Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 929,846, filed on September 6, 2022, entitled “PILOT SYMBOLS HAVING PILOTSIGNALING AND PEAK-TO-AVERAGE-POWER-RATION SIGNALING,” which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for pilot symbols with pilot signaling and peak-to-average power ratio signaling. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, 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 network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[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 support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a 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 to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present 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 present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present 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 present disclosure is intended to cover such devices or methods implemented using other structures, functionality, or structures and functionality in addition to 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.

[0030] 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.

[0031] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various 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).

[0032] 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, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). For another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0033] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 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, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0034] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 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 associated with a femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0035] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a 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 node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic 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 node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations 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 node" may refer to one of the base station functions, but not another base station function. In this way, a single device may include more than one base station.

[0036] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0037] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 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 network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0038] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0039] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. 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, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.

[0040] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses 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.

[0041] 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.

[0042] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 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. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0043] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that 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 a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. Similar naming issues sometimes occur 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).

[0044] 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, so 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.

[0045] In view of the above examples, unless otherwise specifically 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 frequencies that can be lower than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term can be broadly referred to as frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band. It is contemplated 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.

[0046] In some aspects, a receiving device (e.g., UE 120 or network node 110) may include a communication manager 140 or 150. As described in more detail elsewhere herein, the communication manager 140 or 150 may receive a communication including at least one pilot symbol including pilot signaling on a first set of one or more subcarriers and peak-to-average power ratio (PAPR) signaling on a second set of one or more subcarriers; and communicate based at least in part on the pilot signaling. Additionally or alternatively, the communication manager 140 or 150 may perform one or more other operations described herein.

[0047] In some aspects, a transmitting device (e.g., network node 110 or 120) may include a communication manager 150 or 140. As described in more detail elsewhere herein, the communication manager 150 or 140 may transmit a communication including at least one pilot symbol including pilot signaling on a first set of one or more subcarriers and PAPR signaling on a second set of one or more subcarriers; and communicate based at least in part on the pilot signaling. Additionally or alternatively, the communication manager 150 or 140 may perform one or more other operations described herein.

[0048] As indicated above, Figure 1 are provided as examples. Other examples may be found in the Figure 1 The examples described are different.

[0049] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0050] At the network node 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 network node 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 may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation 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-decoding) 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 also process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) 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 set of corresponding antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0051] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 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 a housing.

[0052] 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 the network node 110 via the communication unit 294.

[0053] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more groups of antenna elements, and / or one or more antenna arrays, etc. An antenna panel, an antenna group, a group of antenna elements, and / or an antenna array may include one or more antenna elements (in a single housing or multiple housings), a group of coplanar antenna elements, a group of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components).

[0054] 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 pre-decoded 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 the network node 110. 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 include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 5 to 10 ) any aspects of any of the methods described herein.

[0055] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 5 to 10 ) any aspects of any of the methods described herein.

[0056] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of may perform one or more techniques associated with pilot symbols with pilot signaling and peak-to-average power ratio signaling, as described in more detail elsewhere herein. In some aspects, the transmitting device described herein is a network node 110, included in the network node 110, or includes Figure 2 In some aspects, the transmitting device described herein is a UE 120, included in a UE 120, or includes Figure 2 One or more components of the UE 120 shown.

[0057] In some examples, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of may execute or direct e.g. Figure 7 The process of 700 Figure 8 800 and / or other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 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 network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion and / or interpretation), may cause one or more processors, UE 120 and / or network node 110 to execute or direct, for example, Figure 7 The process 700 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.

[0058] In some aspects, the receiving device includes means for receiving a communication including at least one pilot symbol including pilot signaling on a first set of one or more subcarriers and PAPR signaling on a second set of one or more subcarriers; and / or means for communicating based at least in part on the pilot signaling. In some aspects, the means for the receiving device to perform operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246. In some aspects, the means for the receiving device to perform operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0059] In some aspects, the transmitting device includes means for transmitting a communication including at least one pilot symbol, the at least one pilot symbol including pilot signaling on a first set of one or more subcarriers and PAPR signaling on a second set of one or more subcarriers; and / or means for communicating based at least in part on the pilot signaling. In some aspects, the means for the transmitting device to perform operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246. In some aspects, the means for the transmitting device to perform operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0060] Although Figure 2 The 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 for 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.

