[0002] This application claims priority to U.S. patent application No. 17 / 807,561, filed on June 17, 2022, which is assigned to the assignee of the present application and is hereby expressly incorporated by reference in its entirety, as if fully set forth below and for all applicable purposes. Background Art Technical Field

[0003] Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for spectrum sharing between networks.

[0004] Related technologies

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts or other similar types of services. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available wireless communication system resources with those users.

[0006] Although wireless communication systems have made tremendous technical progress over the years, challenges still exist. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and wireless receivers. Therefore, there is a continuous desire to improve the technical performance of wireless communication systems, including, for example: improving the speed and data carrying capacity of communications, improving the efficiency of using shared communication media, reducing the power used by transmitters and receivers when performing communications, improving the reliability of wireless communications, avoiding redundant transmission and / or reception and related processing, improving the coverage area of ​​wireless communications, increasing the number and types of devices that can access wireless communication systems, increasing the ability of different types of devices to communicate with each other, increasing the number and types of wireless communication media available for use, etc. Therefore, there is a need to further improve wireless communication systems to overcome the above-mentioned technical challenges and other challenges. Summary of the invention

[0007] In some aspects, the terrestrial network and the non-terrestrial network (NTN) may be configured to operate in the same spectrum range, such as 6 GHz to 24 GHz (e.g., referred to as FR3). For example, the terrestrial network may be configured to communicate in FR3, and the NTN may operate in a frequency range including FR3 (e.g., 5 GHz to 100 GHz).

[0008] Thus, in some aspects, two networks in the same area (e.g., operated by different network operators) may share the same spectrum range (e.g., FR3). Thus, aspects of this document relate to complementary spectrum sharing between networks. Such complementary spectrum sharing allows devices in two networks to communicate in their respective networks without interfering with the other network. Thus, more networks may be operated in the same geographic area without the need to allocate different frequency bands for different networks.

[0009] One aspect provides a method for wireless communication by a first network entity of a first network of a first network operator. The method includes: receiving frequency allocation information indicating a first allocation pattern from a second network entity of a second network of a second network operator, the first allocation pattern identifying a corresponding frequency channel band of a frequency band spanning a plurality of frequency channel bands for each cell in at least one cell, wherein the first allocation pattern identifies a first frequency channel band in the plurality of frequency channel bands for a first cell in the at least one cell; and transmitting to at least a first user equipment (UE) an indication indicating that a second frequency channel band in the plurality of frequency channel bands different from the first frequency channel band is used for communication in the first cell.

[0010] Another aspect provides a method for wireless communication by a first network entity of a first network of a first network operator. The method includes: transmitting frequency allocation information indicating a first allocation pattern to a second network entity of a second network of a second network operator, the first allocation pattern identifying a corresponding frequency channel band of a frequency band spanning multiple frequency channel bands for each beam of at least one beam of the first network, wherein the first allocation pattern identifies a first frequency channel band of the multiple frequency channel bands for a first beam of the at least one beam; and transmitting an indication to at least a first UE indicating to use the first frequency channel band for communication in the first beam.

[0011] Other aspects provide: an apparatus operable to, configured to, or otherwise adapted to perform any one or more of the foregoing methods and / or those described elsewhere herein; a non-transitory computer-readable medium comprising instructions that, when executed by a processor of the apparatus, cause the apparatus to perform the foregoing methods and those described elsewhere herein; a computer program product embodied on a computer-readable storage medium comprising code for performing the foregoing methods and those described elsewhere herein; and / or an apparatus comprising components for performing the foregoing methods and those described elsewhere herein. By way of example, an apparatus may include a processing system, a device having a processing system, or a processing system cooperating through one or more networks.

[0026] Various aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for spectrum sharing between networks, such as between a non-terrestrial network (NTN) and a terrestrial network. Although certain aspects are described for spectrum sharing between an NTN and a terrestrial network, it should be noted that aspects of the present invention may be applicable to spectrum sharing between other types of networks, networks of the same type, networks operated by the same or different operators, and the like.

[0027] In a wireless communication system, different network operators may provide network coverage in the same geographic location. For example, a first network operator may operate a first network whose coverage at least partially overlaps with the coverage of a second network operated by a second network operator. In one example, the overlap of coverage operated by different network operators occurs between an NTN (e.g., a satellite-based network) and a terrestrial network.

[0028] In some aspects, the terrestrial network and the non-terrestrial network can be configured to operate in the same spectrum range, such as 6 GHz to 24 GHz (e.g., referred to as FR3). For example, the terrestrial network can be configured to communicate in FR3, and the NTN can operate in a frequency range including FR3 (e.g., 5 GHz to 100 GHz).

[0029] Thus, in some aspects, two networks in the same area (e.g., operated by different network operators) may share the same spectrum range (e.g., FR3). Thus, aspects of this document relate to complementary spectrum sharing between networks. Such complementary spectrum sharing allows devices in two networks to communicate in their respective networks without interfering with the other network. Thus, more networks may be operated in the same geographic area without the need to allocate different frequency bands for different networks.

