[0002] This Patent Application claims priority to U.S. Provisional Patent Application No. 63 / 497,577, filed April 21, 2023, entitled “DIRECTIONAL COLLISION HANDLING FOR NON-CELL-DEFINING SYNCHRONIZATION SIGNAL BLOCK,” and U.S. Non-Provisional Patent Application No. 18 / 618,768, filed March 27, 2024, entitled “DIRECTIONAL COLLISION HANDLING FOR NON-CELL-DEFINING SYNCHRONIZATION SIGNAL BLOCK,” which are hereby expressly incorporated by reference herein. TECHNICAL FIELD

[0003] Aspects of the present disclosure relate generally to wireless communication, and more specifically to techniques and apparatuses for directional collision handling for non-cell-defining synchronization signal and physical broadcast channel block communications. 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 and 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 (3 GPP).

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols to enable different user equipment (UEs) to communicate on the same physical frequency channel. New Radio (NR), which can be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 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 OFDM with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP- OFDM or discrete Fourier transform spread OFDM (DFT-s-OFDM) on the uplink (UL), as well as supporting beamforming, multiple -input multiple-output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE, NR, and other radio access technologies.

[0006] Signals transmitted by network components can sometimes interfere with signals transmitted by other network components. For example, a signal intended for one network device can be received by a different network device. As another example, interference can occur when a network device receives a signal at an unexpected time or at an unexpected frequency. For example, receiving a non-cell-defining synchronization signal and physical broadcast channel block (NCD-SSB) can cause intra- or inter-cell interference, synchronization loss, and radio link failure. Due to the periodic nature of NCD-SSBs after activation, these and potentially other issues can persist for reduced capability (RedCap) UEs and non-RedCap UEs. SUMMARY

[0007] Some aspects herein relate to an apparatus for wireless communication at a user equipment (UE). The UE can include at least one memory and at least one processor coupled with the at least one memory. The at least one processor can be operable to cause the UE to receive a first configuration for operating in a time division duplex (TDD) band having one or more downlink (DL) slots or DL symbols and one or more uplink (UL) slots or UL symbols. The at least one processor can be operable to cause the UE to receive a second configuration for receiving a non-cell-defining synchronization signal and physical broadcast channel block (NCD-SSB) and directional collision handling associated with the NCD-SSB.

[0008] Some aspects herein relate to an apparatus for wireless communication at a network node. The network node can include at least one memory and at least one processor coupled with the at least one memory. The at least one processor can be operable to cause the network node to transmit a first configuration for operating in a TDD band having one or more DL slots or DL symbols and one or more UL slots or UL symbols. The at least one processor can be operable to cause the network node to transmit a second configuration for directional collision handling for NCD-SSBs.

[0009] Some aspects described herein relate to a method of wireless communication performed at a UE. The method can include receiving a first configuration for operating in a TDD band having one or more DL slots or DL symbols and one or more UL slots or UL symbols. The method can include receiving a second configuration for receiving an NCD-SSB and directional collision handling associated with the NCD-SSB.

[0010] Some aspects herein relate to a method of wireless communication performed at a network node. The method can include transmitting a first configuration for operating in a TDD band having one or more DL slots or DL symbols and one or more UL slots or UL symbols. The method can include transmitting a second configuration for directional collision handling for NCD-SSBs.

[0025] Various aspects of the disclosure are described more fully below with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific 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 the disclosure to those skilled in the art. One skilled in the art can appreciate from the disclosure given herein that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus can be implemented or a method can be practiced using any amount of the aspects described herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. Any aspect of the disclosure disclosed herein can be embodied by one or more elements of a claim.

[0026] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as “elements”). These elements can be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0027] Certain network components transmit synchronization signals and physical broadcast channel (PBCH) blocks (SSBs) that help facilitate initial access and synchronization procedures of user equipment (UEs). An SSB is generally composed of two components: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The SSB provides time-domain synchronization, frequency-domain synchronization, cell search and identification, system information acquisition, and network access.

[0028] One type of SSB is referred to as a cell-defining SSB (CD-SSB). A CD-SSB includes a PSS, a SSS, and cell identification information, which can include a cell identifier, frame timing, and system information. The cell identification information helps a UE distinguish between different cells in a network and establish a connection with the appropriate cell. When a SSB is not associated with remaining minimum system information (RMSI) (e.g., system information block (SIB) 1 (SIB1)), the SSB is referred to as a non-cell-defining SSB (NCD-SSB), which can be used for performing radio link monitoring (RLM), bidirectional forwarding detection (BFD), and radio resource management (RRM) measurements within an active downlink (DL) BWP and for measurements for resource allocation (RA) resource selection when the active BWP does not contain a CD-SSB. A UE can be configured with multiple SSBs, provided that at most one SSB (e.g., a CD-SSB or a NCD-SSB) is configured per BWP. A NCD-SSB includes a PSS and a SSS, but omits cell identification information. A NCD-SSB can help enable redundancy, improve signal coverage, or assist with network load balancing.

