PRBSET
包含与此PDSCH传输的资源分配相对应的物理资源块(PRB)索引。您可以指定PRBSET
as either a column vector or a two-column matrix. If you specify a column vector, the resource allocation is the same in both slots of the subframe. If the PRBs in the first and second slots of the subframe differ, you can use the two-column matrix to specify PRBs. The PRB indices are zero-based.
Each column of the returnedn-by-p矩阵,,,,ind
