Abstract: A method permits a UE receiver to detect and report to the network a scrambling code collision (i.e., two neighbor cells transmitting with the same scrambling code while timing is aligned). The UE receiver decodes the PCCPCH's physical channel with all the associated broadcast information while a scrambling code collision at the UE is present. The UE reports SFN-SFN information to the network, to insure the UE mobility and then prepare the handover to a new detected cell. This process and a respective apparatus are usable in the presence of MIMO and further improve the detection of the scrambling code collision in the presence of MIMO.

Abstract: A method of controlling a frequency selection of a PLL used in cooperation with a device of a wireless communication network, such as a Universal Mobile Telecommunication System (UMTS) network, the method comprising:—receiving a first set of signal measurements;—comparing the first set of signal measurements with a first threshold and, selectively switching the PLL frequency from a first value to a second value as a result of the comparison of the first set of signal measurements with the first threshold;—further receiving a second set of signal measurements; and,—comparing the second set of signal measurements with a second threshold, different from the first threshold, and selectively switching the PLL frequency from the second value to the first value as a result of the comparison of the second set of signal measurements with the second threshold.

Abstract: A method permitting a UE receiver to detect and then report to the network a scrambling code collision i.e. 2 neighbor cells are transmitting with the same scrambling code while timing is aligned. Furthermore the UE receiver is configured to decode code the PCCPCH's physical channel with all the associated broadcast information in presence of a scrambling code collision at the UE. It also allows the UE to report SFN-SFN information to the network, which is necessary to insure the UE mobility and then prepare the handover to a new detected cell. The process and apparatus described is applicable in the presence of MIMO and further improves the detection of the scrambling code collision in the presence of MIMO.
