SEQUENCE HOPPING IN A COMMUNICATION SYSTEM

摘要

A method and apparatus for communication of signals in a slotted communication system is disclosed. The slots are arranged into subframes of frames such that each subframe comprises at least two slots. A reference signal can be included in at least one slot of a subframe. A sequence hopping scheme is changed between at least two subframes such that a first hopping pattern is used for slots in the earlier subframe and a second hopping pattern is used for slots in the latter subframe of said at least two subframes. Orthogonal cover codes are used between the slots in said subframes.
