[0002] This application claims priority to Provisional Patent Application No. 63 / 074,740, filed September 4, 2020, entitled “Methods for POWER CONTROL IN ULTRA WANDWIDTH BEAMFORMING SYSTEMS,” and U.S. Patent Application No. 17 / 398,912, filed August 10, 2021, entitled “Methods for POWER CONTROL IN ULTRA WANDWIDTH BEAMFORMING SYSTEMS,” the entire contents of which are expressly incorporated herein by reference. Technical Field
[0003] This disclosure generally relates to communication systems, and more specifically to wireless communication including power control in beamforming systems. Background Technology
[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that enable communication with multiple users by sharing available system resources. Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.
[0005] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the city, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Mobile Broadband Evolution program promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements related to latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements in 5G NR technology. These improvements can also be applied to other multiple access technologies and telecommunications standards that adopt these technologies. Summary of the Invention
[0006] The following is a simplified outline of one or more aspects to provide a basic understanding of them. This outline is not a comprehensive overview of all conceived aspects, nor is it intended to identify key or important elements of all aspects, nor to define the scope of any aspect or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as an introduction to the more detailed descriptions that follow.
[0007] In this disclosure, a method, computer-readable medium, and apparatus for wireless communication at a user equipment (UE) are provided.

The apparatus transmits the first PUSCH, the first PUCCH, or the first SRS at a first power based on a first sub-band within a bandwidth portion (BWP).
[0008] In this disclosure, methods, computer-readable media, and apparatus for wireless communication at a base station are provided. The apparatus transmits to a UE at least one power control parameter for one of a first PUSCH, a first PUCCH, or a first SRS in a first sub-band within a BWP.

[0024] The following detailed description, relating to the accompanying drawings, is intended as a description of various configurations and is not intended to represent the only configuration in which the concepts described herein can be practiced. The detailed description includes specific details for the purpose of providing a comprehensive understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in the form of block diagrams to avoid obscuring these concepts.
[0025] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and methods. These apparatuses and methods will be described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0026] For example, an element, or any part of an element, or any combination of elements, can be implemented as a “processing system” including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in a processing system can execute software. Software should be understood broadly to mean instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, processing, functions, etc., whether they are referred to as software, firmware, middleware, microcode, hardware description languages, or others.
[0027] Therefore, in one or more exemplary embodiments, the described functionality can be implemented in hardware, software, or a combination thereof. If implemented in software, these functions can be stored on a computer-readable medium or encoded as one or more instructions or code on a computer-readable medium. A computer-readable medium includes a computer storage medium. The storage medium can be any available medium accessible by a computer. By way of example, and not limitation, such a computer-readable medium can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures accessible by a computer.
[0028] While aspects and implementations have been described in this application by way of example, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, implementations and / or uses may arise via integrated chip implementations and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail / procurement devices, medical devices, artificial intelligence (AI) enabled devices, etc.). While some examples may or may not specifically relate to use cases or applications, a wide variety of applicability to the described innovations may emerge. The scope of implementations can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating the described aspects and features may also include additional components and features required for implementation and practice of the described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors(s), interleavers, adders / summers, etc.). The innovations described herein can be implemented in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user equipment, etc., of different sizes, shapes, and configurations.
[0029] Figure 1 This is a schematic diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a wireless wide area network (WWAN)) includes a base station 102, a user interface unit (UE) 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). The base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells include base stations. Small cells include femtocells, picocells, and microcells.
[0030] In some aspects, UE 104 may include a power control loop component 198 configured to determine the transmit power for PUSCH, PUCCH, and / or SRS. The power control loop component 198 may determine the transmit power at least partially based on one or more channels within a channelized frequency band or based on a first sub-band within the BWP. In one configuration, the power control loop component 198 may be configured to receive at least one power control parameter for transmitting one of a first PUSCH, a first PUCCH, or a first SRS to the base station. In such a configuration, the power control loop component 198 may transmit one of the first PUSCH, the first PUCCH, or the first SRS at a first power based on the first sub-band within the BWP.
[0031] In some aspects, base station 102 / 180 may include a power configuration component 199 configured to send one or more power-related parameters to UE 104 for UE 104 to determine the transmit power. The power-related parameters may include the target base station received power P. O,PUSCH and path loss compensation factor α. In one configuration, the power configuration component 199 can transmit at least one power control parameter for one of a first PUSCH, a first PUCCH, or a first SRS to the UE in a first sub-band within the BWP. In such a configuration, the power configuration component 199 can receive one of a first PUSCH, a first PUCCH, or a first SRS with a first transmit power from a transmit power UE based on the transmit power of the first sub-band within the BWP.
