[0070] Figures 14 to 17 A flowchart illustrating a method for supporting multi-slot CQI reporting according to various aspects of this disclosure is shown. Detailed Implementation

[0071] In some systems, the base station can transmit signals to the user equipment (UE) using a modulation and coding scheme (MCS) used for transmissions (e.g., downlink data transmissions such as Physical Downlink Shared Channel (PDSCH) transmissions). The base station can determine and apply an appropriate MCS for each transmission based on Channel State Information (CSI) provided by the UE. In some cases, the CSI can be determined by the UE as a result of measuring a reference signal provided by the base station. Therefore, the appropriateness of the applied MCS can be based on the quality of the reference signal measurement performed by the UE.

[0072] When the UE is highly mobile, resulting in a high Doppler effect, CSI measurements and reporting based on a single reference signal may be insufficient to account for changes caused by a rapidly moving UE (e.g., the UE moves above a speed threshold). For example, when the UE is highly mobile, CSI feedback based on a single reference signal may not accurately represent channel quality (e.g., due to channel variations or channel aging).

[0073] Measuring multiple CSI reference signals (RS) in different time slots and reporting them identically can help improve the accuracy of base station determination of the MCS. For different CSI-RS measurements, differences in the reported Channel Quality Information (CQI) can be useful for the base station to identify variations in the MCS over time. In other words, consecutive CSI-RS measurements in different time slots allow the base station to determine the effective “rate of change” in the CQI and thus infer the potential rate of change of the MCS over a similar number of time slots.

[0074] To this end, the UE can identify CSI report configuration or CSI report triggering (e.g., triggering for providing CSI reports to the base station). The UE can receive one or more CSI-RS resources associated with the CSI report. The UE can determine the channel quality of each time slot based on measurements of one or more CSI reference signals received on the time slot set. The UE can transmit a CSI report including the channel quality (e.g., CQI) of two or more time slots in the time slot set during uplink transmission opportunities.

[0075] In the example, for each time slot, the UE can measure at least one of a first channel quality (e.g., wideband CQI) and one or more second channel qualities (e.g., subband CQI) associated with a frequency range of the time slot set, each second channel quality associated with a corresponding subband of the frequency range. In some aspects, the UE can provide differential reporting (e.g., using incremental values) to report the measured channel quality for each time slot. In the CSI report, the incremental values ​​can represent the difference between different rows and / or columns, with each column including measurements for a given time slot and each row including measurements for a given frequency subband or wideband.

[0076] The base station can determine how channel quality changes on a slot-by-slot basis from multi-slot CSI reports. In some cases, if the base station assumes the rate of change of channel quality remains constant, it can adjust the MCS used for continuous transmission based on the multi-slot CSI reports. In other cases, the base station can determine the set of MCS used for downlink data transmission (e.g., PDSCH transmissions) based on received CSI reports or other criteria (e.g., network implementation). The base station can then transmit (and the UE can receive and decode) the set of downlink data transmissions (e.g., PDSCH transmissions) based on the MCS set during transmission timing (e.g., downlink transmission time).

[0077] The aspects of the subject matter described herein can be implemented to achieve one or more advantages. Among other advantages, the described techniques can support improvements in spectral efficiency and reliability. In some aspects, generating multi-slot CSI reports that include the corresponding CQI for each measurement slot can provide increased accuracy to the CSI reports. In some aspects, providing differential reports (e.g., using incremental values) for reporting measured channel quality can provide advantages such as reduced data usage and increased throughput. In some cases where the base station assumes that the rate of change of channel quality remains constant in the differential reports, the base station can adjust the MCS for continuous transmission (e.g., downlink data transmission, such as Physical Downlink Shared Channel (PDSCH) transmission) accordingly based on the multi-slot CSI reports. Therefore, the UE can successfully receive and decode continuous transmissions, which can reduce unnecessary retransmissions, increase throughput, and reduce latency.

[0078] The aspects of this disclosure are initially described in the context of a wireless communication system. Examples of procedures and signaling exchange supporting multi-slot CQI reporting are then described. These aspects are further illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts related to multi-slot CQI reporting.

[0079] Figure 1 An example of a wireless communication system 100 supporting multi-slot CQI reporting is shown according to various aspects of this disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0080] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be different types of devices or devices with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, on which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographical area over which base station 105 and UE 115 can communicate signals supported by one or more radio access technologies.

[0081] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be different types of devices or devices with different capabilities. Figure 1 Some example UE115s are shown in the document. The UE 115 described herein can communicate with various types of devices, such as... Figure 1 Other UEs 115, base stations 105, or network equipment shown (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment).

[0082] Base station 105 can communicate with core network 130, communicate with each other, or both. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) or both via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 can be one or more radio links or include one or more radio links.

[0083] One or more base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, e-node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home e-node B or other suitable terms.

[0084] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances, or vehicles, meters, etc.

[0085] The UE 115 described in this article can communicate with various types of devices, such as... Figure 1The diagram shows other UEs 115 that can sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0086] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the radio spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels of a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operations for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0087] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Extended OFDM (DFT-S-OFDM). In a system employing MCM, a resource element can consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the encoding / decoding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate UE 115 may achieve. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can also increase the data rate or data integrity for communication with UE 115.

[0088] The time interval between base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N fThis can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of a communication resource can be organized based on each radio frame having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0089] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). In some wireless communication systems 100, time slots may also be divided into multiple mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f Sampling period. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0090] A subframe, time slot, mini-slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0091] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by several symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a group of UEs 115. For example, one or more UEs 115 can monitor or search for control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of the control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set can include a common search space set configured to issue control information to multiple UEs 115 and a UE-specific search space set for issuing control information to a specific UE 115.

[0092] In some examples, base station 105 may be mobile, and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0093] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services such as Mission-Critical Push-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData). Support for mission-critical functions can include prioritizing services, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0094] In some examples, UE 115 may also be able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates resource scheduling for D2D communication. In other cases, D2D communication is performed between UE 115s without the involvement of base station 105.

[0095] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and may include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Network operator IP service 150 may include access to the Internet, one or more intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0096] Some network devices, such as base station 105, may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145, which may be referred to as a radio head, smart radio head, or transmit / receive point (TRP). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or combined into a single network device (e.g., base station 105).

[0097] Wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 MHz to 300 GHz. Generally, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is approximately 1 decimeter to 1 meter. UHF waves may be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficiently to enable macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0098] Wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 can employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on a combination of carrier aggregation configuration and component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0099] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be juxtaposed at an antenna fitting such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports, which base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays capable of supporting various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0100] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique can be called spatial multiplexing. Multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiving device and multi-user MIMO (MU-MIMO) in which multiple spatial layers are transmitted to multiple devices.

[0101] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals communicating via antenna elements of an antenna array such that some signals propagating relative to the antenna array in a particular azimuth experience constructive interference, while others experience destructive interference. The adjustment of signals communicating via antenna elements can include the transmitting or receiving device applying amplitude shift, phase shift, or both to the signals carried via the antenna elements associated with that device. The adjustment associated with each antenna element can be defined by a beamforming weight set associated with a particular azimuth (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other azimuth).

