[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 954,205, filed on December 27, 2019, entitled “SLOT FORMAT CONFIGURATION TO SUPPORT FULL-DUPLEX OPERATION,” and U.S. Non-Provisional Patent Application No. 17 / 129,328, filed on December 21, 2020, entitled “SLOT FORMAT CONFIGURATION TO SUPPORT FULL-DUPLEX OPERATION,” which are hereby expressly incorporated herein by reference.

[0003] Public domain

[0004] Aspects of the present disclosure relate generally to wireless communications and, more particularly, to techniques and apparatus for providing time slot format configuration to support full-duplex operation.

[0005] background

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth or transmit power). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment (UE) to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using 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 improvements in LTE and NR technologies. Preferably, these improvements are applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0008] In a wireless network, a control node may configure a wireless node to have a time slot configuration for downlink communication or uplink communication. However, the control node may not be able to signal to the wireless node a time slot configuration including one or more time slots or symbols that can be used for full-duplex communication, which generally refers to simultaneous transmission and reception at a specific frequency. For example, existing time slot formats generally have a structure in which time slots or symbols can be marked as downlink only, uplink only, or flexible (downlink or uplink, not both). Accordingly, even if the control node and the wireless node have the ability to perform full-duplex communication, the control node may not be configured to configure a wireless communication link between the wireless node and another wireless node (e.g., a child node of the wireless node) so that a time slot configuration that can utilize full-duplex communication capabilities can be utilized. As a result, the wireless node may experience reduced throughput on the wireless communication link or increased latency on the wireless communication link, etc.

[0033] Detailed Description

[0034] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and is not interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, those skilled in the art can appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. Any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0035] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0036] Various aspects generally relate to providing a time slot format configuration to a wireless node (e.g., a UE or an integrated access and backhaul (IAB) node, etc.) to support full-duplex operation. Some aspects particularly relate to a control node (e.g., a base station, an IAB donor, or a parent IAB node) transmitting one or more signaling messages to the wireless node, the one or more signaling messages explicitly indicating one or more time slots or symbols configured to support full-duplex operation. Additionally or alternatively, the one or more signaling messages may include one or more signaling messages in which one or more time slots or symbols are marked as downlink-only or uplink-only, and subsequent signaling messages may re-mark these downlink-only time slots or symbols as uplink or flexible time slots or symbols, or re-mark these uplink-only time slots or symbols as downlink or flexible time slots or symbols to implicitly indicate the time slots or symbols configured to support full-duplex operation. Accordingly, in some aspects, a wireless node may use the slot format configuration to communicate with another wireless node (e.g., a child node of the wireless node) in a slot or symbol configured to support full-duplex operation. In addition, in some aspects, a wireless node may apply one or more rules to selectively perform full-duplex operation in a slot or symbol marked as full-duplex or flexible, perform half-duplex operation in a direction that conflicts with the symbol type (e.g., perform downlink communication in an uplink symbol or perform uplink communication in a downlink symbol), or perform full-duplex operation in one or more symbols or slots marked as uplink-only or downlink-only.

[0037] Certain aspects of the subject matter described in the present disclosure may be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques may be used to enable a wireless node to simultaneously perform uplink and downlink communications in a full-duplex, flexible, downlink-only, or uplink-only time slot or symbol. In some examples, the described techniques may be used to provide a wireless node with the flexibility to perform half-duplex operation in a direction opposite to the scheduled time slot or symbol type. In this way, a wireless node can transmit and receive a larger amount of communication relative to a time slot or symbol limited to only uplink or only downlink, which increases the throughput on the wireless communication link between the wireless node and the other wireless node. In addition, this ability to perform full-duplex communication reduces the amount of time that the communication must be delayed before it can be transmitted to or received by the wireless node, which reduces the latency on the wireless communication link. In addition, the described techniques may be used to increase flexibility in scheduling communications for wireless nodes (e.g., by providing a time slot format configuration that enables scheduling of full-duplex communications or half-duplex communications that are not constrained to downlink or uplink directions, etc.).

[0038] Figure 1is a diagram illustrating an example of a wireless network according to various aspects of the present disclosure. The wireless network may be a 5G (NR) network or an LTE network, etc. or may include elements thereof. The wireless network may include one or more base stations 110 (shown as base station 110a, base station 110b, base station 110c, and base station 110d) and other network entities. A base station is an entity that communicates with a user equipment (UE) and may also be referred to as an NR base station, a B node, a gNB, a 5G B node (NB), an access point, or a transmit receive point (TRP), etc. Each base station may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a base station or a base station subsystem that serves the coverage area, depending on the context in which the term is used.

[0039] A base station may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) and may allow unrestricted access by a UE with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by a UE associated with the femto cell (e.g., a UE in a closed subscriber group (CSG)). A base station for a macro cell may be referred to as a macro base station. A base station for a pico cell may be referred to as a pico base station. A base station for a femto cell may be referred to as a femto base station or a home base station. A base station may support one or more (e.g., three) cells.

[0040] The wireless network may be a heterogeneous network including different types of base stations, such as macro base stations, pico base stations, femto base stations, or relay base stations. These different types of base stations may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network. For example, a macro base station may have a high transmit power level (e.g., 5 to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 to 2 watts). Figure 1 In the example shown in , base station 110a can be a macro base station for macro cell 102a, base station 110b can be a pico base station for pico cell 102b, and base station 10c can be a femto base station for femto cell 102c. A network controller 130 can be coupled to a set of base stations 102a, 102b, 110a, and 110b, and can provide coordination and control of these base stations. The network controller 130 can communicate with the base stations via a backhaul. The base stations can also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0041] In some aspects, the cell may not be stationary; instead, the geographic area of ​​the cell may move depending on the location of the mobile base station. In some aspects, the base stations may be interconnected to each other and / or to one or more other base stations or network nodes (not shown) in the wireless network through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0042] The wireless network may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a base station or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a base station). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay station 110d may communicate with a macro base station 110a and a UE 120d to facilitate communication between the base station 110a and the UE 120d. A relay station may also be referred to as a relay base station, a relay, or the like.

[0043] UE 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, or station, etc. UE may 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, an ultrabook, 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.

[0044] Some UEs may be considered as 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, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component or a memory component.

[0045] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies or frequency channels. Frequencies may also be referred to as carriers, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0046] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may use one or more sidelink channels to communicate directly with each other (e.g., without using base station 110 as an intermediary). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), mesh networks, or a combination thereof. In such examples, UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by base station 110.

[0047] The devices of a wireless network can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, or channels based on frequency or wavelength. For example, the devices of a wireless network can communicate using an operating frequency band having a first frequency range (FR1) that can span from 410 MHz to 7.125 GHz. As another example, the devices of a wireless network can communicate using an operating frequency band having a second frequency range (FR2) that can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz band." Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that the term "sub-6 GHz" can broadly represent a frequency less than 6 GHz, a frequency within FR1, a mid-band frequency (e.g., greater than 7.125 GHz), or a combination thereof. Similarly, unless otherwise specifically stated, it should be understood that the term "millimeter wave" can broadly refer to frequencies within the EHF band, frequencies within FR2, mid-band frequencies (e.g., less than 24.25 GHz), or a combination thereof. The frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0048] Figure 2 is a diagram illustrating an example base station in communication with a UE in a wireless network according to various aspects of the present disclosure. The base station may correspond to Figure 1 Similarly, the UE may correspond to the base station 110. Figure 1 UE120.

