Technical Field

[0002] This invention relates generally to communication systems, and more specifically to techniques for performing blind detection at user equipment (UE). Background Technology

[0003] The statements in this section are provided only as background information in relation to the present invention and may not constitute prior art.

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the municipal, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Evolution of Mobile Broadband program issued by the Third Generation Partnership Project (3GPP), designed to meet new requirements related to latency, reliability, security, scalability (e.g., the Internet of Things, IoT), and other requirements. Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. 5G NR technology requires further improvements. These improvements may also apply to other multiple access technologies and telecommunications standards that adopt them. Summary of the Invention

[0006] The following is a simplified summary of one or more aspects to provide a basic understanding of these aspects. This summary is not a comprehensive overview of all anticipated aspects, nor is it intended to identify key or essential elements of all aspects, nor to depict the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that follows.

[0007] In one aspect of the invention, a method, computer-readable medium, and apparatus are provided. The apparatus may be a base station. The base station allocates a time slot group comprising multiple consecutive time slots based on an operating subcarrier spacing. The start and end boundaries of the time slot group are each aligned with the boundaries of the time slots using a reference subcarrier spacing. The base station determines a limit on the total blind detection performed by the UE in the time slot group and a limit on the total non-overlapping control-channel elements (CCEs) monitored by the UE, both associated with the operating subcarrier spacing. The base station transmits a configuration for allocating P blind detections on M non-overlapping CCEs in the time slot group between a set of component carriers of the UE using the operating subcarrier spacing, where P is an integer not greater than the total blind detection limit and M is an integer not greater than the total number of non-overlapping CCEs limit.

[0008] In another aspect of the invention, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE allocates a time slot group comprising a plurality of consecutive time slots based on an operating subcarrier interval. The start boundary and end boundary of the time slot group are each aligned with the boundary of the time slot using a reference subcarrier interval. The UE receives a configuration that allocates blind detection on non-overlapping CCEs in a time slot group of a set of component carriers of the UE using the operating subcarrier interval. When (a) the total number of blind detections (including the next set of blind detections) performed by the UE on that component carrier in the time slot group does not exceed a limit on the total blind detections associated with the operating subcarrier interval and (b) the total number of non-overlapping CCEs (including the next set of non-overlapping CCEs) monitored by the UE on that component carrier in the time slot group does not exceed a limit on the total non-overlapping CCEs associated with the operating subcarrier interval, the UE performs the next set of blind detections on the next set of non-overlapping CCEs on a given component carrier of the component carrier group according to the configuration in the time slot group.

[0009] According to the blind detection method and related user equipment proposed in this invention, the UE PDCCH monitoring capability in 480 kHz and 960 kHz for single-cell and multi-cell operation can be improved under the concept of the proposed time slot group.

[0010] To achieve the foregoing and related objectives, one or more aspects include the features fully described below and specifically pointed out in the claims. The following description and drawings set forth certain illustrative features of one or more aspects in detail. However, these features represent only a few of the various ways in which the principles of each aspect can be employed, and this description is intended to include all such aspects and their equivalents.

[0022] The detailed description that follows, taken in conjunction with the accompanying drawings, is intended as a description of various configurations and not as representing the only configuration in which the concepts described in the invention can be practiced. The detailed description includes specific details intended 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 cases, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0023] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and methods. These apparatuses and methods will be described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0024] For example, an element, any part of an element, or any combination of elements may be implemented as a “processing system” including one or more processors. 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, systems on a chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this invention. One or more processors in a processing system may execute software. Software should be interpreted broadly as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, application programs, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc., whether referring to software, firmware, middleware, microcode, hardware description languages, or others.

[0025] Therefore, in one or more example aspects, the described functionality can be implemented in hardware, software, or any combination thereof. If implemented in software, these functions can 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 can be any available medium that is 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 disk storage, magnetic disk storage, other magnetic storage devices, combinations of computer-readable media of the types described above, or any other medium that can be used to store computer-executable code in the form of computer-accessible instructions or data structures.

[0026] Figure 1This 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 macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells include base stations. Small cells include femtocells, picocells, and microcells.

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

[0028] Base station 102 can wirelessly communicate with UE 104. Each of base stations 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes small cells and macro cells can be referred to as a heterogeneous network. The heterogeneous network may also include Home Evolved Node B (eNB) (HeNB), which 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. Communication link 120 may use multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. Base station 102 / UE 104 may use spectrum (x component carriers) with a bandwidth of up to 7 MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) allocated per carrier in a total carrier aggregation of up to Y x MHz for transmission in each direction. Carriers may or may not be adjacent to each other. Carrier allocation may be asymmetrical for DL ​​and UL (e.g., more or fewer carriers may be allocated to DL than to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell) and the secondary component carriers may be referred to as secondary cells (SCells).

