Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Broadband Radio Access Networks (BRAN). The present document des
36、cribes the supplemental data transport and radio control functions of the Data Link Control (DLC) of HIgh PErformance Radio Metropolitan Area Network (HiperMAN) systems. A separate ETSI document, TS 102 177 2, specifies the Physical (PHY). With permission of IEEE(on file as BRAN43d016), portions of
37、the present document are excerpted from IEEE 802.16 1 and IEEE 802.16e 3. ETSI ETSI TS 102 178 V1.5.1 (2010-05)81 Scope The present document defines the Data Link Control (DLC) of HiperMAN to support PMP and optionally Mesh network topologies. The present document provides the DLC functions required
38、 for Fixed applications, in frequencies below 11 GHz, and Nomadic and converged Fixed-Nomadic applications, in frequencies below 6 GHz. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

45、viations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: Adaptive Antenna System (AAS): system adaptively exploiting more than one antenna to improve the coverage and the system capacity NOTE: AAS-enabled in the context of a PMP BS denotes the imp
46、lementation of AAS as defined. AAS-enabled in the context of a PMP SS denotes the ability to communicate with an AAS-enabled BS using the AAS specific mechanisms. Though a PMP SS may itself implement AAS as defined, this has no impact on the air interface and hence no specific differentiation is mad
47、e. adaptive modulation: systems ability to communicate with another system using multiple burst profiles and a systems ability to subsequently communicate with multiple systems using different burst profiles ARQ Block: distinct unit of data that is carried on an ARQ-enabled connection NOTE: Such a u
48、nit is assigned a sequence number, and is managed as a distinct entity by the ARQ state machines. bandwidth stealing: use, by a subscriber station operating on a grant per subscriber station basis, of a portion of the bandwidth allocated in response to a bandwidth request for a connection to send a
49、bandwidth request or data for any of its connections broadcast connection: management connection used by the Base Station (BS) to send Data Link Control (DLC) management messages on a downlink to all Subscriber Station (SS) NOTE: The broadcast connection is identified by a well-known Connection IDentifier (CID). A fragmentable broadcast connection is a connection that allows fragmentation of broadcast DLC management messages. connection: unidirectional mapping between Base Station (BS) and Subscriber Station (SS) Data Link Control (DLC) peers NOTE: Connecti
