  • Patent number: 10812217
    Abstract: Systems, methods, apparatuses, and computer program products for aperiodic channel state information (CSI) reporting for enhanced carrier aggregation are provided. One method includes transmitting, by a network node, a configuration of at least two aperiodic channel state information (A-CSI) reporting modes per one or more configured downlink (DL) component carriers (CC) to at least one user equipment. The method may also include transmitting an aperiodic channel state information (A-CSI) trigger to the at least one user equipment. The transmitting of the A-CSI trigger may cause the at least one user equipment to dynamically switch between the two configured aperiodic channel state information (A-CSI) reporting modes.

  • Patent number: 10530553
    Abstract: A method comprises defining (401), in a network node (e NB), scheduled downlink carriers from a list of configured downlink carriers. The network node (e NB) defines (401) a downlink assignment index of the scheduled carrier having at least the lowest carrier index from the list of configured carriers, based on a total number of scheduled carriers. The network node (e NB) defines (401) the downlink assignment index for each other scheduled carrier having a higher carrier index from the list of configured carriers. The network node (e NB) transmits (402) to a terminal device (UE) a control message corresponding to each scheduled carrier, the control message indicating a downlink assignment scheduling a physical downlink shared channel, and comprising the defined downlink assignment index. The network node (e NB) receives (405) from the terminal device (UE), uplink control signalling indicating HARQ-ACKs related to physical downlink shared channels corresponding to the scheduled carriers.
