Abstract
For controlling radio transmission in a cellular network, a network node detects data traffic between the cellular network and a user equipment. The detected data traffic is based on a transport protocol which involves transmission of an acknowledgement to acknowledge successful reception of data by the user equipment. The network node estimates a time at which sending of an future acknowledgement by the user equipment is expected. On the basis of the estimated time, the network node allocates UL radio resources to the user equipment. By sending an uplink grant, the network node may indicate the allocated uplink radio resources to the user equipment.
Claims21
A method of controlling radio transmission in a cellular network, the method comprising:
- detecting by a network node (100) detecting data traffic between the cellular network and a user equipment, the data traffic being based on a transport protocol which involves transmission of an acknowledgement to acknowledge successful reception of data by the user equipment;
- estimating by the network node a time at which sending of an future acknowledgement by the user equipment is expected;
- and
- on the basis of the estimated time, allocating by the network node uplink radio resources to the user equipment;
- and
- indicating by the network node the allocated uplink radio resources to the user equipment.
A network node for a cellular network, the network node comprising:
- an interface for transmission of data packets with respect to a user equipment;
- and
- at least one processor,
- wherein the at least one processor is configured to:
- detect data traffic between the cellular network and the user equipment, the data traffic being based on a transport protocol which involves transmission of an acknowledgement through the interface to acknowledge successful reception of data by the user equipment;
- estimate a time at which sending of an future acknowledgement by the user equipment is expected;
- and
- on the basis of the estimated time, allocate uplink radio resources to the user equipment;
- and
- indicate the allocated uplink radio resources to the user equipment through the interface.
