

[0075] The controller / processor 375 may be associated with at least one memory 376 storing program code and data. The at least one memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets between transport and logical channels. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0076] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform coupling. Figure 1 Various aspects of component 198. At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform combined Figure 1 The components of 199 in all aspects.

[0077] In wireless communication networks, beam management can improve communication between network nodes (e.g., base stations, gNBs, etc.) and UEs. In some examples, the UE can measure a single beam within each symbol, for example, using the PBCH DMRS / SSS received in the symbol. If the PBCH is transmitted in two of the three symbols in an SSB, and there is an SSS (e.g., PBCH, SSS, PBCH) or its burst set between the two PBCHs, the UE can measure three beams on the three symbols of the SSB. In some aspects, OSBMs and CIR-based DYBs can utilize the estimation of the channel-dependent R matrix to manage beams. However, such solutions can be inefficient in terms of latency and / or accuracy. That is, the single-beam-per-symbol approach utilizes multiple SSBs to measure the beam of a five-element antenna module, and using two SSBs to estimate the R matrix of such an antenna module can have estimates that may be affected by channel changes associated with fading and / or UE mobility over the length of time during which multiple SSBs are received. For example, the delay measured on the second SSB can be susceptible to fading channels or UE mobility, and the correlation of the R matrix may be estimated under degraded conditions. Degraded estimation can affect beam tracking performance.

[0078] Figure 4 Figure 400 illustrates an example of beam scheduling for measuring a beam for each symbol in each SSB set. Figure 400 shows an antenna module 402 comprising five antenna elements: element 1, element 2, element 3, element 4, and element 5. Antenna module 402 can be configured to measure the beam of each of the elements on two SSBs: SSB1 404 and SSB2 406.

[0079] As shown in the figure, SSB1 404 may include: a symbol including a master synchronization signal (PSS) 408, a first PBCH symbol 410, a symbol including an SSS 412, and a second PBCH symbol 414, each symbol representing a single symbol. Figure 2BAn example SSB is illustrated. SSB2 406 may include: a symbol having PSS 416, a first PBCH symbol 418, a symbol including SSS 420, and a second PBCH symbol 422, each symbol representing a single symbol. During the time of the first PBCH symbol 410, element 1 of antenna module 402 can be used to measure beam 411 by receiving and measuring the first PBCH symbol 410 using the antenna element (e.g., performing measurements on PBCH DMRS received from a network node in the first PBCH symbol of the SSB). During the time of SSS 412, element 2 of antenna module 402 can be used to measure beam 413 with respect to the symbol for SSS 412 (e.g., using antenna element 2 to perform measurements on PBCH DMRS received in the SSS symbol of the SSB). During the time of the second PBCH symbol 414, element 3 of antenna module 402 can be used to measure beam 415 with respect to the symbol for the second PBCH symbol 414 (e.g., using antenna element 3 to perform measurements on the PBCH DMRS received in the second PBCH symbol of the SSB). For each of the first PBCH symbol 410, SSS 412, and the second PBCH symbol 414, a single beam is measured for a single element of the antenna array in antenna module 402.

[0080] As shown in the figure, SSB2 406 may include PSS 416, a first PBCH symbol 418, SSS 420, and a second PBCH symbol 422, each symbol representing a single symbol. During the time of the first PBCH symbol 418, element 1 of antenna module 402 can be used for symbol measurement beam 419 with respect to the first PBCH symbol 418. During the time of SSS 420, element 4 of antenna module 402 can be used for symbol measurement beam 421 with respect to the SSS 420.

[0081] During the time of the second PBCH symbol 422, element 5 of antenna module 402 can be used to measure the beam 423 with respect to the symbol for the second PBCH symbol 422. For each of the first PBCH symbol 418, SSS 420 and the second PBCH symbol 422, a single beam is measured for a single element of the antenna array in antenna module 402, wherein there is a beam switching opportunity 428 for antenna module 402 between symbols rather than during the symbol.

[0082] R-matrix estimation 424 can be calculated / determined by a device (e.g., UE) to which antenna module 402 is part. R-matrix estimation 424 can be used with OSBM and / or CIR-based DYB to determine beam 426 and perform beam management for that beam. Beam 426 can be used for communication with base stations, gNBs, etc. As shown, a single beam can be measured per symbol, and two SSBs are utilized to calculate / determine R-matrix estimation 424. The additional delay introduced for the latter SSB (e.g., SSB2 406) can make R-matrix estimation 424 susceptible to channel changes due to rotation, fading, and / or device mobility, which can degrade performance.

[0083] For the aspects discussed herein, splitting a symbol into multiple parts (e.g., two halves) in the time domain allows for the measurement of multiple different beams during the same SSB symbol. The aspects discussed herein provide UE-specific beam management scheduling for split symbol measurements to achieve measurements of more than three beams per SSB by splitting the measured symbol into two or more halves (where each part of the SSB symbol can be used to measure a different beam). Additionally, beam management measurements and decisions can be performed more quickly and with reduced latency and associated effects because beam measurements mitigate rotation, fading, and / or UE mobility by measuring up to six beams per SSB. Therefore, improvements in the utilization of OSBM and DYB specific implementations are achieved by estimating the RSRP of all static beams to generate a DYB with improved accuracy within a single SSB.

