A channel measurement method, comprising: receiving, by a user equipment, first transmission control information; starting, by the user equipment, a semi-persistent channel measurement when the first transmission control information meets a first preset condition, wherein the first preset condition comprises at least following conditions: the first transmission control information is downlink control information, DCI, where the DCI has a preset format; the first transmission control information is associated with a semi-persistent channel measurement radio network temporary identifier, RNTI; the semi-persistent channel measurement RNTI being obtained based on a user identifier according to a correspondence table of the semi-persistent channel measurement RNTI and the user identifier; and a value of a first group of information in the first transmission control information meets a first preset rule when the DCI has the preset format, wherein the first group of information comprises a redundancy version, RV, and a hybrid automatic repeat request, HARQ process number, transmit power control, TPC, information, and a new data indicator, NDI, a value of a first group of information in the first transmission control information meets a first preset rule comprises all bits of the RV are 0, all bits of the HARQ process number are 0, all bits of the TPC information are 0 and all bits of the NDI are set to 0. receiving, by a user equipment, first transmission control information; starting, by the user equipment, a semi-persistent channel measurement when the first transmission control information meets a first preset condition, wherein the first preset condition comprises at least following conditions: the first transmission control information is downlink control information, DCI, where the DCI has a preset format; the first transmission control information is associated with a semi-persistent channel measurement radio network temporary identifier, RNTI; the semi-persistent channel measurement RNTI being obtained based on a user identifier according to a correspondence table of the semi-persistent channel measurement RNTI and the user identifier; and a value of a first group of information in the first transmission control information meets a first preset rule when the DCI has the preset format, wherein the first group of information comprises a redundancy version, RV, and a hybrid automatic repeat request, HARQ process number, transmit power control, TPC, information, and a new data indicator, NDI, a value of a first group of information in the first transmission control information meets a first preset rule comprises all bits of the RV are 0, all bits of the HARQ process number are 0, all bits of the TPC information are 0 and all bits of the NDI are set to 0. the first transmission control information is downlink control information, DCI, where the DCI has a preset format; the first transmission control information is associated with a semi-persistent channel measurement radio network temporary identifier, RNTI; the semi-persistent channel measurement RNTI being obtained based on a user identifier according to a correspondence table of the semi-persistent channel measurement RNTI and the user identifier; and a value of a first group of information in the first transmission control information meets a first preset rule when the DCI has the preset format, wherein the first group of information comprises a redundancy version, RV, and a hybrid automatic repeat request, HARQ process number, transmit power control, TPC, information, and a new data indicator, NDI, a value of a first group of information in the first transmission control information meets a first preset rule comprises all bits of the RV are 0, all bits of the HARQ process number are 0, all bits of the TPC information are 0 and all bits of the NDI are set to 0.
