  • Patent number: 11006439
    Abstract: A beam management method is performed by a UE. In one embodiment the method includes: the UE receiving a first scheduling message regarding a first scheduled downlink transmission for the UE, wherein the first scheduling message comprises pointer information pointing to an object configured in the UE. As a result of receiving the first scheduling message: the UE obtains the pointer information from the first scheduling message; the UE determines a preferred receiver configuration that is currently associated with the obtained pointer information; and the UE uses the determined preferred receiver configuration to receive the first scheduled downlink transmission.

  • Patent number: 10931429
    Abstract: One or more nodes transmit CSI-RS symbols in a set of N CSI-RS elements, each CSI-RS element in the set corresponding to at least one resource element in a time-frequency grid of resource elements. The nodes select, from the N CSI-RS elements, a first set of CSI-RS elements to be measured by a first wireless device, the first set comprising one or several of the N CSI-RS elements. The nodes also transmit, to the first wireless device, a message comprising a first K-bit indicator identifying the first set of CSI-RS elements, wherein K<N. The nodes then receive a measurement report. The first K-bit indicator is one of a predetermined set of K-bit indicators, where each member of the predetermined set of K-bit indicators uniquely corresponds to a CSI-RS element or group of CSI-RS elements from among the N CSI-RS, according to a predetermined mapping.
