Transmission power adjustment of synchronization signal block (SSB)

Abstract

The present disclosure provides systems, methods, and apparatuses for transmitting synchronization signal blocks (SSBs) using adjusted transmit power. In one aspect, a power offset can be configured for one or more SSB sets. The power offset can be configured to be applied to an SSB set based on a duplexing mode of one or more of a transmitter wireless node (transmitting the SSB) or a receiver wireless node (receiving the SSB). The duplexing mode can be based on whether the transmitter receiver node or the wireless receiver node is operating in a full duplex mode, or can be based on a resource configuration associated with resources used to transmit the SSB. Some techniques and apparatuses described herein also provide signaling to support transmission of SSBs using adjusted transmit power, as well as techniques for receiving and processing SSBs using adjusted transmit power.

[0002] This patent application claims priority to U.S. nonprovisional patent application No. 17 / 443,294, filed July 23, 2021, entitled “TRANSMIT POWER ADJUSTMENT FORSYNCHRONIZATION SIGNAL BLOCK (SSB)”, which is expressly incorporated herein by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communication and to techniques for adjusting the transmit power of a synchronization signal block (SSB). Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

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

[0006] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, or global level. New Radio (NR) (which may also be referred to as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and using CP-OFDM or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to better support mobile broadband internet access.

[0063] For the purpose of describing the innovative aspects of this disclosure, the following description is directed to certain embodiments. However, those skilled in the art will readily recognize that the teachings herein can be applied in a variety of different ways. Some examples in this disclosure are based on wireless and wired local area network (LAN) communications according to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless standard, the IEEE 802.3 Ethernet standard, and the IEEE 1901 power line communication (PLC) standard. However, the described embodiments can be implemented in any device, system, or network capable of transmitting and receiving radio frequency signals according to any of the wireless communication standards, including the IEEE 802.11 standard, etc. Standard, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Global System for Mobile Communications (GSM), GSM / General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunking Radio (TETRA), Wideband CDMA (W-CDMA), Evolved Data Optimized (EV-DO), 1xEV-DO, EV-DO Rev A, EV-DO Rev B, High-Speed ​​Packet Access (HSPA), High-Speed ​​Downlink Packet Access (HSDPA), High-Speed ​​Uplink Packet Access (HSUPA), Evolved High-Speed ​​Packet Access (HSPA+), LTE, AMPS, or other known signals used for communication within wireless, cellular, or Internet of Things (IoT) networks, such as systems utilizing 3G, 4G, 5G, or other implementations thereof.

[0064] Wireless networks can use full-duplex (FD) communication to increase throughput and improve the utilization of communication resources. FD communication involves using the same resources to perform two or more communications. FD communication contrasts with half-duplex (HD) communication, in which only one communication is performed on time and frequency resources. Examples of FD communication include transmitting and receiving on the same time and frequency resources, and transmitting two or more communications on the same time and frequency resources (sometimes referred to as spatial division multiplexing transmission (SDM-TX) or enhanced duplex). FD communication may present certain challenges, such as self-interference between transmission and concurrent reception, increased power usage that may violate the total transmit power limit of the wireless node, and increased signal-to-interference-plus-noise ratio (SINR) requirements at the FD receiver wireless node.

[0065] Synchronization signal blocks (SSBs) can be used to perform various tasks in wireless networks, such as synchronization, radio resource management (RRM), radio link control (RLC), beam management, etc. Typically, groups of SSBs (such as synchronization signal burst sets (SS burst sets) or sets of SSBs transmitted by a transmitter wireless node) can be transmitted with constant power relative to each other. However, in wireless networks utilizing FD communication, a uniform approach to SSB transmission power (where all SSBs are transmitted at the same power) can lead to suboptimal performance. As an example, a transmission power sufficient for reception at an FD-capable receiver wireless node may not be suitable for an FD-capable transmitter wireless node, as this power may cause significant self-interference at the FD-capable transmitter wireless node, or may exceed the total transmission power limit of the FD-capable transmitter wireless node.

[0066] Some of the techniques and apparatus described herein implement the transmission of SSBs using adjusted transmit power. For example, some of the techniques and apparatus described herein implement the application of power offset for one or more sets of SSBs. The power offset can be configured to apply a duplex mode to the set of SSBs based on one or more of the duplex modes of either the transmitter radio node (transmitting the SSB) or the receiver radio node (receiving the SSB). The duplex mode can be based on whether the transmitter receiver node or the receiver radio node is operating in FD mode, or it can be based on resource configuration associated with the resources used to transmit the SSBs. Some of the techniques and apparatus described herein also provide signaling for supporting the transmission of SSBs using adjusted transmit power, and techniques for receiving and processing SSBs using adjusted transmit power.

[0067] Specific embodiments of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. By transmitting SSBs at different transmit powers, self-interference at the transmitter wireless node can be reduced, and the total transmit power limit of the transmitter wireless node can be met more consistently, thereby increasing throughput and improving the utilization of wireless communication resources. Furthermore, acceptable SINR can be achieved at receiver wireless nodes with FD capability, thereby increasing throughput and reducing the occurrence of failed SSB reception. Additionally, interference at nodes other than the transmitter node can be reduced by adjusting the transmit power of the SSBs.

[0068] Figure 1This is a schematic diagram illustrating an example of a wireless network 100. Wireless network 100 may be or may include elements of a 5G (e.g., New Radio (NR)) network or a 4G (e.g., LTE) network, etc. Wireless network 100 may include one or more base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), or other network entities. Base station 110 is the entity that communicates with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, or a Transmit / Receive Point (TRP). Each base station 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of ​​base station 110 or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0069] Base station 110 can provide communication coverage for macro cells, pico cells, femtocells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Base station 110 for macro cells can be referred to as a macro base station. Base station 110 for pico cells can be referred to as a pico base station. Base station 110 for femtocells can be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS110a can be a macro base station for macro cell 102a, BS110b can be a pico base station for pico cell 102b, and BS110c can be a femto base station for femto cell 102c. A base station can support one or more (e.g., three) cells.

[0070] In some examples, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base station 110 may be interconnected with each other or with one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0071] Wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., base station 110 or UE 120) and send data to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 that can relay transmissions used by other UEs 120. Figure 1 In the example shown, BS110d (e.g., a relay base station) can communicate with BS110a (e.g., a macro base station) and UE 120d to facilitate communication between BS110a and UE 120d. The base station 110 relaying the communication can be referred to as a relay station, relay base station, or repeater.

[0072] Wireless network 100 can be a heterogeneous network, comprising different types of base stations 110, such as macro base stations, pico base stations, femto base stations, or relay base stations. These different types of base stations 110 may have different transmit power levels, different coverage areas, or different effects on interference in wireless network 100. For example, macro base stations may have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0073] Network controller 130 may be coupled to or communicate with a set of base stations 110, and may provide coordination and control for these base stations 110. Network controller 130 may communicate with base stations 110 via a backhaul communication link. Base stations 110 may communicate with each other directly or indirectly via wireless or wired backhaul communication links. In some respects, base station 110 (such as a gNB) or network controller 130 may be referred to herein as a control node.

