[0001] The present Application for Patent claims the benefit of Israel Patent Application No. 310809 by GUTMAN et al., entitled “VOLTAGE SWING CONTROL FOR ROBUSTNESS IN WIRELESS COMMUNICATIONS,” filed February 13, 2024, assigned to the assignee hereof, and expressly incorporated by reference herein.FIELD OF TECHNOLOGY
[0002] The following relates to wireless communication, including voltage swing control for robustness in wireless communications.BACKGROUND
[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE).SUMMARY

The receiving device may measure a signal power in accordance with the configuration, and may determine a difference between an expected power level, or threshold signal power level before a signal performance is reduced, and the measured signal power level. This difference may be referred to as an interference power headroom (IPH). The device may transmit an IPH report to the network entity indicating the IPH, and the network entity may use the IPH report to signal recommended adjustments to voltage swing or to adjust a schedule for one or more communications.

[0049] Some wireless communications systems may support full duplex communications. For example, a network entity may transmit downlink communications to one or more devices, including user equipments (UEs) and other network nodes, while receiving uplink communications from other devices at the sametime. However, full duplex communications may introduce additional interference. For example, a victim device receiving in downlink from the network entity may experience interference from an aggressor device transmitting at the same time in uplink. Such interference may increase a power of a signal received at the victim device, reducing a signal-to-noise ratio (SNR) for the received signal and resulting in lower quality communications while increasing a chance of failed decoding. In some cases, the victim device may implement post-processing operations, increased gain of analog-front-end (AFE) circuitry or analog-to-digital converter (ADC), or increased dynamic range of reception and voltage swing to improve a quality of received signaling. However, doing so may result in an increase in power consumption at the device, increased noise, or reduction in a link budget of a network.
[0050] As described herein, a wireless communications system may support dynamic voltage swing control at one or more devices to mitigate interference during full duplex communications. For example, a network entity may output (e.g., transmit wirelessly or output via another medium or device) a measurement configuration for measuring signal power at a receiving device (e.g., a wireless communication device, a UE, a receiving network node) based on a capability of the device. The receiving device may measure a signal power in accordance with the configuration, and may determine a difference between an expected value or threshold signal power level (e.g., defining at which point there is a reduction in signal performance) and the measured value to determine an effect of interference on an original signal. This measured difference (e.g., due to interference, or available headroom) may otherwise be known as an interference power headroom (IPH). The device may transmit an IPH report to the network entity, and the network entity may use the IPH report to signal recommended adjustments to voltage swing or to adjust a schedule for one or more communications.
[0051] In some examples, signaling IPH reports may improve a quality of communications received at a device while also reducing related power consumption. For example, updating a voltage swing based on recommendations, a device with a saturated receive channel may dynamically and temporarily increase voltage to improve communications. For example, a signal-to-noise ratio may be improved while reducing a bit error rate (BER). Further, if a device has available IPH, the device may reduce a voltage swing to save additional power. Scheduling adjustments using IPH reports mayalso increase signal quality by reallocating resources to reduce interference at the saturated devices. Further, signaling voltage swing and other parameter recommendations may allow devices to select whether to increase performance and robustness to interference or blocking entities at the cost of power savings (e.g., increase voltage swing) or vice versa.
[0052] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to signaling diagrams and process flows that relate to voltage swing control for robustness in wireless communications. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to voltage swing control for robustness in wireless communications.
[0053] FIG. 1 shows an example of a wireless communications system 100 that supports voltage swing control for robustness in wireless communications in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE- A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0054] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link). For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which a networkentity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs).
[0055] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1.
[0056] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be anetwork entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0057] In some examples, network entities 105 may communicate with the core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., in accordance with an SI, N2, N3, or other interface protocol). In some examples, network entities 105 may communicate with one another via a backhaul communication link 120 (e.g., in accordance with an X2, Xn, or other interfaceprotocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via a core network 130). In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol), or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link), one or more wireless links (e.g., a radio link, a wireless optical link), among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0058] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).
[0059] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which may be configured to utilize a protocol stack that is physically or logically distributed among two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, a network entity 105 may include one or more of a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN Intelligent Controller (RIC) 175 (e.g., a Near-Real Time RIC (Near-RT RIC), a Non-Real Time RIC (Non-RT RIC)), a Service Management and Orchestration (SMO) 180 system, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU),or a transmission reception point (TRP). One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).
[0060] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control (RRC), service data adaption protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (LI) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or more RUs 170). In some cases, a functional split between a CU 160 and a DU 165, or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170). A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to one or more DUs 165 via a midhaul communication link 162 (e.g., Fl, Fl-c, Fl-u), and a DU 165 may be connected to one or more RUs 170 via a fronthaulcommunication link 168 (e.g., open fronthaul (FH) interface). In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that are in communication via such communication links.
[0061] In wireless communications systems (e.g., wireless communications system 100), infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as a donor entity or an IAB donor. One or more DUs 165 or one or more RUs 170 may be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140). The one or more donor network entities 105 (e.g., IAB donors) may be in communication with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). IAB nodes 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay of communications with UEs 115, or may share the same antennas (e.g., of an RU 170) of an IAB node 104 used for access via the DU 165 of the IAB node 104 (e.g., referred to as virtual IAB-MT (vIAB-MT)). In some examples, the IAB nodes 104 may include DUs 165 that support communication links with additional entities (e.g., IAB nodes 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream). In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of IAB nodes 104) may be configured to operate according to the techniques described herein.
[0062] For instance, an access network (AN) or RAN may include communications between access nodes (e.g., an IAB donor), IAB nodes 104, and one or more UEs 115. The IAB donor may facilitate connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, an IAB donor may refer to a RAN node with a wired or wireless connection to core netw ork 130. TheIAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). IAB donor and IAB nodes 104 may communicate via an Fl interface according to a protocol that defines signaling messages (e.g., an Fl AP protocol). Additionally, or alternatively, the CU 160 may communicate with the core network via an interface, which may be an example of a portion of backhaul link, and may communicate with other CUs 160 (e.g., a CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of a portion of a backhaul link.
