full_form: Orthogonal Variable Spreading Factor (codes)
context: CU detects PCI conflict and indicates to OAM directly. OAM assigns a new PCI. When the CU detects the PCI conflict between NR cells within a DU or between neighbouring gNBs, it sends the PCI conflict to OAM directly. And the OAM will allocate a new PCI value for the cell having PCI conflict and configure it to the DU. Case 2: Distributed PCI selection, OAM configures a list of PCIs to each NR cell In this case, the OAM signals a list of PCIs for each cell to the DU, and DU selects one from the list for each NR cell. The DU sends the selected PCI of each serving cell to the CU during F1 setup. - Option 2a: CU detects PCI conflict and indicates to DU. DU reassigns a new PCI. When the CU detects the PCI conflict, it sends the PCI conflict indication to the DU. In addition, the CU sends the PCIs of cells neighbouring to the cell subject to PCI update to the DU, or allowed PCIs, or non-allowed PCIs to the DU. The DU may restrict the PCI list considering the information suggested by CU.
description: The Orthogonal Variable Spreading Factor (OVSF) codes are parameters used in the transmission algorithms of a Node-B to manage the allocation of spreading factors for different streams during one scheduling period. The goal is to optimize the reuse of OVSF codes so that each code is used as few times as possible, thereby minimizing interference and maximizing efficiency.
explanation: The context describes OVSF codes as parameters within transmission algorithms, responsible for managing spreading factors and optimizing code reuse. This clearly classifies them as parameters used to configure and control the system.
