Description

[Technical field]

[0001]

[0001] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly to reference signal (RS) operations for unconnected devices. Some embodiments of the present technology described below may enable a user equipment (UE) to use a connected mode RS in an unconnected mode, such as an RRC idle mode or an inactive mode. [Background technology]

[0002]

[0002] Wireless communication networks have been widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, etc. These wireless networks may be multiple access networks capable of supporting multiple users by sharing available network resources. Such networks may be multiple access networks supporting communication for multiple users by sharing available network resources.

[0003]

[0003] A wireless communication network may include several components. These components may include wireless communication devices such as base stations (or Node Bs) that may support communication for several user equipments (UEs). The UEs may communicate with the base stations via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station.

[0004]

[0004] A base station may 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 a base station may encounter interference due to transmissions from neighboring base stations or other wireless radio frequency (RF) transmitters. On the uplink, transmissions from a UE may encounter interference from uplink transmissions from other UEs communicating with neighboring base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and the uplink.

[0005]

[0005] As the demand for mobile broadband access continues to increase, the potential for interference and congested networks increases, more UEs access long-range wireless communication networks, and more short-range wireless systems are deployed within communities. Research and development continues to advance wireless technologies not only to meet the growing demand for mobile broadband access, but also to evolve and improve the user experience of mobile communications.

[0018]

[0031] The Appendices provide further details regarding various aspects of the disclosure, the subject matter therein forming a part of the specification of this application.

[0019]

[0032] Like reference numbers and designations in the various drawings indicate like elements.

[0020]

[0033] The detailed description of the present invention described below with reference to the accompanying drawings and appendix illustrates various configurations and is not intended to limit the scope of the present disclosure. Instead, the detailed description of the present invention includes specific details for the purpose of providing a thorough understanding of the subject matter of the present invention. It will be apparent to those skilled in the art that these specific details are not required in every instance, and that in some instances, well-known structures and components are shown in block diagram form for clarity of presentation.

[0021]

[0034] The present disclosure generally relates to providing or participating in authorized shared access between two or more wireless devices in one or more wireless communication systems, also referred to as wireless communication networks. In various implementations, the techniques and apparatus may be used for 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. The terms "network" and "system" described herein may be used interchangeably.

[0022]

[0035] A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (W-CDMA) and Low Chip Rate (LCR). CDMA2000 covers IS-2000, IS-95, and IS-856 standards.

[0023]

[0036] The TDMA network may implement a radio technology such as, for example, Global System for Mobile Communications (GSM). The 3rd Generation Partnership Project (3GPP) defines standards for the GSM EDGE (enhanced data rates for GSM evolution) radio access network (RAN), also denoted as GERAN. The GERAN is the radio component of GSM / EDGE together with the network that couples the base stations (e.g., Ater and Abis interfaces) and the base station controllers (such as the A interface). The radio access network represents the component of the GSM network through which calls and packet data are routed from the public switched telephone network (PSTN) and the Internet to and from the subscriber handsets, also known as user terminals or user equipment (UE). A mobile phone operator's network may comprise one or more GERANs, which in the case of UMTS / GSM networks may be coupled to a UTRAN. Furthermore, the operator network may also include one or more LTE networks, or one or more other networks. Various different network types may use different radio access technologies (RATs) and RANs.

[0024]

[0037] OFDMA networks may implement radio technologies such as Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, Flash OFDM, etc. UTRA, E-UTRA, and GSM are parts of the Universal Mobile Telecommunications System (UMTS). In particular, Long Term Evolution (LTE) is a release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents from an organization named "3rd Generation Partnership Project" (3GPP), and cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies and standards are known or being developed. For example, 3GPP is a collaboration between groups of telecommunications associations that aims to define globally applicable third generation (3G) mobile phone specifications. 3GPP LTE is a 3GPP project that aims to improve the UMTS mobile phone standard. 3GPP may define specifications for next generation mobile networks, mobile systems, and mobile devices. While this disclosure may describe some aspects with reference to LTE, 4G, or 5G NR technology, it will be understood that this specification is not intended to be limited to a particular technology or application, and one or more aspects described with respect to one technology may be applicable to another technology. Additionally, one or more aspects of the present disclosure may relate to shared access to a wireless spectrum between networks using different radio access technologies or radio air interfaces.

[0025]

[0038] 5G networks contemplate diverse deployments, diverse spectrum, and diverse services and devices that may be implemented using an OFDM-based unified air interface. To achieve these goals, further enhancements to LTE and LTE-A are considered in addition to the development of new radio technologies for 5G NR networks. 5G NR is a service that supports: (1) ultra-high density (e.g., approximately 1M nodes / km);2 (2) for the mass Internet of Things (IoT) with ultra-low complexity (e.g., on the order of 10 bits / second), ultra-low energy (e.g., on the order of 10+ years battery life), and deep coverage with the ability to reach difficult locations; (3) for mission-critical control, including IoT, with strong security to protect sensitive personal, financial, or confidential information, ultra-high reliability (e.g., on the order of 99.9999% reliability), ultra-low latency (e.g., on the order of 1 millisecond (ms)), and users with or without widespread mobility; and (4) for ultra-high capacity (e.g., on the order of 10 Tbps / km 2 ), scaling to provide coverage with enhanced mobile broadband including extreme data rates (e.g., multi-Gbps rates, 100+ Mbps user experience rates), and deep awareness with advanced discovery and optimization.

[0026]

[0039] Devices, networks, and systems may be configured to communicate over one or more portions of the electromagnetic spectrum. The electromagnetic spectrum is often subdivided into various classes, bands, channels, etc., based on frequency or wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although portions of FR1 are 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 arises with respect to FR2, which is often referred to (interchangeably) as the "millimeter wave" (mmWave) band in documents and articles, even though it is distinct from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified by the International Telecommunications Union (ITU) as the "mmWave" band.

[0027]

[0040] With the above aspects in mind, it should be understood that unless otherwise specified, terms such as "sub-6 GHz," as used herein, may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, it should be understood that unless otherwise specified, terms such as "mmWave," as used herein, may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

[0028]

[0041] 5G NR devices, networks, and systems may be implemented to use optimized OFDM-based waveform features. These features may include scalable numerology and transmission time intervals (TTIs), a common flexible framework for efficient multiplexing of services and features in dynamic, low-latency time division duplex (TDD) or frequency division duplex (FDD) designs, and advanced wireless technologies such as massive multiple-input multiple-output (MIMO), robust mmWave transmission, advanced channel coding, and device-centric mobility. The scalability of numerology in 5G NR with the scaling of subcarrier spacing may efficiently address operating diverse services across diverse spectrum and diverse deployments. For example, in various outdoor and macro coverage deployments of FDD or TDD implementations below 3 GHz, subcarrier spacing with 15 kHz may occur over bandwidths of, for example, 1, 5, 10, 20 MHz, etc. In various other outdoor and small cell coverage deployments of TDD over 3 GHz, subcarrier spacing with 30 kHz may occur over 80 / 100 MHz bandwidths. In various other indoor wideband implementations using TDD over the unlicensed portion of the 5 GHz band, subcarrier spacing may occur at 60 kHz over a 160 MHz bandwidth. Finally, in various deployments transmitting with mmWave components at 28 GHz TDD, subcarrier spacing may occur at 120 kHz over a 500 MHz bandwidth.

[0029]

[0042] 5G NR's scalable numerology 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, and longer TTIs can be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmissions to start on symbol boundaries. 5G NR also contemplates a self-contained integrated subframe design with uplink or downlink scheduling information, data, and acknowledgments in the same subframe. The self-contained integrated subframe supports communication in unlicensed or contention-based shared spectrum, an adaptive uplink or downlink that can be flexibly configured per cell to dynamically switch between uplink and downlink to meet current traffic needs.

