[0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 63 / 028,105, entitled "Wireless Communications Using Multiple Antenna Arrays and a Lens Array," filed May 21, 2020, by Horn et al.; and U.S. Patent Application No. 17 / 315,941, entitled "Wireless Communications Using Multiple Antenna Arrays and a Lens Array," filed May 10, 2021, by Horn et al., wherein each of the U.S. patent applications is assigned to the assignee of this application. Technical Field
[0003] The following text generally refers to wireless communication, and more specifically, to wireless communication using multiple antenna arrays and lens arrays. Background Technology
[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of these multiple access systems include fourth-generation (4G) systems such as Long Term Evolution (LTE), LTE-A Advanced (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Spectrum Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as User Equipment (UE).
[0005] Some wireless communication systems (such as NR systems) can use high-frequency signals to form directional communication links to transmit data or other information. For example, an antenna element array can be configured to generate and guide beams in different directions by manipulating the phase and / or amplitude relationships between signals transmitted or received by the individual antenna elements of the array, and each beam can correspond to a directional communication link. In some cases, such an antenna element array may be referred to as a phased array antenna. Communicating via multiple communication links can increase throughput, but increasing the number of concurrent beams supported by the antenna element array can increase the number of components (e.g., more antenna elements, phase shifters, or other components) or introduce other complexities or drawbacks. Summary of the Invention
[0006] The described technology relates to improved methods, systems, devices, and apparatuses for supporting wireless communication using multiple antenna arrays and lens arrays. Thus, the apparatus may include multiple antenna element arrays and multiple lenses. Each individual antenna element array may include a collection of antenna elements and associated phase-shifting circuitry. The multiple lenses can be configured as lens arrays of any configuration, such as a one-dimensional (1D) lens array (e.g., a linear arrangement of lenses) or a two-dimensional (2D) lens array (e.g., multiple rows and columns of lenses).
[0007] Each antenna element array can individually and concurrently generate multiple beams (for transmitting or receiving signals) in multiple different directions. For example, each antenna element array can concurrently generate different beams pointing towards different lenses of a lens array (e.g., a first beam pointing towards a first lens, a second beam pointing towards a second lens, etc.). If two antenna element arrays concurrently point their beams towards the same lens, the lenses can maintain separation (e.g., orthogonality) between the beams (e.g., as perceived on the other side of the lens) because the two antenna element arrays have different physical positions relative to the focal plane of the lens. Therefore, for example, combining M antenna element arrays, each capable of individually supporting at least N concurrent beam directions, with a lens array comprising at least N lenses, can support up to M*N concurrent beams, and thus support M*N concurrent directional communication links.
[0008] An apparatus for wireless communication is described. The apparatus may include a lens array comprising a first lens and a second lens.

[0044] Wireless communication between two devices via multiple directional communication links (e.g., beams) can provide, for example, throughput benefits (e.g., increased peak data rates) or reliability benefits (e.g., due to spatial diversity between beams and therefore between links). In some cases, an array of antenna elements can be used to form a beam, but many antenna elements can be used within a single array to form multiple close beams, and beams from multiple arrays in similar directions may interfere with each other.
[0045] The structures and techniques described herein can provide various many-to-many solutions in which multiple antenna element arrays operate in conjunction with multiple lenses (e.g., lens arrays) at a single transmitting or receiving device within a wireless communication system. For simplicity, a single antenna element array may be referred to herein alternatively as an antenna element array or antenna array. For example, an antenna array may be a phased antenna array. In some cases, each of the M antenna arrays at the device may individually support at least N concurrent (e.g., at least partially overlapping in time) beams in different directions, and at least N lenses may be present in the lens array at the device. For each of the M antenna arrays, each of the N beam directions may correspond to (e.g., point to) a different lens in the lens array. Thus, each antenna array may be individually capable of simultaneously pointing different beams to different lenses in the lens array (e.g., for each of the M antenna arrays, at least one corresponding beam points to each lens in the lens array, such that up to at least M beams can simultaneously point to any one lens in the lens array). If two antenna arrays simultaneously point their respective beams at the same lens, the lens can maintain separation (e.g., orthogonality) between the beams, for example because the two antenna arrays can have different physical positions relative to the focal plane of the lens. Therefore, the wireless device described herein can simultaneously support at least M*N directional communication links.