[0029] At a UE, CD-SSBs and NCD-SSBs can “collide” when, for example, a NCD-SSB is transmitted on the same resources. Even if an offset is imposed on NCD-SSB transmissions, the offset can result in a NCD-SSB being transmitted on uplink (UL) resources. Without proper configuration, a UE can not be equipped to handle a NCD-SSB on UL resources. Since NCD-SSB configuration is specific to a BWP, it is likely that at least a portion of NCD-SSBs will be transmitted on UL resources frequently enough to cause problems such as intra-cell interference, inter-cell interference, loss of synchronization, and / or radio link failure, among others. Moreover, due to the periodic nature of NCD-SSB transmissions, problems resulting from collisions can persist at the UE. Additionally, the broadcast of NCD-SSBs can be based on the same transmission parameters as CD-SSBs, such as power boosting parameters, beam sweeping parameters, and the like, which can cause further collisions and, thus, interference between NCD-SSBs and CD-SSBs from the perspective of a UE.

[0030] Various aspects generally relate to reducing interference for NCD-SSB communications in a UE. Some aspects more specifically relate to configuring a UE to mitigate interference caused by a collision between an NCD-SSB and a CD-SSB. Some aspects more specifically relate to configuring a UE to mitigate interference and / or other issues that can occur when receiving at least a portion of an NCD-SSB during one or more DL slots or symbols and one or more UL slots or symbols. In some aspects, the configuration can define parameters for NCD-SSB reception, such as a time offset between the NCD-SSB and a reference CD-SSB, a periodicity of the NCD-SSB after activation, or a priority indication for NCD-SSB reception. In some aspects, the configuration can define rules for collision handling associated with the NCD-SSB, such as a verification of the presence of the NCD-SSB and a verification of UL resources in the presence of the NCD-SSB.

[0031] 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, the described techniques can be used to mitigate interference caused by receiving at least a portion of an NCD-SSB during one or more DL slots or symbols and one or more UL slots or symbols. For example, by configuring a UE to receive an NCD-SSB and directional collision handling associated with the NCD-SSB, some aspects reduce the likelihood of issues such as intra-cell or inter-cell interference, loss of synchronization between a UE and a network node, and radio link failure. Moreover, in some aspects, by configuring a UE to receive an NCD-SSB and directional collision handling associated with the NCD-SSB, persistent issues caused by the periodic nature of the NCD-SSB can be avoided or mitigated. For example, a UE can be configured to expect the NCD-SSB at least partially on UL resources. As another example, the time offset and / or periodicity of the NCD-SSB can be configured in a manner that prevents the NCD-SSB from being transmitted during UL resources, which can mitigate intra-cell interference, inter-cell interference, loss of synchronization, and radio link failure caused by the collision. Moreover, a UE can be configured with rules that the UE can apply to verify the NCD-SSB in UL, DL, or flexible slots or symbols, thereby reducing collisions between the NCD-SSB and a CD-SSB and mitigating potential interference that can result from such collisions.

[0032] Figure 1is a diagram illustrating examples of wireless networks. The wireless network 100 can be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or can include elements of a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, among others. The wireless network 100 can include one or more network nodes 110 (shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d), one UE 120, or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), or other network entities. The network node 110 is an entity that communicates with the UE 120. As illustrated, the network node 110 can include one or more network nodes. For example, the 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 RAN node (e.g., within a single device or unit). As another example, the network node 110 can be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed across 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).

[0033] In some examples, the network node 110 is or includes a network node (such as a RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a front-haul link or a mid-haul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a mid-haul link or with a core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a disaggregated network node 110) can include multiple network nodes, such as one or more RUs, one or more CUs, or one or more DUs. The network node 110 can include, for example, a NR network node, an LTE network node, a NodeB, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point or transmission reception point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, network equipment, and / or a RAN node. In some examples, the network nodes 110 can interconnect with one another or to one or more other network nodes 110 in the wireless network 100 using any suitable transport network, by various types of front-haul interfaces, mid-haul interfaces, or backhaul interfaces, such as direct physical connections, an air interface, or virtual networks.

[0034] Each network node 110 can provide communication coverage for a particular geographic area. In Third Generation Partnership Project (3GPP) the term "cell" can refer to a coverage area of a network node 110 or a subsystem of a network node 110 serving the coverage area, depending on the context in which the term is used.

[0035] The network nodes 110 can be macro cells, pico cells, femto cells, or another type of cell providing communication coverage. A macro cell can cover a relatively large geographic area (e.g., having a radius of several kilometers) and can allow unrestricted access by UEs 120 with service subscriptions. A pico cell can cover a relatively small geographic area (e.g., a business district, a home, or a campus) and can allow unrestricted access by UEs 120 with service subscriptions. A femto cell can cover a relatively small geographic area (e.g., a residence) and can allow restricted access by UEs 120 associated with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell can be referred to as a macro network node. A network node 110 for a pico cell can be referred to as a pico network node. A network node 110 for a femto cell can be referred to as a femto network node or a home network node.

