Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 378,741, filed on October 7, 2022, entitled “NON-TERRESTRIAL NETWORK COMMUNICATIONS” 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 user equipment processing time for non-terrestrial network communications. 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 network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[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: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, 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 to better integrate with other open standards; and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0022] 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 construed 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.

[0023] 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.

[0024] 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 RATs beyond 5G (e.g., 6G).

[0025] Figure 11 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 network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). For another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0026] In some examples, the network node 110 is or includes a network node (such as an RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 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, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0027] In some examples, the network node 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 ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 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 a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a 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 a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0028] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions, but not another base station function. In this way, a single device may include more than one base station.

[0029] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 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 in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0030] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0031] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0032] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet 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, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.

[0033] 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, which may communicate with a network node, 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, a processor component and a 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.

[0034] 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.

[0035] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0036] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., according to 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. A similar naming problem sometimes occurs 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).

[0037] 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, so 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.

[0038] 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.

[0039] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may: obtain a first value associated with sending an uplink communication corresponding to a downlink communication received in a non-terrestrial network (NTN); compare the first value with a second value; and selectively send the uplink communication or selectively process the downlink communication based at least in part on the result of comparing the first value with the second value. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0040] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The content described is different.

[0041] Figure 22 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0042] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120, and may provide data symbols for UE 120. 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., precoding) 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 upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0043] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 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.

[0044] 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 network node 110 via the communication unit 294.

[0045] 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.

[0046] 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 sent to the network node 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 operations described herein (eg, with reference to Figures 5 to 7 ) or any aspects of any of the methods described herein.

[0047] At the network node 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 (shown as DEMOD) of the modem 232), 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 network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 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 5 to 7 ) or any aspects of any of the methods described herein.

[0048] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in the may perform one or more techniques associated with UE processing time for NTN communications, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of may perform or direct e.g. Figure 6 600 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion and / or interpretation), may cause the one or more processors, UE 120 and / or network node 110 to perform or direct, for example, Figure 6 The process 600 of 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.

[0049] In some aspects, a UE, such as UE 120, includes a first value associated with sending an uplink communication corresponding to a downlink communication received in an NTN; a first value for comparing the first value with a second value; and / or a first value for selectively sending an uplink communication or selectively processing a downlink communication based at least in part on the result of comparing the first value with the second value. The components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0050] 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.

[0051] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2The content described is different.

[0052] The deployment of a communication system such as a 5G NR system can be arranged in a variety of ways with various components or components. 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, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs or a combination thereof).

[0053] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is 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 examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. 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, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0054] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0055] Figure 33 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control 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 respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0056] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being 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 one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0057] In some aspects, CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by CU 310. CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, CU 310 may be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP 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.

[0058] Each 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, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partitioning (such as that defined by 3GPP). In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0059] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions based on functional split (e.g., functional split defined by 3GPP) (such as lower layer functional split), such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific 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 each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0060] The SMO framework 305 may be configured to support RAN deployment and provisioning 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) platform 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, non-RT RIC 315, and near-RTRIC 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 implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0061] 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.

[0062] 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 regulate 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 the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0063] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The content described is different.

[0064] Figure 4 is a diagram illustrating an example 400 of a regenerative satellite deployment and an example 410 of a transparent satellite deployment in a non-terrestrial network.

[0065] Example 400 illustrates a regenerative satellite deployment. In example 400, UE 120 is served by satellite 420 via service link 430. For example, satellite 420 may include network node 110 (e.g., network node 110a) or a gNB. In some aspects, satellite 420 may be referred to as a non-terrestrial base station, a regenerative repeater, or an onboard processing repeater. In some aspects, satellite 420 may demodulate uplink radio frequency signals and may modulate baseband signals derived from the uplink radio signals to produce downlink radio frequency transmissions. Satellite 420 may transmit downlink radio frequency signals on service link 430. Satellite 420 may provide a cell covering UE 120.

