Title: End-to-end (E2E) performance measurements in 5G networks

Abstract:
An apparatus of a management service equipment includes processing circuitry. To configure the management service equipment for E2E performance measurements in a 5G network with a plurality of network functions (NFs), the processing circuitry is to decode RAN latency received from a RAN within the 5G network. The RAN latency is associated with transmission of an Internet protocol (IP) packet between a UE and a data network (DN) via the RAN. A user plane function (UPF) latency associated with communication of the IP packet between the RAN and a UPF within the 5G network is determined. A DN latency associated with communication of the IP packet between the UPF and the DN is determined. An E2E performance measurement calculation is performed to determine an E2E latency associated with communicating the IP packet between the UE and the DN based on the RAN latency, the UPF latency, and the DN latency.

Description:
PRIORITY CLAIM 
     This application claims the benefit of priority to U.S. Provisional Patent Application Ser. No. 62/715,583, filed Aug. 7, 2018, and entitled “END-TO-END PERFORMANCE MEASUREMENTS FOR 5G NETWORKS,” which provisional patent application is incorporated herein by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     Aspects pertain to wireless communications. Some aspects relate to wireless networks including 3GPP (Third Generation Partnership Project) networks, 3GPP LTE (Long Term Evolution) networks, 3GPP LTE-A (LTE Advanced) networks, and fifth-generation (5G) networks including 5G new radio (NR) (or 5G-NR) networks and 5G-LTE networks. Other aspects are directed to systems and methods for configuring transmission configuration indication (TCI) and quasi co-location (QCL) information in 5G networks. 
     BACKGROUND 
     Mobile communications have evolved significantly from early voice systems to today&#39;s highly sophisticated integrated communication platform. With the increase in different types of devices communicating with various network devices, usage of 3GPP LTE systems has increased. The penetration of mobile devices (user equipment or UEs) in modern society has continued to drive demand for a wide variety of networked devices in a number of disparate environments. Fifth generation (5G) wireless systems are forthcoming and are expected to enable even greater speed, connectivity, and usability. Next generation 5G networks (or NR networks) are expected to increase throughput, coverage, and robustness and reduce latency and operational and capital expenditures. 5G-NR networks will continue to evolve based on 3GPP LTE-Advanced with additional potential new radio access technologies (RATs) to enrich people&#39;s lives with seamless wireless connectivity solutions delivering fast, rich content and services. As current cellular network frequency is saturated, higher frequencies, such as millimeter wave (mmWave) frequency, can be beneficial due to their high bandwidth. 
     Potential LTE operation in the unlicensed spectrum includes (and is not limited to) the LTE operation in the unlicensed spectrum via dual connectivity (DC), or DC-based LAA, and the standalone LTE system in the unlicensed spectrum, according to which LTE-based technology solely operates in unlicensed spectrum without requiring an “anchor” in the licensed spectrum, called MulteFire. MulteFire combines the performance benefits of LTE technology with the simplicity of Wi-Fi-like deployments. 
     Further enhanced operation of LTE systems in the licensed as well as unlicensed spectrum is expected in future releases and 5G systems. Such enhanced operations can include techniques to configure E2E performance measurements in 5G-NR networks.

     DETAILED DESCRIPTION 
     The following description and the drawings sufficiently illustrate aspects to enable those skilled in the art to practice them. Other aspects may incorporate structural, logical, electrical, process, and other changes. Portions and features of some aspects may be included in, or substituted for, those of other aspects. Aspects set forth in the claims encompass all available equivalents of those claims. 
       FIG.  1 A  illustrates an architecture of a network in accordance with some aspects. The network  140 A is shown to include user equipment (UE)  101  and UE  102 . The UEs  101  and  102  are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks) but may also include any mobile or non-mobile computing device, such as Personal Data Assistants (PDAs), pagers, laptop computers, desktop computers, wireless handsets, drones, or any other computing device including a wired and/or wireless communications interface. The UEs  101  and  102  can be collectively referred to herein as UE  101 , and UE  101  can be used to perform one or more of the techniques disclosed herein. 
     Any of the radio links described herein (e.g., as used in the network  140 A or any other illustrated network) may operate according to any exemplary radio communication technology and/or standard. 
     LTE and LTE-Advanced are standards for wireless communications of high-speed data for UE such as mobile telephones. In LTE-Advanced and various wireless systems, carrier aggregation is a technology according to which multiple carrier signals operating on different frequencies may be used to carry communications for a single UE, thus increasing the bandwidth available to a single device. In some aspects, carrier aggregation may be used where one or more component carriers operate on unlicensed frequencies. 
     There are emerging interests in the operation of LTE systems in the unlicensed spectrum. As a result, an important enhancement for LTE in 3GPP Release 13 has been to enable its operation in the unlicensed spectrum via Licensed-Assisted Access (LAA), which expands the system bandwidth by utilizing the flexible carrier aggregation (CA) framework introduced by the LTE-Advanced system. Rel-13 LAA system focuses on the design of downlink operation on unlicensed spectrum via CA, while Rel-14 enhanced LAA (eLAA) system focuses on the design of uplink operation on unlicensed spectrum via CA. 
