20、specifies a Medium Access Control function that layer-3 functions and radio resource functions may use to transport data octets across a TDMA radio interface.MAC supports two multiplexed MAC Logical Links of different priorities. The MAC provides in sequence delivery of normal data and expedited dat
21、a provided to it by the higher layer. Both unacknowledged and acknowledged modes are supported on the downlink. Acknowledged mode is supported on the uplink. In acknowledged mode, error recov-ery is handled using a sliding window ARQ protocol.TIA/EIA-136-332 was developed by TR-45.3.2, the Data Serv
22、ices Working Group of TR-45.3, the TIA TDMA Wire-less Standards Subcommittee.TIA welcomes suggestions for improvement of this standard. Please send suggestions to the following address:Telecommunications Industry Association2500 Wilson Boulevard - Suite 300Arlington - VA 22201-3836This standard cont
23、ains two annexes: Annex A contains normative text defining half-duplex operation. Annex B contains normative definitions of SDL symbols used within this standard.This standard contains Appendix A contains no requirements, just a description of fixed coding mode transactions. Appendix B contains no r
24、equirements, just a description of Packet Channel Feedback procedures. Appendix C contains no requirements, just descriptions of transaction initiation, completion and abort pro-cedures. Appendix D contains no requirements, just a description of adaptive modulation. Appendix E contains no requiremen
25、ts, just a description of the incremental redundancy radio link protocol.As an aid to the first-time reader, the organization of this document in terms of text and SDL is presented below together with a suggested approach to reading the document, for obtaining either an overview or an in-depth under
26、-standing of the TIA/EIA-136 packet MAC.Document OrganizationThe document is divided into two separate parts, viz. a text part and an SDL part:Text:The textual part of the document consists of chapters 1 through 5 (normative), Annex A (normative) and Appendices A through E (informative). These can b
27、e read independent of the SDL part of the document (chapters 6, 7 and Annex B). They provide the first level of detail of the MAC by providing a functional-level description without going into the details of the internal entities of the MAC. Specifically, they cover the MAC internal/external archite
28、cture, signal flows, coding, transaction descriptions and various other incidental details. The Fixed Coding (FCM) and Incremen-tal Redundancy (IRM) specific text are presented in independent sections with headings that clearly indicate the applicable mode. Therefore readers may focus effort on the
29、sections with content relevant to their interestsSDL:The SDL part of the document consists - in its entirety - of chapters 6 (MS), 7 (BS) and Annex B (all normative). The SDLs are provided in addition to the text as a second level of detail by elaborating on the internals of the MAC. Each SDL corres
30、ponds to one of the internal functional entities of the MAC and is a separate section. It is not necessary to read the SDLs to understand the text part of the document. Each SDL section contains an overview of the SDL, a list (with descriptions) of the variables used in the SDL and finally the SDL f
31、lowcharts. The Fixed Coding (FCM) and TIA/EIA-136-332iiIncremental Redundancy (IRM) specific SDLs are presented independent of each other with headings that clearly indicate the applicable mode. Therefore readers may focus effort on the SDLs with content relevant to their interests.Suggested Approac
32、h to Reading the Document1. The text part of the document should be read first to get a thorough functional-level understanding of theMAC (chapters 1-5 except section 5.10, Annex A and Appendices A-E). Readers may focus effort on thesections with content relevant to their interests. 2. The SDLs may
33、be read next for additional in-depth understanding of the MAC and for comprehensive refer-ence purposes (chapters 6 and 7 and section 5.10). In the first pass, it is sufficient to read the text overview atthe beginning of each SDL section and then to roughly verify the SDL for correspondence with th
34、e over-view. Variable names are self-explanatory so the variable list may be used as a reference. Subsequent passesmay be performed in progressively greater detail as required.Note that there are substantial similarities between the corresponding MS and BS functional entities and also between the FC
35、M and IRM modes (the IRM-specific SDLs appear in the Transmission Controller and PDU Encoder/Decoder entities only). In addition, low-level details such as ARQ table management can be skipped in the initial passes through the SDLs.TIA/EIA-136-332iiiContents1 Introduction . . . . . . . . . . . . . .
