Abstract
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.

A method of enabling 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 method comprising:
- providing said communication network node with information about a power shortage problem in a user equipment by using a pre-determined field of said uplink channel during a retransmission;
- predicting a targeted number of transmission attempts;
- changing said pre-determined field signalling a power shortage problem when the target number of transmissions has been transmitted;
- and
- retransmitting said data whereby said retransmission comprises said changed pre-determined field;
- and
- the communication network node using the information to take a pre-determined action regarding available radio resources.
An arrangement for enabling an efficient radio resources utilization in a communication network comprising a communication network node communicating with one or more user equipments over a radio interface on uplink and downlink channels, the arrangement comprising:
- means for providing said communication network node with information about a power shortage problem in a user equipment by using a pre-determined field of said uplink channel during a retransmission;
- means for predicting a target number of transmission attempts;
- means for changing said pre-determined field signalling a power shortage problem when the predicted target number of transmissions has been transmitted;
- means for retransmitting said data whereby said retransmission comprises said changed pre-determined field;
- and
- wherein the communication network node being arranged to use the information about the power shortage problem to take a pre-determined action regarding available radio resources.