     Aspects described herein can be used in the context of any spectrum management scheme including, for example, dedicated licensed spectrum, unlicensed spectrum, (licensed) shared spectrum (such as Licensed Shared Access (LSA) in 2.3-2.4 GHz, 3.4-3.6 GHz, 3.6-3.8 GHz, and further frequencies and Spectrum Access System (SAS) in 3.55-3.7 GHz and further frequencies). 
     Aspects described herein can also be applied to different Single Carrier or OFDM flavors (CP-OFDM, SC-FDMA, SC-OFDM, filter bank-based multicarrier (FBMC), OFDMA, etc.) and in particular 3GPP NR (New Radio) by allocating the OFDM carrier data bit vectors to the corresponding symbol resources. 
     In some aspects, any of the UEs  101  and  102  can comprise an Internet-of-Things (IoT) UE or a Cellular IoT (CIoT) UE, which can comprise a network access layer designed for low-power IoT applications utilizing short-lived UE connections. In some aspects, any of the UEs  101  and  102  can include a narrowband (NB) IoT UE (e.g., such as an enhanced NB-IoT (eNB-IoT) UE and Further Enhanced (FeNB-IoT) UE). An IoT UE can utilize technologies such as machine-to-machine (M2M) or machine-type communications (MTC) for exchanging data with an MTC server or device via a public land mobile network (PLMN), Proximity-Based Service (ProSe) or device-to-device (D2D) communication, sensor networks, or IoT networks. The M2M or MTC exchange of data may be a machine-initiated exchange of data. An IoT network includes interconnecting IoT UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure), with short-lived connections. The IoT UEs may execute background applications (e.g., keep-alive messages, status updates, etc.) to facilitate the connections of the IoT network. 
     In some aspects, NB-IoT devices can be configured to operate in a single physical resource block (PRB) and may be instructed to retune two different PRBs within the system bandwidth. In some aspects, an eNB-IoT UE can be configured to acquire system information in one PRB, and then it can retune to a different PRB to receive or transmit data. 
     In some aspects, any of the UEs  101  and  102  can include enhanced MTC (eMTC) UEs or further enhanced MTC (FeMTC) UEs. 
     The UEs  101  and  102  may be configured to connect, e.g., communicatively couple, with a radio access network (RAN)  110 . The RAN  110  may be, for example, an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), a NextGen RAN (NG RAN), or some other type of RAN. The UEs  101  and  102  utilize connections  103  and  104 , respectively, each of which comprises a physical communications interface or layer (discussed in further detail below); in this example, the connections  103  and  104  are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as a Global System for Mobile Communications (GSM) protocol, a code-division multiple access (CDMA) network protocol, a Push-to-Talk (PTT) protocol, a PTT over Cellular (POC) protocol, a Universal Mobile Telecommunications System (UMTS) protocol, a 3GPP Long Term Evolution (LTE) protocol, a fifth generation (5G) protocol, a New Radio (NR) protocol, and the like. 
     In some aspects, the network  140 A can include a core network (CN)  120 . Various aspects of NG RAN and NG Core are discussed herein in reference to, e.g.,  FIG.  1 B ,  FIG.  1 C ,  FIG.  1 D ,  FIG.  1 E , and  FIG.  1 F . 
     In an aspect, the UEs  101  and  102  may further directly exchange communication data via a ProSe interface  105 . The ProSe interface  105  may alternatively be referred to as a sidelink interface comprising one or more logical channels, including but not limited to a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), a Physical Sidelink Discovery Channel (PSDCH), and a Physical Sidelink Broadcast Channel (PSBCH). 
     The UE  102  is shown to be configured to access an access point (AP)  106  via connection  107 . The connection  107  can comprise a local wireless connection, such as, for example, a connection consistent with any IEEE 802.11 protocol, according to which the AP  106  can comprise a wireless fidelity (WiFi®) router. In this example, the AP  106  is shown to be connected to the Internet without connecting to the core network of the wireless system (described in further detail below). 
     The RAN  110  can include one or more access nodes that enable the connections  103  and  104 . These access nodes (ANs) can be referred to as base stations (BSs), NodeBs, evolved NodeBs (eNBs), Next Generation NodeBs (gNBs), RAN nodes, and the like, and can comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell). In some aspects, the communication nodes  111  and  112  can be transmission/reception points (TRPs). In instances when the communication nodes  111  and  112  are NodeBs (e.g., eNBs or gNBs), one or more TRPs can function within the communication cell of the NodeBs. The RAN  110  may include one or more RAN nodes for providing macrocells, e.g., macro RAN node  111 , and one or more RAN nodes for providing femtocells or picocells (e.g., cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells), e.g., low power (LP) RAN node  112 . 