[0032] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can be connected to EPC 160 via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can be connected to core network 190 via a second backhaul link 184. Among other functions, base station 102 can perform one or more of the following functions: user data transmission, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, location, and warning message delivery. Base station 102 can communicate with each other directly or indirectly (e.g., via EPC 160 or core network 190) via third backhaul link 134 (e.g., X2 interface). First backhaul link 132, second backhaul link 184 and third backhaul link 134 can be wired or wireless.
[0033] Base station 102 can communicate wirelessly with UE 104. Each of base stations 102 can provide communication coverage for its respective geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, small cell 102' may have a coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network may also include a Home Evolution Node B (eNB) (HeNB), which can provide services to a restricted group called a Closed Subscriber Group (CSG). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also known as forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. Base station 102 / UE104 may use spectrum with a bandwidth of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) per carrier, each carrier being allocated in carrier aggregation for transmission in each direction up to a total of Yx MHz (x component carriers). Carriers may or may not be adjacent to each other. Carrier allocation may be asymmetrical relative to DL and UL (e.g., more or fewer carriers may be allocated to DL than to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carriers may be referred to as secondary cells (SCells).
[0034] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL WWAN spectrum. D2D communication link 158 can use one or more sidelink channels, such as Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be conducted through various wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.
[0035] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.
[0036] Cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, cell 102' can employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) as that used by Wi-Fi AP 150. Employing NR in unlicensed spectrum can enhance coverage of the access network and / or increase the access network's capabilities.
[0037] The electromagnetic spectrum is often subdivided into various levels, bands, channels, etc., based on frequency / wavelength. In 5G NR, the two initial operating bands have been designated as frequency range names FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). Although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, although FR2 is different from the Extremely High Frequency (EHF) band (30GHz–300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is often (interchangeably) referred to as the “millimeter wave” band in documents and articles.
[0038] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) frequencies. Recent 5G NR research has designated the operating bands of these IF frequencies as the frequency range name FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit the characteristics of FR1 and / or FR2, and thus can effectively extend the features of FR1 and / or FR2 to IF frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been designated as the frequency range names 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 belongs to the EHF band.
[0039] In light of the foregoing, unless otherwise specifically stated, it should be understood that the terms "sub-6GHz" and the like (if used herein) can broadly refer to frequencies that may be less than 6GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that the terms "millimeter wave" and the like (if used herein) can broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or may be within the EHF band.
[0040] Base station 102 (whether it is a small cell 102' or a large-scale (e.g., macro base station)) may include and / or be referred to as an eNB, gNodeB (gNB), or another type of base station. Some base stations (such as gNB 180) may operate in communication with UE 104 at conventional sub-6 GHz spectrum, millimeter wave frequencies, and / or near-millimeter wave frequencies. When gNB 180 operates at millimeter wave or near-millimeter wave frequencies, gNB 180 may be referred to as a millimeter wave base station. Millimeter wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short range. Base station 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.
[0041] Base station 180 may transmit beamforming signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamforming signals from base station 180 in one or more receive directions 182'. UE 104 may also transmit beamforming signals to base station 180 in one or more transmit directions. Base station 180 may receive beamforming signals from UE 104 in one or more receive directions. Base station 180 / UE 104 may perform beamforming training to determine the optimal receive and transmit directions for each of base station 180 / UE 104. The transmit and receive directions of base station 180 may be the same or different. The transmit and receive directions of UE 104 may be the same or different.
[0042] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are delivered through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. The BM-SC 170 provides functions for MBMS user service provisioning and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 can distribute MBMS traffic to base stations 102 belonging to Multicast-Broadcast Single Frequency Network (MBSFN) areas belonging to broadcast-specific services, and can be responsible for session management (start / stop) and collecting billing information related to eMBMS.
[0043] The core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and the core network 190. Typically, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are delivered through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP services 197. IP services 197 may include the Internet, intranets, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming (PSS) services, and / or other IP services.
[0044] Base stations may include and / or be referred to as gNB, Node B, eNB, access point, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), Transmitter Receiver Point (TRP), or some other suitable terminology. Base station 102 provides UE 104 with access to EPC 160 or core network 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some of UE 104 may be referred to as IoT devices (e.g., parking timers, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more companion devices (such as in a device constellation arrangement). One or more of these devices may access the network uniformly and / or individually.
