  • Patent number: 10779323
    Abstract: A method in a wireless device for performing random access to a network node. The method comprises receiving a set of downlink beam-specific reference signals, BRS, from the network node, and determining a preferred BRS based on the received signal power for each BRS. The method also comprises selecting, based on the preferred BRS, a random-access resource to be used for transmitting a random-access attempt to the network node, as well as using the selected random-access resource when transmitting a random-access attempt to the network node, whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions.

  • Patent number: 10700821
    Abstract: Systems and methods are disclosed herein that allow a radio access node to command a wireless device to clear parts of a soft buffer for a Hybrid Automatic Repeat Request (HARQ) process. In some embodiments, a method for a wireless device in a wireless communications system comprises receiving control information comprising information pertaining to whether the wireless device should partially clear a soft buffer for a HARQ process, deciding whether to partially clear the soft buffer for the HARQ process based on the information comprised in the control information, and partially clearing the soft buffer for the HARQ process upon deciding to partially clear the soft buffer for the HARQ process. In this manner, corrupted soft information can be cleared from the soft buffer while retaining uncorrupted soft information in the soft buffer.
