There is provided a method for scheduling user terminals for downlink transmission in a communication network, the method including determining a duration of a discontinuous reception cycle for a user terminal, wherein the beginning of the cycle triggers a first active period during which the user terminal is in an active mode; and determining an interval between periodic channel quality indicator reports for the user terminal. The method further includes aligning the discontinuous reception cycle with the interval between the periodic channel quality indicator reports such that the periodic channel quality indicator is transmitted within the first active period of the discontinuous reception cycle, receiving the periodic channel quality indicator during the first active period of each discontinuous reception cycle, thus obtaining an up-to-date channel quality indicator for the discontinuous reception cycle, and scheduling the user terminals for downlink transmission by taking the received periodic channel quality indicator into account.

Scheduling of user terminals in communication network

A scheduling processor allocates a time slot of a communication protocol to a user equipment for data transmission based on received control data of the same or another user equipment in a current time slot and received user data of the same or another user equipment in a preceding time slot, while ignoring user data of the same or any other user equipment received in the current time slot. The scheduling processor also allocates a frequency resource to the user equipment. A control channel managing processor allocates signaling resources on a control channel for the submission of control information to the user equipment, which informs of the time slot allocated by the time domain scheduling processor as well as of the frequency resource allocated by the frequency domain scheduling processor.