[0030] In complementary spectrum sharing, different portions of a spectrum range (e.g., including a continuous frequency range) may be allocated to different networks in the same geographic area (e.g., a cell). For example, the spectrum range may be divided into multiple frequency bands (e.g., an FR3 band may have a 200 MHz bandwidth). Each frequency band may be a continuous subset of the frequencies of the spectrum. Different networks may share a frequency band, such as by further dividing the frequency band into multiple frequency channel bands (FCBs). In some aspects, each FCB is a continuous subset of the frequencies of the frequency band. Thus, different FCBs may be allocated to different networks in the same geographic area to allow spectrum sharing.

[0031] Certain aspects of the present invention provide techniques for a first network to communicate to a second network information indicating what FCB the first network uses to communicate in each of a plurality of geographic regions (e.g., cells). Thus, the second network can avoid using the same FCB as the first network in the same geographic region to avoid interference between the first network and the second network. In certain aspects, a first network entity (e.g., a base station (BS), a central network entity, etc.) of the first network communicates the information to a second network entity of the second network, such as directly or indirectly (e.g., via a database, such as a third-party database). The communication between the first network entity and the second network entity can be wired and / or wireless.

[0032] In some aspects, the NTN entity of the NTN communicates information indicating its FCB allocation to the ground network (TN) entity of the ground network. When communicating on the downlink, such as communicating with a user equipment (UE), the base station (BS) of the NTN (referred to as the NTNBS) may send a signal as a plurality of beams, wherein each beam covers a given geographical area. In addition, when communicating on the downlink, the BS of the ground network (referred to as the TNBS) may send a signal in a geographical area referred to as a cell. In some aspects, each beam of the NTNBS is associated with a corresponding FCB for sending a signal using the beam. Therefore, in some aspects, the NTN entity communicates information indicating the FCB allocation of each beam of the NTNBS to the TN entity. The information may further indicate the geographical location covered by each beam. The TN entity may then determine which cells (e.g., associated with one or more TNBS) overlap with which beams. In the case where one or more beams overlap with a cell, the TN entity may allocate to the TNBS of the cell an FCB different from one or more FCBs used by the NTNBS in the one or more beams. Therefore, the TNBS of the TN and the NTNBS of the NTN will not use the same FCB in the same geographical location, thereby avoiding interference.

[0033] Introduction to wireless communication networks

[0034] The techniques and methods described herein can be used in various wireless communication networks. Although various aspects may be described herein using terms commonly associated with 3G, 4G and / or 5G wireless technologies, various aspects of the present disclosure may also be applicable to other communication systems and standards not explicitly mentioned herein.

[0035] Figure 1 An example of a wireless communication network 100 is depicted in which various aspects described herein may be implemented.

[0036] In general, the wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). A network entity is typically a communication device and / or a communication function performed by a communication device (e.g., user equipment (UE), base station (BS), component of a BS, server, etc.). For example, various functions of a network and various devices associated with and interacting with the network may be considered network entities. In addition, the wireless communication network 100 includes ground aspects, such as ground-based network entities (e.g., BS 102), and non-ground aspects, such as satellites 140 and aircraft 145, which may include airborne network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., ground BSs) and user equipment.

[0037] In the depicted example, the wireless communication network 100 includes a BS 102, a UE 104, and one or more core networks (such as an evolved packet core (EPC) 160 and a 5G core (5GC) network 190) that interoperate to provide communication services over various communication links (including wired and wireless links).

[0038] Figure 1 Various example UEs 104 are depicted, which may more generally include: a cellular phone, a smart phone, a Session Initiation Protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player, a camera, a game console, a tablet computer, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, an Internet of Things (IoT) device, an Always-On (AON) device, an edge processing device, or other similar devices. UE 104 may also be more generally referred to as a mobile device, a wireless device, a wireless communication device, a station, a mobile station, a subscriber station, a mobile subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, and others.

[0039] BS 102 wirelessly communicates with (e.g., transmits signals to or receives signals from) UE 104 via communication link 120. Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also referred to as a reverse link) transmissions from UE 104 to BS 102 and / or downlink (DL) (also referred to as a forward link) transmissions from BS 102 to UE 104. In various aspects, communication link 120 may employ multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity.

[0040] BS 102 may generally include: Node B, enhanced Node B (eNB), next generation enhanced Node B (ng-eNB), next generation Node B (gNB or gNodeB), access point, base transceiver station, radio base station, radio transceiver, transceiver function, transmission and reception point, and / or other. Each of BS 102 may provide communication coverage for a corresponding geographic coverage area 110, which may sometimes be referred to as a cell, and may overlap in some cases (e.g., small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, a BS may provide communication coverage for a macro cell (covering a relatively large geographic area), a pico cell (covering a relatively small geographic area, such as a stadium), a femto cell (relatively small geographic area (e.g., a home)), and / or other types of cells.

[0041] Although BS102 is depicted as a single communication device in various aspects, BS102 can be implemented in various configurations. For example, one or more components of the base station may be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, to name a few examples. In another example, various aspects of the base station may be virtualized. More generally, a base station (e.g., BS102) may include components located at a single physical location or components located at various physical locations. In an example in which the base station includes components located at various physical locations, the various components may each perform a function so that the various components together implement functionality similar to that of a base station located at a single physical location. In some aspects, a base station including components located at various physical locations may be referred to as a decomposed radio access network architecture (such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture). Figure 2 An example decomposed base station architecture is depicted and described.

