POWER CONTROL DURING COMPRESSED MODE

摘要

A method and apparatus are provided for implementing a compressed mode of operation in a mobile communication network in which data transmission and reception is ceased so a required measurement can be made (42), wherein the power level of data transmission is adjusted to a correct power level before a subsequent data transmission is sent (44). The compressed mode may be implemented using a single frame method, in which control channels and power control commands are sent in the last slots of a single frame. The compressed mode may also be implemented using a double frame method, in which control channels and power control commands are sent in the beginning slots of a second frame. The method is implemented during a hard handover procedure, such as an intersystem handover. The measurement includes an inter-frequency measurement.