[0061] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2The examples described are different.

[0062] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components 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 RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also called an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0063] An aggregated base station (e.g., an aggregated network node) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) can be configured to utilize a protocol stack that is 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 examples, the CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed across one or more other network 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, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0064] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed 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)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0065] Figure 33 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control 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 respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0066] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being 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 one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0067] In some aspects, CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 310. CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, CU 310 may be logically divided 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, CU310 may be implemented to communicate with DU 330 for network control and signaling.

[0068] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partitioning (such as that defined by 3GPP). In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0069] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions based on functional split (e.g., functional split defined by 3GPP) (such as lower layer functional split), such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane communications and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0070] 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) platform 335) 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, non-RT RIC 315, and near-RTRIC 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 implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0071] 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 in communication 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.

[0072] 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 the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0073] As indicated above, Figure 3 are provided as examples. Other examples may be found in the Figure 3 The examples described are different.

[0074] Figure 4 is a diagram illustrating an example 400 of UE subcarrier tone reservation on one or more subcarriers in accordance with the present disclosure. In some networks, a network node may send a downlink transmission with tone reservation on one or more subcarriers on a physical downlink shared channel (PDSCH) based at least in part on a measurement of an uplink signal from the UE, a request from the UE, an indication of the capabilities of the UE, and / or an independent determination by the network node, etc. (e.g., as described herein).

[0075] In some aspects, a UE may be configured to communicate with a network node using a configuration for tone reservation. For example, the configuration may be common to multiple communications (e.g., for configured grants and / or semi-persistent scheduling resources), multiple UEs connected to a network node, beams provided by a network node, cells provided by a network node, etc.

[0076] As shown in example 400, the PDSCH can include one or more reserved subcarriers (e.g., tones) on which no data and / or pilot is transmitted. In some aspects, the subcarriers can be empty (e.g., without any information intended to be transmitted to the UE). Additionally or alternatively, tone reservation can be applied to physical downlink control channel (PDCCH) symbols (e.g., Figure 4 symbols 0 and 1 in the reserved subcarriers). In some aspects, the pilot may include or may be a reference signal. In some aspects, the network node may send a signal configured to improve the PAPR for downlink transmissions on the PDSCH by using tone reservation to forgo sending data and / or pilot on one or more reserved subcarriers. While example 400 provides an example of tone reservation applied to the PDSCH and / or PDCCH, in some aspects (e.g., when the UE applies tone reservation to uplink communications sent to the network node), the tone reservation may be applied to physical uplink shared channel (PUSCH) and / or physical uplink control channel (PUCCH) symbols.

[0077] The use of tone reservation may involve significant overhead, which may reduce overall throughput. For example, in order to enable the UE to identify which subcarriers (e.g., reserved subcarriers) to be dropped, the network node may indicate the frequency locations of the subcarriers to the UE (e.g., using an identifier). These indications may consume communication, network, and power resources (e.g., bits) for the network node to send (e.g., in downlink control information) and for the UE to receive. Additionally or alternatively, the consumption of network resources for the indication may reduce the throughput that can be used for data (e.g., data associated with the PDSCH). In communications that do not use tone reservation, an increase in PAPR may occur, which may reduce communications between the network node and the UE and may negatively affect the efficiency of power amplification at the network node. Based at least in part on the degradation of the communication, the UE and / or the network node may consume power, communication, network, and computing resources to detect and / or correct communication errors associated with the degradation.

[0078] As indicated above, Figure 4 are provided as examples. Other examples may be used in conjunction with Figure 4 The examples described are different.

[0079] In some networks, waveforms used for wireless communications may be selected to compensate for noise within the network. For example, the network may use a time division multiplexing (TDM) waveform, such as a discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) waveform (e.g., on a downlink), to compensate for and / or minimize the effects of phase noise. The network may use a TDM waveform based at least in part on wireless communications using frequency bands such as FR4, FR5, and / or sub-terahertz frequencies.

