摘要： The present disclosure relates to a method and user equipment, UE, in a wireless communication network of performing power scaling on uplink transmission to a receiving radio access node, RAN. In particular, the disclosure relates to a method and user equipment for power scaling on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and an enhanced Dedicated Physical Data Channel, E-DPDCH are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining (S31) a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced (S32) to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. A DPDCH transmission status is determined (S33), whereupon a power scaling procedure is selected (S34) based on the determined DPDCH transmission status. The selected power scaling procedure is applied (S35) on the uplink transmission.

摘要： The present invention relates to a method, a communication system and a Node-B (NB) in a communication system for distribution of downlink E-DCH power usage in a communication system. The system comprises at least one Node-B (NB) for enabling wireless communication with at least one user terminal (UE). The communication is enabled via an enhanced dedicated transport channel (E-DCH) and one high speed downlink shared channel (HS-DSCH) for uplink (UL) and downlink (DL) data traffic between the user terminal (UE) and the Node-B (NB). The Node-B (NB) comprises a HSDPA scheduler (HS-S) for scheduling the data rate for the DL data traffic via the HS-DSCH. It further comprises an EUL scheduler (EUL-S) for scheduling the maximum data rate for the UL data traffic via the E-DCH. The method is particularly characterized in that the Node-B (NB) estimates 111 the power consumption and/or the corresponding transmission time for at least one forthcoming E-DCH DL transmission on at least one E-DCH physical channel. The Node-B (NB) sends 112 the estimated power consumption and/or the corresponding transmission time information to the HSDPA scheduler (HS-S) prior to the E-DCH DL transmission.

摘要： To combat base station power drift, the power transmission level of each base station in a diversity handover may be compared to a power reference established for all base stations in the diversity handover. The difference between the transmit power of each base station and the reference power threshold may then be used to correct the transmit power level of that base station. Because the power correction depends on the difference between the actual transmit power at the base station and the common power level reference, the various transmit powers of the different base stations in the diversity handover converge relatively quickly. Thus, even if the transmit power command from the mobile station is received in error in one or more of the base stations, the power correction based on the comparison to the common power reference compensates for such errors to reduce base station drift, obtain full diversity gain, and reduce unnecessary downlink interference. The reference power level(s) used in compensating for base station power drift is(are) advantageously determined using one or more parameters relevant to the current condition of the diversity handover communication. Rather than setting an arbitrary and static reference power level, the reference power level is set dynamically so that it is relevant to the current conditions of the diversity handover communication. Dynamic and adaptive reference power level setting results in more effective and more efficient downlink power control. Unnecessary power changes, both in frequency and in size, are avoided because the reference power level is more accurately determined for the current circumstances.
摘要翻译：为了抵抗基站功率漂移，可以将分集切换中的每个基站的功率传输级别与在分集切换中为所有基站建立的功率参考进行比较。然后可以使用每个基站的发射功率与参考功率阈值之间的差异来校正该基站的发射功率电平。由于功率校正取决于基站的实际发射功率与公共功率电平参考之间的差异，所以分集切换中的不同基站的各种发射功率相对较快地收敛。因此，即使在一个或多个基站中接收到来自移动台的发送功率指令有误，基于与公共功率基准的比较的功率校正来补偿这样的误差以减少基站漂移，获得全分集增益，减少不必要的下行链路干扰。使用与分集越区切换通信的当前条件相关的一个或多个参数有利地确定用于补偿基站功率漂移的参考功率电平。不是设置任意和静态参考功率电平，而是动态地设置参考功率电平，使其与分集越区切换通信的当前条件相关。动态和自适应参考功率电平设置导致更有效和更有效的下行链路功率控制。避免了在频率和尺寸上的不必要的功率变化，因为针对当前情况更准确地确定了参考功率电平。
