Patent ID: 8345592

Claim:
A method for efficiently utilizing radio resources in a communication network comprising a communication network node transmitting information on control channels to one or more user equipments, comprising: defining a subset of Transmission Time Intervals in order to determine at which instances a control channel may address a user equipment in a power saving mode or non-power saving mode; defining a first, wideband mapping pattern for user equipments in a non-power saving mode; defining a second, narrowband mapping pattern for user equipments in a power saving mode; transmitting, during Transmission Time Intervals of a subset associated to a respective power mode, said information over the control channel by using the mapping pattern that is defined for the respective power mode of the user equipment; and wherein information is allowed to be transmitted over the control channel to user equipments in non-power saving modes by using the second mapping pattern if no information is to be transmitted to user equipments in a power saving mode.
