Method and apparatus for reducing power consumption of simultaneous receivers in a wireless communications device

摘要

A method for power management for use in system selection by simultaneous receivers taking into account power use during an idle state. A power penalty is determined for each of a plurality of wireless technology systems available to a receiver when conducting page monitoring sequences. Combined power penalties are determined for various combinations of wireless technology systems. Wireless technology systems are selected in a preferred combination having a least combined power penalty for monitoring pages during an idle mode.

主权项

1. An apparatus, comprising:
a wireless receiver configured for receiving signals from a plurality of wireless technology systems; a system determination module for determining wireless technology systems for each type of wireless technology that are available to said wireless receiver, wherein said system determination module is configured to determine one or more combinations of wireless technology systems selected from said plurality of wireless technology systems; a power penalty monitor for determining a power penalty for each of said plurality of wireless technology systems during a page monitoring wake-up sequence; a selection module for determining one or more combined power penalties for combinations of wireless technology systems selected from said plurality of wireless technology systems, wherein a preferred combination comprising selected wireless technology systems has the least combined power penalty, wherein a combined power penalty for a corresponding combination as determined by said selection module comprises a combined power consumption for page monitoring wake-up sequences for each wireless technology system in said corresponding combination, and wherein said combined power consumption is based on a page monitoring cycle and an average power use during said page monitoring cycle over a period.