[0049] 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 in general T ≥ 1 and R ≥ 1. At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode) the data for each UE based at least in part on the MCS selected for the 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) and control information (e.g., CQI requests, grants, or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals and synchronization signals. A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a to 232t. Each MOD 232 may process a 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 to 232t may be transmitted via T antennas 234a to 234t, respectively.

[0050] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 or other base stations, and may provide received signals to R demodulators (DEMODs) 254a to 254r, respectively. Each DEMOD 254 may condition (e.g., filter, amplify, downconvert, 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. A MIMO detector 256 may obtain symbols received from all R DEMODs 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination of one or more controllers and one or more processors. The channel processor may determine one or more of a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0051] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0052] Antennas, such as antennas 234a to 234t or antennas 252a to 252r, may include or be included within one or more antenna panels, antenna groups, sets of antenna elements, or antenna arrays. An antenna panel, antenna group, set of antenna elements, or antenna array may include one or more antenna elements. An antenna panel, antenna group, set of antenna elements, or antenna array may include a coplanar set of antenna elements or a non-coplanar set of antenna elements. An antenna panel, antenna group, set of antenna elements, or antenna array may include antenna elements within a single housing or antenna elements within multiple housings. An antenna panel, antenna group, set of antenna elements, or antenna array may include antenna elements coupled to one or more transmission or reception components, such as Figure 2 One or more antenna elements of one or more components).

[0053] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, or CQI) from the controller / processor 280. 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, if applicable, further processed by the MODs 254a to 254r (e.g., for discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM), or orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM)), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator 254, demodulator 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 methods described herein.

[0054] At the base station 110, 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 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator 232, demodulator 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 methods described herein.

[0055] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of may perform one or more techniques associated with the time slot format configuration to support full-duplex operation, as described in more detail elsewhere herein. Additionally or alternatively, a node (e.g., an IAB node, an IAB donor, a control node, an IAB child node, or an IAB parent node) in an integrated access and backhaul (IAB) network or another suitable wireless network may perform one or more techniques associated with the time slot format configuration to support full-duplex operation. As described in more detail elsewhere herein, such a node may be an IAB child node or another suitable node including a mobile termination (MT) component and a distributed unit (DU) component. Additionally or alternatively, the node may be an IAB donor node, an IAB parent node, or another suitable node including a central unit (CU) component and a DU component. In some aspects, the MT component may perform one or more functions of the UE 120 as described herein, or may include one or more components of the UE 120 as described herein. In some aspects, the DU component may perform one or more functions of the base station 110 as described herein, such as scheduling, or may include one or more components of the base station 110 as described herein. In some aspects, the CU component may perform one or more functions of the base station 110 as described herein, such as configuration for other nodes, or may include one or more components of the base station 110 as described herein.

[0056] In some respects, Figure 2 The controller / processor 240 of the base station 110 or node (e.g., IAB donor node or IAB parent node), the controller / processor 280 of the UE 120 or node (e.g., IAB child node), or any other component may perform or direct, for example, Fig. 9 The process of 900 Fig.10 1000, or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 or 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, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, or interpretation) by one or more processors of base station 110 or UE 120, may cause the one or more processors, UE 120, or base station 110 to perform or direct, for example, Fig. 9 The process of 900 Fig.10 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, or interpreting instructions, etc.

[0057] In some aspects, a wireless node (such as UE 120, an IAB node, or an MT component of an IAB node) may include: a device for receiving information identifying a time slot configuration mode for a wireless communication link between the wireless node and another wireless node (such as a child node of the wireless node) from a control node (such as base station 110, an IAB donor node, an IAB parent node, a DU component, or a CU component), wherein the information identifying the time slot configuration mode may indicate one or more code elements configured to support full-duplex communication; or a device for communicating with the other wireless node in the one or more code elements configured to support full-duplex communication according to the time slot configuration mode; etc. In some aspects, such a device may include a device in combination with Figure 2 One or more components of UE 120 or base station 110 are depicted (which may be included in a wireless node).

[0058] In some aspects, the control node may include means for determining a time slot configuration mode for a wireless communication link between a wireless node and another wireless node, or means for transmitting information identifying the time slot configuration mode for the wireless link to the wireless node, wherein the information identifying the time slot configuration mode indicates one or more code elements configured to support full-duplex communication. In some aspects, such means may include in conjunction with Figure 2 One or more components of base station 110 are described.

[0059] Figure 3 is a diagram illustrating an example of a frame structure for use in a wireless network in accordance with various aspects of the present disclosure. For example, the frame structure may be used for frequency division duplex (FDD) in a telecommunication system (e.g., NR). The transmission timeline for each of the downlink and uplink directions may be divided into units of radio frames (sometimes simply referred to as "frames"). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z ≥ 1) subframes (e.g., with indices 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., in Figure 3 Each subframe 2 is shown m time slots, where m is a parameter design for transmission, such as 0, 1, 2, 3, 4, etc., or a combination thereof). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3 ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two time slots (e.g., when m=1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices 0 to 2L–1. In some aspects, the scheduling unit for FDD may be frame-based, subframe-based, slot-based, symbol-based, etc., or a combination thereof.

[0060] Although some techniques are described herein in connection with frames, subframes, or time slots, etc., or a combination thereof, these techniques may be equally applicable to other types of wireless communication structures that may be referred to using terms other than "frames," "subframes," or "time slots" in 5G NR. In some aspects, a "wireless communication structure" may refer to a periodic, time-bounded communication unit defined by a wireless communication standard or protocol. Additionally or alternatively, a term similar to Figure 3 The wireless communication structure configurations are different from those shown in FIG.

[0061] In some telecommunications (e.g., NR), a base station may transmit synchronization signals. For example, a base station may transmit a primary synchronization signal (PSS) or a secondary synchronization signal (SSS) on the downlink for each cell supported by the base station. The PSS and SSS may be used by the UE for cell search and acquisition. For example, the PSS may be used by the UE to determine symbol timing, while the SSS may be used by the UE to determine the physical cell identifier associated with the base station and the frame timing. The base station may also transmit a physical broadcast channel (PBCH). The PBCH may carry some system information, such as system information that supports initial access of the UE.

[0062] In some aspects, the base station may transmit the PSS, SSS, or PBCH according to a synchronization communication level (e.g., a synchronization signal (SS) level) including multiple synchronization communications (e.g., SS blocks (SSBs)).

[0063] Figure 4 is a diagram illustrating an example of a slot format according to various aspects of the present disclosure. Available time-frequency resources may be divided into resource blocks. Each resource block may cover a set of subcarriers (e.g., 12 subcarriers) in a slot and may include a number of resource elements. Each resource element may cover one subcarrier in a symbol period (e.g., in time) and may be used to send one modulation symbol, which may be a real value or a complex value.

[0064] For FDD in some telecommunication systems (e.g., NR), an interleaving structure may be used for each of the downlink and uplink. For example, Q interleavings with indices 0 to Q–1 may be defined, where Q may be equal to 4, 6, 8, 10, or some other value. Each interleaving may include time slots spaced apart by Q frames. Specifically, interleaving q may include time slots q, q+Q, q+2Q, etc., where q∈{0,…,Q–1}.

