Abstract:
1. A method for LTE or WiMAX scheduling comprising the steps of: collecting, by a basestation BS, channel feedback from multiple mobiles with downlink traffic, the channel feedback enabling the BS for determining an achievable rate or block error probability if transmitting to a mobile with a given modulation and coding scheme MCS and multiple-input multiple-output MIMO mode; and determining, by the BS, which of the mobiles is scheduled on each resource block RB and what the MCS and MIMO mode is selected for each scheduled the mobile, and allocating bits on the set of the RBs assigned to each scheduled mobile, wherein the determining comprises determining a weighted rate v(u,n,m) and gain g(u,m) and when a MIMO rank is one and there is one codeword and one MCS, for a backlogged traffic model, the weighted data rate is based in part on v(u,n,m)=w v(u,n,m) representing the weighted data rate for user u on resource block RB n with transmission mode m with queue size limit, and g(u,m) representing the total gain of user u with transmission mode m on all resource blocks RBs when scheduling user u with transmission mode m.
