[0002] This patent application claims priority to U.S. Patent Application No. 18 / 358,746, filed July 25, 2023, entitled “SUB-BAND FULL-DUPLEX GRANULARITY,” which is assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] All aspects of this disclosure relate to wireless communication in general, and to techniques and apparatus for subband full-duplex granularity. Background Technology

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

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with network nodes via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, etc.).

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink; and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technologies and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0018] To gain a full understanding of the foregoing features of this disclosure, a more specific description of the invention, briefly outlined above, can be obtained by referring to various aspects, some of which are illustrated in the accompanying drawings. However, it should be noted that the drawings illustrate only certain typical aspects of this disclosure and are therefore not to be considered as limiting its scope, as the description acknowledges other equally valid aspects.

[0027] Figure 9 This is a diagram of an example device for wireless communication according to the present disclosure. Detailed Implementation

[0028] The subcarrier spacing (SCS) of the bandwidth portion (BWP) can be greater than or equal to the SCS of a time-division duplex (TDD) uplink (UL) downlink (DL) (TDD-UL-DL) configuration. Additionally, the SCS of the BWP can be greater than or equal to the SCS of the slot format indicator (SFI). A BWP SCS greater than the SCS of the TDD-UL-DL configuration may result in one or more slot types being duplicated. For example, a DDDU mode (where D corresponds to downlink resources and U corresponds to uplink resources) under a 30 kHz SCS may become DDDDDDUU under a 60 kHz SCS. In the first example, to indicate the SBFD mode in the time domain, the SCS of the SBFD mode can be the same as the SCS of the TDD-UL-DL configuration. In the second example, to indicate the SBFD mode in the time domain, the SCS of the SBFD mode can be different from the SCS of the TDD-UL-DL configuration. In some cases, the user equipment (UE) and network node may be unable to determine whether the SCS used for SBFD resources is the same in the time and frequency domains, or whether the SCS used for SBFD resources differs in the time domain from that in the frequency domain. Additionally or alternatively, the UE and network node may be unable to determine the time-domain and frequency-domain granularity of the SBFD mode for SBFD resources.

[0029] Various aspects are involved in wireless communication as a whole. Some aspects are more specifically involved in identifying the SBFD granularity used for SBFD communication. In some examples, a network node may send an SBFD mode indication indicating the SBFD mode used for SBFD resources, and a UE may receive the SBFD mode indication indicating the SBFD mode used for SBFD resources. In some examples, the SBFD mode may be a semi-static SBFD mode included in a common cell configuration. In some other examples, the SBFD mode may be a semi-static SBFD mode included in a UE-specific configuration. In some examples, the SBFD mode may be a slot-based SBFD mode. In some other examples, the SBFD mode may be a symbol-based SBFD mode. The UE may identify the time-domain granularity and frequency-domain granularity of the SBFD resources based at least in part on the SBFD mode indication. The UE and network node may communicate via SBFD resources according to the time-domain granularity and frequency-domain granularity. In some examples, a network node may send an updated SBFD mode via dynamic signaling (such as Layer 1 or Layer 2 signaling), and the UE may receive the updated SBFD mode via dynamic signaling (such as Layer 1 or Layer 2 signaling). The UE can identify the update time-domain granularity and update frequency-domain granularity of the SBFD resources according to the update SBFD mode, and the UE and network nodes can communicate via the SBFD resources according to the update time-domain granularity and update frequency-domain granularity.

[0030] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques can be used to enable a UE to identify the time-domain granularity and frequency-domain granularity of an SBFD resource by conveying an SBFD mode indication that indicates the SBFD mode used for the SBFD resource. Additionally, by identifying the time-domain granularity and frequency-domain granularity of the SBFD resource, the described techniques can be used to enable a UE and a network node to determine whether the SCS used for the SBFD resource is the same in the time and frequency domains, or whether the SCS used for the SBFD resource is different in the time domain than in the frequency domain. This can improve communication on SBFD resources and reduce lost communication on SBFD resources. These example advantages, etc., will be described in more detail below.

[0031] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure can be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods implemented using structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the present claims.

[0032] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0033] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0034] Figure 1This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0035] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0036] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0037] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device can include more than one base station.

[0038] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions for other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, repeater, etc.

