Intelligent mechanism for frequency band selection in 5G NR

Abstract

This disclosure relates to an intelligent mechanism for frequency band selection in 5G NR, including a method and apparatus for enabling a User Equipment (UE) to perform frequency band measurements and provide a trimmed measurement report to a base station. A first connection is established between the UE and the base station, and a configuration message is received from the base station. The configuration message identifies multiple frequency bands for which the UE will provide measurement reports. The UE determines whether the aggregate bandwidth of a combination of frequency bands among the multiple frequency bands is greater than the aggregate bandwidth of the first connection, and determines whether a signal quality metric of the determined frequency band combination is greater than a predetermined threshold. In response to these determinations, the UE performs frequency band measurements on the frequency band of the frequency band combination and transmits the trimmed measurement report to the base station.

Description

Technical Field

[0001] This application relates to wireless communication, including methods, systems, and apparatus for providing measurement reports for frequency band selection by a wireless device. Background Technology

[0002] The use of wireless communication systems is growing rapidly. Furthermore, wireless communication technology has evolved from solely voice communication to also include the transmission of data such as the internet and multimedia content.

[0003] Mobile electronic devices can take the form of smartphones or tablets that users typically carry. Wearable devices (also known as accessory devices) are a newer form of mobile electronic device, an example being a smartwatch. Additionally, low-cost, low-complexity wireless devices designed for static or dynamic deployment are rapidly increasing as part of the development of the “Internet of Things”. In other words, the range of required device complexity, capabilities, traffic patterns, and other characteristics is becoming increasingly broad. Generally, there is a need to recognize and provide improved support for a wide range of required wireless communication characteristics. For example, wireless network designs are increasingly incorporating carrier aggregation (CA). During a CA communication session, a wireless device can communicate with each of the primary cell (PCell) and one or more secondary cells (SCells). Introducing multiple active cells, especially cells operating at higher frequencies, such as millimeter wave (mmW) cells, increases the risk of overheating for wireless devices. Therefore, improvements in this field are expected. Summary of the Invention

[0004] This article presents, in particular, an implementation scheme for a system, apparatus, and method for enabling user equipment (UE) to perform band measurements and provide trimmed measurement reports to a base station.

[0005] In some implementations, a first connection is established between the UE and one or more base stations. This connection can be an LTE connection with the eNB, a standalone (SA) connection with the gNB, or a non-standalone (NSA) connection with both the eNB and the gNB.

[0006] In some implementations, a configuration message is received from the base station. The configuration message may include a corresponding band identifier (ID) for each of a plurality of frequency bands for which the UE will provide measurement reports. The configuration message may also include a measurement object specifying the band ID for each of the plurality of frequency bands.

[0007] In some implementations, the UE determines whether a first aggregated bandwidth of a combination of frequency bands in multiple frequency bands is greater than a second aggregated bandwidth of a first connection. In some implementations, the UE further determines whether a signal quality metric of the determined frequency band combination is greater than a predetermined threshold. In various implementations, the signal quality metric includes the received signal to received power ratio (RSRP) and / or the signal-to-noise ratio (SNR), and both RSRP and SNR may have their own corresponding quality thresholds.

[0008] In some implementations, when it is determined that the aggregate bandwidth of the frequency band combination is greater than the aggregate bandwidth of the current connection, and further determined that the signal quality index of the frequency band combination is greater than a signal quality threshold, the UE performs frequency band measurement on the frequency band of the frequency band combination and transmits a trimmed measurement report to the base station. The trimmed measurement report includes a measurement report on the frequency band of the frequency band combination.

[0009] The technologies described herein may be implemented in or used in several different types of devices, including but not limited to cellular phones, tablets, accessories and / or wearable computing devices, portable media players, cellular base stations and other cellular network infrastructure equipment, servers, and any of a variety of other computing devices.

[0057] the term

[0058] The following is a glossary of terms used in this disclosure:

[0059] Memory media—any device of any type of nontransitory memory device or storage device. The term "memory media" is intended to include mounting media such as CD-ROMs, floppy disks, or magnetic tape devices; computer system memory or random access memory such as DRAM, DDR RAM, SRAM, EDO RAM, Rambus RAM, etc.; non-volatile memory such as flash memory, magnetic media, e.g., hard disk drives or optical storage devices; registers or other similar types of memory elements, etc. Memory media may also include other types of nontransitory memory or combinations thereof. Furthermore, memory media may reside in a first computer system executing a program, or may reside in a different second computer system connected to the first computer system via a network such as the Internet. In the latter case, the second computer system may provide program instructions to the first computer for execution. The term "memory media" may include two or more memory media that may reside in different locations on different computer systems, for example, connected via a network. Memory media may store program instructions (e.g., representing a computer program) that can be executed by one or more processors.

[0060] Carrier medium—the memory medium as described above, and physical transmission medium, such as buses, networks and / or other physical transmission media for transmitting signals (such as electrical signals, electromagnetic signals or digital signals).

[0061] Programmable hardware elements encompass a variety of hardware devices that include multiple programmable functional blocks connected via programmable interconnects. Examples include FPGAs (Field-Programmable Gate Arrays), PLDs (Programmable Logic Devices), FPOAs (Field-Programmable Object Arrays), and CPLDs (Complex PLDs). Programmable functional blocks can vary from fine-grained (combinatorial logic units or lookup tables) to coarse-grained (arithmetic logic units or processor cores). Programmable hardware elements may also be referred to as "configurable logic units."

