Abstract
Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims the benefit of Greek patent application serial number 20220101088, filed on December 29, 2022, entitled “SENSING RESOURCE POOLPRECONFIGURATION,” which is expressly incorporated herein by reference in its entirety. Technical Field
[0003] The present disclosure relates generally to communication systems, and more particularly to configuration of a sensing resource pool for single-phase or multi-phase sensing using uplink resources. Background Art
[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continued mobile broadband evolution promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)) and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Certain aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. In addition, these improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the Invention
[0006] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of these aspects. This summary is not an extensive overview of all contemplated aspects. This summary does not identify key or critical elements of all aspects, nor does it delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that will be presented later.

The apparatus receives a sensing resource pool configuration for using uplink resources for a joint communication and radar system, wherein the sensing resource pool configuration is based on at least one of time resource allocation, space resource allocation, or frequency resource allocation. The apparatus performs sensing operations based on the sensing resource pool configuration.
[0008] To achieve the foregoing and related ends, one or more aspects include the features fully described below and particularly pointed out in the claims.

[0025] In wireless communication systems, systems such as joint communication and radar (JCR) systems can be classified as collaborative JCR systems or collaborative design of communication and radar systems. In a collaborative JCR system, some knowledge is shared between the communication system and the radar system in an effort to improve their performance. The advantages of a collaborative JCR system may include spectrum reuse and ease of implementation. In the collaborative design of a communication and radar system, a common transmitter or receiver may be used for both communication functionality and radar functionality. The advantages of collaborative design of a communication and radar system may include hardware and spectrum reuse. Automotive applications may utilize a single-phase sensing operation, which may require a high-density on-board radar with high resolution and high update rate. However, a single-phase sensing operation may result in a large communication overhead. In some cases, automotive applications may utilize a two-phase sensing operation including a scanning phase and a tracking phase. The scanning phase may have a lower resolution to detect the presence of obstacles or vehicles (e.g., in automotive applications), and the tracking phase may have a higher resolution than the scanning phase for fine target detection. Any obstacles or vehicles detected during the scanning phase will be tracked during the tracking phase.
[0026] Various aspects generally relate to configuration of a sensing resource pool for single-phase or two-phase sensing using uplink resources. Compared to single-phase sensing operation, two-phase sensing operation using a scanning phase and a tracking phase can achieve radar sensing with low overhead.
[0027] At least one advantage of the present disclosure is that two-phase sensing can allow for multiple radar sensing on shared uplink communication resources with low overhead. At least one advantage of configuring a sensing resource pool for two-phase sensing is reduced overhead, which can improve performance.
[0028] The detailed description set forth below in conjunction with the accompanying drawings is a description of various configurations and does not represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of the various concepts. However, these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring the concepts.
[0029] Several aspects of telecommunication systems are presented with reference to various apparatuses and methods. These apparatuses and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0030] As an example, an element or any part of an element or any combination of elements can be implemented as a "processing system", which includes one or more processors. The example of a processor includes a microprocessor, a microcontroller, a graphics processing unit (GPU), a central processing unit (CPU), an application processor, a digital signal processor (DSP), a reduced instruction set computing (RISC) processor, a system on a chip (SoC), a baseband processor, a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, a gating logic, a discrete hardware circuit and other suitable hardware configured to perform various functionalities described throughout the present disclosure. One or more processors in a processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language or other terms, software should be broadly interpreted as meaning an instruction, an instruction set, a code, a code segment, a program code, a program, a subroutine, a software component, an application, a software application, a software package, a routine, a subroutine, an object, an executable file, a thread of execution, a process, a function or any combination thereof.
[0031] Thus, in one or more example aspects, specific implementations and / or use cases, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. A storage medium may be any available medium that can be accessed by a computer. As an example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of these types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.
