Examples of such multiple access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE) systems, LTE-A Advanced (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ 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, each supporting wireless communication of communication devices, which may be referred to as User Equipment (UE).

[0045] In some wireless communication systems, user equipment (UE) can utilize multi-band antenna modules to support multiple frequency sub-bands within the millimeter-wave band (e.g., different bands within frequency range 2 (FR2), such as n260, n257, n258, etc.). However, even when the UE's operating frequency / sub-band changes, the spacing between the antenna elements used in the multi-band antenna module can remain the same. The spacing between the antenna elements (as a function of the wavelength associated with the carrier frequency) can change with the frequency. For example, a multi-band antenna module may include antenna elements spaced apart by a fixed distance. At a first frequency, the distance between the antenna elements can be expressed as… ,in This represents the wavelength at the first frequency. At the second frequency, the distance between the antenna elements can be expressed as... ,in This indicates the wavelength at the second frequency. Such conditions can cause changes in the beam characteristics at different frequencies / subbands transmitted by the multi-band antenna module. For example, when the beam is guided at a larger angle relative to the aiming line direction, element gain attenuation can increase. Such element gain attenuation of the beam can negatively impact UE performance and reduce communication reliability in the affected frequency / subband. Additionally, element gain attenuation may interfere with communication at other frequencies / subbands or with communication transmitted or received in other directions.

[0046] In some examples, wireless communication systems may utilize band-specific power scaling parameters. For instance, a network entity may indicate power scaling parameters for frequencies / subbands dedicated to millimeter-wave bands for communication performed by a multi-band antenna module at the UE. The network entity may schedule the UE (e.g., for uplink transmissions), and the UE may apply the power scaling parameters to transmissions via the scheduled operating frequency / subband. In some examples, the UE may transmit capability information indicating that it supports a multi-band antenna module, and the network entity may indicate band-specific power scaling parameters to the UE based on this capability information. In some cases, the network entity may indicate a modulation and decoding scheme (MCS) for the operating frequency / subband. The UE may use the MCS for transmissions in the operating frequency / subband to mitigate interference.

[0047] By using band-specific power scaling parameters, the UE can support increased communication reliability by transmitting signals with sufficient power. For example, in some cases and at certain frequencies, element gain attenuation may cause network entities to incorrectly receive signals from the UE, or the network entity may be unable to receive signals due to insufficient power. The UE can increase the transmission power of signals used at certain frequencies / bands (such as bands highly affected by element gain attenuation), thereby supporting increased communication reliability between the UE and network entities at those frequencies without reducing power or losing data.

[0048] The aspects of this disclosure are first described in the context of wireless communication systems. The aspects of this disclosure are further described in the context of wireless communication systems, beam characteristic graphs, and process flows. The aspects of this disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to band-specific power control utilizing multi-band antenna modules.

[0049] Figure 1Examples of a wireless communication system 100 supporting band-specific power control of a multi-band antenna module according to one or more aspects of this disclosure are shown. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating under other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0050] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, among other designations. In some examples, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0051] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Some example UE 115s are illustrated herein. The UE 115 described herein can be able to support various types of devices (such as, e.g., ...). Figure 1 It communicates with other UEs (115 or network entity 105) as shown.

[0052] As described herein, nodes of the wireless communication system 100 (which may be referred to as network nodes or wireless nodes) may be network entity 105 (e.g., any network entity described herein), UE 115 (e.g., any UE described herein), network controller, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. Alternatively, a node may be network entity 105. Furthermore, a first node may be configured to communicate with a second or third node. In one aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0053] In some examples, network entity 105 may communicate with core network 130, or these network entities may communicate with each other, or both. For example, network entity 105 may communicate with core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, network entity 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entity 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0054] One or more network entities in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140).

[0055] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across two or more network entities 105 (such as an Integrated Access Backhaul (IAB) network, an Open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 105 may include one or more of the following: a Central Unit (CU) 160, a Distributed Unit (DU) 165, a Radio Unit (RU) 170, a RAN Intelligent Controller (RIC) 175 (e.g., a near-real-time RIC, a non-real-time RIC), a Service Management and Orchestration (SMO) 180 system, or any combination thereof. 170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0056] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can host lower protocol layers, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by the corresponding network entities 105 communicating via such communication links.

[0057] In a wireless communication system (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB node 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of IAB node 104) may be configured to operate according to the techniques described herein.

[0058] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture can be configured to support band-specific power control using multi-band antenna modules as described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0059] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0060] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, network entities 105, and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown.

