Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for selection or indication of channel state information (CSI) reporting parameters by a user equipment (UE). Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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 / LTE-Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include several base stations (BS) that can support communications for several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to a communication link from a BS to a UE, and an uplink (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, and the like.

[0006] The above-mentioned multiple access technologies have been used in various telecommunication standards to provide a common protocol that enables different user devices to communicate at a city, country, region, or even global level. New Radio (NR) (also referred to as 5G) is a collection of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies are still useful as the demand for mobile broadband access continues to increase. Summary of the invention

[0149] The various aspects of the present disclosure will be described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. Specifically, these aspects are provided to make the present disclosure detailed and complete, and to fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, regardless of whether these aspects are implemented independently of any other aspect of the present disclosure or in combination with any other aspect of the present disclosure. For example, any number of various aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the disclosure is intended to cover devices or methods practiced using other structures, functionality, or structures and functionality in addition to the various aspects of the disclosure set forth herein as additional to the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements in the claims.

[0150] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0151] It should be noted that while various aspects may be described using terminology typically associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0152] Figure 1 is a diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include several base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) 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, transmit receive point (TRP), and the like. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving this coverage area, depending on the context in which the term "cell" is used.

[0153] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0154] In some aspects, the cell may not necessarily be fixed, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the 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 through various types of backhaul interfaces such as direct physical connections or virtual networks using any suitable transport network.

[0155] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0156] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0157] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other (eg, directly or indirectly) via a wireless or wired backhaul.

[0158] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. UEs may be cellular phones (e.g., smart phones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablets, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices or equipment, biometric sensors / devices, wearable devices (smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), entertainment devices (e.g., music or video devices, or satellite radios), vehicle-mounted components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, or any other suitable device configured to communicate via wireless or wired media.

[0159] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs 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. A wireless node may provide connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (Customer Premises Equipment, CPE). UE 120 may be included in a housing that houses components (such as processor components and / or memory components) of UE 120. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0160] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0161] In certain aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary for communicating with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol or vehicle-to-infrastructure (V2I) protocol), and / or mesh network. 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.

[0162] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1) that can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2) that can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although portions of FR1 are greater than 6 GHz, FR1 is often referred to as a "below 6 GHz" frequency band. Similarly, FR2 is often referred to as a "millimeter wave" frequency band, although it is different from an extremely high frequency (EHF) frequency band (30 GHz–300 GHz) identified as a "millimeter wave" frequency band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that, if used herein, the term "below 6 GHz" or the like can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically noted, it should be understood that if used herein, the term "millimeter wave" or the like can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0163] As mentioned above, providing Figure 1 As an example. Other examples may differ from the Figure 1 Examples described.

[0164] Figure 2 is a diagram illustrating an example 200 of base station 110 and UE 120 communicating in wireless network 100 according to the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 254a through 254r, where in general T≥1 and R≥1.

[0165] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the (one or more) MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and up-convert) to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively.

[0166] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMOD) 254a to 254r, respectively. Each demodulator 254 may adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, among other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0167] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0168] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays or may be included in one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include sets of coplanar antenna elements and / or sets of non-coplanar antenna elements. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, sets of antenna elements, 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 of one or more components).

[0169] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by a TX MIMO processor 266, where applicable, further processed by demodulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 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.

[0170] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 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.

[0171] As described in greater detail elsewhere herein, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the UE 120 may perform one or more techniques associated with the UE's selection of CSI reporting parameters. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) may perform or direct e.g. Figure 6 The process of 600 Figure 7 The process 700 Figure 8 The process of 800 Fig. 9 900 and / or other processes described herein. Memories 242 and 282 may store data and program codes 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, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The process of 700 Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions.

[0172] In certain aspects, UE 120 may include: means for performing signal measurements; means for selecting a channel state information (CSI) reporting parameter from a plurality of CSI reporting parameters based at least in part on a result of performing the signal measurements, the plurality of CSI reporting parameters being included in a CSI reporting configuration configured for the UE; means for sending an indication of the selected CSI reporting parameter in uplink control information (UCI); and the like. In certain aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0173] In certain aspects, base station 110 may include: means for receiving UCI including an indication of a CSI reporting parameter selected by UE 120, wherein the selected CSI reporting parameter is one of a plurality of CSI reporting parameters included in a CSI reporting configuration configured on the UE; means for monitoring CSI reports from UE 120 based at least in part on the selected CSI reporting parameter; etc. In certain aspects, such means may include in conjunction with Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

In certain aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0175] In certain aspects, the base station 110 may include: means for sending configuration information indicating two or more CSI reporting settings for periodic CSI reporting; means for sending a signal indicating switching to a selected CSI reporting setting among the two or more CSI reporting settings; means for receiving a CSI report according to the selected CSI reporting setting; etc. In certain aspects, such means may include in conjunction with Figure 2 One or more components of the base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0176] As mentioned above, providing Figure 2 As an example. Other examples may differ from the Figure 2 Examples described.

