摘要： A method in a terminal for providing an ACK/NAK message to a base station is provided. The terminal counts the number of assigned downlink subframes detected from the base station resulting in k. The terminal then establishes whether each of a number of transport blocks comprised in the counted k downlink subframes is correctly received or not. In the case when each one of the transport blocks, comprised in the k downlink subframes is estimated as correctly received the terminal provides to the base station an encoded ACK message for the k subframes, which comprises k, the number of subframes.

摘要： Downlink control information (DCI) extensions to support 3GPP Rel-10 functionalities comprise minimal extensions of DCI format 2B. In some embodiments, only two extra bits (20) are introduced to signal rank up to eight, by reusing the Scrambling Identity bit (16) while at the same time supporting different MU-MIMO dimensioning for the important cases of rank-1 and rank-2. This new DCI format can potentially support not only single cell downlink transmission but also some other Rel-10 functionalities, e.g. CoMP or relaying/HetNet.

摘要： An object of the present invention is to provide a mechanism for improving the detection of missed DL assignment. A method in a base station (110) for sending a data packet to a mobile terminal (120) is provided. The base station (110) uses a current bundling window for transmitting data packets in subframes of a radio channel. The bundling window comprises a number of data packets, already transmitted or to be transmitted to the mobile terminal (120). The data packets are to be confirmed by the mobile terminal (120). In a first subframe, the base station signals to the mobile terminal (120), a first downlink assignment of a first data packet of the bundling window. The downlink assignment comprises knowledge about a minimum total number of data packets within the bundling window that are scheduled to be transmitted to the mobile terminal (120).