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

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

[0031] Cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, cell 102' can employ NR and use the same 5 GHz unlicensed spectrum as Wi-Fi AP 150. Employing NR in unlicensed spectrum can extend the coverage and / or increase the capacity of the access network.

[0032] Base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), can include an eNB, gNodeB (gNB), or other types of base stations. Some base stations, such as gNB 180, can operate in the conventional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near-mmW frequencies that communicate with UE 104. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 can be referred to as an mmW base station. Extremely high frequency (EHF) is a radio frequency portion of the electromagnetic spectrum. EHF ranges from 30 GHz to 300 GHz, with wavelengths between 1 mm and 10 mm. Radio waves in this band can be referred to as millimeter waves. Near-millimeter waves may extend down to frequencies of 3 GHz with wavelengths of 100 mm. The super high frequency (SHF) band extends between 3 GHz and 30 GHz and is also known as centimeter waves. Communication using millimeter-wave / near-millimeter-wave radio frequency bands (e.g., 3 GHz - 300 GHz) suffers from extremely high path loss and short range. The mmW base station 180 can compensate for the extremely high path loss and short range by utilizing beamforming 182 with the UE 104.

[0033] Base station 180 can transmit beamformed signals to UE 104 in one or more transmit directions 108a. UE 104 can receive beamformed signals from base station 180 in one or more receive directions 108b. UE 104 can also transmit beamformed signals to base station 180 in one or more transmit directions. Base station 180 can receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 can perform beamforming to determine the optimal receive and transmit directions for each base station 180 / UE 104. The transmit and receive directions of base station 180 can be the same or different. The transmit and receive directions of UE 104 can be the same or different.

[0034] EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. MME 162 can communicate with the Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. BM-SC 170 can provide functionality for MBMS user service provisioning and delivery. BM-SC 170 can serve as an entry point for content provider MBMS transmissions, can be used to authorize and initiate MBMS bearer services within a public landmobile network (PLMN), and can be used to schedule MBMS transmissions. MBMS gateway 168 can be used to distribute MBMS services to base station 102 within a Multicast Broadcast Single Frequency Network (MBSFN) area belonging to a broadcast-specific service, and can be responsible for session management (start / stop) and collection of billing information related to eMBMS.

[0035] The core network 190 may include an Access and Mobility Management Function (AMF) 192, other AMFs 193, a Location Management Function (LMF) 198, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 can communicate with the Unified Data Management (UDM) 196. The AMF 192 is the control node that handles signaling between the UE 104 and the core network 190. Typically, the SMF 194 provides QoS streaming and session management. All user Internet Protocol (IP) packets are transmitted through the UPF 195. The UPF 195 provides UE IP address allocation and other functions. The UPF 195 connects to an IP service 197. The IP service 197 may include the Internet, intranet, IMS, PS streaming service, and / or other IP services.

[0036] A base station may also be referred to as a gNB, Node B, evolved Node B (eNB), access point, base transceiver, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), transmit reception point (TRP), or some other suitable terminology. 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, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some of the devices in UE 104 may be referred to as IoT devices (e.g., parking timers, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, mobile phone, user agent, mobile client, client, or some other suitable terminology.

[0037] Although this invention may refer to 5G New Radio (NR), it is applicable to other similar fields, such as LTE, LTE-Advanced (LTE-A), CDMA, Global System for Mobile communications (GSM), or other wireless / radio access technologies.

[0038] Figure 2This is a block diagram illustrating communication between base station 210 and UE 250 in the access network. In the DL, IP packets from EPC 160 can be provided to controller / processor 275. Controller / processor 275 implements Layer 3 and Layer 2 functions. Layer 3 includes the radio resource control (RRC) layer, and Layer 2 includes the packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, and medium access control (MAC) layer. The controller / processor 275 provides RRC layer functions associated with broadcast system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), mobility between radio access technologies (RATs), and measurement configuration of UE measurement reports; PDCP layer functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with upper-layer packet data unit (PDU) transmission, 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 mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, and HARQ. The MAC layer functions associated with error correction, priority processing, and logical channel priority.

[0039] The transmit (TX) processor 216 and receive (RX) processor 270 implement Layer 1 functions associated with various signal processing functions. Layer 1 includes a physical (PHY) layer, which may include error detection on the transport channel, forward error correction (FEC) encoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, physical channel modulation / demodulation, and MIMO antenna processing. The TX processor 216 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), and M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols can then be split into parallel streams. Each stream can then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then combined using an inverse fast fourier transform (IFFT) to generate a physical channel carrying a stream of time-domain OFDM symbols. The OFDM streams are spatially precoded to generate multiple spatial streams. Channel estimates from channel estimator 274 can be used to determine coding and modulation schemes, as well as for spatial processing. The channel estimates can be derived from the reference signal and / or channel condition feedback transmitted by UE 250. Each spatial stream can then be provided to a different antenna 220 via a separate transmitter 218 TX. Each transmitter 218 TX can modulate an RF carrier with the corresponding spatial stream for transmission.

