(57) ABSTRACT A method and apparatus for performing spatial-division mul tiple access
within a communication system is provided herein. During operation, nodes will return null
subspace information along with their channel Subspace information. The null Subspace is
similar to the channel Subspace except that the null subspace information directs a base
station to the matrix in a predefined codebook that results in minimum power being received
at the node. The null subspace for each node is taken into consideration when …
