     DETAILED DESCRIPTION 
     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 that 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. 
     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 phrases “A or B” and “A and/or B” mean (A), (B), or (A and B). For the purposes of the present disclosure, the phrases “A, B, or C” and “A, B, and/or C” mean (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. 
     As used herein, the term “circuitry” may refer to, be part of, or include any combination of integrated circuits (for example, a field-programmable gate array (FPGA), an application specific integrated circuit (ASIC), etc.), discrete circuits, combinational logic circuits, system on a chip (SOC), system in a package (SiP), that provides the described functionality. In some embodiments, the circuitry may execute one or more software or firmware modules to provide the described functions. In some embodiments, circuitry may include logic, at least partially operable in hardware. 
     In Long Term Evolution (LTE) communications, while a reference signal is received by a UE, a receiver (Rx) chain may measure, for example, a reference signal received power (RSRP) referenced at the antenna connector of the Rx chain. Then, the UE may determine a value to indicate the measured RSRP based on pre-determined tables and report that value. When more than one Rx chain are used for receiver diversity, individual Rx chains may generate individual values corresponding to individual RSRPs measured at individual Rx chains. Then, the reported value shall not be lower than the corresponding RSRP of any of the individual diversity branches, according to 3rd Generation Partnership Project (3GPP) Technical Specification (TS) 36.214 v14.2.0 (Mar. 23, 2017). Another example is measuring reference signal receive quality (RSRQ) referenced at the antenna connector of the Rx chain. Complete definitions for RSRP and RSRQ in TS 36.214 are detailed in Table 1 and Table 2, respectively. Similar implementations are used for measurements of received signal strength indicator (RSSI) and reference signal-signal to noise and interference ratio (RS-SINR).

     Various embodiments describe apparatuses, methods, and storage media for configuring measurements of a reference signal received by a UE while the UE may utilize one or more antenna panels for beamforming. In fifth generation (5G) new radio (NR) communications, a UE may utilize beamforming techniques for receiving and/or transmitting signals, especially while operating at millimeter wave (mmWave) frequency and sub mmWave frequency. An antenna panel may include a plurality of antennas or antenna elements that form one or more beams, so that an antenna gain or beamforming gain may improve the receiving signal power level to enhance the UE&#39;s receiving capability. Thus, reference signals may be measured as receive-beamformed signals. Individual Rx chains may further receive such receive-beamformed signals after the beamforming process by the antenna panel. In some embodiments, more than one panel may be used. It is noted that antennas and antenna elements are used interchangeably herein. 
       FIG.  1    schematically illustrates an example wireless network  100  (hereinafter “network  100 ”) in accordance with various embodiments herein. The network  100  may include a UE  105  wirelessly communicated with one eNB  110 . In some embodiments, the network  100  may be a 5G NR network, a radio access network (RAN) of a third generation partnership project (3GPP) LTE network, such as evolved universal terrestrial radio access network (E-UTRAN), a NextGen RAN (NG RAN), or some other type of RAN. The UE  105  may be configured to connect, for example, to be communicatively coupled, with the eNB  110 . In this example, the connection  112  is illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols such as a 5G NR protocol operating at mmWave and sub-mmWave, 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, and the like. 
     The UE  105  is illustrated as a smartphone (for example, a handheld touchscreen mobile computing device connectable to one or more cellular networks), but may also comprise any mobile or non-mobile computing devices, such as a Personal Data Assistant (PDA), pager, laptop computer, desktop computer, wireless handset, or any computing device including a wireless communications interface. In some embodiments, the UE  105  can comprise a narrowband Internet of Things (NB-IoT) UE, which can comprise a network access layer designed for low-power NB-IoT applications utilizing short-lived UE connections. An NB-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 NB-IoT/MTC network describes interconnecting NB-IoT/MTC UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure), with short-lived connections. The NB-IoT/MTC UEs may execute background applications (for example, keep-alive message, status updates, location related services, etc.). 
