[0001] This application claims the benefit of Greek patent application No. 20230100578, filed on July 14, 2023, entitled “INDICATING USER EQUIPMENT (UE)PHASE CONTINUITY IN A WIRELESS COMMUNICATION SYSTEM”, the entire contents of which are expressly incorporated herein by reference. Technical Field

[0002] All aspects of this disclosure relate to wireless communication systems in general, and more specifically to indicating the phase continuity of user equipment (UE) in wireless communication systems. Background Technology

[0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, message sending and receiving, and broadcasting. These wireless networks can be multiple-access networks capable of supporting multiple users by sharing available network resources.

[0004] A wireless communication network may include several components. These components may include wireless communication devices, such as a base station (or node B) that can support communication between multiple user equipments (UEs). UEs may communicate with the base station via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the base station to the UE, and an uplink (or reverse link) refers to the communication link from the UE to the base station.

[0005] A base station can transmit data and control information to a UE on the downlink or receive data and control information from a UE on the uplink. On the downlink, transmissions from the base station may encounter interference from neighboring base stations or other radio frequency (RF) transmitters. On the uplink, transmissions from the UE may encounter interference from other UEs communicating with neighboring base stations or from other RF transmitters. This interference can degrade performance on both the downlink and uplink.

[0006] In some wireless communication systems, the UE and other devices can use sensors to sense data and perform operations. For example, a UE might correspond to a vehicle using sensors to estimate parameters (such as estimating vehicle speed). Furthermore, some wireless communication systems use Joint Communication and Radar Sensing (JCR) techniques to jointly perform communication operations (such as cellular communication operations) and radar sensing operations, which can simplify device operation, hardware, or other features compared to performing such operations separately. In some instances, jointly performing such operations can degrade device performance within the wireless communication system, such as by interrupting the UE's operating state to change from sensing operations to communication operations (or vice versa), which in some cases may affect the accuracy of one or both of the sensing or communication operations. Summary of the Invention

[0007] In one aspect of this disclosure, an apparatus for wireless communication by a user equipment (UE) includes a transmitter and a receiver. The transmitter is configured to transmit a message including an indication of maintaining phase continuity of a sensing reference signal (SRS) during a processing interval associated with joint sensing operation. The receiver is configured to receive control information associated with the indication.

[0008] In another aspect, a method of wireless communication performed by a UE includes transmitting a message that includes an indication to maintain the phase continuity of the SRS during a processing interval associated with joint sensing operation. The method also includes receiving control information associated with the indication.

[0009] In another aspect, an apparatus for wireless communication by a network node includes a receiver and a transmitter. The receiver is configured to receive a message including an indication to the UE to maintain phase continuity of SRS during a processing interval associated with joint sensing operation. The transmitter is configured to transmit control information associated with the indication.

[0010] In another aspect, a method for wireless communication performed by a network node includes receiving a message that includes an indication to the UE to maintain phase continuity of the SRS during a processing interval associated with joint sensing operation. The method also includes transmitting control information associated with the indication.

[0011] While some aspects and implementations may be described through examples in this application, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, aspects and / or the use of devices that can be implemented via integrated chip implementations and other non-modular component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not specifically point to use cases or applications, broad applicability of the described innovations is evident. The scope of implementations can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical contexts, devices incorporating the described aspects and features may also necessarily include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components (e.g., hardware components, including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.) for analog and digital purposes. The innovations described herein are intended to be implemented in a variety of devices, chip-level components, systems, distributed arrangements, end-user equipment, etc., with different sizes, shapes, and constructions.

[0021] The same reference numerals and names in the various figures indicate the same elements. Detailed Implementation

[0022] In some aspects, a user equipment (UE) can instruct one or more network nodes of its ability to maintain phase continuity associated with a sensing reference signal (SRS). For example, during a sensing operation (such as a sensing operation to estimate location, velocity, or acceleration), the UE can transmit an SRS pulse and can perform one or more additional operations, such as one or more cellular communication operations, between the transmissions of the SRS pulse. The UE can instruct itself to perform one or more of these additional operations while maintaining phase continuity of at least a threshold amount from one SRS pulse to another.

[0023] One or more network nodes may schedule, allocate, or configure resources for the UE based on an indication of phase continuity. As an illustrative example, if the UE indicates that it can (or cannot) receive downlink signals between SRS pulses, the resources may include (or may exclude) downlink resources for receiving one or more downlink signals between two or more SRS pulses. Other examples are also within the scope of this disclosure.

[0024] By instructing the UE's ability to maintain phase continuity associated with the SRS, the reliability of one or more operations at the UE can be improved. For example, because some sensing operations (such as certain speed sensing operations) may be relatively sensitive to the phase of the SRS, avoiding certain operations that might change or degrade the phase from one SRS pulse to another can improve the phase continuity between SRS pulses. Therefore, the accuracy of such sensing operations can be improved.

[0025] Alternatively or otherwise, improved accuracy can reduce or eliminate the need for certain circuitry that may be relatively expensive or complex to implement. For example, some operations performed between SRS pulses can use dedicated hardware or other circuitry, such as hardware or circuitry that facilitates beam-switching operations or operations based on sleep modes. By instructing the network node of the UE's ability to maintain phase, the network node can avoid allocating, configuring, or scheduling resources for such operations between SRS pulses. Therefore, the use of such hardware or circuitry can be reduced or eliminated, thereby lowering UE cost and complexity.

[0026] In various specific implementations, technologies and devices can be used in wireless communication networks such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) networks, Single Carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, fifth-generation (5G) or new radio (NR) networks (sometimes referred to as "5G NR" networks, systems, or devices), and other communication networks. As described herein, the terms "network" and "system" are used interchangeably.

[0027] For example, CDMA networks can implement radio technologies such as Universal Terrestrial Radio Access (UTRA) and CDMA2000. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers the IS-2000, IS-95, and IS-856 standards.