[0062] Computer system—any of all types of computing or processing systems, including personal computer systems (PCs), mainframe computer systems, workstations, networked appliances, internet-connected appliances, personal digital assistants (PDAs), television systems, grid computing systems, or other devices or combinations thereof. In general, the term "computer system" can be broadly defined to encompass any device (or combination of devices) having at least one processor that executes instructions from a memory medium.

[0063] User equipment (UE) (or “UE device”) — any of various types of computer systems or devices that are mobile or portable and perform wireless communication. Examples of UE devices include mobile phones or smartphones (e.g., iPhone). TM Based on AndroidTM Telephones), portable gaming devices (e.g., Nintendo DS) TM PlayStation Portable TM Gameboy Advance TM iPhone TM Wearable devices (e.g., smartwatches, smart glasses), laptops, PDAs, portable networking devices, music players, data storage devices, or other handheld devices. Generally, the term "UE" or "UE device" can be broadly defined as any electronic, computing, and / or telecommunications equipment (or combination of equipment) that is easily transportable by the user and capable of wireless communication.

[0064] A wireless device is any of various types of computer systems or devices that perform wireless communication. A wireless device can be portable (or mobile), or it can be stationary or fixed in a location. A UE is an example of a wireless device.

[0065] A communication device is any of various types of computer systems or devices that perform communication, which may be wired or wireless. A communication device may be portable (or mobile), or it may be stationary or fixed in a location. A wireless device is one example of a communication device. A UE is another example of a communication device.

[0066] Base station—The term “base station” has the full range of its common meaning and includes at least a wireless communication station that is installed in a fixed location and is used for communication as part of a wireless telephone system or radio system.

[0067] Processing element—refers to various elements or combinations of elements. Processing elements include, for example, circuits such as ASICs (Application-Specific Integrated Circuits), portions or circuits of individual processor cores, the entire processor core, individual processors, programmable hardware devices (such as field-programmable gate arrays (FPGAs)), and / or a large portion of a system comprising multiple processors.

[0068] A channel is a medium used to transmit information from a transmitter to a receiver. It should be noted that because the characteristics of the term "channel" can vary depending on different wireless protocols, the term "channel" as used herein can be considered to be used in a standard manner consistent with the type of device to which the term is referenced. In some standards, the channel width can be variable (e.g., depending on device capabilities, frequency band conditions, etc.). For example, LTE can support scalable channel bandwidths from 1.4 MHz to 20 MHz. In contrast, WLAN channels can be 22 MHz wide, while Bluetooth channels can be 1 MHz wide. Other protocols and standards may include different definitions of channels. Furthermore, some standards may define and use multiple types of channels, such as different channels for uplink or downlink and / or different channels for different purposes such as data, control information, etc.

[0069] Frequency band—The term “frequency band” has the full range of its general meaning and includes at least a segment of spectrum (e.g., radio frequency spectrum) in which channels are used or reserved for the same purpose.

[0070] Automatic—means an action or operation performed by a computer system (e.g., software executed by the computer system) or device (e.g., circuits, programmable hardware elements, ASICs, etc.) without requiring direct user input to specify or perform that action or operation. Therefore, the term "automatically" is the opposite of an operation performed or specified manually by a user, where the user provides input to directly perform the operation. An automatic process can be initiated by user-provided input, but the subsequent actions performed "automatically" are not specified by the user; that is, they are not performed "manually," where the user specifies each action to be performed. For example, a user filling out a form by selecting each field and providing input specifying information (e.g., by typing information, selecting a checkbox, radio selection, etc.) is considered manually filling out the form, even though the computer system must update the form in response to the user's actions. The form can be automatically filled out by a computer system (e.g., software executed on the computer system) which analyzes the fields of the form and fills it out without any user input specifying answers for the fields. As indicated above, the user can invoke the automatic filling of the form but does not participate in the actual filling of the form (e.g., the user does not manually specify answers for the fields, but they are completed automatically). This manual provides various examples of operations that are automatically performed in response to actions taken by the user.

[0071] "Configured as"—Various components can be described as being "configured as" to perform one or more tasks. In such contexts, "configured as" is a broad expression generally meaning "having" a "structure" that performs one or more tasks during operation. Thus, a component can be configured to perform a task even when it is not currently performing one (e.g., a set of electrical conductors can be configured to electrically connect one module to another, even when the two modules are not connected). In some contexts, "configured as" can also be a broad expression generally meaning a structure that "has" a "circuit" that performs one or more tasks during operation. Thus, a component can be configured to perform a task even when it is not currently powered on. Typically, the circuit forming the structure corresponding to "configured as" can include hardware circuitry.

[0072] For ease of description, various components may be described as performing one or more tasks. Such descriptions shall be interpreted as including the phrase “configured to”. The statement that a component is configured to perform one or more tasks is expressly intended not to invoke the interpretation of paragraph 6 of section 112 of title 35 of the United States Code.

[0073] Figures 1 to 2 —Communication System

[0074] Figure 1 Exemplary (and simplified) wireless communication systems that can implement various aspects of this disclosure according to some embodiments are shown. For example, Figure 1 Any or all of the wireless devices shown can be configured to perform signal detection as described herein, for example, according to one or more of the methods described herein. It should be noted that... Figure 1 The system described is merely one example of a possible system, and this implementation can be carried out in any of a variety of systems as needed.

