Abstract:
1. A method for configured an uplink Hybrid Automatic Repeat reQuest (HARQ) process using a frequency division duplex (FDD) frame structure at a relay node in a wireless communication system, the method comprising: receiving information on a downlink subframe pattern from a base station, wherein the downlink subframe pattern is defined as a bitmap having a size of 8 bits; allocating downlink subframes between a base station and the relay node based on the downlink subframe pattern; allocating uplink subframes between the base station and the relay node based on the allocated downlink subframes; and assigning at least one uplink HARQ process to the allocated uplink subframes, wherein a number of the at least one uplink HARQ process is determined by using a decimal equivalent of the bitmap.
