Technical Field
[0003] The following relates to wireless communications, including power configuration for self-interference measurements. Background Art
[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing 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, advanced LTE (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 various technologies, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices, which may be further referred to as user equipment (UE).
[0005] A UE may transmit signals to one or more other wireless devices, such as a base station. In some cases, the UE may experience self-interference (SI), where the signal transmitted by the UE interferes with the UE's reception of other signals. For example, the transmitted signal may be reflected back to the UE by an object, which may be an example of a clutter echo. In other cases, the transmitted signal may leak from the UE's transmit antenna to the UE's receive antenna, which may be an example of near-field SI.

[0057] Detailed description
[0058] A user equipment (UE) can communicate with one or more other wireless communication devices in a wireless communication system. The UE can transmit signals to and receive signals from the other devices. In some cases, the UE can operate in full-duplex mode, where the UE can transmit and receive signals during the same set of resources (such as at the same time or on the same frequency, or both).
[0059] The UE may experience self-interference (SI). SI may occur when a signal transmitted by the UE interferes with the reception of other signals by the UE. In some cases, the UE may experience a spurious echo, a type of SI in which a signal transmitted by the UE is reflected back to the UE, and the reflected signal may interfere with the UE's reception of other signals. The reflected signal may interfere with the UE's receive antenna or port. The signal may be reflected back to the UE by a physical object, which in some cases may be another wireless device. The SI may also be an example of a far-field reflection. The transmitted signal may be partially or completely reflected. In other cases, the transmitted signal may leak from the UE's transmit antenna or port to the UE's receive antenna or port, and may thereby cause SI. The signal leakage may be an example of near-field SI or near-field leakage.
[0060] The UE may perform SI measurement (SIM) to measure and mitigate the causes of SI. To perform SIM, the UE may transmit a signal and measure the SI caused by the signal. The transmitted signal may be a signal dedicated to SIM purposes, or may be another type of signal, such as a control or data signal. The UE may determine the transmit power used to transmit the SIM signal. Low power may be sufficient for the UE to transmit the SIM signal for detecting near-field SI. Low-power transmission may cause a lower level of interference to other ongoing communications at the UE or other wireless devices in the system, and may also use less UE power. However, low-power transmission may not be able to reach distant objects and may therefore be less useful for detecting interference echoes. Thus, the UE may use higher power to transmit the SIM signal for detecting interference echoes. In addition, in some cases, the UE may transmit a SIM signal that may also be used by other wireless devices. In these cases, the UE may also use higher power to transmit the SIM signal.
[0061] The UE can therefore perform SIM for near-field SI at a lower power and SIM for clutter echo at a higher power. The UE can perform both SIMs using a mixed transmit power configuration. The transmit power configuration may include performing near-field SIM more frequently at a lower power and performing clutter echo SIM less frequently at a higher power.
[0062] In some cases, the UE may identify the two power levels and the repetition frequency of performing SIM. In other cases, the UE may receive an indication from another wireless device (such as a base station) that includes the configuration of the two power levels and the repetition frequency for each SIM. After performing one or both types of SIM, the UE may transmit a measurement report including these measurements. The UE may receive an indication of a new power level for performing the transmission so that the measured SI is reduced or mitigated to a threshold level.
[0063] In addition, the SIM configuration may include a common periodic SIM object. The common periodic SIM object may include specific configurations for the transmit power for each type of SI, the repetition frequency of the signal used to transmit each type of SI, and other parameters. There may be multiple different periodic SIM objects that the UE can use to perform SIM.
[0064] Aspects of the present disclosure are initially described in the context of wireless communication systems. Aspects of the present disclosure are subsequently described with reference to process flows. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to power configuration for self-interference measurements.
[0065] Figure 1 An example of a wireless communication system 100 supporting a power configuration for self-interference measurement according to aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.
[0066] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be different forms of devices or devices with different capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which UEs 115 and base stations 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support signal communication according to one or more radio access technologies.
[0067] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be different forms of devices or devices with different capabilities. Figure 1 1. The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relays, integrated access and backhaul (IAB) nodes, or other network equipment), such as Figure 1 As shown in .
[0068] Each base station 105 can communicate with the core network 130, or with each other, or both. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate with each other directly (e.g., directly between the base stations 105), indirectly (e.g., via the core network 130), or both directly and indirectly over the backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul links 120 can be or include one or more wireless links.
[0069] One or more of the base stations 105 described herein may include or may be referred to by one of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home Evolved Node B, or other suitable terminology.
[0070] UE 115 may include or 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 "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or 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, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects, such as appliances or vehicles, meters, etc.
[0071] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 As shown in .
[0072] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates 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 for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The 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 duplex (FDD) and time division duplex (TDD) component carriers.
[0073] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by a UE 115. A carrier may operate in a standalone mode in which initial acquisition and connection may be performed by a UE 115 via the carrier, or a carrier may operate in a non-standalone mode in which the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).
[0074] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).
[0075] A carrier may be associated with a particular bandwidth of radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) of a carrier of a particular radio access technology. Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.
[0076] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique 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 include one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of communications with UE 115.
[0077] One or more parameter sets for a carrier may be supported, where the parameter set may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter designs. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for the UE 115 may be limited to the one or more active BWPs.
[0078] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, which can be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the maximum supported subcarrier spacing, and N fThe maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources 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).
[0079] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time 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 number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of code element periods (e.g., depending on the length of the cyclic prefix added before each code element period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-time slots containing one or more code elements. Excluding the cyclic prefix, each code element period may contain one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the operating band.
[0080] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).
[0081] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for physical control channels may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more 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 the number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .
[0082] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with a base station 105 (e.g., on a carrier) and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish between adjacent cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which the logical communication entity operates. The scope of such a cell may range from a smaller area (e.g., a structure, a subset of structures) to a larger area depending on various factors (such as the capabilities of the base station 105). For example, a cell may be or include a building, a subset of buildings, or an external space between or overlapping geographic coverage areas 110, among other examples.
[0083] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have a service subscription with a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 (compared to a macro cell), and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 that have a service subscription with the network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells and may also support communications over one or more cells using one or more component carriers.
[0084] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.
[0085] In some examples, base stations 105 can be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.
[0086] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and transmissions from different base stations 105 may not be aligned in time in some examples. The techniques described herein may be used for either synchronous or asynchronous operation.
[0087] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that incorporate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents it to a person interacting with the application. Some UEs 115 may be designed to collect information or implement 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, wilderness survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.
[0088] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating over a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.
[0089] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. The UE 115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication and can be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably herein.
[0090] In some examples, UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base station 105.
[0091] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, the vehicles in the V2X system can use vehicle-to-network (V2N) communication to communicate with roadside infrastructure (such as roadside units), with the network, or with both, via one or more network nodes (e.g., base station 105).
[0092] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and the EPC or 5GC may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnects to external networks. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0093] Some network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., base station 105).
[0094] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or the decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter long. UHF waves can be blocked or redirected by buildings and environmental features, but these waves can penetrate various structures sufficiently for macrocells to provide service to UEs 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) compared to transmissions using the lower frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.
[0095] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as a centimeter band) or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be smaller and more closely spaced than the UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.
[0096] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band, such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) may employ carrier sensing for conflict detection and avoidance. In some examples, operations in the unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in the licensed band. Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.
[0097] The base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can 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, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having several rows and columns of antenna ports that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.
[0098] The base station 105 or the UE 115 can use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, a receiving device may receive multiple signals via different antennas or different antenna combinations. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits 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 for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.
[0099] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., base station 105, 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 can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with that device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).
[0100] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. The transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or a receiving device (such as the UE 115)) to identify a beam direction for later transmission or reception by the base station 105.
[0101] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a recipient device, such as UE 115. In some examples, a beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.
[0102] In some examples, transmission by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may transmit reference signals that may be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). 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 by base station 105 in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).
[0103] A receiving device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may attempt multiple receive directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array (e.g., different directional listening weight sets), or 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 "listening according to different receive configurations" or "listening according to receive directions." In some examples, the receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving data signals). The single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).
[0104] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate on the logical channel. The media access control (MAC) layer can perform priority handling and multiplex the logical channel into the transport channel. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission of the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer that supports user plane data between the UE 115 and the base station 105 or the core network 130. In the physical layer, the transport channel can be mapped to the physical channel.
[0105] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid Automatic Repeat Request (HARQ) feedback is a technique for increasing the likelihood that data is correctly received on communication link 125. 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 MAC layer throughput in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a particular time slot for data received in a previous symbol in that time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or based on some other time interval.
