Channel state information reporting

Abstract

Various aspects of the present disclosure relate to channel state information (CSI) reporting. A device, e.g., a user equipment (UE), receives first signaling configuring a channel state information-reference signal (CSI-RS). The first signaling indicates a set of sub-bands within a CSI-RS frequency band. The UE receives second signaling configuring a CSI report associated with the CSI-RS. A network entity (NE) transmits at least one CSI-RS to the UE, and the UE selectively performs at least one measurement on a subset of sub-bands of the set of sub-bands within the CSI-RS frequency band based on the first signaling and the second signaling. The UE transmits third signaling including the CSI report based on the second signaling.

[0002] This disclosure relates to wireless communications, and more specifically, to channel measurement and reporting. Background Technology

[0003] A wireless communication system may include one or more network communication devices, such as base stations, which may support wireless communication with one or more user communication devices, which may also be referred to as user equipment (UE) or other suitable terms. The wireless communication system can support wireless communication with one or more user communication devices by utilizing the resources of the wireless communication system (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers, etc.). Furthermore, the wireless communication system may support wireless communication across various wireless access technologies, including third-generation (3G), fourth-generation (4G), fifth-generation (5G), and other suitable wireless access technologies besides 5G (e.g., sixth-generation (6G)). Summary of the Invention

[0004] The article “a” preceding an element is unrestricted and is understood to refer to “at least one” or “one or more” of those elements. The terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. As used herein, the word “or,” as used in technical solutions, such as in a list of items (e.g., a list of items beginning with phrases such as “at least one of…” or “one or more of…” or “one or two of…”), indicates a list of inclusion, such that a list of at least one of, for example, A, B, or C, means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Additionally, as used herein, the phrase “based on” is not to be construed as referring to a closed set of conditions. For example, without departing from the scope of this disclosure, an instance step described as “based on condition A” may be based on both condition A and condition B. In other words, as used herein, the phrase “based on” can be interpreted in the same way as the phrase “at least partially based on.” Furthermore, as used herein, a “set” may contain one or more elements included in the technical solution.

[0046] A wireless communication system includes one or more means, such as a UE and an NE, for transmitting or receiving signaling. For example, a UE may establish a wireless connection with an NE for transmitting and / or receiving control signaling, data signaling, or both. In some examples, a UE may receive one or more reference signals, such as CSI-RS, from an NE and / or from other means in the wireless communication system. CSI-RS may be a reference signal designed to help estimate CSI at a receiving device (e.g., the UE). The UE may measure one or more characteristics of the CSI-RS, including, but not limited to, Received Signal Strength (RSSI), Channel Quality Indicator (CQI), Reference Signal Received Power (RSRP), or Reference Signal Received Quality (RSRQ). The UE may transmit a CSI report indicating one or more measurements, along with other information, to the NE. The NE may use the information contained in the CSI report (signal strength, modulation and coding scheme (MCS), selected beam, resource allocation, etc.) to adjust one or more transmission parameters used for signaling notifications to and from the UE.

[0047] UE and NE can use communication resources to transmit or receive signaling. For example, UE and / or NE can split (e.g., allocate, distribute) communication resources in the time domain between uplink and downlink transmissions, which can be referred to as a Time Division Duplex (TDD) communication scheme. In a TDD communication scheme, signal transmission and reception occur at different times within the same frequency band, as described in further detail with reference to Figure 3. Different time resources within a transmission frame can be allocated to uplink and / or downlink transmissions, and the transmission frame can be referred to as a time slot and can be further divided into symbols. Alternatively, to reduce latency and achieve higher signaling throughput, NE and / or UE can implement SBFD operation. SBFD operation implements the division of a frequency band into subbands for simultaneous transmission and reception within the same time slot or using the same symbols, as described in Figure 3. Figure 4 Further details are provided. For example, a device (e.g., NE and / or UE) may use a sub-band of a frequency band to receive signaling from one or more other devices, while the device simultaneously (e.g., within the same symbol duration or within the same time slot) uses different sub-bands of the frequency band to transmit signaling to another device.

[0048] The NE can transmit signaling indicating the frequency domain locations of one or more subbands allocated for SBFD communications, such that the frequency domain locations are periodic or aperiodic (e.g., semi-statically configured) over a defined duration. The NE can include one or more resources allocated for corresponding CSI-RS transmissions and / or CSI reports in the signaling, such that CSI-RS resource allocation can be continuous in the frequency domain. However, if the NE dynamically allocates the frequency domain locations of one or more subbands allocated for SBFD communications (e.g., independently of or without periodicity), the resources allocated for CSI-RS transmissions and CSI reports may overlap with the one or more subbands allocated for SBFD communications. The overlap of subbands allocated for SBFD communication and resources allocated for CSI-RS transmission and CSI reporting (e.g., in the frequency domain) may lead to communication errors and / or delays due to the failure to perform one or more CSI-RS measurements and / or CSI reports, as well as increased signaling overhead and / or increased use of communication resources due to CSI-RS retransmissions caused by the failure to perform CSI-RS measurements and / or CSI reports.

[0049] As described herein, to reduce or eliminate overlap between subbands allocated for SBFD communication and resources allocated for CSI-RS transmission and CSI reporting, the NE may transmit signaling to the UE indicating one or more subbands within the CSI-RS band allocated for CSI-RS transmission. The NE may also transmit additional signaling to the UE to configure CSI reporting. For example, the additional signaling may indicate that the CSI report includes CSI-RS measurements, an indication of obtaining measurements by measuring SBFD or non-SBFD time resources, an indication of a subset of subbands, and / or an indication of measurement error states. Alternatively, the additional signaling may indicate that the CSI report includes one or more measured CSI values, an error state including one or more monitoring times for CSI-RS, an indication of one or more frequency resources for the measured CSI values, and / or a measurement technique for obtaining the CSI values. In some examples, the NE and / or another device may use the indicated subband within the CSI-RS band to transmit one or more CSI-RS to the UE. The UE may, according to the relevant information... Figure 2 The standard selectively measures CSI-RS in a further detailed description and can transmit CSI reports to the NE based on additional signaling.

[0050] The aspects of this disclosure are described in the context of wireless communication systems.

[0051] Figure 1 An example of a wireless communication system 100 according to aspects of this disclosure is shown. The wireless communication system 100 may include one or more NEs 102, one or more UEs 104, and a core network (CN) 106. The wireless communication system 100 may support various wireless access technologies. In some embodiments, the wireless communication system 100 may be a 4G network, such as an LTE network or an LTE-A network. In some other embodiments, the wireless communication system 100 may be an NR network, such as a 5G network, a 5G-A network, or a 5G Ultra Wideband (5G-UWB) network. In other embodiments, the wireless communication system 100 may be a combination of 4G and 5G networks, or other suitable wireless access technologies, including IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20. The wireless communication system 100 may support wireless access technologies beyond 5G, such as 6G. In addition, the wireless communication system 100 can support technologies such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), or Code Division Multiple Access (CDMA).

[0052] One or more NEs 102 may be distributed throughout a geographic area to form a wireless communication system 100. The one or more NEs 102 described herein may be, include, or be referred to as a network node, base station, network element, network function, network entity, radio access network (RAN), NodeB, eNodeB (eNB), next-generation NodeB (gNB), or other suitable terms. NEs 102 and UEs 104 may communicate via a communication link, which may be a wireless or wired connection. For example, NEs 102 and UEs 104 may perform wireless communication (e.g., receiving signaling, transmitting signaling) via a Uu interface.

[0053] NE 102 can provide a geographic coverage area, wherein NE 102 can support services for one or more UEs 104 within the geographic coverage area. For example, NE 102 and UE 104 can support wireless communication based on signals associated with one or more radio access technologies and services (e.g., voice, video, packet data, messaging, broadcasting, etc.). In some embodiments, NE 102 can be mobile, for example, a satellite associated with a non-terrestrial network (NTN). In some embodiments, different geographic coverage areas associated with the same or different radio access technologies can overlap, but different geographic coverage areas can be associated with different NEs 102.

[0054] One or more UEs 104 may be distributed throughout the geographic area of ​​the wireless communication system 100. UE 104 may include or be referred to as a remote unit, mobile device, wireless device, remote device, subscriber device, transmitter device, receiver device, or any other suitable term. In some embodiments, UE 104 may be referred to as a unit, station, terminal, or client, among other examples. Additionally or alternatively, UE 104 may be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine Type Communication (MTC) device, among other examples.

[0055] UE 104 may be able to support direct wireless communication with other UE 104 via a communication link. For example, UE 104 may support direct wireless communication with another UE 104 via a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular V2X deployments, the communication link may be referred to as a side link. For example, UE 104 may support direct wireless communication with another UE 104 via a PC5 interface.

[0056] NE 102 may support communication with CN 106, communication with another NE 102, or both. For example, NE 102 may interface with other NE 102 or CN 106 via one or more backhaul links (e.g., S1, N2, N6, or other network interfaces). In some embodiments, NE 102 may communicate directly with each other. In some other embodiments, NE 102 may communicate indirectly with each other (e.g., via CN 106). In some embodiments, one or more NE 102 may include sub-components, such as access network entities, which may be examples of access node controllers (ANCs). The ANC may communicate with one or more UE 104s via one or more other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmit-receive points (TRPs).

[0057] CN 106 can support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. CN106 can be an evolved packet core (EPC) or a 5G core (5GC), which may include control plane entities that manage access and mobility (e.g., Mobility Management Entity (MME), Access and Mobility Management Function (AMF)), and user plane entities that route packets or interconnect to external networks (e.g., Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)). In some implementations, the control plane entities may manage non-access stratum (NAS) functions of one or more UEs 104 served by one or more NEs 102 associated with CN 106, such as mobility, authentication, and bearer management (data bearers, signaling bearers, etc.).

[0058] CN 106 can communicate with the packet data network via one or more backhaul links (e.g., via S1, N2, N6, or other network interfaces). The packet data network may contain an application server. In some implementations, one or more UEs 104 can communicate with the application server. UE 104 can establish a session (e.g., a Protocol Data Unit (PDU) session, etc.) with CN 106 via NE 102. CN 106 can use the established session (e.g., an established PDU session) to route services (e.g., control information, data, etc.) between UE 104 and the application server. A PDU session can be an example of a logical connection between UE 104 and CN 106 (e.g., one or more network functions of CN 106).

[0059] In the wireless communication system 100, NE 102 and UE 104 can use the resources of the wireless communication system 100 (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communication). In some embodiments, NE 102 and UE 104 may support different resource structures. For example, NE 102 and UE 104 may support different frame structures. In some embodiments, such as in 4G, NE 102 and UE 104 may support a single frame structure. In some other embodiments, such as in 5G and other suitable radio access technologies, NE 102 and UE 104 may support various frame structures (i.e., multiple frame structures). NE 102 and UE 104 may support various frame structures based on one or more basic parameters.

[0060] One or more fundamental parameters may be supported in the wireless communication system 100, and the fundamental parameters may include subcarrier spacing and a cyclic prefix. A first fundamental parameter (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some embodiments, the first fundamental parameter (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one time slot per subframe. A second fundamental parameter (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third fundamental parameter (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth fundamental parameter (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth fundamental parameter (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.

[0061] Time intervals for resources (e.g., communication resources) can be organized according to frames (also known as radio frames). Each frame may have a duration, such as 10 milliseconds (ms). In some embodiments, each frame may contain multiple subframes. For example, each frame may contain 10 subframes, and each subframe may have a duration, such as 1 ms. In some embodiments, each frame may have the same duration. In some embodiments, each subframe of a frame may have the same duration.

[0062] Alternatively or concurrently, the time intervals of resources (e.g., communication resources) can be organized according to time slots. For example, a subframe may contain a certain number (e.g., quantity) of time slots. The number of time slots in each subframe may also depend on one or more fundamental parameters supported in the wireless communication system 100. For example, the first, second, third, fourth, and fifth fundamental parameters (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with corresponding subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz can respectively utilize one time slot per subframe, two time slots per subframe, four time slots per subframe, eight time slots per subframe, and 16 time slots per subframe. Each time slot may contain a certain number (e.g., quantity) of symbols (e.g., Orthogonal Frequency Division Multiplexing (OFDM) symbols). In some embodiments, the number (e.g., quantity) of time slots used for a subframe may depend on the fundamental parameters. For a normal cyclic prefix, a time slot may contain 14 symbols. For an extended cyclic prefix (e.g., applicable to a 60 kHz subcarrier spacing), a time slot may contain 12 symbols. The relationship between the number of symbols per time slot for normal and extended cyclic prefixes, the number of time slots per subframe, and the number of time slots per frame may depend on the fundamental parameter. It should be understood that references to the first fundamental parameter (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) can be used interchangeably between subframes and time slots.

[0063] In the wireless communication system 100, the electromagnetic (EM) spectrum can be divided into various categories, frequency bands, frequency channels, etc., based on frequency or wavelength. For example, the wireless communication system 100 may support one or more operating frequency bands, such as frequency range identifiers FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7.125 GHz - 24.25 GHz), FR4 (52.6 GHz - 114.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), and FR5 (114.25 GHz - 300 GHz). In some embodiments, NE 102 and UE 104 may perform wireless communication on one or more of the operating frequency bands. In some embodiments, FR1 may be used by NE 102 and UE 104, as well as other equipment or devices for cellular communication services (e.g., control information, data). In some implementations, FR2 may be used by NE 102 and UE 104, as well as other equipment or devices for short-range high data rate capability.

[0064] FR1 may be associated with one or more fundamental parameters (e.g., at least three fundamental parameters). For example, FR1 may be associated with: a first fundamental parameter (e.g., μ=0) containing a 15 kHz subcarrier spacing; a second fundamental parameter (e.g., μ=1) containing a 30 kHz subcarrier spacing; and a third fundamental parameter (e.g., μ=2) containing a 60 kHz subcarrier spacing. FR2 may be associated with one or more fundamental parameters (e.g., at least two fundamental parameters). For example, FR2 may be associated with: a third fundamental parameter (e.g., μ=2) containing a 60 kHz subcarrier spacing; and a fourth fundamental parameter (e.g., μ=3) containing a 120 kHz subcarrier spacing.

