Method and communication apparatus for transmitting and receiving channel state information for a radio channel between a telematics communication unit and a base station

A server for controlling a Telematics Communication Unit (TCU) mounted on a vehicle in a next-generation mobile communication system, comprising:

• a transceiver;
• and
• a processor for controlling the transceiver,
• wherein the processor is configured to perform:
• controlling the transceiver to receive channel state information for a radio channel between the TCU and a base station from a mobile communication network including the base station;
• determining a data rate available for a combination of a plurality of transmit beams of the base station and a plurality of receive beams of the TCU based on the channel state information;
• controlling the transceiver to receive a data request message of the TCU from the mobile communication network,
• wherein the data request message includes information related to first data requested by the TCU;
• determining a first transmission beam to be used for transmission of the first data based on the data request message of the TCU and the determined available data rate;
• and
• controlling the transceiver to transmit the first data and information on the first transmission beam to the mobile communication network,
• wherein the data request message further includes information related to Ethernet communication speed of the TCU.
