[0002] This application claims the benefit of U.S. patent application Ser. No. 18 / 502,528, filed on Nov. 6, 2023, entitled “PRIORITIZATION OF EVENT TRIGGERED MOBILITY REPORTS,” and also claims the benefit of U.S. provisional patent application Ser. No. 63 / 484,869, filed on Feb. 14, 2023, entitled “PRIORITIZATION OF EVENT TRIGGERED MOBILITY REPORTS,” both of which are expressly incorporated herein by reference in their entirety. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to reporting of measurements in wireless networks. Several features may enable and provide improved communications, including prioritization of event-triggered mobility reports. Background Art

[0004] Wireless communication networks are 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 communication for multiple users by sharing the available network resources.

[0005] 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 multiple user equipment (UEs). UEs may communicate with base stations via downlinks and uplinks. A downlink (or forward link) refers to the communication link from a base station to a UE, and an uplink (or reverse link) refers to the communication link from a UE to a base station.

[0006] 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 caused by 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 uplink.

[0007] As the demand for mobile broadband access continues to grow, the potential for interference and congested networks grows with more UEs accessing long-range wireless communication networks and more short-range wireless systems deployed in communities. Research and development continue to advance wireless technologies to not only meet the growing demand for mobile broadband access, but also to improve and enhance the user experience with mobile communications.

[0008] The following summarizes some aspects of the present disclosure to provide a basic understanding of the technology discussed. This summary is not an exhaustive overview of all anticipated features of the present disclosure and is neither intended to identify key or important elements of all aspects of the present disclosure nor to delineate the scope of any or all aspects of the present disclosure. The sole purpose of this summary is to provide some concepts of one or more aspects of the present disclosure in a summarized form as a prelude to the more detailed description that will be presented later.

[0028] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to limit the scope of the present disclosure. Instead, the detailed description includes specific details for 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 case, and in some instances, well-known structures and components are shown in block diagram form for clarity of presentation.

[0029] The present disclosure as a whole 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 specific implementations, the techniques and apparatuses may be used in wireless communication networks, such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, 5th generation (5G) or new radio (NR) networks (sometimes referred to as "5G NR" networks, systems or devices), 6G networks, and other communication networks. As described herein, the terms "network" and "system" can be used interchangeably.

[0030] A CDMA network may implement, for example, 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.

[0031] For example, a TDMA network may implement a radio technology such as Global System for Mobile Communications (GSM). The Third Generation Partnership Project (3GPP) defined the standard for the GSM EDGE (Enhanced Data Rates for GSM Evolution) Radio Access Network (RAN), also known as GERAN. GERAN is the radio component of GSM / EDGE, along with the network connecting base stations (e.g., Ater and Abis interfaces) and base station controllers (A interfaces, etc.). The radio access network refers to the component of a GSM network through which phone calls and packet data are routed from the public switched telephone network (PSTN) and the internet to subscriber handsets (also known as user terminals or user equipment (UE)), and vice versa. A mobile phone operator's network may include one or more GERANs, which, in the case of UMTS / GSM networks, may be coupled with a UTRAN. Additionally, an operator's network may include one or more LTE networks, or one or more other networks. Different network types may use different radio access technologies (RATs) and RANs.

[0032] OFDMA networks can 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 part of the Universal Mobile Telecommunications System (UMTS). Specifically, Long Term Evolution (LTE) is a version of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents provided by an organization called the "3rd Generation Partnership Project" (3GPP), and cdma2000 is described in documents from an organization called the "3rd Generation Partnership Project 2" (3GPP2). These various radio technologies and standards are either known or under development. For example, 3GPP is a collaboration between a group of telecommunications associations to define globally applicable third generation (3G) mobile phone specifications. 3GPP LTE is a 3GPP initiative aimed at improving the UMTS mobile phone standard. 3GPP can define specifications for next-generation mobile networks, mobile systems, and mobile devices. This disclosure may describe certain aspects with reference to LTE, 4G, or 5G NR technologies; however, the description is not intended to be limited to a particular technology or application, and one or more aspects described with reference to one technology may be understood to be applicable to another technology. Additionally, one or more aspects of this disclosure may relate to shared access to wireless spectrum between networks using different radio access technologies or radio air interfaces.

[0033] 5G networks are expected to have diverse deployments, diverse spectrum, and diverse services and devices that can be implemented using a unified air interface based on OFDM. To achieve these goals, in addition to developing new radio technologies for 5G NR networks, further enhancements to LTE and LTE-A are also being considered. 5G NR will be able to scale to provide coverage (1) to massive Internet of Things (IoT), with ultra-high density (e.g., about 1M nodes / km) 2 ), ultra-low complexity (e.g., on the order of tens of bits / second), ultra-low power consumption (e.g., on the order of 10+ years battery life), and deep coverage with the ability to reach challenging locations; (2) includes mission-critical control with strong security to protect sensitive personal, financial, or classified 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 a wide range of mobility or lack of mobility; and (3) has enhanced mobile broadband, including very high capacity (e.g., on the order of 10 Tbps / km 2 ), extremely high data rates (e.g., multi-Gbps rates, 100+Mbps user experienced rates), and deep awareness with advanced discovery and optimization.

[0034] Devices, networks, and systems may be configured to communicate via one or more portions of the electromagnetic spectrum. The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / 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). Frequencies between FR1 and FR2 are typically referred to as mid-band frequencies. 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 arises for FR2, which is often (interchangeably) referred to as the "millimeter wave" (mmWave) band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "mmWave" band by the International Telecommunication Union (ITU).

[0035] In view of the above aspects, unless otherwise specifically stated, it should be understood that if the term "sub-6 GHz" is used herein, it can broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "mmWave" is used herein, it can broadly refer to frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

[0036] 5G NR devices, networks, and systems can be implemented using optimized OFDM-based waveform features. These features may include scalable parameter sets and transmit time intervals (TTIs); a common flexible framework that efficiently multiplexes services and features using 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 parameter sets and the scaling of subcarrier spacing in 5G NR can efficiently address the operation of diverse services across diverse spectrums and diverse deployments. For example, in various outdoor and macro coverage deployments with less than 3 GHz FDD or TDD implementations, the subcarrier spacing may appear as 15 kHz on bandwidths such as 1 MHz, 5 MHz, 10 MHz, and 20 MHz. For various other outdoor and small cell coverage deployments with TDD greater than 3 GHz, the subcarrier spacing may appear as 30 kHz on 80 MHz / 100 MHz bandwidth. For various other indoor broadband implementations, using TDD in the unlicensed portion of the 5 GHz band, the subcarrier spacing may occur at 60 kHz over a 160 MHz bandwidth. Finally, for various deployments transmitting over mmWave components using TDD at 28 GHz, the subcarrier spacing may occur at 120 kHz over a 500 MHz bandwidth.

