Abstract
Certain aspects of the present disclosure relate to techniques for transmitting sounding feedback in Very High Throughput (VHT) wireless systems. The sounding feedback may be transmitted from a user station (STA), wherein the feedback may comprise a certain number of beamforming matrices and a certain number of singular values of a wireless channel associated with the STA. Further, the sounding feedback may comprise a bit for indicating whether this feedback represents a Single-User (SU) feedback or a Multi-User (MU) feedback.
Claims37
A method for wireless communications, comprising:
- generating, at an apparatus, a unified structure for a sounding feedback for single user (SU) and multi user (MU) communications, wherein the sounding feedback comprises at least one of one or more beamforming matrices or one or more singular values of a channel associated with the apparatus;
- and
- transmitting the sounding feedback over the channel.
An apparatus for wireless communications, comprising:
- means for generating a unified structure for a sounding feedback for single user (SU) and multi user (MU) communications, wherein the sounding feedback comprises at least one of one or more beamforming matrices or one or more singular values of a channel associated with the apparatus;
- and
- means for transmitting the sounding feedback over the channel.
An apparatus for wireless communications, comprising:
- a circuit configured to generate a unified structure for a sounding feedback for single user (SU) and multi user (MU) communications, wherein the sounding feedback comprises at least one of one or more beamforming matrices or one or more singular values of a channel associated with the apparatus;
- and
- a transmitter configured to transmit the sounding feedback over the channel.
A computer readable medium containing executable instructions for wireless communications, the executable instructions comprising instructions for:
- generating, at an apparatus, a unified structure for a sounding feedback for single user (SU) and multi user (MU) communications, wherein the sounding feedback comprises at least one of one or more beamforming matrices or one or more singular values of a channel associated with the apparatus;
- and
- transmitting the sounding feedback over the channel.
An access terminal, comprising:
- at least one antenna;
- a circuit configured to generate a unified structure for a sounding feedback for single user (SU) and multi user (MU) communications, wherein the sounding feedback comprises at least one of one or more beamforming matrices or one or more singular values of a channel associated with the access terminal;
- and
- a transmitter configured to transmit, via the at least one antenna, the sounding feedback over the channel.
