[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 029,014, filed May 22, 2020, entitled “INDICATIONS OF APOWER AMPLIFIER NONLINEARITY STATE,” and U.S. Non-Provisional Patent Application No. 17 / 325,663, filed May 20, 2021, entitled “INDICATIONS OF A POWER AMPLIFIER NONLINEARITY STATE,” which are expressly incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to wireless communication and techniques and apparatus for indicating the nonlinear state of a power amplifier. Background Technology

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

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

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a universal protocol enabling different user equipment to communicate at the city, country, region, and even global levels. NR, also known as 5G, is an enhancement set of the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0032] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or a method may be implemented using any number of the aspects set forth herein.

It should be understood that any aspect of this disclosure may be implemented by one or more elements of the claims.

[0033] Several aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in the “Detailed Description” section and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0034] It should be noted that while the terms commonly associated with 5G or NR radio access technology (RAT) may be used to describe the aspects herein, the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0035] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among other examples. Wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, Transmit / Receive Point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0036] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or other types of cells. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and allow restricted access for UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0037] In some respects, the cell may not be fixed, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0038] The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0039] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs), such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0040] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. The BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0042] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with base stations, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to or to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0044] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0045] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band with a second frequency range (FR2), which can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, FR2 is often referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise explicitly stated, it should be understood that the terms "below 6 GHz," etc., if used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the terms "millimeter wave," etc., if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate band frequencies (e.g., less than 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0046] As mentioned above, providing Figure 1 As an example. Other examples can be related to... Figure 1 The examples described are different.

[0047] Figure 2 This is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T≥1 and R≥1.

[0048] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and decoding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (when needed), and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0049] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator can further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if necessary), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoding control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, among others. In some respects, one or more components of the UE 120 may be contained within a housing.

[0050] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0051] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as... Figure 2 One or more components.

[0052] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 can be pre-encoded by the TX MIMO processor 266 as needed, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator of UE 120 (e.g., MOD / DEMOD 254) can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264 and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform the functions described herein (e.g., as referenced). Figures 3 to 8 Any aspect of any method described herein.

[0053] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 when necessary, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform the functions described herein (e.g., as referenced).

[0054] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2Any other component may perform one or more techniques associated with the indication of the nonlinear state of the power amplifier, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can execute or direct, for example Figure 5 Process 500 Figure 6 Process 600 Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, transformation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example...

Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0056] In some aspects, the first wireless communication device (e.g., base station 110, UE 120, and / or similar device) may include components for transmitting an indication of a power amplifier nonlinearity state for transmitting communication to the second wireless communication device; components for transmitting communication to the second wireless communication device at least in part based on the power amplifier nonlinearity state; and / or similar components. In some aspects, the first wireless communication device (e.g., base station 110, UE 120, and / or similar device) may include components for transmitting an indication of a power amplifier nonlinearity state for transmitting communication to the first wireless communication device to the second wireless communication device; components for estimating the nonlinearity of communication at least in part based on the indication of the power amplifier nonlinearity state; and / or similar components. In some aspects, such components may include combinations of... Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0057] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to these boxes can be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of controller / processor 280.

[0058] As mentioned above, providing Figure 2 As an example. Other examples can be related to... Figure 2 The examples described are different.

[0059] In some wireless communication devices, such as UEs or base stations, nonlinear components, such as high-power amplifiers with a limited linear dynamic range, may be used. This can cause transmission distortion, at least in part, based on a relatively high peak-to-average power ratio (PAPR). Nonlinear distortion can be categorized into in-band distortion, which can affect link performance, and / or out-of-band distortion, which is associated with interference from adjacent channels.

[0060] To reduce in-band and / or out-of-band distortion, power backoff can be used to reduce the amount of transmitted power. However, power backoff may reduce the power efficiency of the transmission. Additionally or alternatively, wireless communication devices may use a digital predistorter (DPD) in a decision feedback equalizer (DFE) to reduce distortion. However, wireless communication devices with multiple transmission elements at each port may encounter difficulties in implementing DPD at each transmission element or each port of the wireless communication device.

