[0047] In some examples, the UE may include hardware components (e.g., amplifiers, duplexers, filters, and antennas) that make up the UE's transmission chain. The performance of these hardware components may vary in response to changes in UE operating conditions (e.g., frequency or temperature), and therefore, the UE may use one or more methods to tune its transmission characteristics to account for these changes. As one approach, the UE may pre-configure certain transmission characteristics across different UE operating conditions. However, pre-configuring the UE in this way may introduce latency into the UE's manufacturing process. Alternatively, the UE may implement an in-line algorithm that allows the UE to dynamically adjust transmitter characteristics in the field. However, the UE may use uplink grants to execute the in-line algorithm, during which the UE may be subject to one or more constraints (e.g., power limits), resulting in a delay in the convergence of the in-line algorithm.

[0048] As described herein, a network entity may allocate resources to a UE for uplink response training of hardware components. The network entity may send an grant to the UE indicating the allocation of resources (e.g., time resources, frequency resources, or both) for uplink response training. This signaling may be broadcast signaling (e.g., directed to multiple UEs) or unicast signaling (e.g., directed to a single UE). Furthermore, before receiving the grant, the UE may signal its capability to perform uplink response training, and the network entity may send the grant based on the UE's capability.

[0049] Furthermore, the UE can receive an instruction to perform uplink response training without applying one or more radio frequency requirements (e.g., power limits). Upon receiving the instruction, the UE can perform uplink response training and determine one or more transmission characteristics that can optimize future communications based on this training. Using the method described herein allows the UE to perform hardware component training in real time during actual operating conditions, thereby enabling rapid and accurate determination of transmission characteristics.

[0050] The aspects of this disclosure are first described in the context of a wireless communication system. Additional aspects of this disclosure are described in the context of a process flow. The aspects of this disclosure are further illustrated by means of and reference to apparatus diagrams, system diagrams, and flowcharts relating to resource allocation for uplink training of UE hardware components.

[0051] Figure 1 An example of a wireless communication system 100 supporting resource allocation for uplink training of UE hardware components according to one or more aspects of this disclosure is 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.

[0052] 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, etc. 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).

[0053] 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 1Some 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.

[0054] 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.

[0055] In some examples, network entity 105 may communicate with core network 130, 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 entities 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 entities 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.

[0056] 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, evolved 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 evolved 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 that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140).

[0057] 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)).

[0058] 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) functions 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.

[0059] 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.

[0060] In the context of applying the techniques described herein to a distributed RAN architecture, one or more components of the distributed RAN architecture can be configured to support resource allocation for uplink training of UE hardware components 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 distributed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0061] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some 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.

[0062] 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.

[0063] 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 defined physical layer structure 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 can 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 in conjunction with both frequency division duplex (FDD) component carriers 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, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0064] 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 may 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.

[0065] 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).

[0066] 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.

[0067] 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)).

[0068] 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 (e.g., control resource set (CORESET)) of the physical control channel 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 for 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.

[0069] Network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., using a carrier) to communicate with network entity 105 and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a coverage area 110 or a portion of coverage area 110 (e.g., a sector) in which a logical communication entity operates. Depending on various factors such as the capabilities of network entity 105, the range of such cells may be from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be a building, a subset of buildings, or external space between or overlapping coverage areas 110, or may include buildings, subsets of buildings, or external space between or overlapping coverage areas.

[0070] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and allow unrestricted access to UE 115 that has a service subscription with a network provider supporting the macro cell. In contrast, small cells may be associated with a lower-power network entity 105 (e.g., a lower-power base station 140) and may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UE 115 that has a service subscription with a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a closed subscriber group (CSG), or UE 115 associated with a user in a home or office). Network entity 105 may support one or more cells and may also use one or more component carriers to support communication via one or more cells.

[0071] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0072] 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.

[0073] 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, half-duplex communication can be performed at a reduced peak rate. 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.

[0074] 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 or 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 prioritization of 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.

[0075] 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 performing D2D communication in a group 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, the 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.

[0076] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which 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.

[0077] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band 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).

