Detailed Description

Embodiments herein may include transmission of an uplink (UL) measurement configuration to a user equipment (UE), identification of a UL reference signal from the UE, and signal measurement of the UL reference signal. An apparatus may include circuitry to acquire a UL reference signal configuration from a next generation Node B (gNB) or an evolved Node B (eNB), and send a UL reference signal configured at least in part based on the UL reference signal configuration.

In the following detailed description, reference is made to the accompanying drawings that form a part hereof, wherein like numerals designate like parts throughout, and in which is shown by way of illustration embodiments in which the subject matter of the present disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of embodiments is defined by the appended claims and their equivalents.

Various operations may be described as multiple discrete actions or operations in turn, in a manner that is most helpful in understanding the claimed subject matter.

However, the order of description should not be construed as to imply that these operations are necessarily order dependent. In particular, these operations may not be performed in the order of presentation. Operations described may be performed in a different order than the described embodiment. Various additional operations may be performed and/or described operations may be omitted in additional embodiments.

For the purposes of the present disclosure, the phrase "A and/or B" means (A), (B), or (A and B). For the purposes of the present disclosure, the phrase "A, B, and/or C" means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C).

The description may use the phrases "in an embodiment," or "in embodiments," which may each refer to one or more of the same or different embodiments. Furthermore, the terms "comprising," "including," "having," and the like, as used with respect to embodiments of the present disclosure, are synonymous.

The term "coupled with," along with its derivatives, may be used herein.

"Coupled" may mean one or more of the following. "Coupled" may mean that two or more elements are in direct physical or electrical contact. However, "coupled" may also mean that two or more elements indirectly contact each other, but yet still cooperate or interact with each other, and may mean that one or more other elements are coupled or connected between the elements that are said to be coupled with each other.

The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail.

Figure 1 schematically illustrates a DL measurement procedure 10 in comparison with a UL measurement procedure 12, in accordance with various embodiments. The DL measurement procedure 10 and the UL measurement procedure 12 are shown in relation to a first cell coverage area 14, which may also be referred to as Cell A, and a second cell coverage area 16, which also may be referred to as Cell B. In legacy long-term evolution (LTE) networks, as shown in the DL measurement procedure 10, eNBs send periodic downlink signals (e.g., a reference signal) and UEs perform measurement on the reference signal to determine if there is a better cell compared to current serving cell. If an event is configured, the UE may send a measurement report to the eNB and may start a handover procedure. In idle mode, the UE may perform cell reselection.

Some embodiments may include another technique (e.g., the UL measurement procedure 12) that switches the role between the network (e.g., a gNB or an eNB) and UE in comparison to the DL measurement procedure 10. In some embodiments, the UE may sound (e.g., send or transmit) a UL reference signal and the network may perform measurement of the UL reference signal. This may be called UL measurement. In some embodiments, the DL measurement procedure 10 and/or the UL measurement procedure 12 may relate to new radio (NR) scenarios for idle mode UE. Based on configuration, the UE may sound some signal (e.g. a sounding reference signal, or SRS) indicated in the UL measurement procedure 12 as an UL measurement signal, after performing

synchronization to the network (e.g., after the sync blocks shown in the UL measurement procedure 12). Although the signal sounded by the UE may be a SRS, any suitable UL reference signal may be used in various embodiments. This synchronization may use primary synchronization symbols, secondary synchronization signals (PSS/SSS), or any other suitable NR design. Then, the UE may wait for the network response, shown as NW response blocks in the UL measurement procedure 12. In some embodiments, if the UE does not receive a response, the UE may step up power and retransmit the signal.

Assuming the network transmission reception point (TRP) (e.g., gNB or eNB) performs measurement on the UE UL signal successfully and sends back a response from the closest TRP, the UE may then check the response to determine if it includes a paging message.

Embodiments herein may relate to the UL measurement procedure 12 and may include network configuration of the UE with a UL measurement configuration, transmission of a UL reference signal configured at least in part based on the UL measurement configuration, measurement of the UL reference signal by the network (e.g., gNB or eNB), a network response to the UE based at least in part on the measurement of the UL reference signal, and/or cell selection or reselection by the UE based at least in part on the network response.

According to various techniques, a network (e.g., a gNB or an eNB) may send a configuration message (e.g., a UL measurement configuration) to the UE when it is connected. The configuration may include a unique SRS and/or other parameters. In some embodiments, the configuration may not include a unique SRS but may utilize collision resolution or an SRS update when UEs with the same SRS are close to each other.

