1. A data reordering method performed by a receiving apparatus, comprising:
receiving a first physical layer (PHY) protocol data unit (PPDU) from a transmitting apparatus, wherein the first PPDU comprises a plurality of medium access control (MAC) PDUs (MPDUs), and the MPDUs correspond to the same block acknowledgement (BA) window;
determining a traffic that each of the MPDUs belongs to according to an MPDU identification, wherein traffics that the plurality of MPDUs belonging to comprise a first traffic and a second traffic which is different from the first traffic;
performing a reordering operation for the MPDUs belonging to the first traffic, and a reordering operation for the MPDUs belonging to the second traffic, respectively; and
transmitting a block acknowledgement (BA) frame in response to the first PPDU to the transmitting apparatus, wherein the BA frame comprises information for indicating whether the MPDUs in the first PPDU have been successfully received;
wherein there is at least one frame check sequence (FCS) error in the first traffic, the step of performing a reordering operation for the MPDUs belonging to the first traffic comprises:
maintaining a first last-arrived-SN corresponding to the first traffic as the last sequence number (SN) of the MPDUs of the first traffic that are prior to the MPDU with an FCS error of the first traffic if the MPDU with the FCS error of the first traffic is not received successfully; and
buffering at least one MPDU of the first traffic, wherein the SN of the at least one MPDU of the first traffic is later than the first last-arrived-SN corresponding to the first traffic.