[0030]

[0043] For clarity, certain aspects of the apparatus and techniques may be described below with reference to an example 5G NR implementation or in a 5G-centric manner, and 5G terminology may be used as an illustrative example in parts of the description below, but the description is not intended to be limited to 5G applications.

[0031]

[0044] Furthermore, it should be understood that in operation, a wireless communications network adapted in accordance with the concepts herein may operate in any combination of licensed or unlicensed spectrum, depending on loading and availability. Thus, it will be apparent to those skilled in the art that the systems, apparatus, and methods described herein may be applied to other communications systems and applications beyond the specific examples provided.

[0032]

[0045] Although aspects and implementations are described in this application by way of illustration to some examples, those skilled in the art will understand that additional implementations and use cases may occur in many different configurations and scenarios. The innovations described herein may be implemented across many different platform types, devices, systems, shapes, sizes, packaging configurations. For example, implementations or uses may occur via integrated chip implementations or other non-modular component-based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail or purchasing devices, medical devices, AI-enabled devices, etc.). Although some examples may or may not be specifically targeted to a use case or application, there may be a wide variety of applicability of the described innovations. Implementations may range from chip-level or modular components to non-modular, non-chip-level implementations, and even aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more described aspects. In some practical settings, devices incorporating the described aspects and features may also include additional components and features necessarily for the implementation and practice of the claimed and described aspects. It is contemplated that the innovations described herein may be practiced in a wide variety of implementations, including both large and small devices of various sizes, shapes, and configurations, chip-level components, multi-component systems (e.g., radio frequency (RF) chains, communication interfaces, processors), distributed configurations, end-user devices, and the like.

[0033]

[0046] 1 is a block diagram illustrating details of an exemplary wireless communication system according to one or more aspects. The wireless communication system may include a wireless network 100. The wireless network 100 may include, for example, a 5G wireless network. As will be appreciated by one skilled in the art, the components appearing in FIG. 1 may have related counterparts in other network configurations, including, for example, cellular-style network configurations and non-cellular-style network configurations (e.g., device-to-device or peer-to-peer or ad-hoc network configurations, etc.).

[0034]

[0047] The wireless network 100 illustrated in FIG. 1 includes several base stations 105 and other network entities. A base station may be a station that communicates with UEs and may also be referred to as an evolved Node B (eNB), next generation eNB (gNB), access point, etc. Each base station 105 may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to this particular geographic coverage area of ​​a base station or a base station subsystem serving the coverage area depending on the context in which the term is used. In implementations of the wireless network 100 herein, the base stations 105 may be associated with the same operator or different operators (e.g., the wireless network 100 may include a multi-operator wireless network). Furthermore, in implementations of the wireless network 100 herein, the base station 105 may provide wireless communications using one or more of the same frequencies as neighboring cells (e.g., one or more frequency bands in a licensed spectrum, an unlicensed spectrum, or a combination thereof). In some examples, an individual 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.

[0035]

[0048] A base station may provide communication coverage for a macro cell, or a small cell such as a pico cell or femto cell, or other type of cell. A macro cell generally covers a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs having a service subscription with a network provider. A small cell such as a pico cell generally covers a relatively smaller geographic area and may allow unrestricted access by UEs having a service subscription with a network provider. A small cell such as a femto cell will generally also cover a relatively small geographic area (e.g., a home) and may provide unrestricted access as well as restricted access by UEs having an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in the 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, a pico base station, a femto base station, or a home base station. In the example shown in FIG. 1, base stations 105d and 105e are regular macro base stations, while base stations 105a-105c are macro base stations enabled with one of three-dimensional (3D), full-dimensional (FD), or massive MIMO. Base stations 105a-105c utilize their higher-dimensional MIMO capabilities to increase coverage and capacity by leveraging 3D beamforming in both elevation and azimuth beamforming. Base station 105f is a small cell base station, which may be a home node or a portable access point. A base station may support one or multiple (e.g., two, three, four, etc.) cells.

[0036]

[0049] The wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations may have similar frame timing and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, the base stations may have different frame timing and transmissions from different base stations may not be aligned in time. In some scenarios, the network may be enabled or configured to handle dynamic switching between synchronous and asynchronous operation.

[0037]

[0050] The UEs 115 are dispersed throughout the wireless network 100, and each UE may be fixed or mobile. Although a mobile device is typically referred to as a UE in standards and specifications promulgated by 3GPP, it should be appreciated that such a device may additionally or otherwise be referred to by those skilled in the art as a mobile station (MS), subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal (AT), mobile terminal, wireless terminal, remote terminal, handset, terminal, user agent, mobile client, client, gaming device, augmented reality device, vehicle component, vehicle device, or vehicle module, or some other suitable terminology. Within this document, a "mobile" device or UE does not necessarily have to be capable of movement and may be stationary. Some non-limiting examples of mobile devices that may include one or more implementations of UE 115 include mobiles, cellular (cell) phones, smartphones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, and personal digital assistants (PDAs).The mobile device may also be an IoT device or "Internet of Everything" (IoE) device, such as an automobile or other transportation vehicle, a satellite radio, a Global Navigation Satellite System (GNSS) device, a logistics controller, a drone, a multicopter, a quadcopter, a smart energy or security device, a solar panel or solar array, city lighting, water, or other infrastructure; an industrial automation and enterprise device; a consumer and wearable device, such as eyewear, a wearable camera, a smart watch, a health or fitness tracker, a mammalian implant device, a gesture tracking device, a medical device, a digital audio player (e.g., MP3 player), a camera, a game console; a digital home device or a smart home device, such as a home audio, video, and multimedia device, an appliance, a sensor, a vending machine, an intelligent lighting, a home security system, a smart meter, etc. In one aspect, the UE may be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, the UE may be a device that does not include a UICC. In some aspects, a UE that does not include a UICC may be referred to as an IoE device. 1 are examples of mobile smartphone type devices accessing the wireless network 100. The UEs 115a-115d of the implementation shown in FIG. 1 are examples of various machines configured for connection communications, including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. The UEs 115e-115k shown in FIG. 1 are examples of various machines configured for communications accessing the wireless network 100.

[0038]

[0051] A mobile device, such as the UE 115, may be capable of communicating with any type of base station, whether a macro base station, a pico base station, a femto base station, a relay, etc. In FIG. 1, the communication links (represented as lightning bolts) indicate wireless transmissions between the UE and a serving base station, which is a base station designated to serve the UE on the downlink or uplink, or desired transmissions between base stations, and backhaul transmissions 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 may be performed using wired or wireless communication links.

[0039]

[0052] During operation in the wireless network 100, the base stations 105a-105c serve the UEs 115a and 115b using 3D beamforming and coordinated spatial techniques such as coordinated multipoint (CoMP) or multi-connectivity. The macro base station 105d performs backhaul communications with the base stations 105a-105c, as well as the small cell, base station 105f. The macro base station 105d also transmits multicast services to which the UEs 115c and 115d subscribe and are received. Such multicast services may include mobile television or stream video, or may include other services for providing community information, such as weather emergencies, or alerts such as amber or grey alerts.

[0040]

[0053] The wireless network 100 of the implementation supports mission-critical communications with ultra-reliable and redundant links for mission-critical devices such as drone UE 115e. Redundant communication links with UE 115e include from macro base stations 105d and 105e and small cell base station 105f. Other machine-type devices such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device) may communicate through wireless network 100 directly with base stations such as small cell base station 105f and macro base station 105e, or in a multi-hop configuration by communicating with another user device that relays its information to the network, e.g., UE 115f communicating temperature measurement information to smart meter UE 115g, which is then reported to the network through small cell base station 105f. The wireless network 100 may also provide additional network efficiency through dynamic low latency TDD or low latency FDD communications, such as in a vehicle-to-vehicle (V2V) mesh network between UEs 115i-115k communicating with the macro base station 105e.

