1. A method comprising:

  • receiving, at a receiver, a first input within a first frequency range centered at a first center frequency during a first time period, the first input comprising a first signal and a second signal, wherein the first signal is encoded using a first radio technology and the second signal is encoded using a second radio technology;

    separating the first input into the first signal and the second signal;

    transmitting a first message to a source of the first signal and the second signal, the first message indicative of a second time period during which the source is not to transmit to the receiver;

    recentering the receiver to receive a second input within a second frequency range centered at a second center frequency, wherein recentering the receiver is based on a set of criteria; and

    wherein the set of criteria comprises a first criterion, the first criterion corresponding to whether a signal-to-interference-plus-noise ratio (SINR) of the first signal received within the first frequency range is above a threshold SINR, a SINR of the second signal received within the first frequency range is above the threshold SINR, or a combination thereof;

    transmitting a second message to the source, the second message indicative of a third time period during which the source is to transmit to the receiver; and

    receiving, at the receiver from the source, the second input within the second frequency range during the third time period, wherein the third time period is after the second time period.
