    • Wireless terminal for use with a multi-mode base station that supports a transmit standby mode and an active mode is described. Transmit standby mode of base station operation is a low power/low interference level of operation as compared to active mode. In transmit standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In transmit standby mode, the base station has no active state registered wireless terminals being serviced but may have some sleep state registered wireless terminals being serviced. Mode transitions from active to transmit standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmit standby to active may be in response to: scheduling information, access signals, wake-up signals from the wireless terminal, hand-off signals, etc.
    • 描述了与支持发送待机模式和活动模式的多模式基站一起使用的无线终端。 与主动模式相比,基站操作的发送待机模式是低功耗/低干扰电平。 在发送待机模式中,诸如导频音调信令的至少一些同步信令相对于活动模式降低功率电平和/或速率。 在发送待机模式中,基站没有被激活状态登记的无线终端被服务,但是可能有一些睡眠状态登记的无线终端被维护。 模式从有效切换到发送备用的转换可以是:检测到的不活动时段,调度信息,基站模式改变信号和/或检测到的无线终端状态转换。 从发射待机到激活的模式转换可以响应于:调度信息,接入信号,来自无线终端的唤醒信号,切换信号等。
