[0002] This application claims priority to and the benefit of U.S. Patent Application No. 17 / 320,070, filed on May 13, 2021, and U.S. Provisional Patent Application No. 63 / 025,710, filed on May 15, 2020, the entire contents of which are incorporated herein by reference as if fully set forth below and for all applicable purposes. Technical Field

[0003] The present application relates to wireless communication systems, and more particularly to techniques for efficient bandwidth utilization of peak reduction frequency modulation resources.

[0004] introduction

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and 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 enhancement set to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). A wireless multiple access communication system may include several base stations (BSs), each of which simultaneously supports communication of multiple communication devices, which may be referred to as UEs in addition.

[0006] In order to meet the growing demand for extended mobile broadband connectivity, wireless communication technology is progressing from LTE technology to the next generation of new radio (NR) technology, which may be referred to as the fifth generation (5G). For example, NR is designed to provide lower latency, higher bandwidth or higher throughput, and higher reliability compared to LTE. NR is designed to operate over a wide range of frequency bands, such as low-frequency bands below about 1 gigahertz (GHz) and medium-frequency bands from about 1 GHz to about 6 GHz, to high-frequency bands, such as millimeter wave (mmWave) bands. NR is also designed to operate across different spectrum types from licensed spectrum to unlicensed and shared spectrum. Spectrum sharing enables operators to opportunistically aggregate spectrum to dynamically support high-bandwidth services. Spectrum sharing can extend the benefits of NR technology to operating entities that may not have access to licensed spectrum.

[0007] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at city, country, region, and even global levels. NR is designed to better support mobile broadband Internet access by using OFDM with cyclic prefix (CP) (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards.

[0028] Detailed Description

[0029] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. This detailed description includes specific details in order to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0030] The technology described herein can be used for various wireless communication networks, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier FDMA (SC-FDMA) and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network can implement radio technologies such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are new UMTS versions using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization called "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization called "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies and standards are known or under development. For example, the 3rd Generation Partnership Project (3GPP) is a collaboration between various telecommunications association groups that aims to define globally applicable third generation (3G) mobile phone specifications. 3GPP Long Term Evolution (LTE) is a 3GPP project aimed at improving UMTS mobile phone standards. 3GPP can define specifications for next generation mobile networks, mobile systems, and mobile devices. The present disclosure focuses on the evolution of wireless technologies from LTE, 4G, 5G, NR and beyond, which have shared access to wireless spectrum between networks using a collection of new and different radio access technologies or radio air interfaces.

[0031] 5G NR networks envision a variety of deployments, a variety of spectrum, and a variety of services and devices that can be implemented using a unified OFDM-based air interface. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further enhancements to LTE and LTE-A are also being considered. 5G NR will be able to scale to provide coverage for: (1) Ultra-high density (e.g., about 1M nodes / km) 2), ultra-low complexity (e.g., about tens of bits / second), ultra-low energy (e.g., about 10+ years of battery life), and deep coverage capable of reaching challenging locations; (2) mission-critical control including strong security (to protect sensitive personal, financial, or classified information), ultra-high reliability (e.g., about 99.9999% reliability), ultra-low latency (e.g., about 1 ms), and users with a wide range of mobility or lack of mobility; and (3) enhanced mobile broadband including extremely high capacity (e.g., about 10 Tbps / km 2 ), extreme data rates (e.g., multi-Gbps rates, 100+Mbps user experience rates), and deep cognition with advanced discovery and optimization.

[0032] 5G NR can be implemented to: use an optimized OFDM-based waveform with scalable parameter design and transmission time interval (TTI); have a common, flexible framework to use dynamic, low-latency time time division duplex (TDD) / frequency division duplex (FDD) design to efficiently multiplex services and features; and have advanced wireless technologies such as massive multiple input multiple output (MIMO), robust millimeter wave (mmWave) transmission, advanced channel decoding and device-centric mobility. The scalability of parameter design in 5G NR (and the scaling of subcarrier spacing) can efficiently address the operation of diverse services across diverse spectrums and diverse deployments. For example, in various outdoor and macro coverage deployments less than 3GHz FDD / TDD implementations, the subcarrier spacing can occur at 15kHz, such as on bandwidths (BW) such as 5, 10, 20MHz. For other various outdoor and small cell coverage deployments of TDD greater than 3GHz, the subcarrier spacing can occur at 30kHz on 80 / 100MHz BW. For various other indoor broadband implementations, subcarrier spacing may occur at 60kHz over 160MHz BW using TDD on the unlicensed portion of the 5GHz band. Finally, for various deployments transmitting using the mmWave component with TDD at 28GHz, subcarrier spacing may occur at 120kHz over 500MHz BW.

[0033] The scalable parameter design of 5G NR facilitates scalable TTI to meet diverse latency and quality of service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectral efficiency. Efficient multiplexing of long TTIs and short TTIs allows transmissions to start on symbol boundaries. 5G NR also contemplates a self-contained integrated subframe design with UL / downlink scheduling information, data, and acknowledgment in the same subframe. The self-contained integrated subframe supports communications in unlicensed or contention-based shared spectrum, and supports adaptive UL / downlink that can be flexibly configured on a per-cell basis to dynamically switch between UL and downlink to meet current traffic needs.

[0034] Commercial power amplifiers typically have nonlinear behavior if operated at high input power. This nonlinearity can cause in-band and out-of-band distortion of the signal, as well as a reduced error vector magnitude (EVM) at the receiver of the signal. In order to avoid nonlinearity, the power amplifier can operate at an average input power several dB lower than the saturation point. If the signal has a peak-to-average power ratio (PAPR) of x dB, an input backoff (IBO) of x dB can be used to avoid nonlinearity even at the peak of the input signal. In one example, providing an IBO at a value much larger than the PAPR results in underutilization of the power amplifier, resulting in the transmitter transmitting at less than full power. In another example, if the IBO is significantly less than the PAPR, the power amplifier is driven to saturation, and the signal at the receiver becomes distorted. In some aspects, the appropriate power level can be determined by determining the input power that keeps the PAPR of the signal below a specific level.

[0035] OFDM signals are known to suffer from significant PAPR, which grows rapidly with the size of the frequency block. 5G NR is being developed to support higher data rates than LTE. Therefore, the 5G NR OFDM block size can be larger than the LTE block size, further increasing the PAPR of the signal. Some PAPR reduction techniques may be data dependent and computationally expensive, making them unsuitable for real-time implementation in the context of 5G NR transmitters. As a result, clipping and filtering (CF) techniques are often used in the industry. CF causes in-band distortion and typically does not converge to the desired solution.

