Description

Technical Field

[0001] In general, this disclosure relates to communication systems, and more specifically, to wireless communication methods that include reporting of simplified synchronization signal blocks (SSBs) to achieve beam management. Background Technology

[0002] 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 employ multiple access technologies that enable 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.

[0003] 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, country, regional, and even global levels. An exemplary telecommunications standard is 5G New Radio (NR). 5G NR is part of the continuous evolution of mobile broadband, promulgated 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. There is a need for further improvements to 5G NR technology. These improvements can also be applied to other multiple access technologies and telecommunications standards that employ them. Summary of the Invention

[0004] The following is a brief overview of one or more aspects to provide a basic understanding of these aspects. This overview is not a comprehensive summary of all anticipated aspects, nor is it intended to identify key or important factors of all aspects, nor to describe the scope of any or all aspects. The sole purpose of this overview is to present some concepts of one or more aspects in a simplified form as an introduction to the more detailed description that follows.

[0005] In one aspect of this disclosure, a method, computer-readable medium, and apparatus are provided. A user equipment (UE) can receive at least one simplified SSB from a base station, each of the at least one simplified SSB being received in one symbol of at least one symbol, and each of the at least one simplified SSB including a synchronization signal of the same kind in each of the at least one symbol; measure at least one parameter associated with the received at least one simplified SSB; and send a measurement report to the base station indicating the at least one parameter measured associated with the received at least one simplified SSB. The UE can receive a configuration indicating a simplified SSB resource set. The configuration can also indicate UL resources for sending the measurement report to the base station. The configuration can be received via a Radio Resource Control (RRC) message. When the simplified SSB is semi-persistent or aperiodic, the UE can also receive activation / deactivation or triggering of the configured simplified SSB resource set via a Media Access Control (MAC) Control Element (MAC-CE) or Downlink Control Information (DCI).

[0006] For the purposes of the foregoing and related objectives, the one or more aspects include the features fully described below and specifically pointed out in the claims. Certain illustrative features of the one or more aspects are set forth in detail in the following description and drawings. However, these features indicate only a few of the various ways in which the principles of the aspects can be employed, and this description is intended to include all such aspects and their equivalents.

[0021] The specific embodiments described below with reference to the accompanying drawings are intended as descriptions of various configurations and are not intended to represent the only configuration in which the concepts described herein can be practiced. Specific details are included in this specific embodiment to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that 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.

[0022] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and methods. These apparatuses and methods will be described in the following detailed embodiments and illustrated in the accompanying drawings through various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements can 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 overall system.

[0023] For example, an element, any part of an element, or any combination of elements can be implemented as a "processing system" including one or more processors. 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, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in a processing system can execute software. Software should be interpreted broadly as meaning instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable programs, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description languages, or other terms.

[0024] Therefore, in one or more exemplary embodiments, the described functionality can be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality can be stored or encoded as one or more instructions or code on a computer-readable medium. A computer-readable medium includes a computer storage medium. The storage medium can be any available medium accessible by a computer. For example, and not as a limitation, such a computer-readable medium can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of computer-readable media of the types described above, or any other medium that can be used to store computer-executable code having computer-accessible instructions or data structures.

[0025] While aspects and implementations are described herein by way of example, those skilled in the art will understand that other implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, implementations and / or uses 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 devices, retail / purchasing devices, medical devices, devices with artificial intelligence (AI) capabilities, etc.). While some examples may or may not be specific to a particular use case or application, a wide variety of applications of the described innovations are possible. The range of implementations can extend 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 aspects of the described innovations. 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 require 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 aim is to implement the innovations described herein in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or decomposed components, end-user equipment, etc., with different sizes, shapes, and compositions.

[0026] Figure 1 This diagram illustrates an example of a wireless communication system and access network 100. The wireless communication system (also known as a wireless wide area network (WWAN)) includes base station 102, UE 104, evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells include base stations. Small cells include femtocells, picocells, and microcells.

[0027] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can interface with core network 190 via a second backhaul link 184. Among other functions, base station 102 can also perform one or more of the following functions: transmission of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), user and equipment tracking, RAN information management (RIM), paging, location, and warning message delivery. Base station 102 can communicate directly or indirectly with each other (e.g., via EPC 160 or core network 190) via third backhaul link 134 (e.g., X2 interface). First backhaul link 132, second backhaul link 184 and third backhaul link 134 can be wired or wireless.

