Description
[0001] Cross-reference to related application(s)
[0002] This patent application claims the benefit of Greek application No. 20190100591, filed on December 27, 2019, entitled “TECHNIQUES FOR DOWNLINK AND UPLINK DATA DCI TRIGGERING FOR FULL DUPLEX UES IN A WIRELESS COMMUNICATION SYSTEM,” which is assigned to the assignee of this application and is hereby expressly incorporated herein by reference.
[0003] background
[0004] The present disclosure relates generally to communication systems, and more particularly to downlink control information (DCI) triggering for downlink and uplink data for full-duplex user equipment (UE) in Fifth Generation New Radio (5G NR).
[0005] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems 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), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and time division synchronous code division multiple access (TD-SCDMA).
[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)) and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements to 5G NR technology. These improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies.
[0007] As the demand for wireless communications continues to grow, it is desirable to improve the efficiency of wireless communication network technologies.
[0008] Overview
[0009] The following is a brief summary of one or more aspects to provide a basic understanding of such aspects. This summary is not an exhaustive overview of all conceivable aspects and is neither intended to identify key or critical elements of all aspects nor to define 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 is presented later.

[0011] An example implementation includes a wireless communication method, the method comprising: transmitting, by a UE, an RRC configuration message to a network entity indicating at least one of half-duplex capability or full-duplex capability of the UE; receiving, by the UE from the network entity, a first DCI format message for scheduling reception on a downlink channel; receiving, by the UE from the network entity, a second DCI format message for scheduling transmission on an uplink channel; and communicating between the UE and the network entity based on the first DCI format message and the second DCI format message. In one example, the first DCI format message is received separately from the second DCI format message.

[0026] Detailed description
[0027] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may 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 may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid overstating such concepts.
[0028] Several aspects of telecommunications systems will now be presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description 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 such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0029] As an example, an element, or any part of an element, or any combination of elements can be implemented as a "processing system" comprising one or more processors. Examples of processors include: a microprocessor, a microcontroller, a graphics processing unit (GPU), a central processing unit (CPU), an application processor, a digital signal processor (DSP), a reduced instruction set computing (RISC) processor, a system on a chip (SoC), a baseband processor, a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, a gating logic, a discrete hardware circuit, 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 can be broadly interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether it is described in software, firmware, middleware, microcode, hardware description language, or other terms.
[0030] Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, each function may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available medium that can be accessed by 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, a combination of the aforementioned types of computer-readable media, or any other medium that can be used to store instructions or data structures in the form of computer-executable code that can be accessed by a computer.
[0031] Figure 1 1 is a diagram illustrating an example of a wireless communication system and access network 100 configured for downlink and uplink data downlink control information (DCI) triggering for full-duplex user equipment (UE) in fifth generation new radio (5G NR). The wireless communication system (also known as a wireless wide area network (WWAN)) includes a base station 102, a UE 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)).
[0032] In certain aspects, the UE 104 may be configured to operate the communication component 198 and / or the configuration component 240 to transmit a radio resource control (RRC) configuration message to a network entity indicating the full-duplex capability of the UE; receive a DCI format message from the network entity, wherein the DCI format message enables concurrent transmission of an uplink channel and reception of a downlink channel by the UE on the same component carrier, wherein the concurrent transmission and reception include transmission and reception in at least one overlapping orthogonal frequency division multiplexing (OFDM) symbol; and communicate with the network entity based on the DCI format message.
[0033] In another aspect, the UE 104 can be configured to operate the communication component 198 and / or the configuration component 240 to transmit an RRC configuration message indicating at least one of half-duplex capability or full-duplex capability of the UE to a network entity; receive a first DCI format message from the network entity for scheduling reception on a downlink channel; receive a second DCI format message from the network entity for scheduling transmission on an uplink channel; and communicate with the network entity based on the first DCI format message and the second DCI format message. In one example, the first DCI format message is received separately from the second DCI format message.
[0034] Accordingly, in certain aspects, a network entity (e.g., base station 102) and / or another UE (such as UE 104) may be configured to operate communicating component 199 and / or configuring component 241 to transmit DCI format messages to UE 104. For example, communicating component 199 and / or configuring component 241 may transmit one or more DCI format messages to UE 104 and communicate with UE 104 based on the DCI format messages.