[0045] Figure 2A This is a schematic diagram 200 illustrating an example of the first subframe within a 5G NR frame structure. Figure 2B This is a schematic diagram 230 illustrating an example of a DL channel within a 5G NR subframe. Figure 2C This is a schematic diagram 250 illustrating an example of the second subframe within a 5G NR frame structure. Figure 2D This is a schematic diagram 280 illustrating an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD) or Time Division Duplex (TDD). In FDD, for a specific set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to either DL or UL. In TDD, for a specific set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to both DL and UL. Figure 2A , Figure 2CIn the provided example, it is assumed that the 5G NR frame structure is TDD, where subframe 4 is configured with slot format 28 (primarily DL), where D is DL, U is UL, and F is the flexibility used between DL / UL, and subframe 3 is configured with slot format 1 (all UL). Although subframes 3 and 4 are shown with slot formats 1 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are all DL and all UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The UE configures the slot format via the received Slot Format Indicator (SFI) (dynamically via DL Control Information (DCI) or semi-statically / statically via Radio Resource Control (RRC) signaling). Note that the following description also applies to the TDD 5G NR frame structure.
[0046] Figures 2A-2D The frame structure is illustrated, and aspects of this disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include mini-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each time slot may include 14 symbols, and for extended CP, each time slot may include 12 symbols. Symbols on the DL may be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL may be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and the parameter set (numerology). The parameter set defines the subcarrier spacing (SCS) and effectively defines the symbol length / duration, which is equal to 1 / SCS.
[0047]
[0048] For a standard CP (14 symbols / slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For an extended CP, parameter set 2 allows 4 slots per subframe. Therefore, for a standard CP and parameter set μ, there are 14 symbols / slot and 2... μ One time slot / subframe. Subcarrier spacing can be equal to 2. μ*15kHz, where μ is the parameter set from 0 to 4. Therefore, parameter set μ = 0 has a subcarrier spacing of 15kHz, and parameter set μ = 4 has a subcarrier spacing of 240kHz. Symbol length / duration is inversely proportional to subcarrier spacing. Figures 2A-2D Examples are provided for a standard frequency division multiplexing (CP) with 14 symbols per slot and a parameter set of μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within the set of frames, one or more different bandwidth portions (BWPs) can exist that are frequency divided multiplexed (see [link to example]). Figure 2B Each BWP can have a specific set of parameters and CP (normal or extended).
[0049] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) extending for 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.
[0050] like Figure 2A As shown, some of the reference (pilot) signals (RS) in the RE carry the UE. The RS may include a demodulation RS (DM-RS) for channel estimation at the UE (indicated as R for a particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS). The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).
[0051] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE Groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbols of the RB. A PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in the PDCCH search space (e.g., the common search space, the UE-specific search space) during PDCCH monitoring times on the CORESET, where PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can be located at higher and / or lower frequencies on the channel bandwidth. The Primary Synchronization Signal (PSS) can be within symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identification. The Secondary Synchronization Signal (SSS) can be within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the Physical Layer Cell Identifier Group Number and radio frame timing. Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the number of RBs and the System Frame Number (SFN) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH (such as System Information Block (SIB)), and paging information.
[0052] like Figure 2C As shown, some REs carry DM-RS for channel estimation at the base station (indicated as R for a specific configuration, but other DM-RS configurations are possible). The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the first or second symbol of the PUSCH. The PUCCH DM-RS can be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and the specific PUCCH format used. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be transmitted in the last symbol of the subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the combs. The SRS can be used by the base station for channel quality estimation to implement frequency-dependent scheduling on the UL.
[0053] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power headroom reports (PHR), and / or UCIs.
[0054] Figure 3 This is a block diagram of base station 310 communicating with UE 350 in the access network. In the DL, IP packets from EPC 160 can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Serving Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functions associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), mobility between radio access technologies (RATs), and measurement configuration for UE measurement reporting; PDCP layer functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with the delivery of upper-layer packet data units (PDUs), error correction via ARQ, linking, partitioning, and reassembling of RLC service data units (SDUs), repartitioning of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs on transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and priority of logical channels.
[0055] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection of the transport channel, forward error correction (FEC) decoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols can then be divided into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time-domain OFDM symbol stream. The OFDM stream is spatially pre-decoded to generate multiple spatial streams. Channel estimation from channel estimator 374 can be used to determine the decoding and modulation scheme, as well as for spatial processing. The channel estimation can be derived from a reference signal and / or channel condition feedback transmitted by UE 350. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can modulate a radio frequency (RF) carrier with its respective spatial stream for transmission.