     Any of the RAN nodes  111  and  112  can terminate the air interface protocol and can be the first point of contact for the UEs  101  and  102 . In some aspects, any of the RAN nodes  111  and  112  can fulfill various logical functions for the RAN  110  including, but not limited to, radio network controller (RNC) functions such as radio bearer management, uplink and downlink dynamic radio resource management and data packet scheduling, and mobility management. In an example, any of the nodes  111  and/or  112  can be a new generation node-B (gNB), an evolved node-B (eNB), or another type of RAN node. 
     In accordance with some aspects, the UEs  101  and  102  can be configured to communicate using Orthogonal Frequency-Division Multiplexing (OFDM) communication signals with each other or with any of the RAN nodes  111  and  112  over a multicarrier communication channel in accordance various communication techniques, such as, but not limited to, an Orthogonal Frequency-Division Multiple Access (OFDMA) communication technique (e.g., for downlink communications) or a Single Carrier Frequency Division Multiple Access (SC-FDMA) communication technique (e.g., for uplink and ProSe for sidelink communications), although such aspects are not required. The OFDM signals can comprise a plurality of orthogonal subcarriers. 
     In some aspects, a downlink resource grid can be used for downlink transmissions from any of the RAN nodes  111  and  112  to the UEs  101  and  102 , while uplink transmissions can utilize similar techniques. The grid can be a time-frequency grid, called a resource grid or time-frequency resource grid, which is the physical resource in the downlink in each slot. Such a time-frequency plane representation may be used for OFDM systems, which makes it applicable for radio resource allocation. Each column and each row of the resource grid may correspond to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain may correspond to one slot in a radio frame. The smallest time-frequency unit in a resource grid may be denoted as a resource element. Each resource grid may comprise a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block may comprise a collection of resource elements; in the frequency domain, this may, in some aspects, represent the smallest quantity of resources that currently can be allocated. There may be several different physical downlink channels that are conveyed using such resource blocks. 
     The physical downlink shared channel (PDSCH) may carry user data and higher-layer signaling to the UEs  101  and  102 . The physical downlink control channel (PDCCH) may carry information about the transport format and resource allocations related to the PDSCH channel, among other things. It may also inform the UEs  101  and  102  about the transport format, resource allocation, and H-ARQ (Hybrid Automatic Repeat Request) information related to the uplink shared channel. Typically, downlink scheduling (assigning control and shared channel resource blocks to the UE  102  within a cell) may be performed at any of the RAN nodes  111  and  112  based on channel quality information fed back from any of the UEs  101  and  102 . The downlink resource assignment information may be sent on the PDCCH used for (e.g., assigned to) each of the UEs  101  and  102 . 
     The RAN  110  is shown to be communicatively coupled to a core network (CN)  120  via an S1 interface  113 . In aspects, the CN  120  may be an evolved packet core (EPC) network, a NextGen Packet Core (NPC) network, or some other type of CN (e.g., as illustrated in reference to  FIGS.  1 B- 1 I ). In this aspect, the S1 interface  113  is split into two parts: the S1-U interface  114 , which carries traffic data between the RAN nodes  111  and  112  and the serving gateway (S-GW)  122 , and the S1-mobility management entity (MME) interface  115 , which is a signaling interface between the RAN nodes  111  and  112  and MMEs  121 . 
     In this aspect, the CN  120  comprises the MMEs  121 , the S-GW  122 , the Packet Data Network (PDN) Gateway (P-GW)  123 , and a home subscriber server (HSS)  124 . The MMEs  121  may be similar in function to the control plane of legacy Serving General Packet Radio Service (GPRS) Support Nodes (SGSN). The MMEs  121  may manage mobility aspects in access such as gateway selection and tracking area list management. The HSS  124  may comprise a database for network users, including subscription-related information to support the network entities&#39; handling of communication sessions. The CN  120  may comprise one or several HSSs  124 , depending on the number of mobile subscribers, on the capacity of the equipment, on the organization of the network, etc. For example, the HSS  124  can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. 
     The S-GW  122  may terminate the S1 interface  113  towards the RAN  110 , and routes data packets between the RAN  110  and the CN  120 . In addition, the S-GW  122  may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities of the S-GW  122  may include a lawful intercept, charging, and some policy enforcement. 
     The P-GW  123  may terminate an SGi interface toward a PDN. The P-GW  123  may route data packets between the EPC network  120  and external networks such as a network including the application server  184  (alternatively referred to as application function (AF)) via an Internet Protocol (IP) interface  125 . The P-GW  123  can also communicate data to other external networks  131 A, which can include the Internet, IP multimedia subsystem (IPS) network, and other networks. Generally, the application server  184  may be an element offering applications that use IP bearer resources with the core network (e.g., UMTS Packet Services (PS) domain, LTE PS data services, etc.). In this aspect, the P-GW  123  is shown to be communicatively coupled to an application server  184  via an IP interface  125 . The application server  184  can also be configured to support one or more communication services (e.g., Voice-over-Internet Protocol (VoIP) sessions, PTT sessions, group communication sessions, social networking services, etc.) for the UEs  101  and  102  via the CN  120 . 