Through such techniques, the network may configure the UE to perform UL measurement. One example for such configuration is shown in Figure 2 that schematically illustrates a UL measurement configuration interaction 60 between a base station (e.g., gNB or eNB), shown as a gNB 62, and a UE 64, in accordance with various embodiments. In some embodiments, the gNB 62 may send a UL measurement configuration to the UE 64 in a first transmission 66. The UE 64 may respond by sending a UL measurement

configuration acknowledgement (ACK) in a second transmission 68. In various embodiments, after UL measurement configuration, the UE 64 may send a UL reference signal to the gNB, the UL reference signal configured at least in part based on the UL measurement configuration sent in the first transmission 66. In some embodiments, the gNB 62 may perform a signal measurement based at least in part on the UL reference signal and may send a response (e.g., NW response of Fig. 1) to the UE 64 based at least in part on the signal measurement. In some embodiments, the UE 64 may perform cell selection or reselection based at least in part on the response from the gNB 62.

In one embodiment, the UL measurement configuration signaling may be sent via radio resource control (RRC) message to the UE 64 during a

RRCconnectionReconfiguration setup message. In another embodiment, the network may send a RRCConnectionReconfiguration message to the UE 64 for such UL measurement configuration. In another embodiment, the network may send a

RRCConnectionReconfiguration message to the UE 64 when the UE 64 performs a RRC release and goes to idle mode.

Alternatively, in some embodiments, a UL measurement configuration message may be configured to the UE 64 as a part of beam management in the medium access control (MAC) layer. In some embodiments, the network may dynamically turn this feature on and off at any given time. In another embodiment, the UL measurement configuration may be configured dynamically in a physical downlink control channel

(PDCCH). In various embodiments, transmission of a UL measurement configuration may be done one or multiple times, and may be performed periodically.

In some embodiments, various combinations of the following parameters may be optionally included in the UL measurement configuration: SRS sequence; timer (duration of the SRS sequence); starting time/frame number (indicates when the UL sounding may start); ending time/frame number (indicates when the UL sounding may end); periodicity (indicates how often the UL sounding may be performed by the UE); subframe index (may be used instead of periodicity to indicate in which of the n subframes the UE may sound the UL signaling); UL resources (indicates where the UE may send the sounding reference within the subframe indicated by the network); periodic indicator (indicates if the UL sounding is periodic or a single-shot request from the network); maximum transmit power (indicates a maximum transmit power the UE may not exceed); TRP transmit power (indicates TRP transmit power for synchronization signal); UE transmit power (indicates UE transmit power for the UL sounding signaling); power step (indicates the power step the UE may use in case the network response is not heard); retransmission delay (indicates how long the UE may wait to retransmit in case of not hearing the network response); maximum retransmission (indicates the maximum number of retransmissions for UL signaling); power estimation algorithm (indicates which power estimation algorithm the UE should use); and/or states in which UL measurement may be applied (e.g., connected, idle, and/or inactive states). In some embodiments, the timer may be used to indicate how long this SRS is valid. When the timer expires, the UE may request an SRS update from the network. In some embodiments, the network may indicate to the UE that a SRS update is not needed.

Figure 3 illustrates an example of a UL measurement configuration 90 using a

RRC message. In some embodiments, the UL measurement configuration 90 may be identified as a ULMeasConfig information element (IE). In some embodiments, the IE ULMeasConfig may specify the UL measurement configuration and may control setup/ release of the UL measurement.

As used herein, the term "circuitry" may refer to, be part of, or include an

Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group), and/or memory (shared, dedicated, or group) that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable hardware components that provide the described functionality.

The baseband circuitry 104 (e.g., one or more of baseband processors 104a-d) may handle various radio control functions that enable communication with one or more radio networks via the RF circuitry 106. The radio control functions may include, but are not limited to, signal modulation/demodulation, encoding/decoding, radio frequency shifting, and the like.

