This annex gives further information needed for understanding and implementing 6.4D.4. The following terms should be understood as follows:
– Relative phase error: refers to the phase difference between signals at different antenna ports, which should be ideally 0. It should be understood as for a slot i.e. (slot) relative phase. It is calculated based on DMRS symbols of that slot or on SRS symbols.
– Difference of relative phase error: refers to the difference between the relative phase error determined per slot and the relative phase error determined based on the SRS transmitted.