[0046] Advantageously, using multiple antenna arrays can support multiple beams and thus multiple links in the direction of a single lens, which can provide throughput or other benefits. As another example, using a lens array (e.g., relative to a single lens) can improve the coverage radius relative to the set of supported beams (e.g., enhanced spherical coverage can be obtained). Alternatively or additionally, the number of antenna elements per antenna array can be reduced while maintaining beam shape (e.g., compactness) and link separation (or the number of antenna elements per antenna array can be maintained while improving beam shape), as lenses can facilitate beamforming and beam splitting. For example, an antenna array can generate a relatively wide beam that can be focused (e.g., tightened) by a lens, such that a narrower beam is generated on the opposite side of the lens relative to the antenna array. Furthermore, the use of antenna arrays can provide improved transmit power per beam (e.g., relative to using lenses to focus other omnidirectional transmissions). Further or alternative benefits associated with the teachings herein will be appreciated by those skilled in the art.
[0047] The aspects of this disclosure are first described in the context of wireless communication systems. These aspects are further illustrated and described with reference to diagrams and flowcharts relating to wireless communication using multiple antenna arrays and lens arrays.
[0048] Figure 1Examples of a wireless communication system 100 supporting wireless communication using multiple antenna arrays and lens arrays according to various aspects of this disclosure are shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE network, an LTE-A network, an LTE-A Pro network, or an NR network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.
[0049] Base stations 105 can be distributed throughout a geographic area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110 over which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographic area over which base station 105 and UE 115 can support communication of signals according to one or more radio access technologies.
[0050] UE 115 can be distributed throughout the entire coverage area 110 of wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices with different forms or different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein can be used with various types of devices (e.g., other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 (As shown) to communicate.
[0051] Base station 105 may communicate with core network 130, or with each other, or both. For example, base station 105 may interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) or directly and indirectly on backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.
[0052] One or more base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home eNodeB or other suitable terms.
[0053] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscription device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, which may be implemented in various objects such as home appliances, vehicles, or meters.
[0054] The UE 115 described in this document can communicate with various types of devices, such as other UEs 115 that can sometimes act as repeaters, as well as base station 105 and network devices (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations), etc. Figure 1 As shown.
[0055] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. In some cases, communication link 125 may include one or more directional communication links as described herein. The term "carrier" may refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of radio spectrum band (e.g., bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating the operation of the carrier, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with frequency division duplex (FDD) and time division duplex (TDD) component carriers.
[0056] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or DFT-S-OFDM). In a system employing MCM, a resource element can consist of one symbol period (e.g., the duration of a modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate that can be used for the UE 115. Wireless communication resources can refer to a combination of radio spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with the UE 115.
[0057] The time interval used for base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time intervals of communication resources can be organized based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0058] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame (e.g., in the time domain) may be divided into multiple subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple mini-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or frequency band of the operation.
[0059] A subframe, time slot, mini-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).
[0060] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for the physical control channel can be defined by the number of symbol periods and can be extended over the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESET) can be configured for a set in UE 115. For example, one or more UEs in UE 115 can monitor or search control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates from one or more aggregation levels arranged in a concatenated manner. The aggregation level for the control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set configured to send control information to a specific UE 115.
[0061] In some examples, base station 105 may be mobile, and thus provide communication coverage for mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.
[0062] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services such as Mission-Critical Talk-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.
[0063] In some examples, UE 115 may also be able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using point-to-point (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication may employ a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.