[0177] Figure 3is a diagram illustrating an example beamforming architecture 300 supporting unicast coverage in a millimeter wave (mmW) channel according to the present disclosure. In certain aspects, the architecture 300 can implement aspects of the wireless network 100. In certain aspects, the architecture 300 can be implemented in a transmitting device (e.g., a first wireless communication device, UE, or base station) and / or a receiving device (e.g., a second wireless communication device, UE, or base station) as described herein.

[0178] In summary, Figure 3 300 is a diagram illustrating example hardware components of a wireless communication device according to certain aspects of the present disclosure. The components shown may include components that can be used for antenna element selection and / or beamforming for transmission of wireless signals. There are many architectures for antenna element selection and implementing phase shifting, only one example of which is shown here. Architecture 300 includes a modem (modulator / demodulator) 302, a digital-to-analog converter (DAC) 304, a first mixer 306, a second mixer 308, and a splitter 310. Architecture 300 also includes a plurality of first amplifiers 312, a plurality of phase shifters 314, a plurality of second amplifiers 316, and an antenna array 318 including a plurality of antenna elements 320.

[0179] Transmission lines or other waveguides, lines, traces, etc. are shown connecting various components to show how signals to be transmitted can travel between components. Reference numerals 322, 324, 326, and 328 indicate areas in the architecture 300 where different types of signals travel or are processed. Specifically, reference numeral 322 indicates an area where digital baseband signals travel or are processed, reference numeral 324 indicates an area where analog baseband signals travel or are processed, reference numeral 326 indicates an area where analog intermediate frequency (IF) signals travel or are processed, and reference numeral 328 indicates an area where analog radio frequency (RF) signals travel or are processed. The architecture also includes a local oscillator A 330, a local oscillator B 332, and a communication manager 334.

[0180] Each of the antenna elements 320 may include one or more sub-elements for radiating or receiving RF signals. For example, a single antenna element 320 may include a first sub-element that is cross-polarized with a second sub-element and can be used to independently transmit cross-polarized signals. The antenna element 320 may include a patch antenna, a dipole antenna, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between the antenna elements 320 may allow signals with desired wavelengths that are separately transmitted by the antenna elements 320 to interact or interfere (e.g., to form a desired beam). For example, given an expected range of wavelengths or frequencies, the spacing may provide a quarter wavelength, half a wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements 320 to allow signals within the expected range transmitted by the separated antenna elements 320 to interact or interfere.

[0181] The modem 302 processes and generates digital baseband signals, and may also control the operation of the DAC 304, the first and second mixers 306, 308, the splitter 310, the first amplifier 312, the phase shifter 314, and / or the second amplifier 316 to transmit signals via one or more or all of the antenna elements 320. The modem 302 may process signals and control operations according to a communication standard (such as the wireless standards discussed herein). The DAC 304 may convert the digital baseband signal received from the modem 302 (and to be transmitted) into an analog baseband signal. The first mixer 306 uses a local oscillator A 330 to up-convert the analog baseband signal into an analog IF signal within the IF. For example, the first mixer 306 may mix the signal with an oscillating signal generated by the local oscillator A 330 to "move" the baseband analog signal to the IF. In some cases, some processing or filtering (not shown) may occur at the IF. The second mixer 308 uses a local oscillator B 332 to up-convert the analog IF signal into an analog RF signal. Similar to the first mixer, the second mixer 308 can mix the signal with an oscillating signal generated by local oscillator B 332 to "move" the IF analog signal to the RF or frequency at which the signal is to be transmitted or received. The modem 302 and / or the communication manager 334 can adjust the frequency of local oscillator A 330 and / or local oscillator B 332 so that the desired IF and / or RF frequencies are generated and used to facilitate processing and transmission of signals within the desired bandwidth.

[0182] In the illustrated architecture 300, the signal up-converted by the second mixer 308 is split or copied into multiple signals by the splitter 310. The splitter 310 in the architecture 300 splits the RF signal into multiple identical or nearly identical RF signals. In other examples, any type of signal can be used for splitting, including using baseband digital, baseband analog or IF analog signals. Each of these signals can correspond to an antenna element 320, and the signal travels through amplifiers 312, 316, phase shifters 314 and / or other elements corresponding to the corresponding antenna element 320 and is processed by it to be provided to the corresponding antenna element 320 of the antenna array 318 and transmitted by it. In one example, the splitter 310 can be an active splitter connected to a power source and providing some gain, so that the RF signal leaving the splitter 310 is at a power level equal to or greater than the signal entering the splitter 310. In another example, the splitter 310 is a passive splitter that is not connected to a power source, and the RF signal exiting the splitter 310 may be at a lower power level than the RF signal entering the splitter 310 .

