[0002] This patent application claims priority and benefit to non-provisional patent application No. 17 / 308,548, filed with the U.S. Patent and Trademark Office on May 5, 2021, and provisional patent application No. 63 / 041,774, filed with the U.S. Patent and Trademark Office on June 19, 2020, the entire contents of which are incorporated herein by reference as fully set forth herein and for all applicable purposes. Technical Field

[0003] In summary, the technologies discussed below relate to wireless communication systems, and more specifically, to time-domain and user equipment behavior in full-duplex time-slot formats. Background Technology

[0004] Wireless communication is communicated from a scheduled entity (such as a user equipment (UE) or other wireless communication device) to a scheduling entity (such as a base station) in uplink (UL) transmission, and from the scheduling entity to the scheduled entity in downlink (DL) transmission. Frequency division duplex (FDD) communication allows simultaneous bidirectional communication by separating the frequencies used for uplink (UL) and downlink (DL) transmissions. Separating the frequencies used for UL and DL transmissions allows UL transmissions to be isolated from DL transmissions in the frequency domain. This isolation in the frequency domain reduces interference from the transmitter at the receiver during full-duplex communication switching. Time division duplex (TDD) communication allows non-simultaneous bidirectional communication by using a single set of frequencies for both UL and DL transmissions in the frequency domain, while specifying some time slots for UL transmissions and others for DL ​​communication. In TDD half-duplex communication, UL and DL transmissions occur on the same frequency and are isolated from each other in time. Summary of the Invention

[0005] The following provides an overview of one or more aspects of this disclosure in order to provide a basic understanding of such aspects. This overview is not an exhaustive summary of all the intended features of this disclosure, nor is it intended to identify key or essential elements of all aspects of this disclosure, nor to depict the scope of any or all aspects of this disclosure. Its sole purpose is to present some concepts of one or more aspects of this disclosure in a form as a prelude to the more detailed description given later.

[0006] In one example, a method for wireless communication is disclosed. The method includes: obtaining at a scheduling entity the duplex mode of a scheduled entity that is wirelessly communicating with the scheduling entity; selecting a DU time slot interpretation to be applied by the scheduled entity to time slots including downlink-uplink (DU) symbols based on the duplex mode of the scheduled entity; and sending the DU time slot interpretation to the scheduled entity, wherein the DU symbols are configured to include downlink transmissions and uplink transmissions within the same carrier bandwidth.

[0007] In another example, a scheduling entity in a wireless communication network is disclosed. The scheduling entity includes: a wireless transceiver; a memory; and a processor communicatively coupled to the wireless transceiver and the memory. In this example, the processor and the memory are configured to: obtain the duplex mode of the scheduled entity communicating wirelessly with the scheduling entity; select a DU time slot interpretation to be applied by the scheduled entity to time slots including downlink-uplink (DU) symbols based on the duplex mode of the scheduled entity; and send the DU time slot interpretation to the scheduled entity, wherein the DU symbols are configured to include downlink and uplink transmissions within the same carrier bandwidth.

[0008] According to another aspect, a method for wireless communication is disclosed. The method includes: receiving a message at a scheduling entity, the message indicating that a time slot is formatted to have downlink-uplink (DU) symbols reserved for downlink and uplink transmissions; selecting a DU time slot interpretation to be applied to the time slots including the DU symbols based on the duplex mode of the scheduled entity; and applying the DU time slot interpretation to the time slots, wherein the DU symbols are configured to include downlink and uplink transmissions within the same carrier bandwidth.

[0009] In another example, a scheduling entity in a wireless communication network is disclosed. The scheduling entity includes: a wireless transceiver; a memory; and a processor communicatively coupled to the wireless transceiver and the memory. In this example, the processor and memory are configured to receive messages indicating that time slots are formatted with downlink-uplink (DU) symbols reserved for downlink and uplink transmissions; select DU time slot interpretations to be applied to time slots including DU symbols based on the duplex mode of the scheduled entity; and apply the DU time slot interpretations to the time slots, wherein the DU symbols are configured to include downlink and uplink transmissions within the same carrier bandwidth.

[0030] The detailed description below, taken in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent only the configurations in which the concepts described herein can be practiced. For the purpose of providing a full understanding of the various concepts, the detailed description includes specific details. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

[0031] While aspects and embodiments are described herein by way of example, those skilled in the art will understand that additional implementations and use cases can arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, aspects and / or uses can arise via integrated chip examples and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to a particular use case or application, a wide variety of applicability to the described innovations can emerge. Implementations can range across a spectrum from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating the described aspects and features may also necessary include additional components and features for the implementation and practice of the claimed and described examples. For example, the transmission and reception of wireless signals necessarily involve a number of components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). It is intended that the innovations described herein can be implemented in a wide variety of devices, chip-level components, systems, distributed arrangements, end-user devices, etc., of varying sizes, shapes, and constructions.

[0032] To achieve Frequency Division Duplex (FDD) full-duplex (FD) communication, self-interference from the transmitter of the User Equipment (UE) or base station should be minimized to avoid saturating the sensitive amplifiers and front-ends of the receivers of the UE and base station. To isolate the signal transmitted by the transmitter from the receiver, the frequency band used by the transmitter can be separated from the frequency band used by the receiver. The gap between the two frequency bands can be called a guard band. For Time Division Duplex (TDD) half-duplex (HD) communication, the need for a guard band is eliminated because the transmit and receive frequency bands are the same. Therefore, compared to the FDD FD scheme, the TDD HD scheme uses less bandwidth by using the same sub-channel for transmission and reception at separate times. As used herein, the reference to frequency band can refer to the 5G New Radio (NR) band or NR operating band.

[0033] The simultaneous use of the same set of frequency resources (e.g., the same carrier bandwidth, the same frequency band) for both UL and DL in a given time slot is referred to herein as Subband Full-Duplex (SBFD), also known as Flexible Duplex, in which transmissions in different directions are carried in different subbands or bandwidth portions of the carrier bandwidth or frequency band. Compared to TDD HD, a scheduled entity (e.g., a UE or other wireless communication device) capable of operating in full-duplex mode may be able to use SBFD to increase the amount of data transmitted because, as with FDD FD, data can be transmitted and received simultaneously, while, conversely, data can be transmitted and received in the same carrier bandwidth or frequency band.

[0034] As used herein, the term "duplex mode" refers to the operating mode of a device (e.g., a scheduled entity, UE). Examples of duplex modes can include, but are not limited to, half-duplex (HD), full-duplex (FD), and full-duplex awareness (FD awareness). In half-duplex operation mode, the device can have bidirectional communication (e.g., uplink and downlink), but HD bidirectional communication does not occur simultaneously. Time division duplex (TDD) is an example of an HD system. In full-duplex operation mode, the device can have bidirectional communication, and FD communication can occur simultaneously. This document provides two types of FD communication systems as non-limiting examples; broadly speaking, they can be referred to as paired spectrum and unpaired spectrum FD communication systems. Frequency division duplex (FDD) is an example of a paired spectrum FD system (where uplink and downlink can occur simultaneously in different but paired predefined frequency bands). In-band full-duplex (IBFD) and sub-band full-duplex (SBFD) (also referred to as flexible duplex) are two non-limiting examples of unpaired spectrum FD systems (where uplink and downlink can occur simultaneously in the same frequency band / carrier bandwidth). In FD-aware operating mode, the device can perceive that time-frequency resources can be allocated according to any type of FD communication system; however, the device is not configured as an FD device (e.g., the device is only an HD device). The examples described herein can be interpreted in the context of an SBFD system; however, the use of an SBFD system is exemplary and non-limiting. Other types of unpaired spectrum FD communication systems are within the scope of this disclosure.

[0035] With the deployment of scheduled entities equipped with SBFD capabilities, SBFD-enabled scheduling entities (e.g., gNBs or other radio access network nodes) can provide improved bandwidth utilization for these entities. The scheduling entity can configure time slots (including the OFDM symbol set) for SBFD by configuring frequency resources used for both transmission and reception (e.g., the use of a radio channel in a new radio (NR) operating band currently designated for TDD HD operations). OFDM symbols configured for SBFD purposes can be referred to as downlink-uplink (DU) symbols.

[0036] However, not all scheduled entities will implement SBFD. For example, some scheduled entities may have inexpensive front-ends that include switches that couple antennas to either the scheduled entity's receiver or transmitter, depending on the switch's state. Therefore, such non-SBFD scheduled entities can be configured for either transmitting or receiving, but not both simultaneously. This design minimizes cost and complexity by eliminating relatively expensive and complex multiplexers and / or circulators at the scheduled entity's front-end. The behavior of non-SBFD scheduled entities (non-SBFD UEs) may be undefined. Examples of non-SBFD scheduled entities can include traditional scheduled entities, half-duplex (HD) scheduled entities, and full-duplex aware (FD-aware) scheduled entities.

[0037] Defining the behavior of non-SBFD UEs when encountering DU symbols enables non-SBFD UEs to continue operating in wireless network environments where SBFD transceivers are first used, and prepares for the continued and future use of lower-cost non-SBFD UEs in SBFD environments.

[0038] The various concepts presented throughout this disclosure can be implemented across a wide range of telecommunications systems, network architectures, and communication standards. See now for reference. Figure 1 As an illustrative example and not a limitation, various aspects of this disclosure are shown with reference to a wireless communication system 100. The wireless communication system 100 includes three interaction domains: a core network 102, a radio access network (RAN) 104, and a user equipment (UE) 106. With the wireless communication system 100, the UE 106 may be able to perform data communication with an external data network 110 (such as, but not limited to, the Internet).

[0039] RAN 104 can implement any one or more suitable wireless communication technologies to provide radio access to UE 106. As an example, RAN 104 can operate according to the 3GPP New Radio (NR) specification (often referred to as 5G). As another example, RAN 104 can operate according to a hybrid of 5G NR and the Evolved Universal Terrestrial Radio Access Network (eUTRAN) standard (often referred to as Long Term Evolution (LTE)). 3GPP refers to this hybrid RAN as Next Generation RAN or NG-RAN. Of course, many other examples can be utilized within the scope of this disclosure.

[0040] As shown, RAN 104 includes multiple base stations 108. Broadly speaking, a base station is a network element in a radio access network responsible for radio transmission and reception to or from a UE in one or more cells. In different technologies, standards, or contexts, those skilled in the art may refer to a base station as a base transceiver unit (BTS), radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), access point (AP), node B (NB), eNode B (eNB, evolved Node B), gNode B (gNB), transmit and receive point (TRP), or some other suitable term. In some examples, a base station may include two or more TRPs that may be co-located or non-co-located. Each TRP may communicate on the same or different carrier frequencies within the same or different frequency bands. In an example where RAN 104 operates according to both LTE and 5G NR standards, one base station may be an LTE base station, while the other may be a 5G NR base station.

[0041] RAN 104 also illustrates support for wireless communication for multiple mobile devices. In 3GPP standards, a mobile device may be referred to as a User Equipment (UE), but may also be referred to by those skilled in the art as a Mobile Station (MS), User Station, Mobile Unit, User Unit, Radio Unit, Remote Unit, Mobile Device, Radio Device, Wireless Communication Device, Remote Device, Mobile Subscriber Station, Access Terminal (AT), Mobile Terminal, Radio Terminal, Remote Terminal, Handset, Terminal, User Agent, Mobile Client, Client, or any other suitable term. A UE may be a means (e.g., a mobile device) that provides users with access to network services.

[0042] Within the scope of this disclosure, a "mobile" device does not necessarily need to be capable of movement and can be stationary. The term mobile device or mobile equipment broadly refers to a wide variety of devices and technologies. A UE may include a number of hardware structural components that are sized, shaped, and arranged to facilitate communication; such components may include electrically coupled antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc. For example, some non-limiting examples of mobile devices include mobile stations, cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptop computers, personal computers (PCs), notebooks, netbooks, smartbooks, tablet devices, personal digital assistants (PDAs), and a wide variety of embedded systems, for example, corresponding to the "Internet of Things" (IoT).

[0043] Mobile devices can additionally include automobiles or other vehicles, remote sensors or actuators, robots or robotic devices, satellite radio units, Global Positioning System (GPS) devices, object tracking devices, drones, multi-rotor helicopters, quadcopter helicopters, remote control devices, consumer and / or wearable devices (such as glasses, wearable cameras, virtual reality devices, smartwatches, health or fitness trackers, digital audio players (e.g., MP3 players), cameras, game consoles, etc.). Mobile devices can additionally include digital home or smart home devices, such as home audio, video and / or multimedia equipment, appliances, vending machines, smart lighting, home security systems, smart meters, etc. Mobile devices can additionally include smart energy devices, security devices, solar panels or solar arrays, municipal infrastructure equipment for controlling electricity (e.g., smart grids), lighting, water, etc., industrial automation and enterprise equipment, logistics controllers and / or agricultural equipment, etc. Furthermore, mobile devices can be used for connected medical or telemedicine support (e.g., telehealth). Telemedicine devices may include telemedicine monitoring devices and telemedicine management devices, whose communications may be given priority processing or access relative to other types of information, for example, priority access for the transmission of critical service data, and / or QoS related to the transmission of critical service data.

[0044] Wireless communication between RAN 104 and UE 106 can be described as utilizing an air interface. Transmissions over the air interface from a base station (e.g., base station 108) to one or more UEs (e.g., similar to UE 106) can be referred to as downlink (DL) transmissions. According to certain aspects of this disclosure, the term downlink can refer to point-to-multipoint transmissions originating at the base station (e.g., base station 108). Another way to describe this scheme is to use the term broadcast channel multiplexing. Transmissions from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmissions. According to a further aspect of this disclosure, the term uplink can refer to point-to-point transmissions originating at the UE (e.g., UE 106).

[0045] In some examples, access to the air interface can be scheduled, where a scheduling entity (e.g., base station 108) allocates resources for communication among some or all equipment and apparatus within its service area or cell. Within this disclosure, as further discussed below, the scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more scheduled entities (e.g., UE 106). That is, for scheduled communication, multiple UEs 106 (which may be scheduled entities) can utilize the resources allocated by the scheduling entity 108.

[0046] Base station 108 is not the only entity that can act as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity, scheduling resources for one or more scheduled entities (e.g., one or more other UEs). For example, a UE can communicate directly with other UEs in a peer-to-peer or device-to-device manner and / or in a relay configuration.

