655.5.1.7 AdvancedCaution: Most, if not all, of the LTE advanced settings should be left with theirdefault values. Any modification should be determined only by experienced wirelessprofessionals.Each Advanced sub-menu and field is described in this section (Figure 5-40).Figure 5-40: Advanced5.5.1.7.1 Power Control ParametersRefer to Table 5-20 for a description of the Power Control Parameters.Information about power control:If the transmit power is set to fixed, the value is set to single. If the transmit powermanagement (TPM) is set to enabled, the eNB can adjust its transmit power automatically;only the two values for top and bottom boundaries are set, separated by a comma.Following is the formula for calculating the reference signal power using total power:Total power is P TX (mW), bandwidth is Bw (MHz), then the reference signal powerpCRS (dBm) is:pCRS = 10 * lg(P TX) – 10 * lg(12 * 100 * Bw / 20) + 10 * lg(1 + P B)where:Bw is the parameter carrierBwMhz under Quick Setting.P B is the power parameter for Physical Downlink Shared Channel (PDSCH), which is theparameter pb set under the Power Control Parameters. The default is 1.
