34、ord This Technical Specification (TS) has been produced by ETSI Project Broadband Radio Access Networks (BRAN). The present document describes the basic data transport functions of the Data Link Control (DLC) of HIgh PErformance Radio Local Area Network Type 2 (HIPERLAN/2) systems. Separate ETSI doc

35、uments provide details on the system overview, physical layer, radio link control sublayer, convergence sublayers and conformance testing requirements for HIPERLAN/2. The present document is part 1 of a multi-part deliverable covering the HIPERLAN Type 2; Data Link Control (DLC) Layer, as identified

36、 below: Part 1: Part 2: Part 3: “Basic Data Transport Functions“; “Radio Link Control Sublayer“; “Extension for Business Environment“; Part 4: “Extension for Home Environment“; Part 5: “Profile for Home Environment“. Introduction HIPERLAN/2 is confined to the functions, which are located in the two

37、lowest layers of the open systems interconnection (OSI) model, the physical and the data link control layers. The HIPERLAN/2 specifications also define some functionalities related to the network layer in the OS1 model. The HIPERLAN/2 system overview document, TR 101 683 6, contains an overall descr

38、iption of the HIPERLAN/2 system. Extensions for different applications of the DLC are specified in other HIPERLAN/2 DLC extension technical specifications (see Bibliography). The radio link control (RLC) sublayer 5 contains functions for radio resource control, association control and connection con

39、trol. 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 specifications (see TS 101 493 and TS 101 763 in Bibliography). The specification of a management information bas

40、e is described in TS 101 763 (see Bibliography). ETSI 8 ETSI TS 101 761-1 V1.2.1 (2000-11) 1 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 fol

41、lowing parts of the DLC layer: Error Control, Medium Access Control (MAC) and the mapping between the PHY and the MAC layers of HIPERLAN/2.The present document does not address the requirements and technical characteristics for type approval and conformance testing. These are covered in separate Tec

47、previous MAC frame is conveyed Access Point (AP): device that is responsible for the centralized control of the resources in a radio cell. It is usually connected to a fixed network Association Control Function (ACF): group of control functions that uses the services of the RLC. These functions are

48、responsible for the handling of the association between MT and AP Association control CHannel (ASCH): logical channel in the uplink that conveys new association and re-association request messages Broadcast CHannel (BCH): transport channel that broadcasts control information ETSI 9 ETSI TS 101 761-1

49、 V1.2.1 (2000-11) Broadcast Control CHannel (BCCH): logical channel that broadcasts control information which is relevant for the current MAC kame Central Controller (CC): provides control functionality equivalent to that of an access point but is not necessarily attached to a fixed network. This term is normally used if central controller and MT functionality are located in a single device. It mostly involves direct mode communication Centralized Mode (CM): in centralized mode, all data transmitted or received by a mobile terminal pass the access point or the centralized cont