[0064] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), User Plane Function (UPF)) routing packets or interconnects to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Operator IP service 150 can include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0065] Some network devices (e.g., base station 105) may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).
[0066] Wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. The region from 300 MHz to 3 GHz is generally referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is from approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be sufficient to penetrate structures to allow macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer wavelengths in the High Frequency (HF) or Extreme High Frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).
[0067] Wireless communication system 100 may use licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands may be based on carrier aggregation configuration combined with component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.
[0068] Base station 105 or UE 115 may be equipped with multiple antennas (e.g., multiple antenna arrays) that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be located together at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.
[0069] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.
[0070] Beamforming, also known as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105 or UE 115) to shape or guide (e.g., point or otherwise orient) an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while others experience destructive interference. Adjustment of the signals transmitted via the antenna elements can include the transmitting or receiving device applying amplitude, phase shift, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each antenna element can be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation). As described herein, in some cases, beamforming can be further achieved by using a lens array, wherein the lenses of the array can shape (e.g., tighten, focus) beams toward or from the antenna array, and can maintain separation (e.g., orthogonality) between beams toward or from different antenna arrays.
[0071] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device (such as base station 105) or a receiving device (such as UE 115)) the beam direction for later transmission or reception by base station 105.
[0072] Some signals (such as data signals associated with a particular receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more of a plurality of signals transmitted by base station 105 in different directions, and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or otherwise with acceptable signal quality.
[0073] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to the configured number of beams across the system bandwidth or one or more subbands. Base station 105 can transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may or may not be precoded. UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).
[0074] When receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by: receiving via different antenna subarrays; processing the received signal according to different antenna subarrays; receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights); or processing the received signal according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned on a beam direction determined based on listening according to different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).
[0075] Wireless devices (e.g., base station 105, relay device, UE 115, or other devices configured to transmit or receive wireless signals) may include lens arrays and multiple antenna arrays (e.g., each antenna array includes multiple antenna elements). Each of the multiple antenna arrays may individually support (e.g., be able to generate and guide) multiple beams in different directions. For example, each antenna array may be able to guide at least one beam at each lens of the lens array (e.g., concurrently). Thus, in some cases, multiple concurrent beams may pass through (e.g., point through) the lens, wherein at least some of the multiple concurrent beams are associated with different antenna arrays in the multiple antenna arrays. The lens may tighten or otherwise refine the beams passing through the lens. Additionally or alternatively, the lens may maintain separation (e.g., orthogonality) between different beams passing through the lens simultaneously. In some cases, the wireless device may concurrently guide multiple beams, wherein the multiple beams may go to or come from the same antenna array or from different antenna arrays. Multiple beams can be associated with one or more other wireless devices (e.g., pointed to or from one or more other wireless devices in order to exchange signaling with one or more other wireless devices).
[0076] Figure 2 An example configuration 200 of multiple antenna arrays and lens arrays according to various aspects of this disclosure is shown. Configuration 200 may include multiple antenna arrays 205 and a lens array including multiple lenses 215. Although in Figure 2 The example shows four antenna arrays 205 and four lenses 215, but it should be understood that any number of antenna arrays and any number of lenses are possible.
[0077] Antenna array 205 may include multiple antenna elements for generating or otherwise guiding beam 210 in multiple different directions (e.g., concurrently). Associated circuitry (e.g., radio frequency circuitry) may also be included. For example, antenna array 205 may include phase shifters, and each phase shifter may be configured to adjust the phase or one or more other properties of a signal transmitted or received via a corresponding antenna element of antenna array 205. In some cases, the phase shifters of the antenna array may be arranged as a group referred to as layers, and each beam for antenna array 205 may correspond to a different phase shifter layer (e.g., generated by or otherwise guided by different phase shifter layers), such that the number of phase shifter layers at antenna array 205 may correspond to the number of concurrent beam directions supported by antenna array 205. Although Figure 2 The example shows each antenna array 205 as supporting four beam directions, but it should be understood that, depending on the implementation, the antenna array 205 can support any number of beam directions.