[0037] 5G NR's scalable parameter set facilitates scalable TTIs for diverse latency and quality of service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmission to start on symbol boundaries. 5G NR also anticipates a self-contained integrated subframe design, where uplink or downlink scheduling information, data, and acknowledgments are located in the same subframe. The self-contained integrated subframe supports communications in unlicensed or contention-based shared spectrum, and adaptive uplink or downlink can be flexibly configured on a per-cell basis to dynamically switch between uplink and downlink to meet current traffic needs.

[0038] For clarity, certain aspects of the devices and techniques may be described below with reference to example 5G NR implementations or in a 5G-centric manner, and 5G terminology may be used as illustrative examples in portions of the description below; however, the description is not intended to be limited to 5G applications.

[0039] Furthermore, it should be understood that in operation, a wireless communication network adapted according to the concepts herein can operate using any combination of licensed or unlicensed spectrum, depending on load and availability. Therefore, it will be apparent to one of ordinary skill in the art that the systems, devices, and methods described herein can be applied to other communication systems and applications beyond the specific examples provided.

[0040] Although various aspects and specific implementations are described in this application by way of illustration of some examples, it will be understood by those skilled in the art that additional specific implementations and use cases may be generated in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, specific implementations or uses may be implemented via integrated chip implementations or other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail equipment or purchasing equipment, medical equipment, AI-enabled devices, etc.). Although some examples may or may not specifically point to use cases or applications, the applicability of various types of the described innovations may occur. The scope of specific implementations may range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems in combination with one or more of the described aspects. In some practical environments, the devices in combination with the various aspects and features described may also necessarily include additional components and features for implementing and practicing the various aspects claimed and described. It is intended that the innovations described herein may be practiced in a wide variety of implementations of different sizes, shapes, and configurations, including both large and small devices, chip-level components, multi-component systems (e.g., radio frequency (RF) chains, communication interfaces, processors), distributed arrangements, end-user devices, etc.

[0041] Figure 1 1 is a block diagram illustrating details of an example wireless communication system according to one or more aspects. The wireless communication system may include a wireless network 100. The wireless network 100 may, for example, include a 5G wireless network. As will be appreciated by those skilled in the art, Figure 1 Components appearing in are likely to have related corresponding components in other network arrangements, including, for example, cellular-style network arrangements as well as non-cellular-style network arrangements (e.g., device-to-device or peer-to-peer or ad hoc network arrangements, etc.).

[0042] Figure 1The illustrated wireless network 100 includes a number of base stations 105 and other network entities. A base station can be a station that communicates with a UE and can also be referred to as an evolved Node B (eNB), a next-generation eNB (gNB), an access point, etc. Each base station 105 can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" can refer to a specific geographic coverage area of ​​a base station or a base station subsystem serving that coverage area, depending on the context in which the term is used. In specific implementations of the wireless network 100 herein, the base stations 105 can be associated with the same operator or different operators (e.g., the wireless network 100 can include multiple operator wireless networks). In addition, in specific implementations of the wireless network 100 herein, the base stations 105 can 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 can be operated by more than one network operating entity. In some other examples, each base station 105 and UE 115 can be operated by a single network operating entity.

[0043] A base station may provide communication coverage for a macro cell or a small cell (e.g., a pico cell or femto cell) or other type of cell. A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs that have a service subscription with a network provider. A small cell (such as a pico cell) will generally cover a relatively small geographic area and may allow unrestricted access by UEs that have 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, in addition to unrestricted access, may also provide restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in a home, etc.). A base station for a macro cell may be referred to as a macro base station. A base station for a small cell may be referred to as a small cell base station, a pico base station, a femto base station, or a home base station. In Figure 1 In the example shown, base stations 105d and 105e are conventional macro base stations, while base stations 105a-105c are macro base stations implemented using one of 3D, full-dimensional (FD), or massive MIMO. Base stations 105a-105c utilize their higher-dimensional MIMO capabilities to employ 3D beamforming in elevation and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station, which can be a home node or a portable access point. The base station can support one or more (e.g., two, three, four, etc.) cells.

[0044] Wireless network 100 may support synchronous or asynchronous operation. For synchronous operation, base stations may have similar frame timing, and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, base stations may have different frame timing, and transmissions from different base stations may not be aligned in time. In some cases, the network may be enabled or configured to handle dynamic switching between synchronous and asynchronous operation.

[0045] UEs 115 are dispersed throughout the wireless network 100, and each UE can be stationary or mobile. It should be understood that although mobile devices are generally referred to as UEs in the standards and specifications promulgated by 3GPP, such devices may additionally or otherwise be referred to by those skilled in the art as mobile stations (MSs), subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals (ATs), mobile terminals, wireless terminals, remote terminals, handsets, terminals, user agents, mobile clients, clients, gaming devices, augmented reality devices, vehicle components, vehicle devices, or vehicle modules, or some other suitable terminology. In this document, a "mobile" device or UE does not necessarily have the ability to move and can be stationary. Some non-limiting examples of mobile devices may include, for example, one or more implementations of UE 115, including mobile phones, cellular phones, smartphones, Session Initiation Protocol (SIP) phones, wireless local loop (WLL) stations, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablet devices, and personal digital assistants (PDAs). The mobile device may additionally be an IoT or "Internet of Everything" (IoE) device, such as a car or other transportation vehicle, a satellite radio, a global positioning system (GPS) device, a global navigation satellite system (GNSS) device, a logistics controller, a drone, a multi-rotor helicopter, a quadcopter, smart energy or security equipment, solar panels or solar arrays, urban lighting, tap water or other infrastructure; industrial automation and enterprise equipment; consumer and wearable devices, such as glasses, wearable cameras, smart watches, health or fitness trackers, mammalian implantable devices, gesture tracking devices, medical devices, digital audio players (e.g., MP3 players), cameras, game consoles, etc.; and digital home or smart home devices, such as home audio, video and multimedia devices, appliances, sensors, vending machines, smart lighting, home security systems, smart meters, 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 also be referred to as an IoE device. Figure 1The UEs 115a-115d of the specific implementation illustrated in FIG are examples of mobile smartphone-type devices accessing the wireless network 100. A UE may also be a machine specifically configured for connected communications, including machine type communications (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. Figure 1 The UEs 115e-115k illustrated in FIG. 1 are examples of various machines configured for communication that access the wireless network 100.

