Description

[0001] Cross Reference to Related Applications

[0002] This patent application claims priority to U.S. Non-Provisional Patent Application No. 18 / 186,546, filed March 30, 2023, entitled “HIGH RANK MULTIPLE INPUT MULTIPLE OUTPUT FOR MULTI-BAND ANTENNA MODULE WIRELESS COMMUNICATION DEVICES,” which application is expressly incorporated by reference herein in its entirety. TECHNICAL FIELD

[0003] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for high rank multiple input multiple output for multi-band antenna module wireless communication devices. BACKGROUND

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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 (3 GPP).

[0005] A wireless network can include one or more network nodes that support communications for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE can communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL”) refers to communications from network nodes to UEs, and “uplink” (or “UL”) refers to communications from UEs to network nodes. Some wireless networks can support device-to-device communications, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, among others).

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols facilitating communication between UEs from different technologies. New Radio (NR), which can be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 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, 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, and support 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. SUMMARY

[0029] In a wireless network, network nodes and user equipment (UEs) can communicate via one or more beams. A “beam” can refer to a wireless communication signal that is shaped via beamforming and transmitted in a particular / set of spatial directions rather than being transmitted omnidirectionally.

[0030] Millimeter wave (mmWave) beamforming can cover a set of frequencies such as in FR2. Examples include operating frequency bands n257, n258, n259, n261, and / or n260, among others. As the frequency bands used in wireless networks continue to evolve, beamforming support for additional frequencies such as n262 and n263, among others, is also needed. However, these additional frequencies can be significantly different from the currently supported frequencies, which can make it difficult to add additional antenna modules to a UE to support the additional frequencies.

[0031] ​In some aspects described herein, a UE can include a (multi-band) antenna module that covers one or more multiple frequency bands. A “multi-band antenna module” can refer to an antenna module that includes a first subset of antennas (or antenna elements) configured to support wireless communications on a first frequency band (e.g., a FR2 frequency band) and a second subset of antennas (or antenna elements) configured to support wireless communications on a second frequency band (e.g., a FR3 frequency band or a FR4 frequency band).

[0032] Inclusion of a multi-band antenna module in a UE provides the UE with the ability to support high rank multiple-input multiple-output (MIMO) communications on two or more frequency bands. “High rank MIMO communications” (also referred to as higher rank MIMO communications) refers to wireless communications that use more than two polarization layers (e.g., 3 layers, 4 layers, or a greater number of layers) across two or more frequency bands. A “layer” can refer to a spatial or polarization layer of wireless communications transmitted (and / or received) on one or more beams.

[0033] The two or more frequency bands can have (or can share) a common intermediate frequency. An “intermediate frequency” can refer to a frequency between a radio frequency (RF) and a baseband frequency of a UE. Rather than converting signals directly between the RF frequency and the baseband frequency, a UE can convert (e.g., downconvert) the RF frequency to the intermediate frequency, and then convert (e.g., downconvert) from the intermediate frequency to the baseband frequency using a superheterodyne architecture. The UE can perform these operations in the reverse order, i.e., convert (e.g., upconvert) from the baseband frequency to the RF frequency using the intermediate frequency. This enables the UE to convert communications via the two or more frequency bands between RF signals (e.g., analog signals transmitted and / or received via the two or more frequency bands) and baseband signals (e.g., signals processed by a modem or baseband processor of the UE) using the same (or common) intermediate frequency (rather than a different intermediate frequency for each of the two or more frequency bands).

[0034] To support configuring and / or scheduling high rank MIMO communications for a UE, the UE can provide signaling to a network node, where the signaling can indicate a capability of the UE to support high rank MIMO communications (e.g., on two or more frequency bands having a common intermediate frequency). The signaling from the UE enables the network node to know the capability of the UE to support high rank MIMO communications, which enables the network node to configure and / or schedule high rank MIMO communications for the UE.

[0035] In some cases, lower rank transmissions may be performed in the same (single) direction (e.g., rank 1 transmissions in non-polarization-based transmissions on one layer, rank 2 transmissions in polarization-based transmissions on two layers). However, as described herein, the UE and the network node may be able to perform high rank MIMO communication in approximately the same direction on two or more frequency bands (e.g., having a common intermediate frequency). In these aspects, signaling provided by the UE to the network node indicating the UE's ability to support high rank MIMO communication enables the UE and the network node to perform high rank MIMO communication in a selected direction.

[0036] In some cases, high-rank transmission may be indicated by a higher value of a rank indicator (RI), where for codebook-based beamforming, the RI is typically matched to an appropriate precoder matrix from the codebook (or derived for non-codebook-based beamforming). However, the RI is typically a measure of the digital / baseband precoding rank. As described herein, signaling provided by a UE to a network node indicating the UE's ability to support high-rank MIMO communications may enable the UE to indicate one or more hybrid beamforming beam weight sets to be supported for high-rank MIMO communications. Thus, in various aspects described herein, signaling from the UE enables the use of RF / analog precoding (e.g., through a combination of over-the-air phase shifting of antenna elements and / or automatic gain control (AGC)) instead of (and / or in addition to) digital precoding for high-rank MIMO communications.

[0037] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It will be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functionality, or structure and functionality in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present claims.

[0038] Several aspects of telecommunication systems will now be presented with reference to various apparatus and techniques. These apparatus and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular applications and design constraints imposed on the overall system.

[0039] While aspects can 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).

