[0002] This Patent Application claims priority to U.S. Patent Application No. 18 / 353,686, filed July 17, 2023, entitled “APPLICATION OF DYNAMIC INDICATION FOR SUBBAND FULL DUPLEX,” and assigned to the assignee hereof. The disclosure of the prior application is considered part of and is hereby incorporated by reference in its entirety into this Patent Application. TECHNICAL FIELD
[0003] Aspects of the present disclosure relate generally to wireless communication, and more specifically to techniques and apparatuses for applying dynamic indication for subband full duplex. BACKGROUND
[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, or transmit power). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).
[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless communication devices to communicate on a municipal, national, regional, and even global level. New Radio (NR), which can be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, CP-OFDM or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and support beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. SUMMARY

[0029] Various aspects generally relate to wireless communication, and more particularly, to full duplex (FD) transmissions. Some aspects more specifically relate to user equipment (UE) operating in an in-band FD mode. In an in-band full duplex mode, a UE can transmit and receive on the same time and frequency resources. The uplink and downlink can share the same time and frequency resources. Full duplex operation can include a sub-band full duplex (SBFD) mode. The SBFD mode can also be referred to as a sub-band frequency division duplex mode or a flexible duplex mode. A wireless communication device can transmit and receive at the same time (in the same SBFD symbol or slot), but the wireless communication device can transmit and receive on different frequency domain resources.
[0030] A UE can use a configured symbol or slot pattern to transmit or receive communications. The configured symbol or slot pattern can include a combination of downlink symbols or slots, uplink symbols or slots, or SBFD symbols or slots within a bandwidth part (BWP) for uplink (UL) and downlink (DL). The configuration can be semi-static. However, traffic and channel conditions can change such that the semi-static configuration is not the optimal choice. In some aspects, the UE can receive a dynamic indication that adds or updates one or more SBFD symbols or slots in the symbol or slot pattern. The UE can apply the dynamic indication by adding or updating one or more SBFD symbols or slots to or from the semi-statically configured symbol or slot pattern. For example, the dynamic indication can add SBFD symbols or slots by converting downlink symbols or slots to SBFD symbols or slots. While the dynamic indication can update the semi-static pattern, there can be cases where the update or addition to the pattern can cause some communications to suffer from a delay due to a transition time needed to switch or retune antennas.
[0031] According to aspects described herein, a UE can be configured with a restriction rule that dictates when and how to apply a dynamic indication to a semi-static time and frequency configuration for SBFD operation. For example, the restriction rule can limit the symbols or slots that can be added or updated (subtracted) for SBFD.
[0032] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by limiting the application of dynamic indications to semi-static configurations involving SBFD, the described techniques can be used to reduce latency caused by antenna transitions.
[0033] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may 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 to make this disclosure thorough and complete, and to 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 practiced using structures, functionalities, or structures and functionalities 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 claims.
[0034] 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 blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.
[0035] 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.
[0036] 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)).
[0037] 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).
[0038] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of network node 110 and / or the network node subsystem serving that coverage area, depending on the context in which the term is used. 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., with 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).
[0039] 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 may include more than one base station.
[0040] 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, or repeater, etc.
[0041] The 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, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in the 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).
[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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 or air interface, etc. A frequency may be referred to as a carrier or 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.
[0046] 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.
[0047] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, or channels based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been designated as frequency 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).
[0048] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used 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. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been identified 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.
[0049] 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.
[0050] In some aspects, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a semi-static time and frequency configuration for SBFD operation in a symbol or slot mode. The communication manager 140 may receive a dynamic indication to add or update one or more SBFD symbols or slots in the symbol or slot mode. The communication manager 140 may communicate based at least in part on one or more of the semi-static time and frequency configuration, and the dynamic indication or a restriction rule limiting the application of the dynamic indication. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0051] In some aspects, a network entity (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send a semi-static time and frequency configuration for SBFD operation in a symbol or slot mode. The communication manager 150 may send a dynamic indication to add or update one or more SBFD symbols or slots in that symbol or slot mode. The communication manager 150 may communicate based at least in part on one or more of the semi-static time and frequency configuration, and the dynamic indication or a restriction rule limiting the application of the dynamic indication. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0052] 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.
