A method for obtaining a Transmission Reception Point, TRP, information, comprising: receiving (S101) a control information which is adapted to trigger a signal or a channel; obtaining (S102) a Transmission Configuration Indication, TCI, comprised in the control information; and obtaining (S103), according to the TCI, a TRP which participates in transmitting the signal or the channel triggered by the control information; characterized in that a number of the TCI comprised in the control information is one, where the TCI comprises multiple Reference Signal, RS, groupings, and each RS grouping has a corresponding TRP; wherein obtaining, according to the TCI, a TRP which participates in transmitting the signal or the channel triggered by the control information comprises: detecting whether a Quasi Co-Located, QCL, configuration corresponding to each RS grouping meets a preset condition; and when a QCL configuration corresponding to a first RS grouping does not meet the preset condition, determining that a TRP corresponding to the first RS grouping participates in transmitting the signal or the channel triggered by the control information; or in that a number of the TCI comprised in the control information is more than one, and each TCI has a corresponding TRP; wherein obtaining, according to the TCI, a TRP which participates in transmitting the signal or the channel triggered by the control information comprises: detecting whether a value of a first TCI comprised in the control information is a preset value; and when the value of the first TCI is equal to the preset value, determining that a TRP corresponding to the first TCI does not participate in transmitting the signal or the channel triggered by the control information. receiving (S101) a control information which is adapted to trigger a signal or a channel; obtaining (S102) a Transmission Configuration Indication, TCI, comprised in the control information; and obtaining (S103), according to the TCI, a TRP which participates in transmitting the signal or the channel triggered by the control information; characterized in that a number of the TCI comprised in the control information is one, where the TCI comprises multiple Reference Signal, RS, groupings, and each RS grouping has a corresponding TRP; wherein obtaining, according to the TCI, a TRP which participates in transmitting the signal or the channel triggered by the control information comprises: detecting whether a Quasi Co-Located, QCL, configuration corresponding to each RS grouping meets a preset condition; and when a QCL configuration corresponding to a first RS grouping does not meet the preset condition, determining that a TRP corresponding to the first RS grouping participates in transmitting the signal or the channel triggered by the control information; or in that a number of the TCI comprised in the control information is more than one, and each TCI has a corresponding TRP; wherein obtaining, according to the TCI, a TRP which participates in transmitting the signal or the channel triggered by the control information comprises: detecting whether a value of a first TCI comprised in the control information is a preset value; and when the value of the first TCI is equal to the preset value, determining that a TRP corresponding to the first TCI does not participate in transmitting the signal or the channel triggered by the control information. <EOS>