[0080] In some networks, a DFT-s-OFDM waveform may have similar characteristics to a single carrier waveform (e.g., using TDM), which may allow for reduced PAPR. The reduced PAPR and reduced phase noise associated with a DFT-s-OFDM waveform may improve the performance, power efficiency, and / or coverage of the network.

[0081] The DMRS in DFT-s-OFDM uses the entire symbol based at least in part on the fact that DFT-s-OFDM is a frequency division multiplexed (FDM) waveform (e.g., a waveform with a single carrier). However, if a transmitting device transmits via multiple layers, the transmitting device may consume multiple symbols of DMRS of different layers. For example, a transmission with two layers (e.g., two beams) may require two symbols of DMRS. This may consume more and more network resources for each layer of transmission. In this way, TDM communication with DMRS may have a relatively high overhead.

[0082] In some networks, a transmitting device may use FDM to send multiple DMRS on a single symbol (e.g., using multiple ports). However, this may remove the PAPR reduction benefits of the DFT-s-OFDM and / or FDM waveforms, which may result in increased PAPR and performance degradation.

[0083] In some aspects described herein, a network may configure pilot symbols with pilot signaling on a first set of subcarriers and with PAPR signaling (e.g., tone reservation signaling configured to reduce PAPR) on a second set of subcarriers. In some aspects, the pilot signaling may be associated with a first receiving device, and the pilot symbols may include additional pilot signaling associated with a second receiving device. For example, the pilot symbols may include a first set of subcarriers with pilot signaling (e.g., DMRS) for the first receiving device, a second set of subcarriers with pilot signaling for the second receiving device, and a third set of subcarriers with PAPR signaling. In some aspects, the pilot symbols may include additional sets of pilot signaling for additional receiving devices and / or additional beams and / or ports associated with the same receiving device.

[0084] Based at least in part on providing PAPR signaling on the pilot symbols, the pilot symbols may have reduced PAPR. Additionally or alternatively, the pilot symbols may support FDM of multiple pilot signals while reducing performance degradation of PAPR from FDM.

[0085] In some aspects, the tone reserved subcarriers may be occupied by PAPR reduction signals that are not DMRS signals. The tone reservation algorithm may be insensitive to which subcarrier positions are allocated for PAPR reduction. Additionally or alternatively, the subcarriers allocated by the tone reservation may have relatively low energy compared to the DMRS resources (e.g., resource elements). Depending on the delay spread of the channel, at least in part based on interpolated channel estimates that support distances of 2 to 6 REs, a DMRS pilot is not required for each resource element (RE). In this way, the tone reserved REs can be periodically sent within the DFT-S-OFDM symbol carrying the DMRS signal.

[0086] In some aspects, the network may configure a "dummy" DMRS port on top of the transmitted DMRS port, wherein the dummy DMRS port has PAPR signaling configured to keep the PAPR low. Some networks may have a limited combination of many required DMRS ports that may support pre-calculation and specification of tone reservation signals in the communication protocol.

[0087] Figure 5 is a diagram of an example 500 associated with a pilot symbol having pilot signaling and PAPR signaling according to the present disclosure. Figure 5 As shown, a transmitting device (e.g., network node 110, CU, DU, and / or RU) may communicate with a receiving device (e.g., UE 120). In some aspects, the transmitting device and the receiving device may be part of a wireless network (e.g., wireless network 100). The transmitting device and the receiving device may be in a Figure 5 The illustrated operations are preceded by establishing a wireless connection.In some aspects, the transmitting device and the receiving device may communicate via MIMO communications.

[0088] As shown by reference numeral 505, the transmitting device and the receiving device may exchange configuration information. For example, as shown by reference numeral 505, the transmitting device may send configuration information to the receiving device. In other examples, the receiving device may send configuration information to the transmitting device (e.g., if the receiving device is a network node and / or the transmitting device is a UE, etc.). In some aspects, the receiving device may receive the configuration information via one or more of RRC signaling, one or more medium access control (MAC) control elements (CEs) and / or downlink control information (DCI), etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for the receiving device to select (e.g., known to the receiving device and / or previously indicated by the transmitting device or other network device) and / or explicit configuration information for the receiving device to configure the receiving device, etc.

