    Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting uplink acknowledgement information in a wireless communication system supporting multiple carriers. A method for a terminal for transmitting uplink acknowledgement information in a wireless communication system supporting multiple carriers according to one embodiment of the present invention includes: receiving downlink control information including downlink assignment index (DAI) information representing a combination of the number of downlink control channels (n) and a priority value (n); and transmitting the uplink acknowledgement information on the basis of the number of downlink control channels (n) and the priority value (n) that the DAI information represents. Here, the DAI information includes at least one DAI value, in which varying combinations of the number of downlink control channels (n) and the priority value (n) are overlapped and mapped.

    Abstract: The invention is related to a method of transmitting data from a transmitter to a receiver in particular in a DVB-scenario. Hereby data is transmitted in consecutive bursts and each burst comprises a plurality of Multi-Protocol Encapsulation (MPE) sections and additionally Multi-Protocol Encapsulation - inter-burst-Forward Error Correction (MPE-iFEC) sections and / or Multi-Protocol Encapsulation- Forward Error Correction (MPE-FEC) sections. The content of the transmitted MPE-sections and MPE-iFEC or MPE-FEC sections is mapped into an Application Data Sub-Table (ADST) and an inter-burst-Forward Error Correction Data Sub-Table (iFDST) or Forward Error Correction Data Sub-Table (FDST) respectively. The content of the ADST and iFDST is mapped into ADT's and iFDTS's respectively as far as MPE- and MPE-iFEC sections are concerned. The decoding process is applied on a particular set of ADT and iFDT for MPE- and MPE-iFEC sections and on the ADST and FDST for MPE and MPE-FEC sections and after the decoding was performed on a particular set of ADT and iFDT the data part is copied back into ADST's.
    According to the invention the ADT and iFDT or ADST and FDST on which decoding shall be applied is divided into several subblocks before being decoded, each subblock containing one or more lines of the ADT and iFDT or ADST and FDST. Each subblock is then forwarded to the decoder, so that decoding is applied on this subblock, whereby the decoder computes the column status for each subblock, namely the total number of erroneous or missing columns in this subblock and decides whether the content of each subblock can be decoded or not based on the column status of this subblock.

    Abstract: A system and method for dectecting discontinuous transmission (DTX) frames. The inventive method includes the steps of receiving data transmitted in a pluralitz of frames (62); classifzing each of the frames (63); analyzing the classification of a number of successive frames of the received data and providing a metric with respect thereto; and determining, in response to the metric, if a frame is a discontinuous frame (66). In the illustrative embodiment, the step of classifzing includes the step of error checking the frames using a cyclic redundancz check (CRC) error checking protocol. The received frames are classified as good frames (G), erasureframes (E), or discontinuous frames (D). A numerical value is assigned toe ach of the frames based on the classification thereof. Next, the frames are filtered tp provice an output Yn=Yn-1+Xn where 'n' is a frame number, Yn is the filter output for a given frame n, Yn-1 is the filter output for a previous frame, and Xn is a stream of input frames. A threshold is set for the output Yn to facilitate the detection of discontinuous frames. That is, a detection of a discontinuous transmisson frame is indicated when a frame is classified as an 'erasure' and the filter output exceeds the threshold. On the detection of a discontinuous frame, the classification of the frame is changed from 'erasure' to 'discontinuous'. By reclassifying improperly classified erasure frames, the mobile receiver is inhibited from requesting retransmission of the frames of a change in the transmit power level. Consequently, network throughput and capacity are optimized and system power is conserved.

    Abstract: Apparatus, and an associated method, for determining whether to accept as valid a data segment, such as a radio block communicated pursuant to an EDGE communication session. A bit error rate measurer measures the bit error rate of a header part of a received radio block. The measured bit error rate is compared against a selected threshold. Results of the comparison are determinative of whether the radio block is accepted as valid or rejected as corrupted.
