Claim 12:
13. A non-transitory computer-readable storage medium, comprising a computer program, wherein the computer program, when executed by a computer, causes the computer to perform operations comprising:
determining two pieces of quasi co-location (QCL) information of antenna ports of a demodulation reference signal (DMRS) of a data channel based on a predetermined rule in response to determining that a QCL configuration information indicates a QCL type D, and an offset between the data channel and a reception of downlink control information (DCI) scheduling the data channel is less than a threshold, wherein the QCL configuration information includes at least two transmission configuration indication (TCI) states, and the predetermined rule comprises one piece of indication information with smallest identifiers among an indication information set, wherein each indication information in the indication information set is associated with two reference signal (RS) sets and is used to indicate QCL information of antenna ports of the DMRS, each of the two RS sets comprising one or more RS;
and
performing a communication on the data channel based on the determined two pieces of QCL information of the antenna ports of the DMRS of the data channel.
