Technical Field

The present disclosure relates generally to communication systems, and more particularly to handling quality of experience (QoE) measurements and QoE reporting in Radio Resource Control (RRC) mode.

Background

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple-access techniques capable of supporting communication with multiple users by sharing the available system resources. Examples of such multiple-access techniques include Code Division Multiple Access (CDMA) systems, time Division Multiple Access (TDMA) systems, frequency Division Multiple Access (FDMA) systems, orthogonal Frequency Division Multiple Access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

These multiple access techniques have been employed in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the urban, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). The 5G NR is part of the continuous mobile broadband evolution promulgated by the third generation partnership project (3 GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the internet of things (IoT)), and other requirements. The 5G NR includes services associated with enhanced mobile broadband (emmbb), large-scale machine type communication (emtc), and ultra-reliable low latency communication (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements in 5G NR technology. These improvements may also be applicable to other multiple access techniques and telecommunication standards employing these techniques.

Disclosure of Invention

The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

Information associated with quality of experience (QoE) measurements performed at a User Equipment (UE) may be sent to a Radio Access Network (RAN) in a format that may not be decodable by the RAN. However, the RAN may forward QoE measurement information received from the UE to the QoE server, which may decode the QoE measurement information. Thus, even though the RAN may receive QoE measurement parameters from the UE, the RAN may not be able to decode the QoE measurement parameters for the purpose of improving the performance of the RAN.

Accordingly, the UE may determine the capabilities the UE uses to perform QoE measurements and may indicate such capabilities to the RAN before performing QoE measurements and reporting QoE measurement information to the RAN. The UE may be configured with QoE measurements, trigger/reporting information, and/or configured to report RAN-decodable parameters to the RAN. The RAN decodable parameters may be decoded at the RAN to improve performance of the RAN. For example, adjustments to reported QoE measurement parameters decoded at the RAN may improve performance of the RAN.

In one aspect of the disclosure, a method, computer-readable medium, and apparatus are provided. The apparatus may be associated with a User Equipment (UE) and configured to: transmitting, to a base station, an indication of one or more UE capabilities for at least one of multiple instances or simultaneous instances of one or more QoE measurements associated with one or more types of services at the UE; and receiving, from the base station, a QoE measurement information configuration for reporting QoE measurement information associated with the one or more types of services based on the indication of the one or more UE capabilities for the at least one of the plurality of instances or the simultaneous instance of the one or more QoE measurements.

In another aspect of the disclosure, a method, computer-readable medium, and apparatus are provided. The apparatus may be associated with a base station and configured to: receive, from a UE, an indication of one or more UE capabilities for at least one of multiple instances or simultaneous instances of one or more QoE measurements associated with one or more types of services at the UE; identifying, based on at least one of the plurality of instances or the simultaneous instance of the one or more QoE measurements at the UE or a second indication from an operations, administration, and maintenance (OAM) server, whether the base station is capable of decoding QoE measurement information for the one or more QoE measurements; and transmitting to the UE a QoE measurement information configuration for reporting of the QoE measurement information based on whether the base station is capable of decoding the QoE measurement information for the one or more QoE measurements.

In another aspect of the disclosure, a method, computer-readable medium, and apparatus are provided. The apparatus may be associated with a UE and configured to: obtaining a set of QoE measurements associated with a service type in association with a UE capability indication that the UE supports QoE measurements while in a Radio Resource Control (RRC) idle mode or an RRC inactive mode; and after entering an RRC connected mode, transmitting a QoE measurement set obtained while in the RRC idle mode or the RRC inactive mode.

In another aspect of the disclosure, a method, computer-readable medium, and apparatus are provided. The apparatus may be associated with a UE and configured to: obtaining one or more QoE measurements associated with a service type in association with a UE capability indication that the UE supports QoE measurements while in RRC idle mode or RRC inactive mode; and initiate RRC connection setup or RRC connection recovery based at least in part on obtaining the one or more QoE measurements.

To the accomplishment of the foregoing and related ends, one or more aspects comprise the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative features of the one or more aspects. These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed and the present specification is intended to include all such aspects and their equivalents.

Detailed Description

The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. It will be apparent, however, to one skilled in the art that the concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

Several aspects of the telecommunications system will now be presented with reference to various apparatus and methods. These devices and methods will be described in the detailed description below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

For example, an element or any portion of an element or any combination of elements may be implemented as a "processing system" that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics Processing Units (GPUs), central Processing Units (CPUs), application processors, digital Signal Processors (DSPs), reduced Instruction Set Computing (RISC) processors, system on a chip (SoC), baseband processors, field Programmable Gate Arrays (FPGAs), programmable Logic Devices (PLDs), state machines, gating logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in the processing system may execute the software. Software should be construed broadly to mean instructions, instruction sets, code segments, program code, programs, subroutines, software components, applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, and the like, whether referred to as software, firmware, middleware, microcode, hardware description language, or other names.

Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored or encoded on a computer-readable medium as one or more instructions or code. Computer readable media includes computer storage media. A storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise Random Access Memory (RAM), read-only memory (ROM), electrically Erasable Programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the above-described types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

Fig. 1 is a schematic diagram illustrating an example of a wireless communication system and an access network 100. A wireless communication system, also referred to as a Wireless Wide Area Network (WWAN), includes a base station 102, a UE 104, an Evolved Packet Core (EPC) 160, and another core network 190 (e.g., a 5G core (5 GC)). Base station 102 may include a macrocell (high power cellular base station) and/or a small cell (low power cellular base station). The macrocell includes a base station. Small cells include femto cells, pico cells, and micro cells.

A base station 102 configured for 4G LTE, commonly referred to as evolved Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (E-UTRAN), may interface with EPC 160 over a first backhaul link 132 (e.g., an S1 interface). A base station 102 configured for 5G NR, collectively referred to as a next generation RAN (NG-RAN), may interface with a core network 190 over a second backhaul link 184. Base station 102 may perform, among other functions, one or more of the following functions: transmission of user data, wireless channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio Access Network (RAN) sharing, multimedia Broadcast Multicast Services (MBMS), user and device tracking, RAN Information Management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through the EPC 160 or the core network 190) over a third backhaul link 134 (e.g., an X2 interface). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 may be wired or wireless.

The base station 102 may communicate wirelessly with the UE 104. Each of the base stations 102 may provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, the small cell 102 'may have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network comprising both small cells and macro cells may be referred to as a heterogeneous network. The heterogeneous network may also include home evolved node B (eNB) (HeNB) and the HeNB may provide services to a restricted group called a Closed Subscriber Group (CSG). The communication link 120 between the base station 102 and the UE 104 may include Uplink (UL) (also referred to as a reverse link) transmissions from the UE 104 to the base station 102 and/or Downlink (DL) (also referred to as a forward link) transmissions from the base station 102 to the UE 104. Communication link 120 may use multiple-input multiple-output (MIMO) antenna techniques including spatial multiplexing, beamforming, and/or transmit diversity. The communication link may be through one or more carriers. The base station 102/UE 104 may use a spectrum of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) per carrier bandwidth allocated in carrier aggregation up to yxmhz (x component carriers) in total for transmission in each direction. The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than UL). The component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell), and the secondary component carrier may be referred to as a secondary cell (SCell).

Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL/UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels such as a Physical Sidelink Broadcast Channel (PSBCH), a Physical Sidelink Discovery Channel (PSDCH), a Physical Sidelink Shared Channel (PSSCH), and a Physical Sidelink Control Channel (PSCCH). D2D communication may be through a variety of wireless D2D communication systems, such as WiMedia, bluetooth, zigBee, wi-Fi, LTE, or NR based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

The wireless communication system may also include a Wi-Fi Access Point (AP) 150 that communicates with Wi-Fi Stations (STAs) 152 via a communication link 154 in, for example, a 5GHz unlicensed spectrum or the like. When communicating in the unlicensed spectrum, STA 152/AP 150 may perform Clear Channel Assessment (CCA) prior to communication to determine whether a channel is available.

The small cell 102' may operate in licensed and/or unlicensed spectrum. When operating in unlicensed spectrum, the small cell 102' may employ NR and use the same unlicensed spectrum (e.g., 5GHz, etc.) as used by the Wi-Fi AP 150. The use of NR small cells 102' in unlicensed spectrum may improve coverage of the access network and/or increase capacity of the access network.

The electromagnetic spectrum is generally subdivided into various categories, bands, channels, etc., based on frequency/wavelength. In 5G NR, two initial operating bands have been identified as frequency range names FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). The frequency between FR1 and FR2 is commonly referred to as the mid-band frequency. Although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the "below 6GHz" band in various documents and articles. Similar naming problems sometimes occur with respect to FR2, which is commonly (interchangeably) referred to in documents and articles as the "millimeter wave" band, although it is different from the Extremely High Frequency (EHF) band (30 GHz-300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" band.

In view of the above, unless specifically stated otherwise, it should be understood that if the term "below 6GHz" or the like is used herein, it may broadly represent frequencies that may be less than 6GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless specifically stated otherwise, it should be understood that if the term "millimeter wave" or the like is used herein, it may broadly represent frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

Base station 102, whether small cell 102' or a large cell (e.g., macro base station), may include and/or be referred to as an eNB, a gndeb (gNB), or another type of base station. Some base stations (such as the gNB 180) may operate in the conventional below 6GHz spectrum, in millimeter wave frequencies, and/or near millimeter wave frequencies to communicate with the UE 104. When the gNB 180 operates in millimeter wave or near millimeter wave frequencies, the gNB 180 may be referred to as a millimeter wave base station. Millimeter-wave base station 180 may utilize beamforming 182 with UE 104 to compensate for the extremely high path loss and short distance. The base station 180 and the UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and/or antenna arrays to facilitate beamforming.

The base station 180 may transmit the beamformed signals to the UE 104 in one or more transmit directions 182'. The UE 104 may receive the beamformed signals from the base station 180 in one or more receive directions 182 ". The UE 104 may also transmit the beamformed signals in one or more transmit directions to the base station 180. The base station 180 may receive the beamformed signals from the UEs 104 in one or more directions. The base stations 180/UEs 104 may perform beam training to determine the best reception and transmission direction for each of the base stations 180/UEs 104. The transmit direction and the receive direction for the base station 180 may be the same or may be different. The transmit direction and the receive direction for the UE 104 may be the same or may be different.

EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a serving gateway 166, a Multimedia Broadcast Multicast Service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and a Packet Data Network (PDN) gateway 172.MME 162 may communicate with a Home Subscriber Server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are communicated through the serving gateway 166, which serving gateway 166 itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation as well as other functions. The PDN gateway 172 and BM-SC 170 are connected to an IP service 176.IP services 176 may include the internet, intranets, IP Multimedia Subsystem (IMS), PS streaming services, and/or other IP services. The BM-SC 170 may provide functions for MBMS user service provision and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmissions, may be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and may be used to schedule MBMS transmissions. The MBMS gateway 168 may be used to distribute MBMS traffic to base stations 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service and may be responsible for session management (start/stop) and collecting charging information related to eMBMS.

The core network 190 may include access and mobility management functions (AMFs) 192, other AMFs 193, session Management Functions (SMFs) 194, and User Plane Functions (UPFs) 195. The AMF 192 may communicate with a Unified Data Management (UDM) 196. The AMF 192 is a control node that handles signaling between the UE 104 and the core network 190. In general, AMF 192 provides QoS flows and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. The UPF 195 provides UE IP address assignment as well as other functions. The UPF 195 is connected to an IP service 197.IP services 197 may include internet, intranet, IP Multimedia Subsystem (IMS), packet Switched (PS) streaming (PSs) services, and/or other IP services.

A base station may include and/or be referred to as a gNB, a node B, eNB, an access point, a base station transceiver, a radio base station, a radio transceiver, a transceiver functional unit, a Basic Service Set (BSS), an Extended Service Set (ESS), a Transmit Receive Point (TRP), or some other suitable terminology. The base station 102 provides an access point to the EPC 160 or core network 190 for the UE 104. Examples of UEs 104 include a cellular telephone, a smart phone, a Session Initiation Protocol (SIP) phone, a laptop, a Personal Digital Assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electricity meter, an air pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similarly functioning device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meters, air pumps, ovens, vehicles, cardiac monitors, etc.). The UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handheld device, user agent, mobile client, or some other suitable terminology.

Referring again to fig. 1, in certain aspects, the UE 104 may include a UE capability indication component 198a configured to: transmitting, to a base station, an indication of one or more UE capabilities for at least one of multiple instances or simultaneous instances of one or more QoE measurements associated with one or more types of services; and receiving, from the base station, a QoE measurement information configuration for reporting QoS measurement information associated with the one or more types of services based on the indication of one or more UE capabilities for at least one of the multiple instances or simultaneous instances of the one or more QoE measurements. In certain aspects, the UE 104 may include a QoE measurement component 198b configured to: obtaining a set of QoE measurements associated with a service type in association with a UE capability indication regarding the UE supporting QoE measurements while in a Radio Resource Control (RRC) idle mode or an RRC inactive mode; and after entering the RRC connected mode, transmitting a set of QoE measurements obtained while in the RRC idle mode or the RRC inactive mode. In certain aspects, the UE 104 may include an RRC initiating component 198c configured to: obtaining one or more QoE measurements associated with the service type in association with a UE capability indication that the UE supports QoE measurements while in RRC idle mode or RRC inactive mode; and initiate RRC connection setup or RRC connection recovery based at least in part on obtaining the one or more QoE measurements.

