Systems and methods for supporting irregular bandwidth channels
User equipment that is capable of filtering for an irregular bandwidth of an allocated channel may send an indication of this capability to a network, which may then configure the channel to a next higher standard channel size, enabling the user equipment to filter this larger channel bandwidth to the irregular bandwidth. User equipment that is not capable of filtering for the irregular bandwidth may send an indication that it does not have this capability to the network, which may then configure the channel to a next lower standard channel size, thus avoiding the need for the user equipment to filter a larger channel bandwidth to the irregular bandwidth. In cases where the network detects that a blocking signal is not present that may interfere with the allocated channel, the network may configure the channel to the next higher standard channel size.