[0042] Different BSs 102 within the wireless communication network 100 may also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 via a first backhaul link 132 (e.g., an S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) may interface with the 5GC 190 via a second backhaul link 184. The BSs 102 may communicate with each other directly or indirectly (e.g., via the EPC 160 or the 5GC 190) over a third backhaul link 134 (e.g., an X2 interface), which may be wired or wireless.

[0043] The wireless communication network 100 may subdivide the electromagnetic spectrum into various categories, frequency bands, channels, or other characteristics. In some aspects, the subdivision is provided based on wavelength and frequency, where frequency may also be referred to as a carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410 MHz-7125 MHz, which is often (interchangeably) referred to as "below 6 GHz". Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250 MHz-52,600 MHz, which is sometimes (interchangeably) referred to as "millimeter wave" ("mmW" or "mmWave"). A base station (e.g., a mmWave base station such as BS180) configured to communicate using mmWave / near mmWave radio bands may utilize beamforming (e.g., 182) with a UE (e.g., 104) to improve path loss and range.

[0044] The communication link 120 between the BS 102 and, for example, the UE 104 may be through one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, and / or other MHz) and may be aggregated in various aspects. The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL).

[0045] Communications using higher frequency bands may have higher path loss and shorter range than communications at lower frequencies. Therefore, some base stations (e.g. Figure 1 180) can utilize beamforming 182 with UE 104 to improve path loss and range. For example, BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels and / or antenna arrays, to facilitate beamforming. In some cases, BS 180 may send beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamformed signals from BS 180 in one or more receive directions 182". UE 104 may also send beamformed signals to BS 180 in one or more transmit directions 182". BS 180 may also receive beamformed signals from UE 104 in one or more receive directions 182'. BS 180 and UE 104 may then perform beam training to determine the best receive direction and transmit direction for each of BS 180 and UE 104. It is worth noting that the transmit direction and receive direction of BS 180 may be the same or different. Similarly, the transmit direction and receive direction of UE 104 may be the same or different.

[0046] Wireless communication network 100 also includes Wi-Fi AP 150 that communicates with Wi-Fi stations (STAs) 152 via communication links 154 in, for example, the 2.4 GHz and / or 5 GHz unlicensed spectrum.

[0047] Certain UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and / or a physical sidelink feedback channel (PSFCH).

[0048] The EPC 160 may include various functional components, including: a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and / or a packet data network (PDN) gateway 172, such as in the depicted example. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, the MME 162 provides bearer and connection management.

[0049] Generally speaking, user Internet Protocol (IP) packets are delivered through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation and other functions. The PDN Gateway 172 and the BM-SC 170 are connected to the IP Services 176, which may include, for example, the Internet, an Intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) streaming media service, and / or other IP services.

[0050] The BM-SC 170 may provide functionality for MBMS user service configuration and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS delivery, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and / or may be used to schedule MBMS delivery. The MBMS Gateway 168 may be used to distribute MBMS services to BSs 102 belonging to a multicast broadcast single frequency network (MBSFN) area broadcasting a specific service, and / or may be responsible for session management (start / stop) and for collecting eMBMS related charging information.

[0051] 5GC 190 may include various functional components, including: access and mobility management function (AMF) 192, other AMFs 193, session management function (SMF) 194, and user plane function (UPF) 195. AMF 192 may communicate with unified data management (UDM) 196.

[0052] AMF 192 is a control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides, for example, Quality of Service (QoS) flow and session management.

[0053] Internet Protocol (IP) packets are delivered through UPF 195, which is connected to IP Services 197 and provides IP address allocation for UEs and other functions for 5GC 190. IP Services 197 may include, for example, the Internet, Intranet, IMS, PS streaming services, and / or other IP services.

[0054] In various aspects, a network entity or network node may be implemented as a converged base station, a decomposed base station, a component of a base station, an integrated access and backhaul (IAB) node, a relay node, a sidelink node, to name a few examples.

[0055] Figure 2 An example disaggregated base station 200 architecture is depicted. The disaggregated base station 200 architecture may include one or more central units (CUs) 210 that may communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more disaggregated base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a service management and orchestration (SMO) framework 205, or both. The CU 210 may communicate with one or more distributed units (DUs) 230 via respective midhaul links, such as an F1 interface. The DU 230 may communicate with one or more radio units (RUs) 240 via respective fronthaul links. The RU 240 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 240.

[0056] Each of the units (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO framework 205) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of the unit may be configured to communicate with one or more of the other units via a transmission medium. For example, the units may include a wired interface configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally or alternatively, the unit may include a wireless interface that may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver) configured to receive signals on a wireless transmission medium or send signals to one or more of the other units, or both.

[0057] In some aspects, CU 210 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by CU 210. CU210 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP)), control plane functionality (e.g., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 210 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 210 may be implemented to communicate with DU 230 for network control and signaling.

[0058] DU 230 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 240. In some aspects, DU 230 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to a functional split such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0059] The lower layer functionality may be implemented by one or more RUs 240. In some deployments, a RU 240 controlled by a DU 230 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable the implementation of the DU 230 and the CU 210 in a cloud-based RAN architecture (such as a vRAN architecture).

[0060] The SMO framework 205 may be configured to support RAN deployment and configuration of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some specific implementations, the SMO framework 205 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 211) via the O1 interface. Additionally, in some specific implementations, the SMO framework 205 may communicate directly with one or more RUs 240 via the O1 interface. The SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of the SMO framework 205 .