[0032] Although various aspects, specific implementations and / or use cases are described in this application by way of illustration of some examples, additional or different aspects, specific implementations and / or use cases may be generated in many different arrangements and scenarios. The various aspects, specific implementations and / or use cases described herein may be implemented across many different platform types, devices, systems, shapes, sizes and packaging arrangements. For example, various aspects, specific implementations and / or use cases may be generated via integrated chip implementations and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, devices that enable artificial intelligence (AI), etc.). Although some examples may or may not be specifically for use cases or applications, the examples described may have a wide range of applicability. Various aspects, specific implementations and / or use cases may be within the scope of chip-level or modular components to non-modular, non-chip-level implementations, and further to the scope of aggregation, distribution or original equipment manufacturer (OEM) equipment or systems in conjunction with one or more technologies herein. In some actual settings, the equipment in conjunction with the various aspects and features described may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily include multiple components for both analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The techniques described herein can be practiced in a wide variety of devices of various sizes, shapes, and configurations, including chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, and the like.
[0033] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways with various components or parts. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element or network equipment (such as a base station (BS)) or one or more units (or one or more components) that perform base station functions can be implemented in a converged or decomposed architecture. For example, a BS (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmit receive point (TRP) or a cell, etc.) can be implemented as a converged base station (also known as a standalone BS or a monolithic BS) or a decomposed base station.
[0034] A converged base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack that is physically or logically distributed between two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).
[0035] Base station operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (a network configuration such as that initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Disaggregation may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Various units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.
[0036] Figure 1FIG1 is a diagram 100 illustrating an example of a wireless communication system and access network. The illustrated wireless communication system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that may communicate directly with a core network 120 via a backhaul link, or indirectly with the core network 120 through one or more disaggregated base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 125 via an E2 link, or a non-real-time (non-RT) RIC 115 associated with a service management and orchestration (SMO) framework 105, or both. The CU 110 may communicate with one or more DUs 130 via corresponding midhaul links, such as an F1 interface. The DU 130 may communicate with one or more RUs 140 via corresponding fronthaul links. The RU 140 may communicate with corresponding UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.
[0037] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller that provides instructions to the communication interfaces of these units, may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive and / or transmit signals to one or more of the other units via a wireless transmission medium.
[0038] In some aspects, the CU 110 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 110. The CU 110 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, the CU 110 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 110 may be implemented to communicate with the DU 130 for network control and signaling.
[0039] The DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 140. In some aspects, the DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more higher physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) based at least in part on a functional split, such as those defined by 3GPP. In some aspects, the DU 130 may further host one or more lower PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 130 or with control functions hosted by the CU 110.
[0040] Lower layer functionality may be implemented by one or more RUs 140. In some deployments, a RU 140 controlled by a DU 130 may correspond to a logical node that hosts RF processing functionality or low PHY layer functionality (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some implementations, both real-time and non-real-time aspects of control plane and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration may enable the DU 130 and CU 110 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).
[0041] The SMO framework 105 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 105 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 105 can be configured to interact with a cloud computing platform (such as Open Cloud (O-Cloud) 190) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements may include, but are not limited to, the CU 110, DU 130, RU 140, and near-RT RIC 125. In some implementations, the SMO framework 105 can communicate with hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 111) via the O1 interface. Additionally, in some implementations, the SMO framework 105 can communicate directly with one or more RUs 140 via the O1 interface. The SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of the SMO framework 105 .
[0042] The non-RT RIC 115 may be configured to include logic that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 125. The non-RT RIC 115 may be coupled to or in communication with the near-RT RIC 125 (e.g., via an A1 interface). The near-RT RIC 125 may be configured to include logic that enables near-real-time control and optimization of RAN elements and resources through data collection and actions over an interface (e.g., via an E2 interface) that connects one or more CUs 110, one or more DUs 130, or both, and an O-eNB with the near-RT RIC 125.
[0043] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 125, the non-RT RIC 115 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 125 and can be received from non-network data sources or from network functions at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 can be configured to regulate RAN behavior or performance. For example, the non-RT RIC 115 can monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).
[0044] At least one of the CU 110, DU 130, and RU 140 may be referred to as a base station 102. Thus, the base station 102 may include one or more of the CU 110, DU 130, and RU 140 (each component is indicated by a dotted line to indicate that each component may or may not be included in the base station 102). The base station 102 provides an access point to the core network 120 for the UE 104. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). Small cells include femto cells, pico cells, and micro cells. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which may provide services to a restricted group called a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) (also known as reverse link) transmissions from UE 104 to RU 140 and / or downlink (DL) (also known as forward link) transmissions from RU 140 to UE 104. The communication link may utilize multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may be over one or more carriers. For each carrier allocated in a carrier aggregation for a total of up to Yx MHz (x component carriers) for transmission in each direction, base station 102 / UE 104 may utilize spectrum with a bandwidth of up to Y MHz (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.). These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL compared to UL). Component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).
