Method for selecting switched orthogonal beams for downlink diversity transmission
First Claim
1. A method for selecting two beams in a switched beam antenna system for providing downlink communications in a downlink channel, the switched beam antenna system providing uplink reception and downlink transmission, the method comprising the steps of:
- selecting a pair of beams based on the uplink reception of the switched beam antenna system;
determining from the pair of beams a corresponding pair of orthogonal beams; and
providing the pair of orthogonal beams as a pair of transmit beams for the downlink transmission of the switched beam antenna system.

Abstract
A scheme for selecting two beams in a switched beam antenna system for providing downlink communications in a downlink channel, the switched beam antenna system providing uplink reception and downlink transmission is described. The scheme involves selecting a pair of beams based on the uplink reception of the switched beam antenna system, and determining from the pair of beams a corresponding pair of orthogonal beams. The scheme also involves providing the pair of orthogonal beams as a pair of transmit beams for the downlink transmission of the switched beam antenna system.
