[0028] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for supporting bandwidth part (BWP) pairs with non-aligned center frequencies for full-duplex operation.

[0029] Full-duplex communications allow simultaneous transmissions between nodes (eg, user equipment (UE) and a network entity). Half-duplex communications flow in one direction at a time.

[0030] In current systems, time division duplex (TDD) or frequency division duplex (FDD) is used to allocate resources for bidirectional communication. In TDD or FDD, communication using a single frequency channel is possible in only one direction at any given time. Therefore, FDD and TDD systems achieve full-duplex functionality by using multiple frequency channels (as in the case of FDD) or by dividing the two communication directions according to allocated time slots (as in the case of TDD).

[0031] In the communication between a network entity (e.g., a base station) and a UE, different resources (i.e., different frequencies (e.g., FDD) or time resources (e.g., TDD)) are used for uplink and downlink to achieve simultaneous transmission and reception. An FDD system has separate uplink and downlink frequency bands, while a TDD system utilizes the same bandwidth but allocates different time slots for uplink and downlink. Compared with an FDD system, a TDD system has greater flexibility in uplink and downlink. For example, a TDD system can also more easily adapt the ratio between uplink and downlink traffic, and they do not require paired spectrum for uplink and downlink.

[0032] In current TDD systems (or half-duplex systems), network entities may configure downlink bandwidth parts (BWPs) and uplink BWPs with aligned center frequencies. Each BWP may include a subset of the total cell bandwidth of a cell. For example, in the case of a TDD system, a BWP pair (e.g., a downlink BWP and an uplink BWP with the same BWP ID) must have the same center frequency (e.g., an overlap of a downlink BWP and an uplink BWP). This overlap prevents the use of a BWP pair for full-duplex operation.

[0033] The techniques proposed herein support BWP pairs with non-aligned center frequencies for full-duplex operation. For example, a UE may indicate the capability of non-aligned center frequencies on a downlink BWP and an uplink BWP. A network entity may configure non-aligned downlink BWP and uplink BWP for a UE for sub-band / frequency division multiplexing (FDM) full-duplex operation. The downlink BWP and uplink BWP may be separated from each other or partially overlapped. The proposed techniques may result in reduced latency (e.g., because a downlink signal may be received in an uplink timeslot during full-duplex operation) and better resource utilization.

[0034] Introduction to wireless communication networks

[0035] The techniques and methods described herein can be used in various wireless communication networks. Although various aspects may be described herein using terms commonly associated with 3G, 4G and / or 5G wireless technologies, various aspects of the present disclosure may also be applicable to other communication systems and standards not explicitly mentioned herein.

[0036] Figure 1 An example of a wireless communication network 100 is depicted in which various aspects described herein may be implemented.

[0037] In general, the wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). A network entity is typically a communication device and / or a communication function performed by a communication device (e.g., user equipment (UE), base station (BS), component of a BS, server, etc.). For example, various functions of a network and various devices associated with and interacting with the network may be considered network entities. In addition, the wireless communication network 100 includes ground aspects, such as ground-based network entities (e.g., BS 102), and non-ground aspects, such as satellites 140 and aircraft 145, which may include airborne network entities (e.g., one or more BSs) that can communicate with other network elements (e.g., ground BSs) and UEs.

[0038] In the depicted example, the wireless communication network 100 includes a BS 102, a UE 104, and one or more core networks (such as an evolved packet core (EPC) 160 and a 5G core (5GC) network 190) that interoperate to provide communication services over various communication links (including wired and wireless links).

[0039] Figure 1 Various example UEs 104 are depicted, which may more generally include: a cellular phone, a smart phone, 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, a camera, a game console, a tablet computer, 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, an Internet of Things (IoT) device, an Always-On (AON) device, an edge processing device, or other similar devices. UE 104 may also be more generally referred to as a mobile device, a wireless device, a wireless communication device, a station, a mobile station, a subscriber station, a mobile subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, and others.

[0040] BS 102 wirelessly communicates with (e.g., transmits signals to or receives signals from) UE 104 via communication link 120. Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also referred to as a reverse link) transmissions from UE 104 to BS 102 and / or downlink (DL) (also referred to as a forward link) transmissions from BS 102 to UE 104. In various aspects, communication link 120 may employ multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity.

