摘要： Provided is a scheduling apparatus and method for allocating resources to individual users in a multiantenna system. An upper layer determines resources to allocate to respective users one a long term, and provides the ratio to a scheduler. Then the scheduler determines coefficients appropriate for the provided ratio. On the assumption that a statistical channel characteristic for a user is constant for a predetermined time, the scheduler determines a channel capacity average and a standard deviation for the user. The scheduler schedules resource allocation for individual users according to the channel capacity average and standard deviation values, which are the statistical characteristic values, and instantaneous channel capacity fed back for the individual users, together with the found coefficients.

摘要： A method for selecting a relay mode depending on channel status of relay links in a multihop relay broadband wireless communication system and a Relay Station (RS) apparatus for supporting the method. When signals are received from a Base Station (BS) and a Mobile Station (MS), channel status values (e.g., eigenvalue, mutual information, and probability error) of relay links (BS-RS link and RS-MS link) are estimated using the received signals. The estimated channel status values are compared with a preset reference value. According to a result of the comparison, the relay mode for relaying the received signals is selected. Accordingly, the reliability of the relayed signal can be enhanced and the capacity of the signal link can be increased.
