Abstract

This disclosure provides systems, apparatus, devices, and methods for channel measurement and reporting for a FD UE, including a computer program encoded on a storage medium. The user equipment (UE) can be configured to transmit UL signals in an uplink (UL) resource set configured by a base station. The UE can be further configured to monitor a downlink (DL) resource set configured by the base station, which is adjacent to or at least partially overlaps with the UL resource set. The UE can be further configured to determine the channel quality associated with the DL resource set based on the UL signals transmitted in the UL resource set. The UE can then be configured to transmit information to the base station indicating channel state feedback (CSF) based on the determined channel quality.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Greek application No. 20190100582, filed on December 30, 2019, entitled “CHANNEL MEASUREMENT AND REPORTING FOR FULL-DUPLEX USER EQUIPMENT”, the entire contents of which are hereby expressly incorporated by reference. Technical Field

[0003] In general, this disclosure relates to communication systems, and more specifically, to full-duplex (FD) channel measurement and reporting. Background Technology

[0004] Wireless communication systems have been widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems can use multiple access technologies that support communication with multiple users by sharing available system resources. Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0005] Such multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate across city limits, countries, regions, and even globally. An exemplary telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Mobile Broadband Evolution (CMB) initiative released by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)), and others. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology remain useful. Furthermore, these improvements can also be applied to other multiple access technologies and telecommunications standards that employ them. Summary of the Invention

[0006] To provide a basic understanding of one or more aspects of the invention, a brief overview of these aspects is given below. This overview is not an exhaustive summary of all anticipated aspects, nor is it intended to identify key or essential elements of all aspects, or to describe the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simple form as a prelude to the detailed description that follows.

[0007] Full-duplex (FD) communication is a wireless communication method that supports simultaneous transmission and reception of information on the same frequency band. In this way, spectral efficiency can be improved compared to half-duplex (HD) communication, which only supports information transmission / reception in one direction at a time.

[0008] Given the concurrent or simultaneous nature of FD communication, the transmission of uplink (UL) signals from a user equipment (UE) concurrently with the reception of downlink (DL) signals from a base station (BS) can affect channel quality, particularly in the channel between the BS and the UE. For example, uplink communication from the UE to the BS may degrade downlink communication from the BS to the UE (e.g., by introducing interference), and vice versa.

[0009] Therefore, for example, when the BS and UE use FD communication, the measurements and / or other information related to channel quality may differ compared to HD communication. To properly configure the UE and BS, for FD communication, information related to channel quality applicable to FD communication can be used.

[0010] However, obtaining such information can be difficult and / or time-consuming. Therefore, when the BS and UE are using FD communication, it is necessary to obtain measurements and / or other information related to channel quality.

[0011] In light of the foregoing, this disclosure describes various systems, devices, apparatuses, methods, and computer programs (e.g., encoded on a storage medium and / or configured with at least one processor) for a UE configured to perform FD communications to determine channel measurements and report associated information. UL signals, such as sounding reference signals (SRS), control information within a scheduled physical uplink control channel (PUCCH), data and / or other uplink signals within a scheduled physical uplink shared channel (PUSCH), can be transmitted from the UE to the BS in UL resources. Simultaneously with transmitting UL signals in UL resources, the UE can determine channel quality information in DL resources configured by the BS. This channel quality information may include, for example, at least one of the following: measurements of energy and / or signal strength, values ​​indicating channel quality, channel state information (CSI), and other such information / values.

[0012] For example, while receiving DL signals from BS in DL resources, the UE can transmit UL signals in UL resources; for example, the DL signals may include CSI-RS. In another example, while detecting or measuring energy or interference in DL resources, the UE can transmit UL signals in UL resources; for example, DL resources may include CSI Interference Measurement (IM) resources (which can be configured by the BS for the UE). Therefore, the UE can determine channel quality information in DL resources configured by the BS while simultaneously transmitting UL signals in UL resources.

[0013] In some respects, DL resources may be adjacent to or at least partially overlap with UL resources. For example, UL resources and DL resources may be sub-band frequency division duplex (FDD) resources (also known as flexible FDD) or in-band full-duplex (IBFD) resources.

[0014] In practice, the UE can determine at least one channel measurement and / or channel quality in the presence of UL transmissions, for example, by making the UL transmissions act as interference against the DL resources. Based on the DL signal, the UE can measure and / or determine at least one value or other information indicating channel quality, where channel quality may include values ​​and / or information related to signal strength, signal quality, interference measurements, CSI, etc. Specifically, the UE can generate a Channel State Feedback (CSF), which may include measurements and / or information associated with channel quality. For example, the CSF may include at least one of the following: Channel Quality Indicator (CQI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), CSI, and / or other values ​​or information associated with the quality of the channel between the UE and the BS. The UE can then send information to the BS based on the determined channel quality; specifically, the sent information may include the CSF.

[0015] In a first aspect of this disclosure, a first method, a first computer-readable medium, and a first apparatus for wireless communication are provided. The first apparatus may be a UE or a wireless device at the UE. The first apparatus may transmit UL signals from a UL resource set configured by a BS. The first apparatus may further monitor a DL resource set configured by the BS, which is adjacent to or at least partially overlaps with the UL resource set. The first apparatus may determine the channel quality associated with the DL resource set based on the UL signals transmitted in the UL resource set. Additionally, the first apparatus may transmit information to the BS indicating a CSF based on the determined channel quality.

[0016] In a second aspect of this disclosure, a second method, a second computer-readable medium, and a second apparatus for wireless communication are provided. The second apparatus may be a BS or a wireless device at the BS. The second apparatus may configure a DL resource set associated with a CSI for a UE, the DL resource set being adjacent to or at least partially overlapping with a UL resource set. The second apparatus may further receive information from the UE indicating a CSF based on the DL resource set. The second apparatus may then configure FD communication with the UE based on the information indicating the CSF.

[0017] In a third aspect of this disclosure, a third method, a third computer-readable medium, and a third apparatus for wireless communication are provided. The third apparatus may be a UE or a wireless device at the UE. The third apparatus may determine that a UL transmission to a first BS will occur simultaneously with a DL reception, wherein at least one of a Radio Link Monitoring (RLM) measurement or a Radio Resource Management (RRM) measurement will be performed with respect to the DL reception. In this case, the third apparatus may avoid transmitting a UL signal to the first BS while simultaneously receiving a DL signal in the DL. When performing at least one of an RLM measurement or an RRM measurement based on the received DL signal, the third apparatus may further transmit a report indicating at least one of the RLM measurement results or RRM measurement results.

[0036] The specific embodiments described below with reference to the accompanying drawings are intended merely to describe various configurations and not to indicate that the concepts described herein can be implemented only in these configurations. Specific details are included in the specific embodiments to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be implemented without using these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0037] Various apparatuses and methods are now described with reference to some aspects of a telecommunications system. These apparatuses and methods will be described in the following detailed embodiments and depicted in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements”). Such elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0038] For example, an element, any part of an element, or any combination of elements can be implemented as a "processing system" including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in a processing system can execute software. Software should be broadly interpreted as meaning instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc., regardless of whether it is referred to as software, firmware, middleware, microcode, hardware description languages, or other terms.

[0039] Therefore, in one or more exemplary embodiments, the functions described herein can be implemented in hardware, software, or any combination thereof. When implemented in software, these functions can be stored or encoded as one or more instructions or code on a computer-readable medium. A computer-readable medium includes a computer storage medium. The storage medium can be any available medium accessible to a computer. By way of example, and not limitation, such a computer-readable medium can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of computer-readable media of the foregoing types, or any other medium capable of storing computer-executable code in the form of instructions or data structures and accessible to a computer.

[0040] Figure 1 This diagram illustrates an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a Wireless Wide Area Network (WWAN)) includes a base station (BS) 102, a user interface (UE) 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). The BS 102 may include macro cells (high-power cellular BSs) and / or small cells (low-power cellular BSs). Macro cells include BSs. Small cells include femtocells, picocells, and microcells.

[0041] The BS 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interact with the EPC 160 via a first backhaul link 132 (e.g., the S1 interface). The BS 102 configured for 5G NR (collectively referred to as the Next Generation RAN (NG-RAN)) can interact with the core network 190 via a second backhaul link 184. Among other functions, the BS 102 can perform one or more of the following functions: user data transmission, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of Non-Access Stratum (NAS) messages, NAS node selection, synchronization, Radio Access Network (RAN) sharing, Multimedia Broadcast Multicast Service (MBMS), user and equipment tracking, RAN Information Management (RIM), paging, location, and alarm message delivery. BS 102 can communicate directly or indirectly with each other via backhaul link 134 (e.g., X2 interface) (e.g., via EPC 160 or core network 190). The third backhaul link 134 can be wired or wireless.

[0042] BS 102 can communicate wirelessly with UE 104. Each of BS 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro BS 102. A network including small cells and macro cells can be referred to as a heterogeneous network. In addition, a heterogeneous network may also include home node B (eNB) (HeNB), which can provide services to a restricted group called a closed subscriber group (CSG). The communication link 120 between BS 102 and UE 104 may include uplink (UL) (also referred to as reverse link) transmission from UE 104 to BS 102 and / or downlink (DL) (also referred to as forward link) transmission from BS 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technology, which includes spatial multiplexing, beamforming, and / or transmit diversity. These communication links may be via one or more carriers. The BS102 / UE 104 may use up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) of bandwidth for each carrier allocated in carrier aggregation for transmissions in each direction, totaling up to Yx MHz (x component carriers). These carriers may be adjacent to each other or not. Carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). These component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carriers may be referred to as secondary cells (SCells).

[0043] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL WWAN spectrum. D2D communication link 158 can use one or more side link channels, such as Physical Side Link Broadcast Channel (PSBCH), Physical Side Link Discovery Channel (PSDCH), Physical Side Link Shared Channel (PSSCH), and Physical Side Link Control Channel (PSCCH). D2D communication can be performed through various wireless D2D communication systems, such as FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0044] The wireless communication system may also include a Wi-Fi access point (AP) 150, which communicates with a Wi-Fi station (STA) 152 via a communication link 154 in the 5 GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.

[0045] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and use the same 5 GHz unlicensed spectrum as Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can improve access network coverage and / or increase access network capacity.

[0046] BS 102 (whether it's a small cell 102' or a large cell (e.g., a macro BS)) may include and / or be referred to as an eNB, gNodeB (gNB), or another type of BS. Some BSs, such as gNB 180, can operate in the conventional sub-6 GHz spectrum at millimeter wave (mmW) frequencies and / or near-mmW frequencies to communicate with UE 104. When gNB 180 operates at mmW or near-mmW frequencies, gNB 180 may be referred to as an mmW BS. Extremely high frequency (EHF) is a portion of the radio frequency (RF) spectrum within the electromagnetic spectrum. EHF has a range from 30 GHz to 300 GHz, with wavelengths between 1 mm and 10 mm. Radio waveforms in this band may be referred to as millimeter waves. Near-mmW can extend down to frequencies of 3 GHz with wavelengths of 100 mm. Ultra-high frequency (SHF) bands extend between 3 GHz and 30 GHz, and are also referred to as centimeter waves. Communication using mmW / near mmW radio bands (e.g., 3 GHz–300 GHz) suffers from extremely high path loss and short range. The mmW BS 180 can compensate for this high path loss and short range by utilizing beamforming 182 with the UE 104. Both the BS 180 and the UE 104 can each include multiple antennas (e.g., antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming.

[0047] BS 180 can transmit 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 transmit beamformed signals to BS 180 in one or more transmit directions. BS 180 can receive beamformed signals from UE 104 in one or more receive directions. BS 180 / UE 104 can perform beam training to determine the optimal receive and transmit directions for each of BS 180 / UE 104. The transmit and receive directions of BS 180 can be the same or different. The transmit and receive directions of UE 104 can be the same or different.

[0048] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 can communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets can be transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), and Packet Switched (PS) streaming services and / or other IP services. The BM-SC170 provides functions for MBMS user service provisioning and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, authorize and initiate MBMS bearer services in the Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS Gateway 168 can distribute MBMS services to BS 102 belonging to the Broadcast-Specific Service Single Frequency Network (MBSFN) area, and can be responsible for session management (start / stop) and collecting billing information related to eMBMS.

[0049] The core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and the core network 190. Typically, AMF 192 provides QoS streaming and session management. All user Internet Protocol (IP) packets can be transmitted via UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP service 176. IP service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services.

[0050] A BS may include and / or be referred to as a gNB, Node B, eNB, access point, base transceiver, radio BS, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), transport receiving point (TRP), or some other suitable term. BS 102 provides UE 104 with an access point for EPC 160 or core network 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, meters, air pumps, large or small kitchen appliances, medical devices, implants, sensors / actuators, displays, or any other similar functional devices. Some of UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, user station, mobile unit, user unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile user station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or any other suitable term.

[0051] While this disclosure focuses on 5G NR, the concepts and aspects described herein can be applied to other similar fields, such as LTE, LTE-A Advanced, Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), or other wireless / radio access technologies.

