20. A method for transmitting or receiving data of a user equipment in a wireless communication system data,
wherein the wireless communication system comprises a plurality of user equipments and a plurality of transmission/reception points, TRPs, the plurality of TRPs comprising at least a first TRP and a second TRP,
wherein the user equipment is a member of a group of user equipments, the group including
two or more user equipments for which second order channel statistics for at least one channel parameter between the first and second TRPs and the user equipment are within a certain range, or
two or more user equipments which are in a certain geographical area or coverage footprint relative to the first and second TRPs, and
wherein the method comprises:
communicating with the first and second TRPs using first resources, the first resources being orthogonal to second resources used by another user equipment of the group, and
for transmitting or receiving data of the user equipment
transmitting to or receiving from the first TRP a first superimposed signal using resources of the first TRP and comprising a data signal of the user equipment superimposed with a data signal of a further user equipment being a member of a further group of user equipments, and
transmitting to or receiving from the second TRP a second superimposed signal using resources of the second TRP and comprising a further data signal of the further user equipment superimposed with a further data signal of the user equipment.