[0074] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, or a subscriber unit. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, or a satellite radio transceiver), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0075] Some UEs 120 may be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC UEs or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices, or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered Customer Premises Equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components or memory components. In some examples, the processor components and memory components may be coupled together. For example, processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, or electrically coupled.

[0076] Typically, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology or air interface. A frequency can be referred to as a carrier or frequency channel. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0077] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), or mesh networks. In such examples, UEs 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by base station 110.

[0078] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, or channels by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been designated as frequency range names FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, although FR2 is different from the Extremely High Frequency (EHF) band (30GHz-300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU), FR2 is often (interchangeably) referred to as the “millimeter wave” band in documents and articles.

[0079] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has designated the operating bands of these mid-band frequencies as the frequency range name FR3 (7.125GHz-24.25GHz). Bands falling within FR3 can inherit FR1 or FR2 characteristics, and thus can effectively extend the features of FR1 or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation above 52.6GHz. For example, three higher operating bands have been designated as the frequency range names FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz), and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0080] In light of these examples, unless otherwise specifically stated, it should be understood that the term "sub-6 GHz" (if used herein) can broadly refer to frequencies that may be below 6 GHz, frequencies that may be within FR1, or frequencies that may include intermediate frequency bands. Furthermore, unless otherwise specifically stated, it should be understood that the term "millimeter wave" (if used herein) can broadly refer to frequencies that may include intermediate frequency bands, frequencies that may be within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies that may be within the EHF band. It is conceivable that frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0081] In some aspects, a transmitter wireless node (such as UE 120 or base station 110 or one or more other nodes described herein) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may transmit a first SSB in a first duplex mode with a first transmit power configuration associated with the first duplex mode; and transmit a second SSB in a second duplex mode with a second transmit power configuration different from the first transmit power configuration and associated with the second duplex mode. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0082] In some respects, the receiver wireless node (such as UE 120 or base station 110 or one or more other nodes described herein) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive an SSB using a transmit power configuration associated with the SSB's duplex mode; and perform measurements or reports regarding the SSB. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0083] Figure 2 This is a schematic diagram of example 200 of base station 110 communicating with UE 120 in wireless network 100. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0084] At base station 110, transmitting processor 220 can receive data for UE 120 (or a set of UEs 120) from data source 212. Transmitting processor 220 can use one or more Channel Quality Indicators (CQIs) received from UE 120 to select one or more Modulation and Coding Schemes (MCSs) for UE 120. UE 120 can use the MCS selected for UE 120 to process (e.g., encode and modulate) the data for UE 120 and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Partitioning Information (SRPI)) and control information (e.g., CQI requests, grants, or upper-layer signaling) and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., Cell-Specific Reference Signal (CRS) or Demodulation Reference Signal (DMRS)) and synchronization signals (e.g., Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, or up-convert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0085] At UE 120, antenna set 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 or other base stations 110, and can provide a set of received signals (e.g., R received signals) to modem set 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control and system information to the controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Reference Signal Received Power (RSRP) parameter, the Received Signal Strength Indicator (RSSI) parameter, the Reference Signal Received Quality (RSRQ) parameter, or the CQI parameter. In some examples, one or more components of the UE 120 may be included within a housing.

[0086] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0087] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include, or be included therein, one or more antenna panels, one or more antenna groups, one or more antenna element sets, or one or more antenna arrays. Antenna panels, antenna groups, antenna element sets, or antenna arrays may include, or be coupled to, one or more antenna elements (within a single housing or multiple housings), coplanar antenna element sets, non-coplanar antenna element sets, or antennas coupled to one or more transmitting or receiving components (such as…). Figure 2 One or more antenna elements (one or more components).

[0088] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, or CQI). Transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-decoded by TX MIMO processor 266 where applicable, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, modem 254 of UE 120 may include modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the processes described herein.

[0089] At base station 110, uplink signals from UE 120 or other UEs can be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the processes described herein.

[0090] In some implementations, the controller / processor 280 may be a component of a processing system. A processing system can generally refer to a system or a series of machines or components that receive input and process it to produce a set of outputs (which may be passed to, for example, other systems or components of UE 120). For example, the processing system of UE 120 may refer to a system that includes various other components or sub-components of UE 120.

[0091] The processing system of UE 120 can interface with other components of UE 120 and can process information received from other components (such as inputs or signals), output information to other components, etc. For example, the chip or modem of UE 120 may include a processing system and one or more interfaces, such as a first interface for receiving or acquiring information and a second interface for outputting, transmitting, or providing information. In some cases, the first interface may refer to the interface between the processing system of the chip or modem and the receiver, which allows UE 120 to receive information or signal input, and this information can be passed to the processing system. In some cases, the second interface may refer to the interface between the processing system of the chip or modem and the transmitter, which allows UE 120 to transmit information output from the chip or modem. Those skilled in the art will readily recognize that the second interface can also acquire or receive information or signal input, and the first interface can also output, transmit, or provide information.

[0092] In some implementations, the controller / processor 240 may be a component of a processing system. A processing system can generally refer to a system or a series of machines or components that receive input and process it to produce a set of outputs (which may be passed to other systems or components, such as base station 110). For example, the processing system of base station 110 may refer to a system that includes various other components or sub-components of base station 110.

[0093] The processing system of base station 110 can interface with other components of base station 110 and can process information (such as inputs or signals) received from other components, output information to other components, etc. For example, the chip or modem of base station 110 may include a processing system and one or more interfaces, such as a first interface for receiving, acquiring, or selecting information and a second interface for outputting, transmitting, or providing information. In some cases, the first interface may refer to the interface between the processing system of the chip or modem and the receiver, which allows base station 110 to receive information or signal input, and the information may be transmitted to the processing system. In some cases, the second interface may refer to the interface between the processing system of the chip or modem and the transmitter, which allows base station 110 to transmit information output from the chip or modem. Those skilled in the art will readily recognize that the second interface can also acquire or receive information or signal input, and the first interface can also output, transmit, or provide information.

[0094] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 or Figure 2 Any other component may perform one or more techniques associated with SSB transmit power adjustment, as described in more detail elsewhere in this document. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, or... Figure 2 Any other component (or combination of components) can perform or direct, for example Figure 10 Process 1000 Figure 11 The operation of process 1100 or other processes as described herein. Memory 242 and memory 282 may store data and program code for base station 110 and UE 120, respectively. In some examples, memory 242 and memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 or UE 120 (e.g., directly or after compilation, transformation, or interpretation), may cause one or more processors, UE 120, or base station 110 to perform or direct, for example... Figure 10 Process 1000 Figure 11 The operation of process 1100 or other processes as described herein. In some examples, execution instructions may include run instructions, transform instructions, compile instructions, or interpret instructions.