[0039] Wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0040] Network controller 130 may be coupled to or communicate with a group of network nodes 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0041] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, a UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0042] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0044] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary device to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0045] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0046] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have designated the operating bands for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been designated as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0047] Considering the examples above, unless otherwise specifically stated, it should be understood that when the term "below 6 GHz" is used herein, it can broadly refer to frequencies below 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that when the term "millimeter wave" is used herein, it can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0048] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive an SBFD mode indication indicating an SBFD mode for an SBFD resource; identify the time-domain granularity and frequency-domain granularity of the SBFD resource based at least in part on the SBFD mode indication; and communicate via the SBFD resource according to the time-domain granularity and the frequency-domain granularity. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0049] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may send an SBFD mode indication indicating an SBFD mode for an SBFD resource; and communicate via the SBFD resource with time-domain and frequency-domain granularity based at least in part on the SBFD mode indication. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0050] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0051] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to this disclosure. Network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). Network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and modems 232. In some examples, network node 110 may include an interface, communication components, or another component facilitating communication with UE 120 or another network node. Some network nodes 110 may not include radio frequency components facilitating direct communication with UE 120, such as one or more CUs or one or more DUs.

[0052] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or a group of UEs 120). Transmitting processor 220 can select one or more modulation and decoding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Partitioning Information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., Cell-Specific Reference Signal (CRS) or Demodulation Reference Signal (DMRS)) and synchronization signals (e.g., Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0053] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110 and can provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.

[0054] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0055] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements and / or be coupled to one or more transmitting and / or receiving components (such as...). Figure 2 One or more antenna elements (one or more components in a )

[0056] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. This transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figures 5 to 9 ( ) any aspect of the methods described in the method.

[0057] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 5 to 9 ( ) any aspect of the methods described in the method.

[0058] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component may perform one or more techniques associated with SBFD granularity, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions may cause the one or more processors, UE 120 and / or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, transformation and / or interpretation). Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transformation instructions, compilation instructions, and / or interpretation instructions, etc.

[0059] In some aspects, UE 120 includes components for receiving an SBFD mode indication indicating an SBFD mode for an SBFD resource; components for identifying the time-domain granularity and frequency-domain granularity of the SBFD resource based at least in part on the SBFD mode indication; and / or components for communicating via the SBFD resource according to the time-domain granularity and the frequency-domain granularity. Components enabling UE 120 to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0060] In some aspects, network node 110 includes components for transmitting an SBFD mode indication indicating an SBFD mode for an SBFD resource; and / or components for communicating via the SBFD resource with time-domain and frequency-domain granularity, the time-domain granularity and the frequency-domain granularity being at least partially based on the SBFD mode indication. Components enabling network node 110 to perform the operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0061] In some respects, a single processor can perform all the functions described as being performed by that one or more processors. In other respects, the one or more processors can jointly perform a set of functions. For example, a first group(s) of the one or more processors can perform a first function described as being performed by that one or more processors, and a second group(s) of the one or more processors can perform a second function described as being performed by that one or more processors. The first group and the second group of processors can be the same group of processors or can be different groups of processors. The reference to "one or more processors" should be understood as referring to a combination of functions. Figure 2 Any one or more processors described. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as those in conjunction with... Figure 2 The memory described. For example, a function described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0062] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0063] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0064] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in either a converged or decomposed architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or components) performing base station functionality can be implemented as a converged base station (also known as a standalone base station or monolithic base station) or a decomposed base station. A "network entity" or "network node" can refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof).

[0065] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0066] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed independently. Decomposed base stations can include functionality implemented across two or more units at various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0067] Figure 3This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0068] Each unit in the cells (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cell, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other cells via transmission media. In some examples, each unit in the cell may include a wired interface and a wireless interface configured to receive signals or transmit signals to one or more units in other cells via a wired transmission media, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more units in other cells via a wireless transmission media, or both.

[0069] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0070] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), Digital Beamforming, or Physical Random Access Channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0071] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In such architectures, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0072] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTTRIC 325. In some specific implementations, the SMO framework 305 may communicate with the hardware aspects of the 4G RAN, such as the Open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0073] The non-RT RIC 315 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as via an E2 interface, through data collection and action, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0074] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0075] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0076] Figure 4 These are illustrations of examples 400, 405, and 410 of full-duplex communication in a wireless network according to this disclosure. Full-duplex (FD) communication in a wireless network refers to simultaneous bidirectional communication between devices in the wireless network. For example, a UE operating in full-duplex mode can simultaneously (e.g., in the same time slot or the same symbol) transmit uplink communication and receive downlink communication. Half-duplex (HD) communication in a wireless network refers to unidirectional communication (e.g., downlink communication only or uplink communication only) between devices at a given time (e.g., in a given time slot or a given symbol).