[0052] Reference again Figure 1In some respects, BS 102 / 180 can configure a set of DL resources and / or a set of UL resources for UE 104. For example, it can configure the bandwidth for UE 104 to communicate with BS 102 / 180. This bandwidth can be configured for full-duplex (FD) communication. FD communication is a wireless communication method that supports simultaneous transmission and reception of information on the same frequency band. In this way, spectral efficiency can be improved compared to half-duplex (HD) communication, where HD communication supports information transmission / reception in only one direction at a time.

[0053] For example, bandwidth can be configured for in-band FD (IBFD) operation, where uplink and downlink resources share the same IBFD time / frequency resources (e.g., UL resources may partially or completely overlap with DL resources). Therefore, UE104 and BS102 / 180 can each transmit and receive on that time / frequency resource.

[0054] In another example, bandwidth can be configured for flexible duplex or flexible frequency division duplex (FDD) (which can also be called subband FDD). With flexible FDD, uplink and downlink resources share the same time resources (e.g., UL resources may completely overlap with DL resources in the time domain) but are adjacent in the frequency domain. That is, uplink and downlink resources do not need to overlap in the frequency domain; instead, they can be configured to be adjacent, for example, separated by guard bands, making them discontinuous in the frequency domain. Therefore, UE104 and BS 102 / 180 can each transmit and receive on different time resources but on different frequency resources.

[0055] In various aspects, BS 102 / 180 can configure a DL resource set associated with Channel State Information (CSI) for UE 104. This DL resource set is configured with a UL resource set for IBFD or Flexible FDD operation. For example, the DL resource set may at least partially overlap with the UL resource set in the time domain, and the DL resource set may be adjacent to or at least partially overlap with a set of UL resources in the frequency domain.

[0056] UE 104 can be configured to transmit UL signals, for example, to BS 102 / 180 within UL resources. In some cases, BS 102 / 180 can receive UL signals from UE 104 within UL resources. UE 104 can further monitor DL ​​resource sets (e.g., configured by BS 102 / 180). Since UL and DL resources can overlap at least partially in time, UL signals can also overlap with DL resource sets in time.

[0057] Then, UE 104 can determine the channel quality associated with the DL resource set based on the UL signals transmitted in the UL resource set. In one aspect, BS 102 / 180 can configure the DL resource set as a CSI interference measurement (IM) resource, so UE 104 can determine the channel quality by measuring the energy (e.g., interference or other signal strength) in the CSI-IM resource (i.e., the DL resource set in this respect).

[0058] On another front, BS 102 / 180 may transmit at least one CSI reference signal (RS) in the DL resource set. Therefore, UE 104 may receive at least one CSI-RS and determine channel quality (e.g., CSI or other channel quality information / values) based on the received CSI-RS. Since at least one CSI-RS may be received in a DL resource set that overlaps at least temporally with the UL resources transmitting the UL signal, the channel quality determined by UE 104 may be affected by the UL signals in the UL resource set (e.g., interference).

[0059] Subsequently, UE 104 can determine the Channel State Feedback (CSF) based on the channel quality associated with the DL resource set, wherein the channel quality is determined based on UL signals transmitted in UL resource sets adjacent to or at least partially overlapping with the DL resource set (198). UE 104 can then send information indicating the CSF to BS 102 / 180 based on the determined channel quality.

[0060] Accordingly, BS 102 / 180 can receive information indicating CSF from UE 104, wherein the CSF is based on the channel quality associated with the DL resource set, which is determined based on UL signals transmitted in UL resource sets that are adjacent to or at least partially overlap with the DL resource set (198).

[0061] This document further describes various aspects and other details related to FD communication between the UE and BS based on the CSF determined by the UE.

[0062] Figure 2A Figure 200 shows an example of the first subframe in a 5G / NR frame structure. Figure 2B Figure 230 shows an example of a DL channel in a 5G / NR subframe. Figure 2C Figure 250 shows an example of the second subframe in a 5G / NR frame structure. Figure 2DFigure 280 illustrates an example of a UL channel in a 5G / NR subframe. This 5G / NR frame structure can be FDD or Time Division Duplex (TDD). In the FDD case, for a specific set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to either DL or UL. In the TDD case, for a specific set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to both DL and UL. Figure 2A , 2C In the provided examples, the 5G / NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (primarily DL), where D is DL, U is UL, and X is used flexibly between DL and UL, and subframe 3 is configured with slot format 34 (mostly UL). Although subframes 3 and 4 are shown with slot formats 34 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are full DL and UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The slot format is configured for the UE via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-static / static configured via Radio Resource Control (RRC) signaling). It should be noted that the following description also applies to TDD 5G / NR frame structures.

[0063] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 subframes (1 ms) of the same size. Each subframe may include one or more time slots. Subframes may also include micro-slots, which may include 7, 4, or 2 symbols. Depending on the time slot configuration, each time slot may include 7 or 14 symbols. For time slot configuration 0, each time slot may include 14 symbols, while for time slot configuration 1, each time slot may include 7 symbols. Symbols on the DL can be Cyclic Prefix (CP) OFDM (CP-OFDM) symbols. Symbols on the UL can be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the time slot configuration and digital scheme. For slot configuration 0, different digital schemes μ0 to 5 allow each subframe to have 1, 2, 4, 8, 16, and 32 slots, respectively. For slot configuration 1, different digital schemes 0 to 2 allow each subframe to have 2, 4, and 8 slots, respectively. Therefore, for slot configuration 0 and digital scheme μ, there are 14 symbols / slots and 2μ slots / subframes. The subcarrier spacing and symbol length / duration depend on the digital scheme. The subcarrier spacing can be equal to 2. μ*15kHz, where μ is the digital scheme from 0 to 5. Thus, the subcarrier spacing is 15kHz for digital scheme μ=0 and 480kHz for digital scheme μ=5. The symbol length / duration is inversely proportional to the subcarrier spacing. Figure 2A-2D Examples are provided for slot configuration 0 with 14 symbols per slot and digital scheme μ=0 with 1 slot per subframe. The subcarrier spacing is 15 kHz and the symbol duration is approximately 66.7 μs.

[0064] The frame structure is represented using a resource grid. Each time slot consists of a resource block (RB) extending for 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0065] like Figure 2A As shown, some of the REs carry reference (pilot) signals (RS) for the UE. These RSs may include a demodulation RS (DM-RS) (indicated as RX for a particular configuration, where 100x is the port number, but other DM-RS configurations are also possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RSs may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).

[0066] Figure 2B Examples of various DL channels in a subframe of a frame are shown. The Physical Downlink Control Channel (PDCCH) carries the DCI in one or more Control Channel Elements (CCEs), each CCE comprising nine RE Groups (REGs), each REG comprising four consecutive REs in an OFDM symbol. The Primary Synchronization Signal (PSS) may be located in symbol 2 of a specific subframe of the frame. UE 104 uses the PSS to determine subframe / symbol timing and physical layer identifiers. The Secondary Synchronization Signal (SSS) may be located in symbol 4 of a specific subframe of the frame. The UE uses the SSS to determine the Physical Layer Cell Identifier Group Number and radio frame timing. Based on the Physical Layer Identifier and 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 DM-RS. The Physical Broadcast Channel (PBCH) carrying the Primary Information Block (MIB) can be logically combined 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)) that is not transmitted via the PBCH, and paging messages.

[0067] like Figure 2CAs shown, some REs carry DM-RS (indicated as R for a specific configuration, but other DMRS configurations are also possible) for channel estimation at the BS. The UE can transmit DM-RS for PUCCH and DM-RS for PUSCH. PUSCH DM-RS can be transmitted in the first one or two symbols before the PUSCH. PUCCH DM-RS can be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and the specific PUCCH format used. The UE can transmit SRS. SRS can be transmitted in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of the comb structures. The BS can use SRS for channel quality estimation to implement frequency-dependent scheduling on the UL.

[0068] Figure 2D Examples of various UL channels in a subframe of a frame are shown. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI) such as scheduling requests, CQI, PMI, RI, and Hybrid Automatic Repeat Request (HARQ) ACK / NACK feedback. The PUSCH carries data, and can also be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI.

[0069] Figure 3This is a block diagram illustrating the communication between BS 310 and UE 350 in the access network. In the DL, IP packets from EPC 160 are provided to the controller / processor 375. The controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Serving Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides: RRC layer functions associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), movement between radio access technologies (RATs), and measurement configuration for UE measurement reporting; PDCP layer functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with upper-layer packet data unit (PDU) transmission, error correction via ARQ, connection, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing MAC SDUs onto transport blocks (TBs), demultiplexing MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority allocation.

[0070] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection of the transport channel, forward error correction (FEC) encoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping for the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase phase shift keying (M-PSK), and M-order quadrature amplitude modulation (M-QAM)). The encoded and modulated symbols can then be segmented into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently combined using an inverse Fourier transform (IFFT) to generate a physical channel carrying a stream of time-domain OFDM symbols. The OFDM stream is spatially precoded to generate multiple spatial streams. Channel estimates from channel estimator 374 can be used to determine coding and modulation schemes and to implement spatial processing. The channel estimates can be derived from reference signals and / or channel condition feedback transmitted by UE 350. Subsequently, each spatial stream can be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can use the respective spatial stream to modulate an RF carrier for transmission.

[0071] At UE 350, each receiver 354RX receives signals through its respective antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides this information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial streams destined for UE 350. If multiple spatial streams are destined for UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. Subsequently, the RX processor 356 uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, along with the reference signal, are recovered and demodulated by determining the most probable signal constellation points transmitted by BS 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. These soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted by BS 310 on the physical channel. This data and control signals are then provided to controller / processor 359, which implements Layer 3 and Layer 2 functions.

[0072] The controller / processor 359 can be associated with a memory 360 that stores program code and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0073] Similar to the functions described in the DL transmission combined with BS 310, controller / processor 359 provides: RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with upper-layer PDU transmission, error correction via ARQ, RLC SDU connection, segmentation and reassembly, RLC data PDU resegmentation, and RLC data PDU reordering; and MAC layer functions associated with mapping between logical channels and transport channels, MAC SDU multiplexing onto TB, demultiplexing MAC SDU from TB, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority allocation.

[0074] The channel estimate derived by channel estimator 358 from the reference signal or feedback transmitted by BS 310 can be used by TX processor 368 to select appropriate coding and modulation schemes and facilitate spatial processing. The spatial stream generated by TX processor 368 can be provided to different antennas 352 via their respective transmitters 354TX. Each transmitter 354TX can use its own spatial stream to modulate the RF carrier for transmission.

[0075] In a manner similar to that described in conjunction with the receiver function at UE 350, BS 310 processes the UL transmission. Each receiver 318RX receives the signal via its respective antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides that information to the RX processor 370.

[0076] The controller / processor 375 can be associated with a memory 376 that stores program code and data. The memory 376 can be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets from the UE 350. IP packets from the controller / processor 375 can be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0077] In some respects, at least one of the TX processor 368, the RX processor 356, and the controller / processor 359 can be configured to perform actions related to... Figure 1 (198) related aspects.

[0078] In some other respects, at least one of the TX processor 316, the RX processor 370, and the controller / processor 375 can be configured to perform operations related to... Figure 1 (198) related aspects.

[0079] See Figure 4 to Figure 14 This describes various aspects related to determining, transmitting, and applying the CSF (Content Filtering) for FD (Digital Frequency) communication. FD is a wireless communication method that supports simultaneous transmission and reception of information in the same frequency band. In this way, spectral efficiency can be improved compared to half-duplex (HD) communication, which supports information transmission / reception in only one direction at a time.

[0080] Given the concurrent or simultaneous nature of FD communication, transmitting UL signals from the UE concurrently with receiving DL signals from the BS can affect channel quality, especially on the channel between the BS and the UE. For example, uplink communication from the UE to the BS may degrade downlink communication from the BS to the UE (e.g., by introducing interference), and vice versa.

[0081] Therefore, for example, when the BS and UE use FD communication, the channel quality-related measurements and / or other information may differ compared to HD communication. To properly configure the UE and BS, for FD communication, channel quality-related information applicable to FD communication can be used.

[0082] However, obtaining such information can be difficult and / or time-consuming. Therefore, when the BS and UE are using FD communication, it is necessary to obtain measurements and / or other information related to channel quality.

[0083] In light of the foregoing, this disclosure describes various systems, devices, apparatuses, methods, and computer programs (e.g., encoded on a storage medium and / or configured with at least one processor) for a UE configured to perform FD communications to determine channel measurements and report associated information. UL signals, such as SRS, control information within a scheduled PUCCH, data within a scheduled PUSCH, and / or other uplink signals, can be transmitted from the UE to the BS in UL resources. Simultaneously with transmitting UL signals in UL resources, the UE can determine channel quality information in DL resources configured by the BS. This channel quality information may include, for example, at least one of the following: measurements of energy and / or signal strength, values ​​indicating channel quality, CSI, and other such information / values.

[0084] For example, while receiving DL signals from DL resources from the BS, the UE can transmit UL signals in UL resources; for example, the DL signals may include CSI-RS. In another example, while detecting or measuring energy or interference in DL resources, the UE can transmit UL signals in UL resources; for example, the DL resources may include CSI-IM resources (which can be configured by the BS for the UE). Therefore, the UE can determine channel quality information in DL resources configured by the BS while simultaneously transmitting UL signals in UL resources.

