Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) can establish a wireless connection with a network entity using a set of symbols per transmit time interval (TTI) for orthogonal frequency division multiplexing (OFDM) communication, where each symbol in the set of symbols can correspond to a fast Fourier transform (FFT) window and can include a guard interval (GI) portion and a data portion within the FFT window. In some examples, the UE can receive a control message indicating at least one parameter associated with a power offset between a data signal of the set of symbols and a reference signal of the set of symbols associated with the data signal. Thus, the UE can communicate the data signal and the reference signal with the network entity according to an indicated power offset using the set of symbols.

[0002] This patent application claims priority to U.S. patent application No. 17 / 853,695, filed by Saggar et al. on June 29, 2022, entitled “SIGNALING APOWER OFFSET BETWEEN REFERENCE AND DATATONES,” which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following relates to wireless communications including signaling a power offset between a reference tone and a data tone. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communication for a communication device, which may be referred to as a user equipment (UE). Summary of the invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support signaling of power offsets between reference tones and data tones. For example, the described techniques provide for network entities and user equipment (UE) to communicate additional signaling to clarify power offsets between different symbol types for channel estimation. For example, the network entity may send a control signal (e.g., via downlink control information (DCI), a medium access control-control element (MAC-CE), or a radio resource control signal (RRC)) that indicates a power backoff for use of data symbols with reference to a defined reference symbol (e.g., a demodulation reference signal (DMRS) symbol associated with a data symbol). In some examples, when configured with a control signal, the UE may back off the transmit power of a set of data symbols to meet an average transmit power threshold configured by the network or based on UE capabilities.

[0006] Additionally or alternatively, if the network entity configures the symbol type in the downlink and the mean and / or variance of the distribution of the associated power backoff exceeds the power backoff threshold, the network may send an average power offset for use according to the given symbol type. In addition or in lieu of the average power offset, the network entity may also signal the variance distribution of the power offset across symbols. In some cases, the network entity may signal the power offset on a per-symbol basis. In some cases, the network entity may send a signal indicating a threshold allowed power offset for each symbol type so that the UE may not exceed the allowed power threshold in communications for the associated symbol type.

[0052] In some examples of wireless communications, a user equipment (UE) and a network entity may communicate based on unique word orthogonal frequency division multiplexing (UW-OFDM). In such examples, a given transmit time interval (TTI) may include a set of OFDM symbols, wherein each OFDM symbol may be associated with a fast Fourier transform (FFT) window including a guard interval (GI) portion and a data portion. The GI portion may be included in the FFT window at a segment of the FFT window that includes a set of zeros. In some examples, a set of zeros for a given symbol may be generated by combining a set of data tones carried by the symbol with a set of redundant tones, which may be a linear combination of the set of data tones. Additionally or alternatively, the data tones and the redundant tones may be combined so that a GI portion may be generated instead of a set of zeros.

[0053] Thus, the data tones and the redundant tones may be combined in the frequency domain so that the resulting FFT window includes samples in the GI portion of the OFDM symbol. However, in some cases, including a set of redundant tones for data transmission may increase the total power output associated with the data symbol. For example, the increase in power may be based on samples modulating the tones in the symbol in the frequency domain and may therefore vary from symbol to symbol. This increase in total power may result in a power offset between a first OFDM symbol carrying a reference signal (e.g., a demodulation reference signal (DMRS)) and a second OFDM symbol carrying data associated with the reference signal (e.g., on the same physical channel). In some cases, a wireless communication system may assume the same power output for transmission of DMRS symbols and data symbols. Therefore, decoding the reference signal and the data signal assuming the same power may be incorrect, error-prone, or both, resulting in poor communication performance (e.g., beam failures, increased retransmissions, poor throughput, etc.).

[0054] Therefore, the network entity and the UE may communicate additional signaling to identify the power offset between different symbol types for channel estimation. For example, the network entity may send a control signal (e.g., via downlink control information (DCI), a medium access control-control element (MAC-CE), or a radio resource control signal (RRC)) that indicates a power backoff for use of data symbols with reference to a defined reference symbol (e.g., a DMRS symbol associated with a data symbol). In some examples, when configured with the control signal, the UE may back off the transmit power of a set of data symbols to meet an average transmit power threshold configured by the network or according to UE capabilities.

