SYSTEM AND METHOD FOR INCREASING CAPACITY SECONDARY control channel during the transmission of a multiple-input multiple-output uplink

摘要

Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In particular, an enhanced pilot reference may be provided for enabling increased data rates on a secondary stream. Specifically, a primary stream, provided on a primary virtual antenna (610), includes an enhanced primary data channel E-DPDCH (624), a primary control channel DPCCH (622), and an enhanced primary control channel E-DPCCH (614). Further, a secondary stream, provided on a secondary virtual antenna (612), includes an enhanced secondary data channel S-E-DPDCH (620) and a secondary control channel S-DPCCH (618). Here, the secondary control channel S-DPCCH (618) may be transmitted at a boosted power level relative to a determined reference power level.
