[0003] Aspects of the present disclosure generally relate to wireless communication and relate to techniques and apparatuses for power headroom reporting for dynamic waveform switching. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ multiple access techniques capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access techniques 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 / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink communication and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device - to - device communication, such as via local links (e.g., sidelink (SL), Wireless Local Area Network (WLAN) link, and / or Wireless Personal Area Network (WPAN) link, etc.).

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at the urban, national, regional, or global level. New Radio (NR) (which may also be referred to as 5G) is an enhanced set of the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink, CP-OFDM or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, Multiple Input Multiple Output (MIMO) antenna technology, and carrier aggregation to improve spectral efficiency, reduce costs, improve services, utilize new spectra, and better integrate with other open standards.

[0027] The various aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Those skilled in the art will understand that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. In addition, the scope of the present disclosure is intended to cover such apparatus or methods implemented using other structures, functions, or combinations of structures and functions in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

[0028] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0029] Although terms generally associated with 5G or new radio (NR) radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0030] Figure 1FIG. is an illustration of an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network or elements of a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), or other entities. The network node 110 is an example of a network node that communicates with the UE 120. As shown, the network node 110 may include one or more network nodes. For example, the network node 110 may be an aggregated network node, which means that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes, such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs).

[0031] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a disaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. For example, the network node 110 may include an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, an RU, a CU, a mobility element of the network, a core network node, a network element, network equipment, a RAN node, or a combination thereof. In some examples, the network nodes 110 may be interconnected with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network via various types of fronthaul, midhaul, and / or backhaul interfaces, such as a direct physical connection, an air interface, or a virtual network.

[0032] In some examples, network node 110 may provide communication coverage for a specific geographical area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of network node 110 or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographical area (e.g., with a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographical area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographical area (e.g., a residence) and may allow restricted access by a UE 120 associated with that femto cell (e.g., a UE 120 in a Closed Subscriber Group (CSG)). The network node 110 for a macro cell may be referred to as a macro network node. The network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. In Figure 1 the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographical area of a cell may move according to the location of a moving network node 110 (e.g., a mobile network node).

[0033] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, the "base station" or "network node" may refer to a CU, a DU, an RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a single device configured to perform one or more functions, such as those described herein in connection with network node 110. In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located at the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function among base station functions, rather than another base station function. In this way, a single device may include more than one base station.

[0034] Wireless network 100 may include one or more relay stations. A relay station is a network node that receives a transmission of data from an upstream node (e.g., network node 110 or UE 120) and conveys the transmission of data to a downstream node (e.g., UE 120 or network node 110). A relay station may be a UE 120 capable of relaying transmissions for other UEs 120. In Figure 1 the example shown, network node 110d (e.g., a relay network node) may communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. A network node 110 that relays communication may be referred to as a relay station, a relay base station, a relay network node, a relay node, or a relay, etc.

[0035] Wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes 110 may have different transmission power levels, different coverage areas, or different impacts on interference in wireless network 100. For example, a macro network node may have a high transmission power level (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmission power levels (e.g., 0.1 watt to 2 watts).

[0036] The network controller 130 can be coupled to or communicate with a set of network nodes 110 and can provide coordination and control for these network nodes 110. The network controller 130 can communicate with the network nodes 110 via a fronthaul communication link or a midhaul communication link. The network nodes 110 can also communicate directly with each other or indirectly via a wireless fronthaul communication link or a wired fronthaul communication link. In some aspects, the network controller 130 can be a CU or a core network device, or can include a CU or a core network device.

[0037] UEs 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. The UEs 120 can include, for example, access terminals, terminals, mobile stations, or subscriber units. The UEs 120 can be cellular phones (e.g., smartphones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablet devices, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices, biometric devices, wearable devices (e.g., smartwatches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings or smart bracelets)), entertainment devices (e.g., music devices, video devices, or satellite radios), in-vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, UE functions of network nodes, or any other suitable devices configured to communicate via wireless or wired media.

[0038] Some UEs 120 can be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs or eMTC UEs can include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags, which can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 can be considered Internet of Things (IoT) devices, or can be implemented as narrowband IoT (NB-IoT) devices. Some UEs 120 can be considered customer premises equipment. The UEs 120 can be included inside a housing that houses components of the UEs 120, such as processor components or memory components. In some examples, the processor components and the memory components can be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, or electrically coupled.