[0061] UE 115 and network entity 105 can wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" can refer to a set of RF spectrum resources having a physical layer structure defined for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating 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 coordinating carrier operation, user data, or other signaling. Wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU 160, DU 165, RU170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0062] In some examples, such as in carrier aggregation configurations, a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel grating used for discovery by UE 115. A carrier may operate in standalone mode, in which case initial acquisition and connection can be performed by UE 115 via that carrier, or the carrier may operate in non-standalone mode, in which case different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.

[0063] The communication link 125 shown in the wireless communication system 100 may include downlink transmission (e.g., forward link transmission) from network entity 105 to UE 115, uplink transmission (e.g., return link transmission) from UE 115 to network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink communication or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0064] A carrier may be associated with a specific bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one bandwidth in a set of bandwidths for a particular radio access technology (e.g., 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., network entity 105, UE 115, or both) may have a hardware configuration that supports communication using a specific carrier bandwidth, or may be configured to support communication using one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or UE 115 that supports concurrent communication using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0065] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be 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 decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0066] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, of which It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0067] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may (e.g., in the time domain) be divided into subframes, 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 symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0068] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0069] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region of the physical control channel (e.g., a control resource set (CORESET)) can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0070] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 use the same or different radio access technologies to provide coverage for various coverage areas 110.

[0071] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, network entities 105 (e.g., base station 140) can have similar frame timings, and transmissions from different network entities 105 can be approximately time-aligned. For asynchronous operation, network entities 105 can have different frame timings, and in some examples, transmissions from different network entities 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0072] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not involve concurrent transmission and reception). In some examples, a reduced peak rate can be used to perform half-duplex communication. Other power-saving techniques for UE 115s include entering a power-saving deep sleep mode when not engaged in active communication, operating with limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside a carrier.

[0073] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private or group communication and may be supported by one or more services, such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0074] In some examples, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some examples, one or more UE 115s in a group performing D2D communication may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UE 115s in such a group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, a group of UE 115s communicating via D2D communication may support a one-to-many (1:M) system, where each UE 115 transmits to each of the other UE 115s in the group. In some examples, network entity 105 may facilitate the scheduling of resources used for D2D communication. In other examples, D2D communication may be performed between UEs 115 without involving network entity 105.

[0075] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and may include at least one control plane entity (e.g., a Mobility Management Entity (MME), 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), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be delivered through the user plane entity, which provides IP address allocation and other functions. The user plane entity may connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0076] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the region from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer wavelengths in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0077] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region (also known as the centimeter band) in the range of 3 GHz to 30 GHz or in the extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as the millimeter band) using the spectrum. In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and network entity 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices can be smaller and more closely spaced than UHF antennas. In some examples, such techniques facilitate the use of antenna arrays within the device. However, compared to SHF or UHF transmission, EHF transmission may experience even greater attenuation and a shorter range. The techniques disclosed herein can be adopted for transmission across one or more different frequency regions, and the frequency band usage specified across these frequency regions may vary by country or regulatory authority.

[0078] Wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may use unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology. When operating with unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed frequency bands may be combined with component carriers operating with licensed frequency bands based on carrier aggregation configurations (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0079] Network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation 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 network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0080] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide a beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0081] Network entity 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by network entity 105 in different directions. For example, network entity 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmission along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105) or by a receiving device (such as UE 115)) the beam direction for later transmission or reception by network entity 105.

[0082] Some signals (such as data signals associated with a specific receiving device) may be transmitted by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., the direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted along one or more beam directions. For example, UE 115 may receive one or more signals transmitted by network entity 105 in different directions and may report to network entity 105 an indication of signals received by UE 115 with the highest signal quality or other acceptable signal quality.

[0083] In some examples, transmissions performed by a device (e.g., network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital pre-decoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating pre-decoding weights for one or more beam directions, and this feedback may correspond to a beam set configured across the system bandwidth or one or more sub-bands. Network entity 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may or may not be pre-decoded. UE 115 may provide feedback for beam selection, which may be a pre-decoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel codebook, linear combination codebook, port selection codebook). Although these techniques are described with reference to signals transmitted by network entity 105 (e.g., base station 140, RU 170) in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify the beam direction used by UE 115 for subsequent transmission or reception), or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0084] A receiving device (e.g., UE 115) may perform reception operations according to 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 a transmitting device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple reception directions by: receiving via different antenna subarrays; processing the received signal according to different antenna subarrays; receiving according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets); or processing the received signal according to different sets of reception beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these operations 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 a data signal is received). A single receiver configuration can be aligned along a beam direction determined based on listening according to different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0085] UE 115 and network entity 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data via communication links (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support same-slot HARQ feedback, in which case the device can provide HARQ feedback in a specific time slot for data received via a previous symbol in that time slot. In some other examples, the device may provide HARQ feedback in subsequent time slots or according to a different time interval.