[0045] Some UEs 104 may communicate with each other using device-to-device (D2D) communication links 158. The D2D communication links 158 may use DL / UL wireless wide area network (WWAN) spectrum. The D2D communication links 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication may be accomplished through various wireless D2D communication systems, such as, for example, Bluetooth, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.
[0046] The wireless communication system may also include a Wi-Fi AP 150 that communicates with a UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in the 5 GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the UE 104 / AP 150 may perform a clear channel assessment (CCA) to determine whether the channel is available before communicating.
[0047] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).
[0048] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6GHz-71GHz), FR4 (71GHz-114.25GHz), and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.
[0049] With the above in mind, unless otherwise specified, if the term "sub-6 GHz" or the like is used herein, it may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless otherwise specified, if the term "millimeter wave" or the like is used herein, it may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.
[0050] Base station 102 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. Base station 102 may transmit beamformed signals 182 to UE 104 in one or more transmit directions. UE 104 may receive beamformed signals from base station 102 in one or more receive directions. UE 104 may also transmit beamformed signals 184 to base station 102 in one or more transmit directions. Base station 102 may receive beamformed signals from UE 104 in one or more receive directions. Base station 102 / UE 104 may perform beam training to determine the optimal receive and transmit directions for each of base station 102 / UE 104. The transmit and receive directions of base station 102 may or may not be the same. The transmit and receive directions of UE 104 may or may not be the same.
[0051] The base station 102 may include and / or be referred to as a gNB, a Node B, an eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit / receive point (TRP), a network node, a network entity, a network equipment, or some other suitable terminology. The base station 102 may be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, a converged (monolithic) base station having a baseband unit (BBU) (including a CU and a DU) and a RU, or as a disaggregated base station including one or more of a CU, a DU, and / or a RU. A collection of base stations that may include disaggregated base stations and / or converged base stations may be referred to as a next generation (NG) RAN (NG-RAN).
[0052] The core network 120 may include an access and mobility management function (AMF) 161, a session management function (SMF) 162, a user plane function (UPF) 163, a unified data management (UDM) 164, one or more location servers 168, and other functional entities. The AMF 161 is a control node that handles signaling between the UE 104 and the core network 120. The AMF 161 supports registration management, connection management, mobility management, and other functions. The SMF 162 supports session management and other functions. The UPF 163 supports packet routing, packet forwarding, and other functions. The UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identity handling, access authorization, and subscription management. The one or more location servers 168 are exemplified as including a gateway mobile location center (GMLC) 165 and a location management function (LMF) 166. However, in general, the one or more location servers 168 may include one or more location / positioning servers, which may include one or more of the GMLC 165, LMF 166, Position Determination Entity (PDE), Serving Mobile Location Center (SMLC), Mobile Positioning Center (MPC), etc. The GMLC 165 and LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and UE 104 via the AMF 161 to calculate the location of the UE 104. The NG-RAN may utilize one or more positioning methods to determine the location of the UE 104. Positioning the UE 104 may involve signal measurements, position estimation, and optional velocity calculation based on these measurements. Signal measurements may be performed by the UE 104 and / or the serving base station 102. The measured signals may be based on one or more of a satellite positioning system (SPS) 170 (e.g., a global navigation satellite system (GNSS), a global positioning system (GPS), a non-terrestrial network (NTN), or other satellite positioning / positioning systems), LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS), sensor-based information (e.g., an atmospheric pressure sensor, a motion sensor), an NR enhanced cell ID (NR E-CID) method, NR signals (e.g., multi-round trip time (multi-RTT), DL angle of departure (DL-AoD), DL time difference of arrival (DL-TDOA), UL time difference of arrival (UL-TDOA), and UL angle of arrival (UL-AoA) positioning), and / or other systems / signals / sensors.
[0053] Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional device. Some of UE 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart rate monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also apply to one or more companion devices, such as in a device cluster arrangement. One or more of these devices may access the network collectively and / or individually.