[0053] 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.
[0054] 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 allocation 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 signals (CRS) or demodulation reference signals (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).
[0055] 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.
[0056] 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.
[0057] 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 )
[0058] 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. The 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 4 to 12 ( ) any aspect of the methods described in the method.
[0059] 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 for scheduling 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 4 to 12 ( ) any aspect of the methods described in the method.
[0060] The controller / processor of the network entity (e.g., controller / processor 240 of network node 110), controller / processor 280 of UE 120, or Figure 2 Any other component may perform one or more techniques associated with the use of restriction rules when the application involves dynamic indications of SBFD, 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 9 The process 900 Figure 10 The operation of process 1000 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 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, etc.
[0061] In some aspects, the UE (e.g., UE 120) includes: components for: receiving a semi-static time and frequency configuration for SBFD operation in a symbol or slot mode; components for receiving a dynamic indication that adds or updates one or more SBFD symbols or slots in the symbol or slot mode; and / or components for: communicating at least in part based on one or more of the semi-static time and frequency configuration, and the dynamic indication or a restriction rule limiting the application of the dynamic indication. Components for the UE to perform the operations described herein may include, for example, one or more of the following: 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.
[0062] In some aspects, a network entity (e.g., network node 110) includes: components for transmitting a semi-static time and frequency configuration for SBFD operation in a symbol or time slot mode; components for transmitting a dynamic indication that adds or updates one or more SBFD symbols or time slots in the symbol or time slot mode; and / or components for communicating at least in part based on one or more of the semi-static time and frequency configuration, and the dynamic indication or a restriction rule limiting the application of the dynamic indication. In some aspects, components for the network entity to perform the operations described herein may include one or more of, for example, 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.
[0063] 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.
[0064] 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.
[0065] 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.
[0066] Figure 3 This 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.
[0067] Each of these units (including CU 310, DU 330, RU 340) and 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 of these units, or an associated processor or controller providing instructions to one or more communication interfaces of the respective unit, may be configured to communicate with one or more other units via transmission media. In some examples, each unit may include a wired interface and a wireless interface configured to receive signals via a wired transmission media or transmit signals to one or more other units, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals via a wireless transmission media or transmit signals to one or more other units, or both.
[0068] 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 may 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 may be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.
[0069] 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, MAC layer, and one or more high physical (PHY) layers, at least in part, according to functional partitioning such as that 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 CU310.
[0070] Each RU 340 can implement lower-layer functionality. In some deployments, the RU 340 controlled by the DU 330 may 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 at least in part on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UE 120s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may 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.
[0071] 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.
[0072] 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 an E2 interface, through data collection and actions, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.
[0073] 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).
[0074] 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.
[0075] Figure 4 This is a diagram illustrating an example of full-duplex communication 400 according to the present disclosure. In some cases, wireless communication devices (such as UEs or network entities) may support full-duplex operation. Full-duplex operation may include the wireless communication devices transmitting and receiving almost simultaneously.
[0076] The UE can operate in in-band FD mode. In in-band full-duplex mode, the UE can transmit and receive on the same time and frequency resources. The uplink and downlink can share the same time and frequency resources. For example, in the first full-duplex communication 402, the time and frequency resources used for the uplink can completely overlap with those used for the downlink. Similarly, in the second full-duplex communication 404, the time and frequency resources used for the uplink can partially overlap with those used for the downlink.
[0077] Full-duplex operation may include SBFD mode. SBFD mode may also be referred to as sub-band frequency division duplex mode or flexible duplex mode. SBFD communication 406 illustrates that wireless communication devices can transmit and receive simultaneously (within the same SBFD time slot), but the wireless communication devices can transmit and receive on different frequency domain resources. For example, a network entity can operate in SBFD mode. The network entity can schedule a first UE to receive downlink communication in an SBFD time slot. The network entity can schedule a second UE to transmit uplink communication in the same SBFD time slot. However, uplink communication may interfere with the first UE that is receiving downlink communication. To address this issue, the downlink time / frequency resources in the SBFD time slot can be separated from the uplink time / frequency resources in the SBFD time slot by a gap (e.g., in time or frequency), which can be used to reduce self-interference and improve latency and uplink coverage. This gap can be a frequency offset or frequency gap (guard band) between the downlink time / frequency resources and the uplink time / frequency resources in the same SBFD time slot.
