METHOD AND APPARATUS FOR ADVOIDING IN-DEVICE COEXISTENCE INTERFERENCE IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for coexistence interference avoidance in a user equipment (UE) having a first radio with an LTE/LTE-Advanced radio technology and a second radio based on another radio technology includes initiating a time division multiplexing (TDM) solution in the UE on a serving cell between the first and second radios, the TDM solution defining scheduling periods and unscheduled periods. In one embodiment the UE increments the PREAMBLE_TRANSMISSION_COUNTER by 1 for each random access preamble transmission reattempt during the random access procedure, and the UE considers an unscheduled period of the TDM solution when determining the next available Physical Random Access Channel (PRACH) subframe for preamble transmission.
