Patent ID: 11901986

Abstract:
A method for providing signals for beam-formed transmission comprises retrieving, from a memory, of first vector-associated data defined by an obtained first beam index, assigned to a first signal, scheduled to be transmitted by beamforming in a first direction. The memory has vector-associated data characterizing at least two sets of beamforming vectors for each polarization and for each one of a plurality of beam directions. The beamforming vectors for each polarization and plurality of directions present different tapering and/or non-tapering. The first vector-associated data characterizes a first selected set of beamforming vectors that are designed to give a beam in the first direction. The first beam index comprises information for defining vector-associated data characterizing a particular one of the at least two sets for the first direction. A beamforming of the first signal is initiated by use of the first vector-associated data.