[0102] Wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of the RRC connection (which supports radio bearers for user plane data) between UE 115 and base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0103] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique to increase the likelihood of correct data reception over communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support simultaneous time-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in previous symbols within that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0104] UE 115 can identify a CSI reporting configuration or a CSI reporting trigger (e.g., a trigger for providing a CSI report to base station 105). In the example, UE 115 can receive a CSI reporting configuration or a CSI reporting trigger from base station 105. In some aspects, for periodic CSI reporting, UE 115 can receive the CSI reporting configuration via an RRC indicating periodic CSI reporting, and UE 115 can report CSI according to the periodicity and slot offset indicated in the CSI reporting configuration. In some cases, for semi-persistent (SP) CSI reporting, UE 115 can receive the CSI reporting configuration via an RRC indicating semi-persistent CSI reporting, and UE 115 can further receive a MAC-CE to activate SP-CSI reporting or receive downlink control information (DCI) to activate SP-CSI reporting. Once the activation command is received, UE 115 can begin reporting SP-CSI with the periodicity and offset configured in the RRC signaling. UE 115 can also receive a MAC-CE or DCI to disable SP-CSI reporting. In some examples, for aperiodic CSI (A-CSI) reporting, UE 115 can receive CSI reporting configuration via an RRC indicating A-CSI reporting, and UE 115 can also receive a DCI that triggers A-CSI reporting. Once triggered, UE 115 can report A-CSI. UE 115 can receive one or more CSI-RS resources associated with the CSI report. In some aspects, UE 115 can listen to CSI-RS resources for a set of CSI reference signals. In some aspects, UE 115 can determine the channel quality of each time slot based on measurements of one or more CSI reference signals received on the time slot set. UE 115 can send a CSI report including the channel quality (e.g., CQI) of two or more time slots in the time slot set during uplink transmission opportunities.

[0105] In the example, for each time slot, UE 115 can measure at least one of a first channel quality (e.g., wideband CQI) and one or more second channel qualities (e.g., subband CQI) associated with a frequency band of the time slot set, each second channel quality associated with a corresponding subband of the frequency band. For example, if wideband CQI reporting is configured, UE 115 can report the wideband CQI for each time slot in the time slot set. In another example, if subband CQI reporting is configured, UE 115 can report the wideband CQI and differential CQI (relative to WB CQI) for each subband. In some aspects, UE 115 can provide differential reporting (e.g., using incremental values) to report the measured channel quality for each time slot. In the CSI report, the incremental values ​​can represent the difference between different rows and / or columns, with each column including measurements for a given time slot and each row including measurements for a given frequency subband or wideband.

[0106] Base station 105 can determine how channel quality changes on a per-slot basis from CSI reports (e.g., multi-slot CSI reports). In some aspects, base station 105 can determine an MCS set for a set of downlink data transmissions (e.g., PDSCH transmissions) based on CSI reports or based on criteria other than CSI reports (e.g., network implementation). The MCS set can include a corresponding MCS for each downlink data transmission (e.g., PDSCH transmission) in that set. Base station 105 can send a DCI indicating the MCS set and the set of downlink data transmissions (e.g., PDSCH transmissions) to UE 115. Therefore, base station 105 can transmit (and UE 115 can receive and decode) the set of downlink data transmissions (e.g., PDSCH transmissions) based on the MCS set during transmission timing (e.g., downlink transmission time).

[0107] Figure 2 Examples of a wireless communication system 200 supporting multi-slot CQI reporting according to various aspects of this disclosure are shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100 and may include a UE 115-a and a base station 105-a, which may be respectively referenced to... Figure 1 Examples of UE 115 and base station 105 described. Figure 2 An example of communication 201 between UE115-a and base station 105-a is shown.

[0108] refer to Figure 2 UE 115-a and base station 105-a can communicate based on a timeslot configuration indicating the frame structure or timeslot format. For example, frame 205 (e.g., frame n-1) can have a frame structure or timeslot format DDDDDDDSUU, where timeslots 215-a to 215-g are downlink timeslots, timeslot 215-h is a special timeslot (e.g., a timeslot including 14 symbols and a guard period), and timeslots 215-i and 215-j are uplink timeslots. In some aspects, the frame structure or timeslot format (e.g., DDDDDDDSUU) can be applied to additional frames (e.g., subsequent frames in the time domain). For example, frame 210 (e.g., frame n) may include time slots 230 (e.g., time slots 230-a to 230-j), where time slots 230-a to 230-g are downlink time slots, time slot 230-h is a special time slot (e.g., a time slot including 14 symbols and a guard period), and time slots 230-i and 230-j are uplink time slots. Time slot 230 may include aspects of time slot 215.

[0109] UE 115-a can identify a CSI report configuration or a CSI report trigger (e.g., a trigger for providing a CSI report to base station 105-a). In the example, UE 115-a can receive a CSI report configuration or a CSI report trigger from base station 105-a. UE 115-a can receive one or more CSI reference signal (RS) resources associated with a CSI report. In some aspects, UE 115-a can listen to CSI-RS resources for a set of CSI reference signals (e.g., CSI-RS 220-a to CSI-RS 220-c).

[0110] In some aspects, UE 115-a may receive CSI-RS resources (e.g., for listening to CSI-RS 220-a to CSI-RS 220-c) during downlink transmission timing 202. UE 115-a may send CSI reports including channel quality for two or more timeslots 215 (e.g., two or more timeslots 215-c to 215-e). In some aspects, UE 115-a may send CSI reports during uplink transmission timing 203 (e.g., during timeslot 215-j). Timeslot 215 and frame 205 may include references herein. Figure 1 The description covers aspects of time slots and frames.

[0111] In some aspects, UE 115-a can determine the channel quality of each time slot (e.g., time slots 215-c to 215-e) in the set of time slots 215 based on measurements of one or more CSI reference signals (e.g., CSI-RS 220-a to CSI-RS 220-c). In some examples, UE 115-a can receive one or more CSI reference signals (e.g., CSI-RS 220-a to CSI-RS 220-c) through the set of time slots 215 (e.g., time slots 215-c to 215-e). UE 115-a can determine the multi-time slot channel CQI of the time slot 215 on which base station 105-a transmits CSI reference signals (e.g., the time slot 215 on which UE 115-a receives CSI reference signals). In the example, the CSI report configuration received by UE 115-a may include a multi-time slot CQI configuration. UE 115-a can determine the CQI on a multi-slot CSI reference resource (i.e., slots 215-c to 215-e). In some cases, CSI-RS may not overlap with the multi-slot CSI reference resource. In some cases, CSI-RS 220-a to 220-c may overlap with the multi-slot CSI reference resource. UE 115 can determine the CQI for each slot in the set of slots 215 included in the CSI reference resource (i.e., each of slots 215-c to 215-e).

[0112] Each of the sets of CSI reference signals (e.g., CSI-RS 220-a to CSI-RS 220-c) may be associated with a corresponding one of the sets of time slots 215 (e.g., time slots 215-c to 215-e). Alternatively, each of the sets of CSI reference signals (e.g., CSI-RS 220-a to CSI-RS 220-c) may not be associated with a corresponding one of the sets of time slots 215 (e.g., time slots 215-c to 215-e). For example, the sets of time slots 215 (e.g., time slots 215-c to 215-e) of the CSI reference signal sets (e.g., CSI-RS 220-a to CSI-RS 220-c) may or may not be aligned with the time slot set of the CSI reference resource. In some respects, the set of time slots 215 of the CSI reference signal set (e.g., CSI-RS220-a to CSI-RS 220-c) (e.g., time slots 215-c to 215-e) may at least partially overlap with the time slot set of the CSI reference resource. Example aspects of the CSI reference resource will be described later in this document.

[0113] UE 115-a can measure the channel quality (e.g., channel quality information (CQI), where CQI may also be referred to as a channel quality indicator) of each of time slots 215 (e.g., each of time slots 215-c to 215-e) based on CSI measurements of the CSI reference signal set (e.g., CSI-RS 220-a to CSI-RS220-c). UE 115-a can send a CSI report (e.g., a CSI report including CSI feedback (CSF)) to base station 105-a based on the measured channel quality. In some aspects, UE 115 can first identify where the CSI report is sent and, based on that identification, determine the location of the CSI reference resource (indicating that the UL time slot of the CSI report is n). ′ Then the CSI reference resource in time slot nn ref Among them and μ DL and μ UL These represent the subcarrier spacing (SCS) of the carrier measured by CSI and the carrier reported by CSI, respectively. For example, the n_ref slot (e.g., reference...) Figure 3 The n_CSI_ref slot (also referred to herein as n_CSI_ref slot) can be equal to five (5) slots (e.g., as shown in 225). In the example, UE 115-a may send a CSI report to base station 105-a during uplink transmission time 203. In some examples, UE 115-a may send a CSI report to base station 105-a within CSF 221 of slot 215-j (e.g., the CSI report slot).

[0114] In some respects, for periodic or semi-persistent CSI reports, if a single CSI report is to be sent and slot n-n_ref is a valid downlink slot, then the CSI reference resource can be n_ref = the smallest integer of four (4) slots prior to the CSI report slot (assuming the same SCS for the carrier used for CSI reporting and the carrier used for CSI measurement; alternatively, for different SCS for the carrier used for CSI reporting and the carrier used for CSI measurement, n_ref can be based on the equation (To calculate). In some cases, if there are multiple CSI reports to be sent, the CSI reference resource can be n_ref = the smallest integer greater than or equal to five (5) slots before the CSI report slot (assuming the SCS of the carrier used for CSI reporting and the carrier used for CSI measurement are the same; alternatively, for different SCS of the carrier used for CSI reporting and the carrier used for CSI measurement, n_ref can be based on the equation (to calculate), and slot n-n_ref is a valid downlink slot. For non-periodic CSI reports, the CSI reference resource can be the smallest integer n_ref = the slots greater than or equal to the lower limit (Z' / 14) before the CSI report slot, and slot n-n_ref is a valid downlink slot. Z' is the A-CSI processing timeline, which is determined by several factors. If there are WB CSI <= four (4) ports, a single CSI-RS resource, no uplink data, no HARQ-ACK, and no occupied central processing unit (CPU) before processing the CSI, a fast timeline (Table 1 below) can be used.

[0115]

[0116] Table 1

[0117] Otherwise, if WB CSI <= four (4) ports, a single CSI-RS resource, Type I CSI, or a non-PMI-based CSI report, the Z1' value in the lower timeline table can be used. Otherwise, if the CSI report is related to beam management, the Z3' value in the lower timeline table can be used. Otherwise, the Z2' value in the lower timeline table (Table 2 below) can be used.

[0118]

[0119] Table 2

[0120] Therefore, in some respects, n_ref can be used for multi-slot CSI reference resources, where the last slot of the multi-slot CSI reference resource is n_ref before the CSI report (i.e., the CSI report slot), and n_ref can follow the same rules as described above. More specifically, n_ref represents the uplink slot for the CSI report. ′ Then the last slot of the multi-slot CSI reference resource is in slot nn. ref Among them and μ DL and μ UL These represent the SCS of the carrier measured by CSI and the carrier reported by CSI, respectively.

[0121] A CSI report may include multi-slot CQIs for reporting channel quality variations (e.g., CQI variations) across a set of time slots 215 (e.g., time slots 215-c to 215-e). For example, a CSI report may include measured channel quality for the measurement time slots of the set of time slots 215. In some examples, a CSI report may include corresponding CQIs for two or more time slots from time slots 215-c to 215-e. In some aspects, a CSI report may include a first channel quality (e.g., wideband CQI) associated with a frequency range (e.g., wideband). In some other aspects, a CSI report may include one or more second channel qualities (e.g., subband CQIs), each second channel quality associated with a corresponding subband of the frequency range. Example aspects of first and second channel qualities are described herein. In an example, a CSI report may include precoding matrix indicators (PMIs) and corresponding CQIs for three (3) sets of CSI-RS resources (e.g., CSI-RS resources corresponding to time slots 215-c to 215-e, respectively). In some respects, CSI reports may include CSI-RS Resource Indicators (CRI), CQI, PMI, and Order Information (RI).

[0122] In some aspects, UE 115-a can calculate the CSI (e.g., CQI) in a CSI reference resource. For example, when determining the channel quality of each of time slots 215 (e.g., time slots 215-c to 215-e), UE 115-a can determine the channel quality in a CSI reference resource comprising multiple time slots. The CSI reference resource may include time slots 215-c to 215-e. In some other aspects, the CSI reference resource may include time slots other than time slots 215-c to 215-e. For example, the CSI reference resource may include some of time slots 215-c to 215-e and some of the downlink time slots (such as any one of time slots 215-a, 215-b, 215-f, and 215-g). In some aspects, the CSI reference resource may include a set of time slots that at least partially overlap with time slots 215-c to 215-e.

[0123] UE 115-a can determine the number of time slots included in the CSI reference resource and the time slot intervals associated with the number of time slots based on one or more predetermined values. In some aspects, UE 115-a can determine the number of time slots included in the CSI reference resource and the time slot intervals based on the configuration sent by base station 105-a via RRC messages or MAC control elements (MAC-CE). UE 115-a can determine the set of time slots 215 (e.g., time slots 215-c to 215-e, or downlink time slots including or excluding time slots 215-c to 215-e) based on the determined number of time slots and time slot intervals.

[0124] In some respects, UE 115-a can determine the location of the CSI reference resource based on the number of time slots between the last time slot 215 (e.g., time slot 215-e) of the CSI reference resource and the uplink time slot 215 (e.g., time slot 215-j) used to send the CSI report. UE 115-a can determine the number of time slots between the last time slot 215 (e.g., time slot 215-e) of the CSI reference resource and the uplink time slot 215 (e.g., time slot 215-j) based on the report type associated with the CSI report (i.e., by determining n_ref as described above). The report type can be, for example, a periodic report, a semi-persistent report, or a non-periodic report. (References herein) Figure 3 Further description of CSI reference resources and example aspects of determining channel quality (e.g., CSI, CQI) based on CSI reference resources.

[0125] Base station 105-a can determine a set of MCSs for a set of downlink data transmissions (e.g., PDSCH 231-a to PDSCH 231-c) for the next frame (e.g., frame 210 (e.g., frame n)). This set of downlink data transmissions (e.g., PDSCH 231-a to PDSCH 231-c) can correspond to a set of time slots 230 (e.g., time slots 230-d to time slots 230-f). In some aspects, base station 105-a can determine the MCS set based on a CSI report or based on criteria other than a CSI report (e.g., based on network implementation). In some aspects, the MCS set can include a corresponding MCS for each downlink data transmission in the downlink data transmission set (e.g., a corresponding MCS for each of PDSCH 231-a to PDSCH 231-c). In the example, the set of time slots (e.g., time slots 230-d to time slots 230-f) can be associated with downlink transmission timing 204. In some examples, base station 105-a may apply four (4) time slots after receiving, for example, CSI report 225 (as indicated by 235), which can illustrate the amount of time used to schedule the downlink data transmission set (e.g., PDSCH 231-a to PDSCH 231-c).

[0126] In some aspects, base station 105-a can send a DCI to UE 115-a. The DCI can indicate a set of MCSs and a set of downlink data transmissions (e.g., PDSCH 231-a to PDSCH 231-c). Therefore, base station 105-a can send (and UE 115-a can receive and decode) the downlink data transmission sets (e.g., PDSCH 231-a to PDSCH 231-c) based on the MCS set during downlink transmission timing 204. In some cases, UE 115-a can successfully receive and decode the downlink data transmission sets (e.g., PDSCH 231-a to PDSCH 231-c), and in some examples, a positive acknowledgment is sent for the downlink data transmission sets (e.g., PDSCH 231-a to PDSCH 231-c). For example, UE115-a can transmit ACK 240-a corresponding to PDSCH 231-a, ACK 240-b corresponding to PDSCH 231-b, and ACK 240-c corresponding to PDSCH 231-c in the Physical Uplink Control Channel (PUCCH) 232 included in time slot 230-h.

[0127] refer to Figure 2The described aspects of the technology can be superior to some systems, for example, by providing an MCS that can take into account channel quality variations (and CQI variations) across a set of time slots 215 (e.g., time slots 215-c to 215-e). In some other systems, for example, the UE can receive an indication of a single time slot for providing a channel quality estimate. In some cases, the UE can receive a reference signal (e.g., CSI-RS 220-a) from the base station, based on which the UE can provide a channel estimate (e.g., CQI) for a single time slot (e.g., time slot 215-c). In some systems, the UE can provide CSI feedback (e.g., CSI, CQI) to the base station relative to a single time slot (e.g., time slot 215-c) and the reference signal (e.g., CSI-RS 220-a). In some systems, using CSI feedback, the base station can apply the same MCS (and code rate) to transmit multiple scheduled downlink data transmissions to the UE (e.g., PDSCH 231-a to PDSCH 231-c).

[0128] However, CSI feedback provided by a reference signal (e.g., CSI-RS 220-a) based on a single time slot (e.g., time slot 215-c) may not accurately represent channel quality relative to time (e.g., due to channel variations or channel aging, e.g., in high Doppler scenarios). For example, for TDD, HARQ-ACK delays may be relatively large due to limited uplink resources, potentially leading to inefficient MCS adjustments by the base station to transmit signals to the UE. In some systems, applying the same MCS scheme (and code rate) may be suitable for transmitting scheduled downlink data transmissions (e.g., PDSCH 231-a to PDSCH 231-c) for the channel conditions corresponding to the CSI feedback (e.g., the channel conditions when the UE measures channel quality), but may be insufficient for different channel conditions (e.g., relatively poor channel conditions). In some systems, when using the same MCS scheme, the UE may not be able to successfully decode all scheduled downlink data transmissions (e.g., PDSCH 231-a to PDSCH 231-c). For example, in some systems, a UE may be able to successfully decode the first scheduled downlink data transmission encoded using the MCS scheme (e.g., the UE may send an ACK for PDSCH 231-a), but may not be able to successfully decode subsequent scheduled downlink data transmissions encoded using the same MCS scheme (e.g., the UE may send negative acknowledgments for PDSCH 231-b and PDSCH 231-c). In other words, the MCS scheme used by the base station may become obsolete, leading to reduced throughput and spectral efficiency.

[0129] According to aspects of the technology described herein, for each time slot (e.g., each of time slots 215-c to 215-e) in the set of time slots 215 indicated in the configuration received from base station 105-a, UE 115-a can measure a first channel quality (e.g., wideband CQI) associated with a frequency range (e.g., wideband) of the set of time slots 215 (e.g., time slots 215-c to 215-e). In some aspects, UE 115-a can measure one or more second channel qualities (e.g., subband CQI), each second channel quality associated with a corresponding subband of the frequency range. For example, based on a network configuration of wideband CQI, UE 115-a can measure the first channel quality (e.g., wideband CQI). In another example, based on a network configuration of subband CQI, UE 115-a can measure the first channel quality (e.g., wideband CQI) and one or more second channel qualities (e.g., subband CQI).

[0130] In some aspects, for additional time slots (e.g., time slot 215-d, time slot 215-e), UE 115-a may generate a CSI report (e.g., a CSF report) to include multiple first measured channel quality (e.g., wideband CQI), each first measured channel quality corresponding to a first channel quality (e.g., wideband CQI) measured in the corresponding time slot (e.g., time slot 215-c). In some aspects, for additional time slots (e.g., time slot 215-d, time slot 215-e), UE 115-a may generate a CSI report (e.g., a CSF report) to include multiple second measured channel quality (e.g., subband CQI), each second measured channel quality corresponding to a second channel quality (e.g., subband CQI) measured in a subband spanning one of the time slot sets (e.g., time slot 215-c). In some examples, UE 115-a can generate each of the first measured channel quality (e.g., each of the broadband CQIs for time slots 215-c to 215-e) based on the same CRI, the same PMI, and the same RI. In some other examples, UE 115-a can generate each of the second measured channel quality associated with the same subband based on the same CRI, the same PMI, and the same RI (e.g., generating subband CQIs for the same subbands for time slots 215-c to 215-e).

[0131] UE 115-a can provide differential reports (e.g., using incremental values) to report measured channel quality for each time slot in the set of time slots 215 (e.g., each of time slots 215-c to 215-e). In some cases, the differential report can be self-contained for each time slot in the set of time slots 215 (e.g., each of time slots 215-c to 215-e). For example, measurements within each time slot (e.g., time slot 215-c) can include incremental values ​​relative to another measurement within the same time slot, examples of which are described with reference to Table 1. In some other cases, the differential report can be self-contained for the first time slot (e.g., time slot 215-c), and differential reports for additional time slots (e.g., time slots 215-d, time slot 215-e) can be relative to a reference time slot (e.g., the first time slot, e.g., time slot 215-c). For example, measurements within each additional time slot (e.g., time slot 215-d) may include incremental values ​​relative to measurements (or multiple measurements) within a reference time slot (e.g., the first time slot, e.g., time slot 215-c), examples of which are described with reference to Tables 2 and 3. (Refer to Tables 1 through 3 and...) Figure 2 In the example, "time slot 1" can correspond to time slot 215-c, and "time slot 2" can correspond to time slot 215-d (or time slot 215-e).

[0132] Table 1 below shows examples of the first measurement channel quality (e.g., wideband CQI) and the second measurement channel quality (e.g., subband CQI, such as CQI of subband 1 (SB1) to CQI of subband N (SBN)) for each of time slots 1 and 2. Referring to Table 1, each of the second measurement channel quality (e.g., subband CQI) of a corresponding time slot can be indicated by an incremental value relative to the first measurement channel quality (e.g., wideband CQI) of the corresponding time slot. For example, referring to time slot 1, the second measurement channel quality (e.g., CQI of SB1) can be indicated by an incremental value (e.g., dCQI1.1) relative to the first measurement channel quality (e.g., CQI1), and another second measurement channel quality (e.g., CQI of SB2) can be indicated by an incremental value (e.g., dCQI1.2) relative to the first measurement channel quality (e.g., CQI1). In another example, referring to time slot 2, the second measurement channel quality (e.g., CQI of SB1) can be indicated by an increment value (e.g., dCQI2.1) relative to the first measurement channel quality (e.g., CQI2), and another second measurement channel quality (e.g., CQI of SB2) can be indicated by an increment value (e.g., dCQI2.2) relative to the first measurement channel quality (e.g., CQI2).

[0135] Table 2 below shows examples of the first measurement channel quality (e.g., wideband CQI) and the second measurement channel quality (e.g., subband CQI, such as CQI of SB1 to CQI of SBN) for each of time slots 1 and 2. Referring to time slot 1, the second measurement channel quality (e.g., CQI of SB1 to CQI of SBN) can be indicated by an increment (e.g., dCQI1.1 to dCQI1.N) relative to the first measurement channel quality (e.g., CQI1). For an additional time slot (e.g., time slot 2), each of the first measurement channel quality (e.g., wideband CQI) and the second measurement channel quality (e.g., subband CQI) can be indicated by an increment (e.g., dCQI2.0) relative to the first measurement channel quality (e.g., wideband CQI) of the first time slot (e.g., time slot 1). For example, for time slot 2, the first measurement channel quality (e.g., wideband CQI) can be indicated by an increment (e.g., dCQI2.0) relative to the first measurement channel quality (e.g., CQI1) of time slot 1. The second measurement channel quality (e.g., CQI of SB1) in time slot 2 can be indicated by an increment (e.g., dCQI2.1) relative to the first measurement channel quality (e.g., CQI1) in time slot 1. Another second measurement channel quality (e.g., CQI of SB2) in time slot 2 can be indicated by an increment (e.g., dCQI2.2) relative to the first measurement channel quality (e.g., CQI1) in time slot 1.

[0138] Table 3 below shows examples of the first measured channel quality (e.g., wideband CQI) and the second measured channel quality (e.g., subband CQI, such as CQI of SB1 to CQI of SBN) for each of time slots 1 and 2. Referring to time slot 1, the second measured channel quality (e.g., CQI of SB1 to CQI of SBN) can be indicated by an incremental value (e.g., dCQI1.1 to dCQI1.N) relative to the first measured channel quality (e.g., CQI1).

[0139] For an additional time slot (e.g., time slot 2), each of the first measurement channel quality (e.g., wideband CQI) and the second measurement channel quality (e.g., subband CQI) can be indicated by an increment of the corresponding first measurement channel quality (e.g., wideband CQI) or second measurement channel quality (e.g., subband CQI) relative to the first time slot (e.g., time slot 1). For example, for time slot 2, the first measurement channel quality (e.g., wideband CQI) can be indicated by an increment of the first measurement channel quality (e.g., CQI1) relative to time slot 1 (e.g., dCQI2.0). The second measurement channel quality of time slot 2 (e.g., CQI of SB1) can be indicated by an increment of the first measurement channel quality (e.g., CQI1) or the second measurement channel quality (e.g., CQI1+dCQI1.1) relative to time slot 1 (e.g., dCQI2.1). Another second measurement of channel quality in time slot 2 (e.g., CQI of SB2) can be indicated by an increment (e.g., dCQI2.2) relative to the first measurement of channel quality in time slot 1 (e.g., CQI1) or the second measurement of channel quality (e.g., CQI1+dCQI1.2). In some respects, using differential reporting (e.g., using increment values) for reporting measured channel quality can provide advantages such as reduced data usage and increased throughput.

[0141]

[0142]

[0143] Reference Figure 2In an example of differential reporting, the CSI report generated by UE 115-a may include the corresponding measured channel quality (e.g., wideband CQI, subband CQI) for a set of time slots 215 (e.g., time slots 215-c to 215-e). For example, the CSI report may include the measured channel quality for time slot 215-c (e.g., CQI1), the measured channel quality for time slot 215-d (e.g., CQI2 = CQI1 + dCQI1), and the measured channel quality for time slot 215-e (e.g., CQI3 = CQI2 + dCQI2). In some aspects, base station 105-a may determine the set of MCSs for scheduled downlink data transmission (e.g., PDSCH 231-a to PDSCH 231-c) for the next frame (e.g., frame 210) based on differential reporting (e.g., based on incremental values) or based on criteria other than differential reporting (e.g., based on network implementation). In the example, base station 105-a can determine the MCS1 for PDSCH 231-a based on CQI1, the MCS2 for PDSCH 231-b based on dCQI1, and the MCS3 for PDSCH 231-c based on dCQI2.

[0144] Figure 3 An example of configuration 300 supporting multi-slot CQI reporting according to various aspects of this disclosure is shown. In some examples, configuration 300 may be implemented by various aspects of wireless communication systems 100 or 200. Configuration 300 may be a reference Figure 2 Frame 205 describes an example of the configuration. Configuration 300 may include time slots 310 (e.g., time slots 310-a to 310-h), which may be referenced. Figure 2 Examples of some of the described time slots 215 (e.g., time slots 215-c to 215-j). In example configuration 300, time slots 310-a to 310-e are downlink time slots, time slot 310-f is a special time slot (e.g., a time slot including 14 symbols and a guard period), and time slots 310-g and 310-h are uplink time slots.

[0145] refer to Figure 2 and Figure 3Configuration 300 can indicate a CSI reference resource for a set of time slots 310 (e.g., a combination of time slots 310-a to 310-e, or a combination of time slots 310-a to 310-c or time slots 310-c to 310-e). Time slot 310-a can be referred to as time slot n-7, and time slot 310-h can be referred to as time slot n. In one example, in the time domain, the CSI reference resource can include multiple time slots ending at time slot 310 (e.g., any one of time slots 310-b to 310-e), which are the number of time slots preceding time slot 310-h used for CSI reporting carrying multi-time slot CQI. In some aspects, the parameter n_CSI_ref (also referred to herein as n_ref) can be used to indicate to UE 115-a the number of time slots preceding time slot 310-h.

[0146] CSI reference resources can be artificial or virtual time slots in which CQI can be calculated. The location of a CSI reference resource can be defined using an offset relative to the time slot used for CSI reporting (e.g., time slot 310-h of uplink transmission time 301, during which UE 115-a can transmit CSF 315). A CSI reference resource can be different from the CSI-RS resource described herein, as a CSI-RS resource can refer to the physical resource on which CSI-RS can be transmitted. For example, the configuration of a CSI-RS resource can include the number of ports and the resource mapping of the ports (e.g., code division multiplexing (CDM) type, resource elements and symbol positions in each resource block, CSI-RS density, etc.). A CSI reference resource may or may not overlap with the actually transmitted CSI-RS.

[0147] In the example, UE 115-a can determine the number of timeslots 310 included in the CSI reference resource (e.g., a combination of timeslots 310-a to 310-e) and the timeslot interval associated with the number of timeslots based on one or more predetermined values. In some other aspects, UE 115-a can determine the number of timeslots 310 included in the CSI reference resource (e.g., a combination of timeslots 310-a to 310-e) and the timeslot interval based on a configuration sent by base station 105-a via an RRC message or MAC-CE. UE 115-a can determine the location of the CSI reference resource based on the number of timeslots between the last timeslot 310 of the CSI reference resource (e.g., timeslot 310-c, timeslot 310-j) and the uplink timeslot 310 used to send the CSI report (e.g., timeslot 310-h). UE 115-a can determine the number of time slots between the last time slot 310 of the CSI reference resource (e.g., time slot 310-c, time slot 310-e) and the uplink time slot 310 (e.g., time slot 310-h) based on the report type associated with the CSI report. The report type can be, for example, a periodic report, a semi-persistent report, or a non-periodic report.

[0148] In the example of periodic or semi-persistent reporting, UE 115-a may use one or more CSI-RS resources and a subcarrier spacing of 15 kHz to send a CSI report to base station 105-a. In the example of periodic or semi-persistent reporting, the parameter n_CSI_ref may be equal to the number of five (5) time slots, and the CSI reference resources may be associated with time slots 310-a (e.g., time slot n-7) to 310-c (e.g., time slot n-5). That is, the CSI reference resources may end at time slot 310-c. As indicated in 320, time slot 310-c may be the last time slot included in the sent CSI report. In the example of non-periodic reporting, UE 115-a may use a 4-port (or greater) type I / II CSI report and a subcarrier spacing of 15 kHz to send a CSI report to base station 105-a. In the example of non-periodic reporting, the parameter n_CSI_ref can be equal to the number of three (3) slots, and the CSI reference resource can be associated with slots 310-c (e.g., slot n-5) to 310-e (e.g., slot n-3). For example, UE 115-a can utilize the rules for determining Z' as described above. In one example, the CSI can be a Type II CSI with 32 ports, SCS = 15kHz, thus avoiding the use of Z2' with a low timeline table, and Z2' = 37. Note here that the lower bound (37 / 14) = two (2), but since n-2 is not a valid downlink slot, n_CSI_ref (also referred to as n_ref in this document) should be three (3). n_ref is the smallest integer greater than or equal to floor (37 / 14) such that the CSI reference slot is a valid downlink slot. In some respects, the CSI reference resource can end at slot 310-e. As indicated in 325, slot 310-e may be the last slot included in the sent CSI report.

[0149] In some aspects, the time slot interval of the set of time slots 310 (e.g., any one of time slots 310-a to 310-e for multi-slot CQI reporting) can be equal to the number of zero time slots. For example, the set of time slots 310 (e.g., time slots 310-a to 310-c, time slots 310-c to 310-e) can be continuous (e.g., in the time domain). In some other aspects, the time slot interval of the set of time slots 310 (e.g., any one of time slots 310-a to 310-e for multi-slot CQI reporting) can be equal to the number of one or more time slots. For example, the set of time slots 310 (e.g., time slots 310-a, 310-c, and 310-e) can be discontinuous (e.g., in the time domain).

[0150] In some cases, UE 115-a can identify invalid time slots used for CQI calculation from a CSI reference resource that includes multiple time slots. For example, UE 115-a can identify time slots with nominal CSI reference time slots (e.g., time slots used for multi-time slot CQI reporting determined by the number of time slots and the time slot interval) as invalid time slots based on time slot type (e.g., downlink time slot, uplink time slot). In some aspects, UE 115-a can avoid measuring the channel quality of the identified invalid time slots (e.g., time slot 310-d). UE 115-a can identify valid time slots (e.g., time slot 310-c) based on the time slot type (e.g., downlink time slot, uplink time slot) before or after the identified invalid time slots, and in some examples, measure the channel quality of the identified valid time slots (e.g., time slot 310-c).

[0151] For example, the time slot format (e.g., for ten (10) time slots, time slots 1 to 10) can be DDDUUDDDSU, and the nominal time slots of the CSI reference time slots (e.g., the nominal time slots of a multi-time slot CSI reference resource) can include time slots 2, 4, and 6. In the example, UE 115-a can determine that time slot 4 is an invalid time slot (e.g., not a downlink time slot). UE 115-a can identify time slot 3 as a valid time slot (e.g., a downlink time slot before or after an invalid time slot). UE 115-a can select time slots 2, 3, and 6 as time slots for multi-time slot CQI reporting (e.g., measuring and reporting CQI for time slot 3 instead of time slot 4).

[0152] In some examples, UE 115-a can determine the CQI of each of multiple time slots in a CSI reference resource, assuming that each of the multiple time slots has the same time slot format. For example, UE 115-a can measure the channel quality of each time slot in a set of time slots 310 (e.g., any combination of time slots 310-a to 310-e, such as time slots 310-a to 310-c or time slots 310-c to 310-e) based on the same time slot format (e.g., according to the downlink signal in the time slot). In some examples, for CSI reference resources, the time slot format of each time slot in the set of time slots 310 may include the number of OFDM symbols occupied by control signaling, the number of combinations of PDSCH symbols and demodulation reference signal (DMRS) symbols, the bandwidth configured for CQI reporting, the ratio of PDSCH energy (EPRE) per resource element to CSI-RS EPRE, the number of DMRS symbols, the assumption that PDSCH symbols do not include DMRS, the physical resource block (PRB) bundle size for which DMRS and PDSCH are equal to two PRBs, and any combination of PMIs.

[0153] Figure 4A and Figure 4B Example transmissions 400 and 401 supporting multi-slot CQI reporting are shown according to aspects of this disclosure. In some examples, transmissions 400 and 401 may be implemented by aspects of wireless communication systems 100 or 200. Transmissions 400 and 401 may be references. Figure 2 An example of multi-stage transmission for base station 105-a is described herein. According to the examples of aspects described herein, base station 105-a may transmit a set (or cluster) of reference signals (e.g., CSI-RS) based on an aperiodic reporting type (e.g., aperiodic CSI (A-CSI) based on periodic, semi-persistent, and aperiodic CSI-RS resources), a periodic reporting type (e.g., periodic CSI based on periodic CSI-RS resources), or a semi-persistent reporting type (e.g., semi-persistent CSI based on both periodic and semi-persistent CSI-RS resources).

[0154] In some aspects of aperiodic configurations (aperiodic report types, aperiodic CSI-RS resources), UE 115-a may receive multi-stage transmissions of each of one or more CSI-RS resources on a set of time slots, wherein each stage of the multi-stage transmission may be transmitted by base station 105-a in one time slot of that set of time slots. For example, base station 105-a may transmit CSI-RS resources in K time slots (e.g., three (3) time slots) during each transmission timing 405 (e.g., downlink transmission timing). In some aspects, K may be the number of time slots and may be equal to an integer value. In some other aspects, the K time slots may have a time slot interval of M time slots between the time slots of the K time slots and another time slot of the K time slots (where M may be an integer value). In the example of aperiodic CSI-RS resources, base station 105-a may transmit CSI-RS resources in time slot n, time slot n+M, time slot n+2M, ... and time slot n+(K-1)×M. Base station 105-a can send configurations indicating the number of time slots (e.g., K) and the time slot interval (e.g., M) via RRC messages or MAC-CE.

[0155] Reference Figure 4AIn the example of the described aperiodic configuration (aperiodic report type, aperiodic CSI-RS resource), base station 105-a can transmit (and UE 115-a can receive) aperiodic CSI-RS resource transmission 400 in a set of time slots (e.g., time slots 410-a to 410-c) during transmission timing 405. Time slot 410-a can be time slot n, time slot 410-b can be time slot n+1, and time slot 410-c can be time slot n+2. In the example, UE 115-a can receive A CSI-RS 416-a to A CSI-RS 416-c in time slots 410-a to 410-c respectively. In some aspects, base station 105-a can send A-CSI request 415 to UE 115-a through the CSI-RS resource of time slot 410-a. UE 115-a can generate a CSI report based on A-CSI request 415 and send it to base station 105-a. A-CSI request 415 can be referred to as CSI report triggering.

[0156] In some aspects of periodic or semi-persistent configurations (periodic or semi-persistent report types, periodic or semi-persistent CSI-RS resources), for each transmission opportunity of each of the periodic or semi-persistent CSI-RS resources, UE115-a may receive multi-stage transmissions of one or more CSI-RS resources on a time slot set. Each time slot in the multi-stage transmission may be transmitted by base station 105-a in one time slot of the time slot set. For example, base station 105-a may transmit the CSI-RS resource set multiple times (e.g., once for each of multiple transmission opportunities). For example, base station 105-a may transmit the CSI-RS resource set during each of transmission opportunities 420, 435, and 440. Each of transmission opportunities 420, 435, and 440 may be a downlink transmission opportunity. For example, base station 105-a can transmit each of the CSI-RS resource sets in K time slots (e.g., three (3) time slots) associated with each of transmission time slots 420, 435 and 440.