[0084] Figure 5 Call flowchart 500 illustrates a wireless communication process in various aspects. Call flowchart 500 illustrates the scheduling of beam management using split symbols at a wireless device (e.g., UE 502) communicating with a network node (e.g., base station 504, such as a gNB or other type of base station, as shown). The aspects described for base station 504 can be performed by the base station in an aggregated form and / or by one or more components of the base station in a decomposed form. Additionally or alternatively, these aspects can be performed autonomously by UE 502, in addition to and / or as a substitute for the operation of base station 504. UE 502 can be configured to have an antenna module (not shown, but included for use in the figures described below), which may include multiple antenna elements (e.g., five antennas of an antenna module / array or another number of antennas).

[0085] In the illustrated aspect, UE 502 may be configured to receive DL signaling 506, and base station 504 may be configured to send / provide the DL signaling. For example, base station 504 may be configured with a reference signal for UE measurement. As an example, base station 504 may provide an indication of the time when an SSB will be sent and / or the time when the UE performs an SSB measurement. Figure 5 The example illustrates base station 504 sending information about a reference signal to UE 502 at 505. DL signaling 506 may include DL signals during one or more symbols. In various aspects, DL signaling may include one or more symbols located in the time slot of DL signaling 506, and in various aspects, may include symbols of the SSB (e.g., PSS symbol, first PBCH symbol, SSS symbol, and second PBCH symbol, such as in combination). Figure 2B (As described). The PBCH may include the DMRS, for example, as a reference signal to be measured by the UE 502. In some aspects, the base station may transmit the first PBCH during the first symbol period, the SSS during the second symbol period, and the second PBCH during the third symbol period. That is, the DL signaling 506 may include an SSB, which includes: a first symbol including the PBCH, a second symbol including the SSS and the PBCH, and a third symbol including the PBCH. In various aspects, the DL signaling 506 may correspond to the first, second, or third symbol of the SSB.

[0086] UE 502 can be configured to measure a first measurement of a first beam at UE 502 (at 508) during a first time portion of a symbol of DL signaling (e.g., SSB), and to measure a second measurement of a second beam at UE 502 during a second time portion of a symbol of DL signaling, the second portion of which differs from the first time portion. In other words, UE 502 can be configured to perform measurements (at 508) for multiple (e.g., two) beams during a single symbol of DL signaling (e.g., SSB). Therefore, if the UE uses the first half of a symbol to measure the first beam and the second half of a symbol to measure the second beam, UE 502 can be configured to perform up to six measurements for up to six beams during a single SSB comprising three symbols, including the Physical Broadcast Channel (PBCH). Regarding the measurability of up to six beams, the UE can perform individual measurements for each of the up to six beams. The beams measured (at 508) can each correspond to antenna elements of the antenna module / array of UE 502.

[0087] Furthermore, UE 502 can be configured to switch beams during a symbol period (e.g., split symbol scheduling) to perform multiple beam measurements during a symbol period (e.g., at different times within a symbol). For example, a first beam may be active on a first portion of the symbol corresponding to a first time portion for measurement, and a second beam may be active on a different second portion of the symbol corresponding to a second time portion. UE 502 can be configured to switch from the first beam to the second beam before the end of the second time portion associated with the symbol.

[0088] Additionally, UE 502 can be configured to measure the third and fourth beams during the second symbol, and / or at least the fifth beam during the third symbol. Correspondingly, UE 502 can be configured to perform a handover from the third beam to the fourth beam during the second symbol. In all respects, the beam switching rate used by UE 502 for scheduling using split symbols for beam management can be twice the SCS of DL signaling 506. As an example, if DL signaling 506 has an SCS of 120 kHz or approximately 120 kHz, then UE 502 can be configured to use a beam switching rate of 240 kHz or approximately 240 kHz (e.g., approximately twice the signaling SCS) within a single symbol to switch from one beam to another.

[0089] UE 502 can be configured to perform at least one of the following: estimating the RSRP of a first beam (at 510) based on a first measurement or estimating the RSRP of a second beam based on a second measurement. In cases where up to six beams can be measured, individual estimation (at 510) of one or more of the up to six beams can be performed for each measured beam. UE 502 can be configured to perform estimation using R-matrix estimation (at 510). R-matrix estimation can be used with OSBM and / or CIR-based DYB (by way of example and not limitation) to determine the beam used by UE 502 to communicate with base station 504 and to perform beam management for that beam. R-matrix estimation can be performed within a single SSB to support faster performance for UE 502, which has up to six antenna elements in its antenna module.

[0090] UE 502 may be configured to communicate with a network node using a first beam or a second beam based on at least one of a first measurement or a second measurement (or vice versa). That is, in all respects, UE 502 may be configured to provide / transmit communication 512 to base station 504 and / or receive communication from base station 504 using a beam selected based on beam measurement (e.g., at 508) and / or estimation (e.g., at 510).

[0091] Figure 6Figure 600 illustrates an example of beam scheduling for multiple beam measurements within different portions of a symbol in an SSB. For example, Figure 600 shows a scheduling for measuring two beams using a split symbol of an SSB. Beam measurements and estimations in conjunction with Figure 600 may include combinations of... Figure 5 The beam measurement and estimation aspects are described in Figure 500. Figure 600 shows a multi-element antenna module 602 (“antenna module 602”) of UE 603, which has the following five antenna elements, exemplified by: element 1, element 2, element 3, element 4 and element 5.

