Each of the foregoing applications is assigned to the assignee of this application. Technical Field

[0003] The following discussion pertains to wireless communications, including Quality of Experience (QoE) measurement and reporting. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE), LTE-A, or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each supporting communication for multiple communication devices simultaneously, which may be referred to as User Equipment (UE).

[0005] In some wireless communication systems, a UE can be configured with a Quality of Experience (QoE) measurement configuration. The UE can use this configuration to measure the QoE metric of the service being utilized by the UE and report the QoE measurement to the base station. The base station can relay the QoE measurement to a QoE server. The QoE server can perform or instruct the base station to make adjustments to parameters associated with the service to improve the QoE associated with that service. Conventional techniques used for measuring and reporting QoE measurements can be improved. Summary of the Invention

In some cases, the described technology can provide real-time QoE reporting between the UE, the base station, and (in some cases) a QoE server. Furthermore, the described technology can provide QoE measurements readable by different types of cells in a disaggregated base station (e.g., a base station with a central unit (CU) and distributed unit (DU) split). For example, the UE can receive a configuration message including a first configuration for reporting QoE measurements to the base station and a second configuration for reporting QoE measurements to the QoE server. The UE can measure one or more QoE metrics according to the configuration message and generate a first report for the base station based on the QoE measurements and the first configuration. After generating the report, the UE can send at least the first report to the base station according to the first configuration.

[0064] Figures 14 to 17 A flowchart illustrating a method for supporting QoE measurement and reporting is shown in accordance with aspects of this disclosure. Detailed Implementation

[0065] In some wireless communication systems, User Equipment (UE) can be configured to measure Quality of Experience (QoE) metrics and report QoE measurements to a base station, which can relay these measurements to a QoE server. QoE measurements indicate how the UE is experiencing applications served by the base station, such as streaming, chat, and video applications. Based on these QoE measurements, the QoE server can determine whether adjustments associated with the application should be made by the QoE server, the base station, or both to improve the quality of experience for the UE when using the application. In conventional QoE measurement and reporting, the QoE reports that the UE can send to the base station may be in a configuration unreadable by the base station. In this case, the base station must relay the QoE reports to the QoE server and await instructions from the QoE server regarding adjustments to be made to optimize the QoE associated with the application. Furthermore, QoE measurement and reporting may not be supported by decomposed base stations (e.g., base stations split into a central unit (CU) and at least one distributed unit (DU), which may adversely affect the ability of the CU or DU to optimize their functionality separately. For example, a DU might not be able to perform Media Access Control (MAC) scheduling, beam management, etc., based on QoE reports, and might not be able to optimize application performance based on radio conditions. Furthermore, since current QoE configuration and reporting are based on Radio Resource Control (RRC), only non-real-time QoE optimization is possible. Because optimization opportunities are limited, these conventional techniques used for QoE measurement and reporting can adversely affect network reliability and efficiency.

[0066] To improve network performance, throughput, and reliability, base station readable (e.g., RAN-aware) QoE reports can be configured by the UE. The base station readable QoE configuration, which defines the parameters used to measure and report base station readable QoE reports, can be configured by the base station (e.g., an aggregated base station, or by elements of a decomposed base station, such as a CU or DU). Thus, the UE can receive configuration messages that include multiple configurations, such as base station readable QoE configuration and QoE server configuration. The UE can measure QoE metrics and configure two reports, one intended for the base station and one intended for the QoE server. These two reports can indicate the same or similar information or different information associated with the QoE measurement and can be configured into a single message that the UE can send to the base station. In some cases, the UE can send the two reports separately.

[0067] In some implementations, such as when a UE connects to a decomposed base station, the UE may send a QoE server report, a base station readable QoE report, or both to the CU of the base station. The CU may relay at least a base station readable QoE report or a similar report to the DU of the base station. In some implementations, the UE may send at least a base station readable QoE report to the DU of the base station, and the DU may relay a base station readable QoE report or a similar report to the CU of the base station. In some cases, the base station readable QoE report that the UE may send to the DU, or the report that the DU may send to the CU, or both, may be real-time reports. For example, a base station readable report may be sent to the DU via MAC-CE. In this way, the decomposed unit in the decomposed base station can determine and perform adjustments associated with the functionality of the unit to support improved QoE at the UE without waiting for instructions from a QoE server or another unit.