[0036] In some aspects, the term “base station” or “network node” can refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a “base station” or “network node” can refer to a CU, a DU, a RU, a near real-time (near-RT) RAN intelligent controller (RIC), and / or a non-RT RIC. In some aspects, the term “base station” or “network node” can refer to one device configured to perform one or more functions, such as those described herein in connection with a network node 110. In some aspects, the term “base station” or “network node” can refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which can be located in the same geographic location or different geographic locations) can be configured to perform at least a portion of a function, or to repeat at least a portion of the function, and the term “base station” or “network node” can refer to any one or more of these different devices. In some aspects, the term “base station” or “network node” can 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” can refer to one of a base station function as opposed to another base station function. In this way, a single device can comprise more than one base station.

[0037] A network controller 130 can couple to a set of network nodes 110 and can provide coordination and control for the network nodes 110. The network controller 130 can communicate with the network nodes 110 via a backhaul communication link. The network nodes 110 can also communicate with one another directly, via wireless backhaul communication links or via wired backhaul communication links. In some aspects, the network controller 130 can be a CU or a core network device, or the network controller 130 can include a CU or a core network device.

[0038] Wireless network 100 can include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a network node 110 or a UE 120) and send a transmission of the data to a downstream station (e.g., a UE 120 or a network node 110). A relay station can be a UE 120 that can relay transmissions for other UEs 120. In Figure 1 In the example shown in FIG. 1, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d in order to facilitate communication between network node 110a and UE 120d. A network node 110 that relays

[0039] The UEs 120 can be dispersed throughout the wireless network 100, and each UE 120 can be stationary or mobile. A UE 120 can include, for example, an access terminal, a terminal, a mobile station or a subscriber unit. A UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a game device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart eyewear (e.g., augmented reality (AR), virtual reality (VR), mixed reality or extended reality (XR) head-mounted displays), a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, or any other suitable device that is configured to communicate via a wireless medium. Some UEs 120 (e.g., UEs 120a and 120e) can communicate directly with each other using one or more sidelink channels (e.g., without using a network node as an intermediary to communicate with each other).

[0040] Some UEs 120 can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC or eMTC UEs can include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags, that can communicate with a network node, another device (e.g., remote device), or some other entity. A

[0041] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using a network node 110 as an intermediary to communicate with one another). For example, UEs 120 can communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (which can include a vehicle-to-vehicle (V2V) protocol, where vehicles communicate directly with one another using, e.g., a PC5 interface, a vehicle-to-infrastructure (V2I) protocol, where a vehicle communicates with a roadside unit (RSU) or other infrastructure, or a vehicle-to-pedestrian (V2P) protocol, where a vehicle communicates with a pedestrian carrying, for example, a mobile device capable of D2D communications), or a mesh network. In such examples, a UE 120 can perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by the network node 110. In other examples, two or more UEs 120 can communicate using a vehicle-to-network-to-vehicle (V2N2V) protocol, for example, by communicating over a Uu interface using LTE and / or NR uplink and downlink.

[0042] In some aspects, UE 120 can include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 can receive a first configuration for operating in a TDD frequency band having one or more DL slots or DL symbols and one or more UL slots or UL symbols; and receive a second configuration for receiving a NCD-SSB and directional collision handling associated with the NCD-SSB. Additionally, or alternatively, the communication manager 140 can perform one or more other operations described herein.

[0043] In some aspects, the network node 110 can include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 can transmit a first configuration for operating in a TDD frequency band having one or more DL slots or DL symbols and one or more UL slots or UL symbols; and transmit a second configuration for receiving a NCD-SSB and directional collision handling associated with the NCD-SSB. Additionally, or alternatively, the communication manager 150 can perform one or more other operations described herein.

[0044] Figure 2 is a diagram illustrating an example network node in communication with a UE in a wireless network. The network node can correspond to Figure 1 the network node 110 of FIG. 1. Similarly, the UE can correspond to Figure 1 the UE 120 of FIG. 1. The network node 110 can be equipped with a set of antennas 234a through 234t, such as T antennas (T > 1). The UE 120 can be equipped with a set of antennas 252a through 252r, such as R antennas (R > 1). Figure 2 The network node 110 depicted in FIG. 2 includes one or more radio frequency components, such as antennas 234 and modem 232. In some examples, the network node 110 can include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 can not include radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0045] At the network node 110, a transmit processor 220 can receive data, intended for the UE 120 (or a set of UEs 120), from a data source 212. The transmit processor 220 can select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 can process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS(s) selected for the UE 120 and can provide data symbols for the UE 120. The transmit processor 220 can process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 can generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a PSS or an SSS). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, or the reference symbols, if 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 through 232t. Each output symbol stream can be provided to a modulator component (shown as MOD) of the modems 232 using a respective modulator component. Each modem 232 can process a respective output symbol stream (e.g., for OFDM) using a respective modulator component to obtain an output sample stream. Each modem 232 can further process (e.g., convert to analog, amplify, filter, or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 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 through 234t.

