Abstract: The present disclosure provides a fine-grained link adaptation mechanism that allows for link adaptation at a resource block granularity. To this end, the fine-grained link adaptation mechanism can determine the effective signal-to-interference-plus-noise ratio for individual user equipment in a particular cell at the resource block granularity. This way, the transmitter can use the effective signal-to-interference-plus-noise ratio to adapt the modulation and coding scheme at the resource block granularity. The fine-grained link adaptation mechanism can be introduced to a long term evolution (LTE) network without substantial redesign of the LTE network.

Abstract translation: 本公开提供了一种细粒度的链路自适应机制，其允许以资源块粒度的链路适配。 为此，细粒度的链路自适应机制可以以资源块粒度来确定特定小区中的各个用户设备的有效信号与干扰加噪声比。 这样，发射机可以利用有效的信号与干扰加噪声比来调整和编码方案在资源块的粒度上。 可以将细粒度的链路适配机制引入到长期演进（LTE）网络中，而不需要对LTE网络进行大量重新设计。
