[0003] The following relates generally to wireless communications, and more particularly to quasi co-location (QCL) and the configuration of the number of antenna elements. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems that may be referred to as new radio (NR) systems. These systems may use various technologies, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform extended orthogonal frequency division multiplexing (DFT-s-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting the communication of multiple communication devices, which may be referred to as user equipment (UE) in addition.

[0053] In some deployments, wireless communication systems may operate in the millimeter wave (mmW) frequency range (24 gigahertz (GHz), 26 GHz, 28 GHz, 39 GHz, 52.6–71 GHz, etc.). Wireless communication at these frequencies may be associated with increased signal attenuation (e.g., path loss, penetration loss, obstacle loss), which may be affected by various factors, such as diffraction, propagation environment, obstacle density, material properties, etc. As a result, signal processing techniques (such as beamforming) may be used to coherently combine energy and overcome path losses at these frequencies. Due to the increased amount of path, penetration, and obstacle losses in mmW communication systems, transmissions between wireless devices (e.g., from a base station or UE) may be beamformed.

[0054] In addition, the receiving device can use beamforming technology to configure (antennas), (antenna elements), (antenna arrays) or (antenna array modules) so that transmissions are received in a directional manner. For example, a wireless device can use an antenna array (e.g., a phased array antenna system) to generate a directional beam to transmit or receive transmissions in different or specific directions via the configuration of one or more antenna elements. In some cases, the wireless device can configure phase or amplitude parameters for one or more corresponding antenna elements of the antenna array, and the antenna element can apply the configured phase or amplitude parameters to convey the corresponding element signal. The antenna array can generate a directional communication beam as a composite of the element signals from each antenna element. In some examples, a directional communication beam can be generated by manipulating, for example, the relationship between the phase or amplitude of each of the corresponding antenna elements. The antenna elements of such an antenna array can be arranged in various configurations to facilitate forming such a directional beam into a composite of element signals. For example, the antenna element can be configured according to a first type (e.g., regular) antenna array structure (e.g., a linear, planar or circular arrangement of antenna elements). Additionally or alternatively, the antenna elements may be configured according to a second type (e.g., irregular) of antenna array structures (e.g., a random or pseudo-random set (e.g., a subset) of antenna elements from a set of available antenna elements to be excited for transmission or reception). According to the techniques described herein, the antenna elements may be configured in any configuration that may facilitate beamformed communication. As described herein, a set of antenna elements, antenna elements in a subarray, antenna elements in an array (or antenna array), and similar terms may each refer to and apply to the first type of antenna array structures and the second type of antenna array structures.

[0055] In some cases, a first device (e.g., a UE or other communication device) may operate according to a specific configuration for one or more of its antenna element sets. For example, the first device may communicate with a second device (e.g., a base station or other communication device) using a subset of the antenna element set (e.g., one or more antenna arrays or subarrays) of the first device. Additionally or alternatively, in some cases, the QCL configuration may indicate QCL information or spatial relationship information for one or more antenna element sets of the first device, which may indicate that the corresponding signals may have a QCL relationship (e.g., the antenna ports used to convey the corresponding signals may share one or more characteristics, such as one or more spatial characteristics). For example, according to a specific QCL type, the corresponding antenna element sets may share common beam characteristics, such as beam direction, beam width, beam identifier, spatial stream, and other spatial parameters. In some examples, the beam configuration may be referred to as a beam indication, a beam indication of a resource, or some similar term. In some cases, if multiple physical channels share beam characteristics so that one channel can be derived from another channel, the physical channels may be referred to as having a QCL relationship (which may be referred to as "quasi-co-located").

[0056] In some cases, the first device may change state (e.g., transmission configuration indication (TCI) state) to account for various conditions. For example, the first device may change state and, in doing so, change the antenna element configuration of the first device to use a different number of antenna elements, a different geometry, or different antenna element properties (e.g., gain, coupling, coverage according to an element gain pattern, and other similar properties). Additionally or alternatively, in the state change, the first device may change the QCL configuration of the first device to use a set of antenna elements (e.g., of one or more antenna arrays or subarrays) having a different QCL relationship than the set of antenna elements previously being used by the first device. In some examples, the state change may include a change in the QCL configuration or antenna configuration (e.g., the number of antenna elements to be used), which may correspond to the first device switching to a new beam.