[0095] although Figure 2The boxes in the reference box are shown as different components, but the functionality described by the reference box can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functionality described by the reference transmitter 264, receiver 258, TX MIMO processor 266, or another processor can be performed by or under the control of the controller / processor 280.

[0096] Figure 3 This is a schematic diagram 300 illustrating an example of a radio access network (RAN). As shown by reference numeral 305, a conventional radio access network (RAN) (such as 3G, 4G, LTE, 5G, etc.) may include multiple base stations 310 (shown as access nodes (AN)), each base station 310 communicating with the core network via a wired backhaul link 315 (such as a fiber optic connection). Base station 310 may communicate with UE 320 via access link 325, which may be a radio link. In some aspects, Figure 3 The base station 310 shown can be Figure 1 The base station 110 shown. In some respects, Figure 3 The UE 320 shown can be Figure 1 The UE 120 shown.

[0097] As shown in reference numeral 330, the radio access network (RAN) may include a radio backhaul network, sometimes referred to as an integrated access and backhaul (IAB) network. In the IAB network, at least one base station is an anchored base station 335 that communicates with the core network via a wired backhaul link 340 (such as a fiber optic connection). The anchored base station 335 may also be referred to as an IAB provider (or IAB-provider). The IAB network may include one or more non-anchored base stations 345, sometimes referred to as relay base stations or IAB nodes (or IAB-nodes). Non-anchored base stations 345 may communicate directly or indirectly with the anchored base station 335 via one or more backhaul links 350 (such as via one or more non-anchored base stations 345) to form a backhaul path to the core network for carrying backhaul services. The backhaul link 350 may be a radio link. The anchored base station 335 and non-anchored base station 345 may communicate with one or more UEs 355 via an access link 360, which may be a radio link for carrying access services. In some aspects, Figure 3 The anchored base station 335 or the non-anchored base station 345 shown can be Figure 1 The base station 110 shown. In some respects, Figure 3 The UE 355 shown can be Figure 1 The UE 120 shown.

[0098] As shown in reference numeral 365, in some aspects, radio access networks, including IAB networks, can utilize millimeter-wave technology or directional communication (such as beamforming) for communication between base stations and UEs (i.e., between two base stations, between two UEs, or between a base station and a UE). For example, a radio backhaul link 370 between base stations can use millimeter-wave signals to carry information and can be oriented towards a target base station using beamforming. Similarly, a radio access link 375 between a UE and a base station can use millimeter-wave signals and can be oriented towards a target radio node (such as a UE or a base station) using beamforming. In this way, inter-link interference can be reduced.

[0099] Some of the techniques described in this paper enable SSB transmission using transmit power configurations associated with the duplex mode of the transmitter or receiver radio node of the SSB. For example, some IAB networks can use FD communication to increase throughput and improve resource utilization. FD communication presents certain challenges, such as self-interference, compliance with transmit power limits during transmission, and maintaining acceptable SINR at the receiver radio node operating in FD mode. By configuring the SSB with different transmit power configurations associated with different duplex modes, the FD communication performance of the transmitter radio node (such as anchored base station 335 or non-anchored base station 345) and the receiver radio node (such as non-anchored base station or UE 355) can be improved.

[0100] Figure 3 The configuration of the base station and UE in the example is shown, and other examples can be envisioned. For example, Figure 3 The one or more base stations shown can be replaced by one or more UEs communicating via a UE-to-UE access network (such as a peer-to-peer network or a device-to-device network). In this case, "anchor node" can refer to a UE that communicates directly with a base station (such as an anchored base station or a non-anchored base station).

[0101] Figure 4 This is a schematic diagram 400 illustrating an example of an IAB network architecture. (See diagram 400.) Figure 4 As shown, the IAB network may include an IAB provider 405 (shown as an IAB-provider) connected to the core network via a wired connection (shown as a wired backhaul). For example, the Ng interface of the IAB provider 405 may terminate at the core network. Additionally or alternatively, the IAB provider 405 may connect to one or more devices of the core network providing core access and mobility management functions (AMF). In some aspects, the IAB provider 405 may include a base station 110, such as an anchored base station, as combined with... Figure 3As described herein, the IAB provider 405 may include a central unit (CU) (also referred to herein as a central node) that can perform Access Node Controller (ANC) and AMF functions. The CU may configure one or more Distributed Units (DUs) of the IAB provider 405 and may configure one or more IAB nodes 410 (such as Mobile Terminal (MT) units or DUs of IAB node 410) connected to the core network via the IAB provider 405. In some aspects, the CU may handle the configuration of sets of SSBs with different transmit power configurations, resource configurations for DUs or MTs, or other configurations described herein. Therefore, the CU of the IAB provider 405 can control and configure the entire IAB network connected to the core network via the IAB provider 405, such as through the use of control messages and configuration messages (such as Radio Resource Control (RRC) configuration messages or F1 Application Protocol (F1AP) messages). In some aspects, one or more DUs may include Open RAN (O-RAN) DUs and O-RAN Radio Units (RUs), as described herein. In some aspects, the CU may be referred to herein as a control node.

[0102] In some respects, the IAB network architecture can support O-RAN operability. O-RAN provides hardware and software de-convergence, as well as the interface between them. In some aspects, O-RAN can use an architecture with a CU (such as the CU of the IAB Main 405), one or more DUs (which may be referred to as O-RAN DUs or O-DUs), and one or more RUs (which may be referred to as O-RAN RUs or O-RUs). RUs can perform digital front-end functions, some physical layer functions, digital beamforming, etc. DUs can handle RLC, Media Access Control (MAC), and some physical (PHY) layer functions. CUs can handle certain gNB functions, such as user data delivery, mobility control, RAN sharing, location, session management, etc. A CU can control the operation of one or more DUs, and one or more DUs can control the operation of one or more RUs.

[0103] In some aspects, the CU can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal and communicate with other control functions hosted by the CU. The CU can be configured to handle user plane functions (i.e., Central Unit-User Plane (CU-UP)), control plane functions (i.e., Central Unit-Control Plane (CU-CP)), or combinations thereof. In some implementations, the CU can be logically partitioned into one or more CU-UP units and one or more CU-CP units. The CU can be implemented to communicate with the DU as needed for network control and signaling.

[0104] A DU can correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs. In some aspects, a DU can at least partially depend on lower-layer functional partitioning to host one or more of the RLC layer, MAC layer, and one or more high PHY layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.). Each layer (or module) can be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU or with control functions hosted by the CU.

[0105] Lower-level functions can be implemented by one or more RUs. In some deployments, an RU controlled by a DU can correspond to a logical node of radio frequency processing functions or low-PHY layer functions managed based on lower-level function segmentation (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, etc.) or both. In such an architecture, the RU can be implemented to handle over-the-air (OTA) communications with the UE 120. In some implementations, the real-time and non-real-time aspects of control and user plane communications with the RU can be controlled by the corresponding DU. In some scenarios, this configuration allows the DU and CU to be implemented in a cloud-based RAN architecture (such as a Virtual RAN (VRAN) architecture).

