[0003] Field of Disclosure

[0004] Aspects of the present disclosure generally relate to wireless communication, and more particularly, to techniques and apparatus for beam sweep configurations for wireless nodes with full - duplex capabilities.

[0005] Background

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ multiple - access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc., or a combination thereof). 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 / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the 3rd Generation Partnership Project (3GPP).

[0007] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments (UEs) to communicate at the urban, national, regional, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhanced set of the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrums, and using Orthogonal Frequency Division Multiplexing with Cyclic Prefix (CP-OFDM) on the downlink (DL), CP-OFDM or SC-FDMA (e.g., also referred to as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technology, and carrier aggregation to better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvement in LTE and NR technologies. Preferably, these improvements are applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

[0008] In some frequency bands of some communication systems, wireless nodes use beam sweeping procedures to transmit information to other wireless nodes. For example, a first wireless node may transmit a Synchronization Signal Block (SSB) to provide initial access information to another wireless node. In such examples, by using beam sweeping, the first wireless node achieves wide-angle area coverage when using narrow-angle beams. Other examples of beam sweeping communication may include Remaining Minimum System Information (RMSI) transmission, System Information Block (SIB) transmission, Random Access Channel (RACH) transmission, Channel State Information Reference Signal (CSI-RS) transmission, Sounding Reference Signal (SRS) transmission, etc. Some wireless nodes may have full-duplex capabilities, thereby enabling concurrent transmission and reception in the same frequency. Full-duplex capabilities can increase capacity, reduce latency, reduce resource overhead, and so on. However, due to changing channel conditions, link budgets, available transmit or receive power, relative positions, geographical features (such as during mobility operations), etc., full-duplex capabilities can change over time.

[0031] Detailed Description

[0032] Aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be implemented in many different forms and is not to be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based at least in part on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. Additionally, the scope of the present disclosure is intended to cover such apparatus or methods practiced using other structures, functionality, or a combination of structures and functionality that supplement or are additional to the various aspects of the present disclosure set forth herein. Any aspect of the present disclosure disclosed herein may be implemented by one or more elements of a claim.

[0033] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in detail below and illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc., or combinations thereof (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0034] In full - duplex operation, a wireless communication device or wireless node (e.g., a user equipment (UE), a base station, or an integrated access and backhaul (IAB) node, etc.) may transmit and receive concurrently using the same frequency or frequency band. For example, a wireless node may transmit a first beam to a parent wireless node at a particular frequency and concurrently receive a second beam from a child wireless node at the same frequency. Similarly, the wireless node may receive a first beam from the parent wireless node while concurrently transmitting a second beam to the child wireless node. The full - duplex capability may change over time. For example, a wireless node may support full - duplex communication for a first beam pair at a particular frequency at a first time, but may not support full - duplex communication for a second beam pair at that particular frequency at a second time.

[0035] Aspects generally relate to beam sweep configurations for wireless nodes with full-duplex capabilities. Some aspects more specifically relate to determining full-duplex capabilities for a particular beam pair and selecting or reselecting a beam sweep configuration for full-duplex communication at least in part based on the full-duplex capabilities for the particular beam pair. For example, when configured with full-duplex capabilities, a first beam sweep configuration (such as a first beam width or beam shape) may be selected; when not configured with full-duplex capabilities, a second beam sweep configuration (such as a second beam width or beam shape) may be selected. In some aspects, a particular beam pair may include a transmit beam and a receive beam for communication between two wireless nodes (such as for communication between a parent wireless node and a child wireless node). In some aspects, a wireless communication device or wireless node may determine beam width, beam shape, beam direction, beam order, a set of resources selected for transmission or reception, periodicity for beam sweeping, transmit or receive power, and so on when determining a beam sweep configuration.

[0036] Specific aspects of the subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages. In some examples, the techniques described may be used to implement full-duplex operation for beam sweep communication while accommodating varying full-duplex operating conditions. For example, the wireless node may adapt parameters (such as beam shape, beam order, etc.) such that the likelihood of interference occurring in full-duplex operation can be reduced relative to a static configuration. By enabling full-duplex operation, the wireless node may reduce the overhead associated with beam sweep communication by using full-duplex operation when available.