[0092] As described above, the aspects described herein enable the measurement of two (or more) beams during a single symbol, thereby enabling the measurement of more than three beams using a single SSB, for example. The illustrated aspects show an SSB 604 having a PSS 608, a first PBCH 610, an SSS 612, and a second PBCH 614, each representing a single symbol of the SSB 604. That is, the UE 603 ​​and / or antenna module 602 can be configured to measure a first measurement of a first beam at the UE 603 ​​during a first time portion of the symbol, and a second measurement of a second beam at the UE 603 ​​during a second time portion of the symbol, different from the first time portion. For example, the UE can use the beams during a portion of the SSB symbol to measure the DMRS in the PBCH to obtain the corresponding beam measurement.

[0093] The aspects described herein provide a switching timing 606 between symbols (e.g., between the first PBCH 610 and SSS 612, and between SSS 612 and the second PBCH 614) and during the symbol periods of the first PBCH 610, SSS 612, and the second PBCH 614, which enables two beam measurements within a single symbol. For example, the UE 603 ​​and / or antenna module 602 may be configured to measure the PBCH DMRS, for example, using element 1 of antenna module 602 during a first time portion of the first PBCH 610, to obtain a beam measurement of beam 616. The UE 603 ​​and / or antenna module 602 may also be configured to measure the PBCH DMRS, for example, using element 2 of antenna module 602 during a second time portion of the first PBCH 610, after the switching timing 606 during the symbol period of the first PBCH 610, to obtain a measurement of beam 618. Between the first PBCH 610 and SSS 612, another switching timing 606 allows for switching from beam 618 to beam 620.

[0094] Therefore, UE 603 ​​and / or antenna module 602 can be configured to measure PBCH DMRS, for example, using element 3 of antenna module 602, during the first time portion of SSS 612 to obtain a measurement of beam 620. UE 603 ​​and / or antenna module 602 can also be configured to measure PBCH DMRS, for example, using element 4 of antenna module 602, during the second time portion of SSS 612, after a handover timing 606 during the symbol period for SSS 612, to obtain a beam measurement of beam 622. The handover timing 606 allows a switch from beam 622 to beam 624 between SSS 612 and the second PBCH 614.

[0095] Similarly, UE 603 ​​and / or antenna module 602 may be configured to measure the beam 624 associated with the symbol for the second PBCH 614 during the first time portion of the second PBCH 614 and with respect to element 5 of antenna module 602.

[0096] In one configuration, UE 603 ​​and / or antenna module 602 may be configured to measure one of beams 616, 618, 620, 622, or 624 again during a second time portion of the second PBCH 614 (e.g., based on the timing in the handover timing 606 during the symbol for the second PBCH 614), or to measure different beams (e.g., such as for a six-element antenna module) within a second time portion associated with the symbol for the second PBCH 614.

[0097] In another configuration, UE 603 ​​may be configured to determine / select beam 628 for communication with network nodes associated with SSB 604 (e.g., base stations, gNBs, etc. from which SSB 604 is provided / transmitted). In various respects, beam 628 may be based on measurements performed on the symbols of SSB 604 as described above for at least one of beams 616, 618, 620, 622, and / or 624. R-matrix estimation 626 may be calculated / determined by UE 603.

[0098] R-matrix estimation 626 can be used in OSBM and / or CIR-based DYB (by way of example and not limitation) to determine beam 628 and perform beam management for that beam. R-matrix estimation 626 can be performed within a single SSB (e.g., SSB 604), and therefore, the aspects herein can support this faster performance in devices (e.g., UE 603) with up to six antenna elements in an antenna module (e.g., antenna module 602).

[0099] By way of example, using an OSBM, the RSRP of each beam in the antenna module's beam can be predicted using R-matrix estimation 626. Additionally, aspects provide the ability to generate dynamic beams with optimal RSRP using the calculation of eigenvectors from R-matrix estimation 626. Because all measurements of the R-matrix can be performed in a single SSB, the described aspects provide efficient beam tracking, which results in significant improvements / gains in cases of rotation or fading of the wireless device.

[0100] Figure 7 Figure 700 illustrates examples of beam scheduling using two beams for split symbols of the SSB in various aspects. Figure 700 can be... Figure 5 Figure 500 and / or Figure 6 Another aspect of Figure 600 is shown in Figure 700. Figure 700 shows a multi-element antenna module 702 (“antenna module 702”) of UE 703, which has the following five antenna elements, exemplarily: element 1, element 2, element 3, element 4 and element 5.

[0101] As described herein, aspects enable the measurement of two beams within a single symbol. The illustrated aspect shows an SSB 704 having a PSS 708, a first PBCH 710, an SSS 712, and a second PBCH (not shown for simplicity), each representing a single symbol of the SSB 704. That is, the UE 703 and / or antenna module 702 can be configured to measure a first measurement of the first beam at the UE 703 during a first time portion of the symbol, and a second measurement of the second beam at the UE 703 during a second time portion of the symbol, different from the first time portion.

[0102] The aspects described herein provide a switching timing 706 between symbols (e.g., between the first PBCH 710 and SSS 612) and during symbols (e.g., as shown for the first PBCH 710), which enables two beam measurements within a single symbol. For example, UE 703 and / or antenna module 702 may be configured to measure the beam 716 associated with the symbol for the first PBCH 710 during a first time portion 720 of the first PBCH 710 and with respect to element 1 of antenna module 702. UE 703 and / or antenna module 702 may also be configured to measure the beam 718 associated with the symbol for the first PBCH 710 during a second time portion 722 of the first PBCH 710 and with respect to element 2 of antenna module 702 (e.g., based on the timing in switching timing 706 during the symbol period for the first PBCH 710).

