Title: Beamforming architecture capability signaling

Description:
FIELD OF THE DISCLOSURE 
     Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for beamforming architecture capability signaling. 
     BACKGROUND 
     Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). 
     A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station. 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. 
     Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G). 
       FIG.  1    is a diagram illustrating an example of a wireless network  100 , in accordance with the present disclosure. The wireless network  100  may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network  100  may include one or more base stations  110  (shown as a BS  110   a , a BS  110   b , a BS  110   c , and a BS  110   d ), a user equipment (UE)  120  or multiple UEs  120  (shown as a UE  120   a , a UE  120   b , a UE  120   c , a UE  120   d , and a UE  120   e ), and/or other network entities. A base station  110  is an entity that communicates with UEs  120 . A base station  110  (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station  110  may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station  110  and/or a base station subsystem serving this coverage area, depending on the context in which the term is used. 
     A base station  110  may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs  120  with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs  120  with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs  120  having association with the femto cell (e.g., UEs  120  in a closed subscriber group (CSG)). A base station  110  for a macro cell may be referred to as a macro base station. A base station  110  for a pico cell may be referred to as a pico base station. A base station  110  for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in  FIG.  1   , the BS  110   a  may be a macro base station for a macro cell  102   a , the BS  110   b  may be a pico base station for a pico cell  102   b , and the BS  110   c  may be a femto base station for a femto cell  102   c . A base station may support one or multiple (e.g., three) cells. 
     In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station  110  that is mobile (e.g., a mobile base station). In some examples, the base stations  110  may be interconnected to one another and/or to one or more other base stations  110  or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network. 
     The wireless network  100  may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station  110  or a UE  120 ) and send a transmission of the data to a downstream station (e.g., a UE  120  or a base station  110 ). A relay station may be a UE  120  that can relay transmissions for other UEs  120 . In the example shown in  FIG.  1   , the BS  110   d  (e.g., a relay base station) may communicate with the BS  110   a  (e.g., a macro base station) and the UE  120   d  in order to facilitate communication between the BS  110   a  and the UE  120   d . A base station  110  that relays communications may be referred to as a relay station, a relay base station, a relay, or the like. 
     The wireless network  100  may be a heterogeneous network that includes base stations  110  of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations  110  may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network  100 . For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts). 
     A network controller  130  may couple to or communicate with a set of base stations  110  and may provide coordination and control for these base stations  110 . The network controller  130  may communicate with the base stations  110  via a backhaul communication link. The base stations  110  may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. 
     The UEs  120  may be dispersed throughout the wireless network  100 , and each UE  120  may be stationary or mobile. A UE  120  may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE  120  may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium. 
     Some UEs  120  may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs  120  may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs  120  may be considered a Customer Premises Equipment. A UE  120  may be included inside a housing that houses components of the UE  120 , such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled. 
     In general, any number of wireless networks  100  may be deployed in a given geographic area. Each wireless network  100  may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed. 
     In some examples, two or more UEs  120  (e.g., shown as UE  120   a  and UE  120   e ) may communicate directly using one or more sidelink channels (e.g., without using a base station  110  as an intermediary to communicate with one another). For example, the UEs  120  may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE  120  may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station  110 . 
     Devices of the wireless network  100  may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network  100  may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. 
     The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band. 
     With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges. 
     In some aspects, the UE  120  may include a communication manager  140 . As described in more detail elsewhere herein, the communication manager  140  may transmit, to a base station, an indication of a capability of a beamforming architecture of the network device; and communicate with the base station based at least in part on the capability of the beamforming architecture of the network device. Additionally, or alternatively, the communication manager  140  may perform one or more other operations described herein. 
     In some aspects, the base station  110  may include a communication manager  150 . As described in more detail elsewhere herein, the communication manager  150  may receive, from a network device, an indication of a capability of a beamforming architecture of the network device; and communicate with the network device based at least in part on the capability of the beamforming architecture of the network device. Additionally, or alternatively, the communication manager  150  may perform one or more other operations described herein. 
     As indicated above,  FIG.  1    is provided as an example. Other examples may differ from what is described with regard to  FIG.  1   . 
       FIG.  2    is a diagram illustrating an example  200  of a base station  110  in communication with a UE  120  in a wireless network  100 , in accordance with the present disclosure. The base station  110  may be equipped with a set of antennas  234   a  through  234   t , such as T antennas (T≥1). The UE  120  may be equipped with a set of antennas  252   a  through  252   r , such as R antennas (R≥1). 