[0046] A mobile device, such as UE 115, may be able to communicate with any type of base station, whether macro, pico, femto, relay, etc. Figure 1 In the figure, the communication links (represented as lightning balls) indicate wireless transmissions between a 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, as well as backhaul transmissions between base stations. A UE may operate as a base station or other network node in some scenarios. Backhaul communications between base stations of wireless network 100 may be performed using wired or wireless communication links.

[0047] In operation, at wireless network 100, base stations 105a-105c use 3D beamforming and coordinated spatial techniques (e.g., coordinated multipoint (CoMP) or multi-connectivity) to serve UEs 115a and 115b. Macro base station 105d performs backhaul communications with base stations 105a-105c and small cells (base station 105f). Macro base station 105d also transmits multicast services that are subscribed to and received by UEs 115c and 115d. Such multicast services may include mobile TV or streaming video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber Alerts or Gray Alerts.

[0048] The wireless network 100 of the embodiment supports mission-critical communications with ultra-reliable and redundant links for mission-critical devices such as UE 115e, which is a drone. The redundant communication links with UE 115e include links from macro base stations 105d and 105e, as well as small cell base station 105f. Other machine-type devices, such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device), can communicate directly with base stations such as small cell base station 105f and macro base station 105e via the wireless network 100, or in a multi-hop configuration by communicating with another user device that relays its information to the network, such as UE 115f communicating temperature measurement information to smart meter UE 115g, which then reports it to the network via small cell base station 105f. The wireless network 100 may also provide additional network efficiency through dynamic, low-latency TDD communications or low-latency FDD communications (eg, in a vehicle-to-vehicle (V2V) mesh network between UEs 115i-115k communicating with a macro base station 105e).

[0049] Figure 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 Figure 1 For the restricted association scenario (as mentioned above), the base station 105 can be any one of the base stations in the UE and one of the UEs. Figure 1 The small cell base station 105f in the base station 105f, and the UE 115 may be a UE 115c or 115d operating in the service area of ​​the base station 105f, which will be included in the list of accessible UEs of the small cell base station 105f in order to access the small cell base station 105f. The base station 105 may also be some other type of base station. Figure 2 As shown in FIG, the base station 105 may be equipped with antennas 234a through 234t, and the UE 115 may be equipped with antennas 252a through 252r for facilitating wireless communication.

[0050] At the base station 105, the transmit processor 220 may receive data from the data source 212 and control information from the controller 240 (such as a processor). The control information may be for the physical broadcast channel (PBCH), the physical control format indicator channel (PCFICH), the physical hybrid ARQ (automatic repeat request) indicator channel (PHICH), the physical downlink control channel (PDCCH), the enhanced physical downlink control channel (EPDCCH), the MTC physical downlink control channel (MPDCCH), etc. The data may be for the 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 separately to obtain data symbols and control symbols. The transmit processor 220 may also generate reference symbols, such as for the primary synchronization signal (PSS) and the secondary synchronization signal (SSS), as well as cell-specific reference signals. 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 modulators (MODs) 232a through 232t. For example, the spatial processing performed on the data symbols, control symbols, or reference symbols may include precoding. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Additionally or alternatively, each modulator 232 may process the output sample stream (e.g., by analog-converting, amplifying, filtering, and frequency upconverting it) to obtain a downlink signal. The downlink signals from modulators 232a through 232t may be transmitted via antennas 234a through 234t, respectively.

[0051] At the UE 115, antennas 252a through 252r may receive downlink signals from the base station 105 and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a corresponding 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 through 254r, perform MIMO detection on the received symbols as needed, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, 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.

[0052] On the uplink, at the UE 115, a transmit processor 264 may receive and process data from a data source 262 (e.g., for a physical uplink shared channel (PUSCH)) and control information from a controller 280 (e.g., for a physical uplink control channel (PUCCH)). Additionally, the transmit processor 264 may generate reference symbols for reference signals. The symbols from the transmit processor 264 may be pre-decoded by a TX MIMO processor 266, if necessary, further processed by modulators 254a through 254r (e.g., for SC-FDM, etc.), and transmitted to the base station 105. At the base station 105, the uplink signal from the UE 115 may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if necessary, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 115. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller 240.

[0053] The controllers 240 and 280 may direct the 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 for the techniques described herein, such as to perform or direct the execution of various processes for the techniques described herein. Figures 6 to 9 Memories 242 and 282 may store data and program codes for base station 105 and UE 115, respectively. Scheduler 244 may schedule UEs for data transmission on the downlink or uplink.

[0054] 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) 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 process to compete for access to the spectrum. For example, the UE 115 or the base station 105 may perform a listen-before-talk or listen-before-transmit (LBT) process (such as a clear channel assessment (CCA)) before communicating to determine whether the shared channel is available. In some embodiments, the CCA may include an energy detection process to determine whether there are any other active transmissions. For example, the device may infer that a change in the received signal strength indicator (RSSI) of the power meter indicates that the channel is occupied. In particular, signal power concentrated in a certain bandwidth and exceeding a predetermined noise floor may indicate another wireless transmitter. CCA may also include detection of a specific sequence that indicates the use of the channel. For example, another device may send a specific preamble before sending a data sequence. In some cases, the LBT process may include the wireless node adjusting its own backoff window based on the amount of energy detected on the channel or acknowledgement / negative acknowledgement (ACK / NACK) feedback for its own transmitted packets (as an indication of a collision).

[0055] The deployment of a communication system (such as a 5G New Radio (NR) system) can be arranged in a variety of ways with various components or constituent 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 functionality 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) can be implemented as a converged base station (also known as a standalone BS or a monolithic BS) or a decomposed base station.

