Method for transmitting data between a user equipment and a base station in a wireless radio network

A base station for a wireless radio network, comprising:

• a plurality of antennas for transmitting radio frequency signals between the base station and a user equipment, wherein the user equipment comprises at least a first antenna and a second antenna for transmitting radio frequency signals between the user equipment and the base station, and
• a processing device configured to
• receive a first training signal sent from the user equipment to the base station via the first antenna at a first time period,
• determine for each antenna of a subset of the plurality of the antennas of the base station a corresponding first configuration parameter based on the first training signal received at the corresponding antenna,
• receive a second training signal sent from the user equipment to the base station via the second antenna at a second time period different to the first time period,
• determine for each antenna of the subset of the plurality of the antennas of the base station a corresponding second configuration parameter based on the second training signal received at the corresponding antenna,
• transmit first downlink data from the base station to the user equipment using the determined first configuration parameters for the antennas of the base station, and simultaneously transmit second downlink data from the base station to the user equipment using the determined second configuration parameters for the antennas of the base station, and
• either receive uplink data sent from the user equipment via the first antenna using the first configuration parameter or receive uplink data sent from the user equipment via the second antenna using the second configuration parameter.