[0075] As shown in the figure, the exemplary wireless communication system includes a base station 102A, which communicates with one or more user equipments 106A, 106B, etc., to user equipment 106N via a transmission medium. Each user equipment may be referred to herein as a "user equipment" (UE). Therefore, user equipment 106 is referred to as a UE or UE device.

[0076] Base station 102A may be a transceiver base station (BTS) or a cell site, and may include hardware and / or software to enable wireless communication with UEs 106A to 106N. Base station 102A may also be equipped to communicate with network 100 (e.g., in various possibilities, the core network of a cellular service provider, telecommunications networks such as the Public Switched Telephone Network (PSTN), and / or the Internet). Therefore, base station 102A facilitates communication between user equipments and / or between user equipments and network 100.

[0077] The communication area (or coverage area) of a base station can be referred to as a "cell". Base station 102A and UE 106 can be configured to communicate using the transmission medium of any of the various radio access technologies (RATs), which are also known as wireless communication technologies or telecommunications standards, such as GSM, UMTS (WCDMA, TD-SCDMA), LTE, LTE-A Advanced, 5G NR, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), Wi-Fi, WiMAX, etc.

[0078] Base station 102A and other similar base stations (such as base stations 102B...102N) operating according to the same or different cellular communication standards can therefore be provided as a network of cells that can provide continuous or nearly continuous overlapping services to UE 106A-106N and similar devices over a geographical area via one or more cellular communication standards.

[0079] Therefore, although base station 102A can act as such Figure 1 The diagram shows the "serving cell" of UEs 106A-106N, but each UE 106 may also be able to receive signals (and possibly within its communication range) from one or more other cells (which may be provided by base stations 102B-102N and / or any other base stations), which may be referred to as "neighboring cells". Such cells may also facilitate communication between user equipments and / or between user equipments and network 100. Such cells may include "macro" cells, "micro" cells, "pecimen" cells, and / or any other cells of various other granularities providing service area size. For example, in Figure 1 Base stations 102A to 102B shown can be macro cells, while base station 102N can be a micro cell. Other configurations are also possible.

[0080] It should be noted that UE 106 can communicate using multiple wireless communication standards. For example, UE 106 can be configured to communicate using two or more of the following: GSM, UMTS, CDMA2000, WiMAX, LTE, LTE-A, 5GNR, WLAN, Bluetooth, one or more Global Navigation Satellite Systems (GNSS, such as GPS or GLONASS), and one or more mobile television broadcasting standards (e.g., ATSC-M / H or DVB-H). Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.

[0081] Figure 2User equipment 106 (e.g., one of devices 106A to 106N) communicating with base station 102 (e.g., one of base stations 102A to 102N) according to some embodiments is shown. UE 106 may be a device with cellular communication capabilities, such as a mobile phone, handheld device, wearable device, computer, or tablet, or substantially any type of wireless device.

[0082] UE 106 may include a processor configured to execute program instructions stored in memory. UE 106 may execute any of the method embodiments of the present invention by executing such stored instructions. Alternatively or additionally, UE 106 may include programmable hardware elements, such as a field-programmable gate array (FPGA) configured to execute any of the method embodiments of the present invention or any portion thereof.

[0083] As described above, UE 106 can be configured to communicate using any of the multiple RATs. For example, UE 106 can be configured to communicate using two or more of GSM, CDMA2000, UMTS, LTE, LTE-A, NR, WLAN, or GNSS. Other combinations of wireless communication technologies are also possible.

[0084] UE 106 may include one or more antennas for communicating using one or more wireless communication protocols or technologies. In one embodiment, UE 106 may be configured to communicate using either CDMA2000 (1xRTT / 1xEV-DO / HRPD / eHRPD) or LTE and / or GSM or LTE using a single shared radio component. The shared radio component may be coupled to a single antenna or may be coupled to multiple antennas (e.g., for multiple-input multiple-output (MIMO) communication) for performing wireless communication. Typically, the radio component may include any combination of baseband processor, analog radio frequency (RF) signal processing circuitry (e.g., including filters, mixers, oscillators, amplifiers, etc.) or digital processing circuitry (e.g., for digital modulation and other digital processing). Similarly, the radio component may use the aforementioned hardware to implement one or more receive chains and transmit chains. For example, UE 106 may share one or more portions of the receive chain and / or transmit chain among various wireless communication technologies such as those discussed above.

[0085] In some implementations, UE 106 may include separate transmission and / or reception chains (e.g., including separate RF components and / or digital radio components) for each wireless communication protocol configured to communicate therewith. As another possibility, UE 106 may include one or more radio components shared among multiple wireless communication protocols, as well as one or more radio components uniquely used by a single wireless communication protocol. For example, UE 106 may include shared radio components for communicating using either LTE or 1xRTT (or LTE or GSM), and separate radio components for communicating using each of Wi-Fi and Bluetooth. Other configurations are also possible.

[0086] UE 106 and / or BS 102 can be configured to perform carrier aggregation (CA). For example, BS 102 can use any combination of carriers communicating with UE 106 using RAT. As a possibility, UE 106 and BS 102 can employ Licensed Assisted Access (LAA) technology, and thus can aggregate licensed and unlicensed spectrum for communication. According to various implementations, carrier aggregation can employ a primary cell (PCell) and one or more secondary cells (SCells), which can be co-located within a single base station tower, or distributed across a first BS and one or more neighboring BSs.

