Method of UE RSRQ measurement precaution for interference coordination
Abstract:
A method of UE RSRQ measurement precaution for interference coordination is provided. The UE receives radio signals of a neighbor cell under measurement. The neighbor cell applies a TDM silencing pattern for inter-cell interference coordination (TDM ICIC). The UE determines a measurement pattern that includes multiple subframes. The UE performs RSRQ measurements of the cell over multiple subframes and obtains multiple RSRQ measurement samples. The UE derives RSRQ measurement result by estimating the multiple RSRQ samples and applying a weighted average. RSRQ samples estimated to be more applicable are taken into account to more extent (e.g., applied with more weight), and/or RSRQ samples estimated to be less applicable are taken into account to less extent (e.g., applied with less weight, or discarded with zero weight). With UE precaution, a more predictable RSRQ measurement result is produced.
