Method and apparatus for use as a hollow in wireless networks

A method (900) to use a gap measurement, comprising: communicating (902) wirelessly in a source carrier frequency (206), receiving (904) an allocation of a hollow measuring (202) at the source frequency carrier (206) to independently determine to remain tuned to the source carrier (206) frequency duranteal least part of the gap measurement (202); determining whether to perform a transmission physical random access channel, PRACH, which elhueco collides with measuring (202) based on a potential subsequent transmissions related alProcedimiento random access measuring the gap (202) collision; ysintonizar selectively between the source carrier (206) frequency and a target frequency deporting (210) during the measurement gap (202) in accordance with the independent determination.
