US 11,122,589 B2 · Method and device for allocating PTRS to resource block in wireless communication system

Abstract

According to an embodiment of the present specification, a method for transmitting, by a base station, a signal for eliminating phase noise by a terminal in an mmWave communication system may be provided. A method for transmitting a signal for eliminating phase noise may comprise the steps of: generating a PTRS; allocating the PTRS to one or more resource blocks included in a scheduled bandwidth; and transmitting the allocated PTRS, wherein an interval between the one or more resource blocks, to which the PTRs are allocated, is determined on the basis of the scheduled bandwidth.

Dependent claims

A method of transmitting, by a base station, a signal for enabling a user equipment (UE) to eliminate phase noise in a millimeter wave (mmWave) communication system, the method comprising:

generating a phase tracking reference signal (PTRS);
allocating the PTRS to one or more resource blocks included in a scheduled bandwidth;
and
transmitting the allocated PTRS,
wherein an interval between the one or more resource blocks to which the PTRS is allocated is determined based on the scheduled bandwidth, and
wherein indices of the resource blocks to which the PTRS is allocated are shifted based on at least one of identification (ID) of the UE or a maximum number of shiftable resource blocks.

A base station for transmitting a signal for enabling a user equipment (UE) to eliminate phase noise in a millimeter wave (mmWave) communication system, the base station comprising:

a receiver configured to receive a signal from an external device;
a transmitter configured to transmit a signal to an external device;
and
a processor configured to control the receiver and the transmitter,
wherein the processor is configured to:
generate a phase tracking reference signal (PTRS);
allocate the PTRS to one or more resource blocks included in a scheduled bandwidth;
and
control the transmitter to transmit the allocated PTRS, and
wherein an interval between the one or more resource blocks to which the PTRS is allocated is determined based on the scheduled bandwidth, and
wherein indices of the resource blocks to which the PTRS is allocated are shifted based on at least one of identification (ID) of the UE or a maximum number of shiftable resource blocks.