[0086] In some examples, UE 115 may receive (e.g., from network entity 105) a control message indicating power scaling parameters for a frequency sub-band dedicated to the frequency band for wireless communication via an antenna panel at UE 115. In some cases, UE 115 may switch from a second frequency sub-band of the frequency band to the frequency sub-band based on receiving the control message, and UE 115 may switch from a second power scaling parameter associated with the second frequency sub-band to the power scaling parameter based on the switch to the frequency sub-band. UE 115 may transmit signals via the frequency sub-band at a transmit power based on the power scaling parameter dedicated to the frequency sub-band via the antenna panel.

[0087] Figure 2 An example of a wireless communication system 200 supporting band-specific power control of a multi-band antenna module, according to one or more aspects of this disclosure, is shown. The wireless communication system 200 may implement, or be implemented by, aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a UE 115-a and a network entity 105-a, which may be as described in reference... Figure 1 Examples of the corresponding devices described.

[0088] UE 115-a may send a capability message 205 to network entity 105-a. Capability message 205 may indicate that UE 115-a includes a multi-band antenna module 235. For example, UE 115-a may send capability message 205 indicating that the antenna panel at the UE (e.g., multi-band antenna module 235) supports multiple frequency sub-bands of a frequency band. In some examples, multi-band antenna module 235 may include a low-frequency band component 220, a mid-frequency band component 225, and / or a high-frequency band component 230, or any combination of two of these components. The low-frequency band component 220 may support a first frequency range (e.g., 24.25 GHz to 27 GHz), the mid-frequency band component 225 may support a second frequency range greater than the first frequency range (e.g., 27 GHz to 43.5 GHz), and the high-frequency band component 230 may support a third frequency range greater than both the first and second frequency ranges (e.g., 47.2 GHz to 48.2 GHz).

[0089] In some cases, the multi-band antenna module 235 of UE 115-a may support frequency sub-bands in different frequency bands. For example, the multi-band antenna module 235 may support frequency sub-bands in millimeter-wave bands, or may be deployed in millimeter-wave systems. Examples of millimeter-wave bands may include frequency range 2 (FR2), frequency range 4 (FR4), and / or frequency range (5) of radio access technologies, or any combination of these ranges. In some cases, frequency range 1 (FR1) of radio access technologies (e.g., 3GPP radio technologies) may be in the range between 410 MHz and 7125 MHz, FR2 of radio access technologies may be in the range between 24.25 GHz and 71 GHz, FR3 of radio access technologies may be in the range between 7125 MHz and 24.25 GHz, FR4 of radio access technologies may be in the range between 71 GHz and 114.25 GHz, and FR5 of radio access technologies may be in the range between 114.25 GHz and 300 GHz, and higher. In some examples, the multi-band antenna module 235 may support additional frequency sub-bands or frequency ranges outside the millimeter-wave band (such as FR3 or beyond FR5). For the multi-band antenna module 235, the spacing between antenna elements may be the same as the frequency coverage range variation. For example, the spacing between antenna elements may be the same for the low-frequency band component 220, the mid-frequency band component 225, and the high-frequency band component 230.

[0090] UE 115-a can use multi-band antenna module 235 to transmit signals, such as uplink message 215. UE 115-a can transmit uplink message 215 via beamforming transmission (e.g., using an uplink beam). In some examples, the beam characteristics can change significantly with the operating frequency of multi-band antenna module 235. In some phased array antennas, it may be desirable to space the antenna elements relative to the operating frequency of the phased array antenna. However, changing the distance between antenna elements in response to a change in operating frequency may be impractical. Having a separate antenna module for each different possible operating frequency may also be impractical. In such cases, a multi-band antenna module can be configured to communicate within the operating frequency range with a single fixed spacing between antenna elements. Channel properties (e.g., path loss, angular spread) can also change with the operating frequency. Therefore, UE 115-a can change the uplink power control operation (e.g., transmit power) for uplink message 215 based on transmitting messages using the multi-band antenna module 235. The change in uplink power control operation can be band-specific and can be based on the operating frequency of the multi-band antenna module 235.

[0091] UE 115-a may transmit uplink message 215 according to a power control model (e.g., a power control loop). Uplink message 215 may include the Physical Uplink Shared Channel (PUSCH), the Physical Uplink Control Channel (PUCCH), the Sounding Reference Signal (SRS), or a combination thereof. The power control model on the i-th subcarrier may be represented by Equation 1.