[0055] Additionally or alternatively, if the network entity configures a symbol type in the downlink (e.g., physical downlink shared channel (PDSCH), position tracking reference signal (PTRS), channel state information reference signal (CSI-RS), etc.), and the average and / or variance of the associated power backoff for the symbol type exceeds a power backoff threshold, the network may send an average power offset for use according to a given symbol type. In addition or in lieu of the average power offset, the network entity may also signal a variance distribution of the power offset across symbols. In some cases, the network entity may signal a power offset on a per-symbol basis. In some cases, the network entity may send a signal indicating a threshold allowed power offset for each symbol type so that the UE may not exceed the allowed power threshold in communications for the associated symbol type.

[0056] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are further illustrated and described by and with reference to process flows. Aspects of the disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to signaling a power offset between reference tones and data tones.

[0057] Figure 1 An example of a wireless communication system 100 that supports signaling a power offset between a reference tone and a data tone according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0058] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, etc. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0059] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices that take different form factors or have different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with various types of devices, such as Figure 1 Communicate with other UEs 115 or network entities 105) as shown.

[0060] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0061] In some examples, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, the network entities 105 may communicate with each other directly (e.g., directly between each network entity 105) or indirectly (e.g., via the core network 130) via the backhaul communication link 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0062] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next-generation Node B, or a giga-Node B (any of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a home Node B, a home evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0063] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0064] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., RRC, service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by the other of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0065] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to the core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a host network entity 105 (e.g., a host base station 140). One or more host network entities 105 (e.g., IAB hosts) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB host. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0066] Where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support signaling a power offset between reference tones and data tones as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0067] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0068] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 shown.

[0069] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a set of RF spectrum resources having a defined physical layer structure to support the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between a device and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate," when referring to the network entity 105, may refer to any portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0070] The signal waveform transmitted via the carrier may be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that (e.g., in the transmission duration) a relatively high number of resource elements and a relatively high order modulation scheme may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers, beams), and the use of multiple spatial resources may increase the data rate or data integrity of the communication with the UE 115.

[0071] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0072] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, the time slot may be further divided into multiple micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0073] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0074] Physical channels may be multiplexed using carriers for communication according to various techniques. For example, physical control channels and physical data channels may be multiplexed via downlink carriers using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique for signaling. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0075] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0076] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). UE 115 can be designed to support ultra-reliable, low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency and ultra-reliable low-latency may be used interchangeably herein.

[0077] In some examples, the UE 115 may be configured to support communication directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0078] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to an external network (e.g., a serving gateway (S-GW)), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for one or more network operators. The IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0079] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 kilohertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range length is about one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0080] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to adopt license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entities 105 and UE 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations performed using unlicensed bands can be based on carrier aggregation configuration (e.g., LAA) in combination with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0081] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0082] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).

[0083] In some examples of the wireless communication system 100, the UE 115 and the network entity 105 can communicate according to the UW-OFDM scheme. In such examples, a given TTI may include a set of OFDM symbols, each of which may be associated with an FFT window including a GI portion and a data portion. The GI portion may be added in the FFT window at a section of the FFT window including a zero set. In some examples, a zero set for a given symbol may be generated by combining a set of data tones carried by the symbol with a set of redundant tones, which may be a linear combination of the set of data tones. Therefore, data tones and redundant tones may be combined in frequency space so that the resulting FFT window includes a zero set in the time domain. However, in some cases, including a set of redundant tones for data transmission may increase the total power output associated with the data symbol. This increase in total power may result in a power offset between a first OFDM symbol carrying a reference signal (e.g., DMRS) and a second OFDM symbol carrying data associated with a physical channel.

