[0005] introduction

[0006] 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.

[0007] 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 related to latency, reliability, security, scalability (e.g., with the Internet of Things (IoT), and others). 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.

[0041] Detailed description

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Accordingly, in one or more example 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. Computer-readable media includes computer storage media. Storage media can 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 computer-readable media of the types described above, 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.

[0046] 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.

[0047] 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.

[0048] 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).

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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). The frequencies between FR1 and FR2 are generally referred to as the mid-band frequencies. Although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz band” in various documents and articles. Similar naming issues sometimes arise regarding FR2, although it is different from the Very High Frequency (EHF) band (30GHz–300GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is often (interchangeably) referred to as the “millimeter wave” band in various documents and articles.

[0053] 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, or within the EHF band.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] Refer again Figure 1 In some respects, UE 104 can be configured to operate based on a modified subset of UE capabilities when multiple USIMs are active at UE 104. For example, UE 104 may include an operation component 198 configured to operate based on a modified subset of UE capabilities when multiple USIMs are active at UE 104. UE 104 transmits UE capability information, including a set of UE capabilities, to base station 180 in response to a UE capability query. When multiple Universal Subscriber Identity Modules (USIMs) are active at UE 104, UE 104 transmits UE Assistance Information (UAI) to base station 180, which includes Information Elements (IEs) indicating a modified subset of UE capabilities. When multiple USIMs are active at UE 104, UE 104 operates based on the modified subset of UE capabilities.

[0060] Refer again Figure 1In some aspects, base station 180 can be configured to communicate with UE 104 based on a modified subset of UE capabilities when multiple USIMs are active at UE 104. For example, base station 180 may include a communication component 199 configured to communicate with UE 104 based on a modified subset of UE capabilities when multiple USIMs are active at UE 104. Base station 180 transmits a UE capability query to UE 104. In response to the UE capability query, base station 180 receives UE capability information from UE 104, which includes a set of UE capabilities. When multiple USIMs are active at UE 104, base station 180 receives a UAI from UE 104, which includes an IE indicating a modified subset of UE capabilities. When multiple USIMs are active at UE 104, base station 180 communicates with UE 104 based on the modified subset of UE capabilities.

[0061] 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.

[0062] 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 subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to either DL or UL; or it can be Time Division Duplex (TDD), where subframes within a specific set of subcarriers (carrier system bandwidth) 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.

[0063] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10ms) can be divided into 10 equally sized subframes (1ms). 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 7 or 14 symbols, depending on the time slot configuration. For time slot configuration 0, each time slot may include 14 symbols, while for time slot configuration 1, each time slot may include 7 symbols. Symbols on the DL can be Cyclic Prefix (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 time slot configuration and parameter design. For slot configuration 0, different parameter designs μ of 0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For slot configuration 1, different parameter designs 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Correspondingly, for slot configuration 0 and parameter design μ, there are 14 symbols per slot and 2 symbols per subframe. μ Each time slot. The subcarrier spacing and symbol length / duration vary depending on the design parameters. 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 2DAn example is provided with a slot configuration of 0 (14 symbols per slot) and a parameter design of μ=2 (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) that are frequency-division multiplexed (see [link to relevant documentation]). Figure 2B Each BWP can have specific parameter designs.

[0064] A resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) extending 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.

[0065] 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).

[0066] 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 aforementioned DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the 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.

[0067] 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.

[0068] 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) / negative ACK (NACK) feedback. The PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI.

[0069] 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 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 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.

[0070] 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 modulate an RF carrier with the corresponding spatial stream for transmission.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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 199 combines various aspects.

[0079] In wireless communication systems, a UE can be configured to support multiple Universal Subscriber Identity Modules (USIMs). A UE can be configured to support two or more USIMs, where each USIM can belong to a different network operator. In some instances, a UE supporting dual USIMs can be active on both USIMs (e.g., connected). In such instances, it may be necessary to reduce the capacity on each link compared to a single active USIM. When dual USIMs (or multiple USIMs) are active at the UE, the UE can request reduced capacity or temporary capacity limits. Reduced capacity or temporary capacity limits can be used to prevent or counteract UE overheating and similar temporary events.