[0041]

[0054] FIG. 2 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 may be any of the base stations and one of the UEs of FIG. 1. In the case of a restricted association scenario (described above), the base station 105 may be the small cell base station 105f of FIG. 1, and the UE 115 may be a UE 115c or 115d operating within the coverage area of ​​the base station 105f that is included in the list of accessible UEs of the small cell base station 105f to access the small cell base station 105f. The base station 105 may also be some other type of base station. As shown in FIG. 2, to facilitate wireless communication, the base station 105 may be equipped with antennas 234a-234t, and the UE 115 may be equipped with antennas 252a-252r.

[0042]

[0055] In the base station 105, the transmit processor 220 may receive data from the data source 212 and control information from a controller 240, such as a processor. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid automatic repeat request (ARQ) indicator channel (PHICH), a physical downlink control channel (PDCCH), an enhanced physical downlink control channel (EPDCCH), an MTC physical downlink control channel (MPDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. In addition, the transmit processor 220 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols, for example, for a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), and a cell-specific reference signal. The transmit (TX) MIMO processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, or reference symbols, if applicable, and may provide output symbol streams to the modulators (MODs) 232a-t. For example, the spatial processing performed on the data symbols, control symbols, or reference symbols may include precoding. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may additionally or alternatively process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators 232a-t may be transmitted via the antennas 234a-t, respectively.

[0043]

[0056] At the UE 115, the antennas 252a-252r may receive downlink signals from the base station 105 and may provide received signals to demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the demodulators 254a-254r, perform MIMO detection on the received symbols, if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols and provide decoded data for the UE 115 to a data sink 260 and provide decoded control information to a controller 280, such as a processor.

[0044]

[0057] On the uplink, at the UE 115, the transmit processor 264 may receive and process data from a data source 262 (e.g., in a physical uplink shared channel (PUSCH)) and receive control information from a controller 280 (e.g., in a physical uplink control channel (PUCCH)). Additionally, the transmit processor 264 may also generate reference symbols for a reference signal. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a-254r (e.g., for SC-FDM, etc.), and transmitted to the base station 105. At the base station 105, uplink signals from the UE 115 may be received by antennas 234, processed by a demodulator 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 115. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to a controller 240 .

[0045]

[0058] The controllers 240 and 280 may direct operation at the base station 105 and the UE 115, respectively. The controller 240 or other processors and modules at the base station 105 or the controller 280 or other processors and modules at the UE 115 may perform or direct the execution of various processes of the techniques described herein, such as for performing or directing the execution shown in FIGS. 5-7, 13, and 14, or other processes of the techniques described herein. The memories 242 and 282 may store data and program codes for the base station 105 and the UE 115, respectively. The scheduler 244 may schedule the UE for data transmission on the downlink or uplink.

[0046]

[0059] In some cases, the UE 115 and the base station 105 may operate in a shared radio frequency spectrum band, which may include licensed or unlicensed (e.g., contention-based) frequency spectrum. In the unlicensed frequency portion of the shared radio frequency spectrum band, the UE 115 or the base station 105 may traditionally perform a medium sensing procedure to contend for access to the frequency spectrum. For example, the UE 115 or the base station 105 may perform a listen-before-talk or listen-before-transmitting (LBT) procedure, such as clear channel assessment (CCA), before communicating to determine if a shared channel is available. In some implementations, the CCA may include an energy detection procedure to determine if there is any other active transmission. For example, the device may infer that a change in a received signal strength indicator (RSSI) of a power meter indicates that the channel is occupied. In particular, a signal power centered in a certain bandwidth and above a predetermined noise floor may indicate another wireless transmitter. CCA may also include detection of a particular sequence that indicates use of the channel. For example, another device may transmit a particular preamble before transmitting a data sequence. In some cases, the LBT procedure may involve a wireless node adjusting its own backoff window based on the amount of energy detected on the channel or acknowledgment / negative acknowledgment (ACK / NACK) feedback for its own transmitted packets as a proxy for collisions.

[0047]

[0060] In 5G NR operation in Release 17, it is proposed to use a Tracking Reference Signal (TRS) or Channel State Information Reference Signal (CSI-RS) already configured for connected mode UEs for idle or inactive mode UEs. The use of TRS or CSI-RS for non-connected mode UEs, such as idle and inactive mode UEs, may enable the UEs to help receive pages. Such reference signals, like paging messages, are transmitted on multiple synchronization signal block (SSB) beams.

[0048]

[0061] A connected mode UE typically uses narrower beams than SSB beams, and the RS may not be Quasi-Colocated (QCL) with all SSBs transmitted in the cell. It has also been proposed not to have blind detection of the RS by a non-connected mode UE for tracking loop updates.

[0049]

[0062] In some implementations, the network provides both configuration parameters and lifetime / availability of the RS. Due to the periodic behavior (paging scheme) of unconnected UEs, the periodic RS allows for extended paging reception.

[0050]

[0063] Additionally or alternatively, aperiodic RS may be used, which may be more useful for transient behavior, e.g., for UEs being paged by paging indications (PIs), etc. In addition to or as an alternative to CSI-RS and TRS reference signals, dedicated RSs (e.g., UE-specific RSs or non-connected mode specific RSs) may be used as reference signals to help receive paging messages.

[0051]

[0064] FIG. 3 shows example information elements for CSI-RS related information elements (IEs). In FIG. 3, CSI-RS reporting configuration IEs and measurement configurations are shown. Such information elements may be used to report CSI-RS measurement information that may be determined based on the CSI-RS, such as a tracking reference signal (TRS). A TRS is a special case of a CSI-RS.

[0052]

[0065] FIG. 4 illustrates an example of a wireless communication system 400 supporting an extended non-connected mode operation according to aspects of the disclosure. In some examples, the wireless communication system 400 may implement aspects of the wireless communication system 100. For example, the wireless communication system 400 may include multiple wireless communication devices and possibly network entities. In the example of FIG. 4, the wireless communication system 400 includes a base station 105, a UE 115, and possibly a second UE 405. The extended non-connected mode operation may include the use of a connected mode RS that was initially configured in the connected mode UE in the non-connected mode. The use of the connected mode RS in the non-connected mode may reduce latency and increase throughput by increasing the effectiveness of paging messages. Thus, network and device performance may be improved.

[0053]

[0066] The UE 115 and the base station 105 may be configured to communicate over a frequency band, such as FR1 having frequencies between 410 and 7125 MHz, FR2 having frequencies between 24250 and 52600 MHz for mm-wave, and / or one or more other frequency bands. Note that the subcarrier spacing (SCS) may be equal to 15, 30, 60, or 120 kHz for some data channels. The UE 115 and the base station 105 may be configured to communicate over one or more component carriers (CCs), such as a representative first CC 481, a second CC 482, a third CC 483, and a fourth CC 484. Although four CCs are shown, this is for illustrative purposes only, and more or less than four CCs may be used. The one or more CCs may be used to communicate control channel transmissions, data channel transmissions, and / or sidelink channel transmissions.

[0054]

[0067] Such transmissions may include a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), a physical sidelink control channel (PSCCH), a physical sidelink shared channel (PSSCH), or a physical sidelink feedback channel (PSFCH). Such transmissions may be scheduled by aperiodic grants and / or periodic grants.

[0055]

[0068] Each periodic grant may have a corresponding configuration, such as configuration parameters / settings. A periodic grant configuration may include a configured grant (CG) configuration and settings. Additionally or alternatively, one or more periodic grants (e.g., their CGs) may have or be assigned a CC ID, such as an intended CC ID.