[0037] Figure 1 is a block diagram illustrating an example wireless network in accordance with various aspects of the present disclosure. The wireless network may be a Long Term Evolution (LTE) network or some other wireless network, such as a 5G or NR network. The wireless network may include a number of base stations (BSs) 110 (shown as BS110a, BS110b, BS110c, and BS 110d) and other network entities. A BS is an entity that communicates with (a) user equipment(s) (UE), and may also be referred to as a B node, evolved B node, eNB, gNB, NR BS, 5G B node (NB), access point (AP), or transmit receive point (TRP), etc., or a combination thereof (these terms are used interchangeably herein). Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to the coverage area of a BS or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0038] A BS can provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell can cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unconstrained access by UEs with service subscriptions. A pico cell can cover a relatively small geographical area and can allow unconstrained access by UEs with service subscriptions. A femto cell can cover a relatively small geographical area (e.g., a residence) and can allow constrained access by UEs associated with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macro cell can be referred to as a macro BS. A BS for a pico cell can be referred to as a pico BS. A BS for a femto cell can be referred to as a femto BS or a home BS. A BS can support one or more (e.g., three) cells.

[0039] The wireless network can be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, or relay BSs, etc., or combinations thereof). These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network. For example, a macro BS can have a high transmit power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts). In Figure 1 the example shown, BS110a can be a macro BS for macro cell 102a, BS110b can be a pico BS for pico cell 102b, and BS110c can be a femto BS for femto cell 102c. The network controller 130 can be coupled to the set of BSs 102a, 102b, 110a, and 110b and can provide coordination and control for these BSs. The network controller 130 can communicate with each BS via a backhaul. These BSs can also communicate with each other directly or indirectly, e.g., via a wireless or wired backhaul.

[0040] In some aspects, a cell can be non-stationary. Instead, the geographical area of the cell can move according to the position of a mobile BS. In some aspects, BSs can be interconnected with each other or with one or more other BSs or network nodes (not shown) in the wireless network via various types of backhaul interfaces such as direct physical connections, or virtual networks, etc., or combinations thereof using any suitable transmission network.

[0041] The wireless network can also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send the transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In Figure 1In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. The relay station may also be referred to as a relay BS, relay base station, or relay, etc., or a combination thereof.

[0042] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network, and each UE can be stationary or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, or station, etc., or a combination thereof. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, a superbook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless medium.

[0043] Some UEs may be considered machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags, etc., or a combination thereof, which can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node can provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) or provide connectivity to the network, for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, or may be implemented as narrowband IoT (NB-IoT) devices. Some UEs may be considered customer premise equipment (CPE). UE 120 can be included inside a housing that houses components of UE 120, such as a processor component, or a memory component, etc., or a combination thereof.

[0044] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies or frequency channels. The frequency may also be referred to as a carrier, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0045] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly with each other using one or more sidelink channels (e.g., without using the base station 110 as an intermediary). For example, the UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, or vehicle-to-infrastructure (V2I) protocols, etc., or combinations thereof), or mesh networks, etc., or combinations thereof. In such examples, the UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as performed by the base station 110.

[0046] Figure 2 is a block diagram illustrating an example base station (BS) in communication with a user equipment (UE) in a wireless network according to various aspects of the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where generally T≥1 and R≥1.

[0047] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCSs) for the UE at least in part based on the channel quality indicator (CQI) received from each UE, process (e.g., encode) the data for the UE at least in part based on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, or upper layer signaling, etc., or combinations thereof), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a-232t. Each MOD 232 may process the corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each MOD 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from MODs 232a through 232t may be transmitted via the T antennas 234a through 234t, respectively. According to various aspects described in more detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0048] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 or other base stations and may provide the received signals to R demodulators (DEMODs) 254a through 254r, respectively. Each DEMOD 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain input samples. Each DEMOD 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain the symbols received from all R DEMODs 254a through 254r, perform MIMO detection on the received symbols when applicable, and provide detected symbols. The receive processor 258 may process (e.g., decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The channel processor may determine a reference signal received power (RSRP), a received signal strength indicator (RSSI), a reference signal received quality (RSRQ), or a channel quality indicator (CQI), etc., or a combination thereof. In some aspects, one or more components of the UE 120 may be included in a housing.