[0106] like Figure 4As further shown, the IAB network may include IAB nodes 410 (shown as IAB-Node 1, IAB-Node 2, and IAB-Node 3) connected to the core network via IAB provider 405. As illustrated, IAB node 410 may include MT functionality (sometimes referred to as UE functionality (UEF)) and may include DU functionality (sometimes referred to as Access Node Function (ANF)). The MT functionality of IAB node 410 (referred to as a child node) may be controlled and scheduled by another IAB node 410 (referred to as the parent node of the child node) or by IAB provider 405. The DU functionality of IAB node 410 (the parent node) may control and schedule other IAB nodes 410 (child nodes of the parent node) and UE 120. Therefore, DU may be referred to as a scheduling node or scheduling component, and MT may be referred to as a scheduled node or scheduled component. In some aspects, IAB provider 405 may include DU functionality but not MT functionality. That is, IAB provider 405 may configure, control, and schedule communication between IAB node 410 and UE 120. UE120 may include only MT functionality without DU functionality. That is, the communication of UE120 can be controlled and scheduled by IAB master 405 or IAB node 410 (such as the parent node of UE120).

[0107] When the first node controls and schedules communication for the second node (such as when the first node provides DU functionality for the second node's MT function), the first node can be referred to as the parent node of the second node, and the second node can be referred to as the child node of the first node. The child node of the second node can be referred to as the grandchild node of the first node. Therefore, the parent node's DU functionality can control and schedule the communication of the parent node's child nodes. The parent node can be IAB Master 405 or IAB Node 410, and the child node can be IAB Node 410 or UE 120. The communication of the child node's MT function can be controlled and scheduled by the child node's parent node.

[0108] like Figure 4 As further shown in Figure 4, the link between UE 120 (which only has MT functionality and not DU functionality) and IAB provider 405, or between UE 120 and IAB node 410, can be referred to as access link 415. Access link 415 can be a radio access link that provides radio access to the core network to UE 120 via IAB provider 405 and optionally via one or more IAB nodes 410. Therefore, the network shown in Figure 4 can be referred to as a multi-hop network or a wireless multi-hop network.

[0109] like Figure 4As further shown, the link between IAB provider 405 and IAB node 410, or between two IAB nodes 410, can be referred to as backhaul link 420. Backhaul link 420 can be a wireless backhaul link that provides radio access to the core network to IAB node 410 via IAB provider 405 and optionally via one or more other IAB nodes 410. In the IAB network, network resources (such as time resources, frequency resources, and spatial resources) used for wireless communication can be shared between access link 415 and backhaul link 420. In some aspects, backhaul link 420 can be a primary backhaul link or a secondary backhaul link (also called a backup backhaul link). In some aspects, a secondary backhaul link can be used if the primary backhaul link fails, becomes congested, or becomes overloaded. For example, if the primary backhaul link between IAB node 2 and IAB node 1 fails, a backup link between IAB node 2 and IAB node 3 can be used for backhaul communication. As used herein, "node" or "wireless node" may refer to IAB Master 405 or IAB Node 410, as well as other examples described elsewhere in this document.

[0110] In some respects, IAB node 410 (the parent node) may not be able to communicate with another IAB node 410 (the child node) using a direct access link. For example, IAB node 2 may be outside the communication range of IAB node 1, or the direct access link between IAB node 1 and IAB node 2 may be blocked. IAB node 1 can use a remote unit (RU) node 425 (such as a relay node or repeater node) to communicate with IAB node 2. IAB node 1 (i.e., the DU of IAB node 1) can use the fronthaul link 430 to communicate with RU node 425. For example, IAB node 1 can use the fronthaul link 430 to send communication to RU node 425. RU node 425 can use the access link 415 between IAB node 2 and RU node 425 to forward communication to IAB node 2. In this way, when IAB-Node 1 cannot use the direct access link between IAB-Node 1 and IAB-Node 2 for direct communication, IAB-Node 1 can extend its coverage and communicate with IAB-Node 2. Some of the techniques described herein enable the configuration and transmission of SSBs using different transmit power configurations, such as to improve performance and facilitate successful communication in different duplex modes.

[0111] Figure 5 This is a schematic diagram 500 illustrating an example of a synchronization signal (SS) hierarchy. For example... Figure 5As shown, the SS hierarchy may include an SS burst set 505, which may include multiple SS bursts 510, shown as SS burst 0 to SS burst N-1, where N is the maximum number of repetitions of the SS burst 510 that can be transmitted by the base station. As further shown, each SS burst 510 may include one or more SSBs 515, shown as SSB 0 to SSB M-1, where M is the maximum number of SSBs 515 that can be carried by the SS burst 510. In some aspects, different SSBs 515 may be beamformed differently (e.g., transmitted using different beams) and may be used for cell search, cell acquisition, beam management, beam selection (such as part of the initial network access procedure), RRM, radio link monitoring (RLM), or similar operations. Receiver radio nodes (such as UE 120) may perform measurements and reporting of the SSBs 515 associated with these operations. SS burst set 505 can be periodically transmitted by a transmitter radio node (such as base station 110, IAB node, IAB master, TRP, or UE in a sidelink network), such as once every X milliseconds. Figure 5 As shown. In some respects, the SS burst set 505 can have a fixed or dynamic length, in Figure 5 The value is shown as Y milliseconds. In some cases, the SS burst set 505 or SS burst 510 may be referred to as the Discovery Reference Signal (DRS) transmission window or the SSB Measurement Time Configuration (SMTC) window. The SSB 515 can also be used for backhaul discovery, such as using the SSB Transmission Configuration (STC).

[0112] In some aspects, SSB 515 may include resources carrying PSS 520, SSS 525, and Physical Broadcast Channel (PBCH) 530. In some aspects, multiple SSBs 515 (utilizing transmissions on different beams) are included in an SS burst 510, and the PSS 520, SSS 525, and PBCH 530 of each SSB 515 across the SS burst 510 may be identical. In some aspects, a single SSB 515 may be included in an SS burst 510. In some aspects, the length of an SSB 515 may be at least four symbols (such as OFDM symbols), wherein each symbol carries one or more of PSS 520 (occupying one symbol), SSS 525 (occupying one symbol), or PBCH 530 (occupying two symbols). In some aspects, an SSB 515 may be referred to as an SS / PBCH block.

[0113] In some respects, the notation for SSB 515 is consistent, such as... Figure 5As shown. In some respects, the symbols of SSB 515 are non-coherent. Similarly, in some respects, one or more SSB 515s of SS burst 510 may be transmitted in coherent radio resources (such as coherent symbols) during one or more time slots. Additionally or alternatively, one or more SSB 515s of SS burst 510 may be transmitted in non-coherent radio resources.

[0114] In some aspects, SS burst 510 may have burst periods, and the SSB 515 of SS burst 510 may be transmitted by the transmitting radio node according to the burst periods. In this case, SSB 515 may repeat during each SS burst 510. In some aspects, SS burst set 505 may have burst set period, and thus the SS burst 510 of SS burst set 505 is transmitted by the radio node according to a fixed burst set period. In other words, SS burst 510 may repeat during each SS burst set 505.

