Using scheduling information to adapt transmission block sizing

摘要

The present invention discloses a scheduling information transmission method, device, and communications system. The method includes: generating a channel attribute parameter and a serving grant SG, where the channel attribute parameter and the SG are used for data scheduling of uplink multiple input multiple output MIMO; and delivering the channel attribute parameter and the SG to a user equipment UE through a target channel, where the channel attribute parameter is used by the terminal to determine a primary-stream enhanced dedicated channel transport format combination indicator E-TFCI and a secondary-stream E-TFCI. In the scheduling information transmission method, device, and communications system that are provided in embodiments of the present invention, the determined E-TFCIs can better adapt to different channel conditions, which improves data transmission performance.