[0049] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for a report including RSRP, RSSI, RSRQ, or CQI, etc., or a combination thereof). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 when applicable, further processed by the MODs 254a through 254r (e.g., for discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM), or orthogonal frequency division multiplexing with a cyclic prefix (CP) (CP-OFDM), etc., or a combination thereof), and transmitted to the base station 110. At the base station 110, the uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the DEMOD 232, detected by the MIMO detector 236 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0050] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, or Figure 2 any other component of may perform one or more techniques associated with beam sweep configuration for a wireless node with full-duplex capability, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, or Figure 2 any other component of may perform or direct operations of, for example, Figure 7 the process of, Figure 8 the process of or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120 respectively. Scheduler 246 may schedule the UE for data transmission on the downlink or uplink.

[0051] In some aspects, a wireless communication device (such as base station 110 or UE 120) may include: means for determining the full-duplex capability of a wireless node for a particular beam pair, means for selecting a beam sweep configuration for full-duplex communication at least in part based on the full-duplex capability of the wireless node for the particular beam pair, means for causing communication to occur according to the beam sweep configuration using the particular beam pair at least in part based on the selection of the beam sweep configuration, and so on, or combinations thereof. In some aspects, such means may include one or more components of base station 110 or UE 120 described in conjunction with Figure 2 .

[0052] Figure 3 illustrates an example logical architecture of a distributed radio access network (RAN) in accordance with various aspects of the present disclosure. A 5G access node 306 may include an access node controller (ANC) 302. The ANC may be a central unit (CU) of the distributed RAN. The backhaul interface to the next generation core network (NG-CN) 304 may terminate at the ANC. The backhaul interface to an adjacent next generation access node (NG-AN) 310 may terminate at the ANC. The ANC may include one or more TRPs 308 (which may also be referred to as BS, NR BS, B node, 5G NB, AP, gNB, or some other term). As described above, "TRP" may be used interchangeably with "cell".

[0053] The TRP 308 may be a distributed unit (DU). The TRP may be connected to one ANC (ANC 302) or more than one ANC (not illustrated). For example, for RAN sharing, radio as a service (RaaS), and service-specific AND deployments, the TRP may be connected to more than one ANC. The TRP may include one or more antenna ports. The TRP may be configured to serve traffic to the UE individually (e.g., dynamic selection) or jointly (e.g., joint transmission).

[0054] The local architecture of the RAN can be used to support the fronthaul definition. This architecture can be defined to support fronthaul solutions across different deployment types. For example, the architecture can be at least partially based on transport network capabilities (e.g., bandwidth, latency, or jitter).

[0055] This architecture can share features or components with LTE. In some aspects, the NG-AN 310 can support dual connectivity with NR. The NG-AN 310 can share a common fronthaul for LTE and NR.

[0056] This architecture can enable cooperation between and among the TRPs 308. For example, cooperation can be preconfigured within a TRP or across TRPs via the ANC 302. In some aspects, an inter-TRP interface may not be required / present.

[0057] In some aspects, there can be a dynamic configuration of split logical functions within the RAN architecture. The Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and MAC protocol layers can be adaptively placed at the ANC or TRP.

[0058] Figure 4 An example physical architecture of a distributed RAN according to various aspects of the present disclosure is illustrated. A Centralized Core Network Unit (C-CU) 402 can host core network functions. The C-CU can be centrally deployed. C-CU functionality can be offloaded (e.g., to Advanced Wireless Services (AWS)) to attempt to handle peak capacity. A Centralized RAN Unit (C-RU) 404 can host one or more ANC functions. Optionally, the C-RU can locally host core network functions. The C-RU can have a distributed deployment. The C-RU can be closer to the network edge. A Distributed Unit (DU) 406 can host one or more TRPs. The DU can be located at the edge of the network with radio frequency (RF) functionality.

