[0004] introduction

[0005] 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.

[0006] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the city, country, region, and even global levels. An example 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 adopt them.

[0033] Detailed description

[0034] The detailed description that follows, taken in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent only the configurations in which the concepts described herein can be practiced. This detailed description includes specific details 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 such concepts.

[0035] Several aspects of a telecommunications system will now be described with reference to various apparatuses and methods. These apparatuses and methods will be described in detail below and explained in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0036] As an example, an element, or any part of an element, or any combination of elements, may 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 functionalities described throughout this disclosure. One or more processors in a processing system can execute software. 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, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description languages, or other terms.

[0037] Accordingly, in one or more example embodiments, 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 and not limitation, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage, magnetic disk storage, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium capable of being used to store computer-executable code in the form of instructions or data structures accessible to a computer.

[0038] While aspects are described herein by way of example, those skilled in the art will understand that additional implementations and use cases can arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, implementations and / or devices may arise via integrated chip implementations and other non-modular component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / shopping devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to particular use cases or applications, broad applicability of the described innovations is possible. Implementations 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 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 requires several components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The innovations described herein are intended to be implemented 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.

[0039] Figure 1 This is a diagram illustrating 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 macrocells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macrocells include base stations. Small cells include femtocells, picocells, and microcells.

[0040] 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: user data delivery, radio channel cryptography and cryptography decoding, 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), subscriber and equipment tracking, RAN Information Management (RIM), paging, location, and delivery of alarm messages. Base station 102 can communicate with each other directly or indirectly (e.g., via EPC 160 or core network 190) on 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.

[0041] Base station 102 can wirelessly communicate with UE 104. Each base station 102 can provide communication coverage for its respective geographical coverage area 110. Overlapping geographical coverage areas 110 may exist. For example, small cell 102' may have coverage areas 110' that overlap with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. The heterogeneous network may also include a Home Evolved B Node (eNB) (HeNB) that can provide services to a restricted group referred to as a Closed Subscriber Group (CSG). 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. These communication links may use one or more carriers. For each carrier allocated in a total of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum with a bandwidth of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.). These carriers may or may not be adjacent to each other. The allocation of carriers 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 may be referred to as the primary cell (PCell), and the secondary component carrier may be referred to as the secondary cell (SCell).

[0042] Some UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 may use DL / UL WWAN spectrum. D2D communication link 158 may use one or more sidelink channels, such as the 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 a wide variety of wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0043] The wireless communication system may further include a Wi-Fi access point (AP) 150 communicating with a Wi-Fi station (STA) 152 via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) before communication to determine whether the channel is available.

[0044] 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.) used by Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can enhance access network coverage and / or increase access network capacity.

[0045] The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). Although a portion of FR1 is greater than 6GHz, it is generally (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes arise regarding FR2; although different from the Very High Frequency (EHF) band (30GHz–300GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is generally (interchangeably) referred to as the “millimeter wave” band in various documents and articles.

[0046] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands of these IF bands as the frequency range designation FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending 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 frequency bands have been designated as the frequency range designations FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0047] In light of the foregoing, unless otherwise stated, it should be understood that, as used herein, the term "sub-6GHz" and the like can broadly refer to frequencies less than 6GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise stated, it should be understood that, as used herein, the term "millimeter wave" and the like can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a or FR4-1 and / or FR5, or within the EHF band.

[0048] Whether it is a small cell 102' or a large cell (e.g., a macro base station), base station 102 may include and / or be referred to as an eNB, gB node (gNB), or another type of base station. Some base stations (such as 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 frequencies 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. Base station 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.

[0049] Base station 180 may transmit beamformed signals to UE 104 in one or more transmission directions 182'. UE 104 may receive beamformed signals from base station 180 in one or more reception directions 182'. UE 104 may also transmit beamformed signals to base station 180 in one or more transmission directions. Base station 180 may receive beamformed signals from UE 104 in one or more reception directions. Base station 180 / UE 104 may perform beam training to determine the optimal reception and transmission directions for each of base station 180 / UE 104. The transmission and reception directions of base station 180 may be the same or different. The transmission and reception directions of UE 104 may be the same or different.