[0092]

[0093] In equation 1, The power associated with uplink message 215, and given in dBm. This corresponds to the maximum UE power of UE 115-a. This can correspond to the number of RBs. This corresponds to the target base station received (Rx) power of network entity 105-a. This can correspond to path loss. This can correspond to the transmission format used for uplink message 215 (e.g., MCS), and This can correspond to closed-loop power control values ​​(e.g., power scaling parameters).

[0094] Based on the power control model, the power associated with uplink message 215 (e.g., The power control can be based on the operating frequency of the multi-band antenna module 235. For example, path loss can include propagation loss due to beamforming and array gain. Propagation loss can be a function of the carrier frequency. Assuming a line-of-sight (LOS) condition where the path loss exponent (PLE) is 2, the power required for reliable 71 GHz transmission can be 1.9 dB less than that required for 57 GHz transmission (e.g., due to higher propagation loss at 71 GHz). For a PLE of 3, the power difference can be 2.9 dB. Based on the multi-band antenna module 235 with fixed spacing between antenna elements, the array gain can also be a function of the carrier frequency. Parameters in the power control model It can be an optimization parameter between 0 and 1. It can be set to low for high interference settings, or It can be set to high to compensate for path loss.

[0095] In some examples, network entity 105-a may indicate changes to the uplink power control operation for UE 115-a via control message 210. Based on changes to beam characteristics (e.g., which network entity 105-a can observe or determine), control message 210 may include feedback on band-specific power control parameters. For example, UE 115-a may receive control message 210 indicating power scaling parameters (e.g., ...) for a frequency sub-band (e.g., n257) dedicated to a specific band (e.g., millimeter wave band). UE 115-a can transmit the uplink message 215 via the frequency subband at transmit power through the multi-band antenna module 235, and the transmit power can be based on the power scaling parameter dedicated to the frequency subband.

[0096] Figure 3A and Figure 3B Examples of beam characteristic curves 300 and 305 supporting band-specific power control of a multi-band antenna module according to one or more aspects of this disclosure are shown. Beam characteristic curves 300 and 305 may implement, or be implemented by, aspects of wireless communication system 100 or wireless communication system 200. For example, beam characteristic curves 300 and 305 may illustrate the beam characteristics of uplink message 215 transmitted by UE 115-a, as shown in reference... Figure 2 As described.

[0097] In some examples, the element gain may drift or attenuate relative to the aiming line direction of the antenna array (e.g., in a multi-band antenna module). The model for the attenuation of the element gain can be... , in dB, where This is the angle of deviation from the aiming line. For Beam scanning (e.g., The element gain attenuation can be 2.25 dB, and for Beam scanning (e.g., The element gain attenuation can be 4.5 dB. The model used for element gain attenuation can assume that the spacing d between antenna elements is proportional to the operating frequency. For example, in some designs, d can be approximated as... ,in This refers to the wavelength associated with the operating frequency. The relationship between frequency and wavelength is... ,in At the speed of light, For frequency, and The wavelength is denoted by d. However, for multi-band antenna modules, the operating frequency may change, but due to the construction of multi-band antenna modules, the spacing between antenna elements may be fixed. That is, d can be the same at any operating frequency. However, as The function The size can change with the frequency of operation because of the distance. It is physically fixed.

[0098] In some cases, as the ratio between the wavelength and the spacing between antenna elements approaches one (1) (e.g., The antenna may become more directional. In such cases, peak gain can be increased, gain attenuation of elements deviating from the line of sight can be increased, and radiated energy can be maintained at the same level as... The same applies to the situation. Because the spacing between antenna elements is the same across the operating frequency (e.g., with...). Conversely, variations in peak gain and element gain attenuation off-target direction can affect uplink power control operations performed by UE 115 using the multi-band antenna module.

[0099] Beam characteristics plot 300 illustrates the element gain in dB for an operating frequency of 43 GHz and an antenna element spacing of approximately 5.6 mm, resulting in a gain of 0.81 as a function of wavelength. The spacing between antenna elements. The main lobe 310-a can correspond to the direction pointing towards the aiming line. The beam of the antenna element is directed in the direction of the aiming line, and the main lobe 310-b may correspond to the direction of the aiming line (e.g., The beam of the antenna element. The angle of deviation from the aiming line, the element gain Y1 can be Δ320-a smaller than the element gain Y2 (e.g., peak gain). Δ320-a can correspond to an angle caused by the antenna element pointing towards the line of sight (e.g., The element gain attenuation caused by this.

