摘要
The present invention relates to a method and mobile terminal for transmitting data on uplink within a mobile communication system. Further the invention relates to a network entity for allocating uplink resources to such a mobile terminal. When a user equipment is transmitting uplink (UL) data according to allocated resources, it has to indicate the transport format of the current data transmission to Node B by means of UL control signaling. To propose a scheduling scheme which reduces the overhead of uplink control signaling, a method is proposed that achieves a significant reduction of the UL control signaling overhead by considering characteristics of an orthogonal radio access scheme used for evolved UTRA uplink scheme and using differential signaling of the transport format information. Although the invention is particularly suitable for uplink transmissions in an orthogonal single-carrier radio access scheme, it is not restricted to this particular embodiment.
