DYNAMIC PRIMARY SCRAMBLING CODE DISAMBIGUATION
First Claim
1. A method comprising:
- receiving a measurement report from user equipment (UE) including a primary scrambling code (PSC) indicative of a target cell;
creating a radio link on each of a plurality of cells, including the target cell, that are associated with the PSC;
performing a synchronization procedure to add the created radio links to the UE'"'"'s active set; and
receiving a radio link restore indication for one of the created radio links associated with the target cell.

Abstract
Systems and methods are provided for resolving Primary Scrambling Code (PSC) ambiguity. A radio link having the same PSC as that reported by user equipment (UE) may be created on some or all internal cells which are chosen based on radio frequency (RF) proximity to a serving cell of the UE or one or more iterations of a PSC resolution set selection process. If the UE is reporting the PSC of one of these cells, the UE and a Node Bs will be able to successfully complete a synchronization procedure to add one of the radio links to the UE'"'"'s active set, while any remaining created radio links can be deleted. After a certain number of successful radio link additions, the combination of the PSC and active set may be considered to be resolved, therefore, negating a need to resolve the PSC in subsequent soft handover requests.

10. An apparatus comprising:
-
a processor; and a memory including computer program code, the memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following; receive a measurement report from user equipment (UE) including a primary scrambling code (PSC) indicative of a target cell; create a radio link on each of a plurality of cells, including the target cell, that are associated with the PSC; perform a synchronization procedure to add the created radio links to the UE'"'"'s active set; and receive a radio link restore indication for one of the created radio links associated with the target cell. - View Dependent Claims (11, 12, 13, 14)