[0050] 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 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Generally, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are delivered 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. The BM-SC 170 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 can be used to distribute MBMS traffic to base station 102 within a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0051] The 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 the core network 190. Generally, 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 services 197. IP services 197 may include the Internet, intranet, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming (PSS) services, and / or other IP services.

[0052] Base stations may include and / or be referred to as gNB, B-node, eNB, access point, base transceiver station, radio base station, radio transceiver, transceiver function, 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 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, gas pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similar functional devices. Some UE 104 may be referred to as IoT devices (e.g., parking timers, oil pumps, ovens, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable term. In some scenarios, the term UE may also apply to one or more accompanying devices, such as in a device constellation arrangement. One or more of these devices may access the network jointly and / or individually.

[0053] Refer again Figure 1 In some respects, UE 104 can be configured to utilize a permitted periodicity value that is not a multiple or fraction of a time slot. For example, UE 104 may include a configuration component 198 configured to receive configuration for a configured periodicity. UE 104 may receive configuration for a configured periodicity from base station 180, which is used to communicate with the base station based on the corresponding periodicity. UE 104 may communicate with the base station based on the configured periodicity associated with the configured periodicity, which is one of the following: receiving multiple physical downlink shared channels (PDSCH) associated with the configured periodicity or transmitting multiple physical uplink shared channels (PUSCH) associated with the configured periodicity based on the corresponding configured periodicity, wherein the configured periodicity is a non-integer multiple or non-integer fraction of a time slot.

[0054] Refer again Figure 1In some respects, base station 180 may be configured to configure the UE to utilize periodic values ​​that are not multiples or fractions of time slots. For example, base station 180 may include configuration component 199 configured to transmit configuration for a configured periodicity. Base station 180 transmits the configuration for the configured periodicity to UE 104, which is used to communicate with UE 104 based on the corresponding periodicity. Base station 180 communicates with UE 104 based on the configured periodicity associated with the configured periodicity, which is one of the following: transmitting a plurality of PDSCHs associated with the configured periodicity or receiving a plurality of PUSCHs associated with the configured periodicity based on the corresponding configured periodicity, wherein the configured periodicity is a non-integer multiple or non-integer fraction of a time slot.

[0055] While the following description may focus on 5G NR, the concepts described herein are applicable to other similar areas such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0056] Figure 2A This is a diagram 200 illustrating an example of the first subframe within the 5G NR frame structure. Figure 2B Figure 230 is an example illustrating the DL channel within a 5G NR subframe. Figure 2C This is a diagram 250 illustrating an example of the second subframe within the 5G NR frame structure. Figure 2D Figure 280 illustrates an example of the UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD), where, for a given set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to either DL or UL; or it can be Time Division Duplex (TDD), where, for a given set of subcarriers (carrier system bandwidth), subframes within that 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) and subframe 3 is configured with slot format 1 (both UL), where D is DL, U is UL, and F is provided for flexible use between DL and 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 to have a slot format 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 5G NR frame structures for TDD.

[0057] Figure 2A-2D The frame structure has been explained, 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 equally 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. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal CP or extended CP. For normal CP, each time slot may include 14 symbols, while for extended CP, each time slot may include 12 symbols. Symbols on the DL can be CP Orthogonal Frequency Division Multiplexing (OFDM) (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 parameter design. The parameter design defines the subcarrier spacing (SCS) and, in effect, the symbol length / duration, which is equal to 1 / SCS.

[0058]

[0059] For a normal CP (14 symbols / slot), different parameter designs μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For an extended CP, parameter design 2 allows 4 slots per subframe. Correspondingly, for the normal CP and parameter design μ, there are 14 symbols / slot and 2... μ One time slot / subframe. The subcarrier spacing can be equal to 2. μ*15kHz, where μ is the parameter design from 0 to 4. Thus, parameter design μ=0 has a subcarrier spacing of 15kHz, while parameter design μ=4 has a subcarrier spacing of 240kHz. Symbol length / duration is inversely correlated with subcarrier spacing. Figures 2A to 2D An example of a normal CP with 14 symbols per time slot and a parameter design of μ=2 with 4 time slots per subframe is provided. The time slot duration is 0.25ms, the subcarrier spacing is 60kHz, and the symbol duration is approximately 16.67μs. Within the frame set, there may be one or more different bandwidth portions (BWPs) that are frequency-division multiplexed (see [link to relevant documentation]). Figure 2B Each BWP can have specific parameter designs and CP (normal or extended).