[0087] Figure 3 —Block diagram of UE device

[0088] Figure 3 A possible block diagram of UE device 106 is shown. As shown, UE device 106 may include a system-on-a-chip (SOC) 300, which may include components for various purposes. For example, as shown, SOC 300 may include a processor 302 and display circuitry 304, the processor executing program instructions for UE device 106, and the display circuitry performing graphics processing and providing display signals to display 360. SOC 300 may also include motion sensing circuitry 370, which may detect motion of UE 106, for example, using a gyroscope, accelerometer, and / or any of various other motion sensing components. One or more processors 302 may also be coupled to a memory management unit (MMU) 340, which may be configured to receive addresses from one or more processors 302 and translate these addresses into locations in memory (e.g., memory 306, read-only memory (ROM) 350, flash memory 310). MMU 340 may be configured to perform memory protection and page table translation or setup. In some implementations, the MMU 340 may be included as part of the processor 302.

[0089] As shown in the figure, the SOC 300 can be coupled to various other circuits of the UE 106. For example, the UE 106 may include various types of memory (e.g., including NAND flash memory 310), connector interface 320 (e.g., for coupling to computer systems, docking stations, charging stations, etc.), display 360, and wireless communication circuitry 330 (e.g., for LTE, LTE-A, NR, CDMA2000, Bluetooth, Wi-Fi, NFC, GPS, etc.).

[0090] UE device 106 may include at least one antenna, and in some embodiments, may include multiple antennas 335a and 335b (and / or other additional antennas) for performing wireless communication with a base station and / or other devices. For example, UE device 106 may use antennas 335a and 335b to perform wireless communication. As described above, UE device 106 may be configured in some embodiments to perform wireless communication using multiple wireless communication standards or radio access technologies (RATs).

[0091] The wireless communication circuitry 330 may include a Wi-Fi logic component 332, a cellular modem 334, and a Bluetooth logic component 336. The Wi-Fi logic component 332 enables the UE device 106 to perform Wi-Fi communication over an 802.11 network. The Bluetooth logic component 336 enables the UE device 106 to perform Bluetooth communication. The cellular modem 334 may be a low-power cellular modem capable of performing cellular communication according to one or more cellular communication technologies (e.g., LTE, 5G NR, GSM, etc.).

[0092] As described herein, UE 106 may include hardware and software components for implementing embodiments of this disclosure. For example, one or more components of the wireless communication circuitry 330 (e.g., cellular modem 334) of UE device 106 may be configured to implement some or all of the methods described herein, for example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable storage medium), a processor configured as an FPGA (Field Programmable Gate Array), and / or using dedicated hardware components that may include ASICs (Application-Specific Integrated Circuits).

[0093] Figure 4 —Block diagram of a base station (BS)

[0094] Figure 4 An exemplary block diagram of a base station 102 according to some embodiments is shown. It should be noted that... Figure 4The base station shown is merely one example of a possible base station. As illustrated, base station 102 may include a processor 404 capable of executing program instructions specific to base station 102. Processor 404 may also be coupled to a memory management unit (MMU) 440 or other circuitry or device, which may be configured to receive addresses from processor 404 and translate those addresses into locations in memory (e.g., memory 460 and read-only memory (ROM) 450).

[0095] Base station 102 may include at least one network port 470. This network port 470 may be configured to be coupled to a telephone network and provide access rights as described above. Figure 1 and Figure 2 The telephone network described herein includes multiple devices such as UE device 106.

[0096] Network port 470 (or an additional network port) may also be configured, or alternatively configured, to be coupled to a cellular network, such as the core network of a cellular service provider. The core network may provide mobility-related services and / or other services to multiple devices, such as UE device 106. In some cases, network port 470 may be coupled to a telephone network via the core network, and / or the core network may provide the telephone network (e.g., in other UE devices served by the cellular service provider).

[0097] Base station 102 may include at least one antenna 434 and possibly multiple antennas. Antenna 434 may be configured to operate as a wireless transceiver and may be further configured to communicate with UE device 106 via radio component 430 (or multiple radio components 430). Antenna 434 communicates with radio component 430 via communication link 432. Communication link 432 may be a receive link, a transmit link, or both. Radio component 430 may be configured to communicate via various wireless communication standards, including but not limited to LTE, LTE-A, NR, GSM, UMTS, CDMA2000, Wi-Fi, etc.

[0098] Base station 102 can be configured to perform wireless communication using multiple wireless communication standards. In some cases, base station 102 may include multiple radios that enable base station 102 to communicate according to multiple wireless communication technologies. For example, as one possibility, base station 102 may include an LTE radio for performing communication according to LTE and a Wi-Fi radio for performing communication according to Wi-Fi. In such cases, base station 102 may be able to operate as both an LTE base station and a Wi-Fi access point. As another possibility, base station 102 may include a multimode radio component capable of performing communication according to any of multiple wireless communication technologies (e.g., LTE and Wi-Fi, LTE and UMTS, LTE and CDMA2000, LTE and 5G NR, UMTS and GSM, etc.). BS 102 may provide one or more communication technologies and / or one or more cells of one or more Public Land Mobile Networks (PLMNs). According to some embodiments, BS 102 may provide multiple cells that can be organized, grouped, or configured into one or more cell sets. According to some embodiments, the one or more cell sets provided by BS 102 may also include cells provided by one or more additional base stations.