[0061] The non-RT RIC 215 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 225. The non-RT RIC 215 may be coupled to or in communication with the near-RT RIC 225 (such as via an A1 interface). The near-RT RIC 225 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 210, one or more DUs 230, or both, and the O-eNB with the near-RT RIC 225.

[0062] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 225 and may be received from a non-network data source or from a network function at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to adjust RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 205 (such as via reconfiguration of O1) or via creation of RAN management policies (such as A1 policies).

[0063] Figure 3 Aspects of an example BS 102 and UE 104 are depicted.

[0064] In general, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a-334t (collectively 334), transceivers 332a-332t (collectively 332) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., data source 312) and wireless reception of data (e.g., data sink 339). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement various functions described herein related to wireless communication.

[0065] In general, the UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-352r (collectively 352), transceivers 354a-354r (collectively 354) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., retrieved from a data source 362) and wireless reception of data (e.g., provided to a data sink 360). The UE 104 includes a controller / processor 380 that can be configured to implement various functions described herein related to wireless communications.

[0066] Regarding example downlink transmissions, BS 102 includes a transmit processor 320 that can receive data from a data source 312 and control information from a controller / processor 340. The control information can be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical HARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), and / or others. In some examples, the data can be for a physical downlink shared channel (PDSCH).

[0067] The transmit processor 320 may process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmit processor 320 may also generate reference symbols (such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS)).

[0068] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols, where applicable, and may provide an output symbol stream to a modulator (MOD) in a transceiver 332a-332t. Each modulator in the transceiver 332a-332t may process a corresponding output symbol stream to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators in the transceivers 332a-332t may be transmitted via antennas 334a-334t, respectively.

[0069] To receive downlink transmissions, UE 104 includes antennas 352a-352r that can receive downlink signals from BS 102 and can provide received signals to demodulators (DEMODs) in transceivers 354a-354r, respectively. Each demodulator in transceivers 354a-354r can condition (e.g., filter, amplify, downconvert, and digitize) a corresponding received signal to obtain input samples. Each demodulator can further process the input samples to obtain received symbols.

[0070] A MIMO detector 356 may obtain received symbols from all demodulators in transceivers 354a-354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 104 to a data sink 360, and provide decoded control information to a controller / processor 380.

[0071] With respect to example uplink transmissions, the UE 104 also includes a transmit processor 364 that may receive and process data from a data source 362 (e.g., for a PUSCH) and control information from a controller / processor 380 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 364 may also generate reference symbols for reference signals (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 364 may be pre-decoded by a TX MIMO processor 366, if applicable, further processed by a modulator in the transceivers 354a-354r (e.g., for SC-FDM), and transmitted to the BS 102.

[0072] At BS 102, uplink signals from UE 104 may be received by antennas 334 a-334 t, processed by demodulators in transceivers 332 a-332 t, detected by MIMO detector 336 if applicable, and further processed by receive processor 338 to obtain decoded data and control information transmitted by UE 104. Receive processor 338 may provide decoded data to data sink 339 and decoded control information to controller / processor 340.

[0073] Memories 342 and 382 may store data and program codes for BS 102 and UE 104, respectively.

[0074] Scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.

[0075] In various aspects, BS 102 may be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 312, a scheduler 344, a memory 342, a transmit processor 320, a controller / processor 340, a TX MIMO processor 330, a transceiver 332a-332t, an antenna 334a-334t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 334a-334t, a transceiver 332a-332t, a RX MIMO detector 336, a controller / processor 340, a receive processor 338, a scheduler 344, a memory 342, and / or other aspects described herein.

[0076] In various aspects, the UE 104 may also be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 362, a memory 382, ​​a transmit processor 364, a controller / processor 380, a TX MIMO processor 366, a transceiver 354a-354t, an antenna 352a-352t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 352a-352t, a transceiver 354a-354t, a RX MIMO detector 356, a controller / processor 380, a receive processor 358, a memory 382, ​​and / or other aspects described herein.

[0077] In some aspects, the processor may be configured to perform various operations (such as those associated with the methods described herein) and send (output) data to or receive (obtain) data from another interface configured to send or receive data, respectively.

[0078] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes a method for use in a wireless communication network such as Figure 1 Various aspects of the data structure of the wireless communication network 100).

[0079] Specifically, Figure 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5G NR) frame structure, Figure 4B is a diagram 430 illustrating an example of a DL channel within a 5G subframe, Figure 4C is a diagram 450 illustrating an example of a second subframe within a 5G frame structure, and Figure 4D FIG480 is a diagram illustrating an example of UL channels within a 5G subframe.

[0080] Wireless communication networks can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single Carrier Frequency Division Multiplexing (SC-FDM) can be used to maximize the system bandwidth (e.g., Figure 4B and Figure 4D The RF (depicted) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0081] The wireless communication frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to either DL or UL. The wireless communication frame structure may also be time division duplex (TDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to both DL and UL.

