Abstract:
1. A method for transmitting an acknowledgement/negative acknowledgement, comprising: generating a cell-specific cyclic shift; applying cell-specific symbol-level phase hopping to single-carrier frequency division multiplexing data symbols of the acknowledgement/negative acknowledgement, wherein the cell-specific symbol-level phase hopping is based at least in part on the cell-specific cyclic shift; applying cell-specific symbol-level cyclic shift hopping to the single-carrier frequency division multiplexing data symbols of the acknowledgement/negative acknowledgement, wherein the cell-specific symbol-level cyclic shift hopping is based at least in part on the cell-specific cyclic shift; applying a discrete Fourier transform to the single-carrier frequency division multiplexing data symbols; and transmitting the single-carrier frequency division multiplexing data symbols in a slot.