[0059] Figures 5A - 5C is a diagram illustrating an example of a network topology for a multi-link network according to various aspects of the present disclosure. Self-backhaul or Integrated Access / Backhaul (IAB) can be deployed to use a common set of resources for access traffic and backhaul traffic. For example, a first node (e.g., BS110, UE 120, etc.) can communicate backhaul traffic with a second node via a first millimeter wave resource and can communicate access traffic with a third node via a second millimeter wave resource. In some aspects, the second node and the third node can be the same node. For example, the first node can communicate traffic via the first millimeter wave resource and the second millimeter wave resource. Although some aspects described herein are described in the form of an IAB deployment, some aspects described herein can be used in conjunction with other types of multi-hop networks.

[0060] As Figure 5A shown, Example 500 may include a plurality of wireless nodes 502 (BS) and a plurality of wireless nodes 504 (UE). At least one wireless node (wireless node 502-1) may communicate with a core network via a backhaul link 506 (such as a fiber optic connection, a wireless backhaul connection, etc.). The wireless nodes 502 and 504 may communicate with each other using: a link set 508 (such as a millimeter wave link set); air interfaces such as 3G, 4G, 5G, etc.; and so on.

[0061] As Figure 5A further shown, one or more of the wireless nodes 502 or 504 may communicate indirectly via one or more other wireless nodes 502 or 504. For example, data may be passed from the core network to wireless node 504-6 via the backhaul link 506, the link 508 between wireless nodes 502-1 and 502-5, the link 508 between wireless nodes 502-5 and 502-4, the link 508 between wireless nodes 502-4 and 504-5, and the link 504 between wireless nodes 504-5 and 504-6. In some aspects, multiple different paths may be used to convey data between the wireless nodes 502 or 504. For example, wireless node 502-5 may communicate with wireless node 502-4 via a single link 508 (direct link) between wireless nodes 502-5 and 502-4, and / or via a first link 508 between wireless nodes 502-5 and 502-3 and a second link (indirect link) between wireless nodes 502-3 and 502-4.

[0062] As Figure 5BAs shown, wireless nodes 502 and 504 can be arranged in a hierarchical topology to achieve management of network resources. Each link 508 can be associated with a primary link endpoint (primary LEP) and a secondary link endpoint (secondary LEP), which can define the hierarchy between wireless nodes 502 or 504. For example, wireless node 502-6 can communicate with wireless node 502-7 via link 508-1. In such an example, wireless node 502-6 is associated with the primary link endpoint of link 508-1, and wireless node 502-7 is associated with the secondary link endpoint of link 508-1, which can define wireless node 502-6 as being superior in the hierarchy to wireless node 502-7 and wireless node 502-7 as being inferior in the hierarchy to wireless node 502-6 with reference to link 508-1. In such an example, wireless node 502-6 can be referred to as the primary wireless node or the parent wireless node, while wireless node 502-7 can be referred to as the secondary wireless node or the child wireless node. Moreover, wireless node 502-6 can be defined as upstream with respect to wireless node 502-7 (while wireless node 502-7 can be defined as downstream with respect to wireless node 502-6).

[0063] Similarly, wireless node 502-7 includes the primary link endpoint of link 508-2, while wireless node 502-8 includes the secondary link endpoint of link 508-2. In such an example, with reference to link 502-2, wireless node 502-7 is superior in the hierarchy to wireless node 502-8 and is upstream of wireless node 502-8, while wireless node 502-8 is inferior in the hierarchy to wireless node 502-7 and is downstream of wireless node 502-7. In such an example, wireless node 502-7 can be referred to as the primary wireless node or the parent wireless node, while wireless node 502-8 can be referred to as the secondary wireless node or the child wireless node.

