Claim of US Patent No. 10,200,855

1. A method for adaptive multiple-input multiple-output (MIMO) transmission modes (TMs) in wireless networks, the method comprising:receiving an attachment request from a User Equipment (UE);
retrieving a Subscriber Profile ID (SPID) for the UE and qualifying the UE for an enhanced MIMO TM based on the SPID;
if the UE qualifies, then determining if the UE is capable of the enhanced MIMO TM;
if the UE is capable of the enhanced MIMO TM, then assigning the UE to the enhanced MIMO TM;
receiving a Rank Indicator (RI) from the UE in enhanced MIMO TM, and if the RI is less than a RI threshold, then assigning the UE to a lower MIMO TM, wherein the lower MIMO TM comprises at least one of MIMO TM3 and MIMO TM4.