[0041] BS 102 may generally include: NodeB, enhanced NodeB (eNB), next generation enhanced NodeB (ng-eNB), next generation NodeB (gNB or gNodeB), access point, transceiver base station, radio BS, radio transceiver, transceiver function, transmission and reception point, and / or other. Each of BS 102 may provide communication coverage for a corresponding geographic coverage area 110, which may sometimes be referred to as a cell, and may overlap in some cases (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, a BS may provide communication coverage for a macro cell (covering a relatively large geographic area), a pico cell (covering a relatively small geographic area, such as a stadium), a femto cell (relatively small geographic area (e.g., a home)), and / or other types of cells.

[0042] Although BS102 is depicted as a single communication device in various aspects, BS102 can be implemented in various configurations. For example, one or more components of BS102 may be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC) or a non-real-time (non-RT) RIC, to name a few examples. In another example, various aspects of BS102 may be virtualized. More generally, a BS (e.g., BS102) may include components located at a single physical location or components located at various physical locations. In an example in which BS102 includes components located at various physical locations, various components may each perform each function so that various components together achieve functions similar to those of BS102 located at a single physical location. In some aspects, a BS102 including components located at various physical locations may be referred to as a decomposed radio access network (RAN) architecture, such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture. Figure 2 An example decomposed BS architecture is depicted and described.

[0043] Different BSs 102 within the wireless communication network 100 may also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 via a first backhaul link 132 (e.g., an S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) may interface with the 5GC 190 via a second backhaul link 184. The BSs 102 may communicate with each other directly or indirectly (e.g., via the EPC 160 or the 5GC 190) over a third backhaul link 134 (e.g., an X2 interface), which may be wired or wireless.

[0044] The wireless communication network 100 may subdivide the electromagnetic spectrum into various categories, frequency bands, channels, or other characteristics. In some aspects, the subdivision is provided based on wavelength and frequency, where frequency may also be referred to as a carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 600 MHz-6 GHz, which is often (interchangeably) referred to as "below 6 GHz". Similarly, 3GPP currently defines frequency range 2 (FR2) as including 26 GHz-41 GHz, which is sometimes (interchangeably) referred to as "millimeter wave" ("mmW" or "mmWave"). A BS (e.g., a mmWave BS such as BS 180) configured to communicate using mmWave / near mmWave radio bands may utilize beamforming (e.g., 182) with a UE (e.g., 104) to improve path loss and distance.

[0045] The communication link 120 between the BS 102 and, for example, the UE 104 may be through one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, and / or other MHz) and may be aggregated in various aspects. The 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 for DL ​​compared to UL).

[0046] Communications using higher frequency bands may have higher path loss and shorter range than communications at lower frequencies. Figure 1180) may utilize beamforming 182 with UE 104 to improve path loss and distance. For example, BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels and / or antenna arrays, to facilitate beamforming. In some cases, BS 180 may send beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamformed signals from BS 180 in one or more receive directions 182". UE 104 may also send beamformed signals to BS 180 in one or more transmit directions 182". BS 180 may also receive beamformed signals from UE 104 in one or more receive directions 182'. BS 180 and UE 104 may then perform beam training to determine the best receive direction and transmit direction for each of BS 180 and UE 104. It is noteworthy that the transmit direction and receive direction of BS 180 may be the same or different. Similarly, the transmit direction and receive direction of UE 104 may be the same or different.

[0047] Wireless communication network 100 also includes Wi-Fi AP 150 that communicates with Wi-Fi stations (STAs) 152 via communication links 154 in, for example, the 2.4 GHz and / or 5 GHz unlicensed spectrum.

[0048] Certain UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 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), a physical sidelink control channel (PSCCH), and / or a physical sidelink feedback channel (PSFCH).

[0049] The EPC 160 may include various functional components, including: 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 / or a packet data network (PDN) gateway 172, such as in the depicted example. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, the MME 162 provides bearer and connection management.

[0050] Generally speaking, user Internet Protocol (IP) packets are delivered through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation and other functions. The PDN Gateway 172 and the BM-SC 170 are connected to the IP Services 176, which may include, for example, the Internet, an Intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) streaming media service, and / or other IP services.

[0051] The BM-SC 170 may provide functionality for MBMS user service configuration and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS delivery, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and / or may be used to schedule MBMS delivery. The MBMS Gateway 168 may be used to distribute MBMS services to BSs 102 belonging to a multicast broadcast single frequency network (MBSFN) area broadcasting a specific service, and / or may be responsible for session management (start / stop) and for collecting eMBMS related charging information.

[0052] 5GC 190 may include various functional components, including: access and mobility management function (AMF) 192, other AMFs 193, session management function (SMF) 194, and user plane function (UPF) 195. AMF 192 may communicate with unified data management (UDM) 196.