[0068] Specific aspects of the subject matter described herein can be implemented to achieve one or more advantages. The described techniques can support improvements in QoE measurement and reporting by increasing flexibility in the network, improving reliability, reducing latency, and other benefits. Thus, the supported techniques can include improved network operation and, in some examples, improved network efficiency, among other benefits.

[0069] The aspects of this disclosure are initially described in the context of wireless communication systems. Subsequently, the aspects are described with regard to process flow. The aspects of this disclosure are further illustrated and described by means of and reference to apparatus diagrams, system diagrams, and flowcharts relating to QoE measurement and reporting.

[0070] Figure 1The figure illustrates an example of a wireless communication system 100 supporting QoE measurement and reporting according to aspects of this disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0071] Base stations 105 can be distributed throughout a geographic area to form a wireless communication system 100 and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. The coverage area 110 can be an example of a geographic area on which base station 105 and UE 115 can support signal communication according to one or more radio access technologies.

[0072] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Some example UE 115s are... Figure 1 It is shown in the middle. For example... Figure 1 As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network equipment (e.g., core network nodes, relay equipment, integrated access and backhaul (IAB) nodes, or other network equipment).

[0073] Base station 105 may communicate with core network 130 or with each other, or both. For example, base station 105 may interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) (or both) via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.

[0074] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base transceiver station, radio base station, access point, radio transceiver, Node (node) B, eNodeB (eNB), next-generation NodeB or gigabit-NodeB (any of which may be referred to as gNB), home NodeB, home eNodeB or other suitable terms.

[0075] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, instruments, etc.

[0076] like Figure 1 As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s that can sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations.

[0077] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 and one or more carriers. The term "carrier" can refer to a collection of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion (e.g., a bandwidth portion (BWP)) of a radio frequency spectrum band operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-APro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating the operation of the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0078] The signal waveform transmitted via a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are negatively correlated. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate that can be used for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity used for communication with UE 115.

[0079] The time interval used for base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, while N... f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time interval of the communication resource can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0080] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f Sampling period. The duration of the symbol period can depend on the subcarrier spacing or the operating frequency band.

[0081] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0082] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region (e.g., a control resource set (CORESET)) of the physical control channel can be defined by multiple symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESET) can be configured for use by a set of UEs 115. For example, one or more UEs 115 can monitor or search control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner in one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format having a given payload size. The search space set may include a common search space set configured to issue control information to multiple UEs 115 and a UE-specific search space set configured to issue control information to a specific UE 115.

[0083] In some examples, base station 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0084] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical keypad calling (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0085] In some examples, UE 115 may also be able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without the involvement of base station 105.

[0086] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) routing packets or interconnecting to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Network operator IP service 150 can include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0087] Some network devices (such as base station 105) may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0088] Wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is generally referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is from approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficiently to enable macrocells to serve UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0089] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on carrier aggregation configurations (e.g., LAA) that combine component carriers operating in licensed bands. Among other examples, operation in unlicensed spectrum can include downlink transmission, uplink transmission, P2P transmission, or D2D transmission.

[0090] Base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna accessory (such as an antenna tower). In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0091] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals communicating via antenna elements of an antenna array such that some signals propagating with respect to a particular orientation of the antenna array experience constructive interference while others experience destructive interference. Adjustments to the signals communicating via the antenna elements can include the transmitting or receiving device applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements can be defined by a beamforming weight set associated with a particular orientation (e.g., the antenna array relative to the transmitting or receiving device, or relative to some other orientation).