[0183] After being split by the splitter 310, the resulting RF signal can enter an amplifier (such as the first amplifier 312) or a phase shifter 314 corresponding to the antenna element 320. The first and second amplifiers 312, 316 are shown in dashed lines because one or both of them may not be necessary in some aspects. In some aspects, there are both the first amplifier 312 and the second amplifier 316. In some aspects, the first amplifier 312 and the second amplifier 316 do not exist. In some aspects, there is one of the two amplifiers 312, 316, but the other does not exist. As an example, if the splitter 310 is an active splitter, the first amplifier 312 may not be used. As another example, if the phase shifter 314 is an active phase shifter that can provide gain, the second amplifier 316 may not be used.

[0184] The amplifiers 312, 316 can provide a desired level of positive gain or negative gain. Positive gain (positive dB) can be used to increase the amplitude of the signal radiated by a particular antenna element 320. Negative gain (negative dB) can be used to reduce the amplitude and / or suppress the radiation of the signal by a particular antenna element. Each of the amplifiers 312, 316 can be independently controlled (e.g., by the modem 302 or the communication manager 334) to provide independent control of the gain for each antenna element 320. For example, the modem 302 and / or the communication manager 334 can have at least one control line connected to each of the splitter 310, the first amplifier 312, the phase shifter 314, and / or the second amplifier 316 that can be used to configure the gain to provide the desired amount of gain to each component and therefore to each antenna element 320.

[0185] The phase shifter 314 can provide a configurable phase shift or phase offset to the corresponding RF signal to be transmitted. The phase shifter 314 can be a passive phase shifter that is not directly connected to the power supply. The passive phase shifter may introduce some insertion loss. The second amplifier 316 can boost the signal to compensate for the insertion loss. The phase shifter 314 can be an active phase shifter connected to the power supply so that the active phase shifter provides a certain amount of gain or prevents insertion loss. The setting of each of the phase shifters 314 is independent, which means that each phase shifter can be set to provide a desired phase shift amount or the same phase shift amount or some other configuration. The modem 302 and / or the communication manager 334 can have at least one control line connected to each of the phase shifters 314, and it can be used to configure the phase shifter 314 to provide a desired phase shift amount or phase offset between the antenna elements 320.

[0186] In the illustrated architecture 300, the RF signal received by the antenna element 320 is provided to one or more of the first amplifiers 356 to boost the signal strength. The first amplifiers 356 can be connected to the same antenna array 318 (e.g., for time division duplex (TDD) operation). The first amplifiers 356 can be connected to different antenna arrays 318. The boosted RF signal is input to one or more of the phase shifters 354 to provide a configurable phase shift or phase offset for the corresponding received RF signal. The phase shifter 354 can be an active phase shifter or a passive phase shifter. The settings of the phase shifters 354 are independent, which means that each phase shifter can be set to provide a desired phase shift amount or the same phase shift amount or some other configuration. The modem 302 and / or the communication manager 334 can have at least one control line connected to each of the phase shifters 354, and it can be used to configure the phase shifter 354 to provide a desired phase shift amount or phase offset between the antenna elements 320.

[0187] The output of the phase shifter 354 can be input to one or more second amplifiers 352 to perform signal amplification of the received RF signal through the phase shift. The second amplifier 352 can be configured separately to provide a configured gain amount. The second amplifier 352 can be configured separately to provide a certain amount of gain to ensure that the signals input to the combiner 350 have the same amplitude. Amplifiers 352 and / or 356 are shown in dotted lines because they may not be necessary in some aspects. In some aspects, there are both amplifiers 352 and amplifiers 356. In another aspect, amplifiers 352 and amplifiers 356 do not exist. In other aspects, there is one of amplifiers 352, 356, but there is no other.

[0188] In the illustrated architecture 300, the signals output by the phase shifter 354 (via the amplifier 352 when it is present) are combined in the combiner 350. The combiner 350 in the architecture 300 combines the RF signals into one signal. The combiner 350 can be a passive combiner (e.g., not connected to a power source), which can result in some insertion loss. The combiner 350 can be an active combiner (e.g., connected to a power source), which can result in some signal gain. When the combiner 350 is an active combiner, it can provide a different (e.g., configurable) amount of gain for each input signal so that the input signals have the same amplitude when combined. When the combiner 350 is an active combiner, the combiner 350 may not need a second amplifier 352 because the active combiner can provide signal amplification.

