Claim One:
1. A method for efficiently assigning transmission parameters in a wireless communications network, the method comprising: selecting users for an initial user group in the wireless communications network; computing initial modulation coding schemes (MCSs) for users in the initial user group in the wireless communications network, wherein computing the initial MCSs for the users in the initial user group includes performing an initial QR decomposition operation for the initial user group; adding a new user to the initial user group to obtain a new user group in the wireless communications network; computing a new MCS for the new user in the new user group, wherein computing the new MCS for the new user includes calculating the new MCS directly using information obtained from the initial QR decomposition operation and without performing a QR decomposition operation for the new user group; and communicating the new MCS to a transmitter.