[0066] Example 410 shows a transparent satellite deployment, which may also be referred to as a bent-pipe satellite deployment. In example 410, UE 120 is served by satellite 440 via service link 430. Satellite 440 may be a transparent satellite. Satellite 440 may relay signals received from gateway 450 via feeder link 460. For example, a satellite may receive an uplink radio frequency transmission, and may transmit a downlink radio frequency transmission without demodulating the uplink radio frequency transmission. In some aspects, the satellite may convert the frequency of the uplink radio frequency transmission received on service link 430 to the frequency of the uplink radio frequency transmission on feeder link 460, and may amplify and / or filter the uplink radio frequency transmission. In some aspects, the UE 120 shown in examples 400 and 410 may be associated with a global navigation satellite system (GNSS) capability or a global positioning system (GPS) capability, but not all UEs have such capabilities. Satellite 440 may provide a cell covering UE 120.

[0067] The service link 430 may include a link between the satellite 440 and the UE 120 and may include one or more of an uplink or a downlink. The feeder link 460 may include a link between the satellite 440 and the gateway 450 and may include one or more of an uplink (e.g., from the UE 120 to the gateway 450) or a downlink (e.g., from the gateway 450 to the UE 120). The uplink of the service link 430 may be indicated by the reference numeral 430-U ( Figure 4 ), and the downlink of the service link 430 may be indicated by reference numeral 430-D ( Figure 4 Similarly, the uplink of the feed link 460 may be indicated by reference numeral 460-U ( Figure 4 ), and the downlink of the feeder link 460 may be indicated by reference numeral 460-D ( Figure 4 ) indication.

[0068] Due to the movement of satellites 420 and 440 and the potential movement of UE 120, feeder link 460 and service link 430 may each experience Doppler effects. These Doppler effects may be significantly greater than the Doppler effects in the ground network. The Doppler effect on feeder link 460 can be compensated to a certain extent, but may still be associated with a certain amount of uncompensated frequency error. In addition, gateway 450 may be associated with residual frequency error, and / or satellite 420 / 440 may be associated with onboard frequency error. These frequency error sources may cause the downlink frequency received at UE 120 to deviate from the target downlink frequency.

[0069] In some cases, UE 120 may require a certain amount of processing time to process downlink communications (e.g., downlink signals) in the NTN. The processing time may correspond to a time between a first time that UE 120 receives a downlink communication in the NTN and a second time that UE 120 sends an uplink communication corresponding to the downlink communication in the NTN. UE 120 may be a low complexity UE, such as a narrowband (NB)-IoT UE. In some cases, the configured processing time may be based at least in part on conditions associated with a terrestrial network (TN). However, communications occurring in the NTN may have one or more components that are not included in communications occurring in the TN. For example, communications in the NTN may have one or more timing relationship components for communications having uplink interactions and downlink interactions, such as narrowband physical downlink shared channel (NPDSCH) communications that trigger hybrid automatic repeat request acknowledgement (HARQ-ACK). Some example timing relationship components may include an NTN scheduling offset (K offset ), a UE-specific timing advance value (UE-specific TA) based at least in part on a round trip time between UE 120 and a network node (such as satellite 420 or satellite 440), and a common timing advance value (common TA) based at least in part on a feeder link round trip time (such as feeder link 460). The values ​​of these timing relationship components may affect UE 120 (e.g., a NB-IoT UE) in maintaining sufficient processing time.

[0070] In one example, the downlink communication in the NTN may be a NPDSCH requesting a HARQ-ACK. The UE 120 may receive the NPDSCH in a slot ending in subframe n (which may be a NB-IoT subframe). In this case, the UE 120 may start sending the HARQ-ACK after the following have ended:

[0071] n+k′0+K offset -1 for DL ​​subframes for frequency division duplex (FDD), where k′0 is the scheduling offset associated with NPDSCH.

