Abstract

A UE, in an idle mode, receives pilot signals and synchronization signals from a serving cell and neighbor cells comprising neighbor cells listed and/or unlisted in a neighboring cell list. The UE validates each of the serving cell, the listed neighbor cells and the unlisted neighbor cells from the received signals. The UE performs cell measurement on the listed cells as well as the unlisted cells for multipath profiles and associated power levels. In instances where number of attempts of the cell measurements on the unlisted cells exceeds a threshold value, the UE may validate presence of the unlisted cells. The best available cell is selected from the listed cells and the unlisted for the UE to camp on. I/Q samples of the received signals are stored while measuring or monitoring the cells. The stored I/Q samples may be utilized to carry out baseband procedures through offline processing.
