Abstract: Systems and methods for enabling a wireless backhaul network between access points (APs) in a wireless network are provided. In an embodiment, the wireless backhaul network is enabled using a Massive Multiple Input Multiple Output (MIMO) radio access technology (RAT). In another embodiment, the wireless backhaul network is established using the same RAT as used by the APs to serve user devices, and can utilize the same time and frequency resources used for user communication.

Abstract: A wireless communication device is disclosed that is capable of utilizing multiple radio access technologies (RATs) in various coordinated ways so as to optimize, and enhance the versatility, of the device's communication capabilities. One or more RATs may be selected for use, either alone or in cooperation with each other, based on various conditions, such as channel conditions, traffic, data type, and priority. When conditions change, the originally-selected communication scheme may no longer be preferred. Consequently, the device can initiate a handover to another communication scheme. Transmitters corresponding to RATs that are not currently selected are controlled to enter a low-power state in order to conserve power. However, in some circumstances, the device may utilize both RATs simultaneously. For example, redundant communications can be made over both RATs for error-reduction or other purposes, and partial communications can be made over multiple RATs for increased speed and bandwidth, among other reasons.

Abstract: Various methods and systems are provided for adaptable video architectures. In one embodiment, a method for adapting video processing of a video device includes processing a video stream along a first pipeline pathway defined by a plurality of interconnected pipeline elements. In response to detecting a change in a system condition of the video device, the pipeline pathway is transitioned to a second pipeline pathway by reconfiguring at least one of the pipeline element interconnections. In another embodiment, a method includes obtaining a video stream. A first subset bitstream having a first resolution is processed in a video pipeline of a video device and video information is extracted from the video pipeline during the processing. At least a portion of the extracted video information is then to a video pipeline of the video device for processing a second subset bitstream having a second resolution higher than the first resolution.
