TIME-DIVISION DUPLEXING

摘要

A technique, comprising: controlling a radio transceiver to make and receive transmissions according to a radio frame structure comprising consecutive time frames of a predefined duration, wherein each time frame comprises a plurality of consecutive sub-frames of a predefined duration, and each sub-frame comprises a plurality of sets of time resources, and wherein said plurality of sets of time resources of a sub-frame includes: a first set useable for transmissions in a first direction; a second set useable for transmissions in a second, opposite direction; and a third set that is switchable between transmissions in said first direction and transmissions in said second direction, independently of said first and second sets of time resources in the same sub-frame and independently of other sub-frames in the same radio frame.
