System and method for hybrid schemes of MIMO mode decision

A base station for a hybrid scheme of mode decision in a network having a plurality of mobile stations (MS) communicably coupled to the base station (BS), the base station comprising:

• a mode decision module associated with the BS, the mode decision module comprising one or more processors configured to:
• select a first mode configuration for use during transmission of a first communication from the BS;
• and
• receive first feedback information comprising a first mode recommendation and first channel information from at least one of the plurality of MS;
• wherein the mode decision module includes:
• a state identification sub-module comprising one or more processors to identity a first system state of the first communication based at least in part on the first channel information;
• and
• a state transition sub-module comprising one or more processors to determine whether to transition from a prior system state to the first system state based on one or more transition conditions, and transition from the prior system state to the first system state,
• wherein the one or more processors of the mode decision module are further configured to:
• determine whether to use the first mode recommendation based at least in part on the first system state and satisfaction of at least one of the one or more transition conditions;
• and
• responsive to the determination, configure a second communication using a second mode configuration selected between a BS-derived mode based upon system-level information and an MS-mode recommendation based upon channel information so as to adaptively change the system state as channel condition or network condition change over time.

• responsive to the determination, configure a second communication using a second mode configuration selected between a BS-derived mode based upon system-level information and an MS-mode recommendation based upon channel information so as to adaptively change the system state as channel condition or network condition change over time.

A computer-implemented method for a hybrid scheme of mode decision in a network having a plurality of mobile stations (MS) communicably coupled to a base station (BS), the method comprising:

• selecting, by the base station, a first mode configuration for use during transmission of a first communication from the base station;
• receiving, by the base station, first feedback information comprising a first mode recommendation and first channel information from at least one of the plurality of MS;
• identifying, by the base station, a first system state of the first communication based at least in part on the first channel information;
• determining, by the base station, whether to transition from a prior system state to the first system state based on one or more transition conditions, and transitioning from the prior system state to the first system state;
• determining, by the base station, whether to use the first mode recommendation based at least in part on the first system state and satisfaction of at least one of the one or more transition conditions;
• and
• responsive to the determination, configuring, by the base station, a second communication using a second mode configuration selected between a BS-derived mode based upon system-level information and an MS-mode recommendation based upon channel information so as to adaptively change the system state as channel condition or network condition change over time.