[0056]

[0069] Each CC may have a corresponding configuration, such as configuration parameters / settings. The configuration may include bandwidth, bandwidth portion, HARQ process, TCI state, RS, control channel resource, data channel resource, or a combination thereof. Additionally or alternatively, one or more CCs may have or be assigned a cell ID, a bandwidth portion (BWP) ID, or both. The cell ID may include a unique cell ID for the CC, a virtual cell ID, or a specific cell ID of a specific CC among the multiple CCs. Additionally or alternatively, one or more CCs may have or be assigned a HARQ ID. Each CC may also have a corresponding management function, such as beam management, BWP switching function, or both. In some implementations, two or more CCs are quasi-colocated such that the CCs have the same beam and / or the same symbols.

[0057]

[0070] In some implementations, the control information may be communicated via the UE 115 and the base station 105. For example, the control information may be communicated using a MAC-CE transmission, an RRC transmission, a SCI (sidelink control information), transmission, another transmission, or a combination thereof.

[0058]

[0071] The UE 115, and possibly the second UE 405, may include various components (e.g., structural components, hardware components) used to perform one or more functions described herein. For example, these components may include a processor 402, a memory 404, a transmitter 410, a receiver 412, an encoder 413, a decoder 414, a connected mode manager 415, a non-connected mode manager 416, and antennas 252a-r. The processor 402 may be configured to execute instructions stored in the memory 404 to perform operations described herein. In some implementations, the processor 402 includes or corresponds to a controller / processor 280, and the memory 404 includes or corresponds to a memory 282. The memory 404 may also be configured to store RS configuration data 406, RS resource data 408, connected mode settings data 442, non-connected mode data 444, or combinations thereof, as further described herein.

[0059]

[0072] The RS configuration data 406 includes or corresponds to data associated with or corresponding to a configuration for RS transmission. For example, the RS configuration data 406 may indicate one or more settings and / or parameters for RS transmission and feedback. Such settings and / or parameters for RS transmission and feedback may include SCS parameters, bandwidth parameters, QCL parameters, duration parameters, subset parameters, or combinations thereof, for one or more configured RSs. The RS resource data 408 includes or corresponds to data indicating or corresponding to transmission resources for RS transmission and RS feedback.

[0060]

[0073] The connected mode settings data 442 includes or corresponds to data related to non-connected mode operation. The connected mode settings data 442 may include settings and / or condition data for RS transmit and RS report operations when in connected mode.

[0061]

[0074] The non-connected mode settings data 444 includes or corresponds to data related to non-connected mode operation. The non-connected mode settings data 444 may include settings and / or condition data for RS transmit and RS report operations when in the non-connected mode.

[0062]

[0075] The transmitter 410 is configured to transmit data to one or more other devices, and the receiver 412 is configured to receive data from one or more other devices. For example, the transmitter 410 may transmit data, and the receiver 412 may receive data, via a network, such as a wired network, a wireless network, or a combination thereof. For example, the UE 115 may be configured to transmit and / or receive data via a direct device-to-device connection, a local area network (LAN), a wide area network (WAN), a modem-to-modem connection, the Internet, an intranet, an extranet, a cable transmission system, a cellular communication network, any combination of the above, or any other communication network now known or later developed that enables two or more electronic devices to communicate. In some implementations, the transmitter 410 and the receiver 412 may be replaced by a transceiver. Additionally or alternatively, the transmitter 410, the receiver 412, or both may include or correspond to one or more components of the UE 115 described with reference to FIG. 2.

[0063]

[0076] The encoder 413 and the decoder 414 may be configured to encode and decode data for transmission. The connected mode manager 415 may be configured to determine a connected mode operation and perform the operation. For example, the connected mode manager 415 is configured to determine which one or more resources to use for RS transmission and RS feedback when operating in a connected mode, such as when and where to perform reference signal transmission and feedback transmission therefor. As another example, the connected mode manager 415 is configured to perform time and frequency tracking operations and measurement operations on RS transmission.

[0064]

[0077] The non-connected mode manager 416 may be configured to determine and perform connected mode operations. For example, the non-connected mode manager 416 is configured to determine which one or more resources to use for RS transmission and RS feedback when operating in a non-connected mode, such as when and where to perform reference signal transmission and feedback transmission therefor. As another example, the non-connected mode manager 416 is configured to perform time and frequency tracking and measurement operations on RS transmissions.

[0065]

[0078] The base station 105 includes a processor 430, a memory 432, a transmitter 434, a receiver 436, an encoder 437, a decoder 438, a connected mode manager 439, a non-connected mode manager 440, and antennas 234a-t. The processor 430 may be configured to execute instructions stored in the memory 432 to perform operations described herein. In some implementations, the processor 430 includes or corresponds to the controller / processor 240, and the memory 432 includes or corresponds to the memory 242. The memory 432, like the UE 115, may be configured to store RS configuration data 406, RS resource data 408, connected mode settings data 442, non-connected mode data 444, or a combination thereof, as further described herein.

[0066]

[0079] The transmitter 434 is configured to transmit data to one or more other devices, and the receiver 436 is configured to receive data from one or more other devices. For example, the transmitter 434 may transmit data, and the receiver 436 may receive data, via a network, such as a wired network, a wireless network, or a combination thereof. For example, the base station 105 may be configured to transmit and / or receive data via a direct device-to-device connection, a local area network (LAN), a wide area network (WAN), a modem-to-modem connection, the Internet, an intranet, an extranet, a cable transmission system, a cellular communication network, any combination of the above, or any other communication network now known or later developed that enables two or more electronic devices to communicate. In some implementations, the transmitter 434 and the receiver 436 may be replaced by a transceiver. Additionally or alternatively, the transmitter 434, the receiver 436, or both may include or correspond to one or more components of the base station 105 described with reference to FIG. 2.

[0067]

[0080] The encoder 437 and the decoder 438 may include the same functionality as described with reference to the encoder 413 and the decoder 414, respectively. The connected mode manager 439 may include similar functionality as described with reference to the connected mode manager 415. The unconnected mode manager 440 may include similar functionality as described with reference to the unconnected mode manager 416.

[0068]

[0081] During operation of the wireless communication system 400, the base station 105 may determine that the UE 115 has extended non-connected mode capabilities. For example, the base station 105 may transmit a message 448 including an extended RS operation indicator 490 (e.g., connected mode RS configuration for non-connected mode operation). The indicator 490 may indicate the extended RS operation capability for the non-connected mode, or a particular type or mode of RS operation for the non-connected mode. In some implementations, the base station 105 sends control information to indicate to the UE 115 that the extended RS operation for the non-connected mode, and / or a particular type of extended RS operation for the non-connected mode should be used. For example, in some implementations, the message 448 (or another message, such as a configuration transmission 450) is transmitted by the base station 105 or the network entity 405. The configuration transmission 450 may include or indicate using the extended RS operation for the non-connected mode, or adjusting or implementing a setting value of a particular type of extended RS operation for the non-connected mode. For example, the configuration transmission 450 may include 444, 442, or both shown in the example of FIG.

[0069]

[0082] In operation, the devices of the wireless communication system 400 perform enhanced RS operations for a non-connected mode. For example, the wireless communication devices (e.g., base stations and UEs) exchange transmissions over downlink or uplink channels. In the example of FIG. 4, the base station 105 possibly transmits an RS configuration message 452 to the UE 115. The RS configuration message 452 may include or indicate a particular RS configuration for operation in a connected mode, a non-connected mode, or both.

[0070]

[0083] The UE 115 may receive the RS configuration message 452 and may determine a particular configuration of the RS indicated by the base station 105. The UE 115 may possibly determine particular resources reserved by the base station 105 for RS transmission. The UE 115 may then monitor RS transmissions, such as RS transmission 454, while in an unconnected mode based on the RS configuration message 452. For example, the base station 105 may transmit the RS transmission 454 to the UE 115 and possibly one or more other devices.

[0071]

[0084] The UE 115 monitors the RS transmissions 454 while in the disconnected mode based on the RS configuration and possibly one or more set values. The UE 115 may perform one or more actions based on the RS transmissions 454 to select transmit and / or receive parameters for future operation.