[0103] In various respects, the timing of the switching timing 706 occurring during the symbol period (e.g., as shown for the first PBCH 710) may be midway through or approximately midway through the duration of the symbol. That is, by way of example and not limitation, the symbol splitting measurement herein may be based on the first and second halves of the symbol. In other respects, the timing of the switching timing 706 occurring during the symbol period may occur at any other location within the symbol. That is, the first time portion 720 and the second time portion 722 of the first PBCH 710 may be equal or unequal in duration.

[0104] In some respects, the switching from the first beam to the second beam can be performed at a switching timing prior to the end of the second time portion associated with the symbol. For example, the switching from beam 716 to beam 718 can be performed at a switching timing of 706 prior to the end of the second time portion 722 associated with the symbol used for the first PBCH 710.

[0105] In various configurations, the beam switching rate at the switching timing in switching timing 706 can be at least twice or approximately twice the SCS of the symbol on which beam measurement is performed. As an example, with SSB 704 having an SCS of approximately 120 kHz, the beam switching rate used by UE 703 to switch from beam 716 (for element 1 of antenna module 702) to beam 718 (for element 2 of antenna module 702) can be approximately 240 kHz SCS.

[0106] Figure 8 This is a flowchart 800 of a method for wireless communication in various aspects. The method can be performed by a UE (e.g., UE 104, 502, 603, 703; device 1104). In some aspects, the method may include combining... Figure 5 The communication process described in the document covers various aspects and / or Figure 6 , Figure 7 The described aspects. This method can be used for scheduling using split symbols for beam management, and achieves up to six beam measurements per SSB by splitting the measured symbol into two halves or parts (each part can be used to measure one beam), and achieves increased speed and reduced latency and associated effects by mitigating rotation, fading and / or UE mobility through beam measurements of up to six beams per SSB.

[0107] At 802, the UE receives DL signaling from the network node, which includes symbols located in the first time slot of the DL signaling. As an example, this reception can be achieved by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is shown of UE 502 receiving such DL signaling from a network node (e.g., base station 504).

[0108] UE 502 can be configured to receive DL signaling 506, and base station 504 can be configured to transmit / provide the DL signaling. DL signaling 506 may include symbols. In various aspects, DL signaling may include one or more symbols located in the time slot of DL signaling 506, and in various aspects, may include SSBs (e.g., Figure 6 604 in the middle; Figure 7 The symbols in 704 (e.g., PSS, first PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle), SSS (for example, Figure 6 612 in the middle; Figure 7 712 in the middle) and the second PBCH (e.g., Figure 6 (614 in the middle). In some respects, the first PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle can correspond to the first symbol, SSS (e.g., Figure 6 612 in the middle; Figure 7 712 in the code may correspond to the second symbol, and the second PBCH may correspond to the third symbol. That is, DL signaling 506 may include an SSB (e.g., Figure 6 604 in the middle; Figure 7 (704 in the original text), the SSB includes: the first symbol including PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle), including the second symbol of SSS and PBCH (e.g., Figure 6 612 in the middle; Figure 7 712 in the middle), and the third symbol including PBCH (e.g., Figure 6 (614 in the text). In all respects, symbols received using DL signaling 506 can correspond to SSBs (e.g., Figure 6 604 in the middle; Figure 7 The first, second, or third symbol of (704).

[0109] At 804, the UE measures the first beam at the UE during the first time portion of the symbol (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 The first measurement of 716 in the symbol, and the second beam measured at the UE during a second time portion of the symbol that is different from the first time portion (e.g., Figure 6 618 and 622 in the middle; Figure 7 The second measurement (718) in the text. For example, this measurement can be made by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is illustrated where UE 502 measures such a beam within a symbol in DL signaling from a network node (e.g., base station 504).

[0110] UE 502 can be configured to perform a symbolic action in the first time portion (e.g., Figure 7 During the 720 period, the first beam was measured at UE 502 (at 508). Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 The first measurement of 716 in the symbol, and in the first time part (e.g., Figure 7 The 720 in the middle) is different from the second time part (e.g., Figure 7 During 722) the second beam is measured at UE502 (e.g., Figure 6 618 and 622 in the middle; Figure 7 The second measurement (at 718). In other words, UE 502 can be configured to measure (at 508) two beams using a single symbol. Therefore, UE 502 can be configured to measure in a single SSB (e.g., including three symbols) Figure 6 604 in the middle; Figure 7 During the 704 period, up to six beams (e.g., Figure 6 Up to six measurements can be performed using symbols 616, 618, 620, 622, and 624, which include the PBCH. Up to six beams can be measured (e.g., Figure 6 In aspects 616, 618, 620, 622, and 624, it is possible to perform operations targeting up to six beams (e.g., Figure 6 Individual measurements were taken of each beam in sections 616, 618, 620, 622, and 624. The measured beams (at 508) correspond to the antenna modules / arrays of UE502 (e.g., ...). Figure 6 602 in the middle; Figure 7 The antenna element (702) in the middle.