[0085] In some respects, DL resources may be adjacent to or at least partially overlap with UL resources. For example, UL and DL resources may be FD resources (e.g., flexible FDD resources or IBFD resources). For IBFD, UL resources may at least partially overlap with DL resources in the frequency domain. That is, at least some of the UL and DL resources may be configured on the same spectrum (e.g., because at least some subcarriers may be shared by UL and DL resources).

[0086] However, for flexible FDD, UL resources can be adjacent to DL resources in the frequency domain. In other words, UL resources can be configured on a different spectrum than DL resources (e.g., UL resources may not share subcarriers with DL resources). Potentially, a guard band can be configured between UL and DL resources; for example, the guard band may include a portion of the spectrum not used by either UL or DL ​​resources.

[0087] FD resources can overlap at least partially in time, regardless of whether the UL and DL resources are flexible FDD or IBFD. Therefore, UL signals in UL resources that at least partially overlap with DL resources can be concurrent or simultaneous with DL signals in those DL resources.

[0088] As used in the context of resources and / or communications in this disclosure, "concurrent" or "simultaneous" may refer to resources that at least partially overlap in time. Illustratively, when one or more UL resources carrying UL signals overlap at least partially in time with one or more DL resources carrying DL signals, the UL signals in the UL resources may occur concurrently with the DL signals in the DL resources, even if the time boundaries of the UL and DL resources are not synchronized or aligned. For example, a UL symbol may appear at the same point in time as a DL symbol, and therefore the UL signals in the UL symbol may occur concurrently or simultaneously with the DL signals in the DL symbol.

[0089] In practice, the UE can determine at least one channel measurement and / or channel quality in the DL resource in the presence of UL transmissions (e.g., such that the UL transmissions act as interference to the DL resource). Based on the DL signal, the UE can measure and / or determine at least one value or other information indicating channel quality, which may include values ​​and / or information related to signal strength, signal quality, interference measurements, CSI, etc. Specifically, the UE can generate a CSF, which may include measurements and / or information associated with channel quality. For example, the CSF may include at least one of the following: CQI, RI, PMI, CSI, and / or other values ​​or information associated with channel quality between the UE and the BS. The UE can then transmit information to the BS based on the determined channel quality; specifically, the transmitted information may include the CSF.

[0090] In some aspects, the CSF may be based on (e.g., may include) CSI. However, CSI may be determined (e.g., calculated, measured, etc.) at the receiver side (e.g., at the UE). Therefore, the CSF may include mechanisms for transmitting channel quality, channel characteristics, and / or other relevant information observed at the receiver side to the transmitter side (e.g., BS). Thus, the CSF may include CSI, such as PMI, RI, and / or CQI, and / or the CSF may include CSI applicable to the transmitter side.

[0091] Figures 4A-4CVarious modes of FD communication are illustrated. FD communication is a wireless communication method that supports simultaneous transmission and reception of information in the same frequency band. In this way, spectral efficiency can be improved relative to HD communication, which only supports transmission or reception in one direction at a time. Due to the simultaneous TX / RX characteristics of FD communication, the UE or BS may experience self-interference caused by signal leakage from its local transmitter to its local receiver. Furthermore, the UE or BS may also be subject to interference from other devices, such as transmissions from a second UE or second BS. Such interference (e.g., self-interference or interference caused by other devices) may affect the quality of information transmitted via signal transmission and may even lead to information loss.

[0092] Figure 4A A first configuration 400 is shown in which a first BS 402a communicates with a first UE 404a and a second UE 406a. The first BS 402a is an FD BS, while the first UE 404a and the second UE 406a can be configured as HD UEs or FD UEs. The second UE 406a can transmit a first signal in UL resources to the first BS 402a and other BSs (e.g., a second BS 408a located near the second UE 406a). The first BS 402a and the second BS 408a can be configured as an eNB, gNB, mmW BS, small cell, and / or another BS.

[0093] exist Figure 4A In this configuration, the first BS 402a transmits a second signal to the first UE 404a in the DL resource, while simultaneously receiving a first signal from the second UE 406a in the UL resource. Therefore, due to the simultaneous transmission of the second and first signals, self-interference may occur at the first BS 402a. Further interference may occur at the first BS 402a via signals transmitted from the second BS 408a. Interference may also occur at the first UE 404a based on such signals transmitted from the second BS 408a and UE-based signals transmitted from the second UE 406a.

[0094] Figure 4BA second configuration 410 is shown in which the first BS 402b communicates with the first UE 404b. The first BS 402b is an FD BS and the first UE 404b is an FD UE. That is, the first BS 402b can simultaneously transmit a second signal to the first UE 404b in DL resources and receive a first signal from the first UE 404b in UL resources; and the first UE 404b can simultaneously transmit a first signal to the first BS 402b in UL resources and receive a second signal from the first BS 402b in DL resources. Therefore, since the first signal and the second signal are transmitted simultaneously between the first BS 402b and the first UE 404b, self-interference may occur at either or both of the first BS 402b and / or the first UE 404b. Further interference may also occur at the first UE 404b based on one or more signals transmitted from the second UE 406b and / or the second BS 408b, which is close to the first UE 404b. The first BS 402b and the second BS 408b can be configured as eNB or gNB.

[0095] Figure 4C A third configuration 420 is shown in which the first UE 404c communicates with the first BS 402c and the second BS 408c. The first UE 404c is an FD UE, where the first BS 402c and the second BS 408c serve as multiple transmit and receive points (multiple TRPs) for UL and DL resources. In one example, the second BS 408c can communicate with the second UE 406c and send additional DL resources to it. Figure 4C In this configuration, the first UE 404c is configured to simultaneously receive a second signal from the second BS 408c in the DL resource and transmit a first signal to the first BS 402c in the UL resource. Therefore, due to the simultaneous transmission of the first and second signals, self-interference may occur at the first UE 404c. Further interference may also occur at the first UE 404c via UE-based signals transmitted from the second UE 406c.

[0096] Figures 5A-5B First example 500 and second example 510 are shown as resources for IBFD. Generally, FD operations can be divided into two categories: (1) IBFD operations and (2) subband FDD (or flexible FDD) operations. In IBFD, the transmitted signal (e.g., UL signal) and the received signal (e.g., DL signal) overlap at least partially in time and frequency.

[0097] As shown in the first example 500, the time and frequency allocation of the UL band (e.g., including UL resource 502) can completely overlap with the frequency allocation of the DL band (shown as DL resource 504). Furthermore, UL resource 502 can completely overlap with DL resource 504 in time. For illustration, UL resource 502 can be a subset of DL resource 504, for example, such that any UL signal on UL resource 502 has the possibility of being at the same time and frequency as a DL signal on DL resource 504 (although the reverse is not necessarily true, since DL resource 504 can span a longer duration and / or more number of subcarriers than UL resource 502).

[0098] In the second example 510 of IBDD, the frequency allocation of the UL band (shown as UL resource 512) may partially overlap with the allocated frequency of the DL band (shown as DL resource 514). However, UL resource 512 may completely overlap with DL resource 514 in time.

[0099] IBFD communication (e.g., as Figure 5A and Figure 5B Examples 500 and 510 show one implementation of FD operation, while flexible or subband FDD is another (but different) implementation of FD operation. In some implementations of subband FDD, different frequencies are used to transmit and receive in the UL and DL bands (but still transmit and receive simultaneously).

[0100] For example, for subband FDD operation, the DL band can be separated from the UL band in the frequency domain. For instance, a guard band comprising a set of subcarriers can separate the UL and DL bands, or the UL and DL bands can be continuous in the frequency domain (e.g., making the guard band zero subcarriers). Given that the output signal from the UE transmitter may have leakage extending beyond the UL band, a guard band of a certain width may be beneficial in reducing interference between UL and DL resources. Subband FDD can also be referred to as "flexible duplex."

[0101] Figure 6 This is a call flowchart 600 illustrating the communication between UE 604 and BS 602. For example, refer to... Figure 1 , 3 As shown in Figure 4, UE 604 can be implemented as one of UE 104, UE 350 and / or UE 404a-c, 406a-c, while BS 602 can be implemented as one of BS102 / 180, BS 310 and / or BS 402a-c, 408a-c.

[0102] BS 602 can configure DL resource 608 for UE 604. In some aspects, DL resource 608 can be associated with CSI; for example, DL resource 608 can be a resource that schedules BS 602 to transmit CSI-RS, or DL ​​resource 608 can be a resource reserved for CSI-IM, and therefore DL signals may not be carried in DL resource 608. To configure UE 604, BS 602 can send information to UE 604 indicating the allocation of DL resource 608. This information indicating the allocation of DL resource 608 can further indicate that DL resource 608 is associated with CSI-RS or CSI-IM (e.g., reserved for CSI-RS or CSI-IM).

[0103] In some respects, UE 604 may transmit UL signal 607 to BS 602 in UL resource 606. UL signal 607 may be SRS, DM-RS, PT-RS, data (on PUSCH), or control information (on PUCCH). UL signal 607 may be any UL transmission capable of performing DL channel measurements on it, and may be any UL transmission that allows the UE to transmit in IBFD and / or flexible FDD modes.

[0104] UE 604 can monitor DL ​​resource 608 simultaneously (in time) with the transmission of UL signals. DL resource 608 may be adjacent to UL resource 606 in the frequency domain (e.g., for flexible FDD) or at least partially overlap (e.g., for IBFD). However, DL resource 608 may at least partially overlap with UL resource 606 (e.g., concurrently or simultaneously).

[0105] In some respects, UE 604 can monitor DL ​​resource 608 as a CSI-IM resource. A CSI-IM resource can be a resource on which BS 602 does not schedule any DL signaling. Conversely, a CSI-IM resource can be a resource on which UE 604 is able to measure energy and / or signal strength. Since BS 602 can avoid transmitting during the CSI-IM resource period, the energy and / or signal strength measured by UE 604 on it can indicate potential interference (e.g., interference from neighboring BSs and / or other UEs).

[0106] In some other aspects, UE 604 may monitor DL ​​resource 608 to detect and / or receive at least one CSI-RS 609. UE 604 may measure and / or determine values ​​and / or other information based on receiving at least one CSI-RS 609. For example, UE 604 may measure or determine one or more of the following measurements based on at least one CSI-RS 609: Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), Signal-to-Noise Ratio (SNR), Signal-to-Interference Plus Noise Ratio (SINR), and / or other measurements.

[0107] UE 604 may determine the channel quality associated with DL resource 608 based on the UL signal 607 transmitted in UL resource set 606. Potentially, UE 604 transmitting the UL signal 607 in UL resource 606 may self-interfere with DL resource 608.

[0108] Since UL signal 607 may introduce interference to DL resource 608, UE 604 can determine (610) how UL signal 607 affects (e.g., interferes with) DL resource 608. For example, channel quality may be based on energy measured on DL resource 608 (e.g., when DL resource 608 is configured as a CSI-IM resource) and / or channel quality may be based on RSRP, SNR, or other values ​​measured according to at least one CSI-RS 609 in DL resource 608.

[0109] In some aspects, channel quality determination 610 may include the determination of CSI. For example, UE 604 may determine one or more of RI, PMI, CQI, and / or other CSIs based on interference caused by UL signal 607 in UL resource 606 in DL resource 608. In some aspects, UE 604 may determine one or more of RI, PMI, CQI, and / or other CSIs for broadband bandwidth. In some other aspects, UE 604 may determine one or more of RI, PMI, CQI, and / or other CSIs for each of a plurality of subbands, for example, DL resource 608.

[0110] Potentially, CSI can be associated with reporting frequencies such as periodic, semi-persistent, or aperiodic. In some respects, UE 604 can generate (612) CSF 616 based on the periodicity of CSI. For example, a single CSF report can be generated when CSI is periodic, or multiple CSF reports can be generated on a semi-persistent or aperiodic basis when CSI is not periodic.

[0111] In some other respects, UE 604 can also determine (614) the average CQI value based on previous CSI. For example, UE 604 can measure or determine the channel quality or CQI over the entire DL band and can calculate the average quality or CQI over the DL band.

[0112] Then, UE 604 may send CSF 616 to BS 602 based on the determined channel quality. CSF 616 may include one or more of RI, PMI, CQI and / or other CSIs. CSF 616 may indicate interference to DL resource 608 caused by UL signal 607 on UL resource 606.

[0113] In some respects, UE 604 may further transmit a second CSF to BS 602 based on the determined second channel quality, wherein the second channel quality is determined based on a second UL signal. The second UL signal may be similar to UL signal 607; however, it may be transmitted to BS 602 based on a different configuration than UL signal 607 (e.g., different transmit power, different UL bandwidth, and / or different waveform) to provide different measurement characteristics. Furthermore, if the second DL signal is received non-simultaneously with any UL transmission, UE 604 may send an indication to BS 602 that the second channel quality was determined in the absence of concurrent UL transmissions.

