PROBLEM TO BE SOLVED: To provide a base station that supports a transmit standby mode and an active mode.SOLUTION: Transmit standby mode is a low power/low interference level of operation as compared to active mode. In the transmit standby mode, 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 the transmit standby mode, the base station 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. |