[0028] Base station 102 can wirelessly communicate with UE 104. Each base station 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. The heterogeneous network may also include a Home Evolution Node B (eNB) (HeNB) that can provide services to restricted groups referred to as Closed Subscriber Groups (CSGs). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also known as forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. Base station 102 / UE 104 can use a total of up to [amount missing] for transmission in each direction. Yx MHz ( x In carrier aggregation (of component carriers), each carrier is allocated up to [amount missing]. YA spectrum with a bandwidth of MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.). Carriers may be adjacent to each other or not. Carrier allocation may be asymmetrical for DL ​​and UL (e.g., more or fewer carriers may be allocated to DL than to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carrier may be referred to as the secondary cell (SCell).

[0029] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL 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 achieved through various wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0030] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154, such as 5 GHz unlicensed spectrum. When communicating in unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.

[0031] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) as the Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can improve access network coverage and / or increase access network capacity.

[0032] The electromagnetic spectrum is typically subdivided into categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is generally (interchangeably) referred to as the “sub-6 GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is generally (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30 GHz – 300 GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0033] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have identified the operating bands used for these IF bands as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling into FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 into the IF band. Additionally, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been identified as the frequency range designations FR2-2 (52.6 GHz – 71 GHz), FR4 (71 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0034] Taking the foregoing into account, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz," etc., as used herein, can broadly refer to frequencies that are less than 6 GHz, within FR1, or can include intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that the terms "millimeter wave," etc., as used herein, can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR2-2, FR4 and / or FR5, or within the EHF band.

[0035] Base station 102 (whether a small cell 102' or a large cell (e.g., a macro base station)) may include and / or be referred to as an eNB, g-node B (gNB), or another type of base station. Some base stations (e.g., gNB 180) may operate in conventional sub-6 GHz spectrum, millimeter wave frequencies, and / or near-millimeter wave frequencies to communicate with UE 104. When gNB 180 operates in millimeter wave or near-millimeter wave frequencies, gNB 180 may be referred to as a millimeter wave base station. Millimeter wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short range. Both base station 180 and UE 104 may include multiple antennas (e.g., antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming.

[0036] Base station 180 may transmit beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamformed signals from base station 180 in one or more receive directions 182''. UE 104 may also transmit beamformed signals to base station 180 in one or more transmit directions. Base station 180 may receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 may perform beam training to determine the optimal receive and transmit directions for each of base station 180 / UE 104. The transmit and receive directions of base station 180 may be the same or different. The transmit and receive directions of UE 104 may be the same or different.

[0037] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 can communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. The BM-SC 170 provides functionality for MBMS user service provisioning and delivery. It can serve as an entry point for content provider MBMS transmissions, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 distributes MBMS services to base station 102 within a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and is responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0038] Core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and core network 190. Typically, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP service 197. IP service 197 may include the Internet, intranet, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming (PSS) service, and / or other IP services.

[0039] Base stations may include and / or be referred to as gNB, Node B, eNB, access point, base transceiver, wireless base station, wireless transceiver, transceiver functional unit, basic service set (BSS), extended service set (ESS), transmit / receive point (TRP), or some other suitable term. Base station 102 provides UE 104 with access to EPC 160 or core network 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptop devices, personal digital assistants (PDAs), satellite radio devices, global positioning systems, 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, implantable devices, sensors / actuators, displays, or any other similar functional devices. Some UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, ovens, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, user station, mobile unit, user unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile user station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or any other suitable term. In some scenarios, the term UE may also apply to one or more accompanying devices in a device constellation arrangement. One or more of these devices may jointly access the network and / or individually access the network.

[0040] Refer again Figure 1In some aspects, UE 104 may include a simplified SSB component 198 configured to: receive at least one simplified SSB from a base station, each of the at least one simplified SSB being received in one of at least one symbols, and each of the at least one simplified SSB including a synchronization signal of the same kind in each of the at least one symbols; measure at least one parameter associated with the received at least one simplified SSB; and send a measurement report to the base station indicating the measured at least one parameter associated with the received at least one simplified SSB. In some aspects, base station 180 may include a simplified SSB component 199 configured to: send at least one simplified SSB to the UE, each of the at least one simplified SSB being sent in one of at least one symbols, and each of the at least one simplified SSB including a synchronization signal of the same kind in each of the at least one symbols; and receive from the UE a measurement report indicating the measurement of at least one parameter associated with the sent at least one simplified SSB. Although the following description may focus on 5G NR, the concepts described herein can be applied to other similar areas, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0041] Figure 2A Figure 200 shows an example of the first subframe within a 5G NR frame structure. Figure 2B Figure 230 shows an example of a DL channel within a 5G NR subframe. Figure 2C Figure 250 shows 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 either Frequency Division Duplex (FDD) or Time Division Duplex (TDD). In FDD, a specific set of subcarriers (carrier system bandwidth) is used, and subframes within this set are dedicated to either DL or UL. In TDD, a specific set of subcarriers (carrier system bandwidth) is used, and subframes within this set are dedicated to both DL and UL. Figure 2A , 2CIn the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (mostly DL), where D is DL, U is UL, and F is flexible for use between DL / UL, and subframe 3 is configured with slot format 1 (all 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 all DL and all UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The UE is configured with a slot format via a 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 above description also applies to 5G NR frame structures as TDD.

