نویسنده
چکیده
This paper deals with Radio Link Control protocol (RLC) in UMTS mobile network. It describes in brief the RLC protocol, its functions, properties, parameters, data structure and functional modes. In detail this study reports the acknowledged mode SDU discard procedure and its effect on the protocol performance. For the purpose of monitoring behavior of two RLC entities and performance evaluation of the RLC protocol with different values of RLC parameters a simulation program was developed. Graphic simulation outputs reporting the effect on performance are attached in the paper.

The UMTS 3G system (3 rd generation cellular system) is designed to offer a packet switched mode for data transfers in parallel to a circuit switched mode. This feature was planned since the beginning of 3G studies, contrary to 2G ones (such as the GSM system). To provide reliable data transfers, protocols implementing ARQ (Automatic Repeat reQuest) techniques are needed. In UMTS, up to three A...

In this paper, the combination of packet level Space-Time Block Coding (STBC) with an adaptive Hybrid Automatic Repeat reQuest (HARQ) algorithm for efficient and reliable multicast transmission in UMTS networks is proposed. The aim of this paper is to provide a cross-layer design of packet-data transmissions in Multiple-Input Multiple-Output (MIMO) systems employing orthogonal STBC over Rayleig...
متن کاملRLC buffer occupancy when using a TCP connection over UMTS
This paper analyzes a TCP connection over UMTS radio access bearer in RLC acknowledged mode. The stacking of RLC and TCP protocols is highly beneficial for the global system behavior. Protocol mechanisms used by RLC are well adapted to wireless constraints and the ARQ function implemented by RLC hides the wireless channel unreliability to TCP. However, RLC protocol parameters have to be careful...
متن کاملSimulation Analysis of Rlc Timers in Umts Systems
Radio Link Control (RLC) is the layer two protocol used in 3G UMTS cellular systems for flow control and error recovery. Due to the complexity of the protocol and the multitude of parameter configurations available, it is extremely difficult to model RLC analytically. Therefore we present a simulation model to study RLC performance in UMTS systems. We focus on the impacts of the poll prohibit t...
