  • METHOD AND APPARATUS FOR TRANSMISSIONS VIA MULTIPLE BEAMS IN A WIRELESS COMMUNICATION SYSTEM
    Publication number: 20180013481
    Abstract: A method for a wireless communications system is disclosed. In one example, user equipment (UE) (e.g. a mobile phone) receives an indication from a network (for example, by way of a transmission and reception point (TRP)) indicating whether a first transmission and a second transmission to the UE can be combined for decoding. The UE also receives the first transmission via a first UE beam and the second transmission via a second UE beam. The first transmission and the second transmission are received concurrently. The first and second transmissions can arrive via different serving beams and/or different TRPs of the same cell. Based on the indication, the UE combines the first and second transmissions for decoding purposes.

  • 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.