[0099] As further described herein, base station 102 may include hardware and software components for implementing or supporting specific implementations of the features described herein. Processor 404 of base station 102 may be configured to implement or support some or all of the methods described herein, for example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium). Alternatively, processor 404 may be configured as a programmable hardware element such as a FPGA (Field-Programmable Gate Array), or as an ASIC (Application-Specific Integrated Circuit), or a combination thereof. Alternatively (or in addition), in conjunction with one or more of other components 430, 432, 434, 440, 450, 460, and 470, processor 404 of base station 102 may be configured to implement or support some or all of the features described herein. BS 102 may be configured to perform carrier aggregation (CA).

[0100] Depending on the implementation scheme, BS 102 can be an eNodeB (eNB) or a gNodeB (gNB).

[0101] Figures 5A to 5B —ENDC and standalone deployment

[0102] In some implementations, the UE can operate in areas with Evolved Universal Terrestrial Radio Access (EUTRA) New Radio Interface (NR) Dual Connectivity (ENDC) deployments, where the UE is connected to both an NR gNB and an LTE eNB in ​​a non-standalone (NSA) deployment, and where both the gNB and eNB are connected to the Evolved Packet Core (EPC), such as... Figure 5A As shown. Alternatively, the UE device can operate in areas with NR standalone (SA) deployments, such as... Figure 5B As shown, the UE connects to the Next Generation Integrated Network (NGCN) via a gNB. Alternatively, the UE can connect to the EPC via an eNB using an LTE connection. Implementations described herein depict various methods and devices for providing measurement reports and performing cell selection in these and other environments.

[0103] Carrier aggregation

[0104] 5G New Radio (NR) and LTE, as well as other wireless networks, may include carrier aggregation (CA), enabling user equipment (UE), such as UE 106, to communicate with multiple cells on a single bandwidth to improve overall throughput. CA technology allows for increased throughput or performance by efficiently utilizing spectrum / frequency resources available to the network.

[0105] Generally, a UE can establish a connection to the network via a primary cell (PCell) and subsequently establish auxiliary connections with one or more secondary cells (SCells) to improve throughput. Depending on various implementations, the PCell and one or more SCells can be co-located, or they can be instantiated as separate base stations. Depending on various implementations, the PCell and one or more SCells can operate under the same RAT (e.g., 5G NR) or different RATs (e.g., LTE and 5G NR). In an exemplary implementation, the PCell is an LTE cell (such as an eNB) called a primary cell group (MCG) that acts as the anchor cell and establishes initial signaling thereon, while the SCell is a 5G NR cell (such as a gNB) called a secondary cell group (SCG). After the UE is attached to a PCell, 5G SCells can be added blindly or based on 5G cell measurements of the UE. Data can then be transferred according to the configuration on top of the 5G cell. This configuration can be referred to as a non-standalone (NSA) configuration with an LTE anchor, and... Figure 5A It is shown schematically in the middle.

[0106] Different UEs may have different capabilities regarding CA (Carrier Response). For example, some UEs may be able to perform CA with certain combinations of frequency ranges, but not with other combinations. Similarly, different cells, different regions, or different networks may use various combinations of frequency ranges for CA. For example, a given PLMN may have permission to use frequency ranges in one region that differ from those in another region. Each of the PCell and one or more SCells may communicate with the UE using one or more corresponding frequency bands. In some implementations, one or more of these frequency bands may be measured by the UE, and the UE may provide corresponding measurement reports to the base station.

[0107] 5G New Radio (5G NR) is designed to support a variety of use cases, including those requiring high reliability and low latency (URLLC—round-trip latency tolerance of 1ms), enhanced mobile broadband (eMBB—downlink throughput of approximately 20Gbps), and massive Internet of Things (MIOT—supporting thousands of devices in a single cell), among others.

[0108] In some implementations, the sub-6 GHz frequency range (Sub6) and the millimeter-wave frequency range (mmW) can be deployed by one or more gNBs. For mmW deployments, the bandwidth can be significantly larger than that used for the sub-6 GHz frequency range (e.g., mmW bandwidth could be 50 MHz, 100 MHz, 200 MHz, or 400 MHz, etc.). The Sub6 range is sometimes referred to as "FR1," while the mmW range is sometimes referred to as "FR2." In some implementations, the UE may need to utilize special radio frequency (RF) modules to be able to scan and / or measure these wider bandwidths, potentially consuming more power than scanning and / or measuring via LTE or Sub6. Therefore, battery consumption can increase when using 5G mmW. Additionally, power consumption can be higher for beam management because more components in these RF modules are active.

[0109] Field deployments for both Sub-6 and mmW frequencies of NR are expected to have overlapping coverage. In these implementations, if battery power falls below a certain threshold of remaining battery life, the UE may want to conserve battery power and intelligently make measurement reporting decisions that could trigger the network to add NR cells.

[0110] For non-standalone (NSA) ENDC deployments, as the device heats up during active data sessions, some implementations described herein describe steps that can be taken to control the heat and thus avoid undervoltage conditions. In previously implemented radio access technologies (RATs), an active session may involve only one technology, such as LTE or WCDMA. In contrast, ENDC deployments may involve simultaneously using LTE and 5G modems for a single data session of a UE. Therefore, it may be desirable to evaluate data for each technology and make intelligent decisions to identify where and when modem power can be compensated to mitigate heating without adversely affecting the data session or user experience.