[0053] AMF 192 is a control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides, for example, Quality of Service (QoS) flow and session management.

[0054] Internet Protocol (IP) packets are delivered through UPF 195, which is connected to IP Services 197 and provides IP address allocation for UEs and other functions for 5GC 190. IP Services 197 may include, for example, the Internet, Intranet, IMS, PS streaming services, and / or other IP services.

[0055] The wireless communication network 100 also includes a bandwidth part (BWP) component 198, which can be configured to perform Fig.15 Operation 1500 and / or Fig.18 The wireless communication network 100 also includes a BWP component 199, which can be configured to perform Fig.16 Operation 1600 and / or Fig.19 Operation 1900.

[0056] In various aspects, a network entity or network node may be implemented as a converged BS, a decomposed BS, a component of a BS, an integrated access and backhaul (IAB) node, a relay node, a sidelink node, to name a few examples.

[0057] Figure 2 An example decomposed BS 200 architecture is depicted. The decomposed BS 200 architecture may include one or more central units (CUs) 210 that may communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed BS units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a service management and orchestration (SMO) framework 205, or both. The CU 210 may communicate with one or more distributed units (DUs) 230 via respective midhaul links, such as an F1 interface. The DU 230 may communicate with one or more radio units (RUs) 240 via respective fronthaul links. The RU 240 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 240.

[0058] Each of the units (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO framework 205) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of the unit may be configured to communicate with one or more of the other units via a transmission medium. For example, the units may include a wired interface configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally or alternatively, the unit may include a wireless interface that may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver) configured to receive signals on a wireless transmission medium or send signals to one or more of the other units, or both.

[0059] In some aspects, CU 210 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 210. CU 210 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP)), control plane functionality (e.g., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 210 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 210 may be implemented to communicate with DU 230 for network control and signaling.

[0060] DU 230 may correspond to a logical unit that includes one or more BS functions for controlling the operation of one or more RUs 240. In some aspects, DU 230 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to a functional split such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0061] The lower layer functionality may be implemented by one or more RUs 240. In some deployments, a RU 240 controlled by a DU 230 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable the implementation of the DU 230 and the CU 210 in a cloud-based RAN architecture (such as a vRAN architecture).

[0062] The SMO framework 205 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some specific implementations, the SMO framework 205 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 211) via the O1 interface. Additionally, in some specific implementations, the SMO framework 205 may communicate directly with one or more RUs 240 via the O1 interface. The SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of the SMO framework 205 .

[0063] The non-RT RIC 215 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 225. The non-RT RIC 215 may be coupled to or in communication with the near-RT RIC 225 (such as via an A1 interface). The near-RT RIC 225 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 210, one or more DUs 230, or both, and the O-eNB with the near-RT RIC 225.

[0064] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 225 and may be received from a non-network data source or from a network function at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 205 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0065] Figure 3 Aspects of an example BS 102 and UE 104 are depicted.

[0066] In general, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a-334t (collectively 334), transceivers 332a-332t (collectively 332) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., data source 312) and wireless reception of data (e.g., data sink 339). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement various functions described herein related to wireless communication.

[0067] BS 102 includes a controller / processor 340 that can be configured to perform various functions related to wireless communication. In the depicted example, controller / processor 340 includes a BWP component 341, which can represent Figure 1 The BWP component 199 of the BS 102. It is worth noting that, although depicted as an aspect of the controller / processor 340, in other specific implementations, the BWP component 341 may additionally or alternatively be implemented in various other aspects of the BS 102.

[0068] In general, the UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-352r (collectively 352), transceivers 354a-354r (collectively 354) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., retrieved from a data source 362) and wireless reception of data (e.g., provided to a data sink 360). The UE 104 includes a controller / processor 380 that can be configured to implement various functions described herein related to wireless communications.

[0069] UE 104 includes a controller / processor 380 that can be configured to perform various functions related to wireless communication. In the depicted example, the controller / processor 380 includes a BWP component 381, which can represent Figure 1 The BWP component 198 of the UE 104. It is worth noting that, although depicted as an aspect of the controller / processor 380, in other specific implementations, the BWP component 381 can additionally or alternatively be implemented in various other aspects of the UE 104.

[0070] Regarding example downlink transmissions, BS 102 includes a transmit processor 320 that can receive data from a data source 312 and control information from a controller / processor 340. The control information can be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical HARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), and / or others. In some examples, the data can be for a physical downlink shared channel (PDSCH).