[0040] Figure 1 FIG. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 can be or can 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 can include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one UE 120, or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. A network node 110 is a network node with which a UE 120 communicates. As illustrated, a network node 110 can include one or more network nodes. For example, a network node 110 can be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, a network node 110 can be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed across two or more nodes, such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs).

[0041] In some examples, the network nodes 110 are or include network nodes that communicate with UEs 120 via radio access links, such as RUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via a front-haul link or a mid-haul link, such as DUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via a mid-haul link or with a core network via a backhaul link, such as CUs. In some examples, a network node 110, such as an aggregated network node 110 or a disaggregated network node 110, can include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network nodes 110 can include, for example, an NR base station, an LTE base station, a NodeB, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmission reception point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, network equipment, a RAN node, or combinations thereof. In some examples, the network nodes 110 can interconnect with one another or to one or more other network nodes in the wireless network 100 using any suitable transport network, such as a direct physical connection, an air interface, or virtual network. In some examples, the network nodes 110 can interconnect with one another or to one or more other network nodes in the wireless network 100 using any suitable transport network, such as a direct physical connection, an air interface, or virtual network.

[0042] In some examples, a network node 110 can provide communication coverage for a particular geographic area. In Third Generation Partnership Project (3GPP) terminology, the term "cell" can refer to a coverage area of a network node 110 and / or a subsystem of a network node 110 that serves the coverage area, depending on the context in which the term is used. The network nodes 110 can be a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., several kilometers in radius) and can allow unrestricted access by UEs 120 with service subscriptions. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UEs 120 with service subscriptions. A femto cell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UEs 120 that are associated with an access subscription. Figure 1In the illustrated example, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, cells can not necessarily be stationary, and the geographic area of a cell can move according to the location of a mobile network node 110 (e.g., a mobile network node).

[0043] In some aspects, the term “base station” or “network node” can refer to an aggregated base station, disaggregated base station, integrated access and backhaul (IAB) node, relay node, or one or more components thereof. For example, in some aspects, a “base station” or “network node” can refer to a CU, DU, RU, near real-time (near-RT) RAN intelligent controller (RIC), or a non-RT RIC, or a combination thereof. In some aspects, the term “base station” or “network node” can refer to one device configured to perform one or more functions, such as those described herein in connection with network node 110. In some aspects, the term “base station” or “network node” can refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which can be located in the same geographic location or different geographic locations) can be configured to perform at least a portion of a function, or to repeat at least a portion of the function, and the term “base station” or “network node” can refer to any one or more of these different devices. In some aspects, the term “base station” or “network node” can refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term “base station” or “network node” can refer to one of a base station function as opposed to another base station function. In this way, a single device can include more than one base station.

[0044] Wireless network 100 can include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., a network node 110 or a UE 120) and send a transmission of the data to a downstream node (e.g., a UE 120 or a network node 110). A relay station can be a UE 120 that can relay transmissions for other UEs 120. In Figure 1 In the example shown in FIG. 1, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d in order to facilitate communication between network node 110a and UE 120d. A network node 110 that relays communications can be referred to as a relay station, a relay base station, a relay network node, a relay node, or the like.

[0045] Wireless network 100 can be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, and / or the like. These different types of network nodes 110 can have different transmit power levels, different coverage areas, and / or different impacts on interference. For example, macro network nodes can have a high transmit power level (e.g., 5 to 40 watts), while pico network nodes, femto network nodes, and relay network nodes can have relatively lower transmit power levels (e.g., 0.1 to 2 watts).

[0046] A network controller 130 can couple to or communicate with a set of network nodes 110 and can provide coordination and control for the network nodes 110. The network controller 130 can communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 can also communicate with one another directly, via wireless backhaul communication links, or indirectly via the network controller 130, via wireless backhaul communication links, or via a wired backhaul communication link. In some aspects, the network controller 130 can be a CU or a core network device, or can include a CU or a core network device.

[0047] The UEs 120 can be dispersed throughout the wireless network 100, and each UE 120 can be stationary or mobile. A UE 120 can include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. A UE 120 can 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, a UE function of a network node, and / or any other suitable device that is configured to communicate via a wireless or wired medium.

[0048] Some UEs 120 can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC or eMTC UEs can include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a network node, another device (e.g., remote device), or some other entity. A

[0049] In general, any number of wireless networks 100 can be deployed in a given geographic area. Each wireless network 100 can support a particular RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology, an air interface, and / or the like. Frequencies can be referred to as carriers, frequency channels, and / or the like. In some cases, a single frequency can be used for multiple RATs. In some cases, a

[0050] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with one another). For example, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110. In some examples, one or more of these direct communications can use a

[0051] Devices of wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various classes, bands, channels, and so on, according to frequency or wavelength. For example, devices of wireless network 100 can communicate using one or more of the operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 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 (interchangeably) referred to as a “millimeter wave” band in documents and articles, despite the fact that it falls into a larger frequency band identified as Extremely High Frequency (EHF) by the International Telecommunications Union (ITU) (30 GHz to 300 GHz).

[0052] 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 (37 GHz to 48.2 GHz). Bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the characteristics of FR1 and / or FR2 to mid-band frequencies. Moreover, even higher bands are currently under exploration to extend 5G NR operation beyond 50 GHz. For example, three higher operating bands have been identified as frequency range designations FR4-a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher bands falls within the EHF band.