[0056] 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 also be implemented as a virtual unit, namely a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0057] Base station type operation or network design can take into account the aggregated nature of base station functionality. For example, a disaggregated base station can be utilized in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Disaggregation can include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which can enable flexibility in network design. Various units of a disaggregated base station or disaggregated RAN architecture can be configured for wired or wireless communication with at least one other unit.

[0058] The present disclosure provides systems, devices, methods and computer-readable media for supporting prioritization of event-triggered mobility reports, such as when two or more reports are scheduled to be sent using the same resources. For example, a UE may measure a reference signal transmitted by a network node (such as a base station) that is a candidate serving cell. Based on the measured reference signal, the UE may determine that a triggering condition for transmitting a first report is met. For example, the UE may determine that the signal quality from the network node is better than the signal quality from the current serving cell. However, the transmission of the first report may be configured to be performed on the same resources (such as the same time resources and / or frequency resources) as the transmission of another second report. The UE may determine the priority of the first report and the second report, such as based on the report types of the first report and the second report and other characteristics of the first report and the second report. The UE may then use resources to transmit the first report based on determining that the triggering condition is met and the priority of the first report and the second report. Therefore, conflicts between reports configured to be transmitted using the same resources may be resolved.

[0059] Specific implementations of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages or benefits. In some aspects, the present disclosure provides techniques for prioritizing event-triggered mobility reports. Such prioritization may allow conflict resolution when reports are configured to be sent using the same resources. For example, sending such reports based on their priority may allow higher priority information to be provided to the base station before lower priority information, thereby improving network efficiency. As an example, such prioritization may increase the flexibility of the timing of sending mobility reports, thereby allowing the UE to transfer more quickly as network conditions change. Such transfer may increase signal strength to the UE and reduce the UE's power consumption.

[0060] Figure 3 302d. An example network 300 is shown in FIG. A first UE 304 may be served by a first serving cell 302A. Candidate serving cells 302b-302d may transmit reference signals for measurement by UE 304 to facilitate Layer 1 / Layer 2 Triggered Mobility (LTM), thereby allowing the UE to transition from being served by the current serving cell 302a to being served by one of the candidate serving cells 302b-302d. For example, L1 / L2 signaling for handovers between serving cells may facilitate mobility in lower layers, thereby introducing less latency than L3 mobility signaling.

[0061] UE 304 may measure one or more Layer 1 (L1) transmissions, such as reference signals, transmitted by candidate serving cells 302b-302d. For example, UE 304 may measure reference signal received power (RSRP) for each of a plurality of reference signals transmitted by candidate serving cells 302b-302d. Based on the measured reference signals, UE 304 may determine that triggering conditions for LTM are met. For example, UE 304 may determine that candidate serving cell 302b has better signal quality than current serving cell 302a. UE 304 may use L1 / L2 signaling to send a report to serving cell 302a that includes measurements of reference signals from candidate serving cell 302b and, in some embodiments, measurements of other reference signals from other candidate serving cells 302c-302d. The report may be sent using resources shared with other reports and transmissions between UE 304 and serving cell 302a. If a report is to be sent using the same resources as another report or other transmission, the UE may compare the priorities of the reports to determine whether and when to send each report.The old serving cell 302a may then hand over the UE 304 to the new serving cell 302b.

[0062] As a specific example, candidate cells 302b-302d can be candidate primary cells (PCells). In some embodiments, separate signaling can be used to transition between serving PCells and secondary cells (SCells). For example, SCell selection can be based on legacy signaling or L1 / L2 signaling, such as downlink control information (DCI) or medium access control element (MAC-CE) signaling. In some embodiments, for example, UE 304 can determine that UE 304 should transition from being served by serving cell 302a to being served by candidate serving cell 302b based on reference signals sent by candidate PCells 302b-302d. Therefore, a single PCell 302b without carrier aggregation or dual connectivity can be selected to serve UE 304 as a new serving cell, and UE 304 can use L1 / L2 signaling to transition from being served by serving cell 302a to being served by new serving cell 302b.

[0063] As another example, UE 304 may be served by serving PCell 302a, while candidate cells 302b-302d may be configured as SCells. In this scenario, UE 304 may receive reference signals from SCells 302b-302d. Based on measurements of these reference signals, old serving PCell 302a may be configured as the SCell, while the selected SCell 302b may be configured as the new serving PCell.

[0064] As another example, in a carrier aggregation scenario, cell 302a may represent the serving carrier group, while cells 302b-302d may represent the candidate carrier group. Based on measurements of reference signals from candidate carrier groups 302b-302d, UE 304 may transition from being served by old carrier group 302a to being served by new carrier group 302b. In such an embodiment, when moving between different carrier groups, the SpCell and SCell may be switched together.

[0065] Reporting of reference signal measurements from candidate serving cells 302b-302d can be performed using L1 / L2 signaling and can coexist with other periodic, semi-periodic, and aperiodic reports. In some embodiments, UE 304 can use the same resources allocated for the transmission of other periodic, semi-periodic, and aperiodic reports to transmit LTM reports triggered by measurements of reference signals from candidate serving cells 302b-302d to serving cell 302a. When the same resources are used for both LTM signaling and the transmission of other reports, prioritizing such coexistence reports can improve efficiency in supporting LTM and resolving conflicts.

[0066] Figure 4 is a block diagram of an example wireless communication system 400 that supports prioritization of event-triggered mobility reports according to one or more aspects. In some examples, the wireless communication system 400 can implement aspects of the wireless network 100. The wireless communication system 400 includes a UE 115 and a base station 105. Although one UE 115 and one base station 105 are illustrated, in some other implementations, the wireless communication system 400 can generally include multiple UEs 115 and can include more than one base station 105. The UE 115 and the base station 105 can be examples of network nodes.

[0067] The UE 115 may include various components (such as structures, hardware components) for performing one or more functions described herein. For example, these components may include one or more processors 406 (hereinafter collectively referred to as "processors 406"), one or more memory devices 408 (hereinafter collectively referred to as "memory 408"), one or more transmitters 420 (hereinafter collectively referred to as "transmitters 420"), and one or more receivers 422 (hereinafter collectively referred to as "receivers 422"). The processor 406 may be configured to execute instructions stored in the memory 408 to perform the operations described herein. In some specific implementations, the processor 406 includes or corresponds to one or more of the receive processor 258, the transmit processor 264, and the controller 280, and the memory 408 includes or corresponds to the memory 282.