A central processing unit (CPU) 104e of the baseband circuitry 104 may be configured to run elements of the protocol stack for signaling of the PHY, MAC, RLC, PDCP and/or RRC layers. In some embodiments, the baseband circuitry may include one or more audio digital signal processor(s) (DSP) 104f. The audio DSP(s) 104f may include elements for

The CRM 104g may include any combination of various levels of memory /storage including, but not limited to, read-only memory (ROM) having embedded software instructions (e.g., firmware), random access memory (e.g., dynamic random access memory (DRAM)), cache, buffers, etc.). The CRM 104g may be shared among the various processors or dedicated to particular processors. Components of the baseband circuitry 104 may be suitably combined in a single chip, a single chipset, or disposed on a same circuit board in some embodiments. In some embodiments, some or all of the constituent components of the baseband circuitry 104 and the application circuitry 102 may be implemented together, such as, for example, on a system on a chip (SOC).

In some embodiments, the baseband circuitry 104 may provide for communication compatible with one or more radio technologies. For example, in some embodiments, the baseband circuitry 104 may support communication with an E-UTRAN and/or other wireless metropolitan area networks (WMAN), a wireless local area network (WLAN), a wireless personal area network (WPAN). Embodiments in which the baseband circuitry 104 is configured to support radio communications of more than one wireless protocol may be referred to as multi-mode baseband circuitry.

The amplifier circuitry 106b may be configured to amplify the down-converted signals and the filter circuitry 106c may be a low-pass filter (LPF) or band-pass filter (BPF) configured to remove unwanted signals from the down-converted signals to generate output baseband signals. Output baseband signals may be provided to the baseband circuitry 104 for further processing. In some embodiments, the output baseband signals may be zero-frequency baseband signals, although this is not a requirement. In some embodiments, mixer circuitry 106a of the receive signal path may comprise passive mixers, although the scope of the embodiments is not limited in this respect.

In some embodiments, the mixer circuitry 106a of the transmit signal path may be configured to up-convert input baseband signals based on the synthesized frequency provided by the synthesizer circuitry 106d to generate RF output signals for the FEM circuitry 108.

In some embodiments, the synthesizer circuitry 106d may be a fractional -N synthesizer or a fractional N/N+l synthesizer, although the scope of the embodiments is not limited in this respect, as other types of frequency synthesizers may be suitable. For example, synthesizer circuitry 106d may be a delta-sigma synthesizer, a frequency multiplier, or a synthesizer comprising a phase-locked loop with a frequency divider. The synthesizer circuitry 106d may be configured to synthesize an output frequency for use by the mixer circuitry 106a of the RF circuitry 106 based on a frequency input and a divider control input.

In some embodiments, a divider control input (e.g., N) may be determined from a look-up table based on a channel indicated by the application circuitry 102. Synthesizer circuitry 106d of the RF circuitry 106 may include a divider, a delay- locked loop (DLL), a multiplexer and a phase accumulator. In some embodiments, the divider may be a dual modulus divider (DMD) and the phase accumulator may be a digital phase accumulator (DP A). In some embodiments, the DMD may be configured to divide the input signal by either N or N+l (e.g., based on a carry out) to provide a fractional division ratio. In some example embodiments, the DLL may include a set of cascaded, tunable, delay elements, a phase detector, a charge pump and a D-type flip-flop. In these embodiments, the delay elements may be configured to break a VCO period up into Nd equal packets of phase, where Nd is the number of delay elements in the delay line. In this way, the DLL provides negative feedback to help ensure that the total delay through the delay line is one VCO cycle.

In some embodiments, synthesizer circuitry 106d may be configured to generate a carrier frequency as the output frequency, while in other embodiments, the output frequency may be a multiple of the carrier frequency (e.g., twice the carrier frequency, four times the carrier frequency) and used in conjunction with quadrature generator and divider circuitry to generate multiple signals at the carrier frequency with multiple different phases with respect to each other. In some embodiments, the output frequency may be a LO frequency (fLO). In some embodiments, the RF circuitry 106 may include an IQ/polar converter.

The transmit signal path of the FEM circuitry 108 may include a power amplifier (PA) to amplify input RF signals (e.g., provided by RF circuitry 106), and one or more filters to generate RF signals for subsequent transmission (e.g., by one or more of the one or more antennas In some embodiments, the electronic device 100 may include additional elements such as, for example, a display, a camera, one or more sensors, and/or interface circuitry (for example, input/output (I/O) interfaces or buses) (not shown). In embodiments where the electronic device is implemented in or by an eNB or gNB, the electronic device 100 may include network interface circuitry. The network interface circuitry may be one or more computer hardware components that connect electronic device 100 to one or more network elements, such as one or more servers within a core network or one or more other eNBs or gNBs via a wired connection. To this end, the network interface circuitry may include one or more dedicated processors and/or field programmable gate arrays (FPGAs) to communicate using one or more network communications protocols such as X2 application protocol (AP), S I AP, Stream Control Transmission Protocol (SCTP), Ethernet, Point-to-Point (PPP), Fiber Distributed Data Interface (FDDI), and/or any other suitable network communications protocols.

