Claim 5:
6. An antenna device adapted for use in an antenna arrangement of a distributed massive Multiple Input Multiple Output (MIMO) system, wherein the distributed massive MIMO system comprises a central unit and wherein the antenna arrangement comprises a chain of antenna devices, including the antenna device, the antenna device comprising:
an antenna element and processing circuitry configured for performing per-antenna-element processing with respect to the corresponding antenna element;
wherein the processing circuitry in each antenna device is configured to:
locally perform a channel estimate based on a pilot signal received at the antenna device from a wireless communication terminal;
receive a data signal from a previous antenna device in the chain of antenna devices; and
process the data signal by using the channel estimate to form a transmission signal.
