Abstract
Disclosed is a phase noise compensation method performed by a terminal. The terminal may: receive a signal, wherein the signal is transmitted via multiple symbols; estimate phase noise for each of multiple phase noise estimation sections included in the multiple symbols in the time domain, wherein each of the multiple phase noise estimation sections is included in cyclic prefixes (CPs) included in the respective multiple symbols; and perform the phase noise compensation on the multiple symbols in the time domain on the basis of the estimated phase noise.
Claims21
A method of performing phase noise compensation by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a signal, wherein the signal is transmitted through a plurality of symbols,
- estimating phase noise for each of a plurality of phase noise estimation durations included in the plurality of symbols in a time domain, wherein each of the plurality of phase noise estimation durations is included in a cyclic prefix (CP) included in each of the plurality of symbols;
- and
- performing the phase noise compensation on the plurality of symbols in a time domain based on the estimated phase noise.
A user equipment (UE), the UE comprising:
- at least one memory storing instructions;
- at least one transceiver;
- and
- at least one processor coupling the at least one memory and the at least one transceiver, wherein the at least one processor execute the instructions,
- wherein the at least one processor:
- receives a signal, wherein the signal is transmitted through a plurality of symbols,
- estimates phase noise for each of a plurality of phase noise estimation durations included in the plurality of symbols in a time domain, wherein each of the plurality of phase noise estimation durations is included in a cyclic prefix (CP) included in each of the plurality of symbols;
- and
- performs the phase noise compensation on the plurality of symbols in a time domain based on the estimated phase noise.
(canceled)
A base station (BS), the BS comprising:
- at least one memory storing instructions;