[0035] Base stations 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 femto cells, pico cells, and micro cells.
[0036] Base stations 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a backhaul link 132 (e.g., an S1 interface). Base stations 102 configured for 5G NR (collectively referred to as the Next Generation RAN (NG-RAN)) can interface with core network 190 via a backhaul link 184. Among other functions, base stations 102 can perform one or more of the following: delivery of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracking, RAN information management (RIM), paging, positioning, and delivery of alert messages. Base stations 102 may communicate with each other via backhaul links 134 (eg, an X2 interface), directly or indirectly (eg, through EPC 160 or core network 190). Backhaul links 132, 134, and 184 may be wired or wireless.
[0037] Base stations 102 can communicate wirelessly with UEs 104. Each base station 102 can provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102′ can have a coverage area 110′ that overlaps with the coverage area 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network can also include a home evolved Node B (eNB) (HeNB), which can provide service to a restricted group known as a closed subscriber group (CSG). The communication link 120 between the base station 102 and the UE 104 can include uplink (UL) (also known as reverse link) transmissions from the UE 104 to the base station 102 and / or downlink (DL) (also known as forward link) transmissions from the base station 102 to the UE 104. The communication link 120 can utilize multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. These communication links may be over one or more carriers. For each carrier allocated in the carrier aggregation for a total of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use 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). The component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell), and the secondary component carriers may be referred to as secondary cells (SCells).
[0038] Some UEs 104 may communicate with each other using device-to-device (D2D) communication links 158. The D2D communication links 158 may use DL / UL WWAN spectrum. The D2D communication links 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication may be accomplished through various wireless D2D communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.
[0039] The wireless communication system may further include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 in the 5 GHz unlicensed spectrum via a communication link 154. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) to determine whether the channel is available before communicating.
[0040] Small cell 102′ may operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102′ may employ NR and use the same 5 GHz unlicensed spectrum as used by Wi-Fi AP 150. Small cell 102′ employing NR in the unlicensed spectrum may improve access network coverage and / or increase access network capacity.
[0041] Whether a small cell 102′ or a large cell (e.g., a macro base station), base station 102 may include an eNB, a gNode B (gNB), or another type of base station. Some base stations, such as gNB 180, may operate in the traditional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near-mmW frequencies to communicate with UE 104. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 may be referred to as a mmW base station. Extremely high frequency (EHF) is a portion of the RF spectrum in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near-mmW extends down to 3 GHz frequencies with a wavelength of 100 mm. Super high frequency (SHF) bands extend between 3 GHz and 30 GHz and are also referred to as centimeter waves. Communications using mmW / near-mmW radio frequency bands (e.g., 3 GHz–300 GHz) have extremely high path loss and short range. The mmW base station 180 may utilize beamforming 182 with the UE 104 to compensate for the extremely high path loss and short range.
[0042] Base station 180 may transmit beamformed signals in one or more transmit directions 182′ to UE 104. UE 104 may receive beamformed signals from base station 180 in one or more receive directions 182″. UE 104 may also transmit beamformed signals to base station 180 in one or more transmit directions. Base station 180 may receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of base station 180 / UE 104. The transmit direction and receive direction of base station 180 may be the same or different. The transmit direction and receive direction of UE 104 may be the same or different.
[0043] 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 may be in communication with a Home Subscriber Server (HSS) 174. MME 162 is a control node that handles signaling between UE 104 and EPC 160. Generally speaking, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are delivered through Serving Gateway 166, which itself is connected to PDN Gateway 172. PDN Gateway 172 provides UE Internet Protocol (IP) address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Services 176. IP services 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), packet-switched (PS) streaming (PSS) services, and / or other IP services. BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. BM-SC 170 may serve as an entry point for content provider MBMS transmissions, may authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and may schedule MBMS transmissions. MBMS gateway 168 may distribute MBMS traffic to base stations 102 within a multicast broadcast single frequency network (MBSFN) area that broadcasts a specific service, and may be responsible for session management (start / stop) and collecting eMBMS-related charging information.
