On-off keying configuration for channel state information feedback

Abstract

Systems and techniques are provided for wireless communications. For example, a network device can receive, from a network entity, an on-off keying (OOK) configuration for channel state information (CSI) feedback by the network device. The network device can generate a CSI report corresponding to a channel between the network device and the network entity. The generated CSI report is associated with a first time. The network device can compare the generated CSI report with a previous CSI report corresponding to the channel, the previous CSI report associated with a second time that is before the first time. The comparison is based on the OOK configuration. The network device can signal a corresponding CSI feedback to the network entity indicative of the generated CSI report. The corresponding CSI feedback is signaled to the network entity by transmission or non-transmission of the generated CSI report according to the comparison.

[0022] Certain aspects of this disclosure are provided below for illustration purposes. Alternate aspects may be devised without departing from the scope of the disclosure. Additionally, well-known elements of the disclosure will not be described in detail or will be omitted so as not to obscure the relevant details of the disclosure. Some of the aspects described herein may be applied independently and some of them may be applied in combination as would be apparent to those of skill in the art. In the following description, for the purposes of explanation, specific details are set forth in order to provide a thorough understanding of aspects of the application. However, it will be apparent that various aspects may be practiced without these specific details. The figures and description are not intended to be restrictive.

[0023] The ensuing description provides example aspects only, and is not intended to limit the scope, applicability, or configuration of the disclosure. Rather, the ensuing description of the example aspects will provide those skilled in the art with an enabling description for implementing an example aspect. It should be understood that various changes may be made in the function and arrangement of elements without departing from the scope of the application as set forth in the appended claims.

[0024] Wireless communication networks can be deployed to provide various communication services, such as voice, video, packet data, messaging, broadcast, any combination thereof, or other communication services. A wireless communication network may support both access links and sidelinks for communication between wireless devices. An access link may refer to any communication link between a client device (e.g., a user equipment (UE), a station (STA), or other client device) and a base station (e.g., a 3GPP gNB for 5G / NR, a 3GPP eNB for 4G / LTE. a Wi-Fi access point (AP), or other base station). For example, an access link may support uplink signaling, downlink signaling, connection procedures, etc. An example of an access link is a Uu link or interface (also referred to as an NR-Uu) between a 3 GPP gNB and a UE.

[0025] In various wireless communication networks (e.g., 4G / LTE, 5G / NR, 6G, and beyond), a UE can be configured to perform measurements of radio conditions of one or more communication channels. For example, a UE can perform measurements of radio conditions associated with a downlink channel between the UE and a network entity (e.g., base station, gNB, etc.). The radio conditions of the one or more communication channels may also be referred to as channel conditions. In some examples, a UE can performPATENTQualcomm Docket No 250104WO7measurements of one or more reference signals and / or can determine channel condition information for generating Channel State Information (CSI). CSI can refer to feedback (e.g., feedback information) provided by aUE to a network entity (e.g., base station, gNB, etc.) to indicate or describe the current wireless channel conditions as experienced by the UE. The network entity may use the CSI to optimize or adjust one or more transmission parameters for the channel(s) corresponding to the CSI. For example, the network entity can use CSI received from a UE to optimize transmission parameters such as beamforming, link adaptation. MIMO precoding, etc., for a downlink channel between the network entity and the UE.

[0026] In some wireless communications systems, feedback information associated with one or more communications channels can be used to dynamically adapt one or more communication link parameters according to time-varying channel conditions. For example, the time-varying channel conditions can be indicated and / or determined based on the feedback information. The one or more communication link parameters adapted based on the feedback information can be associated with one or more of a modulation and coding scheme (MCS), beamforming, multiple input multiple output (MIMO) layers, etc. The time-varying channel conditions indicated by the feedback information can correspond to changes with respect to UE mobility, weather conditions, scattering, fading, interference, noise, etc. In some cases, a UE can be configured to report channel state feedback (CSF) to a network entity (e.g., base station, gNB, etc.), and the network entity can use the CSF to adjust one or more communication parameters in response to the feedback from the UE.

[0027] CSF can be signaled using one or more channel state information (CSI) reports. A CSI report can be transmitted by a UE and received by a network entity, and may include one or more types of feedback information. The CSI report may be used to indicate, from a UE to a network entity', information corresponding to the channel conditions as observed by the UE. The network entity (e.g., base station, gNB. etc.) receiving a CSI report from a UE can use the channel condition observations from the UE to optimize and / or adjust parameters for link adaptation, beamforming, and / or scheduling, etc. CSF is a type of feedback that may be reported or signaled using a CSI report. For example, CSF may be a subset of the information that can be included in a CSI report. CSF may be used to indicate recommendations determined by the UE for variousPATENTQualcomm Docket No 250104WO8transmission parameter optimizations. For example, the CSF may indicate a precoding matrix indicator (PMI), corresponding to a preferred precoding matrix of the UE for MIMO transmissions. In some cases, the CSF can include an indication of a rank indicator (RI), corresponding to a number of spatial layers that the UE can support in the current channel conditions. In another example, CSF may indicate a channel quality indicator (CQI) value, corresponding to a suggested modulation and coding scheme (MCS) for the UE based on the observed channel quality for the current channel conditions, etc.

[0028] In an example CSI reporting procedure, a UE can perform periodic or aperiodic measurements of the downlink channel, and then reports these measurements to the network entity (e.g., gNB) associated with the downlink channel. Periodic measurements of the dow nlink channel can correspond to the UE generating and transmitting periodic CSI reports, which may be reported (e g., transmitted from the UE to the network entity) at a fixed time interval (e.g.. periodically). The fixed time interval may be a configured time duration configured by the network for the UE and / or for the periodic CSI reporting. A UE can autonomously generate and transmit the periodic CSI reports without being explicitly triggered by the netw ork entity . For example, the UE can generate and transmit a periodic CSI report at the corresponding fixed time interval for periodic CSI reporting, without the UE receiving a CSI report request from the network entity. In some cases, the periodic CSI report can be generated based on one or more measurements obtained by' the UE for a periodic reference signal on the downlink channel. The network entity' can transmit or broadcast the periodic reference signal(s) on the downlink channel according to the periodicity of the fixed time interval for periodic CSI reporting, where each periodic CSI report is associated with one or more reference signal (RS) measurement occasions w here the netw ork entity7transmits or broadcasts the reference signal(s) to be measured.

[0029] In an aperiodic CSI reporting procedure, the UE can be triggered to generate and transmit a CSI report in response to an explicit request from the network entity7. For example, a network entity7may transmit (and a UE may receive) signaling from the network entity indicative of a request for the aperiodic CSI report. In some cases, the request can be a downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) for the UE, where the scheduled PUSCH data transmission is the time at which the UE is expected to transmit the aperiodic CSI report. In some cases, aperiodic CSI reporting may be used in scenarios where the measured channel conditions arePATENTQualcomm Docket No 250104WO9changing more rapidly and / or are changing with greater magnitude changes between consecutive periodic CSI reporting occasions. In some cases, aperiodic CSI reporting can be configured for relatively high velocity scenarios and / or relatively high mobility UEs, where movement of the UE causes the physical path of the channel between the UE and the network entity to vary at a relatively high rate.

[0030] In some examples, one or more consecutive aperiodic and / or periodic CSI reports transmitted by a UE can be the same and / or highly similar, with channel measurement information values that are the same or approximately equal across the consecutive CSI reports. For example, the channel measurement information can be identical across consecutive CSI reports in relatively low velocity scenarios, where the UE is stationary or moving at a slow velocity. Stationary and / or low-velocity UE scenarios can be associated with more stable and unchanging channel conditions, and the consecutive CSI reports (e.g., which provide feedback and measurements of the channel conditions at different moments in time) can be the same (e.g., identical, equal, approximately equal, and / or similar, etc.).

[0031] Transmitting multiple periodic or aperiodic CSI reports that are each indicative of the same channel measurement information or values can be inefficient in UE power consumption (e.g., an inefficient use of the limited battery power storage of the UE to receive and measure CSI-RS, process the measurements to generate the CSI report, and transmit the generated CSI report). Transmitting multiple periodic or aperiodic CSI reports with the same channel measurement information or values can additionally be an inefficient use of the limited capacity and bandwidth of the wireless network, which has a finite number of time / frequency resources.

[0032] It may be desirable for systems and techniques that can be used for CSI report power saving for a UE, and / or that can be used to reduce interference and / or network congestion associated with one or more UEs transmitting consecutive CSI reports for unchanged channel measurement information. For example, it may be desirable to reduce the transmission of multiple periodic or aperiodic CSI reports with the same channel measurement information to reduce the inter-UE uplink interference for multiplexed physical uplink control channel (PUCCH) over a shared set of time / frequency resources of the wireless network. It may further be desirable to reduce the cross-cell UE uplink interference that may be associated with the transmission of multiple periodic or aperiodicPATENTQualcomm Docket No 250104WO10CSI reports with the same channel measurement information

[0033] Systems, apparatuses, processes (also referred to as methods), and computer-readable media (collectively referred to as ‘‘systems and techniques’") are described herein that can be used to provide CSI report power saving for uplink transmissions of one or more UEs. For example, the systems and techniques can be used to reduce the uplink transmission power expenditure of a UE associated with CSI feedback of one or more periodic and / or aperiodic CSI reports transmitted by the UE to a network entity7(e.g., gNB, base station, etc.). In some examples, the systems and techniques can be used to configure on-off keying (OOK) for the feedback of CSI reports from the UE to the network entity. For example, the network entity can transmit (and the UE can receive) an OOK configuration that causes the UE to use an On-Off-Keying waveform for the CSI report transmission from the UE to the network entity. Based on the OOK configuration and / or the corresponding OOK waveform, the UE can be configured to transmit a CSI report at a scheduled occasion (e.g., scheduled PUCCH, PUSCH, etc.) in response to a determination that the CSI report carries a different information from a previous CSI report transmitted by the UE.

[0034] For example, the UE can compare a currently generated CSI report to the last CSI report the UE transmitted to the network entity7. Based on the currently generated CSI report and the last CSI report carrying the same (e.g., identical, equal, etc.) information of the downlink channel, the UE may skip transmission of the generated CSI report. To skip transmission of the generated CSI report, the UE does not perform transmission. For example, the UE does not perform transmission of the generated CSI report or associated information. In some cases, the UE performs non-transmission of the generated CSI report after evaluating the generated CSI report against the last transmitted CSI report, and determining there are no changes to the measurement information of the downlink channel (or other channel for which the CSI report is generated). Non-transmission of the generated CSI report can correspond to the UE using discontinuous transmission (DTX) for a PUCCH scheduled for a transmission of the generated CSI report.

[0035] Based on the network entity having transmitted the OOK configuration to the UE, and / or based on the network entity having transmitted an indication to the UE to enable an OOK configuration, the network entity7can be configured to perform DTX detection during the scheduled resources of the PUCCH associated with a CSI report. ForPATENTQualcomm Docket No 250104WO11example, for the scheduled time / frequency resources of an expected CSI report transmission from the UE, the network entity can detect DTX when the network entity¬ does not receive the scheduled PUCCH transmission corresponding to the CSI report. From the UE. The detected DTX can cause the network entity to reuse the last or most recent CSI report that was received from the UE, based on treating the DTX (e.g., the non-reception of the expected CSI report) as an implicit indication that the UE generated the expected CSI report and determined that the measurement information was unchanged from the last transmitted CSI report.

[0036] Further aspects of the systems and techniques will be described with respect to the figures.

[0037] As used herein, the phrase “based on” shall not be construed as a reference to a closed set of information, one or more conditions, one or more factors, or the like. In other words, the phrase “based on A” (where “A” may be information, a condition, a factor, or the like) shall be construed as “based at least on A” unless specifically recited differently.

[0038] As used herein, the terms “user equipment” (UE) and “network entity” are not intended to be specific or otherwise limited to any particular radio access technology (RAT), unless otherwise noted. In general, a UE may be any wireless communication device (e.g., a mobile phone, router, tablet computer, laptop computer, and / or tracking device, etc.), wearable (e.g., smartwatch, smart-glasses, wearable ring, and / or an extended reality (XR) device such as a virtual reality (VR) headset, an augmented reality (AR) headset or glasses, or a mixed reality (MR) headset), vehicle (e.g., automobile, motorcycle, bicycle, etc.), aircraft (e.g., an airplane, jet, unmanned aerial vehicle (UAV) or drone, helicopter, airship, glider, etc ), and / or Internet of Things (loT) device, etc., used by a user to communicate over a wireless communications network. A UE may be mobile or may (e.g., at certain times) be stationary, and may communicate with a radio access network (RAN). As used herein, the term “UE” may be referred to interchangeably as an “access terminal” or “AT,” a “client device,” a “wireless device," a “subscriber device,” a “subscriber terminal,” a “subscriber station,” a “user terminal” or “UT,” a “mobile device,” a “mobile terminal,” a “mobile station,” or variations thereof. Generally, UEs can communicate with a core netw ork via a RAN, and through the core netw ork the UEs can be connected with external networks such as the Internet and with other UEs. Of course, other mechanisms of connecting to the core network and / or the Internet are alsoPATENTQualcomm Docket No 250104WO12possible for the UEs, such as over wired access networks, wireless local area network (WLAN) networks (e.g., based on IEEE 802.11 communication standards, etc.), and so on.