[0114] In some further aspects, UE 604 may, for example, perform (620) at least one radio link monitoring (RLM) and / or radio resource management (RRM) measurement based on monitoring a DL resource (e.g., DL resource 608), wherein the DL resource may be (virtually) adjacent to a UL resource (e.g., DL resource 608 and UL resource 606 may be separated by a guard band). For example, UE 604 may measure RSRP and / or RSRQ based on at least one DL signal received from BS 602 in the DL resource (e.g., at least one CSI-RS 609 in DL resource set 608). In another example, UE 604 may measure RSRP and / or RSRQ based on at least one other DL signal received from another BS adjacent to BS 602. In some aspects, when UE 604 performs (620) RLM and / or RRM measurement 622, UE 604 may avoid the transmission of any UL signal. In some other respects, UE604 can simultaneously send at least one UL signal with the execution 620 of RLM and / or RRM measurement 622.

[0115] UE 604 may send a report to BS 602 indicating RLM and / or RRM measurements 622. Potentially, UE 604 may send information 624 to BS 602 indicating that the RLM and / or RRM measurements 622 associated with the report sent to BS 602 were performed while UE 604 was in HD mode. Information 624 may be included in the same or different transmissions as the report indicating RLM and / or RRM measurements 622.

[0116] Figure 7 This is a call flow diagram 700 illustrating communication between UE 702 and at least one BS (e.g., first BS 704 and second BS 706). UE 702 may determine (708) to send a UL signal 714 to the first BS 704 simultaneously with DL resource 716, wherein at least one RLM and / or RRM measurement will be performed on DL resource 716.

[0117] UE 702 can prevent (710) the transmission of UL signal 714 to the first BS 704 while simultaneously monitoring DL resource 716, for example by discarding UL signal 714 that would be transmitted simultaneously with DL resource 716. Alternatively, UE 702 can receive HD mode configuration 712 from the second BS 706, which instructs UE 702 to perform RLM and / or RRM measurements in HD mode. The second BS 706 can be the same BS as the first BS 704 or a different BS than the first BS 704.

[0118] Then, UE 702 can perform (718) RLM and / or RRM measurements based on the received DL signal. For example, UE 702 can use RS (e.g., RSRP, RSSI, etc.) indicating whether the radio channel includes a link failure to perform RLM and / or RRM measurements 720. UE 702 can send a report indicating the result of RLM and / or RRM measurements 720. In some aspects, UE 702 can send information 722 indicating that the RLM and / or RRM measurements 720 associated with the report were performed in HD mode (based on HD mode configuration 712). HD mode information 722 can be incorporated into the same transmission as the transmission of RLM and / or RRM measurements 720, or in a separate transmission.

[0119] Figure 8 Interference threshold 806 related to UL resource 802 and DL resource 804 is shown. UE 604 is configured to measure interference for IBDD operation. Figures 5A-5B (as shown) or sub-band FDD operation ( Figure 8The FD UE (shown in the diagram) measures channel quality. That is, UE 604 is configured to measure channel quality even when UL transmissions and DL transmissions are in the same or adjacent frequency bands. In this case, different characteristics can be relied upon for channel measurement and channel quality determination compared to, for example, when UL and DL resources are sufficiently separated to avoid mutual interference. Therefore, channel measurement and channel quality determination can be performed for adjacent or overlapping frequency bands in the presence of UL transmissions that may cause interference. UE 604 can then report CSF to BS 602 based on the CSI-RS and / or CSI-IM received during the DL transmission. The CSI-IM may be different from the CSI-RS, or the CSI-IM may correspond to a specific type of CSI-RS.

[0120] In subband FDD, UL resource 802 may be directly adjacent to DL resource 804 (e.g., without a guard band in between) or close to DL resource 804 (e.g., separated by a guard band). The proximity of UL resource 802 to DL resource 804 may be based on an interference threshold 806, which indicates the leakage of signals received on the DL reception from the UL transmission that can be suppressed by UE 604. The interference threshold 806 may correspond to a monotonically decreasing function.

[0121] The impact of interference caused by UL transmissions on the DL channel can be measured through network configuration. In one aspect, CSI-RS can be scheduled in the DL band simultaneously with the transmission of UL signals in adjacent UL bands to measure the impact of UL transmission interference on the DL channel. For permitted UL transmissions, UE 604 can transmit PUSCH or PUCCH. Alternatively, UE 604 can transmit SRS in the UL band even without permission from BS 602. Channel measurements and reporting for UE 604 can be performed via different configurations of UL signals with different adjacent channel leakage rate (ACLR) characteristics. Various UL configurations can be based on the power, bandwidth, waveform, etc., of the UL signals. In particular, even if channel measurements and reporting have been performed for the first UL signal, changes in bandwidth, power, waveform, etc., may affect the interference observed on the DL caused by UL transmissions (e.g., the interference may be higher or lower).

[0122] When measuring the CSI-RS received in the DL signal, UE 604 can identify the CQI value and report it to BS 602. Based on the CQI value, the network can determine the channel quality. That is, UE 604 only measures the channel quality at different frequencies / RBs and reports the measured quality to BS 602. Leakage of the UL signal can have specific characteristics represented by an interference threshold 806 (e.g., the interference threshold monotonically decreases with increasing distance from the UL signal). Therefore, wideband and subband CQI values ​​can be identified and reported differently. To identify wideband CQI, UE 604 can send a single value to BS 602 indicating the average quality across the entire DL band. This contrasts with the identification of subband CQI, where UE 604 sends a value for any one of one or more specific frequency ranges within the DL band.

[0123] BS 602 can be configured to identify an ACLR profile (e.g., leakage performance) that is at least one of the following: independently measured and transmitted from UE 604, or based on auxiliary information (e.g., UE 604 can indicate to BS 602 what the ACLR profile looks like). BS 602 can also be configured to send a request to UE 604 to report CQI. As mentioned above, wideband CQI represents the average quality across the entire DL band. Since BS 602 is configured to identify ACLR profiles, BS 602 is also able to determine channel quality based on a comparison between the wideband CQI and the ACLR profile. For subband CQI, UE 604 can report CQI based on a fixed subband size or a variable subband size. Given that CQI values ​​typically vary little between locations close to UL resource 802, a fixed subband size may be required for CQI reporting at these locations. In contrast, a greater degree of variation may exist between CQI values ​​when the same bandwidth is located further away from UL resource 802. In this scenario, a variable subband size might be required to capture a wider area than that captured by a fixed subband size. This characteristic is represented by a sharp drop in the interference threshold 806, which supports using a smaller band size for RBs closer to UL resource 802 and a larger band size for RBs farther from UL resource 802.

[0124] Figures 9A-9BThe CQI offset table is described. For sub-band CQI reporting, UE 604 reports the average quality value for the entire frequency band and the offset level for each sub-band to BS 602. Sub-band CQI offset values ​​can be determined based on the generation of a new offset level table (e.g., Offset Table 900) or a modified offset level table (e.g., Offset Table 910). When representing interference from UL signals using a monotonically decreasing function, the average quality value will be higher near the maximum value of the curve. Therefore, negative offsets can be reported to BS 602 more frequently than positive offsets, where a "0" offset indicates that the sub-band includes the same CQI as the average CQI. Figure 9A In this context, a new offset table 900 is defined to maintain the same number of bits for CQI (e.g., providing 2 bits for 4 offset level options). Figure 9B In this context, the modified offset level table 910 is defined based on the increased number of bits (i.e., 3 bits providing 8 offset level options). Therefore, the modified offset level table 910 can provide a more accurate offset for CQI.

[0125] Given that CQI, RI, and PMI can all be transmitted in the CSF, UE 604 can be further configured to provide indications of different RIs or PMIs for different subbands. Specifically, UE 604 can report N RIs, L PMIs, and M subband CQIs, where N, L, and M do not necessarily represent the same number. In a first embodiment, reporting can be performed by having explicitly different codebook subset restrictions in different subbands (e.g., a single RI may correspond to a set of numbers of subbands, such as two subbands). In a second embodiment, reporting can be performed by having the same subband configuration for CQI, RI, and PMI, which allows for subband-based CQI, RI, and PMI reporting. That is, UE 604 can send reports indicating RI and PMI based on the same subband configuration used for CQI. In a third embodiment, reporting can be performed by having separate subband configurations for CQI, RI, and PMI.

[0126] UE 604 can perform reporting differently using periodic CSI (P-CSI), semi-persistent CSI (SP-CSI), or aperiodic CSI (A-CSI) to improve performance and / or reduce signaling overhead. For P-CSI reporting, UE 604 can periodically provide a single CQI / RI / PMI report to BS 602 (or two CQIs in the case of two codebooks). For SP-CSI and A-CSI reporting, UE 604 can utilize a subband-based approach, in which a single CQI / RI / PMI report is provided to BS 602, and subsequent reports are provided based on semi-persistent and / or aperiodic foundations.

[0127] In IBFD operation, UL resources (e.g., UL bands allocated as UL resources 502 and 512) may completely or partially overlap with DL resources (e.g., DL bands allocated as DL resources 504 and 514). UEs with IBFD capability can be configured to report... Figures 5A-5B Channel quality within the overlapping area shown. A UE with IBDF capability can perform channel measurements and reports based on CSI-RS received in the same frequency band as the band included in the active UL transmission, and CSI-RS received in frequency bands outside the active UL transmission band.

[0128] Active UL transmissions can be used to facilitate channel quality measurements for UE 604. Active UL transmissions performing DL channel measurements on it can be any UL transmission permitted in IBFD / subband FDD mode. For example, UL transmissions can include PUSCH, PUCCH, or Physical Random Access Channel (PRACH), provided UE 604 is configured to provide such transmissions. If UE 604 is not configured to perform any UL transmissions, UE 604 can send an indication to perform the reported measurements in the absence of UL transmissions; or, if the UE is configured to measure FD channels in these resources, UE 604 can send SRS. UE 604's configuration can be based on whether UE 604 has received UL permission from BS 602. When UE 604 does not send a UL signal, it can provide an indication to BS 602 so that BS 602 can take into account the lack of a UL signal.

[0129] In some respects, multiple CSF reports indicative of the interference cancellation (IC) capability of UE 604 can be sent to BS 602. UE 604 can send a first CSF report for the channel when IC is enabled and a second CSF report for the channel when IC is disabled, so that BS 602 can determine whether IC is desired. Multiple CSF reports indicative of active / inactive UL transmissions of UE 604 can also be sent to BS 602. Since active / inactive transmissions are independent of whether IC is enabled or disabled, such CSF reports provide BS 602 with further information about the characteristics of the channel.

[0130] In addition to the foregoing, UL signals transmitted during FD operations may affect RLM and / or RRM determination due to self-interference caused by the UL transmission. RLM can be performed to identify radio channels to be evaluated for link failures. UE 604 can receive RS, and UE 604 determines whether a radio channel includes a link failure based on RS (e.g., based on measurements or determinations of RSRP, RSRQ, SNR, SINR, RSSI, and / or other values ​​compared to thresholds). While UE 604 can indicate to BS 602 that a link failure has been identified during FD operations, this indication may distort the current situation because UL transmissions may cause excessive interference, preventing the necessary connection from being established over the link. Therefore, in some respects, UE 604 can be configured not to perform UL transmissions in symbols where the UE performs RLM measurements (e.g., no FD in the symbols where RLM measurements are performed). If UE 604 has UL transmissions configured in these symbols, UE 604 can discard the UL transmissions. In one example, BS 602 can provide an explicit indication that UE 604 will be in HD mode when measuring RLM resources; otherwise, BS 602 can operate assuming that the RLM measurement is performed in HD mode. Alternatively, a FD-enabled UE can perform both RLM and RRM measurements when configured with a sufficiently large guard band to account for residual self-interference of UE 604. A similar purpose can be achieved by manipulating the transmit power of UL resources.

[0131] When UE 604 is in Radio Resource Control (RRC) connected state, UE 604 can be similarly configured not to perform UL TX in the symbols where UE 604 performs RRM measurements (e.g., within the SS / PBCH Block Measurement Time Configuration (SMTC) window). Similarly, FD is not present in these symbols because UE 604 is not configured to transmit on UL during RRM measurements; or, if UE 604 is configured to perform UL TX in these symbols, UE 604 discards the UL TX. UE 604 can report to BS 602 whether the RRM measurement is based on FD UE or non-FD UE (e.g., HD UE) capability. The network can then refine the reported measurements for further evaluation. If the Cross-Link Interface (CLI) is available at the network, the network can be configured to identify the currently scheduled UE and determine whether the currently scheduled UE is in FD mode.

[0132] Figure 10This is a flowchart 1000 of a wireless communication method for a wireless device. The method can be performed by a device or apparatus (e.g., apparatus 1202) at a UE (e.g., UE 104, 350, 404a-c, 406a-c, 604, 702, which may include memory 360 and may be the entire UE 604 or certain components of UE 604, such as at least one processor (e.g., TX processor 368, RX processor 356, and / or controller / processor 359, any combination thereof) that may include units for performing the functions shown in the method of flowchart 1000. Depending on various aspects, one or more operations may be omitted, transposed, and / or performed simultaneously; for example, in some aspects, some operations shown in dashed lines may be omitted.