     At the base station  110 , a transmit processor  220  may receive data, from a data source  212 , intended for the UE  120  (or a set of UEs  120 ). The transmit processor  220  may select one or more modulation and coding schemes (MCSs) for the UE  120  based at least in part on one or more channel quality indicators (CQIs) received from that UE  120 . The base station  110  may process (e.g., encode and modulate) the data for the UE  120  based at least in part on the MCS(s) selected for the UE  120  and may provide data symbols for the UE  120 . The transmit processor  220  may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor  220  may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor  230  may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems  232  (e.g., T modems), shown as modems  232   a  through  232   t . For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem  232 . Each modem  232  may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem  232  may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems  232   a  through  232   t  may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas  234  (e.g., T antennas), shown as antennas  234   a  through  234   t.    
     At the UE  120 , a set of antennas  252  (shown as antennas  252   a  through  252   r ) may receive the downlink signals from the base station  110  and/or other base stations  110  and may provide a set of received signals (e.g., R received signals) to a set of modems  254  (e.g., R modems), shown as modems  254   a  through  254   r . For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem  254 . Each modem  254  may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem  254  may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector  256  may obtain received symbols from the modems  254 , may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor  258  may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE  120  to a data sink  260 , and may provide decoded control information and system information to a controller/processor  280 . The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE  120  may be included in a housing  284 . 
     The network controller  130  may include a communication unit  294 , a controller/processor  290 , and a memory  292 . The network controller  130  may include, for example, one or more devices in a core network. The network controller  130  may communicate with the base station  110  via the communication unit  294 . 
     One or more antennas (e.g., antennas  234   a  through  234   t  and/or antennas  252   a  through  252   r ) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of  FIG.  2   . 
     On the uplink, at the UE  120 , a transmit processor  264  may receive and process data from a data source  262  and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor  280 . The transmit processor  264  may generate reference symbols for one or more reference signals. The symbols from the transmit processor  264  may be precoded by a TX MIMO processor  266  if applicable, further processed by the modems  254  (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station  110 . In some examples, the modem  254  of the UE  120  may include a modulator and a demodulator. In some examples, the UE  120  includes a transceiver. The transceiver may include any combination of the antenna(s)  252 , the modem(s)  254 , the MIMO detector  256 , the receive processor  258 , the transmit processor  264 , and/or the TX MIMO processor  266 . The transceiver may be used by a processor (e.g., the controller/processor  280 ) and the memory  282  to perform aspects of any of the methods described herein (e.g., with reference to  FIGS.  4 - 10   ). 
     At the base station  110 , the uplink signals from UE  120  and/or other UEs may be received by the antennas  234 , processed by the modem  232  (e.g., a demodulator component, shown as DEMOD, of the modem  232 ), detected by a MIMO detector  236  if applicable, and further processed by a receive processor  238  to obtain decoded data and control information sent by the ULE  120 . The receive processor  238  may provide the decoded data to a data sink  239  and provide the decoded control information to the controller/processor  240 . The base station  110  may include a communication unit  244  and may communicate with the network controller  130  via the communication unit  244 . The base station  110  may include a scheduler  246  to schedule one or more UEs  120  for downlink and/or uplink communications. In some examples, the modem  232  of the base station  110  may include a modulator and a demodulator. In some examples, the base station  110  includes a transceiver. The transceiver may include any combination of the antenna(s)  234 , the modem(s)  232 , the MIMO detector  236 , the receive processor  238 , the transmit processor  220 , and/or the TX MIMO processor  230 .

     The controller/processor  240  of the base station  110 , the controller/processor  280  of the UE  120 , and/or any other component(s) of  FIG.  2    may perform one or more techniques associated with beamforming architecture capability signaling, as described in more detail elsewhere herein.

The memory  242  and the memory  282  may store data and program codes for the base station  110  and the UE  120 , respectively. In some examples, the memory  242  and/or the memory  282  may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station  110  and/or the UE  120 , may cause the one or more processors, the UE  120 , and/or the base station  110  to perform or direct operations of, for example, process  700  of  FIG.  7   , process  800  of  FIG.  8   , and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

     As indicated above,  FIG.  2    is provided as an example. Other examples may differ from what is described with regard to  FIG.  2   . 
