A simplified layered scheduling scheme is presented, which is based on utility-based scheduling, such as Max-Delay- Utility (MDU) scheduling in this paper. In this scheme, the scheduling is divided into two steps-- macro and micro scheduling. In macro step, the utility functions of traffics are defined, according to which the scheduling order of various services is determined. Then in micro step,...
The TDD-CDMA system with unbalanced slot allocation between uplink (UL) and downlink (DL) is useful for the traffic asymmetry, but the unbalanced slot will lead to cross-slot interference. This paper proposes a novel admission control algorithm for TDD-CDMA in order to decrease the cross-slot interference. The novel admission control deal with each user in different slots: for user with high transmission...
In future wireless communications, there will be a mixture of different traffic classes, which have their own load and quality-of-service (QoS) requirements. In this paper, a traffic load and QoS-oriented packet scheduling (TLQS) is proposed for WCDMA communications, which consider the bit error rate (BER), packet loss, delay and traffic load requirements. The BER requirement can be guaranteed by...
