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： The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple- Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling. SU-MIMO mode signaling which is redundant, i.e. not needed, for MU- MIMO mode signaling is identified. Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.

摘要： The available transmission resources on a downlink-shared channel are divided into resource blocks, each resource block comprising a predetermined number of sub-carriers during a predetermined time period. The resource blocks are subdivided into localized resource blocks and distributed resource blocks. A user requiring sufficient resources can be allocated a plurality of said localized resource blocks. A user who would require only a small number of said localized resource blocks can instead be allocated subunits of a plurality of said distributed resource blocks.

摘要： A method in a receiving node for sending an acknowledgement/not acknowledgement 'ACK/NACK' feedback report of received data units over a radio link is provided. When the receiving node have received (301 ) data units in a number of subframes over a first radio link from a sending node, it creates (302) an ACK/NACK feedback report. The report is compressed such that it comprises one single ACK/NACK feedback relating to the data units in the number of received subframes, and the report comprises an indicator indicating said number of received subframes. The receiving node then transmits (303) the created ACK/NACK feedback report to the sending node over a second radio link. The feedback report renders it feasible for the sending node to decide whether a retransmission of any subframe is required or not based on a comparison of the reported number of received subframes with the known transmitted number of subframes per frame, together with the compressed ACK/NACK feedback report.
