摘要:
Methods, apparatuses, and computer program products are disclosed for facilitating decoding a communication received from a wireless terminal. Encoded bits are received from the wireless terminal via a shared uplink channel, and a plurality of acknowledgment tones are identified within the encoded bits. A correlation value is ascertained corresponding to a correlation between detected bits within the plurality of acknowledgment tones and valid bits corresponding to any of a plurality of valid acknowledgment codewords. A determination is then made as to whether the plurality of acknowledgment tones includes information corresponding to a discontinuous transmission by comparing the correlation value to a threshold value.

Systems, methods, and devices for performing channel estimates to address the Doppler Effect in wireless communications are described herein. One aspect of the disclosure provides an apparatus for wireless communication. The apparatus comprises a receiver configured to receive coded data tones during a first symbol over a communication channel. The apparatus further comprises a processor. The processor is configured to estimate a common phase offset and amplitude of the communication channel based on pilot tones received over the communication channel. The processor is configured to determine, prior to decoding, a residual phase offset per data tone based on a phase difference between an estimate of the coded data tones and a reference symbol. The processor is configured to estimate update channel state information of the communication channel based on the determined estimated common phase offset, amplitude, and the determined residual phase offset per data tone.