     The P-GW  123  may further be a node for policy enforcement and charging data collection. Policy and Charging Rules Function (PCRF)  126  is the policy and charging control element of the CN  120 . In a non-roaming scenario, in some aspects, there may be a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with a UE&#39;s Internet Protocol Connectivity Access Network (IP-CAN) session. In a roaming scenario with a local breakout of traffic, there may be two PCRFs associated with a UE&#39;s IP-CAN session: a Home PCRF (H-PCRF) within an HPLMN and a Visited PCRF (V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF  126  may be communicatively coupled to the application server  184  via the P-GW  123 . The application server  184  may signal the PCRF  126  to indicate a new service flow and select the appropriate Quality of Service (QoS) and charging parameters. The PCRF  126  may provision this rule into a Policy and Charging Enforcement Function (PCEF) (not shown) with the appropriate traffic flow template (TFT) and QoS class of identifier (QCI), which commences the QoS and charging as specified by the application server  184 . 
     In an example, any of the nodes  111  or  112  can be configured to communicate to the UEs  101 ,  102  (e.g., dynamically) an antenna panel selection and a receive (Rx) beam selection that can be used by the UE for data reception on a physical downlink shared channel (PDSCH) as well as for channel state information reference signal (CSI-RS) measurements and channel state information (CSI) calculation. 
     In an example, any of the nodes  111  or  112  can be configured to communicate to the UEs  101 ,  102  (e.g., dynamically) an antenna panel selection and a transmit (Tx) beam selection that can be used by the UE for data transmission on a physical uplink shared channel (PUSCH) as well as for sounding reference signal (SRS) transmission. 
     In some aspects, the communication network  140 A can be an IoT network. One of the current enablers of IoT is the narrowband-IoT (NB-IoT). NB-IoT has objectives such as coverage extension, UE complexity reduction, long battery lifetime, and backward compatibility with the LTE network. In addition, NB-IoT aims to offer deployment flexibility allowing an operator to introduce NB-IoT using a small portion of its existing available spectrum, and operate in one of the following three modalities: (a) standalone deployment (the network operates in re-farmed GSM spectrum); (b) in-band deployment (the network operates within the LTE channel); and (c) guard-band deployment (the network operates in the guard band of legacy LTE channels). In some aspects, such as with further enhanced NB-IoT (FeNB-IoT), support for NB-IoT in small cells can be provided (e.g., in microcell, picocell or femtocell deployments). One of the challenges NB-IoT systems face for small cell support is the UL/DL link imbalance, where for small cells the base stations have lower power available compared to macro-cells, and, consequently, the DL coverage can be affected and/or reduced. In addition, some NB-IoT UEs can be configured to transmit at maximum power if repetitions are used for UL transmission. This may result in large inter-cell interference in dense small cell deployments.

       FIG.  1 D  illustrates an example Evolved Universal Terrestrial Radio Access (E-UTRA) New Radio Dual Connectivity (EN-DC) architecture, in accordance with some aspects. Referring to  FIG.  1 D , the EN-DC architecture  140 D includes radio access network (or E-TRA network, or E-TRAN)  110  and EPC  120 . The EPC  120  can include MMEs  121  and S-GWs  122 . The E-UTRAN  110  can include nodes  111  (e.g., eNBs) as well as Evolved Universal Terrestrial Radio Access New Radio (EN) next generation evolved Node-Bs (en-gNBs)  128 .

The eNBs  111  can be configured as master nodes (or MeNBs) and the eNBs  128  can be configured as secondary nodes (or SgNBs) in the EN-DC communication architecture  140 D. As illustrated in  FIG.  1 D , the eNBs  111  are connected to the EPC  120  via the S1 interface and to the EN-gNBs  128  via the X2 interface. The EN-gNBs (or SgNBs)  128  may be connected to the EPC  120  via the S1-U interface, and to other EN-gNBs via the X2-U interface. The SgNB  128  can communicate with the UE  102  via a UU interface (e.g., using signaling radio bearer type 3, or SRB3 communications as illustrated in  FIG.  1 D ), and with the MeNB  111  via an X2 interface (e.g., X2-C interface). The MeNB  111  can communicate with the UE  102  via a UU interface. 
     Even though  FIG.  1 D  is described in connection with EN-DC communication environment, other types of dual connectivity communication architectures (e.g., when the UE  102  is connected to a master node and a secondary node) can also use the techniques disclosed herein. 
     In some aspects, the MeNB  111  can be connected to the MME  121  via S1-MME interface and to the SgNB  128  via an X2-C interface. In some aspects, the MeNB  111  can be connected to the SGW  122  via S1-U interface and to the SgNB  128  via an X2-U interface. In some aspects associated with dual connectivity (DC) and/or MultiRate-DC (MR-DC), the Master eNB (MeNB) can offload user plane traffic to the Secondary gNB (SgNB) via split bearer or SCG (Secondary Cell Group) split bearer. 
