摘要： M physical resource blocks PRBs are allocated for localized resource allocation LRA and N−M PRBs are allocated for distributed resource allocation DRA. Each PRB has U subcarriers. Subcarriers of the N PRBs are permuted to result in N subchannels. Serially for each mth one of the M PRBs allocated for LRA, the subcarriers for an mth one of the M PRBs allocated for LRA are punctured from the permuted subchannels. After puncturing, subcarriers of one of the subchannels are filled with subcarriers of all other subchannels which were punctured in the mth one of the M PRBs. The result after puncturing and filling for all M PRBs allocated for LRA is N−M PRBs each having U subcarriers and M PRBs each having U subcarriers. Then there is a wireless communication using at least one of a LRA on the resulting M PRBs or a DRA on the resulting N−M PRBs.