[0189] The output of combiner 350 is input to mixers 348 and 346. Mixers 348 and 346 typically down-convert the received RF signal using inputs from local oscillators 372 and 370, respectively, to produce intermediate or baseband signals carrying the coded and modulated information. The output of mixers 348 and 346 is input to analog-to-digital converter (ADC) 344 for conversion to analog signals. The analog signal output from ADC 344 is input to modem 302 for baseband processing, such as decoding, deinterleaving, etc.

[0190] Architecture 300 is given as an example only to illustrate an architecture for sending and / or receiving signals. In some cases, architecture 300 and / or each part of architecture 300 can be repeated multiple times within the architecture to accommodate or provide any number of RF chains, antenna elements and / or antenna panels. In addition, many alternative architectures are possible and have been envisioned. For example, although only a single antenna array 318 is shown, two, three or more antenna arrays can be included, each with their own corresponding amplifiers, phase shifters, splitters, mixers, DACs, ADCs and / or modems. One or more. For example, a single UE may include two, four or more antenna arrays for sending or receiving signals at different physical locations on the UE or in different directions.

[0191] In addition, mixers, splitters, amplifiers, phase shifters and other components can be located in different signal type areas (e.g., represented by different reference numerals 322, 324, 326, 328) in the architecture of different implementations. For example, in different examples, splitting the signal to be transmitted into multiple signals can occur at analog RF, analog IF, analog baseband or digital baseband frequencies. Similarly, amplification and / or phase shifting can also occur at different frequencies. For example, in some aspects, one or more of the splitter 310, amplifiers 312, 316 or phase shifters 314 can be located between the DAC 304 and the first mixer 306 or between the first mixer 306 and the second mixer 308. In one example, the functions of one or more of the components can be combined into one component. For example, the phase shifter 314 can perform amplification to include or replace the first and / or second amplifiers 312, 316. As another example, the phase shift can be implemented by the second mixer 308 to eliminate the need for a separate phase shifter 314. This technique is sometimes referred to as a local oscillator (LO) phase shift. In certain aspects of this configuration, there may be multiple IF-to-RF mixers within the second mixer 308 (eg, for each antenna element chain), and the local oscillator B 332 may supply a different local oscillator signal (with a different phase offset) to each IF-to-RF mixer.

[0192] The modem 302 and / or the communication manager 334 can control one or more of the other components 304 to 372 to select one or more antenna elements 320 and / or form a beam for the transmission of one or more signals. For example, the antenna elements 320 can be individually selected or deselected for the transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers (such as the first amplifier 312 and / or the second amplifier 316). Beamforming includes using multiple signals on different antenna elements to generate beams, wherein one or more or all of the multiple signals are phase shifted relative to each other. The formed beams can carry physical or higher-level reference signals or information. When each of the multiple signals is radiated from the corresponding antenna element 320, the radiated signals interact, interfere (constructively and destructively) and amplify with each other to form the final beam. The shape (such as the amplitude, width, and / or presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array 318) can be dynamically controlled by modifying the phase shifts or phase offsets imparted by the phase shifters 314 and the amplitudes imparted by the amplifiers 312, 316 of the multiple signals relative to each other. The communication manager 334 can be partially or fully located within one or more other components of the architecture 300. For example, in some aspects, the communication manager 334 can be located within the modem 302.

[0193] The communication manager 334, the controller / processor 280, the receive processor 280, etc. can manage the measurement of the beam by the architecture 300. For example, this measurement can include determining the CSI based at least in part on the channel state information (CSI) reporting setting. The CSI can be based at least in part on layer 1 measurements, such as layer 1 reference signal received power (RSRP), layer 1 signal to interference and noise ratio (SINR) value, channel quality indicator (CQI), precoding matrix indicator (PMI), CSI reference signal (CSI-RS) resource indicator (CRI), strongest layer indication (SLI), rank indication (RI), etc. L1-RSRP and / or L1-SINR can be used for beam selection based at least in part on interference. The techniques and devices described herein provide dynamic indication of CSI reporting settings for determination and reporting of CSI, or selection of CSI reporting settings based at least in part on signal measurements and indication of the selected CSI reporting settings via UCI.

[0194] As mentioned above, providing Figure 3 As an example. Other examples may differ from the Figure 3 Examples described.

[0195] In wireless communications, CSI refers to the known channel properties of a communication link. Typically, CSI describes how a signal propagates from a transmitter to a receiver and represents the combined effects of, for example, scattering, fading, and power decay with distance.

[0196] In certain wireless communication systems (such as NR systems), a UE (e.g., UE 120) may be configured to report CSI to a base station (e.g., base station 110). The CSI report provided by the UE may include information associated with, for example, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI reference signal resource indicator (CRI), a strongest layer indication (SLI), a rank indication (RI), a layer 1 (L1) reference signal received power (RSRP), an L1 signal to interference and noise ratio (SINR), and the like.

