Abstract
Provided are a transmission/receiving apparatus and method of switching a transmission antenna in a Transmission Switched Diversity (TSD) system. The transmission apparatus includes an announcement command frame reading unit to verify a TSD Information Element (IE) included in an announcement command frame when receiving the announcement command frame from a receiving apparatus, and to verify whether to request a switching of the transmission antenna, an antenna switching unit to select an antenna, not being selected from a plurality of antennas, as a transmission antenna when the announcement command frame requests the switching of the transmission antenna, and to switch a currently used antenna into the selected transmission antenna, and an announcement command frame generation unit to convert transmission antenna information included in the TSD IE into the selected transmission antenna, and to generate a response announcement command frame including the converted TSD IE and transmit to the receiving apparatus.
