    摘要： A wireless communications power saving method and apparatus is provided. The method includes establishing a circular buffer configured to maintain a number of most recently encountered frame delay times and waiting a frame delay time after receiving a further frame before the station enters a power save state. Frame delay time is a period equal to a largest most recently encountered frame delay period in the circular buffer. The method further determines, at a station, a dormancy time based on a number of data frames received since the station transitioned from an inactive mode to an active mode, a packet transmission rate, and a data frame time interval representing time between data frames received at the station, and causes the station to switch to a further inactive mode if a next packet is not received within the dormancy time after receipt of a previous packet.

    摘要： Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

    摘要： A wireless communications power saving method and apparatus is provided. The method includes, when no reverse link traffic exists and no forward link traffic has been received for a predetermined amount of time, establishing, at a terminal, a reverse link transmission pilot signal duty cycle, and boosting overhead channel signal transmission power during ON slots and gating overhead channel and pilot signal transmission power during OFF slots. The design further includes estimating, at the terminal, an available data transmission rate, determining an actual data transmission rate, setting a terminal transmission duty cycle for a next period based on the estimated available data transmission rate, the actual data transmission rate, and a margin of error, and transmitting data from the terminal according to the terminal transmission duty cycle.