In some embodiments, the electronic device 100 of Figure 4 may be configured to perform one or more processes, techniques, and/or methods as described herein, or portions thereof. One such process is depicted in Figure 5. For example, a process 200 may include: transmitting or causing to transmit, to a UE, a UL measurement

In some embodiments, at the block 202, the UL measurement configuration may be transmitted with RRC signaling during a setup message, a reconfigure message, or a release message. In some embodiments, at the block 202, the UL measurement configuration may be transmitted via beam management, in a physical layer, or in a MAC layer. In some embodiments, at the block 202, the UL measurement configuration may be transmitted via PDCCH.

In some embodiments, at the block 302, the UE may identify the UL measurement configuration in one or more of a beam management signal, a physical layer, a MAC layer, or a PDCCH. In some embodiments, the UL measurement configuration may include one or more of an SRS sequence, a timer duration, a start frame number, an end frame number, a periodicity, a subframe index, a UL resource, a periodic indictor, a maximum transmit power, a TRP transmit power, a UL transmit power, a power step, a retransmission delay, a maximum number of retransmissions, a power estimation algorithm, or an identification of applicable connection states.

Figure 7 illustrates an architecture of a system 400 of a network in accordance with some embodiments. The system 400 is shown to include a user equipment (UE) 401 and a UE 402. The UEs 401 and 402 are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks), but may also comprise any mobile or non-mobile computing device, such as Personal Data Assistants (PDAs), pagers, laptop computers, desktop computers, wireless handsets, or any computing device including a wireless communications interface.

In some embodiments, any of the UEs 401 and 402 can comprise an Internet of Things (IoT) UE, which can comprise a network access layer designed for low-power IoT applications utilizing short-lived UE connections. 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 describes 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.

The UEs 401 and 402 may be configured to connect, e.g., communicatively couple, with a radio access network (RAN) 410— the RAN 410 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 401 and 402 utilize connections 403 and 404, respectively, each of which comprises a physical communications interface or layer (discussed in further detail below); in this example, the connections 403 and 404 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 3 GPP Long Term Evolution (LTE) protocol, a fifth generation (5G) protocol, a New Radio (NR) protocol, and the like.

In this embodiment, the UEs 401 and 402 may further directly exchange communication data via a ProSe interface 405. The ProSe interface 405 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 402 is shown to be configured to access an access point (AP) 406 via connection 407. The connection 407 can comprise a local wireless connection, such as a connection consistent with any IEEE 802.1 1 protocol, wherein the AP 406 would comprise a wireless fidelity (WiFi®) router. In this example, the AP 406 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 410 can include one or more access nodes that enable the connections 403 and 404. These access nodes (ANs) can be referred to as base stations (BSs), NodeBs, evolved NodeBs (eNBs), next Generation NodeBs (gNB), RAN nodes, and so forth, and can comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell). The RAN 410 may include one or more RAN nodes for providing macrocells, e.g., macro RAN node 411 , 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 412.

Any of the RAN nodes 41 1 and 412 can terminate the air interface protocol and can be the first point of contact for the UEs 401 and 402. In some embodiments, any of the RAN nodes 41 1 and 412 can fulfill various logical functions for the RAN 410 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 accordance with some embodiments, the UEs 401 and 402 can be configured to communicate using Orthogonal Frequency -Division Multiplexing (OFDM)

communication signals with each other or with any of the RAN nodes 411 and 412 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 or sidelink communications), although the scope of the embodiments is not limited in this respect. The OFDM signals can comprise a plurality of orthogonal subcarriers.

In some embodiments, a downlink resource grid can be used for downlink transmissions from any of the RAN nodes 411 and 412 to the UEs 401 and 402, 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 is a common practice for OFDM systems, which makes it intuitive for radio resource allocation. Each column and each row of the resource grid corresponds to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to one slot in a radio frame. The smallest time-frequency unit in a resource grid is denoted as a resource element. Each resource grid comprises a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a collection of resource elements; in the frequency domain, this may represent the smallest quantity of resources that currently can be allocated. There are 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 401 and 402. 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 401 and 402 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 41 1 and 412 based on channel quality information fed back from any of the UEs 401 and 402. The downlink resource assignment information may be sent on the PDCCH used for (e.g., assigned to) each of the UEs 401 and 402.

