1. A method for allocating communications resources in a radio communications system having a plurality of communications resources for at least one receiver and transmitter to communicate over where the communications resources have signal levels which vary due to a multipath environment resulting in periods of poor communication quality over at least one particular communications resource, the method for allocating communications resources comprising the steps of:

  • measuring at a first receiver a parameter indicative of a quality of communications between the first receiver and a first transmitter over a first communications resource;

    determining whether to allocate a second communications resource to the first receiver and the first transmitter based on the measured parameter;

    upon determining that a second communications resource should be allocated to the first receiver and the first transmitter,allocating the first communications resource to a second receiver and a second transmitter; and

    allocating a communications resource that was being used by the second receiver and second transmitter to the first receiver and the first transmitter as the second communications resource, thereby effectively exchanging communications resources of at least two receiver and transmitter pairs in order to effectively reduce periods of poor communications quality due to multipath fading between the first receiver and the first transmitter.
