Abstract
Wireless transceiver apparatus for operating in a part of the RF spectrum which is shared with a co-located second wireless transceiver apparatus. The first wireless transceiver apparatus includes, a wireless transceiver unit; an arbitration interface for interfacing with an arbitration entity which arbitrates access to the shared part of the RF spectrum between the first wireless transceiver apparatus and the second wireless transceiver apparatus; wherein the arbitration interface is adapted to signal time periods when the wireless transceiver unit is operational, or requests to be operational; and wherein the arbitration interface is adapted to signal data about and commands to the arbitration entity during other time periods. An enhanced arbitration entity is adapted to automatically detect and switch between two modes of interference reduction, e.g. a first interference reduction means such as AFR, a second interference reduction means such as PTA. The arbitration entity gets the information of the first wireless transceiver via the arbitration interface.