[0061] In some networks, receiving wireless communication devices can estimate nonlinearities and / or use digital post-distortion (DPOD) to reduce or correct the amount of distortion caused by the received transmission. In some networks, the receiving wireless communication device can estimate nonlinearities and / or perform over-the-air DPD training of a nonlinear transmission array by providing feedback (e.g., an indication of the estimated nonlinearity).

[0062] However, the receiving wireless communication device may not be able to receive a sufficient number of pilots from the transmitting wireless communication device's transmission to accurately (e.g., with threshold accuracy) estimate nonlinearity. This may cause the transmitting wireless communication device to use an increased amount of power backoff to adequately reduce the distortion caused by the transmitting wireless communication device's transmission. This may reduce the power efficiency of the transmission, which could reduce the power efficiency of the transmitting wireless communication device and consume power resources. Transmitting with a sufficient number of pilots within the transmitting wireless communication device's transmission, at least in part due to the increased overhead of the transmission, may consume network and / or communication resources.

[0063] In some aspects described herein, a receiving wireless communication device can be aware of the power amplifier nonlinearity state associated with a transmission by a transmitting wireless communication device. For example, the transmitting wireless communication device can indicate to the receiving wireless communication device the power amplifier nonlinearity state used for one or more transmissions. In some aspects, the receiving wireless communication device can indicate to the transmitting wireless communication device the power amplifier nonlinearity state used for transmitting communications.

[0064] Based at least in part on the fact that the receiving wireless communication device knows the power amplifier nonlinearity state associated with the transmission of the transmitting wireless communication device, the receiving wireless communication device can estimate the nonlinearity of the communication transmitted by the transmitting wireless communication device using pilot measurements from previous transmissions that utilized the same power amplifier nonlinearity state. In this way, the receiving wireless communication device can accurately estimate the nonlinearity of the transmission from the transmitting wireless communication device using a reduced number of pilots in a single transmission. This can save power resources that might otherwise be lost due to increased power inefficiency caused by power backoff, and / or save communication and network resources that might otherwise be used to transmit additional pilots.

[0065] Figure 3 This is a diagram illustrating example 300 associated with an indication of the nonlinear state of a power amplifier according to this disclosure. Figure 3 As shown, a UE (e.g., UE 120) can communicate with a base station (e.g., base station 110). The UE and the base station can be part of a wireless network (e.g., wireless network 100).

[0066] As indicated by reference numeral 305, a base station can transmit and a UE can receive configuration information. In some aspects, the UE can receive configuration information from another device (e.g., from another base station, another UE, and / or similar device). In some aspects, the UE can receive configuration information via one or more of Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling (e.g., MAC Control Element (MAC CE)), and / or similar signaling. In some aspects, the configuration information may include indications of one or more configuration parameters (e.g., those already known to the UE) for the UE to select, explicit configuration information for the UE to configure itself, and / or similar information.

[0067] In some aspects, the configuration information may instruct the UE to provide an indication of the power amplifier nonlinearity state for one or more uplink transmissions. In other aspects, the configuration information may instruct the UE to indicate its ability to transmit communications based at least in part on an indication of the power amplifier nonlinearity state (e.g., received from a base station). In other words, the configuration information may include a request for capability information indicating whether the UE can configure itself to transmit communications using the indicated power amplifier nonlinearity state.

[0068] In some aspects, the power amplifier nonlinear states may be at least partially based on or can be identified by one or more metrics, such as the transmission port used for transmitting communications, the transmission beam, the power amplifier gain state, the power amplifier supply voltage state (VCC), and / or similar metrics. In some aspects, the UE may be configured to transmit using a configured number of different power amplifier nonlinear states. Different power amplifier nonlinear states may be associated with corresponding identifiers (e.g., exponents) that can be used to identify the set of metrics.

