Title:
Asymmetrical TDD in the spectrum which can be used flexibly
Document Type and Number:
Japanese Patent JP6334766
Kind Code:
B2
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.