[0063] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UEs 115, wireless self-backhauling capabilities). A DU 165 may act as a distributed scheduling node towards child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards parent nodes associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node in communication with one or more child nodes (e.g., an IAB donor may relay transmissions for UEs through one or more other IAB nodes 104). Additionally, or alternatively, an IAB node 104 may also be referred to as a parent node or a child node to other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of IAB nodes 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and the DU interface (e.g., DUs 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or UE 115.
[0064] For example, IAB node 104 may be referred to as a parent node that supports communications for a child IAB node, or referred to as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 with a wired or wireless connection (e.g., a backhaul communication link 120) to the core network 130 and may act as parent node to IAB nodes 104. For example, the DU 165 of IAB donor may relay transmissions to UEs 115 through IAB nodes 104, or may directly signal transmissions to a UE 115, or both. The CU 160 of IAB donor may signal communication link establishment via an Fl interface to IAB nodes 104, and the IAB nodes 104 may schedule transmissions (e.g., transmissions to the UEs 115 relayed from the IAB donor) through the DUs 165. That is, data may be relayed to and from IAB nodes 104 via signaling via an NR Uu interface to MT of the IAB node 104.Communications with IAB node 104 may be scheduled by a DU 165 of IAB donor and communications with IAB node 104 may be scheduled by DU 165 of IAB node 104.
[0065] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support voltage swing control for robustness in wireless communications as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175, SMO 180).
[0066] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (loT) device, an Internet of Everything (loE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, or vehicles, meters, among other examples.
[0067] The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.[006S] The UEs 115 and the network entities 105 may wirelessly communicate with one another via one or more communication links 125 (e.g., an access link) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for a communication link 125 may include a portion of a RF spectrum band (e.g., a bandwidth part (BWP)) that isoperated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, subentity) of a network entity 105. For example, the terms “transmitting,” “receiving,” or “communicating,” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).
[0069] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN)) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different radio access technology).
[0070] The communication links 125 shown in the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDDmode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode).
[0071] A carrier may be associated with a particular bandwidth of the RF spectrum and, in some examples, the carrier bandwidth may be referred to as a “system bandwidth” of the carrier or the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0072] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam), and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0073] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a samplingperiod of Ts=seconds, for which fnaxmay represent a supported subcarrier spacing, and N may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).
[0074] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period). In some wireless communications systems 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N ) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0075] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).
[0076] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 maymonitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to multiple UEs 115 and UE-specific search space sets for sending control information to a specific UE 115.
[0077] A network entity 105 may provide communication coverage via one or more cells, for example a macro cell, a small cell, a hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used for communication with a network entity 105 (e.g., using a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or others). In some examples, a cell also may refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) over which the logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of structure) to larger areas depending on various factors such as the capabilities of the network entity 105. For example, a cell may be or include a building, a subset of a building, or exterior spaces between or overlapping with coverage areas 110, among other examples.
[0078] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, the overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.
[0079] Some UEs 115, such as MTC or loT devices, may be low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network entity 105 (e.g., a base station 140) without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.
[0080] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently). In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs)) within a carrier, within a guard-band of a carrier, or outside of a carrier.
[0081] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC). The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and maybe supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0082] In some examples, a UE 115 may be configured to support communicating directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., in accordance with a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of anetwork entity 105 (e.g., a base station 140, an RU 170), which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1:M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity7105.
[0083] In some systems, a D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UEs 115). In some examples, vehicles may communicate using vehicle-to- everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these. A vehicle may signal information related to traffic conditions, signal scheduling, weather, safety , emergencies, or any other information relevant to a V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or with the network via one or more network nodes (e.g., network entities 105, base stations 140, RUs 170) using vehicle-to- network (V2N) communications, or with both.
[0084] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility7functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet(s), an IP Multimedia Subsystem (IMS), or a Packet-Switched Streaming Service.
[0085] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0086] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carriersensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA). Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0087] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0088] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), for which multiple spatial layers are transmitted to the same receivingdevice, and multiple-user MIMO (MU-MIMO), for which multiple spatial layers are transmited to multiple devices.
[0089] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., anetwork entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmiting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmiting device or receiving device, or with respect to some other orientation).
[0090] A network entity 105 or a UE 115 may use beam sweeping techniques as part of beamforming operations. For example, a network entity 105 (e.g., a base station 140, an RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to conduct beamforming operations for directional communications with a UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmited by a network entity' 105 multiple times along different directions. For example, the network entity 105 may transmit a signal according to different beamforming weight sets associated with different directions of transmission. Transmissions along different beam directions may be used to identify (e.g., by a transmiting device, such as a netw ork entity 105, or by a receiving device, such as a UE 115) a beam direction for later transmission or reception by the netw ork entity 105.
[0091] Some signals, such as data signals associated with a particular receiving device, may be transmited by transmiting device (e.g., a transmitting network entity 105, a transmiting UE 115) along a single beam direction (e.g., a direction associatedwith the receiving device, such as a receiving network entity 105 or a receiving UE 115). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on a signal that was transmitted along one or more beam directions. For example, a UE 115 may receive one or more of the signals transmitted by the network entity 105 along different directions and may report to the network entity 105 an indication of the signal that the UE 115 received with a highest signal quality or an otherwise acceptable signal quality.
[0092] In some examples, transmissions by a device (e.g., by a network entity 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from a network entity 105 to a UE 115). The UE 115 may report feedback that indicates precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more sub-bands. The network entity 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI- RS)), which may be precoded or unprecoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted along one or more directions by a network entity 105 (e.g., a base station 140, an RU 170), a UE 115 may employ similar techniques for transmitting signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal along a single direction (e.g., for transmitting data to a receiving device).