[0069] In some respects, configuration information can instruct the UE to transmit communication for a single transmission, a specified number of transmissions, a set of transmissions scheduled by a configured authorization, a transmission within a specified time period, a transmission associated with one or more channels, a transmission prior to receiving an indication of a change from the indicated power amplifier nonlinearity state, and / or similar transmissions in the indicated power amplifier nonlinearity state.

[0070] As shown by reference numeral 310 in the accompanying drawings, the UE can be configured to communicate with a base station. In some aspects, the UE can be configured at least partially based on configuration information. In some aspects, the UE can be configured to perform one or more of the operations described herein.

[0071] As indicated by reference numeral 315, the UE may transmit, and the base station may receive, an indication of the UE's ability to communicate based at least in part on an indication of the power amplifier's nonlinear state. For example, the UE may indicate its ability to freeze (e.g., prohibit change) the power amplifier's nonlinear state based at least in part on receiving an indication to freeze the power amplifier's nonlinear state. In some aspects, the UE may indicate its ability to identify a set of parameters for transmitting communications based at least in part on an indication from the base station (e.g., an indication of an identifier associated with a set of parameters). In some aspects, the UE may transmit the indication via RRC signaling, one or more MAC CEs, Physical Uplink Control Channel (PUCCH) messages, and / or the like.

[0072] As indicated by reference numeral 320, the UE can transmit, and the base station can receive, one or more communications, and indicate the power amplifier nonlinearity state of the corresponding communication used to transmit the one or more communications. In some aspects, the UE can transmit one or more pilots within one or more communications that can be used to estimate the nonlinearity associated with different power amplifier nonlinearities. In some aspects, a single transmission may not have a sufficient number of pilots to accurately estimate the nonlinearity of a single transmission (e.g., to meet a threshold accuracy).

[0073] In some respects, combining (e.g., aggregation, averaging, and / or similar methods) a set of one or more communications can provide a sufficient number of pilots to accurately estimate the nonlinearity of the set of one or more communications. Based at least in part on the power amplifier nonlinearity state indicating the transmission of one or more communications, a receiving device (e.g., a base station) may be able to combine sets of one or more communications transmitted with the same power amplifier nonlinearity state to estimate the nonlinearity of communications transmitted with the same power amplifier nonlinearity state.

[0074] As shown by reference numeral 325 in the accompanying drawings, the base station can store power amplifier nonlinearity information of power amplifier nonlinear states. For example, the base station can store information about corresponding communications from the UE (e.g., information from pilots), and can identify this information at least in part based on the indicated power amplifier nonlinear states. In this way, the base station may be able to average the stored information of one or more power amplifier nonlinear states to estimate the nonlinearity of the power amplifier nonlinear states.

[0075] As indicated by reference numeral 330 in the accompanying drawing, the UE can receive, and the base station can transmit, an indication of the power amplifier nonlinearity state that will be used to transmit one or more communications. In some aspects, the indication of the power amplifier nonlinearity state may include a power amplifier (PA) transmission configuration indicator (TCI) state. The PA TCI state can be identified in an indicator of the quasi-co-located (QCL) type.

[0076] In some respects, the UE may receive indications of the power amplifier nonlinearity state via downlink control information (DCI) messages (e.g., dynamic indicators), sidelink control information (SCI) messages (e.g., dynamic indicators from another UE), RRC signaling (e.g., higher-layer indicators, configured authorizations and / or the like), one or more MAC CEs and / or the like.

[0077] In some respects, the indication may include one or more indications associated with the corresponding channel. For example, the indication may include a first indication for the power amplifier nonlinearity state for the PUCCH, a second indication for the Physical Uplink Shared Channel (PUSCH), and / or similar indications.

