[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Patent Application No. 17 / 662,601, filed on May 9, 2022, entitled “PERFORMING MEASUREMENTS OF FREQUENCIES ASSOCIATED WITH TERRESTRIALNETWORK CELLS” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of this patent application and is incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for performing measurements of frequencies associated with terrestrial network (TN) cells. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may 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 using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0032] During idle / inactive mode, the UE may perform measurements associated with multiple cells. The multiple cells may include terrestrial network (TN) cells and / or non-terrestrial network (NTN) cells. Compared with NTN cells, TN cells may have better performance (e.g., in terms of data rate), so frequencies associated with TN cells may have a higher priority than frequencies associated with NTN cells. For example, during idle / inactive mode, measurements of frequencies associated with TN cells may be prioritized relative to measurements of frequencies associated with NTN cells. The UE may be configured to always perform measurements of frequencies associated with TN cells, even when the signal strength associated with the NTN cells is relatively high, based at least in part on the higher priority of frequencies associated with TN cells. Even when the signal strength associated with the TN cells does not meet a threshold, the UE may periodically perform measurements of frequencies associated with TN cells.

[0033] One problem is that the area of ​​the NTN cell may be very large compared to the TN cell. The NTN cell may cover a relatively large area, some parts of which have TN cell coverage, but other parts do not have TN cell coverage. In some cases, the NTN cell may cover a large area without TN cell coverage. However, since the frequencies associated with the TN cell may have a higher priority than the frequencies associated with the NTN cell, when the UE is in one of the NTN cells, the UE may consume too much power due to unnecessary searches for frequencies associated with the TN cell. In other words, the UE may be located in an NTN cell that spans an area of ​​hundreds of miles and has no TN cell coverage, but the UE may still attempt to perform measurements of frequencies associated with the TN cell based at least in part on the higher priority of the frequencies associated with the TN cell, which may unnecessarily consume power at the UE.

[0034] In some aspects, the UE may receive information indicating frequencies associated with the TN cell from a network entity. The information may be a list of frequencies associated with the TN cell. The information may directly indicate the frequencies associated with the TN cell. Alternatively, the information may indirectly indicate the frequencies associated with the TN cell. In other words, the UE may use the information to determine the frequencies associated with the TN cell. When the UE is located within a TN cell, the UE may perform measurements of frequencies associated with the TN cell during an idle mode of the UE. The UE may receive TN cell coverage information indicating coordinate information associated with the TN cell from the network entity, and the UE may determine the position of the UE relative to the TN cell using the TN cell coverage information. When the UE's position is not in one of the TN cells, the UE may not perform measurements of frequencies associated with the TN cell, which may reduce power consumption at the UE.

[0035] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functions, or structures and functions in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0036] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0037] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0038] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d), a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The base station 110 is an entity that communicates with the UE 120. The base station 110 (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit receive point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0039] Base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femto cell (e.g., UE 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. In Figure 1 In the example shown, BS 110a may be a macro base station for macrocell 102a, BS 110b may be a pico base station for picocell 102b, and BS 110c may be a femto base station for femtocell 102c. A base station may support one or more (eg, three) cells.

[0040] In some aspects, the term "base station" (e.g., base station 110) or "network entity" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station" or "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (RU), a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network entity" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with base station 110). In some aspects, the term "base station" or "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographical location or in different geographical locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network entity" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network entity" may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network entity" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.

[0041] In some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected with each other and / or to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0042] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a base station 110 or a UE 120) and transmit transmissions of data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown, BS 110d (eg, a relay base station) may communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. A base station 110 that relays communications may be referred to as a relay station, relay base station, relay, or the like.

[0043] The wireless network 100 may be a heterogeneous network including different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0044] A network controller 130 may be coupled to or in communication with a set of base stations 110 and may provide coordination and control for the base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. The base stations 110 may also communicate directly with each other or indirectly via wireless or wired backhaul communication links.

[0045] UE 120 may be distributed throughout wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, 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, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate via a wireless medium.

[0046] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0047] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0048] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0049] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0050] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0051] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0052] In some aspects, a UE (e.g., UE 120) may include a communications manager 140. As described in greater detail elsewhere herein, the communications manager 140 may receive information indicating a frequency associated with a TN cell from a network entity and via a system information block (SIB), wherein the information includes one or more of a frequency priority, a frequency specific offset, or a cell specific offset; and during an idle mode of the UE, perform measurements of the frequency associated with the TN cell based at least in part on the UE's location being within the TN cell. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0053] In some aspects, as described in more detail elsewhere herein, the communication manager 140 may receive an indication of a frequency associated with a TN cell from a network entity; during an idle mode of the UE, attempt to perform measurements of the frequency associated with the TN cell; and disable subsequent attempts to perform measurements of the frequency associated with the TN cell based at least in part on a condition being satisfied, wherein the condition is associated with one or more of TN cell detection, a defined time period, or a UE location. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0054] In some aspects, as described in more detail elsewhere herein, the communication manager 140 may receive an indication of a frequency associated with a TN cell from a network entity; receive a cell coverage indication from the network entity, wherein the cell coverage indication includes information about a plurality of sub-areas within the cell; and during an idle mode of the UE, perform measurements of the frequency associated with the TN cell based at least in part on the cell coverage indication and a location of the UE within one of the plurality of sub-areas within the cell. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0055] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1Different than described.

