Title:
ASYMMETRIC TDD IN FLEXIBLE USE SPECTRUM
Document Type and Number:
Japanese Patent JP2015130686
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To meet a need for new methods for asymmetric communication in wireless communication systems.SOLUTION: 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.
