Claim Text:
1. A method of operating a user equipment (UE) in a cellular telecommunications system, the method comprising: receiving a signal from a neighboring cell, wherein the signal comprises a plurality of slots of which some of the plurality of slots are downlink slots and some of the plurality of slots are uplink slots, and wherein a configuration of the downlink and uplink slots is unknown; detecting a characteristic of the received signal; using the detected characteristic as an indicator in a blind detection process that relies on characteristic differences between uplink and downlink slots to identify the configuration of the downlink and uplink slots in the received signal; and using the identified configuration of the downlink and uplink slots to obtain known pilot signals from one or more downlink slots of the received signal and using the known pilot signals to obtain a signal power measurement of the received signal, wherein: the detected characteristic is a detected information content of resource elements of the received signal known to be reference symbol resource elements in a downlink subframe, wherein each resource element is defined by subcarrier frequency and time of occurrence; and the blind detection process comprises correlating the detected information content with information content of one or more known reference symbols.