[0065] A UE may be located within the coverage of multiple base stations. One of these base stations may be selected to serve the UE. The serving base station may be selected based at least in part on various criteria such as received signal strength, received signal quality, or path loss, etc. Received signal quality may be quantified by channel interference plus noise ratio (SINR), reference signal received quality (RSRQ), or some other metric. A UE may operate in a dominant interference scenario in which the UE may observe severe interference from one or more interfering base stations.

[0066] Although aspects of the examples described herein may be associated with NR or 5G technology, aspects of the present disclosure may be applicable to other wireless communication systems. New Radio (NR) may refer to a radio configured to operate according to a new air interface (e.g., an air interface different from that based on Orthogonal Frequency Division Multiple Access (OFDMA)) or a fixed transport layer (e.g., different from Internet Protocol (IP)). In various aspects, NR may utilize OFDM with a cyclic prefix (CP) (referred to herein as cyclic prefix OFDM or CP-OFDM) or SC-FDM on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using time division duplex (TDD). In various aspects, NR may, for example, utilize OFDM with a CP (referred to herein as CP-OFDM) or DFT-s-OFDM on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include enhanced mobile broadband (eMBB) services targeting wide bandwidth (e.g., 80 megahertz (MHz) and above), millimeter wave (mmW) targeting high carrier frequencies (e.g., 60 gigahertz (GHz)), massive MTC (mMTC) targeting non-backward compatible MTC technology, or mission critical services targeting ultra-reliable low latency communication (URLLC) services.

[0067] In some aspects, a single component carrier bandwidth of 100 MHZ may be supported. NR resource blocks may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) over a duration of 0.1 milliseconds (ms). Each radio frame may include 40 slots and may have a length of 10 ms. Thus, each slot may have a length of 0.25 ms. Each slot may indicate a link direction (e.g., downlink (DL) or uplink (UL)) for data transmission, and the link direction for each slot may be dynamically switched. Each slot may include DL / UL data and DL / UL control data.

[0068] Beamforming may be supported, and the beam direction may be dynamically configured. MIMO transmission with precoding may also be supported. MIMO configuration in DL may support up to 8 transmit antennas (multi-layer DL transmission with up to 8 streams) and up to 2 streams per UE. Aggregation of multiple cells may be supported using up to 8 serving cells. Alternatively, NR may support different air interfaces other than OFDM-based interfaces. NR networks may include entities such as a central unit or a distributed unit.

[0069] Figure 5 is a diagram illustrating an example of a radio access network according to various aspects of the present disclosure. Figure 5 As shown in , a radio access network (RAN) may include a RAN 505, such as a 3G RAN, a 4G RAN, an LTE RAN, or a 5G NR RAN. The RAN 505 may include multiple base stations 510 or access nodes (ANs) 510, each of which communicates with a core network via a wired backhaul link 515 (such as a fiber optic connection). The base station 510 or AN 510 may communicate with a UE 520 via a wireless access link 525. In some aspects, Figure 5 The base station 510 or AN 510 shown in FIG. 5 may be a reference Figure 1 or Figure 2 An example of a base station 110 is described. In some aspects, Figure 5 The UE 520 shown in FIG. 5 may be a reference Figure 1 or Figure 2 An example of a UE 120 is described.

[0070] like Figure 5 As further shown in , the RAN 505 may include a wireless backhaul network 530 (sometimes also referred to as an integrated access and backhaul (IAB) network). In an IAB network, at least one base station is an anchor base station 535, which communicates with the core network via a wired backhaul link 540 (such as a fiber connection). The anchor base station 535 may also be referred to as an IAB donor (or IAB-donor). The IAB network 530 also includes one or more non-anchor base stations 545 (sometimes referred to as relay base stations or IAB nodes (or IAB-nodes)). The non-anchor base station 545 may communicate with the anchor base station 535 directly or indirectly (for example, via one or more other non-anchor base stations 545) via one or more backhaul links 550 to form a backhaul path to the core network for carrying backhaul traffic. The anchor base station(s) 535 or the non-anchor base station(s) 545 may communicate with one or more UEs 555 via a wireless access link 560 that carries access traffic. In some aspects, Figure 5 The anchor base station 535 or the non-anchor base station 545 shown in FIG. Figure 1 or Figure 2An example of a base station 110 is described. In some aspects, Figure 5 The UE 555 shown in FIG. 5 may be a reference Figure 1 or Figure 2 An example of a UE 120 is described.

[0071] like Figure 5 As further shown in , the RAN may include an IAB network 565, which may utilize millimeter wave (mmW) technology for directional communication (e.g., via beamforming) between base stations or UEs (e.g., between two base stations, between two UEs, or between a base station and a UE). For example, a mmW wireless backhaul link 570 between base stations may enable a base station to use beamforming to direct a signal carrying information to a target base station. Similarly, a wireless access link 575 between a UE and a base station may enable the UE or the base station to transmit a beamformed mmW signal to a target wireless node (such as a base station or UE). In this way, inter-link interference may be reduced.

[0072] Figure 5 The configurations of the base stations and UEs shown in are examples, and other examples are contemplated. For example, Figure 5 The one or more base stations illustrated in the figure may be replaced by one or more UEs communicating via a side link between UEs through a UE-to-UE access network (e.g., a peer-to-peer network or a device-to-device network). In such examples, an anchor node may refer to a UE that directly communicates with a base station (such as an anchor base station or a non-anchor base station).

[0073] Figure 6 is a diagram illustrating an example of an IAB network architecture according to various aspects of the present disclosure. Figure 6 As shown in , the IAB network may include an IAB donor 605 (shown as IAB-donor) connected to the core network via a wired connection (shown as wired backhaul). For example, the Ng interface of the IAB donor 605 may terminate at the core network. Additionally or alternatively, the IAB donor 605 may be connected to one or more devices (e.g., access and mobility management function (AMF) entities) of the core network that provide core access and mobility management functions. In some aspects, the IAB donor 605 may include a base station 110, such as described above in conjunction with Figure 5Anchor base station described. As shown, the IAB donor 605 may include a central unit (CU), which may perform access node controller (ANC) functions or AMF functions, etc. In some aspects, the CU may configure a distributed unit (DU) of the IAB donor 605, or may configure one or more IAB nodes 610 (e.g., an MT or DU of the IAB node 610) connected to the core network via the IAB donor 605. Accordingly, the CU of the IAB donor 605 may control or configure the entire IAB network connected to the core network via the IAB donor 605, such as by using a control message or a configuration message (such as a radio resource control (RRC) configuration message or an F1 application protocol (F1AP) message, etc.).

