摘要： A method for wirelessly transmitting user data and at least a first type of control information using a plurality of transmission layers including encoding bits of a first type of control information to form one or more control codewords and encoding bits of user data to form one or more user data codewords. The method also includes generating a plurality of vector symbols based on the control codewords and the user data codewords. Each vector symbol includes a plurality of modulation symbols that are each associated with a transmission layer over which the associated modulation symbol will be transmitted. Generating the plurality of vector symbols includes interleaving bits of the one or more control codewords and bits of the one or more user data codewords so that the first type of control information is carried in modulation symbols associated with the same transmission layers in all the vector symbols transmitted during the subframe that carry the first type of control information. The method also includes transmitting the plurality of vector symbols to a receiver over a plurality of transmission layers.

摘要： Embodiments are disclosed which improve the accuracy of measurement quantities obtained based on filtered measurements, by enabling filter memory reset events triggered by specific configuration and/or reconfiguration commands. According to some embodiments, a method for obtaining a measurement quantity is provided. The measurement quantity is based on a filtered reference signal (RS) measurement value. The method is executed in a wireless device, e.g. a user equipment (UE). According to the method, the wireless device receives (1410) a filter reset indication. In response to the indication, the wireless device resets (1420) one or more RS measurement filters. The wireless device then obtains (1430) a new filtered RS measurement value, and obtains (1440) the measurement quantity based on the new filtered RS measurement value.

摘要： A method for wirelessly transmitting data and control information using a plurality of transmission layers includes determining a number of bits in one or more user data codewords to be transmitted during a subframe and calculating a number of control vector symbols to allocate to control information during the subframe. The number of control vector symbols is calculated based at least in part on the number of bits in the one or more user data codewords to be transmitted during the subframe and an estimate of the number of vector symbols onto which the one or more user data codewords will be mapped. The estimate of the number of vector symbols depends, at least in part, on the number of control vector symbols to be allocated to control information. The method also includes mapping one or more control codewords to the calculated number of control vector symbols and transmitting vector symbols carrying the one or more user data codewords and the one or more control codewords over the plurality of transmission layers during the subframe.

摘要： In a transmitter or transceiver, signals can be precoded by multiplying symbol vectors with various matrices. For example, symbol vectors can be multiplied with a first column subset of unitary matrix which spreads symbols in the symbol vectors across virtual transmit antennas, a second diagonal matrix which changes a phase of the virtual transmit antennas, and a third precoding matrix which distributes the transmission across the transmit antennas.

摘要： A system and method for improving the link adaptation in a wireless communication system is disclosed. User Equipment (UE) forms an interference hypothesis by amending a measured interference and noise by artificially injecting, to the measured interference and noise, interference corresponding to at least one emulated interfering isotropic signal that is virtually transmitted over an associated estimated effective channel. The UE further determines at least one channel state information (CSI) report based on the interference hypothesis, and transmits the CSI report to the network.

摘要： Embodiments herein relate to a method in a radio base station (12) for transforming a data transmission signal in a radio communications network. The radio base station (12) is connected to an active antenna array of a first number of active transmitting antennas, which each active transmitting antenna comprises sub elements. The radio base station (12) comprises a precoder codebook comprising precoders for transmitting signals in a diversified manner for a second number of antenna ports. The radio base station serves a user equipment in the radio communications network. The radio base station (12) precodes the data transmission signal with a precoder selected from the precoder codebook.
