    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for beam recovery and radio link failure (RLF) in communications systems using beamforming and operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes communicating using beamforming with a base station (BS) via a transmit beam and a receive beam of an active beam pair and obtaining an indication of one or more alternative beams for the UE to use to send a beam recovery message to the BS in the event the transmit beam and the receive beam of the active beam pair become misaligned.

    Abstract: Certain aspects of the present disclosure provide techniques for using beam sets for mobility management. A BS serving the UE may transmit, to the UE, information regarding one or more beam sets, wherein each of the beam sets comprise one or more reference beams used to transmit a reference signal. The BS may transmit, to the UE, one or more mobility parameters, wherein the mobility parameters are associated with the reference beams and one or more mobility event triggers. The BS may receive, from the UE, an indication of a detected mobility event, the mobility event is detected based, at least in part, on the mobility parameters. The BS may take one or more actions based, at least in part, on the indication. A UE may perform corresponding steps as described herein.

    Abstract: A method of initiating handover preparation of a subset of a plurality of cells in a wireless communication network for a mobile device includes determining a first set of candidate cells of the plurality of cells in the wireless communication network. In one aspect, the method includes obtaining one or more of backhaul performance data, historical mobility data, or historical handover data and adding at least one candidate cell of the first set of candidate cells to the subset of cells based on the one or more data. The method then includes generating and sending a handover request message from the serving cell to each of the cells included in the subset of cells to initiate handover preparation of the mobile device from the serving cell.

    Abstract: Networks that support 5G communication may support different numerologies across and even within a symbol, slot, or subframe. Sequences, such as reference signals or data scrambled with a scrambling code, may be transmitted on resources with such mixed numerologies. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment. The UE may be configured to receive an indication of assigned resources for communicating with a base station. The UE may also be configured to determine a numerology associated with the assigned resources, and to determine one or more indices based on the numerology. The UE may also generate a sequence based on the one or more indices and communicate with the base station based on the sequence.
