摘要： When building sets of mobile stations in a radio communication network, reference signals are transmitted from a base station to at least two mobile stations to determine channel properties of a downlink channel between the base station and the at least two mobile stations. First and second feedback information are determined at the at least two mobile stations respectively, each feedback information comprising a first component indicating a channel quality. The first and the second feedback information are transmitted from the first and second mobile stations to the base station. A mobile station set is built according to the first and the second feedback information at the base station, wherein the channel quality is a parameter of a downlink beam with a largest received carrier power of at least three downlink beams of said downlink channel.

摘要： A method for allocation of parameters for radio transmission in a wireless communication network using channel feedback compression is provided. At least one channel impulse response in the time domain for at least one connection (CH13-CH24) between an antenna (A1, A2) of a transmitter (BS) and an antenna of a receiver (MS) is determined. Only the at least one complex coefficient related to one or more time intervals of the at least one channel impulse response with a power higher than a predefined threshold is fed back. Parameters for radio transmission are allocated to the at least one connection (CH13-CH24) based on the at least one channel impulse response which is fed back. Network elements and a wireless communication network associated with the method are also provided.
