Abstract

A method and apparatus for transmitting data using a frame in a broadband wireless communication system are disclosed. The method for transmitting and receiving data in a broadband wireless communication system includes: setting a data frame for transmitting and receiving data through uplink and downlink; and transmitting and receiving data through the set data frame, wherein the data frame includes one or more first subframes and one or more second subframes including a different number of data symbols from that of data symbols of the first subframe.

Claims

1. A method for transceiving signals using a predetermined frame structure in a broadband wireless communication system, the method comprising:

configuring, by a controller, a Time Division Duplex (TDD) frame according to the predetermined frame structure, the TDD frame having a channel bandwidth of 7 MHz, and controlling transmission and receipt of data through the TDD frame; and

transceiving a signal through the TDD frame according to the predetermined frame structure,

wherein a Cyclic Prefix length of the TDD frame corresponds to 1/16 of an effective symbol length,

wherein the TDD frame includes a downlink interval and an uplink interval that is located subsequent to the downlink interval,

wherein a Transmit Transition Gap (TTG) interval is located between the downlink interval and the uplink interval,

wherein a Receive Transition Gap (RTG) interval is located next to a last uplink subframe of the uplink interval,

wherein a total length of the TTG interval and the RTG interval is 240 μ

s,

wherein the downlink interval includes four downlink subframes comprising three type-1 downlink subframes that include six Orthogonal Frequency Division Multiple Access (OFDMA) symbols and a type-3 downlink subframe that includes five OFDMA symbols,

wherein a first downlink subframe of the three type-1 downlink subframes is configured to include a superframe header,

wherein the type-3 subframe is located subsequent to the three type-1 downlink subframes,

wherein the uplink interval includes two uplink subframes comprising only a type-1 uplink subframe that includes six OFDMA symbols,

wherein the type-1 uplink subframe has a length of 0.816 ms and the type-3 downlink subframe has a length of 0.680 ms,

wherein the type-1 uplink subframe has a same size as a subframe included in a Frequency Division Duplex (FDD) frame having a channel bandwidth of 7 MHz, the FDD frame configured to have a Cyclic Prefix length corresponding to 1/16 of an effective symbol length.
