UMTS MAC Layer


Brief Description

Project was
· To develop the MAC layer of the UMTS protocol stack complying with 3gpp specifications 25.321 (release 6).
· To develop a test suite to simulate the RLC, RRC and PHY layers to test the MAC functionality.

We designed and developed the various modules the MAC layer would need to perform uplink and downlink. The MAC layer constituted of various modules to perform various operations like processing the data coming in from the higher layers and adding the required headers, performing a transport format combination selection, decoding the transport format indicator received, controlling transmissions on the RACH transport channel, transmission, reception of the various primitives, mapping of the logical channel on to the physical ones and traffic monitoring.

The test suite constituted of the simulated RLC RRC and PHY layers and ran as a separate process .The communication between the test suite and the MAC layer was achieved using the interprocess communication mechanisms. Testing scenarios were determined after studying User Equipment (UE) conformance specification 3GPP TS 34.123-1, 3GPP TS 34.123-2, 3GPP TS 34.123-3.