[0065] In some examples, the terms antenna, panel, and antenna panel are used interchangeably. An antenna panel can be hardware for transmitting and / or receiving wireless signals at frequencies below 6 GHz (e.g., FR1) or above 6 GHz (e.g., FR2 or millimeter wave (mmWave)). In some examples, an antenna panel can include an array of antenna elements connected to hardware, such as a phase shifter that provides a control module to apply spatial parameters for transmitting and / or receiving signals. The resulting radiation pattern can be referred to as a beam, which may be single-peaked or non-single-peaked, and can enable a device (e.g., UE 104, node) to amplify signals transmitted or received from one or more spatial directions.

[0066] In some examples, the antenna panel may or may not be virtualized as an antenna port. For each of the transmission (e.g., outgoing) and reception (e.g., incoming) directions, the antenna panel can be connected to the baseband processing module via a radio frequency (RF) chain. The device's capabilities, such as the number of antenna panels, duplex capability, and beamforming capability, may or may not be transparent to other devices. In some examples, capability information may be communicated via signaling, or in some examples, capability information may be provided to the device without signaling. Where such information is available to other devices (e.g., CU), the information can be used for signaling or local decision-making.

[0067] In some examples, the antenna panel may be a physical or logical antenna array comprising a collection of antenna elements or antenna ports sharing a common or significant portion of the RF chain (e.g., in-phase / quadrature (I / Q) modulators, analog-to-digital (A / D) converters, local oscillators, phase-shift networks). The antenna panel may be a logical entity having physical antennas mapped to logical entities. The mapping from physical antennas to logical entities may vary depending on the implementation. Communication (e.g., receiving or transmitting) on ​​at least a subset of the radiated energy-active antenna elements or antenna ports (also referred to herein as active elements) of the antenna panel involves biasing or energizing the RF chain, resulting in current consumption or power consumption at devices (e.g., nodes) associated with the antenna panel (e.g., power consumption of power amplifiers and / or low-noise amplifiers (LNAs) associated with the antenna elements or antenna ports). As used herein, the phrase "radiated energy-active" is not intended to be limited to transmission functions but also covers reception functions. Therefore, active antenna elements that radiate energy can be coupled simultaneously or sequentially to a transmitter to transmit RF energy or to a receiver to receive RF energy, or they can typically be coupled to a transceiver to perform the intended functionality. Communication on the active elements of the antenna panel enables the generation of radiation patterns or beams.

[0068] In some examples, depending on the implementation, a "panel" may have at least one of the following functionalities: an operational role as a unit of an antenna group that independently controls the transmit beam, an antenna group that independently controls the transmit power, and an antenna group that independently controls the transmission timing. The "panel" may be transparent to another node (e.g., a next-hop neighbor). For one or more conditions, another node or network entity may assume that the mapping between the device's physical antennas and the logical entity "panel" will not change. For example, the condition may include a duration until the next update or report from the device, or a duration during which NE 102 assumes the mapping will not change. The device may report its device capabilities regarding the "plane" to NE 102. Device capabilities may include at least the number of "panels". In some implementations, the device may support transmission from a single beam within the panel. In some cases, for multiple panels, more than one beam (e.g., one beam per panel) may be available for transmission. In some other implementations, more than one beam per panel may be supported and / or used for transmission.

[0069] In some examples, an antenna port is defined such that a channel transmitting a symbol on that antenna port can be inferred from a channel transmitting another symbol on the same antenna port. Two antenna ports are said to be quasi-co-located (QCL) if the large-scale characteristics of a channel transmitting a symbol on one antenna port can be inferred from a channel transmitting a symbol on another antenna port. Large-scale characteristics include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial reception parameters. Two antenna ports can be quasi-co-located relative to a subset of large-scale characteristics, and different subsets of large-scale characteristics can be indicated by the QCL type. The QCL type can indicate which channel characteristics are the same between two reference signals (e.g., on the two antenna ports). Therefore, reference signals can be linked to each other relative to what the device can assume about its channel statistics or QCL characteristics. For example, the QCL type can take one of the following values. Other QCL types can be defined based on one or a combination of large-scale characteristics, including, but not limited to, QCL-TypeA, QCL-TypeB, QCL-TypeC, and QCL-TypeD. QCL-Type A may include Doppler shift, Doppler spread, average delay, and / or delay spread. QCL-Type B may include Doppler shift and / or Doppler spread. QCL-Type C may include Doppler shift and / or average delay. QCL-Type D may include spatial reception or reception parameters. Spatial reception or reception parameters may include one or more of the following: angle of arrival (AoA), primary AoA, average AoA, angular spread, power angular spectrum (PAS) of AoA, average angle of departure (AoD), PAS of AoD, transmit / receive channel correlation, transmit / receive beamforming, and spatial channel correlation. QCL-Type A, QCL-Type B, and QCL-Type C may be applicable to carrier frequencies, but QCL-Type D may be applicable to higher carrier frequencies (e.g., mmWave, FR2, and beyond), where the device may not be able to perform omnidirectional transmission (e.g., the device will form a beam for directional transmission). QCL-Type D between two reference signals A and B, where reference signal A is considered spatially co-located with reference signal B, and the device can determine that reference signals A and B can be received using the same spatial filter (e.g., with the same receive beamforming weights).

[0070] An "antenna port" can be a logical port that corresponds to a beam (e.g., generated by beamforming) or a physical antenna on the device. In some examples, a physical antenna can be directly mapped to a single antenna port, where the antenna port corresponds to the physical antenna. Alternatively or alternatively, after applying complex weights, cyclic delays, or both to the signal on each physical antenna, a set or subset of physical antennas, or an antenna array or antenna subarray, can be mapped to one or more antenna ports. The set of physical antennas can have antennas from a single module or panel, or from multiple modules or panels. Weights can be fixed, such as in antenna virtualization schemes, for example, cyclic delay diversity (CDD). The procedure used to derive the antenna port from the physical antenna can be device-specific and transparent to other devices.

[0071] In some cases, the Transport Configuration Indicator (TCI) state associated with the target transmission may indicate parameters for configuring the QCL relationship between the target transmission (e.g., the target reference signal of the demodulation reference signal (DMRS) port of the target transmission during the transmission timing) and one or more source reference signals (e.g., synchronization signal block (SSB), CSI-RS, and / or probe reference signal (SRS)) with respect to the QCL type parameters indicated in the corresponding TCI state. The TCI describes which reference signals are used as QCL sources and what QCL characteristics can be derived from each reference signal. The apparatus may receive a configuration of the TCI state set for the serving cell to perform transmissions on the serving cell (e.g., between the serving gNB and the smart repeater). In some examples, the TCI state includes at least one source reference signal to provide a reference for determining the QCL and / or spatial filtering.

[0072] In some cases, if the device is configured with separate downlink and / or uplink TCIs via Radio Resource Control (RRC) signaling, an uplink TCI state is provided. The uplink TCI state may include a source reference signal that provides a reference for determining the uplink spatial domain transmission filter (e.g., based on dynamically licensed / configured licensed Physical Uplink Shared Channel (PUSCH), Dedicated Physical Uplink Control Channel (PUCCH) resources) for uplink transmission in component carriers (CCs) or across configured CCs and / or bandwidth portions (BWPs) sets. In some cases, if the device is configured with joint downlink and / or uplink TCIs via RRC signaling (e.g., configuration of joint TCI or separate downlink and / or uplink TCIs based on RRC signaling), a joint downlink and / or uplink TCI state is provided. The combined downlink and / or uplink TCI state refers at least to a common source reference signal used to determine both downlink QCL information and uplink spatial transmission filters. A QCL type D indication (e.g., for device-specific Physical Downlink Control Channel (PDCCH) and / or Physical Downlink Shared Channel (PDSCH)) is provided based on the source reference signal determined according to the indicated joint or common TCI state, and is used to determine the uplink spatial transmission filter (e.g., for UE-specific PUSCH and / or PUCCH) for CC or across a configured CC and / or BWP set. In some examples, the uplink spatial transmission filter is derived from the reference signal of downlink QCL type D in the joint TCI state. The spatial setting of uplink transmission may be set to 'QCL-typeD' in the joint TCI state based on the spatial relationship with the reference to the source reference signal configured with the QCL type.

[0073] In some cases, spatial relation information associated with the target transmission can indicate parameters for configuring the spatial settings between the target transmission and reference signals (e.g., SSB, CSI-RS, and / or SRS). For example, the apparatus may use the same spatial domain filter used to receive the reference signal (e.g., a downlink reference signal containing SSB and / or CSI-RS) to transmit the target transmission. In some other examples, the apparatus may use the same spatial domain transmission filter used to transmit the reference signal (e.g., an uplink reference signal containing SRS) to transmit the target transmission. The UE may receive configurations for configuring multiple spatial relation information for the serving cell for transmission on the serving cell.

[0074] In some cases, if the device is configured with separate downlink and / or uplink TCIs via RRC signaling, an uplink TCI state is provided. The uplink TCI state may include a source reference signal that provides a reference for determining the uplink spatial domain transmission filter for uplink transmissions in or across configured CCs and / or BWP sets (e.g., based on dynamically licensed and / or configured licensed PUSCH, dedicated PUCCH resources). In some cases, if the device is configured with combined downlink and / or uplink TCIs via RRC signaling (e.g., combined TCI or separate downlink and / or uplink TCI configuration based on RRC signaling), a combined downlink and / or uplink TCI state is provided. The combined downlink and / or uplink TCI state refers at least to a common source reference signal used to determine both downlink QCL information and uplink spatial transmission filters. A QCL type D indication (e.g., for device-specific PDCCH and / or PDSCH) is provided based on the source reference signal determined according to the indicated joint or common TCI state, and is used to determine the uplink spatial transmission filter (e.g., for UE-specific PUSCH and / or PUCCH) for CC or across a configured CC and / or BWP set. In one example, the uplink spatial transmission filter is derived from the downlink QCL type D reference signal in the joint TCI state. The spatial setting of the uplink transmission can be set to 'QCL-typeD' in the joint TCI state based on the spatial relationship with the reference to the source reference signal configured with the QCL type.

[0075] In some examples, NE 102 can configure UE 104 to report information to NE 102 in uplink signaling. For example, NE 102 can instruct UE 104 to transmit aperiodic CSI reports. In variations, CSI reports are triggered by control signaling, such as downlink control information (DCI) format 0_1 ​​messages, DCI format 0_2 messages (e.g., by applying the higher-layer parameter reportTriggerSizeDCI-0-2 instead of reportTriggerSize), and / or DCI format 0_3 messages. In some cases, NE 102 can control one or more time and frequency resources that can be used by UE 104 to report CSI. Example CSIs may include, but are not limited to, CQI, Precoding Matrix Indicator (PMI), CSI-RS Resource Indicator (CRI), Synchronization Signal and / or Physical Broadcast Channel (PBCH) Block Resource Indicator (SSBRI), Layer Indicator (LI), Rank Indicator (RI), L1-RSRP, L1-Signal-Interference-Noise Ratio (SINR), Capability Index parameter (e.g., CapabilityIndex), and / or one or more Time-Domain Channel Characteristics (TDCP). For CQI, PMI, CRI, SSBRI, LI, RI, L1-RSRP, L1-SINR, CapabilityIndex, and / or TDCP, UE 104 is configured by a higher layer with one or more parameters and / or configurations (e.g., N ≥ 1 CSI-ReportConfig reporting settings, X ≥ 1 LTM-CSI-ReportConfig reporting settings, M ≥ 1 CSI-ResourceConfig resource settings, and / or Y ≥ 1 LTM-CSI-ResourceConfig resource settings) and one or more trigger state lists.

[0076] In variations, the trigger state list may be indicated by one or more higher-level parameters (e.g., CSI-AperiodicTriggerStateList and CSI-SemiPersistentOnPUSCH-TriggerStateList). The trigger states in the list (e.g., CSI-AperiodicTriggerStateList) contain a list of associated CSI reporting configuration parameters (e.g., CSI-ReportConfigs or LTM-CSI-ReportConfigs) indicating resource set identifiers (IDs) for the channel and optionally for interference. Configuration parameters may include L1 and / or L2 triggered mobility (LMT) CSI reporting configuration parameters. In some cases, resource sets for interference may exist for the reporting settings given by the CSI reporting configuration parameters (e.g., CSI-ReportConfig). Alternatively or additionally, if the associated CSI reporting configuration parameter (e.g., CSI-ReportConfig) is configured with a sub-configuration list, the trigger state contains one or more ID parameters (e.g., csi-ReportSubConfigID). The trigger states in the list (e.g., CSI-SemiPersistentOnPUSCH-TriggerStateList) may contain associated CSI report configurations (e.g., CSI-ReportConfig or LTM-CSI-ReportConfig), and if the associated CSI report configuration parameter (e.g., CSI-ReportConfig) is configured with a list of sub-configurations, the trigger states may additionally or alternatively contain one or more ID parameters (e.g., csi-ReportSubConfigID).

[0077] In some examples, reporting settings (e.g., CSI-ReportConfig) are associated with a single downlink BWP, which may be indicated by higher-layer parameters (e.g., BWP-Id) given in the associated CSI-ResourceConfig for channel measurements, and includes one or more parameters for the CSI reporting band. Parameters for CSI reporting may include, but are not limited to: codebook configuration including codebook subset restrictions, time-domain behavior, frequency granularity for CQI and / or PMI, measurement restriction configuration, and CSI-related quantities to be reported by UE 104, such as LI, L1-RSRP, L1-SINR, CRI, SSBRI, CapabilityIndex, and TDCP. Report settings (e.g., LTM-CSI-ReportConfig) may be associated with resource configurations used for channel measurements (e.g., LTM-CSI-ResourceConfig) and may include one or more parameters for time-domain behavior (e.g., provided by ltm-ReportConfigType), numerical values ​​for the cell, and numerical values ​​for the reference signal for each candidate cell (e.g., provided by noOfReportedCells and noOfReportedRS-PerCell, respectively), including L1 measurement results associated with the current cell (e.g., SpCell if spCellInclusion is configured).