[0068] Memory 408 includes or is configured to store reference signal information 410, trigger condition information 412, and report information 414. Reference signal information 410 may include information indicating one or more resources on which reference signals are to be transmitted, information indicating one or more measurements to be performed on the one or more reference signals, information indicating one or more measurements performed on the one or more reference signals (such as the values ​​of the one or more measurements), one or more cell identifiers (IDs) associated with the one or more reference signals, one or more reference signal IDs, one or more sounding reference signal (SRS) port numbers for beams used for the one or more reference signals, and other reference signal information. Trigger condition information 410 may include one or more trigger conditions for transmitting one or more reports (such as LTM reports) based on the one or more measurements of the one or more reference signals. Report information 414 may include information indicating one or more items included in a report, such as a cell ID, a reference signal ID, a measured RSRP value, other measured parameters, one or more priority values ​​for one or more reports and / or portions of one or more reports, one or more indicators indicating whether to transmit a report as a result of a comparison of the priority of the report with one or more other reports, one or more portions of a report, and other information. Report information 414 may include one or more channel state information (CSI) reports generated based on one or more measurements of one or more reference signals from one or more candidate serving cells. Report information 414 may also include information for other uplink control information (UCI), such as ACK / NACK information, status request information, and other information.

[0069] The transmitter 420 is configured to transmit reference signals, control information, and data to one or more other devices, and the receiver 422 is configured to receive reference signals, synchronization signals, control information, and data from one or more other devices. For example, the transmitter 420 may transmit signaling, control information, and data to the base station 105, and the receiver 422 may receive signaling, control information, and data from the base station. In some implementations, the transmitter 420 and the receiver 422 may be integrated into one or more transceivers. Additionally or alternatively, the transmitter 420 or the receiver 422 may include or correspond to a reference signal. Figure 2 One or more components of the UE 115 are described.

[0070] UE 115 may include a reference signal measurement module 416 for measuring one or more reference signals transmitted by one or more candidate serving cells. For example, reference signal measurement module 416 may cause UE 115 to measure RSRP of one or more reference signals transmitted by one or more base stations other than serving base station 105. UE 115 may also include a report generation module 418. When one or more measured reference signals meet a trigger condition (such as a trigger condition of trigger condition information 412), report generation module 418 may cause UE 115 to generate a report (such as a CSI report) and may cause UE 115 to send the report to base station 105. If the report is to be sent on the same resources as other UCI (such as another CSI report), report generation module 418 may compare the priority of the report with one or more priorities of other reports to be sent using the same resources. When a report is determined to be sent using the same set of time and frequency resources, the report may be determined to be sent on the same resources as other UCI. Report generation module 418 may cause UE 115 to send the report based on the comparison of the priority of the report with the priorities of the other reports.

[0071] The base station 105 may include various components (such as structural components, hardware components) for performing one or more functions described herein. For example, these components may include one or more processors 424 (hereinafter collectively referred to as "processor 424"), one or more memory devices 426 (hereinafter collectively referred to as "memory 426"), one or more transmitters 436 (hereinafter collectively referred to as "transmitter 436"), and one or more receivers 438 (hereinafter collectively referred to as "receiver 438"). The processor 424 may be configured to execute instructions stored in the memory 426 to perform the operations described herein. In some specific implementations, the processor 424 includes or corresponds to one or more of the receive processor 238, the transmit processor 220, and the controller 240, and the memory 426 includes or corresponds to the memory 242.

[0072] Memory 426 includes or is configured to store report information 428 and configuration information 430. Report information 428 may include, for example, report information 414 and other report information received from UE 115. Configuration information 430 may include configuration information for configuring UE 115 to measure one or more reference signals transmitted by one or more candidate serving base stations other than base station 105, information about one or more triggering conditions for triggering a handover of UE 115 from base station 105 to a different candidate serving base station, and other configuration information.

[0073] The transmitter 436 is configured to transmit reference signals, synchronization signals, control information, and data to one or more other devices, and the receiver 438 is configured to receive reference signals, control information, and data from one or more other devices. For example, the transmitter 436 may transmit signaling, control information, and data to the UE 115, and the receiver 438 may receive signaling, control information, and data from the UE. In some implementations, the transmitter 436 and the receiver 438 may be integrated into one or more transceivers. Additionally or alternatively, the transmitter 436 or the receiver 438 may include or correspond to a reference signal. Figure 2 One or more components of a base station 105 are described.

[0074] The base station 105 may also include a configuration module 432 for configuring the UE 115 for LTM. For example, the configuration module 432 may cause the base station 105 to send configuration information 430 to the UE 115 to configure the UE 115 for LTM. The base station 105 may also include a report reception and handover module 434. The report reception and handover module 434 may cause the base station 105 to receive one or more reports (such as one or more L1 / L2 reports) from the UE 115 for triggering a handover of the UE 115 from the base station 105 to a different candidate serving base station. The report reception and handover module 434 may initiate a handover of the UE 115 to the new serving base station upon receiving the report from the UE 115.

[0075] In some implementations, the wireless communication system 400 implements a 5G NR network. For example, the wireless communication system 400 can include a plurality of 5G-capable UEs 115 and a plurality of 5G-capable base stations 105, such as UEs and base stations configured to operate according to a 5G NR network protocol, such as the 5G NR network protocol defined by 3GPP.

[0076] During operation of the wireless communication system 400, the base station 105 may transmit a reference signal 440. In some embodiments, the base station 105 may be a serving base station, and the reference signal 440 may be transmitted by one or more candidate serving base stations different from the base station 105. For example, each of a plurality of candidate serving base stations may transmit the reference signal 440. In some embodiments, the base station 105 may be a PCell, and the one or more reference signals 440 may be transmitted by one or more SCells and received by the UE 115. The reference signal 440 may be, for example, an L1 / L2 reference signal. The UE 115 may receive the reference signal 440 and may perform one or more measurements on the reference signal 440. For example, the UE 115 may measure the RSRP of the reference signal 440. For example, the UE 115 may receive the reference signal 440 from one or more candidate serving cells other than the base station 105, which may be the current serving cell.