     In millimeter wave systems, such as FR2 and higher frequency bands (e.g., FR4 and/or FR5), base stations, UEs, and other network devices often use multiple antennas. Beamforming from multiple antennas may be used to bridge a link budget in such millimeter wave systems. In some examples, a network device (e.g., a UE, a base station, and/or another network device) may be equipped with multiple antenna modules/panels having a set of antenna elements that can be co-phased to perform beamforming. For example, the use of multiple antenna modules may enable a network device to meet spherical coverage requirements with or without hand/body blockage, and may increase robustness of coverage with beam switching over the antenna modules. 
     Beamforming may be increasingly applied in large antenna systems, as use of higher frequency millimeter wave operating bands (e.g., FR4 and/or FR5) increases. For example, in a higher frequency millimeter wave operating band (e.g., FR4 and/FR5), a larger antenna system may be deployed in a network device, as compared with FR2, in a same size aperture. Furthermore, within FR2, larger antenna systems may also be deployed as the use of aperture constraint-less systems, such as intelligent reflecting surface (IRS) nodes, repeater nodes, and/or integrated access and backhaul (IAB) nodes, among other examples, increases. 
     In some examples, a UE (or other network device) may perform beamforming using a vector sum modulator phase shifting architecture. A vector sum modulator may include customizable phase shifters (e.g., a 360 degree phase is divided into 2 B  levels/stages for a B-bit phase shifter) and/or customizable amplitude/gain control (e.g., with B amp -bit gain control) over different antenna elements. For example, a vector sum modulator may utilize a 3 or a 5-bit phase shifter to optimize performance with cost. A vector sum modulator-based beamforming architecture may allow adaptability in beamforming codebooks. For example, in a vector sum modulator-based beamforming architecture, arbitrary beam weights that correspond to steerability of a beam&#39;s main lobe, adaptation of a beamwidth of the beam&#39;s main lobe, side lobe levels, and/or multi-beams, among other examples, can be achieved by using different beam weights (e.g., amplitudes and phases), without any change in the beamforming architecture, subject to quantization constraints alone. 
     In some examples, a UE (or other network device) may perform beamforming using a Butler matrix phase shifting architecture. The Butler matrix architecture may produce a set of fixed and orthogonal beams. For example, in a Butler matrix beamforming architecture, a set of possible beams may be a set of beams separated by progressive phase shifts (PPS) that steer the energy towards fixed, orthogonal directions. That is, only a finite number of steerable beam directions for the main lobe may be possible using a Butler matrix architecture. Furthermore, the PPS beams may have deterministic beamwidths, side lobe levels, and/or other beam properties (e.g., which may be dependent only on antenna dimensions). The Butler matrix architecture may allow for reduced flexibility/adaptability of beamforming, as compared to the vector sum modulator architecture since the beam properties cannot be adapted to channel conditions. However, the Butler matrix architecture may conserve space/area on a semiconductor chip, and may reduce power consumption and generation of thermal energy, as compared to the vector sum modulator architecture, especially as the carrier frequency increases. 
     In some examples, a UE (or other network device) may perform beamforming using other beamforming architectures (e.g., a Rotman or a Luneberg lens array) with different levels of customizability. 
       FIG.  3 A  is a diagram illustrating an example of a Butler matrix  300 , in accordance with the present disclosure. A Butler matrix architecture may conserve space/area on a semiconductor chip as well as power during beamforming operations of a network device (e.g., a UE, a base station, an IRS node, a repeater node, or an IAB node). For example, a network device may use a Butler matrix architecture to communicate via a set of beams (e.g., a static set of beams) over millimeter wave bands and/or sub-terahertz frequencies. 
     The Butler matrix  300  includes a set of input/output ports  305  that can receive signals on which the Butler matrix  300  operates and/or provide signals to another component (e.g., an antenna or a frontend component, among other examples) after the Butler matrix  300  operates on the signals. In a three stage Butler matrix architecture with 8 input/output ports, as shown in  FIG.  3 A , the set of input/output ports  305  are connected to a set of hybrid couplers  310 , a set of phase shifters  315 , a set of hybrid couplers  320 , a set of phase shifters  325 , a set of hybrid couplers  330 , and/or a set of input/output ports  335 . The sets of hybrid couplers  310 ,  320 ,  330  may provide connections that change an order of signals within the Butler matrix, such that an order (e.g., from top to bottom) at the set of input/output ports  305  is different from an order (e.g., from left to right) at the set of input/output ports  335 . The sets of phase shifters  315 ,  325  may change phase shifts of signals within the Butler matrix, with each phase shifter having a fixed phase shift. For example, the set of phase shifters  315  may include phase shifters that shift phases by −67.5 degrees and phase shifters that shift phases by −22.5 degrees. The set of phase shifters  325  may include phase shifters that shift phases by −45 degrees. 