[0133] At position 1002, the UE sends a UL signal to the BS in the UL resource. For example, refer to Figure 6 UE 604 sends UL signal 607 to BS 602 in UL resource 606. The UL signal may include at least one of the following: SRS, DM-RS, a signal associated with control information on PUCCH (e.g., a signal that schedules the PUCCH within a time slot), a signal associated with data on PUSCH (e.g., a signal that schedules the PUSCH within a time slot), or another signal (e.g., another reference signal).

[0134] At position 1004, while transmitting the UL signal, the UE monitors the DL resource. This DL resource is adjacent to or at least partially overlaps with the UL resource. For example, the DL resource may at least partially overlap with the UL resource in the time domain, and may be adjacent to or at least partially overlap with the UL resource in the frequency domain. In some aspects, the UE can monitor the DL resource based on a configuration from the BS, which may configure the DL resource as a CSI-IM resource or may transmit at least one CSI-RS within the DL resource. For example, refer to... Figure 6 Simultaneously, at 606, while transmitting a UL signal 607 to BS 602 in UL resource 606, UE 604 monitors DL resource 608 from BS 602. In some aspects, UE 604 may receive at least one CSI-RS 609 from the monitored DL resource 608. (Refer to...) Figure 5A , 5B and Figure 8 DL resource 804 is adjacent to UL resource 802, DL resource 514 partially overlaps with UL resource 512, and UL resource 502 completely overlaps with DL resource 504.

[0135] At point 1006, the UE determines channel quality based on the UL signal in the UL resource. This channel quality can be associated with the DL resource. For example, the UE can measure RSRP, SNR, or other values ​​based on receiving at least one CSI-RS in the DL resource, or the UE can measure the total energy in the DL resource configured as a CSI-IM resource. Based on these measurements, the UE can determine (e.g., calculate, select, generate, etc.) at least one of PMI, RI, CQI, and / or other CSIs, for example, for each of multiple subbands or for broadband. For example, refer to Figure 6 UE 604 determines (610) the channel quality associated with DL resource 608 based on UL signal 607 in UL resource 606. This channel quality determination may be based on a comparison of two CSIs: a first CSI determined by transmitting UL signal 607 while monitoring DL resource 608; and a second CSI determined by monitoring DL resource 608 while avoiding transmitting any UL signal. The CSI may be based on at least one CSI-RS 609 received in DL resource 608 (e.g., CSI-RS resource and / or DL ​​resource 804) or on energy (e.g., signal strength, interference, etc.) measured on DL resource 608 configured as a CSI-IM resource.

[0136] In some aspects, such as for IBFD, the UE can determine at least one channel quality in a frequency band that includes both DL resources and UL resources (e.g., perform one or more measurements). That is, the UE can perform one or more measurements associated with channel quality based on at least one CSI-RS received in the same frequency band as the simultaneously transmitted UL signal. Furthermore, the UE can determine at least one channel quality in a frequency band adjacent to the frequency band that includes both DL resources and UL resources (e.g., perform one or more measurements). That is, the UE can perform one or more measurements associated with channel quality in a frequency band adjacent to the frequency band in which at least one CSI-RS is received and the UL signal is simultaneously transmitted (e.g., when the UE transmits the UL signal in the same frequency band, the UE can measure the channel quality in the adjacent frequency band).

[0137] In one configuration, at 1008, based on whether the UE's CSI reporting is configured as periodic (e.g., P-CSI), semi-persistent (e.g., SP-CSI), or aperiodic (e.g., A-CSI), the UE generates a CSF. Therefore, in some aspects, the UE can determine the reporting configuration associated with the CSI, and this reporting configuration can indicate that the CSI reporting will be one of periodic, semi-persistent, or aperiodic. For example, the UE can receive information from the BS for configuring the periodicity of CSI reporting (e.g., information configuring one of aperiodic, semi-persistent, or periodic CSI reporting). For example, when periodic CSI reporting is configured, the UE can generate a single CSF report for the BS (e.g., a single CSF may include a single RI, PMI, CQI, and / or other CSIs, which may be applicable to broadband bandwidth); however, when two codebooks are configured, the CSF may contain two CQIs. In another example, when the UE is configured to perform semi-persistent or aperiodic CSI reporting, the UE can generate multiple CSF reports for the BS. For example, each CSF report may include RI, PMI, CQI, and / or other CSIs for each of multiple subbands. (Reference) Figure 6 UE 604 determines whether the BS-based CSI report is configured to be periodic, semi-persistent, or aperiodic to generate (612)CSF 616.

[0138] In one configuration, at 1010, the UE determines the average CQI based on the previous CSI. Therefore, the CSF can include the CQI and send it to the BS to indicate whether the CQI is approximately equal to, greater than, or less than the average CQI. For example, refer to... Figure 6 UE 604 determines the average CQI (614) for example by measuring the channel quality of subcarriers extending over the entire DL band allocated as DL resource 804 and / or by calculating the average quality of the DL band allocated as DL resource 804. In some configurations, UE 604 may determine multiple CQIs, each of which is associated with a different subband among multiple subbands of the DL resource.

[0139] At point 1012, the UE transmits information indicating the Channel Quality Forecast (CSF) to the BS based on the determined channel quality. In some aspects, such as for IBDF, the UE may transmit CSF indication information based on at least one CSI-RS received in the same frequency band as the simultaneously transmitted UL signal, and potentially indicating a CSF based on measurements outside the same frequency band (e.g., when the UE transmits the UL signal in the same frequency band, the UE may measure the channel quality of adjacent frequency bands). The CSF indication information may indicate the frequency band associated with that CSF. For example, the UE may report a channel in the overlapping bandwidth between UL and DL resources in the CSF indication information.

[0140] For example, reference Figure 6 and Figure 8 UE 604 sends CSF 616 to BS 602, which may include at least one of CQI, RI, and / or PMI associated with DL resource 804. The CSF sent by UE 604 to BS 602 may also include multiple CQIs, multiple RIs, and / or multiple PMIs, each of which is associated with a different subband among multiple subbands of DL resource 804. Each of the multiple subbands associated with each of the CQIs, RIs, and / or PMIs may extend over the same number of RBs within DL resource 804, or may extend over an increasing number of RBs within DL resource 804 (as the subband moves away from DL resource 804).

[0141] In some aspects, when the CSF includes CQI, RI, and / or PMI, each of CQI, RI, and / or PMI can be reported to the BS based on different codebook subsets in different subbands of the DL resources used for CQI, RI, and / or PMI. In other aspects, when the CSF includes CQI, RI, and / or PMI, each of CQI, RI, and / or PMI can be reported to the BS based on the same subband configuration within the DL resources used for CQI, RI, and / or PMI (e.g., subband-based CQI, RI, and / or PMI reporting). In still other aspects, when the CSF includes CQI, RI, and / or PMI, each of CQI, RI, and / or PMI can be reported to the BS based on different subband configurations within the DL resources used for CQI, RI, and / or PMI.

[0142] In one configuration, the UE transmits a second UL signal to the BS in a second UL resource and simultaneously monitors a second DL resource configured by the BS. The second DL resource may be adjacent to or at least partially overlap with the second UL resource. The UE can then determine a second channel quality based on the monitored second DL resource. Based on the determined second channel quality, the UE can transmit a second CSF to the BS. For example, refer to... Figure 6 UE 604 can transmit a second UL signal similar to UL signal 607, but can transmit the second UL signal with a different configuration associated with at least one of different transmit power, different UL bandwidth, or different waveform.

[0143] In another configuration, the UE monitors other DL resources asynchronously with any UL transmissions from the UE. The UE can then determine another channel quality based on the monitored other DL resources, where these other DL resources are free from interference caused by the UL signals transmitted by the UE. The UE can then send the BS additional CSFs based on this second channel quality, along with an indication that this additional channel quality was determined without concurrent UL transmissions. For example, refer to... Figure 6 UE 604 can determine (610) the channel quality associated with DL resource 608 without the UL signal 607. (See reference...) Figure 7 UE 702 can avoid transmitting any UL signal 714 concurrent with DL resource 716. Then, UE 702 can transmit CSF 717 based on measurements of DL resource 716 (and / or at least one CSI-RS received therein).

[0144] In one configuration, at 1014, the UE performs at least one of an RLM measurement or an RRM measurement based on monitoring DL resources while transmitting UL signals. For example, the UE can select at least one resource overlapping between UL and DL resources in the time domain; however, in the aspect where the UE performs at least one of the RLM and / or RRM measurements, the UL resource may be adjacent to the DL resource (e.g., the UL resource may be separated from the DL resource by a guard band). The UE can then measure at least one value indicating energy, signal strength, and / or interference on the selected at least one resource. For example, the UE can measure the RSRP and / or RSRQ of at least one DL signal received from a BS on the selected at least one resource, and / or the UE can measure the RSRP and / or RSRQ of at least one other DL signal received from another BS (e.g., adjacent to that BS) on the selected at least one resource. For example, refer to... Figure 6UE 604 performs (620) RLM and / or RRM measurements 622 based on monitoring DL resources (e.g., based on receiving at least one CSI-RS 609 in DL resource set 608).

[0145] At point 1016, the UE sends a report to the BS indicating at least one result of the RLM and / or RRM measurements. In one configuration, the transmit power used to transmit the UL signal may be less than a threshold power level (e.g., to mitigate interference from the UL signal). For example, refer to... Figure 6 UE 604 sends RLM and / or RRM measurements 622 to BS 602.

[0146] In addition to the previously described configuration, at 1018, the UE sends information to the BS indicating that at least one of the RLM measurement and / or RRM measurement 622 associated with the report was performed in HD mode. For example, refer to Figure 6 UE 604 can send information 624 to BS 602 instructing UE 604 to operate in HD mode. The transmission of information 624 instructing UE 604 to operate in HD mode can be the same transmission as or different from the transmission of RLM and / or RRM measurement 622.

[0147] Figure 11 This is a flowchart 1100 of a wireless communication method for a wireless device. This method can be performed by a UE (e.g., UE 104, 350, 404a-c, 406a-c, 604, 702, which may include memory 360 and may be the entire UE 604 or a component of UE 604, such as at least one processor (e.g., TX processor 368, RX processor 356 and / or controller / processor 359, any combination thereof) or other means (e.g., means 1202) for performing the functions shown in the method of flowchart 1100. Depending on various aspects, one or more operations may be omitted, transposed, and / or performed simultaneously; for example, in some aspects, some operations shown in dashed lines may be omitted.

[0148] At 1102, the UE determines that the UL transmission to the first BS will be simultaneous with the DL resource on which at least one of the RLM or RRM measurements will be performed. For example, refer to Figure 7 UE 702 determines (708) that the UL signal 714 is scheduled to be transmitted simultaneously with the DL resource 716 to be monitored.

[0149] At 1104, when monitoring DL resources to receive DL signals, the UE avoids transmitting to the first BS in the UL. The UE can monitor DL ​​resources to receive DL signals from the first BS or from a second (e.g., adjacent) BS. For example, refer to... Figure 7 UE 702 avoids (710) transmitting in UL while monitoring DL resources by discarding UL signals 714 that are scheduled to be transmitted simultaneously with DL resources 716.

[0150] In one embodiment, the UE receives configuration from a second BS to perform at least one of RLM measurement or RRM measurement when in HD mode. For example, refer to Figure 7 UE 702 can receive configuration from the second BS 706, which causes UE 702 to discard the UL signal 714, which was scheduled to be transmitted while monitoring DL resource 716. The second BS 706 can be the same BS as the first BS 704, or it can be a different BS from the first BS 704.

[0151] At 1108, the UE performs at least one of an RLM measurement or an RRM measurement based on the received DL signal. The DL signal can be received from either a first BS or a second BS. In response to receiving the DL signal, the UE can measure at least one of RSRP, RSRQ, SNR, and / or other values, and can use at least one of RSRP, RSRQ, SNR, and / or other values ​​as an RLM measurement or an RRM measurement (e.g., when the DL signal is received from either the first BS or the second BS, respectively). For example, refer to... Figure 7 UE 702 uses a DL signal (e.g., a reference signal) from the first BS 704 or the second BS 706 to perform (718) RLM and / or RRM measurements 720.

[0152] At 1110, the UE transmits a report indicating at least one result of an RLM and / or RRM measurement. In some aspects, this report may indicate at least one of RSRP, RSRQ, SNR, and / or other values ​​used as RLM or RRM measurements (e.g., when a DL signal is received accordingly from a first BS or a second BS). For example, refer to... Figure 7 UE 702 can send information to BS 704 indicating the results of RLM and / or RRM measurements 720.

[0153] In one configuration, at 1112, the UE may send information indicating that at least one of the RLM and / or RRM measurements associated with the report was performed in HD mode (e.g., HD mode-based configuration 712). For example, refer to... Figure 7 UE 702 can send HD mode information 722 to BS 704. The transmission of HD mode information 722 can be the same as or different from the transmission of RLM and / or RRM measurement 720.

[0154] Therefore, transmitting a UL signal in UL resources simultaneously with monitoring DL resources (e.g., receiving CSI-RS and / or monitoring CSI-IM resources) allows the UE to measure and / or determine the quality of the channel between the UE and the BS. Based on the determined channel quality, the UE can transmit a CSF to the BS, enabling the BS to allocate DL resources in a manner that maintains the channel quality at or above a predefined threshold. Thus, the UE's channel measurement and reporting can improve communication efficiency by minimizing conditions that cause channel degradation below a predefined threshold.