[0106] UE 115 may experience various types of SI, perform interference measurement procedures, and identify interference mitigation procedures. For example, UE 115 may experience clutter echo, which is caused by a signal transmitted by UE 115 reflecting off an object back to UE 115 and causing interference at UE 115's receive antenna. UE 115 may also experience interference caused by the transmitted signal leaking into UE 115's receive port or antenna, which may cause near-field SI. UE 115 may identify a configuration for performing SI, where the configuration indicates a first transmit power associated with a first transmission and a second transmit power associated with a second transmission. In some examples, the second transmit power is higher than the first transmit power. UE 115 may transmit multiple signals, each signal identifying a different type of SI. For example, UE 115 may transmit a first transmission at a first transmit power and a second transmission at a second transmit power, where the first transmission is associated with a first repetition frequency and the second transmission is associated with a second repetition frequency. UE 115 may measure SI based on transmitting the first transmission and the second transmission.
[0107] Figure 2 An example of a wireless communication system 200 that supports power configurations for self-interference measurements in accordance with aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. Figure 2 Including UE115-a, which can be as shown in FIG. Figure 1 An example of a UE 115 is described. Figure 2 Also included is a base station 105-a, which may be as described with reference to Figure 1 An example of a base station 105 is depicted. Base station 105-a may serve one or more UEs 115 located within coverage area 110-a. UE 115-a may be an example of an integrated access and backhaul (IAB) node, such as a mobile terminal (MT), a distributed unit (DU), or another child node. Base station 105-a may be an example of a network node, including an IAB node, such as a DU or a central unit (CU), or another parent node.
[0108] UE 115-a may include an antenna array 230. Antenna array 230 may include a transmit antenna 235, which may include a transmit beam. Antenna array 230 may also include a receive antenna 240, which may include a receive beam. UE 115-a may receive a downlink transmission from base station 105-a on channel 205. UE 115-a may receive the downlink transmission using receive antenna 240 (e.g., the beam of receive antenna 240). UE 115-a may transmit an uplink transmission to base station 105-a. UE 115-a may transmit the uplink transmission using transmit antenna 235 (e.g., the beam of transmit antenna 235). In some cases, the uplink transmission may be reflected back to receive antenna 240 of UE 115-a. The reflected signal may interfere with the reception of other signals (e.g., the downlink signal from base station 105-a) and may therefore cause SI.
[0109] UE 115-a may experience clutter echoes and near-field SI. Clutter echoes may include SI caused by reflections of signals from objects. For example, UE 115-a may transmit a signal that may be reflected from an object (such as object 225) back to receive antenna 240. Near-field SI may include signal leakage of a signal transmitted by transmit antenna 235, where the transmitted signal may be detected by receive antenna 240.
[0110] To mitigate SI, UE 115-a may perform SIM. UE 115-a may perform SIM with multiple power settings. UE 115-a may use a high-power signal to measure clutter echo SI because high power may be more likely to reach potential clutter echo-causing objects, such as object 225. UE 115-a may use a lower-power signal to measure near-field interference because low power may be sufficient to detect near-field interference while also avoiding interfering with other ongoing transmissions. Thus, UE 115-a may transmit two different signals for SIM, one for SIM of clutter echoes and one for measurement of near-field SI. In some cases, these signals may be transmitted specifically for the purpose of SIM, while in other cases, these signals may be transmitted for other primary purposes (e.g., other scheduled control or data signals), and these signals may also be used by UE 115-a for SIM.
[0111] UE 115-a may transmit a first transmission 215 for near-field SI measurement. UE 115-a may transmit the first transmission 215 at low power and according to a first repetition frequency. The first repetition frequency may be a periodic or aperiodic schedule according to which UE 115-a may repeatedly transmit the first transmission 215 for near-field SI measurement. After transmitting the first transmission 215 using transmit antenna 235 (e.g., as shown within antenna array 230), UE 115-a may receive the leakage signal using receive antenna 240. UE 115-a may measure the SIM of the first transmission 215.
[0112] UE 115-a may transmit a second transmission 220-a for measuring a spurious echo (e.g., caused by object 225) with a higher power so that the second transmission 220-a is more likely to reach the object and be reflected by the object. UE 115-a may transmit the second transmission 220-a according to a second repetition frequency. In some cases, the first repetition frequency may be higher than the second repetition frequency. In this way, UE 115-a may transmit the first transmission 215 more frequently than the second transmission 220-a. When transmitting the second transmission 220-a, in the event that the second transmission 220-a is reflected by an object (such as object 225), UE 115-a may receive the reflected second transmission 220-b. UE 115-a may measure the SIM of the second transmission 220-a.
[0113] In some cases, UE 115-a may independently determine the power level and repetition frequency of transmissions 215 and 220-a. In other cases, base station 105-a may transmit SIM configuration 210, which may include an indication of the power level, repetition frequency, and other parameters for performing SIM. UE 115-a may receive SIM configuration 210 and may transmit first transmission 215 and second transmission 220-a using the indicated parameters.