[0057] The first device may switch beams in this manner based on the occurrence of one or more of various conditions or situations. For example, the first device may measure a signal quality metric (e.g., signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), received signal strength (RSS), reference signal received power (RSRP), reference signal received quality (RSRQ), etc.), and the first device may determine that the measured value of the signal quality metric exceeds a configured (e.g., pre-configured) value (such as a signal quality threshold). Based on the measured value of the signal quality metric exceeding the signal quality threshold, for example, the UE may change state to use a new QCL configuration or a new set of antenna elements, where the new configuration may provide improved signal quality or other similar performance improvements. For example, if the first device detects degraded signal quality, the first device may switch to a different configuration to increase the link budget and correspondingly increase the likelihood that the first device can successfully communicate with the second device. Additionally or alternatively, the first device may determine to change the configuration based on thermal characteristics of the first device, power characteristics of the first device, and other physical characteristics of the first device. For example, the first device may determine to change the configuration to improve the thermal performance of the first device (or a second device communicating with the first device).

[0058] According to the various techniques described herein, a first device may communicate with a second device, and the first device may determine a change state, for example, based on a metric (e.g., a performance metric, a signal quality metric, etc.) satisfying a specific condition associated with communication between the first device and the second device (e.g., the metric exceeds a corresponding threshold). The first device may transmit a signal including a state change request to the second device to indicate that the first device is changing state to use a different configuration, for example, to use a different antenna configuration (e.g., a configuration for a different set of antenna elements) or a different QCL configuration using an increased or decreased number of antenna elements. Based on the signal indicating the change of state of the first device, the second device may adjust one or more parameters or configurations of its antenna array accordingly. For example, the second device may increase or decrease the MCS or transmit power according to the new configuration indicated by the first device to utilize the increased or decreased available link budget. The second device may transmit a signal indicating its corresponding adjustment for its antenna array back to the first device, and the first device and the second device may communicate according to the updated configuration.

[0059] Various aspects of the present disclosure are initially described in the context of a wireless communication system. Various examples of antenna modules, antenna element groups, and process flows are then described. Various aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to adjusting communication operations for changes in configuration for QCL and number of antenna elements.

[0060] Figure 1An example of a wireless communication system 100 that supports adjusting communication operations for changes in configurations for QCL and number of antenna elements according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be an LTE network, an LTE-A network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0061] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be different forms of devices or devices with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support signal communication according to one or more radio access technologies.

[0062] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be different forms of devices or devices with different capabilities. Figure 1 115. The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, repeater devices, CPE, IAB nodes, router devices, or other network equipment), such as Figure 1 as shown in .

[0063] Each base station 105 may communicate with the core network 130, or communicate with each other, or both. For example, the base station 105 may be connected to the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3 or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105), or indirectly (e.g., via the core network 130), or directly and indirectly on the backhaul link 120 (e.g., via X2, Xn or other interfaces). In some examples, the backhaul link 120 may be or include one or more wireless links. In some examples, one or more base stations 105 may provide backhaul connectivity between another base station 105 and the core network 130 via a backhaul link 160 when acting as an IAB node. The UE 115 may communicate with the core network 130 via a communication link 155.

[0064] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a B node, an evolved B node (eNB), a next generation B node or a gigabit B node (any of which may be referred to as a gNB), a home B node, a home evolved B node, or other suitable terminology.

[0065] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as electrical appliances or vehicles, meters, etc.

[0066] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115 that may sometimes act as relays, routers, or CPE, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, IAB nodes, relay base stations, etc. Figure 1 as shown in .

[0067] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0068] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in an FDD mode), or may be configured to carry both downlink and uplink communications (e.g., in a TDD mode).

[0069] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) of a carrier of a particular radio access technology. Devices (e.g., base stations 105, UEs 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configurable to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., subband, BWP) or all of a carrier bandwidth.

[0070] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or DFT-s-OFDM). In a system using MCM technology, a resource element may include a code element period (e.g., the duration of a modulation code element) and a subcarrier, where the code element period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity of communication with UE 115.

[0071] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, and the basic time unit can be, for example, a sampling period T s =1 / (Δf max ·Nf) seconds, where Δf max Nf may represent the maximum supported subcarrier spacing, and Nf may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0072] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of code element periods (e.g., depending on the length of the cyclic prefix added before each code element period). In some wireless communication systems 100, the time slot may be further divided into a plurality of mini-time slots containing one or more code elements. Excluding the cyclic prefix, each code element period may include one or more (e.g., Nf) sampling periods. The duration of the code element period may depend on the subcarrier spacing or the operating frequency band.

