Abstract

The main focus of this letter is on the non-real-time service where the so-called best effort type of resource management is applicable. Given an amount of data packets to each user, the problem of minimizing the time span to send all the packets is investigated. In particular, the problem is elaborated in the CDMA contest. With Bellman´s (1957) principle of optimality, we derive an optimal scheduling, in which users transmit data through a hybrid of CDMA and TDMA. Numerical results show that by having optimal scheduling, we can significantly reduce the transmission time span, and thereby increase the radio network capacity.