[0072] In FDD for TN communication, K offset Can be equal to zero (K offset =0). In this case, the processing time that UE 120 has to generate HARQ-ACK may be:

[0073] k′0-1-[T TA,terrestrial ],in

[0074] T TA,terrestrial is the timing advance value used for terrestrial communications, and

[0075] [TTA,terrestrial ] is the timing advance value used for terrestrial communications normalized to a time unit, such as a time slot or a subframe.

[0076] For legacy TN communications (e.g. non-FDD communications), the timing advance value (T TA,terrestrial ) can be very small. Therefore, the minimum processing time required for UE 120 to perform TN communication is:

[0077] in

[0078] is the minimum processing time required to handle TN communications, and

[0079] is the minimum scheduling offset associated with NPDSCH.

[0080] The timing advance value used for NTN communication may be greater than the timing advance value used for TN communication. In some cases, the timing advance value used for communication in the NTN network may be:

[0081] in

[0082] T TA,NTN is the NTN timing advance value,

[0083] N TA is the timing advance value for UE 120,

[0084] N TA,offset is a fixed timing advance offset that may be used by UE 120 to calculate the timing advance to be applied for uplink transmissions,

[0085] is a component of the NTN timing advance value based at least in part on the feeder link round trip time,

[0086] is a component of the NTN timing advance value based at least in part on the network node to UE (eg, satellite to UE) round trip time, and

[0087] T s It is a constant equal to 1 / (15000×2048) seconds.

[0088] In some cases, due to the (non-zero) K in the NTN ofxfset , the processing time for UE 120 to generate HARQ-ACK in NTN may be:

[0089] k′0-1+K offset -[T TA,NTN ],in

[0090] [T TA,NTN ] is the NTN timing advance value normalized to a time unit (such as a time unit of a time slot or a subframe).

[0091] In some cases, for a given scheduling offset, the processing time available to UE 120 to generate and / or send uplink communications may be less than the terrestrial processing time. For example, if Then for a given value of k′0, the processing time available for UE 120 to generate HARQ-ACK and / or send HARQ-ACK in response to NPDSCH communication may be less than the terrestrial processing time. For example, this may occur when UE 120 is located at a cell edge and / or in a cell, where K offset In other examples, it is not conservatively configured. In this case, UE 120 may not be able to meet shorter processing time requirements, such as ground network processing time requirements. This may cause communication interruption between UE 120 and network node 110 (e.g., satellite 420 or satellite 440) and may cause waste of energy and processing resources of UE 120.

[0092] Techniques and apparatus for UE processing time for NTN communications are described herein. In some aspects, a UE may receive downlink communications in an NTN. The downlink communications may be, for example, NPDSCH communications. The UE may obtain a first value, such as a first processing time associated with sending an uplink communication corresponding to a downlink communication in the NTN. For example, the UE may calculate a first processing time associated with sending a HARQ-ACK corresponding to a NPDSCH communication in the NTN. The UE may compare the first value with a second value. The second value may be based at least in part on a scheduling offset or a time value. The UE may selectively send an uplink communication based at least in part on comparing the first value with the second value. For example, the UE may send a HARQ-ACK based at least in part on the first value being greater than or equal to the second value, or may suppress sending the HARQ-ACK based at least in part on the first value being less than the second value. This may improve the reliability of communications between the UE and a network node (e.g., a satellite) and may result in lower energy consumption for the UE.

[0093] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The content described is different.

[0094] Figure 55 is a diagram illustrating an example 500 of UE processing time for NTN communication according to the present disclosure. UE 120 may communicate with network node 110 using NTN communication. Network node 110 may be a satellite (such as satellite 420 or satellite 440) or may be another NTN node capable of NTN communication.

[0095] As shown by reference numeral 505, the network node 110 may send and the UE 120 may receive a downlink communication. The downlink communication may be an NTN downlink communication, such as a downlink communication received in an NTN network. In some aspects, the downlink communication may be an NPDSCH requesting a HARQ-ACK.

