Compressed header - structure in the case of the media access controller (mac - medium access control) for the reduction of the mac - have in common the expense in mobile systems with worldwide interoperability for microwaves access (wimax)

摘要

Packet data structure, which on one of a computer readable medium is stored, in order to said common outlay in terms of the media access controller (mac – medium access control) so as to reduce the packet data structure:a compressed according to directing head structure for the media access controller (mac), which a field for a compact connection - an identifier (ccid – compact connection identifier), said ccid - field, a ccid - value with m bits for identifying a compound comprising a unidirectional logical connection between a base station and a mobile station either in a forward connection direction or in reverse connection direction, wherein the ccid - value with m bits has a smaller number of bits as a connection identifier (cid – connection identifier) for a general mac - header (gmh – generic mac header) or a band widths request (bw - req – bandwidth request) - header and the ccid - value with m bits of a lsb (least significant bit) - part of a cid, wherein the use of the compressed mac - of directing head structure before establishing a connection between the base station and the mobile station using a type length value (tlv - type length value) is signalled, the in one or more dsa (dynamic service flow addition) - messages contain, and wherein the compressed mac - of directing head structure for use exclusively in one or more permutation zones is determined.
