Abstract
Systems and methods for sampling clock alignment and time offset signaling are disclosed herein. A transmitter broadcasting symbol-aligned frames at multiple baseband sampling rates can benefit from generating the frames to have durations that can be represented by an integer number of samples at two or more of the baseband sampling rates. In some embodiments, a transmitter adds samples to a frame to ensure that its duration meets such a criteria. Furthermore, the problem of signaling network time in symbol-aligned frames is simplified by sampling clock alignment. Approaches for signaling time offset of a transmission to the nearest millisecond boundary are also presented.
