Abstract
The present disclosure relates to a wireless communication method (50), implemented by a terminal (20) in a wireless communication system (10), for exchanging data with a radio access network (11) of said wireless communication system, said method comprising: —(S50) determining a phase noise temporal coherence indicator representative of a temporal coherence of a phase noise affecting baseband signals obtained from radiofrequency signals received by the terminal, —(S51) transmitting said phase noise temporal coherence indicator to said radio access network (11) of the wireless communication system.

A wireless communication method, implemented by a terminal in a wireless communication system, for exchanging data with a radio access network of said wireless communication system, said method comprising:
- determining a phase noise temporal coherence indicator representative of a temporal coherence of a phase noise affecting baseband signals obtained from radiofrequency signals received by the terminal, said phase noise temporal coherence indicator being the measure of the mean correlation between phase noises introduced at times separated by a given delay, evaluated for different delays,
- transmitting said phase noise temporal coherence indicator to the radio access network of the wireless communication system.
A wireless communication method, implemented by a base station in a wireless communication system, for exchanging data with a terminal of said wireless communication system, said method comprising:
- determining a phase noise temporal coherence indicator for the terminal, representative of a temporal coherence of a phase noise affecting baseband signals obtained from radiofrequency signals received by said terminal, said phase noise temporal coherence indicator being the measure of the mean correlation between phase noises introduced at times separated by a given delay, evaluated for different delays,
- determining, for said terminal and based on the determined phase noise temporal coherence indicator, a temporal spacing for pilot signals to be transmitted by the base station to said terminal,
- transmitting signals to the terminal, said signals including data signals and pilot signals, said pilot signals being temporally spaced apart based on the temporal spacing determined for said terminal.