[0072]

[0085] 4, the base station 105 transmits a paging message 456 after the RS transmission 454. The paging message 456 may include or correspond to a paging indication or a wake-up message. The paging message 456 may indicate that the base station 105 has data for the UE, and the paging message 456 may enable the UE 115 to switch from a non-connected mode to a connected mode.

[0073]

[0086] Once in the connected mode, the UE 115 and the base station 105 may exchange communications. For example, the base station 105 may potentially send downlink transmissions 458 to the UE 115.

[0074]

[0087] Thus, the UE 115 and base station 105 may be able to perform RS operations more effectively, i.e., reusing connected mode RS signals for non-connected mode UEs or receiving dedicated RS for non-connected mode UEs. Thus, FIG. 4 describes enhanced RS operations for non-connected mode devices. Using enhanced RS operations may enable improvements and reduce network overhead when devices are operating in non-connected modes, such as idle or inactive modes. Performing enhanced RS operations for non-connected mode allows for increased success of paging message reception, thus enabling enhanced UE and network performance by increasing throughput and reducing errors and latency.

[0075]

[0088] UEs 5-7 illustrate an example ladder diagram of RS operation for a UE in a non-connected mode, according to some aspects. Referring to FIG. 5, FIG. 5 is a ladder diagram 500 of RS operation for a UE in a non-connected mode, according to some aspects. In the example of FIG. 5, the ladder diagram illustrates a UE 115 and a network entity, such as a base station 105, where the UE was already connected to the network entity.

[0076]

[0089] At 510, the UE 115 operates in a connected mode with the base station 105 (e.g., a gNB). For example, the UE 115 is in an RRC connected mode with the base station 105. The UE 115 may transmit and receive data to and from the base station 105 while in the connected mode. In some such implementations, the UE 115 may be configured with one or more RSs and may receive RSs from the base station 105 in the connected mode.

[0077]

[0090] At 515, the base station 105 transmits an RRC release message to the UE 115, the RRC release message including or indicating the RS configuration. For example, the base station 105 generates an RRC release message with RS availability information and transmits it to the UE 115. The RS availability information may include or indicate an RS configuration that the UE 115 should use while in the unconnected mode. The RRC release message is configured to transition the UE 115 from a connected mode to an unconnected mode, such as an idle mode or an inactive mode. The RS configuration information may include settings, formats, transmission resources, etc. for the RS.

[0078]

[0091] At 520, the UE 115 operates in a non-connected mode. For example, the UE 115 switches from a connected mode to an idle mode or an inactive mode in response to an RRC release message.

[0079]

[0092] At 525, the UE 115 determines an RS configuration for the non-connected mode based on the RS information. For example, the UE 115 determines an RS configuration for connected mode RSs to use while in the non-connected mode based on the RS availability information included in the RRC release message.

[0080]

[0093] At 530, the base station 105 transmits an RS to the UE 115. For example, the base station 105 generates an RS transmission and transmits it to the UE 115 for time and frequency tracking and measurement operations. The RS may include a CSI-RS, a TRS, or a dedicated RS. In some implementations, the RS is sent to multiple devices, such as multiple UEs. In other implementations, the RS is sent to a single device.

[0081]

[0094] At 535, the base station 105 transmits a paging message to the UE 115. For example, the base station 105 generates a paging message and transmits it to the UE 115, and the UE 115 receives the paging message based on the RS transmission. To illustrate, the UE 115 may determine the best beam or setting to use to monitor and receive the paging message based on the reference signal. The paging message may include or correspond to a wake-up message.

[0082]

[0095] At 540, the base station 105 and the UE 115 perform RRC operations. For example, the base station 105 and the UE 115 exchange RRC messages to switch the UE 115 from a non-connected mode to a connected mode.

[0083]

[0096] At 545, the UE 115 operates in a connected mode with the base station 105. For example, the UE 115 switches from an idle mode or an inactive mode to an RRC connected mode with the base station 105. The UE 115 may transmit and receive data to and from the base station 105 while in the connected mode. In some such implementations, the UE 115 may be configured with one or more RSs and may receive RSs from the base station 105 in the connected mode. The one or more RSs and their corresponding configurations may be the same one or more RSs used by a UE in a non-connected mode.

[0084]

[0097] Thus, in the example of Figure 5, the UE performs RS operation in non-connected mode based on configuration information received from the network entity while in connected mode, i.e., the UE receives the RS configuration in the RRC release message and uses the RS configuration to receive connected mode RS while in non-connected mode.

[0085]

[0098] Referring to Figure 6, Figure 6 is a ladder diagram 600 of RS operation for a UE in a non-connected mode, according to some aspects. In the example of Figure 6, the ladder diagram shows a UE 115 and a network entity, such as a base station 105, where the UE was already connected to the network entity. Compared to the example of Figure 5, in the example of Figure 6, the RS configuration or an indication thereof may be received in a message separate from the RRC release message.

[0086]

[0099] At 610, the UE 115 operates in a connected mode with the base station 105 (e.g., a gNB). For example, the UE 115 is in an RRC connected mode with the base station 105. The UE 115 may transmit and receive data to and from the base station 105 while in the connected mode. In some such implementations, the UE 115 may be configured with one or more RSs and may receive RSs from the base station 105 in the connected mode.

[0087]

[0100] At 615, the base station 105 transmits RS configuration information to the UE 115. For example, the base station 105 generates a message with RS availability information and transmits it to the UE 115. The RS availability information may include or indicate an RS configuration that the UE 115 should use while in a connected mode, a non-connected mode, or both.

[0088]

[0101] At 620, the UE 115 determines an RS configuration for the non-connected mode based on the RS information. For example, the UE 115 determines an RS configuration for connected mode RSs to use while in the non-connected mode based on the RS availability information.

[0089]

[0102] At 625, the base station 105 transmits an RRC release message to the UE 115. For example, the base station 105 generates and transmits an RRC release message configured to transition the UE 115 from a connected mode to an unconnected mode, such as an idle mode or an inactive mode.

[0090]

[0103] At 630, the UE 115 operates in a non-connected mode. For example, the UE 115 switches from a connected mode to an idle mode or an inactive mode in response to an RRC release message.

[0091]

[0104] At 635, the base station 105 transmits an RS to the UE 115. For example, the base station 105 generates an RS transmission and transmits it to the UE 115 for time and frequency tracking and measurement operations. The RS may include a CSI-RS, a TRS, or a dedicated RS. In some implementations, the RS is sent to multiple devices, such as multiple UEs. In other implementations, the RS is sent to a single device.

[0092]

[0105] At 640, the base station 105 transmits a paging message to the UE 115. For example, the base station 105 generates a paging message and transmits it to the UE 115, and the UE 115 receives the paging message based on the RS transmission. To illustrate, the UE 115 may determine the best beam or setting to use to monitor and receive the paging message based on the reference signal. The paging message may include or correspond to a wake-up message.

[0093]

[0106] At 645, the base station 105 and the UE 115 perform RRC operations. For example, the base station 105 and the UE 115 exchange RRC messages to switch the UE 115 from a non-connected mode to a connected mode.

[0094]

[0107] At 650, the UE 115 operates in a connected mode with the base station 105. For example, the UE 115 switches from an idle mode or an inactive mode to an RRC connected mode with the base station 105. The UE 115 may transmit and receive data to and from the base station 105 while in the connected mode. In some such implementations, the UE 115 may be configured with one or more RSs and may receive RSs from the base station 105 in the connected mode. The one or more RSs and their corresponding configurations may be the same one or more RSs used by a UE in a non-connected mode.

[0095]

[0108] Thus, in the example of Figure 6, the UE performs RS operation in non-connected mode based on configuration information received from the network entity while in connected mode, i.e., the UE receives the RS configuration and uses the RS configuration to receive connected mode RS while in non-connected mode.

