scope:

The present document specifies the first phase of the basic data transport mechanism of the Data Link Control layer (DLC) of the HIPERLAN/2 system. It describes the technical characteristics of the following parts of the DLC layer: Error Control, Medium Access Control (MAC) and the mapping between the PHY and the MAC layers of HIPERLAN/2.HIPERLAN/2 is confined to the functions which are located in the two lowest layers of the open systems interconnection (OSI) model, the physical and the data link control layers. The HIPERLAN/2 also defines some functionalities related to the network layer in the OSI model. The HIPERLAN/2 system overview document, TR 101 683 [6], contains an overall description of the HIPERLAN/2 system.

Extensions for different applications of the DLC are specified in other HIPERLAN/2 DLC extension technical specifications. The radio link control (RLC) sublayer contains functions for radio resource control, association control and connection control. It is specified in another HIPERLAN/2 technical specification. The interworking with higher layers is handled by convergence layers on top of the data link control layer. Packet and cell based convergence layers are defined in other HIPERLAN/2 technical specifications. The specification of a management information base will be described in a different HIPLERAN/2 specification.

The present document does not address the requirements and technical characteristics for type approval and conformance testing. These are covered in separate Technical Specifications.