[0047] like Figure 1 As shown, scheduling entity 108 can broadcast downlink service 112 to one or more scheduled entities (e.g., one or more UEs 106). In a broader sense, scheduling entity 108 is a node or device responsible for scheduling services (including downlink service 112, and in some examples, uplink service 116 from one or more scheduled entities (e.g., one or more UEs 106) to scheduling entity 108) in a wireless communication network. On the other hand, a scheduled entity (e.g., UE 106) is a node or device that receives downlink control information 114 (including, but not limited to, scheduling information (e.g., permission), synchronization or timing information, or other control information) from another entity in the wireless communication network (such as scheduling entity 108).

[0048] Additionally, uplink and / or downlink control information and / or service information can be transmitted on a waveform that can be time-divided into frames, subframes, time slots, and / or symbols. As used herein, a symbol can refer to a time unit carrying one resource element (RE) per subcarrier in an Orthogonal Frequency Division Multiplexing (OFDM) waveform. A time slot can carry 7 or 14 OFDM symbols. A subframe can refer to a duration of 1 ms. Multiple subframes or time slots can be grouped together to form a single frame or radio frame. Within this disclosure, a frame can refer to a predetermined duration (e.g., 10 ms) for wireless transmission, where each frame comprises, for example, 10 subframes (each subframe 1 ms). Of course, these definitions are not mandatory, and any suitable scheme for organizing the waveform can be utilized, and various time divisions of the waveform can have any suitable duration.

[0049] Typically, base station 108 may include a backhaul interface for communication with the backhaul portion 120 of wireless communication system 100. Backhaul portion 120 may provide a link between base station 108 and core network 102. Further, in some examples, the backhaul network may provide interconnection between the respective base stations 108. Various types of backhaul interfaces may be employed, such as direct physical connections, virtual networks, or backhaul interfaces using any suitable transport network.

[0050] Core network 102 may be part of wireless communication system 100 and may be independent of the radio access technology used in RAN 104. In some examples, core network 102 may be configured according to 5G standards (e.g., 5GC). In other examples, core network 102 may be configured according to 4G Evolved Packet Core (EPC) or any other suitable standard or configuration.

[0051] Now refer to Figure 2 The schematic diagram of a radio access network (RAN) 200 according to some aspects of this disclosure is provided as an illustrative example and not as a limitation. In some examples, the RAN 200 may be integrated with the network described above and in... Figure 1 The same as RAN 104 shown in the figure.

[0052] The geographical area covered by RAN 200 can be divided into a number of cellular areas (cells), which can be uniquely identified by user equipment (UE) based on an identifier broadcast from an access point or base station in the geographical area. Figure 2 Cells 202, 204, 206, and 208 are shown, each of which may include one or more sectors (not shown). A sector is a sub-area of ​​a cell. All sectors within a cell are served by the same base station. Radio links within a sector can be identified by a single logical identifier belonging to that sector. In a cell divided into sectors, multiple sectors within the cell can be formed by multiple sets of antennas, each responsible for communicating with UEs within a portion of the cell.

[0053] Various base stations can be used for deployment. For example, in Figure 2 In this example, two base stations (base station 210 and base station 212) are shown in cells 202 and 204. A third base station (base station 214) is shown as a remote radio head (RRH) 216 controlled in cell 206. That is, the base station may have an integrated antenna, or it may be connected to an antenna or RRH 216 via a feeder cable. In the example shown, cells 202, 204, and 206 can be referred to as macro cells because base stations 210, 212, and 214 support cells with large sizes. Further, base station 218 is shown in cell 208, which may overlap with one or more macro cells. In this example, cell 208 can be referred to as a small cell (e.g., small cell, microcell, picocell, femtocell, home base station, home node B, home eNode B, etc.) because base station 218 supports cells with relatively small sizes. Cell size settings can be made based on system design and component constraints.

[0054] It is important to understand that RAN 200 can include any number of radio base stations and cells. Furthermore, relay nodes can be deployed to extend the size or coverage area of ​​a given cell. Base stations 210, 212, 214, and 218 provide radio access points to the core network for any number of mobile devices. In some examples, base stations 210, 212, 214, and / or 218 can be used in conjunction with those described above and in... Figure 1 The scheduling entity 108 shown is the same as or similar to that shown.

[0055] Figure 2 This also includes an unmanned aerial vehicle (UAV) 220, which can be a drone or a quadcopter. The UAV 220 can be configured to act as a base station, or more specifically, as a mobile base station. That is, in some examples, the cell may not necessarily be stationary, and the geographical area of ​​the cell can move depending on the location of the mobile base station (such as the UAV 220).

[0056] Within RAN 200, a cell may include UEs capable of communicating with one or more sectors of each cell. Further, each base station 210, 212, 214, 218, and 220 may be configured to provide access to the core network 102 (see [link to core network]) to all UEs in their respective cells. Figure 1 Access points. For example, UEs 222 and 224 can communicate with base station 210; UEs 226 and 228 can communicate with base station 212; UEs 230 and 232 can communicate with base station 214 via RRH 216; UE 234 can communicate with base station 218; and UE 236 can communicate with mobile base station 220. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 236, 238, 240, and / or 242 can communicate with the access points described above and in... Figure 1 The UE / scheduled entity 106 shown is the same as or similar to that shown. In some examples, the UAV 220 (e.g., a quadcopter) can be a mobile network node and can be configured to act as a UE. For example, the UAV 220 can operate within cell 202 by communicating with base station 210.

[0057] In a further aspect of RAN 200, sidelink signals can be used between UEs without relying on scheduling or control information from the base station. Sidelink communication can be utilized in device-to-device (D2D) networks, peer-to-peer (P2P) networks, vehicle-to-vehicle (V2V) networks, vehicle-to-everything (V2X) networks, and / or other suitable sidelink networks. For example, two or more UEs (e.g., UEs 238, 240, and 242) can communicate with each other using sidelink signal 237 without relaying the communication through a base station. In some examples, UEs 238, 240, and 242 can each act as a scheduling entity or a transmitting sidelink device and / or a scheduled entity or a receiving sidelink device to schedule resources and transmit sidelink signal 237 between them, without relying on scheduling or control information from the base station. In other examples, two or more UEs (e.g., UEs 226 and 228) within the coverage area of ​​a base station (e.g., base station 212) can also transmit sidelink signals 227 via a direct link (sidelink) without transmitting the communication through base station 212. In this example, base station 212 can allocate resources for sidelink communication to UEs 226 and 228.

[0058] To achieve a low block error rate (BLER) while still maintaining a very high data rate over an air interface, channel coding can be used. That is, wireless communication can typically utilize appropriate error-correcting block codes. In a typical block code, the information message or sequence is divided into code blocks (CBs), and an encoder (e.g., CODEC) at the transmitting device then mathematically adds redundancy to the information message. Utilizing this redundancy in the encoded information message improves message reliability and allows for correction of any bit errors that may occur due to noise.

[0059] Data encoding can be implemented in several ways. In early 5G NR specifications, user data was encoded using quasi-cyclic low-density parity-check (LDPC) with two different base maps: one base map was used for large code blocks and / or high code rates, while the other base map was used otherwise. Control information and the Physical Broadcast Channel (PBCH) were encoded using polar coding based on nested sequences. For these channels, puncturing, shortening, and repetition were used for rate matching.

[0060] Various aspects of this disclosure can be implemented using any suitable channel code. Various implementations of the base station and UE may include appropriate hardware and capabilities (e.g., encoders, decoders, and / or CODECs) for wireless communication using one or more channels of these channel codes.

[0061] In RAN 200, the ability of a UE to communicate while moving (independent of its location) is called mobility. The various physical channels between the UE and RAN 200 are typically established, maintained, and released under the control of the Access and Mobility Management Function (AMF). In some scenarios, the AMF may include a Security Context Management Function (SCMF) and a Security Anchor Function (SEAF) that performs authentication. The SCMF can manage the security context for both control plane and user plane functions, either wholly or partially.

[0062] In various aspects of this disclosure, RAN 200 can utilize DL-based mobility or UL-based mobility to achieve mobility and handover (i.e., the transfer of UE connectivity from one radio channel to another). In a network configured for DL-based mobility, during a call with a scheduling entity, or at any other time, the UE can monitor various parameters of the signal from its serving cell and various parameters of neighboring cells. Depending on the quality of these parameters, the UE can maintain communication with one or more neighboring cells. During this time, if the UE moves from one cell to another, or if the signal quality from a neighboring cell exceeds the signal quality from the serving cell for a given amount of time, the UE can undertake a handoff or handover from the serving cell to a neighboring (target) cell. For example, UE 224 can move from a geographic area corresponding to its serving cell 202 to a geographic area corresponding to a neighboring cell 206. When the signal strength or quality from the neighboring cell 206 exceeds the signal strength or quality from its serving cell 202 for a given amount of time, UE 224 can send a report message to its serving base station 210 indicating this situation. In response, UE 224 can receive a handover command, and the UE can undergo a handover to cell 206.

[0063] In a network configured for UL-based mobility, the UL reference signal from each UE can be used by the network to select a serving cell for each UE. In some examples, base stations 210, 212, and 214 / 216 can broadcast uniform synchronization signals (e.g., a uniform primary synchronization signal (PSS), a uniform secondary synchronization signal (SSS), and a uniform physical broadcast channel (PBCH)). UEs 222, 224, 226, 228, 230, and 232 can receive the uniform synchronization signal, derive carrier frequency and time slot timing based on the synchronization signal, and transmit uplink pilots or reference signals in response to the derived timing. The uplink pilot signal transmitted by a UE (e.g., UE 224) can be received concurrently by two or more cells (e.g., base stations 210 and 214 / 216) within RAN 200. Each cell in the RAN can measure the strength of the pilot signal, and the radio access network (e.g., base stations 210 and 214 / 216 and / or one or more of the central nodes in the core network) can determine the serving cell for UE 224. As UE 224 moves through RAN 200, RAN 200 can continue to monitor the uplink pilot signal transmitted by UE 224. When the signal strength or quality of the pilot signal measured by a neighboring cell exceeds the signal strength or quality measured by the serving cell, RAN 200 can, with or without notifying UE 224, hand over UE 224 from the serving cell to a neighboring cell.

[0064] While the synchronization signals transmitted by base stations 210, 212, and 214 / 216 can be uniform, they may not identify a specific cell but rather an area of ​​multiple cells operating on the same frequency and / or using the same timing. The use of areas in 5G networks or other next-generation communication networks enables an uplink-based mobility framework and improves the efficiency of both the UE and the network by reducing the number of mobility messages that need to be exchanged between the UE and the network.

[0065] In various implementations, the air interface in the radio access network 200 can utilize licensed spectrum, unlicensed spectrum, or shared spectrum. Licensed spectrum typically prepares for exclusive use of a portion of the spectrum by requiring a license purchased by the mobile network operator from a government regulatory agency. Unlicensed spectrum prepares for shared use of a portion of the spectrum without requiring a government-approved license. While some technical rules are generally still required to access unlicensed spectrum, access is usually available to any operator or device. Shared spectrum can fall between licensed and unlicensed spectrum, where some technical rules or restrictions may be required to access the spectrum, but the spectrum can still be shared by multiple operators and / or multiple RATs. For example, a licensee for a portion of licensed spectrum can provide Licensed Shared Access (LSA) to share the spectrum with other parties (e.g., those with appropriate licensee-defined conditions for access).

[0066] Devices communicating in the radio access network 200 can utilize one or more multiplexing techniques and multiple access algorithms to achieve simultaneous communication between various devices. For example, the 5G NR specification provides multiple access for UL transmissions from UEs 222 and 224 to base station 210, and multiplexing for DL ​​transmissions from base station 210 to one or more UEs 222 and 224 using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP). Additionally, for UL transmissions, the 5G NR specification provides support for Discrete Fourier Transform Extended OFDM (DFT-s-OFDM) with CP (also known as Single-Carrier FDMA (SC-FDMA)). However, within the scope of this disclosure, multiplexing and multiple access are not limited to the above schemes and can be provided using Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Sparse Code Multiple Access (SCMA), Resource Extended Multiple Access (RSMA), or other suitable multiple access schemes. Furthermore, the multiplexing of DL transmission from base station 210 to UEs 222 and 224 can be provided using time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code multiplexing (SCM), or other appropriate multiplexing schemes.

[0067] Devices in the radio access network 200 can also utilize one or more duplex algorithms. Duplex refers to a point-to-point communication link where two endpoints can communicate with each other in both directions. Full-duplex means that two endpoints can communicate with each other simultaneously. Half-duplex means that only one endpoint can send information to the other endpoint at any given time. Half-duplex simulation is frequently implemented for wireless links using Time Division Duplex (TDD). In TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, in some scenarios, the channel is dedicated to transmission in one direction, while at other times, the channel is dedicated to transmission in the other direction, where the direction can change very rapidly, for example, several times per time slot. In wireless links, full-duplex channels typically rely on physical isolation between the transmitter and receiver, as well as appropriate interference cancellation techniques. Full-duplex simulation is frequently implemented for wireless links using Frequency Division Duplex (FDD) or Space Division Duplex (SDD). In FDD, transmissions in different directions can operate at different carrier frequencies (e.g., within paired spectrum). In SDD, transmissions in different directions on a given channel are separated from each other using spatial division multiplexing (SDM). In other examples, full-duplex communication can be implemented in unpaired spectrum (e.g., within a single carrier bandwidth), where transmissions in different directions occur within different subbands of the carrier bandwidth. This type of full-duplex communication may be referred to herein as Subband Full-Duplex (SBFD), also known as Flexible Duplex.

[0068] All aspects of this disclosure will be for reference (in) Figure 3 The OFDM waveform is illustrated schematically in the diagram. Those skilled in the art will understand that various aspects of this disclosure can be applied to SC-FDMA waveforms in substantially the same manner as described below. That is, while some examples of this disclosure may focus on OFDM links for clarity, it should be understood that the same principles can also be applied to SC-FDMA waveforms.

[0069] Now for reference Figure 3 The diagram shows an expanded view of exemplary subframe 302, illustrating an OFDM resource grid according to some aspects of this disclosure. However, as those skilled in the art will readily recognize, the physical (PHY) transmission structure for any particular application can differ from the example described herein, depending on any number of factors. Here, time is in the horizontal direction, in OFDM symbols; and frequency is in the vertical direction, in subcarriers of a carrier.

