Abstract: 回線設計補助装置は、伝搬損失算出式と、複数の手法の空中線結合損失式と、状況特定パラメータとを用いて、伝搬損失Ｌの推定値を算出する。回線設計補助装置は、送信側アンテナと受信側アンテナの間の電波の送受信に基づいて記録された伝搬損失の実測値と、伝搬損失Ｌの推定値との関係に基づいて、その伝搬損失Ｌの推定値が伝搬損失の実測値に近づく、伝搬損失算出式の特定と、その伝搬損失算出式に用いられる大気構造パラメータＭの特定とを用いて行う。回線設計補助装置は、複数の異なる送信側アンテナの設置位置と受信側アンテナの設置位置の組み合わせ毎に、学習部が特定した伝搬損失算出式と大気構造パラメータとを記録する。

Abstract: A method is disclosed for a sensing coordination device associated with one or more wireless sensing devices comprising a first wireless sensing device. The method comprises determining a threshold value for the first wireless sensing device, wherein the threshold value is for comparison with a difference between channel estimates of wireless sensing measurements of the first wireless sensing device, and causing application of the threshold value in control of operation of the first wireless sensing device for performing wireless sensing measurements. A method for the first wireless sensing device is also disclosed. The method comprises acquiring the threshold value, and operating the first wireless sensing device based on the threshold value, wherein operating the first wireless sensing device based on the threshold value may comprise refraining from transmitting a report of the wireless sensing measurements when the difference between channel estimates of the wireless sensing measurements is less than the threshold value. Corresponding apparatuses, devices and computer program product are also disclosed.

Abstract: 一种馈电网络、基站天线及基站设备，馈电网络包括馈电检测单元和位于同一馈电链路的第一馈电点和第二馈电点，馈电检测单元在馈电链路处于预设工作状态时根据第一馈电点处的第一电信号和第二馈电点处的第二电信号确定出馈电链路的驻波比，若馈电链路的驻波比与预设工作状态所对应的驻波比不匹配，则确定馈电链路连接异常。通过在馈电网络中设置馈电检测单元，不仅能在出厂基站天线之前提前校准基站天线内部的线缆连接，还能在连线外部设备后进一步检出基站天线外部的线缆连接问题，以便于投放或安装线缆连接无误的基站设备，降低基站设备返厂维修及用户重新部署基站天线的概率。

Abstract: 本申请实施例提供一种控制信道资源的确定方法、设备及存储介质，用于提高PDCCH的接收性能，降低SIB1的传输延迟。该方法包括：UE接收多个SSB，其中多个SSB中的每个SSB包含CORESET信息和SSB索引信息，针对每一个SSB，UE根据SSB包含的CORESET信息和SSB索引信息确定SSB对应的CORESET信息。UE确定的包含不同索引信息的多个SSB对应的CORESET信息不完全相同，UE根据多个SSB对应的CORESET信息检测PDCCH。由于不同索引的SSB对应CORESET信息不完全相同，UE可以在同一时间单元的不完全相同的CORESET上接收不同索引SSB对应的PDCCH，提高了PDCCH的接收性能，降低了UE接收SIB1的延迟，使系统设计更加灵活。

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a guard period associated with switching from a first communication mode to a second communication mode. The UE may be operating in a half-duplex frequency division duplexing mode of operation. The guard period may be determined based at least in part on at least one of: a number of phased locked loops to be used for the first communication mode and the second communication mode, and a particular subcarrier spacing associated with the UE. The UE may switch from the first communication mode to the second communication mode based at least in part on the guard period. Numerous other aspects are provided.

Abstract: A method of efficient wideband operation for intra-band non-contiguous spectrum using extending bandwidth part (BWP) configuration is proposed. The BWP definition is extended to cluster BWPs to aggregate distributed spectrum blocks within a frequency range (e.g., 200MHz) by single carrier operation and facilitate UE to filter out the transmission of unknown RAT between any two of the distributed spectrum blocks. In addition, the cluster BWP configuration enables dynamic aggregation of the number and location of the distributed spectrum blocks based on LBT results in unlicensed spectrum. Specifically, the BWP definition is extended to a group of one or multiple radio resource clusters, each of which contains a set of contiguous PRBs in frequency domain within the associated carrier.
