[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 093,098, filed October 16, 2020, entitled “DIFFERENTIATED CHANNEL STATEINFORMATION FEEDBACK BASED ON DECODING STATISTICS,” and U.S. Non-Provisional Patent Application No. 17 / 450,875, filed October 14, 2021, entitled “DIFFERENTIATED CHANNEL STATEINFORMATION FEEDBACK BASED ON DECODING STATISTICS,” the contents of which are expressly incorporated herein by reference. Technical Field

[0003] In general, aspects of this disclosure relate to wireless communication, and more specifically, aspects of this disclosure relate to techniques and apparatus for feedback of differentiated channel state information based on decoding statistics. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / Improved LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs may communicate with the BS via downlink and uplink. "Downlink" or "forward link" refers to the communication link from the BS to the UE, and "uplink" or "backlink" refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, or 5G Node B.

[0006] The multiple access technologies described above have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), thereby better supporting mobile broadband internet access, as well as beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. However, with the continued growth in demand for mobile broadband access, there is a need for further improvements to LTE, NR, and other radio access technologies. Summary of the Invention

[0032] User equipment (UE) can receive downlink communications on the Physical Downlink Shared Channel (PDSCH). The UE may successfully decode downlink communications or fail to decode them. In some examples, the UE can provide PDSCH decoding statistics so that the base station can adjust modulation and coding schemes, resource allocation, and / or transmit power for retransmissions of downlink communications or for new downlink communications. PDSCH decoding statistics can be sent as Channel State Information (CSI) feedback (e.g., in CSI feedback). However, CSI feedback based on PDSCH decoding statistics may not be sent in a timely or efficient manner. Statistics for unsuccessful decoding may be received too late to help future retransmissions or other communications succeed, and unsuccessful communications result in wasted power, processing resources, and signaling resources for the UE. In contrast, while PDSCH decoding statistics for successful downlink communications can help the base station adjust transmissions, statistics for successful communications do not have the same urgency associated with unsuccessful communications.

[0033] Based on the aspects described herein, the UE can provide PDSCH decoding information (e.g., statistics) in the CSI feedback for unsuccessful decoding of downlink communications in a different manner than for successful decoding. For example, due to the urgency of failed communications, the UE can provide PDSCH decoding statistics for unsuccessful decoding in physical uplink resources that appeared earlier than the physical uplink resources used for successful decoding. In some aspects, the UE can aggregate PDSCH decoding statistics for multiple successfully decoded communications. In this way, the UE can provide PDSCH decoding statistics for transmission adjustments quickly and efficiently. As a result, the UE saves power, processing resources, and signaling resources that would otherwise be consumed by other failed decoding attempts.

[0034] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will recognize that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0035] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings, through various frames, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0036] It should be noted that while this document may use terms commonly associated with 5G or NR radio access technology (RAT) to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0037] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. Wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, or Transmit / Receive Point (TRP). Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0038] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the examples shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0039] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0040] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, or repeater.

[0041] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) such as macro BSs, pico BSs, femto BSs, and / or relay BSs. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0042] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0043] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet device, camera, gaming device, netbook, smartbook, ultrabook, medical device or apparatus, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music or video device, or satellite radio unit, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0044] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing housing the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0045] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology and / or air interface. A frequency can also be referred to as a carrier and / or channel. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0046] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.) and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0047] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) (spanning from 410 MHz to 7.125 GHz), and / or can communicate using an operating band with a second frequency range (FR2) (spanning from 24.25 GHz to 52.6 GHz). The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequencies (IFs). Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "below 6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise explicitly stated, it should be understood that the terms "below 6 GHz" and the like (if used herein) can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or intermediate frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the terms "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequencies (e.g., below 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0048] As pointed out above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0049] Figure 2 This is a diagram illustrating an example of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally, T ≥ 1 and R ≥ 1.

[0050] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., code and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, permission, upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can (e.g., for OFDM) process its corresponding output symbol stream to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t respectively.