In certain aspects, the base station 180 may include a QoE configuration component 199 configured to: receive, from the UE, an indication of one or more UE capabilities for at least one of a plurality of instances or simultaneous instances of one or more QoE measurements associated with one or more types of services at the UE; identifying whether the base station is capable of decoding QoE measurement information for one or more QoE measurements based on an indication of one or more UE capabilities for at least one of multiple instances or simultaneous instances of the one or more QoE measurements at the UE or a second indication from an operations, administration, and maintenance (OAM) server; and transmitting to the UE a QoE measurement information configuration for reporting of the QoS measurement information based on whether the base station is capable of decoding the QoE measurement information for the one or more QoE measurements. Although the following description may focus on 5G NR, the concepts described herein may be applicable to other similar fields, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

Fig. 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. Fig. 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. Fig. 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. Fig. 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be Frequency Division Duplex (FDD) in which subframes within a subcarrier set are dedicated to DL or UL for a particular subcarrier set (carrier system bandwidth), or Time Division Duplex (TDD) in which subframes within a subcarrier set are dedicated to both DL and UL for a particular subcarrier set (carrier system bandwidth). In the example provided by fig. 2A, 2C, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexibly usable between DL/UL, and subframe 3 is configured with slot format 1 (all of which are UL). Although subframes 3, 4 are shown as having slot formats 1, 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. The slot formats 0, 1 are full DL, full UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The UE is configured with a slot format (dynamically configured by DL Control Information (DCI) or semi-statically/statically configured by RRC signaling) through a received Slot Format Indicator (SFI). Note that the following description also applies to a 5G NR frame structure as TDD.

Other wireless communication technologies may have different frame structures or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more slots. The subframe may also include a minislot, which may include 7, 4, or 2 symbols. Each slot may comprise 7 or 14 symbols depending on the slot configuration. For slot configuration 0, each slot may include 14 symbols, while for slot configuration 1, each slot may include 7 symbols. The symbols on DL may be Cyclic Prefix (CP) Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. The symbols on the UL may be CP-OFDM symbols (for high throughput scenarios) or Discrete Fourier Transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also known as single carrier frequency division multiple access (SC-FDMA) symbols) (for power limited scenarios; limited to single stream transmission). The number of slots within a subframe may be based on slot configuration and digital scheme (numerology). For slot configuration 0, different digital schemes μ0 to 4 allow 1, 2, 4, 8 and 16 slots per subframe, respectively. For slot configuration 1, different digital schemes 0 to 2 allow 2, 4 and 8 slots per subframe, respectively. Accordingly, for slot configuration 0 and digital scheme μ, there are 14 symbols/slot and 2 ^μ Each slot/subframe. The subcarrier spacing and symbol length/duration are functions of the digital scheme. The subcarrier spacing may be equal to 2 ^μ *15kHz, where μ is the digital schemes 0 through 4. Thus, the digital scheme μ=0 has a subcarrier spacing of 15kHz, and the digital scheme μ=4 has a subcarrier spacing of 240 kHz. The symbol length/duration is inversely related to the subcarrier spacing. Fig. 2A-2D provide examples of slot configuration 0 (with 14 symbols per slot) and digital scheme μ=2 (with 4 slots per subframe). The slot duration is 0.25ms, the subcarrier spacing is 60kHz and the symbol duration is approximately 16.67 mus. Within the frame set, there may be one or more different bandwidth portions (BWP) of the frequency division multiplexing (see fig. 2B). Each BWP may have a specific digital scheme.

The resource grid may be used to represent a frame structure. Each slot includes Resource Blocks (RBs) (also referred to as Physical RBs (PRBs)), which include 12 consecutive subcarriers. The resource grid is divided into a plurality of Resource Elements (REs). The number of bits carried by each RE depends on the modulation scheme.

As shown in fig. 2A, some of the REs carry a reference (pilot) signal (RS) for the UE. The RSs may include demodulation RSs (DM-RSs) for channel estimation at the UE (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RSs). The RSs may also include beam measurement RSs (BRSs), beam Refinement RSs (BRRSs), and phase tracking RSs (PT-RSs).

Fig. 2B shows an example of various DL channels within a subframe of a frame. A Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including four consecutive REs in one OFDM symbol. The PDCCH within one BWP may be referred to as a control resource set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during a PDCCH monitoring occasion on CORESET, wherein the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWP may be located at a larger and/or lower frequency across the channel bandwidth. The Primary Synchronization Signal (PSS) may be within symbol 2 of a particular subframe of a frame. PSS is used by the UE 104 to determine subframe/symbol timing and physical layer identity. The Secondary Synchronization Signal (SSS) may be within symbol 4 of a particular subframe of a frame. SSS is used by the UE to determine the physical layer cell identification group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE may determine a Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS as described above. A Physical Broadcast Channel (PBCH) carrying a Master Information Block (MIB) may be logically grouped with PSS and SSS to form a Synchronization Signal (SS)/PBCH block (also referred to as an SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and a System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information, such as System Information Blocks (SIBs), not transmitted over the PBCH, and paging messages.

As shown in fig. 2C, some of the REs carry DM-RS for channel estimation at the base station (indicated as R for one particular configuration, but other DM-RS configurations are possible). The UE may transmit DM-RS for a Physical Uplink Control Channel (PUCCH) and DM-RS for a Physical Uplink Shared Channel (PUSCH). PUSCH DM-RS may be transmitted in the previous or two symbols of PUSCH. The PUCCH DM-RS may be transmitted in different configurations according to whether a short PUCCH or a long PUCCH is transmitted and according to a specific PUCCH format used. The UE may transmit a Sounding Reference Signal (SRS). The SRS may be transmitted in the last symbol of the subframe. The SRS may have a comb structure, and the UE may transmit the SRS on one of the combs. The SRS may be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

Fig. 2D shows examples of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries Uplink Control Information (UCI) such as scheduling request, channel Quality Indicator (CQI), precoding Matrix Indicator (PMI), rank Indicator (RI), and hybrid automatic repeat request (HARQ) Acknowledgement (ACK) (HARQ-ACK) information (ACK/Negative ACK (NACK)) feedback. PUSCH carries data and may additionally be used to carry Buffer Status Reports (BSR), power Headroom Reports (PHR), and/or UCI.

Fig. 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In DL, IP packets from EPC 160 may be provided to controller/processor 375. Controller/processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes an RRC layer, and layer 2 includes a Service Data Adaptation Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Medium Access Control (MAC) layer. Controller/processor 375 provides: RRC layer functions associated with: broadcast of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functions associated with: header compression/decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with: transmission of upper layer Packet Data Units (PDUs), error correction by ARQ, concatenation of RLC Service Data Units (SDUs), segmentation and reassembly, re-segmentation of RLC data PDUs, and re-ordering of RLC data PDUs; and MAC layer functions associated with: mapping between logical channels and transport channels, multiplexing of MAC SDUs onto Transport Blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction by HARQ, priority handling, and logical channel prioritization.

