摘要： A method for wirelessly transmitting data with a transmitter using a plurality of transmission, layers includes estimating a number of data vector symbols (124) to be allocated to one or more user data codewords (122) during the subframe arid determining a number of bits in the one or more user data codewords (122), The method also includes calculating a nominal number of control vector symbols (124) to allocate to control information based., at least in part, on the estimated number of data vector symbols (124) and the determined number of bits in the one or more user data codewords (122). Additionally, the method includes determining an offset value based, at least in part, on a number of layers over which a transmitter (100) will be transmitting during the subframe and calculating a final number of control vector symbols (124) by multiplying the nominal number of control vector symbols (124) and the offset value. The method also includes mapping one or more control codewords (120) to the final number of control vector symbols (124) and transmitting the user data vector symbols and the control vector symbols over the plurality of transmission layers during the subframe.

The feedback data is indicative of channel properties of a data channel (120) for sending data from the second node (111) to the first node (110).

摘要： The present invention relates to a solution for taking into account that the interference, which each of the transmission resource elements is affected by, may differ between the different transmission resource elements when determining an interference estimate by determining a mixed interference estimate, e.g. based on both reference symbols and data symbols. Furthermore, signalling from the network is also introduced which makes it possible to control what the mixed interference estimate should be based on.

摘要： The invention relates to devices and methods for signalling control information associated with transmission of data over a wireless channel. A second communication device receives (S2) data from a first communication device, wherein the data comprises an indication of recommended precoders and a recommendation of a first transmission rank to possibly use during transmission.

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： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node (400) and a receiving node (402). When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.

摘要： Data is transmitted over multiple input multiple output (MIMO) channels. Plural bit streams are modulated into multiple data symbol vectors. Each vector has a transmission rank with one vector for each MIMO channel. Transmission rank is the number of elements in a data symbol vector corresponding to the number of data streams being transmitted in parallel over each MIMO channel. The multiple data symbol vectors are preceded into multiple precoded symbol vectors using a plurality of precoder cycling sets, one set for each transmission rank including multiple different precoders. The precoders in each precoder cycling set are well-separated with respect to a plurality of distance measures. The precoding includes precoding each data symbol vector of a transmission rank with a precoder belonging to the precoder cycling set of that transmission rank. The precoded symbol vectors are then transmitted over the MIMO channels.
