Abstract: The present disclosure relates to the field of communications technologies, and provides a semi-persistent scheduling method and user equipment. The semi-persistent scheduling method includes: determining a constant subframe set in a TDD frame, where an uplink and downlink attribute of each subframe in the constant subframe set remains unchanged when an uplink and downlink proportion configuration of the TDD frame dynamically changes; and performing SPS transmission in a subframe, in the constant subframe set, whose uplink and downlink attribute is the same as a transmission direction of the SPS transmission. In this way, SPS transmission can be normally performed without being affected by a flexible subframe in a case in which a TDD uplink and downlink proportion is dynamically configured for a UE.
