1. A method, performed by a network node, for beam control signaling, wherein the network node is configured to communicate with a wireless device, the method comprising:
obtaining a first set of candidate beams, from the wireless device, for communication with the network node based on beam quality indicators, the first set of candidate beams based on a hardware capability of the wireless device;
determining a second set of candidate beams based on the first set and a number of beams to be used in the communication with the wireless device, wherein the second set of candidate beams is determined by reducing the first set of candidate beams such that the second set of candidate beams is a proper subset of the first set of candidate beams, the number of candidate beams of the second set is larger than the number of beams to be used for communication with the wireless device; and
transmitting, to the wireless device, control signaling indicative of the second set of candidate beams, wherein the wireless device is configured to select, among the second set of candidate beams, one or more beams for communication with the network node based on a hardware property of the wireless device, the hardware property is indicative of an association between a respective panel and a corresponding physical antenna panel or of power arrangement related to the physical antenna panels, each physical antenna panel comprises one or more panels.
