Patent ID: 8139540

Claim:
An apparatus comprising: a monitoring apparatus of a wireless communication terminal operative for receiving first mode signals in a first mode and second mode signals in a second mode, wherein the monitoring apparatus is arranged to operate in a slot synchronisation stage on a primary synchronisation channel, the received first and second mode signals comprising frames of different lengths and different numbers of slots in each frame, and successive slots of a first frame of the received second mode signals includes signal data that is repeated in subsequent frames of the received second mode signals, said monitoring apparatus including; a monitoring arrangement operative, while the wireless communication terminal is communicating in said first mode, for monitoring signal data of the first frame and at least two consecutive frames of the received second mode signals consecutive with the first frame and processing said signal data of the first frame, the monitoring apparatus further operative for inhibiting processing of said signal data of the first frame received during a first slot of the first frame if the first slot is simultaneous with a transmission in said first mode, the monitoring arrangement including: a frame detector configured to count a number of the subsequent frames of the received second mode signals; and a delay element coupled to the frame detector, the delay element configured to delay the processing of said signal data until the frame detector detects reception of two of said subsequent frames of the received second mode signals, and to enable the monitoring arrangement to extract a second slot of a second frame of said received second mode signals and to enable the monitoring arrangement to process the signal data extracted from the second slot of the second frame of said received second mode signals in response to the frame detector detecting reception of two of said subsequent frames of the received second mode signals, the second slot corresponding to the first slot inhibited during the first frame, the second frame is subsequent the first frame, and is one of said at least two consecutive frames, and the second slot is not simultaneous with the transmission in said first mode.
