Methods, devices, and computer program for uplink communication

A method for uplink communication with a network node, wherein the method is performed by a first transceiver device, the method comprising:

• exchanging signaling with the network node to form a reconfigurable virtual user equipment (RVUE) comprising a group of transceiver devices, the group of transceiver devices comprising the first transceiver device and a second transceiver device, and wherein the signaling at least indicates available number of antenna ports of the RVUE for communication with the network node, and maximally support transmission rank for the RVUE;
• receiving configuration from the network node for uplink transmission from the R VUE to the network node, wherein the configuration at least indicates which transmission rank for the RVUE to use, and a mapping of transmission layers to the antenna ports in the RVUE;
• and
• performing uplink transmission towards the network node in accordance with the received configuration.