[0071] The transmit processor 320 may process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmit processor 320 may also generate reference symbols (such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS)).

[0072] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, and / or reference symbols, where applicable, and may provide an output symbol stream to a modulator (MOD) in a transceiver 332a-332t. Each modulator in the transceiver 332a-332t may process a corresponding output symbol stream to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators in the transceivers 332a-332t may be transmitted via antennas 334a-334t, respectively.

[0073] To receive downlink transmissions, UE 104 includes antennas 352a-352r that can receive downlink signals from BS 102 and can provide received signals to demodulators (DEMODs) in transceivers 354a-354r, respectively. Each demodulator in transceivers 354a-354r can condition (e.g., filter, amplify, downconvert, and digitize) a corresponding received signal to obtain input samples. Each demodulator can further process the input samples to obtain received symbols.

[0074] A MIMO detector 356 may obtain received symbols from all demodulators in transceivers 354a-354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 104 to a data sink 360, and provide decoded control information to a controller / processor 380.

[0075] With respect to example uplink transmissions, the UE 104 also includes a transmit processor 364 that may receive and process data from a data source 362 (e.g., for a PUSCH) and control information from a controller / processor 380 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 364 may also generate reference symbols for reference signals (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 364 may be pre-decoded by a TX MIMO processor 366, if applicable, further processed by a modulator in the transceivers 354a-354r (e.g., for SC-FDM), and transmitted to the BS 102.

[0076] At BS 102, uplink signals from UE 104 may be received by antennas 334 a-334 t, processed by demodulators in transceivers 332 a-332 t, detected by MIMO detector 336 if applicable, and further processed by receive processor 338 to obtain decoded data and control information transmitted by UE 104. Receive processor 338 may provide decoded data to data sink 339 and decoded control information to controller / processor 340.

[0077] Memories 342 and 382 may store data and program codes for BS 102 and UE 104, respectively.

[0078] The scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.

[0079] In various aspects, the BS 102 may be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 312, a scheduler 344, a memory 342, a transmit processor 320, a controller / processor 340, a TX MIMO processor 330, a transceiver 332a-332t, an antenna 334a-334t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 334a-334t, a transceiver 332a-332t, a RX MIMO detector 336, a controller / processor 340, a receive processor 338, a scheduler 344, a memory 342, and / or other aspects described herein.

[0080] In various aspects, the UE 104 may also be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 362, a memory 382, ​​a transmit processor 364, a controller / processor 380, a TX MIMO processor 366, a transceiver 354a-354t, an antenna 352a-352t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 352a-352t, a transceiver 354a-354t, a RX MIMO detector 356, a controller / processor 380, a receive processor 358, a memory 382, ​​and / or other aspects described herein.

[0081] In some aspects, the processor may be configured to perform various operations (such as those associated with the methods described herein) and send (output) data to or receive (obtain) data from another interface configured to send or receive data, respectively.

[0082] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes a method for use in a wireless communication network such as Figure 1 Various aspects of the data structure of the wireless communication network 100).

[0083] Specifically, Figure 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5G NR) frame structure, Figure 4B is a diagram 430 illustrating an example of a DL channel within a 5G subframe, Figure 4C is a diagram 450 illustrating an example of a second subframe within a 5G frame structure, and Figure 4D FIG480 is a diagram illustrating an example of UL channels within a 5G subframe.

[0084] Wireless communication networks can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single Carrier Frequency Division Multiplexing (SC-FDM) can be used to maximize the system bandwidth (e.g., Figure 4B and Figure 4D ) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0085] The wireless communication frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to either DL or UL. The wireless communication frame structure may also be time division duplex (TDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to both DL and UL.