[0039] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. The RAT can also be referred to as a radio technology or an air interface. The frequency can also be referred to as a carrier or a frequency channel. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0040] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using the network node 110 as an intermediary for communicating with each other). For example, the UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), or a mesh network. In such examples, the UE 120 can perform scheduling operations, resource selection operations, or other operations described elsewhere in this document as being performed by the network node 110.

[0041] The devices of the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, or channels by frequency or wavelength. For example, the devices of the wireless network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Although a part of FR1 is greater than 6 GHz, in various documents and articles, FR1 is typically (interchangeably) referred to as the "sub-6 GHz" band. Regarding FR2, a similar naming issue sometimes occurs, which is typically (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified by the International Telecommunication Union (ITU) as the "millimeter wave" band.

[0042] The frequency between FR1 and FR2 is generally referred to as the mid-band frequency. Recent 5G NR studies have identified the operating bands for these mid-band frequencies as frequency range designations FR3 (7.125 GHz → 24.25 GHz). The bands falling within FR3 can inherit FR1 characteristics or FR2 characteristics, and thus the characteristics of FR1 or FR2 can be effectively extended to the mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz → 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0043] Considering these examples, unless otherwise specifically stated, if the term "below 6 GHz" is used herein, it can generally represent a frequency that can be less than 6 GHz, a frequency within FR1, or a frequency that can include mid-band frequencies. In addition, unless otherwise specifically stated, if the term "millimeter wave" is used herein, it can broadly represent a frequency that can include mid-band frequencies, a frequency within FR2, FR4, FR4-a, or FR4-1, or FR5, or a frequency within the EHF band. It is conceivable that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, or FR5) can be modified, and the techniques described herein apply to those modified frequency ranges.

[0044] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 can send a power headroom report to a network node, the power headroom report including a field indicating information associated with a first waveform and a second waveform, the second waveform and the first waveform having a common set of transmission parameters; and communicate with the network node based on the power headroom report. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0045] In some aspects, network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 can receive a power headroom report from a UE, the power headroom report including a field indicating information associated with a first waveform and a second waveform, the second waveform and the first waveform having a common set of transmission parameters; and communicate with the UE based on the power headroom report. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0046] As indicated above,Figure 1 is provided as an example. Other examples may differ from the example Figure 1 described.

[0047] Figure 2 is a diagram illustrating Example 200 in which a network node 110 communicates with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of Example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0048] At network node 110, transmit processor 220 may receive data destined for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may use one or more channel quality indicators (CQIs) received from UE 120 to select one or more modulation and coding schemes (MCSs) for that UE 120. Network node 110 may use the MCS selected for UE 120 to process (e.g., encode and modulate) the data for UE 120 and may provide data symbols to UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, or upper layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRSs) or demodulation reference signals (DMRSs)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, or reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a through 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 may use the corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may also use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, or up-convert) the output sample stream to obtain a downlink signal. Modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a through 234t).

[0049] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 or other network nodes 110, and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may condition (e.g., filter, amplify, down-convert, or digitize) the received signal using the corresponding demodulator component to obtain input samples. Each modem 254 may further process the input samples (e.g., for OFDM) using the demodulator component to obtain received symbols. The MIMO detector 256 may obtain the received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide the decoded data for the UE 120 to the data sink 260, and may provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, or CQI parameters, etc. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0050] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0051] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or may be included in the following: one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. The antenna panel, antenna group, set of antenna elements, or antenna array may include one or more antenna elements (in a single housing or multiple housings), a coplanar set of antenna elements, a non-coplanar set of antenna elements, or one or more antenna elements coupled to one or more transmit or receive components (such as Figure 2 one or more components) of.

[0052] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-coded by the TX MIMO processor 266 when applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller / processor 280) and the memory 282 to perform aspects of any of the processes described herein (e.g., with reference to Figures 5 to 9 ).

[0053] At the network node 110, the uplink signal from the UE 120 or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., the demodulator component of the modem 232, shown as DEMOD), detected by the MIMO detector 236 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted via the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller / processor 240) and the memory 242 to perform aspects of any of the processes described herein (e.g., with reference to Figures 5 to 9 ).

[0054] In some aspects, the controller / processor 280 can be a component of a processing system. A processing system can generally be a system or series of machines or components that receive inputs and process the inputs to produce outputs (which can be passed to other systems or components such as the UE 120). For example, the processing system of the UE 120 can be a system that includes various other components or sub-components of the UE 120.