[0060] 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.

[0061] like Figure 2A As explained in the text, some REs carry reference (pilot) signals (RS) for the UE. RSs may include demodulation RS (DM-RS) for channel estimation at the UE (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS). RSs may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0062] Figure 2BExamples of various DL channels within a subframe of a frame are explained. 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 includes 6 RE Groups (REGs), and each REG includes 12 coherent REs in the OFDM symbols of the RB. A PDCCH within a BWP may 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 shared search space, a UE-specific search space) during PDCCH monitoring 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 across 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 identity. The Secondary Synchronization Signal (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 Identity Group Number and radio frame timing. Based on the Physical Layer Identity and the 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 group with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the number of 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 System Information Block (SIB)), and paging messages.

[0063] As in Figure 2C As explained, 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 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 DM-RS can be transmitted in the first or first two symbols of the PUSCH. The PUCCH DM-RS can be transmitted in different configurations depending on whether a short or long PUCCH is being transmitted and on the specific PUCCH format used. The UE can transmit a probe 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 combs. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0064] Figure 2DExamples of various UL channels within a subframe of the explanatory frame. 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), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (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.

[0065] Figure 3 This is a block diagram showing the communication between base station 310 and UE 350 in the access network. In the DL, IP packets from EPC160 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 of UE measurement reports; PDCP layer functionality associated with header compression / decompression, security (cryptography, cryptographic decoding, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with upper-layer packet data unit (PDU) delivery, 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 MAC SDUs onto transport blocks (TBs), demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority differentiation.

[0066] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functionality 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) 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-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time-domain OFDM symbol stream. The OFDM stream is spatially precoded to generate multiple spatial streams. Channel estimates from channel estimator 374 can be used to determine coding and modulation schemes and for spatial processing. The channel estimates can be derived from reference signals and / or channel condition feedback transmitted by 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.

[0067] At UE 350, each receiver 354RX receives signals via its respective antenna 352. Each receiver 354RX 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 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, 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 on each subcarrier, along with the reference signal, are recovered and demodulated by determining the signal constellation points most likely to be transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. These soft decisions are then decoded and deinterleaved to recover the original data and control signals transmitted by base station 310 over the physical channel. This data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0068] 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 between transport and logical channels, packet reassembly, cipher decoding, header decompression, and control signal processing 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.

[0069] Similar to the functionality described in conjunction with DL transmissions performed by base station 310, controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) capture, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (cryptography, cryptographic decoding, 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 MAC SDUs onto TBs, demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel priority differentiation.

[0070] 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 to facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0071] 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.

[0072] 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 between transport and logical channels, packet reassembly, cipher decoding, header decompression, and control signal processing to recover IP packets from the UE 350. IP packets from the controller / processor 375 may 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.

[0073] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform and Figure 1 The 198 combines various aspects.

[0074] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform operations related to... Figure 1 The 198 combines various aspects.

[0075] Wireless communication systems (such as, but not limited to, 5G NR) can support SPS in the downlink and ULCG in the uplink to serve periodic traffic. Two types of ULCG, Type 1 and Type 2, are supported in NR. In Type 1, all parameters are configured for PUSCH transmission via RRC and activation is not required. In Type 2, RRC signaling uses a set of transmission parameters to configure permission. Transmissions can be activated, reactivated, or released by DCI.