[0036] 5G NR provides abundant bandwidth in both uplink and downlink. This is true because of the addition of frequency range 2 (FR2) in 5G NR and the increase in available bandwidth to 100 MHz in the sub-6 GHz frequency range. This excess bandwidth is partially utilized by using longer OFDM symbols, which further increases the PAPR for OFDM. The excess bandwidth can also be used for PAPR reduction via a technique called tone reservation.

[0037] Tone reservation allows the transmitter to utilize some of the otherwise idle tones (or subcarriers) to reduce the PAPR of the OFDM signal. The amplitude and phase of the reserved tones can be optimized for a given OFDM symbol to minimize the PAPR of the associated signal. In some cases, there may be no overlap between the data tones and the reserved tones. In this way, tone reservation can be used without introducing any EVM or adjacent channel leakage ratio (ACLR). The receiver can simply ignore the portion of the signal associated with the reserved tones and only decode the portion of the signal associated with the data tones.

[0038] Tone preservation may be performed by determining a peak reduction tone (PRT) configured to reduce the peak of the resulting OFDM signal so that the PAPR of the resulting OFDM signal meets a threshold. The PRT may be generated using a signal-limited signal-to-noise ratio tone preservation (SCR-TR) algorithm. The SCR-TR algorithm may be used to optimize the values ​​of the PRT tones based at least in part on their locations.

[0039] A set of N transmission tones {1, ..., N} with a corresponding set of tone position indices may be allocated to the UE. If Φ is a subset of {1, ..., N} corresponding to the PRT positions, then the remaining transmission tone positions may be allocated to data tones in the tone position indices, which have the subset {1, ..., N}\Φ. A frequency domain kernel P may be constructed i , so that:

[0040]

[0041] And p = iDFT(P). X can be frequency domain data. Therefore, if i∈Φ and x = iDFT(X), then X i =0.

[0042] According to the SCR-TR algorithm, the location of the maximum peak of x is identified and its index is denoted by j∈[LN], where L is the oversampling factor. SCR-TR includes cyclic shifts p, p j = cyclic shift (p, j) so that the peaks are aligned. SCR-TR further includes subtracting the scaled and shifted p from x to obtain:

[0043]

[0044] where μ is the target peak, <x(j) is the phase of x(j), This process is iterated several times to reduce several peaks. If the number of retained tones is large enough and the positions are chosen correctly, the time domain kernel p has a single prominent and narrow peak. Additionally, the cyclic shift p in the time domain does not affect the position of the PRTs in the frequency domain, only disturbing their phase.

[0045] As discussed above, OFDM signals cause high PAPR, which leads to inefficient use of the power amplifier. If the power amplifier is pushed to the saturation point, the high PAPR of the CP-OFDM waveform leads to high EVM and ACLR at the receiver. On the other hand, if the power amplifier is not fully utilized, the transmitter cannot transmit at full power. Therefore, it is desirable to reduce the PAPR of the OFDM symbols before feeding the OFDM symbols to the power amplifier. Tone preservation is a known technique for reducing PAPR. As discussed above, this technique allows the transmitter to utilize some idle tones to eliminate peaks in the time domain. However, peak reduction tones are generally considered to be wasted resources that are used for the purpose of reducing PAPR and not for data transmission.

[0046] The present technology provides for a UE to transmit data tones interleaved with peak reduction tones, wherein a first subset of the data tones are interleaved with the peak reduction tones and a second subset of the data tones are overlapped with the peak reduction tones by modulating the overlapping data tones with a modulation scheme of a different order than the modulation scheme of the non-overlapping data tones. The present technology also provides various signaling aspects that enable the UE and a base station (e.g., a gNB) to coordinate the use of a PRT and the selection of a modulation scheme for the data tones and the PRT.

[0047] By overlapping certain sets of data tones with sets of peak reduction tones, spectral efficiency can be improved while keeping EVM values ​​within acceptable ranges for each tone range. By pre-fixing the positions of the PRTs, transmitter complexity is significantly improved since optimization may not be performed in real time. While the amplitude and phase of the retained tones can be adjusted for each symbol, the PRTs have a generally beneficial index assignment.

[0048] Various aspects are described herein in conjunction with wireless communication devices. Wireless communication devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, mobile devices, cellular devices, multimode devices, remote stations, remote terminals, access terminals, user terminals, user agents, user devices, or user equipment, etc. A subscriber station may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, or similar mechanisms that facilitate wireless communication with a processing device.

[0049] Various other aspects and features of the present disclosure are further described below. It should be apparent that the teachings herein can be embodied in a variety of forms, and any specific structure, function, or both disclosed herein are representative and non-restrictive. Based on the teachings herein, it should be appreciated by those of ordinary skill in the art that the aspects disclosed herein can be implemented independently of any other aspects and two or more of these aspects can be combined in various ways. For example, any number of aspects set forth herein can be used to implement a device or practice a method. In addition, other structures, functionality, or structures and functionality that are supplementary to or different from one or more aspects set forth herein can be used to implement such a device or practice such a method.

[0050] Figure 1 A wireless communication network 100 according to various aspects of the present disclosure is illustrated. The network 100 includes a BS 105, a UE 115, and a core network 130. In some instances, the network 100 operates on a shared spectrum band. The shared spectrum band may not be licensed or partially licensed to one or more network operators. Access to the spectrum may be restricted and may be controlled by a separate coordination entity. In some instances, the network 100 may be a 5G NR network. In other instances, the network 100 may be an LTE or LTE-A network. In yet other embodiments, the network 100 may be a millimeter wave (mmW) network, a 5G NR network, a 5G+ network, an ultra-wideband (UWB) network, or any other successor network of LTE. The network 100 may be operated by more than one network operator. Wireless resources may be divided and arbitrated between different network operators to enable coordinated communication between network operators through the network 100.

[0051] BS 105 can communicate wirelessly with UE 115 via one or more BS antennas. Each BS 105 can provide communication coverage for a corresponding geographic coverage area 110. In 3GPP, the term "cell" can refer to the specific geographic coverage area of ​​the BS and / or the BS subsystem serving the coverage area, depending on the context in which the term is used. In this regard, BS 105 can provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. Macro cells generally cover a relatively large geographic area (e.g., a radius of several thousand meters) and can allow unrestricted access by UEs with service subscriptions to network providers. Pico cells generally cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions to network providers. Femto cells generally cover a relatively small geographic area (e.g., a residence) and can provide restricted access by UEs associated with the femto cells (e.g., UEs in a closed subscriber group (CSG), UEs of users in the residence, etc.) in addition to unrestricted access. A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. Figure 1 In the example shown in FIG. 1 , BSs 105a, 105b, and 105c are examples of macro BSs for coverage areas 110a, 110b, and 110c, respectively. BS 105d is an example of a pico BS or a femto BS for coverage area 110d. As will be appreciated, BS 105 may support one or more (e.g., two, three, four, etc.) cells.