[0078] Wireless communication system 100 may utilize both 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, 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 an antenna 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 by the transmitting or receiving 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] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or PDCP layer can be IP-based. The RLC layer performs packet segmentation and reassembly for transmission via logical channels. The MAC layer performs priority processing and multiplexing of logical channels to transport channels. The MAC layer can also implement error detection, error correction, or both to support retransmission and improve link efficiency. In the control plane, the RRC layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and network entity 105 or core network 130 supporting user plane data radio bearers. The PHY layer maps transport channels to physical channels.

[0082] As described herein, network entity 105 may allocate resources to UE 115 for uplink response training. UE 115 may receive a first signaling from network entity 105 that allocates a first set of resources for uplink response training of one or more hardware components constituting the radio frequency chain of UE 115. Furthermore, UE 115 may perform uplink response training of one or more hardware components via the first set of resources and based on the first signaling. Additionally, UE 115 may transmit a second signaling to the network entity based on one or more transmission characteristics via a second set of resources, the one or more transmission characteristics being based on the uplink response training. The method described herein can reduce or eliminate latency associated with other methods. For example, the method described herein can reduce latency associated with manufacturing UE 115.

[0083] Figure 2 An example of a wireless communication system 200 supporting resource allocation for uplink training of UE hardware components according to one or more aspects of this disclosure is shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a UE 115 (e.g., UE 115-a, UE 115-b, and UE 115-c), which may be as described in reference... Figure 1 The example of UE 115 described herein. Furthermore, the wireless communication system 200 may include network entity 105-a, which may be as described in reference... Figure 1 An example of the described network entity 105.

[0084] To transmit signaling to other devices (e.g., UE 115 or network entity 105), UE 115 may include a radio frequency (RF) chain. The RF chain can be described as a series of hardware components that allow UE 115 to convert baseband signals into RF signals. Examples of hardware components in the transmit chain may include filters, phase shifters, power amplifiers, duplexers, attenuators, detectors, mixers, etc. In some examples, the performance of the hardware components may also change as the operating conditions of UE 115 change. For example, the power amplifier of UE 115 may operate linearly up to a threshold output power (or transmit power). Therefore, if the output power of UE 115 exceeds the threshold output power, the power amplifier may operate linearly, resulting in RF signal distortion. The performance of the hardware components may also change in response to changes in the operating frequency of UE 115 (e.g., changes in resource blocks used to transmit RF signals) or changes in the operating temperature of UE 115.

[0085] To offset potential negative performance of the RF chain hardware components during certain operating conditions, UE 115 may adjust one or more transmission characteristics. Alternatively, UE 115 may be pre-configured using different transmission characteristics across different operating conditions (e.g., across different operating frequencies or different operating temperatures). For example, during manufacturing, the UE may be characterized in offline mode across different operating conditions using a call box in the factory, and the results (e.g., transmission characteristics for different operating conditions) may be stored in the UE 115's memory (e.g., non-volatile memory). When UE 115 is scheduled to send signaling to another device, UE 115 may read the transmission characteristics corresponding to the UE 115's current operating conditions from memory and send the signaling to the other device based on those transmission characteristics.

[0086] For example, UE 115 may be scheduled to transmit signaling using an output power higher than a threshold output power, and a transmission characteristic corresponding to that output power may be read from memory. In such scenarios, the transmission characteristic may instruct the performance of digital predistortion operations to reduce the negative impacts (e.g., signal distortion) of a power amplifier operating in a non-linear manner. Other examples of transmission characteristics may include transmission characteristics that instruct the UE 115 to limit its output power (such as to reduce the operating temperature of the UE 115) and increase the digital gain of the power amplifier.

[0087] However, this option has some drawbacks. For example, characterizing UE 115 in this way may increase the time UE 115 spends in the factory, which could introduce latency into the overall manufacturing process of UE 115. Furthermore, with technological advancements, the number of operating conditions UE 115 can withstand may change or increase (e.g., the operating frequency of UE 115 may increase). If new operating conditions are added after UE 115 has left the factory, it is impossible to characterize UE 115 across these new operating conditions, and without such characterization, UE 115 may not be able to offset the negative performance of hardware components caused by the new operating conditions.

[0088] As an alternative, UE 115 may utilize online algorithms to offset performance variations in its hardware components during different operating conditions. For example, UE 115 may be scheduled to transmit a signal to another device (e.g., another UE 115 or network entity 105). During transmission, UE 115 may utilize a feedback receiver to capture the transmitted signal at its antenna and compare the transmitted signal with a baseband signal (e.g., by overlapping the transmitted signal with the baseband signal). Furthermore, UE 115 may use this comparison to determine whether any nonlinear impairments have been introduced into the transmitted signal due to the hardware components of UE 115.