The PDCCH may use control channel elements (CCEs) to convey the control information. Before being mapped to resource elements, the PDCCH complex-valued symbols may first be organized into quadruplets, which may then be permuted using a sub-block interleaver for rate matching. Each PDCCH may be transmitted using one or more of these CCEs, where each CCE may correspond to nine sets of four physical resource elements known as resource element groups (REGs). Four Quadrature Phase Shift Keying (QPSK) symbols may be mapped to each REG. The PDCCH can be transmitted using one or more CCEs, depending on the size of the downlink control information (DCI) and the channel condition. There can be four or more different PDCCH formats defined in LTE with different numbers of CCEs (e.g., aggregation level, L=l, 2, 4, or 8).

Some embodiments may use concepts for resource allocation for control channel information that are an extension of the above-described concepts. For example, some embodiments may utilize an enhanced physical downlink control channel (EPDCCH) that uses PDSCH resources for control information transmission. The EPDCCH may be transmitted using one or more enhanced the control channel elements (ECCEs). Similar to above, each ECCE may correspond to nine sets of four physical resource elements known as an enhanced resource element groups (EREGs). An ECCE may have other numbers of EREGs in some situations.

The RAN 410 is shown to be communicatively coupled to a core network (CN) 420— via an SI interface 413. In embodiments, the CN 420 may be an evolved packet core (EPC) network, a NextGen Packet Core (NPC) network, or some other type of CN. In this embodiment the SI interface 413 is split into two parts: the Sl-U interface 414, which carries traffic data between the RAN nodes 411 and 412 and the serving gateway (S-GW) 422, and the Sl-mobility management entity (MME) interface 415, which is a signaling interface between the RAN nodes 411 and 412 and MMEs 421.

In this embodiment, the CN 420 comprises the MMEs 421, the S-GW 422, the Packet Data Network (PDN) Gateway (P-GW) 423, and a home subscriber server (HSS) 424. The MMEs 421 may be similar in function to the control plane of legacy Serving General Packet Radio Service (GPRS) Support Nodes (SGSN). The MMEs 421 may manage mobility aspects in access such as gateway selection and tracking area list management. The HSS 424 may comprise a database for network users, including subscription-related information to support the network entities' handling of

communication sessions. The CN 420 may comprise one or several HSSs 424, depending on the number of mobile subscribers, on the capacity of the equipment, on the organization of the network, etc. For example, the HSS 424 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc.

The S-GW 422 may terminate the SI interface 413 towards the RAN 410, and routes data packets between the RAN 410 and the CN 420. In addition, the S-GW 422 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.

The P-GW 423 may terminate an SGi interface toward a PDN. The P-GW 423 may route data packets between the EPC network 423 and external networks such as a network including the application server 430 (alternatively referred to as application function (AF)) via an Internet Protocol (IP) interface 425. Generally, the application server 430 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 embodiment, the P-GW 423 is shown to be communicatively coupled to an application server 430 via an IP communications interface 425. The application server 430 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 401 and 402 via the CN 420.

The P-GW 423 may further be a node for policy enforcement and charging data collection. Policy and Charging Enforcement Function (PCRF) 426 is the policy and charging control element of the CN 420. In a non-roaming scenario, there may be a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with a UE's Internet Protocol Connectivity Access Network (IP-CAN) session. In a roaming scenario with local breakout of traffic, there may be two PCRFs associated with a UE's IP-CAN session: a Home PCRF (H-PCRF) within a HPLMN and a Visited PCRF (V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF 426 may be

communicatively coupled to the application server 430 via the P-GW 423. The application server 430 may signal the PCRF 426 to indicate a new service flow and select the appropriate Quality of Service (QoS) and charging parameters. The PCRF 426 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 430.

The components of the illustrated device 500 may be included in a UE or a RAN node. In some embodiments, the device 500 may include less elements (e.g., a RAN node may not utilize application circuitry 502, and instead include a processor/controller to process IP data received from an EPC). In some embodiments, the device 500 may include additional elements such as, for example, memory /storage, display, camera, sensor, or input/output (I/O) interface.