[0111] Frequency band measurement report

[0112] In cellular deployments with multiple NR bands (e.g., FR1 and FR2 bands), different bandwidth configurations and carrier components can be used for the UE. In the current specific implementation, the network (NW) can configure a measurement object and provide it to the UE, indicating multiple bands for which the UE will perform measurements and provide measurement reports. Band measurements can be one of various types of measurements, including but not limited to signal quality metrics (e.g., Signal-to-Interference-plus-Noise Ratio (SINR), Received Signal Strength Indicator (RSSI), Received Signal Received Quality (RSRQ), or Reference Signal Received Power (RSRP) measurements), inter-band and / or intra-band measurements, and / or beam measurements, etc. The UE can perform the indicated band measurements, provide a measurement report for the indicated band, and the NW can configure a connection with the UE on a first-come, first-served basis based on the measurement reports.

[0113] The NW can send a Radio Resource Control (RRC) reconfiguration message that adds one of the first NR bands reported by the UE, without offering the UE the option to pre-allocate on a specific requested NR band. These implementations can lead to lower throughput and a poorer user experience. For example, when the NW configures measurement IDs for both FR1 and FR2 bands and the UE sends a measurement report for FR1, the NW can configure the FR1 band. This can result in lower throughput when FR2 has multiple carrier components with higher bandwidth. In areas where only the FR1 band is available, or where multiple bands / bandwidths are available, the NW can configure a low-bandwidth NR band when the UE sends a measurement report for a low-bandwidth FR1 cell, leading to a poorer user experience.

[0114] To address these and other issues, the implementation scheme described herein presents methods and apparatus for a UE to perform intelligent measurement reporting and band selection based on radio frequency (RF) conditions, available NR component carrier aggregation conditions, total NR aggregation bandwidth of different band combinations, and / or the UE's current temperature. This can assist the UE in saving power by measuring a limited number of NR bands based on specific criteria.

[0115] Figures 6A to 6B -Flowcharts for measurement reports

[0116] Figures 6A to 6B This is a flowchart illustrating a method for providing trimmed measurement reports by a UE, based on some implementation schemes. Figure 6A The capital letters AF circled at the bottom are intended to connect to Figure 6B The corresponding letter at the top.

[0117] At position 602, the UE pre-claims and establishes a connection on the cell, which can be standalone (SA), non-standalone (NSA), or an LTE connection, etc. During connection establishment, the UE can obtain information about the serving cell, such as the unique cell identifier (ID), global cell identifier (GCI), and / or bandwidth information.

[0118] At 604, the network configuration specifies the measurement object to be provided to the UE, which includes a measurement identifier (ID) for one or more NR bands for which the UE will perform measurements and report measurements. The measurement object can specify specific NR bands and / or combinations of bands that can be used to connect with the UE. The measurement object is then transmitted to the UE.

[0119] At point 606, the UE determines whether its connected radio access technology (RAT) has changed (e.g., from LTE to NR or vice versa, from SA to NSA or vice versa) more than a predetermined number of times (e.g., more than twice) within a predetermined time period (e.g., within the last 5, 10, or 15 seconds). Source delay measurement (SDM) triggers can be excluded from this determination; that is, SDM triggers may not be eligible to change the RAT for the purpose of this determination.

[0120] At step 608, in response to determining that the UE's connected RAT has changed more than a predetermined number of times within a predetermined time period, the UE can suppress measurement reports to avoid further ping-ponging between RATs. In other words, at step 604, the UE can avoid taking any action in response to receiving a measurement object from the network.

[0121] At step 610, in response to determining that the UE's connection RAT has not changed more than a predetermined number of times within a predetermined time period, the UE may determine whether the aggregate bandwidth (BW) of any combination of frequency bands indicated in the measurement object is greater than the current aggregate BW of the connection established with the base station (i.e., the connection established at step 602). The frequency band combination may include one or both of LTE and NR frequency bands, and may include combinations of FR1 and / or FR2 frequency bands. The UE may determine the available frequency band combinations and / or the bandwidth of the frequency bands indicated by the measurement report (MR) based on a fingerprint database stored in the UE's memory. In some embodiments, the fingerprint database may be obtained by the UE from a cloud service, and / or may be downloaded by the UE in a timely manner when the fingerprint database is attached to the WLAN. The fingerprint database may be specific to a particular service area, such that the fingerprint database includes frequency band combinations and bandwidth information related to active frequency bands in a particular cell. For example, the fingerprint database may be associated with a unique cell ID received by the UE when the connection is established at step 602.

[0122] At 624, in response to determining that the aggregate bandwidth of none of the available frequency band combinations is greater than the current aggregate bandwidth of the connection between the UE and the base station, the UE can determine whether the current radio frequency (RF) conditions are better than a threshold. For example, the UE can determine whether its current connection has a received signal-to-receive power (RSRP) ratio less than a first threshold and / or a signal-to-noise ratio (SNR) less than a second threshold. If the RSRP and / or SNR are not less than their respective thresholds, then at 618, the UE can suppress all measurement reports and maintain its current connection on one or more of its serving cells.

[0123] At 612, in response to determining at 610 that the aggregated BW of the available frequency band combination is greater than the aggregated BW of the current connection, or at 624 that the RSRP and / or SNR of the current connection is less than a threshold, the UE can determine whether any available FR2 frequency band indicated in the measurement object exists.

