[0002] This patent application claims priority to U.S. patent application No. 17 / 957,216, entitled “TECHNIQUES FOR REPORTING FREQUENCY CORRECTIONS,” filed by LANDIS et al. on September 30, 2022, which is assigned to the assignee of this application and is expressly incorporated herein by reference in its entirety. Technical Field

[0003] The following relates to wireless communications, including techniques for reporting frequency corrections. 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).

[0005] A wireless multiple access communication system may include one or more base stations, each of which supports wireless communication for communication devices, which may be referred to as user equipment (UE). In some wireless communication systems, a network entity (such as one or more components of a base station) may perform channel estimation on a channel. Summary of the invention

[0006] The described technology relates to improved methods, systems, devices and apparatuses that support technology for reporting frequency corrections. For example, the described technology may enable a network entity to perform channel estimation on a channel. For example, a network entity may use the technology described herein to perform channel estimation on a communication channel that undergoes flat fading, thereby improving the performance of the flat channel, improving the quality of communication and reducing latency. For example, the network entity may send a request to a user equipment (UE) to cause the UE to report one or more frequency corrections. The UE may monitor a set of one or more reference signals associated with performing the one or more frequency corrections at the UE. The UE may send the report indicating the one or more frequency corrections to the network entity according to one or more reporting parameters. In some examples, the network entity may receive the report via a channel that undergoes flat fading. In such examples, the network entity may perform channel estimation on the flat channel based on the reported frequency correction, thereby enabling the network entity to improve the accuracy of channel estimation in a channel that undergoes flat fading.

[0036] In some wireless communication systems, a network entity may communicate with a user equipment (UE) via one or more channels. In such systems, the network entity may perform channel estimation based on uplink signaling received from the UE, and the UE may perform channel estimation based on downlink signaling received from the network entity. In some cases, the network entity may receive uplink signaling from the UE in a channel that undergoes flat fading. Since the frequency allocation for the channel is less than the coherence bandwidth of the channel (e.g., a measurement of the frequency range within which the channel is constant or flat), the channel may experience flat fading. In such cases, each frequency component (e.g., of a signal) sent in the channel may experience the same amplitude and phase fading. Additionally, the channel may experience flat fading in line-of-sight (LOS) communications (e.g., where the coherence bandwidth may be infinite, making the frequency allocation less than the coherence bandwidth).

[0037] In the case of flat fading, the network entity may not be able to accurately perform channel estimation on the received uplink signaling. For example, the network entity may receive uplink signaling including multiple demodulation reference signals (DMRS). As part of the channel estimation, the network entity may determine whether the frequency component of the channel is experiencing Doppler spread or Doppler shift based on measuring the correlation of two or more DMRS received in different symbols in the uplink signaling. However, if the network entity receives uplink signaling via a flat channel (e.g., a channel experiencing flat fading), the network entity may not be able to determine whether the flat channel is experiencing Doppler shift or Doppler spread, thereby increasing the error when performing channel estimation. The increased error in channel estimation may result in increased latency, poor channel quality, and reduced user experience.

[0038] The techniques described herein may enable a network entity to improve the accuracy with which channel estimation is performed. For example, a UE may receive a request from a network entity to report a frequency correction (e.g., frequency error correction) performed during channel estimation. The UE may monitor one or more reference signals (e.g., DMRS, tracking reference signal (TRS) or both) in downlink signaling from the network entity. In order to receive one or more reference signals from the network entity, the UE may perform a frequency correction (e.g., adjust one or more timing parameters or frequency parameters at the UE). Based on the time and frequency correction for receiving the reference signal, the UE may adjust one or more frequency or time parameters for sending uplink signaling. In addition to sending uplink signaling, the UE may also send a report indicating the frequency correction to the network entity. In some cases, the network entity may receive uplink signaling via a flat channel. In such cases, the network entity may use the received frequency correction to perform channel estimation. Therefore, based on the received frequency correction, the network entity may estimate a flat channel, thereby reducing channel estimation errors, reducing latency, and improving channel quality.

[0039] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are illustrated in the context of a process flow. Aspects of the disclosure are further illustrated by apparatus diagrams, system diagrams, and flow diagrams relating to techniques for reporting frequency corrections, and are described with reference to these diagrams.

[0040] Figure 1An example of a wireless communication system 100 supporting techniques for reporting frequency corrections 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.

[0041] 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, among other nomenclature. 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) within 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 within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0042] 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 in different forms or with 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 1 105 or other UEs 115 or network entities 105) as shown.

