[0002] This patent application claims priority to U.S. Patent Application No. 18 / 296,129, filed April 5, 2023, entitled “Guard Periods or Gaps Between Symbols or Slots or Within a Slot”, 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 protection periods or gaps between or within symbols or time slots. 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 an enhanced set of 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. UEs may communicate with network nodes via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, and "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 an enhancement set 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

[0028] Network nodes with Subband Full-Duplex (SBFD) capability can be configured with coexisting SBFD symbols / slots (symbols or slots) and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. When switching between SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots, the network node and / or UE may require guard periods / gap (guard periods or gaps) between SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. Guard periods / gap allow the network node and / or UE to retune certain radio frequency (RF) / baseband blocks or filters. Guard periods / gap enable adjusted uplink UE timing advance (TA) to align the network node's downlink and uplink timing with the TA offset used for SBFD slots (e.g., TA offset 0) (e.g., adjusted uplink UE TA for SBFD slot inter-UE cross-link interference (CLI) mitigation). Guard intervals / gap allow the UE to perform downlink-to-uplink handover, enabling the UE to switch RF when uplink timing is advanced to the downlink direction. Guard intervals / gap ensure that inter-cell interference (in the downlink direction) from other cells is avoided at the network node before the uplink direction. Guard intervals / gap allow the network node to adapt to different antenna configurations, such as antenna elements or transceiver units (TXRUs) for SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots.

[0029] In some cases, the UE and / or network node may not be configured for guard periods / gap between symbols / slots. For example, the UE and / or network node may not be configured for guard periods / gap between SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. The UE and / or network node may not be configured with permitted type switching boundaries and guard gap / time period location rules. Therefore, the UE and / or network node may be unable to perform RF retuning, TA adjustment, downlink-to-uplink direction switching, and / or adapt different antenna configurations between different symbols / slots, which may degrade the performance of the UE and / or network node.

[0030] In some aspects described herein, a UE or network node may perform first communication in a first type of symbol / time slot. A UE or network node may perform second communication in a second type of symbol / time slot. The first type of symbol / time slot may be an SBFD symbol / time slot, and the second type of symbol / time slot may be a non-SBFD downlink, uplink, or flexible symbol / time slot. Alternatively, the first type of symbol / time slot may be a non-SBFD downlink, uplink, or flexible symbol / time slot, and the second type of symbol / time slot may be an SBFD symbol / time slot. A guard period / gap may be defined between the first type of symbol / time slot and the second type of symbol / time slot, or the guard period / gap may be defined within a time slot corresponding to either the first type of symbol / time slot or the second type of symbol / time slot. The guard period / gap may be defined at least in part based on a reference symbol type switching boundary and the guard period or gap location. In other words, the guard period / gap may be defined at least in part based on permissible type switching boundaries and guard gap / time slot location rules. Therefore, UEs and / or network nodes can use guard periods / slots to perform RF retuning, adjust TA, perform downlink-to-uplink direction switching and / or adapt different antenna configurations between different symbols / slots, which can improve the performance of UEs and / or network nodes.

[0031] 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 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 understand that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently of or in combination with any other aspect of the 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, functions, or structures and functions other than or different from the aspects of the disclosure herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0032] Several aspects of a telecommunications system will now be presented with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, algorithms, etc. (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. Wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., LTE) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., LTE) network, etc. 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 to 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 to 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] 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, 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 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).

[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, drones, remote devices, sensors, meters, 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 generally (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is generally (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. Furthermore, 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 if 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 if 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, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may perform first communication in a first type of symbol / time slot and second communication in a second type of symbol / time slot, wherein a protection period or gap is defined between the first type of symbol / time slot and the second type of symbol / time slot, or the protection period or gap is defined within a time slot corresponding to either the first type of symbol / time slot or the second type of symbol / time slot, and the protection period or gap is defined at least in part based on a reference symbol type switching boundary and the location of the protection period or gap. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0049] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may perform first communication in a first type of symbol / time slot and second communication in a second type of symbol / time slot, wherein a protection period or gap is defined between the first type of symbol / time slot and the second type of symbol / time slot, or the protection period or gap is defined within a time slot corresponding to the first type of symbol / time slot or the second type of symbol / time slot, and the protection period or gap is defined at least in part based on a reference symbol type switching boundary and the location of the protection period or gap. Additionally or alternatively, the 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 the present 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, an array 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 an array of received signals (e.g., R received signals) to an array 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, down-convert, 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), sets of coplanar antenna elements, sets 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 the process).

[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. 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 7 to 15 ( ) aspects of any 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 7 to 15 ( ) aspects of any 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 protection periods or gaps between or within symbols / slots, 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 12 Process 1200 Figure 13 The operation of process 1300 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 12 Process 1200 Figure 13 The operation of process 1300 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.

