Abstract: A method includes receiving in a communication terminal a signal, which is transmitted in multiple links and which includes a control channel transmitted in an assigned sequence of the links. One or more candidate sequences of the links, which are likely to be the assigned sequence, are identified. For at least, one candidate sequence, a verification is made whether the candidate sequence is the assigned sequence, by re-encoding decoded bits of the candidate sequence to produce regenerated symbols and comparing the regenerated symbols to respective received symbols from which the decoded bits were decoded. The control channel is decoded from the candidate sequence in response to verifying that the candidate sequence is the assigned sequence.

Abstract: A method and arrangement for estimating the current channel quality for a data transfer in a mobile network. In a sending system entity, a channel quality estimate (CQE) associated with a data transfer to a receiving system entity in a mobile communication network is adjusted. One or more probing packets are communicated 400 between the sending system entity and the receiving system entity, each probing packet being formatted according to a predefined combination of transmission parameters. Furthermore, is a Channel State Information (CSI) report received 404 from the receiving system entity, and the CQE is adjusted 406 based on the CSI report and which probing packets have been successfully communicated. By sending a sequence of probing packets, each formatted according to a predefined combination of transmission parameters, and not waiting for each packet to be acknowledged, a fast and accurate estimation of the current channel quality is achieved.

Abstract: A method of data classification for use in a wireless communication system includes obtaining decoder metrics from a decoder. The decoder metrics correspond to data generated by the decoder. The decoder metrics include a first metric and a second metric. The method also includes classifying the data into a first category if the data fails an error detection check, into a second category if the data passes the error detection check and is determined to be unreliable, or into a third category if the data passes the error detection check and is determined to be reliable. A reliability of the data is determined based on at least one of the decoder metrics and a threshold.