[0039] A network entity can be implemented in an aggregated or monolithic base station architecture, or alternatively, in a disaggregated base station architecture, and may include one or more of a central unit (CU), a distributed unit (DU), a radio unit (RU), a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or aNon-Real Time (Non-RT) RIC. Abase station (e g., with an aggregated / monolithic base station architecture or disaggregated base station architecture) may operate according to one of several RATs in communication with UEs depending on the network in which it is deployed, and may be alternatively referred to as an access point (AP), a network node, a NodeB (NB), an evolved NodeB (eNB), a next generation eNB (ng-eNB), a New Radio (NR) Node B (also referred to as a gNB or gNodeB). etc. A base station may be used primarily to support wireless access by UEs, including supporting data, voice, and / or signaling connections for the supported UEs. In some systems, a base station may provide edge node signaling functions while in other systems it may provide additional control and / or network management functions. A communication link through which UEs can send signals to a base station is called an uplink (UL) channel (e.g., a reverse traffic channel, a reverse control channel, an access channel, etc ). A communication link through which the base station can send signals to UEs is called a downlink (DL) or forward link channel (e.g., a paging channel, a control channel, a broadcast channel, or a forward traffic channel, etc.). The term traffic channel (TCH). as used herein, can refer to either an uplink, reverse or downlink, and / or a forward traffic channel.

[0040] The term “network entity’’ or “base station” (e g., with an aggregated / monolithic base station architecture or disaggregated base station architecture) may refer to a single physical transmit receive point (TRP) or to multiple physical TRPs that may or may not be co-located. For example, where the term “network entity” or “base station” refers to a single physical TRP, the physical TRP may be an antenna of the base station corresponding to a cell (or several cell sectors) of the base station. Where the term “network entity” or “base station” refers to multiple co-located physical TRPs, the physical TRPs may be an array of antennas (e.g., as in a multiple-input multiple-output (M1M0) system or where the base station employs beamforming) of the base station.PATENTQualcomm Docket No 250104WO13Where the term “base station” refers to multiple non-co-located physical TRPs, the physical TRPs may be a distributed antenna system (DAS) (e.g., a network of spatially separated antennas connected to a common source via a transport medium) or a remote radio head (RRH) (e.g.. a remote base station connected to a serving base station). Alternatively, the non-co-located physical TRPs may be the serving base station receiving the measurement report from the UE and a neighbor base station whose reference radio frequency (RF) signals (e.g., or simply “reference signals”) the UE is measuring. Because a TRP is the point from which a base station transmits and receives wireless signals, as used herein, references to transmission from or reception at a base station are to be understood as referring to a particular TRP of the base station.

[0041] In some implementations that support positioning of UEs, a network entity or base station may not support wireless access by UEs (e.g., may not support data, voice, and / or signaling connections for UEs). but may instead transmit reference signals to UEs to be measured by the UEs, and / or may receive and measure signals transmitted by the UEs. Such a base station may be referred to as a positioning beacon (e.g., when transmitting signals to UEs) and / or as a location measurement unit (e.g., when receiving and measuring signals from UEs).

[0042] As described herein, a node (which may be referred to as a node, a network node, a network entity, or a wireless node) may include, be, or be included in (e.g., be a component of) a base station (e.g., any base station described herein), a UE (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, a processing system, an integrated access and backhauling (IAB) node, a distributed unit (DU), a central unit (CU), a remote unit (RU), and / or another processing entity configured to perform any of the techniques described herein. For example, a network node may be a UE. As another example, a network node may be a base station or network entity. As another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a UE. In another aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a base station. In yet other aspects of this example, the first, second, and third network nodes may be different relative to these examples. Similarly, reference to a UE, basePATENTQualcomm Docket No 250104WO14station, apparatus, device, computing system, processing system, or the like may include disclosure of the UE, base station, apparatus, device, computing system, processing system, or the like being a network node. For example, disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node. Consistent with this disclosure, once a specific example is broadened in accordance with this disclosure (e.g., a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node), the broader example of the narrower example may be interpreted in the reverse, but in a broad open-ended way. In the example above where a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node, the first network node may refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first processing system, a first one or more components, a first processing entity, or the like configured to receive the information; and the second network node may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second processing system, a second one or more components, a second processing entity, or the like.

[0043] As described herein, a network entity (which may alternatively be referred to as an entity, a node, a network node, or a wireless entity) may be, be similar to, include, or be included in (e.g., be a component of) a base station (e.g., any base station described herein, including a disaggregated base station), a UE (e.g., any UE described herein), a reduced capability (RedCap) device, an enhanced reduced capability (eRedCap) device, an ambient intemet-of-things (loT) device, an energy harvesting (EH)-capable device, a network controller, an apparatus, a device, a computing system, a processing system, an integrated access and backhauling (IAB) node, a distributed unit (DU), a central unit (CU). a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, a network entity may be a UE. As another example, a network entity may be a base station. As used herein, “network entity'’ may refer to an entity that is configured to operate in a network, such as the network 100 of FIG. 1. For example, a “network entity” is not limited to an entity that is currently located in and / orPATENTQualcomm Docket No 250104WO15currently operating in the network. Rather, a network entity may be any entity' that is capable of communicating and / or operating in the network.

[0044] The adjectives “first,” “second,” “third,” and so on are used for contextual distinction between two or more of the modified noun in connection with a discussion and are not meant to be absolute modifiers that apply only to a certain respective entity throughout the entire document. For example, a network entity' may be referred to as a “first network entity” in connection with one discussion and may be referred to as a “second network entity” in connection with another discussion, or vice versa. As an example, a first network entity may be configured to communicate with a second network entity or a third network entity. Tn one aspect of this example, the first network entity may be a UE, the second network entity may be a base station, and the third netw ork entity' may be a UE. In another aspect of this example, the first network entity may be a UE, the second network entity may be a base station, and the third network entity may be a base station. In yet other aspects of this example, the first, second, and third netw ork entities may be different relative to these examples.

[0045] Similarly, reference to a UE, base station, network node, apparatus, device, computing system, processing system or the like may include disclosure of the UE, base station, network node, apparatus, device, computing system, processing system or the like being a network entity. For example, disclosure that a UE is configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity. Consistent with this disclosure, once a specific example is broadened in accordance with this disclosure (e.g.. a UE is configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity), the broader example of the narrower example may be interpreted in the reverse, but in a broad open-ended way. In the example above where a UE is configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity, the first network entity may refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first processing system, a first set of one or more one or more components, a first processing entity', or the like configured to receive the information; and the second network entity may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, aPATENTQualcomm Docket No 250104WO16second processing system, a second set of one or more components, a second processing entity, or the like.

[0046] As described herein, communication of information (e.g., any information, signal, or the like) may be described in various aspects using different terminology. Disclosure of one communication term includes disclosure of other communication terms. For example, a first network entity may be described as being configured to transmit information to a second network entity7. In this example and consistent with this disclosure, disclosure that the first network entity is configured to transmit information to the second network entity includes disclosure that the first network entity is configured to provide, send, output, communicate, or transmit information to the second network entity7. Similarly, in this example and consistent with this disclosure, disclosure that the first network entity7is configured to transmit information to the second network entity includes disclosure that the second network entity is configured to receive, obtain, or decode the information that is provided, sent, output, communicated, or transmitted by the first network entity7.

[0047] In some examples, the network entity7102 may include a processing system (e.g., such as the processing system 470 of FIG. 4 and / or the processing system 902 of FIG. 9, etc.). Similarly, the network entity 180 (e.g., a millimeter wave (mmW) base station, etc.) may include a respective processing system (e.g., such as the processing system 470 of FIG. 4 and / or the processing system 902 of FIG. 9, etc.). A processing system may include one or more components (or subcomponents), such as one or more components described herein. For example, a respective component of the one or more components may be, be similar to, include, or be included in at least one memory, at least one communication interface, or at least one processor. For example, a processing system may include one or more components. In such an example, the one or more components may include a first component, a second component, and a third component. In this example, the first component may be coupled to a second component and a third component. In this example, the first component may be at least one processor, the second component may be a communication interface, and the third component may be at least one memory. A processing system may generally be a system including one or more components that may perform one or more functions, such as any function or combination of functions described herein. For example, one or more components may receive input informationPATENTQualcomm Docket No 250104WO17(e.g., any information that is an input, such as a signal, any digital information, or any other information), one or more components may process the input information to generate output information (e.g., any information that is an output, such as a signal or any other information), one or more components may perform any function as described herein, or any combination thereof. As described herein, an “input’’ and “input information” may be used interchangeably. Similarly, as described herein, an “output” and “output information” may be used interchangeably. Any information generated by any component may be provided to one or more other systems or components of, for example, a network entity described herein). For example, a processing system may include a first component configured to receive or obtain information, a second component configured to process the information to generate output information, and / or a third component configured to provide the output information to other systems or components. In this example, the first component may be a communication interface (e.g., a first communication interface), the second component may be at least one processor (e.g., that is coupled to the communication interface and / or at least one memory), and the third component may be a communication interface (e.g., the first communication interface or a second communication interface). For example, a processing system may include at least one memory, at least one communication interface, and / or at least one processor, where the at least one processor may, for example, be coupled to the at least one memory and the at least one communication interface.

[0048] A processing system of a network entity described herein may interface with one or more other components of the network entity, may process information received from one or more other components (such as input information), or may output information to one or more other components. For example, a processing system may include a first component configured to interface with one or more other components of the network entity to receive or obtain information, a second component configured to process the information to generate one or more outputs, and / or a third component configured to output the one or more outputs to one or more other components. In this example, the first component may be a communication interface (e.g., a first communication interface), the second component may be at least one processor (e.g., that is coupled to the communication interface and / or at least one memory), and the third component may be a communication interface (e.g., the first communication interface or a second communication interface). For example, a chip or modem of the network entityPATENTQualcomm Docket No 250104WO18may include a processing system. The processing system may include a first communication interface to receive or obtain information, and a second communication interface to output, transmit, or provide information. In some examples, the first communication interface may be an interface configured to receive input information, and the information may be provided to the processing system. In some examples, the second system interface may be configured to transmit information output from the chip or modem. The second communication interface may also obtain or receive input information, and the first communication interface may also output, transmit, or provide information.

[0049] An RF signal comprises an electromagnetic wave of a given frequency that transports information through the space between a transmitter and a receiver. As used herein, a transmitter may transmit a single “RF signal” or multiple “RF signals” to a receiver. However, the receiver may receive multiple “RF signals” corresponding to each transmitted RF signal due to the propagation characteristics of RF signals through multipath channels. The same transmitted RF signal on different paths between the transmitter and receiver may be referred to as a “multipath” RF signal. As used herein, an RF signal may also be referred to as a “wireless signal” or simply a “signal” where it is clear from the context that the term “signal” refers to a wireless signal or an RF signal.

[0050] Various aspects of the systems and techniques described herein will be discussed below with respect to the figures. According to various aspects, FIG. 1 illustrates an example of a wireless communications system 100. The wireless communications system 100 (e.g.. which may also be referred to as a wireless wide area network (WWAN)) can include various base stations 102 and various UEs 104. In some aspects, the base stations 102 may also be referred to as “network entities” or “network nodes.” One or more of the base stations 102 can be implemented in an aggregated or monolithic base station architecture. Additionally, or alternatively, one or more of the base stations 102 can be implemented in a disaggregated base station architecture, and may include one or more of a central unit (CU), a distributed unit (DU), a radio unit (RU), a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or a Non-Real Time (Non-RT) RIC. The base stations 102 can include macro cell base stations (e.g., high power cellular base stations) and / or small cell base stations (e.g., low power cellular base stations). In an aspect, the macro cell base station may include eNBs and / or ng-eNBs where the wirelessPATENTQualcomm Docket No 250104WO19communications system 100 corresponds to a long-term evolution (LTE) network, or gNBs where the wireless communications system 100 corresponds to a NR network, or a combination of both, and the small cell base stations may include femtocells, picocells, microcells, etc.

[0051] The base stations 102 may collectively form a RAN and interface with a core network 170 (e.g., an evolved packet core (EPC) or a 5G core (5GC)) through backhaul links 122, and through the core network 170 to one or more location servers 172 (e.g., which may be part of core network 170 or may be external to core network 170). In addition to other functions, the base stations 102 may perform functions that relate to one or more of transferring user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, RAN sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment trace, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through the EPC or 5GC) over backhaul links 134, which may be wired and / or wireless.

