Technical Field

[0003] Aspects of the present disclosure relate to wireless communications and, more particularly, to techniques for managing uplink transmissions in sub-band full-duplex (SBFD) time slots. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts or other similar types of services. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available wireless communication system resources with the multiple users.

[0005] Although wireless communication systems have made tremendous technical advances over the years, challenges still exist. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and wireless receivers. Therefore, there is a continued desire to improve the technical performance of wireless communication systems, including, for example: improving the speed and data carrying capacity of communications, improving the efficiency of using shared communication media, reducing the power used by transmitters and receivers while performing communications, improving the reliability of wireless communications, avoiding redundant transmissions and / or receptions and related processing, improving the coverage of wireless communications, increasing the number and types of devices that can access wireless communication systems, increasing the ability of different types of devices to communicate with each other, increasing the number and types of available wireless communication media, etc. Therefore, there is a need to further improve wireless communication systems to overcome the aforementioned technical challenges and other challenges.

[0031] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for sub-band filtering by a user equipment (UE).

[0032] The term full-duplex (FD) describes the simultaneous sending and receiving of data over a single channel. Therefore, FD devices are capable of bidirectional network data transmission at the same time. In contrast, half-duplex (HD) devices can only transmit in one direction at a time. With HD mode, data can move in both directions, but not at the same time.

[0033] If a user equipment (UE) operates in HD mode and a gNodeB (gNB) operates in sub-band FD (SBFD) or intra-band FD (IBFD), interference from multiple sources may occur at the UE. For example, the interference may include inter-cell interference (ICI) from other gNBs, intra-cell cross-link interference (CLI) from UEs in the same cell, and inter-cell CLI from UEs in neighboring cells. Self-interference may also occur for FD UEs, where the UE's uplink transmissions interfere with the reception of downlink transmissions. These interference sources can cause severe problems, including reduced spectral efficiency, increased power consumption, and poor UE performance.

[0034] Various aspects of the present disclosure provide techniques that can help mitigate this potential source of interference by using sub-band filtering at the UE. The techniques proposed herein can have significant benefits. For example, the sub-band filtering proposed herein can allow the network to have greater flexibility in scheduling, given the potential for reducing interference, leakage, and sub-band emissions (SBE).

[0035] Introduction to Wireless Communication Networks

[0036] The techniques and methods described herein can be used in various wireless communication networks. Although terms commonly associated with 3G, 4G and / or 5G wireless technologies may be used herein to describe various aspects, various aspects of the present disclosure may also be applicable to other communication systems and standards not explicitly mentioned herein.

[0037] Figure 1 An example of a wireless communication network 100 is depicted in which various aspects described herein may be implemented.

[0038] Typically, 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., a user equipment (UE), a base station (BS), a component of a BS, a server, etc.). For example, various functions of a network and various devices associated with and interacting with the network can be considered network entities. In addition, the wireless communication network 100 includes terrestrial aspects (e.g., ground-based network entities (e.g., BS 102)) and non-terrestrial aspects (e.g., 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 user equipment).

[0039] In the depicted example, the wireless communication network 100 includes a BS 102, a UE 104, and one or more core networks (e.g., 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.

[0040] Figure 1 Various example UEs 104 are depicted, which may generally include: a mobile 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 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, etc.

[0041] BS 102 wirelessly communicates with UE 104 (e.g., sends 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 reverse link) transmissions from UE 104 to BS 102 and / or downlink (DL) (also referred to as forward link) transmissions from BS 102 to UE 104. Communication link 120 may use multiple-input and multiple-output (MIMO) antenna technology including spatial multiplexing, beamforming, and / or transmit diversity in various aspects.

[0042] BS 102 may generally include: Node B, enhanced Node B (eNB), next generation enhanced Node B (ng-eNB), next generation Node B (gNB or gNode B), access point, base transceiver, radio base station, radio transceiver, transceiver function, transmission and reception point, etc. 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 (e.g., a stadium)), a femto cell (relatively small geographic area (e.g., a home)), and / or other types of cells.

[0043] 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 the base station can 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, etc., to name a few examples. In another example, various aspects of the base station can be virtualized. In general, a base station (e.g., BS102) can include components located at a single physical location or components located at various physical locations. In an example in which the base station includes components located at various physical locations, each component can perform a function so that each component jointly implements a function similar to that of a base station located at a single physical location. In some aspects, a base station including components located at various physical locations can be referred to as a decomposed radio access network architecture, for example, an open RAN (O-RAN) or a virtualized RAN (VRAN) architecture. Figure 2 An example decomposed base station architecture is depicted and described.