[0052] The communication link 125 shown in the network 100 may include an uplink (UL) transmission from the UE 115 to the BS 105, or a downlink (DL) transmission from the BS 105 to the UE 115. The UEs 115 may be dispersed throughout the network 100, and each UE 115 may be stationary or mobile. The UE 115 may also be referred to as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable term. The UE 115 may also be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a personal electronic device, a handheld device, a personal computer, a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, a machine type communication (MTC) device, an appliance, a car, etc. In one aspect, UE 115 may be a device including a universal integrated circuit card (UICC). In another aspect, UE may be a device that does not include a UICC. In some aspects, UE 115 that does not include a UICC may also be referred to as an IoT device or an Internet of Everything (IoE) device. UE 115a-115d is an example of a mobile smart phone type device that accesses network 100. In one aspect, UE 115c and 115d communicate with each other via a side link transmission between UE 115c and 115d in coverage area 110f. UE 115 may also be a machine specifically configured for connected communications (including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc.). MTC UE and eMTC UE include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. UE 115 may be considered as customer base equipment (CPE). UE 115 may be included inside a housing that houses components of UE 115, such as a processor component, a memory component, and the like. UE 115e-115h are examples of various machines configured for communication of access network 100. UE 115i-115k are examples of vehicles equipped with wireless communication devices configured for communication of access network 100 in coverage area 110e. UE 115 may be able to communicate with any type of BS (whether a macro BS, a small cell, etc.). Figure 1In the figure, the lightning beam (e.g., communication link) indicates a wireless transmission between UE 115 and a serving BS 105, a desired transmission between BSs 105, a backhaul transmission between BSs, or a sidelink transmission between UEs 115, where serving BS 105 is a BS designated to serve UE 115 on a downlink (DL) and / or uplink (UL).

[0053] The network 100 may also support mission-critical communications with ultra-reliable and redundant links for mission-critical devices, such as UE 115e, which may be a drone. The redundant communication links with UE 115e may include a link from macro BS 105c, and a link from small cell BS 105f. Other machine-type devices, such as UE 115f (e.g., a thermometer), UE 115g (e.g., a smart meter), and UE 115h (e.g., a wearable device), may communicate directly with a BS, such as small cell BS 105f and macro BS 105c, through the network 100, or in a multi-step configuration by communicating with another user device that relays its information to the network, such as UE 115f communicating temperature measurement information to smart meter UE 115g, which is then reported to the network through small cell BS 105f. The network 100 may also provide additional network efficiency through dynamic, low latency TDD / FDD communications, such as V2V, V2X, C-V2X communications between UE 115i, 115j, or 115k and other UEs 115, and / or vehicle-to-infrastructure (V2I) communications between UE 115i, 115j, or 115k and BS 105a.

[0054] Each BS 105 may communicate with the core network 130 and with each other. The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the BSs 105 (e.g., which may be examples of evolved Node Bs (eNBs), next generation Node Bs (gNBs), or access node controllers (ANCs)) may interface with the core network 130 via a backhaul link 132 (e.g., S1, S2, etc.) and may perform radio configuration and scheduling to communicate with the UE 115. In various examples, the BSs 105 may communicate with each other directly or indirectly (e.g., through the core network 130) on a backhaul link 134 (e.g., X1, X2, etc.), which may be a wired or wireless communication link.

[0055] Each BS 105 may also communicate with a number of UEs 115 through a number of other BSs 105, where the BSs 105 may be examples of smart radio heads. In alternative configurations, the various functions of each BS 105 may be distributed across the various BSs 105 (e.g., radio heads and access network controllers) or merged into a single BS 105.

[0056] In some implementations, the network 100 utilizes orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the UL. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as frequency tones, frequency bins, etc. Each subcarrier can be modulated with data. In general, modulation symbols are sent in the frequency domain for OFDM and in the time domain for SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. The system bandwidth can also be divided into subbands.

[0057] In one example, BS 105 may assign or schedule transmission resources (e.g., in the form of time-frequency resource blocks) for DL ​​and UL transmissions in network 100. DL refers to the transmission direction from BS 105 to UE 115, while UL refers to the transmission direction from UE 115 to BS 105. The communication may take the form of a radio frame. A radio frame may be divided into a plurality of subframes, e.g., about 10. Each subframe may be divided into time slots, e.g., about 2. Each time slot may be further divided into mini-slots, as described in more detail herein. In frequency division duplex (FDD) mode, simultaneous UL and DL transmissions may occur in different frequency bands. For example, each subframe includes a UL subframe in the UL frequency band and a DL subframe in the DL frequency band. In time division duplex (TDD) mode, UL and DL transmissions occur in different time periods using the same frequency band. For example, a subset of subframes in a radio frame (eg, DL subframes) may be used for DL ​​transmission, and another subset of subframes in the radio frame (eg, UL subframes) may be used for UL transmission.

[0058] DL subframes and UL subframes may be further divided into several regions. For example, each DL or UL subframe may have a predefined region for the transmission of reference signals, control information, and data. A reference signal is a predetermined signal that facilitates communication between BS 105 and UE 115. For example, a reference signal may have a specific pilot pattern or structure, wherein the pilot tones may span an operating bandwidth or frequency band, and each pilot tone is positioned at a predefined time and a predefined frequency. For example, BS 105 may transmit a reference signal (CRS) and / or a channel state information reference signal (CSI-RS) that varies from cell to cell to enable UE 115 to estimate a DL channel. Similarly, UE 115 may transmit a sounding reference signal (SRS) to enable BS 105 to estimate an UL channel. Control information may include resource assignments and protocol controls. Data may include protocol data and / or operational data. In some instances, BS 105 and UE 115 may communicate using self-contained subframes. A self-contained subframe may include a portion for DL ​​communication and a portion for UL communication. A self-contained subframe may be DL-centric or UL-centric. A DL-centric subframe may include a duration for DL ​​communication that is longer than a duration for UL communication. A UL-centric subframe may include a duration for UL communication that is longer than a duration for UL communication.

[0059] In some aspects, network 100 may be a 5G NR network deployed on a licensed spectrum. BS 105 may transmit synchronization signals (e.g., including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)) in network 100 to facilitate synchronization. BS 105 may broadcast system information associated with network 100 (e.g., including a master information block (MIB), remaining system information (RMSI), and other system information (OSI)) to facilitate initial network access. In some instances, BS 105 may broadcast PSS, SSS, and / or MIB in the form of a synchronization signal block (SSB) on a physical broadcast channel (PBCH), and may broadcast RMSI and / or OSI on a physical downlink shared channel (PDSCH).