[0084] Therefore, the network entity 105 and the UE 115 may communicate additional signaling to clarify the power offset between different symbol types for channel estimation. For example, the network entity 105 may send a control signal indicating a power backoff for use of data symbols with reference to a defined reference symbol. Additionally or alternatively, if the network entity 105 configures the symbol type in the downlink and the distribution of the associated power backoff exceeds the power backoff threshold, the network may send an average power offset for use according to a given symbol type. In addition or in lieu of the average power offset, the network entity 105 may also signal the variance distribution of the power offset across symbols. In some cases, the network entity 105 may signal the power offset on a per-symbol basis. In some cases, the network entity 105 may send a signal indicating a threshold allowed power offset for each symbol type so that the UE 115 may not exceed the allowed power threshold in the communication of the associated symbol type.

[0085] Figure 2 An example of a wireless communication system 200 that supports signaling a power offset between a reference tone and a data tone according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 may implement one or more aspects of the wireless communication system 100. For example, the UE 115-a, the network entity 105-a, and the geographic coverage area 110-a may be as described in the reference Figure 1 Corresponding examples of UE 115, network entity 105, and geographic coverage area 110 are depicted. Although examples are discussed herein, any number of devices and device types may be used to implement the implementations described in this disclosure.

[0086] In some examples of the wireless communication system 200, the UE 115-a and the network entity 105-a can communicate according to the UW-OFDM scheme. UW-OFDM can be a GI-based waveform that can be used in addition to or instead of a cyclic prefix (CP)-based waveform (e.g., CP-OFDM). Therefore, the network entity 105-a can send a UW-OFDM scheme configuration 205 to the UE 115-a, which can establish the use of UW-OFDM symbols 210 for one or more TTIs. Figure 2 As shown, each UW-OFDM symbol 210 may be associated with an FFT window 225 including a GI 215 portion and a data 220 portion. In some examples, the GI 215 portion may be located within the FFT window 225, while the CP associated with the CP-OFDM may be located outside the FFT window 225. The GI 215 portion may be placed at the beginning or end of the FFT window 225. In some cases, including the GI 215 portion within the FFT window 225 may allow for flexible adaptation of the GI 215 type and length based on channel and multipath conditions while maintaining the associated UW-OFDM symbol 210 length. Additionally or alternatively, the use of the UW-OFDM scheme configuration 205 may enable the network entity 105-a or the UE 115-a to generate a UW (e.g., a known sequence) within the GI 215 portion. For example, the UW may be used as a reference signal or gap, and may be used for frequency or phase tracking, noise or interference estimation, inter-symbol interference (ISI), or a combination thereof.

[0087] In some cases, the GI 215 portion may be added to the FFT window 225 at a location in the FFT window 225 that includes a set of zeros (eg, a set N u , where N u For example, during subcarrier mapping in frequency space, network entity 105-a or UE 115-a may include a set of redundant tones that may be a linear combination of the data tones included in portion 220 of data. Thus, subcarriers carrying corresponding data tones and redundant tones may be modulated to generate a subcarrier of length N in the time domain. u Additionally or alternatively, the subcarriers carrying the corresponding data tones and redundant tones may be modulated to generate a length N in the time domain. u In an example where a ZT is generated, the resulting symbol may be an example of a ZT-OFDM symbol. In such an example, the network entity 105-a or the UE 115-a may modify the UW to the ZT of the ZT-OFDM symbol to produce a UW-OFDM symbol 210.

[0088] Based on the redundant tones being a function of the data tones, the redundant tones may vary from symbol to symbol. In some cases, a set of redundant tones including transmission for a UW-OFDM symbol 210 may increase the total power output of the transmission. This increase in total power may result in a power offset between a first UW-OFDM symbol 210 carrying a reference signal (e.g., DMRS) and a second UW-OFDM symbol 210 carrying data associated with a physical channel (e.g., a physical downlink shared channel (PDSCH)). Additionally or alternatively, the power offset between the DMRS tones and the data tones may vary for a given symbol type. For example, the first PDSCH symbol and the second PDSCH symbol may have different power offsets relative to the same reference symbol. However, in some cases, new radio (NR) technology may assume the same power output for the transmission of DMRS symbols and data symbols. Under this assumption, decoding the received communication may be incorrect, error-prone, or both, resulting in poor communication performance (e.g., increased retransmissions, poor throughput, etc.).

