  • Radio node and method therein for determining precoders
    Patent number: 10868599
    Abstract: A method performed by a first radio node for determining one or more precoders for beamforming of reference signals is provided. The reference signals relate to Channel State Information, CSI, of a forward link channel from the first radio node to a second radio node. The first radio node receives (201) reverse link reference signals from the second radio node and estimates (202) a first quality value of the forward link channel based on the received reverse link reference signal. The first radio node then determines (203) one or more first precoders of respective one or more first ranks based on the reverse link reference signal and the estimated first quality value. When the one or more first precoders have been determined, the first radio node triggers (204) a first transmission of one or more first forward link reference signals to the second radio node. The one or more first forward link reference signals are beamformed according to the determined respective one or more first precoders.

  • Method and apparatus for providing channel state information status by a transceiver
    Patent number: 10804992
    Abstract: In one aspect of this disclosure, a transceiver obtains and transmits a CSI status indicator. In one example, the CSI status indicator indicates that previously reported CSI is outdated and/or that a new CSI report is available at the transceiver. In some embodiments, the transceiver generates or transmits the CSI status indicator according to a particular configuration, which may be set by a supporting wireless communication network. The configuration may include criteria on when to transmit the CSI status indicator, such as configuration criteria indicating that the transceiver should transmit the CSI status indicator responsive to completing its determination of a full-dimension beamforming matrix to be used for controlling beamforming towards the transceiver. The transceiver comprises, for example, a wireless device operating within a wireless communication network and the CSI status indicator corresponds to the status of downlink CSI.

  • Dynamic precoding of shared reference signals
    Patent number: 10785007
    Abstract: A receiver apparatus receives a terminal-specific demodulation reference signal having a rank k and estimates an effective multi-layer channel response, using the received terminal-specific demodulation reference signal. The receiver demodulates first data symbols from first time-frequency resource elements, using the estimate of the effective multi-layer channel response and using a first symbols-to-virtual-antenna mapping matrix M to obtain nc modulation symbols from each of the first time-frequency resource elements, wherein nc>1 and wherein the first symbol-to-transmit-layer mapping matrix M has dimensions k by nc. The first data symbols are decoded to obtain downlink control information assigning second time-frequency resource elements to the receiver.