[0073] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0074] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0075] In some examples, base stations 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0076] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0077] The wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication or group communication, and may be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low latency, critical mission, and ultra-reliable low latency may be used interchangeably herein.

[0078] In some examples, UE 115 may also be able to communicate directly with other UE 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some examples, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between each UE 115 without involving the base station 105.

[0079] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these communications. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can use vehicle-to-network (V2N) communications to communicate with roadside infrastructure (such as roadside units), or with the network, or both via one or more network nodes (e.g., base station 105).

[0080] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and the EPC or 5GC may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access layer (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a base station 105 associated with the core network 130. User IP packets may be delivered through a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0081] Some network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).

[0082] The wireless communication system 100 may operate using one or more frequency bands, such as in the range of 300 MHz to 300 GHz. The 300 MHz to 3 GHz region may be referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features, but these waves may penetrate various structures sufficiently for macro cells to provide service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmission using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0083] The wireless communication system 100 may also operate in a super high frequency (SHF) zone using a frequency band from 3 GHz to 30 GHz (also known as a centimeter band) or in an extremely high frequency (EHF) zone of a spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antenna of the corresponding device may be smaller and more closely spaced than the UHF antenna. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency zones, and the use of frequency bands specified across these frequency zones may vary by country or regulatory agency.

[0084] The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. Similar naming issues sometimes arise with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in various documents and articles, although it is different from the EHF band (30 GHz–300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0085] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands of these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to above 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.

[0086] In view of the above aspects, unless otherwise specifically stated, it should be understood that if used in this document, the term "sub-6 GHz" and the like can broadly refer to frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if used in this document, the term "millimeter wave" and the like can broadly 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.

[0087] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) may employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in a licensed band. Operations in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0088] The base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having antenna ports of several rows and columns that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0089] The base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0090] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0091] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or a receiving device (such as the UE 115)) to identify a beam direction used by the base station 105 for later transmission or reception.

[0092] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a recipient device, such as UE 115. In some examples, a beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0093] In some examples, transmission by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may transmit a reference signal that may be precoded or uncoded (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)). The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0094] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may try multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, SNR, SINR, RSS, RSRP, RSRQ, or other acceptable signal quality based on listening according to multiple beam directions).

[0095] UE 115 may include one or more antenna modules, each of which may include a relatively large number of antenna elements for mmW communications. UE communication manager 101 may manage mmW communications, and in some cases, may use the various techniques described herein to communicate with a second device (e.g., base station 105). In some cases, UE 115 may determine to change a configuration state, for example, based on a metric (e.g., a performance metric, a signal quality metric, etc.) satisfying a particular condition (e.g., the metric exceeds a corresponding threshold). UE 115 may transmit a signal to the second device to indicate that UE 115 is changing state to use a different configuration, for example, to use a different antenna configuration or a different QCL configuration that employs an increased or decreased number of antenna elements.

[0096] One or more of the base stations 105 may be examples of second devices discussed herein and may include a base station communication manager 102. The base station communication manager 102 may receive a signal indicating a change in state of the UE 115 and may correspondingly adjust one or more parameters, configurations, or both of one or more sets of antenna elements for the second device. The base station communication manager 102 may transmit a signal indicating the adjustments performed for these sets of antenna elements for the second device back to the UE, and the first device and the second device may communicate according to the updated configuration.

[0097] Figure 2An example of a communication device 200 that supports adjusting communication operations for changes in configuration for QCL and number of antenna elements 225 in accordance with one or more aspects of the present disclosure is illustrated. In some examples, a communication device 200 with multiple antenna arrays can implement aspects of a wireless communication system 100. In this example, the communication device is illustrated as a UE 115-a, although in other cases, the communication device can be a different device, such as a CPE, a relay device, a router, a repeater, or an IAB node.