[0040] At UE 250, each receiver 254 RX receives signals through its respective antenna 252. Each receiver 254 RX recovers the information modulated onto the RF carrier and provides the information to the RX processor 256. The TX processor 268 and RX processor 256 implement Layer 1 functions associated with various signal processing functions. The RX processor 256 can perform spatial processing on this information to recover any spatial stream destined for UE 250. If multiple spatial streams are destined for UE 250, they can be combined by the RX processor 256 into a single OFDM symbol stream. The RX processor 256 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier are recovered and demodulated by determining the most probable signal constellation points transmitted by base station 210. These soft decisions can be based on channel estimates calculated by channel estimator 258. The soft decision is then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 210 on the physical channel. The data and control signals are then provided to controller / processor 259, which implements layer 3 and layer 2 functions.

[0041] Controller / processor 259 may be associated with memory 260, which stores program code and data. Memory 260 may be referred to as a computer-readable medium. In UL, controller / processor 259 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets from EPC 160. Controller / processor 259 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0042] Similar to the functions described in the DL transmission description of base station 210, controller / processor 259 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connectivity, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with upper-layer PDU transmission, error correction via ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs to TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority.

[0043] The TX processor 268 can use a reference signal transmitted from the base station 210 by the channel estimator 258 or a channel estimate derived from feedback to select an appropriate coding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 268 can be provided to different antennas 252 via individual transmitters 254TX. Each transmitter 254TX can modulate an RF carrier with the corresponding spatial stream for transmission. UL transmission is processed at the base station 210 in a manner similar to that described in conjunction with the receiver function at the UE 250. Each receiver 218RX receives a signal through its respective antenna 220. Each receiver 218RX recovers the information modulated onto the RF carrier and provides the information to the RX processor 270.

[0044] Controller / processor 275 may be associated with memory 276, which stores program code and data. Memory 276 may be referred to as a computer-readable medium. In the UL, controller / processor 275 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets from UE 250. IP packets from controller / processor 275 may be provided to EPC 160. Controller / processor 275 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0045] NR can refer to a radio configured to operate under a new air interface (e.g., different from an air interface based on Orthogonal Frequency Divisional Multiple Access (OFDMA)) or a fixed transport layer (e.g., different from Internet Protocol (IP)). NR can use OFDM with a cyclic prefix (CP) on both the uplink and downlink, and can include support for half-duplex operation using time division duplexing (TDD). NR may include mission-critical applications for enhanced mobile broadband (eMBB) services with wide bandwidths (e.g., exceeding 80 MHz), mmW for high carrier frequencies (e.g., 60 GHz), massive MTC (mMTC) for non-backward-compatible MTC technologies, and / or for ultra-reliable low-latency communication (URLLC) services.

[0046] It can support a single component carrier bandwidth of 100MHz. In one example, an NR resource block (RB) can span 12 subcarriers, each with a subcarrier bandwidth of 60 kHz for a duration of 0.125 ms or 15 kHz for a duration of 0.5 ms. Each radio frame can consist of 20 or 80 subframes (or NR slots) with a length of 10 ms. Each subframe can indicate the link direction (i.e., DL or UL) for data transmission, and the link direction of each subframe can be dynamically switched. Each subframe can include DL / UL data as well as DL / UL control data. UL and DL subframes for NR can be defined as follows: Figures 5 to 6 To describe in more detail.

[0047] NR RAN can include a central unit (CU) and a distributed unit (DU). NR BS (e.g., gNB, 5G Node B, Node B, transmission reception point (TRP), access point (AP)) can correspond to one or more BSs. NR cells can be configured as access cells (ACells) or data-only cells (DCells). For example, the RAN (e.g., a central unit or a distributed unit) can configure cells. A DCell may be a cell used for carrier aggregation or dual connectivity and may not be used for initial access, cell selection / reselection, or handover. In some cases, a DCell may not transmit a synchronization signal (SS); in other cases, it may transmit an SS. NR BSs can transmit downlink signals indicating the cell type to the UE. Based on the cell type indication, the UE can communicate with the NR BS. For example, the UE can determine which NR BS to consider for cell selection, access, handover, and / or measurement based on the indicated cell type.

