Abstract: Techniques for detecting discontinuous transmission (DTX) are disclosed. In an example method, given a sequence of bits that is known by a wireless receiver to be included in transmission bursts targeted to the wireless receiver and given a series of received signal samples corresponding to an expected transmission burst for the wireless receiver, the wireless receiver estimates a channel response and a location for the sequence within the series. The wireless receiver generates a plurality of bit estimates from the subset of received signal samples, based on the estimated channel response, compares the bit estimates to bits in the sequence of bits, and determines whether a valid burst for the wireless receiver is present, based on said comparing. The disclosed techniques are particularly suitable for use in detecting DTX in VAMOS scenarios.

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 wireless communication unit comprises a receiver for receiving information from a remote transmitter unit. The receiver comprises a demodulator for demodulating received data packets operably coupled to a decoder arranged to perform a cyclic redundancy check (CRC) on the demodulated received data packets and perform multi-protocol encapsulated (MPE) decoding thereon.

Abstract: When errors occur in a packet received from a satellite terminal device, a modulation and coding (MODCOD) value is calculated according to a result of the detection, and a calculated MODCOD value is transmitted to the satellite terminal device, so that packet loss is reduced based on the yield of actual traffic when the satellite terminal device transmits a return link packet. An occurrence of a packet error is detected by generating a first return link packet by sequentially assembling the plurality of return link packets from the satellite terminal device and performing a comparison analysis by comparing the first return link packet with a newly received second return link packet.