     In this way, the Butler matrix  300  may use circuitry to form a static set of beams through which a network device may communicate. The Butler matrix  300  has a first number of input ports (e.g., 2, 4, 8, etc.) where a signal is applied (e.g., received) and a second number of output ports (e.g., 2, 4, 8, etc.). The input ports may be coupled to antenna elements, or the output ports may be coupled to the antenna elements. The Butler matrix  300  may be configured to operate in both directions (e.g., a set of ports functions as input ports in a receive direction and as output ports in a transmit direction). For example, the set of input/output ports  335  may be coupled to a respective set of antenna elements. In the transmit direction, the set of input/output ports  305  may be the input ports, and the set of input/output ports  335  may be the output ports. In this case, one or more signals (e.g., signals A, B, C, D, E, F, G, and/or H) may be input to the set of input/output ports  305 . The one or more signals may be processed by the sets of hybrid couplers  310 ,  320 ,  330  and the sets of phase shifters  315 ,  325  and output by the set of input/output ports  335  to the respective set of antenna elements. In the receive direction, the set of input/output ports  335  may be the input ports, and the set of input/output ports may be the output ports. In this case, signals received by the antenna elements may be input to the set of input/output ports  335 , processed by the sets of hybrid couplers  310 ,  320 ,  330  and the sets of phase shifters  315 ,  325  and output by the set of input/output ports  305  (e.g., to a frontend component of the network device). 
     The Butler matrix may include (N/2)*log 2 (N) hybrid couplers and (N/2)*(log 2 (N)−1) fixed value phase shifters, where N is a number of input ports. In some examples, N may be a power of (e.g., 2, 4, 8, etc.). As shown in  FIG.  3   , the Butler matrix may be configured with 8 input ports, such that N=8. In this case, the Butler matrix includes 12 hybrid couplers and 8 fixed value phase shifters. 
     The Butler matrix supports communication over a number of beams that may be equal to a number of input/output ports of the Butler matrix. The beams may be fixed, orthogonal, and simultaneously steerable. In this way, the Butler matrix may conserve power and semiconductor chip space when compared to beamforming hardware that includes a set of phase shifters that may be configured to apply variable phase shifts (e.g., as in a vector sum modulator architecture) and may be configurable to communicate using an increased number of beams. The area/space savings comes from the capability of a Butler matrix to simultaneously steer multiple beams with the same set of circuit components, which in the case of a vector sum modulator architecture requires the replication of hardware components for each steerable beam. However, the base station and the UE may not be synchronized regarding a type of beamforming configuration that is supported by the UE. For example, if the UE supports a relatively small set of fixed beams for communicating with a base station, and the base station expects the UE to support a relatively large set of beams, the base station may communicate using a narrow beam, and the UE may fail to receive communications from the base station. This may cause the UE and/or the base station to consume power, communication, latency, computing, and/or network resources to detect and/or correct communication errors. 
     As indicated above,  FIG.  3 A  is provided as an example. Other examples may differ from what is described with regard to  FIG.  3 A . 
       FIG.  3 B  is a diagram illustrating an example  350  of beams formed using the Butler matrix  300  of  FIG.  3 A , in accordance with the present disclosure. As shown in  FIG.  3 B , the Butler matrix forms a static set of beams ( 1 L,  2 L,  3 L,  4 L,  1 R,  2 R,  3 R, and  4 R) through which a network device may communicate. In the transmit direction, each input port in the set of input/output ports  305  corresponds to a respective beam in the set of beams. A signal (e.g., A, B, C, D, E, F, G or H) input to an input port is processed by the sets of hybrid couplers  310 ,  320 ,  330  and the sets of phase shifters  315 ,  325 , and is thus output from the output ports in the set of input/output ports  335  to the respective antenna elements at different phase offsets, resulting in transmission in a beam direction associated with a respective beam in the set of beams. For example, beam  1 L may be formed from signal A, beam  2 L may be formed from signal E, beam  3 L may be formed from signal C, beam  4 L may be formed from signal G, beam  1 R may be formed from signal H, beam  2 R may be formed from signal D, beam  3 R may be formed from signal F, and beam  4 R may be formed from signal B. The beams ( 1 L,  2 L,  3 L,  4 L,  1 R,  2 R,  3 R, and  4 R) may be fixed, orthogonal, and simultaneously steerable. 