[0028] For example, TDMA networks can implement radio technologies such as the Global System for Mobile Communications (GSM). The 3rd Generation Partnership Project (3GPP) defines the standard for the GSM EDGE (Enhanced Data Rate GSM Evolution) Radio Access Network (RAN) (also known as GERAN). GERAN is the radio component of the network connecting GSM / EDGE base stations (e.g., Ater and Abis interfaces) and base station controllers (A interface, etc.). The radio access network represents a component of the GSM network through which telephone calls and packet data are routed from the Public Switched Telephone Network (PSTN) and the Internet to subscriber handsets (also known as user terminals or user equipment (UEs)) and from subscriber handsets to the PSTN and the Internet. A mobile phone operator's network may include one or more GERANs, which may be coupled with UTRAN in the case of UMTS / GSM networks. Additionally, the operator's network may also include one or more LTE networks, or one or more other networks. Different network types may use different radio access technologies (RATs) and RANs.

[0029] OFDMA networks can implement radio technologies such as Evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, and flash-OFDM. UTRA, E-UTRA, and GSM are part of the Universal Mobile Telecommunications System (UMTS). Specifically, Long Term Evolution (LTE) is a UMTS version using E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents provided by an organization called the 3rd Generation Partnership Project (3GPP), and cdma2000 is described in documents from an organization called 3rd Generation Partnership Project 2 (3GPP2). These various radio technologies and standards are known or under development. For example, 3GPP is a collaboration among telecommunications associations aimed at defining globally applicable third-generation (3G) mobile phone specifications. 3GPP LTE is a 3GPP initiative aimed at improving the UMTS mobile phone standard. 3GPP defines specifications for next-generation mobile networks, mobile systems, and mobile devices. This disclosure may refer to LTE, 4G, or 5G NR technologies to describe certain aspects; however, this description is not intended to be limited to a particular technology or application, and one or more aspects described with reference to one technology may be understood to be applicable to another technology. Additionally, one or more aspects of this disclosure may relate to shared access to radio spectrum between networks using different radio access technologies or radio air interfaces.

[0030] 5G networks are expected to have diverse deployments, diverse spectrum, and diverse services and devices that can be achieved using a unified OFDM-based air interface. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further enhancements to LTE and LTE-A are also being considered. 5G NR will be able to scale to (1) provide coverage to large-scale Internet of Things (IoT) with ultra-high density (e.g., about 1M nodes / km^2), ultra-low complexity (e.g., about 10 bits / second), ultra-low power consumption (e.g., about 10+ years of battery life), and deep coverage to reach challenging locations; (2) include mission-critical controls with strong security to protect sensitive personal, financial or classified information, ultra-high reliability (e.g., about 99.9999% reliability), ultra-low latency (e.g., about 1 millisecond (ms)), and users with wide range of mobility or lack of mobility; and (3) provide coverage with enhanced mobile broadband (including extremely high capacity (e.g., about 10Tbps / km^2), extremely high data rates (e.g., multi-Gbps rates, 100+Mbps user experience rates)) and with deep awareness with advanced discovery and optimization.

[0031] Devices, networks, and systems can be configured to communicate via one or more portions of the electromagnetic spectrum. The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency or wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the “sub-6GHz” band. A similar naming issue sometimes arises for FR2, which in documents and articles is often (interchangeably) referred to as the “millimeter wave” (mmWave) band, although this is different from the extremely high frequency (EHF) band (30GHz to 300GHz) designated as “mmWave” by the International Telecommunication Union (ITU).

[0032] Considering the above aspects, unless otherwise specifically stated, it should be understood that when the term "below 6 GHz" is used herein, it can broadly refer to frequencies that are less than 6 GHz, within FR1, or may include intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that when the term "mmWave" is used herein, it can broadly refer to frequencies that may include intermediate frequency band frequencies, within FR2, or within the EHF band.

[0033] 5G NR devices, networks, and systems can be implemented using optimized OFDM-based waveform characteristics. These characteristics may include scalable parameter sets and transmission time intervals (TTI); a common, flexible framework for efficiently multiplexing services and characteristics using dynamic, low-latency Time Division Duplex (TDD) or Frequency Division Duplex (FDD) designs; and advanced radio technologies such as massive MIMO, robust mmWave transmission, advanced channel decoding, and device-centric mobility. The scalability of parameter sets in 5G NR efficiently addresses the operation of diverse services across different spectrums and deployments through subcarrier spacing scaling. For example, in various outdoor and macro coverage deployments implementing FDD or TDD below 3 GHz, subcarrier spacing may occur at 15 kHz, such as bandwidths exceeding 1 MHz, 5 MHz, 10 MHz, 20 MHz, etc. For other various outdoor and small cell coverage deployments with TDD above 3 GHz, subcarrier spacing may occur at 30 kHz over an 80 MHz / 100 MHz bandwidth. For various other indoor broadband implementations using TDD on the unlicensed portion of the 5 GHz band, subcarrier spacing may occur at 60 kHz over a 160 MHz bandwidth. Finally, for various deployments transmitting via mmWave components under 28 GHz TDD, subcarrier spacing may occur at 120 kHz over a 500 MHz bandwidth.

[0034] 5G NR's scalable parameter set facilitates scalable TTIs for diverse latency and Quality of Service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectrum efficiency. Efficient multiplexing of long and short TTIs allows transmission to begin at symbol boundaries. 5G NR also anticipates self-contained integrated subframe designs, where uplink or downlink scheduling information, data, and acknowledgments reside in the same subframe. Self-contained integrated subframes support communication in unlicensed or contention-based shared spectrum, with adaptive uplink or downlink that can be flexibly configured on a per-cell basis to dynamically switch between uplink and downlink to meet current service demands.

[0035] For clarity, certain aspects of the apparatus and technology may be described below with reference to example 5G NR implementations or in a 5G-centric manner, and 5G terminology may be used as illustrative examples in the sections described below; however, this description is not intended to be limited to 5G applications.