The Transmit (TX) processor 316 and the Receive (RX) processor 370 implement layer 1 functions associated with various signal processing functions. Layer 1, which includes a Physical (PHY) layer, may include error detection of a transmission channel, forward Error Correction (FEC) encoding/decoding of the transmission channel, interleaving, rate matching, mapping onto a physical channel, modulation/demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The encoded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to OFDM subcarriers, multiplexed with reference signals (e.g., pilots) in the time or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying the time domain OFDM symbol stream. The OFDM streams are spatially precoded to produce a plurality of spatial streams. The channel estimates from the channel estimator 374 may be used to determine the coding and modulation scheme and for spatial processing. The channel estimate may be derived from reference signals and/or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318 TX. Each transmitter 318TX may modulate an RF carrier with a respective spatial stream for transmission.

At the UE 350, each receiver 354RX receives a signal through its respective antenna 352. Each receiver 354RX recovers information modulated onto an RF carrier and provides the information to a Receive (RX) processor 356.TX processor 368 and RX processor 356 implement layer 1 functions associated with various signal processing functions. RX processor 356 can perform spatial processing on the information to recover any spatial streams destined for UE 350. If multiple spatial streams are destined for the UE 350, they may be combined into a single OFDM symbol stream by the RX processor 356. RX processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, as well as the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. These soft decisions may be based on channel estimates computed by channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to a controller/processor 359, the controller/processor 359 implementing layer 3 and layer 2 functions.

The controller/processor 359 can be associated with a memory 360 that stores program codes and data. Memory 360 may be referred to as a computer-readable medium. In the UL, controller/processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from EPC 160. The controller/processor 359 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.

Similar to the functionality described in connection with DL transmissions by the base station 310, the controller/processor 359 provides: RRC layer functions associated with: system information (e.g., MIB, SIB) acquisition, RRC connection and measurement reporting; PDCP layer functions associated with: header compression/decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with: transmission of upper layer PDUs, error correction by ARQ, concatenation of RLC SDUs, segmentation and reassembly, re-segmentation of RLC data PDUs and re-ordering of RLC data PDUs; and MAC layer functions associated with: mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction by HARQ, priority handling and logical channel prioritization.

Channel estimates derived by channel estimator 358 from reference signals or feedback transmitted by base station 310 may be used by TX processor 368 to select appropriate coding and modulation schemes, as well as to facilitate spatial processing. The spatial streams generated by TX processor 368 may be provided to different antenna 352 via separate transmitters 354 TX. Each transmitter 354TX may modulate an RF carrier with a respective spatial stream for transmission.

UL transmissions are handled at the base station 310 in a similar manner as described in connection with the receiver functionality at the UE 350. Each receiver 318RX receives a signal through its corresponding antenna 320. Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to the RX processor 370.

The controller/processor 375 may be associated with a memory 376 that stores program codes and data. Memory 376 may be referred to as a computer-readable medium. In the UL, controller/processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from UE 350. IP packets from controller/processor 375 may be provided to EPC 160. Controller/processor 375 is also responsible for error detection using ACK and/or NACK protocols to support HARQ operations.

At least one of TX processor 368, RX processor 356, and controller/processor 359 may be configured to perform aspects in conjunction with UE capability component 198a, qoE measurement component 198b, and/or RRC initiation component 198c of fig. 1.

At least one of TX processor 316, RX processor 370, and controller/processor 375 may be configured to perform aspects in conjunction with QoE configuration component 199 of fig. 1.

A wireless communication system may be configured to share available system resources and provide various telecommunication services (e.g., telephony, video, data, messaging, broadcast, etc.) based on multiple access techniques (such as CDMA systems, TDMA systems, FDMA systems, OFDMA systems, SC-FDMA systems, and TD-SCDMA systems, etc.) that support communication with multiple users. In many cases, common protocols that facilitate communication with wireless devices are employed in various telecommunications standards. For example, communication methods associated with emmbb, mctc, and URLLC may be incorporated into the 5G NR telecommunications standard, while other aspects may be incorporated into the 4G LTE standard. Since mobile broadband technology is part of continued development, further improvements in mobile broadband remain useful for continued development of such technology.

Fig. 4 is a call flow diagram 400 illustrating communication between a UE 402 and a base station 404. At 406, the UE 402 may determine UE capabilities for performing quality of experience (QoE) measurements for one or more types of services. QoE may correspond to an actual or expected level of satisfaction with telecommunications quality of service from the end user's perspective (e.g., based on objective criteria). For example, "QoE" may refer to a measurement of a service parameter determined to provide a basis for a user to enjoy a service. Accordingly, qoE may be determined with less emphasis on the range of measured parameters and with more emphasis on factors/parameters determined to provide a basis for users to enjoy services.

QoE may be based on information indicated within data sent over the network, rather than on the efficiency of data transmission. The performance of the network determined based on QoE measurements for the defined metrics may correspond to a level of satisfaction desired by the end user with respect to the defined metrics. For example, in the case where the service type is augmented reality/virtual reality (AR/VR), the QoE measurement may be associated with a measured rate of change of focus corresponding to the user's head position. QoE measurements (e.g., focus changes) assigned to such metrics may be high if the frames of the AR/VR application are updated fast enough to track adjustments in the user's head position. Other types of services may include Multimedia Telephony Services (MTSI) for IMS, multimedia Broadcast Multicast Services (MBMS), etc.

The UE capabilities determined at 406 may be based on the plurality of UE capabilities 408. For example, the first UE capability 408 (1) may be a QoE measurement capability that determines each service type. The second UE capability 408 (2) may be a simultaneous QoE measurement capability for multiple service types. The third UE capability 408 (3) may be QoE measurement capability for multiple instances of a single service type. The fourth UE capability 408 (4) may be a combined UE capability for performing both the second UE capability 408 (2) and the third UE capability 408 (3) simultaneously. The fifth UE capability 408 (5) may be a QoE measurement capability for the RRC idle state or RRC inactive state of the UE 402. At 410, the UE 402 may send an indication of the determined UE capabilities to the base station 404 based on the UE capabilities determined at 406 (e.g., associated with the plurality of UE capabilities 408).

At 412a, the UE 402 may receive, via the base station 404, from the OAM server, a RAN-decodable QoE measurement information configuration for the UE application layer, which may include trigger/report information for one or more QoE measurements of the UE 402. The trigger/report information may be received at the UE 402 as an application layer trigger/report condition. Alternatively, at 412b, the UE 402 may receive RAN-decodable parameter configurations (e.g., for storing QoE measurements) and/or indications of trigger/reporting conditions for reporting QoE measurements to the base station 404 from the RAN/base station 404. The information received by the UE 402 at 412b may be received for the RRC layer.

At 414, UE 402 may perform QoE measurements for one or more types of services. At 416, qoE measurements may be stored at the application layer (e.g., in a system architecture 4 (SA 4) container) or at the RRC layer (e.g., based on tracking Identifiers (IDs) or reference IDs). At 418, the UE 402 may send QoE measurement information to the base station 404 via an application layer or RRC layer. In configurations where the application layer is stored in the SA4 container or other application layer container in QoE measurement information, the UE 402 may send the QoE measurement information to the base station 404 or to a QoE server via the base station 404 at 418.

