COMMUNICATION METHOD UTILIZING UPLINK MULTIPLE INPUT MULTIPLE OUTPUT TECHNIQUE AND SYSTEM THEREOF

摘要

The present invention discloses a communication method and system using MIMO technology. The communication method includes: a network side device determines whether a UE uses a single-stream mode or a multi-stream mode as an uplink data transmission mode; and the network side device notifies the UE of indication information indicating the determined uplink data transmission mode. The communication system includes a network side device and a UE, where the network side device includes a determination module for determining whether the UE uses a single-stream mode or a multi-stream mode as an uplink data transmission mode, and a notification module for notifying the UE of indication information indicating the determined uplink data transmission mode of the UE. The communication method and system help the UE to use a specific uplink data transmission mode in combination with various factors, therefore reducing a delay of an uplink data transmission, improving an uplink data transmission speed, thereby meeting development needs of uplink high-speed data communication services of the UE.