[0036] Furthermore, it should be understood that, in operation, wireless communication networks adapted according to the concepts herein may operate using any combination of licensed or unlicensed spectrum, depending on load and availability. Therefore, it will be apparent to those skilled in the art that the systems, apparatuses, and methods described herein can be applied to other communication systems and applications besides the specific examples provided.

[0037] While aspects and implementations are described herein by way of example, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, implementations or uses may be achieved via integrated chip implementations or other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail or purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not specifically point to use cases or applications, broad applicability of the described innovations is evident. Implementations can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the described aspects. In some practical contexts, devices incorporating the described aspects and features may also necessarily include additional components and features for implementing and practicing the claimed and described aspects. The innovations described herein are expected to be implemented in a wide variety of specific implementations of different sizes, shapes and constructions, including both large and small devices, chip-level components, multi-component systems (e.g., radio frequency (RF) chains, communication interfaces, processors), distributed deployments, end-user equipment, etc.

[0038] Figure 1 This is a block diagram illustrating details of an example wireless communication system according to one or more aspects. The wireless communication system may include a wireless network 100. Wireless network 100 may, for example, include a 5G wireless network. As those skilled in the art will recognize, Figure 1 The components appearing in this network are likely to have corresponding components in other network deployments (including, for example, cellular network deployments and non-cellular network deployments (e.g., device-to-device, peer-to-peer, or self-organizing network deployments)).

[0039] Figure 1The illustrated wireless network 100 includes multiple base stations 105 and other network entities. A base station can be a station communicating with a UE and may also be referred to as an evolved Node B (eNB), a next-generation eNB (gNB), and an access point, etc. Each base station 105 may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a specific geographic coverage area of ​​a base station or a base station subsystem serving that coverage area, depending on the context in which the term is used. In the specific implementation of the wireless network 100 herein, base stations 105 may be associated with the same operator or different operators (e.g., the wireless network 100 may include multiple operator wireless networks). Additionally, in the specific implementation of the wireless network 100 herein, base station 105 may use one or more frequencies (e.g., one or more bands of licensed spectrum, unlicensed spectrum, or combinations thereof) from the same frequencies as neighboring cells to provide wireless communication. In some examples, a single base station 105 or UE 115 may be operated by more than one network operating entity. In some other examples, each base station 105 and UE 115 may be operated by a single network operating entity.

[0040] Base stations can provide communication coverage for macro cells, small cells (such as pico cells or femto cells), or other types of cells. Macro cells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with service subscriptions to a network provider. Small cells (such as pico cells) typically cover a relatively small geographic area and allow unrestricted access by UEs with service subscriptions to a network provider. Small cells (such as femto cells) also typically cover a relatively small geographic area (e.g., a home) and, in addition to unrestricted access, provide restricted access by UEs associated with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG), UEs of users in a home, etc.). A base station for a macro cell may be referred to as a macro base station. A base station for a small cell may be referred to as a small cell base station, pico base station, femto base station, or home base station. Figure 1 In the example shown, base stations 105d and 105e are conventional macro base stations, while base stations 105a-105c are macro base stations implemented using one of 3D, full-dimensional (FD), or massive MIMO. Base stations 105a-105c utilize their higher-dimensional MIMO capabilities to employ 3D beamforming in elevation and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station, which can be a home node or a portable access point. A base station can support one or more (e.g., two, three, and four cells, etc.) cells.

[0041] Wireless Network 100 can support synchronous or asynchronous operation. For synchronous operation, base stations can have similar frame timings, and transmissions from different base stations can be roughly aligned in time. For asynchronous operation, base stations can have different frame timings, and transmissions from different base stations may not be aligned in time. In some scenarios, the network can be enabled or configured to handle dynamic switching between synchronous and asynchronous operations.

[0042] UE 115 is distributed throughout the wireless network 100, and each UE may be stationary or mobile. It should be understood that although mobile devices are generally referred to as UEs in standards and specifications issued by 3GPP, such devices may additionally or otherwise be referred to by those skilled in the art as mobile station (MS), subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal (AT), mobile terminal, radio terminal, remote terminal, handphone, terminal, user agent, mobile client, client, gaming device, augmented reality device, vehicle component, vehicle equipment or vehicle module, or some other suitable term. In this document, a “mobile” device or UE does not necessarily have the ability to move and may be stationary. Some non-limiting examples of mobile devices include specific implementations that may include one or more UEs in UE 115, including mobile phones, cellular phones (handphones), smartphones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, laptop computers, personal computers (PCs), notebooks, netbooks, smartbooks, tablet computers, and personal digital assistants (PDAs). Mobile devices can also be IoT or “Internet of Everything” (IoE) devices, such as automobiles or other transportation vehicles, satellite radios, Global Positioning System (GPS) devices, Global Navigation Satellite System (GNSS) devices, logistics controllers, drones, multi-rotor helicopters, quadcopter helicopters, smart energy or security devices, solar panels or solar arrays, urban lighting, water supply or other infrastructure; industrial automation and enterprise equipment; consumer and wearable devices, such as glasses, wearable cameras, smartwatches, health or fitness trackers, mammalian implantable devices, posture tracking devices, medical devices, digital audio players (e.g., MP3 players), cameras, game consoles, etc.; and digital home or smart home devices, such as home audio, video and multimedia equipment, appliances, sensors, vending machines, smart lighting, home security systems, smart meters, etc. In one aspect, a UE can be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, a UE can be a device that does not include a UICC. In some aspects, a UE that does not include a UICC can also be referred to as an IoE device. Figure 1The UEs 115a-115d illustrated herein are examples of mobile smartphone-type devices accessing the wireless network 100. The UE may also be a machine specifically configured for connecting communications, including machine-type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. Figure 1 The illustrated UE 115e-115k is an example of various machines configured for communication that access the wireless network 100.

[0043] Mobile devices (such as UE 115) can communicate with any type of base station (whether macro base station, pico base station, femto base station, or relay station). Figure 1 In this context, a communication link (represented by a lightning bolt) indicates radio transmission or expected transmission between the UE and a serving base station (which is designated to serve the UE on the downlink or uplink) and backhaul transmission between base stations. The UE may operate as a base station or other network node in some scenarios. Backhaul communication between base stations of the wireless network 100 can be performed using wired or wireless communication links.