[0052] The base stations 102 may wirelessly communicate with the UEs 104. Each of the base stations 102 may provide communication coverage for a respective geographic coverage area 110. In an aspect, one or more cells may be supported by abase station 102 in each coverage area 110. A "‘cell’' is a logical communication entity used for communication with a base station (e.g., over some frequency resource, referred to as a carrier frequency, component carrier, carrier, band, or the like), and may be associated with an identifier (e.g., a physical cell identifier (PCI), a virtual cell identifier (VCI), a cell global identifier (CGI)) for distinguishing cells operating via the same or a different carrier frequency. In some cases, different cells may be configured according to different protocol types (e.g., machine-type communication (MTC), narrowband loT (NB-IoT), enhanced mobile broadband (eMBB), or others) that may provide access for different types of UEs. Because a cell is supported by a specific base station, the term “cell'’ may refer to either or both of the logical communication entity and the base station that supports it, depending on the context. In addition, because a TRP is typically the physicalPATENTQualcomm Docket No 250104WO20transmission point of a cell, the terms “cell” and “TRP” may be used interchangeably. In some cases, the term “cell” may also refer to a geographic coverage area of a base station (e.g., a sector), insofar as a carrier frequency can be detected and used for communication within some portion of geographic coverage areas 110.

[0053] While neighboring macro cell base station 102 geographic coverage areas 110 may partially overlap (e.g., in a handover region), some of the geographic coverage areas 110 may be substantially overlapped by a larger geographic coverage area 110. For example, a small cell base station 102' may have a coverage area 110' that substantially overlaps with the coverage area 110 of one or more macro cell base stations 102. A network that includes both small cell and macro cell base stations may be known as a heterogeneous network. A heterogeneous network may also include home eNBs (HeNBs), which may provide service to a restricted group known as a closed subscriber group (CSG).

[0054] The communication links 120 between the base stations 102 and the UEs 104 may include uplink (e g., also referred to as reverse link) transmissions from a UE 104 to a base station 102 and / or downlink (e.g., also referred to as forward link) transmissions from a base station 102 to a UE 104. The communication links 120 may use MIMO antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links 120 may be provided using one or more carrier frequencies. Allocation of carriers may be asymmetric with respect to downlink and uplink (e.g., a greater or lesser quantity of carriers may be allocated for downlink than for uplink).

[0055] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., one or more of the base stations 102, UEs 104, etc.) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be implemented based on combining the signals communicated via antenna elements of an antenna array such that some signals propagating at particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applyingPATENTQualcomm Docket No 250104WO21amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).

[0056] A transmitting device and / or a receiving device (e.g., such as one or more of base stations 102 and / or UEs 104) may use beam sweeping techniques as part of beam forming operations. For example, a base station 102 (e.g., or other transmitting device) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 104 (e.g., or other receiving device). Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by base station 102 (or other transmitting device) multiple times in different directions. For example, the base station 102 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device, such as a base station 102, or by a receiving device, such as a UE 104) a beam direction for later transmission or reception by the base station 102.

[0057] Some signals, such as data signals associated with a particular receiving device, may be transmitted by a base station 102 in a single beam direction (e.g., a direction associated with the receiving device, such as a UE 104). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted in one or more beam directions. For example, a UE 104 may receive one or more of the signals transmitted by the base station 102 in different directions and may report to the base station 102 an indication of the signal that the UE 104 received with a highest signal quality or an otherwise acceptable signal quality.

[0058] In some examples, transmissions by a device (e.g., by a base station 102 or a UE 104) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from a base station 102 to a UE 104, from a transmitting device to a receiving device, etc.). The UE 104 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond toPATENTQualcomm Docket No 250104WO22a configured number of beams across a system bandw idth or one or more sub-bands. The base station 102 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), etc.), which may be precoded or unprecoded. The UE 104 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multipanel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted in one or more directions by a base station 102, a UE 104 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 104) or for transmitting a signal in a single direction (e.g., for transmitting data to a receiving device).

[0059] A receiving device (e.g., a UE 104) may try multiple receive configurations (e.g., directional listening) when receiving various signals from the base station 102, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may tty' multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as ‘listening"’ according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0060] The wireless communications system 100 may further include a WEAN AP 150 in communication with WLAN stations (STAs) 152 via communication links 154 in an unlicensed frequency spectrum (e.g., 5 Gigahertz (GHz)). When communicating in an unlicensed frequency spectrum, the WLAN STAs 152 and / or the WLAN AP 150 mayPATENTQualcomm Docket No 250104WO23perform a clear channel assessment (CCA) or listen before talk (LBT) procedure prior to communicating in order to determine whether the channel is available. In some examples, the wireless communications system 100 can include devices (e.g., UEs, etc.) that communicate with one or more UEs 104, base stations 102, APs 150, etc., utilizing the ultra- wideband (UWB) spectrum. The UWB spectrum can range from 3.1 to 10.5 GHz.

[0061] The small cell base station 102' may operate in a licensed and / or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell base station 102' may employ LTE or NR technology- and use the same 5 GHz unlicensed frequency spectrum as used by the WLAN AP 150. The small cell base station 102'. employing LTE and / or 5G in an unlicensed frequency spectrum, may boost coverage to and / or increase capacity of the access network. NR in unlicensed spectrum may be referred to as NR-U. LTE in an unlicensed spectrum may be referred to as LTE-U, licensed assisted access (LAA). or MulteFire.

[0062] The wireless communications system 100 may further include a millimeter wave (mmW) base station 180 that may operate in mmW frequencies and / or near mmW frequencies in communication with a UE 182. The mmW base station 180 may be implemented in an aggregated or monolithic base station architecture, or alternatively, in a disaggregated base station architecture (e.g., including one or more of a CU, a DU, a RU, a Near-RT RIC, or a Non-RT RIC). Extremely high frequency (EHF) is part of the RF in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters. Radio waves in this band may be referred to as a millimeter wave. Near mmW may extend down to a frequency of 3 GHz with a wavelength of 100 millimeters. The super high frequency (SHF) band extends between 3 GHz and 30 GHz, also referred to as centimeter wave. Communications using the mmW and / or near mmW radio frequency7band have high path loss and a relatively short range. The mmW base station 180 and the UE 182 may utilize beamforming (e.g., transmit and / or receive) over an mmW communication link 184 to compensate for the extremely high path loss and short range. Further, it will be appreciated that in alternative configurations, one or more base stations 102 may also transmit using mmW or near mmW and beamforming. Accordingly, it will be appreciated that the foregoing illustrations are merely examples and should not be construed to limit the various aspects disclosed herein.PATENTQualcomm Docket No 250104WO24

[0063] In some aspects relating to 5G, the frequency spectrum in which wireless network nodes or entities (e.g., base stations 102 / 180, UEs 104 / 182) operate is divided into multiple frequency ranges, FR1 (e.g., from 450 to 6,000 Megahertz (MHz)), FR2 (e.g., from 24,250 to 52,600 MHz), FR3 (e.g., above 52,600 MHz), and FR4 (e.g., between FR1 and FR2). In a multi-carrier system, such as 5G, one of the carrier frequencies is referred to as the “primary carrier” or “anchor carrier” or “primary serving cell” or “PCell,” and the remaining carrier frequencies are referred to as “secondary carriers” or “secondary serving cells” or “SCells.” In carrier aggregation, the anchor carrier is the carrier operating on the primary frequency (e.g., FR1) utilized by a UE 104 / 182 and the cell in which the UE 104 / 182 either performs the initial radio resource control (RRC) connection establishment procedure or initiates the RRC connection reestablishment procedure. The primary carrier carries all common and UE-specific control channels and may be a carrier in a licensed frequency (however, this is not always the case). A secondary carrier is a carrier operating on a second frequency (e.g., FR2) that may be configured once the RRC connection is established between the UE 104 and the anchor carrier and that may be used to provide additional radio resources. In some cases, the secondary’ carrier may be a carrier in an unlicensed frequency. The secondary carrier may contain only necessary signaling information and signals, for example, those that are UE-specific may not be present in the secondary carrier, since both primary’ uplink and downlink carriers are ty pically UE-specific. This means that different UEs 104 / 182 in a cell may have different downlink primary’ carriers. The same is true for the uplink primary carriers. The network is able to change the primary carrier of any UE 104 / 182 at any time. This is done, for example, to balance the load on different carriers. Because a “serving cell” (e.g., whether a PCell or an SCell) corresponds to a carrier frequency and / or component carrier over which some base station is communicating, the term “cell,” “serving cell,” “component carrier,” "carrier frequency,” and the like can be used interchangeably.

[0064] For example, still referring to FIG. 1, one of the frequencies utilized by the macro cell base stations 102 may be an anchor carrier (or “PCell”) and other frequencies utilized by the macro cell base stations 102 and / or the mmW base station 180 may be secondary carriers (“SCells”). In carrier aggregation, the base stations 102 and / or the UEs 104 may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100 MHz) bandwidth per carrier up to a total of Yx MHz (e.g., x component carriers) for transmission in each direction.PATENTQualcomm Docket No 250104WO25The component carriers may or may not be adjacent to each other on the frequency spectrum. Allocation of carriers may be asymmetric with respect to the downlink and uplink (e.g., a greater or lesser quantity of carriers may be allocated for downlink than for uplink). The simultaneous transmission and / or reception of multiple carriers enables the UE 104 / 182 to significantly increase its data transmission and / or reception rates. For example, two 20 MHz aggregated carriers in a multi-carrier system would theoretically lead to a two-fold increase in data rate (e.g., 40 MHz), compared to that attained by a single 20 MHz carrier.

[0065] In order to operate on multiple carrier frequencies, a base station 102 and / or a UE 104 can be equipped with multiple receivers and / or transmitters. For example, a UE 104 may have two receivers, “Receiver 1” and “Receiver 2,” where “Receiver 1” is a multi-band receiver that can be tuned to band (e.g., carrier frequency) ‘X’ or band ‘Y,’ and “Receiver 2" is a one-band receiver tunable to band Z only. In this example, if the UE 104 is being served in band ‘X,’ band ‘X’ would be referred to as the PCell or the active carrier frequency, and “Receiver 1” would need to tune from band ‘X’ to band ‘Y’ (e.g., an SC ell) in order to measure band ‘Y’ (and vice versa). In contrast, whether the UE 104 is being served in band ‘X’ or band ‘Y,’ because of the separate “Receiver 2,’" the UE 104 can measure band "Z’ without interrupting the service on band ‘X’ or band ‘Y’

[0066] The wireless communications system 100 may further include a UE 164 that may communicate with a macro cell base station 102 over a communication link 120 and / or the mmW base station 180 over an mmW communication link 184. For example, the macro cell base station 102 may support a PCell and one or more SCells for the UE 164 and the mmW base station 180 may support one or more SCells for the UE 164.

[0067] The wireless communications system 100 may further include one or more UEs, such as UE 190, that connects indirectly to one or more communication networks via one or more device-to-device (D2D) peer-to-peer (P2P) links (e.g., referred to as “sidelinks”). In the example of FIG. 1, UE 190 has a D2D P2P link 192 with one of the UEs 104 connected to one of the base stations 102 (e.g., through which UE 190 may indirectly obtain cellular connectivity) and a D2D P2P link 194 with WLAN STA 152 connected to the WLAN AP 150 (e.g., through which UE 190 may indirectly obtain WLAN-based Internet connectivity). In an example, the D2D P2P links 192 and 194 may be supportedPATENTQualcomm Docket No 250104WO26with any well-known D2D RAT, such as LTE Direct (LTE-D), Wi-Fi Direct (Wi-Fi-D), Bluetooth®, and so on.

[0068] FIG. 2 illustrates a block diagram of an example architecture 200 of a base station 102 and a UE 104 that enables transmission and processing of signals exchanged between the UE and the base station, in accordance with some aspects of the present disclosure. Example architecture 200 includes components of a base station 102 and a UE 104, which may be one of the base stations 102 and one of the UEs 104 illustrated in FIG. 1. Base station 102 may be equipped with T antennas 234a through 2341, and UE 104 may be equipped with R antennas 252a through 252r, where in general T>1 and R>1.

[0069] At base station 102, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi -static resource partitioning information (SRPI) and / or the like) and control information (e.g., CQI requests, grants, upper layer signaling, and / or the like) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g.. the cell-specific reference signal (CRS)) and synchronization signals (e.g., the primary synchronization signal (PSS) and secondary synchronization signal (SSS)). Atransmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. The modulators 232a through 232t are shown as a combined modulator-demodulator (MOD-DEMOD). In some cases, the modulators and demodulators can be separate components. Each modulator of the modulators 232a to 232t may process a respective output symbol stream (e.g., for an orthogonal frequencydivision multiplexing (OFDM) scheme and / or the like) to obtain an output sample stream. Each modulator of the modulators 232a to 232t may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals may be transmitted from modulators 232a to 232t via T antennas 234a through 234t, respectively. According to certain aspects descnbed in morePATENTQualcomm Docket No 250104WO27detail below, the synchronization signals can be generated with location encoding to convey additional information.