[0115] In some aspects, SSB 515 may include an SSB index, which may correspond to a beam used to carry SSB 515. A receiver radio node (such as UE 120, a base station, or an IAB node) may monitor and measure SSB 515 using different receive (Rx) beams during initial network access procedures or cell search procedures. Based on this monitoring and measurement, the receiver radio node may indicate one or more SSB 515s with optimal signal parameters (such as RSRP parameters in some examples) to the transmitter radio node. The transmitter and receiver radio nodes may use one or more indicated SSB 515s to select one or more beams to be used for communication between the transmitter and receiver radio nodes (such as for a random access channel (RACH) procedure). Additionally or alternatively, the receiver radio node may use SSB 515 or the SSB index to determine cell timing for the cell (e.g., the serving cell) through which it receives SSB 515.

[0116] Some SSB 515s can transmit in full-duplex mode, while others can transmit in half-duplex mode. As described elsewhere in this document, full-duplex mode can refer to either the transmitter wireless node performing FD communication or the receiver wireless node performing FD communication. If SSBs are transmitted at the same transmit power, self-interference can occur at the transmitter wireless node operating in FD mode. Additionally, SSB transmission in full-duplex mode can cause the transmitter wireless node to exceed its total transmit power limit because SSBs can be associated with a predetermined transmit power, and some amount of the transmitter wireless node's power budget is being used for another transmission. Furthermore, if all SSBs are transmitted at the same transmit power, the receiver wireless node in FD mode may not receive the SSBs with sufficient signal strength (such as sufficient SINR) for measuring and reporting them. The techniques described herein enable the transmission of SSB 515s using different transmit power configurations (such as different power offsets relative to each other or relative to a baseline). For example, in Figure 5 In this configuration, as indicated by reference numeral 535, a first set of SSBs 515 (including at least SSB index 0) is transmitted at a first transmit power corresponding to the first duplex mode. As indicated by reference numeral 540, a second set of SSBs 515, including at least SSB index 1, is transmitted at a second transmit power corresponding to the second duplex mode. Therefore, the received signal strength at the FD-mode receiver wireless node can be improved, and self-interference or transmit power limitation violations at the FD-mode transmitter wireless node can be reduced.

[0117] Figure 6 This is a schematic diagram 600 illustrating examples of resource types in an IAB network. In an IAB network, resources (sometimes referred to as time resources) can be configured as downlink-only, uplink-only, flexible, or unavailable (sometimes referred to as "unavailable"). For example, these resources can include time resources, frequency resources, spatial resources, or combinations thereof. When a resource is configured as downlink-only for a wireless node, the resource can only be used for downlink communication of the wireless node and not for uplink communication. Similarly, when a resource is configured as uplink-only for a wireless node, the resource can only be used for uplink communication of the wireless node and not for downlink communication. When a resource is configured as flexible for a wireless node, the resource can be used for both downlink and uplink communication of the wireless node. When a resource is configured as unavailable for a wireless node, the resource may not be used for any communication of the wireless node. In some cases, a resource can be configured as a FD resource for a wireless node, meaning that the resource can be used for FD communication of that wireless node.

[0118] Examples of downlink communication include SSBs (such as...) Figure 5The SSB 515, Channel State Information Reference Signal (CSI-RS), Physical Downlink Control Channel (PDCCH) communication, and Physical Downlink Shared Channel (PDSCH) communication are described and illustrated in the text. Examples of uplink communication include PRACH communication, Physical Uplink Control Channel (PUCCH) communication, Physical Uplink Shared Channel (PUSCH) communication, and Sound Reference Signal (SRS).

[0119] In IAB networks, resources configured as downlink-only, uplink-only, or flexible can also be configured as hard or soft resources. Hard resources are resources that are always available for communication by a given wireless node. Soft resources are conditionally available to a wireless node based on signaling from its parent node. From the perspective of a given wireless node, a given resource is configured as either hard or soft. For example, a given resource could be a hard resource for one wireless node (such as a parent node) and a soft resource for another wireless node (such as a child node of the parent node).

[0120] When a resource is configured as a hard resource for a wireless node, that resource is always available for the wireless node's communication. For example, a hard downlink-only resource is always available only for the wireless node's downlink communication, a hard uplink-only resource is always available only for the wireless node's uplink communication, and a hard flexible resource is always available for both uplink and downlink communication of the wireless node.

[0121] When a resource is configured as a soft resource for a wireless node, its availability is controlled by the wireless node's parent node. For example, the parent node can (explicitly or implicitly) indicate whether the soft resource is available for the wireless node's communication. Therefore, a soft resource can be in one of two states: a schedulable state (when the soft resource is available for scheduling or the wireless node's communication) and an unschedulable state (when the soft resource is neither available for scheduling nor for the wireless node's communication).

[0122] For example, when a wireless node's parent node indicates that soft-only downlink resources are available, these resources can only be used for the wireless node's downlink communication. Similarly, when a wireless node's parent node indicates that soft-only uplink resources are available, these resources can only be used for the wireless node's uplink communication. When a wireless node's parent node indicates that soft-flexible resources are available, these resources can only be used for both uplink and downlink communication.

[0123] As an example, and as shown in reference numeral 605, a resource can be configured to be hard-accessible to child nodes and unavailable to the parent node of the child nodes. In this case, the parent node cannot use the resource for communication, but the child nodes can schedule communication within the resource or use the resource for communication. This configuration can reduce interference between parent and child nodes and can reduce scheduling conflicts between parent and child nodes.

[0124] As another example, and as shown in reference numeral 610, a resource can be configured to be unavailable to child nodes and can be configured to be hard, soft, or unavailable to the parent node (depending on network configuration, network conditions, or the configuration of the parent node's parent node). In this case, the child node cannot schedule communication in that resource and cannot use the time resource for communication.

[0125] As another example, and as shown in reference numeral 615, a resource can be configured to be soft for child nodes and hard, soft, or unavailable for the parent node (depending on network configuration, network conditions, or the configuration of the parent node's parent). In this case, the child node cannot use the resource for scheduling or communication unless it receives an indication from the parent node (explicitly or implicitly) that the resource is available (i.e., released) for use by the child node (a release indication). If the child node receives such an indication, it can schedule communication within the resource or use the resource for communication.

[0126] The configuration of resources as hard / soft / unavailable or uplink / downlink / flexible / FD may be referred to as resource configuration in this document (although "resource configuration" may also refer to other types of configurations as described elsewhere in this document). In some cases, an SSB set (which may be configured with a transmit power configuration indicating a power offset) may be associated with a resource set based on the resource configuration of the resource set. For example, if an SSB is to be transmitted on a resource with a resource configuration associated with a transmit power configuration (such as configured with a transmit power configuration), or overlaps with a resource with a resource configuration associated with a transmit power configuration (such as configured with a transmit power configuration), the transmitter radio node may use the transmit power configuration to transmit the SSB.

