Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communications device detects a trigger to communicate via non-terrestrial network (NTN) connectivity, determines whether one or more obstructions are estimated to be blocking a subset of NTN space vehicles of a set of NTN space vehicles expected to be in view of the wireless communications device at a current location of the wireless communications device, and transmits, in response to a determination that the one or more obstructions are estimated to be blocking the subset of NTN space vehicles, at least one message towards at least one NTN space vehicle of the set of NTN space vehicles other than the subset of NTN space vehicles.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communication device detects a trigger to transmit a message via satellite connectivity, determines one or more alignment opportunities associated with one or more satellites, wherein each alignment opportunity of the one or more alignment opportunities is a time period during which a main lobe of an antenna of the wireless communication device is predicted to be aligned with a line-of-sight (LOS) direction to at least one satellite of the one or more satellites, transitions to a sleep state until at least one alignment opportunity of the one or more alignment opportunities, and transmits the message to the at least one satellite of the one or more satellites during the at least one alignment opportunity of the one or more alignment opportunities.

Abstract: In some implementations, a mobile device may determine a set of target orientations of the mobile device in which an antenna lobe of the mobile device is pointed toward the satellite, the set of target orientations based on: an orientation of the antenna lobe relative to the mobile device, and a location of the satellite relative to the mobile device. The mobile device may determine a current orientation of the mobile device. The mobile device may provide, at a user interface (UI) of the mobile device, guidance for rotating the mobile device from the current orientation to an orientation within the set of target orientations.

Abstract: Techniques are disclosed for satellite-based wireless communication (SBWC) satellite visibility determination based on global navigation satellite system (GNSS) satellite visibility. The techniques can include identifying one or more visible GNSS satellites based on one or more received GNSS signals, estimating an orientation of a directional radio-frequency (RF) antenna based on respective expected positions of the one or more visible GNSS satellites, determining whether any of a plurality of SBWC satellites are visible based on the estimated orientation of the directional RF antenna, and initiating an SBWC communication procedure responsive to a determination that at least one SBWC satellite among the plurality of SBWC satellites is visible.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communication device may obtain information regarding communication between the set of communication devices and a non-terrestrial network (NTN) and communicate with the NTN. The wireless communication device may communicate with the NTN directly based on the wireless communication device being identified as one of one or more selected wireless communication devices for direct communication with the NTN. The wireless communication device may communicate with the NTN indirectly via a peer-to-peer communication network and the one or more selected wireless communication devices based on the wireless communication device being not identified as any of the one or more selected wireless communication devices for direct communication with the NTN.

Abstract: In some implementations, a mobile device may perform a plurality of signal strength measurements of a radio frequency (RF) signal transmitted by a satellite, wherein performing the plurality of signal strength measurements occurs over a period of time during which the mobile device is subject to a movement. The mobile device may determine, for each signal strength measurement of the plurality of signal strength measurements, a respective orientation of the mobile device corresponding to when the respective signal strength measurement was performed. The mobile device may determine a target orientation for the satellite-based communications based at least in part on a value of a particular signal strength measurement of the plurality of signal strength measurements and the respective orientation of the mobile device corresponding to the particular signal strength measurement. The mobile device may provide guidance for rotating the mobile device to the target orientation.

Abstract: In some implementations, a device may obtain historical orbital data indicative of orbital movement of a set of satellites over a period of time, the set of satellites comprising at least a subset of satellites of the satellite constellation. The device may, for each satellite in the set of satellites, estimate a set of orbital parameter values by fitting an orbital model to the historical data of the respective satellite, wherein at least one orbital parameter value of the set of orbital values is common across a group of satellites within the set of satellites. The device may send assistance data to at least one mobile device, the assistance data indicative of the respective set of orbital parameter values for all satellites of the set of satellites.

Abstract: Systems and methodologies are described that facilitate employing a paging indicator channel in connection with high speed channels in a wireless communications network. A paging indicator transmission can be sent on the paging channel to one or more mobile devices. The paging indicator indicates that additional information such as a full paging messages, other control plane data or other user plane data is expected to be transmitted at a specific time instant (e.g., subframe) on the associated high speed channel. A set of parameters can be transmitted on common channels that specify a set of associated subframes in a high speed channel. Mobile devices can analyze the set of parameters to determine the associated subframes and receive the subframes in accordance with a schedule.

Abstract: Methods and apparatus are provided for device configuration (e.g., feature segment loading and system selection). Certain aspects of the present disclosure generally relate to operating a user equipment (UE) in a first radio access network (RAN) with a first set of modem features that supports the first RAN, detecting a second RAN not supported by the first set of modem features, and rebooting the modem software to load a second set of modem features that supports the detected RAN. For certain aspects, the first RAN may be a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network and the second RAN may be a Wideband-Code Division Multiple Access (W-CDMA) network or Long-Term Evolution (LTE) network. This allows features to be loaded into memory (e.g., only) when they are required to support a detected RAN, rather than loading an entire image, thereby conserving DRAM and increasing efficiency.

Abstract translation: 提供了用于设备配置（例如，特征段加载和系统选择）的方法和装置。 本公开的某些方面通常涉及在具有支持第一RAN的第一组调制解调器特征的第一无线电接入网络（RAN）中操作用户设备（UE），检测不被第一组调制解调器支持的第二RAN 功能和重新启动调制解调器软件以加载支持检测到的RAN的第二组调制解调器功能。 对于某些方面，第一RAN可以是时分同步码分多址（TD-SCDMA）网络，而第二RAN可以是宽带码分多址（W-CDMA）网络或长期演进（LTE） ）网络。 这允许在需要支持检测到的RAN时将特征加载到存储器（例如，仅）中，而不是加载整个图像，从而节约DRAM并提高效率。
