Abstract
Certain aspects of the present disclosure relate to a technique for communicating Channel State Information (CSI) feedback. In some aspects, the CSI feedback is communicated in a very high throughput (VHT) wireless communications system.
Claims20
A method of wireless communication, comprising:
- transmitting a request for channel state information to one or more apparatuses, wherein the request comprises a field identifying each of the one or more apparatuses and indicating parameters for each of the one or more apparatuses to be used when determining the channel state information;
- and
- receiving a frame comprising channel state information from at least one of the one or more apparatuses in response to the request, the channel state information having been determined based at least in part on the parameters indicated by the request.
An apparatus for wireless communications, comprising:
- a transmitter configured to transmit a request for channel state information to one or more apparatuses, wherein the request comprises a field identifying each of the one or more apparatuses and indicating parameters for each of the one or more apparatuses to be used when determining the channel state information;
- and
- a receiver configured to receive a frame comprising channel state information from at least one of the one or more apparatuses in response to the request, the channel state information having been determined based at least in part on the parameters indicated by the request.
A computer program product for wirelessly communicating comprising a computer readable medium comprising instructions that when executed cause an apparatus to:
- transmit a request for channel state information to one or more apparatuses, wherein the request comprises a field identifying each of the one or more apparatuses and indicating parameters for each of the one or more apparatuses to be used when determining the channel state information;
- and
- receive a frame comprising channel state information from at least one of the one or more apparatuses in response to the request, the channel state information having been determined based at least in part on the parameters indicated by the request.
An access point, comprising:
- at least one antenna;
- a transmitter configured to transmit, via the at least one antenna, a request for channel state information to one or more apparatuses, wherein the request comprises a field identifying each of the one or more apparatuses and indicating parameters for each of the one or more apparatuses to be used when determining the channel state information;
- and
- a receiver configured to receive a frame comprising channel state information from at least one of the one or more apparatuses in response to the request, the channel state information having been determined based at least in part on the parameters indicated by the request.