[0059] In some aspects, the UE (e.g., UE 120) includes: components for performing first communication in a first type of symbol / time slot; and / or components for performing second communication in a second type of symbol / time slot, wherein a guard period or gap is defined between the first type of symbol / time slot and the second type of symbol / time slot, or the guard period or gap is defined within a time slot corresponding to the first type of symbol / time slot or the second type of symbol / time slot, and the guard period or gap is defined at least in part based on a reference symbol type switching boundary and the location of the guard period or gap. 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.

[0060] In some aspects, a network node (e.g., network node 110) includes: components for performing first communication in a first type of symbol / time slot; and / or components for performing second communication in a second type of symbol / time slot, wherein a guard period or gap is defined between the first type of symbol / time slot and the second type of symbol / time slot, or the guard period or gap is defined within a time slot corresponding to the first type of symbol / time slot or the second type of symbol / time slot, and the guard period or gap is defined at least in part based on a reference symbol type switching boundary and the location of the guard period or gap. Components for the network node to perform the operations described herein may include, for example, one or more of the following: 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] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above for these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described for transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0062] 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.

[0063] Communication systems (such as 5G NR systems) can be deployed in various ways with a variety of 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 aggregated or decomposed architectures. For example, base stations (such as Node B (NB), evolved NB (eNB), NR base stations, 5G NB, access points (APs), TRPs, or cells, etc.) or one or more units (or components) performing base station functions can be implemented as aggregated base stations (also known as standalone base stations or monolithic base stations) or decomposed base stations. 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).

[0064] 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 can 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.

[0065] Base station type operation or network design can take into account the aggregation characteristics of base station functions. 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 functions into one or more units that can be deployed independently. Decomposed base stations can include functions implemented by two or more units across various physical locations, as well as functions virtually implemented for at least one unit, which enables flexibility in network design. The various units of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[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 RF access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0067] Each unit in the clusters (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 cluster, 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 clusters via transmission media. In some examples, each unit in the cluster 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 units in other clusters, 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 units in other clusters, 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 can be logically divided 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.

[0069] Each DU 330 may correspond to a logic unit including 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, the Media 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. 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. 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.

[0070] Each RU 340 can implement low-level functions. 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 low-level 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 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 a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (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 can 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 enabling non-real-time control and optimization of RAN elements and resources, including 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 (e.g., via an A1 interface). The near-RT RIC 325 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via an interface (e.g., 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.

[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 modulate 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] Full-duplex operation can involve in-band full-duplex (IBFD) operation, where transmission and reception can occur on the same time and frequency resources. Based at least in part on full or partial overlap, the downlink and uplink directions can share the same IBDF time / frequency resources. Alternatively, full-duplex operation can involve SBFD operation (or flexible duplex), where transmission and reception can occur simultaneously but on different frequency resources. Downlink resources can be separated from uplink resources in the frequency domain. In SBFD operation, downlink and uplink frequency overlap may not occur.

[0076] Figure 4 This is a diagram illustrating example 400 of full-duplex communication according to this disclosure.

[0077] As shown by reference numeral 402, downlink resource 404 and uplink resource 406 may share the same IBDF time / frequency resource, at least partially based on complete overlap. As shown by reference numeral 408, downlink resource 410 and uplink resource 412 may share the same IBDF time / frequency resource, at least partially based on partial overlap. As shown by reference numeral 414, downlink resource 416 and uplink resource 420 may be associated with the same time but different frequencies. Downlink resource 416 and uplink resource 420 may be separated by a guard band 418.

[0078] 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.

[0079] Figure 5This is a diagram illustrating example 500 of full-duplex communication according to this disclosure.

[0080] As shown by reference numeral 502 in the attached figure, a full-duplex network node (e.g., network node 110a) can communicate with a half-duplex UE. The full-duplex network node may experience cross-link interference from another full-duplex network node (e.g., network node 110d). This cross-link interference from another full-duplex network node can be inter-node cross-link interference. The full-duplex network node may experience self-interference. The full-duplex network node can receive uplink transmissions from a first half-duplex UE (e.g., UE 120a) and can send downlink transmissions to a second half-duplex UE (e.g., UE 120e). The full-duplex network node can receive uplink transmissions and send downlink transmissions in the same time slot (e.g., simultaneous receive / send). The second half-duplex UE may experience cross-link interference from the first half-duplex UE (e.g., inter-UE cross-link interference).

[0081] As shown by reference numeral 504 in the attached figure, a full-duplex network node (e.g., network node 110a) can communicate with a full-duplex UE. The full-duplex network node may experience cross-link interference from another full-duplex network node (e.g., network node 110d). The full-duplex network node may experience self-interference. The full-duplex network node can send downlink transmissions to a first full-duplex UE (e.g., UE 120a), and the full-duplex network node can receive uplink transmissions from the first full-duplex UE while simultaneously sending downlink transmissions. The full-duplex network node can send downlink transmissions to a second full-duplex UE (e.g., UE 120e). The second half-duplex UE may experience cross-link interference from the first half-duplex UE. The first UE may experience self-interference.