[0056] Figure 2 1 is a diagram illustrating an example of base station 110 communicating with UE 120 in wireless network 200 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0057] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may 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 (CQI) received from the UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0058] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the base station 110 and / or other base stations 110, and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0059] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0060] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0061] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 7 to 14 ) or any aspect of any of the methods described herein.

[0062] At the base station 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232 shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 7 to 14 ) or any aspect of any of the methods described herein.

[0063] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the base station 110 may perform one or more techniques associated with performing measurements of frequencies associated with the TN cell, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Fig.11 Process 1100, Fig.12 The process 1200 Fig.13 1300 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for base station 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example Fig.11 Process 1100, Fig.12 The process 1200 Fig.13 The process 1300 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0064] In some aspects, a UE (e.g., UE 120) includes a means for receiving information indicating a frequency associated with a TN cell from a network entity and via a SIB, wherein the information includes one or more of a frequency priority, a frequency specific offset, or a cell specific offset; and / or a means for performing measurements of a frequency associated with a TN cell during an idle mode of the UE based at least in part on the UE's location being within the TN cell. The means for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0065] In some aspects, a UE (e.g., UE 120) includes: means for receiving an indication of a frequency associated with a TN cell from a network node; means for attempting to perform measurements of the frequency associated with the TN cell during an idle mode of the UE; and / or means for disabling subsequent attempts to perform measurements of the frequency associated with the TN cell based at least in part on a condition being satisfied, wherein the condition is associated with one or more of TN cell detection, a limited time period, or a UE location. Means for the UE to perform operations described herein may include, for example, one or more of: a communications 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.

[0066] In some aspects, a UE (e.g., UE 120) includes: means for receiving an indication of a frequency associated with a TN cell from a network node; means for receiving a cell coverage indication from a network entity, wherein the cell coverage indication includes information about a plurality of sub-areas within a cell; and / or means for performing measurements of a frequency associated with a TN cell during an idle mode of the UE based at least in part on the cell coverage indication and a location of the UE within one of the plurality of sub-areas within the cell. Means for the UE to perform operations described herein may include, for example, one or more of the following: communications manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0067] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0068] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0069] Figure 3 is a diagram illustrating an example of a decomposed base station architecture 300 according to the present disclosure.

[0070] The deployment of a communication system (such as a 5G NR system) may be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element or a network equipment (such as a base station (BS, e.g., base station 110), or one or more units (or one or more components) that perform base station functionality may be implemented in an aggregated or decomposed architecture. For example, a BS (such as a Node B (NB), an eNB, an NR BS, a 5G NNB, an access point (AP), a TRP, a cell, etc.) may be implemented as an aggregated base station (also referred to as a standalone BS or a monolithic BS) or a decomposed base station.

[0071] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit (e.g., a virtual centralized unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU)).

[0072] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an IAB network, an O-RAN (such as a network configuration sponsored by the O-RAN Alliance), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0073] Figure 3The decomposed base station architecture shown may include one or more CUs 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with a core network 320 through one or more decomposed base station units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via corresponding midhaul links, such as an F1 interface. The DU 330 may communicate with one or more RUs 340 via corresponding fronthaul links. The RU 340 may communicate with corresponding UEs 120 via one or more radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0074] Each of these units (e.g., CU 310, DU 330, RU 340), as well as near-RT RIC 325, non-RTRIC 315, and SMO framework 305 may include one or more interfaces, or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as 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 these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface that is configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally, a unit may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) that is configured to receive or send signals or both to one or more of the other units on a wireless transmission medium.

[0075] In some aspects, CU 310 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 as having an interface configured to communicate signals with other control functions hosted by CU 310. CU310 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 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0076] DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, DU 330 may host one or more of the following depending at least in part on a functional split such as that defined by 3GPP: 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.). In some aspects, DU 330 may further host one or more low PHY layers. Each layer (or module) may be implemented with an interface that is configured to communicate signals with other layers (and modules) hosted by DU 330 or with control functions hosted by CU 310.

[0077] The lower layer functionality may be implemented by one or more RUs 340. In some deployments, a RU 340 controlled by a DU 330 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 340 may be implemented to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable the implementation of the DU 330 and the CU 310 in a cloud-based RAN architecture (such as a vRAN architecture).

[0078] The SMO framework 305 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 305 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 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 390) 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 310, DU 330, RU 340, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some specific implementations, the SMO framework 305 may communicate directly with one or more RUs 340 via the O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305 .

[0079] The non-RT RIC 315 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 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 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 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0080] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of O1) or via creation of RAN management policies (such as A1 policies).

[0081] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different than described.

[0082] Figure 4 is a diagram illustrating an example of an NTN architecture 400 according to the present disclosure.

[0083] like Figure 4 As shown, a UE 402 in connected mode may communicate with a serving network entity 408 via a serving satellite 404 in the NTN architecture 400. The UE 402 may send an uplink transmission to the serving satellite 404. The serving satellite 404 may relay the uplink transmission to the serving network entity 408 via a serving gateway 406. The serving network entity 408 may send a downlink transmission to the serving satellite 404 via the serving gateway 406. The serving satellite 404 may relay the downlink transmission to the UE 402. The link between the UE 402 and the serving satellite 404 may be a serving link, and the link between the serving satellite 404 and the serving gateway 406 may be a feeding link.

[0084] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 Different than described.

[0085] Figure 5A and Figure 5B are diagrams illustrating examples of NTN architectures 500 , 510 , respectively, for non-geostationary satellites according to the present disclosure.