[0127] Figure 7 This is a schematic diagram illustrating examples of FD regions, non-FD regions, and self-interference associated with FD communication. As shown, example 700 includes BSs (such as BS110, ...). Figure 3The base station 335 or 345 or transmitter radio node), UE1 (such as UE 120, the MT or receiver radio node of the IAB node), and UE2 (such as UE 120, the MT or receiver radio node of the IAB node). In some aspects, the BS is capable of performing FD communication. FD communication may include simultaneous uplink and downlink communication using the same resources. For example, the BS may perform downlink (DL) transmissions to UE1 (shown by reference numeral 710) and may receive uplink (UL) transmissions from UE2 (shown by reference numeral 720) using the same frequency resources and with at least partial overlap in time.

[0128] In one example, the FD BS can configure or schedule uplink signals (such as RACH signals, PUCCH, PUSCH, or probe reference signals) on time resources that overlap with the SSB (such as SSB 515) to be transmitted by the FD BS. In another example, in an IAB network, the DU's SSB can overlap in time with the transmission or reception of a co-located MT.

[0129] As shown in reference numeral 730, DL transmissions from the BS can interfere with UL transmissions to the BS. This can be caused by various factors, such as higher transmit power (compared to UL transmissions) or RF leakage used for DL ​​transmissions. Furthermore, as shown in reference numeral 740, UL transmissions from UE2 to the BS can interfere with DL transmissions from the BS to UE1, thereby degrading the DL performance of UE1.

[0130] FD areas are indicated by reference numeral 750, and non-FD areas are indicated by reference numeral 760. An "FD area" can refer to one or more time periods or frequency regions in which a wireless communication device (such as BS110, UE 120, a wireless node, or similar device) performs FD communication, and a "non-FD area" can refer to one or more time periods or frequency regions in which a wireless communication device performs non-FD communication. Compared to non-FD areas, FD areas can be associated with higher self-interference and therefore with lower SINR. Base stations operating in FD areas may be referred to herein as operating in FD mode, and base stations operating in non-FD areas may be referred to herein as operating in non-FD mode.

[0131] Some receiver radio nodes can operate in FD mode, in which the receiver radio node transmits and receives communications on the same resources. Receiver radio nodes capable of operating in FD mode are said to be FD-capable. For example, a receiver radio node may be capable of both FD mode operation (in which the receiver radio node performs FD communication in an FD area) and HD mode operation (in which the receiver radio node performs only HD communication). Some receiver radio nodes may only be capable of HD mode operation. In some aspects, an SSB set (such as SSB 515) can be configured for duplex modes, such as FD mode at the transmitter radio node, FD mode at the receiver radio node, HD mode at the transmitter radio node, or HD mode at the receiver radio node. For example, one or more of these duplex modes can be configured with an SSB set having a reduced transmit power configuration to reduce self-interference or transmit power limit violations (in an FD area), or an increased transmit power configuration to provide an acceptable SINR for FD receiver radio nodes in an FD area.

[0132] Figure 8 This is a schematic diagram 800 illustrating an example of using an explicitly indicated SSB transmit power configuration. As shown in the diagram, Figure 8 Including receiver wireless node 805 (such as Figure 1 UE 120 or base station 110, TRP, Figure 3 Non-anchored base station 345 or UE355 Figure 4 The MT or DU of the IAB-node 410 Figure 6 The child IAB-node or such Figure 7 The UE depicted in the text) and the transmitter wireless node 810 (such as Figure 1 UE 120 or base station 110, TRP, Figure 3 Anchored base station 355 or non-anchored base station 345, Figure 4 The IAB-supply master 405 or IAB-node 410 DU, Figure 6 The parent IAB-node or such Figure 7 (The described base station). In some aspects, the transmitter wireless node and the receiver wireless node can be UEs and can communicate using sidelink or device-to-device (D2D) protocols. In some aspects, the transmitter wireless node and the receiver wireless node can be IAB nodes (such as IAB-supplier or IAB-node) of an IAB network. In some aspects, the transmitter wireless node and the receiver wireless node can be base stations performing backhaul discovery. In some aspects, the transmitter wireless node can be base station 110, and the receiver wireless node can be UE 120 operating in a radio access network (such as performing uplink and downlink communication).

[0133] As illustrated by reference numeral 815, the receiver wireless node can receive an indication of one or more transmit power configurations for one or more sets of SSBs. As shown, the transmit power configuration may include a power offset for transmission of the SSBs and may indicate the set of SSBs to which the power offset is to be applied. For example, the transmit power configuration may be mapped to a set of SSBs. The power offset may be relative to another SSB or relative to a baseline transmit power. In some aspects, the indication of one or more transmit power configurations may indicate an absolute transmit power (such as not using a power offset). The receiver wireless node may use the indication to perform monitoring, measurement, or reporting of received SSBs, as described elsewhere herein. In some aspects, the receiver wireless node may determine the indication. “Obtaining an indication” may mean receiving an indication, determining an indication, identifying an indication, or selecting an indication.

[0134] exist Figure 8 In the example, the receiver radio node receives an indication from the transmitter radio node, which is the node that will transmit one or more SSBs according to one or more transmit power configurations. In some other respects, the receiver radio node may receive the indication from a control node (such as a gNB, a DU that configures the transmitter radio node and the MT of the receiver radio node, or (if the radio node communicating is a UE) a UE or a roadside unit). The receiver radio node may receive the indication via Residual Minimal System Information (RMSI) (such as via System Information Block 1 (SIB1)), SIBs other than SIB1, Dedicated Radio Resource Control (RRC) signaling, group common messages (such as downlink control information), Function Division (F1) interface messages, STC associated with backhaul discovery, Dedicated Downlink Control Information, or another form of signaling.

[0135] In some respects, a wireless node can receive indications via a backhaul connection. For example, a transmitter wireless node's DU can receive indications (or transmit power configurations) for a set of SSBs, such as via a logical interface between the DU and the CU. In some respects, a DU (such as a transmitter wireless node's DU) can provide indications to the CU. For example, a DU can indicate one or more selected transmit power configurations (selected by the DU) for one or more sets of SSBs.

[0136] This instruction can define one or more SSB sets. Figure 8In the example, the instruction defines two SSB sets. For example, SSB sets can be explicitly defined. For example, the instruction may include one or more SSB bitmaps. A bitmap for an SSB set may include multiple bits corresponding to multiple SSBs. Bits set to a first value may indicate that the corresponding SSB (such as the corresponding SSB index) belongs to the SSB set, and bits set to a second value may indicate that the corresponding SSB does not belong to the SSB set. In some aspects, the instruction may include a bitmap for each SSB set defined by the instruction. In some aspects, the bitmap may have a size equal to the total number of SSB candidates within the SS burst set (such as L). max The value of the bitmap can be based on the carrier frequency or frequency band. For example, the bitmap can include L. max 1 bit. In some other respects, the bit mapping can have a size equal to the number of SSBs transmitted or the configured number of SSBs. For example, in some cases, the transmitter wireless node can transmit fewer than L bits. max There are 10 SSBs. In this case, the bit mapping may include a number of bits equal to the number of SSBs to be transmitted in the SS burst set. In some aspects, the indication may include information identifying the set of SSB indices. For example, the indication may explicitly identify each SSB index that will be included in the SSB set.

