full_form: UE Positioning
context: The following RNC complexity aspects are considered in this subsection : throughput, buffering / scheduling and interfaces. Throughput As the cell throughput at 7.68Mcps is approximately 10% greater than at 3.84Mcps (section 5.3.2.5.4), RNCs will have to support a higher mean data rate at the higher chip rate. Buffering Typically 30-40% more packet users can be supported at 7.68Mcps than at 3.84Mcps. The buffering requirements for USCH, HS-DSCH and DSCH data in the RNC will thus be proportionately greater at the higher chip rate. RRM Twice as many cells are supported at 3.84Mcps than at 7.68Mcps, thus twice as many RRM instances are required at 3.84Mcps than at 7.68Mcps. Interfaces The higher mean data rate that 7.68Mcps systems support leads to a requirement for slightly higher interface speeds on the Iub, Iur and IuPS / IuCS interfaces. These interfaces need to be approximately 10% faster at 7.68Mcps compared to 3.84Mcps.
description: The UE Positioning (UP) protocol, specifically referred to as Iu UP in this context, operates in the User plane of the Radio Network layer over the Iu interface. It is responsible for conveying user data associated with Radio Access Bearers (RABs). Each RAB has one associated Iu UP protocol instance, and multiple instances can exist if several RABs are established towards a single UE.
explanation: The context describes how Iu UP manages data transmission over the Iu interface, specifically for user data related to Radio Access Bearers. This function of defining rules and structure for data transfer aligns with the definition of a protocol.