[0044] 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 the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may be interfaced 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 be interfaced 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) via a third backhaul link 134 (e.g., an X2 interface), which may be wired or wireless.

[0045] 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, frequency channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410 MHz–7125 MHz, which is commonly referred to (interchangeably) as “Sub-6 GHz”. Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24250 MHz–52600 MHz, which is sometimes referred to (interchangeably) as “millimeter wave” (“mmW” or “mmWave”). A base station (e.g., a mmWave base station such as BS180) configured to communicate using mmWave / near mmWave radio frequency bands may utilize beamforming (e.g., 182) with a UE (e.g., 104) to improve path loss and range.

[0046] For example, the communication link 120 between the BS 102 and the UE 104 may be through one or more carriers, which may have different bandwidths (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) and may be aggregated in various aspects. The carriers may be adjacent to each other, or may not be adjacent. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​than for UL).

[0047] Communications using higher frequency bands can have higher path loss and shorter range than communications using lower frequencies. Figure 1180) can utilize beamforming 182 with UE 104 to improve path loss and range. For example, BS 180 and UE 104 can each include multiple antennas, such as antenna elements, antenna panels and / or antenna arrays, to facilitate beamforming. In some cases, BS 180 can send beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 can receive beamformed signals from BS 180 in one or more receive directions 182". UE 104 can also send beamformed signals to BS 180 in one or more transmit directions 182". BS 180 can also receive beamformed signals from UE 104 in one or more receive directions 182'. BS 180 and UE 104 can then perform beam training to determine the best receive direction and transmit direction for each of BS 180 and UE 104. It is worth noting that the transmit direction and receive direction for BS 180 can be the same or can be different. Similarly, the transmit direction and receive direction for UE 104 may be the same or different.

[0048] Wireless communication network 100 also includes Wi-Fi AP 150 that communicates with Wi-Fi station (STA) 152 via communication link 154 in, for example, the 2.4 GHz and / or 5 GHz unlicensed spectrum.

[0049] 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).

[0050] 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. Typically, the MME 162 provides bearer and connection management.

[0051] Typically, user Internet Protocol (IP) packets are transmitted 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 IP services 176, which may include, for example, the Internet, an intranet, an IP Multimedia Subsystem (IMS), a packet switched (PS) streaming service, and / or other IP services.

[0052] The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmissions, 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 transmissions. The MBMS Gateway 168 may be used to distribute MBMS services to BSs 102 belonging to a multicast broadcast single frequency network (MBSFN) area of ​​a broadcast specific service, and / or may be responsible for session management (start / stop) and collecting charging information related to eMBMS.

[0053] 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.

[0054] 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.

[0055] Internet Protocol (IP) packets are transmitted through UPF 195, which is connected to IP services 197 and provides UE IP address allocation 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.

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

[0057] Figure 2An example decomposed base station 200 architecture is depicted. The decomposed base station 200 architecture may include one or more central units (CUs) 210, which may communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed base station units (e.g., 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 corresponding mid-haul links (e.g., an F1 interface). The DU 230 may communicate with one or more radio units (RUs) 240 via corresponding fronthaul links. The RU 240 may communicate with corresponding UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served by multiple RUs 240 simultaneously.

[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 one or more interfaces, 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, a unit may include a wired interface that is configured to receive signals or send signals to one or more of the other units via a wired transmission medium. Additionally or alternatively, a unit may include a wireless interface that may include a receiver, a transmitter, or a transceiver (e.g., a radio frequency (RF) transceiver) that is configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, 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 configured to transmit signals with other control functions hosted by CU 210. CU 210 may be configured to process user plane functions (e.g., central unit-user plane (CU-UP)), control plane functions (e.g., central unit-control plane (CU-CP)), or a combination thereof. In some implementations, CU 210 may be logically divided into one or more CU-UP units and one or more CU-CP units. The CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface, for example, an E1 interface when implemented in an O-RAN configuration. As required for network control and signaling, CU 210 may be implemented to communicate with DU 230.

