1. A method, performed by a transmitter node, for enabling reception beam selection at one or more receiver nodes, the method comprising:
obtaining a polarization profile, wherein the polarization profile defines a respective polarization for a sequence of probing occasions,
providing, to the receiver node, control information indicative of the polarization profile,
transmitting, in one single transmission beam, a pilot signal having a first polarization, in each of N probing occasions, wherein N is defined by the polarization profile;
transmitting, subsequent to transmission of the pilot signals having the first polarization, and in one single transmission beam, a pilot signal having a second polarization, in each of M probing occasions, wherein M is defined by the polarization profile; and
wherein M is smaller than N and M is non-zero.