[0089] In some aspects, the configuration information may indicate that the receiving device is to provide a capability report and / or support an indication of communication via an FDM waveform, via a DFT-s-OFDM waveform, and / or using pilot symbols including pilot signaling and PAPR signaling, etc. In some aspects, the configuration information may indicate a format to be used for signaling of pilot symbols including pilot signaling and PAPR signaling. In some aspects, the configuration information may indicate one or more parameters for using pilot symbols including pilot signaling and PAPR signaling.

[0090] The receiving device may configure itself based at least in part on the configuration information.In some aspects, the receiving device may be configured to perform one or more operations described herein based at least in part on the configuration information.

[0091] As shown in the figure numeral 510, the receiving device may send and the sending device may receive an indication of support for pilot symbols including pilot signaling and PAPR signaling. For example, the indication of support may indicate the number of subcarriers for which the receiving device supports pilot signaling within the pilot symbol. For example, the receiving device may indicate that a minimum number of subcarriers or a minimum ratio of subcarriers is required to carry pilot signaling within the pilot symbol. Additionally or alternatively, the receiving device may indicate that the pilot symbol may include and still be used as multiple ports of pilots for the receiving device (e.g., for pilots with different beams and / or PAPR signaling).

[0092] As shown by reference numeral 515, the receiving device may receive and the sending device may send an indication of the location of the pilot signaling (e.g., the frequency location of the associated subcarriers) and / or a configuration of the pilot signaling. For example, the receiving device may receive an indication of the location of a first set of one or more subcarriers to carry the pilot signaling (e.g., DMRS signaling). The configuration of the pilot signaling may indicate a sequence used in the pilot signaling and / or a power parameter of the pilot signaling, etc.

[0093] As shown by reference numeral 520, the receiving device may receive and the sending device may send an indication of the location of PAPR signaling (e.g., the frequency location of the associated subcarriers) and / or a configuration of PAPR signaling. For example, the receiving device may receive an indication of the location of a second set of one or more subcarriers to carry PAPR signaling. The configuration of pilot signaling may indicate a waveform and / or power parameters of PAPR signaling (e.g., signaling configured to reduce the PAPR of the communication and / or without data or control information or pilot sequences), etc.

[0094] As shown by reference numeral 525, a receiving device may receive and a transmitting device may transmit a communication including at least one pilot symbol having pilot signaling and PAPR signaling. In some aspects, the at least one pilot symbol may include pilot signaling on a first set of one or more subcarriers and PAPR signaling on a second set of one or more subcarriers. In some aspects, the at least one pilot symbol may include additional pilot signaling (e.g., pilot signaling associated with additional receiving devices and / or additional beams for receiving devices) on a third set of one or more subcarriers, etc.

[0095] In some aspects, PAPR signaling may include signaling sent at different power levels at different subcarrier locations of a communication. Signaling may be configured with different power levels at different subcarriers so that when signaling is added to another portion of the communication (e.g., data and / or pilot), the communication power across all subcarriers of the communication may have a reduced variation (e.g., a variation between a peak power level and an average power level). In this manner, based at least in part on inserting PAPR signaling into the communication at a second set of the one or more subcarriers, the communication may have a reduced PAPR. The reduced PAPR may reduce saturation of a power amplifier at a transmitting device, which may improve power efficiency and / or reduce signal clipping. Additionally or alternatively, the reduced PAPR reduces saturation at a receiver, which may improve demodulation of the communication.