[0055] The processing system of the UE 120 can interface with one or more other components of the UE 120, process information (such as inputs or signals) received from one or more other components, or output information to one or more other components. For example, a chip or modem of the UE 120 can include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, transmitting, or providing information. In some examples, the first interface can be an interface between the processing system of the chip or modem and a receiver, such that the UE 120 can receive information or signal inputs and pass the information to the processing system. In some examples, the second interface can be an interface between the processing system of the chip or modem and a transmitter, such that the UE 120 can transmit information output from the chip or modem. One of ordinary skill in the art will readily recognize that the second interface can also obtain or receive information or signal inputs and the first interface can also output, transmit, or provide information.

[0056] In some aspects, the controller / processor 240 can be a component of a processing system. A processing system can generally be a system or series of machines or components that receive inputs and process the inputs to produce outputs (which can be passed to other systems or components such as the network node 110). For example, the processing system of the network node 110 can be a system that includes various other components or sub-components of the network node 110.

[0057] The processing system of network node 110 can interface with one or more other components of network node 110, process information (such as inputs or signals) received from one or more other components, or output information to one or more other components. For example, a chip or modem of network node 110 can include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, transmitting, or providing information. In some examples, the first interface can be an interface between the processing system of the chip or modem and a receiver, such that network node 110 can receive information or signal inputs and pass the information to the processing system. In some examples, the second interface can be an interface between the processing system of the chip or modem and a transmitter, such that network node 110 can transmit the information output from the chip or modem. Those of ordinary skill in the art will readily recognize that the second interface can also obtain or receive information or signal inputs, and the first interface can also output, transmit, or provide information.

[0058] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120, or Figure 2 any other component can perform one or more techniques associated with power headroom reporting for dynamic waveform switching, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, or Figure 2 any other component (or combination of components) can execute or direct, for example, Figure 6 process 600, Figure 7 process 700, and / or the operation of other processes as described herein. Memories 242 and 282 can store data and program code for network node 110 and UE 120, respectively. In some examples, memories 242 and 282 can include non-transitory computer-readable media storing one or more instructions (e.g., code or program code) for wireless communication. For example, when the one or more instructions are executed by one or more processors of network node 110 or UE 120 (e.g., directly executed, or after compilation, conversion, or interpretation), the one or more processors, UE 120, or network node 110 can execute or direct, for example, Figure 6 process 600, Figure 7 process 700, and / or the operation of other processes as described herein. In some examples, executing the instructions can include running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions, etc.

[0059] In some aspects, UE 120 includes: components for sending a power headroom report to a network node, the power headroom report including a field indicating information associated with a first waveform and a second waveform, the second waveform and the first waveform having a common set of transmission parameters; and / or components for communicating with the network node based on the power headroom report. The components for UE 120 to perform the operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0060] In some aspects, network node 110 includes: components for receiving a power headroom report from a UE, the power headroom report including a field indicating information associated with a first waveform and a second waveform, the second waveform and the first waveform having a common set of transmission parameters; and / or components for communicating with the UE based on the power headroom report. The components for network node 110 to perform the operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0061] Although Figure 2 the boxes in are illustrated as different components, the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by controller / processor 280 or under the control of the controller / processor.

[0062] In some aspects, a single processor may perform all the functions described as being performed by the one or more processors. In some aspects, the one or more processors may perform a set of functions jointly. For example, a first set of (one or more) processors among the one or more processors may perform a first function described as being performed by the one or more processors, and a second set of (one or more) processors among the one or more processors may perform a second function described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. References to "one or more processors" should be understood to refer to any one or more of the processors described in conjunction with Figure 2 Any one or more of the memories of the corresponding device, such as those described in conjunction withFigure 2 The described memories. For example, functions described as being performed by one or more memories may be performed by the same subset or different subsets of the one or more memories.

[0063] As indicated above, Figure 2 is provided as an example. Other examples may be different from the examples described with respect to Figure 2 the examples described.

[0064] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, network nodes, network entities, mobility elements of the network, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in an aggregated or disaggregated architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also referred to as a stand-alone base station or monolithic base station) or a disaggregated base station. A "network entity" or "network node" can refer to a disaggregated base station or one or more units of a disaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0065] An aggregated base station (e.g., an aggregated network node) can be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node (e.g., within a single device or unit). A disaggregated base station (e.g., a disaggregated network node) can be configured to utilize a protocol stack physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually spread across one or more other network nodes. A DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, such as a virtual central unit (VCU), virtual distributed unit (VDU), or virtual radio unit (VRU), etc.

[0066] Base station type operations or network design may consider the aggregation characteristics of base station functionality. For example, a split base station can be utilized in an IAB network, an open radio access network (O-RAN, such as a network configuration advocated by the O-RAN Alliance), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A split base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which can achieve flexibility in network design. Each unit of the split base station can be configured for wired or wireless communication with at least one other unit of the split base station.