[0044] The core network 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a session management function (SMF) 194, and a user plane function (UPF) 195. The AMF 192 may be in communication with a unified data management (UDM) 196. The AMF 192 is a control node that handles signaling between the UE 104 and the core network 190. Generally speaking, the AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are passed through the UPF 195. The UPF 195 provides UE IP address allocation and other functions. The UPF 195 is connected to the IP services 197. The IP services 197 may include the Internet, an intranet, an IP multimedia subsystem (IMS), PS streaming services, and / or other IP services.
[0045] A base station may also be referred to as a gNB, a NodeB, an evolved NodeB (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit reception point (TRP), or some other suitable terminology. Base station 102 provides an access point for UE 104 to EPC 160 or core network 190. Examples of UE 104 include a cellular phone, a smartphone, a Session Initiation Protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., an MP3 player), a camera, a game console, a tablet device, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similarly functional device. Some UEs 104 may be referred to as IoT devices (e.g., a parking meter, a gas pump, an oven, a vehicle, a heart monitor, etc.). UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.
[0046] Figures 2A-2D Included are diagrams of example frame structures and resources that may be utilized in communications between base station 102, UE 104, and / or secondary UE (or sidelink UE) 110 as described in the present disclosure. Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G / NR frame structure. Figure 2B is a diagram 230 illustrating an example of DL channels within a 5G / NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G / NR frame structure. Figure 2D 280 is a diagram illustrating an example of UL channels within a 5G / NR subframe. The 5G / NR frame structure can be frequency division duplex (FDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL; or it can be time division duplex (TDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL. Figure 2A and 2CIn the example provided, 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 34 (mostly UL), where D is DL, U is UL, and X is for flexible use between DL / UL. Although subframes 3 and 4 are shown as having slot formats 34 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 full DL and full UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible codewords. The UE is configured with the slot format (dynamically configured through DL control information (DCI) or semi-statically / statically configured through radio resource control (RRC) signaling) via the received slot format indicator (SFI). Note that the following description also applies to the 5G / NR frame structure for TDD.
[0047] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 equally sized subframes (1ms). Each subframe may include one or more time slots. A subframe may also include mini-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. The symbols on the DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. The symbols on the UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also known as single carrier frequency division multiple access (SC-FDMA) symbols) (for power-limited 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 5 allow 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different parameter designs 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Accordingly, for slot configuration 0 and parameter design μ, there are 14 symbols per slot and 2 per subframe. μ The subcarrier spacing and symbol length / duration vary depending on the parameter design. The subcarrier spacing can be equal to 2 μ *15kHz, where μ is parameter design 0 to 5. Thus, parameter design μ=0 has a subcarrier spacing of 15kHz, while parameter design μ=5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figures 2A-2D An example is provided for slot configuration 0 with 14 symbols per slot and parameter design μ = 0 with 1 slot per subframe. The subcarrier spacing is 15 kHz and the symbol duration is approximately 66.7 μs.
[0048] A resource grid can be used to represent the frame structure. Each slot includes a resource block (RB) (also called a physical RB (PRB)) that extends over 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.
[0049] like Figure 2A As illustrated in
[15] , some REs carry reference (pilot) signals (RS) for the UE. The RSs may include a demodulation RS (DM-RS) (indicated as Rx for one specific configuration, where 100x is the port number, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RSs may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).
[0050] Figure 2B An example of various DL channels within a subframe of a frame is illustrated. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE includes 9 RE groups (REGs), and each REG includes 4 consecutive REs in an OFDM symbol. The primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a 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 within symbol 4 of a particular subframe of a 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. 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 through the PBCH (such as System Information Blocks (SIBs)), and paging messages.
[0051] As in Figure 2CAs illustrated in FIG, some REs carry DM-RSs for channel estimation at the base station (indicated as R for one specific configuration, but other DM-RS configurations are possible). The UE may transmit DM-RSs for the physical uplink control channel (PUCCH) and DM-RSs for the physical uplink shared channel (PUSCH). The PUSCH DM-RSs may be transmitted in the first one or the first two symbols of the PUSCH. The PUCCH DM-RSs may be transmitted in different configurations depending on whether a short PUCCH or a long PUCCH is transmitted and on the specific PUCCH format used. Although not shown, the UE may transmit a sounding reference signal (SRS). The SRS may be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.