[0089] In order to maintain consistent transmit power between symbols, the power in the frequency domain may be reduced symbol by symbol. This may result in a power offset between a data tone in a data symbol (e.g., a PDSCH tone in a PDSCH symbol) and a reference tone in a reference symbol (e.g., a DMRS tone in a DMRS symbol). Therefore, the network entity 105-a and the UE 115-a may utilize additional signaling to clarify the power offset between different symbol types (e.g., the power offset between a reference symbol and a data symbol) for channel estimation. For example, the network entity 105-a may send a power offset indication message 230 (e.g., via DCI, MAC-CE, or RRC) indicating a power backoff for use of a data symbol with reference to a defined reference symbol (e.g., a DMRS symbol associated with a data symbol). For example, a power offset between two symbols (e.g., a PDSCH symbol and a DMRS symbol) may indicate an offset between the transmit powers of corresponding tones (e.g., tones at the same position in frequency) in the two symbols (e.g., between a data tone in a PDSCH symbol and a corresponding DMRS tone in a DMRS symbol). The power offset indication message 230 may be applicable to multiple symbol types (e.g., PDSCH, physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), PTRS, CSI-RS, etc.). In some examples, the UE 115-a may assume by default that there is no power backoff on the data tones relative to the reference tones, and thus if a power offset is not configured, the UE 115-a may absorb any remaining power offset during the channel estimation procedure.

[0090] Additionally or alternatively, if the power offset indication message 230 configures power backoff for uplink communications, the UE 115-a may identify a power backoff between transmitting reference signal tones and transmitting data tones to meet an average transmit power threshold configured by the network. For example, the UE 115-a may transmit a reference signal using a first transmit power and transmit a data signal associated with the reference signal using a second transmit power based on the indicated power offset. In such examples, the first transmit power and the second transmit power used may meet a maximum transmit power threshold. If power backoff is not configured for uplink communications, the UE 115-a may refrain from performing a backoff between reference signal tones and data tones during uplink transmissions, or may perform power backoff based on associated hardware capabilities at the UE 115-a.

[0091] In some examples, a given symbol type (e.g., PDSCH, PTRS, or CSI-RS in a downlink) may have an associated average power offset relative to an associated reference symbol. Thus, in situations where the distribution of power backoff varies significantly from symbol to symbol for a given symbol type (e.g., the difference in power offset between a first symbol of a first type and a second symbol of the first type is above a configured threshold), network entity 105-a may send a control message indicating the average power offset for the symbol type. In such examples, UE 115-a may use the average power offset indicated by network entity 105-a when receiving multiple symbols.

[0092] In addition to or in lieu of indicating an average power offset for a given symbol type, the network entity 105-a may send statistical information associated with the power offset across a set of UW-OFDM symbols 210. In some examples, the statistical information may indicate a variance of a distribution of power offsets across a set of UW-OFDM symbols 210. The indication of the statistical information may improve symbol-by-symbol channel estimation at the UE 115-a.

[0093] In some examples, the network entity 105-a or UE 115-a may signal a power offset for each symbol in a set of UW-OFDM symbols 210 (e.g., relative to a reference symbol). Thus, signaling may be initiated from the network entity 105-a or UE 115-a via a downlink or uplink, respectively. In some cases, the network entity 105-a or UE 115-a may send the signaling with each UW-OFDM symbol 210. For example, the network entity 105-a or UE 115-a may multiplex the signaling with the associated UW-OFDM symbol 210 (e.g., in frequency, in time, or in frequency and time). In some cases, the network entity 105-a or UE 115-a may send a signal once per time slot indicating the corresponding power offset for each UW-OFDM symbol 210 in the time slot. Additionally or alternatively, the network entity 105 - a or UE 115 - a may send signaling via a control channel (e.g., PDCCH or PUCCH) or as one or more reference tones on a shared channel (e.g., as part of a PDSCH symbol).