For example, the application circuitry 502 may include circuitry such as, but not limited to, one or more single-core or multi-core processors. The processor(s) may include any combination of general-purpose processors and dedicated processors (e.g., graphics processors, application processors, etc.). The processors may be coupled with or may include memory /storage and may be configured to execute instructions stored in the memory /storage to enable various applications or operating systems to run on the device 500. In some embodiments, processors of application circuitry 502 may process IP data packets received from an EPC.

The baseband circuitry 504 may include circuitry such as, but not limited to, one or more single-core or multi-core processors. The baseband circuitry 504 may include one or more baseband processors or control logic to process baseband signals received from a receive signal path of the RF circuitry 506 and to generate baseband signals for a transmit signal path of the RF circuitry 506. Baseband processing circuity 504 may interface with the application circuitry 502 for generation and processing of the baseband signals and for controlling operations of the RF circuitry 506. For example, in some embodiments, the baseband circuitry 504 may include a third generation (3G) baseband processor 504A, a fourth generation (4G) baseband processor 504B, a fifth generation (5G) baseband processor 504C, or other baseband processor(s) 504D for other existing generations, generations in development or to be developed in the future (e.g., second generation (2G), sixth generation (6G), etc.). The baseband circuitry 504 (e.g., one or more of baseband processors 504A-D) may handle various radio control functions that enable

communication with one or more radio networks via the RF circuitry 506. In other embodiments, some or all of the functionality of baseband processors 504A-D may be included in modules stored in the memory 504G and executed via a Central Processing Unit (CPU) 504E.

The audio DSP(s) 504F may be include elements for compression/decompression and echo cancellation and may include other suitable processing elements in other embodiments. Components of the baseband circuitry may be suitably combined in a single chip, a single chipset, or disposed on a same circuit board in some embodiments. In some embodiments, some or all of the constituent components of the baseband circuitry 504 and the application circuitry 502 may be implemented together such as, for example, on a system on a chip (SOC).

In some embodiments, the baseband circuitry 504 may provide for communication compatible with one or more radio technologies. For example, in some embodiments, the baseband circuitry 504 may support communication with an evolved universal terrestrial radio access network (EUTRAN) or other wireless metropolitan area networks (WMAN), a wireless local area network (WLAN), a wireless personal area network (WPAN).

Embodiments in which the baseband circuitry 504 is configured to support radio communications of more than one wireless protocol may be referred to as multi-mode baseband circuitry.

RF circuitry 506 may enable communication with wireless networks using modulated electromagnetic radiation through a non-solid medium. In various

embodiments, the RF circuitry 506 may include switches, filters, amplifiers, etc. to facilitate the communication with the wireless network. RF circuitry 506 may include a receive signal path which may include circuitry to down-convert RF signals received from the FEM circuitry 508 and provide baseband signals to the baseband circuitry 504. RF circuitry 506 may also include a transmit signal path which may include circuitry to up- convert baseband signals provided by the baseband circuitry 504 and provide RF output signals to the FEM circuitry 508 for transmission.

In some embodiments, the receive signal path of the RF circuitry 506 may include mixer circuitry 506a, amplifier circuitry 506b and filter circuitry 506c. In some embodiments, the transmit signal path of the RF circuitry 506 may include filter circuitry 506c and mixer circuitry 506a. RF circuitry 506 may also include synthesizer circuitry 506d for synthesizing a frequency for use by the mixer circuitry 506a of the receive signal path and the transmit signal path. In some embodiments, the mixer circuitry 506a of the receive signal path may be configured to down-convert RF signals received from the FEM circuitry 508 based on the synthesized frequency provided by synthesizer circuitry 506d. The amplifier circuitry 506b may be configured to amplify the down-converted signals and the filter circuitry 506c may be a low-pass filter (LPF) or band-pass filter (BPF) configured to remove unwanted signals from the down-converted signals to generate output baseband signals. Output baseband signals may be provided to the baseband circuitry 504 for further processing. In some embodiments, the output baseband signals may be zero-frequency baseband signals, although this is not a requirement. In some embodiments, mixer circuitry 506a of the receive signal path may comprise passive mixers, although the scope of the embodiments is not limited in this respect.

In some embodiments, the mixer circuitry 506a of the transmit signal path may be configured to up-convert input baseband signals based on the synthesized frequency provided by the synthesizer circuitry 506d to generate RF output signals for the FEM circuitry 508. The baseband signals may be provided by the baseband circuitry 504 and may be filtered by filter circuitry 506c.