[0052] Figure 2D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at the position indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), and hybrid automatic repeat request (HARQ) ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.
[0053] Figure 33 is a block diagram of a base station 310 and a UE 350 in communication in an access network, where base station 310 may be an example implementation of base station 102, and where UE 350 may be an example implementation of UE 104. In the DL, IP packets from EPC 160 may be provided to controller / processor 375. Controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with delivery of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0054] The transmit (TX) processor 316 and the 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) encoding / decoding of the transport channel, interleaving, rate matching, mapping onto the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The TX processor 316 handles 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 coded 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 domain, and then combined together 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 a channel estimator 374 may be used to determine the coding and modulation schemes and for spatial processing. The channel estimates may be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX may modulate an RF carrier with a corresponding spatial stream for transmission.
[0055] At the UE 350, each receiver 354RX receives a signal via its corresponding antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, as well as the reference signal, are recovered and demodulated by determining the signal constellation point most likely transmitted by the base station 310. These soft decisions may be based on channel estimates calculated by the channel estimator 358. These soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted on the physical channel by the base station 310. These data and control signals are then provided to the controller / processor 359, which implements layer 3 and layer 2 functionality.
[0056] The controller / processor 359 may be associated with a memory 360 that stores program codes 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 operations.
[0057] Similar to the functionality described in conjunction with DL transmissions performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with delivery of upper layer PDUs, error correction through 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 through HARQ, priority handling, and logical channel prioritization.
[0058] Channel estimates derived by a channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by a TX processor 368 to select the appropriate coding and modulation scheme, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a corresponding spatial stream for transmission.
[0059] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318RX receives a signal through its respective antenna 320. Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to an RX processor 370.
[0060] The controller / processor 375 may be associated with a memory 376 that stores program codes 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. The 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 operations.
[0061] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform operations related to Figure 1 The communication component 198 combines various aspects.
[0062] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform operations related to Figure 1 The communication component 199 combines various aspects.
[0063] refer to Figure 4-10 The described features generally relate to downlink control information (DCI) triggering for downlink and uplink data for full-duplex UEs in fifth generation new radio (5G NR). For example, two separate DCI format messages are currently utilized when scheduling information for uplink and downlink channels.
[0064] Currently, DCI format 1_1 schedules information for downlink channels. In one example, DCI format 1_1 includes fields for the following: frequency domain resource assignment (FDRA), frequency domain assignment type (type 0 / 1), time domain resource allocation (TDRA), precoding resource block group (PRG) bundling indicator, VRB-2-PRB mapping indicator, carrier indicator, rate matching indicator, ZPCSI-RS trigger, TCI-state indication, bandwidth part (BWP) indicator, MCS, NDI, redundancy version (RV) per TB, HARQ process number, antenna port, PUCCH resource indicator, transmit power control (TPC) command for scheduled PUCCH, SRS request, code block group (CBG) transmission information, and DMRS sequence initialization.
[0065] Currently, DCI format 0_1 schedules information for uplink channels. In one example, DCI format 0_1 includes fields for the following: carrier indicator, bandwidth fraction indicator, frequency domain resource assignment, time domain resource assignment, frequency hopping flag, modulation and coding scheme, new data indicator, redundancy version, HARQ process number, TPC command for scheduled PUSCH, UL / SUL indicator, SRS resource indicator, precoding information and number of layers, antenna port, SRS request, CSI request, CBG transmission information (CBGTI), PTRS-DMRS association, β_offset indicator, DMRS sequence initialization, and UL-SCH indicator.
[0066] Therefore, DCI format 1_1 and DCI format 0_1 share several fields, such as but not limited to antenna port and SRS request fields.
