METHOD AND TERMINAL FOR TRANSPORT BLOCK RETRANSMISSION TRIGGERED BY PHYSICAL HYBRID AUTOMATIC REPEAT REQUEST (HARQ) INDICATOR CHANNEL

摘要

The present invention discloses a method and terminal for transport block retransmission triggered by a physical hybrid automatic repeat request (HARQ) indicator channel. The retransmission method includes: the terminal precodes the transport blocks to be retransmitted with a defined precoding matrix or vector, wherein the precoding matrix or vector is a precoding matrix or vector predefined according to the precoding matrix or vector indicated by the latest scheduling signaling, or the precoding matrix or vector is selected from a codebook or a precoding matrix set for retransmission; the terminal retransmits the precoded transport blocks. With the technical solutions of the present invention, the transport blocks can be retransmitted effectively in the premise of saving signaling cost.
