name: PSD
full_form: Power Spectral Density
context: methodology described in clause 6.3). A smaller or no coverage loss for PUSCH is expected if the target data rate for RedCap UE is reduced. As seen from Table 9.1.3-2 and Table 9.1.3-3, for DL PSD 33 dBm/MHz, all the downlink channels are not coverage limited for both 1 Rx and 2 Rx RedCap UEs. For DL PSD 24 dBm/MHz and 2 Rx RedCap UE, a coverage degradation of approximately 1.1 dB is observed for Msg2 as seen from Table 9.1.3-4. For DL PSD 24 dBm/MHz and 1 Rx RedCap UE, a coverage degradation of approximately 6.2 dB, 2.5 dB and 0.8 dB, respectively is observed for Msg2, Msg4 and PDCCH CSS as seen from Table 9.1.3-5. It should be noted that for DL PSD 24 dBm/MHz case, Msg2 results are based on no TBS scaling. Table 9.1.3-2: Coverage loss (dB) for 2Rx RedCap UE in Urban 4 GHz with 33 dBm/MHz PSD (Option 3) Note: All sources assume no TBS scaling for Msg2 evaluation. Table 9.1.3-3: Coverage loss (dB) for 1Rx RedCap UE in Urban 4 GHz with 33 dBm/MHz PSD (Option 3) Note: All sources assume
description: Power Spectral Density (PSD) is a parameter used to measure the power of a signal per unit bandwidth. In the context of 3GPP TS 38.875, PSD is used to evaluate the coverage loss for different downlink channels in various scenarios.
explanation: The provided text explicitly mentions 'DL PSD' (Downlink Power Spectral Density) as a parameter used in tables and calculations to assess coverage degradation for RedCap UEs. This indicates that PSD is being treated as a measurable attribute of the network, fitting the definition of a Parameter.