[0078] The symbol allows uplink transmission within the uplink subband. The symbol disallows uplink transmission outside the uplink subband. The frequency location of the downlink subband can be known to the SBFD-aware UE. The frequency location of the downlink subband can be explicitly indicated or implicitly derived. The symbol allows downlink reception within the downlink subband. In the symbol, uplink transmission can be within the active uplink BWP, and downlink reception can be within the active downlink BWP.
[0079] Full-duplex and SBFD can increase uplink duty cycle, which reduces latency and improves coverage. SBFD can enhance system capabilities, resource utilization, and / or spectrum efficiency. SBFD enables flexible and dynamic uplink / downlink resource adaptation for services in a robust manner.
[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 a slotted pattern with SBFD slots according to the present disclosure.
[0082] The UE can use configured symbol or time slot patterns to send or receive communications. Configured symbol or time slot patterns can include combinations of: downlink symbols or time slots, uplink symbols or time slots, or SBFD symbols or time slots within a BWP for UL and DL. Example 500 illustrates SBFD time slots (SBFD symbols within SBFD time slots) that can be used for operation in an RRC connected state, in which the UE maintains a connection established using RRC signaling. In some examples, the UE can be an SBFD-aware UE, where the time and frequency positions of the subbands used for SBFD operation are known to the SBFD-aware UE. In some examples, the UE can receive a semi-static time and frequency SBFD configuration for the symbol or time slot pattern. The symbol or time slot pattern can be repeated. The UE can receive this configuration via RRC signaling. This configuration can be semi-static because the UE maintains this configuration for communication until the UE receives an updated configuration.
[0083] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.
[0084] Figure 6 These are illustrations of examples 600, 602, and 604 of a dynamic SBFD according to this disclosure.
[0085] The UE can be configured with a semi-static configuration. However, service and channel conditions may change, making a semi-static configuration less optimal. In some aspects, the UE may receive a dynamic indication that adds or updates one or more SBFD symbols or time slots in a symbol or time slot pattern. The UE can apply this dynamic indication. Applying the dynamic indication may include adding or updating one or more SBFD symbols or time slots to the symbol or time slot pattern of the semi-static configuration. For example, the dynamic indication may add SBFD symbols or time slots by converting downlink symbols or time slots to SBFD symbols or time slots. In this way, the uplink band can allow uplink communication faster or allow more uplink communication faster, instead of waiting for the next uplink symbol or time slot. In another example, the dynamic indication may update the SBFD symbol or time slot by converting SBFD symbols or time slots to downlink symbols or time slots or uplink symbols or time slots. In this way, uplink or downlink communication can be increased or decreased. This can reduce latency and increase throughput.
[0086] Example 600 illustrates an application of a dynamic indicator for updating (subtracting) an SBFD slot with two downlink subbands and one uplink subband. This dynamic indicator identifies the SBFD slot in the slot pattern (e.g., by slot index) and indicates that the SBFD slot will become a downlink slot (or a flexible slot). Example 602 illustrates an application of a dynamic indicator for updating an SBFD slot with two flexible subbands and one uplink subband. This dynamic indicator identifies the SBFD slot and indicates that the SBFD slot will become an uplink slot. Example 604 illustrates an application of a dynamic indicator that adds an SBFD slot by converting a flexible slot to an SBFD slot with two downlink subbands and one uplink subband.
[0087] In some aspects, dynamic indications for adding SBFD symbols or time slots can be included in the scheduling downlink control information (DCI), which schedules communication and is used to indicate whether a resource block (RB) in a flexible subband is used for uplink or downlink transmission. In some aspects, the scheduling DCI for adding SBFD symbols or time slots can be used to determine whether downlink reception outside a semi-statically configured downlink subband and / or uplink transmission outside a semi-statically configured uplink subband is permitted. In some aspects, unscheduled DCIs (which do not schedule data or are group common DCIs) can indicate whether a symbol or time slot is an SBFD symbol or time slot. In some aspects, dynamic indications can include a slot format indicator (SFI). For example, a downlink symbol or time slot in an SFI can update an SBFD symbol or time slot to a downlink symbol or time slot. An uplink symbol or time slot in an SFI can update an SBFD symbol or time slot to an uplink symbol or time slot. In some aspects, dynamic indications in a Media Access Control (MAC) control element (MAC CE) can indicate whether a symbol or time slot is an SBFD symbol or time slot.
