Patent Images
1. An operating method of a terminal in a wireless communication system, the operating method comprising:
- receiving uplink (UL) resource allocation information through a downlink (DL) subframe;
identifying at least one UL subframe corresponding to the DL subframe based on a ratio of the DL to the UL;
identifying, based on the UL resource allocation information, a number of the at least one UL subframe, and at least one index of the at least one UL subframe, a 2-bit value indicating a transmission time interval (TTI) type and a location of one UL subframe within the at least one UL subframe; and
transmitting UL data based on the location of the UL subframe and the TTI type indicated by the 2-bit value of the UL resource allocation information,wherein the 2-bit value is set to one of;
‘
00’
indicating that the TTI type is a long TTI,‘
01’
indicating that the TTI type is a default TTI and a first UL subframe within the at least one UL subframe,‘
10’
indicating that the TTI type is the default TTI and a second UL subframe within the at least one UL subframe, and‘
11’
indicating that the TTI type is the default TTI and a third UL subframe within the at least one UL subframe.

Abstract
An apparatus and a method for indicating uplink resource allocation in a broadband wireless communication system are provided. The method includes decoding an UpLink (UL) resource allocation Information Element (IE) in a received DownLink (DL) subframe, extracting an indicator field value from the decoded UL resource allocation IE, the indicator field value indicating a Transmission Time Interval (TTI) type for a resource allocated to the terminal and a UL subframe location, and transmitting UL data through a resource allocated to the terminal based on the extracted indicator field value.