[0082] As shown by reference numeral 506 in the attached figure, a first full-duplex network node (e.g., network node 110a) that can be associated with multiple TRPs can communicate with the SBFD UE. The first full-duplex network node may be subject to cross-link interference from a second full-duplex network node (e.g., network node 110s). The first full-duplex network node can receive uplink transmissions from a first SBFD UE (e.g., UE120a). The second full-duplex network node can send downlink transmissions to both the first SBFD UE and the second SBFD UE (e.g., UE120e). The second SBFD UE may be subject to cross-link interference from the first SBFD UE. The first SBFD UE may experience self-interference.

[0083] As shown by reference numeral 508 in the attached figure, the SBFD time slot can be associated with non-overlapping uplink / downlink subbands. The SBFD time slot can be associated with simultaneous downlink / uplink transmission / reception on a subband basis. Within the component carrier bandwidth, uplink resource 512 can be located in the frequency domain between the first downlink resource 510 and the second downlink resource 514. The first downlink resource 510, the second downlink resource 514, and the uplink resource 512 can all be associated with the same time.

[0084] SBFD operation can be associated with Time Division Duplex (TDD) or In-Band Carrier Aggregation (CA). SBFD operation can increase the uplink duty cycle, which can lead to reduced latency (e.g., uplink signals can be transmitted in downlink-only slots, or downlink signals can be received in uplink-only slots, resulting in latency savings) and improved uplink coverage. SBFD operation can improve system capacity, resource utilization, and / or spectral efficiency. SBFD operation can robustly enable flexible and dynamic uplink / downlink resource adaptation based on uplink / downlink traffic.

[0085] 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.

[0086] Network nodes with SBFD capability can be configured with coexisting SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. When switching between SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots, the network node and / or UE may require guard periods / gapes between SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. Guard periods / gapes allow the network node and / or UE to retune certain RF / baseband blocks or filters. Guard periods / gapes enable adjusted uplink UE TAs for aligning the network node's downlink and uplink timings with the TA offset used for SBFD slots (e.g., TA offset 0) (e.g., adjusted uplink UE TA for SBFD slots with UE-to-UE CLI mitigation). Guard periods / gapes enable UEs to perform downlink-to-uplink direction handovers, allowing UEs to switch RFs when uplink timings are advanced to the downlink direction. Guard intervals / gap ensure that inter-cell interference from other cells (in the downlink direction) is avoided at the network node before the uplink direction. Guard intervals / gap allow the network node to adapt to different antenna configurations, such as antenna elements or TXRUs for SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots.

[0087] Figure 6 This is a diagram illustrating example 600 of the protection period / gap between symbols / time slots according to this disclosure.

[0088] As shown by reference numeral 602 in the attached figure, the first time slot / symbol can be a downlink time slot / symbol. The second time slot / symbol can be an SBFD time slot / symbol. The second time slot / symbol can be associated with a first downlink subband. The second time slot / symbol can be associated with an uplink subband. The second time slot / symbol can be associated with a second downlink subband. The first time slot / symbol and the second time slot / symbol may need to be separated by a guard period / gap, which provides time for performing RF retuning, adjusting TA, performing downlink-to-uplink direction switching, or adapting to different antenna configurations.

[0089] As shown by reference numeral 604 in the attached figure, the first time slot / symbol can be an SBFD time slot / symbol. The first time slot / symbol can be associated with a first downlink subband. The first time slot / symbol can be associated with an uplink subband. The first time slot / symbol can be associated with a second downlink subband. The second time slot / symbol can be an uplink time slot / symbol. The first and second time slots / symbols may need to be separated by a guard period / gap, which provides time for performing RF retuning, TA adjustment, downlink-to-uplink direction switching, or adapting to different antenna configurations.

[0090] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0091] In some cases, the UE and / or network node may not be configured for guard periods / gap between symbols / slots. For example, the UE and / or network node may not be configured for guard periods / gap between SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. The UE and / or network node may not be configured with permitted type switching boundaries and guard gap / time period location rules. Therefore, the UE and / or network node may be unable to perform RF retuning, TA adjustment, downlink-to-uplink direction switching, and / or adapt different antenna configurations between different symbols / slots, which may degrade the performance of the UE and / or network node.

[0092] In various aspects of the technologies and apparatus described herein, a UE or network node may perform first communication in a first type of symbol / time slot. A UE or network node may perform second communication in a second type of symbol / time slot. The first type of symbol / time slot may be an SBFD symbol / time slot, and the second type of symbol / time slot may be a non-SBFD downlink, uplink, or flexible symbol / time slot. Alternatively, the first type of symbol / time slot may be a non-SBFD downlink, uplink, or flexible symbol / time slot, and the second type of symbol / time slot may be an SBFD symbol / time slot. A guard period / gap may be defined between the first type of symbol / time slot and the second type of symbol / time slot, or the guard period / gap may be defined within a time slot corresponding to either the first type of symbol / time slot or the second type of symbol / time slot. The guard period / gap may be defined at least in part based on a reference symbol type switching boundary and the guard period or gap location. In other words, the guard period / gap may be defined at least in part based on permissible type switching boundaries and guard gap / time slot location rules. Therefore, UEs and / or network nodes can use guard periods / slots to perform RF retuning, adjust TA, perform downlink-to-uplink direction switching and / or adapt different antenna configurations between different symbols / slots, which can improve the performance of UEs and / or network nodes.

