摘要：
A method for receiver processing in a 3GPP Long Term Evolution (LTE) receiver processing chain in a wireless mobile device is provided. LTE initial sub-frame transmitted from a base station is received on a LTE signalling channel. The sub-frame is received using a basic receiver. An integrity check is performed to determine if the sub-frame was demodulated and decoded correctly by the basic receiver. An advanced receiver is enabled prior to receiving an expected retransmission sub-frame based upon the integrity check failing and a hybrid-acknowledgement request (HARQ) negative acknowledgement (NAK) being sent by the wireless mobile device. The retransmission sub-frame is received using the advanced receiver. The basic receiver is enabled when the integrity check of the retransmission sub-frame passes and a acknowledgement (ACK) is by the wireless mobile device or a new data indicator (NDI) is set in a control channel indicating that the transmission is an initial transmission.
