A PDCH may be full rate, double rate or triple<br \/>\nrate. The MAC, Radio Resource Management Entity (RRME) [4] and<br \/>\nBroadcast Management Entity (BME) comprise the Radio Resource (RR)<br \/>\nsublayer in the General Packet Radio System-136 (GPRS-136) protocol<br \/>\nstack. The MAC entity supports two multiplexed MAC Logical Links<br \/>\n(MLL) of different priorities. The first MLL is assigned higher<br \/>\npriority and provides the higher layer and various management<br \/>\nentities with expedited data delivery services. The other MLL is<br \/>\nused for normal data transfer.<\/p>\n<p>The MAC Entity is responsible for in-sequence delivery of normal<br \/>\ndata and expedited data provided to it by the higher layer. Both<br \/>\nunacknowledged and acknowledged modes are supported on the<br \/>\ndownlink. Acknowledged mode is supported on the uplink. In<br \/>\nacknowledged mode, error recovery is handled using a sliding window<br \/>\nARQ protocol.<\/p>\n<p>The MAC entity at the base station is responsible for active<br \/>\nmobile identity management (i.e., assignment and release of<br \/>\ntemporary local identifiers for mobiles engaged in data<br \/>\ntransmission or reception). These identifiers are used to carry out<br \/>\nacknowledgment and assignment functions for uplink transmissions<br \/>\nand to identify the recipient of data on the downlink. The base<br \/>\nstation MAC entity also controls phase assignments (i.e., it can<br \/>\norder mobiles to look for uplink assignments and listen for<br \/>\ndownlink transmissions on specific time slots).<\/p>\n<p>On the uplink, both contention and reservation based access are<br \/>\nsupported. Active Mobile Identity (AMI) values are used to provide<br \/>\nacknowledgments to contending users and to identify time slots as<br \/>\ncontention slots or slots reserved for a specific mobile<br \/>\nstation.<\/p>\n<p>Each ARQ mode transaction starts with the transmission of a<br \/>\nBEGIN Protocol Data Unit (PDU) and proceeds with the transmission<br \/>\nof CONTINUE PDUs. The BEGIN handshake establishes the AMI for the<br \/>\ntransaction and the mode of operation (i.e., fixed coding or<br \/>\nincremental redundancy) for the transfer of subsequent CONTINUE<br \/>\nPDUs. A variable number of blocks may be packed into each CONTINUE<br \/>\nPDU depending on the modulation. ARQ Status PDUs are used to<br \/>\nprovide the peer transmission controller with knowledge about the<br \/>\nreceiver state.<\/p>\n<p>The MAC entity consists of a number of internal functional<br \/>\nentities to carry out the above functions. These entities exchange<br \/>\ninformation through a set of primitives. The functional entities<br \/>\nwithin the MAC entity are as follows:<\/p>\n<ul>\n<li>MAC Logical Link Discriminator<\/li>\n<li>Transmit buffer for each MLL.<\/li>\n<li>Stuffer.<\/li>\n<li>Frame Extractor<\/li>\n<li>Broadcast Controller<\/li>\n<li>Point to Multipoint Controller<\/li>\n<li>Transmission Controller for each MLL:<\/li>\n<li>The transmission controller consists of the following<br \/>\nfunctional entities:<\/li>\n<li>Transmit Controller.<\/li>\n<li>Receive Controller.<\/li>\n<li>Router.<\/li>\n<li>PDU Encoder for each MLL.<\/li>\n<li>PDU Decoder for each MLL.<\/li>\n<li>Incremental Redundancy Segment Encoder (for MLL1 only).<\/li>\n<li>Incremental Redundancy Segment Decoder (for MLL1 only).<\/li>\n<li>Channel Access Manager (CAM).<\/li>\n<li>Sub-channel Controllers (SCCs).<\/li>\n<li>MAC Layer Controller (MLC).<\/li>\n<\/ul>\n<p>The types of signals defined within the MAC entity include the<br \/>\nfollowing(detailed definitions are in Section 5):<\/p>\n<ul>\n<li>MAC SDUs received from higher layer entities.<\/li>\n<li>MAC Stuffed SDUs that add protocol identification and framing<br \/>\nto MAC SDUs.<\/li>\n<li>MAC Data Segments used by Transmission Controllers as units of<br \/>\ndata recovery.<\/li>\n<li>MAC PDUs for communication between peer Transmission<br \/>\nControllers.<\/li>\n<li>Service primitives for providing service to the higher layer<br \/>\nand various management entities, for communicating between<br \/>\nfunctional entities within the MAC, and for obtaining service from<br \/>\nthe physical layer.<\/li>\n<\/ul>\n<p>Detailed PDU formats are provided for transfer of paging, data<br \/>\nand supervisory information on the downlink and data and<br \/>\nsupervisory information on the uplink. Models for both mobile<br \/>\nstation and base station operation are provided. Detailed diagrams<br \/>\ndescribing states, state variables and state transitions are<br \/>\nprovided using Specification and Description Language (SDL).<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>TDMA &#8211; Third Generation Wireless &#8211; Packet Data Service &#8211; 136+ Medium Access Control<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/tia\/\"><b>TIA<\/b><\/a><\/td>\n<td>2000<\/td>\n<td>236<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":690876,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2646],"product_tag":[],"class_list":{"0":"post-690867","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-tia","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/690867","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/690876"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=690867"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=690867"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=690867"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
