  • Bearer switching in reduced radio link quality conditions
    Patent number: 10749639
    Abstract: A wireless transmit receive unit (WTRU) is configured in dual connectivity with a master cell group and a secondary cell group. Uplink (UL) data is sent in an active one of the master cell group and the secondary cell group as an active UL transmission cell group. It is determined whether a UL transmission is to be switched to an alternate one of the master cell group and the secondary cell group and the UL traffic is switched from the active UL transmission cell group to the alternate cell group in response to the determination that the UL transmission is to be switched.

  • BLOCKAGE DETECTION IN MILLIMETER WAVE RADIO COMMUNICATIONS
    Publication number: 20200220670
    Abstract: Blockage detection in a wireless transmit receive unit includes performing a radio link measurement on one or more reference signals. The radio link measurement is compared to a comparing threshold and a blockage condition is indicated in response to the comparing of the radio link measurement meeting a threshold criterion on the comparing threshold.

  • TCP ENHANCEMENTS IN REDUCED RADIO LINK QUALITY CONDITIONS
    Publication number: 20180212719
    Abstract: Performance in a communications system is improved by determining whether an application executing over a data bearer is using transmission control protocol (TCP). A TCP ACK reduction request is received and at least one redundant TCP ACK is filtered out.
