Problems solved by technology

However, the current IMT-Advanced system does not define a substantial frame structure, and specifically, in the case of IEEE802.16m, if multiple frames are individually designed for each bandwidth, the system complexity will increase
In addition, when the length of the cyclic prefix (CP) of the frame is variably set, the frame structure changes, and in this case, when a single communication system uses two frame structures respectively having different CP lengths, a corresponding The problem of interference between neighboring cells

Abstract

The present invention relates to a method and to an apparatus for data transmission using a frame in a broadband wireless communication system. The method for data transmission according to the present invention comprises the steps of setting a data frame for transmitting and receiving data through a downlink and an uplink, and transmitting and receiving data through the set data frame. The data frame includes at least one or more first subframes, and at least one or more second subframes constituted by a number of data symbols different from the number of data symbols of the first subframes.

Description

[0001] This application is a divisional application of the original patent application number 200980151718.8 (international application number: PCT / KR2009 / 007646, filing date: December 21, 2009, invention name: data transmission method and device using data frames) . technical field [0002] The present invention relates to a common frame structure applicable to various bandwidths and methods and devices for transmitting and receiving data using the frame structure. Background technique [0003] According to communication technology, services provided by mobile communication systems have gradually evolved into various services including packet data transmission / reception services to transmit large amounts of data, multimedia broadcast services, and voice communication services. [0004] Currently operating third-generation communication services such as WCDMA allow transmission and reception of large amounts of data as well as voice data at a higher transfer rate, and in ord...