[0064] As Figure 5C shown, a set of interfaces can be illustrated for a set of wireless nodes 502 in a hierarchical topology. In such an example, wireless node 502-10 (the first IAB wireless node) can be lower in the hierarchy than wireless node 502-11 (the second IAB wireless node), and can be lower in the hierarchy than wireless node 502-12 (the IAB donor). Similarly, wireless node 502-11 can be lower in the hierarchy than wireless node 502-12.

[0065] In some aspects, an IAB wireless node can be a wireless node that relays traffic to or from an anchor via one or more hops (one or more other wireless nodes). In some aspects, an IAB donor can be a wireless node associated with a wired connection to a core network. For example, the wireless node 502-12 can include a CU that includes an NG interface connecting the CU to a core unit 510 (Next Generation Core (NGC) unit), and the core unit 510 can be a wireless node of the core network.

[0066] In some aspects, the wireless node 502-12 can communicate with the wireless nodes 502-10 and 502-11 via another interface. For example, the CU of the wireless node 502-12 can include an F1 interface to the respective DUs of the wireless nodes 502-10 and 502-11. Additionally or alternatively, the DU of the wireless node 502-12 (which can be a primary link endpoint) can include an NR Uu interface to the MT of the wireless node 502-11 (which can be a secondary link endpoint of the NR Uu interface) and a Radio Link Control Adaptation channel (RLC / Adapt) interface to the MT of the wireless node 502-11. Additionally or alternatively, the DU of the wireless node 502-12 can include one or more other interfaces (such as an NR Uu interface to the UE 120 (wireless node 504), etc.).

[0067] In some aspects, the wireless node 502-11 can communicate using one or more other interfaces. For example, the DU of the wireless node 502-11 can include an NR Uu interface to the MT of the wireless node 502-10, an RLC / Adapt interface to the MT of the wireless node 502-11, an NR Uu interface to the UE 120, and so on.

[0068] In full-duplex operation, a wireless communication device or wireless node (e.g., UE, BS, IAB node, etc.) can transmit and receive concurrently using the same frequency or frequency band. For example, a wireless node can transmit a first beam to a parent wireless node at a specific frequency and concurrently receive a second beam from a child wireless node at the same specific frequency. Similarly, the wireless node can receive a first beam from the parent wireless node and concurrently transmit a second beam to the child wireless node. Full-duplex operation can reduce overhead, increase capacity, reduce latency, and other examples related to beam sweeping. The wireless node can use full-duplex operation, for example, for Synchronization Signal Block (SSB) transmission, RMSI transmission, System Information Block (SIB) transmission, Random Access Channel (RACH) transmission, Channel State Information Reference Signal (CSI-RS) transmission, Sounding Reference Signal (SRS) transmission, etc.

[0069] As an example, a wireless node may receive and measure a first set of SSBs (such as cell definition SSBs (CD-SSBs), radio resource management SSBs (RRM-SSBs), etc.) from a parent wireless node, and use beam sweeping to concurrently transmit a second set of SSBs to child wireless nodes. Additionally or alternatively, the wireless node may transmit CSI-RS or RMSI transmissions to child wireless nodes concurrently with measuring or searching for the first set of SSBs from the parent wireless node. Similarly, a wireless node may transmit a RACH transmission to a parent wireless node and concurrently scan for one or more RACH transmissions from one or more child wireless nodes, UEs, or other wireless nodes. As another example, a wireless node may transmit a first SRS (such as a periodic SRS) to a parent wireless node and concurrently receive a second SRS (such as another periodic SRS) from a child wireless node. Additionally or alternatively, the wireless node may transmit a RACH transmission to a parent wireless node and concurrently receive a second SRS from a child wireless node. Additionally or alternatively, in full-duplex operation, the wireless node may transmit or receive (such as transmit to a parent wireless node and receive from a child wireless node, and vice versa) a set of other types of signals in two different directions.