[0089] If a nonlinear impairment is detected, UE 115 can run an online algorithm to discover ways to increase or improve the signal quality of subsequent signal transmissions using the current operating conditions (e.g., the operating conditions used for signal transmission). For example, the online algorithm can adjust different combinations of transmission characteristics until the signal quality is improved (or the algorithm converges). To run the online algorithm, UE 115 is allocated an uplink grant (e.g., from network entity 105). However, in some examples, UE 115 must apply one or more frequency requirements (e.g., uplink power control) to the resources allocated in the uplink grant, which may delay the convergence of the algorithm. Furthermore, the operating conditions at UE 115 can change rapidly. If the operating conditions of UE 115 change, the transmission characteristics may no longer be applied to subsequent signal transmissions performed by UE 115 after signal transmission and before the online algorithm converges.

[0090] As described herein, network entity 105 may allocate resources to UE 115 for uplink response training of one or more hardware components of UE 115. In some examples, network entity 105-a may send demand signaling 225 to UE 115-a. Demand signaling 225 may indicate one or more radio frequency (RF) requirements that may restrict one or more actions of UE 115-a during one or more uplink time slots. For example, RF requirements may indicate a threshold uplink power (e.g., uplink power control) that UE 115-a cannot exceed when communicating in one or more uplink time slots. Other examples of RF requirements that may be included in demand signaling 225 may be a threshold signal quality or threshold in-band transmit amount that UE 115-a must meet or exceed when communicating in one or more uplink time slots, or a threshold out-of-band transmit amount that UE 115-a must not exceed when communicating in one or more uplink time slots.

[0091] In some examples, uplink response training may be supported by some UEs 115 (e.g., premium layer devices) and not by others. With this in mind, UE 115 may send capability signaling 230 indicating whether UE 115 supports uplink response training. For example, using uplink training component 210, UE 115-a may send a signal to network entity 105-a instructing it to perform uplink response training (or... Enhanced-UL-Training-r20The capability signaling 230 indicates the ability of UE 115 to perform uplink response training. In addition to UE 115-a, other UEs 115 in the same cell (e.g., UE 115-b and UE 115-c) may also send capability signaling 230 to network entity 105-a. For example, UE 115-b may send capability signaling 230 to network entity 105-a instructing it to perform uplink response training, and UE 115-c may send capability signaling 230 to network entity 105-a instructing it to perform uplink response training when it is unable to do so.

[0092] Additionally, in some examples, UE 115, capable of performing uplink response training, may request resources for performing uplink response training. For example, using uplink training component 210, UE 115-a may send request signaling 235 to network entity 105-a requesting resource allocation for uplink response training. In some examples, UE 115 may send request signaling 235 when one or more triggering conditions are met. For example, UE 115-a may monitor its operating temperature and send request signaling 235 when the operating temperature meets or exceeds a threshold. Other examples of triggering conditions may include any other changes in operating conditions of UE 115 (e.g., changes in operating frequency). In some examples, UE 115 may monitor changes in operating conditions in response to the completion of a first uplink response training, and if a change is detected, UE 115 may send request signaling 235 requesting resource allocation for a second uplink response training.

[0093] Request signaling 235 may be included in UE Assistance Information (UAI), MAC Control Element (MAC-CE), or any other uplink signaling to network entity 105-a. Furthermore, if UE 115 no longer requires resources for uplink response training, UE 115 may transmit a similar signal (e.g., similar to request signaling 235) requesting network entity 105-a to avoid scheduling UE 115 to perform uplink response training.

[0094] In some examples, network entity 105-a may (e.g., in response to request signaling 235) send grant 240 for uplink response training to one or more UEs 115. Network entity 105-a may use unicast signaling (e.g., to a single UE 115) or broadcast signaling (e.g., to multiple UEs 115) to send grant 240. Furthermore, in some examples, network entity 105-a may send grant 240 only to UEs 115 (e.g., UEs 115-a and UE 115-b), whose capability signaling 230 indicates support for uplink response training. UEs 115 whose capability signaling 230 does not indicate support for uplink response training (e.g., UE 115-c) may not be scheduled by network entity 105-a to perform uplink response training via grant 240.