[0111] In addition, UE 502 can be configured to switch during a symbol (e.g., Figure 6 606 in the middle; Figure 7 706) beam (e.g., split symbol scheduling). For example, the first beam (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 716 in the symbol can be in the first time part (e.g., Figure 7 The first part corresponding to 720 in the middle is active for measurement, and the second beam (e.g., Figure 6618 and 622 in the middle; Figure 7 718 in the symbol can be in the second time part (e.g., Figure 7 The UE 502 can be configured to operate on a different second part corresponding to the symbol (e.g., 722). Figure 7 Before the end of the 722) from the first beam (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 716 in the middle) switch (for example, Figure 6 606 in the middle; Figure 7 (706 in the middle) to the second beam (e.g., Figure 6 618 and 622 in the middle; Figure 7 718 in the middle).

[0112] Additionally, UE 502 can be configured to be in the second symbol (e.g., Figure 6 During the measurement of the third and fourth beams (e.g., in 612) Figure 6 (620, 622), and / or in the third symbol (e.g., Figure 6 During the 614th period, at least the fifth beam (e.g., Figure 6 (624 in the original text). Correspondingly, UE 502 can be configured to perform a handover from the third beam to the fourth beam during the second symbol (e.g., ...). Figure 6 606 in the middle; Figure 7 (referring to 706 in the original text). In all respects, the beam switching rate used by UE 502 for scheduling using split symbols for beam management can be twice the SCS of DL signaling 506. As an example, if DL signaling 506 has an SCS of 120 kHz or approximately 120 kHz, then UE 502 can be configured to use a beam switching rate of 240 kHz or approximately 240 kHz (e.g., approximately twice the signaling SCS) within a single symbol to switch from one beam (e.g., ...). Figure 6 606 in the middle; Figure 7 (706 in the middle) to another beam.

[0113] UE 502 may be configured to perform at least one of the following: estimating (at 510) a first beam based on a first measurement (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 The RSRP of 716 in the middle or the second beam is estimated based on the second measurement (e.g., Figure 6 618 and 622 in the middle; Figure 7 RSRP of 718 (in the example). Measurable up to six beams (e.g., Figure 6In aspects 616, 618, 620, 622, and 624, up to six beams (e.g., for each beam being measured) can be targeted. Figure 6 Individual estimation of one or more beams (at 510) from 616, 618, 620, 622, 624 in the model). UE 502 can be configured to utilize R matrix estimation (e.g., Figure 6 The R-matrix is ​​estimated at 626 (at 510). (e.g., ...) Figure 6 626) can be used in OSBM and / or CIR-based DYB (by way of example and not limitation) to determine the beam (e.g., 628) used by UE 502 to communicate with base station 504 and to perform beam management for that beam. This can be done in a single SSB (e.g., Figure 6 604 in the middle; Figure 7 Perform R matrix estimation within 704 (e.g., Figure 6 (626 in the middle), to support in antenna modules (e.g., Figure 6 602 in the middle; Figure 7 The UE 502 (with up to six antenna elements) has faster performance.

[0114] At point 806, the UE communicates with the network node using a first beam or a second beam based on at least one of a first measurement or a second measurement. As an example, this communication may be at least partially provided by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figure 5 , Figure 6 An example of UE 502 communicating with a network node (e.g., base station 504) is shown.

[0115] UE 502 can be configured to communicate with a network node using a first beam or a second beam based on at least one of a first measurement or a second measurement (or vice versa). That is, in all respects, UE 502 can be configured to use a beam selected based on beam measurement (e.g., at 508) and / or estimation (e.g., at 510). Figure 6 (628) to provide / send communication 512 to base station 504 and / or receive the communication from the base station.

[0116] Figure 9 This is a flowchart 900 of a method for wireless communication in various aspects. The method can be performed by a UE (e.g., UE 104, 502, 603, 703; device 1104). In some aspects, the method may include combining... Figure 5 The communication process described in the document covers various aspects and / or Figure 6 , Figure 7The described aspects. This method can be used for scheduling using split symbols for beam management, and achieves up to six beam measurements per SSB by splitting the measured symbol into two halves or parts (each part can be used to measure one beam), and achieves increased speed and reduced latency and associated effects by mitigating rotation, fading and / or UE mobility through beam measurements of up to six beams per SSB.

[0117] At position 902, the UE receives DL signaling from the network node, which includes symbols located in the first time slot of the DL signaling. As an example, this reception can be achieved by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is shown of UE 502 receiving such DL signaling from a network node (e.g., base station 504).

[0118] UE 502 can be configured to receive DL signaling 506, and base station 504 can be configured to transmit / provide the DL signaling. DL signaling 506 may include symbols. In various aspects, DL signaling may include one or more symbols located in the time slot of DL signaling 506, and in various aspects, may include SSBs (e.g., Figure 6 604 in the middle; Figure 7 The symbols in 704 (e.g., PSS, first PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle), SSS (for example, Figure 6 612 in the middle; Figure 7 712 in the middle) and the second PBCH (e.g., Figure 6 (614 in the middle). In some respects, the first PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle can correspond to the first symbol, SSS (e.g., Figure 6 612 in the middle; Figure 7 712 in the code may correspond to the second symbol, and the second PBCH may correspond to the third symbol. That is, DL signaling 506 may include an SSB (e.g., Figure 6 604 in the middle; Figure 7 (704 in the original text), the SSB includes: the first symbol including PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle), including the second symbol of SSS and PBCH (e.g., Figure 6 612 in the middle; Figure 7 712 in the middle), and the third symbol including PBCH (e.g., Figure 6(614 in the text). In all respects, symbols received using DL signaling 506 can correspond to SSBs (e.g., Figure 6 604 in the middle; Figure 7 The first, second, or third symbol of (704).