[0094] In some cases, the network entity 105-a may signal a control message to the UE 115-a indicating a power offset threshold associated with a symbol type of a reference symbol associated with a reference. For example, the network entity 105-a may indicate a power offset threshold for a PDSCH symbol so that the UE 115-a may assume that the power offset of the received PDSCH symbol (e.g., relative to the reference symbol) may be limited by the indicated power offset threshold. When receiving the PDSCH symbol, the UE 115-a may use this information to assist in the channel estimation and demodulation process. In some examples, the network entity 105-a and the UE 115-a may use the indicated power offset threshold in both uplink transmissions and downlink transmissions. For example, if a symbol-by-symbol power offset has not been configured, the network entity 105-a or the UE 115-a may use the indicated power offset threshold. Using the power offset threshold may limit errors in channel estimates associated with power offsets for upper and lower limits of a power offset distribution. If the power offset for a given UW-OFDM symbol 210 is above an indicated power offset threshold, the transmitting device (e.g., network entity 105-a or UE 115-a) may adjust the redundant tones used to generate the UW-OFDM symbol 210 to satisfy the indicated power offset threshold.

[0095] Based on the power offset indication message 230, the network entity 105-a and the UE 115-a may communicate a reference signal 235 and a data signal 240 according to the UW-OFDM scheme configuration 205. Thus, the data signal 240 may be communicated with a power offset relative to the reference signal 235 according to the techniques described herein.

[0096] In some examples of the wireless communication system 200, the network entity 105-a may configure the UE 115-a with a power offset indication message 230, wherein the power offset indication message 230 may request one or more indications from the UE 115-a. For example, the power offset indication message 230 may request statistical information about the power offset of the uplink symbol (e.g., the average transmit power per symbol or the variance of the transmit power per symbol). Additionally or alternatively, the power offset indication message 230 may request power offset information for a set of uplink symbols at the UE 115-a on a symbol-by-symbol basis. Thus, the UE 115-a may send one or more indications requested in the power offset indication message 230 to the network entity 105-a.

[0097] Figure 3 An example of a cumulative distribution function (CDF) 300 of a transmit power scheme that supports signaling a power offset between a reference tone and a data tone in accordance with one or more aspects of the present disclosure is illustrated. In some examples, the CDF 300 of the transmit power scheme can implement one or more aspects of the wireless communication system 100, the wireless communication system 200, or a combination thereof. For example, the UW-OFDM curve 305 can be for a reference tone in the time domain (e.g., after indicating power backoff) Figure 2

[0046] An example of a set of transmit powers for a set of UW-OFDM symbols 210. Although examples are discussed herein, any number of devices and device types may be used to implement the specific implementations described in this disclosure.

[0098] like Figure 3 As shown, the CDF 300 of the transmit power scheme may include a UW-OFDM curve 305 and a CP-OFDM curve 310. In some examples, the UW-OFDM curve 305 and the CP-OFDM curve 310 may be examples of normalized curves illustrating the distribution of transmit power for corresponding symbol types. For example, the UW-OFDM curve 305 may include a set of UW-OFDM symbols (e.g., associated with a physical channel), wherein the UW-OFDM curve 305 illustrates the distribution (e.g., likelihood) of transmit power for a given symbol type. Additionally or alternatively, the CP-OFDM curve 310 may include a set of CP symbols, wherein the CP-OFDM curve 305 illustrates the distribution (e.g., likelihood) of transmit power for a given CP symbol type.

[0099] like Figure 3 As shown, the UW-OFDM curve 305 and the CP-OFDM curve 310 can be centered around a transmit power of 0 dBm (e.g., the average transmit power can be 0 dBm). In some examples, the UW-OFDM curve 305 can have a steeper distribution curve centered around approximately 0 dBm. Thus, when transmitting one or more UW-OFDM symbols, a transmitting or receiving network device can operate according to the techniques described herein. For example, a wireless device (e.g., UE 115 or network entity 105) using UW-OFDM symbols can indicate an offset between the transmit powers of corresponding tones (e.g., tones at the same location in frequency) between a reference symbol (e.g., a DMRS symbol) and a data symbol (e.g., a PDSCH symbol). This document (including references to Figure 4 ) describes further discussion of tone-based power offset between two symbols.