[0043] 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.

[0044] 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 communication 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 via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication links 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication links 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, the midhaul communication links 162, or the fronthaul communication links 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 .

[0045] 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 gigabit 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, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0046] 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)).

[0047] 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., radio resource control (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 different ones 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.

[0048] 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 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 controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) 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 coupled IAB donor's DU 165. 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.

[0049] 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 the techniques for reporting frequency correction 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).

[0050] 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.

[0051] 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, or relay base stations, etc. Figure 1 shown.

[0052] 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 physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may consist of 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 to have 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 these devices and any part (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 part of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0053] The signal waveform transmitted via the carrier may include 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 employing 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 a relatively higher amount of resource elements (e.g., in the transmission duration) and a relatively higher order of the modulation scheme may correspond to a relatively higher communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0054] 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. 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).

[0055] 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 a certain number of 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 a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slots may be further divided into mini-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.

[0056] 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 amount 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 a burst of a shortened TTI (sTTI)).

[0057] Carriers may be used to multiplex physical channels for communication according to various techniques. Physical control channels and physical data channels may be multiplexed via downlink carriers for signaling, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. 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 UE115 may monitor or search a control region to obtain 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 multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0058] 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 respective coverage areas 110 using the same or different radio access technologies.

[0059] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable or 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.

[0060] In some examples, a UE 115 may be configured to support communication directly with other UEs 115 via 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 by the network entity 105 (e.g., scheduled by the network entity). In some examples, one or more UEs 115 in such a group may be outside 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.

[0061] 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 (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of 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 via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0062] 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 gigahertz (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 wavelengths range from about one decimeter to one meter in length. 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) than communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0063] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed bands (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating using unlicensed RF spectrum bands, devices such as the network entity 105 and the UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0064] 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) communication, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which 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 antenna ports of multiple rows and columns 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.

[0065] 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 these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0066] In some examples of the wireless communication system 100, the network entity 105 may communicate with the UE 115 via one or more channels. In such cases, the network entity 105 may communicate with the UE 115 via a channel that may experience flat fading (e.g., a flat channel or a nearly flat channel), such that signals sent via the flat channel may experience the same amplitude and phase fading. A flat channel may occur due to a frequency allocation of the channel being less than the coherence bandwidth of the channel. Additionally, a flat channel may be due to LOS communication (where the coherence bandwidth is infinite, such that the frequency allocation is less than the coherence bandwidth).

[0067] In some cases, the network entity 105 may estimate channel statistics, such as delay spread, Doppler spread, and signal-to-noise ratio (SNR), based on one or more signals (e.g., DMRS or TRS) sent from the UE 115. For example, the network entity 105 may estimate the Doppler spread of the channel based on a measured empirical correlation between two or more DMRSs in different orthogonal frequency division multiplexing (OFDM) symbols of an uplink channel (e.g., a physical uplink shared channel (PUSCH)). However, if the network entity 105 receives the DMRS via a flat channel, the network entity 105 (e.g., due to lack of statistics between the DMRSs) may not be able to correctly estimate the Doppler spread. For example, if the amplitude and phase of the frequency component vary in the channel (e.g., a non-flat channel), the network entity 105 may be able to estimate the Doppler spread due to the difference in the DMRS received in each OFDM symbol. However, in the case of a flat channel, the network entity 105 may not be able to estimate the Doppler spread due to similar amplitude and phase fading on the channel. In addition, in some cases of a flat channel, the phase of the DMRS may vary between OFDM symbols. In such cases, the network entity 105 or UE 115 may not be able to distinguish whether the phase difference between the DMRS is due to the flat fading of the channel or due to the Doppler shift of the LOS channel. Therefore, when communicating on a flat channel, the network entity 105 may not be able to determine whether a Doppler shift or Doppler spread has occurred in the channel, thereby introducing errors in channel estimation, increasing latency, and reducing user experience.