[0042] Figures 2A-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 mini-time slots, which may include 7, 4, or 2 symbols. Depending on whether the cyclic prefix (CP) is normal or extended, each time slot may include 14 or 12 symbols. 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 can be CP Orthogonal Frequency Division Multiplexing (PFDM) (CP-OFDM) symbols. Symbols on the UL can be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and the digital scheme (numerology). The digital scheme defines the subcarrier spacing (SCS) and, in effect, the symbol length / duration, which is equal to 1 / SCS.

[0043]

[0044] For a normal CP (14 symbols / slot), different digital schemes µ0 through 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For an extended CP, digital scheme 2 allows 4 slots per subframe. Accordingly, for both the normal CP and digital scheme µ, there are 14 symbols / slot and 2 slots per subframe. µ One time slot / subframe. The subcarrier spacing can be equal to 2. µ 15 kHz, whereµ These are digital schemes 0 through 4. Therefore, digital scheme µ=0 has a subcarrier spacing of 15 kHz, and digital scheme µ=4 has a subcarrier spacing of 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figures 2A-2D Examples are provided for a normal CP with 14 symbols per slot and a digital scheme µ=2 with 4 slots per subframe. The 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 different bandwidth portions (BWPs) of frequency division multiplexing (see [link to relevant documentation]). Figure 2B Each BWP can have a specific digital scheme and CP (normal or extended).

[0045] 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.

[0046] like Figure 2A As shown, some REs carry reference (pilot) signals (RS) for the UE. RSs may include demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are also possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. RSs may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0047] Figure 2BExamples of various DL channels within a subframe of a frame are shown. 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 symbols of an 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 a PDCCH search space (e.g., a common search space, a UE-specific search space) during PDCCH monitoring on a CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can be located at higher and / or lower frequencies across the channel bandwidth. The Primary Synchronization Signal (PSS) can be 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 identity. The Secondary Synchronization Signal (SSS) can be within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the Physical Layer Cell Identity Group Number and radio frame timing. Based on the Physical Layer Identity and Physical Layer Cell Identity Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can logically be grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides multiple RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted via the PBCH, such as the System Information Block (SIB) and paging messages.

[0048] like Figure 2C As shown, some REs carry DM-RS for channel estimation at the base station (indicated as R for a specific configuration, but other DM-RS configurations are also possible). 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 DMRS can be transmitted in the first one or two symbols of the PUSCH. The PUCCH DMRS can be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and on the specific PUCCH format used. 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 these combs. The SRS can be used by the base station for channel quality estimation to implement frequency-dependent scheduling on the UL.

[0049] Figure 2DExamples of various UL channels within a subframe of a frame are shown. The PUCCH can be positioned as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding 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 also be used to carry buffer status reports (BSR), power headroom reports (PHR), and / or UCIs.

[0050] Figure 3 This is a block diagram illustrating communication between base station 310 and UE 350 in the access network. In the DL, IP packets from EPC 160 can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Serving 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 functions 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 reports; PDCP layer functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with transmission 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 functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs to transport blocks (TBs), demultiplexing of MAC SDUs and TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel prioritization.

[0051] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection on the transport channel, forward error correction (FEC) encoding / 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-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The encoded 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 streams are spatially precoded to produce multiple spatial streams. The channel estimate from the channel estimator 374 can be used to determine the coding and modulation scheme and for spatial processing. The channel estimate can be derived from the reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can use the corresponding spatial stream to modulate a radio frequency (RF) carrier for transmission.

[0052] At UE 350, each receiver 354 RX receives signals through its corresponding antenna 352. Each receiver 354 RX recovers the information modulated onto the RF carrier and provides this information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functions 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, they can be combined by the RX processor 356 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 and reference signals on each subcarrier are recovered and demodulated by determining the most probable signal constellation point transmitted by base station 310. These soft decisions can be based on channel estimates calculated by channel estimator 358. The soft-decision decoding and deinterleaving are then performed 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 functions.

