  • Publication number: 20190141552
    Abstract: A user equipment for a wireless communication is configured to interact the radio link monitoring and beam failure recovery for resolving radio link failure quickly. When the out-of-synchronization (OOS) condition is detected in PHY sublayer, a timer may start to wait to receive a beam recovery success indication. Once the beam recovery success indication is received in RRC sublayer, the RRC sublayer may determine to consecutively receive a number of in-synchronization (IS) indications. If the number of the consecutively received IS indication is larger than or equal to a threshold number by comparing, the radio link is identified as being recovered.

  • Publication number: 20190110300
    Abstract: A method for a UE includes determining whether a contention-free random access resource associated with a first Synchronization Signal Block (SSB) is received, when received, determining whether a first Synchronization Signal-Reference Signal Received Power (SS-RSRP) of the first SSB is greater than a first threshold, when the first SS-RSRP of the first SSB is greater than the first threshold, selecting, by the processing circuitry, a beam associated with the contention-free random access resource associated with the first SSB for transmitting a random access preamble. If the first SS-RSRP of the first SSB is not greater than the first threshold, the method includes selecting a beam associated with a contention-based random access resource associated with a second SSB for transmitting the random access preamble, where a second SS-RSRP of the second SSB is greater than the first threshold.

  • Patent number: 5458448
    Abstract: An expansion bolt includes an elongated bolt body having a threaded section formed on one end and an expanded shoulder portion formed on an opposite end. An expansion cylinder slidably fits over the bolt body has a flat end supported by the shoulder and slits formed on the opposite end. An expanding ring has an inclined outer surface with the small end insertable into the slitted end of the expansion cylinder is slidably fit over the bolt body to have the small end thereof facing the slitted end of the expansion cylinder. A collar nut retains the expansion cylinder and the expanding ring on the bolt body with a support cylinder disposed between the collar nut and the expanding ring so that when the nut is tightened, the support cylinder forces the expanding ring toward the expansion cylinder to have the small end of the expanding ring wedge into and thus flaringly expand the slitted end of the expansion cylinder. The flaring tips of the slitted end are forced to be in tight contact engagement with a hole.
