Method and apparatus for transmitting/receiving data in a wireless communication system

摘要

The present invention relates to a method and apparatus for transmitting/receiving data in a wireless communication system. According to one aspect of the present invention, a data receiving method is provided wherein a mobile station in a wireless communication system uses a frame including a first subframe in which a physical downlink shared channel (hereinafter, referred to as “PDSCH”) includes a first cyclic prefix (hereinafter, referred to as “CP”) and a second subframe in which the PDSCH includes a second CP, wherein the data receiving method comprises a step in which the mobile station receives information on the length of the first CP from a base station, receives data from the base station through the first subframe, and removes the CP of the data using the information on the length of the first CP. The first CP and the second CP have different lengths.

主权项

1. A method for receiving data at a mobile station (MS) in a wireless communication system, the method comprising:
receiving information indicating a subframe index, the subframe indicated by the subframe index including one or more OFDM (Orthogonal Frequency Division Multiplexing) symbols using extended CP (Cyclic Prefix); and transmitting uplink data in a uplink subframe by consideration of the subframe index, wherein, if the uplink subframe is the subframe indicated by the subframe index, one or more uplink subframes in which the uplink data is re-transmitted include one or more OFDM symbols using the extended CP, and wherein, if the uplink subframe is not the subframe indicated by the subframe index, one or more uplink subframes in which the uplink data is re-transmitted include one or more OFDM symbols using normal CP.
