A communication device and method to detect a sidelink identification from a second device for device to device, or sidelink, communication by performing a series of correlations using the demodulation reference signal and a set of demodulation reference templates stored in the memory component of the communication device. The communication device is further configured to reduce the computational complexity of the correlation procedure in the sidelink identification detection process by reducing the number of templates that need to be correlated with the demodulation reference signal and by reducing the number of complex-value multiplications of the correlation process.

Device and method for device to device communication

The present disclosure relates to a method for blind decoding a signal in a decoder of a mobile device. The method comprises receiving a channel coded signal; testing a plurality of hypotheses for the decoder that are not related to channel decoding by decoding the channel coded signal to generate a hypothesis specific decoded, channel coded signal and correlating a local channel coded reference sequence against a presumed corresponding section of the hypothesis specific decoded, channel coded signal for each of the plurality of hypotheses to generate a plurality of test results. The method further comprises determining a best hypothesis based on the plurality of test results and channel decoding a hypothesis specific decoded, channel coded signal for the best hypothesis to generate a channel decoded signal.

Method and related mobile device for fast blind decoding

The disclosure relates to a decoding device, comprising: a receiver configured to provide a sequence of information bits comprising context redundancy information, wherein the sequence of information bits is encoded based on a predefined channel code; a trellis generation logic configured to generate a plurality of trellis states based on the sequence of information bits and the channel code; a trellis reduction logic configured to reduce the plurality of trellis states by at least one trellis state based on the context redundancy information; and a decoder configured to decode the sequence of information bits by using a metric based on the reduced number of trellis states.