[0086] A UE configured to operate in an NTN architecture (or NTN configuration or NTN deployment) may be equipped with a global navigation satellite system (GNSS). The UE may be configured with measurement and mobility related parameters based at least in part on an assumption that the UE is located at the center of a beam coverage area (eg, the center of a cell).

[0087] like Figure 5A As shown, for non-geostationary satellites, the NTN architecture 500 may be associated with a quasi-ground-fixed cell deployment. For quasi-ground-fixed cell deployment, the beam coverage area (or cell) may be ground-fixed, in which case the beam pointing mechanism may compensate for the mobility of the non-geostationary satellite. In other words, even if the satellite may move over time, the beam coverage area may remain fixed on the earth based at least in part on the beam pointing mechanism. The beam coverage area that may be associated with the cell may not move as the non-geostationary satellite moves above the earth. The beam pointing mechanism may be associated with a mechanical or electronic steering feature that allows the non-geostationary satellite to steer the beam coverage area as the non-geostationary satellite moves above the earth.

[0088] like Figure 5B As shown, for non-geostationary satellites, NTN architecture 510 can be associated with geostationary cell deployment. For geostationary cell deployment, the beam coverage area can move above the earth with the movement of the non-geostationary satellite. The beam coverage area can move above the earth with the non-geostationary satellite.

[0089] As indicated above, Figure 5A and Figure 5B are provided as examples. Other examples can be found in the Figure 5A and Figure 5B Different from what is described.

[0090] During RRC idle / inactive mode, the UE may perform measurements associated with multiple cells (e.g., serving cells and / or neighboring cells). The UE may monitor a control channel during RRC idle / inactive mode. The UE may receive control signals from multiple cells via the control channel, and the UE may determine the measurement results based at least in part on the control signals. The UE may select another cell from the multiple cells based at least in part on the measurement results, and then perform registration with the selected cell. For example, the UE may determine that the second cell is associated with a higher measured signal strength than the first cell (e.g., serving cell), and then the UE may perform registration with the second cell. Based at least in part on cell reselection, the UE may connect to the second cell and disconnect from the first cell.

[0091] The multiple cells may include TN cells and / or NTN cells. For example, the serving cell may be a TN cell, and the neighboring cell may be an NTN cell, and vice versa. The TN cell may have better performance (e.g., in terms of data rate) than the NTN cell, and thus the frequency associated with the TN cell may have a higher priority than the frequency associated with the NTN cell. For example, during RRC idle / inactive mode, the measurement of the frequency associated with the TN cell may be prioritized relative to the measurement of the frequency associated with the NTN cell. The UE may be configured to always perform the measurement of the frequency associated with the TN cell, even when the signal strength associated with the NTN cell is relatively high, based at least in part on the higher priority of the frequency associated with the TN cell. The UE may also periodically perform the measurement of the frequency associated with the TN cell even when the signal strength associated with the NTN cell does not meet the threshold.

[0092] Compared with TN cells, the area of ​​NTN cells may be very large. For example, the area of ​​NTN cells may be hundreds of miles, while the area of ​​TN cells may be several miles. NTN cells may cover relatively large areas with different landscapes (e.g., urban areas, oceans, mountains), some parts of which have TN cell coverage, but other parts do not have TN cell coverage. In some cases, NTN cells may cover large areas without TN cell coverage. However, since the frequencies associated with TN cells may have a higher priority than the frequencies associated with NTN cells, when the UE is in one of the NTN cells, the UE may consume too much power due to unnecessary searches for frequencies associated with TN cells. In other words, the UE may be located in an NTN cell across an area of ​​hundreds of miles and without TN cell coverage, but the UE may still attempt to perform measurements of frequencies associated with the TN cells based at least in part on the higher priority of the frequencies associated with the TN cells, which may unnecessarily consume power at the UE.

[0093] Figure 6 is a diagram illustrating an example of a TN cell search 600 according to the present disclosure.

[0094] like Figure 6As shown, UE 602 may be located within an NTN cell. A portion of the NTN cell may be associated with TN cell coverage, while other portions of the NTN cell may not be associated with TN cell coverage. Since the diameter of an NTN cell may be hundreds of miles, the portion of the NTN cell that does not have TN cell coverage may be an ocean, a mountain range, or other remote area. However, due to the higher priority of frequencies associated with TN cells relative to frequencies associated with NTN cells, when UE 602 is located within an NTN cell, UE 602 may still search for frequencies associated with TN cells, which may unnecessarily consume power at UE 602. In other words, when outside of TN cell coverage, UE 602 may still search for TN cells.

[0095] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 Different than described.

[0096] In various aspects of the techniques and apparatus described herein, a UE may receive information indicating frequencies associated with a TN cell from a network entity and via a SIB. The information may be a list of frequencies associated with a TN cell. The UE may perform measurements of the frequencies associated with the TN cell based at least in part on the location of the UE within the TN cell during an idle mode of the UE. The UE may receive TN cell coverage information indicating coordinate information associated with a TN cell from a network entity, wherein the location of the UE relative to the TN cell may be based at least in part on the TN cell coverage information. In some aspects, the information indicating frequencies associated with a TN cell may enable the UE to determine which frequencies are associated with the TN cell and which frequencies are associated with an NTN cell. When the location of the UE is not in one of the TN cells, the UE may not perform measurements of frequencies associated with the TN cell, which may reduce power consumption at the UE.

