    摘要： A larger second bandwidth is fitted to a first transmission bandwidth by blanking PRBs at one or both edges of the larger second bandwidth. A first set of control channels is mapped to unblanked PRBs of the second bandwidth using a restricted set of physical cell identities that map only to the unblanked PRBs. A second control channel is punctured so that after it is interleaved and cyclically shifted the punctured CCEs fall on the blanked PRBs, and this second control channel is power compensated for the punctured CCEs. 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.

    摘要： 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.
