name: LAI
full_form: Location Area Identity
context: UE also estimates CPICH Ec/Nt (C/I) for each cell in its pilot active set for the current slot. The pilot Ec/Nt information for the selected cell is then also fed back on an uplink dedicated control channel. The Node B then uses the C/I estimate to determine the modulation and coding level for that users subsequent frame and possibly also for setting scheduling priorities. The simulation results presented below compare throughput and residual FER statistics with and without FCS enabled. The cell selection update rate is once every 3.33ms. The FCS and CPICH measurement delay, as shown in Figure 31 below, is about 10ms. Figure 31. Time diagram of FCS and CPICH measurement delay Table 24. FCS Disabled with Max C/I Scheduler Table 25. FCS Enabled with Max C/I Scheduler From Table 26 and Table 27 for the Round Robin scheduler see somewhat larger throughput improvements with FCS on compared to the Maximum C/I scheduler. Figure 32 (based on center cell only results) illustrates FCS benefits
description: The Location Area Identity (LAI) is a unique identifier used in cellular networks to identify a location area, which is a group of cells. It is used by the Radio Network Controller (RNC) to forward NAS messages to the Core Network (CN) domain and is included in the INITIAL UE MESSAGE message along with other information such as CN domain indicator.
explanation: The context provided highlights the use of LAI in the Initial UE Message procedure, specifically in the selection of the CN node and the forwarding of NAS messages. The mention of LAI being indicated to the UE by the UTRAN via the current RRC connection and its inclusion in the INITIAL UE MESSAGE message suggests that it is an identifier used for location purposes, hence classified as an Identifier.
