摘要： The methods and apparatus disclosed herein processes reference signals in an antenna diversity system, e.g., where both the transmitting and receiving devices use multiple antennas. The solution presented herein process reference signals at the transmitting device in such a way to enable the receiving device to efficiently and accurately estimate the covariance matrix associated with data transmitted using transmitter diversity. This is achieved by processing the reference signals used for the covariance estimation and the data signals in the same way, e.g., by precoding data and reference signal portions of one or more signals using the same coding scheme.

摘要： In certain embodiments, a method for use in a network node comprises sending a control information message to at least one wireless device that is in idle mode. The message comprises a mapping that maps a quasi co-location (QCL) assumption to a multicast transmission or multicast channel. For example, in certain embodiments, the multicast transmission or multicast channel is associated with a temporary multicast group indicator (TMGI), and the mapping maps the QCL assumption to the TMGI. The control information message causes the at least one wireless device to use the QCL assumption to decode the multicast transmission or multicast channel while in idle mode.

摘要： A method in a receiver node (110, 115) is disclosed. The method comprises converting (604) a received time-domain signal (305, 405) to a frequency-domain signal, and obtaining (608), for the frequency-domain signal, an estimate of a frequency offset between a particular transmitter of one or more transmitters of interest and a receiver of the receiver node. The method comprises obtaining (612) a frequency compensated signal by applying a first frequency offset to compensate for the estimated frequency offset, and obtaining (616) a first channel estimation from the frequency compensated signal. The method comprises obtaining (620) a second channel estimation from the first channel estimation by applying a second frequency offset to the estimated channel, wherein the second frequency offset is the opposite of the first frequency offset.