[0093] A receiving device (e.g., a UE 115) may perform reception operations in accordance with multiple receive configurations (e.g., directional listening) when receiving various signals from a transmitting device (e.g., a network entity 105), such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may perform reception in accordance with multiple receive directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weightsets) applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, a receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have a highest signal strength, highest SNR, or otherwise acceptable signal quality based on listening according to multiple beam directions).
[0094] The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network entity 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0095] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., a communication link 125, a D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previoussymbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
[0096] The wireless communications system 100 may also support dynamic voltage swing control at one or more devices to mitigate interference during full duplex communications. For example, a network entity 105 may output a measurement configuration to a wireless communication device, such as a UE 115 or other network entity 105 (e.g., another network node), for measuring signal power based on a capability report transmitted by the device. The device may measure an IPH among other values using the parameters of the measurement configuration, and may transmit an IPH report to the network entity 105. The network entity 105 may use the IPH report to signal recommended adjustments to voltage swing or to adjust a schedule for one or more communications for one or more devices for increased power savings and improved quality in communications.
[0097] FIG. 2 shows an example of a network architecture 200 (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that supports voltage swing control for robustness in wireless communications in accordance with one or more aspects of the present disclosure. The network architecture 200 may illustrate an example for implementing one or more aspects of the wireless communications system 100. The network architecture 200 may include one or more CUs 160-a that may communicate directly with a core network 130-a via a backhaul communication link 120-a, or indirectly with the core network 130-a through one or more disaggregated network entities 105 (e.g., aNear-RT RIC 175-b via an E2 link, or a Non-RT RIC 175-a associated with an SMO 180-a (e.g., an SMO Framework), or both). A CU 160-a may communicate with one or more DUs 165-a via respective midhaul communication links 162-a (e.g., an Fl interface). The DUs 165-a may communicate with one or more RUs 170-a via respective fronthaul communication links 168-a. The RUs 170-a may be associated with respective coverage areas 110-a and may communicate with UEs 115-a via one or more communication links 125-a. In some implementations, a UE 115-a may be simultaneously served by multiple RUs 170-a.
[0098] Each of the network entities 105 of the network architecture 200 (e.g., CUs 160-a, DUs 165-a, RUs 170-a, Non-RT RICs 175-a, Near-RT RICs 175-b, SMOs 180-a, Open Clouds (O-Clouds) 205, Open eNBs (O-eNBs) 210) may include one or moreinterfaces or may be coupled with one or more interfaces configured to receive or transmit signals (e.g., data, information) via a wired or wireless transmission medium. Each network entity 105, or an associated processor (e.g., controller) providing instructions to an interface of the network entity 105, may be configured to communicate with one or more of the other network entities 105 via the transmission medium. For example, the network entities 105 may include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other network entities 105. Additionally, or alternatively, the network entities 105 may include a wireless interface, which may include a receiver, a transmitter, or transceiver (e.g., an RF transceiver) configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other network entities 105.
[0099] In some examples, a CU 160-a may host one or more higher layer control functions. Such control functions may include RRC, PDCP, SDAP, or the like. Each control function may be implemented with an interface configured to communicate signals with other control functions hosted by the CU 160-a. A CU 160-a may be configured to handle user plane functionality (e.g., CU-UP), control plane functionality (e.g., CU-CP), or a combination thereof. In some examples, a CU 160-a may be logically split into one or more CU-UP units and one or more CU-CP units. A CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface, such as an El interface when implemented in an O-RAN configuration. A CU 160-a may be implemented to communicate with a DU 165-a, as necessary, for network control and signaling.
[0100] A DU 165-a may correspond to a logical unit that includes one or more functions (e.g., base station functions, RAN functions) to control the operation of one or more RUs 170-a. In some examples, a DU 165-a may host, at least partially, one or more of an RLC layer, a MAC layer, and one or more aspects of a PHY layer (e.g., a high PHY layer, such as modules for FEC encoding and decoding, scrambling, modulation and demodulation, or the like) depending, at least in part, on a functional split, such as those defined by the 3rd Generation Partnership Project (3GPP). In some examples, a DU 1 5-a may further host one or more low PHY layers. Each layer may beimplemented with an interface configured to communicate signals with other layers hosted by the DU 165-a, or with control functions hosted by a CU 160-a.
[0101] In some examples, lower-layer functionality may be implemented by one or more RUs 170-a. For example, an RU 170-a, controlled by a DU 165-a, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (e.g., performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like), or both, based at least in part on the functional split, such as a lower-layer functional split. In such an architecture, an RU 170-a may be implemented to handle over the air (OTA) communication with one or more UEs 115-a. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s) 170-a may be controlled by the corresponding DU 165-a. In some examples, such a configuration may enable a DU 165-a and a CU 160-a to be implemented in a cloudbased RAN architecture, such as a vRAN architecture.
[0102] The SMO 180-a may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network entities 105. For non-virtualized network entities 105, the SMO 180-a may be configured to support the deployment of dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (e.g., an 01 interface). For virtualized network entities 105, the SMO 180-a may be configured to interact with a cloud computing platform (e.g., an O-Cloud 205) to perform network entity life cycle management (e.g., to instantiate virtualized network entities 105) via a cloud computing platform interface (e.g., an 02 interface). Such virtualized network entities 105 can include, but are not limited to, CUs 160-a, DUs 165-a, RUs 170-a, and Near-RT RICs 175-b. In some implementations, the SMO 180-a may communicate with components configured in accordance with a 4G RAN (e.g., via an 01 interface). Additionally, or alternatively, in some implementations, the SMO 180-a may communicate directly with one or more RUs 170-a via an 01 interface. The SMO 180-a also may include a Non- RT RIC 175-a configured to support functionality of the SMO 180-a.