[0197] In wireless communication systems (such as NR systems), there are three types of CSI reports: periodic, semi-persistent, and aperiodic. Periodic CSI reports can be carried on short PUCCH or long PUCCH. Semi-persistent CSI reports can be carried on long PUCCH or physical uplink shared channel (PUSCH). Downlink control information (DCI) can be used to semi-persistently allocate resources and / or modulation and coding schemes (MCS) for semi-persistent CSI reports carried on PUSCH. In addition, semi-persistent CSI reports support type II with a minimum period of 5 milliseconds (ms) and are not supported for aperiodic CSI reference signals. Periodic CSI reports and semi-persistent CSI reports support periodicity of 5 slots, 10 slots, 20 slots, 40 slots, 80 slots, 160 slots, and 320 slots. Aperiodic CSI reports can be carried on PUSCH multiplexed or non-multiplexed with uplink data.

[0198] In certain wireless communication systems (such as NR systems), L1-RSRP and / or L1-SINR can be used for beam management. For example, L1-SINR can be used for beam selection that takes interference into account (e.g., in a format similar to L1-RSRP). Typically, each configured report can report up to four beams. Here, an absolute SINR value can be reported for the first reported beam (e.g., the beam with the highest SINR), and a differential SINR value can be reported for each other beam, where a given differential SINR is calculated relative to the SINR associated with the first beam (e.g., the beam with the highest SINR).

[0199] CSI measurement and reporting may be based at least in part on a CSI reporting configuration. The CSI reporting configuration may be semi-statically configured (e.g., using radio resource control (RRC) signaling, etc.). The CSI reporting configuration may identify the periodicity for CSI reporting, the reference signal for CSI reporting, the resources associated with the CSI reporting, etc. CSI reporting may be performed periodically, semi-continuously, or aperiodically. Aperiodic CSI reporting may be triggered, while periodic and semi-continuous CSI reporting may be configured to be performed according to an interval.

[0200] The reliability of CSI reports (especially L1-RSRP and L1-SINR) is very important for beam reliability to support, for example, unicast coverage in frequency range 2 (FR2) (e.g., because beam management may need to be performed more frequently for unicast communications in FR2). It is worth noting that L1-RSRP or L1-SINR may be relatively large (e.g., on the order of 20 bits), which may lead to poor coverage of the physical uplink control channel (PUCCH) carrying the CSI report including such information. When combined with periodic CSI reporting, the larger size of CSI feedback in NR may lead to coverage issues and poor throughput. For example, the channel conditions at the UE may change faster than the update of the periodic CSI reporting configuration (e.g., in some cases, on a per-time slot basis), so the CSI feedback of the CSI report may be unreliable, thereby reducing network efficiency and using computational resources associated with retransmitting CSI feedback. This situation may be exacerbated for larger CSI reports, such as those including L1-RSRP / L1-SINR information, and for periodic CSI reporting using longer periodicity.

[0201] Certain aspects described herein provide techniques and apparatus for UE selection of CSI reporting parameters (or CSI reporting settings associated with CSI reporting parameters), such as dynamic signaling of CSI reporting parameters based at least in part on measurements made by the UE. Certain techniques and apparatus described herein provide an indication of the selected CSI reporting parameters via UCI. In certain aspects, the UE's selection of CSI reporting parameters and the indication of the selected CSI reporting parameters in the UCI can improve the coverage of the CSI reporting, thereby increasing the reliability of beam management performed at least in part based on CSI reporting (e.g., for unicast channels in FR2). In certain aspects, the UE can switch between two or more CSI reporting settings based at least in part on dynamic signaling. For example, the two or more CSI reporting settings can identify one or more different CSI reporting parameters, one or more different CSI reporting resources, and the like. In certain aspects, one or more of the CSI reporting settings (or CSI reporting parameters associated with the CSI reporting settings) can be associated with a coverage enhancement mode, or can be configured to provide improved coverage relative to another CSI reporting setting or CSI reporting configuration. This can include a configured grant, multiple repetitions of the PUCCH, and the like. Therefore, the flexibility of the CSI reporting configuration of the UE is improved, and the reliability of the CSI feedback sent by the UE is improved. In addition, network resources that would otherwise be used to semi-statically reconfigure the CSI reporting configuration and / or retransmit failed CSI feedback can be saved.

[0202] Figure 4is a diagram illustrating an example 400 associated with selection of CSI reporting parameters by a UE (eg, UE 120) and indication via UCI according to the present disclosure.

[0203] As shown in reference numeral 402, the UE may perform signal measurement. For example, the UE may measure the received power of a reference signal (e.g., a CSI reference signal (CSI-RS)) sent by a base station (e.g., base station 110). In certain aspects, the result of the signal measurement may be, for example, an L1-RSRP value, an L1-SINR value, a log-likelihood ratio (LLR) quality value, and the like.