[0070] The full-duplex capability may change over time. For example, a wireless node may support full-duplex communication for a particular beam pair at a particular frequency at a first time, but may not support full-duplex communication for that particular beam pair at that particular frequency at a second time. This may be related to the device capabilities of the wireless communication device, changing channel conditions, changing link budgets, changing transmit or receive power configurations, changing geographical situations (such as when the wireless communication device is moving or communicating with another moving wireless communication device), etc. Additionally, the wireless node may support full-duplex communication for some beam pairs but not for other beam pairs. For example, the wireless node may support full-duplex communication using a first beam pair including transmit beam q and receive beam r, but may not support full-duplex communication for a second beam pair including transmit beam s and receive beam t. This may be at least partially based on reflectors being positioned such that transmit beam s is reflected back to the antenna that will receive receive beam t. Additionally or alternatively, this may be at least partially based on a first antenna associated with transmit beam s and a second antenna associated with receive beam t being located on the same antenna panel, and the wireless node not having the full-duplex capability to concurrently transmit and receive within the same antenna panel (but having full-duplex capability for paired beams and corresponding paired antennas on different antenna panels).

[0071] Some aspects described herein implement beam sweep configurations for wireless nodes with full-duplex capabilities. For example, a wireless node may determine whether full-duplex communication is supported for a particular beam pair and may select a beam sweep configuration for full-duplex communication based at least in part on whether full-duplex communication is supported. In such examples, the beam sweep configuration may relate to beam width, beam shape, beam direction, beam order, a set of resources selected for transmission or reception, periodicity for beam sweeping, transmit or receive power, etc. At a later time, the wireless node may update the beam sweep configuration based at least in part on whether full-duplex communication is still supported for the particular beam pair or whether full-duplex communication is supported for one or more other beam pairs. In this way, the wireless node may implement full-duplex operation for beam sweep communication while adapting to changing conditions associated with full-duplex operation.

[0072] Figures 6A - 6C is a diagram illustrating an example beam sweep configuration for a wireless node with full-duplex capabilities according to various aspects of the present disclosure. As Figures 6A - 6C shown, a parent wireless node 602 (which includes a DU) may be in communication with a child wireless node 604 (which includes an MT and a DU). Although some aspects are described in terms of a parent wireless node and a child wireless node, other arrangements of wireless nodes are possible, as described above.

[0073] As Figure 6A further shown, at a first time, the parent wireless node 602 may perform beam sweeping to transmit a set of SSBs on a set of L transmit (Tx) beams 0 to L-1. Similarly, the child wireless node 604 may be configured to perform beam sweeping to transmit another set of SSBs on another set of L Tx beams 0 to L-1. Although some aspects are described in terms of a set of SSBs, other signaling may also be possible for beam sweeping (such as RMSI signaling, SIB type 1 (SIB1) signaling, RACH signaling, CSI-RS signaling, or SRS signaling, etc.).

[0074] In some aspects, the child wireless node 604 may measure or track SSB transmissions performed by the parent wireless node 602. For example, the child wireless node 604 may use a receive (Rx) beam j to measure the Tx beam 2 that conveys SSB 2. In such examples, the child wireless node 604 may determine that the child wireless node 604 is capable of full-duplex communication on the beam pair consisting of Rx beam j and Tx beam 2 and may enable full-duplex communication on that beam pair. For example, the child wireless node 604 may receive SSB 2 from the parent wireless node 602 and may transmit SSB 2 to a child wireless node of the child wireless node 604 on Tx beam 2.

[0075] As Figure 6BAs further shown in [0], at a second time, the sub wireless node 604 may determine that the full-duplex capability for a beam pair including Rx beam j and Tx beam 2 has changed. For example, the sub wireless node 604 may detect a threshold interference level associated with Rx beam j, or may receive an indication of the threshold interference level associated with Tx beam 2. Additionally or alternatively, the sub wireless node 604 may determine to re-evaluate whether full-duplex operation is permissible or suitable for, for example, Rx beam j and Tx beam 2, at least in part based on a timer expiration. For example, the sub wireless node 604 may periodically select a new beam sweep configuration to avoid poor performance associated with changing channel conditions. Additionally or alternatively, the sub wireless node 604 may detect a change in the channel conditions (such as the presence of another wireless node communicating on a frequency or frequency band, a change in the transmit power of the parent wireless node 602, etc.).

