Abstract:
Apparatuses, methods, and systems zone precoding are disclosed. One method includes determining a transmission zone for each of the plurality of users, wherein the transmission zone includes an angle of direction of a directional beam to each user, and a deviation of the angle of direction. Determining a precoding of transmission signals to each of the plurality of users from the base station based on the transmission zone associated with the user, and constructing the precoding for each user by adjusting the initial precoding for each user based on the transmission zone determined for each of the other users.