[0048] Figure 3An example logical architecture of a distributed RAN 300 according to aspects of the present invention is illustrated. A 5G access node 306 may include an access node controller (ANC) 302. The ANC may be the central unit (CU) of the distributed RAN. The backhaul interface to the next-generation core network (NG-CN) 304 may terminate at the ANC. The backhaul interface to the adjacent next-generation access node (NG-AN) 310 may terminate at the ANC. The ANC may include one or more TRPs 308 (also referred to as BS, NR BS, Node B, 5G NB, AP, or some other terminology). As mentioned above, TRP can be used interchangeably with "cell".

[0049] TRP 308 can be a distributed unit (DU). A TRP can connect to one ANC (ANC302) or more ANCs (not shown). For example, for RAN sharing, radio as a service (RaaS), and service-specific ANC deployments, the TRP can connect to multiple ANCs. A TRP can include one or more antenna ports. A TRP can be configured to provide services to the UE individually (e.g., dynamically selected) or jointly (e.g., jointly transmitted).

[0050] The local architecture of the distributed RAN 300 can be used to illustrate the fronthaul definition. An architecture supporting fronthaul solutions across different deployment types can be defined. For example, the architecture can be based on transport network capabilities (e.g., bandwidth, latency, and / or jitter). The architecture can share features and / or components with LTE. Depending on the aspect, the NG-AN 310 can support dual connectivity with NR. The NG-AN can share a common fronthaul for LTE and NR.

[0051] This architecture enables cooperation between TRPs 308. For example, cooperation can be pre-defined within and / or across TRPs via ANC 302. Depending on various aspects, inter-TRP interfaces may not be required or exist.

[0052] Depending on various factors, the dynamic configuration of separate logical functions can exist within the architecture of the distributed RAN 300. PDCP, RLC, and MAC protocols can be adaptively placed at the ANC or TRP.

[0053] Figure 4An example physical architecture of a distributed RAN 400 according to aspects of the present invention is illustrated. A centralized core network unit (C-CU) 402 may host core network functions. The C-CU may be centrally deployed. C-CU functions may be offloaded (e.g., to an advanced wireless service (AWS)) to handle peak capacity. A centralized RAN unit (C-RU) 404 may host one or more ANC functions. Alternatively, the C-RU may host core network functions locally. The C-RU may have a distributed deployment. The C-RU may be located closer to the network edge. A distributed unit (DU) 406 may host one or more TRPs. The DU may be located at the network edge with radio frequency (RF) capabilities.

[0054] Figure 5 This is an example diagram 500 illustrating a DL-centered subframe. The DL-centered subframe may include a control portion 502. The control portion 502 may exist in the initial or beginning portion of the DL-centered subframe. The control portion 502 may include various scheduling and / or control information corresponding to the various portions of the DL-centered subframe. In some configurations, the control portion 502 may be a physical DL control channel (PDCCH), such as... Figure 5 As shown. A DL-centric subframe may also include a DL data portion 504. The DL data portion 504 may sometimes be referred to as the payload of the DL-centric subframe. The DL data portion 504 may include communication resources for transmitting DL data from a scheduling entity (e.g., a UE or BS) to a subordinate entity (e.g., a UE). In some configurations, the DL data portion 504 may be a physical DL shared channel (PDSCH).

[0055] The DL-centered subframe may also include a common UL section 506. The common UL section 506 may sometimes be referred to as a UL burst, a common UL burst, and / or various other suitable terms. The common UL section 506 may include feedback information corresponding to various other sections of the DL-centered subframe. For example, the common UL section 506 may include feedback information corresponding to the control section 502. Non-limiting examples of feedback information may include ACK signals, NACK signals, HARQ indicators, and / or various other suitable types of information. The common UL section 506 may include additional or alternative information, such as information related to the random access channel (RACH) procedure, scheduling request (SR), and various other suitable types of information.

[0056] like Figure 5 As shown, the end of the DL data portion 504 can be temporally separated from the start of the common UL portion 506. This temporal separation may sometimes be referred to as a gap, protection period, protection interval, and / or various other suitable terms. This separation provides time for the switch-over from DL communication (e.g., reception operation of a subordinate entity (e.g., UE)) to UL communication (e.g., transmission of a subordinate entity (e.g., UE)). Those skilled in the art will understand that the above is merely one example of a DL-centric subframe, and alternative structures with similar characteristics may exist without departing from the aspects described in this invention.

[0057] Figure 6 Figure 600 illustrates an example subframe centered on the UL. The UL-centered subframe may include a control section 602. The control section 602 may be present in the initial or beginning portion of the UL-centered subframe. Figure 6 The control section 602 in the above reference can be similar to the one mentioned above. Figure 5 The control portion 502 is described. The UL-centric subframe may also include a UL data portion 604. The UL data portion 604 may sometimes be referred to as the payload of the UL-centric subframe. The UL portion may refer to the communication resources used to transmit UL data from a subordinate entity (e.g., the UE) to a scheduling entity (e.g., the UE or the BS). In some configurations, the control portion 602 may be a physical DL control channel (PDCCH).

