1. A method for performing traffic flow management in a wireless communications system with aid of auxiliary information, the wireless communications system comprising a first device and a second device, the method being applicable to the first device, the method comprising:
carrying first auxiliary information in at least one first data unit of first data units in a first stream, wherein the first stream and a second stream are assigned to a same traffic identifier (TID); and
sending the at least one first data unit carrying the first auxiliary information and at least one second data unit in the second stream to the second device, wherein the first auxiliary information comprises an indication of the first data units being part of the first stream;
wherein the first stream is a first stream classification service (SCS) stream, wherein the indication in the first auxiliary information comprises a first SCS identifier (SCSID); the first device is arranged to send the at least one first data unit carrying the first SCSID to the second device, to allow the second device to identify the at least one first data unit belonging to the first SCS stream among multiple data units buffered in a reordering buffer of the second device; and the first auxiliary information carried by the at least one first data unit further comprises a buffering indication of the first SCS stream, and the buffering indication of the first SCS stream indicates whether a first buffer flush request is sent by the first device, wherein the first buffer flush request allows the second device to flush out the buffered first data units.