[0078] In some examples, the time-domain behavior of CSI-ReportConfig is indicated by the higher-layer parameter reportConfigType, and may have a value set to at least one of 'aperiodic', 'semi-persistent on PUCCH', 'semi-persistent on PUSCH', or 'periodic'. For 'periodic', 'semi-persistent on PUCCH', and / or semi-persistent on PUSCH CSI reports, the configured periodicity and slot offset apply to the underlying parameters of the uplink BWP on which the CSI report is configured to be transmitted. Higher-layer parameters (e.g., reportQuantity) indicate the CSI-related quantity, L1-RSRP-related quantity, L1-SINR-related quantity, capability index-related quantity, or TDCP-related quantity to be reported. Parameters (e.g., reportFreqConfiguration) indicate the reporting granularity in the frequency domain, including the CSI reporting band and whether the PMI and / or CQI report is wideband or subband. Parameters in the CSI reporting configuration (e.g., CSI-ReportConfig) such as `timeRestrictionForChannelMeasurements` can be configured to enable time-domain restriction of channel measurements, and parameters such as `timeRestrictionForInterferenceMeasurements` can be configured to enable time-domain restriction of interference measurements. The CSI reporting configuration (e.g., CSI-ReportConfig) may also include: a codebook configuration (e.g., CodebookConfig) containing configuration parameters for: Type I, Type II, Enhanced Type II CSI, Further Enhanced Type II Port Selection, Enhanced Type II for Coherent Joint Transmission (CJT), Further Enhanced Type II Port Selection for CJT, Enhanced Type II for Predicted PMI, or Further Enhanced Type II Port Selection for Predicted PMI (including codebook subset restrictions where applicable); and a group-based reporting configuration.

[0079] In some examples, if the value of the `reportConfigType` parameter is set to aperiodic, UE 104 may not be configured with CSI reporting settings associated with the sleeping downlink BWP. A CSI reporting configuration (e.g., `CSI-ReportConfig`) may contain a list of sub-configurations provided by a higher-layer parameter (e.g., `csi-ReportSubConfigList`), where sub-configurations are identified by a parameter (e.g., `csi-ReportSubConfigID`) and correspond to a list of one or more CSI-RS resources or a subset of CSI-RS antenna ports, and / or, in addition to the power control offset of the CSI-RS resources, also correspond to the power offset of the PDSCH relative to the CSI-RS. UE 104 may not be configured with a CSI reporting configuration (e.g., `CSI-ReportConfig`) that contains a mixture of sub-configurations corresponding to a list of one or more CSI-RS resources and some other sub-configurations corresponding to a subset of CSI-RS antenna ports. In some examples, the time-domain behavior of the LTM CSI report configuration (e.g., LTM-CSI-ReportConfig) is indicated by a higher-layer parameter (e.g., ltm-ReportConfigType) and can be set to a value of 'aperiodic', 'semi-PersistentOnPUCCH', 'semi-PersistentOnPUSCH', or 'periodic'. For periodic, semi-PersistentOnPUCCH, and / or semi-PersistentOnPUSCH CSI reports, the configured periodicity and slot offset apply to the underlying parameters of the uplink BWP on which the CSI report is configured to be transmitted.

[0080] A CSI resource setting (e.g., CSI-ResourceConfig) contains a configuration of a list of S ≥ 1 CSI resource sets (e.g., given by the higher-layer parameter csi-RS-ResourceSetList), where the list contains references to any one or both of the non-zero power (NZP) CSI-RS resource set and the synchronization signal and / or PBCH block set, or the list contains references to the CSI-Interference Measurement (IM) resource set. The CSI resource setting resides in a downlink BWP identified by the higher-layer parameter BWP-id, and CSI resource settings linked to the CSI reporting setting may have the same downlink BWP.

[0081] The temporal behavior of CSI-RS resources within the CSI resource settings is indicated by higher-layer parameters (e.g., resourceType) and can be set to aperiodic, periodic, or semi-persistent. For periodic and semi-persistent CSI resource settings, when UE 104 is configured with group-based beam reporting (e.g., groupBasedBeamReporting-r17 or groupBasedBeamReporting-v18), the value of the configured CSI resource set is S=2; otherwise, the value of the configured CSI-RS resource set is S=1. In addition to periodic CSI resource settings, when UE 104 is configured with TDCP reporting, the value of the CSI-RS resource set in the CSI resource settings used for channel measurements is K_TRS. {1,2,3} and the CSI-RS resource set is configured with higher-layer parameters (e.g., trs-Info). For periodic and semi-persistent CSI resource settings, the configured periodicity and slot offset are given in the base parameters of their associated downlink BWP, such as by BWP-id. When UE104 is configured with multiple CSI-ResourceConfigs containing the same NZPCSI-RS resource ID, the same temporal behavior can be configured for the CSI-ResourceConfigs. When UE104 is configured with multiple CSI-ResourceConfigs containing the same CSI-IM resource ID, the same temporal behavior can be configured for the CSI-ResourceConfigs. One or more CSI resource settings linked to CSI reporting settings can have the same temporal behavior.

[0082] In some examples, NE 102 can configure one or more CSI resource settings for channel and interference measurements via higher-layer signaling. For example, NE 102 can configure a CSI-IM resource for interference measurement, an NZPCSI-RS resource for interference measurement, and / or an NZP CSI-RS resource for channel measurement. In some examples, UE 104 can determine that the NZP CSI-RS resource for channel measurement and the CSI-IM resource for interference measurement configured for a CSI report are QCLed relative to 'typeD' on a resource-by-resource basis. When the NZP CSI-RS resource is used for interference measurement, UE 104 can determine that the NZP CSI-RS resource for channel measurement and the CSI-IM resource for interference measurement configured for a CSI report, or the NZP CSI-RS resource, are QCLed relative to 'typeD'.

[0083] In some cases, such as for TDCP measurements, periodic CSI resource settings are configured, and these resource settings are used for channel measurements of the CSI-RS for tracking. For L1-SINR measurements, when resource settings are configured, these settings (e.g., given by the higher-layer parameter resourcesForChannelMeasurement) can be used for both channel and interference measurements of the NZP CSI-RS used for L1-SINR calculation. In some cases, UE 104 may determine that the same 1-port NZP CSI-RS with density 3 resource elements (REs) and / or resource blocks (RBs) is used for both channel and interference measurements. When two resource settings are configured, the first resource setting (e.g., given by the higher-layer parameter resourcesForChannelMeasurement) can be used for channel measurements on SSB or NZP CSI-RS, and the second resource setting (e.g., given by the higher-layer parameter csi-IM-ResourcesForInterference or the higher-layer parameter nzp-CSI-RS-ResourcesForInterference) can be used for interference measurements performed on CSI-IM or on a 1-port NZP CSI-RS with a density of 3 Re and / or RB. The SSB or NZP CSI-RS resource used for channel measurements is associated with a CSI-IM resource or an NZP CSI-RS resource used for interference measurements by sorting the SSB or NZP CSI-RS resources used for channel measurements and the CSI-IM or NZP CSI-RS resources used for interference measurements in the corresponding resource set. The numerical value of the SSB or CSI-RS resource used for channel measurements may be equal to the numerical value of the CSI-IM resource or the NZP CSI-RS resource used for interference measurements.

[0084] In some examples, UE 104 may apply an SSB or a 'typeD' reference configured with a qcl-Type set to 'typeD' to the NZP CSI-RS resource used for channel measurements as a reference signal for determining the corresponding CSI-IM resource or the corresponding NZP CSI-RS resource configured for interference measurements for a CSI report. UE 104 may determine that the NZP CSI-RS resource used for channel measurements and the NZP-CSI-RS resource set used for interference measurements (if present) are configured with the higher-layer parameter repetition. The LTM CSI resource settings (e.g., LTM-CSI-ResourceConfig) may contain a configuration of a resource set (e.g., LTM-CSI-SSB-ResourceSet), which may contain a list of Z≥1 synchronization signal and / or PBCH block indices (e.g., given by ltm-CSI-SSB-ResourceList) and a list of Z (e.g., LTM-CandidateIds given by ltm-CandidateIDList) referring to candidate cells associated with the synchronization signal and / or PBCH block indices. For each candidate cell, UE 104 may determine the temporal behavior of the synchronization signal and / or PBCH block based on one or more parameters (e.g., ssb-Periodicity and ssb-PositionsInBurst) and the frequency domain behavior of the synchronization signal and / or PBCH block through one or more higher-layer parameters (e.g., subCarrierSpacing, ssbFrequency).

[0085] In some examples, UE 104 may calculate CSI parameters based on one or more dependencies between CSI parameters. For example, LI may be calculated based on reported CQI, PMI, RI, and CRI. Alternatively, CQI may be calculated based on reported PMI, RI, and CRI. Alternatively, PMI may be calculated based on reported RI and CRI. Alternatively, RI may be calculated based on reported CRI. The reporting configuration for CSI may be aperiodic (e.g., using PUSCH), periodic (e.g., using PUCCH), or semi-persistent (e.g., using PUCCH and DCI-activated PUSCH). CSI-RS resources may be periodic, semi-persistent, or aperiodic. Periodic CSI-RS are configured by higher layers. Semi-persistent CSI-RS are activated and deactivated. Aperiodic CSI-RS are configured, triggered, and / or activated. When UE 104 is configured with the higher-layer parameter NZP-CSI-RS-ResourceSet and the higher-layer parameter repetition is set to 'Off', UE 104 can determine the CRI from the supported set of CRI values ​​and report the number in the CRI report. When the higher-layer parameter repetition for the CSI-RS resource set used for channel measurements is set to 'On', the CRI for the CSI-RS resource set used for channel measurements is not reported. CRI reporting is not supported when the higher-layer parameter codebookType can be set to values ​​(e.g., 'typeII', 'typeII-PortSelection', 'typeII-r16', 'typeII-PortSelection-r16', 'typeII-PortSelection-r17', 'typeII-CJT-r18', 'typeII-CJT-PortSelection-r18', 'typeII-Doppler-r18' and / or 'typeII-Doppler-PortSelection-r18').

[0086] In some cases, such as for semi-persistent or non-periodic CSI reports on PUSCH, slot offsets can be configured by one or more higher-level parameters. For example, if triggered and / or activated by DCI format 0_2 and configured with the higher-level parameter reportSlotOffsetListDCI-0-2 or reportSlotOffsetListDCI-0-2-r17, the slot offset is configured by reportSlotOffsetListDCI-0-2 or reportSlotOffsetListDCI-0-2-r17; and if triggered and / or activated by DCI format 0_1 ​​or 0_3 and configured with the higher-level parameter reportSlotOffsetListDCI-0-1 or reportSlotOffsetListDCI-0-1-r17, the slot offset is configured by reportSlotOffsetListDCI-0-1 or reportSlotOffsetListDCI-0-1-r17; otherwise, the slot offset is configured by the higher-level parameter reportSlotOffsetList or reportSlotOffsetList-r17.

[0087] In some examples, the offset is selected upon activation and / or triggering of DCI. For CSI reporting, UE 104 can be configured via higher-layer signaling with subband size, where subbands are defined as a set of consecutive PRBs and depend on the total number of PRBs in the BWP. The reportFreqConfiguration included in the CSI reporting configuration (e.g., CSI-ReportConfig) indicates the frequency granularity of CSI reporting. The CSI reporting setting configuration defines the CSI reporting band as a subset of the subbands of the BWP. The reportFreqConfiguration indicates the csi-ReportingBand as a consecutive or non-consecutive subset of the CSI-reportable subbands in the BWP. UE 104 may not be configured with a csi-ReportingBand containing subbands, where the frequency density of the CSI-RS resources linked to the CSI reporting setting per CSI-RS port per PRB in the subband is less than the configured density of the CSI-RS resources. If the CSI-IM resource is linked to the CSI reporting settings, UE 104 may not be configured with a csi-ReportingBand containing subbands, where not all PRBs in the subband have a CSI-IM RE. UE 104 can be configured via higher-layer signaling with wideband CQI or subband CQI reporting, such as by the higher-layer parameter cqi-FormatIndicator. In some examples, when wideband CQI reporting is configured, wideband CQI is reported for codewords in the CSI reporting band. When subband CQI reporting is configured, one CQI is reported for each codeword in the corresponding subband within the CSI reporting band. UE 104 can also be configured via higher-layer signaling with wideband PMI or subband PMI reporting, such as by the higher-layer parameter pmi-FormatIndicator. When wideband PMI reporting is configured, wideband PMI is reported for the CSI reporting band. When subband PMI reporting is configured, in addition to the two antenna ports, a single bandwidth is reported for the CSI reporting band, and a subband indication is reported for the corresponding subband within the CSI reporting band. When subband PMI is configured with two antenna ports, PMI is reported for the corresponding subband within the CSI reporting band.

[0088] In some examples, if codebookType is set to 'typeII-r16', 'typeII-PortSelection-r16', 'typeII-PortSelection-r17', 'typeII-CJT-r18', 'typeII-CJT-PortSelection-r18', 'typeII-Doppler-r18', or 'typeII-Doppler-PortSelection-r18', then UE 104 may not be configured with pmi-FormatIndicator. If reportQuantity is set to 'cri-RI-PMI-CQI' or 'cri-RI-LI-PMI-CQI', cqi-FormatIndicator is set to 'widebandCQI' and pmi-FormatIndicator is set to 'widebandPMI', or reportQuantity is set to 'cri-RI-PMI-CQI', codebookType is set to 'typeII-PortSelection-r17', 'typeII-CJT-PortSelection-r18', or 'typeII-Doppler-PortSelection-r18', where M=1, and cqi-FormatIndicator is set to 'widebandCQI', or reportQuantity is set to 'cri-RI-PMI-CQI', codebookType is set to 'typeII-PortSelection-r17', 'typeII-CJT-PortSelection-r18', or reportQuantity is set to 'typeII-Doppler-PortSelection-r18', where M=1, and cqi-FormatIndicator is set to 'widebandCQI', or reportQuantity is set to 'typeII-PMI-CQI', codebookType is set to 'typeII-PortSelection-r17', 'typeII-CJT-PortSelection-r18', or reportQuantity is set to 'typeII-PMI-CQI', codebookType ... If tQuantity is set to 'cri-RI-i1' or reportQuantity is set to 'cri-RI-CQI' or 'cri-RI-i1-CQI' and cqi-FormatIndicator is set to 'widebandCQI', or reportQuantity is set to 'cri-RSRP' or 'ssb-Index-RSRP' or 'cri-SINR' or 'ssb-Index-SINR' or 'cri-RSRP-Index' or 'ssb-Index-RSRP-Index' or 'cri-SINR-Index' or 'ssb-Index-SINR-Index', or reportQuantity is set to 'tdcp', then the CSI reporting settings are said to have wideband frequency granularity; otherwise, the CSI reporting settings have subband granularity.

