Claim
1. A multiple input multiple output (MIMO) system comprising:
a receiver configured to receive a first orthogonal frequency division multiplexing (OFDM) signal at a first time, the first OFDM signal comprising a set of non-pre-coded pilots transmitted from a plurality of transmit antennas, wherein the non-pre-coded pilots are useable to obtain channel measurements for each antenna of the plurality of transmit antennas and are distributed across subcarrier locations in the first OFDM signal;
a processor configured to determine feedback based on at least the non-pre-coded pilots; and
a transmitter configured to transmit the feedback to a base station;
wherein the receiver is further configured to:
receive a second OFDM signal at a second time, the second OFDM signal comprising non-pre-coded pilots and pre-coded pilots, wherein the pre-coded pilots are pre-coded for the receiver based on the feedback and are distributed across subcarrier locations of a resource assignment for the receiver in the second OFDM signal; and
recover transmitted information of pre-coded data received in the resource assignment for the receiver in the second OFDM signal using the pre-coded pilots.
2. The system of claim 1, wherein the second OFDM signal further comprises a second resource assignment for a second receiver, and wherein the second resource assignment comprises pre-coded pilots specific to the second receiver.
3. The system of claim 1, wherein the pre-coded pilots can be recovered by a particular user and the non-pre-coded pilots of the second OFDM signal can be recovered by multiple users.
4. The system of claim 1, wherein when the receiver is mobile, a number of the pre-coded pilots in a set is reduced in one of time or frequency.
5. The system of claim 1, wherein the pre-coded pilots are pre-coded by dirty-paper pre-coding.
6. The system of claim 1, wherein the transmitted info nation is recovered by, at least, an interpolation process.
7. The system of claim 1, wherein the pre-coded pilots are pre-coded by pre-coding comprising beam-forming weights.
8. The system of claim 1, wherein the pre-coded pilots are pre-coded using a flat part of a band.
9. The system of claim 1, wherein the pre-coded pilots are pre-coded using interlaced antenna pilot mapping.
10. The system of claim 1, wherein block antenna pilot mapping is employed by a receiver.
11. A method, comprising:
receiving a first orthogonal frequency division multiplexing (OFDM) signal at a first time, the first OFDM signal comprising a set of non-pre-coded pilots transmitted from a plurality of transmit antennas, wherein the non-pre-coded pilots are useable to obtain channel measurements for each antenna of the plurality of transmit antennas and are distributed across subcarrier locations in the first OFDM signal;
determining feedback based on at least the non-pre-coded pilots;
transmitting the feedback;
receiving a second OFDM signal at a second time, the second OFDM signal comprising non-pre-coded pilots and pre-coded pilots, wherein the pre-coded pilots are pre-coded based on the feedback and are distributed across subcarrier locations of a resource assignment in the second OFDM signal; and
recovering transmitted information of pre-coded data received in the resource assignment in the second OFDM signal using the pre-coded pilots.
12. The method of claim 11, wherein the pre-coded pilots can be recovered by a particular user and the non-pre-coded pilots of the second OFDM signal can be recovered by multiple users.
13. The method of claim 11, wherein the pre-coded pilots are pre-coded by dirty-paper pre-coding.
14. The method of claim 11, wherein the transmitted information is recovered by, at least, an interpolation process.
15. The method of claim 11, wherein the pre-coded pilots are pre-coded by pre-coding comprising beam-forming weights.
16. The method of claim 11, wherein the pre-coded pilots are pre-coded using a flat part of a band.
17. The method of claim 11, wherein the pre-coded pilots are pre-coded using interlaced antenna pilot mapping.
18. The method of claim 11, wherein block antenna pilot mapping is employed by a receiver.
19. An integrated circuit included in a receiver, comprising:
circuitry configured to receive a first orthogonal frequency division multiplexing (OFDM) signal at a first time, the first OFDM signal comprising a set of non-pre-coded pilots transmitted from a plurality of transmit antennas, wherein the non-pre-coded pilots are useable to obtain channel measurements for each antenna of the plurality of transmit antennas and are distributed across subcarrier locations in the first OFDM signal;
circuitry configured to receive a second OFDM signal at a second time, the second OFDM signal comprising non-pre-coded pilots and pre-coded pilots, wherein the pre-coded pilots are pre-coded for the receiver based on the feedback determined from at least the non-pre-coded pilots of the second OFDM signal and are distributed across subcarrier locations of a resource assignment for the receiver in the second OFDM signal; and
circuitry configured to recover transmitted information of pre-coded data received in the resource assignment in the second OFDM signal using the pre-coded pilots.
20. The integrated circuit of claim 19, wherein the pre-coded pilots can be recovered by a particular user and the non-pre-coded pilots of the second OFDM signal can be recovered by multiple users.