[0093] Figure 7 This is a diagram illustrating example 700 related to protection periods or gaps between or within symbols / time slots. (See example 700.) Figure 7 As shown, Example 700 includes communication between a UE (e.g., UE 120) and a network node (e.g., network node 110). In some aspects, the UE and the network node may be included in a wireless network (such as wireless network 100).

[0094] As shown by reference numeral 702 in the attached figure, the UE and / or network node may perform the first communication in a first type of symbol / time slot. The first type of symbol / time slot may be an SBFD symbol / time slot. Alternatively, the first type of symbol / time slot may be a non-SBFD downlink, uplink, or flexible symbol / time slot. The first communication may be a downlink transmission or an uplink transmission.

[0095] As shown by reference numeral 704 in the attached figure, the UE and / or network node may perform second communication in a second type of symbol / time slot. The second type of symbol / time slot may be a non-SBFD downlink, uplink, or flexible symbol / time slot. Alternatively, the first type of symbol / time slot may be an SBFD symbol / time slot. The second communication may be a downlink transmission or an uplink transmission. The second communication may be of the same type as the first communication, or alternatively, the second communication may be of a different type than the first communication. The first type of symbol / time slot and the second type of symbol / time slot may form two types of symbol / time slots, and one downlink or uplink timing may occur on both types of symbol / time slots, or two different downlink or uplink timings may occur on both types of symbol / time slots.

[0096] In some respects, the protection period / gap may be defined between a first type of symbol / time slot and a second type of symbol / time slot, or the protection period / gap may be defined within a time slot corresponding to either the first type of symbol / time slot or the second type of symbol / time slot. The protection period / gap may be defined at least in part based on the reference symbol type switching boundary and the location of the protection period or gap.

[0097] In some respects, at least in part based on implicit rules of protection periods / gap, the reference symbol type switching boundary may correspond to the slot boundary of either the first type of symbol / slot or the second type of symbol / slot. The protection period / gap location may be defined as starting at the end of the reference symbol type switching boundary (e.g., as...). Figure 9 As shown). The protection period / gap position can be defined to end at the start position of the reference symbol type switching boundary (e.g., as shown). Figure 10 As shown). The protection period / gap location can define the protection period / gap switching boundary across reference symbol type (e.g., as shown). Figure 10 (As shown). The protection period / gap location can be defined within the SBFD time slot or in a non-SBFD time slot.

[0098] In some respects, depending on the symbol type combination, the protection period / gap position can be defined as starting at the end of the reference symbol type switching boundary, or ending at the beginning of the reference symbol type switching boundary. At least in part, based on the symbol type combination corresponding to an SBFD symbol followed by a non-SBFD symbol, the protection period / gap position can be defined as starting at the end of the reference symbol type switching boundary. At least in part, based on the symbol type combination corresponding to a non-SBFD symbol followed by an SBFD symbol, the protection period / gap position can be defined as ending at the beginning of the reference symbol type switching boundary.

[0099] In some respects, at least in part based on the correspondence between reference symbol type switching boundaries and slot boundaries, the gap duration associated with the guard period / gap can be predefined in the specification or can be indicated by the network node at least in part based on UE capabilities. In some respects, the guard period / gap can be associated with a UE common time mode or a UE-specific time mode. At least in part based on the correspondence between reference symbol type switching boundaries and slot boundaries, the guard period / gap can be defined based on the number of symbols / slots or milliseconds depending on the subcarrier spacing (SCS).

[0100] In some respects, at least in part based on explicit signaling from network nodes, the reference symbol type switching boundary may correspond to the slot boundary of a first type of symbol / slot or the slot boundary of a second type of symbol / slot. Explicit signaling may indicate a periodic SBFD time pattern or a semi-persistent SBFD time pattern. A periodic or semi-persistent SBFD time pattern may indicate whether a symbol / slot is a gap symbol / slot. Explicit signaling may indicate the protection period / gap location in an aperiodic mode. Explicit signaling may indicate the starting symbol position of the protection period / gap, the length of the protection period / gap, the starting symbol position of the time window, and / or a bitmap of symbols used within the time window of the protection period / gap.

[0101] In some respects, reference symbol type switching boundaries can be within time slots. Protection periods / gap can be represented by the number of symbols less than the duration of a time slot (e.g., as...). Figure 11 (As shown). The start and end times of the protection period / gap can be within any symbolic boundary of the time slot. The protection period / gap can be represented by the number of time slots longer than the time slot duration. The start and end times of the protection period / gap can correspond to the time slot boundaries.