[0051] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and / or CQI, etc. In some aspects, one or more components of the UE 120 may be included in the housing.

[0052] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0053] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within the following: one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components).

[0054] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-coded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264 and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 6-15 (Described).

[0055] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 6-15 (Described).

[0056] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other components may perform one or more techniques associated with differential CSI feedback based on decoding statistics, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 12 Process 1200 Figure 13 The operation of process 1300 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 12 Process 1200 Figure 13 The operation of process 1300 and / or other processes as described herein. In some aspects, the execution instructions may include run instructions, translation instructions, compilation instructions, and / or interpretation instructions, etc.

[0057] In some aspects, UE 120 includes: a unit for determining whether communication on the PDSCH has been successfully decoded or not; and / or a unit for transmitting CSI feedback including PDSCH decoding information via a first operation based at least in part on the determination that the communication has been successfully decoded, or via a second operation based at least in part on the determination that the communication has not been successfully decoded. The units used by UE 120 to perform the operations described herein may include, for example, an antenna 252, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a modulator 254, a controller / processor 280, and / or a memory 282.

[0058] In some aspects, base station 110 includes: a unit for receiving CSI feedback for a first communication on PDSCH, including PDSCH decoding information, from a UE via a first operation or a second operation, the first operation corresponding to successful decoding of the first communication on PDSCH, and the second operation corresponding to unsuccessful decoding of the first communication on PDSCH; and / or a unit for scheduling a second communication on PDSCH for the UE based at least in part on the PDSCH decoding information. The units used by base station 110 to perform the operations described herein may include, for example, a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, and / or a scheduler 246.

[0059] In some aspects, base station 110 includes: a unit for transmitting uplink permission in physical downlink resources, the uplink permission scheduling PUSCH resources for receiving CSI feedback for a plurality of successfully decoded communications on the PDSCH including decoding information, wherein receiving CSI feedback for the plurality of communications via a first operation includes: receiving CSI feedback in the scheduled PUSCH resources.

[0060] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to the boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be performed by the controller / processor 280 or under the control of the controller / processor 280.

[0061] As pointed out above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0062] Figure 3 This is a diagram illustrating example 300 of physical channels and reference signals in a wireless network according to this disclosure. Figure 3 As shown, the downlink channel and downlink reference signal can carry information from base station 110 to UE 120, and the uplink channel and uplink reference signal can carry information from UE 120 to base station 110.

[0063] As shown in the figure, downlink channels may include a Physical Downlink Control Channel (PDCCH) carrying downlink control information (DCI), a Physical Downlink Control Channel (PDSCH) carrying downlink data, or a Physical Broadcast Channel (PBCH) carrying system information, etc. In some aspects, PDSCH communication may be scheduled by PDCCH communication. As further shown, uplink channels may include a Physical Uplink Control Channel (PUCCH) carrying uplink control information (UCI), a Physical Uplink Shared Channel (PUSCH) carrying uplink data, or a Physical Random Access Channel (PRACH) for initial network access, etc. In some aspects, UE 120 may send acknowledgment (ACK) or negative acknowledgment (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in the UCI on the PUCCH and / or PUSCH.

[0064] As further illustrated, downlink reference signals may include a synchronization signal block (SSB), a CSI reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), or a phase tracking reference signal (PTRS), etc. As also illustrated, uplink reference signals may include a sounding reference signal (SRS), a DMRS, or a PTRS, etc.

[0065] SSBs can carry information for initial network acquisition and synchronization, such as the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH, and PBCH DMRS. SSBs are sometimes referred to as synchronization signal / PBCH (SS / PBCH) blocks. In some aspects, base station 110 can transmit multiple SSBs on multiple corresponding beams, and SSBs can be used for beam selection.

