Method for scheduling of service data in downlink, a base station, a user terminal and a communication network therefor

A user terminal, comprising:

• a receiver configured to receive at least one control message from a base station, the at least one control message being for scheduling downlink service data to be sent from the base station to the user terminal over radio interfaces, wherein one or more of the at least one control message comprises at least one of an order when the user terminal shall perform reception of downlink data and an order when and under which circumstances the user terminal shall send HARQ feedback information in upcoming transmission time intervals;
• and
• at least one processor configured to evaluate the at least one control message;
• wherein the sending of the at least one control message is initiated by the base station after the base station detects a silence period in a persistently scheduled downlink between the base station and the user terminal through recognition of a reduction of a data rate of the service data sent to the user terminal.

A base station, comprising:

• at least one processor configured to generate at least one control message for scheduling downlink service data to be sent from the base station to a user terminal over radio interfaces, wherein the at least one control message comprises at least one of an order when the user terminal shall perform reception of downlink data and an order when and under which circumstances the user terminal shall send HARQ feedback information in upcoming transmission time intervals,
• wherein the at least one processor is also configured to detect a silence period in a persistently scheduled downlink between the base station and the user terminal through recognition of a reduction of a data rate of the service data sent to the user terminal;
• and
• a transmitter configured to transmit the at least one control message to the user terminal;
• wherein the at least one processor and transmitter are configured such that transmission of the at least one control message is initiated in conjunction with detection of the silence period.

A communication network for scheduling downlink service data, comprising:

• a user terminal;
• and
• a base station;
• the user terminal comprising
• a receiver configured to receive at least one control message from the base station, the at least one control message being for scheduling downlink service data to be sent from the base station to the user terminal over radio interfaces, wherein one or more of the at least one control message comprises at least one of an order when the user terminal shall perform reception of downlink data and an order when and under which circumstances the user terminal shall send HARQ feedback information in upcoming transmission time intervals;
• and
• at least one terminal processor configured to evaluate the at least one control message;
• the base station comprising
• at least one station processor configured to generate said at least one control message,
• wherein the at least one station processor is also configured to detect a silence period in a persistently scheduled downlink between the base station and the user terminal through recognition of a reduction of a data rate of the service data sent to the user terminal;
• and
• a transmitter configured to transmit the at least one control message to the user terminal;
• wherein the at least one station processor and transmitter are configured such that transmission of the at least one control message is initiated in conjunction with detection of the silence period.
