摘要： A method and arrangement is provided for adjusting the transmission power of radio signals sent over a radio link from a second node to be received by a first node reducing the transmission power consumption and/or optimizing the radio system capacity. The first node maintains a quality target of the link by generating a SIR target value by means of running an outer loop power control, which SIR target value is used for generating a power adjustment command to be sent to the second node for adjusting the transmission power such that a power level adequate for providing the quality target of the link is achieved. The method comprises the step of detecting an abrupt change in the conditions of the radio signals received from the second node, generating a temporary SIR target value, and replacing the SIR target value generated by the outer loop power control with the temporary SIR target value when generating the power adjustment command to be sent to the second node for adjusting the transmission power.

摘要： In a cellular radio system Transmission Power Control (TPC) power offset is set sothat it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC "up" and the number of TPC "down" sent bya radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.
摘要翻译：在蜂窝无线电系统中，传输功率控制（TPC）功率偏移被设置为基于可反映进行上行链路TPC命令的下行链路信道的质量的可用的相关测量来调整每个发射无线电基站，由此获得改进的性能。 TPC功率偏移可以例如基于由无线电基站发送的估计的上行链路专用物理控制信道（DPCCH）SINR，TPC“up”的数量和“下”的数量，以及聚合的UE接收机功率或UE传输上电N个插槽。此外，支持软切换的蜂窝无线电系统中使用的移动站也可以适用于基于同时接收的TPC命令的数量和质量来应用TPC丢弃阈值。也可以选择性地执行移动台中的丢弃过程，使得被确定为不可靠的TPC命令不被丢弃，而是基于它们被确定的可靠性而被选择性地丢弃。

摘要： Scheduling of high bit rate users causes rapid and large changes in the interference situation due to the bursty nature of traffic. Fast power control is not able to adapt to these fast changes in the interference situation. It is the basic idea of the present invention to remove the existing dedicated physical control channels both in the uplink (UL) and downlink (DL), i.e. the UL DPCCH and F-DPCH as defined in release 6 of the 3GPP-specif ications, for scenarios where all data and higher layer signaling is sent on EUL and HSDPA. Instead, the network signals to the UE a value of the total expected received interference (lexpected) at the radio base station based on which the UE can estimate the necessary uplink power.
摘要翻译：由于业务的突发性，高比特率用户的调度导致干扰情况的快速和大的变化。快速的功率控制不能适应干扰情况下的这些快速变化。本发明的基本思想是去除上行链路（UL）和下行链路（DL）中现有的专用物理控制信道，即在3GPP规范的版本6中定义的UL DPCCH和F-DPCH，对于在EUL和HSDPA上发送所有数据和更高层信令的场景。相反，网络向UE指示在无线电基站处的总预期接收干扰（预期）的值，基于该值，UE可以估计必要的上行链路功率。

摘要： In a radio access network (10) comprising a radio network controller node (26) and a base station node (28). a code tree has spreading codes which are allocatable between high speed downlink shared (HS-DSCH) channels and dedicated (DCH) channels. According to one aspect of the technology, use of the spreading codes of the code tree is monitored and an HS-DSCH channel is allocated a free spreading code which is non-adjacent to a spreading code already allocated to the HS-DSCH channels. In some example implementations, the free, non-adjacent spreading code is allocated so that more than one high speed channel user can use the spreading codes. In other example implementations, the free, non-adjacent spreading code is allocated so that one user uses the spreading codes by using more than one HS-SCCH channel. Preferably the non-adjacent spreading code is released from the HS-DSCH channel when the non- adjacent spreading code is needed for use by a DCH channel.