[0046] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) can receive the downlink signals from network node 110 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 through 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 can use a respective demodulator component to condition (e.g., filter, amplify, downconvert, or digitize) a received signal to obtain input samples. Each modem 254 can use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain received symbols from modems 254, can perform MIMO detection on the received symbols if applicable, and can provide detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, can provide decoded data for the UE 120 to a data sink 260, and can provide decoded control information and system information to a controller / processor 280. The term “controller / processor” can refer to one or more controllers and / or one or more processors. The channel processor can determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, or a CQI parameter, among other examples. In some examples, one or more components of the UE 120 can be included in a housing 284.

[0047] Network controller 130 can include communication unit 294, controller / processor 290, and memory 292. Network controller 130 can include, for example, one or more devices in a core network. Network controller 130 can communicate with network node 110 via communication unit 294.

[0048] One or more antennas (e.g., antennas 234a through 234t or antennas 252a through 252r) can include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, or antenna array can include one or more antenna elements (within a single housing or multiple housings), a set of co-planar antenna elements, a set of non-co-planar antenna elements, or one or more antenna elements coupled to one or more transmit or receive components (such as one or more components of a transceiver 230 or a modem 254) within a housing. Figure 2 One or more components of a transceiver 230 or a modem 254 can be included within a single housing or multiple housings.

[0049] On the uplink, at UE 120, a transmit processor 264 can receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, or CQI) from controller / processor 280. Transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from transmit processor 264 can be precoded by a TX MIMO processor 266 if applicable, further processed by modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, modems 254 of UE 120 can include modulators and demodulators. In some examples, UE 120 includes a transceiver. The transceiver can include any combination of antenna(s) 252, modems 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform any of the methods described herein.

[0050] At network node 110, the uplink signals from UE 120 or other UEs can be received by antennas 234, processed by modems 232 (e.g., demodulator components of modems 232, shown as DEMOD), detected by MIMO detector 236 if applicable, and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 can include communication unit 244 and can communicate with network controller 130 via communication unit 244. Network node 110 can include scheduler 246 to schedule one or more UEs 120 for downlink or uplink communications. In some examples, modems 232 of network node 110 can include modulators and demodulators. In some examples, network node 110 includes a transceiver. The transceiver can include any combination of antenna(s) 234, modems 232, MIMO detector 236, receive processor 238, transmit processor 220, or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform any of the methods described herein.

[0051] Controller / processor 240 of network node 110, controller / processor 280 of UE 120, or Figure 2Any other component in the system may perform one or more techniques associated with receiving an NCD-SSB and the directed conflict handling associated with that NCD-SSB, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, or... Figure 2 Any other component that can execute or direct, for example Figure 8 The process 800 Figure 9 The operation of process 900 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 or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code or program code) for wireless communication. For example, one or more instructions may cause the one or more processors of network node 110 or UE 120, UE 120, or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 or UE 120 (e.g., directly, or after compilation, transformation, or interpretation). Figure 8 The process 800 Figure 9 The operation of process 900 or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions, or interpret instructions, etc.

[0052] In some aspects, UE 120 includes components for receiving a first configuration for operating in a TDD band having one or more DL time slots or DL ​​symbols and one or more UL time slots or UL symbols; and components for receiving a second configuration for receiving an NCD-SSB and directional collision handling associated with the NCD-SSB. Components enabling UE 120 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.

[0053] In some aspects, network node 110 includes components for transmitting a first configuration for operation in a TDD band having one or more DL time slots or DL ​​symbols and one or more UL time slots or UL symbols; and components for transmitting a second configuration for receiving an NCD-SSB and directional collision handling associated with the NCD-SSB. Components enabling network node 110 to perform the operations described herein may include, for example, one or more of the following: communication manager 150, antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, TX MIMO processor 230, controller / processor 240, or memory 242.

[0054] Figure 3 This is a diagram illustrating example timelines 300 for CD-SSB 305a-305d (collectively referred to as 305) and NCD-SSB 310a-310b (collectively referred to as 310) in Time Division Duplex (TDD) band 315. Figure 3 As shown, TDD band 315 may include DL time slots or symbols (shown as D), flexible time slots or symbols (shown as F), and UL time slots or symbols (shown as U). UE 120 may receive a first configuration for operating in TDD band 315. Example timeline 300 also illustrates CD-SSB 305 and NCD-SSB 310. CD-SSB 305 may include PSS, SSS, and cell identification information. NCD-SSB 310 may include PSS and SSS, while some information about a particular network node 110 is omitted. In some aspects, UE 120 may receive a second configuration for receiving NCD-SSB 310 and directional conflict handling associated with NCD-SSB 310. With the second configuration, UE 120 may mitigate interference that would be caused by receiving some or a portion of NCD-SSB 310, for example, during DL time slots or symbols and UL time slots or symbols.