[0102] In some respects, at least in part based on implicit rules of protection periods / gap, the reference symbol type switching boundary can be within a time slot. The protection period / gap position can be defined as starting in the first time slot after the end position of the reference symbol type switching boundary. The protection period / gap position can also be defined as ending at the end position of the last time slot before the start position of the reference symbol type switching boundary. Depending on the symbol type combination, the protection period / gap position can be defined as starting in the first time slot after the end position of the reference symbol type switching boundary, or ending at the end position of the last time slot before the start position of the reference symbol type switching boundary.

[0103] In some respects, at least in part based on the reference symbol type switching boundary within the time slot, the interval duration associated with the guard period / gap can be predefined in the specification, or it can be indicated by the network node at least in part based on UE capabilities. The guard period / gap can be associated with either the UE common time mode or the UE dedicated time mode. At least in part based on the reference symbol type switching boundary within the time slot, the guard period / gap can be defined based on the number of symbols / time slots or the number of milliseconds depending on the SCS.

[0104] In some respects, at least in part, reference symbol type switching boundaries can be within time slots, based on explicit signaling from network nodes. Explicit signaling can indicate a Time Slot Format Indicator (SFI) or TDD time slot format mode with a time slot format as a time slot gap, and can indicate the corresponding time slot format index for each time slot within a time slot period. Explicit signaling can indicate the location of protection periods / gap in an aperiodic pattern. Explicit signaling can indicate the starting symbol position of a protection period / gap, the length of the protection period / gap, the starting symbol position of the time window, and / or a bitmap of symbols used within the time window of the protection period / gap.

[0105] In some respects, the protection period / gap can be defined in the specification, indicated by the network node, or requested by the UE. The protection period / gap can be the number of symbols or time slots, or the number of microseconds or milliseconds. Depending on the two types of symbols or time slots and the switching of the transmit-receive direction, the protection period / gap can be a common value or associated with different values. The UE can be an SBFD-aware UE and is not expected to perform communication during the protection period / gap.

[0106] 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.

[0107] In some respects, a guard gap / period may not be defined between SBFD symbols / slots (or microslots) and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. In this case, the permissible SBFD symbol / slot type and non-SBFD / legacy downlink, uplink, or flexible symbol / slot type switching boundary can be, in a first option, a permissible type switching boundary only at slot boundaries, or, in a second option, a permissible type switching boundary within a slot. In other words, the switching boundary can be at a slot boundary or within a slot.

[0108] Figure 8 This is an example 800 illustrating the association of a protection period or gap between or within a symbol / time slot.

[0109] As shown by reference numeral 802 in the attached figure, the first time slot can be an SBFD time slot. The first time slot can be associated with a first downlink subband, an uplink subband, and a second downlink subband. The second time slot can be a downlink time slot. Permissible type switching boundaries can occur at the time slot boundaries relative to the first and second time slots (e.g., only at time slot boundaries). For example, a permissible type switching boundary can occur at the boundary associated with the second time slot. In this example, a guard gap / period may not occur between the first and second time slots.

[0110] As indicated by reference numeral 804 in the attached figure, a time slot may include non-SBFD / legacy downlink symbols. The time slot may also include SBFD symbols, which may be associated with a first downlink subband, an uplink subband, and a second downlink subband. Permissible type switching boundaries may occur within the time slot. For example, permissible type switching boundaries may appear within non-SBFD / legacy downlink symbols. In this example, a guard gap / period may not occur within the time slot.

[0111] 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.

[0112] In some aspects, the protection gap / time period can be defined between SBFD symbols / slots and non-SBFD / legacy downlink, uplink, or flexible symbols / slots. Consecutive symbols of each symbol type (e.g., consecutive uplink / downlink symbols associated with SBFD slots) can be larger than the protection gap / time period (e.g., at least X%), which reduces symbol type switching overhead. In some aspects, a reference symbol type switching boundary can be defined at slot boundaries (e.g., only at slot boundaries). The symbol type can be different on each side of the reference symbol type switching boundary.

[0113] In some respects, when a protection gap / period is defined between an SBFD symbol / slot and a non-SBFD / legacy downlink, uplink, or flexible symbol / slot, the protection gap / period may be based at least in part on implicit rules (e.g., implicit protection period / gap location rules). Protection period / gap location rules may define the protection gap / period to begin at the end of the reference symbol type switching boundary.

[0114] In some aspects, one or more flexible symbols can be used in specific time slots to indicate guard gaps / periods. Flexible symbols can be used for guard gaps / periods, but not for downlink to uplink handover.

[0115] Figure 9 This is an example 900 illustrating the association of a protection period or gap between or within a symbol / time slot.

