The wireless device comprises one or more antenna panels configured to communicate with a network node. The method comprises obtaining a capability of at least one of the antenna panels, wherein the capability comprises at least one of: a receive-only panel, ROP, capability, a transmit-only panel, TOP, capability, a receive-and-transmit panel, RTP, capability and a dynamic RTP capability. The method comprises transmitting, to the network node, control signalling indicative of the obtained capability of the at least one antenna panel. ## Claims ### Claim 1 A method, performed at a wireless device, for capability signalling, wherein the wireless device comprises one or more antenna panels configured to communicate with a network node, the method comprising: obtaining a capability of at least one of the antenna panels, wherein the capability comprises at least one of: a receive-only panel (ROP) capability, a transmit-only panel (TOP) capability, a receive-and-transmit panel (RTP) capability and a dynamic RTP capability; and transmitting, to the network node, control signalling indicative of the obtained capability of the at least one antenna panel. ### Claim 2 (depends on 1) The method according to claim 1, the method comprising: receiving, from the network node, control signalling indicative of one or more antenna panels to be activated; and activating the one or more panels indicated by the control signalling received. ### Claim 3 (depends on 1) The method according to claim 1, the method comprising: communicating, between the wireless device and the network node, control signalling indicative of switching of one of the antenna panels having a dynamic RTP capability from a first mode to a second mode, wherein the first mode comprises one of: a ROP mode, a TOP mode, a RTP mode and a deactivate mode, wherein the second mode comprises one of: a ROP mode, a TOP mode, a RTP mode and a deactivate mode; and switching the indicated antenna panel from the first mode to the second mode. ### Claim 4 (depends on 2) The method according to claim 2, the method comprising: establishing a beam pair for uplink and downlink in response to the switching and/or in response to the activating. ### Claim 5 (depends on 1) The method according to claim 1, wherein communicating, between the wireless device and the network node, control signalling indicative of switching of one of the antenna panels comprises receiving from the network node, control signalling instructing the wireless device to switch the one antenna panel from the first mode to the second mode. ### Claim 6 (depends on 1) The method according to claim 1, wherein communicating, between the wireless device and the network node, control signalling indicative of switching of one of the antenna panels comprises transmitting, to the network node, control signalling indicating to the network node that the wireless device intends to switch the one antenna panel from the first mode to the second mode. ### Claim 7 (depends on 3) The method according to claim 3, wherein the control signalling indicative of switching indicates a time period and wherein the method comprises performing an additional switching of the one antenna panel in response to expiry of the time period. ### Claim 8 A method, performed at a network node, wherein the network node is configured to communicate with a wireless device via one or more antenna panels of the wireless device, the method comprising: receiving, from the wireless device, control signalling indicative of a capability, the capability comprising at least one of: a receive-only panel capability, a transmit-only panel (TOP) capability, a receive-and-transmit panel (RTP) capability and a dynamic RTP capability; and scheduling transmission of the wireless device based on the capability indicated by the received control signalling. ### Claim 9 (depends on 8) The method according to claim 8, the method comprising: selecting, based on the capability indicated, one or more antenna panels to activate; and transmitting, to the wireless device, control signalling indicative of the selected one or more antenna panels. ### Claim 10 (depends on 8) The method according to claim 8, the method comprising: communicating, between the wireless device and the network node, control signalling indicative of switching of one of the antenna panels having a dynamic RTP capability from a first mode to a second mode, wherein the first mode comprises one of: a ROP mode, a TOP mode, a RTP mode and a deactivate mode, wherein the second mode comprises one of: a ROP mode, a TOP mode, a RTP mode and a deactivate mode. ### Claim 11 (depends on 10) The method according to claim 10, wherein communicating, between the wireless device and the network node, the control signalling indicative of switching of one of the antenna panels comprises transmitting to the wireless device, control signalling instructing the wireless device to switch the indicated antenna panel having a dynamic RTP capability from the first mode to the second mode. ### Claim 12 (depends on 10) The method according to claim 10, wherein communicating, between the wireless device and the network node, the control signalling indicative of switching of one of the antenna panels comprises receiving, from the wireless device, control signalling indicating to the network node that the wireless device intends to switch the one antenna panel from the first mode to the second mode. ### Claim 13 (depends on 8) The method according to claim 8, the method comprising: selecting, based on the capability indicated and received quality metrics per antenna panels, one or more antenna panels for communication. ### Claim 14 (depends on 8) The method according to claim 8, wherein scheduling transmission of the wireless device based on the capability indicated by the received control signalling comprises scheduling an uplink transmission for an antenna panel having at least one of: the TOP capability, the RTP capability and the dynamic RTP capability. ### Claim 15 (depends on 8) The method according to claim 8, wherein scheduling transmission of the wireless device based on the capability indicated by the received control signalling comprises scheduling a downlink transmission for an antenna panel having at least one of: the ROP capability, the RTP capability and the dynamic RTP capability. ### Claim 16 (depends on 1) A wireless device comprising a memory module, a processor module, and a wireless interface, wherein the wireless device is configured to perform the method of claim 1. ### Claim 17 (depends on 8) A network node comprising a memory module, a processor module, and a wireless interface, wherein the network node is configured to perform the method of claim 8. ### Claim 18 (depends on 1) The method of claim 1, wherein the control signalling is further indicative of a panel identifier. ### Claim 19 (depends on 8) The method of claim 8, wherein the control signalling is further indicative of a panel identifier.