[0103] The Non-RT RIC 175-a may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence (Al) or Machine Learning (ML) workflows including modeltraining and updates, or policy-based guidance of applications / features in the Near-RT RIC 175-b. The Non-RT RIC 175-a may be coupled to or communicate with (e.g., via an Al interface) the Near-RT RIC 175-b. The Near-RT RIC 175-b may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (e.g., via an E2 interface) connecting one or more CUs 160-a, one or more DUs 165-a, or both, as well as an O-eNB 210, with the Near-RT RIC 175-b.
[0104] In some examples, to generate AI / ML models to be deployed in the Near-RT RIC 175-b, the Non-RT RIC 175-a may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 175-b and may be received at the SMO 180-a or the Non-RT RIC 175-a from nonnetwork data sources or from network functions. In some examples, the Non-RT RIC 175-a or the Near-RT RIC 175-b may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 175-a may monitor long-term trends and patterns for performance and employ Al or ML models to perform corrective actions through the SMO 180-a (e.g., reconfiguration via 01) or via generation of RAN management policies (e.g., Al policies).
[0105] The network architecture 200 may also support dynamic voltage swing control at one or more devices to mitigate interference during full duplex communications. For example, a network entity 105 (e.g., CUs 160-a, DUs 165-a, RUs 170-a, Non-RT RICs 175-a, Near-RT RICs 175-b, SMOs 180-a, Open Clouds (O- Clouds) 205, Open eNBs (O-eNBs) 210) may output a measurement configuration to a wireless communication device, such as a UE 115 or other network entity 105 for measuring signal power based on a capability report transmitted by the device. The device may measure an IPH among other values using the parameters of the measurement configuration, and may transmit an IPH report to the network entity 105. The network entity 105 may use the IPH report to signal recommended adjustments to voltage swing or to adjust a schedule for one or more communications for one or more devices for increased power savings and improved quality in communications.
[0106] FIG. 3 shows an example of a signaling diagram 300 that supports voltage swing control for robustness in wireless communications in accordance with one or more aspects of the present disclosure. The signaling diagram 300 may implement or beimplemented to realize aspects of the wireless communications system 100 or the network architecture 200. For example, the signaling diagram 300 may illustrate a network 305 including a network entity 105-a, which may be a network entity 105 as described with respect to FIGs. 1 and 2. The network entity 105-a may use one or more beams 310 to exchange signals 317 with one or more devices 315, including a device 315-a and a device 315-b, where each device 315 may be an example of a wireless communication device such as a UE 115 or a network entity 105 (e.g., CUs 160-a, DUs 165-a, RUs 170-a, base stations, among other network nodes). In some examples, the signaling diagram 300 may support dynamic voltage swing control, among other techniques, at one or more devices to mitigate interference during full duplex communications.
[0107] For example, the devices 315 may be configured for transmission in uplink to the network entity 105-a, reception in downlink, or to exchange one or more sidelink communications. Each device 315 may include respective transmitters, receivers, or transceivers. For example, the device 315-a may include a receiver 320 that may receive a signal 317-a via a beam 310-a (e.g., a receive beam) from the network entity 105-a or device associated with the network entity 105-a. In some cases, the network entity 105-a may output the signal 317-a via a beam 310-b (e.g., a transmit beam). The receiver 320 may include AFE circuitry 322, an ADC 324, processing circuitry 326, and automatic gain control (AGC) circuitry 328. The signal 317-a may be first received via the AFE circuitry 322, which may be an example of an antenna and additional supporting circuitry for amplification and other operations. After amplifying the signal, the AFE circuitry 322 may output the signal 317-a to the ADC 324 which may perform a digital conversion and output the resulting signal to the processing circuitry 326 for additional post-processing or other procedures before output to one or more components of the device 315-a. In some examples, the AGC circuitry 328 may exchange signaling with the processing circuitry 326 and the AFE circuitry 322 to perform AGC for received signals.
[0108] In some cases, the network entity 105-a may support full duplex communications. Full duplex communications may refer to simultaneous transmission and reception of signaling at one or more devices. For example, at the same time that the network entity 105-a transmits the signal 317-a to the device 315-a in downlink, thenetwork entity 105-a may receive a signal 317-b in uplink via a beam 310-c, which may be transmitted by the device 315-b via a beam 310-d. Each of the devices 315-a may in some examples support full duplex communications as well. Full duplex communications may reduce uplink and downlink contention in the network 305, thereby reducing latency for communication links (e.g., asymmetric links) of the network. Routing latency may also be reduced using full duplex communication. For example, one or more devices 315 may be lABs or repeaters, where route selection algorithms may activate adjacent hops simultaneously while an intermediate node operates in both downlink and uplink directions, reducing routing delay.
[0109] Full duplex communications may also increase throughput with a relatively lower SNR compared to non-full duplex communications, which may enable efficient transmission if SNR of the network 305 may be limited. For example, in FR2 and other frequency bands, SNR may be limited to ~30 decibels (dB) due to non-thermal impairments including phase noise, power amplifier non-linearity, full duplex residual side band (FDSB) communications, among other factors. In some cases, FR2 throughput may depend on SNR » 10 dB, with SNRmto increase throughput by a factor m. However, due to the ability to transmit and receive at the same time, throughput may increase in a full duplex system, and thus may utilize a lower SNR value. A system may also achieve reduction in latency and increased SNR by employing dynamic TDD (D-TDD). For example, in D-TDD, the network 305 may allocate transmission directions (e.g., to or from devices 315) dynamically for traffic adaptation in each cell of the network 305. Similar to FDD, D-TDD systems may also reduce latency and increase spectrum utilization via flexible and dynamic duplex operation.