[0114] Based on measuring the near-field SI with the first transmission 215 and measuring the interference echo with the second transmission 220-a, the UE 115-a can transmit a report of the detected interference to the base station 105-a. Based on the report, the base station 105-a can identify the transmit power for future transmissions of the UE 115-a so that the future transmissions can have a low probability of causing either type of SIM. The future transmissions can also include subsequent signals transmitted for the purpose of SIM, or can be other control and data signals. In other cases, the UE 115-a can determine (e.g., in the absence of configuration information received from the base station 105-a) the transmit power for future transmissions of the UE 115-a based on the identified interference echo or near-field SI, or both.
[0115] In some cases, UE 115-a may identify a common periodic SIM object. The common periodic SIM object may include multiple transmit power configurations (e.g., transmit powers for a first transmission 215 and a second transmission 220-a). The common periodic SIM object may indicate different transmit power configurations that may be applied to transmit different repetitions of the first transmission 215 and the second transmission 220-a. For example, the common periodic SIM object may indicate a first power level for a first transmission repetition of the first transmission 215, a different power level for a second transmission repetition of the first transmission 215, and then return to the first power level for a third transmission repetition of the first transmission 215. The same or a different common periodic SIM object may be applied to the second transmission 220-a. UE 115-a may follow the common periodic SIM object for the second transmission 220-a, but there may be more time between repetitions of the second transmission 220-a than for the first transmission 215.
[0116] A common periodic SIM object may vary in power for each repetition, but the transmission resources, measurement procedures, transmit and receive beam configurations, and SIM reference signal configurations may remain the same for each different repetition. The intra-object association of different transmit power settings with SIM repetitions may be indicated via a bitmap, an offset, a periodicity, or a combination thereof. A common periodic SIM object may also be associated with multiple reporting objects, where each reporting object may be associated with one or more instances of a SIM repetition (each instance having a different transmit power setting). In some cases, UE 115-a may receive the common periodic SIM object from base station 105-b in SIM configuration 210. In other cases, UE 115-a may determine the common periodic SIM object based on configuration (e.g., pre-configuration) or other signaling.
[0117] In other cases, UE 115-a may use different periodic SIM objects that differ in repetition frequency, power settings, and other parameters (e.g., transmit and receive beams, measurement configuration, and other parameters). These other periodic SIM objects may also be indicated in SIM configuration 210, or may be identified at UE 115-a through other signaling, or based on configuration at UE 115-a (e.g., pre-configuration).
[0118] In some cases, UE 115-a may transmit an indication of the SIM configuration used by UE 115-a to other network nodes. The SIM configuration may include respective transmit power levels for first transmission 215 and second transmission 220-a. The SIM configuration may be the same as SIM configuration 210 received from base station 105-a, or may be a SIM configuration determined at UE 115-a. The network node that receives the indication of the SIM configuration from UE 115-a may use the SIM configuration to receive first transmission 215 and second transmission 220-a and may use these transmissions to perform other measurements and communications.
[0119] For example, UE 115-a may be a UE or an IAB MT and may transmit an indication of the SIM configuration to a network node, which may be a base station 105-a, another UE 115, an IAB MT, a serving node, or a parent node. In another example, UE 115-a may be a base station, an IAB DU, or a serving node and may transmit an indication of the SIM configuration to a network node, which may be a UE 115, a child IAB node, a parent IAB node, or another DU.
[0120] In another scenario, a network node may receive the SIM configuration from UE 115-a and may use the information to configure the SIM or other operations at other wireless devices. In these scenarios, the network node may be a control node, such as base station 105, a central unit, or a parent node; UE 115-a may be UE 115, an IAB MT, an IAB DU; and the other wireless devices may be UE 115, an IAB MT, a base station 105, or an IAB DU. These other wireless devices may measure signals transmitted by UE 115-a (e.g., based on receiving additional configuration information from the network node, which may be based on a report of the SIM configuration from UE 115-a). The other wireless devices may use these signals (e.g., first transmission 215, second transmission 220-a) to perform cross-link interference (CLI) measurements. The CLI may include interference from UE 115-a to other wireless devices.