[0070] At UE 104, antennas 252a through 252r may receive the downlink signals from base station 102 and / or other base stations and may provide received signals to one or more demodulators (DEMODs) 254a through 254r, respectively. The demodulators 254a through 254r are shown as a combined modulator-demodulator (MOD-DEMOD). In some cases, the modulators and demodulators can be separate components. Each demodulator of the demodulators 254a through 254r may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator of the demodulators 254a through 254r may further process the input samples (e g., for OFDM and / or the like) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 104 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. A channel processor may determine reference signal received power (RSRP), received signal strength indicator (RS SI), reference signal received quality (RSRQ), channel quality indicator (CQI), and / or the like.

[0071] On the uplink, at UE 104, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, and / or the like) from controller / processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals (e g., based on a beta value or a set of beta values associated with the one or more reference signals). The symbols from transmit processor 264 may be precoded by a TX-MIMO processor 266, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, and / or the like), and transmitted to base station 102. At base station 102, the uplink signals from UE 104 and other UEs may be received by antennas 234a through 234t, processed by demodulators 232a through 232t, detected by a MIMO detector 236 (e.g., if applicable), and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 104. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller (e.g., processor) 240. Base station 102 may include communication unit 244 and communicate to a net orkPATENTQualcomm Docket No 250104WO28controller 231 via communication unit 244. Network controller 231 may include communication unit 294, controller / processor 290, and memory 292.

[0072] In some aspects, one or more components of UE 104 may be included in a housing. Controller 240 of base station 102. controller / processor 280 of UE 104, and / or any other component(s) of FIG. 2 may perform one or more techniques associated with implicit UCI beta value determination for NR.

[0073] Memories 242 and 282 may store data and program codes for the base station 102 and the UE 104, respectively. A scheduler 246 may schedule UEs for data transmission on the downlink, uplink, and / or sidelink.

[0074] In some aspects, deployment of communication systems, such as 5G new radio (NR) systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility7element of a network, a radio access network (RAN) node, a core network node, a network element, or a network equipment, such as a base station (BS), or one or more units (or one or more components) performing base station functionality, may be implemented in an aggregated or disaggregated architecture. For example, a BS (e g., such as a Node B (NB), evolved NB (eNB), NR BS, 5GNB, access point (AP), a transmit receive point (TRP), or a cell, etc.) may be implemented as an aggregated base station (e.g., also known as a standalone BS or a monolithic BS) or a disaggregated base station.

[0075] An aggregated base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A disaggregated base station may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (e.g., such as one or more central or centralized units (CUs), one or more distributed units (DUs). or one or more radio units (RUs)). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be colocated with the CU, or alternatively, may be geographically or virtually distributed throughout one or multiple other RAN nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU and RU also can be implemented as virtual units, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).PATENTQualcomm Docket No 250104WO29

[0076] Base station-tjpe operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may¬ be utilized in an integrated access backhaul (IAB) network, an open radio access network (0-RAN (e.g., such as the network configuration sponsored by the 0-RAN Alliance)), or a virtualized radio access network (e.g., vRAN, also known as a cloud radio access network (C-RAN)). Disaggregation may include distributing functionality across two or more units at various physical locations, as well as distributing functionality for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station, or disaggregated RAN architecture, can be configured for wired or wireless communication with at least one other unit.

[0077] FIG. 3 is a diagram illustrating an example disaggregated base station 300 architecture. The disaggregated base station 300 architecture may include one or more central units (CUs) 310 that can communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated base station units (e.g., such as a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) 325 via an E2 link, or a Non-Real Time (Non-RT) RIC 315 associated with a Service Management and Orchestration (SMO) Framework 305, or both). A CU 310 may communicate with one or more distributed units (DUs) 330 via respective midhaul links, such as an Fl interface. The DUs 330 may communicate with one or more radio units (RUs) 340 via respective fronthaul links. The RUs 340 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be simultaneously served by multiple RUs 340.

[0078] Each of the units (e.g., the CUs 310. the DUs 330, the RUs 340, as well as the Near-RT RICs 325, the Non-RT RICs 315, and the SMO Framework 305) illustrated in FIG. 3 and / or described herein may include one or more interfaces or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (e.g., collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other units. Additionally, the units can include a wireless interface, whichPATENTQualcomm Docket No 250104WO30may include a receiver, a transmitter or transceiver (e.g., such as a radio frequency (RF) transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.

[0079] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., Central Unit - User Plane (CU-UP)), control plane functionality (e.g., Central Unit - Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as the El interface when implemented in an O-RAN configuration. The CU 310 can be implemented to communicate with the DU 330, as necessary, for network control and signaling.

[0080] The DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (e.g., such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, or the like) depending on a functional split, such as those defined by the 3rd Generation Partnership Proj ect (3GPP). In some aspects, the DU 330 may further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330, or with the control functions hosted by the CU 310.

[0081] Lower-layer functionality can be implemented by one or more RUs 340. In some deployments, an RU 340, controlled by a DU 330, may correspond to a logical node that hosts RF processing functions, or low- PHY layer functions (e.g., such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical randomaccess channel (PRACH) extraction and filtering, or the like), or both, based on the functional split, such as a lower layer functional split. In such an architecture, the RU(s) 340 can be implemented to handle over the air (OTA) communication with one or morePATENTQualcomm Docket No 250104WO31UEs 104. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s) 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration can enable the DU(s) 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0082] The SMO Framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (e.g., such as an 01 interface). For virtualized network elements, the SMO Framework 305 may be configured to interact with a cloud computing platform (e.g., such as an open cloud (O-Cloud) 390) to perform network element life cycle management (e.g., such as to instantiate virtualized network elements) via a cloud computing platform interface (e.g., such as an 02 interface). Such virtualized network elements can include, but are not limited to, CUs 310, DUs 330, RUs 340, and Near-RT RICs 325. In some implementations, the SMO Framework 305 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 311, via an 01 interface. Additionally, in some implementations, the SMO Framework 305 can communicate directly with one or more RUs 340 via an 01 interface. The SMO Framework 305 also may include aNon-RT RIC 315 configured to support functionality of the SMO Framework 305.

[0083] The Non-RT RIC 315 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence / Machine Learning (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near-RT RIC 325. The Non-RT RIC 315 may be coupled to or communicate with (e.g., such as via an Al interface) the Near-RT RIC 325. The Near-RT RIC 325 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (e.g., such as via an E2 interface) connecting one or more CUs 310, one or more DUs 330, or both, as well as an O-eNB, w ith the Near-RT RIC 325.

[0084] In some implementations, to generate AI / ML models to be deployed in the Near-RT RIC 325, the Non-RT RIC 315 may receive parameters or external enrichmentPATENTQualcomm Docket No 250104WO32information from external servers. Such information may be utilized by the Near-RT RIC 325 and may be received at the SMO Framework 305 or the Non-RT RIC 315 from nonnetwork data sources or from network functions. In some examples, the Non-RT RIC 315 or the Near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 315 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO Framework 305 (e.g., such as reconfiguration via 01) or via creation of RAN management policies (e.g.. such as Al policies).

In some cases, the wireless device 407 may also be referred to as a user computing device. The wireless device 407 may include a client device such as a UE (e.g., UE 104, UE 152, UE 190) or other type of device (e.g., a station (STA) configured to communication using a Wi-Fi interface) that may be used by an end-user. In some cases, the processing system 470 of the wireless device 407 can be implemented by one or more of the UEs 104 of FIG. 1. For example, the wireless device 407 may include a mobile phone, router, tablet computer, laptop computer, tracking device, wearable device (e.g., a smart watch, glasses, an extended reality (XR) device such as a virtual reality (VR), augmented reality (AR), or mixed reality (MR) device, etc.), Internet of Things (loT) device, a vehicle, an aircraft, and / or another device that is configured to communicate over a wireless communications network.

[0086] The processing system 470 includes software and hardware components that may be electrically or communicatively coupled via a bus 489 (e.g., or may otherwise be in communication, as appropriate). The processing system 470 may generally be a system including one or more components that may perform one or more functions, such as any function or combination of functions described herein. For example, one or more components may receive input information (e.g., any information that is an input, such asPATENTQualcomm Docket No 250104WO33a signal, any digital information, or any other information), one or more components may process the input information to generate output information (e.g., any information that is an output, such as a signal or any other information), one or more components may perform any function as described herein, or any combination thereof. For example, the processing system 470 includes one or more processors 484. The one or more processors 484 may include one or more CPUs, ASICs, FPGAs, APs, GPUs, VPUs, NSPs, microcontrollers, dedicated hardware, any combination thereof, and / or other processing device or system. The bus 489 may be used by the one or more processors 484 to communicate between cores and / or with the one or more memory devices 486.

[0087] The processing system 470 may also include one or more memory devices 486, one or more digital signal processors (DSPs) 482, one or more SIMs 474, one or more modems 476. one or more wireless transceivers 478, an antenna 487, one or more input devices 472 (e.g., a camera, a mouse, a keyboard, a touch sensitive screen, a touch pad. a keypad, a microphone, and / or the like), and one or more output devices 480 (e.g., a display, a speaker, a printer, and / or the like).

[0088] In some aspects, processing system 470 may include one or more radio frequency (RF) interfaces configured to transmit and / or receive RF signals. In some examples, an RF interface may include components such as modem(s) 476, wireless transceiver(s) 478, and / or antennas 487. The one or more wireless transceivers 478 may transmit and receive wireless signals (e.g., signal 488) via antenna 487 from one or more other devices, such as other wireless devices, network devices (e.g., base stations such as eNBs and / or gNBs, Wi-Fi access points (APs) such as routers, range extenders or the like, etc.), cloud networks, and / or the like. In some examples, the processing system 470 may include multiple antennas or an antenna array that may facilitate simultaneous transmit and receive functionality. Antenna 487 may be an omnidirectional antenna such that radio frequency (RF) signals may be received from and transmitted in all directions. The wireless signal 488 may be transmitted via a wireless network. The wireless network may be any wireless network, such as a cellular or telecommunications network (e.g., 3G, 4G, 5G, etc.), wireless local area network (e.g., a Wi-Fi network), a Bluetooth™ network, and / or other network.

[0089] In some examples, the wireless signal 488 may be transmitted directly to other wireless devices using sidelink communications (e.g., using a PC5 interface, using aPATENTQualcomm Docket No 250104WO34DSRC interface, etc.). Wireless transceivers 478 may be configured to transmit RF signals for performing sidelink communications via antenna 487 in accordance with one or more transmit power parameters that may be associated with one or more regulation modes. Wireless transceivers 478 may also be configured to receive sidelink communication signals having different signal parameters from other wireless devices.

[0090] In some examples, the one or more wireless transceivers 478 may include an RF front end including one or more components, such as an amplifier, a mixer (e.g., also referred to as a signal multiplier) for signal down conversion, a frequency synthesizer (e.g., also referred to as an oscillator) that provides signals to the mixer, a baseband filter, an analog-to-digital converter (ADC), one or more power amplifiers, among other components. The RF front-end may generally handle selection and conversion of the wireless signals 488 into a baseband or intermediate frequency and may convert the RF signals to the digital domain.

[0091] In some cases, the processing system 470 may include a coding-decoding device (or CODEC) configured to encode and / or decode data transmitted and / or received using the one or more wireless transceivers 478. In some cases, the processing system 470 may include an encryption-decryption device or component configured to encrypt and / or decrypt data (e.g., according to the AES and / or DES standard) transmitted and / or received by the one or more wireless transceivers 478.

[0092] The one or more SIMs 474 may each securely store an international mobile subscriber identity (IMSI) number and related key assigned to the user of the wireless device 407. The IMSI and key may be used to identify and authenticate the subscriber when accessing a network provided by a network service provider or operator associated with the one or more SIMs 474. The one or more modems 476 may modulate one or more signals to encode information for transmission using the one or more wireless transceivers 478. The one or more modems 476 may also demodulate signals received by the one or more wireless transceivers 478 in order to decode the transmitted information. In some examples, the one or more modems 476 may include a Wi-Fi modem, a 4G (or LTE) modem, a 5G (or NR) modem, and / or other types of modems. The one or more modems 476 and the one or more wireless transceivers 478 may be used for communicating data for the one or more SIMs 474.PATENTQualcomm Docket No 250104WO35

[0093] The processing system 470 may also include (and / or be in communication with) one or more non- transitory machine-readable storage media or storage devices (e.g., one or more memory devices 486). which may include, without limitation, local and / or network accessible storage, a disk drive, a drive array, an optical storage device, a solid-state storage device such as a RAM and / or a ROM, which may be programmable, flash-updateable, and / or the like.

