Abstract
To report feedback information regarding a wireless channel a mobile station determines whether a predefined condition is satisfied. In response to determining that the predefined condition is satisfied feedback information regarding an individual one of plural subbands of the wireless channel is included in a first report to be sent to a base station. In response to determining that the predefined condition is not satisfied aggregate feedback information regarding the plural subbands is included in a second report to be sent to the base station.

Claim
1. A method of reporting feedback information regarding a wireless channel comprising:
determining, by a mobile station, whether preferred subbands of the wireless channel are not changing, wherein said determining whether the preferred subbands of the wireless channel are not changing comprises determining whether a bitmap for a current reporting interval is unchanged from a bitmap for a prior reporting interval, wherein the bitmap identifies the preferred subbands;
in response to determining that the preferred subbands of the wireless channel are not changing:
transmitting in a first report to a base station, feedback information regarding an individual one of plural subbands of the wireless channel; and
receiving, from the base station on the wireless channel, data precoded based on the first report; and
in response to determining that the preferred subbands of the wireless channel are changing:
transmitting in a second report to the base station, aggregate feedback information regarding the plural subbands; and
receiving, from the base station on the wireless channel, data precoded based on the second report.
2. The method of claim 1, wherein the aggregate feedback information includes an average of the plurality of subbands.
3. The method of claim 1, wherein determining if the bitmap identifying preferred subbands has not changed comprises determining if a number of bits that correspond to one or more of the preferred subbands has not changed.
4. The method of claim 1, further comprising:
after sending the first report, including, in a third report to be sent to the base station, further feedback information regarding a second individual one of the plural subbands if the preferred subbands of the wireless channel are not changing.
5. The method of claim 1, further comprising:
including in the first report further feedback information regarding a second individual one of the plural subbands.
6. The method of claim 1, further comprising:
performing, by the mobile station, data communication using one or more of the plural subbands that are less than all available subbands of the wireless channel.
7. The method of claim 1, wherein performing the data communication is according to a closed loop MIMO (multiple input, multiple output) mode of operation.
8. The method of claim 7, wherein the mobile station is to transmit plural codewords, and wherein the feedback information included in the first report is for a first of the plural codewords, and wherein the first report further includes feedback information for an individual subband for another one of the plural codewords.
9. The method of claim 1, wherein the feedback information in the first report for the individual subband comprises at least one of:
a precoding matrix index (PMI); and
channel quality indicator (CQI).
10. A base station comprising:
an interface to communicate wirelessly over a wireless channel with a mobile station; and
a processor configured to:
determine whether preferred subbands of the wireless channel are not changing, wherein to determine whether the preferred subbands of the wireless channel are not changing, the processor is further configured to determine if a bitmap for a current reporting interval is unchanged from a bitmap for a prior reporting interval, wherein the bitmap identifies the preferred subbands;
in response to determining that preferred subbands of the wireless channel are not changing:
using individual feedback information for an individual subband of plural subbands of the wireless channel; and
transmitting, on the wireless channel, data precoded based on the individual feedback information; and
in response to determining that preferred subbands of the wireless channel are changing:
using aggregate feedback information for the plural subbands; and
transmitting, on the wireless channel, data precoded based on the aggregate feedback information.
11. The base station of claim 10, wherein the aggregate feedback information includes an average of the plurality of subbands.
12. The base station of claim 10, wherein the individual feedback information or aggregate feedback information is used for downlink signaling and traffic data to be sent to the mobile station.
13. The base station of claim 10, wherein the individual feedback information comprises at least one of:
an individual channel quality indicator (CQI); and
an individual precoding matrix index (PMI).
14. A mobile station comprising:
an interface to communicate wirelessly over a wireless channel with a base station; and
a processor configured to:
determine whether preferred subbands of the wireless channel are not changing, wherein to determine whether the preferred subbands of the wireless channel are not changing, the processor is further configured to determine if a bitmap for a current reporting interval is unchanged from a bitmap for a prior reporting interval, wherein the bitmap identifies the preferred subbands;
in response to determining that the preferred subbands of the wireless channel are not changing:
transmit in a first report to a base station, feedback information regarding an individual one of plural subbands of the wireless channel; and
receive, from the base station on the wireless channel, data precoded based on the first report; and
in response to determining that the preferred subbands of the wireless channel are changing:
transmit in a second report to the base station, aggregate feedback information regarding the plural subbands; and
receive, from the base station on the wireless channel, data precoded based on the second report.
15. The mobile station of claim 14, wherein the aggregate feedback information includes an average of the plurality of subbands.
16. The mobile station of claim 14, wherein the first report includes a bitmap identifying the plural subbands as being preferred subbands.
17. The mobile station of claim 14, wherein the individual feedback information includes at least one of:
an individual channel quality indicator (CQI); and
an individual precoding matrix index (PMI).
18. The mobile station of claim 14, wherein to determine whether preferred subbands of the wireless channel are not changing the processor is further configured to:
determine whether the bitmap identifying the preferred subbands remains the same in successive reporting intervals.
19. The mobile station of claim 14, wherein to determine whether preferred subbands of the wireless channel are not changing comprises determining if a number of bits that correspond to one or more of the preferred subbands has not changed.
20. The base station of claim 10, wherein determining if the bitmap identifying preferred subbands has not changed comprises determining if a number of bits that correspond to one or more of the preferred subbands has not changed.
