Abstract: Techniques to reduce scheduling grants to minimize or eliminate the use of control channels, at the expense of flexibility, allow protection of the system from unnecessary retransmissions in case of interference from the primary system. Use of a single grant to allocate a set of resources across all carriers, or communication channels simplifies the system at the cost of retransmission of a grant for all carriers in the case if interference corrupts the transmission of a subset of the carriers. Thus, complementing a single grant embodiment with detection of the affected frequency carriers or victim carriers and remove such carriers from the carrier aggregation configuration allows more efficient use of the allocated spectrum.