[0096]

[0109] Referring to Figure 7, Figure 7 is a ladder diagram 700 of RS operation for a UE in a non-connected mode, according to some aspects. In the example of Figure 7, the ladder diagram illustrates multiple UEs, such as a first UE 115a and a second UE 115b, and a network entity, such as a base station 105, where at least one UE was not previously connected to the network entity. Compared to the examples of Figures 5 and 6, the RS configuration or an indication thereof may be received in a broadcast message by a UE that is not connected to the network entity.

[0097]

[0110] At 710, the first UE 115a operates in an unconnected mode. For example, the first UE 115a is in an idle mode or an inactive mode. While in the unconnected mode, the first UE 115a may attempt to monitor reference signals from one or more cells, such as the base station 105.

[0098]

[0111] At 715, the second UE 115b operates in a connected mode with the base station 105 (e.g., a gNB). For example, the second UE 115b is in an RRC connected mode with the base station 105. The second UE 115b may transmit and receive data to and from the base station 105 while in the connected mode. In some such implementations, the second UE 115b may be configured with one or more RSs and may receive RSs from the base station 105 in the connected mode.

[0099]

[0112] At 720, the base station 105 broadcasts RS configuration information to the UEs 115a and 115b. For example, the base station 105 generates a broadcast message with RS availability information and transmits it to the UEs 115a and 115b. The RS availability information may include or indicate the RS configuration that the UEs 115a and 115b should use while in a connected mode, a non-connected mode, or both.

[0100]

[0113] At 725, the first UE 115a determines an RS configuration for the non-connected mode based on the RS configuration information. For example, the first UE 115a determines an RS configuration for connected mode RSs to use while in the non-connected mode based on the RS availability information.

[0101]

[0114] At 730, the second UE 115b determines an RS configuration for the connected mode based on the RS configuration information. For example, the second UE 115b determines an RS configuration for the connected mode RS to use while in the connected mode based on the RS availability information.

[0102]

[0115] The RS configuration information in FIG. 4-FIG. 7 may optionally or additionally indicate which particular RS is available for a UE in non-connected mode if multiple RS resources were configured for the UE while in connected mode. For example, a particular RS may be indicated (e.g., signaled) or a particular RS may be determined based on one or more parameters or conditions. For illustration, a device may determine a particular RS or a subset of RSs to use from multiple RSs based on the RS resource with the smallest ID, the number N of RS resources with the N smallest IDs, all configured RS resources, etc. As another example of indication / signaling, a network may indicate a particular RS or a subset of RSs based on a list of IDs for configured RSs. This indication may be in an RRC message (e.g., an RRC release message) or another message. This indication may be sent with the RS configuration information (e.g., the first RS configuration information) or may be indicated by additional RS configuration information (e.g., the first RS configuration information). The indication information may include a resource set ID or a resource ID associated with the RS resource.

[0103]

[0116] Additionally or alternatively, the RS configuration information of Figures 4-7 may further indicate an expiration time at which the UE may assume that the RS is available when the UE enters a disconnected mode. The expiration time may be indicated in units of seconds (e.g., milliseconds or microseconds), slots, radio frames, paging cycles, etc. Alternatively, the expiration time may be indicated as 0 or null, which may configure the RS to have infinite duration or to have no expiration time.

[0104]

[0117] At 735, the base station 105 transmits an RS to the UEs 115a and 115b. For example, the base station 105 generates an RS transmission and transmits it to the UEs 115a and 115b for time and frequency tracking and measurement operations. The RS may include a CSI-RS, a TRS, or a dedicated RS.

[0105]

[0118] At 740, the second UE 115b uses the RS transmission. For example, the second UE 115b performs a measurement operation on the RS and / or compares a reference signal to a stored signal, and transmits or receives data based on the RS and such operation.

[0106]

[0119] At 745, the base station 105 transmits a paging message to the first UE 115a. For example, the base station 105 generates a paging message and transmits it to the first UE 115a, and the first UE 115a receives the paging message based on the RS transmission. To illustrate, the first UE 115a may determine the best beam or setting to use to monitor and receive the paging message based on the RS. The paging message may include or correspond to a wake-up message.

[0107]

[0120] At 750, the base station 105 and the first UE 115a perform an RRC operation. For example, the base station 105 and the first UE 115a exchange RRC messages to switch the first UE 115a from a non-connected mode to a connected mode.

[0108]

[0121] At 755, the first UE 115a operates in a connected mode with the base station 105. For example, the first UE 115a switches from an idle mode or an inactive mode to an RRC connected mode with the base station 105. The first UE 115a may transmit and receive data to and from the base station 105 while in the connected mode. In some such implementations, the first UE 115a may be configured with one or more RSs and may receive the RSs from the base station 105 in the connected mode. The one or more RSs and their corresponding configurations may be the same one or more RSs used by a UE in a non-connected mode.

[0109]

[0122] Thus, in the example of Figure 7, the UE performs RS operation in the unconnected mode based on the configuration information broadcast by the network entity while the UE is in the unconnected mode, i.e., the UE receives the RS configuration while not connected to the base station and uses the RS configuration while in the unconnected mode to receive RS for the connected mode.

[0110]

[0123] 8-10 illustrate example diagrams of RS operation according to some aspects. Referring to FIG. 8, FIG. 8 is a diagram 800 illustrating the bandwidth and active bandwidth portion of an RS. In the example of FIG. 8, the diagram illustrates the bandwidth of an RS configuration for a UE in connected mode and the bandwidth of the active bandwidth portion.

[0111]

[0124] As an illustrative example, during operation, the UE may receive or determine an RS configuration having a first bandwidth, as shown in FIG. 8. The UE may also receive or determine that an active BWP for a connected mode UE has a second bandwidth, as shown in FIG. 8. In FIG. 8, the second bandwidth is smaller than the first bandwidth and overlaps a middle portion of the first bandwidth. The non-connected mode UE may determine that the bandwidth of the RS for the non-connected mode UE is the overlap portion in some implementations, i.e., the overlap portion between the bandwidth of the RS indicated by the RS configuration provided to the non-connected mode UE and the bandwidth of the active BWP of the connected mode UE. In other implementations, the UE may determine that the bandwidth of the RS for the non-connected mode UE is the entire bandwidth of the RS configuration, or some other portion thereof. Additional examples are provided below.

[0112]

[0125] In some operating conditions or modes, the bandwidth setting value of the original RS configuration for a UE in connected mode may cause potential problems for a UE operating in non-connected mode. For example, problems may occur when the smallest RB index is not used, when the bandwidth of the step of 4 RB is not used, or when the bandwidth of the RS does not meet the threshold condition. For illustration, the bandwidth of the RS may not be more than 24 RB for CSI-RS or more than 52 RB for TRS. Therefore, the UE and the network may modify such parameters when these parameters are determined by the active BWP bandwidth range of the connected UE.

[0113]

[0126] Regarding the 4RB step problem, the UE and the network can take many different mitigation actions to modify the bandwidth of the RS. As an example, a device may prune the RS bandwidth so that a UE (e.g., connected, disconnected, or both) monitors the RS in a 4RB grid.

[0114]

[0127] As another example, the device may decide to use the original RS configuration, and the RS is transmitted in the entire configured bandwidth of the RS. As yet another example, the device may modify the RS configuration signaling to reduce the granularity for determining the bandwidth. For illustration, the granularity may be reduced from 4 RBs to 1 to provide finer granularity.

[0115]

[0128] As an additional example, the network may signal the BWP configuration of the associated BWP for the connected mode UE. Such information may enable the non-connected mode UE to calculate the RS bandwidth monitored by the connected mode UE.