[0097] Figure 7 is a diagram illustrating an example associated with performing measurements of frequencies associated with a TN cell 700 according to the present disclosure. Figure 7 As shown, communications may occur between a UE 720 (eg, UE 120) and a network entity 710 (eg, base station 110). In some aspects, UE 720 and network entity 710 may be included in a wireless network, such as wireless network 100.

[0098] In some aspects, UE 720 may receive TN cell coverage information from network entity 710. TN cell coverage information may indicate TN cell coordinates, TN cell radius and / or TN cell center. UE 720 may determine whether the current location of UE 720 is within the TN cell based at least in part on the TN cell coverage information. In other words, UE 720 may determine whether UE 720 is within the coverage of the TN cell. When UE 720 is within the TN cell, UE 720 may search for frequencies associated with the TN cell. When UE 720 is not within the TN cell (e.g., UE 720 is within the NTN cell), UE 720 may not search for frequencies associated with the TN cell, which may save power consumption at UE 720. UE 720 may use various mechanisms to determine which frequencies are associated with the TN cell, as described in further detail below.

[0099] As shown in reference numeral 702, UE 720 may receive information indicating frequencies associated with TN cells from network entity 710 and via SIB, wherein the information may include a priority of the frequency, a frequency-specific offset, and / or a cell-specific offset. The information may directly indicate a frequency associated with the TN cell. Alternatively, the information may indirectly indicate a frequency associated with the TN cell. The frequency may be inter-frequency and / or intra-frequency. In some aspects, the SIB may be a SIB type 3 (SIB3) or a SIB type 4 (SIB4), and the information may be a list of frequencies associated with the TN cell.

[0100] In some aspects, the UE 720 may receive a SIB, such as SIB3 or SIB4, from the network entity 710. The SIB3 or SIB4 may indicate a frequency list, which may include frequencies associated with a TN cell and / or frequencies associated with an NTN cell. The frequency list may include intra-frequency and / or inter-frequency. For example, a TN cell indication may be added to an intra-frequency and / or inter-frequency list in the SIB3 or SIB4. Thus, the UE 720 is able to determine which frequencies are associated with the TN cell.

[0101] In some aspects, the UE 720 may receive a SIB from the network entity 710, wherein the SIB may be an NTN-specific SIB. The information may indicate a satellite list and a frequency index. The frequency corresponding to the satellite in the satellite list from the frequency index may indicate a frequency associated with the NTN cell. The frequency associated with the TN cell may be derived at least in part based on the frequency associated with the NTN cell.

[0102] In some aspects, the UE 720 may receive an NTN-specific SIB (e.g., SIBxy) from the network entity 710. The NTN-specific SIB may indicate NTN-specific information, such as a satellite list and / or ephemeris information. The satellite list may be a list of neighboring satellites. When the satellite list is provided in the NTN-specific SIB, the NTN-specific SIB may also indicate the index of the frequency currently being broadcast from SIB3 or SIB4. The index of the frequency may be for intra-frequency and / or inter-frequency. The UE 720 may compare the satellite list with the index of the frequency, and based at least in part on the comparison, the UE 720 may determine which frequencies (e.g., from those frequencies broadcast from SIB3 or SIB4) are associated with the NTN cell (or satellite) and which frequencies are not associated with the NTN cell. Frequencies not associated with the NTN cell may be associated with the TN cell. Therefore, the UE 720 is able to determine which frequencies are associated with the TN cell.

[0103] In some aspects, UE 720 may receive the information, which may be a list of frequencies and corresponding priority values, from network entity 710. Frequencies from the list of frequencies having priority values ​​that satisfy a threshold may correspond to frequencies associated with a TN cell.

[0104] In some aspects, the UE 720 may receive a SIB indicating a list of frequencies from the network entity 710, wherein the frequencies may be associated with a TN cell or an NTN cell based at least in part on a frequency priority. In other words, an existing frequency priority may be used to indicate a TN cell. As an example, the highest priority value (e.g., a priority value of 7, from a range of 1-7) may never be assigned to a frequency associated with an NTN cell. Instead, the highest priority value may be assigned (e.g., always assigned) to a frequency associated with a TN cell. As another example, a range of priority values ​​(e.g., priority values ​​6 and 7) may be assigned (e.g., always assigned) to a frequency associated with a TN cell (or multiple TN cells). Therefore, based on the priority associated with a particular frequency, the UE 720 is able to determine whether the frequency is associated with a TN cell.

[0105] In some aspects, the UE 720 may receive information from the network entity 710, where the information may be a list of frequencies and corresponding sub-priority values. The sub-priority may be an additional layer of priority information. The sub-priority value may be used for frequencies associated with TN cells. The sub-priority value may not be used for frequencies associated with non-terrestrial network cells.

[0106] In some aspects, the frequency priority may be a sub-priority, where the sub-priority may apply to frequencies associated with TN cells. The sub-priority may not apply to frequencies associated with NTN cells. Sub-priorities such as a cell reselection sub-priority (e.g., CellReselectionSubPriority) may only apply to frequencies associated with TN cells, and frequencies associated with NTN cells may not use sub-priorities.

[0107] In some aspects, the UE 720 may receive information from the network entity 710, where the information may be a list of frequencies and corresponding offset ranges. The offset ranges may correspond to frequency-specific offsets or cell-specific offsets. The offset ranges that meet the threshold may correspond to frequencies associated with a TN cell.