[0092] To support improved network performance, throughput, and reliability, UE 115 can be configured to measure QoE metrics and send QoE reports formatted to be readable by base station 105, enabling base station 105 to receive the QoE reports and independently perform adjustments associated with the services being utilized by UE 115. In some cases, the described techniques can provide real-time QoE reporting between the UE, the base station, and (in some cases) a QoE server. Furthermore, the described techniques can provide QoE measurements readable by different types of cells at a decomposed base station (e.g., a base station with CU-DU splitting). For example, UE 115 can receive a configuration message including a first configuration for reporting QoE measurements to base station 105 and a second configuration for reporting QoE measurements to a QoE server. UE 115 can measure one or more QoE metrics according to the configuration message and generate a first report for base station 105 (or cells of base station 105) based on the QoE measurements and the first configuration. After generating the report, UE 115 can send the first report to base station 105 according to the first configuration.

[0093] Figure 2 The figure illustrates an example of a wireless communication system 200 supporting QoE measurement and reporting according to aspects of this disclosure. The wireless communication system 200 may include a base station 105-a and a UE 115-a, which may be as described in reference... Figure 1 Examples of base station 105 and UE 115 are described. Base station 105-a may serve geographic coverage area 110-a. In some cases, UE 115-a may be configured to perform QoE measurement and reporting procedures. Additionally or alternatively, other wireless devices (such as base station 105-a) may implement the same or similar QoE measurement and reporting procedures.

[0094] In some cases, UE 115-a can communicate with base station 105-a via a communication link, where base station 105-a can support UE 115-a's use of applications (e.g., video applications, streaming applications, chat applications, voice applications). For example, UE 115-a can send uplink signals to base station 105-a via communication link 215-b, and base station 105-a can send downlink signals to UE 115-a via communication link 215-a, such as application-related uplink or downlink signals, or both. In some cases, base station 105-a can be a decomposed base station 105, such that base station 105-a is split into separate units. Base station 105-a may include CU 210 and one or more DU 205. In some cases, CU 210 can communicate with one or more DU 205 via communication link 215 (such as communication link 215-c). In the case of the split base station 105, UE 115-a can communicate directly with CU 210 of base station 105-a or DU 205 of base station 105-a or both via communication links 215-a and 215-b.

[0095] In some implementations, UE 115-a can utilize applications served by base station 105-a. When utilizing an application, UE 115-a can be configured to measure QoE metrics (such as throughput, error rate, etc.) and report the application-related QoE measurements to base station 105-a serving the application. Base station 105-a can relay QoE measurements to a QoE server, and the QoE server can adjust one or more parameters associated with the application based on the QoE measurements to improve application performance. In some cases, the QoE server can relay one or more adjustments that base station 105-a wants to make to service parameters associated with the served application in order to improve QoE.

[0096] For example, UE 115-a can be configured to measure QoE metrics via a QoE measurement configuration message received by UE 115-a from base station 105-a through communication link 215-a. In some cases, base station 105-a may have already received the QoE measurement configuration message from a QoE server. For example, when UE 115 is in RRC connection mode with base station 105-a, after receiving the QoE configuration from the QoE server, base station 105-a can relay the QoE configuration to UE 115-a via an RRC message (such as an RRC configuration message). Base station 105-a can include the QoE configuration in application layer-related fields (e.g., measConfigAppLayer), where the measConfigAppLayer field of the RRC reconfiguration message can include the QoE configuration and the service type associated with the QoE configuration. UE 115-a can measure QoE metrics and report these measurements to base station 105-a in application-layer associated messages (e.g., measReportAppLayer). The measReportAppLayer message can include the QoE report and an indication of the service type associated with the QoE report. In a conventional communication system, in response to receiving a measReportAppLayer message, base station 105-a can relay the QoE report within the measReportAppLayer message to the QoE server and wait to perform adjustments to application-related service parameters until it receives instructions from the QoE server. Thus, the reliability, performance, and efficiency associated with QoE optimization may be compromised.