     As indicated above,  FIG.  3 B  is provided as an example. Other examples may differ from what is described with respect to  FIG.  3 B . 
     As described above, UEs and/or other network devices may use different beamforming architectures. In some cases, such as if a single antenna module or radio frequency integrated circuit (RFIC) is selected for a UE, which beamforming architecture is used at the UE may depend on antenna array size, carrier frequency, the type of superheterodyne architecture used including the intermediate carrier frequency, a need for flexibility in beamforming capabilities (e.g., based at least in part on use cases supported by the UE, applications that are optimized for by the UE, etc.), chip area needed for the beamforming architecture, and/or power consumption and/or thermal energy generation tradeoffs, among other examples. In some examples, UEs (and/or other network devices) with large antenna arrays may utilize Butler matrix architectures to conserve space on a semiconductor chip and reduce power consumption and thermal energy, as compared to vector sum modulator architectures. 
     In some aspects, a UE (or other network device) may utilize a beamforming architecture that includes an antenna array arranged in a number of blocks of antenna elements, and each block of antenna elements may be associated with a respective Butler matrix. In this way, the UE (or other network device) may reduce space on a semiconductor chip, power consumption, and thermal energy, as compared to a vector sum modulator architecture, with increased beamforming flexibility, as compared to single Butler matrix architecture. However, different UEs may use different beamforming architectures with different beamforming capabilities, and the base station and the UE may not be synchronized regarding the capability of the beamforming architecture of the UE. For example, if the UE supports a relatively small set of fixed beams for communicating with the base station, and the base station expects the UE to support a relatively large set of beams, the base station may communicate using a narrow beam, and the UE may fail to receive communications from the base station. This may cause the UE and/or the base station to consume power, communication, latency, computing, and/or network resources to detect and/or correct communication errors. 
     Some techniques and apparatuses described herein enable a network device (e.g., a UE or other network device) to transmit, to a base station, an indication of a capability of the beamforming architecture of the network device. The network device and the base station may communicate based at least in part on the capability of the beamforming architecture of the network device. For example, the base station may determine a beamwidth, a transmit power, and/or one or more other properties for communications (e.g., downlink and/or uplink communications) between the base station and the network device based at least in part on the indication of the capability of the beamforming architecture received from the network device. As a result, communication errors between the base station and the network device may be reduced, which may decrease power consumption, communication latency, and/or consumption of computing and/or network resources associated with detecting and correcting communication errors. Furthermore, such signaling of the capability of the beamforming architecture may allow for increased use of Butler matrix based beamforming architectures, which may result in reduced space on a semi-conductor chip, reduced power consumption, and reduced thermal energy generation, particularly for network devices with large antenna arrays. 
       FIG.  4    is a diagram illustrating examples  400  and  410  associated with beamforming architecture configurations for a network device, in accordance with the present disclosure. In some aspects, the network device may be a UE. In some aspects, the network device may be an IRS node, a repeater node, or an IAB node. 
     In some aspects, a beamforming architecture of the network device may include an antenna array or panel that includes a plurality of antenna elements, and the antenna array or panel may be arranged into a plurality of blocks of antenna elements, with each block of the plurality of blocks being associated with a respective Butler matrix beamforming architecture. The Butler matrix beamforming architectures may be implemented using radio frequency (RF) circuitry, such as the Butler matrix architecture shown in  FIG.  3 A . In some aspects, a 2 N ×2 M  planar array of antenna elements may include a plurality of blocks of 2 P  antenna elements, where each block is controlled by a respective Butler matrix beamforming architecture that produces fixed sets of beam weights. The fixed sets of beam weights produced by each Butler matrix beamforming architecture may be associated with a respective set of static beams that can be formed by the set of 2 P  antenna elements controlled by that Butler matrix beamforming architecture. In the case in which each block includes 2 P  antenna elements, the 2 N ×2 M  planar array may include 2 N+M-P  blocks of antenna elements. For example, an 8×4 array of antenna elements (e.g., N=3, M=2) designed with a Butler matrix block size of 8 (e.g., P=3) may include 4 blocks of antenna elements (e.g., 4 blocks, each having 8 antenna elements, with each block of 8 antenna elements being controlled by a respective Butler matrix). 
