Abstract
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.