[0058] like Figure 6As shown, the end of control section 602 can be time-separated from the start of UL data section 604. This time separation may sometimes be referred to as a gap, protection cycle, protection interval, and / or various other suitable terms. This separation provides time for the switch from DL communication (e.g., receiving operations of a scheduling entity) to UL communication (e.g., transmissions of a scheduling entity). The UL-centric subframe may also include a common UL section 606. Figure 6 The public UL section 506 can be similar to the reference above. Figure 5 The common UL portion 506 is described. The common UL portion 606 may additionally or alternatively include information relating to the channel quality indicator (CQI), sounding reference signal (SRS), and various other suitable types of information. Those skilled in the art will understand that the foregoing is merely one example of a UL-centric subframe, and alternative structures with similar characteristics may exist without departing from the aspects described in this invention.

[0059] In some cases, two or more subordinate entities (e.g., UEs) can communicate with each other using sidelink signaling. Practical applications of such sidelink communication may include public safety, proximity services, UE-to-network relay, vehicle-to-vehicle (V2V) communication, Internet of Everything (IoE) communication, Internet of Things (IoT) communication, mission-critical meshes, and / or various other suitable applications. Typically, sidelink signaling can refer to a signal transmitted from one subordinate entity (e.g., UE1) to another subordinate entity (e.g., UE2) without relaying the communication through a scheduling entity (e.g., UE or BS), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, licensed spectrum can be used to transmit sidelink signals (unlike wireless LANs that typically use unlicensed spectrum).

[0060] Figure 7 Figure 700 illustrates the communication between base station 702 and UE 704. Base station 702 can establish component carriers 720-1, 720-2, ..., 720-J, ..., 720-K with UE 704. K is an integer greater than 1. Figure 7A reference carrier 790 is also shown, which in this example has a parameter set of 120 kHz (i.e., using a reference subcarrier spacing of 120 kHz). Each of the component carriers 720-1, 720-2, ..., 720-J, ..., 720-K can have a parameter set higher than that of the reference carrier 790 (e.g., 480 kHz, 960 kHz). In this example, the component carriers 720-1, 720-2, ..., 720-J, ..., 720-K have a parameter set of 480 kHz. In another example, the parameter sets of the different component carriers may be different.

[0061] Base station 702 allocates time slots 722 on component carriers 720-1, 720-2, ..., 720-J, ..., 720-K. Furthermore, base station 702 divides time slots 722 on each component carrier into consecutive time slot groups. For example, time slot 722 on component carrier 720-1 can be divided into time slot groups 730-1_1, 730-1_2, etc. In some configurations, each time slot group contains a configured number of consecutive time slots based on the subcarrier spacing of the component carriers. In this example, the subcarrier spacing is 480 kHz, and one time slot group contains 4 time slots. In another example, the subcarrier spacing is 960 kHz, and one time slot group contains 8 time slots.

[0062] In some configurations, base station 702 determines the boundaries of a time slot group based on the boundaries of a reference carrier's time slots. In this example, base station 702 may determine the time slot group boundaries based on reference carrier 790, which will be assigned reference time slot 792. For example, base station 702 aligns the start boundary of time slot group 730-1_1 with the start boundary of reference time slot 792, and also aligns the end boundary of time slot group 730-1_1 with the end boundary of the same reference time slot 792.

[0063] Similarly, base station 702 can divide time slots on other component carriers into time slot groups. In some configurations, time slot groups on each component carrier are allocated according to the same pattern. In this example, time slot groups 730-2_1... on component carrier 720-2, time slot group 730-J_1 on component carrier 720-J, and time slot group 730-K_1 on component carrier 720-K have the same start and end boundaries as time slot group 730-1_1 on component carrier 720-1, and are aligned with the same reference time slot 792 on reference carrier 790.

[0064] UE 704 can report its carrier aggregation (CA) capabilities, as well as blind detection and CCE monitoring capabilities, to base station 702. For example, UE 704 can report the maximum N in its supported CAs.cell CAP One component carrier. In the first technique, UE 704 also reports that it can perform a maximum P on a single component carrier. PDCCH slot_group,(X,Y),μ Blind detection and monitoring of maximum M on a single component carrier. PDCCH max,slot_group,(X,Y),μ A single component carrier has a set of parameters corresponding to μ in a time slot group (e.g., time slot group 730-1_1) corresponding to (X, Y). X represents the number of consecutive time slots in the time slot group, and Y represents the number of consecutive time slots the UE will monitor for the PDCCH within the time slot group. Specifically, the CCEs can be non-overlapping CCEs. μ is the subcarrier spacing of the component carriers, which is 15 × 2. μ The kHz value is determined. For example, when the subcarrier spacing is 480kHz, μ is 5. Each component carrier can have its own PDCCH monitoring configuration corresponding to (X,Y,μ).

