Description

[0001] open field

[0002] Various aspects of this disclosure generally relate to wireless communication, and specifically to techniques and apparatus for reporting beam type information for layered beamforming in wireless communication.

[0003] Related technical descriptions

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). 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 an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include several base stations (BSs) capable of supporting communication between several user equipments (UEs). UEs can communicate with the BS via downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as a B-node, gNB, access point (AP), radio headend, transmit / receive point (TRP), new radio (NR) BS, 5G B-node, etc.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL), and using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to grow. Summary of the Invention

[0048] Detailed description

[0049] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims.

[0050] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0051] It should be noted that although the aspects herein may be described using terms commonly associated with 5G or NR radio access technology (RAT), the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0052] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to various aspects of this disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc., or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, B-node, gNB, 5G B-node (NB), access point, transmit / receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0053] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UEs with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells may be referred to as a macro BS. A BS used for picocells may be referred to as a pico BS. A BS used for femtocells may be referred to as a femto BS or a home BS. Figure 1In the example shown, BS110a can be a macro BS for macro cell 102a, BS110b can be a pico BS for pico cell 102b, and BS110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “B node,” “5G NB,” and “cell” are used interchangeably herein.

[0054] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks, using any suitable transport network).

[0055] The wireless network 100 may also include a relay station. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS110d can communicate with macro BS110a and UE 120d to facilitate communication between BS110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0056] In some aspects, wireless network 100 may include one or more non-terrestrial network (NTN) deployments, wherein non-terrestrial wireless communication devices may include UEs (which are interchangeably referred to herein as “non-terrestrial UEs”), BSs (which are interchangeably referred to herein as “non-terrestrial BSs” and “non-terrestrial base stations”), relay stations (which are interchangeably referred to herein as “non-terrestrial relay stations”), and so on. As used herein, “NTN” may refer to a network to which access is facilitated by non-terrestrial UEs, non-terrestrial BSs, non-terrestrial relay stations, and so on.

[0057] Wireless Network 100 may include any number of non-terrestrial wireless communication devices. Non-terrestrial wireless communication devices may include satellites, manned aircraft systems, unmanned aerial vehicle system (UAS) platforms, etc. Satellites may include low Earth orbit (LEO) satellites, medium Earth orbit (MEO) satellites, geostationary orbit (GEO) satellites, highly elliptical orbit (HEO) satellites, etc. Manned aircraft systems may include aircraft, helicopters, airships, etc. UAS platforms may include high-altitude platform stations (HAPS) and may include balloons, airships, aircraft, etc. Non-terrestrial wireless communication devices may be part of an NTN separate from Wireless Network 100. Alternatively, the NTN may be part of Wireless Network 100. Satellites may communicate directly and / or indirectly with other entities in Wireless Network 100 using satellite communications. Other entities may include UEs (e.g., terrestrial UEs and / or non-terrestrial UEs), one or more other satellites in one or more NTN deployments, other types of BSs (e.g., stationary or terrestrial BSs), relay stations, one or more components and / or devices included in the core network of Wireless Network 100, etc.

[0058] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0059] Network controller 130 may be coupled to a set of Base Stations (BSs) and may provide coordination and control over these BSs. Network controller 130 may communicate with each BS via backhaul. These BSs may also communicate with each other directly or indirectly, for example, via wireless or wired backhaul. For example, in some aspects, wireless network 100 may be, include, or be included in a wireless backhaul network, sometimes referred to as an Integrated Access and Backhaul (IAB) network. In an IAB network, at least one base station (e.g., base station 110) may be an anchor base station that communicates with the core network via a wired backhaul link (such as a fiber optic connection). An anchor base station may also be referred to as an IAB donor (or IAB-donor), central entity, central unit, etc. An IAB network may include one or more non-anchor base stations (sometimes referred to as relay base stations or IAB nodes (or IAB-nodes)). Non-anchor base stations may communicate directly or indirectly with anchor base stations via one or more backhaul links (e.g., via one or more non-anchor base stations) to form backhaul paths to the core network for carrying backhaul traffic. The backhaul link may be a wireless link. Anchored base stations and / or non-anchored base stations may communicate with one or more UEs (e.g., UE 120) via an access link (which may be a radio link for carrying access traffic).

