Abstract
A reference sequence may be transmitted in wireless communication, e.g. in order to perform channel estimation. The use of a reference sequence introduces overhead. In some embodiments, the subcarrier spacing (SCS) of the multi-carrier symbols (e.g. OFDM symbols) used to transmit one or more reference sequences is different from the SCS of the multi-carrier symbols used to transmit information (e.g. data). In some embodiments, an original reference sequence may be spread over multiple multi-carrier symbols, with each multi-carrier symbol carrying a respective reference sequence that is a portion of the original reference sequence. The technical benefit is possibly improved channel estimation because the original reference sequence is spread in time, but with the same overhead (in terms of total occupied time of reference symbols) as transmitting all of the original reference sequence at the same time.