[0070] Resource grid 304 can be used to schematically represent time-frequency resources for a given antenna port. That is, in a multiple-input multiple-output (MIMO) implementation with multiple available antenna ports, a corresponding multiple of resource grids 304 can be available for communication. Resource grid 304 is divided into multiple resource elements (REs) 306. An RE (which is 1 subcarrier × 1 symbol) is the smallest discrete part of the time-frequency grid and contains a single complex value representing data from a physical channel or signal. Depending on the transmit and receive schemes used in a particular implementation, each RE can represent one or more bits of information. In some examples, a block of REs may be called a physical resource block (PRB) or more simply a resource block (RB) 308, which contains any appropriate number of consecutive subcarriers in the frequency domain. In one example, an RB may include 12 subcarriers, the number of which is independent of the numerology used. In some examples, depending on the numerology, an RB may include any appropriate number of consecutive OFDM symbols in the time domain. Within this disclosure, it is assumed that a single RB (such as RB 308) corresponds entirely to a single direction of communication (the direction of transmission or reception for a given device).

[0071] A set of contiguous or discontinuous resource blocks may be referred to herein as a resource block group (RBG), subband, or bandwidth portion (BWP). A set of subbands or BWPs can span the entire bandwidth. Scheduling of a scheduled entity (e.g., a UE) for downlink, uplink, or sidelink transmission typically involves scheduling one or more resource elements 306 within one or more subbands or bandwidth portions (BWPs). Therefore, a UE typically utilizes only a subset of the resource grid 304. In some examples, an RB may be the smallest unit of resources that can be allocated to a UE. Therefore, the more RBs scheduled for a UE, and the higher the modulation scheme selected for the air interface, the higher the data rate for the UE. RBs can be scheduled by a scheduling entity (such as a base station (e.g., gNB, eNB, etc.)) or can be scheduled by the UE implementing D2D sidelink communication.

[0072] In this illustration, RB 308 is shown occupying less than the entire bandwidth of subframe 302, with some subcarriers shown above and below RB 308. In a given implementation, subframe 302 can have a bandwidth corresponding to any number of one or more RB 308s. Furthermore, in this illustration, RB 308 is shown occupying less than the entire duration of subframe 302; however, this is merely one possible example.

[0073] Each 1ms subframe 302 may include one or more adjacent time slots. Figure 3In the example shown, a subframe 302 includes four time slots 310, as an illustrative example. In some examples, time slots may be defined based on a specified number of OFDM symbols with a given cyclic prefix (CP) length. For example, a time slot may include 7 or 14 OFDM symbols with a nominal CP. Other examples may include micro-time slots with shorter durations (e.g., one to three OFDM symbols), sometimes referred to as shortened transmission time intervals (TTIs). In some cases, these micro-time slots or shortened transmission time intervals (TTIs) may be transmitted by preempting resources scheduled for ongoing time slot transmissions for the same or different UEs. Any number of resource blocks can be utilized within a subframe or time slot.

[0074] An expanded view of time slot 310 shows that time slot 310 includes a control region 312 and a data region 314. Typically, control region 312 can carry a control channel, and data region 314 can carry a data channel. Of course, a time slot can contain all DL, all UL, or at least one DL portion and at least one UL portion. Figure 3 The structure shown is merely exemplary in nature, and different time slot structures can be utilized, and different time slot structures can include one or more regions of each of the control region and the data region.

[0075] Despite Figure 3 Although not shown, each RE 306 within RB 308 can be scheduled to carry one or more physical channels, including control channels, shared channels, data channels, etc. Other REs 306 within RB 308 can also carry pilot or reference signals. These pilot or reference signals can prepare the receiving device for channel estimation of the corresponding channels, which enables coherent demodulation / detection of the control and / or data channels within RB 308.

[0076] In some examples, time slot 310 can be used for broadcast, multicast, or unicast communications. For example, broadcast, multicast, or multicast communications can refer to point-to-multipoint transmission from one device (e.g., a base station, UE, or other similar device) to other devices. Here, broadcast communications are delivered to all devices, while multicast or multicast communications are delivered to multiple intended receiving device devices. Unicast communications can refer to point-to-point transmission from one device to a single other device.

[0077] In an example of cellular communication over a cellular carrier via the Uu interface, for DL ​​transmission, a scheduling entity (e.g., a base station) may allocate one or more REs 306 (e.g., within control area 312) to one or more scheduled entities (e.g., UEs) to carry DL control information including one or more DL control channels (such as the Physical Downlink Control Channel (PDCCH)). The PDCCH carries downlink control information (DCI), including, but not limited to, power control commands (e.g., one or more open-loop power control parameters and / or one or more closed-loop power control parameters), scheduling information, permission, and / or assignment of REs for DL ​​and UL transmissions. The PDCCH may also carry Hybrid Automatic Repeat Request (HARQ) feedback transmissions, such as acknowledgment (ACK) or negative acknowledgment (NACK). HARQ is a technique well known to those skilled in the art, where the integrity of packet transmissions can be verified at the receiving end for accuracy, for example, using any suitable integrity verification mechanism, such as checksum or cyclic redundancy check (CRC). If the integrity of the transmission is acknowledged, an ACK can be sent; otherwise, a NACK can be sent. In response to NACK, the transmitting device can send HARQ retransmissions, which can implement append merging, incremental redundancy, etc.

[0078] The base station can also allocate one or more REs 306 (e.g., in control area 312 or data area 314) to carry other DL signals, such as demodulation reference signals (DMRS); phase tracking reference signals (PT-RS); channel state information (CSI) reference signals (CSI-RS); and synchronization signal blocks (SSBs). SSBs can be broadcast at regular intervals based on a period (e.g., 5, 10, 20, 30, 80, or 130 ms). SSBs include the primary synchronization signal (PSS), secondary synchronization signal (SSS), and physical broadcast control channel (PBCH). The UE can utilize the PSS and SSS to achieve radio frame, subframe, time slot, and symbol synchronization in the time domain, identify the center of the channel (system) bandwidth in the frequency domain, and identify the physical cell identifier (PCI) of the cell.

[0079] The PBCH in the SSB may also include a Master Information Block (MIB) (which contains various system information) along with parameters used to decode the System Information Block (SIB). For example, the SIB may be System Information Type 1 (SIB1), which may include various additional system information. Together, the MIB and SIB1 provide the minimum system information (SI) for initial access. Examples of system information transmitted in the MIB may include, but are not limited to, subcarrier spacing (e.g., the default downlink digital scheme), system frame number, configuration of the PDCCH control resource set (CORESET) (e.g., PDCCHCORESET0), cell prohibition indicator, cell reselection indicator, raster offset, and search space for SIB1. Examples of residual minimum system information (RMSI) transmitted in SIB1 may include, but are not limited to, random access search space, paging search space, downlink configuration information, and uplink configuration information. The base station may also transmit other system information (OSI).

[0080] In UL transmissions, the scheduled entity (e.g., the UE) may utilize one or more RE 306s to carry UL control information (UCI) to the scheduling entity, including one or more UL control channels (such as the Physical Uplink Control Channel (PUCCH)). UCIs can include a wide variety of packet types and categories, including pilots, reference signals, and information configured to enable or assist in decoding uplink data transmissions. Examples of uplink reference signals may include sounding reference signals (SRS) and uplink DMRS. In some examples, the UCI may include a scheduling request (SR), i.e., a request to the scheduling entity to schedule uplink transmissions. Here, in response to an SR transmitted on the UCI, the scheduling entity may send downlink control information (DCI), which can schedule resources for uplink packet transmissions. UCIs may also include HARQ feedback, channel state feedback (CSF) (such as CSI reports), or any other suitable UCI.

[0081] In addition to control information, one or more REs 306 (e.g., within data area 314) can be allocated for data. Such data can be carried on one or more traffic channels (e.g., a Physical Downlink Shared Channel (PDSCH) for DL ​​transmissions; or a Physical Uplink Shared Channel (PUSCH) for UL transmissions). In some examples, one or more REs 306 within data area 314 can be configured to carry other signals (such as one or more SIBs and DMRS).

[0082] In an example of sidelink communication on a sidelink carrier via the Proximity Service (ProSe) PC5 interface, the control area 312 of time slot 310 may include a Physical Sidelink Control Channel (PSCCH), which includes sidelink control information (SCI) transmitted by an initiating (transmitting) sidelink device (e.g., a Tx V2X device or other Tx UE) toward a set of one or more other receiving sidelink devices (e.g., Rx V2X devices or other Rx UEs). The data area 314 of time slot 310 may include a Physical Sidelink Shared Channel (PSSCH), which includes sidelink data transmitted by the initiating (transmitting) sidelink device within resources reserved on the sidelink carrier via the SCI. Other information may also be transmitted on each RE 306 within time slot 310. For example, HARQ feedback information can be transmitted from the receiving sidelink device to the transmitting sidelink device in the Physical Sidelink Feedback Channel (PSFCH) within time slot 310. Additionally, one or more reference signals (such as sidelink SSB, sidelink CSI-RS, sidelink SRS, and / or sidelink Positioning Reference Signal (PRS)) can be transmitted within time slot 310.

[0083] The physical channels described above are typically multiplexed and mapped to transport channels for processing at the Media Access Control (MAC) layer. The transport channels carry blocks of information called transport blocks (TBs). The transport block size (TBS) (which can correspond to the number of bits of information) can be a controlled parameter based on the modulation and coding scheme (MCS) and the number of redundancies (RBs) in a given transmission.

[0084] exist Figure 3 The channels or carriers shown are not necessarily all of the channels or carriers that can be used between devices, and those skilled in the art will recognize that other channels or carriers, such as other service, control, and feedback channels, may be used in addition to the channels or carriers shown.

[0085] Figure 4A , Figure 4B and Figure 4C This is a schematic diagram of a wireless communication network 400 according to some aspects of this disclosure, and interference sources targeting a full-duplex gNB 402 (e.g., a scheduling entity), a half-duplex UE 406, a first full-duplex UE 412, and a second full-duplex UE 408. Figure 4AIn the diagram, full-duplex gNB 402 is transmitting to half-duplex UE 406. During the transmission time from full-duplex gNB 402 to half-duplex UE 406, full-duplex gNB 402 receives self-interference 410 from its own transmission to half-duplex UE 406, as well as interference from neighboring gNB 404 and uplink transmission from second full-duplex UE 408 at its receiver (not shown). Half-duplex UE 406 also receives interference from second full-duplex UE 408 and neighboring gNB 404. Because it is a half-duplex UE, half-duplex UE 406 does not transmit during the transmission time from full-duplex gNB 402 to half-duplex UE 406, and therefore, half-duplex UE 406 does not receive self-interference.

[0086] exist Figure 4B In this configuration, full-duplex gNB 402 transmits downlink data to the first full-duplex UE 412. During the downlink transmission from full-duplex gNB 402 to the first full-duplex UE 412, full-duplex gNB 402 simultaneously receives uplink data from the first full-duplex UE 412 at its receiver (not shown). Simultaneously with the aforementioned downlink and uplink transmissions, the first full-duplex UE 412 receives self-interference 414 from its own transmission to full-duplex gNB 402, as well as interference from the neighboring gNB 404 and interference from the second full-duplex UE 408 at its receiver (not shown).

[0087] exist Figure 4C In this configuration, the full-duplex gNB 402 receives uplink transmissions from the first full-duplex UE 412. During the transmission time of the uplink transmission to the full-duplex gNB 402, the first full-duplex UE 412 also receives transmissions from multiple transmit and receive point (TRP) stations (e.g., macro cells, small cells, pico cells, femtocells, remote radio heads, relay nodes, etc.) (here indicated as multiple TRP transceiver station 418). In addition to the signals received from the multiple TRP transceiver station 418, the first full-duplex UE 412 also receives self-interference 416 at its receiver (not shown) from its own transmissions to the full-duplex gNB 402.

[0088] for Figure 4A For half-duplex UE 406, interference from neighboring gNB 404 and the second full-duplex UE 408 can be mitigated if it occurs at a frequency other than that occupied by downlink transmissions from full-duplex gNB 402 to half-duplex UE 406. Similarly, for Figure 4B and Figure 4CThe interference of the first full-duplex UE 412 can be mitigated if the self-interference 416 from the first full-duplex UE 412, the interference from the neighboring gNB 404, and / or the interference from the second full-duplex UE 408 are at frequencies other than those occupied by the downlink transmission from the full-duplex gNB 402 to the half-duplex UE 406.

[0089] Figure 5A Table 500 is a table depicting several new radio (NR) operating bands 502 (e.g., radio channels) according to some aspects of this disclosure, UL operating band frequencies 504, DL operating band frequencies 506, and duplex modes 508 associated with each NR operating band 502.

[0090] Figure 5B This is a schematic diagram illustrating some aspects of FDD scheme 510 according to this disclosure. Figure 5B In the example shown, time is represented along the horizontal axis, while frequency is represented along the vertical axis. Multiple Physical Uplink Shared Channel (PUSCH) 512 and Uplink Control Channel 514 are depicted as occupancy identifiable as nx UL. FDD The UL operating frequency band. Multiple downlink data channels 516 (e.g., Physical Downlink Shared Channel (PDSCH)) and downlink control channel 518 are depicted as occupancy identifiable by nx DL. FDD The DL operating frequency band. The UL operating frequency band nx UL FDD and DL operating frequency band nx DL FDD Described as being separated by a guard band of 520 in frequency. For a given NX operating frequency band, the NX UL... FDD Uplink operating frequency band and nx DL FDD The paired use of operating frequency bands can be referred to as paired spectrum. The nomenclature "nx" indicates either of the NR operating frequency bands 502 designated for FDD duplex mode 508. Figure 5A The text indicates that all NR operating frequency bands 502 are designated as subgroups 522 for FDD duplex mode 508. The operating frequency bands are exemplary and non-limiting.

[0091] Figure 5C This is a schematic diagram illustrating some aspects of the TDD scheme 530 according to this disclosure. Figure 5C In the example shown, time is represented along the horizontal axis, while frequency is represented along the vertical axis. Multiple downlink data channels 532 and downlink control channels 534 are depicted as occupancy identifiable as ny UL&DL. TDDThe operating frequency band. By separating UL and DL information in time (e.g., they do not occupy the same time slot simultaneously), a single operating frequency band, nyUL&DL, is utilized for both uplink and downlink. TDD For nx UL FDD Uplink operating frequency band and nx DL FDD The unpaired use of operating frequency bands (both at the same frequency band in a given nx operating frequency band) can be referred to as unpaired spectrum. The Physical Uplink Shared Channel (PUSCH) 538 and Uplink Control Channel 536 are depicted as occupying a single operating frequency band ny UL&DL. TDD The naming convention "ny" indicates any of the NR operating bands 502 designated for TDD duplex mode 508. Figure 5A The term 523 represents the subgroup 523 designated for TDD duplex mode within all NR operating frequency bands 502. The operating frequency bands are exemplary and non-limiting.