[0044] In operation, at wireless network 100, base stations 105a-105c use 3D beamforming and cooperative spatial technologies such as Cooperative Multipoint (CoMP) or Multi-Connection to serve UEs 115a and 115b. Macro base station 105d performs backhaul communication with base stations 105a-105c and the small cell (base station 105f). Macro base station 105d also transmits multicast services subscribed to and received by UEs 115c and 115d. Such multicast services may include mobile TV or streaming video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber Alerts or Grey Alerts.

[0045] The implemented wireless network 100 supports mission-critical communication with highly reliable and redundant links for mission-critical devices such as UE 115e as a drone. Redundant communication links with UE 115e include links from macro base stations 105d and 105e, as well as small cell base station 105f. Other machine-type devices such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device) can communicate directly with base stations such as small cell base station 105f and macro base station 105e via the wireless network 100, or in a multi-hop configuration by communicating with another user device relaying its information to the network, such as UE 115f transmitting temperature measurement information to smart meter UE 115g, which then reports it to the network via small cell base station 105f. Wireless network 100 can also provide additional network efficiency through dynamic, low-latency TDD or low-latency FDD communication, such as in vehicle-to-vehicle (V2V) mesh networks between UEs 115i-115k communicating with macro base station 105e.

[0046] Figure 2 This is a block diagram illustrating an example of a base station 105 and a UE 115 according to one or more aspects. The base station 105 and the UE 115 can be... Figure 1 This refers to any one of the base stations and one of the UEs in the system. For restricted association scenarios (as mentioned above), base station 105 can be... Figure 1 The base station 105 is a small cell base station, and UE 115 can be UE 115c or 115d operating within the service area of ​​base station 105f. UE 115 will be included in the list of accessible UEs of small cell base station 105f in order to access it. Base station 105 can also be some other type of base station. Figure 2 As shown, base station 105 may be equipped with antennas 234a to 234t, and UE 115 may be equipped with antennas 252a to 252r for facilitating wireless communication.

[0047] At base station 105, transmitter processor 220 can receive data from data source 212 and control information from processor 240. The control information may be for physical broadcast channel (PBCH), physical control format indicator channel (PCFICH), physical hybrid ARQ (automatic repeat request) indicator channel (PHICH), physical downlink control channel (PDCCH), enhanced physical downlink control channel (EPDCCH), MTC physical downlink control channel (MPDCCH), etc. The data may be for physical downlink shared channel (PDSCH), etc. Furthermore, transmitter processor 220 can process (e.g., encoding and symbol mapping) data and control information separately to obtain data symbols and control symbols. Transmitter processor 220 can also generate, for example, reference symbols for primary synchronization signal (PSS) and secondary synchronization signal (SSS), as well as cell-specific reference signals. Transmit (TX) MIMO processor 230 can perform spatial processing (e.g., pre-decoding, where applicable) on data symbols, control symbols, or reference symbols, and can provide output symbol streams to modulators (MODs) 232a to 232t. For example, spatial processing performed on data symbols, control symbols, or reference symbols may include pre-decoding. Each modulator 232 may (e.g., for OFDM, etc.) process a corresponding output symbol stream to obtain an output sample stream. Alternatively or additionally, each modulator 232 may process the output sample stream (e.g., perform analog conversion, amplification, filtering, and up-conversion on it) to obtain a downlink signal. The downlink signal from modulators 232a to 232t may be transmitted via antennas 234a to 234t, respectively.

[0048] At UE 115, antennas 252a to 252r can receive downlink signals from base station 105 and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain the received symbols from demodulators 254a to 254r, perform MIMO detection on the received symbols when needed, and provide the detected symbols. Receiver processor 258 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide data decoded for UE 115 to data sink 260, and provide the decoded control information to processor 280 (such as a processor).

[0049] On the uplink, at UE 115, the transmitting processor 264 can receive and process data from data source 262 (e.g., for the Physical Uplink Shared Channel (PUSCH)) and control information from processor 280 (e.g., for the Physical Uplink Control Channel (PUCCH)). Additionally, the transmitting processor 264 can generate reference symbols for reference signals. Symbols from the transmitting processor 264 can be pre-decoded by the TX MIMO processor 266 when needed, further processed by modulators 254a to 254r (e.g., for SC-FDM, etc.), and transmitted to base station 105. At base station 105, the uplink signal from UE 115 can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 when needed, and further processed by receiving processor 238 to obtain the decoded data and control information transmitted by UE 115. Receiving processor 238 can provide the decoded data to data sink 239 and the decoded control information to processor 240.

[0050] Processors 240 and 280 can respectively direct operations at base station 105 and UE 115. Processor 240 or other processors and modules at base station 105, or processor 280 or other processors and modules at UE 115, can execute or direct the execution of various processes specific to the techniques described herein, such as executing or directing... Figure 5 and Figure 6 The illustrated execution or other processes relating to the techniques described herein. Memory 242 and memory 282 may store data and program code for base station 105 and UE 115, respectively. Scheduler 244 may schedule the UE to perform data transmission on the downlink or uplink.

[0051] In some cases, UE 115 and base station 105 may operate in a shared radio spectrum band, which may include licensed or unlicensed (e.g., contention-based) spectrum. In the unlicensed frequency portion of the shared radio spectrum band, UE 115 or base station 105 may conventionally perform a medium sensing procedure to compete for spectrum access. For example, UE 115 or base station 105 may perform a Listen-Before-Speak or Listen-Before-Transmit (LBT) procedure (such as Clear Channel Assessment (CCA)) before communication to determine if a shared channel is available. In some implementations, CCA may include an energy detection procedure to determine if any other active transmission is present. For example, the device may infer that a change in the Received Signal Strength Indicator (RSSI) of the power meter indicates that the channel is occupied. In particular, signal power concentrated in a certain bandwidth and exceeding a predetermined noise floor may indicate another radio transmitter. CCA may also include the detection of a specific sequence indicating channel usage. For example, another device may transmit a specific preamble before transmitting a data sequence. In some cases, the LBT process may include the wireless node adjusting its own backoff window based on the amount of energy detected on the channel or on acknowledgment / negative acknowledgment (ACK / NACK) feedback for packets it transmits (as a manifestation of a collision).

