Claim 10:
11. A method implemented in a network node, the method comprising:
at least one of receiving and estimating respective precoder information for a plurality of wireless devices, WDs;
determining a respective orthogonal projection matrix for each of the plurality of WDs based at least in part on the precoder information of all other WDs of the plurality of WDs;
determining a respective modified precoder matrix for each of the plurality of WDs based at least in part on the respective orthogonal matrix and precoder information for each WD of the plurality of WDs;
determining a composite precoder matrix based at least in part on the modified precoder matrices for each of the plurality of WDs; and
determining a transmission beam shape for use in transmission to at least one of the plurality of WDs based on the composite precoder matrix.