[0092] Figure 5D This is a schematic diagram illustrating some aspects of SBFD scheme 540 according to this disclosure. Figure 5D In the example shown, time is represented along the horizontal axis, while frequency is represented along the vertical axis. (As in...) Figure 5D As shown in the exemplary figure, full-duplex networks can utilize SBFD (e.g., as...) in unpaired spectrum. Figure 6B As shown), transmissions in different directions are carried in different subbands or BWPs of the carrier bandwidth (e.g., frequency bands). Multiple downlink data channels 544 and downlink control channels 542, as well as multiple PUSCH 546 and uplink control channels 548, are all depicted as occupancy identifiers nz UL&DL. FD The operating frequency band. A single operating frequency band (nz UL&DL) is used for both uplink and downlink. FD Instead of separating UL and DL information in time (e.g., they occupy the same time slot simultaneously), the naming convention "nz" indicates either of the NR operating bands 502 designated for TDD duplex mode 508. Figure 5A The term 523 represents the subgroup 523 designated for TDD duplex mode 508 within all NR operating frequency bands 502. Figure 5D The first guard band 550 and the second guard band 552 are depicted. The first guard band 550 and the second guard band 552 may have the same bandwidth or different bandwidths. Either or both of the first guard band 550 and the second guard band 552 may be a zero-bandwidth guard band. The first guard band 550 and the second guard band 552 (alone or together) in the unpaired spectrum may be smaller than the guard band 520 in the paired spectrum.

[0093] Figures 6A-6C This illustrates full-duplex communication in unpaired spectrum. Figures 6A-6C In the example shown, time is in the horizontal direction, while frequency is in the vertical direction. Here, carrier bandwidth 602 (or a set of one or more active bandwidth portions (BWPs)) is shown along the frequency axis, and time slot 604 is shown along the time axis.

[0094] Figure 6A and Figure 6B This illustrates in-band full-duplex (IBFD) communication, while Figure 6C This illustrates sub-band FD communication. For IBFD communication, as shown... Figure 6A and Figure 6B As shown, downlink and uplink transmissions occur on the same time and frequency resources. For example, downlink resource 606 allocated for downlink transmission overlaps with uplink resource 608 allocated for uplink transmission in both time and frequency. The overlap can be complete (e.g., ...). Figure 6A (as shown) or part of (e.g.) Figure 6B (As shown).

[0095] For sub-band FD communication, such as Figure 6C As shown, the carrier bandwidth 602 (or active BWP) can be divided into subbands 610a and 610b. Each subband 610a and 610b can be allocated for communication in a single direction. For example, subband 610a can be allocated for downlink transmission, while subband 610b can be allocated for uplink transmission. Therefore, the downlink resource 606 allocated for transmission in the downlink direction overlaps with the uplink resource 608 allocated for transmission in the uplink direction in time, but not in frequency. The downlink resource 606 can also be separated from the uplink resource 608 in the frequency domain by a guard band 612 to isolate uplink and downlink transmissions in frequency.

[0096] Figure 7A This is a schematic diagram of a base station 702 (e.g., a gNB) configured for full-duplex communication, including a multi-panel antenna array 700, according to some aspects of this disclosure. The antenna array 700 is divided into two panels (panel 1 704, panel 2 706) with a physical spacing 708 between them. Each of the two panels can be an antenna subarray. A given panel can transmit and / or receive beams or beam groups. In one example, the panels may be physically separated from each other by a distance chosen to provide improved isolation between simultaneous transmit (Tx) and receive (Rx) operations in full-duplex mode, thereby mitigating at least a portion of self-interference caused by simultaneously transmitted / received signals. Figure 7AThe multi-panel antenna configuration shown can also be applied to the UE to enable full-duplex communication at the UE (e.g., SBFD).

[0097] Figure 7B It is based on the use in some aspects Figure 7A This is a schematic diagram illustrating an example of sub-band full-duplex wireless communication 710 of the multi-panel antenna array 700 shown. Figure 7B In the example shown, time is in the horizontal direction, in units of time slots 712a-712d, each time slot including multiple OFDM symbols; and frequency is in the vertical direction. Here, carrier bandwidth 714 (or a set of one or more active BWPs) is shown along the frequency axis. Carrier bandwidth 714 (or active BWPs) can be divided into a number of subbands 750a-750c for subband FD operation.

[0098] exist Figure 7B In the example shown, in time slot 712a, antenna array 700 is initially configured for downlink (DL) communication (e.g., DL burst 716 and DL data portion 718). DL burst 716 may include DL control transmitted within the first few symbols of time slot 712a. DL control may include, for example, a Physical Downlink Control Channel (PDCCH) carrying a DCI, which may be associated with time slot 712a or previous or subsequent time slots. In one example, the DCI may include a common DCI or a UE-specific DCI. A common DCI may include, for example, common control information broadcast to a group of UEs or all UEs in the cell. A UE-specific DCI may include, for example, HARQ feedback information (e.g., ACK / NACK), scheduling information for scheduling downlink data transmission and / or uplink transmission in time slot 712a or subsequent time slots (e.g., time slots 712b, 712c, and / or 712d), and other appropriate information. DL burst 716 may also include various DL reference signals (e.g., SSB and / or CSI-RS). In this example, both panel 1 704 and panel 2 706 can be configured for DL ​​transmission. The DL data section 718 may include DL data carried, for example, within a PDSCH. In addition to the DL data, the DL data section 718 may also include a DL reference signal (e.g., DMRS) used during demodulation and decoding of the DL data.

[0099] Time slot 712a may also include a common uplink (UL) burst 722 at the end of time slot 712a. The common UL burst 722 may include, for example, a PUCCH carrying UCI and other UL signals. Figure 7BAs shown, the end of the DL data portion 718 can be separated in time from the start of the UL burst 722. This time separation 720 may sometimes be referred to as a gap, guard period, guard interval, and / or various other appropriate terms. This separation provides time for the base station and UE to perform transitions between transmission and reception, or vice versa. In this example, both panel 1 704 and panel 2 706 can be configured for UL transmission during the UL burst 722.

[0100] In time slots 712b and 712c, antenna array 700 is configured for both DL and UL communication. For example, in time slots 712b and 712c, carrier bandwidth 714 (or active BWP) is shown as being divided between uplink and downlink transmissions. Subbands 750a and 750b are allocated for downlink transmission, while subband 750c is allocated for uplink transmission. Figure 7A In the example operation of the subband full-duplex configuration shown, panel 1 704 can be configured to perform DL transmission at both edges of the carrier bandwidth 714 (or active BWP), e.g., subbands 750a and 750b, and panel 2 706 can be configured to perform UL reception at the middle of the carrier bandwidth 714 (or active BWP), e.g., subband 750c.

[0101] In each of the subband FD time slots 712b and 712c, the DL subbands 750a and 750b respectively include DL bursts 724 and 734, which may include a PDCCH carrying DCI and / or DL ​​reference signals in the initial or beginning portion of time slots 712b and 712c. Following DL bursts 724 and 734, time slots 712b and 712c each include DL data portions 726 and 736, respectively, for transmitting DL data within subbands 750a and 750b. For example, DL data may be transmitted within a PDSCH. In addition to DL data, DL data portions 726 and 736 may also include DL reference signals (e.g., DMRS) for use in demodulating and decoding the DL data.

[0102] In the uplink (UL) subband 750c, timeslots 712b and 712c each include UL data portions 728 and 738 for transmitting UL data, respectively. For example, the UL data may be transmitted within a PUSCH. Following the UL data portions 728 and 738, the UL subbands 750c of timeslots 712b and 712c each include UL bursts 730 and 740, respectively. UL bursts 730 and 740 may include, for example, a PUCCH, which includes UCI and / or other UL signals. A guard band 732 is also provided between the UL subband 750c and the DL subbands 750a and 750b to mitigate self-interference between simultaneous DL transmissions in the DL subbands 750a and 750b and UL transmissions in the UL subband 750c.

[0103] Time slots 712b and 712c are sub-band FD time slots that utilize FDM for frequency multiplexing of uplink and downlink transmissions. Figure 7B The sub-band full-duplex time slot configuration shown is merely exemplary, and other configurations of sub-band full-duplex time slots can be utilized in various aspects of this disclosure. For example, other configurations including UL and DL sub-bands can be employed in various aspects (e.g., in...). Figure 4C The subband full-duplex time slots (as shown in the configuration or other suitable subband configurations).

[0104] In time slot 712d, antenna array 700 is configured for UL communication. For example, time slot 712d includes a UL data portion 742, followed by a UL burst 744. As discussed above, UL data portion 742 and UL burst 744 may include UL control information and / or UL data. In this example, both panel 1 704 and panel 2 706 can be configured for UL reception. Time slots 712a and 712d are half-duplex TDD time slots utilizing TDM for time multiplexing of DL and UL transmissions.

[0105] In some aspects of this disclosure, one or more time slots may be flexible time slots comprising one or more flexible symbols, which may be configured as half-duplex symbols (e.g., all UL or all DL) or subband full-duplex symbols (e.g., including both UL and DL transmissions). For example, in time slot 712b, DL burst 724 may be configured to occupy all subbands 750a-750c of time slot 712b, and accordingly, the symbol corresponding to DL burst 724 may be a flexible symbol, which may be configured as a half-duplex symbol to enable DL communication across all subbands 750a-750c. Similarly, UL burst 730 may be configured to occupy all subbands 750a-750c of time slot 712b, and accordingly, the symbol corresponding to UL burst 730 may be a flexible symbol, which may be configured as a half-duplex symbol to enable UL communication across all subbands 750a-750c.

[0106] In subband full-duplex operation, the time slot format can be classified according to the base station's duplex mode. For example, time slots can be classified as half-duplex time slots (e.g., time slots 712a or 712b) that include symbols dedicated to TDM-based DL or UL transmissions. Furthermore, time slots can be classified as hybrid full-duplex (or subband full-duplex) time slots (e.g., time slots 712b or 712c) that include both FDM-based DL and UL transmissions. Time slots can also be classified as flexible time slots that are partially or fully configurable (e.g., one or more symbols can be flexible symbols).

[0107] In various aspects of this disclosure, to accommodate low-latency and / or high-reliability services (such as Ultra-Reliable Low-Latency Communication (URLLC)), base stations operating in sub-band full-duplex mode can dynamically change the time slot format between half-duplex and sub-band full-duplex, and / or can change the flexible symbols within flexible time slots between half-duplex and sub-band full-duplex. A time slot format indicator (SFI) indicating the time slot format can be signaled, for example, via a DCI mapped to the PDCCH or a Media Access Control (MAC) control element (MAC-CE) mapped to the PDSCH.

[0108] Figure 8 This is a table depicting, based on some aspects of this disclosure, a four-tuple 800 of a slot format organized by the SlotFormatCombinationID number 802 specified by the SlotFormatIndicator (SFI) 804 in the downlink control information (DCI) payload 806. Figure 8In the example, the format of time slot 808 includes time slot format 0 810, time slot format 42 812, time slot format 1 814, time slot format 32 816, and time slot format 56 818. The DCI payload 806 can, for example, be in the form of a DCI format 2_0 message. Figure 8 In the example, the DCI payload includes seven SFIs. Figure 8 In one example, the scheduling entity (e.g., gNB) has used the SFI5 of the DCI payload to communicate the slot format combination to the scheduled entity. The scheduled entity can extract the SFI5 from the DCI payload. In this example, from Figure 8 In the slot format tuple 800, SFI5 can point to SlotFormatCombinationID3 802. SlotFormatCombinationID3 802 corresponds to slot format 0 810 (representing a slot formatted with all DL symbols), slot format 56 818 (representing a slot formatted with a combination of DL, UL, and flexible (F) symbols), and slot format 1 814 (representing a slot formatted with all UL symbols).

[0109] Figure 8 The time slot format may not be prepared for situations where the scheduling entity attempts to format the time slots with at least one downlink-uplink (DU) symbol. At least one DU symbol may be a symbol reserved for simultaneous downlink and uplink transmissions (and their respective receptions) in the same carrier bandwidth (e.g., in the same frequency band).

[0110] As described above, in addition to DL, UL, and F symbols, the scheduling entity can configure time slots for SBFD (or more generally, full-duplex) operation, which have at least one downlink-uplink (DU) symbol reserved for both downlink and uplink transmissions occurring simultaneously in the same carrier bandwidth (e.g., within the same frequency band). The DU symbol can be different from the downlink (DL) symbol, uplink (UL) symbol, and flexible (F) symbol. For example, the DL symbol and UL symbol are reserved for DL ​​transmission and UL reception, respectively. DL transmission and UL transmission are examples of unidirectional communication. DL transmission and UL transmission (e.g., reception of UL transmission) can occur simultaneously at different frequencies (as in the case of FDD FD), or at the same frequency at different times (as in the case of TDD HD), but not simultaneously in the same frequency band (as in the case of SBFD). The F symbol is interpreted as either a UL symbol or a DL symbol, and thus has the same characteristics as a DL symbol or a UL symbol. The F symbol does not combine the characteristics of UL symbols and DL symbols. As used in this article, the term "symbol type" can be used to identify the symbol types D, U, F, and / or DU.

[0111] Scheduling entities capable of SBFD operations may be unaware of the capabilities of the scheduled entities they serve, and may attempt to configure time slots for SBFD (or full-duplex) operations using one or more DU symbols. However, as described above, the behavior of non-SBFD scheduled entities may be undefined. Defining the behavior of non-SBFD UEs when encountering DU symbols allows non-SBFD UEs to continue operating in wireless network environments where SBFD transceivers are first used, and prepares for the continued presence and future use of low-cost non-SBFD UEs in SBFD environments.

