Abstract
Techniques for transmitting and receiving a reference signal in a wireless network are described. In one design, a UE may generate multiple transmissions of a reference signal at multiple frequency locations. The UE may send the transmissions of the reference signal in multiple symbol periods of at least one subframe. The UE may send at least two transmissions of the reference signal in each subframe, e.g., one transmission of the reference signal in each symbol period of a subframe. Each transmission of the reference signal may cover a portion of the bandwidth of the reference signal and may be sent on a set of contiguous subcarriers at a particular frequency location. The multiple transmissions of the reference signal may cover the entire bandwidth of the reference signal. A location estimate for the UE may be determined based on time of arrivals (TOAs) of the reference signal measured by multiple receiver stations.
