摘要： A base station node communicates over a radio interface with a wireless terminal. The base station node comprises a controller which, upon basis of channel feedback received from the wireless terminal, is configured to make a precoding codebook bitmap decision regarding a precoding codebook bitmap affecting transmissions between the base station and the wireless terminal. The base station is further configured to communicate the precoding codebook bitmap decision so that the precoding codebook bitmap decision may be implemented by the wireless terminal. In example embodiments and modes the base station sends the precoding codebook bitmap decision using a bitmap decision signal to a radio network controller.

摘要： The present invention relates to a method for supporting network assistance interference cancellation at a first wireless device served by a first radio network node of a wireless communication network. A transmission of a second radio network node of the wireless communication network directed to a second wireless device interferes with a transmission of the first radio network node directed to the first wireless device. The method is performed in the second radio network node and comprises determining (610) whether to transmit network assistance information related to the transmission of the second radio network node to support interference cancellation at the first wireless device, and transmitting (620) the network assistance information to the first wireless device based on the determining.

摘要： A method by a network node in a communications system includes determining a codebook subset restriction indicating a reduced set of precoding matrices out of an original set of precoding matrices in an original codebook. The full set of Precoding Matrix Indicator, PMI, bits is used to identify the original set of precoding matrices in the original codebook. The method includes determining a reduced set of Precoding Matrix Indicator, PMI, bits for use in a feedback channel based on a number of entries in the reduced set of precoding matrices. The reduced set of PMI bits has fewer bits than the full set of PMI bits. Related user equipments, methods by user equipments and network nodes are disclosed.

摘要： There is provided a method performed by a User Equipment, UE, for encoding Hybrid Automatic Repeat Request, HARQ, Acknowledgements, ACK/NACK, in a multi-antenna wireless communications system. The method comprises the step (S1) of bundling, also referred to as co-representing, a HARQ-ACK/NACK to be sent in response for a transport block of information with a HARQ-ACK/NACK to be sent in response for another transport block of information, when more than two transport blocks of information are used. The method also comprises the step (S2) of encoding the bundled HARQ-ACK/NACK information.