[0204] As indicated by reference numeral 404, the UE may select a CSI reporting parameter based at least in part on a result of performing a signal measurement. In certain aspects, the UE may select the CSI reporting parameter from a plurality of CSI reporting parameters included in a CSI reporting configuration configured for the UE. That is, in the CSI reporting configuration, two or more configured CSI reporting parameters may be configured for the UE, and the UE may dynamically select the CSI reporting parameter based at least in part on a result of performing the signal measurement.

[0205] In certain aspects, a UE may receive a CSI reporting configuration including a plurality of CSI reporting parameters from a base station (eg, via radio resource control (RRC) signaling).

[0206] In certain aspects, as described above, a CSI reporting configuration may include a plurality of CSI reporting parameters. Here, each CSI reporting parameter may include information indicating a parameter on which the UE is to generate and / or send a CSI report based at least in part.

[0207] For example, in certain aspects, a first CSI reporting parameter among a plurality of CSI reporting parameters indicates a first setting for the reporting parameter, and a second CSI reporting parameter among the plurality of CSI reporting parameters indicates a second setting for the reporting parameter. As a specific example, a reporting parameter may be associated with whether CSI report repetition will be performed (e.g., whether the UE will send a CSI report multiple times to improve coverage). In this example, the first CSI reporting parameter may indicate that CSI report repetition is enabled, and the second CSI reporting parameter may indicate that CSI report repetition is disabled. As another example, a reporting parameter may be associated with a periodicity for CSI reporting. In this example, the first CSI reporting parameter may indicate a first periodicity for CSI reporting (e.g., a relatively short periodicity to improve coverage), and the second CSI reporting parameter may indicate a second periodicity for CSI reporting (e.g., a relatively long periodicity). As another example, a reporting parameter may be associated with a payload size for CSI reporting. In this example, the first CSI reporting parameter may indicate a first payload size for CSI reporting (e.g., a relatively smaller payload size to improve coverage), and the second CSI reporting parameter may indicate a second payload size for CSI reporting (e.g., a relatively larger payload size).

[0208] In certain aspects, the UE may select a CSI reporting parameter based at least in part on a criterion included in the CSI reporting configuration. In certain aspects, the criterion may include, for example, a signal strength threshold. In such a scenario, the UE may select a CSI reporting parameter based at least in part on whether the result of the signal measurement satisfies the signal strength threshold. For example, if the determined RSRP value does not satisfy the signal strength threshold, the UE may select a reporting parameter that causes CSI report repetition to be enabled. Alternatively, if the determined RSRP value satisfies the signal strength threshold, the UE may select a reporting parameter that causes CSI report repetition to be disabled.

[0209] As indicated by reference numeral 406, in the UCI, the UE may send and the base station may receive an indication of the selected CSI reporting parameter. That is, the UE may send the UCI including the indication of the CSI reporting parameter selected by the UE.

[0210] In certain aspects, the UCI may also include an indication of a gap length between the UCI and the start of CSI report repetition (e.g., when the CSI reporting parameters indicate that CSI report repetition is enabled), or an indication of a gap length between the UCI and the start of beam scanning. That is, in certain aspects, the UCI may indicate a gap between UCI transmission and CSI report repetition or a gap between UCI transmission and the performance of beam scanning.

[0211] Alternatively, in certain aspects, an indication of the length of the gap between the UCI and the start of the CSI report repetition or an indication of the length of the gap between the UCI and the start of the beam scanning may be included in the CSI report configuration. In such scenarios, the gap does not need to be indicated in the UCI because the base station already has access to the CSI report configuration.

[0212] In certain aspects, the UCI may also include an indication of the length of a gap between an initial transmission of a CSI report and the start of CSI report repetition (e.g., when the CSI reporting parameters indicate that CSI report repetition is enabled), or an indication of the length of a gap between an initial transmission of a CSI report and the start of beam scanning. That is, in certain aspects, the UCI may indicate a gap between an initial transmission of a CSI report and the activation of CSI report repetition, or a gap between an initial transmission of a CSI report and the activation of beam scanning.

[0213] Alternatively, in certain aspects, an indication of the length of the gap between the initial transmission of a CSI report and the start of a CSI report repetition or an indication of the length of the gap between the initial transmission of a CSI report and the start of beam scanning may be included in the CSI reporting configuration. In such scenarios, the gap does not need to be indicated in the UCI because the base station already has access to the CSI reporting configuration.

[0214] In certain aspects, the PUCCH format or PUCCH option to be used to indicate the selected CSI reporting parameters is pre-configured on the UE according to the wireless communication standard. That is, the PUCCH format or PUCCH option used to indicate the CSI reporting parameters selected by the UE may be specified in the standard specification (e.g., the PUCCH format may be limited to PUCCH format 0, PUCCH format 1, etc.). Alternatively, in certain aspects, information identifying the format to be used to indicate the selected CSI reporting parameters may be included in the CSI reporting configuration.