[0100] Figure 4 An example of a CDF 400 for a power backoff scheme that supports signaling a power offset between a reference tone and a data tone according to one or more aspects of the present disclosure is illustrated. In some examples, the CDF 400 for a power backoff scheme can implement one or more aspects of the wireless communication system 100, the wireless communication system 200, or a combination thereof. For example, the PDSCH symbol curve 405 can be a PDSCH symbol (e.g., a reference tone) for a PDSCH symbol. Figure 2 210). In some examples, the set of offsets in transmit power may be used to maintain an average transmit power per UW-OFDM symbol in the time domain. Although examples are discussed herein, any number of devices and device types may be used to implement the specific implementations described in the present disclosure.

[0101] As described, power backoff of one or more tones of a UW-OFDM symbol may be used to generate a 0 dBm transmit power output. Figure 4 , the DMRS symbol curve 410 may include a set of sampled DMRS symbols, each sampled DMRS symbol including a DMRS tone (e.g., a quadrature phase shift keying (QPSK) constellation), wherein the DMRS tone in the DMRS symbol may have a fixed power backoff from 0 dBm (e.g., reference Figure 4Additionally or alternatively, the PDSCH symbol curve 405 may include a set of sampled PDSCH symbols (e.g., PDSCH symbols), each sampled PDSCH symbol including a set of data tones, wherein the UW-OFDM symbol power backoff may vary on a per-symbol basis. For example, the PDSCH symbols included in the PDSCH symbol curve 405 may be associated with an average power offset from 0 dBm (e.g., -2.66 dBm) and an associated 99% power offset tile range (e.g., -2.85 dBm to -2.33 dBm) from 0 dBm. Thus, there may be an average power offset and a variable power offset between a DMRS symbol and a given PDSCH symbol.

[0102] According to the described techniques, a transmitting wireless device (e.g., UE 115 or network entity 105) may indicate a power offset (such as a reference Figure 2 In some examples, the power offset message may indicate an average power offset for a PDSCH symbol type with reference to the DMRS symbol curve 410. Additionally or alternatively, the power offset message may indicate a variable power offset (e.g., a power offset range for a PDSCH symbol type with reference to the DMRS curve). Thus, a power offset may be used so that each UW-OFDM symbol may be transmitted with a transmit power of 0 dBm.

[0103] Figure 5 An example of a power backoff operation 500 that supports signaling a power offset between a reference tone and a data tone in accordance with one or more aspects of the present disclosure is illustrated. In some examples, the power backoff operation 500 can implement one or more aspects of the wireless communication system 100, the wireless communication system 200, or a combination thereof. For example, the DMRS symbol 525, the PDSCH symbol 530-a, and the PDSCH symbol 530-b can be a reference tone. Figure 2 2. Although examples are discussed herein, any number of devices and device types may be used to implement the specific implementations described in this disclosure.

[0104] In some examples, a wireless device (e.g., network entity 105 or UE 115) may transmit one or more UW-OFDM symbols having an associated average tone power 510 for a given tone in a set of UW-OFDM symbols. Thus, the wireless device may perform power backoff 505 on a set of UW-OFDM symbols (e.g., DMRS symbol 525, PDSCH symbol 530-a, and PDSCH symbol 530-b) such that each UW-OFDM symbol may have the same transmit power. For example, each UW-OFDM symbol may include a set of data tones 515 and a set of redundant tones 520, where the redundant tones 520 may be a function of the data tones 515. Reference Figure 5 , DMRS symbol 525 may include data tone 515-a and redundant tone 520-a, PDSCH symbol 530-a may include data tone 515-b and redundant tone 520-b, and PDSCH symbol 530-b may include data tone 515-c and redundant tone 520-c.

