Embodiment approach

[0038] For an implementation manner, providing the modified link quality indicator to the base station includes: providing a modified head room (head room) indication to the base station. The headroom can generally be defined as how much extra transmit power the wireless device can use. That is, the headroom represents the power deviation between the maximum available transmit power of the wireless device and the current transmit power of the wireless device. This can also be defined as the difference between the nominal maximum transmit power and the estimated transmit power.

[0039] The logic control can be included in the controller of the wireless device. Additionally, or alternatively, logic control may reside within either the first technology modem or the second technology modem. For specific implementations, logic control is not placed within the host controller of the wireless device. For one embodiment, the power level of the first technology is communicated dire...

Abstract

The present invention discloses methods and apparatus for power and handover management in a variety of wireless technology communication devices. A method includes a wireless device communicating using a first technology and detecting availability of a second technology. Logic control of the wireless device receives an indication of the power level of the communication signal of the first technology and determines an acceptable power level of the communication signal of the second technology based on the indication of the power level. The logic control determines a requested power level of the communication signal of the second technology based on the request from the base station. If the requested power level is greater than the acceptable power level, the logic controls provide a modified link quality indication to the base station. The wireless device communicates with the base station using the second technique at an acceptable power level.

Description

technical field [0001] The described embodiments relate generally to wireless communications. More specifically, the described embodiments relate to methods and apparatus for power and handover management in a multi-wireless technology communication device. Background technique [0002] Wireless communication technology is rapidly evolving and being widely used. In some cases, wireless connectivity to multiple (eg, 3G, WiMAX, CDMA2000, EVDO-RevA, HSPA, LTE, and GSM) wireless networks may be available at a given location. However, at a given location, one type of network may provide better wireless connectivity as determined by better Quality of Service (QoS) or Signal-to-Noise Ratio (SNR). Additionally, one type of network may provide support for a better type of data communication. [0003] Typically, a user device of a wireless network user can only communicate with one type of wireless network at a time. Thus, the user cannot take advantage of better connections provi...