In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a of the transmit signal path may include two or more mixers and may be arranged for quadrature downconversion and upconversion, respectively. In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a of the transmit signal path may include two or more mixers and may be arranged for image rejection (e.g., Hartley image rej ection). In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a may be arranged for direct downconversion and direct upconversion, respectively. In some embodiments, the mixer circuitry 506a of the receive signal path and the mixer circuitry 506a of the transmit signal path may be configured for super-heterodyne operation.

In some embodiments, the output baseband signals and the input baseband signals may be analog baseband signals, although the scope of the embodiments is not limited in this respect. In some alternate embodiments, the output baseband signals and the input baseband signals may be digital baseband signals. In these alternate embodiments, the RF circuitry 506 may include analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuitry and the baseband circuitry 504 may include a digital baseband interface to communicate with the RF circuitry 506.

In some embodiments, the synthesizer circuitry 506d may be a fractional -N synthesizer or a fractional N/N+l synthesizer, although the scope of the embodiments is not limited in this respect as other types of frequency synthesizers may be suitable. For example, synthesizer circuitry 506d may be a delta-sigma synthesizer, a frequency multiplier, or a synthesizer comprising a phase-locked loop with a frequency divider.

The synthesizer circuitry 506d may be configured to synthesize an output frequency for use by the mixer circuitry 506a of the RF circuitry 506 based on a frequency input and a divider control input. In some embodiments, the synthesizer circuitry 506d may be a fractional N/N+l synthesizer.

In some embodiments, frequency input may be provided by a voltage controlled oscillator (VCO), although that is not a requirement. Divider control input may be provided by either the baseband circuitry 504 or the applications processor 502 depending on the desired output frequency. In some embodiments, a divider control input (e.g., N) may be determined from a look-up table based on a channel indicated by the applications processor 502.

Synthesizer circuitry 506d of the RF circuitry 506 may include a divider, a delay- locked loop (DLL), a multiplexer and a phase accumulator. In some embodiments, the divider may be a dual modulus divider (DMD) and the phase accumulator may be a digital phase accumulator (DP A). In some embodiments, the DMD may be configured to divide the input signal by either N or N+l (e.g., based on a carry out) to provide a fractional division ratio. In some example embodiments, the DLL may include a set of cascaded, tunable, delay elements, a phase detector, a charge pump and a D-type flip-flop. In these embodiments, the delay elements may be configured to break a VCO period up into Nd equal packets of phase, where Nd is the number of delay elements in the delay line. In this way, the DLL provides negative feedback to help ensure that the total delay through the delay line is one VCO cycle.

In some embodiments, synthesizer circuitry 506d may be configured to generate a carrier frequency as the output frequency, while in other embodiments, the output frequency may be a multiple of the carrier frequency (e.g., twice the carrier frequency, four times the carrier frequency) and used in conjunction with quadrature generator and divider circuitry to generate multiple signals at the carrier frequency with multiple different phases with respect to each other. In some embodiments, the output frequency may be a LO frequency (fLO). In some embodiments, the RF circuitry 506 may include an IQ/polar converter.

FEM circuitry 508 may include a receive signal path which may include circuitry configured to operate on RF signals received from one or more antennas 510, amplify the received signals and provide the amplified versions of the received signals to the RF circuitry 506 for further processing. FEM circuitry 508 may also include a transmit signal path which may include circuitry configured to amplify signals for transmission provided by the RF circuitry 506 for transmission by one or more of the one or more antennas 510. In various embodiments, the amplification through the transmit or receive signal paths may be done solely in the RF circuitry 506, solely in the FEM 508, or in both the RF circuitry 506 and the FEM 508.

In some embodiments, the FEM circuitry 508 may include a TX/RX switch to switch between transmit mode and receive mode operation. The FEM circuitry may include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry may include an LNA to amplify received RF signals and provide the amplified received RF signals as an output (e.g., to the RF circuitry 506). The transmit signal path of the FEM circuitry 508 may include a power amplifier (PA) to amplify input RF signals (e.g., provided by RF circuitry 506), and one or more filters to generate RF signals for subsequent transmission (e.g., by one or more of the one or more antennas 510).

In some embodiments, the PMC 512 may manage power provided to the baseband circuitry 504. In particular, the PMC 512 may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion. The PMC 512 may often be included when the device 500 is capable of being powered by a battery, for example, when the device is included in a UE. The PMC 512 may increase the power conversion efficiency while providing desirable implementation size and heat dissipation characteristics.

