Abstract: The present invention relates to dynamic spectrum refarming with multiple carriers. At a first communication system of a first radio access technology, a request is received in a first signaling message from a second communication system of a second radio access technology, the request including information on availability of spectrum blocks shared between the first and second communication systems. The availability of the spectrum blocks may have been determined based on a load of the second communication system. The first communication system performs carrier aggregation mechanisms based on the information with respect to the spectrum blocks, and may transmit a response to the request in a second signaling message to the second communication system, the response including an acknowledgment of an activation/deactivation of at least one additional carrier and/or a corresponding carrier aggregation.

The first set and the second control channels are assigned in view of the puncturing and blanked PRBs, an IFFT for the larger second bandwidth is performed on a signal using zeros at the blanked PRBs, the signal is filtered to the first bandwidth and transmitted over a bandwidth not to exceed the first bandwidth.

Abstract: A data sequence consisting of K information bits that has been encoded with the help of a binary convolution code is decoded using a MaxLogMAP algorithm. In a first calculation operation, metric values are calculated accurately in a forwards and backwards direction in a trellis diagram and only some of the values are stored in a memory as interpolation points for an additional calculation operation. The additional calculation operation uses the interpolation points to accurately calculate the metric values that lie between the interpolation points of the first calculation operation. Soft output values are accurately determined for decoding after n operations.
