Abstract: A resource scheduling method for direct device to device communications in a communication system according to the present invention comprises the following steps: selecting a mobile communication terminal to communicating with a base station for each channel dividing mobile communication resources which the base station occupies; calculating a signal to interference noise ratio of the mobile communication terminal by assuming that each terminal pair for direct communications between the selected mobile communication terminal and the terminal located within the service coverage of the base station is allocated to each channel; comparing the signal to interference noise ratio of the mobile communication terminal calculated for each channel with a first threshold and determining the terminal pairs whose signal to interference noise ratios for each channel are greater than the first threshold as candidate members of a combination sharing the relevant channel; and determining whether the relevant channel is allocated to each candidate member of the combination determined for each channel. [Reference numerals] (300) Select a first combination consisting of the entire members of the combination corresponding to a relevant channel;(305) Select a first D2D pair having a maximum SINR among the members of the first combination;(310) Calculate an SINR in terms of a mobile communication terminal if the channel corresponding to the first combination is additionally allocated to the first D2Dpair;(315) If the channel corresponding to the first combination is additionally allocated to the first D2D pair, the SINR in terms of the mobile communication terminal is greater than a first threshold?;(320) Determine not to additionally allocate the channel corresponding to the first combination to the first D2D pair;(325) Assume that the channel corresponding to the first combination is additionally allocated to the first D2D, and calculate an SINR in terms of the D2D pairs to which the channel is already allocated;(330) Is each of SINRs in terms of the first D2D pair and in terms of the D2D pair to which the channel corresponding to the first combination including the first D2D pair is allocated greater than a second threshold?;(335) Delete the first D2D pair from the candidate members of the first combination;(340) Allocate a unit resource of the first combination to the first D2D pair;(345) Does a candidate member whose resource allocation is not determined exist among the candidate members of the first combination?;(AA) Start;(BB,DD,FF,HH) No;(CC,EE,GG) Yes

Abstract: PURPOSE: A method and a device for transmitting feedback information in a communication system including a user terminal having a various numbers of antennas are provided to effectively detect feedback information of corresponding user terminal without considering the number of antenna of a user terminal, thereby implementing effective frequency management on whole. CONSTITUTION: Multicast data packet is received from a base station(210) through downlink multicast transmission channel. If the multicast data packet is a multicast data packet which does not have an experience of succeeding a decoding in previous time, the multicast data packet is decoded and whether decoding of multicast data packet is succeeded or not is checked. A NACK signal is transmitted to base station through a common feedback channel. If a user terminal itself has at least two antennas, series which being corresponded to the antennas has orthogonality to each other.