[0052] Figure 3 This is a block diagram illustrating an example of a wireless communication system 300 that indicates UE phase continuity based on support from one or more aspects. The wireless communication system 300 may include a UE 315 (such as UE 115). The wireless communication system 300 may also include one or more network nodes, such as network node 305. An example of a network node may be a base station, such as base station 105. A network node may also be referred to herein as a network entity. Depending on the example, a network node (or network entity) may be implemented as a base station, a network controller, an integrated access backhaul (IAB) node, a distributed unit (DU), a central unit (CU), a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU)), or one or more other components or entities, as illustrative examples.

[0053] Network node 305 may include one or more processors 302 (such as processor 240), memory 304 (such as memory 242), transmitter 306, and receiver 308. One or more processors 302 may be coupled to memory 304, transmitter 306, and receiver 308. In some examples, transmitter 306 and receiver 308 may include references. Figure 2The described components include one or more of the modulator / demodulator 232a-t, MIMO detector 236, receiver processor 238, transmitter processor 220, or TXMIMO processor 230. In some embodiments, transmitter 306 and receiver 308 may be integrated into one or more transceivers of network node 305.

[0054] Transmitter 306 can be configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and receiver 308 can be configured to receive reference signals, control information, and data from one or more other devices. For example, transmitter 306 can be configured to transmit signaling, control information, and data to UE 315, and receiver 308 can be configured to receive signaling, control information, and data from UE 315.

[0055] UE 315 may include one or more processors 352 (such as processor 280), memory 354 (such as memory 282), transmitter 356, and receiver 358. One or more processors 352 may be coupled to memory 354, transmitter 356, and receiver 358. In some examples, transmitter 356 and receiver 358 may include reference numerals. Figure 2 The described components include one or more of the modulator / demodulator 254a-r, MIMO detector 256, receiver processor 258, transmitter processor 264, or TX MIMO processor 266. In some embodiments, transmitter 356 and receiver 358 may be integrated into one or more transceivers of UE 315. In some examples, transmitter 356 may include power amplifier 370. In some examples, transmitter 356 and receiver 358 may include radar equipment (such as a monostatic radar transceiver) and may also include cellular equipment (such as a cellular transceiver).

[0056] Transmitter 356 can send reference signals, synchronization signals, control information, and data to one or more other devices, and receiver 358 can receive reference signals, control information, and data from one or more other devices. For example, in some implementations, transmitter 356 can send signaling, control information, and data to network node 305, and receiver 358 can receive signaling, control information, and data from network node 305.

[0057] The wireless communication system 300 may use wireless communication channels, which may be specified by one or more wireless communication protocols, such as the 5G NR wireless communication protocol. For example, network node 305 may use one or more downlink wireless communication channels (such as via one or more of PDSCH or PDCCH) to communicate with UE 315. UE 315 may use one or more uplink wireless communication channels (such as via one or more of PUSCH or PUCCH) to communicate with network node 305. Alternatively or otherwise, UE 315 may communicate with one or more other UEs, such as via sidelink wireless communication channels.

[0058] In some specific implementations, UE 315 may correspond to Figure 1 One of the illustrated UEs 115e, 115i, 115k, or 115j can be a means of transportation, such as an autonomous vehicle, a partially autonomous vehicle, or a non-autonomous vehicle. For further illustration, in some specific implementations, UE 315 can correspond to a wheeled vehicle (such as a car, truck, or motorcycle), a rail vehicle (such as a train or tram), a water vehicle (such as a ship, boat, or underwater vehicle), an aircraft vehicle, or a spacecraft vehicle. In some other examples, UE 315 can correspond to another device, such as a drone, robot, or sensor device, such as an Internet of Things (IoT) sensor device, as an illustrative example. In some examples, UE 315 can correspond to... Figure 1 One of UE 115f, 115g and 115h.

[0059] During operation, UE 315 may perform one or more joint sensing operations. An example of a joint sensing operation is a joint communication and radar sensing (JCR) operation. Performing a joint sensing operation (such as a JCR operation) may include performing one or more cellular communication operations and one or more sensing operations. For illustration, in some specific implementations, UE 315 may include or may be a vehicle, and the one or more sensing operations may include estimating one or more of the location, speed, acceleration, or other parameters of UE 315 or another UE, vehicle, or object.

[0060] For further illustration, UE 315 may perform a joint sensing operation 360 (e.g., a JCR operation), which includes multiple operations such as cellular communication 362 and sensing operation 364. In some examples, performing cellular communication 362 includes communicating with network node 305, such as by sending data or other signaling to network node 305, receiving data or other signaling from network node 305, or both. In some examples, sensing operation 364 may include estimating one or more of the location, speed, acceleration, or other parameters of UE 315 or another UE, vehicle, or object.

[0061] For illustration, performing sensing operation 364 may include transmitting a sensing reference signal (SRS) 320 (also referred to as a sensor reference signal). UE 315 may use resources (e.g., uplink resources) of a cellular band, such as a millimeter-wave (mmWave) band, to transmit SRS 320. For further illustration, in some examples, the cellular band may be associated with a center frequency of 28 GHz, 77 GHz, or another frequency. Resources may be configured, allocated, or scheduled by network node 305. In some specific implementations, SRS 320 may include cellular signal waveforms (such as cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) signal waveforms) or non-cellular signal waveforms.

[0062] Performing sensing operation 364 may also include receiving one or more reflections from SRS 320, such as reflection 322. UE 315 may estimate one or more of the location, speed, acceleration, or other parameters of UE 315 or another UE, vehicle, or object. In some examples, SRS 320 may include radar signals, and UE 315 may use Doppler sensing techniques to estimate location, speed, acceleration, or other parameters. Alternatively or in addition, in some other aspects, one or more other sensing signals or one or more other sensing techniques, such as ultrasonic signals and ultrasonic sensing techniques, may be used.

