A method and an arrangement for radio communication

摘要

There is provided a method and an arrangement for flexible coexistence of several radio communication systems on a common radio frequency band (R). The radio frequency band (R) having a larger bandwidth than the communication frequency band (BC1; BC2) of the several radio communication systems. Prior to the start of a radio communication, the radio frequency band (R) is scanned by a radio transceiver unit (30; 34; 40) of a system for the detection of the presence of interference. The transceiver units (30; 34; 40) are arranged to establish communication over any idle part of the radio frequency band (R) comprising said communication frequency band (BC1; BC2), thereby avoiding the need for frequency or channel planning. The invention can be used in Personal Communication Systems (PCS) or Cordless Terminal Mobility (CTM) services and Radio in the Local Loop (RLL) applications.
