under the condition that the resource configuration information comprises downlink reference signal resources with the same resource identifiers, the signal relay equipment determines that downlink transmission beams on the downlink reference signal resources are the same; for example, on the CSI-RS resources configured with the same ID, the signal relay device transmits the CSI-RS using the same downlink transmission beam;

when the resource configuration information configures a quasi co-located QCL relationship of a downlink reference signal, the signal relay device determines that downlink transmission beam information for transmitting the downlink reference signal is: the same beam as the reference signal indicated by the QCL relationship; for example, for transmission of information in which a QCL relationship (QCL type D) is configured, the signal relay apparatus transmits the information using the same beam as a reference signal indicated by the QCL relationship;

when the transmission activation information indicates a transmission beam of a downlink reference signal, the signal relay device determines that downlink transmission beam information for transmitting the downlink reference signal is: a beam indicated by the transmission activation information;

if the downlink reference signal beams in the downlink reference signal resource set configured by the resource configuration information are not repeated, the signal relay equipment determines that the downlink reference signals in the downlink reference signal resource set correspond to different downlink transmission beams; for example, the CSI-RS resource set of the terminal is configured as "turn-off repetition", and the signal relay device may transmit CSI-RS in the CSI-RS resource set by using different beams;

For example, when the CSI-RS resource set is configured as "off repetition", the first reference beam is beam #2 in fig. 3, or beam #3 in fig. 4.

Optionally, if there is no indication of the first reference beam, the signal relay device may determine the transmission beam of the CSI-RS by itself, or determine the transmission beam of the CSI-RS according to a preset default beam. For example, if the base station does not indicate the first reference beam, the signal relay device determines a coarse transmission beam to be trained with reference to the omni-directional beam.