     The eNB  110  can enable or terminate the connection  112 . The eNB  110  can be referred to as a base station (BS), NodeB, evolved NodeB (eNB), next Generation NodeB (gNB), RAN node, serving cell, and so forth, and can comprise ground stations (for example, terrestrial access points) or satellite stations providing coverage within a geographic area (for example, a cell). 
     The eNB  110  can be the first point of contact for the UE  105 . In some embodiments, the eNB  110  can fulfill various logical functions 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 some embodiments, a downlink resource grid can be used for downlink transmissions from any of the RAN nodes, for example, the eNB  110  to the UE  105 , 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 orthogonal frequency division multiplexing (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 UE  105 . 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 UE  105  about the transport format, resource allocation, and hybrid automatic repeat request (HARQ) information related to the uplink shared channel. Typically, downlink scheduling (assigning control and shared channel resource blocks to the UE  105  within a cell) may be performed at the eNB  110  based on channel quality information fed back from any of the UE  105 . The downlink resource assignment information may be sent on the PDCCH used for (for example, assigned to) the UE  105 . 
     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 (for example, aggregation level, L=1, 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 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.

In other embodiments, the baseband circuitry  125  may be implemented in separate chips or modules, for example, one chip including the transmit circuitry  135  and another chip including the receive circuitry  145 . 
     In some embodiments, the UE  105  may include similar circuitry components as illustrated above, but suitable for operating at sub-mmWave frequency. In one example, mmWave refers to a frequency range above 24 GHz and sub-mmWave refers to a frequency range above microwave frequency and below 24 GHz. It is noted that the range of mmWave and sub-mmWave are not dictated by one particular number, but are used for distinguishing from existing LTE operation below 6 GHz.

The plurality of antennas  210  may constitute one or more antenna panels for beamforming. The components of the illustrated device  200  may be included in a UE or an eNB. In some embodiments, the device  200  may include fewer elements (for example, an eNB may not utilize the application circuitry  202 , and instead include a processor/controller to process IP data received from an evolved packet core (EPC)). In some embodiments, the device  200  may include additional elements such as, for example, a memory/storage, display, camera, sensor, or input/output (I/O) interface.

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  200 . In some embodiments, processors of application circuitry  202  may process IP data packets received from an EPC.

The baseband circuitry  204  (for example, one or more of baseband processors  204 A-D) may handle various radio control functions that enable communication with one or more radio networks via the RF circuitry  206 . In other embodiments, some or all of the functionality of baseband processors  204 A-D may be included in modules stored in the memory  204 G and executed via a central processing unit (CPU)  204 E. The radio control functions may include, but are not limited to, signal modulation/demodulation, encoding/decoding, radio frequency shifting, etc. In some embodiments, modulation/demodulation circuitry of the baseband circuitry  204  may include Fast-Fourier Transform (FFT), precoding, or constellation mapping/demapping functionality. In some embodiments, encoding/decoding circuitry of the baseband circuitry  204  may include convolution, tail-biting convolution, turbo, Viterbi, or Low Density Parity Check (LDPC) encoder/decoder functionality. Embodiments of modulation/demodulation and encoder/decoder functionality are not limited to these examples and may include other suitable functionality in other embodiments. 
     In some embodiments, the baseband circuitry  204  may include one or more audio digital signal processor(s) (DSP)  204 F. The audio DSP(s)  204 F 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, in 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  204  and the application circuitry  202  may be implemented together such as, for example, on a SOC. 
     In some embodiments, the baseband circuitry  204  may provide for communication compatible with one or more radio technologies. For example, in some embodiments, the baseband circuitry  204  may support communication with an evolved universal terrestrial radio access network (E-UTRAN) 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  204  is configured to support radio communications of more than one wireless protocol may be referred to as multi-mode baseband circuitry. 
     RF circuitry  206  may enable communication with wireless networks using modulated electromagnetic radiation through a non-solid medium.