[0054] Reference again Figure 1 In certain aspects, the UE 104 may include a sensing component 198 configured to: receive a sensing resource pool configuration for using uplink resources for a joint communication and radar system, wherein the sensing resource pool configuration is based on at least one of a time resource allocation, a space resource allocation, or a frequency resource allocation; and perform a sensing operation based on the sensing resource pool configuration.
[0055] Although the following description may focus on 5G NR, the concepts described herein may be applicable to other similar areas such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.
[0056] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D FIG280 is a diagram illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL, or may be time division duplex (TDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL. Figure 2A 、 Figure 2C In the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28, respectively, any particular subframe can be configured with any of the various available slot formats 0 to 61. Slot formats 0 and 1 are all DL and all UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. The slot format is configured for the UE via a received slot format indicator (SFI) (dynamically configured via DL control information (DCI) or semi-statically / statically configured via radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.
[0057] Figures 2A to 2D The frame structure is illustrated, and various aspects of the present disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10ms) can be divided into 10 equally sized subframes (1ms). Each subframe may include one or more time slots. A subframe may also include a mini-time slot, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For a normal CP, each time slot may include 14 symbols, and for an extended CP, each time slot may include 12 symbols. The symbols on the DL may be CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbols. The symbols on the UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) extended OFDM (DFT-s-OFDM) symbols (for power-limited scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and parameter set. The numerology defines the subcarrier spacing (SCS) (see Table 1). The symbol length / duration is scalable with 1 / SCS.
[0058]
[0059] Table 1: Parameter set, SCS and CP
[0060] For normal CP (14 symbols / slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Thus, for normal CP and parameter set μ, there are 14 symbols / slot and 2 μ time slots / subframe. The subcarrier spacing can be equal to 2 μ*15kHz, where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=4 is 240kHz. Symbol length / duration is inversely related to subcarrier spacing. Figures 2A to 2D An example is provided for a normal CP with 14 symbols per slot and a parameter set μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP may have a specific parameter set and CP (normal or extended).
[0061] A resource grid can be used to represent the frame structure. Each slot includes a resource block (RB) (also known as a physical RB (PRB)) that extends over 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.
[0062] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RSs may include a demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RSs may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).
[0063] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE groups (REGs), each REG comprising 12 consecutive REs within an OFDM symbol of a RB. The PDCCH within a BWP may be referred to as a control resource set (CORESET). During a PDCCH monitoring opportunity on the CORESET, the UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space), where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies across the channel bandwidth. The primary synchronization signal (PSS) may be within symbol 2 of a specific subframe of the frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. The secondary synchronization signal (SSS) may be within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as an SS block (SSB)). The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information not sent over the PBCH, such as the system information block (SIB), and paging messages.
[0064] like Figure 2C As illustrated, some of the REs carry DM-RS (indicated as R for a specific configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit the DM-RS of the physical uplink control channel (PUCCH) and the DM-RS of the physical uplink shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is transmitted and depending on the specific PUCCH format used, the PUCCH DM-RS may be transmitted in different configurations. The UE may transmit a sounding reference signal (SRS). The SRS may be transmitted in the last symbol of the subframe. The SRS may have a comb structure, and the UE may transmit the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.
[0065] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as a scheduling request, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.
[0066] Figure 3 3 is a block diagram of a base station 310 in an access network communicating with a UE 350. In the DL, Internet Protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0067] The transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functionality associated with various signal processing functions. Layer 1, which includes the physical (PHY) layer, may include error detection on transport channels, forward error correction (FEC) coding / decoding of transport channels, interleaving, rate matching, mapping onto physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles the mapping onto signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-order phase-shift keying (M-PSK), and M-order quadrature amplitude modulation (M-QAM). The coded and modulated symbols are then separated into parallel streams. Each stream is then mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying the time-domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. The channel estimates may be derived from a reference signal and / or channel state feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier using a corresponding spatial stream for transmission.
[0068] At the UE 350, each receiver 354Rx receives a signal via its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement Layer 1 functionality associated with various signal processing functions. The RX processor 356 performs spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined into a single OFDM symbol stream by the RX processor 356. The RX processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, as well as the reference signal, are recovered and demodulated by determining the most likely signal constellation point transmitted by the base station 310. These soft decisions may be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by base station 310. The data and control signals are then provided to a controller / processor 359, which implements layer 3 and layer 2 functionality.