[0074] like Figure 6 As further shown in FIG. 1 , the IAB network may include an IAB donor 610 (shown as IAB-node 1, IAB-node 2, and IAB-node 3) connected to the core network via an IAB donor 605. As shown, the IAB node 610 may include a mobile termination (MT) function (sometimes referred to as a UE function (UEF)) and may include a DU function (sometimes referred to as an access node function (ANF)). The MT function of an IAB node 610 (e.g., a child node) may be controlled or scheduled by another IAB node 610 (e.g., a parent node of the child node) or by the IAB donor 605. In some aspects, the DU function of an IAB node 610 (e.g., a parent node) may control or schedule other IAB nodes 410 (e.g., a child node of the parent node) or UE 120. Accordingly, in some aspects, the DU may be referred to as a scheduling node or scheduling component, and the MT may be referred to as a scheduled node or scheduled component. In some aspects, the IAB donor 605 may include a DU function but not an MT function. That is, the IAB donor 605 may configure, control or schedule the communication of the IAB node 610 or the UE 120. The UE 120 may include only the MT function but not the DU function. That is, the communication of the UE 120 may be controlled or scheduled by the IAB donor 605 or the IAB node 610 (e.g., the parent node of the UE 120).

[0075] In some aspects, when a first node controls or schedules communications for a second node (e.g., when the first node provides a DU function for an MT function of the second node), the first node may be referred to as a parent node of the second node, and the second node may be referred to as a child node of the first node. The child node of the second node may be referred to as a grandchild node of the first node. Thus, the DU function of the parent node may control or schedule communications for the child node of the parent node. The parent node may be an IAB donor 605 or an IAB node 610, and the child node may be an IAB node 610 or a UE 120. Communications of the MT function of the child node may be controlled or scheduled by the parent node of the child node.

[0076] like Figure 6 As further shown in FIG. 1 , the link between a UE 120 having only MT functionality but not DU functionality and an IAB donor 605 or between a UE 120 and an IAB node 610 may be referred to as an access link 615. The access link 615 may be a wireless access link that provides radio access to the core network to the UE 120 via the IAB donor 605 and optionally via one or more IAB nodes 610. Thus, Figure 6 The network illustrated in may be referred to as a multi-hop network or a wireless multi-hop network.

[0077] like Figure 6 As further shown in , the link between the IAB donor 605 and the IAB node 610 or between two IAB nodes 610 may be referred to as a backhaul link 620, which may be a wireless backhaul link that provides radio access to the core network to the IAB node 610 via the IAB donor 605 and optionally via one or more other IAB nodes 610. In some aspects, the backhaul link 620 may be a primary backhaul link or a secondary backhaul link (e.g., a backup backhaul link). In some aspects, the secondary backhaul link may be used when the primary backhaul link fails, becomes congested, or becomes overloaded. For example, the backup link 625 between the IAB-node 2 and the IAB-node 3 may be used for backhaul communication based at least in part on the failure of the primary backhaul link between the IAB-node 2 and the IAB-node 1. As used herein, a node or wireless node may refer to the IAB donor 605 or the IAB node 610.

[0078] In the IAB network, network resources (e.g., time resources, frequency resources, or space resources) used for wireless communication can be shared between the access link 615 and the backhaul link 620. In some cases, the CU of the IAB donor 610 can be configured for the resource mode of the IAB node 610 in the IAB network. For example, the time resource (e.g., time slot or codeword) can be configured as downlink only, uplink only, flexible, or unavailable (or "unavailable"). When the time resource is configured as downlink only for a wireless node, the time resource can be used for downlink-only communication of the wireless node, but not for uplink communication of the wireless node. Similarly, when the time resource is configured as uplink only for a wireless node, the time resource can be used for uplink-only communication of the wireless node, but not for downlink communication of the wireless node. When the time resource is configured as flexible for a wireless node, the time resource can be used for downlink communication or uplink communication of the wireless node. When the time resource is configured as unavailable for a wireless node, the time resource cannot be used for any communication of the wireless node.

[0079] A time resource configured as downlink-only, uplink-only, or flexible in an IAB network may be further configured as a hard resource or a soft resource. When a time resource is configured as a hard resource for a wireless node, the time resource is always available for communication by the wireless node. For example, a downlink-only hard time resource is always available for downlink-only communication of a wireless node, an uplink-only hard time resource is always available for uplink-only communication of a wireless node, and a flexible hard time resource is always available for uplink and downlink communication of a wireless node.

[0080] When a time resource is configured as a soft resource for a wireless node, the availability of the time resource is controlled by the parent node of the wireless node (such as the DU of the parent node). For example, the parent node may explicitly or implicitly indicate whether the soft time resource is available for communication of the wireless node. Accordingly, the soft time resource may be in one of the following two states: a schedulable state (e.g., when the soft time resource is available for scheduling or communication of the wireless node) and an unschedulable state (e.g., when the soft time resource is not available for scheduling and is not available for communication of the wireless node). For example, when the parent node of the wireless node indicates that only downlink soft time resources are available, the downlink-only soft time resources can only be used for downlink communication of the wireless node. Similarly, when the parent node of the wireless node indicates that only uplink soft time resources are available, the uplink-only soft time resources can only be used for uplink communication of the wireless node. When the parent node of the wireless node indicates that flexible soft time resources are available, the flexible soft time resources can only be used for uplink and downlink communication of the wireless node.

[0081] Figures 7A-7C is a diagram illustrating an example of full-duplex communication according to various aspects of the present disclosure. Figures 7A-7C As shown in , full-duplex communication can be performed between one or more upstream wireless nodes 710 (such as one or more base stations, TRPs, parent IAB nodes, or DUs of IAB nodes, etc.) and one or more downstream wireless nodes (such as one or more UEs, child IAB nodes, or MTs of IAB nodes, etc.) in a wireless network. For example, in Figures 7A-7C , the one or more upstream wireless nodes 710 are illustrated as base stations or TRPs, and the one or more downstream wireless nodes 720 are illustrated as one or more UEs. Figures 7A-7C The devices shown in are only examples, and full-duplex communication may be supported between other suitable devices in the wireless network (eg, between an MT node and a control node, between an IAB child node and an IAB parent node, or between a scheduled node and a scheduling node, etc.).

[0082] like Fig. 7AAs shown in , the downstream wireless node 720 may be in communication with two upstream wireless nodes 710-1, 710-2. Fig. 7A As shown in , the downstream wireless node 720 may transmit one or more uplink transmissions to the upstream wireless node 710-1 and may concurrently receive one or more downlink transmissions from the upstream wireless node 710-2. Fig. 7A In the example shown in , full-duplex communication is enabled for the downstream wireless node 720 (which may be operating as a full-duplex node), but full-duplex communication is not enabled for the upstream wireless nodes 710-1, 710-2 (which may be operating as half-duplex nodes). Figure 7B , two downstream wireless nodes 720-1 and 720-2 are in communication with an upstream wireless node 710. In such an example, the upstream wireless node 710 may transmit one or more downlink transmissions to the first downstream wireless node 720-1 and may concurrently receive one or more uplink transmissions from the second downstream wireless node 720-2. Figure 7B In the example shown in , full-duplex communication is enabled for the upstream wireless node 710 (which may be operating as a full-duplex node), but full-duplex communication is not enabled for the downstream wireless nodes 720-1 and 720-2 (which may be operating as half-duplex nodes). Figure 7C As shown in , the downstream wireless node 720 may be in communication with the upstream wireless node 710. In such examples, the upstream wireless node 710 may transmit and the downstream wireless node 720 may receive one or more downlink transmissions, while the downstream wireless node 720 transmits and the upstream wireless node 710 receives one or more uplink transmissions. Accordingly, in Figure 7C In the example shown in , full-duplex communication is enabled for both the downstream wireless node 720 and the upstream wireless node 710, each of which is operating as a full-duplex node.