[0095] FIG. 5A is a diagram illustrating an example 500 of physical channels and reference signals in a wireless network. In some examples, one or more downlink channels and one or more downlink reference signals may carry information from a base station 102 to a UE 104. One or more uplink channels and one or more uplink reference signals may cany' information from UE 104 to base station 102.

[0096] In some aspects, a downlink channel may include one or more of a physical downlink control channel (PDCCH) that carries downlink control information (DCI), a physical downlink shared channel (PDSCH) that carries downlink data, and / or a physical broadcast channel (PBCH) that carries system information, among other examples. In some aspects, PDSCH communications may be scheduled by PDCCH communications.

[0097] In some examples, an uplink channel may include one or more of a physical uplink control channel (PUCCH) that carries uplink control information (UCI), a physical uplink shared channel (PUS CH) that carries uplink data, and / or a physical random access channel (PRACH) used for initial network access, among other examples. In some aspects, UE 104 may transmit acknowledgement (ACK) or negative acknowledgementPATENTQualcomm Docket No 250104WO36(NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in UCI on the PUCCH and / or the PUSCH.

[0098] In some cases, a downlink reference signal may include one or more of a synchronization signal block (SSB). a channel state information (CSI) reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), and / or a phase tracking reference signal (PTRS), among other examples. In some examples, an uplink reference signal may include one or more of a sounding reference signal (SRS). a DMRS, and / or a PTRS, among other examples.

[0099] An SSB may carry or include information used for initial network acquisition and synchronization. For example, an SSB can cany' or include one or more of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH, and / or a PBCH DMRS. An SSB may also be referred to as a synchronization signal / PBCH (SS / PBCH) block. In some aspects, base station 102 may transmit multiple SSBs on multiple corresponding beams, and the SSBs may be used for beam selection.

[0100] A CSI-RS may carry information used for downlink channel estimation (e.g., downlink CSI acquisition), which may be used for scheduling, link adaptation, or beam management, among other examples. For example, base station 102 can configure a set of CSI-RSs for UE 104, and UE 104 can measure the configured set of CSI-RSs. Based on the CSI-RS measurements, UE 104 can perform channel estimation and report channel estimation parameters to base station 102 (e.g., in a CSI report). For example, the channel estimation parameters can include one or more of a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a layer indicator (LI), a rank indicator (RI), and / or a reference signal received power (RSRP), among other examples.

[0101] In some examples, base station 102 can use the CSI report to select transmission parameters for downlink communications to UE 104. For example, base station 102 can use the CSI report to select transmission parameters that include one or more of a quantity of transmission layers (e.g., a rank), a precoding matrix (e.g.. a precoder), a modulation and coding scheme (MCS), and / or a refined downlink beam (e.g., using a beam refinement procedure or a beam management procedure), among other examples.PATENTQualcomm Docket No 250104WO37

[0102] A DMRS may carry information used to estimate a radio channel for demodulation of an associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of a DMRS may be specific to a physical channel for which the DMRS is used for estimation. DMRSs are UE-specific, can be beamformed, can be confined in a scheduled resource (e.g., rather than transmitted on a wideband), and can be transmitted only when necessary. As shown. DMRSs are used for both downlink communications and uplink communications.

[0103] APTRS can cany information used to compensate for oscillator phase noise. In some cases, oscillator phase noise may increase as an oscillator carrier frequency increases. In some examples, a PTRS can be utilized at high carrier frequencies (e.g., such as millimeter w ave frequencies) to mitigate oscillator phase noise. The PTRS may be used to track the phase of the local oscillator and to enable suppression of phase noise and common phase error (CPE). As illustrated in FIG. 5A. in some examples one or more PTRSs can be used for both downlink communications (e.g., on the PDSCH) and uplink communications (e.g., on the PUSCH).

[0104] A PRS may cany' information associated with timing or ranging measurements of UE 104. For example, UE 104 may utilize one or more signals (e.g., PRSs) transmitted by base station 102 to improve an observed time difference of arrival (OTDOA) positioning performance. In some examples, a PRS may be a pseudo-random Quadrature Phase Shift Keying (QPSK) sequence mapped in diagonal patterns with shifts in frequency and time to avoid collision with cell-specific reference signals and control channels (e.g., a PDCCH). A PRS can be designed to improve detectability by UE 104, which may need to detect downlink signals from multiple neighboring base stations in order to perform OTDOA-based positioning. Accordingly, UE 104 may receive a PRS from multiple cells (e.g., a reference cell and one or more neighbor cells), and may report a reference signal time difference (RSTD) based on OTDOA measurements associated with the PRSs received from the multiple cells. In some aspects, base station 102 can calculate a position of UE 104 based on the RSTD measurements reported by UE 104.

[0105] In some examples, an SRS can carry information used for uplink channel estimation, which may be used for scheduling, link adaptation, precoder selection, and / or beam management, among other examples. Base station 102 can configure one or more SRS resource sets for UE 104, and UE 104 can transmit SRSs on the configured SRSPATENTQualcomm Docket No 250104WO38resource sets. An SRS resource set may have a configured usage, such as uplink CSI acquisition, downlink CSI acquisition for reciprocity -based operations, uplink beam management, among other examples. Base station 102 may measure the SRSs. may perform channel estimation based on the measurements, and / or may use the SRS measurements to configure communications with UE 104.

[0106] In some cases, a UE may receive a reference signal (e.g., a CSI-RS, an SSB, a DMRS, etc.) from a network entity' (or another UE) and can report channel state feedback (CSF) to the network entity (or the other UE), where the CSF is determined based on measurements of the reference signal received at the UE. In some cases, a UE may also transmit a reference signal (e.g., CSI-RS, DMRS, PT-RS, SRS, etc.), and a network entity (or another UE) may determine characteristics associated with the channel based on measurements of the received reference signal.

[0107] FIG. 5B is a diagram illustrating an example of a process flow 550 for providing CSF associated with a communications channel between a network entity 502 and a UE 504. In some aspects, the netw ork entity 502 may be an example of the BS 102 depicted and described with respect to FIG. 1 and 2, or a disaggregated base station depicted and described with respect to FIG. 3. Similarly, the UE 504 may be an example of the UE 104 depicted and described with respect to FIGS. 1-3 and / or may be an example of the wireless device 407 of FIG. 4, etc. In other aspects, UE 504 may be another type of wireless communications device and / or network entity 502 may be another type of network entity' or network node, such as those described herein.

[0108] Process flow 550 can begin at 506 in FIG. 5B, with UE 504 receiving a reference signal (e.g., such as CSI-RS) from network entity 502.

[0109] At 508. UE 504 performs channel calculations based on the reference signal, such as determining a channel estimate H based on the received reference signal. For example, the UE 504 may include a demodulator, which may be part of a transceiver (e.g., transceiver 254 of FIG. 2), an RX MIMO detector (e.g., RX MIMO detector 256 of FIG.2), and / or a receive processor (e.g.. receive processor 258 of FIG. 2) of UE 504. The demodulator, such as a component of the demodulator, may take as input the reference signal as received over multiple antennas of the UE 504 and output a vector y that is a representation of the received reference signal as received over each of the multiple antennas of the UE 504. Based on a received signal model, the vector y can be representedPATENTQualcomm Docket No 250104WO39as: y = Hx + if, where H corresponds to a matrix representation of the communications channel (e.g., as in a channel estimate of the communications channel the signal is communicated in, which may be a dow nlink communication channel where the reference signal is communicated).

[0110] The term % is a vector representing symbols transmitted by network entity 502 over a number of spatial layers, and n represents noise across the communications channel. In some cases, H may have a size equal to the number of antennas used to receive the signaling, Nant. multiplied by the number of spatial layers. V / , (e.g.. the number of beamformed transmissions, number of antenna ports, etc.). For example, H can be configured to have a number of rows equal to Nantand a number of columns equal to Ni. In some aspects, the symbols that form the reference signal are known by the UE 504 (e.g., configured or preconfigured at the UE), and UE 504 can determine the channel estimate H based on receiving the reference signal. In some aspects, UE 504 may further calculate, as part of the channel calculations, T on the channel estimate H. For example, UE 504 may be configured to perform singular value decomposition (SVD) based precoding to determine the precoder V. For example, SVD( / 7) = [US F], such that SVD provides the precoder V. U may be related to the ordering of the rows of H. as in the ordering of the antennas as represented by H. Other suitable techniques may also be used to determine the precoder V based on the channel estimate H.[OHl] At 510, UE 504 sends to network entity 502 CSF, for example as a CSI report, indicating the determined channel estimate H and / or precoder V. For example, the UE 504 may determine one or more CSI parameters (e.g., such as CQI, PMI, and / or RI. etc.). In some cases, the one or more CSI parameters can be determined or estimated by the UE 504 based on the channel estimate H and / or based on the determined precoder information V. In some cases, one or more CSI parameters that include and / or are based on RI may represent a number of MIMO layers requested by the UE 504 for dow nlink transmissions.

[0112] In some examples, one or more CSI parameters that include and / or are based on PMI may be indicative of a set of indices corresponding to one or more precoding matrices (e.g., the precoding matrix F) to apply to downlink transmissions. In some aspects, the PMI may indicate a preferred precoding of UE 504 for the downlink transmissions on the PDSCH. In some cases, one or more CSI parameters can include and / or may be based on CQI information, where the CQI can be implemented or used asPATENTQualcomm Docket No 250104WO40an indicator of channel quality (e.g., for example, corresponding to the channel estimate H, etc.). The UE 504 may send an indication of the one or more determined CSI parameters to the network entity 502 in a CSI report. The network entity 502 may transmit downlink data transmissions to the UE 504 based on the information received by the network entity 502 in a CSI report from the UE 504 (e.g., such as the CSI report of 510).

[0113] For example, the network entity 502 may perform precoding to transmit one or more down I ink data transmissions to UE 504, where the network entity 502 performs the precoding for the UE 504 based on precoding information determined based on the received CSI report from the UE 504. Precoding can be based on manipulating transmitted signals prior to transmission to optimize the corresponding received signal(s) at a receiver. In some examples, a network entity and / or a UE may implement precoding to maximize signal-to-noise ratio (SNR), minimize interference, and / or increase overall system capacity, etc. In some cases, precoding can be used to support multi-layer transmission in a MIMO system. For example, using precoding, multiple streams may be transmitted from transmit antennas at the network entity with independent and appropriate weighting per antenna such that the throughput is maximized at the UE output.

[0114] In some examples, a UE can be configured to provide feedback information (e.g., CSI feedback, CSI reports, precoding feedback, etc.) corresponding to MIMO transmissions and / or multi-path channels and / or multiple beams. For example, the feedback information can correspond to multiple beams, where each beam and a corresponding coefficient reflect a path with a certain angle. In some cases, a UE can be configured to provide feedback information in a multipath scattering environment with diverse angle spread and delay spread (e.g., where delay spread is the difference in time between the arrival of a first copy and a lost copy of a signal at a receiver, corresponding to the multipath propagation of the signal in multiple copies).

[0115] As noted above, systems and techniques are provided that can be used to provide CSI report power saving for uplink transmissions of one or more UEs. For example, the systems and techniques can be used to provide an on-off-keying (OOK) configuration for CSI feedback between a UE and a network entity (e.g., gNB, base station, etc.), where the CSI feedback is performed using an OOK waveform to transmit or not transmit each CSI report based on a difference between each CSI report and the most recently transmitted, prior CSI report. If the current CSI report carries the same information as thePATENTQualcomm Docket No 250104WO41last transmitted CSI report, the UE can be configured by the OOK configuration to not transmit the current CSI report by skipping a scheduled PUCCH for the current CSI report. Not transmitting the CSI report can comprise an implicit signaling (e.g., implicit indication) from the UE to the network entity that the CSI report is unchanged from the last CSI report transmitted by the UE (e.g., the most recent CSI report received by the network entity from the UE), and the network entity' can reuse the measurement information from this last transmitted CSI report.

[0116] The non-transmission of consecutive periodic or aperiodic CSI reports carry ing the same measurement information of a channel (e.g.. downlink channel between the UE and the network entity, etc.) can save power consumption at the UE. The channel state indication associated with the CSI reporting and feedback can be associated with a large volume and / or number of uplink transmissions by UEs on a wireless network. The CSI reporting and feedback procedure configures UEs to perform periodic and / or aperiodic measurements of the downlink channel, and to report these measurements to the network entity' (e.g., base station, gNB, etc.) as CSI feedback and / or a CSI report. The CSI feedback process may be used for the prediction of the channel response and / or one or more derivatives of the channel response (e.g., such as SNR, rank, etc.).

