The controller is responsive to the radio access scheduling information containing an indication of a time when during a scheduling interval reception is blocked for a receiver of the apparatus, due at least in part to simultaneously scheduled operation of a transmitter, to send information to the error correction function for marking as erased any symbols received during a time that the reception is indicated to be blocked. The exemplary embodiments of this invention may be realized at least in part in a software defined radio platform that includes the multiradio controller and a plurality of radio access units. ## Claims ### Claim 1 An apparatus, comprising: a controller configured to provide radio access scheduling services for a plurality of radio access units in response to scheduling requests received from the plurality of radio access units, said controller configurable with a scheduler that is configured to schedule radio access in response to received scheduling requests and to send radio access scheduling information to the plurality of radio access units;