[0155] Figure 12 Figure 1200 illustrates an example of a hardware implementation of device 1202. Device 1202 is a UE and includes a cellular baseband processor 1204 (also referred to as a modem) coupled to a cellular RF transceiver 1222, one or more Subscriber Identity Module (SIM) cards 1220, an application processor 1206 coupled to a Secure Digital Card (SD) card 1208 and a screen 1210, a Bluetooth module 1212, a Wireless Local Area Network (WLAN) module 1214, a Global Positioning System (GPS) module 1216, and a power supply 1218. The cellular baseband processor 1204 communicates with the UE 104 and / or BS 102 / 180 via the cellular RF transceiver 1222. The cellular baseband processor 1204 may include computer-readable media / memory. The computer-readable media / memory may be non-transitory. The cellular baseband processor 1204 is responsible for general processing, including the execution of software stored on the computer-readable media / memory. When the software is executed by the cellular baseband processor 1204, it causes the cellular baseband processor 1204 to perform the various functions described above. The computer-readable medium / memory can also be used to store data manipulated by the cellular baseband processor 1204 during software execution. The cellular baseband processor 1204 also includes a receiving component 1230, a communication manager 1232, and a transmitting component 1234. The communication manager 1232 includes one or more of the components shown. The components within the communication manager 1232 can be stored in a computer-readable medium / memory and / or configured as hardware within the cellular baseband processor 1204. The cellular baseband processor 1204 can be a component of the UE 350 and can include a memory 360 and / or at least one of a TX processor 368, an RX processor 356, and a controller / processor 359. In one configuration, the device 1202 can be a modem chip and only include the baseband processor 1204, while in another configuration, the device 1202 can be the entire UE (e.g., Figure 3 The UE 350, and includes the other modules discussed above for device 1202.

[0156] In some aspects, receiving component 1230 can receive information from BS 102 / 180 for configuring at least one UL resource set and at least one DL resource set for device 1202. The DL resource set and UL resource set may overlap at least partially in the time domain; for example, at least one symbol configured in the DL resource set may occur simultaneously with at least one symbol configured in the UL resource set. In the frequency domain, the DL resource set may be adjacent to the UL resource set (and may potentially be separated by a guard band), as in flexible FDD, or the DL resource set may overlap at least partially with the UL resource set, as in IBFD.

[0157] The DL resource set can be associated with CSI. In some aspects, the receiving component 1230 can receive information from BS 102 / 180 for configuring the DL resource set as a CSI-IM resource. In other aspects, the receiving component 1230 can receive information from BS 102 / 180 for configuring the DL resource set to carry at least one CSI-RS, for example, this information can schedule or allocate the DL resource set to carry at least one CSI-RS from BS 102 / 180.

[0158] In some respects, receiving component 1230 can receive UL authorization associated with a UL resource set from BS 102 / 180. This UL authorization can allocate or schedule UL signals on the UL resource set. For example, the UL authorization can allocate or schedule the UL resource set for control information to be carried on the PUCCH, or the UL authorization can allocate or schedule the UL resource set for data to be carried on the PUSCH.

[0159] In some further aspects, the receiving component 1230 can receive from BS 102 / 180 a transmission configuration associated with the transmission of UL signals in the UL resource set. This transmission configuration may indicate at least one of the transmit power, UL bandwidth, and / or waveform to be applied to the transmission of UL signals in the UL resource set. Potentially, the receiving component 1230 may receive multiple transmission configurations, wherein at least one of the transmit power, UL bandwidth, and / or waveform in one transmission configuration differs from at least one other transmit power, UL bandwidth, and / or waveform in other transmission configurations.

[0160] Transmitting component 1234 can be configured to transmit UL signals to BS 102 / 180 in UL resources, for example, as in combination with Figure 10As described in 1002. The UL signal may be at least one of SRS, DM-RS, a signal associated with control information on the (scheduled) PUCCH, a signal associated with data on the (scheduled) PUSCH, or another signal. In some aspects, the transmitting component 1234 may transmit the UL signal in the UL resource based on UL permission received from BS 102 / 180. In some other aspects, the transmitting component 1234 may transmit the UL signal in the UL resource without UL permission, for example when the UL signal is an SRS.

[0161] The transmitting component 1234 may obtain at least one of the transmit power, UL bandwidth, and / or waveform (indicated in at least one transmission configuration received from BS 102 / 180) as input from the receiving component 1230. The transmitting component 1234 may apply at least one of the transmit power, UL bandwidth, and / or waveform to transmit at least one UL signal in a UL resource.

[0162] Furthermore, the communication manager 1232 may include a monitoring component 1240 configured to monitor a set of DL resources configured using BS 102 / 180, for example, as combined with Figure 10 As described in 1004. While the transmitting component 1234 transmits UL signals in the UL resource set, the monitoring component 1240 can monitor the DL resource set.

[0163] The communication manager 1232 may also include a measurement component 1242, which is configured to perform one or more measurements associated with the DL resource set while the UL signal is being transmitted. For example, when the DL resource set is configured as a CSI-IM resource, the measurement component 1242 may measure the energy on the DL resource set while the UL signal is being transmitted. In another example, the receiving component 1230 is further configured to receive at least one CSI-RS on the DL resource set from BS 102 / 180 based on the monitoring of the DL resource set by the monitoring component 1240, and the measurement component 1242 is configured to measure or otherwise determine at least one value (e.g., RSRQ, RSSI, SINR, SNR, and / or another value) in response to receiving at least one CSI-RS on the monitored DL resource set.

[0164] Communication manager 1232 may include channel quality component 1244, which is configured to determine the channel quality associated with the DL resource set based on UL signals transmitted in the UL resource set, for example, as in combination with Figure 10As described in 1006. In some aspects, the channel quality component 1244 may obtain input from the measurement component 1242 indicating one or more measurement results (e.g., measured energy, RSRP, SNR, etc.), and the channel quality component 1244 may determine the CSI based on the one or more measurement results.

[0165] For example, the channel quality component 1244 can determine at least one of CQI, PMI, and / or RI based on the one or more measurement results. In some aspects, at least one of CQI, RI, or PMI can be associated with broadband bandwidth. In some other aspects, the DL resource set is divided into multiple subbands, and the channel quality component 1244 can determine at least one of multiple CQIs, multiple RIs, and / or multiple PMIs, each of the multiple CQIs associated with a corresponding one of the multiple subbands, each of the multiple RIs associated with a corresponding one of the multiple subbands, and each of the multiple PMIs associated with a corresponding one of the multiple subbands. Each of the multiple subbands can extend over the same number of RBs in the DL resource set, or each of the multiple subbands can extend over an increasing number of RBs in the DL resource set proportional to the distance from the UL resource set.

[0166] In some aspects, the communications manager 1232 may include a reporting configuration component 1246 configured to determine a reporting configuration associated with the CSI, indicating that the CSI's reporting will be periodic, semi-persistent, or aperiodic. In some aspects, this reporting configuration may be received from the BS 102 / 180 via the receiving component 1230. For example, the reporting configuration may be received in the DCI or via RRC signaling.

[0167] In some aspects, the communication manager 1232 may include an ACLR component 1248 configured to determine ACLR based on the transmission of UL signals in the UL resource set. For example, when at least one UL signal is transmitted in the UL resource set while monitoring the DL resource set, the ACLR component 1248 may determine one or more values ​​of ACLR (e.g., based on measurements performed in one or more subbands and / or channels adjacent to the DL resource set).

[0168] Potentially, the ACLR component 1248 can determine a plurality of ACLR values, each of which corresponds to a different transmission configuration for transmitting UL signals in a UL resource set. Each ACLR value may correspond to at least one of transmit power, UL bandwidth, and / or waveform. Thus, each ACLR value may implicitly indicate which transmission configuration to apply to mitigate or minimize the amount of UL signal that introduces interference to adjacent channels (e.g., consecutive subcarriers and / or subbands).

[0169] The transmitting component 1234 can send information indicating one or more ACLR values ​​to the BS 102 / 180. However, for example, when the device 1202 is transmitting one or more UL signals, the BS 102 / 180 can measure one or more ACLR values, so the device 1202 can avoid sending ACLR values ​​to the BS 102 / 180.

[0170] The communication manager 1232 may also include a feedback generation component 1250, which receives input based on the determined channel quality from the channel quality component 1244 and / or based on the CSI report configuration from the report configuration component 1246. The feedback generation component 1250 may be configured to generate information indicating a CSF. For example, a CSF report may be associated with a DL resource set and / or may be based on the transmission of UL signals in a UL resource set that is adjacent to or at least partially overlaps with the DL resource set (e.g., in the frequency domain).

[0171] Feedback generation component 1250 can be configured to generate CSF to include and / or be based on CSI (e.g., as determined by channel quality component 1244). Therefore, feedback generation component 1250 can be configured to generate CSF reports to include at least one of CQI, PMI, RI, and / or other CSIs (e.g., as obtained from channel quality component 1244).

[0172] For example, the feedback generation component 1250 can be configured to generate a CSF indicating a single RI, a single PMI, and / or a single CQI when the report configuration component 1246 provides an indication that the CSI report is configured to be periodic; however, when communication with the BS 102 / 180 uses two codebooks, the CSF may include at least two CQIs. In such an example, the RI, PMI, and / or CQI may be associated with broadband bandwidth. In another example, when the report configuration component 1246 provides an input indicating that the CSI report is configured to be semi-persistent or non-periodic, the feedback generation component 1250 can be configured to generate at least one corresponding RI, PMI, and / or CQI for each of a plurality of subbands (e.g., a DL resource set may be divided into subbands therein).

[0173] In other respects, the feedback generation component 1250 can be configured to generate one or more CSF reports to indicate a first number N of RIs, a second number L of PMIs, and a third number M of CQIs for different subbands. For example, the feedback generation component 1250 can generate one or more CSF reports to indicate N RIs determined for N subbands, L PMIs determined for L subbands, and / or M CQIs determined for M subbands. Potentially, at least two of L, M, and / or N can be equal.

[0174] According to one example, BS 102 / 180 can be explicitly configured with different codebook subset restrictions corresponding to different subbands. For example, at least one codebook subset restriction can be received from BS 102 / 180 via RRC signaling through receiving component 1230, as a codebook subset restriction information element or its field. The codebook subset restriction can be configured with N RIs for N subbands, L PMIs for L subbands, and / or M CQIs for M subbands.

[0175] According to another example, each of the plurality of subbands can be associated with a separate configuration for configuring each of the N RIs of the N subbands, the L PMIs of the L subbands, and / or the M CQIs of the M subbands, wherein each of L, M, and N is equal based on the subband-based configuration. According to another example, each of the N RIs of the N subbands, the L PMIs of the L subbands, and the M CQIs of the M subbands can be configured separately.

[0176] When BS 102 / 180 configures its communication with device 1202 to include IBDF operation, feedback generation component 1250 can be configured to generate CSF to report information based on the channel quality in the determined full channel (which includes the overlapping bandwidth between UL and DL resources). For example, feedback generation component 1250 may include information indicating a set of measurement results, each based on at least one CSI-RS received in a DL resource set overlapping with a UL resource set in which at least one UL signal is transmitted. Furthermore, feedback generation component 1250 may include information indicating a set of measurement results, each based on at least one other frequency band (e.g., sub-band and / or channel) adjacent to the DL resource set overlapping the UL resource set (e.g., one or more measurements may be performed in adjacent frequency bands when at least one UL signal is transmitted).

[0177] In some additional aspects, the feedback generation component 1250 can be configured to generate a first CSF report based on the channel quality determined in association with the DL resource set when a UL signal is transmitted in the UL resource set and the device 1202 avoids performing interference cancellation (e.g., self-interference cancellation) on the UL signal in the DL resource set. The feedback generation component 1250 can also be configured to generate a second CSF report based on the channel quality determined in association with the DL resource set when a UL signal is transmitted in the UL resource set and the device 1202 performs interference cancellation (e.g., self-interference cancellation) on the UL signal in the DL resource set.

[0178] In other respects, the feedback generation component 1250 can be configured to generate a CSF report based on channel quality determined in the DL resource set in the absence of UL signal transmission. For example, such a CSF report could be based on channel quality reflecting interference caused by neighboring BSs and / or UEs, and not represent self-interference.

[0179] In other respects, the feedback generation component 1250 can be configured to generate at least one CSF report based on channel quality determined when the transmitting component 1234 transmits at least one UL signal in a UL resource set according to one transmission configuration (e.g., one transmit power, UL bandwidth, and / or waveform). The feedback generation component 1250 can also be configured to generate at least one CSF report based on another channel quality determined when the transmitting component 1234 transmits at least one other UL signal in another UL resource set according to another transmission configuration (e.g., another transmit power, UL bandwidth, and / or waveform). Potentially, one or more ACLR values ​​can be associated with each CSF report based on at least one UL signal transmitted according to a corresponding transmission configuration. Therefore, the ACLR component 1248 and / or the feedback generation component 1250 can be configured to generate information indicating which transmission configuration causes interference (and the degree of interference) in adjacent frequency bands.