[0083] The present disclosure generally relates to improving the way of flexible time division duplex (TDD) operation to support full-duplex communication (which generally refers to simultaneous uplink and downlink transmission). For example, in some cases, the nodes in the IAB network are subject to half-duplex constraints, which means that a particular node cannot transmit and receive information at the same time (e.g., cannot communicate concurrently or simultaneously via an access link and a backhaul link, or cannot communicate concurrently or simultaneously via an uplink and a downlink, etc.). Such constraints may result in high latency or reduced throughput, etc. Accordingly, in some cases, in order to reduce latency, increase throughput, or improve reliability, the nodes in the IAB network may support full-duplex communication capabilities, which refer to simultaneous transmission and reception operations (e.g., simultaneous uplink and downlink operations at a specific frequency). However, the control node may not be able to signal to a wireless node (e.g., a parent IAB node) a time slot configuration including one or more time slots or symbols that can be used for full-duplex communication with another node (e.g., a child node of the wireless node). For example, existing time slot formats generally have a structure in which time slots or symbols can be marked as downlink only, uplink only, or flexible (downlink or uplink, not both). Accordingly, even if wireless nodes support full-duplex communication, the control node may not be able to configure a time slot configuration for a wireless communication link between these wireless nodes that enables full-duplex communication capabilities to be utilized. As a result, there may be reduced throughput on the wireless communication link or increased latency on the wireless communication link, etc.

[0084] Various aspects generally relate to providing a time slot format configuration to a wireless node to support full-duplex operation between the wireless node and another wireless node. Some aspects relate in particular to a control node (e.g., a base station, an IAB donor, or a parent IAB node) providing a time slot format configuration to a wireless node, which the wireless node can use to perform full-duplex communication with another wireless node (such as a child node of the wireless node). For example, the control node may transmit one or more signaling messages to the wireless node, the signaling message explicitly indicating one or more time slots or symbols configured to support full-duplex operation. Additionally or alternatively, the one or more signaling messages may include one or more signaling messages in which one or more time slots or symbols are marked as downlink-only or uplink-only, and subsequent signaling messages may re-mark these downlink-only time slots or symbols as uplink or flexible time slots or symbols, or re-mark these uplink-only time slots or symbols as downlink or flexible time slots or symbols to implicitly indicate time slots or symbols configured to support full-duplex operation. Accordingly, in some aspects, a wireless node may use the slot format configuration to communicate with another wireless node (e.g., a child node of the wireless node) in a slot or symbol configured to support full-duplex operation. In addition, in some aspects, a wireless node may apply one or more rules to selectively perform full-duplex operation in a slot or symbol marked as full-duplex or flexible, perform half-duplex operation in a direction that conflicts with the symbol type (e.g., perform downlink communication in an uplink symbol or perform uplink communication in a downlink symbol), or perform full-duplex operation in one or more symbols or slots marked as uplink-only or downlink-only.

[0085] Certain aspects of the subject matter described in the present disclosure may be implemented to achieve one or more of the following potential advantages. In one example, the described techniques may be used to enable a wireless node to simultaneously perform uplink and downlink communications in a full-duplex, flexible, downlink-only, or uplink-only time slot or symbol. In some examples, the described techniques may be used to provide a wireless node with the flexibility to perform half-duplex operation in a direction opposite to the scheduled time slot or symbol type. In this way, a wireless node can transmit and receive a larger amount of communication relative to a time slot or symbol limited to only uplink or only downlink, which increases the throughput on the wireless communication link between the wireless node and the other wireless node. In addition, this ability to perform full-duplex communication reduces the amount of time that the communication must be delayed before it can be transmitted to or received by the wireless node, which reduces the latency on the wireless communication link. In addition, the described techniques may be used to increase flexibility in scheduling communications for wireless nodes (e.g., by providing a time slot format configuration that enables scheduling of full-duplex communications or half-duplex communications that are not constrained to downlink or uplink directions, etc.).

[0086] Figure 8 is a diagram illustrating an example associated with providing a time slot format configuration to support full-duplex operation according to various aspects of the present disclosure. Figure 8 In the example shown in , a control node 810 (e.g., a base station, a CU, or an IAB donor) may provide a time slot format configuration supporting full-duplex operation to a wireless node 820, which may use the time slot format configuration to communicate with another wireless node 830 (such as a child node of the wireless node 820) over a wireless link. For example, in some aspects, the wireless node 830 may be a UE, the wireless node 820 may be a base station or an IAB node, and the wireless link between the wireless node 820 and the wireless node 830 may be an access link (for example, each of which is described above with reference to Figure 1 -7 are described). Additionally or alternatively, in some aspects, the wireless node 830 may be a child IAB node, the wireless node 820 may be a parent IAB node or an IAB donor, and the wireless link between the wireless node 820 and the wireless node 830 may be a backhaul link or a backup link, etc., as described above. In addition, as described herein, the wireless nodes 820, 830 may support full-duplex communication with each other, which generally refers to the ability of the wireless node 830 to simultaneously transmit information on the uplink and receive information on the downlink, or the ability of the wireless node 820 to simultaneously transmit information on the downlink and receive information on the uplink, etc.

[0087] like Figure 8 As indicated in, in a first operation 840, the control node 810 may transmit and the wireless node 820 may receive cell-specific signaling or dedicated signaling indicating a time slot configuration mode. In some aspects, as described herein, the time slot configuration mode indicated in the cell-specific signaling or dedicated signaling may include one or more time slots or symbols supporting full-duplex communication.

[0088] For example, in some aspects, the cell-specific signaling may include radio resource control (RRC) signaling, which includes one or more parameters to define a semi-static time slot configuration mode in a cell associated with the control node 810 or the wireless node 820. For example, the one or more parameters may include a common time division duplex (TDD) configuration to be used in the cell, and the control node 810 or the wireless node 820 may broadcast the common TDD configuration via a system information block (SIB). In some aspects, the common TDD configuration may include a time slot configuration period and a reference subcarrier spacing (SCS) (which may define the number of time slots in the time slot configuration period). In addition, in some aspects, the common TDD configuration may indicate a time slot configuration mode associated with the cell. For example, the time slot configuration mode may include the number of full downlink time slots (dslots) containing only downlink codewords, the number of downlink codewords (dsym), the number of full uplink time slots (uslots) containing only uplink codewords, the number of uplink codewords (usym), or the number of flexible codewords, etc. For example, as Figure 8 As shown in , the time slot configuration period 850 can be configured according to a mode in which the time slot configuration period 850 includes the following items: a set including one or more downlink-only time slots 852, each downlink-only time slot 852 includes a set including one or more downlink-only codewords; a set including one or more flexible time slots 854, each flexible time slot 854 includes a set including one or more flexible codewords; and a set including one or more uplink-only time slots 856, each uplink-only time slot 856 includes a set including one or more uplink-only codewords. In addition, in some aspects, the control node 810 can configure multiple time slot configuration modes, in which case the multiple time slot configuration modes can be cascaded. In addition, in some aspects, the time slot configuration period can be configured according to other suitable modes.