[0097] To improve the quality and performance of applications used by UE 115, the QoE process can be modified to allow UE 115 to configure base station readable measurement reports associated with QoE. The parameters of the base station readable measurement reports can be defined by a base station readable QoE configuration, which can be sent to UE 115-a by base station 105-a (or a unit of the base station, such as CU 210 or DU 205) before UE 115-a configures the base station readable measurement reports. For example, UE 115-a can receive a configuration message from base station 105-a via communication link 215-a. This configuration message includes multiple configurations, such as a base station readable QoE configuration and a QoE server configuration. The QoE server configuration can be used by UE 115-a to generate QoE reports for the QoE server, which may be unreadable by base station 105-a. UE 115-a can measure QoE metrics associated with the service being utilized by UE 115-a, and depending on the received configuration, UE 115-a can be configured to send two reports, one intended for base station 105-a and one intended for the QoE server. These two reports can indicate the same or similar information or different information associated with the QoE measurement, and can be configured into a single message that UE 115-a can send to base station 105-a (or to a unit of the base station, such as CU 210 or DU 205) via communication link 215-b. In some cases, UE 115-a can send the two reports separately to base station 105-a.

[0098] In certain situations, such as when UE 115-a connects to a disaggregated base station (such as base station 105-a), UE 115-a may send a QoE server report, a base station readable QoE report, or both to CU 210 of base station 105-a. CU 210 may relay at least the base station readable QoE report to DU 205 of base station 105-a via communication link 215-c. In some situations, UE 115-a may send at least the base station readable QoE report to DU 205, and DU 205 may relay the base station readable QoE report to CU 210. In some implementations, the base station readable QoE report that UE-a may send to DU 205, or the report that DU 205 may send to the CU, or both, may be a real-time report. For example, the base station readable report may be sent to DU 205 via MAC-CE. Thus, the decomposed unit in the decomposed base station 105 can determine and execute adjustments associated with the unit's functionality to support improved QoE at UE 115-a without waiting for instructions from the QoE server or another unit.

[0099] Figure 3The diagram illustrates an example of a process flow 300 supporting QoE measurement and reporting according to aspects of this disclosure. Process flow 300 may illustrate an example QoE measurement and reporting process. For example, the base station may be split into CU 310 and at least one DU 305, wherein CU 310 or DU 305, or both, may participate in the QoE measurement and reporting process together with UE 115-b. CU 310 and DU 305 may be parts of the base station, wherein the base station and UE 115-b may be references. Figure 1 and 2 Examples of corresponding wireless devices are described. Alternative examples of the following can be implemented, where some steps are performed in a different order than described, or not at all. In some cases, the steps may include additional functionality not mentioned below, or further steps may be added.

[0100] For reference Figure 2 As described, UE 115 (e.g., UE 115-b) can receive a base station readable QoE configuration that indicates one or more parameters to instruct UE 115-b on how to measure and report QoE measurements. For example, at 315, CU 310 (or base station, or DU 305) can send an RRC reconfiguration message to UE 115-b. The RRC reconfiguration message may include application layer measurement configuration fields (e.g., measConfigAppLayer). The application layer measurement configuration may include a QoE configuration for measuring and reporting QoE measurements to a QoE server, a base station readable QoE configuration for measuring and reporting QoE measurements to a base station (or one or more elements of a base station), and a service type associated with the QoE configuration. In some cases, UE 115-b may receive the RRC reconfiguration message when it is in a connected mode with the base station of CU 310.

[0101] A base station-readable QoE configuration can instruct the UE 115-b to measure and report one or more metrics associated with the service type indicated in the application layer measurement configuration field. In some cases, one or more metrics may include one or more satisfactions, where the UE 115-b can determine its experience of satisfaction associated with certain communication parameters according to a pre-configured scale. For example, one or more satisfactions may include overall QoE satisfaction. Overall QoE satisfaction can be based on any number of communication parameters or any number of other satisfactions associated with the service provided to the UE 115-b. For example, overall satisfaction may be the average satisfaction of a combined set of satisfactions (e.g., satisfactions associated with bit rate, latency, and errors). The scale associated with overall QoE satisfaction may include any number of integers. For example, the scale can include integers from 1 to 5, where 1 can indicate unacceptable quality (e.g., the functionality of the service is reduced or non-existent under the current QoE), 2 can indicate that the overall satisfaction with using the service is below average, but the service (e.g., the application) continues to function, 3 can indicate average overall satisfaction, 4 can indicate overall satisfaction is above average, and 5 can indicate the highest or near-highest overall QoE experienced by UE 115-b.