[0060] In some aspects, radio access networks, including IAB networks, can utilize millimeter-wave technology and / or directional communication (e.g., beamforming, precoding, etc.) for communication between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, a radio backhaul link between base stations can use millimeter waves to carry information and / or can use beamforming, precoding, etc., to point towards a target base station. Similarly, a radio access link between a UE and a base station can use millimeter waves and / or be directional towards a target radio node (e.g., the UE and / or the base station). In this way, inter-link interference can be reduced.

[0061] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0062] Some UEs may be considered machine-type communication (MTC) devices, or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes may provide connectivity to or to a network (e.g., a wide area network, such as the Internet or a cellular network) via wired or wireless communication links, for example. Some UEs may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included within a housing that houses components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0063] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0064] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this scenario, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0065] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) and / or an operating band with a second frequency range (FR2), where the first frequency range (FR1) spans from 410 MHz to 7.125 GHz and the second frequency range (FR2) spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU), FR2 is often referred to as the "millimeter wave" band. Therefore, unless otherwise stated, it should be understood that, if used herein, the terms "sub-6 GHz" and the like can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise stated, it should be understood that, if used herein, the terms "millimeter wave" and the like can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0066] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0067] Figure 2This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to various aspects of this disclosure. The base station 110 may be equipped with T antennas 234a to 234t, while the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T ≥ 1 and R ≥ 1.

[0068] At base station 110, transmit processor 220 can receive data destined for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0069] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or Channel Quality Indicator (CQI). In some respects, one or more components of the UE 120 may be included in the housing 284.

[0070] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0071] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or be included therein, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or multiple antenna elements within housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include elements coupled to one or more transmission and / or reception components (such as...). Figure 2 One or more antenna elements (one or more components).

[0072] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). Transmit processor 264 can also generate reference symbols for one or more reference signals.

[0080] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0081] Figure 3This is a diagram illustrating examples of wireless communication using beamforming according to various aspects of this disclosure. As shown, a first antenna array 310 and a second antenna array 320 can communicate with each other. In some aspects, the first antenna array 310 can be associated with a wireless communication device (e.g., a base station), and the second antenna array 320 can be associated with a wireless communication device (e.g., a UE). The first antenna array 310 and the second antenna array 320 can communicate using millimeter-wave networks.

[0082] As shown in the figure, the first antenna array 310 may include a large number of antenna elements. The second antenna array 320 may include several antenna modules (antenna module 1, antenna module 2, antenna module 3, and antenna module 4), each antenna module having a different associated coverage area. As a result, antenna arrays 310 and 320 may each include a large number of antenna dimensions. Due to the large number of antenna dimensions and the sparsity of the channels, directional beamforming processes can be used on different clusters in these channels, as shown in the figure.

[0083] To address the overhead in this type of directional beamforming, a layered beamforming method can be used. The layered beamforming method can be specified by a wireless communication standard. In a first aspect of the layered beamforming process (which may be referred to as "P-1"), a wide beam is used at a first antenna array 310 and a wide beam is used at a second antenna array 320. In a second aspect (which may be referred to as "P-2"), beam refinement is performed at the first antenna array 310 (e.g., at a base station), and in a third aspect (which may be referred to as "P-3"), beam refinement is performed at the second antenna array 320 (e.g., at a UE). Different beam types can be used in each aspect of the layered beamforming process, P-1, P-2, and P-3.

[0084] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0085] Figure 4 This is a diagram illustrating an example of plotting beamforming gain on a sphere having three different types of beams according to various aspects of this disclosure. As shown, the cumulative distribution function (CDF) of the beamforming array gain for each of the three different beam types is plotted.

