[0002] This patent application claims the priority of Indian Patent Application No. 202241022290 filed on April 14, 2022 and titled “CLOSED LOOP POWER CONTROL CORRECTION BY SUBBAND” and assigned to the assignee of this patent application. The disclosure of the prior application is considered a part of this patent application and is incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for closed-loop power control using sub-bands. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0024] The various aspects of the disclosure are described more fully below with reference to the accompanying drawings. However, the disclosure can be embodied in many different forms, and should not be construed as being limited to any specific structure or function presented throughout the disclosure. Instead, these aspects are provided so that the disclosure will be thorough and complete, and the protection scope of the disclosure will be fully conveyed to those skilled in the art. It will be appreciated by those skilled in the art that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than the various aspects of the disclosure set forth herein or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0025] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0026] Although aspects may be described herein using terminology generally associated with 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0027] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include a user equipment (UE) 120 or a plurality of UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e). The wireless network 100 may also include one or more network entities, such as a base station 110 (shown as BS110a, BS110b, BS 110c, and BS110d) and / or other network entities. The base station 110 is a network entity that communicates with the UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit receive point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0028] The base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 that has an association with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. In Figure 1 In the example shown, BS 110a may be a macro base station for macrocell 102a, BS 110b may be a pico base station for picocell 102b, and BS 110c may be a femto base station for femtocell 102c. A base station may support one or more (eg, three) cells.

[0029] In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected with each other and / or to one or more other base stations 110 or network entities in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0030] In some aspects, the term "base station" (e.g., base station 110) or "network entity" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station" or "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (RU), a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network entity" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with base station 110). In some aspects, the term "base station" or "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographical location or in different geographical locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network entity" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network entity" may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network entity" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.

[0031] The wireless network 100 may include one or more relay stations. A relay station is a network entity that can receive transmissions of data from an upstream station (e.g., a network entity or UE 120) and transmit transmissions of data to a downstream station (e.g., a UE 120 or a network entity). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the example shown, BS 110d (eg, a relay base station) may communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. Base station 110 that relays communication may be referred to as a relay station, relay base station, relay, or the like.

[0032] The wireless network 100 may be a heterogeneous network having network entities including different types of BSs, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0033] The network controller 130 may be coupled to or in communication with a set of network entities and may provide coordination and control for the network entities. The network controller 130 may communicate with the base station 110 via a backhaul communication link. The network entities may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link.

[0034] UE 120 can be dispersed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate via a wireless medium.

[0035] Some UE 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UE. MTC UE and / or eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor and / or a location tag, which may communicate with a network entity, another device (e.g., a remote device) or some other entity. Some UE 120 may be considered as an Internet of Things (IoT) device and / or may be implemented as a NB-IoT (narrowband IoT) device. Some UE 120 may be considered as client equipment. UE 120 may be included inside a housing that accommodates components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0036] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0037] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using a network entity as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. UE 120 may communicate via Institute of Electrical and Electronics Engineers (IEEE) 802 protocols, Protocol and / or other protocols for personal area network (PAN) to communicate with other UEs, access points, devices with ultra-wideband capabilities or other devices. In such examples, UE 120 can perform scheduling operations, resource selection operations and / or other operations described elsewhere herein as being performed by base station 110.

[0038] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0039] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0040] Considering the above examples, unless otherwise explicitly stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term can be broadly referred to as a frequency that can be lower than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise explicitly stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term can be broadly referred to as a frequency that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or can be within the EHF band. It is expected that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0041] In some aspects, the wireless device may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may divide a frequency band into a plurality of subbands for closed loop power control (CLPC). The communication manager 140 may obtain a transmit power output measurement for each of the plurality of subbands. The communication manager 140 may average the transmit power output measurements for the plurality of subbands to obtain a transmit power output correction as part of the CLPC, and transmit communications based at least in part on the transmit power output correction, wherein the transmit power output correction is applied to the transmit power output of each subband. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0042] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0043] Figure 2 2 is a diagram illustrating an example 200 of a network entity (e.g., base station 110) communicating with UE 120 in a wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0044] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may further process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0045] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the base station 110 and / or other base stations 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0046] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with network entities via the communication unit 294.

[0047] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0048] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to a network entity. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver.

The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (eg, with reference to Figures 4 to 9 ).

[0049] At a network entity (e.g., base station 110), uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., a demodulator component of modem 232 shown as DEMOD), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120.

