LINK ADAPTATION BASED ON NEIGHBORING CELL TRANSMISSION INFORMATION

摘要

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.

1. A method for communicating with a receiver using a modulation and coding scheme (MCS), the method comprising:
determining, at a transmitter in communication with the receiver in a communications network, an interference adjustment factor that accounts for a signal interference level for a particular resource block; determining the MCS for the receiver for the particular resource block based, at least in part, on the interference adjustment factor; and communicating with the receiver using the determined MCS.