[0117] The predicted channel response and / or derived values can correspond to conditions that are predicted to be experienced by the UE on the downlink channel during the time of the next downlink transmission from the network entity' to the UE. For example, the CSI feedback process can be used to predict the channel response, SNR, rank, etc., that would be experienced by the UE for the next downlink transmission from the network entity to the UE. Based on the predictions, the network entity can optimize and / or adjust downlink parameters of an upcoming downlink transmission, before performing the downlink transmission. For example, the network entity (e.g., base station, gNB, etc.) may use predicted channel response and / or other derived parameters from the CSF and / or CSI report information to optimize and / or adjust at least one of channel precoding, modulation and coding scheme (MCS), allocation size and position, rank, etc.

[0118] In some cases, aperiodic CSI reporting may be used in scenarios where the measured channel conditions are changing more rapidly and / or are changing with greater magnitude changes between consecutive periodic CSI reporting occasions. In some cases, aperiodic CSI reporting can be configured for relatively high velocity scenarios and / orPATENTQualcomm Docket No 250104WO42relatively high mobility UEs, where movement of the UE causes the physical path of the channel between the UE and the network entity to vary at a relatively high rate. In some examples, one or more consecutive aperiodic and / or periodic CSI reports transmitted by a UE can be the same and / or highly similar, with channel measurement information values that are the same or approximately equal across the consecutive CSI reports. For example, the channel measurement information can be identical across consecutive CSI reports in relatively low velocity scenarios, where the UE is stationary or moving at a slow velocity. Stationary and / or low-velocity UE scenarios can be associated with more stable and unchanging channel conditions, and the consecutive CSI reports (e.g., which provide feedback and measurements of the channel conditions at different moments in time) can be the same (e.g., identical, equal, approximately equal, and / or similar, etc.).

[0119] In relatively low velocity scenarios of a UE (e.g.. where the speed or velocity' of a UE is relatively low (e.g., slow) and / or is below a configured threshold velocity, etc ), the channel response may vary more slowly and / or infrequently (e.g., low pace, slow rate, etc., of changes in channel conditions measured by the UE for the CSI reporting procedure, etc.). In some cases, a low velocity7scenario corresponds to examples or scenarios where the UE is moving at a speed or velocity that is less than a configured threshold value of the speed or velocity. In some examples, a low velocity scenario can be based on the rate of change or pace of change in channel conditions measured by the UE for periodic or aperiodic CSI reporting.

[0120] For example, a low velocity7scenario of the UE may be based on the velocity7of UE movement relative to the network entity, and the low velocity7scenario can correspond to channel response varying at a low pace. In another example, a low velocity scenario of the UE can be based on the channel response vary ing at a low pace. In an illustrative example, a low velocity7scenario of the UE may be a scenario or example where a high percentage (e.g., percentage above a threshold, etc.) of the consecutive CSI reports generated and transmitted by the UE are expected to remain the same. For example, if channel conditions do not change between two consecutive CSI report occasions, the measurement information carried by7each CSI report may be expected to also not change, and the two consecutive CSI reports may be identical (e.g., the same, etc.).

[0121] As noted above, the systems and techniques can be used to provide an on-off-keying (OOK) configuration for CSI report power saving for UE uplink transmission. On-PATENTQualcomm Docket No 250104WO43off-keying may be implemented as a form of binary modulation scheme, where the presence or absence of a signal represents binary7information. For example, presence of a configured signal for the on-off-keying can indicate a first information, and absence of the configured signal can indicate a different, second information. The mapping between the respective information indicated by the presence or absence of the signaled can be configured by the OOK configuration.

[0122] For example, in 5GNR systems, OOK can be used for Scheduling Request (SR), where the UE transmits a PUCCH in one or more PUCCH resources for a corresponding SR configuration. In the example of OOK for SR. the UE transmits a PUCCH in the PUCCH resource only when the UE transmits a positive SR using PUCCH format 0 or PUCCH format 1. In another example, a 5G NR system can use OOK for a paging monitoring indication during connected mode discontinuous reception (C-DRX) using a low-power wake-up signal (LP-WUS), which can be implemented as an OOK waveform with an overlaid OFDM sequence for conveying a wake-up indication and / or SCC dormancy indication. In some cases, a 4G / LTE system can use OOK for Scheduling Request only, for example while transmitting PUCCH format 1 for positive SR on the SR resources. In some examples, explicit OOK may be used for examples where the Scheduling Request and an ACK / NACK are transmitted on the same subframe. When SR and ACK / NACK are on the same subframe, a transmitting device can perform the transmission using either the SR resources (e.g., for positive SR) or the ACK / NACK resources (e.g., for negative SR). In some cases, RACH can be a type of OOK with an overlaid OFDM signal used to indicate and / or convey additional information such as a RACH sequence number, etc.

[0123] In one illustrative example, the systems and techniques described herein can provide an OOK configuration for CSI reporting by a UE, where the OOK configuration is indicative of a corresponding on-off-keying waveform (OOK waveform) to provide first CSI feedback by transmitting a CSI report using the scheduled time / frequency resources for the CSI report, and to provide a second CSI feedback by not transmitting the CSI report expected by the network entity' for the scheduled time / frequency resources.

[0124] The first CSI feedback corresponding to transmission of the CSI report can be explicit CSI feedback, corresponding to or comprising the first ty pe of infonnation signaled by the presence of a signal according to the OOK configuration. The second CSIPATENTQualcomm Docket No 250104WO44feedback corresponding to non-transmission of the CSI report can be implicit CSI feedback, corresponding to or comprising the second type of information that is signaled by the absence of the signal according to the OOK configuration.

[0125] FIG. 6 is a call flow diagram illustrating an example processing flow 600 for a UE configured to use on-off-keying for CSI report transmission, which may be CSI report transmission over PUCCH. The processing flow 600 can correspond to a UE 602, which may be the same as or similar to one or more of the UEs of FIGS. 1-5, and a network entity 604, which may be similar to one or more of the network entities and / or base stations, etc., of any FIGS. 1-5, etc.

[0126] In some aspects, the on-off-keying for CSI report transmission (e.g., CSI reports over PUCCH) can be implemented based on and / or using an OOK configuration 615, which may be transmitted from the network entity 604 to the UE 602. In some aspects, the OOK configuration 615 can include one or more parameters, values, information, etc., that are determined by the network entity 604 based at least in part on a velocity corresponding to the UE 602. For example, the network entity 604 may enable the OOK configuration 615 for lower velocities of the UE 602, for example an estimated UE velocity 614 that is less than (e.g., slower than) a configured threshold velocity, etc. In some cases, the network entity 604 may disable the OOK configuration 615 in response to an estimated velocity of the UE 602 exceeding the configured threshold.

[0127] In some aspects, the UE 602 can be configured to perform velocity estimation 612. Based on the velocity estimation 612, the UE 602 can transmit a corresponding velocity indication 614 to the network entity' 604, where the velocity indication 614 includes and / or indicates the estimated velocity of the UE 602. In some cases, the estimated velocity of the velocity indication 614 can be a measured velocity determined using one or more sensors of the UE 602 during the velocity estimation 612. In some cases, the velocity indication can include a range of velocities for the UE 602 and / or may include a time-series of estimated velocities for the UE 602, etc. Based on the velocity indication information 614, the network entity 604 may determine to transmit the OOK configuration 615. For example, the OOK configuration 615 may, in some cases, be in response to the velocity indication 614 and / or a determination based on the velocity indication 614 that the UE 602 velocity is less than a configured threshold. In some aspects, one or more parameters of the OOK configuration 615 can be determined,PATENTQualcomm Docket No 250104WO45adjusted, and / or modified, etc., by the network entity 604 based at least in part on the velocity' indication information 614.

[0128] In some cases, the estimated velocity information 614 for the UE 602 is determined by the UE 602 and transmitted in an uplink message from the UE 602 to the network entity 604. In some examples, the network entity 604 may be configured to determine estimated velocity7information for the UE 602, where the network entity 604 may perform the velocity7estimation for UE 602 with or without receiving the velocity7indication 614 or other UE-based estimated velocity information from the UE 602. In some aspects, the velocity estimation process at the UE 602 (e. / g., velocity estimation 612) and / or the velocity evaluation for the UE that is performed by the network entity 604 can be implemented as semi-persistent information that is updated at a periodic or aperiodic rate. In some cases, the velocity7estimation 612 can be performed before the OOK configuration 615 is received by the UE 602, and may also be performed one or more additional times after the OOK configuration 615 is received. The corresponding velocity indication 614 for each subsequent instance of the velocity estimation 612 performed after the OOK configuration 615 is received may be signaled from the UE 602 to the network entity 604, and / or may be signaled when the new velocity estimate has changed by at least a threshold amount or percentage, etc.

[0129] Subsequent to the transmission of OOK configuration 615, the network entity 604 transmits a CSI-RS 631. The CSI-RS 631 can be transmitted corresponding to a configured and / or scheduled measurement occasion for periodic or aperiodic CSI reporting by the UE 602. The UE 602 can obtain channel measurement information corresponding to the CSI-RS 631, and can generate the corresponding CSI report for the CSI-RS 631.

[0130] At block 632, the UE 602 can evaluate the CSI report 632 against one or more previous CSI reports generated and / or transmitted by the UE 602 to the network entity7604. For example, the systems and techniques can be configured to provide the OOK waveform for CSI report transmission where the OOK configuration 615 causes the UE 602 to determine difference information between the generated CSI report 632 and a previous CSI report generated by the UE at an earlier time and for the same channel as the generated CSI report 632. In an illustrative example, the evaluation of the generated CSI report at block 632 can correspond to the UE 602 determining difference informationPATENTQualcomm Docket No 250104WO46between the current (e.g., generated but not yet transmitted) CSI report and an earlier (e.g., previously generated and transmitted) CSI report, in accordance with some examples.

[0131] For example, in some aspects, the OOK configuration 615 and corresponding OOK waveform for CSI report transmission can be implemented to cause the UE 602 to transmit a CSI report (e.g., the generated CSI report 632 corresponding to the measurement information of CSI-RS 631) only if the generated CSI report 632 carries a different information than the previous CSI report. For example, the OOK configuration 6615 can cause the UE 602 to transmit a generated CSI report only if the UE 602 determines that the generated CSI report carries measurement information that is different from the measurement information carried in the last CSI report that was most recently transmitted by the UE 602 to the same network entity 604. If the currently generated CSI report does not carry different information from the previously transmitted CSI report, the UE 602 can use discontinuous transmission (DTX) to skip transmitting the generated CSI report to the network entity 604.

[0132] For example, based on having received the OOK configuration 615, at block 632, the UE 602 may evaluate the generated CSI report 632 corresponding to CSI-RS 631 by comparing the generated CSI report 632 with a previous CSI report corresponding to the channel. The generated CSI report 632 can correspond to a first time and / or a first CSI-RS (e.g., CSI-RS 631), and the previous CSI report can be a last (e.g., most recently, previously, etc.) transmitted CSI report generated by the UE 602 corresponding to a second time and / or a second CSI-RS. The second time associated with the previous transmitted CSI report is earlier than (e.g., before) the first time associated with the generated CSI report 632. The second CSI-RS associated with the previous transmitted CSI report is earlier than (e.g., before) the CSI-RS 631 associated with the generated CSI report 632.

[0133] Evaluating the CSI report 632 can be based on comparing the generated CSI report 632 and the previous transmitted CSI report to determine, from the comparison, if the CSI reports are the same. For example, the generated CSI report 632 may be evaluated to be the same as the previous transmitted CSI report based on both CSI reports including or carry ing the same channel measurement information, the same values, the same CSF, etc.PATENTQualcomm Docket No 250104WO47

[0134] In an illustrative example, at block 634, the UE 602 can determine that the generated CSI report 632 is the same as the earlier, last / most recently transmitted CSI report from the UE 602 to the network entity 604. Based on determining at block 634 that the currently generated CSI report 632 is the same as the last transmitted CSI report, the UE 602 can determine at block 636 to skip transmission of the generated CSIU report 632.

[0135] The UE 602 can implement or configure non-transmission of the generated CSI report 632 using DTX, which may be configured, enabled, activated, etc., at block 636 corresponding to the determination to skip the transmission of the generated CSI report 632, according to the OOK configuration 615.

[0136] The generated CSI report 632 can be associated with a scheduled PUCCH transmission on a set of configured time / frequency resources indicated from the network entity 604 to the UE 602 in either an aperiodic CSI report request, or in a configuration for periodic CSI reporting, based on if the generated CSI report 632 is an aperiodic or periodic CSI report type. Based on the network entity 604 providing the UE 602 with the CSI reporting configuration previously, the network entity 604 can perform DTX detection 637 to determine whether the UE 602 transmits the generated CSI report 632 for the CSI-RS 631 (e.g., comprising a first feedback type according to the OOK configuration 6154), or to otherwise detect that the UE 602 has not transmitted a CSI report corresponding to the CSI-RS 631.