[0050] As described in more detail elsewhere herein, a controller / processor of a network entity (e.g., controller / processor 240 of base station 110), controller / processor 280 of UE 120, and / or Figure 2 Any other components of may perform one or more techniques associated with using the subband for CLPC. In some aspects, the wireless device described herein is a UE 120, is included in a UE 120, or includes Figure 2 One or more components of the UE 120 shown. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 8 800 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for a network entity and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of a network entity and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or the network entity to perform or direct, for example, Figure 8 The process 800 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0052] Although Figure 2The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0053] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0054] Figure 3 is a diagram illustrating an example of a decomposed base station 300 according to the present disclosure.

[0055] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element or a network equipment (such as a base station, or one or more units (or one or more components) that perform base station functionality can be implemented in an aggregated or decomposed architecture. For example, a BS (such as a Node B, an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) can be implemented as an aggregated base station (also called an independent BS or a monolithic BS) or a decomposed base station.

[0056] The aggregated base station can be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. The decomposed base station can be configured to utilize a protocol stack physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some aspects, the CU can be implemented within a RAN node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed in one or more other RAN nodes. The DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit (e.g., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU)).

[0057] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0058] The decomposed base station 300 architecture may include one or more CUs 310 that may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed base station units (such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via corresponding midhaul links (such as an F1 interface). The DU 330 may communicate with one or more RUs 340 via corresponding fronthaul links. Fronthaul links, midhaul links, and backhaul links may generally be referred to as "communication links." The RU 340 may communicate with a corresponding UE 120 via one or more RF access links. In some aspects, a UE 120 may be served simultaneously by multiple RUs 340. The DU 330 and the RU 340 may also be referred to as "O-RAN DU (O-DU") and "O-RAN RU (O-RU)", respectively. The network entity may include a CU, DU, RU, or any combination of CU, DU, and RU. The network entity may include a decomposed base station or one or more components of a decomposed base station, such as a CU, DU, RU, or any combination of CU, DU, and RU. The network entity may also include one or more of a TRP, a relay station, a passive device, an intelligent reflective surface (IRS), or other components that may provide a network interface or service for a UE, a mobile station, a sensor / actuator, or other wireless device.

[0059] Each of these units (e.g., CU 310, DU 330, RU 340, and near-RT RIC 325, non-RT RIC 315, and SMO framework 305) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) configured to receive or send signals or both to one or more of the other units on a wireless transmission medium.

[0060] In some aspects, CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented as having an interface configured to communicate signals with other control functions hosted by CU 310. CU310 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0061] DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RU 340. In some aspects, DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) depending at least in part on a functional split such as defined by 3GPP. In some aspects, DU 330 may further host one or more low PHY layers. Each layer (or module) may be implemented with an interface that is configured to communicate signals with other layers (and modules) hosted by DU 330 or with control functions hosted by CU 310.

[0062] The lower layer functionality may be implemented by one or more RUs 340. In some deployments, a RU 340 controlled by a DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 340 may be implemented to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable the implementation of the DU 330 and the CU 310 in a cloud-based RAN architecture (such as a vRAN architecture).

[0063] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-cloud) 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some specific implementations, the SMO framework 305 may communicate directly with one or more RUs 340 via the O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305 .

[0064] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or communicate with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0065] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of O1) or via creation of RAN management policies (such as A1 policies).

[0066] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0067] Figure 4 4 is a diagram illustrating an example 400 associated with using subbands for CLPC according to the present disclosure. Figure 4 As shown in FIG. 1 , a wireless device such as UE 410 (eg, UE 120) may use CLPC to control the transmit power output P 输出 , which may be the power of a signal output by a transmitter and amplified by a power amplifier (PA).

[0068] CLPC can involve measuring P 输出 The measure of P 输出 With the expected P 输出 Compare and adjust the impact P 输出 This can include using an analog-to-digital conversion of the voltage at the output of the transmitter. CLPC can correct for any source of variation in P 输出In contrast, open loop power control (OLPC) adjusts the power factor affecting P by using indirect measurements such as run-time temperature measurements. 输出 Other indirect measurements may be associated with design-time characteristics, such as manufacturing-time (rather than run-time) power measurements (e.g., at one or more points in temperature / frequency) or manufacturing process parameter variations.

[0069] As shown by reference numeral 415, UE 410 may transmit a packet using a transmit power. As shown by reference numeral 420, UE 410 may obtain P 输出 This may include measuring P at the hopping frequency over the entire frequency band of the packet. 输出 That is, P can be measured in frequency and time 输出 As shown by reference numeral 425, UE 410 may correct P 输出 This may include P based on measurements 输出 and the expected P 输出 The difference between them is used to increase or decrease the bias or gain of the PA.

