“…3 shows a model for video streaming traffic [10] as an example of RT-VR service recommended by Power Saving Class of type II. Notice that sleep window is always same to W 1 regardless of the depth of sleep mode as is shown in (2). Thus, the power saving effect totally depends on the choice of W 1 .…”

“…The conventional sleep window scheme such as that of IEEE802.11 has the fixed length of sleep window. Motegi et al [2] proposed a new method of which sleep window has different length according to the depth of sleep state. They showed that significant power savings can be achieved, especially in case of non-real-time traffic, by adjusting the length of sleep window based on the depth of sleep state.…”

In this paper, we propose an adaptive initial-sleep window scheme applicable to both Power Saving Class of type I and type II in IEEE802.16e. Based on the estimated inter-arrival time of packet burst, the presented scheme adaptively updates the length of the initial-sleep window in order to maximize power-saving effect while trying to minimize packet buffering delay. The computer simulations are carried out for web browsing and streaming video, the most typical BE service in Power Saving Class of Type I and RT-VR service in Power Saving Class of type II, respectively. The simulations show that the proposed scheme improves the power-saving effect in terms of the awake rate and the normalized active time while suppressing the increase in the mean packet delay.

Broadband CDMA packet access is one of the most promising air interfaces for future 4G mobile communication systems. In this study, a novel reservation-based access protocol with prioritized resource allocation (PRA) is proposed as a reverse channel MAC protocol, which enables various rate realtime communications on such a system. In this protocol, a lowrate Temporal Dedicated Control CHannel (TDCCH) is momentarily assigned between a base station (BS) and mobile station (MS). A TDCCH is used to transmit not only access control signals including a reservation signal, but also transmission control signals such as Transmission Power Control (TPC) commands. This protocol prevents a packet-by-packet setup delay and provides contention-free packet reservation so long as a TDCCH is established. The duration of the TDCCH can be controlled according to the Quality of Service (QoS) requirement. PRA is based on such a reservation scheme, and two different resource allocation areas are defined in time slots that correspond to real-time and best-effort classes. The realtime packets have a wider allocation area so that they can acquire radio resources prior to best-effort packets. Thus, resources are assigned to real-time packets first, and the remaining resources can be used for best-effort packet transmission. By combining admission control and tlow-control with PRA, real-time packet communication can be achieved in the reverse channel. The performance of the proposed protocol is evaluated by computer simulation and through an experimental system.

Abstract-In general, a power amplifier utilizes battery energy more efficiently with a higher transmission power. For a given message, a given bandwidth constraint and a given performance constraint, different allocations of the bandwidth among source coding, channel coding and modulation result in different amounts of battery usage. We propose a method to optimize the bandwidth allocation and minimize the battery consumption due to transmission. Our results show that with the optimal allocation, significant reduction in battery consumption can be achieved without sacrificing the system performance.