[0077] like Figure 4As shown, Examples 400 and 405 illustrate examples of in-band full-duplex (IBFD) communication. In IBDF, a UE can send uplink communication to and receive downlink communication from a base station on the same time and frequency resources. As shown in Example 400, in the first example of IBDF, the time and frequency resources used for uplink communication may completely overlap with those used for downlink communication. As shown in Example 405, in the second example of IBDF, the time and frequency resources used for uplink communication may partially overlap with those used for downlink communication.

[0078] like Figure 4 As further illustrated, Example 410 shows an example of Subband Full-Duplex (SBFD) communication, which can also be referred to as Subband Frequency Division Duplex (SBFDD) or Flexible Duplex. In SBFD, the UE can send uplink communication to the base station and receive downlink communication from the base station at the same time but on different frequency resources. For example, different frequency resources can be subbands of a frequency band such as a time-division duplex band. In this case, the frequency resources used for downlink communication can be separated from the frequency resources used for uplink communication in the frequency domain by guard bands.

[0079] In some cases, such as for semi-static SBFD, to avoid frequent switching between SBFD and non-SBFD symbols, a limit on the maximum number of transition points between SBFD and non-SBFD symbols can be considered. For example, a maximum of two transition points within a TDD UL / DL mode cycle (including one transition point from a non-SBFD symbol to an SBFD symbol and one transition point from an SBFD symbol to a non-SBFD symbol) can be considered, where the transition point will be aligned with a slot boundary or within a slot. In some cases, such as depending on the specific implementation of the network node or UE and / or SBFD operation, a protection period (e.g., a protection band) between SBFD and non-SBFD symbols can be used at the network node and / or at the UE. In some cases, the reference SCS configured in TDD-UL-DL mode in the cell configuration can be less than or equal to the SCS of the BWP. In some cases, the UE may expect the reference SCS to be configured with μ. ref Less than or equal to the SCS configuration μ used for any configured DL BWP or UL BWP. Each time slot provided by the first mode (Mode 1) or the second mode (Mode 2) can be applied to 2 active DL BWPs or active UL BWPs. (µ-µref) A series of consecutive time slots, the first of which is used for reference SCS configuration μ ref The first time slot starts simultaneously and is used to reference the SCS configuration μ refEach downlink, flexible, or uplink symbol corresponds to 2 μ for SCS configuration. (µ-µref) A continuous downlink, flexible, or uplink symbol. Additionally, the SCS of the BWP may be greater than or equal to the SCS of the Slot Format Indicator (SFI).

[0080] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0081] Figure 5 This is a diagram illustrating example 500 of SBFD granularity for SBFD communication according to this disclosure. In some aspects, the SBFD time-domain pattern can determine the location of SBFD slots or symbols (or HD slots or symbols). Additionally or alternatively, the granularity of the time-domain pattern can be defined at least in part based on a reference SCS.

[0082] As shown by reference numeral 505 in the accompanying drawings, network node 110 may send an SBFD mode indication indicating an SBFD mode for SBFD resources, and UE 120 may receive the SBFD mode indication indicating an SBFD mode for SBFD resources. In a first example, the SBFD mode indication may be included in a cell common configuration. For example, network node 110 may send a ServingCellConfigCommon indication, and UE 120 may receive a ServingCellConfigCommon indication that includes an indication of an SBFD mode and also includes a TDD-UL-DL configuration common indication. In a second example, the SBFD mode indication may be included in a UE-specific configuration. For example, network node 110 may send a TDD-UL-DL configuration-specific indication, and UE 120 may receive a TDD-UL-DL configuration-specific indication that includes an indication of an SBFD mode.

[0083] As shown by reference numeral 510 in the attached figure, UE 120 can identify the time-domain granularity and frequency-domain granularity of the SBFD resource. UE 120 can identify the time-domain granularity and frequency-domain granularity of the SBFD resource at least in part based on the SBFD mode indication.

[0084] As described in the first example above, UE 120 can receive a serving cell configuration common indication, which includes an indication of the SBFD mode and a TDD-UL-DL configuration common indication. In some aspects, the temporal granularity of the SBFD resources may be at least partially based on a reference SCS defined in the TDD-UL-DL configuration common indication (e.g., may be the same as that reference SCS). Additionally, the frequency domain SCS of the SBFD resources (e.g., used to determine the downlink band, uplink band, or guard band in the SBFD time slot) may differ from the SCS of the active BWP. In some other aspects, the temporal granularity of the SBFD resources may be independent of the SCS of the frequency domain resources used to define the uplink band, downlink band, and guard band. Therefore, the temporal granularity of the SBFD resources may be at least partially based on the temporal granularity of the TDD-UL-DL resources (e.g., may be the same as that of the TDD-UL-DL resources), and the frequency resources (e.g., frequency domain granularity) may be defined separately. For example, a separate SCS can be used to define DL and UL sub-bands.

