1. A method for uplink data transmission in a wireless communication system including a first wireless communication node and a second wireless communication node both serve a terminal, wherein the first wireless communication node is a downlink serving node of the terminal, and the second wireless communication node is an uplink serving node of the terminal, the method comprising:

  • determining, by a first wireless communication node, whether a terminal is within downlink coverage of the second wireless communication node; and

    when the first wireless communication node determines that the terminal is not within the downlink coverage of the second wireless communication node;

    instructing, by the first wireless communication node, the terminal to use a non-feedback mode in which the terminal does not retransmit to the second wireless communication node, uplink data that has been sent; and

    /orinstructing, by the first wireless communication node, the second wireless communication node to use a non-feedback mode in which the second wireless does not receive, on a time-frequency resource allocated to the terminal, uplink data retransmitted from the terminal.