[0108] In some aspects, the UE 720 may receive a SIB (e.g., Q-OffsetRange) indicating an offset range from the network entity 710, which may indicate a frequency-specific offset or a cell-specific offset. The offset range may be used to indicate a frequency associated with a TN cell. For example, some range values ​​such as a large positive offset (e.g., 20 dB, 22 dB, or 24 dB) may not be used for frequencies associated with an NTN cell (or not for an NTN cell). Instead, such a large positive offset may only be used for frequencies associated with a TN cell. Therefore, based on the offset range, the UE 720 is able to determine whether certain frequencies are associated with a TN cell.

[0109] In some aspects, UE 720 may receive information from network entity 710, where the information may indicate a RAT associated with the TN cell. The measurement of the frequency associated with the TN cell may be based at least in part on the RAT associated with the TN cell supported by UE 720.

[0110] In some aspects, the SIB indicating the frequency associated with the TN cell may also include an indication of the TN cell RAT type. Different TN cells may be associated with different types of RATs, such as NR, Universal Terrestrial Radio Access (UTRA), or Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA). The UE 720 with NTN capability may also support LTE and Global System for Mobile Communications (GSM). The indication of the TN cell RAT type may indicate whether the TN cell is NR. When the UE 720 does not support LTE / GSM, when the frequency associated with the TN cell is not an NR frequency, the UE 720 may not search for a frequency associated with a TN cell having a higher priority. In other words, even when the frequency associated with the TN cell has a higher priority, when the frequency is a non-NR frequency and the UE 720 does not support a non-NR RAT (e.g., LTE / GSM), the UE 720 may not search for such a frequency, which may save power at the UE 720. For example, when UE 720 supports standalone NR, when the coverage broadcast in the SIB is only for LTE TN cells, UE 720 does not need to attempt to measure or detect frequencies associated with TN cells.

[0111] As indicated by reference numeral 704, UE 720 may perform measurements of frequencies associated with a TN cell during an idle mode of UE 720. UE 720 may perform measurements of frequencies associated with a TN cell based at least in part on the position of UE 720 being within the TN cell. The UE may receive TN cell coverage information indicating coordinate information associated with the TN cell from network entity 710. The position of UE 720 relative to the TN cell may be based at least in part on the TN cell coverage information. When the position of UE 720 is within the TN cell, UE 720 may perform measurements of frequencies associated with the TN cell. When the position of UE 720 is not within the TN cell (e.g., within the NTN cell), UE 720 may not perform measurements of frequencies associated with the TN cell.

[0112] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 Different than described.

[0113] Figure 8 8 is a diagram illustrating an example associated with performing measurements of frequencies associated with a TN cell 800 according to the present disclosure. Figure 8 As shown, communications may occur between a UE 820 (e.g., UE 120) and a network entity 810 (e.g., base station 110). In some aspects, UE 820 and network entity 810 may be included in a wireless network, such as wireless network 100.

[0114] As indicated by reference numeral 802, UE 820 may receive an indication of frequencies associated with a TN cell from network entity 810. UE 820 may receive a SIB including the indication of frequencies associated with the TN cell. For example, the SIB may include a list of frequencies associated with the TN cell.

[0115] In some aspects, the UE 820 may receive information indicating a frequency associated with the TN cell. In other words, the UE 820 may determine the frequency associated with the TN cell based at least in part on the information. The UE 820 may receive a satellite list and a frequency index, wherein a frequency corresponding to a satellite in the satellite list from the frequency index may indicate a frequency associated with the NTN cell, and the frequency associated with the TN cell may be derived based at least in part on the frequency associated with the NTN cell. The UE 820 may receive a frequency list and corresponding priority values, wherein a frequency from the frequency list having a priority value that satisfies a threshold may correspond to a frequency associated with the TN cell. The UE 820 may receive a frequency list and corresponding sub-priority values, wherein the sub-priority value may be used for a frequency associated with the TN cell, and the sub-priority value may not be used for a frequency associated with the NTN cell. The UE 820 may receive a frequency list and corresponding offset ranges, wherein the offset ranges may correspond to frequency-specific offsets or cell-specific offsets, and the offset ranges that satisfy the threshold may correspond to frequencies associated with the TN cell.

[0116] As shown by reference numeral 804, UE 820 may attempt to perform measurements of frequencies associated with a TN cell during an idle mode of UE 820. UE 820 may attempt to perform measurements of frequencies associated with the TN cell based at least in part on whether a synchronization signal block (SSB) is detected within the frequency associated with the TN cell. When UE 820 detects an SSB within the frequency associated with the TN cell, UE 820 may perform measurements of the SSB. When UE 820 does not detect an SSB within the frequency associated with the TN cell (e.g., does not detect a TN cell), UE 820 may not be able to perform measurements of the SSB.

[0117] As shown in reference numeral 806, UE 820 may disable subsequent attempts to perform measurements of frequencies associated with TN cells based at least in part on a condition being met, wherein the condition may be associated with TN cell detection, a defined time period, and / or UE location. UE 820 may disable subsequent attempts based at least in part on not detecting a TN cell after a defined number of attempts. UE 820 may disable subsequent attempts based at least in part on not detecting a TN cell after a defined number of discontinuous reception (DRX) cycles. UE 820 may disable subsequent attempts within a defined time period. UE 820 may disable subsequent attempts until UE 820 moves a distance that satisfies a threshold. When the UE location is at a distance that satisfies a threshold from the initial location, UE 820 may disable subsequent attempts. UE 820 may retry to perform measurements of frequencies associated with TN cells based at least in part on a second condition being met, wherein the second condition may be met based at least in part on the expiration of a defined time period or the UE 820 moving a distance that satisfies a threshold.

