Method and apparatus for packet retransmission

Example embodiments of the present invention provide a method and apparatus for packet retransmission. The method comprises binding a plurality of consecutive packets of the device to obtain a bound packet. The method further comprises transmitting the bound packet for multiple times in at least one of a time domain and a frequency domain, wherein at least one of a time interval and a frequency interval is present between every two consecutive transmissions. Through binding a plurality of consecutive packets into one bound packet and transmitting the bound packet for multiple times at a time interval and/or a frequency domain interval in the time domain and/or the frequency domain, upon reception of the packet, not only the gain obtained by joint channel estimation across a plurality of subframes is maintained, but also the time diversity gain and the frequency domain diversity gain may also be obtained for each of the plurality of consecutive packets, thereby enhancing link performance.
