FIG.4is a diagram illustrating an example400of UE subcarrier tone reservation on one or more subcarriers, in accordance with the present disclosure. In some networks, a network node may transmit a downlink transmission on a physical downlink shared channel (PDSCH) with tone reservation on one or more subcarriers based at least in part on measurement(s) of uplink signals from a UE, a request from the UE, an indication of a capability of the UE, and/or an independent determination by the network node, among other examples (e.g., as described herein).

In some aspects, the UE may be configured to communicate with the network node with a configuration for tone reservation. For example, the configuration may be common for multiple communications (e.g., for a configured grant and/or semi-persistent scheduling resources), multiple UEs connected to the network node, a beam provided by the network node, a cell provided by the network node, and/or the like.

As shown by example400, a PDSCH may include one or more reserved subcarriers (e.g., tones) on which data and/or pilots are not to be transmitted. In some aspects, the subcarriers may be empty (e.g., not having any information intended for transmission to the UE). Additionally, or alternatively, tone reservation may be applied to physical downlink control channel (PDCCH) symbols (e.g., symbols 0 and 1 inFIG.4). In some aspects, a pilot may include or may be a reference signal. In some aspects, the network node may transmit a signal that is configured to improve a PAPR for a downlink transmission on the PDSCH by using tone reservation to forego transmission of data and/or pilots on the one or more reserved subcarriers. While example400provides an example of tone reservation applied to PDSCH and/or PDCCH, in some aspects (e.g., when a UE applies tone reservation to uplink communications transmitted to a network node), tone reservation may be applied to physical uplink shared channel (PUSCH) and/or physical uplink control channel (PUCCH) symbols.

The use of tone reservation may involve significant overhead that may decrease overall throughput. For example, to enable the UE to identify which subcarriers to discard (e.g., the reserved subcarriers), the network node may indicate the frequency locations (e.g., using identifiers) of the subcarriers to the UE. These indications may consume communication, network, and power resources (e.g., bits) for the network node to transmit (e.g., in downlink control information) and for the UE to receive. Additionally, or alternatively, consumption of the network resources for the indications may decrease throughput available for data (e.g., associated with the PDSCH). In a communication where tone reservation is not used, an increase in PAPR may occur, which may degrade communications between the network node and the UE, and may negatively affect an efficiency of power amplification at the network node. Based at least in part on degradation of the communications, the UE and/or the network node may consume power, communication, network, and computing resources to detect and/or correct communication errors associated with the degradation.

In some networks, waveforms for wireless communications may be selected for use to compensate for noise within the network. For example, a network may use a time-division multiplexing (TDM) waveform, such as a discrete Fourier transform-spread orthogonal frequency-division multiplexing (DFT-s-OFDM) waveform (e.g., on a downlink), to compensate for and/or to minimize effects of phase noise. The network may use the TDM waveform based at least in part on the wireless communications using frequency bands, such as FR4, FR5, and/or sub-terahertz frequencies.

In some networks, the DFT-s-OFDM waveform may have similar characteristics to a single carrier waveform (e.g., using TDM), which may allow for a reduced PAPR. The reduced PAPR and reduced phase noise associated with the DFT-s-OFDM waveform may improve performance, power efficiency, and/or coverage of the network.

DMRSs in a DFT-s-OFDM use an entire symbol based at least in part on DFT-s-OFDM being a frequency division multiplexed (FDM) waveform (e.g., with a single carrier waveform). However, if a transmitting device transmits via multiple layers, the transmitting device may consume multiple symbols for DMRSs for different layers. For example, a transmission with two layers (e.g., two streams) may require two symbols of DMRSs. This may consume an increasing amount of network resources for each layer transmitted. In this way, TDM communications with DMRSs may have relatively high overhead.

In some networks, the transmitting device may use FDM to transmit multiple DMRSs on a single symbol (e.g., using multiple ports). However, this may remove the PAPR reduction benefit of DFT-s-OFDM and/or an FDM waveform, which may cause an increased PAPR and degraded performance.

In some aspects described herein, a network may configure a pilot symbol with pilot signaling on a first set of subcarriers and with PAPR signaling (e.g., tone reservation signaling configured to reduce the PAPR) on a second set of subcarriers. In some aspects, the pilot signaling may be associated with a first receiving device and the pilot symbol may include additional pilot signaling associated with a second receiving device. For example, the pilot symbol may include a first set of subcarriers with pilot signaling (e.g., DMRSs) for a first receiving device, a second set of subcarriers with pilot signaling for a second receiving device, and a third set of subcarriers with PAPR signaling. In some aspects, the pilot symbol may include additional sets of pilot signaling for additional receiving devices and/or additional streams and/or ports associated with a same receiving device.

Based at least in part on providing PAPR signaling on the pilot symbol, the pilot symbol may have reduced PAPR. Additionally, or alternatively, the pilot symbol may support FDM of multiple pilot signals with reduced degradation of performance from PAPR of FDM.

