Abstract
Various aspects of the present disclosure provide for methods, apparatus, and computer software for multiple access to a channel carrying a common uplink burst transmitted by users that utilize two different modes. Specifically, a coupled mode provides for range extension for users at a cell edge, while a decoupled mode provides for user data transmissions within the common uplink burst. Multiple access between these different modes may be provided in a non-orthogonal scheme by moderating the amount of interference between the respective modes. Further, multiple access between these different modes may be provided in an orthogonal scheme by utilizing interleaved frequency division multiple access (IFDMA).