[0053] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “Sub-6 GHz” or the like is used herein to generically refer to frequencies that can be below 6 GHz, can be within FR1, or can include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like is used herein to generically refer to frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a, or FR4-1, and / or FR5, or can be within the EHF band. It is contemplated that frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0054] As Figure 1Further shown, network node 110 can communicate with UE 120 via one or more network node (NN) beams 140. UE 120 can communicate with network node 110 via one or more UE beams 150. The one or more NN beams 140 can be wide NN beams, narrow NN beams, or a combination thereof. The one or more UE beams 150 can be wide UE beams, narrow UE beams, or a combination thereof.

[0055] A “wide beam” refers to a wireless communication beam that has not been refined and / or that is associated with a smaller beamforming gain. A wide beam can also be referred to as an unrefined beam. A “narrow beam” refers to a wireless communication beam that has a high degree of directionality and that has a high beamforming gain. A narrow beam can also be referred to as a refined beam. While a wide beam can generally provide a greater coverage, a narrow beam can provide a higher throughput and lower latency, among other things. A wide beam can spread a network node’s transmit power over a larger geographic coverage area relative to a narrow beam. A narrow beam can concentrate a network node’s transmit power in a relatively small geographic area, which enables a greater amount of transmit power (and thus, greater throughput) to be directed toward a particular UE (e.g., relative to a wide beam). Because a narrow beam has a smaller geographic or spatial coverage relative to a wide beam, a narrow beam can enable a greater number of beams to be used, which can provide additional spatial diversity across different beams relative to a wide beam.

[0056] In some aspects, UE 120 can include a communication manager 160. As described in more detail elsewhere herein, the communication manager 160 can transmit, to a network node via a transceiver, an indication of a capability of the UE to support high rank MIMO communications over two or more frequency bands having a common intermediate frequency, where the capability to support the high rank MIMO communications includes a capability to support MIMO communications in substantially a same direction and over more than two layers; and perform, via the transceiver, the high rank MIMO communications with the network node in the substantially same direction over the two or more frequency bands. Additionally, or alternatively, the communication manager 160 can perform one or more other operations described herein.

[0057] In some aspects, network node 110 can include a communication manager 170. As described in more detail elsewhere herein, the communication manager 170 can receive, from a UE, an indication of a capability of the UE to support high rank MIMO communications over two or more frequency bands having a common intermediate frequency, where the capability to support the high rank MIMO communications includes a capability to support MIMO communications in substantially a same direction and over more than two layers; in some cases, the UE can perform the high rank MIMO communications in the substantially same direction over the two or more frequency bands. Additionally, or alternatively, the communication manager 170 can perform one or more other operations described herein.

[0058] As indicated above, Figure 1 are provided by way of example. Other examples can differ from those described Figure 1 without departing from the description of the examples as described in relation to

[0059] Figure 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in the wireless network 100, in accordance with the present disclosure. The network node 110 can be equipped with a set of antennas 234a through 234t, such as T antennas (T> 1). The UE 120 can be equipped with a set of antennas 252a through 252r, such as R antennas (R > 1). The network node 110 of example 200 includes one or more radio front end components, such as antennas 234 and modem 232. In some examples, the network node 110 can include an interface, communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 can not include radio frequency components that facilitate direct communication with UEs 120, such as one or more CUs or one or more DUs.

[0060] At the network node 110, a transmit processor 220 can receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 can 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 the UE 120. The network node 110 can process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCSs selected for the UE 120 and can provide data symbols for the UE 120. The transmit processor 220 can 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 can 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 can perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and can 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 232a through 232t. Each output symbol stream can be provided to a modulator component (shown as MOD) of a modem 232 using a respective modulator component. Each modem 232 can process a respective output symbol stream (e.g., for OFDM) using a respective modulator component to obtain an output sample stream. Each modem 232 can further process the output sample stream (e.g., convert to analog, amplify, filter, and / or upconvert) using a respective modulator component to obtain a downlink signal. The modems 232a through 232t can 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 234a through 234t.

[0061] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) can receive the downlink signals from network nodes 110 and / or other network nodes 110 and can provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 can 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 can use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain received symbols from modems 254, can perform MIMO detection on the received symbols if applicable, and can provide detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, can provide decoded data for UE 120 to a data sink 260, and can provide decoded control information and system information to a controller / processor 280. The term “controller / processor” can refer to one or more controllers, one or more processors, or combinations thereof. A channel processor can determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or CQI parameters, among other examples. In some examples, one or more components of UE 120 can be included in a housing 284.

[0062] Network controller 130 can include communication unit 294, controller / processor 290, and memory 292. Network controller 130 can include, for example, one or more devices in a core network. Network controller 130 can communicate with network node 110 via communication unit 294.

[0063] One or more antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) can include or be included in 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, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements (within a single housing or multiple housings), a set of co-planar antenna elements, a set of non-co-planar antenna elements, and / or one or more antenna elements coupled to one or more transmit and / or receive components (such as, for example, one or more components in a transceiver 232 and / or a modem 254). Figure 2 ​

[0064] On the uplink, at UE 120, a transmit processor 264 can receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280. Transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from transmit processor 264 can be precoded by a TX MIMO processor 266 if applicable, further processed by modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, modems 254 of UE 120 can include modulators and demodulators. In some examples, UE 120 includes a transceiver. The transceiver can include any combination of antenna 252, modems 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (for example, with reference to Figures 4A-10 ) and / or with respect to other processes described herein.

[0065] At network node 110, the uplink signals from UE 120 and / or other UEs can be received by antennas 234, processed by modems 232 (e.g., demodulator components (shown as DEMOD) of modems 232), detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Network node 110 can include communication unit 244 and can communicate with network controller 130 via communication unit 244. Network node 110 can include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, modems 232 of network node 110 can include modulators and demodulators. In some examples, network node 110 includes a transceiver. The transceiver can include any combination of antenna 234, modems 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (for example, with reference to Figures 4A-10 ) and / or with respect to other processes described herein.