     In some dual-mode embodiments, a separate radio integrated circuit (IC) circuitry may be provided for processing signals for each spectrum, although the scope of the embodiments is not limited in this respect. 
     RFFE circuitry  208  may include a receive signal path, which may include circuitry configured to operate on RF signals received from one or more antennas  210  and beamformed by a panel of the antennas  210  while operating at millimeter wave frequency, amplify the received signals and provide the amplified versions of the received signals to the RF circuitry  206  for further processing. RFFE circuitry  208  may also include a transmit signal path, which may include circuitry configured to amplify signals for transmission provided by the RF circuitry  206  for transmission by one or more of the antennas  210 , with or without beamforming. In various embodiments, the amplification through transmit or receive signal paths may be done solely in the RF circuitry  206 , solely in the RFFE  208 , or in both the RF circuitry  206  and the RFFE  208 . 
     In some embodiments, the RFFE circuitry  208  may include a TX/RX switch to switch between transmit mode and receive mode operation.

The RFFE  305  may be similar to and substantially interchangeable with the RFFE  208  in some embodiments. 
     In this embodiment, the one or more sub-mmWave RFICs  310  (or simply “RFICs  310 ”) may be physically separated from the mmWave RFFE  305 . RFICs  310  may include connection to one or more antennas  320 . RFFE  305  may be coupled with multiple antennas  315 , which may constitute one or more antenna panels.

RFFE  330  may incorporate both millimeter wave antennas  335  and sub-millimeter wave antennas  340 . The RFFE  330  may be similar to and substantially interchangeable with the RFFE  208  in some embodiments. 
       FIG.  4    schematically illustrates an exemplary RF receiver (Rx) circuitry  400  according to some embodiments. The Rx circuitry  400  may be similar to the RFFE  208 , the receiver circuitry  206 A, or a combination thereof.  FIG.  4    may schematically illustrate how a receive beam is formed and processed by an RF front end and receiver circuitry. 
     RF Rx circuitry  400  may include one or more RF Rx paths  405 , which in some embodiments may include one or more antennas, filters, low noise amplifiers, programmable phase shifters and power supplies (not shown). In some embodiments, each RF Rx path  405  may include or be coupled to an antenna panel comprising multiple antenna elements that may form a receive beam. The antenna panel may be similar to and substantially interchangeable with the antenna panel  165  in  FIG.  1   . An RF Rx path  405  may be coupled with a receiver branch for further received signal processing. 
     In some embodiments, multiple RF Rx paths  405  may be coupled to one antenna panel to form receive beams. RF Rx circuitry  400  may include power combining circuitry  410  in some embodiments. In some other embodiments, power combining circuitry  410  may operate bidirectionally, such that the same physical circuitry may be configured to operate as a power divider when the device is transmitting, and as a power combiner when the device is receiving.  FIG.  4    focuses on the power combining aspect from the UE reception perspective. In some embodiments, power combining circuitry  410  may include wholly or partially separate circuitries to perform power combining when the device is receiving. In some embodiments, power combining circuitry  410  may include passive circuitry comprising one or more two-way power combiners arranged in a tree. In some embodiments, power combining circuitry  410  may include active circuitry comprising amplifier circuits. 
     In some embodiments, RF Rx circuitry  400  may be coupled with one or more receiver branches. A combined RF path interface  415  may connect a power combining circuitry  410  to a receiver branch  420 . Multiple receiver branches may be connected to multiple power combining circuitry  410  via multiple combined RF path interfaces  415 . One or more receiver branches  420  may constitute the receiver circuitry  206 A. 
     In LTE, as aforementioned, RSRP may be used for measuring the received power level of a reference signal to indicate signal strength from one or more cells. RSRQ, RSSI and/or RS-SINR may be alternatively or additionally used for similar purposes. For simplicity of the discussion, only RSRP is illustrated as an example, but all the descriptions herein apply to the other reference signal measurements, as well as, but not limited to, RSRQ, RSSI and RS-SINR. 
