  • METHOD AND APPARATUS FOR MANAGING COMMUNICATION WHEN A SERVING BEAM BECOMES INVALID IN A WIRELESS COMMUNICATION SYSTEM
    Publication number: 20180006770
    Abstract: A method for a wireless communications system is disclosed. In one example, user equipment (UE) maintains at least one serving beam, and uses a serving beam to perform an uplink (UL) transmission of data. The data is stored in an uplink hybrid automatic repeat request (UL HARQ) buffer. When there is a failure to track the serving beam, a beam recovery procedure is initialized. After successful completion of the beam recovery procedure, the UE retransmits the data stored in the UL HARQ buffer. The UE prevents the data from being flushed from the UL HARQ buffer when the failure to track the serving beam occurs, so that the data can be retransmitted.

  • METHOD AND APPARATUS FOR UE BEAMFORMING AND BEAM SWEEPING IN A WIRELESS COMMUNICATION SYSTEM
    Publication number: 20170373740
    Abstract: A method for a wireless communications system is disclosed. In one example, a user equipment (UE) device (e.g. a mobile phone) provides a UE beam sweeping number to a network node. Based on the UE beam sweeping number, the network node provides configuration information or allocates a resource to the UE device. The UE device can use the configuration information or the resource for measurement. The beam sweeping number refers to the number of time intervals that the UE device would need to generate multiple sets of UE beams, one set per time interval, that would cover all possible directions in which the UE device sends and/or receives transmissions, in a manner that resembles a sweeping of UE beams.

  • METHOD AND APPARATUS FOR PERFORMING UE BEAMFORMING IN A WIRELESS COMMUNICATION SYSTEM
    Publication number: 20170373731
    Abstract: A method for a wireless communications system is disclosed. In one example, a user equipment (UE) (e.g. a mobile phone), receives an indication from a network about one or more UE beams that the UE can use for transmission or reception. The UE uses the one or more UE beams for transmission or reception. If and when a certain condition is fulfilled, for example, there is a beam tracking failure, the UE transmits or receives a specific signal via a specific UE beam. The specific UE beam is different from the one or more UE beams that were indicated by the network, and is selected by the UE.