[0077] The report generation module 418 of the UE 115 can determine that a triggering condition for handover of the UE 115 from the base station 105 to a different base station is met based on measurements of the one or more reference signals 440, and can generate a report 442 for transmission to the L1 / L2 of the base station 105. In some embodiments, the report generation module 418 can transmit the event-triggered report 442 based on a priority of the event-triggered report 442 and one or more other reports or other UCI configured to be transmitted on the same resources. For example, the UE 115 can compare the priority of the event-triggered report 442 with the priority of another report configured to be transmitted on the same resources, such as the periodic report 444, can determine that the priority of the event-triggered report 442 is higher than the priority of the other report, such as the periodic report 444, and can transmit the event-triggered report 442 based on the determination that the priority of the event-triggered report 442 is higher than the priority of the other report, such as the periodic report 444. In some embodiments, the transmission of the periodic report 444 can be delayed based on the comparison of the priorities, and the event-triggered report 442 can include an indicator, such as an indication in a reserved bit field or an indication in the demodulation reference signal (DMRS) scrambling for the event-triggered report 442, that the event-triggered report 442 is to be transmitted based on the comparison of the priority of the event-triggered report 442 with the priority of one or more other reports. Such an indication can notify the base station 105 that the event-triggered report 442 is to be transmitted in place of the periodic report 444 configured to be transmitted on the resource.

[0078] The base station 105 may receive the event-triggered report 442, and the report reception and handover module 434 may cause the base station 105 to send a handover instruction 448 to the UE 115 and to the selected candidate serving cell. In some embodiments, the base station 105 may send a report configuration 446 to the UE 115. The report configuration 446 may, for example, include information regarding one or more triggering conditions for LTM, an indication of one or more resources to be monitored for one or more reference signals from one or more candidate base stations, and an indication of one or more resources on which the UE 115 should send the event-triggered report 442. Thus, the UE 115 may send the event-triggered report 442 using L1 / L2 resources based on the priority of the event-triggered report and one or more priorities of other UCI to be sent using the same resources.

[0079] A variety of different trigger conditions may be used to trigger the sending of a report (such as a CSI report for LTM). The UE may measure reference signals for multiple beams from multiple candidate serving cells and may send a report based on the results of such measurements. As an example, for a first trigger condition, the trigger condition for sending the report may be met if the strength of the best beam (such as the RSRP of the best beam) among all measured beams or a subset of beams indicated by the serving cell is greater than or less than a threshold or the strength of the best beam of the serving cell with an offset added in some embodiments. As another example, a second trigger condition for sending the report may require the first trigger condition to be met and a change in the ID of the best beam of the candidate serving cell after the previous measurement. As another example, a third trigger condition for sending the report may require a change in the order of the candidate cell IDs associated with good beams. For example, a good beam may be defined as a beam within the highest number of beams having a measured RSRP above a threshold. Figure 5An example diagram 500 is shown in FIG. , illustrating a change in the order of candidate cell IDs associated with good beams. At a first time, a first order 502 of beams associated with reference signal IDs and cell IDs may be determined by measuring one or more reference signals transmitted by one or more cells. At a second time, a second order 504 of beams may be different from the first order 502 of beams. For example, at the first time, a first beam with a cell ID of 5 and an RS ID of 3 may have a higher RSRP than a second beam with a cell ID of 7 and an RS ID of 6. At the second time, the first beam may have a lower RSRP than the second beam. Based on the change in the order of beams, the transmission of a report may be triggered. Similarly, if a new beam is added to the best beam list and an old beam is removed from the best beam list, such as due to deterioration or improvement in signal quality, the order of beams may change, and the transmission of a report may be triggered. Thus, a report, such as a CSI report, may be triggered by the satisfaction of one or more trigger conditions.

[0080] Figure 6 is a flow chart illustrating an example process 600 for supporting prioritization of event-triggered mobility reports in accordance with one or more aspects. The operations of process 600 may be performed by a UE (such as the one described above with reference to FIG. Figure 1 、 Figure 2 or Figure 4 UE115 described or referenced Figure 11 For example, the example operations (also referred to as "blocks") of process 600 may enable UE 115 to support prioritization of event-triggered mobility reports.

[0081] In block 602, the UE may measure a reference signal transmitted by a network node. The network node may be, for example, a candidate serving cell, such as a base station. The reference signal may be, for example, an L1 reference signal, and the UE may measure an L1 metric of the first reference signal, such as RSRP of one or more beams of the first reference signal. In some embodiments, the UE may determine to measure one or more reference signals from one or more candidate serving cells based on a configuration received from the base station, such as a configuration identifying one or more cell IDs (such as a physical cell ID) and a reference signal ID associated with the one or more reference signals measured by the UE. In some embodiments, the UE may identify a physical cell ID and / or a reference signal ID of a reference signal based on the physical cell ID and the reference signal ID detection.

[0082] In block 604, the UE may determine, based on measurements of a reference signal, that a trigger condition for sending a first report is met. For example, the UE may compare one or more measurements of the first reference signal with one or more threshold parameters associated with the trigger condition to determine whether the trigger condition is met. As another example, the UE may compare the measurement of the reference signal with one or more measurements of one or more other reference signals from other candidate serving cells. A first example trigger condition may include a measured parameter of the best beam among all or a subset of beams measured for one or more candidate serving cells being greater than or less than a threshold, or a measured parameter of a serving cell being added to an offset value. A second example trigger condition may include a change in the ID of the best beam determined based on one or more measurements of one or more reference signals after a previous beam measurement. A third example trigger condition may include a change in the order of measured parameters of candidate serving cell IDs associated with good beams, as discussed herein. For example, the third example trigger condition may include a change in the order of the highest number of beams organized based on measured RSRP values. In some embodiments, the trigger condition may include a combination of two or more of the aforementioned example trigger conditions and / or other trigger conditions. In some embodiments, the trigger conditions may mirror those used for Layer 3 (L3) mobility trigger conditions. L1 metrics (such as RSRP of the transmitted reference signal) may require fewer resources to calculate than L3 metrics and may better capture short-term channel variations on a single beam. In some embodiments, the filtered L1 metrics may differ from the cell-level metrics defined for legacy L3 events, such as by filtering only in the time domain. The filtering of the L1 metrics may be predefined in the UE's memory or indicated to the UE by the network node.