     RSRP is defined as the linear average over the power contribution in Watt of the resource elements received at each antenna connector, which is associated with each receiver branch. When one or more diversity receiver branches are in use by the UE, the reported value shall not be lower than the corresponding RSRP of any of the individual diversity branches, according to TS 36.214. 
     In NR with respect to mmWave and/or sub-mmWave operation, receiver beamforming may be used by a UE receiver. In beamforming, each antenna of an antenna panel may receive a reference signal with respect to a cell. Two or more antennas of the panel may be in use for beamforming. The antennas may shift phases on individual received reference signals. The shifted phases may have different degrees corresponding to respective antennas in order to achieve a desired antenna gain for the received reference signal. The assigned phase shifts may be different due to different reference signal receive patterns, which may be affected by multiple factors, such as a UE location, frequency band and channel bandwidth, interference, etc. Once a receive beam is formed by the antenna panel, the receive beam may be received and further processed by a receiver branch. With respect to the same reference signal regarding a specific cell, more than one beam may be formed by the antenna panel. Then, a linear average over the receive beams in power measurements (measured in Waft) may be used to calculate the power level of the reference signal with respect to the same antennas associated with the same receiver branch. For an instance of RSRP, a corresponding value may be reported based on the calculation on the received power of the beams. Thus, both the UE and eNB may have knowledge of the received power level with respect to a receiver branch. Therefore, the UE and eNB may determine further operations based on this information. 
     In some embodiments, one or more diversity receiver branches may be implemented to enhance UE receiving capability. For example, a UE may have a number of 2×N receiving antennas (N is an integer and larger than 2). Then a number of N antennas may be used to form Rx beam 1 and another number of N antennas may be used to form Rx beam 2. The RSRP of Rx beam 1 is value x, and the RSRP of Rx beam 2 is value y. Then, the reported value of RSRP may be equal to the maximized value of x and y. Multiple diversity receiver branches may be used so that more than two RSRP values may be generated by measurements. Then the maximum value among all of the RSRP values may be reported to indicate the UE&#39;s RSRP regarding the particular cell. 
     In some embodiments, a UE may have one or more diversity receiver branches to receive multiple Rx beams, so that multiple RSRP values may be generated by RSRP measurements. Then an averaged value calculated based on all of the RSRP values may be reported. For example, values x, y, and z may be determined from RSRP measurements with respect to three beams received by three groups of antennas. The reported value may be calculated by averaging all three of them, (x+y+z)/3. 
     In some other embodiments, among multiple RSRP values, only a number of largest RSRP values but not all of the values may be used for averaging. For example, RSRP values x, y, and z have a relationship that z&gt;y&gt;x, and only the top two of the values may be used for averaging. Then the reported value may be calculated based on (z+y)/2. 
     In some embodiments, RSRQ, RSSI and/or RS-SINR may be used in a manner similar to that described above with respect to RSRP. In various embodiments, the reference signals may be primary synchronization signal (PSS), secondary synchronization signal (SSS), channel-state information reference signal (CSI-RS), demodulation reference signal (DM-RS), Phase tracking reference signal (PT-RS), cell-specific reference signal (CRS), and new radio reference signal (NR-RS). 
     In some embodiments, a UE may have one panel of antenna elements to form one or more Rx beams. Alternatively, a UE may have multiple panels of antenna elements to form multiple Rx beams. One or more panels may feed into one or more receiver branches. 
       FIG.  5 A  illustrates an operation flow/algorithmic structure  500  to facilitate a process of reference signal measurements by the UE  105  in accordance with some embodiments. The operation flow/algorithmic structure  500  may be performed by the UE  105  or circuitry thereof. 