[0086] exist Figure 4A and Figure 4C In the wireless communication frame structure, TDD is used, where D is DL, U is UL, and X can be used flexibly between DL / UL. The UE can be configured with a time slot format (dynamically configured by DL control information (DCI) or semi-statically / statically configured by radio resource control (RRC) signaling) through the received time slot format indicator (SFI). In the depicted example, the 10ms frame is divided into 10 equally sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. The subframe may also include a micro-time slot, which generally has fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0087] In certain aspects, the number of slots within a subframe is based on the slot configuration and parameter set. For example, for slot configuration 0, different parameter sets (μ) 0 to 5 allow for 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different parameter sets 0 to 2 allow for 2, 4, and 8 slots per subframe, respectively. Thus, for slot configuration 0 and parameter set μ, there are 14 symbols / slot and 2μ slots / subframe. The subcarrier spacing and symbol length / duration are a function of the parameter set. The subcarrier spacing may be equal to 2 μ × 15kHz, where μ is parameter set 0 to 5. Thus, parameter set μ=0 has a subcarrier spacing of 15kHz, and parameter set μ=5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figure 4A , Figure 4B , Figure 4Cand Figure 4D An example is provided for slot configuration 0 with 14 symbols per slot and parameter set μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0088] like Figure 4A , Figure 4B , Figure 4C and Figure 4D As depicted in , a resource grid can be used to represent a frame structure. Each time slot includes a resource block (RB) (also called a physical RB (PRB)) extending, for example, 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0089] like Figure 4A As illustrated, some of the REs carry data for UEs (eg, Figure 1 and Figure 3 The RS may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0090] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated.The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE Groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0091] The primary synchronization signal (PSS) may be in symbol 2 of a particular subframe of a frame. The PSS is transmitted by a UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identification.

[0092] A 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.

[0093] Based on the physical layer identifier and the physical layer cell identifier group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. 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 system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information (such as system information blocks (SIBs)) that is not sent via the PBCH, and / or paging messages.

[0094] like Figure 4C As illustrated, some of the REs carry DMRS for channel estimation at the BS (indicated as R for a particular configuration, but other DMRS configurations are possible). The UE may send a DMRS for PUCCH and a DMRS for PUSCH. The PUSCH DMRS may be sent, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be sent in different configurations depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used. The UE 104 may send a sounding reference signal (SRS). The SRS may be sent, for example, in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the teeth of the comb. The SRS may be used by the BS for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0095] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as 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 HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0096] Example Full Duplex (FD) Use Case

[0097] The technology presented herein is directed to supporting bandwidth part (BWP) (e.g., frequency band) pairs with non-aligned center frequencies for full-duplex (FD) operation. FD allows simultaneous transmission between nodes (e.g., user equipment (UE) and network entities). In a half-duplex (HD) system, communications flow in one direction at a time.

[0098] In some cases, after initial network access, the UE is configured with one or more BWPs. Each BWP may include a parameter set (e.g., including a time slot), a physical resource block (PRB) grid to index mapping, and / or a control resource set (CORESET) parameter set. The PRB grid may include multiple subcarriers in frequency and multiple symbols in time. The CORESET may indicate downlink control information (DCI) (e.g., carried in a physical downlink control channel (PDCCH)). The DCI may indicate which configured BWPs may be used for (e.g., activated or deactivated) downlink data transmission (e.g., in a physical downlink shared channel (PDSCH)).

[0099] The technology presented herein can be applied in various frequency bands for new radio (NR). For example, for the higher frequency bands called frequency range (FR) 4 (e.g., 52.6 GHz-114.25 GHz), an orthogonal frequency division multiplexing (OFDM) waveform with a very large subcarrier spacing (SCS; 960 kHz-3.84 MHz) is required to combat severe phase noise. Due to the large SCS, the time slot length tends to be very short. In the lower frequency band called FR2 (24.25 GHz to 52.6 GHz) with an SCS of 120 kHz, the time slot length is 125 μSec, while in FR4 with 960 kHz, the time slot length is 15.6 μSec. In some cases, a frequency band called FR2x may be used.

[0100] There are various motivations for utilizing FD communications, for example, to perform simultaneous uplink / downlink transmissions in FR2. In some cases, FD capabilities may enable flexible time division duplex (TDD) capabilities and may exist at the network entity or the UE, or both. For example, at the UE, uplink transmissions may be transmitted from one antenna panel and downlink reception may be performed at another antenna panel. In another example, at a gNodeB (gNB), uplink transmissions may come from one panel and downlink reception may be performed at another panel.

[0101] FD capability may depend on beam separation (e.g., self-interference between downlink and uplink, clutter echo, etc.). FD capability may mean that the UE or gNB is able to use frequency division multiplexing (FDM) or space division multiplexing (SDM) on timeslots that are conventionally reserved for uplink-only timeslots or downlink-only timeslots (or flexible timeslots that may be dynamically indicated as uplink or downlink).

[0102] Potential benefits of FD communications include reduced latency (e.g., it is possible to receive downlink signals in what are conventionally considered uplink-only time slots, which may result in latency savings), coverage enhancement, spectral efficiency enhancement (per cell and / or per UE), and / or overall more efficient resource utilization.