[0060] In one example, a UE 115 attempting to access the network 100 may perform an initial cell search by detecting a primary synchronization signal (PSS) from the BS 105. The PSS may enable synchronization of periodic timing and may indicate a sector identity value (e.g., 0, 1, 2, etc.). The UE 115 may then receive a secondary synchronization signal (SSS). The SSS may enable radio frame synchronization and may provide a cell identity value that may be combined with a PSS identity value to identify a physical cell identity. The SSS may also enable detection of a duplex mode and a cyclic prefix length. Both the PSS and the SSS may be located at a center portion of a carrier, respectively. After receiving the PSS and the SSS, the UE 115 may receive a master information block (MIB), which may be transmitted in a physical broadcast channel (PBCH). The MIB may include system bandwidth information, a system frame number (SFN), and a physical hybrid ARQ indicator channel (PHICH) configuration. After decoding the MIB, the UE 115 may receive one or more system information blocks (SIBs). For example, SIB1 may contain cell access parameters and scheduling information for other SIBs. Decoding SIB1 may enable UE 115 to receive SIB2. SIB2 may contain radio resource configuration (RRC) configuration information related to random access channel (RACH) procedures, paging, physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), power control, SRS, and cell barring. After obtaining the MIB and / or SIB, UE 115 may perform a random access procedure to establish a connection with BS 105.

[0061] After establishing the connection, UE 115 and BS 105 may enter a normal operation phase, during which operation data may be exchanged. For example, BS 105 may schedule UE 115 for UL and / or DL ​​communications. BS 105 may transmit UL and / or DL ​​scheduling grants to UE 115 via PDCCH. Scheduling grants may be transmitted in the form of DL control information (DCI). BS 105 may transmit DL communication signals (e.g., carrying data) to UE 115 via PDSCH according to the DL scheduling grant. UE 115 may transmit UL communication signals to BS 105 via PUSCH and / or PUCCH according to the UL scheduling grant.

[0062] In some aspects, the network 100 may support sidelink communications on a shared radio frequency band (e.g., in a shared spectrum or an unlicensed spectrum) between UEs 115. In some aspects, the UEs 115 may communicate with each other on a 2.4 GHz unlicensed band that may be shared by multiple network operating entities using different radio access technologies (RATs) such as NR-U, WiFi, and / or Licensed Assisted Access (LAA).

[0063] In some instances, UE 115 and BS 105 may be operated by multiple network operators or network operating entities and may operate in a shared radio frequency spectrum, which may include licensed or unlicensed frequency bands. The shared spectrum may be divided in time for sharing between multiple network operating entities, thereby facilitating coordinated communications. For example, in network 100, BS 105a and UE 115a may be associated with one network operating entity, while BS 105b and UE 115b may be associated with another network operating entity. By dividing the shared spectrum in time according to the network operating entity, communications between BS 105a and UE 115a and communications between BS 105b and UE 115b may each occur during a corresponding time period and may utilize the entire designated shared spectrum.

[0064] In an example, the network 100 may support multiple networks with different RAT technologies. For example, the network 100 may be initially deployed as an LTE network, and then an advanced RAT technology such as 5G NR may be added to provide improved network functionality, such as lower latency, greater bandwidth, and / or higher throughput. The mechanism of deploying a 5G NR network in an LTE network is described in more detail herein.

[0065] In various examples, the UE 115 includes a transceiver configured to obtain a frequency list in system information from a first serving cell (e.g., 105c) associated with a first wireless communication network. The UE 115 also includes a processor configured to determine from the frequency list a first frequency band supported by the first serving cell (e.g., 105c) and a second frequency band supported by one or more second serving cells (e.g., 105b) for dual connectivity with the first wireless communication network and the second wireless communication network. The UE 115 may be adapted to determine whether the first serving cell (e.g., 105c) supports dual connectivity using a frequency band-frequency combination supported by the UE 115 based on the first frequency band and the second frequency band. The UE 115 also includes a user interface configured to provide a first indication of a first service associated with one or more second serving cells (e.g., 105b) for display on a display device of the UE 115 when the first serving cell (e.g., 105c) supports dual connectivity using a frequency band-frequency combination supported by the UE 115.

[0066] Figure 2 2 is a block diagram conceptually illustrating an example of a base station 205 and a UE 215 in communication in a wireless communication network 200 according to various aspects of the present disclosure. The UE 215 may be a base station 205 as described above. Figure 1 The UE 115 in the network 100 discussed in the above, and the BS 205 can be as described above in Figure 1 BS 105 in network 100 discussed in . BS 205 may be equipped with T antennas 234a through 234t, and UE 215 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0067] At BS 205, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS 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), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 235 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may 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 may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0068] At UE 215, antennas 252a to 252r may receive downlink signals from BS 205 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 215 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 215 may be included in a housing.

[0069] On the uplink, at the UE 215, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the BS 205. At the BS 205, uplink signals from the UE 215 and other UEs may be received by the antenna 234, processed by the demodulator 254, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 215. The receive processor 238 may provide decoded data to a data sink 239 and decoded control information to a controller / processor 240. The base station 205 may include a communication unit 244 and communicate with the network controller 230 via the communication unit 244. The network controller 230 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0070] The controller / processor 240 of the BS 205, the controller / processor 280 of the UE 215, and / or Figure 2Any other component(s) of the BS 205 may perform one or more techniques associated with tone preservation for PAPR reduction, as described in more detail elsewhere herein. For example, the controller / processor 240 of the BS 205, the controller / processor 280 of the UE 215, and / or Figure 2 Any other component(s) may perform or direct e.g. Figure 8 The process of 800 Fig. 9 The operations of the process 900, and / or other processes as described herein. Memories 242 and 282 may store data and program codes for use by BS 205 and UE 215, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0071] The stored program code, when executed by the processor 280 and / or other processors and modules at the UE 215, may cause the UE 215 to perform operations related to Figure 8 The stored program code, when executed by the processor 240 and / or other processors and modules at the BS 205, may cause the BS 205 to perform operations related to the process 800 and / or other processes described herein. Fig.10 The operations described by process 1000 and / or other processes described herein.

[0072] Although in Figure 2 The blocks in the figure are illustrated as different components, but the functions described above with respect to these blocks may be implemented with a single hardware, software, or combined component or various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by the processor 280 or under the control of the processor 280.

