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 ensures that the UEs are able to make use of all the available reference signals that can be used in a cell for performing UE measurements, estimations or demodulations. That is achieved by indicating on a downlink common or shared channel, the MIMO mode settings associated with a specific network node. The indicated MIMO mode settings explicitly or implicitly indicate available common reference signals and/or dedicated reference signals to be used for said UE measurements, estimations or demodulations, which implies that measurements, estimations or demodulations can be performed based on said received indication.

摘要： A mechanism for increasing a sectorization order in a first sector of an antenna array. The object is achieved by a method in a network node. The network node and antenna array are comprised in a wireless communication system. The antenna array is deployed with a first sectorization. The network node comprises a first number of signal connections. Each signal connection is adapted to transmit and receive signals. The method comprises the step of splitting the first number of connections into a number of groups. Each one of the respective connection groups corresponds to one respective virtual sector resulting in a number of virtual sectors. The method further comprises the step of mapping the number of virtual sectors to the first sector, such that the first sector is split into the number of virtual sectors.

摘要： A first base station (14) in a wireless communication system (10) operating according to a synchronised time division scheme detects interference of uplink communication, determines the delay of the interference in relation to an own communication structure (CS1), detects aerial interface identifying data of the source of interference identifying a further base station and sends an indication of the further base station interfering uplink communication to the interference handling node (22). The indication is accompanied by identification data comprising aerial interface identifying data of the further base station and distance data determining the distance (D1) between the first and the further base station. The interference handling node (37) receives the indication with accompanying identification data, investigates the identification data in order to determine the identity of a candidate for the further base station and orders the candidate base station to perform an interference limitation activity.
