Abstract A novel analytical framework is presented to evaluate capacity and error ratio of different protocol layers in 3GPP LTE systems. Signal flow graphs are used to model various aspects: On PHY layer, association of user terminal to a radio access point, probabilistic radio channel states, adaptive modulation and coding, overhead in LTE radio frame, turbo coded M-QAM block error rate, and Chase combining are taken into account. On MAC layer, hybrid-ARQ, resource assignment failure, and feedback misdetection are accounted for. On RLC layer, segmentation, selective repeat - ARQ, feedback loss, and timer for upcoming feedback are considered.