[0067] Figure 3 FIG. 4 is a diagram illustrating an example split base station architecture 300 according to the present disclosure. The split base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 through one or more split control units (such as a near RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a respective midhaul link, such as through an F1 interface. Each DU in the DUs 330 may communicate with one or more RUs 340 via a respective fronthaul link. Each RU in the RUs 340 may communicate with one or more UEs 120 via a respective radio frequency (RF) access link. In some specific implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0068] Each unit (including the CU 310, DU 330, RU 340) and the near RT RIC 325, non-RT RIC 315, and SMO framework 305 may include one or more interfaces or be coupled to the one or more interfaces, which are configured to receive or transmit signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each unit or an associated processor or controller that provides instructions to one or more communication interfaces of the respective unit may be configured to communicate with one or more of the other units via the transmission medium. In some examples, each unit may include a wired interface and a wireless interface, the wired interface being configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, and the wireless interface may include a receiver, a transmitter, or a transceiver (such as an RF transceiver), the receiver, transmitter, or transceiver being configured to receive signals or transmit signals to one or more of the other units via a wireless transmission medium or perform both.

[0069] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to signal with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit → user plane (CU-UP) functionality), control plane functionality (e.g., central unit → control plane (CU-CP) functionality), or a combination thereof. In some embodiments, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units may communicate bidirectionally with the CU-CP units via an interface such as the E1 interface. As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0070] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of the radio link control (RLC) layer, media access control (MAC) layer, and one or more higher physical (PHY) layers, at least in part, according to a functional split (such as the functional split defined by 3GPP). In some aspects, one or more of the higher PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more lower PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to signal with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0071] Each RU 340 can implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 can correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc.) based on functional split (such as the functional split defined by 3GPP), such as lower layer functional split. In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communication with one or more UEs 120. In some specific implementations, the real-time aspects and non-real-time aspects of communicating with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration can enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0072] The SMO framework 305 can be configured to support the deployment and orchestration of RANs for non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, and these dedicated physical resources can be managed via an operation and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements can include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 can communicate with the hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the o1 interface. Additionally, in some specific implementations, the SMO framework 305 can communicate directly with each RU in one or more RUs 340 via the corresponding o1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0073] The non-RT RIC 315 can be configured to include logic functions that can implement non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325 (such as via the A1 interface). The near-RT RIC 325 can be configured to include logic functions that can implement near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via the E2 interface), which connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB to the near-RT RIC 325.

[0074] In some specific implementations, to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or from network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns of performance and employ an AI / ML model to perform corrective actions through the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0075] As indicated above, Figure 3 is provided as an example. Other examples may be different from the examples described with respect to Figure 3 described.

[0076] Figure 4 is a diagram illustrating Example 400 of physical channels and reference signals in a wireless network according to the present disclosure. As Figure 4 shown, the downlink channels and downlink reference signals can carry information from the network node 110 to the UE 120, and the uplink channels and uplink reference signals can carry information from the UE 120 to the network node 110.

[0077] As shown, the downlink channel may include a Physical Downlink Control Channel (PDCCH) carrying downlink control information (DCI), a Physical Downlink Shared Channel (PDSCH) carrying downlink data, a Physical Broadcast Channel (PBCH) carrying system information, and so on. In some aspects, PDSCH communication may be scheduled by PDCCH communication. As further shown, the uplink channel may include a Physical Uplink Control Channel (PUCCH) carrying uplink control information (UCI), a Physical Uplink Shared Channel (PUSCH) carrying uplink data, or a Physical Random Access Channel (PRACH) for initial network access, and so on. In some aspects, UE 120 may send an acknowledgement (ACK) or negative acknowledgement (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in the UCI on the PUCCH and / or PUSCH.

[0078] As further shown, the downlink reference signals may include Synchronization Signal Blocks (SSBs), Channel State Information (CSI) Reference Signals (CSI-RSs), DMRSs, Positioning Reference Signals (PRSs), or Phase Tracking Reference Signals (PTRSs), etc. Also as shown, the uplink reference signals may include Sounding Reference Signals (SRSs), DMRSs, or PTRSs, and so on.

[0079] The SSB may carry information for initial network acquisition and synchronization, such as the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), the PBCH, and the PBCH DMRS. The SSB is sometimes referred to as a Synchronization Signal / PBCH (SS / PBCH) block. In some aspects, the network node 110 may transmit multiple SSBs on multiple corresponding beams, and the SSBs may be used for beam selection.