[0073] In some aspects, the UE 215 may transmit data tones interleaved with peak reduction tones, wherein a first subset of the data tones are interleaved with the peak reduction tones and a second subset of the data tones are overlapped with the peak reduction tones by modulating the overlapping data tones with a modulation scheme of a different order than the modulation scheme of the non-overlapping data tones. Additionally, specific PRT signaling may be exchanged between the UE 215 and the BS 205 to enable the UE 215 and the BS 205 to coordinate the use of the PRT and the selection of modulation schemes for both the data tones and the PRT. By overlapping certain data tones with peak reduction tones, the spectral efficiency of PRT bandwidth utilization may be improved while maintaining EVM values ​​within an acceptable range for each tone range.

[0074] Figure 3 1 is a block diagram illustrating an exemplary UE 300 according to various aspects of the present disclosure. The UE 300 may be as described above in Figure 1115 in the network 100 discussed in Figure 2 2. As shown, UE 300 may include a processor 302, a memory 304, a resource allocation module 308, a transceiver 310 including a modem subsystem 312 and a radio frequency (RF) unit 314, and one or more antennas 316.

The instructions 306 may also be referred to as code. The terms "instructions" and "code" should be interpreted broadly to include any type of computer-readable statements. For example, the terms "instructions" and "code" may refer to one or more programs, routines, subroutines, functions, procedures, etc. "Instructions" and "code" may include a single computer-readable statement or a plurality of computer-readable statements.

The modem subsystem 312 may be configured to modulate and / or encode data from the memory 304 according to a modulation and coding scheme (MCS) (e.g., a low density parity check (LDPC) coding scheme, a turbo coding scheme, a convolutional coding scheme, a digital beamforming scheme, etc.). The RF unit 314 may be configured to process (e.g., perform analog-to-digital conversion or digital-to-analog conversion, etc.) the modulated / coded data from the modem subsystem 312 (for outbound transmissions) or the modulated / coded data of a transmission originating from another source, such as the UE 115 or the BS 105. The RF unit 314 may be further configured to perform analog beamforming in conjunction with digital beamforming. Although shown as being integrated together in the transceiver 310, the modem subsystem 312 and the RF unit 314 may be separate devices that are coupled together at the UE 300 to enable the UE 300 to communicate with other devices.

[0078] RF unit 314 may provide modulated and / or processed data, such as a data packet (or more generally, a data message that may include one or more data packets and other information), to antenna 316 for transmission to one or more other devices. Antenna 316 may further receive data messages transmitted from other devices. Antenna 316 may provide received data messages for processing and / or demodulation at transceiver 310. Antenna 316 may include multiple antennas of similar or different designs in order to maintain multiple transmission links. RF unit 314 may configure antenna 316.

[0079] The resource allocation module 308 may be adapted to receive a resource allocation indicating a transmission tone set having a first data tone set, a second data tone set, and a PRT set. The resource allocation module 308 may cooperate with the transceiver 310 to receive the resource allocation by receiving one or more PDCCHs of a plurality of PDCCHs. The resource allocation module 308 may cooperate with the modem 312 to decode the one or more PDCCHs to recover downlink control information (DCI) in the one or more PDCCHs of the plurality of PDCCHs. In other aspects, the resource allocation module 308 may cooperate with the transceiver 310 to receive the resource allocation in a media access control (MAC) control element (MAC-CE). In other aspects, the resource allocation module 308 may cooperate with the transceiver 310 to receive the resource allocation 502 in a radio resource control (RRC) message.

[0080] The modem 312 may be adapted to decode the DCI to recover the PRTT. The resource allocation module 308 may cooperate with the modem 312 to obtain an indication of one or more entries in the PRTT including the PRT sequence from the DCI. The resource allocation module 308 may cooperate with the modem 312 to obtain the PRT sequence from one or more entries in the PRTT. The resource allocation module 308 may obtain an indication of one or more entries in the PRTT including the PRT sequence from the DCI. In this way, the resource allocation module 308 may obtain the PRT sequence from one or more entries in the PRTT. In other aspects, the resource allocation module 308 may obtain an indication of one or more entries in the PRTT including one or more parameters of a deterministic function from the DCI. In this aspect, the processor 402 may cooperate with the resource allocation module 308 to generate the PRT sequence using a deterministic function with one or more parameters. In some aspects, the deterministic function includes at least one of a Golomb ruler, a Costas array, a Gold sequence, or a linear function. In some aspects, resource allocation module 308 may cooperate with transceiver 310 to receive a PRT sequence from BS 105 indicating which tones in a set of transmission tones are designated as a PRT set.

[0081] In some aspects, the resource allocation module 308 may cooperate with the modem 312 to determine, based on the PRT sequence, that a first set of data tones corresponds to a first order modulation scheme and a second set of data tones corresponds to a second order modulation scheme having a greater order than the first order modulation scheme. The resource allocation module 308 may infer a modulation scheme for the first set of data tones by determining the first order modulation scheme for the first set of data tones based on at least a portion of the second order modulation scheme. In some aspects, the resource allocation module 308 may cooperate with the processor 302 to determine, based at least on a first MCS corresponding to the first set of data tones, that the first set of data tones corresponds to a first transmission power and the second set of data tones corresponds to a second transmission power that is less than the first transmission power. In some aspects, the resource allocation module 308 may cooperate with the processor 302 to determine, based on one or more entries in the PRTT, that the first set of data tones corresponds to a first transmission power and the second set of data tones corresponds to a second transmission power. In some aspects, when the second order modulation scheme is equal to the first order modulation scheme, resource allocation module 308 may cooperate with transceiver 310 to receive a request to assign different transmission powers to the first set of data tones and the second set of data tones from BS 105. In this aspect, resource allocation module 308 may cooperate with processor 302 to assign the first transmission power to the first set of data tones 526 and the second transmission power to the second set of data tones based on the request.

[0082] The RF unit 314 may cooperate with the resource allocation module 308 and be adapted to transmit a data transmission 518 including an outgoing waveform based at least in part on the resource allocation.

[0086] The resource configuration module 408 may cooperate with the processor 402 and be adapted to perform noise estimation for a first set of data frequency tones corresponding to data frequency tones having a first order MCS modulation based at least in part on a configuration that assigns the UE to utilize a set of PRTs at fixed positions within a specific bandwidth to reduce the PAPR peak of one or more OFDM symbols while the UE complies with an assigned power constraint for the first set of data frequency tones.

[0087] As shown, the transceiver 410 may include a modem subsystem 412 and an RF unit 414. The transceiver 410 may be configured to communicate bidirectionally with other devices, such as UE 115 and / or 300 and / or another core network element. The modem subsystem 412 may be configured to modulate and / or encode data according to an MCS (e.g., an LDPC coding scheme, a turbo coding scheme, a convolutional coding scheme, a polarization coding scheme, a digital beamforming scheme, etc.). The RF unit 414 may be configured to process (e.g., perform analog-to-digital conversion or digital-to-analog conversion, etc.) modulated / encoded data from the modem subsystem 412 (on outbound transmission) or modulated / encoded data originating from another source, such as UE 115, UE 215, and / or UE 300. The RF unit 414 may be further configured to perform analog beamforming in conjunction with digital beamforming. Although shown as being integrated together in transceiver 410, modem subsystem 412 and / or RF unit 414 may be separate devices that are coupled together at BS 105 to enable BS 105 to communicate with other devices.