[0070] Note that industry standards generally do not allow P to be adjusted while the UE is transmitting. 输出 In a packet-based communication system, the measurements made at packet [N] can be applied to correct the P of packet [N+1] at the earliest. 输出 In a frequency hopping system, packet [N] and packet [N+1] are usually sent on different channels, and different channels may have different P 输出 Errors. Correcting packet [N+1] with errors from packet [N] may result in overcorrection or undercorrection. Depending on the duration of the hopping sequence, the transmitter may return to the channel of packet [N] later, and P 输出 The calibration process is slowed down. Moreover, a large number of measurements will need to be stored in memory for later use. In the case of multiple measurements (intensive use of memory resources) and delayed P 输出 In the case of correction, some signals may be lost (wasted signaling resources and processing resources) or may be stronger than necessary (wasted power).

[0071] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0072] Figure 5 is a diagram illustrating an example 500 of transmit power output measurement according to the present disclosure.

[0073] Example 500 shows P at different frequencies in a frequency band over time.输出 UE 410 may use the frequency band from the first frequency f0 to the last frequency f n-1 frequency hops, where n is the number of frequency hops. 输出 The change in E b The maximum variation in temperature or in transmission frequency from one transmitter section to another can be specified.

[0074] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0075] Figure 6 is a diagram illustrating an example 600 of using subbands for CLPC according to the present disclosure.

[0076] According to various aspects described herein, a wireless device (eg, UE 410) may divide a frequency band into subbands and measure P at each subband. 输出 UE 410 may select the number of subbands such that P 输出 The P frequency is not varied excessively (exceeding a maximum variation threshold) within a sub-band due to the voltage standing wave ratio (VSWR), which is the amount of mismatch between the antenna and the feed line to the antenna. 输出 less time and resources are spent on P 输出 UE 410 can measure the P of the subband. 输出 The average is measured and a method based at least in part on the average P value across the subband is applied. 输出 Correction. 输出 It is corrected by the same amount at each subband, regardless of the frequency of the next transmission.

[0077] In addition, by dividing the frequency band into sub-bands, the representative P of the sub-bands can be remeasured more frequently. 输出 , thus providing 输出 That is, in pseudo-random frequency hopping, the transmitter can visit each frequency band more frequently than each frequency. For example, in a system divided into 10 sub-bands, the transmitter can return to the sub-band 10 times more frequently than returning to a single frequency. Representative P can be obtained more frequently 输出 Measure 10 times.

[0078] Example 600 shows an example of using subbands for CLPC. As shown by reference numeral 605, UE 410 may send a first communication (e.g., a packet). As shown by reference numeral 610, UE 410 may divide a frequency band into subbands. This step may be performed earlier and / or may be performed only once. As shown by reference numeral 615, UE 410 may obtain P for each subband. 输出 Measurements may be made. This may include one measurement per subband. In some aspects, multiple measurements may be made, but the number of measurements per subband will be less than the number of measurements made using frequency hopping without dividing the frequency band into subbands. 输出 The measurements may be stored in memory.

[0079] As indicated by reference numeral 620, UE 410 may 输出 In some aspects, UE 410 may average the measurements for each new P 输出 Measure and find the average value P 输出 The average value P 输出 Can be expressed as P 输出 The error (Pout_error) can be the expected P 输出 (Pout_expected)-mean value P 输出 (Pout_current). Averaging over the frequency subbands limits the channel-to-channel variation in P 输出 The impact of measurement.

[0080] As indicated by reference numeral 625, UE 410 may determine based at least in part on the average value P 输出 To correct the transmit power output. The correction amount (CLPC_Pout_correction) can be the negative of Pout_error (-Pout_error). For each subband, P 输出 can be corrected by the same amount regardless of the frequency of the next transmission. 输出 , then P can be corrected for each frequency 输出 .

[0081] As indicated by reference numeral 630, UE 410 may use the corrected P 输出 To send a second communication (eg, packet).

[0082] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0083] Figure 7 is a diagram illustrating an example 700 of using subbands for CLPC according to the present disclosure.

[0084] Example 700 shows how UE 410 can divide a frequency band into multiple subbands, where P is measured for each subband. 输出 (P 输出 [0] to P 输出

[10] ). Although 11 subbands are shown in example 700, other numbers of subbands may be used. Example 700 also shows how to correct each subband using error correction, which is based on the average value P 输出 and is the same for each subband.UE 410 may apply error correction to each subband by performing frequency hopping to correct each hopping frequency in the subband with error correction.

[0085] By using subbands for CLPC, there is faster convergence for CLPC. By storing the P 输出 Measure, UE 410 also uses P than storing all frequencies separately 输出 Less memory resources. Compared to using the measurement of the previously transmitted channel to correct the next channel, 输出 There is also a small residual error in the correction.

[0086] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.