In some cases, qoE measurement information associated with QoE measurements performed at UE 402 may be sent to RAN/base station 404 in a SA4 container or other application layer container that may not be decodable by RAN/base station 404. The base station 404 may forward the container received from the UE 402 to a QoE server, which may extract QoE measurement information included in the container. Thus, even though the base station 404 may receive QoE measurement parameters from the UE 402 via the container, the base station 404 may not be configured to decode the QoE measurement parameters for the purpose of improving performance at the base station 404.

Thus, the UE 402 may be configured to determine the capability of the UE 402 to perform QoE measurements at 406, and may indicate such UE capability to the base station 404 at 410 prior to: qoE measurements are performed at 414, and QoE measurement information is reported to the base station 404 at 418. In aspects, at 414, qoE measurements may be performed in association with: simultaneous QoE measurements by the UE 402 (e.g., for different service types), RAN-decodable QoE measurement parameters, processing techniques for QoE measurements when the UE 402 is in an idle or inactive state, for sending QoE measurement information to the RAN including the base station 404 at 418, etc.

Example QoE measurements may be associated with adjusting focus for AR/VR applications. For example, the QoE measurement parameter of the UE 402 may indicate a rate of change of focus based on a changed head position of a user of the AR/VR application. If the network is able to update frames of the AR/VR application fast enough to stay synchronized with the user's changing perspective, the user's QoE may be at or above a defined threshold. The QoE of the user may be improved if the network is not able to update the frames of the AR/VR application fast enough to remain synchronized with the changing perspective of the user. Thus, if the QoE parameters sent to the base station 404 are decodable by the base station 404, the base station 404 may utilize the QoE parameters to increase QoE at the UE 402 when the QoE is below a defined threshold (e.g., via a change to the QoE parameters).

QoE parameters can be used for many NR applications. For example, the QoE measurements of the UE 402 may be associated with MTSI, MBMS, etc. Since the UE 402 may perform multiple types of measurements to measure QoE at 414, the UE 402 may be configured to perform QoE measurements for certain service types at 414, but may not be configured to perform QoS measurements for other service types. Thus, the capabilities of the UE 402 may be defined by service type (e.g., based on 408 (1)). That is, at 406, different UE capabilities may be determined for different QoE service types (e.g., determined based on 408 (1)). If the UE 402 supports multiple service types, at 414, the UE 402 may indicate that QoE measurements are desired to be performed for a first subset of the multiple service types, but not for a second subset of the multiple service types. For example, at 414, the UE 402 may determine to perform QoE measurements for MTSI applications, but may determine not to perform measurements for AR/VR applications. As such, the UE 402 may indicate to the base station 404 that QoE measurements may be performed for MTSI applications, but not for AR/VR applications, at 414.

The UE 402 may be configured to perform simultaneous QoE measurements for multiple service types and/or multiple instances of QoE measurements for a single service type at 414. For example, at 414, the UE 402 may perform QoE measurements on a plurality of different occasions, where for each of the different occasions, the service type may be AR/VR. Thus, the UE 402 may obtain QoE measurement information for a single service type (e.g., AR/VR) based on performing QoE measurements for the single service type over time at 414. The UE 402 may indicate to the base station 404 whether the UE 402 is configured to perform simultaneous QoE measurements for multiple service types at 414 (e.g., via the determination at 408 (2)). The UE 402 may also indicate to the base station 404 whether the UE 402 is configured to perform multiple instances of QoE measurement for a single service type at 414 (e.g., via the determination at 408 (3)). In a first aspect, the UE 402 may be independently configured to perform multiple instances of simultaneous QoE measurements for multiple service types and/or QoE measurements for a single service type at 414. In a second aspect, the UE 402 may indicate (e.g., via the determination at 408 (4)) to the base station 404 that the UE capability includes performing both simultaneous QoE measurements for multiple service types and performing multiple instances of QoE measurements for a single service type. The bit stream (e.g., associated with 2-bit UE capabilities) may be used to indicate whether the UE 402 is configured to perform simultaneous QoE measurements for multiple service types and/or multiple instances of QoE measurements for a single service type at 414.

For some service types, such as MBMS, the UE 402 may perform QoE measurements (e.g., via the determination at 408 (5)) in an RRC idle state or an RRC inactive state at 414. To indicate the capability of the UE 402 to perform QoE measurements in idle or inactive state, the UE 402 may send a separate indication to the base station 404 that the UE 402 is configured to perform QoE measurements in idle or inactive state 414. In examples, the indication may apply to all service types. That is, at 414, the UE 402 may perform QoE measurements for each of one or more service types in an idle state or an inactive state. Whether the UE 402 is configured to perform QoE measurements in an idle state or an inactive state at 414 may be based on UE capabilities for a particular service type. If the UE 402 indicates a capability to perform QoE measurements for the service type, the indication may apply to all RRC states (e.g., regardless of the current RRC state). The UE 402 may additionally provide separate indications by service type for RRC connected state and RRC idle/inactive state.

At 418, RAN decodable parameters associated with the QoE measurements performed at 414 may be reported to the base station 404 via the application layer. In examples, even though the rate of change of focus of a user of an AR/VR application may be used to improve the QoE of the user, the base station 404 may not be configured to read/decode measurement information associated with the corresponding QoE measurements. Accordingly, measurement information for QoE measurements may be sent to the base station 404 in a standardized format that may be decodable by the base station 404.

In a first aspect, at 416, RAN decodable parameters may be stored at an application layer. For QoE parameters that the RAN may not be decodable at the application layer, the SA4 container or other application layer container may be used to define a plurality of generalized QoE parameters based on the type of service associated with the QoE measurements performed at the application layer at 414. QoE parameters may be provided to the RRC layer in a separate container that the RAN/base station 404 may decode and utilize to improve the performance of the RAN/base station 404. The base station 404 may not be configured to decode QoE measurement reports of the container (e.g., larger reports generated to optimize the application layer). Thus, the RAN decodable container may be used to provide RAN decodable QoE measurement parameters to the base station 404. The RAN-decodable and non-decodable QoE measurement information may be sent from the application to the modem if the UE 402 receives a request from the base station 404, or if a trigger condition occurs. The modem may then forward the QoE measurements to the base station 404, and the base station 404 may decode the RAN-decodable parameters and forward the non-decodable parameters (e.g., non-decodable QoE measurements) to the QoE server. In a second aspect, at 416, RAN-decodable parameters may be stored at the RRC layer, wherein the base station 404 may process QoE measurement information for each service type based on predefined techniques.

