Abstract

A network node (600), computer program product, and a method by a network node to allocate at least two beams in a slot to schedule multiple user equipments, UEs, (500) are provided. Each UE is allocated (801) to a baseband port (0, 1) of a plurality of baseband ports such that there is more than one UE allocated to each baseband port. For each baseband port of the plurality of baseband ports: the baseband port is mapped (803) to a polarization of an antenna having multiple polarizations and to one beam of a plurality of beams. The polarization of a baseband port is switched (805) in a time domain to create time diversity of services towards the multiple UEs, wherein a UE is subject to a first polarization for a subset of time occasions and to a second polarization for other time occasions.