[0110] In some examples, full duplex or D-TDD communications may increase interference in the network 305. One example of interference may be Direct Self Interference (DSI), in which a transmission device may generate interference to its own receiver directly. For example, a transmitter of the network entity 105-a transmitting signaling 317 may result in DSI at a receiver of the network entity 105-a. The network entity 105-a or the devices 315 may also experience Indirect Self Interference (IDSI) in which a transmitter of a device may generate interference to its own receiver via a reflector of the device, surrounding area, or network 305. FD systems may also include Cross-link interference (CLI) in which an adjacent aggressor device (such as anotherUE 115) in uplink may cause interference at a victim device 315. For example, the device 315-a may experience interference from the uplink signal 317-b of the device 315-b during reception if the signals 317-a and 317-b share overlapping time slots and other resources (e g., frequency resources). D-TDD may in some cases experience unpredictable CLI due to use of different transmission directions between adjacent cells. loin] Due to CLI, sharing resources between the two signals 317 may result in the signal 317-a received at the AFE circuitry 322 of the device 315-a including both a power of the originally transmitted signal 317-a in addition to a power contributed by the interference from the signal 317-b. Further, non-overlapping frequency resources for downlink and uplink transmissions may cause CLI if in close proximity in the frequency domain. For example, the signal 317-a received at the AFE circuitry 322 of the receiver 320 may include the originally transmitted signal 317-a in a first frequency range and the signal 317-b in a different non-overlapping frequency range. However, amplification at the AFE circuitry 322 may expand a width of each signal’s respective bandwidth in the frequency domain, which may cause the signal powers to overlap, similarly increasing an overall received signal power of the signal 317-a.
[0112] The total receive power of the signal 317-a may rise above an expected value due to interference, resulting in decreased signal quality. For example, increasing the total power of the received signal 317-a may increase a Vin of the signal seen at the input of the AFE circuitry 322, where the voltage of the amplified signal at the output of the AFE circuitry 322 may be represented by Vout. A total maximum Vout for the AFE circuitry 322 may be defined by a voltage swing 330-a, which may depend on an input power to the AFE circuitry 322. A level of the voltage swing 330-a may correspond to range of output voltage values over which an input signal is relatively linearly amplified. Increasing the level of the voltage swing 330-a may increase this range, whereas decreasing the level of the voltage swing 330-a may decrease this range.
[0113] For lower values of Vin, Vout may be amplified relatively linearly. However, this response may become non-linear as Vin increases. For example, Vout may increase less and less the more Vin increases. Further, in some cases, the signal may “clip” when output by the ADC 324 as the output signal for the ADC 324 may result in a quantized output at a threshold level, where the threshold level may in some cases be lower than the voltage swing 330-a. In some examples, the interference from the signal 317-b (e.g.,from shared or close proximity resources) may push the received power of the signal 317-a above a threshold 335-a at the end of a relative linear response region for a respective Vin and a given voltage swing 330. As the ratio of Vout to Vin decreases (and at sometimes results in clipping), an associated SNR may also decrease, resulting in a reduction in signal quality and a higher BER.
[0114] The processing circuitry 326 may in some examples perform post-processing to mitigate interference. For example, the processing circuitry 326 may include digital- front-end (DFE) circuitry and baseband processing circuitry, and may be operable to perform non-linear cancellation (NLIC), self-interference cancellation (SIC), digital post distortion (DPOD) correction, among other post processing techniques to improve a quality of a signal 317. However, post-processing techniques may be computationally expensive and inefficient, or may involve a relatively large dynamic range in the analog domain (for example, to reduce clipping at the AFE circuitry 322 and the ADC 324), which may increase power consumption at the device 315-a. Additionally, or alternatively, a robust front end (e.g., circuitry of AFE circuitry 322, DFE circuitry of the processing circuitry 326) may be included to achieve relatively high performance for relatively large quantities of devices 315 and network entities 105 (e.g., IABS, repeaters, UEs, gNBs), which may further increase power consumption and a respective area taken for circuitry.
[0115] In some cases (e.g., in an ideally static use case), the AGC circuitry 328 maybe able to converge on the summation of the interference and the main signal 317-a. For example, the AGC circuitry 328 may select a gain for the signal 317-a to maximize a related SNR, where related gain may increase with signal power (e.g., increase with receive signal strength indicator (RSSI) value). In an example, the AGC circuitry 328 may select a relatively low gain value initially for signals received at the device 315-a (e.g., for low expected interference, or in presence of blockers). The gain in such cases may be limited on a lower end by a thermal noise floor (kTBFG) of the AFE circuitry 322. Based on the increased power due to interference from the signal 317-b, the AGC circuitry 328 may converge on a difference between the originally transmitted signal 317-a and the interference, and may increase gain to a higher level to achieve a same SNR. However, doing so may increase an antenna input power (e.g., in dB milliwatts (dBm)) of the AFE circuitry' 322 while increasing noise in the network 305, which mayreduce a related link budget. Further, as interference may be dynamic, link performance may be further decreased due to AGC adjustment to maintain SNR values. Additionally, or alternatively, gain increase may be limited by a non-linearity of the AFE circuitry 322 and ADC 324, for example, where an upper limit may depend on a third order intermodulation distortion (IM3) of the AFE circuitry 322.
[0116] As described herein, interference may be mitigated by dynamically adjusting a voltage swing 330. Notably, as the voltage swing 330-a increases for the AFE circuitry 322, a corresponding dynamic range may increase for each of the components in the AFE circuitry 322, providing greater robustness in the presence of interference or blockers as well as avoiding decreased SNR by increasing a linear range of the Vout response. The voltage swing 330-a may also be directly dependent on a supplied voltage and may define power consumption at the AFE circuitry 322, and so increasing the voltage swing 330-a may result in greater power consumption. For example, increasing the voltage swing 330-a by a factor of 2 may result in an increase of ~6dB to the dynamic range, but may also consume ~4 times more power. However, by dynamically adjusting the voltage swing 330-a based on interference, such power costs may be significantly reduced.