[0053] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The 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 from the EPC 160. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0054] Similar to the functions described in the DL transmission performed in conjunction with base station 310, controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with upper-layer PDU transmission, 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 functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs on TBs, demultiplexing of MAC SDUs and TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel prioritization.

[0055] The channel estimate derived by the channel estimator 358 from the reference signal or feedback transmitted by the base station 310 can be used by the TX processor 368 to select an appropriate coding 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.

[0056] UL transmissions are 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 the RX processor 370.

[0057] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The 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 between transport and logical channels to recover IP packets from the UE 350. IP packets from the controller / processor 375 can be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0058] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform combination. Figure 1 The various aspects of 198. At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform combined Figure 1 199 in all aspects.

[0059] Reduced Capability (RedCap) devices (e.g., low-level UEs, new radio (NR) lightweight UEs, etc.) can operate with one or more of the following: reduced transmit power, a reduced number of transmit and / or receive antennas, reduced transmit / receive bandwidth, or reduced computational complexity. For example, RedCap devices can be smart wearables, industrial sensors, video surveillance equipment, etc. Compared to high-end enhanced mobile broadband (eMBB) or ultra-reliable low-latency communication (URLLC) devices, RedCap devices generally have lower device cost and complexity, smaller device size (such as device designs with compact form factors), or specific deployment scenarios, including systems supporting all frequency range 1 (FR1) and frequency range 2 (FR2) bands of frequency division duplex (FDD) and time division duplex (TDD). For example, RedCap devices can include wireless sensors configured to monitor and communicate with a central server using uplink communication, video surveillance cameras heavily reliant on uplink transmissions with low latency and high reliability, or wearable devices with limited size and battery power.

[0060] In some aspects, signaling overhead can be reduced to accommodate RedCap devices. Reduced signaling overhead can lower the complexity of RedCap devices because they can decode less data and control. Therefore, RedCap devices can have reduced capabilities.

[0061] A Synchronization Signal Block (SSB) contains reference signals used for time-frequency synchronization for initial access and beam management. That is, an SSB is a normally open signal that may include a PSS and an SSS, as well as the PBCH. Initially, the SSB can be used for time-frequency synchronization, and after initial configuration, it can be used for beam management. However, the SSB incurs signaling overhead. After time-frequency synchronization during the initial access procedure, a simplified SSB can be introduced to reduce SSB bandwidth and support beam management and / or time-frequency tracking functions for RedCap devices. A simplified SSB can be a PSS or SSS in a single symbol, associated with a transmit beam direction from the base station. In one aspect, gaps can be allocated on either side of the simplified SSB. Each simplified SSB can be transmitted within a simplified SSB resource in a single symbol, and the simplified SSB resource set can be configured by the base station for transmitting a set of simplified SSBs to the UE. Each SSB in a set of simplified SSBs within the same simplified SSB resource set can have the same kind of synchronization signal, such as one of a PSS or an SSS.

[0062] For example, a simplified SSB can be used for beam management signals instead of initial access. Accordingly, RedCap devices can reduce power consumption and save computational resources by reducing their operating bandwidth (e.g., compared to the operating bandwidth associated with monitoring a regular SSB). The base station can configure the same type of reference signal in the simplified SSB, and the UE can measure the reference signal and send a report back to the base station. That is, the base station can configure a simplified SSB to include a synchronization signal containing either a PSS or an SSS.

[0063] In some aspects, the UE can receive a simplified SSB for beam adaptation, and the UE can generate a report and send it to the base station to achieve this beam adaptation process. The UE can generate and send reports based on the simplified SSB in a manner similar to other reference signals (such as CSI-RS and SSB in 5G NR). New reporting and / or resource structures can enable beam management based on the simplified SSB. That is, in order to perform beam management based on the simplified SSB, the UE can measure and generate a report on the simplified SSB.

[0064] For example, a base station can send three types of reference signals to a UE, including SSB, CSI-RS, and CSI interference measurement (CSI-IM). These reference signals are used for measurement and reported back to the base station by the UE. That is, the base station can send reference signals including SSB, CSI-RS, and CSI-IM to the UE, and the UE can measure the reference signals from the base station and send a corresponding report instructing the measurement to the base station. For example, SSB can be used during initial access to obtain the cell ID, master information block (MIB), and for time-frequency synchronization purposes. SSB can also be used for beamforming decisions, such as being sent within a single SSB burst or using multiple SSBs (e.g., up to 64 SSBs for millimeter-wave (mmW) frequencies), where each SSB uses a different transmit beam. As another example, CSI-RS can be sent by the base station to the UE on demand to measure the reference signal received power (RSRP) or signal-to-interference-plus-noise ratio (SINR) for beamforming purposes. As yet another example, the base station can instruct the UE to perform interference measurements by sending a CSI-IM signal. The UE can measure interference based on the CSI-IM received from the base station and send a report to the base station.