[0116] like Figure 9 As shown, the first time slot can be an SBFD time slot. The first time slot can be associated with a first downlink subband, an uplink subband, and a second downlink subband. The second time slot can be a downlink time slot. The permissible type switching boundary can be the switching type at the time slot boundary when the protection gap / period begins at the end of the time slot boundary. The time slot boundary can correspond to the end position of the first time slot. As an example, the protection gap / period can be three symbols. The protection gap / period can be defined at least partially based on the time slot boundary.

[0117] As indicated above, Figure 9 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 9 The examples described are different.

[0118] In some respects, protection time / gap location rules can define protection gaps / times to begin at the end of a reference symbol type switching boundary. Protection time / gap location rules can define protection gaps / times to end at the start of a reference symbol type switching boundary. Protection time / gap location rules can define protection gaps / times across reference symbol type switching boundaries (e.g., the end of a large number of all gap symbols). Protection time / gap location rules can define protection gaps / times on SBFD time slots or non-SBFD time slots.

[0119] Figure 10 This is a diagram illustrating example 1000 associated with a protection period or gap between or within a symbol / time slot.

[0120] As shown by reference numeral 1002 in the attached figure, the first time slot can be an SBFD time slot. The first time slot can be associated with a first downlink subband, an uplink subband, and a second downlink subband. The second time slot can be a downlink time slot. The permissible type switching boundary can be the switching type at the time slot boundary when the protection gap / period ends at the start position of the time slot boundary. The time slot boundary can correspond to the start position of the second time slot. As an example, the protection gap / period can be three symbols.

[0121] As shown by reference numeral 1004 in the attached figure, the first time slot can be an SBFD time slot. The first time slot can be associated with a first downlink subband, an uplink subband, and a second downlink subband. The second time slot can be a downlink time slot. The permissible type switching boundary can be the switching type at the time slot boundary in the case of the end of a guard gap / time period across the time slot boundary. The time slot boundary can be between the first and second time slots, such that the time slot boundary can occur one or two symbols after the end position of the first time slot and one or two symbols before the start position of the second time slot.

[0122] As indicated above, Figure 10 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 10 The examples described are different.

[0123] In some respects, whether a protection gap / period begins at the end of the reference symbol type switching boundary or ends at the beginning of the reference symbol type switching boundary may depend on the symbol type combination. When the symbol type combination is SBFD symbols and non-SBFD symbols, the protection gap / period may begin at the end of the reference symbol type switching boundary. When the symbol type combination is both non-SBFD and SBFD symbols, the protection gap / period may end at the beginning of the reference symbol type switching boundary. Non-SBFD symbols may be used in the protection gap / period to prioritize SBFD symbols, or alternatively, SBFD symbols may be used in the protection gap / period to prioritize non-SBFD symbols.

[0124] In some respects, when the reference symbol type switching boundary is defined at a slot boundary, the gap duration associated with the guard gap / period can be predefined in the specification and / or can be indicated to the UE by the network node at least in part based on the UE's capabilities. The gap duration can be used in UE common gap mode and / or UE-specific gap mode. The guard gap / period can be defined according to symbols / slots, which can be SCS-related. The gap duration can depend on the combination of symbol types.

[0125] In some respects, when the reference symbol type switching boundary is defined at the slot boundary, the guard gap / segment can be based at least in part on explicit signaling from the network node to the UE. Explicit signaling can indicate which symbol is a gap symbol. In some respects, in addition to existing symbol types, periodic SBFD or semi-persistent SBFD modes can also indicate whether a symbol is a gap symbol. For example, for two bits, "00" can indicate legacy TDD mode, "01" can indicate SBFD, and "10" can indicate a guard period / gap per symbol or per slot. Periodic SBFD or semi-persistent SBFD modes can be indicated via RRC signaling or via MAC control element (MAC-CE). In some respects, aperiodic modes can indicate the guard period / gap location. One or more guard period / gap opportunities can occur within a time window but may not repeat after the time window. As an example, for a guard period / gap, the gap start symbol position and gap length can be indicated by the network node. As another example, for multiple protection periods / gap in a time window, the window start symbol position and the bitmap of symbols in the time window used for protection periods / gap (e.g., whether a symbol is a protection period / gap symbol) can be indicated by network nodes.

[0126] In some respects, the reference symbol type switching boundary can be within a time slot. Protection periods / gap can be represented by symbols. For example, the start / end time of a protection period / gap can be any symbol boundary. In this case, the start / end time of the protection period / gap may not be associated with a time slot boundary (e.g., any symbol within a time slot can correspond to the start / end time of a protection period / gap).

[0127] Figure 11 This is an example 1100 illustrating the association of protection periods or gaps between or within symbols / time slots.

[0128] like Figure 11 As shown, a time slot may include SBFD symbols, which can be associated with a first downlink subband, an uplink subband, and a second downlink subband. Time slots may also be associated with non-SBFD / legacy uplink symbols. Guard gaps / periods may occur within a time slot. For example, a guard gap / period may span N symbols within a time slot.

