Reference Signal Power Boosting Gain for LTE
Power boosting in LTE is mainly perform on the Reference signal. However, since the radio power is shared equally by all Resources element, the power allocation for each RE is fixed.
By increasing the number of Resources element being used as Reference Signal, the RS can be “boosted’ by 2x (3dB), 3x (4.7dB) or 4x (6dB) accordingly.
Power Boosting value = 0 if there is no extra resources used.
Default Power boosting = 1 (2x) for network planning
Alternatively, reliability of information transmission can also be “boosted” not by radio transmission power but by adjusted to a lower modulation level (MCS adjustment).
Remote Radio Unit and eNodeB Portfolio
The introduction of Remote Radio Unit allow the reduction of cable loss by up to 3dB for both uplink and downlink, depending on the actual length of the cable run from top of base station rack to the antenna location. Possible Radio configurations on offer range from 20W per carrier, single transmit branch to two transmit at 40W each.
Reference Signal Power Boosting Gain for LTE
Reference signal power boosting in LTE is used to enhance the strength of reference signals, which are crucial for tasks like cell search and mobility management. I’d recommend thinking of it as a way to make sure the network’s reference signals are strong enough for devices to accurately measure and track signals, even in challenging conditions. By boosting the reference signal power, you can improve the overall performance of the network, especially in areas with weak coverage or high interference, ensuring more reliable connections for users.