[0116]

[0129] With regard to the bandwidth size issue, similar actions may be adopted. For illustration, when the bandwidth of the active BWP of a connected mode UE is less than 24 RBs, the associated CSI-RS may not be used. As another illustration, the bandwidth of the original RS configuration, which may be 24 RBs or more, may be used. As yet another illustration, the RS configuration signaling may be modified to reduce the bandwidth of the original RS configuration to be less than 24 RBs when used by a non-connected mode UE. As an additional illustration, the network may provide an alternative bandwidth, such as by providing an alternative connected mode BWP configuration.

[0117]

[0130] In the case of a TRS, when the bandwidth of an active BWP of a connected mode UE is less than 52 RBs, the associated TRS may not be used. In such implementations, a different RS may be used (e.g., CSI-RS or dedicated RS). Alternatively, in other implementations, the original RS configuration, which may be 52 RBs or more, may be used. In still other implementations, the RS configuration signaling may be modified to reduce the bandwidth of the original RS configuration to be less than 52 RBs when used by a non-connected mode UE. In further implementations, the network may provide an alternative bandwidth, such as by providing an alternative connected mode BWP configuration.

[0118]

[0131] Additionally or alternatively, the SCS of the RS may be configured or determined by the device. In some implementations, the first SCS of the RS in the associated BWP of a connected mode UE is the same as the second SCS of an active BWP for a non-connected mode UE. The UE may be configured to expect to receive an RS with the same SCS as the SCS of its active BWP. In such implementations, the SCS of the RS may not be explicitly configured for a non-connected mode UE.

[0119]

[0132] In some implementations, the carrier index is included in the RS configuration for a UE in a disconnected mode. The carrier index may indicate the carrier on which the RS is transmitted. If the carrier index is not associated with the current serving cell, the RS may be used for neighbor cell measurements, or serving cell tracking and measurements after cell reselection to the carrier. In such implementations, the UE may start monitoring an RS associated with a carrier index other than the carrier index for the previous serving cell when the UE camps on a cell associated with the carrier index.

[0120]

[0133] Referring to FIG. 9, FIG. 9 is a diagram 900 illustrating overlap between an RS and another transmission. In the example of FIG. 9, the diagram illustrates overlap between an RS and a downlink transmission, such as a PDCCH or a PDSCH. In a particular implementation, the PDCCH may be a paging DCI or a paging signal, also known as a page indication (PI) or a wake-up signal (WUS). The PI and WUS may indicate whether the UE will be paged in the next paging occasion (PO). After detecting the PI and / or WUS, the UE determines whether the next PO needs to be monitored and / or processed. In a particular implementation, the PDSCH may be a PDSCH scheduled by a paging DCI or a PDSCH carrying a system information block (SIB).

[0121]

[0134] The network may be configured to take one or more actions to resolve the overlap when it occurs. Alternatively, the network may determine the schedule and adjust the schedule to avoid the overlap in the first place. For example, the base station may generate an RS configuration that does not result in RS overlap.

[0122]

[0135] If overlap occurs, the network may configure the device to handle the overlap in one or more ways. In some implementations, the device determines that the RS is not transmitted if the configured RS occasion has an overlap with another transmission. In other implementations, the device determines puncturing or rate matching of the downlink channel (i.e., PDCCH / PDSCH) around the RS transmission. In still other implementations, the device determines that both the RS and the downlink channel are transmitted. Advanced UEs, such as UEs with multiple antennas, may be able to receive both the RS and the downlink channel even if the transmissions overlap at least partially in frequency and / or time.

[0123]

[0136] Referring to FIG. 10, FIG. 10 is a diagram 1000 illustrating beam combining. In the example of FIG. 10, the diagram illustrates a first diagram of single beam use and a second diagram of beam combining / multiple beam use. Beam combining may be configured to be on, semi-statically configured, or dynamically used based on one or more conditions. For example, a quality condition (e.g., a threshold) may be used to determine whether beam combining should be used. The quality condition may include or correspond to a signal-to-noise ratio (SNR) condition, a signal-to-noise and interference ratio (SINR) condition, a reference signal received power (RSRP) condition, a reference signal received quality (RSRQ) condition, or a combination thereof.

[0124]

[0137] In some implementations, when quality conditions are high and multi-beam combining is not used to improve quality, the UE may use the RS associated with the highest quality SSB, In some such implementations, when the best SSB changes, the UE begins to use the new RS associated with the new best SSB.

[0125]

[0138] In some implementations, when quality conditions are low and multi-beam combining is used to improve quality, the UE may still use the RS associated with the preceding best beam (e.g., the highest quality SSB) and receive a paging message with the preceding best beam corresponding to the preceding best SSB.

[0126]

[0139] A UE may move from cell to cell during operation. When a UE moves from one cell (e.g., a first base station) to another cell (e.g., a second base station), the UE may continue to use the RS configuration from the old cell (e.g., the first base station). For example, when a UE in a non-connected mode moves to another cell, the UE switches to one or more RSs associated with the new cell for tracking loop updates and measurements. In some such implementations, the UE may still use one or more previous RSs in the old cell for neighbor cell measurements when the old cell (e.g., the first base station) becomes a neighbor cell after moving to another cell (e.g., a second base station).

[0127]

[0140] In some implementations, the RS configuration may include quasi-co-location (QCL) information. For example, the base station configures the QCL of an RS (e.g., an RS already configured in a connected mode UE) with a TCI state having SSB as a source when the RS is configured in a non-connected mode UE.

[0128]

[0141] In some such implementations, each RS resource is QCL'd with only one SSB, which may reflect the configuration of paging messages since each paging message transmission is associated with a single SSB.

[0129]

[0142] In some other implementations, the base station transmits the RS in a wide SSB beam to the unconnected UEs. Such transmission may be to match the beam of the RS with the beam of the paging PDCCH and paging messages.

[0130]

[0143] Generally, pages for UEs in unconnected mode (e.g., idle / inactive mode) are transmitted in an SSB beam, while CSI-RS for UEs in connected mode may be transmitted in a narrower, more directional beam. In some implementations, an unconnected mode UE is configured with multiple RSs QCL'd with the same SSB. In some such implementations, all RSs QCL'd with the same SSB have the same beam (e.g., the same beam width and direction). In this way, the UE may not perform very fine beam management based on beams narrower than SSB beams.

[0131]

[0144] For a non-connected mode UE, multiple RS resources associated with different SSBs should be configured. In some implementations, the CSI-RS for beam failure recovery or radio link failure (RLF) detection for a connected mode UE may have a wide beam. The set of CSI-RS resources configured in the UE for beam failure recovery / RLF may be associated with all SSBs. Thus, such RS and beams may be suitable candidates for paging message reception operation for a non-connected mode UE. In certain implementations, all SSBs and QCL'd RSs transmitted on a cell may be transmitted to have enough QCL'd RSs for multiple connected UEs.

[0132]

[0145] The network may determine and provide one or more other configurations of the RS for the UE in the disconnected mode. Such other configurations may include a repetition setting, a number of ports setting, a periodicity setting, a frequency domain density setting, and one or more power control offset settings. The repetition setting may be set to "on" to allow the UE to process more symbols of the same SSB and QCL'd RS (e.g., CSI-RS).

[0133]

[0146] The port number setting value network may reduce the number of configured ports (e.g., to 1), such as when the RS is a CSI-RS. For example, the UE may assume a single port transmission of the CSI-RS, e.g., port 0. A TRS is only transmitted on a single port, and therefore the base station does not indicate port information for such an RS.

[0134]

[0147] The periodicity setting value may include the periodicityAndOffset IE. The network may adjust it to a relatively large period to avoid the downlink signal and power being intercepted. Currently, the minimum period is 4 slots for CSI-RS and 10 ms (e.g., 52 RB or less) for TRS. In some implementations, high-density RS (e.g., high-density CSI-RS) is suitable for time tracking. For example, single port CSI-RS and TRS may have the highest density of 3.