[0118] In some aspects, the UE 820 may perform measurements of frequencies associated with the TN cell based at least in part on a relaxed TN cell search procedure. The relaxed TN cell search procedure may involve disabling subsequent attempts to perform measurements of frequencies associated with the TN cell, regardless of the frequencies associated with the TN cell being associated with a high priority.

[0119] In some aspects, the UE 820 may not receive TN cell coverage information from the network entity 810, but the UE 820 may receive a SIB indicating a frequency list, which may include frequencies associated with the TN cell. In this case, the UE 820 may implement a relaxed search process, which may save power at the UE. When the frequencies associated with the TN cell are indicated by the SIB, the UE 820 may implement a relaxed search process for the frequencies associated with the TN cell (or for the TN cell) but not for the frequencies associated with the NTN cell.

[0120] In some aspects, during the relaxed search process, the UE 820 may attempt to detect an SSB in a frequency associated with a TN cell. After a certain number of attempts or after a certain number of DRX cycles, when a TN cell is not detected in the frequency, the UE 820 may disable the search for the frequency. In other words, when the number of search instances in which the UE 820 cannot detect an SSB in a frequency associated with a TN cell satisfies a threshold, the UE 820 may disable the search for the frequency associated with the TN cell. By disabling the search for a frequency associated with a TN cell, the UE 820 may relax the higher priority frequency measurement rules even though the frequency may be associated with a higher priority.

[0121] In some aspects, the UE 820 may determine to restart searching for frequencies associated with the TN cell after a predefined time period. The predefined time period may be the number of DRX cycles. In other words, after the time period expires, the UE 820 may restart searching for frequencies associated with the TN cell, and if the frequency is not found after a certain number of search attempts, the UE 820 may again disable searching for the frequency. In some aspects, the UE 820 may determine to restart searching for frequencies associated with the TN cell (e.g., resume higher priority frequency search) based at least in part on a distance threshold criterion. For example, when the UE 820 moves a distance threshold that satisfies the distance threshold criterion, the UE 820 may restart searching for frequencies associated with the TN cell. In other words, unless the UE 820 moves the distance threshold, the UE 820 may not measure frequencies associated with the TN cell.

[0122] In some aspects, the UE 820 may implement a relaxed search procedure for the current highest priority frequency associated with the TN cell, and the relaxed search procedure may not be applied to lower priority frequencies associated with the TN cell. In some aspects, an equal or lower priority frequency search based on the serving cell RSRP may be used for higher priority frequencies associated with the TN cell. In addition, for cell reselection when the measurement associated with the serving cell no longer meets the threshold, the UE 820 may search for higher priority frequencies associated with the TN cell.

[0123] As indicated above, Figure 8 are provided as examples. Other examples can be found in the Figure 8 Different than described.

[0124] Fig. 9 9 is a diagram illustrating an example associated with performing measurements of frequencies associated with a TN cell 900 according to the present disclosure. Fig. 9 As shown, communications may occur between a UE 920 (eg, UE 120) and a network entity 910 (eg, base station 110). In some aspects, UE 920 and network entity 910 may be included in a wireless network (such as wireless network 100).

[0125] As indicated by reference numeral 902, UE 920 may receive an indication of frequencies associated with a TN cell from network entity 910. UE 920 may receive a SIB including the indication of frequencies associated with the TN cell. For example, the SIB may include a list of frequencies associated with the TN cell.

[0126] As indicated by reference numeral 904, UE 920 may receive a cell coverage indication from network entity 910. UE 920 may receive the cell coverage indication in system information via a broadcast from network entity 910. The cell coverage indication may include information about a plurality of sub-areas within a cell. The information about the plurality of sub-areas within a cell may be a bitmap, wherein each bit of the bitmap may be associated with a particular sub-area among the plurality of sub-areas. The cell coverage indication may indicate a cell reference point of the cell and a radius of the cell. The cell coverage indication may indicate a plurality of sub-areas within a cell using one or more directions, one or more angles and / or one or more area identifiers.

[0127] In some aspects, the cell coverage indication may indicate, for each of the plurality of sub-areas, whether to enable the measurement of the frequency associated with the TN cell. For example, for a particular sub-area, when the measurement of the frequency associated with the TN cell is not enabled, the cell coverage indication may indicate a value of "0", or when the measurement of the frequency associated with the TN cell is enabled, the cell coverage indication may indicate a value of "1". The cell coverage indication may include information about a plurality of sub-areas within the cell. The cell coverage indication may indicate, for each of the plurality of sub-areas, whether to disable the measurement of the frequency associated with the TN cell. In some aspects, the UE 920 may discard the cell coverage indication after the UE 920 is no longer associated with the cell.

[0128] In some aspects, the UE 920 may receive a cell coverage indication from the network entity 910. The cell coverage indication may divide the cell coverage area into multiple sub-areas (or multiple parts). The multiple sub-areas may be indicated by different angles and / or area identifiers. The UE 920 may receive the cell coverage indication after camping on a cell associated with the cell coverage indication. The UE 920 may receive the cell coverage indication in the system information via a broadcast. The cell coverage indication may indicate a reference point (or center) of the cell and a radius associated with the cell. The cell coverage indication may indicate multiple sub-areas (or directions) associated with the cell. The cell coverage indication may indicate whether TN cell search should be enabled or disabled for each sub-area. "TN cell search" may refer to a search for frequencies associated with a TN cell. The UE 920 may perform a TN cell search (e.g., measure frequencies associated with a TN cell) based at least in part on the cell coverage indication. The cell coverage indication may be cell-specific, and when the UE 920 is no longer camped in the cell, the UE 920 may discard the cell coverage indication.

