Abstract: Over-the-air radio broadcast signals are commonly used to deliver a variety of programming content (e.g., audio, etc.) to radio receiver systems. Supplemental data (e.g., metadata) may be provided to radio broadcast receiver systems, where such supplemental data is associated with the programming content delivered via the over-the-air radio broadcast signals. In exemplary embodiments described herein, a radio receiver system receives both (i) primary programming content via over-the-air radio broadcast transmission, and (ii) metadata related to the programming content via wireless Internet. This use of metadata provides a user with an enhanced experience regardless of the type of terrestrial broadcast signal that is received at the user's radio receiver system. Users receiving radio broadcast signals at a receiver system may view images, videos, multimedia displays, text, etc., that is related to the programming content received via the over-the-air radio broadcast signals.

Abstract: A mechanism to control transmission by a base station, which may help to control interference on an adjacent frequency. The base station is configured to operate on a first frequency and is equipped with a number of antennas enabled for transmission on the first frequency. Upon detecting of a trigger for reducing potential interference on the adjacent frequency, the base station reduces the number of its antennas that are enabled for transmission on the first carrier, which may reduce the overall energy of the base station's transmission and may thereby reduce interference on the adjacent frequency. In an example implementation, the base station could disable a proper subset of its antennas from use for transmission on the first frequency, while leaving a remainder of its antennas enabled for transmission on the first frequency.

In addition, various signals are transmitted on resources corresponding to different resource pair links, so that different power control values can be set for the various signals.