[0105] As reference Figure 4 As described, each DMRS symbol 525 may have the same power offset relative to 0 dBm, while the PDSCH symbols 530-a and 530-b may have power offsets that vary per symbol based on their corresponding data tones 515 and redundant tones 520. Thus, the wireless device may determine a power offset 540 for each PDSCH symbol 530 relative to the DMRS symbol 525. For example, the DMRS symbol 525 may have a reference power 535 associated with the data tone 515-a, which may be consistent across multiple DMRS symbols 525. Thus, the data tone 515-b of the PDSCH symbol 530-a may have a power offset 540-a relative to the reference power 535. Additionally or alternatively, the data tone 515-c of the PDSCH symbol 530-b may have a power offset 540-b related to the reference power 535. In some examples, each power offset 540 may indicate an offset between the transmit power of a corresponding tone (eg, a tone that is co-located in the frequency domain) between a DMRS symbol 525 and a given PDSCH symbol 530 .

[0106] Therefore, the wireless device may send a power offset message indicating a power backoff for use of the reference DMRS symbol 525 for the PDSCH symbol 530-a and the PDSCH symbol 530-b. In some cases, the power offset message may be a reference DMRS symbol 525. Figure 2 An example of a power offset indication message 230 is shown.

[0107] Figure 6An example of a process flow 600 for supporting signaling a power offset between a reference tone and a data tone in accordance with one or more aspects of the present disclosure is illustrated. In some examples, the process flow 600 may implement aspects of the wireless communication system 100, the wireless communication system 200, the CDF of the transmit power scheme 300, the CDF of the power backoff scheme 400, the power backoff operation 500, or a combination thereof. The process flow 600 includes a UE 115-b and a network entity 105-b, which may be a reference tone. Figure 1 and Figure 2 105 and corresponding examples of UE 115 and network entity 105 described. The following alternative examples may be implemented, in which some of the steps are performed in a different order than described or not performed at all. In some cases, the steps may include additional features not mentioned below, or other steps may be added. In addition, although process flow 600 shows the process between a single UE 115 and a single network entity 105, it should be understood that these processes may occur between any number of network devices and network device types.

[0108] At 605, UE 115-b may establish a wireless connection configured using a UW-OFDM scheme with network entity 105-b. For example, the UW-OFDM scheme configuration may indicate a set of symbols per TTI for OFDM communication, wherein each symbol in the set of symbols corresponds to an FFT window and includes a GI portion and a data portion within the FFT window.

[0109] At 610, UE 115-b may receive an indication of a power offset used in accordance with a UW-OFDM scheme. For example, UE 115-b may receive a control message indicating at least one parameter associated with a power offset between a data signal of a set of symbols and a reference signal associated with the data signal of the set of symbols.

[0110] At 615 , the UE 115 - b may communicate data signals and reference signals with the network entity 105 - b using the set of symbols in accordance with the indicated power offset.

[0111] Figure 7 An example of a process flow 700 for supporting signaling a power offset between a reference tone and a data tone in accordance with one or more aspects of the present disclosure is illustrated. In some examples, the process flow 700 can implement aspects of the wireless communication system 100, the wireless communication system 200, the CDF of the transmit power scheme 300, the CDF of the power backoff scheme 400, the power backoff operation 500, or a combination thereof. The process flow 700 includes a UE 115-c and a network entity 105-c, which can be a reference Figure 1 and Figure 2105 and corresponding examples of UE 115 and network entity 105 described. The following alternative examples may be implemented, in which some of the steps are performed in a different order than described or not performed at all. In some cases, the steps may include additional features not mentioned below, or other steps may be added. In addition, although process flow 700 shows a process between a single UE 115 and a single network entity 105, it should be understood that these processes may occur between any number of network devices and network device types.

