1. A device attachable to a wireless network via a radio interface, comprising:
- an antenna array configured to execute transmission on a plurality of beamformed directions, andat least one processor configured to determine, based on at least one spatial information of the device, antenna weights of the plurality of beamformed directions,wherein the at least one processor is configured to control the antenna array, based on the antenna weights, to sequentially execute transmission on the plurality of beamformed directions and to prioritize transmission on a first beamformed direction of the plurality of beamformed directions over transmission on a second beamformed direction of the plurality of beamformed directions,wherein the at least one processor is configured to control the antenna array to prioritize transmission on the first beamformed direction over transmission on the second beamformed direction by at least one of setting a temporal sequence of transmission on the plurality of beamformed directions and setting a frequency of occurrence of transmission on each one of the plurality of beamformed directions.

Abstract
Antenna weights of a plurality of beamformed directions are determined. Transmission on the first beamformed direction is prioritized over transmission on the second beamformed direction, e.g., during beam sweeping. Such techniques may find application in discovery of an access node by a device attached to a wireless network.