[0063] In some examples, UE 315 may use one or more components of UE 315 to perform both (or a portion thereof) cellular communication 362 and sensing operation 364, which may be referred to herein as jointly performing cellular communication 362 and sensing operation 364 (or a portion thereof). For illustration, in some examples, UE 315 may use a wireless communication device of UE 315 to jointly perform cellular communication 362 and sensing operation 364. The wireless communication device may include one or both of transmitter 356 and receiver 358. In some examples, the wireless communication device includes or corresponds to a transceiver including transmitter 356 and receiver 358. UE 315 may use the wireless communication device to transmit SRS 320 (e.g., via transmitter 356) and receive reflection 322 (e.g., via receiver 358).

[0064] To further illustrate, Figure 4 This is an illustration of a graph 400 that can be used to support indication of UE phase continuity based on one or more aspects. In graph 400, the horizontal axis may indicate time, and the vertical axis may indicate a quantity (e.g., signal energy or power). In some examples, transmission... Figure 3 The SRS 320 may include transmitting one or more SRS pulses, such as SRS pulses 320a, 320b, 320c, 320d, and 320e (also referred to as SRS pulses 320a-e). Execution Figure 3 The sensing operation 364 may include transmitting SRS pulses 320a-e and detecting one or more reflections (such as reflection 322) of the SRS pulses 320a-e. The UE 315 may use time-domain resources (such as OFDM symbols associated with a wireless communication protocol) and further use frequency-domain resources (such as “comb” type mappings of frequency-domain resources) to transmit each of the SRS pulses 320a-e.

[0065] UE 315 may transmit SRS pulses 320a-e during processing interval 404. In some specific implementations, processing interval 404 may be a coherent processing interval (CPI) or another processing interval. In some examples, the duration of processing interval 404 may be selected based on one or more criteria (e.g., by network node 305 or by UE 315). For example, the duration of processing interval 404 may be selected based on parameters that will be measured or estimated by UE 315. As a non-limiting illustrative example, UE 315 estimates velocity based on a specific duration of processing interval 404 to achieve at least a threshold accuracy (or resolution) level for the estimated velocity.

[0066] Each of SRS pulses 320a-e can be associated with a corresponding SRS interval that includes an SRS pulse transmission interval and a gap interval. For example, SRS pulse 320a can be associated with SRS interval 402, which includes the SRS pulse transmission interval during which UE 315 transmits SRS pulse 320a, and also includes a gap interval 408 that follows the transmission of SRS pulse 320a and precedes the transmission of SRS pulse 320b. In some examples, the gap intervals can be uniform or approximately uniform, where the gap intervals are equal or approximately equal. In some other examples, the gap intervals can be non-uniform.

[0067] UE 315 may perform one or more operations during one or more gap intervals, such as transmitting or receiving one or more signals 406 during gap interval 408. In some examples, one or more signals 406 may be associated with cellular communication 362 and may include one or more of a downlink signal received from network node 305, an uplink signal transmitted to network node 305, a sidelink signal received from another UE, or a sidelink signal transmitted to another UE, as illustrative examples. Alternatively or in addition, UE 315 may perform one or more other operations during gap interval 408, such as operating according to a sleep mode (e.g., by placing transmitter 356 into sleep mode) or performing beam switching operations (e.g., by adjusting transmitter 356 from using a first beam direction associated with SRS pulse 320a to using a second beam associated with SRS pulse 320b). In some specific implementations, processing time intervals 410 and 412 enable UE 315 to change or configure one or more parameters, such as by changing from a transmitting state to a receiving state (or vice versa), as illustrative examples.

[0068] In some cases, performing one or more operations during one or more gap intervals (such as gap interval 408) of processing interval 404 can be associated with a reduction or loss of phase continuity associated with SRS 320. As an illustrative example, after transmitting or receiving one or more signals 406, the phase of SRS pulse 320b may differ from the phase of SRS pulse 320a. Therefore, in some cases (such as if the phase difference between SRS pulses 320a and 320b is relatively large), the accuracy of estimating operations (such as positioning, velocity, or acceleration operations) may be reduced.

[0069] Refer again Figure 3Before performing the joint sensing operation 360, UE 315 may send a message 330 including an indication 332 associated with maintaining the phase continuity of SRS 320 (e.g., a UE phase continuity capability report or another message). For example, indication 332 may specify whether UE 315 (or one or more components of UE 315, such as transmitter 356 or receiver 358) is able to maintain the phase continuity of SRS 320 during processing interval 404. Figure 4 The indication 332 specifies (or may be associated with) whether UE 315 is able to maintain at least a threshold amount of phase continuity (e.g., at least a certain percentage of phase continuity) between two or more of the SRS pulses 320a-e. For example, indication 332 may specify (or may be associated with) whether UE 315 is able to maintain at least a threshold amount of phase continuity between consecutive SRS pulses (such as SRS pulses 320a and 320b). In another example, indication 332 may specify (or may be associated with) whether UE 315 is able to maintain at least a threshold amount of phase continuity between the initial SRS pulse and the final SRS pulse of a processing interval (such as SRS pulses 320a and 320e of processing interval 404).

[0070] In some examples, indication 332 may include a value, bit, flag, or other parameter indicating whether UE 315 is able to maintain at least a threshold amount of phase continuity associated with SRS 320 during processing interval 404. For example, indication 332 may include a value, bit, or flag that, when included in message 330, indicates that UE 315 can (or cannot) maintain at least a threshold amount of phase continuity. In some other examples, indication 332 may include a value, bit, or flag that, when not included in message 330, indicates that UE 315 can (or cannot) maintain at least a threshold amount of phase continuity. Alternatively or additionally, indication 332 may specify an amount (such as a percentage) of phase continuity supported by UE 315.