[0076] NR's frame / slot structure is configured to include 100 frames per second, with 10 / 20 / 40 / 80 slots per frame, depending on the subcarrier spacing (e.g., 15, 30, 60, 120 kHz, respectively). For downlink SPS, the minimum periodicity can include one slot. For ULCG, the minimum periodicity can include two symbols. Some wireless systems (such as Extended Reality (XR) and Time-Sensitive Networks (TSN)) have periodicity that is not a multiple of NR's slots. For example, XR has a periodicity of 1 / 60 or 1 / 120 of a second (e.g., 60 / 120 packets per second), but the periodicity of SPS and ULCG in NR is not aligned with XR's traffic arrival. TSN has a similar traffic arrival pattern to XR (e.g., 120 packets per second), but with a more stringent latency. A periodicity of 1 / 120th of a second corresponds to 8.3333 time slots. Therefore, if data arrives at intervals of 8.3333 time slots, the periodicity should be aligned with these time slots. Otherwise, for some data packets, the UE may have to wait a certain amount of time before it has an opportunity to transmit or receive the data packet, which can lead to delays. These delays occur because the periodicity of the transmission timing is not aligned with the incoming traffic.

[0077] The aspects presented in this article provide configuration options for periodicity values ​​that are not multiples or fractions of time slots. Configuring periodicity values ​​to be non-multiples or fractions of time slots allows periodicity to be aligned with traffic.

[0078] In some instances, configured permission (e.g., SPS or ULCG) may have a periodicity value that is not a multiple or fraction of a time slot. Periodicity can be configured according to a combination of time slots and symbols. For example, periodicity could have X time slots + Y symbols. In some aspects, setting the values ​​to X=8 and Y=4 can be used to support 120 packets per second. In some aspects, periodicity can be configured based on time. For example, periodicity could be set to 1 / Z seconds, where Z can be set to 60 or 120. In such instances, the UE can use the first activated or configured permission timing as a reference point and then determine the starting symbol of the k-th PDSCH or PUSCH as following the first symbol in the first PDSCH or PUSCH. At each symbol location. In some respects, the UE can target the ratio. Use the functions Ceil() or Floor() instead of Round to determine the symbol index, where This indicates the number of OFDM symbols per second in the corresponding subcarrier interval of the serving cell configured with configuration approval (e.g., SPS or ULCG). In some aspects, the UE may determine the starting symbol of the k-th PDSCH or PUSCH as the first symbol after (K-1) / Z seconds from the first symbol in the first PDSCH or PUSCH configured in SPS or ULCG. In such instances, the UE may determine the first symbol of the k-th PDSCH / PUSCH as after the first symbol of the first PDSCH / PUCCH. At the k-th symbol location. In some aspects, the UE can determine the first symbol of the k-th PDSCH / PUSCH as following the first symbol of the (K-1)-th PDSCH / PUSCH (e.g., a previous transmit / receive opportunity). At the (K-1)th symbol. Thus, the UE can be configured to determine the Kth PDSCH / PUSCH from the (K-1)th PDSCH / PUSCH. In some aspects, the UE can target the ratio. Use the function Ceil() or Floor() instead of Round to determine the first symbol index of the Kth PDSCH / PUSCH from the (K-1)th PDSCH / PUSCH (e.g., previous transmit / receive opportunities).

[0079] Figure 4 This is example 400 of granting permission. The base station can configure permission via RRC signaling. The base station can instruct the UE to receive or transmit the first transmission in time slot 402 via DCI. Figure 4 In Example 400, time slot 402 can be the first time slot in which an SPS or ULCG timing sequence can begin. The base station can also indicate a time-domain resource allocation 404 within the time slot (e.g., ULCG PUSCH or SPS PDSCH transmission). Time slot 402 can include 14 OFDM symbols. In Example 400, the time-domain resource allocation 404 can begin with symbol 2, such that the first transmission or reception occurs at symbol 2, and can have a length of, for example, 7 symbols. If the periodicity is not a multiple of the time slot, then in the next timing, the start of the next PDSCH or PUSCH transmission will not be in the same symbol as the first PDSCH or PUSCH transmission. Figure 4 In Example 400, the next transmission will begin at symbol 9 and may end at symbol 15. However, the transmission opportunity will cross the time slot boundary because symbol 15 exceeds the time slot boundary.

[0080] To overcome the problem of transmission opportunities crossing time slot boundaries due to periodicity not being a multiple of time slots, the UE can delay PDSCH or PUSCH transmissions to the next time slot and use the symbols indicated by the Start and Length Indication (SLIV) in the active DCI or RRC configuration in the corresponding time slot. In some aspects, the UE can allow ULCG PUSCH or SPSPDSCH transmissions to reside across time slot boundaries. In such instances, a PUSCH or PDSCH can be split into two PUSCHs or PDSCHs. Each of the two PUSCHs or PDSCHs can carry the same transport block (TB) or data packets.