The RAN decodable parameters may be requested by the base station 404 and may be configured by an OAM server. For example, the base station 404 may send a request to the OAM server to configure the RAN decodable QoE parameters. The OAM server may configure the RAN decodable parameters for QoE measurement within the SA4 container or other application layer container. That is, the OAM server may indicate a decoding process for QoE measurement at the application layer. The container including the RAN-decodable parameters may be different from the container including parameters that are not decodable by the base station 404. The RAN decodable parameters included in the container may be requested periodically by the base station 404 to improve the performance of the RAN/base station 404.

The trigger conditions for reporting RAN-decodable reports including QoE parameters and/or SA4 container/application layer container to the base station 404 at 418 may be defined via a container or RAN. The trigger conditions for reporting the RAN-decodable report to the base station 404 at 418 may be based on different trigger conditions than the trigger conditions for sending the QoE container to the base station 404. Each of the RAN-decodable measurement parameters and the non-decodable measurement parameters can be reported to the base station 404 independently at 418 or reported to the base station 404 together at 418. The reporting configuration may be based on trigger conditions reported to the base station 404 at 418.

If simultaneous QoE measurements are performed at 414, both RAN-decodable and non-decodable QoE measurement parameters may be maintained at the application layer (e.g., stored at 416). The RAN-decodable QoE measurement parameters may include QoE satisfaction level, application layer throughput, delay, jitter, etc. Separate reporting triggers for reporting QoE measurement information for each service type and/or each reference ID at 418 may be configured for the SA4 container/application layer container (e.g., each service type and/or each tracking Identifier (ID)/reference ID). The tracking ID/reference ID may be used to distinguish QoE measurements performed for multiple instances of a single service type at 414 or to distinguish simultaneous QoE measurements performed for multiple service types at 414 (e.g., based on UE capabilities determined at 408 (2) -408 (4)). The first trigger condition may be defined at the application layer and the second trigger condition may be defined by the RAN. That is, separate reporting triggers (e.g., per service type or per tracking ID/reference ID) for reporting QoE measurements per service type and/or per tracking ID/reference ID may be configured at the RAN.

In another aspect, qoE measurement configuration may be used to configure a single service type and/or a single instance of the single service type. The application layer measurement configuration may indicate a region configuration and RAN decodable parameters. If the UE 402 is configured to perform multiple QoE measurements at 414, separate QoE configurations for performing the multiple QoS measurements may be sent from the base station 404 to the UE 402. In another aspect, qoE configuration may be used to configure multiple service types and/or multiple instances of a single service type. QoE measurement configuration may be used for area configuration and RAN-decodable parameters for multiple service types that may be measured simultaneously. In some cases, the parameters of the UE 402 may indicate storage area configurations for each service type and/or RAN-decodable QoE measurements.

Fig. 5 is a call flow diagram illustrating an example 500 of QoE reporting in accordance with aspects of the present disclosure. AS shown in fig. 5, the UE may include an application layer (e.g., a High Level Operating System (HLOS)) and an access layer (AS) layer. An application layer (UE APP) may be associated with an application instance on the UE. The AS layer (UE AS) may be associated with a radio link between the UE and the base station. The base station may be associated with a cell of the wireless network, which may provide a connection to a QoE server. The QoE server may comprise, may be, or may be associated with an application instance on the UE.

As shown by reference numeral 505, the base station may receive QoE configuration information, and the QoE server may transmit the QoE configuration information. The QoE configuration information may indicate one or more parameters associated with the application to be measured. For example, the QoE configuration information may indicate that the UE is to measure throughput, latency, or error rate, among other examples. Additionally or alternatively, the QoE configuration information may indicate one or more parameters associated with measuring the one or more parameters. For example, the QoE configuration information may indicate a period of measurement of QoE parameters, a period of measurement of reporting QoE, or a service type (e.g., application type), among other examples.

AS shown by reference numeral 510, the UE may receive the RRC configuration at the UE AS and the base station may transmit the RRC configuration. The RRC configuration may include and/or may indicate a measurement configuration (e.g., measConfigAppLayer) for the application layer. The measurement configuration for the application layer may include and/or may indicate QoE configuration information and/or service types for applications (e.g., streaming and/or Multimedia Broadcast Multicast Service (MBMS), among other examples).

AS shown by reference numeral 515, the UE AS may send a command (e.g., may indicate) to the UE application layer to initiate QoE Measurement Collection (QMC). The UE AS may send the command via an interface between the UE AS and the UE application layer, such AS a wireless m-bus sensor interface module (MSM). The command may include an Attention (AT) command.

As shown by reference numeral 520, the UE application layer may send QoE measurements for each service type (e.g., each application and/or each application type, as well as other examples). For example, the UE application layer may send a first set of QoE measurements associated with the application and/or a second set of QoE measurements associated with additional applications.

AS shown by reference numeral 525, the UE AS layer may send a QoE measurement report (e.g., measReportAppLayer) and the base station may receive the QoE measurement report. The QoE measurement reports may include QoE reports and/or service types (e.g., applications or application types, among other examples). For example, the QoE measurement report may indicate a QoE measurement set and associated service type.

As shown by reference numeral 530, the base station may send a QoE report, and the QoE server may receive the QoE report. The QoE report may include one or more indications of QoE measurements associated with the QoE server. For example, the QoE report may include one or more elements of the QoE measurement report associated with the application.

As shown by reference numeral 535, the UE may receive an RRC release (e.g., RRCRelease) and the base station may transmit the RRC release. The RRC release may indicate that the UE is to enter an RRC idle mode or an RRC inactive mode. The RRC release may release a Signaling Radio Bearer (SRB) (e.g., SRB 4) associated with the uplink communication from the UE.

As shown by reference numeral 540, the UE may enter an RRC idle mode or an RRC inactive mode. When in RRC idle mode or RRC inactive mode, the UE may not be configured with resources for transmitting QoE measurement reports.

AS indicated by reference numeral 545, the UE application layer may send QoE measurements for each service type to the UE AS layer. For example, the UE application layer may continue to obtain QoE measurements during RRC idle mode or RRC inactive mode based at least in part on the QoE configuration information. While in the RRC idle mode or the RRC inactive mode, the UE may continue to receive signaling associated with the application. For example, the UE may continue to receive signaling via MBMS and/or side-uplink communications, as well as other examples.

AS indicated by reference numeral 550, the UE AS layer may discard QoE measurements based at least in part on the UE being in RRC idle mode or RRC inactive mode. In other words, when the UE is in RRC idle mode or RRC inactive mode, the UE may not transmit and/or may discard QoE measurements received from the UE application layer.

Based at least in part on the UE not sending and/or dropping QoE measurements, the QoE server may fail to receive QoE measurements. Based at least in part on the QoE server failing to receive the QoE measurements, an application server (not shown in fig. 5) associated with the QoE may fail to optimize communications with the UE. For example, the application server may fail to modify the data flow (e.g., streaming resolution and/or allowed streaming type, among other examples) optimized for the QoE measurement to the UE. In this way, the UE may receive a degraded exchange of application data with the application server, which may consume processing, network and/or communication resources to detect and correct.