[0067] The present disclosure generally relates to the current problem of downlink and uplink data DCI triggering for full-duplex UEs. For example, in one aspect, the present disclosure includes methods, apparatus, and non-transitory computer-readable media for wireless communications, which are used to: transmit, by a UE, a radio resource control (RRC) configuration message indicating the full-duplex capability of the UE to a network entity; receive, by the UE, a DCI format message from the network entity, wherein the DCI format message enables concurrent transmission of an uplink channel and reception of a downlink channel by the UE on the same component carrier, wherein the concurrent transmission and reception include transmission and reception in at least one overlapping orthogonal frequency division multiplexing (OFDM) symbol; and communicate between the UE and the network entity based on the DCI format message. In another aspect, for example, the present disclosure includes methods, apparatus, and non-transitory computer-readable media for wireless communications, configured to: transmit, by a UE, an RRC configuration message indicating at least one of half-duplex capability or full-duplex capability of the UE to a network entity; receive, by the UE, from the network entity, a first DCI format message for scheduling reception on a downlink channel; receive, by the UE, from the network entity, a second DCI format message for scheduling transmission on an uplink channel; and communicate between the UE and the network entity based on the first DCI format message and the second DCI format message. In one example, the first DCI format message is received separately from the second DCI format message.
[0068] Figure 4FIG4 is a diagram illustrating a full-duplex communication mode. For example, scenario 410 depicts a full-duplex base station and half-duplex UEs 1 and 2. In scenario 410, a full-duplex first gNB can transmit to UE 1 on a downlink channel and receive from UE 2 on an uplink channel. However, UE 2 may cause interference on UE 1 due to its uplink transmission to the first gNB. Furthermore, a second gNB may cause interference on the first gNB due to its communications with both UE 1 and UE 2. Additionally, the first gNB may cause self-interference from both downlink and uplink communications.
[0069] In one aspect, scenario 420 depicts a full-duplex gNB and a full-duplex UE 1. In scenario 420, UE 1 experiences self-interference from full-duplex uplink and downlink communications with the first gNB, from UE 2 receiving downlink communications from a second gNB, and from downlink communications from the second gNB.
[0070] In one aspect, scenario 430 depicts a full-duplex UE 1 communicating simultaneously with a first gNB in uplink and a second gNB in downlink using multiple TRPs. For example, because UE 1 is the only entity configured in full-duplex mode, UE 1 experiences self-interference due to both uplink and downlink communications with the first gNB and the second gNB.
[0071] Figure 5 5 is a diagram illustrating a half-duplex communication mode. For example, scenario 510 depicts a transmit receive point 1 (TRP1) configured in full-duplex mode with a half-duplexed UE. Accordingly, diagram 520 depicts a subframe / timeslot decomposition for a full-duplex TRP1 and a half-duplex UE. In this example, entities can participate in time-flexible downlink and uplink operations across time slots and across UEs. That is, simultaneous PDSCH and PUSCH grants for the same subframe / time slot for different UEs can be configured. The UE can change the uplink transmit and / or downlink receive bandwidth portion between time slots with zero latency. The UE can transmit a sounding reference signal (SRS) using full reciprocity (e.g., full duplex) to cover the entire downlink bandwidth portion and partial reciprocity (e.g., half duplex) to cover a portion of the downlink bandwidth. In this example, the dotted lines of diagram 520 depict a subframe / timeslot decomposition for a full-duplex TRP1 and a half-duplex UE.
[0072] Figure 66 is a diagram illustrating a full-duplex communication mode. For example, scenario 610 depicts TRP1 configured in full-duplex mode with a full-duplexed UE and a half-duplexed UE. Accordingly, diagram 620 depicts a subframe / time slot decomposition of a full-duplex TRP1 and a full-duplex UE. In this example, entities can participate in downlink and uplink operations that are flexible in time across time slots and across UEs. That is, simultaneous PDSCH and PUSCH grants for the same subframe / time slot for different UEs can be configured. A full-duplex UE can be configured for uplink and downlink grants. The UE can change the uplink transmission and / or downlink reception bandwidth portion between each time slot with zero waiting time. The UE can transmit SRS using full reciprocity (e.g., full duplex) for covering the entire downlink bandwidth portion and partial reciprocity (e.g., half duplex) for covering a portion of the downlink bandwidth. In this example, the dotted line of diagram 620 depicts the subframe / timeslot breakdown for a full-duplex TRP1 and a half-duplex UE.
