Reference Signal Received Power

RSRP is the linear average of the received reference signal level. These reference signals, which are specific to each cell, are transmitted using the source elements. Thanks to RSRP, it is possible to compare the strengths of signals from individual cells in LTE networks. It is important parameter for cell selection or handover. RSRP is the equivalent of the RSCP parameter used in UMTS systems.

RSRP calculation

Output power of eNodeB can be variable and depends on the HW and SW configuration. These values are typical scenario for FDD-LTE. HW also support single (1x60W) or multiple sectors (3x60W). It is possible to offer a similar set-up for TDD-LTE. Source: The LTE-advanced deployment handbook : the planning guidelines for the fourth generation networks

RSRP calculation

In case that 100% PRB is active (full load) without noise and interference. Based on formula from book LTE Optimization Engineering Handbook by Zhang Xincheng.