[0112] Figure 9 This is a schematic diagram depicting a tuple 900 of exemplary and non-limiting time slot formats, wherein each of the three exemplary time slot formats depicted includes at least one DU symbol according to some aspect of this disclosure. According to some existing specifications, there are multiple reserved SFIs. At least some of these reserved SFIs can be used to describe a time slot format including at least one DU symbol. For example, in 5G, SFIs 56 to 254 are reserved and currently undefined. Therefore, the aspects described herein can utilize SFIs including, for example, time slot formats describing a complete set of DU symbols (e.g., 14 DU symbols) and SFIs including, for example, mixed sets of DU, DL, UL, and F symbols (e.g., where the mixed set includes at least one DU symbol plus some combination of DL, UL, and / or F symbols). Figure 9 Three exemplary time slot formats are given.

[0113] In some examples, a non-SBFD scheduled entity (e.g., a UE or other wireless communication device) can be a scheduled entity with only half-duplex capability but aware of a full-duplex time slot including at least one DU symbol. An FD-aware non-SBFD scheduled entity can be configured with a DU time slot (i.e., a time slot including at least one DU symbol), wherein the FD-aware non-SBFD scheduled entity is able to interpret the frequency domain information associated with the DU time slot. The FD-aware non-SBFD scheduled entity can operate, for example, in UL mode or DL ​​mode during the DU time slot.

[0114] A first exemplary time slot format 902 (e.g., time slot format X) includes 14 symbols. All 14 symbols of the first exemplary time slot format 902 are DU symbols. A second exemplary time slot format 904 (e.g., time slot format Y) includes 14 symbols. The first 11 symbols of the second exemplary time slot format 904 are DU symbols, the 12th symbol is an F symbol, and the last two symbols are UL symbols. A third exemplary time slot format 906 (e.g., time slot format Z) includes 14 symbols. The first 11 symbols of the third exemplary time slot format 906 are DU symbols, the 12th symbol is an F symbol, and the last two symbols are DL symbols. The exemplary time slot formats are three combinations of many possible combinations of DU plus F, DL, and / or UL symbols. Having a combination with those for... Figure 9 The 14 symbols shown in each of the three exemplary time slot formats are compared to time slot formats with fewer or more symbols within the scope of this disclosure.

[0115] However, problems may arise when a scheduling entity formats time slots to have at least one DU symbol, and when a scheduled entity attempting to comply with the time slot format proposed by the scheduling entity is not configured for full-duplex operation (e.g., a non-SBFD scheduled entity). Examples of such non-SBFD scheduled entities could be scheduled entities configured for half-duplex (HD) operation and scheduled entities configured for full-duplex sensing (FD-aware) operation. These non-SBFD scheduled entities may exhibit undefined behavior in cases where the time slot format includes a time slot configuration containing at least one DU symbol (sometimes referred to herein as a DU time slot configuration). Therefore, aspects of this disclosure can prepare for DU time slot interpretation that can be used by non-SBFD scheduled entities operating in a wireless communication network utilizing a time slot format including at least one DU symbol. For example, aspects of this disclosure can inform the behavior of non-SBFD scheduled entities encountering a time slot format including at least one DU symbol during operation in a wireless communication network.

[0116] Figure 10This is a block diagram illustrating an example of a hardware implementation of a scheduling entity 1000 in a processing system 1002 according to some aspects of this disclosure. The scheduling entity 1000 can be, for example, as shown in... Figure 1 , Figure 2 Figure 4 and / or Figure 7A Any one or more of the base stations, eNBs, gNBs, or network access nodes shown in the diagram.

[0117] According to various aspects of this disclosure, any element, any part of an element, or any combination of elements can be implemented using a processing system 1002 including one or more processors, such as processor 1004. Examples of processor 1004 include microprocessors, microcontrollers, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuitry, and other suitable hardware configured to perform the various functions described throughout this disclosure. In various examples, scheduling entity 1000 can be configured to perform any one or more of the functions described herein. That is, processor 1004, as utilized in scheduling entity 1000, can be used to implement, for example, in Figure 11 , Figure 12 , Figure 14 and / or Figure 15 Any one or more of the methods or processes described and shown in the document.

[0118] Processor 1004 may be implemented via a baseband or modem chip in some cases, while in other implementations, processor 1004 may include a number of devices that are distinct from and different from the baseband or modem chip (e.g., in scenarios where they can work together to implement the examples discussed herein). Furthermore, as mentioned above, various hardware arrangements and components other than the baseband modem processor may be used in the various implementations, including RF chains, power amplifiers, modulators, buffers, interleavers, adders / summers, etc.

[0119] In this example, processing system 1002 can be implemented using a bus architecture, typically represented by bus 1006. Depending on the specific application and overall design constraints of processing system 1002, bus 1006 can include any number of interconnect buses and bridges. Bus 1006 communicatively couples together various circuits including one or more processors (typically represented by processor 1004), memory 1008, and computer-readable media (typically represented by computer-readable media 1010). Bus 1006 can also link various other circuits such as timing sources, peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further.

[0120] Bus interface 1012 provides an interface between bus 1006 and transceiver 1014. Transceiver 1014 may be a wireless transceiver. Transceiver 1014 can provide a unit for communicating with various other devices via a transmission medium (e.g., an air interface). Transceiver 1014 may also be coupled to one or more antennas / antenna arrays / antenna modules (hereinafter referred to as antenna 1016). In some examples, transceiver 1014 and antenna 1016 may be configured to transmit and receive using directional beamforming (e.g., using a single beam or beam-to-beam link (BPL) on each of the uplink and downlink transmissions). Bus interface 1012 also provides an interface between bus 1006 and user interface 1018 (e.g., keypad, display, touchscreen, speaker, microphone, control features, etc.). Of course, such user interface 1018 is optional and may be omitted in some examples. In addition, bus interface 1012 also provides an interface between bus 1006 and power supply 1020 of scheduling entity 1000.

[0121] Processor 1004 is responsible for managing bus 1006 and general processing, including the execution of software stored on computer-readable medium 1010. When executed by processor 1004, the software causes processing system 1002 to perform the various functions described below for any particular device. Computer-readable medium 1010 and memory 1008 may also be used to store data manipulated by processor 1004 during software execution.

[0122] Whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise, software should be broadly interpreted to mean instructions, instruction sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc. Software may reside on computer-readable medium 1010. When executed by processor 1004, software can cause processing system 1002 to perform the various processes and functions described herein for any particular device.

[0123] Computer-readable medium 1010 can be a non-transitory computer-readable medium, and can be referred to as a computer-readable storage medium or a non-transitory computer-readable medium. A non-transitory computer-readable medium can store computer-executable code (e.g., processor-executable code). Computer-executable code can include code for causing a computer (e.g., a processor) to perform one or more of the functions described herein. For example, non-transitory computer-readable media include magnetic storage devices (e.g., hard disks, floppy disks, magnetic tapes), optical disks (e.g., compact discs (CDs) or digital versatile discs (DVDs)), smart cards, flash memory devices (e.g., card, stick, or key drives), random access memory (RAM), read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), registers, removable disks, and any other suitable medium for storing software and / or instructions that can be accessed and read by a computer. Computer-readable medium 1010 can be present in, outside of, or distributed across multiple entities including processing system 1002. Computer-readable medium 1010 may be embodied in a computer program product or article of manufacture. For example, a computer program product or article of manufacture may include a computer-readable medium contained in packaging material. In some examples, computer-readable medium 1010 may be part of memory 1008. Those skilled in the art will recognize how the functions described herein are best implemented, depending on the specific application and the overall design constraints imposed on the system as a whole.

[0124] In some aspects of this disclosure, processor 1004 may include communication and processing circuitry 1041 configured for various functions, including, for example, communicating with a scheduled entity (e.g., a UE or other wireless communication device), a network core (e.g., a 5G core network), other scheduling entities, or any other entity (such as, for example, local infrastructure, or an entity communicating with scheduling entity 1000 via the Internet, such as a network provider)). In some examples, communication and processing circuitry 1041 may include one or more hardware components that provide the physical structure for performing processes related to wireless communication (e.g., signal reception and / or signal transmission) and signal processing (e.g., processing received signals and / or processing signals for transmission). For example, communication and processing circuitry 1041 may include one or more transmit / receive chains.

[0125] In some implementations of communication involving the reception of information, communication and processing circuitry 1041 may obtain information from components of scheduling entity 1000 (e.g., transceiver 1014 that receives information via radio frequency signaling or other types of signaling suitable for applicable communication media), process (e.g., decode) the information, and output the processed information. For example, communication and processing circuitry 1041 may output information to another component of processor 1004, to memory 1008, or to bus interface 1012. In some examples, communication and processing circuitry 1041 may receive one or more of the following: signals, messages, other information, or any combination thereof. In some examples, communication and processing circuitry 1041 may receive information via one or more channels. In some examples, communication and processing circuitry 1041 may include functionality for units used for receiving. In some examples, communication and processing circuitry 1041 may include functionality for units used for processing, including units for demodulation, units for decoding, etc.

[0126] In some implementations of communication involving the transmission (e.g., sending) of information, communication and processing circuitry 1041 may (e.g., from another component of processor 1004, memory 1008, or bus interface 1012) obtain information, process (e.g., modulate, encode, etc.) the information, and output the processed information. For example, communication and processing circuitry 1041 may output information to transceiver 1014 (e.g., which transmits information via radio frequency signaling or other types of signaling suitable for applicable communication media). In some examples, communication and processing circuitry 1041 may transmit one or more of signals, messages, other information, or any combination thereof. In some examples, communication and processing circuitry 1041 may transmit information via one or more channels. In some examples, communication and processing circuitry 1041 may include functionality for units used for transmission (e.g., units for sending). In some examples, communication and processing circuitry 1041 may include functionality for units used for generation, including units for modulation, units for encoding, etc.

[0127] The communication and processing circuit 1041 can also be configured to send a DU timeslot interpretation or a value representing the DU timeslot interpretation to the scheduled entity, which the scheduled entity can use to interpret the DU timeslot. For example, a first value indicating the selected HD DU timeslot interpretation (if the duplex mode of the scheduled entity is HD) or a second value indicating the selected FD-aware DU timeslot interpretation (if the duplex mode of the scheduled entity is FD-aware) can be performed by the communication and processing circuit 1041. The transmission can be accomplished, for example, via RRC signaling. Other methods of sending the first and second values ​​are within the scope of this disclosure. Furthermore, the communication and processing circuit 1041 can be configured to receive and process uplink traffic and uplink control messages (e.g., similar to) via antenna 1016 and transceiver 1014. Figure 1 The communication and processing circuitry 1041 can also be configured to execute communication and processing software 1051 stored on a computer-readable medium 1010 to perform one or more of the functions described herein. This includes processing and transmitting uplink service 116 and uplink control 118, as well as downlink service and downlink control messages (e.g., similar to downlink service 112 and downlink control 114).

[0128] In some aspects of this disclosure, processor 1004 may include duplex mode acquisition circuitry 1042 configured for various functions, including, for example, acquiring the duplex mode of a scheduled entity (e.g., a UE or other wireless communication device) that is wirelessly communicating with a scheduling entity. In some examples, various duplex modes may include half-duplex (HD), full-duplex (FD), and full-duplex awareness (FD awareness); however, examples of duplex modes include, but are not limited to, HD, FD (FD awareness), frequency division duplex (FDD), time division duplex (TDD), sub-band full-duplex (SBFD) (also referred to as flexible duplex), in-band full-duplex (IBFD), and space division duplex (SDD). Duplex mode acquisition circuitry 1042 may also determine whether the scheduled entity is pre-configured to interpret DU time slots (e.g., time slots formatted to have at least one DU symbol). The duplex mode and / or whether the scheduled entity is pre-configured to interpret DU time slots can be obtained, for example, from the scheduled entity via signaling (e.g., RRC signaling) and / or from a centralized function or server (such as a Unified Data Management (UDM) function or a Home Subscriber Server (HSS)). The foregoing list is exemplary and non-limiting. Other ways for the scheduling entity to obtain the duplex mode of the scheduled entity and / or determine whether the scheduled entity is pre-configured to interpret DU time slots are within the scope of this disclosure. In some examples, the duplex mode acquisition circuit 1042 may include one or more hardware components that provide a physical structure that performs processes related to obtaining the duplex mode of the scheduled entity and / or determining whether the scheduled entity is pre-configured to interpret DU time slots. The duplex mode acquisition circuit 1042 may also be configured to execute duplex mode acquisition software 1052 stored on a computer-readable medium 1010 to implement one or more of the functions described herein.

[0129] In some aspects of this disclosure, processor 1004 may include DU time slot interpretation selection circuitry 1043, configured for various functions, including, for example, selecting, based on the duplex mode of the scheduled entity, the DU time slot interpretation to be applied by the scheduled entity to time slots including downlink-uplink (DU) symbols, wherein DU symbols may be reserved for simultaneous downlink and uplink transmissions in the same carrier bandwidth (e.g., in the same frequency band). DU time slot interpretation selection circuitry 1043 may include HD DU and / or FD-aware DU time slot interpretation selection aspects. In some examples, DU time slot interpretation selection circuitry 1043 may include one or more hardware components providing a physical structure that performs the process related to the selection of DU time slot interpretation to be applied by the scheduled entity to time slots including DU symbols based on the duplex mode of the scheduled entity. DU time slot interpretation selection circuitry 1043 may also be configured to execute DU time slot interpretation selection software 1053 stored on computer-readable medium 1010 to implement one or more of the functions described herein.

[0130] Figure 11 This is a flowchart illustrating an exemplary process 1100 (e.g., a wireless communication method) at a scheduling entity in a wireless communication network according to some aspects of this disclosure. The scheduling entity (e.g., a network access node, base station, gNB) can be configured with time slots having at least one downlink-uplink (DU) symbol reserved for downlink and uplink transmissions. The DU symbol can be configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). According to some aspects, the DU symbol can be reserved for simultaneous downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). As described below, some or all of the features shown may be omitted in specific implementations within the scope of this disclosure, and some of the shown features may not be required for all example implementations. In some examples, process 1100 may be performed by... Figure 10 The scheduling entity 1000 shown is used to execute this process. In some examples, process 1100 may be executed by any suitable means or unit for performing the functions or algorithms described herein.

[0131] At box 1102, the scheduling entity can obtain the duplex mode of the scheduled entity (e.g., UE or other wireless communication device). In some examples, the obtained duplex mode can be half-duplex (HD), full-duplex (FD), or full-duplex aware (FD aware); however, the obtained duplex mode is not limited to HD, FD, and FD aware. For example, examples of duplex modes can include, but are not limited to, HD, FD, (FD aware), frequency division duplex (FDD), time division duplex (TDD), sub-band full-duplex (SBFD) (also known as flexible duplex), in-band full-duplex (IBFD), and space division duplex (SDD). For example, the above combined with Figure 10 The communication and processing circuitry 1041, duplex mode acquisition circuitry 1042, and / or transceiver 1014 and antenna 1016 shown and described may provide units for acquiring the duplex mode of the scheduled entity.

