Method for operating a radio communication system as well as sending station and receiving station

摘要

According to a method for operating a radio communication system which uses at least a first frequency band (FR; FR1) subdivided into C radio resource units (C1, C2, ..., C8; U1, U2, ..., U8) which are allocable for radio transmissions between radio stations and terminals, whereas each radio resource unit (C1, C2, ..., C8; U1, U2, ..., U8) consists of at least two adjacent sub carriers, for allocation of at least a first resource unit (C1, C2, ..., C8; U1, U2, ..., U8) for a data transmission between a terminal (T1, T2, T3, T4) and a radio station (BS), the radio station (BS) receives from the terminal (T1, T2, T3, T4) a first short training symbol (STS) which has spectrally the same bandwidth as the first frequency band (FR; FR1) and consists of at least Q frequency carriers whereas Q is greater or equal to C but smaller than the total number of sub carriers, the radio station (BS) estimates the radio channel for at least the first radio resource unit (C1, C2, ..., C8; U1, U2, ..., U8) using the received first short training symbol (STS), and an allocation of the first radio resource unit (C1, C2, ..., C8; U1, U2, ..., U8) to the terminal (T1, T2, T3, T4) is broadcasted by the radio station (BS).
