Method and systems are provided for receiving and transmitting signals over a time division duplex communication path (the “Path”). Operations may include sending a first signal via an uplink portion of the Path, and receiving a second signal via a downlink portion of the Path. The Path operates over a first band having a first frequency range and during a communication time including an uplink period (TU) and a downlink period (TD). The uplink portion is sent during the uplink period, uses a first portion of the first frequency range and is disposed between a first uplink guard band portion and a second uplink guard band portion. The guard bands are allocated from a second portion and a third portion of the first band. The first band is disposed between a second band, providing a second communication path, and a third band providing an FDD communication path.

Asymmetric TDD in flexible use spectrum

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.

An active optical cable (AOC) signals to a source that it needs power above a standard voltage, e.g., above five volts, by sending a signal such as a voltage step from one non-zero voltage to a second non-zero voltage or other voltage pattern on a hot plug detect (HPD) pin of a display data channel (DDC). While a legacy source device may not be able to detect this and consequently will operate as usual, a source device programmed according to present principles detects the request for more power represented by the voltage pattern established by the AOC, and in response increases the power (voltage and/or current) on DDC 5V line to the requested level, e.g., 10V at 500 mA.