[0132] At box 1104, the scheduling entity can select, based on the duplex mode of the scheduled entity, the DU slot interpretation to be applied by the scheduled entity to slots including downlink-uplink (DU) symbols. DU symbols can be configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). In some aspects, DU symbols can be different from downlink (DL) symbols, uplink (UL) symbols, and flexible (F) symbols. According to some aspects, the scheduling entity can also send downlink control information (DCI) to the scheduled entity, where the DCI can include slot information for slots including DU symbols (or, according to some aspects, where the DCI can indicate slots including DU symbols). For example, the slot information can include at least one of the following: slot format indication (SFI), slot format combination identifier (SlotFormatCombinationID), slot format number or ID, symbol type, or symbol location. In one example, uplink and downlink transmissions can partially or completely overlap within the carrier bandwidth (e.g., within the frequency band) of the DU symbol. In another example, the uplink and downlink can occur simultaneously at different non-overlapping frequencies within the DU symbol. In some examples, DL and UL symbols are reserved for DL ​​and UL respectively when: at the same first time at different respective first frequencies in paired spectra, or at different respective second times at the same second frequency; and the F symbol can be interpreted as either a UL symbol or a DL symbol. In some examples, the DU symbol is reserved for DL ​​and UL when: at the same third time at different respective third frequencies in unpaired spectra (e.g., Figure 5D Reference number 530; or Figure 6B (Ref. 602), or for example, at the same fourth time at the same fourth frequency in the unpaired spectrum (e.g., Figure 6A (Ref. 614). According to some aspects, different respective first frequencies in paired spectra may have a first guard band between them, different respective third frequencies in unpaired spectra may have a second guard band between them, and the second guard band may be smaller than the first guard band.

[0133] According to one example, if the duplex mode of the scheduled entity is half-duplex (HD), then at box 1104, selecting the DU slot interpretation may further include selecting at least one of the following: a first DU slot interpretation that causes the scheduled entity to treat a first slot format indicator (SFI) (or, depending on some aspects, a first slot format indicator (SFI) indicating a slot including a DU symbol) as an error; a second DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot including a DU symbol as a flexible (F) symbol; and a third DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot including a DU symbol as a downlink (DL) symbol. The fourth DU time slot interpretation causes the scheduled entity to perform at least one of the following: treat all DU symbols in a time slot containing a DU symbol, followed by one or more DL symbols, as DL symbols; treat all F symbols in a time slot containing a DU symbol, followed by one or more DL symbols, as DL symbols; treat all UL symbols in a time slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or treat all F symbols in a time slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or the fifth DU time slot interpretation causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. According to some aspects, the reserved SFI may indicate a time slot formatted to have all DL symbols or all UL symbols.

[0134] According to another example, if the duplex mode of the scheduled entity is full-duplex aware (FD aware), where the scheduled entity is aware of full-duplex time slots including DU symbols, then at box 1104, selecting the DU time slot interpretation may further include selecting at least one of the following: a first DU time slot interpretation, which causes the scheduled entity to treat all symbols in the time slots including DU symbols as DL symbols or UL symbols according to parameters pre-configured in the scheduled entity; a second DU time slot interpretation, which causes the scheduled entity to treat all symbols in the time slots including DU symbols according to RRC parameters; and a third DU time slot interpretation, which causes the scheduled entity to treat all symbols in the time slots including DU symbols as flexible (F) symbols, where the Physical Downlink Control Channel (PDCCH) determines that an F symbol is treated as an uplink (UL) symbol. The first SFI is either a DU symbol or a downlink (DL) symbol; the fourth DU slot interpretation causes the scheduled entity to perform at least one of the following: treat all DU symbols in a slot containing a DU symbol, followed by one or more DL symbols, as DL symbols; treat all F symbols in a slot containing a DU symbol, followed by one or more DL symbols, and one or more DU symbols as DL symbols; treat all UL symbols in a slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or treat all F symbols in a slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or the fifth DU slot interpretation causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. According to some aspects, the reserved SFI may indicate a slot formatted to have all DL symbols or all UL symbols.

[0135] For example, the above text combined Figure 10 The DU slot interpretation selection circuit 1043 shown and described can provide a unit for selecting the DU slot interpretation to be applied by the scheduled entity to slots including downlink-uplink (DU) symbols based on the duplex mode of the scheduled entity.

[0136] At box 1106, the scheduling entity can send a DU slot explanation to the scheduled entity. For example, in conjunction with the above... Figure 10 The communication and processing circuitry 1041 and / or transceiver 1014 and antenna 1016 shown and described may provide units for transmitting DU time slot interpretations to the scheduled entity.

[0137] Figure 12This is a flowchart illustrating another exemplary process 1200 (e.g., a wireless communication method) at a scheduling entity in a wireless communication network according to some aspects of this disclosure. The scheduling entity (e.g., a network access node, base station, gNB) can be configured with time slots having at least one downlink-uplink (DU) symbol reserved for downlink and uplink transmissions. The DU symbol can be configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). According to some aspects, the DU symbol can be reserved for simultaneous downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). As described below, some or all of the features shown may be omitted in specific implementations within the scope of this disclosure, and some of the shown features may not be required for all example implementations. In some examples, process 1200 may be performed by... Figure 10 The scheduling entity 1000 shown is responsible for execution. In some examples, process 1200 may be executed by any suitable means or unit for performing the functions or algorithms described herein.

[0138] At box 1202, the scheduling entity can obtain the duplex mode of the scheduled entity (e.g., UE or other wireless communication device). In some examples, the obtained duplex mode can be half-duplex (HD), full-duplex (FD), or full-duplex aware (FD aware); however, the obtained duplex mode is not limited to HD, FD, and FD aware. For example, examples of duplex modes can include, but are not limited to, HD, FD, (FD aware), frequency division duplex (FDD), time division duplex (TDD), sub-band full-duplex (SBFD) (also known as flexible duplex), in-band full-duplex (IBFD), and space division duplex (SDD). For example, the above combined with Figure 10 The communication and processing circuitry 1041, duplex mode acquisition circuitry 1042, and / or transceiver 1014 and antenna 1016 shown and described may provide units for acquiring the duplex mode of the scheduled entity.

[0139] At box 1204, the scheduling entity can determine whether the obtained duplex mode is full-duplex. If the obtained duplex mode is full-duplex, the scheduled entity may have already been configured to communicate using at least one DU symbol, and the process can end. However, if at box 1204, the scheduling entity determines that the obtained duplex mode of the scheduled entity is not full-duplex, the scheduling entity can proceed to box 1206. For example, in conjunction with the above... Figure 10 The communication and processing circuitry 1041 shown and described may provide a unit for determining whether the obtained duplex mode is full-duplex.

[0140] At box 1206, the scheduling entity can determine whether the duplex mode of the acquired scheduled entity is half-duplex (HD). If the acquired duplex mode is HD, then at box 1208, the scheduling entity can determine whether the scheduled entity is pre-configured to interpret DU symbols in a timeslot format. If the scheduling entity determines that the scheduled entity is pre-configured to interpret DU symbols in a timeslot format, the process can end. However, at box 1208, if the scheduling entity determines that the scheduled entity is not pre-configured to interpret at least one DU symbol, the scheduling entity can proceed to box 1210. For example, the above combined with... Figure 10 The communication and processing circuitry 1041 shown and described may provide units for determining whether the obtained duplex mode is HD and whether the scheduled entity is pre-configured to interpret DU symbols in a time slot format.

[0141] At box 1210, the scheduling entity can select an HDDU slot interpretation from multiple differentiated HDDU slot interpretations, each of which determines how the scheduled entity can interpret at least one DU symbol. For example, in conjunction with the above... Figure 10 The DU timeslot interpretation selection circuit 1043 (including HDDU and / or FD-aware DU timeslot interpretations) shown and described can provide elements for determining how a scheduling entity selects an HDDU timeslot interpretation from a plurality of differentiated HDDU and / or FD-aware DU timeslot interpretations. Thereafter, at block 1212, the scheduling entity can send a first value indicating the selected HDDU timeslot interpretation to the scheduled entity via Radio Resource Control (RRC) signaling. For example, in conjunction with the above... Figure 10 The communication and processing circuitry 1041 and / or transceiver 1014 and antenna 1016 shown and described may provide units for transmitting a first value indicating the interpretation of the selected HDDU timeslot to the scheduled entity. The process can then terminate.

[0142] Returning to box 1206, if the scheduling entity determines that the duplex mode of the acquired scheduled entity is not HD, the process can proceed to box 1214. At box 1214, the scheduling entity can determine whether the acquired duplex mode is FD-aware. If the acquired duplex mode is FD-aware, then at box 1216, the scheduling entity can determine whether the scheduled entity is pre-configured to interpret DU symbols in a slotted format. If the scheduled entity is pre-configured to interpret DU symbols in a slotted format, the process can end. However, at box 1216, if the scheduling entity determines that the scheduled entity is not pre-configured to interpret at least one DU symbol, the scheduling entity can proceed to box 1218. For example, the above combined... Figure 10The communication and processing circuitry 1041 shown and described may provide units for determining whether the duplex mode of the obtained scheduled entity is not HD and whether the obtained duplex mode is FD-aware, and may provide units for determining whether the scheduled entity is pre-configured to interpret DU symbols in a time slot format.

[0143] At box 1218, the scheduling entity can select an FD-aware DU slot interpretation from multiple differentiated FD-aware DU slot interpretations. Each of these differentiated FD-aware DU slot interpretations determines how the scheduled entity can interpret at least one DU symbol. For example, in conjunction with the above... Figure 10 The DU timeslot interpretation selection circuit 1043 (including HDDU and / or FD-aware DU timeslot interpretations) shown and described can provide a unit for determining how a scheduling entity selects an FD-aware DU timeslot interpretation from a plurality of differentiated HDDU and / or FD-aware DU timeslot interpretations. Thereafter, at block 1220, the scheduling entity can send a second value indicating the selected FD-aware DU timeslot interpretation to the scheduled entity via Radio Resource Control (RRC) signaling. For example, in conjunction with the above... Figure 10 The communication and processing circuitry 1041 and / or transceiver 1014 and antenna 1016 shown and described may provide units for transmitting a second value indicating the interpretation of the selected FD-aware DU time slot to the scheduled entity. The process can then terminate.

[0144] According to some aspects, the process may also include sending downlink control information (DCI) to the scheduled entity, the DCI including time slot information for time slots comprising at least one DU symbol (or, according to some aspects, the DCI indicating time slots comprising at least one DU symbol). For example, the above combined with Figure 10 The communication and processing circuitry 1041 and / or transceiver 1014 and antenna 1016 shown and described may provide units for transmitting downlink control information (DCI) to the scheduled entity.

[0145] According to some aspects, at least one DU symbol may be different from an uplink (UL) symbol, a downlink (DL) symbol, and a flexible (F) symbol, because DL symbols and UL symbols are reserved DL and UL transmissions that are performed simultaneously at different frequencies or at different times at the same frequency, and an F symbol can be interpreted as either a UL symbol or a DL symbol.

[0146] According to some examples, selecting an HDDU slot interpretation from multiple differentiated HDDU slot interpretations includes selecting at least one of the following: an HD first DU slot interpretation that causes the scheduled entity to treat a first slot format indicator (SFI) including slot information for a slot including at least one DU symbol as an error (or, according to some aspects, to treat a first slot format indicator (SFI) indicating a slot including at least one DU symbol as an error); an HD second DU slot interpretation that causes the scheduled entity to treat each DU symbol included in a slot formatted according to the first SFI as a flexible (F) symbol; or an HD third DU slot interpretation that causes the scheduled entity to treat each DU symbol included in a slot formatted according to the first SFI as a downlink (DL) symbol. According to other examples, selecting an HDDU time slot interpretation from multiple distinct HDDU time slot interpretations may also include selecting an HD fourth DU time slot interpretation, which causes the scheduled entity to perform at least one of the following: treating all DU symbols in a time slot formatted according to the first SFI, followed by one or more DL symbols, as DL symbols; treating all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DL symbols, as DL symbols; treating all UL symbols in a time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or treating all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or an HD fifth DU time slot interpretation, which causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. According to some aspects, the reserved SFI may indicate a time slot formatted to have all DL symbols or all UL symbols.

[0147] According to other examples, selecting an FD-aware DU time slot interpretation from multiple differentiated FD-aware DU time slot interpretations may include selecting at least one of the following: an FD-aware first DU time slot interpretation, which causes the scheduled entity to treat all symbols in a time slot associated with a first time slot format indicator (SFI) (or, according to some aspects, a first time slot format indicator (SFI) indicating a time slot including at least one DU symbol) as DL symbols or UL symbols, based on parameters pre-configured in the scheduled entity; an FD-aware second DU time slot interpretation, which causes the scheduled entity to treat all symbols in a time slot associated with the first SFI according to RRC parameters; or an FD-aware third DU time slot interpretation, which causes the scheduled entity to treat each DU symbol included in a time slot formatted according to the first SFI as a flexible (F) symbol, wherein the physical downlink control channel (PDCCH) determines whether an F symbol is treated as an uplink (UL) symbol or a downlink (DL) symbol. Alternatively, selecting an FD-aware DU time slot interpretation from a plurality of distinct FD-aware DU time slot interpretations may also include selecting at least one of the following: an FD-aware fourth DU time slot interpretation, which causes the scheduled entity to perform at least one of the following: treating all DU symbols in a time slot formatted according to the first SFI, followed by one or more DL symbols, as DL symbols; treating all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DL symbols, as DL symbols; treating all UL symbols in a time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or treating all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or an FD-aware fifth DU time slot interpretation, which causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. According to some aspects, the reserved SFI may indicate a time slot formatted to have all DL symbols or all UL symbols.

[0148] In one example, a scheduling entity for wireless communication may include: a unit for obtaining the duplex mode of a scheduled entity that is wirelessly communicating with the scheduling entity; a unit for selecting, based on the duplex mode of the scheduled entity, a DU slot interpretation to be applied by the scheduled entity to slots including downlink-uplink (DU) symbols; and a unit for sending the DU slot interpretation to the scheduled entity. DU symbols may be configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). In one aspect, the aforementioned unit may be in… Figure 10The diagram shows a processor 1004 configured to perform the functions described above. Alternatively, the aforementioned unit may be a circuit or any device configured to perform the functions described above.