[0065] In the second technology, UE 704 also reports that it can perform a maximum P PDCCH slot_group, X, μ Blind detection and monitoring of maximum M on a single component carrier. PDCCH max,slot_group, X, μ A CCE, wherein the single component carrier has a parameter set corresponding to μ in a time slot group (e.g., time slot group 730-1_1) that corresponds to X but is independent of Y.

[0066] Base station 702 can send N for scheduling monitoring to UE 704 cell DL Component carrier configuration. In the first case, N cell DL Not greater than N cell CAP Therefore, it is configured under the CA capability of UE 704. Using the first technique, UE 704 is limited to monitoring a maximum of M. PDCCH max,slot_group,(X,Y),μ A CCE is performed on a component carrier having a parameter set corresponding to μ in a time slot group corresponding to (X, Y) (i.e., the component carrier associated with (X, Y, μ)). Up to P PDCCH slot _group,(X,Y),μ Blind detection. In one example, N cell CAP Equal to K, and N cell DL Equal to J. Therefore, UE 704 can monitor up to M. PDCCH max,slot_group,(X,Y),μ × N cell DL,(X,Y),μA number of CCEs, and perform up to P operations on those CCEs associated with all component carriers (X, Y, μ) scheduled across a set of aligned time slot groups (e.g., time slot group 730-1_1, time slot group 730-2_1, ... and / or time slot group 730-J_1). PDCCH slot_group,(X,Y),μ × N cell DL,(X,Y),μ Blind detection. N cell DL ,(X,Y),μ It is N cell DL The number of component carriers associated with ((X, Y, μ) in the component carrier.

[0067] In the second case, N cell DL Greater than N cell CAP This means that the number of cells configured for PDCCH monitoring exceeds the UE's CA capability. In one example, N cell CAP Equal to J, and N cell DL Equal to K. Using the first technology, both base station 702 and UE 704 can determine that UE 704 can monitor up to M. PDCCH max,slot_group,(X,Y),μ × N cell DL,(X,Y),μ × N cell CAP / N cell DL Each CCE performs up to P operations across all component carriers associated with (X, Y, μ) scheduled in a set of aligned time slot groups (e.g., time slot group 730-1_1, time slot group 730-2_1, ... and / or time slot group 730-K_1). PDCCH slot_group,(X,Y),μ × N cell DL,(X,Y),μ × N cell CAP / N cell DL Blind detection. N cell CAP / N cell D It is used to adapt to N cell DL Greater than N cell CAP The reduction ratio.

[0068] In this example of the second scenario, and using the first technique, upon receiving the blind detection / CCE configuration from base station 702, UE 704 begins performing blind detection according to the blind detection configuration. Before performing the next set of blind detections on the next set of CCEs associated with (X, Y, μ), UE 704 determines whether to enforce the total blind detection limit, whether to monitor the total CCE limit, whether to enforce the per-component carrier blind detection limit, or whether to monitor the per-component carrier CCE limit. If performing the next set of blind detections on the next set of CCEs, all limits associated with (X, Y, μ) will be exceeded. If one of the limits will be exceeded, UE 704 discards one or more subsets of blind detections from the set until performing the remaining blind detections in that set does not result in exceeding any limit. UE 704 then performs the remaining blind detections (i.e., the blind detections that were not discarded), if any.

[0069] In the second scenario and using the second technology, base station 702 and UE 704 can determine that UE 704 can monitor up to M PDCCH max,slot_group,X,μ × N cell DL,X, μ × N cell CAP / N cell DL Each CCE performs multi-P operation across all component carriers associated with (X, Y, μ) scheduled in an aligned set of time slot groups (e.g., time slot group 730-1_1, time slot group 730-2_1, ... and / or time slot group 730-K_1). PDCCH slot_group,X,μ × N cell DL,X,μ × N cell CAP / N cell DL Blind detection. N cell CAP / N cell DL It is used to adapt to N cell DL Greater than N cell CAP The reduction ratio. N cell DL,X,μ It is in N cell DL The number of component carriers that are associated with (X, μ) but not with Y in a given component carrier.