[0098] In this example, UE 115-a includes several different antenna modules, including a first antenna module 205, a second antenna module 210, and a third antenna module 215. Each of antenna modules 205, 210, and 215 may include an antenna array, which in turn may include a subarray 220 of several antenna elements 225. Figure 2 In the illustrative example of, the first antenna module 205 may include four sub-arrays 220, including a first sub-array 220-a, a second sub-array 220-b, a third sub-array 220-c, and a fourth sub-array 220-d. In this example, each sub-array 220 may include 16 separate antenna elements 225 arranged in a 4x4 antenna configuration. In some cases, each of the antenna elements 225 may be a patch antenna configured to communicate in a high-band mmW deployment. In some cases, the spacing of the antenna elements 225 within each sub-array 220 may be configured to provide efficient analog beamforming at a wavelength associated with high-band mmW communications.

[0099] exist Figure 2 In the illustrative example of FIG, the first antenna module 205 is illustrated as having four sub-arrays 220, wherein each sub-array 220 has antenna elements 225 in a 4x4 configuration. The second antenna module 210 may also include one or more corresponding sub-arrays 220, such as a fifth sub-array 220-e and a sixth sub-array 220-f. Figure 2 As shown in the illustrative example of , the fifth subarray 220-e includes a set of eight antenna elements 225 arranged in a 4x2 configuration, and the sixth subarray 220-f includes a set of four antenna elements 225 arranged in a 4x1 configuration. In some cases, these configurations for antenna array sets may be referred to interchangeably as antenna configurations, antenna element configurations, antenna array configurations, and other similar terms.

[0100] As in Figure 2As shown in the illustrative example of , a radio frequency integrated circuit (RFIC) 240 (e.g., operating according to a configured protocol such as RFIC5) can be coupled to the fifth subarray 220-e and the sixth subarray 220-f. In some cases, multiple RFICs can be used, or one RFIC can be shared with one or more others of the antenna modules 205 or 215. Although the antenna module 210 is illustrated as having multiple subarrays 220 of different sizes, in other examples, the antenna module 210 can be configured to have a number of subarrays 220, where each subarray 220 has the same size (e.g., four 4x4 antenna subarrays 220, as similarly illustrated with respect to the first antenna module 205). In accordance with the techniques described herein, the communication device 200 can include and implement the described techniques using any number of antenna modules 205-215, which can include any number of sub-arrays 220, which can each include one or more sets of antenna elements 225, and each set of antenna elements 225 of the sub-arrays 220 can include any number of antenna elements 225 per sub-array 220, and any similar combinations thereof.

[0101] The techniques discussed herein can be applied to any number of antenna modules 205 to 215, any number of subarrays 220 included in each antenna module, any number of antennas per subarray 220, or any combination thereof. For example, in an FR2 deployment, a wireless device may be configured with a relatively small antenna array (e.g., antenna elements 225 in a 4x1 to 6x1 configuration). Alternatively, in other deployments, a wireless device may be configured with a relatively large antenna array (e.g., for use in a deployment of sub-6 GHz or mmW carrier frequencies). Such a relatively large antenna array may be used at a base station, in which case the antenna array may have relatively less stringent physical constraints (e.g., power, thermal, or other physical constraints).

[0102] However, in other deployments, wireless communication devices 200 (such as UE 115-a) may utilize these relatively large antenna arrays. These devices (e.g., CPE, relay devices, routers, repeaters, IAB nodes, etc.) may have varying capabilities and configurations (e.g., form factors). For example, these devices may sometimes be powered by battery power, may be configured as mobile form factors, may have specific size constraints, etc., such that improvements in power and thermal efficiency may be beneficial (e.g., providing longer operating life before recharging the battery).

[0103] In some cases, the UE 115-a may operate according to a specific configuration for its antenna array and subarray. For example, the UE 115-a may operate according to a selected TCI state (e.g., a TCI state to be used at a base station) with reference to a second device with which the UE 115-a can communicate. According to a specific TCI state, the UE 115-a may use a given subset of antenna elements 225 of a specific plurality of the subarrays 220 of the UE 115-a. Additionally or alternatively, in some cases, the QCL configuration may indicate given QCL information or spatial relationship information (such as different QCL types). The QCL information may indicate that different signals may have a QCL relationship (e.g., antenna ports used to transmit corresponding signals may share one or more characteristics, such as one or more spatial characteristics). For example, a physical downlink shared channel (PDSCH) and a PDCCH that share beam characteristics so that one can be derived from the other may be referred to as having a QCL relationship (which may be referred to as "quasi-co-located"). That is, the beam characteristics of the PDCCH are derived from the knowledge of the beam characteristics of the PDSCH and the QCL relationship (or vice versa). Figure 2 In an example of FIG. 1 , antenna elements 225 of each subarray 220 may be QCL antenna elements 225. For example, a first QCL configuration associated with subarray 220-a may indicate that signals received at each antenna element 225 of subarray 220-a may have a QCL relationship (e.g., each antenna element 225 of subarray 220-a may share one or more characteristics, such as spatial characteristics).