In some aspects, tone reservation subcarriers may be occupied with PAPR reduction signals, which are not DMRS signals. Tone reservation algorithms may not be sensitive to which subcarrier locations are assigned for the PAPR reduction. Additionally, or alternatively, tone reservation assigned subcarriers may have relatively low energy compared to DMRS resources (e.g., resource elements). DMRS pilots are not needed for every resource element (RE) based at least in part on channel estimation supporting interpolation using a distance of 2-6 REs depending on delay spread of a channel. In this way, tone reservation REs may be transmitted periodically inside a DFT-S-OFDM symbol that carries the DMRS signals.

In some aspects, the network may configure a “dummy” DMRS port on top of transmitted DMRS ports, with the dummy DMRS port having the PAPR signaling configured to keep the PAPR low. Some networks may have a limited combination of numbers of required DMRS ports, which may support pre-computation and specification of the tone reservation signal in a communication protocol.

FIG.5is a diagram of an example500associated with pilot symbols having pilot signaling and PAPR signaling, in accordance with the present disclosure. As shown inFIG.5, a transmitting device (e.g., network node110, a CU, a DU, and/or an RU) may communicate with a receiving device (e.g., UE120). In some aspects, the transmitting device and the receiving device may be part of a wireless network (e.g., wireless network100). The transmitting device and the receiving device may have established a wireless connection prior to operations shown inFIG.5. In some aspects, the transmitting device and the receiving device may communicate via MIMO communications.

As shown by reference number505, the transmitting device and the receiving device may exchange configuration information. For example, as shown by reference number505, the transmitting device may transmit the configuration information to the receiving device. In other examples, the receiving device may transmit the configuration information to the transmitting device (e.g., if the receiving device is a network node and/or the transmitting device is a UE, among other examples). In some aspects, the receiving device may receive the configuration information via one or more of RRC signaling, one or more medium access control (MAC) control elements (CEs), and/or downlink control information (DCI), among other examples. In some aspects, the configuration information may include an indication of one or more configuration parameters (e.g., already known to the receiving device and/or previously indicated by the transmitting device or other network device) for selection by the receiving device, and/or explicit configuration information for the receiving device to use to configure the receiving device, among other examples.

In some aspects, the configuration information may indicate that the receiving device is to provide a capabilities report and/or an indication of support for communicating via an FDM waveform, via a DFT-s-OFDM waveform, and/or using a pilot symbol that includes pilot signaling and PAPR signaling, among other examples. In some aspects, the configuration information may indicate a format for signaling use of the pilot symbol that includes pilot signaling and PAPR signaling. In some aspects, the configuration information may indicate one or more parameters for using the pilot symbol that includes pilot signaling and PAPR signaling.

The receiving device may configure itself based at least in part on the configuration information. In some aspects, the receiving device may be configured to perform one or more operations described herein based at least in part on the configuration information.

As shown by reference number510, the receiving device may transmit, and the transmitting device may receive, an indication of support for pilot symbols that include pilot signaling and PAPR signaling. For example, the indication of support may indicate a number of subcarriers that the receiving device supports for pilot signaling within the pilot symbol. For example, the receiving device may indicate that a minimum number of subcarriers, or a minimum ratio of subcarriers, is needed to carry the pilot signaling within the pilot symbol. Additionally, or alternatively, the receiving device may indicate a number of ports (e.g., used for pilots with different streams and/or PAPR signaling) that the pilot symbol may include and still be used as a pilot for the receiving device.

As shown by reference number515, the receiving device may receive, and the transmitting device may transmit, an indication of locations (e.g., frequency locations of associated subcarriers) of the pilot signaling and/or a configuration of the pilot signaling. For example, the receiving device may receive an indication of locations of a first set of one or more subcarriers that are to carry the pilot signaling (e.g., DMRSs signaling). The configuration of the pilot signaling may indicate a sequence used in the pilot signaling and/or power parameters of the pilot signaling, among other examples.

As shown by reference number520, the receiving device may receive, and the transmitting device may transmit, an indication of locations (e.g., frequency locations of associated subcarriers) of the PAPR signaling and/or a configuration of the PAPR signaling. For example, the receiving device may receive an indication of locations of a second set of one or more subcarriers that are to carry the PAPR signaling. The configuration of the pilot signaling may indicate a waveform and/or power parameters of the PAPR signaling (e.g., signaling configured to reduce a PAPR of the communication and/or having no data or control information or pilot sequences), among other examples.

As shown by reference number525, the receiving device may receive, and the transmitting device may transmit, a communication that includes at least one pilot symbol with pilot signaling and PAPR signaling. In some aspects, the at least one pilot symbol may include pilot signaling on a first set of one or more subcarriers and PAPR signaling on a second set of one or more subcarriers. In some aspects, the at least one pilot symbol may include additional pilot signaling (e.g., associated with an additional receiving device and/or an additional stream for the receiving device) on a third set of one or more subcarriers, etc.

