14.1.6 Report quantities in intra-frequency measurements

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

The quantities that the UE shall report to UTRAN when the event is triggered for an intra-frequency measurement are given by the IE "Intra-frequency reporting quantity" stored for this measurement and can be the following:

1 SFN-SFN observed time difference

2 Cell synchronisation information

3 Cell Identity

4 Downlink E_c/N₀ (FDD).

5 Downlink path loss.

For FDD:

Pathloss in dB = Primary CPICH Tx power – CPICH RSCP.

– For Primary CPICH Tx power the IE "Primary CPICH Tx power" shall be used. The unit is dBm.

– CPICH RSCP is the result of the CPICH RSCP measurement. The unit is dBm.

For TDD:

Pathloss in dB = Primary CCPCH TX power – Primary CCPCH RSCP.

– For Primary CCPCH TX power the IE "Primary CCPCH TX Power" shall be used. The unit is dBm.

– Primary CCPCH RSCP is the result of the Primary CCPCH RSCP measurement. The unit is dBm.

If necessary Pathloss shall be rounded up to the next higher integer.
Results higher than 158 shall be reported as 158.
Results lower than 46 shall be reported as 46.

6 Downlink received signal code power (RSCP) after despreading (of a primary CPICH for FDD, and of a primary CCPCH for TDD).

7 ISCP measured on Timeslot basis. (TDD)

8 Proposed TGSN (TDD)

A description of those values can be found in [7] and [8].