[0069] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0070] Similar to the functionality described in conjunction with DL transmissions performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with delivery of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0071] Channel estimates derived by the channel estimator 358 based on a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.
[0072] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318Rx receives a signal through its corresponding antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to the RX processor 370.
[0073] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0074] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform operations related to Figure 1 Various aspects related to the sensing component 198.
[0075] In wireless communication systems, such as Joint Communication and Radar (JCR) systems can be classified as collaborative JCR systems or collaborative designs of communication and radar systems. Figure 4A 4 is a diagram of a collaborative JCR system. In the collaborative JCR system, some knowledge is shared between the communication system (e.g., communication tx / rx 402) and the radar system (e.g., radar tx / rx 404) in an effort to improve their performance without changing the core operations of the radar and communication systems. In some cases, knowledge can be shared between the communication system and the radar system between different users. For example, in Figure 4A In diagram 400, knowledge can be shared between the communication systems and radar systems of user A 406 and user B 408. Advantages of a collaborative JCR system may include spectrum reuse and ease of implementation. Figure 4B FIG4 is an illustration of a co-design of a communication and radar system 410. In the co-design of a communication and radar system, a common transmitter or receiver (eg, JCR tx / rx 412) may be used for both communication functionality and radar functionality. For example, referring to FIG4 Figure 4B 4, a common transmitter or receiver (e.g., JCR tx / rx 412) can be used for communication between user A 414 and user B 416. Co-design of communication and radar systems may require modifications in transmit waveform generation or receiver processing in either or both of the communication and radar systems. Advantages of co-design of communication and radar systems may include hardware and spectrum reuse.
[0076] refer to Figure 5500, sensing can be performed on uplink resources. For example, a vehicle UE 502 can sense surrounding objects (e.g., vehicles 504 and 506) for automotive applications, such as, but not limited to, collision avoidance. In some cases, the vehicle UE 502 can travel on the road at a rate of 12 m / s, while the vehicle 504 can travel on the road in the same direction as the vehicle UE 502 at a rate of 20 m / s, while the vehicle 506 is traveling on the road in the opposite direction at a rate of 20 m / s. The vehicle UE 502 can perform sensing operations via CP-OFDM 508 and can detect clutter echoes 510 from the vehicle 504 and clutter echoes 512 from the vehicle 506. In order to implement JCR sensing on the vehicle UE side, uplink resources can be reused for sensing. Uplink resources can be shared between communication mode and radar mode. For example, uplink resources can be separate resources for communication or radar, such as using time division multiplexing mode. In such cases, the SRS may be used as the sensing waveform or may be the same resource used for communication and radar with a joint co-designed waveform.
[0077] Figure 6 A diagram 600 of a single phase sensing operation is provided. Automotive applications may utilize single phase sensing operations, which may require a high density vehicle radar with high resolution and high update rate. For example, diagram 600 provides an example of single phase sensing with certain per frame requirements. A coherent processing interval (CPI) 602 may correspond to a radar frame. Figure 6 In the diagram 600, at f c At ΔR = 30 cm, for Δv = 0.4 m / s, the CPI per beam can be 5.1 ms, with a bandwidth of 0.5 GHz and an SCS of 120 kHz. Single-phase sensing operation with an update rate of 20 frames per second and a 50 ms sensing period can result in more than 10% of system resources being utilized per beam and per user. Consequently, single-phase sensing operation can result in significant communication overhead.
[0078] Figure 7A diagram 700 of a two-phase sensing operation is provided. The two-phase sensing operation may include a scanning phase 702 and a tracking phase 704. The scanning phase 702 may have a lower resolution to detect the presence of obstacles or vehicles, for example, in automotive applications. The scanning phase may include a scanning CPI 706, where the scanning CPI per beam is 1 ms for Δv = 2 m / s, ΔR = 1 m, the bandwidth is 150 MHz, and the SCS is 120 kHz. The tracking phase may have a higher resolution than the scanning phase for fine target detection. Any obstacles or vehicles detected during the scanning phase will be tracked during the tracking phase. The tracking phase may include a tracking CPI 708, where the tracking CPI per beam is 5 ms, the bandwidth is 0.5 GHz, and comb-5 sampling is used in time (e.g., 1 every 5 symbols) and comb-4 sampling is used in frequency (e.g., 1 every 4 REs). Two-phase sensing operation with an update rate of 20 frames per second can reduce system resources per user and per detected target to approximately 4.5%, resulting in a system resource reduction of approximately 9% per user when two targets are detected within the field of view of a device performing two-phase sensing operation. Thus, two-phase sensing operation using a scanning phase and a tracking phase can achieve radar sensing with low overhead compared to single-phase sensing operation. Two-phase sensing can enable multi-radar sensing on shared uplink communication resources with low overhead.