[0066] The CSI-RS can carry information for downlink channel estimation (e.g., downlink CSI acquisition), which can be used for scheduling, link adaptation, or beam management, etc. Base station 110 can configure a CSI-RS set for UE 120, and UE 120 can measure the configured CSI-RS set. Based at least in part on the measurement, UE 120 can perform channel estimation and report channel estimation parameters to base station 110 (e.g., in the CSI report), such as CQI, precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), layer indicator (LI), rank indicator (RI), or reference signal received power (RSRP), etc. Base station 110 can use the CSI report to select transmission parameters for downlink communication to UE 120, such as the number of transport layers (e.g., rank), precoding matrix (e.g., precoder), modulation and coding scheme (MCS), or refined downlink beam (e.g., using a beam refinement process or beam management process), etc.

[0067] DMRS can carry information used to estimate radio channels for demodulating associated physical channels (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of DMRS can be specific to the physical channels it is used to estimate. DMRS is UE-specific, can be beamformed, can be confined to scheduled resources (e.g., not transmitted over broadband), and can be transmitted only when necessary. As shown, DMRS is used for both downlink and uplink communication.

[0068] PTRS can carry information for compensating oscillator phase noise. Typically, phase noise increases with the oscillator carrier frequency. Therefore, PTRS can be used to mitigate phase noise at high carrier frequencies (e.g., millimeter-wave frequencies). PTRS can be used to track the phase of a local oscillator and achieve suppression of phase noise and common phase error (CPE). As shown, PTRS is used for both downlink communication (e.g., on PDSCH) and uplink communication (e.g., on PUSCH).

[0069] The PRS can carry information for performing timing or ranging measurements on the UE 120 based on signals transmitted by base station 110 to improve observed time difference of arrival (OTDOA) positioning performance. For example, the PRS can be a pseudo-random quadrature phase shift keying (QPSK) sequence mapped onto a diagonal pattern with frequency and time shifts to avoid conflicts with cell-specific reference signals and control channels (e.g., PDCCH). Typically, the PRS can be designed to improve the detectability of the UE 120, which may need to detect downlink signals from multiple neighboring base stations to perform OTDOA-based positioning. Therefore, the UE 120 can receive PRS from multiple cells (e.g., a reference cell and one or more neighboring cells) and can report the reference signal time difference (RSTD) based on the OTDOA measurements associated with the PRS received from the multiple cells. In some aspects, base station 110 can then calculate the location of the UE 120 based on the RSTD measurements reported by the UE 120.

[0070] The SRS can carry information for uplink channel estimation, which can be used for scheduling, link adaptation, precoder selection, or beam management. Base station 110 can configure one or more SRS resource sets for UE 120, and UE 120 can transmit SRS on the configured SRS resource sets. The SRS resource sets can have configured uses, such as uplink CSI acquisition, downlink CSI acquisition for reciprocal operation, uplink beam management, etc. Base station 110 can measure the SRS, can perform channel estimation at least partially based on the measurement, and can use the SRS measurement to configure communication with UE 120.

[0071] As pointed out above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0072] Figure 4 This is a diagram illustrating example 400 of providing PDSCH decoding in CSI feedback according to this disclosure.

[0073] The UE can receive downlink communication on the PDSCH. As shown in Example 400, downlink communication on the PDSCH can be scheduled by downlink permission. Downlink permission can be received in the DCI. The UE can successfully decode downlink communication and can provide ACK in the PUCCH resource used for HARQ feedback. If the UE fails to decode downlink communication, the UE can provide NACK in the HARQ feedback PUCCH resource. In some examples, the UE can provide PDSCH decoding statistics, as shown in Example 400, allowing the base station to adjust the MCS, resource allocation, and / or transmit power for downlink communication retransmissions or new downlink communication. PDSCH decoding statistics can be sent in the CSI feedback.

[0074] As pointed out above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0075] Figure 5 This is a diagram illustrating example 500 of the effective SNR and outer loop SNR according to this disclosure.

[0076] While the UE can send PDSCH decoding statistics in the CSI feedback, it may not do so in a timely or efficient manner. Statistics for unsuccessful decoding may be received too late to help with future retransmissions, and unsuccessful communications result in wasted power, processing, and signaling resources for the UE. In contrast, while PDSCH decoding statistics for successful downlink communications can help the base station adjust transmissions, statistics for successful communications do not have the same urgency associated with unsuccessful communications.