[0068] In order for the network entity 105 to determine the cause of the flat channel and improve the accuracy of the channel estimation, the network entity 105 may request a frequency correction report from the UE 115 to assist in the channel estimation of the flat channel. For example, the UE 115 may receive a request from the network entity 105 to report the frequency correction implemented at the UE 115. For example, the UE 115 may monitor one or more DMRS, TRS, or both. In order to receive the DMRS or TRS, the UE 115 may perform a frequency correction (e.g., adjust one or more timing parameters and frequency parameters at the UE 115). The UE 115 may perform the frequency correction before sending the uplink signaling to the network entity 105. In some examples, the uplink signaling may be based on the frequency correction performed to receive the DMRS or TRS. Additionally, the UE 115 may send a report indicating the frequency correction to the network entity 105. In some examples, the network entity 105 may receive the uplink signaling via a flat channel. In such cases, the network entity 105 may use the received frequency correction to perform channel estimation for a flat channel, thereby improving performance when a flat channel is encountered (e.g., when the frequency allocation of the channel is less than the coherence bandwidth of the channel), improving channel estimation accuracy, and improving user experience.

[0069] Figure 2 An example of a wireless communication system 200 that supports techniques for reporting frequency correction according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may be implemented as shown in FIG. Figure 1 Various aspects of the wireless communication system 100 described herein may be implemented by various aspects of the wireless communication system. For example, the wireless communication system 200 may include a UE 115-a and a network entity 105-a, which may be as described herein with reference to Figure 1 Depicted are examples of UE 115 and network entity 105 . UE 115 - a and network entity 105 - a may operate within a coverage area 110 - a , which may be an example of coverage area 110 .

[0070] In some cases, the UE 115-a may monitor a reference signal 215 from the network entity 105-a. The reference signal 215 may include a DMRS, a TRS, or a combination thereof. In such cases, in order to successfully decode the reference signal 215, the UE 115 may perform one or more frequency corrections (e.g., by adjusting a crystal or an internal clock of a receive chain at the UE 115-a). For example, the UE 115-a may continuously estimate a timing error and a frequency error of a channel between the UE 115-a and the network entity 105-a based on the reference signal 215 (e.g., based on decoding TRS and DMRS received in a physical downlink shared channel (PDSCH)). The frequency error of the channel may be caused by channel conditions, while the timing error may be caused by an error in an oscillator (XO) crystal (e.g., an internal clock) of the UE 115-a. In some cases, Doppler spread or Doppler shift may result in frequency changes caused by channel conditions. A Doppler shift may be a frequency change of a channel from a single source (e.g., a single reflector), which results in a slow change in the frequency trend of the channel. A Doppler spread may be a combination of frequency changes of a channel due to one or more Doppler shifts with multiple reflectors (e.g., objects located on the communication path between the network entity 105-a and the UE 115-a) having different speeds. In the case of a Doppler spread, the frequency may change relatively quickly in time even if the physical speed of the UE 115-a remains unchanged. For example, the number of increased reflectors in the communication channel between the UE 115-a and the network entity 105-a may result in multiple Doppler shifts in the channel (e.g., all of which have different speeds). Therefore, a Doppler spread of a channel may refer to one or more Doppler shifts occurring in a channel, all of which have different rates of change.

[0071] In some cases, the network entity 105-a and the UE 115-a may communicate via a flat channel. For example, the UE 115-a may send one or more uplink signals via a channel, where the frequency allocation for the channel is less than the coherence bandwidth of the channel. In such examples, the network entity 105-a may receive the one or more uplink signals via the flat channel (e.g., the network entity encounters a flat channel). The network entity 105-a may attempt to empirically estimate the time correlation (e.g., Doppler spread) of the channel over two or more DMRSs of a channel (e.g., a physical uplink shared channel) using Formula 1:

[0072]

[0073] Where k represents the time index offset between DMRSs, p i represents the sample from the first DMRS in resource element i, and p i+k represents the samples from the second DMRS at resource element i.

[0074] However, in the case of flat fading (e.g., when the network entity 105-a encounters a flat channel), there may be no statistics due to the variation of the DMRS in the flat channel, and thus the network entity 105-a may not be able to accurately estimate the time correlation. For example, in a flat channel, the amplitude and phase fading of the signal across different frequency components may be similar. Subsequently, the time correlation between DMRS across multiple symbols may be similar. Therefore, in the case of a flat channel, the estimation using Formula 1 may result in a value of "1", which may not represent the actual Doppler spread of the channel. Without accurate time correlation estimation, the network entity 105-a may not be able to accurately perform channel estimation, resulting in reduced channel quality, increased latency, and a poor user experience.