[0055] CD-SSB 305 may be transmitted by network node 110 on DL resources according to a first periodicity 320. NCD-SSB 310 may be transmitted by the same or different network node 110 according to a second periodicity 325. The second periodicity 325 may be a function of the first periodicity. For example, in some aspects, the second periodicity 325 is a multiple of the first periodicity (e.g., the first periodicity multiplied by an integer k, where k is greater than or equal to zero). In the case where the second periodicity 325 is a function of the first periodicity, particularly when k is zero or a positive integer, UE 120 will not receive NCD-SSB 310 during UL slots or symbols, thereby reducing interference and other problems.

[0056] In some respects, NCD-SSB 310 can withstand a time offset of 330. The time offset can shift the first NCD-SSB in NCD-SSB 310a relative to the reference CD-SSB 305a. NCD-SSB 310a and the reference CD-SSB 305a can be transmitted on the same cell (by the same network node) and have the same quasi-co-location (QCL) relationship. For example... Figure 3 As shown, time offset 330 is equal to the first periodicity 320. In some respects, time offset 330 can be a function of the first periodicity 320. The first transmission of NCD-SSB 310a in the initial or dedicated DLBWP can occur after time offset 330.

[0057] In some aspects, the second configuration defines a time window 335 for configuring or activating NCD-SSB 310a. In some aspects, NCD-SSB 310a may be activated by Radio Resource Control (RRC) signaling, Media Access Control (MAC) Control Element (MAC-CE) signaling, Downlink Control Information (DCI) signaling, and / or combinations thereof, etc. Therefore, through the second configuration, UE 120 can be configured to anticipate NCD-SSB 310a occurring after time window 335. In some aspects, the second configuration may define an application delay 340 that indicates a time period after time window 335 during which UE 120 can anticipate a first opportunity for NCD-SSB 310a.

[0058] As shown in example timeline 300, UE 120 operating on TDD band 315 receives an indication of the presence of NCD-SSB 310 in the active DL BWP, and UE 120 can expect that the symbol of NCD-SSB 310 will not be configured as a UL symbol by cell-specific TDD-UL-DL-Pattern, UE-specific TDD-UL-DL-Pattern, DCI (scheduling DCI or slot format indicator (SFI)), or MAC-CE (e.g., random access response (RAR)). In some aspects, the active DL BWP can be the initial DL BWP of the UE after releasing the RRC connection, or a dedicated RRC within a dedicated DL BWP of a UE with an RRC connection. For example, NCD-SSB 310 in the initial DL BWP can be configured by the last serving cell in the RRC Release message.

[0059] In some respects, conflicts between NCD-SSB 310 and UL slots or symbols on DL slots or symbols can be avoided by restricting the configuration of the candidate time offset of NCD-SSB 310. For example, as described above, the candidate time offset between NCD-SSB 310 and CD-SSB 305 transmitted by the same cell (e.g., network node 110) can be configured to be a periodic multiple of CD-SSB 305, where k is a zero or a positive integer.

[0060] In some aspects, the time window 335 for NCD-SSB configuration and / or activation, the application delay 340 for NCD-SSB configuration and / or activation, or the reference CD-SSB 305a associated with the time offset configuration for NCD-SSB 310 may be additionally provided to the UE 120 by the network node 110. In some aspects, the application delay 340 for NCD-SSB configuration and / or activation may depend on the frequency range, the reference parameter set of the active DL BWP, the BWP handover delay, or the capabilities of the UE 120.

[0061] Figure 4 Example 400 is associated with UL resource verification for avoiding or mitigating conflicts related to NCD-SSB. Example 400 includes communication between a UE (such as UE 120) and a network node (such as network node 110).

[0062] As shown by reference numeral 405 in the attached figure, the network node can send and the UE can receive CD-SSB communications, system information and / or combinations thereof, etc.

[0063] As shown by reference numeral 410 in the attached figure, a network node can send and the UE can receive UL and / or DL ​​resource configuration and / or activation in the UE's active DL BWP.

[0064] As shown by reference numeral 415 in the attached figure, the network node can send and the UE can receive scheduling information for UL transmission in the active UL BWP for the UE.

[0065] As shown by reference numeral 420 in the attached figure, the UE can verify UL resources. In some respects, the UE can verify UL resources independently of the NCD-SSB. For example, before the UE makes a transmission on the active UL BWP, the UE can verify the UL resources configured / indicated by the network node on that active UL BWP. UL resource configuration / indication can be carried by system information, RRC signaling, MAC-CE, DCI and / or combinations thereof, etc. When the SSB is used for UL resource verification, the UE can consider the CD-SSB regardless of whether the NCD-SSB is configured / activated in the active DL BWP.

