Patent ID: 11916705
Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 10:
11. A communication device, comprising:
one or more processors configured to determine a time-domain density of a phase tracking reference signal and a frequency-domain density of the phase tracking reference signal; and
a communications interface configured to send or receive the phase tracking reference signal based on the time-domain density of the phase tracking reference signal and the frequency-domain density of the phase tracking reference signal;
wherein the time-domain density of the phase tracking reference signal corresponds to a bandwidth part and a modulation and coding scheme (MCS);
wherein the frequency-domain density of the phase tracking reference signal corresponds to the bandwidth part and a scheduled bandwidth;
wherein the bandwidth part comprises multiple consecutive physical resource blocks in the frequency domain; and
wherein the bandwidth part corresponds to one or more subcarrier spacings.
