  • Publication number: 20210297175
    Abstract: Systems and methods of initial acquisition in a NR system are described. A UE receives time and frequency superposed SSBs from a gNB. If the PSS and SSS of each SSB is independent of a block index of the SSB, the UE receives an additional reference signal scrambled by a beam index of the SSB and uses the reference signal to discriminate between the SSBs. The reference signal is FDMed within a null-subcarrier region of the SSB or outside of the SSB. If the PSS and SSS of each SSB is scrambled using the block index, the UE separates the PBCH measurements, iteratively identifies a block index associated with a DMRS of the PBCH with the highest L1-RSRP level measurement, decodes and reconstructs the PBCH, and subtracts the reconstructed PBCH from the SSB before transmitting an indication of the PBCH with the highest L1-RSRP level measurement to the gNB.

  • Patent number: 11076424
    Abstract: Devices and methods of transmit opportunity (TXOP) with continued listen-before-talk (LBT) are generally described. A user equipment (UE) can be configured to perform a single LBT during an LBT scanning instance, to detect availability of an unlicensed wireless channel. Upon detecting availability of the channel, data is encoded for transmission during a TXOP with a TXOP duration. A pause in the transmission of the data is initiated upon expiration of a first time interval of the TXOP. A continuous LBT procedure is performed upon expiration of the pause, to determine a plurality of sensing metrics indicating occupancy of the unlicensed wireless channel. The transmission of the data is resumed during the TXOP for a second time interval, when at least one sensing metric of the plurality of sensing metrics is below a threshold.

The data preprocessing subsystem filters the input cloud computing log information for abnormal data and extracts the running time of each task. The task scheduling subsystem enqueues or dequeues tasks from the batch task and real-time task running queues of each node, and keeps the tasks currently running in the cluster consistent with the actual production environment, and updates the number of CPU cores and the used and available memory capacity of each node according to resource requirement of each task. The mixed scheduling simulation of batch tasks and online tasks can be realized, and the resource simulation of the heterogeneous CPU core number and memory capacity of the cluster nodes can be simulated.
