Patent ID: 8081689

Claim:
A method for performing frequency selective control channel scheduling in networks using an Orthogonal Frequency Division Multiplexing (OFDM) spectrum, comprising: at a base station, broadcasting on at least one predefined OFDM symbol or subcarrier which is known to all mobile terminals a signaling information common to all mobile terminals indicating a position of at least one OFDM symbol or subcarrier of at least one frequency selective shared control channel and at least one identification of at least one addressed mobile terminal; sending from the base station signaling information for said at least one addressed mobile terminal at the indicated position of said at least one OFDM symbol or subcarrier of said at least one frequency selective shared control channel; and measuring at least one mobile terminal at least one OFDM symbol or subcarrier of said at least one frequency selective shared control channel for channel quality estimation; wherein the positions of said at least one OFDM symbol or subcarrier of said at least one frequency selective shared control channel are defined in such a way that said at least one mobile terminal measures OFDM symbols or subcarriers at equidistant frequency positions for channel quality estimation; wherein unused equidistant OFDM symbols or subcarriers are used for data transmission in order to guarantee a quasi-permanently coded signal for channel quality estimation; and wherein a predefined pattern is sent in OFDM symbols or subcarriers at equidistant frequency positions that are not filled with signaling information common to all mobile terminals, frequency selective shared control channel signaling information or data.