[0075] In some specific implementations of the wireless communication system 200, in order to improve the accuracy of channel estimation for a flat channel, the network entity 105-a may request a report of frequency correction from the UE 115-a. For example, the UE 115-a may send a UE capability message 205, which indicates that the UE 115-a is capable of sending an indication of frequency correction to the network entity 105-a. The UE capability message 205 may be included in uplink control information (UCI), a MAC control element (MAC-CE), an RRC message, or a combination thereof. Based on receiving the UE capability message 205, the network entity 105-a may send a request message 210, which requests the transmission of a frequency correction report 220. The request message 210 may be included in downlink control information (DCI), an RRC message, or a combination thereof. In some examples, the request message 210 may include one or more reporting parameters associated with reporting frequency correction.

[0076] For example, the one or more reporting parameters may include a periodicity with which the UE 115-a will report a frequency correction (e.g., send a frequency correction report 220), a trigger for sending a frequency correction report 220 (e.g., a non-periodic frequency correction report), or both. In some implementations, the reporting parameters may include a threshold configured by the network entity 105-a, and if the frequency correction satisfies the threshold, the UE 115-a may send the frequency correction report 220. Additionally, the network entity 105-a may indicate to the UE 115-a which DMRS or TRS to use when reporting the frequency correction (e.g., the last TRS or DMRS). For example, the network entity 105-a may indicate that the UE 115-a is to report a frequency correction associated with decoding the last (most recent) DMRS or TRS.

[0077] The network entity 105-a may send a reference signal 215-a to the UE 115-a via a downlink channel (e.g., a PDSCH), which may include one or more DMRSs, one or more TRSs, or both. The UE 115-a may monitor the reference signal 215-a and decode the reference signal 215-a using one or more frequency corrections. In response to the request message 210, the UE 115-a may send uplink signaling to the network entity 105-a based on the one or more frequency corrections (e.g., by applying the same or similar frequency correction to decode the DMRS for transmission at the UE 115-a). In addition to sending the uplink signaling, the UE 115-a may send a frequency correction report 220-a to the network entity 105-a via the PUSCH, which indicates one or more frequency corrections. The frequency correction report 220 may be included in a UCI, a MAC-CE, an RRC message (as a payload of the PUSCH), or a combination thereof. The network entity 105 - a may use the frequency correction received in the frequency correction report 220 - a to perform channel estimation.

[0078] In some examples, the network entity 105-a may compare the frequency correction received in the frequency correction report 220-a with the frequency correction performed by the network entity 105-a. If the correlation between the frequency correction of the UE 115-a and the frequency correction of the network entity 105-a is low, the network entity 105-a may determine that the channel is experiencing flat fading due to Doppler spread (e.g., the frequency of the channel changes faster at the UE 115-a), and may assume that the time correlation between the time at the UE 115-a and the time at the network entity 105-a is low, thereby performing channel estimation. Alternatively, if the correlation between the frequency correction of the UE 115-a and the frequency correction of the network entity 105-a is high, the network entity 105-a may determine that the channel is experiencing flat fading due to Doppler shift (e.g., the frequency of the channel changes slower at the UE 115-a), and may assume that the time correlation between the UE 115-a and the network entity 105-a is high, thereby performing channel estimation.

[0079] In addition, UE 115-a may send frequency correction report 220-b based on one or more operating parameters (e.g., operating parameters indicated by network entity 105-a). For example, UE 115-a may receive reference signal 215-b and decode reference signal 215-b using one or more frequency corrections. In such examples, UE 115-a may send frequency correction report 220-b to network entity 105-a. In some examples, one or more operating parameters may indicate the periodicity with which UE 115-a will send frequency correction report 220-b. In some examples, one or more operating parameters may indicate a trigger for UE 115-a to send frequency correction report. In such examples, the trigger may be based on UE 115-a receiving reference signal 215-b or one of reference signals 215-b. For example, based on receiving reference signal 215-b, UE 115-a may decode reference signal 215-b using frequency corrections and send frequency correction report 220-b to network entity 105-a. In some examples, UE 115-a may receive reference signal 215-b and use frequency correction to decode reference signal 215-b. In such examples, UE 115-a may determine that the frequency correction used to decode reference signal 215-b satisfies an indicated frequency threshold. UE 115-b may send a frequency correction report 220-b based on the frequency correction satisfying the frequency threshold. Network entity 105-a may receive frequency correction report 220-b via a PUSCH experiencing flat fading. Network entity 105-a may use the indicated frequency correction to perform channel estimation, thereby improving communication quality in a channel experiencing flat fading.