[0089] If UE 104 is configured with CSI reporting settings for a BWP with fewer than 24 PRBs, the CSI reporting settings can have wideband frequency granularity, and if applicable, the higher-layer parameter codebookType is set to 'typeI-SinglePanel'. If UE 104 is configured with semi-persistent CSI reporting, UE 104 can report CSI when both CSI-IM and NZP CSI-RS resources are configured as periodic or semi-persistent. If UE 104 is configured with aperiodic CSI reporting, UE 104 can report CSI when both CSI-IM and NZP CSI-RS resources are configured as periodic, semi-persistent, or aperiodic. UE 104 configured with DCI formats 0_1, 0_2, or 0_3 may not be triggered by multiple CSI reports with the same CSI-ReportConfigId.

[0090] In some cases, for aperiodic CSI, the trigger state configured using the higher-layer parameter CSI-AperiodicTriggerState can be associated with one or more CSI reporting configurations (e.g., CSI-ReportConfig), where CSI reporting configurations not configured with group-based beam reporting (e.g., groupBasedBeamReporting-r17 or groupBasedBeamReporting-v18) are linked to periodic, semi-persistent, or aperiodic resource settings. When a resource setting is configured, the resource setting (e.g., given by the higher-layer parameter resourcesForChannelMeasurement) can be used for channel measurements of L1-RSRP or for channel and interference measurements for L1-SINR calculation. When two resource settings are configured, the first resource setting (e.g., given by the higher-layer parameter resourcesForChannelMeasurement) can be used for channel measurements, and the second resource setting (e.g., given by the higher-layer parameter csi-IM-ResourcesForInterference or the higher-layer parameter nzp-CSI-RS-ResourcesForInterference) can be used for interference measurements performed on CSI-IM or NZP CSI-RS. When three resource settings are configured, the first resource setting (e.g., the higher-layer parameter resourcesForChannelMeasurement) can be used for channel measurements, the second resource setting (e.g., given by the higher-layer parameter csi-IM-ResourcesForInterference) can be used for CSI-IM-based interference measurements, and the third resource setting (e.g., given by the higher-layer parameter nzp-CSI-RS-ResourcesForInterference) can be used for NZP CSI-RS-based interference measurements.

[0091] For aperiodic CSI and for periodic and semi-persistent CSI resource settings, the trigger state configured using the higher-level parameter CSI-AperiodicTriggerState can be associated with one or more CSI reporting configurations (e.g., CSI-ReportConfig), where CSI reporting configurations configured with group-based beam reporting (e.g., groupBasedBeamReporting-r17 or groupBasedBeamReporting-v18) are linked to the periodic or semi-persistent setting. When configuring a resource setting, the resource setting is given by resourcesForChannelMeasurement for L1-RSRP measurements. In some examples, the numerical value of the configured CSI resource set in the resource setting is S=2. For aperiodic CSI and for aperiodic CSI resource settings, the trigger state configured using the higher-level parameter CSI-AperiodicTriggerState can be associated with one or more CSI report configurations (e.g., CSI-ReportConfig), where a CSI report configuration configured with group-based beam reporting can be associated with resourcesForChannel and resourcesForChannel2, which correspond to the first resource set and the second resource set, respectively, for L1-RSRP measurements.

[0092] In some examples, for semi-persistent or periodic CSI, the CSI reporting configuration (e.g., CSI-ReportConfig) is linked to a periodic or semi-persistent resource setting. When a resource setting is configured (e.g., given by a higher-layer parameter called resourcesForChannelMeasurement), the resource setting is used for channel measurements of L1-RSRP or for both channel and interference measurements for L1-SINR calculation. When two resource settings are configured, the first resource setting (e.g., given by a higher-layer parameter called resourcesForChannelMeasurement) is used for channel measurements, and the second resource setting (e.g., given by a higher-layer parameter called csi-IM-ResourcesForInterference) is used for interference measurements performed on CSI-IM. For L1-SINR calculation, the second resource setting (e.g., given by a higher-layer parameter called csi-IM-ResourcesForInterference or a higher-layer parameter called nzp-CSI-RS-ResourceForInterference) is used for interference measurements performed on CSI-IM or NZP CSI-RS.

[0093] For non-periodic CSI, a UE 104 configured with a CSI-ReportConfig having a higher-layer parameter reportQuantity set to 'tdcp' can be configured with a CSI resource setting (e.g., given by the higher-layer parameter resourcesForChannelMeasurement). The CSI resource setting can be periodic, where K_TRS {1,2,3} CSI-RS resource sets are configured with the higher-layer parameter trs-Info. Support for K_TRS=2 or 3 is subject to UE capability indication. For periodic CSI-ResourceConfig, UE 104 can determine that the CSI-RS resources in K_TRS CSI-RS resource sets share the same QCL-TypeA / C, and, if applicable, TypeD. UE 104 can determine that the CSI-RS resources in the CSI-RS resource sets are configured with the same bandwidth and subcarrier location. UE 104 configured with CSI-ReportConfig having the higher-layer parameter reportQuantity set to 'tdcp' may not be configured with interference measurements for CSI-IM and / or NZP-CSI-RS.

[0094] In some examples, for UE104 configured with a CSI reporting configuration (e.g., LTM-CSI-ReportConfig), aperiodic, semi-persistent, or periodic CSIs are associated with a resource setting given by a parameter for L1-RSRP measurements (e.g., ltm-ResourcesForChannelMeasurement). UE104 may not be configured with more than one CSI-RS resource in the channel measurement resource set for CSI-ReportConfig, where the higher-layer parameter codebookType is set to 'typeII', 'typeII-PortSelection', 'typeII-r16', 'typeII-PortSelection-r16', or 'typeII-PortSelection-r17'. UE 104 may not be configured with more than 64 NZP CSI-RS resources and / or synchronization signals and / or PBCH block resources in the channel measurement resource settings for CSI-ReportConfig, where the higher-layer parameter reportQuantity is set to 'none', 'cri-RI-CQI', 'cri-RSRP', 'ssb-Index-RSRP', 'cri-SINR', or 'ssb-Index-SINR', 'cri-RSRP-Index', 'ssb-Index-RSRP-Index', 'cri-SINR-Index', or 'ssb-Index-SINR-Index'. If interference measurements are performed on CSI-IM, the CSI-RS resources used for channel measurements are associated with the CSI-IM resources on a resource-by-resource basis by sorting the CSI-RS and CSI-IM resources in the corresponding resource sets. The numerical value of the CSI-RS resources used for channel measurements is equal to the numerical value of the CSI-IM resources.

[0095] A UE 104 configured with a CSI-ReportConfig having a higher-layer parameter reportQuantity set to 'cri-RI-PMI-CQI' and a codebookType set to 'typeII-CJT-r18' or 'typeII-CJT-PortSelection-r18' can be configured with 1 ≤ K ≤ 4 CSI-RS resources in the resource set for channel measurements. If interference measurements are performed on CSI-IM, one resource is configured in the corresponding csi-IM-ResourceSet. If interference measurements are performed on NZP CSI-RS, one resource is configured in the corresponding NZP-CSI-RS-ResourceSet for interference measurements. A UE 104 configured with a CSI-ReportConfig having a higher-layer parameter N4 set to 'cri-RI-PMI-CQI' and reportQuantity can be configured with K {4, 8, 12} aperiodic CSI-RS resources or a single periodic or semi-persistent CSI-RS resource configured in a resource set for channel measurements. For the aperiodic CSI-RS resource set used for channel measurements, K CSI-RS resources are triggered by the same trigger instance, and the interval between two consecutive CSI-RS resources is m. {1,2} time slots are configured by higher-layer parameters in the NZP-CSI-RS-ResourceSet. K aperiodic CSI-RS resources are transmitted in the order of CSI-RS resource IDs configured in the CSI-RS resource set. UE 104 can determine that the antenna ports with the same port index of the K aperiodic CSI-RS resources are identical. If interference measurement is performed on CSI-IM, a resource is configured in the corresponding csi-IM-ResourceSet. If interference measurement is performed on NZP CSI-RS, a resource is configured in the corresponding NZP-CSI-RS-ResourceSet used for interference measurement.

[0096] An NZP CSI-RS resource set for channel measurements with 2 ≤ K_s ≤ 8 resources can be configured with two resource groups, where K_1 ≥ 1 resource is in group 1 and K_2 ≥ 1 resource is in group 2, such that K_1 + K_2 = K_s, and has N {1,2} resource pairs. A resource pair may contain one resource from group 1 and one resource from group 2. The same resource may be associated with two resource pairs in frequency range 1 but not in frequency range 2. If the corresponding sub-configuration contains a list of one or more NZP CSI-RS resources, then the resource subset of the NZP CSI-RS resource set used for channel measurements (where the subset contains one or more resources) corresponds to the sub-configuration contained in CSI-ReportConfig; otherwise, if the corresponding sub-configuration does not contain a list of NZP CSI-RS resources, then the resources of the NZP CSI-RS resource set used for channel measurements correspond to the corresponding sub-configuration contained in CSI-ReportConfig.

[0097] In addition to L1-SINR, if codebookType is set to 'typeII-CJT-r18', 'typeII-CJT-PortSelection-r18', 'typeII-Doppler-r18', or 'typeII-Doppler-PortSelection-r18', UE 104 may not be configured with more than one NZP CSI-RS resource in the associated resource set within the resource settings for channel measurements if interference measurements are performed on NZP CSI-RS. In addition to L1-SINR, UE 104 configured with the higher-layer parameter nzp-CSI-RS-ResourcesForInterference can determine that no more than 18 NZP CSI-RS ports are configured in the NZP CSI-RS resource set. For CSI measurements other than L1-SINR, UE 104 can determine the corresponding NZP CSI-RS port configured for interference measurements corresponding to the interference transport layer. The interference transport layer on the NZP CSI-RS port used for interference measurements takes into account the associated energy per resource element (EPRE) ratio, and / or other interference signals on the RE of the NZP CSI-RS resource used for channel measurements, the NZP CSI-RS resource used for interference measurements, or the CSI-IM resource used for interference measurements.

[0098] For L1-SINR measurements with dedicated interference measurement resources, UE 104 can determine that the total received power on the dedicated NZP CSI-RS resource or the dedicated CSI-IM resource for interference measurement corresponds to interference and noise. In some examples, for resource allocation in the frequency domain for SBFD operation, NE 102 and / or UE 104 can consider misalignment boundaries between RBG and / or reporting subbands and SBFD subbands. For example, NE 102 and / or UE 104 can consider RBG, CSI reporting configuration, CSI-RS resource configuration, and / or PRB groups (PRG) for PDSCH resource allocation type 0. For semi-static SBFD, for CSI reporting subbands overlapping with SBFD subband boundaries, CSI reports are derived based on CSI-RS resources excluding CSI-RS resources used for downlink subbands of UE 104. For semi-static SBFD, CSI-RS resources overlapping with SBFD subband boundaries are valid for UE 104 within the downlink subband. In some examples, frequency resource allocation for CSI-RS across downlink subbands for UE 104 may include two consecutive CSI-RS resources linked together, one CSI-RS resource, a non-consecutive CSI-RS resource allocation, and / or a consecutive CSI-RS resource allocation having non-consecutive CSI-RS resources derived by excluding frequency resources outside the downlink subband.

[0099] For CSI reports associated with periodic or semi-persistent CSI-RS from a UE 104 aware of SBFD operation, if the periodicity causes the CSI-RS instance to appear in both SBFD and non-SBFD symbols in different time slots (e.g., each CSI-RS resource within a time slot has all SBFD or all non-SBFD symbols), the UE 104 can be configured with two CSI-ReportConfigs, one associated with an SBFD symbol and the other with a non-SBFD symbol. Non-SBFD symbols and / or non-SBFD time resources can be time resources not allocated for communication using the SBFD communication scheme. One CSI-ReportConfig can be associated with a CSI-RS limited to SBFD symbols, and a second CSI-ReportConfig can be associated with a second CSI-RS limited to non-SBFD symbols. Alternatively, both CSI-ReportConfigs can be associated with the same CSI-RS. A CSI report with one CSI-ReportConfig can be derived based on the CSI-RS instance in the SBFD symbol. A CSI report associated with a second CSI-ReportConfig can be derived based on a CSI-RS instance in a non-SBFD symbol. Alternatively, UE 104 can be configured with one CSI-ReportConfig associated with both SBFD and non-SBFD symbols. A CSI-ReportConfig can be associated with two CSI-RSs, limited to SBFD and non-SBFD symbols respectively. Individual CSI measurements are derived based on a first CSI-RS and a second CSI-RS respectively. A CSI-ReportConfig can be associated with one CSI-RS. CSI reports are derived based on CSI-RSs that may be in SBFD or non-SBFD symbols at different times. In some examples, whether CSI-RS resources are available for SBFD and non-SBFD symbols may depend on NE102 using the same and / or different antenna configurations in the two symbols.

[0100] According to the implementation scheme, one or more of NE 102 and UE 104 may be used to implement various aspects of the technology described with reference to this disclosure. For example, NE 102 (e.g., a base station) may transmit signaling to UE 104 indicating the allocation of one or more subbands within the CSI-RS frequency band for transmitting CSI-RS. NE 102 may transmit additional signaling to UE 104 to configure CSI reporting. For example, the additional signaling may indicate that the CSI report includes CSI-RS measurements, an indication of obtaining measurements by measuring SBFD time resources or non-SBFD time resources, an indication of a subset of subbands, and / or an indication of measurement error states. Alternatively or additionally, the additional signaling may indicate that the CSI report includes one or more measured CSI values, an error state including one or more monitoring times of CSI-RS, an indication of one or more frequency resources for the measured CSI values, and / or a measurement technique for obtaining CSI values. In some examples, NE 102 and / or another device may transmit one or more CSI-RS signals to UE 104 using the indicated sub-band within the CSI-RS band. UE 104 may, according to the relevant information... Figure 2 The standard selectively measures CSI-RS in a further detailed description and can transmit CSI reports to NE 102 based on additional signaling.