[0095] In one example, grant 240 may indicate dedicated time and frequency resources that one or more UEs 115 can use to perform uplink response training. Alternatively, grant 240 may indicate a periodically recurring time slot or symbol and a specific resource block location within that time slot or symbol that one or more UEs 115 can use to perform uplink response training. In such examples, grant 240 may be included in RRC signaling. Alternatively, grant 240 may indicate a time slot or symbol (e.g., a time resource), and one or more UEs 115 may select a frequency resource (e.g., a resource of interest) within that time slot or symbol for uplink response training.

[0096] Alternatively or additionally, grant 240 may include multiple options for uplink response training resources. For example, grant 240 may include a first set of time and frequency resources and a second set of time and frequency resources different from the first set of time and frequency resources. In such an example, grant 240 may be included in RRC signaling, and network entity 105-a may activate grant 240 as needed by sending an activation signal 245 (e.g., MAC-CE or downlink control information (DCI)) to one or more UEs 115.

[0097] For example, grant 240 may be included in existing signaling between network entity 105-a and one or more UEs 115. For instance, grant 240 may be included in the DCI that schedules uplink communication. In such an example, the DCI may include an indication that grant 240 is used for uplink response training. This indication may be a bit field in the DCI that includes one or more bits (e.g., flags), and the logical value of those bits indicates that grant 240 in the DCI is to be used for uplink response training. This option allows one or more UEs 115 to perform uplink response training using existing signals without requiring dedicated additional resources, which improves the network's spectral efficiency.

[0098] Additionally, an instruction to perform uplink response training using relaxed radio frequency requirements may be included in grant 240 or other signaling. Performing uplink response training using relaxed radio frequency requirements may include performing uplink response training without applying one or more radio frequency requirements indicated in requirement signaling 225 or pre-configured at UE 115. For example, in response to receiving such an instruction, UE 115-a may perform uplink response training without adhering to uplink power control. That is, during uplink response training, UE 115-a may use an output power greater than an output power threshold to transmit signaling. This allows UE 115 to perform uplink response training without performance degradation and with reduced latency.

[0099] However, in some examples, performing uplink response training without restrictions or using relaxed requirements may result in uplink signaling sent from UE 115 during uplink response training being leaked into out-of-band resources, potentially causing interference at other UE 115s. In such cases, network entity 105-a may avoid scheduling other UE 115s (e.g., UE 115s that are not performing uplink response training or are unable to perform uplink response training) during the uplink time slot allocated for uplink response training, or network entity 105-a may schedule other UE 115s during the uplink time slot used for uplink response training while performing decoding with a low MCS best effort.

[0100] Upon receiving grant 240, one or more UEs 115 may perform uplink response training via the resource allocation indicated in grant 240. Uplink response training allows UE 115 to analyze its hardware components 220 during varying operating conditions and determine which transmission characteristics 215 to use to improve signal quality during these varying operating conditions. For example, using uplink training component 210, UE 115-a may transmit uplink signaling based on varying output power and analyze the behavior of the power amplifier. If the power amplifier operates non-linearly at a certain output power, UE 115-a may determine to perform digital predistortion when UE 115-a encounters a specific output power in subsequent uplink transmissions.

[0101] For example, during uplink response training, UE 115-a can monitor the power amplifier's capabilities (e.g., power amplifier gain) based on the operating temperature. If the power amplifier gain drops significantly, UE 115-a can identify the operating temperature and limit the output power of subsequent uplink transmissions, such as keeping the operating temperature below the identified operating temperature. Furthermore, one or more UEs 115 can store the transmission characteristics 215 determined based on the uplink response training in their memory.

[0102] After completing uplink response training, one or more UEs 115 can communicate with network entity 105-a using transmission characteristics 215 determined based on the uplink response training. For example, UE 115-a may receive an uplink grant from network entity 105-a, which schedules UE 115-a to send an uplink signal 250 to network entity 105-a. Upon receiving the uplink grant, UE 115-a may send the uplink signal 250 to network entity 105-a according to one or more of the determined transmission characteristics 215. Using the method described herein allows the UE to perform real-time training of hardware component 220 under practical operating conditions that can improve accuracy. Furthermore, given that this method is performed in conjunction with network entity 105-a, UE 115 can perform training with relaxed requirements, which allows UE 115 to perform a wider range of uplink response training.