[0078] In some aspects, the indication of the power amplifier nonlinearity state may include an identifier of the power amplifier nonlinearity state to be used for transmitting communications, an indication that the same power amplifier parameter set will be used for a series of transmissions, a threshold amount of permissible modification of the power amplifier parameter set for a series of transmissions, and / or similar indications. For example, the indication of the power amplifier nonlinearity state may indicate that the UE is allowed to modify the power amplifier parameter set as long as a change to the power amplifier nonlinearity state meets (e.g., is below) a threshold.

[0079] In some aspects, a series of communications includes the transmission of a communication and the transmission of one or more previous communications, the transmission of one or more subsequent communications, and / or the like. In some aspects, the indication of the nonlinear state of the power amplifier may be based at least in part on the number of transmissions to be included in the series of communications, the amount of time to which the transmissions are to be included in the series of communications, and all transmissions and / or similar transmissions for one or more channels prior to receiving additional indication of the nonlinear state of the power amplifier.

[0080] In some respects, the indication of the nonlinear state of the power amplifier can be based at least in part on the same path loss measurement to determine the transmission power of the corresponding transmissions for a series of communications. In other words, the UE can derive the parameters of the corresponding transmissions for a series (e.g., the series indicated by the base station) at least in part on the same reference signal (e.g., the path loss reference signal).

[0081] As indicated by reference numeral 335, the UE can configure a power amplifier nonlinearity state for transmitting one or more communications. In some aspects, the UE can configure one or more components of the transmission chain (e.g., transmit port, transmit processor, TX MIMO processor 266, power amplifier, one or more antennas 252, and / or the like) based at least in part on an indication of the power amplifier nonlinearity state. In some aspects, the UE can configure a transmission port for transmitting communications, a transmission beam for transmitting communications, a power amplifier gain state for transmitting communications, a power amplifier supply voltage state for transmitting communications, and / or similar states. In some aspects, based at least in part on an indication of the power amplifier nonlinearity state, the UE can use the same configuration used for transmitting previous communications (e.g., immediately preceding communications, previous communications identified by the power amplifier nonlinearity state identifier, and / or similar communications).

[0082] As indicated by reference numeral 340 in the accompanying drawings, the UE may transmit one or more communications, which the base station may receive, based at least in part on an indication of the nonlinear state of the power amplifier. In some aspects, the UE may transmit one or more communications with or without any pilots, with and without sufficient pilots that accurately estimate the nonlinearity, and / or similar conditions.

[0083] As indicated by reference numeral 345 in the accompanying drawings, a base station can estimate the nonlinearity of one or more communications. In some aspects, the base station can estimate the nonlinearity of one or more communications (e.g., combined nonlinearity, corresponding nonlinearity, and / or similar nonlinearity) based at least in part on pilot measurements from one or more additional communications transmitted by the UE. For example, the base station can estimate the nonlinearity based at least in part on pilot measurements from one or more previous communications having the same power amplifier nonlinearity state, power amplifier nonlinearity states modified within threshold amounts of one or more communications, and / or similar power amplifier nonlinearity states.

[0084] As indicated by reference numeral 350 in the accompanying drawings, the base station can transmit an indication of estimated nonlinearity for one or more communications. In some aspects, the indication of estimated nonlinearity can identify a power amplifier nonlinearity state associated with the estimated nonlinearity. In some aspects, the indication of estimated nonlinearity can indicate a power amplifier nonlinearity state having a minimum amount of nonlinearity. In some aspects, the indication of estimated nonlinearity can provide estimated nonlinearities for multiple power amplifier nonlinearity states (e.g., as a report). In some aspects, the indication of estimated nonlinearity can cause the UE to perform digital predistortion for subsequent transmissions using the same port as the power amplifier nonlinearity state.

[0085] As shown by reference numeral 355, the base station can perform digital post-distortion correction based at least in part on the nonlinearity of one or more communications estimates.

