Abstract: A method is provided for performing downlink scheduling in Long Term Evolution-Advanced networks. The method includes assigning resource blocks and transmission modes to users such that (i) each of the users that is assigned at least one of the resource blocks is assigned only one transmission mode chosen from a finite set of transmission modes, (ii) a sum of normalized costs across all of the resource blocks that are assigned to the users is less than unity. The method further includes incorporating a resource block and transmission mode assignment for a user into downlink scheduler of a base station to cause the downlink scheduler to perform downlink scheduling in accordance with the resource block and transmission mode assignment.

Abstract translation: 提供了一种用于在长期演进 - 高级网络中执行下行链路调度的方法。 该方法包括向用户分配资源块和传输模式，使得（i）被分配至少一个资源块的每个用户只分配从有限传输模式集合中选择的一种传输模式，（ii）总和 分配给用户的所有资源块的归一化成本小于1。 该方法还包括将用户的资源块和传输模式分配合并到基站的下行链路调度器中，以使下行链路调度器根据资源块和传输模式分配来执行下行链路调度。

Abstract: A method is provided for optimizing energy efficiency over an energy-harvesting Long Term Evolution cellular network. The method includes assigning (a) resource blocks, (b) transmission modes, and (c) bit loadings on the resource blocks to a set of users such that (i) the assigned resource blocks satisfy a system of linear ascending inequality constraints, and (ii) respective sums of the bit loadings for each of the users do not exceed respective queue sizes pertaining to the each of the users. The method further includes incorporating a resource block and transmission mode assignment for a user into downlink scheduler of a base station to cause the downlink scheduler to perform downlink scheduling in accordance with the resource block and transmission mode assignment.