[0066] Controller / processor 240 of network node 110, controller / processor 280 of UE 120, and / orFigure 2 Any other components in the may perform one or more techniques associated with high-rank multiple-input multiple-output for multi-band antenna module wireless communication devices, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the may perform or direct e.g. Figure 7 The process of 700 Figure 8 800 and / or other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or 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 compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 7 The process of 700 Figure 8 The process 800 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0067] In some aspects, the UE 120 includes components for sending an indication to a network node of an ability to support high-rank MIMO communications on two or more frequency bands having a common intermediate frequency (e.g., using the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the modem 254, the antenna 252, the memory 282, etc.), wherein the ability to support the high-rank MIMO communications includes the ability to support MIMO communications in approximately the same direction and on more than two layers; and / or components for performing the high-rank MIMO communications with the network node on the two or more frequency bands in the approximately same direction (e.g., using the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the modem 254, the antenna 252, the MIMO detector 256, the receive processor 258, the memory 282, etc.). Means for UE 120 to perform the operations described herein may include, for example, one or more of the communications manager 160, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0068] In some aspects, network node 110 includes means for receiving, from a UE 120, an indication of a capability of the UE 120 to support high rank MIMO communication on two or more frequency bands with a common intermediate frequency, where the capability to support the high rank MIMO communication includes a capability to support MIMO communication in substantially the same direction and on more than two layers, and / or means for performing, with the UE, the high rank MIMO communication in the substantially same direction on the two or more frequency bands (e.g., using transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, and / or the like). The means for the network node to perform operations described herein can include, for example, one or more of communication manager 170, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0069] Although Figure 2 The blocks in FIG. 13 are illustrated as distinct components merely for clarity. The functions described above relative to these blocks can be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described relative to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of the controller / processor.

[0070] As indicated above, the functions described with Figure 2 are provided as examples. Other examples can differ from what is described with respect to the examples Figure 2 described.

[0071] Deployment of communication systems, such as 5G NR systems, can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, network nodes, network entities, mobility elements of a network, RAN nodes, core network nodes, network elements, base stations, or network equipment of a network can be implemented in an aggregated architecture or a disaggregated architecture. For example, a base station, such as a Node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP, or a cell, and so forth, or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as a standalone base station or a monolithic base station) or a disaggregated base station. A “network entity” or “network node” can refer to a disaggregated base station or one or more units of a disaggregated base station, such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof.

[0072] An aggregated base station (e.g., an aggregated network node) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A disaggregated base station (e.g., a disaggregated network node) can be configured to utilize a protocol stack that is physically or logically distributed between two or more units, such as one or more CUs, one or more DUs, or one or more RUs. In some examples, a CU can be implemented within a network node, and one or more DUs can be co-located with the CU or, alternatively, can be geographically or virtually spread across one or more other network nodes. The DUs can be implemented to communicate with one or more RUs. Each of the CUs, DUs, and RUs can also be implemented as virtual units, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and so forth.

[0073] Base station type operations or network designs can take into account the aggregated nature of base station functionality. For example, a disaggregated base station can be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)) or a virtualized radio access network (vRAN, also referred to as a cloud radio access network (C-RAN)) to facilitate scaling of a communication system by separating base station functionality into one or more units that can be deployed individually. A disaggregated base station can include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which can enable flexibility in network design. The various units of a disaggregated base station can be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0074] Figure 3FIG2 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. Decomposed base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). CU 310 may communicate with one or more DUs 330 via corresponding midhaul links (such as via an F1 interface). Each of DUs 330 may communicate with one or more RUs 340 via corresponding fronthaul links. Each of RUs 340 may communicate with one or more UEs 120 via corresponding radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0075] Each of the units (including the CU 310, DU 330, and RU 340), as well as the near-RT RIC 325, the non-RT RIC 315, and the SMO framework 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller that provides instructions to the one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via the wired transmission medium, and a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more of the other units via the wireless transmission medium, or both.

[0076] In some aspects, the CU 310 can host one or more higher layer control functions. Such control functions can include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among other possibilities. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bi-directionally with the CU-CP units via an interface, such as an El interface. The CU 310 can be implemented to communicate with the DUs 330 as needed for network control and signal transfer.

[0077] Each DU 330 can correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 can host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers, at least in part according to a functional split, such as one defined by 3GPP. In some aspects, the one or more high PHY layers can be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, among other possibilities. In some aspects, the DU 330 can also host one or more low PHY layers, such as implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, among other possibilities. Each layer (which can also be referred to as a module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0078] Each RU 340 can implement low-layer functionality. In some deployments, the RUs 340 controlled by the DUs 330 can correspond to logical nodes that host RF processing functions or low PHY layer functions based on a functional split (e.g., a functional split defined by 3GPP), such as a low-layer functional split, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, among other examples. In such an architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RUs 340 can be controlled by the corresponding DUs 330. In some scenarios, this configuration can enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0079] The SMO framework 305 can be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface, such as an Ol interface. For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform, such as an Open Cloud (O-Cloud) platform 390, to perform network element lifecycle management, such as instantiating virtualized network elements, via a cloud computing platform interface, such as an 02 interface. Such virtualized network elements can include, but are not limited to, the CU 310, the DUs 330, the RUs 340, the non-RT RIC 315, and the near-RT RIC 325. In some implementations, the SMO framework 305 can communicate with hardware aspects of a 4G RAN, such as an Open eNB (O-eNB) 311, via an Ol interface. Additionally, in some implementations, the SMO framework 305 can directly communicate with each of the one or more RUs 340 via a respective Ol interface. The SMO framework 305 can also include the non-RT RIC 315, which is configured to support functionality of the SMO framework 305.