[0080] The CSI-RS may carry information for downlink channel estimation (e.g., downlink CSI acquisition), which may be used for scheduling, link adaptation, or beam management, etc. The network node 110 may configure a CSI-RS set for the UE 120, and the UE 120 may measure the configured CSI-RS set. At least partially based on the measurement, the UE 120 may perform channel estimation and may report channel estimation parameters (e.g., in a CSI report) to the network node 110, such as the Channel Quality Indicator (CQI), the Precoding Matrix Indicator (PMI), the CSI-RS Resource Indicator (CRI), the Layer Indicator (LI), the Rank Indicator (RI), or the Reference Signal Received Power (RSRP), etc. The network node 110 may use the CSI report to select transmission parameters for downlink communication with the UE 120, such as the number of transmission layers (e.g., rank), the precoding matrix (e.g., precoder), the Modulation and Coding Scheme (MCS), or a refined downlink beam (e.g., using a beam refinement procedure or a beam management procedure), etc.

[0081] The DMRS can carry information for estimating a radio channel to demodulate an associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of the DMRS can be specific to the physical channel for which the DMRS is used for estimation. The DMRS is UE-specific, can be beamformed, can be restricted to the scheduled resources (e.g., instead of being transmitted over a wideband), and can be transmitted only when necessary. As shown in the figure, the DMRS is used for both downlink communication and uplink communication.

[0082] The PTRS can carry information for compensating oscillator phase noise. Generally, phase noise increases as the oscillator carrier frequency increases. Therefore, the PTRS can be utilized at high carrier frequencies (such as millimeter-wave frequencies) to mitigate phase noise. The PTRS can be used to track the phase of the local oscillator and to achieve suppression of phase noise and common phase error (CPE). As shown in the figure, the PTRS is used for both downlink communication (e.g., on the PDSCH) and uplink communication (e.g., on the PUSCH).

[0083] The PRS can carry information for implementing timing or ranging measurements of the UE 120 based on the signals transmitted by the network node 110 to improve the observed time difference of arrival (OTDOA) positioning performance. For example, the PRS can be a pseudo-random quadrature phase shift keying (QPSK) sequence mapped in a diagonal pattern with frequency offset and time offset to avoid collision with cell-specific reference signals and control channels (e.g., PDCCH). Generally speaking, the PRS can be designed to improve the detectability of the UE 120, which may need to detect downlink signals from multiple neighboring network nodes to perform OTDOA-based positioning. Therefore, the UE 120 can receive the PRS from multiple cells (e.g., the reference cell and one or more neighboring cells), and can report the reference signal time difference (RSTD) based on the OTDOA measurement results associated with the PRS received from multiple cells. In some aspects, the network node 110 can then calculate the location of the UE 120 based on the RSTD measurement results reported by the UE 120.

[0084] The SRS may carry information for uplink channel estimation, which can be used for scheduling, link adaptation, precoder selection, beam management, etc. The network node 110 may configure one or more SRS resource sets for the UE 120, and the UE 120 may transmit SRS on the configured SRS resource sets. The SRS resource sets may have a configured purpose, such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operations, uplink beam management, etc. The network node 110 may measure the SRS, perform channel estimation at least partially based on these measurement results, and use the SRS measurement results to configure communication with the UE 120.

[0085] As indicated above, Figure 4 is provided as an example. Other examples may be different from the examples described with respect to Figure 4 the example described.

[0086] In some communication systems, the UE may communicate with the network node using one or more different types of waveforms. For example, the UE may communicate using the DFT-s-OFDM waveform or the CP-OFDM waveform. Each waveform may be associated with different characteristics. For example, the CP-OFDM waveform may support MIMO communication, which may not be supported when using the DFT-S-OFDM waveform. As another example, the DFT-S-OFDM waveform may support a higher transmit power than the CP-OFDM waveform. This may occur because the CP-OFDM waveform may be associated with a larger power backoff at the input of the power amplifier than the power backoff used for the DFT-S-OFDM waveform.