[0129] As indicated above, Figure 11 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 11 The examples described are different.

[0130] In some respects, reference symbol type switching boundaries can be within time slots. Protection periods / gap can be represented by time slots. Time slots can be associated with relatively high SCS bands (such as 480kHz or 960kHz SCS). Time slots can be associated with relatively short time slot durations. The start / end times of protection periods / gap can be within time slot boundaries.

[0131] In some aspects, protection periods / gap can be based at least in part on implicit rules (e.g., implicit protection period / gap location rules). A protection period / gap can begin in the first time slot after the end position of the reference symbol type switching boundary, and any remaining symbols preceding the protection period / gap can be discarded. A protection period / gap can begin at the end position of the last time slot before the start position of the reference symbol type switching boundary, and any remaining symbols preceding the protection period / gap can be discarded. Whether a protection period / gap begins in the first time slot after the end position of the reference symbol type switching boundary or at the end position of the last time slot before the start position of the reference symbol type switching boundary depends on the symbol type combination. When the symbol type combination is SBFD symbols and non-SBFD symbols, the protection period / gap can begin in the first time slot after the end position of the reference symbol type switching boundary. When the symbol type combination is both non-SBFD and SBFD symbols, the protection period / gap can begin at the end position of the last time slot before the start position of the reference symbol type switching boundary. Non-SBFD symbols can be used for protection gaps / time periods to prioritize SBFD symbols, or alternatively, SBFD symbols can be used for protection gaps / time periods to prioritize non-SBFD symbols.

[0132] In some respects, when the reference symbol type switching boundary is within a time slot, the gap duration associated with the guard gap / period can be predefined in the specification and / or can be indicated to the UE by the network node at least in part based on the UE's capabilities. The gap duration can be used in UE common gap mode and / or UE-specific gap mode. The guard gap / period can be defined according to symbols / time slots, which can be SCS-related. The gap duration can depend on the combination of symbol types.

[0133] In some aspects, when the reference symbol type switching boundary is within a time slot, the protection gap / period can be based at least in part on explicit signaling from the network node to the UE. In some aspects, in SFI or TDD mode, a time slot format can be added as a gap time slot, and the corresponding time slot format index for each time slot within a time slot period can be indicated by the network node. For example, a reserved time slot format identifier can be used for the gap time slot identifier. As another example, for 100 time slots per period in TDD mode, the network node can indicate the time slot format identifier for each time slot within the time period used for the protection gap / period. In some cases, the gap / slot pattern can be a dedicated pattern and not combined with a TDD pattern (e.g., "1" or "0" for each slot in a time slot period). Periodic or semi-persistent time slot patterns can be indicated via RRC signaling or MAC-CE. In some aspects, aperiodic patterns can be used to indicate the location of protection periods / gap intervals. One or more protection period / gap intervals may occur within a time window but may not repeat after the time window. As an example, for a single protection period / gap, the gap start symbol position and the gap length can be indicated by the network node. As another example, for multiple protection periods / gap intervals within a time window, the window start symbol position and a bitmap of symbols used within the time window for protection periods / gap intervals (e.g., whether a symbol is a protection period / gap symbol) can be indicated by the network node.

[0134] In some respects, guard gaps / periods can be defined in the specification, indicated by the network node, and / or requested by the UE (e.g., a conditional request when the UE requests a gap period longer than the cell common gap period configured by the network node). A guard gap / period can be N symbols / slots or (depending on the SCS to map to N symbols / slots) Kus / ms. Depending on the handover from one type and one transmit / receive (Tx / Rx) direction to another type and the same / different Tx / Rx direction, the guard gap / period can be a common value or a different value. In some cases, SBFD-aware UEs do not expect to transmit or receive during guard gaps / periods.

[0135] Figure 12 This is a diagram illustrating an example procedure 1200 performed by a UE according to this disclosure. Example procedure 1200 is an example in which a UE (e.g., UE 120) performs operations associated with a protection period / gap between or within a symbol / slot.

[0136] like Figure 12 As shown, in some aspects, process 1200 may include performing first communication in a first type of symbol / slot (block 1210). For example, the UE (e.g., using...) Figure 14The depicted communication manager 1406 can perform first communication in a first type of symbol / slot, as described above.

[0137] like Figure 12 Further shown, in some aspects, process 1200 may include performing a second communication in a second type of symbol / slot, where a protection period or gap is defined between a first type of symbol / slot and a second type of symbol / slot, or where the protection period or gap is defined within a slot corresponding to either a first type of symbol / slot or a second type of symbol / slot, and the protection period or gap is defined at least in part based on a reference symbol type switching boundary and the location of the protection period or gap (box 1220). For example, a UE (e.g., using...) Figure 14 The described communication manager 1406 can perform second communication in a second type of symbol / time slot, where the protection period or gap is defined between a first type of symbol / time slot and a second type of symbol / time slot, or the protection period or gap is defined within a time slot corresponding to a first type of symbol / time slot or a second type of symbol / time slot, and the protection period or gap is defined at least in part based on the reference symbol type switching boundary and the location of the protection period or gap, as described above.

