Method and network node for broadcasting

A network node for broadcasting, the network node being configured to broadcast signals to communication devices located within a coverage area of the network node, the network node comprising a processor and memory, the memory containing instructions executable by the processor, whereby the network node is operative to:

• establish location information for a subset of the communication devices, the subset comprising communication devices targeted by the broadcast signal;
• establish at least one antenna pattern based on the determined location information for the subset of communication devices;
• broadcast according to the established at least one antenna pattern;
• update, by repeating the establishing of information and the establishing of at least one antenna pattern, the at least one antenna pattern based on updated location information for the subset of communication devices and/or based on communication devices being included in or excluded from the subset comprising communication devices;
• broadcast according to the updated at least one antenna pattern;
• and
• determine, for an antenna pattern comprising at least two beams, a transmission power level to be used for each of the at least two beams based on quality of service of the subset of communication devices in the direction of the respective beam and/or based on distance between the network node and the subset of communication devices.

A non-transitory computer readable storage medium comprising a computer program for a network node for broadcasting, the network node being configured to broadcast signals to communication devices located within a coverage area of the network node, the computer program comprising computer program code, which, when executed in the network node causes the network node to:

• establish location information for a subset of the communication devices, the subset comprising communication devices targeted by the broadcast signal;
• establish at least one antenna pattern based on the determined location information for the subset of communication devices;
• broadcast according to the established at least one antenna pattern;
• update, by repeating the establishing of information and the establishing of at least one antenna pattern, the at least one antenna pattern based on updated location information for the subset of communication devices and/or based on communication devices being included in or excluded from the subset comprising communication devices;
• broadcast according to the updated at least one antenna pattern;
• and
• determining, for an antenna pattern comprising at least two beams, a transmission power level to be used for each of the at least two beams based on quality of service of the subset of communication devices in the direction of the respective beam and/or based on distance between the network node and the subset of communication devices.
