摘要： The present invention relates to a method to be performed in the context of multipath detection. The method comprises ascertaining a channel-condition indicator indicative of a current channel condition on a control channel used for receiving a pilot-symbol signal, setting a number of pilot symbols to be used in performing a multipath-detection in dependence on the ascertained channel-condition indicator; ascertaining a correlation measure between a section of the pilot-symbol signal comprising the set number of pilot-symbols and an expected pilot-symbol signal comprising the set number of pilot symbols; and performing multipath detection using the ascertained correlation measure. Setting the number of pilot symbols to be used by a multipath-detector unit in performing the multipath-detection in dependence on the ascertained channel-condition indicator allows saving under certain channel conditions, e.g., weak signal fading.

摘要： 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 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.

摘要： Multiple-input multiple-output (MIMO) with multiple power amplifiers (404, 406) and antennas (408, 410) in a mobile transmitter, such as a user equipment for a cellular telephone communication system, has such great impacts on the transmitter's battery life, form factor, and complexity that it should not be used unless its benefits clearly outweigh its costs. Methods and apparatus of the invention enable to obtain the benefits of MIMO by beam-forming and antenna-switching without incurring the drawbacks of increased current consumption due to multiple power amplifiers.