[0157] In some aspects, K time slots may have a time slot interval of M time slots between one time slot of K time slots and another time slot of K time slots. In examples of periodic or semi-persistent CSI-RS resources, for the s-th transmission opportunity with period T, base station 105-a may transmit CSI-RS resources in time slots n+(s-1)*T, n+(s-1)*T+M, n+(s-1)*T+2M, ... and n+(s-1)*T+(K-1)*M. In some examples, aspects of wireless communication system 100 or 200 may support multi-slot CQI reporting for low periodicity (e.g., periodicity of four (4) or more time slots but less than ten (10) time slots). Base station 105-a may transmit a configuration indicating the number of time slots (e.g., K) and the time slot interval (e.g., M) via RRC messages or MAC-CE.

[0158] Reference Figure 4B In the example of the described periodic or semi-persistent configuration, base station 105-a may transmit (and UE 115-a may receive) a first multi-stage transmission of periodic or semi-persistent CSI-RS resources in a set of time slots (e.g., time slots 425-a to 425-c) during transmission timing 420. Time slot 425-a may be time slot n, time slot 425-b may be time slot n+1, and time slot 425-c may be time slot n+2. In the example, UE 115-a may receive A CSI-RS 430-a to A CSI-RS 430-c in time slots 425-a to 425-c, respectively. Base station 105-a may transmit (and UE 115-a may receive) a second multi-stage transmission of periodic or semi-persistent CSI-RS resources in a set of time slots (e.g., time slots 425-d to 425-f) during transmission timing 435. Time slot 425-d can be time slot n+9, time slot 425-e can be time slot n+10, and time slot 425-f can be time slot n+2. In the example, UE 115-a can receive ACSI-RS 430-d to ACSI-RS 430-f in time slots 425-d to 425-f respectively.

[0159] Base station 105-a can transmit (and UE 115-a can receive) a third multi-stage transmission of periodic or semi-persistent CSI-RS resources in a set of time slots (e.g., time slots 425-g to 425-i) during transmission timing 440. Time slot 425-g can be time slot n+19, time slot 425-h can be time slot n+20, and time slot 425-i can be time slot n+21. In the example, UE 115-a can receive A CSI-RS 430-g to A CSI-RS 430-i in time slots 425-g to 425-i, respectively. Transmission timings 420 to 440 can be transmission timings 0 to 2, respectively.

[0160] In some aspects, base station 105-a can transmit a single-slot CSI-RS transmission even when repeated "on". In some systems, repeated "on" can be used for beam management. The network can configure the CSI reporting configuration with the number of reports set to "none", and this report is linked to the set of resources that are repeated "on". When repeated "on", each resource can be transmitted by base station 105-a using the same spatial transmission filter (e.g., the same spatial beam). UE 115 can use different receive beams to receive each resource and determine the optimal receive beam for the spatial transmission filter typically used across repeated resources. Therefore, since this process is used for receive beam determination, UE 115 can avoid reporting anything. In some aspects, base station 105-a can transmit each CSI-RS resource in a corresponding time slot.

[0161] In some respects, for multi-slot CQI reporting, there may be no CRI report for a single CSI-RS transmission that is repeatedly “on” because all resources may be duplicated. For example, based on the CRI, UE 115-a can identify (e.g., assuming) that base station 105-a has transmitted the same CSI-RS resource repeatedly (e.g., multiple times in multiple time slots (e.g., eight (8) times)). Based on the assumption of UE 115-a and the transmission via the repeated same CSI-RS resource, UE 115-a can provide multi-slot CQI reporting as described herein.

[0162] For example, in the case of multiple resources in some other systems, the UE can report a CRI indicating that the UE has selected one of multiple resources for CSI calculation. Based on the example of the aspect described herein, UE 115-a can assume transmissions via repeated identical CSI-RS resources, where multiple CSI-RS resources are actually the same CSI-RS resource (e.g., transmitted by base station 105-a in the same implementation). Therefore, UE 115-a can avoid reporting the CRI, and UE 115-a can use the CSI-RS resource to calculate the multi-slot CQI because the CSI-RS resource is transmitted in different time slots.

[0163] Figure 5 An example of a processing flow 500 supporting multi-slot CQI reporting according to various aspects of this disclosure is shown. In some examples, processing flow 500 may implement various aspects of wireless communication system 100 or 200. Processing flow 500 may be implemented by UE 115-b and base station 105-b, which may be references Figure 1 The UE 115 and base station 105 described and referenced Figure 1 Examples of UE 115-a and base station 105-a described.

[0164] In the following description of processing flow 500, operations between UE 115-b and base station 105-b may be transmitted in a different order than shown, or operations performed by base station 105-b and UE 115-b may be performed in a different order or at different times. Some operations may also be omitted from processing flow 500, or other operations may be added to processing flow 500. It should be understood that although some operations of processing flow 500 are shown to be performed by base station 105-b and UE 115-b, any wireless device can perform the operations shown.

[0165] At position 505, UE 115-b can identify the CSI reporting configuration or the trigger for providing a CSI report. In the example, UE 115-a can receive the CSI reporting configuration or the trigger for providing a CSI report from base station 105-a.

[0166] At 510, UE 115-b can receive one or more CSI-RS resources associated with a CSI report.

[0167] At 515, UE 115-b can determine the channel quality of each time slot in the time slot set based on measurements of one or more CSI reference signals. For example, UE 115-b can measure a first channel quality (e.g., wideband CQI) associated with a frequency range of the time slot set for each time slot. In some aspects, UE 115-b can measure one or more second channel qualities (e.g., subband CQI) for each time slot in the time slot set, each second channel quality associated with a corresponding subband of the frequency range. In some examples of determining the channel quality of each time slot in the time slot set, UE 115-b can determine the channel quality in a CSI reference resource comprising multiple time slots. UE 115-b can determine the number of time slots included in the CSI reference resource and the time slot interval associated with that number of time slots based on one or more predetermined values ​​or based on a configuration sent by base station 105-b via an RRC message or MAC-CE.

[0168] In some aspects, at point 515, UE 115-b can determine a multi-slot CSI-RS transmission or a multi-slot CSI reference resource, and then perform CSI measurements or calculations based on that determination. For example, in determining the channel quality of each slot in a set of slots, UE 115-b can determine the channel quality in a CSI reference resource comprising multiple slots. In some aspects, UE 115-b can determine the location of the CSI reference resource based on the number of slots between the last slot of the CSI reference resource and the uplink slot used to send the CSI report. In some examples, UE 115-b can determine the number of slots between the last slot of the CSI reference resource and the uplink slot based on the report type associated with the CSI report, where the report type includes periodic reports, semi-persistent reports, or non-periodic reports. In some examples, UE115-b can determine the number of time slots included in the CSI reference resource and the time slot interval associated with that number of time slots based on one or more predetermined values ​​or based on the configuration sent by base station 105-b via RRC messages or MAC-CE.

[0169] At 520, UE 115-b may transmit a CSI report including channel quality for two or more time slots in the time slot set during uplink transmission opportunities. In some aspects, UE 115-b may generate (and report) a CSI report to include at least one of a plurality of first measured channel quality (e.g., wideband CQI) corresponding to a first channel quality measured in the corresponding time slot, and a plurality of second measured channel quality (e.g., subband CQI) corresponding to a second channel quality measured on a subband spanning one time slot in the time slot set.

