5.5.1.7 Advanced
Caution: Most, if not all, of the LTE advanced settings should be left with their
default values. Any modification should be determined only by experienced wireless
professionals.
Each Advanced sub-menu and field is described in this section (Figure 5-40).

5.5.1.7.1 Power Control Parameters
Refer 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 power
management (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 power
p
CRS
(dBm) is:
p
CRS
= 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 the
parameter pb set under the Power Control Parameters . The default is 1.
