P-CPICH Scrambling Code Collision Detection

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 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.

1. A method for a PCCPCH decoder to detect cells with colliding scrambling codes comprising the steps of:
Monitoring the scrambling code of a cell, Synchronizing with a neighbor cell, Detecting a scrambling code collision and flagging it,Wherein, the method further comprises the step of checking the PCCPCH decoder to determine if correct broadcast information has been applied on the monitored cell.
