The third reason for TDD is easier power control. In the TDD mode both the uplink and downlink transmissions use the same frequency; thus, the fast fading characteristics are similar in both directions. The TDD transmitter can predict the fast fading conditions of the assigned frequency channel based on received signals. This means that closed-loop power control is no longer needed, but only open loop will be sufficient. However, openloop control is based on signal levels, and if the interference level must be known, then this must be reported using signaling.

As in GSM, all HOs are managed by the network. For this purpose the network measures the uplink connection(s) and receives measurement results from downlink connection(s) made by the UE. The cells to be measured are divided into three sets: active, monitored, and detected. Each set has its own requirements on how to perform measurements in the cells. The active set contains all those base stations involved in an SHO with a UE. When the signal strength of a base station transmission exceeds the addition threshold in the UE, this base station is added to the active set and the UE enters into an SHO state if it is not already there.

6 MHz. The narrowest bandwidth (30 kHz) is the same as in IS-136, but it uses a different modulation. The 200-kHz carrier uses the same parameters as GSM EDGE and Introduction to 3G Mobile Communications 12 OVERVIEW provides data rates up to 384 Kbps. This carrier is designed to be used for outdoor or vehicular traffic. 6-MHz carrier is for indoor usage only, and can provide data rates up to 2 Mbps. UWC-136 supporters included North American IS-136 operators. This system is called IMT-SC in IMT-2000 jargon.