[0100] In some examples, reducing the spacing between antenna elements can improve element gain when the beam is scanned off-line. Beam properties graph 305 illustrates element gain in dB for an operating frequency of 36 GHz and an antenna element spacing of approximately 5.6 mm, resulting in a gain of 0.67 as a function of wavelength. The spacing between antenna elements. The main lobe 310-c can correspond to the direction pointing towards the aiming line. The beam of the antenna element is directed in the direction of the aiming line, and the main lobe 310-d can correspond to the direction pointing towards the aiming line (e.g., The beam of the antenna element. The angle of deviation from the aiming line, the elemental gain Y3 of the main lobe 310-c can be Δ320-b smaller than the elemental gain Y4 (e.g., peak gain). Δ320-b can correspond to the direction of the antenna element pointing towards the aiming line. The element gain attenuation caused by the angle.

[0101] However, compared to 0.67 The spacing between antenna elements, corresponding to Δ320-b, can be less than 0.81. The spacing between antenna elements corresponds to Δ320-a. In other words, by reducing the spacing between antenna elements... The elemental gain during beam scanning can increase the amount by which the difference between Δ320-a and Δ320-b is increased (e.g., (2.5dB), and element gain attenuation can be reduced. However, multi-band antenna modules can have uniform spacing between antenna elements across the operating frequency, and UE 115 using multi-band antenna modules may not be able to reduce element gain attenuation by reducing the spacing between antenna elements.

[0102] When UE 115 operates across different frequency bands, channel properties may change. For example, path loss (which can be approximated as...) Angular velocity, cluster gain, or other channel properties can change with the operating frequency. UE 115 can implement band-specific power control techniques to mitigate the effects of changes in channel properties across operating frequencies (e.g., due to changes in the relationship between antenna spacing and the wavelength of the operating frequency). However, in addition to changes in channel properties, element gain attenuation can also change when UE 115 operates across different frequency bands, and this attenuation can affect the uplink power that UE 115 can generate. For example, when the UE switches operation from 36 GHz to 43 GHz, the element spacing can remain the same, but the gain attenuation relative to the operating frequency will change. The component spacing ratio can be from 0.81 (As illustrated in beam property curve 300) changed to 0.67 (As illustrated in beam property curve 305). Therefore, for Deviating from the direction of the aiming line (e.g., A beam of light, which can exist equal to the difference between Δ320-a and Δ320-b (for example, , 2.5dB) of elemental gain attenuation.

[0103] In some cases, the link budget of UE 115 may not be saturated. That is, UE 115 can transmit signals, but the power used for signaling may not meet or may not exceed the reference limit. Figure 2 A more detailed description of the power control model Alternatively, the power amplifier of UE 115 can operate at saturation power (e.g., threshold power). The following operations are described. In such cases, UE 115 can compensate for element gain attenuation by changing band-specific power control parameters, thereby increasing the transmit power used for the signal. For example, UE 115 can transmit signals via a frequency subband (e.g., the operating frequency) at transmit power based on a power scaling parameter, which can be dedicated to the frequency subband, through an antenna panel (e.g., a multi-band antenna module). The power scaling parameter may differ from the power control parameters previously configured for UE 115. UE 115 can switch from a second power scaling parameter to the power scaling parameter based on switching from a second frequency subband to that frequency subband. For example, if the UE switches operation from 36 GHz to 43 GHz, the UE can switch from using a first power scaling factor associated with 320-b to using a second power scaling factor associated with 320-a.

[0104] In some examples, UE 115 may use a multi-band antenna module to transmit signals at high frequencies, and the transmitted signals may induce grating lobes, which can cause interference. For example, the transmitted signal illustrated by beam property diagram 300 may include a main lobe 310-a and may also include grating lobes 315-a. Similarly, the main lobe 310-c of beam property diagram 300 may correspond to grating lobe 315-b. UE 115 may limit the scanning range at certain high frequencies (e.g., a threshold angle relative to the aiming line direction) to avoid grating lobes.

[0105] In some cases, the dominant cluster in the channel may be in the first direction that triggers grating lobe 315. In such cases, using band-specific power control parameter changes to increase the transmit power for the signal in the first direction may cause interference in the first direction or other directions, potentially affecting network performance, for example, at network entity 105. Therefore, UE 115 may coordinate with network entity 105 regarding band-specific power control parameter changes. For example, UE 115 may receive a control message indicating power scaling parameters for a frequency sub-band (e.g., FR2) dedicated to the band for wireless communication by the antenna panel at UE 115. In some examples, UE 115 may receive a second control message indicating an offset associated with the power scaling parameters.