[0080] Figure 3An example of a process flow 300 supporting techniques for reporting frequency correction according to one or more aspects of the present disclosure is illustrated. The process flow 300 may implement reference Figure 1 and Figure 2 Aspects of the wireless communication system 100 and the wireless communication system 200 described herein may be implemented thereby. For example, the process flow 300 may include the UE 115-b and the network entity 105-b, which may be as described herein with reference to Figure 1 and Figure 2 Examples of corresponding devices described. In the following description of the process flow 300, the operations may be performed in an order different from the order shown. Certain operations may also be excluded from the process flow 300, or other operations may be added to the process flow 300. In addition, although some operations or signaling are shown as occurring at different times for discussion purposes, these operations may actually occur simultaneously.

[0081] At 305, UE 115-b may optionally send an indication of UE capability to report one or more frequency corrections to network entity 105-b. This indication of UE capability may be as described herein with reference to Figure 2 An example of a UE capabilities message 205 is described.

[0082] At 310, UE 115-b may receive, and network entity 105-b may send, a request to report the one or more frequency corrections. The request may include an indication of one or more reporting parameters for the one or more frequency corrections. The one or more reporting parameters may indicate a periodicity for sending the report of the one or more frequency corrections. Additionally, the one or more reporting parameters may indicate a trigger for sending the report, wherein the trigger includes receiving one or more reference signals at UE 115-b. In some examples, the one or more reporting parameters may include a threshold value such that if the frequency correction at UE 115-b is greater than the indicated threshold value, UE 115-b may send a report of the one or more frequency corrections.

[0083] At 315, the network entity 105-b may send a set of one or more reference signals associated with performing the one or more frequency corrections. The set of one or more reference signals may include at least one of a DMRS, a TRS, or a combination thereof. At 320, the UE 115-b may monitor the set of one or more reference signals. For example, in order to monitor and decode the set of one or more reference signals, the UE 115-b may perform the one or more frequency corrections.

[0084] At 325, UE 115-b may send the report indicating the one or more frequency corrections to network entity 105-b based on the one or more reporting parameters. For example, UE 115-b may send the report based on the periodicity indicated in the reporting parameters (e.g., a periodic report). In some examples, UE 115-b may send the report based on receiving the one or more reference signals based on the trigger indicated in the one or more reporting parameters (e.g., a non-periodic report). In some examples, UE 115-b may determine that the one or more frequency corrections satisfy an indicated threshold, wherein the report is sent based on the one or more frequency corrections satisfying the indicated threshold.

[0085] At 330, the network entity 105-b may optionally perform channel estimation based on the report indicating the one or more frequency corrections. For example, the network entity 105-b may receive the report in a channel that experiences flat fading. In such an example, the network entity 105-b may determine whether Doppler shift or Doppler spread is affecting the channel and estimate the channel based on the one or more frequency corrections.

[0086] At 335, the network entity 105-b may optionally send a second set of one or more reference signals after sending the set of one or more reference signals. At 340, the UE 115-b may optionally monitor the second set of one or more reference signals and decode the second set of one or more reference signals using the second set of frequency error corrections.

[0087] At 345, the UE 115-b may optionally send a second report indicating the second set of frequency error corrections based on the one or more reporting parameters and the second set of one or more reference signals. At 350, the network entity 105-b may optionally perform channel estimation based on the report indicating the one or more frequency corrections and the second report indicating the second set of frequency error corrections.

[0088] Figure 4 A block diagram 400 of a device 405 supporting techniques for reporting frequency corrections according to one or more aspects of the present disclosure is illustrated. The device 405 may be an example of aspects of a UE 115 as described herein. The device 405 may include a receiver 410, a transmitter 415, and a communication manager 420. The device 405 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0089] Receiver 410 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to techniques for reporting frequency corrections). The information may be communicated to other components of device 405. Receiver 410 may utilize a single antenna or a set of multiple antennas.

[0090] Transmitter 415 may provide means for transmitting signals generated by other components of device 405. For example, transmitter 415 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to techniques for reporting frequency corrections). In some examples, transmitter 415 may be co-located with receiver 410 in a transceiver module. Transmitter 415 may utilize a single antenna or a set of multiple antennas.

[0091] The communication manager 420, the receiver 410, the transmitter 415, or various combinations thereof, or various components thereof may be examples of means for performing various aspects of the techniques for reporting frequency corrections as described herein. For example, the communication manager 420, the receiver 410, the transmitter 415, or various combinations thereof, or components thereof may support methods for performing one or more of the functions described herein.
