Abstract: Various mechanisms for paging link-budget-limited (LBL) devices are disclosed, including: (1) transmitting paging message with non-conventional paging identifier; (2) transmitting paging message(s) with increased power; (3) repeating transmission of paging message to support combining at receiver. Various mechanisms for UE device to signal LBL status are disclosed, including, transmitting status flag or special value of DRX cycle to network node as part of tracking area update and/or attach request. The network node informs a base station of the device's LBL status as part of a paging message. (The network node may, e.g., assign an S-RNTI to the LBL device from a reserved subset of S-RNTI space.) The base station invokes a paging enhancement mechanism when paging an LBL device. Alternatively, the base station may page UE devices without knowledge of LBL status, e.g., by counting paging attempts for a given UE, and boosting power after the Nth paging attempt.

Abstract: The topology of a filling material surface is first determined by sampling the surface of the filling material in order to determine the fill level. When calculating the surface topology of the filling material, the measurement signal, which has been reflected at the filling material surface and has been picked up by the antenna unit of the fill level measurement device, is evaluated, taking into account the distance between the source of the measurement signal and a center of rotation of the main emission axis of the antenna. This makes it possible to accurately determine the fill level of bulk materials, even if the source of the measurement signal and the center of rotation of the main emission axis do not coincide.

Abstract: Mobile devices such as cellular telephones are provided that communicate with wireless networks. Cellular telephone network equipment may communicate with a cellular telephone over a data connection. The cellular telephone may have an internet protocol (IP) address that allows data to be provided to the cellular telephone over the data connection. To conserve resources and release unused IP addresses, the cellular telephone network equipment may deactivate inactive data connections after a period of inactivity. A baseband processor within a mobile device may periodically send User Datagram Protocol (UDP) keep-alive packets over the data connection to ensure that the data connection remains active. The keep-alive packets may be directed to a packet sink server or may be associated with a black hole route. An applications processor in the telephone may remain in sleep mode during keep-alive packet transmission to conserve power.

Abstract: To enable multiple message originators to share an SMS shortcode, originator identifying codes can be added to outbound SMS messages that prompt recipients to respond with response messages that include the originator identifying codes. The originator identifying codes can be added by a service provider that administers the SMS shortcode. When a response message is received on the SMS shortcode number, the service provider processes the response message content to extract the originator identifying code. The code and, optionally, a recipient ID can be used as a lookup to determine the intended originator that the response message is for. The response message can then be associated by the service provider with the correct originator for subsequent processing.

Abstract: This document describes apparatuses and techniques for radar-based contextual sensing. In some aspects, a radar sensor of a device is activated to obtain radar data for a space of interest. Three-dimensional (3D) radar features are extracted from the radar data and positional data is received from sensors. Based on the positional data, spatial relation of the 3D radar features is determined to generate a set of 3D landmarks for the space. This set of 3D landmarks is then compared with known 3D context models to identify a 3D context model that matches the 3D landmarks. Based on a matching 3D context model, a context for the space is retrieved and used to configure contextual settings of the device. By so doing, contextual settings of the device be dynamically configured to address changes in context or for different device environments.

Abstract: An apparatus may include a plurality of antenna elements forming an antenna array. The apparatus may further include a beamformer that determines one or more of phase and amplitude shifts to cause the plurality of antenna elements to produce a beam in the direction of a target. The apparatus may further include a null limiter comprising dither circuits. The dither circuits may dither the one or more of phase and amplitude shifts by adding noise to cause a side lobe of the beam to increase above a threshold value. The dither circuits may be enabled by a control signal, and the dithered one or more of phase and amplitude shifts may be provided to the antenna elements to produce the beam in the direction of the target with the side lobes above the threshold value.

Abstract: Antennas used aboard aircraft to communicate with satellites or ground stations may have complex antenna patterns, which may vary as the aircraft moves throughout a given coverage area. Techniques are disclosed for dynamically adjusting the instantaneous power fed to an antenna system to ensure that the antenna transmits at the regulatory or coordinated effective isotropic radiated power (EIRP) spectral limit. The antenna may transmit, in accordance with aircraft location and attitude, steerable beam patterns at different scan and skew angle combinations, causing variations in antenna gain and fluctuations in the transmitted EIRP. Using on-board navigational data, an antenna gain and ESD limit may be calculated for a particular scan and skew angle, which may be used to adjust power fed to the antenna such that the antenna transmits substantially at maximum allowable EIRP as the steerable beam pattern is adjusted.

A vehicle can transmit radio waves to an area the vehicle is traveling to, such as a road in front of an automobile. The automobile can receive and process returned radio waves to determine if the road has a non-uniformity, such as a significant pothole or speed bump. If the road has the non-uniformity, then a driver of the automobile can be alerted so the driver can decide if evasive action should be taken and take such action if appropriate.