[0117] For example, the network 305 may support additional signaling to enable dynamic voltage swing adjustment, among other techniques, to reduce a power cost of interference mitigation. For example, the network entity 105-a and the device 315-a may exchange signaling 340 indicating information related to interference mitigation, where the signaling 340 may include one or more uplink signals, downlink signals, the signal 317, among other signaling. In some examples, the network entity 105-a may signal an expected level of interference to the device 315-a via the signaling 340 or the signal 317-a, and the device 315-a may increase the voltage swing 330 or adjust a bandwidth accordingly to reduce interference. Additionally, or alternatively, the device 315-a may measure a receive power of signaling at the device (including interference) and periodically signal an IPH in an IPH report (e.g., IHR). In some cases, an IPH report for reception at the device 315-a may be similar to a power head room (PHR) report for transmissions from the device 315-a. The IPH may indicate how much the device 315-a may increase or decrease the voltage swing 330 while maintaining or to reach a target SNR value. Additionally, or alternatively, the network entity 105-a mayreschedule or adjust allocations of resources for communications across the network to increase performance or another key performance indicator (KPI), such as power savings. In some cases, such signaling may be described in further detail with respect to FIG. 4.
[0118] FIG. 4 shows an example of a signaling diagram 400 that supports voltage swing control for robustness in wireless communications in accordance with one or more aspects of the present disclosure. The signaling diagram 400 may implement or be implemented to realize aspects of the wireless communications system 100, the network architecture 200, or the signaling diagram 300. For example, the signaling diagram 400 may illustrate the signaling 340 between the network entity 105-a and the device 315-a of the network 305 to support dynamic voltage swing control, among other processes, to mitigate interference during full duplex communications (e.g., CLI from the device 315-b among other interference). The signaling diagram 400 may also illustrate signaling with another device 315-c, a scheduler 405, or may be implemented between any quantity of devices 315, network entities 105, or other components of the network 305.
[0119] In some examples, the device 315-a (e.g., a UE 115 or network entity 105 or any node in the network 305) may indicate to devices of the network 305 a capability to dynamically update a voltage swing 330. For example, the device 315-a may transmit (or otherwise output) a capability message 410-a to the network entity 105-a, where the capability message may indicate (e.g., via one or more fields or indicators) that the device 315-a is capable of dynamically updating the voltage swing 330 of the AFE circuitry 322 and ADC 324 of the device 315-a. The capability message 410-a may also indicate one or more other capabilities of the device 315 related to interference suppression. In some examples, the capability message may be transmitted in uplink control information (UCI) or within other control signaling. In some cases, the capability message 410-a may enable the network 305 to control a tradeoff between performance and power consumption for devices 315 and network entities 105.
[0120] In some examples, the network entity 105-a may obtain information related to interference or potential interference in the network 305. For example, the network entity 105-a may communicate with the scheduler 405-a, which may be part of the network entity 105-a or a separate node of the network entity 105-a, and may determinethat uplink communications from the device 315-b are scheduled to happen at a same time as downlink communications to the device 315-a or one or more other devices 315. In order to enable mitigation of this interference, the network entity 105-a may probe one or more devices 315 to determine how much IPH each device has based on a strength of signals received at each device. For example, in response to the capability message 410-a, the network entity 105-a may output (e.g., output wirelessly or through a physical or other medium, transmit) a measurement configuration message 415-a to the device 315-a regarding conditions under which the device 315-a may measure IPH for later application regarding voltage swing, or other parameters. In some cases, a measurement configuration message 415 may be output via different downlink message formats (MAC control element (MAC-CE), downlink control information (DCI), RRC, etc.).
[0121] In some examples, the measurement configuration message 415-a may indicate one or more parameters defining one or more conditions for measuring signal power at the device 315-a, or may request a device to perform measurements using parameters and to report a result in an IPH report. For example, the measurement configuration message 415-a may include one or more beam indexes corresponding to one or more receive beams at the device 315-a for which to measure a received signal power, or corresponding to one or more transmit beams for transmitting one or more signals for measurement using the one or more receive beams, or both. The measurement configuration message 410 may also indicate a time window (e.g., a time slot index A to a time slot index B) for performing measurements.
[0122] The measurement configuration message 415-a may also indicate to widen or narrow a reception bandwidth at the device 315-a. For example, the device 315-a may include one or more bandgap filters or bandpass filters to filter out signaling outside a target frequency bandwidth (e.g., frequency range) or set of bandwidths for reception. The message may indicate to “open” or narrow such filters (e g., widen range of a bandpass filter, narrow range of a band-gap filter) when measuring a received signal power to determine whether the device 315-a may experience more or less interference with a larger or narrower bandwidth range. That is, a total bandwidth sum of open frequency ranges for reception may be related to a headroom at the device 315-a.
[0123] The measurement configuration message 415-a may also indicate one or more general parameters related to measurement configurations or measurement types. For example, the measurement configuration message 415-a may indicate whether an IPH report is to be differential (e.g., compared to a previous IPH report) or absolute (e.g., relative to existing measurement). For example, an absolute report may indicate an absolute power value of received signals (e.g., reference signal receive power (RSRP), receive signal strength indicator (RS SI)), or a difference between a maximum power level and a current power level of reception to indicate how much more interference the device 315-a may receive in addition to current interference, or how far above a threshold (e.g., the threshold 335-a) the device already is. Parameters may also include whether to measure one or more maximum values over a time window, one or more average values over a time window, one or more means, or one or more other metrics.
