3 Mar 2005 The internal configuration of MAC is done by the RRC layer (L3). The interface between PHY and MAC are the transport channels where as the interface between RLC and MAC are the logical channels. MAC provides services to both User plane as well as Control plane. UMTS/GPRS protocol architecture 3GPP TS 23.002: UMTS network architecture (CN and AN entities) and procedures .. MAC protocol controls the access. 21 Jul 2010 Data Link layer RRC, RLC, MAC, and PHY [Under UMTS] MAC, and PHY from UE point of view (refer diagram from article on radio layers). UMTS protocol stack consists of Access Stratum(AS) and Non Access Stratum(NAS). Access Stratum supports OSI-layer 1 to 3. It consists of PHY(layer 1), MAC(layer 2),RLC(layer 2) and RRC(layer 3). NAS or core network part is divided based on circuit switched(CS) or packet switched(PS) functionalities. 20 Jul 2010 MAC PDU [Under UMTS] Radio interface layer - 25.301 « In addition to RNTI, MAC header has information related to mapping of multiple In the user plane, in addition to MAC and RLC, two additional service-dependent protocols exist: the Packet Data Convergence Protocol (PDCP) and the Broadcast/Multicast Control (BMC) protocol. Layer 3 consists of one protocol, called the Radio Resource Control (RRC), which belongs to the control plane. L2/MAC. L1. MAC. PHY. PDCP. UMTS Protocols and Protocol Testing. Primer v. 13 .. ETSI ETR 021. Advanced Testing Methods (ATM); Tutorial on protocol.5 Aug 2014 This tutorial describes the specific details of the LTE MAC layer or the Channel structure in LTE is similar to that of UMTS but it is much looks at UMTS measurement and testing where tutorial participants will find real-world Medium Access Control (MAC) [3G TS 25.321]—The MAC layer. 23 Mar 2012 Medium Access Control (MAC) in 3G,UMTS Protocol Stack_????_????_?????Tutorial: Medium Access Control (MAC) in 3G/UMTS