[0080] Figure 4Example 400 of a dual-connectivity UE is explained. Example 400 includes UE 402, a first base station BS1 404, and a second base station BS2 406. If in an idle state, UE 402 can select one of the USIMs for the initial request. For example, UE 402 can establish an RRC connection 408 with BS1 404, where the first USIM is associated with BS1 404. At 410, UE 402 can transmit a TDM and / or capability reduction request to BS1 404. In some instances, at 412, UE 402 can initiate an RRC connection establishment with BS2 406, where the second USIM is associated with BS2 408. At 414, UE 402 can transmit TDM and / or capability reduction to BS1 404 and / or BS2 406. At 416, UE 402 can transmit an indication to BS1 404 and / or BS2 406 to cancel TDM and / or capability reduction. In 418, UE 402 can establish a single connection with either BS1 404 or BS2 406.

[0081] When multiple links are active, a UE with multiple USIMs can split RF / baseband resources. If TDM is not used for both downlink and uplink, the UE can split RF / baseband resources. When a UE is active on a second USIM, it can notify or request a capability change for the first USIM. For example, the first request can occur during or after the UE initiates a connection establishment / restore with the second USIM. Further updates can occur as configurations on each link change (e.g., the addition of a secondary cell or partial bandwidth modification). UEs configured to request dynamic capabilities can be in a temporary state, where some capabilities may be limited, for example, due to hardware sharing, interference, or overheating. Dynamic capabilities can be based on RRC signaling, which can degrade the performance of multiple USIMs.

[0082] The aspects presented in this paper provide configurations for enhancing the efficiency of dynamic UE capability signaling for multiple USIMs. For example, the aspects presented in this paper can allow a UE to indicate or request operation using modified UE capabilities, thereby enabling operation based on modified UE capabilities when multiple USIMs are active at the UE.

[0083] Capability changes can depend on the frequency band combination of the two links used, which may change over time. Signaling can limit or minimize interruptions and inefficiencies during the transition until capability reconfiguration is complete. Requests for UE capability changes can be initiated by the UE. For example, the request can be transmitted via UAI, or a new RRC message can be used. In some instances, multiple iterations of convergence on UE capabilities may occur. Multiple negotiations between the UE and the base station can increase latency or cause interruptions on other USIM links. In some instances, capability changes may not be visible to the core network, but in others they may be visible (e.g., profiles).

[0084] Signaling for dynamic UE capabilities can include extending the UAI framework, incremental signaling regarding baseline capacity, pre-configuring multiple capabilities (e.g., profiles), or signaling notification to completely degrade / expand UE capabilities. In some aspects, the UE can be configured to initiate signaling. Negotiation between the UE and the base station can occur; for example, the base station can provide an alternative, or the UE can suggest a modified capability in response to a rejection from the base station. The UE can also be configured to request a new or modified capability for a valid duration, which can result in reduced signaling overhead when the UE reverts to the original capability. For example, when the base station acknowledges receipt of a request for modified capability from the UE, a timer can be started. The UE can request an extension of the timer, and request its termination before expiration based on activity on other links. In some instances, when the timer expires, the UE can revert to the original capability before requesting the modified capability.

[0085] Wireless communication systems (such as NR) can utilize UAI to request different component carrier bandwidths and MIMO layers. This can be used to minimize the impact of UE overheating and for power-saving features. Signaling can be based on RRC signaling; however, the UE can only signal lower capabilities, and the reporting frequency can be controlled by the network.

[0086] The UAI can be extended to include additional parameters or similar messages. For example, a response message can be included to the UAI to suggest replacement parameters or acknowledge a request for replacement parameters. For instance, when multiple USIMs are active at the UE, the UAI can include an IE indicating a modified subset of the UE's capability set that is available. The UAI may request changes to certain capabilities due to overheating at the UE, such as reducedMaxCCs (e.g., DL and UL), reducedMaxBW-FR1 (e.g., reducedMaxBW-FR1), reducedMaxBW-FR2 (e.g., reducedMaxMIMO-LayersFR1) (e.g., UL and DL), and reducedMaxMIMO-LayersFR2 (e.g., DL and UL). UAI may also include the following: idc-Assistance-r16: affected frequencies, drx-Preference-r16: inactive timers, short-cycle and long-cycle timers, short-cycle timers, maxBW-Preference-r16: separately, FR1 and FR2, maxCC-Preference-r16: DL and UL, maxMIMO-LayerPreference-r16, minSchedulingOffsetPreference-r16, or releasePreference-r16.