[0088] The RF unit 414 may provide modulated and / or processed data (e.g., data packets (or more generally, data messages that may include one or more data packets and other information)) to the antenna 416 for transmission to one or more other devices. This may include, for example, information transmission to complete attachment to a network and communication with a resident UE 115, 215, or 300 in accordance with some aspects of the present disclosure. The antenna 416 may further receive data messages transmitted from other devices and provide the received data messages for processing and / or demodulation at the transceiver 410. The transceiver 410 may provide the demodulated and decoded data (e.g., RRC connection complete, RRC connection reconfiguration complete) to the processor 402 for processing. The antenna 416 may include multiple antennas of similar or different designs in order to maintain multiple transmission links.

[0089] The transceiver 410 can cooperate with the resource configuration module 408 and the RF unit 414 and be adapted to communicate a resource allocation with the UE in a first subband of the plurality of subbands, the resource allocation indicating a set of transmission tones including a first set of data tones, a second set of data frequency channels, and a set of peak reduction tones. In some aspects, the resource allocation indicates that the first set of data tones overlaps with at least a portion of the set of PRTs at corresponding positions in the set of PRT positions, while the second set of data tones is arranged at the set of data tone positions within a specific bandwidth. The transceiver 410 can also be adapted to receive a data transmission including an incoming waveform from the UE in a second subband of the plurality of subbands based at least in part on the resource allocation.

[0091] Figure 5

[0026] Diagrams illustrating examples of tone preservation with peak reduction tones and overlapping data tones in accordance with various aspects of the present disclosure are illustrated.As shown, a BS 105 and a UE 115 may communicate with each other.

[0092] BS 105 may transmit, and UE 115 may receive, resource allocation 502. Resource allocation 504 may indicate a set of transmission tones 504. Set of transmission tones 504 may include a first set of data tones 526 (depicted by longer thick vertical bars), a second set of data tones 506 (depicted by longer thin vertical bars), and a set of PRTs 508 (depicted by shorter vertical bars). Resource allocation 502 may indicate a set of data tone positions 510 within a particular bandwidth (depicted as "BW"). Resource allocation 502 may indicate a set of PRT positions 512 within a particular bandwidth. In some aspects, set of PRT positions 512 may be arranged relative to set of data tone positions 510 according to a PRT sequence 514. As shown, PRT sequence 514 may include PRTs 508 interleaved with second set of data tones 506.

[0093] In some aspects, resource allocation 502 indicates that first set of data tones 526 overlap at least a portion of set of PRTs 508 at respective positions in set of PRT positions 512, while second set of data tones 506 are arranged at set of data tone positions 510 within a particular bandwidth. In various instances, first set of data tones 526 are arranged to not overlap with second set of data tones 506. In some instances, first set of data tones 526 partially overlap with set of PRTs 508. In one instance, first set of data tones 526 overlaps with set of PRTs 508 in its entirety. In various instances, each second data tone in second set of data tones 506 is arranged to not overlap with set of PRTs 508. In one instance, second set of data tones 506 partially overlaps with set of PRTs 508 by a first overlap amount. In various instances, first set of data tones 526 at least partially overlaps with set of PRTs 508 by at least a second overlap amount. In various examples, the second amount of overlap is greater than the first amount of overlap.

[0094] In some aspects, the resource allocation 502 may be carried in downlink control information (DCI), a radio resource control (RRC) message, a media access control (MAC) control element (CE), etc. In various aspects, the UE 115 receives the resource allocation 502 from the BS 105 in a first subband of a plurality of subbands. In some aspects, the first subband includes a plurality of subcarriers (or a plurality of tones). In various instances, the first subband includes a plurality of PDCCHs multiplexed in at least one of time or frequency. The UE 115 may receive the resource allocation 502 by receiving one or more of the plurality of PDCCHs. The UE 115 may decode the one or more PDCCHs to recover the downlink control information (DCI) in one or more of the plurality of PDCCHs. In some instances, the DCI includes a frequency domain resource assignment for the UE 115 including the resource allocation 502. In other aspects, the UE 115 may receive the resource allocation 502 from the BS 105 in a radio resource control (RRC) message. In other aspects, the UE 115 may receive the resource allocation 502 from the BS 105 in a medium access control (MAC) control element (MAC-CE).

[0095] In some aspects, the resource allocation 502 may indicate a PRT sequence 514 by reference to a PRT table (PRTT) associated with the resource allocation 502. In some aspects, the PRTT may indicate multiple PRT sequences. In some aspects, the UE 115 may decode the DCI to recover the PRTT. The UE 115 may obtain an indication of one or more entries in the PRTT including the PRT sequence 514 from the DCI. The UE 115 may obtain the PRT sequence 514 from one or more entries in the PRTT. In some aspects, the PRTT provides a predetermined PRT position for a PRT position set 512 having a PRT sequence 514. In some aspects, the PRT position set 512 is arranged relative to the data frequency modulation position set 510 according to the PRT sequence 514.

[0096] In some aspects, the PRTT may indicate multiple entries. An entry in the multiple entries may include a PRT sequence 514, one or more parameters of a deterministic function, etc. In some aspects, the UE 115 obtains an indication of one or more entries in the PRTT including one or more parameters of a deterministic function from the DCI. In some aspects, the multiple entries may indicate multiple deterministic functions. Each entry in the multiple entries may correspond to a corresponding deterministic function in multiple deterministic functions. In some aspects, the UE 115 generates the PRT sequence 514 using a deterministic function with one or more parameters. In some aspects, the deterministic function includes at least one of a Golomb scale, a Costas array, a Gold sequence, or a linear function. The deterministic function may provide a predetermined PRT position for a PRT position set 512 having a PRT sequence 514. In some aspects, the UE 115 may determine that the first data frequency tone set 526 corresponds to a first transmission power and the second data frequency tone set 506 corresponds to a second transmission power based on one or more entries in the PRTT. In receiving resource allocation 502 , UE 115 may receive a PRT sequence 514 from BS 105 indicating which frequencies in transmission frequency tone set 504 are designated as PRT set 508 .

