Foreword This Technical Specification (TS) has been produced by ETSI Project Broadband Radio Access Net

28、works (BRAN). The present document describes the extension of the basic specifications of Data Link Control (DLC) of HIPERLAN/2 systems for home applications. Separate ETSI documents provide details on the system overview, the physical layer, the basic DLC layer functions, the convergence sublayers

29、and the conformance test requirements defiied for HIPERLAN/2. The present document is part 4 of a multi-part deliverable covering the Broadband Radio Access Networks (BRAN); HIPERLAN Type 2; Data Link Control (DLC) Layer, as identified below: Part 1 : Part 2: Part 3 : “Basic Data Transport Functions

30、“; “Radio Link Control (RLC) sublayer“; “Profile for Business Environment“; Part 4: “Extension for Home Environment“; Part 5: “Profile for Home Environment“ I n t rod uct ion The H/2 system is confined to the two lowest layers of the open systems interconnection (OSI) model, the physical (PHY) and t

31、he Data Link Control (DLC) layer. An overall description of the HIPERLAN/2 system is given in TR 101 683 (see bibliography). The PHY layer is described in TS 101 475 3. The basic DLC layer functions are specified in two different documents (TS 101 761-1 i and TS 101 761-2 2). Document TS 101 761-1 i

32、 describes Transport and Logical Channels, Error Control, MAC, and mapping between PHY and MAC of H/2 system. Document TS 101 761-2 2 deals with Radio Link Control (RLC) protocols to control radio resources, terminal association and connection establishment. The inter-working with higher layers is h

33、andled by Convergence Layers (CLs) on top of the DLC layer. The common part of packet and cell based convergence layers are defiied in TS 101 493-1 and TS 101 763-1 (see bibliography), respectively. ETSI 7 ETSI TS 101 761-4 V1.3.2 (2002-01) 1 Scope The present document specifies the extension of the

34、 basic DLC layer functions in TS 101 761-1 i and TS 101 761-2 2 for direct mode operation in home environment. This DLC home extension specification gives first an overview of the HIPERLAN/2 home system concept. It then describes additional rules and elements to transport DM data over the channels i

35、ntroduced in TS 101 761-1 i. Forward Error Correction (FEC) is introduced in the DLC layer to achieve a much lower bit error rate for isochronous packet transport without ARQ. The present document also extends the RLC protocols in TS 101 761-2 2 to support Constant Bit Rate (CBR) traffic by fixed sl

36、ot allocation, to enable parameter negotiation for multicast connections, to enable association of multiple CLs for wireless terminals, and to enable Direct Link (DiL) Power Control. Furthermore, It describes some RLC protocols which are only specific for DM operation in home environment, such as Di

37、L Link Quality Calibration, Dynamic CC Selection, and CC Responsibility Handover. Besides, a PIN and time-window based authentication key distribution protocol is specified for HIPERLAN/2 Home Devices (H/2-HDs). The DM services can be used by the IEEE 1394 CL (TS 101 493-3 and TS 101 493-4 (see bibl

38、iography) for wireless bridging of different IEEE 1394 buses. The present document does not contain algorithms, which are only performed locally in a device, but describes rules and elements to transport data over the air interface. The goal is to provide interoperability between devices of differen

39、t manufacturers. The present document does not address the requirements and technical characteristics for conformance testing. These are covered in a separate set of documents. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of

40、the present document. References are either specific (identified by date of publication andor edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. il ETSI TS 101 761-1: “Broadband Rad

43、de in the random access phase of the previous MAC frame is conveyed Association Control Function: group of control functions on top of the RLC that is responsible for the handling of the association between WT and CC Association control CHannel: logical channel in uplink that conveys new association

44、 and re-association request messages ETSI 8 ETSI TS 101 761-4 V1.3.2 (2002-01) Access Point: term Access Point used in the basic specifications is replaced by the term Central Controller throughout TS 101 761-4 (V1.3.2) to reflect that in home environment multiple H/2 devices can act as the access p

45、oint to a fixed network, whereas the whole H/2 network is still controlled by a single entity, the Central Controller Basic WT: H/2 home device, which is able to associate with a CC and to communicate with the CC in the control plane and with other H/2 home devices in the user and control planes. A

46、basic WT is unable to become the CC. Broadcast CHannel: transport channel that broadcasts control information Broadcast Control CHannel: logical channel that broadcasts control information which is relevant for the current MAC frame CC-capable WT: H/2 home device, which can act either as a Central C

47、ontroller, or as a basic WT. When it is acting as the CC with respect to the control plane, it supports all features of a basic WT. Central Controller: provides control functionality equivalent to that of an access point in TS 101 761-1 and TS 101 761-2 but is not necessarily attached to a fixed net

48、work. This term is used where the central controller functionality is embedded in a WT. Centralized Mode: in centralized mode, all data transmitted or received by a mobile terminal have to pass the centralized controller, even if the data exchange is between mobile terminals associated to the same c

49、entralized controller DLC Connection: HIPERLAN/2 DLC operation is connection oriented. A DLC connection carries user or control data and is identified by a DLC connection identifier. DLC User Connection: DLC user connection is uniquely identified by the DLC connection ID and the MAC ID of the mobile terminal in CM. In DM two MAC IDS are necessary DLC User Connection Control: group of control functions on top of the RLC that is responsible for the handling of DLC user connections Downlink phase: part of the Downlink transmission of a MAC Frame during which user a