[0060] DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RU 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-level physical (PHY) layers (e.g., modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.), depending at least in part on functional partitioning (e.g., those defined by the Third Generation Partnership Project (3GPP)). In some aspects, DU 230 may also host one or more low PHY layers. Each layer (or module) may be implemented with an interface configured to transmit signals with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0061] The lower layer functions may be implemented by one or more RUs 240. In some deployments, the RU 240 controlled by the DU 230 may correspond to a logical node that hosts RF processing functions, or low PHY layer functions (e.g., performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, which is at least partially based on functional partitioning (e.g., lower layer functional partitioning). In this 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 communications and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable the DU 230 and the CU 210 to be implemented in a cloud-based RAN architecture (e.g., 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 (e.g., an O1 interface). For virtualized network elements, the SMO framework 205 may be configured to interact with a cloud computing platform (e.g., an open cloud (O-cloud) 290) via a cloud computing platform interface (e.g., an O2 interface) to perform network element lifecycle management (e.g., to instantiate virtualized network elements). Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some implementations, the SMO framework 205 may communicate with hardware aspects of the 4G RAN (e.g., an open eNB (O-eNB) 211) via an O1 interface. Additionally, in some implementations, the SMO framework 205 may communicate directly with one or more RUs 240 via an 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 implement 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 communicate with the near-RT RIC 225 (e.g., via an A1 interface). The near-RT RIC 225 may be configured to include logic functions that implement near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (e.g., via an E2 interface) that connects the near-RT RIC 225 to one or more CUs 210, one or more DUs 230, or both, and the O-eNB.

[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 adjust RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO framework 205 (e.g., via reconfiguration of O1) or via the creation of a RAN management policy (e.g., an A1 policy).

[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-t (collectively 334), transceivers 332a-t (collectively 332), which include 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 send and receive data between BS 102 and UE 104. BS 102 includes controller / processor 340, which can be configured to implement various functions related to wireless communication described herein.

[0067] In general, the UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-r (collectively, 352), transceivers 354a-r (collectively, 354) including modulators and demodulators and 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, which may be configured to implement various functions described herein related to wireless communications.

[0068] 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 other channels. In some examples, the data can be for a physical downlink shared channel (PDSCH).

[0069] 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, e.g., 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).

[0070] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols (if 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.

[0071] To receive downlink transmissions, UE 104 includes antennas 352a-352r, which can receive downlink signals from BS 102 and 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.

[0072] A MIMO detector 356 may obtain received symbols from all demodulators in the 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.

[0073] With respect to example uplink transmissions, the UE 104 further 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 precoded by a TX MIMO processor 366 (if applicable), further processed by a modulator in the transceiver 354a-354r (e.g., for SC-FDM), and transmitted to the BS 102.

[0074] At BS 102, uplink signals from UE 104 may be received by antennas 334a-t, processed by demodulators in transceivers 332a-332t, detected by MIMO detector 336 (if applicable), and further processed by receive processor 338 to obtain decoded data and control information sent by UE 104. Receive processor 338 may provide the decoded data to a data sink 339 and the decoded control information to a controller / processor 340.

[0075] Memories 342 and 382 may store data and program codes for BS 102 and UE 104, respectively.

[0076] A scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.

[0077] 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-t, an antenna 334a-t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 334a-t, a transceiver 332a-t, an RX MIMO detector 336, a controller / processor 340, a receive processor 338, a scheduler 344, a memory 342, and / or other aspects described herein.

[0078] In various aspects, the UE 104 may similarly 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-t, an antenna 352a-t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 352a-t, a transceiver 354a-t, a RX MIMO detector 356, a controller / processor 380, a receive processor 358, a memory 382, ​​and / or other aspects described herein.

[0079] In some aspects, the processor may be configured to perform various operations, such as those associated with the methods described herein, and to send (output) data to or receive (obtain) data from another interface that is configured to send or receive data, respectively.

[0080] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes the use of Figure 1 Various aspects of the data structure of a wireless communication network such as the wireless communication network 100.

[0081] In particular, 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 showing an example of DL channels within a 5G subframe, Figure 4C is a diagram 450 showing an example of a second subframe within a 5G frame structure, and Figure 4D FIG480 is a diagram showing an example of UL channels within a 5G subframe.

[0082] Wireless communication systems 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) will (for example, Figure 4B and Figure 4D The system bandwidth (as depicted in FIG. 1 ) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. The modulation symbols can be sent in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0083] 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 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.

