Within a communication system that includes multiple communication channels, a low-power mode of operation and a higher-power mode of operation are provided. Each channel is allocated to one of several groups, based on criteria such as whether power is allocated to that channel in low power mode, and whether power was allocated to that channel in a previous high power mode. Initial power levels for each channel for each mode are approximated using an interpolation rule known to both the receive and the transmitter. The system switches between modes according to a PMD pre-defined schedule. When a new power mode begins, the receiver measures signal power received on each channel and then transmits corrective information sufficient to allow adaptation of power levels to achieve PMD pre-defined levels of received power.
A method for communicating within a communication system that includes a plurality of communication channels operable to communicate bits of information in a high power mode of operation and operable to communicate bits of information in a low power mode of operation, the method comprising, for the low power mode of operation, selectively allocating power to a channel in the plurality of communication channels based on channel use during the high power mode of operation of the respective channel.
A non-transitory computer readable medium storing software that, when executed on one or more processors in a communication system that includes a plurality of communication channels operable to communicate bits of information in a high power mode of operation and operable to communicate bits of information in a low power mode of operation, causes, for the low power mode of operation, selectively allocating power to a channel in the plurality of communication channels based on channel use during the high power mode of operation of the respective channel.
An apparatus for use in a communications system having a plurality of communication channels operable to communicate bits of information in a high power mode of operation and operable to communicate bits of information in a low power mode of operation, the apparatus comprising circuitry configured, for the low power mode of operation, to selectively allocate power to a channel in the plurality of communication channels based on channel use during the high power mode of operation of the respective channel.
