ABSTRACT:
The present invention provides for spreading a first signal using a plurality of spreading codes, multiplexing the first spread signal by code division multiplexing, transmitting the first multiplexed signal via a plurality of neighboring frequency resources of an OFDM symbol of a first antenna set, spreading a second signal using a plurality of spreading codes, multiplexing the second spread signal by code division multiplexing, transmitting the second multiplexed signal via a plurality of neighboring frequency resources of the OFDM symbol of the first antenna set, transmitting the first multiplexed signal via a plurality of neighboring frequency resources of an OFDM symbol of a second antenna set, and transmitting the second multiplexed signal via a plurality of neighboring frequency resources of the OFDM symbol of the second antenna set, wherein the first multiplexed signal is transmitted on frequency resources that neighbor frequency resources that the second multiplexed signal is transmitted on.