[0180] The transmitting component 1234 can obtain input from the feedback generation component 1250 and can be further configured to transmit information indicating the CSF to the base station 102 / 180, for example, as combined with Figure 10 As described in 1012. Transmitting component 1234 can be configured to transmit information indicating CSF on an uplink channel such as PUCCH or PUSCH. In some aspects, transmitting component 1234 can be configured to transmit information indicating CSF based on at least one reporting configuration (e.g., as obtained via input from reporting configuration component 1246).

[0181] For example, the transmitting component 1234 can be configured to periodically, semi-persistently, or non-periodically (e.g., trigger-based) transmit information indicating a CSF, depending on a report configuration. In some cases, the receiving component 1230 can be configured to receive, for example, information from the BS 102 / 180 to trigger non-periodic transmission of information indicating a CSF, via DCI, RRC signaling, and / or MAC control element (CE). Therefore, the transmitting component 1234 can be configured to non-periodically transmit information indicating a CSF to the BS 102 / 180 in response to receiving information triggering non-periodic transmission via the receiving component 1230.

[0182] In some other cases, receiving component 1230 may be configured to receive, for example via DCI, RRC signaling, and / or MAC CE, information from BS 102 / 180 for triggering (or initiating) a semi-persistent transmission of information indicating CSF. Therefore, transmitting component 1234 may be configured to semi-persistently (e.g., periodically until released) transmit information indicating CSF to BS 102 / 180 in response to receiving information from receiving component 1230 for triggering (or initiating) a semi-persistent transmission. Subsequently, receiving component 1230 may be configured to receive, for example via DCI, RRC signaling, and / or MAC CE, information from BS 102 / 180 for releasing (or terminating) the semi-persistent transmission of information indicating CSF. Therefore, transmitting component 1234 may be configured to stop transmitting information indicating CSF to BS 102 / 180 in response to receiving information from receiving component 1230 for releasing (or terminating) the semi-persistent transmission.

[0183] The communication manager 1232 may also include an RLM / RRM component 1252 configured to perform at least one of RLM and / or RRM measurements based on monitoring DL resources, for example, as in combination with Figure 10 As described in 1014. For example, the RLM / RRM component 1252 can be configured to perform at least one RLM and / or RRM measurement based on at least one DL signal (e.g., CSI-RS or other DL signal) received in the DL resource set configured in BS 102 / 180. In some configurations, the RLM / RRM component 1252 can be configured to perform at least one RLM and / or RRM measurement when the device 1202 is configured in HD operating mode.

[0184] Illustratively, the RLM / RRM component 1252 can be configured to measure RSRP, RSRQ, and / or SNR in response to receiving at least one DL signal from BS 102 / 180, and / or the RLM / RRM component 1252 can be configured to measure RSRP, RSRQ, and / or SNR in response to receiving at least one other DL signal from another BS adjacent to BS 102 / 180. The RLM / RRM component 1252 can be configured to perform at least one RLM and / or RRM measurement in the absence of any UL signal that may interfere with the at least one DL signal and / or the at least one other DL signal.

[0185] The sending component 1234 can be configured to send at least one report to BS 102 / 180 indicating the results of performing at least one RLM and / or RRM measurement, for example, as in combination with Figure 10As described in 1016. In some aspects, the transmitting component 1234 can also be configured to: transmit to BS 102 / 180 information indicating that at least one RLM and / or RRM measurement is performed when the device 1202 is configured in HD operating mode, for example, as in combination with Figure 10 As described in 1018.

[0186] In some further aspects, the RLM / RRM component 1252 can be configured to determine that a UL signal to be sent to BS 102 / 180 will (e.g., be scheduled) be simultaneous with a DL signal for which at least one RLM and / or RRM measurement will be performed, for example, as combined Figure 11 As described in 1102. For example, RLM / RRM component 1252 can identify a set of UL resources in the time domain, wherein UL signals are scheduled to be transmitted in the set of UL resources, and further, can identify a set of DL resources in the time domain, wherein DL signals are scheduled to be transmitted in the set of DL resources.

[0187] RLM / RRM component 1252 can be configured to compare a UL resource set with a DL resource set, and based on this, determine whether the UL and DL resource sets overlap in time. If it is determined that the UL and DL resource sets overlap in time, RLM / RRM component 1252 can determine that a UL signal to be sent to BS 102 / 180 will (e.g., be scheduled) be simultaneous with a DL signal for which at least one RLM and / or RRM measurement will be performed.

[0188] When RLM / RRM group 1252 determines that a UL signal to be sent to BS 102 / 180 will (e.g., be scheduled) be simultaneous with a DL signal for which at least one RLM and / or RRM measurement will be performed, RLM / RRM group 1252 can configure transmitting component 1234. Based on this configuration, when a DL signal is received in the DL, transmitting component 1234 can avoid transmission to BS 102 / 180 in the UL, for example, as in combination with... Figure 11 As described in 1104.

[0189] In some aspects, receiving component 1230 can be configured to receive a configuration from a second BS (e.g., a BS adjacent to BS 102 / 180) indicating that RLM and / or RRM measurements will be performed when device 1202 is configured in HD operating mode, for example, as combined with Figure 11 As described in 1106.

[0190] RLM / RRM component 1252 can be configured to perform at least one of RLM and / or RRM measurements based on the received DL signal, for example, as in combination Figure 11As described in 1108. DL signals can be received from BS 102 / 180 or from a BS adjacent to BS 102 / 180. For example, RLM / RRM component 1252 can measure at least one of RSRP, RSRQ, SNR, and / or other values ​​in response to receiving at least one DL signal from BS 102 / 180 or from an adjacent BS, and the results of RLM and / or RRM measurements can be based on at least one of RSRP, RSRQ, SNR, and / or other values.

[0191] The sending component 1234 can be configured to send a report indicating at least one result of RLM and / or RRM measurements, for example, as in combination with Figure 11 As described in 1110. For example, sending component 1234 can send such a report to BS 102 / 180 (or potentially, to an adjacent BS). Sending component 1234 can also be configured to send information indicating that at least one of the RLM and / or RRM measurements associated with the report was performed in HD mode, for example, as in combination with Figure 11 As described in 1112.

[0192] The device may include means for performing Figure 6 , 7 10 and / or Figure 11 The other components of each box in the aforementioned call flowchart and / or the algorithm within the flowchart. Therefore, Figure 6 , 7 10 and / or Figure 11 Each box in the aforementioned call flowchart and / or flowchart can be executed by a component, and the apparatus may include one or more of these components. These components may be one or more hardware parts specifically configured to perform the stated processing / algorithm, implemented by a processor configured to perform the stated processing / algorithm, stored in a computer-readable medium for implementation by a processor, or some combination thereof.

[0197] In some respects, UL signals include at least one of the following: SRS, DM-RS, signals associated with control information on the PUCCH, and / or signals associated with data on the PUSCH.

[0198] In some aspects, the apparatus 1202 (and specifically, the cellular baseband processor 1204) may include: a unit for transmitting another UL signal in another UL resource set in a different configuration than a first configuration in which it transmits the UL signal using the UL resource set, and the other configuration includes at least one of the transmit power, UL bandwidth, or waveform different from those included in the first configuration. In these aspects, the apparatus 1202 (and specifically, the cellular baseband processor 1204) may also include: a unit for monitoring another DL resource set configured using the BS, the other DL resource set being adjacent to or at least partially overlapping the other UL resource set. In addition to these aspects, the apparatus 1202 (and specifically, the cellular baseband processor 1204) may also include: a unit for determining another channel quality associated with the other DL resource set based on the other UL signal transmitted in the other UL resource set. Furthermore, in these aspects, the apparatus 1202 (and specifically, the cellular baseband processor 1204) may also include: a unit for transmitting additional information indicating other CSFs to the BS based on another determined channel quality.

[0199] In some aspects, the information indicating the CSF includes at least one of CQI, RI, and / or PMI. In some aspects, the DL resource set includes multiple subbands, and wherein the information indicating the CSF includes at least one of multiple CQIs, multiple RIs, or multiple PMIs, each of the multiple CQIs associated with a corresponding one of the multiple subbands, each of the multiple RIs associated with a corresponding one of the multiple subbands, and each of the multiple PMIs associated with a corresponding one of the multiple subbands. In some aspects, each of the multiple subbands extends on the same number of RBs in the DL resource set. In some aspects, each of the multiple subbands extends on an increasing number of RBs in the DL resource set proportional to the distance from the UL resource set. In some aspects, at least one of the CQI, RI, or PMI is associated with broadband bandwidth.

[0200] In some respects, the device 1202 (and more specifically, the cellular baseband processor 1204) may also include a unit for sending information indicating at least one ACLR to the BS.

[0201] In some aspects, the device 1202 (and more specifically, the cellular baseband processor 1204) may also include: a unit for receiving UL authorization from the BS, and the ability to transmit UL signals in the UL resource set based on the UL authorization.

[0202] In some aspects, the apparatus 1202 (and more specifically, the cellular baseband processor 1204) may further include: a unit for determining a reporting configuration associated with the CSI, the reporting configuration indicating that the CSI reporting is one of periodic, semi-persistent, or non-periodic; and a unit for determining the CSF based on the reporting configuration, determining the CSF differently for periodic CSI reports, semi-persistent CSI reports, and non-periodic CSI reports.

In some other aspects, the device 1202 (and specifically, the cellular baseband processor 1204) may also include a unit for transmitting information indicating that at least one of the RLM and / or RRM measurements associated with the report was performed in HD mode.

[0207] The aforementioned units may be one or more of the aforementioned components of device 1202 configured to perform the functions described in the aforementioned units. As described above, device 1202 may include TX processor 368, RX processor 356, and controller / processor 359. Therefore, in one configuration, the aforementioned units may be TX processor 368, RX processor 356, and controller / processor 359 configured to perform the functions described in the aforementioned units.

[0208] Figure 13 This is a flowchart 1300 of a wireless communication method. The method can be performed by a BS (e.g., BS 102 / 180, 310, 402a-c, 408a-c, 602, 704, 706) or a device (e.g., device 1402). Depending on various aspects, one or more operations may be omitted, transposed, and / or performed simultaneously; for example, in some aspects, some operations shown by dashed lines may be omitted.

[0209] At position 1302, the BS can send a UL permission to the UE, which allocates a UL resource set to the UE for transmitting UL signals. For example, refer to... Figure 6 BS 602 can send a UL permission to UE 604 to allocate UL resources 606 to UE 604 for sending UL signals 607.

[0210] In some respects, the BS may additionally send the UE a configuration for the transmission of UL signals, and the configuration includes at least one of transmit power, UL bandwidth, or waveform.

[0211] At point 1304, the BS can configure the UE to report CSI, where the CSI is periodic, semi-persistent, or aperiodic. For example, first, the BS can determine the periodicity of the CSI reporting by the UE. Potentially, the BS can determine that the UE is not reporting CSI periodically, but rather that the UE's CSI reporting is aperiodic, for example, causing the BS to trigger the UE's CSI reporting. Then, the BS can send information to the UE instructing the UE to report CSI periodically, semi-persistently, or aperiodically. The BS can send such information via DCI and / or RRC signaling. For example, refer to... Figure 6 BS 602 can configure UE 604 to report CSI as one of periodic, semi-persistent, or aperiodic.

[0212] At 1306, the BS can configure a DL resource set associated with the CSI for the UE. This DL resource set may be adjacent to or at least partially overlap with the UL resource set. Specifically, the DL resource set may at least partially overlap with the UL resource set in the time domain; however, in the frequency domain, for example for IBDF, the DL resource set may be adjacent to the UL resource set (e.g., separated by a guard band), or for example for flexible (or sub-band) FDD DL, the DL resource set may at least partially overlap with the UL resource set.

[0213] In some respects, the BS can configure DL resources as CSI-IM resources, or the BS can configure DL resources to carry at least one CSI-RS. To configure a set of DL resources to the UE, firstly, the BS can schedule or allocate a set of resources for CSI-IM or CSI-RS transmission within a frequency band at least partially dedicated to DL communication; secondly, the BS can send information to the UE indicating the scheduling or allocation of this set of resources. For example, refer to... Figure 6 BS 602 can configure a DL resource set 608 associated with CSI to UE 604. This DL resource set 608 may be adjacent to or at least partially overlap with the UL resource set 606. For example, BS 602 can configure DL resource 608 as a CSI-IM resource, or BS can configure DL resource 608 to carry at least one CSI-RS 609.

[0214] At point 1308, the BS can send at least one CSI-RS from the DL resource set to the UE. For example, the BS can schedule at least one CSI-RS within the DL resource. In some other aspects, when the BS configures the DL resource as a CSI-IM resource, the BS can avoid sending at least one CSI-RS, for example, because the CSI-IM resource can be used to measure energy and / or signal strength from neighboring devices (e.g., neighboring BSs, UEs operating in neighboring cells, and / or other BSs and UEs). For example, refer to... Figure 6 BS602 can configure DL resource set 608 associated with CSI for UE 604.