[0103] Figures 5 to 7 An example use case for FD communication is illustrated. Figure 8 Some possible characteristics of these use cases are summarized.

[0104] like Figure 5 As illustrated, for a first use case (e.g., use case 1), a UE transmits on the uplink to a second transmitter receiver point (TRP) while communicating on the downlink with a first TRP 1. For this use case, FD is disabled at the gNB (i.e., TRP) and enabled at the UE.

[0105] like Figure 6 As illustrated, for a second use case (e.g., Use Case 2), a gNB communicates with a second UE (UE2) on the uplink while simultaneously communicating with a first UE (UE 1) on the downlink. For this use case, FD is enabled at the gNB and disabled at the UE. The use case where FD is enabled at the gNB and disabled at the UE may also be suitable for integrated access and backhaul (IAB) applications (e.g., such as Figure 8 as shown in the table).

[0106] like Figure 7 As illustrated, for the third use case (e.g., use case 3), the UE communicates with the gNB while receiving on the downlink. For this use case, FD is enabled at both the gNB and the UE.

[0107] like Fig. 9 As illustrated, FD is enabled at the gNB and disabled at the UE. For example, a first gNB is communicating with one UE on the uplink while communicating with another UE on the downlink. Similarly, a second gNB is communicating with one UE on the uplink while communicating with another UE on the downlink. In some cases, the specific implementation of the FD communication / TDD system may pose some challenges. One of them is cross-link interference (CLI), which occurs when one gNB (e.g., the first gNB) is transmitting while another gNB (e.g., the second gNB) is receiving in the same frequency band. gNBs typically transmit at higher power and have better propagation conditions between them, i.e., the path loss between gNBs is lower than the link between the gNB and the UE. Therefore, CLI may be significant when a gNB in ​​the uplink is subject to downlink interference from another gNB. This may then result in a reduction in throughput. In this case, CLI may also exist between UEs when one UE is transmitting and another UE is receiving in the same frequency band.

[0108] like Fig.10As illustrated, FD is enabled at the gNB and UE. For example, a first gNB is communicating with a first UE on both the downlink and uplink while communicating with a second UE on the downlink. In this case, CLI may exist between gNBs when one gNB is transmitting and another gNB is receiving in the same frequency band. In this case, CLI may also exist between UEs (e.g., from a first UE to a second UE) when one UE is transmitting and another UE is receiving in the same frequency band.

[0109] like Fig.11 As illustrated, HD is enabled at the gNB and FD is enabled at the UE. For example, a first gNB communicates with a first UE on the uplink, and a second gNB communicates with the first UE and the second UE on the downlink. The first UE communicates with the first gNB on the uplink while communicating with the second gNB on the downlink. In this case, when one gNB is transmitting and the other gNB is receiving in the same frequency band, there may be CLI between gNBs (e.g., from the second gNB to the first gNB). In this case, when one UE is transmitting and the other UE is receiving in the same frequency band, there may also be CLI between UEs (e.g., from the first UE to the second UE).

[0110] like Fig.12 As illustrated, a parent node (e.g., an IAB donor node) is associated with two child nodes (e.g., IAB nodes). The IAB nodes may be network entities. Both IAB nodes are FD enabled. For example, each IAB node communicates with one UE on the uplink while communicating with another UE on the downlink. In this case, when one IAB node is transmitting and the other IAB node is receiving in the same frequency band, there may be a CLI between the IAB nodes.

[0111] Aspects related to non-aligned center frequencies on DL BWP and UL BWP

[0112] In current time division duplex (TDD) or half-duplex systems, a network entity may configure a downlink bandwidth part (BWP) and an uplink BWP with aligned center frequencies. For example, in the case of a TDD system, a BWP pair (e.g., a downlink BWP and an uplink BWP with the same BWP ID) must have the same center frequency (e.g., an overlap of the downlink BWP and the uplink BWP). This prevents the use of a BWP pair for full-duplex operation.

[0113] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for supporting BWP pairs with non-aligned center frequencies for full-duplex operation. For example, a user equipment (UE) may indicate the capability of non-aligned center frequencies on a downlink BWP and an uplink BWP. A network entity may configure non-aligned downlink BWP and uplink BWP for a UE for sub-band / frequency division multiplexing (FDM) full-duplex operation. The downlink BWP and uplink BWP may be separated from each other or partially overlapped.