[0101] Figure 2 An example of a wireless communication system 200 according to aspects of this disclosure is shown. In some instances, the wireless communication system 200 implements aspects of the wireless communication system 100. For example, the wireless communication system 200 includes UE 104 and NE 102, which may be referenced. Figure 1 Examples of UE 104 and NE 102 are described. In some examples, NE 102 may wirelessly communicate with one or more other devices (e.g., UE 104) in the wireless communication system 200. For example, NE 102 may transmit and / or receive signaling from one or more UEs including UE 104. NE 102 may transmit signaling to UE 104 via downlink communication link 202. Alternatively, UE 104 may transmit signaling to NE 102 via uplink communication link 204. The signaling between NE 102 and UE 104 may include control signaling and / or data transmission.

[0102] In some cases, UE 104 may connect to NE 102 (e.g., a base station). For example, the base station may be a RAN node operating according to 4G, 5G and / or 6G RAN (e.g., TRP, Consumer Premises Equipment (CPE), Integrated Access and Backhaul (IAB) node, repeater, etc.).

[0103] NE 102 and / or UE 104 may implement one or more different communication schemes, including but not limited to TDD communication schemes and / or SBFD communication schemes. In the wireless communication system 100, TDD refers to a communication scheme that divides radio resources in the time domain between the downlink communication direction and the uplink communication direction. In a TDD communication scheme, at any point in time at a given frequency, NE 102 (e.g., a base station) transmits signals to one or more subscriber devices, or vice versa, as will be described in further detail with reference to Figure 3. In conventional cellular systems employing TDD, the TDD modes are synchronized and may be identical to avoid cross-link interference (CLI). In some examples, one or more devices in the wireless communication system 100 may additionally or alternatively implement a duplex communication scheme. For example, the devices may implement an SBFD communication scheme and / or SBFD operation, wherein one or more UEs 104 may be configured to transmit uplink signals in a subband using symbols allocated for downlink signaling, or vice versa, as will be described in further detail with reference to Figure 3. Figure 4 Further details are provided. Full-duplex capability on subbands is not expected for UE 104, but NE 102 may implement duplex enhancements for communication on subbands. In some examples, such as for SBFD operation at NE 102 within a TDD carrier, UE 104 may implement transmission, reception, and measurement behaviors and procedures in SBFD symbols and / or non-SBFD symbols. Alternatively or additionally, NE 102 may allocate communication resources in the frequency domain within SBFD symbols, including resource allocation in the frequency domain for PDSCH and / or CSI-RS across two downlink subbands in an SBFD symbol, resource allocation for misaligned boundaries between SBFD subbands and resource block groups (RBGs), resource allocation for CSI reporting subbands, resource allocation for one or more CSI-RS resources, and / or resource allocation for PRGs.

[0104] In some examples, UE 104 and / or NE 102 may determine one or more CSI-RS frequency resources where uplink subbands for semi-static and dynamic SBFD operation are available. For example, UE 104 may be configured with SBFD resource configuration. Using SBFD, subbands within the bandwidth of the radio link are configured to perform communication in a direction different from the communication direction in the remainder of the bandwidth. For example, an uplink subband on a downlink symbol refers to a subband within the downlink bandwidth that is available for uplink communication.

[0105] In some examples, NE 102, another base station, and / or RAN node configure CSI-RS for UE 104 for channel state measurements, interference measurements, beam management, etc. For example, NE 102 may transmit CSI-RS configuration signaling 206 to UE 104 via downlink communication link 202. In some examples, CSI-RS configuration signaling 206 may include explicit indications of one or more frequency resources used for measuring CSI-RS 208 in the CSI-RS band. For example, UE 104 may determine, based on signaling from RRC and / or L1 or L2, whether to include or exclude frequency resources (e.g., subbands, PRBs, RBGs) used to perform measurements on CSI-RS 208. This method may be referred to as explicit signaling. CSI-RS configuration signaling 206 may include parameters indicating a list of subbands to include and / or exclude. Subbands may comprise a subset of the frequency bands used for communication. Subbands can be configured or indicated as one or more PRBs in the air interface based on OFDM and / or Orthogonal Frequency Division Multiple Access (OFDMA). Entries in the list (e.g., parameters) can have corresponding indexes or IDs. The indexes can then be used for other communications, such as other configurations and / or L1 or L2 signaling. If UE 104 operates with dynamic SBFD, L1 and / or L2 signaling can be used to indicate subband indices to be included and / or excluded so that UE 104 can perform measurements on CSI-RS 208. In response, at 210, UE 104 can perform one or more measurements on subbands within the CSI-RS band. For example, by including and / or excluding the indicated subbands, UE 104 can perform one or more measurements on CSI-RS. UE 104 can then report the results of the measurements as configured by CSI reporting or beam reporting configuration. For example, NE 102 can transmit CSI report configuration signaling 212. CSI report configuration signaling 212 can instruct UE 104 to include one or more parameters in CSI report 214.

[0106] In some examples, a subband can be configured or indicated as one or more PRBs or RBGs. Subbands can be configured by RRC and / or indicated by L1 and / or L2 signaling. For example, a subband can be configured by two parameters such as {Start-RB, Number-of-RBs}, {Start-RB, End-RB}, etc. Alternatively or additionally, PRBs in the communication bandwidth (e.g., frequency band, carrier, CC, BWP) can be divided into groups of N consecutive RBs, where N is an integer pre-configured, defined, or indicated by the network. Example values ​​for N include, but are not limited to, 1, 2, 4, etc. If the bandwidth is... If there are N PRBs, this method divides the bandwidth into M groups of N consecutive PRBs, where Then, if a group of N consecutive RBs is called an RBG, the subband can be indicated by {Start-RBG, Number-of-RBGs}, {Start-RBG, End-RBG}, or by a bitmap of length M, where each bit can indicate whether the associated RBG is included (e.g., if bit = '1') or not included (e.g., if bit = '0'). It should be noted that if the number of PRBs... If the value is not an integer multiple of N, then the first RBG and / or the last RBG may contain a PRB with a value smaller than N. Whether this applies to the first RBG or the last RBG can be pre-configured, defined, or indicated by the network.

[0107] In some examples, CSI-RS configuration signaling 206 may include information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information, which pertains to... Figures 5 to 11 Further details are provided. Alternatively or concurrently, the CSI-RS configuration signaling 206 includes implicit indications of frequency resources used for CSI-RS measurements. For example, UE 104 may determine the CSI-RS frequency resources used for CSI measurements based on information not indicated by dedicated configuration or signaling. UE 104 may determine the CSI-RS frequency resources based on pre-configured or defined configurations, network configurations, UE implementation schemes, UE capability characteristics, etc.

[0108] In some examples, UE 104 may determine CSI-RS subbands based on one or more SBFD subbands. An SBFD subband may refer to a set of PRBs on which the communication direction differs from that outside the subband. For example, an uplink subband may refer to an uplink PRB on a downlink symbol, which is a symbol configured as downlink or configured flexibly and indicated and / or determined as downlink. Similarly, a downlink subband may refer to downlink PRBs on an uplink symbol, which is a symbol configured as uplink or configured flexibly and indicated and / or determined as downlink. In some cases, NE 102 configures a semi-static uplink subband for UE 104. NE 102 configures CSI-RS for UE 104, wherein the frequency resources indicated by the CSI-RS configuration may overlap with the uplink subband. In response, UE 104 can exclude uplink subband frequency resources (e.g., PRB, RBG) used for measurements on CSI-RS.

[0109] In some other cases, UE 104 may determine whether CSI-RS is on an SBFD symbol or a non-SBFD symbol. An SBFD symbol may refer to a downlink or flexible symbol on which UE 104 can transmit uplink signals within an uplink subband, or on which UE 104 can receive downlink signals within a downlink subband. If UE 104 determines that CSI-RS appears on an SBFD symbol, UE 104 may exclude the uplink subband and / or include the downlink subband on the symbol used for measurement. Alternatively, if UE 104 determines that CSI-RS does not appear on an SBFD symbol, UE 104 may determine the CSI-RS frequency resource based on other configurations or signaling, regardless of the SBFD subband configuration. In variations, CSI-RS measurement and CSI reporting are not limited to wideband or narrowband CSI-RS and may also be applied to cases where CSI-RS is configured for one or more defined subbands, where the subband differs from the SBFD subband on a particular symbol.

[0110] In some cases, if CSI-RS occupies multiple symbols, where at least one symbol is identified as an SBFD symbol and at least one symbol is identified as a non-SBFD symbol, UE 104 may treat CSI-RS as CSI-RS on SBFD symbols (e.g., excluding uplink subbands and / or including downlink subbands in CSI-RS frequency resources across multiple symbols), or treat CSI-RS as CSI-RS on SBFD symbols, provided that this behavior does not conflict with UE 104's other transmission and / or reception of a signal or channel. It may also treat CSI-RS as CSI-RS on non-SBFD symbols (e.g., not considering SBFD subbands when determining CSI-RS frequency resources across multiple symbols), or treat CSI-RS as CSI-RS on non-SBFD symbols, provided that this behavior does not conflict with UE 104's other transmission and / or reception of a signal or channel. In some examples, UE 104 may determine that the measurement on CSI-RS is an error condition and / or that the state of the CSI-RS measurement is an error state.

[0111] In some other examples, UE 104 may determine frequency resources based on guard band considerations. UE 104 may not perform measurements on resources (e.g., PRB, RBG, RE) that are not separated from the uplink subband by at least a minimum guard band (in kilohertz (kHz), PRB, RBG, etc.). If UE 104 determines to perform CSI-RS measurements on symbols using frequency resources that are not separated from the uplink subband by a minimum guard band, UE 104 may prioritize uplink subband (e.g., ignoring CSI-RS frequency resources (e.g., PRB, RBG, RE) that are not separated from the uplink subband by a minimum guard band), prioritize communication on the uplink subband (e.g., ignoring CSI-RS frequency resources that are not separated from uplink transmissions (e.g., PUSCH, PUCCH, SRS) on the uplink subband), and prioritize measurements (e.g., performing measurements on CSI-RS frequency resources that may affect any communication on the uplink subband). / or determine that the measurement of CSI-RS is an erroneous situation. In variations, the minimum guard band may be pre-configured, defined, configured by the network, indicated by L1 and / or L2 signaling, determined according to the implementation scheme or OAM settings, or any combination thereof. Any such method used to determine CSI-RS frequency resources may be used in combination with other methods, such as explicit signaling. In some cases, determining CSI-RS frequency resources based on explicit signaling (e.g., RRC, L1 and / or L2) and / or implicit determination is collectively referred to as subband inclusion and / or exclusion or similar terms.

[0112] In some examples, NE 102 may signal one or more configurations to UE 104 via downlink communication link 202 (e.g., signaling configuration to UE 104). Signaling and / or signaling may include RRC signaling, L1 and / or L2 messages, L1 and / or L2 indications, or L1 and / or L2 signaling, which are interchangeable and refer to lower-layer (i.e., Layer 1 and Layer 2) signaling. L1 control signaling may include one or more DCI messages signaled on, for example, the control channel of PDCCH. L2 control signaling may include Media Access Control-Control Element (MAC-CE) messages. Therefore, L1 and / or L2 signaling may refer to lower-layer control signaling and may include one or more DCI messages, one or more MAC-CE messages, etc. In some examples, higher-layer signaling, such as RRC, may be more reliable but may occur on a larger time scale. Conversely, lower-layer signaling, such as L1 and / or L2, is associated with smaller time scales and lower reliability. Therefore, for dynamic indication, L1 and / or L2 signaling may be more practical than the semi-static configuration of RRC, or may be used as a supplement to the semi-static configuration of RRC.

[0113] For dynamic SBFD, NE 102 can use a semi-static SBFD configuration with lower-layer signaling that dynamically indicates which subbands will be used by UE 104 for uplink or downlink communication. In some examples, the SBFD configuration and signaling provide uplink subbands on symbols configured or indicated as downlink symbols and / or provide downlink subbands on symbols configured or indicated as uplink symbols. In some cases, RRC configuration indicates which subbands to include and / or exclude when performing measurements on CSI-RS. For example, CSI-RS configuration signaling 206 may be RRC signaling and may indicate which subbands to include and / or exclude when performing measurements on CSI-RS. In response, UE 104 performs measurements on the indicated CSI-RS frequency resources in a semi-static manner.

[0114] Alternatively or concurrently, the CSI-RS configuration signaling 206 may be any other type of control signaling, including but not limited to DCI messages and / or MAC-CE. For example, L1 and / or L2 signaling in a DCI or MAC-CE message may indicate subbands to be included and / or excluded when performing measurements on the CSI-RS. In response, the UE 104 may perform CSI measurements on the CSI-RS frequency resources indicated by the L1 and / or L2 messages. In some cases, the UE 104 may determine the frequency resources by determining that the indication of including and / or excluding subbands overrides the associated indication from the RRC configuration and / or earlier L1 and / or L2 indications. In some other cases, the UE 104 may determine the frequency resources by determining that the indication of including subbands overrides the associated indication from the RRC configuration and / or earlier L1 and / or L2 indications. In still other cases, the UE 104 may determine the frequency resources by assuming that the indication of excluding subbands overrides the associated indication from the RRC configuration and / or earlier L1 and / or L2 indications.

[0115] In some examples, UE 104 may immediately apply subband inclusion and / or exclusion (e.g., for the next CSI measurement on the associated CSI-RS). Alternatively, UE 104 may apply timing for applying subband inclusion and / or exclusion. For example, UE 104 may perform and / or complete CSI measurements and reporting based on earlier configurations or L1 and / or L2 indications before applying the indicated subband inclusion and / or exclusion. For example, if a current or ongoing CSI measurement is to be performed during multiple measurement times, UE 104 may complete the CSI measurement before starting to apply the most recently indicated subband inclusion and / or exclusion to the next measurement.