As noted above, fig. 5 is provided as an example. Other examples may differ from the example described with respect to fig. 5.

In some aspects described herein, a UE may send a set of QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode. In this way, an application server associated with the QoE server may receive QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode. Based at least in part on the QoE server receiving the QoE measurements, the application server may improve communications with the UE. For example, the application server may modify the data flow (e.g., streaming resolution and/or allowed streaming type, among other examples) optimized for the measurement of QoE to the UE. In this way, the UE may enable improved exchange (e.g., transmission and/or reception) of application data with the application server, which may save processing, network, and/or communication resources that may otherwise be consumed to detect and correct degraded exchanges of application data.

In some aspects, the UE AS layer may provide an indication to the UE application layer to cease sending QoE measurements (e.g., based at least in part on the UE entering RRC idle mode or RRC inactive mode). The UE application layer may store the QoE measurements based at least in part on the indication. The UE AS layer may provide an indication (e.g., based at least in part on entering RRC connected mode) that the UE application layer is to resume sending QoE measurements. Based at least in part on the indication to resume sending QoE measurements, the UE application layer may send the QoE measurements to the UE AS layer by service type. The UE AS layer may send a QoE measurement report to the base station, which may include one or more QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode.

In some aspects, the UE application layer may obtain one or more QoE measurements while in RRC idle mode or RRC inactive mode. The UE application layer may provide QoE measurements for each service type to the UE AS layer. Based at least in part on receiving the QoE measurements, the UE AS layer may initiate RRC connection setup or RRC connection restoration to receive an allocation of resources to be used to send the QoE measurement reports.

In some aspects, the UE may be configured to perform one or more operations for reporting QoE measurements while in RRC idle mode or RRC inactive mode. For example, the UE may be configured to cease sending QoE measurements to the UE AS layer while in RRC idle mode or RRC inactive mode (e.g., via a communication protocol, configuration information from the base station or another base station, or dynamic indications from the base station or another base station, among other examples), or may be configured to initiate RRC connection setup or RRC connection restoration based at least in part on the UE AS layer receiving one or more QoE measurements.

Fig. 6 is a call flow diagram illustrating an example 600 associated with QoE reporting in radio resource control mode, in accordance with various aspects of the present disclosure. As shown in fig. 6, a UE (e.g., UE 104) may communicate with a base station (e.g., base station 102). The UE and the base station may be part of a wireless network (e.g., access network 100). In some aspects, a UE may communicate with a QoE server and/or an application server associated with a QoE service via a wireless network. In some aspects, a base station may communicate with a QoE server and/or an application server to support communication between a UE and the QoE server and/or between the UE and the application server.

As shown by reference numeral 605, a base station may receive QoE configuration information, and a QoE server may transmit the QoE configuration information. In some aspects, the QoE configuration information may indicate one or more parameters associated with the application to be measured. For example, the QoE configuration information may indicate that the UE is to measure throughput, delay, or error rate, among other examples. Additionally or alternatively, the QoE configuration information may indicate one or more parameters associated with measuring the one or more parameters. For example, the QoE configuration information may indicate a period of measurement of QoE parameters, a period of measurement of reporting QoE, or a service type (e.g., application type), among other examples.

In some aspects, the QoE configuration information may indicate that the UE is to report QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode. In some aspects, the QoE configuration information may indicate that the UE is to report QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode based at least in part on the UE satisfying one or more conditions. For example, the condition may include that the UE remains within a current tracking area or a current radio access network based notification area. Additionally or alternatively, the conditions may include that the UE remains within a set of tracking areas and/or a set of radio access network based notification areas, among other examples.

AS shown by reference numeral 610, the UE may receive RRC configurations (e.g., RRCConfig, RRCReconfiguration and/or measConfigAppLayer, among other examples) via the UE AS layer, and the base station may transmit the RRC configurations.

In some aspects, the RRC release may indicate that the UE is to continue to obtain QoE measurements while in RRC idle mode or RRC inactive mode. In some aspects, the RRC release may instruct the UE to continue to obtain QoE measurements while in RRC idle mode or RRC inactive mode based at least in part on the UE remaining in a current tracking area or a current notification area based on the radio access network. For example, the RRC release may indicate that the UE is to continue to obtain QoE measurements unless or until the UE performs a reselection procedure. In some aspects, RRC release may provide an associated indication via a boolean flag.

In some aspects, the RRC release may instruct the UE to continue to obtain QoE measurements while in RRC idle mode or RRC inactive mode based at least in part on the UE remaining in a set of tracking areas or a set of notification areas based on the radio access network. For example, the RRC release may indicate that the UE is to continue to obtain QoE measurements unless or until the UE performs a reselection procedure and determines that the reselected cell is not in the set of tracking areas or the set of notification areas based on the radio access network. In some aspects, RRC release may provide an indication of a set of tracking areas or a set of notification areas based on the radio access network.

In some aspects, the RRC release may release a Signaling Radio Bearer (SRB) (e.g., SRB 4) associated with the uplink communication from the UE. In this way, the UE may not be able to send QoE measurement reports.

AS indicated by reference numeral 630, the UE AS layer may provide an indication to cease sending QoE measurements. For example, the UE may provide the indication from a UE AS layer associated with a service type (e.g., application) based at least in part on the UE entering an RRC idle mode or an RRC inactive mode. In some aspects, the UE AS layer may provide the indication based at least in part on an RRC release indication that the UE is to send QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode. The indication is provided based at least in part on the UE AS layer, and the UE application layer may reserve QoE measurements that may otherwise be discarded at the UE AS layer based at least in part on the UE being in RRC idle mode or RRC inactive mode.

In some aspects, the UE AS layer may provide an indication to cease sending QoE measurements based at least in part on the UE satisfying one or more conditions.

In some aspects, a UE (e.g., at a UE application layer) may store QoE measurements based at least in part on the UE being in RRC idle mode or RRC inactive mode (e.g., based at least in part on an indication to cease sending QoE measurements).

As indicated by reference numeral 640, the UE may receive RRC recovery or RRC settings from the base station. As shown by reference numeral 645, the UE may enter an RRC active mode (e.g., based at least in part on the UE receiving an RRC resume or RRC setting from the base station). Based at least in part on the UE entering RRC active mode, the UE may be configured with an SRB associated with resources for transmitting QoE measurement reports.

AS shown by reference numeral 650, the UE AS layer may provide an indication to resume sending QoE measurements. In some aspects, the indication may include an AT command. In some aspects, the UE AS layer may provide the indication based at least in part on a previous transmission of the indication to cease sending QoE measurements. In some aspects, the UE AS layer may provide the indication based at least in part on the UE entering RRC active mode.