[0106] Figure 4 An example of a process flow 400 supporting band-specific power control using a multi-band antenna module according to one or more aspects of this disclosure is shown. Process flow 400 may implement, or be implemented by, aspects of wireless communication system 100 or wireless communication system 200. For example, process flow 400 may include UE 115-b and network entity 105-b, which may be as described in reference... Figure 1 and Figure 2 Examples of the corresponding devices and entities described. In the following description of process flow 400, operations between UE 115-b and network entity 105-b may be sent in a different order than the example order shown, or operations performed by UE 115-b and network entity 105-b may be performed in a different order or at different times. Some operations may also be omitted from process flow 400, and other operations may be added to process flow 400.

[0107] At point 405, UE 115-b and network entity 105-b can exchange capability messages. For example, UE 115-b can send a capability message indicating that the antenna panel at UE 115-b supports multiple frequency sub-bands of a frequency band (e.g., FR2, FR3, FR4, and / or FR5). The capability message can indicate that the antenna panel at UE 115-b is a multi-band antenna module or a component of a multi-band antenna module. In some examples, network entity 105-b can send one or more capability messages or one or more responses to capability messages sent by UE 115-b.

[0108] At 410, UE 115-b can receive a control message indicating the power scaling parameters of the frequency subband dedicated to this frequency band (e.g., This allows for wireless communication via the antenna panel at the UE. For example, when indicating the multi-band antenna module capability at UE115-b, network entity 105-b and UE 115-b may coordinate the use of band-specific power control parameters to accommodate changes in channel and beamforming (e.g., path loss, angular spread, cluster gain, element gain attenuation) resulting from communicating with the multi-band antenna module at different operating frequencies. In some cases, the control message may indicate multiple power scaling parameters, each dedicated to a corresponding frequency sub-band of that band. This control message may be an example of an uplink control information (UCI) message or a MAC control element (MAC-CE) message.

[0109] At 415, UE 115-b can switch from the second frequency subband to that frequency subband based on receiving the control message (e.g., perform a band switch). UE 115-b can switch from the second power scaling parameter associated with the second frequency subband to that power scaling parameter based on the switch to that frequency subband. In some examples, UE 115-b can switch based on the closed-loop power control value. To send a signal, and Frequency band switching can be used to adjust or update the frequency subband. For example, the frequency subband can be a higher frequency subband than the second frequency subband, and the power scaling parameter (e.g., This can indicate an increase in the transmission power used to transmit the signal relative to the second power scaling parameter. In other words, This can increase with increasing operating frequency, and vice versa. At 420, UE 115-b can transmit signals via the frequency subband at this transmit power through the antenna panel (e.g., the multi-band antenna module), the transmit power being based on the power scaling parameter dedicated to that frequency subband.

[0110] In some cases, additionally or alternatively, UE 115-b may change one or more other parameters when adjusting power control parameters. For example, UE 115-b may not change the power control parameters as the operating frequency changes (e.g., increases), or may not change the power control parameters in response to performing a band switching. In such cases, or in other cases, the power budget (e.g., based on the MCS used for the lower operating frequency) may be insufficient at the higher operating frequency. In such cases, UE 115-b may indicate a lower MCS (e.g., a lower-order MCS) to be used at the higher frequency. In some examples, UE 115-b may use a lower MCS with the same power control parameters as the lower power at the higher frequency, or UE 115-b may use a lower MCS in addition to band-specific power control parameters for the higher frequency. For example, at 425, UE 115-b may receive a second control message indicating an MCS dedicated to that frequency subband for wireless communication by the antenna panel at the UE. At 430, UE 115-b can transmit a second signal via the frequency subband using the MCS dedicated to that frequency subband through the antenna panel.

[0111] In some cases, due to power control parameters (e.g., The multi-band antenna module at UE115-b may induce grating lobes in some directions, increasing with the operating frequency. Grating lobes can be mitigated via feedback from interference metrics from network entity 105-b. Therefore, power control parameters... Optimization can be achieved by changing the frequency band-specific power control parameters. For example, at 425, UE 115-b may receive a second control message indicating an offset associated with the power scaling parameters. In some cases, the second control message may indicate one or more interference measurements, and UE 115-b may determine the offset. The second control message may include an indication of one or more grating lobes. The one or more grating lobes may be based on transmitting signals via frequency subbands at transmit power.

[0112] At 430, UE 115-b may transmit a signal at a second transmit power based on an offset. In some cases, UE 115-b may determine the second transmit power without indication from network entity 105-b, or network entity 105-b may indicate the second transmit power explicitly (e.g., via a second control message) or implicitly (e.g., based on interference measurements or indication of grating lobes).