[0077] Example 500 illustrates an example of the difference in urgency between successful decoding (e.g., ACK) and unsuccessful decoding (e.g., NACK). The outer loop SNR 520 can be part of a feedback loop associated with the effective SNR 510. The outer loop can be applied to MCS selection. For NACK, CQI can be fed back immediately to adjust the SNR, because the outer loop SNR based solely on HARQ-ACK may not provide the information needed for fast and effective transmission adjustment. For ACK, CQI may be delayed, because the outer loop SNR based solely on HARQ-ACK feedback may be sufficient for adjustment. Example 500 shows a graph based on the following formula:

[0078] SNR(i)=SNR CQI +Δ offset (i)

[0079] Where Δ offset (i)=min{Δoffset (i-1)+δ·1 ACK -9δ·1 NACK ,offset max}

[0080] Δ offset It is cumulative, and δ is the step size. Note that for each NACK, there is a significant drop in the outer loop SNR of 520 to 530.

[0081] Based on the aspects described herein, the UE can provide PDSCH decoding information (e.g., statistics) in the CSI feedback for unsuccessful decoding in a different manner than for successful decoding. For example, due to the urgency of failed communications, the UE can provide PDSCH decoding statistics for unsuccessful decoding in physical uplink resources that appear earlier than the physical uplink resources used for successful decoding. In some aspects, the UE can also aggregate PDSCH decoding statistics for multiple successfully decoded communications. In this way, the UE can provide PDSCH decoding statistics for transmission adjustments quickly and efficiently. As a result, the UE saves power, processing resources, and signaling resources that would otherwise be consumed by other failed decoding attempts.

[0082] As pointed out above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 The example described.

[0083] Figure 6 This is a diagram illustrating example 600 of differentiated CSI feedback for PDSCH decoding statistics according to this disclosure. Figure 6 The diagram illustrates BS 610s that can communicate with each other on either the downlink or uplink (e.g., Figure 1 and 2 The BS110 and UE 620 (as depicted in the text) Figure 1 and 2 UE 120 as depicted in the text.

[0084] As shown by reference numeral 630 in the attached figure, UE 620 can determine whether downlink communication on the PDSCH was successfully decoded or not. UE 620 can determine to send an ACK for successful decoding and a NACK for unsuccessful decoding. UE 620 can determine PDSCH decoding information associated with decoding the downlink communication. PDSCH decoding information may include PDSCH decoding statistics, such as bit error rate, decoding signal-to-noise ratio (SNR), log-likelihood ratio (LLR), and / or RSRP. In some aspects, the UE may reuse CQI or PMI for PDSCH decoding statistics. PDSCH decoding information may include a CQI representing one or more parameters of PDSCH decoding. PDSCH decoding information may also include a PMI representing one or more measurements of DMRS in the communication.

[0085] UE 620 may transmit PDSCH decoding information in one or more fields periodically used for CSI feedback. As shown by reference numeral 635, UE 620 may transmit CSI feedback including PDSCH decoding information via a first operation based at least in part on a determination that communication was successfully decoded, or via a second operation based at least in part on a determination that communication was not successfully decoded. Compared to the first operation, the duration between receiving communication and transmitting CSI feedback in the second operation can be shorter. For example, for successful decoding, UE 620 may transmit CSI feedback at a different time and / or on different resources than for unsuccessful decoding. As another example, if the CSI feedback including PDSCH decoding information is sent at least in part based on a determination that the communication has been successfully decoded, a first duration may exist between the reception of the communication and the transmission of the CSI feedback including PDSCH decoding information; and if the CSI feedback including PDSCH decoding information is sent at least in part based on a determination that the communication has not been successfully decoded, a second duration may exist between the reception of the communication and the transmission of the CSI feedback including PDSCH decoding information, wherein the second duration may be less than (e.g., shorter than) the first duration. The first operation may involve transmitting the CSI feedback in a first physical uplink resource, and the second operation may involve transmitting the CSI feedback in a second physical uplink resource, wherein the second physical uplink resource appears earlier than the first physical uplink resource. The following is in conjunction with... Figures 7-11 Examples of different operations for the differentiated transmission of CSI feedback are described.