[0056] At UE 350, each receiver 354RX receives signals through its respective antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides this information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, they can be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier are recovered and demodulated by determining the most probable signal constellation points transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. The soft decision is then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359 that implements Layer 3 and Layer 2 functions.
[0057] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection to support HARQ operation using ACK and / or NACK protocols.
[0058] Similar to the functions described in conjunction with DL transmission via base station 310, controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with upper-layer PDU transmission, error correction via ARQ, RLC SDU linking, partitioning and reassembly, RLC data PDU resegmentation, and RLC data PDU reordering; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs on TB, demultiplexing of MAC SDUs from TB, scheduling information reporting, error correction via HARQ, priority processing, and logical channel priority.
[0059] The channel estimate derived by the channel estimator 358 from the reference signal or feedback transmitted by the base station 310 can be used by the TX processor 368 to select an appropriate decoding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354TX. Each transmitter 354TX can use its own spatial stream to modulate an RF carrier for transmission.
[0060] UL transmission is processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318RX receives signals through its respective antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides this information to the RX processor 370.
[0061] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets from the UE 350. IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for error detection to support HARQ operation using ACK and / or NACK protocols.
[0062] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform operations related to... Figure 1 The power control loop assembly 198 relates to this aspect.
[0063] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform operations related to... Figure 1 Aspects related to the power configuration component 199.
[0064] Base stations can operate at mmW or near-mmW frequencies to communicate with the UE, such as within FR2, which includes the band between 24.25 GHz and 52.6 GHz. Similarly, some base stations can also be configured to operate at frequencies exceeding FR2, such as the band between 52.6 GHz and 114.25 GHz. This band range may be referred to as "Frequency Range 4 (FR4)," "Upper Millimeter Wave Band," or "Sub-THz Regime" (hereinafter collectively referred to as "Ultra-Wide Bandwidth Regime").
[0065] To enable communication devices such as base stations and / or UEs to communicate with other communication devices, these devices may include cascades of electronic components, circuits, and / or sub-units (such as amplifiers, filters, phase shifters, mixers, attenuators, and detectors). This cascading of components can be referred to as a radio frequency (RF) chain. When the communication device is operating at an ultra-wide bandwidth level, the components within the RF chain can become expensive, and therefore the number of components included in the RF chain may be limited. For example, for a base station or UE operating at an ultra-wide bandwidth level, beamforming is typically specified where the base station or UE can frequently use phase shifters to adjust the direction of its transmit or receive beams. Since phase shifters supporting high frequencies can be relatively expensive, the base station or UE may contain only a limited set of phase shifters. Additionally, at higher frequencies (e.g., FR2, FR4), beam tilt may be more likely to occur where the beam direction (e.g., angle) may not always point in the same direction when the operating frequency changes. In the case of beam tilt, the antenna pattern (e.g., beam) pointing at frequency f0 and angle θ0 may be at frequency f0+Δf and angle θ0+Δθ instead of θ0. Phase shifters can be used to mitigate or correct beam tilt. However, when the number of phase shifters is limited in an ultra-wideband RF chain, the base station or UE may not have enough phase shifters to correct beam tilt, which can lead to significant losses in beamforming performance. For example, due to beam tilt, the beam of the base station or UE may not point in the correct direction, which can result in a loss of transmission signal-to-noise ratio (SNR).
[0066] In wireless communication, to enable a receiver to receive data from a transmitter, the transmitter can be configured to transmit data with sufficient transmission power. In some examples, the transmitter can use a high-gain amplifier to regulate (e.g., increase or decrease) the transmission power, and the transmitter can dynamically change its output transmission power based on feedback from the receiver. For example, the receiver can measure the power of the signal from the transmitter and can report the measured power to the transmitter or indicate whether the power is too strong or too low. In response to the measured power or indication, the transmitter can dynamically increase or decrease its transmission power. This type of power control mechanism can be called "closed-loop power control."