[0078] Antenna array 205 is capable of directing one or more beams 210 to any lens 215 within the lens array, or alternatively to any lens 215 within a subset of lenses 215 in the lens array. As an example, antenna array 205-a may be capable of directing beam 210-a to lens 215-b and (e.g., simultaneously) directing beam 210-c to lens 215-d. Although not all possible beams 210 supported by example configuration 200 are shown for clarity of illustration, antenna array 205-a may also be capable of (e.g., concurrently) directing another beam 210 to lens 215-a and another beam 210 to lens 215-c (e.g., at each lens 215, each antenna array 205 may be capable of concurrently directing at least one beam). Any number of other antenna arrays 205 may also be able to direct beam 210 toward lens 215 of the lens array, possibly concurrently with antenna array 205-a. For example, as Figure 2 As shown, antenna array 205-b can guide beam 210-b to lens 215-b, and antenna array 205-a concurrently guides beam 210-a to lens 215-b.
[0079] The lenses 215 of the lens array can be arranged in any configuration. For example, the lens array can be a 1D lens array, and the lenses 215 in the lens array can be arranged in rows, columns, or other linear configurations (e.g., arranged). As another example, the lens array can be a 2D lens array, and the lenses 215 in the lens array can be arranged as a collection of rows and columns, a rectangular array, or otherwise span at least two dimensions (e.g., a horizontal dimension and a vertical dimension). In some cases, the device may include more than one lens array 215. The use of multiple lenses can provide an enhanced coverage radius or area (e.g., enhanced spherical coverage) through configuration 200. In the case of using a 2D lens array, the antenna array 205 can be configured to support 2D beamforming. For example, the antenna array 205 may include a 2D phase shifter, and the antenna elements of the antenna array 205 may be configured as a uniform rectangular array (URA) or other 2D array.
[0080] In some cases, lens 215 can facilitate beamforming (e.g., beam shaping). For example, lens 215 can refine (e.g., tighten, collimate, or otherwise focus or improve) the beam 210 passing through (e.g., traversing) lens 215. As another example, lens 215 can help maintain separation (e.g., orthogonality) between different beams 210 that concurrently pass through lens 215. For example, lens 215 can change the plane wave angle (e.g., orientation) associated with the beam passing through lens 215. For example, when antenna array 205 transmits or receives beam 210 passing through lens 215, the lens can change the plane wave angle of the beam based on the physical position of antenna array 205 relative to the focal plane. Therefore, if both antenna arrays 205 transmit or receive beams 210 through the same lens 215, the lens 215 can make the beams 210 have different plane wave angles that are received by the two antenna arrays 205 or by one or more other target devices, even if, for example, the associated phase shifters at the two different antenna arrays 205 are configured the same.
[0081] exist Figure 2 In the example, example configuration 200 may be included at base station 105, and base station 105 may communicate with other wireless devices, such as UE 115. For example, base station 105 may communicate with UE 115-d via a first directional communication link corresponding to beam 210-a (which may be transmitted or received by antenna array 205-a and passes through lens 215-b), and may communicate with UE 115-c via a second directional communication link corresponding to beam 210-b (which may be transmitted or received by antenna array 205-b and also passes through lens 215-b) (e.g., concurrently). Additionally or alternatively, base station 105 may communicate with UE 115-e via a third directional communication link corresponding to beam 210-c (which may be transmitted or received by antenna array 205-a and passes through lens 215-d) (e.g., concurrently). In some cases, base station 105 can communicate with a single UE 115 via multiple beams 210 (e.g., via multiple beams 210 transmitted or received by different antenna arrays 205), potentially enabling MIMO configuration.