[0080] The non-RT RIC 315 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and update, or policy-based steering of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to, or in communication with, the near-RT RIC 325, such as via an Al interface. The near-RT RIC 325 can be configured to include logical functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions by an interface, such as via an E2 interface, that connects one or more CUs 310, one or more DUs 330, or both, and an O-eNB with the near-RT RIC 325.

[0081] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 325 and can be received at the SMO framework 305 or the non-RT RIC 315 from non-network data sources or from network functions. In some examples, the non-RT RIC 315 or the near-RT RIC 325 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions by the SMO framework 305, such as reconfiguration via an Ol interface, or via creation of RAN management policies, such as Al interface policies.

[0082] As indicated above, Figure 3 are provided as examples. Other examples can differ from what is described Figure 3 with respect to the examples described.

[0083] Figures 4A-4C is a diagram illustrating an example of high rank MIMO communication in accordance with the present disclosure. As Figures 4A-4C indicated, high rank MIMO communication can be performed between a network node 110 and a UE 120. The network node 110 and the UE 120 can be included in a wireless network, such as the wireless network 100.

[0084] As Figure 4AAs shown in example 400 in FIG, network node 110 may communicate with UE 120 via one or more NN beams 140, and UE 120 may communicate with network node 110 via one or more UE beams 150. In some aspects, more than one beam with associated rank (e.g., more than one NN beam 140, more than one UE beam 150) may be simultaneously used for high-rank MIMO to support wireless communications on more than two layers (e.g., layers 1 through 4).

[0085] In some aspects, two or more layers (e.g., spatial layers, polarization layers) are supported on each beam. For example, layers 1 and 2 may be used on a first NN beam 140 and a first UE beam 150, and layers 3 and 4 may be used on a second NN beam 140 and a second UE beam 150. In some aspects, layers 1 and 2 may be used by the network node 110 and the UE 120 for higher-rank MIMO communications on a first frequency band (e.g., an FR2 band), and layers 3 and 4 may be used by the network node 110 and the UE 120 for higher-rank MIMO communications on a second frequency band (e.g., an FR3 band, an FR4 band).

[0086] like Figure 4A As further shown, the UE 120 may include multiple multi-band antenna modules 405, such as multi-band antenna modules 405a through 405d. The multi-band antenna modules 405 may be located on one or more sides, one or more ends, and / or another location on the housing 284 of the UE 120 to achieve good spherical coverage, provide module-level diversity, and / or overcome limited reception capabilities, among other things. For example, the multi-band antenna module 405a may be located on a first side of the housing 284 of the UE 120, and the multi-band antenna module 405c may be located on a second side of the housing 284 of the UE 120, where the first and second sides are generally orthogonal sides of the housing 284 of the UE. Other examples of orthogonal sides may include a face (e.g., back) of the housing 284 of the UE 120 and a top side of the housing 284 of the UE 120, and / or a bottom side of the housing 284 of the UE 120 and a left (or right) side of the housing 284 of the UE 120, among other things.

[0087] For another example, the multi-band antenna module 405 a may be located on a first side of the housing 284 of the UE 120, and the multi-band antenna module 405 b may be located on a second side of the housing 284 of the UE 120, where the first side and the second side are opposite sides of the housing 284 of the UE. Other examples of opposite sides may include a back side of the housing 284 of the UE 120, a left side of the housing 284 of the UE 120, and / or a right side of the housing 284 of the UE 120, and / or a bottom side of the housing 284 of the UE 120 and a top side of the housing 284 of the UE 120, etc.

[0088] Each multi-band antenna module 405 can include multiple antennas 252 (or multiple antenna elements). For example, a multi-band antenna module can include a first set of antennas 252 (or antenna elements) configured for wireless communications on a first frequency band (e.g., a FR2 band), and can include a second set of antennas 252 (or antenna elements) configured for wireless communications on a second frequency band (e.g., a FR3 band, a FR4 band), and so on. A “FR2 band” refers to a frequency band within the FR2 frequency range, a “FR3 band” refers to a frequency band within the FR3 frequency range, and a “FR4 band” refers to a frequency band within the FR4 frequency range, and so on.

[0089] In some aspects, different sets of antennas 252 (or antenna elements) of the multi-band antenna modules 405 used across different frequencies can have substantially the same boresight direction, which can enable inter-band carrier aggregation (CA) and / or inter-band dual connectivity (DC) on different frequency bands.

[0090] Two or more of the multi-band antenna modules 405a-405d can be configured for high rank MIMO communications in two or more frequency bands in substantially the same direction. In other words, two or more of the multi-band antenna modules 405a-405d can be configured to transmit communications to and / or receive communications from the network node 110 in substantially the same spatial direction. For example, two or more of the multi-band antenna modules 405a-405d can be configured to transmit communications to and / or receive communications from the network node 110 within a spatial separation of less than 90 degrees. Thus, for example, a UE beam 150 via which the multi-band antenna modules 405a and 405c transmit and / or receive communications can be refined to provide coverage in substantially the same spatial direction (e.g., rather than omnidirectional coverage or coverage in different spatial directions).

