METHOD AND APPARATUS TO SUPPORT SINGLE USER (SU) AND MULTIUSER (MU) BEAMFORMING WITH ANTENNA ARRAY GROUPS |
摘要 |
A method and apparatus are used to support single user (SU) and multiuser (MU) beamforming with antenna array groups. The method and apparatus are used to precode a plurality of data streams, beamform each of the data streams, and provide each of the beamformed data streams to one of a plurality of antenna array groups. An alternate method and apparatus are used to select a beamforming vector from a codebook, transmit a common reference signal (RS) based on the selection, receive an antenna configuration responsive to the common RS, estimate channels based on the antenna configuration, determine beamforming vectors for a plurality of antenna array groups, and transmit the beamforming vectors. |