[0082] exist Figure 4A and Figure 4C In the wireless communication frame structure, TDD is used, where D is DL, U is UL, and X is used flexibly between DL / UL. The UE can be configured with a time slot format (dynamically configured by DL control information (DCI) or semi-statically / statically configured by radio resource control (RRC) signaling) through the received time slot format indicator (SFI). In the depicted example, the 10ms frame is divided into 10 equally sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. The subframe may also include a micro-time slot, which generally has fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0083] In certain aspects, the number of slots within a subframe is based on the slot configuration and parameter set. For example, for slot configuration 0, different parameter sets (μ) 0 to 5 allow for 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different parameter sets 0 to 2 allow for 2, 4, and 8 slots per subframe, respectively. Thus, for slot configuration 0 and parameter set μ, there are 14 symbols / slot and 2μ slots / subframe. The subcarrier spacing and symbol length / duration are a function of the parameter set. The subcarrier spacing may be equal to 2 μ × 15kHz, where μ is parameter set 0 to 5. Thus, parameter set μ=0 has a subcarrier spacing of 15kHz, and parameter set μ=5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D An example is provided for slot configuration 0 with 14 symbols per slot and parameter set μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0084] like Figure 4A , Figure 4B , Figure 4C and Figure 4DAs depicted, a resource grid may be used to represent a frame structure. Each slot includes a resource block (RB) (also referred to as a physical RB (PRB)) extending, for example, over 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0085] like Figure 4A As illustrated, some of the REs carry data for the UE (eg, Figure 1 and Figure 3 The RS may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0086] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated.The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE Groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0087] The primary synchronization signal (PSS) may be in symbol 2 of a particular subframe of a frame. The PSS is transmitted by a UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identity.

[0088] The Secondary Synchronization Signal (SSS) may be in symbol 4 of a specific subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing.

[0089] Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block. The MIB provides the number of RBs in the system bandwidth and the system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information (such as system information blocks (SIBs)) that is not sent via the PBCH, and / or paging messages.

[0090] As in Figure 4CAs illustrated, some REs carry DMRS for channel estimation at the base station (indicated as R for a particular configuration, but other DMRS configurations are possible). The UE may send DMRS for PUCCH and DMRS for PUSCH. The PUSCH DMRS may be sent, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be sent in different configurations depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used. UE 104 may send a sounding reference signal (SRS). The SRS may be sent, for example, in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the comb structures in the comb structure. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0091] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0092] Introduction to non-terrestrial networks

[0093] In some cases, wireless communication networks (such as Figure 1 The communication in the wireless communication network 100 illustrated in FIG. 1 may be facilitated by one or more non-terrestrial (NT) devices. In such cases, the wireless communication network may be referred to as a NT network (NTN). NT devices may include devices such as space satellites, balloons, airships, airplanes, drones, unmanned aerial vehicles, etc., which may operate as BS 102.

[0094] Figure 5 An example of an NTN 500 including a satellite as an NTNBS 520 is illustrated, which may be similar to that for Figure 1 In some examples, NTN 500 can implement similar aspects as wireless communication network 100.

[0095] In one example, NTNBS 520 communicates with UE 104, such as by providing network coverage for NTN 500. For example, as discussed, NTNBS 520 can transmit using multiple beams, each beam covering a geographic area 510, which can be referred to as a coverage area of ​​the beam. Figure 5The NTNBS 520 is illustrated as transmitting using three beams covering three geographic areas 510a-510c. However, it should be noted that the NTNBS 520 may transmit using a fewer or greater number of beams. Furthermore, different beams may cover geographic areas of the same size or different sizes.

[0096] In some aspects, the NTNBS 520 uses different FCBs for beams covering adjacent coverage areas to avoid interference between devices near the edges of adjacent coverage areas. In some aspects, when in the coverage area of ​​the beam using the FCB, the FCB used by the UE 104 for uplink communication is the same as the FCB used by the NTNBS 520 for downlink communication. In some aspects, different FCBs can be used for uplink and downlink communications.

[0097] In certain aspects, the UE 104 communicates directly with the NTNBS 520, and the NTNBS 520 may communicate with other network entities of the NTN 500, such as via a gateway and / or another NT device.

[0098] As shown, a BS 102 of a TN, such as an embodiment of a wireless communication network 100, provides network coverage in a cell 110 that overlaps one or more coverage areas of one or more beams of an NTNBS 520. As shown, the cell 110 completely overlaps the coverage area 510a. However, it should be noted that the cell 110 may only partially overlap the coverage area of ​​the NTNBS 520. In addition, it should be noted that the cell 110 may partially and / or completely overlap multiple coverage areas of the NTNBS 520.

[0099] In some aspects, BS 102 can use the FCB on the downlink to communicate with UE 104 in cell 110. In some aspects, the FCB used by UE 104 for uplink communications is the same as the FCB used by BS 102 for downlink communications when in cell 110. In some aspects, different FCBs can be used for uplink and downlink communications.

[0100] As discussed, a network entity of NTN 500 (e.g., NTNBS 520 or another network entity) may communicate FCB allocation information of beams of NTNBS 520 with a network entity of network 100 (e.g., BS 102 or another network entity). Thus, the network entity of network 100 may configure BS 102 to use one or more FCBs in cell 110 that are not used by NTNBS 520 in the same geographic area as cell 110, thereby avoiding interference between NTN 500 and network 100.

[0101] Aspects related to spectrum sharing for NTN and terrestrial networks

[0102] As discussed, certain aspects herein provide for spectrum sharing for NTN and terrestrial networks.