In some aspects, the PAPR signaling may include signaling transmitted with different power levels at different subcarrier locations of a communication. The signaling may be configured with the different power levels at the different subcarriers such that, when the signaling is added to another part of a communication (e.g., the data and/or the pilots), a power of the communication across all subcarriers of the communication may have a reduced variation (e.g., variations between peak power levels and an average power level). In this way, the communication may have a reduced PAPR based at least in part on inserting the PAPR signaling into the communication at the second set of the one or more subcarriers. The reduced PAPR may reduce saturation of a power amplifier at a transmitting device, which may improve power efficiency and/or reduce signal clipping. Additionally, or alternatively, the reduced PAPR reduce saturation at a receiver, which may improve demodulation of the communication.

In some aspects, the communication may include an FDM communication and/or a DFT-s-OFDM communication, among other examples. For example, the communication may include single waveform data symbols and the pilot symbols. In some aspects, the pilot symbol may include the pilot signaling interleaved with the PAPR signaling. In some aspects in which multiple pilot signalings are used (e.g., associated with different ports), the pilot symbol may include subcarriers sequentially rotated (e.g., in a frequency domain) through pilot signaling for each port and the PAPR signaling. For example, the pilot symbol may have a pattern of subcarriers, described in sequence from a highest frequency to a lowest frequency subcarrier as: port 0 pilot signaling on subcarrier n, port 1 pilot signaling on subcarrier n-1, port 2 pilot signaling on subcarrier n-2, PAPR signaling on subcarrier n-3, port 0 pilot signaling on subcarrier n-4, port 1 pilot signaling on subcarrier n-5, port 2 pilot signaling on subcarrier n-6, PAPR signaling on subcarrier 7, etc.

As shown by reference number530, the receiving device may decode one or more data symbols based at least in part on the pilot signaling. In some aspects, the receiving device may use the pilot signaling (e.g., DMRSs) to perform channel estimation. In some aspects, the receiving device may interpolate between subcarriers of the pilot symbol that carry the pilot signaling to estimate a channel associated with the communication. The receiving device may use the channel estimation to attempt to decode data symbols of the communication.

As shown by reference number535, the transmitting device and the receiving device may communicate based at least in part on the pilot signaling. In some aspects, the transmitting device and the receiving device may communicate using an FDM communication and/or a DFT-s-OFDM communication, among other examples. For example, the transmitting device and the receiving device may use communications that include single waveform data symbols and the pilot symbols.

Based at least in part on providing PAPR signaling on the pilot symbol, the pilot symbol may have reduced PAPR. Additionally, or alternatively, the pilot symbol may support FDM of multiple pilot signals with reduced degradation of performance from PAPR of FDM. In this way, the transmitting device and the receiving device may conserve network resources that may have otherwise been used to communicate additional pilot symbols for individual streams and/or receiving devices.

FIG.6is a diagram of an example600associated with pilot symbols having pilot signaling and PAPR signaling, in accordance with the present disclosure. InFIG.6, a transmitting device (e.g., network node110, a CU, a DU, and/or an RU) may communicate with a receiving device (e.g., UE120) using communications that include a pilot symbol having one or more pilot signaling ports and a PAPR signaling port. In some aspects, the transmitting device and the receiving device may be part of a wireless network (e.g., wireless network100). The transmitting device and the receiving device may have established a wireless connection prior to operations shown inFIG.6.

As shown inFIG.6, the communication may include one or more pilot symbols605and one or more sets of data symbols610. The communication may include a number of pilot symbols that is based at least in part on channel conditions (e.g., associated with changing channel conditions that may require additional pilot density within the communication). As shown, the communication may include two pilot symbols605, and this is a non-limiting example. The communication may include a single pilot symbol605, three pilot symbols, or more pilot symbols.

The pilot symbols605include a first pilot symbol port (P1), a second pilot symbol port (P2), a third pilot symbol port (P3), and PAPR signaling. In some aspects, the communication may include pilot signaling in each of the pilot signal ports or in only a portion of the pilot signal ports. For example, the communication may be configured with a number of pilot signal ports whether or not each of the pilot signal ports is in use. As shown inFIG.6, the pilot symbol may interleave resources for the pilot signal ports and the PAPR signaling.

In some aspects, a first pilot symbol605and a second pilot symbol605may include a same set of pilot signal ports and PAPR signaling. In some aspects, the first pilot symbol605may include a first set of pilot signal ports, and the second pilot symbol605may include a second set of pilot signal ports. In some aspects, the PAPR signaling occupies a pilot signal port as a dummy port. In this way, the PAPR signaling may be included on each pilot symbol605or may be included on a subset of pilot symbols605.

The receiving device may use one or more ports of pilot signaling to estimate a channel of the communication. The receiving device may use the channel estimate to decode the data symbols610using interpolation and/or extrapolation.