[0102] In another example, one or more satisfaction levels may include bit rate satisfaction, latency satisfaction, or packet error rate (PER) satisfaction, or a combination thereof. The scale for each of the one or more satisfaction levels may be the same or different. For example, each satisfaction level may be associated with a scale of the same granularity, where each satisfaction level (e.g., overall, bit rate, latency, PER) is associated with a scale of 1 to 5. In another example, each satisfaction level may be associated with a different scale, such that overall satisfaction can be assigned a scale of 1 to 5, bit rate satisfaction can be assigned a scale of 1 to 10, and latency satisfaction can be assigned a scale of 1 to 3. The scale associated with each satisfaction level and the meaning of each number can be a static or semi-static configuration, or it can be dynamically configured.

[0103] In some cases, one or more metrics may include average throughput associated with the service, retransmission probability (e.g., the likelihood that communication associated with the service will need to be retransmitted), or an indication of latency associated with the service, wherein UE 115-b may measure and report numerical values ​​(e.g., measured actual values ​​rather than integers on a scale) for each of the throughput, retransmission probability, and latency metrics. In some cases, as part of the latency indication, UE 115-a may measure the average latency experienced by the service, and in some cases, measure the jitter (e.g., standard deviation) associated with the average. Additionally or alternatively, one or more metrics may include Hypertext Transfer Protocol (HTTP) and / or Hypertext Transfer Protocol Security (HTTPS) QoE-related metrics, such as average HTTP response time, average HTTPS response time, or both, and / or in some cases, connection setup time may be included.

[0104] The QoE configuration intended for the QoE server may instruct UE 115-b to measure one or more metrics associated with the service type indicated in the application layer measurement configuration field. In some cases, one or more of the metrics indicated in the QoE server configuration may be the same as one or more of the metrics indicated in a base station-readable QoE report. For example, the QoE server configuration may instruct UE 115-b to measure and report at least one or more of the following: service-related throughput, retransmission probability, indication of service-related latency, etc.

[0105] In response to receiving an RRC reconfiguration message, UE 115-b can identify one or more metrics to be measured based on the QoE server configuration and the base station-readable QoE configuration. UE 115-b can measure one or more metrics associated with the service indicated in the RRC reconfiguration message and configure the report to be sent to the base station. In some cases, UE 115-b can configure the report to be sent to the base station's CU310. In other cases, UE 115-b can receive an instruction to configure and send a report to CU310, where the instruction can be included in the RRC reconfiguration message, in some other message, or can be pre-configured.

[0106] At 320, UE 115-b can send a report to CU 310. In some cases, the report can be associated with the application layer of UE 115-b. For example, UE 115-b can send the report as a measReportAppLayer message. The report may include a QoE server report, a base station readable report, or both. Additionally or alternatively, the report may include an indication of the service type associated with the base station readable QoE report. In some cases, CU 310 may report to the QoE server relaying the QoE server.

[0107] At 325, CU 310 can send a QoE measurement report to DU 305. In some implementations, the QoE measurement report that CU 310 can send to DU 305 may be referred to as a non-real-time QoE report. The QoE measurement report to DU 305 may include at least a portion of the base station readable QoE measurements received by CU 310. Additionally or alternatively, the QoE measurement report to DU 305 may include an indication of the service type associated with the QoE measurement report. In some cases, CU 310 may send the QoE measurement report to DU 305 via the F1 Application Protocol (F1AP) interface. Additionally or alternatively, CU 310 may utilize the UE context setting or modification procedure to forward base station readable QoE measurements to DU 305.

