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.
Claims22
An apparatus for wireless communication, comprising:
- a receiver configured to receive a message indicating that channel state information is requested;
- a processing system configured to generate a communication comprising a field for indicating if a first segment of channel state information of a plurality of segments of channel state information is being transmitted and a second field including three bits, wherein the field comprises one bit, and wherein the bit of the field has a value of “0” and the bits of the second field have a value of “111” if the communication does not include channel state information;
- and
- a transmitter configured to transmit the communication.

An apparatus for wireless communication, comprising:
- a receiver configured to receive a message indicating that channel state information is requested;
- a processing system configured to generate a communication comprising a first field for indicating if a first segment of channel state information of a plurality of segments of channel state information is being transmitted and a second field for indicating a number of segments of channel state information remaining to be transmitted, wherein the first field and the second field indicate null channel state information is included in the communication;
- and
- a transmitter configured to transmit the communication.
1 more element
An apparatus for wireless communication, comprising:
- a receiver configured to receive a message indicating that channel state information is requested;
- a processing system configured to generate a communication comprising a first field for indicating if a first segment of channel state information of a plurality of segments of channel state information is being transmitted and a second field for indicating a number of segments of channel state information remaining to be transmitted, wherein the first field and the second field indicate null channel state information is included in the communication if the first field indicates that a first segment of channel state information is not included in the communication and a value of the second field is at least as great as a maximum number of remaining segments;
- and
- a transmitter configured to transmit the configuration.