[0104] In some cases, the UE 115-a may suggest (e.g., to the base station) a change in state (e.g., TCI state) to account for various conditions. For example, in such a state change, the UE 115-a may change its antenna configuration (or antenna array configuration) to use a different number of antenna elements 225. Additionally or alternatively, in the state change, the UE 115-a may suggest a change in its QCL configuration to use a set of antenna elements 225 with different QCL relationships. Such a state change, including a change in the QCL configuration or antenna configuration (e.g., the number of antenna elements 225 to be used), may correspond to the UE 115-a switching to a new beam (e.g., to communicate with another communication device (such as a different base station or transmission point), or to target a different cluster or ray or path within the same channel as the base station or transmitting node). The UE 115-a may switch beams in this manner based on the occurrence of various conditions or situations. In some cases, the conditions for UE 115-a to switch beams can be based on signal quality, throughput, or other communication metrics. For example, UE 115-a can measure a signal quality metric (e.g., SNR, SINR, RSS, RSRP, RSRQ, etc.), and UE 115-a can determine that the measured value of the signal quality metric exceeds a configured (e.g., pre-configured) value (such as a signal quality threshold). Based on the measured value of the signal quality metric exceeding the signal quality threshold, for example, UE 115-a can change the state accordingly to use a new QCL configuration or antenna element 225, where the new configuration can provide improved signal quality or other similar performance improvements. This change in condition can occur due to changing channel conditions, physical interference or obstruction, and other dynamic conditions in the vicinity of UE115-a or in the wireless network. For example, if the signal quality degrades, UE 115-a can switch to a new configuration to increase the link budget, thereby increasing the likelihood that UE115-a can successfully transmit and receive transmissions.

[0105] Additionally or alternatively, the UE 115-a may determine to change configuration (e.g., to improve power or rate control for communication) based on thermal characteristics of the UE 115-a, power characteristics of the UE 115-a, and other similar physical characteristics of the UE 115-a that may change over time. For example, the UE 115-a may identify that a thermal metric exceeds a corresponding threshold (e.g., a thermal performance threshold), and the UE 115-a may determine to change state to use a new QCL configuration or antenna element 225 to achieve improved thermal performance (or, for example, battery performance, etc.). Additionally or alternatively, the UE 115-a may identify a metric (e.g., regarding signal quality, throughput, thermal performance, etc.) of a device with which the UE 115-a is communicating, and the UE 115-a may change state based on the metric of the other device. For example, in order to improve performance at a nearby node with which the UE 115-a is communicating, the UE 115-a may determine to change configuration to improve thermal performance while potentially reducing throughput for communicating with the node. Conversely, UE 115 - a may determine to change configuration to improve signal quality or throughput while potentially reducing thermal performance of the node.

[0106] According to the techniques described herein, UE 115-a may be communicating with a second device (e.g., a base station), and UE 115-a may determine to change state, for example, based on a metric (e.g., a performance metric, a signal quality metric, etc.) satisfying a specific condition (e.g., a metric exceeds a corresponding threshold). UE 115-a may transmit a signal to the second device to indicate that UE 115-a is changing state to use a different configuration, such as to use a different antenna configuration or a different QCL configuration using an increased or decreased number of antenna elements 225. The signal may indicate the grouping of the antenna elements 225 used, the number of antenna elements used, the QCL configuration used, or a combination thereof. Based on the signal indicating the change in state of UE 115-a, the second device may adjust one or more parameters, configuration, or both of its antenna array. Therefore, the techniques described herein may provide improved communication reliability and link quality between communication devices.

[0107] Figure 3 An example configuration 300 of an antenna array that supports adjusting communication operations for changes in configuration of QCL and number of antenna elements according to one or more aspects of the present disclosure is illustrated. In some examples, the example configuration 300 of the antenna array can be implemented as described with reference to Figure 1 Aspects of wireless communication system 100 are described. Figure 3The configuration 300 shows example changes of the antenna configuration according to three examples (including a first example 305, a second example 310, and a third example 315). Each of the examples 305, 310, and 315 shows an antenna array including two antenna subarrays 320, each of which can be as shown in reference Figure 2 Examples of aspects of an antenna module of a communication device 200 (such as a UE) are described. Each of the antenna subarrays 320 is shown as a 4x4 subarray including 16 antenna elements 325, although any other similar antenna element 325 configuration is similarly contemplated. Examples 305, 310, and 315 illustrate a transition from a first time ("time 1") to a second time ("time 2"), where time 2 is after time 1, as indicated by the directional arrows.