[0081] Figure 5 Example 500 is an example of permitted configuration. When a base station is configured with SPS or ULCG, the base station can use patterns and long periodicity to configure SPS / ULCG timing, where there are multiple timings within the long period 502. Figure 5 In Example 500, to support 120 packets per second (e.g., 0.5 ms in a time slot) over a 30 kHz subcarrier spacing, the base station can configure a longer period equal to 50 time slots and define three timings 502 within this long period. These three timings can have gaps of 16, 16, and 18 time slots, respectively. This can be defined by specifying a first timing (e.g., utilizing a time slot offset indicated in the active DCI) and configuring the gap between the first and second timings, and the interval between the second and third timings, via RRC signaling. For example, the base station can configure a gap parameter (e.g., 16 time slots), and the UE can apply the same gap to all PUSCH / PDSCH timings within the long period. The base station can also configure the number of timings in each long period. In another example, the base station can configure the gap between the first and second timings separately, and configure the interval between the second and third timings. These gaps can include the same or different values ​​(e.g., the gap between the first and second timings is 16 time slots, while the interval between the second and third timings is 17 time slots). In some aspects, base stations can define time slot indices or time slot offsets for three time periods over a long period. Figure 5 Example 500 includes three timings 502 within three time slots 504, but this disclosure is not intended to be limited to the aspects disclosed herein. In some aspects, the number of timings may be greater than or less than three, and the number of time slots may be greater than or less than three.

[0082] Figure 6Example 600 is an example of permitted configuration. A base station can be configured with multiple SPS / ULCG configurations (e.g., 602, 604, 606), each with a long periodicity and a different start offset. Multiple SPS / ULCGs can be configured to share several parameters in the configuration (e.g., periodicity, PUCCH resources for HARQ-ACK feedback, MIMO scheme, demodulation reference signal (DMRS) configuration, etc.). Multiple SPS / ULCGs sharing several parameters can be used for interleaved SPS / ULCG sets. In some aspects, DCI can be configured to jointly activate or deactivate SPS / ULCG configurations. Jointly activating or deactivating SPS / ULCG configurations with DCI allows SPS / ULCG configurations to serve the same traffic. For example, in... Figure 6 In Example 600, when SPS1 602 is activated, the base station should also activate SPS2 604 and SPS3 606. Figure 6 In Example 600, three SPSs can be configured by the base station (e.g., SPS1 602, SPS2 604, SPS3 606) and can have offsets 608 of 16, 16, and 18 time slots respectively. In some aspects, such as when multiple SPS configurations can be activated by the same active DCI, the UE can apply the same set of parameters indicated in the control fields of the DCI to all SPS configurations. In some aspects, the control fields may include frequency domain resource allocation, time domain resource allocation, MIMO scheme, DMRS / PTRS configuration, antenna port, precoder, or k1 (PDSCH to HARQ ACK timing). The control fields may include other parameters or settings, and this disclosure is not intended to be limited to the aspects disclosed herein. Figure 6 Example 600 includes three SPS timings within three time slots, but this disclosure is not intended to be limited to the aspects disclosed herein. In some aspects, the number of SPS or ULCG timings may be greater than or less than three, and the number of time slots may be greater than or less than three.

[0083] Figure 7 This is a call flow diagram 700 showing the signaling between UE 702 and base station 704. Base station 704 can be configured to provide cellular services. UE 702 can be configured to communicate with base station 704. For example, in... Figure 1 In the context of this, base station 704 may correspond to base station 102 / 180, and accordingly, the cellular cell may include a geographical coverage area 110 in which communication coverage is provided and / or a small cellular cell 102' having coverage area 110'. Furthermore, UE 702 may correspond to at least UE 104. In another example, in Figure 3 In the context of UE 704, UE 704 can correspond to UE 310, and UE 702 can correspond to UE 350.