[0082] In some cases, any combination of antenna array 205 and lens 215 can be supported (e.g., concurrently). For example, a wireless device may include M antenna arrays 205 and N lenses 215. Each antenna array 205 may support up to at least N concurrent beams 210, where one beam 210 points to each of the N lenses 215. Thus, up to at least M beams can pass through each lens 215 simultaneously, where each of the M beams 210 passes through a given lens 215 corresponding to a different antenna array 205. In some cases, wireless devices as described herein may support a total of M*N concurrent beams (and thus support M*N concurrent directional communication links).
[0083] In some cases, as described herein, a wireless device can support beam tracking while communicating with another wireless device because the physical location of the other wireless device can change relative to the wireless device, as described herein. When the relative physical location of the other wireless device changes but remains within the aperture of the same lens 215, the wireless device, as described herein, can switch from communicating with the other wireless device using one antenna array 205 to communicating with the other wireless device using a different antenna array 205. For example, at the first moment, UE 115 may be located in... Figure 2 The example illustrates the location of UE 115-d, and base station 105 can communicate with UE 115 using antenna array 205-a and beam 210-a passing through lens 215-b. However, UE 115 can move, so that at a second time, UE 115 can be physically located... Figure 2 The example illustration shows the location of UE115-c. At a second time, base station 105 can communicate with UE 115 using antenna array 205-b and beam 210-b passing through lens 215-b. Therefore, even if there is relative movement of UE 115 but UE 115 remains within the aperture of the same lens 215, base station 105 can switch antenna array 205 without switching the lens 215 used for communication with UE 115.
[0084] When the relative physical location of another wireless device changes such that the other wireless device enters the aperture of the second lens 215 (and may also leave the aperture of the first lens 215), the wireless device described herein can maintain communication with the other wireless device by changing the beam direction associated with the antenna array 205 (e.g., phase shifter configuration). For example, and continuing the example from the previous paragraph, UE 115 can arrive at a third time at a location physically located... Figure 2The example illustration shows the position of UE 115e. At a third time, base station 105 can communicate with UE 115 using antenna array 205-a and beam 210-c passing through lens 215-d. Therefore, in the event that relative movement of UE 115 causes UE 115 to leave the aperture of one lens 215 or otherwise enter the aperture of another lens 215, the base station can rely on different beam directions supported by the same antenna array 205 but pointing towards different lenses 215 to maintain communication with UE 115.
[0085] Generally, beam tracking can be performed based on any combination of switching between antenna arrays 205 or between lenses 215 (e.g., based on different beam directions associated with the same or different antenna arrays 205) to maintain communication with another wireless device within the aperture of at least one lens of the lens array 215. In some cases, control circuitry can be coupled to the antenna array 205 to manage or otherwise implement beam tracking operation.
[0086] In some cases, the distance from antenna array 205 to lens 215 (e.g., the distance between antenna array 205 and the lens 215 closest to it) may be equal to or greater than the far-field length 220 of antenna array 205. In some cases, the distance between antenna arrays 205 of the wireless device may be configured (e.g., calibrated) to optimize or otherwise configure the degree of beam separation of beams 210 associated with different (e.g., adjacent) antenna arrays 205. Therefore, in some cases, the distance between antenna arrays 205 of the wireless device may depend on the diameter of one or more lenses 215 of the lens array at the wireless device.
[0087] Furthermore, in some cases, the aperture of lens 215 can be optimized or otherwise configured to maximize or otherwise enhance the amount of energy captured by lens 215 for each beam 210 supported by one or more of the antenna arrays 205. For example, the aperture of lens 215 can be configured to capture the maximum or substantially maximum aperture of each main lobe associated with each beam 210. In some cases, the lens diameter 225 of lens 215 can be greater than or equal to the width 230 of the antenna array, wherein the width 230 of the antenna array 205 can correspond to the distance between the outer edge of the antenna element of antenna array 205 and the farthest outer edge of the farthest other antenna element of antenna array 205. Additionally or alternatively, the number of lenses 215 can, in some cases, be equal to or less than the number of beam directions (e.g., concurrent beam directions) supported by a single antenna array 205. In some cases, the number of beam directions supported by a single antenna array 205 can depend on the granularity associated with the phase shifter within the single antenna array 205 (e.g., the number of bits used to control or otherwise configure the phase shift implemented by the single phase shifter).