[0076] In some aspects, the sub wireless node 604 may select a different beam sweep configuration. For example, the sub wireless node 604 may determine to switch Tx beam 2 and Tx beam L-1 such that the sub wireless node 604 uses Tx beam L-1 to transmit SSB 2 and uses Tx beam 2 to transmit SSB L-1. In such examples, the sub wireless node 604 may determine that full-duplex operation is permissible or suitable for a beam pair including Rx beam j and Tx beam L-1. In some aspects, the beam sweep configuration may include a set of parameters such as beam width, beam direction, beam order, etc. For example, the sub wireless node 604 may determine to change the beam shape to reduce interference (such as by suppressing sidelobes in the direction causing interference). Additionally or alternatively, the sub wireless node 604 may set a set of resources to be used for beam sweeping for the beam sweep configuration. For example, the sub wireless node 604 may select a subset of SSB position candidates from a set of available SSB position candidates in which the SSBs within the SSB burst set will be transmitted. Additionally or alternatively, the sub wireless node 604 may set the periodicity for beam sweeping, the transmit power or receive power for monitoring Rx beam j and transmitting Tx beam L-1, respectively. In this way, the sub wireless node 604 achieves full-duplex operation with a reduced likelihood of interference compared to a static full-duplex operation configuration. In some aspects, the sub wireless node 604 may select a beam sweep configuration from a set of beam sweep configurations. For example, the sub wireless node 604 may store a set of beam sweep configurations that includes a set containing possible beam pairings, beam shapes, transmit powers, receive powers, etc. Additionally or alternatively, the sub wireless node 604 may receive information from the parent wireless node 602 identifying a set of beam sweep configurations that can be used for full-duplex operation.

[0077] In some aspects, the sub wireless node 604 may determine its own beam sweeping configuration. For example, the sub wireless node 604 may determine its full duplex capability and set the beam sweeping configuration accordingly. Additionally or alternatively, the sub wireless node 604 may receive information identifying the beam sweeping configuration from another wireless node. For example, the parent wireless node 602 or the central unit may determine the full duplex capability of the sub wireless node 604 and may transmit signaling identifying the corresponding beam sweeping configuration to the sub wireless node 604. In such examples, the parent wireless node 602 may determine the beam sweeping configuration at least in part based on a request received from the sub wireless node 604. For example, the sub wireless node 604 may detect a threshold interference level while operating in full duplex using a first beam sweeping configuration and may transmit a request to the parent wireless node 602 such that the parent wireless node 602 selects a second beam sweeping configuration to mitigate the threshold interference level. In such examples, the parent wireless node 602 or the sub wireless node 604 may use remaining minimum system information (RMSI) broadcast signaling, downlink control information (DCI) signaling, media access control (MAC) control element (CE) signaling, radio resource control (RRC) signaling, F1-AP interface signaling, etc. on the Uu interface to convey information identifying the beam sweeping configuration. The request may identify, for example, a synchronization signal block (SSB) where a failure of the first beam sweeping configuration is detected. The failure may include, for example, detecting a threshold interference level on the SSB.

[0078] In some aspects, the sub wireless node 604 may report one or more measurements to the parent wireless node 602 or use one or more measurements when selecting a beam sweeping configuration. Additionally or alternatively, the sub wireless node 604 or the parent wireless node 602 may use measurements performed by one or more other devices. For example, the sub wireless node 604 may use measurements performed by the parent wireless node 602 or by a sub wireless node of the sub wireless node 604, etc. to select a beam sweeping configuration for full duplex operation. The measurements may include, for example, reference signal received quality (RSRQ) measurements, received signal strength indicator (RSSI) measurements, signal to noise ratio (SNR) measurements, signal to interference and noise ratio (SINR) measurements, or self-interference measurements, etc. In some aspects, the sub wireless node 604 may modify the receiving component, the transmitting component, or both the receiving and transmitting components of the beam sweeping configuration, etc. For example, the sub wireless node 604 may change the beam sweeping configuration for a link to a sub wireless node of the sub wireless node 604 but may avoid changing the configuration of the backhaul link to the parent wireless node 602.

