Abstract

This paper presents various dynamic timeslot-code assignment (TCA) strategies, using heuristic rules or online measured information, suitable to support real-time multimedia services in UTRA-TDD. In the measurement-aided TCA scheme employing minimum instantaneous power (MIP) criterion, the base station assigns resources to an active burst in the timeslot where the corresponding mobile terminal will transmit minimum power to meet a target signal to interference and noise ratio (SINR). A self-corrective (SC) strategy used with the MIP scheme is introduced to adapt to interference variations during burst transmission. The satisfied user criterion is used as a metric to assess the system capacity. Simulations using OPNET for both speech and streaming video services are presented. Simulation results show that the SC-MIP outperforms the other simple TCA schemes.
