Claim One:
1. A method comprising: (a) initiating a multiple input and multiple output (MIMO) training procedure in a wireless network; (b) transmitting training frames using all TX sectors during TX sector sweeping for obtaining a set of selected TX sectors for each TX antenna, wherein each of the TX sectors corresponds to a specific TX antenna beam; (c) obtaining a set of selected RX sectors for each RX antenna, wherein each of the RX sectors corresponds to a specific RX antenna beam; (d) performing MIMO beam combination training based on pairings of the selected TX and RX sectors, wherein each of the MIMO beam combinations includes one TX sector from the set of selected TX sectors and one RX sector from the set of selected RX sectors; and (e) obtaining multiple best MIMO beam combinations for multiple MIMO spatial streams based on the MIMO beam combination training.
