Method, device and communication device for determining beam information

A method for determining beam information, comprising:

• determining, by a network side device, a plurality of quasi co-location (QCL) parameter configurations of a reference signal, wherein the QCL parameter configurations are used to configure a plurality of QCL parameters of the reference signal;
• and
• indicating, by the network side device, at least one target QCL parameter from the plurality of QCL parameters, to the terminal;
• wherein the target QCL parameter indicated by the network side device is determined based on an association relationship between the QCL parameters of the reference signal and pieces of transmission information, and the transmission information comprises at least one of a transmission time unit, a scheduled transmission, a transmission channel or a transmission signal.

A device for determining beam information, applied to a terminal, comprising a memory, a transceiver, and a processor;

• wherein the memory is configured to store a computer program, the transceiver is configured to transmit and receive data under control of the processor, and the processor is configured to read the computer program in the memory to perform following operations:
• obtaining a plurality of quasi co-location (QCL) parameter configurations of a reference signal, wherein the QCL parameter configurations are used to configure a plurality of QCL parameters of the reference signal;
• and
• determining at least one target QCL parameter from the plurality of QCL parameters of the reference signal based on a predefined rule or an indication from a network side device;
• wherein the predefined rule or the indication from the network side device is determined based on an association relationship between the QCL parameters of the reference signal and pieces of transmission information, and the transmission information comprises at least one of a transmission time unit, a scheduled transmission, a transmission channel or a transmission signal.
