Abstract
The present disclosure relates to a method for transmitting and receiving a beamformed data transmission transmitted from a radio base station to a user equipment over an unlicensed band. The data transmission is transmitted by the radio base station within one or more resource blocks of a subframe, each resource block being composed of a plurality of resource elements. The beamformed data transmission is generated by the radio base station by 1) applying a first precoding for generating a beam directionality towards the user equipment to a subset of all the resource elements used for transmitting the data transmission in the subframe, and 2) applying a second precoding, different from the first precoding, to the remaining resource elements used for transmitting the data transmission in the subframe so as to achieve a radiation pattern different from the beam directionality towards the user equipment.