[0097] In some aspects, the first data tone set 526 includes first data tones corresponding to a first order modulation scheme, and the second data tone set 506 includes second data tones corresponding to a second order modulation scheme. In various instances, the second order modulation scheme is different from the first order modulation scheme. For example, the second order modulation scheme has a higher order than the first order modulation scheme. In one example, the first order modulation scheme includes quadrature phase shift keying (QPSK) modulation, and the second order modulation scheme includes 256-bit quadrature amplitude modulation (256-QAM) modulation, although other modulation schemes may be implemented without departing from the scope of the present disclosure. In some instances, the second order modulation scheme is equivalent to the first order modulation scheme. In some aspects, the UE 115 may determine that the first data tone set 526 corresponds to the first order modulation scheme based on the PRT sequence 514. In some aspects, the PRT sequence 514 indicates that the second data tone set 506 corresponds to a second order modulation scheme having an order greater than the order of the first order modulation scheme.

[0098] Upon receiving the resource allocation 520, the UE 115 may receive MCS information regarding the transmission frequency tone set 504 from the BS 105. In some aspects, the MCS information may include second MCS information for the second data frequency tone set 506. As such, the UE 115 may infer a modulation scheme for the first data frequency tone set 526 by determining a first MCS for the first data frequency tone set 526 based on at least a portion of the second MCS. In other aspects, the MCS information may include a first MCS for the first data frequency tone set 526 and a second MCS for the second data frequency tone set 506, wherein the second MCS has an order greater than an order of the first MCS. In some aspects, the UE 115 may determine, based at least on the first MCS corresponding to the first data frequency tone set 526, that the first data frequency tone set 526 corresponds to a first transmission power and the second data frequency tone set 506 corresponds to a second transmission power less than the first transmission power.

[0099] In some aspects, the UE 115 may assign a first transmission power to the first set of data tones 526 and a second transmission power to the second set of data tones 506. In various examples, the first transmission power is greater than the second transmission power in data transmission to help prevent significant distortion of the first set of data tones 526 by noise introduced by the PRT set 508. In some aspects, when the second order modulation scheme is equal to the first order modulation scheme, the UE 115 may receive a request from the BS 105 to assign different transmission powers to the first set of data tones 526 and the second set of data tones 506. For example, both the first set of data tones 526 and the second set of data tones 506 may be modulated with a common modulation scheme, such as 256-QAM modulation. In this aspect, the UE 115 may assign the first transmission power to the first set of data tones 526 and the second transmission power to the second set of data tones 506 based on the request.

[0100] The UE 115 may generate a waveform, such as waveform 516, based at least in part on the resource allocation 502. In some aspects, the UE 115 may generate the waveform 516 by determining an inverse discrete Fourier transform of the set of transmission tones 504. In some aspects, the waveform 516 may include a CP-OFDM waveform. In some aspects, the waveform 516 may include a DFT-s-OFDM waveform. In some aspects, the set of PRTs 508 may be selected so that the PAPR associated with the waveform 516 satisfies the PAPR threshold by not exceeding the PAPR threshold. In some aspects, the UE 115 may generate the waveform 516 with the set of transmission tones 504 based on a PRT sequence 514, wherein the PRT sequence 512 indicates an arrangement of the set of PRT positions 512 relative to the set of data tone positions 510 within a particular bandwidth.

[0101] In some aspects, waveform 516 includes a first waveform corresponding to first data tone set 526, a second waveform corresponding to second data tone set 506, and a third waveform corresponding to PRT set 508. In one example, the sum of the first waveform and the second waveform can produce a first PAPR value. In another example, the sum of the first waveform, the second waveform, and the third waveform can produce a second PAPR value that is less than the second PAPR value. In other aspects, waveform 516 includes a first waveform corresponding to first data tone set 526 and a second waveform corresponding to PRT set 508. In one example, waveform 516 can exclude the third waveform corresponding to second data tone set 506 based on the second data tone set 506 having a corresponding relationship with a different wireless communication device (e.g., second UE 115) scheduled to transmit within a specific bandwidth assigned to UE 115.

[0102] The UE 115 may transmit, and the BS 105 may receive, a data transmission 518 including an incoming waveform, such as the waveform 516, based at least in part on the resource allocation 502. In some aspects, the UE 115 may communicate the data transmission 518 with the BS 105 in a second subband of the plurality of subbands. In some aspects, the second subband includes a plurality of PUSCHs multiplexed in at least one of time or frequency. In this aspect, the UE 115 may transmit the data transmission 518 to the BS 105 in one or more of the plurality of PUSCHs. In some aspects, the UE 115 may transmit the data transmission 518 with a first transmission power corresponding to the first data tone set 526 and a second transmission power corresponding to the second data tone set 506.

[0129] Figure 8A flow chart illustrating an exemplary process 800 for allocating peak reduction tones and overlapping data tones according to various aspects of the present disclosure. Various aspects of process 800 may be performed by a computing device (e.g., a processor, processing circuitry, and / or other appropriate components) of a wireless communication device or other appropriate means for performing the steps. For example, a wireless communication device (such as UE 115, UE 215, and / or 300) may utilize one or more components (such as a processor 302, a memory 304, a resource allocation module 308, a transceiver 310, a modem 312, and one or more antennas 316) to perform the steps of method 800. As illustrated, process 800 includes several enumerated steps, but various aspects of method 800 may include additional steps before, after, and between these enumerated steps. In some aspects, one or more of the enumerated steps may be omitted or performed in a different order.

[0130] Process 800 begins at block 802, where a UE receives a resource allocation (e.g., 502) from a base station (e.g., BS 105) in a first subband of a plurality of subbands, the resource allocation indicating a set of transmission tones including a first set of data tones (e.g., 526), ​​a second set of data tones (e.g., 516), and a set of peak reduction tones (e.g., 508). For example, the resource allocation may indicate that the first set of data tones overlaps with at least a portion of a set of PRTs at respective positions in a set of PRT positions, and the second set of data tones is arranged at a set of data tone positions that do not overlap with the set of PRP positions within a particular bandwidth. For example, the UE may receive the resource allocation using one or more components such as processor 302, transceiver 310, modem 312, RF unit 314, and one or more antennas 316.

[0131] Next, at step 804, the UE communicates a data transmission (e.g., 518) with the base station in a second subband of the plurality of subbands using an outgoing waveform (e.g., 516) based at least in part on the resource allocation. For example, the UE may utilize one or more components such as the processor 302, the transceiver 310, the modem 312, the RF unit 314, and the one or more antennas 316 to communicate the data transmission.