In some examples, transmitter 915 and receiver 910 may be co-located in a transceiver, which may include or be coupled to a modem.

[0150] The communication manager 920, receiver 910, transmitter 915, or various combinations thereof, or various components thereof, may be examples of parts for performing various aspects of band-specific power control using a multi-band antenna module as described herein. For example, the communication manager 920, receiver 910, transmitter 915, or various combinations thereof, or components thereof, may be able to perform one or more of the functions described herein.

[0151] In some examples, the communication manager 920, receiver 910, transmitter 915, or various combinations or components thereof may be implemented in hardware (e.g., in communication management circuitry).

[0152] Additionally or alternatively, the communication manager 920, receiver 910, transmitter 915, or various combinations or components thereof may be implemented in code executed by at least one processor (e.g., as communication management software or firmware). If implemented in code executed by at least one processor, the functionality of the communication manager 920, receiver 910, transmitter 915, or various combinations or components thereof may be performed by a general-purpose processor, DSP, CPU, ASIC, FPGA, microcontroller, or any combination of these or other programmable logic devices (e.g., configured as or otherwise individually or jointly to support components for performing the functions described in this disclosure).

[0153] In some examples, the communication manager 920 may be configured to use or otherwise cooperate with the receiver 910, transmitter 915, or both to perform various operations (e.g., receiving, acquiring, monitoring, outputting, transmitting).

In some embodiments, transceiver 1210 may include one or more processors or one or more memory components, or be configured to couple to such processors or memory components, which are operable to perform or support operations based on received or acquired information or signals, or generate information or other signals for transmission or other output, or any combination thereof. In some embodiments, transceiver 1210, or transceiver 1210 and one or more antennas 1215, or transceiver 1210 and one or more antennas 1215 and one or more processors or one or more memory components (e.g., at least one processor 1235, at least one memory 1225, or both), may be included in a chip or chip assembly mounted in device 1205. In some examples, transceiver 1210 may be able to operate to support communication via one or more communication links (e.g., communication link 125, backhaul communication link 120, midhaul communication link 162, and fronthaul communication link 168).

[0175] At least one memory 1225 may include RAM, ROM, or any combination thereof. At least one memory 1225 may store computer-readable, computer-executable code 1230 including instructions that, when executed by one or more of at least one processor 1235, cause device 1205 to perform the various functions described herein. Code 1230 may be stored in a non-transitory computer-readable medium, such as system memory or another type of memory. In some cases, code 1230 may not be directly executable by one of the at least one processor 1235, but may enable a computer (e.g., when compiled and executed) to perform the functions described herein. In some cases, at least one memory 1225 may also include a BIOS, among other things, that controls basic hardware or software operation, such as interaction with peripheral components or devices. In some examples, at least one processor 1235 may include multiple processors, and at least one memory 1225 may include multiple memories. One or more of the multiple processors may be coupled to one or more of the multiple memories, which may be configured individually or collectively to perform the various functions described herein (e.g., as part of a processing system).

[0176] At least one processor 1235 may include intelligent hardware devices (e.g., general-purpose processors, DSPs, ASICs, CPUs, FPGAs, microcontrollers, programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any combination thereof). In some cases, at least one processor 1235 may be configured to operate a memory array using a memory controller. In some other cases, the memory controller may be integrated into one or more of the at least one processor 1235. At least one processor 1235 may be configured to execute computer-readable instructions stored in memory (e.g., one or more memories in at least one memory 1225) to cause device 1205 to perform various functions (e.g., functions or tasks supporting band-specific power control using a multi-band antenna module). For example, device 1205 or components of device 1205 may include at least one processor 1235 and at least one memory 1225 coupled to one or more of the at least one processor 1235, the at least one processor 1235 and the at least one memory 1225 being configured to perform the various functions described herein. At least one processor 1235 may be an example of a cloud computing platform (e.g., one or more physical nodes and supporting software such as an operating system, virtual machine, or container instance) that can (e.g., by executing code 1230) host functions for performing the functions of device 1205. At least one processor 1235 may be any one or more suitable processors capable of executing scripts or instructions of one or more software programs stored in device 1205 (such as within one or more memories of at least one memory 1225). In some implementations, at least one processor 1235 may be a component of a processing system. A processing system generally refers to a system or series of machines or components that receive input and process that input to produce a set of outputs (which may be passed to other systems or components, such as device 1205). For example, the processing system of device 1205 may refer to a system that includes various other components or sub-components of device 1205 (such as at least one processor 1235, transceiver 1210, communication manager 1220, or other components or combinations of components of device 1205). The processing system of device 1205 can interface with other components of device 1205 and can process information (such as inputs or signals) received from other components or output information to other components. For example, the chip or modem of device 1205 may include a processing system and one or more interfaces for outputting information or for acquiring information, or both. The one or more interfaces may be implemented as or otherwise include a first interface configured to output information and a second interface configured to acquire information, or the same interface configured to both output and acquire information, and other specific implementations.In some embodiments, one or more interfaces may refer to an interface between the processing system of the chip or modem and the transmitter, enabling device 1205 to send information output from the chip or modem. Additionally or alternatively, in some embodiments, one or more interfaces may refer to an interface between the processing system of the chip or modem and the receiver, enabling device 1205 to receive information or signal input and for that information to be transmitted to the processing system. Those skilled in the art will readily recognize that a first interface may also receive information or signal input, and a second interface may also output information or signal output.

