Abstract
A muticarrier transceiver is provided with a sleep mode in which it idles with reduced power consumption when it is not needed to transmit or receive data. The full transmission and reception capabilities of the transceiver are quickly restored when needed, without requiring the full (and time-consuming) initialization commonly needed to restore such transceivers to operation after inactivity.
Claims31
A method of operating a multicarrier transceiver having a sleep mode capability, the method comprising:
- placing at least one component of a first multicarrier transceiver in a sleep mode;
- storing at least one parameter representative of a full power mode of said at least one component of said first multicarrier transceiver;
- maintaining synchronization between said first multicarrier transceiver and a second multicarrier transceiver using a synchronization signal while said at least one component of said first multicarrier transceiver is in said sleep mode;
- recovering said at least one stored parameter in response to a signal to awaken from the sleep mode;
- and
- restoring said at least one component of said first multicarrier transceiver from the sleep mode to the full power mode without needing to reinitialize said first multicarrier transceiver by using said at least one recovered parameter.
3 more elements
A multicarrier transceiver having a sleep mode capability, comprising:
- memory that stores at least one parameter representative of an operating mode of said multicarrier transceiver;
- a controller that places at least one component of said multicarrier transceiver in a sleep mode responsive to a sleep mode signal and restores said at least one component of said multicarrier transceiver to the operating mode in response to an awaken signal, the restoration to the operating mode occurring without needing to reinitialize said multicarrier transciever by recovering said at least one stored parameter from the memory;
- and
- a synchronizer module that uses a synchronization signal to maintain synchronization between said multicarrier transceiver and a second multicarrier transceiver while said at least one component of said multicarrier transceiver is in the sleep mode.
