Abstract:
Aspects of the present disclosure include methods, apparatuses, and computer readable media for identifying an initial rank, modulating information into a first plurality of layers associated with the initial rank, scrambling the first plurality of layers by a first common scrambler to generate a first plurality of scrambled layers, transmitting, to the receiver, the first plurality of scrambled layers, receiving an indication of failed demodulation of a portion of the first plurality of scrambled layers, modulating at least a portion of the information into a second plurality of layers, wherein the second plurality of layers includes a same number of layers as the first plurality of layers, scrambling the second plurality of layers by a second common scrambler to generate a second plurality of scrambled layers, and transmitting, to the receiver, the second plurality of scrambled layers.
