In case of FDD operation, acknowledgement indicators related to data transmission in a subframe n are transmitted in the opposite direction during subframe n+4, such that a one-to-one synchronous mapping exists between the instant at which the transport is transmitted and its corresponding acknowle...
which are labeled TDD Frame0, TDD Frame1, TDD Frame2, and TDD Frame9, respectively. In the exemplary embodiment, each TDD frame is 2 milliseconds in duration. A TDD transmission frame is based on a fixed period of time during which access to the channel is controlled by the transceiver ...