[0073] Figure 7 700 is a flow chart of a method of wireless communication. The method may be performed by a UE (e.g., UE 104; apparatus 350; controller / processor 359 (which may include memory 360), processor(s) 1012 (which may include memory 1016, modem 1040), which may be the entire UE 104 or components of the UE 104 (such as TX processor 368, RX processor 356, and / or transceiver 1002)) in conjunction with communication component 198 / configuration component 240.
[0074] At 702, method 700 includes transmitting, by the UE, an RRC configuration message indicating full-duplex capability of the UE to a network entity. In one aspect, the UE 104 and / or the communication component 198 / configuration component 240 may be configured to transmit, to the network entity, an RRC configuration message indicating full-duplex capability of the UE. As such, the UE 104 and / or the communication component 198 / configuration component 240 (e.g., in conjunction with the controller / processor 359 (which may include memory 360), the processor(s) 1012 (which may include memory 1016, the modem 1040, the TX processor 368, and the transceiver 1002)) may define means for transmitting, by the UE, an RRC configuration message indicating full-duplex capability of the UE to the network entity.
[0075] At 704, method 700 includes receiving, by the UE from a network entity, a DCI format message, wherein the DCI format message enables a format for concurrent transmission of an uplink channel and reception of a downlink channel by the UE on the same component carrier, wherein the concurrent transmission and reception include transmission and reception in at least one overlapping OFDM symbol. In an aspect, UE 104 and / or communication component 198 / configuration component 240 may be configured to receive, from the network entity, a DCI format message, wherein the DCI format message enables a format for concurrent transmission of an uplink channel and reception of a downlink channel by the UE on the same component carrier, wherein the concurrent transmission and reception include transmission and reception in at least one overlapping OFDM symbol. As such, the UE 104 and / or the communication component 198 / configuration component 240 (e.g., in conjunction with the controller / processor 359 (which may include the memory 360), the processor(s) 1012 (which may include the memory 1016, the modem 1040, the RX processor 356, and the transceiver 1002)) may define means for receiving, by the UE, a DCI format message from a network entity, wherein the DCI format message is formatted to enable concurrent transmission of an uplink channel and reception of a downlink channel by the UE on the same component carrier, wherein the concurrent transmission and reception include transmission and reception in at least one overlapping OFDM symbol. For example, the transmission and reception may correspond to a partial overlap of the OFDM symbols.
[0076] In the example of method 700, the DCI format message implements a joint triggering of concurrent transmission on an uplink channel and reception on a downlink channel by the UE. For example, the uplink channel corresponds to a physical uplink shared channel (PUSCH) SRS or a channel for transmission of SRS. In addition, the downlink channel corresponds to a CSI-RS, a physical downlink shared channel (PDSCH), a positioning reference signal (PRS), and a tracking reference signal (TRS). In addition, the DCI format message is configured to schedule at least one of a downlink channel and an uplink channel that overlap in at least one OFDM symbol, the downlink channel including a group of OFDM symbols, and the uplink channel including a group of OFDM symbols.
[0077] In an example of method 700, the DCI format message includes one or more merged fields that are common to both transmission on the uplink channel and reception on the downlink channel. For example, the uplink channel and the downlink channel overlap on the same number of OFDM symbols of the shared carrier. The one or more merged fields include time domain resource allocation (TDRA) for both the downlink channel and the uplink channel. In one example, the TDRA includes a time domain resource allocation starting at a symbol offset after the reception of the DCI format message. In addition, the one or more merged fields include a first frequency domain resource assignment (FDRA) for the downlink channel and a second FDRA for the uplink channel, wherein the first FDRA occupies a greater number of bits than the second FDRA.
[0078] In an example of method 700, the one or more merged fields include a joint transmission configuration indication (TCI) indication. For example, each of the one or more TCI states has a quasi-co-location (QCL) for a downlink channel and a QCL for an uplink channel. Each of the one or more TCI states has a QCL for a downlink channel and an SRS resource indicator (SRI) for an uplink channel.
[0079] In an example of method 700, one or more merged fields include a mapping of virtual resource blocks (VRBs) to physical resource blocks (PRBs) associated with downlink and uplink channels.