[0088] While dynamic indications can be updated to include semi-static time and frequency patterns for SBFD symbols or time slots, there are potential issues: updating or adding patterns may cause some communication to be delayed due to the switching time required for antenna switching or retuning. Other dynamic indications may delay certain signals, such as Synchronization Block (SSB) symbols, Tracking Reference (TRS) symbols, Aperiodic Channel State Information (CSI) Reference (A-CSI-RS) symbols, Control Resource Set (CORESET) symbols, Semi-Persistent Scheduling (SPS) symbols, Beam Failure Detection (BFD) symbols, or Radio Link Management (RLM) symbols. Applying dynamic indications at inappropriate times can lead to increased latency and / or reduced throughput.
[0089] As indicated above, Figure 6This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.
[0090] Figure 7 This is a diagram illustrating example 700 associated with the restriction rules for using dynamic indicators according to this disclosure. For example... Figure 7 As shown, network entities (e.g., network node 110) and UE 720 (e.g., UE 120) can communicate with each other via a wireless network (e.g., wireless network 100).
[0091] Based on the aspects described herein, the UE can be configured with limiting rules that specify when and how dynamic indications are applied to the semi-static time and frequency configuration of SBFD operation. For example, limiting rules can restrict the addition or updating (subtraction) of symbols or time slots in the SBFD. By limiting the application of dynamic indications, the UE can reduce the latency caused by excessively frequent switching or retuning of antennas during and from SBFD time slots, or reduce the latency caused by delaying certain signaling.
[0092] Example 700 illustrates the use of restrictive rules for applying dynamic indications in a symbol or slot mode configured with one or more SBFD symbols or slots. As indicated by reference numeral 725, network entity 710 may send a semi-static time and frequency configuration for SBFD operation. This configuration may indicate the frequency bands in the SBFD slots used for uplink or downlink. This configuration may indicate which symbols or slots are SBFD symbols or slots, which are downlink symbols or slots, which are uplink symbols or slots, and which are flexible symbols or slots. SBFD operation may be available to network entity 710 if UE 720 is operating in half-duplex mode, or to both network entity 710 and UE 720 if UE 720 is also operating in full-duplex mode (capable of SBFD). UE 720 can be semi-statically configured with uplink subbands as SBFD symbols or slots on a traditional downlink, or as flexible symbols or slots in a Time Division Duplex (TDD) uplink / downlink common configuration (e.g., TDD-UL-DL-ConfigCommon). As shown by reference numeral 730, network entity 710 and UE 720 can communicate (transmit or receive communications) at least in part based on this semi-static configuration (symbol or slot mode).
[0093] As indicated by reference numeral 735, network entity 710 may send a dynamic indication. This dynamic indication may be included in a scheduled DCI, an unscheduled DCI, a group common DCI, or a MAC CE. As indicated by reference numeral 740, network entity 710 and UE 720 may communicate at least partially based on this semi-static configuration and the dynamic indication. UE 720 may apply the dynamic indication to change one or more symbols or time slots in a symbol or time slot pattern. This change may involve adding or updating (subtracting) one or more SBFD symbols or time slots in a symbol or time slot pattern configured by the semi-static configuration. For example, the dynamic indication may update the SBFD symbol or time slot by changing it to a downlink symbol or time slot (having one uplink subband and at least one downlink subband). The dynamic indication may update the SBFD symbol or time slot by changing it to a flexible symbol or time slot, a downlink symbol or time slot, or an uplink symbol or time slot. Dynamic indication can be achieved by adding SBFD symbols or slots by changing downlink symbols or slots, uplink symbols or slots, or flexible symbols or slots to SBFD symbols or slots (with one uplink subband and at least one downlink subband).
