Asynchronous multi-point transmission schemes

Abstract

Asynchronous multi-point transmission techniques for MIMO networks are provided. An example method comprises receiving, by a device comprising a processor, a first data signal from a first TP device of a wireless communication network, wherein the first data signal comprises first code-word information generated based on a data. The method further comprises receiving, by the device, a second data signal from a second TP device of the wireless communication network, wherein the second data signal comprises second code-word generated based on the data, wherein the first code-word information and the second-code word information are different, and wherein the first TP device and the second TP device are geographically separated by a threshold distance. The device can further process the first data signal and the second data signal to generate a unified data signal representative of the data.
