Indicating user equipment (UE) polorization tracking capacity

A method performed by an access node in a wireless communication network, the method comprising:

• configuring at least one downlink polarization of at least one downlink communication between a wireless terminal of the wireless communication network and the access node;
• selecting a reference polarization from the at least one downlink polarization;
• determining at least one uplink polarization of at least one uplink communication between the wireless terminal and the access node;
• and
• based on the at least one uplink polarization and the reference polarization, determining a polarization tracking ability of the wireless terminal.

A wireless terminal, comprising:

• an antenna array having antenna elements being associated with mutually orthogonal planes of polarization, and
• a processor being configured for
• using a polarization tracking capability of the wireless terminal, determining at least one downlink polarization of at least one downlink communication between the wireless terminal and an access node of the wireless communication network;
• selecting a reference polarization from the at least one downlink polarization determined using the polarization tracking capability;
• and
• based on the reference polarization and a polarization tracking ability of the wireless terminal, configuring at least one uplink polarization of at least one uplink communication between the wireless terminal and the access node.