[0067] Figure 4Communication flow 400 is an example illustrating closed-loop power control according to various aspects of this disclosure. At 406, transmitter 404 (e.g., UE) may transmit a signal (e.g., data) to receiver 402 (e.g., base station). After receiver 402 receives the signal, at 408, receiver 402 may measure the power of the received signal. At 410, receiver 402 may report the measured power (e.g., in dBm) to transmitter 404 and / or send an indication to transmitter 404 indicating that the transmitted signal (e.g., at 406) is too high or too low. At 412, in response to the report or indication regarding the power of the signal, transmitter 404 may readjust or set the transmission power based at least in part on the report or indication. At 414, transmitter 404 may transmit a signal to receiver 402 at the readjusted or set power. The entire process may be repeated to form a closed loop.
[0068] For a transmitter (e.g., a UE) to transmit a PUSCH, the power control loop of the PUSCH can be represented by the following equation:
[0069] P PUSCH (i)=min{P CMAX ,10log 10 (M PUSCH (i))+P O_PUSCH (j)+α(j)·PL+Δ TF (i)+f(i)}[indBm
[0070] This power control loop can also be used to calculate or estimate the transmit power of the PUCCH and SRS. For example, by Figure 5 As shown in the schematic diagram 500, parameter P CMAX This can be associated with the maximum transmit power supported by the transmitter (e.g., the configured maximum power of the UE). Parameter 10log 10 (M PUSCH (i) can be associated with the number of resource blocks to be sent by the transmitter (e.g., the bandwidth allocated to resource blocks for PUSCH). Parameter This can be associated with a reference point for power control at the target received power or at the receiver (e.g., a base station), which can be the rated PUSCH power provided by the upper layer. Parameter Δ TF(i) can be associated with the transmission format of the modulation and decoding scheme (MCS), which the transmitter can use to adjust the power settings based on the assigned modulation and decoding rate to provide an appropriate SINR for the selected modulation and decoding rate. The parameter f(i) can be associated with a closed-loop feedback parameter, which can be provided by the receiver. The parameter α(j)·PL can be associated with path loss, where α(j) can be used to determine how much path loss component to consider. In some examples, the α(j) parameter can also be referred to as the path loss compensation factor. The α(j) parameter can be an optimization parameter ranging from zero (0) to one (1), where one can indicate that all path loss should be taken into account in the equation, zero can indicate that no path loss should be taken into account in the equation, and so on. For example, if the receiver cannot receive anything from the transmitter regardless of the transmit power, α(j) can be set to a lower value (e.g., close to zero) for high interference settings to save transmit power, while if path loss is to be fully compensated, α(j) can be set to a higher value (e.g., close to one). Depending on the implementation or configuration, the value of α(j) can be determined by the transmitter (e.g., UE) or indicated by the receiver (e.g., base station). The path loss parameter α(j)·PL can also be used to capture propagation loss and array gain caused by beamforming, where propagation loss can be a function of carrier frequency, and given the spacing between fixed antenna elements used in the antenna array, array gain can also be a function of carrier frequency. For example, the transmitter and receiver can be in line-of-sight (LOS) conditions, where the transmitter and receiver can see each other directly without any obstructions between them. When the path loss index (PLE) is two (2), the transmitter may experience worse performance (e.g., higher propagation loss) when transmitting data at 71 GHz than when transmitting data at 57 GHz, for example, a difference of about 1.9 dB. In another example, when the PLE is three (3), such as in non-LOS (NLOS) conditions, the difference may increase to about 2.9 dB.
[0071] Frequency bands (such as those within FR2 or FR4) can be channelized by dividing the band into multiple channels (e.g., sub-bands). This allows communication devices to use the bandwidth (e.g., channels) within the band in a more dynamic or flexible manner. Figure 6This is a schematic diagram 600 illustrating examples of band channelization according to various aspects of this disclosure. A frequency band ranging from 57 GHz to 71 GHz can be channelized by dividing the band into seven channels (e.g., CH0 to CH6), where each channel can have a bandwidth of 2 GHz. For example, channel zero (CH0) may include a bandwidth from 57 GHz to 59 GHz, channel three (CH3) may include a bandwidth from 63 GHz to 65 GHz, and channel six (CH6) may include a bandwidth from 69 GHz to 71 GHz, and so on. In some examples, this division or channelization may also be referred to as 2 GHz channelization of the band. Although Figure 6 The example uses a 57GHz to 71GHz band with 2GHz channelization (e.g., bandwidth per channel), but note that this band can have any frequency range (e.g., 52.6GHz to 71GHz, 71GHz to 114.25GHz, etc.), and the bandwidth of the channelization can be customized according to the implementation (e.g., 2.1GHz, 3.5GHz, 5GHz, etc.). Communication devices can also use one or more channelizations, such as using one channelization (e.g., 2GHz) to communicate with a first device and another channelization (e.g., 3GHz) to communicate with a second device and / or the first device. For example, a communication device can use multiple channelizations in a carrier aggregation (CA) framework (e.g., 2X CA, 3X CA, 4X CA, etc.) in a high-performance setup. Additionally, since the bandwidth portion (BWP) can be a contiguous set of physical resource blocks (PRBs) on a given component carrier (e.g., 24 PRBs), where PRBs can be selected from a contiguous subset of common resource blocks of a given set of parameters. Therefore, the PRB within the BWP can fall on one or more channels (e.g., sub-bands) under channelization.
