Claim 0:
1. A network node configured to communicate with a wireless device, WD, the network node configured to:
at least one of receive and estimate respective precoder information for a plurality of WDs;
determine 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;
determine 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;
determine a composite precoder matrix based at least in part on the modified precoder matrices for each of the plurality of WDs; and
determine a transmission beam shape for use in transmission to at least one of the plurality of WDs based on the composite precoder matrix.