[0070] In an illustrative example using the first technique, N cell CAP Equal to J, and N cellDL Equal to K. At a given point in time, UE 704 can be scheduled to perform the next set of blind detections on the component carrier 720-K associated with (4, 1, 5) (i.e., the value of (X, Y, μ)) in slot group 730-K_1. UE 704 can determine whether the total blind detections that UE 704 will perform after performing the next set of blind detections exceed P across all component carriers associated with (4, 1, 5) in the slot group aligned with slot group 730-K_1 (i.e., slot groups 730-1_1, ..., slot group 730-K_1). PDCCH slot_group,(4,1),5 ×N cell DL,(4,1),5 × J / K limit. If the limit is exceeded, UE 704 may discard one or more subsets of blind detections from the group until the total number of blind detections does not exceed the limit.

[0071] At this point in time, UE 704 can also determine whether the total number of CCEs monitored by UE 704 after performing the next set of blind detections exceeds M on all component carriers associated with (4, 1, 5) in the time slot group aligned with time slot group 730-K_1 (i.e., time slot group 730-1_1, ..., time slot group 730-K_1). PDCCH max,slot_group,(4,1),5 × N cell DL,(4,1),5 × J / K. If the limit is exceeded, UE 704 may discard one or more blind detection subsets from the group until the total CCE does not exceed the limit.

[0072] At this point in time, UE 704 can also determine whether the number of blind detections that UE 704 will perform after performing the next set of blind detections in slot group 730-K_1 on component carrier 720-K exceeds P. PDCCH slot_group,(4,1),5 The limit is set. If the limit is exceeded, UE 704 can discard one or more subsets of blind detections from the group until the number of blind detections does not exceed the limit.

[0073] UE 704 can also determine whether the number of CCEs monitored by UE 704 in slot group 730-K_1 on component carrier 720-K exceeds M after performing the next set of blind detections. PDCCH max,slot_group,(4,1),5 The limit is set. If the limit is exceeded, UE 704 can discard one or more blind detection subsets from the group until the number of CCEs does not exceed the limit.

[0074] In this example, when none of the limitations associated with (4, 1, 5) above are exceeded, UE 704 performs the remaining blind detection in slot group 730-K_1 on component carrier 720-K as scheduled by blind detection configuration.

[0075] Furthermore, base station 702 can send RRC configuration to UE 704 to configure search space 780 in each component carrier 720-1, 720-2, ..., 720-J, ..., 720-K. Specifically, the search space can be a type 1 common search space (CSS), a type 3 CSS, and a type 3 UE search space (UE-SS). The blind detection described above can be performed on CCE within the configured search space 780.

[0076] In some configurations, base station 702 can configure search space 780 at the same location within each time slot group. Taking component carrier 720-1 as an example, base station 702 can configure search space 780 at the same location within the first time slot of each time slot group 730-1_1, 730-1_2, etc.

[0077] Base station 702 can configure up to a predetermined number of DCI messages in the search space of each time slot group according to the subcarrier spacing of the component carriers. In some configurations, base station 702 can configure up to one DCI message in a time slot group of component carriers with subcarrier spacing of 120 kHz, 480 kHz, or 960 kHz.

[0078] Figure 8 This is a flowchart 800 of a method (process) for configuring blind detection. This method can be performed by a base station (e.g., base station 702). In operation 802, the base station allocates a time slot group comprising multiple consecutive time slots based on the operating subcarrier spacing. The start and end boundaries of the time slot group are each aligned with the boundaries of the time slots using the reference subcarrier spacing. In operation 804, the base station determines a first number of component carriers, which is the maximum number of component carriers configured for the UE in carrier aggregation. In operation 806, the base station determines a second number of component carriers already scheduled between the base station and the UE.

[0079] In operation 808, the base station determines the total blind detection limit for the time slot group to be performed by the UE and the total non-overlapping CCE limit monitored by the UE, both of which are associated with an operating subcarrier spacing based on a first number and a second number. In operation 810, the base station uses the operating subcarrier spacing used for the UE to perform blind detection to determine the blind detection limit for each component carrier. In operation 812, the base station uses the operating subcarrier spacing used for the UE to perform blind detection to determine the non-overlapping CCE limit for each component carrier.

[0080] In operation 814, the base station transmits a configuration that allocates P blind detections across M non-overlapping CCEs in a time slot group of a UE using an operating subcarrier interval. P is an integer not greater than the total blind detection limit. M is an integer not greater than the total number of non-overlapping CCEs. The P blind detections in the time slot group are allocated within the component carrier group based on the total blind detection limit and the blind detection limit for each component carrier using the operating subcarrier interval. The M non-overlapping CCEs in the time slot group are allocated among the component carrier groups based on the total non-overlapping CCE limit and the non-overlapping CCE limit for each component carrier using the operating subcarrier interval.