[0124] The device 315-a may perform the one or more measurements in accordance with the one or more parameters of the measurement configuration message 415-a and transmit a corresponding IPH report 420-a. For example, after receiving the measurement configuration message 415-a, the device 315-a may monitor for and receive one or more reference signals transmitted by the network entity 105-a or another device (or other messages) during an indicated time window, via indicated receive beams, etc. and may make the indicated measurements. In some cases, the device 315-a may measure a signal power level of the one or more signals, such as a reference signal receive power (RSRP) or receive signal strength indicator (RS SI) in accordance with the one or more parameters for measurement.
[0125] In some cases, based on the measurements, the device 315-a may report an IPH in terms of measured power (e.g., relative power, absolute power) in decibels (dB). For example, a positive value (e.g., +dB) in the report may indicate available IPH, and may represent how far below a threshold (e.g., the threshold 335-a) a total receive power (e.g., average, instantaneous) for a signal is. That is, a positive value may indicate how much more power the device 315-a may receive in terms of signal or added from interference before crossing into a non-linear response region and having a reduction in SNR. A negative value (e.g., -dB) may thus indicate how far past a threshold limit (e.g., a threshold 335 related to linear region) a receive power is, or how much dB of power may be removed from a signal so the signal may enter back into alinear region and maximize SNR. IPH reports 420 may be transmitted according to one or more formats, which may also be indicated in the measurement configuration messages 415 (e.g., via MAC control element (MAC-CE), UCI, etc.). The report for the IPH may also indicate one or more transmission beam indexes, one or more receive beam indexes, a time window, an observed bandwidth (e.g., how open or narrow), used by the device 315-ato determine the IPH.
[0126] In some examples, the network entity 105-a may adjust a scheduling of one or more transmissions based on IPH reports 420. For example, the network entity 105-a may receive one or more additional IPH reports 420 from other devices 315 for which measurements were also requested. For example, the network entity 105-a may receive a capability message 410-b from, output a measurement configuration message 415-b to, and obtain an IPH report 420-b from the device 315-c. Based on the received IPH reports 420, the network entity 105-a (via the scheduler 405-a, which may be part of or in communication with the network entity 105-a), may identify one or more devices 315 with available IPH and may adjust a scheduling of communications to reduce interference at devices 315 experiencing a greater level of interference. For example, the IPH report 420-a may indicate that the device 315-a has a negative IPH (e g., -2dB), or that current receive power of a measured signal is 2 dB above the threshold 335-a, which may indicate too much interference at the device 315-a. The network entity 105-a may also receive an IPH report from the device 315-c that indicates a positive IPH value (e.g., +2 dB), or that a receive power is 2dB below the threshold 335-a. In other terms, the device 315-c may be able to “absorb” 2dB of additional signal power (e.g., due to interference) without a change in SNR.
[0127] The network entity 105-a may adjust the scheduling subject to the IPH reports 420. For example, via the scheduler 405, the network entity 105-a may adjust a spacing between frequencies or time slots of transmissions so that interference at the device 315-a is reduced. In some examples, the network entity 105-a may be able to adjust such frequencies due to the IPH available at the device 315-c by adjusting the resources of the device 315-c to increase interference received at the device 315-c without surpassing the threshold 335-a. In some cases, reallocating resources may be related to adjustments in bandwidth based on IPH reports. For example, a previous filter window of the device 315-c may filter out interference from the device 315-b (e.g., in aneighboring spectrum) resulting in a 2dB headroom. The measurement configuration message 415-b may indicate to widen a bandpass filter during measurements, where a receive power even with the added interference may still be below the threshold 335-a. The IPH reports 420 may in some cases indicate the one or more respective parameters of the measurement configuration messages 415 with which measurements were made. In some examples, the network entity 105 -a may indicate an updated schedule by outputting control messages 430, such as one or more control messages 430-a, which may schedule reception of messages 435, such as one or more messages 435-a based, on the updated scheduling.
[0128] By way of another example, the network 305 may mitigate interference by signaling to one or more target receive nodes (e.g., devices 315) regarding how much to increase or decrease a voltage swing 330 and associated dynamic range. For example, the network entity 105 -a may output update messages 425, including an update message 425-a and an update message 425-b. The update message 425-a may indicate to update the voltage swing 330-a at the device 315-a to adjust for interference. For example, based on the reported IPH of -2dB, the update message 425-a may indicate to adjust the voltage swing 330-a of the device 315-a (e.g., to a new voltage swing) during a specified time period to mitigate such interference. Similarly, the update message 425-b may indicate that the device 315-c may reduce a voltage swing to save power based on available headroom. Additionally, or alternatively, the device 315-a or 315-b may determine whether to adjust a respective voltage swing 330 based on a recommendation received in the update messages 425.
[0129] In some cases, the update messages 425 may include additional parameters. For example, an update message 425 may indicate a relevant time period for applying a new voltage swing 330. A time period may be based on scheduling and may be associated with time slots in which interference is expected or predicted, such as until an end of a transmission of the device 315-b. Additionally, or alternatively, an update message 425 may indicate a set of bandwidths and related voltage swings or dynamic ranges, such as a table of bandwidths and associated voltage swings or dynamic ranges. An update message 425 may also indicate one or more related beams and beam indexes (e.g., receive beams), or any quantity of time periods or voltage swings for a set of one or more beams.
[0130] Based on an update message 425 and related IPH report 420, a device 315 may update a voltage swing. For example, the device 315-a may update the voltage swing 330-a to a second, higher, voltage swing value with a greater dynamic range during an indicated time period to mitigate interference from the device 315-b, and may monitor for and receive the one or more messages 435-a during the time period in accordance with the higher voltage swing value. Following the end of the time period, the device 315-a may return to monitoring for and receiving messages such as the messages 435 using a previous voltage swing value once transmissions from the device 315-b are complete. By way of another example, the update message 425-b may indicate to the device 315-b to decrease a voltage swing 330 to save power based on available IPH. A device 315 may also adjust an operating bandwidth, or one or more additional parameters based on indications in an update message 425. For example, the update message 425-b may indicate to the device 315-c to widen a frequency range of allowed frequencies of a filter. In some cases, the device 315-a may treat the indications in the update messages 425 as commands, or as recommendations, and may determine whether to use a recommendation based on one or more parameters at the device 315-a (e.g., power, application or message priority, cost and benefit analysis).