[0108] In a first example 305, the antenna array of the UE may include a first antenna subarray 320-a and a second antenna subarray 320-b. At time 1, the UE may be communicating using a beam formed by using each of the 16 antenna elements 325 of the second antenna subarray 320-b and not using the antenna elements 325 of the first antenna subarray 320-a. As a result, signals received at or transmitted by each of the 16 antenna elements 325 of the second antenna subarray 320-b may share a QCL relationship. The UE may determine whether to perform a state change, for example, based on one or more of a signal quality metric, a thermal characteristic, a power characteristic, or other metric, as described herein. According to the first example 305, the UE may determine that the transmission beam provides sufficient performance for the UE (e.g., by identifying that the metric meets (or is below) a corresponding threshold), and therefore the UE may determine to continue transmitting using the same antenna elements 325 of the second antenna subarray 320-b at time 2, while the antenna elements 325 of the first antenna subarray 320-a may remain inactive. Thus, in the first example 305, the UE may not change the QCL configuration or change the number of antenna elements 325. The QCL configuration may not change because the UE may continue to transmit using the same set of antenna elements 325 of the second antenna subarray 320-b at time 2.

[0109] In a second example 310, the antenna array of the UE may include a first antenna subarray 320-c and a second antenna subarray 320-d. At time 1, the UE may be communicating using a beam formed by using each of the 16 antenna elements 325 of the second antenna subarray 320-d and not using the antenna elements 325 of the first antenna subarray 320-c. The UE may determine whether to perform a state change, for example, based on a signal quality metric, a thermal characteristic, a power characteristic, or other metric, as described herein. According to the second example 310, the UE may determine to change the transmission beam from the configuration at time 1 (e.g., based on identifying that the metric is below (or exceeds) a corresponding threshold). Therefore, the UE may determine a new antenna configuration (e.g., an antenna array configuration). For example, as shown in the second example 310, the UE may determine to use a 4x2 configuration of the antenna elements 325 of the second antenna subarray 320-d at time 2 (e.g., to reduce power consumption or thermal output at the UE). Thus, in the second example 310, the UE may not change the QCL configuration, but may change the antenna configuration to reduce the number of active antenna elements 325. The QCL configuration of the UE may not change because the antenna elements 325 of the 4x2 configuration of the second antenna subarray 320-d may include antenna elements previously used by the UE. Thus, the QCL relationship between signals transmitted by or received at the antenna elements 325 may be maintained.

[0110] In a third example 315, the antenna array of the UE may include a first antenna subarray 320-e and a second antenna subarray 320-f. At time 1, the UE may be communicating using a beam formed by using each of the 16 antenna elements 325 of the second antenna subarray 320-f and not using the antenna elements 325 of the first antenna subarray 320-e. The UE may determine whether to perform a state change, for example, based on a signal quality metric, a thermal characteristic, a power characteristic, or other metric, as described herein. According to the third example 315, the UE may determine to change the transmission beam from the configuration at time 1 (e.g., based on identifying that the metric is below (or exceeds) a corresponding threshold). Therefore, the UE may determine a new antenna configuration. For example, as shown in the third example 315, the UE may determine to use the 2x4 configured antenna elements 325 of both the first antenna subarray 320-e and the second antenna subarray 320-f at time 2. When activating antenna elements 325 of the first antenna subarray 320-e, the UE may change the QCL relationship of the beam at time 2 relative to time 1 (e.g., because the QCL configuration of antenna elements 325 of the first antenna subarray 320-e may be different from the QCL configuration of antenna elements 325 of the second antenna subarray 320-f). Thus, in the third example 315, the UE may change both the QCL configuration and the antenna configuration while reducing the number of active antenna elements 325.