[0135]

[0148] The first power offset setting value may include powerControlOffset. When the RS is used for a non-connected UE, the first power offset setting value indicates a power difference between the RS and the associated paging PDCCH and paging PDSCH. The second power offset setting value may include powerConfrolOffsetSS. When the RS is used for a non-connected mode UE, the second power offset setting value indicates a power difference between the RS and the QCLed SSB.

[0136]

[0149] In some implementations, the RS configuration information is sent during the RRC release, indicated by an RRC release message. In other implementations, the RS configuration information is sent in a separate message that is separate from the RRC release communication (i.e., separate from the RRC release message).

[0137]

[0150] In the examples of Figures 4-7, the configuration parameters of the RS may be updated by a message when the UE enters a non-connected mode (e.g., idle / inactive) or by rules defined in the network, region, or standard. Illustrative examples of such parameters that may be updated or adjusted include port information, periodicityAndOffset information, RS power offset information, QCL information, or combinations thereof. By way of example, the port count setting may be changed to sinusoidal ports. As another example, the periodicity / offset setting may be increased. As yet another example, the RS power offset setting may be increased. As an additional example, the TCI state may be updated to indicate the use of SSB as the QCL source.

[0138]

[0151] In some implementations, the RS configuration information may indicate which particular RSs are available for a UE in a non-connected mode when multiple RS resources are configured, such as while the UE is in a connected mode. For example, the particular RSs may be indicated (e.g., signaled) by the RS configuration information, or the particular RSs may be determined based on one or more parameters or conditions of the RSs indicated by the RS configuration information. For illustration, the network may indicate a particular RS or a subset of RSs based on a list of IDs for the configured RSs in the RS configuration information. This RS configuration information or indication may be in an RRC message (e.g., an RRC release message) or another message. This indication may be sent with the RS configuration information (e.g., first RS configuration information indicating one or more RSs) or may be indicated by additional RS configuration information (e.g., second RS configuration information). The indication information may include a resource set ID or resource ID associated with the RS resources. As another example of a determined device, the device may determine a particular RS or a subset of RSs to use from multiple RSs based on parameters of the RSs. For example, the device may use the RS resource (or multiple RS resources) with the smallest ID. As another example, the device may use an RS resource (or multiple RS resources) with a particular port setting (e.g., port 0), or a particular density setting, or both. Although two examples are shown, the device may use a particular setting of any of the parameters described above. Alternatively, all RSs for a UE in non-connected mode may be used.

[0139]

[0152] Additionally or alternatively, the RS configuration information may indicate an expiration for an RS or set of RSs. The expiration time may define a period during which the UE may assume that the RS is available for use by the UE in unconnected mode, and the expiration time may indicate this time from when the UE enters unconnected mode. The expiration time may be indicated in any type of unit. For example, the expiration time may be indicated by a number of seconds (e.g., milliseconds or microseconds), slots, radio frames, paging cycles, etc. Alternatively, the expiration time may be indicated as 0 or null, which may configure one or more RSs to have infinite duration or to have no expiration time.

[0140]

[0153] Additionally or alternatively, in other implementations, one or more of the operations of Figures 4-10 may be added, removed, or substituted. For example, in some implementations, the example steps of Figures 5 and 7 may be used together. For illustration, the broadcast of the RS configuration of Figure 6 may be used together with the transmission of the RS configuration information in the RRC release message of Figure 5. As another example, some of the operations of Figures 8-10 may be used together with any of the steps of Figures 4-7.

[0141]

[0154] FIG. 11 is a flow diagram illustrating example blocks executed by a UE configured according to an aspect of the disclosure. The example blocks are also described with respect to the UE 115 as shown in FIG. 13. FIG. 13 is a block diagram illustrating the UE 115 configured according to an aspect of the disclosure. The UE 115 includes the structure, hardware, and components as shown for the UE 115 of FIG. 2 and / or FIG. 4. For example, the UE 115 includes a controller / processor 280 that operates to execute logic or computer instructions stored in memory 282 as well as controls the components of the UE 115 that provide the features and functionality of the UE 115. The UE 115 transmits and receives signals via wireless radios 1301a-r and antennas 252a-r under the control of the controller / processor 280. 2 for the UE 115, including various components and hardware, including modulator / demodulators 254a-r, MIMO detector 256, receive processor 258, transmit processor 264, and TX MIMO processor 266. As shown in the example of FIG. 13, memory 282 stores connected mode logic 1302, non-connected mode logic 1303, RS logic 1304, RS configuration data 1305, RS resource data 1306, and configuration data 1307.

[0142]

[0155] At block 1100, a wireless communication device, such as a UE, operates in an unconnected mode. For example, the UE 115 operates in an RRC idle mode or an RRC inactive mode, as described with reference to Figures 4-10. The unconnected mode may include or correspond to an RRC mode in which the UE is not connected to a base station.

[0143]

[0156] In block 1101, the UE 115 determines reference signal (RS) configuration settings for a non-connected mode. For example, the UE 115 receives RS configuration information (e.g., 406) from the base station 105 using the wireless radios 1301a-r and antennas 252a-r as described with reference to Figures 4-10. The RS configuration information (e.g., 406) may be indicated by an RS configuration message 452, such as an RRC release message, another non-RRC release message, or a broadcast message. The RS configuration information may include or correspond to RS availability information. The non-connected mode manager 416, the non-connected mode logic 1303, and / or the RS logic 1304 of the UE 115 may determine the RS configuration indicated by the RS configuration information.

[0144]

[0157] In block 1102, the UE 115 monitors reference signals based on RS configuration settings. For example, the non-connected mode manager 416, the non-connected mode logic 1303 and / or the RS logic 1304 of the UE 115 use the wireless radios 1301a-r and antennas 252a-r to monitor RS transmissions 454 based on the RS configuration information (e.g., 406 / 1305) as described with reference to FIGS.

[0145]

[0158] In block 1103, the UE 115 receives an RS transmission in an unconnected mode based on an RS configuration setting. For example, the UE 115 receives an RS transmission 454 in an unconnected mode based on an RS configuration setting using the wireless radios 1301a-r and antennas 252a-r as described with reference to FIGS. 4-10. The RS transmission 454 may be an RS for a UE in a connected mode or a dedicated RS for a UE in an unconnected mode. Receiving and processing the RS transmission 454 may enable the UE 115 to more effectively receive and process subsequent messages, such as paging messages, and / or may enable the UE 115 to more effectively transition to a connected mode.

[0146]

[0159] A wireless communication device (e.g., a UE or a base station) may perform additional blocks (or the wireless communication device may be further configured to perform additional operations) in other implementations. For example, the UE 115 may perform one or more operations described above. As another example, the UE 115 may perform one or more aspects presented below.

[0155]

[0168] In a ninth aspect, alone or in combination with one or more of the above aspects, the RS configuration corresponds to an RS configuration provided to the UE in a connected mode, and the UE receives the RS configuration from the network entity while in the connected mode, receives an RS transmission from the network entity while in the connected mode, and receives an RRC release message from the network entity before operating in the non-connected mode.

[0156]

[0169] In a tenth aspect, alone or in combination with one or more of the above aspects, determining the RS configuration setting values ​​for the non-connected mode includes determining the RS configuration setting values ​​based on the received RS setting value information for the connected mode.

[0157]

[0160]

[0173] In a fourteenth aspect, alone or in combination with one or more of the above aspects, determining the RS configuration setting value for the non-connected mode includes determining the RS configuration setting value based on the UE setting value information and the RS configuration provided to the UE in the connected mode.

[0161]

[0174] In a fifteenth aspect, alone or in combination with one or more of the above aspects, the RS availability information indicates a particular RS resource from among a plurality of RS resources for a UE in connected mode, a particular RS resource set from among a plurality of RS resource sets for a UE in connected mode, an expiration time for an RS configuration for a non-connected mode, or a combination thereof.

[0162]