[0086] In the illustrated example, a UE with a single antenna module at 60 GHz may have an 8x2 antenna array corresponding to a peak beamforming gain of approximately 14 dB, where 2 dB corresponds to the peak element gain and 12 dB corresponds to the array gain when using the 8x2 antenna array. The beamforming process may include a hybrid beamforming process performed in a layered beamforming manner, wherein a different beam type is used at each step of the layered beamforming hierarchy.

[0087] One type of beam described can include beams used for Layer 3 (L3) mobility (referred to as L3 mobility beams). L3 mobility beams can also be used for scanning neighboring cells and / or for handover, etc. These types of constant overhead processes can lead to significant power consumption, and reduced power consumption can result in the use of fewer antenna elements with lower beamforming gain. Another type of beam described is the peak performance beam type. Peak performance beams are used to achieve peak performance or the highest beamforming gain in connected-mode operation. Typically, peak performance beams use all antenna elements and consume the most power. An intermediate type of beam (which may be referred to as a "power-optimized" beam) lies between these L3 mobility beams and peak performance beams. Power-optimized beams achieve a trade-off between power and performance by using a set of more antenna elements than those used for L3 mobility beams but fewer than those used for peak performance beams.

[0088] like Figure 4 As illustrated in the diagram, array gain can vary between these beam types, and thus affect various aspects of communication, such as scheduling, reliability, and / or signal strength. Beamforming can involve weighting individual beam types. However, in some cases, information about beam types may not be reported from one device to another. As a result, devices may not be able to optimize the effectiveness of beamforming by taking into account the parameters affected by beamforming. This can lead to network performance degradation and / or communication efficiency degradation.

[0089] The techniques and apparatus described herein provide aspects of reporting beam type information. For example, in some aspects, a first wireless communication device may report beam type information to a second wireless communication device. Beam type information may include information about the number of beam types used, the number of beams per beam type, and / or parameters associated with beam performance (e.g., relative array gain). The first wireless communication device may use the reported beam type information to facilitate the execution of wireless communication actions, such as scheduling, establishing system communication parameters, and / or generating reference signals. In this way, some aspects may lead to improvements in network performance and / or communication efficiency.

[0090] As indicated above, Figure 4This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0091] Figure 5 This is a diagram illustrating examples related to beam type information reporting for layered beamforming in wireless communication, according to various aspects of this disclosure. As shown, a first wireless communication device 505 and a second wireless communication device 510 can communicate with each other. In some aspects, wireless communication device 505 and / or wireless communication device 510 may include a UE, a base station, a customer premises equipment (CPE), a sidelink node, a repeater (e.g., a smart repeater, an RF / dumb repeater, etc.), an IAB node, and / or a transmit / receive point, etc.

[0092] As indicated by reference numeral 515, wireless communication device 505 can transmit and wireless communication device 510 can receive beam type information reporting configuration. The beam type information reporting configuration can indicate the type of information to be reported, at least one beam type for which information about it is to be reported, the format for reporting the information, and / or reporting scheduling information, etc. For example, the number of beam types for which beam type information is to be reported can be configured.

[0093] Report scheduling information may include information about scheduling reporting events. For example, report scheduling information may indicate periodic reporting configuration, semi-persistent reporting configuration, repurposed resources for reporting beam type information, resource types for reporting beam type information, and / or conditions for reporting beam type information.

[0094] As indicated by reference numeral 520, wireless communication device 510 can transmit and wireless communication device 505 can receive beam type information. The beam type information may be associated with at least one beam used by wireless communication device 510 in a layered beamforming process. As indicated above, the layered beamforming process can be a layered beamforming process described in wireless communication standards. For example, the beamforming process may include a hybrid beamforming process performed in a layered beamforming manner, wherein different beam types are used at each step of the layered beamforming hierarchy. In some aspects, the layered beamforming process may be a simulated beamforming process. The layered beamforming process can be used for access link communication, IAB communication, and / or sidelink communication, etc.

[0095] In some aspects, the wireless communication device 510 may transmit beam type information at least in part based on determining the activation of the wireless communication device 510. For example, the wireless communication device 510 may be configured (e.g., through beam type configuration or other configuration procedures) to transmit beam type information upon activation (start-up). The beam type information may be carried, for example, in a capability field. In some aspects, the wireless communication device 510 may be configured to transmit beam type information at least in part based on establishing a connection with another device and / or network.