[0066] In some respects, if a UE operating on a TDD band (such as a RedCap or non-RedCap UE) receives an indication of the presence of an NCD-SSB in an active DLBWP, and the UE is configured with a set of valid UL resources that do not overlap with the CD-SSB, then the UE can expect that the NCD-SSB does not exist on that set of valid UL resources and before the first symbol / slot of that set of valid UL resources. 间隙On the symbols (discussed in more detail below). In some respects, for RedCap UEs in TDD, the network (such as Radio Network 100) can ensure that the time-domain location of the NCD-SSB is a subset of the time-domain location of the CD-SSB. The CD-SSB and NCD-SSB can be transmitted by the serving cell, and the CD-SSB can be transmitted via the active DL BWP containing the NCD-SSB. This set of valid UL resources can be associated with the transmission timing / opportunity for UL channels (e.g., Physical Random Access Channel (PRACH), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS)), and this transmission timing / opportunity can span one or more time slots or sub-time slots (e.g., the duration of a sub-time slot can be a portion of a time slot (e.g., Type B PUSCH mapping)). This set of valid UL resources can be configured by system information or RRC signaling, which can be indicated to the UE via system information, RRC signaling, MAC-CE signaling, or DCI signaling.

[0067] This set of valid UL resources can be configured to be at least N after the last CD-SSB block sent by the serving cell. 间隙 It begins at the symbol. N 间隙The value can be configured by the network node and can depend on the frequency range, duplex mode (TDD, Subband Full-Duplex (SBFD), High-Definition Frequency Division Duplex (HD-FDD)), the reference parameter set of the active DL BWP and / or UL BWP, and / or the type, format, or waveform of the UL channel associated with that set of valid UL resources (e.g., PRACH, PUSCH, PUCCH, SRS). The active DL BWP can be the initial DL BWP of the UE after releasing an RRC connection, or a dedicated DL BWP for a UE with an RRC connection (e.g., operating in RRC connection mode). For example, for a UE without an RRC connection, the NCD-SSB can be configured by the last serving cell in the RRC release message. In some respects, for a RedCap UE that indicates the ability to use an SSB (e.g., an SS / PBCH block) provided by a NonCellDefiningSSB for PUSCH transmission in the RRC_INACTIVE state, if the UE is configured with a NonCellDefiningSSB in ncd-SSB-RedCapInitialBWP-SDT, then during PUSCH transmission in the RRC_INACTIVE state, the UE may use the SS / PBCH block provided by the NonCellDefiningSSB for purposes that the UE would otherwise use to obtain SIB1.

[0068] In some respects, the UE can receive indications of the presence and / or activation of the NCD-SSB via RRC signaling, MAC-CE signaling, or DCI signaling. In some respects, if the active DL BWP provided by BWP-DownlinkDedicated or the initial DL BWP provided during a PUSCH transmission procedure in RRC_INACTIVE (RRC inactive) state includes SS / PBCH blocks provided by a NonCellDefiningSSB, then these SS / PBCH blocks and the SS / PBCH blocks used by the UE to obtain SIB1 have the same QCL attributes if they have the same index.

[0069] Figure 5Example 500 is associated with UL resource verification based on one or more time slots. A first time slot ΔT1 may be defined between the last time slot or symbol of CD-SSB transmission 505 and a first time slot or symbol of a set of UL resources 510 for UE 120. A second time slot ΔT2 may be defined between the last time slot or symbol of NCD-SSB 515 and a first time slot or symbol of flexible (shown as F) or UL (shown as U) resource 520. In some aspects, if the active DLBWP of UE 120 includes NCD-SSB 515 but not CD-SSB transmission 505, then UE 120 may consider the first time slot ΔT1 instead of the second time slot ΔT2 to verify the UL resource. If the active DLBWP of UE 120 includes CD-SSB transmission 505, then UE 120 may consider the first time slot ΔT1 instead of the second time slot ΔT2 to verify the UL resource 520. If UE 120's active DL BWP does not include either NCD-SSB 515 or CD-SSB transmission 505, then UE 120 may consider the first timing gap ΔT1 instead of the second timing gap ΔT2 to verify UL resource 520. In some respects, if the first timing gap ΔT1 is greater than or equal to N... 间隙 If NCD-SSB 515 is configured and / or activated in the active DL BWP of UE 120, then UE 120 can expect the second timing gap ΔT2 to be no less than N. 间隙 .

[0070] Figure 6 Example 600 is associated with verifying the presence of NCD-SSB on DL and flexible time slots or symbols. Example 600 includes communication between a UE (such as UE 120) and a network node (such as network node 110).

[0071] As shown by reference numeral 605 in the attached figure, the network node can send and the UE can receive CD-SSB communications, system information and / or combinations thereof, etc.

[0072] As shown by reference numeral 610 in the attached figure, a network node can send and the UE can receive UL and / or DL ​​resource configuration and / or activation in the UE's active DL BWP.

