Asymmetric TDD in flexible use spectrum
First Claim
1. A method, comprising:
- sending a first signal, at a first time arising during a first time interval, over an asymmetric time division duplex (TDD) communication path, via a first portion of a first frequency band;
wherein the first frequency band is adjacent to and different from each of a second frequency band and a third frequency band;
wherein the second frequency band comprises a synchronous TDD communication path having an uplink TDD portion operating at the first time arising during the first time interval;
wherein the first time and first time interval are substantially the same for each of the first portion and the uplink TDD portion;
wherein the third frequency band includes a frequency division duplex (FDD) communication path; and
receiving a second signal during a second time interval, over the asymmetric TDD communication path, via a second portion of the first frequency band;
wherein the second portion is different from the first portion.

Abstract
A method according to an embodiment of the invention includes receiving and transmitting signals over an asymmetric time division duplex (TDD) communication path. Signals are sent over the asymmetric 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 synchronous time division duplex (TDD) communication path can be operable in the second frequency band. A frequency division duplex (FDD) communication path can be operable in the third frequency band. Signals are received over the asymmetric TDD communication path via a second portion of the first frequency band that is different from the first portion of the first frequency band.
