SYSTEM AND METHOD FOR TRANSMITTING CONTROL INFORMATION IN AN UPLINK MULTIPLE INPUT MULTIPLE OUTPUT TRANSMISSION

摘要

Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In particular a primary stream (610) may be utilized to carry a primary data channel E DPDCH (624) and a secondary stream (612) may be utilized to carry a secondary data channel S E DPDCH (620). Further the primary stream (610) may be precoded utilizing a primary precoding vector and the secondary stream (612) may be precoded utilizing a secondary precoding vector with coefficients orthogonal to those of the primary precoding vector. The primary stream may include an enhanced control channel E DPCCH (614) adapted to carry control information associated with both the primary data channel E DPDCH (624) and the secondary data channel S E DPDCH (620).