[0137] As further illustrated, the SSB set can be associated with a duplex mode. In some aspects, the indication can specify the duplex mode. For example, the indication can instruct a transmitter wireless node operating in a given duplex mode, or a transmitter wireless node transmitting an SSB for a receiver wireless node operating in a given duplex mode, to use a given transmit power configuration to transmit the SSB. In this example, the transmitter wireless node can determine which transmit power configuration to use for the SSB based on the duplex mode. In some other aspects, the indication can not explicitly specify the duplex mode. For example, the transmitter wireless node can transmit an SSB belonging to the SSB set with the corresponding transmit power configuration, regardless of which duplex mode the transmitter or receiver wireless node is using.

[0138] The duplex mode can include, for example, an HD mode (as associated with transmitting SSBs in HD mode), a transmitter-side FD mode (as associated with transmitting SSBs in FD mode at the transmitter radio node), a receiver-side FD mode (as associated with transmitting SSBs in FD mode to be received by the receiver radio node), and an IAB mode (where resources for transmitting SSBs by the DU overlap with resources for communication by the co-located MT). As mentioned, different sets of SSBs can be configured for different duplex modes.

[0139] In some implementations, the transmit power configuration can provide increased transmit power for SSBs transmitted to FD-enabled receiver radio nodes (such as FD UEs). Therefore, the SSB can achieve the SINR required for successful SSB reception at the receiver radio node. In other implementations, the transmit power configuration can provide reduced transmit power for SSBs transmitted by FD-enabled transmitter radio nodes. Therefore, self-interference at the transmitter radio node can be reduced, and the total transmit power limit of the transmitter radio node can be met.

[0140] Reference numeral 820 illustrates SSB transmission when one or more of the receiver or transmitter wireless nodes are in a first duplex mode. The first duplex mode may include, for example, HD mode, transmitter-side FD mode, receiver-side FD mode, IAB mode, or another form of mode. In some aspects, the duplex mode may be based on whether SSBs are transmitted in the FD zone (of the transmitter or receiver wireless node). Figure 9 Some aspects illustrated and described involve the duplex mode based on the resource configuration of resources used to send SSBs or resources that overlap with resources used to send SSBs.

[0141] As shown by reference numeral 825, the transmitter wireless node can transmit SSBs according to a transmit power configuration. For example, the transmit power configuration can be based on a first SSB set associated with a first duplex mode using a power offset (power offset 1) configured for the first SSB set. As shown by reference numeral 830, the receiver wireless node can measure SSBs based on the transmit power configuration. For example, for beam management, RLM, RRM, etc., the receiver wireless node can assume an adjusted transmit power (defined by power offset 1). If measurements based on multiple SSB instances with different transmit power configurations are to be combined (e.g., for filtering purposes), the receiver wireless node can adjust (e.g., normalize) the measurements of the multiple SSB instances according to the different transmit power configurations. In some aspects, if an SSB has an adjusted transmit power below a threshold, the receiver wireless node can skip the reception of the SSB during an evaluation period used for measurement or reporting. In such an example, the length of the evaluation period can be extended. For example, the length of the evaluation period can be extended based on how many measurement opportunities to skip (e.g., by a factor of 2, 3, or another factor).

[0142] Reference numeral 835 illustrates SSB transmission when one or more of the receiver or transmitter wireless nodes are in a second duplex mode. The second duplex mode may include, for example, HD mode, transmitter-side FD mode, receiver-side FD mode, IAB mode, or another form of mode. In some aspects, the duplex mode may be based on whether SSBs are transmitted in the FD zone (of the transmitter or receiver wireless node).

[0143] As shown by reference numeral 840, the transmitter wireless node can transmit another SSB based on the transmit power configuration. For example, the transmit power configuration can be based on a second SSB set associated with a second duplex mode using a power offset (power offset 2) configured for the second SSB set. As shown by reference numeral 845, the receiver wireless node can measure the SSB based on the transmit power configuration. For example, for beam management, RLM, RRM, etc., the receiver wireless node can assume an adjusted transmit power (defined by power offset 2). If measurements based on multiple SSB instances with different transmit power configurations are to be combined (e.g., for filtering purposes), the receiver wireless node can adjust (e.g., normalize) the measurements of the multiple SSB instances based on the different transmit power configurations. In some aspects, if an SSB has an adjusted transmit power below a threshold, the receiver wireless node can skip the reception of the SSB during the evaluation period. In such an example, the receiver wireless node can extend the length of the evaluation period.

[0144] As shown by reference numeral 850, the receiver radio node can perform measurements or reports regarding one or more SSBs. For example, the receiver radio node can perform measurements as described with respect to reference numerals 830 and 845. As another example, the receiver radio node can send a report indicating beam fault detection. As yet another example, the receiver radio node can send a report indicating a selected beam for beam fault recovery. As yet another example, the receiver radio node can send an indication of radio link fault, radio link quality, synchronization / desynchronization indication, or similar messages. As yet another example, the receiver radio node can select a suitable cell for camping, perform cell reselection, perform inactive mobility control, or similar operations. As yet another example, the receiver radio node or transmitter radio node can perform handover, RRC reconstruction, RRC connection release with redirection, or similar operations.

[0145] Figure 9 This is a schematic diagram 900 illustrating an example of an SSB transmit power configuration using implicit indication. As shown in the diagram, Figure 9 Including receiver wireless node 905 (such as Figure 1 UE 120 or base station 110 Figure 3Non-anchored base station 345 or UE 355, Figure 4 The MT or DU of the IAB-node 410 Figure 6 The child IAB-node or such Figure 7 The UE described in the document and the transmitter wireless node 910 (such as...) Figure 1 UE 120 or base station 110 Figure 3 Anchored base station 335 or non-anchored base station 345, Figure 4 The IAB-supply master 405 or IAB-node 410 DU, Figure 6 The parent IAB-node or such Figure 7 (The base station described herein). In some aspects, the transmitter wireless node and the receiver wireless node may be UEs and may communicate using sidelinks or device-to-device protocols. In some aspects, the transmitter wireless node and the receiver wireless node may be IAB nodes (such as IAB-supplier or IAB-node) of an IAB network. In some aspects, the transmitter wireless node and the receiver wireless node may be base stations performing backhaul discovery. In some aspects, the transmitter wireless node may be base station 110, and the receiver wireless node may be UE 120 of a radio access network (such as performing uplink and downlink communication).