[0119] At 904, the UE performs up to six measurements for up to six beams during a single SSB comprising three symbols, including the PBCH. For example, this measurement could be performed by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is illustrated where UE 502 measures such a beam within a symbol in DL signaling from a network node (e.g., base station 504).

[0120] Measurable up to six beams (e.g., Figure 6 In aspects 616, 618, 620, 622, and 624, it is possible to perform operations targeting up to six beams (e.g., Figure 6 Individual measurements were taken of each beam in 616, 618, 620, 622, and 624 (in the original text). The measured beam (at 508) can correspond to the antenna module / array of UE 502 (e.g., ...). Figure 6 602 in the middle; Figure 7 The antenna element (702) in the middle.

[0121] For example, at 906, the UE measures a first measurement of the first beam during the first time portion of the symbol, and measures a second measurement of the second beam during the second time portion of the symbol, which is different from the first time portion. This measurement can be performed by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is illustrated where UE 502 measures such a beam within a symbol in DL signaling from a network node (e.g., base station 504).

[0122] UE 502 can be configured to perform a symbolic action in the first time portion (e.g., Figure 7 During the 720 period, the first beam was measured at UE 502 (at 508). Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 The first measurement of 716 in the symbol, and in the first time part (e.g., Figure 7 The 720 in the middle) is different from the second time part (e.g., Figure 7 During 722) the second beam is measured at UE502 (e.g., Figure 6 618 and 622 in the middle; Figure 7The second measurement (at 718). In other words, UE 502 can be configured to measure (at 508) two beams using a single symbol. Therefore, UE 502 can be configured to measure in a single SSB (e.g., including three symbols) Figure 6 604 in the middle; Figure 7 During the 704 period, up to six beams (e.g., Figure 6 The symbols 616, 618, 620, 622, and 624 in the series perform up to six measurements, and these three symbols include PBCH.

[0123] At 908, the UE switches from the first beam to the second beam before the end of the second time portion associated with the symbol. As an example, this handover can be performed by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example of UE 502 switching between beams to facilitate two-beam measurements within a single symbol is illustrated.

[0124] UE 502 can be configured to switch during symbols (e.g., Figure 6 606 in the middle; Figure 7 706) beam (e.g., split symbol scheduling). For example, the first beam (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 716 in the symbol can be in the first time part (e.g., Figure 7 The first part corresponding to 720 in the middle is active for measurement, and the second beam (e.g., Figure 6 618 and 622 in the middle; Figure 7 718 in the symbol can be in the second time part (e.g., Figure 7 The UE 502 can be configured to operate on a different second part corresponding to the symbol (e.g., 722). Figure 7 Before the end of the 722) from the first beam (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 716 in the middle) switch (for example, Figure 6 606 in the middle; Figure 7 (706 in the middle) to the second beam (e.g., Figure 6 618 and 622 in the middle; Figure 7 718 in the middle).

[0125] At 910, the UE measures the third and fourth beams during the second symbol and at least the fifth beam during the third symbol. For example, this measurement could be performed by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is illustrated where UE 502 measures such a beam within a symbol in DL signaling from a network node (e.g., base station 504). At 912, the UE performs a handover from the third to the fourth beam during the second symbol. As an example, this reception can be achieved by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is given of UE 502 receiving such DL signaling from a network node (e.g., base station 504). As an example, this handover can be performed by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example of UE 502 switching between beams to facilitate two-beam measurements within a single symbol is illustrated.

[0126] UE 502 can be configured to be in the second symbol (e.g., Figure 6 During the measurement of the third and fourth beams (e.g., in 612) Figure 6 (620, 622), and / or in the third symbol (e.g., Figure 6 During the 614th period, at least the fifth beam (e.g., Figure 6 (624 in the original text). Correspondingly, UE 502 can be configured to perform a handover from the third beam to the fourth beam during the second symbol (e.g., ...). Figure 6 606 in the middle; Figure 7 (referring to 706 in the original text). In all respects, the beam switching rate used by UE 502 for scheduling using split symbols for beam management can be twice the SCS of DL signaling 506. As an example, if DL signaling 506 has an SCS of 120 kHz or approximately 120 kHz, then UE 502 can be configured to use a beam switching rate of 240 kHz or approximately 240 kHz (e.g., approximately twice the signaling SCS) within a single symbol to switch from one beam (e.g., ...). Figure 6 606 in the middle; Figure 7 (706 in the middle) to another beam.

[0127] At 914, the UE performs at least one of the following: estimating the RSRP of a first beam based on a first measurement or estimating the RSRP of a second beam based on a second measurement (e.g., this may include estimating the RSRP for measurements of up to six beams). As an example, this estimation may be performed by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figures 5 to 7 An example is illustrated where UE 502 estimates this RSRP based on beam measurements of signaling from a network node (e.g., base station 504).