[0094] As also indicated by reference numeral 740, UE 720 may further communicate based at least in part on restriction rules for applications subject to restriction dynamic indication. Network entity 710 may communicate based at least in part on restriction rules followed by UE 720. Network entity 710 may send restriction rules to UE 720, or UE 720 may obtain restriction rules from stored configuration information (specified by the standard).
[0095] Restriction rules can limit the application of dynamic indications to specific symbol or slot types. In some aspects, restriction rules can specify that one or more SBFD symbols or slots can be added to or updated to downlink symbols or slots and flexible symbols or slots. UE 720 can expect network entity 710 to dynamically add or subtract SBFD symbols or slots that are semi-statically configured on downlink symbols or slots or flexible symbols or slots.
[0096] In some respects, limiting rules can specify that one or more SBFD symbols or slots can be added to or updated to flexible symbols or slots, but cannot be added to or updated to downlink symbols or slots. UE 720 may not expect network entity 710 to dynamically add or remove SBFD symbols or slots configured on downlink symbols or slots. Downlink symbols or slots can be static and protected from inter-UE cross-link interference (CLI). Limiting rules can also improve downlink throughput because they prevent downlink slots from being converted to SBFD slots. Limiting rules can help maintain Quality of Service (QoS).
[0097] In some respects, restriction rules can allow the reception of certain signaling that might otherwise be delayed due to dynamic indication. For example, a restriction rule can specify that one or more SBFD symbols or slots can be added to or updated as flexible symbols or slots, and designated as unrestricted downlink symbols or slots. Restricted downlink symbols or slots may include symbols or slots carrying SSB symbols, TRS symbols, A-CSI-RS symbols, CORESET symbols, SPS symbols, BFD symbols, RLM symbols, and / or other control or priority signaling. Unrestricted downlink symbols or slots may be symbols or slots that do not carry such signaling. UE 720 may not expect network entity 710 to dynamically add SBFD symbols or slots to semi-statically configured restricted downlink symbols or slots.
[0098] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The examples described are different.
[0099] Figure 8 These are illustrations of examples 800 and 802 of the restriction rules for symbols or time slot regions according to this disclosure.
[0100] Example 800 illustrates an SBFD region 804 comprising multiple consecutive SBFD slots 806, 808, 810, and 812. Slots 806 and 812 are edge slots because they are located at the edges or boundaries of the SBFD region 804. Slots 808 and 810 are non-edge slots; they are not contiguous with other slots, such as downlink or uplink slots. Non-edge slots can be considered intermediate slots.
[0101] In some respects, the restriction rules can limit updates or additions to edge time slots within a symbol or time slot region. If a non-edge time slot is updated, the UE 720 can be expected to retune its antenna multiple times in that region, which may result in latency. By restricting updates to edge time slots, the UE 720 avoids performing multiple antenna switching operations within the same region.
[0102] Example 800 illustrates a restriction rule that prevents SBFD slot 808 from being converted (updated) to a downlink slot (or uplink or flexible slot) in the middle of SBFD area 804. This restriction rule helps improve uplink coverage because UE 720 may not expect network entity 170 to dynamically remove SBFD symbols or slots in the middle of SBFD area 804, thus avoiding adding more conversion points between SBFD symbols or slots and non-SBFD symbols or slots. Conversion points can reduce uplink coverage and increase overhead.
[0103] In some respects, UE 720 may also not expect network entity 710 to dynamically add SBFD symbols on restricted downlink symbols within a downlink symbol or slot area (consisting of multiple consecutive downlink symbols or slots). The restriction rule can also restrict the addition of SBFD symbols or slots to a flexible area (consisting of multiple consecutive flexible symbols or slots) or an uplink area (consisting of multiple consecutive uplink slots). Example 802 illustrates a restriction rule that prevents symbols or slots in downlink area 814 (or a flexible area or uplink area) from being converted to SBFD symbols or slots. This restriction rule can also prevent non-edge slots in SBFD area 816 from being updated to another type of slot, such as a downlink slot. By restricting transition points, the restriction rule can help improve throughput by not wasting transmit / receive time on additional transitions.
[0104] As indicated above, Figure 8 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 8 The examples described are different.
