Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for tone preservation for peak-to-average power ratio reduction. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

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

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at municipal, national, regional, and even global levels. NR (also known as 5G) is a collection of enhancements to the LTE mobile standard released by 3GPP. NR aims to support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to better integrate with other open standards, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the invention

[0034] Typical methods for peak reduction tone (PRT) selection to reduce the peak-to-average power ratio (PAPR) in a power amplifier of a user equipment (UE) using orthogonal frequency division multiplexing (OFDM) signals may introduce unnecessary processing, which may cause performance degradation. In addition, the selection of PRT may not be known to the base station, and therefore will need to be signaled to the base station to facilitate decoding by the base station, thereby increasing signaling overhead. Aspects of the techniques and devices described herein may contribute to PRT reservation for reducing the PAPR of a power amplifier in a user equipment (UE). In some aspects, the tone reservation techniques described herein may facilitate PRT position determination based on established patterns, sequences, tables, etc. In some aspects, a PRT sequence may include a pseudo-random pattern generated using a pseudo-random number generator. In some aspects, a PRT sequence may include at least one plurality of continuous PRTs and at least one plurality of continuous data tones. The base station may indicate a PRT sequence, a pseudo-random number generator, a seed associated with a pseudo-random number generator, etc. to the UE. In this way, the PRT position may be determined without optimizing the random PRT index selection in real time, thereby reducing the complexity of transmitter operation. This can facilitate saving power and time during transmission, thereby improving performance, reducing computational burden, etc.

[0035] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently of any additional aspect of the present disclosure or implemented in combination with any additional aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using other structures, functionality or structures and functionality that are supplemented or added to the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0036] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0037] It should be noted that although terms generally associated with 5G or NR radio access technology (RAT) are used herein to describe various aspects, various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0038] Figure 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. Among other examples, the wireless network 100 may be or may include a unit of a 5G (NR) network and / or an LTE network. The wireless network 100 may include several 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 can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0039] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0040] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to 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.

[0041] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay BS 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0042] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0043] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. These BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0044] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), 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 biological sensor / device, a wearable device (smart watch, 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-mounted component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0045] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may, for example, provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or to a network via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as user premises equipment (CPE). UE 120 may be included in a housing that houses components of UE 120 (such as a processor component and / or a memory component). In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0046] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0047] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In such cases, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0048] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), which can span 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), which can span 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "below 6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified by the International Telecommunication Union (ITU) as a "millimeter wave" band. Therefore, unless otherwise specifically stated, it should be understood that the terms "sub-6 GHz," etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave," etc., if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0049] As mentioned above, Figure 1 This is provided as an example only. Other examples may differ from the combination of Figure 1 The content described.

[0050] Figure 2is 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 through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0051] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the (multiple) MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)).

[0065] Although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0066] As mentioned above, Figure 2 This is provided as an example only. Other examples may differ from the combination of Figure 2 The content described.

[0067] Commercial power amplifiers typically have nonlinear characteristics if operated at high input power. Such nonlinearities can cause in-band and out-of-band distortion of the signal, as well as a degraded error vector magnitude (EVM) at the receiver of the signal. To avoid nonlinearities, the power amplifier can be operated at an average input power several dB below the saturation point. The appropriate power level can be determined by determining the input power that keeps the peak-to-average power ratio (PAPR) of the signal below a certain level.

[0068] Orthogonal frequency division multiplexing (OFDM) signals are known to suffer from significant PAPR, which grows rapidly due to the size of the frequency blocks. 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 intensive, making them unsuitable for real-time implementation in the context of 5G NR transmitters. As a result, limiting and filtering (CF) is often used in industry. CF causes in-band distortion and typically does not converge to the desired solution.

[0069] 5G NR provides ample bandwidth in both uplink and downlink. This is true because of the addition of 5G NR's frequency range 2 (FR2) and the increase in available bandwidth to 100 MHz in the sub-6 GHz frequency range. This additional bandwidth is partially utilized by using longer OFDM symbols, which further increases the PAPR of OFDM. This additional bandwidth can also be used for PAPR reduction through a technique called tone reservation.

[0070] Tone reservation can allow a transmitter to utilize some otherwise idle tones to reduce the PAPR of an 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 data tones and reserved tones. In this way, tone reservation can be used without introducing any EVM or adjacent channel leakage ratio. The receiver can simply ignore the signal portion associated with the reserved tones and only decode the signal portion associated with the data tones.

[0071] Tone retention can be performed by determining a PRT that is configured to reduce the peak value of the resulting OFDM signal so that the PAPR of the resulting signal meets a threshold. The PRT can be generated using a signal-to-clipping noise ratio tone retention (SCR-TR) algorithm. The SCR-TR algorithm can be used to optimize the value of the PRT tone based at least in part on the position of the PRT tone.

