description The invention provides a DTX determination method and apparatus of a physical uplink control channel, and a base station. The method includes the steps: receiving, by the base station, an uplink signal in a PUCCH resource block of target UE at a first moment; determining that a PUSCH signal sent from the target UE is received at a second moment, performing channel estimation for the uplink signal through a preset algorithm to obtain a channel estimate frequency domain result sequence HPUCCH, and performing channel estimation for the PUSCH signal through the preset algorithm to obtain a channel estimate frequency domain result sequence HPUSCH, the second moment being prior to the first moment; and determining a DTX determination result of the target UE at the first moment on the basis of the sequence HPUCCH, the sequence HPUSCH and a preset DTX threshold. The accuracy of PUCCH channel DTX determination is improved to a certain extent, and the DTX state of the target UE can be accurately determined even in an environment with much interference.