[0128] UE 502 may be configured to perform at least one of the following: estimating (at 510) a first beam based on a first measurement (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 The RSRP of 716 in the middle or the second beam is estimated based on the second measurement (e.g., Figure 6 618 and 622 in the middle; Figure 7 RSRP of 718 (in the example). Measurable up to six beams (e.g., Figure 6 In aspects 616, 618, 620, 622, and 624, up to six beams (e.g., for each beam being measured) can be targeted. Figure 6 Individual estimation of one or more beams (at 510) from 616, 618, 620, 622, 624 in the model). UE 502 can be configured to utilize R matrix estimation (e.g., Figure 6 The R-matrix is ​​estimated at 626 (at 510). (e.g., ...) Figure 6 626) can be used in OSBM and / or CIR-based DYB (by way of example and not limitation) to determine the beam (e.g., 628) used by UE 502 to communicate with base station 504 and to perform beam management for that beam. This can be done in a single SSB (e.g., Figure 6 604 in the middle; Figure 7 Perform R matrix estimation within 704 (e.g., Figure 6 (626 in the middle), to support in antenna modules (e.g., Figure 6 602 in the middle; Figure 7 The UE 502 (with up to six antenna elements) has faster performance.

[0129] At point 916, the UE communicates with the network node using a first beam or a second beam based on at least one of a first measurement or a second measurement (e.g., based on the estimated RSRP). As an example, this communication may be at least partially provided by... Figure 11 It is performed by one or more of the components 198, transceiver 1122 and / or antenna 1180. Figure 5 , Figure 6 An example of UE 502 communicating with a network node (e.g., base station 504) is shown.

[0130] UE 502 can be configured to communicate with a network node using a first beam or a second beam based on at least one of a first measurement or a second measurement (or vice versa). That is, in all respects, UE 502 can be configured to use a beam selected based on beam measurement (e.g., at 508) and / or estimation (e.g., at 510). Figure 6 (628) to provide / send communication 512 to base station 504 and / or receive the communication from the base station.

[0131] Figure 10 This is a flowchart 1000 of a method for wireless communication in various aspects. The method can be performed by network nodes (e.g., base stations 102, 504; network entities 1102, 1202). In some aspects, the method may include combining... Figure 5 The communication process described in the document covers various aspects and / or Figure 6 , Figure 7 The described aspects. This method can be used for scheduling using split symbols for beam management, and achieves up to six beam measurements per SSB by splitting the measured symbol into two halves or parts (each part can be used to measure one beam), and achieves increased speed and reduced latency and associated effects by mitigating rotation, fading and / or UE mobility through beam measurements of up to six beams per SSB.

[0132] At position 1002, the network node provides or transmits DL signaling to the UE, the DL signaling including symbols located in the first time slot of the DL signaling. As an example, this provision / transmission may be at least partially provided by Figure 12 It is performed by one or more of the components 199, transceiver 1246 and / or antenna 1280. Figures 5 to 7 An example is shown of base station 504 providing or sending such DL signaling to UE (e.g., UE 502).

[0133] UE 502 can be configured to receive DL signaling 506, and base station 504 can be configured to transmit / provide the DL signaling. DL signaling 506 may include symbols. In various aspects, DL signaling may include one or more symbols located in the time slot of DL signaling 506, and in various aspects, may include SSBs (e.g., Figure 6 604 in the middle; Figure 7 The symbols in 704 (e.g., PSS, first PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle), SSS (for example, Figure 6 612 in the middle; Figure 7 712 in the middle) and the second PBCH (e.g., Figure 6 (614 in the middle). In some respects, the first PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle can correspond to the first symbol, SSS (e.g., Figure 6 612 in the middle; Figure 7712 in the code may correspond to the second symbol, and the second PBCH may correspond to the third symbol. That is, DL signaling 506 may include an SSB (e.g., Figure 6 604 in the middle; Figure 7 (704 in the original text), the SSB includes: the first symbol including PBCH (e.g., Figure 6 610 in the middle; Figure 7 710 in the middle), including the second symbol of SSS and PBCH (e.g., Figure 6 612 in the middle; Figure 7 712 in the middle), and the third symbol including PBCH (e.g., Figure 6 (614 in the text). In all respects, symbols received using DL signaling 506 can correspond to SSBs (e.g., Figure 6 604 in the middle; Figure 7 The first, second, or third symbol of (704).

[0134] At point 1004, the network node communicates with the UE using a first beam or a second beam based on at least one of a first measurement or a second measurement, wherein the first measurement is a first beam measured at the UE during a first time portion of the symbol, and wherein the second measurement is a second beam measured at the UE during a second time portion of the symbol, different from the first time portion. As an example, this communication may be at least partially... Figure 12 It is performed by one or more of the components 199, transceiver 1246 and / or antenna 1280. Figures 5 to 7 An example of base station 504 communicating with UE (e.g., UE 502) is shown.

[0135] In some respects, base station 504 can configure UE 502 to be in the first time portion of the symbol (e.g., Figure 7 During the 720 period, the first beam was measured at UE 502 (at 508). Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 The first measurement of 716 in the symbol, and in the first time part (e.g., Figure 7 The 720 in the middle) is different from the second time part (e.g., Figure 7 During 722) the second beam is measured at UE 502 (e.g., Figure 6 618 and 622 in the middle; Figure 7 The second measurement (at 718). In other words, the base station can configure UE 502 to measure (at 508) two beams using a single symbol. Therefore, UE 502 can be configured to measure (at 508) two beams using a single SSB comprising three symbols (e.g., Figure 6 604 in the middle; Figure 7During the 704 period, up to six beams (e.g., Figure 6 Up to six measurements can be performed using symbols 616, 618, 620, 622, and 624, which include the PBCH. Up to six beams can be measured (e.g., Figure 6 In aspects 616, 618, 620, 622, and 624, it is possible to perform operations targeting up to six beams (e.g., Figure 6 Individual measurements were taken of each beam in 616, 618, 620, 622, and 624 (in the original text). The measured beam (at 508) can correspond to the antenna module / array of UE 502 (e.g., ...). Figure 6 602 in the middle; Figure 7 The antenna element (702) in the middle.

