    摘要: According to an example embodiment, a method may include allocating, within a single physical resource unit (PRU), a plurality of channel sounding groups. Wherein each channel sounding group includes a frequency-time domain code division multiplexing (CDM) allocation. The method may also include broadcasting, in a downlink direction to one or more mobile stations in a wireless network, a signal that causes the receiving mobile stations to transmit a channel sounding signal. The method may further include receiving at least one channel sounding signal from at least one of the one or more mobile stations, the channel sounding signal being received in an uplink direction via one or more channel sounding groups. And, the method may include estimating the channel quality, of the channel used by the physical resource unit, based upon the received at least one channel sounding signal.

    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.