[0065] The base station and UE can be configured to transmit CSI reports for any of the three reference signals (e.g., SSB, CSI-RS, and CSI-IM). The configuration for the CSI report can include at least one of the following: a set of parameters to be reported to the base station, downlink resources or resource sets to be used for measurement to infer the parameters, and / or the report format. For example, the set of parameters to be reported to the base station can include CSI-related parameters (including Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), CSI-RS Resource Indicator (CRI), SS / PBCH Block Resource Indicator (SSBRI), Layer Indicator (LI), Rank Indicator (RI)) and / or L1 RSRP-related parameters (including L1 RSRP (L1-RSRP) and / or L1 SINR (L1-SINR)).

[0066] For example, downlink resources or resource sets used for measurement (which can be used to infer reported parameters) may also include non-zero power (NZP) CSI resource sets (NZP-CSI-RS) and / or SSB resource sets (SSB-RS) for beam management, and CSI-IM resource sets (CSI-IM-RS) for interference management. For example, the configuration may instruct the UE to generate a CSI report based on four beams used for aperiodic CSI-RS. In yet another example, the format of the actual report may include type (e.g., periodic, aperiodic, semi-persistent), frequency (i.e., how frequently the synchronization signal repeats), and / or the physical channel to be used to send the report to the base station, etc. An example of a CSI report structure can be represented by Table I provided below.

[0067]

[0068] Table I. Example of CSI Report Structure

[0069] For example, the possible set of reported parameters may include 'None', 'CSI-RS Resource Index (CRI)-RI-PMI-CQI (CRI-RI-PMI-CQI)', 'CRI-RI-i1', 'CRI-RI-i1-CQI', 'CRI-RI-CQI', 'CRI-RSRP', 'CRI-SINR', 'SSB-Index-RSRP', 'SSB-Index-SINR', and 'CRI-RI-LI-PMI-CQI'. Regarding reporting parameters, periodic CSI reports can be sent via periodically allocated PUCCH. Semi-persistent CSI reports can be sent via either periodically allocated PUCCH or semi-persistently allocated PUSCH. Non-periodic reports can be sent on a scheduled PUSCH triggered by the base station using DCI or MAC-CE.

[0070] Configurations can be provided to establish a reporting structure with a reduced SSB resource set. That is, aspects of this disclosure can define a reporting structure for reporting reduced SSB resource sets to base stations for beam management purposes.

[0071] In some aspects, resources for transmitting reports and reported parameters associated with the reports can be provided to enable measurements utilizing a simplified SSB resource set. In some aspects, these reported parameters can be calculated from symbols connected to specific transmit and receive beams in the simplified SSB. In some aspects, the relationship between the type of report (i.e., periodic, aperiodic, semi-persistent) and the type of simplified SSB can be defined.

[0072] In some aspects, the base station can configure the UE to send reports with physical layer (e.g., L1) measurements performed on a simplified SSB. That is, the base station can configure the UE to perform L1 measurements on the simplified SSB and send an L1 measurement report to the base station. For reporting purposes, the base station can notify the UE of the parameters or set of parameters to be reported, the set of simplified SSB resources used for performing the measurements with appropriate configuration, and the uplink resources used for sending the report including the measurements.

[0073] In some aspects, the parameters or set of parameters to be reported may include newly defined L1 measurements using a simplified SSB, including but not limited to RSRP, Reference Signal Received Quality (RSRP), Signal-to-Noise Ratio (SNR), and / or SINR. That is, the base station may instruct the UE to generate one or a set of L1 measurements using a simplified SSB, including RSRP, RSRQ, SNR, and / or SINR. For example, the parameters used for this configuration may be referred to as 'leanssb-Index-RSRP', 'leanssb-Index-RSRQ', 'leanssb-Index-SNR', and / or 'leanssb-Index-SINR', respectively, for RSRP, RSRQ, SNR, and / or SINR. The base station may indicate in the reporting configuration which parameter or set of parameters to report. That is, the base station can use the reporting configuration to instruct the UE to report a parameter or set of parameters. The base station can use the received reports to perform beam management in the downlink. Base stations can improve link performance by changing their transmit beam, for example, by selecting a narrower or wider beam or by switching beams, and / or by changing downlink transmission parameters (such as modulation and coding rates).