[0079] As Figure 6CAs further shown, at a third time, the child wireless node 604 may determine that the full-duplex capability for a beam pair including Rx beam j and Tx beam 2 has changed and full-duplex operation is not supported. In such examples, the child wireless node 604 may request that the parent wireless node 602 select a different beam sweep configuration. For example, the child wireless node 604 may transmit a MAC-CE including information requesting that the parent wireless node 602 select a different beam sweep configuration. In some aspects, the child wireless node 604 may include information identifying the beam sweep configuration in the MAC-CE. For example, the child wireless node 604 may include information requesting that the parent wireless node 602 use a specific beam to transmit a specific SSB. Additionally or alternatively, the child wireless node 604 may transmit a request regarding the selection of a beam sweep configuration by the parent wireless node 602. In such examples, the parent wireless node 602 may select the beam sweep configuration on its own. As shown, at least in part based on the selected beam sweep configuration, the parent wireless node 602 may switch Tx beam 2 and Tx beam L-1. Further, the child wireless node 604 may receive SSB 2 using Rx beam j and may concurrently transmit SSB L-1 using Tx beam L-1 in full-duplex.

[0080] Figure 7 is a flow chart illustrating an example process, e.g., performed by a wireless communication device, in accordance with various aspects of the present disclosure. The example process is an example in which a wireless communication device (e.g., BS110, UE 120, wireless nodes 502 and 504, parent wireless node 602, child wireless node 604, etc.) performs operations related to beam sweep configuration for a wireless node having full-duplex capability.

[0081] As Figure 7 shown, in some aspects, the process may include: determining the full-duplex capability of the wireless node for a specific beam pair (block 710). For example, the UE (using controller / processor 240, controller / processing 280, etc.) may determine the full-duplex capability of the wireless node for a specific beam pair as described above.

[0082] As Figure 7 shown, in some aspects, the process may include: selecting a beam sweep configuration for full-duplex communication at least in part based on the full-duplex capability of the wireless node for the specific beam pair (block 720).

[0083] As Figure 7As shown, in some aspects, the process may include: causing communication to occur using the specific beam pair according to the beam sweep configuration, at least in part based on selecting the beam sweep configuration (block 730). For example, the UE (using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, etc.) may cause communication to occur using the specific beam pair according to the beam sweep configuration, at least in part based on selecting the beam sweep configuration, as described above.

[0084] The process may include additional aspects, such as any individual aspect or any combination of aspects described below or in combination with one or more other processes described elsewhere herein.

[0107] Figure 8 is a flowchart illustrating an example process, such as that performed by a wireless communication device, in accordance with various aspects of the present disclosure. The example process is an example where a parent wireless node (e.g., BS110, UE 120, wireless nodes 502 and 504, parent wireless node 602, etc.) performs operations related to a beam sweep configuration for a wireless node with full-duplex capability.

[0108] As Figure 8 shown, in some aspects, the process may include: determining the full-duplex capability of a child wireless node for a particular beam pair (block 810). For example, the parent wireless node (using controller / processor 240, controller / processing 280, etc.) may determine the full-duplex capability of the child wireless node for a particular beam pair, as described above.

[0109] As Figure 8 further shown, in some aspects, the process may include: selecting a beam sweep configuration for at least one of the parent wireless node or the child wireless nodes at least partially based on the full-duplex capability of the child wireless node for the particular beam pair (block 820). For example, the parent wireless node (using controller / processor 240, controller / processing 280, etc.) may select a beam sweep configuration for at least one of the parent wireless node or the child wireless nodes at least partially based on the full-duplex capability of the child wireless node for the particular beam pair, as described above.

[0110] As Figure 8 further shown, in some aspects, the process may include: causing communication to occur using the particular beam pair according to the beam sweep configuration at least partially based on selecting the beam sweep configuration (block 830). For example, the parent wireless node (using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, etc.) may cause communication to occur using the particular beam pair according to the beam sweep configuration at least partially based on selecting the beam sweep configuration, as described above.
