Generally, the described techniques provide for a base station transmitting an indication of a set of one or more available channels to a user equipment (UE). The base station may transmit to the UE a first downlink burst using a first channel and a first frame period. In some cases, the base station may detect interference associated with the first downlink burst, for example, by performing a listen-before-talk (LBT) procedure or through an interference management resources (IMR) procedure in which the base station transmits reference signal signals to the UE that the UE may use to return a report on measured interference. If the base station detects interference, the base station may transmit to the UE an instruction to switch to a second channel and a second frame period, where the second channel may be selected from the set of one or more available channels.