[0086] Based at least in part on the base station's knowledge of the power amplifier nonlinearity state associated with the UE's transmission, the base station can estimate the nonlinearity of the communication transmitted by the UE using pilot measurements from previous transmissions using the same power amplifier nonlinearity state. In this way, the base station can accurately estimate the nonlinearity of the transmission from the UE using a reduced number of pilots in individual transmissions. This can save power resources that might otherwise be lost due to increased power inefficiency caused by power backoff, and / or save communication and network resources that might otherwise be used to transmit additional pilots.

[0087] As mentioned above, providing Figure 3 As an example. Other examples can be related to... Figure 3 The examples described are different.

Figure 4 As shown, a UE (e.g., UE 120) can communicate with a base station (e.g., base station 110). The UE and the base station can be part of a wireless network (e.g., wireless network 100).

[0089] As indicated by reference numeral 405, the base station can transmit and the UE can receive configuration information. In some aspects, the UE can receive configuration information from another device (e.g., from another base station, another UE, and / or similar device). In some aspects, the UE can receive configuration information via one or more of RRC signaling, MAC signaling (e.g., MAC CE), and / or similar signaling. In some aspects, the configuration information may include indications of one or more configuration parameters (e.g., those already known to the UE) for the UE to select, explicit configuration information for the UE to use in configuring the UE, and / or similar information.

[0090] In some aspects, the configuration information may instruct the UE to estimate the nonlinearity of one or more downlink transmissions, at least in part, based on the power amplifier nonlinearity states indicated by one or more downlink transmissions. For example, the configuration information may instruct the UE to store power amplifier nonlinearity state information used by the base station to transmit one or more power amplifier nonlinearity states for downlink communication. In some aspects, the configuration information may instruct the UE to transmit an indication of its ability to estimate nonlinearity at least in part based on power amplifier nonlinearity states, at least in part based on power amplifier nonlinearity state information combining multiple downlink transmissions, and / or similar information.

[0091] In some respects, configuration information can instruct the UE to receive communication for a single transmission, a specified number of transmissions, a set of transmissions scheduled by a configured license, a transmission within a specified time period, a transmission associated with one or more channels, a transmission prior to receiving an indication of a change from the indicated power amplifier nonlinearity state, and / or similar transmissions in the indicated power amplifier nonlinearity state.

[0092] As indicated by reference numeral 410 in the accompanying drawings, the UE can be configured to communicate with a base station. In some aspects, the UE can be configured at least partially based on configuration information. In some aspects, the UE can be configured to perform one or more of the operations described herein.

In some aspects, the UE may transmit the indication via RRC signaling, one or more MAC CEs, PUCCH messages, and / or similar signaling.

[0094] As indicated by reference numeral 420, the UE may receive, and the base station may transmit, one or more communications with an indication of the power amplifier nonlinearity state for transmitting the corresponding communication in the one or more communications. In some aspects, the base station may transmit one or more pilots within one or more communications that can be used by the UE to estimate nonlinearities associated with different power amplifier nonlinearities. In some aspects, a single transmission may not have a sufficient number of pilots for the UE to accurately (e.g., with accuracy to meet a threshold) estimate the nonlinearity of the single transmission.

[0095] Based at least in part on indications of the nonlinear state of the power amplifier used to transmit one or more communications, the UE may be able to combine sets of one or more communications transmitted in the same power amplifier nonlinear state to estimate the nonlinearity of the communications transmitted in the same power amplifier nonlinear state.

[0096] As shown by reference numeral 425, the UE can store power amplifier nonlinearity information of power amplifier nonlinear states. For example, the UE can store information from corresponding communications from a base station (e.g., information from pilots) and can identify this information at least in part based on the indicated power amplifier nonlinearity state. In this way, the UE may be able to average the stored information of one or more power amplifier nonlinear states to estimate the nonlinearity of the power amplifier nonlinear state.