[0177] In some examples, bus 1240 may support communication at protocol layers of the protocol stack (e.g., within the protocol layer). In some examples, bus 1240 may support communication associated with logical channels of the protocol stack (e.g., between protocol layers of the protocol stack), which may include communication performed within components of device 1205, or communication performed between different components of device 1205 that may be co-located or located in different locations (e.g., where device 1205 may refer to a system in which one or more of communication manager 1220, transceiver 1210, at least one memory 1225, code 1230 and at least one processor 1235 may be located in one component of different components or partitioned between different components).

[0178] In some examples, the communication manager 1220 can manage (e.g., via one or more wired or wireless backhaul links) various aspects of communication with the core network 130. For example, the communication manager 1220 can manage the transfer of data communication with client devices, such as one or more UEs 115. In some examples, the communication manager 1220 can manage communication with other network entities 105 and may include a controller or scheduler for coordinating with other network entities 105 to control communication with UE 115. In some examples, the communication manager 1220 may support an X2 interface within LTE / LTE-A wireless communication network technology to provide communication between network entities 105.

[0179] According to the examples disclosed herein, the communication manager 1220 can support wireless communication at a network entity. For example, the communication manager 1220 can, is configured, or is operable to support components for receiving a capability message indicating a set of multiple frequency sub-bands of a frequency band supported by an antenna panel at the UE. The communication manager 1220 can, is configured, or is operable to support components for transmitting a control message based on receiving the capability message, the control message indicating power scaling parameters for a frequency sub-band dedicated to that frequency band for wireless communication by the antenna panel at the UE. The communication manager 1220 can, is configured, or is operable to support components for receiving a signal from the antenna panel via that frequency sub-band at a transmission power based on the power scaling parameters dedicated to that frequency sub-band.

[0180] By including or configuring a communication manager 1220 according to an example as described herein, device 1205 can support techniques for improved communication reliability and improved inter-device coordination. For example, by using band-specific power scaling parameters, device 1205 can support enhanced coordination between devices by conveying information about the power used to transmit or receive signals. Device 1205 can support improved communication reliability because signals transmitted according to band-specific power scaling parameters are less likely to cause interference or be received incorrectly.

[0181] In some examples, the communication manager 1220 may be configured to use or otherwise coordinate with the transceiver 1210, one or more antennas 1215 (e.g., where applicable), or any combination thereof to perform various operations (e.g., receiving, acquiring, monitoring, outputting, transmitting). Although the communication manager 1220 is illustrated as a separate component, in some examples, one or more functions described with reference to the communication manager 1220 may be supported or performed by the transceiver 1210, one or more processors in at least one processor 1235, one or more memories in at least one memory 1225, code 1230, or any combination thereof (e.g., by a processing system including at least a portion of at least one processor 1235, at least one memory 1225, code 1230, or any combination thereof). For example, code 1230 may include instructions that can be executed by one or more processors of at least one processor 1235 to cause device 1205 to perform various aspects of band-specific power control using a multi-band antenna module as described herein, or at least one processor 1235 and at least one memory 1225 may be otherwise configured to perform or support such operations individually or jointly.

A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors cooperating with a DSP core, or any other such configuration). Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described functions or operations individually or jointly.

[0253] As used herein (including in the claims), the word "or" used in an enumeration of items (e.g., an enumeration of items accompanied by phrases such as "at least one of" or "one or more of") indicates an inclusive enumeration, such that an enumeration of at least one of, for example, A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0254] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Therefore, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.”

[0255] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), identification, and similar actions. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, acquiring, selecting, choosing, creating, and other similar actions.

[0256] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numeral and a second reference numeral to differentiate between similar components. If only the first reference numeral is used in the description, the description can be applied to any of the similar components having the same first reference numeral, regardless of the second reference numeral or other subsequent reference numerals.

[0257] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "used as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.
