1. A method for a transmitter apparatus configured to transmit signals to a receiver apparatus using a transmission beam selected from a plurality of available transmission beams, wherein the receiver apparatus is configured to receive the signals using a reception beam selected from a plurality of available reception beams, and wherein a set of the available transmission beams and a set of the available reception beams are for beam selection measurements by the receiver apparatus, the method comprising:
determining, jointly, a collection of linear combinations of transmission beams of the set of the available transmission beams and a collection of linear combinations of reception beams of the set of available reception beams; and
transmitting each of the linear combinations of transmission beams of the collection of linear combinations of transmission beams for beam selection measurements by the receiver apparatus.
 
14. A method for a receiver apparatus configured to receive signals from a transmitter apparatus via a transmission beam selected from a plurality of available transmission beams and using a reception beam selected from a plurality of available reception beams, wherein a set of the available transmission beams and a set of the available reception beams are for beam selection measurements by the receiver apparatus, the method comprising:
receiving, using each linear combination of reception beams of a collection of linear combinations of reception beams, a number of measurement signals for beam selection measurements from the transmitter apparatus, wherein the number of measurement signals correspond to a collection of linear combinations of transmission beams of the set of available transmission beams; and
performing beam selection measurements on the number of measurement signals for selection of the transmission beam from the plurality of available transmission beams and for selection of the reception beam from the plurality of available reception beams.