[0072] After a frequency band is channelized, communication devices (e.g., UEs, base stations, etc.) can use one or more channels within that band for communication. For example, a communication device can use one channel (e.g., CH0 or CH3) at a time or multiple channels (e.g., CH1, CH2, and CH3) at a time, where the communication device can dynamically select the channels(s). The communication device can also use one channel to transmit or receive a portion of data within one or more time slots or symbols within a time slot, and can use another channel to transmit or receive another portion of the data. While communication devices can dynamically select channels for communication within a channelized frequency band, radio frequency (RF) filters may not be used to mitigate interference in the band, as signal and interference bandwidths can also be dynamic. Furthermore, lower-quality filters can cause larger out-of-band spikes in the high-frequency band of interest or interference in adjacent bands due to factors such as cost, complexity, power, heat dissipation, and / or area. Therefore, managing in-band and / or out-of-band interference can be an important aspect of communication devices operating in channelized high-frequency bands.
[0073] The aspects presented in this article can enhance the transmit power (e.g., P) of communication equipment (such as UE, Customer Premises Equipment (CPE), relay / sidelink nodes, repeaters, Integrated Access and Backhaul (IAB) nodes, etc.). PUSCH P PUCCH P SRS The calculation or estimation of parameters (e.g., the channel used by the transmitting device for communication). The aspects presented herein enable the transmitting device to adjust one or more parameters of the power control loop, at least in part, based on the channel (e.g., sub-band) used by the transmitting device for communication.
[0074] In one respect, the power control reference point (P) O_PUSCH The power control reference point (P) can be configured to change when the UE is scheduled on different sub-bands / channelizations with different bandwidths (e.g., different propagation losses, array gains, etc.), where different power control loops can be configured for different channels / sub-bands. In some examples, the power control reference point (P) O_PUSCH The power control reference point (PUSCH) can be configured as a function of a sub-band within a BWP, and the number of power control loops maintained by the UE can be configured by the base station. For example, the power control reference point or PUSCH (e.g., P...). O_PUSCH ), PUCCH (e.g., P O_PUCCH ) or SRS (e.g., P O_SRS The target received power parameter can be changed at least in part based on the channel (e.g., sub-band) that the UE is using to transmit PUSCH, PUCCH, or SRS in the channelized band.
[0075] Figure 7This is a schematic diagram 700 illustrating examples of determining the power control reference point of a UE according to various aspects of this disclosure, wherein the power control reference point can be changed when the UE is being scheduled on different sub-bands or channels with different bandwidths. (See also: Regarding...) Figure 6 The frequency band under discussion, from 57 GHz to 71 GHz, can be channelized into seven channels (CH0 to CH6), each with a bandwidth of 2 GHz. If the UE is transmitting PUSCH, the power control reference point (e.g., P...) O_PUSCH The parameter can be configured to change based on the channel the UE uses to transmit the PUSCH. For example, if the UE is transmitting the PUSCH using channel 702 (e.g., 59-61 GHz), then the parameter for calculating the transmit power P... PUSCH P at time P_PUSCH The parameter can use a first value (e.g., 2dBm), and if the UE is transmitting PUSCH using channel 4 706 (e.g., 65-67GHz), then the calculation of the transmit power P... PUSCH P at time O_PUSCH The parameter can use a second value (e.g., 2.5 dBm), etc. Since different channels (e.g., frequency sub-bands) may be subject to different in-band or out-of-band interference (e.g., different propagation losses, array gains, etc.), the power control reference point P is calculated or assigned based on the channel used by the UE. O_PUSCH Parameters can provide the transmit power of the PUSCH (e.g., P...). PUSCH A more accurate estimate of P can be obtained. P can also be pre-configured and / or optimized for each channel. O_PUSCH The values of the parameters, such as those based on channel conditions. In another example, P O_PUSCH The parameters can be (e.g., based on) sub-bands within the BWP. For example, refer to the... Figure 7 BWP 704 may include or use channel four 706, channel five 708, and channel six 710. If the UE is transmitting PUSCH using channel four 706 (e.g., 65-67 GHz) within BWP 704, then for calculating the transmit power P... PUSCH P at time O_PUSCH The parameter can use a first value (e.g., 2.5 dBm), and if the UE is transmitting PUSCH using channel 5 708 (e.g., 67-69 GHz) within BWP 704, then the calculation of the transmit power P... PUSCH P at time O_PUSCH The parameter can use a second value (e.g., 3.2dBm), etc. Although Figure 7 The examples in the text use PUSCH for illustration, but the disclosed techniques can also be applied to calculate the transmit power of PUCCH (e.g., P...). PUCCH ) and SRS transmit power (e.g., PSRS ).
