Control Channel Power
This measurement shows the power levels of key physical layer Control Channels and also
includes the numerical results table described in the
section above. EVM per
control channel is also available, as well as a table view showing the power in both
per-resource-element and total power formats. See
Ref Signal (RS) Power
Reference Signal power displayed in dBm. The reference signal is used for downlink channel
estimation.
P-SS Power
Primary Sync Signal power displayed in dBm or Watts. The primary sync signal is used to
obtain slot synchronization. It contains information needed for cell search.
S-SS Power
Secondary Sync Signal power displayed in dBm or Watts. The secondary sync signal is used
to obtain frame synchronization and cell identity. It contains information needed for cell
search.
PBCH Power
Physical Broadcast Channel Power. This physical channel carries system information for user
equipment (UE) requiring access to the network.
PCFICH Power
Physical Control Format Indicator Channel Power. This channel provides information to
enable the UE to decode the PDCCH and PDSCH channels.
PHICH Power
Physical Hybrid Automatic Repeat Request Indicator Channel. Transmits the channel coded
HARQ indicator codeword used for error correction.
PDCCH Power
Physical Downlink Control Channel.
Ng
Ng is a parameter that determines the number of PHICH (Physical Hybrid ARQ Indicator
Channel) groups in a TD-LTE sub-frame (this number is constant for all sub-frames).
Tx Time Alignment
Measures the delay between the signals from different antennas at the antenna ports.
Modulation Summary
Modulation Summary displays the Ref Signal (RS) Power, Sync Signal (SS) Power,
EVM (rms), Freq Error (Hz and ppm), Cell ID and PBCH Power in a table format. Refer to
individual Modulation measurement descriptions for additional detail on each measurement.