[0215] In certain aspects, the UE may receive an indication in a DCI sent by a base station (e.g., a DCI associated with triggering semi-persistent CSI reporting) to perform selection of CSI reporting parameters (e.g., an indication that the UE will perform CSI reporting parameter selection), or information identifying a PUCCH format that will be used to indicate the selected CSI reporting parameters.

[0216] As indicated at reference numeral 408, the UE may send a CSI report based at least in part on the selected CSI reporting parameter. Additionally, as indicated at reference numeral 410, the base station may monitor CSI reports from the UE based at least in part on the selected CSI reporting parameter.

[0217] In certain aspects, depending on CSI reporting parameters selected by the UE, the CSI report may be a coverage enhanced CSI report. A coverage enhanced CSI report includes a CSI report that is generated and / or sent in a manner that improves coverage of the CSI report (e.g., improves the likelihood that a base station will receive and successfully decode the CSI report). In certain aspects, coverage enhancement may be provided by CSI report repetition, meaning that the CSI report is sent at least twice by the UE. Thus, in certain aspects, sending the CSI report includes performing CSI report repetition.

[0218] In certain aspects, the UE and the base station may send and monitor CSI reports based at least in part on the selected CSI reporting parameters. For example, as described above, the selected CSI reporting parameters may indicate settings for reporting parameters associated with the CSI report (e.g., whether CSI report repetition is enabled, periodicity, payload size, etc.). Here, the UE and the base station may send and monitor CSI reports based at least in part on the settings for reporting parameters indicated by the selected CSI reporting parameters.

[0219] As mentioned above, providing Figure 4 As an example. Other examples may differ from the Figure 4 Examples described.

[0220] Figure 5 is a diagram illustrating an example 500 of dynamic indication for periodic CSI reporting according to the present disclosure. As shown, the example 500 includes a UE 120 and a BS 110. In certain aspects, the UE 120 and the BS 110 may communicate on a frequency band in a frequency range using beamforming, such as a frequency range (FR2), etc.

[0221] As indicated by reference numeral 510, BS 110 may provide configuration information to UE 120. The configuration information may identify two or more CSI reporting settings, such as for periodic CSI reporting. In certain aspects, the two or more CSI reporting settings may indicate one or more parameters or resources associated with CSI reporting (e.g., parameters for determining CSI feedback, resources for determining CSI feedback, resources for sending CSI feedback, etc.). In certain aspects, one of the signaled CSI reporting settings may identify a single parameter or a set of parameters to be used in relation to another CSI reporting configuration. For example, a CSI reporting setting may indicate a modification to another CSI reporting configuration (e.g., a baseline CSI reporting configuration). In this case, UE 120 may determine CSI reporting based on the baseline CSI reporting configuration until signaling indicating the use of the modification is received. Thereafter, UE 120 may use the modified CSI reporting configuration. In certain aspects, the two or more CSI reporting settings may include separate CSI reporting configurations, each CSI reporting configuration defining a complete set of parameters for determining and / or reporting CSI.

[0222] In certain aspects, a CSI reporting setting (e.g., a CSI reporting setting associated with a coverage enhancement mode) may indicate one or more repetitions of a physical uplink control channel (PUCCH) for transmitting CSI reports. In certain aspects, a CSI reporting setting (e.g., a CSI reporting setting associated with a coverage enhancement mode) may include or may be a grant for configuration of CSI report transmission on a physical uplink shared channel (PUSCH).

[0223] In certain aspects, a CSI reporting configuration for periodic CSI reporting may indicate a configured grant. For example, the CSI reporting configuration may be linked to the configured grant. In this case, the UE 120 may use the configured grant for CSI reporting based at least in part on the signaling indicating the selected CSI reporting setting. For example, the configured grant may be associated with the selected CSI reporting setting based at least in part on the CSI reporting configuration.

[0224] As shown in reference numeral 520, UE 120 may receive a signal indicating a switch to a selected CSI report setting in two or more CSI report settings. For example, the signal may be provided via DCI, MAC control element (MAC-CE), etc. Therefore, the signal may be considered as dynamic signaling. In some aspects, the signal may indicate a configured grant. For example, the signal may carry the configured grant on PUSCH. In this case, UE 120 may use the configured grant for CSI report transmission on PUSCH. In some aspects, BS 110 may determine the selected CSI report setting based at least in part on channel conditions at UE 120, based at least in part on failure to receive CSI reports from UE 120, etc. In some aspects, the signal may explicitly identify the selected CSI report setting. In some aspects, the signal may indicate switching the CSI report setting without explicitly indicating the CSI report setting. For example, UE 120 may switch between two or more CSI report settings in order based at least in part on receiving the signal, which reduces the overhead associated with indicating the CSI report setting.

