CHANNEL QUALITY INDICATOR DESIGN FOR MULTIPLE-USER MULTIPLE-INPUT AND MULTIPLE-OUTPUT IN HIGH-SPEED PACKET ACCESS SYSTEMS
摘要
A method for providing multiple-user multiple-input and multiple-output in a high-speed packet access system is described. A channel quality indicator is received from a dual-stream-capable wireless communication device requesting a single-stream transmission at a first data rate. The first data rate is adjusted by an adaptive outer loop margin to obtain a second data rate. A data stream is transmitted to the wireless communication device using the second data rate. A positive-acknowledgement/negative-acknowledgement (ACK/NACK) is received from the wireless communication device. The adaptive outer loop margin is adjusted according to the received ACK/NACK.