[0084] exist Figure 4A and Figure 4C In the example depicted, the wireless communication frame structure is TDD, where D is DL, U is UL, and X is flexible for use between DL / UL. The UE can be configured with a slot format through a received slot format indicator (SFI) (dynamically through DL control information (DCI), or semi-statically / statically through radio resource control (RRC) signaling). In the depicted example, the 10ms frame is divided into 10 equally sized 1ms subframes. Each subframe may include one or more slots. In some examples, each slot may include 7 or 14 symbols, depending on the slot format. A subframe may also include a mini slot, which typically has fewer symbols than a full slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0085] In certain aspects, the number of time slots within a subframe is based on the time slot configuration and the digital scheme. For example, for time slot configuration 0, different digital schemes (μ) 0 to 5 allow 1, 2, 4, 8, 16, and 32 time slots per subframe, respectively. For time slot configuration 1, different digital schemes 0 to 2 allow 2, 4, and 8 time slots per subframe, respectively. Therefore, for time slot configuration 0 and digital scheme μ, there are 14 symbols / time slot and 2μ time slots / subframe. The subcarrier spacing and symbol length / duration are a function of the digital scheme. The subcarrier spacing can be equal to 2 μ × 15kHz, where μ is the digital scheme 0 to 5. Therefore, digital scheme μ=0 has a subcarrier spacing of 15kHz, and digital μ=5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely proportional to the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D An example is provided for slot configuration 0 with 14 symbols per slot and a digital scheme 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.

[0086] like Figure 4A , Figure 4B , Figure 4C and Figure 4D As depicted in , a resource grid can be used to represent the 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 multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0087] like Figure 4A As shown, some REs carry data for UEs (e.g. 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).

[0088] Figure 4B Examples of various DL channels within a subframe of a frame are shown.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.

[0089] 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.

[0090] A Secondary Synchronization Signal (SSS) may be within symbol 4 of a specific subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing.

[0091] 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 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 (e.g., system information block (SIB)) not sent via the PBCH, and / or paging messages.

[0092] like Figure 4C As shown, some REs carry DMRS (indicated as R for one particular configuration, but other DMRS configurations are also possible) for channel estimation at the base station. The UE may send DMRS for PUCCH and DMRS for PUSCH. For example, the PUSCH DMRS may be sent in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used, the PUCCH DMRS may be sent in different configurations. UE 104 may send a sounding reference signal (SRS). For example, the SRS may be sent 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 combs. The SRS may be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0093] Figure 4D Examples of various UL channels within a subframe of a frame are shown. The PUCCH may be located 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.

[0094] Full-duplex Communication Overview

[0095] As mentioned above, full-duplex (FD) devices are capable of bidirectional network data transmission at the same time. In contrast, half-duplex (HD) devices can only send in one direction at a time. With HD mode, data can move in both directions, but not at the same time.

[0096] Examples of FD communication include intra-band FD (IBFD) and sub-band FD. Figure 5A and Figure 5BAs shown in FIG. 1 , with IBFD, devices can transmit and receive on the same time and frequency resources. In this case, the downlink (DL) and uplink (UL) share the same IBFD time and frequency resources, which can completely overlap ( Figure 5A ) or partially overlap ( Figure 5B ).

[0097] like Figure 5C As shown, with SBFD (also known as flexible duplexing), a device can transmit and receive simultaneously, but using different frequency resources. In this case, the DL resources can be separated from the UL resources in the frequency domain by a guard band.

[0098] Interference to a UE and / or network entity (e.g., a base station such as a gNB or a node of a decomposed base station) operating in FD mode may come from neighboring nodes in the form of CLI and from self-interference (SI). Figure 5A , Figure 5B , Figure 5C and FIG. 5D illustrate example interference scenarios for various FD communication use cases.

[0099] like Fig. 6A As shown, the first scenario is when FD is enabled for the gNB (e.g., with non-overlapping UL / DL subbands) but disabled for each connected UE (which in turn can be enabled for half-duplex (HD) communication), and the gNBs communicate using FD functionality. In this case, CLI between UEs, SI from the FD gNB, and CLI between the gNB and neighboring gNBs interfere with FD communication.

[0100] like Figure 6B As shown, the second scenario is when FD is enabled for both the gNB and the FD UE / Customer Premises Equipment (CPE) connected to the gNB, the gNB communicates with the FD UE using the FD capability. If the gNB is connected to an HD UE together with the FD UE, the gNB communicates with the HD UE. In this case, the CLI between the UEs, the SI from the gNB and the FD UE, and the CLI between the FD gNB and the neighboring gNBs interfere with the FD communication.

[0101] like Figure 6CAs shown, the third scenario is when FD is enabled for two gNBs (e.g., in a multi-TRP scenario) and is enabled at one UE / CPE connected to the two gNBs. In this case, the two gNBs can communicate with the FD UE using the FD capability. If one of the two gNBs is connected to an HD UE along with the FD UE, the one gNB communicates with both the HD UE and the FD UE. In this case, the CLI between the UEs, the SI from the FD UE, and the CLI between the two gNBs can interfere with the FD communication.