[0129] For example, the cell coverage indication may include a bitmap (e.g., a 4-bit bitmap) to indicate four parts of the cell, such as a northwest (NW) part, a northeast part (NE), a southwest (SW) part, and a southeast (SE) part. For each of the NW part, the NE part, the SW part, and the SE part, the bitmap may indicate whether the TN cell search should be enabled or disabled. For example, the bitmap may indicate two sub-areas where the TN cell search should be enabled and three sub-areas where the TN cell search should be disabled. For another example, the cell coverage indication may include a list of area identifiers corresponding to areas where the TN cell search is disabled, wherein the cell coverage indication may be provided to the UE 920 by the network entity 910 in a system information message or in a UE-specific dedicated signal.

[0130] In some aspects, the UE 920 may receive an indication from the network entity 910 of inter-RAT information providing coverage to the UE 920, wherein the inter-RAT information may include information about the NR RAT, the LTE RAT, and / or the GSM RAT. The UE 920 may select coverage other than NR (e.g., LTE or GSM) using a priority scheme, wherein the priority scheme may be signaled by the network entity 910 to the UE.

[0131] As indicated by reference numeral 906, the UE 920 may perform measurements of frequencies associated with the TN cell based at least in part on the cell coverage indication and the location of the UE 920 within one of the plurality of sub-areas within the cell during an idle mode of the UE 920. The UE 920 may use the cell coverage indication to determine that the location of the UE 920 is within one of the plurality of sub-areas within the cell that enables performing measurements of frequencies associated with the TN cell, and based at least in part on the determination, the UE 920 may perform measurements of frequencies associated with the TN cell.

[0132] As indicated above, Fig. 9 are provided as examples. Other examples can be found in the Fig. 9 Different than described.

[0133] Fig.10 is a diagram illustrating an example associated with performing measurement of a frequency associated with a TN cell 1000 according to the present disclosure.

[0134] like Fig.10As shown, the cell coverage indication may divide the cell coverage area into a plurality of parts. The cell coverage indication may indicate a reference point (or center) of the cell and a radius associated with the cell. The reference point may be associated with coordinate information (such as longitude and latitude). The cell coverage indication may indicate a plurality of parts associated with the cell. For example, the cell coverage indication may indicate that the cell is divided into an NW part, a NE part, a SW part, and a SE part. In addition, for each part, the cell coverage indication may indicate whether the TN cell search should be enabled or disabled. For a first UE 1002 (e.g., UE1) within a specific part (e.g., SW part) of the cell coverage area, the cell coverage indication may indicate that the TN cell search should be disabled due to the absence of a TN cell in the part of the cell coverage area. The first UE 1002 may be associated with a position (e.g., longitude and latitude) within a specific part of the cell coverage area. A second UE 1004 (e.g., UE2) outside the cell coverage area may perform a TN cell search.

[0135] As indicated above, Fig.10 are provided as examples. Other examples can be found in the Fig.10 Different than described.

[0136] Fig.11 is a diagram illustrating an example process 1100, performed, for example, by a UE, according to the present disclosure. Example process 1100 is an example in which a UE (eg, UE 120) performs operations associated with performing measurements of frequencies associated with a TN cell.

[0137] like Fig.11 As shown, in some aspects, process 1100 may include receiving information indicating a frequency associated with a TN cell from a network entity and via a SIB, wherein the information includes one or more of a frequency priority, a frequency specific offset, or a cell specific offset (block 1110). For example, a UE (e.g., using Fig.14 The communication manager 140 and / or receiving component 1402 depicted in the figure can receive information indicating a frequency associated with a terrestrial network (TN) cell from a network entity and via a system information block (SIB), wherein the information includes one or more of a frequency priority, a frequency specific offset, or a cell specific offset, as described above.

[0138] like Fig.11 As further shown, in some aspects, process 1100 may include, during an idle mode of the UE, performing measurements of frequencies associated with the TN cell based at least in part on the UE's location being within the TN cell (block 1120). Fig.14The communications manager 140 and / or measurement component 1408 depicted in FIG. 1404 may perform measurements of frequencies associated with a TN cell during an idle mode of the UE based at least in part on the UE's location being within the TN cell, as described above.

[0139] Process 1100 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0140] In a first aspect, process 1100 includes receiving, from a network entity, TN cell coverage information indicating coordinate information associated with a TN cell, wherein a location of a UE relative to the TN cell is based at least in part on the TN cell coverage information.

[0141] In a second aspect, alone or in combination with the first aspect, the SIB is an NTN-specific SIB, wherein the information indicates a satellite list and a frequency index, wherein a frequency corresponding to a satellite in the satellite list from the frequency index indicates a frequency associated with the NTN cell, and the frequency associated with the TN cell is derived at least in part based on the frequency associated with the NTN cell.

[0142] In a third aspect, alone or in combination with one or more of the first and second aspects, the SIB is SIB3 or SIB4, and the information is a list of frequencies associated with the TN cell.

[0143] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the information is a frequency list and corresponding priority values, and the frequencies from the frequency list having priority values ​​satisfying the threshold correspond to the frequencies associated with the TN cell.

[0144] In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the information is a list of frequencies and corresponding priority values, wherein sub-priority values ​​are used for frequencies associated with TN cells and sub-priority values ​​are not used for frequencies associated with non-terrestrial network cells.

