Abstract: A method of beacon reception for a communication device in a wireless communication system is disclosed. The method comprises starting to receive a beacon from an access point (AP) of the wireless communication system, determining whether a specific element of the beacon is received, and determining whether to receive only a portion of the beacon according to the specific element.

Abstract: Aspects of the disclosure provide a method for reordering. The method includes receiving, by a terminal device, a stream of data units from a wireless network. The data units have respective sequence numbers. Further, the method includes reordering at a protocol layer in a protocol stack, the data units for a next process according to the sequence numbers, determining a dependency relationship of a data unit to one or more missing data units that have sequence numbers prior to the data unit, and advancing, out of order of the sequence numbers, the data unit to the next process when the data unit is independent of the one or more missing data units.