     In some aspects, for an antenna array or panel having a certain number of antenna elements, there may be multiple arrangements of the antenna elements into the plurality of blocks that are controlled by respective Butler matrix beamforming architectures. As shown in  FIG.  4   , example  400  shows an arrangement of the antenna elements in an 8×4 array into a plurality of blocks according to a first configuration, and example  410  shows an arrangement of the antenna elements in an 8×4 array into a plurality of blocks according to a second configuration. The first and second configurations may result in different constraints on the type of beam weights possible and the realizable gains possible in different beam directions. In some aspects, other configurations may be possible as well. 
     As shown in example  400 , in the first configuration, the 8×4 array of antenna elements is arranged into 4 blocks  405   a ,  405   b ,  405   c , and  405   d , with each block  405   a ,  405   b ,  405   c , and  405   d  including 8 antenna elements arranged in a 4×2 configuration. Each block  405   a ,  405   b ,  405   c , and  405   d  may be controlled by a respective Butler matrix beamforming architecture that produces respective fixed sets of beam weights. For example, using the respective Butler matrix beamforming architecture associated with each 4×2 block  405   a ,  405   b ,  405   c , and  405   d , the network device may be capable of forming a respective static/fixed set of beams with the antenna elements in each block  405   a ,  405   b ,  405   c , and  405   d.    
     As shown in example  410 , in the second configuration, the 8×4 array of antenna elements are arranged into 4 blocks  415   a ,  415   b ,  415   c , and  415   d , with each block  415   a ,  415   b ,  415   c , and  415   d  including 8 antenna elements arranged in a 2×4 configuration. Each block  415   a ,  415   b ,  415   c , and  415   d  may be controlled by a respective Butler matrix beamforming architecture that produces respective fixed sets of beam weights. For example, using the respective Butler matrix beamforming architecture associated with each 2×4 block  415   a ,  415   b ,  415   c , and  415   d , the network device may be capable of forming a respective static/fixed set of beams with the antenna elements in each block  415   a ,  415   b ,  415   c , and  415   d.    
     As indicated above,  FIG.  4    is provided as an example. Other examples may differ from what is described with respect to  FIG.  4   . 
       FIG.  5    is a diagram illustrating an example  500  associated with a beamforming architecture configuration for a network device, in accordance with the present disclosure. In some aspects, the network device may be a UE. In some aspects, the network device may be an IRS node, a repeater node, or an IAB node. 
     As described above in connection with  FIG.  4   , the beamforming architecture of the network device may include an antenna array or panel that includes a plurality of antenna elements, and the antenna array or panel may be arranged into a plurality of blocks of antenna elements, with each block of the plurality of blocks being associated with a respective Butler matrix beamforming architecture. In some aspects, the beamforming architecture of the network device may be configured to apply phase offset quantization across different blocks of the plurality of blocks of antenna elements. In this case, a phase quantization level may be applied across the antenna elements in a first block of antenna elements and a second block of antenna elements. The phase quantization level may be a phase offset between the fixed sets of beams weights associated with the first block of antenna elements and the fixed set of beam weights associated with the second block of antenna elements. In some aspects, a different phase quantization level may be applied between a first block of antenna elements, and each other block of antenna elements in the antenna array or panel. 
     As shown in  FIG.  5   , example  500  shows an example of phase offset quantization for the first configuration of an 8×4 array of antenna elements shown in example  400  of  FIG.  4   . As shown in  FIG.  5   , a first phase quantization level α may be applied between a first block  405   a  and a second block  405   b . The antenna elements in the first block  405   a , as controlled by the respective Butler matrix beamforming architecture associated with the first block  405   a , may produce fixed sets of beam weights (e.g., a respective fixed set of beam weights for each of the 8 possible beams that can be formed by the antenna elements in the first block  405   a ). The first phase quantization level a may indicate a phase offset that is applied, across all of the antenna elements in the first block  405   a  and the second block  405   b , such that the fixed sets of beam weights for the antenna elements in the second block  405   b  are offset by a from the fixed sets of beam weights for corresponding antenna elements in the first block  405   a . For example, first phase quantization level α may be applied to respective beam weights of W f1 , W f2 , W f3 , W f4 , W f5 , W f6 , W f7 , and W f8 , for the 8 antenna elements in the first block  405   a , to generate respective beam weights of α+W f1 , α+W f2 , α+W f3 , α+W f4 , α+W f5 , α+W f6 , α+W f7 , and α+W f8  for the 8 antenna elements in the second block  405   b.    