[0080] In an example of method 700, the one or more combined fields include a DMRS sequence initialization associated with a first demodulation reference signal (DMRS) for a downlink channel and a second DMRS for an uplink channel.
[0081] In an example of method 700, the one or more merged fields include a joint DMRS port indication table identifying a port for each of the downlink channel and the uplink channel.
[0082] In an example of method 700, the one or more combined fields include a joint field that triggers both SRS resources and CSI RS resources on the same one or more OFDM symbols.
[0083] In an example of method 700, receiving, by the UE, a DCI format message from a network entity further includes receiving, by the UE, a first part of the DCI format message from the network entity, the first part including information indicating a location of a second part of the DCI format message, wherein the second part of the DCI format message includes remaining information not included in the first part of the DCI format message; and receiving, by the UE, the second part of the DCI format message from the network entity based on the first part of the DCI format message.
[0084] For example, the first part of the DCI format message includes one or more common fields for downlink channel and uplink channel allocation. In addition, the one or more common fields include at least one of the following: time domain resource allocation (TDRA), frequency domain resource assignment (FDRA), SRS request and CSI request.
[0085] For example, the first portion of the DCI format message further includes one or more downlink-related parameters for scheduling downlink transmissions, and a pointer to scheduling information for the remaining information in the second portion of the DCI format. Furthermore, method 700 may include determining that the scheduling information is within a scheduled PDSCH; and scheduling the PUSCH after the offset number of symbols based on the determination that the scheduling information is within the scheduled PDSCH.
[0086] At 706, method 700 includes communicating between the UE and a network entity based on the DCI format message. In one aspect, UE 104 and / or communication component 198 / configuration component 240 can be configured to transmit data to one or more second UEs using the one or more reserved transmission resources. As such, UE 104 and / or communication component 198 / configuration component 240 (e.g., in conjunction with controller / processor 359 (which may include memory 360), processor(s) 1012 (which may include memory 1016, modem 1040, RX processor 356, and transceiver 1002)) can define means for transmitting data by a first UE to one or more second UEs using the one or more reserved transmission resources.
[0087] Figure 8 800 is a flow chart of a method of wireless communication. The method may be performed by a UE (e.g., UE 104; apparatus 350; controller / processor 359 (which may include memory 360), processor(s) 1012 (which may include memory 1016, modem 1040), which may be the entire UE 104 or components of the UE 104 (such as TX processor 368, RX processor 356, and / or transceiver 1002)) in conjunction with communication component 198 / configuration component 240.
[0088] At 802, method 800 includes transmitting, by the UE, an RRC configuration message indicating full-duplex capability of the UE to a network entity. In one aspect, the UE 104 and / or the communication component 198 / configuration component 240 may be configured to transmit, by the UE, an RRC configuration message indicating full-duplex capability of the UE to the network entity. As such, the UE 104 and / or the communication component 198 / configuration component 240 (e.g., in conjunction with the controller / processor 359 (which may include memory 360), the processor(s) 1012 (which may include memory 1016, the modem 1040, the TX processor 368, and the transceiver 1002)) may define means for transmitting, by the UE, an RRC configuration message indicating full-duplex capability of the UE to the network entity.
[0089] At 804, method 800 includes receiving, by the UE, a self-contained DCI format message from a network entity, the self-contained DCI format message including information associated with a first portion of the self-contained DCI. In one aspect, UE 104 and / or communication component 198 / configuration component 240 may be configured to receive, by the UE, a self-contained DCI format message from the network entity, the self-contained DCI format message including information associated with the first portion of the self-contained DCI. As such, UE 104 and / or communication component 198 / configuration component 240 (e.g., in conjunction with controller / processor 359 (which may include memory 360), processor(s) 1012 (which may include memory 1016, modem 1040, TX processor 368, and transceiver 1002)) may define means for receiving, by the UE, a self-contained DCI format message from the network entity, the self-contained DCI format message including information associated with the first portion of the self-contained DCI. In one aspect, the self-contained DCI format message will be able to trigger downlink PDSCH and PUSCH for a full-duplex UE, such as UE 104. For example, the first portion of the self-contained DCI format message further includes one or more downlink-related parameters for scheduling downlink transmissions, and a pointer to scheduling information that points to the remaining information in the second portion of the self-contained DCI.