[0079] Single-phase sensing transmissions can be triggered as needed to meet the needs of certain applications, where a few target beam directions are to be sensed with low overhead. In two-phase sensing, the requirements for scanning (in all beam directions, unlike single-phase sensing) and tracking (based on the beam direction selected in the previous scanning phase) may be different. For example, the scanning phase can be used statically or semi-persistently for periodic sensing. Key performance indicators may include large unambiguous velocity estimates, long-range radar sensing, or a wide field of view, which may come at the expense of lower resolution. In addition, if a target, obstacle, vehicle, etc. has been detected in the scanning phase, the tracking phase can be triggered semi-persistently or dynamically after the scanning phase.
[0080] Various aspects presented herein provide for configuring a sensing resource pool for single-phase or two-phase sensing using uplink resources. At least one advantage of configuring a sensing resource pool for two-phase sensing is reduced overhead, which can improve performance. The sensing resource pool configuration can be based on time-space-frequency resource allocation or expected quality of service characteristics. At least another advantage is that different sensing resource pools can be configured for scanning and tracking.
[0081] In some aspects, a device configured to perform sensing (e.g., a UE) may receive a sensing resource pool configuration from another device (e.g., a base station), where the resource pool configuration may include one or more of: frequency comb (e.g., comb-2, comb-4, comb-6, etc.), time comb (e.g., comb-2, comb-4, comb-6, etc.), time periodicity, maximum frame, maximum bandwidth, azimuth and elevation beam limits (e.g., maximum effective isotropic radiated power (EIRP) in some elevation directions), or maximum transmit power.
[0082] In some aspects, the resource pool configuration may include an expected quality of service level for the sensing resource pool. The quality of service characteristics may include one or more of a maximum or minimum supported detection range, velocity, or angular direction; resolution or estimation accuracy in the distance-velocity-angle domain; update rate; latency (e.g., the time interval between a resource reservation request and the start time of transmission); probability of detection or false alarm at the maximum supported distance-velocity-angle; or priority index (e.g., a high priority index may indicate increased priority relative to a lower priority index).
[0083] In some aspects, the resource pool configuration can be configured to include separate pools for the scanning phase and the tracking phase. For example, the resource pool configuration for the scanning phase can include resources that cater to scanning resources, such as, but not limited to, a small bandwidth for low range resolution, a wide beam for low latency scanning or short distance scanning, a narrow beam for long distance scanning, a total duration for low velocity resolution, a comb size in time for a larger maximum unambiguous velocity estimate, or a comb size in range for a larger maximum unambiguous range estimate.
[0084] The resource pool configuration for the tracking phase may include resources that cater to tracking resources, such as, but not limited to, large bandwidth for high range resolution, narrow beam for target tracking of targets detected during the scanning phase, total duration for high velocity resolution, comb size in time for efficient resource utilization (e.g., velocity can be estimated in conjunction with the scanning phase), comb size in range for efficient resource utilization (e.g., range can be estimated in conjunction with the scanning phase). The comb size configuration for the tracking phase may be larger or greater than the comb size configuration for the scanning phase. The total duration configuration for the tracking phase may be larger or greater than the total duration configuration for the scanning phase.
