Subcarrier mapping techniques for guard interval-based orthogonal frequency division multiplexing communications
摘要
說明書
In some examples, to support receiving the configuration information, the configuration manager 1145 may be configured as or otherwise support a means for receiving one or more parameters for determination of the permutation matrix via RRC signaling, a medium access control (MAC) control element, DCI, or any combinations thereof. In some examples, the first number of columns of the sub-matrix are selected as quasi-equidistant columns from a total number of columns of the first matrix. In some examples, the first matrix is a product of the IFFT matrix and a sub-carrier mapping matrix, and the sub-matrix includes columns of the first matrix that correspond to a subset of active subcarriers for the OFDM symbol that do not include guard subcarriers associated with a guard band of the OFDM symbol. In some examples, the first matrix corresponds to the IFFT matrix, and the sub-matrix includes columns of the first matrix that correspond to all subcarriers for the OFDM symbol including guard subcarriers associated with a guard band of the OFDM symbol, and one or more columns of the sub-matrix that are associated with the guard subcarriers are discarded.