[0103] Figure 3 An example of a process flow 300 supporting uplink training of UE hardware components according to one or more aspects of this disclosure is shown. In some examples, process flow 300 may implement or be implemented by aspects of wireless communication system 100 and wireless communication system 200. For example, process flow 300 may be provided by network entity 105-b and UE 115-b (which may be as referenced) Figure 1 and Figure 2 The following examples (UE 115 and network entity 105) are used for implementation. Alternative examples are also possible, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or additional steps may be added.

[0104] At 305, UE 115-b may optionally receive signaling from network entity 105-b, which indicates one or more radio frequency (RF) requirements for UE 115-b. The one or more RF requirements may include a threshold uplink power, a threshold signal quality, a threshold out-of-band transmit amount, a threshold in-band transmit amount, or a combination thereof.

[0105] At 310, UE 115-b may optionally send signaling to network entity 105-b instructing UE 115-b to perform uplink response training on one or more hardware components that make up the radio frequency chain of UE 115-b. Examples of hardware components may include amplifiers, duplexers, antennas, filters, attenuators, detectors, mixers, or combinations thereof.

[0106] At point 315, UE 115-b may optionally send signaling to network entity 105-b requesting resources for uplink response training. In some examples, UE 115-b may send the request based on the fulfillment of triggering conditions. Triggering conditions may include UE 115-b's operating temperature exceeding a threshold, a change in UE 115-b's operating frequency, or a combination thereof.

[0107] At 320, UE 115-b may receive signaling from network entity 105-b allocating a first set of resources for uplink response training. In some examples, UE 115-b may receive resource granting in response to capability signaling or request signaling. Furthermore, the first set of resources may include time resources, frequency resources, or both. Additionally, the signaling allocating the first set of resources may include one or more bits, and the logical value of these bits may indicate that the first set of resources is used for uplink response training.

[0108] Additionally or alternatively, the signaling may also include periodicity associated with the first set of resources. In some examples, periodicity may include multiple time slots or multiple symbols. In addition to the first set of resources, the signaling may also include a second set of resources. In such an example, at 325, UE 115-b may additionally receive signaling that activates the first set of resources (e.g., DCI or MAC-CE) used for uplink response training.

[0109] At 330, UE 115-b may perform uplink response training via the first set of resources. In some examples, UE 115-b may perform uplink response training in response to resource granting. Performing uplink response training may include monitoring performance metrics of UE 115-b's power amplifier while transmitting uplink signaling, and adjusting the transmission characteristics of UE 115-b based on performance metrics. Adjusting transmission characteristics may include performing digital predistortion on subsequent uplink data transmissions based on performance metrics indicating that the power amplifier is operating in a non-linear manner.

[0110] At 335, UE 115-b can transmit uplink data to network entity 105-b based on one or more transmission characteristics determined during uplink response training and via a third set of resources.

For example, data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or optical particles, or any combination thereof.

[0226] The various exemplary blocks and components described herein can be implemented or performed using a general-purpose processor, DSP, ASIC, CPU, FPGA or other programmable logic device, discrete gate or transistor logic unit, discrete hardware component, or any combination thereof, designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in alternative embodiments, a processor may be any processor, controller, microcontroller, or state machine. 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.

[0227] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. When implemented using software executed by a processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including various portions distributed such that the functions are implemented in different physical locations.

[0228] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of computer-readable media. As used herein, disks and optical discs include CDs, laser discs, optical discs, digital multifunction discs (DVDs), floppy disks, and Blu-ray discs. Disks can magnetically reproduce data, and optical discs can optically reproduce data using lasers. Combinations of the above are also included within the scope of computer-readable media. Any function or operation described herein that can be performed by memory can be performed by multiple memories capable of performing the described function or operation individually or jointly.

[0229] As used herein, the word "or" in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") in the claims indicates an inclusive list, such that a list 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".

[0230] 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. Thus, 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.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0231] 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, obtaining, selecting, choosing, building, and other similar actions.

[0232] 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 them. 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 or other subsequent reference numerals.

[0233] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all implementable or within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," and 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.

[0234] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