[0096] As shown by reference numeral 510, UE 120 may obtain a first value. The first value may be a first processing time associated with UE 120 processing downlink communications and / or may be based at least in part on one or more of the values ​​described herein, such as NTN scheduling offset (K offset ) or a scheduling offset (k′0) associated with downlink communication, etc. In some aspects, UE 120 may obtain the first value based at least in part on UE configuration information and / or information received from network node 110. Additionally or alternatively, UE 120 may calculate the first value based at least in part on UE configuration information or information received from network node 110.

[0097] As shown by reference numeral 515, UE 120 may compare the first value to a second value. The second value may be a second processing time and / or may be based at least in part on one or more of the values ​​described herein, such as an NTN timing advance value (T TA,NTN ); one or more components of the NTN timing advance value, such as a component of the NTN timing advance value based at least in part on the feeder link round trip time or a component of the NTN timing advance value based at least in part on the satellite-to-UE round trip time Minimum processing time for handling TN communication Or the minimum processing time value (such as minimum physical time); and so on.

[0098] As indicated by reference numeral 520, UE 120 may selectively send uplink communications or selectively process downlink communications based at least in part on a result of comparing the first value with the second value (eg, based at least in part on a result of comparing the first processing time with the second processing time).

[0099] In a first example, the first value may be the NTN scheduling offset (K offset) or may be based at least in part on the NTN scheduling offset (K offset The second value may be based at least in part on a component of the NTN timing advance value associated with the feeder link round trip time The component of the NTN timing advance value associated with the satellite-to-UE round-trip time and constant (T s ). For example, the second value may be based at least in part on In this example, when the first value is less than the second value, UE 120 may not send uplink communications. Alternatively, when the first value is greater than or equal to the second value, UE 120 may send uplink communications. , UE 120 may refrain from sending uplink communications (such as HARQ-ACK) corresponding to downlink communications (such as NPDSCH). Alternatively, when UE 120 may send uplink communications.

[0100] In a second example, the first value may be, or may be based at least in part on, a processing time required for UE 120 to generate and / or send uplink communications. In this example, the first value may be a first processing time (K) based at least in part on the NTN scheduling offset. offset ), the scheduling offset (k′0) and the NTN timing advance value (T TA,NTN For example, UE 120 can determine based at least in part on (k′0-1+K offset -[T TA,NTN ]) to calculate the first processing time. The second value may be the minimum processing time for processing TN communication In some aspects, for handling TN communications The minimum processing time can be equal to in is the maximum processing time required to process TN communications. In this example, when the first value is greater than or equal to the second value, UE 120 may send uplink communications. Alternatively, when the first value is less than the second value, UE 120 may not send uplink communications. For example, when , UE 120 may send uplink communications. , UE 120 may refrain from sending uplink communications.

[0101] In a third example, UE 120 may be configured with multiple values ​​for the NTN-specific scheduling offset (k′0). UE 120 may select a scheduling offset from the multiple scheduling offsets such that the processing time available to UE 120 to generate and / or send uplink communications is greater than or equal to the processing time required for UE 120 to generate and / or send uplink communications. In one example, K offset can be equal to 4ms, [T TA,NTN ] can be equal to 7ms, and 11 ms. UE 120 may be configured with multiple scheduling offsets (k′0) equal to 13 ms, 14 ms, 15 ms, and 16 ms. UE 120 may select a scheduling offset (k′0) such that for NTN communications, For example, UE 120 may select a value of 15 ms (or 16 ms) so that In this case, the scheduling offset (k'0) may be 15 ms (or 16 ms) for NTN communication, but may be 11 ms for TN communication. If the scheduling offset (k′0) is greater than 0, UE 120 may refrain from sending uplink communications.

[0102] In a fourth example, UE 120 may be configured with a minimum processing time (in ms), such as a minimum physical time for processing downlink communications in the NTN. In this example, the second value may be equal to the minimum processing time. If the time required for UE 120 to generate and / or send uplink communications (e.g., the first value) is greater than or equal to the minimum processing time, UE 120 may send uplink communications. Alternatively, if the time required for UE 120 to generate and / or send uplink communications is less than the minimum processing time, UE 120 may not send uplink communications.