[0086] As shown by reference numeral 640 in the attached figure, BS 610 can receive CSI feedback and adjust transmissions based at least in part on PDSCH decoding statistics indicated by the CSI feedback. For example, BS 610 can schedule communication on the PDSCH for UE 620 based at least in part on the PDSCH decoding information. This communication can be a retransmission or a new communication. As shown by reference numeral 650 in the attached figure, BS 610 can send this communication.

[0087] As pointed out above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 The example described.

[0088] Figure 7 This is a diagram illustrating example 700 of differentiated CSI feedback for PDSCH decoding statistics according to this disclosure.

[0089] In some aspects, the UE may send CSI feedback that includes PDSCH decoding statistics for successful decoding on a different timeline than CSI feedback that includes statistics for PDSCH decoding that was unsuccessful. Example 700 shows a faster timeline (shorter delay) for CSI feedback in the case of PDSCH decoding failure (e.g., NACK). Example 700 shows a slower timeline (longer delay) for CSI feedback in the case of PDSCH decoding success (e.g., ACK).

[0090] As pointed out above, Figure 7 This is provided as an example. Other examples may differ from the one provided. Figure 7 The example described.

[0091] Figure 8 This is a diagram illustrating example 800 of differentiated CSI feedback for PDSCH decoding statistics according to this disclosure.

[0092] In some aspects, the UE may send CSI feedback that includes PDSCH decoding statistics for successful decoding of communication on a different resource than for CSI feedback for unsuccessful decoding. Example 800 shows that if PDSCH decoding for communication fails, the UE may send CSI feedback on the same PUCCH resource as the one carrying HARQ-ACK feedback (e.g., NACK). The delay from communication to the PUCCH resource with NACK and CSI feedback may include the delay indicated by fields in the DCI that schedules the communication (e.g., conventional K1 delay).

[0093] If the PDSCH decoding passes (e.g., ACK), the UE can send CSI feedback for PDSCH decoding statistics in a different PUCCH resource than the one used for HARQ-ACK feedback. In some aspects, the UE can send CSI feedback in the PUSCH resource.

[0094] As pointed out above, Figure 8 This is provided as an example. Other examples may differ from the one provided. Figure 8 The example described.

[0095] Figure 9 This is a diagram illustrating example 900 of differentiated CSI feedback for PDSCH decoding statistics according to this disclosure.

[0096] In some aspects, the UE can send CSI feedback that includes PDSCH decoding statistics for successful decoding of a communication, with a different granularity compared to CSI feedback for unsuccessful decoding. Example 900 shows that if PDSCH decoding fails, the UE can send CSI feedback for a single communication in a PUCCH resource. The PUCCH resource can be a HARQ feedback PUCCH resource. If PDSCH decoding succeeds, the UE can send CSI feedback for PDSCH decoding of multiple successfully decoded communications. In some aspects, the UE can aggregate multiple CSI reports for multiple successfully decoded communications (e.g., a corresponding CSI report for a given communication) in a single PUCCH resource or a single PUSCH resource. In some aspects, the UE can concatenate multiple CSI reports. In some aspects, the UE can aggregate CSI feedback for multiple communications into a single CSI report.

[0097] As pointed out above, Figure 9 This is provided as an example. Other examples may differ from the one provided. Figure 9 The example described.

[0098] Figure 10 This is a diagram illustrating example 1000 of differentiated CSI feedback for PDSCH decoding statistics according to this disclosure.

[0099] In some aspects, the UE can be configured with periodic resource allocations for transmissions. Example 1000 illustrates periodic PUCCH resources. The UE can aggregate one or more CSI reports of PDSCH decoding statistics for successfully decoded communications into one of these periodic PUCCH resources, 1002. In contrast, the UE can include CSI feedback for undecoded communications in the HARQ feedback PUCCH resource 1004.

