Abstract:
A method comprising: receiving first information at a user equipment, storing at least some of the received first information at the user equipment; in response to incorrect decoding of at least some of the received first information by the user equipment, receiving second information at the user equipment, the second information comprising a hybrid automatic repeat request (HARQ) re-transmission of at least some of the first information, and the second information further comprising a scheduling allocation, the scheduling allocation comprising scheduling information of the received first information; and using the scheduling allocation, by the user equipment, to perform soft-combining of the stored first information and the received re-transmission of at least some of the first information.
Abstract:
Systems, methods, apparatuses, and computer program products for generating sequences for zero-tail discrete fourier transform (DFT)-spread-orthogonal frequency division multiplexing (OFDM) (ZT DFT-s-OFDM) reference signals. One method includes adding a zero vector to an input sequence, and performing an iterative manipulation of the input sequence. The performing of the iterative manipulation of the input sequence may include, for example: computing frequency domain response of the sequence, normalizing elements of the computed frequency domain sequence to unitary power while maintaining phase of each of the elements, converting the sequence to time domain, generating a zero-padded sequence by forcing a zero head and tail of the sequence, and repeating the steps until a final sequence with zero-tail and flat frequency response is obtained.