[0090] At 806, method 800 includes communicating between the UE and the network entity based on the DCI format message. In one aspect, the UE 104 and / or the communication component 198 / configuration component 240 can be configured to communicate between the UE and the network entity based on the DCI format message. As such, the UE 104 and / or the communication component 198 / configuration component 240 (e.g., in conjunction with the controller / processor 359 (which can include memory 360), the processor(s) 1012 (which can include memory 1016, the modem 1040, the TX processor 368, and the transceiver 1002)) can define means for communicating between the UE and the network entity based on the DCI format message.
[0091] In an example of method 800, UE 104 and / or communication component 198 / configuration component 240 may be configured to determine that scheduling information is within the scheduled PDSCH; and schedule the PUSCH after the offset number of symbols based on the determination that the scheduling information is within the scheduled PDSCH.
[0092] In the example of method 800, the offset number of symbols corresponds to a number of symbols after the last symbol carrying control information for the PUSCH.
[0093] In the example of method 800 , the first portion of the self-contained DCI format message includes one or more downlink-related parameters but does not include uplink-related parameters.

[0095] At 902, method 900 includes transmitting, by the UE, an RRC configuration message to a network entity indicating at least one of half-duplex capability or full-duplex capability of the UE. In one aspect, the UE 104 and / or the communication component 198 / configuration component 240 may be configured to transmit, to the network entity, an RRC configuration message indicating at least one of half-duplex capability or full-duplex capability of the UE. As such, the UE 104 and / or the communication component 198 / configuration component 240 (e.g., in conjunction with the controller / processor 359 (which may include memory 360), the processor(s) 1012 (which may include memory 1016, the modem 1040, the TX processor 368, and the transceiver 1002)) may define means for transmitting, by the UE, an RRC configuration message to the network entity indicating at least one of half-duplex capability or full-duplex capability of the UE.
[0096] At 904, method 900 includes receiving, by the UE, a first DCI format message for scheduling reception on a downlink channel from a network entity. In one aspect, the UE 104 and / or the communication component 198 / configuration component 240 may be configured to receive, from the network entity, a first DCI format message for scheduling reception on a downlink channel. As such, the UE 104 and / or the communication component 198 / configuration component 240 (e.g., in conjunction with the controller / processor 359 (which may include memory 360), the processor(s) 1012 (which may include memory 1016, the modem 1040, the TX processor 368, and the transceiver 1002)) may define means for receiving, by the UE, from the network entity, a first DCI format message for scheduling reception on a downlink channel.
[0097] At 906, method 900 includes receiving, by the UE, a second DCI format message for scheduling transmissions on an uplink channel from a network entity. In one example, the first DCI format message is received separately from the second DCI format message. In one aspect, the UE 104 and / or the communication component 198 / configuration component 240 may be configured to receive, from the network entity, a second DCI format message for scheduling transmissions on an uplink channel. In one example, the first DCI format message is received separately from the second DCI format message. As such, the UE 104 and / or the communication component 198 / configuration component 240 (e.g., in conjunction with the controller / processor 359 (which may include memory 360), the processor(s) 1012 (which may include memory 1016, the modem 1040, the TX processor 368, and the transceiver 1002)) may define means for receiving, by the UE, a second DCI format message for scheduling transmissions on an uplink channel from the network entity. In one example, the first DCI format message is received separately from the second DCI format message.
[0098] At 908, method 900 includes communicating between the UE and the network entity based on the first DCI format message and the second DCI format message. In one aspect, the UE 104 and / or the communication component 198 / configuration component 240 can be configured to communicate with the network entity based on the first DCI format message and the second DCI format message.

[0099] In the example of method 900, the scheduling of reception on the downlink channel and the scheduling of transmission on the uplink channel overlap in at least one OFDM symbol.For example, each of the first DCI format message and the second DCI format message includes an indicator for identifying full duplex mode or half duplex mode.
[0100] In an example of method 900, the second DCI format message is configured to be received within a threshold time period from receipt of the first DCI format message.
