Abstract
One or more embodiments of devices, systems and method are provided for receiving and transmitting signals over a time division duplex (TDD) communication path. Signals are received over the TDD communication path via a first portion of a first frequency band. A method may include sending a time division duplex (TDD) signal via an uplink portion of a TDD communication path and receiving a TDD signal via a downlink portion of the TDD communication path. The uplink portion arises over an uplink period and the downlink portion arises over a downlink period. The TDD communication path is disposed between and mutually exclusive of a broadcast communication path and an FDD communication path. The uplink portion of the TDD communication path is separated from the broadcast communication path by an uplink guard band. The downlink portion of the TDD communication path may be contiguous with the broadcast communication path.