[0072] A set of N transmission tones with corresponding set of tone position indices {1, ..., N} may be allocated to the UE. If Φ is a subset of {1, ..., N} corresponding to the PRT positions, the remaining transmission tone positions may be allocated to data tones with the subset of tone position indices {1, ..., N}\Φ. The frequency domain kernel P may be constructed i , so that:

[0073]

[0074] And p = iDFT(P). X can be frequency domain data. Therefore, if i∈Φ and x = iDFT(X), X i =0.

[0075] 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 consists of cyclic shifts p, p j = circshift(p,j) so that the peaks are aligned. SCR-TR also includes subtracting the scaled and shifted p from x to obtain:

[0076]

[0077] 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 appropriately, the time domain kernel p has a single significant and narrow peak. In addition, the cyclic shift p in the time domain does not affect the position of the PRT in the frequency domain, it only interferes with their phase.

[0078] In some cases, PRT position selection may be performed by randomly selecting a set of PRT indices representing PRT positions along a spectrum in the frequency domain, generating an OFDM signal based on the PRT and data tones, and determining whether the PAPR of the resulting signal satisfies a PAPR threshold. However, due to the random nature of the PRT selection for each iteration, these methods may introduce unnecessary processing, which may result in reduced performance. In addition, the selection of the PRT may not be known to the base station, and therefore will need to be signaled to the base station to facilitate decoding by the base station, thereby increasing signaling overhead.

[0079] Aspects of the techniques and apparatus described herein can facilitate PRT reservation for reducing the PAPR of a power amplifier in a UE. In some aspects, the tone reservation techniques described herein can facilitate PRT position determination based on established patterns, sequences, tables, etc. In this way, the PRT position can be determined without optimizing random PRT index selection in real time, thereby reducing the complexity of transmitter operation. This can facilitate power and time savings during transmission, thereby improving performance, reducing computational burden, etc.

[0080] In some aspects, the base station may allocate a set of transmission tones including a set of data tones and a set of PRTs to the UE. The set of transmission tones may indicate the position of the set of PRTs (the set of which may be referred to as a set of PRT positions), and the set of PRTs is arranged according to the position of the PRT sequence relative to the set of data tones (the series of which may be referred to as a set of data tone positions). In some aspects, the PRT sequence may include a pseudo-random pattern generated using a pseudo-random number generator. The pseudo-random number generator may include a linear congruential generator, a Costas array, a maximum length sequence, a golden sequence, a Golomb Ruler, etc. In some aspects, the PRT sequence may include a plurality of continuous PRTs arranged relative to a plurality of continuous data tones.

[0081] By leveraging a simple pseudo-random number generator that has been used for other applications related to 5G NR, or by using multiple consecutive PRTs arranged relative to multiple consecutive data tones, aspects of the present disclosure described herein provide a simple PRT selection that facilitates PRT position determination with little processing overhead, signaling overhead, additional programming, etc. In addition, the use of a pseudo-random number generator results in a kernel with a single narrow peak, and therefore does not have wide lobes or periodic peaks. In some aspects, the set of transmission tones may include a discrete Fourier transform spread-OFDM (DFT-s-OFDM) waveform. In some aspects, the set of transmission tones may include a cyclic prefix-OFDM (CP-OFDM) waveform (e.g., when some performance can be traded for low signaling overhead).

[0086] In some aspects, the PRTT may include multiple entries. An entry in the multiple entries may include a PRT sequence 314, one or more parameters of a pseudo-random number generator, etc. In some aspects, the multiple entries may indicate multiple pseudo-random sequences. Each entry in the multiple entries may correspond to a corresponding pseudo-random sequence in the multiple pseudo-random sequences. In some aspects, each entry may indicate an offset associated with the corresponding pseudo-random sequence, a length associated with the corresponding pseudo-random sequence, etc. In some aspects, each pseudo-random sequence in the multiple pseudo-random sequences may correspond to a set of RBs allocated to the UE, a ratio of the number of PRTs 308 in the set of PRTs 308 to the number of data tones 306 in the set of data tones 306, etc.

In some aspects, the density of the PRTs 308 in the set of PRTs 308 may be based at least in part on one or more parameters of the pseudo-random number generator, available bandwidth resources, etc.

[0088] As shown in reference numeral 316, UE 120 may generate a waveform based at least in part on the resource allocation. In some aspects, UE 120 may generate a waveform by determining an inverse discrete Fourier transform of the set of transmission tones. In some aspects, the waveform may include a CP-OFDM waveform. In some aspects, the waveform may include a DFT-s-OFDM waveform. In some aspects, a set of PRTs may be selected such that a PAPR associated with the waveform satisfies a PAPR threshold.