[0088] In some cases, a wireless device may be able to activate or deactivate (e.g., turn on or off) different antenna elements within antenna array 205, and thus use a variable number of antenna elements to transmit or receive signals to support different levels of power consumption. For example, to support reduced power consumption, a wireless device may deactivate one or more antenna elements at one or more edges of antenna array 205, or may deactivate every other antenna element or some other interleaved subset of antenna elements within antenna array 205. Antenna elements operable to be deactivated may, for example, be coupled to a switch operable to activate or deactivate the antenna element.
[0089] The antenna array 205, lens 215, and other aspects of the wireless device described herein can be configured to be reciprocal (e.g., maintaining a level above a reciprocity threshold relative to transmitted and received signals (e.g., relative to downlink and uplink communications)). For example, the antenna array 205 can all be configured to be reciprocal relative to the transmission and reception of signals. As such an example, transmissions performed by the antenna array 205 can use amplitude distributions or other parameters obtained from or otherwise based on one or more signals received by the antenna array 205.
[0090] Although this document describes some examples from the perspective of a base station including multiple antenna arrays 205 and multiple lenses 215, it should be understood that, in accordance with the teachings of this document, any device that transmits or receives wireless signals (e.g., a relay device, UE 115 (e.g., a vehicle or other type of UE 115)) can be configured to include and employ multiple antenna arrays 205 and multiple lenses 215.

Device 305 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).
[0092] Receiver 310 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to wireless communication using multiple antenna arrays and lens arrays). This information can be passed to other components of device 305. Receiver 310 can be a reference. Figure 6 Examples of various aspects of the transceiver 620 described herein. Receiver 310 may employ a single antenna or a set of antennas. For example, receiver 310 may be coupled to or include an array of antenna arrays 205 as described herein.
[0093] Transmitter 320 can transmit signals generated by other components of device 305. In some examples, transmitter 320 can be co-located with receiver 310 in a transceiver module. For example, transmitter 320 can be a reference... Figure 6 Examples of various aspects of the transceiver 620 described herein. The transmitter 320 may employ a single antenna or a group of antennas. For example, the transmitter 320 may be coupled to or comprise an array of antenna arrays 205 as described herein.
[0094] Communication manager 315 can guide a first beam between a first antenna element array and a first lens in a lens array, wherein the first antenna element array is one of a set of antenna element arrays, and guide a second beam between a first antenna element array and a second lens in a lens array. Communication manager 315 may be an example of various aspects of communication manager 610 described herein.
[0095] The communication manager 315 or its sub-components may be implemented in hardware, processor-executable code (e.g., software or firmware), or any combination thereof. If implemented in processor-executable code, the functionality of the communication manager 315 or its sub-components may be performed by a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described in this disclosure.
[0096] The communication manager 315 or its subcomponents may be physically located in various locations, including being distributed such that portions of the functionality are implemented by one or more physical components in different physical locations.

[0097] The communication manager 315 as described herein can be implemented to achieve one or more potential advantages. One implementation may allow device 405 to perform beamforming and beamguiding operations more efficiently. For example, device 405 may be configured with a lens array and one or more antenna arrays to perform communication with one or more other devices, wherein the lens array can collimate a wide beam transmitted from a small number of antenna elements into a narrow beam.
[0098] Based on the implementation of the lens array and antenna array configuration as described herein, the device's processor (e.g., controls receiver 310, transmitter 320, or reference) Figure 6 The transceiver 620 described can add spherical coverage, increase or decrease array gain, and enhance throughput in the implementation of lens array and antenna array beamforming and beamguiding devices.
