Patent ID: 8737530

Claim:
A base station for communicating with a mobile terminal, the base station comprising: a first antenna that transmits a first signal; a second antenna that transmits a second signal, the first antenna and the second antenna provide a Multiple Input Multiple Output, MIMO, communications to the mobile terminal; and a transmitter configured to determine a first training sequence for the first antenna, the first training sequence being for use by the mobile terminal to estimate a channel via which the first signal is received, prepare a first data payload, generate the first signal including the prepared first data payload and the first training sequence, transmit the first signal from the first antenna for reception by the mobile terminal, determine a second training sequence for the second antenna, the second training sequence being for use by the mobile terminal to estimate a channel via which a second signal is received, wherein the second training sequence is different from the first training sequence, prepare a second data payload, generate the second signal including the prepared second data payload and the second training sequence, and transmit the second signal, at a same time as the first signal, from the second antenna.