[0116] In some other examples, UE 104 may apply timing for the duration or value of a configuration or defined value for a CSI measurement before switching back to subband inclusion and / or exclusion based on an earlier configuration or L1 and / or L2 indication. For example, UE 104 may receive dynamic L1 and / or L2 indications to fully or partially override an associated semi-static configuration. UE 104 may determine that the L1 and / or L2 indications are for the duration or value of a CSI measurement (e.g., aperiodic indications) and are indeterminate (e.g., semi-persistent indications). In some other examples, UE 104 may receive L1 indications and / or earlier L2 indications to override an associated semi-static configuration. UE 104 may determine that the L1 indications are for the duration or value of a CSI measurement (e.g., aperiodic), and then apply the semi-static configuration and / or L2 indications (e.g., semi-persistent).

[0117] In variations, one or more parameters can influence timing, such as the duration of application inclusion and / or exclusion, the magnitude of CSI measurements, the timing of CSI monitoring or the magnitude of CSI-RS resources, the start time of application inclusion and / or exclusion, the end time of application inclusion and / or exclusion, etc., which can be pre-configured or defined by the network, configured, indicated by L1 and / or L2 signaling, determined according to the implementation scheme or OAM settings, or any combination thereof. In some examples, in addition to or instead of configuring and / or L1 and / or L2 indications, UE 104 can determine subband inclusion and / or exclusion by applying one or more rules. For example, UE 104 may consider the minimum bandwidth (e.g., the magnitude of total PRB or RE) on which CSI measurements are performed, because measurements of small PRB or RE values ​​may be inaccurate. However, since UE 104 may consider multiple subband indications, such as from RRC or lower layers, these indications can collectively result in a lower value of PRB or RE below the minimum. In some cases, UE 104 may ignore, disregard, or discard one or more of the indications. For example, UE 104 may ignore or disregard the most recent L1 and / or L2 indication. In some other examples, UE 104 may ignore or discard the earliest associated L1 and / or L2 indication that is still valid. In still other examples, UE 104 may ignore or discard one or more L1 and / or L2 indications and consider the associated semi-static configuration, or vice versa. In still other examples, UE 104 may ignore or discard one or more L1 indications and consider the associated semi-static configuration and / or L2 indication, or vice versa.

[0118] In various implementations, UE 104 may prioritize semi-static configuration over L1 and / or L2 indications, or vice versa, and / or may prioritize L2 indications over L1 indications, or vice versa. In some examples, prioritizing a first indication over a second indication may include ignoring or discarding the first indication if considering it together with the second indication might jointly violate the minimum bandwidth used for measurement. For one or more CSI measurements, the first indication may be ignored, or discarded as long as the first indication results in a violation, or discarded from that point onwards. In some cases, the minimum guard band may be pre-configured or defined by the network, configured, indicated by L1 and / or L2 signaling, determined according to the implementation or OAM settings, or any combination thereof.

[0119] In some examples, UE 104 may be constrained to perform measurements on subbands due to constraints from other configurations, indications, scheduling, communications, etc. For example, if UE 104 is to perform measurements on PRBs or REs that do not have a minimum guard band separate from the uplink subband, UE 104 may be unable to perform measurements on the PRBs or REs. Constraints may be due to implementation schemes or configurations. UE 104 may apply rules for ignoring or discarding one or more indications (e.g., by RRC and / or L1 and / or L2). These rules may be similar to rules proposed for performing measurements on PRBs or REs with minimum numerical values. In variations, the minimum guard band may be pre-configured or defined by the network, configured, indicated by L1 and / or L2 signaling, determined according to the implementation scheme or OAM settings, or any combination thereof. If UE 104 needs to determine CSI-RS frequency resources based on conflicting explicit signaling and implicit determinations, UE 104 may prioritize explicit signaling per resource (e.g., when conflicting with implicit determinations, including or excluding CSI-RS resources in the measurement as indicated by explicit signaling, but following implicit determinations for resources that do not cause conflict), prioritize implicit determinations per resource (e.g., as implicitly determined, including or excluding CSI-RS resources in the measurement, but following explicit signaling for resources that do not cause conflict), ignore or discard implicit determinations (e.g., including or excluding CSI-RS resources in the measurement as indicated by explicit signaling, and discarding or ignoring implicit determinations for resources that may or may not cause conflict), ignore or discard explicit signaling (e.g., as implicitly determined, including or excluding CSI-RS resources in the measurement, and discarding or ignoring explicit signaling for resources that may or may not cause conflict), and / or determine that the measurement on CSI-RS 208 is an error condition. Examples of explicit signaling include indications via RRC or L1 and / or L2 signaling. Examples of implicit determination include determining CSI-RS subbands based on SBFD subbands, applying minimum bandwidth, and applying or minimum guard bands. UE 104 may follow rules that prioritize a set of methods for determining CSI-RS frequency resources used for measurement, each of which may include explicit signaling, implicit determination, or both. These rules may be pre-configured or defined by the network, configured, indicated by L1 and / or L2 signaling, determined according to the implementation scheme or OAM settings, or any combination thereof.

[0120] In some examples, the measurement may include error conditions and / or have an error state. Error conditions may occur for various reasons, including but not limited to UE 104 receiving a conflict indication from one or more serving NEs, UE 104 losing control signaling from NE 102 (e.g., due to an error in receiving a DCI message), and / or UE 104 detecting a conflict between the indication from serving NE 102 and UE 104's capabilities (e.g., minimum guard band). Error conditions may be accepted as normal or common behavior of UE 104 to reduce system complexity. When it is determined that a measurement on CSI-RS 208 is an error condition, UE 104 may determine whether to perform an action and / or not to perform an action. For example, UE 104 may ignore the measurement and not send the associated CSI report 214, may ignore the measurement and send the associated CSI report 214 containing an indication of the error condition (e.g., a parameter with a NULL value, a CQI=0 value, an out-of-bounds value, an indication of the error condition type), may perform the measurement with best efforts (e.g., based on explicit signaling and / or implicit indications, including as many frequency resources as possible for CSI-RS 208 while excluding conflicting frequency resources; and then send the associated CSI report 214 containing the measurement results), and / or may perform the measurement with best efforts and send the associated CSI report 214 containing the measurement results and an indication of the error condition.

[0121] In some examples, CSI report 214 can be enhanced to include information about the CSI-RS frequency resources on which UE 104 has performed measurements to obtain CSI values. This approach can be used in scenarios where NE 102 may have ambiguity regarding the frequency resources of the CSI-RS measured by UE 104 to generate CSI report 214. Furthermore, CSI report 214 with this format is self-contained because it indicates the frequency resources associated with the CSI values. Therefore, this enhanced CSI report format reduces the complexity of NE 102 for link adaptation and scheduling when frequency resources monitored by UE 104 change dynamically, which can be particularly useful when employing dynamic SBFD.

[0122] In some examples, UE 104 may send a CSI report 214 containing one or more CSI values ​​(e.g., measured at 210) and an indication of whether the CSI values ​​were obtained through measurements of SBFD symbols or non-SBFD symbols. The indication may be bits for each or more CSI values. CSI report 214 may contain multiple such indications, each associated with one or more CSI values. In some other examples, UE 104 may send a CSI report 214 containing one or more CSI values ​​and an indication of subband or frequency resources included and / or excluded for the measurement to obtain the CSI values. The indication may include an ID and / or index indicated by the configuration of the subband or frequency resource (e.g., an ID and / or index associated with a subband indicated by parameters freqBand, freqBand2, freqBandSet, freqBandSets, etc.), an ID and / or index indicated by L1 and / or L2 signaling of the subband or frequency resource, a value of N (e.g., the numerical amount of PRBs in the RBG and / or subband), a value of M (e.g., the numerical amount of RBG and / or subbands included and / or excluded for measurement), a value between 1 and K (e.g., the numerical amount of subband included and / or excluded combinations), or equivalently a value between 0 and K-1 indicating which of the K subband included and / or excluded combinations will be applied to the measurement to obtain a CSI value, and / or a bitmap indicating the subband included and / or excluded combinations applied to the measurement to obtain a CSI value.

[0123] In some other examples, UE 104 may send a CSI report 214 containing one or more CSI values ​​and an indication of an error condition that occurred when the measurement was performed to obtain the CSI value. Examples of error conditions include methods for determining conflicts in the CSI-RS frequency resources used for the measurement. In some implementations, one or more of the CSI values ​​may indicate an error condition (e.g., null value, CQI=0 value, out-of-bounds value). The behavior of UE 104 according to any of the examples and implementations may be pre-configured or defined by the network, configured, indicated by L1 and / or L2 signaling, determined according to the implementation scheme or OAM settings, or any combination thereof.

[0124] CSI values ​​can be obtained by combining the results of multiple measurements, each performed at a measurement timing. These multiple measurement timings can be associated with the same reference signal, such as CSI-RS 208. For example, to obtain a wideband CSI value, UE 104 can perform multiple measurements on CSI-RS 208 using the same wideband frequency resources on multiple symbols. Similarly, to obtain a narrowband CSI value, UE 104 can perform multiple measurements on CSI-RS 208 using the same narrowband frequency resources on multiple symbols, as indicated by the CSI-RS resource configuration. In variations, UE 104 can determine different combinations of subbands or frequency resources associated with the same CSI-RS 208. If a CSI value is obtained based on a single measurement or based on multiple measurements of the same and / or consistent frequency resources, the CSI value can be reported according to an enhanced CSI reporting format that includes an indication of the subband configuration associated with the CSI value. However, if the CSI value is obtained based on multiple measurements using different and / or inconsistent frequency resources, the UE 104 can combine the results of the measurements.

[0125] In some examples, if UE 104 obtains multiple CSI values ​​based on different and / or inconsistent frequency resources, UE 104 may report the CSI values ​​separately, such that CSI values ​​with the same and / or consistent frequency resources are combined. In some other examples, UE 104 may ignore one or more measurements among those to be performed on different and / or inconsistent resources. UE 104 may ignore the first measurement, the last measurement, the minority of all measurements, the measurement associated with the lowest total bandwidth, the measurement associated with the highest total bandwidth, etc. In some other examples, UE 104 may combine measurement results on the union of frequency resources (e.g., on PRB, RBG, or subbands common to all or some frequency resources determined for multiple monitoring times). The union may be referred to as bandwidth overlap between monitoring times. In some other examples, UE 104 may combine measurement results as best as possible or according to the implementation scheme.

[0126] In some cases, in addition to or in lieu of one or more CSI values, CSI report 214 may include indications of error conditions associated with different and / or inconsistent frequency resources used for multiple monitoring times, indications of one or more associated frequency resources (e.g., subband and / or RBG inclusion and / or exclusion combinations) among the CSI values ​​in the report, and / or indications of methods for resolving inconsistencies in frequency resources used for multiple monitoring times. The behavior of UE 104, according to any of the examples and implementations, may be pre-configured or defined by the network, configured, indicated by L1 and / or L2 signaling, determined according to the implementation scheme or OAM settings, or any combination thereof. In some examples, to implement the SBFD scheme, NE 102 may employ analog and / or digital technologies to achieve full-duplex operation on SBFD subbands. Therefore, the antenna panel and configuration for communication on SBFD symbols may differ from those for communication on non-SBFD symbols, resulting in significant differences in CSI values ​​(e.g., including beam index values) between the two types of symbols, which will affect the accuracy of the information provided. Figure 12 and 13 Further detailed description.

[0127] In some examples, NE 102 may instruct UE 104 to perform various frequency resource-based configurations for measuring and reporting CSI without exhausting the quota of the CSI-RS resource configuration. This increases the complexity of CSI measurement and reporting at UE 104. Since different UE 104s may have varying capabilities to handle this complexity, new UE 104 capability features may be introduced for use in UE 104 capability features that signal to the network. UE 104 may not expect to perform actions beyond those it instructs the network via signaling. For example, UE 104 may indicate one or more capabilities in capability signaling 216. UE 104 may include capability signaling 216 in existing or new control messages (e.g., RRC signaling, MAC-CE, and / or DCI messages). In some examples, capability signaling 216 may include one or more parameters, such as the maximum value of a subband configured by RRC and / or indicated by L1 and / or L2 signaling, the maximum value of a combination of subbands activated and / or indicated in a single instance, the maximum value of a combination of subbands activated and / or indicated during a specific time period of T time slots and / or symbols, the maximum value of subband combination variation during a specific time period of T time slots and / or symbols, the minimum bandwidth (e.g., in kHz, PRB, RBG) for valid measurements of each consecutive subband or for the sum of discontinuous subbands, the maximum value of a subband per measurement, the maximum value of a subband indication to be included in CSI report 214, the maximum value of a combination of subbands used for CSI values ​​based on multiple monitoring opportunities, and / or the maximum value of an antenna panel or configuration (e.g., the maximum value for the value of AntennaConfig). In some cases, the minimum or maximum value of each of the UE capability characteristics may be pre-configured or defined.

[0128] Figure 3 illustrates an example of a resource diagram 300 according to aspects of this disclosure. In some examples, resource diagram 300 implements aspects of wireless communication system 100 and / or wireless communication system 200. For example, resource diagram 300 may be implemented by a UE and / or NE, and may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Resource diagram 300 may illustrate an example of resource allocation for a TDD communication scheme.

[0129] In some examples, the NE can transmit signaling that schedules one or more time-frequency resources for transmissions to or from the UE. For example, the NE can schedule control signaling transmissions and / or data transmissions to or from the UE. Time-frequency resources may comprise one or more resources in the time domain (e.g., time slots). A time slot may be a communication resource element in the time domain and may be further divided into one or more smaller units called symbols. In variations, time resource 302 may be an example of a time slot and / or a symbol. In some cases, the corresponding time resource 302 may be allocated for uplink signaling and may be referred to as an uplink resource. In some other cases, the corresponding time resource 302 may be allocated for downlink signaling and may be referred to as a downlink resource.

[0130] In some examples, the NE may indicate a periodicity 304 on which a pattern of repeating uplink and downlink resources is applied. For example, periodicity 304 may be any numerical amount of time slots and / or symbols on which a pattern of repeating uplink and downlink resources is applied. Although Figure 3 shows a periodicity 304 of six time resources 302, periodicity 304 may be any numerical amount of time resource 302. Alternatively or additionally, the pattern may contain any numerical amount of uplink and / or downlink resources. During uplink resource periods, the UE may transmit signaling to the NE, and during downlink resource periods, the UE may receive signaling from the NE. For TDD communication schemes, time resource 302 may be allocated to either uplink or downlink resources, but not both.

