context: If a secondary scrambling code is activated, then the entire OVSF code space on the SSC is available. So HSDPA users can be scheduled on a part of the Primary Scrambling Code (PSC) space originally assigned and the entire SSC code space. The introduction of a SSC allows full reuse of the OVSF code space and can be achieved in the following ways: 1) Introduction of SSC on Same Antenna(s) as PSC: The use of a SSC on the same antenna(s) as a Primary Scrambling Code (PSC) may lead to excessive interference to UEs on both the PSC and the SSC since the instantaneous channel gains on the desired signal and interference components are perfectly correlated. Multi-user detection techniques can be applied to cancel out the resulting interference, albeit at the cost of additional UE complexity. 2) Introduction of Antenna Specific SSC: This allows cross antenna interference rejection through scheduling, in a manner similar to that in 6.4.1.1above, in addition to the interference rejection benefits
description: Network Assisted Cell Change (NACC) is a procedure used in mobile networks to assist in the process of changing cells, particularly in GSM systems. The NACC related data IE provides necessary information for this process, facilitating smooth handovers and ensuring continuous service availability.
explanation: The context mentions 'NACC Related Data' being provided for an indicated GSM cell, indicating that NACC is a specific process or mechanism used within the network to manage cell changes. This classification as a procedure is based on its role in assisting with cell change operations.