       FIG.  1 E  illustrates a non-roaming 5G system architecture in accordance with some aspects. Referring to  FIG.  1 E , there is illustrated a 5G system architecture  140 E in a reference point representation. More specifically, UE  102  can be in communication with RAN  110  as well as one or more other 5G core (5GC) network entities. The 5G system architecture  140 E includes a plurality of network functions (NFs), such as access and mobility management function (AMF)  132 , session management function (SMF)  136 , policy control function (PCF)  148 , application function (AF)  150 , user plane function (UPF)  134 , network slice selection function (NSSF)  142 , authentication server function (AUSF)  144 , and unified data management (UDM)/home subscriber server (HSS)  146 . The UPF  134  can provide a connection to a data network (DN)  152 , which can include, for example, operator services, Internet access, or third-party services. The AMF  132  can be used to manage access control and mobility and can also include network slice selection functionality. The SMF  136  can be configured to set up and manage various sessions according to a network policy. The UPF  134  can be deployed in one or more configurations according to a desired service type. The PCF  148  can be configured to provide a policy framework using network slicing, mobility management, and roaming (similar to PCRF in a 4G communication system). The UDM can be configured to store subscriber profiles and data (similar to an HSS in a 4G communication system). 
     In some aspects, the 5G system architecture  140 E includes an IP multimedia subsystem (IMS)  168 E as well as a plurality of IP multimedia core network subsystem entities, such as call session control functions (CSCFs). More specifically, the IMS  168 E includes a CSCF, which can act as a proxy CSCF (P-CSCF)  162 E, a serving CSCF (S-CSCF)  164 E, an emergency CSCF (E-CSCF) (not illustrated in  FIG.  1 E ), or interrogating CSCF (I-CSCF)  166 E. The P-CSCF  162 E can be configured to be the first contact point for the UE  102  within the IM subsystem (IMS)  168 E. The S-CSCF  164 E can be configured to handle the session states in the network, and the E-CSCF can be configured to handle certain aspects of emergency sessions such as routing an emergency request to the correct emergency center or PSAP. The I-CSCF  166 E can be configured to function as the contact point within an operator&#39;s network for all IMS connections destined to a subscriber of that network operator, or a roaming subscriber currently located within that network operator&#39;s service area. In some aspects, the I-CSCF  166 E can be connected to another IP multimedia network  170 E, e.g. an IMS operated by a different network operator. 
     In some aspects, the UDM/HSS  146  can be coupled to an application server  160 E, which can include a telephony application server (TAS) or another application server (AS). The AS  160 E can be coupled to the IMS  168 E via the S-CSCF  164 E or the I-CSCF  166 E. In some aspects, the 5G system architecture  140 E can use unified access barring mechanism using one or more of the techniques described herein, which access barring mechanism can be applied for all RRC states of the UE  102 , such as RRC_IDLE, RRC_CONNECTED, and RRC_INACTIVE states. 
     In some aspects, the 5G system architecture  140 E can be configured to use 5G access control mechanism techniques described herein, based on access categories that can be categorized by a minimum default set of access categories, which are common across all networks. This functionality can allow the public land mobile network PLMN, such as a visited PLMN (VPLMN) to protect the network against different types of registration attempts, enable acceptable service for the roaming subscriber and enable the VPLMN to control access attempts aiming at receiving certain basic services. It also provides more options and flexibility to individual operators by providing a set of access categories, which can be configured and used in operator-specific ways. 
     A reference point representation shows that interaction can exist between corresponding NF services. For example,  FIG.  1 E  illustrates the following reference points: N1 (between the UE  102  and the AMF  132 ), N2 (between the RAN  110  and the AMF  132 ), N3 (between the RAN  110  and the UPF  134 ), N4 (between the SMF  136  and the UPF  134 ), N5 (between the PCF  148  and the AF  150 , not shown), N6 (between the UPF  134  and the DN  152 ), N7 (between the SMF  136  and the PCF  148 , not shown), N8 (between the UDM  146  and the AMF  132 , not shown), N9 (between two UPFs  134 , not shown), N10 (between the UDM  146  and the SMF  136 , not shown), N1 l  (between the AMF  132  and the SMF  136 , not shown), N12 (between the AUSF  144  and the AMF  132 , not shown), N13 (between the AUSF  144  and the UDM  146 , not shown), N14 (between two AMFs  132 , not shown), N15 (between the PCF  148  and the AMF  132  in case of a non-roaming scenario, or between the PCF  148  and a visited network and AMF  132  in case of a roaming scenario, not shown), N16 (between two SMFs, not shown), and N22 (between AMF  132  and NSSF  142 , not shown).