[0131] Figure 4 An example of resource diagram 400 according to aspects of this disclosure is shown. In some examples, resource diagram 400 implements aspects of wireless communication system 100, wireless communication system 200, and / or resource diagram 300. For example, resource diagram 400 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Resource diagram 400 may illustrate an example of resource allocation for the SBFD communication scheme.

[0132] In some examples, the NE can transmit signaling that schedules one or more time-frequency resources for transmissions to or from the UE. For example, the NE can schedule control signaling transmissions and / or data transmissions to or from the UE. Time-frequency resources may comprise one or more resources in the time domain (e.g., time slots and / or one or more symbols). In variations, time resource 402 may be an example of a time slot and / or a symbol. In some cases, the corresponding time resource 402 may be allocated for uplink signaling and may be referred to as an uplink resource. In some other cases, the corresponding time resource 402 may be allocated for downlink signaling and may be referred to as a downlink resource. In still other cases, the corresponding time resource 402 may be divided into uplink and downlink resources across frequency resources. For example, different sub-bands within a frequency band may be allocated for uplink and downlink transmissions, such that uplink and downlink transmissions occur simultaneously or concurrently in time resource 402.

[0133] Uplink subband 404 can divide bandwidth into one or more subbands. For example, uplink subband 404 can be divided into two or three subbands, with one uplink subband 404 adjacent to one or more downlink subbands 406. Bandwidth can be configured for downlink (e.g., via TDD configuration, as described with reference to Figure 3), and then the uplink subbands can be partitioned (e.g., indicated by SBFD subband configuration). However, the remaining downlink resources are also referred to as subbands. For example, uplink subband 404 can be configured within the downlink bandwidth, two downlink subbands 406 and uplink subband 404 can be configured individually, and / or two downlink subbands 406 can be configured within the uplink bandwidth.

[0134] Uplink subband 404 and downlink subband 406 may be separated by frequency resources representing the gap between uplink subband 404 and downlink subband 406 (referred to as guard band 408). In some examples, guard band 408 may be explicitly configured or implicitly determined between two adjacent subbands, particularly between adjacent subbands in different directions (e.g., between downlink subband 406 and uplink subband 404). Guard band 408 may be configured or determined as a numerical value of PRB on which the UE is expected to neither transmit nor receive signals. In some examples, the wireless communication system may be inherently half-duplex (e.g., the transceiver may transmit or receive once through the same antenna, but not simultaneously). However, using advanced duplex schemes (e.g., SBFD), either or both of the NE and UE may employ advanced duplex schemes to communicate simultaneously in both the downlink and uplink.

[0135] In this variant, the UE can receive signals (e.g., CSI-RS) on a portion of the bandwidth (e.g., one or more downlink subbands 406) while blocking the use and / or monitoring of the remaining portion of the bandwidth. This contrasts with configurations of CSI-RS or other reference signals that are configured to be wideband (e.g., occupying the entire bandwidth) or narrowband within semi-static and / or static continuous subbands.

[0136] In some examples, the NE may indicate a periodicity 410 of a pattern on which uplink and downlink resources are applied. For example, periodicity 410 may be any numerical amount of time slots and / or symbols on which uplink and downlink resources are applied. For SBFD, the pattern may change and / or may be consistent over a duration. That is, the pattern may be periodic, non-periodic, and / or dynamically updated. Although Figure 3 shows a periodicity 410 of six time resources 402 with a non-repeating pattern, periodicity 410 may be any numerical amount of time resources 402 and / or repeatable. Alternatively or additionally, the pattern may contain any numerical amount of uplink and / or downlink resources. During uplink resource periods, the UE may transmit signaling to the NE, and during downlink resource periods, the UE may receive signaling from the NE.

[0137] Figure 5 An example of a configuration diagram 500 according to aspects of this disclosure is shown. In some examples, configuration diagram 500 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, and / or resource diagram 400. For example, configuration diagram 500 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Configuration Figure 500 shows an example of an explicit configuration of CSI-RS.

[0138] In some examples, the NE may send CSI-RS configuration signaling to the UE, which may contain information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. For example, the NE may send CSI-RS configuration signaling to the UE by sending information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. Figure 5 The information element format shown is used to configure the UE with CSI reports and associated CSI-RS resources. For example, the information element may use one or more parameters (e.g., freqBand, freqBand2, etc.) defined within the information element to indicate one or more frequency bands. In response, if the UE receives the optional parameter freqBand2, the UE performs measurements on the CSI-RS resources indicated by both freqBand and freqBand2. Although two frequency band parameters are shown, the information element format can contain frequency band parameters of any numerical value.

[0139] Figure 6An example of a configuration diagram 600 according to aspects of this disclosure is shown. In some examples, configuration diagram 600 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, and / or configuration diagram 500. For example, configuration diagram 600 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Configuration Figure 600 shows an example of an explicit configuration of CSI-RS.

[0140] In some examples, the NE may send CSI-RS configuration signaling to the UE, which may contain information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. For example, the NE may send CSI-RS configuration signaling to the UE by sending information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. Figure 6 The IE (which may be referred to as a CSI-RS resource mapping information element) in the shown format is used to configure the UE with CSI reports and associated CSI-RS resources. For example, the information element may indicate a set of frequency bands (e.g., freqBandSet) having one or more parameters defining the set of frequency bands. The parameters may include the size of the set (e.g., SIZE(1…maxNrofCSI-FrequencyOccupation)). In response, if the UE receives the optional parameter freqBandSet, the UE may ignore the parameter freqBand and perform measurements on the CSI-RS resources indicated by the sub-band set indicated by freqBandSet.

[0141] Alternatively, the NE may transmit L1 and / or L2 messages to the UE indicating a subset of subbands configured by the parameter freqBandSet. The indication may be a bitmap, where M bits are associated with the M subbands indicated by the parameter freqBandSet. The bitmap may have a length M, or alternatively, the bitmap may be longer, in which case the UE may consider the first M bits or the last M bits and ignore (e.g., disregard) the remaining bits. The parameter maxNrofCSI-FrequencyOccupation indicates the maximum value of M. In response, for a corresponding subband in the set of M subbands, if the associated bit in the bitmap takes a first value (e.g., '1'), the UE includes the CSI-RS resources limited to the subband, and if the associated bit in the bitmap takes a second value (e.g., '0'), the UE excludes the subband.

[0142] Figure 7 An example of a configuration diagram 700 according to aspects of this disclosure is shown. In some examples, configuration diagram 700 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, and / or configuration diagram 600. For example, configuration diagram 700 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Configuration Figure 700 shows an example of an explicit configuration of CSI-RS.

[0143] In some examples, the NE may send CSI-RS configuration signaling to the UE, which may contain information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. For example, the NE may send CSI-RS configuration signaling to the UE by sending information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. Figure 7 The configuration information in the format shown is used to configure the UE using CSI reports and associated CSI-RS resources. For example, the configuration information may indicate the numerical value of the RBs per subband as a parameter in the configuration information (e.g., nrofRBsPerSubband). That is, the NE can configure the UE with a configuration containing the parameter freqBand and the integer parameter nrofRBsPerSubband, the integer parameter indicating the numerical value of N = the PRBs per subband. Alternatively or additionally, the NE transmits L1 and / or L2 messages to the UE indicating a subset of subbands, where the corresponding subband has a bandwidth of N PRBs. The indication may be a bitmap, where M bits are associated with M subbands. The maximum value of the subband numerical value can be pre-configured, defined, and / or obtained by dividing nrofRB (e.g., in freqBand) by N (e.g., indicated by nrofRBsPerSubband). In response, for a given subband in a set of M subbands, if the associated bit in the bitmap is a first value (e.g., '1'), the UE includes the CSI-RS resources confined to the subband, and if the associated bit in the bitmap is a second value (e.g., '0'), the UE excludes the subband.

[0144] Figure 8 An example of resource diagram 800 according to aspects of this disclosure is shown. In some examples, configuration diagram 800 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, configuration diagram 600, and / or configuration diagram 700. For example, resource diagram 800 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Resource Figure 800 may illustrate an example of indexing techniques for subbands used in CSI-RS.

[0145] In some examples, the BWP, CC, and / or frequency band may include a CSI-RS frequency band. The CSI-RS frequency band may include one or more frequency resources on which CSI-RS can be transmitted. In some cases, the BWP, CC, and / or frequency band may be divided into one or more sub-bands (e.g., M sub-bands), including sub-band 0, sub-band 1, and / or sub-band M-1. In variations, the UE may determine that the first sub-band includes the first N PRBs in the frequency band configuration (e.g., from...). Figures 5 to 7 The second subband (freqBand) contains the second Nth PRB in the frequency band configuration, etc. For this purpose, the UE numbers or indexes the PRBs starting from the PRB indicated by the startingRB parameter.

[0146] Figure 9 An example of resource diagram 900 according to aspects of this disclosure is shown. In some examples, resource diagram 900 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, configuration diagram 600, configuration diagram 700, and / or resource diagram 800. For example, resource diagram 900 may be implemented by UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Resource Figure 900 may illustrate an example of indexing techniques for subbands used in CSI-RS.

[0147] In some examples, the BWP, CC, and / or frequency band may include a CSI-RS frequency band. The CSI-RS frequency band may include one or more frequency resources on which CSI-RS can be transmitted. In some cases, the BWP, CC, and / or frequency band may be divided into one or more sub-bands (e.g., M sub-bands), including sub-band 0, sub-band 1, sub-band 2, and / or sub-band M-1. In a variant, the UE may determine the sub-band boundary with respect to a first PRB in the frequency band, carrier, CC, BWP, etc. The first sub-band associated with the first bit in the bitmap is then determined to be the sub-band containing the PRB indicated by the indicated start RB (e.g., by the parameter startingRB), and the second sub-band associated with the second bit is determined to be the sub-band following the first sub-band, and so on.

[0148] Figure 10 An example of a configuration diagram 1000 according to aspects of this disclosure is shown. In some examples, configuration diagram 1000 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, configuration diagram 600, configuration diagram 700, resource diagram 800, and / or resource diagram 900. For example, configuration diagram 1000 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Configuration Figure 1000 shows an example of an explicit configuration of CSI-RS.

[0149] In some examples, the NE may send CSI-RS configuration signaling to the UE, which may contain information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. For example, the NE may send CSI-RS configuration signaling to the UE by sending information elements indicating one or more subbands for measuring CSI-RS and / or other configuration information. Figure 10The configuration information in the format shown is used to configure the UE using CSI reports and associated CSI-RS resources. For example, the configuration information may indicate one or more parameters that indicate the set of frequency bands in the resource mapping information element. The NE may configure the UE with the parameter nrofRBsPerSub-band via another configuration information element, or indicate the values ​​of N PRBs for each sub-band and / or RBG to the UE via L1 and / or L2 messages.

[0150] In some cases, when it is determined that CSI-RS resources are used to measure the PRB of CSI, the NE configures or indicates the sets of subbands to be included and / or excluded. By extension, the NE can configure or indicate multiple sets of subbands, where the corresponding sets are associated with CSI reports or CSI values ​​in CSI reports (e.g., for a first CSI value obtained by measuring a first set of subbands that differs from a second CSI value obtained by measuring a second set of subbands). The reason for the measurement difference is the frequency selectivity of the radio channel. Alternatively or additionally, in the case of SBFD, the difference may be caused by different antenna configurations used by the NE to transmit CSI-RS on the subbands. Therefore, the NE can determine the CSI values ​​obtained by measuring CSI-RS in different combinations of subbands, allowing the NE to determine which subbands to configure or indicate for SBFD operation. This method is applicable not only to dynamic SBFD where the NE can dynamically indicate different subbands for SBFD, but also to semi-static SBFD where the NE can change the SBFD subband configuration.

[0151] In some cases, NE is used Figure 10The CSI-RS-ResourceMapping information element shown is used to configure the UE. The UE can determine the optional parameter freqBandSets, indicating a set of K parameters of type freqBandSet. The corresponding parameters of type freqBandSet indicate a set and / or list of M subbands, where each of the M subbands (e.g., each subband) contains N PRBs indicated by startingRB and nrofRBs. In some cases, the value of N may be different in each subband because the values ​​of startingRB and nrofRBs may be different for different subbands. Similarly, the value of M may be different in each of the K subband sets. The UE can use a first subband set of the K subband sets to determine the frequency resources (e.g., PRBs) for CSI-RS to measure and obtain a first CSI value, use a second subband set to determine the frequency resources (e.g., PRBs) for CSI-RS to measure and obtain a second CSI value, and so on. The UE can then send one or more CSI reports to the NE, where each CSI report may contain one or more CSI values. Although this example can be implemented via multiple CSI-RS resource configurations (e.g., K configurations), the advantage of implementing it via a set of K subbands indicated by a single CSI-RS resource configuration or associated with a single CSI-RS resource configuration is reduced complexity, as the UE maintains a smaller number of configurations for the same task.

[0152] Figure 11 An example of resource diagram 1100 according to aspects of this disclosure is shown. In some examples, resource diagram 1100 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, configuration diagram 600, configuration diagram 700, resource diagram 800, resource diagram 900, and / or configuration diagram 1000. For example, resource diagram 1100 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Resource diagram 1100 may show an example of CSI-RS frequency resource allocation.

[0153] In some examples, the BWP, CC, and / or band may include a CSI-RS band. The CSI-RS band 1102 may contain one or more frequency resources on which CSI-RS can be transmitted. In some cases, the CSI-RS band 1102 may contain one or more sub-bands, PRBs, or other frequency resources. The NE may transmit CSI-RS according to a periodicity, such as CSI-RS periodicity 1104. For example, the NE may use one or more downlink resources in the CSI-RS band 1102 to transmit CSI-RS, the CSI-RS band including uplink and downlink resources. In some cases, the UE may determine the CSI-RS frequency resources each time a CSI-RS occurs within the configured CSI-RS band 1102. The occurrence of CSI-RS frequencies is separated in the time domain by CSI-RS periodicity 1104. Each CSI-RS periodicity 1104 may be associated with a measurement timing.