[0102] Fig. 7A Various forms of interference for FD communications are also shown. As shown, if the UE is operating in HD mode and the gNB is operating in FD (mode) SBFD / IBFD, the sources of interference at the UE include inter-cell interference from other gNBs, intra-cell CLI from UEs in the same cell, and inter-cell CLI from UEs in neighboring cells. Additionally, self-interference may exist for full-duplex UEs, especially in SBFD time slots that include both uplink and downlink sub-bands, such as Figure 7B shown.

[0103] Enhanced UL transmit capability for sub-band full-duplex

[0104] Intra-cell and inter-cell UE interference between an aggressor UL UE and a victim UE receiving downlink (DL) communications can affect the DL reception of the victim UE in various ways. For example, the receiver automatic gain control (Rx AGC) can be biased by the interference signal, which may have a high strength (RSSI) compared to the DL signal.

[0105] This interference may have multiple adverse effects, such as: 1) increasing the noise figure because the UE will be operating in a higher gain state; 2) reducing the dynamic range of the DL signal; and 3) reducing the DL SINR due to leakage within the DL sub-band. In some scenarios, when the interference signal level is so high, this may lead to blocking of the radio frequency front end (RFFE) and the UE may not be able to receive the DL signal.

[0106] However, aspects of the present disclosure may help avoid such interference, for example, by utilizing RF sub-band filters (duplexers) at the UE side.The sub-band filters may operate within a component carrier (CC) bandwidth (BW) to reduce transmission to adjacent sub-bands within a CC.

[0107] The techniques proposed herein may help reduce inter-UE CLI through cleaner / reduced transmissions of the aggressor UE. The techniques proposed herein also include RF features and UE capabilities for inter-SB CLI mitigation.

[0108] These techniques can also help meet specific requirements defined for co-channel transmissions. Figure 8 As shown, such requirements may include UE transmit side (Tx side) inter-band emission (IBE) or sub-band emission (SBE), which is designed to control the unintentional emission of UL UE Tx on a specific resource block (RB) to other RBs. In some cases (e.g., in a TDD time slot), the network entity (e.g., gNB) may allocate other RBs to receive frequency division multiplexed (FDM) UL transmissions from other UEs in the same component carrier (CC). In sub-band full-duplex, other adjacent RBs may be used for downlink reception by other UEs. The requirements for inter-sub-band emission may be more stringent than the current IBE requirements to reduce out-of-sub-band emissions and leakage to other UEs receiving DL signals in adjacent sub-bands.

[0109] The technology proposed in this paper can help solve Fig.9A and Fig. 9B The scenario shown in , where three UEs (UE2, UE2 and UE3) are adjacent to each other and may be subject to CLI. In a conventional system, without deploying a UE sub-band duplexer, UE3 may not be scheduled within the SBFD timeslot.

[0110] In such a scenario, the UE sub-band filtering proposed herein may provide flexibility for scheduling uplink and downlink transmissions (eg, in SBFD logs) to different UEs by reducing adjacent sub-band emissions.

[0111] The UE can indicate to the network its capability of uplink transmission sub-band filtering. Knowing this capability can facilitate the network to schedule the UE while reducing inter-UE CLI. For example, the ability to perform sub-band filtering can determine whether the UE can be scheduled within the UL sub-band and which RBs (edge, center) and guard bands may be needed to schedule other DL UEs. For example, an advanced UE with sub-band Tx filtering capability can be safely assigned edge RBs with little (or zero) guard bands with DL UEs.

[0112] Additionally, knowing the UE capabilities for Tx subband filtering may reduce the burden of CLI measurement and reporting for the UE. Additionally, knowing the UE capabilities for Tx subband filtering may help meet the requirements for correct DL reception in the presence of potential inter-UE CLI.

[0113] You can refer to Fig. 10A , Fig. 10B and Fig. 10C to understand the impact of adjacent transmissions. Fig. 10AAs shown, three sub-bands 0-2 may be allocated for downlink, while two adjacent sub-bands 3-4 may be allocated for uplink. Fig. 10B and Fig. 10C The potential impact on the received SINR of the downlink sub-band of the victim UE (UE2) when the aggressor transmits on an adjacent sub-band is shown. Fig. 10B As shown, if the uplink transmission is on a closely adjacent sub-band, the degradation in receive SINR may be significant (e.g., 5-12 dB). Fig. 10C As shown, if the uplink transmissions are not immediately adjacent, the degradation in receive SINR may still be significant (eg, 3 dB).