Referring to  FIG.  2   , the 5G-NR architecture  200  can include a 5G core  212  and NG-RAN  214 . The NG-RAN  214  can include one or more gNBs such as gNB  128 A and  128 B (which can be the same as gNB  128 ). The 5GC  212  and the NG-RAN  214 , in some aspects, may be similar or the same as the 5GC  120  and the NG-RAN  110  of  FIG.  1 B , respectively. In some aspects, network elements of the NG-RAN  214  may be split into central and distributed units, and different central and distributed units, or components of the central and distributed units, may be configured for performing different protocol functions. For example, different protocol functions of the protocol layers depicted in  FIG.  4    or  FIG.  5   .

The gNB-CU  202  is a logical node configured to host the radio resource control layer (RRC), service data adaptation protocol (SDAP) layer and packet data convergence protocol layer (PDCP) protocols of the gNB or RRC, and PDCP protocols of the E-UTRA-NR gNB (en-gNB) that controls the operation of one or more gNB-DUs. The gNB-DU (e.g.,  204  or  206 ) is a logical node configured to host the radio link control layer (RLC), medium access control layer (MAC) and physical layer (PHY) layers of the gNB  128 A,  128 B or en-gNB, and its operation is at least partly controlled by gNB-CU  202 . In some aspects, one gNB-DU (e.g.,  204 ) can support one or multiple cells. 
     The gNB-CU  202  comprises a gNB-CU-Control Plane (gNB-CU-CP) entity  208  and a gNB-CU-User Plane entity  210 . The gNB-CU-CP  208  is a logical node configured to host the RRC and the control plane part of the PDCP protocol of the gNB-CU  202  for an en-gNB or a gNB.

     In some aspects, 5G services (e.g., enhanced mobile broadband (eMBB), ultra reliable low latency communications (URLLC), or massive machine-type communications (mMTC)) may have requirements on end-to-end (E2E) performance of the 5G network. In this regard, E2E performance measurements may be defined for 5G networks using the techniques disclosed herein. The E2E performance measurements may be used as key data to for performance assurance of 5G networks including network slicing. 
     In some aspects, existing 3GPP technical specifications (TSs) (e.g., TS 28.552) may be supplemented to define E2E latency measurements and may also include clarifications on how the measurements are counted and which network functions (NFs) are involved to support the E2E measurements. In some aspects, the average E2E latency may be calculated by accumulation of average delays and latencies existing on each interface and at each network function (e.g., as data is traversing a communication path from a UE towards a DN). In some aspects, the E2E virtualized resource (VR) usage measurement may be defined. Techniques disclosed herein may be used to determine which NF measurements can be used to support E2E measurements. 
     Examples of 5G NFs are illustrated in  FIG.  1 F . Referring again to  FIG.  1 F , in some aspects, the 5G network  140 F may include a management system (or management service)  190 , which is configured to offer management capabilities within the 5G network  140 F. These management capabilities may be accessed by management service consumers via a service interface (e.g.,  196 ), which may be composed of individually specified management service components. In this regard, the management system  190  may be configured to communicate with each of the NFs as well as other network entities within the network  140 F, except the UE  101  (e.g., including the network entities within the dashed area in  FIG.  1 F ). In some aspects, the management system  190  may be configured based on 3GPP TS 28.533 (v16.0.0). 
     In some aspects, the management system  190  may include management functions (MFs)  192 , . . . ,  194 . In some aspects, at least one of the MFs (e.g., MF  192 ) may be configured as a service producer, performing one or more of the E2E performance measurement functions discussed herein. In some aspects, the service producer (e.g.,  198 ) may be implemented within at least one of the NFs within the 5G network  140 F. 
     In some aspects, the service producer (e.g.,  192 ) can be configured to receive (or retrieve) performance measurements of various network entities within the network  140 F and perform E2E performance measurement calculation  199  to generate E2E performance measurements. In some aspects, E2E measurements performed using techniques disclosed herein can be measurements for a sub-network, for a network slice instance (NSI), for a network slice subnet instance (NSSI), or for the whole network. 
     In some aspects, the following measurement definition template (described in greater detail in 3GPP TS 32.404 V15.0.0) may be used in connection with E2E performance measurements:

Each NF in the 5G network  140   f  may run as a VNF using virtualized resource of the NFVI  306 . The NFV framework  300  may be configured and may include entities as described in connection with one or more European Telecommunications Standards Institute (ETSI) group specifications (GSs), such as ETSI GS NFV 002, ETSI GS NFV-IFA 027, or other ETSI specifications.

     In some aspects, a service producer supported by one or more processors, is configured to obtain the performance measurements of NF(s), calculate E2E performance measurements based on the obtained performance measurements, and generate the end to end performance measurements. The E2E performance measurements are for a subnetwork, an NSI, or an NSSI. The subnetwork is represented by the Managed Object Instance (MOI) of a subnetwork. The NSI is represented by the MOI of a network slice. The NSSI is represented by the MOI of a network slice subnet. The E2E performance measurement includes an average E2E latency. The average E2E latency is accumulation of average DL delay on air-interface, average DL delay in RAN (e.g., the sum of average DL delay in gNB-DU, average DL IP latency in gNB-DU, average DL delay on F1-U, average DL delay in CU-UP), the average delay on N3, the average delay on N9, the average delay on N6, the average latency in PDF(s).

