The AT receives reverse activity bits (RABs) from one or more radio nodes via one or more forward-link channels. The AT determines a reverse-activity-indicator from the RABs and determines whether the reverse-activity-indicator indicates that reverse activity on a reverse-link being monitored by the AT or being used by the AT to carry out reverse-link communications exceeds a threshold level of activity. If the reverse-activity-indicator indicates that reverse activity exceeds the threshold level of activity, then the AT transitions to or continues operating in a MIMO reverse-link mode, otherwise, if the reverse-activity-indicator indicates that reverse activity does not exceed the threshold level of activity, then the AT transitions to or continues operating in a non-MIMO reverse-link mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for access terminal transition between a MIMO reverse-link mode and a non-MIMO reverse-link mode","description":"A method and access terminal (AT) are provided for switching operation of the access terminal between a multiple-input multiple-output (MIMO) reverse-link mode and a non-MIMO reverse-link mode.
