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.
Claims20
A method, comprising:
- determining a transmission zone for each of a plurality of users, wherein the transmission zone includes an angle of direction of a directional beam from a base station to each user, and a deviation of the angle of direction of the directional beam;
- determining a precoding of transmission signals to each of the plurality of users from the base station, comprising:
- constructing the precoding for each user based on the transmission zone determined for each of other users of the plurality of users;
- and
- applying the precoding of each user to wireless communication signals communicated between the base station and the user.
A base station, comprising:
- a plurality of antennas;
- a plurality of radios connected to the plurality of antennas;
- a controller, wherein the controller operates to:
- determine a transmission zone for each of a plurality of users,
- wherein the transmission zone includes an angle of direction of a directional beam to each user from the base station formed by the plurality of antennas, and a deviation of the angle of direction of the directional beam;
- determine a precoding of transmission signals to each of the plurality of users from the base station, comprising:
- constructing the precoding for each user based on the transmission zone determined for each of the other users;
- and
- apply the precoding of each user to wireless communication signals communicated between the plurality of antennas of the base station and the user.