[0084] As explained in 706, base station 704 transmits a configuration for periodicity granted by configuration. Base station 704 may transmit the configuration for periodicity granted by configuration to UE 702. UE 702 may receive the configuration for periodicity granted by configuration from base station 704. This configuration grant may be used to communicate with UE 702 based on the corresponding periodicity. In some aspects, the configuration grant includes a ULCG. The ULCG may be used to receive multiple PUSCHs from UE 702 based on the corresponding periodicity. The ULCG may be used by UE 702 to transmit multiple PUSCHs to base station 704 based on the corresponding periodicity. The configuration grant may include at least one SPS. The SPS may be used to transmit multiple PDSCHs to UE 702 based on the corresponding periodicity. The SPS may be used by UE 702 to receive multiple PDSCHs from base station 704 based on the corresponding periodicity.

[0085] In some aspects, base station 704 may transmit configuration for at least one configured periodicity. Base station 704 may transmit configuration for at least one configured periodicity to UE 702. UE 702 may receive configuration for at least one configured periodicity from base station 704. Each of the at least one configured periodicity may be used to communicate with UE 702 based on the corresponding periodicity. In some aspects, the at least one configured periodicity may include at least one ULCG. Each of the at least one ULCG may be used to receive multiple PUSCHs transmitted by UE 702 based on the corresponding periodicity. Each of the at least one ULCG may be used by UE 702 to transmit multiple PUSCHs to base station 704 based on the corresponding periodicity. In some aspects, the at least one configured periodicity may include at least one SPS. Each of the at least one SPS may be used by base station 704 to transmit multiple PDSCHs to UE 702 based on the corresponding periodicity. Each of the at least one SPS can be used by UE 702 to receive multiple PDSCHs transmitted from base station 704 based on the corresponding periodicity.

[0086] As explained in 708, base station 704 can transmit a DCI to UE 702 to activate or deactivate interleaved SPS or ULCG sets. UE 702 can receive a DCI from base station 704 to activate or deactivate interleaved SPS or ULCG sets. This DCI can be configured to jointly activate or deactivate interleaved SPS or ULCG sets at the same periodicity.

[0087] As explained in 710, base station 704 and UE 702 can communicate with each other based on a configured periodicity. This communication can be one of the following: transmitting multiple PDSCHs associated with the configured permission to UE 702 based on the corresponding configured periodicity, or receiving multiple PUSCHs associated with the configured permission from UE 702 based on the corresponding configured periodicity. This communication can also be one of the following: receiving multiple PDSCHs associated with the configured permission from base station 704 based on the corresponding configured periodicity, or transmitting multiple PUSCHs associated with the configured permission to base station 704 based on the corresponding configured periodicity. The configured periodicity can be a non-integer multiple or a non-integer fraction of the time slots. In some aspects, the configured periodicity may include X time slots and Y symbols, where X ≥ 0 and 0 < Y < 14. In some aspects, the configured periodicity may be 1 / Z seconds, where Z is an integer. The starting symbol may be determined based on 1 / Z. The starting symbol can be rounded up or down to a symbol index based on 1 / Z. The first configured to be allowed transmission of this starting symbol can be based on this configured permission. In some aspects, Z = n * 60, where n is an integer greater than or equal to 1. In some aspects, Z = n * 30 or Z = n * 90, where n is an integer greater than or equal to 1. In some aspects, communicating with base station 704 based on configured periodicity may include: when communication based on configured periodicity extends across time slot boundaries, the UE 702 delays the communication until the next time slot. In some aspects, communicating with UE 702 based on configured periodicity may include: when communication based on configured periodicity extends across time slot boundaries, receiving the delayed communication transmitted by UE 702 in the next time slot. In some aspects, communicating between UE 702 and base station 704 based on configured periodicity may include: when communication based on configured periodicity extends across time slot boundaries, communicating in multiple adjacent time slots. These multiple adjacent time slots carry the same TB or data packets.