[0085] The resource pool configuration includes separate pools for the scanning phase and the tracking phase, and the association between the pools or resources within the pools may be included in the resource pool configuration. A device (e.g., a base station) providing the resource pool configuration may provide the association between the separate pools to a UE or device performing the scanning phase and the tracking phase. The association may help to correctly estimate the range, velocity, and angle with high resolution and maximum unambiguous range, velocity, and field of view. For example, a scanning phase resource pool may have a comb-4 in the time domain and 0.25 ms per beam (maximum velocity of 75 m / s and velocity resolution of 21 m / s), which is associated with a tracking phase resource pool having a comb-14 in the time domain (symbols per time slot) and 5 ms per beam (maximum velocity of 21 m / s and velocity resolution of 1 m / s). The association of the scanning phase with the tracking phase may together result in a maximum velocity of 75 m / x and a velocity resolution of 21 m / s. For example, Figure 8 Figure 800 provides an example of a scanning phase 802 and a tracking phase 804. The scanning phase 802 may include 9 receive beams (comb-4 in the time and frequency domains) and may be configured to scan 0.25 ms per beam with a 4-symbol interval. The maximum absolute velocity may include 75.1 m / s with a velocity resolution of 21 m / s. The tracking phase 804 may be configured to track at a rate of 5 ms per target / beam with a 14-symbol interval in the frequency domain with comb-4. The maximum absolute velocity may include 21 m / s with a velocity resolution of 1 m / s.
[0086] In some aspects, a resource pool configuration may include multiple resource pools. In such cases, a device (e.g., a UE) may select a resource pool from the multiple resource pools. In some aspects, a device may select an appropriate resource pool in which to transmit based on matching resource or quality of service requirements. In some aspects, when resources are insufficient or in excess of required resources, a device may select a resource pool that may not match or be compatible with the resource or quality of service requirements. For example, narrowband sensing transmission may be performed on a large bandwidth resource pool rather than a small bandwidth resource pool as an exception. If a device measures a CBR-type quantity indicating that its nominal pool is very congested while one or more other pools are not congested, the device may select a different pool. In some cases, there may be restrictions on how often a pool different from the nominal pool may be used (e.g., based on a timer, duty cycle, etc.). In some cases, if a different pool is to be used, the device may attempt to protect "legitimate" UEs by transmitting at a lower power. In some cases, a device may explicitly request permission from the device providing the resource pool configuration (e.g., a base station) to temporarily change the pool with which the device expects resource utilization in the future. In some cases, the device (e.g., base station) providing the resource pool configuration may freely allow the request or may block the request in a semi-static manner. In some cases, if the device (e.g., UE) is able to obtain the desired resources, the device may send an ACK or NACK.
[0087] Figure 9 900 is a call flow diagram of signaling between a UE 902 and a network entity 904. The network entity 904 may include a base station configured to provide at least one cell. The UE 902 may be configured to communicate with the network entity 904. For example, Figure 1 In the context of , network entity 904 may correspond to base station 102, and UE 902 may correspond to at least UE 104. In another example, Figure 3 In the context of , the network entity 904 may correspond to the base station 310 and the UE 902 may correspond to the UE 350.
[0088] At 906, the network entity may output a sensing resource pool configuration to UE 902. UE 902 may receive the sensing resource pool configuration from network entity 904. The UE may receive a sensing resource pool configuration for use of uplink resources for a joint communication and radar system. The sensing resource pool configuration may be based on at least one of a time resource allocation, a space resource allocation, or a frequency resource allocation. In some aspects, the sensing resource pool configuration may include a frequency comb or a time comb. In some aspects, the sensing resource pool configuration may include a time periodicity. In some aspects, the sensing resource pool configuration may include a maximum frame or a maximum bandwidth for sensing operations. In some aspects, the sensing resource pool configuration may include azimuth parameters or elevation parameters for beams used for sensing operations. In some aspects, the sensing resource pool configuration may be based on an expected quality of service level for the sensing resource pool. The expected quality of service may be based on at least one of a supported detection range, a supported speed, or a supported angular direction. The expected quality of service may be based on at least one of an update rate or a latency for performing sensing operations. The expected quality of service may be based on at least one of a detection rate or a priority index.
[0089] At 908, UE 902 may select a first sensing resource pool from the plurality of sensing resource pools. If the sensing resource pool configuration includes a plurality of sensing resource pools, UE 902 may select the first sensing resource pool from the plurality of sensing resource pools. In some aspects, the first sensing resource pool may be selected based on matching resources or expected quality of service. In some aspects, if resources within the first sensing resource pool are insufficient or excessive, the selected first sensing resource pool may not be consistent with the matching resources or expected quality of service.