[0081] In some configurations, the start boundary of the time slot group is aligned with the start boundary of the reference time slot using a reference subcarrier spacing, and the end boundary of the time slot group is aligned with the end boundary of the reference time slot. In some configurations, the same time slot group is allocated on each component carrier of the component carrier group. In operation 816, the base station configures the same predetermined number of DCI messages in the time slot group on each component carrier in the component carrier group.

[0082] Figures 9(A) and 9(B) are flowcharts 900 of a method (process) for performing blind detection. This method can be performed by a UE (e.g., UE 704). In operation 902, the UE allocates a time slot group comprising multiple consecutive time slots based on the operating subcarrier interval. The start and end boundaries of the time slot group are each aligned with the boundaries of the time slots using the reference subcarrier interval. In operation 904, the UE receives a configuration that allocates blind detection on non-overlapping CCEs in the time slot group of a set of component carriers of the UE using the operating subcarrier interval.

[0083] In operation 906, the UE determines a first number of component carriers, which is the maximum number configured for the UE in carrier aggregation. In operation 908, the UE determines a second number of component carriers scheduled between the base station and the UE. In operation 910, the UE determines a blind detection limit for each component carrier using the operational subcarrier spacing used by the UE to perform blind detection. In operation 912, the UE determines a limit for non-overlapping CCEs for each component carrier using the operational subcarrier spacing in the time slot group to be monitored by the UE. In operation 914, the UE determines a total blind detection limit and a total non-overlapping CCE limit associated with the operational subcarrier spacing based on the first and second numbers.

[0084] In operation 916, the UE determines that it will transmit the same predetermined number of DCI messages on each component carrier of the component carrier group within the time slot group. In operation 918, the UE determines whether the total number of blind detections (including the next group of blind detections) to be performed by the UE on the component carrier group within the time slot group exceeds the limit of total blind detections associated with the operating subcarrier interval. When the total number of blind detections exceeds the limit of total blind detections, the UE proceeds to operation 928. When the total number of blind detections does not exceed the limit of total blind detections, in operation 920, the UE determines whether the total number of non-overlapping CCEs (including the next group of non-overlapping CCEs) to be monitored by the UE on the component carrier group exceeds the limit of total non-overlapping CCEs associated with the operating subcarrier interval. When the total number of non-overlapping CCEs exceeds the limit of total non-overlapping CCEs, the UE proceeds to operation 928.

[0085] When the total number of non-overlapping CCEs does not exceed the limit of total non-overlapping CCEs, in operation 922, the UE determines whether the number of blind detections performed by the UE on a given component carrier, including the next set of blind detections, will exceed the blind detection limit per component carrier using the operating subcarrier interval. When the number of blind detections exceeds the blind detection limit per component carrier, the UE proceeds to operation 928.

[0086] When the number of blind detections does not exceed the blind detection limit per component carrier, in operation 924, the UE determines whether the number of non-overlapping CCEs monitored by the UE on a given component carrier, including the next set of non-overlapping CCEs, exceeds the limit for non-overlapping CCEs per component carrier. When the number of non-overlapping CCEs exceeds the limit, the UE proceeds to operation 928.

[0087] When the number of non-overlapping CCEs does not exceed the limit, in operation 926, the UE performs the next set of blind detections on the next set of non-overlapping CCEs on a given component carrier of a set of component carriers, according to the configuration in the time slot group. Furthermore, after entering operation 928 as described above, the UE discards a subset of blind detections from the next set of blind detections. Additionally, operations 918, 920, 922, and 924 can be performed in any order. Figure 9(B) only shows an exemplary order of those operations performed.

[0088] In some configurations, the start boundary of the time slot group is aligned with the start boundary of the reference time slot using a reference subcarrier spacing, and the end boundary of the time slot group is aligned with the end boundary of the reference time slot. In some configurations, the same time slot group is allocated on each component carrier of the component carrier group. In some configurations, multiple blind detections are performed to decode the DCI message.

[0089] Figure 10Figure 1000 illustrates an example of a hardware embodiment for a device 1002 employing a processing system 1014. Device 1002 may be a base station. The processing system 1014 may be implemented using a bus architecture typically represented by a bus 1024.

[0095] Figure 11 This is an example diagram 1100 illustrating a hardware embodiment of a device 1102 employing a processing system 1114. Device 1102 may be a UE (User Equipment). The processing system 1114 may be implemented using a bus architecture typically represented by a bus 1124. The bus 1124 may include any number of interconnect buses and bridges, depending on the specific application and overall design constraints of the processing system 1114. The bus 1124 links various circuits together, including one or more processors and / or hardware components, represented by one or more processors 1104, receiving components 1164, transmitting components 1170, compensation components 1178, measurement components 1176, configuration components 1182, and computer-readable medium / memory 1106. The bus 1124 may also link various other circuits, such as timing sources, peripheral devices, voltage regulators, and power management circuits.