[0138] Process 1200 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere in this document.

[0139] In the first aspect, the first type of symbol / time slot is an SBFD symbol / time slot, and the second type of symbol / time slot is a non-SBFD downlink, uplink, or flexible symbol / time slot, or the first type of symbol / time slot is a non-SBFD downlink, uplink, or flexible symbol / time slot, and the second type of symbol / time slot is an SBFD symbol / time slot.

[0140] In the second aspect, either alone or in combination with the first aspect, at least in part based on implicit rules for protecting time slots / gap, the reference symbol type switching boundary corresponds to the slot boundary of the first type of symbol / slot or the second type of symbol / slot.

[0141] In the third aspect, either alone or in combination with one or more of the first and second aspects, the protection period / gap position is defined as starting at the end position of the reference symbol type switching boundary.

[0142] In the fourth aspect, either alone or in combination with one or more of the first to third aspects, the protection period / gap position is defined as ending at the starting position of the reference symbol type switching boundary.

[0143] In the fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the protection period / gap location defines the protection period / gap switching boundary across reference symbol type.

[0144] In the sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the protection period / gap location defines the protection period / gap as being within the SBFD time slot or in a non-SBFD time slot.

[0145] In the seventh aspect, either alone or in combination with one or more of the first to sixth aspects, depending on the symbol type combination, the protection period / gap position is defined as either starting at the end of the reference symbol type switching boundary or ending at the beginning of the reference symbol type switching boundary.

[0146] In the eighth aspect, either alone or in combination with one or more of the first to seventh aspects, the protection period / gap position is defined to begin from the end position of the reference symbol type switching boundary, based at least in part on the correspondence between the symbol type combination and the SBFD symbol followed by a non-SBFD symbol; or the protection period / gap position is defined to end at the start position of the reference symbol type switching boundary, based at least in part on the correspondence between the symbol type combination and the non-SBFD symbol followed by an SBFD symbol.

[0147] In the ninth aspect, either alone or in combination with one or more of the first to eighth aspects, at least in part based on the reference symbol type switching boundary corresponding to the slot boundary, the gap duration associated with the protection period / gap is predefined in the specification or indicated by the network node at least in part based on the UE capability.

[0148] In the tenth aspect, either alone or in combination with one or more of the first to ninth aspects, at least in part, based on the reference symbol type switching boundary corresponding to the slot boundary, the protection period / gap is associated with the UE common time mode or the UE dedicated time mode, and the protection period / gap is defined according to the number of symbols / slots or the number of milliseconds depending on the subcarrier interval.

[0149] In the eleventh aspect, either alone or in combination with one or more of the first to tenth aspects, at least in part based on explicit signaling from network nodes, the reference symbol type switching boundary corresponds to the time slot boundary of the first type of symbol / time slot or the time slot boundary of the second type of symbol / time slot.

[0150] In the twelfth aspect, either alone or in combination with one or more of the first to eleventh aspects, explicit signaling indicates a periodic SBFD time pattern or a semi-persistent SBFD time pattern, and the periodic SBFD time pattern or the semi-persistent SBFD time pattern indicates whether the symbol / slot is a gap symbol / slot.

[0151] In the thirteenth aspect, either alone or in combination with one or more of the first to twelfth aspects, explicit signaling indicates the location of a protection period / gap in an aperiodic mode. The explicit signaling indicates one or more of the following: the position of the protection period / gap start symbol, the length of the protection period / gap, the position of the time window start symbol, or a bitmap of symbols used in the time window of the protection period / gap.

[0152] In the fourteenth aspect, either alone or in combination with one or more of the first to thirteenth aspects, the reference symbol type switching boundary is within the time slot.

[0153] In the fifteenth aspect, alone or in combination with one or more of the first to fourteenth aspects, the protection period / gap is represented by the number of symbols less than the duration of the time slot, and the start time and end time of the protection period / gap are within any symbol boundary of the time slot.

[0154] In the sixteenth aspect, either alone or in combination with one or more of the first to fifteenth aspects, the protection period / gap is expressed as the number of time slots longer than the duration of the time slot, and the start time and end time of the protection period / gap correspond to the time slot boundary.

[0155] In the seventeenth aspect, alone or in combination with one or more of the first to sixteenth aspects, at least in part based on implicit rules for protecting time slots / gap periods, the reference symbol type switching boundary is within the time slot.

[0156] In the eighteenth aspect, alone or in combination with one or more of the first to seventeenth aspects, the protection period / gap position is defined as the protection period / gap starting from the first time slot after the end position of the reference symbol type switching boundary.

[0157] In the nineteenth aspect, either alone or in combination with one or more of the first to eighteenth aspects, the protection period / gap position is defined as ending at the end of the last time slot before the start position of the reference symbol type switching boundary.
