Abstract
Aspects of this disclosure relate receiving a reference symbol from at least one antenna. The reference symbol includes a portion of a first transmitted reference symbol and a portion of a second transmitted reference symbol. The first transmitted reference symbol includes a symbol and a cyclically shifted portion of the symbol having a cyclic shift length. The second transmitted reference symbol includes a cyclically shifted version of the first transmitted reference symbol that is cyclically shifted relative to the first transmitted reference symbol by the cyclic shift length. The reference symbol is processed. In certain embodiments, processing the reference symbol can account for (i) a frame offset between uplink symbols and downlink symbols and (ii) another timing offset between downlink transmission and uplink reception.
