Claim:
1. A method of receiving a frame by a station (STA) in a wireless communication system, the method comprising: receiving, by the STA, a frame including a first data part and a second data part from an access point (AP); wherein the frame further includes information used for determining, by the STA, whether to perform decoding of at least one of the first data part and the second data part, determining, by the STA, whether to perform the decoding of at least one of the first data part and the second data part of the frame using the information included in the frame; performing, by the STA, the decoding of at least one of the first data part and the second data part when it is determined that the decoding is to be performed, wherein whether to perform the decoding is determined based on a change of at least one of the first data part and the second data part; transmitting, by the STA, a power save-poll (PS-Poll) frame to the AP based on the decoded frame; and receiving, by the STA, data from the AP based on the PS-Poll frame.