[0215] In some aspects, the UE may transmit at least one UL signal in a UL resource, wherein the UL resource may be adjacent to or at least partially overlap with the DL resource. For example, the UL signal may be at least one of the following: SRS, control information in PUCCH, data in PUSCH, DM-RS, and / or another UL signal that may or may not be a reference signal. Accordingly, the BS may receive at least one UL signal transmitted by the UE in the UL resource.

[0216] The UE may transmit at least one UL signal based on UL permission sent to the UE; however, the UE may transmit some UL signals (e.g., SRS) without UL permission. Alternatively or additionally, the UE may transmit at least one UL signal based on a configuration including at least one of transmit power, UL bandwidth, or waveform.

[0217] In some respects, the UE can transmit different UL signals on different UL resource sets based on different configurations (e.g., different transmit power, different UL bandwidth, and / or different waveforms). Then, for example, when the UE transmits UL signals in the corresponding UL resource set corresponding to each DL resource set, or when the UE avoids transmitting UL signals in the corresponding UL resource set corresponding to one of these DL resource sets, the UE can determine the corresponding channel quality for each DL resource set configured for that UE.

[0218] At 1310, the BS can receive information from the UE indicating a CSF based on a DL resource set. This CSF may include at least one of CQI, RI, PMI, and / or other CSIs. For example, refer to... Figure 6 BS 602 can receive information from UE 604 indicating CSF 616, which may be based on DL resource set 608 configured by BS 602 to be monitored by UE 604.

[0219] Information indicating a CSF may include one or more CSF reports. For example, information indicating a CSF may include: a first CSF report based on a UL signal 607 in a UL resource 606 that is adjacent to or partially overlaps with DL resource 608; a second CSF report based on another UL signal that has a different configuration (e.g., different transmit power, different UL bandwidth, and / or different waveform) compared to UL signal 607; and / or a third CSF report (based on the absence of a UL signal in a UL resource that is adjacent to or at least partially overlaps with the DL resource that is configured to be monitored by the UE).

[0220] Furthermore, the information indicating the CSF may include information instructing the UE on the conditions under which it determines the CSF. For example, the information indicating the CSF may indicate the configuration used by the UE to transmit UL signals. In another example, the information indicating the CSF may indicate whether the UE applies interference cancellation (e.g., self-interference cancellation) to UL signals transmitted in UL resources adjacent to or at least partially overlapping with DL resources. In yet another example, the information indicating the CSF may indicate whether the UE transmits UL signals in UL resources (e.g., this information may indicate that the CSF is based on measurements of the DL resources performed without any UL signals from the UE).

[0221] In some aspects, the information indicating CSF can be based on the periodicity of CSI reporting configured to the UE. For example, the information indicating CSF can vary depending on whether the UE is configured to report CSI periodically, semi-persistently, or aperiodically. In some further aspects, the information indicating CSF can include at least: a first CSF report based on the UE's interference cancellation (e.g., the UE may perform self-interference cancellation, for example, for UL signals), and a second CSF report based on the UE not performing interference cancellation (e.g., the UE may avoid performing self-interference cancellation, for example, for UL signals).

[0222] In some aspects, the DL resource set can be divided into multiple subbands (e.g., multiple subbands of the DL bandwidth), and the CSF can include at least one of the following for each of the multiple subbands: CQI, RI, PMI, and / or other CSIs. For example, each of the multiple subbands can extend over an increasing number of RBs in the DL resource set in proportion to the distance from the UL resource set. In another example, each of the multiple subbands can extend over the same number of RBs in the DL resource set. In some other aspects, the CSF can include at least one of the following for the broadband bandwidth (e.g., the DL bandwidth or a configured portion thereof): CQI, RI, PMI, and / or other CSIs.

[0223] In some respects, the BS may further determine the following information: information indicating the ACLR associated with the UE transmitting at least one UL signal in UL resources. The information indicating the ACLR may include an ACLR profile and may indicate the ratio of transmit power (e.g., for UL signal transmission) to power measured in adjacent channels (e.g., energy “leaking” from the UL signal transmitted at that transmit power into adjacent subbands that may not be allocated to that UL signal).

[0224] ACLR may include and / or may be based on the amount of at least one UL signal “leaking” on a resource adjacent to the UL resource in which the UL signal is transmitted (e.g., the energy of at least one detectable UL signal). Therefore, ACLR may include and / or may be based on the energy from the UL signal, which may be detectable on at least one adjacent (e.g., consecutive) subband in the lower portion of the spectrum (e.g., at least one lower subband) and / or the higher portion of the spectrum (e.g., at least one higher subband).

[0225] In some respects, such as when the UE transmits a UL signal in UL resources, the BS can measure ACLR. However, in other respects, the BS can receive information from the UE indicating ACLR.

[0226] The BS can receive information indicating ACLR in the UE capability message or auxiliary information. For example, the UE can measure ACLR when transmitting each of the at least one UL signal, where ACLR is affected differently depending on the corresponding configuration used to transmit each of the at least one UL signal. That is, ACLR can be affected by the transmit power, UL bandwidth, and / or waveform used to transmit the UL signal in the UL resources.

[0227] At 1312, the BS can configure communication with the UE based on information indicating the CSF. For example, the BS can configure communication based on the information indicating the CSF by determining (e.g., selecting, identifying, calculating, etc.) one or more parameters associated with at least one of IBFD and / or flexible (or subband) FDD; although these parameters are not necessarily unique to IBFD and / or flexible FDD. Subsequently, the BS can apply at least one of said one or more parameters, for example, causing BS-to-UE transmission and / or reception based on at least one parameter, and / or the BS can send information to the UE indicating at least one of said one or more parameters, for example, causing UE-to-BS transmission and / or reception based on said at least one parameter. For example, refer to... Figure 6 BS 602 can configure communication with UE 604 based on the information received from UE 604 indicating CSF 616.

[0228] In some aspects, the BS can further configure communication with the UE based on at least one ACLR. The BS can measure the value of the ACLR, and / or the BS can receive information from the UE indicating the ACLR. In some aspects, the BS can configure communication with the UE based on multiple ACLRs, wherein each ACLR corresponds to a corresponding CSF and the channel quality on which the corresponding CSF is based. Illustratively, one ACLR may correspond to a CSF determined based on channel quality, which is determined in conjunction with the transmission of UL signals while monitoring DL resources; another ACLR may correspond to a CSF determined based on another channel quality, which is determined in conjunction with the transmission of another UL signal using different configurations (e.g., different transmit power, different UL bandwidth, different waveforms, etc.); and a third ACLR may correspond to a CSF determined based on yet another channel quality, determined by preventing the UE from simultaneously transmitting any UL signals while monitoring DL resources.

[0229] Since the BS determines one or more parameters based on the CSF associated with the DL resources on the channel on which the BS and UE are configured to communicate, the one or more parameters can be applied to communication on the channel on which the BS and UE are configured to communicate. For example, the one or more parameters can be applied to FD operations (e.g., IBFD and / or flexible FDD) performed at least by the BS (e.g., the UE can be configured for FD or HD operations).

[0230] In some respects, the BS can recognize values ​​in the CSF, such as CQI, and then the BS can access tables (e.g., lookup tables) or other data structures that can be keyed using values ​​determined in the CSF. Next, the BS can select the parameter corresponding to that value based on the table or other data structure.

[0231] For example, the BS can identify a CQI index equal to 2 from the CSF. The BS can then access a table or other data structure keyed by the CQI index, and this table or data structure includes a set of columns with parameters (e.g., modulation and coding scheme (MCS)) corresponding to each CQI index. The BS can identify at least one entry in this table or other data structure corresponding to a CQI index of 2, for example, this at least one entry may include a first parameter (e.g., QPSK) from the modulation scheme column and a second parameter (e.g., 120×1024) from the code rate column. Therefore, the BS can configure communication with the UE to have a QPSK modulation scheme and a code rate of 120×1024 based on the CSF indicating a CQI index of 2.

[0232] In some other aspects, the BS can configure precoding, such as the precoding matrix and / or precoding format, based on information indicating the CSF. In further aspects, the BS can determine or select one or more of the following based on the CSF: transmission mode, TB size, number of spatial layers, and / or number of TX and / or RX antennas. In other aspects, the BS can determine whether communication is codebook-based or non-codebook-based based on the CSF, and if codebook-based, configure the codebook. In still further aspects, the BS can determine MIMO parameters, TX and / or RX beams (e.g., Transmission Configuration Indicator (TCI) status), and / or other parameters based on the CSF.

[0233] Figure 14 Figure 1400 illustrates an example of a hardware implementation of device 1402. Device 1402 is a BS and includes a baseband unit 1404.

Baseband unit 1404 is responsible for general processing, including the execution of software stored on computer-readable medium / memory. When the software is executed by baseband unit 1404, it causes baseband unit 1404 to perform the various functions described above. Computer-readable medium / memory can also be used to store data manipulated by baseband unit 1404 during software execution. Baseband unit 1404 also includes a receiving component 1430, a communication manager 1432, and a transmitting component 1434. Communication manager 1432 includes one or more of the components shown.

[0234] In some aspects, the transmitting component 1434 can be configured to transmit at least one UL permission to the UE 104, which allocates at least one UL resource set to the UE 104 for transmitting at least one UL signal, for example, as in combination with Figure 13 As described in 1302. In some other respects, these UL resources may not include any UL signals; for example, transmitting component 1434 may avoid sending UL permission to UE 104.

[0235] Furthermore, the transmitting component 1434 can be configured to transmit a configuration for the transmission of UL signals to the UE 104, wherein the configuration indicates at least one of the transmit power, UL bandwidth, and / or waveform.

[0236] In some aspects, receiving component 1430 may be configured to receive at least one UL signal from UE 104 in a UL resource set. For example, at least one UL signal may be received based on the at least one UL permission, and / or at least one UL signal may be received based on a configuration indicating transmit power, UL bandwidth, and / or waveform. Depending on various aspects, the at least one UL signal may be at least one of the following: SRS, control information in PUCCH, data in PUSCH, DM-RS, and / or another UL signal (which may or may not be a reference signal).

[0238] The communication manager 1432 may also include a resource configuration component 1440, which configures a DL resource set associated with the CSI for the UE 104, and the DL resource set may be adjacent to or at least partially overlap with the UL resource set, for example, as in combination. Figure 13 As described in 1306. The UL resource set may at least partially overlap with the DL resource set in the time domain, and the DL resource set may be adjacent to or at least partially overlap with the UL resource set in the frequency domain.

[0239] In some aspects, resource configuration component 1440 can configure the DL resource set as a CSI-IM resource for UE 104. In other aspects, resource configuration component 1440 can configure the DL resource set to carry at least one CSI-RS, for example, it can provide UE 104 with scheduling information indicating the allocation of at least one CSI-RS on the DL resource set. Transmission component 1434 can be further configured to transmit at least one CSI-RS to UE 104 in the DL resource set, for example, as in combination with Figure 13 As described in 1308.

[0240] The receiving component 1430 may be further configured to receive information from the UE 104 indicating a CSF based on a DL resource set, for example, as combined with Figure 13 As described in 1310. In some respects, the information indicating CSF includes at least: a first CSF report based on interference cancellation of UE 104, and a second CSF report based on the fact that interference cancellation was not performed on UE 104.

[0241] In some other respects, the information indicating CSF can be based on the configuration of UE 104 to report one of the periodic, semi-persistent, or aperiodic CSI.

[0242] The communication manager 1432 may also include a communication configuration component 1444, which configures communication with the UE 104 based on information indicating the CSF, for example, as in conjunction with Figure 13 As described in 1312. In some aspects, the information indicating the CSF may be further based on at least one CSI-RS or may be based on a DL resource set as a configuration of the CSI-IM resource (e.g., the transmitting component 1434 may avoid transmitting any DL signals in the CSI-IM resource).

[0243] In some aspects, the information indicating the CSF may include at least one of CQI, PMI, and / or RI based on the DL resource set. In some aspects, at least one of the CQI, RI, or PMI may be associated with broadband bandwidth. In some other aspects, the DL resource set is divided into multiple subbands, and the channel quality component 1244 may determine at least one of multiple CQIs, multiple RIs, and / or multiple PMIs, each of the multiple CQIs associated with a corresponding one of the multiple subbands, each of the multiple RIs associated with a corresponding one of the multiple subbands, and each of the multiple PMIs associated with a corresponding one of the multiple subbands. Each of the multiple subbands may extend over the same number of RBs in the DL resource set, or each of the multiple subbands may extend over an increasing number of RBs in the DL resource set proportional to the distance from the UL resource set.

[0244] In some aspects, the communication configuration component 1444 may further configure communication with the UE 104 based on at least one ACLR. For example, each ACLR may correspond to the corresponding transmission of UL signals in the UL resource set using a corresponding transmission configuration (e.g., configuring at least one of transmit power, UL bandwidth, and / or waveform for transmitting UL signals in UL resources).

[0245] In some aspects, the communication configuration component 1444 may determine (e.g., measure) at least one ACLR, for example, based on the transmission of at least one UL signal in at least one UL resource set by the UE 104. In some other aspects, the receiving component 1430 may receive at least one ACLR from the UE 104, for example, in association with the transmission of at least one UL signal in at least one UL resource set.
