A system and method for downlink feedback in communications between a station and an access point. In some embodiments, the method includes: receiving, from the access point, by the station, a null data packet announcement (NDPA) including a first number of spatial streams, and sending, by the station, to the access point, a Compressed Beamforming Report (CBR) including a second number of spatial streams, different from the first number of spatial streams; or sending, by the station, to the access point, an Operating Mode Indication (OMI) declaring a change in a station Modulation Coding Scheme (MCS) capability for a third number of spatial streams; or sending, by the station, to the access point, an Association Request including a declared Single-User (SU) MCS capability for a first bandwidth and a declared Multi-User (MU) MCS capability for the first bandwidth, the MU MCS capability being different from the SU MCS capability.

The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.
