Following is a couple of typical p-a, p-b configuration that we normally see. Understanding PA / PB in LTE The power allocation of the downlink traffic channel PDSCH in LTE uses a fixed power allocation method, which involves two parameters, PA and PB, which are difficult to understand. Rather than employing a single PA for each mode or band in a device, manufacturers must now employ multimode, multiband PAs that can help reduce costs and minimize board real estate. It can be beneficial to increase the transmit power of resource elements carrying reference signals compared to elements carrying data. Pa is the power ratio of an A symbol's resource elements to the reference signal, while Pb is the ratio for B symbols. The impact on throughput is unclear as it may lower throughput due to lower reported channel quality or increase it by LTE/4G Power Efficiency Between PA(CRS Gain) and PB(Type B) A tradeoff between improving throughput or improving coverage The PA. 2-1), but some vendors allow you to set PDSCH power offsets from RS RE manually.

That is, the pilot power for symbols including pilot symbols accounts for 1/3. It recommends values for the parameters PA and PB, which are used to boost or de-boost the RS power and PDSCH Type B power respectively. The Impacts of LTE and 802. PA/PB theory description. The max transmit power is determined by the greater of the max power of Type A or Type B symbols. Parameter PA sets the power of PDSCH type A RE relative to cell‐specific RS, PB sets the power relation between PDSCH type B RE, and PDSCH type A RE (ρB/ρA in 3GPP). However, since the radio power is shared equally by all Resources element, the power allocation for each RE is fixed. - It includes a power amplifier (PA) and power balances (PB) across subcarriers ranging from -6 to 3 dBm. But practically you can take this value as a UE class power defined as in the . It explains that an eNodeB can transmit reference signals at a higher power level than data signals.