[0091] As Figure 4A Further shown, two or more of the multi-band antenna modules 405a-405d can be physically spaced apart by a Rayleigh distance (d Ray ), which refers to a threshold distance (e.g., a minimum separation distance) between the two or more of the multi-band antenna modules 405a-405d such that the two or more of the multi-band antenna modules 405a-405d appear uncorrelated to the network node 110. If the distance between the multi-band antenna modules is less than the Rayleigh distance, the correlation can increase proportionally. However, as long as the correlation coefficient satisfies a threshold, a spectral efficiency gain can be achieved.

[0092] The Rayleigh distance (d Ray ) for two or more of the multi-band antenna modules 405a-405d can be determined as:

[0093]

[0094] where λ is the wavelength of propagation for a frequency band used for wireless communication between the network node 110 and the UE 120, R is the separation distance between the antenna modules of the UE 120 and the antenna modules of the network node 110, and N is the number of antenna elements of the network node 110. The above equation can be used in a similar manner to determine the spacing between the antenna modules of the network node 110 to achieve uncorrelation at the UE 120.

[0095] As the frequency used for wireless communication between the network node 110 and the UE 120 increases (which is related to λ in the above Rayleigh distance equation), the inter-antenna separation distance for achieving uncorrelation decreases. Thus, uncorrelation can be more easily achieved for higher frequencies in FR3, FR4, and higher frequency ranges, particularly in UEs and other small form factor wireless communication devices. For example, for a 6 GHz frequency, the Rayleigh distance (d Ray ) can be approximately 1.1 meters for N = 4 and R = 100 meters; for a 30 GHz frequency, the Rayleigh distance (d Ray ) can be approximately 0.5 meters for N = 4 and R = 100 meters; and for a 120 GHz frequency, the Rayleigh distance (d Ray ) can be approximately 0.25 meters for N = 4 and R = 100 meters. At 120 GHz, this distance becomes 0.0625 m or 62.5 mm for N = 64.

[0096] Figure 4B An example 410 is illustrated in which one or more of the multiband antenna modules of the UE 120 wrap around an edge or corner of the UE 120. For example, the multiband antenna module 405a can wrap around a corner of the UE 120 such that the multiband antenna module 405a is located on a left side of the housing 284 of the UE 120 and on a bottom side of the housing 284 of the UE 120. As another example, the multiband antenna module 405b can wrap around a corner of the UE 120 such that the multiband antenna module 405b is located on a right side of the housing 284 of the UE 120 and on a top side of the housing 284 of the UE 120.

[0097] Figure 4CExample 420 is illustrated, in which one or more of the multi-band antenna modules of the UE 120 wrap around an edge or corner of the UE 120. For example, the multi-band antenna module 405a can wrap around an edge of the UE 120 such that the multi-band antenna module 405a is located on a right side of the housing 284 of the UE 120 and on a front of the housing 284 of the UE 120. As another example, the multi-band antenna module 405b can wrap around an edge of the UE 120 such that the multi-band antenna module 405b is located on a left side of the housing 284 of the UE 120 and on a back of the housing 284 of the UE 120.

[0098] As indicated above, Figures 4A-4C are provided as examples. Other examples can differ from what is described with respect to Figures 4A-4C the examples described with respect to the examples described with respect to

[0099] Figures 5A-5C is a diagram of an example of a multi-band antenna module 405 for high rank MIMO communications according to the present disclosure. The example of the antenna module 405 can be included in a UE 120, a network node 110, and / or another wireless communication device configured for high rank MIMO communications in a wireless network.

[0100] Figure 5A Example 500 of a multi-band antenna module 405 is illustrated, in which a low band antenna element 502 (e.g., antenna 252) and a mid-to-high (mid / high) band antenna element 504 (e.g., antenna 252) are included on the same substrate and / or printed with a planar printed circuit board (PCB) process. The example 500 of the multi-band antenna module 405 can be used in the example multi-band antenna module configurations illustrated. Figure 4A

[0101] The low band antenna element 502 can be configured for wireless communications on a FR2 band, a FR1 band, and / or another low band band. For example, the low band antenna element 502 can be configured for wireless communications on a band in a range of about 24 GHz to about 29.5 GHz. As another example, the low band antenna element 502 can be configured for wireless communications on a band in a range of about 28 GHz to about 39 GHz. In some aspects, the low band antenna element 502 can be dual-polarized phased and configured for wireless communications on two or more interlaced bands, such as 28 GHz and 39 GHz.

[0102] ​The mid / high-band antenna elements 504 can be configured for wireless communications over a FR3 band, a FR4 band, and / or another mid / high-band frequency band. For example, the mid / high-band antenna elements 504 can be configured for wireless communications over a frequency band in a range of about 57 GHz to about 71 GHz. As another example, the mid / high-band antenna elements 504 can be configured for wireless communications over a frequency band in a range of about 37 GHz to about 43.5 GHz. As another example, the mid / high-band antenna elements 504 can be configured for wireless communications over a frequency band in a range of about 47.2 GHz to about 48.2 GHz.

[0103] As shown in Figure 5A As further shown, the low-band antenna elements 502 and the mid / high-band antenna elements 504 can be arranged in a row on a substrate. The low-band antenna elements 502 can be configured as a 4x1 array (e.g., a 1 -row array including 4 antenna elements) or another array configuration. The mid / high-band antenna elements 504 can be configured as a 4x1 array (e.g., a 1 -row array including 4 antenna elements) or another array configuration. The low-band antenna elements 502 and the mid / high-band antenna elements 504 can be arranged in a row on the substrate in an alternating configuration.