[0146] As illustrated by reference numeral 915, a transmitter wireless node can provide an indication of one or more transmit power configurations (such as one or more power offsets) for one or more sets of SSBs. For example, this indication can specify the transmit power configuration and can map the transmit power configuration to sets of SSBs. Figure 9 In the example, the SSB set can be defined based on resource configuration. For instance, the indication (or other information) can indicate a specific resource configuration, and SSBs that satisfy that specific resource configuration can belong to the SSB set associated with that specific resource configuration. In this case, the indication can indicate a transmit power configuration (such as power offset) and the corresponding resource configuration for the SSBs to utilize that transmit power configuration.

[0147] As shown by reference numeral 920, a receiver radio node can receive information indicating resource configurations for communication between the receiver radio node and the transmitter radio node. In some aspects, the receiver radio node can receive this information from the transmitter radio node, as shown. In some other aspects, the receiver radio node can receive this information from another node (such as a CU). In some aspects, resource configurations may include Time Division Duplex (TDD) configurations (such as the TDDconfigCommon parameter), dedicated TDD configurations, or cell-specific TDD configurations. In some aspects, resource configurations may include Slot Format Indication (SFI) configurations. In some aspects, resource configurations may include IAB DU resource configurations (which may configure resources as hard / soft / unavailable, or may indicate the TDD mode for IAB DU resources). In some aspects, resource configurations may indicate combinations of these configurations for one or more resources.

[0148] As illustrated by reference numerals 925 and 930, the receiver wireless node and the transmitter wireless node can identify one or more sets of SSBs based on resource configuration. For example, the receiver wireless node or the transmitter wireless node can determine that the resources used to transmit (or receive) the SSB have a specific resource configuration identified by the indication, or it can determine that the resources used to transmit (or receive) the SSB overlap with resources having a specific resource configuration identified by the indication.

[0149] As an example, this instruction can indicate that an SSB overlapping with downlink resources belongs to a specific set of SSBs. As another example, this instruction can indicate that an SSB overlapping with uplink resources belongs to a specific set of SSBs. As yet another example, this instruction can indicate that an SSB overlapping with flexible resources belongs to a specific set of SSBs. As yet another example, this instruction can indicate that an SSB overlapping with full-duplex or bidirectional resources can belong to a specific set of SSBs.

[0150] In some respects, such as for IAB networks, this indication may specify that SSBs within hard resources, unavailable resources, and soft resources can be associated with different sets of SSBs. Additionally or alternatively, SSBs on resources overlapping with resources allocated to a parent or child IAB-node of a transmitter radio node may be assigned to a first set of SSBs, and SSBs within resources specifically allocated to a transmitter radio node may be assigned to a second set of SSBs.

[0151] In some respects, resource configuration can indicate the configured communication resources. For example, resource configuration can be a semi-static (such as RRC) configuration of the configured communication. As just one example, resource configuration can indicate the RACH timing (RO) associated with sending RACH messages for the RACH procedure. In some respects, SSBs that overlap with the configured communication resources can be associated with a specific set of SSBs.

[0152] As shown by reference numeral 935, the transmitter wireless node can transmit SSBs using a transmit power configuration associated with a first duplex mode. The transmitter wireless node can also transmit SSBs using a transmit power configuration associated with a first set of SSBs. The transmitter wireless node can determine which transmit power configuration to use to transmit SSBs based on the resources of the SSB or the resources of the SSB and their overlapping resources mapped to the first set of SSBs. As shown by reference numeral 940, the receiver wireless node can measure SSBs based on the transmit power configuration associated with the first set of SSBs.

[0153] As shown by reference numeral 945, the transmitter wireless node can transmit another SSB using a transmit power configuration associated with the second duplex mode. The transmitter wireless node can also transmit an SSB using a transmit power configuration associated with a second set of SSBs. The transmitter wireless node can determine which transmit power configuration to use to transmit the SSB based on the resources of the SSB associated with the resource configuration mapped to the second set of SSBs, or resources overlapping with the resources of the SSB. As shown by reference numeral 950, the receiver wireless node can measure the SSB based on the transmit power configuration associated with the second set of SSBs.

[0154] As indicated by reference numeral 955, the receiver wireless node can perform measurements or reports regarding one or more SSBs. For example, the receiver wireless node can perform actions such as regarding... Figure 8 Reference numbers 830 and 845 or about Figure 9The measurements described in reference figures 940 and 950. As another example, the receiver radio node can send a report indicating beam fault detection. As yet another example, the receiver radio node can send a report indicating a selected beam for beam fault recovery. As yet another example, the receiver radio node can send an indication of radio link fault, radio link quality, synchronization / desynchronization, or similar messages. As yet another example, the receiver radio node can select a suitable cell for camping, perform cell reselection, perform inactive mobility control, or similar operations. As yet another example, the receiver radio node or transmitter radio node can perform handover, RRC reconstruction, RRC connection release using redirection, or similar operations.

[0155] Figure 10 This is a schematic diagram of an example process 1000 performed by a device of a wireless node. Process 1000 is a device of a transmitting wireless node (e.g., Figure 1 UE 120 or base station 110 Figure 3 Anchored base station 335 or non-anchored base station 345, Figure 4 The IAB-supply master 405 or IAB-node 410 DU, Figure 6 The parent IAB node, such as Figure 7 The example described herein is of a base station or transmitter wireless node 910 performing an operation associated with SSB transmit power adjustment.

[0156] like Figure 10 As shown, in some aspects, process 1000 may include, in a first duplex mode, transmitting a first SSB with a first transmit power configuration associated with the first duplex mode, the first transmit power configuration being configured to include the first SSB and a first set of SSBs associated with the first duplex mode (block 1010). For example, apparatus (such as by using...) Figure 12 The communication manager 140, transmitting component 1204, or power control component 1208 depicted herein can transmit the first synchronous SSB with a first transmit power configuration in a first duplex mode. In some aspects, the first transmit power configuration can be associated with the first duplex mode. In some aspects, the first transmit power configuration can be configured to include the first SSB and a first set of SSBs associated with the first duplex mode.

[0157] like Figure 10 As further shown, in some aspects, process 1000 may include transmitting a second SSB in a second duplex mode with a second transmit power configuration different from the first transmit power configuration and associated with the second duplex mode, the second transmit power configuration being configured to include the second SSB and a second set of SSBs associated with the second duplex mode (block 1020). For example, apparatus (such as by using...) Figure 12 The communication manager 140, transmitting component 1204, or power control component 1208 depicted herein can transmit a second SSB in a second duplex mode with a second transmit power configuration. The second transmit power configuration may differ from the first transmit power configuration. In some aspects, the second transmit power configuration may be associated with the second duplex mode. In some aspects, the second transmit power configuration may be configured to include a second SSB set associated with the second duplex mode.

[0158] Process 1000 may include additional aspects, such as any single aspect or any combination of aspects described in conjunction with process 1000 or one or more other processes described elsewhere herein.

[0159] In a first additional aspect, process 1000 includes transmitting information indicating a power offset for a first set of SSBs associated with a first duplex mode, wherein the first transmit power configuration is based on the power offset.