[0100] As pointed out above, Figure 10 This is provided as an example. Other examples may differ from the one provided. Figure 10 The example described.

[0101] Figure 11 This is a diagram illustrating example 1100 of differentiated CSI feedback for PDSCH decoding statistics according to this disclosure.

[0102] The base station can send a configured permission (CG) configuration to the UE. For example, the base station can send configuration information in a Radio Resource Configuration (RRC) message or in a DCI identifying the CG. In some aspects, the configuration information identifying the CG can indicate resource allocations (e.g., in the time domain, frequency domain, spatial domain, and code domain) specifically for the UE to transmit uplink communications. The CG can identify resources or sets of resources that the UE can use to transmit uplink communications (e.g., data, control information). For example, the CG configuration can identify resource locations for the PUSCH.

[0103] In some aspects, as shown in Example 1100, the base station can use uplink permission to trigger the UE to report an aggregated report of PDSCH decoding statistics in the CSI feedback for a certain number N (e.g., 3) of successfully decoded communications. This report can be an aggregated report comprising a concatenation of multiple reports based on multiple successfully decoded communications. Alternatively, the report can comprise a single CSI report for multiple communications. As shown in Example 1100, the UE can send the report in PUSCH resource 1102 scheduled by uplink permission on the PDCCH.

[0104] In contrast, the UE can send a PDSCH decoding statistics report in the CSI feedback for unsuccessfully decoded communications in HARQ PUCCH resource 1104, which may appear earlier than the scheduled PUSCH resource used for CSI feedback for successful communications. This allows the base station to obtain PDSCH decoding statistics promptly and efficiently based on whether PDSCH decoding was successful.

[0105] As pointed out above, Figure 11 This is provided as an example. Other examples may differ from the one provided. Figure 11 The example described.

[0106] Figure 12 This is a diagram illustrating, for example, an example process 1200 performed by a UE, according to this disclosure. Example process 1200 is where the UE (e.g., Figures 1-3 The UE 120 depicted in the text Figure 6 The example depicted in UE 620 is an instance of performing operations associated with differentiated CSI feedback based on decoding statistics.

[0107] like Figure 12 As shown, in some aspects, process 1200 may include: determining whether communication on the PDSCH has been successfully decoded (block 1210). For example, the UE (e.g., using...) Figure 14 The determining component 1408 described herein can determine whether communication on the PDSCH has been successfully decoded, as described above. This may include determining whether communication on the PDSCH has been successfully decoded or not.

[0108] like Figure 12 Additionally, as shown, in some aspects, process 1200 may include: transmitting CSI feedback (block 1220) including PDSCH decoding information via a first operation, at least in part based on a determination that the communication was successfully decoded, or via a second operation, at least in part based on a determination that the communication was not successfully decoded. For example, the UE (e.g., using...) Figure 14 The transmitting component 1404 described herein may transmit CSI feedback, including PDSCH decoding information, via a first operation based at least in part on a determination that the communication has been successfully decoded, or via a second operation based at least in part on a determination that the communication has not been successfully decoded, as described above.

[0109] Process 1200 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0110] In a first aspect, the duration between receiving the communication and sending the CSI feedback in the second operation is shorter than the duration between receiving the communication and sending the CSI feedback in the first operation. In some aspects, the duration between receiving the communication and sending the CSI feedback in the second operation is shorter than that in the first operation. In some aspects, if the CSI feedback including PDSCH decoding information is sent via the first operation, there is a first duration between receiving the communication and sending the CSI feedback. If the CSI feedback including PDSCH decoding information is sent via the second operation, there is a second duration between receiving the communication and sending the CSI feedback. The second duration is shorter than the first duration.