[0104] As shown in Figure 5B As shown in example 510 of the multi-band antenna module 405 of FIG. 5B, the mid / high-band antenna elements 504 can be located at or near a corner of the low-band antenna elements 502. The low-band antenna elements 502 can be configured as a 4x1 array (e.g., a 1 -row array including 4 antenna elements) or another array configuration. The mid / high-band antenna elements 504 can be configured as an 8x2 array (e.g., a 2-row array including 8 antenna elements each) or another array configuration.

[0105] Figure 5C An example 520 of the multi-band antenna module 405 is illustrated, in which the low-band antenna elements 502 and the mid / high-band antenna elements 504 are included on different substrates and in different planes. For example, the low-band antenna elements 502 can be included on a first substrate located in a first plane, and the mid / high-band antenna elements 504 can be included on a second substrate located in a second plane. In some aspects, the first plane and the second plane can be approximately orthogonal planes. In some aspects, the first plane and the second plane can be separated by another angle (Q).

[0106] The example 520 of the multi-band antenna module 405 enables the multi-band antenna module 405 to wrap around a corner or edge (e.g., of the housing 284 of the UE 120) such that the multi-band antenna module 405 can be located on two sides and / or two faces of a wireless communication device. For example, the example 520 of the multi-band antenna module 405 can be located on two sides and / or two faces of a wireless communication device as shown in Figure 4B and Figure 4Cused in the example multi-band antenna module configurations illustrated above.

[0107] As indicated above, Figures 5A-5C are provided as examples. Other examples can differ from what is described Figures 5A-5C with respect to the examples described.

[0108] Figure 6A and Figure 6B is a diagram of an example 600 of capability signaling to support high rank MIMO communications according to the present disclosure. As Figure 6A and Figure 6B indicated, example 600 can include communication between a network node 110 and a UE 120. The network node 110 and UE 120 can be included in a wireless network, such as wireless network 100. The network node 110 and / or UE 120 can include one or more multi-band antenna modules 405 that enable high rank MIMO communications between the network node 110 and UE 120. The one or more multi-band antenna modules 405 can be configured as illustrated and described in one or more of the examples illustrated and described in connection with Figures 4A-4C and / or Figures 5A-5C and so forth.

[0109] As Figure 6A indicated, at 605, the UE 120 can transmit an indication of a capability to support high rank MIMO communications. The indication of the capability to support high rank MIMO communications can facilitate the network node 110 scheduling and / or configuring high rank MIMO communications between the network node 110 and UE 120. In some aspects, the indication of the capability to support high rank MIMO communications can include an indication of a capability to support high rank MIMO communications in substantially the same direction on two or more frequency bands having a common intermediate frequency. The two or more frequency bands can include, for example, a first frequency band (e.g., a FR2 frequency band or a frequency band in another frequency range) and a second frequency band (e.g., a FR3 frequency band, a FR4 frequency band, or a frequency band in another frequency range). The capability to support high rank MIMO communications includes a capability to support MIMO communications on more than two layers (typically polarization layers).

[0110] In some aspects, the UE 120 can transmit the indication of the capability to support high rank MIMO communications in substantially the same direction on the two or more frequency bands having the common intermediate frequency based at least in part on a spatial separation between a first multi-band antenna module 405 and a second multi-band antenna module 405 satisfying a spatial separation threshold. The spatial separation threshold can correspond to a Rayleigh distance (d Ray). The UE 120 can determine that the Rayleigh distance is satisfied for the first multi-band antenna module 405 and the second multi-band antenna module 405 by determining the Rayleigh distance (e.g., based at least in part on the Rayleigh distance equation described above), comparing a spatial separation between the first multi-band antenna module 405 and the second multi-band antenna module 405 to the Rayleigh distance, and determining whether the spatial separation satisfies the Rayleigh distance (for the first frequency band or the second frequency band) based at least in part on the comparison.

[0111] In some aspects, the UE 120 can transmit an indication of a number of hybrid beamforming beam weight sets to support for high rank MIMO communications (e.g., in addition to the indication of the capability). These hybrid beamforming beam weight sets can be used for RF / analog precoding. In this way, the indication of the number of hybrid beamforming beam weight sets can enable the network node 110 to select particular beam weights for RF / analog precoding for high rank MIMO communications. To support high rank MIMO communications, the number of hybrid beamforming beam weight sets to support can be greater than 2 to enable communications over more than 2 layers (e.g., spatial layers, polarization layers).

[0112] In some aspects, the UE 120 can measure and / or determine a spatial separation of at least two multi-band antenna modules 405 of the UE 120 for high rank MIMO in a plane orthogonal to a propagation direction of a signal between the UE 120 and the network node 110. If the UE 120 determines that there are more than 2 multi-band antenna modules 405 that can receive the same beam with a higher rank (e.g., with a rank greater than 2), the UE 120 reports all possible spatial separations or a subset of possible spatial separations (e.g., along with the indication of the capability). In some aspects, the UE 120 reports the largest possible spatial separation to the network node 110.

[0113] In some aspects, the rank indication generally includes an indication of associated DMRS ports. The UE 120 can transmit an indication of a number of DMRS ports associated with hybrid beamforming beam weight sets to support for high rank MIMO communications (e.g., in addition to the indication of the capability).

[0114] In some aspects, a high rank MIMO rate gain is a tradeoff for an increase in power consumption. Accordingly, the UE 120 can transmit an indication of one or more power and performance parameters for high rank MIMO communications (e.g., in addition to the indication of the capability). The UE 120 can report power and performance tradeoff parameters (e.g., along with the indication of the capability) to enable the network node 110 to select high rank MIMO communication parameters.

