Uplink Power Control Calculation in LTE Transmit power of PUSCH in subframe i is defined by PPUSCH (i) = min{PMAX,10 log10 (MPUSCH (i)) + PO_PUSCH ( j) +α ( j) ⋅ PL + ΔTF (i) + f (i)} [dBm] Pmax: max. allowed power, MPUSCH: number of scheduled RBs, PL: pathless [dB]. ΔTF (i) = 10 … Read more
S-CRITERION The cell selection criterion S is a pre-condition for suitable cells. The conditions for E-UTRAN, UTRAN FDD and GSM cells are listed in the figure. R – CRITERION – CELL RESELECTION The cell reselection evaluation process depends on whether Hierarchical Cell Structure (HCS) is used or not. In order to perform cell reselection UE … Read more
Here I write down one basic idea of Spectrum reframing in LTE and why operators require spectrum reframing for LTE. Operators worldwide are looking forward to new LTE technologies deployment but not every one of them possess brand new spectrum required for LTE deployment. As a result, many networks are expected to perform some level … Read more
