阅读说明：本技术 随机接入规程期间的上行链路发射功率控制 (Uplink transmit power control during random access procedure ) 是由 M·N·*** S·萨布拉马尼安 B·萨迪格 N·阿贝迪尼 于 2018-06-22 设计创作，主要内容包括：在调整上行链路发射功率时,可使用发射波束成形增益和接收波束成形增益。例如,用户装备(UE)可在具有与针对上行链路发射波束的波束成形增益不同的波束成形增益的接收波束上接收来自基站的下行链路通信。该UE可基于这些波束成形增益的差异来调整(例如,用于传送随机接入信道(RACH)的)上行链路发射功率。例如,在确定用于RACH传输的经调整上行链路发射功率时,除最大允许发射功率、目标前置码收到功率和估计路径损耗外,还可使用表示这些波束成形增益的差异的参数。该调整可导致更高或更低的发射功率,这取决于接收波束成形增益和发射波束成形增益的差异。(In adjusting the uplink transmit power, transmit beamforming gain and receive beamforming gain may be used. For example, a User Equipment (UE) may receive downlink communications from a base station on a receive beam having a beamforming gain different from a beamforming gain for an uplink transmit beam. The UE may adjust uplink transmit power (e.g., for transmitting a Random Access Channel (RACH)) based on the differences in the beamforming gains. For example, in determining the adjusted uplink transmit power for RACH transmission, parameters representing differences in these beamforming gains may be used in addition to the maximum allowed transmit power, the target preamble received power, and the estimated path loss. This adjustment may result in higher or lower transmit power depending on the difference in receive and transmit beamforming gains.)