[0124] At 616, in response to determining that no available FR2 bands exist, the UE may perform band measurements and transmit a trimmed measurement report to the base station for available band combinations that also have the highest aggregated band width (BW) with RSRP and / or SNR greater than the corresponding threshold. The UE may utilize a fingerprint database to determine which band combination has the highest aggregated BW. The trimmed measurement report may include measurements of this band combination, but may omit measurements of one or more other bands indicated in the measurement object received from the NW. If none of the available bands meet the criteria of step 616, the method may proceed to steps 642 and 638, as described below.

[0125] At 632, the count can be incremented after sending the revised measurement report. At 634, it is determined whether the count exceeds a predetermined threshold. In response to determining that the count has not exceeded the threshold, the UE can determine at 636 whether an NR connection has been established with the frequency band combination indicated in the measurement report. If a connection has been established, the method can terminate at step 660. If a connection has not been established, the UE can remeasure and resend the measurement report at step 616.

[0126] At point 638, in response to determining that the count exceeds a threshold, the UE can measure all frequency bands indicated by the measurement object and send a complete (i.e., untrimmed) measurement report to the base station for all frequency bands indicated in the measurement object. The network can then continue to establish a connection with the UE based on the received complete measurement report.

[0127] Returning to step 612, if it is determined that there is an available FR2 band as indicated in the measurement object, then the UE can continue to determine at 644 whether the temperature of the UE (e.g., surface temperature, modem temperature, etc.) is less than a threshold.

[0128] At point 646, based on the determination that the UE's temperature is below a threshold, the UE can perform band measurements for the available band combination and send a trimmed measurement report. This available band combination includes one or more FR2 bands among all available band combinations that have the highest aggregate bandwidth and further have RSRP and / or SNR exceeding the corresponding threshold. The UE can determine which band combination to measure and report by utilizing a fingerprint database. At point 656, if none of the available bands meet the criteria of step 646, then the UE can perform measurements for all available bands and send a complete measurement report to the network.

[0129] At step 648, after sending the trimmed measurement report, the UE can increment the count at step 650 and check if the count exceeds a threshold. If the threshold is not exceeded, the UE checks at step 652 whether a connection has been established using the frequency band combination indicated in the trimmed measurement report. If a connection has been established, the method terminates at step 658. If a connection has not been established, the UE remeasures and resends the trimmed measurement report at step 646.

[0130] At step 660, in response to determining that the UE temperature is not less than (i.e., greater than) a threshold, the UE performs band measurement only for a single component carrier in the FR1 or FR2 band that meets the signal strength criteria (i.e., has an RSRP and / or SNR greater than the corresponding threshold) and sends a trimmed measurement report. The UE can determine which component carrier to use based on a fingerprint database (e.g., selecting the component carrier with the highest BW). If no band is available to meet the criteria of step 660, the UE can remain on its current serving cell and avoid performing band measurement and reporting.

[0131] At 630, the count can be incremented after sending the revised measurement report. At 626, it is determined whether the count exceeds a predetermined threshold. In response to determining that the count has not exceeded the threshold, the UE can determine at 628 whether an NR connection has been established with the frequency band combination indicated in the measurement report. If a connection has been established, the method can terminate at step 622. If a connection has not been established, the UE can remeasure and resend the measurement report at step 660.

[0132] At 626, in response to determining that the count exceeds a threshold, the UE can measure all frequency bands indicated by the measurement object and, at step 620, send a complete (i.e., untrimmed) measurement report for all frequency bands indicated in the measurement object. The network can then continue to establish a connection with the UE based on the received complete measurement report.

[0133] Figure 7 - Flowcharts for refining measurement reports

[0134] Figure 7 This is a flowchart illustrating a method for performing selective band measurements and measurement reports, based on some implementation schemes. Figure 7 Aspects of the method may be implemented by a wireless device, such as one or more UEs 106, which communicates with one or more base stations (e.g., BS 102) as shown in the accompanying drawings and as described with respect to the drawings, or more generally, as needed, in conjunction with any of the computer systems or devices shown in the drawings, as well as other circuits, systems, devices, elements or components shown in the drawings and other devices. For example, one or more processors (or processing elements) of the UE (e.g., one or more processors 302, one or more baseband processors, one or more processors associated with communication circuitry (e.g., 330), etc.) may cause the UE to perform some or all of the method elements shown. Similarly, one or more processors 404, one or more baseband processors, one or more processors associated with communication circuitry (e.g., 430, 432), etc., may cause the BS to perform some or all of the method elements shown.

[0135] refer to Figure 7 The described methods and steps may be partially similar to those in the reference. Figures 6A to 6B The flowchart shown illustrates some of the method steps in the method process. Within the scope of this disclosure, it is considered that... Figures 6A to 6B Any part of the description may be referenced as appropriate. Figure 7 The methods described are used in combination.

[0136] In various implementation schemes, some of the method elements shown may be executed simultaneously in a different order than those shown, may be replaced by other method elements, or may be omitted. Additional method elements may also be executed as needed. As shown in the figure, the method can operate as follows.

[0137] At point 702, a first connection is established with the base station. This connection can be an LTE connection with the eNB, a standalone (SA) connection with the gNB, or a non-standalone (NSA) connection with both the eNB and gNB. In various implementations, for an NSA connection, "base station" can refer to either the eNB or the gNB.