The mean VR usage of NF is mean virtual CPU usage, mean virtual memory usage, or mean virtual disk usage. The NF is one or more of gNB, gNB-CU, gNB-CUCP, gNB-CUUP, AMF, SMF, UPF, N3IWF, PCF, AUSF, UDM, UDR, NRF, NSSF, SMSF, LMF, NWDAF, NGEIR or SEPP.

     In some aspects, a service producer supported by one or more processors generates the mean VR usage by receiving the VR usage measurements for VNFC instance(s) from VNFM, mapping the measured object of each received measurement from VNFC instance to MOI of the measured NF, and taking weighted average of the VR usage measurements whose measured object(s) are mapped to the MOI of the measured NF. The VR usage measurement received from the VNFM is VcpuUsageMeanVnf.vComputeId, VmemoryUsageMeanVnf.vComputeId or VdiskUsageMeanVnf.vComputeId. 
       FIG.  4    illustrates a block diagram of a communication device such as an evolved Node-B (eNB), a next generation Node-B (gNB), an access point (AP), a wireless station (STA), a mobile station (MS), or a user equipment (UE), in accordance with some aspects and to perform one or more of the techniques disclosed herein. In alternative aspects, the communication device  400  may operate as a standalone device or may be connected (e.g., networked) to other communication devices. 
     Circuitry (e.g., processing circuitry) is a collection of circuits implemented intangible entities of the device  400  that include hardware (e.g., simple circuits, gates, logic, etc.). Circuitry membership may be flexible over time. Circuitries include members that may, alone or in combination, perform specified operations when operating. In an example, the hardware of the circuitry may be immutably designed to carry out a specific operation (e.g., hardwired). In an example, the hardware of the circuitry may include variably connected physical components (e.g., execution units, transistors, simple circuits, etc.) including a machine-readable medium physically modified (e.g., magnetically, electrically, moveable placement of invariant massed particles, etc.) to encode instructions of the specific operation. 
     In connecting the physical components, the underlying electrical properties of a hardware constituent are changed, for example, from an insulator to a conductor or vice versa. The instructions enable embedded hardware (e.g., the execution units or a loading mechanism) to create members of the circuitry in hardware via the variable connections to carry out portions of the specific operation when in operation. Accordingly, in an example, the machine-readable medium elements are part of the circuitry or are communicatively coupled to the other components of the circuitry when the device is operating. In an example, any of the physical components may be used in more than one member of more than one circuitry. For example, under operation, execution units may be used in a first circuit of a first circuitry at one point in time and reused by a second circuit in the first circuitry, or by a third circuit in a second circuitry at a different time. Additional examples of these components with respect to the device  400  follow. 
     In some aspects, the device  400  may operate as a standalone device or may be connected (e.g., networked) to other devices. In a networked deployment, the communication device  400  may operate in the capacity of a server communication device, a client communication device, or both in server-client network environments. In an example, the communication device  400  may act as a peer communication device in peer-to-peer (P2P) (or other distributed) network environment. The communication device  400  may be a UE, eNB, PC, a tablet PC, a STB, a PDA, a mobile telephone, a smartphone, a web appliance, a network router, switch or bridge, or any communication device capable of executing instructions (sequential or otherwise) that specify actions to be taken by that communication device. Further, while only a single communication device is illustrated, the term “communication device” shall also be taken to include any collection of communication devices that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein, such as cloud computing, software as a service (SaaS), and other computer cluster configurations. 
     Examples, as described herein, may include, or may operate on, logic or a number of components, modules, or mechanisms. Modules are tangible entities (e.g., hardware) capable of performing specified operations and may be configured or arranged in a certain manner. In an example, circuits may be arranged (e.g., internally or with respect to external entities such as other circuits) in a specified manner as a module. In an example, the whole or part of one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware processors may be configured by firmware or software (e.g., instructions, an application portion, or an application) as a module that operates to perform specified operations. In an example, the software may reside on a communication device-readable medium. In an example, the software, when executed by the underlying hardware of the module, causes the hardware to perform the specified operations. 
     Accordingly, the term “module” is understood to encompass a tangible entity, be that an entity that is physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operation described herein. Considering examples in which modules are temporarily configured, each of the modules need not be instantiated at any one moment in time. For example, where the modules comprise a general-purpose hardware processor configured using software, the general-purpose hardware processor may be configured as respective different modules at different times. The software may accordingly configure a hardware processor, for example, to constitute a particular module at one instance of time and to constitute a different module at a different instance of time. 
