FIELD: communication equipment.
SUBSTANCE: invention relates to a method of determining an uplink signal transmission parameter. Method comprises: determining, by a terminal device, a first set of SRS signal resources; reception by terminal device of first indicating information, sent by a network device and used to indicate a set of target SRS signal resources and instruction of the terminal device to transmit aperiodic SRS signal; determining, by the terminal device, a set of target SRS signal resources from the first set of SRS signal resources according to the first indication information, wherein the set of SRS signal target resources is a subset of the first set of SRS signal resources; sending, by the terminal device, an aperiodic SRS signal to a network device in the SRS signal resource in the set of target SRS signal resources; receiving, by the terminal device, a second pointing information sent by the network device and used to indicate the target SRS signal resource in the SRS signal target resource set; and determination by terminal device of transmission parameter used for uplink signal transmission according to SRS signal target resource. At that, transmission parameter contains at least one of following: beamforming weighting coefficient; indicating precoding information; antenna panel for uplink signal transmission; antenna port for uplink signal transmission; level number for uplink transmission; a modulation and coding scheme for uplink transmission.
EFFECT: technical result consists in provision of efficient use of probing reference signal resource (SRS signal).
