Upstream OFDMA Receive Power is a PNM Test described in [PHYv3.1] Upstream Channel Power section. The CmtsUsOfdmaRxPwrTable defines the management interface for the operator to configure, execute, and monitor the Upstream OFDMA Receive Power test. The purpose of the upstream channel power metric is to provide an estimate of the received power in a specified OFDMA channel at the F connector input of the CCAP line card for a given user. The measurement is based on upstream probes, which are typically the same probes used for pre-equalization adjustment. The CCAP measures the total power of the probe subcarriers received from the CM. For channels without boosted pilots, the CCAP calculates the average power per subcarrier (Paverage) and then calculates the power normalized to 1.6 MHz as a)Paverage + 10 * log10(32) for 50 kHz subcarrier spacing, or as b)Paverage + 10 *log10(64) for 25 kHz subcarrier spacing. For channels with boosted pilots, the CCAP calculates the average power per subcarrier (Paverage) and then calculates the power normalized to 1.6 MHz as a)Paverage + 10 * log10(32) + 1 dB for 50 kHz subcarrier spacing, or as b)Paverage + 10 *log10(64) + 0.5 dB for 25 kHz subcarrier spacing. NOTE: The CCAP would also use that adjusted value for comparison with the Target Receive Power for the purposes of transmit power adjustments in the RNG-RSP. When executing the Measure Upstream OFDMA Receive Power test the CCAP must provide probe opportunities and make measurements over the number of averages configured in the column CmtsUsOfdmaRxPwrNumAvgs. The CCAP may support simultaneous Upstream OFDMA Rx Power tests on more than one OFDMA channel at a time. The CCAP should create a row in the docsPnmCmtsUsOfdmaRxPwrTable table for each ifIndex of an upstream channel.