[0088] In some aspects, base station 704 and UE 702 may communicate with each other based on a configured periodicity associated with each of the at least one configured permission. This communication may be one of the following: base station 704 transmitting multiple PDSCHs associated with each of the at least one configured permission to UE 702 based on the corresponding configured periodicity, or base station 704 receiving multiple PUSCHs associated with each of the at least one configured permission from UE 702 based on the corresponding configured periodicity. This communication may also be one of the following: UE 702 receiving multiple PDSCHs associated with each of the at least one configured permission from base station 704 based on the corresponding configured periodicity, or transmitting multiple PUSCHs associated with each of the at least one configured permission from UE 702 to base station 704 based on the corresponding configured periodicity. The configured periodicity can be one of the following: an integer multiple of time slots, wherein the timing pattern within the periodicity includes at least two timings with different numbers of time slots; or a set of periodicities for interleaved SPS or ULCG sets, wherein at least two periodicities are identical. In some aspects, the configured periodicity can be an integer multiple of time slots, wherein the timing pattern within the periodicity includes at least two timings starting in different time slots within each period. Base station 704 can transmit a time slot indication of a first timing to UE 702. UE 702 can receive the time slot indication of the first timing from base station 704. UE 702 can determine the time slot offsets of the second and third timings based on the configured time slot offset and the time slot indication of the first timing. In some aspects, the configured periodicity can be a set of periodicities for interleaved SPS or ULCG sets, wherein at least two periodicities are identical.

[0089] Figure 8 This is a flowchart 800 of a wireless communication method. The method can be performed by a UE or a component of a UE (e.g., UE 104, 702; device 1102; cellular baseband processor 1104, which may include memory 360 and may be the entire UE 350 or components of UE 350 (such as TX processor 368, RX processor 356, and / or controller / processor 359)). One or more of the described operations may be omitted, interchanged, or performed simultaneously. This aspect allows the UE to utilize permitted periodic values ​​that are not multiples or fractions of time slots.

[0090] At 802, the UE may receive configuration for periodicity granted by configuration. For example, 802 may be performed by configuration component 1140 of device 1102. The UE may receive configuration for periodicity granted by configuration from a base station. This configuration grant may be used to communicate with the base station based on the corresponding periodicity. In some aspects, configuration grant includes uplink configuration grant (ULCG). The ULCG may be used to transmit multiple PUSCHs based on the corresponding periodicity. In some aspects, configuration grant includes at least one semi-persistent scheduling (SPS). The SPS may be used to receive multiple PDSCHs based on the corresponding periodicity.

[0091] At 804, the UE may communicate with the base station based on a configured periodicity associated with the configured permission. For example, 804 may be performed by the communication component 1142 of device 1102. This communication may be one of the following: receiving multiple Physical Downlink Shared Channels (PDSCHs) associated with the configured permission based on a corresponding configured periodicity, or transmitting multiple Physical Uplink Shared Channels (PUSCHs) associated with the configured permission based on a corresponding configured periodicity. The configured periodicity may be a non-integer multiple or a non-integer fraction of a time slot. In some aspects, the configured periodicity may include X time slots and Y symbols, where X ≥ 0 and 0 < Y < 14. In some aspects, the configured periodicity may be 1 / Z seconds, where Z is an integer. The starting symbol may be determined based on 1 / Z. The starting symbol may be rounded up or down to a symbol index based on 1 / Z. The starting symbol of the first configured permission transmission may be based on the configured permission. In some aspects, Z = n * 60, where n is an integer greater than or equal to 1. In some aspects, Z = n * 30 or Z = n * 90, where n is an integer greater than or equal to 1. In some aspects, communicating with the base station based on this configured periodicity may include delaying the communication until the next time slot when the communication based on the configured periodicity extends across time slot boundaries. In some aspects, communicating with the base station based on this configured periodicity may include communicating in multiple adjacent time slots when the communication based on the configured periodicity extends across time slot boundaries. These multiple adjacent time slots may carry the same transport block (TB) or data packets.

[0092] Figure 9This is a flowchart 900 of a wireless communication method. The method can be performed by a UE or a component of a UE (e.g., UE 104, 702; device 1102; cellular baseband processor 1104, which may include memory 360 and may be the entire UE 350 or components of UE 350 (such as TX processor 368, RX processor 356, and / or controller / processor 359)). One or more of the described operations may be omitted, interchanged, or performed simultaneously. The method can be configured to grant timing using a pattern with multiple timings over a long period.

[0093] At 902, the UE may receive configuration for at least one configured periodicity. For example, 902 may be performed by the configuration component 1140 of device 1102.
