USER TERMINAL POWER SHORTAGE INDICATION

摘要

A method and an arrangement enables an efficient radio resources utilization in a communication network system comprising a communication network node communicating with one or more user equipments over a radio interface on uplink and downlink channels. The user equipment provides the communication network node with information about a power shortage problem in the user equipment by using a pre-determined field, such as the E-TFCI field, of the uplink channel, whereby the communication network node is allowed to take a pre-determined action regarding available radio resources.
