LTE SCHEDULING

摘要

A method to be carried out in a wireless communication network comprising at least one base station associated to a corresponding area for transmitting/receiving data to/from corresponding user terminals located within said area is disclosed. The method comprises generating a user-rate matrix for each base station. Each element of the user-rate matrix provides a corresponding score, in terms of achievable rate, to a user terminal or to a group of user terminals located within the corresponding area when a transmission is made to/from said user terminal or said group of user terminals, respectively, from/to the base station by employing a selected transmission mode among a set of predetermined transmission modes. The method further comprises processing the elements of the user-rate matrix in order to create a scheduling list where the elements are sorted by a decreasing score, and associating to each user terminal a corresponding selected transmission mode based on the scheduling list for the transmission/reception of data to/from the base station. Said set of predetermined transmission modes includes at least a spatial multiplexing transmission mode, a transmit diversity transmission mode and a multi-user multiple-input multiple-output transmission mode.