[0111] According to the second example 310 and the third example 315, the UE may transmit a signal to a second device (e.g., a second device with which the UE communicates at time 1 and time 2) to indicate a new configuration (e.g., a QCL configuration or an antenna configuration) for the UE. This may indicate that the UE is changing state to use a new configuration, such as to use a different antenna configuration or a different QCL configuration that uses a reduced (or in other examples, increased) number of antenna elements. Based on the signal indicating the change in state of the UE, the second device may also adjust one or more parameters, configurations, or both of the antenna array of the second device. For example, the second device may increase or decrease the MCS or transmit power according to the new configuration indicated by the UE to utilize a reduced (or in other examples, increased) link budget. According to the technology described in the present invention, the second device may transmit a signal indicating the corresponding adjustment at the second device back to the UE, and the UE and the second device may communicate according to the updated configuration. Therefore, the technology described herein may provide improved communication reliability and link quality between communication devices.

[0112] Figure 4 An example of a wireless communication system 400 that supports adjusting communication operations for changes in configuration of QCL and number of antenna elements according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 400 may implement as described with reference to Figure 1 In some examples, the wireless communication system 400 may include a base station 105-a and a UE 115-b, which may be referenced Figures 1 to 3 1 and 105-a. UE 115-b may be an example of a first device and base station 105-a may be an example of a second device, as described herein. UE 115-b and base station 105-a may communicate using beamformed communications, wherein UE 115-b transmits uplink communications 405 to base station 105-a and base station 105-a transmits downlink communications 410 to UE 115-b.

[0113] In some cases, UE 115-b may include a relatively large number of antenna elements, which may be distributed across one or more antenna subarrays and one or more antenna modules of UE 115-b. As similarly described herein, UE 115-b may determine to change state, for example, based on a metric (e.g., a performance metric, a signal quality metric, etc.) satisfying a particular condition (e.g., the metric exceeds a corresponding threshold). UE 115-b may transmit a signal including a state change request 415 to base station 105-a to indicate that UE 115-b is changing state to use a different configuration, such as to use a different antenna configuration (e.g., an antenna array configuration) or a different QCL configuration (e.g., correspondingly increase or decrease the available link budget for communication between UE 115-b and base station 105-a), the different antenna configuration employing an increased or decreased number of antenna elements. State change request 415 may indicate to base station 105-a to update the configuration accordingly to utilize the updated (e.g., increased or decreased) link budget. For example, a greater number of antenna elements may provide a relatively increased equivalent isotropic radiated power (EIRP) for transmissions from UE 115 - b , which may correspondingly provide a relatively increased link budget for communications between UE 115 - b and base station 105 - a .

[0114] Based on the state change request 415 indicating a change in state of the UE 115-b, the base station 105-a may adjust one or more parameters, configurations, or both of a communication beam for the antenna array of the base station 105-a. For example, the indicated configuration may indicate that the base station 105-a may use a configuration with an increased code rate or transmit power. Accordingly, the base station 105-a may perform adjustments to increase the MCS or transmit power to utilize an increased link budget that is available based on the updated configuration indicated by the UE 115-b via the state change request 415. For example, the base station 105-a may increase the MCS from 16 quadrature amplitude modulation (16QAM) to 64 quadrature amplitude modulation (64QAM), as accommodated by the larger link budget.

[0115] In some cases, in response to receiving the state change request 415 from the UE 115-b and adjusting the configuration of an antenna array (or antenna arrays) for the base station 105-a, the base station 105-a may transmit a response message 420 to the UE 115-b. In some cases, the base station 105-a may transmit the state change request 415 to the UE 115-b in control signaling (e.g., in a control channel transmission (such as in an uplink control channel (e.g., PUCCH), a downlink control channel (e.g., PDCCH), or a sidelink control channel transmission) or in a MAC-CE). Additionally or alternatively, the base station 105-a may transmit the state change request 415 to the UE 115-b via RRC signaling.

[0116] The response message 420 may indicate a particular adjustment or adjustments performed by the base station 105-a such that the UE 115-b is notified of, for example, an updated MCS with which to continue communicating with the base station 105-a. Similarly, the response message 420 may indicate an updated transmit power, which the UE 115-b may use to perform subsequent measurements, for example, to perform additional signal quality measurements based on its UE 115-b switchable state again, as similarly described herein. Thus, the UE 115-b and the base station 105-a may dynamically update and signal QCL configurations and antenna configuration (e.g., antenna array configuration) updates to efficiently configure communication beams to achieve desired thermal (e.g., battery) performance relative to signal quality and throughput performance.