[0138] At position 704, a configuration message is received from the base station. The configuration message includes a corresponding band identifier (ID) for each of the multiple frequency bands for which the UE will provide measurement reports. The configuration message may include a measurement object specifying the band ID for each of the multiple frequency bands.

[0139] At step 706, the UE determines whether a first aggregated bandwidth of a band combination among multiple frequency bands is greater than a second aggregated bandwidth of the first connection. The band combination may include a single frequency band or multiple frequency bands. For example, the band combination may be an Evolved Universal Terrestrial Radio Access New Radio (E-UTRA NR) dual connectivity (ENDC) connection, or it may be another type of band combination utilizing carrier aggregation and multiple frequency bands. In some embodiments, the UE determines whether the aggregated bandwidth of the band combination is greater than the aggregated bandwidth of the first connection by utilizing a fingerprint database stored on a storage medium. The fingerprint database may include band combination and bandwidth information for multiple frequency bands. The band combination may specify multiple different combinations of frequency bands that can be used by the UE to establish a connection, while the bandwidth information may specify the bandwidth of each of the multiple frequency bands. The fingerprint database may contain cell IDs corresponding to the cell ID associated with the first connection. The UE may tag each band combination whose aggregated bandwidth is greater than the aggregated bandwidth of the first connection, and may subsequently determine the signal quality metrics of one or more of these band combinations in step 708.

[0140] At 708, it is determined whether the signal quality metric of the determined band combination is greater than a predetermined threshold. In various implementations, the signal quality metric includes the received signal-to-receive-power (RSRP) ratio and / or the signal-to-noise ratio (SNR), and each of the RSRP and SNR may have its own corresponding quality threshold. The UE may first determine whether the band combination with the largest aggregate bandwidth has a signal quality metric exceeding the quality threshold. When the band combination includes multiple bands, the UE may check whether each of the multiple bands meets the signal quality metric. If the signal quality metric of this band combination exceeds the quality threshold, then this band combination can be selected for measurement reporting, as described below at step 710. Alternatively, if this band combination does not have sufficiently high signal quality, then the UE may continue to determine whether the band combination with the second highest aggregate bandwidth (from the case where the aggregate bandwidth of the band combination is greater than the aggregate bandwidth of the currently connected band) meets the signal quality threshold, and so on.

[0141] At point 710, when it is determined that the aggregate bandwidth of the frequency band combination is greater than the aggregate bandwidth of the current connection, and further determined that the signal quality metric of the frequency band combination is greater than the signal quality threshold, the UE performs frequency band measurements on the frequency bands of the frequency band combination and transmits a trimmed measurement report to the base station. The trimmed measurement report includes a measurement report on the frequency bands of the frequency band combination. In some implementations, even if no available frequency band combination with an aggregate bandwidth greater than the current aggregate bandwidth is determined, if it is further determined that the current connection does not meet the signal quality metric (i.e., if the signal quality of the first connection is below the threshold), the UE may also perform frequency band measurements and provide a trimmed measurement report for the available frequency band combination with the highest aggregate bandwidth and / or sufficiently high signal quality (i.e., exceeding the signal quality threshold). If it is determined that no available frequency band combination simultaneously contains sufficiently high aggregate bandwidth and sufficiently high signal quality, the UE may continue to perform frequency band measurements on all frequency bands indicated in the configuration message and transmit a complete measurement report for each of the multiple frequency bands to the base station.

[0142] In some implementations, it is determined that a second connection is not established using the frequency band combination associated with the revised measurement report after it has been transmitted to the base station. In these cases, the UE may retransmit the revised measurement report to the base station a predetermined number of times. If a second connection is not established using this frequency band combination after the revised measurement report has been retransmitted to the base station a predetermined number of times, the UE may transmit a complete measurement report to the base station, wherein the complete measurement report includes measurement reports for each of the multiple frequency bands identified in the configuration message received from the base station. In other words, if a connection is not established for the measured and reported frequency band combination after a predetermined number of attempts, the UE may provide a complete measurement report for all frequency bands indicated by the measurement object to assist in establishing a connection.

[0143] In some implementations, it can be determined that the UE has changed between connections more than a threshold number of times within a predetermined time period. In these cases, the UE can avoid providing trimmed measurement reports to the base station to avoid excessive round-trip transmissions between connections. For example, if the UE has changed between connections twice (e.g., between SA and NSA connections) within the previous 10 seconds when it receives the configuration message (or more generally, if it has changed between connections X or more times in the previous Y seconds), then the UE can avoid performing any band measurements and transmitting measurement reports in response to receiving the configuration message from the base station.

[0144] In some implementations, the frequency band combination is determined to include the FR2 band. In response to determining that the frequency band combination includes the FR2 band, the UE can determine whether the UE's temperature exceeds a temperature threshold. When the temperature does exceed the temperature threshold, the UE can transmit a revised measurement report including a measurement report of only one component carrier of the frequency band combination. Alternatively, when the temperature does not exceed the temperature threshold, the revised measurement report can include measurements of all component carriers of the frequency band combination.

[0145] In addition to the exemplary embodiments described above, further embodiments of this disclosure may be implemented in any of a variety of forms. For example, some embodiments may be implemented as computer-implemented methods, computer-readable storage media, or computer systems.

The network device may be implemented in any of a variety of forms.