[0185] In some examples, the reporting component 810 may send a CSI report that includes the channel quality of two or more time slots from the time slot set during uplink transmission timing.

[0187] In some examples, the reporting component 810 may include in the CSI report a first measurement channel quality for each time slot in the time slot set, and a second measurement channel quality set for each time slot in the time slot set, wherein each second measurement channel quality of the corresponding time slot is indicated by an incremental value relative to the first measurement channel quality of the corresponding time slot.

[0188] In some examples, the reporting component 810 may include in the CSI report a first measurement channel quality of a first time slot in the time slot set, a first measurement channel quality of an additional time slot in the time slot set, and a second measurement channel quality set for each time slot in the time slot set, wherein each of the first measurement channel quality of the additional time slots and each of the second measurement channel quality set is indicated by an incremental value relative to the first measurement channel quality of the first time slot.

[0189] In some examples, the reporting component 810 may include in the CSI report a first measurement channel quality of a first time slot of a time slot set, a first measurement channel quality of an additional time slot of the time slot set, a second measurement channel quality set of the first time slot, and a second measurement channel quality set of the additional time slot, wherein each of the second measurement channel quality set of the first time slot is indicated by an increment value relative to the first measurement channel quality of the first time slot, and wherein each of the first measurement channel quality of the additional time slot and the second measurement channel quality set of the additional time slot is indicated by an increment value relative to the corresponding first measurement channel quality or second measurement channel quality of the first time slot.

[0190] RS Resource Component 815 can receive one or more CSI-RS resources associated with a CSI report.

[0191] In some examples, the receiver indicates a configuration that one or more CSI-RS resources are transmitted via repetition, wherein the repetition transmission includes one or more CSI-RS resources being transmitted using the same spatial transmission filter.

[0193] In some cases, the method also includes receiving a multi-stage transmission for each of one or more CSI-RS resources on a second set of time slots that at least partially overlaps with the time slot set, wherein each stage of the multi-stage transmission is transmitted in a time slot of the time slot set.

[0194] In some cases, one or more CSI-RS resources are periodic or semi-persistent CSI-RS resources.

[0195] In some cases, the method further includes receiving, at each transmission timing for each of the periodic or semi-persistent CSI-RS resources, a multi-stage transmission for each of the one or more CSI-RS resources on a second time slot set that at least partially overlaps with the time slot set, wherein each stage of the multi-stage transmission is transmitted in a time slot of the second time slot set.

[0196] In some cases, each of one or more CSI-RS resources is transmitted in a time slot of a second time slot set that at least partially overlaps with the time slot set.

[0197] The channel quality component 820 can determine the channel quality of each time slot in the time slot set based on one or more CSI-RS measurements.

[0198] In some examples, the channel quality component 820 can measure the first channel quality associated with the frequency range of the time slot set for each time slot in the time slot set.

[0201] In some examples, the channel quality component 820 can generate each of the second set of measured channel quality based on the same CRI, the same PMI, and the same RI.

[0202] In some examples, determining the channel quality of each slot in a set of slots involves determining the channel quality in a CSI reference resource that includes multiple slots.

[0203] In some examples, the CQI for each of multiple time slots of a CSI reference resource is determined, assuming that each of the multiple time slots has the same time slot format, wherein the time slot format includes at least one or more of the following: the number of OFDM symbols for the Physical Downlink Control Channel (PDCCH); the number of OFDM symbols for PDSCH symbols and DMRS symbols; the frequency bandwidth configured for CQI calculation; the ratio of PDSCH energy (EPRE) per resource element to CSI-RS EPRE; the number of DMRS symbols; the assumption that the PDSCH symbols do not include DMRS; the PRB bundle size for DMRS symbols and PDSCH symbols equal to two Physical Resource Blocks (PRBs); and PMI.

[0204] In some examples, the channel quality component 820 can avoid determining channel quality during identified invalid time slots.

[0205] In some examples, the channel quality component 820 can measure the channel quality of the identified valid time slots.

[0206] In some examples, determining the channel quality of each slot in the second time slot set includes determining the multi-slot CQI on the second time slot set, wherein determining the multi-slot CQI includes determining the CQI of each slot in the second time slot set.

[0207] In some cases, CSI reporting configurations include multi-slot CQI configurations.

[0208] The time slot component 825 can determine the number of time slots included in the CSI reference resource and the time slot interval associated with that number of time slots based on one or more predetermined values ​​or based on the configuration sent by the base station via RRC messages or MAC-CE.

[0209] In some examples, the time slot component 825 can determine the time slot set based on the number of time slots and the time slot interval.

[0210] In some examples, the number of time slots between the last time slot and the uplink time slot of the CSI reference resource is determined based on the report type associated with the CSI report, where the report type includes periodic reports, semi-persistent reports, or non-periodic reports.

[0211] In some examples, the slot component 825 can identify invalid slots used for CQI calculations from a CSI reference resource that includes multiple slots.

[0214] In some cases, the time slot interval is equal to the number of zero time slots between a time slot in the time slot set and another time slot in the time slot set.

[0215] In some cases, the time slot interval is equal to the number of one or more time slots between a time slot in the time slot set and another time slot in the time slot set.

[0216] In some cases, the number of stages and the time slot interval of a multi-stage transmission are configured by the network via RRC messages or MAC-CE.

[0218] Figure 9A schematic diagram of a system 900 including device 905 supporting multi-slot CQI reporting according to various aspects of this disclosure is shown. Device 905 may be an example of device 605, device 705, or UE 115 as described herein, or a component including device 805, device 905, or UE 115.

These components may communicate electronically via one or more buses (e.g., bus 945).

[0219] The communication manager 910 can identify CSI report configuration or trigger for reporting CSI reports, send CSI reports including channel quality of two or more time slots in the time slot set during uplink transmission opportunities, receive one or more CSI-RS resources associated with the CSI report, and determine the channel quality of each time slot in the time slot set based on measurements of one or more CSI-RS resources.

[0220] The I / O controller 915 can manage the input and output signals of the device 905. The I / O controller 915 can also manage peripheral devices not integrated into the device 905. In some cases, the I / O controller 915 can represent a physical connection or port to an external peripheral device. In other cases, the I / O controller 915 can utilize an operating system, such as... Or another well-known operating system. In other cases, the I / O controller 915 may represent or interact with a modem, keyboard, mouse, touchscreen, or similar device. In some cases, the I / O controller 915 may be implemented as part of a processor. In some cases, a user may interact with the device 905 via the I / O controller 915 or via hardware components controlled by the I / O controller 915.

In some cases, processor 940 may be configured to operate a memory array using a memory controller. In other cases, the memory controller may be integrated into processor 940. Processor 940 may be configured to execute computer-readable instructions stored in memory (e.g., memory 930) to cause device 905 to perform various functions (e.g., functions or tasks supporting multi-slot CQI reporting).

[0225] Code 935 may include instructions for implementing various aspects of this disclosure, including instructions for supporting wireless communication. Code 935 may be stored in a non-transitory computer-readable medium such as system memory or other types of memory.

Device 1005 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0227] Receiver 1010 can receive information associated with various information channels (e.g., control channels, data channels, and information related to multi-slot CQI reporting), such as packets, user data, or control information. This information can be transmitted to other components of device 1005. Receiver 1010 can serve as a reference. Figure 13 Examples of various aspects of the transceiver 1320 described herein.
