Abstract
The present disclosure relates to a method 20 for broadcasting performed in a network node 11. The network node 11 is configured to broadcast information within a coverage area by using a directional beam. The method 20 comprises: determining 21 one or more directions for the directional beam based on a priori information about receiver 141 . . . , 14i . . . , 14N locations within the coverage area, and broadcasting 22 the information in the determined one or more directions.
Claims24
A method for broadcasting performed in a network node, the network node being configured to broadcast information within a coverage area by using a directional beam, the method comprising:
- determining one or more directions for the directional beam based on a priori information about receiver locations within the coverage area, wherein the a priori information about the receiver locations comprises directions in which receivers are presently located and/or directions in which the receivers have been previously located, wherein the determining the one or more directions comprises determining further directions corresponding, respectively, to directions in which the receivers are located with a non-increasing order of likelihood;
- and
- broadcasting the information in the determined one or more directions, wherein the broadcasting is performed first in a first direction and then in the determined further directions in the non-increasing order of likelihood.
A network node for broadcasting, the network node being configured to broadcast information within a coverage area by using a directional beam, the network node comprising:
- a processing circuit configured to determine one or more directions for the directional beam based on a priori information about receiver locations within the coverage area;
- and
- a transmitter configured to broadcast the information in the determined one or more directions,
- wherein the processing circuit is preconfigured with data on one or more directions that are excluded based on a placement of the network node.
A non-transitory computer-readable storage medium storing a computer program for a network node for broadcasting, the network node being configured to broadcast information within a coverage area by using a directional beam, the computer program comprising computer program code that, when executed on at least one processor of the network node, causes the network node to:
- determine one or more directions for the directional beam based on a priori information about receiver locations within the coverage area, wherein the a priori information about the receiver locations comprises directions in which receivers are presently located and/or directions in which the receivers have been previously located, wherein the determination of the one or more directions comprises a determination of further directions corresponding, respectively, to directions in which the receivers are located with a non-increasing order of likelihood;
- and
- broadcast the information in the determined one or more directions, wherein the broadcasting is performed first in a first direction and then in the determined further directions in the non-increasing order of likelihood.
