Method and device for representing quasi co-location parameter configuration, and transmitting and receiving apparatus

A device for representing a quasi co-location (QCL) parameter configuration, comprising:

• a processor configured to:
• acquire a second QCL characteristic parameter set comprising at least some of characteristic parameters of a first QCL characteristic parameter set;
• and
• send configuration information of the second QCL characteristic parameter set to a receiving terminal.

A method for representing a quasi co-location (QCL) parameter configuration, comprising:

• receiving, by a receiving terminal from a transmitting terminal, a signaling that indicates a configuration information of a second QCL characteristic parameter set;
• demodulating the signaling to acquire the configuration information of the second QCL characteristic parameter set, wherein the second QCL characteristic parameter set comprises at least some of characteristic parameters of a first QCL characteristic parameter set,
• wherein the characteristic parameters represent characteristics of a radio propagation channel, and
• wherein the characteristic parameters comprise an average delay or a frequency offset.