[0087] The network node may receive a power headroom report regarding the waveform. For example, the network node may receive information from the UE about a set of channel characteristics observed using a specific waveform. The power headroom report may be configured on a per-cell group basis using one or more triggers that identify conditions (such as periodicity, timers, or power change thresholds) that, when met, will trigger the transmission of the power headroom report. The power headroom report may include a set of fields for identifying the power headroom (e.g., the first 6 bits), the maximum power P cmax (e.g., the next 6 bits), the maximum power exposure (MPE) indicator (e.g., a bit indicator of whether MPE is being reported), or the MPE value (e.g., a 2-bit indicator), etc. Additional details regarding the power headroom report and P cmax reporting are described in 3GPP Technical Specification (TS) 38.331 version 17.2.0, 3GPP TS 38.321 version 17.2.0, 3GPP TS 38.133 version 17.7.0, and 3GPP TS 38.101 version 17.7.0.

[0088] In some scenarios, it may be beneficial for a network node and a UE to switch waveforms. For example, switching waveforms (e.g., between DFT-S-OFDM and CP-OFDM) may enable the use of multiple layers or an increase in transmit power. In some scenarios, this may enable communication at a higher throughput or with greater reliability. However, to determine whether to switch waveforms, a network node may use information about the power headroom for using different waveforms. In other words, when the network node and the UE are communicating using a first waveform, the decision about whether to switch to a second waveform may be at least partially based on the power headroom that would occur if the network node and the UE were using the second waveform. However, the power headroom report includes information about the first waveform rather than the second waveform.

[0089] Some aspects described herein may implement a power headroom report for wavelength switching. For example, a UE may include in the power headroom report information about the waveforms to which the UE and the network node may switch. Additionally or alternatively, the UE may include in the power headroom report information associated with a first waveform (e.g., the first waveform that the UE is using) and a second waveform, where the second waveform and the first waveform have a common set of transmission parameters (e.g., the common set of transmission parameters to which the UE may switch). In such a case, the network node may use the power headroom report to determine whether to switch to the second waveform and / or one or more communication parameters to use when using the second waveform. In this way, the UE and the network node improve dynamic wavelength switching, thereby increasing throughput or reliability, etc.

[0090] Figure 5 is a diagram illustrating example 500 associated with a power headroom report for dynamic waveform switching according to the present disclosure. As Figure 5 shown, network node 110 and UE 120 may communicate with each other.

[0091] As Figure 5 further indicated by reference numeral 505 in, network node 110 and UE 120 may communicate to trigger a power headroom (PHR) report and / or a waveform switch.

[0092] In some aspects, network node 110 may trigger a power headroom report. For example, network node 110 may send DCI with a PUSCH grant to request UE 120 to use the PUSCH grant to send a power headroom report. In such a case, the DCI may include a bit indicator associated with triggering an aperiodic power headroom report. Additionally or alternatively, the DCI may have a set of fields with a format that UE 120 may interpret as triggering an aperiodic power headroom report.

[0093] Additionally or alternatively, the UE 120 may trigger a power headroom report at least in part based on a triggering condition being met. For example, when the UE 120 transmits power within a threshold amount of the maximum power (e.g., P powerClass value or P cmax value), the UE 120 may determine to transmit a power headroom report. Additionally or alternatively, when the UE 120 receives a PUSCH allocation for single-layer transmission that is less than a threshold resource block (RB) allocation, the UE 120 may determine to transmit a power headroom report. Additionally or alternatively, after a waveform switch, the UE 120 may transmit a power headroom report. For example, when the UE 120 transmits a power headroom report and the UE 120 and the network node 110 switch waveforms from a first waveform and a second waveform, and the second waveform and the first waveform have a common set of transmission parameters, the UE 120 may transmit a power headroom report for the second waveform (e.g., which may trigger a switch back to the first waveform or a switch to a new third waveform).

[0094] In some aspects, the UE 120 may have a triggering condition related to which waveform the UE 120 and the network node 110 are using. For example, when the UE 120 and the network node 110 use CP-OFDM, the UE 120 may trigger a power headroom report when the transmission power is within a first threshold amount of the maximum value. In contrast, when the UE 120 and the network node 110 use DFT-S-OFDM, the UE 120 may trigger a power headroom report when the transmission power exceeds a second threshold from the maximum value. Similarly, one or more parameters of the power headroom report (such as phr-Tx-PowerFactorChange) may be at least in part based on which waveform is being used. In some aspects, the triggering condition is a combination of multiple factors (such as power factor change and headroom). In some aspects, the triggering condition is a change relative to a previous measurement, such as if the power headroom has changed by a threshold amount relative to a previously reported power headroom. In some aspects, the triggering condition may apply to different formats of power headroom reports. For example, the above triggering conditions may apply to power headroom reports for dynamic waveform switching (e.g., having fields related to both the first waveform and the second waveform) or to other types of power headroom reports (e.g., the above power headroom reports that only include fields related to the current waveform).