[0083] In block 606, the UE may determine that the first resources used for transmission of the first report overlap with the second resources used for transmission of the second report. For example, the same time resources and / or frequency resources or resource sets may be used for L1 / L2 mobility report transmission and other report transmission. The triggered first report may, for example, include UCI, such as a CSI report, transmitted on one or more physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) resources. Thus, the triggered first report (such as a CSI report) may be transmitted on preconfigured PUSCH resources or PUCCH resources, and the base station may perform blind decoding to detect whether the report is triggered. As a specific example, the resources used for the triggered CSI report may overlap with resources used for other UCI types. In such cases, a multiplexing rule may be applied where ACK / NACK UCI is given priority over status report UCI, and status report UCI is given priority over CSI reports. When a report (such as a CSI report) overlaps with another report (such as another CSI report), the priority of the report may be considered when determining the transmission of the report. As an example, the first report may overlap with a periodic second report, a semi-periodic second report, or an aperiodic second report. When the time resources and / or frequency resources allocated for sending the first report overlap with the time resources and / or frequency resources allocated for sending the other report, the first report may overlap with the other report.

[0084] In block 608, a first priority for the first report and a second priority for the second report may be determined. For example, the determination of the first priority may include calculating a first priority metric for the first report based on a first report type of the first report. The first priority metric may be calculated based on the fact that the first report is an event-triggered report triggered by satisfying a trigger condition. The determination of the second priority may include calculating a second priority metric for the second report based on a second report type of the second report. The second priority metric may be calculated based on whether the second report is a periodic report, a semi-periodic report, or an aperiodic report. Thus, the report types used in the calculation of the priority metric may include an event-triggered report type, a periodic report type, a semi-periodic report type, and an aperiodic report type. As a specific example, the priority metric for each report may be determined according to the following equation: iCSI (y,k,c,s)=2·N cell M S y+N cell M S k+M s c+s. N cell It can represent the number of candidate serving cells, M sy may represent the maximum number of reports configured for transmission, y may represent the type of report, c may represent the serving cell ID, k may represent whether L1 RSRP / Signal to Interference and Noise Ratio (SINR) is transmitted, and s may represent the report configuration ID. For example, when the report is aperiodic, y may be set to a value of 0, when the report is a first type of event-triggered report, y may be set to a value of 1, when the report is a second type of event-triggered report, y may be set to a value of 2, when the report is a semi-periodic PUSCH report, y may be set to a value of 3, when the report is a semi-periodic PUCCH report, y may be set to a value of 4, and when the report is periodic, y may be set to a value of 5. Thus, the priority metric value may depend on the type of report for which the priority metric is being calculated. Different types of event-triggered reports may, for example, be associated with different triggering conditions as discussed herein. If L1 RSRP / SINR is transmitted, the k variable may be set to 0, and if L1 RSRP / SINR is not transmitted, the k variable may be set to 1. Reports with lower priority metrics may be given priority for transmission over reports with higher priority metrics. Thus, if all other variables are equal, aperiodic reporting may have higher priority than event-triggered reporting, and event-triggered reporting may have higher priority than semi-periodic reporting or periodic reporting.

[0085] In block 610, the UE may send a first report on the first resource based on the first priority, the second priority, and determining that a triggering condition is satisfied. The first report may, for example, be sent to a second network node, such as a base station configured as a current serving cell. For example, satisfying the triggering condition may trigger the sending of the report by the UE, and the UE may determine a time for sending the first report based on a comparison of the priorities of the first report and the second report. For example, if the first report has a higher priority than the second report, the first report may be sent before the second report, and the sending of the second report may be delayed. Thus, the UE may compare the priorities of LTM reports configured to be sent using the same resource, and may prioritize the sending of the reports based on the comparison of the priorities.

[0086] The first report sent in block 610 may include one or more cell IDs (such as a physical cell ID (PCI)) and one or more reference signal IDs (such as one or more beam IDs or one or more transmit configuration indicator (TCI) IDs) associated with one or more measurements (such as one or more RSRP measurements) included in the report. In some embodiments, the first report may include a group-based beam report of beam pairs that the UE is configured to receive and transmit simultaneously (such as for simultaneous DL / UL transmission and reception of a candidate cell). In some embodiments, the first report may include one or more SRS port numbers for each reported beam for the report associated with the one or more reference signal IDs. In some embodiments, the first report may include an indication that a priority sorting of the first report is performed to notify the base station that the first report is an event-triggered report. For example, if a periodic report or a semi-periodic report is scheduled to be sent on a resource, and the first report is sent instead based on a comparison of the priorities of the first report and the periodic report or the semi-periodic report, the base station may expect the periodic report or the semi-periodic report instead of the first report. In some embodiments, the first report and the periodic report or semi-periodic report may have the same payload and format, but may include different measurements for different cells. Therefore, blind decoding by the base station may not always allow the base station to determine the type of report received. Therefore, when the first report is sent on the PUCCH, for example, based on a comparison of a priority value, an indication that the report is a triggered report may be included in the report. Such an indication may, for example, include a bit or bit field indicating that the report is sent as a result of the comparison of the priority value. As another example, such an indication may include the use of a specific scrambling sequence for the reported DMRS.

[0087] As a specific example, if the first report has a higher priority than the second report, such as with respect to Figure 6 As described above, the UE may send the first report before sending the second report. Figure 7 is a flow chart illustrating an example process 700 for supporting prioritization of event-triggered mobility reports in accordance with one or more aspects. The operations of process 700 may be performed by a UE (such as the one described above with reference to FIG. Figure 1 、 Figure 2 or Figure 4 UE 115 described or referenced Figure 11 For example, the example operations (also referred to as "blocks") of process 700 may enable UE 115 to support prioritization of event-triggered mobility reports.

[0088] In block 702, the UE may determine that the first priority is greater than the second priority. Figure 6This determination is made by comparing the priority value determined at block 608 of FIG.

[0089] In block 704, the UE may delay sending the second report based on determining that the first priority is greater than the second priority. For example, the UE may use the first resource to send the first report, such as Figure 6 The process may be described as in block 610 of , and sending of the second report scheduled to be sent using the first resource may be delayed until a later time.

[0090] In block 706, the UE may receive a handover instruction after sending the first report. For example, when a second network node (such as a base station configured as a different current serving cell than the first network node) receives the first report, the second network node may determine that the UE should be transferred to a new serving base station (such as the serving base station indicated by the first report). The base station may initiate a handover procedure, and the UE may receive a handover instruction from the base station as part of the handover procedure.

