| titleOfInvention | Staggered pilot transmission method and apparatus for channel estimation and time tracking |
| abstract | In order to allow the receiving entity to obtain a longer channel estimate while limiting the overhead, the transmitting entity transmits the pilot on different subband groups in different time intervals. N subbands in the system are arranged into M non-overlapping groups. Each group includes subbands uniformly distributed across the N subbands. The transmitting entity transmits the pilot on a different subband group at each time interval and selects all M subband groups in the M time intervals based on the pilot staggering pattern. The receiving entity (1) obtains an initial impulse response estimate with P channel taps based on the pilot received over one subband group, and (2) two with different lengths used for data detection and time tracking. Obtain longer impulse response estimates. Each longer impulse response estimate may be obtained by filtering the initial impulse response estimates for a sufficient number of subband groups using a time-domain filter. |