[0074] In one aspect, a simplified SSB resource set can be associated with multiple beams, one or a group of L1 measurements can be generated on more than one beam associated with the simplified SSB resource set, and the report can include a beam index associated with the measurement of each beam (e.g., RSRP, SINR, etc.).

[0075] Figure 4 An example of a simplified SSB configuration 400 for wireless communication is shown. A simplified SSB may include at least one symbol, and each of these symbols may include a synchronization signal. For example, a base station may configure a first simplified SSB symbol 402 associated with a first beam (i.e., beam 0), a second simplified SSB symbol 404 associated with a second beam (i.e., beam 1), and a third simplified SSB symbol 406 associated with a third beam (i.e., beam 2).

[0076] In some aspects, each simplified SSB in the simplified SSB resource set can be bound to at least one base station transmit beam. In one aspect, each simplified SSB can correspond to one base station transmit beam. That is, the simplified SSB resource set can include one or more simplified SSBs or one or more simplified SSB symbols. Multiple simplified SSB symbols can be configured per transmit beam to enable the UE to perform certain functions (e.g., Rx beam scanning or obtaining improved frequency synchronization, etc.). When multiple simplified SSB symbols are configured for multiple transmit beams, synchronization signals of the same kind can be beamformed in different ways for the same sequence according to each of the multiple transmit beams. Furthermore, the base station can select different synchronization signal sequence roots for each serving cell, and synchronization signals of the same kind can have different sequences depending on the serving cell that can carry the simplified SSB resource set. For example, the base station can configure configuration A for simplified SSB resource set 410, including simplified SSB resource 0 412, simplified SSB resource 1 414, and simplified SSB resource 2 416. Reduced SSB resource 0 412 may include a first reduced SSB symbol 402 starting at time slot position 0. Reduced SSB resource 1 414 may include two second reduced SSB symbols 404 starting at time slot position 2. Reduced SSB resource 2 416 may include two third reduced SSB symbols 406 starting at time slot position 5. Accordingly, the configuration 430 of the simplified SSB resource set from the base station to the UE may include parameters common to all resources (e.g., aperiodic type and b0 BWP), and also includes resource configurations including 'resource ID: 0, #symbols / beam0: 1, location: [0]' indicating simplified SSB resource 0 412, 'resource ID: 1, #symbols / beam0: 1, location: [0]' indicating simplified SSB resource 1 414, 'resource ID: 1, #symbols / beam1: 2, location: [2]' indicating simplified SSB resource 1 416, and 'resource ID: 2, #symbols / beam2: 2, location: [5]' indicating simplified SSB resource 2 416.

[0077] In another aspect, a simplified SSB resource may include simplified SSB symbols bound to multiple base station transmit beams. Each Tx beam may have multiple symbols to enable the UE to perform certain functions (e.g., Rx beam scanning or obtaining improved frequency synchronization, etc.). For example, a base station may configure configuration B 420 for a set of simplified SSB resources, including simplified SSB resource 0 422, which includes a first simplified SSB symbol 402 starting at time slot position 0, two second simplified SSB symbols 404 starting at time slot position 2, and two third simplified SSB symbols 406 starting at time slot position 5. Accordingly, the configuration 440 for the simplified SSB resource set from the base station to the UE may include common parameters of the resources (e.g., aperiodic type, b0 BWP, and resource ID 0), and also includes resource configurations including '#symbols / beam0: 1, location: [0]' indicating a first simplified SSB symbol 402 starting at slot 0, '#symbols / beam1: 2location: [2]' indicating two second simplified SSB symbols 404 starting at slot 2, and '#symbols / beam2: 2, location: [5]' indicating two third simplified SSB symbols 406 starting at slot 5.

[0078] In some aspects, the base station can notify the UE of a simplified SSB configuration, which includes at least one parameter (including resource ID, type, bandwidth portion (BWP), serving cell ID) and other parameters. A resource ID can be configured for each simplified SSB resource, and it has a unique resource ID used to indicate each simplified SSB resource.

[0079] Simplified SSB configuration can indicate the type of simplified SSB resource, such as periodic, aperiodic, or semi-persistent. Semi-persistent simplified SSB resources can refer to periodic simplified SSB resources that can be activated or deactivated via lower-layer (e.g., L1 or MAC layer) signaling. If the resource type is periodic, the base station can configure the resource via RRC messages. If the resource type is aperiodic, the base station can use DCI signaling and additionally use MAC-CE to trigger the resource. If the resource type is semi-persistent, the base station can configure the resource via RRC signaling and use MAC-CE or DCI signaling to activate or deactivate the resource.

