The present invention discloses a method and an apparatus for reporting an unlicensed spectrum capability, and relates to the field of broadband access technologies, so as to resolve a problem that, when an LTE base station device directly configures an unlicensed spectrum resource for user equipment, a case may occur in which the user equipment cannot use a spectrum resource allocated to the user equipment, thereby affecting data transmission performance of the user equipment. The method specifically includes the following: UE reports a list of unlicensed spectrums that can be supported by the UE and a maximum bandwidth of each unlicensed spectrum to a serving base station of the UE, so that the serving base station of the UE can configure an unlicensed spectrum resource for the UE according to a received unlicensed spectrum capability parameter. Therefore, a base station can configure an unlicensed spectrum resource according to unlicensed spectrum capabilities that can be supported by different UEs.

The present invention 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 sub frame 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.