[0145] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the information is a frequency list and corresponding offset ranges, wherein the offset ranges correspond to frequency-specific offsets or cell-specific offsets, and the offset ranges that meet the threshold correspond to frequencies associated with the TN cell.

[0146] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the information indicates a RAT associated with the TN cell, and the measurement of the frequency associated with the TN cell is at least partially based on the RAT associated with the TN cell supported by the UE.

[0147] although Fig.11 An example block diagram of process 1100 is shown, but in some aspects, process 1100 may include Fig.11 Additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 1100. Additionally or alternatively, two or more blocks of the blocks of process 1100 may be performed in parallel.

[0148] Fig.12 is a diagram illustrating an example process 1200 performed, for example, by a UE according to the present disclosure. Example process 1200 is an example in which a UE (eg, UE 120) performs operations associated with performing measurements of frequencies associated with a TN cell.

[0149] like Fig.12 As shown, in some aspects, process 1200 may include receiving an indication of a frequency associated with a TN cell from a network entity (block 1210). For example, a UE (e.g., using Fig.14 The communications manager 140 and / or receiving component 1402 depicted in FIG. 1404 may receive an indication of a frequency associated with a TN cell from a network entity, as described above.

[0150] like Fig.12 As further shown, in some aspects, process 1200 may include attempting to perform measurements of frequencies associated with a TN cell during an idle mode of the UE (block 1220). Fig.14 The communications manager 140 and / or measurement component 1408 depicted in FIG. 1404 may attempt to perform measurements of frequencies associated with TN cells during an idle mode of the UE, as described above.

[0151] like Fig.12 As further shown, in some aspects, process 1200 may include disabling subsequent attempts to perform measurements on frequencies associated with a TN cell based at least in part on a condition being satisfied, wherein the condition is associated with one or more of TN cell detection, a defined time period, or a UE location (block 1230). Fig.14 The communication manager 140 and / or measurement component 1408 depicted in FIG. 1 may disable subsequent attempts to perform measurements of frequencies associated with a TN cell based at least in part on a condition being satisfied, wherein the condition is associated with one or more of TN cell detection, a defined time period, or a UE location, as described above.

[0152] Process 1200 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0153] In a first aspect, attempting to perform measurements of a frequency associated with the TN cell is based at least in part on whether an SSB is detected within the frequency associated with the TN cell.

[0154] In a second aspect, either alone or in combination with the first aspect, process 1200 includes disabling subsequent attempts based at least in part on failure to detect a TN cell after a defined number of attempts.

[0155] In a third aspect, alone or in combination with one or more of the first and second aspects, process 1200 includes disabling subsequent attempts based at least in part on not detecting a TN cell after a defined number of DRX cycles.

[0156] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, process 1200 includes disabling subsequent attempts for a defined period of time.

[0157] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 1200 includes disabling subsequent attempts until the UE moves a distance that satisfies a threshold.

[0158] In a sixth aspect, either alone or in combination with one or more of aspects 1 to 5, process 1200 includes reattempting to perform measurements of a frequency associated with a TN cell based at least in part on a second condition being satisfied, wherein the second condition is satisfied based at least in part on expiration of a defined time period or the UE moving a distance satisfying a threshold to a UE location.

[0159] In a seventh aspect, either alone or in combination with one or more of aspects 1 to 6, process 1200 includes performing measurements of frequencies associated with a TN cell based at least in part on a relaxed TN cell search process, wherein the relaxed TN cell search process involves disabling subsequent attempts to perform measurements of frequencies associated with the TN cell, regardless of whether the frequencies associated with the TN cell are associated with a high priority.

[0160] although Fig.12 An example block diagram of process 1200 is shown, but in some aspects, process 1200 may include Fig.12 Additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 1200. Additionally or alternatively, two or more blocks of the blocks of process 1200 may be performed in parallel.

[0161] Fig.13 is a diagram illustrating an example process 1300 performed, for example, by a UE according to the present disclosure. Example process 1300 is an example in which a UE (eg, UE 120) performs operations associated with performing measurements of frequencies associated with a TN cell.

[0162] like Fig.13 As shown, in some aspects, process 1300 may include receiving an indication of a frequency associated with a TN cell from a network entity (block 1310). For example, a UE (e.g., using Fig.14 The communications manager 140 and / or receiving component 1402 depicted in FIG. 1404 may receive an indication of a frequency associated with a TN cell from a network entity, as described above.

[0163] like Fig.13 As further shown, in some aspects, process 1300 may include receiving a cell coverage indication from a network entity, wherein the cell coverage indication includes information about a plurality of sub-areas within a cell (block 1320). Fig.14 The communications manager 140 and / or receiving component 1402 depicted in FIG. 140 may receive a cell coverage indication from a network entity, wherein the cell coverage indication includes information about a plurality of sub-areas within a cell, as described above.

[0164] like Fig.13 As further shown, in some aspects, process 1300 may include performing, during an idle mode of the UE, measurements of frequencies associated with the TN cell based at least in part on the cell coverage indication and the UE's location within one of a plurality of sub-areas within the cell (block 1330). Fig.14 The communication manager 140 and / or measurement component 1408 depicted in FIG. 1 may perform measurements of frequencies associated with a TN cell during an idle mode of the UE based at least in part on the cell coverage indication and the UE's location within one of a plurality of sub-areas within the cell, as described above.

[0165] Process 1300 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.
