1. A method for wireless communication, comprising:

  • receiving a first orthogonal frequency division multiplexing (OFDM) symbol via a first link;

    discarding a first amount of cyclic prefix for the first OFDM symbol;

    receiving a second OFDM symbol via the first link following the first OFDM symbol;

    determining a switch time to switch from data reception on the first link to data transmission on a second link;

    determining a second amount of cyclic prefix to discard based on the switch time, the second amount of cyclic prefix being less than the first amount of cyclic prefix; and

    discarding the second amount of cyclic prefix for the second OFDM symbol.