[0103] Figure 6 A process flow 600 for spectrum sharing between NTN and TN is depicted. In some aspects, NTNBS 620 is for Figure 5 The depicted and described example of NTNBS 520, TNBS 602 is for Figure 1 The example of BS 102 described above and UEs 604a and 604b are for Figure 1 104 is an example of a UE 104 described herein. In addition, NT entity 630 is an example of a network entity of an NTN, and TN entity 640 is an example of a network entity of a TN. In some aspects, NT entity 630 is a separate device from NTNBS 620. In some aspects, NT entity 630 is NTNBS 620. In some aspects, TN entity 640 is a separate device from TNBS 602. In some aspects, TN entity 640 is TNBS 602. Although Figure 6 Two separate UEs are described, one communicating with NTNBS 620 and the other communicating with TNBS 602, but it should be noted that in some aspects, a single UE may communicate with both NTNBS 620 and TNBS 602. Thus, in some aspects, a single UE may perform operations for Figure 6 The actions of both UE 604a and UE 604b are discussed.

[0104] At 606, the NT entity 630 transmits the frequency allocation information to the TN entity 640. In some aspects, the NT entity 630 directly transmits the frequency allocation information to the TN entity 640. In some aspects, the NT entity 630 indirectly transmits the frequency allocation information to the TN entity 640, such as via a database 650 (e.g., a third-party database that is neither controlled by the network operator of the NTN nor by the TN). For example, the NT entity 630 may store the frequency allocation information in the database 650, and the TN entity 640 may retrieve the frequency allocation information from the database 650. The frequency allocation information may indicate information about which FCBs are used in which geographic locations in the NTN, as further discussed herein. In some aspects, the frequency allocation information indicates a first allocation pattern, as further discussed herein. In some aspects, the first allocation pattern identifies one or more corresponding FCBs for each of a plurality of beams of the NTNBS 620. For example, the first allocation pattern may identify a first FCB for a first beam in the plurality of beams.

[0105] In certain aspects, the frequency allocation information includes an index value mapped to a first allocation pattern, wherein a plurality of index values ​​map to a plurality of different allocation patterns.

[0106] At 608, the NT entity 630 transmits to the NTNBS 620 an indication of using one or more FCBs for one or more beams of the NTNBS 620. For example, in some aspects, the indication indicates using a first FCB for a first beam of the NTNBS 620.

[0107] At 610 , the NTNBS 620 indicates to the UE 604a , which may be a UE in the coverage area of ​​the first beam of the NTNBS 620 , to communicate using the first FCB.

[0108] At 612, the TN entity 640 transmits to the TNBS 602 an indication of one or more FCBs to be used for one or more cells of the TNBS 602. For example, in some aspects, the indication indicates to use a different FCB (e.g., a second FCB) for the first cell based on the coverage area of ​​the first cell overlapping the first beam. For example, based on receiving the frequency allocation information from the NT entity 630 at 606, the TN entity 640 may determine that the coverage area of ​​the first cell of the TNBS 602 overlaps the first beam of the NTNBS 620. In addition, the TN entity 640 may determine that the first FCB is used by the NTNBS 620 for communication via the first beam. Therefore, in order to avoid interfering with NTN communications, the TN entity 640 may determine to use a different FCB than the first FCB for communication in the first cell (e.g., and the FCB is different from any other FCB that the NT entity 630 may indicate to be used in a beam that overlaps the first cell). Since the coverage area of ​​the first cell overlaps the first beam, the frequency allocation information may also be referred to as instructing the NTNBS 620 to use the first FCB for communication in the first cell.

[0109] At 614 , the TNBS 602 indicates to the UE 604 b , which may be a UE in the coverage area of ​​the first cell of the TNBS 602 , an indication to communicate using the second FCB.

[0110] At 616, UE 604a communicates with NTNBS 620 (eg, receives downlink signals) using the first FCB indicated by NTNBS 620. At 618, UE 604b communicates with TNBS 602 (eg, receives downlink signals) using the second FCB indicated by TNBS 602.

[0111] Aspects related to frequency channel bands and allocation patterns

[0112] Fig. 7AAn example frequency band is illustrated that spans multiple example FCBs. Although this depiction includes four different FCBs, there may be fewer or more FCBs.

[0113] In some aspects, frequency band 710 is a contiguous subset of the spectrum that can be utilized by terrestrial networks and NTNs. For example, the spectrum that can be utilized by terrestrial networks and NTNs can be FR3 (6 GHz to 24 GHz), and frequency band 710 can be centered at 8 GHz with a bandwidth of 200 MHz.

[0114] Following the above example, the frequency band 710 can be subdivided into different continuous and non-overlapping FCBs, such as FCBs 712a-712d. In some examples, FCBs 712a-712d share the same bandwidth, such as 50 MHz. Alternatively, in some examples, the bandwidth of FCBs 712a-712d varies.

[0115] Figure 7B Two example allocation modes are illustrated, 720 and 730. Although this depiction includes two different allocation modes, fewer or more allocation modes may be specified using the depicted format.

[0116] For example, FCBs f1, f2, f3, and f4 may correspond to FCBs 712a-712d. For allocation patterns 720 and 730, each hexagon may correspond to a coverage area (e.g., a coverage area or cell of a beam) of a terrestrial network or NTN. For example, allocation pattern 720 may be an allocation pattern in an NTN, and allocation pattern 730 may be an allocation pattern in a terrestrial network.

