1. A method, performed in a wireless device, for polarization reporting, wherein the wireless device is configured to communicate with an associated network node using a plurality of antenna panels of the wireless device, including a first antenna panel and a second antenna panel arranged spaced apart in the wireless device such that the first antenna panel is configured to receive and/or transmit radio signals in a first direction via a first beam, whereas the second antenna panel is configured to receive and/or transmit radio signals in a second direction via a second beam, wherein the first and second beams have different spatial directions, the method comprising:
generating, based on one or more polarization properties of the first antenna panel, a first polarization indicator associated with a first identifier, wherein the first identifier comprises:
a first antenna panel identifier that establishes an identity of the first antenna panel amongst the plurality of antenna panels of the wireless device that is to be used for transmitting a capability report; and
a first beam identifier that indicates the first beam of the first antenna panel of the wireless device that is to be used for transmitting the capability report; and
transmitting the capability report to the associated network node using the first beam of the first antenna panel, the capability report comprising the first polarization indicator associated with the first identifier.