     Communication device (e.g., UE)  400  may include a hardware processor  402  (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory  404 , a static memory  406 , and mass storage  407  (e.g., hard drive, tape drive, flash storage, or other block or storage devices), some or all of which may communicate with each other via an interlink (e.g., bus)  408 . 
     The communication device  400  may further include a display device  410 , an alphanumeric input device  412  (e.g., a keyboard), and a user interface (UI) navigation device  414  (e.g., a mouse). In an example, the display device  410 , input device  412  and UI navigation device  414  may be a touchscreen display. The communication device  400  may additionally include a signal generation device  418  (e.g., a speaker), a network interface device  420 , and one or more sensors  421 , such as a global positioning system (GPS) sensor, compass, accelerometer, or another sensor. The communication device  400  may include an output controller  428 , such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate or control one or more peripheral devices (e.g., a printer, card reader, etc.). 
     The storage device  407  may include a communication device-readable medium  422 , on which is stored one or more sets of data structures or instructions  424  (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. In some aspects, registers of the processor  402 , the main memory  404 , the static memory  406 , and/or the mass storage  407  may be, or include (completely or at least partially), the device-readable medium  422 , on which is stored the one or more sets of data structures or instructions  424 , embodying or utilized by any one or more of the techniques or functions described herein. In an example, one or any combination of the hardware processor  402 , the main memory  404 , the static memory  406 , or the mass storage  416  may constitute the device-readable medium  422 . 
     As used herein, the term “device-readable medium” is interchangeable with “computer-readable medium” or “machine-readable medium”. While the communication device-readable medium  422  is illustrated as a single medium, the term “communication device-readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions  424 . 
     The term “communication device-readable medium” is inclusive of the terms “machine-readable medium” or “computer-readable medium”, and may include any medium that is capable of storing, encoding, or carrying instructions (e.g., instructions  424 ) for execution by the communication device  400  and that cause the communication device  400  to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions. Non-limiting communication device-readable medium examples may include solid-state memories and optical and magnetic media. Specific examples of communication device-readable media may include: non-volatile memory, such as semiconductor memory devices (e.g., Electrically Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; Random Access Memory (RAM); and CD-ROM and DVD-ROM disks. In some examples, communication device-readable media may include non-transitory communication device-readable media. In some examples, communication device-readable media may include communication device-readable media that is not a transitory propagating signal. 
     The instructions  424  may further be transmitted or received over a communications network  426  using a transmission medium via the network interface device  420  utilizing any one of a number of transfer protocols. In an example, the network interface device  420  may include one or more physical jacks (e.g., Ethernet, coaxial, or phone jacks) or one or more antennas to connect to the communications network  426 . In an example, the network interface device  420  may include a plurality of antennas to wirelessly communicate using at least one of single-input-multiple-output (SIMO), MIMO, or multiple-input-single-output (MISO) techniques. In some examples, the network interface device  420  may wirelessly communicate using Multiple User MIMO techniques. 
     The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding or carrying instructions for execution by the communication device  400 , and includes digital or analog communications signals or another intangible medium to facilitate communication of such software. In this regard, a transmission medium in the context of this disclosure is a device-readable medium. 
     A communication device-readable medium may be provided by a storage device or other apparatus which is capable of hosting data in a non-transitory format. In an example, information stored or otherwise provided on a communication device-readable medium may be representative of instructions, such as instructions themselves or a format from which the instructions may be derived. This format from which the instructions may be derived may include source code, encoded instructions (e.g., in compressed or encrypted form), packaged instructions (e.g., split into multiple packages), or the like. The information representative of the instructions in the communication device-readable medium may be processed by processing circuitry into the instructions to implement any of the operations discussed herein. For example, deriving the instructions from the information (e.g., processing by the processing circuitry) may include: compiling (e.g., from source code, object code, etc.), interpreting, loading, organizing (e.g., dynamically or statically linking), encoding, decoding, encrypting, unencrypting, packaging, unpackaging, or otherwise manipulating the information into the instructions. 
     In an example, the derivation of the instructions may include assembly, compilation, or interpretation of the information (e.g., by the processing circuitry) to create the instructions from some intermediate or preprocessed format provided by the machine-readable medium. The information, when provided in multiple parts, may be combined, unpacked, and modified to create the instructions. For example, the information may be in multiple compressed source code packages (or object code, or binary executable code, etc.) on one or several remote servers. The source code packages may be encrypted when in transit over a network and decrypted, uncompressed, assembled (e.g., linked) if necessary, and compiled or interpreted (e.g., into a library, stand-alone executable etc.) at a local machine, and executed by the local machine. 
     Although an aspect has been described with reference to specific exemplary aspects, it will be evident that various modifications and changes may be made to these aspects without departing from the broader scope of the present disclosure. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense. This Detailed Description, therefore, is not to be taken in a limiting sense, and the scope of various aspects is defined only by the appended claims, along with the full range of equivalents to which such claims are entitled.
