1. A method for determining a quasi co-location reference signal set, comprising:
determining first information according to signaling information and/or a predetermined rule; and
determining, according to the first information, a quasi co-location reference signal set of a port group comprised in a data channel and/or a signal, wherein the first information comprises at least one of the following: a time interval between the data channel and/or the signal and a control channel for scheduling the data channel and/or the signal, a number of reference signal elements of a control channel element, a number of reference signal elements of the data channel and/or the signal, an index of the reference signal elements of the control channel element, an index of the reference signal elements of the data channel and/or the signal;
wherein the data channel and/or the signal satisfies one of the following characteristics:
the time interval between the data channel and/or the signal and the control channel for scheduling the data channel and/or the signal is less than a predetermined threshold; or
a control channel for scheduling the data channel and/or the signal does not include TCI;
wherein in a case where the signal is an aperiodic measurement reference signal, determining the predetermined threshold according to following method:
in a case where capability information reported by a communication node belongs to a predetermined set of {14 time domain symbols, 28 time domain symbols, and 48 time domain symbols}, determining the threshold as the capability information reported by the communication node; or,
in a case where capability information reported by the communication node does not belong to the predetermined set of {14 time domain symbols, 28 time domain symbols, and 48 time domain symbol s}, determining the threshold as a fixed value of 48 time domain symbols;
wherein the communication node is a receiving communication node of the data channel and/or the signal.
