Abstract
Transmission patterns for pilot symbols transmitted from a mobile station or base station are provided. The pattern allows for improved receipt of the pilot symbols transmitted. In addition, schemes for improving the ability to multiplex pilot symbols without interference and/or biasing from different mobile stations over the same frequencies and in the same time slots.
Claims18
A method for estimating a channel, the method comprising:
- receiving a plurality of tiles, each of the plurality of tiles having a plurality of data symbols and a plurality of pilot symbols;
- and
- estimating the channel based on the plurality of pilot signals in the plurality of tiles.
A method of wireless communication, comprising:
- transmitting a first group of data symbols;
- and
- transmitting a first group of pilot symbols,
- wherein said first group of data symbols and said first group of pilot symbols are located in a first hop region.
An apparatus for wireless communication, comprising a transmitter operable to transmit a first group of data symbols and a first group of pilot symbols, wherein said first group of data symbols and said first group of pilot symbols are located in a first hop region.
A method of wireless communication, comprising:
- receiving a first group of data symbols and a first group of pilot symbols, said first group of data symbols and said first group of pilot symbols being located in a first hop region;
- and
- performing channel estimation based on said first group of pilot symbols.
An apparatus for wireless communication, comprising:
- means for transmitting a first group of data symbols;
- and
- means for transmitting a first group of pilot symbols,
- wherein said first group of data symbols and said first group of pilot symbols are located in a first hop region.
A computer-readable medium comprising:
- code for generating a first group of data symbols;
- and
- code for transmitting a first group of pilot symbols,
- wherein said first group of data symbols and said first group of pilot symbols are located in a first hop region.