[0085] As described in the second example above, UE 120 may obtain or receive a UE-specific configuration including an indication of the SBFD mode. In some aspects, the indication of the SBFD mode may be included in a TDD-UL-DL configuration-dedicated instruction. In this case, the SCS associated with the TDD-UL-DL configuration-dedicated instruction may be the same as the reference SCS associated with the TDD-UL-DL configuration-general instruction. For example, the temporal granularity of the SBFD resource may be at least partially based on the reference SCS defined in the TDD-UL-DL configuration-dedicated instruction, and the SCS of the SBFD resource in the frequency domain (used to determine the downlink band, uplink band, or guard band in the SBFD time slot) may differ from the SCS of the active BWP. Alternatively, the temporal granularity of the SBFD resource may be at least partially based on the temporal granularity of the TDD-UL-DL resource, and the frequency resource may be defined separately. In some other aspects, the SBFD temporal mode may be defined according to the ServingCellConfig. In this scenario, a separate SCS can be defined for the SBFD time-domain mode, where the BWP SCS is greater than or equal to the SBFD reference SCS. In one example, no condition needs to be set for the SBFD SCS relative to the TDD-UL-DL configuration common indication. In another example, the SBFD SCS can be greater than or equal to the reference SCS of the TDD-UL-DL configuration common indication. If the SBFD SCS (µ... SBFD The reference SCS (µ) is greater than that of TDD-UL-DL. refThen each time slot in TDD-UL-DL corresponds to 2 in SBFD mode. µSBFD-µref Each time slot. For example, for TDD μ ref =0, SBFD μ SBFD =1, BWP SCS μ=2, each time slot in TDD corresponds to two time slots in SBFD mode, and each time slot in SBFD mode corresponds to two time slots in BWP time slot. For example, the TDD format is "DU", and if each SBFD time slot indicator is 0100, the final bandwidth mode can be DDXXUUUU, where X is the SBFD time slot.

[0086] In some aspects, the SBFD mode indication can be a slot-based SBFD mode indication. This may not allow slots with mixed symbol types (e.g., D symbols and SBFD symbols). In some other aspects, the SBFD mode indication can be a symbol-based SBFD mode indication. This may allow greater flexibility, but long bitmaps or start-end indicators can be used to indicate the mode, which may result in increased overhead. In some other aspects, the SBFD mode indication can be (or may include) a window containing both slot-based and symbol-based indications. This window may be defined at least partially based on the maximum number of switching points between TDD and SBFD. In one example, the slot-based SBFD window may be defined at least partially based on a start indicator and a length indicator, or at least partially based on a start indicator and an end indicator, and the symbol-based SBFD window may be defined at least partially based on a length indicator. This may assume that the symbol-based SBFD window begins directly after the slot-based SBFD window. In another example, a slot-based SBFD window may be defined at least in part based on a start indication and a length indication, or at least in part based on a start indication and an end indication, and a symbol-based SBFD window may be defined at least in part based on a bitmap used to transition slots.

[0087] As shown by reference numeral 515 in the attached figure, UE 120 and network node 110 can communicate via the SBFD resource according to the time domain granularity and the frequency domain granularity.

[0089] In some aspects, the update SBFD mode indication can be at least partially based on a dynamic SBFD update enhanced by the SFI mechanism. For example, the update SBFD mode can be defined at least partially based on the SFI of a reference SCS. In some other aspects, the update SBFD mode indication can be a dynamic SBFD update received via downlink control information (DCI) or media access control (MAC) control element (CE) (MAC-CE) (such as a dedicated DCI or dedicated MAC-CE for transmitting dynamic SBFD updates). The reference SCS for the SBFD mode can be defined separately, for example, in a radio resource control (RRC) message. In some aspects, network node 110 can configure a first value that is less than or equal to the value of any SCS of the configured BWP of the serving cell to which the update is applied. Additionally, network node 110 can configure a second value that is less than or equal to the SCS of the serving cell to which the UE monitors dynamic SBFD updates. UE 120 can identify the update time-domain granularity and / or update frequency-domain granularity of SBFD resources according to the update SBFD mode indication, and UE 120 and network node 110 can communicate via SBFD resources according to the update time-domain granularity and / or update frequency-domain granularity.