[0096] In some aspects, the communication may include FDM communication and / or DFT-s-OFDM communication, etc. For example, the communication may include a single waveform data symbol and a pilot symbol. In some aspects, the pilot symbol may include pilot signaling interleaved with PAPR signaling. In some aspects using multiple pilot signaling (e.g., associated with different ports), the pilot symbol may include subcarriers that are rotated (e.g., in the frequency domain) sequentially through the pilot signaling and PAPR signaling of each port. For example, the pilot symbol may have a subcarrier pattern, and the subcarriers are described from the highest frequency to the lowest frequency in sequence as: port 0 pilot signaling on subcarrier n, port 1 pilot signaling on subcarrier n-1, port 2 pilot signaling on subcarrier n-2, PAPR signaling on subcarrier n-3, port 0 pilot signaling on subcarrier n-4, port 1 pilot signaling on subcarrier n-5, port 2 pilot signaling on subcarrier n-6, PAPR signaling on subcarrier 7, etc.

[0097] As shown in reference numeral 530, the receiving device may decode one or more data symbols based at least in part on the pilot signaling. In some aspects, the receiving device may use the pilot signaling (e.g., DMRS) to perform channel estimation. In some aspects, the receiving device may interpolate between subcarriers of pilot symbols carrying the pilot signaling to estimate a channel associated with the communication. The receiving device may use the channel estimate to attempt to decode the data symbols of the communication.

[0098] As shown by reference numeral 535, the transmitting device and the receiving device may communicate based at least in part on pilot signaling. In some aspects, the transmitting device and the receiving device may communicate using FDM communication and / or DFT-s-OFDM communication, etc. For example, the transmitting device and the receiving device may use communication including a single waveform data symbol and a pilot symbol.

[0099] Based at least in part on providing PAPR signaling on the pilot symbols, the pilot symbols may have reduced PAPR. Additionally or alternatively, the pilot symbols may support FDM of multiple pilot signals while reducing performance degradation of PAPR from FDM. In this way, the transmitting device and the receiving device may save network resources that may have been used to communicate additional pilot symbols for each beam and / or receiving device.

[0100] As indicated above, Figure 5 are provided as examples. Other examples may be used in conjunction with Figure 5 The examples described are different.

[0101] Figure 6 is a diagram of an example 600 associated with a pilot symbol with pilot signaling and PAPR signaling according to the present disclosure. Figure 6In some aspects, the transmitting device (e.g., network node 110, CU, DU, and / or RU) may communicate with a receiving device (e.g., UE 120) using communications including pilot symbols having one or more pilot signaling ports and PAPR signaling ports. In some aspects, the transmitting device and the receiving device may be part of a wireless network (e.g., wireless network 100). The transmitting device and the receiving device may be in a Figure 6 The operations shown are performed after a wireless connection has been established.

[0102] like Figure 6 As shown, the communication may include one or more pilot symbols 605 and one or more sets of data symbols 610. The communication may include multiple pilot symbols based at least in part on channel conditions (e.g., associated with changing channel conditions that may require additional pilot density within the communication). As shown, the communication may include two pilot symbols 605, and this is a non-limiting example. The communication may include a single pilot symbol 605, three pilot symbols, or more pilot symbols.

[0103] The pilot symbols 605 include a first pilot symbol port (P1), a second pilot symbol port (P2), a third pilot symbol port (P3), and PAPR signaling. In some aspects, a communication may include pilot signaling in each of the pilot signal ports or only in a portion of the pilot signal ports. For example, a communication may be configured with multiple pilot signal ports regardless of whether each of the pilot signal ports is in use. Figure 6 As shown, pilot symbols may be interleaved with resources used for pilot signal ports and PAPR signaling.

[0104] In some aspects, the first pilot symbol 605 and the second pilot symbol 605 may include the same set of pilot signal ports and PAPR signaling. In some aspects, the first pilot symbol 605 may include a first set of pilot signal ports, and the second pilot symbol 605 may include a second set of pilot signal ports. In some aspects, PAPR signaling occupies the pilot signal ports as dummy ports. In this way, PAPR signaling may be included on each pilot symbol 605, or may be included on a subset of pilot symbols 605.

[0105] The receiving device may use one or more ports of the pilot signaling to estimate the channel of the communication. The receiving device may use the channel estimate to decode the data symbols 610 by using interpolation and / or extrapolation.
