    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: Disclosed is a method for deciding a signal detection order in a mobile communication system that supports an adaptive modulation technology. The detection order that maximizes a channel, in which a product of the minimum symbol distance for each modulation rate and the effective SINR becomes minimum, maximum is selected by obtaining the effective SINR and performing a bit allocation with respect to the detection orders of each detection order, and thus an average error probability can be minimized. In the case in which the number of antennas is increased, the detection orders of all the possible cases are not considered, but the detection order that maximizes the channel, in which the product of the minimum symbol distance for each modulation rate and the effective SINR becomes minimum, is selected with respect to a forward ordering and a reverse ordering.