     The operation flow/algorithmic structure  500  may include, at  510 , forming a receive beam of the received reference signal by an antenna panel. The reference signal may be transmitted by an eNB  110  with respect to a cell. In some embodiments, forming the receive beam may include the one or more baseband processors controlling an RFFE  208  and the antenna panel to generate the receive beam. For example, the baseband circuitry may control respective phase shifting at each antenna element to achieve desired antenna gains. In some embodiments, multiple beams may be received by one panel of antennas. In some other embodiments, more than one receiver branch may be used for receiving. Therefore, more than one antenna panel may form more than one receive beam, which may be further received and processed by corresponding receiver branches. Receive beams may be receive-beamformed reference signals. In some embodiments, the reference signals may be PSS, SSS, CSI-RS, DM-RS, PT-RS, CRS, and NR-RS. 
     The operation flow/algorithmic structure  500  may further include, at  520 , measuring receive-beamformed reference signals by the one or more baseband processors. The measurement may be referenced for individual receiver branches. In some embodiments, RSRP, RSRQ, RSSI and/RS-SINR may be used for reference signal measurement. 
     The operation flow/algorithmic structure  500  may further include, at  530 , determining one or more values to indicate respective measured receive-beamformed reference signals or measured receive beams with respect to individual receiver branches by a CPU coupled with the one or more baseband processors. In some embodiments, only one receiver branch may be used for receiving the one or more receiver beams. Then, only one corresponding value may be determined and reported accordingly. In some other embodiments, more than one receiver branch may be used for receiving more than one receiver beam. Thus, more than one value may be determined. 
     The operation flow/algorithmic structure  500  may further include, at  540 , generating a baseband signal to report the value. This may be performed by the one or more baseband processors coupled with the CPU. In some embodiments, the CPU coupled with the one or more baseband processors may generate a report to include the value. In some embodiments, a maximum value of all the determined values may be reported. In another example, the reported value may not be lower than any of the determined values. In some other embodiments, the reported value may be an average value of all the determined values based on an averaging calculation. In some other embodiments, a number of the determined values may be selected for the averaging calculation. The number of determined values to be selected may be predetermined and equal to or larger than two, and the selected values are the largest values among all the determined values. The generated baseband signal may be transmitted to the eNB  110  as described above. 
       FIG.  5 B  illustrates an operation flow/algorithmic structure  505  to facilitate the process of reference signal measurements by the eNB  110  in accordance with some embodiments. The operation flow/algorithmic structure  505  may be performed by the eNB  110  or circuitry thereof, for example, baseband circuitry. 
     The operation flow/algorithmic structure  505  may include, at  515 , transmitting a reference signal. In some embodiments, the reference signals may be PSS, SSS, CSI-RS, DM-RS, PT-RS, CRS, and NR-RS. 
     The operation flow/algorithmic structure  505  may further include, at  525 , processing a baseband signal that includes the reported value from the UE  105 . 
       FIG.  6    illustrates example interfaces of baseband circuitry in accordance with some embodiments. As discussed above, the baseband circuitry  204  of  FIG.  2    may comprise processors  204 A- 204 E and a memory  204 G utilized by said processors. Each of the processors  204 A- 204 E may include a memory interface,  604 A- 604 E, respectively, to send/receive data to/from the memory  204 G. 
     The baseband circuitry  204  may further include one or more interfaces to communicatively couple to other circuitries/devices, such as a memory interface  612  (for example, an interface to send/receive data to/from memory external to the baseband circuitry  204 ), an application circuitry interface  614  (for example, an interface to send/receive data to/from the application circuitry  202  of  FIG.  2   ), an RF circuitry interface  616  (for example, an interface to send/receive data to/from RF circuitry  206  of  FIG.  2   ), a wireless hardware connectivity interface  618  (for example, an interface to send/receive data to/from Near Field Communication (NFC) components, Bluetooth® components (for example, Bluetooth® Low Energy), Wi-Fi® components, and other communication components), and a power management interface  620  (for example, an interface to send/receive power or control signals). 
       FIG.  7    is a block diagram illustrating components, according to some example embodiments, able to read instructions from a machine-readable or computer-readable medium (for example, a non-transitory machine-readable storage medium) and perform any one or more of the methodologies discussed herein. Specifically,  FIG.  7    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 .
