Abstract:
1. An apparatus for coordinating radio activities in different radio access technologies (RATs), comprising: a first RAT module, performing a first channel activity, related to a first RAT, for transmitting or receiving information to or from a first cellular network by using an antenna, and requesting that a measurement activity, related to the first RAT, is to be performed for measuring signal power of a serving cell and/or at least one neighbor cell in the first cellular network by using the antenna; a second RAT module, requesting that a second channel activity, related to a second RAT, is to be performed for transmitting or receiving information to or from a second cellular network by using the antenna; and an arbiter, scheduling performance of the measurement activity between the first and second channel activities, wherein the scheduling comprising: calculating a time offset between the first and second channel activities based on timing parameters of the channel activities received from the first and second RAT modules; scheduling at least a portion of the measurement activity with duration that is less than the time offset; scheduling the remaining, if any, of the measurement activity after a forth coming channel activity is completed; wherein the first channel activity has to be performed at a specific time synchronized with the first cellular network and the second channel activity has to be performed at a specific time synchronized with the second cellular network.