[0136] In addition, base station 504 can configure UE 502 to switch during a symbol (e.g., Figure 6 606 in the middle; Figure 7 706) beam (e.g., split symbol scheduling). For example, the first beam (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 716 in the symbol can be in the first time part (e.g., Figure 7 The first part corresponding to 720 in the middle is active for measurement, and the second beam (e.g., Figure 6 618 and 622 in the middle; Figure 7 718 in the symbol can be in the second time part (e.g., Figure 7 The UE 502 may be configured by base station 504 to operate on a different second portion corresponding to the symbol (e.g., 722). Figure 7 Before the end of the 722) from the first beam (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 716 in the middle) switch (for example, Figure 6 606 in the middle; Figure 7 (706 in the middle) to the second beam (e.g., Figure 6 618 and 622 in the middle; Figure 7 718 in the middle).

[0137] Additionally, UE 502 may be configured by base station 504 to measure the third and fourth beams during the second symbol period, and / or to measure at least the fifth beam during the third symbol period. Correspondingly, base station 504 may configure UE 502 to perform a handover from the third beam to the fourth beam during the second symbol period (e.g., Figure 6 606 in the middle; Figure 7(referring to 706 in the original text). In various respects, the beam switching rate used by UE 502 for scheduling using split symbols for beam management can, for example, be configured by base station 504 to be twice the SCS of DL signaling 506. As an example, if DL signaling 506 has an SCS of 120 kHz or approximately 120 kHz, then UE 502 can be configured to use a beam switching rate of 240 kHz or approximately 240 kHz (e.g., approximately twice the signaling SCS) within a single symbol to switch from one beam (e.g., ...). Figure 6 606 in the middle; Figure 7 (706 in the middle) to another beam.

[0138] Base station 504 may configure UE 502 to perform at least one of the following: estimating (at 510) a first beam based on a first measurement (e.g., Figure 6 The numbers 616, 620, and 624 are mentioned. Figure 7 The RSRP of 716 in the middle or the second beam is estimated based on the second measurement (e.g., Figure 6 618 and 622 in the middle; Figure 7 RSRP of 718 (in the example). Measurable up to six beams (e.g., Figure 6 In aspects 616, 618, 620, 622, and 624, up to six beams (e.g., for each beam being measured) can be targeted. Figure 6 Individual estimation of one or more beams from 616, 618, 620, 622, 624 (at 510). UE 502 can be configured by base station 504 to utilize R matrix estimation (e.g., Figure 6 The R-matrix is ​​estimated at 626 (at 510). (e.g., ...) Figure 6 626) can be used in OSBM and / or CIR-based DYB (by way of example and not limitation) to determine the beam (e.g., 628) used by UE 502 to communicate with base station 504 and to perform beam management for that beam. This can be done in a single SSB (e.g., Figure 6 604 in the middle; Figure 7 Perform R matrix estimation within 704 (e.g., Figure 6 (626 in the middle), to support in antenna modules (e.g., Figure 6 602 in the middle; Figure 7 The UE 502 (with up to six antenna elements) has faster performance.

[0139] Base station 504 can configure UE 502 to communicate with network nodes using a first beam or a second beam based on at least one of a first measurement or a second measurement (or vice versa). That is, in all respects, UE 502 can be configured by base station 504 to use a beam selected based on beam measurement (e.g., at 508) and / or estimation (e.g., at 510).

[0144] In wireless communication networks, beam management can improve communication between network nodes (e.g., base stations, gNBs, etc.) and UEs. In some examples, the UE can measure a single beam within each symbol, for example, using the PBCH DMRS received in the symbol. If the PBCH is transmitted in two of the three symbols in an SSB, and there is an SSS (e.g., PBCH, SSS, PBCH) or its burst set between the two PBCHs, the UE can measure three beams on the three symbols of the SSB. In some aspects, OSBMs and CIR-based DYBs can manage beams using the estimation of the channel-dependent R matrix. However, such solutions can be inefficient in terms of latency and / or accuracy. That is, the single-beam-per-symbol approach utilizes multiple SSBs to measure the beam of a five-element antenna module, and using two SSBs to estimate the R matrix of such an antenna module can have estimates that may be affected by channel changes associated with fading and / or UE mobility over the length of time during which multiple SSBs are received. For example, the delay measured on the second SSB can be susceptible to fading channels or UE mobility, and the correlation of the R matrix may be estimated under degraded conditions. Degraded estimation can affect beam tracking performance.

[0145] The aspects of scheduling for beam management utilizing split symbols described in this paper achieve up to six beam measurements per SSB by splitting the measured symbol into two halves or parts (each part can be used to measure a different beam). Additionally, since beam measurement mitigates rotation, fading, and / or UE mobility by measuring up to six beams per SSB, speed is increased and latency and associated effects are reduced. Therefore, improvements in the utilization of OSBM and DYB specific implementations are achieved by estimating the RSRP of all static beams to generate a DYB with improved accuracy within a single SSB.