[0131] In some examples, a device 315 may signal a connection between performance and an updated voltage swing by indicating one or more estimated parameters in an IPH report 420. For example, the device 315-a may determine an IPH of -2 dB based on performing measurements using the measurement configuration message 415-a, and may estimate a second voltage swing 330 to reduce interference so that IPH = 0 dB as well as an estimated higher SNR value for the second voltage swing. The device 315-a may include the measured IPH, estimated IPH, current SNR, estimated SNR, current voltage swing 330-a, and second voltage swing 330 in the IPH report 420-a, among other performance values, mutual information, and other estimated values. Additionally, or alternatively, the device 315-a or another device may determine an estimated degradation in performance using a new voltage swing value or allowed bandwidth. For example, the device 315-b may determine that a voltage swing, scheduling adjustment, or widening of bandwidth may result in a decrease in 2dB for IPH, but may result in a zero change in SNR due to a current IPH of +2dB. The device 315-b may also indicate another voltage swing, scheduling adjustment, or widening ofbandwidth that may result in a decrease in more than 4dB, as well as an estimated reduction in SNR in dB as a result. The devices 315 may also indicate estimated changes in link performance (e.g., power savings or power consumption increase). In some cases, the recommended or indicated voltage swing or other parameters in the update messages 425 may be based on incorporating these estimated results into one or more decisions. Indicating estimated changes related to such adjustments may allow the network entity 105-a to adjust scheduling or make recommendations in update messages 425 based on additional parameters and context (e.g., may prioritize power savings for lower power mode devices, or signal power for devices with available power or poor reception). In some cases, the network entity 105-a may send a control message to the device 315-a indicating permission for the device 315-a to autonomously adjust (e.g., reduce) a voltage swing level, even if such adjustment may impact performance.
[0132] Additionally, or alternatively, the network entity 105-a may signal predicted interference intervals to devices 315. For example, the update message 425-a may indicate potential interference during a time period when both the device 315-a and the device 315-b are communicating with the network entity 105-a. Indicated potential interference may allow the devices 315 to determine whether or not to adjust parameters (e.g., voltage swing, dynamic range, allowed bandwidth) based on cost or benefit and other factors without adjusted scheduling or update messages 425 from the network entity 105-a. Other messaging may also be output to devices 315 to signal predicted interference levels and time periods to allow the devices 315 to make decisions to increase power savings and maximize SNR.

[0138] In some examples, the IPH report indicates one or more measured values including the signal power level. The IPH report may also indicate one or moreestimated values corresponding to a set of one or more voltage swing levels (e.g., a second set) including at least a third voltage swing level. In some cases, each of the one or more estimated values may be associated with a respective change in link performance at the device 315-d as a result of applying a respective voltage swing level of the second set of one or more voltage swing levels. For example, the one or more estimated values may indicate a performance value, mutual information, one or more SNRs, or any combination thereof, associated with the respective voltage swing levels. Additionally, or alternatively, the third voltage swing level may be different from the current voltage swing level and a second voltage swing level, where the second voltage swing level may be associated with the amount of IPH.

The update message may also indicate a time duration for applying the second voltage swing level. In some examples, the update message may indicate a set of one or more voltage swing levels (e.g., a first level) including the second voltage swing level, one or more bandwidths associated with the first set of one or more voltage swing levels, one or more beams, or any combination thereof. For example, the update message may indicate a table of voltage swing levels and associated beams, bandwidths (e.g., for a dynamic range, or for a bandpass or bandgap filter).

Additionally, or alternatively, outputting the one or more control messages may be based on a set of multiple IPH reports associated with a set of multiple wireless communications devices including the device 315-d.
[0141] At 530, the device 315-d, the network entity 105-b, or both, may optionally communicate (e.g., obtain, output, receive, transmit, or otherwise communicate) the one or more messages in accordance with the set of resources. For example, the networkentity 105-b may optionally output, and the device 315-d may optionally obtain (e.g., receive via the circuitry of the device 315-d), one or more messages in accordance with the second voltage swing level based on updating, by the device 315-d, the current voltage swing level to the second voltage swing level. The device 315-d may also transmit one or more messages to the network entity 105-b, and the device 315-d and the network entity 105-b may communicate the one or more messages with one or more other devices 315 or network entities 105 using the resources indicated by the one or more control messages.

A non-transitory storage medium may be any available medium that may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc. Disks may reproduce data magnetically, and discs may reproduce data optically using lasers. Combinations of the above are also included within the scope of computer-readable media. Any functions or operations described herein as being capable of being performed by a memory may be performed by multiple memories that, individually or collectively, are capable of performing the described functions or operations.
[0284] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of’ or “one or more of’) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the presentdisclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on.”
[0285] As used herein, including in the claims, the article “a” before anoun is open- ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a,” “at least one,” “one or more,” “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components,” and referring to “the component” subsequently in the claims maybe understood to be equivalent to referring to “at least one of the one or more components.” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components.”
[0286] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database or another data structure), ascertaining and the like. Also, “determining” can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory) and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
[0287] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same firstreference label irrespective of the second reference label, or other subsequent reference label.
[0288] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” used herein means “serving as an example, instance, or illustration,” and not “preferred” or “advantageous over other examples.” The detailed description includes specific details for the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
[0289] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
