A method for allocating a pilot sequence comprising cancellation carriers for sidelobe reduction

摘要

The invention concerns a method for allocating a pilot sequence, a reference sequence, or a training sequence (SP1, SP2) on frequency resources which are predefined for usage of the pilot sequence, the reference sequence, or the training sequence (SP1, SP2), wherein the pilot sequence, the reference sequence, or the training sequence (SP1, SP2) is composed of at least two parts (SP1, SP2), a first part (SP1) of said at least two parts comprises at least one of a group of pilot symbols, reference symbols, and training symbols like a CAZAC sequence and a second part (SP2) of said at least two parts located at the edges of the allocated spectrum (Guard Band) comprises cancellation symbols or cancellation carriers located at the edge of said frequency resources for cancellation of sidelobes of the pilot sequence, the reference sequence, or the training sequence (SP1, SP2), and a network device therefor.