[0117] Figure 5 An example of a process flow 500 for supporting adjustment of communication operations for changes in configuration of QCL and number of antenna elements according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 500 may be correspondingly performed as described with reference to Figure 1 and 4 The process flow 500 may include a first device 505 and a second device 510, which may be referenced to Figure 1 and 2 Examples of corresponding devices described. The following alternative examples may be implemented, in which some steps are performed in a different order than described or not performed at all. In some examples, each step may include additional features not mentioned below, or further steps may be added. In some cases, the first device 505 may be a UE and the second device 510 may be a base station. Alternatively, the first device 505, the second device 510, or both may be a base station, a CPE, a relay device, a router, a repeater, an IAB node, and other similar devices.

[0118] At 515, the first device 505 may identify a metric associated with communication (e.g., associated with a beam) between the first device 505 and the second device 510. In some cases, the metric may be, may include, or may be based on a signal quality associated with communication between the first device 505 and the second device 510 (e.g., SNR, SINR, RSS, RSRP, RSRQ, or other acceptable signal quality metrics) or a thermal or power characteristic of the first device 505 or the second device 510.

[0119] At 520, the first device 505 may determine a change in state of the first device 505 based on a condition associated with the communication between the first device 505 and the second device 510. In some cases, the condition may be based on a change in the metric (e.g., as the first device 505 may have identified at 515). In some cases, the condition may be (or include) a change in the metric exceeding a threshold (e.g., a preconfigured threshold).

[0120] At 525, the first device 505 may adjust one or more operations for one or more sets of antenna elements of the first device 505 based on the change in state of the first device 505 (e.g., as may have been determined at 520). In some cases, the adjustment operation may include increasing or decreasing the number of antenna elements in the one or more sets of antenna elements of the first device 505 that the first device 505 may use to communicate with the second device 510. Additionally or alternatively, the adjustment operation may include changing a QCL configuration associated with the one or more sets of antenna elements of the first device 505.

[0121] At 530 , for example, based on determining the state change at 520 , the first device 505 may transmit a state change request for one or more sets of antenna elements of the second device 510 to the second device 510 , and the second device 510 may receive the state change request from the first device 505 .

[0122] At 535, the second device 510 may perform adjustments for one or more sets of antenna elements of the second device 510, where the adjustments may be based on the state change request (e.g., as the first device 505 may have determined at 520 and indicated to the second device in the state change request at 525). In some cases, performing the adjustments may include, for example, updating a transmit power at the second device 510 for transmitting to the first device 505 based on the state change request. Additionally or alternatively, performing the adjustments may include, for example, updating an MCS for communications between the first device 505 and the second device 510 based on the state change request.

[0123] At 540, the second device 510 may transmit an indication of an adjustment to the one or more sets of antenna elements of the second device 515 to the first device 505, and the first device 505 may receive the indication from the second device 510, wherein, for example, the adjustment may be based on the state change request. In some cases, the indication of the adjustment to the one or more sets of antenna elements of the second device 510 may indicate an updated transmit power at the second device 510 for transmitting to the first device 505 (e.g., as the second device 510 may have performed in the adjustment at 535). Additionally or alternatively, the indication of the adjustment to the one or more sets of antenna elements of the second device 510 may indicate an updated MCS for communications between the first device 505 and the second device 510 (e.g., as the second device 510 may have performed in the adjustment at 535). In some cases, the indication of the adjustment to the one or more sets of antenna elements of the second device may be communicated via a PDCCH or a PUCCH. Additionally or alternatively, the indication of the adjustment of the one or more sets of antenna elements for the second device may be conveyed via DCI, MAC-CE, or RRC signaling.

[0124] At 545 , the first device 505 can communicate with the second device 510 based on the adjustment of the one or more sets of antenna elements for the second device 510 (eg, as the second device 510 may have performed at 535 ).

[0125] Figure 6 A block diagram 600 of a device 605 that supports adjusting communication operations for changes in configuration for QCL and number of antenna elements according to one or more aspects of the present disclosure is shown. The device 605 may be an example of aspects of a UE 115 as described herein. The device 605 may include a receiver 610, a communication manager 615, and a transmitter 620. The device 605 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0126] Receiver 610 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to adjusting communication operations for changes in configuration of QCL and number of antenna elements, etc.). The information may be passed to other components of device 605. Receiver 610 may be a reference Fig. 9 Examples of aspects of the described transceiver 920.
