Benefits of technology

The present invention improves wireless communication systems by effectively utilizing multiple carrier frequencies for wider coverage without requiring frequent reconfiguration or interference from nearby cells. This results in improved reliability and reduced delays during data transfer.

Problems solved by technology

This patent describes two methods for improving the performance of mobile networks: frequency division multiple access (FDMA) and code division multiple access (CDMA). These techniques allow users to share their available spectrum while still transmitting signals efficiently. However, these techniques may also cause interference issues when accessing the same frequencies simultaneover. To address this issue, certain standards bodies propose specific procedures called Time Division Multiplexing Access Interval (TDMI) Measurement Report (TMREQ) protocols to monitor the signal quality during connection establishment.

Abstract

The present invention relates to a method and apparatus for determining radio link failure between the UE and the eNB in a wireless communication system. Particularly, the present invention provides a method and apparatus for determining radio link failure efficiently in such a way that the UE measures the radio link quality of the anchor carrier, the radio link qualities of the aggregated carriers, and the radio link quality of neighbor cells in order, and determines whether the radio link quality fulfills a predetermined condition.
