摘要： A method is described herein that enables a Selective-Per-antenna-RateControl (S-PARC) technique to be effectively implemented in a wireless communications network (e.g., HSPDA third generation communications network). In one embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a "full" feedback signal to a base station that analyzes the "full" feedback signal and determines which mode and transmission rates(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device. In another embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a "reduced" feedback signal to a base station that analyzes the "reduced" feedback signal and determines which mode and transmission rate(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device.