[0099] Figure 4 Figure 400 illustrates a device 405 supporting wireless communication using multiple antenna arrays and lens arrays according to various aspects of this disclosure. Device 405 may be an example of aspects of device 305 or base station 105 as described herein. Device 405 may include a receiver 410, a communication manager 415, and a transmitter 430. Device 405 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).
[0100] Receiver 410 can receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to wireless communication using multiple antenna arrays and lens arrays). This information can be passed to other components of device 405. Receiver 410 can be a reference. Figure 6 Examples of various aspects of the transceiver 620 described herein. Receiver 410 may utilize a single antenna or a set of antennas. For example, receiver 410 may be coupled to or include an antenna array set 205 as described herein.
[0101] Transmitter 430 can transmit signals generated by other components of device 405. In some examples, transmitter 430 may be co-located with receiver 410 in a transceiver module. For example, transmitter 430 may be a reference... Figure 6 Examples of various aspects of the transceiver 620 described herein. The transmitter 430 may employ a single antenna or a set of antennas. For example, the transmitter 430 may be coupled to or include an antenna array assembly 205 as described herein.
[0102] Communication manager 415 may be an example of aspects of communication manager 315 as described herein. Communication manager 415 may include a first beamguide module 420 and a second beamguide module 425. Communication manager 415 may be an example of aspects of communication manager 610 as described herein.
[0103] The first beam guiding module 420 can guide a first beam between a first antenna element array and a first lens in a lens array, wherein the first antenna element array is one of a set of antenna element arrays. The second beam guiding module 425 can guide a second beam between the first antenna element array and a second lens in a lens array.
[0104] Figure 5 Figure 500 illustrates a communication manager 505 supporting wireless communication using multiple antenna arrays and lens arrays according to various aspects of this disclosure. Communication manager 505 may be an example of aspects of communication manager 315, communication manager 415, or communication manager 610 described herein. Communication manager 505 may include a beam guidance module 510, a motion identification module 515, a target transmit power identifier 520, and an antenna number changing module 525. Each of these modules may communicate with each other directly or indirectly (e.g., via one or more buses).
[0105] The beam guiding module 510 can guide a first beam between a first antenna element array and a first lens in a lens array, wherein the first antenna element array is one antenna element array in a set of antenna element arrays. The beam guiding module 510 can guide a second beam between the first antenna element array and a second lens in the lens array. The beam guiding module 510 can guide a third beam between a second antenna element array and the first lens, wherein the second antenna element array is another antenna element array in a set of antenna element arrays.
[0106] In some cases, a third beam is guided between the second antenna element array and the first lens, while a first beam is guided between the first antenna element array and the first lens. In some examples, the beam guidance module 510 can communicate with the first UE via the first beam. In some examples, the beam guidance module 510 can communicate with the first UE via a second beam.
[0107] In some examples, beamguiding module 510 enables the wireless device to communicate with the UE via a first beam. Motion identification module 515 can identify the movement of the UE. In some examples, beamguiding module 510 enables the wireless device to communicate with the UE via a third beam after communicating with the UE via the first beam, based on the movement of the UE.
[0108] In some examples, the motion identification module 515 can identify a second movement of the UE. In some examples, the beamguiding module 510 can enable the wireless device to communicate with the UE via a second beam based on the second movement of the UE, after communicating with the UE via a third beam.
[0109] In some cases, a second beam is guided between the first antenna element array and the second lens, while a first beam is guided between the first antenna element array and the first lens. In some examples, the beam guiding module 510 enables a wireless device to communicate with a first UE via the first beam. In some examples, the beam guiding module 510 enables a wireless device to communicate with a second UE via a second beam.
[0110] In some examples, beamguiding module 510 enables a wireless device to communicate via a first beam using a first number of antenna elements within a first antenna element array during a first time period. Beamguiding module 510 enables a wireless device to communicate via a fourth beam using a second number of antenna elements within the first antenna element array during a second time period.