[0117] In one example, hexagon 722 of allocation pattern 720 is the coverage area of ​​a first beam of NTNBS 620 , while hexagon 732 of allocation pattern 730 is a first cell of TNBS 602 .

[0118] In some aspects, cells of a TNBS such as TNBS 602 in the TN have a fixed relationship (e.g., a fixed geographic relationship) to the coverage area of ​​a beam of an NTNBS such as NTNBS 620 of the NTN. For example, NTNBS 620 may be geostationary, such as a high earth orbit satellite, so that the coverage area of ​​NTNBS 620 does not change with the rotation of the earth because the orbit of NTNBS 620 forms a geosynchronous relationship with the rotation of the earth. Therefore, in some aspects, NT entity 630 may semi-statically transmit frequency allocation information of the NTN to TN entity 640 because the frequency allocation of the beam of NTNBS 620 may not change with the rotation of the earth. The FCBs assigned to the beams of NTNBS 620 may change from time to time, such as due to other reasons, and therefore, NT entity 630 may transmit updated frequency allocation information to TN entity 640.

[0119] In some examples, the coverage areas of the multiple beams of NTNBS 620 correspond to and completely overlap the multiple cells of TNBS 602. For example, hexagon 722 and hexagon 732 may cover the same geographic area, and hexagon 724 and hexagon 734 may cover the same geographic area. Therefore, in order to minimize interference during communication in the geographic areas represented by hexagon 722 and hexagon 732, NTNBS 620 and TNBS 602 may be configured to communicate using different FCBs. For example, NTNBS 620 may communicate with a UE in hexagon 722 via a first FCB such as f2. In addition, TNBS 602 may communicate with another UE in hexagon 732 via a second FCB such as f4. Similarly, NTNBS 620 may communicate with a UE in hexagon 724 via f3, while TNBS 602 may communicate with another UE in hexagon 734 via f1.

[0120] Although not shown, as discussed, in some aspects, the coverage areas of the beams of NTNBS 620 and the cells of TNBS 602 may only partially overlap, such as due to size differences or location offsets (e.g., center offsets). For example, the coverage area of ​​a single beam may overlap with multiple cells, or the coverage area of ​​a single cell may overlap with multiple beams. In the case where multiple beams overlap with a single cell, TNBS 602 may be configured to use an FCB that is different from the FCB of each of the multiple beams.

[0121] In certain aspects, the allocation pattern is a repeating pattern such that the pattern can be spread over a larger geographic area.For example, the frequency allocation information can include an indication of an instance of a repeating pattern that is subsequently repeated over a larger geographic area than a single instance of the repeating pattern.

[0122] Aspects related to the changing relationship between beams and cells

[0123] Figure 8 A process flow 800 is depicted for spectrum sharing between an NTN and a TN. In some aspects, the NTNBS 820 is for Figure 5 The depicted and described example of NTNBS 520, TNBS 802 is for Figure 1 The example of BS 102 described above and UEs 804a and 804b are for Figure 1 104. In addition, NT entity 830 is an example of a network entity of an NTN, and TN entity 840 is an example of a network entity of a TN. In some aspects, NT entity 830 is a separate device from NTNBS 820. In some aspects, NT entity 830 is NTNBS 820. In some aspects, TN entity 840 is a separate device from TNBS 802. In some aspects, TN entity 840 is TNBS 802. Figure 8 While two separate UEs are described, one communicating with NTNBS 820 and the other communicating with TNBS 802, it should be noted that in certain aspects, a single UE may communicate with both NTNBS 820 and TNBS 802. Thus, in certain aspects, a single UE may perform operations for Figure 8 The actions of both UE 804a and UE 804b discussed. At 806, NT entity 830 transmits frequency allocation information to TN entity 840. In some aspects, NT entity 830 directly transmits frequency allocation information to TN entity 840. In some aspects, NT entity 830 indirectly transmits frequency allocation information to TN entity 840, such as via database 850 (e.g., a third-party database that is neither controlled by the network operator of the NTN nor by the TN).

[0124] The frequency allocation information may indicate information about which FCBs are used in which geographical locations in the NTN. In some aspects, the frequency allocation information further indicates the time periods in which the FCBs are used in the geographical locations in the NTN. For example, in some aspects, the cells of the TNBSs such as TNBS 802 in the TN have a changing relationship (e.g., a changing geographical relationship) to the coverage areas of the beams of the NTNBSs such as NTNBS 820 in the NTN. For example, the NTNBS 820 may be non-geostationary, such as a low earth orbit satellite, so that the coverage area of ​​the NTNBS 820 changes with the rotation of the earth, just as the orbit of the NTNBS 820. For example, the beams of the NTNBS 820 may move over time relative to the surface of the earth, so that during a first time period, the coverage area of ​​the first beam of the NTNBS 820 overlaps with the first cell of the TNBS 802. In addition, in this example, during a second time period, the coverage area of ​​the first beam no longer overlaps with the first cell, but the coverage area of ​​the second beam of the NTNBS 820 overlaps with the first cell. Therefore, the frequency allocation information may indicate this changing relationship. Therefore, based on the frequency allocation information, the TN entity 840 can determine which FCBs are used in the cell of the TNBS 802 during which time period, and thus indicate to the UEs in the cell to communicate using different FCBs during different time periods to avoid interference.