[0076] In another example, different power control loops (e.g., equations for calculating transmit power) can be configured and provided for each channel (e.g., sub-band) within the channelized frequency band. For example, a first power control loop can be provided for channel 1 702, a second power control loop for channel 4 706, a third power control loop for channel 5 708, etc., where each power control loop can include different parameter values. The parameter values of the power control loop for each channel can also be pre-calculated and / or optimized for each channel, such as based on channel conditions and / or UE capabilities. Therefore, the UE can maintain one or more power control loops and can dynamically select the power control loop depending on the channel being used. The number of power control loops to be maintained by the UE and / or the number of power control loops to be used by the UE can also be configured and indicated by the base station.
[0077] On another front, power headroom (PHR) reports can be submitted on a sub-band basis because P... PUSCH This may be a function of sub-bands. The base station can provide a list of sub-bands from which PHR can be reported, or the UE can determine the sub-bands for reporting PHR (e.g., based on RB allocation). For example, a transmitting device (e.g., a UE) can send one or more PHR reports of PUSCH, PUCCH, and / or SRS to a receiving device (e.g., a base station) based at least in part on the channels used by the transmitting device within the channelized band. Power headroom reports can indicate how much transmit power is available (e.g., remaining) for the transmitting device beyond the power currently being used by the transmission. For example, the power headroom for PUSCH can be calculated by subtracting the PUSCH power from the maximum transmit power of the transmitting device (e.g., PUSCH power headroom = P...). MAX -P PUSCH If the obtained power margin is positive, it indicates that the transmitting device has additional power available for transmission; if the obtained power margin is negative, it indicates that the transmitting device can transmit at a power exceeding its maximum permissible value. This is because the transmission power (e.g., P) PUSCH P PUCCH P SRS (etc.) can be calculated based on the channel, and the transmitting device can also send the PHR to the receiving device based on the channel. For example, as by Figure 8As illustrated in schematic diagram 800, at 806, base station 804 can provide UE 802 with a list of channels (e.g., sub-bands) to report PHRs, where the list may include channels zero, four, and five (e.g., CH0, CH4, and CH5). At 808, UE 802 can transmit one or more data using channels zero, five, and six (e.g., CH0, CH5, and CH6). Based on a request from base station 804, at 810, UE can send PHR reports for CH0 and CH5 to base station 804 and can exclude PHR reports for CH6. Alternatively, or additionally, UE can determine the channels to report PHRs, such as based on RB allocation.
[0078] In some examples, certain power levels of the UE can be allowed or configured to reduce the maximum output power based on higher-order modulation and decoding schemes and transmit bandwidth configurations, where the allowed maximum power reduction (MPR) can be specification-based. On the other hand, for ultra-wideband configurations, the MPR can differ for different sub-bands / channelizations. For example, for transmitting devices (e.g., UEs) within certain power levels (e.g., Level 1, Level 2, Level 3, etc.), the transmitting device can be allowed to reduce its maximum output power due to higher-order modulation and / or transmit bandwidth configurations. The MPR for each power level can be predefined and pre-configured for the transmitting device. Table 1 below is an example MPR table for transmitting devices within power levels 1, 2, and 3.
[0079]
[0080] Table 1—Maximum Power Reduction for Power Levels 1, 2, and 3
[0081] In another aspect of this disclosure, for a channelized high-frequency band (e.g., FR4), the value of MPR can be determined at least in part based on the channels within the channelized high-frequency band, wherein the value of MPR can be different for each channel or for each sub-band within the BWP. For example, refer to back Figure 6 A first table (e.g., similar to Table 1) can be defined and used for CH0 (e.g., 57-59 GHz), a second table with one or more parameters different from the first table can be used for CH1 (e.g., 57-61 GHz), and a third table with one or more parameters different from the first and second tables can be used for CH2 (e.g., 61-63 GHz), and so on. Therefore, a transmitting device at power class 1 communicating at CH0 can have different MPR values than when the transmitting device is communicating at CH1 and / or CH2. MPR values can be used by transmitting devices associated with transmitting PUSCH, PUCCH, and / or SRS, etc.