     As further shown in  FIG.  5   , a second phase quantization level β may be applied between the first block  405   a  and a third block  405   c . The second phase quantization level β may indicate a phase offset that is applied, across all of the antenna elements in the first block  405   a  and the third block  405   c , such that the fixed sets of beam weights for the antenna elements in the third block  405   c  are offset by β from the fixed sets of beam weights for corresponding antenna elements in the first block  405   a . For example, second phase quantization level β may be applied to the respective beam weights of W f1 , W f2 , W f3 , W f4 , W f5 , W f6 , W f7 , and W f8 , for the 8 antenna elements in the first block  405   a , to generate respective beam weights of β+W f1 , β+W f2 , β+W f3 , β+W f4 , β+W f5 , β+W f6 , β+W f7 , and β+W f8  for the 8 antenna elements in the third block  405 . 
     As further shown in  FIG.  5   , a third phase quantization level γ may be applied between the first block  405   a  and a fourth block  405   d . The third phase quantization level β may indicate a phase offset that is applied, across all of the antenna elements in the first block  405   a  and the fourth block  405   d , such that the fixed sets of beam weights for the antenna elements in the fourth block  405   d  are offset by γ from the fixed sets of beam weights for corresponding antenna elements in the first block  405   a . For example, third phase quantization level γ may be applied to the respective beam weights of W f1 , W f2 , W f3 , W f4 , W f5 , W f6 , W f7 , and W f8 , for the 8 antenna elements in the first block  405   a , to generate respective beam weights of γ+W f1 , γ+W f2 , γ+W f3 , γ+W f4 , γ+W f5 , γ+W f6 , γ+W f7 , and γ+W f8  for the 8 antenna elements in the fourth block  405   d.

     The foregoing disclosure provides illustration and description but is not intended to be exhaustive or to limit the aspects to the precise forms disclosed. Modifications and variations may be made in light of the above disclosure or may be acquired from practice of the aspects. 
     As used herein, the term “component” is intended to be broadly construed as hardware and/or a combination of hardware and software. “Software” shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, and/or functions, among other examples, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. As used herein, a “processor” is implemented in hardware and/or a combination of hardware and software. It will be apparent that systems and/or methods described herein may be implemented in different forms of hardware and/or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems and/or methods is not limiting of the aspects. Thus, the operation and behavior of the systems and/or methods are described herein without reference to specific software code, since those skilled in the art will understand that software and hardware can be designed to implement the systems and/or methods based, at least in part, on the description herein. 
     As used herein, “satisfying a threshold” may, depending on the context, refer to a value being greater than the threshold, greater than or equal to the threshold, less than the threshold, less than or equal to the threshold, equal to the threshold, not equal to the threshold, or the like. 
     Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of various aspects. Many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. The disclosure of various aspects includes each dependent claim in combination with every other claim in the claim set. As used herein, a phrase referring to “at least one of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover a, b, c, a+b, a+c, b+c, and a+b+c, as well as any combination with multiples of the same element (e.g., a+a, a+a+a, a+a+b, a+a+c, a+b+b, a+c+c, b+b, b+b+b, b+b+c, c+c, and c+c+c, or any other ordering of a, b, and c). 
     No element, act, or instruction used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items and may be used interchangeably with “one or more.” Further, as used herein, the article “the” is intended to include one or more items referenced in connection with the article “the” and may be used interchangeably with “the one or more.” Furthermore, as used herein, the terms “set” and “group” are intended to include one or more items and may be used interchangeably with “one or more.” Where only one item is intended, the phrase “only one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” or the like are intended to be open-ended terms that do not limit an element that they modify (e.g., an element “having” A may also have B). Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise. Also, as used herein, the term “or” is intended to be inclusive when used in a series and may be used interchangeably with “and/or,” unless explicitly stated otherwise (e.g., if used in combination with “either” or “only one of”).
