full_form: Receive Total Wideband Power
context: Evolved HSPA architecture - stand-alone deployment scenario - is a solution for a flat radio access architecture of UTRAN network. In this architecture the RNC functions are in the NodeB, which in the present document is named as evolved HSPA NodeB. Evolved HSPA system enables to use 3GPP Release 5 and later Releases of air interface with no modifications for HSPA traffic. The intended use scenario for HSPA capable terminals is to utilise HSPA both in uplink (E-DCH) and in downlink (HS-DSCH). Figure7.1.4-1 illustrates evolved HSPA architecture. Figure 7.1.4-1:Evolved High Speed Packet Access architecture The evolved HSPA NodeB has Iu-PS interface towards packet switched CN. Iu-PS user plane is terminated either in SGSN or in case of one tunnel approach (Rel-7) in GGSN. Evolved stand-alone HSPA is designed with full mobility support, including handovers within the system. Intra-system handover in evolved HSPA is executed between cells, which belong to different evolved HSPA NodeBs
description: Receive Total Wideband Power (RTWP) is a measurement used to control interference between cells. It measures the total power received by a cell from all sources, including neighboring cells. RTWP targets can be set for each cell or even for specific portions of a cell to manage interference and ensure optimal network performance.
explanation: The context describes RTWP as a measurement value that varies across different areas within a cell due to overlap with neighboring cells. It highlights the need to control RTWP in each area separately to manage interference, indicating that RTWP is a metric used for assessing and controlling signal strength and interference.
