Methods and apparatus for intelligent power reduction in communications systems
Methods and systems are provided for power control in communications devices. Bonding of channels in communication devices may be dynamically adjusted, such as responsive to requests for bandwidth adjustment. For example, bonded channel configurations may be adjusted based on power, such as to single channel configurations (or to channel configurations with small number of channels, such as relative to current configurations) for low power operations. Components (or functions thereof) used in conjunction with receiving and/or processing bonded channels may be dynamically adjusted. Such dynamic adjustments may be performed, for example, such as to maintain required synchronization and system information to facilitate rapid data transfer resumption upon demand.
