Method and device for switching from dual stream to single stream in uplink MIMO mode |
摘要 |
Embodiments of the present disclosure provide a method for switching from a dual stream to a single stream in an uplink MIMO mode. The method includes: sending a scheduling command with a value of absolute grant being zero_grant to a secondary data stream; and after a preset time since the scheduling command takes effect, sending a switching command that instructs a terminal to switch from an uplink MIMO dual stream to an uplink MIMO single stream. Hence, the embodiments of the present disclosure help to reduce data loss, and meanwhile, to simplify the HARQ design for switching from an uplink MIMO dual stream to an uplink MIMO single stream. |
