Spatial null creation using massive mimo (m-mimo)
In a base station having a massive multiple input multiple output (m-mimo) antenna array, the availability of the m-mimo antenna array is exploited to manage the interference caused by the base station to neighboring cells. In one embodiment, the large number of antenna elements of the m-mimo antenna array are used to create precise transmit and/or receive spatial nulls at specific user equipments (ues) being served by a neighboring cell and/or in select areas of the neighboring cell.
Antenna device and electronic apparatus
A square bracket-shaped radiation element is in a non-ground region of a board. A first reactance element that equivalently enters a short-circuited state in a second frequency band is connected between a second end of the radiation element and a ground conductor.