[0114] As noted above, the techniques proposed herein support BWP pairs with non-aligned center frequencies for full-duplex operation. Full-duplex operation may result in reduced latency (e.g., because it is possible to receive downlink signals in uplink time slots). The techniques proposed herein may refer to Figures 13 to 16 Come to understand.

[0115] like Fig.13 As illustrated, at 1302, a UE (e.g., such as Figure 1 UE 104 in the wireless communication network 100) to a network entity (e.g., such as Figure 1 A gNodeB (gNB) or BS 102) in the wireless communication network 100 sends an indication of the UE's ability to support downlink and uplink BWP pairs with non-aligned center frequencies.

[0116] At 1304, the network entity sends signaling to the UE to configure the UE with a downlink BWP and an uplink BWP having non-aligned center frequencies for full-duplex operation according to the indicated UE capabilities.

[0117] In some aspects, the downlink BWP and the uplink BWP may not overlap. Fig.14 As illustrated, the downlink BWP and the uplink BWP may be separated by a guard band (GB). In certain aspects, the downlink BWP and the uplink BWP may partially overlap. In certain aspects, the full-duplex operation is in a non-paired TDD spectrum.

[0118] Fig.15 Example operations 1500 for wireless communication are illustrated. Operations 1500 may be performed, for example, by a UE (e.g., such as Figure 1 Operation 1500 may be implemented as a processor (e.g., Figure 3 In addition, the signal transmission and reception performed by the UE in operation 1500 may be performed by one or more antennas (e.g., Figure 3In some aspects, the signal transmission and / or reception by the UE may be implemented by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 380).

[0119] Operations 1500 begin at 1502 by sending an indication of the UE's ability to support downlink and uplink BWP pairs with non-aligned center frequencies. For example, the UE may use Figure 1 or Figure 3 The UE 104 and / or Fig. 20 The antenna and / or transmitter / transceiver component of the device shown is used to send the indication.

[0120] At 1504, the UE receives signaling to configure the UE with a downlink BWP and an uplink BWP with non-aligned center frequencies for full-duplex operation according to the indicated UE capabilities. For example, the UE may use Figure 1 or Figure 3 The UE 104 and / or Fig. 20 The antenna and / or receiver / transceiver components of the device are shown to receive the signaling.

[0121] It should be noted that Fig.15 This is merely one example of a method, and other methods including fewer, additional, or alternative steps are possible consistent with the present disclosure.

[0122] Fig.16 Example operations 1600 for wireless communication are illustrated. Operations 1600 may be performed, for example, by a network entity (e.g., such as Figure 1 Operation 1600 may be implemented as a processor (e.g., Figure 3 In addition, the signal transmission and reception performed by the network entity in operation 1600 may be performed by one or more antennas (e.g., Figure 3 In some aspects, the transmission and / or reception of signals by the network entity may be achieved by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 340).

[0123] Operations 1600 begin at 1602 by receiving an indication of a UE's ability to support downlink and uplink BWP pairs with non-aligned center frequencies. For example, a network entity may use Figure 1 or Figure 3 BS102 and / or Fig.21 The antenna and / or receiver / transceiver assembly of the device is shown to receive the indication.

[0124] At 1604, the network entity configures the UE with a downlink BWP and an uplink BWP with non-aligned center frequencies for full-duplex operation according to the indicated UE capabilities. For example, the network entity may use Figure 1 or Figure 3 BS102 and / or Fig.21 The antenna and / or transmitter / transceiver components of the apparatus shown are used to configure a UE.

[0125] It should be noted that Fig.16 This is merely one example of a method, and other methods including fewer, additional, or alternative steps are possible consistent with the present disclosure.

[0126] Aspects related to changing the transmitter (TX) radio frequency (RF) bandwidth (BF) and receiver (RX) RF BW

[0127] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for supporting changing radio frequency (RF) bandwidth (BF). For example, when a user equipment (UE) has the capability to change the transmit RF BW and / or receive RF BW, the UE can switch from RF wideband half-duplex transmit and / or receive operation to partial downlink / receive or uplink / transmit RF band frequency division multiplexing (FDM) full-duplex operation.

[0128] The technology proposed in this article for supporting the change of the transmit RF BW and / or the receive RF BW can be referred to Figures 17 to 19 Come to understand.

[0129] like Fig.17 As illustrated, at 1702, a UE (e.g., such as Figure 1 UE 104 in the wireless communication network 100) to a network entity (e.g., such as Figure 1 A gNodeB (gNB) or BS 102) in the wireless communication network 100 sends an indication of the UE capability to change the RF BW used for at least one of reception or transmission.

