S-CRITERION The cell selection criterion S is a pre-condition for suitable cells. The conditions for E-UTRAN, UTRAN FDD and GSM cells are listed in the figure. R – CRITERION –…

PLMN Selection Process in LTE The UE scans all RF channels in the UTRAN band according to its capabilities to find available PLMNs. On each carrier, the UE searches for…

The coding mode is called Regular Pulse Excited-Long Term Prediction (RPE-LTP). It works as follow: 8KHZ of sampling is performed first, then divided into frames with 20ms; every frame has…

The UE is requested to send either periodic or a periodic reports concerning • Rank indication (RI) Reports are applicable for closed- and open-loop spatial multiplexing. In case of open-loop…

Based on DCI formats In LTE Three types of allocation are used: type 0: DCI formats 1, 2, 2A type 1: DCI formats 1, 2, 2A type 2: DCI formats1A,…

A variety of scheduling strategies is available in LTE. The scheduling strategy is based on a certain metric. – Round-Robin. No quality indication is taken into consideration. The resources are…

Scheduling Principle Deployment of shared channels offers the possibility for scheduling. In this way information on varying channel conditions can be exploited to increase the overall throughput. Fast scheduling in…

Hybrid ARQ (HARQ) leads to higher efficiency in transmission and error correction. There is one HARQ entity per UE with 8 stop-and-wait processes for each HARQ entity. Both incremental redundancy…

Below is the List and How Intra RAT HO events in LTE. Event A1 : Serving becomes better than threshold Event A2 : Serving becomes worse than threshold Event A3…

If the IE “Filter coefficient” is received the UE applies filtering of the measurements for that measurement quantity according to the formula below. This filtering is performed by the UE…
