INTER-MODULATION DISTORTION REDUCTION IN MULTI-MODE WIRELESS COMMUNICATION TERMINAL

摘要

A multimode wireless communication terminal that communicates using a first radio access technology (RAT) and a second RAT determines whether the first and second RATs are in an active state, and modifies a maximum transmit power limit of the first RAT based on a voice codec rate of a voice transmission on the second RAT when the first RAT and the second RAT are in the active state concurrently, wherein the second RAT is conducting the voice transmission in the active state. In an alternative embodiment, the limit is modified based on a transmit power status of the second RAT or on a transmission type of the first RAT.

主权项

1. A method in a multimode wireless communication mobile terminal that communicates using a first radio access technology (RAT) and a second RAT, the method comprising:
determining whether the multimode wireless communication mobile terminal has been assigned a first identifier for communicating with the first RAT and a second identifier for communicating with the second RAT; receiving an operational maximum power at which the multimode wireless communication mobile terminal can transmit on the first RAT; reducing the operational maximum power of the first RAT to a modified maximum transmit power based on a codec rate of a voice transmission on the second RAT when the multimode wireless communication mobile terminal has been assigned the first identifier for communicating with the first RAT and the second identifier for communicating with the second RAT; and transmitting on the first RAT at a transmit power level based on the modified maximum transmit power when the voice transmission is conducted by the second RAT.