[0115] In Figure 6AAt 610, the network node 110 and / or the UE 120 can perform high rank MIMO communications based at least in part on the indication of the capability at 605. For example, the network node 110 can receive the indication of the capability from the UE 120 and can schedule, configure, and / or implement high rank MIMO communications for the UE 120 based at least in part on the indication of the capability. The network node 110 and / or the UE 120 can perform the high rank MIMO communications with the network node in substantially the same direction on the two or more frequency bands (e.g., which share the same intermediate frequency).

[0116] In some aspects, the high rank MIMO communications can include performing the high rank MIMO communications on a first frequency band of the two or more frequency bands using a first subset of antenna elements (e.g., antenna elements 502) on the first multi-band antenna module 405 and a first subset of antenna elements (e.g., antenna elements 502) on the second multi-band antenna module 405. In some aspects, the high rank MIMO communications can include performing the high rank MIMO communications on a second frequency band of the two or more frequency bands using a second subset of antenna elements (e.g., antenna elements 504) on the first multi-band antenna module 405 and a second subset of antenna elements (e.g., antenna elements 504) on the second multi-band antenna module 405.

[0117] In some aspects, the high rank MIMO communications include performing the high rank MIMO communications on a first frequency band of the two or more frequency bands using a first plurality of antenna elements (e.g., antenna elements 502) on the first multi-band antenna module 405 and performing the high rank MIMO communications on a second frequency band of the two or more frequency bands using a second plurality of antenna elements (e.g., antenna elements 504) on the second multi-band antenna module 405.

[0118] In some aspects, the high rank MIMO communications include performing the high rank MIMO communications on the first frequency band via two or more first spatial layers (e.g., layer 1 and layer 2) and performing the high rank MIMO communications on the second frequency band via two or more second spatial layers (e.g., layer 3 and layer 4).

[0119] Figure 6B A detailed example configuration of the high rank MIMO communications at 610 is illustrated. As Figure 6B As shown, the high rank MIMO communications can occur on two or more frequency bands (e.g., frequency band 1, frequency band 2) that share a common intermediate frequency. The antenna elements of the multi-band antenna modules 405 of the network node 110 and / or the UE 120 can have substantially the same boresight, substantially the same coverage direction, and / or substantially the same area, among other examples.

[0120] As Figure 6BAs shown, Tx Module 1 of network node 110 (e.g., first multi-band antenna module 405) and Tx Module 2 of network node 110 (e.g., second multi-band antenna module 405) can be spaced apart by a first Rayleigh distance (d Ray,1 ), to achieve uncorrelation at UE 120. Tx Module 3 of network node 110 (e.g., third multi-band antenna module 405) and Tx Module 4 of network node 110 (e.g., fourth multi-band antenna module 405) can be spaced apart by a second Rayleigh distance (d Ray,2 ), to achieve uncorrelation at UE 120.

[0121] As Figure 6B further shown, Tx Module 1 and Tx Module 2 can communicate with Rx Module 1 (e.g., first multi-band antenna module 405) on frequency band 1. Tx Module 3 and Tx Module 4 can communicate with Rx Module 2 (e.g., second multi-band antenna module 405) on frequency band 2.

[0122] Tx Modules 1 and 2 and Rx Module 1 can communicate via a first plurality of layers (Layers 0 through N-1 (e.g., spatial layers, polarization layers)). Tx Modules 3 and 4 and Rx Module 2 can communicate via a second plurality of layers (Layers N through N+M-1). The number of layers 0 through N+M-1 can be greater than 2 layers, which enables high rank MIMO communication between network node 110 and UE 120.

[0123] As indicated above, Figure 6A and Figure 6B are provided as examples. Other examples can differ from what is described with respect to the examples Figure 6A and Figure 6B described.

[0124] Figure 7 is a diagram illustrating an example process 700 performed, for example, by a UE, in accordance with the present disclosure. Example process 700 is an example where the UE (e.g., UE 120) performs operations associated with high rank multiple input multiple output communication for multi-band antenna module wireless communication devices.

[0125] As Figure 7 shown, in some aspects, process 700 can include transmitting, via a transceiver of the UE, an indication of a capability to support high rank MIMO communication on two or more frequency bands having a common intermediate frequency to a network node, where the capability to support the high rank MIMO communication includes a capability to support MIMO communication in substantially the same direction and on more than two layers (block 710). For example, the UE (e.g., using communication manager 160 and / or the like) can transmit, via a transceiver of the UE, an indication of a capability to support high rank MIMO communication on two or more frequency bands having a common intermediate frequency to a network node, where the capability to support the high rank MIMO communication includes a capability to support MIMO communication in substantially the same direction and on more than two layers. Figure 9The UE can transmit, to a network node via a transceiver of the UE, an indication of a capability to support high rank MIMO communications over two or more frequency bands having a common intermediate frequency, as described above, e.g., with reference to the transmission component 904 illustrated in FIG. 7. In some aspects, the capability to support the high rank MIMO communications includes a capability to support MIMO communications in substantially the same direction and over more than two layers (e.g., spatial layers, polarization layers). Figure 4A 、 Figure 4B 、 Figure 4C 、 Figure 6A and / or Figure 6B and / or the like. In some aspects, the capability to support the high rank MIMO communications includes a capability to support MIMO communications in substantially the same direction and over more than two layers (e.g., spatial layers, polarization layers).

Additionally or alternatively, two or more of the blocks of the process 700 can be performed in parallel.