[0114] You can refer to Fig.11 Various aspects of the present disclosure utilizing UE sub-band filtering may be understood by referring to call flow diagram 1100 of FIG. 11. As shown, a UE may indicate its uplink sub-band filtering capability. The network may use this information to schedule uplink transmissions for the UE (and downlink transmissions to other UEs) in SBFD time slots. The UE may then apply uplink sub-band filtering to send the scheduled uplink transmissions.

[0115] Figure 12 shows how applying sub-band Tx filtering at a UE can affect the received SINR of other UEs. Instead of degrading the SINR, Fig.11 A and Fig.11 As shown in B, by applying Tx sub-band filtering, the uplink transmission of a UE may not degrade the DL SINR of other UEs at all.

[0116] In some cases, the UE may report its capability to perform sub-band Tx filtering in order to meet the SBE (IBE) mask target or ASLR target. In some cases, the UE may indicate to the gNB its capability to perform Tx sub-band filtering within the component carrier bandwidth (CC BW), such as Fig.13 shown.

[0117] In some cases, the reported capability may be defined based on whether the UE supports or does not support sub-band Tx filtering. For UEs that support sub-band filtering capability, the UE may indicate the capability based on various options. According to one option, the UE may indicate the bandwidth of each sub-band for which it supports Tx sub-band filtering. According to another option, the UE may indicate the minimum frequency separation to the UL sub-band to reject cross-link interference (CLI). There are also multiple options for the granularity of the report, for example, per CC per band combination BC), per band per BC, or per band.

[0118] In some cases, new metrics (e.g., target requirements) may be defined for sub-band IBE in full-duplex time slots. Fig.14 As shown, the sub-band IBE may be defined similar to the spectrum emission mask (SEM). For example, the sub-band IBE may be defined based on the frequency offset from the edge of the sub-band according to the limit of the maximum emission. In some cases, the sub-band IBE may not depend on the UL modulation or error vector magnitude (EVM). In some cases, the sub-band IBE may not depend on the location where the actual UL occurs within the UL sub-band.

[0119] According to some aspects, such as Fig.15 As shown, an adjacent subband leakage ratio (ASLR) indicator (or target requirement) may be defined for adjacent subbands having the same BW as the uplink subband. In some cases, the size of the UL subband BW may be different from the size of the DL subband BW. Fig.16A As shown, according to one option, multiple ASLRs (eg, ASLR1, ASLR2, ...) may be defined for each virtual DL sub-band having the same BW as the UL sub-band. Fig. 16B As shown, according to another option, the ASLR may be defined based on the same BW and scaling factor. For example, the scaling factor may be defined based on the BW of another DL subband and the frequency offset of the virtual DL subband relative to the UL subband.

[0120] The ASLR is a fixed number or may be variable, e.g., depending on the UE's allocation. In some cases, there may be some flexibility in having different ASLR values ​​based on UL allocation (e.g., inner RBs may have relaxed requirements relative to outer / edge RBs). In some cases, there may be multiple ASLR indicators (target requirements), e.g., based on Tx power (TxPower). In some cases, a maximum power reduction (MPR) associated with SBFD may also be defined to reduce Tx power.

[0121] In some cases, some type of defined application time may be required for the DL sub-band filters and the UL sub-band filtering (duplexer). For example, this may be desirable because the UE may need a certain time to tune the RF sub-band filters. For example, when transitioning from a TDD-only UL / DL timeslot to a SBFD timeslot (or vice versa), from a single sub-band to a dual sub-band, or from a first sub-band to a second sub-band, a tuning time may be required.

[0122] In some cases, the timing may be defined at the slot level, e.g., similar to the bandwidth part (BWP) switching delay (e.g., 1 ms-3 ms). In other cases, the timing may be defined at the symbol level, e.g., utilizing one or more guard symbols (e.g., similar to antenna switching). In other cases, the timing may be in absolute time (e.g., in microseconds), similar to a defined transient period. In some cases, the timing requirements for retuning the sub-band filters may be included as part of the UE capability signaling.

[0123] In some cases, if a BWP is defined for each DL sub-band, this timing may be incorporated into the BWP switching time. If a BWP is not defined for each DL sub-band (e.g., if the DL / UL sub-band is within a BWP), the timing requirement may be reported or specified by the UE. In any case, the network (e.g., gNB) may avoid scheduling during such times.