[0080] A simplified SSB configuration can indicate in which BWP (Browser Tool Package) the resources will be presented or provided. The simplified SSB configuration can indicate the serving cell ID that can send simplified SSB resources. The simplified SSB configuration can include zero or more cell IDs specified to the UE to indicate which cells are sending the resources. If the configuration does not include serving cell IDs, the UE can implicitly assume that the resources are on the same serving cell as the received simplified SSB configuration.

[0081] Simplified SSB configuration may include repetition, which indicates whether there are repeated symbols for resources for the UE to perform, for example, Rx beam scanning or thinning. Simplified SSB configuration may also include other parameters, such as the location of the at least one resource in the simplified SSB resource set, the symbol and slot offset of the simplified SSB resource set, the period of the at least one resource in the simplified SSB resource set, or the time density and time repetition value of the aperiodic simplified SSB resource set.

[0082] In some aspects, L1 reports (e.g., L1-RSRP, L1-RSRQ, L1-SINR, or L1-SNR) sent by the UE may include measurements for each resource in a resource set configured by the base station. L1 reports may include a resource ID or index and a corresponding value for the reported parameter with appropriate units. When similar parameters (e.g., L1-SINR) are reported for multiple resources, the values ​​may be specified independently or relative to each other.

[0083] In one aspect, each value can be reported independently. That is, the absolute or quantified value of each value can be reported. For example, as shown in Table II-A, an absolute value in dB can be reported for each resource index of a reduced SSB resource set. In another aspect, each value can be reported relative to values ​​on other resources. For example, as shown in Table II-B, an absolute value can be reported for resource index 0, and relative values ​​relative to resource index 0 can be reported for other resource indices. When each reduced SSB resource set provides multiple beams, values ​​can be reported independently within the same resource or relative to other values. For example, as shown in Table II-C, an absolute value in dB can be reported for each resource index of a reduced SSB resource set associated with different beams. For another example, as shown in Table II-D, an absolute value can be reported for the first beam of each resource index, and relative values ​​relative to the first beam of the corresponding resource index can be reported for other beams.

[0084]

[0085] In some aspects, L1 report values ​​reported by the UE can be quantized and truncated to a maximum number of bits to reduce overhead. That is, the UE can quantize or truncate at least a portion of the values ​​in the L1 report to reduce signaling overhead. For example, the UE can send the maximum value of L1-SINR or L1-RSRP in the report and omit other values ​​to further reduce signaling overhead.

[0086] Table III shows the report types that can be associated with each resource type.

[0087]

Simplified SSBs can be received periodically, and semi-persistent L1 reports for periodic simplified SSBs can be activated for transmission in the PUCCH via MAC-CE or in the PUSCH via DCI. Simplified SSBs can be received semi-persistently, and semi-persistent L1 reports for semi-persistent simplified SSBs can be activated for transmission in the PUCCH via MAC-CE or in the PUSCH via DCI. Simplified SSBs can be received periodically, and aperiodic L1 reports for periodic simplified SSBs can be triggered for transmission in the PUSCH via at least one of DCI or MAC-CE. Simplified SSBs can be received semi-persistently, and aperiodic L1 reports for semi-persistent simplified SSBs can be triggered for transmission in the PUSCH via at least one of DCI or MAC-CE. Aperiodic reduced SSBs can be received, and aperiodic L1 reports for aperiodic reduced SSBs can be triggered to be sent in the PUSCH via at least one of DCI or MAC-CE.

[0090] Figure 5 This is a call flowchart 500 for wireless communication. Call flowchart 500 may include UE 502 and base station 504. Base station 504 may configure UE 502 using a reduced SSB resource set and instruct UE 502 to activate, deactivate, or trigger at least one reduced SSB or a reduced SSB report. UE 502 may measure the reduced SSB and report the measurement to base station 504. Base station 504 may perform beam management based on the measurement report received from UE 502.

