Abstract
A system and method for adding a burst of a single-input multiple-output mode or collaborative spatial multiplexing mode to a frame in a spatial multiplexing system. A base station is configured to add a burst of a single-input multiple-output mode to a frame in a spatial multiplexing system. The system and method includes backing up a pilot pattern and a number of slots allocated for connections with terminals; releasing slots allocated for a burst; resetting a pilot pattern of a collaborative spatial multiplexing mode burst of the terminals: and recalculating the number of remaining slots; comparing the number of slots that can be additionally allocated to the single-input multiple-output mode with the number of slots released in the releasing step; and determining a transmission format.