[0108] When both CU 310 and DU 305 receive base station readable QoE measurements, CU 310 or DU 305, or both, may perform adjustments to one or more parameters associated with the service and used for communication with UE 115-b to improve (e.g., optimize) QoE.

[0109] Figure 4 The diagram illustrates an example of a process flow 400 supporting QoE measurement and reporting according to aspects of this disclosure. Process flow 400 may illustrate an example QoE measurement and reporting process. For example, the base station may be split into CU 410 and at least one DU 405, wherein CU 410 or DU 405, or both, may participate in the QoE measurement and reporting process together with UE 115-c. CU 410 and DU 405 may be parts of the base station, wherein the base station and UE 115-c may be references. Figures 1 to 3 Examples of corresponding wireless devices are described. Alternative examples of the following can be implemented, where some steps are performed in a different order than described, or not at all. In some cases, the steps may include additional functionality not mentioned below, or further steps may be added.

[0110] For reference Figure 3As described, UE 115 (e.g., UE 115-c) can receive a base station readable QoE configuration that can indicate one or more parameters to instruct UE 115-c how to measure and report QoE measurements. For example, at 415, CU 410 (or base station, or DU 405) can send an RRC reconfiguration message to UE 115-c. The RRC reconfiguration message may include application layer measurement configuration fields (e.g., measConfigAppLayer). The application layer measurement configuration may include a QoE configuration for measuring and reporting QoE measurements to a QoE server, a base station readable QoE configuration for measuring and reporting QoE measurements to a base station (or one or more elements of a base station), and a service type associated with the QoE configuration. In some cases, when UE 115-c is in a connection mode with a base station associated with CU 410, UE 115-c can receive the RRC reconfiguration message. The measurements included in each of the QoE server configuration and the base station readable QoE configuration are... Figure 3 It is described in the description.

[0111] In response to receiving an RRC reconfiguration message, UE 115-c can identify one or more metrics to be measured based on the QoE server configuration and base station readable configuration (e.g., as referenced). Figure 3 (Description of throughput, satisfaction, connection setup time, etc.). UE 115-c can measure one or more metrics associated with the service indicated in the RRC reconfiguration message and configure reports to be sent to the base station. In some cases, UE 115-b can be configured to send reports to DU 405 of the base station. In some cases, UE 115-b can receive instructions to configure and send reports to the DU, where such instructions can be included in the RRC reconfiguration message, in some other message, or can be pre-configured.

[0112] At 420, UE 115-c can send a report to DU 405. The report may include a QoE server report, a base station readable report, or both. Additionally or alternatively, the report may include an indication of the type of service associated with the base station readable QoE report. In some cases, UE 115-c may send a base station readable report to DU 405 and a QoE server report to CU 410, where CU 410 may relay the QoE server report to the QoE server. In some cases, UE 115-c may send the report via MAC-CE. Because the report can be sent via MAC-CE, the QoE report (including a base station readable report, a QoE server report, or both) can be referred to as a real-time report, as MAC-CE can be sent within seconds.

[0113] At 425, DU 405 can send a base station readable QoE measurement report, a QoE server report, or both to CU 410. When DU 405 sends a QoE server report to CU 410, CU 410 can relay the QoE server report to the QoE server (e.g., in non-real-time or real-time reports). In some implementations, the QoE measurement report that DU 405 can send to CU 410 may be referred to as a real-time QoE report. In some cases, the QoE measurement report to CU 410 may include an indication of the service type associated with the QoE measurement report. In some cases, DU 405 can send the QoE measurement report to CU 410 via the F1AP interface. Additionally or alternatively, DU 405 can send the QoE measurement report to the CU control plane (CU-CP), such as via the F1AP interface, and CU-UP can send the QoE measurement report to the CU user plane (CU-UP) via the E1 Application Protocol (E1AP) interface. The CU-CP can send QoE measurement reports to the CU-UP via the bearer context setting or modification process.

