Abstract: A wireless communication device can expedite beam scans for beam management. The wireless communication device can perform a beam scan using a first beam reference signal of a synchronization signal block (SSB) and a second beam reference signal associated with a physical broadcast control channel (PBCH) of the SSB. For each synchronization signal block (SSB) index (e.g., transmit beam) monitored by the wireless communication device, the wireless communication device can obtain a respective beam quality metric on each of two or more respective receive beams using at least the first and second beam reference signals. Other aspects, features, and embodiments are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may perform beam measurements for one or more subsets of beams that are selected to provide enhanced beam switch determinations. The UE may identify one or more prioritized beams, and may measure the prioritized beams at a same periodicity as measurements of a serving beam. The UE may, additionally or alternatively, identify a set of all layer one beams (e.g., maximum-level beams or top level beams) for measurement according to a periodic interval, based on a measured mobility being less than a threshold value. The periodic interval may provide that each layer one beam may be measured at a cadence of one beam per measurement occasion, in order to provide measurement diversity.

Abstract: One embodiment of the invention describes a synchronization signal sending method applied to an unlicensed frequency band. To ensure transmission fairness, a network device performs listen before talk (LBT) before a start time for transmitting a synchronization signal, to determine whether a channel is busy or idle. When the channel is busy, the network device cannot transmit the synchronization signal at the expected start time for transmitting the synchronization signal. Therefore, the network device performs LBT again within a preset time length after the start time, and sends the synchronization signal when determining that the channel is idle by performing LBT again. When the channel is idle, the network device preempts a channel resource, and sends the synchronization signal the expected start time for transmitting the synchronization signal.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with one or more parameters to support blockage detection for beamformed communication. The UE may receive a set of reference signals via a receive beam of a beam pair. The UE may detect a condition associated with a measured signal quality of a reference signal of the set of reference signals relative to a filtered signal quality of the set of reference signals. The condition may, in some examples, correspond to a drop of the measured signal quality at least a threshold amount below the filtered signal quality for at least a threshold duration of time. The UE may delete one or more signal quality values from a measurement database of the UE based on detecting the condition. The one or more signal quality values may be associated with the beam pair.

In an aspect, during a first synchronization wakeup period while RF circuitry and the FW circuitry are set to an active state, one or more measurements of one or more SSBs of a first SSBS from a base station. The UE predicts, during the first synchronization wakeup period while the RF circuitry and the FW circuitry are in the active state, a second SSBS at which to wake up for a second synchronization wakeup period based on the one or more measurements. In response to completion of FW post-processing operations, the UE transitions the RF circuitry and the FW circuitry from the active state to a sleep state.

The circuit breaker further includes a locking member rotatably arranged inside the circuit breaker housing with an upper portion close to the limiting hole provided with a locking protrusion fitting. A lower portion of the circuit breaker housing is provided with a locking driving surface fitting with the opening and closing button.

The locking driving surface limits the opening and closing button, so that the opening and closing button cannot press to the destined position.