[0130] At 1704, the network entity sends signaling to the UE to configure the UE to switch from half-duplex RF BW operation to full-duplex RF BW operation according to the indication.

[0131] In certain aspects, the UE's hardware may be capable of dynamically changing the RF BW. In certain aspects, the UE's hardware may not be capable of dynamically changing the RF BW.

[0132] In some aspects, the RF BW is a transmit RF BW. In some aspects, the RF BW is a receive RF BW.

[0133] In some aspects, the half-duplex RF BW operation is an RF wideband half-duplex transmit operation. In some aspects, the half-duplex RFBW operation is an RF wideband half-duplex receive operation.

[0134] In certain aspects, full-duplex RF BW operation is partial downlink or receive full-duplex RF BW operation. In certain aspects, full-duplex RF BW operation is partial uplink or transmit full-duplex RF BW operation.

[0135] Fig.18 Example operations 1800 for wireless communication are illustrated. Operations 1800 may be performed, for example, by a UE (e.g., such as Figure 1 Operation 1800 may be implemented as a processor (e.g., Figure 3 In addition, the signal transmission and reception performed by the UE in operation 1800 may be performed by one or more antennas (e.g., Figure 3 In some aspects, the signal transmission and / or reception by the UE may be implemented by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 380).

[0136] Operations 1800 begin at 1802 by sending an indication of a UE capability to change the RF BW used for at least one of reception or transmission. For example, the UE may use Figure 1 or Figure 3 The UE 104 and / or Fig. 22 The antenna and / or transmitter / transceiver component of the device shown is used to send the indication.

[0137] At 1804, the UE receives signaling to configure the UE to switch from half-duplex RF BW operation to full-duplex RF BW operation according to the indication. For example, the UE may use Figure 1 or Figure 3 The UE 104 and / or Fig. 22 The antenna and / or receiver / transceiver components of the device are shown to receive the signaling.

[0138] It should be noted that Fig.18 This is merely one example of a method, and other methods including fewer, additional, or alternative steps are possible consistent with the present disclosure.

[0139] Fig.19 Example operations 1900 for wireless communication are illustrated. Operations 1900 may be performed, for example, by a network entity (e.g., such as Figure 1Operation 1900 may be implemented as a process in one or more processors (e.g., Figure 3 In addition, the signal transmission and reception performed by the network entity in operation 1900 may be performed by one or more antennas (e.g., Figure 3 In some aspects, the transmission and / or reception of signals by the network entity may be achieved by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 340).

[0140] Operations 1900 begin at 1902 by receiving an indication of a UE capability to change the RF BW for at least one of reception or transmission. For example, the network entity may use Figure 1 or Figure 3 BS102 and / or Fig.23 The antenna and / or receiver / transceiver assembly of the device is shown to receive the indication.

[0141] At 1904, the network entity configures the UE to switch from half-duplex RF BW operation to full-duplex RFBW operation according to the indication. For example, the network entity may use Figure 1 or Figure 3 BS102 and / or Fig.23 The antenna and / or transmitter / transceiver components of the apparatus shown are used to configure a UE.

[0142] It should be noted that Fig.19 This is merely one example of a method, and other methods including fewer, additional, or alternative steps are possible consistent with the present disclosure.

[0143] The techniques proposed herein have several advantages. For example, when a network entity schedules multiple UEs for full-duplex operation, the network entity may prioritize selecting a UE from the multiple UEs for full-duplex operation (if other conditions are similar) based on the UE's capabilities (i.e., changing the RF BW for reception and / or transmission). This may prevent cross-link interference (CLI) between the selected UEs (e.g., because a downlink UE may receive inter-UE CLI from an uplink UE in a wideband reception RF BW when the UE does not have the capability to switch to a partial reception RF BW).

[0144] In certain aspects, when both the downlink UE and the uplink UE have RF filters and certain parameters (e.g., a minimum GB between the downlink BWP and the uplink BWP) are met to avoid leakage, the network entity may skip configuring inter-UE CLI measurements because leakage can be completely avoided based on the minimum GB configured for FDM full-duplex operation.

[0145] In certain aspects, the network entity may schedule FDM full-duplex operation for downlink UEs with closer interferers (e.g., uplink UEs) in separate downlink BWPs and uplink BWPs. In certain aspects, the network entity may schedule FDM full-duplex operation for downlink UEs and uplink UEs with higher data rates when the UEs are at the same distance from each other.