[0103] In a fifth example, UE 120 may not send (eg, may refrain from sending) uplink communications within the minimum processing time For example, UE 120 may discard the part that occurred before the minimum processing time. One or more time slots, one or more symbols, one or more subframes, or one or more repetitions of a previously scheduled uplink communication. Additionally or alternatively, UE 120 may perform the minimum processing time The uplink communication (eg, the portion of the uplink communication or another portion of the uplink communication) is then transmitted.

[0104] In some aspects, UE 120 may selectively send uplink communications based at least in part on any combination of the first example, the second example, the third example, the fourth example, and the fifth example. And if Then UE 120 can send uplink communications. Alternatively, if or if UE 120 may then not send uplink communications.

[0105] In some aspects, the downlink communication may be a NPDSCH that triggers HARQ-ACK, the uplink communication may be a HARQ-ACK, and the scheduling offset may be a scheduling offset k′0. However, the techniques and apparatus described herein may be applicable to any type of downlink and uplink combination. For example, the downlink communication may be a narrowband physical downlink control channel (NPDCCH) communication that triggers a narrowband physical uplink shared channel (NPUSCH) communication, the uplink communication may be a NPUSCH communication, and the scheduling offset may be a scheduling offset k0. In another example, the downlink communication may be a NPDCCH communication of a narrowband physical radio access channel (NPRACH) communication that triggers a physical downlink control channel (PDCCH) command, the uplink communication may be a NPRACH communication of a PDCCH command, and the scheduling offset may be a scheduling offset k2.

[0106] In some aspects, the UE 120 may initiate (e.g., declare) a radio link failure (RLF), may transition to an idle state of the UE, or may wait to be released from a connection with the network node 110. For example, the UE 120 may initiate the RLF based at least in part (e.g., according to the first example) that the configured NTN scheduling offset is less than the NTN timing advance value, may transition to the idle state, or may wait to be released from a connection with the network node 110. In another example, the UE 120 may initiate the RLF based at least in part (e.g., according to the second example) that the first processing time is less than the second processing time, may transition to the idle state, or may wait to be released from a connection with the network node 110. In another example, the UE 120 may initiate the RLF based at least in part (e.g., according to the fourth example) that the first value is less than the minimum physical time, may transition to the idle state, or may wait to be released from a connection with the network node 110. In some aspects, the UE 120 may wait for an amount of time (e.g., in ms, time slots, subframes, etc.) during which the processing time requirement is not met before initiating RLF. In some aspects, there may be a recovery period before the UE 120 initiates RLF. During the recovery period, the UE 120 may request a different K from the network. offsetOr you can try to re-acquire K if it is updated by the network offset .

[0107] As described herein, for a given scheduling offset, the processing time available to UE 120 to generate and / or send uplink communications may be less than the terrestrial processing time. Then for a given value of k′0, the processing time available for UE 120 to generate HARQ-ACK and / or send HARQ-ACK in response to NPDSCH communication may be less than the terrestrial processing time. For example, this may occur when UE 120 is located at a cell edge and / or in a cell, where K offset In other examples, it is not conservatively configured. In this case, UE 120 may not be able to meet shorter processing time requirements, such as TN processing time requirements. This may cause communication interruption between UE 120 and network node 110 (e.g., satellite 420 or satellite 440) and may cause waste of energy and processing resources of UE 120. Using the techniques and devices described herein, UE 120 can obtain a first value, such as a first processing time associated with sending an uplink communication corresponding to a downlink communication in NTN. UE 120 can compare the first value with the second value. The second value can be based at least in part on a scheduling offset or a time value. UE 120 can selectively send uplink communication based at least in part on comparing the first value with the second value. For example, UE 120 can send HARQ-ACK based at least in part on the first value being greater than or equal to the second value, or can suppress sending HARQ-ACK based at least in part on the first value being less than the second value. This can improve the communication reliability between UE 120 and network node 110 and can make the energy consumption of UE 120 lower.