[0111] In some aspects, the first physical uplink resource for CSI feedback used in the first operation is different from the physical uplink resource for CSI feedback used in the second operation. In a second aspect, either alone or in combination with the first aspect, the physical uplink resource for CSI feedback used in the first operation appears after the physical uplink resource for CSI feedback used in the second operation. In some aspects, the first physical uplink resource is used if the CSI feedback is sent via the first operation; and the second physical uplink resource is used if the CSI feedback is sent via the second operation. The first physical uplink resource appears after the second physical uplink resource.

[0112] In a third aspect, either alone or in combination with one or more of the first and second aspects, the physical uplink resource used for the first operation is a HARQ feedback PUCCH resource that appears after the HARQ feedback PUCCH resource used for the second operation, or a PUSCH resource that appears after the HARQ feedback PUCCH resource used for the second operation. That is, if the CSI feedback is sent via the first operation, the first physical uplink resource is used; and if the CSI feedback is sent via the second operation, the second physical uplink resource is used, and the first physical uplink resource appears after the second physical uplink resource. In some aspects, the first physical uplink resource is either a HARQ feedback PUCCH resource or a PUSCH resource, and the second physical uplink resource is a HARQ feedback PUCCH resource.

[0113] In the fourth aspect, either alone or in combination with one or more of the first to third aspects, the delay between the communication and the HARQ feedback PUCCH resource for the second operation is indicated by a field in the DCI that schedules the communication, or is at least partially indicated based on the K1 duration.

[0114] In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the physical uplink resource for the second operation is a HARQ feedback PUCCH resource, and the physical uplink resource for the first operation is a physical uplink resource that appears after the physical uplink resource for the second operation, comprising PDSCH decoding information for multiple communications that have been successfully decoded on the PDSCH. That is, in some aspects, the first physical uplink resource comprises PDSCH decoding information for multiple communications that have been successfully decoded on the PDSCH, and the second physical uplink resource is a Hybrid Automatic Repeat Request (HARQ) Feedback Physical Uplink Control Channel (PUCCH) resource. The first physical uplink resource appears after the second physical uplink resource.

[0115] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the CSI feedback for the first operation includes PDSCH decoding information for a plurality of communications that have been successfully decoded on the PDSCH, wherein the plurality of communications includes the communications.

[0116] In the seventh aspect, either alone or in combination with one or more of the first to sixth aspects, the CSI feedback for the first operation includes a corresponding PDSCH decoding information report for each of the plurality of communications.

[0117] In the eighth aspect, either alone or in combination with one or more of the first to seventh aspects, the CSI feedback for the first operation includes a single PDSCH decoding information report for the plurality of communications.

[0118] In the ninth aspect, sending the CSI feedback for the plurality of communications via the first operation, either alone or in combination with one or more of the first to eighth aspects, includes sending the CSI feedback in a periodic PUCCH resource.

[0119] In the tenth aspect, sending the CSI feedback for the plurality of communications via the first operation, either alone or in combination with one or more of the first to ninth aspects, includes sending the CSI feedback in a PUSCH resource that is allowed to be scheduled by uplink in physical downlink resources.

[0120] In the eleventh aspect, either alone or in combination with one or more of the first to tenth aspects, the uplink is permitted to be dedicated to PDSCH decoding information transmitted in the CSI feedback.

[0121] In the twelfth aspect, either alone or in combination with one or more of the first to eleventh aspects, the uplink permission indicates the number of PDSCH decoding reports that will be aggregated in the PUSCH resources scheduled by the uplink permission for successfully decoded communications on the PDSCH.

[0122] In the thirteenth aspect, alone or in combination with one or more of the first to twelfth aspects, the PDSCH decoding information includes one or more of the following: bit error rate, decoding LLR, SNR, CQI representing PDSCH decoding statistics, PMI representing PDSCH decoding statistics, or RSRP.

[0123] Although Figure 12 An example box of process 1200 is shown, but in some aspects, process 1200 may include... Figure 12 The boxes shown are those that are additional, fewer, different, or arranged differently. Alternatively, two or more boxes in process 1200 can be executed in parallel.