[0225] As indicated by reference numeral 530, the UE 120 may switch to the selected CSI reporting setting. For example, the UE 120 may use the CSI reporting configuration identified by the selected CSI reporting setting, or may modify the baseline CSI reporting configuration according to the selected CSI reporting setting. As indicated by reference numeral 540, the UE 120 may determine the CSI report according to the selected CSI reporting setting. As indicated by reference numeral 550, the UE 120 may send the CSI report according to the selected CSI reporting setting. For example, the UE 120 may send the CSI report on the PUCCH (e.g., if the selected CSI reporting setting indicates the use of one or more repetitions, then one or more repetitions are used) and / or send the CSI report on the PUSCH (e.g., if the selected CSI reporting setting indicates the use of one or more repetitions, then one or more repetitions are used). Thus, the UE 120 may perform periodic CSI reporting according to the selected CSI reporting setting from among the two or more configured CSI reporting settings. Therefore, relative to the semi-static scheme for CSI reporting configuration, the reliability of CSI reporting can be improved in case of poor coverage, and the efficiency of CSI reporting can be improved in case of sufficient coverage.

[0226] As mentioned above, providing Figure 5 As an example. Other examples may differ from the Figure 5 Examples described.

[0227] Figure 6is a diagram illustrating an example process 600 performed, for example, by a UE in accordance with the present disclosure. Example process 600 is an example of operations in which a UE (eg, UE 120, etc.) performs operations associated with UE selection of CSI reporting parameters and indication via UCI.

[0228] like Figure 6 As shown, in certain aspects, process 600 may include performing signal measurements (block 610). For example, as described above, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may perform signal measurements.

[0229] like Figure 6 As further shown, in certain aspects, process 600 may include selecting a CSI reporting parameter from a plurality of CSI reporting parameters based at least in part on a result of performing a signal measurement, the plurality of CSI reporting parameters being included in a CSI reporting configuration configured for the UE (block 620). For example, as described above, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may select a CSI reporting parameter from a plurality of CSI reporting parameters based at least in part on a result of performing a signal measurement, the plurality of CSI reporting parameters being included in a CSI reporting configuration configured for the UE.

[0230] like Figure 6 As further shown in FIG. 6 , in certain aspects, process 600 may include sending an indication of the selected CSI reporting parameters in the UCI (block 630). For example, as described above, the user equipment (e.g., using transmit processor 264, controller / processor 280, memory 282, etc.) may send an indication of the selected CSI reporting parameters in the UCI.

[0231] Process 600 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.

[0232] In a first aspect, process 600 includes receiving a CSI reporting configuration including a plurality of CSI reporting parameters.

[0233] In a second aspect, alone or in combination with the first aspect, a CSI reporting configuration is received via radio resource control signaling.

[0234] In a third aspect, alone or in combination with one or more of the first and second aspects, a first CSI reporting parameter among the plurality of CSI reporting parameters indicates a first setting for a reporting parameter, and a second CSI reporting parameter among the plurality of CSI reporting parameters indicates a second setting for a reporting parameter. Here, the selected CSI reporting parameter is either the first CSI reporting parameter or the second CSI reporting parameter.

[0235] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the reporting parameters are associated with at least one of: whether CSI report repetition is to be performed, a periodicity for CSI reporting, or a payload size for CSI reporting.

[0236] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the result of the signal measurement includes at least one of the following: a reference signal received power value, a signal to interference and noise ratio value, or a log-likelihood ratio quality value.

[0237] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the UCI comprises an indication of a gap length between the UCI and a start of a CSI report repetition, or an indication of a gap length between the UCI and a start of a beam scan.

[0238] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, an indication of a gap length between UCI and the start of CSI reporting repetition or an indication of a gap length between UCI and the start of beam scanning is included in the CSI reporting configuration.

[0239] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, a PUCCH format or PUCCH option to be used to indicate the selected CSI reporting parameters is pre-configured on the UE according to the wireless communication standard.

[0240] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, information identifying a physical uplink control channel format to be used to indicate the selected CSI reporting parameters is included in the CSI reporting configuration.

[0241] In the tenth aspect, either alone or in combination with one or more of the first to ninth aspects, an indication of selection of CSI reporting parameters is received in downlink control information associated with triggering semi-persistent CSI reporting, or information identifying a physical uplink control channel format that will be used to indicate the selected CSI reporting parameters.

[0242] In an eleventh aspect, alone or in combination with one or more of the first to tenth aspects, the selected CSI reporting parameters are selected based at least in part on criteria included in the CSI reporting configuration.
