Method and apparatus for receiving a medium access control protocol data unit having a fragmentation and packing extended header

摘要

The present invention relates to a method in which a receiver receives an MAC (medium access control) PDU (protocol data unit) in a wireless communication system. The method in which the receiver receives an MAC PDU comprises the following steps: receiving an MAC PDU containing a header and a payload from a transmitter, wherein the header includes a first extended header containing a first length field which indicates the length of a service data unit (hereinafter, referred to as “SDU”) or lengths of fragmented SDUs in the MAC PDU; decoding the header; and determining whether the size of the first length field in the extended header is an extended size or a basic size in accordance with the results of decoding.

1. A method for receiving a medium access control (MAC) protocol data unit (PDU) by a receiver in a wireless communication system, the method comprising:
receiving the MAC PDU from a transmitter, the MAC PDU including a header and a payload, wherein the header includes a fragmentation and packing extended header (FPEH) containing:
a first length field indicating a length of a service data unit (SDU) or lengths of fragmented SDUs in the MAC PDU, anda first length indicator indicating the size of the first length field; decoding the header by checking the first length indicator; and when the first length indicator indicates an extended size, determining whether the size of the first length field in the FPEH is the extended size.
