Claim of US Patent No. 10,117,251

1. A wireless communication apparatus comprising:a first base station providing an access point to a first communications network, the first base station being operable to communicate wirelessly with a first access terminal using a first carrier at a first frequency and having a first bandwidth;
a second base station providing an access point to a second communications network, the second base station being operable to communicate wirelessly with a second access terminal using a set of carriers at respective different frequencies within a second frequency band, wherein the second frequency band has a second bandwidth larger than the first bandwidth and the first frequency is within the second frequency band,
wherein the second base station is arranged to inhibit transmission of data by the second base station to the second access terminal using a subset of carriers having frequencies within the first bandwidth of the first frequency, and wherein the second base station comprises:
a scheduler arranged to schedule control data on the set of carriers; and
a filter arranged to remove control data scheduled to be transmitted on said subset of carriers having frequencies within the first bandwidth of the first frequency.
