title = "Throughput of Hybrid ARQ Types for UTRA TDD mode",
abstract = "A throughput analysis of ARQ Types I and II-III based on simulations for unconstrained delay data (UDD) services is presented. We emphasise differences between Types I and II and consider Types II and III as minor variants of the same scheme which we call {"}Type II-III{"} for the purpose at hand. For this contribution, a subset of the protocol on Layers 1-3 for UMTS terrestrial radio access (UTRA) time division duplex (TDD) mode is simulated for a single cell. Both user traffic and signalling messages suffer from path-loss, fading, and interference in the model. Interference due to traffic in neighbouring cells is also taken in to account through the {"}actual value interface{"}. Results are obtained for downlink traffic for various code-rates and interleaving schemes. The available results include capacity, signalling overhead, the distribution of the number of retransmissions, and PDU delay. It is shown that Type II-III greatly outperforms Type I for the cases {"}UDD 2048 Pico{"} and {"}UDD 384 Micro{"} in terms of capacity and the number of retransmissions. Although, the benefit of using Type II-III over Type I becomes smaller at lower bit rates it is still significant. This is exemplified by simulation results for the case {"}UDD 8 Micro{"}. We conclude that Hybrid ARQ Type II-III outperforms Type I for all UDD services between 8 kb/s and 2 Mb/s for UTRA TDD mode.",