[0073] As shown by reference numeral 615 in the attached figure, network nodes can transmit and UEs can receive network assistance information. Network assistance information may include SIBs, neighboring cell information, location assistance information, timing advance parameters, and / or other parameters or settings related to network performance (such as, for example, power control settings, transmission modes, or adaptive modulation and decoding schemes, etc.).

[0074] As shown by reference numeral 620 in the attached figure, the network node can send and the UE can receive configuration and / or scheduling information for UL transmission on flexible time slots or symbols.

[0075] As shown by reference numeral 625, the UE can verify the presence of the NCD-SSB on the DL and / or flexible time slots or symbols. In some aspects, the UE can verify the presence of the NCD-SSB when the time offset of the NCD-SSB is not a function (e.g., a multiple) of the periodicity of the CD-SSB, as described above. In some aspects, the UE can verify the presence of the NCD-SSB before performing a measurement of the NCD-SSB. The UE's verification of the NCD-SSB can be based on the TDD time slot format configuration, network auxiliary information (e.g., rules and / or priorities for the flexible symbol configuration of the NCD-SSB), and the timeline used to receive UL scheduling information.

[0076] In some aspects, if a UE operating on a TDD band receives an indication of the presence of an NCD-SSB in an active DL BWP and the time offset condition of the NCD-SSB is not met (e.g., the time offset of the NCD-SSB is not equal to k times the periodicity of the NCD-SSB), the UE can be configured to verify the presence of the NCD-SSB for a period of time prior to measuring the verified symbol of the NCD-SSB. In some aspects, the UE can anticipate that the symbol of the NCD-SSB is not present on a symbol configured as a UL symbol by a cell-specific TDD-UL-DL-Pattern (in system information) or a UE-specific TDD-UL-DL-Pattern (via RRC), and will not receive the NCD-SSB on the UL symbol configured by system information or RRC signaling. For example, a UL symbol in a TDD slot may be invalid for the reception and / or measurement of the NCD-SSB.

[0077] If a UE is configured by RRC to receive NCD-SSBs on a set of flexible symbols in a TDD time slot, the network node can provide additional information to help the UE verify NCD-SSB reception. For example, if the flexible symbols are configured by RRC or indicated by SFI, the network node can provide a priority flag to the UE in system information or RRC signaling, and this priority flag can indicate to the UE whether to receive NCD-SSBs on that set of flexible symbols. Within the same cell, the priority flag used for receiving NCD-SSBs on flexible symbols configured by RRC may differ from the priority flag used for receiving NCD-SSBs on flexible symbols indicated by SFI.

[0078] In some respects, if the DCI and / or MAC-CE instruct the UE to receive an NCD-SSB on a set of DL and flexible symbols in a TDD time slot, the network node may specify deterministic rules or provide gap thresholds to assist the UE in verification. For example, the UE may be configured by the network node to receive or skip an NCD-SSB on that set of flexible symbols. Alternatively, the UE may be configured to receive an NCD-SSB if the duration (e.g., a third timing gap ΔT3) between the last symbol of the DCI (e.g., the Physical Downlink Control Channel (PDCCH)) or MAC-CE (e.g., the Physical Downlink Shared Channel (PDSCH)) and the first symbol of the candidate NCD-SSB block is greater than or equal to the gap threshold. Otherwise, the UE may not receive an NCD-SSB.

[0079] Figure 7 Example 700 is associated with resource verification on a flexible time slot or symbol 705 based on a time gap. As indicated by reference numeral 710, a network node may send configuration and / or scheduling information for UL transmission on a flexible time slot or symbol 705. This configuration and / or scheduling information may be sent before the first flexible time slot or symbol 705. A third time gap ΔT3 may be defined between the last time slot or symbol of the configuration and / or scheduling information 710 and the first flexible time slot or symbol 705. If the third time gap ΔT3 is greater than a gap threshold, the UE may be configured to expect the presence of NCD-SSB 715 on the flexible time slot or symbol 705. In some aspects, such as Figure 7 As shown in Example 700, the candidate slot or symbol for NCD-SSB 715 may at least partially overlap with the flexible slot or symbol 705.

[0080] Figure 8 This is a flowchart of example process 800 performed at or by a UE that supports targeted conflict handling for NCD-SSB. Example process 800 is an example in which a UE (e.g., UE 120 or a device of the UE) performs operations associated with targeted conflict handling for NCD-SSB.

[0081] like Figure 8 As shown, in some aspects, process 800 may include receiving a first configuration (block 810) for operation in a TDD band having one or more DL time slots or DL ​​symbols and one or more UL time slots or UL symbols. For example, a UE (such as by using...) Figure 10 The communication manager 140 or receiving component 1002 depicted herein may receive a first configuration for operation in a TDD band having one or more DL time slots or DL ​​symbols and one or more UL time slots or UL symbols, as described above.