[0121] Figure 3 An example of a process flow 300 for supporting power configuration for self-interference measurement in accordance with aspects of the present disclosure is illustrated. In some examples, the process flow 300 may implement aspects of the wireless communication system 100. The process flow 300 includes a UE 115-b, which may be a UE 115-b as described with reference to FIG. Figure 1 and 2 1. The UE 115-b may be an example of a UE 115, an IAB node (such as an MT, DU), or another sub-node, or a combination thereof. The process flow 300 also includes a base station 105-b, which may be as described with reference to FIG. Figure 1 and 2 Described as an example of a base station 105. Base station 105-b may be an example of a base station 105, a network node, an IAB node (such as a DU or CU), or another parent node, or a combination of these.
[0122] At 305 , the base station 105 - b may identify a configuration for performing SIM, wherein the configuration may indicate a first transmit power associated with the first transmission and a second transmit power associated with the second transmission, wherein the second transmit power is higher than the first transmit power.
[0123] In some cases, at 310, the base station 105-b may transmit an indication of the identified configuration for performing SI, where the configuration indicates a first repetition frequency associated with the first transmission and a second repetition frequency associated with the second transmission.
[0124] At 315 , UE 115 - b may identify a configuration for performing SIM, where the configuration may indicate a first transmit power associated with the first transmission and a second transmit power associated with the second transmission, where the second transmit power is higher than the first transmit power.
[0125] In some cases, UE 115-b may identify the configuration information based on receiving the configuration information including the indication of the first transmit power and the second transmit power at 310. In other cases, UE 115-b may determine at least the first transmit power or the second transmit power for performing configuration of the SIM. This determination may be based on pre-configuration or may be determined without signaling from another device (e.g., from base station 105-b). In these cases, UE 115-b may transmit an indication of the determined first transmit power or second transmit power.
[0126] In some cases, UE 115-b may identify a common SIM object for a set of SIM opportunities, wherein the common SIM object may define a common set of measurement parameters for the set of SIM opportunities. UE 115-b may apply the common set of measurement parameters and a first transmit power configuration corresponding to a first transmit power for a first subset of the set of SIM opportunities. UE 115-b may also apply the common set of measurement parameters and a second transmit power configuration corresponding to a second transmit power for a second subset of SIM opportunities. In some of these cases, UE 115-b may then identify an association between the first transmit power configuration and the first subset of the set of SIM opportunities, and an association between the second transmit power configuration and the second subset of the set of SIM opportunities, based on a bitmap. In some of these cases, UE 115-b may then identify an association between the first transmit power configuration and the first subset of the set of SIM opportunities, and an association between the second transmit power configuration and the second subset of the set of SIM opportunities, based on a periodicity associated with the first subset of the set of SIM opportunities and the second subset of the set of SIM opportunities, an offset between the first subset and the second subset, or a combination thereof.
[0127] At 320, UE 115-b may transmit a first transmission at a first transmit power; and at 325, UE 115-b may transmit a second transmission at a second transmit power. The first transmission may be associated with a first repetition frequency and the second transmission may be associated with a second repetition frequency. The first repetition frequency may be higher than the second repetition frequency. As such, UE 115-b may transmit the first transmission more frequently than the second transmission.
[0128] The first transmission may be used to measure a first type of SI and the second transmission may be used to measure a second type of interference. For example, the first type of SI may be associated with near-field SI and the second type of SI may be associated with reflections from an object (e.g., a nuisance echo).
[0129] At 330, UE 115-b may measure SI based on transmitting the first transmission and the second transmission. UE 115-b may detect a second type of SI (e.g., a clutter echo) using the second transmission transmitted at the second transmit power. UE 115-b may identify a third transmit power different from the second transmit power based on detecting the second type of interference. UE 115-b may transmit one or more third transmissions using the third transmit power in one or more subsequent SIM occasions. UE 115-b may also perform a measurement procedure or a mitigation procedure for the second type of SI based on transmitting the one or more third transmissions.
[0130] In some cases, UE 115-b may transmit a report including an indication of the second type of SI at 335. The report may be a measurement report. UE 115-b may subsequently receive configuration information for a third transmit power, wherein identifying the third transmit power is based on receiving the configuration information.
[0131] In these cases, UE 115-b may determine a third transmit power and may transmit an indication of the determined third transmit power. In some cases, UE 115-b may receive an indication of confirmation of the third transmit power, and UE 115-b may identify the third transmit power based on receiving the indication of confirmation of the third transmit power.
[0132] In a scenario where UE 115-b uses a common SIM object to perform SIM, UE 115-b may transmit a first report including first measurement results corresponding to a first subset of the SIM opportunity set, and UE 115-b may also transmit a second report including second measurement results corresponding to a second subset of the SIM opportunity set.