[0125] In certain aspects, the frequency allocation information indicates an allocation pattern such as discussed, and one or more of a trajectory or speed of the NTNBS 820. Based on such frequency allocation information, the TNBS 802 may determine which FCBs are used in which beams of the NTNBS 820, and further determine the varying coverage areas of each beam for the cells of the TN. For example, the TNBS 802 may determine that during a first time period, a first frequency channel band is used in a beam of the NTNBS 820 that overlaps with the cell of the TNBS 802, and during a second time period, a third frequency channel band is used in a beam of the NTNBS 820 that overlaps with the cell of the TNBS 802.

[0126] In some aspects, the frequency allocation information may indicate such a changing relationship in another suitable manner, such as explicitly indicating which FCBs are used in which geographic areas in which time periods. In some aspects, the frequency allocation information indicates a first allocation pattern for a first time period and a second allocation pattern for a second time period. In some aspects, the first allocation pattern or the second allocation pattern identifies one or more corresponding FCBs for each of a plurality of beams of the NTNBS 820. For example, the first allocation pattern may identify a first FCB for a first beam of a plurality of beams at a first duration, and the second allocation pattern may identify an FCB different from the first FCB (e.g., a third FCB) for a first beam of a plurality of beams at a second duration.

[0127] At 808, NT entity 830 transmits to NTNBS 820 an indication of using one or more FCBs for one or more beams of NTNBS 820. For example, in some aspects, the indication indicates using a first FCB for a first beam of NTNBS 820 and using a third FCB for a second beam of NTNBS 820.

[0128] At 810, prior to a first time period, NTNBS 820 indicates to UE 804a an indication to communicate using a first FCB, which may be a UE in a coverage area of ​​a first beam of NTNBS 820 during the first time period. UE 804a may be in a coverage area of ​​a second beam of NTNBS 820 during a second time period.

[0129] At 812, TN entity 840 transmits to TNBS 802 an indication of using one or more FCBs for one or more cells of TNBS 802 during one or more time periods. For example, the indication may indicate that TNBS 802 communicates in a first cell of TNBS 802 using a second FCB (e.g., a third FCB or another FCB different from the first FCB) during a first time period, and communicates in the first cell using a fourth FCB (e.g., the first FCB or another FCB different from the third FCB) during a second time period. For example, a coverage area of ​​a first beam of NTNBS 820 may overlap with a coverage area of ​​the first cell during the first time period, and a coverage area of ​​a second beam of NTNBS 820 may overlap with a coverage area of ​​the first cell during the second time period. Thus, the TN entity 840 may instruct the TNBS 802 to use one or more FCBs in the first cell during a first time period that are different from one or more FCBs used by the NTNBS 820 in one or more beams overlapping with the coverage area of ​​the first cell during the first time period, and may instruct the TNBS 802 to use one or more FCBs in the first cell during a second time period that are different from one or more FCBs used by the NTNBS 820 in one or more beams overlapping with the coverage area of ​​the first cell during the second time period.

[0130] For example, based on receiving the frequency allocation information from the NT entity 830 at 806, the TN entity 840 may determine that the coverage area of ​​the first cell of the TNBS 802 overlaps with the first beam of the NTNBS 820 during the first time period and overlaps with the second beam of the NTNBS 820 during the second time period. In addition, the TN entity 840 may determine that the first FCB is used by the NTNBS 820 for communication through the first beam, and the third FCB is used by the NTNBS 820 for communication through the second beam. Therefore, to avoid interfering with NTN communications during the first time period, the TN entity 840 may determine to use a different FCB than the first FCB for communication in the first cell during the first time period (e.g., and the FCB is different from any other FCB that the NT entity 830 may use in the beam that overlaps with the first cell during the first time period). Similarly, to avoid interfering with NTN communications during the second time period, the TN entity 840 may determine to use a different FCB than the third FCB for communication in the first cell during the second time period (e.g., and the FCB is different from any other FCB that the NT entity 830 may use in the beam that overlaps with the first cell during the second time period). Since the coverage area of ​​the first cell overlaps with the first beam, the frequency allocation information may also be referred to as instructing the NTNBS 820 to communicate in the first cell using the first FCB in the first time period and using the third FCB in the second time period.

[0131] At 814 , prior to the first time period, the TNBS 802 indicates to the UE 804 b , which may be a UE in the coverage area of ​​the first cell of the TNBS 802 , an indication to communicate using the second FCB.

[0132] At 816, UE 804a communicates with NTNBS 820 (e.g., receives downlink signals) using the first FCB indicated by NTNBS 820 during the first time period. At 818, UE 804b communicates with TNBS 802 (e.g., receives downlink signals) using the second FCB indicated by TNBS 802 during the first time period.

[0133] At 822, before the second time period (e.g., at the end of the first time period), the NTNBS 820 indicates to the UE 804a an indication to communicate using the third FCB. For example, during the second time period, the UE 804a may be in the coverage area of ​​the second beam of the NTNBS 820 instead of the first beam. In some examples, the third FCB is the same as the second FCB.

[0134] At 824, before the second time period (eg, at the end of the first time period), the TNBS 802 indicates to the UE 804b an indication to communicate using the fourth FCB.

[0135] At 826, UE 804a communicates with NTNBS 820 using the third FCB during the second time period. At 826, UE 804b communicates with TNBS 802 using the fourth FCB indicated by TNBS 802 during the second time period.