[0112] At 705, the UE 115-c may establish a wireless connection configured using a UW-OFDM scheme with the network entity 105-c. For example, the UW-OFDM scheme configuration may indicate a set of symbols per TTI for OFDM communication, wherein each symbol in the set of symbols corresponds to an FFT window and includes a GI portion and a data portion within the FFT window.

[0113] At 710, UE 115-c may receive an indication of a power offset used in accordance with a UW-OFDM scheme. For example, UE 115-c may receive a control message indicating at least one parameter associated with a power offset between a data signal of a symbol set and a reference signal of the symbol set associated with the data signal. In some examples, the data signal may include a data tone in a data symbol within the symbol set, and the reference signal may include a reference tone in a reference symbol within the symbol set, the reference symbol being associated with the data symbol. In some examples, the control message may include an indication of whether UE 115-c is to use a power offset between a data signal and a reference signal associated with the data signal. In some examples, the control message may be a DCI, a MAC-CE, an RRC, or a combination thereof.

[0114] In some examples, techniques associated with power offsets may be applicable to both uplink and downlink communications. For example, if a power offset indication is associated with a downlink channel (e.g., PDSCH or PDCCH), the UE 115-c may use the power offset indication for symbol reception in the downlink. Additionally or alternatively, if a power offset indication is associated with an uplink channel (e.g., PUSCH or PUCCH), the UE 115-c may use the power offset indication for symbol transmission in the uplink. In some examples, the power offset indication may also be applied to multiple channels or symbol types. Therefore, the power offset indication may be used for both UE 115-c transmission and reception behavior.

[0115] In some examples, UE 115-c can receive a second control message indicating at least one parameter associated with a second power offset, the second power offset being associated with a symbol type including a data signal, the second power offset being between the data signal of the symbol type and a reference signal associated with the data signal. Thus, UE 115-c can receive the data signal and the reference signal from network entity 105-c based on the second indicated power offset.

[0116] In some examples, UE 115-c can receive a second control message indicating an average power offset and statistical information associated with the power offset across a set of symbols over a fixed duration of the wireless connection. Thus, UE 115-c can receive data signals and reference signals based on the average power offset and the statistical information.

[0117] In some examples, UE 115-c may receive a set of control messages indicating respective sets of power offsets, each power offset being associated with a different symbol type in a set of symbol types. In such examples, the data signal may be a first symbol type in the set of symbol types, and the power offset may be a first power offset in the set of power offsets that may be associated with the first symbol type. Additionally or alternatively, the reference signal may be a DMRS, and the set of symbol types may include one or more of a signal for a PDSCH, a signal for a PDCCH, a signal for a PUSCH, a signal for a PUCCH, a positioning reference signal (PRS), or a CSI-RS.

[0118] At 715 , the UE 115 - c may receive one or more control signals indicating a power offset of a data signal of a symbol in a set of symbols relative to an associated reference signal for a TTI.

[0119] In some examples, UE 115-c may receive, for each symbol in the set of symbols, a control signal in one or more control signals indicating an associated power offset for the symbol. In such examples, each control signal may include a reference signal multiplexed in frequency or time with the data signal on a shared channel. Additionally or alternatively, each control signal may be multiplexed in frequency or time with the data signal on a shared channel.

[0120] In some examples, UE 115-c may receive a control signal indicating a power offset applicable to a set of symbols for a TTI.

[0121] At 720, the UE 115-c may receive a second control message indicating a power offset threshold associated with a symbol type including a data signal. In such an example, the data signal and the reference signal may be communicated using a set of symbols according to a power offset based on the power offset satisfying the power offset threshold.

[0122] At 725, the UE 115-c may communicate the data signal and the reference signal with the network entity 105-c using the set of symbols according to the indicated power offset. For example, the UE 115-c may transmit the reference signal using a first transmit power backoff and transmit the data signal using a second transmit power backoff that may be based on the indicated power offset, wherein the first transmit power and the second transmit power may satisfy a maximum transmit power threshold. By using the first transmit power backoff and the second transmit power backoff for the respective reference signal and the data signal, the network entity 105-c and the UE 115-c may communicate the reference signal and the data signal using the same transmit power.
