Abstract
The invention claims a power control method for reducing device in a coexistence interference. a wireless communication device (such as user device) is configured with the second Wireless Fidelity/Bluetooth/global navigation satellite system radio module a first Long Term Evolution radio module and cooperation. In a first embodiment a long term evolution radio module adjusts its power or power parameters locally without informing the serving evolved Node-B. In a second embodiment a long term evolution radio module adjusts its power parameters and implicit informing an evolved Node B by current power headroom report. In a third embodiment a long term evolution radio module changes the power or the power level and user device function a new radio resource control information or media access control control unit informing an evolved Node B.
A power control method to mitigate in-device coexistence (IDC) interference is provided. A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference the UE applies power control method to mitigate the interference. In a first embodiment the LTE radio module adjusts its power parameters locally without informing the serving eNB. In a second embodiment the LTE radio module adjusts its power parameters and implicit informs the eNB through existing PHR reporting. In a third embodiment the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead or have higher impact on throughput.