[0082] likeFigure 8 Further shown, in some aspects, process 800 may include receiving a second configuration (block 820) for receiving an NCD-SSB and directional conflict handling associated with that NCD-SSB. For example, a UE (such as by using...) Figure 10 The communication manager 140 or receiving component 1002 depicted may receive a second configuration for receiving NCD-SSB and directional conflict handling associated with the NCD-SSB, as described above.

[0083] like Figure 8 Further shown, in some aspects, process 800 may include mitigating interference caused by receiving at least a portion of the NCD-SSB during one or more DL time slots or symbols and one or more UL time slots or symbols (box 830). For example, the UE (such as by using...) Figure 10 The communication manager 140 or mitigation component 1008 depicted herein can mitigate interference caused by receiving at least a portion of the NCD-SSB during one or more DL time slots or symbols and one or more UL time slots or symbols, as described above.

[0084] Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below or in conjunction with one or more other processes described elsewhere in this document.

[0085] In the first additional aspect, the second configuration for receiving the NCD-SSB includes a timing offset between the NCD-SSB and a reference CD-SSB, the periodicity of the NCD-SSB, a frequency mapping for the NCD-SSB, a time window for configuring or activating signaling reception of the NCD-SSB, or an application delay for receiving the NCD-SSB after the time window.

[0092] In the eighth additional aspect, the indication of the presence or activation of the NCD-SSB is received, either alone or in combination with one or more of the first to seventh aspects, via RRC signaling, MAC-CE signaling, or DCI.

[0093] In the ninth additional aspect, either alone or in combination with one or more of the first to eighth aspects, process 800 includes receiving a network configuration for one of a time window, an application delay, or a reference CD-SSB associated with a time offset configuration, wherein the time window, the application delay, or the reference CD-SSB is associated with the presence or activation of the NCD-SSB.

[0094] In the tenth additional aspect, alone or in combination with one or more of the first to ninth aspects, the application delay is based at least in part on one or more of the frequency range, the reference parameter set of the active DL BWP, the BWP handover delay, or the UE capability.

[0095] In the eleventh additional aspect, either alone or in combination with one or more of the first to tenth aspects, process 800 includes: receiving a CD-SSB and SIB output by the serving cell; receiving UL resource configuration or UL activation or one or more of DL resource configuration or DL ​​activation in an active DL BWP; and receiving scheduling information for UL transmission in the active UL BWP, wherein the second configuration for directional conflict handling associated with the NCD-SSB includes a set of rules for verifying resources in the active UL BWP and for transmitting the UL reference signal or UL channel on the active UL BWP after verifying the UL resources allocated for the UL reference signal or UL channel.

[0096] In the twelfth additional aspect, alone or in combination with one or more of the first to eleventh aspects, the second configuration for directional conflict handling associated with the NCD-SSB includes a set of rules for providing a gap between a first symbol or time slot of a set of valid UL resources and the last symbol or time slot of the DL reference signal or DL ​​channel.

[0097] In the thirteenth additional aspect, alone or in combination with one or more of the first to twelfth aspects, process 800 includes: receiving the CD-SSB outside a first active DL bandwidth portion that includes the NCD-SSB, receiving the CD-SSB outside a second active DL BWP that does not include the NCD-SSB, or receiving the NCD-SSB in a third active DL BWP that includes the NCD-SSB.

[0098] In the fourteenth additional aspect, alone or in combination with one or more of the first to thirteenth aspects, the first configuration for operation in the TDD band includes a set of valid UL resources associated with a transmission timing or opportunity for a UL reference signal or UL channel, wherein the transmission timing or opportunity spans one or more time slots or sub-time slots.

[0099] In the fifteenth additional aspect, alone or in combination with one or more of the first to fourteenth aspects, the set of valid UL resources is configured by system information or radio resource control signaling.

[0101] In the seventeenth additional aspect, alone or in combination with one or more of the first to sixteenth aspects, the set of valid UL resources begins after the last CD-SSB block sent by the serving cell, and the number of symbols between the last CD-SSB block and the set of valid UL resources is greater than or equal to the size of the gap.

[0102] In the eighteenth additional aspect, alone or in combination with one or more of the first to seventeenth aspects, the size of the gap is based at least in part on one or more of the following: frequency range, duplex mode, reference parameter set of active DL or UL bandwidth portion, or type, format, or waveform of the UL channel associated with the set of valid UL resources.

[0103] In the nineteenth additional aspect, alone or in combination with one or more of the first to eighteenth aspects, the second configuration for directional conflict handling associated with the NCD-SSB includes a set of rules for applying a first timing offset or a second timing offset, wherein the first timing offset is the time between the last time slot or symbol of the CD-SSB received from the serving cell and the first time slot or symbol of a set of UL resources transmitted by the UE in the active UL BWP, and wherein the second timing offset is the time between the last time slot or symbol associated with the NCD-SSB received from the serving cell in the active DL BWP and the first symbol of a flexible time slot or a UL time slot transmitted by the UE in the active UL BWP.
