Asymmetric TDD in flexible use spectrum
First Claim
1. A method, comprising:
- sending a first signal over an asymmetric time division duplex (TDD) communication path via a first portion of a first frequency band,the first frequency band being adjacent to a second frequency band and a third frequency band,the first frequency band being different from the second frequency band and the third frequency band,the second frequency band including a synchronous TDD communication path, the third frequency band including a frequency division duplex (FDD) communication path; and
receiving a second signal over the asymmetric TDD communication path via a second portion of the first frequency band different from the first portion of the first frequency band;
wherein the first portion of the first frequency band and the second portion of the first frequency band have the same time duration.

Abstract
A method according to an embodiment of the invention includes 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. The first frequency band is adjacent to a second frequency band and to a third frequency band. The first frequency band is different from the second frequency band and from the third frequency band. A first frequency division duplex (FDD) communication path can be operable in the second frequency band. A second FDD communication path can be operable in the third frequency band. Signals are transmitted over the TDD communication path via a second portion of the first frequency band that is different from the first portion of the first frequency band.