[0137] For example, DTX detection 637 can be based on the network entity 604 monitoring for an uplink signal or transmission on the scheduled time / frequency resources allocated for the PUCCH transmission of an expected CSI report for the CSI-RS 631. If the network entity 604 does not detect an UL transmission above the noise floor on the configured (e.g., allocated and scheduled resources for the CSI report over PUCCH for CSI-RS 631), the network entity 604 can determine, detect, and / or identity7the DTX corresponding to the non-transmission of the generated CSI report 632 by the UE 602. Based on the OOK configuration 615, the network entity 604 can interpret the detected DTX (e.g., non-transmission of the generated CSI report 632) as an indication from the UE 602 signaling that the currently generated CSI report 632 for the CSI-RS 6531 was the same as the last transmitted CSI report from the UE 602 to the network entity 604. The network entity 604 can be configured to reuse the measurementPATENTQualcomm Docket No 250104WO48information from the last transmitted CSI report (e.g., most recently received CSI report at the network entity' 604 from the UE 602) as the measurement information for the expected CSI report for CSI-RS 631. The reuse of the last transmitted CSI report can be based on the OOK configuration 615 where non-transmission of a CSI report during a scheduled PUCCH by the UE 602, and corresponding DTX detection on the scheduled PUCCH by the network entity 604, implicitly indicates that the expected CSI report on the scheduled PUCCH can be obtained by reusing the last CSI report transmitted from the UE 602 to the network entity 604.

[0138] Subsequently, for a next or later CSI-RS 641 transmitted by the network entity 604, the UE 602 can perform measurements of the CSI-RS 641 to generate and evaluate a CSI report 642 for the next CSI report occasion. The CSI-RS 641 and evaluation of the corresponding generated CSI report 642 by the UE 602 can be the same as, similar to, and / or can correspond to the CSI-RS 631 and the evaluation of the corresponding generated CSI report 632 (respectively) by the UE 602. The evaluation of the generated CSI report 642 can comprise a comparison betw een the generated CSI report 642 and the last (e.g., most recently) transmitted CSI report of the UE 602. While CSI report 632 was not transmitted (e.g., based on being the same as a previous report, determined at block 634), the CSI report 632 is the same as the last CSI report that was transmitted by the UE 602, and can be used in at least some examples as the previous CSI report for the comparison of evaluation 642, and / or the UE 602 can compare the generated CSI report 642 to the same, previously transmitted CSI report that was used for the comparison with the generated CSI report 632.

[0139] At block 642, the UE 602 can determine that the generated CSI report 642. generated for CSI-RS 641, is different than the previous CSI report (e.g., the earlier generated CSI report 632, etc.). The determined difference at block 644 can comprise a difference in one or more measured values for the channel, or other difference in the CSF or measurement information carried by the generated CSI report 642 and the generated CSI report 632. In some cases, the determined difference at block 644 is a determination that the two CSI reports do not cany7identical measurement information.

[0140] Based on determining, from the comparison at block 642, that the currently generated CSI report 642 is not the same as the previous CSI report 632, at block 644 thePATENTQualcomm Docket No 250104WO49UE 602 can determine that the currently generated CSI report 642 should be transmitted to the network entity 6043 according to the OOK configuration 615.

[0141] The UE 602 can perform the CSI report transmission 646 for the generated CSI report corresponding to the CSI-RS 641 at the scheduled time and frequency for the scheduled PUCCH transmission associated with the CSI reporting for CSI-RS 641 (e.g., CSI report transmission 646 can be performed using the expected time and frequency resources configured and / or allocated by the network entity 604).

[0142] As noted above, low velocity scenarios of a UE can correspond to steady and slowly changing channel conditions, based on low velocity of the UE corresponding to low relative velocity between the UE and the network entity (e.g., which is often a fixed or stationary base station, gNB, etc.), and the low relative velocity corresponding to more stable channel conditions. In some cases, low velocity7scenarios of the UE may correspond to multiple consecutive CSI reports being generated by the UE (e.g., at a configured periodic CSI report measurement period, and / or in response to aperiodic CSI report requests, etc.) that carry the same (e.g., identical, equal, etc.) information of the channel and / or channel conditions.

[0143] In some aspects, the OOK configuration implemented by the systems and techniques can save a large amount of PUCCH transmissions from being performed by the UE. based on the UE skipping scheduled PUCCH transmissions for a CSI report that the UE has generated and evaluated to identify as being identical to a previously transmitted CSI report. The OOK configuration and / or OOK waveform for CSI report transmission by a UE can provide UE power saving to reduce the power consumption associated with RF transmissions and / or reception by the UE. For example, the UE power saving can be based on the non-transmission of duplicate CSI reports according to the OOK configuration (e.g., the portion of the OOK waveform using the absence of a signal to indicate information). The UE power saving can be based on performing fewer uplink transmissions by the UE not performing the PUCCH transmission for CSI reports that are the same as a previous CSI report (e.g.. corresponding to the CSI report transmission). The UE power saving may also be referred to as UL power saving and / or UL power reduction for the UE.

[0144] In some examples, the OOK configuration and / or OOK waveform for CSI report transmission based on comparing a generated CSI report of the UE with a previous CSIPATENTQualcomm Docket No 250104WO50report of the UE (e.g., a recently transmitted CSI report, a previously transmitted CSI report, a last transmitted CSI report, etc.) can be used to provide reduced interference on the wireless network. For example, reducing the number of UL transmissions from the UE (e.g., by non-transmission of duplicate or identical CSI reports in low velocity scenarios) can reduce the inter-UE uplink interference for multiplexed PUCCH over the same time / frequency resources of the network. In another example, the reduced UL transmissions corresponding to using the OOK configuration and OOK waveform to cause the UE to skip duplicate CSI report transmission can be used to reduce the crosscell UE UL interference within the wireless network.

[0145] In some cases, the network entity 604 can signal to the UE 602 an indication to enable the OOK configuration 615. In some cases, the network entity 604 can signal to the UE 602 an indication to disable the OOK configuration 615. The indication to enable and / or the indication to disable the OOK configuration 615 can be based on the UE velocity, which may be evaluated by the network entity 604, and / or signaled by the UE 602 (e.g., according to a velocity estimation 612, etc.). In some aspects, the network entity can signal to the UE an indication whether the OOK configuration 615 applies for only- periodic CSI reports, or for both periodic and aperiodic CSI reports (e.g., in examples where the aperiodic CSI report format is identical or different from the periodic CSI report format, etc.).

[0146] In some aspects, the network entity’ 604 can configure the UE 602 to transmit a generated CSI report even if the generated CSI report is identical to a previous CSI report, based on the expiration of a configured timeout for a timer starting at the time of the last transmitted CSI report from the UE to the network entity. For example, instead of using DTX for non-transmission of the generated CSI report, the expiration of the configured timeout can override the underlying default OOK configuration 615 to cause the UE to transmit the generated CSI report at least every interval of time given by the configured timeout (e.g.. if the configured timeout is 100ms the UE will transmit CSI reports with a gap of no more than 100ms between consecutive transmitted CSI reports).

[0147] For example, FIG. 7 is a call flow diagram illustrating an example processing flow 700 for a UE 702 and a network entity 704, where the UE 702 is configured to perform CSI reporting based on difference information between a current CSI report and an earlier CSI report and further using a configured timeout interval Timeout 790, inPATENTQualcomm Docket No 250104WO51accordance with some examples. In some aspects, the UE 702 can be the same as the UE 602 of FIG. 6, and the network entity 704 can be the same as the network entity 604 of FIG. 6.

[0148] The network entity 704 can transmit an OOK configuration 715, which can correspond to the OOK configuration 615 of FIG. 6, and may be extended to include an indication of the configured timeout 790 timer Ttimeout length and / or timer value for the configured timeout 790 Ttimeout, etc.

[0149] A CSI-RS 721 can correspond to one or more of the CSI-RS 631 and / or the CSI-RS 641 of FIG. 6. The UE 702 can generate and evaluate a generated CSI report 722, the same as or similar to the UE 602 generating and evaluating the generated CSI report 632 of FIG. 6

[0150] At block 724, the UE 702 can determine the generated CSI report 722 is not the same as (e.g., is different from) an earlier transmitted CSI report. Block 724 can be the same as or similar to the determination at block 644 of FIG. 6. In response, the UE 702 performs CSI report transmission 726 for the generated CSI report 722, which may be the same as or similar to the UE 602 performing CSI report transmission 646 for the generated CSI report 642 of FIG. 6.

[0151] Based on the OOK configuration 715 including an indication of the configured timeout Ttimeout 790. the UE 702 can start (or restart) a timer corresponding to the configured timeout Ttimeout 790. For example, a timer for the configured timeout length 790 can be started or restarted at each transmission of a CSI report by the UE 702 to the network entity 704. The start time for the timer can be the transmission time of the CSI report. The elapsed time or duration of the timer can be equal to the length or value indicated by the OOK configuration 715 for the Ttimeout 790.

[0152] The network entity 704 can transmit a next (e.g., later, subsequent, etc.) CSI-RS 731. The CSI-RS 731 can correspond to one or more of the CSI-Rs 631 and / or the CSI-RS 641 of FIG. 6.

[0153] The UE 702 can generate and evaluate a generated CSI report 732 corresponding to the CSI-RS 731, the same as or similar to the UE 702 generating and evaluating the generated CSI report 722, and / or the UE 602 generating and evaluating the generated CSIPATENTQualcomm Docket No 250104WO52report 632 of FIG. 6, and / or the UE 602 generating and evaluating the generated CSI report 642 of FIG. 6, etc.

[0154] At block 734, the UE 702 can determine the generated CSI report 732 is the same as the previous transmitted CSI report (e.g., the generated CSI report 722, transmitted as the CSI report transmission 726), and may skip transmission of the generated CSI report 732 (e.g., DTX, non-transmission for the generated CSI report 732, etc.). In one illustrative example, the UE 702 can additionally determine at block 734 that the configured timeout Ttimeout 790 has not yet expired. Based on the elapsed time from the last CSI report transmission 726 being less than the configured timeout Ttimeout 790. the UE 702 may proceed with the DTX for non-transmission of the generated CSI report 732.

[0155] At block 737, the network entity 704 can perform DTX detection corresponding to the expected CSI report for the CSI-RS 731, the same as or similar to the DTX detection of block 637 performed by the network entity 604 of FIG. 6 corresponding to the expected CSI report for the CSI-RS 631 of FIG. 6.

[0156] Based on the DTX detection 737, the network entity 704 determines the OOK-based implicit signaling that the generated CSI report 732 for CSI-RS 731 is the same as the last CSI report transmission 726, and at block 739 the network entity 704 reuses the last transmitted CSI report 726 as the CSI report expected for the CSI-RS 731 (e.g.. the same as, similar to, and / or corresponding to the CSI report reuse at block 639 of FIG. 6).

[0157] The network entity 704 can transmit a next (e g., later, subsequent, etc.) CSI-RS 741. The CSI-RS 741 can correspond to one or more of the CSI-RS 631 and / or the CSI-RS 641 of FIG. 6.

[0158] The UE 702 can generate and evaluate a generated CSI report 742 corresponding to the CSI-RS 741, the same as or similar to the UE 702 generating and evaluating the generated CSI report 722, and / or the UE 702 generating and evaluating the generated CSI report 732, and / or the UE 602 generating and evaluating the generated CSI report 632 of FIG. 6, and / or the UE 602 generating and evaluating the generated CSI report 642 of FIG.6. etc.

[0159] At block 744, the UE 702 can determine based on the comparison between the generated CSI report 742 and the previous CSI report 732 (e.g., which is the same as thePATENTQualcomm Docket No 250104WO53earlier CSI report 722 comprising the last CSI report transmission 726) that the CSI report 742 is the same as the previous CSI report 732 and the last transmitted CSI report 726.

[0160] In one illustrative example, at block 744, the UE 702 can additionally determine that the configured timeout Ttimeout 790 has expired and that the generated CSI report 732 cannot or should not be skipped or held for DTX non-transmission due to the expiration of the configured timeout Ttimeout 790. In some aspects, the UE 702 can compare the configured timeout length from the OOK configuration 715 (e.g., the timeout length Ttimeout) with an elapsed time from the start of the timer 790 (e.g., at the transmission time of the last CSI report transmission 726) to the current time (e.g., current time at the evaluation performed in block 744). In some aspects, the UE 702 is configured to determine the elapsed time from the start of the timer 790 to the future, scheduled transmission time corresponding to the generated CSI report 742 (e.g., the future, scheduled transmission time where the network entity 704 expects the CSI report corresponding to the CSI-RS 741).

