Abstract
Embodiments of the present disclosure relate to methods, terminal device, network device and apparatuses for determining a Phase Tracking Reference Signal (PTRS) configuration parameter. In an embodiment of the present disclosure, the method of interference measurement comprises determining a PTRS transmission resource configuration parameter based on a resource allocation type to be used in data transmission. With embodiments of the present disclosure, it may determine different PTRS configuration parameters for different resource allocation types, and thus provide a more suitable PTRS configuration solution for different resource allocation cases.
Claims4
A method performed by a terminal device, comprising:
- determining a Phase Tracking Reference Signal (PTRS) transmission resource configuration parameter based on a waveform type to be used in data transmission, comprising
- determining, from a plurality of resource mappings of PTRS transmission, a resource mapping corresponding to a waveform type;
- and
- determining the PTRS transmission resource configuration parameter based on the resource mapping;
- and
- transmitting the PTRS based on the determined PTRS transmission resource configuration parameter.
A method performed by a network device, comprising:
- transmitting a Phase Tracking Reference Signal (PTRS) transmission resource configuration parameter to be used in data transmission, wherein the PTRS transmission resource configuration parameter is associated with a resource mapping, among a plurality of resource mappings, corresponding to a waveform type;
- and
- receiving the PTRS based on the PTRS transmission resource configuration parameter,
- wherein each of the plurality of resource mappings is for a different allocation mode in the same waveform type.
A terminal device, comprising:
- a processor configured to
- determine, from a plurality of resource mappings of Phase Tracking Reference Signal (PTRS) transmission, a resource mapping corresponding to a waveform type;
- and
- determine a PTRS transmission resource configuration parameter based on the resource mapping;
- and
- a transmitter configured to transmit the PTRS based on the determined PTRS transmission resource configuration parameter.