[0096] In some respects, beam type information may be transmitted at least in part based on determining an updated beam type. For example, wireless communication device 510 may determine that a beam type not yet used by wireless communication device 510 should be used and can begin to be used with the determined beam type. This may be an example of beam type updating, and wireless communication device 510 may transmit beam type information at least in part based on determining a beam type update (e.g., determining that a beam needs to be updated, determining that a beam type has been activated).

[0097] In some aspects, wireless communication device 510 may transmit beam type information to wireless communication device 505 based at least in part on a request for beam type information received from wireless communication device 505. This request may be part of the beam type information configuration. The request may be dynamic and may be transmitted to wireless communication device 510 based at least in part on determining that a communication link has degraded to a specified amount, one of the devices has been moved, etc.

[0098] In some aspects, beam type information may include an indication of the number of beam types used in the layered beamforming process. The beam type information may include an indication of the number of beams for each beam type used in the layered beamforming process. The total number of beams may be derived from this information and / or explicitly indicated in the beam type information. In some aspects, the beam types used and / or indicated may be at least partially based on the antenna array architecture of the wireless communication device 510. Beam types may include, for example, L3 mobility beam types, peak performance beam types, and / or power-optimized performance beam types. In some aspects, the number of beams used for each beam type may be any number and may depend on the antenna array architecture (e.g., array geometry, size, azimuth and / or elevation spacing between antenna elements, number of antenna modules, number of antenna panels, frequencies covered). The number of beams for each beam type may vary between different device types (e.g., UE, base station, CPE, high-mobility device, low-mobility device).

[0099] In some aspects, beam type information may include at least one parameter associated with the relative array gain across beams corresponding to those beam types. For example, beam type information may include at least one parameter associated with the relative array gain relative to a second beam type corresponding to a first beam type. In some aspects, the at least one parameter associated with the relative array gain may include the effective isotropic radiated power (EIRP) difference across beams corresponding to those beam types.

[0100] In some aspects, the at least one parameter may include one or more statistics (e.g., maximum, median, average, 90th percentile) associated with array gain improvement from one beam type to another. In some aspects, the at least one parameter may be expressed as a relative number of antenna dimensions per azimuth and / or elevation for each beam type, or an effective number of antenna dimensions per azimuth and / or elevation for each beam type. In other words, instead of capturing the array gain of one beam type relative to another, equivalent information can be expressed in the sense of changes in antenna dimensions that can be associated with changes in array gain. For example, in some aspects, beam type information may include an indication that the at least one parameter corresponds to at least one of the following: a relative number of antenna dimensions for each of a plurality of beam types; or an effective number of antenna dimensions for each of a plurality of beam types.

[0101] In some aspects, beam type information may include an indication that the at least one parameter corresponds to at least one of: an antenna panel, an antenna module, a coverage area of ​​the antenna panel, or a coverage area of ​​the antenna module. In some aspects, beam type information may include an indication that the at least one parameter corresponds to a frequency range of coverage associated with the antenna module.

[0102] As indicated by reference numeral 525, wireless communication device 505 may perform wireless communication actions at least in part based on beam type information. For example, in some aspects, wireless communication actions may include scheduling resources for wireless communication device 510. Beam type information may be used to inform scheduling decisions. For example, wireless communication device 505 may be able to use beam type information to determine beamforming gain and / or predict interference (e.g., sidelobes or grating lobes), etc. In some aspects, wireless communication actions may include scheduling and / or transmitting reference signals. In some aspects, wireless communication actions may include establishing system parameters. System parameters may include, for example, modulation and coding scheme (MCS), decoding rate, and / or transmit power, etc.

[0103] As indicated by reference numeral 530, wireless communication device 510 can communicate over a wireless communication network, at least in part, based on beam type information. In some aspects, wireless communication device 510 can communicate with wireless communication device 505. In some aspects, wireless communication device 510 can communicate with...
