    Abstract: Techniques for multiplexing pilots in a wireless transmission are described. In one aspect, a transmitter station generates multiple pilot sequences for multiple transmit antennas, with each pilot sequence comprising pilot symbols sent in the time domain on a different set of subcarriers. The transmitter station further generates multiple pilot transmissions for the transmit antennas based on the pilot sequences. In another aspect, a transmitter station generates multiple pilot sequences for multiple transmit antennas based on frequency-domain code division multiplexing (FD-CDM) of a Chu sequence defined by a transmitter-specific value. The transmitter station further generates multiple pilot transmissions for the transmit antennas based on the pilot sequences. In yet another aspect, a transmitter station generates multiple pilot transmissions for multiple transmit antennas based on a first multiplexing scheme and generates multiple data transmissions based on a second multiplexing scheme that is different from the first multiplexing scheme.

    Abstract translation: 描述用于在无线传输中复用导频的技术。 在一个方面,发射机站为多个发射天线生成多个导频序列,每个导频序列包括在不同子载波集上的时域中发送的导频符号。 发射台还根据导频序列进一步为发射天线产生多个导频传输。 在另一方面,发射机站基于由发射机特定值定义的楚序列的频域码分复用(FD-CDM),为多个发射天线生成多个导频序列。 发射台还根据导频序列进一步为发射天线产生多个导频传输。 在另一方面,发射机站基于第一复用方案为多个发射天线生成多个导频传输,并且基于与第一复用方案不同的第二复用方案来生成多个数据传输。
