Abstract: A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

Abstract: A computer implemented method and system for determining a communication mode for recording a media message on a communication device is provided. An adaptive recording application detects activation of an interface element, for example, a push or a touch of a button on the communication device and determines duration of the activation of the interface element. The adaptive recording application, in response to the detection of the activation of the interface element, selects a communication mode, for example, a push to talk communication mode, a tap to start communication mode, etc., based on a comparison of the duration of the activation of the interface element with one or more configurable timing parameters and/or a determination of a presence or an absence of a media signal during and/or after the activation of the interface element. The adaptive recording application initiates recording of the media message in the selected communication mode.

Abstract: Systems and techniques for locating a radio transmission source by scene reconstruction are described herein. A multipath radio signal—comprised of two or more multipath components—may be received at an antenna array. A collection of angle-of-arrival (AoA) values may be created from the multipath components. Thus, each AoA in the collection corresponds to one of the multipath components. An optical image of the environment may be obtained and possible reflective surfaces for the multipath components identified in the optical image. A set of paths may be created in a model of the environment by backtracking from the antenna array along the AoAs in the collection of AoA values. Here, the backtracking simulates reflections of the ray off of the surfaces identified in the optical image. A transmitter of the multipath radio signal may then be located via the set of paths.
