ol command in the uplink direction there is an SIR target set for each cell in the active set. The UE lowers its transmission power when all the SHO connections fail to reach the SIR target. This means that transmission power is increased only if all connections are below the set SIR target. Outer Loop Power Control The outer loop power control algorithm adjusts the signal-to-interference ratio (SIR) target. The SIR target is used by the closed loop power control as a reference value for transmission power adjustments. The outer loop power control measures the block error rate (BLER), indicating the transport channel quality. There are individual BLER targets set for each transport channel; if the BLER target is not reached, at least for one of the transport channels, the outer loop power control increases the SIR target for the dedicated physical channels. Adjustment of the SIR target would make the closed loop power control algorithm adjust the transmission power of the dedicated physical channels. There are independent outer loop power control entities in both the uplink and downlink directions. The outer loop power control entity in the UE receives the BLER target, the initial SIR target and the minimum and maximum values for the SIR target in the radio bearer configuration message. Packet Data Connection Packet data is one example of non-real-time service. As currently the applications using packet data vary from email client, Internet surfing to music download the services use the packet data connection. Depending on the service requirements (QoS), the corresponding physical resources are allocated. In contrast to the real time services, the packet data as non-real-time services can momentarily lower their bit rate. Also in a case of inactivity the service can use common channels (Cell_FACH) to transmit small amounts of data or can, in the case of inactivity, use the idle mode, as in packet transfer states (Cell_PCH or URA_PCH) where no data are transferred.
