Table 1 Required power back-off values for different types of CA and uplink resource allocation schemes
From: Radio resource management for uplink carrier aggregation in LTE-Advanced
CA type | Resource allocation | Required power back-off (dB) |
|---|---|---|
Intra-band CA with one RF front-end | Multi-CC transmission | \( {P}_{\mathrm{MPR}}^{\mathrm{CA}} \) |
Single-CC with multi-cluster | \( {P}_{\mathrm{MPR}}^{\mathrm{SC}} \) | |
Single-CC with single-cluster | 0 | |
Inter-band CA with dual RF front-ends | Multi-CC with single-cluster | 2 |
Multi-CC with multi-cluster | \( {P}_{\mathrm{MPR}}^{\mathrm{SC}} \) + 2 |
