Abstract: A wireless communication device includes an aggregation circuit, a processing circuit and a transmitter. The aggregation circuit is arranged to execute an aggregation operation to generate a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU). The processing circuit is coupled to the aggregation circuit and arranged to generate a first indicator indicating a length of the PPDU and include the first indicator into a first field in a preamble of the PPDU. The transmitter is coupled to the processing circuit and arranged to transmit the PPDU to an access point.