[0095] In some aspects, the UE 120 may calculate one or more values of the power headroom report. For example, for a PUSCH transmission occasion i, an active uplink bandwidth part b of a carrier f of a serving cell c, the UE 120 may calculate a type 1 power headroom report at least in part based on the following equation:

[0096]

[0097] where PH represents the power headroom in decibels (dB), P CMAXb，f,c is the maximum configured power, is the open-loop power control transmit power, α b，fc is the fractional path loss compensation parameter, PL b,f，c is the path loss value, and f b，f，c is the cumulative transmit power control (TPC) command parameter. In this case, UE 120 may determine P CMAX,bf，c at least in part based on the power management maximum power reduction (P-MPR) value and / or the back-off value of the current waveform. For a new waveform, UE 120 may assume an MPR value corresponding to the type of the new waveform. UE 120 may determine the nominal PUSCH power P O_NOMNAL_PUSCH for the power headroom of both the current waveform and the new waveform and the actual PUSCH power P O_UE_PUSCH of the UE to determine Similarly, UE 120 may use the same α b，f，c parameter, PL b，f，c parameter, and f b，f，c to determine the power headroom values of the current waveform and the new waveform.

[0098] As Figure 5 further illustrated by reference numeral 510 in the accompanying drawings, UE 120 may send a power headroom report for the first waveform and the second waveform, and the network node 110 may receive the power headroom report. In these aspects, UE 120 may use the power headroom report to trigger waveform switching. For example, when UE 120 is triggered to send a power headroom report, UE 120 may set a bit indicator in the power headroom report to indicate a request for waveform switching.

[0099] In some aspects, the power headroom report may include one or more sets of fields. For example, the power headroom report may include a set of fields associated with the second waveform to which UE 120 and the network node 110 are to switch. Additionally or alternatively, the power headroom report may include information related to the first waveform. For example, the power headroom report may include a first set of fields associated with fields identifying characteristics associated with the first waveform and a second set of fields associated with fields identifying characteristics associated with the second waveform. In some aspects, the set of fields related to the second waveform may have a specific structure. For example, UE 120 may include a field in the power headroom report for reporting the power headroom or P cmax value. In this case, as described above, the field may be a 6-bit field for conveying the power headroom value or an indicator from which the network node 110 may derive the power headroom value.

[0100] In some aspects, the power headroom report may have a specific type of mapping between a set of fields and waveforms. For example, the UE 120 and the network node 110 may map a first set of fields in the power headroom report to the current waveform, and map a second set of fields in the power headroom report to a different waveform that the UE 120 and the network node 110 are to switch to. In this case, regardless of the respective types of the first waveform and the second waveform, the first waveform may be mapped to the first set of fields, and the second waveform may be mapped to the second set of fields. Alternatively, the UE 120 and the network node 110 may have a fixed mapping from waveform types to sets of fields. In this case, the UE 120 may map a first waveform type to the first set of fields and map a second waveform type to the second set of fields (e.g., regardless of whether the first waveform type or the second waveform type is the current waveform or a new waveform to be switched to).

[0101] In some aspects, the UE 120 may determine whether to use a power headroom report format that enables including information related to a second waveform (e.g., the waveform that the UE 120 and the network node 110 are to switch to). For example, the UE 120 may determine to use a first power headroom format when dynamic waveform switching (DWS) is disabled (e.g., only the report of the current waveform is configured for this first power headroom format), and use a second power headroom format when DWS is enabled (e.g., the reports of the current waveform and the new waveform are configured for this second power headroom format).

[0102] In some aspects, the UE 120 may determine one or more values to include in a set of fields related to a second waveform that the UE 120 and the network node 110 are to switch to. For example, the UE 120 may use a common set of transmission parameters to calculate the values of a first set of fields (e.g., related to a first current waveform) and a second set of fields (e.g., related to a second new waveform). Alternatively, the UE 120 may use different transmission parameters to calculate the values of the first set of fields and the second set of fields. In some aspects, when the set of transmission parameters used for the first waveform is incompatible with the second waveform, the UE 120 may skip reporting for the second waveform, or may report null values or null code points for the second waveform. Additionally or alternatively, the UE 120 may report default values at least partially based on the lack of compatibility of the transmission parameters.