[0097] As indicated by reference numeral 430, the base station can configure a power amplifier nonlinear state for transmitting one or more communications. In some aspects, the base station can configure one or more components of the transmission chain (e.g., transmit port, transmit processor, TX MIMO processor 230, power amplifier, one or more antennas 234, and / or similar components) based at least in part on the power amplifier nonlinear state. In some aspects, the base station can configure a transmission port for transmitting communications, a transmission beam for transmitting communications, a power amplifier gain state for transmitting communications, a power amplifier supply voltage state for transmitting communications, and / or similar states. In some aspects, based at least in part on the power amplifier nonlinear state, the base station can use the same configuration used for transmitting previous communications (e.g., immediately preceding communications, previous communications identified by the power amplifier nonlinear state identifier, and / or similar communications).

[0098] As indicated by reference numeral 435, the UE may receive, and the base station may transmit, an indication of the power amplifier nonlinearity state for transmitting one or more communications (e.g., one or more previously, currently, or subsequently transmitted communications). In some aspects, the indication of the power amplifier nonlinearity state may include a PA TCI state. The PA TCI state may be identified in a QCL type indicator.

[0099] In some respects, the UE may receive indications of the power amplifier nonlinearity state via DCI messages (e.g., dynamic indicators), SCI messages (e.g., dynamic indicators from another UE), RRC signaling (e.g., higher-level indicators, configured authorizations and / or the like), one or more MAC CEs and / or the like.

[0100] In some respects, the indication may include one or more indications associated with the corresponding channel. For example, the indication may include a first indication for the power amplifier nonlinear state for the Physical Downlink Control Channel (PDCCH), a second indication for the Physical Downlink Shared Channel (PDSCH), and / or similar indications.

[0101] In some aspects, an indication of the nonlinear state of a power amplifier may include an identifier of the nonlinear state of the power amplifier used for transmitting communications, an indication of the same set of power amplifier parameters for a series of communications, an indication of the amount of modification to the set of power amplifier parameters from a previous transmission to be applied to the transmission of the communications (e.g., an indication of satisfying a threshold amount (e.g., an amount less than a threshold)) and / or similar indications.

[0102] In some aspects, a series of communications may include the transmission of the communication and one or more previous communications, one or more subsequent communications, and / or the like.

In some aspects, the base station may transmit one or more communications with or without any pilots, with and without sufficient pilots that accurately estimate the nonlinearity, and / or similar conditions.

[0104] As indicated by reference numeral 445 in the accompanying figure, the UE can estimate the nonlinearity of one or more communications. In some aspects, the UE can estimate the nonlinearity of one or more communications (e.g., combined nonlinearity, corresponding nonlinearity, and / or similar nonlinearity) based at least in part on pilot measurements from one or more additional communications transmitted by the base station. For example, the UE can estimate the nonlinearity based at least in part on pilot measurements from one or more previous communications having the same power amplifier nonlinearity state, power amplifier nonlinearity states modified within threshold amounts of one or more communications, and / or similar power amplifier nonlinearity states.

In this way, the UE can accurately estimate the nonlinearity of the transmission from the base station using a reduced number of pilots in a single transmission. This can save power resources that might otherwise be lost due to increased power inefficiency caused by power backoff, and / or save communication and network resources that might otherwise be used to transmit additional pilots.

Example process 500 is an example in which the first wireless communication device (e.g., base station 110, UE 120, and / or similar device) performs operations associated with an indication of a power amplifier nonlinear state.

[0110] like Figure 5 As shown, in some aspects, process 500 may include receiving an indication of a power amplifier nonlinear state for transmitting communication to a second wireless communication device (block 510). For example, as described above, the first wireless communication device (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receiver processor 238, controller / processor 240, antenna 252, DEMOD 254, MIMO detector 256, receiver processor 258, controller / processor 280 and / or similar components) may receive an indication of a power amplifier nonlinear state for transmitting communication to the second wireless communication device.

[0111] like Figure 5 As further shown, in some aspects, process 500 may include transmitting communication based at least in part on an indication of the nonlinear state of the power amplifier (block 520). For example, as described above, a first wireless communication device (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252 and / or similar components) may transmit communication based at least in part on an indication of the nonlinear state of the power amplifier.
