Abstract: The disclosure relates to methods and devices for improving TX beam forming. A method according to a first approach is for determining an RX beam pattern for a user equipment, UE. A method according to a second approach is for polarization control in TX beam forming of a user equipment, UE. A method according to a third approach is for user equipment, UE, TX beam forming based on UE beam correspondence. A method according to a fourth approach is for re-acquiring a beam pair between a user equipment, UE, and a base station based on grouping information.