[0103] In some aspects, the UE 120 may report power headroom on a carrier different from the carrier used for the first waveform and to be used for the second waveform. For example, when reference PUSCH transmission is enabled, the UE 120 may report a power headroom report related to the waveform on the second carrier on the first carrier (e.g., using virtual PUSCH transmission). In this case, the UE 120 may use the format of the power headroom report associated with the reports for both the current waveform and the new waveform at least in part based on enabling DWS on the second carrier. If DWS is enabled on the second carrier, the UE 120 may use a first set of fields to report the current waveform in the second carrier. Alternatively, if DWS is not enabled for the second carrier, the first set of fields in the power headroom report may be mapped to the first waveform type, and the second set of fields in the power headroom report may be mapped to the second waveform type. In other words, whether the mapping is at least in part based on the waveform type or which waveform is currently used may be based on whether DWS is enabled for the second carrier.

[0104] In some aspects, the UE 120 may set the values of the fields of the power headroom report, and the network node 110 may interpret the fields of the power headroom report at least in part based on a set of conditions. For example, when DWS is enabled and a set of scheduling parameters is configured, the UE 120 and the network node 110 may perform a conditional reinterpretation of the fields of the power headroom report. In this case, the set of scheduling parameters may include whether single-layer transmission is configured, whether the frequency-domain resource allocation (FDRA) (e.g., the number of RBs) is compatible with DFT-S-OFDM communication (e.g., the number of allocated RBs has the form 2 x 3 y 5 z ), whether CP-OFDM is used for transmission, or whether the number of RBs is less than a threshold, etc. When one or more of the scheduling parameters in the set of scheduling parameters are met, the UE 120 and the network node 110 may reinterpret the 6-bit field of the power headroom report by splitting it into 2 sub-fields of K bits and M bits respectively (K + M = 6). In this case, the first K-bit field may convey the power headroom for the current waveform, and the second M-bit field may convey the differential power headroom value. In other words, the second M-bit field may indicate the incremental value ΔPH of the power headroom for the new waveform relative to the power headroom of the current waveform according to the following equation:

[0105] ΔPH = PH dftsofdm - PH cpofdm ,

[0106] where ΔPH is the offset value indicated in the second M-bit field, PH dftsofdm is the power headroom for the DFT-S-OFDM waveform, PH cpofdmis for the power headroom of the CP - OFDM waveform, and the K bits include an indicator of either PH dftsifdm or PH cpofdm among others.

[0107] In some aspects, the UE 120 may use the same format for power headroom reporting related to a single waveform (e.g., in a non - DWS scenario) and power headroom reporting related to the current waveform and a new waveform (e.g., in a DWS scenario). In such a case, the network node 110 may infer that the 6 - bit field of the power headroom report includes a differential power headroom value (e.g., to report the power headroom for the current waveform and the new waveform in a single field), as described above. For example, when the UE 120 reports in the UE capability report the additional power available for DFT - S - OFDM relative to CP - OFDM, the network node 110 may infer that the UE 120 is using the differential power headroom value in the 6 - bit field of the power headroom report. Additionally or alternatively, the network node 110 may determine how to interpret the 6 - bit field at least in part based on the RB allocation and / or the position of the RB allocation in the frequency band. At least in part based on the power headroom report, the network node 110 may determine the additional power of the UE 120 for DFT - S - OFDM relative to CP - OFDM.

[0108] As Figure 5 further shown by reference numeral 515 in the figure, the UE 120 and the network node 110 may switch to using a second waveform. For example, the UE 120 and the network node 110 may communicate to optionally switch to using the second waveform at least in part based on the information included in the power headroom report. In such a case, when DWS is enabled and the UE 120 sends a power headroom report with information related to the second waveform, the network node 110 may determine the waveform switch and may communicate with the UE 120 (e.g., send an indication to the UE 12) to indicate the waveform switch. In this way, the network node 110 and the UE 120 may improve reliability or throughput by switching waveforms. In some aspects, at least in part based on the power headroom report, the network node 110 may determine not to switch waveforms.

[0109] As Figure 5As further shown by reference numeral 520 in the accompanying drawings, the UE 120 and the network node 110 may communicate based on a power headroom report. For example, the UE 120 and the network node 110 may use a second waveform and transmit and receive at a transmit power determined at least in part based on the power headroom report. In such a case, the second waveform and the transmit power may be based on or at least in part based on the power headroom report by using a value from the power headroom report to identify a corresponding transmit power that is a result of an equation or an entry from a look-up table, etc. Additionally or alternatively, when the network node 110 and the UE 120 determine not to switch waveforms (e.g., at least in part based on the power headroom report), the network node 110 and the UE 120 may communicate using a first waveform.

[0110] As indicated above, Figure 5 is provided as an example. Other examples may be different from the example described with respect to Figure 5 the example.