[0149] In another example, a scheduling entity for wireless communication may include: a unit for obtaining the duplex mode of the scheduled entity; a unit for selecting an HDDU time slot interpretation (if the duplex mode is HD) from a plurality of differentiated HDDU time slot interpretations, each of the plurality of differentiated HDDU time slot interpretations determining how the scheduled entity can interpret at least one DU symbol; and a unit for transmitting a first value indicating the selected HDDU time slot interpretation to the scheduled entity via Radio Resource Control (RRC) signaling. Further, the scheduling entity may include: a unit for selecting an FD-aware DU time slot interpretation (if the duplex mode is FD-aware) from a plurality of differentiated FD-aware DU time slot interpretations, each of the plurality of differentiated FD-aware DU time slot interpretations determining how the scheduled entity can interpret at least one DU symbol; and a unit for transmitting a second value indicating the selected FD-aware DU time slot interpretation to the scheduled entity via Radio Resource Control (RRC) signaling. In one aspect, the above-mentioned units may be in… Figure 10 The diagram shows a processor 1004 configured to perform the functions described above. Alternatively, the aforementioned unit may be a circuit or any device configured to perform the functions described above.

[0150] Figure 13 This is a block diagram illustrating an example of a hardware implementation of a scheduled entity 1300 employing a processing system 1302 according to some aspects of this disclosure. For example, the scheduled entity 1300 may be as shown in... Figure 1 , Figure 2 And / or any one or more of the user equipment (UE) or other scheduled entities shown in Figure 4.

[0151] Processing system 1302 can be connected with Figure 10 The processing system 1002 shown is substantially the same as that described above, including a bus interface 1312, a bus 1306, a memory 1308, a processor 1304, and a computer-readable medium 1310. According to various aspects of this disclosure, any element, any part of an element, or any combination of elements can be implemented using the processing system 1302, which includes one or more processors (such as processor 1304). Furthermore, the scheduled entity 1300 may include a user interface 1318, a transceiver 1314, an antenna / antenna array / antenna module (hereinafter referred to as antenna 1316), and a power supply 1320, which are similar to those described above. Figure 10Those described in the text are essentially similar. For example, the processor 1304 utilized in the scheduled entity 1300 can be used to implement, for example, [the following text is missing from the original] Figure 11 , Figure 12 , Figure 14 and / or Figure 15 Any one or more processes described and illustrated in this article.

[0152] In some aspects of this disclosure, processor 1304 may include communication and processing circuitry 1341 configured for various functions, including, for example, communicating with a scheduling entity (e.g., a base station, such as a gNB), a network core (e.g., a 5G core network), other scheduled entities, or any other entity (such as, for example, local infrastructure, or an entity communicating with scheduled entity 1300 via the Internet, such as a network provider)). In some examples, communication and processing circuitry 1341 may also be configured to receive and process messages from a scheduling entity indicating that a time slot can be formatted with at least one downlink-uplink (DU) symbol, the at least one DU symbol being reserved for simultaneous downlink and uplink transmissions in the same carrier bandwidth (e.g., in the same frequency band). In some examples, communication and processing circuitry 1341 may also be configured to receive and process messages from a scheduling entity indicating DU symbol or DU time slot interpretation that the scheduled entity can use to interpret DU symbols or DU time slots. In some examples, the communication and processing circuitry 1341 may include one or more hardware components providing a physical structure that performs processes related to wireless communication (e.g., signal reception and / or signal transmission) and signal processing (e.g., processing received signals and / or processing signals for transmission). Furthermore, the communication and processing circuitry 1341 may be configured to receive and process downlink traffic and downlink control (e.g., similar to...). Figure 1 The communication and processing circuitry 1341 can also be configured to execute communication and processing software 1351 stored on a computer-readable medium 1310 to perform one or more of the functions described herein. This includes downlink services 112 and downlink control 114, as well as processing and transmitting uplink services and uplink control (e.g., similar to uplink service 116 and uplink control 118).

[0153] In some aspects of this disclosure, processor 1304 may include DU symbol and / or DU time slot interpretation selection circuitry 1342, configured for various functions, including, for example, selecting DU symbol and / or DU time slot interpretation for interpreting DU symbols in time slots and / or DU time slots (including at least one DU symbol), respectively. In some aspects of this disclosure, DU symbol and / or DU time slot interpretation selection circuitry 1342 may be configured for various functions, including, for example, selecting DU time slot interpretation to be applied to time slots including DU symbols based on the duplex mode of the scheduled entity 1300. For example, if the scheduled entity is an HD or FD-aware scheduled entity that can be pre-configured to interpret at least one DU symbol, selection can be made according to pre-configured instructions 1309. For example, pre-configured instructions 1309 may be stored on memory 1308. According to some aspects, the DU symbol and / or DU time slot interpretation selection circuit 1342 may also receive instructions or other communications (e.g., "first value" or "second value") from the scheduled entity, which may indicate that one or more DU symbols and / or DU time slots may be selected and / or used by the scheduled entity to interpret a time slot (e.g., a DU time slot) formatted as having at least one DU symbol.

[0154] According to some examples, if the duplex mode of the scheduled entity is half-duplex (HD), then the DU slot interpretation (whether pre-configured by the scheduled entity, sent to the scheduled entity by the scheduling entity, determined by the scheduled entity, or obtained in another manner) may include at least one of the following: a first DU slot interpretation that causes the scheduled entity to treat a first slot format indicator (SFI) including slot information for slots containing DU symbols (or, according to some aspects, a first slot format indicator (SFI) indicating slots containing DU symbols) as an error; a second DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot containing DU symbols as a flexible (F) symbol; a third DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot containing DU symbols as a flexible (F) symbol. Each DU symbol in the time slot is treated as a downlink (DL) symbol; the fourth DU time slot interpretation causes the scheduled entity to perform at least one of the following: treat all DU symbols in the time slot containing the DU symbol, followed by one or more DL symbols, as DL symbols; treat all F symbols in the time slot containing the DU symbol, followed by one or more DL symbols, as DL symbols; treat all UL symbols in the time slot containing the DU symbol, followed by one or more DU symbols, as UL symbols; or treat all F symbols in the time slot containing the DU symbol, followed by one or more DU symbols, as UL symbols; or the fifth DU time slot interpretation causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI.

[0155] According to some examples, if the duplex mode of the scheduled entity is full-duplex aware (FD-aware), then the DU time slot interpretation (whether pre-configured by the scheduled entity, sent to the scheduled entity by the scheduling entity, determined by the scheduled entity, or obtained in another manner) may include at least one of the following: a first DU time slot interpretation that causes the scheduled entity to treat all symbols in the time slot containing the DU symbol as DL symbols or UL symbols according to parameters pre-configured in the scheduled entity; a second DU time slot interpretation that causes the scheduled entity to treat all symbols in the time slot containing the DU symbol according to RRC parameters; and a third DU time slot interpretation that causes the scheduled entity to treat all symbols in the time slot containing the DU symbol as flexible (F) symbols, wherein the physical downlink control channel (PDCCH) determines that an F symbol is considered a flexible (F) symbol. Is it an uplink (UL) symbol or a downlink (DL) symbol?; Fourth DU slot interpretation, which causes the scheduled entity to perform at least one of the following: treat all DU symbols in a slot that includes a DU symbol and is followed by one or more DL symbols as DL symbols; treat all F symbols in a slot that includes a DU symbol and is followed by one or more DL symbols, as well as one or more DU symbols, as DL symbols; treat all UL symbols in a slot that includes a DU symbol and is followed by one or more DU symbols as UL symbols; or treat all F symbols in a slot that includes a DU symbol and is followed by one or more DU symbols as UL symbols; or Fifth DU slot interpretation, which causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI.

[0156] In some examples, the DU symbol and / or DU time slot interpretation selection circuit 1342 may include one or more hardware components that provide a physical structure for performing processes related to performing DU symbol and / or DU time slot interpretation selection. The DU symbol and / or DU time slot interpretation selection circuit 1342 may also be configured to execute DU symbol and / or DU time slot interpretation selection software 1352 stored on a computer-readable medium 1310 to implement one or more of the functions described herein.

[0157] In some aspects of this disclosure, processor 1304 may include DU time slot interpretation application circuitry 1343, configured for various functions, including, for example, applying DU time slot interpretation to time slots, wherein DU symbols are configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). DU time slot interpretation application circuitry 1343 may also be configured to execute DU time slot interpretation application processing software 1353 stored on computer-readable medium 1310 to implement one or more of the functions described herein.

[0158] Figure 14 This is a flowchart illustrating an exemplary process 1400 (e.g., a wireless communication method) at a scheduled entity in a wireless communication network according to some aspects of this disclosure. According to some aspects, the scheduled entity may be a half-duplex (HD) or full-duplex (FD) sensed entity. According to some aspects of this disclosure, the scheduled entity may interpret at least one DU symbol in a time-slot format. As described below, in certain implementations within the scope of this disclosure, some or all of the features shown may be omitted, and some of the shown features may not be required for all example implementations. In some examples, process 1400 may be performed by... Figure 13 The scheduled entity 1300 shown is responsible for execution. In some examples, process 1400 may be executed by any suitable means or unit for performing the functions or algorithms described herein.

[0159] At box 1402, the scheduled entity (e.g., UE or other wireless communication device) can receive a message indicating that a time slot can be formatted with downlink-uplink (DU) symbols reserved for downlink and uplink transmissions. DU symbols can be configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). Downlink and uplink transmissions can occur simultaneously within the same carrier bandwidth (e.g., within the same frequency band). For example, the message can be a downlink control information (DCI) format message. According to one example, the DCI format could be DCI format 2_0. For example, the above combined... Figure 13 The communication and processing circuitry 1341 and / or transceiver 1314 and antenna 1316 shown and described can provide a unit for receiving messages that can be formatted as having time slots with downlink-uplink (DU) symbols reserved for downlink and uplink transmission.

[0160] At box 1404, the scheduled entity can select the DU slot interpretation to be applied to the slots including DU symbols based on the duplex mode of the scheduled entity. DU symbols can be configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., within the same frequency band). According to some aspects, the scheduled entity may have been pre-configured with a DU slot interpretation that can be applied to the slots including DU symbols based on the duplex mode of the scheduled entity; therefore, selection of a DU slot interpretation from, for example, a plurality of diverse DU slot interpretations may not be required. For example, in conjunction with the above... Figure 13 The DU symbol and / or DU slot interpretation selection circuit 1342 shown and described can provide a unit for selecting the DU slot interpretation to be applied to the slot including the DU symbol based on the duplex mode of the scheduled entity.

[0161] At box 1406, the scheduled entity can apply the DU time slot interpretation to the time slot. For example, in conjunction with the above... Figure 13 The DU time slot interpretation application circuit 1343 shown and described can provide a unit for applying DU time slot interpretation to time slots.

[0162] Depending on several aspects, a DU symbol can differ from a downlink (DL) symbol, an uplink (UL) symbol, and a flexible (F) symbol. In one example, the uplink and downlink may partially or completely overlap within the carrier bandwidth of the DU symbol. In another example, the uplink and downlink may occur simultaneously at different non-overlapping frequencies within the DU symbol. According to some examples, before selecting a DU slot interpretation, the scheduled entity may receive a first value indicating the DU slot interpretation to be applied to the slots including the DU symbol. For example, the first value may be received from the scheduled entity in RRC signaling.

[0163] In some examples, the DL and UL symbols are reserved for DL ​​and UL respectively when: at the same first time at different respective first frequencies in a paired spectrum, or at different respective second times at the same second frequency. The F symbol can be interpreted as either a UL symbol or a DL symbol. The DU symbol is reserved for DL ​​and UL when: at the same third time at different respective third frequencies in an unpaired spectrum (e.g., Figure 5D Reference number 530; or Figure 6B (Ref. 602), or for example, at the same fourth time at the same fourth frequency in the unpaired spectrum (e.g., Figure 6A (Ref. 614).

[0164] In some examples, the different respective first frequencies in a paired spectrum may have a first guard band between them. The different respective third frequencies in an unpaired spectrum may have a second guard band between them, and the second guard band may be smaller than the first guard band.

[0165] In some examples, if the duplex mode of the scheduled entity is half-duplex (HD), then at box 1404, selecting the DU slot interpretation may further include selecting at least one of the following: a first DU slot interpretation that causes the scheduled entity to treat a first slot format indicator (SFI) that includes slot information for slots containing DU symbols (or, depending on some aspects, a first slot format indicator (SFI) that indicates slots containing DU symbols) as an error; a second DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot containing DU symbols as a flexible (F) symbol; and a third DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot containing DU symbols as a downlink (D) symbol. L) symbol; Fourth DU slot interpretation, which causes the scheduled entity to perform at least one of the following: treat all DU symbols in a slot containing a DU symbol, followed by one or more DL symbols, as DL symbols; treat all F symbols in a slot containing a DU symbol, followed by one or more DL symbols, as DL symbols; treat all UL symbols in a slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or treat all F symbols in a slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or Fifth DU slot interpretation, which causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. For example, the reserved SFI may indicate a slot formatted to have all DL symbols or all UL symbols. For example, slot information may include at least one of the following: Slot Format Indication (SFI), Slot Format Combination Identifier (SlotFormatCombinationID), Slot Format Number or ID, Symbol Type or Symbol Position.

[0166] According to other examples, if the duplex mode of the scheduled entity is full-duplex aware (FD aware), where the scheduled entity is aware of full-duplex time slots including DU symbols, then at box 1404, selecting the DU time slot interpretation may further include selecting at least one of the following: a first DU time slot interpretation, which causes the scheduled entity to treat all symbols in the time slot including DU symbols as DL symbols or UL symbols according to parameters pre-configured in the scheduled entity; a second DU time slot interpretation, which causes the scheduled entity to treat all symbols in the time slot including DU symbols according to RRC parameters; a third DU time slot interpretation, which causes the scheduled entity to treat all symbols in the time slot including DU symbols as flexible (F) symbols, where the physical downlink control channel (PDCCH) determines whether an F symbol is treated as an uplink (UL) symbol or a downlink (DL) symbol; a fourth DU time slot interpretation, This causes the scheduled entity to perform at least one of the following: treat all DU symbols in a time slot that includes a DU symbol, followed by one or more DL symbols, as DL symbols; treat all F symbols in a time slot that includes a DU symbol, followed by one or more DL symbols, and one or more DU symbols as DL symbols; treat all UL symbols in a time slot that includes a DU symbol, followed by one or more DU symbols, as UL symbols; or treat all F symbols in a time slot that includes a DU symbol, followed by one or more DU symbols, as UL symbols; or interpret a fifth DU time slot, which causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. The reserved SFI may indicate a time slot formatted to have all DL symbols or all UL symbols.

