Feedforward of non-quantized precoding weights in a wireless communications system
Abstract:
An apparatus and method to feedforward non-quantized precoding weights in an OFDM communication system includes a first step (300) of sending feedback information from a subscriber station (SS) to a base station (BS). A next step (302) includes deriving non-quantized weight information from the feedback information. A next step (304) includes transmitting symbols carrying the non-quantized weight information and non-precoded pilot symbols by the BS. A next step (305) includes receiving the information and symbols by the SS. A next step (306) includes estimating the non-quantized weights from the symbols carrying the non-quantized weight information and the non-precoded pilot symbols by the SS. A next step (308) includes decoding data from the BS by the SS using the estimated non-quantized weight information.