[0089] Additionally or alternatively, the common TDD configuration may explicitly indicate one or more time slots or symbols configured to support full-duplex communication, and one or more rules may be used to define the placement of full-duplex time slots or symbols within the time slot configuration period (e.g., at the beginning of the time slot configuration period, at the end of the time slot configuration period, or in the middle of the time slot configuration period). Additionally or alternatively, the time slots or symbols configured to support full-duplex communication may be explicitly or implicitly indicated in subsequent (e.g., dedicated) signaling for the wireless node 820.

[0090] For example, in some aspects, the dedicated signaling may include dedicated RRC signaling for the wireless node 820 or a slot format indicator (SFI) carried in downlink control information (DCI). Accordingly, the dedicated RRC signaling may include a dedicated TDD configuration for the wireless node 820, which may override one or more flexible symbols provided by the common TDD configuration. In some examples, the SFI carried in the DCI may include one or more slot format combinations, which may override one or more flexible symbols or dedicated RRC signaling provided by the common TDD configuration (e.g., each slot format combination may include a series of slot formats for several slots). For example, in the dedicated signaling, one or more flexible symbols may be re-marked as downlink symbols, uplink symbols, or full-duplex symbols.

[0091] Accordingly, when symbols configured to support full-duplex communication are explicitly indicated, these symbols may be marked as full-duplex ("FD") in a common TDD configuration, dedicated RRC signaling, or SFI carried in a DCI. For example, to provide backward compatibility, full-duplex symbols may not be indicated in a common TDD configuration that may be received by a legacy UE, child node, or other device lacking full-duplex capability, but may only be explicitly indicated in an SFI carried in a dedicated RRC signaling or DCI for a wireless node 820 with full-duplex capability. Additionally or alternatively, full-duplex symbols may not be indicated in a common TDD configuration or dedicated RRC signaling, but may only be explicitly indicated in an SFI carried in a DCI for a wireless node 820 with full-duplex capability. Additionally or alternatively, in some cases, full-duplex symbols may be explicitly indicated in any of the common TDD configuration for the wireless node 820, dedicated RRC signaling, or the SFI carried in the DCI.

[0092] Additionally or alternatively, dedicated signaling may implicitly indicate one or more symbols that may be used for full-duplex communication. For example, in order to implicitly indicate symbols that may be used for full-duplex communication, dedicated signaling may re-mark downlink symbols as uplink symbols or flexible symbols, or re-mark uplink symbols as downlink symbols or flexible symbols. For example, a common TDD configuration may initially indicate that a symbol is a downlink-only or uplink-only symbol, and dedicated signaling or SFI may re-mark the symbol as an uplink / flexible symbol or a downlink / flexible symbol to implicitly indicate that the symbol is configured for full-duplex communication. In another example, a common TDD configuration or dedicated RRC signaling may initially indicate that a symbol is a downlink-only or uplink-only symbol, and SFI may re-mark the symbol as an uplink / flexible symbol or a downlink / flexible symbol to implicitly indicate that the symbol is configured for full-duplex communication.

[0093] like Figure 8As further indicated in the second operation 860, the wireless node 820 and the wireless node 830 may selectively perform full-duplex or half-duplex operation for scheduled communications based at least in part on the time slot configuration mode indicated in the cell-specific signaling or dedicated signaling. For example, in some aspects, the wireless node 820 may indicate the time slot configuration mode to the wireless node 830 in a manner similar to that described above, and the wireless nodes 820, 830 may be configured to apply one or more rules to determine how to handle scheduled communications based on a combination of parameters provided in the cell-specific signaling or dedicated signaling. For example, if one or more symbols indicated as flexible symbols in the common TDD configuration or dedicated RRC signaling are also indicated as flexible symbols in the SFI, the wireless nodes 820, 830 may cancel the transmission and reception operations for one or more uplink or downlink communications semi-statically configured in such flexible symbols (e.g., via RRC configuration). In this way, by indicating symbols as flexible in multiple signaling messages, the control node 810 can implicitly cancel previously scheduled semi-static communications, which enables these symbols to be used for interference management or power conservation for the wireless node 820 or the wireless node 830 instead. In another example, if one or more symbols are indicated as flexible symbols in the common TDD configuration or dedicated RRC signaling and the wireless node 820 is provided with an SFI indicating these symbols as downlink-only symbols, then the semi-static uplink communication within such symbols can be canceled. Similarly, if the symbols indicated as flexible symbols in the common TDD configuration or dedicated RRC signaling are subsequently indicated as uplink-only symbols in the SFI, then the semi-static downlink communication within such symbols can be canceled.

[0094] In addition, as described herein, the wireless nodes 820, 830 may be configured to apply one or more rules to selectively perform full-duplex operations for communications scheduled on full-duplex codewords, downlink-only codewords, uplink-only codewords, or flexible codewords, and selectively perform half-duplex operations in directions that conflict with the codeword type (e.g., performing uplink communications in codewords scheduled as downlink-only codewords or performing downlink communications in codewords scheduled as uplink-only codewords).

[0095] For example, when full-duplex communication is scheduled in a full-duplex symbol, the wireless node 830 may be configured to simultaneously transmit uplink communications to the wireless node 820 and receive downlink communications from the wireless node 720 for both dynamically scheduled communications and semi-statically scheduled communications. However, in some cases, the full-duplex communication capability may be dynamic or conditional, meaning that the ability of the wireless node 820 or the wireless node 830 to transmit and receive simultaneously may change over time. For example, the wireless node 820 or the wireless node 830 may support full-duplex communication using a first beam pair including a first transmit beam and a first receive beam, but another beam pair including a second transmit beam or a second receive beam may fail to meet one or more conditions (e.g., performance metrics). This may occur due to a cluster echo problem where there may be a strong reflector in a particular beam direction that may cause the transmitted signal to be reflected back to the receive beam. In another example, the ability of the wireless node 820 or the wireless node 830 to perform full-duplex operation may depend on the ability of the wireless node 820 or the wireless node 830 to create simultaneous beams and process transmitted and received signals (e.g., the wireless node 820 or the wireless node 830 may lack the ability to create simultaneous beams and process transmitted and received signals on a single antenna array, but the wireless node 820 or the wireless node 830 may have the ability to create simultaneous beams and process signals transmitted and received from separate arrays or panels). In addition, in another example, the required link budget or the desired transmit or receive power may affect the ability of the wireless node 820 or the wireless node 830 to perform full-duplex operation.

[0096] Accordingly, in the case where the ability of the wireless node 820 or the wireless node 830 to simultaneously transmit and receive in a particular full-duplex symbol fails to meet one or more conditions, the wireless node 820, 830 may selectively perform half-duplex or modified half-duplex communication in the full-duplex symbol according to one or more prioritization rules. For example, in some aspects, if the original symbol type is an uplink symbol that is subsequently re-marked as a downlink or flexible symbol (e.g., the re-marking implicitly indicates a full-duplex symbol), then uplink communication may be given priority. Alternatively, if the original symbol type is a downlink symbol that is subsequently re-marked as an uplink or flexible symbol, then downlink communication may be given priority. In other examples, where the scheduled uplink and downlink communications include a dynamically scheduled communication and a semi-static communication, the dynamically scheduled communication may be given priority, or the priority may be determined at least in part based on the respective times at which the uplink and downlink communications are scheduled (e.g., priority may be given to communications scheduled earlier or communications scheduled later), or the priority may be determined at least in part based on respective signal types associated with the uplink communication and the downlink communication (e.g., prioritizing a downlink SSB over an uplink scheduling request (SR) or a physical uplink shared channel (PUSCH)). Additionally or alternatively, the wireless nodes 820, 830 may apply one or more policies, rules, or internal logic to determine whether to prioritize uplink communications or downlink communications.