[0087] In instances where incremental signaling can be utilized, a UE can be configured to request a new value for a capability to be modified. For example, a UE can request a new value for a capability to be modified. Incremental signaling can be applied between RATs. For example, the first USIM can be on LTE, and the second USIM can be on NR Dual Connectivity (DC) (NR-DC), and the capability change can occur on the second USIM, while the UE can detach or reattach on the first USIM. Incremental signaling of the actual UE capability IE (e.g., UE-NR-Capability) can help reduce signaling overhead and enhance flexibility.

[0088] In some instances, a single IE can be configured such that all parameters are "Need ON" or "Need OR," allowing the base station to use previous values ​​or remove a value if no new value is available. In some instances, incremental signaling can allow deletion from baseline capacity. For example, a UE can issue a signal (e.g., UE-NR-Capability-reduce) that may include the capability to be removed from the current capacity. Individual signaling from the UE or the expiration of a timer can reverse the reduction and restore the UE to its original capacity.

[0089] In instances utilizing UE profiles, UE profiles can provide faster adaptation. For example, changes to a new profile can be signaled via Layer 1 (L1) or Layer 2 (L2) signaling. Additional profiles can be configured during the lifetime of a connection. In some instances, profiles can be formed during initial UE capability transfer, which can use a common set of parameters for all profiles or a set of features. Profiles can specify additional parameters. UE profiles can be tailored based on the frequency bands and / or features supported by the base station. For example, during connection setup, the base station can limit such combinations (e.g., based on supported and anticipated configurations) to avoid having an excessive number of profiles. In some instances, feature clusters can be used to further limit signaling size. UE profiles can be stored in the Access Layer (AS) context in inactive mode and can be forwarded to neighboring base stations during mobility.

[0090] In some respects, each profile can be formed as a separate UE capability. In this respect, the UE can signal multiple UE capabilities, each with an index or identifier to be used for future dynamic changes. For example, the parameter UE-CapabilityRAT-ContainerList can include multiple UE capabilities.

[0091] In some respects, each profile can be formed by adding additional capabilities to the baseline capabilities. In this respect, additional IEs can be added or overridden to the baseline capabilities (e.g., UE-NR-Capability) for each baseline. In some respects, such as for band combination (BC) capabilities, the feature set structure can simplify signaling by adding additional feature sets (FS) to each profile. In some respects, each profile can define different values ​​for the IE.

[0092] In some respects, a UE can request a repetition of UE capability transfer. When a change in capabilities is required, a UE can request to initiate a UE capability transfer. For example, a UE can determine changes at its location (such as determining that multiple USIMs are active at the UE) and can initiate a UE capability transfer, allowing the UE to indicate changes in capabilities associated with the determined changes at the UE's location.

Various modifications to these aspects will readily be understood by those skilled in the art, and the universal principles defined herein may be applied to other aspects. Therefore, the claims are not intended to be limited to the aspects shown herein, but are to be granted the full scope consistent with the language of the claims, wherein references to the singular form of an element, unless specifically stated otherwise, are not intended to mean “one and only one,” but rather “one or more.” Terms such as “if,” “when,” and “at the time of” should be interpreted as meaning “under this condition,” rather than implying a direct temporal relationship or reaction. That is, these phrases (e.g., “when”) do not imply an immediate action in response to the occurrence of an action or during the occurrence of an action, but only imply that an action will occur when a condition is met, without requiring a specific or immediate temporal constraint for the action to occur. The term “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as superior to or overriding other aspects. Unless specifically stated otherwise, the term “some / a” refers to one or more. Combinations such as "at least one of A, B, or C", "one or more of A, B, or C", "at least one of A, B, and C", "one or more of A, B, and C", and "A, B, C, or any combination thereof" include any combination of A, B, and / or C, and may include multiple A, multiple B, or multiple C. Specifically, combinations such as "at least one of A, B, or C", "one or more of A, B, or C", "at least one of A, B, and C", "one or more of A, B, and C", and "A, B, C, or any combination thereof" may be only A, only B, only C, A and B, A and C, B and C, or A and B and C, wherein any such combination may include one or more members of A, B, or C. Elements of all aspects described throughout this disclosure that are presently or hereafter known to those skilled in the art are expressly incorporated herein by reference and are intended to be covered by the claims. Furthermore, nothing disclosed herein is intended as a donation to the public, whether or not such disclosure is explicitly stated in the claims. Terms such as “module,” “mechanism,” “element,” and “device” are not necessarily substitutes for the term “apparatus.” Thus, no claim element should be interpreted as an apparatus plus a function unless the element is explicitly stated using the phrase “apparatus for…”.