[0161] At block 744, the UE 702 can determine that the elapsed time from the last CSI report transmission 726 to either the current time (of block 744) and / or to the future, scheduled transmission time for the CSI report transmission (e.g., at 746) is longer than the configured timeout length Ttimeout, and therefore that the timer 790 has (or will) expire. Based on the expiration of the timer 790, the UE 702 determines that the generated CSI report 742 should not be skipped and held for non-transmission, due to the elapsed time since the last CSI report transmission 726. Based on the expiration of timer 790, the UE performs CSI report transmission 746 for the generated CSI report 742, which can be identical to the earlier CSI report 734 and otherwise skippable if the timer 790 was not expired.

[0162] FIG. 8 is a flowchart diagram illustrating an example of a process 800 for wireless communications. In some aspects, the process 800 can be a process for wireless communications by a network entity (e.g., aUE, etc.). For example, the process 800 can be a process for wireless communications by a UE. In some examples, the process 800 can be performed by a network entity or network device (or apparatus) or a component (e.g., a chipset, codec, etc.) of the network entity or device. The process 800 can be performed by one or more processors such as one or more CPUs, DSPs, NPUs, NSPs, microcontrollers. ASICs. FPGAs, programmable logic devices, discrete gates or transistorPATENTQualcomm Docket No 250104WO54logic components, discrete hardware components, etc., any combination thereof, and / or other component or system) of the network entity or device or apparatus. The operations of the process 800 may be implemented as software components that are executed and run on one or more processors (e.g., processor 910 and / or processing system 902 of FIG.9, or other processor(s)).

[0163] In some examples, the process 800 can be performed by a UE, including any of the various UEs described herein. In some aspects, the process 800 can be performed by a UE. smartphone, mobile computing device, user computer device, etc. The process 800 can be performed by a component or system (e.g., a chipset) of a network device (e.g.. one or more of UEs 104, 152, 164, 182, 190 of FIG. 1; UE 104 of FIG. 2; UE(s) 104 of FIG. 3; wireless device 407 of FIG. 4; computing system 900 and / or processing system 902 of FIG. 9; etc.). The network device may be a mobile device (e.g., a mobile phone), a network-connected wearable such as a watch, an extended reality (XR) device such as a virtual reality (VR) device or augmented reality (AR) device, a vehicle or component or system of a vehicle, or other type of computing device. The operations of the process 800 may be implemented as software components that are executed and run on one or more processors (e.g., the transmit processor 264, the receive processor 258, the TX MIMO processor 266, the MIMO detector 256 of FIG. 2, the processing system 470 of FIG. 4, the processor(s) 484 of FIG. 4, the processing system 902 of FIG. 9, and / or the processor 910 of FIG. 9, or other processor(s) (e.g., such as one or more other processors included within and / or associated with the processing system 470 of FIG. 4, the processing system 902 of FIG. 9, etc.). Further, the transmission and reception of signals by the network entity in the process 800 may be enabled, for example, by one or more antennas, one or more transceivers (e.g., wireless transceiver(s)), and / or other communication components (e.g., the transmit processor 264, the receive processor 258, the TX MIMO processor 266, the MIMO detector 256, the modulator(s) / demodulator(s) 254a through 254t, and / or the antenna(es) 252a through 252t of FIG. 2, the antenna(es) 487 of FIG. 4, the wireless transceiver(s) 478 of FIG. 4, the communication interface 940 of FIG. 9, or other antennae(s), transceiver(s), and / or component(s)).

[0164] At block 802, the network device (or component thereof) can receive, from a network entity, an on-off keying (OOK) configuration for channel state information (CSI) feedback by the network device. For example, the network device associated withPATENTQualcomm Docket No 250104WO55performing the process 800 may correspond to one or more of the UEs of FIGS. 1-7, etc. In some cases, the network device can correspond to the UE 104 of FIG. 5A and / or the UE 504 of FIG. 5B, and the network entity can correspond to the network entity 102 of FIG. 5A and / or the network entity 502 of FIG. 5B. In some cases, the network device can correspond to the UE 602 of FIG. 6 and the network entity can correspond to the network entity' 604 of FIG. 6. In another example, the network device can correspond to the UE 702 of FIG. 7, and the network entity' can correspond to the network entity 704 of FIG. 7.

[0165] In some examples, the CSI feedback by the network device can correspond to the channel estimation(s) 508 and / or the CSI report 510 of the UE 504 of FIG. 5B. In some cases, the CSI feedback by the network device can correspond to feedback associated with one or more of the CSI-RS 631, the CSI-RS 641, etc., of FIG. 6, and / or the CSI-RS 721, the CSI-RS 731, and / or the CSI-RS 741 of FIG. 7, etc. In some cases, the OOK configuration can correspond to the OOK configuration 615 of FIG. 6 and / or the OOK configuration 715 of FIG. 7, etc.

[0166] In some examples, the network device (or component thereof) can be configured to determine estimated velocity information corresponding to the network device, and transmit the estimated velocity information to the network entity. For example, the estimated velocity information can be determined corresponding to the velocity estimation 612 of FIG. 6, and the estimated velocity information transmitted to the network entity can correspond to the velocity indication 614 of FIG. 6. In some examples, the OOK configuration received from the network entity based on the estimated velocity' information can be the OOK configuration 615 received from network entity 6704 by UE 602 based on the velocity indication 614 of FIG. 6.

[0167] In some cases, the OOK configuration can be disabled based on a determination indicating a velocity of the network device is faster than a threshold velocity. For example, the OOK configuration 615 may be disabled based on a determination that the velocity of the UE 602 (e.g., based on velocity estimation 612 and / or corresponding to the velocity indication 614) is faster than (e.g.. greater than) a configured velocity threshold. In some examples, the OOK configuration is enabled based on a determination indicating a velocity of the network device is slower than a threshold velocity. For example, the OOK configuration 615 may be enabled based on a determination that the velocity of the UEPATENTQualcomm Docket No 250104WO56602 (e.g., based on velocity estimation 612 and / or corresponding to the velocity indication 614) is slower than (e.g., less than) a configured velocity' threshold.

[0168] In some examples, the OOK configuration corresponds to CSI feedback associated with periodic CSI reports by the network device. For example, the OOK configuration 615 of FIG. 6 can correspond to CSI feedback associated with one or more periodic CSI reports for the CSI-RS 631 and / or the CSI-RS 641, etc. (e.g., one or more of a CSI report 632, CSI report 644, transmitted CSI report 646, etc.). In some cases, the OOK configuration 715 of FIG. 7 can correspond to CSI feedback associated with periodic CSI reports, corresponding to one or more of the CSI-RS 721. the CSI-RS 731. and / or the CSI-RS 741 of FIG. 7, etc. In some examples, the OOK configuration corresponds to CSI feedback associated with periodic CSI reports and aperiodic CSI reports by the network device.

[0169] In some cases, the OOK configuration is indicative of a configured timeout length for non-transmission of one or more CSI reports including the generated CSI report. For example, the configured timeout length can correspond to the timeout Ttimeout 790 of FIG. 7, and may be indicated based on the OOK configuration 715 of FIG. 7, etc. In some examples, the configured timeout length is a maximum elapsed time for discontinuous transmission (DTX) of scheduled physical uplink control channel (PUCCH) transmissions corresponding to CSI reports by the network device.

[0170] In some cases, the netw ork device (or component thereof) can determine a start time as a transmission time of the previous CSI report, and can determine an elapsed time as a difference between a scheduled transmission time of a physical uplink control channel (PUCCH) for the generated CSI report, and the start time. The network device (or component thereol) can perform the transmission of the generated CSI report in response to a determination the elapsed time is greater than the configured timeout length. For example, the UE 702 may transmit the generated CSI report 746 in response to a determination that an elapsed time from a start time corresponding to the CSI report transmission 726 is greater than the configured timeout length Ttimeout 790. In some cases, the network device (or component thereof) may be configured to perform the transmission or the non-transmission of the generated CSI report according to the comparison, in response to a determination the elapsed time is less than the configured timeout length.PATENTQualcomm Docket No 250104WO57

[0171] At block 804, the network device (or component thereof) can generate a CSI report corresponding to a channel between the network device and the network entity7, wherein the generated CSI report is associated with a first time.

[0172] For example, the CSI report can be the same as or similar to one or more of the CSI report 510 of FIG. 5, associated with the channel estimation 508 for CSI-RS 506. The CSI report can be the same as or similar to the CSI report evaluated at 632 of FIG. 6, the CSI report evaluated at 642 of FIG. 6, and / or the CSI report 646 of FIG. 6, etc. The CSI report can be the same as or similar to the CSI report evaluated at 722 of FIG. 7, the CSI report 726 of FIG. 7, the CSI report evaluated at 732 of FIG. 7, the CSI report evaluated at 742 of FIG. 7, and / or the CSI report 746 of FIG. 7, etc.

[0173] At block 806, the network device (or component thereof) can compare the generated CSI report with a previous CSI report corresponding to the channel, the previous CSI report associated with a second time that is before the first time, and wherein the comparison is based on the OOK configuration. For example, comparing the generated CSI report with a previous CSI report can correspond to the evaluation of CSI report 632 of FIG. 6 and / or the evaluation of CSI report 642 of FIG. 6, and / or the evaluation of CSI report 722 of FIG. 7, and / or the evaluation of CSI report 732 of FIG. 7, and / or the evaluation of CSI report 742 of FIG. 7, etc.

[0174] At block 808. the network device (or component thereof) can signal a corresponding CSI feedback to the network entity indicative of the generated CSI report, wherein the corresponding CSI feedback is signaled to the network entity by transmission or non-transmission of the generated CSI report according to the comparison.

[0175] For example, the corresponding CSI feedback can comprise the transmission of the generated CSI report in response to the comparison indicating one or more differences between the generated CSI report and the previous CSI report. For example, transmission of the generated CSI report in response to the comparison can correspond to one or more of the CSI report transmission 646 of FIG. 6, the CSI report transmission 726 of FIG. 7, and / or the CSI report transmission 746 of FIG. 7, etc.

[0176] In another example, the corresponding CSI feedback can comprise the nontransmission of the generated CSI report in response to the comparison indicating the generated CSI report is the same as the previous CSI report. For example, the non-PATENTQualcomm Docket No 250104WO58transmission of the generated CSI report in response to the comparison can correspond to one or more of the non-transmission for evaluated CSI report 632 of FIG. 6 (e.g., skipped CSI report 636) and / or the non-transmission for evaluated CSI report 732 of FIG. 7 (e.g., skipped CSI report 734), etc.

[0177] In some cases, the generated CSI report is the same as the previous CSI report, based on the generated CSI report and the previous CSI report including identical measurement information of the channel. In some examples, the network device (or component thereof) can be configured to perform non-transmission of the generated CSI report by using discontinuous transmission (DTX) for a physical uplink control channel (PUCCH) scheduled for the generated CSI report. In some cases, the corresponding CSI feedback comprises the DTX during a scheduled time of the PUCCH, and detection of the DTX comprises an indication the generated CSI report is equal to the previous CSI report. In some examples, the corresponding CSI feedback comprising the DTX during a scheduled time of the PUCCH is configured to cause the network entity to reuse information of the previous CSI report.

[0178] In some examples, the processes described herein (e.g., process 800 and / or other process described herein) may be performed by a computing device or apparatus (e.g., a network node such as a UE, base station, a portion of a base station, etc.).

[0203] Where components are described as being ‘'configured to” perform certain operations, such configuration may be accomplished, for example, by designing electronic circuits or other hardware to perform the operation, by programming programmable electronic circuits (e.g.. microprocessors, or other suitable electronic circuits) to perform the operation, or any combination thereof.

[0204] The phrase ‘'coupled to” or “communicatively coupled to” refers to any component that is physically connected to another component either directly or indirectly, and / or any component that is in communication with another component (e.g., connected to the other component over a wired or wireless connection, and / or other suitable communication interface) either directly or indirectly.

[0205] Claim language or other language reciting '‘at least one of’ a set and / or '‘one or more” of a set indicates that one member of the set or multiple members of the set (in any combination) satisfy the claim. For example, claim language reciting “at least one of A and B” or “at least one of A or B” means A, B, or A and B. In another example, claim language reciting “at least one of A, B. and C” or “at least one of A, B, or C” means A, B. C, or A and B, or A and C, or B and C, A and B and C, or any duplicate information or data (e.g., A and A, B and B, C and C, A and A and B, and so on), or any other ordering, duplication, or combination of A, B, and C. The language “at least one of’ a set and / or “one or more” of a set does not limit the set to the items listed in the set. For example, claim language reciting “at least one of A and B” or “at least one of A or B” may mean A, B, or A and B, and may additionally include items not listed in the set of A and B.

[0206] Claim language or other language reciting “at least one processor configured to,” “at least one processor being configured to,” or the like indicates that one processor or multiple processors (in any combination) can perform the associated operation(s).