[0071] In some examples, indication 332 may specify whether UE 315 supports maintaining phase continuity for one or more specific operations or conditions. For example, indication 332 may specify whether UE 315 supports beam switching during processing interval 404 while maintaining phase continuity, such as by indicating whether UE 315 supports interleaving of the beam associated with SRS 320 and at least one other beam (such as the beam associated with one or more signals 406). As an illustrative example, indication 332 may specify whether UE 315 supports transmitting uplink signals in one or more signals 406 while maintaining phase continuity associated with SRS 320. Alternatively or otherwise, indication 332 may specify whether UE 315 supports changing bandwidth during processing interval 404 while maintaining phase continuity. For example, indication 332 may specify whether UE 315 supports changing from the transmission bandwidth associated with SRS 320 to another bandwidth associated with one or more signals 406 while maintaining phase continuity. Alternatively or otherwise, indication 332 may specify whether UE 315 supports receiving (or monitoring) another signal (such as a downlink signal from network node 305 or a sidelink signal from another UE) while maintaining phase continuity during processing interval 404. In some examples, indication 332 may use the number of slots or symbols to specify such information, such as the number of slots or symbols associated with downlink or sidelink signals that the UE supports or does not support maintaining phase continuity of SRS 320.

[0072] In some examples, indication 332 may specify whether UE 315 supports maintaining phase continuity for a specific duration, or may indicate a threshold duration during which UE 315 supports maintaining phase continuity, such as a maximum duration during which UE 315 supports maintaining phase continuity or a minimum duration during which UE 315 does not support maintaining phase continuity. For further illustration, indication 332 may specify whether UE 315 supports maintaining phase continuity while processing interval 404 for a specific duration. In some examples, this duration may correspond to the duration of processing interval 404, such as by indicating the number of SRS pulses that UE 315 can maintain phase continuity with. In some examples, the duration may be indicated via the time interval between the initial OFDM symbol and the final OFDM symbol of SRS 320, or between the initial OFDM symbol and the final OFDM symbol.

[0073] In some examples, instruction 332 can specify Figure 4The duration of the gap interval 408 can indicate whether UE 315 supports maintaining phase continuity for a specific duration of the gap interval 408. For illustration, in some implementations, a longer duration of the gap interval 408 may be associated with a greater phase loss (or the probability of phase loss) from SRS pulse 320a to SRS pulse 320b (even if UE 315 does not transmit or receive one or more signals 406 during the gap interval 408). For further illustration, in some examples, SRS 320 may be associated with at least a first SRS pulse (such as SRS pulse 320a or another SRS pulse) and a second SRS pulse (such as a second SRS pulse or another SRS pulse) separated from the first SRS pulse by the gap interval (such as gap interval 408), and indication 332 may specify whether UE 315 supports maintaining phase continuity for a specific duration of the gap interval. In some implementations, the duration of the gap interval 408 may be related to a subcarrier spacing (SCS) parameter associated with SRS 320, and this duration may be indicated in conjunction with the SCS.

[0074] In some examples, indication 332 may specify the duration of one or more processing time intervals, such as the duration of processing time interval 410, the duration of processing time interval 412, or a combination thereof. For illustration, in some examples, UE 315 may perform operations during a gap interval (such as gap interval 408) associated with an interruption of transmission state 372 of transmitter 356. Transmission state 372 may be associated with the transmission of SRS 320. For example, transmission state 372 may include one or more of a phase associated with SRS 320 or a power amplifier state (e.g., signal amplification) of power amplifier 370 for amplifying SRS 320. UE 315 may, for example, store an indication of transmission state 372 at memory 354 (e.g., before interrupting transmission state 372 to perform operations). UE 315 may select the duration of gap interval 408 so that UE 315 is able to retrieve transmission state 372 (e.g., from memory 354) and restore the retrieved transmission state 372 at transmitter 356. In one example, instruction 332 may specify the duration of processing time interval 412 for restoring transmission state 372 before gap interval 408 is completed, control information 340 may indicate time resources associated with the operation, and the time resources may be based on the duration of processing time interval 412. UE 315 may perform the operation based on the time resources (e.g., when using processing time interval 412 to restore transmission state 372).

[0075] In some examples, network node 305 and UE 315 may communicate using a wireless communication protocol that specifies one or more features associated with indication 332. For example, the wireless communication protocol may specify that indication 332 will be provided by a UE capable of transmitting SRS for sensing (such as SRS 320). In some other examples, the wireless communication protocol may specify that indication 332 will be provided by a UE capable of transmitting and using SRS for specific operations (such as for speed estimation).

[0076] Network node 305 can select resources 342 associated with processing interval 404 and can send (e.g., before UE 315 performs joint sensing operation 360) control information 340 indicating resources 342. Control information 340 may include allocation, configuration, or scheduling of resources 342 according to indication 332. For illustration, control information 340 may indicate one or more of the following according to indication 332: the duration of the configured processing interval 404; the duration of the configured gap interval (such as the duration of the configured gap interval 408); the interleaving or non-interleaving of the beam associated with SRS 320 and at least one other beam; one or more configured resources for another transmission during the processing interval (such as the transmission of one or more signals 406); or the allocation of uplink resources for the transmission of SRS 320. For example, control information 340 may indicate uplink resources according to indication 332, specifying whether UE 315 supports maintaining phase continuity while monitoring or receiving another signal (such as using downlink resources, sidelink resources, or a combination thereof). In some examples, downlink resources may include one or more of a first set of downlink resources that are common to UEs in the same cell or a second set of downlink resources that are associated with the UE.

