Cell Reference Symbol Power Configuration

The Adjustable Cell Reference Symbol (CRS) Power feature (FAJ 121 3049) was introduced in L14A. This feature enables flexible setting of the CRS power (Pa) and also enables flexible setting of the type-B resource element power (PDSCH).

The feature improved flexibility for tuning and optimization of downlink resource element power allocation and can lead to improved DL throughput, such as in high dense networks.

The feature controls two factors:

• CRS Power Boost setting (Pa) in the range +3dB to -3dB, previously this value had been fixed by system constant to +3dB.

• Type-B resource element boosting (Pb/Pa) in the range {5/4, 1, 3/4, 1/2}, previously this value had been fixed by a system constant to 1.