While Figure 8 shows the PMC 512 coupled only with the baseband circuitry 504. However, in other embodiments, the PMC 512 may be additionally or alternatively coupled with, and perform similar power management operations for, other components such as, but not limited to, application circuitry 502, RF circuitry 506, or FEM 508.

In some embodiments, the PMC 512 may control, or otherwise be part of, various power saving mechanisms of the device 500. For example, if the device 500 is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device 500 may power down for brief intervals of time and thus save power.

If there is no data traffic activity for an extended period of time, then the device 500 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The device 500 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The device 500 may not receive data in this state, in order to receive data, it must transition back to

RRC Connected state.

An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.

Processors of the application circuitry 502 and processors of the baseband circuitry 504 may be used to execute elements of one or more instances of a protocol stack. For example, processors of the baseband circuitry 504, alone or in combination, may be used execute Layer 3, Layer 2, or Layer 1 functionality, while processors of the application circuitry 504 may utilize data (e.g., packet data) received from these layers and further execute Layer 4 functionality (e.g., transmission communication protocol (TCP) and user datagram protocol (UDP) layers). As referred to herein, Layer 3 may comprise a radio resource control (RRC) layer, described in further detail below. As referred to herein, Layer 2 may comprise a medium access control (MAC) layer, a radio link control (RLC) layer, and a packet data convergence protocol (PDCP) layer, described in further detail below. As referred to herein, Layer 1 may comprise a physical (PHY) layer of a UE/RAN node, described in further detail below.

Figure 9 illustrates example interfaces of baseband circuitry in accordance with some embodiments. As discussed above, the baseband circuitry 504 of Figure 8 may comprise processors 504A-504E and a memory 504G utilized by said processors. Each of the processors 504A-504E may include a memory interface, 604A-604E, respectively, to send/receive data to/from the memory 504G.

The baseband circuitry 504 may further include one or more interfaces to communicatively couple to other circuitries/devices, such as a memory interface 612 (e.g., an interface to send/receive data to/from memory external to the baseband circuitry 504), an application circuitry interface 614 (e.g., an interface to send/receive data to/from the application circuitry 502 of Figure 8), an RF circuitry interface 616 (e.g., an interface to send/receive data to/from RF circuitry 506 of Figure 8), a wireless hardware connectivity interface 618 (e.g., an interface to send/receive data to/from Near Field Communication (NFC) components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components), and a power management interface 620 (e.g., an interface to send/receive power or control signals to/from the PMC 512.

Figure 10 is a block diagram illustrating components, according to some example embodiments, able to read instructions from a machine-readable or computer-readable medium (e.g., a non-transitory machine-readable storage medium) and perform any one or more of the methodologies discussed herein. Specifically, Figure 10 shows a

diagrammatic representation of hardware resources 700 including one or more processors (or processor cores) 710, one or more memory /storage devices 720, and one or more communication resources 730, each of which may be communicatively coupled via a bus 740. For embodiments where node virtualization (e.g., NFV) is utilized, a hypervisor 702 may be executed to provide an execution environment for one or more network slices/sub- slices to utilize the hardware resources 700

The processors 710 (e.g., a central processing unit (CPU), a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a graphics processing unit (GPU), a digital signal processor (DSP) such as a baseband processor, an application specific integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC), another processor, or any suitable combination thereof) may include, for example, a processor 712 and a processor 714. The memory /storage devices 720 may include main memory, disk storage, or any suitable combination thereof. The memory /storage devices 720 may include, but are not limited to any type of volatile or non-volatile memory such as dynamic random access memory (DRAM), static random-access memory (SRAM), erasable programmable read- only memory (EPROM), electrically erasable programmable read-only memory

(EEPROM), Flash memory, solid-state storage, etc.

The communication resources 730 may include interconnection or network interface components or other suitable devices to communicate with one or more peripheral devices 704 or one or more databases 706 via a network 708. For example, the communication resources 730 may include wired communication components (e.g., for coupling via a Universal Serial Bus (USB)), cellular communication components, NFC components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components.

Instructions 750 may comprise software, a program, an application, an applet, an app, or other executable code for causing at least any of the processors 710 to perform any one or more of the methodologies discussed herein. The instructions 750 may reside, completely or partially, within at least one of the processors 710 (e.g., within the processor's cache memory), the memory /storage devices 720, or any suitable combination thereof.
