  • System information updates in band width part (BWP) switch operation
    Patent number: 10743238
    Abstract: A user equipment (UE) for wireless communication is configured to perform bandwidth part (BWP) switching operation in response to receiving a system information change indication. The UE receives the system information change indication via a currently active BWP in a BCCH modification period. The system information change indication notifies the UE that contents of system information have been changed. The UE switches from the currently active BWP to an initial active BWP to receive the changed contents of system information which are required for the UE. The UE receives the changed contents of system information via the initial active BWP in a next BCCH modification period that immediately follows the BCCH modification period. The UE updates the system information according to the changed contents.

  • Interaction mechanism between radio link monitoring/radio link failure (RLM/RLF) and beam failure recovery procedure
    Patent number: 10728778
    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.

  • BEAM FAILURE DETECTION AND RECOVERY
    Publication number: 20200236570
    Abstract: A user equipment (UE) is configured with at least one bandwidth part (BWP) specific configuration information. The UE receives a configuration information specific to the bandwidth part (BWP). The configuration information configures an initial value of a beam failure detection (BFD) timer and a beam failure indication (BFI) count threshold. The UE starts or re-starts the BFD timer from the initial value when receiving a beam failure indication (BFI) from a lower sublayer, and counts a number of the received BFIs using a BFI counter. The UE resets the BFI counter to zero when receiving a reconfiguration information. The reconfiguration information, that is specific to the BWP, re-configures at least one of the initial value of the BFD timer and the BFI count threshold.