[0132] Fig. 9A flowchart of an exemplary process 900 for assigning different transmission powers to different data frequency tone subsets based on requests according to various aspects of the present disclosure is illustrated. Various aspects of process 900 may be performed by a computing device (e.g., a processor, a processing circuit, and / or other appropriate components) of a wireless communication device or other appropriate means for performing the steps. For example, a wireless communication device (such as UE 115, UE 215, and / or 300) may utilize one or more components (such as a processor 302, a memory 304, a resource allocation module 308, a transceiver 310, a modem 312, and one or more antennas 316) to perform the steps of method 900. As illustrated, process 900 includes several enumerated steps, but various aspects of method 900 may include additional steps before, after, and between these enumerated steps. In some aspects, one or more of the enumerated steps may be omitted or performed in a different order.

[0133] Process 900 begins at block 902, where the UE receives a request from a base station to assign different transmission powers to a first set of data tones (e.g., 526) and a second set of data tones (e.g., 506) when a second order modulation scheme corresponding to the second set of data tones is equivalent to a first order modulation scheme corresponding to the first set of data tones. In some aspects, in a data transmission, the first transmission power is greater than the second transmission power to help prevent significant distortion of the first set of data tones by noise introduced by a set of PRTs (e.g., 508). For example, the UE may receive the request using one or more components such as processor 302, transceiver 310, modem 312, RF unit 314, and one or more antennas 316.

[0134] Next, at step 904, the UE assigns a first transmission power to the first set of data tones and a second transmission power to the second set of data tones in the data transmission. For example, the UE may utilize one or more components (such as processor 302, resource allocation module 308, and transceiver 310) to assign the first transmission power and the second transmission power.

[0135] Fig.10A flow chart illustrating an exemplary process 1000 for assigning different transmission powers to different data tone subsets based on received resource allocations in accordance with various aspects of the present disclosure. Various aspects of process 1000 may be performed by a computing device (e.g., a processor, processing circuitry, and / or other appropriate components) of a wireless communication device or other appropriate means for performing the steps. For example, a wireless communication device (such as UE 115, UE 215, and / or 300) may utilize one or more components (such as a processor 302, a memory 304, a resource allocation module 308, a transceiver 310, a modem 312, and one or more antennas 316) to perform the steps of method 1000. As illustrated, process 1000 includes several enumerated steps, but various aspects of method 1000 may include additional steps before, after, and between these enumerated steps. In some aspects, one or more of the enumerated steps may be omitted or performed in a different order.

[0136] Process 1000 begins at block 1002, where the UE determines, based on resource allocation (e.g., 502), that a first set of data tones (e.g., 526) corresponds to a first transmission power and a second set of data tones (e.g., 516) corresponds to a second transmission power. In some aspects, in data transmission, the first transmission power is greater than the second transmission power to help prevent significant distortion of the first set of data tones by noise introduced by the set of PRTs (e.g., 508). For example, the UE may determine the first transmission power and the second transmission power using one or more components, such as processor 302, resource allocation module 308, and transceiver 310.

[0137] Next, at step 1004, the UE assigns a first transmission power to the first set of data tones and a second transmission power to the second set of data tones in the data transmission. For example, the UE may utilize one or more components (such as processor 302, resource allocation module 308, and transceiver 310) to assign the first transmission power and the second transmission power.

[0138] The UE then transmits a data transmission at a first transmission power corresponding to the first set of data tones and a second transmission power corresponding to the second set of data tones at step 1006. For example, the UE may utilize one or more components such as the processor 302, the transceiver 310, the modem 312, the RF unit 314, and the one or more antennas 316 to transmit the data transmission.

[0139] Fig.11A flowchart of an exemplary process 1100 for assigning different transmission powers to different data frequency tone subsets based on a modulation scheme according to various aspects of the present disclosure is illustrated. Various aspects of the process 1100 may be performed by a computing device (e.g., a processor, a processing circuit, and / or other appropriate components) of a wireless communication device or other appropriate means for performing the steps. For example, a wireless communication device (such as UE 115, UE 215, and / or 300) may utilize one or more components (such as a processor 302, a memory 304, a resource allocation module 308, a transceiver 310, a modem 312, and one or more antennas 316) to perform the steps of the method 1100. As illustrated, the process 1100 includes several enumerated steps, but various aspects of the method 1100 may include additional steps before, after, and between these enumerated steps. In some aspects, one or more of the enumerated steps may be omitted or performed in a different order.

[0140] Process 1100 begins at block 1102, where a UE receives modulation and coding scheme (MCS) information about a set of transmission tones from a base station (e.g., BS 105). In some aspects, the MCS information includes a first MCS for a first set of data tones (e.g., 526) and a second MCS for a second set of data tones (e.g., 506). In some aspects, the second MCS has a greater order than the first MCS. For example, the UE may receive the MCS information using one or more components such as processor 302, transceiver 310, modem 312, RF unit 314, and one or more antennas 316.

[0141] Next, at block 1104, the UE determines, based at least on the first MCS, that the first set of data tones corresponds to a first transmission power and the second set of data tones corresponds to a second transmission power that is less than the first transmission power. In some aspects, the first transmission power is greater than the second transmission power in data transmission to help prevent significant distortion of the first set of data tones by noise introduced by the set of PRTs (e.g., 508). For example, the UE may determine the first transmission power and the second transmission power using one or more components such as the processor 302, the resource allocation module 308, and the transceiver 310.

For example, a wireless communication device (such as BS 105, 205, and / or 400) may utilize one or more components (such as a processor 402, a memory 404, a resource configuration module 408, a transceiver 410, a modem 412, and one or more antennas 416) to perform the steps of method 1200. As illustrated, process 1200 includes several enumerated steps, but various aspects of method 1200 may include additional steps before, after, and between these enumerated steps. In some aspects, one or more of the enumerated steps may be omitted or performed in a different order.

[0143] Process 1200 begins at block 1202, where a BS communicates a resource allocation 502 with a user equipment (e.g., 115) in a first subband of a plurality of subbands, the resource allocation indicating a set of transmission tones (e.g., 504) including a first set of data tones (e.g., 526), ​​a second set of data tones (e.g., 506), and a set of peak reduction tones (e.g., 508). In some aspects, the resource allocation 502 indicates that the first set of data tones overlaps at least a portion of a set of PRTs at respective locations in a set of PRT locations, and the second set of data tones is arranged at a set of data tone locations within a particular bandwidth. For example, the BS may communicate the resource allocation using one or more components such as a processor 402, a transceiver 410, a modem 412, an RF unit 414, and one or more antennas 416.

[0144] Next, at step 1204, the BS receives a data transmission (e.g., 518) including an incoming waveform (e.g., 516) from the UE in a second subband of the plurality of subbands based at least in part on the resource allocation. For example, the BS may utilize one or more components such as the processor 402, the transceiver 410, the modem 412, the RF unit 414, and one or more antennas 416 to receive the data transmission.