[0077] For further illustration, if instruction 332 specifies that UE 315 supports (or does not support) beam switching during processing interval 404 while maintaining phase continuity, resource 342 may include multiple beams for beam switching during processing interval 404 (or a single beam for avoiding beam switching during processing interval 404). Alternatively or additionally, if instruction 332 specifies that UE 315 supports (or does not support) changing transmission bandwidth during processing interval 404 while maintaining phase continuity, resource 342 may include multiple different transmission bandwidths for transmission bandwidth adjustment during processing interval 404 (or a single transmission bandwidth for avoiding transmission bandwidth adjustment during processing interval 404). Alternatively or additionally, if instruction 332 specifies that UE 315 supports (or does not support) receiving another signal (such as a downlink signal from network node 305 or a sidelink signal from another UE) while maintaining phase continuity during processing interval 404, resource 342 may include one or more of downlink resources or sidelink resources for one or more receive operations during processing interval 404 (or such downlink or sidelink resources may be excluded if UE 315 does not support receiving such a signal while maintaining phase continuity during processing interval 404). Alternatively or additionally, resource 342 may include time resources selected based on the duration specified by instruction 332 (e.g., such that the duration of processing interval 404 does not exceed the duration during which UE 315 can maintain phase continuity). Other examples are also within the scope of this disclosure.

[0078] UE 315 may receive control information 340. UE 315 may perform joint sensing operations 360 based on the control information 340, such as by using resources 342 indicated by the control information 340. For example, UE 315 may transmit SRS 320 based on the control information 340 during processing interval 404, such as by using resources 342 indicated by the control information 340. UE 315 may receive reflections 322 of the SRS 320 and may estimate one or more parameters (such as one or more of positioning, velocity, or acceleration) associated with one or more of UE 315, another UE, or another object based on the reflections 322.

[0079] In some cases, control information received by UE 315 (such as control information 340) may indicate one or more parameters that contradict indication 332, such as if UE 315's capabilities change after message 330 is sent, or if network node 305 is unable to schedule, allocate, or configure resource 342 according to indication 332 due to resource unavailability. UE 315 may determine whether to send SRS according to one or more parameters based on one or more criteria. In some implementations, the one or more criteria may specify that UE 315 will send SRS 320 according to the one or more parameters (if UE 315 is able to do so) or will avoid sending SRS 320 according to the one or more parameters. In some other examples, the one or more criteria may be specific to UE 315 (e.g., through configuration by UE 315's vendor) or may be specified by the wireless communication protocol associated with wireless communication system 300.

[0080] In some examples, the phase continuity associated with indication 332 may be measured (or indicated) according to one or more phase continuity measures. For illustration, these one or more phase continuity measures may include a percentage or degree of phase difference between two or more SRS pulses (such as SRS pulses 320a and 320b or SRS pulses 320a and 320e) associated with SRS 320. Phase difference may also be referred to as phase offset or phase “drift.” Alternatively or in addition, to express phase continuity using phase difference, one or more other measures may be used, such as using frequency offset, where the frequency offset is caused by a phase difference less than a specific percentage of the carrier frequency associated with SRS 320. In some specific implementations, these one or more phase continuity measures may be specific to UE 315 (e.g., through configuration by the vendor of UE 315). In some other examples, these one or more phase continuity measures may be specified by the wireless communication protocol associated with the wireless communication system.

[0081] One or more aspects described herein can improve the operation of one or more devices within a wireless communication system (such as wireless communication system 300). For example, because some sensing operations may be relatively sensitive to the phase of SRS 320, avoiding one or more operations that may change or degrade the phase from one SRS pulse to another can improve the phase continuity between pulses of SRS 320, thereby improving the accuracy of such sensing operations. Therefore, by specifying the ability of UE 315 to maintain the phase continuity associated with SRS 320 via indication 332, the reliability of sensing operations at UE 315 can be improved.

[0082] Alternatively or otherwise, improved accuracy can reduce or eliminate the need for certain circuitry that may be relatively expensive or complex to implement. For example, some operations performed between pulses of SRS 320 may use dedicated hardware or other circuitry of UE 315, such as hardware or circuitry that facilitates beam-switching operations or operations based on sleep modes. By instructing network node 305 via indication 332 that UE 315 supports phase continuity, network node 305 can avoid allocating, configuring, or scheduling resources for such operations between pulses of SRS 320. Therefore, the use of such hardware or circuitry can be reduced or eliminated, thereby lowering the cost and complexity associated with UE 315.

[0083] Figure 5 This is a flowchart illustrating an example procedure 500 for instructing UE phase continuity based on support from one or more aspects. In some examples, UE 315 performs procedure 500.

[0084] Process 500 includes sending a message at 502 that includes an indication to maintain the phase continuity of the sensing reference signal (SRS) during a processing interval associated with the joint sensing operation. For example, UE 315 may send message 330 that includes an indication 332 associated with maintaining the phase continuity of SRS 320 during a processing interval 404 associated with the joint sensing operation 360.

[0085] The process 500 also includes receiving control information associated with the indication at 504. For example, UE 315 may receive control information 340 associated with indication 332.

[0086] Figure 6 This is a flowchart illustrating another example of a process 600 that instructs UE phase continuity based on support from one or more aspects. In some examples, network node 305 performs process 600.

[0087] Process 600 includes receiving a message at 602 that includes an indication to the user equipment (UE) to maintain phase continuity of the sensing reference signal (SRS) during a processing interval associated with joint sensing operation. For example, network node 305 may receive message 330 that includes an indication 332 associated with UE 315 maintaining phase continuity of SRS 320 during a processing interval 404 associated with joint sensing operation 360.

[0088] Process 600 also includes sending control information associated with the instruction at 604. For example, network node 305 may send control information 340 associated with instruction 332.

[0089] Figure 7This is a block diagram illustrating an example of a UE 315 according to some aspects of this disclosure. The UE 315 may include a processor 280 capable of executing instructions stored in a memory 282. Using the processor 280, the UE 315 may transmit and receive signals via wireless radio components 701a-r and antennas 252a-r. The wireless radio components 701a-r may include one or more components or devices described herein, such as modulators / demodulators 254a-r, MIMO detectors 256, receive processors 258, transmit processors 264, TX MIMO processors 266, transmitters 356, receivers 358, one or more other components or devices, or combinations thereof.

[0090] In some examples, memory 282 may store instructions executable by one or more processors (e.g., processor 280), which are individually or collectively configured to initiate, execute, or control one or more operations described herein.