[0097] In the above example, the lower priority communication may be canceled or modified, and the wireless node 830 may send an uplink signal to the wireless node 820 to indicate that the lower priority communication is canceled or modified, and the uplink signal may be transmitted before or after the symbol in which the lower priority communication is scheduled. For example, the uplink signal may include uplink control information (UCI) or a media access control (MAC) control element (MAC-CE). In addition, in the case where the lower priority is modified (e.g., the wireless node 830 performs full-duplex operation but modifies one or more communication parameters for the lower priority communication), the uplink signal may indicate the one or more communication parameters modified for the lower priority communication (e.g., reduced transmit power, or changes to the transmit beam or receive beam, etc.).

[0098] In some aspects, when one or more communications are scheduled in an uplink symbol or a downlink symbol, the wireless node 820, 830 may perform the one or more communications based at least in part on the direction of the one or more communications and whether half-duplex operation is scheduled or full-duplex operation is scheduled. For example, if half-duplex uplink communication is scheduled in an uplink symbol or half-duplex downlink communication is scheduled in a downlink symbol, the wireless node 820, 830 may perform half-duplex communication as scheduled. However, if half-duplex communication is scheduled in the direction opposite to the symbol type (e.g., in the case of scheduling uplink communication in a downlink symbol or scheduling downlink communication in an uplink symbol) or full-duplex communication is scheduled in an uplink symbol only or a downlink symbol only, the wireless node 820, 830 may be configured with different behaviors.

[0099] For example, in the case where half-duplex communication is scheduled in the opposite direction to the symbol type, half-duplex communication may be performed only for dynamically scheduled communication. Otherwise, if half-duplex communication is scheduled semi-statically, the half-duplex communication may be canceled. Alternatively, in some aspects, half-duplex communication may be performed for dynamically scheduled communication or semi-statically scheduled communication. Additionally or alternatively, the wireless nodes 820, 830 may apply one or more policies, rules, or internal logic to determine whether to perform half-duplex communication. For example, one or more of the wireless nodes 820, 830 may determine not to perform half-duplex communication in the following circumstances: one or more communications with another node are scheduled, or the conflicting half-duplex communication is scheduled for another purpose (such as obtaining a measurement or performing self-calibration), etc. In such examples, the wireless node 830 may send an uplink signal to the wireless node 820 to indicate whether half-duplex communication is performed, and the uplink signal may be transmitted before or after the symbol that the half-duplex communication is scheduled to perform. For example, the uplink signal may include UCI or MAC-CE, etc.

[0100] In some aspects, in the case where full-duplex communication (including simultaneous uplink and downlink communication) is scheduled in only uplink or only downlink symbols, full-duplex communication may be performed only for dynamically scheduled communication. Alternatively, in some aspects, full-duplex communication may be performed for dynamically scheduled communication or semi-statically scheduled communication. Additionally or alternatively, wireless nodes 820, 830 may selectively perform full-duplex communication depending on whether the simultaneous transmission and reception capabilities meet conditions (e.g., performance metrics related to cluster echo, the ability of wireless nodes 820, 830 to create simultaneous beams and process signals transmitted and received on the same antenna array or different arrays or panels, required link budgets, or desired transmission or reception power, etc.). Accordingly, in the case where the simultaneous transmission and reception capabilities of one or more of the wireless nodes 820, 830 fail to meet the condition, the wireless node 820 or the wireless node 830 may assign a higher priority to the uplink communication or downlink communication. For example, in some aspects, if the symbol is an uplink-only symbol, a higher priority may be given to uplink communications; or if the symbol is a downlink-only symbol, a higher priority may be given to downlink communications. In other examples, where the scheduled uplink and downlink communications include a dynamically scheduled communication and a semi-static communication, a higher priority may be given to the dynamically scheduled communication, or a higher priority may be determined at least in part based on the respective times at which the uplink and downlink communications are scheduled (e.g., a communication scheduled earlier or a communication scheduled later may be given priority), or a higher priority may be determined at least in part based on the respective signal types associated with the uplink communication and the downlink communication (e.g., a downlink SSB is scheduled to take precedence over an uplink SR or PUSCH). Additionally or alternatively, the wireless node 820 or the wireless node 830 may apply one or more policies, rules, or internal logic to determine whether to prioritize uplink communications or downlink communications.

[0101] In the above example, the lower priority communication may be canceled or modified, and the wireless node 830 may send an uplink signal to the wireless node 820 to indicate that the lower priority communication is canceled or modified, and the uplink signal may be transmitted before or after the symbol in which the lower priority communication is scheduled. For example, the uplink signal may include UCI or MAC-CE, etc. In addition, in the case where the lower priority is modified (e.g., the wireless node 830 performs both uplink and downlink communications but modifies one or more communication parameters for the lower priority communication), the uplink signal may indicate the one or more communication parameters modified for the lower priority communication (e.g., reduced transmit power, or changes to the transmit beam or receive beam).

[0102] In some aspects, in the case where full-duplex communication (including simultaneous uplink and downlink communication) is scheduled in a flexible symbol and the control node 810 does not provide an SFI or the SFI provided by the control node 810 also marks the flexible symbol as a flexible symbol, full-duplex communication may be performed for dynamically scheduled communication or semi-statically scheduled communication, or full-duplex communication may be performed only for dynamically scheduled communication. Additionally or alternatively, the wireless nodes 820, 830 may selectively perform full-duplex communication depending on whether the simultaneous transmission and reception capabilities meet the conditions. For example, in the case where the scheduled uplink and downlink communications include a dynamically scheduled communication and a semi-static communication, the dynamically scheduled communication may be given a higher priority, or the higher priority may be determined at least in part based on the respective times at which the uplink and downlink communications are scheduled (e.g., a communication scheduled earlier or a communication scheduled later may be given priority), or the higher priority may be determined at least in part based on the respective signal types associated with the uplink communication and the downlink communication (e.g., a downlink SSB is prioritized over an uplink SR or PUSCH). Additionally or alternatively, in the case where the control node 810 provides an SFI to re-mark a flexible symbol as a downlink-only or uplink-only symbol, if the SFI re-marks the symbol as an uplink-only symbol, the uplink communication may be given a higher priority, or if the SFI re-marks the symbol as a downlink-only symbol, the downlink communication may be given a higher priority. Additionally or alternatively, the wireless node 820, 830 may apply one or more policies, rules, or internal logic to determine whether to prioritize uplink communications or downlink communications.