[0154] Figure 12 An example of configuration diagram 1200 according to aspects of this disclosure is shown. In some examples, configuration diagram 1200 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, configuration diagram 600, configuration diagram 700, resource diagram 800, resource diagram 900, configuration diagram 1000, and / or resource diagram 1100. For example, configuration diagram 1200 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Configuration Figure 1200 may show an example of antenna configuration for SBFD subband configuration.

[0155] In some examples, when operating using SBFD communication technology, the NE can use different antenna panels to transmit signaling. For example, to implement an SBFD scheme, the NE may employ analog and / or digital technologies that enable full-duplex operation on SBFD subbands. Therefore, the antenna panels and configurations used for communication on SBFD symbols may differ from those used for communication on non-SBFD symbols, potentially resulting in different CSI values ​​(e.g., including beam index values) between the two types of symbols. By extension, different SBFD subbands or subband combinations can be implemented through different antenna panels and configurations at the NE. The NE can then assume that the channel state associated with each of the antenna panels and configurations is different, and therefore may not combine measurements obtained from different antenna panels and configurations. Therefore, if the UE is able and / or configured to combine measurement results for dissimilar and / or inconsistent frequency resources, the NE can transmit signaling indicating combinations that produce valid and / or meaningful results and combinations that do not produce valid and / or meaningful results.

[0156] In a variant, the UE may receive one or more parameters referred to as AntennaConfig, each of which is associated with a subband and / or RBG combination (e.g., subband and / or RBG inclusion and / or exclusion combinations). The value of the AntennaConfig parameter may have a one-to-one association with an antenna panel or configuration (e.g., a first value for the parameter may indicate a first antenna panel or configuration, a second value may indicate a second antenna panel or configuration, etc.). In response, the UE may determine that it can combine measurements of subband and / or RBG combinations associated with the same value of the AntennaConfig parameter. In some examples, the parameter may be indicated via configuration or L1 and / or L2 signaling from the NE. Figure 12 The diagram illustrates an example instruction for configuration via RRC. For instance, the configuration may include an antennaConfig parameter, which indicates the maximum number of antenna configurations for the set of frequency bands to be configured (e.g., maxNrofAntennaConfig).

[0157] Figure 13 An example of configuration diagram 1300 according to aspects of this disclosure is shown. In some examples, configuration diagram 1300 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, configuration diagram 600, configuration diagram 700, resource diagram 800, resource diagram 900, configuration diagram 1000, resource diagram 1100, and / or configuration diagram 1200. For example, configuration diagram 1300 may be implemented by a UE and / or NE, which may be used as a reference. Figure 1 Examples of UE 104 and / or NE 102 are described. Configuration Figure 1300 may show an example of antenna configuration for SBFD subband configuration.

[0158] In some examples, when operating using SBFD communication technology, the NE can use different antenna panels to transmit signaling, as shown in the reference. Figure 12 As described. The UE may receive one or more parameters called AntennaConfig, each of which is associated with a subband and / or RBG combination (e.g., subband and / or RBG inclusion and / or exclusion combination). Figure 13 The diagram illustrates an example instruction for configuration via RRC. For instance, the configuration may include an antennaConfig parameter, which indicates the maximum number of antenna configurations for one or more frequency band sets (e.g., maxNrofAntennaConfig).

[0159] In the variant, it is assumed that the parameter AntennaConfig takes an integer value between 1 and the maximum numerical value of the antenna configuration. Other parameter types are not excluded. Similarly, the parameter may be indicated by L1 and / or L2 signaling, for example, associated with another indication of bitmap or subband inclusion and / or exclusion combinations. For example, the UE may receive a CSI report configuration indicating CSI-RS resource configuration. The UE receives an indication of a first value associated with a first frequency resource set for CSI-RS and AntennaConfig. Alternatively, the UE receives an indication of a second value associated with a second frequency resource set and AntennaConfig. The UE performs a first measurement on the first CSI-RS frequency resource set to obtain a first CSI value, and performs a second measurement on the second CSI-RS frequency resource set to obtain a second CSI value. The UE compares the first value of AntennaConfig with the second value of AntennaConfig. If the values ​​are the same (e.g., equal), the UE may determine that it can combine the first CSI value and the second CSI value. If the AntennaConfig values ​​are not the same, the UE may determine that it will not combine the CSI values.

[0160] Figure 14 An example of signaling diagram 1400 according to aspects of this disclosure is shown. In some examples, signaling diagram 1400 implements aspects of wireless communication system 100, wireless communication system 200, resource diagram 300, resource diagram 400, configuration diagram 500, configuration diagram 600, configuration diagram 700, resource diagram 800, resource diagram 900, configuration diagram 1000, resource diagram 1100, configuration diagram 1200 and / or configuration diagram 1300. Signaling diagram 1400 may show an example of configuring CSI-RS resources for SBFD operation at NE 102 and / or UE 104. NE 102 and UE 104 may be as referenced Figures 1 to 13 Examples of UE 104 and NE 102 are described. Alternative examples of the following may be implemented, some of which may be performed in a different order than described, or not at all. In some cases, procedures may include additional features not mentioned below, or additional procedures may be added.

[0161] In some examples, at 1402, UE 104 may transmit capability signaling to NE 102. Capability signaling may contain one or more parameters or other information indicating the capabilities of UE 104 related to CSI-RS resource allocation for SBFD operation. UE 104 may transmit capability signaling in control signaling (e.g., uplink control information (UCI) and / or another message and / or control signaling). UE 104 may send capability signaling in a message dedicated to indicating the capabilities of UE 104 related to CSI-RS resource allocation for SBFD operation and / or in another capability message that additionally or alternatively indicates other capability information related to UE 104. Capability signaling may include at least one of the following: the maximum value of a subband supported by UE 104, the maximum value of a subband combination, the maximum value of a subband combination associated with a time period, the maximum value of a subband combination change associated with a time period, the minimum bandwidth for at least one measurement as a valid measurement, the maximum value of a subband for a corresponding measurement in at least one measurement, the maximum value of a subband indication included in a CSI report, the maximum value of a combination of CSI values ​​based on multiple monitoring times, or the maximum value of an antenna panel supported by UE 104.

[0162] At 1404, UE 104 can receive signaling configuring CSI-RS transmission. For example, the signaling may indicate a set of sub-bands within the CSI-RS band. The signaling may be an example of control signaling (e.g., RRC signaling, MAC-CE, DCI messages). The signaling may contain one or more parameters (e.g., information elements or other control information) indicating the set of sub-bands within the CSI-RS band. In variations, the corresponding sub-bands in the sub-band set contain PRBs and / or RBGs.

[0163] In some instances, the signaling configuring CSI-RS transmission includes one or more parameters indicating the corresponding indexes of sub-bands within the CSI-RS band. These parameters may include information elements indicating the corresponding index, information elements indicating one or more sets of indexes of the sub-band set within the CSI-RS band, a bitmap indicating the corresponding index, and / or parameters indicating the numerical value of the PRB for each sub-band in the sub-band set within the CSI-RS band. In some cases, the signaling configuring CSI-RS transmission is used for semi-static frequency resource allocation for uplink sub-bands and for frequency resource allocation for the CSI-RS band, the frequency resource allocation overlapping with the semi-static frequency resource allocation. That is, SBFD resource allocation may overlap with CSI-RS resource allocation. The UE may implicitly determine the set of sub-bands within the CSI-RS band, for example, by using semi-static frequency resource allocation and frequency resource allocation for the CSI-RS band. In some examples, the set of sub-bands within the CSI-RS band and at least one uplink sub-band associated with the semi-static frequency resource allocation do not overlap. In some cases, multiple sub-bands within the CSI-RS band have guard bands that satisfy a threshold guard band value between the set of sub-bands within the CSI-RS band and at least one uplink sub-band.

[0164] At 1406, UE 104 can receive signaling to configure CSI reports. For example, a CSI report can be used to report one or more measurements of CSI-RS. In some examples, the signaling to configure CSI reports indicates that the CSI report includes a measurement (e.g., a CSI-RS measurement), an indication of obtaining the measurement by measuring SBFD time resources or non-SBFD time resources, an indication of a sub-band subset, or an indication of an error state for at least one measurement. Alternatively, the signaling to configure CSI reports indicates that the CSI report includes one or more CSI values ​​obtained from CSI measurements, an error state for one or more monitoring opportunities scheduled for CSI-RS, an indication of one or more frequency resources from which their CSI values ​​are obtained, or a measurement technique used to obtain the CSI measurements.

[0165] At 1408, UE 104 may receive one or more dynamic indications from NE 102. For example, dynamic indications may include bitmap indications, or any other type of subband inclusion and / or exclusion indications. In some cases, bitmap indications or other subband inclusion and / or exclusion indications may be included in the signaling configuring CSI-RS at 1404. NE 102 may transmit one or more dynamic L1 and / or L2 signaling (e.g., in addition to the signaling at 1404 and 1406).

[0166] At 1410, NE 102 (e.g., or another device) may transmit one or more CSI-RS to UE 104. For example, NE 102 may use one or more time resources allocated for CSI-RS transmission in the CSI band to transmit CSI-RS. NE 102 may transmit CSI-RS at one or more monitoring times (e.g., according to CSI-RS transmission periodicity).

[0167] At 1412, UE 104 may selectively perform one or more CSI-RS measurements on a subset of subbands. For example, UE 104 may selectively perform at least one measurement on a subset of subbands within the CSI-RS band set according to a first signaling and a second signaling. In some examples, UE 104 may receive signaling indicating a subset of subbands. For example, NE102 may include an indication of a subset of subbands in signaling configuring CSI reporting and / or in other signaling. The subset of subbands may contain the initial or first occurrence of CSI-RS.

[0168] In some cases, UE 104 performs measurements on a subband subset based on determining that the measurement is valid for that subband subset. The UE can determine a valid measurement by comparing the bandwidth of the subband with a minimum bandwidth used for the measurement. If the bandwidth meets a threshold (e.g., the minimum bandwidth), the UE can determine the measurement is valid. If the bandwidth fails to meet the threshold (e.g., the minimum bandwidth), the UE can determine the measurement is invalid. Alternatively, UE 104 can determine a valid measurement by comparing the guard band of the corresponding subband and the uplink SBFD subband in the separated subband subset with a threshold. If the guard band meets the threshold (e.g., the minimum value), the UE 104 can determine the measurement is valid. If the guard band fails to meet the threshold (e.g., the minimum value), the UE 104 can determine the measurement is invalid. Alternatively, if the measurement of a sub-band subset is compatible with the capabilities of UE 104 (e.g., the ability to report at 1402), UE 104 may determine that the measurement is valid, and if the measurement of a sub-band subset is not compatible with the capabilities of UE 104, UE 104 may determine that the measurement is invalid.

[0169] In some other cases, based on the determination that the measurement of a sub-band subset is invalid or partially valid, UE 104 prevents the performance of measurements on the sub-band subset and / or a portion of the sub-band. In some cases, based on the start time of the measurement of the sub-band subset within the CSI-RS band, the end time of the measurement of the sub-band subset within the CSI-RS band, or any combination thereof, UE 104 performs measurements for a time period, for a threshold value for the measurement, or for a threshold value for the measurement timing.

[0170] In some examples, UE 104 receives signaling instructing an additional subset of sub-bands from the set of sub-bands scheduled for the occurrence of CSI-RS. If the additional measurement is valid, UE 104 may selectively perform additional measurements on the additional subset of sub-bands. In some examples, if the measurement is associated with the same antenna panel (e.g., as indicated in the control signaling and as referenced...), Figure 12 and 13 As described above, the UE can combine measurements and additional measurements. In some examples, the UE 104 may receive signaling containing one or more parameters that indicate the antenna panel for transmitting CSI-RS in the corresponding subband of the subband set within the CSI-RS band.

[0171] At 1414, UE 104 can transmit a CSI report to NE 102. For example, UE 104 can use signaling to configure the CSI report to determine the information to be included in the CSI report. If the UE performs a measurement at 1412, UE 104 can include one or more CSI-RS measurements in the CSI report.

[0172] In some examples, different steps can be arranged in text and flowcharts to describe example implementations. In practice, each configuration may be provided by one or more configurations. Earlier configurations may provide a subset of parameters, while later configurations may provide another subset of parameters. Alternatively or concurrently, later configurations may override values ​​provided by earlier configurations or pre-configurations. Configurations may be provided via Xn signaling between RAN nodes and / or NG signaling, RRC signaling, MAC signaling, physical layer signaling such as DCI messages, any combination thereof, or other methods. Configurations may include pre-configurations or semi-static configurations provided by standards, vendors, and / or networks and / or operators (e.g., OAM). Each parameter value received by configuration or indication may override previous values ​​used for similar parameters.

[0173] L1 and / or L2 control signaling can refer to control signaling in Layer 1 (e.g., physical layer) or Layer 2 (e.g., data link layer). Specifically, L1 and / or L2 control signaling can refer to L1 control signaling such as DCI messages or UCI messages, L2 control signaling such as MAC messages, or any combination thereof. The format and interpretation of L1 and / or L2 control signaling can be determined by standards, configurations, other control signaling, or any combination thereof.

[0174] In this disclosure, references to messages or information elements are frequently made. In some examples, an information element refers to a configuration at layer 3 and higher. Information elements may be included in messages moving from one layer to another or from one entity to another. Alternatively, another information element may contain an information element. As used herein, the terms 'information element' and 'message' are used interchangeably when a message directly or indirectly contains an information element. Any parameters discussed in this disclosure may, in practice, be expressed as a linear function of the parameters described in signaling or specifications.

[0175] In this disclosure, reference is frequently made to beam indicators. In practice, according to standard specifications, a beam indicator can refer to an indication of a reference signal by an ID or indicator, a resource associated with the reference signal, or spatial relational information containing the reference signal or its reciprocal (in the case of beam correspondence). Although specific types of reference signals, such as CSI-RS, SRS, SSB, etc., are frequently referenced, systems and methods are not limited in scope to specific reference signals. Other types of reference signals may be used in various implementations, which may include reference signals specified for the purposes pursued in this disclosure. Throughout the specification, the terms "parameter" and "value" of a parameter are used interchangeably. A parameter can be a sequence / array of parameters in various implementations.
