Power headroom reporting for in-device coexistence interference avoidance

摘要

The invention relates methods for maximum output level reporting by a mobile terminal in a mobile communication system. The invention is also providing apparatus for performing these methods, and computer readable media the instructions of which cause the apparatus to perform the methods described herein. In order to allow for maximum output level reporting, a power management related power backoff value is first calculated for one radio technology by referring to a reception quality level set for communication via the other radio technology; thereafter a lower and upper bounds of a maximum output power level is calculated, then the maximum output power level ( P CMAX ) for communication is set within the determined lower and upper bounds and finally the set maximum output power level is reported to a base station wherein the lower bound (P CMAX_L ) may be calculated using MPR = 0 dB , A - MPR = 0 dB , and optionally ” T c = 0 dB.