[0167] Figure 15 This is a flowchart illustrating another exemplary process 1500 (e.g., a wireless communication method) at a scheduled entity in a wireless communication network according to some aspects of this disclosure. According to some aspects, the scheduled entity may be a half-duplex (HD) or full-duplex (FD) sensed entity. According to some aspects of this disclosure, the scheduled entity may interpret at least one DU symbol in a time-slot format. As described below, in certain implementations within the scope of this disclosure, some or all of the features shown may be omitted, and some of the shown features may not be required for all example implementations. In some examples, process 1500 may be performed by... Figure 13 The scheduled entity 1300 shown is responsible for execution. In some examples, process 1500 may be executed by any suitable means or unit for performing the functions or algorithms described herein.

[0168] At box 1502, the scheduled entity (e.g., UE or other wireless communication device) may receive a message indicating that a time slot can be formatted with at least one downlink-uplink (DU) symbol, which is reserved for simultaneous downlink and uplink transmissions in the same carrier bandwidth (e.g., within the same frequency band). For example, this message may be a downlink control information (DCI) format message. According to one example, the DCI format may be DCI format 2_0. For example, the above combined... Figure 13 The communication and processing circuitry 1341 and / or transceiver 1314 and antenna 1316 shown and described may provide a unit for receiving a message indicating that the time slot can be formatted to have at least one downlink-uplink (DU) symbol, the at least one DU symbol being reserved for simultaneous downlink and uplink transmissions in the same carrier bandwidth (e.g., in the same frequency band).

[0169] At box 1504, the scheduled entity can determine whether it is pre-configured to interpret at least one DU symbol. For example, in conjunction with the above... Figure 13 The communication and processing circuitry 1341 and memory 1308 shown and described may provide units for determining whether a scheduled entity is pre-configured to interpret at least one DU symbol. Pre-configured instructions 1309 may, for example, be stored in memory 1308.

[0170] If the scheduled entity is pre-configured to interpret at least one DU symbol, then at box 1506, the scheduled entity can interpret at least one DU symbol according to the pre-configured instructions. For example, in conjunction with the above... Figure 13 The DU symbol and / or DU time slot interpretation selection circuit 1342 shown and described can provide a unit for interpreting at least one DU symbol according to pre-configured instructions.

[0171] If the scheduled entity is not pre-configured to interpret at least one DU symbol, then at box 1508, the scheduled entity can choose to determine how the scheduled entity can interpret the HDDU slot interpretation or FD-aware DU slot interpretation of at least one DU symbol. The selection can be made from multiple distinct HDDU slot interpretations or FD-aware DU slot interpretations, respectively. For example, the above combined... Figure 13 The DU symbol and / or DU slot interpretation selection circuit 1342 shown and described may provide a unit for selecting how the scheduled entity can interpret at least one DU symbol's HDDU slot interpretation or FD-aware DU slot interpretation.

[0172] At box 1510, the scheduled entity can interpret at least one DU symbol based on the HDDU interpretation selected at box 1508 or the FD-aware DU interpretation selected. For example, in conjunction with the above... Figure 13The DU symbol and / or DU time slot interpretation selection circuit 1342 shown and described can provide a unit for interpreting at least one DU symbol according to the HDDU interpretation or the FD-aware DU interpretation selected at block 1508.

[0173] According to some aspects, before selecting a DU slot interpretation, the scheduled entity may also receive a first value indicating the DU slot interpretation to be applied to the slot containing the DU symbol. According to one example, the first value may be received via Radio Resource Control (RRC) signaling.

[0174] According to one example, if the duplex mode of the scheduled entity is half-duplex (HD), selecting a DU slot interpretation may include selecting at least one of the following: a first DU slot interpretation that causes the scheduled entity to treat a first slot format indicator (SFI) that includes slot information for a slot containing DU symbols (or, depending on some aspect, a first slot format indicator (SFI) that indicates a slot containing DU symbols) as an error; a second DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot containing DU symbols as a flexible (F) symbol; and a third DU slot interpretation that causes the scheduled entity to treat each DU symbol in a slot containing DU symbols as a downlink (DL) symbol. The fourth DU time slot interpretation causes the scheduled entity to perform at least one of the following: treat all DU symbols in a time slot containing a DU symbol, followed by one or more DL symbols, as DL symbols; treat all F symbols in a time slot containing a DU symbol, followed by one or more DL symbols, as DL symbols; treat all UL symbols in a time slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or treat all F symbols in a time slot containing a DU symbol, followed by one or more DU symbols, as UL symbols; or the fifth DU time slot interpretation causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. According to one aspect, the reserved SFI may indicate a time slot formatted to have all DL symbols or all UL symbols.

[0175] According to another example, if the duplex mode of the scheduled entity is full-duplex aware (FD-aware), then selecting the DU slot interpretation may include selecting at least one of the following: a first DU slot interpretation, which causes the scheduled entity to treat all symbols in the slot containing the DU symbol as either DL symbols or UL symbols according to parameters pre-configured in the scheduled entity; a second DU slot interpretation, which causes the scheduled entity to treat all symbols in the slot containing the DU symbol according to RRC parameters; and a third DU slot interpretation, which causes the scheduled entity to treat all symbols in the slot containing the DU symbol as flexible (F) symbols, wherein the physical downlink control channel (PDCCH) determines whether an F symbol is treated as an uplink (UL) symbol or a downlink (DL) symbol. The fourth DU time slot interpretation causes the scheduled entity to perform at least one of the following: treating all DU symbols in a time slot including a DU symbol, followed by one or more DL symbols, as DL symbols; treating all F symbols in a time slot including a DU symbol, followed by one or more DL symbols, and one or more DU symbols as DL symbols; treating all UL symbols in a time slot including a DU symbol, followed by one or more DU symbols, as UL symbols; or treating all F symbols in a time slot including a DU symbol, followed by one or more DU symbols, as UL symbols; or the fifth DU time slot interpretation causes the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. According to one aspect, the reserved SFI may indicate a time slot formatted to have all DL symbols or all UL symbols.

[0176] The exemplary process 1500 may further include, for example, receiving a first value indicating how the scheduled entity can interpret the DU slot interpretation of at least one DU symbol if the scheduled entity is not pre-configured to interpret at least one DU symbol. The received first value may indicate, for example, one of five alternative DU slot interpretations. The exemplary process may further include receiving the first value via RRC signaling.

[0177] According to some aspects, at least one DU symbol may be different from the uplink (UL) symbol, downlink (DL) symbol, and flexible (F) symbol, because the DL and UL symbols are reserved for DL ​​and UL transmissions that are performed simultaneously at different frequencies or at different times at the same frequency, and the F symbol can be interpreted as either a UL symbol or a DL symbol.

[0178] In one example, if the scheduled entity is an HD scheduled entity, the pre-configured instructions may cause the wireless device to perform at least one of the following: treat a first time slot format indicator (SFI) including time slot information for a time slot including at least one DU symbol (or, according to some aspects, treat a first time slot format indicator (SFI) indicating a time slot including at least one DU symbol as an error; treat each DU symbol in a time slot formatted according to the first SFI as a flexible (F) symbol; treat each DU symbol in a time slot formatted according to the first SFI as a downlink (DL) symbol; or may also cause the scheduled entity to perform at least one of the following: treat each DU symbol in a time slot formatted according to the first SFI as an error. All DU symbols in a time slot formatted by the first SFI, followed by one or more DL symbols, are considered DL symbols; all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DL symbols, are considered DL symbols; all UL symbols in a time slot defined by the first SFI, followed by one or more DU symbols, are considered UL symbols; or all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DU symbols, are considered UL symbols; or the scheduled entity may replace the first SFI with a reserved SFI having content different from the first SFI. According to some aspects, the reserved SFI may indicate a time slot formatted with all DL symbols or all UL symbols.

[0179] In another example, if the scheduled entity is a half-duplex scheduled entity, the multiple differentiated HDDU slot interpretations may include at least one of the following: HD first DU slot interpretation, which causes the scheduled entity to treat a first slot format indicator (SFI) including slot information for a slot comprising at least one DU symbol (or, according to some aspects, a first slot format indicator (SFI) indicating a slot comprising at least one DU symbol) as an error; HD second DU slot interpretation, which causes the scheduled entity to treat each DU symbol in a slot formatted according to the first SFI as a flexible (F) symbol; HD third DU slot interpretation, which causes the scheduled entity to treat each DU symbol in a slot formatted according to the first SFI as a downlink (DL) symbol; HD fourth DU slot interpretation. The interpretation causes the scheduled entity to perform at least one of the following: treat all DU symbols in a time slot formatted according to the first SFI, followed by one or more DL symbols, as DL symbols; treat all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DL symbols, as DL symbols; treat all UL symbols in a time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or treat all F symbols and one or more DU symbols in a time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or interpret the HD fifth DU time slot, causing the scheduled entity to replace the first SFI with a reserved SFI having content different from the first SFI. According to some aspects, the reserved SFI may indicate a time slot formatted to have all DL symbols or all UL symbols.

[0180] According to one aspect, if the scheduled entity is an FD-aware scheduled entity, the pre-configured instructions may cause the scheduled entity to operate in UL mode or DL ​​mode depending on at least one of the following: a default mode pre-configured in the scheduled entity; an RRC parameter that determines whether at least one DU symbol can be replaced by a DL symbol or a UL symbol; a PDCCH that is monitored to determine whether at least one DU symbol can be replaced by a DL symbol or a UL symbol; DU slot interpretation that causes the scheduled entity to use a reserved SFI used with an FD-aware scheduled entity instead of a first SFI; or DU slot interpretation that causes the scheduled entity to perform at least one of the following: treating all DU symbols in a slot formatted according to the first SFI, followed by one or more DL symbols, as DL symbols; treating all F symbols and one or more DU symbols in a slot defined by the first SFI, followed by one or more DL symbols, as DL symbols; treating all UL symbols in a slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or treating all F symbols and one or more DU symbols in a slot defined by the first SFI, followed by one or more DU symbols, as UL symbols. In one example, a reserved SFI can indicate a time slot formatted to have all DL symbols or all UL symbols.

[0181] In another example, if the scheduled entity is an FD-aware scheduled entity, the multiple differentiated FD-aware DU time slot interpretations may include at least one of the following: an FD-aware first DU time slot interpretation based on a default mode pre-configured in the scheduled entity; an FD-aware second DU time slot interpretation based on RRC parameters, which determine whether at least one DU symbol can be replaced by a DL symbol or a UL symbol; an FD-aware third DU time slot interpretation based on PDCCH, which can be monitored to determine whether at least one DU symbol can be replaced by a DL symbol or a UL symbol; and an FD-aware fourth DU time slot interpretation that allows the scheduled entity to utilize reserved S... used with the FD-aware scheduled entity. FI replaces the first SFI; or FD perceives the interpretation of the fifth DU time slot, which causes the scheduled entity to perform at least one of the following: treat all DU symbols in the time slot formatted according to the first SFI, followed by one or more DL symbols, as DL symbols; treat all F symbols and one or more DU symbols in the time slot defined by the first SFI, followed by one or more DL symbols, as DL symbols; treat all UL symbols in the time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols; or treat all F symbols and one or more DU symbols in the time slot defined by the first SFI, followed by one or more DU symbols, as UL symbols. According to some aspects, a reserved SFI may indicate a time slot formatted with all DL symbols or all UL symbols.

[0182] Depending on some aspects, for both FD-aware and FD-scheduled entities, the DU slots identified in the DCI format 2_0 message can exhibit some FDD-like behavior. For example, the slot format pattern (e.g., Figure 8 The three slot format modes of SlotFormatCombinationID 802 can be repeated. In another example, the DU slot interpretation after receiving DCI 2_0 can override the public or private slot mode configuration. That is, the SFI can override the public or private slot mode configuration (which is the RRC configuration). Depending on other aspects, for FD-aware and FD-scheduled entities, the DU slot identified in the DCI format 2_0 message can have some TDD-like behavior. For example, PDCCH monitoring can determine the period and length of the slot (as performed in TDD duplex mode) to obtain the upcoming slot format mode. In another example, a newly acquired SFI can override a flexible slot or flexible symbol defined by an existing SFI using the indicated slot or symbol defined respectively in the newly acquired SFI.

[0183] In one example, the scheduled entity may include: a unit for receiving a message indicating that a time slot can be formatted with downlink-uplink (DU) symbols, the DU symbols being reserved for simultaneous downlink and uplink transmissions in the same carrier bandwidth (e.g., in the same frequency band); a unit for selecting DU time slot interpretation to be applied to time slots including DU symbols based on the duplex mode of the scheduled entity; and a unit for applying DU time slot interpretation to time slots, wherein the DU symbols can be configured to include downlink and uplink transmissions within the same carrier bandwidth (e.g., in the same frequency band).

[0184] In another example, the scheduled entity may include: a unit for decoding a message indicating that the time slot is formatted to have at least one downlink-uplink (DU) symbol, the at least one DU symbol being reserved for simultaneous downlink and uplink transmissions in the same carrier bandwidth (e.g., in the same frequency band); and a unit for determining whether the scheduled entity is pre-configured to interpret at least one DU symbol. If the scheduled entity is pre-configured to interpret at least one DU symbol, the scheduled entity may further include a unit for interpreting at least one DU symbol according to pre-configured instructions. If the scheduled entity is not pre-configured to interpret at least one DU symbol, the scheduled entity may further include a unit for selecting from a plurality of distinct HDDU time slot interpretations or FD-aware DU time slot interpretations how the scheduled entity can interpret at least one DU symbol.

[0185] In one aspect, the aforementioned unit may be in Figure 13 The processor 1304 shown is configured to perform the functions described by the aforementioned unit. Alternatively, the aforementioned unit may be a circuit or any device configured to perform the functions described by the aforementioned unit.
