hi guys
1/waht's the RSCP
2/what's the cell selection and re-selection

[Boraa]

RSCP
- CPICH RSCP is the Received Signal Code Power on one channelization code measured on the bits of the Primary CPICH
- The reference point is the antenna connector at the UE.
- Although the measurement of this quantity requires that the Primary CPICH is despread, it should be noted that the RSCP is related to a chip energy and not a bit energy.
- This measurement is used for cell selection and re-selection and for handover preparation, open loop power control and pathloss calculation.

Cell selection in idle mode

UE uses two criteria to select the cell to camp on .
The parameters for selection are broadcast in SIB3

Cell reselection in idle mode

2 different 3GPP UE algorithms
- Classical for mono-layer network
- Hierarchical Cell Structure (HCS) algorithm
. HCS Priority for Serving cell and Neighboring cells are introduced (between 0 and 7)

the two measurment used for reselection are RSCP and EcNo