[0114] When both CU 410 and DU 405 receive base station readable QoE measurements, CU 410 or DU 405, or both, may perform adjustments to one or more parameters associated with the service and used for communication with UE 115-c to improve (e.g., optimize) QoE.

[0115] Figure 5 The diagram illustrates an example of a process flow 500 supporting QoE measurement and reporting according to aspects of this disclosure. Process flow 500 can illustrate an example QoE measurement and reporting process. For example, UE 115-d can measure a QoE metric and report the QoE measurement to base station 105b. Base station 105-d and UE 115-d can be references. Figures 1 to 4 Examples of corresponding wireless devices are described. In some cases, different types of wireless devices (e.g., base station 105) may perform the QoE measurement and reporting procedures instead of UE 115-d. Alternative examples of the following may be implemented, where some steps are performed in a different order than described or not at all. In some cases, the steps may include additional functionality not mentioned below, or further steps may be added.

[0116] At point 505, UE 115-d may receive a configuration message from base station 105-b (or from one or more units of base station 105-b). This configuration message includes a first configuration for reporting QoE measurements to the base station and a second configuration for reporting QoE measurements to the QoE server. The configuration message may be received from a CU of base station 105-b. In some implementations, the configuration message may include a service type associated with the QoE measurement.

[0117] At 510, UE 115-d can measure one or more QoE metrics based on the configuration message.

[0118] At point 515, UE 115-d can generate a first report for the base station based on QoE measurements and a first configuration. In some cases, the first report may include a service type provided to UE 115-d via base station 105-b, and one or more QoE measurements associated with that service type. The first report may include a real-time QoE report indicating one or more QoE measurements.

[0119] At position 520, UE 115-d can send a first report to base station 105-b (or to one or more units of base station 105-b) according to a first configuration. In some cases, UE 115-d can send the first report to the CU of base station 105-b, such as via an application layer report, according to the first configuration. In some cases, UE 115-d can send the first report to the DU of base station 105-b. UE 115-d can send the first report to the DU via uplink MAC-CE according to the first configuration.

[0120] As part of sending the first report, UE 115-d may send a set of QoE metrics formatted to be readable by base station 105-b. The set of QoE metrics may include an overall QoE satisfaction metric as one of the QoE metrics in the set, indicating satisfaction with the service provided to UE 115-d via base station 105-b. The set of QoE metrics may also include a bit rate satisfaction metric as one of the QoE metrics in the set, indicating satisfaction with the bit rate used for communication regarding the service provided to UE 115-d via base station 105-b. Finally, the set of QoE metrics may include a latency satisfaction metric as one of the QoE metrics in the set, indicating satisfaction with the latency experienced during communication regarding the service provided to UE 115-d via base station 105-b. The set of QoE metrics may include an error rate satisfaction metric as one of the QoE metrics in the set, whereby the error rate satisfaction indicates satisfaction associated with the PER (Percentage of Passive Interference) for communication regarding the service provided to UE 115-d via base station 105-b. The set of QoE metrics may include an indication of average throughput associated with communication regarding the service provided to UE 115-d via base station 105-b, an indication of retransmission probability for communication regarding the service, a standard deviation associated with communication regarding the service, or a combination thereof. The set of QoE metrics may include an indication of average HTTP response time associated with communication regarding the service provided to UE 115-d via base station 105-b, connection setup time for communication regarding the service, or a combination thereof.

[0121] In some cases, UE 115-d can generate a second report for the QoE server based on QoE measurements and a second configuration, and send the second report to the QoE server via base station 105-b, so that UE 115-d can send the second report to base station 105-b, and base station 105-b can send (e.g., relay) the second report to the QoE server.

[0122] In certain circumstances, base station 105-b may determine whether to adjust one or more parameters associated with the service provided to UE 115-d and used for communicating with UE 115-d, based on the set of QoE measurements included in the first report, wherein the set of QoE measurements is service-related.