[0091] In some embodiments, regarding Figure 6 and Figure 7 The size of the described first report may exceed the maximum size requirement for transmission on the first resource. Accordingly, the UE may prioritize specific entries of the report and may discard one or more entries of the report to allow the report to remain within the maximum size requirement of the first resource. Figure 8 is a flow chart illustrating an example process 800 for supporting prioritization of event-triggered mobility reports in accordance with one or more aspects. The operations of process 800 may be performed by a UE (such as the one described above with reference to FIG. Figure 1 、 Figure 2 or Figure 4 UE 115 described or referenced Figure 11 For example, the example operations (also referred to as "blocks") of process 800 may enable UE 115 to support prioritization of event-triggered mobility reports.

[0092] In block 802, the UE may determine that the size of a first report exceeds a maximum size for transmission on a first resource. Figure 6 and Figure 7 The size of the described first report may exceed a maximum size for sending on the first resource.

[0093] In block 804, the UE may determine that the third priority of the first entry of the first report is greater than the fourth priority of the second entry of the first report. For example, entries of a first report (such as an L1 candidate cell CSI report) may be assigned priorities, and the UE may determine that entries with higher priorities are to be included in the report. The L1 candidate cell CSI report may be an example of an LTM report. As a specific example, the entries of the L1 candidate cell CSI report may be prioritized based on the value of a reported metric of the report (such as a measured RSRP value) and / or a cell ID associated with the entry of the report. In some embodiments, the base station may indicate to the UE which entries of the report should be pre-prioritized. As another example, report entries associated with different beams of the same cell may be prioritized based on the RSRP value associated with the beam.

[0094] In block 806, the UE may drop the second entry of the first report from the first report based on determining that the third priority is greater than the fourth priority. For example, the UE may drop entries from the first report in order of ascending priority until the size of the first report falls within the maximum size requirement for transmission on the first resource. Thus, based on the payload of the resource on which the report is to be transmitted (such as the payload of the PUCCH), lower priority entries may be dropped from the transmission of the report.

[0095] Figure 9 is a flow chart illustrating an example process 900 for supporting prioritization of event-triggered mobility reports in accordance with one or more aspects. The operations of process 900 may be performed by a base station (such as the one described above with reference to FIG. Figure 1 、 Figure 2 or Figure 4 Base station 105 as described or referenced above Figure 10 For example, the example operations of process 900 may enable base station 105 to support prioritization of event-triggered mobility reports.

[0096] In block 902, a second network node (such as a base station configured as a current serving cell different from a candidate serving cell) may receive a first report from a UE. The first report may be, for example, a report about Figure 6 In some embodiments, the base station may determine, based on an indicator included in the report, that the report is an event-triggered report sent based on a comparison of the priority value of the report with the priority value of another report, such as a periodic report. Thus, the base station may determine that the report is not a periodic report scheduled to be sent using the resources on which the report is sent.

[0097] In block 904, the second network node may send a handover instruction to the UE based on receiving the first report. Figure 6 The first network node described by block 602 initiates a handover procedure based on the received first report of the first network node to serve as a new serving cell for the UE.

[0119] Various modifications to the specific implementations described in this disclosure will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other specific implementations without departing from the spirit or scope of this disclosure. Therefore, the claims are not intended to be limited to the specific implementations shown herein but are to be accorded the widest scope consistent with this disclosure, the principles and novel features disclosed herein.

[0120] Additionally, one of ordinary skill in the art will readily recognize that the terms "upper" and "lower" are sometimes used for ease of describing the drawings and indicate relative positions corresponding to the orientation of the drawings on a correctly oriented page and may not reflect the correct orientation of any device as implemented.

[0121] Certain features described in this specification in the context of separate implementations may also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation may also be implemented in multiple implementations, either individually or in any suitable subcombination. Furthermore, while features may be described above as functioning in certain combinations and even initially claimed as such, one or more features from a claimed combination may in some cases be omitted from that combination, and a claimed combination may be directed to subcombinations or variations of subcombinations.

[0122] Similarly, although operations are depicted in a particular order in the accompanying drawings, this should not be understood as requiring such operations to be performed in the particular order shown or in a sequential order, or to perform all illustrated operations to achieve the desired result. In addition, the accompanying drawings may schematically depict one or more example processes in the form of flow charts. However, other operations not depicted may be incorporated into the schematically illustrated example processes. For example, one or more additional operations may be performed before, after, simultaneously with, or between any of the illustrated operations. In certain environments, multitasking and parallel processing may be advantageous.

For another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a base station. In yet other aspects of this example, the first network node, the second network node, and the third network node may be different relative to these examples. Similarly, references to a UE, a base station, an apparatus, a device, a computing system, etc., may include disclosures of the UE, base station, apparatus, device, computing system, etc. as network nodes. For example, a disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node. Consistent with the present disclosure, once a specific example is expanded upon according to the present disclosure (e.g., a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node), a broader example of the narrower example may be interpreted inversely, but in a broad, open-ended manner. In the above example where a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node, the first network node may refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first set of one or more components, or a first processing entity, etc., configured to receive information; and the second network node may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second set of one or more components, or a second processing entity, etc.

[0124] As used herein, including in the claims, the term "or" used in a list of two or more items means that any one of the listed items can be employed alone, or any combination of two or more of the listed items can be employed. For example, if a composition is described as containing component A, B, or C, the composition can include A alone; B alone; C alone; A and B combined; A and C combined; B and C combined; or A, B, and C combined. Furthermore, as used herein, including in the claims, "or" as used in a list of items beginning with "at least one of" indicates a separate list, so that, for example, a list of "at least one of A, B, or C" means A or B or C or AB or AC or BC or ABC (i.e., A and B and C) or any combination of any of these. The term "substantially" is defined as largely, but not necessarily entirely, what is specified (and includes what is specified; for example, substantially 90 degrees includes 90 degrees, and substantially parallel includes parallel), as understood by one of ordinary skill in the art. In any disclosed embodiment, the term "substantially" may be replaced with "within [percentage] of" that specified, where percentages include 0.1%, 1%, 5%, or 10%.

[0125] The previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure.