[0103] In the above example, the lower priority communication may be canceled or modified, and the wireless node 830 may send an uplink signal to the wireless node 820 to indicate that the lower priority communication is canceled or modified, and the uplink signal may be transmitted before or after the symbol in which the lower priority communication is scheduled. For example, the uplink signal may include UCI or MAC-CE, etc. In addition, in the case where the lower priority is modified (e.g., the wireless node 830 performs both uplink and downlink communications, but modifies one or more communication parameters for the lower priority communication), the uplink signal may indicate the one or more communication parameters modified for the lower priority communication (e.g., reduced transmit power, or changes to a transmit beam or a receive beam, etc.).

[0104] Fig. 9 is a flow diagram illustrating an example process 900, performed, for example, by a wireless node, in accordance with various aspects of the present disclosure. The example process 900 is an example of operations in which a wireless node (eg, wireless node 820) performs slot format configuration to support full-duplex operation.

[0105] like Fig. 9 As shown in , in some aspects, process 900 may include receiving information from a control node identifying a time slot configuration mode for a wireless communication link between the wireless node and another wireless node, wherein the information identifying the time slot configuration mode indicates one or more codewords configured to support full-duplex communication (block 910). For example, the wireless node may (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, or controller / processor 280) receive information from a control node identifying a time slot configuration mode for a wireless communication link between the wireless node and another wireless node, as described above. In some aspects, the information identifying the time slot configuration mode indicates one or more codewords configured to support full-duplex communication.

[0106] like Fig. 9 As further shown in FIG. 9 , in some aspects, process 900 may include communicating with the other wireless node in the one or more symbols configured to support full-duplex communication according to the time slot configuration mode (block 920). For example, the wireless node (e.g., 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, or MOD 254) may communicate with the other wireless node in the one or more symbols configured to support full-duplex communication according to the time slot configuration mode, as described above.

[0117] In a tenth additional aspect, either alone or in combination with one or more of the first to ninth aspects, communicating with the other wireless node according to the time slot configuration mode further includes receiving an uplink signal from the other wireless node indicating whether half-duplex operation is performed for the scheduled communication.

[0118] In an eleventh additional aspect, either alone or in combination with one or more of the first to tenth aspects, the information identifying the time slot configuration mode includes a time slot format indicator that changes the label of the codeword from a flexible codeword type to a downlink codeword type or an uplink codeword type.

[0123] although Fig. 9 An example block diagram of process 900 is shown, but in some aspects, process 900 may include Fig. 9 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 900. Additionally or alternatively, two or more blocks of the process 900 may be executed in parallel.

[0124] Fig.10 is a flow diagram illustrating an example process 1000, performed, for example, by a control node, in accordance with various aspects of the present disclosure. The example process 1000 is an example of operations in which a control node (eg, the control node 810) performs configuration of a timeslot format to support full-duplex operation.

[0125] like Fig.10 As shown in , in some aspects, process 1000 may include determining a time slot configuration pattern for a wireless communication link between a wireless node and another wireless node (block 1010). For example, a control node may determine (e.g., using controller / processor 240, or memory 242) a time slot configuration pattern for a wireless communication link between a wireless node and another wireless node, as described above.

[0126] like Fig.10 As further shown in FIG. 1 , in some aspects, process 1000 may include transmitting information identifying the time slot configuration mode for the wireless communication link to the wireless node, wherein the information identifying the time slot configuration mode indicates one or more codewords configured to support full-duplex communication (block 920). For example, the control node may (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, or memory 242) transmit information identifying the time slot configuration mode for the wireless communication link to the wireless node, as described above. In some aspects, the information identifying the time slot configuration mode indicates one or more codewords configured to support full-duplex communication.

[0127] Process 1000 may include additional aspects, such as any single aspect or any combination of aspects described in conjunction with one or more other processes described elsewhere herein.

[0128] although Fig.10 An example block diagram of process 1000 is shown, but in some aspects, process 1000 may include Fig.10 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 1000. Additionally or alternatively, two or more blocks of the process 1000 may be executed in parallel.

[0129] Fig.111 is a block diagram of an example apparatus 1100 for wireless communication in accordance with various aspects of the present disclosure. Apparatus 1100 may be a wireless node, or a wireless node may include apparatus 1100. In some aspects, apparatus 1100 includes a receiving component 1102, a communication manager 1104, and a transmission component 1106, which may communicate with each other (e.g., via one or more buses). As shown, apparatus 1100 may use receiving component 1102 and transmission component 1106 to communicate with another apparatus 1108 (such as a UE, a base station, a control node, or another wireless communication device).

[0130] In some aspects, the apparatus 1100 may be configured to perform Figure 8 Additionally or alternatively, the apparatus 1100 may be configured to perform one or more of the processes described herein (such as Fig. 9 In some aspects, the apparatus 1100 may include the above combined Figure 2 One or more components of a UE or base station are described.

[0131] The receiving component 1102 may receive communications (such as reference signals, control information, data communications, or combinations thereof) from the device 1108. The receiving component 1102 may provide the received communications to one or more other components of the device 1100, such as the communications manager 1104. In some aspects, the receiving component 1102 may perform signal processing (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding, among other examples) on the received communications and may provide the processed signals to one or more other components. In some aspects, the receiving component 1102 may include a combination of the above. Figure 2 One or more antennas, demodulators, MIMO detectors, receive processors, controllers / processors, memories, or combinations thereof of a described UE or base station.

[0132] The transmission component 1106 may transmit communications (such as reference signals, control information, data communications, or a combination thereof) to the device 1108. In some aspects, the communication manager 1104 may generate communications and may transmit the generated communications to the transmission component 1106 for transmission to the device 1108. In some aspects, the transmission component 1106 may perform signal processing (such as filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, encoding, etc.) on the generated communications and may transmit the processed signals to the device 1108. In some aspects, the transmission component 1106 may include the above in combination with Figure 2One or more antennas, modulators, transmit MIMO processors, transmit processors, controllers / processors, memory, or combinations thereof of the described UE or base station. In some aspects, the transmitting component 1106 can be co-located with the receiving component 1102 in a transceiver.

[0133] The communication manager 1104 may receive (or may cause the receiving component 1102 to receive from the control node) information identifying a time slot configuration mode for a wireless communication link between the wireless node and another wireless node from a control node, wherein the information identifying the time slot configuration mode indicates one or more code elements configured to support full-duplex communication. The communication manager 1104 may communicate with the other wireless node in the one or more code elements configured to support full-duplex communication according to the time slot configuration mode. In some aspects, the communication manager 1104 may perform one or more operations performed by one or more components of the communication manager 1104 described elsewhere herein.

[0134] The communication manager 1104 may include the above combination Figure 2 The controller / processor, memory, scheduler, communication unit, or a combination thereof of the wireless node described herein. In some aspects, the communication manager 1104 includes a set of components, such as a prioritization component 1110, a determination component 1112, or a combination thereof. Alternatively, the set of components may be separate and distinct from the communication manager 1104. In some aspects, one or more of the components in the set of components may include or may be combined with the above Figure 2 The described UE or base station controller / processor, memory, scheduler, communication unit or a combination thereof is implemented. Additionally or alternatively, one or more components in the component set may be implemented at least in part as software stored in the memory. For example, a component (or a portion of a component) may be implemented as an instruction or code stored in a non-transitory computer-readable medium and may be executed by a controller or processor to perform the function or operation of the component.
