Abstract:
1. A method of generating a signal for wireless transmission in a communication system serving a plurality of cells, the method comprising: forming a plurality of signal transmission frames, wherein each transmission frame is partitioned into a plurality of subframes, and wherein each subframe is further divided into a plurality of time-slots; configuring each subframe with a predetermined ratio of downlink time-slots and uplink time-slots, wherein the predetermined ratio of a number of downlink time-slots and a number of uplink time-slots varies between two or more subframes; inserting at least one special downlink period (SDP) in a transmission frame, during which a base station broadcasts control information including a cell identity; inserting at least one special uplink period (SUP) in a transmission frame, during which a mobile station is capable of carrying out radio functions; and forming a plurality of orthogonal frequency division multiplexing (OFDM) symbols in one or more time-slots by:
