Publication number: 20240421879Abstract: A network node, 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, are provided. Each UE is allocated to a baseband port 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 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 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.Type: ApplicationFiled: October 19, 2021Publication date: December 19, 2024Inventors: Zhiming YIN, Magnus HURD, Jonas KARLSSON, Jing RAO, Svante BERGMAN, Fredrik OVESJÖ
