Abstract :
A generalized and autonomous discontinuous reception (DRX) scheme, which is applicable to both Third-Generation Partnership Project (3GPP) and IEEE 802.16e standards, is analyzed by two-level Markov chain modeling, along with the European Telecommunications Standards Institute (ETSI) packet traffic model. Numerical analysis showed that this scheme is capable of autonomously adjusting the DRX cycle to keep up with changing user equipment activity level with no signaling overhead increase, thus producing a better tuned DRX operation. Quantitative comparison with the power-saving schemes of 3GPP and 802.16e standards demonstrated that the autonomous DRX scheme is advantageous over these power-saving schemes.
