Reducing interference in inter-frequency measurement
First Claim
1. A method for defining measurement gaps in a wireless telecommunications system comprising at least one base station and several wireless terminals, the method comprising the steps of:
- defining for the wireless terminals in the telecommunications system measurement patterns which define locations of gaps used for measurements in a time-slot frame, sending the measurement patterns to corresponding wireless terminals through the base station, wherein various terminal-specific delays are defined for the measurement patterns of the wireless terminals so that the gaps of different terminals are in substantially different locations in the time-slot frame.

Abstract
A method for defining measurement gaps in a wireless telecommunications system comprising at least one base station and several wireless terminals. The telecommunications system comprises means for defining measurement patterns for terminals, which measurement patterns set locations of gaps used for measurements in a time-slot frame, and the base station comprises a transmitter for transmitting the measurement patterns to the corresponding terminals. In the method, measurement patterns are defined for the terminals, setting the locations of the gaps used for measurements in a time-slot frame, the measurement patterns are transmitted through the base station to the corresponding terminals and various delays are defined for the measurement patterns of the terminals so that the gaps of different terminals are in substantially different locations in the time-slot frame.
