Adaptive control of RF low power modes in a multi-rate wireless system using MCS value

A wireless communication device, comprising:

• a receiver configured to receive control information for incoming data in a transmission frame while in a first power mode of the device, the control information including a modulation and coding scheme (MCS) value;
• and
• a power controller configured to:
• adjust for phase error before switching to a second power mode to mitigate phase error caused by switching, wherein the adjusting comprises implementing an MCS rate for a transition point between the first power mode and the second power mode, the implemented MCS rate being lower than an MCS rate associated with the second power mode and having error vector magnitude (EVM) constraints that mitigate phase error caused by switching;
• and
• adaptively switch to the second power mode of the device during the transmission frame, wherein the switching is based at least in part on the received MCS value and a bandwidth mode for reception.

An apparatus for adaptive power control for a wireless communication device, comprising:

• means for receiving control information for incoming data in a transmission frame while in a first power mode of the device, the control information including a modulation and coding scheme (MCS) value;

• and
• means for adaptively switching to the second power mode of the device during the transmission frame, wherein the switching is based at least in part on the received MCS value and a bandwidth mode for reception.