[0082] In another aspect of this disclosure, under power-limited operation, the UE can prioritize which physical (PHY) channels receive power, and the base station can specify reference sub-bands to be used for these PHY channels. In this scenario, one or more RF / analog beamforming decoders can be optimized for the reference sub-band. For example, when the transmitting device (e.g., the UE) is channelizing a high-frequency band (e.g., as per [reference to [reference]]), Figure 6 When operating in an inherently power-constrained mode (e.g., operating on a low battery setting), the transmitting device can prioritize which physical channels (e.g., PUSCH, PUCCH, SRS, etc.) can use power and / or the amount or proportion of power to be used for these physical channels. For example, the UE can prioritize power for transmitting SRS over transmitting PUSCH and PUCCH, allowing the UE to allocate more power to transmitting SRS. The transmitting device can indicate the selected priority to the receiving device (e.g., a base station). In response, the receiving device can specify one or more reference channels (e.g., sub-bands) within the channelized high-frequency band to be used for these physical channels. For example, the UE can indicate to the base station that it prioritizes transmitting SRS and PUSCH over transmitting PUCCH when using power. In response, the base station can schedule a reference sub-band (e.g., CH0 or 57-59 GHz) for the UE to transmit SRS or PUSCH, and the base station can schedule another reference sub-band (e.g., CH2 or 61-63 GHz) for the UE to transmit PUCCH. In other words, the base station can assign communication channels within the channelized frequency band to the UE's physical channels based on the UE's priority indication. Additionally, one or more RF / analog beamforming decoders can be optimized for these reference sub-bands, where the base station and UE can use these decoders to determine which sub-band (e.g., CH0, CH2, etc.) should be used for the UE's physical channels. Therefore, the channels used for transmitting PUSCH, PUCCH, and / or SRS can be dynamically changed by the transmitting and / or receiving devices, at least in part, based on the power priority selected within the channelized frequency band.
[0083] In another aspect of this disclosure, the receiving device (e.g., a base station) can perform power control of the transmitting device (e.g., a UE), such as by adjusting the path loss compensation factor α(j) of the transmitting device, as per [the relevant context]. Figure 5As described, the receiving device can perform power control at least in part based on adjacent channel leakage and / or based on the bandwidth used in the ultra-wideband energy level (e.g., subbands) (such as channels within a channelized high-frequency band). This adjustment can depend on the base station's knowledge of the array gain of frequencies and the frequencies of interest for which it seeks to control interference. This use can be dynamic, resulting in closed-loop operation at the base station. For example, the adjustment of the path loss compensation factor α(j) can be implemented at the base station, and the adjustment operation can be public to the UE. In such an example, when the first UE is communicating in the first channel or subband (e.g., CH1 or 59-61 GHz), the first UE can interfere with the second UE, while when the first UE is communicating in the second channel or subband (e.g., CH4 or 65-67 GHz), the first UE can not interfere with the second UE. Therefore, the base station can observe the difference in interference levels between the two channels (e.g., CH1 and CH4), and the base station can adjust the UE's path loss compensation factor α(j) to address interference for each channel. For example, when the UE is communicating on CH1, the base station can determine not to compensate for path loss and can assign a value close to zero (0) to the path loss compensation factor α(j), such as regarding Figure 5 As described. When the UE is communicating on CH4, the base station can also determine to fully compensate for path loss and can assign a value close to -1 to the path loss compensation factor α(j). Therefore, the parameter α(j) can be dynamically adjusted by the base station in closed-loop power control mode based at least in part on the carrier frequency used by the UE in the ultra-wide bandwidth or at least in part on the channel used by the UE in the channelized high-frequency band. In addition, the base station can also determine the path loss compensation factor α(j) based at least in part on whether the array gain is known for the frequencies of interest for the expected frequency (e.g., the channel) and / or for competing to control interference (e.g., interference at CH0, CH4, etc.). In another example, the path loss compensation factor α(j) can also be determined based on at least one of the sub-bands within the BWP, or based on the hopping sub-band mode of the UE that includes the sub-bands within the BWP.