[0091] At 506, UE 502 can receive from base station 504 a configuration indicating a simplified SSB resource set, the simplified SSB resource set indicating at least one resource for receiving simplified SSBs and for measuring at least one parameter associated with the received simplified SSB resource set. The simplified SSB resource set may indicate at least one SSB resource for receiving simplified SSBs and for measuring at least one parameter associated with the received simplified SSB resource set. The configuration may indicate at least one parameter to be measured, wherein the at least one parameter may be measured based on the received configuration. The configuration may indicate a UL resource for sending a measurement report, wherein the measurement report is sent in the indicated UL resource. The configuration may indicate a resource ID associated with each simplified SSB resource in the simplified SSB resource set, wherein UE 502 may receive and measure the simplified SSB resource set based on the received configuration. The configuration may indicate the type of at least one simplified SSB resource in the simplified SSB resource set, wherein the type of the at least one simplified SSB resource includes periodic, aperiodic, or semi-persistent. The configuration received via RRC messages can be applied to periodically reduced SSBs. This configuration can indicate the BWP for receiving at least one reduced SSB resource and measuring at least one parameter associated with the received reduced SSB, and UE 502 can receive and measure the reduced SSB based on the received configuration. In one aspect, the configuration can indicate at least one serving cell ID from which the reduced SSB is received and measured, and UE 502 can receive and measure the reduced SSB based on the received configuration. In another example, UE 502 can send a measurement report to a base station via a serving cell. The configuration can indicate the repetition of symbols for the reduced SSB resources. The configuration can also indicate one or more parameters, including the location of at least one resource in the reduced SSB resource set, one or more symbols and slot offsets of the reduced SSB resource set, the period of at least one resource in the reduced SSB resource set, or one or more time densities and time repetition values ​​for aperiodic reduced SSB resource sets.

[0092] At 507, UE 502 can receive instructions from base station 504 for activating / deactivating or triggering reduced SSB resources configured based on the configuration received at 506. In one aspect, base station 504 can configure the reduced SSB resource set via an RRC message at 506 and send instructions via DCI or MAC-CE for semi-persistently activating / deactivating reduced SSB resources and / or reporting reduced SSB resources. In another aspect, base station 504 can send instructions via DCI or MAC-CE for aperiodically triggering reduced SSB resources and / or reporting reduced SSB resources.

[0093] At 508, UE 502 can receive at least one simplified SSB from base station 504, each of the at least one simplified SSB being received in one symbol of at least one symbol, and each of the at least one simplified SSB including a synchronization signal of the same kind in each of the at least one symbol. That is, the synchronization signal may include one of PSS or SSS. The simplified SSB resource set may indicate at least one simplified SSB resource including at least one symbol associated with the same transmit beam direction from the base station, or at least one simplified SSB resource associated with multiple different transmit beam directions from the base station.

[0094] At 510, UE 502 can measure at least one parameter associated with at least one simplified SSB received at 508. The measured at least one parameter associated with the received simplified SSB may include at least one L1 parameter, and the at least one L1 parameter may include RSRP, RSRQ, SNR, SINR, etc.

[0095] At 514, UE 502 may send a measurement report to base station 504 indicating at least one measured parameter associated with at least one simplified SSB received at 508. The measurement report may include a resource ID associated with the simplified SSB resource in which the simplified SSB was received, and at least one measurement value associated with the at least one measured parameter. Each of the at least one measurement value may include a value independent of or dependent on other measurement values. The measurement report may be sent using a UL resource specified by configuration instructions received at 506. UE 502 may also truncate the measurement report to a maximum number of bits, and the transmitted measurement report may be a truncated measurement report.

[0096] The at least one simplified SSB can be received periodically, and the L1 report can be a periodic L1 report sent periodically in the PUCCH. The at least one simplified SSB can be received periodically, and a semi-persistent L1 report for the periodic simplified SSB can be activated for transmission in the PUCCH via MAC-CE or in the PUSCH via DCI. The at least one simplified SSB can be received semi-persistently, and a semi-persistent L1 report for the semi-persistent simplified SSB can be activated for transmission in the PUCCH via MAC-CE or in the PUSCH via DCI. The at least one simplified SSB can be received periodically, and an aperiodic L1 report for the periodic simplified SSB can be triggered for transmission in the PUSCH via at least one of DCI or MAC-CE. The at least one simplified SSB can be received semi-persistently, and an aperiodic L1 report for the semi-persistent simplified SSB can be triggered for transmission in the PUSCH via at least one of DCI or MAC-CE. The at least one simplified SSB can be received aperiodically, and an aperiodic L1 report for the aperiodic simplified SSB can be triggered to be sent in the PUSCH via at least one of DCI or MAC-CE.

[0097] At 516, base station 504 can perform beam management based on the measurement report sent from UE 502 at 514. That is, base station 504 can use the measurement report based on at least one simplified SSB to switch / adapt its beam to improve performance.

[0098] Figure 6 This is a flowchart 600 of a wireless communication method. This method can be performed by a UE (e.g., UE 104, 502; device 1002). The UE can receive from the base station configurations for a reduced SSB resource set and / or a reduced SSB report, as well as instructions for activating, deactivating, or triggering at least one reduced SSB or reduced SSB report. The UE can measure the at least one reduced SSB and report the measurement to the base station for management purposes.