In some aspects, the UE AS layer may provide an indication to resume sending QoE measurements based at least in part on the UE failing to meet one or more conditions for sending QoE measurement reports for QoE measurements obtained while in RRC idle mode or RRC inactive mode. In some aspects, the UE AS layer may provide an indication to resume sending QoE measurements based at least in part on the UE performing a cell reselection procedure or based at least in part on the UE determining that the reselected cell is not in a set of tracking areas or a set of notification areas based on the radio access network, among other examples.

As indicated by reference numeral 655, the UE application layer may send QoE measurements for each service type. In some aspects, the UE application layer may send QoE measurements that the UE stores while in RRC idle mode or RRC inactive mode.

The QoE measurement report may include and/or indicate one or more QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode. The base station may send a QoE report to a QoE server based at least in part on the QoE measurement report.

Based at least in part on the UE transmitting a set of QoE measurements obtained when the UE is in RRC idle mode or RRC inactive mode, an application server associated with the QoE server may receive QoE measurements obtained during the UE is in RRC idle mode or RRC inactive mode. Based at least in part on the QoE server receiving the QoE measurements, the application server may improve communications with the UE. For example, the application server may modify the data flow (e.g., streaming resolution and/or allowed streaming type, among other examples) optimized for the measurement of QoE to the UE. In this way, the UE may receive an improved exchange of application data with the application server, which may save processing, network, and/or communication resources that may otherwise be consumed to detect and correct the degraded exchange of application data.

As noted above, fig. 6 is provided as an example. Other examples may differ from the example described with respect to fig. 6.

At 902, the UE may determine one or more UE capabilities for the UE to perform QoE measurements associated with one or more types of services, the QoE measurements corresponding to QoE measurement information decodable by a base station associated with the RAN. For example, referring to fig. 4, at 406, UE 402 may determine UE capabilities for QoE measurements for one or more types of services. The QoE measurements performed at 414 may correspond to QoE measurement information sent at 418 for decoding by the base station 404. One or more UE capabilities (e.g., determined at 406) may be determined to include one UE capability for each of the one or more types of services, wherein each UE capability indicates whether UE 402 may perform QoE measurements for the corresponding type of service. For example, at 408 (1), the UE 402 may determine QoE measurement capabilities for each service type. The determination at 902 may be performed by the determination component 1442 of the apparatus 1402 in fig. 14.

The one or more types of services may include multiple types of services, and the one or more UE capabilities (e.g., determined at 406) may be determined to include at least one UE capability indicating whether the UE 402 may perform simultaneous QoE measurements for the multiple types of services. For example, at 408 (2), the UE 402 may determine simultaneous QoE measurement capabilities for multiple service types. The one or more UE capabilities (e.g., determined at 406) may be determined to include at least one UE capability indicating whether the UE 402 may perform a plurality of QoE measurements for at least one of the one or more types of services. For example, at 408 (3), the UE 402 may determine QoE measurement capabilities for multiple instances of a single service type. The one or more types of services may include multiple types of services, and the one or more UE capabilities (e.g., determined at 406) may be determined to include at least one UE capability indicating whether the UE 402 may perform simultaneous QoE measurements for multiple types of services and whether the UE 402 may perform multiple QoE measurements for each of the multiple types of services. For example, at 408 (4), the UE 402 may determine a combined UE capability for performing both 408 (2) and 408 (3).

The one or more UE capabilities (e.g., determined at 406) may be determined to include at least one UE capability indicating whether the UE 402 may perform QoE measurements for one or more types of services when the UE 402 is in at least one of an idle state or an inactive state with respect to each of the one or more types of services. For example, at 408 (5), the UE 402 may determine QoE measurement capability for RRC idle/inactive state. In a first aspect, one or more UE capabilities (e.g., determined at 406) may be determined to include one UE capability for each of the one or more types of services, wherein each UE capability indicates whether UE 402 may perform QoE measurements for the corresponding type of service when UE 402 is in any RRC state with respect to the corresponding type of service. In a second aspect, one or more UE capabilities (e.g., determined at 406) may be determined to include a plurality of UE functions for each of the one or more types of services such that a first UE capability of the plurality of UE capabilities for each type of service may indicate whether the UE 402 may perform QoE measurements for the corresponding type of service when the UE 402 is in an RRC connected state with respect to the corresponding type of service, and a second UE capability of the plurality of UE capabilities for each type of service may indicate whether the UE 402 may perform QoE measurements for the corresponding type of service when the UE 402 is in at least one of an RRC idle state or an RRC inactive state with respect to the corresponding type of service.

For example, referring to fig. 4, at 412a, the UE 402 may receive a QoE measurement information configuration in an application layer. The trigger/reporting conditions for QoE measurement information may be received from an OAM server via the base station 404, and may cause the UE 402 to perform QoE measurements for one or more types of services at 414 and/or report QoE measurement information to the base station 404 at 418. The information received at 412a may be associated with a SA4 container for QoE measurement information configuration. The receiving at 906 may be performed by the receiving component 1430 of the apparatus 1402 in fig. 14.

At 908, if the base station indicates RAN-decodable information to the UE, the UE may receive information from the RAN associated with at least one of a RAN-decodable configuration for storing QoE measurements or a trigger condition for reporting QoE measurements, the reporting of QoE measurements being triggered based on receiving the information at the RRC layer. For example, referring to fig. 4, at 412b, the UE 402 may receive information associated with RAN-decodable configuration for storing QoE measurements (e.g., performed at 414) and/or trigger/reporting conditions from the base station 404 via the RRC layer, which may cause the UE 402 to report (e.g., at 418) the QoE measurement information to the base station 404. The receiving at 908 may be performed by the receiving component 1430 of the apparatus 1402 in fig. 14.

At 912, the UE may send QoE measurement information indicating QoE measurements to a base station associated with the RAN for processing at the RAN through one of an application layer at the UE or an RRC layer at the UE. For example, referring to fig. 4, at 418, the UE 402 may send/report QoE measurement information to the RAN/base station 404 via an application layer of the RRC layer. The QoE measurement information sent/reported at 418 may indicate the QoE measurements performed for one or more types of services at 414 and may be configured for processing at the RAN/base station 404. The transmission at 912 may be performed by a transmission component 1434 of the apparatus 1402 in fig. 14.

For example, referring to fig. 4, at 412b, the base station 404 may indicate RAN decoding parameters to the UE 402 via the RRC layer based on the UE capabilities indicated from the UE 402 at 410 and/or the indication received from the OAM. The identification at 1004 may be performed by the identification component 1540 of the apparatus 1502 in fig. 15.

At 1006, the base station may send a QoE measurement information configuration for reporting of QoE measurement information to the UE based on whether the base station can decode the QoE measurement information for one or more QoE measurements. For example, referring to fig. 4, at 412a, base station 404 may send a QoE measurement information configuration to UE 402 based on the UE capabilities indicated from UE 402 at 410 and/or the indication received from OAM. The transmission at 1006 may be performed by the transmission component 1534 of the apparatus 1502 in fig. 15.