[0124] Figure 13 This is a diagram illustrating, for example, an example process 1300 performed by a base station, according to this disclosure. Example process 1300 is where a base station (e.g., Figures 1-3 Base station 110 depicted in the text Figure 6 The example described in BS 610 is an example of performing operations associated with differentiated CSI feedback based on decoding statistics.

[0125] like Figure 13 As shown, in some aspects, process 1300 may include: receiving from the UE via a first operation or a second operation a CSI feedback for a first communication on the PDSCH, including PDSCH decoding information, the first operation corresponding to successful decoding of the first communication on the PDSCH, and the second operation corresponding to unsuccessful decoding of the first communication on the PDSCH (block 1310). For example, a base station (e.g., using...) Figure 15 The receiving component 1502 described herein can receive CSI feedback for a first communication on the PDSCH, including PDSCH decoding information, from the UE via a first operation or a second operation, the first operation corresponding to successful decoding of the first communication on the PDSCH, and the second operation corresponding to unsuccessful decoding of the first communication on the PDSCH, as described above.

[0126] like Figure 13 Additionally, as shown, in some aspects, process 1300 may include: scheduling a second communication on the PDSCH for the UE based at least in part on the PDSCH decoding information (block 1320). For example, a base station (e.g., using...) Figure 15The scheduling component 1508 described herein can schedule a second communication on the PDSCH for the UE based at least in part on the PDSCH decoding information, as described above.

[0127] Process 1300 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0128] In a first aspect, the duration between sending the second communication and receiving the CSI feedback for the second operation is shorter than the duration between sending the second communication and receiving the CSI feedback for the first operation. In some aspects, the duration between sending the communication and receiving the CSI feedback for the second operation is shorter than that for the first operation. In some aspects, if the CSI feedback including PDSCH decoding information is received via the first operation, there is a first duration between sending the communication and receiving the CSI feedback. If the CSI feedback including PDSCH decoding information is received via the second operation, there is a second duration between sending the communication and receiving the CSI feedback. The second duration may be shorter than the first duration.

[0129] In some aspects, the first physical uplink resource for CSI feedback used in the first operation is different from the physical uplink resource for CSI feedback used in the second operation. In a second aspect, either alone or in combination with the first aspect, the physical uplink resource for CSI feedback used in the first operation appears after the physical uplink resource for CSI feedback used in the second operation. In some aspects, if the CSI feedback is received via the first operation, the first physical uplink resource is used; and if the CSI feedback is received via the second operation, the second physical uplink resource is used. The first physical uplink resource appears after the second physical uplink resource.

[0130] In a third aspect, either alone or in combination with one or more of the first and second aspects, the physical uplink resource used for the first operation is a HARQ feedback PUCCH resource that appears after the HARQ feedback PUCCH resource used for the second operation, or a PUSCH resource that appears after the HARQ feedback PUCCH resource used for the second operation. That is, if the CSI feedback is received via the first operation, the first physical uplink resource is used, and if the CSI feedback is received via the second operation, the second physical uplink resource is used, and the first physical uplink resource appears after the second physical uplink resource. In some aspects, the first physical uplink resource is either a HARQ feedback PUCCH resource or a PUSCH resource, and the second physical uplink resource is a HARQ feedback PUCCH resource.

[0131] In the fourth aspect, either alone or in combination with one or more of the first to third aspects, the delay between the second communication and the HARQ feedback PUCCH resource used for the second operation is indicated by a field in the DCI that schedules the second communication or at least in part based on the K1 duration.

[0132] In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the physical uplink resource for the second operation is a HARQ feedback PUCCH resource, and the physical uplink resource for the first operation is a physical uplink resource that appears after the physical uplink resource for the second operation, comprising PDSCH decoding information in the CSI feedback for multiple communications that have been successfully decoded on the PDSCH. That is, in some aspects, the first physical uplink resource includes PDSCH decoding information for multiple communications that have been successfully decoded on the PDSCH, and the second physical uplink resource is a HARQ feedback PUCCH resource.
