    摘要： A method in a base station for detecting a HARQ-ACK codeword comprised in a signal received from a UE is provided. The base station knows HARQ-ACK codewords being possible to detect. The base station receives (401) a signal from the UE comprising a modulation symbol. The base station estimates (402) a SNR value for the received signal, and calculates (403) soft values for the modulation symbol. When the SNR value is lower than a predetermined threshold value and when the modulation symbol of the received signal comprises more than two bits per modulation symbol, the base station uses a first mode. The first mode comprises correlating (405) only the two first calculated soft values for the modulation symbol with the one or more known possible HARQ-ACK codewords. In other cases, i.e. when the first mode is not used, the base station uses a second mode. The second mode comprises correlating (408) all calculated soft values for the modulation symbol with the known possible HARQ-ACK codewords.

    摘要： A basic idea is to determine (S1) occurrence of a glitch caused by operation of the AGC mechanism, identify (S2) those modulation symbols in a digitized version of the received signal that are affected by the glitch, each modulation symbol represented by a number of bits in combination, and then reduce (S3), for each of the identified modulation symbols, the contribution in representing the identified modulation symbol as provided by at least a subset of the bits of the modulation symbol. In this way, the adverse effects of the glitch can be effectively mitigated and subsequent detection of the desired signal can be significantly improved. This also means that the link performance will be significantly improved.

    摘要： There is disclosed a method for estimating a frequency offset between a mobile communication terminal and a network node. The method is based on processing, by means of a matched filter, a preamble sequence for random access received on a physical random access channel, PRACH. Thus the method is preferably applied in the Evolved Universal Terrestrial Radio Access (E-UTRA) network. In the matched filtered preamble sequence two peaks are determined and the frequency offset is based on a ratio of the two peaks. A corresponding network node, computer program and computer program product are also presented. The network node is preferably performed in a network node of the type eNodeB, E-UTRAN NodeB, also known as Evolved NodeB.

    摘要： A method of determining a set of Zero Correlation Zone (ZCZ) lengths, comprises: determining the length of a root sequence, and selecting such a set of ZCZ lengths that, for any cell radius, the maximum number of preambles obtained from a ZCZ length which is selected from the selected set of ZCZ lengths is closest to the maximum number of preambles determined from a ZCZ length which is selected from the set of all integers, wherein the maximum number of preambles is determined from the length of the root sequence and a ZCZ length selected. This disclosure provides a technical solution for selecting a better limited set of ZCZ lengths by which signaling overload is reduced.

    摘要： The present invention relates to a method for allocating communication resources in a multi-user cellular communication system, wherein communication resources are divided in time periods and frequency sub-bands, wherein part of the communication resources are used for frequency-localized communication channels, and part of the communication resources are used for frequency distributed channels. The method further comprises the steps of classifying part of the frequency sub-bands as frequency sub-bands carrying frequency-distributed channels, classifying the remaining part of the frequency sub-bands as frequency sub-bands carrying frequency-localized channels. The present invention also relates to a system, a transmitter and a communication system.
